Thus, decaying wood might likely have measurable effects on chemical properties of the underlying soil. We hypothesized that decaying wood would have a stronger effect on soil as decomposition advances and that such effect would vary according to wood quality. Twenty logs from two species with contrasting wood properties (Dacryodes excelsa Vahl. and Swietenia macrophylla King) and at two different decay stages (6 and 15 years after falling) were selected, and soil under and 50 cm away from decaying logs was sampled for soil organic matter (SOM) fractions [NaOH-extractable and water-extractable organic matter -(WEOM)] and properties (WEOM aromaticity). NaOH-extractable C and WEOM were higher in the soil influenced by 15-year-old logs, while the degree of aromaticity of WEOM was higher in the soil influenced by the 6-year-old logs. Decaying logs did influence properties of the underlying soil with differing effects according to the species since there was more NaOH-extractable C in the soil associated to D. excelsa logs and more WEOM in the soil associated to S. macrophylla older logs. It is proposed that such effects occurred through changes in the relative quantity and quality of different SOM fractions, as influenced by species and advancement in decomposition. Through its effect on SOM and nutrient dynamics, decaying wood can contribute to the spatial heterogeneity of soil properties, and can affect process of soil formation and nutrient cycling.

The labeling system avoids the use of a chamber or other enclosure, instead distributing CO2 heavily enriched in C-13 at near atmospheric concentrations to the tree foliage through the use of porous tubing. The system was applied to three plantation grown juvenile larch ( Larix spp.) trees during the daylight hours over the course of five days in the middle of the growing season. Relative to control trees, fumigation with enriched CO2 resulted in significantly C-13- enriched foliar respiration and nighttime soil respiration. Enrichment was also created in the foliar tissue, but differences between labeled and control trees were not statistically significant. Temporal and spatial variation in the strength of the isotopic label did occur, and modifications to the system are suggested to limit the variation. The approach should enable the implementation of pulse-chase experiments designed to understand plant source-sink relationships or experiments designed to understand the flux of C from plant roots into the soil food web.

TI Incidence and ecology of Blackberry yellow vein associated virus SO PLANT DISEASE LA English DT Article DE blackberry yellow vein disease; Rubus ID CHLOROSIS VIRUS; CLOSTEROVIRUSES; EPIDEMIOLOGY; ISOLATE; TOMATO AB Symptoms of leaf vein yellowing and bush decline in blackberry were attributed to infection by a novel crinivirus named Blackberry yellow vein associated virus (BYVaV). The disease is an emerging threat to blackberry production because it can cause substantial yield loss. The objective of this study was to identify the source and means of spread of BYVaV. A survey of blackberry plants for BYVaV from wild, cultivated, and nursery stocks was conducted. Insect traps and healthy blackberry sentinel plants were placed among symptomatic plants in a production field throughout two growing seasons to monitor the occurrence of potential vectors and virus spread. Virus indicator plants were grafted with BYVaV-infected blackberry because this virus was latent in some blackberry cultivars, but indicator plants failed to express symptoms when infected with BYVaV. Reverse-transcription polymerase chain reaction detection revealed the occurrence of BYVaV in blackberry nurseries in the United States, in production fields in Arkansas, South Carolina, and North Carolina, and in wild blackberry populations in Arkansas. Whiteflies (Trialeurodes packardii and T ruborum), potential vectors of BYVaV, were observed on sticky traps placed in blackberry fields and were found colonizing blackberry plants; however, transmission studies failed to produce whitefly-mediated transmission of BYVaV. Further understanding of the disease etiology is needed to devise viable management strategies for this disease. C1 Univ Arkansas, Dept Plant Pathol, Fayetteville, AR 72701 USA.

Sporangia of metalaxyl-resistant US-8 and US-11 clonal lineages of P. infestans survived a maximum of 23 to 30 days in a Shano silt loam and a Quincy loamy fine sand. There were no significant differences between soil types in area under the spore survival curve (AUSSC) in two trials, however, sporangia of P. infestans in the Quincy sand had a significantly greater mean maximum days of sporangia survival (MDSS) than did the Shano silt loam in one of two trials. AUSSC and MDSS were significantly greater (P < 0.05) for sporangia in wet soil than in dry soil under shaded conditions. Mean AUSSC and MDSS significantly decreased (P < 0.01) under nonshaded conditions versus shaded conditions. Three metalaxyl-resistant isolates (two US-8 and one US- 11) of P. infestans did not significantly differ (P < 0.05) in AUSSC and MDSS.

T. TI Distribution and molecular characterization of resistance-breaking isolates of Beet necrotic yellow vein virus in the United States SO PLANT DISEASE LA English DT Article ID SUGAR-BEET; RHIZOMANIA RESISTANCE; PCR PRODUCTS AB Beet necrotic yellow vein virus (BNYVV) is the causal agent of rhizomania in sugar beet (Beta vulgaris). The virus is transmitted by the plasmodiophorid Polymyxa betae. The disease is controlled primarily by the use of partially resistant cultivars. During 2003 and 2004 in the Imperial Valley of California, partially resistant sugar beet cultivars with Rz1 allele seemed to be compromised. Field trials at Salinas, CA have confirmed that Rz1 has been defeated by resistance-breaking isolates. Distinct BNYVV isolates have been identified from these plants. Rhizomama-infested sugar beet fields throughout the United States were surveyed in 2004-05. Soil surveys indicated that the resistance-breaking isolates not only existed in the Imperial Valley and San Joaquin Valley of California but also in Colorado, Idaho, Minnesota, Nebraska, and Oregon. Of the soil samples tested by baited plant technique, 92.5% produced infection with BNYVV in 'Beta 6600' (rz1rz1rz1), 77.5% in 'Beta 4430R' (Rz1rz]), 45.0% in 'Beta G017R' (Rz2rz2), and 15.0% in 'KWS Angelina' (Rz1rz1+Rz2rz2). Analyses of the deduced amino acid sequence of coat protein and P-25 protein of resistance-breaking BNYVV isolates revealed the high percentage of identity with non-resistance-breaking BNYVV isolates (99.9 and >98.0%, respectively). The variable amino acids in P-25 proteins were located at the residues of 67 and 68. In the United States, the two amino acids found in the non-resistance-breaking isolates were conserved (AC). The resistance-breaking isolates were variable including, AF, AL, SY, VC, VL, and AC. The change of these two amino acids cannot be depended upon to differentiate resistance-breaking and non-resistance-breaking isolates of BNYVV. C1 USDA, Agr Res Serv, Salinas, CA 93905 USA.

ALLII; H-MUTANT BACTERIOPHAGES; BACTERIAL-BLIGHT; POLYPHASIC CHARACTERIZATION; COPPER RESISTANCE; TOMATO; FIELD; SPOT; CAMPESTRIS; BIOCONTROL AB Xanthomonas leaf blight of onion (Allium cepa), caused by Xanthomonas axonopodis pv. affli, continues to be a challenging and yield-threatening disease in Colorado and other regions of onion production worldwide. Studies were conducted to develop management strategies for this disease that are equally effective and more sustainable than the current practices of making multiple applications of copper bactericides. Mixtures of bacteriophages and the plant defense activator, acibenzolar-S-methyl, were evaluated under field and greenhouse conditions for their abilities to reduce Xanthomonas leaf blight severity. Bacteriophage populations in the phyllosphere of onion were monitored over time. Bacteriophage populations persisted on onion leaves for at least 72 to 96 h under field and greenhouse conditions, respectively. Under field conditions at one location, biweekly or weekly applications of bacteriophages reduced disease severity by 26 to 50%, which was equal to or better than weekly applications of copper hydroxide plus mancozeb. Acibenzolar-S-methyl also successfully reduced disease severity by up to 50% when used alone preventatively or followed by biweekly bacteriophage applications. Reductions in disease severity generally were not associated with improvements in onion bulb size or yield. Integration of bacteriophage mixtures with acibenzolar-S-methyl appears to be a promising strategy for managing Xanthomonas leaf blight of onion, and could reduce grower reliance on conventional copper bactericide applied with ethylenebisdithiocarbamate fungicides.

Fan, Zhaofei TI Mapping pre-European settlement vegetation at fine resolutions using a hierarchical Bayesian model and GIS SO PLANT ECOLOGY LA English DT Article DE GLO; GIS; Hierarchical Bayesian models; presettlement vegetation; Missouri ID NORTHERN WISCONSIN; USA; CLASSIFICATION; PATTERNS; RECORDS AB In the Midwestern United States, the General Land Office (GLO) survey records provide the only reasonably accurate data source of forest composition and tree species distribution at the time of pre-European settlement (circa late 1800 to early 1850). However, GLO data have two fundamental limitations: coarse spatial resolutions (the square mile section and half mile distance between quarter corner and section corner) and point data format, which are insufficient to describe vegetation that is continuously distributed over the landscape. Thus, geographic information system and statistical inference methods to map GLO data and reconstruct historical vegetation are needed. In this study, we applied a hierarchical Bayesian approach that combines species and environment relationships and explicit spatial dependence to map GLO data. We showed that the hierarchical Bayesian approach (1) is effective in predicting historical vegetation distribution, (2) is robust at multiple classification levels (species, genus, and functional groups), (3) can be used to derive vegetation patterns at fine resolutions (e.g., in this study, 120 m) when the corresponding environmental data exist, and (4) is applicable to relatively moderate map sizes (e.g., 792 x 763 pixels) due to the limitation of computational capacity. Our predictions of historical vegetation from this study provide a quantitative and spatial basis for restoration of natural floodplain vegetation. An important assumption in this approach is that the current environmental covariates can be used as surrogates for the historical environmental covariates, which are often not available. Our study showed that terrain and soil covariates least affected by past natural and anthropogenic alternations can be used as covariates for GLO vegetation mapping.

While defensins, a well-known class of such peptides, are common among eukaryotes, there are other classes restricted to the plant kingdom. These include thionins, lipid transfer proteins and snakins. In earlier work, we identified several divergent classes of small putatively secreted cysteine-rich peptides (CRPs) in legumes[Graham et al. ( 2004) Plant Physiol. 135, 1179 - 97]. Here, we built sequence motif models for each of these classes of peptides, and iteratively searched for related sequences within the comprehensive UniProt protein dataset, the Institute for Genomic Research's 33 plant gene indices, and the entire genomes of the model dicot, Arabidopsis thaliana, and the model monocot and crop species, Oryza sativa (rice). Using this search strategy, we identified similar to 13 000 plant genes encoding peptides with common features: (i) an N-terminal signal peptide, (ii) a small divergent charged or polar mature peptide with conserved cysteines, (iii) a similar intron/exon structure, (iv) spatial clustering in the genomes studied, and (v) overrepresentation in expressed sequences from reproductive structures of specific taxa. The identified genes include classes of defensins, thionins, lipid transfer proteins, and snakins, plus other protease inhibitors, pollen allergens, and uncharacterized gene families. We estimate that these classes of genes account for similar to 2-3% of the gene repertoire of each model species.

It was used to transform soybean line Asgrow 3237. Transformants bearing the mutant gene were identified by GUS expression, PCR analysis, and Southern analysis. The amount of steady state mRNA from the mutant gene in the transformed plants showed that the gene was highly expressed, but the amount of message from the unmodified Bowman-Birk gene did not change detectably. Proteins synthesized at the direction of the mutant Bowman-Birk gene accumulated in seeds of the transformed plants, and there was a marked decrease in the ability of extracts prepared from these seeds to inhibit trypsin and chymotrypsin despite the presence of Kunitz trypsin inhibitor. The more prevalent mRNA from the mutant gene was considered to out-compete message from the native genes to decrease the amount of active Bowman-Birk inhibitor.

Analyses of nucleotide substitution in coding regions suggest the two genomes diverged similar to 10 million years ago. Comparisons of transposable elements (TEs) reveal that the density of DNA TEs in O. brachyantha is comparable to O. sativa; however, the density of RNA TEs is dramatically lower. The genomic fraction of RNA TEs in japonica is two times greater than in O. brachyantha. Differences, particularly in RNA TEs, in this region and in BAC end sequences from five wild and two cultivated Oryza species explain major genome size differences between sativa and brachyantha. Gene expression analyses of three ObDREB1 genes in the sequenced region indicate orthologous genes retain similar expression patterns following cold stress. Our results demonstrate that size and number of RNA TEs play a major role in genomic differentiation and evolution in Oryza. Additionally, distantly related O. brachyantha shares colinearity with O. sativa, offering opportunities to use comparative genomics to explore the genetic diversity of wild species to improve cultivated rice.

Here we investigate how a single gene mutation altering calcium partitioning in the model forage crop Medicago truncatula affects calcium bioavailability. Previously, the cod5 M. truncatula mutant was identified which contains identical calcium concentrations to wild-type, but contains no oxalate crystals. In this study, equal number of male and female mice were randomly grouped and then fed one of four Ca-45-containing diets: M. truncatula extrinsically or intrinsically labeled, and cod5 extrinsically or intrinsically labeled. Absorption of the tracer was determined in the legs one day after consumption. The absorption was similar in the M. truncatula and cod5 extrinsically labeled diets; however, in the intrinsically labeled diets, calcium absorption was 22.87% (P < 0.001) higher in mice fed cod5. Our study presents the first genetic evidence demonstrating the nutritional impact of removing oxalate crystals from foods.

Proteins present in oxidized form in dry seeds are converted to the reduced state following imbibition. Thioredoxin (Trx) appears to play a role in this transition in cereals. It is not known, however, whether Trx-linked redox changes are restricted to cereals or whether they take place more broadly in germinating seeds. To gain information on this point, we have investigated a model legume, Medicago truncatula. Two complementary gel-based proteomic approaches were followed to identify Trx targets in seeds: Proteins were (1) labeled with a thiol-specific probe, monobromobimane (mBBr), following in vitro reduction by an NADP/Trx system, or (2) isolated on a mutant Trx affinity column. Altogether, 111 Trx-linked proteins were identified with few differences between axes and cotyledons. Fifty nine were new, 34 found previously in cereal or peanut seeds, and 18 in other plants or photosynthetic organisms. In parallel, the redox state of proteins assessed in germinating seeds using mBBr revealed that a substantial number of proteins that are oxidized or partly reduced in dry seeds became more reduced upon germination. The patterns were similar for proteins reduced in vivo during germination or in vitro by Trx. In contrast, glutathione and glutaredoxin were less effective as reductants in vitro. Overall, more than half of the potential targets identified with the mBBr labeling procedure were reduced during germination. The results provide evidence that Trx functions in the germination of seeds of dicotyledons as well as monocotyledons.

We compared sequence diversity of 30 candidate selected and 15 reference loci between the three populations of wild teosintes, maize landraces, and maize inbred lines. We inferred an approximately equal ratio of genes selected during early domestication and genes selected during modern crop breeding. Using an expanded dataset of 48 candidate selected and 658 neutral reference loci, we tested the hypothesis that candidate selected genes in maize are more likely to have transcriptional functions than neutral reference genes, but there was no overrepresentation of regulatory genes in the selected gene dataset. Electronic northern analysis revealed that candidate genes are significantly overexpressed in the maize ear relative to vegetative tissues such as maize shoot, leaf, and root tissue. The maize ear underwent dramatic morphological alteration upon domestication and has been a continuing target of selection for maize yield. Therefore, we hypothesize that genes targeted by selection are more likely to be expressed in tissues that experienced high levels of morphological divergence during domestication and crop improvement.

Silver-enhanced immunolocalization visualized with both light and transmission electron microscopy was used to determine the location of Mir1-CP in the maize leaf. The results indicated that Mir1-CP is localized predominantly in the phloem of minor and intermediate veins. After 24 h of larval feeding, Mir1-CP increased in abundance in the vascular parenchyma cells and in the thick-walled sieve element (TSE); it was also found localized to the bundle sheath and mesophyll cells. In situ hybridization of mRNA encoding Mir1-CP indicated that the primary sites of Mir1-CP synthesis in the whorl are the vascular parenchyma and bundle sheath cells. In addition to the phloem, Mir1-CP was also found in the metaxylem of the leaf and root. After 24 h of foliar feeding, the amount of Mir1-CP in the root xylem increased and it appeared to move from xylem parenchyma into the root metaxylem elements. The accumulation of Mir1-CP in maize vascular elements suggests Mir1-CP may move through these tissues to defend against insect herbivores.

TI Physical and genetic structure of the maize genome reflects its complex evolutionary history SO PLOS GENETICS LA English DT Article ID ORYZA-SATIVA L.; RICE GENOME; CEREAL CROPS; FPC MAPS; SEQUENCE; GRASSES; CLONES; ZEA; HYBRIDIZATION; DUPLICATIONS AB Maize ( Zea mays L.) is one of the most important cereal crops and a model for the study of genetics, evolution, and domestication. To better understand maize genome organization and to build a framework for genome sequencing, we constructed a sequence-ready fingerprinted contig-based physical map that covers 93.5% of the genome, of which 86.1% is aligned to the genetic map. The fingerprinted contig map contains 25,908 genic markers that enabled us to align nearly 73% of the anchored maize genome to the rice genome. The distribution pattern of expressed sequence tags correlates to that of recombination. In collinear regions, 1 kb in rice corresponds to an average of 3.2 kb in maize, yet maize has a 6-fold genome size expansion. This can be explained by the fact that most rice regions correspond to two regions in maize as a result of its recent polyploid origin. Inversions account for the majority of chromosome structural variations during subsequent maize diploidization. We also find clear evidence of ancient genome duplication predating the divergence of the progenitors of maize and rice. Reconstructing the paleoethnobotany of the maize genome indicates that the progenitors of modern maize contained ten chromosomes. C1 Univ Arizona, Arizona Genom Inst, Tucson, AZ 85721 USA.

Successful development of bioblends requires the biodegradable polymers to be compatible with other polymer components. Compatibility is normally assessed through the evaluation of the degree of intermolecular interactions between individual components. In this work, the degree of interaction in binary bioblends comprising biodegradable polycaprolactone (PCL) and polystyrene (PS) was investigated using thermogravimetric analysis (TGA), modulated differential scanning calorimetry (MDSC) and Fourier transform infrared photoacoustic spectroscopy (FTIR-PAS). The TGA studies indicated that incorporation of PCL in PS results in thermal destabilization of PCL/PS bioblends. The MDSC studies showed that some parameters, such as the enthalpies of melting and crystallization, favored partial miscibility of PS in PCL, while others, such as change in the glass transition temperature, favored immiscibility. The FTIR-PAS spectra suggested the presence of intermolecular n-pi interactions between PCL and PS and supported the results of TGA and MDSC analyses of PCL/PS bioblends. Published by Elsevier Ltd.

Quantifying the pattern of establishment of nonindigenous species across both spatial and temporal scales is paramount in early detection efforts, yet very difficult to accomplish. Previous work in epidemiology has proposed methods for assessing the space - time properties of emerging infectious diseases by quantifying the degree of space - time clustering between individual cases. I tested the applicability of one such method commonly used in epidemiology, the Knox test for space - time interaction, to analyze rare abundance data from an isolated, newly-establishing gypsy moth, Lymantria dispar, population in Minnesota, USA, and incorporated a bootstrap approach to quantify the space - time pattern in a random process that can be used to compare with results from empirical data. The use of the Knox test in assessing the establishment phase of biological invasions could potentially serve as an early warning system against new invaders, particularly for those with a known history of a repeated number of arrivals.

Chitosan, a natural biopolymer with antifungal and eliciting properties, and ethanol, a common food additive with antifungal properties, are both able to reduce postharvest decay of table grapes. The effectiveness of reduced doses of chitosan and ethanol, applied alone or in combination, to control gray mold of table grapes was evaluated. Artificially inoculated single berries or clusters were immersed in chitosan (0.1 and 0.5%), ethanol (10 and 20%), or their mixture. The combination of 0.5% chitosan with 10 or 20% ethanol improved decay control with respect to their single treatments, while combinations of 0.1% chitosan with 10 or 20% ethanol did not improve gray mold control compared to the treatments applied alone. On single berries stored 7 days at 15 +/- 1 degrees C, the highest levels of decay control were observed on grapes treated with the combination of 0.5% chitosan and 10 or 20% ethanol (reductions of 94 and 97% on cv Autumn Seedless and 69 and 73% on Thompson Seedless, respectively, compared to controls). On small clusters stored 60 days at 0.5 +/- 1 degrees C, the highest percent reduction was observed on grapes treated with the combination of 0.5% chitosan and 10 or 20% ethanol (reductions of 47 and 60% in Thompson Seedless, and 70 and 94% in Autumn Seedless, respectively, compared to controls). The tests with small clusters were carried out to simulate commercial prolonged cold storage of table grapes. The combination of reduced doses of chitosan and ethanol improved the control of gray mold of table grapes compared to their application alone, and the effect was at least additive and at times synergistic.

TI Glutathione concentration and phytotoxicity after fumigation of lemons with methyl iodide SO POSTHARVEST BIOLOGY AND TECHNOLOGY LA English DT Article DE Citrus limon; flavedo; fumigant; iodoacetamide; phytotoxicity ID BROMIDE; POSTHARVEST; ASCORBATE; QUALITY; STRESS; PLANTS; FRUIT AB Methyl bromide and its proposed replacement methyl iodide are effective quarantine fumigants, though there are phytotoxic effects for some commodities. A decrease in the level of glutathione, an important cellular protectant, has been noted in grapes and other fresh produce after fumigation with these methyl halides. In these experiments, commercial lemons were treated with methyl iodide at 28 g m(-3) for 2 h at 21 degrees C then were forcibly aerated for 2 or 24 h at 30 degrees C. Total and oxidized glutathione concentrations were determined enzymatically immediately after aeration and after 3 weeks storage at 5 degrees C. Total glutathione content was substantially reduced in comparison to controls after fumigation and 2 h aeration, but recovered considerably during a 24 h forced aeration. After 3 weeks storage, fruit subjected to a 24 h aeration had glutathione levels equivalent to those of the controls while those given a 2 h aeration had lower levels of total glutathione. This is the first demonstration of recovery of glutathione concentrations in a fresh commodity after methyl halide fumigation. Also, after 3 weeks storage, phytotoxicity in fruit given a 2 h aeration was high whereas fruit given a 24 h aeration had less injury. Fruit given a 30 degrees C aeration had less injury than that given a 21 degrees C aeration in earlier work. (C) 2007 Elsevier B.V. All rights reserved.

They were also compared for corticosterone (CORT) levels and heterophil:lymphocyte ratios (H:L) at 15 wk of age in response to an Escherichia coli challenge followed by transport stress. Large commercial(COMM) line birds were faster and more active in the T-maze at d 2 than egg-line birds. Male COMM-line birds were faster than male egg-line birds when tested in an open field at d 8. Egg-line birds had more sleeping behavior after moving to a new floor pen as compared with both an intermediate-sized line (F line) and the COMM line. Transport stress increased CORT levels in all 3 lines, and the increase was greater in males compared with females. The egg line had higher basal CORT levels (P = 0.03) and higher levels after transport (P < 0.0001). The H:L ratios were affected by both transport stress and line but not by sex. The H:L ratio was lower in the egg line as compared with both the F line and the COMM line (P < 0.0001), with the COMM line having the greatest increase in response to transport. These data, combined with those from previous studies of these lines, suggest that differences in activity of fast-growing turkeys may be used to select birds that are less susceptible to inflammatory bacterial disease and that the H:L ratio may be more useful than serum CORT in evaluating the deleterious effects of stress.

The effect of beak trimming on bird well-being depends on multiple factors, including the amount of beak that is trimmed and the quality of the procedure. The aim of this work was to determine if a relationship existed between BW and beak characteristics in 1-d-old chicks, with a future aim to develop an automated system for standardizing beak trimming. Three hundred forty-four 1-d-old chicks (Hy-Line W-36) were sorted into 3 categories based on their BW (heavy, intermediate, and light), and their beaks were photographed. Dimensional measures of beaks, including the lengths of the culmen, gonys, maxillary tomia, mandibular tomia, and the width of the upper mandible and lower mandible measured at 2, 3, and 4 mm from the tip of the upper and lower beaks, were calculated using imaging software. Correlations between BW and beak measures were evaluated using Pearson product-moment, Spearman rank-order, Kendall's tau, and Hoeffding's dependency tests. Results showed there were no significant correlations between beak dimensions and BW in the light BW group. In contrast, correlations were present between BW and the width of the upper mandible measured at 4 mm from the tip of the upper beak (P < 0.05) and the width of the lower mandible measured 2 to 4 mm from the tip of the lower beak (P < 0.05) in the intermediate BW group. In the heavy BW group, BW was positively correlated with mandibular tomia, gonys, and the width of the lower mandible measured at 2 mm from the tip of the lower beak (P < 0.05). However, in general, these correlations were too low (all below 0.23) to have any practical use for predicting beak size. Overall, the data indicated that BW cannot be used as a reliable predicator of beak size in 1-d-old Hy-Line W-36 chicks. C1 USDA, Livestock Behav Res Unit, ARS, W Lafayette, IN 47907 USA.

Diets were moderate (174 mEq/kg) or high (241 mEq/ kg) DEB formulated by altering Na-K-Cl based on actual analysis. The experiment was designed as a split plot, with the main unit consisting of 4 treatments and the factorial treatment structure arranged in a completely randomized design. Osmotic pumps delivered 8 IU of ACTH in saline/kg of BW per d for 7 d, or the same saline volume as used in ACTH at 1 mu L/h for 7 d was implanted on d 35. Venous blood samples were collected on d 35 before the pumps were implanted and on d 42 and 49. Birds fed the high DEB diet exhibited significantly higher Na+ and Ca (2+) levels than birds provided the moderate DEB diet on d 35. Infusion of ACTH significantly increased (P <= 0.05) hematocrit, hemoglobin, partial pressure Of CO2 (pCO(2)), corticosterone, osmolality, and HCO3- and reduced pH, BW, partial pressure of O-2 (pO(2)), and plasma concentrations of Na+ and Cl- in both diets compared with the control group on d 42. Similarly, the ACTH treatment significantly increased hematocrit, hemoglobin, Ca 2+, corticosterone, and osmolality and reduced (P <= 0.05) pO(2), glucose, and BW on d 49. The diet formulated for high DEB partially lowered pCO(2) on d 42. Significant DEB x ACTH interactions were observed for pCO(2) and pO(2) on d 49. However, there was a reduction in pO(2) along with a concomitant increase in erythropoiesis under the ACTH treatment for both diets, compared with the saline control, because of the increased need for O-2 to support gluconeogenic energy production. This adaptive response provided greater numbers of erythrocytes and thus a higher amount of circulating hemoglobin to deliver O-2 for metabolism. The diet formulated for high DEB partially attenuated the adaptive stress condition in broiler chickens. C1 USDA ARS, S Cent Poultry Res Lab, Mississippi State, MS 39762 USA.

Egg refrigeration restricts both penetration and growth, but a recently proposed national Salmonella Enteritidis control program would allow unrefrigerated ambient temperature storage of eggs on farms for up to 36 h. The present study used an in vitro egg contamination model to assess the ability of small numbers of 4 Salmonella Enteritidis strains and 4 Salmonella Heidelberg strains to penetrate the vitelline membrane and multiply inside yolks during 36 h of storage at either 20 or 30 degrees C. After inoculation onto the exterior surface of the vitelline membrane, all 8 Salmonella strains penetrated to the yolk contents (at a mean frequency of 45.1%), and most strains grew to significantly higher levels (with a mean log(10) bacterial concentration of 2.2 cfu/mL) during incubation at 30 degrees C. Significant differences in penetration frequency and yolk multiplication were observed between individual strains and between serotypes (Salmonella Enteritidis > Salmonella Heidelberg for both parameters). Penetration and multiplication were significantly less frequent during incubation at 20 degrees C. These results demonstrate that controlling ambient temperatures during prerefrigeration storage may be an important adjunct to prompt refrigeration for limiting Salmonella growth in eggs and thereby for preventing egg-transmitted human illness.

In experiment 1, coliforms and Escherichia coli were determined by the whole-carcass rinse (WCR) method and by scraping the skin surface and rinsing the blade (BR). In each of 2 replicate trials, 4 prechill broiler carcasses were collected from 2 different commercial processing plants. The WCR method was conducted on each carcass, then a blunt edge blade was used to scrape an area measuring approximately 80 cm 2 of the breast (front) skin and on the back of the carcass. After scraping, each blade and adhering residue was rinsed in 30 mL of 0.1% peptone. One milliliter of rinsate each from the WCR and BR was plated to determine total coliforms and E. coli. In experiment 2, 6 carcasses were collected from a processing plant in each of 2 replicate trials. Carcasses were split, with one half scraped on all skin surfaces, and the other half remaining unscraped as a control; all halves were then subjected to half-carcass rinses using 200 mL of 0.1% peptone. Coliforms and E. coli were enumerated. Results from both experiments are reported as log cfu/mL. In experiment 1, mean coliform WCR counts (5.1) were significantly higher (P < 0.05) than back BR (2.8), which were higher than front BR (2.2). Mean E. coli WCR counts (4.5) were higher than back BR (2.4), which were higher than front BR (1.6). The counts for BR adjusted for the greater surface area sampled by WCR were still lower than the WCR counts. Experiment 2 results showed no difference between control and scraped carcass halves for coliforms (4.7) or E. coli (4.6). Overall, results showed that scraping either prior to or after rinsing did not increase enumeration of coliforms or E. coli. Scraping could be a viable method to compare the numbers of bacteria on different areas of the same carcass. C1 USDA ARS, Richard B Russell Agr Res Ctr, Athens, GA 30605 USA.

This may not hold true for some poultry species intensively selected for such economically important traits as growth and meat production. For example, the modern commercial broiler breeder does not adequately control voluntary feed intake to meet its energy requirements and maintain energy balance. As a consequence, feeding must be limited in these birds to avoid overconsumption and excessive fattening during production. It is important to determine a genetic basis to help explain this situation and to offer potential strategies for producing more efficient poultry. This review summarizes what is currently known about the control of feed intake and energy expenditure at the gene level in birds. Highly integrated regulatory systems have been identified that link the control of feeding with the sensing of energy status. How such systems function in poultry is currently being explored. One example recently identified in chickens is the adenosine monophosphate-activated protein kinase pathway that links energy sensing with modulation of metabolic activity to maintain energy homeostasis at the cellular level. In the hypothalamus, this same pathway may also play an important role in regulating feed intake and energy expenditure commensurate with perceived whole body energy needs. Genes encoding key regulatory factors such as hormones, neuropeptides, receptors, enzymes, and transcription factors produce the molecular components that make up intricate and interconnected neural, endocrine, and metabolic pathway networks linking peripheral tissues with the central nervous system. Moreover, coordinate expression of specific gene groups can establish functional pathways that respond to and are regulated by such factors as hormones, nutrients, and metabolites. Thus, with a better understanding of the genetic and molecular basis for regulating feed intake and energy expenditure in birds important progress can be made in developing, evaluating, and managing more efficient commercial poultry lines.

