TI Production of butanol (a biofuel) from agricultural residues: Part II - Use of corn stover and switchgrass hydrolysates SO BIOMASS & BIOENERGY LA English DT Article DE Butanol; Clostridium beijerinckii P260; Agricultural residue hydrolysates; Corn (Zen mays) stover; Energy crop - switchgrass; (Panicum virgatum); Fermentation; Productivity; Yield; Overliming ID CLOSTRIDIUM-BEIJERINCKII; WHEAT-STRAW; FERMENTATION; SACCHARIFICATION; ACETONE; ACID AB Acetone butanol ethanol (ABE) was produced from hydrolysed corn stover and switchgrass using Clostridium beijerinckii P260. A control experiment using glucose resulted in the production of 21.06 g L(-1) total ABE. In this experiment an ABE yield and productivity of 0.41 and 0.31 g L(-1) h(-1) was achieved, respectively. Fermentation of untreated corn stover hydrolysate (CSH) exhibited no growth and no ABE production; however, upon dilution with water (two fold) and wheat straw hydrolysate (WSH, ratio 1:1), 16.00 and 18.04 g L(-1) ABE was produced, respectively. These experiments resulted in ABE productivity of 0.17-0.21 g L(-1) h(-1). Inhibitors present in CSH were removed by treating the hydrolysate with Ca(OH)(2) (overliming). The culture was able to produce 26.27 g L(-1) ABE after inhibitor removal. Untreated switchgrass hydrolysate (SGH) was poorly fermented and the culture did not produce more than 1.48 g L(-1) ABE which was improved to 14.61 g L(-1). It is suggested that biomass pretreatment methods that do not generate inhibitors be investigated. Alternately, cultures resistant to inhibitors and able to produce butanol at high concentrations may be another approach to improve the current process. Published by Elsevier Ltd.

Experiments were conducted to modify an existing method for the production of inoculum in temperate climates to make it more readily adoptable by farmers. Perlite, vermiculite. and peat based potting media were tested as diluents of yard clippings compost for the media in which the inoculum was produced using bahiagrass (Paspalum notatum Flugge) as host plant, All produced satisfactory concentrations of AM fungus propagules, though vermiculite proved to be better than potting media (89 vs. 25 propagules cm(-3), respectively). Two methods were tested for the growth of AM fungi indigenous to the farm: (1) adding field soil into the vermiculite and compost mixture and (2) pre-colonizing the bahiagrass seedlings in media inoculated with field soil prior to transplant into that mixture. Adding 100 cm(3) of field soil to the compost and vermiculite produced 465 compared to 137 propagules cm(-3) for the pre-colonization method. The greater flexibility these modifications give will make it easier for farmers to produce inoculum of AM fungi on-the-farm. Published by Elsevier Ltd.

TI On energy consumption for size-reduction and yields from subsequent enzymatic saccharification of pretreated lodgepole pine SO BIORESOURCE TECHNOLOGY LA English DT Article DE Size reduction; Disk-milling/refining; Forest/woody biomass; Enzymatic hydrolysis/sacchrification; SPORL ID PARTICLE-SIZE; CORN STOVER; FUEL ETHANOL; WOOD; POPLAR; BIOMASS; CHIPS; RATES; STEP AB This study investigated the effects of chemical pretreatment and disk-milling conditions on energy consumption for size-reduction and the efficiency of enzymatic cellulose saccharification of a softwood. Lodgepole pine wood chips produced from thinnings of a 100-year-old unmanaged forest were pretreated by hot-water, dilute-acid, and two SPORL processes (Sulfite Pretreatment to Overcome Recalcitrance of Lignocellulose) at acid charge on oven dry (od) wood of 0% and 2.21%. The pretreated wood chips were then milled using a laboratory disk mill under various solids-loadings and disk-plate gaps to produce substrates for enzymatic hydrolysis. We found that post-chemical-pretreatment size-reduction of forest biomass can decrease size-reduction energy consumption by 20-80% depending on the pretreatment applied under 20% solids-loading and a disk-plate gap of 0.76 mm in milling. SPORL with a sodium bisulfite charge of 8% and sulfuric acid charge of 2.21% on wood was the most effective in decreasing size-reduction energy consumption. Solids-loading had the most significant effect on disk-milling energy. When solids-loading was reduced from 30% to 3%, disk-milling energy could be decreased by more than a factor of 10 for wood chips pretreated by both SPORL and dilute-acid at an acid charge of 2.21%. The enzymatic hydrolysis glucose yields (EHGY) from the substrates produced by all pretreatments were independent of the solids-loading in milling. indicating that these energy savings in size-reduction can be realized without affecting EHGY. When wood chips were pretreated by SPORL with 2.21% acid charge, size-reduction energy consumption was decreased to less than 50 Wh/kg od wood at a practical solids-loading of approximately 10-20%, equivalent to that used in size-reduction of agriculture biomass, with excellent EHGY of about 370 g per kg od wood. Similar effects on size-reduction energy savings and excellent EHGY were also achieved when large disk-plate gaps (LIP to 1.52 mm studied) were applied in disk-milling of wood chips pretreated by SPORL with acid.

In order to evaluate their potential as materials for reinforcement, the nano-mechanical properties of crop-stalk cell walls, i.e. those of cotton (Gossypium herbaceu) stalk, soybean (Glycine max) stalk, cassava (Manihot esculent) stalk, rice (Oryza sativa L.) straw, and wheat (Triticum aestivum L.) straw, were investigated by means of nano-indentation and atomic force microscopy (AFM). The elastic modulus of wheat straw was found to be 20.8 GPa, which was higher than that of the other four crops. The highest hardness was observed in cotton stalk at 0.85 GPa. The elastic moduli of the crop stalks were lower than those of most of the hardwood species, but higher than that of some softwoods and of lyocell fiber. The mean value of the hardness of the five crop stalks' cell walls was higher than those of wood or lyocell fiber. (C) 2009 Elsevier Ltd. All rights reserved.

TI Lime pretreatment of switchgrass at mild temperatures for ethanol production SO BIORESOURCE TECHNOLOGY LA English DT Article DE Enzymatic hydrolysis; Ethanol; Lignocellulose; Lime pretreatment; Switchgrass ID METAL-CATIONS; LIGNIN; PRECIPITATION; RESIDUES AB To improve the enzymatic digestibility of switchgrass at mild temperatures. lime pretreatment of switchgrass was explored at 50 and 21 degrees C, and compared with that at 121 degrees C. The effects of residence time, lime loading, and biomass washing on the Sugar production efficiency were investigated. Pretreatments were evaluated based on the yields of biomass-derived sugars in the subsequent enzymatic hydrolysis. Under the best pretreatment conditions (50 degrees C, 24 h, 0.10 g Ca(OH)(2)/g raw biomass, and wash intensity of 100 ml water/g raw biomass), the yields of glucose, xylose, and total reducing sugars reached 239.6, 127,2, and 433.4 mg/g raw biomass, which were respectively 3.15, 5.78, and 3.61 times those of untreated biomass. The study on calcium-lignin bonding showed that calcium ions crosslinked lignin molecules under alkaline conditions, which substantially decreased lignin solubilization during pretreatment, but the resulting high lignin contents of the pretreated biomass did not compromise the improvement of enzymatic digestibility.

Both continents face challenges and opportunities for managing human-wildlife conflict at the junction of livestock production and wildlife conservation. Predation of livestock and disease transmission between wildlife and livestock is an ongoing and escalating worldwide issue. In order to manage this conflict, producers need effective tools, and they have used livestock protection dogs (LPDs) for reducing predation for well over 2000 years. We review the history of the use of LPDs, including the loss of information on their use and the paucity of scientific research on their effectiveness. We discuss the potential for LPDs to be integral components in modern-day livestock husbandry and outline future directions to pursue.

The potentiostatic performance of aerated S. oneidensis was considerably enhanced to a maximum current density of 0.45 A/m(2) or 80.3 A/m(3) (mean: 0.34 A/m(2), 57.2 A/m(3)) compared to anaerobically grown cultures. Biocatalyzed hydrogen production rates with aerated S. oneidensis were studied within the applied potential range of 0.3-0.9 V and were highest at 0.9 V with 0.3 m(3) H(2)/m(3) day, which has been reported for mixed cultures, but is similar to 10 times higher than reported for an anaerobic culture of S. oneidensis. Aerated MFC experiments produced a maximum power density of 3.56 W/m(3) at a 200-Omega external resistor. The main reasons for enhanced electrochemical performance are higher levels of active biomass and more efficient substrate utilization under aerobic conditions. Coulombic efficiencies, however, were greatly reduced due to losses of reducing equivalents to aerobic respiration in the anode chamber. The next challenge will be to optimize the aeration rate of the bacterial culture to balance between maximization of bacterial activation and minimization of aerobic respiration in the culture.

Using minimal medium with iron as the limiting nutrient, four different types of responses were obtained in a customized continuous culture system: (1) stable steady state, (2) damped oscillation, (3) normal washout due to high dilution rates exceeding the maximum growth rate, and (4) washout at low dilution rates due to negative growth rates. The type of response was determined by a combination of initial cell mass and dilution rate. Stable steady states were obtained with dilution rates ranging from 0.059 to 0.086 h(-1) with an initial cell mass of less than 0.6 OD(600). Damped oscillations and negative growth rates are unusual observations for bacterial systems. We have observed these responses at values of initial cell mass of 0.9 OD(600) or higher, or at low dilution rates (<0.05 h(-1)) irrespectively of initial cell mass. This response suggests complex dynamics including the possibility of multiple steady states. Iron, which was reported earlier as a growth limiting nutrient in a widely used minimal medium, enhances both growth and virulence factor induction in iron-supplemented cultures compared to unsupplemented controls. Intracellular iron concentration is correlated to the early induction (6 h) of virulence factors in both batch and chemostat cultures. A reduction in aconitase activity (a TCA cycle enzyme) and ATP levels in iron-limited chemostat cultures was observed compared to iron-supplemented chemostat cultures, indicating that iron affects central metabolic pathways. We conclude that DC3000 cultures are particularly dependent on the environment and iron is likely a key nutrient in determining physiology.

Carriere-Tsuga heterophylla (Raf.) Sarg.) stands were studied in seven replicate areas over seven growing seasons postthinning. Vegetative cover was analyzed at the class level, but species-specific effects were examined in relation to their value as food for Sitka black-tailed deer (Odocoileus hemionus sitkensis Cowan). When compared with unthinned controls, thinned stands (3.6-6.3 m spacing) had significantly greater understory cover. However, all thinned spacings led to similar understory cover. Conifer cover recovered to about two-thirds of its prethinning level within seven growing seasons posttreatment. Understory nonconiferous cover increased during the first 2-4 years postthinning but began to decline with increasing conifer cover during the next 3 years, nearly reaching pretreatment levels by year 7. In unthinned understories, vegetative cover had declined and was significantly lower than that beneath thinned stands. Summer food resource values for deer were increased by thinning. Winter food resource values were increased by thinning for snow-free conditions but were unaffected for conditions when herb-layer forbs were buried by snow.

Their efficiency in small-area estimation problems can be poor. In this study, we propose a modified balanced repeated replication estimator of variance (BRR) of a kNN total that performs well in small-area estimation problems and under both simple random and cluster sampling. The BRR estimate of variance is the sum of variances and covariances of unit-level kNN estimates in the area of interest. In Monte Carlo simulations of simple random and cluster sampling from seven artificial populations with real and simulated forest inventory data, the agreement between averages of BRR estimates of variance and Monte Carlo sampling variances was good both for population and for small-area totals. The modified BRR estimator is currently limited to sample sizes no larger than 1984. An accurate approximation to the proposed BRR estimator allows significant savings in computing time.

TI Thinning and site quality influence aboveground tree carbon stocks in yellow-poplar forests of the southern Appalachians SO CANADIAN JOURNAL OF FOREST RESEARCH-REVUE CANADIENNE DE RECHERCHE FORESTIERE LA English DT Article ID STAND VOLUME GROWTH; DOUGLAS-FIR; PONDEROSA PINE; HEMLOCK FORESTS; UNITED-STATES; STORAGE; STORES; CHRONOSEQUENCE; CONSEQUENCES; SIMULATION AB Little information exists regarding the effects of intermediate stand management activities (e.g., thinning) on C storage. This lack of information has created uncertainty regarding trade-offs between the benefits observed following thinning and C storage. Using long-term growth data, this study examines the effect of thinning on C storage while controlling for the effects of site quality in yellow-poplar (Liriodendron tulipifera L.) forests throughout the southern Appalachian Mountains. In 1960, one hundred and eighteen 0.1 ha plots were established in yellow-poplar forests throughout the southern Appalachians and subsequently thinned to a randomly assigned residual basal area (RBA) (square metres per hectare). Carbon storage increased through time across all levels of RBA. RBA had a long-term effect on C storage with greater C storage occurring at greater RBA. On average-quality sites, thinning to 30 m(2).ha(-1) stored 84% more C than thinning to 10 m(2).ha(-1). At no time did plots with progressively lower RBA store more C than plots with progressively higher RBA. The results from this study provide information about the effects of intermediate silvicultural disturbance on C dynamics of the aboveground live tree pool in a complex landscape and may be used to inform decisions regarding trade-offs between active management and C storage.

High soil water content greatly increases conductivity of frost. We develop a model based on the sum of z-scores of soil frost (December-February) and drought in summer (May-September) that accurately predicts timing and severity of dieback on sugar maple (Acer saccharum Marsh.), Betula spp., Fraxinus spp., and red spruce (Picea rubens Sarg.) in Maine, USA, during 1920-1995. Discrepancies between predicted and actual dieback relate largely to tree population dynamics. Extraordinary levels of dieback on Betula during 1935-1950 occurred under low stress but in mature populations; under high climate stress during 1951-1975, younger surviving Betula proved resistant and showed little dieback. Severe dieback in Acer stands during 1975-1995 may relate to extensive partial cutting, leaving stands open to frost and high water tables. Widespread use of forwarder feller/buncher and wheeled skidders after 1960 commonly left hummocky, irregular surfaces subject to pooling and accelerated frost penetration. Silvicultural applications include modifying harvesting practices to minimize frost complications and use of the model to track and map climatic risk to avoid conditions and locales subject to dieback.

We examined whether LiDAR data could be used to directly assess the successional stage of forests by determining the degree to which the LiDAR data would show the same relative ranking of structural development among sites as would traditional field measurements. We sampled 94 primary and secondary sites (19-93, 223-350, and 600 years old) from three conifer forest zones in western Washington state, USA, in the field and with small-footprint, discrete return LiDAR. Seven sets of LiDAR metrics were tested to measure canopy structure. Ordinations using the of LiDAR 95th percentile height, rumple, and canopy density metrics had the strongest correlations with ordinations using two sets of field metrics (Procrustes R = 0.72 and 0.78) and a combined set of LiDAR and field metrics ( Procrustes R = 0.95). These results suggest that LiDAR can accurately characterize forest successional stage where field measurements are not available. This has important implications for enabling basic and applied studies of forest structure at stand to landscape scales.

A key assumption in this process is that differences in canopy structure based on forest age and elevation are consistent with predictions from models of stand development. Three LiDAR metrics (95th percentile height, rumple, and canopy density) were computed for 59 secondary and 35 primary forest plots in the Pacific Northwest, USA. Hierarchical clustering identified two precanopy closure classes, two low-complexity postcanopy closure classes, and four high-complexity postcanopy closure classes. Forest development models suggest that secondary plots should be characterized by low-complexity classes and primary plots characterized by high-complexity classes. While the most and least complex classes largely confirmed this relationship, intermediate-complexity classes were unexpectedly composed of both secondary and primary forest types. Complexity classes were not associated with elevation, except that primary Tsuga mertensiana (Bong.) Carriere (mountain hemlock) plots were complex. These results suggest that canopy structure does not develop in a linear fashion and emphasize the importance of measuring structural conditions rather than relying on development models to estimate structural complexity across forested landscapes.

Sixteen and 8 open reading frames were mapped to these loci in E. coli O2:H4 U 9-41 and E. coli O28ac:H25 96-3286, respectively. The wzx (O-antigen flippase) and wzy (O-antigen polymerase) genes in the E. coli O2 and O28ac O-antigen gene clusters were selected as targets for PCR assays for their identification. PCR assays targeting the wzx and wzy genes were specific for these serogroups, with one exception. Escherichia coli serogroup 042 strains gave positive results with wzx and wzy PCR assays targeting E. coli O28ac, and antiserum raised against 042 cross-reacted with serogroup O28ac strains. The O-antigen gene cluster of a strain of E. coli serogroup 042 was sequenced, and there were only 3 nt differences between the O-antigen gene clusters of the O28ac and 042 strains. Multiplex PCR assays targeting the O2 wzx gene, the stx(1), stx(2), hly, eae, and saa genes, and the O28ac wzx, ial, ipaC, and ipaH genes were developed for detecting Shiga toxin-producing E. coli O2 strains and enteroinvasive E. coli O28ac strains, respectively. The O2 and O28ac wzx and wry genes can be used as diagnostic markers in PCR assays for rapid identification of these serogroups as an alternative to serotyping, and the multiplex PCR assays targeting serogroup-specific genes in combination with virulence genes can be used to identify and to detect pathogenic serogroup O2 and O28ac strains.

White-tailed deer (Odocoileus virginianus) congregate in matriarchal groups; kin-related close social spacing may be a factor in the spread of infectious diseases. Spread of chronic wasting disease (CWD), a prion disorder of deer and their cervid relatives, is presumed to be associated with direct contact between individuals and by exposure to shared food and water sources contaminated with prions shed by infected deer. Key aspects of disease ecology are yet unknown. DNA tools for pedigree reconstruction were developed to fill knowledge gaps in disease dynamics in prion-infected wild animals. Kinship indices using data from microsatellite loci and sequence haplotypes of mitochondrial DNA were employed to assemble genealogies. Molecular genealogy tools will be useful for landscape-level population genetic research and monitoring, in addition to epidemiologic studies examining transmission of CWD in captive and free-ranging cervids.

EDTA resulted in more solubilization of Pb than elemental sulfur in both soils. Application of EDTA and elemental sulfur increased shoot dry matter in the loamy sand soil, whereas in the sandy clay loam soil EDTA treated plants produced lower shoot dry matter compared to that observed with elemental sulfur. Application of EDTA 10 d prior to harvest increased the amount of Pb accumulated into wheat shoots with more Pb accumulated by plants from the loamy sand than from the sandy clay loam soil. However, evaluation of the relative extraction efficiency expressed as the percentage of solubilized Pb that is subsequently also effectively accumulated by the plant shoots reveals that the relatively low efficiency does not warrant the massive mobilization induced by the environmentally persistent EDTA chelator. More modest mobilization of Pb induced by elemental sulfur and the higher relative extraction of mobilized Pb therefore deserves further attention in future research. In particular, attention needs to be paid to determining soil types in which elemental sulfur can induce significant impact on soil pH and metal mobility after application of a practically realistic dosage.

TI IgA Antibody Response of Swine to Foot-and-Mouth Disease Virus Infection and Vaccination SO CLINICAL AND VACCINE IMMUNOLOGY LA English DT Article ID NEONATAL PIGLETS; IMMUNE-RESPONSES; REPERTOIRE DEVELOPMENT; MONOCLONAL-ANTIBODIES; CATTLE; LOCALIZATION; TRANSMISSION; RESISTANCE; PATTERNS; CARRIER AB Foot-and-mouth disease virus (FMDV) continues to be a significant economic problem worldwide. Control of the disease involves the use of killed-virus vaccines, a control measure developed decades ago. After natural infection, the primary site of replication of FMDV is the pharyngeal area, suggesting that a mucosal immune response is the most effective. Humoral immunity to killed-virus vaccination induces antibodies that can prevent the clinical disease but not local infection. Determining whether infection or vaccination stimulates IgA-mediated local immunity depends on the method of analysis. Different assays have been described to analyze the quality of antibody responses of cattle and swine to FMDV, including indirect double-antibody sandwich enzyme-linked immunosorbent assay (IDAS-ELISA) and antibody capture assay-ELISA (ACA-ELISA). We tested these assays on swine and show that vaccinated animals had FMDV-specific IgM and IgG but no IgA in either serum or saliva. After the infection, both assays detected FMDV-specific IgM, IgG, and IgA in serum. Notably, serum IgA was more readily detected using the ACA-ELISA, whereas IgA was not detected in saliva with this assay. FMDV-specific IgA antibodies were detected in saliva samples using the IDAS-ELISA. These data show that parenterally administered, killed-virus vaccine does not induce a mucosal antibody response to FMDV and illuminates limitations and appropriate applications of the two ELISAs used to measure FMDV-specific responses. Further, the presence of the IgA antivirus in serum correlates with the presence of such antibodies in saliva.

Methods: We estimated Db with SET and ADP in 131 healthy men and women with normal (N; 18.5-24.9 kg/m(2)), overweight (OW; 25-29.9 kg/m(2)), and obese (OB; 30-39.9 kg/m(2)) BMI. Results: Compared with ADP, SET overestimated (p < 0.05) Db in OW and OB females and in OB males (-0.0047, -0.0164 and -0.0119 g/cc, respectively), and underestimated (p < 0.05) Db in N females and males (0.0050 and 0.0068 g/cc, respectively) but did not differently estimate Db in OW males. The gender by BMI group interaction was not significant. SET underestimated (p < 0.05; 0.0058 g/cc) Db in the N and overestimated (p < 0.05: 0.0113 g/cc) Db in the OB BMI groups. The error in predicting Db did not change significantly over the range of Db within the N (r = 0.239, p = 0.06) and OB (r = 0.160, p = 0.934) BMI groups. Limits of agreement were -0.0165 to 0.0284 g/cc and -0.0365 to 0.0085 g/cc for the N and OB BMI groups, respectively. The error of estimating Db with SET was correlated with mean Db in the aggregate sample (r = 0.495, p < 0.0001) and the OW group (r = 0.394, p < 0.009). The regression-based limits of agreement were +/-0.0226 g/cc in the total group and +/-0.0168 g/cc in the OW group. Conclusions: Although SET offer practical advantages, the validity of SET to estimate Db among individuals with N and OB BMI is adversely affected.

Genetic estimators of both N (C) and N (e) are increasingly widely used because molecular markers are increasingly available, statistical methods are improving rapidly, and genetic estimators complement or improve upon traditional demographic estimators. We review the kinds and applications of estimators of both N (C) and N (e), and the often undervalued and misunderstood ratio of effective-to-census size (N (e) /N (C)). We focus on recently improved and well evaluated methods that are most likely to facilitate conservation. Finally, we outline areas of future research to improve N (e) and N (C) estimation in wild populations. C1 [Luikart, Gordon; Allendorf, Fred W.] Univ Montana, Div Biol Sci, Missoula, MT 59812 USA.

Here, we highlight some of the opportunities and challenges in using landscape genetic approaches in conservation biology. We first discuss challenges related to sampling design and introduce several recent methodological developments in landscape genetics (analyses based on pairwise relatedness, the application of Bayesian methods, inference from landscape resistance and a shift from population-based to individual-based analyses). We then show how simulations can foster the field of landscape genetics and, finally, elaborate on technical developments in sequencing techniques that will dramatically improve our ability to study genetic variation in wild species, opening up new and unprecedented avenues for genetic analysis in conservation biology.

Escapes into the wild began almost immediately after introduction. Today the combined range of the two species covers approximately 600 km(2) of southwestern Puerto Rico, where serious conflicts with agricultural interests have resulted. The Puerto Rico Department of Agriculture surveyed about 90% of commercial farmers in the range of the monkeys to begin quantifying damage by monkeys and the associated economic losses during the years 2002-2006. During that time, total economic losses by commercial farmers to monkeys increased from $1.13 million USD to over $1.46 million per year. Of these amounts, the economic losses due to farmers avoiding monkey damage by switching from fruit and vegetable crops to less rewarding land use (primarily hay or pastureland) increased from $490,000 to $1.33 million per year. The losses reported from the survey represent only a portion of economic losses to the invasive monkeys. Subsistence and other smaller farms and agriculture were not included in the survey. We also discuss many other economic issues surrounding the impacts of the invasive monkeys, but for which sufficient data are not available for economic analyses. These include concerns such as destruction of native (especially endangered) wildlife, threat of disease spread, and property damage, all of which would also have to be considered to fully evaluate invasive monkey economic impacts in Puerto Rico.

To establish the genetic bases for the biosynthesis of the mutagenic compound NG-391, we identified a 19,818 kb genomic region harboring the predicted hybrid polyketide synthase-nonribosomal peptide synthetase NGS1, plus five additional ORFs. NGS1 knockouts generated by Agrobacterium-mediated transformation failed to produce detectable levels of NG-391, indicating the involvement of this locus in its biosynthesis. NGS1 deletion mutants had no significant changes in virulence levels against larvae of Spodoptera exigua and in resistance to hydrogen peroxide-generated oxidative stress compared to the wild-type strain. All 6 ORFs were expressed in medium supporting production of NG-391, and NGS1 was expressed during the interaction with the S. exigua host. The use of an NGS1 promoter-GFP reporter fusion showed that during in vitro growth in still broth cultures, NGS1 expression is restricted to the early exponential phase and is affected by M. robertsii cell density.

We describe the complete sequence of the compact genome of Brachypodium distachyon (Brachypodium) the first pooid grass to be sequenced. We demonstrate the many favorable characteristics of Brachypodium as an experimental system and show how it can be used to navigate the large and complex genomes of closely related grasses. The functional genomics and other experimental resources that are being developed will provide a key resource for improving food and forage crops, in particular wheat, barley and forage grasses, and for establishing new grass crops for sustainable energy production.

Many associations from genome-wide association studies and candidate gene approaches have described a multitude of polymorphisms associating with lipid and obesity phenotypes but identified genetic variants account for only a small fraction of phenotypic variation. Recent findings That many genotype-phenotype associations involve variants under positive selection and that those variants respond to environmental cues together suggest prominent roles for both genetic adaptation and their interactions with the environment. Adaptive genetic variations interacting with environment modulate disease susceptibility but the level to which those variants contribute to dyslipidemia and obesity and how environmental factors, especially diet, alter the genetic association is not yet completely known. Summary It is evident that genetic variants under positive selection make important contributions to obesity and heart disease risk. Advances in resequencing the entire human genome will enable accurate identification of adaptive variants. Considering interactions between environmental factors and genotypes will empower both genome-wide association studies and characterization of the relationship between positive selection and the obese and dyslipidemic conditions.

TI Large in-stream wood studies: a call for common metrics SO EARTH SURFACE PROCESSES AND LANDFORMS LA English DT Editorial Material DE in-stream wood; field measurements; common metrics ID OREGON COAST RANGE; GRAVEL-BED RIVER; CHANNEL MORPHOLOGY; MOUNTAIN STREAMS; HEADWATER STREAMS; ORGANIC DEBRIS; BANKFULL DISCHARGE; WESTERN WASHINGTON; FLUVIAL PROCESSES; NATIVE FOREST AB During the past decade, research on large in-stream wood has expanded beyond North America's Pacific Northwest to diverse environments and has shifted toward increasingly holistic perspectives that incorporate processes of wood recruitment, retention, and loss at scales from channel segments to entire watersheds. Syntheses of this rapidly expanding literature can be facilitated by agreement on primary variables and methods of measurement. In this paper we address these issues by listing the variables that we consider fundamental to studies of in-stream wood, discussing the sources of variability in their measurement, and suggesting more consistency in future studies. We recommend 23 variables for all studies of in-stream wood, as well as another 12 variables that we suggest for studies with more specific objectives. Each of these variables relates either to the size and characteristics of in-stream wood, to the geomorphic features of the channel and valley, or to the ecological characteristics of the riparian zone adjacent to the study reach. The variables were derived from an overview of those cited in the literature and from our collective field experiences. Copyright (C) 2010 John Wiley & Sons, Ltd.

To predict future states of the boreal forest reliably, it is necessary to understand the complex interactions among forest regenerative processes (succession), natural disturbances (e.g., fire, wind, and insects), and anthropogenic disturbances (e.g., timber harvest). We used a landscape succession and disturbance model (LANDIS-II) to study the relative effects of climate change, timber harvesting, and insect outbreaks on forest composition, biomass (carbon), and landscape pattern in south-central Siberia. We found that most response variables were more strongly influenced by timber harvest and insect outbreaks than by the direct effects of climate change. Direct climate effects generally increased tree productivity and modified probability of establishment, but indirect effects on the fire regime generally counteracted the direct effects of climate on forest composition. Harvest and insects significantly changed forest composition, reduced living aboveground biomass, and increased forest fragmentation. We concluded that: (I) Global change is likely to significantly change forest composition of south-central Siberian landscapes, with some changes taking ecosystems outside the historic range of variability. (2) The direct effects of climate change in the study area are not as significant as the exploitation of virgin forest by timber harvest and the potential increased outbreaks of the Siberian silk moth. (3) Novel disturbance by timber harvest and insect outbreaks may greatly reduce the aboveground living biomass of Siberian forests and may significantly alter ecosystem dynamics and wildlife populations by increasing forest fragmentation.

A shoreline restoration project using ecological engineering approaches to mitigate coastal erosion was developed and implemented in 2003 at Loyola Beach, Baffin Bay, TX. The project incorporated riprap, fiber matting, geotextile, and vegetation as an alternative to conventional hard structures for erosion control. As part of the restoration expansion, a detailed evaluation of the previous project was completed at several levels, including the landscape, geotechnical design, environmental and ecological considerations, and social and economic factors. The findings indicated that the vegetation and its underlying geotechnical integrity have played an important role in erosion mitigation. Overall the project was successful in the protection of the shoreline and was shown to be more ecologically beneficial than other hard structures. Based on the preliminary success of the initial project, the restoration techniques were adapted for another beach extension to the west. The assessment did reveal some weaknesses in the original project design including the need for more substantial toe protection and periodic maintenance requirements. Based on these assessments, some additional new methods for the restoration extension were proposed and implemented. The broader applicability of this restoration approach outside the local region has been presented through several outreach activities and delivered to coastal planners and land owners throughout the Texas Coastal Bend and Northern Mexico.

TI Toward scrubbing the bay: Nutrient removal using small algal turf scrubbers on Chesapeake Bay tributaries SO ECOLOGICAL ENGINEERING LA English DT Article DE Algal turf scrubber; Algae; Nitrogen; Phosphorus; Estuary; Chesapeake Bay ID FRESH-WATER ALGAE; DAIRY MANURE EFFLUENT; LOADING RATES; ENERGY-PRODUCTION; MICROALGAE; BIODIESEL; RECOVERY; BIOMASS AB Restoration of the Chesapeake Bay poses significant challenges because of increasing population pressure, conversion of farmland to urban/suburban development, and the expense of infrastructure needed to achieve significant and sustained nutrient reductions from agricultural and urban sources. One radical approach for removing non-point source nutrients before they reach the bay is to deploy large-scale algal turf scrubbers along its tributaries. The objective of this study was to determine rates of nutrient removal and algal fatty acid production using small ATS units located along three Chesapeake Bay rivers. Smallscale ATS units (each containing 1 m(2) growing area) were operated for 5-10 months from April 2007 to April 2008 on three western shore tributaries of the Chesapeake Bay in Maryland: the Bush River, the Patapsco River and the Patuxent River. Total nitrogen (TN) and total phosphorus (TP) removal rates at the Patuxent site fluctuated considerably but averaged 250 mg TN, 45 mg TP m(-2) day(-1) from May to October 2007, then decreased to 16 mg TN, 3 mg TP m(-2) day(-1) from December 2007 to February 2008. Nutrient removal rates at the Bush river site also fluctuated but averaged only 85 mg TN, 10 mg TP m(-2) day(-1) from May to June 2007, before decreasing to <10 mg TN, <1 mg TP m(-2) day(-1) from July to September 2007. The Patapsco River unit began operation in August 2007, reached its maximum removal values of 150 mg TN, 18 mg TP m(-2) day(-1) from mid-October to late-November 2007, then decreased to values of 45 mg TN, 4 mg TP m(-2) day(-1) from November 15, 2007 to mid-April 2008. In the best case (Patuxent site from May to October 2007), daily removal rates of 250 mg N and 45 mg P m(-2) are equivalent to removal rates of 380 kg N and 70 kg P ha(-1) over a 150-day season in Maryland. Fatty acid (FA) content of the harvested material was consistently low (0.3-0.6% of dry weight) and varied little between sites. Mean algal FA production rates (23-54 mg FA m(-2) day(-1)) are equivalent to rates of 34-81 kg FA ha(-1) year(-1) based on a 150-day operational season in Maryland. Published by Elsevier B.V.

TI Consumer return chronology alters recovery trajectory of stream ecosystem structure and function following drought SO ECOLOGY LA English DT Article DE disturbance; functional group; grazer; Konza Prairie Biological Station, Kansas, USA; nonequilibrium; succession ID OXYGEN CHANGE TECHNIQUE; PRAIRIE STREAMS; COMMUNITY STRUCTURE; CHLOROPHYLL-A; DESERT STREAM; TOP-DOWN; SUCCESSION; DIVERSITY; DISTURBANCE; PERIPHYTON AB Consumers are increasingly being recognized as important drivers of ecological succession, yet it is still hard to predict the nature and direction of consumer effects in nonequilibrium environments. We used stream consumer exclosures and large outdoor mesocosms to study the impact of macroconsumers (i.e., fish and crayfish) on recovery of intermittent prairie streams after drying. In the stream, macroconsumers altered system recovery trajectory by decreasing algal and macroinvertebrate biomass, primary productivity, and benthic nutrient uptake rates. However, macroconsumer influence was transient, and differences between exclosures and controls disappeared after 35 days. Introducing and removing macroconsumers after 28 days resulted mainly in changes to macroinvertebrates. In mesocosms, a dominant consumer (the grazing minnow Phoxinus erythrogaster) reduced macroinvertebrate biomass but had little effect on algal assemblage structure and ecosystem rates during recovery. The weak effect of P. erythrogaster in mesocosms, in contrast to the strong consumer effect in the natural stream, suggests that both timing and diversity of returning consumers are important to their overall influence on stream recovery patterns. Although we found that consumers significantly altered ecosystem structure and function in a system experiencing rapid changes in abiotic and biotic factors following disturbance, consumer effects diminished over time and trajectories converged to similar states with respect to primary producers, in spite of differences in consumer colonization history. Thus, consumer impacts can be substantial in recovering ecosystems and are likely to be dependent on the disturbance regime and diversity of the consumer community.

Here, we investigated seed predation by deer mice (Peromyscus maniculatus) and its effects on recruitment of ponderosa pine (Pinus ponderosa) and Douglas-fir (Pseudotsuga menziesii) seedlings in unburned and recently burned fire-adapted montane forests in west-central Montana, USA. Deer mice were almost twice as abundant in burned than unburned stands. Deer mouse removal of seeds from petri dishes was two times higher in burned than in unburned stands, and seed removal levels were 8% higher for ponderosa pine than for the smaller Douglas-fir seeds. In seed-addition experiments, emergence of seedlings in deer mouse-exclusion cages was almost six times higher in burned compared to unburned forest. In both burned and unburned forest, emergence was lower for ponderosa pine than for Douglas-fir. Seedling survival to establishment did not differ between conifer species but was considerably higher in burned than in unburned forest. However, effects of seed predation on recruitment prevailed over fire effects: in cages allowing access by deer mice, emergence and establishment were extremely rare for both conifer species in both burned and unburned forest. This research suggests that consumer interactions can substantially influence recruitment even in fire-adapted forest ecosystems.

Since it was first identified in 2002 in southeast Michigan and Windsor, Ontario, dozens of isolated A. planipennis populations have been discovered throughout Michigan and Ontario, and in 12 other states and the province of Quebec. We assessed realized A. planipennis dispersal at two discrete outlier sites that originated 1 yr and 3 yr earlier from infested nursery trees. We systematically sampled ash trees within an 800 m radius of the origin of each infestation to locate galleries constructed by the progeny of dispersing A. planipennis adults. Our sampling identified eight trees at the 1 yr site infested with a mean +/- SE of 11.6 +/- 8.4 A. planipennis larvae and 12 trees at the 3 yr site with 25.8 +/- 11.1 larvae per meter squared. Dendroentomological analysis indicated that A. planipennis populations were predominantly undergoing a 2 yr (semivoltine) life cycle at both sites. Colonized trees were found out to 638 and 540 m from the epicenters at the 1 yr and 3 yr sites, respectively. Logistic regression was used to determine whether the likelihood of A. planipennis colonization was affected by wind direction, ash phloem abundance, distance from the epicenter, or land-use type (i.e., wooded, residential, agricultural, or urban). Results show that the probability of A. planipennis colonization was significantly affected by ash phloem abundance and decreased with distance from the epicenter. C1 [Siegert, N. W.; McCullough, D.

These species periodically reach outbreak densities, but it is unknown if they impact the population dynamics of later developing egg-overwintering grasshopper species. Two experiments were conducted in a northern mixed-grass prairie to examine the effects of herbivory by nymph-overwintering grasshoppers on survival of an egg-overwintering grasshopper, Ageneotettix deorum. When very high densities of nymph-overwintering grasshoppers reduced grass biomass by 80%, survival of A. deorum nymphs was significantly reduced. There was no effect of early season herbivory at a lower density of 16/m(2) on survival of A. deorum nymphs. The effects of early season herbivory appear consistent with exploitative competition. Although a strong reduction in peak grass biomass caused by early season herbivory negatively affected late season grass-feeding grasshopper densities, additional research is needed to examine the potential importance of early summer herbivory on population dynamics of later developing grasshoppers.

A CLIMEX model was developed for C. cactorum. Model validation was attempted at the global scale by comparing worldwide distribution against known occurrence records and at the field scale by comparing CLIMEX "growth indices" against field measurements of larval growth. Globally, CLIMEX predicted limited potential distribution in North America (from the Caribbean Islands to Florida, Texas, and Mexico), Africa (South Africa and parts of the eastern coast), southern India, parts of Southeast Asia, and the northeastern coast of Australia. Actual records indicate the moth has been found in the Caribbean (Antigua, Barbuda, Montserrat Saint Kitts and Nevis, Cayman Islands, and U.S. Virgin Islands), Cuba, Bahamas, Puerto Rico, southern Africa, Kenya, Mexico, and Australia. However, the model did not predict that distribution would extend from India to the west into Pakistan. In the United States, comparison of the predicted and actual distribution patterns suggests that the moth may be close to its predicted northern range along the Atlantic coast. Parts of Texas and most of Mexico may be vulnerable to geographic range expansion of C. cactorum. Larval growth rates in the field were estimated by measuring differences in head capsules and body lengths of larval cohorts at weekly intervals. Growth indices plotted against measures of larval growth rates compared poorly when CLIMEX was run using the default historical weather data. CLIMEX predicted a single period conducive to insect development, in contrast to the three generations observed in the field. Only time and more complete records will tell whether C. cactorum will extend its geographical distribution to regions predicted by the CLIMEX model. In terms of small scale temporal predictions, this study suggests that CLIMEX indices may agree with field-specific population dynamics, provided an adequate metric for insect growth rate is used and weather data are location and time specific.

Bacteria associated with the bark beetle Dendroctonus valens Le Conte from eight populations, ranging from Wisconsin to Oregon, were evaluated and compared. We used the culture-independent technique of denaturing gradient gel electrophoresis to visualize bacterial diversity, or individual operational taxonomic units (Os), from individual beetles. One-way analysis of similarities was used to test for differences of bacterial communities between sites. Analysis of community profiles showed that individual beetles on average contained 10 OTUs, with frequency of association from 2 to 100% of beetles. OTU sequences most closely matched beta- and gamma-proteobacteria, and one each matched Bacilli and Actinobacteria. Several OTUs were particularly abundant, most notably an Actinobacterium from 100% and two Proteobacteria from 60% of beetles sampled. Some OTUs were similar to previously described bacteria with known biochemical capabilities and ecological functions, suggesting that some bacterial associates of D. valens may contribute to its ability to exploit a resource low in nutrients and high in defensive compounds. There were significant differences of bacterial communities between sites. The strength of these differences was positively correlated with distance between sites, although additional unexplained factors also contribute to the variation.

The tsl strain Vienna 8 from the Ceratitis capitata Wied. (Diptera: Tephritidae), medfly, mass-rearing facility located in Juazeiro-BA, Brazil, was used. The results showed that sterile males either exposed or not to GRO exhibit similar dispersal behavior and postrelease survival. More than 60% of the sterile males, either treated or not treared wth GRO, were recovered at a 25-m distance from the releasing point, approximate to 20% at 50 m, and 5% in traps situated 100 m from the releasing point. Around 90% of the sterile males, exposed or not to GRO, were recovered 5 d after release of the sterile male individuals, whereas <1% were recovered after 11 d. Our results imply that ginger root oil can be used to treat sterile medfly males without interfering with their dispersal or survival in the field.

The clear caught significantly more moths of each sex than an orange delta trap when baited with ethyl (E,Z)-2,4-decadienoate (pear ester) and acetic acid (PE+AA) and performed similarly to oil-coated pane traps. The clear caught significantly more females than the orange delta trap with pear ester alone, pear ester plus (E,E)-8,10-dodecadien-1-ol (codlemone) (PE-PH), or a combination of PE-PH and acetic acid. Male moth capture was similar in both clear and colored delta traps with all codlemone lures tested. Seasonal moth catches of female moths were higher in clear than either white (second flight, 2008) or orange (first and second flights, 2009) traps baited with PE-PH. Total moth catch was significantly higher in clear than white traps in 2008 and did not differ between clear and orange traps in 2009. Clear traps baited with acetic acid but not with pear ester, PE-PH, or when unbaited caught significantly more nontarget moths than colored traps. These studies suggest that the use of clear traps with their higher captures of female codling moths could improve both monitoring programs and the development of lure and kill strategies.

Therefore, we conducted a 2-yr on-farm study to examine the attractiveness and possible cross-attraction of the reported pheromones for N. viridula and A. hilare and those previously discovered for Euschistus serous (Say) and Plautia stali Scott to N. viridula, A. hilare, and E. serous. The attractiveness of selected pentatomid pheromones to tachinid parasitoids of stink bugs was also examined. We showed for the first time under field conditions that N. viridula can be trapped with its reported pheromone, a 3:1 trans- to cis-(Z)-alpha-bisabolene epoxide blend. In fact, attraction of N. viridula increased with higher pheromone doses. Traps baited with a 5:95 trans- to cis-(Z)-alpha-bisabolene epoxide blend, the reported male-produced A. hilare attractant pheromone, failed to attract significantly more A. hilare than did unbaited control traps. Instead A. hilare was significantly cross-attracted to the P. stall pheromone [methyl (E,E,Z)-2,4,6-decatrienoate]. The E servus pheromone 1 methyl (E,Z) -2,4-decadienoate 1, either alone or in combination with P. stall pheromone, was more attractive to E. serous than to N. viridula, P. stali, or A. hilare pheromones. In general, tachinid parasitoids were found responsive to the male-specific volatiles of their known hosts, including the attractiveness of Trichopoda pennipes (F.) to sesquiterpenoid blends characteristic of A. hilare and N. viridula. A tachinid parasitoid of E. serous, Cylindromyia sp., seemed to be attracted to E. serous pheromone. In conclusion, our results indicate that stink bug traps baited with lures containing N. viridula pheromone blend, P. stall pheromone, and E. serum pheromone have the greatest potential for detecting populations of N. viridula, A. hilare, and E. serous, respectively, in diversified agricultural landscapes.

D. citri reproduces and develops only on the flushing shoots of its rutaceous host plants. Here we examined whether D. citri is attracted to host plant odors and a mixture of synthetic terpenes. Tests conducted in a vertically oriented Y-tube olfactometer showed that both males and females preferentially entered the Y-tube arm containing the odor from the young shoots of Murraya paniculata (L.) Jack and Citrus limon L. Burm. f. cultivar Eureka. Only males exhibited a preference for the odor of C. sinensis L., whereas the odor of C. x paradisi MacFadyen cultivar Rio Red was not attractive to both sexes. The volatiles emitted by young shoots of grapefruit cultivar Rio Red, Meyer lemon (Citrus x limon L. Burm.f.), and M. paniculata were analyzed by gas chromatograph-mass spectrometry. The samples were comprised of monoterpenes, monoterpene esters, and sesquiterpenes. The number of compounds present varied from 2 to 17, whereas the total amount of sample collected over 6 h ranged from 5.6 to 119.8 ng. The quantitatively dominant constituents were (E)-beta-ocimene, linalool, linalyl acetate, and beta-caryophyllene. The attractiveness of a mixture of synthetic terpenes, modeled on the volatiles collected from M. paniculata, was evaluated in screened cages in a no-choice test. At three observation intervals, significantly more individuals were trapped on white targets scented with the mixture than on unscented targets. These results indicate the feasibility of developing D. citri attractants patterned on actual host plant volatiles. C1 [Patti, J. M.] USDA ARS, Subtrop Agr Res Ctr, Weslaco, TX 78596 USA.

Solitary females in newly initiated galleries in ash logs produced (+)-exo-brevicomin, whereas male beetles paired with females produced (+)-endo-brevicomin, lesser quantities of (+)-exo-brevicomin, and a third compound that could not be identified. Beetles produced these compounds also after exposure to juvenile hormone HI, and they were the sole volatile chemicals isolated from beetles or aerations of infested logs that elicited electrophysiological responses from antennae of either sex. In the field, both sexes were strongly attracted to traps baited solely with either racemic or pure (+)-endo-brevicomin. Racemic exo-brevicomin was much less attractive to both sexes than racemic endo-brevicomin, and it did not increase attraction of endo-brevicomin when released in combination. Host odors (volatiles from mechanically damaged ash branches) failed to attract beetles or increase attractiveness of racemic exo-brevicomin. Our evidence suggests that male-produced (+)-endo-brevicomin is the major component of an aggregation pheromone for H. pruinosus, with (+)-exo-brevicomin and the unidentified male compound playing an indeterminate role in the chemical ecology of this species. Our data thus show an instance in which the major aggregation pheromone component of a bark beetle is produced by the secondarily arriving sex, a rare occurrence in bark beetles but one which has been reported previously for the Hylesini.

