Bologna slices containing SL and SDA in the formulation were dipped in pediocin, surface inoculated, and treated at various temperatures using combinations of parameters determined by central composite design. D-values were calculated. The observed D-values ranged from 2.8 min at 60 degrees C to 24.61 min at 56.3 degrees C. Injury ranged from 9.1 to 76% under various conditions. The observed D-values were analyzed using second order response surface regression for temperature, SL, SDA, and pediocin, and a predictive model was developed. Predicted D-values were calculated and ranged from 3.7 to 19 min for various combinations of parameters. Temperature alone reduced the predicted D-values from 33.96 min at 56.3 degrees C to 11.51 min at 60 degrees C. Addition of SL showed a protective effect. Other combination treatments either reduced or increased D-values depending on temperature. The combination of SL and SDA was effective at lower temperatures, however, higher levels of SDA at higher temperatures made the organism more heat resistant. Pediocin (up to 5000 AU) with increasing temperature and SDA reduced D-values. Depending on temperature and concentration, the interactions between various additives can affect thermal inactivation of L. monocytogenes on bologna. Starvation rendered L. monocytogenes more susceptible to heat and additives. (C) 2010 Elsevier Ltd. All rights reserved.

These mycotoxins can induce toxicoses in animals and humans and can contribute to the ability of some fusaria to cause plant disease. Production of the trichothecene 3-acetyldeoxynivalenol (3-ADON) versus 15-acetyldeoxynivalenol (15-ADON) is an important phenotypic difference within and among some Fusarium species. However, until now, the genetic basis for this difference in chemotype has not been identified. Here, we identified consistent DNA sequence differences in the coding region of the trichothecene biosynthetic gene TRI8 in 3-ADON and 15-ADON strains. Functional analyses of the TRI8 enzyme (Tri8) in F. graminearum, the predominant cause of wheat head blight in North America and Europe, revealed that Tri8 from 3-ADON strains catalyzes deacetylation of the trichothecene biosynthetic intermediate 3,15-diacetyldeoxynivalenol at carbon 15 to yield 3-ADON, whereas Tri8 from 15-ADON strains catalyzes deacetylation of 3,15-diacetyldeoxynivalenol at carbon 3 to yield 15-ADON. Fusarium strains that produce the trichothecene nivalenol have a Tri8 that functions like that in 15-ADON strains. TRI3, which encodes a trichothecene carbon 15 acetyltransferase, was found to be functional in all three chemotypes. Together, our data indicate that differential activity of Tri8 determines the 3-ADON and 15-ADON chemotypes in Fusarium. Published by Elsevier Inc.

TI Field measurement and scaled-down wind-tunnel model measurement of airflow field over a barchan dune SO JOURNAL OF ARID ENVIRONMENTS LA English DT Article DE Barchan dune; Field measurement; Wind profile; Wind-tunnel simulation ID TRANSVERSE DUNES; SAND TRANSPORT; STOSS SLOPE; ROUGHNESS; VELOCITY; EROSION; SOIL; SIMULATION; FLUX; HILL AB Airflow is measured over a barchan dune in the field and over a scaled-down model in a wind tunnel. The change of the flow speed over the stoss side is represented by the change of speed-up ratio. According to the field measurement, the wind profiles within 0-3m above the stoss can be divided into two segments. The lower segment, about 0.66 m thick, is the inner-boundary layer, within which the friction velocities derived from the wind profiles increase from the upwind inter-dune region to the upper stoss, and then decrease near the dune top. This change, together with the changes of airflow field, speed-up ratio and sand flux, is related to the morphological change and contributes to the stable shape and height of a barchan dune. In the wind tunnel, airflow varies in a similar way as in the field, with the speed-up ratios constantly higher than 1.0 and increasing along the stoss slope. While the segmentation of wind profiles also occurs in the wind tunnel, friction velocities derived from the wind profiles decrease along the stoss, indicating a very thin inner-boundary layer above the wind tunnel model where the detailed wind-speed change becomes difficult to measure using the present instruments.

We hypothesized 1) competition would be intense among invasive and native species, but 2) competition would be unimportant in explaining variation in target plant biomass and survivorship relative to other factors driving these variables. We performed a two year addition series field experiment to quantify competition intensity and importance. Densities of two invasive (cheatgrass and medusahead) and two native (Sandberg's bluegrass and bluebunch wheatgrass) species were arranged in monocultures and mixtures of two, three and four species, producing varying total densities and species proportions. Multiple linear regression models predicting individual plant biomass and survivorship were developed. Based on biomass, competition intensity coefficients ranged from -0.38 to 0.63 with R(2) < 0.06. All survivorship data produced poor fitting regression models (R(2) < 0.05). Our results suggest neither competition intensity nor importance influenced plant dominance in resource poor environments during the two years of establishment. Land managers may be more successful at restoration of resource poor ecosystems by overcoming abiotic barriers to plant establishment rather than focusing on plant plant interactions.

TI Ultrafiltration of Thin Stillage from Conventional and E-Mill Dry Grind Processes SO APPLIED BIOCHEMISTRY AND BIOTECHNOLOGY LA English DT Article DE Biofuels; Membrane filtration; Nutrient separation; Ethanol ID CORN; STREAMS AB We used ultrafiltration (UF) to evaluate membrane filtration characteristics of thin stillage and determine solids and nutrient compositions of filtered streams. To obtain thin stillage, corn was fermented using laboratory methods. UF experiments were conducted in batch mode under constant temperature and flow rate conditions. Two regenerated cellulose membranes (10 and 100 kDa molecular weight cutoffs) were evaluated with the objective of retaining solids as well as maximizing permeate flux. Optimum pressures for 10 and 100 kDa membranes were 207 and 69 kPa, respectively. Total solids, ash, and neutral detergent fiber contents of input TS streams of dry grind and E-Mill processes were similar; however, fat and protein contents were different (p < 0.05). Retentate obtained from conventional thin stillage fractionation had higher mean total solids contents (27.6% to 27.8%) compared to E-Mill (22.2% to 23.4%). Total solids in retentate streams were found similar to those from commercial evaporators used in industry (25% to 35% total solids). Fat contents of retentate streams ranged from 16.3% to 17.5% for the conventional process. A 2% increment in fat concentration was observed in the E-Mill retentate stream. Thin stillage ash content was reduced 60% in retentate streams. C1 [Arora, Amit; Wang, Ping; Singh, Vijay; Tumbleson, M. E.; Rausch, Kent D.] Univ Illinois, Urbana, IL 61801 USA.

And the efficiency of ethanol production from enzymatic hydrolysate mixed with pretreatment hydrolysate of softwood by bisulfite and sulfuric acid pretreatment process was reported. The results showed that in the combined treatments of the two inhibitors, cell growth was not affected at 1 g/L each of furfural and HMF. When 3 g/L each of furfural and HMF was applied, the adapted strain responded with an extended lag phase of 24 h. Both in batch and fed-batch runs of combined hydrolysate fermentation, the final ethanol concentrations were above 20.0 g/L and the ethanol yields (Y(p/s)) on the total amount of fermentable sugar presented in the pre-treated materials were above 0.40 g/g. It implies the great promise of the yeast strain for improving ethanol production from softwood due to its high ability of metabolizing inhibitor compounds of furfural and HMF.

QF was manufactured from pasteurized homogenized milk using a commercial procedure without starter cultures; up to 2.5% (w/w) NaCl was added to milled curds. Moisture, fat, and protein levels were unaffected by salt content; the pH in QF made with 0-1.0% NaCl decreased with storage. Water activity increased significantly over storage time, and was inversely proportional to NaCl content. Total colour change after heating, and chroma values of cheese heated at 232 degrees C for 5 min decreased as NaCl levels increased; chroma values before and after heating increased with storage time. Increasing NaCl content increased shear stress and shear rigidity values. Texture profile analysis and small-amplitude oscillatory shear analyses showed no rheological differences between cheeses due to NaCl content or storage time. Published by Elsevier Ltd.

The objective of this study was to determine the moisture diffusivity of rough rice under IR heating followed by cooling. The effects of initial moisture content, rice temperature, drying bed thickness, tempering, and cooling methods on moisture diffusivity and moisture diffusivity coefficient were investigated. Samples of freshly harvested medium grain rice (M202 variety) with initial moisture content (MC) of 25.8, 31.2 and 33.8 g moisture/100 g dry solid were used. They were dried with IR radiation intensity of 5348 W/m(2), for six exposure times, 15, 30, 40, 60, 90 and 1205. The tested drying bed thicknesses were single-layer, 5 mm and 10 mm. The unsteady diffusion equation based on Fick's law and slope methods were used to describe moisture diffusivity. The results indicated that rough rice moisture diffusivities under IR heating and cooling were significantly affected by rice temperature and tempering treatment, respectively. High heating rate and moisture diffusivity were achieved with IR heating. It took only 60, 90 and 120 s to achieve about 60 degrees C rice temperature with corresponding moisture diffusivities of 4.8 x 10(-9), 3.6 x 10(-9) and 3.4 x 10(-9) m(2)/s during heating for drying bed thicknesses of a single layer, 5 mm and 10 mm, respectively. The moisture diffusivity coefficients during heating and cooling of IR dried rice with tempering were much higher than those of convective drying, which reflected the high drying rate of the IR drying method.

However, many studies show that the spatial distribution of ignition locations, whether human-caused or natural, is non-random. Thus, predictions from fire simulations based on random ignitions may be unrealistic. However, the extent to Which the assumption of ignition location affects the predictions of fire simulation models has never been systematically explored. Our goal was to assess the difference in fire simulations that are based on random versus non-random ignition location patterns. We conducted four sets of 6000 FARSITE simulations for the Santa Monica Mountains in California to quantify the influence of random and non-random ignition locations and normal and extreme weather conditions on fire size distributions and spatial patterns of burn probability. Under extreme weather conditions, fires were significantly larger for non-random ignitions compared to random ignitions (mean area of 344.5 ha and 230.1 ha, respectively), but burn probability maps were highly correlated (r = 0.83). Under normal weather, random ignitions produced significantly larger fires than non-random ignitions (17.5 ha and 13.3 ha, respectively), and the spatial correlations between burn probability maps were not high (r = 0.54), though the difference in the average burn probability was small. The results of the study suggest that the location of ignitions used in fire simulation models may substantially influence the spatial predictions of fire spread patterns. However, the spatial bias introduced by using a random ignition location model may be minimized if the fire simulations are conducted under extreme weather conditions when fire spread is greatest.

This usually occurs after severely deteriorated sugarcane has been processed, but the specific cause is unknown and only limited correction has been achievable. At the end of the 2006 sugarcane processing season, HTB and normal massecuites and molasses were collected from four Louisiana factories. Compared to normal samples, the HTB samples had 9.1-33.2% lower heat conductivity and 10.0-49.2% higher heat resistivity. The more HTB a sample is, the greater the increase in heat resistivity compared to the corresponding decrease in heat conductivity. Excess lime addition to neutralise acids during juice clarification is not the direct cause of hard boiling. Oscillatory deformation rheology applied at 20 degrees C to normal molasses samples gave typical mechanical spectra of concentrated solutions. In contrast, a highly viscous, intermolecular (gel) network was present in the HTB molasses, which would explain the difficulty of removing entrapped water on boiling. Polysaccharides in the samples were characterised. GFC, TLC. and methylation analyses suggested the presence of an arabinogalactan and endo-dextranase-resistant dextran structures. The HTB phenomenon may have different causes and mannitol is a contributing factor. Published by Elsevier Ltd. C1 [Eggleston, Gillian] USDA ARS, So Reg Res Ctr, New Orleans, LA 70124 USA.

All sample extraction methods were appropriate for qualitative results only. Different extraction procedures showed altered component composition in 'Pinot noir' berries, possibly due to the localisation of the compounds of interest within the grape and how those compounds were extracted from the berry. Sample extraction is an often-overlooked part of berry evaluations, but this study illustrates that it should be carefully considered prior to berry component analysis for its influence upon measurements.

TI Enhancing RUSLE to include runoff-driven phenomena SO HYDROLOGICAL PROCESSES LA English DT Article DE RUSLE; runoff; erosion; concentrated flow; sediment; ephemeral gully ID CURVE NUMBER; WEATHER GENERATOR; GOODWIN CREEK; GULLY EROSION; MODEL; HYDROLOGY AB RUSLE2 (Revised Universal Soil Loss Equation) is the most recent in the family of Universal Soil Loss Equation (USLE)/RUSLE/RUSLE2 models proven to provide robust estimates of average annual sheet and rill erosion from a wide range of land use, soil, and climatic conditions. RUSLE2's capabilities have been expanded over earlier versions using methods of estimating time-varying runoff and process-based sediment transport routines so that it can estimate sediment transport/deposition/delivery on complex hillslopes. In this report we propose and evaluate a method of predicting a series of representative runoff events whose sizes, durations, and timings are estimated from information already in the RUSLE2 database. The methods were derived from analysis of 30-year simulations using a widely accepted climate generator and runoff model and were validated against additional independent simulations not used in developing the index events, as well as against long-term measured monthly rainfall/runoff sets. Comparison of measured and RUSLE2-predicted monthly runoff suggested that the procedures outlined may underestimate plot-scale runoff during periods of the year with greater than average rainfall intensity, and a modification to improve predictions was developed. In order to illustrate the potential of coupling RUSLE2 with a process-based channel erosion model, the resulting set of representative storms was used as an input to the channel routines used in Chemicals, Runoff, and Erosion from Agricultural Management Systems (CREAMS) to calculate ephemeral gully erosion. The method was applied to a hypothetical 5-ha field cropped to cotton in Marshall County, MS, bisected by a potential ephemeral gully having channel slopes ranging from 0.5 to 5% and with hillslopes on both sides of the channel with 5% steepness and 22.1 m length. Results showed the representative storm sequence produced reasonable results in CREAMS indicating that ephemeral gully erosion may be of the same order of magnitude as sheet and rill erosion.