Many chicken pathogens enter the host through the gastrointestinal tract, and over the past few decades, in-feed antibiotics and active vaccination have been the 2 main mechanisms of disease control. However, increasing public concerns are prompting government regulations on the use of growth-promoting drugs in animal production, and the ability of current vaccines to protect against emerging hypervirulent strains of pathogens is becoming an issue. Therefore, there is a need to develop alternative control strategies against poultry pathogens of economic importance as well as to carry out basic research to enhance understanding of host-pathogen interactions at local sites of infection. Effective control strategies against pathogens can only be accomplished by comprehensive analysis of the basic immunobiology of host-pathogen interactions. Recent sequencing of the poultry genome and the availability of several tissue-specific cDNA microarrays are facilitating the rapid application of functional immunogenomic technologies to poultry disease research. Studies using functional genomic, immunology, and bioinformatic approaches have provided novel insights into disease processes and protective immunity to chicken pathogens. In this review, we summarize recent published literature concerning the host response to Eimeria and Salmonella infections with emphasis on our studies using immunogenomic tools to investigate and characterize the mechanisms of avian immunity to these mucosal pathogens. The results clearly indicate that this immunogenornic approach will lead to increased understanding of immune responses to infectious agents that will enable the development of effective prevention strategies against mucosal pathogens.

The endoglucanase portion of the gene was expressed in Escherichia coli, but soluble activity in cell lysates was due to a truncated enzyme with an apparent mass of 42 kDa, the equivalent of the predicted catalytic domain. Insoluble protein renatured from inclusion bodies was protected against truncation, yielding an active holoenzyme (rCel5A) with apparent mass of 62 kDa. The recombinant rCel5A was optimally active at 65 degrees C and PH 6.0, but retained only 10% activity after 1 h incubation at this temperature. At 55 degrees C, rCel5A had a broad pH range for activity and stability, with greater than 75% relative activity from PH 4.5-7.0, and retaining greater than 80% relativity activity across the range PH 4.5-8.0 following 1 h incubation at 55 degrees C. It readily hydrolyzed pNPC, carboxymethylcellulose, barley beta-glucan, and lichenan, but despite binding to cellulose, had only weak activity against avicel. Hydrolysis products from soluble polysaccharides included glucose, cellobiose, cellotriose, and cellotetraose. The catalytic properties, broad PH range and thermostability of the recombinant B. licheniformis endoglucanase may prove suitable for industrial applications. Published by Elsevier Ltd.

Expression of this genetic trait was developmentally programmed. After the tillering stage, small red and brown lesions were initiated in groups on the leaf blade. Eventually, the lesions formed parallel lines along the midrib of the leaf Under light and transmission electron microscopy, we observed that thylakoid membranes of mesophyll chloroplasts were progressively damaged in the nonspotted section of the mutant leaf. However, chloroplasts were absent in the mesophyll cells of the spotted area of the spl6 mutant. These results indicated that lesion formation of the spl6 mutant might be caused by oxidative burst. Proteome analysis revealed that 159 protein spots were up or downregulated in comparison between spotted leaves of the spl6 mutant plants and normal leaves of the wild type. Among them, protein disulfide isomerase (PDI), transketolase, thioredoxin peroxidase (TPX), ATP synthase, RuBisCO large subunit, and RuBisCO activase small subunit were not identified in the spl6 mutant but were abundant in the wild type. Especially, the absence of TPX and PDI might be the cause of the failure to protect cells against oxidative burst resulting in degradation of the thylakoid membranes and leading to programmed cell death and lesion development.

TI GPS error in studies addressing animal movements and activities SO RANGELAND ECOLOGY & MANAGEMENT LA English DT Article DE global positioning system collars; grazing behavior; cattle; activity; data filtering; technique; method; differential correction ID CATTLE DISTRIBUTION; COLLAR; PERFORMANCE; SYSTEM AB Global Positioning System (GPS) error, associated with free-ranging animal studies, remains a concern in range/animal research. For distance measures, errors may be additive over time and increase as sampling frequency intensifies. The first study assayed effects of coordinate integration time (10 hourly intervals), 10 GPS collars, and range of unit movement (0 to 90 m in 10-m intervals as treatments) on bias of GPS measures of distance. "Bias" was the difference between measured distances and distances derived from GPS coordinates of units moved over a surveyed grid. A second study evaluated four methods (regression modeling, minimum distance threshold, motion sensor threshold, and a combined minimum distance/motion sensor technique) for extracting perceived movements from GPS data acquired from cattle. A classification assessment compared observation data of cattle with their corresponding GPS records after filtering by the four techniques. Except for immobile GPS collars in study 1, bias of distance measures was inconsequential for movements ranging from 10 to 90 m (differentially corrected mean bias = 0.18 m +/- 0.12 m SE). When collars were immobile, GPS error generated about 1.7 m +/- 0.7 in SE of perceived travel per record with postdifferentially corrected coordinates (P < 0.05), and 3.9 m +/- 0.8 m SE with uncorrected data. At specific times, post-differential correction failures can affect (P <= 0.05) GPS measures of distance. Using any of four proposed techniques, one may effectively filter data sets to remove perceived travel accrued when cattle were resting with 81% to 92% of resting intervals correctly classified. The most effective regression technique suggested cattle travels were overestimated by about 15.2% or 1.15 km daily without filtering.

TI Revegetating Russian knapweed (Acroptilon repens) infestations using morphologically diverse species and seedbed preparation SO RANGELAND ECOLOGY & MANAGEMENT LA English DT Article DE invasive weeds; seedbed preparation; seedling establishment; weed control ID INFESTED RANGELAND; DIFFUSE KNAPWEED; LEAFY SPURGE; GRASSLAND; BIODIVERSITY; INVASIBILITY; RESISTANCE; INVASION AB Highly degraded pastures and rangeland dominated by Russian knapweed (Acroptilon repens [L.] DC) are often devoid of desirable plants. Control efforts may be ephemeral because propagules of desirable species are not available to reoccupy niches made available by control procedures. Establishing desirable, competitive plants is essential for enduring management and restoration of Russian knapweed and other weed-infested plant communities. The objective of this study was to investigate the effectiveness of revegetating Russian knapweed-infested pastures with 3 nonnative, morphologically diverse species following 1 of 3 seedbed preparation treatments. In successive years, at 2 similar sites in southeastern Oregon, we sprayed Russian knapweed with glyphosate, then prepared the seedbed by burning, tilling, or leaving untreated. Following seedbed preparation, we seeded a perennial forb (alfalfa [Medicago sativa L.]), a bunchgrass (Siberian wheatgrass [Agropyron fragile {Roth} P. Candargy subsp. sibericum {Willd.} Melderis]), and a sod-forming grass (pubescent wheatgrass [Elytrigia intermedia {Host} Nevski subsp. tricbopbora {Link} Tvzel]) in monocultures and 2- and 3-species mixtures. We measured Russian knapweed and seeded-species density 1 and 2 years following seeding. The forb-seeding treatment decreased reinvasion of Russia knapweed by 50%-60% at 1 site, but otherwise, seeding treatment had little influence on total seeded-species density or Russian knapweed density. Tilling generally resulted in a 35%-40% reduction in Russian knapweed density compared with the control and resulted in the highest establishment of seeded species. Variability in annual precipitation appeared to influence seeded-species establishment between the sites. Our results suggest shallow tilling (10-15 cm) followed by drill-seeding desirable forbs and grasses may provide the best results when revegetating Russian knapweed infestations. Follow-up management should include strategies to enhance desirable species production while minimizing Russian knapweed reinvasion. C1 USDA, Agr Res Serv, E Oregon Agr Res ctr, Burns, OR 97720 USA.

We examined the effects of wildfires and environmental conditions on the ability of rush skeletonweed (Chondrilla juncea L.), a perennial Eurasian composite, to invade degraded sagebrush steppe communities, largely dominated by cheatgrass (Bromus tectorum L.). Recruitment of rush skeletonweed from seed and root buds was investigated on 11 burned and unburned plot pairs on Idaho's Snake River Plain following summer 2003 wildfires. Emergence from soil seedbanks was similar on burned and unburned plots in 2003 and 2004 (P = 0.37). Soils from recently burned plots (P = 0.05) and sterilized field soil (P < 0.01) supported greater emergence than did unburned field soils when rush skeletonweed seeds were mixed into the soils in the laboratory. These decreases may indicate susceptibility of this exotic invasive to soil pathogens present in field soils. Seeds in bags placed on field soil in late October 2003 reached peak germination by mid-January 2004 during a wet period; 1% remained viable by August 2004. Seedling emergence from sown plots or the native seedbank and establishment of new rosettes from root sprouts in 2003-2005 indicate that seed germination of rush skeletonweed on the Snake River Plain may be facultative, occurring in fall or spring if soil moisture is adequate, although many germinants may not survive. Stand development results primarily from root sprouting. Establishment from seed is episodic but provides for dispersal, with increasing fire frequency and size expanding the areas of disturbance available for new invasions.

TI A basis for relative growth rate differences between native and invasive forb seedlings SO RANGELAND ECOLOGY & MANAGEMENT LA English DT Article DE nutrients; specific leaf area; weeds; yarrow ID NET ASSIMILATION RATE; LEAF-AREA; PLANT INVASIVENESS; FIELD AB The ability of invasive plants to achieve higher relative growth rates (RGR) than their native counterparts has been widely documented. However, the mechanisms allowing invasives to achieve higher RGR are poorly understood. The objective of this study was to determine the basis for RGR differences between native and invasive forbs that have widely invaded nutrient-poor soils of the Intermountain West. Six native and 6 invasive forbs were seeded in pots in a greenhouse, and 4 harvests were conducted over a 2-month period. These 4 harvests were used to calculate RGR and the components of RGR, net assimilation rate (rate of dry matter production per unit leaf area), leaf area ratio (LAR, leaf area per unit total plant mass), leaf mass ratio (the proportion of biomass allocated to leaves), and specific leaf area (SLA, leaf area per unit leaf biomass). Mean RGR of the 12 study species ranged between 0.04 and 0.15 g.g(-1).d(-1) but was significantly higher for invasive forbs compared to native forbs (P = 0.036). The higher RGR achieved by invasive forbs was due mainly to a greater SLA and LAR. This indicates that invasive forbs achieved higher RGR than natives primarily by creating more leaf area per unit leaf mass, not by allocating more biomass to leaf tissue or by having a higher net rate of dry matter production. A high degree of variation in RGR, SLA, and LAR was observed in native forbs, suggesting that the ability to design weed-resistant plant communities may be improved by managing for specific functional traits as opposed to functional groups.

TI Toxic alkaloid concentrations in Delphinium nuttallianum, Delphinium andersonii, and Delphinium geyeri in the intermountain region SO RANGELAND ECOLOGY & MANAGEMENT LA English DT Article DE diterpenoid alkaloids; cattle; larkspur; poisonous plants; methyllycaconitine ID TALL LARKSPUR DELPHINIUM; NORDITERPENOID ALKALOIDS; CATTLE; BARBEYI AB Low larkspurs (Delphinium nuttalliunum Pritz., Delphinium andersonii Gray) and plains larkspur (Delphinium geyeri Greene) often poison cattle grazing on western North American rangelands. The dominant toxic alkaloid in larkspur is methyllycaconitine (MLA); other very toxic alkaloids in low and plains larkspurs are nudicauline and geyerline. Toxic alkaloid concentrations in larkspur near or above 3 mg.g(-1) present significant risk to grazing cattle. D. nuttallianum from Utah and Colorado, D. andersonii from northern Arizona, and plains larkspur (D. geyeri) from Wyoming were collected for analysis. Concentrations of MLA in D. nuttallianum ranged from 0.8 to4.5 mg.g(-1) inUtah and Colorado; total toxic alkaloid concentrations were often above 3 mg.g-1. D. nuttallianum differed (P = 0.09) in MLA concentration between locations but not phenotogical stages (P = 0.41). Concentrationsof nudicauline ranged from 0.7 to 4 mg.g(-1) 1 in D. nuttallianum and were different (P = 0.01) between locations and phenological stages (P = 0.004). D. andersonii was consistently toxic because the total toxic alkaloid concentration fluctuated from 3 to 6 mg.g(-1) over the growing season. The concentration of geyerline in D. andersonii was equal to or greater than MLA at each phenological stage, thus adding to the toxicity. The concentration of toxic alkaloids in D. geyeri was typically highest (2-4 mg.g(-1)) in immature plants, although toxic alkaloid concentrations in plants during the pod stage of growth sometimes increased. Only trace amounts of nudicauline were found in D. geyeri, as most of the alkaloid fraction was other N-(methylsuccinimido) anthranoyllycoctonine (MSAL) alkaloids. Total alkaloid concentration (MSAL and non-MSAL alkaloids) in D. geyeri sometimes exceeded 15 mg.g-1. Concentrations of toxic alkaloids in D. nuttalliunum, D. andersonii, and D. geyeri often did not significantly decline during the growing season as typically found in tall larkspurs. Thus, risk to grazing cattle may remain high until these plants are dormant. C1 USDA ARS, Poisonous Plant Res Lab, Logan, UT 84341 USA.

Inhalation exposures were performed in a closed tent for the allotted times. The amount of endotoxin calculated to be in the dust was shown to be 26.9 mu g/g. The amounts of dust introduced into the tent for each time period were 4.58 g/m(3) of air for 15 min; 7.46 g/m(3) of air for 1 h; 14.82 g/m(3) of air for 3 h; and 40.60 g/m(3) of air for 4 h. There was a significant increase in the white blood cell count in the animals dusted for 4 h, at 8 and 12 h following exposure. There was a significant decrease in the peripheral lymphocyte cell count following the 15 min exposure at 12 h post exposure, and there was a significant increase in the peripheral lymphocyte cell count following the 4 h exposure, 24 h after the exposure. There was a significant increase in the neutrophil cell count 8 and 12 h following the 4 h exposure, while there was a significant decrease in the neutrophil cell count 48 h following the 4 h exposure. There was a significant increase in the rectal temperatures of all goats receiving the 4 h dust exposure at all time periods (0 time, 4, 12, 24, and 48 h). There was a significant increase in the rectal temperatures of goats following the 1 h exposure, 8 h later. These results indicate that the larger the dose of inhaled endotoxin, the higher the resultant fever and leukocytosis. Published by Elsevier B.V.

The experiment consisted of four simultaneous crossovers, with 21 d for adaptation before measures. Diets were 60% concentrate (CON: 15% CP) and ground alfalfa hay (FOR: 23% CP), offered in two meals at 8:00 and 16:00 h. Energy expenditure was determined from O, consumption and production of CO, and CHa over 2-day periods in fed and fasting states (total 4-day fasting period). Fasting EE was higher during the day than night, with values generally highest at 16:00-17:00h. Animal within breed affected EE, HR and EE:HR (P<0.05). The diurnal pattern in EE varied with diet (P<0.05), although total daily EE was not different between diets. Before the morning meal, there were a number of hours during which EE was greater for CON than for FOR. However, at both meals the rise in EE was considerably greater for FOR versus CON, lasting for 3-4 h. The same general pattern in HR was observed, although the period of time when there was a dietary difference after the afternoon meal was shorter. For both fed and fasted goats, EE:HR differed among hours of the day (P < 0.05). EE:HR tended (P < 0.09) to differ between diets (5.99 and 6.21 for CON and FOR, respectively) and to be affected (P < 0.09) by an interaction between breed and diet (AL: 5.84 and 6.38; AN: 5.91 and 5.73; BO: 6.05 and 6.58; and SP: 6.17 and 6.15 kJ/(kg B W 75 x day):heart beats/min) for CON and FOR, respectively. In conclusion, for use of HR to predict EE by goats, it appears desirable to determine the ratio of EE:HR with a diet similar to that consumed during prediction and over an extended period of time.

The cheeses were manufactured from milk from Alpine goats and based on the procedures of Cheddar and Colby cheese manufacture. In Cheddar-like cheese, the sliceability (force required to slice sample) was at its highest when the cheese was made with milk from weeks 12-15 into lactation. Color change was variable although it tended to be lowest in cheese made at weeks 4-5 into lactation. In Colby-like cheeses, meltability was at its highest and sliceability was very poor (after 8 weeks of aging) when made with milk obtained later in lactation. Color changes were variable at the two different baking temperatures. As expected during aging, the meltability of the cheeses increased and the force required to slice the cheeses decreased with the significant changes occurring within the first 16 weeks for Cheddar-like and the first 8 weeks for Colby-like cheeses. The color changes upon heating were variable for aged Cheddar-like cheeses and did not change significantly for aged Colby-like cheeses. Color changes were highly correlated with proteolysis occurring during storage. Cheese milk obtained at different times of lactation and aging of the cheese impact the functional properties of caprine milk cheeses and will affect their optimal utilization.

TI Increased abundance of arbuscular mycorrhizal fungi in soil coincides with the reproductive stages of maize SO SOIL BIOLOGY & BIOCHEMISTRY LA English DT Article DE AM fungi; FAMEs; bray P; maize (Zea mays L.) ID FATTY-ACID SIGNATURES; MICROBIAL COMMUNITIES; PHOSPHORUS-NUTRITION; ELECTRICAL-CONDUCTIVITY; CARBON; CORN; COLONIZATION; BIOMASS; GROWTH; ACCUMULATION AB Arbuscular mycorrhizal (AM) fungi are recognized for their positive effects on plant growth, playing an important role in plant P nutrition. We used C16:1cis11 and C18:1cis11 fatty acid methyl ester (FAME) biomarkers to monitor the dynamics of AM fungi during the reproductive stages of maize (Zea mays L.) grown at high yield in Nebraska, USA. Two fields with four different levels of P availability were sampled throughout the reproductive stages. Chambers, made of PVC enclosed mesh fabric to allow passage of roots and hyphae (+R) or hyphae alone (-R) and amended with either KH2PO4 (+P) or distilled water (-P), were installed in the field at tasselling and removed after three, six and nine weeks. Our objectives were (i) to provide evidence for C allocation to AM fungi during the reproductive stages of high productivity maize and (ii) to link AM fungal growth dynamics with changes in soil P availability. We observed that initial AM FAME concentration was lower at sites with a high availability of P. During the reproductive growth of maize, AM biomarkers increased inside the chambers and were consistent with the biomarker increase observed in adjacent field soil. This confirms that there is C allocation from the plant to the symbiont during the reproductive stages of maize. We also observed a reduction in available P in +R and -R chambers. This observation implies that hyphae were as efficient as roots and hyphae in reducing the P concentration in chambers. These results demonstrate that AM fungi are active during the reproductive growth stages of maize and may benefit high productivity maize crops by facilitating P uptake. (c) 2007 Elsevier Ltd.

TI Distribution of the arbuscular mycorrhizal biomarker C16 : 1cis11 among neutral, glyco and phospholipids extracted from soil during the reproductive growth of corn SO SOIL BIOLOGY & BIOCHEMISTRY LA English DT Article DE mycorrhiza; AM fungi; C16 : 1cis11; FAME; El-FAME; CM-FAME; NLFA; GLFA; PLFA; corn ID FATTY-ACIDS; FUNGI; MYCELIUM; SPORES; ROOTS; BIOMASS; HYPHAE AB Arbuscular mycorrhiza (AM) fungi form symbiotic relationships with the majority of land plants and are known for their positive effects on plant P acquisition and soil quality. The extramatrical growth of the mycelium is a key factor in nutrient acquisition by the symbiont. Soil grinding and extraction/fractionation of lipids were used in a field experiment to identify probable sources of the AM biomarker C16:1cis11 and its functional significance during reproductive growth of corn (Zea mays L.). Chambers, enclosed with a 1 mm mesh fabric to allow roots and hyphae to pass into the enclosed soil volume, were installed in two field sites cropped to continuous corn in central Nebraska. The chambers were installed at tasselling and removed after 3, 6 and 9 weeks. Soil from the chambers was analyzed by ester-linked fatty acid (EL-FAME) and chloroform-methanol fatty acid (CM-FAME) analysis. We also separated and analyzed the neutral lipid (NLFA), glycolipid (GLFA) and phospholipid (PLFA) fatty acid fractions. Roller milling the soil gave up to two-fold increases in the recovery of EL- and CM-FAMEs common to saprophytic fungi (C16:0, C18:1cis9, C18:2cis9,12) and AM fungi (C16:0, C16:1cis11, C18:1cis11) but not those specific to bacteria or fauna. Resistant AM fungal structures were enriched in NLFA and GLFA C16:1cis11, but not PLFA, indicating that storage lipids and possibly cell-wall lipids are released by roller milling. Similar proportional increases in C16:1cis11 on roller milling indicates that mild alkaline hydrolysis (EL-FAME) is as inefficient as chloroform-methanol (CM-FAME) in extracting lipids from AM spores. EL- and CM-FAME C16:1cis11 increased by one-third between R5 and R6, indicating C allocation from the plant to the AM fungus during the reproductive stages of corn. This increase was attributed to accumulation of NLFA and GLFA in lipid-containing structures of the extramatrical mycelium and AM structures within roots, not increased sporulation. We propose EL-FAME C16:1cis11 as a simple measure of AM biomass in soils that largely reflects the AM hyphal network important to nutrient acquisition by the plant. (c) 2007 Elsevier Ltd.

These spectroscopic studies generally rely on the reference spectra of model compounds. However, such reference information is limited, especially for metal phytate compounds, which are an important component of many samples (e.g., 60-80% of soil organic P). In this study, we used solid-state FT-IR and 31P MAS NMR to examine metal phytates and their orthophosphate counterparts, as well as several pyrophosphates and polyphosphates. Comparisons of the FT-IR spectra of metal orthophosphates and phytates demonstrated distinct characteristics and differences. The triplet-peak feature in the 790- to 900-cm(-1) range could be used to distinguish metal phytates from other P compounds that contained one or no peak in the same range. FT-IR spectral features centered at 1100 cm 1 (i.e., broad or splitting multiple peaks) could distinguish among different metal phytate compounds. We observed that the solid-state 31P NMR peaks of phytate compounds were broad, whereas those of inorganic P compounds were much sharper. We propose that the same attention should be paid to spinning sidebands as on the main peaks, because the features of spinning sidebands were unique for some P compounds. Finally, our observations indicated that wetting samples could change both intensity and position of chemical shifts and spinning sidebands, thus keeping samples dry is necessary to obtain repeatable and high-quality solid-state 31P MAS NMR spectra. The solid-state FT-IR and 31P NMR reference spectra established in this work may help in basic and applied environmental soil P studies by the two advanced spectroscopic technologies.

Recent studies have found the herbicide norflurazon [4-chloro-5-(methylamino)-2-(3-(trifluoromethyl)phenyl)-3-(2H)-pyridiazone] in groundwater and surface water. Although there are data on the sorption, degradation, and mobility of this compound in different soils, none address effects of tillage on its fate. Also, the accuracy of independent sorption and degradation data for predicting norflurazon mobility has not been assessed. This study compared sorption, degradation, and mobility of norflurazon in Dundee (fine-silty, mixed, thermic, Aeric Ochraqualfs) soil from conventional-tillage (CT) and no-tillage (NT) plots of a longterm tillage experiment. Sorption was determined for the 0- to 10-, 10- to 20-, and 20- to 30-cm depths of these soils in a 24-h batch equilibration study. Sorption was well-described by the Freundlich model and related to soil organic C, being greater in surface NT than CT soil and generally decreasing with depth. Degradation was tracked in dosed (0.256 mu mol/25 g; C-14-labeled) soil samples for 14, 28, 56, and 112 days, followed by methanol extraction and high-performance liquid chromatography analysis. Norflurazon degraded with formation of desmethyl-norflurazon, nonextractable C-14 residue, and loss of (CO2)-C-14. Degradation rate was adequately described by first-order models and decreased with depth but was not affected by tillage. Rate constants ranged from 0.012 to 0.005 day(-1). Mobility in intact cores (similar to 30 cm long) of CT and NT soil showed less mass eluted from and greater retention in NT cores, consistent with greater sorption. Transport showed preferential flow (Br tracer) that was described by a mobile/immobile water model. Norflurazon mobility could be reasonably well described using the batch sorption and degradation data. C1 Louisiana State Univ, AgCtr, Dept Agron & Environm Management, Baton Rouge, LA 70803 USA.

Corn stover is rich in cellulose and hemicellulose, both of which can be converted to sugars and fermented to ethanol. This fermentation process results in a high-lignin fermentation byproduct (HLFB) that could be converted to energy products or used as a soil amendment. We had two objectives: (i) to determine whether HLFB (0.1, 1.0, or 10 kg m(-2)) could improve soil properties in two soils with contrasting levels of soil organic carbon (SOC); and (ii) to assess the impact of HLFB on crop growth. These goals were addressed with separate experiments. In the soil experiment, two soils were amended with HLFB or ground corn (Zea mays L.) stover and then incubated in pots for 118 d. Flux of COZ was monitored and soil properties were measured after incubation. In the plant experiment, corn and soybean [Glycine max (L.) Merr.] were grown in pots, without amendment or amended with 1.0 kg m(-2) corn stover or 1.0 kg m(-2) HLFB. The soil experiment indicated that the addition of 10 kg m(-2) HLFB increased CO2 emission, humic acid concentration, and water-stable aggregates, and decreased bulk density (D-b). No adverse impacts on crop growth were measured when HLFB was applied at a rate of 1.0 kg m(-2). Much of the HLFB may be used by the energy industry; but perhaps a percentage could be returned to the field to reduce the impact of corn stover removal on soil C.

TI Cropping intensity effects on physical properties of a no-till silt loam SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID CENTRAL GREAT-PLAINS; CHEMICAL-PROPERTIES; SYSTEM INFLUENCES; SOIL; MANAGEMENT; ROTATIONS; GROWTH AB No-till cropping systems in the semiarid West have the potential to improve soil physical properties by increasing cropping intensity and crop diversity. An investigation at Akron, CO, compared soil conditions in winter wheat (Triticum aestivum L.)-summer fallow (WF) plots with soil conditions in wheat-corn (Zea mays L.)-fallow (WCF), wheat-corn-sunflower (Helianthus annus L.)-fallow (WCSF), wheat-corn-millet (Panicum miliaceum L.) (WCM), and a perennial grass/legume mix. The study began in 1990. Bulk density, pore size distribution, and saturated hydraulic conductivity were measured 7, 11, and 15 yr after inception. Bulk density in the grass plots decreased from 1.39 to 1.25 Mg m(-3) in 15 yr. Bulk density in the annually cropped plots decreased from 1.38 to 1.30 Mg m(-3) during the same time period. The pore size distribution became more uniform among the cropped treatments 15 yr after the start of the experiment. Saturated hydraulic conductivity increased in the grass plots from 27 mm h(-1) to 98 mm h(-1) in 15 yr. Saturated hydraulic conductivity in the annually cropped plots increased from about 14 to about 35 mm h-1 during the same period. The results from this study show that improving soil physical properties by cropping system alone may take many years. Perennial vegetation may be more effective than annually cropped systems at improving soil physical conditions because of less surface compaction from planting operations and the apparent ability of perennial root systems to create a more stable, continuous pore network.

Cesar TI Simulating field-scale soil organic carbon dynamics using EPIC SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID RADIATION USE EFFICIENCY; LONG-TERM EXPERIMENTS; SENSITIVITY ANALYSIS; MODEL CALIBRATION; UNCERTAINTY; LANDSCAPE; EROSION; PRODUCTIVITY; MANAGEMENT AB Simulation models integrate our knowledge of soil organic C (SOC) dynamics and are useful tools for evaluating impacts of crop management on soil C sequestration; yet, they require local calibration. Our objectives were to calibrate the Environmental Policy Integrated Climate (EPIC) model, and evaluate its performance for simulating SOC fractions as affected by soil landscape and management. An automated parameter optimization procedure was used to calibrate the model for a site-specific experiment in the Coastal Plain of central Alabama. The ability of EPIC to predict corn (Zea mays L.) and cotton (Gossypium hirsutum L.) yields and SOC dynamics on different soil landscape positions (summit, sideslope, and drainageway) during the initial period of conservation tillage adoption (5 yr) was evaluated using regression and mean squared deviations. Simulated yield explained 88% of measured yield variation, with the greatest disagreement on the sideslope position and the greatest agreement in the drainageway. Simulations explained approximately 1, 34, and 40% of the total variation in microbial biomass C (MBC), particulate organic C (POC), and total organic C (TOC), respectively. The lowest errors in TOC simulations (0-20 cm) were found on the sideslope and summit. We conclude that the automated parameterization was generally successful, although further work is needed to refine the MBC and POC fractions, and to improve EPIC predictions of SOC dynamics with depth. Overall, EPIC was sensitive to spatial differences in C fractions that resulted from differing soil landscape positions. The model needs additional refinement for accurate simulations of field-scale SOC dynamics affected by short-term management decisions.

Mark TI Dairy manure type, application rate, and frequency impact plants and soils SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID NITROGEN AVAILABILITY; CATTLE MANURE; PHOSPHORUS; FATE; MINERALIZATION; EFFICIENCY; PROTEIN; FARMS; YIELD; COWS AB The impacts of dairy rations on manure chemistry, manure N mineralization in soils, and crop N uptake have been evaluated after single manure applications. No information is available on these impacts when manure is applied to soils at different rates and frequencies. Manure from lactating dairy cows (Bos taurus) fed three diets differing in crude protein (CP) content were applied to a Plano (fine-silty, mixed, superactive, mesic Typic Argiudolls) and a Rosholt (coarse-loamy, mixed, superactive, frigid Haplic Glossudalfs) sod at two application rates (225 or 450 kg total N ha(-1)) and three application frequencies (once, twice, or thrice). Oat (Avena sativa L.), sorghum [Sorghum bicolor (L.) Moench] and sorghum ratoon were grown in succession during a 170-d period. Plant responses to manure from different CP diets were much less than responses due to soil type and manure application rate and frequency. Manure N uptake efficiency by plants was greatest for manure derived from a low-CP diet than manure derived from either the medium- or high-CP diets. Manure application rate and frequency increased NO3 levels in oat and sorghum shoots, which if used as forage could have detrimental impacts on dairy cow health. No significant differences were measured in secondcrop (sorghum) yield or N uptake due to a previous manure application at either N application rate. Third-crop (sorghum ratoon) yield and N uptake were significantly increased, however, due to previous manure applications, but only in pots that received two manure applications at the high rate. Longer term, repeated applications of dairy manure derived from different diets at lower rates could provide more pronounced impacts on plants and soils than those observed during this relatively short-term greenhouse study.