In one of a series of studies to evaluate whether S. schevyrewi is competitively displacing S. multistriatus in their North American zone of sympatry, we characterized long-range flight responses infested or uninfested to small cut logs of American, Chinese, and Siberian elm, Ulmus americana, U. parvifolia, and U pumila. Trials were conducted in Colorado and Wyoming to test the flight response of S. schevyrewi; in California to test the response of S. multistriatus; and in Nevada to test the responses of both species simultaneously. Studies with S. schevyrewi showed that males and females aggregated toward Ulmus spp. host volatiles but provided no evidence of a putative aggregation pheromone during the 0- to 48- or 48- to 96-h period of infestation. In contrast, S. multistriatus was attracted to U. pumila over unbaited controls, more to U. pumila infested with conspecific females than without, and more during the 48- to 96- versus 0- to 48-h period of infestation. This confirmed that male and female S. multistriatus aggregated toward host volatiles and that females produced an aggregation pheromone. In a cross-attraction study, S. schevyrewi displayed neither flight preference nor interruption to U. pumila infested with conspecifics, heterospecifics, or a mix of both species. Response of S. multistriatus was too low to draw conclusions. Although S. multistriatus aggregates moderately to host volatiles and strongly to female-derived pheromones emitted after a few days, S. multistriatus may have a relative disadvantage by selecting elm hosts more slowly than S. schevyrewi, which aggregates very strongly to host volatiles. The differential long-range host location strategy may be one factor in a chain of behavioral events that leads to advantageous host colonization and development by S. schevyrewi.

TI Effect of Methyl Salicylate-Based Lures on Beneficial and Pest Arthropods in Strawberry SO ENVIRONMENTAL ENTOMOLOGY LA English DT Article DE Carabidae; green lacewing; herbivore-induced plant volatiles; HIPV; lady beetles ID INDUCED PLANT VOLATILES; MITES NEOSEIULUS-CUCUMERIS; PREDATORY MITES; BEHAVIORAL-RESPONSES; FIELD-EVALUATION; INSECTS; ATTRACTANTS; HOST; EMISSIONS; WEEVIL AB Methyl salicylate (MeSA) is a common herbivore-induced plant volatile that, when applied to crops, has the potential to enhance natural enemy abundance and pest control. The impacts of MeSA in strawberry were unknown and examined in the spring and midsummer period. Strawberry plots contained no lures (control) or two 30-d MeSA lures (Predalure) in the center: one lure 0.61 m aboveground over a sticky trap, and one lure on a plant near the ground. Arthropod abundance was monitored at the point source, 5 m and 10 m away from lures over 31 d with white sticky traps, pitfall traps, and leaf inspection. Twenty-seven and nine comparisons were made among beneficial and pest arthropods, respectively. Overall positive responses were found among Chrysopidae in July-August 2008 and Onus tristicolor (White) in May-June 2009 to MeSA based on sticky traps. Chrysopidae showed attraction to the point source, but not at 5 m and 10 m. Ground-dwelling predators collected in pitfall traps such as Araneae, the carabid beetles, Pterostichus melanarius (Illiger), and Nebria brevicollis (Fabricius) did not respond. Increased abundance of six natural enemy groups appeared on various dates between 3 and 24 d after placement of lures in the field based on leaf inspection and sticky traps. Conversely, fewer Coccinellidae were captured on sticky traps on days 0-3, and fewer natural enemies were observed on leaves on day 28 in MeSA plots. MeSA did not increase nor decrease pest abundance. C1 USDA ARS, Hort Crops Res Lab, Corvallis, OR 97330 USA.

TI Boring in Response to Bark and Phloem Extracts From North American Trees Does Not Explain Host Acceptance Behavior of Orthotomicus erosus (Coleoptera: Scolytidae) SO ENVIRONMENTAL ENTOMOLOGY LA English DT Article DE bark beetle; boring incitant; host-range prediction; invasive species; Pinaceae ID IPS-PARACONFUSUS COLEOPTERA; FEEDING STIMULANTS; PHYTOPHAGOUS INSECTS; PINI COLEOPTERA; BEETLE SCOLYTUS; PONDEROSA PINE; BAITED TRAPS; MULTISTRIATUS; ANTIFEEDANTS; TYPOGRAPHUS AB When invasive herbivorous insects encounter novel plant species, they must determine whether the novel plants are hosts. The Mediterranean pine engraver, Orthotomicus erosus (Wollaston), an exotic bark beetle poised to expand its range in North America, accepts hosts after contacting the bark. To test the hypothesis that O. erosus accepts hosts on the basis of gustatory cues, we prepared bark and phloem extracts from logs of four North American tree species that we had used in previous host acceptance experiments. Water, methanol, and hexane extracts of red pine, tamarack, balsam fir, and paper birch were presented alone and in combination on a neutral filter paper substrate in a section of a plastic drinking straw. Boring behavior in response to the three-extract combinations differed from the pattern of acceptance previously observed among species when the beetles were in contact with the bark surface. Only the aqueous extracts of tamarack, Larix laricina, increased the initiation and the extent of boring by O. erosus on the filter paper substrate. We conclude that the effects of extracted chemicals do not match the behavior of the beetles observed when penetrating excised bark and phloem discs, indicating that host selection by O. erosus may not be predictable from bark and phloem chemistry alone. Instead, host acceptance may be determined by nongustatory stimuli or by a combination of stimuli including gustatory and nongustatory cues.

The weight of weevils reared on F1675 was more than twice as great as field-collected individuals. Recently, several ingredients included in the original F1675 diet were shown to have little or no effect on insect performance. We examined the effects of varying three ingredients of a simplified diet on the weight of adult D. abbreviatus. We used a geometric design combined with response surface models to evaluate the effects of the amount and proportion of diet ingredients to identify optimal diet recipes for normative weight gain defined in relation to field-collected D. abbreviatus from locations in Florida. Our results showed that it is possible to produce adults of normative weight or, for that matter, any mean weight within a wide range by varying the proportions of cottonseed meal, wheat germ and cellulose, a non-nutritive filler. Although wheat germ contributed to greater weight gain, survival of larvae to adult was lower on diets containing only wheat germ compared with diets containing only cottonseed meal as the principal nutritive components. The analyses of all the variables measured indicate that cottonseed meal is the only major nutritive component, in addition to standard vitamin and salt mixes, required to produce adult D. abbreviatus of normative weight.

We conducted a choice experiment study in three southern states in the United States: Arkansas, Florida, and Virginia. Reducing atmospheric CO(2), decreasing risk of wildfires and pest outbreaks, and enhancing biodiversity were presented to respondents as attributes of using biofuels. Results indicated that individuals had a positive extra willingness to pay (WTP) for both ethanol blends. The extra WTP was greater for higher blends that offered larger environment benefits. The WTPs for E10 were $0.56 gallon(-1), $0.58 gallon(-1), and $0.48 gallon(-1), and for E85 they were $0.82 gallon(-1), $1.17 gallon(-1), and $1.06 gallon(-1) in Arkansas, Florida, and Virginia, respectively. Although differences in WTP for E10 were statistically insignificant among the three states, significant differences were found in the WTP for E85 between AR and FL and between AR and VA. Preferences for the environmental attributes appeared to be heterogeneous, as respondents' were willing to pay a premium for E10 in all three states to facilitate the reduction of CO(2) and the improvement of biodiversity but were not willing to pay more for E85 in order to enhance biodiversity.

A whole genome oligonucleotide microarray was developed for Pf-5 and used to assess the global transcriptomic consequences of a gacA mutation in P. fluorescens Pf-5. In cultures at the transition from exponential to stationary growth phase, GacA significantly influenced transcript levels of 635 genes, representing more than 10% of the 6147 annotated genes in the Pf-5 genome. Transcripts of genes involved in the production of hydrogen cyanide, the antibiotic pyoluteorin and the extracellular protease AprA were at a low level in the gacA mutant, whereas those functioning in siderophore production and other aspects of iron homeostasis were significantly higher in the gacA mutant than in wild-type Pf-5. Notable effects of gacA inactivation were also observed in the transcription of genes encoding components of a type VI secretion system and cytochrome c oxidase sub-units. Two novel gene clusters expressed under the control of gacA were identified from transcriptome analysis, and we propose global-regulator-based genome mining as an approach to decipher the secondary metabolome of Pseudomonas spp. C1 [Shaffer, Brenda T.; Kidarsa, Teresa A.; Hartney, Sierra; Loper, Joyce E.] USDA ARS, Hort Crops Res Lab, Corvallis, OR USA.

TI Using photographic image analysis to assess ground cover: a case study of forest road cutbanks SO ENVIRONMENTAL MONITORING AND ASSESSMENT LA English DT Article DE Aspect; Cut slope; Best management practices; Road prism; Revegetation; Variable-sized sampling areas ID VEGETATION ESTABLISHMENT; SCIENTIFIC LITERATURE; EROSION; RUNOFF; SPAIN AB Road prisms, including cutbanks, road surfaces, and fillslopes, can be important contributors of sediment to streams in forested watersheds. Following road construction, cutbanks and fillslopes are often seeded, mulched, and sometimes fertilized to limit erosion and sedimentation. Assessing the success of vegetation establishment on cutbanks and fillslopes is a common task of forested land managers. This study developed and applied a photographic image analysis method to assess percent ground cover along an entire cutbank of a cut-and-fill haul road in the Monongahela National Forest in Tucker County, West Virginia. Variable-sized sections were employed to quantify the vegetative cover. Measurements obtained by this technique were similar to more commonly applied fixed-area plots, and it proved to be a useful tool for land managers who require a more repeatable quantification of ground cover than is possible through visual assessments. Cutbank slope and aspect also were analyzed to determine their potential impact on cutbank vegetation establishment. Slope was not a significant variable in explaining differences in vegetation cover; however, aspect did affect vegetation establishment. South-facing aspects had significantly lower percent vegetation cover than northeast, east, northwest, and north northwest aspects after the first year following seeding and throughout the entire study. Mean percent cover on the south-facing cutbanks was 32% over all time periods, compared to 60% to 73% for the other represented aspects. This result was expected since south-facing slopes generally are drier in the growing season and are subject to more freeze-thaw cycles in the winter. Timber felled onto the cutbank also decreased vegetative cover in the short term on north and north northwest aspects, but vegetation quickly became reestablished on these aspects with their favorable growing conditions.

We examined whether or not aspen plants grown under elevated CO2 and/or O-3 will acclimate after 11 years of exposure at the Aspen Face site in Rhinelander, WI, USA. We studied diurnal patterns of instantaneous photosynthetic measurements as well as A/C-i measurements monthly during the 2004-2008 growing seasons. Our results suggest that the responses of two aspen clones differing in O-3 sensitivity showed no evidence of photosynthetic and stomatal acclimation under either elevated CO2, O-3 or CO2 + O-3. Both clones 42E and 271 did not show photosynthetic nor stomatal acclimation under elevated CO2 and O-3 after a decade of exposure. We found that the degree of increase or decrease in the photosynthesis and stomatal conductance varied significantly from day to day and from one season to another. Published by Elsevier Ltd.

Local light climate at every leaf was characterized as fraction of above-canopy photosynthetic photon flux density (%PPFD). Elevated CO2 alone did not affect phi or P-max, and increased J(max) in the O-3-sensitive, but not in the O-3-tolerant clone. Elevated O-3 decreased leaf chlorophyll content and all photosynthetic parameters, particularly in the lower canopy, and the negative impact of O-3 increased through time. Significant interaction effect, whereby the negative impact of elevated O-3 was exaggerated by elevated CO2 was seen in Chl, N and J(max). and occurred in both O-3-tolerant and O-3-sensitive clones. The clonal differences in the level of CO2 x O-3 interaction suggest a relationship between photosynthetic acclimation and background O-3 concentration. (C) 2009 Elsevier Ltd. All rights reserved.

In this study, we investigated spring leaf flush and how long-term growth at elevated carbon dioxide concentration ([CO(2)]) and elevated ozone concentration ([O(3)]) altered leaf area index development in a closed Populus tremuloides (aspen) canopy. This work was done at the Aspen FACE experiment where aspen clones have been grown since 1997 in conditions simulating the [CO(2)] and [O(3)] predicted for similar to 2050. The responses of two clones were compared during the first month of spring leaf out when CO(2) fumigation had begun, but O(3) fumigation had not. Trees in elevated [CO(2)] plots showed a stimulation of leaf area index (36%), while trees in elevated [O(3)] plots had lower leaf area index (-20%). While individual leaf area was not significantly affected by elevated [CO(2)], the photosynthetic operating efficiency of aspen leaves was significantly improved (51%). There were no significant differences in the way that the two aspen clones responded to elevated [CO(2)]; however, the two clones responded differently to long-term growth at elevated [O(3)]. The O(3)-sensitive clone, 42E, had reduced individual leaf area when grown at elevated [O(3)] (-32%), while the tolerant clone, 216, had larger mature leaf area at elevated [O(3)] (46%). These results indicate a clear difference between the two clones in their long-term response to elevated [O(3)], which could affect competition between the clones, and result in altered genotypic composition in future atmospheric conditions.

The treatment effects on leaf surface characteristics were studied after nine years of tree exposure. CO2 and O-3 increased epidermal cell size and reduced epidermal cell density but leaf size was not altered. Stomatal density remained unaffected, but stomatal index increased under elevated CO2. Cuticular ridges and epicuticular wax crystallites were less evident under CO2 and CO2 + O-3. The increase in amorphous deposits, particularly under CO2 + O-3, was associated with the appearance of elongated plate crystallites in stomatal chambers. Increased proportions of alkyl esters resulted from increased esterification of fatty acids and alcohols under elevated CO2 + O-3. The combination of elevated CO2 and O-3 resulted in different responses than expected under exposure to CO2 or O-3 alone. (C) 2009 Elsevier Ltd. All rights reserved.

Efficient means to quantify such effects are beneficial. We hypothesized that changes in the balance of canopy interception, stem flow, and through-fall in the presence of elevated CO2 and O-3 could be discerned using image analysis of leafless branches. We compared annual stem flow to the results of a computerized analysis of all branches from the 2002, 2004, and 2006 annual growth whorls of 97 ten-year-old trees from the Aspen Free-Air CO2 and O-3 Enrichment (Aspen FACE) experiment in Rhinelander, WI. We found significant effects of elevated CO2 and O-3 on some branch metrics, and that the branch metrics were useful for predicting stem flow from birch, but not aspen. The results of this study should contribute to development of techniques for efficient characterization of effects on the forest hydrologic budget of increasing CO2 and tropospheric O-3.

While there are many important lessons to learn from the past, we believe that we cannot rely on past forest conditions to provide us with blueprints for future management. To respond to this uncertainty, managers will be challenged to integrate adaptation strategies into plans in response to changing climates. Adaptive strategies include resistance options, resilience options, response options, and realignment options. Our objectives are to present ideas that could be useful in developing plans under changing climates that could be applicable to forests with Mediterranean climates. We believe that managing for species persistence at the broad ecoregion scale is the most appropriate goal when considering the effects of changing climates. Such a goal relaxes expectations that current species ranges will remain constant, or that population abundances, distribution, species compositions and dominances should remain stable. Allowing fundamental ecosystem processes to operate within forested landscapes will be critical. Management and political institutions will have to acknowledge and embrace uncertainty in the future since we are moving into a time period with few analogs and inevitably, there will be surprises.

Farm tile drain and creek samples were collected from the drainage region: above and below a municipal wastewater treatment plant located upstream from the dairy; and downstream from animal housing, parlor, and fields receiving applied wastes. Fifty-four thousand tons of waste (from similar to 1000 milking head) were applied to similar to 809 ha from April to July. Maximum estradiol equivalents (E(2)Eqs) present in tile drain samples (<= 0.257 ng/L) were 2-fold maximum creek E(2)Eqs, but only 25% of the proposed no observable effect concentration for E(2) (1 ng/L). Relative manure slurry estrogen concentrations were estrone > 17 alpha-E(2) > 17 beta-E(2). Creek nutrient concentrations were similar above and below the dairy, with higher concentrations found in tile drain samples: tile ammonia ranged from <0.05 to 0.70 mg/L, nitrate/ite from 1.2 to 14 mg/L, and total phosphorus from 0.04 to 0.34 mg/L. No differences in estrogenic activity or nitrate/ite, ammonia, and phosphorus concentrations were detected in surface waters downstream of a large confinement dairy facility and measured nutrients were within regional norms.

TI Carbon Dioxide Addition to Microbial Fuel Cell Cathodes Maintains Sustainable Catholyte pH and Improves Anolyte pH, Alkalinity, and Conductivity SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID ION-EXCHANGE MEMBRANES; WASTE-WATER TREATMENT; ELECTRICITY-GENERATION; HYDROGEN-PRODUCTION; POWER-GENERATION; PERFORMANCE; CHAMBER; ELECTROLYSIS; SYSTEMS; CATION AB Bioelectrochemical system (BES) pH imbalances develop due to anodic proton-generating oxidation reactions and cathodic hydroxide-ion-generating reduction reactions. Until now, workers added unsustainable buffers to reduce the pH difference between the anode and cathode because the pH imbalance contributes to BES potential losses and, therefore, power losses. Here, we report that adding carbon dioxide (CO(2)) gas to the cathode, which creates a CO(2)/bicarbonate buffered catholyte system, can diminish microbial fuel cell (MFC) pH imbalances in contrast to the CO(2)/carbonate buffered catholyte system by Torres, Lee, and Rittmann [Environ. Sci Technol. 2008, 42,8773]. We operated an air-cathode and liquid-cathode MFC side-by-side. For the air-cathode MFC, CO(2) addition resulted in a stable catholyte film pH of 6.61 +/- 0.12 and a 152% increase in steady-state power density. By adding CO(2) to the liquid-cathode system, we sustained a steady catholyte pH (pH = 5.94 +/- 0.02) and a low pH imbalance (Delta pH = 0.65 +/- 0.18) over a 2-week period without external salt buffer addition. By migrating bicarbonate ions from the cathode to the anode (with an anion-exchange membrane), we increased the anolyte pH (Delta pH = 0.39 +/- 0.31), total alkalinity (494 +/- 6 to 582 +/- 6 as mg CaCO(3)/L), and conductivity (1.53 +/- 0.49 to 2.16 +/- 0.03 mS/cm) relative to the feed properties. We also verified with a phosphate-buffered MFC that our reaction rates were limited mainly by the reactor configuration rather than limitations due to the bicarbonate buffer.

Limited availability of meteorological records often constrains the applications of simulation models and related decision support tools. The Vegetation/Ecosystem Modeling and Analysis Project (VEMAP) provides daily weather variables on a 0.5 latitude-longitude grid across the conterminous USA. Daily weather data from the VEMAP (1961-1990) for the state of Georgia were compared with data from 52 individual ground stations of the National Weather Service Cooperative Observer Program (COOP). Additionally, simulated crop grain yields of soybean (Glycine max) were compared using the two data Sources. Averaged daily maximum and minimum temperatures (Tmax and Tmin, respectively), solar radiation (SRAD), and precipitation (PPT) differed by 0.2 degrees C, -0.2 degrees C, 1.7 MJ m(-2) d(-1), and 0 min, respectively. Mean absolute errors (MAEs) for Tmax, Tmin, SRAD, and PPT were 4.2 degrees C, 4.4 degrees C, 4.4 MJ m(-2) d(-1), and 6.1 min. respectively, and root mean squared errors (RMSEs) for Tmax, Tmin, SRAD, and PPT were 5.5 degrees C, 5.9 degrees C, 5.8 MJ m(-2) d(-1), and 13.6 mm, respectively. Temperature differences were lowest during summer months. Simulations of grain yield using the two data sources were strongly correlated (r = 0.68, p < 0.01). The MAE of grain yield was 552 kg ha(-1). The RMSE of grain yield was 714 kg ha(-1). Hybrid analyses indicated that the variation of simulated yield was mainly associated with the differences in rainfall. The results showed that the VEMAP daily weather data were able to be adequately applied to crop growth Simulation at spatial and temporal scales, especially for long-term climate change research. Overall, the VEMAP weather data appears to be a promising Source for crop growth modeling concerned with scale to 0.5 degrees coordinate grid. (C) 2009 Elsevier B.V. All rights reserved.

Typical symptoms of the disease are browning of vascular tissues, leaf wilt, defoliation, and tree decline. Unlike the symptoms of bacterial wilt disease caused by Ralstonia solanacearum, symptoms of MWD generally started from the bottom of the plants and moved upward. In inoculation experiments, four selected MWD strains caused mulberry shoot leaf wilt, discoloration, and defoliation. They also induced whole plant leaf wilt, defoliation and dark brown discoloration of vascular tissue. Based on Biolog metabolic profiles, fatty acid methyl ester analysis (FAME) and sequence analysis of the partial 16S rDNA and rpoB genes four MWD strains were identified as members of the genus Enterobacter. The 16S rDNA and rpoB gene sequences revealed a close relationship among two isolates, R2-2 and R6-2, and the E. asburiae type strain JCM6051. The isolates showed > 98% similarity to E. asburiae JCM6051 in their rpoB gene. These results indicated that isolates R2-2 and R6-2 belonged to E. asburiae. No similarity in 16S rDNA sequences above 97% was found between either of the remaining isolates, R11-2 or R18-2, and any recognized Enterobacter species, suggesting that the two isolates may represent novel Enterobacter species. rpoB gene similarity values between the isolates and Enterobacter spp. type strains were < 98%, providing further evidence that the two isolates may represent a novel species within the Enterobacter. The causal agent for MWD was previously reported to be E. cloacae, however, this study found that other Enterobacter spp. (E. asburiae and Enterobacter sp.) also cause MWD.

We now provide evidence that the aryl alcohol dehydrogenase NorA (AflE) encoded by the aflatoxin biosynthetic gene cluster in Aspergillus flavus affects the accumulation of aflatoxins in the final steps of aflatoxin biosynthesis. Mutants with inactive norA produced reduced quantities of aflatoxin B-1 (AFB(1)), but elevated quantities of a new metabolite, deoxyAFB(1). To explain this result, we suggest that, in the absence of NorA, the AFB(1) reduction product, aflatoxicol, is produced and is readily dehydrated to deoxyAFB(1) in the acidic medium, enabling us to observe this otherwise minor toxin produced in wild-type A. flavus.

In the survey, information on the above factors was collected for all persons in the village of 46 households (HHs) with a total population of 144 adults and 83 children. The survey revealed that persons who consume tamarind daily had significantly less (p<0.01) dental mottling, bamboo spine, and genu varum/genu valgum than occasional tamarind users. The incidence of skeletal and dental fluorosis was significantly higher among smokers than nonsmokers. About 95% of the HHs used Al utensils, which aggravated the fluorosis problem in the village. When the 3.6-ppm F water was stored undisturbed for 8 and 24 hr in an Al vessel, the F level decreased to 2.58 ppm and 2.36 ppm, respectively; boiling the water for 40 min in an Al utensil decreased the F level to 2.25 ppm. In conclusion, daily consumption of tamarind correlated with less dental and skeletal fluorosis, whereas smoking and the use of Al utensils for cooking appeared to enhance the effects of fluoride toxicity.

Although many studies have investigated the nutritional properties of DWG, little work has investigated the storability and shelf life for these feed products or how to measure these quantities. The objectives of this research were to measure the development of microorganisms and their respiration over time in freshly produced DWG and to determine if there was a quantitative relationship between these microbiological parameters and a more easily measured physical property, DWG color. The numbers of aerobic heterotrophic bacteria, molds and yeasts, and carbon dioxide generated by microbial respiration were measured at t = 0, 1, 2, 4, and 7 days as were Hunter color (L, a, b) values. All of the microbial parameters increased significantly over time (p < 0.05). Hunter L and a values appeared to change over time as well, but these differences became significant only at t = 7 days; at this time period, Hunter b changed significantly also. Hunter a and b values were negatively correlated with aerobic heterotroph numbers (r = -0.74 for Hunter a; r = -0.77 for Hunter b), yeast and mold counts (r = -0.78 for Hunter a; r = -0.81 for Hunter b), and CO(2) production (r = -0.89 for Hunter a; r = -0.87 for Hunter b). Hunter L values had moderate positive correlations with the microbial parameters (r values ranged from 0.42 to 0.57). Using Hunter a and b color parameters as predictor variables, multiple linear and nonlinear regressions produced R(2) values of 0.751, 0.665, and 0.816 for aerobic heterotrophs, molds and yeasts, and CO(2) generation, respectively. Additional research should quantify spoilage criteria, the relationship to palatability, and determine how best to use color changes as indicators of each. C1 [Rosentrater, K. A.; Lehman, R.

Ionizing radiation effectively inactivates planktonic Listeria, but no information is available on the relative efficacy of the process against biofilm-associated Listeria. The irradiation sensitivity of planktonic or biofilm cells was determined for L. monocytogenes ATCC 43256 and ATCC 49594 and a commonly used surrogate Listeria innocua ATCC 51742. Biofilms were formed on sterile glass slides incubated for 48 h at 22 degrees C, 28 degrees C, or 37 degrees C. The cultures were gamma irradiated and the irradiation D(10) value was calculated for each combination of isolate/culture/temperature. The effect of temperature of cultivation on the irradiation sensitivity of both planktonic cells and biofilm cells varied for each of the isolates. Depending on isolate and temperature, biofilm cells were equally sensitive or more sensitive (P < 0.05) to irradiation. D(10) values overall tended to increase with temperature of cultivation for L. monocytogenes 49594 and L. innocua 51742, but tended to decrease with increasing temperature for L. monocytogenes 43256. The D(10) values of the various culture/temperature combinations differed significantly among the isolates examined. Irradiation effectively eliminates both planktonic and biofilm-associated cells. The extent to which the biofilm habitat modifies the antimicrobial efficacy of irradiation is dependent on the specific isolate examined and the temperature at which it forms. This study is the first inquiry to show that biofilm Listeria cells are as sensitive or more sensitive to irradiation compared with planktonic cells and that this response is dependent on biofilm formation conditions.

HYB; GAS-CHROMATOGRAPHY; TRAILING BLACKBERRY; ENANTIOSELECTIVE ANALYSIS; FLAVOR COMPOUNDS; AROMA COMPOUNDS AB 'Black Diamond' is a recently developed thornless blackberry cultivar with large fruit size, high yield, and good processed fruit quality that has rapidly become an industry standard. The flavour of 'Black Diamond' fruit is not the same as 'Marion', which is regarded by the industry as having the ideal flavour. In order to understand the aroma differences, the volatile composition of 'Marion' and 'Black Diamond' was analysed using stir bar sorptive extraction-gas chromatography-mass spectrometry (SBSE-GC-MS) and solid-phase extraction (SPE)-microvial insert thermal desorption-GC-MS for two growing seasons. Although seasonal variations were present, the overall volatile profile in 'Marion' and 'Black Diamond' were very similar, but the concentrations of some aroma compounds varied greatly. Odour-activity value (OAV) indicated that furaneol, linalool, beta-ionone, and hexanal could be most important in 'Marion', while in 'Black Diamond', the most important compounds were linalool, beta-ionone, furaneol, and 2-heptanol. The major difference between the cultivars for aroma compounds was that 'Marion' had a 5 times higher OAV of furaneol than 'Black Diamond', while 'Black Diamond' had a 3 times higher OAV of linalool than 'Marion'. The chemical analysis results matched with the descriptive sensory evaluation that 'Marion' had more berry, fruity, strawberry aroma while 'Black Diamond' had more floral aroma.

Phenolic content of extracts increased with increasing temperature. In general, phenolic contents in microwave irradiated extracts were higher than those heated with a water bath. The highest phenolic content, 18.5 +/- 0.2 mg/g buckwheat, was observed in the extract that was microwave irradiated in 50% aqueous ethanol at 150 degrees C. The highest antioxidant activities, 5.61 +/- 0.04-5.73 +/- 0.00 mu mol Trolox equivalents/g buckwheat, were found in the 100% ethanol extracts obtained at 100 and 150 degrees C, independent of heat source. These results indicate that microwave irradiation can be used to obtain buckwheat extracts with higher phenolic content and similar antioxidant activity as extracts heated in a water bath.

AI-2 requires the luxS gene for its synthesis. The regulation of global gene expression in Salmonella Typhimurium by luxS/AI-2 is currently not known; therefore, the focus of this study was to elucidate the global gene expression patterns in Salmonella Typhimurium as regulated by luxS/AI-2. The genes controlled by luxS/AI-2 were identified using microarrays with RNA samples from wild-type (WT) Salmonella Typhimurium and its isogenic Delta luxS mutant, in two growth conditions (presence and absence of glucose) at mid-log and early stationary phases. The results indicate that luxS/AI-2 has very different effects in Salmonella Typhimurium depending on the stage of cell growth and the levels of glucose. Genes with p <= 0.05 were considered to be significantly expressed differentially between WT and DluxS mutant. In the mid-log phase of growth, AI-2 activity was higher (1500-fold) in the presence of glucose than in its absence (450-fold). There was differential gene expression of 13 genes between the WT and its isogenic DluxS mutant in the presence of glucose and 547 genes in its absence. In early stationary phase, AI-2 activity was higher (650-fold) in the presence of glucose than in its absence (1.5-fold). In the presence of glucose, 16 genes were differentially expressed, and in its absence, 60 genes were differentially expressed. Our microarray study indicates that both luxS and AI-2 could play a vital role in several cellular processes including metabolism, biofilm formation, transcription, translation, transport, and binding proteins, signal transduction, and regulatory functions in addition to previously identified functions. Phenotypic analysis of Delta luxS mutant confirmed the microarray results and revealed that luxS did not influence growth but played a role in the biofilm formation and motility.

TI Antimicrobial Drug Use and Antimicrobial Resistance in Enteric Bacteria Among Cattle from Alberta Feedlots SO FOODBORNE PATHOGENS AND DISEASE LA English DT Article ID FECAL ESCHERICHIA-COLI; BEEF-CATTLE; OXYTETRACYCLINE; PREVALENCE; CALVES; SUSCEPTIBILITY; CAMPYLOBACTER; FORMULATION; EFFICACY AB The purpose of this study was to determine whether antimicrobial resistance (AMR) in foodborne pathogens (Escherichia coli O157, Salmonella, and Campylobacter) and non-type-specific E. coli obtained from fecal samples of feedlot cattle was associated with antimicrobial drug (AMD) use. A secondary objective was to determine if AMR in non-type-specific E. coli could be used as a predictor of AMR in foodborne pathogens. Fecal samples were collected from pen floors in 21 Alberta feedlots during March through December 2004, and resistance prevalence was estimated by season (Spring, Fall) and cattle type (fewest days-on-feed and closest to slaughter). AMD exposures were obtained by calculating therapeutic animal daily doses for each drug before sampling from feedlot records. Generalized linear mixed models were used to investigate the relationship between each AMR and AMD use. Non-type-specific E. coli was commonly recovered from fecal samples (88.62%), and the highest prevalence of resistance was found toward tetracycline (53%), streptomycin (28%), and sulfadiazine (48%). Campylobacter jejuni was recovered from 55.3% of the fecal samples, and resistance was generally less for the drugs that were evaluated (doxycycline 38.1%, ciprofloxacin 2.6%, nalidixic acid 1.64%, erythromycin 1.2%). E. coli O157 and Salmonella were recovered much less frequently (7% and 1% prevalence, respectively). The prevalence of recovery for the bacteria studied varied between seasons and cattle types, as did patterns of AMR. Among non-type-specific E. coli, resistance to tetracycline, streptomycin, and sulfadiazine was found to be positively associated with in-feed exposure as well as injectable tetracycline, but these differences were relatively small and of questionable practical relevance. Among C. jejuni isolates, cattle type was significantly associated with doxycycline resistance. Results suggested that resistance in non-type-specific E. coli to chloramphenicol, trimethoprim/sulfamethoxazole, and tetracycline might be used as predictors of resistance to these drugs in E. coli O157 recovered from the same fecal samples.

The evaluation was based on precise top and base locations for >1,000 trees in 45 plots distributed across three forest types, a dense network of ground elevation recordings obtained with survey grade equipment, and LiDAR data from high return density acquisitions at leaf-on and leaf-off conditions. Overall, LiDAR error exceeded 10% of tree height for 60% of the trees and 43% of the plots at leaf-on and 55% of the trees and 38% of the plots at leaf-off. Total error was decomposed into contributions from errors in the estimates of tree top height, ground elevation model, and tree lean, and the relationships between those errors and stand- and site-level variables were explored. The magnitude of tree height error was much higher than those documented in other studies. These findings, coupled with observations that indicate suboptimal performance of standard algorithms for data preprocessing, suggest that obtaining accurate estimates of tree height via LiDAR in conditions similar to those in the US Pacific Northwest may require substantial investments in laser analysis techniques research and reevaluation of laser data acquisition specifications.

TI Influence of Crown Biomass Estimators and Distribution on Canopy Fuel Characteristics in Ponderosa Pine Stands of the Black Hills SO FOREST SCIENCE LA English DT Article DE canopy bulk density; canopy base height; crown allometry; fire hazard; crown biomass distribution ID REQUIRE LOCAL VALIDATION; LEAF-AREA; LOBLOLLY-PINE; VERTICAL-DISTRIBUTION; CONIFER STANDS; LODGEPOLE PINE; DOUGLAS-FIR; FOLIAGE; TREE; EQUATIONS AB Two determinants of crown fire hazard are canopy bulk density (CBD) and canopy base height (CBH). The Fire and Fuels Extension to the Forest Vegetation Simulator (FFE-FVS) is a model that predicts CBD and CBH. Currently, FFE-FVS accounts for neither geographic variation in tree allometries nor the nonuniform distribution of crown mass when one is estimating CBH and CBD. We develop allometric equations specific to ponderosa pine (Pinus ponderosa Dougl. ex Laws.) in the Black Hills to predict crown mass and use the Weibull distribution to model the vertical distribution of crown mass within individual trees. We present parameter prediction models that, in turn, predict the vertical distribution of crown mass based on stand- and tree-level attributes. With use of an FFE-FVS executable incorporating local crown mass equations and the parameter prediction models, new estimates of CBD and CBH were produced. Locally derived biomass equations predicted substantially greater estimates of foliage mass than currently predicted by FFE-FVS. The increase in CBD resulting from the local biomass and vertical distribution models averaged 78% over original estimates. Our results suggest that locally derived crown mass equations in addition to nonuniform estimates of crown mass distribution be used to calculate CBH and CBD as used in fire prediction models. FOR.

TI Effectiveness of Litter Removal to Prevent Cambial Kill-Caused Mortality in Northern Arizona Ponderosa Pine SO FOREST SCIENCE LA English DT Article DE raking; cambial kill; bark char; postfire mortality; prescribed fire ID CONIFER FOREST STRUCTURE; TREE MORTALITY; PRESCRIBED-FIRE; ECOLOGICAL RESTORATION; CRATER LAKE; GROWTH; OREGON AB Removal of deep litter and duff from the base of mature southwestern ponderosa pine (Pinus ponderosa Laws.) is commonly recommended to reduce mortality after prescribed burns, but experimental studies that quantify the effectiveness of such practices in reducing mortality are lacking. After a pilot study on each of four sites in northern Arizona, we monitored 15-16 sets of 8 matched trees on areas designated to be burned and adjacent not-burned sites and randomly assigned one of four litter and duff removal (to mineral soil) treatments: (1) rake to a distance of 23 cm from the bole, (2) leaf blow to a distance of 23 cm, (3) rake to a distance of 1 m, and (4) no litter or duff disturbance or removal. By 3 years postburn, no trees had died because of any of the treatments, but litter and duff removal prevented most cambial kill. However, 17% of the burned, no removal trees had some cambial kill. Litter and duff removal to 23 cm was as effective in preventing cambial kill and bole char as removal to 1 m, and there was no difference between removal by raking versus leaf blower removal. These results suggest that litter and duff removal is not needed to prevent ponderosa pine mortality after fall prescribed burns, but removal to 23 cm is adequate to prevent spots of cambial kill or moderate bark char.

A Poisson model of preventable Florida wildfires from 2002 to 2007 by fire management region was developed. Controlling for potential simultaneity biases, this model indicated that wildfire prevention education efforts have statistically significant and negative effects on the numbers of wildfires ignited by debris burning, campfire escapes, smoking, and children. Evaluating the expected reductions in wildfire damages given a change in wildfire prevention education efforts from current levels showed that marginal benefits exceed marginal costs statewide by an average of 35-fold. The benefits exceeded costs in the fire management regions by 10- to 99-fold, depending on assumptions about how wildfire prevention education spending is allocated to these regions. FOR.

In this article we examine attributes and defects known to affect the value of veneer logs and shed light on forest management considerations that affect veneer log production. Veneer attribute data were collected for black cherry (Prunus serotina Ehrh.), black walnut (Juglans nigra L.), northern red oak (Quercus rubra L.), sugar maple (Acer saccharum Marsh.), and white oak (Quercus alba L.). Social judgment theory was used to assess veneer attributes and defects. Color (hue and consistency) and rings (density and texture) are the drivers in veneer log selection, and the results are also indicated by a "Species by Color" interaction and a "Species by Rings" interaction. Other cues are important but do not appear to drive log selection. Hardwood forest management practices, in which partial cuttings are performed, can affect the potential product value of face veneer quality residual stems by changing the rate of diameter growth.

Furthermore, little is known about how genetic influences on tree phenotype change over time. We assessed clonal differences in 417 ramets, representing 18 clones, in a common garden of quaking aspen (Populus tremuloides Michx.) that have developed over 27 years. Genetic contributions to variation in physiology, growth, and vigor were determined over seasonal and multidecadal time scales. The 18 aspen clones exhibited wide-ranging phenotypic variation with two- to threefold differences in physiology and growth traits and more than sevenfold differences in canopy decline and mortality. For growth traits, strong genetic correlations (typically greater than 0.70) and heritability (estimates maintained in a range of 0.25 to 0.36), indicate that genotype had a moderate and consistent influence on growth over the three decades of the study. Physiological traits had much lower genetic correlations and heritability estimates, and they changed significantly within a single growing season. Climatic data suggest that dry conditions in the common garden as the summer progressed may have had a controlling influence on physiological trait responses. Characterizing genetically based phenotypic variation and how it contributes to clone vigor provides a critical link to understanding constraints to aspen viability in its western range. FOR.

Relative density, height and site quality were combined in a conceptually sound expression of the relationship between growth and growing stock for ponderosa pine-dominated stands of relatively simple structure. Predictions from this model were compared with productivity of more compositionally and structurally diverse stands. Our results are consistent with the common observation in forest production ecology that stand growth is not strongly influenced by either compositional or structural diversity.

TI Assessing forestland area based on canopy cover in a semi-arid region: a case study SO FORESTRY LA English DT Article ID UNITED-STATES; PREDICTION MODELS; DEFORESTATION; GRASSLANDS AB Forestland area estimates are the first principle of most ecological assessments across spatial scales. The definition of forest used by the United Nations Food and Agriculture Organization is based on a 10 per cent canopy cover threshold while the definition of forest used by the US Forest Service Forest Inventory and Analysis programme in western woodlands is based on a 5 per cent canopy cover threshold. Most of the eastern US forests have the ability to reach 10 per cent cover; however, in semi-arid areas such as western Texas, there is considerable area of forestland with less than 10 per cent canopy cover. The main objective of this research was to provide an estimate of forestland area in west Texas based on a 10 per cent canopy cover threshold. To accomplish this, we developed and compared three classification models that discriminate between inventory plots with less than 10 per cent cover and those with at least 10 per cent cover. We found that similar to 3.9 million ha (17 per cent) of forestland area (based on 5 per cent cover) did not meet the 10 per cent canopy cover threshold. C1 [Coulston, J. W.; Oswalt, S.

Morphological similarity, forage-base homogeneity and increasing animal density each enhance the likelihood of competitive interactions among sympatric populations. Competition is an interspecific relationship with mutually negative effects, and it is often confused with amensalism. Although competition or amensalism is commonly assumed, they have been very difficult to confirm in applied management settings, perhaps because field research has not typically examined relationships across temporal and spatial scales sufficient to linking short-term or small-scale interactions with longer-term reproductive performance. Perhaps by default, neutral coexistence has been concluded in many studies, and experimental research has suggested that facilitative relationships, in which resource overlap is actually beneficial, are possible as well. Forage-mediated relationships among ungulates can be strongly influenced by disturbance-induced landscape dynamics, through which forage composition (diversity), production, quality and pattern mosaics are modified. Unfortunately, different management entities are responsible for ungulate populations and landscapes, respectively, and these entities often approach their respective problems at differing temporal and spatial scales. These scales of management may or may not align with the scales at which interactions between herbivores and plants play out. The overarching challenge facing managers is to develop information systems through which multi-species management can be planned so as to demonstrably contribute to long-term ecosystem sustainability while also maintaining its socio-economic viability.

Using quantitative real-time RT-PCR, changes in ovarian mRNA expression of six TGF beta members and two inhibitors were investigated in rainbow trout across a wide range of fish ovarian stages (i.e., early perinucleous stage through acquisition of maturational competence). Transcript changes for insulin-like growth factor 1 and 2, and five enzymes associated with steroidogenesis, as well as plasma levels of three sex steroids were also measured to provide a framework of established intraovarian regulators in trout. Expression of bone morphogenetic protein 4 (bmp4), bone morphogenetic protein 7 (bmp7), and growth differentiation factor 9 (gdf9) peaked during pre-vitellogenic stages and steadily decreased through advancing stages implicating these genes in early ovarian development. A dramatic increase in inhibin beta(A) and decrease in follistatin expression occurred during early to mid-vitellogenic stages, which corresponded with increased 17 beta-estradiol plasma levels suggesting a vitellogenic role for ovarian activin A. Follicles that were competent to respond to the maturation-inducing hormone had decreased levels of inhibin beta(B) and increased expression of bambi (bmp and activin membrane-bound inhibitor) suggesting their roles in maturation processes. Furthermore, bmp4, bmp7 and gdf9 are primarily expressed in the oocyte whereas the inhibin subunits, follistatin, and bambi are primarily expressed in the somatic follicle cells. These results support TGF beta superfamily members and their inhibitors have wide-ranging and disparate roles in regulating ovarian development in fish. Published by Elsevier Inc.

Seven nuclear loci and 32 chloroplast loci were used in the analysis of 182 hop accessions including wild European (68), wild American (48), and cultivars (66). A total of 116 alleles were identified using 7 nuclear microsatellites showing different averages of polymorphism and distribution in the wild American and European accessions and cultivars. Two main groups were established as revealed by several statistical analyses; one including European wild accessions and cultivars and a second group consisting of American wild accessions. Three polymorphic chloroplast microsatellite loci were detected, six alleles were scored which defined a total of five haplotypes that were exclusive or presented different distribution between American and European wild accessions. A major influence of the wild European haplotypes was detected among hop cultivars. To the best of our knowledge, this is the first work reporting the use of chloroplast microsatellites in hops.

Nine ex situ and three in situ populations of the Dongxiang wild rice (DXWR) and four groups of modern cultivars were genotyped using 21 SSR markers for study of population structure, conservation efficiency and genetic relationship. We demonstrated that the ex situ conservation of the DXWR failed to maintain the genetic identity and reduced genetic diversity. Therefore, in situ conservation is absolutely necessary to maintain the genetic identity, diversity and heterozygosity. Also, in situ conservation is urgently needed because natural populations in DXWR have decreased from nine to three at present due to farming activity and urban expansion. In DXWR, the three surviving in situ populations had greater expected heterozygosity than any cultivated rice, and were genetically closer to japonica than either the male-sterile maintainer or restorer lines, or indica. Japonica has the lowest genetic diversity of cultivated rice. As a result, DXWR is a rich gene pool and is especially valuable for genetic improvement of japonica rice because these O. rufipogon accessions are most closely related to the japonica as compared to O. rufipogon collected anywhere else in the world.

However, the diversity in markers and populations used in individual mapping studies limits the ability to fully integrate the available data. By concentrating on marker orders rather than marker distances, published map data could be used to produce a comprehensive reference map (CRM) that includes a majority of known markers with optimally estimated order of those markers across the genome. In this study, a tetraploid cotton genome-wide CRM was constructed from 28 public cotton genetic maps. The initial CRM contained 7,424 markers and represented over 93% of the combined mapping information from the 28 individual maps.