This study examined subsurface runoff in two hillslopes, one aspen dominated, the other conifer dominated, adjacent to a first order stream in snow-driven northern Utah. Snow accumulation, soil moisture, trenchflow and streamflow were examined in hillslopes and their adjacent stream. Snow water equivalents (SWEs) were greater under aspen stands compared to conifer, the difference increasing with higher annual precipitation. Semi-variograms of shallow spatial soil moisture patterns and transects of continuous soil moisture showed no increase in soil moisture downslope, suggesting the absence of subsurface flow in shallow (similar to 12 cm) soil layers of either vegetation type. However, a clear threshold relationship between soil moisture and streamflow indicated hillslope-stream connectivity, deeper within the soil profile. Subsurface flow was detected at similar to 50 cm depth, which was sustained for longer in the conifer hillslope. Soil profiles under the two vegetation types varied, with deep aspen soils having greater water storage capacity than shallow rocky conifer soils. Though SWEs were less under the conifers, the soil profile had less water storage capacity and produced more subsurface lateral flow during the spring snowmelt.

TI High protein diet maintains glucose production during exercise-induced energy deficit: a controlled trial SO NUTRITION & METABOLISM LA English DT Article DE carbohydrate metabolism gluconeogenesis; protein intake; negative energy balance; stable isotopes ID WEIGHT-LOSS; NITROGEN-BALANCE; BODY-COMPOSITION; STABLE-ISOTOPE; ADULT WOMEN; METABOLISM; MEN; GLUCONEOGENESIS; CARBOHYDRATE; TURNOVER AB Background: Inadequate energy intake induces changes in endogenous glucose production (GP) to preserve muscle mass. Whether addition provision of dietary protein modulates GP response to energy deficit is unclear. The objective was to determine whether exercise-induced energy deficit effects on glucose metabolism are mitigated by increased dietary protein. Methods: Nineteen men ([mean +/- SD] 23 +/- 2 y, VO(2peak) 59 +/- 5 ml.kg(-1).min(-1)) were divided into three groups, two consuming moderate (MP; 0.9 g protein kg(-1) d(-1)), and one high (HP; 1.8 g protein kg(-1) d(-1)) protein diets (55% energy from carbohydrate) for 11 days. Following 4 days of energy balance (D1-4), energy expenditure was increased for 7 days (D5-12) in all groups. Energy intake was unchanged in two, creating a 1000 kcal d(-1) deficit (DEF-MP, DEF-HP; n = 6, both groups), whereas energy balance was maintained in the third (BAL-MP, n = 7). Biochemical markers of substrate metabolism were measured during fasting rest on D4 and D12, as were GP and contribution of gluconeogenesis to endogenous glucose production (f(gng)) using 4-h primed, continuous infusions of [6,6-(2)H(2)] glucose (dilution-method) and [2-(13)C] glycerol (MIDA technique). Glycogen breakdown (GB) was derived from GP and f(gng). Results: Plasma beta-hydroxybutyrate levels increased, and plasma glucose and insulin declined from D4 to D12, regardless of group. DEF-MP experienced decreased plasma GP from D4 to D12 ([mean change +/- SD] 0.24 +/- 0.24 mg.kg(-1).min(-1)), due to reduced GB from D4 (1.40 +/- 0.28 mg.kg(-1).min(-1)) to D12 (1.16 +/- 0.17 mg.kg(-1).min(-1)), P < 0.05. Conversely, BAL-MP and DEF-HP sustained GP from D4 to D12 ([mean change +/- SD] 0.1 +/- 0.5 and 0.0 +/- 0.2 mg.kg(-1).min(-1), respectively) by maintaining GB. Conclusion: Exercise-induced energy deficit decreased GP and additional dietary protein mitigated that effect.

This disease has led to multi-million dollar losses for growers in the central and western United States over the past decade and impacts the livelihood of potato farmers in Mexico and New Zealand. ZC is associated with 'Candidatus Liberibacter solanacearum', a fastidious alpha-proteobacterium that is transmitted by a phloem-feeding psyllid vector, Bactericera cockerelli Sulc. Research on this disease has been hampered by a lack of robust culture methods and paucity of genome sequence information for 'Ca. L. solanacearum'. Here we present the sequence of the 1.26 Mbp metagenome of 'Ca. L. solanacearum', based on DNA isolated from potato psyllids. The coding inventory of the 'Ca. L. solanacearum' genome was analyzed and compared to related Rhizobiaceae to better understand 'Ca. L. solanacearum' physiology and identify potential targets to develop improved treatment strategies. This analysis revealed a number of unique transporters and pathways, all potentially contributing to ZC pathogenesis. Some of these factors may have been acquired through horizontal gene transfer. Taxonomically, 'Ca. L. solanacearum' is related to 'Ca. L. asiaticus', a suspected causative agent of citrus huanglongbing, yet many genome rearrangements and several gene gains/losses are evident when comparing these two Liberibacter. species. Relative to 'Ca. L. asiaticus', 'Ca. L. solanacearum' probably has reduced capacity for nucleic acid modification, increased amino acid and vitamin biosynthesis functionalities, and gained a high-affinity iron transport system characteristic of several pathogenic microbes.

NMR studies showed that protonation of 8 (2-thienyl system) inhibited photoisomerization (Z-E) about the exocyclic double bond but that protonation of 7c (E + Z) (2-pyrryl system) gave only 7cE. Fluorescence studies revealed enhancement of fluorescence intensity of 7c and 7b,e (furyl system) below pH 2.5 and gave a similar result for loa (pyridyl system) below pH 6. Quantum yields at pH 1 were low, probably due to excited state proton transfer (ESPT). (C) 2010 Elsevier Ltd. All rights reserved.

Among the naturally occurring trichothecenes in food and feed, T-2 toxin is a cytotoxic fungal secondary metabolite produced by various species of Fusarium. Following ingestion, T-2 toxin causes acute and chronic toxicity and induces apoptosis in the immune system and fetal tissues. T-2 toxin is usually metabolized and eliminated after ingestion, yielding more than 20 metabolites. Consequently, there is a possibility of human consumption of animal products contaminated with T-2 toxin and its metabolites. Several methods for the determination of T-2 toxin based on traditional chromatographic, immunoassay, or mass spectroscopy techniques are described. This review will contribute to a better understanding of T-2 toxin exposure in animals and humans and T-2 toxin metabolism, toxicity, and analytical methods, which may be useful in risk assessment and control of T-2 toxin exposure.

Here, we evaluated 38 broccoli accessions for their capacity to accumulate Se and for their responses to selenate treatment in terms of nutritional qualities and sulfur gene expresion. We found that the total Se content varied with over 2-fold difference among the leaf tissues of broccoli accessions when the plants were treated with 20 mu M Na2SeO4. Approximately half of total Se accumulated in leaves was Se-methylselenocysteine and selenomethionine. Transcriptional regulation of adenosine S'-phosphosulfate sulfurylase and selenocysteine Se-methyltransferase gene expression might contribute to the different levels of Se accumulation in broccoli. Total glucosinolate contents were not affected by the concentration of selenate application for the majority of broccoli accessions. Essential micronutrients (i.e., Fe, Zn, Cu, and Mn) remained unchanged among half of the germplasm. Moreover, the total antioxidant capacity was greatly stimulated by selenate in over half of the accessions. The diverse genotypic variation in Se, glucosinolate, and antioxidant contents among accessions provides the opportunity to breed broccoli cultivars that simultaneously accumulate Se and other health benefit compounds.

Oligosaccharides were fractionated according to their molecular weight, and their effect on the growth of different bacterial groups was studied. To determine the structure (position and configuration of glycosidic linkages) function relationship, their properties were compared to those of DSR maltose acceptor products (DSRMal) and of recognized prebiotic carbohydrates (fructo-oligosaccharides, FOS). Cellobiose acceptor products (DSRCel) showed bifidogenic properties similar to those of FOS. However, no significant differences related to molecular weight or isomeric configurations were found for DSRCel and DSRMal products. C1 [Ruiz-Matute, Ana I.; Brokl, Michal; Sanz, M.

Experimental studies have linked theaflavins to beneficial health effects, some of which are related to interactions with the cell membrane. The molecular interaction of theaflavins with membranes was explored by simulating the interactions of three theaflavin molecules (theaflavin, theaflavin-3-gallate, and theaflavin-3,3'-digallate) with a mixed bilayer composed of 1-palmitoyl-2-oleoyl phosphatidylcholine (POPC) and 1-palmitoy1-2-oleoyl phosphatidylethanolamine (POPE). The simulations show that the theaflavins evaluated have an affinity for the lipid bilayer surface via hydrogen bonding. The molecular structure of theaflavins influenced their configuration when binding to the bilayer surface, as well as their ability to form hydrogen bonds with the lipid headgroups. The theaflavin bilayer interactions studied here help to define structure function relationships of the theaflavins and provide a better understanding of the role of theaflavins in biological processes. The significance of the results are discussed in the context of black tea composition and bioactivity. C1 [Sirk, Timothy W.] USA, Macromol Sci & Technol Branch, Res Lab, Aberdeen, MD 21005 USA.

Successful introduction of waxy wheat varieties into commerce is predicated on a rapid methodology at the commodity point of sale that can test for the waxy condition. Near-infrared (NIR) reflectance spectroscopy, one such technology, was applied to a diverse set of hard winter (hexaploid) wheat breeders' lines representing all eight genotypic combinations of alleles at the wx-A1,wx-B1, and wx-Dl loci. These loci encode granule-bound starch synthase, the enzyme responsible for amylose synthesis. Linear discriminant analysis of principal components scores 1-4 was successful in identifying the fully waxy samples at typically greater than 90% accuracy; however, accuracy was reduced for partial and wild-type genotypes. It is suggested that the spectral sensitivity to waxiness is due to (1) the lipid amylose complex which diminishes with waxiness, (2) physical differences in endosperm that affect light scatter, or (3) changes in starch crystallinity.

The Freundlich equation adequately described behavior of aminocyclopyrachlor in soil. Freundlich sorption coefficient (K(f)) values ranged from 0.06 to 1.64 and 1/n values for ranged from 0.9 to 1.0. Sorption was correlated to OC (K(f,oc) ranged from 11 to 64) and clay contents. The lowest sorption was found for soils with very low OC contents (0.50-0.65%) and loamy-sand to sand textures. The 1/n values for desorption were lower than those observed for sorption, suggesting that aminocyclopyrachlor sorption by soil was not reversible; hysteresis coefficients ranged from 0.13 to 0.74. The results suggest that although aminocyclopyrachlor would be very mobile based on its sorption coefficients, its potential depth of leaching may be overestimated due to the hysteretic desorption.

EHEC colonize the intestinal mucosa and promote the formation of actin-rich pedestals via translocated type III effectors. Two EHEC type III secreted effectors, Tir and EspFu/TccP, are key players for pedestal formation. We discovered that an EHEC effector protein called Non-LEE-encoded Ligase (NleL) is an E3 ubiquitin ligase. In vitro, we showed that the NleL C753 residue is critical for its E3 ligase activity. Functionally, we demonstrated that NleL E3 ubiquitin ligase activity is involved in modulating Tir-mediated pedestal formation. Surprisingly, EHEC mutant strain deficient in the E3 ligase activity induced more pedestals than the wild-type strain. The canonical EPEC strain E2348/69 normally lacks the nleL gene, and the ectopic expression of the wild-type EHEC nleL, but not the catalytically-deficient nleL(C753A) mutant, in this strain resulted in fewer actin-rich pedestals. Furthermore, we showed that the C. rodentium NleL homolog is a E3 ubiquitin ligase and is required for efficient infection of murine colonic epithelial cells in vivo. In summary, our study demonstrated that EHEC utilizes NleL E3 ubiquitin ligase activity to modulate Tir-mediated pedestal formation.

To gain insights into the genetic architecture of quantitative resistance in maize, we evaluated a 5,000-inbred-line nested association mapping population for resistance to northern leaf blight, a maize disease of global economic importance. Twenty-nine quantitative trait loci were identified, and most had multiple alleles. The large variation in resistance phenotypes could be attributed to the accumulation of numerous loci of small additive effects. Genome-wide nested association mapping, using 1.6 million SNPs, identified multiple candidate genes related to plant defense, including receptor-like kinase genes similar to those involved in basal defense. These results are consistent with the hypothesis that quantitative disease resistance in plants is conditioned by a range of mechanisms and could have considerable mechanistic overlap with basal resistance.

Observational studies of patients with chronic kidney disease suggest increased homocysteine is a risk factor for cardiovascular disease. The impact of lowering total homocysteine levels in kidney transplant recipients is unknown. Methods and Results-In a double-blind controlled trial, we randomized 4110 stable kidney transplant recipients to a multivitamin that included either a high dose (n=2056) or low dose (n=2054) of folic acid, vitamin B6, and vitamin B12 to determine whether decreasing total homocysteine concentrations reduced the rate of the primary composite arteriosclerotic cardiovascular disease outcome (myocardial infarction, stroke, cardiovascular disease death, resuscitated sudden death, coronary artery or renal artery revascularization, lower-extremity arterial disease, carotid endarterectomy or angioplasty, or abdominal aortic aneurysm repair). Mean follow-up was 4.0 years. Treatment with the high-dose multivitamin reduced homocysteine but did not reduce the rates of the primary outcome (n=547 total events; hazards ratio [95% confidence interval]=0.99 [0.84 to 1.17]), secondary outcomes of all-cause mortality (n=431 deaths; 1.04 [0.86 to 1.26]), or dialysis-dependent kidney failure (n=343 events; 1.15 [0.93 to 1.43]) compared to the low-dose multivitamin. Conclusions-Treatment with a high-dose folic acid, B6, and B12 multivitamin in kidney transplant recipients did not reduce a composite cardiovascular disease outcome, all-cause mortality, or dialysis-dependent kidney failure despite significant reduction in homocysteine level.