Our objectives were to quantify N capture and changes in soil NO3-N levels in response to N fertilization of triticale grown following either silage corn (Zea mays L.) or soybean [Glycine max (L.) Merr.]. Field studies were conducted in 2003-2004 and 2004-2005 near Ames and Lewis, IA. Soil samples to a depth of 120 cm were collected after the corn and soybean were harvested and again after growing triticale with four rates of N fertilizer (0, 33, 66, and 99 kg N ha(-1)). Partial N budgets were computed using profile NO3-N before triticale planting, N fertilizer applications, plant uptake, and profile NO3-N after triticale harvest. Nitrogen capture by triticale at physiological maturity was 44 to 93 kg N hal when no N was applied and was as high as 164 kg N hat with addition of 99 kg N ha-1. Growing winter triticale reduced profile NO3-N by an average of 33 to 53 kg ha-1 at Ames and 46 to 53 kg ha(-1) at Lewis. Winter triticale dry matter and grain yields were maximized while simultaneously capturing and efficiently utilizing soil N left from previous silage corn and soybean crops.

In Exp. 3, a miniflume was used to determine how a 5-mm-thick, XPAM-treated (0-5 g kg(-1)) sod layer at the inflow end of the "minifurrow" influenced water distribution. The 2 1 -h seepage rates of all soils except the loamy sand decreased curvilinearly with increasing XPAM rate, with maximum reductions of 87 to 94% for 5 and 10 g kg(-1), XPAM rates, relative to controls. The <300-mu m-diam. XPAM granules were significantly more effective than the coarser grained XPAM for reducing seepage, and reducing the thickness of the treated sod layer from 71 to 24 mm had no significant effect on the seepage reduction obtained with YPAM. The 5 g kg(-1) XPAM treatment applied to inflowend miniflume sods significantly decreased the "furrow-stread" advance period and reversed the infiltration patterns observed in miniflumes, relative to controls. These XPAM treatments could potentially be used to increase the uniformity of furrow water applications and reduce seepage from unlined irrigation ponds and canals.

TI Digital elevation accuracy and grid cell size: Effects on estimated terrain attributes SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID SOIL-WATER CONTENT; SPATIAL VARIABILITY; TOPOGRAPHIC MAPS; GRAIN-YIELD; MODEL; SLOPE; PREDICTION; RESOLUTION; LANDSCAPE; MOISTURE AB Terrain attributes are commonly used to explain the spatial variability of agronomic, pedologic, and hydrologic variables. The terrain attributes studied here (elevation, slope, aspect, and curvature) are estimated readily from digital elevation models (DEMs), but questions remain about how the accuracy and sample spacing of the elevation data affect the estimated attributes. The main objective of this study was to quantify differences in each terrain attribute due to factors affecting DEM accuracy and grid cell size. Three data sources were compared: (i) real-time kinematic global positioning system (RTKGPS); (ii) satellite-differentially corrected global positioning system (DGPS); and (iii) U.S. Geological Survey (USGS) 30-m DEMs. The GPS data from three undulating agricultural fields in northeastern Colorado were interpolated onto 5-, 10-, 20-, and 30-m grid DEMs. The DGPS and USGS DEMs produced similar elevation differences relative to RTKGPS DEMs, but elevation differences in USGS DEMs were more spatially correlated. Estimates of curvature were highly sensitive to DEM differences and the sensitivity of slope, aspect, and curvature estimates decreased as grid cell size increased. The impacts of DEM accuracy and grid cell size were investigated using correlations between wheat (Triticum aestivum L.) grain yields mid estimated terrain attributes. The highest correlation coefficients were obtained using RTKGPS data, and decreasing the sample spacing or grid cell size below 30 m did not consistently improve the correlations. These analyses on agricultural lands indicate the importance of accurate elevation data for detailed terra-in analyses on grid cell sizes of 30 in or less.

In Verrill and Johnson [2007. Confidence bounds and hypothesis tests for normal distribution coefficients of variation. USDA Forest Products Laboratory Research Paper FPL-RP-638], we use this result to establish that estimators based on Newton steps from root n-consistent estimators may be used in place of efficient solutions of the likelihood equations in likelihood ratio, Wald, and Rao tests. Taking a quadratic mean differentiability approach rather than our Cramer condition approach, Lehmann and Romano [2005. Testing Statistical Hypotheses, third ed. Springer, New York] have outlined proofs of similar results. However, their Newton step estimator results actually rely on unstated assumptions about Cramer conditions.

These findings violate core assumptions underlying DNA sequence data obtained via polymerase chain reaction (PCR) amplification for use in molecular systematics investigations. Undetected intra-individual variation of this sort can confound phylogenetic analyses at a range of taxonomic levels. The use of a DNA extraction protocol designed to enrich mitochondrial DNA as well as an initial long PCR of approximately 40% of the grasshopper mitochondrial genome failed to control for the presence of paralogous mitochondrial DNA-like sequences within individuals. These findings constitute the first demonstration of intra-individual heterogeneity in mitochondrial DNA-like sequences in the grasshopper subfamily, Melanoplinae, and only the second report of intra-individual variation in nuclear ITS ribosomal DNA sequences in grasshoppers. The fact that intra-individual variation was detected in two independent DNA marker sets in the same organism strengthens the notion that the orthology of PCR-derived DNA sequences should be examined thoroughly prior to their use in molecular phylogenetic analyses or as DNA barcodes.

TI Modeling biased fineness and maturity results SO TEXTILE RESEARCH JOURNAL LA English DT Article DE cotton; fineness; maturity; bias; modeling; Lord's model AB In an earlier paper, our classical models study included simulations to explain the variability in coefficients of determination (R-2) between fineness and maturity, micronaire and fineness, and micronaire and maturity of cotton. Subsequently, we emphasized the derivation and testing of three diagnostic models to enhance the R-2 and provide information about the analytical quality (accuracy) of the results. In this paper, the theory of biased fineness and maturity measures is introduced and effects on the relationships with micronaire are simulated. Error functions based on Lord's micronaire model are derived to express biased results relative to the unbiased values. The simulations include three case studies in order of increasing complexity: bias varies linearly with micronaire, bias is nonlinear with micronaire, and random error is added to the bias. Classical and diagnostic model plots of the simulated unbiased and biased data are presented in detail to readily determine differences in the relationships.

It was developed in an F2 segregating population of 143 individuals obtained by crossing double haploid plants of broccoli "Early-Big" and cauliflower "An-Nan Early". These markers are randomly distributed throughout the map, which includes a total of 1,062 genomic SRAP markers, 155 cDNA SRAP markers, 26 SSR markers, 3 broccoli BAC end sequences and 11 known Brassica genes: BoGSL-ALK, BoGSL-ELONG, BoGSL-PROa, BoGSL-PROb, BoCS-lyase, BoGS-OH, BoCYP79F1, BoS-GT (glucosinolate pathway), BoDM1 (resistance to downy mildew), BoCALa, BoAP1a (inflorescence architecture). BoDM1 and BoGSL-ELONG are linked on LG 2 at 0.8 cM, making it possible to use the glucosinolate gene as a marker for the disease resistance gene. By QTL analysis, we found three segments involved in curd formation in cauliflower. The map was aligned to the C genome linkage groups and chromosomes of B. oleracea and B. napus, and anchored to the physical map of A. thaliana. This map adds over 1,000 new markers to Brassica molecular tools. C1 Univ Kentucky, Dept Plant & Soil Sci, Lexington, KY 40546 USA. Univ Manitoba, Dept Plant Sci, Winnipeg, MB R3T 2N2, Canada.

The accuracy of the equation was demonstrated with a 0.1 M sucrose solution frozen at temperatures from -0.5 to -6 degrees C in an isothermal calorimeter. Empirical measurements using latent heat as a measure of the amount of water frozen were within 1% of the expected values calculated from the equation. The extent to which percentages of water freezing in oat crown tissue at varying temperatures follows the expected freezing curve indicates how closely the system follows colligative freezing processes. The freezing curve for non-acclimated crowns followed a colligative freezing pattern more closely than did the curve for crowns from cold-acclimated plants. This suggests that water in crowns from non-acclimated plants may remain unfrozen primarily by colligative means while other mechanisms of keeping water unfrozen are important in cold-acclimated crowns. This may help explain contradictory results of studies that attempt to correlate carbohydrate concentrations with freezing tolerance. Published by Elsevier B.V. C1 USDA, Raleigh, NC 27695 USA.

TI Biological stress response terminology: Integrating the concepts of adaptive response and preconditioning stress within a hormetic dose-response framework SO TOXICOLOGY AND APPLIED PHARMACOLOGY LA English DT Article ID RADIATION HORMESIS; HISTORICAL FOUNDATIONS; ALCOHOL-CONSUMPTION; ESCHERICHIA-COLI; DNA-REPAIR; HYPOTHESIS; MORTALITY AB Many biological subdisciplines that regularly assess dose-response relationships have identified an evolutionarily conserved process in which a low dose of a stressful stimulus activates an adaptive response that increases the resistance of the cell or organism to a moderate to severe level of stress. Due to a lack of frequent interaction among scientists in these many areas, there has emerged a broad range of terms that describe such dose-response relationships. This situation has become problematic because the different terms describe a family of similar biological responses (e.g., adaptive response, preconditioning, hormesis), adversely affecting interdisciplinary communication, and possibly even obscuring generalizable features and central biological concepts. With support from scientists in a broad range of disciplines, this article offers a set of recommendations we believe can achieve greater conceptual harmony in dose-response terminology, as well as better understanding and communication across the broad spectrum of biological disciplines.

TI Invasion by nonnative brook trout in panther creek, Idaho: Roles of local habitat quality, biotic resistance, and connectivity to source habitats SO TRANSACTIONS OF THE AMERICAN FISHERIES SOCIETY LA English DT Article ID NATIVE CUTTHROAT TROUT; WESTERN NORTH-AMERICA; SALVELINUS-FONTINALIS; RAINBOW-TROUT; STREAM FISHES; POTENTIAL IMPACTS; WATER TEMPERATURE; SALMO-GAIRDNERI; FRESH-WATER; INCUBATION AB Theoretical models and empirical evidence suggest that the invasion of normative species in freshwaters is facilitated through the interaction of three factors: habitat quality, biotic resistance, and connectivity. We measured variables that represented each factor to determine which were associated with the occurrence of normative brook trout Salvelinus fontinalis in Panther Creek, a tributary to the Salmon River, Idaho. Habitat variables included measures of summer and winter temperature, instream cover, and channel size. The abundance of native rainbow trout Oncorhynchus mykiss within sampled sites was used as a measure of biotic resistance. We also considered the connectivity of sample sites to unconfined valley bottoms, which were considered habitats that may serve as sources for the spread of established populations of brook trout. We analyzed the occurrence of small (< 150-mm [fork length]) and large (>= 150-mm) brook trout separately, assuming that the former represents an established invasion while accounting for the higher potential mobility of the latter. The occurrence of small brook trout was strongly associated with the proximity of sites to large, unconstrained valley bottoms, providing evidence that such habitats may serve as sources for the spread of brook trout invasion. Within sites, winter degree-days and maximum summer temperature were positively associated with the occurrence of small brook trout. The occurrence of large brook trout was not related to any of the variables considered, perhaps due to the difficulty of linking site-specific habitat factors to larger and more mobile individuals. The abundance of rainbow trout was not conclusively associated with the occurrence of either small or large brook trout, providing little support for the role of biotic resistance. Overall, our results suggest that source connectivity and local habitat characteristics, but not biotic resistance, influence the establishment and spread of normative brook trout populations. Further work is needed to confirm that the patterns observed here are relevant to other localities where brook trout have invaded and to understand the mechanisms contributing to the invasion process.

TI Genetic investigation of natural hybridization between rainbow and coastal cutthroat trout in the copper river Delta, Alaska SO TRANSACTIONS OF THE AMERICAN FISHERIES SOCIETY LA English DT Review ID ONCORHYNCHUS-CLARKI-LEWISI; ENDANGERED SPECIES ACT; INTROGRESSIVE HYBRIDIZATION; POPULATION-STRUCTURE; MICROSATELLITE LOCI; ATLANTIC SALMON; MITOCHONDRIAL-DNA; HYBRID ZONES; LIFE-HISTORY; ASYMMETRIC HYBRIDIZATION AB Molecular genetic methods were used to quantify natural hybridization between rainbow trout Oncorhynchus inykiss or steelhead (anadromous rainbow trout) and coastal cutthroat trout O. clarkii clarkii collected in the Copper River delta, Southeast Alaska. Eleven locations were sampled to determine the extent of hybridization and the distribution of hybrids. Four diagnostic nuclear microsatellite loci and four speciesspecific simple sequence repeat markers were used in combination with restriction fragment length polymorphism analyses of NADH dehydrogenase 5/6 (ND5/6) mitochondrial DNA (mtDNA) to investigate the genetic structure of trout from both species and identify putative interspecific hybrids. Hybrids were found in 7 of the I I streams sampled in the Copper River delta, the extent of hybridization across all streams varying from 0% to 58%. Hybrid trout distribution appeared to be nonrandom, most individuals of mixed taxonomic ancestry being detected in streams containing rainbow trout rather than in streams containing coastal cutthroat trout. Genotypic disequilibrium was observed among microsatellite loci in populations with high levels of hybridization. We found no significant correlation between unique stream channel process groups and the number of hybrid fish sampled. Eighty-eight percent of fish identified as first-generation hybrids (F(1)) in two populations contained coastal cutthroat trout mtDNA, suggesting directionality in hybridization. However, dominance of coastal cutthroat trout mtDNA was not observed at a third location containing F(1) hybrids, indicating that interspecific mating behavior varied among locations. Backcrossed individuals were found in drainages lacking F(1) hybrids and in populations previously thought to contain a single species. The extent and distribution of backcrossed individuals suggested that at least some hybrids are reproductively viable and backcrossed hybrid offspring move throughout the system.

TI Validation of endoscopy for determination of maturity in small salmonids and sex of mature individuals SO TRANSACTIONS OF THE AMERICAN FISHERIES SOCIETY LA English DT Article ID LARGEMOUTH BASS; CUTTHROAT TROUT; ATLANTIC SALMON; TRANSMITTERS; ULTRASOUND; STURGEON; FISH AB Fish maturity status, sex ratio, and age and size at first maturity are important parameters in population assessments and life history studies. In most empirical studies of these variables, fish are sacrificed and dissected to obtain data. However, maturity status and the sex of mature individuals can be determined by inserting an endoscope through a small incision in the body cavity wall and viewing the gonads. The objective of this study was to evaluate endoscopy in a field setting for gonadal assessment of streamresident forms of salmonids that mature at small sizes. Ninetyone brook trout Salvelinus fontinalis (60-210 mm fork length [FL]) were obtained via electrofishing and anesthetized. Maturity status and sex of mature individuals were determined with an endoscope. After recovery, individuals were euthanized with anesthetic and were dissected to validate the endoscopic classification. Endoscopy correctly determined the maturity status and sex of mature individuals for 96% of the brook trout; the highest accuracy was observed for the smallest (60-70 mm FL) and largest (>140 mm FL) individuals examined. In the misclassifications, visceral fat hampered visibility and was mistaken for mature testes. Immediate postprocedure mortality was 3.3% and was limited to individuals smaller than 70 turn FL. Endoscopy is a useful technique that can be used in field settings to assess maturity status and sex of mature fish with a low rate of immediate mortality.

TI In-row subsoiling and controlled traffic effects on coastal plain soils SO TRANSACTIONS OF THE ASABE LA English DT Article DE cone index; soil compaction; subsoiling ID CONSERVATION TILLAGE; STRENGTH; COTTON; SYSTEM; YIELD AB Soil compaction is an acute problem in the southeastern U.S., requiring periodic subsoiling to alleviate densely compacted soils. Controlling vehicle traffic is one method that has been recommended for reducing the negative effects of vehicle traffic. The objective of this study was to determine the differences in soil bulk density and cone index resulting from the interactions of surface tillage, subsoiling, and controlled traffic in a long-term corn-soybean cropping system experiment in a Coastal Plain soil in the southeastern U.S. Traffic or no-traffic treatments were accomplished using an experimental wide-frame tractive vehicle (WFTV), which enabled operations without traffic on 6.1 m wide growing zones. Subsoiling treatments included no subsoiling, annual in-row subsoiling, and initial one-time subsoiling on 25 cm centers to completely disrupt the soil to the 40 cm depth. Surface tillage treatments were no-tillage or disking and field cultivation. Soil measurements were taken after the treatments were imposed for five years. Bulk density and cone index measurements were taken at three positions in the plots: the trafficked row middle, the in-row position, and the non - trafficked row middle. Four significant conclusions from this study can be drawn: (1) vehicle traffic increased soil bulk density nearest the surface in all row positions, with the greatest increases occurring directly in the trafficked row position where equipment traffic was applied; (2) no-tillage caused significantly increased bulk density values near the soil surface in all three row positions; (3) annual in-row subsoiling effectively relieved soil compaction, while the initial complete disruption subsoiling treatment had similar bulk density and cone index values as the no-subsoiling treatment; and (4) in-row subsoiling also loosened the non-trafficked row middle, thereby compensating for the negative effects of vehicle traffic in the trafficked row middle. Consequently, crop yields were increased by in-row subsoiling but were not affected by vehicle traffic. Therefore, the influence of annual in-row subsoiling was greater on crop productivity for Coastal Plain soils than was the influence of controlled traffic.

TI AGDISP sensitivity to crop canopy characterization SO TRANSACTIONS OF THE ASABE LA English DT Article; Proceedings Paper CT ASAE Annual Meeting CY 2005 CL Tampa, FL SP ASAE DE aerial application; AGDISP; sampling; spray deposition; spray drift ID AERIAL APPLICATIONS; SPRAY DRIFT; AIRCRAFT; PARAMETERS; DISPERSION; HEIGHT; SIZE AB As computer-based decision and modeling systems become increasingly integrated into agriculture, it is important that users understand the effects that various inputs have on these systems. The objective of the work presented here is to quantify the effects that different crop canopy characteristics, such as height and canopy closure, have on aerially applied spray deposition and downwind movement and compare these results to the predictions of spray movement and deposition by the AGDISP computer model. Six trials were conducted in cotton fields ranging from bare ground up to 1 m in height and canopy closure ranging from 0% to 100%. Horizontal deposition measurements were used to verify that each of the applications made during each of the trials produced similar levels of deposition. Monofilament strings were placed at four sampling heights (1, 2,4, and 6 m) above the canopy at a distance of 50 m from the downwind edge of the spray swath to measure the airborne droplets at this distance. The vertical deposition values at 50 m for crop heights between 0.3 and 0.8 m were comparable between the field-collected and AGDISP-predicted data. The AGDISP model (version 8.08) overpredicted by a factor of 2 the levels of deposition at I m for the trials conducted with crop canopy height of 0 or 1 m as compared to field measurements; however, at 4 and 6 m above the ground, AGDISP and the field data agreed well. Users of AGDISP should be encouraged by the accuracy of the model but are cautioned when using the model with canopies that are more than 80% closed. C1 USDA ARS, College Stn, TX 77845 USA.

Characterization requires determining two parameters that define individual material particles: equivalent spherical diameter (ESD) and particle sphericity. ESD is found by weighing a known number of particles with a microbalance and then determining particle volume. Particle sphericity is found by a drop test, which measures the time of travel between two points when the individual particles are falling at their terminal velocities. An experimentally determined nonspherical drag law for dry particles is then used to determine sphericity. ESD and particle sphericity modify the particle drag coefficient that defines the behavior of the dry material when released from aircraft. This article reviews these details and demonstrates the complications of describing dry materials, specifically for the aerial application model AGDISP. C1 Continuum Dynam Inc, Ewing, NJ 08618 USA.

TI Catch-can performance under a line-source sprinkler SO TRANSACTIONS OF THE ASABE LA English DT Article DE catch-can; evaporation; line-source sprinkler; sprinkler irrigation ID IRRIGATION GRADIENT; CROP PRODUCTION; CULTIVARS; NITROGEN AB A line-source sprinkler configuration provides a linearly decreasing irrigation application rate perpendicular to the sprinkler line and has been utilized to study crop response to variable irrigation amounts. The effect on measured irrigation application depths from using various types of catch-cans in those studies is not known. Derived relationships between crop yield and applied water is dependent on the accuracy of measured catch-can water volumes. The purpose of this study was to evaluate catch-can characteristic effects on measurement of sprinkler irrigation depths in a line source. This was accomplished by evaluating six types of catch-cans: (1) 83 mm diameter polypropylene separatory funnel (with evaporation-suppressing oil), (2) 82 mm diameter PVC reducer can (with evaporation-suppressing oil), (3) 151 mm diameter metal can, (4) 64 X 59 mm wedge rain gauge, (5) 146 nun white plastic bucket, and (6) 100 nun diameter clear plastic funnel rain gauge. The cans were placed at five application rate conditions (2.8, 5.5, 8.7, 12.6, and 14.8 mm/h). Cumulative catch depths differed among the catch-can types. However, only the metal can and white bucket cumulative application depths at the lowest application rate were statistically different from those of the control (separatory funnel). Catch-cans with a larger diameter opening exhibited less variation in catch depths. Measured evaporation of standing water from catch-cans varied from 0.04 mm/h (funnel rain gauge) to 1.81 mm/h (separatory funnel without evaporation-suppressing oil). Water applied to a bucket's sidewall evaporated at a higher rate than standing water. Inaccuracy of application depth measurement may occur at low application rates even when catch-cans meet the ASAE Standard. The relatively good performance of the funnel rain gauge and catch-cans with evaporation-suppressing oil (and subsequently less depth than the ASAE Standard requires) suggests that it may be appropriate to re-evaluate the standard to consider such devices.

TI Soil and water assessment tool hydrologic and water quality evaluation of poultry litter application to small-scale subwatersheds in Texas SO TRANSACTIONS OF THE ASABE LA English DT Article DE hydrologic modeling; nutrients; poultry litter; sediment; subwatershed; SWAT ID AGRICULTURAL PHOSPHORUS; MODEL; RUNOFF; MANAGEMENT; AUTOCALIBRATION; FERTILIZATION; VALIDATION; MANURE; POINT; BASIN AB The application of poultry litter to agricultural land has become a topic of interest for policy makers due to public concern about its effects on water quality. The Soil and Water Assessment Tool (SWAT) version 2005 is designed to assess nonpoint and point sources of pollution. In this study, six subwatersheds in Texas (HUC-8; 12070101) are used to evaluate the model's ability to simulate water quality at a small scale. Each of these subwatersheds randomly received poultry litter rates of 0.0 to 13.4 Mg ha(-1). Monthly and daily data from 2002 were used for calibration purposes, while 2000, 2001, 2003, and 2004 were used for validation. The SCS runoff curve number for moisture condition H (CN2) and the soil evaporation compensation factor (ESCO) parameters were found to be more sensitive than the surface runoff lag time (SURLAG) and initial soil water content expressed as a fraction of field capacity (FFCB). The monthly and daily runoff model simulations for the six subwatersheds resulted in calibration Nash-Sutcliffe efficiency (NSE) values of 0.59 and 0.53 and validation NSE values 0.82 and 0.80, respectively. The monthly and daily R-2 runoff values for the six subwatersheds resulted in calibration values of at least 0.60 and 0.53 and validation R-2 values of 0.86 and 0.81, respectively. The observed trends included SWAT's overestimation of runoff in the dry periods and underestimation in the wet periods. The monthly NSE and R-2 values for sediment and nutrient losses were generally above 0.4 and 0.5, respectively. Paired t-tests for the monthly manually adjusted parameter simulation of sediment, organic N and P, NO3 -N, and soluble P for the 2000-2004 period losses showed that their respective SWAT means were not significantly different from the measured values (a = 0. 05), except for NO3 -N losses for the Y10 subwatershed (p-value 0.042). The control subwatershed's measured and simulated water quality results were significantly different (a = 0.05) from the treated subwatersheds, most likely due to the amount of inorganic N present. Almost all of the subwatersheds that had poultry litter applied resulted in higher sediment, organic N, organic P, and soluble P losses than the control subwatershed upon averaging the monthly validation values. High NO3 -N losses may have been a function of poultry litter and commercial fertilizers being applied before a large rainfall event occurred. The subwatersheds that received smaller amounts of commercial fertilizer and/or poultry litter lost more sediment, organic N, and organic P than the subwatersheds that received the higher litter and/or fertilizer treatments. Overall, the SWAT simulated the hydrology and the water quality constituents at the subwatershed scale more adequately when all of the data were used to simulate the model, as evidenced by statistical measures.

SWAT has gained international acceptance as a robust interdisciplinary watershed modeling tool as evidenced by international SWAT conferences, hundreds of SWAT-related papers presented at numerous other scientific meetings, and dozens of articles published in peer-reviewed journals. The model has also been adopted aspart of the U.S. Environmental Protection Agency (USEPA) Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) software package and is being used by many U.S. federal and state agencies, including the USDA within the Conservation Effects Assessment Project (CEAP). At present, over 250 peer-reviewed published articles have been identified that report SWAT applications, reviews of SWAT components, or other research that includes SWAT Many of these peer-reviewed articles are summarized here according to relevant application categories such as streamflow calibration and related hydrologic analyses, climate change impacts on hydrology, pollutant load assessments, comparisons with other models, and sensitivity analyses and calibration techniques.

To better assess the fate and transport of nutrients, such as NO3 -N, the tile drain and pothole components of SWAT (Soil and Water Assessment Tool) were enhanced and modified in the previous component of this study. In this study, the environmental and economic impacts of various best management practice (BMP) scenarios often adopted by local farmers to reduce sediment and nutrient loadings (in particular NO3-N) were evaluated using the modified SWAT (SWAT-M) and FEM (Farm-level Economic Model) models. Measured values of water quality indicators from the Walnut Creek watershed (WCW) located in central Iowa were used to verify the capability of SWAT-M to predict the impact of late-spring nitrate test (LSNT) and rye cover crop management on N03 -N reduction at the subbasin level. The results obtained from SWAT-M simulation results, similar to field measurement data, indicated a 25% reduction in N03 -N under the LSNT scenario. FEM results indicated a corresponding increased annual cost of $6/ha across all farms in the watershed. Simulation of other scenarios, including winter cover cropping and a combination of LSNT and cover cropping at different adoption rates within WCW, resulted in a progressive reduction in sediment and nutrient losses as adoption rates increased. Use of the rye cover crop added about $25/ha to $35/ha to the annual cost of the average farm, indicating that some cost-share support may be necessary to encourage farmers to use winter cover crops.

In a field near Story City, Iowa, ten years (1996-2005) of measured data were collected from plots receiving low, medium, and high (57-67, 114-135, and 172-202 kg N ha(-1)) nitrogen (N) fertilizer application rates during corn (Zea mays L.) years. Using these data, the Root Zone Water Quality Model linked with the CERES and CROPGRO plant growth models (RZWQM-DSSAT) was evaluated for simulating the various N application rates to corn. The evaluated model was then used with a sequence of historical weather data (1961-2005) to quantify the long-term effects of different N rates on corn yield and nitrogen dynamics for this agricultural system. Simulated and measured dry-weight corn yields, averaged over plots and years, were 7452 and 7343 kg ha(-1) for the low N rate, 8982 and 9224 kg ha(-1) for the medium N rate, and 9143 and 9484 kg ha(-1) for the high N rate, respectively. Simulated and measured flow-weighted average nitrate concentrations (FWANC) in drainage water were 10.6 and 10.3 mg L-1 for the low N rate, 13.4 and 13.2 mg L-1 for the medium N rate, and 18.0 and 19.1 mg L-1 for the high N rate, respectively. The simulated N rate for optimum corn yield over the long term was between 100 and 150 kg N ha(-1). Currently, the owner-operator of the farm applies 180 kg N ha(-1) to corn in nearby production fields. Reducing long-term N rates from 180 to 130 kg N ha(-1) corresponded to an 18% simulated long-term reduction in N mass lost to water resources. Median annual FWANC in subsurface drainage water decreased from 19.5 to 16.4 mg N L-1 with this change in management. Current goals for diminishing the hypoxic zone in the Gulf of Mexico call for N loss reductions of 30% and greater. Thus, long-term simulations suggest that at least half of this N loss reduction goal could be met by reducing N application rates to the production optimum. However, additional changes in management will be necessary to completely satisfy N loss reduction goals while maintaining acceptable crop production for the soil and meteorological conditions of this study. The results suggest that after calibration and thorough testing, RZWQM-DSSAT can be used to quantify the long-term effects of different N application rates on corn production and subsurface drainage FWANC in Iowa.

Head rice yield was more sensitive to changes in milling conditions than total rice yield. It decreased by 4.6 percentage points when milling weight was increased from 2.72 to 6.36 kg. Milling weight and milling duration had more influence on head rice yield than polishing weight and duration. For both milling and polishing, using lower weights for a longer duration could increase head rice yield without changing the whiteness compared to the standard procedures of the USDA Federal Grain Inspection Service. The total lipid content of milled rice, measured using a near-infrared (NIR) method, correlated well with the whiteness index. This indicates that the NIR method could be used as an alternative to the whiteness index for measuring the degree of milling. Over-milling significantly decreased head rice yield with little improvement in whiteness. The milling quality of M202 can be predicted by using the developed non-linear regression models when the milling and polishing conditions are known.

TI Improved hyperspectral imaging system for fecal detection on poultry carcasses SO TRANSACTIONS OF THE ASABE LA English DT Article DE contaminants; fecal; food safety; ingesta; pathogen; poultry ID CONTAMINATION; SAFETY; SPECTROSCOPY; REFLECTANCE; INSPECTION; INGESTA AB The USDA Agricultural Research Service (ARS) has developed a hyperspectral imaging system to detect fecal contaminants on poultry carcasses. The system measures the intensity of reflected light energy from about 400 nm to 1000 nm and has been used as a research tool to identify key wavelengths for detecting contaminants. Selected wavelengths are to be used in a real-time multispectral system for contaminant detection. The ARS has reported that the ratio of reflectance images at 565 nm and 517 nm was able to identify fecal contaminants. However, this ratio alone also misclassified numerous non-fecal carcass features (false positives). Recent modifications to the system, including improved lighting, a new camera, a new spectrograph, and a new algorithm with an additional wavelength, have increased fecal detection accuracy while reducing the number of false positives. The new system was used to collect hyperspectral data on 56 stationary poultry carcasses. Carcasses were contaminated with both large and small spots of feces from the duodenum, ceca, and colon, and ingesta from the crop. A total of 1030 contaminants were applied to the carcasses. The new system and algorithm correctly identified over 99% of the contaminants with only 25 false positives. About a quarter of the carcasses had at least one false positive pixel.

The global threshold strategy for a band-ratio algorithm has been known to be limited to pixel-basis detection. In an attempt to develop a statistical decision rule for carcass-basis detection from multispectral images, probability density functions of both contaminated and uncontaminated materials were estimated by parametric and non-parametric methods. We found that uncontaminated poultry carcasses could be modeled by a Gaussian distribution, whereas contaminated materials were non-Gaussian. A kernel density estimator was used to analyze the non-Gaussian characteristic of the contaminated materials on a transformed projection axis. A linear mixture of the density functions was introduced to model the observations made on the projection axis. A new detection algorithm was designed using the mixture model and tested for 496 birds (248 dirty and 248 clean birds). A test on the sample birds revealed that the algorithm needed at least 12 contaminant pixels to reach the perfect detection results. The test also showed a false-positive rate of less than 5%.