SO GEOMORPHOLOGY LA English DT Article; Proceedings Paper CT 40th Binghamton Gromorphology Symposium CY OCT 02-04, 2009 CL Virginia Tech Blacksburg, Blacksburg, VA HO Virginia Tech Blacksburg DE Streambank stability; Riparian vegetation; Evapotranspiration; Hydraulic erosion; Sensitivity analysis ID CRITICAL SHEAR-STRESS; SOUTHWESTERN VIRGINIA; PLANT-ROOTS; SPATIAL VARIABILITY; COHESIVE STREAMBEDS; SUBAERIAL PROCESSES; CONCENTRATED FLOW; SOIL ERODIBILITY; DETACHMENT RATE; VEGETATION AB Riparian vegetation has a number of effects on the mechanisms by which streambanks fail, some positive and some negative. Previous research has shown that the effect of mechanical root-reinforcement on soil stability can be considerable, and can be successfully quantified and included in streambank stability models. Root networks contained within a soil-matrix, however, also have effects on the hydrologic and hydraulic processes acting on a streambank, and although these effects are often discussed they have generally been difficult to quantify. This paper summarizes the results of field data collection, laboratory testing and computer simulations carried out to better quantify the effects of riparian vegetation on hydrologic and hydraulic processes occurring along streambanks. First, the evapotranspiration potentials of different riparian species were isolated by setting up an experiment to grow young riparian trees and switch grass in separate soil columns, each instrumented with tensiometers at 30 cm and 70 cm depths, and compared against bare control columns. The hydrological reinforcement provided to the soil from increased apparent cohesion as a result of enhanced matric suction was estimated to range from 1.0 to 3.1 kPa in spring when bank stability was most critical and up to a maximum of 5.0 kPa in the summer. Second, a vertical jet-test device was used to measure rates and volumes of scour in soils permeated by switch grass roots. Results showed that the volume of soil scoured during a test declined non-linearly with increasing root volume, per unit volume of soil, and with increasing root length density (RLD) and increasing root biomass. Calculation of relative soil detachment rates (RSD) showed that with the highest rooting densities measured in the field jet-tests, eroded soil volume was 10% of that in the tests with no roots. Third, the effects of enhanced matric suction from evapotranspiration, and decreased soil erodibility because of the presence of plant roots were modeled using BSTEM 5.1 to quantify the effects on streambank factor of safety (F(s)), and to compare with the effects of mechanical root-reinforcement. The sensitivity analysis showed that the change in soil matric suction from evapotranspiration provided the greatest potential benefit to F(s) but only during the summer months. During the winter and spring months, root-reinforcement remained the most important contributor to F(s). The sensitivity analysis conducted here also showed that whilst roots are capable of reducing the volume of hydraulic scour, the resulting effect on streambank geometry did not increase F(s) as much as changes in soil matric suction and/or mechanical root-reinforcement.

Disturbance can play an important role in these dynamics, by initiating cycles of secondary succession and generating opportunities for communities of long-lived organisms to reorganize in alternative configurations. This study used landscape-scale variations in environmental conditions, stand structure, and disturbance from an extreme fire year in Alaska to examine how these factors affected successional trajectories in boreal forests dominated by black spruce. Because fire intervals in interior Alaska are typically too short to allow relay succession, the initial cohorts of seedlings that recruit after fire largely determine future canopy composition. Consequently, in a dynamically stable landscape, postfire tree seedling composition should resemble that of the prefire forest stands, with little net change in tree composition after fire. Seedling recruitment data from 90 burned stands indicated that postfire establishment of black spruce was strongly linked to environmental conditions and was highest at sites that were moist and had high densities of prefire spruce. Although deciduous broadleaf trees were absent from most prefire stands, deciduous trees recruited from seed at many sites and were most abundant at sites where the fires burned severely, consuming much of the surface organic layer. Comparison of pre- and postfire tree composition in the burned stands indicated that the expected trajectory of black spruce self-replacement was typical only at moist sites that burned with low fire severity. At severely burned sites, deciduous trees dominated the postfire tree seedling community, suggesting these sites will follow alternative, deciduous-dominated trajectories of succession. Increases in the severity of boreal fires with climate warming may catalyze shifts to an increasingly deciduous-dominated landscape, substantially altering landscape dynamics and ecosystem services in this part of the boreal forest.

TI Xylan-regulated delivery of human keratinocyte growth factor-2 to the inflamed colon by the human anaerobic commensal bacterium Bacteroides ovatus SO GUT LA English DT Article ID INFLAMMATORY-BOWEL-DISEASE; INTESTINAL EPITHELIAL-CELLS; ULCERATIVE-COLITIS; LACTOCOCCUS-LACTIS; MURINE COLITIS; INTERLEUKIN-10; MICE; MUCOSITIS; RECEPTOR; REPAIR AB Background Human growth factors are potential therapeutic agents for various inflammatory disorders affecting the gastrointestinal tract. However, they are unstable when administered orally and systemic administration requires high doses increasing the risk of unwanted side effects. Live microorganism-based delivery systems can overcome these problems although they suffer from the inability to control heterologous protein production and there are concerns regarding biosafety and environmental contamination. Methods To overcome these limitations we have developed a new live bacteria drug-delivery system using the human commensal gut bacterium Bacteroides ovatus engineered to secrete human growth factors in response to dietary xylan. The anaerobic nature of B ovatus provides an inherent biosafety feature. B ovatus strains expressing human keratinocyte growth factor-2, which plays a central role in intestinal epithelial homeostasis and repair (BO-KGF), were generated by homologous recombination and evaluated using the dextran sodium sulfate (DSS)-induced model of intestinal epithelial injury and colitis. Results In response to xylan BO-KGF produced biologically active KGF both in vitro and in vivo. In DSS treated mice administration of xylan and BO-KGF had a significant therapeutic effect in reducing weight loss, improving stool consistency, reducing rectal bleeding, accelerating healing of damaged epithelium, reducing inflammation and neutrophil infiltration, reducing expression of pro-inflammatory cytokines, and accelerating production of goblet cells. BO-KGF and xylan treatment also had a marked prophylactic effect limiting the development of inflammation and disruption of the epithelial barrier. Conclusion This novel, diet-regulated, live bacterial drug delivery system may be applicable to treating various bowel disorders.

Trees were grown with different rates of N from either urea formaldehyde (UF) or a controlled-release fertilizer (CRF) containing ammonium nitrate during the 2006 growing season; and growth, N and carbon (C) composition, and cold tolerance were evaluated in Oct. 2006, Dec. 2006, and Feb. 2007 by assessing the lowest survival temperature (LST) of stem and bud tissues on current season (2006) stems. Both fertilizer type and rate influenced the bud and stem LSTs. The influence of fertilizer rate was most evident on midwinter (December) stem LSTs and the influence of fertilizer type was observed in bud and stem LSTs during the deacclimation period in February. Higher LSTs were associated with higher N concentrations and lower C/N ratios; however, stems and buds of trees fertilized with UF were more cold-tolerant (had lower LSTs) than stems and buds on trees fertilized with CRF. Fertilizer type resulted in several differences in N and C translocation and metabolism during the fall and winter. Our results indicate trees with a similar N status are able to withstand different levels of cold depending on the rate of N and the type or form of fertilizer used during production. This may have to do with differences in how trees metabolize the different fertilizer forms, where and when the N is stored, and how it is remobilized in the spring, especially in relation to C metabolism.

In support of developing a method for removing NO(3)-N from water using denitrification, this project characterized runoff events at two nurseries in southern Florida to provide information needed for designing capacity. Specifically, estimates of runoff rates and volumes, NO(3)-N concentrations and loadings were profiled during intensively sampled fertigation events at a foliage plant nursery and a bedding plant nursery. Discharge volumes and rates varied with event, ranging from 2,487 to 20,935 L and 59.2 to 126 L.min(-1), respectively, per event. NO(3)-N concentrations ranged from 0.7 to 386.4 mg.L(-1), and event loadings ranged from 51 to 3024 g, indicating that significant losses may be realized. This project provided valuable hydraulic and chemical loading information needed for the development and design of bioremediation tools for the horticultural industry.

TI Spraying Leaves of Pear Nursery Trees with Urea and Copper Ethylenediaminetetraacetic Acid Alters Tree Nitrogen Concentration without Influencing Tree Susceptibility to Phytophthora syringae SO HORTTECHNOLOGY LA English DT Article DE defoliant; fertilizer; phosphonate; Pyrus communis ID PHOSPHORUS-ACID; FOSETYL-AL; APPLE-TREES; FRUIT ROT; CROWN ROT; ROOT-ROT; METALAXYL; ALMOND; CINNAMOMI; ALUMINUM AB Recent field observations by growers suggest that increased nitrogen (N) content in nursery trees resulting from foliar sprays with urea in the autumn increases tree susceptibility to infection by Phytophthora syringae. We investigated the effects of soil N availability and spraying pear (Pyrus communis 'OHF 97') trees with combinations of urea, chelated copper ethylenediaminetetraacetic acid (CuEDTA), and phosphonate-containing fungicides on stem N concentration and susceptibility to infection by P. syringae. Increasing soil N availability increased susceptibility to P. syringae and increased N and amino acid concentration in stems. Spraying trees with urea in the autumn increased concentrations of N and amino acids in stems and had no significant effect on tree susceptibility when stems were inoculated with P. syringae before or after urea sprays. Spraying trees with CuEDTA decreased stem N concentrations and had no significant influence on tree susceptibility to P. syringae when sterns were inoculated before or after CuEDTA sprays. These results suggest the relationship between tree susceptibility to P. syringae and tree N concentration may be specific to the form of N, delivery method, or timing of N applications. Trees had higher N concentrations in stems in November than in October and were more susceptible to P. syringae when inoculated in November, suggesting that environmental factors and increasing tree dormancy may be responsible for changes in susceptibility to the pathogen. Spraying trees with fungicides containing fosetyl-aluminum in October or November decreased tree susceptibility to P. syringae. The effects of fungicides containing fosetyl-aluminum on susceptibility were similar regardless of whether trees were sprayed or not with urea or CuEDTA, suggesting that these fungicides can be used in combination with urea or CuEDTA sprays for reducing disease severity caused by P. syringae without impacting growers' objective of increasing tree N content with urea or enhancing early defoliation with CuEDTA.

'Royal Gala' apples treated by dipping in freshly prepared aqueous sodium hypochlorite for 10 min showed moderate peel injury at the lowest treatment concentration of 150 mg.L(-1) when treated immediately after harvest, whereas no injury was observed on fruit treated at even the highest concentration of 2400 mg.L(-1) when fruit were kept at -1 degrees C for 3 months before treatment. At lower rates, rinsing fruit after treatment reduced injury on fruit dipped for 2 min, whereas after a 10-minute treatment, rinsing had no effect. Warm fruit (field heat) generally had a higher incidence of peel injury compared with fruit placed at -1 degrees C for 24 h before treatment. When 'Golden Delicious' apples were treated by dipping for 2 mm in freshly prepared aqueous solutions of sodium hypochlorite or calcium hypochlorite at an equimolar hypochlorite ion concentration of 0.008 M (600 mg.L(-1) sodium hypochlorite), treatment temperature had a greater influence on incidence of peel injury with sodium hypochlorite than with calcium hypochlorite. Analysis of nonpolar solvent-extractable epicuticular waxes indicated differences due to treatment among several extracted compounds. Microscopic examination of injured peel tissue indicated altered appearance of wax platelets. C1 ARS, USDA, Tree Fruit Res Lab, Wenatchee, WA 98801 USA.

Here we identified an endogenous piggyBac-like element (PLE), designated as PgPLE1, in the pink bollworm. A putatively intact copy of PgPLE1 (PgPLE1.1) presents the canonical features of PLE: inverted terminal repeats with three C/G residues at the extreme ends, inverted subterminal repeats, TTAA target site and an open reading frame encoding transposase with 68% similarity to IFP2. Vectorette PCR revealed large variation in the insertion sites of PgPLE1 amongst worldwide populations, indicating the potential mobility of PgPLE1. The PgPLE1 was undetectable in the genome of Pectinophora endema, implying the recent invasion of PgPLE1 after the divergence of these two closely related species.

However, some workers survived after being immersed in 0.03% PO water solution at 25 degrees C for up to 640 min. Elevated temperature of the PO water solution is needed to kill ants within a shorter time frame. At 50 degrees C and 0.13% PO concentration, total mortality was achieved with 10-min immersion for all ants, including brood and adult ants. Soil has a negative effect on the effectiveness of potassium oleate; however, such negative effect can be overcome by increasing either treatment temperature or duration of the treatment. In addition to immobilizing and lethal effect, PO repels ants. PO may have the potential to be incorporated into immersion treatment for the quarantine of imported fire ants to reduce the use of synthetic contact insecticides.

A classical biological control program was initiated in 1995, and the parasitoids Allotropa oracellae, Acerophaus coccois, and Zarhopalus debarri were imported from the US. A total of 19 972 parasitized mealybugs were shipped to China from 1996-2004, from which 15 430 wasps emerged, 12 933 of which were the three target species. Efforts to establish a mass-rearing program for the parasitoids in China failed. Five field release sites were established, and 6 020 parasitoids were released. Only 118 individuals of the three imported species were collected during establishment checks, although several wasps were collected 1-2 years after the last parasitoid release. Over 2 000 Anagyrus dactylopii, a cosmopolitan parasitoid, emerged from the parasitized mealybugs collected, a majority from the Taishan area near the site of the original introduction of O. acuta. To date the imported parasitoids have failed to establish, and natural enemies have not noticeably reduced mealybug populations.

CD4(+) T cells orchestrate adaptive immune responses and upon stimulation by antigen, naive CD4+ T cells proliferate and differentiate into various T cell subsets including T helper (Th) 1, Th2, and Th17 effector cells, and T regulatory cells (Treg). Each of the T cell subsets is characterized by distinct profiles of cytokines and carries out distinct and sometimes opposing activities. Initiated by IL-12 released from dendritic cells, the development of Th1 cells is the typical host response against the invasion of intracellular pathogens such as bacteria or viruses. Th1 cells deliver cell-mediated immunity through their secreted cytokines such as IFN-gamma, TNF-alpha, IL-1 beta, IL-2, and IL-12, and are responsible for the clearance of intracellular pathogens. Th2 cells are initiated by IL-4 and develop in response to allergens or the invasion of extracellular pathogens. Th2 cytokines include IL-4, IL-5, and IL-13, and are particularly important for allergic responses and the clearance of parasites. (C) 2009 Published by Elsevier Ltd.

Design: A total of 50 pigs weighing between 3.0 and 49.1 kg were studied. Each piglet's body composition was assessed by quantitative nuclear magnetic resonance (QMR, EchoMRI-AH small), whole-body chemical carcass analysis for lipid and water content, and dual-energy X-ray absorptiometry (DXA, Hologic QDR 4500, using infant or adult whole-body scan acquisition programs where appropriate). Twenty-five piglets (3.1-47.2 kg) were randomly selected to calibrate the QMR instrument. The remaining 25 piglets (3.0-49.1 kg) were used to validate the instrument. Results: The precision of QMR to estimate fat mass (FM), fat-free mass (FFM) and total body water (TBW) for five consecutive scans was excellent (1.3, 0.9 and 0.9%, respectively). QMR measures of FM were highly and significantly correlated with chemical carcass analyses and DXA measures (r(2) = 0.99 and r(2) = 0.98, respectively). QMR and DXA FFM results were highly correlated (R(2) = 0.99, P<0.01). TBW measures were strongly correlated between QMR and carcass analyses (R(2) = 0.99, P<0.01). QMR overestimated FM by 2% and DXA measures (using the infant and adult scan programs) overestimated FM by 15% on average. Conclusion: QMR provides precise and accurate measures of FM, FFM and TBW in piglets weighing up to 50 kg. As the piglet is considered to be an excellent model of human development, these data suggest that QMR should provide the opportunity to acquire valuable body composition data in longitudinal studies in children, which is not possible or practical with other commercially available instrumentation.

To examine the independent, competing, and interactive effects of perceived availability of specific types of media in the home and neighborhood sport facilities on adolescents' leisure-time physical activity (PA). Methods. Survey data from 34 369 students in 42 Hong Kong secondary schools were collected (2006-07). Respondents reported moderate-to-vigorous leisure-time PA, presence of sport facilities in the neighborhood and of media equipment in the home. Being sufficiently physically active was defined as engaging in at least 30 minutes of non-school leisure-time PA on a daily basis. Logistic regression and post-estimation linear combinations of regression coefficients were used to examine the independent and competing effects of sport facilities and media equipment on leisure-time PA. Results. Perceived availability of sport facilities was positively (ORboys = 1.17; ORgirls = 1.26), and that of computer/Internet negatively (ORboys = 0.48; ORgirls = 0.41), associated with being sufficiently active. A significant positive association between video game console and being sufficiently active was found in girls (ORgirls = 1.19) but not in boys. Compared with adolescents without sport facilities and media equipment, those who reported sport facilities only were more likely to be physically active (ORboys = 1.26; ORgirls = 1.34), while those who additionally reported computer/Internet were less likely to be physically active (OR boys = 0.60; ORgirls = 0.54). Conclusions. Perceived availability of sport facilities in the neighborhood may positively impact on adolescents' level of physical activity. However, having computer/Internet may cancel out the effects of active opportunities in the neighborhood. This suggests that physical activity programs for adolescents need to consider limiting the access to computer-mediated communication as an important intervention component.

TI Invasive Plant Researchers Should Calculate Effect Sizes, Not P-Values SO INVASIVE PLANT SCIENCE AND MANAGEMENT LA English DT Review DE Estimation; statistics; confidence interval; P-values; Null hypothesis significance testing ID NULL-HYPOTHESIS; STATISTICAL SIGNIFICANCE; ECOLOGY AB Null hypothesis significance testing (NHST) forms the backbone of statistical inference in invasive plant science. Over 95% of research articles in Invasive Plant Science and Management report NHST results such as P-values or statistics closely related to P-values such as least significant differences. Unfortunately, NHST results are less informative than their ubiquity implies. P-values are hard to interpret and are regularly misinterpreted. Also, P-values do not provide estimates of the magnitudes and uncertainties of studied effects, and these effect size estimates are what invasive plant scientists care about most. In this paper, we reanalyze four datasets (two of our own and two of our colleagues; studies put forth as examples in this paper are used with permission of their authors) to illustrate limitations of NHST. The re-analyses are used to build a case for confidence intervals as preferable alternatives to P-values. Confidence intervals indicate effect sizes, and compared to P-values, confidence intervals provide more complete, intuitively appealing information on what data do/do not indicate.

This expansion has, therefore, been the focus of management efforts, including the thinning or removal of trees in areas that were historically shrubland. Our study examined the effects of tree thinning at two sites located in eastern Nevada, near the center of the Great Basin. Such projects can be controversial, so our goal was to estimate and document the ecological effects of low-disturbance tree thinning at these two sites. Both sites were mechanically thinned using a feller-buncher and were aerially seeded with native grasses. Aerial seeding had no apparent effect at either site. The site that had lower tree cover before treatment (Ely, NV) showed an increase in native forbs and a small increase in invasives. The site that initially had very high tree cover and low shrub cover (Mt. Wilson, NV) showed increases in native forbs and species diversity and a substantial increase in invasives. We conclude that low-disturbance methods for thinning encroaching trees can have positive ecological effects in shrublands but that the initial cover of both trees and native herbaceous species should be considered to determine the potential of the site to recover naturally from the seedbank and the risk of invasion by downy brome.

Recent research suggests fast-growing species might have a greater ability to allocate root biomass to nutrient-rich microsites (root foraging precision) than slow-growing species. We examined if differences in relative growth rate (RGR) between invasive and native species were related to differences in foraging precision. We hypothesized that invasive species would: (1) have greater foraging precision than native species but (2) greater foraging precision would come at a cost in terms of root nutrient uptake rate. Foraging precision was evaluated on plants growing in soils with uniform or patchy nutrient distribution. Plants were harvested at a common time and a common developmental stage to separate indirect effects of RGR on foraging. Nutrient uptake rate was examined by exposing plants to a low or high nitrogen pulse. Invasives foraged more precisely than natives but had lower nitrogen uptake rate. Although these results support the idea of a positive relationship between RGR and foraging precision, biomass production in heterogeneous soils showed no relationship to foraging precision. Instead, species with greater RGR produced more biomass and root length across all treatments, allowing greater nutrient capture in heterogeneous soils. Although these results do not exclude a role for proliferation in influencing invasion of nutrient-poor systems or the potential for heterogeneity to influence population processes, these results suggest other traits may have an overriding importance in determining invader success in these systems.

GROWTH AND EVAPOTRANSPIRATION SO IRRIGATION AND DRAINAGE LA English DT Article DE greenhouse; water use efficiency; yield; salt tolerance ID SALT TOLERANCE; YIELD; WATER; GERMINATION; QUALITY; MODEL; NACL AB The effects of irrigation water salinity on eggplant growth, yield, water consumption and mineral matter accumulation in leaves and fruits were investigated with a greenhouse experiment. For this purpose, five saline irrigation waters with electrical conductivities of 1.5, 2.5, 3.5, 5.0, 7.0 dS m(-1) and tap water as a control treatment were utilized. Throughout the experiment, the amounts of irrigation water to be applied were determined based on the weight changes of each pot. After irrigation the amount of drainage water volume was measured in drain pans placed underneath each pot. We calculated the plant water consumption from the water budget information. Threshold soil salinity and slope values of the yield response to soil salinity level were determined as <1.5 dS m(-1) and 4.4 respectively for fruit yield and 6.7 dS m(-1) and 3.7 for the vegetative dry weight. The fruit yield results revealed that eggplant was moderately sensitive to salinity. Plant water consumption and water use efficiency decreased with increasing salinity. The crop yield coefficient (K-y) was 2.3. Salinity caused a decrease in K content, and increased Cl content of leaves. Although mineral concentration of the leaves did respond to increased mineral concentration of irrigation water, mineral concentration of fruits did not. Copyright (C) 2008 John Wiley & Sons, Ltd.

Beef loin, pork loin, chicken breast, pollock fillet, and salmon fillet were evaluated for composition, protein digestibility, and AA bioavailability using the immobilized digestive enzyme assay, cecectomized rooster assay, and ileally cannulated dog assay. Pollock contained the greatest amount of CP, total essential AA (TEAA), and total nonessential AA (TNEAA; DM basis; 96.9, 38.6, and 50.3%, respectively). Salmon contained the next greatest amounts ( 92.8, 36.4, and 44.6%), followed by chicken (90.3, 36.1, 43.2%). Beef had the least CP content (82.7%), but had slightly greater TEAA and TNEAA concentrations (33.9, 42.0%) compared with pork (86.2, 33.6, 41.3%). Immobilized digestive enzyme assay values were greatest for pollock fillet (0.71) and least for chicken breast (0.52). Beef loin, pork loin, and salmon fillet were similar (0.63, 0.62, and 0.64, respectively). Standardized TEAA and TNEAA digestibility coefficients, evaluated using the cecectomized rooster assay, were greatest (P < 0.05) for pollock fillet (90.4 and 89.8%, respectively) and least (P < 0.05) for chicken breast (86.6 and 85.9%, respectively) and salmon fillet (87.8 and 86.4%, respectively). Dogs assigned to a 5 x 5 Latin square design were fed 5 diets, with each test substrate as the major protein source. No significant differences (P > 0.05) were found in ileal digestibility of protein. Values ranged from 88.9% for chicken to 90.5% for pork loin and pollock fillet. Ileal TEAA and TNEAA coefficients were not different among test substrates, with values between 91.7 and 92.7%, and 88.8 and 90.4%, respectively. Total tract CP apparent digestibility values ranged from 94.4 to 94.8%, with no differences noted among treatments. Despite marked differences in composition and predicted and standardized digestibility values, when the protein sources were added to diets at a concentration of approximately 30% (25% of total energy intake), no differences in test protein substrates were noted in either ileal or total tract nutrient digestibility.

TI Fate and transport of zoonotic, bacterial, viral, and parasitic pathogens during swine manure treatment, storage, and land application SO JOURNAL OF ANIMAL SCIENCE LA English DT Article; Proceedings Paper CT Beef Symposium on Population Data Analyses to Evaluate Trends in Animal Production Systems CY JUL 12-16, 2009 CL Montreal, CANADA SP Amer Soc Anim Sci, Amer Dairy Sci Assoc, Canadian Soc Anim Sci DE manure application; manure storage; manure treatment; swine manure; zoonotic pathogen ID HEPATITIS-E VIRUS; INFLUENZA-A VIRUSES; ESCHERICHIA-COLI; UNITED-STATES; YERSINIA-ENTEROCOLITICA; GIARDIA-INTESTINALIS; PORCINE ROTAVIRUSES; ASCARIS-SUUM; MOLECULAR CHARACTERIZATION; MICROBIAL-POPULATIONS AB Members of the public are always somewhat aware of foodborne and other zoonotic pathogens; however, recent illnesses traced to produce and the emergence of pandemic H1N1 influenza virus have increased the scrutiny on all areas of food production. The Council for Agricultural Science and Technology has recently published a comprehensive review of the fate and transport of zoonotic pathogens that can be associated with swine manure. The majority of microbes in swine manure are not zoonotic, but several bacterial, viral, and parasitic pathogens have been detected. Awareness of the potential zoonotic pathogens in swine manure and how treatment, storage, and handling affect their survival and their potential to persist in the environment is critical to ensure that producers and consumers are not at risk. This review discusses the primary zoonotic pathogens associated with swine manure, including bacteria, viruses, and parasites, as well as their fate and transport. Because the ecology of microbes in swine waste is still poorly described, several recommendations for future research are made to better understand and reduce human health risks. These recommendations include examination of environmental and ecological conditions that contribute to off-farm transport and development of quantitative risk assessments. C1 [Ziemer, C.

SO JOURNAL OF APPLIED ECOLOGY LA English DT Article DE Curculionidae; Eichhornia crassipes; herbivory; host plant quality; insect reproduction; leaf nitrogen; Neochetina bruchi; Neochetina eichhorniae; nutrient flux; plant-animal interactions ID CRASSIPES MART SOLMS; BIOLOGICAL-CONTROL AGENT; SALVINIA-MOLESTA MITCHELL; FLOATING WEED SALVINIA; EICHHORNIA-CRASSIPES; NEOCHETINA-EICHHORNIAE; LAKE VICTORIA; TOP-DOWN; COLEOPTERA-CURCULIONIDAE; PISTIA-STRATIOTES AB P>1. Nutrient availability varies widely in aquatic systems and is likely to profoundly affect the outcomes of plant-herbivore interactions in aquatic environments. This has implications in programmes aimed at the biological control of water weeds. We hypothesized that nutrient flux seasonally affects ovarian development of two specialist weevil species, Neochetina eichhorniae and Neochetina bruchi, thereby influencing population growth on the floating plant Eichhornia crassipes. 2. We also hypothesized that the weevils differed in their sensitivities to nutritional quality and interacted differently depending on host quality. 3. To test these hypotheses, we cultured E. crassipes plants under 20 fertilizer regimens then introduced reproductively dormant, over-wintering female weevils as single or mixed species populations. They were later retrieved and dissected to ascertain ovarian status. F-1 progeny was extracted biweekly to compare fecundity with population growth. 4. Ovaries regained functionality and the reproductive proportion of the population increased with fertilizer rate as did the fecundity of reproductive individuals. F-1 progeny increased exponentially from 7 to over 300 weevils tank-1 in the highest fertilizer treatment. 5. Mixed species treatments produced more offspring under high fertilizer rates than single species treatments (236 +/- 32 mixed vs. 155 +/- 25 N. bruchi or 170 +/- 33 N. eichhorniae pure). Neochetina eichhorniae was more productive throughout than N. bruchi, but N. bruchi performed nearly as well in high fertilizer treatments. 6. Ratios of the two species remained consistent whether in single or mixed species populations suggesting a lack of interspecific interference. However, N. eichhorniae seemed more adaptable to a wider range of plant quality and more tolerant of lower nutritional circumstances. 7. Synthesis and applications. The coupling of reproductive status of the parental generation with the population response of the F-1 generation indicates that plant quality drives population growth of both weevil species, demonstrating bottom-up regulation. This largely explains the variable performance of these weevils as biological control agents. These results emphasize the importance of considering bottom-up regulation in evaluating host range trials, predicting efficacy and in post-release evaluations. In addition, they suggest that partial herbicide treatments to accomplish phased removal of infestations could enhance the quality of the remaining plants, thereby better integrating biological control into current E. crassipes management systems.

LEPIDOPTERA; W-CHROMOSOME AB The codling moth Cydia pomonella (L.) (Lepidoptera Tortricidae) is a key pest of pome fruit (apple, pear and quince) and walnut orchards in most temperate regions of the world. Efforts to control the codling moth in the past mostly relied on the use of broad spectrum insecticide sprays, which has resulted in the development of insecticide resistance, and the disruption of the control of secondary pests. In addition, the frequent reliance and use of these insecticides are a constant threat to the environment and human health. Consequently, there have been increased demands from the growers for the development of codling moth control tactics that are not only effective but also friendly to the environment. In that respect, the sterile insect technique (SIT) and its derivative, inherited sterility (IS), are, together with mating disruption and granulosis virus, among the options that offer great potential as cost-effective additions to available control tactics for integration in area-wide integrated pest-management approaches. In support of the further development of the SIT/IS for codling moth control, the Joint FAO/IAEA Programme of Nuclear Techniques in Food and Agriculture implemented a 5-year Coordinated Research Project (CRP) entitled 'Improvement of codling moth SIT to facilitate expansion of field application'. Research focussed on sterile codling moth quality and management (e.g. mobility and life-history traits in relation to rearing strategy, dispersal, flight ability, radiosensitivity and mating compatibility) and a better understanding of the basic genetics of codling moth to assist the development of genetic sexing strains (e.g. cytogenetics, the development of dominant conditional lethal mutations, molecular characterization of the sex chromosomes, sex identification in embryos and cytogenetic markers). The results of the CRP are presented in this special issue. C1 [Vreysen, M. J. B.] IAEA, Labs Seibersdorf, Entomol Unit,Joint FAO IAEA Programme, FAO,Agr & Biotechnol Lab, A-1400 Vienna, Austria.

TI Compatibility of codling moths Cydia pomonella (Linnaeus) (Lepidoptera: Tortricidae) from South Africa with codling moths shipped from Canada SO JOURNAL OF APPLIED ENTOMOLOGY LA English DT Article DE Mass rearing; mating behaviour; sterile insect technique ID OLETHREUTIDAE AB The sterile insect technique (SIT) has been successfully applied against codling moth Cydia pomonella (Linnaeus) (Lepidoptera; Tortricidae) in British Columbia since 1992 where the mass-rearing facility produces between 15 and 16 million moths per week. Due to the seasonality of this pest, the facility is only fully utilized for part of the year. The time and expense of implementing SIT against codling moth in South Africa may be substantially reduced if moths from Canada were sexually compatible with those from South Africa. In addition, because the pome fruit-growing season in both countries is opposite, the programme in Canada might benefit by maintaining moth production year-round and selling moths to South Africa. Semi-field studies in small cages and release-recapture studies were conducted in an unsprayed apple orchard in South Africa to assess mating compatibility of laboratory-reared codling moth from Canada and wild codling moths from South Africa. The results suggest that Canadian codling moth males were equally attracted to calling Canadian and South African females despite the fact that Canadian moths had been transported (from Canada to South Africa) for 48 h as both pupae and adults. The data also suggest that at lower field temperatures Canadian moths were more active than South African moths. Results from the release-recapture field trials indicated that Canadian and South African males were equally attracted to Canadian and South African females. These results suggest that codling moths from Canada and South Africa are fully compatible and indicate that Canadian moths can be used for SIT studies in South Africa. As these studies were conducted with moths from two very different climatic and time zones, it is proposed that populations of codling moth in other pome fruit production areas may also be compatible with the Canadian moths.

Development of resistance to insecticides and placement of restrictions on the use of certain insecticides has made control of codling moth in South Africa increasingly problematic. The use of the sterile insect technique (SIT) as a control tactic for codling moth is under investigation as a potential addition to the current control strategy. We investigated the radiosensitivity of a laboratory strain of codling moth that was established from moths collected from commercial and organic orchards in the Western Cape, South Africa. Fecundity and fertility of this strain following radiation were consistent with values for the codling moth strain in the Canadian rearing facility in British Columbia. For both strains, the female codling moth was considerably more radiosensitive than the male. At a radiation dose of 100 Gy or higher, treated females were 100% sterile. The fertility of the South African strain was higher (86.3%) than for the Canadian strain (71.9%). This difference in fertility between the two strains was maintained when the dose of radiation was 100 Gy. However, the level of fertility was very similar between the two strains for doses >= 150 Gy. Therefore, based upon previously published work and the data from this study, an operational dose of 150 Gy is recommended for future codling moth SIT programmes in South Africa. C1 [Blomefield, T.

In an effort to reduce the use of pesticides to control this pest, the sterile insect technique (SIT) is used or considered for use as a component of area-wide integrated pest management programmes. Rearing codling moths through diapause has been shown to improve the competitiveness of sterile moths released in orchards, and provides management alternatives that would allow mass-rearing facilities to increase their yearly production of sterile moths. Because radiosensitivity in insects can be influenced by numerous biological factors, laboratory tests were conducted to examine whether the response to increasing doses of radiation, as expressed in the fecundity and fertility of cohorts of moths, is similar for adult moths mass-reared through diapause or through standard (non-diapause) production protocols. Our data revealed that the effect of increasing doses of radiation on fecundity and fertility of codling moths reared through both rearing strategies was similar. In the case of fertility, this is a particularly important finding for the expanded application of codling moth SIT. If mass-rearing facilities use year-round diapause rearing, the dose required to treat the insects prior to release will be similar to that used when codling moths are reared through standard production protocols.

This does not lead to environmentally sustainable control and farmers are demanding alternative control tools which are both effective and friendly to the environment. The sterile insect technique (SIT), within an area-wide integrated pest management (AW-IPM) approach, has proven to be a powerful control tactic for the creation of pest-free areas or areas of low pest prevalence. Improving the quality of laboratory-reared moths would increase the efficacy of released sterile moths applied in AW-IPM programmes that integrate the (SIT). Factors that might affect the quality and field performance of released sterile moths are identified and characterized in this study. Some tools and methods to measure, predict and enhance moth quality are described such as tests for moth quality, female moth trapping systems, 'smart' traps, machine vision for recording behaviour, marking techniques, and release technologies. Methods of enhancing rearing systems are discussed with a view to selecting and preserving useful genetic traits that improve field performance. C1 [Simmons, G.

Such tritrophic interactions have been examined thoroughly in the above-ground terrestrial environment. Recently, similar signals have also been described in the subterranean environment, which may be of equal importance for indirect plant defense. The larvae of the root weevil, Diaprepes abbreviates, are a serious pest of citrus. Infestations can be controlled by the use of entomopathogenic nematodes, yet the interactions between the plant, insect and nematode are poorly understood and remain unpredictable. In bioassays that used a root zone six-arm olfactometer, citrus roots ('Swingle citrumelo' rootstock) recruited significantly more entomopathogenic nematodes (Steinernema diaprepesi) when infested with root weevil larvae than non-infested roots. Infested plants were more attractive to nematodes than larvae alone. Roots damaged by weevil larvae attracted more nematodes than mechanically damaged roots and sand controls. By dynamic in situ collection and GC-MS analysis of volatiles from soil, we determined that four major terpene compounds were produced by infested plant roots that were not found in samples from non-infested roots or soil that contained only larvae. Solvent extracts of weevil-infested roots attracted more nematodes than extracts of non-infested roots in a two choice sand-column bioassay. These findings suggest that Swingle citrus roots release induced volatiles as an indirect defense in response to herbivore feeding, and that some of these induced volatiles function as attractants for entomopathogenic nematodes.

Extractable amounts of brood pheromone were not significantly different by larval population; however, differences in the proportions of components enabled us to classify larval population of 77% of samples correctly by discriminant analysis. Honeybee releaser and primer pheromone responses to USA,Africanized and-European pheromone blends were tested. Texas-Africanized and Georgia-European colonies responded with a significantly greater ratio of returning pollen foragers when treated with a blend from the same population than from a different population. There was a significant interaction of pheromone blend by adult population source among Georgia-European bees for modulation of sucrose response threshold, a primer response. Brood pheromone blend variation interacted with population for pollen foraging response of colonies, suggesting a self recognition cue for this pheromone releaser behavior. An interaction of pheromone blend and population for priming sucrose response thresholds among workers within the first week of adult life suggested a more complex interplay of genotype, ontogeny, and pheromone blend.

Sequence typing revealed that the isolates were nearly evenly divided among the Fusarium solani species complex (FSSC; n = 18), the F. oxysporum species complex (FOSC; n = 20), and the Gibberella (Fusarium) fujikuroi species complex (GFSC; n = 20). The three-locus typing scheme used for members of the FSSC identified 18 novel STs distributed among six phylogenetically distinct species, yielding an index of discrimination of 1.0. Phylogenetic analysis of the FOSC two-locus data set identified nine STs, including four which were novel, and nine isolates of ST 33, the previously described widespread clonal lineage. With the inclusion of eight epidemiologically unrelated ST 33 isolates, the FOSC typing scheme scored a discrimination index of 0.787. The two-locus GFSC typing scheme, which was primarily designed to identify species, received the lowest discrimination index, with a score of 0.492. The GFSC scheme, however, was used to successfully identify 17 isolates as F. verticillioides, 2 as F. sacchari, and 1 as F. guttiforme. This is the first report that F. guttiforme causes a human mycotic infection, which was supported by detailed morphological analysis. In addition, the results of a pathogenicity experiment revealed that the human isolate of F. guttiforme was able to induce fusariosis of pineapple, heretofore its only known host.

Using social cognitive career theory (Lent, Brown, & Hackett, 1994), we examined the relationships of social cognitive variables (math/science academic self-efficacy, math/science outcome expectations) as well as the influence of ethnic variables (ethnic identity, other-group orientation) and perceptions of campus climate to students' math/science interests and goal commitment to earn a BIO/ENG degree. Path analysis revealed that the hypothesized model provided good overall fit to the data, revealing significant relationships between outcome expectations and interests and between outcome expectations and goals. Paths from academic self-efficacy to BIO/ENG goals and from interests to BIO/ENG goals varied for students in engineering and the biological sciences. For both groups, other-group orientation was positively related to self-efficacy, and support was found for an efficacy-mediated relationship between perceived campus climate and goals. Theoretical and practical implications of the study's findings are considered as well as future research directions.

Sixty Alpine goats without evidence of clinical mastitis were assigned to 3 groups with milk SCC level of <500,000 (low), 500,000 to 1,000,000 (medium), and 1,000,000 to 1,500,000 (high) cells/mL. Thirty kilograms of goat milk with mean SCC levels of 410,000 (low), 770,000 (medium), and 1,250,000 (high) cells/mL was obtained for the manufacture of semisoft cheese for 2 consecutive weeks in 3 lactation stages. The composition of milk was analyzed and cheese yield was recorded on d 1. Cheese samples on d 1, 60, and 120 were analyzed for total sensory scores, flavor, and body and texture by a panel of 3 expert judges and were also analyzed for FFA. Results indicated that milk composition did not change when milk SCC varied from 214,000 to 1,450,000 cells/mL. Milk with higher SCC had a lower standard plate count, whereas coliform count and psychrotrophic bacteria count were not affected. However, milk components (fat, protein, lactose, casein, and total solids) among the 3 groups were similar. As a result, no significant differences in the yield of semisoft goat cheeses were detected. However, total sensory scores and body and texture scores for cheeses made from the high SCC milk were lower than those for cheeses made from the low and medium SCC milks. The difference in milk SCC levels also resulted in diverse changes in cheese texture (hardness, springiness, and so on) and FFA profiles. Individual and total FFA increased Significantly during ripening, regardless the SCC levels. It is concluded that SCC in goat milk did not affect the yield of semisoft cheese but did result in inferior sensory quality of aged cheeses. C1 [Chen, S. X.; Wang, J. Z.; Zeng, S.

Water samples were collected in triplicate from the north, south, east, and west quadrants of each body of water. The mean (+/- SEM) winter dairy lagoon endotoxin concentration was significantly higher (9,678 +/- 1,834 ng/mL) than the summer concentration (3,220 +/- 810 ng/mL). The mean endotoxin concentration of the 2 control lakes (summer: 58.1 +/- 8.8 ng/mL; winter: 38.6 +/- 4.2 ng/mL) was significantly less than that of the dairy lagoons. Two hundred-one Salmonella enterica spp. isolates were identified, 7 serovars were recovered from the dairy lagoons, and 259 Salmonella ssp. were identified from 5 other dairy locations (milk barn, ditch effluent, settling basin, feed alley pad flush, and center pivots). Twenty-eight Salmonella spp. were identified from center pivot water. Escherichia coli O157:H7 pathogens were isolated from other dairy locations but not from lagoons. Neither Salmonella spp. nor E. coli 0157:H7 were identified from control lakes. Enterobacteriaceae opportunistic pathogens were isolated from both dairies and control lakes. Important mesophilic and thermophilic catabolic (to manure biosolids) fungal isolates were identified from dairy effluent locations, but no thermophilic fungal isolates were cultured from the control lakes. Adequate curing of green forage following center pivot irrigation is important to kill lagoon water enteric pathogens, even though the lagoon water is mixed with fresh water. Recirculating lagoon water to flush the feed alley pad, where cows stand while eating, to remove manure and using lagoon water to abate dairy dust in loafing pens and unimproved dairy roads is inconsistent with good environmental practice management.

After all edits, 25,809 tests from 21,514 Holstein cows in 282 Johne's positive herds were available for analysis. The Johne's test results were analyzed both as a binary trait (positive or negative) and as a linear trait as the transformed ELISA optical density [ln(OD)]. Significant fixed effects in the model were age at test date, days in milk, and laboratory negative control; random effects were herd test date, animal effect, and permanent environment effect. Transformed ELISA optical density increased with age at test day and days in milk. Heritability estimates ranged from 0.065 to 0.095. Percentage of variation explained by maternal effects ranged from 1.3 to 2.29%. Repeatabilities ranged from 0.380 to 0.433. Statistically significant correlations between the sire solutions for ln(OD) for 154 bulls with at least 30 daughters in the analysis and their USDA predicted transmitting abilities were as follows: fat yield, -0.199; protein yield, -0.179; productive life, -0.292; and Net Merit, -0.339. These correlations suggest that selection for productive life or Net Merit also will improve resistance to Johne's disease. C1 [Attalla, S. A.; Seykora, A. J.; Heins, B.

We examined vascular functional responses in mesenteric arteries from Cu-deficient Sprague-Dawley rat dams and from offspring directly exposed to maternal Cu deficiency during development and lactation and perpetuation of the effects in a second generation of offspring. Dams were fed a diet with marginal (1 mg Cu/kg) or adequate (6 mg Cu/kg) Cu for 3 weeks before conception and throughout pregnancy and lactation periods. Half of the first generation (F1) litters were cross-fostered. At reproductive maturity, F1 pairs were bred within groups resulting in second generation (F2) offspring. At 9 weeks of age, mesenteric artery (200mm) isometric tension was determined in response to vasoconstrictors and vasorelaxants using a small artery wire myograph. Cu deficiency did not alter the vascular function in dams. In F1 offspring, increased responsiveness to potassium chloride in male offspring was due to direct exposure to maternal Cu deficiency in the birth mother, while enhanced endothelium-dependent relaxation responses in female offspring resulted from postnatal exposure to maternal Cu deficiency. Increased endothelium independent and decreased endothelium-dependent relaxation responses were identified in F2 Cu-deficient male offspring. These data indicate that exposure to maternal Cu deficiency during critical windows of development alter the vascular function across two generations of offspring. C1 [Anderson, C.

TI Evidence for Role of White-Tailed Deer (Artiodactyla: Cervidae) in Epizootiology of Cattle Ticks and Southern Cattle Ticks (Acari: Ixodidae) in Reinfestations Along the Texas/Mexico Border in South Texas: A Review and Update SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Review DE Rhipicephalus; Boophilus annulatus; Boophilus microplus; white-tailed deer; cattle fever tick AB From 1907 when the fever tick eradication campaign began until 1933, the tick eradication methods of dipping cattle in an acaricide or "pasture vacation" were enormously successful in eradicating southern cattle ticks [Rhipicephalus (Boophilus) microplus (Canestrini) J, until failures began to occur in some areas of Florida. Regarding the failures in Florida, the consensus was that populations of white-tailed deer [Odocoileus virginianus (Zimmermann)] infested with southern cattle ticks were responsible. After numerous deer in several counties were killed, eradication was achieved in Florida. As in Florida, in Texas increasing numbers of failures of the pasture vacation approach to tick eradication from the 1970s to the present are known to be related to the abundance of white-tailed deer and perhaps other wild ungulate species. A sizable body of evidence confirms the hypothesis that white-tailed deer support the dispersal and maintenance of both cattle ticks I Blinncephatus (Boophilus) annulatus (Say)] and southern cattle ticks (cattle fever ticks) within the permanent quarantine or buffer zone in South Texas along the Rio Grande, as well as in the so-called free ("cattle fever tick-free") area north and east of the buffer zone and extending to the east coast of the United States. As of August 2009, in addition to the permanent quarantine zone of ----2,233 km2, three temporary preventative or blanket quarantines were established. Currently, only two methodologies exist to control ticks feeding on white-tailed (leer: 1) a systemic treatment method involving dispersal of iverinectin-medicated corn, Zea mays L.; and 2) two topical treatment methods, 4-poster' (leer treatment bait stations and '2-poster' deer treatment feeder adapters, both of which passively apply topically active acaricide to deer for the eradication of populations of cattle fever tick associated with white-tailed deer. This study presents and summarizes confirmational support for the role of white-tailed deer derived from historical accounts, circumstantial evidence from review of recent infestations, and cattle fever tick infestations on white-tailed deer that were live-captured and examined specifically for cattle fever ticks.