Large-scale sequence analysis of viroid-specific small RNAs revealed active production from the upper portion of the pathogenicity and central domains, two regions previously thought to be underrepresented. Profiles of small RNA populations derived from PSTVd antigenomic RNA were more variable, with differences between infected Rutgers (severe symptoms) and Moneymaker (mild symptoms) plants pointing to possible cultivar-specific differences in small RNA synthesis and/or stability. Using microarray analysis, we monitored the effects of PSIVd infection on the expression levels of > 100 tomato genes containing potential binding sites for PSIVd small RNAs. Of 18 such genes down-regulated early in infection, two genes involved in gibberellin or jasmonic acid biosynthesis contain binding sites for PSTVd small RNAs in their respective ORFs.

SO VIROLOGY JOURNAL LA English DT Article DE human immunodeficiency virus HIV; antiviral; microbicide; plant extract; self-heal ID IMMUNODEFICIENCY-VIRUS TYPE-1; CHINESE MEDICINAL HERBS; IN-VITRO; METHANOL EXTRACTS; MOLECULAR CLONE; REPLICATION; CELLS; POLYSACCHARIDE; EXPRESSION; SURFACE AB Background: The mint family (Lamiaceae) produces a wide variety of constituents with medicinal properties. Several family members have been reported to have antiviral activity, including lemon balm (Melissa officinalis L.), sage (Salvia spp.), peppermint (Mentha x piperita L.), hyssop (Hyssopus officinalis L.), basil (Ocimum spp.) and self-heal (Prunella vulgaris L.). To further characterize the anti-lentiviral activities of Prunella vulgaris, water and ethanol extracts were tested for their ability to inhibit HIV-1 infection. Results: Aqueous extracts contained more anti-viral activity than did ethanol extracts, displaying potent antiviral activity against HIV-1 at sub mu g/mL concentrations with little to no cellular cytotoxicity at concentrations more than 100-fold higher. Time-of-addition studies demonstrated that aqueous extracts were effective when added during the first five hours following initiation of infection, suggesting that the botanical constituents were targeting entry events. Further analysis revealed that extracts inhibited both virus/cell interactions and post-binding events. While only 40% inhibition was maximally achieved in our virus/cell interaction studies, extract effectively blocked post-binding events at concentrations similar to those that blocked infection, suggesting that it was targeting of these latter steps that was most important for mediating inhibition of virus infectivity. Conclusions: We demonstrate that aqueous P. vulgaris extracts inhibited HIV-1 infectivity. Our studies suggest that inhibition occurs primarily by interference of early, post-virion binding events. The ability of aqueous extracts to inhibit early events within the HIV life cycle suggests that these extracts, or purified constituents responsible for the antiviral activity, are promising microbicides and/or antivirals against HIV-1.

TI Temperature dependent virulence of obligate and facultative fungal pathogens of honeybee brood SO VETERINARY MICROBIOLOGY LA English DT Article DE Apis mellifera; Aspergillus; Ascosphaera; Host-pathogen interactions; Temperature; Virulence ID CHALKBROOD DEVELOPMENT; ASCOSPHAERA-APIS; RESISTANCE; SPORES; BEE; GERMINATION; DISEASE AB Chalkbrood (Ascosphaera apis) and stonebrood (Aspergillus flavus) are well known fungal brood diseases of honeybees (Apis mellifera), but they have hardly been systematically studied because the difficulty of rearing larvae in vitro has precluded controlled experimentation. Chalkbrood is a chronic honeybee-specific disease that can persist in colonies for years, reducing both brood and honey production, whereas stonebrood is a rare facultative pathogen that also affects hosts other than honeybees and can likely survive outside insect hosts. Hive infection trials have indicated that accidental drops in comb temperature increase the prevalence of chalkbrood, but it has remained unclear whether virulence is directly temperature-dependent. We used a newly established in vitro rearing technique for honeybee larvae to test whether there are systematic temperature effects on mortality induced by controlled infections, and whether such effects differed between the two fungal pathogens. We found that increasing spore dosage at infection had a more dramatic effect on mortality from stonebrood compared to chalkbrood. In addition, a 24 h cooling period after inoculation increased larval mortality from chalkbrood infection, whereas such a cooling period decreased mortality after stonebrood infection. These results raise interesting questions about honeybee defenses against obligate and facultative pathogens and about the extent to which stress factors in the host (dis)favor pathogens with lesser degrees of specialization.

TI The PLIN4 Variant rs8887 Modulates Obesity Related Phenotypes in Humans through Creation of a Novel miR-522 Seed Site SO PLOS ONE LA English DT Article ID FOOD FREQUENCY QUESTIONNAIRE; FACTOR-BINDING SITES; KAPPA-B ACTIVATION; BODY-MASS INDEX; PERILIPIN GENE; ADIPOSE-TISSUE; FATTY-ACIDS; TNF-ALPHA; EICOSAPENTAENOIC ACID; ADIPOCYTE LIPOLYSIS AB PLIN4 is a member of the PAT family of lipid storage droplet (LSD) proteins. Associations between seven single nucleotide polymorphisms (SNPs) at human PLIN4 with obesity related phenotypes were investigated using meta-analysis followed by a determination if these phenotypes are modulated by interactions between PLIN4 SNPs and dietary PUFA. Samples consisted of subjects from two populations of European ancestry. We demonstrated association of rs8887 with anthropometrics. Meta-analysis demonstrated significant interactions between the rs8887 minor allele with PUFA n3 modulating anthropometrics. rs884164 showed interaction with both n3 and n6 PUFA modulating anthropometric and lipid phenotypes. In silico analysis of the PLIN4 3'UTR sequence surrounding the rs8887 minor A allele predicted a seed site for the human microRNA-522 (miR-522), suggesting a functional mechanism. Our data showed that a PLIN4 3'UTR luciferase reporter carrying the A allele of rs8887 was reduced in response to miR-522 mimics compared to the G allele. These results suggest variation at the PLIN4 locus, and its interaction with PUFA as a modulator of obesity related phenotypes, acts in part through creation of a miR-522 regulatory site.

TI Using RNA-Seq for gene identification, polymorphism detection and transcript profiling in two alfalfa genotypes with divergent cell wall composition in stems SO BMC GENOMICS LA English DT Article ID MEDICAGO-SATIVA L.; MASKING BIASED PROBES; SUCROSE TRANSPORTER; CELLULOSE SYNTHESIS; DOWN-REGULATION; SNP DISCOVERY; PHOSPHATE DEFICIENCY; OPTIMIZING ANALYSIS; EXPRESSION ANALYSIS; TRANSGENIC ALFALFA AB Background: Alfalfa, [Medicago sativa (L.) sativa], a widely-grown perennial forage has potential for development as a cellulosic ethanol feedstock. However, the genomics of alfalfa, a non-model species, is still in its infancy. The recent advent of RNA-Seq, a massively parallel sequencing method for transcriptome analysis, provides an opportunity to expand the identification of alfalfa genes and polymorphisms, and conduct in-depth transcript profiling. Results: Cell walls in stems of alfalfa genotype 708 have higher cellulose and lower lignin concentrations compared to cell walls in stems of genotype 773. Using the Illumina GA-II platform, a total of 198,861,304 expression sequence tags (ESTs, 76 bp in length) were generated from cDNA libraries derived from elongating stem (ES) and post-elongation stem (PES) internodes of 708 and 773. In addition, 341,984 ESTs were generated from ES and PES internodes of genotype 773 using the GS FLX Titanium platform. The first alfalfa (Medicago sativa) gene index (MSGI 1.0) was assembled using the Sanger ESTs available from GenBank, the GS FLX Titanium EST sequences, and the de novo assembled Illumina sequences. MSGI 1.0 contains 124,025 unique sequences including 22,729 tentative consensus sequences (TCs), 22,315 singletons and 78,981 pseudo-singletons. We identified a total of 1,294 simple sequence repeats (SSR) among the sequences in MSGI 1.0. In addition, a total of 10,826 single nucleotide polymorphisms (SNPs) were predicted between the two genotypes. Out of 55 SNPs randomly selected for experimental validation, 47 (85%) were polymorphic between the two genotypes. We also identified numerous allelic variations within each genotype. Digital gene expression analysis identified numerous candidate genes that may play a role in stem development as well as candidate genes that may contribute to the differences in cell wall composition in stems of the two genotypes. Conclusions: Our results demonstrate that RNA-Seq can be successfully used for gene identification, polymorphism detection and transcript profiling in alfalfa, a non-model, allogamous, autotetraploid species. The alfalfa gene index assembled in this study, and the SNPs, SSRs and candidate genes identified can be used to improve alfalfa as a forage crop and cellulosic feedstock. C1 [Yang, S.

Neospora caninum-associated abortion may exhibit both endemic and epidemic patterns. It was reported that the epidemic outbreaks took place in the form of "abortion storms" and were not significantly correlated with seasonal changes or consumption of any particular feeds; and thus, the mechanisms by which the epidemic "abortion storms" are triggered remain unclear. Annual ryegrass toxicity (ARGT) is a severe or fatal neurological disorder of livestock of Australia and South Africa. This disorder is caused by the ingestion of several plant genera (Lolium, Polypogon, and Agrostis) colonized by a nematode (Anguina sp.) and a bacterium, Rathayibacter toxicus. Corynetoxins (CTs) produced by R. toxicus contaminate plants which are in turn ingested by sheep and cattle, causing severe or often fatal hepatocerebral disorders in affected animals. We hypothesize that N. caninum-associated fetal deaths and abortions in cattle may be potentiated by pre-exposure of sublethal levels of CF-contaminated plants prior to N. caninum infection or reactivation of a latent infection. The exposure of sublethal CTs may not cause clinical diseases, but may increase susceptibility to pathogens such as N. caninum. Indeed, CT poisoning surviving pregnant sheep can have up to 10% abortions. The present study investigated whether animals pre-exposed to tunicamycins (TMs), a functional substitute for CTs, had a lowered resistance to sublethal experimental infection by N. caninum tachyzoites in mice. The results showed that sublethal doses of TMs or N. caninum alone did not cause significant deaths. Sublethal doses of N. caninum induced high mortality in TM-treated mice in a dose dependent manner. When mice were treated with a low dose of TMs (5 mu g/mouse), as few as 2.5 x 10(6) tachyzoites were needed to induce more than 30% of mortality which is equivalent to the mortality rate caused by 40 x 10(6) tachyzoites. Spleen cells of mice treated with TMs had reduced (p < 0.05) Neospora antigen-induced interferon-gamma (IFN-g) production and Con A-stimulated proliferation. The results suggest that CT contaminated plants, when exposed to animals under natural conditions, may contribute to lowered host resistance and increased N. caninum-associated fetal morbidity and mortality in affected animals.

TI The Complete Genome Sequence of Fibrobacter succinogenes S85 Reveals a Cellulolytic and Metabolic Specialist SO PLOS ONE LA English DT Article ID OUTER-MEMBRANE PROTEINS; BACTEROIDES-SUCCINOGENES; RUMINOCOCCUS-FLAVEFACIENS; SYNERGISTIC INTERACTIONS; SIGNATURE SEQUENCES; ENDOGLUCANASE GENE; CONTINUOUS-CULTURE; RUMINAL BACTERIUM; MOLECULAR-CLONING; ESCHERICHIA-COLI AB Fibrobacter succinogenes is an important member of the rumen microbial community that converts plant biomass into nutrients usable by its host. This bacterium, which is also one of only two cultivated species in its phylum, is an efficient and prolific degrader of cellulose. Specifically, it has a particularly high activity against crystalline cellulose that requires close physical contact with this substrate. However, unlike other known cellulolytic microbes, it does not degrade cellulose using a cellulosome or by producing high extracellular titers of cellulase enzymes. To better understand the biology of F. succinogenes, we sequenced the genome of the type strain S85 to completion. A total of 3,085 open reading frames were predicted from its 3.84 Mbp genome. Analysis of sequences predicted to encode for carbohydrate-degrading enzymes revealed an unusually high number of genes that were classified into 49 different families of glycoside hydrolases, carbohydrate binding modules (CBMs), carbohydrate esterases, and polysaccharide lyases. Of the 31 identified cellulases, none contain CBMs in families 1, 2, and 3, typically associated with crystalline cellulose degradation. Polysaccharide hydrolysis and utilization assays showed that F. succinogenes was able to hydrolyze a number of polysaccharides, but could only utilize the hydrolytic products of cellulose. This suggests that F. succinogenes uses its array of hemicellulose-degrading enzymes to remove hemicelluloses to gain access to cellulose. This is reflected in its genome, as F. succinogenes lacks many of the genes necessary to transport and metabolize the hydrolytic products of non-cellulose polysaccharides. The F. succinogenes genome reveals a bacterium that specializes in cellulose as its sole energy source, and provides insight into a novel strategy for cellulose degradation.

Two pairs of tubercles present on the sterna of segments IX and X of the female pupae are useful in differentiating female from male pupae. The female genital opening is located anterior to the first pair of tubercles and forms a plateau in which the center has a light brown longitudinal depression that indicates the female genital opening. The male genital opening is a conspicuous, brown, longitudinal slit located between the two pairs of tubercles. The sex of the adult moth can be determined by examining the ventrocaudal segments of the abdomen. The last segment of the female abdomen is white, compressed laterally and at the tip, and the hairy anal papillae can be seen. In the male, the ventrocaudal end of the abdomen is black and robust. This information will be useful for laboratory and field diagnosis and while working on sex ratios of this important pest of cocoa. C1 [Posada, Francisco J.] IPM, Laurel, MD USA.

GSTZs are known to function as MAAIs [MAA (maleylacetoacetate) isomerases], which play a role in tyrosine catabolism by catalysing the isomerization of MAA to FAA (fumarylacetoacetate). As tyrosine metabolism in plants differs from animals, the significance of GSTZ/MAAI is unclear. In rice (Oryza saliva L.), a major QTL (quantitative trait locus) for seedling cold tolerance has been fine mapped to a region containing the genes OsGSTZ1 and OsGSTZ2. Sequencing of tolerant (ssp. japonica cv. M-202) and sensitive (ssp. indica cv. IR50) cultivars revealed two SNPs (single nucleotide polymorphisms) in OsGSTZ2 that result in amino acid differences (199V and N1841). Recombinant OsGSTZ2 containing the Val(99) residue found in IR50 had significantly reduced activity on MAA and DCA (dichloroacetic acid), but the Ile(184) residue had no effect. The distribution of the SNP (c.295A>G) among various rice accessions indicates a significant association with chilling sensitivity in rice seedlings. The results of the present study show that naturally occurring OsGSTZ2 isoforms differ in their enzymatic properties, which may contribute to the differential response to chilling stress generally exhibited by the two major rice subspecies.