Model evaluation indicated that sediment losses were adequately estimated compared to observed data for a corn production system in Texas. In a further evaluation, sediment losses simulated for a wide range in cropping systems and tillage practices were similar to those predicted by the current state-of-the art erosion estimation model (WEPP). Total P losses were accurately predicted when manure P was applied at suitable rates of less than 250 kg P ha(-1), but at higher application rates overestimation of P loss was found. Compared to observed data, soluble P loss was underestimated and sediment P loss was overestimated, but this was primarily due to a difference in the differentiation between soluble and sediment P between the modeling and experimental studies. To illustrate the use of the model, IFSM simulations were performed to evaluate the effects of manure handling and tillage systems on P loss from farms in Pennsylvania. For a 100-cow dairy farm, a manure handling strategy that used a 6-month storage and application by injection decreased total P loss by 19% compared to daily surface application, but annual farm net return was decreased by $57/cow. Compared to conventional tillage with a moldboard plow, use of conservation tillage and no-till systems reduced total P loss by 46% and 57%, respectively, with small increases in farm profitability. Reduced tillage increased soluble P loss, suggesting that conservation and no-till systems should be combined with practices such as manure injection to reduce all forms of P loss. The enhanced IFSM containing the soil P model provides a tool for whole-farm analysis of management effects on P loss along with other environmental and economic considerations.

TI Using cross-validation to evaluate CERES-Maize yield simulations within a decision support system for precision agriculture SO TRANSACTIONS OF THE ASABE LA English DT Article; Proceedings Paper CT Annual Meeting of the American-Society-of-Agricultural-and-Biological-Engineers CY NOV 09-12, 2005 CL Univ Wisconsin-Madison, Madison, WI HO Univ Wisconsin-Madison DE corn; crop model; cross-validation; decision support system; precision agriculture; spatial variability; yield ID NITROGEN MANAGEMENT; MEASURED VALUES; SOYBEAN YIELD; MODEL; WATER; CORN; VARIABILITY; GROWTH; STRATEGIES; DRAINAGE AB Crop growth models have recently been implemented to study precision agriculture questions within. the framework of a decision support system (DSS) that automates simulations across management zones. Model calibration in each zone has occurred by automatically optimizing select model parameters to minimize error between measured and simulated yield over multiple growing seasons. However, to date, there have been no efforts to evaluate model simulations within the DSS. In this work, a model evaluation procedure based on leave-one-out cross-validation was developed to explore several issues associated with the implementation of CERES-Maize within the DSS. Five growing seasons of measured yield data from a central Iowa cornfield were available for cross-validation. Two strategies were used to divide the study area into management zones, one based on soil type and the other based on topography. The decision support system was then used to carry out the model calibration and validation simulations as required to complete the cross-validation procedure. Results demonstrated that the model's ability to simulate corn yield improved as more growing seasons were used in the cross-validation. For management zones based on topography, the average root mean squared error of prediction (RMSEP) from cross-validations was 1460 kg ha(-1) when two growing seasons were used and 998 kg ha-1 when five years were used. Model performance was shown to vary spatially based on soil type and topography. Average RMSEP was 1651 kg ha-1 on zones of Nicollet loam, while it was 496 kg ha-1 on zones of Canisteo silty clay loam. Spatial patterns also existed between areas of higher RMSEP and areas where measured spatial yield variability was related to topography. Changes in the mean and variance of optimum parameter sets as more growing seasons were used in cross-validation demonstrated that the optimizer was able to arrive at more stable solutions in some zones as compared to others. Results suggested that cross-validation was an appropriate method for addressing several issues associated with the use of crop growth models within a DSS for precision agriculture.

They are oligoesters obtained by the reaction of fatty acids and/or methyl esters with a double bond. By varying the chemistries of the starting materials and the reaction conditions, estolides of varying chemical structures (e.g., branching), and physical properties (e.g., mol wt, viscosity, pour point, cloud point) are obtained. Estolides have been found to have suitable properties for some lubrication applications. In this work, the effect of estolide physical/chemical variability on film thickness and pressure-viscosity coefficient (pvc) were examined. The results showed that estolides have lower pvc than the non-polar hydrocarbon PAO, but much higher than seed oils (e.g., soybean, jojoba, canola), which are used as feedstock in estolide synthesis. The film thickness and pvc properties of estolides were also found to be dependent on the structure (e.g., home- versus co-oligomer) and purity of the estolide oils.

Two uninoculated calves served as controls. Within 26 months postinoculation (MPI), 12 inoculated calves had lost considerable weight and eventually became recumbent. Of the 12 inoculated calves, 11 (92%) developed clinical signs. Although spongiform encephalopathy (SE) was not observed, abnormal prion protein (Prp(d)) was detected by immunohistochemistry (IHC) and Western blot (WB) in central nervous system tissues. The absence of SE with presence of Prpd has also been observed when other TSE agents (scrapie and CWDmd) were similarly inoculated into cattle. The IHC and WB findings suggest that the diagnostic techniques currently used to confirm BSE would detect CWDwtd in cattle should it occur naturally. Also, the absence of SE and a distinctive IHC pattern of CWDwtd and CWDmd in cattle suggests that it should be possible to distinguish these conditions from other TSEs that have been experimentally transmitted to cattle.

The Left ORF codes for non-structural protein and the Right ORF codes for capsid protein, whereas the role of the Middle ORF is still unknown. Two putative promoters, designated P2 and P61, were detected upstream of the Left ORF and Right ORF, respectively. We evaluated the activities of these two promoters with or without a transcriptional enhancer element via the use of firefly luciferase reporter constructs in insect and fish cells, and in shrimp tail muscle. In insect and fish cells, the P2 promoter was stronger than the P61 promoter. The presence of the SV40 enhancer element negatively affected P2 but not P61 promoter activity in insect cells. However, in fish cells, the SV40 enhancer element dramatically increased the activities of both promoters. In shrimp, there was no significant difference in luciferase expression driven by these two promoters. In shrimp tail muscle, the presence of SV40 enhancer element in the construct had no significant effect on the P2 promoter and a negative effect on the P61 promoter. The IHHNV P2 and P61 promoters were found to be constitutive promoters that can drive gene expression in both invertebrate and vertebrate hosts. (C) 2007 Elsevier B.V. All rights reserved.

Four virus and virus-like agents, two of which are poorly characterized, have been implicated in the disease complex based on symptom development in Rubus indicators. Three novel viruses were identified in a red raspberry plant that caused typical raspberry mosaic symptoms when grafted onto indicators. This communication focuses on one of these viruses, Raspberry mottle virus (RMoV), a new member of the family Closteroviridae. The complete nucleotide sequence of RMoV has been determined and exceeds 17 kilobases encoding 10 genes. The genome organization of RMoV is similar to that of Beet yellows virus, the type member of the Closterovirus genus, and phylogenetic analysis using the polymerase conserved motifs and the beat shock protein 70 homolog revealed a close relationship of RMoV with Strawberry chlorotic fleck associated virus and Citrus tristeza virus, which suggests the possibility of an aphid vector. The virus was detected in symptomatic raspberry plants in production areas in mixed infections with several other viruses, indicating that RMoV may impact raspberry production. (C) 2007 Elsevier B.V.

In order to better understand the factors influencing NH3 emission from agriculture, this research was conducted with four major soils used for potato production: Biscayne Marl Soil (BMS, pH 7.27), and Krome Gravelly Loam (KGL, pH 7.69) from Florida; and Quincy Fine Sand (QFS, pH 6.65), and Warden Silt Loam (WSL, pH 6.46) from Washington. Potassium nitrate (KNO3), ammonium nitrate (NH4NO3), ammonium sulfate ((NH4)(2)SO4) or urea ((NH)(2)CO) sources were evaluated for ammonia volatilization at 75 kg N ha(-1) rate. The soil water regime was maintained at either 20 or 80% of field capacity (FC), and incubated at 11, 20 or 29 degrees C. Results indicated that NH3 volatilization rate at 20% FC was 2 to 3-fold greater than that at 80% FC. The cumulative volatilization loss over 28 days ranged from 0.21% of N applied as NH4NO3 to 25.7% as (NH4)(2)SO4. Results of this study demonstrate that NH3 volatilization was accelerated at the low soil water regime. Moisture quotient (Q) is defined as a ratio of NH3 emission rate at 20% FC to that at 80% FC both at the same temperature. The peak Q values of NH3 volatilization were up to 20.8 for the BMS soil at 20 degrees C, 112.9 for the KGL soil at 29 degrees C, 19.0 for the QFS soil at 20 degrees C, and 74.1 for the WSL soil at 29 degrees C, respectively. Thus, maintaining a suitable soil water regime is important to minimize N-loss via NH3 volatilization and to improve N uptake efficiency and air quality.

In this laboratory study we grew spinach, radish, and perennial ryegrass on sand blends containing 50% waste foundry sand (WFS) to assess the availability of Al, B, Ba, Be, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, Pb, V, and Zn. The WFSs utilized in this study were from aluminum, iron, and steel foundries. Although there were differences in the amounts of metals accumulated by the various plant species, excessive amounts of heavy metals were not taken up, regardless of WFS treatment. In spinach and radish, B, Cu, Fe, Mn and Zn were found to be within or close to the sufficiency range for agronomic crops. In ryegrass cuttings at 27, 57, and 87 days, Cu and Zn were within sufficiency ranges, but plants were Fe deficient and contained elevated concentrations of B, Mn, and Mo. Data from this study will be useful for state regulatory agencies interested in developing beneficial use regulations for WFSs.

TI Coupling of physical and chemical mechanisms of colloid straining in saturated porous media SO WATER RESEARCH LA English DT Article DE colloid; transport; straining; attachment; filtration theory; modeling ID SECONDARY ENERGY MINIMUM; UNFAVORABLE DEPOSITION CONDITIONS; TO-GRAIN CONTACTS; CRYPTOSPORIDIUM OOCYSTS; MICROSPHERE DEPOSITION; DLVO INTERACTIONS; RATE COEFFICIENTS; FILTRATION THEORY; WASTE-WATER; TRANSPORT AB Filtration theory does not include the potential influence of pore structure on colloid removal by straining. Conversely, previous research on straining has not considered the possible influence of chemical interactions. Experimental and theoretical studies were therefore undertaken to explore the coupling of physical and chemical mechanisms of colloid straining under unfavorable attachment conditions (pH = 10). Negatively charged latex microspheres (1.1 and 3 mu m) and quartz sands (360, 240, and 150 mu m) were used in packed column studies that encompassed a range in suspension ionic strengths (6-106 mM) and Darcy water velocities (0.1-0.45 cm min(-1)). Derjaguin-Landau-Verwey-Overbeek (DLVO) calculations and torque analysis suggests that attachment of colloids to the solid-water interface was not a significant mechanism of deposition for the selected experimental conditions. Effluent concentration curves and hyperexponential deposition profiles were strongly dependent on the solution chemistry, the system hydrodynamics, and the colloid and collector grain size, with greater deposition occurring for increasing ionic strength, lower flow rates, and larger ratios of the colloid to the median grain diameter. Increasing the solution ionic strength is believed to increase the force and number of colloids in the secondary minimum of the DLVO interaction energy profile. These weakly associated colloids can be funneled to small regions of the pore space formed adjacent to grain-grain junctions. For select systems, the ionic strength of the eluant solution was decreased to 6 mM following the recovery of the effluent concentration curve. In this case, only a small portion of the deposited colloids was recovered in the effluent and the majority was still retained in the sand. These observations suggest that the extent of colloid removal by straining is strongly coupled to solution chemistry. (C) 2007 Elsevier Ltd. All rights reserved.

TI Rising atmospheric carbon dioxide and potential impacts on the growth and toxicity of poison ivy (Toxicodendron radicans) SO WEED SCIENCE LA English DT Article DE climate change; carbon dioxide; leaf development; toxicology ID ELEVATED CO2; PLANTS; RESPONSES; LEAVES AB Because of its ability to induce contact dermatitis, the establishment and spread of poison ivy is recognized as a significant public health concern. In the current study, we quantified potential changes in the biomass and urushiol content of poison ivy as a function of incremental changes in global atmospheric carbon dioxide concentration (CO2). We also examined the rate of new leaf development following leaf removal to simulate responses to herbivory as functions of both CO2 and plant size. The experimental CO2 values (300, 400, 500. and 600 mu mol mot(-1)) corresponded approximately to the concentration that existed during the middle of the 20th century, the current concentration and near and long-term projections for this century (2050 and 2090), respectively. Over 250 d, increasing CO2 resulted in significant increases in leaf area, leaf and stem weight, and rhizome length relative to the 300 mu mol mot(-1) baseline with the greatest relative increase occurring from 300 to 400 mu mol mot(-1). There was a nonsignificant (P = 0. 18) increase in urushiol concentration in response to CO2; however, because of the stimulatory effect Of CO2 on leaf biomass, the amount of urushiol produced per plant increased significantly for all CO2 above the 300 mu mol mot(-1) baseline. Significant increases in the rate of leaf development following leaf removal were also observed with increasing CO2. Overall, these data confirm earlier, fieldbased reports on the CO2 sensitivity of poison ivy but emphasize its ability to respond to even small (similar to 100 mu mol mot(-1)) changes in CO2 above the mid-20th century carbon dioxide baseline and suggest that its rate of spread, its ability to recover from herbivory, and its production of urushiol, may be enhanced in a future, higher CO2 environment.

Our specific objective was to determine the influence of clopyralid plus 2,4-D, glyphosat- and fosamine, at different application rates and timings, on richness and diversity of total species, total native species, and total nonnative species within a Russian knapweed-infested plant community. Twenty-eight treatments (3 herbicides by 3 rates by, 3 application timings, and an untreated control) were applied to two sites located along the Missouri River riparian corridor in Montana. Clopyralid plus 2,4-D, glyphosate, and fosamine were applied in June (spring rosette stage of Russian knapweed), July (bud to bloom stage of Russian knapweed), and August (flowering stage of Russian knapweed). Herbicide rates were clopyralid plus 2,4-D at 0.08 (clopyralid) + 0.42 (2,4-D), 0. 13 + 0.67, and 0. IS + 0.92 kg ai ha(-1); glyphosate at 0.6, 1.2, and 1.8 kg ai ha(-1); fosamine at 3.6, 7.2, and 10.8 kg ai ha(-1). Density of each species was recorded during June and August of 2001 and 2002. Species richness and Simpson's Reciprocal Index (I /D) were calculated. By August 2002, only the glyphosate treatment (4. 6 species m- 2) yielded greater total richness over that of the control (3.5 species m- 2). At that time, diversity after applying clopyralid plus 2,4-D remained similar to that of the control (1.4), but glyphosare (2.3) and fosamine (2.0) increased total species diversity. Nonnative grasses and forbs accounted for the increases in richness and diversity. Glyphosate may be appropriate for enhancing ecosystern function and possibly niche occupation to preempt reinvasion by Russian knapweed, but restoring native species seems unlikely using an v of these herbicides alone.

However, little information exists concerning seasonal photosynthesis and carbohydrate partitioning of leafy spurge, although such information would help to elucidate the involvement of sugar in controlling bud dormancy. An outdoor study was conducted over two growing seasons to determine and model seasonal patterns of photosynthesis and aboveground carbohydrate partitioning and their relationship to underground adventitious bud carbohydrate status. Photosynthesis and total nonstructural carbohydrate (TNC) content of aboveground tissues was greatest during vegetative growth. Photosynthesis gradually declined over the growing season, whereas TNC decreased sharply during flowering, followed by a gradual decline between midsummer and autumn. Leaf starch increased dramatically to midsummer before declining sharply throughout late summer and early autumn, whereas sucrose content responded inversely, indicating a mobilization of starch reserves and export of sugars to overwintering belowground sink tissues. Because newly formed underground adventitious buds showed a continuous increase in TNC from midsummer through autumn, export of sugars from aboveground tissues likely contributed to the increase in TNC. These results may facilitate new strategies for biological control of leafy spurge. C1 USDA ARS, N Cent Soil Conservat Res Lab, Morris, MN 56267 USA.

Experimental treatments (winter-spring glyphosate, spring cultivation, fall-spring cultivation, fall cultivation-spring glyphosate) were carried out in a California wine grape vineyard for 3 yr. Cultivation alone was not as effective as glyphosate, based on lower weed biomass in the glyphosate-only treatment in 2 of 3 yr. However, given that two passes with the Clemens cultivator decreased weed biomass relative to one pass, it is possible that additional passes could bring about further reductions. Pairing fall cultivation with glyphosate was as effective at reducing weed biomass as two glyphosate applications in 2 of 3 years, suggesting that substituting a glyphosate application with cultivation may be an effective method of reducing herbicide use in vineyards. Canonical correspondence analysis revealed significant treatment effects on community structure. Weed composition in the spring cultivation treatment was significantly different from that of all other treatments. Based on our findings of high relative abundance of field bindweed and sowthistle species, which are problematic vineyard weeds that grow into the vine canopy and disrupt canopy management practices, it is possible that either the presence of soil disturbance or the absence of herbicides favored these species.

Field studies conducted in 2004 and 2005 evaluated the relationship between the duration of Bengal dayflower interference and peanut yield in an effort to optimize the timing of weed control. In 2004, the critical period of weed control (CpWa necessary to avoid greater than 5% peanut yield loss was between 316 and 607 growing degree days (GDD), which corresponded to an interval between June 8 and July 2. In 2005, the CPWC ranged from 185 to 547 GDD, an interval between May 30 and July 3. Maximum yield loss in 2005 from season-long interference of Bengal dayflower was 51%. In 2004, production of peanut pods was eliminated by interference with Bengal dayflower for the initial 6 wk (495 GDD) of the growing season. Robust Bengal dayflower growth in 2004 shaded the peanut crop, likely intercepting fungicide applications and causing a reduction in peanut yield. Therefore, the competitive effects of Bengal dayflower are likely complicated with the activity of plant pathogens. In spite of higher Bengal dayflower population densities, greater Bengal dayflower growth, and greater peanut yield losses in 2004 than in 2005, the CPWC was a relatively similar 4-wk period that ended during the first week of July, for peanut that was planted in the first week of May.

I hypothesized that simultaneously applying an herbicide and seeding in the fall would produce the highest establishment and growth of desired species. For Russian knapweed, treatments included three seeding rates (zero, low, and high) and two herbicides (with and without clopyralid plus 2,4-D) applied in either the spring (2003) or fall (2004). The seed mixture included pubescent wheatgrass, Siberian wheatgrass, and alfalfa. Grasses were seeded on October 21, 2003 (fall dormant), and April 5, 2004 (spring), using a no-rill rangeland drill. The seeding rates consisted of 3.4, 6.8, and 9.3 (low) or 5.0, 9.0, and 12.3 (high) kg ha(-1) of alfalfa, Siberian wheatgrass, and pubescent wheatgrass, respectively. For green rabbitbrush, treatments included two seeding levels (13.5 kg ha(-1) of Siberian vvheatgrass and nor seeaed) and three herbicides (clopyralid, dicamba, and 2,4-D) and a control applied in July. Clopyralid plus 2,4-D (0.21 plus 1.12 kg ha(-1)) and dicamba at 2.1 kg ha(-1) gave 61 and 66% control of Russian knapweed and green rabbitbrush, respectively. Herbicides interacted with seeding to provide the highest density of seeded species on the Russian knapweed site. These data support the hypothesis that simultaneously applying an herbicide and seeding in the fall would produce the highest establishment and growth of desired species. Conversely, only seeding affected Siberian wheatgrass establishment on the rabbitbrush sites. It may be reasonable to seed Siberian wheatgrass without controlling rabbitbrush if forage production is the primary objective. C1 USDA ARS, Burns, OR 97720 USA.

Fowler, Larry TI Ranking nonindigenous weed species by their potential to invade the United States SO WEED SCIENCE LA English DT Article DE invasive; exotic weeds; invasiveness model; weed risk assessment ID RISK-ASSESSMENT; INVASIVE PLANTS AB Because of the large number of potentially invasive species, and the time required to complete weed risk assessments (WRAs) with the use of the current, mandated system in the United States, species need to be prioritized for assessment and possible listing as Federal Noxious Weeds. Our objective was to rank the potential invasiveness of weedy or pest plant species not yet naturalized in the United States. We created a new model of invasiveness (hereafter the U.S. weed-ranking model) based on scoring factors within four elements: (1) invasiveness potential, or likelihood to exhibit invasive behavior; (2) geographic potential, or habitat suitability; (3) damage potential, or likely impact; and (4) entry potential, or likelihood to be introduced. The ranking score was the product of the four elements. We scored 250 species satisfactorily, from a list of 700 +. We analyzed model sensitivity to scoring factors, and compared results to those from a WRA model for Hawaii. For species not in cultivation in the United States, the top 25 species included a mix of annuals, perennials, sedges, shrubs, and trees. Most had exhibited invasive behavior in at least several other countries. Because of greater entry potential scores, the highest-scoring species were weeds in cultivation. Twenty-nine such species, out of 44 total, had scores greater than the highest scoring species not in cultivation. In comparison to the Hawaii WRA model, correlation and regression analyses indicated that the U.S. weed-ranking model produced similar, but not exact, results. The ranking model differs from other WRAs in the inclusion of entry potential and the use of a multiplicative approach, which better suited our objectives and United States regulations. Two highly ranked species have recently been listed as Federal Noxious Weeds, and we expect most top-tier species to be similarly assessed. C1 Weed Sci Soc Amer, Bristol BS8 4JZ, Avon, England.

No differential absorption of C-14-quinclorac was 14 9 observed between R-BYG and S-BYG, but more C remained in the treated leaf of S-BYG (57% of total absorbed) compared with the R-BYG leaf (34% of total absorbed) at 72 h after treatment (HAT). After 12 HAT, 20 and 15% of the amount absorbed had been translocated basipetally by R-BYG and S-BYG, respectively. At 72 HAT, 27 and 17% of the total absorbed C-14 had been translocated acropetally by R-BYG and S-BYG, respectively. The levels of C-14 above the treated leaf continued to increase throughout the duration of the experiment in R-BYG while levels of C-14 above the 9 C-14 treated leaf in S-BYG remained relatively constant. Seven percent more of the total absorbed was exuded from roots of R-BYG than S-BYG at 72 HAT. Although differential translocation was observed between R-BYG and S-BYG, it is unclear whether this difference is a cause of quinclorac resistance or an effect of some other physiological process. Further research is needed to determine if differential translocation is due to metabolism or other physiological factors. C1 Univ Arkansas, Dept Crop & Soil Environm Sci, Fayetteville, AR 72704 USA.

It also is common in pastures, woodland, and tall forb communities. Bird vetch is expanding along Alaskan roadsides, in urbanized areas, and in low density forests. A greenhouse study was conducted to determine efficacy of six herbicide treatments applied at reduced rates in 2005 and again in 2006 for bird vetch seedling control. Bird vetch seedlings were tolerant of reduced rates of chlorsulfuron and 2,4-DB; however, complete control was achieved with rates of clopyralid, dicamba plus diflufenzopyr, triclopyr, and 2,4-D that were a fourth to an eighth of the full registered rate. These results will be important for developing effective, low-cost methods for controlling bird vetch in Alaska, especially on the outer margins of infestations.

Herbicides were directed to either the lower 2 cm of the cotton stem or to the lower 50% of the cotton stem to determine the impact of application timing and placement on cotton response. Glyphosate + diuron resulted <= 22% injury when applied high on the stem and <= Ez 8% injury when applied low on the stem. Regardless of application placement or timing, no yield reductions were observed as a result of glyphosate + diuron application. Conversely, flumioxazin + MSMA applications resulted in 93 and 64% injury when applied high POST-directed (HPD) to 20- and 30-cm cotton, respectively. Low POST-directed (LPD) applications caused 33 and 23% injury to 20- and 30-cm cotton, respectively. In both years, HPD applications of flumioxazin + MSMA on 20-cm cotton resulted in excessive yield loss (94 to 87%), whereas yield loss was only noted in 30-cm cotton in 2004.

Additionally, LPD applications of flumioxazin + MSMA, though causing significant visual injury, did not result in a yield reduction at any application timing. Although cotton became more tolerant to flumioxazin + MSMA as the season progressed, the research suggests that applications of flumioxazin should be made with precision or delayed until cotton reaches 40 cm in height.

Seedling emergence was >= 50% from tropical soda apple fruit > 1.8 cm in diameter. Tropical soda apple overwintering emergence was 14, 10, 48, 42, and 13% from seed alone and 86, 83, 48, 41, and 18% for seeds in tropical soda apple fruit over-wintering at 100, 0, - 5, - 10, and - 15 cm from the soil surface, respectively. Before frost (early November), average tropical soda apple plant heights were 0.8, 0.6, and 0.7 m; plant diameters were 2.6, 1.7, and 2 m; fruit produced per tropical soda apple plant were 415, 342, 128; and plant weights were 9.9, 9.5, and 4.9 kg at 27 wk after transplanting (WATP) for 1996, 1997, and 1998, respectively. Regeneration from overwintering tropical soda apple roots varied depending on the winter conditions. These results suggest that tropical soda apple plants can survive mild winters.

McCain, Cindy TI In situ gene conservation of six conifers in western Washington and Oregon SO WESTERN JOURNAL OF APPLIED FORESTRY LA English DT Article DE gap analysis; biodiversity; genetic resources; conservation planning; GIS ID BRITISH-COLUMBIA; ISOZYME VARIATION; RESOURCES AB A gap analysis was conducted to evaluate the extent to which genetic resources are conserved in situ in protected areas for six conifer species in the Pacific Northwest (Sitka spruce, sugar pine, western white pine, ponderosa pine, western redcedar, and western hemlock). The gap analysis involved producing a GIS database detailing the location of protected areas and the distribution and abundance of tree species as inferred from data on potential plant association groups, actual plant associations, and actual land cover type. We used two schemes for stratifying the distribution of each species into genetic populations for gap analysis: seed zones and ecoregions. The results show that most seed zones and ecoregions contain at least 5,000 mature individuals in protected areas, indicating strong in situ gene conservation. Protection is less complete, however, for western white pine in the Puget lowlands, where urbanization and disease have reduced populations below safe levels. These populations represent the highest priority for additional gene conservation. Other species and areas warranting further evaluation include Sitka spruce in some parts of the Puget lowlands, remnant western white pine stands in the Oregon Coast Range, and sugar pine within the white pine blister rust zone.

Yoder, Jonathan TI Estimating suppression expenditures for individual large wildland fires SO WESTERN JOURNAL OF APPLIED FORESTRY LA English DT Article DE regression analysis; cost; fire characteristics AB The extreme cost of fighting wildland fires has brought fire suppression expenditures to the forefront of budgetary and policy debate in the United States. inasmuch as large fires are responsible for the bulk of fire suppression expenditures, understanding fire characteristics that influence expenditures is important for both strategic fire planning and onsite fire management decisions. These characteristics then can be used to produce estimates of suppression expenditures for large wildland fires for use in wildland fire decision support or after-fire reviews. The primary objective of this research was to develop regression models that could be used to estimate expenditures on large wildland fires based on area burned, variables representing the fire environment, values at risk, resource availability, detection time, and National Forest System region. Variables having the largest influence on cost included fire intensity level, area burned, and total housing value within 20 mi of ignition. These equations were then used to predict suppression expenditures on a set of fiscal year 2005 Forest Service fires for the purpose of detecting "extreme" cost fires-those fires falling more than 1 or 2 SDs above or below their expected value.

This study was conducted in a 47-year-old Douglas-fir (Pseudotsuga menziesii stand in northwest Oregon. First, we evaluated the effects of root system infection on diameter and height growth. Growth rates were lowest in trees with high infection levels; root infection level affected diameter growth more than height growth. Second, we evaluated the effects of fumigation treatments on tree growth. The nine treatments were as follows: three dosages of methylisothiocyanate (MITO, four dosages of chloropicrin (trichloronitromethane), one dosage of Vorlex [20% MIN, 80% chlorinated C-3 hydrocarbons (v/v)], and a control. The fumigants were applied by inserting them into holes drilled into the base of live trees. After nine growing seasons, all three of the treatments applying different dosages of MITC and the treatment applying the lowest dosage of chloropicrin had higher tree survival rates than the untreated control, and the growth rates in those four fumigation treatments were not significantly different from growth in the surviving control trees.

TI Polymorphic Indian ricegrass populations result from overlapping waves of migration SO WESTERN NORTH AMERICAN NATURALIST LA English DT Article DE seed polymorphism; migration; seed dormancy ID NATURAL HYBRIDS; REPRODUCTION; ORYZOPSIS; DORMANCY; PALOMA; STIPA; MODE AB Indian ricegrass (Achnatherum hymenoides [Roem. & Schult.] Barkworth) is a rangeland species native to western North America with populations that may exhibit distinct seed-size morphs borne on separate plants. These morphs are often associated with very different levels of seed dormancy. We compared RAN) profiles of the relatively infrequent and highly dormant jumbo seed morph to its more germinable small or large (non-jumbo) companion seed morphs collected front 9 sites where they were sympatric. Jumbo seed accessions from 9 additional sites that did not exhibit seed polymorphism were included to better sample this seed morph across the species range. Sympatric seed morphs were consistently distinguishable by their RAPD profiles, and sympatric seed morphs were no more likely to cluster together than nonsympatric seed morphs. The ability of sympatric seed morplis to maintain their genetic identity is compatible with the hypothesis of a predominately autogamous breeding system. Furthermore, these; data support the hypothesis that local polymorphic populations result from overlapping waves of migration with distinct geographical origins. The jumbo seed morphs exhibited moderate correlation between genetic distance and geographic distance, but the non-jumbo seed morplis exhibited no such correlation. Jumbo seed morphs that were collected at or cast of the Continental Divide in New Mexico and Colorado are more genetically homogeneous than those west of the Continental Divide, and non-jumbo seed morphs from the east are more genetically variable than jumbo seed morphs from the same location,. This suggests that gene flow eastward across the Rocky Mountains has been more. frequent for the noel-jumbo seed morphs than for the jumbo seed morphs.

We compared effects between 1995 and 2003 of time-controlled, short-duration rotational grazing against season-long continuous grazing, at a moderate stocking rate (1.9.5 ha - animal unit month(-1)), oil livestock gains and on foliar and basal cover in short-grass steppe. Livestock average daily gains, grazing-season gains, and beef production did not differ between grazing systems. We observed]to relationship between precipitation (annual or growing-season) and average daily gain. In contrast, both grazing-season gains and beef production exhibited a significant curvilillear response to both growing-season and annual precipitation. Basal and foliar cover of all plant functional groups (C-3 annual grasses, C-3 pereunnial grasses and grass-likes, C-4 perennial grasses, cactus, annual forbs, porennial forbs, and shrubs/subshrubs) did not differ between grazing systems. Litter and flare ground were also unaffected by grazing system, with litter increasing and bare ground decreasing over the duration of this experiment. Land managers in shortgrass steppe who are; implementing rotational grazing at moderate stocking rates should not expect increased livestock gains or changes in basal and foliar cover of the plant community Rotational grazing may be a useful management tool for achieving conservation goals through modifications of seasonality and intensity of use in paddocks within larger management emits to accommodate spatial variability in vegetation and temporal variation in precipitation.