TI Interrupted Incubation and Short-Term Storage of the Alfalfa Pollinator Megachile rotundata (Hymenoptera: Megachilidae): A Potential Tool for Synchronizing Bees With Bloom SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE low-temperature tolerance; stress; emergence; post emergence longevity ID SARCOPHAGA-CRASSIPALPIS; DROSOPHILA-MELANOGASTER; COLD-STORAGE; FLESH FLY; TOLERANCE; INSECTS; STRESS AB A useful technique for synchronizing pollinators with the alfalfa. Medicago savita L. (Fabaceae), bloom is to interrupt the late spring incubation of developing bee pupae and pharate adults of Megachile rotundata (F.) (Hymenoptera: Megachilidae) with short-term low-temperature storage. However, low-temperature exposure can be stressful depending on the temperature, duration of exposure, and the developmental stage exposed. To evaluate the effect of low-temperature storage after development had already been initiated by exposure to 29 degrees C, three developmental stages (eye pigment pupae, body pigment pupae, and pharate adults ready to emerge) were exposed to 6, 12, or 18 degrees C for durations up to 28 d. The effect of delaying the termination of overwintering storage (6 C) from April to July ("April bees and "July bees," respectively) also was examined. The following observations were made: 1) All developmental stages of the April bees and July bees examined can be stored without harmful effects, as measured by percentage of survival, for 14 d at 12 C and above. 2) Postponing the termination of overwintering storage at 6 degrees C from April until July significantly decreased the mean number of days to 95% adult emergence in the July ready-to-emerge bees across the three temperatures tested. 3) The increase of overwintering duration also caused a decrease in the postemergence longevity of the ready-to-emerge adults stored at 6 degrees C for 14 d. 4) Of the three storage temperatures examined, 18 degrees C seems to be the optimal storage temperature for short-term storage of developing bees because of their slow but continuing development without increased mortality either during storage or after emergence.

TI Inundative Release of Aphthona spp. Flea Beetles (Coleoptera: Chrysomelidae) as a Biological "Herbicide" on Leafy Spurge in Riparian Areas SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE leafy spurge; Aphthona; biological control; riparian area; inundative release ID BIOCONTROL AGENT; EUPHORBIA-ESULA; INVASIVE WEED; COMMUNITIES; GRASSLANDS; GLYPHOSATE; RANGELAND; TOXICITY; EFFICACY; ZONES AB Inundative releases of beneficial insects are frequently used to suppress pest insects but not commonly attempted as a method of weed biological control because of the difficulty in obtaining the required large numbers of insects. The successful establishment of a flea beetle complex, mixed Aphthona lacertosa (Rosenhauer) and Aphthona nigriscutus Foundras (87 and 13%, respectively), for the control of leafy spurge, Euphorbia esula L., provided an easily collectable source of these natural enemies that enabled us to attempt inundative release as a possible leafy spurge control method in a sensitive riparian ecological zone where chemical control is restricted. Our target weed populations were small isolated patches of leafy spurge along three streams in southwestern, central, and northeastern Idaho. This study assessed leafy spurge and associated vegetation responses to inundative releases of 10 and 50 beetles per spurge flowering stem over two consecutive years. Releasing 10 beetles per flowering stem had inconclusive effects on spurge biomass, crown, stern, and seedling density. Alternatively, releasing 50 beetles per flowering stem resulted in a reduction of biomass, crown and stem density in the range of 60-80% at all three study sites, and about an approximate to 60% reduction of seedling density at one site, compared with untreated plots. In contrast to leafy spurge, associated vegetation did not conclusively respond to beetle release, indicating that it may take more than two years for desired riparian vegetation to respond to reductions in leafy spurge competition.

TI Can a Specialist Parasitoid, Macrocentrus cingulum (Hymenoptera: Braconidae), Influence the Ecotype Structure of Its Preferred Host Ostrinia nubilalis (Lepidoptera: Crambidae)? SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE ecotype; Ostrinia nubilatis; parasitoid; synchronization ID EUROPEAN CORN-BORER; GRANDII HYMENOPTERA; LARVAL PARASITOIDS; PYRALIDAE; PENNSYLVANIA; POPULATIONS AB Synchronization between a parasitoid and its preferred host is an essential strategy for successful biological control. Two ecotypes of Ostrinia nubilatis (Hubner) (Lepidoptera: Crambidae) in North America are distinguished by their voltinism. In this study, the differential impact of a specialist parasitoid, Macrocentrus cingulum Brischke (Hymenoptera: Braconidae), on the univoltine and multivoltine populations of 0. nubilatis is investigated. Four years of field and laboratory study suggested that M. cingulum emergence was synchronized with the spring emergence of the multivoltine ecotypes of O. nubilatis in Pennsylvania. Univoltine populations experienced minimal parasitism from M. cingulton. Field-collected data suggested that the postdiapause multivoltine O. nubitalis field population was male biased, whereas the univoltine population was female biased. M. cingulum-parasitized postdiapause 0. nubilatis larvae were significantly heavier than the male and noriparasitized female larvae. Sex ratio differences observed in overwintered 0. nubilatis populations in the presence or absence of M. cingulum parasitism suggested preferential parasitism between male and female 0. nubilatis larvae. Correlation between the larger parasitized 0. nubilalis larval host and the number of adult parasitoids emerging per host suggested a potential evolutionary advantage to parasitizing female or larger hosts.

The development of CATTS treatments is expensive and time-consuming. For a more rapid assessment of different species and life stages' tolerances to heated controlled atmospheres, the controlled atmosphere water bath (CAWB) system can be used to help advance the development of CATTS treatments for pests. The CAWB system was used to test the response of eggs and larval stages of Thamnatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae). Eggs and larvae at different developmental stages were treated under regular air and a modified controlled atmosphere of 1% O(2)., and 15% CO(2) at two ramping heat rates: 12 and 24 degrees C/h. Typically the faster heat rate and modified atmosphere reduced treatment times required to control the different life stages. T. leucotreta larvae were more tolerant of the treatments than eggs. The most tolerant life stage was the fourth instar. Effective treatments against the most tolerant life stage determined by the CAWB system can now be used to develop CATTS technology against T. leucotreta. Further research will focus on developing CATS treatments using infested fruit to determine effective treatments that maintain fruit quality. C1 [Johnson, S.

Planococcus ficus Signoret (Hemiptera: Pseudo-coccidae), on dormant grape ( Vitis spp.) benchgrafts. At 30 ppm oxygen, 3-d ULO treatment at 25 degrees C and 4-d ULO treatment at 15 degrees C achieved complete control of all life stages of P. ficus. At a much lower oxygen level (<1 ppm), the two ULO treatments with the same exposure periods of 3 d at 25 degrees C and 4 d at 15 degrees C were tested on six table and wine grape cultivars grafted on rootstocks along with P. ficus. The benchgrafts were then potted in a greenhouse, together with untreated controls, to determine treatment effects on rootstock viability. Both ULO treatments achieved complete control of P. ficus and did not have any negative effects on vine growth, compared with the control. Results indicate that ULO treatments can be used to control P.ficus on dormant grape benchgrafts. The advantages of the ULO treatments are also discussed with respect to hot water treatments.

China annually exports to the United States significant quantities of bamboo garden stakes (Bambusa spp.). In recent years, Plant Protection and Quarantine officers of the U.S. Department of Agriculture-Animal and Plant Health Inspection Service have made numerous interceptions of the bamboo borer, Chlorophorus annularis Fairmaire (Coleoptera: Cerambycidae), in bamboo products from China. This species is considered to have high pest risk potential in the trade of bamboo products. As a fumigant, sulfuryl fluoride (SF) would be a practical alternative to methyl bromide (MeBr) fumigation. Here, we report the results of SF fumigation tests for C. annularis in bamboo poles at three doses-96 g/m(3) at 15.9 degrees C, 80 g/m(3) at 21.5 degrees C, and 64 g/m(3) at 26.0 degrees C in glass test chambers. Commercial standard fumigations were also conducted in a standard 6.1-m-long, 33.2-m(3) (standard height, 20-feet) marine general cargo container loaded to 80% (vol:vol) with similar bamboo poles, and sufficient levels of SF were obtained during the 24-h fumigations. During the course of these tests, 2,424 larvae, 90 pupae, and 23 adults in total were killed, with no survivors. A treatment schedule using SF is proposed for bamboo as an alternative to MeBr at several temperatures tested.

Monitoring programs were conducted from 2003 to 2006 on seven blueberry farms to determine the relative abundance of this leafminer by using pheromone-baited traps and by sampling vegetative and flower/fruit clusters and new shoot growth. We found at least three distinct generations per year, with populations reaching their highest peak in the second generation. Laboratory studies characterized the life history of C. porphyretica and its parasitoid Pholetesor sp. prob. salalicus (Mason). The developmental period of C. pomhyretica, from egg to adult, took 927, 838, and 912 degree-days (DD) at 20, 25, and 30 degrees C, respectively, by using a developmental threshold of 4.8 degrees C. This was equivalent to an average of 892 DD to complete development to adult, which compared with 870 and 880 DD between the first and second, and second and third generations, respectively, by using pheromone trap data averaged from 2004 to 2006. Although C. porphyretica populations varied greatly, the number of larvae in cluster and new shoot samples was highly correlated with the number of adults in traps. Field parasitism rate was approximate to 29% with the praconid Pholetesor sp. the most abundant parasitoid. Ten of the 13 parasitoid species collected belonged to the family Eulophidae. When different ages of leafminers were exposed to Pholetesor sp., we found that the parasitoid attacks 9-15-d-old instars that reside in the mines of leaves.

Little is known about the field biology of this pest. Simple prediction models, such as degree-day models, are an integral tool for development of C. adspersus management strategies. Using data collected in Colorado. Kansas, and Nebraska, we sought for predictable variation between C. adspersus pupation, adult eclosion, and emergence and accumulated degree-days Celsius (DD) by using a temperature threshold of 5 C. Accurate phenological models can be used to time scouting efforts and pesticide applications. The relationship between phenological data and accumulated DD fit nonlinear, Gaussian distributions better than uniform distributions. Phenological models were developed to describe these distributions for pupation, adult presence within the stalk and adult emergence. The pupation model predicts 50% pupation at 197 DD and 90% at 307 DD. Model results predict that 50% of adult eclosion within the stalks will have transpired at 396 DD and 90% at 529 DD. A model-averaged result from two data sets predicts 5% adult emergence from stalks at 262 DD, 50% emergence at 540 DD, 75% emergence at 657 DD, and 90% at 777 DD. Scouting for adults thus can be initiated at 262 DD. Current chemical controls target adults to prevent oviposition. Thus, applications therefore should not be made before this point.

The blend consisted of (.11Z,13Z)-hexadecadienal; (11Z,13Z)-hexadecadien-1-ol; (11Z,13E)-hexadecadien-1-ol; and a hydrocarbon, (3Z,6Z,9Z,12Z,15Z)-tricosapentaene (C23 pentaene), in ratios of,approximate to 100:100:5:5. Other minor components of pheromone gland extracts included (11Z,13E)-hexadecadienal; (11E,13Z)hexadecadienal; (11Z,13Z)-hexadecadien-1-y1 acetate; (Z)-11-hexadecenal; hexadecanal: hexadecan-1-ol; and a second pentaene, (346Z,9Z,12Z,15Z)-penta.cosapentaene (C25 pentaene). These minor components did not increase attraction of male navel orangeworm to the basic four-component blend. The use of another, cross-attracted pyralid moth, Pyratis farinalis L., as a model species was crucial in implicating the C23 pentaene as an important component of the navel orangeworm pheromone blend. The four-component navel orangeworm pheromone blend was optimized using a combination of wind tunnel and field bioassays. Attractiveness of field deployed synthetic pheromone lures decreased rapidly despite incorporation of stabilizers and use of different release devices, suggesting that degradation products antagonize male navel orangeworm responses. Overall, the combination of type I lepidopteran pheromone components consisting of Cm aldehydes and alcohols with type H components consisting of long-chain polyunsaturated hydrocarbons has now been documented in several lepidopteran species and may indicate a paradigm shift in the range of compounds that constitute sex pheromone blends for individual lepidopteran species. This suggests that careful reexamination of pheromone gland contents for both type I and type II compounds may prove fruitful in species that have been studied but for which full attractant blends have eluded identification.

Boll weevils responded positively to eugenol on one of 12 trapping weeks when densities were high, but when densities were low (<2 weevils trap(-1) wk(-1)), there were no significant differences in captures for any dosage of eugenol offered in a standard boll weevil trap. Weekly grandlure volatilization did not differ by eugenol dose but was significantly different when evaluated over three different trapping periods and by week within trapping period due to differences in ambient temperature. The amount of grandlure that remained after 4 wk in moderate temperatures of spring was 13.1 +/- 0.19 mg (55.7% of original 25 mg of content) compared with 5.5 +/- 0.15 mg remaining (22.8% of original 25 mg content) after for 4 wk in summer heat. Weekly volatilization of grandlure for the summer trapping period was 9.8 +/- 0.32 mg for the first week, declining steadily to 1.0 +/- 0.09 mg by the fourth week of age. The data indicate that at high summer temperatures >30 degrees C, accumulative grandlure loss per week may be too high, leaving too little residual grandlure to effectively attract boll weevils at the end of 3 wk of trapping. Eugenol plays no role in reserving or encouraging the release of grandlure, or in increasing boll weevil captures when boll weevil densities are low.

Relatively little is known about the population movements of fall armyworm in the Caribbean and the magnitude of genetic interactions, if any, with populations from North, South, and Central America. To address this issue, a novel method involving mitochondrial haplotype ratios currently being used to study the migration of fall arm worm in North America was applied to populations in Puerto Rico. The results indicate limited interactions between Puerto Rico fall armyworm and those from Brazil or Texas but the potential for significant exchanges with populations in Florida.

Carriere, throughout the eastern United States. Systemic imidacloprid is one of the primary chemicals used to successfully control infestations of the hemlock woolly adelgid. The concentration levels for this systemic insecticide present in the sap of eastern hemlocks were evaluated from three strata within the canopy over a two year time span. Enzyme-linked immunosorbent assays were conducted every three months posttreatment to assess imidacloprid concentration within the sap. The effect of application timing (fall versus spring) and application method (soil drench, soil injection, and tree injection) on the translocation of imidacloprid throughout the canopy, and the quantity of imidacloprid translocated in the sap of eastern hemlock branches and the terminal twig and needle tissue was determined. Concentration levels progressively declined from the bottom strata to the top strata of the canopy. This trend was consistent in all chemically treated trees. Tree injections provided the lowest concentration and the most nonuniform distribution of imidacloprid throughout the canopy. The highest insecticide concentrations within the tree across all strata over the two year period were consistently associated with the soil drench method followed by the soil injection method. Imidacloprid concentrations peaked between month 9 and 12 posttreatment, and then declined; however, at two years posttreatment, soil drench and soil injected trees contained concentrations reported as being effective for control of the hemlock woolly adelgid.

L., in the Pacific Northwest of the United States. Spinosad bait is applied weekly to kill flies before they develop eggs, but its effects on oviposition by reproductively mature flies are unknown. In this study, the main objective was to identify insecticide bait treatments that can prevent oviposition after being ingested by reproductively mature R. indifferens. First, flies were fed liquid bait. Of flies fed spinosad bait, 20% oviposited and all died within 1 d. Of flies fed acetamiprid + sucrose, 72% oviposited after 1 wk, and all recovered from paralysis within 1 d. Of flies fed spinosad bait + acetamiprid, 7% oviposited and most died within 1 cl. None of the flies fed spinosad bait + thiamethoxam oviposited and all died within 1 cl. Of flies fed thiamethoxam + sucrose, 2% oviposited and most died within 1 d. None of the flies fed spinosad + thiamethoxam + sucrose oviposited and all died within 1 d. Of flies fed spinosad + sucrose, 11% oviposited and almost all died within 1 d. Next, flies were fed 2-d-old dried baits. No flies fed dried spinosad + thiamethoxam + sucrose and thiamethoxam + sucrose oviposited. On the basis of absolute numbers of eggs laid by flies fed liquid and dried treatments, spinosad + thiamethoxam + sucrose may be the most effective of the seven insecticide baits tested for preventing oviposition by reproductively mature R. indifferens.

TI Effect of Surround WP on Behavior and Mortality of Apple Maggot (Diptera: Tephritidae) SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE Surround WP; kaolin; particle film technology; apple maggot; behavior ID RHAGOLETIS-POMONELLA DIPTERA; PARTICLE FILMS; ARTHROPOD PESTS; FLY DIPTERA; FRUIT; FLIES; MANAGEMENT; KAOLIN; INSECTICIDES; PEAR AB Apple maggot, Rhagoletis pomonella (Walsh) (Diptera: Tephritidae), is a key pest in apple (Mains spp.) production areas located in the northeastern and midwestern United States and the eastern provinces of Canada. The development of Surround WP has offered a new approach for controlling apple maggot and other tephritid species, because this material is considered to be compatible with advanced integrated pest management and organic production systems. We conducted studies aimed at identifying the behavioral and biological effects of this material on apple maggots. Specifically, we examined the effect of Surround WP on the visual ecology of adult flies under field conditions, on tactile responses of flies in semifield trials, and on fly mortality in laboratory-based-bioassays. We demonstrated that an even coating of white particles over a fruit-mimicking sphere surface reduced visual attractiveness. We also found that spotty-coated fruit-mimicking spheres (meant to mimic ripe fruit bearing an uneven coating of Surround WP) were perceived by flies as not having the ideal round silhouette shape stimulus. Surround WP served as a tactile deterrent; the residence time of females introduced on to treated fruit was much shorter compared with untreated fruit. Surround WP also had a toxic effect on both adult apple maggot and Rhagoletis suavis (Loew); flies exposed to and forced to stand on Surround-treated surfaces died in <2 d in all trials. The combined effectiveness of Surround WP is based on a reduction in the attractiveness of fruit-based visual cues, an increase in the likelihood of flies leaving treated surfaces due to tactile deterrence, and a potential for increased mortality due to exposure to Surround WP particles.

TI Evaluation of Methyl Eugenol and Cue-Lure Traps With Solid Lure and Insecticide Dispensers for Fruit Fly Monitoring and Male Annihilation in the Hawaii Areawide Pest Management Program SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE tephritid flies; Bactrocera dorsalis; Bactrocera cucurbitae; naled; spinosad ID MELON FLIES DIPTERA; TEPHRITIDAE; SPINOSAD; ATTRACT; TRIALS AB Methyl eugenol (ME) and cue-lure (C-L) traps with solid lure dispensers were deployed in areas with low and high populations of oriental fruit fly, Bactrocera dorsalis (Hendel), and melon fly, Bactrocera cucurbitae (Coquillett), respectively. In low-density areas, standard Jackson traps or Hawaii Fruit Fly Areawide Pest Management (AWPM) traps with FT Mallet ME wafers impregnated with dimethyl dichloro-vinyl phosphate (DDVP) or AWPM traps with Scentry ME cones and vapor tape performed equally as well as standard Jackson traps with liquid ME/C-L and naled. Standard Jackson traps or AWPM traps with FT Mallet C-L wafers impregnated with DDVP or AWPM traps with Scentry C-L plugs with vapor tape performed equally as well as standard Jackson traps with a lure-naled solution. In high density areas, captures with traps containing FT Mallet wafers (ME and C-L) outperformed AWPM traps with Scentry cones and plugs (ME and C-L) with DDVP insecticidal strips over a 6-mo period. Captures of B. dorsalis and B. cucurbitae with wafers containing both ME and raspberry ketone (FT Mallet MC) were equivalent to those containing separate lures. From a worker safety and convenience standpoint, FT Mallet ME and C-L wafers with DDVP or Scentry plugs, with or without DDVP vapor tape, are more convenient and safer to handle than standard liquid insecticide formulations used for monitoring and male annihilation programs in Hawaii, and for detections traps used on the U.S. mainland. Furthermore, the FT Mallet MC wafer might be used in a single trap in place of two separate traps for detection of both ME and C-L responding fruit flies. C1 [Vargas, Roger I.; Mau, Ronald F.

TI Control of Overwintering Filbertworm (Lepidoptera: Tortricidae) Larvae With Steinernema carpocapsae SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE entomopathogenic nematodes; nematode efficacy; biological control; orchard floor cover; hazelnut ID CYDIA-POMONELLA LEPIDOPTERA; CODLING MOTH LEPIDOPTERA; ENTOMOPATHOGENIC NEMATODES; BIOLOGICAL-CONTROL; TEMPERATURE; PEST; SUSCEPTIBILITY; INFECTIVITY; RHABDITIDA; MANAGEMENT AB Filbertworm, Cydia latiferreana (Walsingham) (Lepidoptera: Tortricidae), is a key insect pest associated with hazelnuts, Corylus avellana L. (Fagales: Betulaceae), in North America. This study investigated the feasibility of entomopathogenic nematodes as an alternative strategy for filbertworm control. Laboratory and field experiments were conducted between October 2007 and May 2008 in Benton County, OR, to evaluate the ability of the nematode Steinernema carpocapsae (Weiser) (Rhabditida: Steinernematidae) to infect filbertworm larvae and pupae. The susceptibility of larvae with and without hibernacula as well as pupae to S. carpocapsae was tested in laboratory bioassays using nematode concentrations between 40 and 200 infective juveniles (IJs) per cm(2). Percentage of nematode infection was not significantly affected by the presence of hibernacula (infection range, 90-92%) compared with larvae without hibernacula (80-95%), or by pupal stage (50-75%) compared with larvae (65-75%). In additional field trials, the effect of nematode rate, water application rate, and orchard floor cover on nematode efficacy was determined in October 2007 and May/June 2008. Sentinel filbertworm larvae in plots with either bare soil or debris (leaves, twigs, husks, and blank nuts) were treated with S. carpocapsae at rates ranging from 40 to 150 Us per cm2 applied in 75 or 190 ml/m(2) water. Average filbertworm mortality ranged from 2 to 11% and from 50 to 78% in October and May, respectively. Larval mortality increased with increasing nematode concentration, but was not significantly affected by water application rate or orchard floor cover. Our experiments suggest that S. carpocapsae can play a role in the control of filbertworm larvae overwintering on the orchard floor.

Three combinations of application concentration and volume were used: double the recommended active ingredient concentration at one half the recommended volume (DR), the full concentration and volume (FR), and one half the concentration and twice the volume (HR). In all three cases, the same total amount of active ingredient (0.01 g of imidacloprid for Premise and 0.012 g of fipronil for Termidor) was applied to the same soil surface area (45.36 cm(2)). Regardless of soil or application method, the concentration of active ingredient was highest in the top 1 cm of soil. Within each soil, the concentration in the top 1 cm was highest in the DR treatment and lowest in the HR treatment. At each depth below 1 cm, active ingredient concentration was highest in the HR treatment and lowest in the DR treatment. The DR treatment therefore results in a thinner barrier of higher initial concentration in the top 1 cm, whereas the HR treatment results in a thicker barrier but of lower initial concentration in the top 1 cm.

TI A New Soybean Aphid (Hemiptera: Aphididae) Biotype Identified SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE soybean; soybean aphid; biotype; aphid; aphid resistance ID SINGLE DOMINANT GENE; RESISTANCE GENES; MOSAIC-VIRUS; GLYCINES; HOMOPTERA; TRANSMISSION; VARIABILITY; GERMPLASM; PI-243540; JACKSON AB Shortly after its arrival, the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), became established as the most important insect pest of soybean, Glycine max L. (Merr.), in the northern part of the North American soybean production region. Soybean resistance is an environmentally sustainable method to manage the pest and new soybean aphid resistant cultivars are beginning to be deployed into production. However, an earlier study identifying a soybean aphid biotype that could colonize plants with the Rag1 resistance gene has raised concerns about the durability of soybean aphid resistance genes. Choice and nonchoice tests conducted in this study characterized the colonization of a soybean aphid isolate, collected from the oyerwintering host Frangula alnus P. Mill in Springfield Fen, IN, on different aphid resistant soybean genotypes. This isolate readily colonized plants with the Rag2 resistance gene, distinguishing it from the two biotypes previously characterized and indicating that it represented a new biotype named biotype 3. The identification of soybean aphid biotypes that can overcome Rag1 and Rag2 resistance, even before soybean cultivars with the resistance genes have been deployed in production, suggests that there is high variability in virulence within soybean aphid populations present in North America. Such variability in virulence gives the pest a high potential to adapt to and reduce the effective life of resistance genes deployed in production. The search for new soybean aphid resistance genes must, therefore, continue, along with the development of alternative sustainable strategies to manage the pest.

Tests were done in a guava. Psidium guajava L., grove and involved releasing flies at a central point and recording the numbers captured after 7 h and I, 2, 3, and 6 d in an array of 25 Multilure traps located 9-46 m from the release point. In all tests, highest rate of recapture occurred within the first day of release, so estimations of sampling range were based on a 24-h period. Trap distances were grouped into four categories (<10, 10-20, 20-30, and >30 m from release point) and relative trapping efficiency (percentage of capture) was determined for each distance group. Effective sampling range was defined as the maximum distance at which relative trapping efficiency was >= 25%. This corresponded to the area in which 90% of the recaptures occured. Contour analysis was also performed to document spatial distribution of fly dispersal. In tests with sterile flies, immature females dispersed farther and were recovered in higher numbers than mature females, regardless of attractant, and recapture of both cohorts was higher with torula yeast. For mature feral flies, range of the synthetic lure was determined to be 30 m. With sterile females, effective range of both attractants was 20 m. Contour maps indicated that wind direction had a strong influence on the active space of attractants, as reflected by distribution of captured flies.

A 4.0-ha block of mature orange trees was stratified into 10 0.4-ha strata and sampled using each method seven times over a 7-mo period. One sticky trap was deployed per tree on each of 16 trees randomly selected in each stratum, and numbers of adults on the traps were counted 1 wk later. One stem-tap sample in which the number of adults falling into a pan after three rapid taps to a branch was taken per tree on each of 16 trees randomly selected in each stratum. A sampling protocol of one yellow sticky trap on each of 20 trees, or of one stem-tap sample on each of 30 trees, distributed uniformly across an area up to 4.0 ha (excluding block edges) was projected to provide an average sampling precision rate of <= 25% (SEM/mean x 100) at means of one or more adults per trap or stem-tap sample. Validation sampling indicated 20 sticky trap samples consistently provided the desired precision level at means of approximately two or more adults per trap but not at means of 1.0-1.5 per trap. A sample size of 30 stem-tap samples consistently provided the desired average precision level, but the precision of some individual estimates was >25% at means of around one adult per tap sample.

(Coleoptera: Tenebrionidae) was studied under 4 different diet regimes. Addition of dietary supplements consisting of dry potato or a mix of dry potato and dry egg whites significantly reduced the number of larval instars and total development time. The pattern of sequential stadia length showed regularity and low variability in instars 5 - 9. Stadia length continuously increased between instar 10 and the last instar before pupation (P(-1)). Instar number significantly impacted total development time and was also significantly correlated with stadia length. The length of the 1(st), 2(nd), 3(rd), and 4(th) stadia was not significantly affected by diet indicating that they may represent a stable part of the life cycle of T. molitor. The length of the last stadium (P(-1)) was regular within food treatments regardless of sequential instar number, but P(-1) was also significantly affected by nutrition in a similar way as all the sequential stadia. The pattern of instar variation is discussed in regard to the insertion of new instars based on variation of stadia length. C1 [Morales-Ramos, J. A.; Rojas, M. G.; Shapiro-Ilan, D. I.; Tedders, W.

Adult and larval Coccinellinae and Scymninae were sampled by beat-pan method and identified to species in a 3-year field study (1999 - 2001) conducted in northeast Arkansas. The coccinellids observed in descending order of abundance were Hippodamia convergens Guerin, Scymninae (Scymnus spp. and Diomus spp.), Coleome-gilla maculata (Degeer), Harmonia axyridis (Pallas), and Coccinella septempunctata L. Population dynamics and community structure by species for C. maculata, H. axyridis and C. septempunctata were unpredictable within and among years. Based on population densities, timing of colonization, and consistent delayed density-dependent relationship with aphid populations, H. convergens and Scymninae genera (Scymnus spp. and Diomus spp.) were the most important predators of cotton aphids in northeast Arkansas.

TI Actual and Simulated Injury of Creontiades signatus (Heteroptera: Miridae) Feeding on Cotton Bolls SO JOURNAL OF ENTOMOLOGICAL SCIENCE LA English DT Article DE Creontiades signatus; cotton; simulated; damage ID GREEN STINK BUG; PLANT BUGS; ABSCISSION; RESISTANCE; HEMIPTERA; PATTERNS AB The actual feeding injury of Creontiades signatus Distant (Heteroptera: Miridae) was compared with a simulated technique during 2005, 2006 and 2008 by injecting varying dilutions of pectinase into cotton bolls at different boll sizes (ages) and into 2 or 4 locules to determine if such a technique could be used to reduce the time and labor involved with conducting economic injury level studies in the field. The most accurate simulation occurred in 2008 by injecting 1 mu L of 10% pectinase into all 4 locules of a cotton boll. This improved the relationships of injury score to seed cotton, seed, and lint weights. The youngest boll age class of >= 2 cm diam. (2 d of age) was not significantly more damaged than the medium age >= 2.5 cm (8 d of age) bolls, and both sustained significantly more injury than the large boll classification of >= 3 cm (12 d of age). However, small bolls were at least 3 times more likely to abscise than medium-sized bolls, and large bolls did not abscise regardless of treatment. Some damage was observed for large bolls from the injected and actual feeding compared with the controls, but the lint and seed weights were not significantly different for any of the treatments including the controls. Our study characterizes the feeding injury caused by C. signatus and describes a simulated technique that may be used to further economic injury studies. C1 [Armstrong, J.

Tomato possesses two representatives of this lineage, TOMATO AGAMOUS (TAG1) and TOMATO AGAMOUS-LIKE1 (TAGL1), allowing for an analysis of diversification of function after gene duplication. Using RNAi (RNA interference) silencing, transgenic tomato lines that specifically down-regulate either TAGL1 or TAG1 transcript accumulation have been produced. TAGL1 RNAi lines show no defects in stamen or carpel identity, but show defects in fruit ripening. In contrast TAG1 RNAi lines show defects in stamen and carpel development. In addition TAG1 RNAi lines produce red ripe fruit, although they are defective in determinacy and produce ectopic internal fruit structures. e2814, an EMS- (ethyl methane sulphonate) induced mutation that is temperature sensitive and produces fruit phenotypes similar to that of TAG1 RNAi lines, was also characterized. Neither TAG1 nor TAGL1 expression is disrupted in the e2814 mutant, suggesting that the gene corresponding to the e2814 mutant represents a distinct locus that is likely to be functionally downstream of TAG1 and TAGL1. Based on these analyses, possible modes by which these gene duplicates have diversified in terms of their functions and regulatory roles are discussed.

There have been no previous reports on the genes encoding delta(6)-desaturase in blackcurrant (Ribes nigrum L.). In this research, five nearly identical copies of delta(6)-desaturase gene-like sequences, named RnD8A, RnD8B, RnD6C, RnD6D, and RnD6E, were isolated from blackcurrant. Heterologous expression in Saccharomyces cerevisiae and/or Arabidopsis thaliana confirmed that RnD6C/D/E were delta(6)-desaturases that could use both alpha-linolenic acids (ALA; C18:3 delta(9,12,15)) and linoleic acid (LA; C18:2 delta(9,12)) precursors in vivo, whereas RnD8A/B were delta(8)-sphlingolipid desaturases. Expression of GFP tagged with RnD6C/D/E showed that blackcurrant delta(6)-desaturases were located in the mitochondrion (MIT) in yeast and the endoplasmic reticulum (ER) in tobacco. GC-MS results showed that blackcurrant accumulated GLA and octadecatetraenoic acids (OTA; C18:4 delta(6,9,12,15)) mainly in seeds and a little in other organs and tissues. RT-PCR results showed that RnD6C and RnD6E were expressed in all the tissues at a low level, whereas RnD6D was expressed at a high level only in seeds, leading to the accumulation of GLA and OTA in seeds. This research provides new insights to our understanding of GLA synthesis and accumulation in plants and the evolutionary relationship of this class of desaturases, and new clues as to the amino acid determinants which define precise enzyme activity.

Average family weights were between 161 and 263 g with an average of 225 g at 213 days post-fertilization with specific growth rates ranging from 2.37 to 2.88. Per cent survival of fish challenged with F. psychrophilum was between 18% and 100%, while for those challenged with IHNV, the range was between 12% and 93%. Significant positive correlations were found for end body weight and resistance to IHN (P < 0.05) and for early body weight and resistance to BCWD (P < 0.1). However, no significant correlations were detected between resistance to both pathogens or disease resistance and overall genetic diversity or diversity within the major histocompatibility locus.

In this work, we measured the activities of acid phosphatase, alkaline phosphatase, phosphodiesterase, and non-buffered and buffered urease in soils under rainfed and irrigated potato with different crop rotation managements. Compared with continuous potato (Solanum tuberosum L.) production, three-year rotation practices increased all soil enzyme activities in rainfed condition by 10 to 86%. Irrigation increased alkaline phosphatase, phosphodiesterase, and both unbuffered and buffered urease activities, but decreased acid phosphatase activity compared with no irrigation. Under rainfed management, microbial biomass C level was highly correlated with phosphatase and urease activities. When measured under buffered conditions, urease activity was highly correlated with rainfed potato yield. To the extent that urease is an indicator of plant N availability, this may reflect the influence of N availability on yield. This study showed that both cropping system and water management influence the activities of several enzymes considered important for plant uptake of N and P. C1 [He, Zhongqi; Honeycutt, C.

The quantity of broken dehydrated precooked pinto beans in LSL fraction was four times more than in HSL fraction. The percentages of burst and split beans in LSL fraction were higher than in HSL fraction. Higher solid losses and hydration ratio were associated with low density.

The comparative risk of L. monocytogenes in retail-sliced versus prepackaged deli meats was evaluated with a modified version of this model. Other research has found that retail-sliced deli meats have both higher prevalence and levels of L. monocytogenes than have product sliced and packaged at the manufacturer level. The updated risk assessment model considered slicing location as well as the use of growth inhibitors. The per annum comparative risk ratio for the number of deaths from retail-sliced versus prepackaged deli meats was found to be 4.89, and the per-serving comparative risk ratio was 4.27. There was a significant interaction between the use of growth inhibitors and slicing location. Almost 70% of the estimated deaths occurred from retail-sliced product that did not possess a growth inhibitor. A sensitivity analysis, assessing the effect of the model's consumer storage time and shelf life assumptions, found that even if retail-sliced deli meats were stored for a quarter of the time prepackaged deli meats were stored, retail-sliced product is 1.7 times more likely to result in death from listeriosis. Sensitivity analysis also showed that the shelf life assumption had little effect on the comparative risk ratio.

TI Development of a Novel Immuno-PCR Assay for Detection of Ricin in Ground Beef, Liquid Chicken Egg, and Milk SO JOURNAL OF FOOD PROTECTION LA English DT Article ID FOOD MATRICES; PROTEIN; SAMPLES AB Reliable, sensitive, and high-throughput methods are essential for food defense, to detect foodborne contaminants and to facilitate remediation and recovery from potential toxin-related incidents. Ricin is a protein toxin that has been used for intentional contamination of foods in the past. In this study, we developed procedures for quantification of ricin in foods using immuno-PCR (IPCR). The direct adsorption of ricin onto the wells of a microtitration plate was compared with indirect immobilization via a capture antibody (sandwich IPCR). The latter procedure provided much greater sensitivity. We also compared a protocol with the immunoassay and PCR conducted in a single plate to a two-step procedure in which the PCR was conducted in a second plate, following release and transfer of the DNA marker. The two-step procedure proved 1,000-fold more sensitive for ricin detection, so this format was used to detect ricin in spiked samples of ground beef, chicken egg, and milk, and the results were compared with those obtained from enzyme-linked immunosorbent assay (ELISA). The IPCR had a limit of detection of 10 pg/ml in chicken egg and milk samples and 100 pg/ml in ground beef extracts. Comparable ELISA results were in the 1 to 10 ng/ml range. Thus, IPCR affords sensitivity that is 10-fold greater in the ground beef matrix, 100-fold greater in the milk, and 1,000-fold greater in the egg matrix than the sensitivity obtained by ELISA. Further optimization of the sandwich IPCR was performed by comparing various antibody combinations. Among the four formats investigated, the pAb-pAb combination yielded the lowest limit of detection (10 fg/ml).

AB Quality, nutritional and microbial analyses were completed for fresh-cut and frozen papaya cubes prepared from cultivars with varying resistance to internal yellowing (IY) disease caused by the bacterium Enterobacter cloacae. In general, fresh-cut and frozen papaya retained nutritional and microbial quality, but visual and textural quality declined. Fresh-cut fruit pretreated with 1% calcium lactate solution were firmer than control fruit, but translucency limited the shelf life of cubes dipped in either water or calcium lactate. Vitamin C content averaged 61.5 mg/100 g and 52.2 mg/100 g for fresh-cut and frozen fruit, respectively. Vitamin A content was greatest in fresh-cut "Laie. Gold" and "Rainbow",fruit, and averaged 35.1 mu g retinol activity equivalents per 100 g for all cultivars. Microbial counts were very low or not detectable for most samples. Among the cultivars resistant to IY, "Rainbow" had the highest vitamin A and sugar contents, and did not develop translucency. C1 [Wall, M. M.; Nishijima, K. A.; Fitch, M.

However, the tissue that remains after oil extraction does not have an established market. Discarded pink salmon (Oncorhynchus gorbuscha) tissues were preserved using a combination of smoke-processing and acidification with lactic acid bacteria (LAB). All samples were analyzed for moisture, protein, ash, and lipid contents. Bacterial cell counts, pH, and lactic acid concentrations were recorded as a measure of LAB viability. Neither raw nor smoked salmon were free from spoilage during 60 d of storage. Only fermented samples successfully stabilized below pH 4.7, while retaining lactic acid concentrations over 15 g/L during storage. When smoked, fermented salmon head tissues were dried, the pH of the resulting high-protein "cracker" was significantly lower than when crackers were prepared only from the smoked (but not fermented) salmon material. Both cracker varieties retained valuable polyunsaturated fatty acids. This research suggests that salmon-head tissues discarded after oil extraction represent a good source of protein and high-value fatty acids in a shelf-stable form. Practical Application: Alaska salmon oils are rich in n-3 polyunsaturated fatty acids and are highly valued by the food and pharmaceutical industries. However, the tissue that remains after oil extraction does not have an established market. Material produced from salmon tissue discarded after oil extraction may represent a valuable resource for preparing high-protein crackers and other fish-based food products. In addition to providing a unique smoke-flavoring, the smoked, fermented fish material may also impart antioxidant factors thereby extending the shelf life of the product.

A major reduction in waste salt could be achieved if NaCl were eliminated from the cucumber fermentation process. The objectives of this project were to ferment cucumbers in brine containing CaCl(2) as the only salt, to determine the course of fermentation metabolism in the absence of NaCl, and to compare firmness retention of cucumbers fermented in CaCl(2) brine during subsequent storage compared to cucumbers fermented in brines containing both NaCl and CaCl(2) at concentrations typically used in commercial fermentations. The major metabolite changes during fermentation without NaCl were conversion of sugars in the fresh cucumbers primarily to lactic acid which caused pH to decrease to less than 3.5. This is the same pattern that occurs when cucumbers are fermented with NaCl as the major brining salt. Lactic acid concentration and pH were stable during storage and there was no detectable production of propionic acid or butyric acid that would indicate growth of spoilage bacteria. Firmness retention in cucumbers fermented with 100 to 300 mM CaCl(2) during storage at a high temperature (45 degrees C) was not significantly different from that obtained in fermented cucumbers with 1.03 M NaCl and 40 mM CaCl(2). In closed jars, cucumber fermentations with and without NaCl in the fermentation brine were similar both in the chemical changes caused by the fermentative microorganisms and in the retention of firmness in the fermented cucumbers.

The concentration of total phenolic compounds of commercial baby juices ranged from 176.7 to 347.7 mg/mL. Commercial baby juices showed poor antimicrobial activity, reducing less than 1-log of C. sakazakii in juice samples for 2 h at 37 degrees C. Red muscadine juices, regardless of processing methods (filtration, pasteurization, and sterilization), achieved a 6-log reduction of C. sakazakii in the same time period (2 h). The mixture of synthetic organic acids (malic and tartaric acids) and polyphenolic acid (tannic acid) showed strong antimicrobial activity against C. sakazakii. Among synthetic organic acids, tannic acid was undetected in commercial baby juices. Tannic acid showed the highest antimicrobial activity (1.4-to 3.8-log reduction) against C. sakazakii, while malic and tartaric acids showed less than 0.5-log reduction. These results suggest that red muscadine juice could be utilized as a natural antimicrobial in baby food formulations to inhibit C. sakazakii. C1 [Kim, T. J.; Weng, W. L.; Silva, J.

In particular, land managers are becoming increasingly burdened with societal problems as a result of encroaching development and increased forest use. This article reports on a process used by the Ocala National Forest, Florida, to work through societal issues common in many US forests. Specifically, this article describes (1) the Ocala National Forest situation, (2) the workshop that drove the process, and (3) progress made after the workshop. Identified solutions required the development of long-term, collaborative strategies; however, the process showed that immediate and successful techniques can be identified and implemented when agency personnel use nontraditional decisionmaking strategies. Strengths of the process proved to be the ability to improve communication across administrative layers, engage new and existing partners in a process focused on solutions, and develop immediate solutions, which are designed to result in long-term improvements.

After the first identification of chicoric acid in Ocimum basilicum (basil), the extent to which chicoric acid could be found within the family Lamiaceae was investigated. The dominant phenolic acid in all Lamiaceae samples was rosmarinic acid, which ranged from 2.04 mg/100 g (one of 12 oregano samples) to 622.28 mg/100 g (lemon balm). Of the herbs tested in this study (marjoram, oregano, peppermint, rosemary, sage, spearmint, and thyme from the family Lamiaceae), only basil and lemon balm (Melissa officinalis) contained chicoric acid. Basil samples (starting material and resulting end product) obtained from an industry cooperator, showed substantial phenolic deficiency as a result of processing (approximately 78% loss).

The Autographa californica multicapsid nucleopolyhedrovirus P74 protein is an ODV envelope protein that is essential for ODVs to be infectious. P74 is anchored in the ODV envelope by a C-terminal transmembrane anchor domain and is N-terminally exposed on the ODV surface. In the present study, a series of N-terminal and C-terminal truncation mutants of P74 were evaluated for their ability to rescue per os infectivity of the P74-null virus, AcLP4. It was discovered that a P74 truncation mutant lacking the C-terminal transmembrane anchor domain of P74 was able to rescue per os infection. This result shows that a soluble form of P74 retains per os infectivity factor function and suggests that P74 may be complexed with other proteins in the ODV envelope.

In addition to its crucial role in virus replication, recent studies have indicated its involvement in modulating host immunity. In this study, each of the six identified immunodominant nsp2 B-cell epitopes (ES2-ES7) was deleted using a type I PRRSV cDNA infectious clone. Deletion of ES3, ES4 or ES7 allowed the generation of viable virus. In comparison with the parental virus, the Delta ES3 mutant showed increased cytolytic activity and more vigorous growth kinetics, whilst the Delta ES4 and Delta ES7 mutants displayed decreased cytolytic activity and slower growth kinetics in MARC-145 cells. These nsp2 mutants were characterized further in a nursery pig disease model. The results showed that the Delta ES4 and Delta ES7 mutants exhibited attenuated phenotypes, whereas the Delta ES3 mutant produced a higher peak viral load in pigs. The antibody response reached similar levels, as measured by IDEXX ELISA at 21 days post-infection, and slightly higher levels of mean virus neutralizing titres were observed from pigs infected by the Delta ES4 and Delta ES7 mutants. The expression of innate and T-helper 1 cytokines was measured in peripheral blood mononuclear cells or virus-infected macrophages. The results consistently showed that interleukin-1 beta and tumour necrosis factor alpha expression levels were downregulated in cells that were stimulated (or infected) with the Delta ES3 mutant compared with parental virus and the other nsp2 deletion mutants. These results suggest that certain regions in nsp2 are non-essential for PRRSV replication but may play an important role in modulation of host immunity in vivo.

Although the impact of WGO on insect physiology is important, the mechanisms of these actions are poorly understood. In this paper, we test the hypothesis that the addition of WGO to medium developed for larval oriental fruit flies modulates gene expression in the corresponding adults. We separately reared larvae of Bactrocera dorsalis on diets lacking or supplemented with WGO, and analyzed for expressed proteins in the resulting adult males and females by 2D-electrophoresis. Analysis of the gels revealed significant changes in expression levels of >70 proteins, 64 of which were identified by mass spectrometric analysis on MALDI-TOF/TOF. Apparent changes in expression levels for 6 of these proteins were confirmed by quantitative real-time PCR, showing that the changes in mRNA expression were reflected in changes in protein expression. These findings support the hypothesis that one mechanism of WGO actions in insect nutrition is the modulation of gene expression. (C) 2010 Published by Elsevier Ltd.

Quantitative (or real-time) PCR was used to amplify food-specific DNA and measure consumption rates and digestion efficiencies of four foods - two prey (Aphis glycines and Leptinotarsa decemlineata eggs) and two non-prey (Zea mays pollen and the yeast Saccharomyces cerevisiae) species over different larval stages of Coleomegilla maculata. The amount of Z. mays pollen consumed increased as larvae aged, but not proportionately with larval size, such that consumption rates decreased uniformly with insect age. While aging larvae fed A. glycines had a similar pattern in their diminishing consumption rates, they consumed similar amounts of A. glycines regardless of age, suggesting a negative feedback mechanism for consumption of this species of aphids. Older larvae digested three of the four foods significantly more efficiently than younger larvae, the exception being larvae fed A. glycines which was digested at a similar rate throughout the larval stage. There was a significant effect of time on food quantity detected for all four species of food. We conclude that C. maculata expands its physiological capacity for digesting prey and non-prey foods as they age in order to better accommodate the increased nutritional needs of the older larvae. This strategy has important implications for the life history strategies of zoophytophagous insects and how they function within foods webs. Published by Elsevier Ltd.