TI Evaluation of Drought Indices Based on Thermal Remote Sensing of Evapotranspiration over the Continental United States SO JOURNAL OF CLIMATE LA English DT Article ID ASSIMILATION SYSTEM NLDAS; LAND EXCHANGE MODEL; SEVERITY INDEX; ENERGY FLUXES; SCALES; SOIL; VEGETATION; TEMPERATURE; PRODUCTS; CLIMATE AB The reliability of standard meteorological drought indices based on measurements of precipitation is limited by the spatial distribution and quality of currently available rainfall data. Furthermore, they reflect only one component of the surface hydrologic cycle, and they cannot readily capture nonprecipitation-based moisture inputs to the land surface system (e.g., irrigation) that may temper drought impacts or variable rates of water consumption across a landscape. This study assesses the value of a new drought index based on remote sensing of evapotranspiration (ET). The evaporative stress index (ESI) quantifies anomalies in the ratio of actual to potential ET (PET), mapped using thermal band imagery from geostationary satellites. The study investigates the behavior and response time scales of the ESI through a retrospective comparison with the standardized precipitation indices and Palmer drought index suite, and with drought classifications recorded in the U.S. Drought Monitor for the 2000-09 growing seasons. Spatial and temporal correlation analyses suggest that the ESI performs similarly to short-term (up to 6 months) precipitation-based indices but can be produced at higher spatial resolution and without requiring any precipitation data. Unique behavior is observed in the ESI in regions where the evaporative flux is enhanced by moisture sources decoupled from local rainfall: for example, in areas of intense irrigation or shallow water table. Normalization by PET serves to isolate the ET signal component responding to soil moisture variability from variations due to the radiation load. This study suggests that the ESI is a useful complement to the current suite of drought indicators, with particular added value in parts of the world where rainfall data are sparse or unreliable.

Brad TI Recent rates of forest harvest and conversion in North America SO JOURNAL OF GEOPHYSICAL RESEARCH-BIOGEOSCIENCES LA English DT Article ID LAND-USE CHANGE; REMOTELY-SENSED DATA; UNITED-STATES; CARBON STORAGE; PONDEROSA PINE; WOOD PRODUCTS; COVER LOSS; MANAGEMENT-PRACTICES; PACIFIC-NORTHWEST; TROPICAL FORESTS AB Incorporating ecological disturbance into biogeochemical models is critical for estimating current and future carbon stocks and fluxes. In particular, anthropogenic disturbances, such as forest conversion and wood harvest, strongly affect forest carbon dynamics within North America. This paper summarizes recent (2000-2008) rates of extraction, including both conversion and harvest, derived from national forest inventories for North America (the United States, Canada, and Mexico). During the 2000s, 6.1 million ha/yr were affected by harvest, another 1.0 million ha/yr were converted to other land uses through gross deforestation, and 0.4 million ha/yr were degraded. Thus about 1.0% of North America's forests experienced some form of anthropogenic disturbance each year. However, due to harvest recovery, afforestation, and reforestation, the total forest area on the continent has been roughly stable during the decade. On average, about 110 m(3) of roundwood volume was extracted per hectare harvested across the continent. Patterns of extraction vary among the three countries, with U.S. and Canadian activity dominated by partial and clear-cut harvest, respectively, and activity in Mexico dominated by conversion (deforestation) for agriculture. Temporal trends in harvest and clearing may be affected by economic variables, technology, and forest policy decisions. While overall rates of extraction appear fairly stable in all three countries since the 1980s, harvest within the United States has shifted toward the southern United States and away from the Pacific Northwest.

The existing imaging methods, however, mostly rely on predefined rectangular grids for sampling that ignore the natural cellular organization of the tissue. Here we demonstrate that laser ablation electrospray ionization (LAESI) MS can be utilized for in situ cell-by-cell imaging of plant tissues. The cell-by-cell molecular image of the metabolite cyanidin, the ion responsible for purple pigmentation in onion (Allium cepa) epidermal cells, correlated well with the color of cells in the tissue. Chemical imaging using single-cells as voxels reflects the spatial distribution of biochemical differences within a tissue without the distortion stemming from sampling multiple cells within the laser focal spot. Microsampling by laser ablation also has the benefit of enabling the analysis of very small cell populations for biochemical heterogeneity. For example, with a similar to 30 mu m ablation spot we were able to analyze 3-4 achlorophyllous cells within an oil gland on a sour orange (Citrus aurantium) leaf. To explore cell-to-cell variations within and between tissues, multivariate statistical analysis on LAESI-MS data from epidermal cells of an A. cepa bulb and a C. aurantium leaf and from human buccal epithelial cell populations was performed using the method of orthogonal projections to latent structures discriminant analysis (OPLS-DA). The OPLS-DA analysis of mass spectra, containing over 300 peaks each, provided guidance in identifying a small number of metabolites most responsible for the variance between the cell populations. These metabolites can be viewed as promising candidates for biomarkers that, however, require further verification.

However, this objective becomes contentious when perceived to be in conflict with the conservation of rare or endemic species. We monitored the effects of two forest restoration treatments, spring- vs fall-prescribed burning, on the density of the endemic Tiny Canyon mountainsnail (Oreohelix sp.). We used a randomized block design with three replicates of each of the treatments and controls, and analyzed our data using multivariate repeated measures analysis of variance. We conducted pre-treatment surveys for mountainsnails and post-treatment surveys at three time periods: within two weeks of the treatment, the next snail season following the treatment (next spring or fall), and one year following the treatments. We did not detect any statistically significant differences in mountainsnail densities as a result of the spring-burn or fall-burn treatments, time of survey, or treatment x time interaction. The burns resulted in a fine-scale mosaic that included un-burned and lightly burned areas that acted as refuge for mountainsnails. We recommend that the application of prescribed burning as a restoration treatment within mountainsnail habitat be conducted under prescriptions that create a mosaic of burn conditions, including small unburned areas, and that prescribed fire return intervals mimic natural fire intervals (10-40 years).

The role of gamma delta T cells in innate responses against infection with foot-and-mouth disease virus was analyzed on consecutive 5 d following infection. Before infection, bovine WC1(+) gamma delta T cells expressed a nonactivated phenotype relative to CD62L, CD45RO, and CD25 expression and did not produce IFN-gamma ex vivo. Additionally, CD335 expression was lacking and no spontaneous target cell lysis could be detected in vitro, although perforin was detectable at a very low level. MHC class II and CD13 expression were also lacking. Following infection with foot-and-mouth disease virus, expression of CD62L and CD45RO was greatly reduced on WC1(+) gamma delta T cells, and unexpectedly, CD45RO expression did not recover. A transient increase in expression of CD25 correlated with production of IFN-gamma. Expression of CD335 and production of perforin were detected on a subset of gamma delta T cells, and this correlated with an increased spontaneous killing of xenogeneic target cells. Furthermore, increased MHC class II expression was detected on WC1(+) gamma delta T cells, and these cells processed protein Ags. These activities are rapidly induced, within 3 d, and wane by 5 d following infection. All of these functions, NK-like killing, Ag processing, and IFN-gamma production, have been demonstrated for these cells in various species. However, these results are unique in that all these functions are detected in the same samples of WC1(+) gamma delta T cells, suggesting a pivotal role of these cells in controlling virus infection.

TI Soil water availability and microsite mediate fungal and bacterial phospholipid fatty acid biomarker abundances in Mojave Desert soils exposed to elevated atmospheric CO2 SO JOURNAL OF GEOPHYSICAL RESEARCH-BIOGEOSCIENCES LA English DT Article ID MICROBIAL COMMUNITY STRUCTURE; CARBON-DIOXIDE ENRICHMENT; NITROGEN DYNAMICS; CLIMATE-CHANGE; UTILIZATION PATTERNS; ECOSYSTEM FUNCTION; TALLGRASS PRAIRIE; N-MINERALIZATION; GRASSLAND SOILS; ARID ECOSYSTEM AB Changes in the rates of nitrogen (N) cycling, microbial carbon (C) substrate use, and extracellular enzyme activities in a Mojave Desert ecosystem exposed to elevated atmospheric CO2 suggest shifts in the size and/or functional characteristics of microbial assemblages in two dominant soil microsites: plant interspaces and under the dominant shrub Larrea tridentata. We used ester-linked phospholipid fatty acid (PLFA) biomarkers as a proxy for microbial biomass to quantify spatial and temporal differences in soil microbial communities from February 2003 to May 2005. Further, we used the C-13 signature of the fossil CO2 source for elevated CO2 plots to trace recent plant C inputs into soil organic matter (SOM) and broad microbial groups using delta C-13 (parts per thousand). Differences between individual delta C-13(PLFA) and delta C-13(SOM) for fungal biomarkers indicated active metabolism of newer C in elevated CO2 soils. Total PLFA-C was greater in shrub microsites compared to plant interspaces, and CO2 treatment differences within microsites increased under higher soil water availability. Total, fungal, and bacterial PLFA-C increased with decreasing soil volumetric water content (VWC) in both microsites, suggesting general adaptations to xeric desert conditions. Increases in fungal-to-bacterial PLFA-C ratio with decreasing VWC reflected functional group-specific responses to changing soil water availability. While temporal and spatial extremes in resource availability in desert ecosystems contribute to the difficulty in identifying common trends or mechanisms driving microbial responses in less extreme environments, we found that soil water availability and soil microsite interacted with elevated CO2 to shift fungal and bacterial biomarker abundances in Mojave Desert soils.

These data were compared to mating frequencies in sentinel females placed in the field during the first three weeks of May. Under colony conditions weak illumination in the final hour of the scotophase resulted in similar to 90% mating on the first day after eclosion; significantly greater mating compared to complete darkness throughout the scotophase, weak illumination throughout the scotophase, or weak illumination for both the first and last hour of the scotophase. In an environmental chamber programmed to simulate spring conditions, little mating occurred on the first night after eclosion and three nights were required for more than 50% of the females to mate. There was no difference in mating frequency with between moths exposed to complete darkness throughout the scotophase and those provided with weak illumination in the last half hour of the scotophase or throughout the scotophase. This delay in age of first mating was consistent with field observations with sentinel females at May in the central San Joaquin Valley. The authors conclude that, along with greater longevity and later oviposition, first mating occurs at a later age in spring conditions compared to summer conditions in this species. Planned studies of the effect of delayed mating in first and second flights will need to take these factors into account.

Makino, also known as jiaogulan, has been shown to have antioxidant, antiproliferative, and anti-inflammatory activities. Flavonoid is considered a major contributor for these beneficial effects. To obtain chemical patterns of flavonoids in G. pentaphyllum of different genotypes (di- versus tetraploids) and different parts (leaf versus whole plant) of plants, the extraction condition was optimized and a fingerprinting approach was established by means of high-performance liquid chromatography coupled with diode array detection and mass spectrometry (HPLC-DAD-MS). Eight flavonoids were identified, among which rutin and quercetin were quantified. The highest levels of rutin and quercetin were 23.03 and 12.10 mg/g, respectively, observed in the diploid leaf sample 2L3 and 2L2, while the lowest levels of rutin and quercetin were 1.92 and 0.25 mg/g in the tetraploid whole-plant sample 4W3. The chemical patterns were further analyzed by similarity calculation and principal component analysis (PCA). Seven common characteristic peaks were found in all of the tested samples. Flavonoid patterns of tetraploids were significantly different from those of diploids, whereas different parts of plants showed less difference. The flavonoid pattern of the diploid leaf sample was most similar to that of the reference botanical G. pentaphyllum. The combination of chromatographic fingerprint and quantification analysis could be used for quality assessment of G. pentaphyllum and its derived nutraceutical products.

TI Receptor specificity of subtype H1 influenza A viruses isolated from swine and humans in the United States SO VIROLOGY LA English DT Article DE Influenza; Swine; Human; H1 hemagglutinin; Receptor; Binding; Sialic acid ID EMBRYONATED CHICKEN EGGS; BINDING PROPERTIES; GENETIC-CHARACTERIZATION; MEDIATED SELECTION; SEVERE DISEASE; H3N2 VIRUSES; HOST-CELL; HEMAGGLUTININ; PIGS; ORIGIN AB The evolution of classical swine influenza viruses receptor specificity preceding the emergence of the 2009 H1N1 pandemic virus was analyzed in glycan microarrays. Classical swine influenza viruses from the alpha, beta, and gamma antigenic clusters isolated between 1945 and 2009 revealed a binding profile very similar to that of 2009 pandemic H1N1 viruses, with selectivity for alpha 2-6-linked sialosides and very limited binding to alpha 2-3 sialosides. Despite considerable genetic divergence, the 'human-like' H1N1 viruses circulating in swine retained strong binding preference for alpha 2-6 sialylated glycans. Interspecies transmission of H1N1 influenza viruses from swine to humans or from humans to swine has not driven selection of viruses with distinct novel receptor binding specificities. Classical swine and human seasonal H1N1 influenza viruses have conserved specificity for similar alpha 2-6-sialoside receptors in spite of long term circulation in separate hosts, suggesting that humans and swine impose analogous selection pressures on'the evolution of receptor binding function.