Dramatic changes to Great- Basin Desert habitats, which can potentially impact mammalian species, have occurred in some areas in Utah. We examined kit fox demo-graphics and prey populations from 1999 to 2001 on Dugway Proving Ground (DPG), a U.S. Army facility in Utah, and compared some parameters to historical levels (1976-1958, 1.966-1969). Adult survival rates were fairly consistent between 1999 and 2000 and between 1999 and 2001; however, survival was greater in 2001 than in 2000. Reproductive rates ranged from 1.0 to 3.8 pups per female in 1999-2000 and Here similar to historical numbers (1.0-4.2 pups per female). We found a decrease in pre-whelping kit fox density from the 1960s (0.12 foxes center dot km(-2)) to 1999-2001 (0.04 foxes. km(-2)); however; densities were similar between the current study and the 1950s (0.08 foxes center dot kin-2). Using 9 years of data, we found density dependence between reproductive rates of the current year and annual fox density from the previous year. Using 7 years of data, we found a slight correlation between kit fox annual density and a 1-year lag in leporid abundance, even though leporid abundance was lower during the present study than it was historically. Compared to historical levels, current small mammal abundance and species composition has changed in several habitats. Kit fox breeding density and annual density were inversely correlated with coyote (Canis latrans) density c Changes to the landscape at DPG, especially due to invasion of cheatgrass (Bromus, tectorum) and addition of artificial water sources, have caused :a change in available kit fox habitat and prey species, and have increased the abundance of coyotes, the kit fox's major competitor.

Scolytinae]) in downed host material felled during summer and spring seasons on the Wasatch Plateau in south central Utah. Thirty-three matched pairs of Engelmann spruce (Picea engelmannii Parry ex Engelm.) trees were selected for study in spring 1996. One tree of each pair was cut during August 1996 (summer-felled) and the other tree was cut in early April 1997 (spring-felled), so that trees would be colonized by spruce beetles of the same flight period. Brood adults were collected and counted from bark samples, which were removed from the top, bottom. and sides of all sample trees in October 1998. The number of emergent adults produced in June 1999 was determined from exit holes counted in bark samples removed form these same locations. Mixed-model procedures were used to compare differences in the mean number of adults produced in summer-felled verus spring-felled trees in each year. The results indicated that significantly fewer spruce beetles were produced in summer-felled trees than in spring-felled trees. More brood adults were also present in, or emerged form, unexposed hole aspects (bottom, north, and east) of sample trees than exposed aspects (top, south and west). These finding suggest that disturbances providing spruce beetles with an abundance of fresh host material in the spring result in the greatest potential for spruce beetle production, particularly beneath unexposed bark aspects. Examples of such disturbances include snow avalanches, blowdown, and snow and ice damage. C1 USDA, Forest Serv, Forest Hlth Protect Ogden Field Off, Ogden, UT 84403 USA.

TI Examination of lumber price trends for major hardwood species SO WOOD AND FIBER SCIENCE LA English DT Article DE price variability; hardwood lumber; fashion trends AB Over the last 40 years, trends in interspecies and intergrade hardwood lumber prices have been erratic. In the early 1960s, high- and midgrade hard maple commanded high prices while red oak was the least valuable lumber regardless of grade. In the 1980s, high- and midgrade oak prices surged, but prices of all grades of maple and yellow-poplar declined. During the 1990s, maple prices increased in all grades while the price of oak increased only in the lower grades. It is important to understand changes in interspecies and intergrade pricing as well as the market forces causing these changes because lumber price reflects the use of these products relative to availability. In turn, relative utilization is used to evaluate and justify the relevance of emerging, research problem areas. This paper examines changes in the interspecies prices for the major grades of hardwood lumber and relates these changes to species preferences, end markets, manufacturing processes, and sawtimber supply.

For the maleic anhydride (MA) with benzoyl peroxide (BPO) as an initiator, tensile strength increased 52% with the TMP fiber treatment over untreated laminates. The optimum strength properties were obtained with an MA and BPO ratio of 2:1. Scanning electron microscopy (SEM) images also showed the effectiveness of MA loading on the surface of TMP fibers due to increased fiber failure without fiber pullout from the polypropylene matrixes. Crystallinity and heat flow from DSC, as expected, decreased with the addition of MA on the TMP fiber surface. These results were also in accordance with the morphological observations at the fracture surface, Fourier-transform infrared spectroscopy (FTIR) spectra, and thermal analysis. Based on the high correlation between tensile strength and the number of fibers counted at the point of failures, the number of fibers proved to be a sensitive measure of the effectiveness of surface treatment.

Relative effects and benefits of thermal exposure SO WOOD AND FIBER SCIENCE LA English DT Article DE medium density fiberboards; thermal degradation; process conditions; compositional changes; carbohydrate structure; physical and mechanical properties; profile density ID MEDIUM DENSITY FIBERBOARD; PHYSICAL-PROPERTIES; RESIDUAL-STRESSES; CHEMICAL-CHANGES; POST-TREATMENT; REDUCTION; PARTICLES; STRENGTH; PANELS; MODEL AB This research evaluated the potential of wood fiber to chemically decompose during hot-pressing. We evaluated changes in carbohydrate composition and structure as a function of multiple press temperatures (180 degrees, 200 degrees, and 220 degrees C) and an array of hot-pressing durations from 180 to 2500 s. Results show how this thermal degradation in chemical composition directly results in changes in moisture sorption characteristics, physical and mechanical properties, and aboveground durability. For most mechanical properties, it appears that very little degrade occurs until mat temperatures exceed 150 degrees C. Changes in the chemistry of medium density fiberboard seem to result in measurable changes in hygroscopicity, decay, strength, and stiffness. Control of hot-press temperature and duration appears a potential method to heat-treat medium density fiberboard and enhance its serviceability. This heat-treatment effect appears to be related to cumulative thermal load/exposure; subsequent analysis and computational modeling is currently underway.

Data showed that latewood density and tracheid diameter in suppressed-growth material can vary spatially on a scale comparable to the 50-mu m resolution of the instrument used in our testing. An optical imaging method called Ring Profiler was developed to determine what effect SilviScan's resolution had on the measurements. A single suppressed-growth specimen of Douglas-fir was used to develop the method. Ring Profiler measurements of the specimen showed that SilviScan overestimated latewood tracheid radial diameters by 59% in growth rings averaging 200-mu m width. In those same growth rings, SilviScan latewood density was found to be 19% too low. In all growth rings measured by Ring Profiler, latewood wall thicknesses were anisotropic. Radial and tangential values averaged 13% less than the isotropic wall thickness calculated from SilviScan data. Ring Profiler density measurement from binarized images of wood cross-sections was found to correlate well with SilviScan X-ray density (r-squared = 0.907); however, better images and an objective method for thresholding are needed for accuracy over a large sample space. With these improvements and automated scanning of samples, Ring Profiler could be an attractive, inexpensive complement to SilviScan. C1 USDA, Forest Prod Lab, Madison, WI 53705 USA.

The average ring width successfully correlated wood density and tracheid anatomical properties of red pines (Pinus resinosa Ait.) from a never-thinned experimental plantation forest with five different initial plantation densities. The results indicate that plantation density has a pronounced effect on earlywood growth, which resulted in increased latewood volumetric fraction and uniform tracheid radial and wall thickness distribution. A similar approach of average ring width correlations may be applied to study wood and tracheid properties of trees growing in the densely populated natural forests.

This can be partially attributed to lack of a unified study on crown response to intensive management or stand health. In this analysis of several coastal Douglas-fir (Pseudotsuga menziesii var. menziesii [Mirb.] Franco) branch datasets, a significant treatment effect of fertilization, thinning, pre-commercial thinning, varying levels of vegetation control, and intensity of a foliar disease (Swiss needle cast, caused by Phaeocryptopus gaeumannii (T Rohde) Petr.) were all found to influence several key crown structural attributes. Maximum branch size and total and non-foliated crown radii were found to be the most dynamic and sensitive crown variables to the various stand factors as no treatment effects were found for the number of branches within an annual segment or branch angle. When the data sets were combined and used to develop a single predictive equation, treatment effects were largely accounted for by changes in bole and crown size as mean bias was relatively low despite the large range in tree ages examined (4-450 years at breast height). While crown structure is highly variable and sensitive to a variety of stand factors, general empirical equations perform quite well and should be better integrated into models of forest growth and yield.

A major difference between the two models is whether the soil and vegetation components of the scene are treated separately (Two-Source Energy Balance; TSEB approach) or as a lumped composite (one-source approach; Surface Energy Balance Algorithm for Land; SEBAL) in the parameterization of radiative and turbulent exchanges with the overlying air. Comparisons are performed using data from two largescale field experiments covering sub-humid grassland (Southern Great Plains '97) and semi-arid rangeland (Monsoon '90) having very different landscape properties. In general, there was reasonable agreement between flux output from both models versus a handful of flux tower observations. However, spatial intercomparisons of model output over the full modeling domains yielded relatively large discrepancies (on the order of 100 W m(-2)) in sensible heat flux (H) that are related to land cover. In particular, bare soil and sparsely vegetated areas yielded the largest discrepancies, with TSEB fluxes being in better agreement with tower observations. Modifications to SEBAL inputs that reduced discrepancies with TSEB and observations for bare soil and shrub classes tended to increase differences for other land cover classes. In particular, improvements to SEBAL inputs of surface roughness for momentum tended to exacerbate errors with respect to observed fluxes. These results suggest that some of the simplifying assumptions in SEBAL may not be strictly applicable over the wide range in conditions present within these landscapes. An analysis of TSEB and SEBAL sensitivity to uncertainties in primary inputs indicated that errors in surface temperature or surface-air temperature differences had the greatest impact on H estimates. Inputs of secondary importance were fractional vegetation cover for TSEB, while for SEBAL, the selection of pixels representing wet and dry moisture end-member conditions significantly influenced flux predictions. The models were also run using input fields derived from both local and remote data sources, to test performance under conditions of varying ancillary data availability. In this case, both models performed similarly under both constraints. (c) 2007 Elsevier Inc. All rights reserved. C1 Int Inst Geoinformat Sci & Earth Observ, NL-7500 AA Enschede, Netherlands.

Remotely sensed hyperspectral imagery has the potential to provide important information about fine-scale ground cover components that are indicative of burn severity after large wildland fires. Airborne hyperspectral imagery and ground data were collected after the 2002 Hayman Fire in Colorado to assess the application of high resolution imagery for burn severity mapping and to compare it to standard burn severity mapping methods. Mixture Tuned Matched Filtering (MTMF), a partial spectral unmixing algorithm, was used to identify the spectral abundance of ash, soil, and scorched and green vegetation in the burned area. The overall performance of the MTMF for predicting the ground cover components was satisfactory (r(2) = 0.21 to 0.48) based on a comparison to fractional ash, soil, and vegetation cover measured on ground validation plots. The relationship between Landsat-derived differenced Normalized Burn Ratio (dNBR) values and the ground data was also evaluated (r(2) -0.20 to 0.58) and found to be comparable to the MTMF. However, the quantitative information provided by the fine-scale hyperspectral imagery makes it possible to more accurately assess the effects of the fire on the soil surface by identifying discrete ground cover characteristics. These surface effects, especially soil and ash cover and the lack of any remaining vegetative cover, directly relate to potential postfire watershed response processes. (c) 2006 Elsevier Inc.

Peanut (Arachis sp.), squash (Cucurbita moschata), and cotton (Gossypium barbadense) macrofossils were excavated from archaeological sites on the western slopes of the northern Peruvian Andes. Direct radiocarbon dating indicated that these plants grew between 9240 and 5500 C-14 years before the present. These and other plants were recovered from multiple locations in a tropical dry forest valley, including household clusters, permanent architectural structures, garden plots, irrigation canals, hoes, and storage structures. These data provide evidence for early use of peanut and squash in the human diet and of cotton for industrial purposes and indicate that horticultural economies in parts of the Andes took root by about 10,000 years ago.

Sediment concentrations and total event sediment yields were related to storm-runoff characteristics, and statistical relationships were developed to estimate sediment yields for events with missing data. Precipitation ranged from 263 to 298 mm yr(-1), runoff ranged from 8.2 to 26.4 mm yr(-1), and sediment yields ranged from 0.07 to 5.7 t ha(-1) yr(-1), with an areal average of 2.2 t ha(-1) yr(-1). For six of the seven watersheds, between 6 and 10 events produced 50% of the total sediment yields over the 11-year period. On the seventh watershed, two storms produced 66% of the sediment because of differences in the geomorphology and vegetation characteristics of that area. Differences between sediment yields from all watersheds were attributable to instrumentation, watershed morphology, degree of channel incision, and vegetation.

TI Quantitative analysis of cotton (Gossypium hirsutum) lint trash by fluorescence spectroscopy SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article DE cotton (Gossypium hirsutum); trash; chemometrics; fluorescence AB The presence of cotton plant botanical components, or trash, embedded in lint subsequent to harvesting and ginning is an important criterion in the classification of baled cotton by the U.S. Department of Agriculture Agricultural Marketing Service. The trash particles may be reduced in size to the point that specific trash types are not identifiable by image or gravimetric analysis, and it is desirable to quantify different trash types so that processing lines may be optimized for removal of the most problematic trash to enhance processing performance and cotton lint quality. Currently, there are no methods available to adequately quantify cotton lint trash based on botanical origin. The present work attempts to address this issue through the analysis by fluorescence spectroscopy of dimethyl sulfoxide extracts of mixtures of six botanical trash types. The fluorescence data are subsequently subjected to chemometric analysis. The resulting 6 partial least-squares calibration models obtained from 128 mixtures are demonstrated in the case of leaf and hull to be capable of predicting individual trash component concentrations with a high degree of confidence.

The method consists of extraction followed by colorimetric quantification. The colorimetric quantification was based on the formation of red to orange colored derivatives resulting from the treatment of limonin, limonin glucoside, or a fruit extract with 4-(dimethylamino)benzaldehyde (DMAB) in the presence of perchloric and acetic acids. Absorbance maxima for the limonin and limonin glucoside derivatives were found to be 470 and 503 nm, respectively. The influence of DMAB concentration, reaction time, and solvent composition on color development and sensitivity were investigated and optimal assay conditions established. With a microplate format under these conditions, the limits of detection and quantification were determined to be 0.25 and 0.50 mu g/mL for limonin and 0.50 and 1.0 mu g/mL for limonin glucoside.

The addition of 2% hydroxypropyl methylcellulose improved bread based on 105% water, 70% sorghum flour, and 30% potato starch. Nevertheless, a flat top and tendency toward a hole in the crumb remained. Sourdough fermentation of the total sorghum flour eliminated these problems. Size-exclusion high-performance liquid chromatography demonstrated that during sourdough fermentation, proteins from the dough liquid were degraded to peptides smaller than kafirin monomers (< 19 kDa). Laser scanning confocal microscopy showed aggregated protein in bread crumb without sourdough fermentation, whereas with sourdough fermentation, only small isolated patches of protein bodies embedded in matrix protein remained. In oscillatory temperature sweeps, sourdough fermentation caused a significantly higher resistance to deformation (vertical bar G*vertical bar) after gelatinization of the above batter relative to batters without sourdough.

TI Ethylene and alpha-farnesene metabolism in green and red skin of three apple cultivars in response to 1-methylcyclopropene (1-MCP) treatment SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article DE Apple; Malus domestica; ethylene; alpha-farnesene synthesis; conjugated trienes; gene expression; superficial scald; physiological disorder ID SUPERFICIAL SCALD DEVELOPMENT; GRANNY-SMITH APPLES; CONJUGATED TRIENOL CONCENTRATIONS; LONG-TERM STORAGE; STORED APPLES; FUNCTIONAL DISORDER; OXIDATION-PRODUCTS; PEEL TISSUE; FRUIT; EXPRESSION AB Relationships among alpha-farnesene synthesis and oxidation, ethylene production and perception, antioxidative enzyme activities, and superficial scald development in fruit of three commercial apple cultivars were investigated at the biochemical and gene transcriptional levels. Scald-susceptible Cortland and Law Rome and scald-resistant Idared apples were untreated or treated with the ethylene action inhibitor 1-methylcyclopropene (1-MCP) and stored for up to 25 weeks at 0.5 degrees C. Separate blushed (red) and unblushed (green) peel tissue samples were taken at harvest and after 2, 4, 6, 10, 15, 20, and 25 weeks of storage. Large increases in peel tissue concentrations of alpha-farnesene and its conjugated trienol (CTol) oxidation products occurred in untreated Cortland and Law Rome and were about 4-9-fold greater than those in Idared. In both Cortland and Law Rome, accumulation of CTols in green peel was nearly twice that in red peel. 1-MCP treatment delayed and attenuated alpha-farnesene and CTol accumulation in each cultivar. Activities of peroxidase (POX) and catalase (CAT) were lower in red peel than in green peel, with the exception of CAT in Law Rome, whereas no effects of 1-MCP on enzyme activities were detected except for Cortland. In control fruit, internal ethylene concentrations (IECs) increased during the first 4-6 weeks to reach highest levels in Cortland, intermediate levels in Law Rome, and low levels in Idared. In 1-MCP-treated fruit, IECs increased gradually to modest levels by 25 weeks in Cortland and Law Rome but were almost nil in Idared. Expression patterns of the alpha-farnesene synthase gene MdAFS1, the ethylene receptor gene MdERS1, and the ethylene biosynthetic genes MdACS1 and MdACO1 were generally in accord with the patterns of alpha-farnesene and ethylene production. In particular, MdAFS1 and MdACS1 showed similar patterns of expression in each cultivar. Among the controls, transcript levels increased more rapidly in Cortland and Law Rome than in Idared during the first few weeks of storage. In 1-MCP-treated fruit, transcript abundance in Cortland and Law Rome rose to untreated control levels after 10-15 weeks but remained low in Idared. Scald symptoms were restricted to unblushed skin, and the incidence in controls after 25 weeks was nearly 100% in Cortland and Law Rome compared with 1% in Idared. 1-MCP treatment reduced scald incidence to 14, 3, and 0% in Cortland, Law Rome, and Idared, respectively. Overall, the results support the proposed role of CTols in scald induction and indicate that alpha-farnesene synthesis is tightly regulated by ethylene. However, gene transcription alone does not account for the big differences in ethylene and alpha-farnesene production in Cortland, Law Rome, and Idared apples.

TI Sorghum bran in the diet dose dependently increased the excretion of catechins and microbial-derived phenolic acids in female rats SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article DE sorghum; procyanidins; catechin; epicatechin; phenolic acids ID MASS-SPECTROMETRY; CONDENSED TANNINS; COCOA PROCYANIDINS; URINARY-EXCRETION; BLACK TEA; PROANTHOCYANIDINS; (-)-EPICATECHIN; HUMANS; (+)-CATECHIN; POLYPHENOLS AB Sorghum bran is concentrated with procyanidins (predominately polymers), which may be beneficial for health in humans; however, the bioavailability of procyanidins is not well-understood. Female Sprague-Dawley rats were fed an AIN93G diet containing 0, 5, 10, 20, or 40% Hi-tannin sorghum bran (n = 5-7 for each group) for 50 days. Sorghum bran contained 23.3 mg/g of procyanidins. The urinary excretions of catechin, epicatechin, methylated catechins, and phenolic acids were analyzed using liquid chromatography-tandem mass spectrometry. Sorghum bran dose dependently increased the urinary excretion of catechin (0-2.2 nmol/day) and 3'-O-methylcatechin (0-9.5 nmol/day). Their serum concentrations also increased with dose (range of 0-14 nM for 3'-O-methylcatechin). Among the 14 phenolic acids analyzed, 3,4-dihydroxybenzoic acid, 3-methoxy-4-hydroxybenzoic acid, and 4-hydroxyphenylacetic acid dominated in the serum (1.8-8 mu mol/L). In the urine, 3-methoxy-4-hydroxyphenylacetic acid, 3-hydroxyphenylacetic acid, and 3-hydroxyphenylpropionic acid dominated and their excretion increased significantly with the level of sorghum bran in the diet. The summed phenolic acid excretion was 0.8 mu mol/day in the control group and increased to 23 mu mol/day for 40% sorghum bran group. The hippuric acid excretion ranged from 2.2 to 16.2 mu mol/day and peaked in the 10% sorghum bran group. On the basis of chromic oxide, a nonabsorbable marker, total procyanidins and polymers disappeared progressively, and significant degradation occurred in the cecum and colon. Catechins and procyanidins in sorghum were bioavailable; however, bacteria-derived phenolic acids were the predominant metabolites of procyanidins. Procyanidins degraded in the gastrointestinal tract. Depolymerization was not observed. C1 USDA, Arkansas Childrens Nutr Ctr, Agr Res Serv, Little Rock, AR 72202 USA.

TI Effect of dose size on bioavailability of acylated and nonacylated anthocyanins from red cabbage (Brassica oleracea L. var. capitata) SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article DE anthocyanin; cyanidin; acylated; bioavailability; cabbage (Brassica oleracea L. var. capitata) ID PERFORMANCE LIQUID-CHROMATOGRAPHY; TANDEM-MASS-SPECTROMETRY; SWEET-POTATO; CELL-PROLIFERATION; UNITED-STATES; RICH EXTRACTS; ELDERLY WOMEN; COMMON FOODS; COLON-CANCER; ABSORPTION AB Recent studies indicate that anthocyanin intake conveys a variety of health benefits, which depend on absorption and metabolic mechanisms that deliver anthocyanins and their bioactive metabolites to responsive tissues. The anthocyanin bioavailability of red cabbage (Brassica oleracea L. var. capitata) was evaluated as reflected by urinary excretion of anthocyanins and anthocyanin metabolites. Twelve volunteers consumed 100, 200, and 300 g of steamed red cabbage (containing 1.38 mu mol of anthocyanins/g of cabbage) in a crossover design. Anthocyanin concentration in cabbage extract and urine was measured by HPLC-MS/MS. Six nonacylated and 30 acylated anthocyanins were detected in red cabbage, and 3 nonacylated anthocyanins, 8 acylated anthocyanins, and 4 metabolites were present in urine. Mean 24 h excretion of intact anthocyanins increased linearly from 45 (100 g dose) to 65 nmol (300 g dose) for acylated anthocyanins and from 52 (100 g dose) to 79 nmol (300 g dose) for nonacylated anthocyanins. Urinary recovery of intact anthocyanins (percent of anthocyanin intake) decreased linearly from 0.041% (100 g dose) to 0.020% (300 g dose) for acylated anthocyanins and from 0.18% (100 g dose) to 0.09% (300 g dose) for nonacylated anthocyanins. Anthocyanin metabolites consisted of glucuronidated and methylated anthocyanins. The results show that red cabbage anthocyanins were excreted in both intact and metabolized forms and that recovery of nonacylated anthocyanins in urine was > 4-fold that of acylated anthocyanins.

Chen, Dan Nene, Vishvanath TI Structure and evolution of a proviral locus of Glyptapanteles indiensis bracovirus SO BMC MICROBIOLOGY LA English DT Article ID GENOME SEQUENCE; SYMBIONT; FAMILIES AB Background: Bracoviruses (BVs), a group of double-stranded DNA viruses with segmented genomes, are mutualistic endosymbionts of parasitoid wasps. Virus particles are replication deficient and are produced only by female wasps from proviral sequences integrated into the wasp genome. Virus particles are injected along with eggs into caterpillar hosts, where viral gene expression facilitates parasitoid survival and therefore perpetuation of proviral DNA. Here we describe a 223 kbp region of Glyptapanteles indiensis genomic DNA which contains a part of the G. indiensis bracovirus (GiBV) proviral genome. Results: Eighteen of similar to 24 GiBV viral segment sequences are encoded by 7 non-overlapping sets of BAC clones, revealing that some proviral segment sequences are separated by long stretches of intervening DNA. Two overlapping BACs, which contain a locus of 8 tandemly arrayed proviral segments flanked on either side by similar to 35 kbp of non-packaged DNA, were sequenced and annotated. Structural and compositional analyses of this cluster revealed it exhibits a G+C and nucleotide composition distinct from the flanking DNA. By analyzing sequence polymorphisms in the 8 GiBV viral segment sequences, we found evidence for widespread selection acting on both protein-coding and non-coding DNA. Comparative analysis of viral and proviral segment sequences revealed a sequence motif involved in the excision of proviral genome segments which is highly conserved in two other bracoviruses. Conclusion: Contrary to current concepts of bracovirus proviral genome organization our results demonstrate that some but not all GiBV proviral segment sequences exist in a tandem array. Unexpectedly, non-coding DNA in the 8 proviral genome segments which typically occupies similar to 70% of BV viral genomes is under selection pressure suggesting it serves some function(s). We hypothesize that selection acting on GiBV proviral sequences maintains the genetic islandlike nature of the cluster of proviral genome segments described herein. In contrast to large differences in the predicted gene composition of BV genomes, sequences that appear to mediate processes of viral segment formation, such as proviral segment excision and circularization, appear to be highly conserved, supporting the hypothesis of a single origin for BVs.

TI Comparison of two different physical activity monitors SO BMC MEDICAL RESEARCH METHODOLOGY LA English DT Article ID DOUBLY LABELED WATER; ACCELEROMETRY; RELIABILITY; VALIDATION AB Background: Understanding the relationships between physical activity (PA) and disease has become a major area of research interest. Activity monitors, devices that quantify free-living PA for prolonged periods of time (days or weeks), are increasingly being used to estimate PA. A range of different activity monitors brands are available for investigators to use, but little is known about how they respond to different levels of PA in the field, nor if data conversion between brands is possible. Methods: 56 women and men were fitted with two different activity monitors, the Actigraph((TM)) (Actigraph LLC; AGR) and the Actical((TM)) (Mini-Mitter Co.; MM) for 15 days. Both activity monitors were fixed to an elasticized belt worn over the hip, with the anterior and posterior position of the activity monitors randomized. Differences between activity monitors and the validity of brand inter-conversion were measured by t-tests, Pearson correlations, Bland-Altman plots, and coefficients of variation (CV). Results: The AGR detected a significantly greater amount of daily PA (216.2 +/- 106.2 vs. 188.0 +/- 101.1 counts/ min, P < 0.0001). The average difference between activity monitors expressed as a CV were 3.1 and 15.5% for log- transformed and raw data, respectively. When a conversion equation was applied to convert datasets from one brand to another, the differences were no longer significant, with CV's of 2.2 and 11.7%, log- transformed and raw data, respectively. Conclusion: Although activity monitors predict PA on the same scale (counts/ min), the results between these two brands are not directly comparable. However, the data are comparable if a conversion equation is applied, with better results for log- transformed data.

Levan was first blended with glycerol and a concurrent change in glass transition temperature (Tg) using differential scanning calorimetry (DSC) was observed. Levan was made into films by pressing the levan/glycerol blends on a heated compression molder. It was found that films with 20-30 weight percent (wt%) glycerol made cohesive, pliable films. However, films with less than 10 wt% glycerol were too brittle to handle and test. Films with greater than 30 wt% glycerol were not cohesive and were more "liquid"-like than "solid"-like. It was found that 20 wt% glycerol was a critical point for effective levan plasticization. Based on the compression-molding data, levan was extruded using optimal glycerol contents and heating regimes. Efficient extrusion of levan/glycerol blends required at least 35% glycerol, indicating extrusion may better incorporate glycerol into the levan structure over room temperature mixing and heated compression-molding. Adding water to the blend, either by replacing glycerol or levan, greatly reduced extrusion viscosity. Published by Elsevier Ltd.

A method is described that uses high performance size exclusion chromatography coupled with multiangle laser light scattering and refractive index detectors to determine amylose content, molecular mass of amylose and the weight- and molar-based distributions of degree of polymerization (DP) of amylose and the fine structure of amylopectin. The method is relatively rapid with the coefficient of variation less than 5% for most aspects of the molecular characterization. It should find utility in research programs studying the association between starch molecular characteristics and functionality, and in starch-related genetics studies of diverse botanical sources.

TI A photoactive isoprenoid diphosphate analogue containing a stable phosphonate linkage: Synthesis and biochemical studies with prenyltransferases SO JOURNAL OF ORGANIC CHEMISTRY LA English DT Article ID RUBBER ELONGATION-FACTOR; FARNESYL-PROTEIN TRANSFERASE; GERANYLGERANYLTRANSFERASE TYPE-I; HEVEA-BRASILIENSIS; MASS-SPECTROMETRY; BIOSYNTHESIS; PURIFICATION; FARNESYLTRANSFERASE; INHIBITORS; PYROPHOSPHATE AB A number of biochemical processes rely on isoprenoids, including the post-translational modification of signaling proteins and the biosynthesis of a wide array of compounds. Photoactivatable analogues have been developed to study isoprenoid utilizing enzymes such as the isoprenoid synthases and prenyltransferases. While these initial analogues proved to be excellent structural analogues with good cross-linking capability, they lack the stability needed when the goals include isolation of cross-linked species, tryptic digestion, and subsequent peptide sequencing. Here, the synthesis of a benzophenone-based farnesyl diphosphate analogue containing a stable phosphonophosphate group is described. Inhibition kinetics, photolabeling experiments, as well as X-ray crystallographic analysis with a protein prenyltransferase are described, verifying this compound as a good isoprenoid mimetic. In addition, the utility of this new analogue was explored by using it to photoaffinity label crude protein extracts obtained from Hevea brasiliensis latex. Those experiments suggest that a small protein, rubber elongation factor, interacts directly with farnesyl diphosphate during rubber biosynthesis. These results indicate that this benzophenone-based isoprenoid analogue will be useful for identifying enzymes that utilize farnesyl diphosphate as a substrate.

The intent was to develop and propose international standard guidelines for models based on animal species that would gain acceptance worldwide. Parameters essential for the development of long-term and short-term infection models were outlined and harmonized to provide a "best.fit" JD challenge model for cattle, goats, sheep, cervids, and mice. These models will be useful to study host-pathogen interactions, host immunity at the local and systemic level, and for evaluating vaccine candidates and therapeutics. The consensus guidelines herein list by animal species strains of Mycobacterium avium subsp. paratuberculosis used, challenge dose, dose frequency, age of challenge, route of challenge, preparation of inoculum, experimental animal selection, quality control, minimal experimental endpoints and other parameters.