Techniques to estimate ET have been available for many years, while more recently remote sensing data have extended ET into a spatially distributed context. However, remote sensing data cannot be easily used in decision systems if they are not available frequently. For many crops ET estimates are needed at intervals of a week or less, but unfortunately due to cost, weather, and sensor availability constraints, high resolution (< 100 m) remote sensing data are usually available no more frequently than 2 weeks. Since resolution of this problem is unlikely to occur soon, a modeling approach has been developed to extrapolate remotely sensed inputs needed to estimate ET. The approach accomplishes this by combining time-series observations from ground-based radiometers and meteorological instruments with episodic visible, near infrared, and thermal infrared remote sensing image data. The key components of the model are a vegetation density predictor and a diurnal land surface temperature disaggregator, both of which supply needed inputs to a surface energy balance model. To illustrate model implementation, remote sensing and ground-based experimental data were collected for cotton grown in 2003 at Maricopa, Ariz. Spatially distributed cotton canopy densities were forecasted for a 22-day interval using vegetation indices from remote sensing and fractional cover from ground-level photography. Spatially distributed canopy and soil surface temperatures were predicted at 15-min time steps for the same interval by scaling diurnal canopy temperatures according to time of day and vegetative cover. Considering that the predictions span a rapid growth phase of the cotton crop, comparison of spatially projected canopy cover with observed cover were reasonably good, with R-2=0.65 and a root-mean-squared error (RMSE) of 0.13. Comparison of predicted temperatures also showed fair agreement with RMSE=2.1 degrees C. These results show that combining episodic remotely sensed data with continuous ground-based radiometric data are a technically feasible way to forecast spatially distributed input data needed for ET modeling over crops.

Modeling reveals that the commonly held assumption of the hardness strain rate sensitivity (m(H)) equaling the flow stress strain rate sensitivity (m(sigma)) is violated except in low hardness/modulus materials. Another commonly held assumption is that for self-similar indenters the indent area increases in proportion to the (depth)(2) during creep. This assumption is also violated. Both violations are readily explained by noting that the proportionality "constants" relating (i) hardness to flow stress and (ii) area to (depth)(2) are, in reality, functions of hardness/modulus ratio, which changes during creep. Experiments on silicon, fused silica, bulk metallic glass, and poly methyl methacrylate verify the breakdown of the area-(depth)(2) relation, consistent with the theory. A method is provided for estimating area from depth during creep. C1 [Stone, Don S.] Univ Wisconsin, Dept Mat Sci & Engn, Madison, WI 53706 USA.

TI Mechanical properties and area retention of leather dried with biaxial stretching under vacuum SO JOURNAL OF MATERIALS SCIENCE LA English DT Article ID ACOUSTIC-EMISSION; RESISTANCE; ENERGY AB The conversion of animal hides to leather involves many complicated chemical and mechanical operations. Drying is one of the mechanical operations, and plays a key role in determining the physical properties of leather. It is where leather acquires its final texture, consistency, and flexibility. We have investigated a drying method using a combination of vacuum and biaxial stretching. Total area loss often accompanies drying of leather; however, by adding a stretching action during vacuum drying one may significantly increase the area retention and dimensional stability. Moreover, this method is particularly advantageous to heat-vulnerable organic tanned leathers because vacuum drying offers fast moisture removal at a low temperature. We investigated this dual functional drying method and observed how drying variables affected the mechanical properties and area retention of chrome-free leather. We used a central composite experimental design to formulate the relationship between drying variables and resultant leather properties into second-order polynomial equations. Results showed that the stretching applied in a drying operation significantly affects mechanical properties, area retention, and thickness of leather. Moreover, studies showed that biaxial stretching increased the tensile strength but had less effect on fracture energy. A significant area increase of 16% can be achieved by using this combined drying (vacuum plus stretching) method compared to the regular vacuum dried leather without stretching.

The procedure involves two PCR steps using the species-specific outer and inner primer pairs. Different annealing temperatures allow both the first and the second rounds of PCR to be performed sequentially in the same closed tube. The first PCR with outer primers was performed at a higher annealing temperature and with limited amount of primers to prevent interference with the inner primers during the second round of PCR. The specificity of the dual primer TaqMan(R) is high because the fluorescent signal can only be generated from the TaqMan(R) probes that are homologous to the product amplified by the outer and inner primers. This new detection system can reliably detect as few as single copies of target DNA. The sensitivity of the dual primer system is comparable to the conventional two-tube nested PCR, but it eliminates the potential risk of cross contamination commonly associated with conventional nested PCR. This one-tube dual primer TaqMan(R) PCR method is gel-free with reduced handling time and is cost effective. At the same time, this system provides significantly increased sensitivity, improved reliability and high through-put capability suitable for routine, large scale diagnoses of clinical plant tissue and insect samples. The technique described here is generic and can be applied to the detection of other plant pathogenic bacteria. Published by Elsevier B.V.

We developed a multi-staining immunofluorescent method to detect vitamin D receptor expression and co-localize it with myosin heavy chain isoform expression in skeletal muscle biopsies in older female subjects. Serial sections were cut from frozen samples obtained by needle biopsy of the vastus lateralis. Samples were probed with a primary vitamin D receptor monoclonal antibody and then re-probed with a type IIa myosin heavy chain isoform-specific antibody. Independent unfixed sections followed a similar protocol and were probed with type IIx and type I myosin heavy chain isoform-specific antibodies. Immunohistochemistry and fluorescent microscopy co-localized vitamin D receptor loci and myosin heavy chain isoforms in whole skeletal muscle sections. We quantified intranuclear vitamin D receptor staining patterns and number of individual muscle fiber subtypes within a muscle section. Immunohistochemical staining of the vitamin D receptor was confirmed by Western blot using the same monoclonal antibody. This multi-staining immunofluorescent technique allows for measurement of intranuclear vitamin D receptor expression in the context of the specific muscle fiber type profile in a single section. This method can thus be a useful approach to study potential relationships between muscle fiber subtypes and vitamin D receptor expression.

Samples were removed for the determination of Warner Bratzler shear force (WBSF), centrifugal moisture loss (CML), gravitational drip loss (DL), color, protein solubility and sodium dodecyl sulfate polyacryamide gel electrophoresis (SDS-PAGE) analysis of whole muscle protein extracts. WBSF decreased with HDP (P < 0.05) and aging treatments (P < 0.0001). CML decreased (P < 0.0001) with aging. Controls exhibited slightly less DL after 1 day than HDP samples, but the increase in DL between 1 and 7 days was similar for control and HDP samples. Treatment effects on L*, a* and b* measurements were minimal. Myofibrillar and total protein solubility were higher (P < 0.01) in HDP samples compared with controls at day 0 but not at day 7. Sarcoplasmic protein solubility decreased (P < 0.05) with aging. SDS-PAGE analysis of muscle proteins demonstrated a strong aging effect and only minor HDP differences. With aging, bands corresponding to 30-33 and 135 kDa increased (P < 0.0001), while bands corresponding to 38 and 95 kDa decreased (P < 0.05) in intensity (relative to the actin band). The 60 kDa band intensity increased (P < 0.05) with both aging and HDP treatments. Thus, data from this study suggest that HDP enhances aging tenderization in pork loins through the physical disruption of the muscle ultrastructure while having little detrimental effect on other parameters of pork quality.

Similar estimates were calculated for vitamin D intake from food and dietary supplements using NHANES 2005-2006. Diet was assessed with 2 24-h recalls; dietary supplement and antacid use were determined by questionnaire. The National Cancer Institute method was used to estimate usual nutrient intake from dietary sources. The mean daily nutrient intake from supplemental sources was added to the adjusted dietary intake estimates to produce total usual nutrient intakes for calcium and vitamin D. A total of 53% of the U.S. population reported using any dietary supplement (2003-2006), 43% used calcium (2003-2006), and 37% used vitamin D (2005-2006). For users, dietary supplements provided the adequate intake (AI) recommendation for calcium intake for similar to 12% of those 71 y. Males and females aged 1-3 y had the highest prevalence of meeting the AI from dietary and total calcium intakes. For total vitamin D intake, males and females >= 71, and females 14-18 y had the lowest prevalence of meeting the AI. Dietary supplement use is associated with higher prevalence of groups meeting the AI for calcium and vitamin D. Monitoring usual total nutrient intake is necessary to adequately characterize and evaluate the population's nutritional status and adherence to recommendations for nutrient intake. J.

TI Dietary zinc reduces osteoclast resorption activities and increases markers of osteoblast differentiation, matrix maturation, and mineralization in the long bones of growing rats SO JOURNAL OF NUTRITIONAL BIOCHEMISTRY LA English DT Article DE Zinc; Bone; Extracellular matrix; Resorption; Rats ID CARBONIC-ANHYDRASE-II; RESISTANT ACID-PHOSPHATASE; GROWTH-PLATE; ALKALINE-PHOSPHATASE; PARATHYROID-HORMONE; CALCIUM-METABOLISM; GENE-EXPRESSION; DEFICIENT RATS; IV COLLAGENASE; TRACE MINERALS AB The nutritional influence of zinc on markers of bone extracellular matrix resorption and mineralization was investigated in growing rats. Thirty male weanling rats were randomly assigned to consume AlN-93G based diets containing 2.5, 5, 7.5,15 or 30 mu g Zn/g diet for 24 days. Femur zinc increased substantially as zinc increased from 5 to 15 mu g/g diet and modestly between 15 and 30 mu g/g (P<.05). By morphological assessment, trabecular bone increased steadily as dietary zinc increased to 30 mu g/g. Increasing dietary zinc tended to decrease Zip2 expression nonsignificantly and elevated the relative expression of metallothionen-I at 15 but not 30 mu g Zn/g diet. Femur osteoclastic resorption potential, indicated by matrix metalloproteinases (MMP-2 and MMP-9) and carbonic anhydrase-2 activities decreased with increasing dietary zinc. In contrast to indicators of extracellular matrix resorption, femur tartrate-resistant acid and alkaline phosphatase activities increased fourfold as dietary zinc increased from 2.5 to 30 mu g Zn/g. Likewise, 15 or 30 mu g Zn/g diet resulted in maximum relative expression of osteocalcin, without influencing expression of core-binding factor alpha-1, collagen Type 1 alpha-1, or nuclear factor of activated T cells cl. In conclusion, increased trabecular bone with additional zinc suggests that previous requirement estimates of 15 mu g Zn/g diet may not meet nutritional needs for optimal bone development. Overall, the up-regulation of extracellular matrix modeling indexes and concomitant decrease in resorption activities as dietary zinc increased from 2.5 to 30 mu g/g provide evidence of one or more physiological roles for zinc in modulating the balance between bone formation and resorption.

NOV; RUMINANTS; ARTIODACTYLA; BIOGEOGRAPHY; SYSTEMATICS; GENERA; FAUNA AB The independence of Pseudomarshallagia and its placement among the medium stomach worms of ungulates, Ostertagiinae, is confirmed based on comparative morphological studies of the synlophe and genital attributes among male and female specimens. An emended description of Pseudomarshallagia elongata is presented based on a series of specimens in sheep from northern Ethiopia. Pseudomarshallagia elongata is retained among the 15 genera of the Ostertagiinae based on presence of a prominent esophageal-intestinal valve, paired "0" papillae, a modified accessory bursal membrane containing the paired "7" papillae, and configuration of the copulatory bursa. The structure of the synlophe in males and females is also typical and within the range of variation demonstrated for Type II and Type A cervical patterns among other ostertagiines. We emphasize the importance of continued survey and inventory of parasite faunas to establish the limits of diversity on local, regional, and global scales. Consequently we strongly encourage routine deposition of voucher specimens from all survey activities designed to explore faunal diversity. Although this is particularly important in regions that remain poorly known, such as Africa, the principle certainly applies more broadly.

The mode of action of DFMs involves multiple mechanisms, including direct inhibition of enteric pathogens and indirectly through competitive exclusion of pathogens by the normal gut microbiota. Additionally, recent basic research efforts have focused on the effects of DFMs on promoting host immunity and on the complex interactions between the gut microflora and immune system development. This review will summarize the latest developments in DFM studies with particular emphasis on the underlying mechanisms of immune enhancement.

The data were solely obtained by direct mass spectrometric profiling, including tandem fragmentation, of selected tissues from single specimens, which yielded a largely complete accounting of the putative bioactive neuropeptides; truncated neuropeptides with low abundance were not counted as mature peptides. Differential processing within the CNS was detected for the CAPA-precursor, and differential post-translational processing (pyroglutamate formation) was detected for AST-C and CAPA-PVK-2. For the first time in insects, we succeeded in the direct mass spectrometric profiling of midgut tissue which yielded a comprehensive and immediate overview of the peptides involved in the endocrine system of the gut. Head peptides which were earlier identified as the most abundant RFamides of Ae. aegypti, were not detected in any part of the CNS or midgut. This study provides a framework for future investigations on mosquito endocrinology and neurobiology. Given the high sequence similarity of neuropeptide precursors identified in other medically important mosquitoes, conclusions regarding the peptidome of Ae. aegypti likely are applicable to these mosquitoes.

TI Evaluation of Odors Associated with Land Application of Biosolids SO JOURNAL OF RESIDUALS SCIENCE & TECHNOLOGY LA English DT Article AB An odor study was performed at a biosolids application demonstration site using several different gas collection devices and analytical methods to determine changes in air concentration of several organic and inorganic compounds associated with biosolids application over various time periods. Various organic and inorganic odorants were detected at 1 5 m above the ground surface within the biosolids application zone area immediately after application They then decreased to non-detectable levels within 196 h after application, consistent with other biosolids application studies. Air samples collected from flux chambers installed within the application zone contained detectable concentrations of various organic odorants immediately after biosolids application. The concentrations of these odorants may have been influenced by the increased temperature within the flux chambers, and the change in concentration of these odorants over time was affected by the various sample analysis method. Airborne concentrations of ammonia and hydrogen sulfide rapidly decreased within 4 h after biosolids application, and they further decreased to non-detectable levels within 196 h after application. The highest measurements for both ammonia and hydrogen sulfide did not approach any health criterion or guidance levels for these compounds.

Village lands tend to be managed at very fine spatial scales (a parts per thousand currency sign30 m), with managers altering soil fertility and even terrain by terracing, irrigation, fertilizing, and other land use practices. Under these conditions, accumulation of excess phosphorous in soils has become important contributor to eutrophication of surface waters across China's densely populated village landscapes. The aim of this study was to investigate relationships between fine-scale patterns of agricultural management and soil total phosphorus (STP) within China's village landscapes. First, China's village landscapes were divided into five environmentally distinct regions across China. Within each region, a single 100 km(2) research site was then selected, and 12 500 x 500 m square landscape sample cells were selected for fine-scale mapping. Soils were sampled within fine-scale landscape features using a regionally weighted landscape sampling design. STP stock across the 0.9 x 10(6) km(2) area of our five village regions was approximately 0.14 Pg (1 Pg = 10(15) g), with STP densities ranging from 0.08 kg m(-2) in Tropical Hilly Region to 0.22 kg m(-2) in North China Plain and Yangtze Plain, with village landscape STP density varying significantly with precipitation and temperature. Outside the Tropical Hilly Region, STP densities also varied significantly with land form, use, and cover. As expected, the highest STP densities were found in agricultural lands and in areas near buildings, while the lowest were in nonproductive lands and forestry lands. As a combined result of these high STP densities and the predominance of agricultural land use, most village STP stock was found in agricultural lands. A surprisingly large portion of village STP stock was associated with built structures and disturbed lands surrounding them (15.0% in North China Plain, 19.3% in Yangtze Plain, 5.9% in Sichuan Hilly Region, 7.8% in Subtropical Hilly Region, 2.7% in Tropical Hilly Region), which had a significant relationship with population density. Our results demonstrated that local patterns of land management and human residence were associated with substantial differences in STP both within and across China's village landscapes which have increased their potential contribution to P pollution. With the rapid change in land use/land cover in China's densely populated landscapes, such information is essential for rational planning of future management to reach agricultural sustainability.

However, little is known about the susceptibility of eggs of P. interpunctella to aerosol insecticides applied in active field sites. We conducted several trials by exposing eggs of P. interpunctella to synergized pyrethrins, alone and in combination with the insect growth regulator methoprene. Eggs in diets and packaging materials containing the food products were directly exposed to the aerosols. There was significant variation among the food products, as assessed by adult emergence from exposed eggs, but in general there was no difference in adult emergence from eggs exposed to a 1% versus a 3% pyrethrin formulation when methoprene was included. There was no difference in efficacy between diets and diet packages placed in open areas versus areas that were in some way obstructed to the aerosol. Adult emergence was generally reduced in the treatment combinations compared to untreated controls. A partial budget analysis indicated that the combination treatment of 1% pyrethrins methoprene represented the lowest risk, lowest cost, and would seem to be the optimum combination. Results show that field applications of aerosols could be used to control P. interpunctella in storage facilities. Published by Elsevier Ltd. C1 [Arthur, F.

TI Alcoholic Beverage Consumption, Nutrient Intakes, and Diet Quality in the US Adult Population, 1999-2006 SO JOURNAL OF THE AMERICAN DIETETIC ASSOCIATION LA English DT Article ID NUTRITION EXAMINATION SURVEY; HEALTHY EATING INDEX-2005; NATIONAL-HEALTH; ITALIAN WOMEN; SMOKING; HABITS; FOOD; MEN; EDUCATION; CANCER AB Background Little is known about associations between alcoholic beverage consumption, nutrient intakes, and diet quality, although each has been independently associated with chronic disease outcomes. Objective This study examines cross-sectional relationships between alcoholic beverage consumption, nutrient intakes, and diet quality (Healthy Eating Index-2005 [HEI-2005] scores) in the US adult population. Methods Data were from four cycles of the National Health and Nutrition Examination Survey (1999-2006). Weighted multiple regression analyses, adjusted for age, race/ethnicity, education, smoking status, and body mass index included 8,155 men and 7,715 women aged >= 20 years who reported their past-year alcoholic beverage consumption and 24-hour dietary intake. Alcoholic beverage consumption was defined by drinking status (never, former, current drinker) and, among current drinkers, by drinking level (number of drinks per day, on average: men <1 to >= 5; women <1 to >= 3). Results Among men, there was no association between drinking status and intakes of energy, most nutrients, or total HEI-2005 score. Among women, former and current (compared to never) drinkers had significantly higher intakes of energy and several nutrients, and current drinkers had significantly lower total HEI-2005 scores (current drinkers 58.9; never drinkers 63.2). Among current drinkers of both sexes, as drinking level increased, intakes of energy and several nutrients significantly increased, whereas total HEI-2005 scores significantly decreased (from 55.9 to 41.5 in men, and from 59.5 to 51.8 in women). Conclusions Among men and women, increasing alcoholic beverage consumption was associated with a decline in total diet quality as measured by the HEI-2005, apparently due to higher energy intake from alcohol as well as other differences in food choices. Educational messages should focus on nutrition and chronic disease risk associated with high consumption of alcoholic beverages and poor food choices, including excessive energy intake.

Lee, Joseph TI ACOUSTIC EMISSION STUDIES FOR LEATHER USING DUAL SENSORS SO JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION LA English DT Article ID POLY(LACTIC ACID); FIBER ORIENTATION; COMPOSITES; CALFSKIN AB Since leather is sold by the square foot, destructive tests lessen the square footage of the material and infringe on the leather manufacturer's total profit. Therefore there is a need for developing an instrument to perform nondestructive testing of the physical properties of leather. In this investigation, experiments were designed to pass leather test samples through a pair of rotational acoustic sensors, thereby enabling the collection of acoustic emission (AE) signals from both the grain and corium and provide a more accurate assessment of the quality of leather. Observations showed a strong correlation between the mechanical properties of leather and the corresponding cumulative acoustic energy. We also used this dynamic method to characterize the grain break of leather. Results showed that the difference in grain break could be determined from the amount of acoustic hits collected from moving the AE sensors over a leather sample. Observations showed the poorer the grain break; the more AE energy was detected. Data also demonstrated that thicker samples tended to have poorer grain break. In short, this study demonstrated that the tensile strength, stiffness, toughness and grain break could be nondestructively determined by measuring acoustic quantities with a pair of rotational sensors.

TI POWDERED HIDE FOR RESEARCH ON TANNING MECHANISMS SO JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION LA English DT Article ID THERMAL-STABILITY; COLLAGEN; LEATHER; SKIN AB The conversion of animal hides into leather, the most valuable coproduct of the US meat industry, is a multistep process that has evolved more as art form than as science. A variety of dehairing and other hide preparation processes have been adopted without an understanding of how they affect the chemical and physical properties of the resulting leather. To develop a basis for designing or selecting effective sustainable tanning agents, a suitable model system must include an evaluation of the effects of pretanning steps. A protocol for the production of powdered hide is described. Moisture, ash, total protein as collagen, hydrothermal stability, collagenase resistance, proteoglycan content and molecular weight distribution were compared for powdered hide prepared from bated and not-bated hide. This research provides a basis for assessing the effects of different process steps, and represents an initial step in the development of well-characterized model systems for comparing research from different laboratories on tanning mechanisms.

TI Ring-Opening Polymerization of Epoxidized Soybean Oil SO JOURNAL OF THE AMERICAN OIL CHEMISTS SOCIETY LA English DT Article DE Epoxidized soybean oil; Boron trifluoride diethyl etherate; Methylene chloride; Ring-opening polymerization ID POLYOLS; ADHESIVES; POLYMERS AB Ring-opening polymerization of epoxidized soybean oil (ESO) catalyzed by boron trifluoride diethyl etherate (BF(3)center dot OEt(2)) in methylene chloride was conducted in an effort to develop useful biodegradable polymers. The resulting polymerized ESO (PESO) were characterized using infrared (IR) spectroscopy, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), (1)H NMR, (13)C NMR, solid state (13)C NMR and gel permeation chromatography (GPC). The results indicated that PESO materials were highly crosslinked polymers. They had glass transition temperatures ranging from -16 to -48 A degrees C. TGA results showed the PESO polymers were thermally stable at temperatures up to 220 A degrees C. Decomposition of the polymers was found to occur at temperature greater than 340 A degrees C. GPC results indicated the extracted soluble substances from PESO polymers were ESO dimers, trimers and polymers with low molecular weights. The resulting crosslinked polymers can be converted into hydrogels by chemical modification, such as hydrolysis. These soy based hydrogels will find applications in personal care and health care areas. C1 [Liu, Zengshe; Erhan, Sevim Z.] ARS, NCAUR, USDA, Peoria, IL 61604 USA.

The most common method used for BD production is based on the alkali-catalyzed transesterification of first-use refined oils and fats with an alcohol (e.g. methanol). These technologies, however, require significant modification when applied to second use materials such as greases because of their higher free fatty acid (FFA) content. Recently, we reported a series of insoluble porous polymer grafted diphenylammonium salts that efficiently esterified the FFA in greases to FAME. In this work, the diphenylammonium salts were supported onto two robust mesoporous silicas. The resulting catalysts had high esterification activity with > 99% of the FFA in greases converted to FAME, and the FFA content in the treated greases was reduced to < 1 wt%. The mesoporous silica-supported catalysts displayed minimal transesterification activity. C1 [Ngo, Helen L.; Foglia, Thomas A.] ARS, USDA, Eastern Reg Res Ctr, Wyndmoor, PA 19038 USA.

TI Bur and Nut Production on Three Chestnut Cultivars SO JOURNAL OF THE AMERICAN POMOLOGICAL SOCIETY LA English DT Article AB Studies were conducted to characterize bur and nut development on shoots of young chestnut (Castanea sp.) trees over a two year period and to determine the effect of secondary (2 degrees) bur removal on subsequent bur and nut production. Terminal shoots of 'Peach' trees with primary (1 degrees) and 2 degrees burs (PS) grew longer and had greater stem diameter than those shoots with 1 degrees burs only (PO), 2 degrees burs only (SO), or with no burs (VO). PS shoots of 'Peach' had greater 1 degrees nut weight per shoot than the other types of shoots in 2006. PS shoots also produced 2 degrees nuts with as much or more weight per shoot than SO shoots. For 'Peach' trees, 2005 fruiting or vegetative shoots were most likely to develop a VO shoot in 2006. PS shoots of 'Willamette' trees typically produced more 1 degrees nut weight per shoot than the other types of shoots. However, 2 degrees nut weights per shoot were similar for PS and SO shoots on 'Willamette' trees. The odds of 2005 fruiting or vegetative 'Willamette' shoots developing into PO shoots the following year were >= 50%. When 2 degrees burs were removed from shoots of 'Orrin' trees in late July (R treatment), 1 degrees nut weight per shoot at harvest and the number of 1 degrees bur-bearing shoots in the following year were greater than that on shoots where 2 degrees burs were not removed (N treatment). Thus, 1 degrees nut weights were enhanced by 2 degrees bur removal, as well as subsequent 1 degrees bur production. For 'Willamette' trees, R-treated trees also had relatively more 1 degrees nut weight per shoot than N-treated shoots at harvest in the year the treatment was imposed, but most 1 degrees flowers were killed by an early April freeze event the following year. In spite of this loss, a marketable crop of 2 degrees nuts was produced. C1 [Warmund, Michele R.; Enderton, Darin J.] Univ Missouri, Div Plant Sci, Columbia, MO 65211 USA. [Van Sambeek, J.

Our emphasis is on the role that riparian vegetation plays in protecting streams from nonpoint source pollutants and in improving the quality of degraded stream water. Riparian vegetation influences stream water chemistry through diverse processes including direct chemical uptake and indirect influences such as by supply of organic matter to soils and channels, modification of water movement, and stabilization of soil. Some processes are more strongly expressed under certain site conditions, such as denitrification where groundwater is shallow, and by certain kinds of vegetation, such as channel stabilization by large wood and nutrient uptake by faster-growing species. Whether stream chemistry can be managed effectively through deliberate selection and management of vegetation type, however, remains uncertain because few studies have been conducted on broad suites of processes that may include compensating or reinforcing interactions. Scant research has focused directly on the response of stream water chemistry to the loss of riparian vegetation or its restoration. Our analysis suggests that the level and time frame of a response to restoration depends strongly on the degree and time frame of vegetation loss. Legacy effects of past vegetation can continue to influence water quality for many years or decades and control the potential level and timing of water quality improvement after vegetation is restored. Through the collective action of many processes, vegetation exerts substantial influence over the well-documented effect that riparian zones have on stream water quality. However, the degree to which stream water quality can be managed through the management of riparian vegetation remains to be clarified. An understanding of the underlying processes is important for effectively using vegetation condition as an indicator of water quality protection and for accurately gauging prospects for water quality improvement through restoration of permanent vegetation.

These heterogeneous processes have recently been conceptualized as "hot spots and moments" of retention, degradation, or production. Nevertheless, studies investigating the importance of hot phenomena (spots and moments) in riparian zones have thus far largely focused on nitrogen (N) despite compelling evidence that a variety of elements, chemicals, and particulate contaminant cycles are subject to the influence of both biogeochemical and transport hot spots and moments. In addition to N, this review summarizes current knowledge for phosphorus, organic matter, pesticides, and mercury across riparian zones, identifies variables controlling the occurrence and magnitude of hot phenomena in riparian zones for these contaminants, and discusses the implications for riparian zone management of recognizing the importance of hot phenomena in annual solute budgets at the watershed scale. Examples are presented to show that biogeochemical process-driven hot spots and moments occur along the stream/riparian zone/upland interface for a wide variety of constituents. A basic understanding of the possible co-occurrence of hot spots and moments for a variety of contaminants in riparian systems will increase our understanding of the influence of riparian zones on water quality and guide management strategies to enhance nutrient or pollutant removal at the landscape scale.

We conducted this comparison at the 1 km2, 9 km2, and gauged watershed scales within the Baltimore Ecosystem Study to determine the usefulness and limitations of the NLCD in heterogeneous urban to exurban environments for the determination of land-cover information for hydrological applications. Although the NLCD canopy and impervious data are significantly correlated with the high-resolution land-cover dataset, both layers exhibit bias at < 10 and > 70% cover. The ratio of total impervious area and connected impervious area differs along the range of percent imperviousness - at low percent imperviousness, the NLCD is a better predictor of pavement alone, whereas at higher percent imperviousness, buildings and pavement together more resemble NLCD impervious estimates. The land-cover composition and range for each NLCD urban land category (developed open space, low-intensity, medium-intensity, and high-intensity developed) is more variable in areas of low-intensity development. Fine-vegetation land-cover/lawn area is incorporated in a large number of land use categories with no ability to extract this land cover from the NLCD. These findings reveal that the NLCD may yield important biases in urban, suburban, and exurban hydrologic analyses where land cover is characterized by fine-scale spatial heterogeneity.

TI Utilisation of corn (Zea mays) bran and corn fiber in the production of food components SO JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE LA English DT Review DE maize; co-products; corn fiber gum; vanillin; ferulic acid; xylo-oligosaccharides ID WATER-UNEXTRACTABLE ARABINOXYLANS; LOWERS PLASMA-CHOLESTEROL; CELL-WALL POLYSACCHARIDES; FERULIC ACID; DIETARY FIBER; MAIZE BRAN; WHEAT BRAN; FERULOYLATED OLIGOSACCHARIDES; ASPERGILLUS-NIGER; BREAD-MAKING AB The milling of corn for the production of food constituents results in a number of low-value co-products. Two of the major co-products produced by this operation are corn bran and corn fiber, which currently have low commercial value. This review focuses on current and prospective research surrounding the utilization of corn fiber and corn bran in the production of potentially higher-value food components. Corn bran and corn fiber contain potentially useful components that may be harvested through physical, chemical or enzymatic means for the production of food ingredients or additives, including corn fiber oil, corn fiber gum, cellulosic fiber gels, xylo-oligosaccharides and ferulic acid. Components of corn bran and corn fiber may also be converted to food chemicals such as vanillin and xylitol. Commercialization of processes for the isolation or production of food products from corn bran or corn fiber has been met with numerous technical challenges, therefore further research that improves the production of these components from corn bran or corn fiber is needed.

The presence of Cd in agricultural soils is of great concern regarding its entry into the food chain. Cadmium enters into the soil-plant environment mainly through anthropogenic activities. Compounds of Cd are more soluble than other heavy metals, so it is more available and readily taken up by plants and accumulates in different edible plant parts through which it enters the food chain. A number of approaches are being used to minimize the entry of Cd into the food chain. Proper plant nutrition is one of the good strategies to alleviate the damaging effects of Cd on plants and to avoid its entry into the food chain. Plant nutrients play a very important role in developing plant tolerance to Cd toxicity and thus, low Cd accumulation in different plant parts. In this report, the role of some macronutrients (nitrogen, phosphorus, sulfur and calcium), micronutrients (zinc, iron and manganese), and silicon (a beneficial nutrient) has been discussed in detail as to how these nutrients play their role in decreasing Cd uptake and accumulation in crop plants.

Effects of steam treatment on bending properties and chemical composition of moso bamboo (Phyllostachys pubescens). Effects of temperature (25, 160 and 200 degrees C) and time (15 and 30 min) of steam treatment on the mechanical and chemical characteristics of most) bamboo were studied. The modulus of rupture (MOR) and modulus of elasticity (MOE) of the outer culm were at least 2.4 and 2.2 times respectively greater than those of the inner culm. Temperature and time had no effect on bending properties oldie outer and inner cubits. A significant decrease it) MOR occurred after the specimens were subjected to 200 degrees C. The per cent MOR reduction after 30 nun treatment at 200 degrees C was more than 33 and 29% respectively, as compared with that or 25 and 160 degrees C, but steam treatment had no effect on MOE. Of the three major chemical constituents of baniboo, alpha-cellulose was very stable to temperature and tune, but lignin content increased slightly when temperature was increased to 200 degrees C. However, the hemicellulose content decreased substantially as temperature increased. The similar decreases for hemicellulose content and MOR of bamboo suggested that hemicelltdose loss in thermallydegraded bamboo was correlated with MOR strength loss. At 200 degrees C, there were significant decreases iii MOR, hemicellulose content and pH, and increases in hot water extractives, ethanol benzene extractives, 1% NaOH extractives and lignin content.

Location Southwestern Oregon, USA. Methods In severely burned plantations, dynamics of (1) shrub, herbaceous, and cryptogam richness; (2) cover; (3) topographic, overstory, and site influences were characterized on two contrasting aspects 2 to 4 years following fire. Analysis of variance was used to examine change in structural layer richness and cover over time. Non-metric multidimensional scaling, multi-response permutation procedure, and indicator species analysis were used to evaluate changes in community composition over time. Results Vegetation established rapidly following wildfire in burned plantations, following an initial floristics model of succession among structural layers. Succession within structural layers followed a combination of initial and relay floristic models. Succession occurred simultaneously within and among structural layers following wildfire, but at different rates and with different drivers. Stochastic (fire severity and site history) and deterministic (species life history traits, topography, and pre-disturbance plant community) factors determined starting points of succession. Multiple successional trajectories were evident in early succession. Conclusions Mixed conifer forests are resilient to interacting effects of natural and human-caused disturbances. Predicting the development of vegetation communities following disturbances requires an understanding of the various successional components, such as succession among and within structural layers, and the fire regime. Succession among and within structural layers can follow different successional models and trajectories, occurs at different rates, and is affected by multiple interacting factors.

The utility of the assay was demonstrated with both Chinese hamster ovary (CHO) and bovine pulmonary artery endothelial (CPAE) cells. Since heparin sulfate (HS) has been shown to function as a receptor for a number of viruses, its role as a receptor for BTV was evaluated with the in situ IFA. Binding of BTV to both CHO and CPAE cells was inhibited in a dose dependent manner by HS. In addition, HS deficient CHO cells showed greatly diminished binding of BTV when compared to the parental cell line. The IFA protocol will find application, as a non-isotopic, quantifiable technique, to study virus-cell receptor interactions. Information gained from such studies will expand our understanding of the early steps in virus replication. Published by Elsevier B.V.

We conducted a 3-yr survey (2004-2006) of fleas from Gunnison's prairie dogs (Cynomys gunnisoni) and their burrows in montane grasslands in Valles Caldera National Preserve in New Mexico. Our objectives were to describe flea communities and identify flea and rodent species important to the maintenance of plague. We live-trapped prairie dogs and conducted burrow sweeps at three colonies in spring and summer of each year. One hundred thirty prairie dogs and 51 golden-mantled ground squirrels (Spermophilus let-myths) were captured over 3,640 trap nights and 320 burrows were swabbed for fleas. Five flea species were identified from prairie clogs and ground squirrels and four were identified from burrow samples. Oropsylla hirsute was the most abundant species found on prairie clogs and in burrows. Oropsylla idahoensis was most common on ground squirrels. Two colonies experienced plague epizootics in fall 2004. Plague-positive fleas were recovered from burrows (O. hirsuta and Oropsylla tuberculate tuberculate) and a prairie clog (O. hirsuta) in spring 2005 and summer 2006. Three prairie dogs collected in summer 2005 and 2006 had plague antibody. We found a significant surge in flea abundance and prevalence, particularly within burrows, following plague exposure. We noted an increased tendency for flea exchange opportunities in the spring before O. hirsute reached its peak population. We hypothesize that the role of burrows as a site of flea exchange, particularly between prairie clogs and ground squirrels, may be as important as summer conditions that lead to buildup in O. hirsute populations for determining plague outbreaks.

Since then, significant efforts have been directed toward reducing deer densities in the area in the hopes of reducing the bovine TB prevalence rate in deer and eliminating spillover of the disease into cattle. Despite the success of the efforts to reduce deer densities, additional cattle herds have become infected. Other mammals can be infected with M. bovis, and some carnivores and omnivores had been found to be infected with the disease in northern Michigan, USA. We conducted a multiyear surveillance effort to detect bovine TB in wild species of mammals in the Michigan, USA, outbreak area. From 2002 to 2004, tissue samples from 1,031 individual animals of 32 species were collected, processed, and cultured for M. bovis. Only 10 (1.0%) were culture-positive for M. bovis (five raccoons [Procyon lotor], four opossums [Didelphis. virginiana], and one grey fox [Urocyon cinereoargenteus]). We also found two raccoons and four opossums to be positive for Mycobacterium avium. We collected 503 environmental samples from cattle farms recently identified as bovine TB positive; none yielded positive M. bovis culture results. Finally, we used infrared cameras to document wildlife use of four barns in the area. Many avian and mammalian species of wildlife were observed, with raccoons being the most commonly observed species. Tins surveillance study identified no new wildlife species that should be considered significant reservoirs of bovine TB in the outbreak area in northern Michigan, USA. However, the relatively high, apparent bovine TB prevalence rates in sonic carnivorous and omnivorous species, their relatively long life spans, and their frequent use of barns, suggests that removal of raccoons, opossums, foxes, and coyotes (Canis lotions) should be considered when a newly infected farm is depopulated of cattle.

TI AVIAN PARAMYXOVIRUSES IN SHOREBIRDS AND GULLS SO JOURNAL OF WILDLIFE DISEASES LA English DT Article DE Avian paramyxovirus; Delaware Bay; Red Knot; Ruddy Turnstone; shorebird ID RED KNOTS; DELAWARE BAY; INFLUENZA; WATERFOWL AB There are nine serotypes of avian paramyxovirus (APMV), including APMV-1, or Newcastle disease virus. Although free-flying ducks and geese have been extensively monitored for APMV, limited information is available for species in the order Charadriiformes. From 2000 to 2005 we tested cloacal swabs from 9,128 shorebirds and gulls (33 species, five families) captured in 10 states within the USA and in three countries in the Caribbean and Smith America. Avian paramyxoviruses were isolated from 60 (0.7%) samples by inoculation of embryonating chicken eggs; isolates only included APMV-1 and APMV-2. Two isolates (APMV-2) were made from gulls and 58 isolates (APMV-1 [4] isolates] and APMV-2 [17 isolates) were made from shorebirds. All of the positive shorebirds were sampled at Delaware Bay (Delaware and New jersey) and 45 (78%) of these isolates came from Ruddy Turnstones (Arenaria interpres). The APMV-1 infection rate was higher among Ruddy Turnstones compared with other shorebird species and varied by year. Avian paramyxovirus-2 was isolated from two of 394 (0.5%) Ruddy Turnstones at Delaware Bay in 2001. and from 13 of 735 (1.8%) Ruddy Turnstones during 2002. For both APMV-1 and APMV-2, infection rates were higher among Ruddy Turnstones sampled on the south shore of Delaware Bay compared to north shore populations. This spatial variation may be related to local movements of Ruddy Turnstones within this ecosystem. The higher prevalence of APMV in Ruddy Turnstones mirrors results observed for avian influenza viruses in shorebirds and may suggest similar modes of transmission.

Removal of deer social units (localized management) has been proposed as a strategy to alleviate deer overbrowsing in forest systems. We conducted an experimental localized removal in a high-density deer population in the central Appalachians of West Virginia, USA, during winter 2002. We removed 51 deer within a 1.1-km(2) area that encompassed 2 forest regeneration sites (14 ha). During the summer following removal, we detected decreases in distance from the removal area in 8 of 30 (26.7%) adult females having pretreatment mean telemetry locations <2.5 km from the center of the removal area. We measured browsing rates during the summers of 2001-2004 from forest regeneration sites to examine efficacy of localized management. Browsing rates declined annually in both removal and control areas, due in part to increased timber harvesting on the larger study site, suggesting that increasing forage availability may be more effective at reducing impacts on forest regeneration than localized reductions in deer populations. Three years after the initial removal, we removed an additional 31 deer from the original 1.1-km(2) removal area. Home range shifts of adjacent deer coupled with the large number of animals collected in the second removal suggests that localized management only produces temporary voids within high-density deer herds. Localized management may not effectively reduce negative impacts of deer in areas of high deer density. C1 [Miller, Brad F.] Arkansas Game & Fish Commiss, Little Rock, AR 72205 USA.

Whether habitat suitability actually relates to demographics, however, has rarely been evaluated. We validated HSI models of breeding habitat suitability for wood thrush (Hylocichla mustelina) and yellow-breasted chat (Icteria virens) in Missouri, USA. First, we evaluated HSI models as a predictor of 3 demographic responses: within-site territory density, site-level territory density, and nest success. We demonstrated a link between HSI values and all 3 types of demographic responses for the yellow-breasted chat and site-level territory density for the wood thrush. Second, we evaluated support for models containing HSI values, models containing measured habitat features (e. g., tree age, tree species, ecological land type), and models containing management treatments (e. g., even-aged and uneven-aged forest regeneration treatments) for each demographic response using model selection. Models containing HSI values received more support, in general, than models containing only habitat features or management treatments for all 3 types of wildlife response. The assumption that changes in habitat suitability represent wildlife demographic response to vegetation change is supported by our models. However, differences in species ecology may contribute to the degree to which HSI values are related to specific demographic responses. We recommend validation of HSI models with the particular demographic data of interest (i.e., density, productivity) to increase confidence in the model used for conservation planning.

We quantified the effects of 4 canopy tree-retention treatments on amphibian oviposition patterns in clusters of 60-L aquatic mesocosms located in each treatment. We also related aquatic and terrestrial biophysical parameters in treatment plots to oviposition patterns. Cope's gray treefrogs (Hyla chrysoscelis) deposited more egg masses in clear-cut and 25-50% tree-retention treatments than in controls. In contrast, mountain chorus frogs (Pseudacris brachyphona) deposited more egg masses in unharvested control and 75% retention treatments than in clear-cut or 25-50% retention treatments. Spotted salamanders (Ambystoma maculatum) only deposited eggs in 75% retention treatments and controls. The number of egg masses deposited by mountain chorus frogs was positively related to canopy cover and negatively related to water temperature, pH, and dissolved oxygen, whereas we noted the opposite relationships for Cope's gray treefrogs. We did not detect a relationship between the number of egg masses deposited by any species and the distance of mesocosms to either the nearest mature closed-canopy forest or to the nearest natural amphibian breeding pool. The impacts of the silvicultural treatments we studied were species-specific and depended on the amount of trees removed. In areas where protection of spotted salamander and mountain chorus frog breeding habitat is a priority, we recommend harvests retain at least 75% of the canopy. Our results also suggest that retention of 25-50% of canopy trees surrounding amphibian breeding pools has little conservation benefit.

We compared the stress response to a novel environmental situation and repeated handling between bighorn sheep born and raised in captivity (CR) and bighorn sheep born in the wild (WC) and brought into captivity. We measured plasma epinephrine, norepinephrine, cortisol, and fecal glucocorticoid metabolites (FGM). Three weeks after each group's arrival we used a one-time drop-net event to elicit an acute stress response, and we collected blood samples from each sheep over 35 minutes, as well as one fecal sample. We collected blood and fecal samples from both groups on 7 other occasions over the subsequent 6 months. We also collected fecal samples from the pen at approximately 24-hour intervals for 3 days following every handling event to monitor the stress response to handling. We found that CR sheep had a stronger autonomic nervous system response than WC sheep, as measured by epinephrine and norepinephrine levels, but we found a very similar hypothalamic-pituitary-adrenal axis (HPA) response, measured by cortisol levels, to the acute stress event of a drop-net restraint. We also found that once the WC sheep had acclimated, as indicated by the return to the initial baseline FGM levels within 12 weeks, the CR and WC groups' HPA responses to sampling events were not significantly different from one another. Fecal samples can provide a noninvasive mechanism for managers to monitor baseline FGM for a given herd. Using long-term monitoring of FGM rather than values from a single point in time may allow managers to correlate these levels to outside influences on the herd and better understand the impacts of management changes, population density, or increased human developments on the health of the sheep population.

We characterized vegetation structure of 3 semiarid plant communities to compare cover pole measurements, standard measurements of vegetation cover, composition, height, and the proportion of the soil surface exposed by large intercanopy gaps. We propose that a more versatile and interpretable description of wildlife habitat can be generated using a line-point intercept method together with measurements of vegetation height and the proportion of the soil surface exposed by large intercanopy gaps.

Because woodpeckers inflicted essentially no damage to the fully coated crossarms, we infer that the coating material holds substantial promise for protecting utility pole crossarms.

Object-based image analysis, segmenting images into homogeneous regions called objects, has been suggested for increasing accuracy of remotely-sensed products, but little research has gone into determining image object size with regard to scaling of ecosystem properties. We looked at how segmentation of high-resolution Ikonos and medium-resolution Landsat images into successively coarser objects affected multivariate correlations between image data and eight percent-cover measurements of a sagebrush ecosystem. We also looked at changes in correlation as imagery was aggregated into larger square pixels. We found similar canonical correlations between field and image data at the finest scales, but higher for image segmentation than pixel aggregation for both images when scale increased. For image segmentation, correlations between the canonical variables and original field variables were invariant with respect to size of the image objects, suggesting linear scaling of vegetation cover in our study system. We detected a scaling threshold with the Ikonos segmentation and confirmed with a semi-variogram of the sample data. Below the threshold interpretation of the canonical variables was consistent: scale levels differed primarily in the amount of detail portrayed. Above the threshold, meaning of the canonical variables changed. This approach proved useful for evaluating overall utility of images to address an objective, and identified scaling limits for analysis. Selection of appropriate scale for analysis will ultimately depend on the objective being considered. C1 [Karl, Jason W.] Idaho Chapter Nat Conservancy, Hailey, ID 83333 USA.