TI Effects of the insect growth regulator, novaluron on immature alfalfa leafcutting bees, Megachile rotundata SO JOURNAL OF INSECT SCIENCE LA English DT Article DE pollinator; alfalfa seed; Rimon; egg mortality ID HYMENOPTERA-MEGACHILIDAE; PESTICIDES; POPULATION; EMERGENCE; PACIFICA AB Alfalfa leafcutting bees, Megachile rotundata F. (Hymenoptera: Megachilidae), are the most common pollinators of alfalfa in the Pacific Northwest. Reports from users of M. rotundata in Idaho, Utah and Colorado have indicated exceptionally poor bee return from fields treated with novaluron to control Lygus spp. Our goal was to evaluate novaluron toxicity to immature M. rotundata using two different possible mechanisms of exposure. One goal was to assess immature mortality via treating nectar-pollen provisions and adults with novaluron. Immature M. rotundata mortality in all novaluron provision dosing treatments was significantly higher than the water or blank controls, providing evidence that novaluron is toxic to progeny in nest cells. The mean cumulative frequency showed that more eggs and 1st-2nd instars died compared to older instars. Female M. rotundata nested similarly in field cages during the field cage experiment; however, there was greater immature mortality in cages where females were fed sugar-water + novaluron compared to sugar-water only. Although females provided adequate provisions, there was a low percentage of egg hatch and larval development when females ingested novaluron before mating and nesting. Novaluron was also present in egg provision of bees collecting resources from novaluron-sprayed plants. At least 84% of progeny died when the females were allowed to mate and nest 24 hours after a novaluron application. Novaluron could be contributing to poor bee return in alfalfa grown for seed. Timely insecticide applications to suppress Lygus spp. is an important consideration to improve ongoing bee health. C1 [Hodgson, Erin W.] Iowa State Univ, Dept Entomol, Ames, IA 50011 USA.

This is the first evidence of IIV6 infection in P. vandinei that caused both patent and sub-lethal infections in larvae and adults. Mortality rates were determined to be similar to 30% when virus inoculum was injected into larvae or adults. Adults injected with virus showed dramatically altered behavior; injected beetles were not observed feeding or mating compared with adults injected with buffer or adults that were not injected. Tissue collected from infected adults resulted in infection when injected into healthy adults, as confirmed with PCR. PCR also confirmed that frass of infected larvae and adults contained virus, and when reconstituted frass from infected individuals was injected into healthy adults or larvae they become infected. Healthy adults could be infected by coming into contact with soil or plant material that had been exposed to infected adults as much as two weeks prior to introduction of nonvirus exposed adults. Although relatively low mortality resulted when adults or larvae were injected with the virus, the demonstration of horizontal transmission, potentially through frass of infected individuals, identifies a mode of transmission that may be exploited as a potential management tool to reduce P. vandinei.

We now confirm that this pathogen is capable of synthesizing a much broader spectrum of host glycolipid/glycoprotein mimics within its LOS. P blood group and paragloboside (lacto-N-neotetraose) antigen mimicry is exhibited by RM1221, a strain isolated from a poultry source. RM1503, a gastroenteritis-associated strain, expresses lacto-N-biose and sialyl-Lewis c units, the latter known as the pancreatic tumor-associated antigen, DU-PAN-2 (or LSTa). C. jejuni GC149, a Guillain-Barre ' syndrome-associated strain, expresses an unusual sialic acid-containing hybrid oligosaccharide with similarity to both ganglio and P-k antigens and can, through phase variation of its LOS biosynthesis genes, display GT1a or GD3 ganglioside mimics. We show that the sialyltransferase CstII and the galactosyltransferase CgtD are involved in the synthesis of multiple mimic types, with LOS structural diversity achieved through evolving allelic substrate specificity.

Coupling great interest in this species as a research model with the need for genetic improvement of aquaculture production efficiency traits justifies the continued development of genomics research resources. Many quantitative trait loci (QTL) have been identified for production and life-history traits in rainbow trout. An integrated physical and genetic map is needed to facilitate fine mapping of QTL and the selection of positional candidate genes for incorporation in marker-assisted selection (MAS) programs for improving rainbow trout aquaculture production. Results: The first generation integrated map of the rainbow trout genome is composed of 238 BAC contigs anchored to chromosomes of the genetic map. It covers more than 10% of the genome across segments from all 29 chromosomes. Anchoring of 203 contigs to chromosomes of the National Center for Cool and Cold Water Aquaculture (NCCCWA) genetic map was achieved through mapping of 288 genetic markers derived from BAC end sequences (BES), screening of the BAC library with previously mapped markers and matching of SNPs with BES reads. In addition, 35 contigs were anchored to linkage groups of the INRA (French National Institute of Agricultural Research) genetic map through markers that were not informative for linkage analysis in the NCCCWA mapping panel. The ratio of physical to genetic linkage distances varied substantially among chromosomes and BAC contigs with an average of 3,033 Kb/cM. Conclusions: The integrated map described here provides a framework for a robust composite genome map for rainbow trout. This resource is needed for genomic analyses in this research model and economically important species and will facilitate comparative genome mapping with other salmonids and with model fish species. This resource will also facilitate efforts to assemble a whole-genome reference sequence for rainbow trout.

Influence mechanisms and combating strategies towards them have similarities to some extent. Impacts of air pollution and climate change have long been studied under IUFRO Research Group 7.01 and state of the art findings are presented at biannual meetings. Monitoring, modelling, assessment of multiple stressors, ecophysiology, and nutrient cycles have been thoroughly studied aspects of climate change and air pollution research for a long time under the umbrella of IUFRO RG 7.01. Recently, social and economic issues together with water relations are gaining more attention in parallel with science requirements on adaptation. In this paper, we summarise the main research needs emphasized at the recent 24th IUFRO RG 7.01 Conference titled "Adaptation of Forest Ecosystems to Air Pollution and Climate Change". One important conclusion of the conference was the need for information on nutritional status of forest stands for sustainable forest management. It has been suggested to maintain long-term monitoring programs and to account for the effects of extreme years, and past and present management practices. Long-term monitoring can also help to understand the effects of forestry treatments on the nutrient and water budgets of the ecosystems which may enable to improve management practices like water saving silviculture.

Their general objective is to characterize the air pollution and its potential effects upon forest ecosystems' status and biodiversity in close connection with climatic changes. Two monitoring networks were placed in selected forest ecosystems for each LTER site (11 plots in Retezat and 22 plots in Bucegi - Piatra Craiului, respectively). Both in Retezat and Bucegi - Piatra Craiului Mts, the distribution of mean ozone (O(3)) concentrations are significantly correlated with altitude. The location (plot) has a significant influence on ozone concentration and in some cases the exposure period along the growing season has an influence. Ambient ozone (O3) and ammonia (NH(3)) concentrations were below toxicity levels for forest trees, their health status (crown condition) and volume growth being insignificantly affected. More than 45% of the rain events were acidic with pH <= 5.5, thus contributing to an increased N deposition on forest stands. In Retezat Mts crown condition was relatively better than in Bucegi - Piatra Craiului Mts. As a consequence, in 2009 European beech (Fagus sylvatica) was the least affected species, with a percentage of damaged trees (crown defoliation higher than 25%) between 8.0% (Retezat) and 9.8% (Bucegi - Piatra Craiului), followed by Norway spruce (Picea abies) with 12.9% (Retezat) and 27.7% (Bucegi - Piatra Craiului). The most affected species was Silver fir (Abies alba) with 31.6% of damaged trees (Bucegi-Piatra Craiului). In the last period, both European beech and conifers (Norway spruce and Silver fir) with high defoliation (damaged trees) had lower annual relative increment than trees with low defoliation (healthy trees). A definite trend regarding rapid environmental modifications is not evident and no significant reduction of biodiversity occurred. In addition, all the vegetation biodiversity components of the forest ecosystems are specific to the stand type's structures and local climate conditions, and no quantifiable consequences of specific air pollutants on ecosystems' diversity occurred.

TI Fatty Acid Alkyl Esters as Solvents: Evaluation of the Kauri-Butanol Value. Comparison to Hydrocarbons, Dimethyl Diesters, and Other Oxygenates SO INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH LA English DT Article ID CORRELATION GAS-CHROMATOGRAPHY; METHYL-ESTERS; VAPOR-PRESSURES; VAPORIZATION ENTHALPIES; CRUDE-OIL; BIODIESEL; BIODEGRADATION; POLYMERIZATION; BIOREMEDIATION AB Esters, most commonly methyl esters, of vegetable oils or animal fats or other lipid feedstocks have found increasing use as an alternative diesel fuel known as biodiesel. However, biodiesel also has good solvent properties, a feature rendered additionally attractive by its biodegradability, low toxicity, and low content of volatile organic compounds. The kauri-butanol (KB) value is a parameter used for describing the solvent strength of a liquid. In this work, the KB values of individual fatty acid alkyl esters were determined. The KB values of fatty esters depend on chain length, including the alcohol moiety, and unsaturation, a phenomenon observed similarly in hydrocarbons. The KB values of fatty acid methyl esters range from well over 100 for short-chain esters to the 40-60 range for C18 esters with a maximum being attained for methyl esters of C(4)-C(5) acids. For the sake of comparison, the KB values of dimethyl diesters and hydrocarbons (alkanes) were also determined as well as those of some standard solvents. Compounds with eight carbons were selected to compare the influence of various functional groups on solvent strength as documented by the KB value. KB values can be determined with good accuracy by reducing the amount of KB solution from 20 to 5 g, thus using correspondingly less solvent sample.

Field trials were conducted over two seasons to determine if the abundance of males and females of three common Frankliniella species, F. occidentalis (Pergande), F. tritici (Fitch) and F. bispinosa (Morgan), their larvae, and a key predator, Orius insidiosus (Say) (Hemiptera: Anthocoridae) were affected by host plant type and plant nutritional quality. Two host plants, pepper, Capsicum annuum L. (Solanales: Solanaceae) and tomato, Solanum lycopersicum L. that vary in suitability for these species were examined, and their nutritional quality was manipulated by applying three levels of nitrogen fertilization (101 kg/ha, 202 kg/ha, 404 kg/ha). F. occidentalis females were more abundant in pepper than in tomato, but males did not show a differential response. Both sexes of F. tritici and F. bispinosa were more abundant in tomato than in pepper. Larval thrips were more abundant in pepper than in tomato. Likewise, O. insidiosus females and nymphs were more abundant in pepper than in tomato. Only F. occidentalis females showed a distinct response to nitrogen fertilization, with abundance increasing with fertilization. These results show that host plant utilization patterns vary among Frankliniella spp. and should not be generalized from results of the intensively studied F. occidentalis. Given the different pest status of these species and their differential abundance in pepper and tomato, it is critical that scouting programs include species identifications for proper management.

TI Insertion of miniature subterminal inverted repeat-like elements in diapause-regulated genes in the Colorado potato beetle, Leptinotarsa decemlineata (Coleoptera: Chrysomelidae) SO EUROPEAN JOURNAL OF ENTOMOLOGY LA English DT Article DE Chrysomelidae; Coleoptera; Leptinotarsa juncta; transposons ID DNA-MEDIATED TRANSPOSITION; TRANSPOSABLE ELEMENTS; CAENORHABDITIS-ELEGANS; HUMAN GENOME; RICE GENES; FAMILY; MAIZE; AMPLIFICATION; STOWAWAY; TOURIST AB Determining the genomic structure of diapause-associated transcripts (DAT) -2 and -3 led to the isolation of four novel miniature subterminal inverted repeat-like elements (MSITE): Mild-1, -2, -3 and -4. Mild-1 a is inserted within the first intron of diapause protein-1. Mild-1a is 284 bp in length, has a 14 bp target site duplication and three sets of subterminal inverted repeats. The second element, Mild-2a, is inserted within the 3' terminus of Mild-1a. Mild-2a is 29 bp long with a 3 bp target site duplication and one set of subterminal inverted repeats. Using primers based on Mild-1, genomic clones were developed leading to the isolation of Mild-3a. Mild-3a shares 60% identity with Mild-1a, is 253 bp long, has a 9 bp target site duplication and has one set of subterminal inverted repeats. Mild-4a is inserted within the first intron of DAT-2 and is 227 bp in length with a 12 bp target site duplication. Mild-4a appears to be an intermediate form between a miniature inverted repeat transposable element (MITE) and a MSITE because the 5' inverted repeat is terminal (i.e., adjacent to the target site duplication) as in MITEs, but the 3' inverted repeat is separated (in this case, by 33 bp) from the 3' target site duplication as in MSITEs. The target site duplications of Mild-1, -3 and -4 families share a common conserved core of AATTT. All of the transposable elements are AT rich and are able to form hairpin structures. Within the promoter legion of DAT-3 is a 163 bp sequence (Mild-1b) that shares 77% identity to the 3 terminus of Mild-1a. Mild-4a has identity to 25 and 53 bp regions within the promoter of the juvenile hormone esterase B gene. Southern blot analysis revealed the presence of Mild-1 and -3 elements in both Leptinotarsa decemlineata and Leptinotarsa juncta indicating that these elements are ancestral to the L. decemlineata, L. juncta separation.

Some ants, such as the fire ant Solenopsis invicta, are also major pests. Here, we present a draft genome of S. invicta, assembled from Roche 454 and Illumina sequencing reads obtained from a focal haploid male and his brothers. We used comparative genomic methods to obtain insight into the unique features of the S. invicta genome. For example, we found that this genome harbors four adjacent copies of vitellogenin. A phylogenetic analysis revealed that an ancestral vitellogenin gene first underwent a duplication that was followed by possibly independent duplications of each of the daughter vitellogenins. The vitellogenin genes have undergone subfunctionalization with queen-and worker-specific expression, possibly reflecting differential selection acting on the queen and worker castes. Additionally, we identified more than 400 putative olfactory receptors of which at least 297 are intact. This represents the largest repertoire reported so far in insects. S. invicta also harbors an expansion of a specific family of lipid-processing genes, two putative orthologs to the transformer/feminizer sex differentiation gene, a functional DNA methylation system, and a single putative telomerase ortholog. EST data indicate that this S. invicta telomerase ortholog has at least four spliceforms that differ in their use of two sets of mutually exclusive exons. Some of these and other unique aspects of the fire ant genome are likely linked to the complex social behavior of this species.