TI Evidence of varietal adaptation to organic farming systems SO FIELD CROPS RESEARCH LA English DT Article DE plant breeding; genotype x system interaction; organic agriculture; wheat; indirect selection ID WHEAT CULTIVARS; WINTER-WHEAT; LOW-INPUT; NITROGEN; ENVIRONMENTS; SELECTION; YIELD; LINES; SUSTAINABILITY; PRODUCTIVITY AB Consumer demand regarding the impacts of conventional agriculture on the environment and human health have spurred the growth of organic farming systems; however, organic agriculture is often criticized as low-yielding and unable to produce enough food to supply the world's population. Using wheat as a model crop species, we show that poorly adapted cultivars are partially responsible for the lower yields often found in organic farming systems when compared with conventional farming systems. Our results demonstrate that the highest yielding soft white winter wheat genotypes in conventional systems are not the highest yielding genotypes in organic systems. An analysis of variance for yield among 35 genotypes between paired organic and conventional systems showed highly significant (P < 0.001) genotype x system interactions in four of five locations. Genotypic ranking analysis using Spearman's rank correlation coefficient (R-S) showed no correlation between genotypic rankings for yield in four of five locations; however, the ranks were correlated for test weight at all five locations. This indicates that increasing yield in organic systems through breeding will require direct selection within organic systems rather than indirect selection in conventional systems. Direct selection in organic systems produced yields 15%, 7%, 31% and 5% higher than the yields resulting from indirect selection for locations 1-4, respectively. With crop cultivars bred in and adapted to the unique conditions inherent in organic systems, organic agriculture will be better able to realize its full potential as a high-yielding alternative to conventional agriculture.

TI Accuracy of the FAMACHA system for on-farm use by sheep and goat producers in the southeastern United States SO VETERINARY PARASITOLOGY LA English DT Article DE FAMACHA; gastrointestinal nematode; goats; Haemonchus contortus; sheep ID RESOURCE-POOR CONDITIONS; EYE COLOR CHART; CLINICAL ANEMIA; HAEMONCHUS SPP.; BREEDING SHEEP; SOUTH-AFRICA; NEMATODES; RESISTANCE; COUNTS AB FAMACHA (c) is a practical on-farm system designed to provide small ruminant producers a too] for improving their management of Haemonchus contortus infections. Although this system has become very popular and widely accepted by small ruminant producers in many regions of the southern United States, there is very limited data reported on the effectiveness of the FAMACHA system when performed by farmers. The objective of this study was to evaluate the accuracy of the FAMACHA system for on-farm use by small ruminant producers during the summer season. Small ruminant producers from Georgia, Louisiana, Florida, and Puerto Rico were trained to use the FAMACHA system by veterinarians and scientists experienced with this method. FAMACHA scores were assigned at least every 2 weeks by producers to weaned and mature sheep (n = 552) and goats (n = 676) of various breeds and ages between April and September 2004. At intervals that varied among farms from 2 to 8 weeks, researchers determined body condition scores (BCS; 1 = thin and 5 = fat) and collected blood and feces from a group of animals selected randomly to determine packed cell volume (PCV) and fecal egg counts (FEC). Two separate anemia thresholds were evaluated; these were defined by either FAMACHA score (>= 3 versus >= 4) or PCV (<= 19 versus <= 15%). The correlation between FAMACHA scores and PCV or FEC was high for both sheep and goats (P < 0.001). Specificity was maximized when FAMACHA scores of 4 and 5 were considered anemic, but sensitivity was low. Sensitivity for detecting anemic animals was 50% for sheep and 89% for goats when eye score values of >= 3 were considered anemic and PCV cutoff was <= 15%. The percentage of false negatives (anemic animals not identified by FAMACHA evaluation) was less than 5% in sheep and less than I% in goats when FAMACHA scores > 3 were considered anemic and PCV cutoff was <= 15%. In both sheep and goats, predictive value of a negative was greater than 90% for all anemia and eye score categories. These data indicate that the FAMACHA method used by producers is a valuable tool for identifying anemic sheep and goats in the southern United States and Puerto Rico. Published by Elsevier B.V.

In this work, a head-to-tail tandem construct of porcine circovirus capable of generating unit-length genomic DNA in Escherichia coli was employed to examine the role of the stein-loop structure with respect to the RCR initiation and termination process. The advantage of using a head-to-tail tandem construct is that the initiation and termination sites for generation of the unit-length viral genomes are physically separated, which allows independent examination of the initiation/termination processes. Nucleotide substitution mutational analysis showed that a pair of inverted repeats capable of forming a stem-loop structure was essential for termination, but not for initiation. The results also demonstrated that it is the stem-loop configuration, not nucleotide sequence specificity, that is critical for terminating RCR DNA replication. Published by Elsevier Inc.

Little is known about the relations of natriuretic peptides and homocysteine to arterial wall stiffness in the community. Methods and Results - We assessed the relations of plasma N- terminal atrial natriuretic peptide, B- type natriuretic peptide, adrenomedullin, and homocysteine concentrations to arterial stiffness in participants in the Framingham Heart Study. Central pulse pressure, forward pressure wave, reflected pressure wave, carotid- femoral pulse wave velocity, and carotid- radial pulse wave velocity were assessed by tonometry in 1962 participants ( mean age, 61 years; 56% women) in the Framingham Heart Study. Central systolic and diastolic blood pressures were 123/75 mm Hg in men and 119/66 mm Hg in women. After adjustment for age and clinical covariates, N- terminal atrial natriuretic peptide and B- type natriuretic peptide were associated with carotid- femoral pulse wave velocity ( men: partial correlation, 0.069, P = 0.043 and r = 0.115, P = 0.001, respectively; women: r = -0.063, P = 0.037 and r = -0.062, P = 0.040), and carotid- radial pulse wave velocity ( men: r = -0.090, P = 0.009 and r = -0.083, P <= 0.015; women: r = -0.140, P <= 0.001 and r = -0.104, P = 0.001, respectively). In men, N- terminal atrial natriuretic peptide and B- type natriuretic peptide also were associated with forward and reflected wave and carotid pulse pressure. In men, adrenomedullin was associated with mean arterial pressure ( r = 0.089, P = 0.009), and homocysteine was associated with carotid- femoral pulse wave velocity ( r = 0.072, P = 0.036), forward pressure ( r = 0.079, P = 0.02), and central pulse pressure ( r = 0.072, P = 0.035). Interaction tests indicated sex differences in the relations of several biomarkers to measures of arterial stiffness. Conclusions - Plasma natriuretic peptide, adrenomedullin, and homocysteine levels are associated with alterations in conduit vessel properties that differ in men and women.

We used satellite data, government agency records, and aerial photography to examine a forest landscape in southwest Oregon that burned in 1987 and then was subject, in part, to salvage-logging and conifer planting before it reburned during the 2002 Biscuit Fire. Areas that burned severely in 1987 tended to reburn at high severity in 2002, after controlling for the influence of several topographical and biophysical covariates. Areas unaffected by the initial fire tended to burn at the lowest severities in 2002. Areas that were salvage-logged and planted after the initial fire burned more severely than comparable unmanaged areas, suggesting that fuel conditions in conifer plantations can increase fire severity despite removal of large woody fuels.

A genomic resource for large-scale studies of this parasite has been lacking. To study gene expression involved in Ich pathogenesis and virulence, our goal was to generate expressed sequence tags (ESTs) for the development of a powerful microarray platform for the analysis of global gene expression in this species. Here, we initiated a project to sequence and analyze over 10,000 ESTs. Results: We sequenced 10,368 EST clones using a normalized cDNA library made from pooled samples of the trophont, tomont, and theront life-cycle stages, and generated 9,769 sequences (94.2% success rate). Post-sequencing processing led to 8,432 high quality sequences. Clustering analysis of these ESTs allowed identification of 4,706 unique sequences containing 976 contigs and 3,730 singletons. These unique sequences represent over two million base pairs (similar to 10% of Plasmodium falciparum genome, a phylogenetically related protozoan). BLASTX searches produced 2,518 significant (E-value < 10(-5)) hits and further Gene Ontology (GO) analysis annotated 1,008 of these genes. The ESTs were analyzed comparatively against the genomes of the related protozoa Tetrahymena thermophila and P. falciparum, allowing putative identification of additional genes. All the EST sequences were deposited by dbEST in GenBank (GenBank: EG957858-EG966289). Gene discovery and annotations are presented and discussed. Conclusion: This set of ESTs represents a significant proportion of the Ich transcriptome, and provides a material basis for the development of microarrays useful for gene expression studies concerning Ich development, pathogenesis, and virulence.

Simunek, Jirka TI Leaching requirement for soil salinity control: Steady-state versus transient models SO AGRICULTURAL WATER MANAGEMENT LA English DT Article DE imperial valley; leaching fraction; irrigation; drainage ID REDUCED-RUNOFF IRRIGATION; IMPERIAL-VALLEY; WATER; CALIFORNIA; SALT; TRANSPORT AB Water scarcity and increased frequency of drought conditions, resulting from erratic weather attributable to climatic change or alterations in historical weather patterns, have caused greater scrutiny of irrigated agriculture's demand on water resources. The traditional guidelines for the calculation of the crop-specific leaching requirement (LR) of irrigated soils have fallen under the microscope of scrutiny and criticism because the commonly used traditional method is believed to erroneously estimate LR due to its assumption of steady-state flow and disregard for processes such as salt precipitation and preferential flow. An over-estimation of the LR would result in the application of excessive amounts of irrigation water and increased salt loads in drainage systems, which can detrimentally impact the environment and reduce water supplies. The objectives of this study are (i) to evaluate the appropriateness of the traditional steady-state method for estimating LR in comparison to the transient method and (ii) to discuss the implications these findings could have on irrigation guidelines and recommendations, particularly with respect to California's Imperial Valley. Steady-state models for calculating LR including the traditional model, which is an extension of the original U.S. Salinity Laboratory LR model, WATSUIT model, and water-production-function model were compared to transient models including TETrans and UNSATCHEM. The calculated LR was lower when determined using a transient approach than when using a steady-state approach. Transient conditions and the influence of preferential flow did not have as significant an effect on lowering the LR as salt precipitation for a representative study of the Imperial Valley using Colorado River water (EC = 1.23 dS/m) for irrigation. A valley-wide LR of 0.08 for a crop rotation of alfalfa/alfalfa/alfalfa/alfalfa/wheat/lettuce, as calculated by both WATSUIT and UNSATCHEM, was concluded to be the most reasonable estimate for the entire Imperial Valley as compared to a LR of 0.13 by the commonly used traditional method. The reduced LR for the Imperial Valley would result in a diminished drainage volume of approximately 1.23 X 10(8) m(3) (i.e., 100,000 ac-ft). The most significant conclusion derived from the comparison is that the use of the traditional steady-state model for estimating LR needs to be reevaluated. (c) 2007 Elsevier B.V.

The Healthy Forest Restoration Act and National Fire Plan establish a national commitment to reduce fire hazard and restore fire-adapted ecosystems across the USA. The primary index used to prioritize treatment areas across the nation is Fire Regime Condition Class (FRCC) computed as departures of current conditions from the historical fire and landscape conditions. This paper describes a process that uses an extensive set of ecological models to map FRCC from a departure statistic computed from simulated time series of historical landscape composition. This mapping process uses a data-driven, biophysical approach where georeferenced field data, biogeochemical simulation models, and spatial data libraries are integrated using spatial statistical modeling to map environmental gradients that are then used to predict vegetation and fuels characteristics over space. These characteristics are then fed into a landscape fire and succession simulation model to simulate a time series of historical landscape compositions that are then compared to the composition of current landscapes to compute departure, and the FRCC values. Intermediate products from this process are then used to create ancillary vegetation, fuels, and fire regime layers that are useful in the eventual planning and implementation of fuel and restoration treatments at local scales. The complex integration of varied ecological models at different scales is described and problems encountered during the implementation of this process in the LANDFIRE prototype project are addressed.

Four FQs, ciprofloxacin (CIP), enrofloxacin (ENR), norfloxacin (NOR), and ofloxacin (OFL), were conjugated to bovine serum albumin for immunogens and to ovalbumin for coating antigens. A Mab C4A9H1 raised against the CIP hapten exhibited high cross-reactivity (35-100%) with 12 of 14 FQs and detected these FQs in a ciELISA below their maximum residue levels (MRLs) with good sensitivity at 50% binding inhibition (IC50). The quantitative structure-activity relationship (QSAR) between Mab C4A9H1 and various FQs by comparative molecular field analysis (CoMFA) showed a high predictive ability with a cross-validation q(2) value of 0.866. Using a simple purification process and the broad-specificity ciELISA adapted for analysis of FQs in chicken muscle, chicken liver, honey, shrimp, and whole egg samples demonstrated recoveries of 60-93% for CIP, ENR, NOR, OFL, flumequine, and danofloxacin.

Non-sequential (NON-SEQ) and sequential (SEQ) fiber analysis sequences were compared for amylase neutral (aNDF) and acid (ADF) detergent fiber with and without correction for acid detergent residual ash in individually (Experiment 1) and batch-processed samples (Experiment 2). Hemicellulose concentration was calculated as the difference between aNDF and ADF. Samples included brassica forage, legumes, CT containing legumes and grasses. Fiber analysis sequence and ash correction affected ADF and hemicellulose independently, with fiber analysis sequence having the larger impact. Forage groups differed in response to treatment for most variables. Compared to NONSEQ analysis, SEQ analysis reduced ADF of brassica forages by 41 and 34 g/kg in Experiments 1 and 2, respectively, reduced ADF of legume forages by 22 and 34 g/kg in Experiments 1 and 2 and gave comparable increases in hemicellulose for both forage groups in both experiments. Estimates of ADF and hemicellulose in grasses were unaffected by analysis sequence. Under individual processing, ash correction reduced ADF only for brassicas (205 g/kg versus 191 g/kg for uncorrected and ash-free), but under batch processing, ADF of all forage groups was reduced by ash correction (mean 282 g/kg versus 274 g/kg for uncorrected and ash-free, respectively). The difference between NONSEQ and SEQ ADF increased with pectin concentration (r(2) = 0.30, P < 0.001). Sequential fiber analysis with correction for residual ash was preferred for high-pectin forage brassicas and non-tannin legumes, but non-sequential methods were acceptable for grasses.

TI Biomass yield and nutritional quality of forage species under long-term irrigation with saline-sodic drainage water: Field evaluation SO ANIMAL FEED SCIENCE AND TECHNOLOGY LA English DT Article DE salt-tolerant forages; drainage water re-use; salinity; selenium; tall wheatgrass ID SALT-TOLERANT FORAGES; REUSE SYSTEMS; SELENIUM; POLIOENCEPHALOMALACIA; ACCUMULATION; SOUTHERN; SULFUR; SOILS AB On the Westside of California's San Joaquin Valley, the discharge of subsurface agricultural drainage water (DW) is subject to strict environmental regulations due to its high selenium (Se) content and potential risks to wildlife. Re-use of sahne-sodic DW to irrigate salt-tolerant forage crops is attractive because it reduces the volume of DW requiring disposal and the land area affected by salinity, while producing forages to satisfy the large demand for animal feed resulting from rapid expansions in dairy and beef cattle operations in this area. The biomass production and nutritional quality of six forages ('Jose' tall wheatgrass, creeping wildrye, alkali sacaton, 'Alta' tall fescue, puccinellia and 'Salado/801S' alfalfa) were evaluated under DW irrigation on a commercial farm near Five Points in Fresno County, California. The forage fields were in their second to fifth year of DW application and most had soil salinities higher than 12 dS/m EC, (electrical conductivity of the saturated soil paste extract). In addition to being very saline, the fields had high levels of boron (B), Se and sodicity [high sodium (Na) relative to calcium (Ca) and magnesium (Mg)]. 'Jose' tall wheatgrass and creeping wildrye had acceptable dry matter (DM) production (7.0 and 11.5 t/ha year) under highly saline conditions of 19 and 13 dS/m EC, respectively. Alfalfa produced 16-20 t/ha year of DM under low salinity conditions of < 7.0 dS/m EC, The forages had estimated metabolizable energy (ME) contents of 7.9-9.9 MJ/kg DM - with the exception of alkali sacaton (6.7 MJ/kg DM) - which would make them acceptable as feeds for beef cattle, sheep and some classes of dairy cattle. Selenium levels varied from 4.4 to 10.7 mg/kg DM in forages that had received 4-5 years of DW application. Forages at the high end of this range could cause Se toxicity in ruminants when used as a sole source of forage, but they could also be used as a Se supplement if fed at a rate of 20-40 g/kg in the Se-deficient areas found along the eastern SJV Saline-sodic DW can be used as a water resource to produce forage suitable for many classes of ruminants, although drainage waters with high levels of Se may present both problems and opportunities.

TI Patterned sequence in the transcriptome of vascular plants SO BMC GENOMICS LA English DT Article ID GENE CONVERSION; DNA-SEQUENCES; SSR-MARKERS; MICROSATELLITES; REPEATS; GENOME; MAIZE; DATABASE; RICE; EVOLUTION AB Background: Microsatellites ( repeated subsequences based on motifs of one to six nucleotides) are widely used as codominant genetic markers because of their frequent polymorphism and relative selective neutrality. Minisatellites are repeats of motifs having seven or more nucleotides. The large number of EST sequences now available in public databases offers an opportunity to compare microsatellite and minisatellite properties and evaluate their evolution over a broad range of plant taxa. Results: Repeated motifs from one to 250 nucleotides long were identified in 6793306 expressed sequence tags ( ESTs) from 88 genera of vascular plants, using a custom data- processing pipeline that allowed limited variation among repeats. The pipeline processed trimmed but otherwise unfiltered sequence and output nonredundant loci of at least 15 nucleotides, with degree of polymorphism and PCR primers wherever possible. Motifs that were an integral multiple of three in length were more abundant and richer in G/ C than other motifs. From 80 to 85% of minisatellite motifs represented repeats within proteins, up to the 228- nucleotide repeat of ubiquitin, but not all of these repeats preserved reading frame. The remaining 15 to 20% of minisatellite motifs were associated with transcribed repetitive elements, e. g., retrotransposons. Relative microsatellite motif frequencies did not correlate tightly to phylogenetic relationship. Evolution of increased microsatellite and EST GC content was evident within the grasses. Microsatellites were less frequent in the transcriptome of genera with large genomes, but there was no evidence for greater dilution of the transcriptome with transposable element transcripts in these genera. Conclusion: The relatively low correlation of microsatellite spectrum to phylogeny suggests that repeat loci evolve more rapidly than the surrounding sequence, although tissue specificity of the different EST libraries is a complicating factor. In- frame motifs are more abundant and higher in GC than frame- shifting motifs, but most EST minisatellite loci appear to represent repeats in translated sequence, regardless of whether reading frame is preserved. Motifs of four to six nucleotides are as polymorphic in EST collections as the commonly used motifs of two and three nucleotides, and they can be exploited as genetic markers with little additional effort.

These uncertainties limit the accuracy of current emission inventories, smoke forecasts, and source apportionments. This study investigates the evolution of gaseous and particulate emission and combustion efficiency by burning wildland fuels in a laboratory combustion facility. Emission factors for carbon dioxide (CO2), carbon monoxide (CO), total hydrocarbon (THC), nitrogen oxides (NOx), PM, light extinction and absorption cross sections, and spectral scattering cross sections specific to flaming and smoldering phases are reported. Emission factors are generally reproducible within +/- 20% during the flaming phase, which, despite its short duration, dominates the carbon emission (mostly in the form of CO2) and the production of light absorption and EC. Higher and more variable emission factors for CO, THC, and PM are found during the smoldering phase, especially for fuels containing substantial moisture. Organic carbon (OC) and EC mass account for a majority (i.e., > 60%) of PM mass; other important elements include potassium, chlorine, and sulfur. Thermal analysis separates the EC into subfractions based on analysis temperature demonstrating that high-temperature EC (EC2; at 700 degrees C) varies from 1% to 70% of PM among biomass burns, compared to 75% in kerosene soot. Despite this, the conversion factor between EC and light absorption emissions is rather consistent across fuels and burns, ranging from 7.8 to 9.6 m(2)/gEC. Findings from this study should be considered in the development of PM and EC emission inventories for visibility and radiative forcing assessments.

We used field data, landscape metrics derived from digital elevation models, and spectral information from remotely sensed imagery to (1) determine recent changes in forest stand structure in relation to historical fire exclusion, (2) quantify the effects of fire exclusion on fuel accumulation patterns, and (3) develop predictive vegetation and fuels maps for our study area. Four vegetation types were identified by cluster analysis including: mesic woodlands, pinyon pine forests, alligator juniper forests, and gray oak forests. Vegetation types varied by elevation, landform type, potential relative radiation (PRR), and spectral signature. Age data suggested that the majority of pines in the Davis Mountains established near 1920,just after the widespread 1916 fire and favorable climatic conditions in 1919. Three fuel types were identified that also varied by elevation, landform type, PRR and spectral characteristics, although the importance of these variables in distinguishing fuel types differed from the environmental variables that discerned the vegetation types. Forest stand densities and fuel accumulations were high in the Davis Mountains, which was probably the result of fire exclusion from grazing activities beginning in the early 1900s. Results from this study will be used to implement forest and fire management activities directed toward ecosystem restoration and maintenance. (c) 2007 Elsevier B.V. All rights reserved.

TI Alteration of the hydrologic cycle due to forest clearing and its consequences for rainforest succession SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE evapotranspiration; secondary shrubland; ecosystem engineers; water table; penman-monteith model; broad-leaved evergreen forest; Chiloe island ID CHILOE ISLAND; ANALYTICAL MODEL; SPECIES COEXISTENCE; INTERCEPTION LOSS; SOUTHERN CHILE; NATIONAL-PARK; DE-CHILOE; VEGETATION; WATER; EVAPOTRANSPIRATION AB Since the 19th century, 41% of the land on Chilo6 Island (41 degrees 50'S, 73 degrees 40'W) in Chile was cleared. Following clearing and burning, much of the converted land remains in sparse shrub cover. We hypothesized that the arrested conversion back to forests may reflect a nearly permanent condition associated with a rise in the water table. To evaluate this possibility we acquired data from a 60-year old evergreen forest and an area in shrub cover to parameterize two hydrologic models; one that accounts for hourly interception losses and predicts net precipitation (Gash model), the other that calculates hourly transpiration from both overstory and understory components as well as evaporation from the soil (a modified Penman-Monteith model). In addition, standpipes were installed to record water table levels over 18 months. The fraction of a total annual precipitation (similar to 2100 mm) transpired by shrub and forest cover differed (8% versus 22%) roughly in proportion to differences in the leaf area index (2.2 versus 5.0). Although whole canopy (stomatal) conductances were similar, the aerodynamic conductance was more than three-fold higher for forests compared with shrub cover (similar to 12 mol m(-2) s(-1) versus 3 mol m(-2) s(-1)). The frequent wetting of tree canopies, combined with an average wind speed of 0.74 m s(-1), resulted in similar to 30% interception losses from forests compared with 1% of annual precipitation lost through this pathway from shrub cover. As a result of these differences, only about half of the precipitation enters the ground under forest cover compared to 90% under shrub cover. This difference in canopy interception losses accounts for a rise in the water table from an average of 45-10 cm. The high water table prevents normal tree regeneration. This condition is stable unless an effort is made to provide an elevated substrate for tree seedlings to become established. (c) 2007 Elsevier B.V. All rights reserved.

TI Effect of stand densities on stand dynamics in white fir (Abies concolor) forests in northeast California, USA SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE growth; logistic model fitting; relative density; stand structure; thinning AB Six white fir trials were established during the last half-century to develop guidelines for managing the existing natural stands across northeastern California. We analyzed data collected from these trials at about 5-year intervals since their installation. Because these trials were independent of each other, the design and treatments varied among the sites. Targeted density treatments were selected based on 40, 55, and 70% of normal basal area from early yield tables at three of the sites. More density treatments were included at the remaining three sites. We found a significant response in growth to different stand densities regardless of site qualities, ages, and stand histories. Periodic annual increment forbasal area and volume varied significantly by periods for all sites except the basal area at one site. Regardless of site quality, thinning from below leaving about 64% of the original measure of basal area did not significantly reduce productivity. If performed early in the life of the stand, such a thinning will reduce the accumulation of flammable materials due to natural self-thinning. A logistic function of periodic annual increment for basal area to relative stand density fits the data well and can be a useful tool for forest manager. (c) 2007 Published by Elsevier B.V.

We compared N fixation and soil N accretion by these shrubs in old-growth ponderosa pine (Pin us ponderosa)-Jeffrey pine (Pinus jeffreyi) stands versus stands that had been harvested 50 years earlier. No differences (alpha = 0.10) in cover, biomass, or percent N derived from fixation by bitterbrush or mahala mat were found between harvested and uncut stands. Approximately 46% of bitterbrush N was derived from symbiotic N fixation as measured by the 15 N natural abundance method. No accurate measure of percent N derived from fixation was attained for mahala mat using this technique due to the absence of a well-matched reference plant. Estimates of total N fixation rates in both stand types were 0.2 kg ha(-1) year(-1) for bitterbrush and 0.3 kg ha(-1) year(-1) or less for mahala mat. No appreciable soil N accretion resulted due to the presence of bitterbrush or mahala mat in either stand type. Nitrogen addition by these shrubs, although small, accounts for 10-60% of annual N input in these dry forest ecosystems. (c) D 2007 Elsevier B.V. All rights reserved.

The objective of this study was to evaluate the cytotoxic and genotoxic potential of the Cr(III) complexes (histidinate, picolinate, and chloride) used as nutrient supplements compared with Cr(VI) dichromate. The cytotoxic and genotoxic effects of the Cr complexes were assessed in human HaCaT keratinocytes. The concentrations of Cr required to decrease cell viability were assessed by determining the ability of a keratinocyte cell line (HaCaT) to reduce tetrazolium dye, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide. DNA damage using the Comet assay and the production of 8-hydroxy-2-deoxyguanosine were also determined with and without hydrogen peroxide-induced stress. The LC50 for human cultured HaCaT keratinocytes was 50 mu M for hexavalent sodium dichromate and more than 120-fold higher for Cr chloride (6 mM) and Cr histidinate (10 mM). For Cr picolinate at saturating concentration (120 mu M) the LC50 was not attained. High Cr(III) concentrations, 250 mu M Cr as Cr chloride and Cr histidinate and 120 mu M Cr picolinate (highest amount soluble in the system), not only did not result in oxidative DNA damage but exhibited protective antioxidant effects when cells were exposed to hydrogen peroxide-induced oxidative stress. These data further support the low toxicity of trivalent Cr complexes used in nutrient supplements. (c) 2007 Published by Elsevier Inc.

Soil aggregate stability is a key indicator of soil structure and is correlated with erodibility and water infiltration capacity. In 2000, we compared soil aggregate stability of a complex of Simona (Loamy, mixed, thermic, shallow Typic Paleorthids) and Harrisburg (Coarseloamy, mixed, thermic, Typic Paleorthids) soils in a Chihuahuan Desert grassland. We examined soil stability at plant and landscape scales by assessing percentage aggregate stability at four sites in two cover classes (plant vs. interspace) located within each of three grass cover and land disturbance classes. To increase measurement sensitivity to changes in soil structure and identify potential early warning indicators for monitoring, we used two different methods for quantifying wet aggregate stability: a laboratory method using a 0.25 mm sieve and a field method using a 1.5 mm sieve. As expected, soil aggregate stability was significantly higher under grass plants than in plant interspaces (44.2 vs. 38.4 for the lab test and 4.4 vs. 3.3 for the field test; P<0.01). The field test showed higher stability in plots with higher grass cover throughout the top 10 mm soil layer, while disturbance level only affected stability at the soil surface. The laboratory test was insensitive to differences in grass cover and disturbance. (C) 2007 Elsevier B.V. All rights reserved.

Little is known about their evolution or expression in lower, vertebrate species. Bioinformatic searches of Zebrafish, Tetraodon, and Fugu genome and other teleost expressed sequence tag databases identified 44 novel gene sequences containing a TNF homology domain. This work reveals the following: 1) teleosts possess orthologs of BAFF, APRIL, EDA, TWEAK, 4-1BBL, Fas ligand, LIGHT, CD40L, RANKL, and possibly TL1A; 2) the BAFF-APRIL subfamily is enriched by a third member, BALM, unique to fish; 3) orthologs of lymphotoxins a and 13 were not clearly identified in teleosts and are substituted by a related ligand, TNF-New; 4) as many as four TRAIL-like genes are present in teleosts, as compared with only one in mammals; and 5) T cell activation ligands OX40L, CD27L, CD30L, and GITRL were not identified in any fish species. Finally, we characterize mRNA expression of TNFSF members CD40L, LIGHT, BALM, APRIL, Fas ligand, RANKL, TRAIL-like, and TNF-New in rainbow trout, Oncorhynchus mykiss, immune and nonimmune tissues. In conclusion, we identified a total of 14 distinct TNFSF members in fishes, indicating expansion of this superfamily before the divergence of bony fish and tetrapods, similar to 360-450 million years ago. Based on these findings, we extend a model of TNFSF evolution and the co-emergence of the vertebrate adaptive immune system.

Here, we investigated the effects of intraperitoneal (ip) administered CpG-ODN on the innate immune functions of chicken heterophils. Our results demonstrated CpG-ODN-dependent priming of chicken heterophil degranulation and oxidative burst. Heterophils from chickens treated with CpG-ODN exhibited significantly higher (p < 0.05) degranulation activity compared to PBS and control ODN (ODN containing no CpG motif) treated groups when stimulated with opsonized Salmonella enterica serovar enteritidis. Similarly, oxidative burst activity, which generates bactericidal reactive oxygen species, was significantly higher (p < 0.05) in heterophils from the CpG-ODN treated group than from PBS and control ODN groups when stimulated with formalin-killed S. enteritidis. The priming effects of CpG-ODN on heterophil immune functions continued at least 4 days post-treatment. In the infection study, newly hatched chickens were treated with CpG-ODN, control ODN or PBS for 24 h then challenged with oral inoculation of S. enteritidis. A significant reduction (p < 0.05) in colonization by S. enteritidis was observed in chickens treated with CpG-ODN. Our study provides evidence that immunostimulatory CpG-ODN potentiates the innate immune responses of heterophils and enhances resistance to infectious pathogens in neonatal chickens.

Schieberle, Peter TI Compound identification: A Journal of agricultural and food chemistry perspective SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article ID DEREPLICATION AB This perspective is designed to summarize the standards that authors of manuscripts submitted to the Journal of Agricultural and Food Chemistry are expected to follow in establishing the structures of either new or unknown compounds identified in the course of a study. It is especially important that the molecular formulas of new compounds be determined by either high-resolution mass spectrometry or combustion analysis. All relevant physical, spectroscopic, and spectrometric data should also be reported, so that other research workers have criteria for comparison with compounds that may be isolated in the future. In the case of flavor and aroma constituents, it is not sufficient to depend upon mass spectrometric identifications based solely on comparison with commercial databases. Mass spectra and retention indices on GC stationary phases of different polarities must be determined and the results compared to data for reference compounds and with commercial standards, when available. If geometric or positional isomers may be present, or for chiral compounds, the retention indices of all isomers or enantiomers must be determined. Odor properties or odor thresholds determined by GC-olfactometry may also serve as appropriate tools for compound identification. Adherence to these standards will ensure that processing of manuscripts proceeds expeditiously and that the high standards of the Journal are maintained. C1 USDA, Albany, CA 94710 USA.