Brahman bulls were selected based on temperament score (average of exit velocity, EV, and pen score, PS) measured 28 days prior to weaning with the 8 most Calm (0.89 +/- 0.15 EV and 1.00 +/- 0.00 PS), 8 most Temperamental (3.70 +/- 0.29 EV and 4.88 +/- 0.13 PS), and the 8 Intermediate (1.59 +/- 0.12 EV and 2.25 +/- 0.16 PS) selected from a pool of 60 bulls. Whole blood was collected pre- and post-transport, and rectal temperature recording devices were inserted pre-transport for continual collection of rectal temperature during transport. Bulls were transported in a trailer 770 km from Overton, TX (32.27 N, -94.98 W, 153 m altitude) to New Deal, TX (33.74 N, -101.84 W, 1006 m altitude). Serum cortisol and plasma epinephrine concentrations were determined. Prior to transportation (0 min) Temperamental bulls had greater rectal temperature than Calm or Intermediate bulls (P < 0.05). Rectal temperature peaked within 30 min after the onset of transportation with Temperamental bulls having greater peak rectal temperatures than Calm or Intermediate bulls (P < 0.05). The lowest mean rectal temperature was reached 400 min after the onset of transportation with Calm bulls having lower mean rectal temperatures than Intermediate or Temperamental bulls (P < 0.05). Prior to transportation Temperamental bulls had greater cortisol concentrations than Calm bulls (P < 0.05). Temperamental bulls had greater concentrations of epinephrine prior to transportation than Calm or Intermediate bulls (P < 0.05). Temperamental bulls also had greater concentrations of cortisol and epinephrine post-transportation than Calm bulls (P < 0.05). Maximum and minimum rectal temperature were positively correlated (r = 0.73; P < 0.01). There was a positive correlation between EV and maximum rectal temperature (r = 0.62; P = 0.01), and a trend for EV to be positively correlated with minimum rectal temperature (r = 0.43; P = 0.10). Epinephrine tended to be positively correlated with maximum rectal temperature (r = 0.46; P = 0.06). Both cortisol (pre-transportation r = 0.55; P = 0.02) and epinephrine (pre- and post-transportation (r = 0.64; P < 0.01 and r = 0.59; P < 0.01, respectively) were positively correlated with EV. In summary, temperament was predictive of 1) changes in rectal temperature due to transportation and 2) circulating concentrations of cortisol and epinephrine before and after transportation.

TI Effects of cooked temperature on pork tenderness and relationships among muscle physiology and pork quality traits in loins from Landrace and Berkshire swine SO MEAT SCIENCE LA English DT Article DE Pigs; Pork quality; Temperature; Tenderness ID INTRAMUSCULAR FAT-CONTENT; EATING QUALITY; MEAT QUALITY; GROWTH-RATE; END-POINT; SELECTION; COOKING; PIGS; CLASSIFICATION; CHOPS AB The effect of, and associations between, loin muscle morphology and pork quality indicator traits were assessed at three cooked temperatures in loin chops from 38 purebred Berkshire and 52 purebred Landrace swine. Three loin chops from each pig were randomly assigned to cooked temperature treatments of 62, 71, or 79 degrees C and loin tenderness was assessed as Warner-Bratzler shear force (WBSF). Cooked temperature (P < 0.001), breed (P < 0.001) and breed x cooked temperature (P < 0.001) effects influenced loin chop WBSF, whereby WBSF increased as cooked temperature increased. Chops from Landrace pigs had greater WBSF at each cooked temperature compared with chops from Berkshire pigs. Chops from Landrace pigs became less tender with increasing cooked temperature, whereas chops from Berkshire pigs became less tender only when cooked to 79 degrees C. In loins from Landrace pigs, Minolta a* at 62 degrees C (R(2) = 0.07), and average muscle fiber diameter at 71 degrees C and 79 degrees C (R(2) = 0.07 and 0.24, respectively), contributed to WBSF variation. In contrast, for loins from Berkshire pigs, loin ultimate pH and intramuscular fat percentage accounted for 27% and 30% of the variation in WBSF at 62 degrees C and 71 degrees C, respectively, and loin ultimate pH accounted for 7% of variation in WBSF at 79 degrees C. Results suggest that loins from Berkshire pigs have properties that resist toughening at greater cooked temperatures and that associations between quality measures and loin tenderness differ between Landrace and Berkshire pigs.

TI Molecular Ecology Of Macrolide-Lincosamide-Streptogramin B Methylases in Waste Lagoons and Subsurface Waters Associated with Swine Production SO MICROBIAL ECOLOGY LA English DT Article ID TETRACYCLINE RESISTANCE GENES; TIME PCR ASSAYS; ANTIBIOTIC-RESISTANCE; PRODUCTION FACILITIES; CONFERRING RESISTANCE; TYLOSIN; SEQUENCE; QUANTIFICATION; CAMPYLOBACTER; DETERMINANTS AB RNA methylase genes are common antibiotic resistance determinants for multiple drugs of the macrolide, lincosamide, and streptogramin B (MLS(B)) families. We used molecular methods to investigate the diversity, distribution, and abundance of MLS(B) methylases in waste lagoons and groundwater wells at two swine farms with a history of tylosin (a macrolide antibiotic structurally related to erythromycin) and tetracycline usage. Phylogenetic analysis guided primer design for quantification of MLS(B) resistance genes found in tylosin-producing Streptomyces (tlr(B), tlr(D)) and commensal/pathogenic bacteria (erm(A), erm(B), erm(C), erm(F), erm(G), erm(Q)). The near absence of tlr genes at these sites suggested a lack of native antibiotic-producing organisms. The gene combination erm(ABCF) was found in all lagoon samples analyzed. These four genes were also detected with high frequency in wells previously found to be contaminated by lagoon leakage. A weak correlation was found between the distribution of erm genes and previously reported patterns of tetracycline resistance determinants, suggesting that dissemination of these genes into the environment is not necessarily linked. Considerations of gene origins in history (i.e., phylogeny) and gene distributions in the landscape provide a useful "molecular ecology" framework for studying environmental spread of antibiotic resistance.

The segregation in the F(4:5) population indicates that the resistance was conditioned by a single dominant gene designated B (12.) Simple sequence repeat (SSR) markers identified as putatively linked to the resistance gene by bulked segregant analysis were confirmed on the entire F(4:5) population. Three SSR markers, CIR246, BNL3545 and BNL3644 on chromosome 14, were found closely linked to B (12) . The association between CIR246 and B (12) was validated among 354 plants of 16 diverse varieties. Based on Monsanto SSR/single nucleotide polymorphism (SNP) consensus map, SNP markers closely linked to CIR246 were used to screen 'DeltaOpal' and 'DP388' for polymorphism. The polymorphic SNP markers were run on the F(4:5) population and the four SNP markers spanning 3.4 cM were found to flank the resistance gene on chromosome 14. The linkage between B (12) and the 4-SNP marker haplotype was validated using 18 elite cotton lines. This 4-SNP marker haplotype can be used for marker assisted selection for bacterial blight resistance breeding programs or for screening germplasm collections for this locus rapidly.

Such selection is particularly likely to act on traits expressed early in development since early survival is necessary for the expression of adaptive phenotypes later in life. Genetic studies of fitness under field conditions, however, seldom include the earliest developmental stages. Using a new set of recombinant inbred lines, we present a study of the genetic basis of fitness variation in Arabidopsis thaliana in which genotypes, environments, and geographic location were manipulated to study total lifetime fitness, beginning with the seed stage. Large-effect quantitative trait loci (QTLs) for fitness changed allele frequency and closely approached 90% in some treatments within a single generation. These QTLs colocated with QTLs for germination phenology when seeds were dispersed following a schedule of a typical winter annual, and they were detected in two geographic locations at different latitudes. Epistatically interacting loci affected both fitness and germination in many cases. QTLs for field germination phenology colocated with known QTLs for primary dormancy induction as assessed in laboratory tests, including the candidate genes DOG1 and DOG6. Therefore fitness, germination phenology, and primary dormancy are genetically associated at the level of specific chromosomal regions and candidate loci. Genes associated with the ability to arrest development at early life stages and assess environmental conditions are thereby likely targets of intense natural selection early in the colonization process.

Plant genetic and solar UV-B radiation effects on the diversity of the phyllosphere were examined by measuring epiphytic bacterial ribosomal DNA diversity in a maize recombinant inbred (RI) mapping population. Several chromosomal quantitative trait loci (QTL) with significant effects on bacterial diversity, were identified, some of which had effects only in the presence of UV-B radiation and others that had effects both with and without UV-B. Candidate genes with allele-specific effects were snapped to the bacterial diversity chromosomal regions. A glutamate decarboxylase candidate gene was located at a UV-B-specific chromosomal locus, and in a comparison between two RI lines with contrasting bacterial diversity phenotypes, high bacterial diversity was associated with high levels of glutamate decarboxylase enzyme activity, a component of the gamma-aminobutyric acid (GABA) pathway. The bacterial diversity loci exhibited a significant overlap with loci connected with Southern leaf blight (SLB) susceptibility in the field. A SLB-resistant inbred genotype had less beta bacterial diversity, and antibiotic treatment of inbreds increased this diversity. These results suggest that the GABA pathway is genetically associated with phyllosphere bacterial diversity. Furthermore, the colocalization of QTL between low bacterial diversity and fungal blight-resistance and the increase in beta diversity in antibiotic-treated leaves suggest that occupation of leaf habitats by a particular set of suppressive bacteria may restrict phyllosphere bacterial variability and increase resistance to fungal infection.

Mycotoxin, fumonisins produced by this pathogen pose a threat to human and animal health. Because CAMP signaling has been implicated in regulating diverse developmental and infection processes in fungal pathogens, in this study, we aimed to elucidate the function of the CAMP-protein kinase A (PKA) pathway in toxin production and plant infection in h: verticillioides. Targeted deletion mutants were generated for the CPK1 and FAC1 genes that encode a catalytic subunit of PKA and the adenylate cyclase, respectively. Defects in radial growth and macroconidiation were observed in both the cpk1 and fac1 deletion mutants. The fact mutant also was significantly reduced in virulence and microconidiation but increased in tolerance to heat and oxidative stresses. These phenotypes were not observed in the cpk1 mutant, indicating that additional catalytic subunit of PKA must exist and function downstream from FAC1. The fact mutant formed microconidia mainly in false heads. The expression levels of the hydrophobia genes HYD1 and HYD2, which are known to be associated with change in formation of microconidia, were significantly reduced in the fact mutant. Expression of F. verticillioides GSY2 and HSP26 genes, two other putative downstream targets of FAC1, was increased in the fac1 mutant and may be associated with its enhanced stress tolerance. Although fumonisin production was normal, biosynthesis of bikaverin was increased in the fact mutant, suggesting that FACT and cAMP signaling may have pathway- or metabolite-specific regulatory roles in secondary metabolism. Overall, the pleiotropic defects of the fact deletion mutant indicate that the cAMP-PKA pathway is involved in growth, conidiation, bikaverin production, and plant infection in F. verticillioides.

Experimental evidence from association and linkage populations in maize (Zea mays L.) demonstrate that the gene encoding beta-carotene hydroxylase 1 (crtRB1) underlies a principal quantitative trait locus associated with beta-carotene concentration and conversion in maize kernels. crtRB1 alleles associated with reduced transcript expression correlate with higher beta-carotene concentrations. Genetic variation at crtRB1 also affects hydroxylation efficiency among encoded allozymes, as observed by resultant carotenoid profiles in recombinant expression assays. The most favorable crtRB1 alleles, rare in frequency and unique to temperate germplasm, are being introgressed via inexpensive PCR marker-assisted selection into tropical maize germplasm adapted to developing countries, where it is most needed for human health.

TI Mixed linear model approach adapted for genome-wide association studies SO NATURE GENETICS LA English DT Article ID QUANTITATIVE TRAIT LOCI; SIRE EVALUATION; POPULATION-STRUCTURE; BREEDING PROGRAM; COMPLEX TRAITS; HIP-DYSPLASIA; SELECTION; PEDIGREE; SAMPLES; POWER AB Mixed linear model (MLM) methods have proven useful in controlling for population structure and relatedness within genome-wide association studies. However, MLM-based methods can be computationally challenging for large datasets. We report a compression approach, called 'compressed MLM', that decreases the effective sample size of such datasets by clustering individuals into groups. We also present a complementary approach, 'population parameters previously determined' (P3D), that eliminates the need to re-compute variance components. We applied these two methods both independently and combined in selected genetic association datasets from human, dog and maize. The joint implementation of these two methods markedly reduced computing time and either maintained or improved statistical power. We used simulations to demonstrate the usefulness in controlling for substructure in genetic association datasets for a range of species and genetic architectures. We have made these methods available within an implementation of the software program TASSEL.

TI Effect of Channel Catfish Stocking Rate on Yield and Water Quality in an Intensive, Mixed Suspended-Growth Production System SO NORTH AMERICAN JOURNAL OF AQUACULTURE LA English DT Article ID SHRIMP LITOPENAEUS-VANNAMEI; AQUACULTURE SYSTEMS; EARTHEN PONDS; TILAPIA; NUTRIENT; NITROGEN; CULTURE; PERFORMANCE; DYNAMICS; REMOVAL AB This study was conducted to determine the effect of stocking rate on yield of channel catfish Ictalurus punctatus and water quality in a mixed suspended-growth (biofloc) production system with zero water exchange. Channel catfish (National Warmwater Aquaculture Center 103 strain; average fish weight 13 g) were stocked into nine 35-m(2) tanks (28 m(3)/tank) at a rate of 2.9, 5.7, or 8.5 fish/m(2) for a 238-d grow-out period. One 1.865-kW blower for every three tanks supplied air continuously through a diffuser grid (constructed of 2.5-cm-diameter polyvinyl chloride pipe) on the bottom of each tank. Well water was added only periodically to replace evaporative losses. Fish in each tank were fed daily as much floating catfish feed (32% protein, extruded pellets) as they could consume in a 20-min period. Channel catfish net yield ranged from 0.99 to 3.71 kg/m(3) and increased linearly with stocking rate (r(2) = 0.87). At harvest, mean individual weight (0.54 kg/fish), survival (62.1%), specific growth rate (1.54% per day), and net feed conversion ratio (1.9) did not differ significantly among stocking rates. Cumulative feed addition averaged 6.66 kg/m(3) for the 8.5-fish/m(2) treatment, significantly greater than the 4.04 and 2.96 kg/m(3) for the 5.7- and 2.9-fish/m(2) treatments, respectively, which did not differ. Mean nitrate-nitrogen concentration was significantly higher and mean pH was significantly lower in the 8.5-fish/m(2) treatment compared with the other two treatments. There were no other differences in water quality among treatments. Total ammonia-nitrogen concentration was low throughout the experiment because of nitrification and phytoplankton uptake. This study demonstrated that high yields of channel catfish could be obtained by stocking up to 8.5 fish/m(2) in a mixed suspended-growth production system.

In experiment 1, hybrid catfish fingerlings with a mean initial weight of 65 g were stocked into ten 0.4-ha earthen ponds at a density of 12,355 fish/ha. In experiment 2, hybrid catfish fingerlings with the same mean initial weight as in experiment 1 were stocked into twenty 0.4-ha earthen ponds at densities of 18,532 and 24,710 fish/ha, respectively. Fish were fed once or twice daily to apparent satiation. In experiment 1, all fish were harvested in early September. In experiment 2, market-size fish (target size, >0.794 kg/fish) were selectively harvested in late September by means of an in-pond mechanical fish grader with the bar spacing set to 5.4 cm. All remaining fish were harvested in mid-June the next year. In both experiments, fish fed twice daily were given more feed, but there were no significant differences in weight gain per fish and net yield between fish fed once daily and those fed twice daily. Fish fed twice daily had a significantly higher feed conversion ratio. In experiment 2, a stocking density of 18,532 fish/ha resulted in higher weight gain and lower net yield than a stocking density of 24,710 fish/ha. Based on the results from this study, it appears to be efficient to stock hybrids at a density of 12,355 fish/ha, feed them once daily over a growing season, and "clean'' harvest them at the end of the season. However, a multiple-batch system may also be used to grow hybrids at densities of 18,532-24,710 fish/ha by means of a catfish grading system to remove market-size fish.

We examined past efforts through a comprehensive synthesis of peer-reviewed articles evaluating bull trout habitat relationships, and we used field data within classification tree analysis (CTA) to improve our understanding of the consistency of bull trout habitat use patterns. We performed CTA using reach-level habitat data collected from currently occupied stream networks (i.e., those within the current distribution of bull trout) and unoccupied stream networks where hierarchical filters (i.e., area and temperature) were met and from occupied areas where temperature criteria were exceeded. Results from the literature review demonstrated consistent results at the microhabitat and channel unit scales; indicated the importance of slow-velocity, deeper habitats; and, together with observed diel shifts, highlighted the importance of complex habitat regardless of scale or season. At the reach scale, however, our results indicated substantially less consistency in bull trout habitat relationships. Including maximum stream temperature into the CTA did not result in changes to the overall structure of the CTA; results from the CTA indicated that bull trout were found in reaches with larger substrate, deeper pools, and more cover, but the specific criteria differed along a gradient of stream depth. Our results indicated (1) important gaps in our knowledge regarding the role of substrate size in juvenile bull trout habitat use, (2) the need for elucidation of habitat use patterns in downstream reaches, which may act as critical overwintering habitat or migratory corridors, and (3) the need to incorporate sampling efficiencies in future bull trout habitat evaluations.

This myriad of groups has difficulty sharing data and scaling up stream habitat assessments to regional or national levels because of differences in their goals and data collection methods. To assess the performance of and potential for data sharing among monitoring groups, we compared measurements made by seven monitoring groups in 12 stream reaches in northeastern Oregon. We evaluated (1) the consistency (repeatability) of the measurements within each group, (2) the ability of the measurements to reveal environmental heterogeneity, (3) the compatibility of the measurements among monitoring groups, and (4) the relationships of the measurements to values determined from more intensive sampling (detailed measurements used as a standard for accuracy and precision in this study). Overall, we found that some stream attributes were consistently measured both within and among groups. Furthermore, for all but one group there was a moderate correlation (0.50) between the group measurements and the intensive values for at least 50% of the channel attributes. However, none of the monitoring groups were able to achieve high consistency for all measured stream attributes, and few of the measured attributes had the potential for being shared among all groups. Given the high cost of stream habitat monitoring, we suggest directing more effort to developing approaches that will increase the consistency and compatibility of measured stream attributes so that they will have broader utility. Ultimately, local monitoring programs should consider incorporating regional and national objectives so that data can be scaled up and the returns to limited monitoring dollars can be maximized across spatial scales.

Keith TI Smallmouth Bass Summer Habitat Use, Movement, and Survival in Response to Low Flow in the Illinois Bayou, Arkansas SO NORTH AMERICAN JOURNAL OF FISHERIES MANAGEMENT LA English DT Article ID DISCHARGE; SELECTION; STREAMS; RIVER AB The southwestern edge of the natural range of smallmouth bass Micropterus dolomieu contains streams that become disconnected pools during summer primarily owing to hydrogeologic conditions, including high evapotranspiration rates. These conditions may complicate fisheries management by affecting fish behavior or mortality rates. The objectives of this study were to characterize summer habitat use by smallmouth bass, estimate the changes in the extent of available habitat, describe summer movement patterns, and estimate summer survival rates. Radio transmitters were implanted into 60 smallmouth bass during May 2006, and the fish were tracked until October in the forks of the Illinois Bayou, which drains a portion of the Ozark National Forest. Habitat characteristics were measured as the summer progressed, and during this time most riffle-run habitat dried completely, resulting in a series of disconnected pools. The decreases in wetted area exceeded 55% in certain 2-km study reaches; however, smallmouth bass were consistently found at a median depth of 0.80 m. Boulder habitat was preferred when it was available; however, cobble, gravel, and bedrock substrates were also used. By July, velocity was below detection levels and water temperature occasionally exceeded 30 degrees C. The average distance moved by smallmouth bass was 270 m in May, decreasing to 54 m by July. The distances moved were greater on average but more variable in streams with larger losses of wetted area, as fish moved away from drying areas. The survival rate was lowest in the stream most accessible to anglers. Dryness appeared to increase mortality, as survival estimates were lower than expected from published studies of streams with continuous summer flow. The effective management of fisheries under such hydrologic conditions may require preserving continuous surface flow and the quality of remnant pools as well as implementing more restrictive harvest regulations in summer.

TI N-15 isotopic crop residue cycling studies and modeling suggest that IPCC methodologies to assess residue contributions to N2O-N emissions should be reevaluated SO NUTRIENT CYCLING IN AGROECOSYSTEMS LA English DT Article DE N-15; Crop residue exchange; DAYCENT, IPCC; N2O-N, nitrate leaching, nitrogen cycling ID NITROUS-OXIDE EMISSIONS; PRECISION CONSERVATION; IRRIGATED CROPS; SOIL; FLUXES; ROTATION; COLORADO; TILLAGE; METHANE; CORN AB It is difficult to quantify nitrogen (N) losses from agricultural systems; however, we can use N-15 isotopic techniques to conduct site-specific studies to increase our knowledge about N management and fate. Our manuscript analyzes two reviews of selected N-15 isotopic studies conducted to monitor N fate. The mechanistic foci of these studies include crop residue exchange and N fate in farming systems. Analysis of the data presented in these studies supports the claim that the average N losses are greater from inorganic N fertilizer inputs than organic crop residue N inputs. Additionally we conducted unique DAYCENT simulations of the effects of crop residue on nitrous oxide (N2O-N) emissions and nitrate (NO3-N) leaching. The simulation evaluations support the crop residue N-15 exchange studies and show lower leaching and N2O-N emissions from crop residue sources when compared to N fertilizer. The N-15 data suggest that the N in the crop residue pool must be recycled, and that this is a slower and more protected pool when compared to the readily available fertilizer. The results suggest that the Intergovernmental Panel on Climate Change (IPCC) methodology should be reevaluated to determine whether the direct and indirect N2O-N emission coefficients need to be lowered to reflect fewer N2O-N emissions from high C/N crop residue N inputs. The data suggest that accounting for nutrient cycling has implications for public policy associated with the United Nations Framework Convention on Climate Change (UNFCCC) and mitigation of N2O-N emissions from agricultural soils. Additional crop residue exchange studies, field N2O-N and NO3-N leaching and support model evaluations are needed across different worldwide agroecosystems.

Benoit, John TI Estimation of Fire Danger in Hawai'i Using Limited Weather Data and Simulation SO PACIFIC SCIENCE LA English DT Article ID SUCCESSION MODELS; FUEL MOISTURE; WILDLAND FIRE; RISK; CLASSIFICATION; DROUGHT; OREGON; SPREAD; CYCLE AB The presence of fire in Hawai'i has increased with introduction of nonnative grasses. Fire danger estimation using the National Fire Danger Rating System (NFDRS) typically requires 5 to 10 yr of data to determine percentile weather values and fire activity. The U.S. Army Pohakuloa Training Area in Hawai'i is located in the interface zone between windward and leeward weather conditions and needed to develop fire danger values but did not have sufficient weather or fire occurrence data. Use of simulation to estimate fire danger (expressed as fire risk) for areas with limited weather data was investigated. Influence of spatial resolution of weather information on fire risk was examined by comparing fire risk calculated using one or three weather stations and gridded weather predictions from the Mesoscale Spectral Model. Predicted gridded temperature was positively correlated with observed temperature; predicted and observed relative humidity were not significantly correlated. Simulated fire risk differed between weather data percentiles and between weather data resolutions. Predicted risk estimated from gridded weather data agreed more closely with observed risk estimated from weather data observed at all three remote automated weather stations. Correlation between simulated fire risk and the NFDRS Ignition Component was statistically significant for the single weather station simulations. Correlations between risk and the Ignition Component were not statistically significant for the three station and gridded weather data scenarios, which illustrates the difference between fire danger determined at broad spatial scales and fire risk resolved at finer spatial scales. Fire spread simulation modeling to estimate fire risk in areas with limited historical weather and fire occurrence data can provide finer-scale information than the NFDRS, which is better suited to larger, homogeneous areas with more complete fire and weather data. Values for the NFDRS Burning index were determined and incorporated into the wildland fire management plan for Paakuloa Training Area.

TI Phosphorus Dynamics in Two Poultry-Litter Amended Soils of Mississippi Under Three Management Systems SO PEDOSPHERE LA English DT Article DE conventional tillage; no-till; sediment phosphorus; soluble phosphorus ID AGRICULTURAL PHOSPHORUS; NUTRIENT RUNOFF; SURFACE RUNOFF; LOSSES; MANURE; QUALITY; FERTILIZER; OPTIONS; ISSUES AB An experiment arranged in a randomized complete block design with three replications was conducted on a Lexington soil (fine-silty, mixed, active, thermic, Ultic Hapludalfs) and a Loring soil (fine-silty, mixed, active, thermic, Oxyaquic Fragiudalfs) in Mississippi from September 1997 to September 2000 on 18 runoff plots under natural rainfall condition to study the phosphorus (P) dynamics in poultry litter amended soils under three management systems combining tillage and planting date treatments to identify effective management practices in southern U.S.A. The management systems in the study were: 1) tillage in the fall prior to litter application followed by a delayed planting of fall forages (CT-DP); 2) tillage followed by immediate planting of the fall forage with subsequent litter application (CT-IP); and 3) no-till with planting prior to litter application (NT-IP). The results indicated that there was significant increase in soil P after 3 years of poultry litter application for both Lexington and Loring soils (P < 0.05). Based on P budget analysis, the majority of P from poultry litter application (> 90%), was accumulated in both soils. In Loring soil, soluble P mass in the runoff was significantly higher from NT-IP than from CT-DP and CT-IP over the entire study period (P < 0.01). For both soils, there were no significant differences in sediment P mass between management systems. For Loring soil, CT-DP and CT-IP were effective management practices to mitigate negative effects due to poultry litter application. C1 [Beavers, B. W.; Liu, Z.; Cox, M. S.; Kingery, W.

TI Potential attractants for detecting and removing invading Gambian giant pouched rats (Cricetomys gambianus) SO PEST MANAGEMENT SCIENCE LA English DT Article DE attractants; Gambian giant pouched rat; Cricetomys gambianus; invasive species; trapping ID ERADICATION; ISLANDS; FLORIDA AB BACKGROUND: Native to Africa, Gambian giant pouched rats (Gambian rats; Cricetomys gambianus Waterh.) are a threatening invasive species on a Florida island, Grassy Key. Gambian giant pouched rats shifted from a domestic pet to invading species after suspected release from a pet breeder. Because of the large size of Gambian rats (weighing up to 2.8 kg), they pose a serious threat to native species (particularly nesting species) and agricultural crops, especially if Gambian rats invade mainland Florida. Also, Gambian rats pose a threat from disease, as they were implicated in a monkeypox outbreak in the midwestern United States in 2003. The United States Department of Agriculture's Wildlife Services has initiated eradication and detection efforts in the Florida Keys, but trapping the sparse population of Gambian rats has proven difficult. RESULTS: Fifteen attractants that could be used in traps for capturing or detecting single or paired Gambian rats were tested. It was found that conspecific scents (i.e. feces and urine) from other Gambian rats were the best treatment for attracting single and paired Gambian rats. Single Gambian rats explored more attractant types than paired Gambian rats. CONCLUSIONS: Effective attractants for use with Gambian rats have been identified, and multiple attractant types should be used to capture or detect the sparse population. It is recommended that mainly urine and feces from Gambian rats be used, but peanut butter, anise, ginger and fatty acid scent could also be useful for attracting the currently small population of Gambian rats on Grassy Key.

Currently, no pesticides are labeled for earthworms in the United States. Tea seed pellets (TSPs), a saponin-rich byproduct of Camellia oleifera Abel oil manufacture, were tested for expelling earthworms and reducing casts on creeping bentgrass turf. The fate of expelled worms, methods for removing them and impacts on pest and beneficial arthropods were also evaluated. RESULTS: Application of TSPs at 2.93 kg 100 m(-2), followed by irrigation, quickly expelled earthworms from the soil. A single application reduced casts by 80-95% for at least 5 weeks. Mowing or sweeping removed expelled earthworms from putting green surfaces. Most expelled earthworms burrowed down when transferred to untreated turf, but few survived. Bioassay-guided fractionation confirmed the vermicidal activity results from a mix of saponins. TSPs did not reduce the abundance of beneficial soil arthropods, nor did they control black cutworms or white grubs in treated turf. CONCLUSION: TSPs are an effective botanical vermicide that could be useful for selectively managing earthworm casts on closely mowed turfgrass. They might also be used to suppress earthworms in grassy strips alongside runways to reduce bird strike hazard at airports.

TI Sex attractant for the banana moth, Opogona sacchari Bojer (Lepidoptera: Tineidae): provisional identification and field evaluation SO PEST MANAGEMENT SCIENCE LA English DT Article DE Opogona sacchari; banana moth; attractant; octadecadienal ID QUARANTINE SECURITY; CLEARWING MOTH; PHEROMONE; SESIIDAE; 2,13-OCTADECADIENYL; ALCOHOLS; ACETATE; HAWAII AB BACKGROUND: The banana moth, Opogona sacchari Bojer, is a polyphagous agricultural pest in many tropical areas of the world. The identification of an attractant for male O. sacchari could offer new methods for detection, study and control. RESULTS: A compound extracted from female O. sacchari elicited responses from antennae of male moths. This compound was identified as a 2/3,(Z)13-octadecadienal by gas chromatography-mass spectrometry. An analog, 2/3,(Z)13-octadecadienol, was also detected in some extracts at roughly a 1 : 20 ratio (alcohol : aldehyde) but did not elicit responses from antennae of male moths. Electroantennograms of synthetic candidate dienals found the strongest responses from (Z,Z)-2,13-octadecadienal and (E, Z)-2,13-octadecadienal. In field trials, (E,Z)-2,13-octadecadienal attracted more male O. sacchari than (Z, Z)-2,13-octadecadienal. Attraction was not improved for either of these compounds when the corresponding stereoisomeric alcohol was added at ratios of 1 : 1, 1 : 10 or 1 : 100 (alcohol : aldehyde). Jackson sticky traps containing 250 mu g lures of (E,Z)-2,13-octadecadienal caught as many males as did traps holding virgin females. CONCLUSION: (E,Z)-2,13-octadecadienal has been identified as an attractant for O. sacchari males and can be used as a monitoring lure of populations of this moth.

Needle inoculation of Psc in the stem of coriander resulted in up to 94% plant mortality. The total biomass of inoculated plants decreased significantly four weeks after inoculation as compared to the control plants. Systemic infection was rapid and one week after inoculation a bacterial population of about 10(4) to 10(8) cfu g(-1) was isolated from different parts of the stems and roots. Surface contamination of coriander seed with Psc prior to planting resulted in low disease incidence (8%). However, spray inoculation of healthy coriander plants with Psc at concentrations equal to or greater than 10(3) CFU mL(-1) caused disease on the leaves, suggesting infection was common through the stomata. Splash dispersal of Psc was demonstrated, with disease being observed on surrounding coriander seedlings. Psc bacteria were dispersed up to 70 cm from the inoculum source.

Three strain-specific probes were developed using intergene sequences between the major and minor coat protein genes (CPi) in a multiplex reaction. Probe CPi-VT3 was designed for VT and T3 genotypes; probe CPi-T36 for T36 genotypes; and probe CPi-T36-NS to identify isolates in an outgroup clade of T36-like genotypes mild in California. Total nucleic acids extracted by chromatography oil silica particles, sodium dodecyl sulfate-potassium acetate, and CTV virion immunocapture all yielded high quality templates for real-time PCR detection of CTV. These assays successfully differentiated CTV isolates from California, Florida, and a large panel of CTV isolates from all international collection maintained in Beltsville, MD. The utility of the assay was validated using field isolates collected in California and Florida. C1 [Yokomi, R. K.] USDA ARS, Parlier, CA 93648 USA.

The objective of this study was to determine whether genetically differentiated groups of P triticina are currently present in South America and to compare the South American population with the previously characterized Population ill North America. In total, 130 isolates of R triticina from the wheat-growing regions of Argentina, Brazil, Chile, Peru. and Uruguay, mostly from the 1990s to 2008, were tested for virulence on 20 lines of wheat with single genes for leaf rust resistance and for molecular genotypes with 23 simple-sequence repeat (SSR) markers. After removal of isolates with identical virulence and SSR genotypes, 99 isolates were included for further analysis. Principal coordinate analysis plots indicated five different groups of isolates based on SSR genotypes that also differed for virulence to leaf rust resistance genes. All pairs of groups, except for one pair, were significantly differentiated for SSR genotypes according to R(ST) statistics. All but two pairs of groups were significantly differentiated for virulence phenotype according to Phi(PT) statistics. Isolates in all five groups had high values of fixation index for SSR alleles and linkage disequilibrium was high across all isolates that indicated the clonal reproduction of urediniospores. Only one of the five P. triticina groups from South America was differentiated for SSR genotypes from all of the six P triticina groups from North America. The high degree of similarity for SSR genotype of isolates from both South America and North America Suggested a common European origin of P. triticina that was introduced to both continents. The emergence of the same P. triticina virulence phenotypes with highly related SSR genotypes in the United States in 1996 and in Uruguay in 1999 indicated the likely intercontinental migration of these genotypes from Mexico to both South America and North America.

TI Characterization of physical and chemical properties of spent foundry sands pertinent to beneficial use in manufactured soils SO PLANT AND SOIL LA English DT Article DE Beneficial use; Manufactured soil; Spent foundry sand; Foundry sand ID AMENDMENT; REUSE AB As of 2007, of the 2,000 United States foundries, 93% produce ferrous or aluminum castings, generating 9.4 million tons of non-hazardous spent foundry sand (SFS) annually. Only 28% of the SFS is beneficially used. The U.S. EPA Resource Conservation Challenge identifies SFS as a priority material for beneficial use, with soil blending as a potential reuse option. The objectives of this work were to measure: (1) select chemical and physical properties important to soil quality and function and (2) total and soluble elemental content of 39 SFSs, in order to evaluate SFS suitability as a component in manufactured soils. Total elemental concentration of the SFS was lower than natural background soil levels for most elements analyzed, suggesting limited to no contamination of the virgin sand during metal casting. Pore water elemental concentrations were generally below detection. However, both total and soluble elemental content indicate a potential contribution of plant nutrients. Lettuce (Lactuca sativa) planted in SFS mixtures had a median germination rate of 96.9% relative to the control. Blending SFS at varying ratios with other materials will allow "tailoring" of a manufactured soil's chemical and physical properties to meet specific growing needs. The SFS organic carbon, clay, and plant nutrient content are benefits of SFS that may make them good candidates as manufactured soil components.

We studied the effects of atmospheric CO2 concentration (400 vs 780 mu L L-1), water content (15 vs 20% gravimetric soil moisture), and composition of semi-arid grassland species (perennial grasses Bouteloua gracilis, Hesperostipa comata, and Pascopyrum smithii; sub-shrub Artemisia frigida; invasive forb Linaria dalmatica grown in monoculture and all five species together) on CH4 consumption and N2O emission in a full factorial greenhouse experiment. We used a unique method where we measured microbial effects on CH4 consumption and N2O emission in isolation from effects of gas diffusivity. Microbially mediated CH4 consumption was significantly higher under elevated CO2 (by 20%), but was not affected by soil water content or plant species composition. Microbially mediated N2O emission was not significantly affected by elevated CO2, but was significantly higher with high water content (by 67%) and differed significantly among species. Treatment effects on CH4 consumption and N2O emission often could not be explained simply by differences in soil moisture, suggesting that treatment-induced changes in other soil and microbial properties played a role in causing these effects.

We used a gradient of endogenous soil N levels resulting from different management legacies and soil textures to investigate the effects of soil organic matter dynamics and N availability on soybean (Glycine max) N(2) fixation. Soybean N(2) fixation was estimated on 13 grain farm fields in central New York State by the (15)N natural abundance method using a non-nodulating soybean reference. A range of soil N fractions were measured to span the continuum from labile to more recalcitrant N pools. Soybean reliance on N(2) fixation ranged from 36% to 82% and total N(2) fixed in aboveground biomass ranged from 40 to 224 kg N ha(-1). Soil N pools were consistently inversely correlated with % N from fixation and the correlation was statistically significant for inorganic N and occluded particulate organic matter N. However, we also found that soil N uptake by N(2)-fixing soybeans relative to the non-nodulating isoline increased as soil N decreased, suggesting that N(2) fixation increased soil N scavenging in low fertility fields. We found weak evidence for internal regulation of N(2) fixation, because the inhibitory effects of soil N availability were secondary to the environmental and site characteristics, such as soil texture and corresponding soil characteristics that vary with texture, which affected soybean biomass, total N(2) fixation, and net N balance.

In an apparent example of this process, syringyl lignin, a fundamental building block of plant cell walls, occurs in two major plant lineages, lycophytes and angiosperms, which diverged from one another more than 400 million years ago. Here, we show that this convergence resulted from independent recruitment of lignin biosynthetic cytochrome P450-dependent monooxygenases that route cell wall monomers through related but distinct pathways in the two lineages. In contrast with angiosperms, in which syringyl lignin biosynthesis requires two phenylpropanoid meta-hydroxylases C3'H and F5H, the lycophyte Selaginella employs one phenylpropanoid dual meta-hydroxylase to bypass several steps of the canonical lignin biosynthetic pathway. Transgenic expression of the Selaginella hydroxylase in Arabidopsis thaliana dramatically reroutes its endogenous lignin biosynthetic pathway, yielding a novel lignin composition not previously identified in nature. Our findings demonstrate a unique case of convergent evolution via distinct biochemical strategies and suggest a new way to genetically reconstruct lignin biosynthesis in higher plants.

TI Integrative Transcript and Metabolite Analysis of Nutritionally Enhanced DE-ETIOLATED1 Downregulated Tomato Fruit SO PLANT CELL LA English DT Article ID ARABIDOPSIS-THALIANA; SIGNAL-TRANSDUCTION; PHYTOENE SYNTHASE; GENE-EXPRESSION; CHLOROPLAST DEVELOPMENT; VEGETATIVE DEVELOPMENT; BIOSYNTHETIC-PATHWAY; GENOME EXPRESSION; MICROARRAY DATA; HIGHER-PLANTS AB Fruit-specific downregulation of the DE-ETIOLATED1 (DET1) gene product results in tomato fruits (Solanum lycopersicum) containing enhanced nutritional antioxidants, with no detrimental effects on yield. In an attempt to further our understanding of how modulation of this gene leads to improved quality traits, detailed targeted and multilevel omic characterization has been performed. Metabolite profiling revealed quantitative increases in carotenoid, tocopherol, phenylpropanoids, flavonoids, and anthocyanidins. Qualitative differences could also be identified within the phenolics, including unique formation in fruit pericarp tissues. These changes resulted in increased total antioxidant content both in the polar and nonpolar fractions. Increased transcription of key biosynthetic genes is a likely mechanism producing elevated phenolic-based metabolites. By contrast, high levels of isoprenoids do not appear to result from transcriptional regulation but are more likely related to plastid-based parameters, such as increased plastid volume per cell. Parallel metabolomic and transcriptomic analyses reveal the widespread effects of DET1 downregulation on diverse sectors of metabolism and sites of synthesis. Correlation analysis of transcripts and metabolites independently indicated strong coresponses within and between related pathways/processes. Interestingly, despite the fact that secondary metabolites were the most severely affected in ripe tomato fruit, our integrative analyses suggest that the coordinated activation of core metabolic processes in cell types amenable to plastid biogenesis is the main effect of DET1 loss of function.

Agrobacterium tumefaciens strain EHA105 harboring an RNAi plasmid with the black cherry AGAMOUS (AG) gene was used. Bacteria were induced for 12 h with 200 mu M acetosyringone for vir gene induction before leaf explant inoculation. Explants were co-cultured for 3 days, and then cultured on woody plant medium supplemented with 9.08 mu M thidiazuron, 1.07 mu M napthaleneacetic acid, 60 mu M silver thiosulphate, 3% sucrose, plus 200 mg l(-1) timentin in darkness for 3 weeks. Regenerating shoots were selected 27 days after initial co-culture, on Murashige and Skoog medium with 3% sucrose, 8.88 mu M 6-benzylaminopurine, 0.49 mu M indole-3-butyric acid, 0.29 mu M gibberellic acid, 200 mg l(-1) timentin, and 30 mg l(-1) kanamycin for five subcultures. After 5-6 months of selection, transformation efficiencies were determined, based on polymerase chain reaction (PCR) analysis of individual putative transformed shoots relative to the initial number of leaf explants tested. The transformation efficiency was 1.2%. Southern blot analysis of three out of four PCR-positive shoots confirmed the presence of the neomycin phosphotransferase and AG genes. Transgenic shoots were rooted (37.5%), but some shoot tips and leaves deteriorated or died, making acclimatization of rooted transgenic plants difficult. This transformation, regeneration, and rooting protocol for developing transgenic black cherry will continue to be evaluated in future experiments, in order to optimize the system for several mature black cherry genotypes.

TI Identification and Evaluation of Sources of Resistance to Stem Rust Race Ug99 in Wheat SO PLANT DISEASE LA English DT Article ID F-SP TRITICI; PUCCINIA-GRAMINIS; VIRULENCE; TTKS; SR31 AB The race Ug99 of Puccinia graminis f. sp tritici causing stem rust disease of wheat was initially identified in Uganda in 1998. It was designated as TTKSK based oil the North American nomenclature and has Caused periodic losses to wheat crops in East Africa, Ug99 has recently moved out of Africa to Yemen and West Asia. The most effective approach to prevent losses from stem rust is through the deployment of resistant cultivars. More effective sources of resistance need to be identified and incorporated in the existing commercial cultivars. The first Stem Rust Resistance Screening Nursery (1stSRRSN) assembled by the International Maize and Wheat Improvement Center (CIMMYT) consisted of elite and advanced CIMMYT bread wheat lines and was evaluated for resistance to Ug99 in Njoro, Kenya for four consecutive seasons, (2005 to 2007). Seedling reactions were determined in the greenhouse at (lie Cereal Disease Laboratory, St. Paid, MN. Two race-specific genes, Sr24 and Sr25, were found to confer resistance to Ug99, although Sr24 became ineffective to a mutant race of Ug99. TTKST, in 2007. Three previously uncharacterized genes, one each from synthetic wheat, Chinese germplasm, and other genetic backgrounds, were detected, Although 30% of the screened lines were susceptible in the seedling stage, these lines displayed various levels of adult plant resistance (APR) in the Field tests. Presence of the APR gene Sr2, identified based on the pseudo-black chaff phenotype on glumes and darkened internode, was common in wheat lines with APR. The information on the resistance identified in the 1stSRRSN constitutes an important source for breeding wheat for durable resistance.

The isolates were compared to a set of 13 previously characterized P triticina isolates from either durum or common wheat. Clustering based on virulence phenotypes and SSR genotypes grouped the Italian P. triticina isolates into three groups. In the First group, the isolates had virulence phenotypes and SSR genotypes, that were similar to the isolates collected from durum wheat. Isolates in the second group were unique because they had virulence similar to the isolates from common wheat but were distinct for SSR genotypes compared to the isolates from durum wheat and from common wheat. Isolates in the third group had virulence phenotypes and SSR genotypes closely related to the isolates from common wheat. The isolates were grouped based on the known or assumed host of origin. virulence phenotype. and SSR genotypes. Measures of F(ST) and R(ST) for SSR genotypes. and Phi(ST) for virulence phenotype were significant. which indicated differentiation among the three groups of isolates.

A degree-day model that forecasts the first emergence of shoots systemically infected with P. humuli (termed basal spikes) and a risk index for secondary spread of the disease Were evaluated over four seasons, in western Oregon. In surveys conducted in 34 hot) yards, the predicted first spike emergence occurred on average 11.6 days (median 12 days) after spike emergence using a simple average degree-day model (base temperature 6.5 degrees C) developed for Washington State. Predictions based on a single sine model (base temperature 6 degrees C) provided oil average 4.9 days (median -0.5 days) of advanced warning, before the first spike emerged. Downy mildew severity in a previous season was negatively correlated with the degree-day emergence date of spikes the following year (r = -0.39). In experimental plots, disease severity was significantly greater where fungicide applications were timed using a risk index compared to routine fungicide applications in 2005 and 2007, but statistically similar between these treatments in 2006 and 2008. However, in 2006, 2007, and 2008. treatments initiated using a degree-day threshold resulted in in area under the disease progress curve similar to or smaller than in treatments with routine fungicide applications. Model-aided treatments required four fewer fungicide applications compared to routine fungicide applications. These Studies indicate that downy mildew Can be managed effectively), with fewer fungicide applications than currently made by hop growers in this region if fungicide applications are timed to Coincide with the predicted emergence of basal,pikes and Subsequent disease risk forecasts.

TI An Assessment of the Genetic Diversity in a Field Population of Phytophthora nicotianae with a Changing Race Structure SO PLANT DISEASE LA English DT Article ID FRAGMENT-LENGTH-POLYMORPHISM; POLYMERASE-CHAIN-REACTION; RIBOSOMAL DNA; NESTED-PCR; PARASITICA; TOBACCO; CAPSICI; AFLP; MITOCHONDRIAL; CACTORUM AB One hundred fifty-three isolates of Phytophthora nicotianae that were collected over a 4-year period from single field were subjected to amplified fragment length polymorphism (AFLP) analysis to investigate the effect of different types of resistance in tobacco (Nicotiana tabacum) on genetic diversity in the pathogen population. No race 1 isolates were detected ill the field prior to initiating the study, bill the race was present ill multiple plots by the end of the 4-year period. There were 102 race 0 isolates and 51 race 1 isolates characterized. Seventy-six of the 153 isolates had a unique AFLP profile, whereas the remaining 77 isolates were represented by 27 AFLP profiles shared by at least two isolates. Isolates of both races were found in both the unique and shared AFLP profile groups. Twenty-three of the AFLP profiles were detected in multiple years, indicating a clonal component to the pathogen population. Race 1 isolates that we re detected over multiple years were always obtained from the same plot. No race 1 profile was found in more than one plot, confirming the hypothesis that the multiple occurrences of the race throughout the field were the result of independent events and not pathogen spread. Three identical race 0 AFLP profiles occurred in noncontiguous plots. and in each case. the plots contained the same partially resistant variety. Cluster analysis provided a high level of bootstrap support for 41 isolates in 19 clusters that grouped primarily by race and rotation treatment. Estimates of genetic diversity ranged from 0.365 to 0.831 and varied depending on tobacco cultivar planted and race. When averaged over all treatments. diversity in race 1 isolates was lower than in race 0 isolates at the end Of each season. Deployment of single-gene resistance initially decreased. genetic diversity of the population, but the diversity increased each year, indicating, the pathogen was adapting to the host genotypes deployed in the field.