Diptera includes species known for their ubiquity (Musca domestica house fly), their role as pests (Anopheles gambiae malaria mosquito), and their value as model organisms across the biological sciences (Drosophila melanogaster). A resolved phylogeny for flies provides a framework for genomic, developmental, and evolutionary studies by facilitating comparisons across model organisms, yet recent research has suggested that fly relationships have been obscured by multiple episodes of rapid diversification. We provide a phylogenomic estimate of fly relationships based on molecules and morphology from 149 of 157 families, including 30 kb from 14 nuclear loci and complete mitochondrial genomes combined with 371 morphological characters. Multiple analyses show support for traditional groups (Brachycera, Cyclorrhapha, and Schizophora) and corroborate contentious findings, such as the anomalous Deuterophlebiidae as the sister group to all remaining Diptera. Our findings reveal that the closest relatives of the Drosophilidae are highly modified parasites (including the wingless Braulidae) of bees and other insects. Furthermore, we use micro-RNAs to resolve a node with implications for the evolution of embryonic development in Diptera. We demonstrate that flies experienced three episodes of rapid radiation-lower Diptera (220 Ma), lower Brachycera (180 Ma), and Schizophora (65 Ma)-and a number of life history transitions to hematophagy, phytophagy, and parasitism in the history of fly evolution over 260 million y.

The objective of this study was to determine if parasitism of fish affected vaccine efficacy. Antibody level, hematology and survival of Nile tilapia vaccinated with a modified S. iniae bacterin were compared among non-parasitized fish, fish parasitized by Trichodina heterodentata and Gyrodactylus cichlidarum, and fish parasitized by T. heterodentata, G. cichlidarum and Ichthyophthirius multifiliis (Ich). Among vaccinated fish, fish free from parasites (Trichodina, Gyrodactylus and Ich) had the highest antibody level (0.43, SE = 0.14). Significantly (p<0.05) lower anti-S. iniae antibody was noted in parasitized vaccinated fish (0.30, SE = 0.08). Among the vaccinated treatments, fish parasitized by Trichodina, Gyrodactylus and Ich showed the lowest survival (80.0%, SE = 10.0), significantly (p<0.05) lower than vaccinated fish free from parasites (97.5%, SE = 2.5) or parasitized by Trichodina and Gyrodactylus (95.0%, SE = 5.0). Following challenge with S. iniae, non-vaccinated fish free from parasites showed the higher survival (47.5%, SE = 2.5) than non-vaccinated fish parasitized by Trichodina and Gyrodactylus (37.5%, SE = 2.5). Non-vaccinated fish parasitized by all 3 parasites showed the lowest survival (27.5%. SE = 2.5) post challenge. Relative percent survival (RPS) demonstrated a decrease in vaccine performance for the group of fish that were parasitized with Trichodina and Gyrodactylus and Ich. RPS was 72% compared to 95 and 92%, respectively, in the other vaccinated treatments following challenge. This study demonstrated a reduction in vaccine performance in parasitized tilapia and highlights the importance of monitoring or controlling parasite levels in the aquaculture setting to optimize vaccine efficacy.

Measurements of water vapor transmission rate (WVTR) were performed by a modification of the wet cup method described by ASTM E 96-95, indicating that membranes with 10% nanocrystalline cellulose, prepared using a sulfuric acid, exhibited the lowest permeability value of 174 g mil/h m(2) among the composite films studied. Both the acacia and the softwood kraft pulp fibers when used for xylan film formation exhibited higher water vapor transmission rates at addition levels of 50% and no improvement at lower levels of 5% and 10%, in comparison to control xylan films. Reinforcement of xylan with hydrochloric acid made nanocrystalline cellulose yielded films that showed a reduction, in water transmission but the reduction was not as significant as with the reinforcement of xylan with sulfuric nanocrystalline cellulose. The results showed that xylan films reinforced with 10% sulfuric nanocrystalline cellulose exhibited reductions in water transmission rates of 362%, 62% and 61% over films prepared with 10% softwood kraft fibers, 10% acacia fiber and 10% hydrochloric acid prepared nanocrystalline cellulose, respectively. The morphology of the resulting nanocomposite films was examined by SEM and AFM which showed that control films containing xylan and sorbitol had a more open structure as compared to xylan-sorbitol films containing sulfuric nanocrystalline cellulose. The results from FT-IR suggested strong interactions occurred between the nanocrystalline cellulose and the matrix. (C) 2011 Elsevier Ltd. All rights reserved.

However, endogenous enzymes within salmon vary with spawning maturity, and must be controlled in the raw material to ensure a consistent hydrolysate. Differences in proteolytic activities were found among tissue groups (fillets, heads, livers and viscera) in male and female adult pink salmon (Oncorhynchus gorbuscha) harvested at three different levels of spawning maturity. Changes in protease levels may have implications for processing hydrolysates when pink salmon of different maturity levels are used.

Recently, this prairie grass has received increased attention as a potential biomass energy crop. Little is known about the arthropod community affecting switchgrass grown under either managed or minimally managed conditions. This information is important for characterizing the arthropods associated with switchgrass and developing appropriate management strategies for potential pests. The objectives of this research were to identify the arthropods associated with switchgrass in Nebraska and to document the seasonal abundance of selected arthropods. In 2007 and 2008, arthropods were sampled from May through October using vacuum samples, soil cores, pitfall traps, and yellow sticky traps. Samples were collected from switchgrass stands managed for biomass production and from native switchgrass at Nine-Mile Prairie in Lancaster County, NE. Thysanoptera and Hymenoptera comprised 60% of arthropods collected. Leafhoppers, grasshoppers, grass flies, and wireworms were the most abundant potential pests, whereas beneficial arthropods included ants, rove beetles, ground beetles, parasitoid wasps, and spiders. This research provides important baseline information on the arthropods associated with switchgrass in the central Great Plains.

Traps baited with this sex attractant and maintained through the growing season captured D. terrapictalis primarily in May in Umatilla County, Oregon, and in June and early July in eastern Washington. Small numbers of D. diffusa were present also in these traps, largely coincident in time with D. terrapictalis captured. This is the first demonstration of a sex attractant for D. terrapictalis and confirms the presence of D. diffusa in the states of Oregon and Washington through the identification of trapped moths.

Chronic over browsing and biodiversity collapse in a forest understory in Pennsylvania: results from a 60-year-old deer exclusion plot. J Torrey Bot. Soc. 138: 220-224. 2011.-We evaluated the impact of chronic deer over browsing on the diversity and abundance of understory forbs and shrubs within a forest stand in the Allegheny High Plateau Region of Pennsylvania by comparing vegetation inside a 60-year-old exclosure to vegetation within an adjacent reference site. This is the oldest known exclosure in the Eastern Deciduous Forest. Browsing caused the formation of an extremely low diversity herbaceous understory dominated by a single fern species, caused the local extirpation of shrubs, and drove forbs to extremely low abundance (< 0.2% cover m(-2) vs. 43% inside the exclosure). Our results confirm previous findings that demonstrate that browsing has caused 60-80% declines in herb and shrub richness regionally. Because many of these species have low dispersal and reproductive rates, we predict long-term legacy effects if deer numbers are ever reduced. Our results combined with other studies provide information on shrub and herb abundance in the absence of browsing that may serve as a baseline to compare potential community recovery in the future.

Rootstock, tree variety, and cultural management practice were significantly associated with the presence and extent of dogwood borer infestation. In West Virginia, infestation was significantly greater on trees planted on M. 26 rootstock compared with M. 7 rootstock, and on trees fitted with tree guards compared with other trunk treatments. In Virginia, the proportion of infested trees was significantly greater for 'Idared' tree varieties compared with 'Buckeye Gala', and on trees fitted with tree guards compared with other trunk treatments. Median polishing technique was used to separate variability in the infestation data into large-scale variation (trend) induced mainly by treatments and small-scale variation. Variography was used to study the median-polished residuals of infestation that represent the small-scale variation. The results of variogram analysis of the median-polished residuals indicated that there were moderate to high degrees of aggregation in dogwood borer infestations on neighboring apple trees (Malus domestica Borkh.) with ranges of spatial autocorrelation from 2.8 to 17.0 m. The spatial patterns of the aggregation of infestation in the West Virginia and Virginia orchards were best described by the spherical and exponential semiovariogram models, respectively. Interpolated surface maps of the median-polished residuals revealed local hot spots, which were generally more prevalent within tree guard treatments, and were typically found where dogwood borer infestations originated. Results are discussed in relation to the sampling and management of dogwood borer larvae. C1 [Frank, Daniel L.; Bergh, J.

The substrate at these sites, consisting of waste hay mixed with bovine manure and urine, provided an excellent developmental habitat for immature stable flies. Stable flies were the most frequently collected fly emerging from these sites with a yearly average of 1,581 emerging per square meter. Stable fly emergence from these sites began in early May (235 annual accumulated Day-Degree 10 degrees C [DD10]), peaked in late June and early July (400-900 DD10) and then dropped to very low levels in late July (>900 DD10). The temporal pattern of stable fly emergence from the hay feeding sites differed from that of adult populations measured with sticky traps. Adult populations increased in the spring before significant emergence from the hay feeding sites was observed, dipped in midsummer soon after the hay feeding sites became nonproductive, and then rebounded in the late summer when emergence from the hay feeding sites was very low. The drop in productivity of the hay feeding sites appeared to be because of endogenous factors associated with decomposition of the substrate rather than temperature or precipitation. Winter hay feeding sites appear to be primary sources of stable flies during the early summer, however, they are not responsible for late summer and fall stable fly populations. Overall, the inner most 2-m annulus of the hay feeding sites was the most productive, however, spatial variation among sites was observed. The sex ratio of emerging flies did not differ from 1:1 and the temporal pattern of emergence was similar for males and females. Although several other species of flies were collected emerging from the hay feeding site substrate, house flies (Musca domestica L.) were notably absent. C1 [Taylor, D. B.; Berkebile, D.

States have kept county-level records on the locations of beetle outbreaks for the past 50 yr. This study determined how accurately patterns of county-level infestations in preceding years could predict infestation occurrence in the current year and if there were emergent patterns that correlated strongly with beetle outbreaks. A variety of methods were tested as infestation predictors, including quantification of either the exact locations of infested grid cells during one or two preceding years, or the neighborhood infestation intensity (number of infested cells in a neighborhood) in these years. The methods had similar predictive abilities, but the simpler methods performed somewhat better than the more complex ones. The factors most correlated with infestations in future years were infestation in the current year and the number of surrounding counties that were infested. Infestation history helped to predict the probability of future infestations in a region, but county-level patterns alone left much of the year-to-year variability unexplained.

Thus, this 5-yr study was conducted to determine parasitism and predation of sentinel and natural occurring Euschistus servus (Say) and Nezara viridula (L.) egg masses in farmscapes in Georgia. A variety of parasitoids including six scelionids, Trissolcus basalis (Wollaston), T. brochymenae (Ashmead), T. euschisti (Ashmead), T. thyantae Ashmead, Telenomus podisi Ashmead, and Gyron obesum Masner, and one encyrtid, Ooencyrtus spp., was recovered from E. servus and N. viridula eggs, but overall the greatest diversity of parasitoids emerged from stink bug eggs in corn. Only T. basalis and T. podisi parasitized both N. viridula and E. servus eggs in all three crops over all farmscapes. A wide variety of predators, including Orius insidiosus (Say), Geocoris punctipes (Say), G. uliginosus (Say), Coccinella septempunctata (L.), Hippodamia convergens Guerin-Meneville, Harmonia axyridis (Pallas), Coleomegilla maculata (De Geer), Scymnus loewii Mulsant, Scymnus ardelio Horn, and Solenopsis invicta Buren, preyed on stink bug eggs in each crop. When differences were detected, generally percent parasitization per egg mass was higher than predation in corn, and percent predation was higher than parasitization in peanut. Overall, percent predation per egg mass was higher than parasitization in cotton, but on one occasion percent parasitization was higher than predation in cotton associated with corn. Seasonal occurrence and abundance of natural enemies, levels of parasitization and predation of stink bug eggs, and percent egg predation by sucking and chewing predators indicated that natural enemies of stink bug eggs disperses from crop to crop in the farmscapes.

ID SPECIES COMPLEX HYMENOPTERA; BACTROCERA-OLEAE DIPTERA; CONCOLOR HYMENOPTERA; DIACHASMIMORPHA-LONGICAUDATA; BAIT GF-120; POPULATIONS; PARASITOIDS; TRYPETIDAE; RELEASE; AFRICA AB The larval parasitoid, Psyttalia humilis (Silvestri), reared on Mediterranean fruit fly, Ceratitis capitata (Weidemann), by USDA-APHIS-PPQ, San Miguel Petapa, Guatemala was imported into California for biological control of olive fruit fly, Bactrocera oleae (Rossi). This study reports the results of field releases and recovery of P. humilis in California, and laboratory investigations to determine the effects of food provision, high temperature, and insecticidal bait spray on the parasitoid's survival and fecundity. Parasitoids (3,613-7,823) were released in Orland, San Juan Bautista, Cayucos, Sylmar, Santa Barbara, and San Diego during October through December 2006. Mean daily temperatures at the release sites ranged from 10.7 degrees C in Orland to 20.9 degrees C in San Juan Bautista. The lowest (0.5) and highest (29.7) mean number of adult B. oleae per day per trap was captured in Orland and Sylmar, while the lowest (0.01) and highest (2.21) number of third instar larvae per fruit was collected on 11 December in Orland and on 5 October in San Diego in prerelease samples, respectively. Parasitoids were recovered from all release sites, the lowest (0.3%) and highest (100%) parasitism occurred on 25 January in Sylmar and on 26 October in Cayucos, respectively. At 24 degrees C, parasitoids reared from B. oleae larvae survived 36 d on honey, 31 d on orange juice, and 28 d on honeydew, which was significantly longer than on cut olive fruit (8 d) or without food (11 d), but was similar to those reared from C. capitata larvae under the same food conditions. Under a high diurnal temperature regime (18.3-35 degrees C) reflecting the summer olive growing conditions in the California Central Valley, the parasitoids survived <5 d when no food or only water was provided. Its longevity and life-time fecundity significantly increased by provision of honey or honeydew. There was no difference in the parasitoid's longevity between females and males or between food and sexes. Percent mortality of parasitoid adults was not significantly affected by the exposure to insecticidal fruit fly bait (GF-120) in four different types of choice tests with artificial honeydew and GF-120.