This recognition triggers a series of signals, thereby serving as a molecular switch in regulating defense mechanisms by the plants. To understand the mechanism of action of the barley stem rust resistance gene Rpg1, we investigated the fate of the RPG1 protein in response to infection with the stem rust fungus, Puccinia graminis f. sp. tritici. The investigations revealed that RPG1 disappears to undetectable limits only in the infected tissues in response to avirulent, but not virulent pathotypes. The RPG1 protein disappearance is rapid and appears to be due to specific protein degradation via the proteasome-mediated pathway as indicated by inhibition with the proteasomal inhibitor MG132, but not by other protease inhibitors.

However, it has been relatively difficult to generate comparable responses in non-rodent species. The use of molecular adjuvants may increase the magnitude of these suboptimal responses. In this study, we demonstrate that the co-administration of plasmid-encoded GM-CSF and CD80/CD86 with a novel ESAT-6:CFP10 DNA vaccine against bovine tuberculosis enhances antigen- specific cell-mediated immune responses. ESAT-6:CFP10+GM-CSF+CD80/CD86 DNA vaccinated animals exhibited significant (p<0.01) antigen- specific proliferative responses compared to other DNA vaccinates. Increased expression (p <= 0.05) of CD25 on PBMC from ESAT-6:CFP10+GM-CSF+CD80/CD86 DNA vaccinates was associated with increased proliferation, as compared to control DNA vaccinates. Significant (p<0.05) numbers of ESAT-6:CFP10-specific IFN-gamma producing cells were evident from all ESAT-6:CFP10 DNA vaccinated animals compared to control DNA vaccinates. However, the greatest increase in IFN-gamma producing cells was from animals vaccinated with ESAT-6:CFP10+GM-CSF+CD80/CD86 DNA. In a low-dose aerosol challenge trial, calves vaccinated as neonates with Mycobacterium bovis BCG and ESAT-6:CFP10+GM-CSF+CD80/CD86 DNA exhibited decreased lesion severity in the lung and lung-associated lymph nodes following viruluent M. bovis challenge compared to other vaccinated animals or non-vaccinated controls. These data suggest that a combined vaccine regimen of M. bovis BCG and a candidate ESAT-6:CFP10 DNA vaccine may offer greater protection against tuberculosis in cattle than vaccination with BCG alone.

Surface moisture climatology SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES LA English DT Article ID DROUGHT SEVERITY INDEX; ENERGY FLUXES; SENSED DATA; MODEL; TEMPERATURE; SCALES AB [1] Robust satellite-derived moisture stress indices will be beneficial to operational drought monitoring, both in the United States and globally. Using thermal infrared imagery from the Geostationary Operational Environmental Satellites (GOES) and vegetation information from the Moderate Resolution Imaging Spectrometer (MODIS), a fully automated inverse model of Atmosphere-Land Exchange (ALEXI) has been used to model daily evapotranspiration and surface moisture stress over a 10-km resolution grid covering the continental United States. Examining monthly clear-sky composites for April-October 2002-2004, the ALEXI evaporative stress index (ESI) shows good spatial and temporal correlation with the Palmer drought index but at considerably higher spatial resolution. The ESI also compares well to anomalies in monthly precipitation fields, demonstrating that surface moisture has an identifiable thermal signature that can be detected from space, even under dense vegetation cover. Simple empirical thermal drought indices like the vegetation health index do not account for important forcings on surface temperature, such as available energy and atmospheric conditions, and can therefore generate spurious drought detections under certain circumstances. Surface energy balance inherently incorporates these forcings, constraining ESI response in both energy- and water-limited situations. The surface flux modeling techniques described here have demonstrated skill in identifying areas subject to soil moisture stress on the basis of the thermal land surface signature, without requiring information regarding antecedent rainfall. ALEXI therefore may have potential for operational drought monitoring in countries lacking well-established precipitation measurement networks.

Accurate radiation simulations require some assumption of leaf angle distribution to compute transmissivity, reflection and scattering of radiation. The ellipsoidal leaf angle density function can very closely approximate real plant canopies but requires complex integrations for different combinations of leaf area index, incident radiation angle, and density function. This paper presents close approximations (R-2 > 0.99) to compute the transmissivity and scattering functions for elliptical leaf angle distributions that can be more easily implemented into simulation models.

The current studies were undertaken to determine whether inflammatory responses are activated in the vasculature of mice with diet-induced obesity, and if so, whether Toll-Like Receptor-4 (TLR4), a key mediator of innate immunity, contributes to these responses. Mice lacking TLR4 (TLR4(-/-)) and wild-type (WT) controls were fed either a low fat (LF) control diet or a diet high in saturated fat (HF) for 8 weeks. In response to HF feeding, both genotypes displayed similar increases of body weight, body fat content, and serum insulin and free fatty acid (FFA) levels compared with mice on a LF diet. In lysates of thoracic aorta from WT mice maintained on a HF diet, markers of vascular inflammation both upstream (IKK beta activity) and downstream of the transcriptional regulator, NF-kappa B (ICAM protein and IL-6 mRNA expression), were increased and this effect was associated with cellular insulin resistance and impaired insulin stimulation of eNOS. In contrast, vascular inflammation and impaired insulin responsiveness were not evident in aortic samples taken from TLR4 (-/-) mice fed the same HF diet, despite comparable increases of body fat mass. Incubation of either aortic explants from WT mice or cultured human microvascular endothelial cells with the saturated FFA, palmitate (100 mu mol/ L), similarly activated IKK beta, inhibited insulin signal transduction and blocked insulin-stimulated NO production. Each of these effects was subsequently shown to be dependent on both TLR4 and NF-kappa B activation. These findings identify the TLR4 signaling pathway as a key mediator of the deleterious effects of palmitate on endothelial NO signaling, and are the first to document a key role for TLR4 in the mechanism whereby diet-induced obesity induces vascular inflammation and insulin resistance.

To characterize a bacterium associated with epitheliocystis in cultured charr, gills were sampled for histopathologic examination, conventional and immunoelectron microscopy, in situ hybridization, 16S ribosomal DNA (rDNA) amplification, sequence analysis and phylogenetic inference. Sampling was conducted at the Freshwater Institute (Shepherdstown, West Virginia, USA) during outbreaks of epitheliocystis in April and May 2002. Granular, basophilic, cytoplasmic inclusions in charr gill were shown to stain with Macchiavello, Lendrum's phloxine-tartrazine and Gimenez histochemical techniques. Ultrastructurally, inclusions were membrane-bound and contained round to elongate reticulate bodies that were immunoreactive to an antibody against chlamydial lipopolysaccharide, suggesting the presence of similar epitopes. DNA extracted from gills supported amplification of the most polymorphic and phylogenetically relevant region of the 16S rRNA gene, which had 97 to 100 % identity with several uncultured clinical Neochlamydia spp. (order Chlamydiales) Clones WB13 (AY225593.1) and WB258 (AY225594.1). Sequence-specific riboprobes localized to inclusions during in situ hybridization experiments. Taxonomic affiliation was inferred by distance- and parsimony-based phylogenetic analyses of the 16S sequence, which branched with Neochlamydia hartmannellae in the order Chlamydiales with high confidence. This is the first molecular characterization of a chlamydia associated with epitheliocystis in Arctic charr and the fourth Neochlamydia spp. sequence to be associated with epitheliocystis. Presence of a clinical neochlamydial sequence, first identified from a cat, in Arctic charr suggests a possible mammalian and piscine host range for some environmental chlamydiae.

Deer were treated twice in 1997; given a booster in 1998, with six being revaccinated in September 2000. Granulomas were found at injection sites of most deer, even 2 years post-treatment. Eosinophilic oophoritis occurred in 6 of 8 (75%) deer vaccinated in 1998, and 3 of 6 (50%) revaccinated in 2000. The 2000 revaccinates without oophoritis, had significantly fewer normal secondary follicles than control females (P=0.03), and deer in the 1998 treatment group (P=0.04). PZP immunocontraceptive vaccine elicited ovarian pathologies in deer similar to those observed in other species. (C) 2007 Elsevier Ltd. All rights reserved.

Development of inflorescences and florets as influenced by bulb storage temperature was studied using scanning electron microscopy (SEM). Three experiments were carried out: bulbs of 5.2 cm circumference (circum.) were treated at either 10, 16, 22, or 28 degrees C for a 6-week period, followed by other temperatures for a total of 18 weeks (Experiment 1); bulbs of two sizes, 8.1 and 12.8 cm in circum. received 6 weeks of 30 degrees C, followed by 3 and 6 weeks of 7, 10, 13, 16, 19, 22, 25 and 30 degrees C (Experiment 2); bulbs of two sizes, 5.7 and 6.5 cm in circum. were dried at 20 degrees C for a week and were potted after storing for 6 weeks at 30 degrees C (30 degrees C/6W) followed by either storage at 20 degrees C for 4 or 8 weeks (20 degrees C/4W or 20 degrees C/8W) and finally at 10 degrees C/4W or 20 degrees C/8W (Experiment 3). Development of inflorescences and florets were studied using SEM (Experiment 1). Bulb sizes of 'Chesapeake Starlight' (Experiments 2 and 3) did not affect flowering. The shoot apex of the bulb is vegetative at harvest and bulbs should be stored dry at 28-30 degrees C for 6 weeks for rapid inflorescence development. When root primordia were clearly visible at the end of the 20 C treatment, the scape of the first inflorescence is clearly formed, and bulbs are then treated at 10 degrees C. When bulbs were treated at 28 degrees C during the first 6 weeks (week 0-6), flowering accelerated. Flowering was also accelerated and only one inflorescence was produced from the center when bulbs were stored at 10 degrees C/6W during the second and third 6 weeks (weeks 7-12 and weeks 13-18). A sequential treatment of 30 degrees C/6W-10 degrees C/6W10 degrees C/6W ensured a longer flower stem and accelerated flowering of the first inflorescence, and this was verified by SEM. Flower stem length increased significantly and only one inflorescence was produced from the center when bulbs received 30 degrees C/6W-20 degrees C/4W-10 degrees C/8W as compared to bulbs that received 30 degrees C/6W-20 degrees C/4W-10 degrees C/4W. To produce two or more inflorescences per bulb, we recommend treating bulbs at 10 degrees C/3-4W or 13 degrees C/3W. Descriptions of the development of the first and second inflorescence and of a single flower using SEM will be useful to document the development of inflorescence and flowers during bulb storage and to further develop precise treatment temperatures and durations to shorten the pre-treatment period of bulbs after harvest.

However, little is know about its genome and genes involved in the biology and pathogenicity of the pathogen. We initiated the functional genomic research of the fungus by constructing a full-length cDNA and determined functions of the first group of genes by sequence comparison of cDNA clones to genes reported in other fungi. Results: A full-length cDNA library, consisting of 42,240 clones with an average cDNA insert of 1.9 kb, was constructed using urediniospores of race PST-78 of P. striiformis f. sp. tritici. From 196 sequenced cDNA clones, we determined functions of 73 clones (37.2%). In addition, 36 clones (18.4%) had significant homology to hypothetical proteins, 37 clones (18.9%) had some homology to genes in other fungi, and the remaining 50 clones (25.5%) did not produce any hits. From the 73 clones with functions, we identified 51 different genes encoding protein products that are involved in amino acid metabolism, cell defense, cell cycle, cell signaling, cell structure and growth, energy cycle, lipid and nucleotide metabolism, protein modification, ribosomal protein complex, sugar metabolism, transcription factor, transport metabolism, and virulence/infection. Conclusion: The full-length cDNA library is useful in identifying functional genes of P. striiformis. C1 USDA ARS, Wheat Genet Qual Physiol & Dis Res Unit, Pullman, WA 99164 USA.

Methods: A cross sectional evaluation was performed on 58 older men (n=27) and women (n=31) (74.2 +/- 0.9 years). Knee and hip (leg press) and knee extensor power were evaluated on pneumatic and isokinetic resistance equipment. Incremental single attempt power (IP) testing utilized a single attempt at attaining maximum power at each of six external resistances and was compared to multiple attempt pneumatic power (MP) testing determined by the highest of 5 attempts at achieving maximum power at two set resistances and also with power determined by isokinetic dynamometry. Results: Leg press extension MP yielded significantly greater power than IP at both low (mean =225.3 +/- 11.85 and 183.9 +/- 11.52 watts respectively, p < 0.001) and high (mean =249.7 +/- 15.25 and 201.7 +/- 13.18 watts respectively, p < 0.001) external resistances. Knee extension MP also produced significantly greater power when compared to IP at low (mean=82.4 +/- 4.45 and 69.7 +/- 4.28 watts respectively, p < 0.001) and high (mean=93.7 6.3 and 83.2 +/- 5.93 watts respectively, p < 0.001) external resistances. MP testing exhibited excellent reliability at both low (leg press extension: Intra Class Correlation (ICC)=0.93, knee extension: ICC=0.87) and high (Leg press extension: ICC=0.85, Knee Extension: ICC=0.91) external resistances, MP knee extension at 70% 1 RM also showed good agreement with average isokinetic power (R-2=0.636). Conclusions: These findings support the reliability and concurrent validity of MP for the evaluation of muscle power in older individuals.

Natural wetlands in China suffered great loss and degradation (e.g., 23.0% freshwater swamps, 51.2% costal wetlands) because of the wetland reclamation during China's long history of civilization, and the population pressure and the misguided policies over the last 50 years. Recently, with an improved understanding that healthy wetland ecosystems play a vital role in her sustainable economic development, China started major efforts in wetland conservation, as signified by the policy to return reclaimed croplands to wetlands, the funding of billions of dollars to restore degraded wetlands, and the national plan to place 90% of natural wetlands under protection by 2030. This paper describes the current status of the natural wetlands in China, reviews past problems, and discusses current efforts and future challenges in protecting China's natural wetlands.

Concerns remain that systematic reviews of nutrition topics pose several unique challenges. We present a successful collaboration to systematically review the health effects of a common nutrient, n-3 (or omega-3) fatty acids, across a wide range of clinical conditions. More generally, we discuss the challenges faced and the lessons learned during the review, the benefits of systematic review of nutritional topics, and recommendations for conducting and reviewing nutrition-related studies. Through a structured but flexible process, 3 Evidence-based Practice Centers in the Agency for Healthcare Research and Quality program produced I I reports on a wide range of n-3 fatty acid-related topics. An important resource has been created, through which nutrition and dietetics researchers, clinical dietitians and nutritionists, clinicians, and the general public can understand the state of the science. The process identified challenges and problems in evaluating the health effects of n-3 fatty acid consumption, highlighted challenges to reviewing the human nutrition literature, and yielded recommendations for future research. The goals of these systematic reviews, the processes that were used, the benefits and limitations of the collaboration, and the conclusions of the reviews, including recommendations for future research, are summarized here.

Objective: The study objective was to test sociodemographic, metabolic, and behavioral predictors of 1-y weight gains in a large cohort of Hispanic children studied longitudinally. Design: Subjects (n = 879) were siblings from 319 Hispanic families enrolled in the Viva la Familia Study. Families were required to have at least one overweight child aged 4 -19 y. One-year changes in weight and body composition by dual-energy X-ray absorptiometry were measured. Data were from parental interviews, birth certificates, multiple-pass 24-h dietary recalls, 3-d accelerometry, 24-h respiration calorimetry, measurements of eating in the absence of hunger, and measurement of fasting blood biochemistry indexes by radioimmunoassay. Generalized estimating equations and principal component analysis were applied. Results: Weight gain increased with age (P = 0.001), peaking at approximate to 10 y ofage in girls and approximate to 11 y ofage in boys. Mean (+/- SD) weight gain was significantly higher in overweight (7.5 +/- 3.7 kg/y) than in nonoverweight (4.4 +/- 2.4 kg/y) children and in boys than in girls. When adjusted for age, age squared, sex, and Tanner stage, the final model indicated a child's body mass index (BMI; kg/m(2)) status, maternal BMI, energy expenditure (total energy expenditure, basal metabolic rate, and sleeping metabolic rate), and fasting blood biochemistry indexes (total triiodothyronine, insulin, leptin, and ghrelin) as independent, positive predictors of weight gain (P = 0.01-0.001). Conclusion: Knowledge of the metabolic and behavioral predictors of weight gain in Hispanic children will inform prevention and treatment efforts to address this serious public health problem in the United States.

TI Zinc deficiency depresses p21 gene expression: inhibition of cell cycle progression is independent of the decrease in p21 protein level in HepG2 cells SO AMERICAN JOURNAL OF PHYSIOLOGY-CELL PHYSIOLOGY LA English DT Article DE p21 mRNA; p21 promoter accessibility; zinc status; human hepatoblastoma cells ID P21(WAF1/CIP1) TRANSCRIPTION; CASPASE-3 ACTIVITY; DNA-REPLICATION; P53; KINASE; PROMOTER; ACTIVATION; APOPTOSIS; SP1; UBIQUITINATION AB The influence of zinc status on p21 gene expression was examined in human hepatoblastoma (HepG2) cells. Cells were cultured for one passage in a basal medium depleted of zinc to induce severely zinc-deficient (ZD) cells or in basal medium supplemented with 0.4, 4.0, 16, or 32 mu M zinc to represent mild zinc deficiency (ZD0.4), the amount of zinc in most normal media (ZN), the normal human plasma zinc level (zinc-adequate; ZA), or the high end of plasma zinc attainable by oral supplementation (ZS), respectively. In ZD and ZD0.4 cells, the nuclear p21 protein level, mRNA abundance, and promoter activity were reduced to 40, 70, and 65%, respectively, of ZN cells. However, p21 protein and mRNA levels, as well as p21 promoter activity, were not altered in ZA and ZS cells compared with ZN cells. Moreover, the amounts of acetylated histone-4 associated with the proximal and distal p21 promoter regions, as a measure of p21 promoter accessibility, were decreased in ZD (73 and 64%, respectively) and ZD0.4 (82 and 77%, respectively) cells compared with ZN cells (100 and 100%, respectively). Thus multiple lines of evidence indicate that the transcriptional process of p21 is downregulated by depressed zinc status in HepG2 cells. Furthermore, the transfection of 5 mu g of plasmid cytomegalovirus-p21 plasmid, which constitutively expressed p21, was able to normalize the reduction in p21 protein level and cyclin D1-cdk4 complex activity but not the inhibition of cell growth and G1/S cell cycle progression in ZD cells.

To date, several competitive exclusion products have been developed from Such studies as prophylactic treatment against pathogenic bacteria. A continuous-flow chemostat model of a feral pig was developed using inocula from the cecal contents of a wild boar caught in East Texas. Several strains of antibiotic-sensitive bacteria were isolated including Bacteroides, Lactobacillus, Enterococcus and Clostridium sp. This study reports on the characterization of a multidrug-resistant Clostridum hathewayi strain that was isolated from this feral pig's cecal contents maintained in a continuous-flow chemostat system showing high resistance to carbapenems and macrolides (including the growth promoter tylosin). Clostridium hathewayi has been documented to be pathogenic to both humans and animals. Feral pigs may be an important source of pathogenic and antibiotic resistant bacteria and may pose potential risk to domestic species. Further work is needed to elucidate the prevalence of these reservoirs and assess the contribution these may play in the spread of disease and resistance. Published by Elsevier Ltd.

TI Genetic relationships between feral cattle from Chirikof Island, Alaska and other breeds SO ANIMAL GENETICS LA English DT Article DE cattle; genetic distance; genetic variation ID POPULATION-STRUCTURE; CONSERVATION; MARKERS AB The origin of cattle on Chirikof Island, off the coast of Alaska, is not well documented. We assessed genetic differentiation of cattle isolated on Chirikof Island from several breeds commonly used for commercial production in North America including breeds popularly believed to have contributed to the Chirikof Island population. A set of 34 microsatellite loci was used to genotype Angus, Charolais, Hereford, Highland, Limousin, Red Angus, Salers, Shorthorn, Simmental, Tarentaise and Texas Longhorn cattle sampled from North America and the Chirikof Island population. Resulting F-ST statistics for these loci ranged from 0.06 to 0.22 and on average, 14% of total genetic variation was between breeds. Whether population structure was modelled as a bifurcating tree or genetic network, Chirikof Island cattle appeared to be unique and strongly differentiated relative to the other breeds that were sampled. Bayesian clustering for multiple-locus assignment to genetic groups indicated low levels of admixture in the Chirikof Island population. Thus, the Chirikof Island population may be a novel genetic resource of some importance for conservation and industry. C1 USDA ARS, Miles City, MT 59301 USA.

TI Single nucleotide polymorphisms for pig identification and parentage exclusion SO ANIMAL GENETICS LA English DT Article DE identification; parentage; pig; single nucleotide polymorphism ID ANIMAL IDENTIFICATION; MARKERS; PROBABILITY; NUMBER AB Single nucleotide polymorphisms (SNPs) have become an important type of marker for commercial diagnostic and parentage genotyping applications as automated genotyping systems have been developed that yield accurate genotypes. Unfortunately, allele frequencies for public SNP markers in commercial pig populations have not been available. To fulfil this need, SNP markers previously mapped in the USMARC swine reference population were tested in a panel of 155 boars that were representative of US purebred Duroc, Hampshire, Landrace and Yorkshire populations. Multiplex assay groups of 5-7 SNP assays/group were designed and genotypes were determined using Sequenom's MASSARRAY((R)) system. Of 80 SNPs that were evaluated, 60 SNPs with minor allele frequencies > 0.15 were selected for the final panel of markers. Overall identity power across breeds was 4.6 x 10(-23), but within-breed values ranged from 4.3 x 10(-14) (Hampshire) to 2.6 x 10(-22) (Yorkshire). Parentage exclusion probability with only one sampled parent was 0.9974 (all data) and ranged from 0.9594 (Hampshire) to 0.9963 (Yorkshire) within breeds. Sire exclusion probability when the dam's genotype was known was 0.99998 (all data) and ranged from 0.99868 (Hampshire) to 0.99997 (Yorkshire) within breeds. Power of exclusion was compared between the 60 SNP and 10 microsatellite markers. The parental exclusion probabilities for SNP and microsatellite marker panels were similar, but the SNP panel was much more sensitive for individual identification. This panel of SNP markers is theoretically sufficient for individual identification of any pig in the world and is publicly available. C1 USDA ARS, US Meat Anim Res Ctr, Clay Ctr, NE 68933 USA.

Probes were selected that target housekeeping and virulence-associated genes in both Arcobacter butzleri and thermotolerant C. ampylobacter jejuni and Campylobacter coli. These microarrays showed a high level of probe specificity; the signal intensities detected forA. butzleti, C. coli, or C. jejuni probes were at least 10-fold higher than the background levels. Specific identification of A. butzleri, C. coli, and C. jejuni was achieved without the need for a PCR amplification step. By adapting an isolation method that employed membrane filtration and selective media, C. jejuni isolates were recovered from package liquid from whole chicken carcasses prior to enrichment. Increasing the time of enrichment resulted in the isolation of A. butzleri and increased the recovery of C. jejuni. C. jejuni isolates were further classified by using an additional subset of probes targeting the lipooligosaccharide (LOS) biosynthesis locus. Our results demonstrated that most of the C. jejuni isolates likely possess class B, C, or H LOS. Validation experiments demonstrated that the DNA microarray had a detection sensitivity threshold of approximately 10,000 C. jejuni cells. Interestingly, the use of C. jejuni sequence-specific primers to label genomic DNA improved the sensitivity of this DNA microarray for detection of C. jejuni in whole chicken carcass samples. C. jejuni was efficiently detected directly both in package liquid from whole chicken carcasses and in enrichment broths.

The aim of this study was to compare the behavior and performance of sows that killed piglets (CR) to those that did not (NC) inside a farrowing but within the first 72 h after parturition. A total of 336 sows and their litters were used for comparisons. CR sows had more (P < 0.01) piglets bom/litter and born alive/litter than NC sows. Mortality was higher (P < 0.01) for CR sows, with most piglet mortality in the first 72 h and there was a trend (P = 0.06) for CR sows to wean fewer piglets/litter than NC sows (7.8 +/- 0.20 versus 8.4 +/- 0.26), respectively. Behaviors were collected by time-lapse video on 20 sows, 10 from each group. Four sow postures: walking, standing, sitting and lying; four sow behaviors: pawing, rooting, nursing interval and nursing duration; and one sow location: out of but were recorded. NC sows had a longer (P = 0.03) parturition compared to CR sows. Time (min) spent outside the farrowing but did not differ between groups over the first 2 days, but on day 3 NC sows spent more (P = 0.01) time outside of the farrowing but (20.2 +/- 4.7) compared to CR sows (40.4 +/- 4.8). NC sows spent more time pawing (P < 0.01) than CR sows (5.2 +/- 0.41 min versus 1.7 +/- 0.38 min) but no differences were found for all other behaviors (P > 0.05). There were no (P > 0.05) group differences for sow lying postures. One hour prior to piglet mortality 62.5% of CR sows moved from lying sternal to lying lateral, 25% moved from lying lateral to lying sternal and 12.5% of CR sows went from standing to lying lateral. In conclusion, CR sows spent more time inside the farrowing but on day 3, spent more time lying on their sternum prior to crushing a piglet and the behavioral sequence associated with crushing piglets was a shift in lying postures rather than a transition from sitting or standing to lying.

Mycobacterium cells were detected along the total root length for four of these isolates. These PAH-degrading mycobacterium strains had hydrophilic cell surfaces, whereas one strain, MCS, that was hydrophobic had reduced association along the root length with no cells being detected from the root tips. The root-tip-competent strain, KMS, was competitive for its root association in the presence of the root-colonizing pseudomonad, Pseudomonas putida KT2440. All mycobacterium strains utilized simple sugars (fructose, glucose) and the trisaccharide 6-kestose, present in barley root washes, for planktonic growth, but they differed in their potential for biofilm formation under in vitro conditions. Mineralization of pyrene by the KMS strain occurred when the components in the barley root wash were amended with labeled pyrene suggesting to us that mineralization could occur in plant rhizospheres containing such mycobacterium strains.

The deduced protein had a molecular mass of about 58 kDa, and analysis of its amino acid sequence revealed significant homology and conservation of different catalytic residues with alpha-L-arabinofuranosidases belonging to family 51 of the glycoside hydrolases. A histidine tag was introduced at the N-terminal end of AbfATK4, and the recombinant protein was expressed in Escherichia coli BL21, under control of isopropyl-beta-D-thiogalactopyranoside-inducible T7 promoter. The enzyme was purified by nickel affinity chromatography. The molecular mass of the native protein, as determined by gel filtration, was about 236 kDa, suggesting a homotetrameric structure. AbfATK4 was active at a broad pH range (pH 5.0-10.0) and at a broad temperature range (40-85 degrees C), and it had an optimum pH of 6.0 and an optimum temperature of 75-80 degrees C. The enzyme was more thermostable than previously described arabinofuranosidases and did not lose any activity after 48 h incubation at 70 degrees C. The protein exhibited a high level of activity with p-nitrophenyl-alpha-L-arabinofuranoside, with apparent K(m) and V(max) values of 0.17 mM and 5 88.2 U/mg, respectively AbfATK4 also exhibited a low level of activity with p-nitrophenyl-beta-D-xylopyranoside, with apparent K(m) and V(max) values of 1.57 mM and 151.5 U/mg, respectively. AbfATK4 released L-arabinose only from arabinan and arabinooligosaccharides. No endoarabinanase activity was detected. These findings suggest that AbfATK4 is an exo-acting enzyme.

The first experiment compared plant response in both soils to a mix of AMF species (Glomus mosseae, Glomus intraradices, and Scutellospora calospora) isolated from Jory soil. Results showed that vine growth was heavily dependent on AMF in Jory soil, but inoculated and non-inoculated vines grew equally well in Chehalis soil. The increase in plant dry mass (274%) of 'Pinot noir' grown with AMF in Jory soil was primarily due to enhanced P uptake (833% increase). Uptake of most other nutrients was also enhanced by AMF in Jory soil. Sulfur was the only nutrient taken up in greater quantity by AMF vines in Chehalis soil. Root colonization by AMF was lower in Chehalis soil compared to Jory soil. A second experiment compared plant response in both soils to either native or normative G. mosseae isolated from each respective soil type. Vine growth in Chehalis soil was not affected by either G. mosseae isolate, although both isolates increased P and Zn uptake and the native isolate enhanced Cu and S uptake by 'Pinot noir'. Both G. Mosseae isolates enhanced vine growth in Jory soil, primarily due to improved P uptake; however, the normative isolate of G. mosseae colonized roots to a greater degree and was more effective in promoting growth and nutrient uptake than the native isolate. Results from these experiments show that 'Pinot noir' is dependent on AMF to obtain enough P for normal growth in red-hill soils, while growth in valley soils is not dependent on AMF, even though P uptake can be improved by AMF in this soil. Native or normative G. mosseae isolates performed equally well in promoting P uptake in Chehalis soil, however, the Chehalis soil fungus outperformed the Jory soil fungus in promoting P uptake in Jory soil and Cu and S uptake in both soils.

Genotyping costs are considerable; therefore, we developed a single-step method of co-amplifying twelve microsatellites in two hexaplex reactions to reduce costs and improve efficiency. The protocol is explicitly described to ensure reproducible results. We applied the protocol to samples analyzed at the National Center for Cool and Coldwater Aquaculture (NCCCWA) with previously reported marker sets for a comparison of results. Each marker within the multiplex system was evaluated for duplication, null alleles, physical linkage, and probability of genotyping errors. Data from four of the 12 markers were excluded from parental analysis based on these criteria. Parental assignments were compared to those of a previous study that used five independently amplified microsatellites. Percentages of progeny assigned to parents were higher using the subset of eight markers from the multiplex system than with five markers used in the previous study (98% vs. 92%). Through multiplexing, additional markers were used to improve parental allocation while also improving efficiency by reducing the number of required PCR reactions and genotyping runs. We evaluated our methods further through estimation of F-statistics, pairwise genetic distances, and cluster analysis among brood-years at the NCCCWA facility. These measures were compared to estimates from nine independently amplified microsatellites used in a previous study. The F-st results calculated between brood-years show similar values of genetic differentiation using both marker sets. Estimates of individual pairwise genetic distances were used for constructing neighbor-joining trees. Both marker sets yielded trees that show similar subpopulation structuring and agreed with results from a model-based cluster analysis and available pedigree information. These approaches for detecting population substructure and admixture portions within individuals are particularly useful for new breeding programs where the founders' relatedness is unknown.