TI Comparative Infectivity of Cronartium ribicola Aeciospores and Urediniospores in Genotypes of Ribes nigrum SO PLANT DISEASE LA English DT Article ID PINE BLISTER RUST; NORTH-AMERICA; 1ST REPORT; PEDICULARIS; RESISTANCE; FUNGUS; HOSTS; GENE AB Hosts for the fungus Cronartium ribicola, causal agent of white pine blister rust (WPBR), include five-needle pines as aecial hosts, and currants and gooseberries as uredinial/telial hosts. Aeciospores produced on diseased pine, and urediniospores produced on diseased Ribes plants, can infect Ribes foliage. Resistance and susceptibility for both spore types have been reported for Ribes however. the comparative infectivity of these spore types oil clonal Ribes nigrum genotypes is under-described. Immunity. resistance, and Susceptibility to WPBR resides at a clonal level in Ribes. Previous studies have emphasized fungal diversity or forestry considerations, rather than horticultural aspects. The objective of this study was to determine if aeciospores and urediniospores were equally infective to specific genotypes of black currant. Ribes nigrum, with differential responses. A family of 51 black currant genotypes front a cross between a known-immune cultivar containing the Cr gene and a susceptible cultivar Was examined. Single-leaf softwood cuttings of each of these genotypes were artificially inoculated with a spore solution and incubated in airtight plastic containers within a growth chamber. Inoculations were replicated three times for each spore type, Twenty-two of the F(1) genotypes did not develop uredia after artificial inoculation. These may be immune: 22 developed uredia after exposure to both types of inoculum, and were susceptible; whereas seven exhibited differential responses and may have some mechanism for resistance to WPBR other than the Cr gene. The infectivity of aeciospores and urediniospores was not significantly different oil specific Ribes genotypes. Either spore type can therefore be considered equally effective as inoculum when screeing for WPBR resistance or immunity in horticultural settings. C1 [Hummer, K.

TI Functional analysis of a tomato salicylic acid methyl transferase and its role in synthesis of the flavor volatile methyl salicylate SO PLANT JOURNAL LA English DT Article DE aroma; phytohormones; volatile synthesis ID SYSTEMIC ACQUIRED-RESISTANCE; VAPOR-PHASE EXTRACTION; PLANT INNATE IMMUNITY; CARBOXYL METHYLTRANSFERASE; ARABIDOPSIS-THALIANA; JASMONIC ACID; PATHOGEN; DEFENSE; GENE; IDENTIFICATION AB P>Methyl salicylate (MeSA) is a volatile plant secondary metabolite that is an important contributor to taste and scent of many fruits and flowers. It is synthesized from salicylic acid (SA), a phytohormone that contributes to plant pathogen defense. MeSA is synthesized by members of a family of O-methyltransferases. In order to elaborate the mechanism of MeSA synthesis in tomato, we screened a set of O-methyltransferases for activity against multiple substrates. An enzyme that specifically catalyzes methylation of SA, SlSAMT, as well as enzymes that act upon jasmonic acid and indole-3-acetic acid were identified. Analyses of transgenic over- and under-producing lines validated the function of SlSAMT in vivo. The SlSAMT gene was mapped to a position near the bottom of chromosome 9. Analysis of MeSA emissions from an introgression population derived from a cross with Solanum pennellii revealed a quantitative trait locus (QTL) linked to higher fruit methyl salicylate emissions. The higher MeSA emissions associate with significantly higher SpSAMT expression, consistent with SAMT gene expression being rate limiting for ripening-associated MeSA emissions. Transgenic plants that constitutively over-produce MeSA exhibited only slightly delayed symptom development following infection with the disease-causing bacterial pathogen, Xanthomonas campestris pv. vesicatoria (Xcv). Unexpectedly, pathogen-challenged leaves accumulated significantly higher levels of SA as well as glycosylated forms of SA and MeSA, indicating a disruption in control of the SA-related metabolite pool. Taken together, the results indicate that SlSAMT is critical for methyl salicylate synthesis and methyl salicylate, in turn, likely has an important role in controlling SA synthesis.

Two genomic libraries from S. pennellii were screened with 104 colocated markers from five selected genomic regions, and a total of 614 bacterial artificial chromosome (BAC)/cosmids were identified as seed clones. Integration of sequence data with the genetic and physical maps of Solanum lycopersicum facilitated the anchoring of 374 of these BAC/cosmid clones. The analysis of this information resulted in a genome-wide map of a nondomesticated plant species and covers 10% of the physical distance of the selected regions corresponding to approximately 1% of the wild tomato genome. Comparative analyses revealed that S. pennellii and domesticated tomato genomes can be considered as largely colinear. A total of 1,238,705 bp from both BAC/cosmid ends and nine large insert clones were sequenced, annotated, and functionally categorized. The sequence data allowed the evaluation of the level of polymorphism between the wild and cultivated tomato species. An exhaustive microsynteny analysis allowed us to estimate the divergence date of S. pennellii and S. lycopersicum at 2.7 million years ago. The combined results serve as a reference for comparative studies both at the macrosyntenic and microsyntenic levels. They also provide a valuable tool for fine-mapping of quantitative trait loci in tomato. Furthermore, they will contribute to a deeper understanding of the regulatory factors underpinning metabolism and hence defining crop chemical composition.

TI Systems Analysis of Seed Filling in Arabidopsis: Using General Linear Modeling to Assess Concordance of Transcript and Protein Expression SO PLANT PHYSIOLOGY LA English DT Article ID MESSENGER-RNA; SACCHAROMYCES-CEREVISIAE; PROTEOMIC ANALYSIS; COPY NUMBERS; DYNAMICS; PROFILES; NETWORKS; DATABASE; YEAST AB Previous systems analyses in plants have focused on a single developmental stage or time point, although it is often important to additionally consider time-index changes. During seed development a cascade of events occurs within a relatively brief time scale. We have collected protein and transcript expression data from five sequential stages of Arabidopsis (Arabidopsis thaliana) seed development encompassing the period of reserve polymer accumulation. Protein expression profiling employed two-dimensional gel electrophoresis coupled with tandem mass spectrometry, while transcript profiling used oligonucleotide microarrays. Analyses in biological triplicate yielded robust expression information for 523 proteins and 22,746 genes across the five developmental stages, and established 319 protein/transcript pairs for subsequent pattern analysis. General linear modeling was used to evaluate the protein/transcript expression patterns. Overall, application of this statistical assessment technique showed concurrence for a slight majority (56%) of expression pairs. Many specific examples of discordant protein/transcript expression patterns were detected, suggesting that this approach will be useful in revealing examples of post-transcriptional regulation.

Fine-tuned interactions between these two processes are therefore necessary but poorly understood. To better understand such cross talk in the model plant Arabidopsis (Arabidopsis thaliana), we first established optimized concentrations of drugs that interfere with either endomembrane trafficking or the actin cytoskeleton, then examined pollen tube growth using fluorescent protein markers that label transport vesicles, endosomes, or the actin cytoskeleton. Both brefeldin A (BFA) and wortmannin disturbed the motility and structural integrity of ARA7-but not ARA6-labeled endosomes, suggesting heterogeneity of the endosomal populations. Disrupting endomembrane trafficking by BFA or wortmannin perturbed actin polymerization at the apical region but not in the longitudinal actin cables in the shank. The interference of BFA/wortmannin with actin polymerization was progressive rather than rapid, suggesting an indirect effect, possibly due to perturbed endomembrane trafficking of certain membrane-localized signaling proteins. Both the actin depolymerization drug latrunculin B and the actin stabilization drug jasplakinolide rapidly disrupted transport of secretory vesicles, but each drug caused distinct responses on different endosomal populations labeled by ARA6 or ARA7, indicating that a dynamic actin cytoskeleton was critical for some steps in endomembrane trafficking. Our results provide evidence of cross talk between endomembrane trafficking and the actin cytoskeleton in pollen tubes.

Contamination of food with the trichothecene mycotoxin deoxynivalenol (DON) produced by Fusarium is a major health concern for humans and animals because trichothecenes are potent cytotoxins of eukaryotic cells. Trichothecene mycotoxins inhibit translation by targeting ribosomal protein L3 at the peptidyltransferase center. We previously showed that expression of an N-terminal fragment of yeast L3 (L3 Delta) in transgenic tobacco plants reduced the toxicity of DON. Here, we produced transgenic wheat plants that express the same yeast 13 (L3 Delta) fragment and evaluated their susceptibility to Fusarium graminearum infection and their ability to accumulate DON. Following F. graminearum infection in greenhouse tests, two transgenic wheat lines expressing the highest levels of L3 Delta showed reductions in disease severity and kernel DON levels, compared to non-transformed plants. In a field test, a transgenic wheat line with the highest L3 Delta expression controlled by the maize Ubi1 promoter had significant reductions in visually scabby kernels and kernel DON levels. These results demonstrate that expression of a modified form of the ribosomal protein that is the target of DON can improve FHB resistance in wheat. (C) 2010 Elsevier Ireland Ltd.

To conserve P. tabacum and to evaluate possible reintroduction, we studied its historical distribution and conducted field surveys of both its biotic and physical environment. We used detrended correspondence analysis and canonical correspondence analysis to investigate the plant community structure and to identify the major environmental factors associated with its presence at eight sites and absence from three other sites where it formerly grew. The results revealed differences in community structure among sites and close correlations between species composition and environmental conditions. The data indicate that P. tabacum has special ecological requirements, including alkaline soil, low soil content of N, P, K and organic matter, low light, a high soil water content and high relative humidity, and a high atmospheric CO(2) concentration. Soil K content, relative humidity and atmospheric CO(2) concentration were the three variables most strongly associated with the vegetation composition and structure of the 11 sites. It appears that as a result of reductions in humidity, some of the historical localities of P. tabacum may no longer be suitable for reintroduction. Pilea notata, Pteris cretica var. nervosa and two moss species, Heteroscyphus coalitus and Gymnostomiella longinervis, were strongly associated with P. tabacum. The first two plants could be useful as indicators of suitable environments for P. tabacum, and the moss species could be useful as nurse plants for the reintroduction of P. tabacum into wild habitats.

To ascertain whether a chimeric promoter with similar tissue specificity can be created for species other than Arabidopsis, we isolated two similar but distinct AG second intron/enhancers from tobacco (NtAGI-1 and NtAGI-2) and analyzed their ability to drive floral organ-specific expression in plants through the creation of forward- and reverse-oriented chimeric promoters, fNtAGIP1, rNtAGIP1, fNtAGIP2 and rNtAGIP2. Analyses of transgenic plants bearing each respective promoter fused to the beta-glucuronidase (GUS) reporter gene showed that all four promoters are able, like the AtAGIP, to drive very similar carpel- and stamen-specific expression without any leaky activity in vegetative tissues. These results indicate that unlike their counterparts in rice and maize, the tobacco NtAGI-1 and NtAGI-2 enhancers share a highly conserved regulatory function. Interestingly, all four promoters display additional tissue specificity in petals, and their activity is influenced by the orientation of the incorporated enhancer, with reverse-oriented enhancers exhibiting approximately double the effectiveness of forward-oriented enhancers. These properties are novel and have not been observed with the AtAGIP promoter in Arabidopsis. As expected, these highly specific promoters can also direct the expression of the DT-A cytotoxic gene exclusively in carpels, stamens and petals, resulting in complete sterility through the precise ablation of targeted floral organs. Further analyses demonstrated that the resulting trait is mitotically stable, which is critical for the long-term containment of seed-, pollen- and fruit-mediated gene flow in field conditions.

TI Association and Linkage Analysis of Aluminum Tolerance Genes in Maize SO PLOS ONE LA English DT Article ID ACID-SOIL TOLERANCE; GENOTYPIC DIFFERENCES; MALATE TRANSPORTERS; ROOT ELONGATION; COMPLEX TRAITS; TROPICAL MAIZE; RESISTANCE; PLANTS; TOXICITY; ARABIDOPSIS AB Background: Aluminum (Al) toxicity is a major worldwide constraint to crop productivity on acidic soils. Al becomes soluble at low pH, inhibiting root growth and severely reducing yields. Maize is an important staple food and commodity crop in acidic soil regions, especially in South America and Africa where these soils are very common. Al exclusion and intracellular tolerance have been suggested as two important mechanisms for Al tolerance in maize, but little is known about the underlying genetics. Methodology: An association panel of 282 diverse maize inbred lines and three F-2 linkage populations with approximately 200 individuals each were used to study genetic variation in this complex trait. Al tolerance was measured as net root growth in nutrient solution under Al stress, which exhibited a wide range of variation between lines. Comparative and physiological genomics-based approaches were used to select 21 candidate genes for evaluation by association analysis. Conclusions: Six candidate genes had significant results from association analysis, but only four were confirmed by linkage analysis as putatively contributing to Al tolerance: Zea mays AltSB like (ZmASL), Zea mays aluminum-activated malate transporter2 (ALMT2), S-adenosyl-L-homocysteinase (SAHH), and Malic Enzyme (ME). These four candidate genes are high priority subjects for follow-up biochemical and physiological studies on the mechanisms of Al tolerance in maize. Immediately, elite haplotype-specific molecular markers can be developed for these four genes and used for efficient marker-assisted selection of superior alleles in Al tolerance maize breeding programs.

TI Genetic Analysis of Central Carbon Metabolism Unveils an Amino Acid Substitution That Alters Maize NAD-Dependent Isocitrate Dehydrogenase Activity SO PLOS ONE LA English DT Article ID NITROGEN USE EFFICIENCY; MAYS SSP PARVIGLUMIS; LINKAGE DISEQUILIBRIUM; ENZYME-ACTIVITIES; DROSOPHILA-MELANOGASTER; ALCOHOL-DEHYDROGENASE; CANDIDATE GENES; HIGHER-PLANTS; ASSOCIATION; ARABIDOPSIS AB Background: Central carbon metabolism (CCM) is a fundamental component of life. The participating genes and enzymes are thought to be structurally and functionally conserved across and within species. Association mapping utilizes a rich history of mutation and recombination to achieve high resolution mapping. Therefore, applying association mapping in maize (Zea mays ssp. mays), the most diverse model crop species, to study the genetics of CCM is a particularly attractive system. Methodology/Principal Findings: We used a maize diversity panel to test the CCM functional conservation. We found heritable variation in enzyme activity for every enzyme tested. One of these enzymes was the NAD-dependent isocitrate dehydrogenase (IDH, E.C. 1.1.1.41), in which we identified a novel amino-acid substitution in a phylogenetically conserved site. Using candidate gene association mapping, we identified that this non-synonymous polymorphism was associated with IDH activity variation. The proposed mechanism for the IDH activity variation includes additional components regulating protein level. With the comparison of sequences from maize and teosinte (Zea mays ssp. Parviglumis), the maize wild ancestor, we found that some CCM genes had also been targeted for selection during maize domestication. Conclusions/Significance: Our results demonstrate the efficacy of association mapping for dissecting natural variation in primary metabolic pathways. The considerable genetic diversity observed in maize CCM genes underlies heritable phenotypic variation in enzyme activities and can be useful to identify putative functional sites.

Stress-induced reactive oxygen species (ROS) can be detrimental to the fruit, and ascorbic acid (AsA) is involved in many of the antioxidant pathways that detoxify ROS. An inclusive study to characterize AsA dynamics in 'Delicious,"Golden Delicious,' and 'Fuji' apples during pre- and post-harvest development was performed. AsA was quantified in fruit harvested prior to, at, and following attainment of physiological maturity. Fruit harvested at physiological maturity was stored in air at 0.5 degrees C and AsA was monitored at monthly intervals. AsA content in peel exceeded that in cortex for all cultivars at all sampling points. AsA in cortex declined early in fruit development and remained low relative to peel throughout development and storage. During development there was a slight increase in the quantity of AsA at physiological maturity, which correlates with an increase in internal ethylene. 'Delicious' apples harvested at 161 d after full bloom (DAFB) had the highest quantity of AsA, followed by 'Golden Delicious' at 149 DAFB and 'Fuji' at 178 DAFB. AsA localization in fruit sections stained with silver nitrate supported the analytical data obtained via HPLC and revealed AsA localizes to the core line and vascular bundles later in fruit development, and this pattern continues during cold storage.

TI Ethylene production and ethylene effects on respiration rate of postharvest sugarbeet roots SO POSTHARVEST BIOLOGY AND TECHNOLOGY LA English DT Article DE Aminoethoxyvinylglycine; Beta vulgaris; 1-Methylcyclopropene; Silver thiosulfate ID VARIETIES; STORAGE; LOSSES; PLANTS AB Ethylene elevates respiration, is induced by wounding, and contributes to wound-induced respiration in most postharvest plant products. Ethylene production and its effects on respiration rate, however, have not been determined during storage of sugarbeet (Beta vulgaris L.) root, even though any elevation in respiration due to ethylene would increase storage losses and reduce postharvest quality. To determine the effect of ethylene on sugarbeet root storage respiration rate, sugarbeet root ethylene production was quantified, and the effects of exogenous ethylene, an ethylene biosynthesis inhibitor, and ethylene response inhibitors on root respiration rate were determined using uninjured, severely injured, and conventionally harvested roots. Ethylene production was low (0.045-0.047 pmol kg(-1) s(-1)) in uninjured and conventionally harvested and piled roots. Consequently, ethylene concentrations in commercial piles 0-67 d after piling were low, ranging from <0.001 to 0.054 mu LL(-1). Exogenous ethylene at concentrations of 0.020-14 mu LL(-1) increased root respiration. The increase in respiration rate, however, was transient at ethylene concentrations <= 0.11 mu LL(-1) suggesting that any ethylene effects on respiration rate in commercial piles would be short term. Severe injury induced ethylene production an average of 3.7-fold and increased respiration rate 3-4 d after injury. Wound-induced ethylene production, however, was not directly responsible for wound-induced respiration since elimination of wound-induced ethylene production by the ethylene synthesis inhibitor aminoethoxyvinylglycine had no effect on wound-induced respiration. The ethylene response inhibitors 1-methylcyclopropene (1-MCP) and silver thiosulfate reduced wound-induced respiration 3-4 d after injury when applied after wounding. A portion of the increase in respiration due to wounding, therefore, required ethylene perception. However, when applied prior to wounding, 1-MCP elevated wound-induced respiration 3-4 d after injury, suggesting that blockage of ethylene receptors prior to injury was ineffective at eliminating ethylene perception after wounding, possibly due to the synthesis of new receptors after the injury. Moreover, 1-MCP effects on root respiration rate occurred only when roots were severely injured; 1-MCP had no effect on respiration rate of uninjured or conventionally harvested roots. Postharvest sugarbeet roots, therefore, produce ethylene, increase ethylene production in response to wounding, and respond to exogenous ethylene with an increase in respiration rate, but ethylene production and ethylene effects on root respiration rate are likely to be small under commercial storage conditions and of limited economic significance.

We tested the ability of thidiazuron (TDZ). a phenyl-urea compound with cytokinin-like activity, to improve iris flower opening and longevity. A postharvest pulse with 0.2-1 mM TDZ for 6-24 h at 0 or 20 degrees C extended the vase life of flowers by up to 1.5 d relative to control (0 mM TDZ) stems in water. TDZ treatment also stimulated growth of the pedicel and ovary by tip to 2.5 cm that, in turn, led to more complete opening of flowers. Inclusion of 1 mM gibberellic acid (GA(3)) in the TDZ pulsing solution did not extend vase life further but did increase flower shoot elongation by an additional 1.0 cm. Provision of 20% sucrose with the TDZ plug GA(3) treatment had an additive effect, increasing vase life and shoot growth by a further 0.8 d and 1.0 cm, respectively. Pulsing stems with this combined treatment prior to storing flowers dry for 14 d at 0 degrees C provided maximum flower opening and display life after storage. Treatment with 0.5 mM TDZ stimulated a significant increase in ethylene production by flowers during their opening. (C) 2009 Elsevier B.V. All rights reserved.

TI Modified pressure imaging for egg crack detection and resulting egg quality SO POULTRY SCIENCE LA English DT Article DE shell egg; crack; detection; imaging; quality ID SALMONELLA-ENTERITIDIS; FREQUENCY-ANALYSIS; SHELL EGGS; PENETRATION; STRENGTH; STORAGE AB Cracks in the shell surface compromise the primary barrier for external microbial contamination of the egg. Microcracks are very small cracks in the shell surface that are difficult to detect by human graders. New technology has been developed that uses modified pressure and imaging to detect microcracks in eggs. Research has shown the system to have an accuracy of 99.6% in detecting both cracked and intact eggs. A study was undertaken to determine if quality differences existed between modified pressure imaged and control eggs during extended cold storage. Three replicates were conducted with eggs stored at 4 C for 5 wk with weekly quality testing. The physical quality factors monitored were Haugh units, albumen height, egg weight, shell strength, vitelline membrane strength and elasticity, and whole egg total solids. All measurements were conducted on individual eggs (12/treatments per replicate) each week with the exception of whole egg solids, which were determined from 3 pools (4 eggs each)/treatment per replicate each week. Percentage of whole egg total solids was the only significant difference (P < 0.05) between treatments (23.65% modified pressure imaged and 23.47% control). There was a significant difference (P < 0.05) for egg weight between replicates (60.82, 58.02, and 60.58 g for replicates 1, 2, and 3, respectively). Therefore, imaging eggs in the modified pressure system for microcrack detection did not alter egg quality during extended cold storage. Utilizing the modified pressure crack detection technology would result in fewer cracked eggs reaching the consumer, consequently enhancing food safety without affecting product quality.

Through natural selection, the population preserves and accumulates traits that are beneficial and rejects those that are detrimental in their prevailing environments. The surviving populations are able to contribute more genes associated with beneficial traits for increased fitness to subsequent generations. Natural selection is slow but constant; working over multiple generations, the changes to the population often appear silent or undetectable at a given point in history. Chickens were domesticated from the wild red jungle fowl. The principle of domestication of chickens, as well as other farm animals, by humans is similar to that of natural selection: selecting the best animals with the highest survivability and reproducibility (artificial selection). Compared with natural selection, the process of artificial selection is motivated by human needs and acts more rapidly with more visible results over a short time period. This process has been further accelerated following the development of current breeding programs and the emergence of specialized breeding companies. A laying hen, for example, produces more than 300 hundred eggs a year, whereas a jungle fowl lays 4 to 6 eggs in a year. During the domestication process, chickens retained their capability to adapt to their housing environments, which is usually achieved by genetic changes occurring with each subsequent generation. Genes control the behavioral, physiological, immunological, and psychological responses of animals to stressors, including environmental stimulations. With advances in understanding of genetic mediation of animal physiology and behavior and the discovery of the genome sequences of many species, animal production breeding programs can be improved in both speed and efficiency. Modern chicken breeding programs have the potential to be operated successfully in the breeding of tomorrow's chickens with high production efficiency and optimal welfare, resulting from resistance to stress, disease, or both.

If this trend is to be maintained, solutions must be found to improve resistance of chickens to disease, which often is weakened by stressful conditions. In poultry, stress-induced immunosuppression is manifested by failures in vaccination and increased morbidity and mortality of flocks. Currently, several modern cellular and molecular approaches are being used to explore the status of the immune system during stress and disease. It is likely that these new techniques will lead to the development of new strategies for preventing and controlling immunosuppression in poultry. Using quantitative reverse transcription-PCR assays, a broad spectrum of cytokine, chemokine, and their receptor genes can be quantified in birds and then be used as markers to assess the effects of stress on the immune system. Currently, we are investigating immune and endocrine interactions in the chicken, in particular the cells and molecules that are known to be involved in such interactions in mammals. We have evaluated the effects of corticosterone administration in drinking water on peripheral lymphocyte and heterophil cytokine and chemokine gene profiles. In particular, there seems to be effects on cytokine and chemokine mRNA expression levels in both lymphocytes and heterophils, especially expression of the proinflammatory cytokines interleukin (IL)-1 beta, IL-6, and IL-18 and chemokines C-C motif, ligand 1 inflammatory (CCLi1); C-C motif, ligand 2 inflammatory (CCLi2); C-C motif, ligand 5 (CCL5); C-C motif, ligand 16 (CCL16); C-X-C motif ligand 1 inflammatory (CXCLi1); and C-X-C motif ligand 2 inflammatory (CXCLi2), which are initially upregulated and are potentially involved in modulating the adaptive immune response. A chronic treatment with corticosterone downregulates proinflammatory cytokines and chemokines, suggesting that the delayed effects of chronic stress can suppress the immune response. Messenger RNA expression levels of transforming growth factor-beta 4 (TGF-beta 4) are also upregulated in cortisosterone-treated birds. It appears that the balance between T-helper (Th) 1 and Th2/T regulatory cytokine production is altered in conditions associated with significant changes in plasma corticosterone concentration. Experiments are underway to decipher the cytokine and chemokine responses to vaccination and bacterial challenge on the background of stress-induced immunosuppression.

Through a group process designed for subjective probability assessment, an international panel of fish health experts identified and weighted risk factors perceived important to the emergence and spread of the viral genotype, VHSV IVb, within and from the Great Lakes region of the US and Canada. Identified factors included the presence of known VHSV-susceptible species, water temperatures conducive for disease, hydrologic connectivity and proximity to known VHSV-positive areas, untested shipments of live or frozen fish from known positive regions, insufficient regulatory infrastructure for fish health oversight, and uncontrolled exposure to fomites associated with boat and equipment or fish wastes from known VHSV-positive areas. Results provide qualitative insights for use in VHSV surveillance and risk-management planning, and quantitative estimates of contextual risk for use in a Bayesian model combining multiple evidence streams for joint probability assessment of disease freedom status. Consistency checks suggest that the compiled factors positively reflect expert judgment of watershed risk for acquiring VHSV IVb.

Waterways provide a relatively unconstrained pathway for the spread of VHSV; and structured surveillance for emerging disease in open systems has many challenges. We introduce a decision framework for estimating VHSV infection probability that draws from multiple evidence streams and addresses challenges associated with the assessment of emerging disease. Using this approach, historical and risk-based evidence, whether empirical or expert-derived, supplement surveillance data to estimate disease probability. Surveillance-based estimates of VHSV prevalence were described using beta distributions. Subjective likelihood ratios (LRs), representing contextual risk, were elicited by asking experts to estimate the predicted occurrence of risk factors among VHSV-affected vs. VHSV-unaffected watersheds. We used the odds form of Bayes' theorem to aggregate expert and surveillance evidence to predict the risk-adjusted posterior probability of VHSV-infection for given watersheds. We also used LRs representing contextual risk to quantify the time value of past surveillance data. This evidence aggregation model predicts disease probability from the combined assessment of multiple sources of information. The method also provides a flexible framework for iterative revision of disease freedom status as knowledge and data evolve. Published by Elsevier B.V.

Infectious prions accumulate in brain through a template-mediated conformational conversion of endogenous PrPC into alternately folded PrPSc. Immunoassays toward pre-clinical detection of infectious PrPSc have been confounded by low-level prion accumulation in non-neuronal tissue and the lack of PrPSc selective antibodies. We report a method to purify infectious PrPSc from biological tissues for use as an immunogen and sample enrichment for increased immunoassay sensitivity. Significant prion enrichment is accomplished by sucrose gradient centrifugation of infected tissue and isolation with detergent resistant membranes from lipid rafts (DRMs). At equivalent protein concentration a 50-fold increase in detectable PrPSc was observed in DRM fractions relative to crude brain by direct ELISA. Sequential purification steps result in increased specific infectivity (DRM >20-fold and purified DRM immunogen >40-fold) relative to 1% crude brain homogenate. Purification of PrPSc from DRM was accomplished using phosphotungstic acid protein precipitation after proteinase-K (PK) digestion followed by size exclusion chromatography to separate PK and residual protein fragments from larger prion aggregates. Immunization with purified PrPSc antigen was performed using wild-type (wt) and Prnp(0/0) mice, both on Balb/cJ background. A robust immune response against PrPSc was observed in all inoculated Prnp(0/0) mice resulting in antisera containing high-titer antibodies against prion protein. Antisera from these mice recognized both PrPC and PrPSc, while binding to other brain-derived protein was not observed. In contrast, the PrPSc inoculum was non-immunogenic in wt mice and antisera showed no reactivity with PrP or any other protein.

To help with the identification of E. dodecella, morphological, biological, and molecular evidence are presented. Key features of the adult, larval, and pupal morphology are compared to other species of Exoteleia and illustrated with line drawings or scanning electron micrographs. The high sequence divergence (>7%) of E. dodecella compared to samples of related native North American species demonstrates that DNA barcodes are a useful identification tool for this pest. A summary of the biology of E. dodecella, including 12 species of larval and pupal parasitoids (most representing new host records), is also included.

Leluthia astigma is reported as a parasitoid of Agrilus planipennis Fairmaire, emerald ash borer (EAB), infesting Fraxinus americana L., white ash, in Delaware County, Ohio. It is the first species of Leluthia for which a determined species of Agrilus Curtis has been confirmed as a host and the association vouchered. All other hosts reported in the literature for L. astigma require confirmation through rearing from an isolated host or documentation of an unequivocal host-parasitoid association. Leluthia astigma adults reared from parasitoid cocoons collected in Delaware County, Ohio parasitized and produced F(1) adults in the laboratory on last-instar EAB larvae collected in County, Michigan.

Documentation of progress of this restoration effort is needed. A study was conducted to examine water quality in the Choptank River estuary, a tributary of the Chesapeake Bay that since 1998 has been classified as impaired waters under the Federal Clean Water Act. Multiple water quality parameters (salinity, temperature, dissolved oxygen, chlorophyll a) and analyte concentrations (nutrients, herbicide and herbicide degradation products, arsenic, and copper) were measured at seven sampling stations in the Choptank River estuary. Samples were collected under base flow conditions in the basin on thirteen dates between March 2005 and April 2008. As commonly observed, results indicate that agriculture is a primary source of nitrate in the estuary and that both agriculture and wastewater treatment plants are important sources of phosphorus. Concentrations of copper in the lower estuary consistently exceeded both chronic and acute water quality criteria, possibly due to use of copper in antifouling boat paint. Concentrations of copper in the upstream watersheds were low, indicating that agriculture is not a significant source of copper loading to the estuary. Concentrations of herbicides (atrazine, simazine, and metolachlor) peaked during early-summer, indicating a rapid surface-transport delivery pathway from agricultural areas, while their degradation products (CAT, CEAT, MESA, and MOA) appeared to be delivered via groundwater transport. Some in-river processing of CEAT occurred, whereas MESA was conservative. Observed concentrations of herbicide residues did not approach established levels of concern for aquatic organisms. Results of this study highlight the importance of continued implementation of best management practices to improve water quality in the estuary. This work provides a baseline against which to compare future changes in water quality and may be used to design future monitoring programs needed to assess restoration strategy efficacy.

TI Bacterial diversity in cucumber (Cucumis sativus) rhizosphere in response to salinity, soil pH, and boron SO SOIL BIOLOGY & BIOCHEMISTRY LA English DT Article DE Salinity; Environmental stress; Rhizosphere; pH; Boron; Bacteria ID SAN-JOAQUIN VALLEY; SODIUM-CHLORIDE; GROWTH; WHEAT; WATER; STRESS; IRRIGATION; TOXICITY; YIELD; SALT AB Soil salinity is a major factor relating microbial communities to environmental stress in the microbial selection process as stress can reduce bacterial diversity. In the San Joaquin Valley (SJV) of California, the problem of increasing salinity and consequently, decreasing crop productivity, due to reuse of saline drainage water are major concerns. An experiment was conducted in a closed, recirculating volumetric lysimeter system (VLS) consisting of 24 experimental plant growth units to determine the interactive effects of salinity, boron and pH on rhizosphere and non-rhizosphere microbial composition of cucumber (Cucumis sativus L cv. Seminis Turbo hybrid). Plants in the VLS were irrigated from individual reservoirs containing a modified half-strength Hoagland's nutrient solution combined with salinity, boron (B), and pH treatments. The results indicated that salinity and pH were the most influential factors affecting the growth of plants and the effect of boron on the plant was more severe under slightly acidic conditions. Total bacterial DNA was extracted from rhizosphere and non-rhizosphere samples, and a 236-bp DNA fragment in the V3 region of the small subunit ribosomal RNA genes of eubacteria was amplified. The 16S rRNA and the products were subjected to denaturing gradient gel electrophoresis (DGGE) and sequencing. Analyses of bacterial diversity showed that the effects of salinity, boron, and pH were more severe on the rhizosphere bacterial population during the first week of growing cucumber, with decreasing impacts with plant growth. However, there was no salinity-B-pH interaction effects on plant biomass, but the effects were seen in the number of heterotrophic bacteria in the rhizosphere and on species richness and diversity during week seven of the study. These suggest that the effects of salinity-B-pH interactions may influence microorganisms first before plants and may pose long term effects on soil quality. Published by Elsevier Ltd. C1 [Ibekwe, A.

TI Phosphorus Distribution in Sequentially Extracted Fractions of Biosolids, Poultry Litter, and Granulated Products SO SOIL SCIENCE LA English DT Article DE Biosolids; granulated fertilizer; organic phosphorus; phosphorus forms; poultry litter; sequential fractionation ID SOIL-PHOSPHORUS; ENZYMATIC-HYDROLYSIS; SWINE MANURE; LABORATORY CHARACTERIZATION; HEDLEY FRACTIONATION; ORGANIC PHOSPHORUS; DAIRY MANURE; RUNOFF; PHOSPHATES; DYNAMICS AB Land application of biosolids and poultry litter can benefit crop production by providing phosphorus (P) and other nutrients and organic matter. However, the bioavailability of applied P in those waste materials is directly dependent on the presence of specific P forms. In this study, we comparatively examined the P forms in biosolids and broiler litter by sequential fractionation (i.e., H(2)O, 0.5 M NaHCO(3), 0.1 M NaOH, and 1 M HCl fractions) coupled with enzymatic hydrolysis. Extractable P in broiler litter was found in the order of HCl > H(2)O > NaOH > NaHCO(3). Biosolid P was found in the four fractions in the following order: HCl > NaOH > NaHCO(3) > H(2)O. Correlation analysis indicated that P was coextracted with Ca, Mn, Zn, Fe, and Al, but not Mg. Whereas most P was Ca bound in broiler litter, Al, Mn, and Zn played more important roles in metal P species in biosolids. The relative abundance of P species was determined to be inorganic P > hydrolyzable organic P > nonhydrolyzable organic P in each fraction. Compared with the P levels in the samples stored in a freezer, storage of the broiler litter sample at room temperature transformed part of the phytate P in the HCl fraction to other forms, resulting in more labile P in the H(2)O fraction. Granulated products of poultry litter and biosolid could be used as off-farm nutrient sources. Data in this work show that granulation transformed moderate NaHCO(3)- and NaOH-extractable P bilaterally to labile water-soluble P and stable HCl-extractable P in the granulated poultry litter but did not remarkably change the distribution of H(2)O-, NaHCO(3)-, and NaOH-extractable P in granulated products containing both poultry litter and biosolids.

The objectives were to investigate, in laboratory experiments, the effect of gypsum on the solubility of 13 nutrients and how amending the soil with organic peat moss may mitigate the impact of gypsum on nutrients and soil fertility. A 100-g sample of gypsum-free soil (Sharpsburg Fine, montmorillonitic, mesic Typic Argiudolls) was treated with increasing amounts of gypsum (0, 1, 5, 10, 15, 20, 30, and 50 g), then water was added to the mixtures to reach 50% of the water saturation capacity. Another set of soil/gypsum mixtures received 5-g peat to study the effect of peat application. All mixtures were incubated at 32 degrees C for 15 weeks. After incubation, the concentration of water-soluble nutrients was measured. In general, the addition of gypsum increased the solubility of N, K, Ca, Mg, Mn, Cl, and S, whereas it decreased the solubility of P, Na, Fe, Cu, Zn, and B. The application of peat increased the solubility of all nutrients investigated, except for N and S. Chemical reactions and mechanisms were applied to interpret the effects of both gypsum and peat treatments on nutrient solubility and their relationship to soil fertility and crop production. The application of peat improved the solubility of most nutrients and proved to be useful as an amendment for gypsum-rich soils and increases its productivity.

TI Germination and Early Growth of Slickspot Peppergrass (Lepidium papilliferum) as Affected by Desert Soil Humic Acids SO SOIL SCIENCE LA English DT Article DE Slickspot peppergrass; soil humic acids; germination; early growth ID BRASSICACEAE AB Slickspot peppergrass (Lepidium papilliferum) is a biennial, or possibly perennial, endemic plant growing in the Southern Idaho high desert in visually distinct small-scale depressions in soils that collect water (so-called slickspots). Lepidium papilliferum establishes seed banks not germinating the first year but remaining dormant and viable for several years. Humic acids (HA) are universally considered to be the most important, abundant, and biologically and chemically active fractions of soil organic matter and are known to affect plant growth by various mechanisms, depending on their origin, nature, and concentration. The effects of HA in slickspot soils and how they relate to the possibility of being a factor in restoring native plants is only partially known. Thus, the objective of this study was to identify and evaluate the effects of HA isolated from three different layers within the soil pro. le (silt, vesicular, and clay) from inside a representative slickspot on the germination and early growth of slickspot peppergrass. Furthermore, these effects were tentatively related to the chemical, physicochemical, compositional, structural, and functional characteristics of the HA. Results of statistical analysis showed that both the type and concentration of the three HA examined exert a highly significant or significant effect on the germination and early growth of slickspot peppergrass as a function of the soil depth from which the HA originated in the slickspot. In particular, germination seemed to be enhanced, especially at higher concentrations, by the less hydrophobic HA, rich in oxygen and total sugars, present in the bottom clay soil layer, whereas root growth and shoot growth were positively influenced by the more hydrophobic and probably more polycondensed HA, rich in C, H, N, and phenolic OH present in the top layer rich in silt.

TI Floral and macroecological evolution within Cyrtanthus (Amaryllidaceae): Inferences from combined analyses of plastid ndhF and nrDNA ITS sequences SO SOUTH AFRICAN JOURNAL OF BOTANY LA English DT Article DE Africa; Amaryllidaceae; Cyrtanthus; Floral morphology; Molecular systematics; Monocotyledons ID FLY POLLINATION SYSTEM; CAPE FLORISTIC REGION; MOLECULAR-DATA SETS; SOUTHERN-AFRICA; DNA-SEQUENCES; RECOMBINATION DETECTION; GENUS CYRTANTHUS; PLANT DIVERSITY; EASTERN CAPE; PHYLOGENY AB One of the most diverse members of Amaryllidaceae is Cyrtanthus Aiton, a large, sub-Saharan Africa genus of approximately 55 species found mostly in South Africa. To investigate phylogenetic and biogeographic relationships within Cyrtanthus, sequence data from the plastid ndhF gene and the ITS nrDNA region for 41 species were analyzed with parsimony, maximum likelihood, and Bayesian-inference approaches. Various recombination detection algorithms were used to test for interspecific hybridization in the ITS alignment. The genus resolved as monophyletic, comprising three poorly to well-supported major lineages: a predominantly Afrotemperate lineage, largely restricted to seasonally moist sites in summer rainfall southern Africa, a subtropical lineage found mostly in nonseasonal rainfall regions, often in dry habitats, and a Cape Floristic Region-centered lineage in which most species are concentrated in the summer-dry to nonseasonal rainfall southwest. The ITS sequence alignment shows no evidence for reticulation between any of the species. Relationships inferred by the molecular data disagree with those derived from morphological data, but agree with previously published groupings based on karyotype morphology. Fitch optimization of selected floral characters on the combined gene tree reveals recurrent patterns of convergence. Ornithophilous floral forms occur in parallel among the three primary clades, putatively sphingophilous species are concentrated in the Afrotemperate lineage in seasonally moist upland grasslands; the brush-type Aeropetes tulbaghia butterfly and inferred long-proboscid fly pollination syndromes are unique in the Cape lineage. Macroecological factors inferred to have influenced the evolution of Cyrtanthus are changes in rainfall seasonality, the advent of fire, and the availability of new habitats at high and low altitudes and in rock-free soils or rock crevices. This study gives greater clarity on relationships within the genus and enables its division into three informal infrageneric groups. (C) 2009 SAAB. Published by Elsevier B.V. All rights reserved.

Spray-drying conditions were controlled by the flow rate of the slurry and inlet temperature. Spray-dried rice flours and unprocessed rice flour were examined for their lipolytic stability during storage for 210 days by measuring free fatty acid (FFA) formation. The percentage of lipid and FFA in rice flour was significantly reduced by spray drying. The resulting amount of lipid and percentage of FFA was rice-type dependent and related to the amylose content and the outlet temperature. Upon storage, the formation of FFA was lowest for rice flours processed at 115 degrees C outlet temperature as compared to 80 degrees C, 50 degrees C, and control (untreated rice flour). Pin milling of the spray-dried flour resulted in the breakdown of loose re-agglomerated rice flour formed during spray drying with a particle size similar to rice starch but increased starch damage by about 1% per pass through pin mill.

The head rice grain composition of 23 U.S. long-grain cultivars was evaluated in terms of apparent amylose content, crude protein, and surface lipids. Starch samples were prepared by extraction with dilute alkali and amylopectin fine structure was characterized by high-performance anion-exchange chromatography with pulsed amperometric detection. Hardness and stickiness of head rice samples cooked in optimum water were measured with a texture analyzer. The amylose amylopectin ratio (AAR) of the material that leached out of the grains on cooking was evaluated by high-performance size-exclusion chromatography (HPSEC). Simple correlation and multivariate linear regression analyses pointed to AAR as the main indicator of cooked rice hardness and stickiness. Cluster analysis showed that the leached starch from soft-cooking, high-amylose cultivars (e.g., Jodon and L-202) generally had a higher proportion of amylopectin than amylose (AAR<1). In contrast, dry-cooking, high-amylose cultivars (e.g., Newrex and L-205) leached out starch with a higher proportion of amylose than amylopectin (AAR>1) during cooking. The amount of leached materials itself was also higher for the soft-cooking cultivars than the dry-cooking counterparts. Cultivar differences in leaching characteristics were attributed to variations in apparent amylose content, crude protein, and amylopectin chain-length distribution.

In reciprocal DNA/DNA hybridization experiments. DNA relatedness was high (69-100%) between P. syringae pv. alisalensis strains and the type strain of P. cannabina (genomospecies 9). In contrast, DNA relatedness was low (below 48%) between P. syringae pv. alisalensis and reference strains from the remaining genomospecies of P. syringae including the type strain of P. syringae and reference strain of genomospecies 3 (P. syringae pv. tomato) although the well-known crucifer pathogen, P. syringae pv. maculicola, also belongs to genomospecies 3. Additional evidence that P. syringae pv. alisalensis belongs to P. cannabina was sequence similarity in five gene fragments used in multilocus sequence typing, as well as similar rep-PCR patterns when using the BOX-A1R primers. The description of P. cannabina has been emended to include P. syringae pv. alisalensis. Host range testing demonstrated that P. syringae pv. alisalensis strains, originally isolated from broccoli, broccoli raab or arugula, were not pathogenic on Cannabis sativa (family Cannabinaceae). Additionally, P. cannabina strains, originally isolated from the C. sativa were not pathogenic on broccoli raab or oat while P. syringae pv. alisalensis strains were pathogenic on these hosts. Distinct host ranges for these two groups indicate that P. cannabina emend, consists of at least two distinct pathovars, P. cannabina pv. cannabina pv. nov., and P. cannabina pv. alisalensis comb. nov.

Concerning surface types, the greatest underestimations occur in farmland and forest ecosystems. The largest and smallest biases are seen in spring and in summer, respectively. The systematic underestimation seems to stem from the use of too high single scattering albedos similar to 0.96 which is significantly higher than those estimated from ground-based observations. Further improvements to the MISR aerosol algorithm, especially in the aerosol model, are recommended.

TI Soybean seed lipoxygenase genes: molecular characterization and development of molecular marker assays SO THEORETICAL AND APPLIED GENETICS LA English DT Article ID GLYCINE-MAX; SUBCELLULAR-LOCALIZATION; NULL-ALLELE; ISOZYMES; INHERITANCE; CATALYSIS; LACKING AB Soybean seeds contain three lipoxygenase (Lox) enzymes that are controlled by separate genes, Lox1, Lox2 and Lox3. Lipoxygenases play a role in the development of unpleasant flavors in foods containing soybean by oxidation of polyunsaturated fatty acids. Null alleles for all three enzymes have been identified, lox1, lox2 and lox3, and are known to be inherited as simple recessive alleles. Previous studies determined that a missense mutation rendered Lox2 inactive; however, the genetic cause of either lox1 or lox3 mutation was not known. The objectives of this study were the molecular characterization of both lox1 and lox3 mutant alleles and the development of molecular markers to accelerate breeding for Lox-free soybean varieties. We identified two independent mutant alleles as the genetic causes of the lack of Lox1 in seeds of two lox1 mutant soybean lines. Similarly, a mutant allele that truncates Lox3 in a lox3 mutant soybean line was identified. Molecular markers were designed and confirmed to distinguish mutant, wild type, and heterozygous individuals for Lox1, Lox2 and Lox3 genes. Genotype and Lox phenotype analysis showed a perfect association between the inheritance of homozygous lox mutant alleles and the lack of Lox activity. Molecular characterization of a seed-lipoxygenase-free soybean line led to the discovery that an induced recombination event within the Lox1 gene was responsible for breaking the tight linkage in repulsion phase between mutant alleles at the Lox1 and Lox2 loci. The molecular resources developed in this work should accelerate the inclusion of the lipoxygenase-free trait in soybean varieties.