TI Laboratory Studies of Variations in Feeding Behaviors Among Lygus hesperus (Hemiptera: Miridae) of Different Gender and Reproductive States SO ENVIRONMENTAL ENTOMOLOGY LA English DT Article DE western tarnished plant bug; cotton; Gossypium; Lygus; feeding behavior ID TARNISHED PLANT BUG; OVIPOSITION BEHAVIOR; COTTON PLANTS; HETEROPTERA; ABSCISSION; KNIGHT; GROWTH; FLIGHT AB Lygus hesperus Knight (Hemiptera: Miridae) is a key pest of cotton (Gossypium spp.) in the western United States that injures floral buds (squares) and developing fruit (bolls). Levels of Lygus-induced damage to cotton can vary by Lygus ages or gender, and these variations complicate interpretation of studies designed to elucidate Lygus and cotton interactions. Variations in observed injury may reflect different behaviors among Lygus gender or ages. We compared times allocated to feeding and trivial movement between male and female adult L. hesperus of different reproductive states: prereproductive, reproductive and mated, and reproductive and unmated. Prereproductive adults exhibited less trivial movement and spent more time stylet-probing compared with reproductive unmated and mated adults. Mated females stylet-probed more times than other classes of adults, whereas mated and unmated reproductive females exhibited more test probes (<= 10 s duration) than prereproductive females. Reproductive females probed the anther region of squares less than prereproductive females. Instead, reproductive females tended to stylet-probe squares below the bracts, which is also where they oviposited. Each oviposition event was preceded by a short duration stylet-probe at the oviposition location. Unmated reproductive males exhibited more test probes but fewer ingestion probes (>1 min) compared with prereproductive and mated males. These results indicate a pattern in which prereproductive adults are less active and feed more compared with reproductive adults, but behaviors vary among reproductive adults of different gender and mating states. We propose that differences in behaviors exhibited among adult L. hesperus are related to the different requirements imposed by mate seeking, mate attraction, and oviposition. C1 [Cooper, W.

Complicating the development of sampling plans for western flower thrips(WFT) Frankliniella occidentalis (Pergande) in greenhouse crops are the facts that they are small, difficult to detect, and attack a variety of crops, which may be grown concurrently within the same greenhouse. Binomial sampling was evaluated as an alternative to sampling plans based on complete enumeration. This work included comparison of incidence-mean models across diverse plant species (impatiens, cucumber, and marigold) to determine the possibility of using a generic model for sampling WFT in mixed crops. Data from laboratory-processed flower samples revealed that infestation rates calculated using a tally threshold of three thrips per flower provided the best estimates of thrips population densities in each tested crop and in the combined crops (composite data set). Distributions of thrips populations were similar across the three plant species, indicating potential for development of a generic sampling plan for mixed floral crops. Practical sampling methods for simple and complex flowers tested in the greenhouse (in situ) were evaluated via construction of binomial count operating characteristic functions. In the case of simple flowers (impatiens), visual inspections provided adequate estimates of thrips infestation rates at a low tally threshold, which ultimately enabled accurate estimation of thrips densities. However, visual inspection and tap-sampling of complex flowers (marigold) provided unreliable results. These findings indicate that use of binomial sampling methods in mixed floral crops will require development of more accurate sampling techniques.

Field observations that males of the hymenopteran parasitoid Pimpla disparis Viereck aggregated on a gypsy moth, Lymantria dispar (L.), host pupa before the emergence of a female led us to hypothesize that these males responded to chemical cues associated with parasitized host pupae. Results of laboratory experiments with wax moth, Galleria mellonella (L.), host pupae suggest that female P. disparis chemically mark the host pupae they have parasitized and that males discern between such pupae and those not parasitized. As males continue to recognize parasitized host pupae throughout the development of the parasitoid, they could exploit not only the females' marker pheromone but possibly also semiochemical, visual, or vibratory cues from the developing parasitoid inside the host pupa, the decaying host, or both. Irrespective, these cues could help males locate parasitized host pupae and time the emergence of a prospective mate.

Plant volatiles included ethyl (E,Z)-2,4-decadienoate (pear ester), (E)-beta-farnesene, (Z)-3-hexenyl acetate, +/- farnesol, and (E)-4,8-dimethyl-1,3,7-nonatriene (DMNT). Male codling moth exhibited upwind behavioral responses to each compound in flight tunnel tests with acetic acid > DMNT > +/- farnesol > (Z)-3-hexenyl acetate > pear ester > (E)-beta-farnesene. In apple orchards, however, only pear ester was an effective lure when used alone with clear pane traps. Choice tests in a flight tunnel with delta traps baited with DMNT plus acetic acid caught significantly more male and females than unbaited traps and significantly more females than DMNT-baited traps. Combining pear ester or DMNT loaded in septa lures with separate vials containing acetic acid significantly increased both male and female moth catch compared with the plant volatile alone, acetic acid alone, and unbaited pane traps in field trials. Similar results were not obtained with the other three plant volatiles. Septum loadings of 1 and 10 mg with either pear ester or DMNT in combination with acetic acid caught similar numbers of moths in orange delta traps. Sixty to 75% of the moths captured in traps baited with DMNT plus acetic acid were females. Moth catches in traps baited with DMNT plus acetic acid were approximate to 40% of catches in similar traps baited with pear ester plus acetic acid. C1 [Knight, A.

TI Diapause Response of Laboratory Reared and Native Lygus hesperus Knight (Hemiptera: Miridae) SO ENVIRONMENTAL ENTOMOLOGY LA English DT Article DE western tarnished plant bug; Lygus hesperus; diapause; rearing ID DIET AB Inconsistencies among results of previous studies on the induction of adult diapause in the western tarnished plant bug, Lygus hesperus Knight, could be either attributed to differences in the criteria being applied to assess diapause status or to differences in the sources of the bugs. To determine the cause of variation and to refine the criteria used to define diapause status, we obtained eggs from adults collected from the field and from long-term laboratory colonies. Concurrent experiments were conducted at two locations. L. hesperus were reared from egg to adulthood under photophases of either 10 or 14 h and at a constant temperature (26.6 degrees C, Shafter, CA; 27.5 degrees C, Maricopa, AZ). Adults were dissected at 10-d posteclosion to measure diapause status using both stringent and relaxed morphological criteria. Under both sets of criteria, offspring of field caught parents were more likely to enter diapause with short day exposure than those offspring from stock colonies. The relaxed criteria appeared appropriate for distinguishing diapause in males, whose reproductive organs can appear undeveloped after mating, although the stringent criteria appeared appropriate for females. Additional analyses were conducted to determine whether extended laboratory rearing influenced other behavioral or physiological traits. Bugs from stock colonies were more likely to mate, and to oviposit as virgins, than were bugs originating from the field. The results demonstrate a pronounced effect of colony rearing on L. hesperus physiology and behavior, and also have led to refinement of the criteria used to assess diapause status. C1 [Brent, C.

Artificial diets using shrimp eggs were developed, and a tier-1 bioassay examining C. maculata development and survival was designed based on those diets. To further measure the artificial diet in a Tier-1 testing system, larvae of C. maculata were fed the diet treated with different concentrations of an inorganic stomach poison, potassium arsenate (PA), or a cysteine protease inhibitor, E-64. The results demonstrated that the testing system was capable of detecting the dietary effects of both substances on the survival and development of C. maculata. With increasing concentrations of PA in the diet, fewer larvae developed to adults, with only 22.7% larvae surviving to the adult stage in the treatment with the highest content of PA (32 mu g/g of diet). Likewise, dose-dependent responses also were found for other life-table parameters of C. maculata. Similar to the assays with PA, the survival rates of C. maculata consistently decreased with increasing E-64 content in the diet. Survival analysis showed that the insects fed E-64 at 50, 150, and 450 mu g/g in the diet had significantly lower survival rates compared with those on the untreated artificial diet. The study presented here describes a robust testing system that will be useful for assessing the potential hazard (or toxicity) effects after dietary exposure of insecticidal compounds produced by GE plants or conventional insecticides on the ladybird predator, C. maculata.

However, the U. S. Environmental Protection Agency has only recently authorized the practice. This commentary explores issues that regulators, industry, and other stakeholders should consider as the use of biotechnology increases and seed mixtures are implemented as a major tactic for IRM. We discuss how block refuges and seed mixtures in transgenic insecticidal corn, Zea mays L., production will influence integrated pest management (IPM) and the evolution of pest resistance. We conclude that seed mixtures will make pest monitoring more difficult and that seed mixtures may make IRM riskier because of larval behavior and greater adoption of insecticidal corn. Conversely, block refuges present a different suite of risks because of adult pest behavior and the lower compliance with IRM rules expected from farmers. It is likely that secondary pests not targeted by the insecticidal corn as well as natural enemies will respond differently to block refuges and seed mixtures.

Thus, it could be useful as a fumigant to decontaminate honey comb between uses. The experiments here are intended to determine the exposure levels required to kill an insect pest and spore forming bee pathogens. Ozone was effective against greater wax moth, Galleria mellonella (L.) (Lepidoptera: Pyralidae), even on naturally infested comb. Neonates and adults were the easiest life stages to kill, requiring only a few hours of exposure, whereas eggs required a 48-h exposure (at 460D920 mg O(3)/m(3)). Two honey bee, Apis mellifera L. (Hymenoptera: Apidae), pathogens, Ascosphaera apis (a fungus that causes chalkbrood) and Paenibacillus larvae (a bacterium that causes American foulbrood), also were killed with ozone. These pathogens required much higher concentrations (3,200 and 8,560 mg O(3)/m(3), respectively) and longer exposure periods (3 d) than needed to control the insects. P. larvae was effectively sterilized only when these conditions were combined with high temperature (50 degrees C) and humidity (>= 75% RH). Thus, ozone shows potential as a fumigant for bee nesting materials, but further research is needed to evaluate its acceptability and efficacy in the field. The need for a reliable method to decontaminate honey bee nesting materials as part of an overall bee health management system is discussed.

Reports of increased incidence of ALS-diseased trees in California prompted surveys in three almond [Prunus dulcis (Mill.) D. A. Webb]-growing regions, from June 2003 to September 2005, to determine insect vector species composition and abundance. For comparison, sampling in and near vineyards in the San Joaquin Valley, California, also was completed. Sampling in or near almond orchards collected > 42,000 Cicadomorpha of which 4.8% were xylem feeders, including 1,912 grass sharpshooter, Draeculacephala minerva Ball; five Xyphon fulgida Nottingham; and a single spittlebug, Philaenus spumarius L. The most abundant vector was D. minerva. Season-long sampling indicated that D. minerva was a year-round resident in and/or near almonds in the Sacramento Valley, but not in the San Joaquin Valley. Similarly, D. minerva was rare in vineyards in the San Joaquin Valley, but was abundant in irrigated pastures near vineyards. D. minerva was most frequently collected along orchard margins, and peak densities were observed in summer, the period of time when bacterial titers are reported to increase in infected trees. Screening of D. minerva for presence of X. fastidiosa found that 1.1% of insects collected near almond orchards and 4.5% of insects collected from pastures tested positive. The X. fastidiosa subspecies and genotype detected in insects collected from orchards matched those collected from ALS-diseased almond trees in the same orchard. Of the few X. fulgida and P. spumarius collected, none tested positive for X. fastidiosa. Results are discussed with respect to X. fastidiosa vector control and detection methods.

Females maintained in groups with males for one week can receive enough sperm for production of female progeny throughout their lives. Volatiles released by emerald ash borer adults feeding on ash foliage increased parasitoid fecundity over ash foliage alone or no stimulus. The temperature at which the parasitoids were reared ranged from 20 to 25 degrees C in a daily cycle; however, raising the daily maximum temperature to 28 degrees C did not affect parasitoid longevity or fecundity. Adult females lived between 12 and 127 d, with an average of 60.8 +/- 4.5 d. Males lived slightly longer, with an average of 66 +/- 4.5 d. The first clutch of eggs was laid when the female was between 2 and 42 d old, with the average preoviposition period lasting 11.4 +/- 1.4 or 19.5 +/- 2.0 d in 2007 and 2009 trials, respectively. A higher proportion of the emerald ash borer larvae were feeding and thus attractive to parasitoids in the 2009 trial, and female S. agrili laid an average of 9.5 +/- 1.0 clutches containing 5.4 +/- 0.2 eggs, for an average of 51.2 eggs per female. Approximately three quarters of the progeny were female. The number of eggs per clutch was significantly greater when deposited on larger emerald ash borer larvae, further highlighting the need for quality larvae in rearing. Chilling S. agrili pupae at 10 degrees C to stockpile them for summer release was not successful; chilling resulted in lower survival and lower fecundity of emerging progeny. Female S. agrili proved capable of attacking emerald ash borer larvae through even the thickest bark of an ash tree that was 30-cm diameter at breast height. Even emerald ash borer larvae that were creating overwintering chambers in the outer sapwood of the tree were successfully attacked, suggesting that S. agrili could be reared on field collected logs infested with emerald ash borer.

Although its preferred hosts are in the Sapotaceae family, several varieties of Citrus, including grapefruit and oranges are listed as alternate hosts. Although Mexican fruit fly, Anastrepha ludens (Loew), is known to be a major pest of Citrus, doubt exists as to the status of Citrus as a breeding host for A. serpentina. To evaluate the host status of commercial Citrus for A. serpentina we compared oviposition and development with that of A. ludens under laboratory conditions with 'Rio Red' grapefruit (Citrus paradisi MacFayden) and 'Valencia' oranges [Citrus sinensis (L.) Osbeck] in different stages of maturity. Both fly species oviposited in early season fruit in which the eggs and larvae died in the fruit albedo. Survival of either species to the adult stage occurred in later season grapefruit. In oranges, no A. serpentina larvae survived compared with 150 A. ludens surviving to adults. Survival on both Citrus species was much lower for A. serpentina, only approximate to 5% of eggs eclosed into larvae in grapefruit compared with approximate to 50% for A. ludens. In oranges approximate to 16% of A. serpentina eggs eclosed compared with approximate to 76% for A. ludens. In grapefruit, only one fourth as many A. serpentina larvae survived to the adult stage compared with A. ludens. Additional experiments were performed in a greenhouse on small, caged trees of la coma (Sideroxylon celastrinum H.B.K.), a Texas species of Sapotaceae. The A. serpentina females readily oviposited into these berries and normal adults emerged. The present low incidence of the adults, coupled with the high mortality during development of the larvae, suggests that Texas citrus is unlikely to support a breeding population of A. serpentina.