TI Fenofibrate effect on triglyceride and postprandial response of apolipoprotein A5 variants - The GOLDN study SO ARTERIOSCLEROSIS THROMBOSIS AND VASCULAR BIOLOGY LA English DT Article DE aPOA5; fenofibrate; triglyceride lowering; increasing HDL-C; gene-drug interaction ID ACTIVATED RECEPTOR-ALPHA; CORONARY-ARTERY-DISEASE; PLASMA TRIGLYCERIDE; RICH LIPOPROTEINS; DENSITY-LIPOPROTEIN; APOA5 LOCUS; FATTY-ACIDS; AV GENE; POLYMORPHISM; RISK AB Objective-Apolipoprotein A5 (APOA5) is a key determinant of plasma triglyceride (TG) concentrations. Genetic variation at the APOA5 locus could be responsible for some of the observed differences in response to fenofibrate therapy. Methods and Results-We examined the association between tag SNPs (-1131T>C and 56C>G) at APOA5 and TG and HDL-C response to fenofibrate and a postprandial lipid challenge in 791 men and women participating in the GOLDN study. After 3-week drug treatment, APOA5 56G carriers displayed significant decrease in TG (P=0.006), and increase in HDL-C (P=0.002) levels relative to their basal values in the fasting state when compared with noncarriers (a TG reduction of -35.8 +/- 2.8% versus -27.9 +/- 0.9% and a HDL-C increase of 11.8 +/- 1.3% versus 6.9 +/- 0.5%, respectively). In the postprandial lipemia after a fat load, the 56G carriers showed a significant decrease in the area under curve for TG and increase for HDL-C than the noncarriers. These diverse beneficial responses of 56G carriers to fenofibrate were further characterized by a higher increase in large LDL-C concentrations and LDL size. On the other hand, subjects with different APOA5-1131T>C genotypes showed no significant response to fenofibrate intervention. Conclusion-This study suggests that the APOA5 56G carriers benefited more from the fenofibrate treatment than noncarriers in lowering plasma TG and increasing HDL-C levels.

For up to nine seed species, the effects of seed size ( cm 3), mass (mg), density (mg/cm(3)) and coat strength (MPa) on the damage inflicted by three post-dispersal granivores (Harpalus pensylvanicus, Anisodactylus sanctaecrucis, and Gryllus pennsylvanicus) were evaluated. Seed destruction rates by G. pennsylvanicus were statistically unrelated to the size and toughness of the seeds. Seed densities significantly affected their destruction by A. sanctaecrucis and H. pensylvanicus, as did seed size, mass, and strength in H. pensylvanicus under choice conditions. The carabid beetles destroyed more of the small, denser seeds with stronger seed coats. The results show that different granivores are able to distinguish the structural strength and physical density of seeds as well as seed size. The relative ability of granivores to detect these seed characteristics offers a way in which diverse communities of post-dispersal insect granivores can persist within a single habitat. The authors redefine how the strength of biological structures should be evaluated in ecological studies, using guidelines commonplace in the field of engineering.

We used a form of multicriteria analysis (the analytic hierarchy process, AHP) to record and analyse the knowledge and opinions of 31 Australian ecologists on those ecosystem attributes considered most important as biodiversity surrogates, and those that were considered most feasible to assess. From a pool of 13 landscape context attributes and 62 vegetation condition attributes, practical and defensible attribute sets were identified based on AHP importance and feasibility weights and associated statistical analyses. Experts considered that, on average, landscape context attributes should contribute approximately one-third (0.36) to an assessment of within-vegetation-type species-level biodiversity status, and vegetation condition attributes should contribute the remaining two-thirds (0.64). Our analyses did, however, find a correlation between these importance weights and the spatial scales at which experts worked. The landscape context attributes: patch size, distance to nearest large patch, and connectivity were considered significantly more important than other attributes; however, connectivity received a significantly lower feasibility weight. A minimum set of 11 compositional, structural and functional vegetation condition attributes were identified: richness of native trees; cover of native trees, shrubs and perennial grasses; cover of exotic shrubs, perennial grasses, legumes and forbs; cover of organic litter; recruitment of native tree/shrub saplings; native tree health; and evidence of grazing. We compare our minimum sets of attributes with other published sets, and briefly discuss the issues surrounding the incorporation of attributes into natural variability benchmarks from which indices of terrestrial species-level biodiversity status of woodland and forest patches can be determined.

Certain dithiocarbamate pesticides such as tetramethyl thimam disulfide (thiram) have been shown to induce the disease in chickens. Because many different carbamate and thiocarbamate chemicals are used in a number of agricultural, industrial, and household applications, the objective of this study was to determine whether all chemicals of these categories induce TD and whether there is a concentration-dependent relationship between the ingestion of these chemicals and the incidences and the severity of the disease. Week-old broiler chicks were fed diets containing thiram or other assorted carbamate and thiocarbamate pesticides mixed in feed for 24-48 hr between ages 8 and 10 days. The birds were killed on day 15 and the proximal tibial and tarsometatarsal growth plates were evaluated for the presence and severity of TD lesions. TD was distinguished by broadening of growth plates; upon histologic exam chondrocytes appeared to be shrunken and dead. When compared by including equimolar concentrations of these chemicals in the feed, the dithiocarbamates with more than two sulfide groups, such as disulfiram, ferbam, thiram, and ziram were potent inducers of TD, whereas those with two sulfides to no sulfide group appeared ineffective at inducing TD. Both thiram and ferbam also reduced the bird's body weights. Thiram increased the incidence and the severity of the disease, denoted by TD index, in a dose-dependent manner. These results suggest that inadvertent contamination of feed or litter with some of these or similar chemicals may cause leg problems in poultry.

To elucidate the possibility that cereal fructans may stabilize cellular membranes during dehydration, we used liposomes as a model system and isolated tructans from oat (Avena sativa) and rye (Secale cereale). Fructans were fractionated by preparative size exclusion chromatography into five defined size classes (degree of polymerization (DP) 3 to 7) and two size classes containing high DP fructans (DP > 7 short and long). They were characterized by high performance liquid chromatography (HPLC) and matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). The effects of the fructans on liposome stability during drying and rehydration were assessed as the ability of the sugars to prevent leakage of a soluble marker from liposomes and liposome fusion. Both species contain highly complex mixtures of fructans, with a DP up to 17. The two DP > 7 fractions from both species were unable to protect liposomes, while the fractions containing smaller fructans were protective to different degrees. Protection showed an optimum at DP 4 and the DP 3, 4, and 5 fractions from oat were more protective than all other fractions from both species. In addition, we found evidence for synergistic effects in membrane stabilization in mixtures of low DP with DP > 7 fructans. The data indicate that cereal fructans have the ability to stabilize membranes under stress conditions and that there are size and species dependent differences between the fructans. In addition, mixtures of fructans, as they occur in living cells may have protective properties that differ significantly from those of the purified fractions. (c) 2007 Elsevier B.V.

The selected mealybug species represent major subfamilies and tribes of Pseudococcidae. Except for F. virgata, all mealybug species induced examinations by Anagyrus sp. nov. nr. sinope and L. dactylopii. Anagyrus sp. nov. nr. sinope was specific to P. madeirensis, which was the only mealybug species selected for oviposition and suitable for complete development of the parasitoid. No encapsulation of Anagyrus sp. nov. nr. sinope in P. madeirensis was observed. Leptomastix dactylopii accepted multiple species for oviposition, with the ranking of species preference as P. citri > P. viburni > P. longispinus > P. solani > P. madeirensis. Only P. citri, P. longispinus and P. viburni supported the development of L. dactylopii. Parasitoids developing in P. longispinus and P. viburni suffered from high encapsulation rates, while no encapsulation was observed when developing in P. citri. The results of this study suggest that Anagyrus sp. nov. nr. sinope is highly host specific. Leptomastix dactylopii, on the other hand, has a wider host range. The use of Anagyrus sp. nov. nr. sinope in a mealybug biological control program is limited to P. madeirensis and L. dactylopii to P. citri. The results presented in this study also lead us to question the accuracy of the reported host range of L. dactylopii, which include all six mealybug species tested.

Rydb. ex A.W. Hill (hemp sesbania) was effectively controlled in soybean [Glycine max (L.) Merr.] field test plots over a 2-year testing period (1995-1996) with microsclerotia of the bioherbicidal fungus, Colletotrichum truncatum, formulated in wheat gluten-kaolin granules called 'Pesta'. Weed control averaged 84% and 88%, respectively, in plots treated pre-plant incorporated (PPI) at 'Pesta' rates of 168 or 336 kg ha(-1), and 71% and 78%, respectively, in plots treated pre-emergence (PE) at 'Pesta' rates of 168 or 336 kg ha(-1) over the testing period. Post-emergence (POE) control averaged 30% and 50%, respectively, for the 168 and 336 kg ha(-1) treatments, and was significantly less effective than either PE or PPI treatments. Although pathogenesis and mortality occurred in hemp sesbania tissues, satisfactory weed control was not achieved in plots treated at rates of 17 or 84 kg ha(-1) with any of the application methods. Soybean yields were significantly greater in test plots treated PPI or PE, as compared to yields from test plots treated either POE, with inert 'Pesta' granules, or from untreated controls. Microsclerotia formulated in 'Pesta' granules exhibited excellent shelf-life, retaining high viability after storage for 10 years at 4 degrees C. These results suggest that microsclerotia of C. truncatum formulated in 'Pesta' granules offers an effective method for controlling this important weed and preserving the activity of this bioherbicide.

TI Elton's hypothesis revisited: an experimental test using cogongrass SO BIOLOGICAL INVASIONS LA English DT Article DE biodiversity; cogongrass; exotic; Functional Diversity; Imperata cylindrica; invasibility ID PLANT-SPECIES-RICHNESS; IMPERATA-CYLINDRICA; COMMUNITY INVASIBILITY; BIOLOGICAL INVASIONS; EXTRINSIC FACTORS; DIVERSITY; BIODIVERSITY; GRASSLAND; RESISTANCE; DISTURBANCE AB In the 1950s Charles Elton hypothesized that more diverse communities should be less susceptible to invasion by exotic species (biodiversity-invasibility hypothesis). The biodiversity-invasibility hypothesis postulates that species-rich communities are less vulnerable to invasion because vacant niches are less common and the intensity of interspecific competition is more severe. Field studies were conducted at two sites, a logged site and an unlogged site in Santa Rosa County, Florida, U.S.A, to test Elton's hypothesis using cogongrass (Imperata cylindrica), a non-indigenous grass invading large areas of the Southeastern United States. The logged site was under 17-year-old loblolly pine prior to clear cutting. The unlogged site, a longleaf pine forest, was at the Blackwater River State Forest. Both the logged site and unlogged site showed no significant relationship between the rate of cogongrass spread and native plant species richness, functional richness, and cover of the invaded community. Increased species or functional richness may increase the use of resources; however, the extensive rhizome/root network possessed by cogongrass and its ability to thrive under shade may allow for its persistence in a diverse community. The results from both the logged and unlogged sites do not support the general hypothesis of Elton that invasion resistance and compositional stability increase with diversity. Biodiversity does not appear to be an important factor for cogongrass invasion in the southern United States. Extrinsic factors in this study prevent the ability to draw a defined causal relationship between native plant diversity and invasibility. Underlying reasons for why no relationship was observed may be simply due to the tremendous competitive ability of cogongrass or the narrow range of species richness, functional richness and cover observed in our study.

Atria frequency, cyclic AMP (cAMP) accumulation, nitric oxide synthase (NOS) activity, and P-adrenoceptor-binding assay were then examined. Results showed that Se- mice have both a reduction in atria frequency as well as in cAMP content but higher NOS activity levels either at basal or after ISO stimulation. These differences were suppressed by feeding Se- mice with a Se- supplemented diet for 1 wk or by inhibition of inducible nitric oxide synthase (iNOS). Alterations observed after ISO stimulation in atria of Se- mice were not related to a P-adrenoceptor expression modification because specific radioligand-binding parameters in cardiac membranes from Se- mice and Se+ mice were similar. The reduced response on rate and cAMP in atria from Se- mice to direct adenylate cyclase (AC) stimulation by forskolin and the shifted upward levels present in 2-an-Lino-4-methylpyridine-treated Se- mice is in agreement with a negative crosstalk between NOS activity and AC activity in Se- mice.

Here, we present a comprehensive study of phylogenetic relationships within the Nymphaeales from a dataset containing 24 representatives of the order, including all currently recognized genera and all subgenera of the genus Nymphaea, plus 5 outgroup taxa. Nine different regions of the chloroplast genome - comprising spacers, group II introns, a group I intron, and a protein coding gene - were analysed. This resulted in a character matrix of 6597 positions and an additional 369 characters obtained from coded length mutations. Maximum parsimony and Bayesian analyses of the complete dataset yielded congruent, fully resolved and well-supported trees. Our data confirm the monophyly of the Cabombaceae but do not provide convincing support for the monophyly of Nymphaeaceae with respect to Nuphar. Moreover, the genus Nymphaea is inferred to be paraphyletic with respect to Ondinea, Victoria and Euryale. In fact, the Australian endemic Ondinea forms a highly supported clade with members of the Australian Nymphaea subgenus Anecphya. In addition, Victoria and Euryale are inferred to be closely related to a clade comprising all night-blooming water-lilies (Nymphaea subgenera Hydrocallis and Lotos). An experimental approach showed taxon sampling to be of influence on the nodes reconstructed in core Nymphaeaceae. The results underscore that more diverse genera, if not clearly known to be monophyletic, should be represented by all major lineages. (C) 2007 The Linnean Society of London.

TI Macrolichen diversity in subtropical forests of north-central Florida SO BRYOLOGIST LA English DT Article; Proceedings Paper CT 17th International Botanical Congress CY JUL 18-23, 2005 CL Vienna, AUSTRIA DE diversity; lichens; indicator species; species richness; subtropical forests; Florida; fire ID LICHEN; COMMUNITIES AB We sampled epiphytic and ground macrolichens in three subtropical forest types in north-central Florida (sand pine scrub, longleaf pine and hardwood bottoms). We detected 101 macrolichen taxa during community surveys in the three subtropical forest types. We used nonmeteric multidimensional scaling to determine factors associated with gradients in lichen community composition. In addition, we evaluated diversity of macrolichen species and species groups among the three vegetation types. Gradients in lichen community composition were closely associated with differences in vegetation structure (canopy cover, percent evergreen conifers) of the three forest vegetation types. Sand pine scrub forests supported the richest diversity and highest abundances of macrolichens, despite the young age of the stands. Sand pine scrub stands were young due to the frequency of stand-replacing fires. Alpha diversity averaged 26 macrolichen taxa per plot, ranging from 12 species in the youngest longleaf pine stand to 51 species in a mature sand pine scrub stand. Ground lichen cover ranged from 0-82% and, when present, formed a mat from 5-14 cm thick. Longleaf pine stands lacked ground lichen cover due to their dense grass understory and high fire frequency. These stands also had lower diversities and abundances of epiphytic macrolichens. The hardwood bottom vegetation type is often flooded with water and lacks both a consistent vascular plant and ground lichen cover. Hardwood bottoms experience fire infrequently and are intermediate in canopy lichen diversity. We used Indicator Species Analysis to determine if macrolichen species associated more closely with one or more of the three subtropical forest types studied. Lichen species indicative of sand pine scrub communities include Bulbothrix confoederata, Cladina evansii, C. subtenuis, Cladonia prostrata, C. ravenehi, Crocynia pyxinoides, Parmotrema sulfuratum and Usnea dimorpha. Dirinaria picta, Heterodermia albicans, Leptogium cyanescens, Ramalina americana and Ramalina willeyi were indicative of hardwood bottoms, and no lichen species were consistently indicative of longleaf pine communities.

Both Vespula vulgaris (L.) and Vespula germanica (F.), were captured in traps baited with isobutanol, the combination of acetic acid and isobutanol, and the combination of acetic acid and 2-methyl-2propanol. V. germanica did not respond to acetic acid or to heptyl butyrate. V. vulgaris also responded to acetic acid alone, and 2-methyl-2-propanol alone, but did not respond to heptyl butyrate. Both V. germanica and V. vulgaris responded more strongly to the combinations of acetic acid with isobutanol and acetic acid with 2-methyl-2-propanol, compared to any of these chemicals tested alone. Small numbers of European hornets, Vespa crabro L. were captured in traps baited with acetic acid with isobutanol, but not with any other lures. Small numbers of Dolichovespula media (Retzius) were captured in traps baited with acetic acid, and with the combination of acetic acid and isobutanol, but not with any other lures. The small numbers of Polistes nimpha (Christ) trapped were not large enough for any statistical analyses. These findings are the first European report of attracting and trapping vespid wasps with these chemicals. C1 USDA ARS, Yakima Agr Res Lab, Wapato, WA 98951 USA.

The present study was conducted to determine if short-term feed restriction in the prepuberal gilt would reduce BF gene transcript expression, pulsatile LH secretion and serum leptin concentrations. OVX prepuberal gilts 79 +/- 4 kg BW were control fed 3 kg (CF; n = 6) or feed restricted (RST; 33% of CF diet; n = 6) for 8 d to determine the effects of RST on leptin and LH secretion, metabolism, leptin, Ob-rb and transcription factor expression in BE Blood samples were collected on day 8 and BF on day 9. RST gilts lost BW (-2.5 vs. +8.2 kg; SE = 0.6 kg; P < 0.001) and BF (-3 vs. +2 mm; SE = 1mm; P < 0.02) compared with CF gilts. Postprandial serum T4 concentrations increased (P < 0.04) in CF, but not in RST pigs. Postprandial serum insulin and BHBA concentrations were similar between treatments. A treatment X time interaction was detected for plasma glucose (P < 0.02) and NEFA (P < 0.04) concentrations. Feed restriction failed to affect leptin or LH secretion except for LH pulse amplitude was greater (P < 0.01) in RST gilts. RST failed to affect BF leptin, Ob-rb, AFABP, C/EBP alpha, or PPAR gamma 2 expression. In conclusion, the ability of the prepuberal gilt to maintain energy level in the normal range suggests the prepuberal animal is resistant to moderate reduction in nutrition. Thus, leptin may not play a primary role in the regulation of LH secretion in the prepuberal gilt, but may serve as a metabolic signal reflecting the amount of stored energy, which may be necessary for activation of the reproductive axis during puberal development in the gilt.

Trees were 21 or 22ayears old at the time of the study. The function was used for demarcating corewood, transitional, and outerwood zones. Site and silvicultural effects were incorporated into the model. Heteroscedasticity and within-group correlation were accounted for by specifying the variance and serial-correlation structure, respectively. The estimated transition zone was located between rings 5 and 15, and the outerwood demarcation point varied from rings 12 to 15. No effects of treatments on the demarcation points were observed; however, site preparation and fertilization affected the lower asymptotes of the curves in all sites. A geographical trend for the demarcation point was observed, with the northern site requiring more time to reach a plateau in specific gravity compared with the southern sites. The diameter of the juvenile core was increased as a result of the treatments. However, the amount of corewood was not statistically affected, ranging from 55% in the north to 75% in the south, except at one site where fertilization decreased the percentage of corewood.

Franco) were monitored for 4 years following three wildfires. Logistic regression analyses were used to develop models predicting the probability of attack by Douglas-fir beetle (Dendroctonus pseudotsugae Hopkins, 1905) and the probability of Douglas-fir mortality within 4 years following fire. Percent crown volume scorched (crown scorch), cambium injury, diameter at breast height (DBH), and stand density index for Douglas-fir were most important for predicting Douglas-fir beetle attacks. A nonlinear relationship between crown scorch and cambium injury was observed, suggesting that beetles did not preferentially attack trees with both maximum crown scorch and cambium injury, but rather at some intermediate level. Beetles were attracted to trees with high levels of crown scorch, but not cambium injury, 1 and 2 years following fire. Crown scorch, cambium injury, DBH, and presence/absence of beetle attack were the most important variables for predicting postfire Douglas-fir mortality. As DBH increased, the predicted probability of mortality decreased for unattacked trees but increased for attacked trees. Field sampling suggested that ocular estimates of bark char may not be a reliable predictor of cambium injury. Our results emphasize the important role of Douglas-fir beetle in tree mortality patterns following fire, and the models offer improved prediction of Douglas-fir mortality for use in areas with or without Douglas-fir beetle populations.

Few fuel differences occurred among topographic positions for undisturbed plots, indicating that fuel accumulation is no greater on highly productive sites than on less productive sites. Litter was slightly higher on undisturbed upper slopes (4.2 t/ha) than on lower slopes (3.7 t/ha) but woody fuels showed no significant differences. Rhododendron (Rhododendron spp.) and mountain laurel (Kalmia latifolia L.) were less common than expected, occurring on 25% and 42% of sampled plots, respectively. Disturbance history and type played a greater role in determining fuel loads than did topographic position. Disturbances had occurred on 30% of sample plots within the past 10 years and were most common on exposed slopes. Litter was significantly lower in burned plots (3.5 t/ha vs. 4.0 t/ha in undisturbed plots). One-hour fuels (1.0 t/ha) were significantly higher on beetle-killed plots than on undisturbed plots (0.7 t/ha) while larger woody fuels tended to be greater in plots subjected to beetle attack, fire, and wind.

TI Applying class-based feature extraction approaches for supervised classification of hyperspectral imagery SO CANADIAN JOURNAL OF REMOTE SENSING LA English DT Article ID PRINCIPAL COMPONENT ANALYSIS; FEATURE REDUCTION; BAND SELECTION; ALGORITHMS AB Global band selection or feature extraction methods have been applied to hyperspectral image classification to overcome the "curse of dimension". We applied class-based feature extraction approaches and compressed the class data into different lower dimensional subspaces. Land cover classes in hyperspectral imagery could be roughly modelled as lowdimensional Gaussian clusters (i.e., "Gaussian pancakes") floating in sparse hyperspace. Each pixel was labelled accordingly based on conventional classifiers. We evaluated and compared the class-based version of principal components analysis (PCA), probabilistic principal components analysis (PPCA), and probabilistic factor analysis (PFA) algorithms to find the lower dimensional class subspaces in the training stage, projected each pixel, and then assigned the class label according to the maximum likelihood decision rule. Results from simulations and the classification of a compact airborne spectrographic imager 2 (CASI 2) hyperspectral dataset were presented. The proposed class-based PCA (CPCA) algorithm provided a reasonable trade-off between classification accuracy and computational efficiency for hyperspectral image classification. It proved more efficient and provided the highest classification kappa coefficient (0.946) among all band selection and feature extraction classifiers in our study. CPCA is recommended as a useful class-based feature extraction method for classification of hyperspectral imagery. C1 Missouri State Univ, Dept Geog Geol & Planning, Springfield, MO 65897 USA.

TI Short-term dynamics of second-growth mixed mesophytic forest strata in West Virginia SO CASTANEA LA English DT Article ID SOUTHERN APPALACHIAN FORESTS; PUNCTILOBULA MICHX MOORE; WHITE-TAILED DEER; NORTHERN RED OAK; SPATIAL HETEROGENEITY; OVERSTORY COMPOSITION; UNDERSTORY DIVERSITY; DECIDUOUS FORESTS; SEEDLING SURVIVAL; SOIL NUTRIENTS AB The short-term dynamics of mixed mesophytic forest strata in West Virginia were examined using similarity analysis and linear correlation of shared ordination space. The overstory tree, understory tree, shrub/vine, and herb strata were stable over a six year interval, whereas the tree seedling and sapling strata were unstable. All strata but the shrub/vine and tree seedling strata were correlated with soil pH, elevation, P, K, Fe, Mn, Co, and Mg, with the latter two variables being the weakest for the overstory tree, understory tree, and sapling strata. The herb stratum was also significantly correlated with the shrub/vine and tree seedling strata. The soil fertility gradient corresponded with a moisture gradient. More xeric plots tended to be less stable than more mesic plots for all strata. Successful forest management may depend on knowledge of the lower tree strata species composition, because such composition will likely vary prior to future disturbance events.

The hydrogen-bonded networks within these pure solvents correspond with experimentally determined water capacities for solvents in four main structural classes. These categories are: primary alcohols, secondary alcohols, tertiary alcohols, and alcohols with the branching point removed from the hydroxyl group. Each of these structural classes exhibits unique behavior in the correlation between the extended hydrogen-bond networks and observed capacities for water. (C) 2007 Elsevier Ltd. All rights reserved.

TI Heavy metal resistance and genotypic analysis of metal resistance genes in gram-positive and gram-negative bacteria present in Ni-rich serpentine soil and in the rhizosphere of Alyssum murale SO CHEMOSPHERE LA English DT Article DE heavy metals; Alyssum murale; serpentine soil; bacteria; PCR; metal resistance genes ID ALCALIGENES-EUTROPHUS CH34; NUCLEOTIDE-SEQUENCE; NICKEL; EXPRESSION; MICROORGANISMS; DETERMINANT; DIVERSITY; SYSTEM; OPERON; PMOL28 AB Forty-six bacterial cultures, including one culture collection strain, thirty from the rhizosphere of Alyssum murale and fifteen from Ni-rich soil, were tested for their ability to tolerate arsenate, cadmium, chromium, zinc, mercury, lead, cobalt, copper, and nickel in their growth medium. The resistance patterns, expressed as minimum inhibitory concentrations, for all cultures to the nine different metal ions were surveyed by using the agar dilution method. A large number of the cultures were resistant to Ni (100%), Pb (100%), Zn (100%), Cu (98%), and Co (93%). However, 82, 71, 58 and 47% were sensitive to As, Hg, Cd and Cr(VI), respectively. All cultures had multiple metal-resistant, with heptametal resistance as the major pattern (28.8%). Five of the cultures (about of 11.2% of the total), specifically Arthrobacter rhombi AY509239, Clavibacter xyli AY509235, Microbacterium arabinogalactanolyticum AY509226, Rhizobium mongolense AY509209 and Variovorax paradoxus AY512828 were tolerant to nine different metals. The polymerase chain reaction in combination with DNA sequence analysis was used to investigate the genetic mechanism responsible for the metal resistance in some of these gram-positive and gram-negative bacteria that were, highly resistant to Hg, Zn, Cr and Ni. The czc, chr, ncc and mer genes that are responsible for resistance to Zn, Cr, Ni and Hg, respectively, were shown to be present in these bacteria by using PCR. In the case of, M. arabinogalactanolyticum AY509226 these genes were shown to have high homology to the czcD, chrB, nccA, and mer genes of Ralstonia metallidurans CH34. Therefore, Hg, Zn, Cr and Ni resistance genes are widely distributed in both gram-positive and gram-negative isolates obtained from A. murale rhizosphere and Ni-rich soils. (C) 2006 Elsevier Ltd.

TI Emission, distribution and leaching of methyl isothiocyanate and chloropicrin under different surface containments SO CHEMOSPHERE LA English DT Article DE fumigant; pesticides; soil column; environmental fate; methyl bromide ID METAM-SODIUM; HEADSPACE ANALYSIS; FUMIGANT RESIDUES; SOIL FUMIGATION; DEGRADATION; BEHAVIOR; WATER AB The environmental fate of fumigants methyl isothiocyanate (MITC) and chloropicrin (CP) is of great concern for potential air and groundwater contamination while retaining sufficient concentrations for pest control efficacy. The emission, gas phase distribution, leaching, and persistence of MITC and CP were examined in repacked columns filled with sandy soils under three surface conditions: tarp without irrigation, tarp with limited irrigation, and 5-d irrigation without tarp, cover. For MITC, cumulative emission constituted 62%, 36%, and 0.3% of the amount applied under tarp without irrigation, tarp with limited irrigation, and 5-d irrigation without tarp surface conditions, respectively. The corresponding cumulative emission losses were 45%, 30%, and 5.4% for CP. During the first 24 h after injection, soil air concentrations of the two fumigants were much higher in the 15-25 cm depth range than other depths in the soil profile. Small amounts of leaching occurred for both fumigants, indicating potential for groundwater contamination should heavy rain fall or irrigation occurs immediately after soil fumigation. Very small amounts of residual MITC and CP (< 2%) were found in the soil 24 days after the experiment. The study clearly showed that atmospheric emission and degradation were the two primary pathways of MITC and CP dissipation during soil fumigation. Emission could be effectively reduced with 5-d irrigation if small leaching is acceptable or be prevented. (c) 2006 Elsevier Ltd. All rights reserved.

TI Monometal and competitive adsorption of heavy metals by sewage sludge-amended soil SO CHEMOSPHERE LA English DT Article DE cadmium; nickel; zinc; organic matter degradation ID DISSOLVED ORGANIC-MATTER; CADMIUM; COPPER; BIOSOLIDS; SORPTION; TIME; ZINC; AVAILABILITY; MOBILITY; CATIONS AB Sewage sludge-amended soils may alter their ability to adsorb heavy metals over time, due to the decomposition of sludge-borne organic matter. Thus, we studied Cd, Ni, and Zn adsorption by a sewage sludge-amended soil (Typic Xerofluvent) before and after one-year incubation in both monometal and competitive systems. In the monometal system, the order of decreasing sorption was Zn > Cd > Ni. Competition significantly reduced metal K-d, especially that of Cd which decreased by nearly 50%. Over the course of the incubation there was a 31% reduction of soil organic matter content. At the same time, in competitive systems Cd K-d significantly decreased, while Zn K-d significantly increased, and Ni K-d remained unaffected. This study shows that sewage sludge-amended soils may change in their ability to sorb heavy metals over time at high metal concentrations. The data suggest that Cd is likely to be of most environmental significance in such soils, since it exhibited decreased sorption under competitive conditions and as the organic matter content of the soil was reduced. The potential for long-term release of metals should be considered in the risk assessment associated with sewage sludge addition to soils, particularly in climates where degradation of organic matter is likely to be enhanced.

Methods: We studied the association between a functional APOA2 promoter polymorphism (-265T>C) and plasma lipids (fasting and postprandial), anthropometric variables, and food intake in 514 men and 564 women who participated in the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN) study. We obtained fasting and postprandial (after consuming a high-fat meal) measures. We measured lipoprotein particle concentrations by proton nuclear magnetic resonance spectroscopy and estimated dietary intake by use of a validated questionnaire. Results: We observed recessive effects for this polymorphism that were homogeneous by sex. Individuals homozygous for the -265C allele had statistically higher body mass index (BMI) than did carriers of the T allele. Consistently, after multivariate adjustment, the odds ratio for obesity in CC individuals compared with T allele carriers was 1.70 (95% CI 1.02-2.80, P = 0.039). Interestingly, total energy intake in CC individuals was statistically higher [mean (SE) 9371 (497) vs 8456 (413) kJ/d, P = 0.005] than in T allele carriers. Likewise, total fat and protein intakes (expressed in grams per day) were statistically higher in CC individuals (P = 0.002 and P = 0.005, respectively). After adjustment for energy, percentage of carbohydrate intake was statistically lower in CC individuals. These associations remained statistically significant even after adjustment for BMI. We found no associations with fasting lipids and only some associations with HDL subfraction distribution in the postprandial state. Conclusions: The -265T>C polymorphism is consistently associated with food consumption and obesity, suggesting a new role for APOA2 in regulating dietary intake.