TI Genetic dissection of chromosome substitution lines of cotton to discover novel Gossypium barbadense L. alleles for improvement of agronomic traits SO THEORETICAL AND APPLIED GENETICS LA English DT Article ID UPLAND COTTON; FIBER QUALITY; VARIANCE-COMPONENTS; GERMPLASM LINES; QTL ANALYSIS; HIRSUTUM L; CULTIVARS; GENOME; RECOMBINATION; INTROGRESSION AB We recently released a set of 17 chromosome substitution (CS-B) lines (2n = 52) that contain Gossypium barbadense L. doubled-haploid line '3-79' germplasm systematically introgressed into the Upland inbred 'TM-1' of G. hirsutum (L.). TM-1 yields much more than 3-79, but cotton from the latter has superior fiber properties. To explore the use of these quasi-isogenic lines in studying gene interactions, we created a partial diallel among six CS-B lines and the inbred TM-1, and characterized their descendents for lint percentage, boll weight, seedcotton yield and lint yield across four environments. Phenotypic data on the traits were analyzed according to the ADAA genetic model to detect significant additive, dominance, and additive-by-additive epistasis effects at the chromosome and chromosome-by-chromosome levels of CS-B lines. For example, line 3-79 had the lowest boll weight, seedcotton yield and lint yield, but CS-B22Lo homozygous dominance genetic effects on seedcotton and lint yield were nearly four times those of TM-1, and its hybrids with TM-1 had the highest additive-by-additive epistatic effects on seedcotton and lint yield. CS-B14sh, 17, 22Lo and 25 produced positive homozygous dominance effects on lint yield, whereas doubly heterozygous combinations of CS-B14sh with CS-B17, 22Lo and 25 produced negative dominance effects, suggesting that epistatic effects between genes in these chromosomes strongly affect lint yield. The results underscore the opportunities to systematically identify genomic regions harboring genes that impart agronomically significant effects via epistatic interactions. The chromosome-by-chromosome approach significantly complements other strategies to detect and quantify epistatic interaction effects, and the quasi-isogenic nature of families and lines from CS-B intermatings will facilitate high-resolution localization, development of markers for selection and map-assisted identification of genes involved in strong epistatic effects.

TI Role of the Osmotic Stress Regulatory Pathway in Morphogenesis and Secondary Metabolism in Filamentous Fungi SO TOXINS LA English DT Review DE Aspergillus; osmotic stress; regulation; morphogenesis; secondary metabolism AB Environmental stimuli trigger an adaptative cellular response to optimize the probability of survival and proliferation. In eukaryotic organisms from mammals to fungi osmotic stress, mainly through the action of the high osmolarity glycerol (HOG) pathway, leads to a response necessary for adapting and surviving hyperosmotic environments. In this review we show that the osmoadaptative response is conserved but not identical in different fungi. The osmoadaptative response system is also intimately linked to morphogenesis in filamentous fungi, including mycotoxin producers. Previous studies indicate that the response to osmotic stress is also coupled to the biosynthesis of natural products, including mycotoxins.

Molecular methods have revealed more than 18 cryptic species, of which several have been characterized as potential mycotoxin producers. Others are defined as benign relative to their ability to produce mycotoxins. However, these characterizations are based on in vitro culture and toxins production. Several can produce the ochratoxins that are toxic to livestock, poultry, and humans. The black aspergilli produce rots of grapes, maize, and numerous other fruits and grain and they are generally viewed as post-harvest pathogens. Data are review to suggest that black aspergilli, as so many others, are symptomless endophytes. These fungi and their mycotoxins contaminate several major grains, foodstuffs, and products made from them such as wine, and coffee. Evidence is presented that the black aspergilli are producers of other classes of mycotoxins such as the fumonisins, which are known carcinogenic and known prior investigations as being produced by the Fusarium species. Three species are identified in U.S. maize and peanuts as symptomless endophytes, which suggests the potential for concern as pathogens and as food safety hazards.

However, to derive commercial benefit from this resistance and develop lines that can aid growers, markers need to be identified to facilitate the transfer of resistance into commercially useful genetic backgrounds without transfer of unwanted traits. To accomplish this, research efforts have focused on the identification of kernel resistance-associated proteins (RAPs) including the employment of comparative proteomics to investigate closely-related maize lines that vary in aflatoxin accumulation. RAPs have been identified and several further characterized through physiological and biochemical investigations to determine their causal role in resistance and, therefore, their suitability as breeding markers. Three RAPs, a 14 kDa trypsin inhibitor, pathogenesis-related protein 10 and glyoxalase I are being investigated using RNAi gene silencing and plant transformation. Several resistant lines have been subjected to QTL mapping to identify loci associated with the aflatoxin-resistance phenotype. Results of proteome and characterization studies are discussed.

In most cases, antibiotic or herbicide resistance marker genes are preferred because they tend to be most efficient. Due mainly to consumer and grower concerns, considerable effort is being put into developing strategies (site-specific recombination, homologous recombination, transposition, and cotransformation) to eliminate the marker gene from the nuclear or chloroplast genome after selection. For the commercialization of genetically transformed plants, use of a completely marker-free technology would be desirable, since there would be no involvement of antibiotic resistance genes or other marker genes with negative connotations for the public. With this goal in mind, a technique for apple transformation was developed without use of any selectable marker. Transformation of the apple genotype "M.26" with the constructs pPin2Att35SGUSintron and pPin2MpNPR1 was achieved. In different experiments, 22.0-25.4% of regenerants showed integration of the gene of interest. Southern analysis in some transformed lines confirmed the integration of one copy of the gene. Some of these transformed lines have been propagated and used to determine the uniformity of transformed tissues in the plantlets. The majority of the lines are uniformly transformed plants, although some lines are chimeric, as also occurs with the conventional transformation procedure using a selectable marker gene. A second genotype of apple, "Galaxy," was also transformed with the same constructs, with a transformation efficiency of 13%.

Recent developments identify three strategies that make optimal use of current understanding in an environment of inevitable uncertainty and abrupt change: reducing the magnitude of, and exposure and sensitivity to, known stresses; focusing on proactive policies that shape change; and avoiding or escaping unsustainable social ecological traps. As we discuss here, all social ecological systems are vulnerable to recent and projected changes but have sources of adaptive capacity and resilience that can sustain ecosystem services and human well-being through active ecosystem stewardship.

Cats are the only definitive host and thus the only source of infective oocysts, but other mammals and birds can develop tissue cysts. Although feline infections are typically asymptomatic, infection during human pregnancy can cause severe disease in the fetus. Cat owners can reduce their pets' exposure risk by keeping all cats indoors and not feeding them raw meat. Humans usually become infected through ingestion of oocyst-contaminated soil and water, tissue cysts in undercooked meat, or congenitally. Because of their fastidious nature, the passing of non-infective oocysts, and the short duration of oocyst shedding, direct contact with cats is not thought to be a primary risk for human infection.

The sterile insect technique and similar methods control certain agricultural insect pest populations in a species-specific, environmentally sound, and effective manner; there is increased interest in applying this approach to vector control. Such an approach, like all others in use and development, is not a one-size-fits-all solution, and will be more appropriate in some situations than others. In addition, the proposed release of pest insects, and more so genetically modified pest insects, is bound to raise questions in the general public and the scientific community as to such a method's efficacy, safety, and sustainability. This article attempts to address these concerns and indicate where sterile-insect methods are likely to be useful for vector control. C1 [Alphey, Luke] Oxitec Ltd, Oxford OX14 4RX, England.

TI Interleukin-8, Interleukin-1 beta, and Interferon-gamma Levels Are Linked to PRRS Virus Clearance SO VIRAL IMMUNOLOGY LA English DT Article ID RESPIRATORY-SYNDROME-VIRUS; PROINFLAMMATORY CYTOKINES; MYCOPLASMA-HYOPNEUMONIAE; EXPERIMENTAL-INFECTION; REPRODUCTIVE FAILURE; PERSISTENT INFECTION; IMMUNE-RESPONSE; IN-UTERO; PIGS; EXPRESSION AB Infection with porcine reproductive and respiratory syndrome virus (PRRSV) results in a weak antiviral immune response that leads to a persistent infection in a subset of pigs. We investigated the intensity and timing of the early cytokine responses to PRRSV infection to determine their utility as a predictor of persistence. As part of the "Big Pig'' project, we evaluated cytokine gene expression in lymphoid tissues collected from pigs for up 202 days post-infection (dpi); serum samples were collected biweekly. Cytokine mRNA levels were compared between pigs that cleared the viral infection from serum and tissues (non-persistent [NP] pigs) to those of persistent (P) pigs, that had viral RNA in their serum for up to 126 dpi. The gene expression studies in the tracheobronchial lymph nodes (TBLN) of all the pigs showed upregulation of interferon-gamma (IFN-gamma)-associated T-helper 1 (Th-1) markers from 14-84 dpi, and of T-regulatory interleukin-10 (IL-10), but no upregulation of innate markers (IFN-gamma, IL-1 beta, and IL-8). At later time points (>112 dpi) these genes were no longer differentially expressed and thus were uninformative for persistence studies. Statistical analyses of serum cytokine levels indicated that innate cytokine (IL-1 beta and IL-8) levels were upregulated early after infection. Interestingly, serum IL-8 levels in NP pigs were significantly higher than in P pigs at 14 dpi. When analyzed together, variations in all three of the serum cytokines tested (IL-8, IL-1 beta, and IFN-gamma) was significantly correlated with virus level, accounting for similar to 84% of the variations observed. These results indicate that while each cytokine individually has minor effects on the length of virus replication, the combination of cytokine activities should be considered when understanding the role of immunity in persistence.

The genome of an Argentinean isolate of Solenopsis invicta virus 3 (SINV-3(ArgSF) ) obtained from the Santa Fe region of Argentina was sequenced in entirety. Assembly of nine overlapping fragments yielded a consensus genome sequence 10,386 nucleotides long, excluding the poly(A) tail present on the 3' end (Genbank accession number GU017972). With the exception of the poly(A) tail, the genome length of SINV-3(ArgSF) was identical to the North American isolate (SINV-3(USDM) ). The SINV-3(ArgSF) genome possessed three major open reading frames (ORFs) (comprised of a parts per thousand yen100 codons) in the sense orientation; SINV-3(USDM) possessed only two. ORFs 1 and 2 had identical start and stop genome positions for both isolates. Blastp analysis of the translated ORF 1 of SINV-3(ArgSF) recognized conserved domains for helicase, protease, and RNA-dependent RNA polymerase. These domains and their corresponding positions were identical to those reported for SINV-3(USDM) . ORF 2a, unique to the SINV-3(ArgSF) genome, was also found in frame 2 and had a canonical start codon located at nucleotide position 8,351 and a stop codon ending at position 8,827. Blastp analysis of the translated amino acid sequence of ORF 2a revealed no significant similarity in the Genbank database. The two SINV-3 isolates exhibited 96.2% nucleotide sequence identity across the entire genome. The amino acid sequences of ORFs 1 and 2 exhibited higher identities (99.0 and 98.2%, respectively) than the corresponding nucleotide regions within the genome. These data indicated that the nucleotide differences between the SINV-3 isolates were largely synonymous. This observation was corroborated by codon substitution rate analysis. Thus, the majority of the SINV-3 codon changes were silent in the two polyproteins, indicating purifying selection pressure on the viral genome.

Canada thistle plants were grown from root cuttings and treated in the rosette growth stage. The effect of different adjuvants on absorption was determined by treating individual leaves with formulated herbicide plus (14)C-herbicide alone or with methylated seed oil (MSO), crop oil concentrate, or nonionic surfactant with and without urea ammonium nitrate and ammonium sulfate. Plants were harvested 96 h after treatment (HAT). For absorption and translocation experiments, plants were oversprayed with aminocyclopyrachlor or its methyl ester at a rate of 0.14 kg ae ha(-1) in combination with 1% MSO. Formulated herbicide plus (14)C-herbicide was then applied to a protected leaf, and plants were harvested 24 to 192 HAT. Plants were harvested and radioactivity was determined in the treated leaf and in aboveground and belowground tissues. Metabolism of aminocyclopyrachlor-methyl ester to the free acid was determined 2, 6, and 24 HAT. All aboveground biomass was analyzed by high-performance liquid chromatography to establish the ratio of methyl ester to free acid. MSO applied with either herbicide formulation resulted in the highest absorption compared with no surfactant. Significantly greater aminocyclopyrachlor-methyl ester was absorbed, compared with the free acid, which was reflected in the greater aboveground translocation for the methyl ester. Both formulations had similar amounts of translocation to the roots, with 8.6% (SE +/- 3.3) for the methyl ester compared with 6.2% (SE +/- 2.5) for the free acid. Approximately 80% of the methyl ester was converted to the free acid at 6 HAT. Based on this conversion rate, aminocyclopyrachlor translocated as the free acid in Canada thistle. C1 [Lindenmayer, R.

The potential volatility of this new herbicide and its methyl ester were determined under laboratory conditions and were also compared to dicamba and aminopyralid with the use of enclosed chamber and open-air plant bioassay's. Bioassays consisting of visual estimates of epinastic responses and kidney bean and soybean leaf-width measurements were developed to measure vapor release from glass and plastic. Vapor release of aminocyclopyrachlor from glass surfaces was undetectable under laboratory conditions, and no phytotoxic responses were observed when plants were exposed to vapors emanating from various surfaces. Results were similar to those of aminopyralid, indicating the risk of plant injury from vapor movement of aminocyclopyrachlor and aminopyralid was very low. When combined with 1% methylated seed oil, vapor release of aminocyclopyrachlor-methyl ester reached 86% 192 h after application to glass surfaces. Phytotoxic responses of plants exposed to vapors emanating from various surfaces treated with aminocyclopyrachlor-methyl ester were similar to responses to dicamba under enclosed incubation conditions, but were less in outdoor, open-air environments. Studies are needed to understand better the risk of injury to nontarget plants due to vapor movement of aminocyclopyrachlor-methyl ester under field applications.

CRONQ.; CROPS; TRANSLOCATION; ARABIDOPSIS; RETENTION AB The evolution of glyphosate resistance in weedy species places an environmentally benign herbicide in peril. The first report of a dicot plant with evolved glyphosate resistance was horseweed, which occurred in 2001. Since then, several species have evolved glyphosate resistance and genomic information about nontarget resistance mechanisms in any of them ranges from none to little. Here, we report a study combining iGentifier transcriptome analysis, cDNA sequencing, and a heterologous microarray analysis to explore potential molecular and transcriptomic mechanisms of nontarget glyphosate resistance of horseweed. The results indicate that similar molecular mechanisms might exist for nontarget herbicide resistance across multiple resistant plants from different locations, even though resistance among these resistant plants likely evolved independently and available evidence suggests resistance has evolved at least four separate times. In addition, both the microarray and sequence analyses identified non target-site resistance candidate genes for follow-on functional genomics analysis. C1 [Abercrombie, Laura L.

When grown alone, in pots, the GR horseweeds consistently developed more rapidly than the GS weeds, as evidenced by their earlier bolting, flowering, and seed set; the GR horseweeds set seeds nearly 25 d (approximately 190 fewer growing degree clays) sooner than the GS horseweed. At seed set, the relatively slow-developing GS horseweeds had amassed 40% more shoot dry matter than the GR weeds at the same phenological stage, but neither biotype was consistently more fecund than the other. Although the GR biotype had lower shoot dry mass than the GS biotype when grown alone, in mixed populations under increasing levels of competition (in a replacement series design) and limited resources (mainly moisture), the GR weeds were not only taller, but also accumulated more dry matter than the GS weeds. Thus, the GR biotype was more competitive than the GS biotype, particularly when grown at high densities and under moisture-deficit stress. Therefore, under California conditions there is no apparent fitness penalty for this particular GR horseweed biotype, and it is likely to persist in the environment and outcompete the GS biotypes regardless of further glyphosate selection pressure. If so, this biotype of GR horseweed is likely to become increasingly common in the SJV until effective management strategies are developed and adopted.

The experiment was conducted in a split split plot arrangement of treatments in a randomized complete block design with row pattern as the main plot, cultivars as the subplot, and herbicide programs as the subsubplot. Cotton canopy closed 2 wk earlier in the twin-row pattern compared to the single-row pattern. Canopy closure was unaffected by cultivars and herbicide programs. Control of nine predominant weeds was sufficient (>= 95%) to support cotton production. Total weed dry biomass was reduced by 35% in twin rows compared to the single-row pattern, 15% in DP117B2RF compared to DP164B2RF cultivar, and >= 97% with glyphosate early POST (EPOST), EPOST followed by (fb) mid-season POST (MPOST), EPOST fb MPOST fb late POST (LPOST) following PRE herbicides or three applications of glyphosate POST only without PRE herbicides compared to no herbicide. Cotton grown in twin-row pattern produced 6% higher lint yield than single-row cotton. Cultivar DP117B2RF produced 23% higher lint yield than cultivar DP164B2RF. Lint yields were higher with glyphosate EPOST fb MPOST, [POST fb MPOST fb LPOST following PRE herbicides or three applications of glyphosate POST only without PRE herbicides (1,210 to 1,230 kg/ha) compared to glyphosate [POST following PRE herbicides (1,130 kg/ha). These results demonstrated that cotton grown in twin-rows closed canopy early and produced higher lint yields than cotton grown in single-rows.

TI Significance of Atrazine in Sweet Corn Weed Management Systems SO WEED TECHNOLOGY LA English DT Article DE Economics; integrated weed management; reduced rate; regulatory; survey ID MESOTRIONE AB Weed management systems used by sweet corn growers, including the role of atrazine, are poorly characterized. Management records of 175 fields throughout the major sweet corn production areas of the Midwest were surveyed from 2005 to 2007. Seventy-four percent of sweet corn fields in the Midwest were grown in rotation with soybean or corn. Interrow cultivation was used on 48% of fields, and atrazine use was higher in those fields without interrow cultivation. A majority of fields (54%) received both PRE and POST herbicide applications. Mesotrione was applied below the registered use rate in two-thirds of the fields in which it was used POST. Atrazine rates in sweet corn were highest when the preceding crops were other vegetables, compared to preceding crops of soybean or corn. Selective herbicides are used extensively in U.S. sweet corn production, accounting for 94% of total weed management expenditures which average $123/ha. Growers treated 66% of fields with one or more applications of atrazine at an average total use rate of 1.35 kg ai/ha. The estimated annual net cost to replace atrazine in U.S. sweet corn production with the broad spectrum broadleaf herbicide, mesotrione, is $9.2 million.

Main plots were three levels of soil pH: maintained at a natural pH level, pH raised with Ca(OH)(2), and pH lowered with Al-2(SO4)(3). Subplots were a factorial arrangement of two halosulfuron application methods and three halosulfuron rates. Halosulfuron application methods were PPI or POST after transplanting to the edges of mulch-covered seedbeds. Halosulfuron rates were 35 and 70 g ai/ha, along with a nontreated control. Cantaloupe were transplanted, maintained weed-free, and evaluated for yield response. After cantaloupe harvest, direct-seeded turnip green and transplanted cabbage were established in September of each year and evaluated for crop tolerance and yield. Data indicated nonsignificant main effects of soil pH and halosulfuron application method on cantaloupe yield. However, in 2007 cantaloupe yields were significantly reduced, by 16 and 20% for halosulfuron applied at 35 and 70 g/ha, respectively. For all turnip green and cabbage response parameters, interactions were nonsignificant between application method and rate, soil pH and rate, and soil pH and application method, along with the three-way interaction. After 6 mo, there was no evidence of stunting from halosulfuron carryover in 2006 to direct-seeded turnip green and in both years to transplanted cabbage. Visual estimates of stunting to direct-seeded turnip green ranged from 9 to 16% for halosulfuron at 35 and 70 g/ha, respectively, in 2007, but all stunting was transient and turnip green yield was not affected.

Although regarded as a catastrophic event, the Jasper Fire left a mosaic of fire severity across the landscape, with live trees present in areas burned under low and moderate fire severity. In October 2005, we cored 96 trees from unburned, low-severity, and moderate-severity stands and assessed whether tree growth differed among fire severity classes during the 5 years postfire. We observed no differences in basal area increment (BAI) 10 years prefire among fire severities with BAI averaging 9.6 cm(2) per year. Despite severe drought conditions, BAI in moderate severity sites 2 years postfire was 58% greater than in unburned and low-severity stands. Although significant, this growth increase was short-lived. Three, 4, and 5 years postfire, no differences in growth among unburned, low-severity, and moderate-severity sites were detected, as BAI averaged 8.3, 7.5, and 7.0 cm(2), respectively. The lack of a consistent and prolonged growth response suggests that the Jasper Fire did not result in any short-term changes in growth patterns. Data extending beyond 5 years postfire are required to infer potential long-term changes in tree growth and productivity.

TI Incorporation of Genetic Gain into Growth Projections of Douglas-Fir Using ORGANON and the Forest Vegetation Simulator SO WESTERN JOURNAL OF APPLIED FORESTRY LA English DT Article DE tree improvement; growth and yield; growth models AB Growth models for coast Douglas-fir (Pseudotsuga menziesii var. menziesii [Mirk] Franco) are generally based on measurements of stands that are genetically unimproved (or woods-run); therefore, they cannot be expected to accurately project the development of stands that originate from improved seedlots. In this report, we demonstrate how early expected gain and genetic-gain multipliers can be incorporated into growth projection, and we also summarize projected volume gains and other aspects of stand development under different levels of genetic gain, site productivity, and initial planting density. Representative tree lists that included three levels of productivity (site index = 100, 125, and 150 ft; base = 50 years) and three initial planting densities (302, 435, and 602 trees/ac) were projected from ages 10 to 60 years under three scenarios using two regional growth models (Stand Management Cooperative version of ORGANON and the Pacific Northwest variant of the Forest Vegetation Simulator). The two models projected similar percentage volume gains for improved seedlots. Seed lots with a genetic worth (GW) of 5% for height and diameter growth were projected to have volume gains of 3.3-5.8% over woods-run stands at 40 years and 2.1-3.2% at 60 years. Volume gains were projected to approximately double when GW was increased from 5 to 10%. C1 [Gould, Peter J.] US Forest Serv, Pacific NW Res Stn, Olympia, WA 98501 USA.

Defect and merchantable volume were assessed by a certified scaler during the first 3 years. A greater proportion of wood volume in small trees was affected by decay, wood borers, and checks than in the large trees.

The study reported in this article was designed to help managers decide whether the common practice of removing the damaged but potentially valuable butt section of the bottom log and leaving it in the woods is warranted. Thirty-four damaged and 28 undamaged trees were selected from three sites in western Washington where bear damage has been a persistent problem. Trees were felled and bucked into 16-ft lengths. The damaged trees in the sample had been injured at ages between 10 and 15 years at two sites and between 10 and 65 years at the third site. The primary scaling deductions were for ring and scar defects. The 16-ft butt logs from the damaged and undamaged trees were sawn into dimension lumber. Bear-damaged logs were found to have lower cubic volume recovery than undamaged logs having the same small-end diameters. Lumber grade recovery was also influenced by bear damage; logs from damaged trees had a lower percentage of high-value lumber. The analysis suggests that the optimal harvesting policy is to haul the entire butt log to the mill rather than leaving the damaged portion in the woods. Although the value of the damaged portion is lower, most of the lumber recovered from that section can be used, with only a modest reduction in grade and value.

There is no experimental evidence, however, demonstrating the efficacy of partial cutting in spruce type. Such experiments are very difficult to complete because of the inability to manipulate bark beetle populations needed to challenge treated stands. To circumvent this difficulty, we identified spruce stands that were partially cut (for nonexperimental reasons) in advance of beetle activity and compared beetle-caused mortality to that in nearby spruce stands that were not treated. Treated stands had fewer infested stems and less infested BA than untreated stands, as well as smaller proportions of infested stems and BA. Untreated stands, however, had more residual spruce stems and BA than treated stands. Most of this difference was among stems 3-11 in. dbh with little difference in survivorship among larger stems. Spruce regeneration was not significantly different among treated and untreated stands. Spruce stand density index, spruce BA, and the number of spruce stems >11 in. dbh were the stand variables most strongly correlated with host mortality measurements. Insect population pressure appears to influence the degree of protection to residual spruce following partial cutting. C1 [Hansen, E. Matthew] US Forest Serv, Rocky Mt Res Stn, Logan, UT 84321 USA.

Squirrel captures were significantly correlated with volume of downed wood and number of snags. Diets were examined from scat collections (n = 40, deciduous/coniferous; n = 10, coniferous). Number of fungal spores in the scat was significantly correlated with number of snags. From each scat collection, the frequencies of plant, animal, fungal, and unidentified components were determined. Hypogeous fungi were a frequent component of the diet, being found in 98.3% and 78.8% of the scat observed in 2005 and 2006. In 2006, as the frequency of dietary fungi decreased, the frequency of plant material increased from <1.0% to 8.0% and frequency of unidentified material increased front 2.0% to 74.0%. Animal content in the scat was negligible (<1.0% to 1.0%). Rhizopogon was the most frequently occurring hypogeous fungus observed. Rhizopogon spores made up 97.9% of the spores counted in 2005 and 96.4% in 2006. Elaphomyces, Gautieria, Geopora, Hymenogaster, and Hysterangium were observed at much lower frequencies. Sporocarps were collected throughout the trapping periods. Fourteen were collected in 2005 and 12 in 2006. Of the 26 sporocarps collected, 11 were Rhizopogon, 4 Elaphomyces, 2 Gautieria, 1 Hymenogaster, 7 Hysterangium, and 1 Tuber This study is the first to examine flying squirrel diets in the Black Hills and the first to report Elaphomyces, Gautieria Hymenogaster; Hysterangium, Rhizopogon, and Tuber sporocarps from the South Dakota Black Hills.

The significance of these sugar sources to insect survival and disease transmission is poorly known. Culicoides sonoreasis, a biting midge, can survive on plant sugars but might also feed on homopteran honeydew. The survival of C. sonorensis fed 10% melezitose or 10% stachyose was compared to that of C. sonorensis fed 10%. sucrose. A significantly greater number of C. sonorensis survived longer when fed melezitose than when fed either stachyose or sucrose. The effect of sugar meals on vector competence was measured using bluetongue and epizootic hemorrhagic disease viruses. There was no significant difference in viral persistence. However, if C. sonorensis feeds on homopteran honeydew in the wild, a larger number of midges could survive to transmit orbiviruses.

(wild celery) and associated algal community components in the lower St. Johns River, Florida. Fifteen centimeter diameter intact plant plugs were collected from the LSJR in March 2001 and transported to mesocosm facilities in Lafayette, Louisiana. A factorial experimental design was used consisting of three salinity levels (1, 8, and 18 ppt), three light levels (0, 50, and 90% shading), and three replicate mesocosms of each for a total of 27 mesocosms. The experiment consisted of a 4-week acclimation period followed by a 5-month treatment period. V. americana responded negatively to increased salinity. Although V. americana survived 8 ppt salinity, growth was limited. At 18 ppt, almost all V. americana aboveground biomass had perished within 10 weeks, but when salinity was lowered back to 1 ppt, approximately 20% of the aboveground biomass recovered within the following 10 weeks. At midtreatment harvest, light did not affect V. americana biomass directly (P = 0.8240), but by final harvest (20 weeks) light affected belowground biomass (P < 0.0014). Both salinity and light affected algal growth. Macroalgae dominated 1 ppt salinity treatments in ambient light, but phytoplankton dominated 8 and 18 ppt salinity treatments in ambient light. Algal communities were greatly inhibited by 90% shading. While salinity directly impacted V. americana growth and survival, light effects were less direct and involved algal community associations.

A fire disturbance module was introduced to FORCARB-ON to simulate the effects of wildfire on C, and some of the model's C pools were re-parameterized using data from Canadian forests. Forest C stocks were estimated using allometric equations that represent the relationships between C and net merchantable volume and forest age based on forest inventory statistics. Other pools were included using results from ecological studies related to forest inventory variables. Data from future forest development projections adopted in approved management plans were used as model input to produce forest C budgets for the province's Crown forest management units. The estimates were extended to other types of managed forests in Ontario: parks, measured fire management zones, and private forest lands. Carbon in HWP was estimated in four categories: wood in use, wood in landfill, wood burned for energy, and C emitted by wood decomposition or burning without energy generation. We projected that the C stocks in Ontario's managed forests and HWP (in use and in landfills) would increase by 465.3 Mt from 2001 to 2100, of which 47.9 Mt is from increases in forest C and 417.4 Mt is from HWP C.

Fuel treatments reduce on-site carbon and also change the fire potential and expected outcome of future wildfires, including their carbon emissions. We simulated effects of fuel treatments on 140 stands representing seven major habitat type groups of the northern Rocky Mountains using the Fire and Fuels Extension to the Forest Vegetation Simulator (FFE-FVS). Changes in forest carbon due to mechanical fuel treatment (thinning from below to reduce ladder fuels) and prescribed fire were explored, as well as changes in expected fire behavior and effects of subsequent wildfire. Results indicated that fuel treatments decreased fire severity and crown fire occurrence and reduced subsequent wildfire emissions, but did not increase post-wildfire carbon stored on-site. Conversely, untreated stands had greater wildfire emissions but stored more carbon. Published by Elsevier B.V.

It has been hypothesized that some tree species may become extirpated as climate change effects may exceed their migration ability. The goal of this study was to compare tree species compositions in northern urban areas to tree compositions in forestland areas in the eastern U.S. as an indicator of the potential for urban trees to facilitate future forest tree species migration. Results indicated that a number of tree species native to eastern U.S. forests of southern latitudes are currently present in northern urban forests. The biomass density (Mg/ha) of urban tree species is typically less than half of forestland densities with the majority of urban tree species found in nearby (<100 km) forestland. Urban tree propagation is often facilitated by humans, whereas the necessary pollinators and agents of tree seed dispersal in forestlands may be lacking regardless of climate change. It is suggested that urban areas may serve divergent, dual roles as both a native tree seed source and refuge for a limited number of forestland tree species, but also a facilitator of non-native tree invasion.

The treatment strategies were evaluated by simulating 10,000 wildfires with random ignition locations and calculating burn probabilities by 0.5 m flame length categories for each 30 m x 30 m pixel in the study area. The burn conditions for the wildfires were chosen to replicate severe fire events based on 97th percentile historic weather conditions. The burn probabilities were used to calculate wildfire risk profiles for each of the 170 residential structures within the urban interface, and to estimate the expected (probabilistic) wildfire mortality of large trees (>53.3 cm) that are a key indicator of stand restoration objectives. Expected wildfire mortality for large trees was calculated by building flame length mortality functions using the Forest Vegetation Simulator, and subsequently applying these functions to the burn probability outputs. Results suggested that treatments on a relatively minor percentage of the landscape (10%) resulted in a roughly 70% reduction in the expected wildfire loss of large trees for the restoration scenario. Treating stands near residential structures resulted in a higher expected loss of large trees, but relatively lower burn probability and flame length within structure buffers. Substantial reduction in burn probability and flame length around structures was also observed in the restoration scenario where fuel treatments were located 5-10 km distant. These findings quantify off-site fuel treatment effects that are not analyzed in previous landscape fuel management studies. The study highlights tradeoffs between ecological management objectives on wildlands and the protection of residential structures in the urban interface. We also advance the application of quantitative risk analysis to the problem of wildfire threat assessment. Published by Elsevier B.V.

TI Midcanopy growth following thinning in young-growth conifer forests on the Olympic Peninsula western Washington SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE Forest structural development; Midcanopy; Western hemlock; Western redcedar; Variable-density thinning ID DOUGLAS-FIR FORESTS; PACIFIC-NORTHWEST FORESTS; OLD-GROWTH; STRUCTURAL DEVELOPMENT; TREE VIGOR; DENSITY; OREGON; STAND; PATTERNS; AREA AB Midcanopy layers are essential structures in "old-growth" forests on the Olympic Peninsula. Little is known about which stand and tree factors influence the ability of midcanopy trees in young-growth forests to respond to release; however, this information is important to managers interested in accelerating development of late-successional structural characteristics. We examined basal area growth response of midcanopy trees following variable-density thinning in an effort to determine the effect of thinning and local environment on the release of western hemlock (Tsuga heterophylla (Raf.) Sarg.) and western redcedar (Thuja plicata ex. D. Don) on the Olympic Peninsula in western Washington. Release was measured as the difference between average annual basal area growth over the 5-year prior to thinning and the 3-to-6 year period following thinning. Results indicate that while growth rates were similar prior to thinning (5.4 cm(2) year(-1) in both thinned and unthinned patches) midcanopy trees retained in a uniformly thinned matrix grew significantly more (8.0 cm(2) year(-1)) than those in unthinned patches (5.4 cm(2) year(-1)) for western hemlock and for western redcedar. Crown fullness and crown crowding affected the release of western hemlock in the thinned matrix. Initial tree size, relative age, local crowding and measures of crown size and vigor affected the release of western redcedar in the thinned matrix. Our results indicate that midcanopy western hemlock and western redcedar retain the ability to respond rapidly with increased growth when overstory competition is reduced and the magnitude of response is related to neighborhood variables (intracohort competition, overstory competition, and tree vigor), thus suggest that variable-density thinning can be an effective tool to create variability in the growth of midcanopy trees in young-growth stands. We expect that this rapid response will produce even greater variability over time. (C) 2010 Elsevier B.V. All rights reserved.

During the early and mid 20th century however, reduced fire frequency allowed fuel to accumulate and hardwoods to increase in the midstory and overstory layers, while woody shrubs gained understory dominance. In 2001, a research study was installed in southern Alabama to develop management options that could be used to reduce fuel loads and restore the ecosystem. As part of a nationwide fire and fire surrogates study, treatments included a control (no fire or other disturbance), prescribed burning only, thinning of selected trees, thinning plus prescribed burning, and herbicide plus prescribed burning. After two cycles of prescribed burning, applied biennially during the growing season, there were positive changes in ecosystem composition. Although thinning treatments produced revenue, while reducing midstory hardwoods and encouraging growth of a grassy understory, burning was needed to discourage regrowth of the hardwood midstory and woody understory. Herbicide application followed by burning gave the quickest changes in understory composition, but repeated applications of fire eventually produced the same results at the end of this 8-year study. Burning was found to be a critical component of any restoration treatment for longleaf communities of this region with positive changes in overstory, midstory and understory layers after just three or four burns applied every 2 or 3 years.

However, information on the efficacy of bacterial inactivation by combined treatments of RFEF and UV-light technologies is limited. In this study, we investigated the relationship between cell injury and inactivation of Escherichia coli K-12 in apple juice treated with a combination of RFEF and UV-light. Apple juice purchased from a wholesale distributor was inoculated with E. con K-12 at 7.8 log CFU/ml, processed with a laboratory scale RFEF unit at 20 kHz, 15 kV/cm for 170 mu s at a flow rate of 540 ml/min followed by UV-light treatment (254 nm) for 12 s at 25, 30 and 40 degrees C Treated samples were analyzed for leakage of UV-substances as a function of membrane damage and were plated (0.1 ml) on Sorbitol MacConkey Agar (SMAC) and Trypticase Soy Agar (TSA) plates to determine the viability loss and percent injury. At 40 degrees C, UV-light treatment alone caused 5.8 log reduction of E coli in apple juice while REEF caused only 2.8 log reduction. A combination of the two processing treatments did not increase cell injury or leakage of intracellular bacterial UV-substances more than that from the UV-light treatment. Similarly, the viability loss determined was not significantly (P<0.05) different than UV-light treatment alone. However, the UV-substances determined in apple juice treated with REEF was significantly (P>0.05) different than UV-light treated samples. The results of this study suggest that RFEF treatment causes more injury to the bacterial cells leading to more leakage of intracellular UV-substances than cells treated with UV-light alone. Also, the effect of the two processing treatment combination on bacterial inactivation was not additive. (C) 2010 Elsevier B.V. All rights reserved.

Pasteurized, preservative-free apple cider was inoculated with E. coli K12 and processed using the SCCO2 system at CO2 concentrations of 0-10% (wa, g CO2/100 g product), outlet temperatures of 34, 38, and 42 degrees C, a system pressure of 7.6 MPa, and a flow rate of 1 L/min. Increased CO2 concentrations and temperatures significantly (P<0.05) enhanced the bactericidal effect, resulting in a maximum reduction of 7.31 log CFU/mL at 8% CO2 and 42 degrees C. A response surface model indicated that minimum CO2 concentrations of 9.9% at 34 degrees C. 7.4% at 38 degrees C, and 5.4% at 42 degrees C are needed to achieve a 5-log reduction of E. coli K12 in apple cider. SEM observations showed morphological changes in the cell envelope after SCCO2 processing. At a processing condition of 8% and 38 degrees C. the reduction of E. coli was 6.03 log and the sublethal injury of the survivors was 84%. The regrowth or survival of E. coli in SCCO2 processed apple cider was not observed during storage for 28 days at 4, 8, and 20 degrees C Thus this study showed the potential of SCCO2 processing with a gas-liquid porous metal contactor for the nonthermal pasteurization of apple cider.

Despite an extensive literature documenting such positive sediment attributes of LWD in forested channels, a quantitative analysis of in-channel sediment storage times associated with channel obstructions has traditionally been difficult to assess. In this study along a 9 km stretch of the Ducktrap River in coastal Maine we present a novel application of fallout cosmogenic Be-7 (t(1/2) = 53 days) coupled with a constant initial activity (CIA) sediment aging model to quantitatively assess transitional bed load storage times in bars associated with in-channel obstructions (LWD and boulders). We find that reach-scale variability in unit stream power and LWD frequency affect sediment storage times, with transport-limited reaches providing longer-term sediment sequestration (generally > 100 days) associated with in-channel obstructions than supply limited ones (<100 days). Estimates of sediment baraccumulation rates also varied between reaches from 0.2 g cm(-2) d(-1) in the supply limited reach to 0.7 g cm(-2) d(-1) in the transport-limited reach. Last, greater frequency of sites, increased sediment volumes and storage times, and naturally viable recruitment mechanisms for LWD in forested channels document its superior ecogeomorphic function when compared to boulders in this study, even in the Ducktrap river, where twentieth century logging has greatly reduced the size, frequency, and geomorphic efficacy of in-channel wood. This study has implications for channel restoration efforts and documents a novel application of 7Be and CIA methodology to constraining transitional bed load storage times in the fluvial environment.

Wohl, Ellen Simon, Andrew TI A comparison of average rates of alluvial erosion between the south-western and south-eastern United States SO EARTH SURFACE PROCESSES AND LANDFORMS LA English DT Article DE incision rates; erosion rates; south-western US; south-eastern US; incised channels ID RIVER DRAINAGE-BASIN; RIPARIAN VEGETATION; CHANNEL RESPONSE; COLORADO PLATEAU; EXTREME FLOODS; BANK EROSION; NEW-MEXICO; UTAH; ARIZONA; STREAMS AB Alluvial channel bed incision and bank widening have been reported in both the south-western and south-eastern US throughout the past century. Distinct regional differences in climate and landscape properties likely influence the rate of erosion. This study discusses regional differences in hydraulic driving forces and substrate resistance and tests the hypothesis that regional differences exist in average rates of channel incision, bank erosion, and knickpoint retreat. Specifically, we hypothesize that erosion rates are higher in south-western US streams and reason that this is because of greater flood magnitudes and limited substrate resistance. A review of the literature documenting incision, bank erosion, and knickpoint retreat, however, indicates that intra-regional differences are larger than inter-regional differences and that average rates in the south-western US are either statistically similar or less than the rates in parts of the south-eastern US. This could either be a result of strong intra-regional hydroclimatic and substrate variability or because average erosion rate may not be an appropriate metric for inter-regional comparisons because of the variability between case studies associated with the field methods to measure erosion, duration of study period, and time since disturbance to the channel. Nevertheless, these findings provide a basis for future evaluations of the relative importance of different controls on driving and resisting forces in these and other landscapes characterized by rapid channel incision and arroyo formation.

Many enteric viruses have been identified in turkeys and chickens, including avian astroviruses, rotaviruses, reoviruses, and coronaviruses. Through the application of a molecular screening method targeting particle-associated nucleic acid (PAN), we recently described the detection and partial characterization of a novel enteric parvovirus in chickens. Subsequent surveys of intestinal homogenates from turkeys and chickens in the United States revealed widespread occurrence of parvovirus in poultry. Here we report the first full genome sequence of a novel chicken parvovirus, ChPV ABU-P1. ChPV ABU-P1 genome organization, predicted amino acid sequence, and phylogenetic relationships with other described parvoviruses are discussed. Published by Elsevier Inc. C1 [Day, J.

TI A 2cM genome-wide scan of European Holstein cattle affected by classical BSE SO BMC GENETICS LA English DT Article ID BOVINE SPONGIFORM ENCEPHALOPATHY; QUANTITATIVE TRAIT LOCI; PRNP PROMOTER POLYMORPHISMS; PRECURSOR PROTEIN GENE; RADIATION HYBRID PANEL; PRION PROTEIN; DEFICIENT MICE; CART PEPTIDE; SUSCEPTIBILITY; IDENTIFICATION AB Background: Classical bovine spongiform encephalopathy (BSE) is an acquired prion disease that is invariably fatal in cattle and has been implicated as a significant human health risk. Polymorphisms that alter the prion protein of sheep or humans have been associated with variations in transmissible spongiform encephalopathy susceptibility or resistance. In contrast, there is no strong evidence that non-synonymous mutations in the bovine prion gene (PRNP) are associated with classical BSE disease susceptibility. However, two bovine PRNP insertion/deletion polymorphisms, one within the promoter region and the other in intron 1, have been associated with susceptibility to classical BSE. These associations do not explain the full extent of BSE susceptibility, and loci outside of PRNP appear to be associated with disease incidence in some cattle populations. To test for associations with BSE susceptibility, we conducted a genome wide scan using a panel of 3,072 single nucleotide polymorphism (SNP) markers on 814 animals representing cases and control Holstein cattle from the United Kingdom BSE epidemic. Results: Two sets of BSE affected Holstein cattle were analyzed in this study, one set with known family relationships and the second set of paired cases with controls. The family set comprises half-sibling progeny from six sires. The progeny from four of these sires had previously been scanned with microsatellite markers. The results obtained from the current analysis of the family set yielded both some supporting and new results compared with those obtained in the earlier study. The results revealed 27 SNPs representing 18 chromosomes associated with incidence of BSE disease. These results confirm a region previously reported on chromosome 20, and identify additional regions on chromosomes 2, 14, 16, 21 and 28. This study did not identify a significant association near the PRNP in the family sample set. The only association found in the PRNP region was in the case-control sample set and this was not significant after multiple test correction. The genome scan of the case-control animals did not identify any associations that passed a stringent genome-wide significance threshold. Conclusions: Several regions of the genome are statistically associated with the incidence of classical BSE in European Holstein cattle. Further investigation of loci on chromosomes 2, 14, 16, 20, 21 and 28 will be required to uncover any biological significance underlying these marker associations.

TI A Spontaneous Dominant-Negative Mutation within a 35S::AtMYB90 Transgene Inhibits Flower Pigment Production in Tobacco SO PLOS ONE LA English DT Article ID MYB TRANSCRIPTION FACTOR; R2R3-MYB GENE FAMILY; ARABIDOPSIS-THALIANA; ANTHOCYANIN BIOSYNTHESIS; ZEA-MAYS; EXPRESSION ANALYSIS; MOLECULAR ANALYSIS; ACTIVATION DOMAIN; REGULATORY GENE; C1-I ALLELE AB Background: In part due to the ease of visual detection of phenotypic changes, anthocyanin pigment production has long been the target of genetic and molecular research in plants. Specific members of the large family of plant myb transcription factors have been found to play critical roles in regulating expression of anthocyanin biosynthetic genes and these genes continue to serve as important tools in dissecting the molecular mechanisms of plant gene regulation. Findings: A spontaneous mutation within the coding region of an Arabidopsis 35S::AtMYB90 transgene converted the activator of plant-wide anthocyanin production to a dominant-negative allele (PG-1) that inhibits normal pigment production within tobacco petals. Sequence analysis identified a single base change that created a premature nonsense codon, truncating the encoded myb protein. The resulting mutant protein lacks 78 amino acids from the wild type C-terminus and was confirmed as the source of the white-flower phenotype. A putative tobacco homolog of AtMYB90 (NtAN2) was isolated and found to be expressed in flower petals but not leaves of all tobacco plants tested. Using transgenic tobacco constitutively expressing the NtAN2 gene confirmed the NtAN2 protein as the likely target of PG-1-based inhibition of tobacco pigment production. Conclusions: Messenger RNA and anthocyanin analysis of PG-1Sh transgenic lines (and PG-1Sh x purple 35S:: NtAN2 seedlings) support a model in which the mutant myb transgene product acts as a competitive inhibitor of the native tobacco NtAN2 protein. This finding is important to researchers in the field of plant transcription factor analysis, representing a potential outcome for experiments analyzing in vivo protein function in test transgenic systems that over-express or mutate plant transcription factors.