Combinedhigh temperature and controlled atmosphere quarantine treatments for phytosanitary fruit pests Macchiademus diplopterus (Distant) (Hemiptera: Lygaeidae) and Phlyctinus callosus (Schoenherr) (Coleoptera: Curculionidae) were investigated to determine the potential of such treatments for quarantine security. Field-collected, aestivating M. diplopterus adults and P. callosus adults were treated using a controlled atmosphere waterbath system. This system simulates the controlled atmosphere temperature treatment system (CATTS) used to control a number of phytosanitary pests in the United States and allows for a rapid assessment of pest response to treatment. Insects were treated under regular air conditions and a controlled atmosphere of 1% oxygen, 15% carbon dioxide in nitrogen, at two ramping heat rates, 12 and 24 degrees C/h. Treatment of both species was more effective under both heating rates when the controlled atmosphere condition was applied. Under these conditions of controlled atmospheres, mortality of P. callosus was greater when the faster heating rate was used, but the opposite was true for M. diplopterus. This could be due to the physiological condition of aestivation contributing to metabolic arrest in response to the stresses being applied during treatment. Results indicate that the potential for the development of CATTS treatments for these phytosanitary pests, particularly P. callosus, is promising. C1 [Johnson, S.

(Coleoptera: Curculionidae), on Astilbe, Euonymus, Heuchera, Rhododendron, Sedum, and Taxus. Insecticide treatments were applied to the soilless substrate of containerized plants. Bioassays were conducted 12 or 13, 26, and 42 d after treatment (DAT) and ran for 7 d; and feeding, mortality, and weight gain or loss by weevils were evaluated. Foliage was removed from test plants and then placed in arenas with adult black vine weevils. The neonicotinoids reduced feeding and weight gain by adult black vine weevils on most plant species with residual activity 42 DAT on some plant species. At 12 DAT, mortality was caused by the three neonicotinoids on Astilbe and by thiamethoxam on Sedum; and at 26 DAT dinotefuran caused mortality on Astilbe. Chlorantraniliprole reduced feeding on Taxus at 12 DAT, with no activity detected in other bioassays. Another set of bioassays was conducted to examine survival and fecundity of adult black vine weevils during prolonged feeding on Heuchera and Taxus systemically treated with dinotefuran or thiamethoxam. Bioassay procedures were similar to those described above, except they ran continuously for 56 d. Prolonged feeding on dinotefuran and thiamethoxam treated Heuchera and Taxus resulted in high mortality of adult black vine weevils and reduced fecundity. These studies show that the systemic activity of neonicotinoids is influenced by plant species and that systemic neonicotinoids have the potential to suppress black vine weevil populations in containerized nursery crops.

Common thyme, cinnamon, and lemongrass oils were equally effective on twospotted spider mite adults showing 85.8-100% mortality at 5 and 10 mu l/liter air at 25 degrees C. At a lower temperature of 15 degrees C, lemongrass and peppermint resulted in >= 90% mortality of adults at 10 mu l/liter air. Only lemongrass was relatively active at 5 mu l/liter air, at 15 degrees C. At 5 degrees C, lemongrass and peppermint caused significantly higher adult mortality than controls but only at 10 mu l/liter air. Common thyme oil showed the highest ovicidal activity at 5 mu l/liter air at 25 degrees C. Among the main components of common thyme and lemongrass oils, citral was lethal to twospotted spider mite adults at all tested temperatures. Carvacrol, thymol, and citral caused the same inhibitory effects on the hatch of twospotted spider mite eggs at 25 degrees C. However, citral was more active than other compounds to twospotted spider mite eggs at 15 degrees C. Therefore, we conclude that citral has the best potential for development as a fumigant against twospotted spider mite on agricultural products harvested late in the growing season.

Rates of flight initiation were slightly lower at lower rearing densities, but they did not differ with age or sex of adults, presence or absence of food in the flight chamber, or duration of food deprivation. Focal adults were less likely to fly when individuals of the opposite sex were present in flight chambers. Presence of the same sex or mixed sexes and numbers of individuals in flight chambers did not affect tendency to fly of focal individuals. Mean time to flight of older beetles (7-20 d old) was less than that of younger beetles (1-4 d old). No young beetles flew during the first 24 h of flight tests. Mean time to flight did not differ with rearing density, sex, presence or absence of food, or duration of food deprivation. Our results indicate that this species is highly dispersive during the adult stage and that flight does not seem to be associated with just prereproductive or postreproductive dispersal phases, high rearing density, or short to medium periods of food deprivation. Therefore, T. castaneum level of flight activity does not seem to be associated with factors that have been shown in the literature to increase dispersal by walking for this species and to increase flight initiation in other stored-product species.

Efficacy tests were conducted using spray equipment that applies ultralow application rates of malathion NU-LURE or GF-120 spinosad by ground into citrus. Trapit Dome traps located in fields treated with malathion NU-LURE and GF-120 spinosad high rate caught significantly fewer flies than the control in all replications. Treatments reduced the Mexican fruit fly populations by 99.1 and 92.5% with malathion and 98.2 and 89.9% with GF-120 spinosad high rate. Traps in plots with lower rates of GF-120 reduced fly populations by 76.3 and 74.3% in winter and summer test, respectively. There was no indication of fly repulsion from either malathion or GF-120 spinosad during this test. The bait spray option using ground spray equipment to apply ultra-low rates of either malathion NU-LURE or GF-120 spinosad high rate is a viable cost effective treatment method to treat small acreages for A. ludens. For organic growers, the ground spray equipment is effective in applying GF-120 spinosad at the labeled rates. C1 [Conway, Hugh E.; Forrester, O.

We tested an isomer of the pheromone [(E, Z, Z)-1,3,6,9-nonadecatetraene] that previous work had suggested would inhibit captures of Bruce spanworm but not winter moths. We found that the different doses and placements of the isomer suppressed captures of both species to a similar degree. We are thus doubtful that we can use the isomer to trap winter moths without also catching Bruce spanworm. Pheromone-baited survey traps will catch both species.

Spreng., mortality in the southern United States. Effective traps and lures are needed to monitor spread of the beetle and for early detection at ports-of-entry, so we conducted a series of experiments to find the best trap design, color, lure, and trap position for detection of X. glabratus. The best trap and lure combination was then tested at seven sites varying in beetle abundance and at one site throughout the year to see how season and beetle population affected performance. Manuka oil proved to be the most effective lure tested, particularly when considering cost and availability. Traps baited with manuka oil lures releasing 5 mg/d caught as many beetles as those baited with lures releasing 200 mg/d. Distributing manuka oil lures from the top to the bottom of eight-unit funnel traps resulted in similar numbers of X. glabratus as a single lure in the middle. Trap color had little effect on captures in sticky traps or cross-vane traps. Funnel traps caught twice as many beetles as cross-vane traps and three times as many as sticky traps but mean catch per trap was not significantly different. When comparing height, traps 1.5m above the ground captured 85% of the beetles collected but a few were caught at each height up to 15 m. Funnel trap captures exhibited a strong linear relationship (r(2) = 0.79) with X. glabratus attack density and they performed well throughout the year. Catching beetles at low densities is important to port of entry monitoring programs where early detection of infestations is essential. Our trials show that multiple funnel traps baited with a single manuka oil lure were effective for capturing X. glabratus even when no infested trees were visible in the area.

TI Evaluation of Double-Decker Traps for Emerald Ash Borer (Coleoptera: Buprestidae) SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE detection tools; green leaf volatiles; manuka oil; invasive forest pest; double-decker trap ID AGRILUS-PLANIPENNIS COLEOPTERA; SEX-PHEROMONE COMPONENT; TREES; ATTRACTION; FAIRMAIRE; HOST; COL.; VOLATILES; ECOLOGY; FOLIAGE AB Improved detection tools are needed for the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), an invasive forest insect from Asia that has killed millions of ash (Fraxinus spp.) trees in North America since its discovery in Michigan in 2002. We evaluated attraction of adult A. planipennis to artificial traps incorporating visual (e.g., height, color, silhouette) and olfactory cues (e. g., host volatiles) at field sites in Michigan. We developed a double-decker trap consisting of a 3-m-tall polyvinyl pipe with two purple prisms attached near the top. In 2006, we comparedA. planipennis attraction to double-decker traps baited with various combinations of manuka oil (containing sesquiterpenes present in ash bark), a blend of four ash leaf volatiles (leaf blend), and a rough texture to simulate bark. Significantly more A. planipennis were captured per trap when traps without the rough texture were baited with the leaf blend and manuka oil lures than on traps with texture and manuka oil but no leaf blend. In 2007, we also tested single prism traps set 1.5 m above ground and tower traps, similar to double-decker traps but 6 m tall. Double-decker traps baited with the leaf blend and manuka oil, with or without the addition of ash leaf and bark extracts, captured significantly more A. planipennis than similarly baited single prism traps, tower traps, or unbaited double-decker traps. A baited double-decker trap captured A. planipennis at a field site that was not previously known to be infested, representing the first detection event using artificial traps and lures. In 2008, we compared purple or green double-decker traps, single prisms suspended 3-5 m above ground in the ash canopy (canopy traps), and large flat purple traps (billboard traps). Significantly more A. planipennis were captured in purple versus green traps, baited traps versus unbaited traps, and double-decker versus canopy traps, whereas billboard traps were intermediate. At sites with very low A. planipennis densities, more A. planipennis were captured on baited double-decker traps than on other traps and a higher percentage of the baited double-decker traps captured beetles than any other trap design. In all 3 yr, peak A. planipennis activity occurred during late June to mid-July, corresponding to 800-1,200 growing degree-days base 10 degrees C (DD(10)). Nearly all (95%) beetles were captured by the end of July at approximate to 1400 DD(10). C1 [Poland, Therese M.] USDA Forest Serv, No Res Stn, E Lansing, MI 48823 USA.

Bas TI Variable Developmental Rate and Survival of Navel Orangeworm (Lepidoptera: Pyralidae) on Pistachio SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE navel orangeworm; pistachios; development; survival; degree-days ID AMYELOIS-TRANSITELLA LEPIDOPTERA; SEX-PHEROMONE; CALIFORNIA; ALMONDS; IDENTIFICATION AB A series of laboratory and field studies were conducted using two lines of navel orangeworm, reared on different stages of new crop and mummy pistachios, Pistacia vera L. This study demonstrated the potential importance of malformed pistachios (pea splits) to the population dynamics of navel orangeworm, because these nuts, which are available as early as two months before mature nuts, supported navel orangeworm development and survival. Overall, the developmental rate on new crop pistachios is fastest on mature nuts, 422.3 +/- 123 degree-days (DD, degrees C), but other factors such as exposure to insecticide residue also sped development, although survival decreased. Development took the longest on unharvested nuts (mummies) dried at 90 degrees C for 24 h, 2,664.7 +/- 131.4 DD. In most trials development was variable and two generations could develop at the fastest rate before the slowest individual completed development, which in turn calls into question the concept of discrete generations. Generally, survival was highest on mature pistachios and other stages of new crop nut and lowest on mummies collected in May. Survival was also higher on the new varieties 'Lost Hills' and 'Golden Hills' (24.7 and 32.0%, respectively) than on the most extensively planted variety 'Kerman' (13.3%). In our trials, both the rate of development and survival were dependent on nut stage, age, variety, and quality, indicating that pistachios, like almonds, Prunus dulcis (Mill.) D.A. Webb, are a dynamic rather than a static nutrient source for navel orangeworm. C1 [Siegel, Joel P.; Kuenen, L. P. S.

The device consisted of two disks connected by string. Each disk was loaded with 1 g of SPLAT containing either 0.15% (Z,Z,E)-7,11,13-hexadecatrienal (triene) or 2% (Z,Z)-7,11-hexadecadienal (diene). The devices were deployed using a two-dimensional multivariate design to determine the optimal rate of pheromone per unit area and degree of aggregation of the deployment devices (number of trees treated per unit area). The IFM-413 device proved effective at becoming securely entangled in tree branches. Furthermore, the devices effectively delivered pheromone-loaded SPLAT that resulted in disruption of trap catch of male P. citrella. Response surfaces showed a quadratic response of trap catch disruption to both total amount of pheromone per unit area and the degree of aggregation of the deployed devices (number of treated trees per unit area). The response surfaces for 0.15% triene or 2.0% diene were similar. The diene produced an effect similar to that of the triene at approximate to 13 times the rate of the triene. The greatest disruption of trap catch occurred when the number of treated trees per unit area was greatest (no aggregation of deployment devices). Manufacturing, packaging, and mechanical deployment of the devices remain to be investigated. C1 [Lapointe, Stephen L.] ARS, USDA, US Hort Res Lab, Ft Pierce, FL 34945 USA.

TI Susceptibility of Low-Chill Blueberry Cultivars to Mediterranean Fruit Fly, Oriental Fruit Fly, and Melon Fly (Diptera: Tephritidae) SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE resistance; Vaccinium spp.; Ceratitis capitata; Bactrocera dorsalis; Bactrocera cucurbitae ID HIGHBUSH BLUEBERRIES; HAWAII; US AB No-choice tests were conducted to determine whether fruit of southern highbush blueberry, Vaccinium corymbosum L., hybrids are hosts for three invasive tephritid fruit flies in Hawaii. Fruit of various blueberry cultivars was exposed to gravid female flies of Bactrocera dorsalis Hendel (oriental fruit fly), Ceratitis capitata (Wiedemann) (Mediterranean fruit fly), or Bactrocera cucurbitae Coquillet (melon fly) in screen cages outdoors for 6 h and then held on sand in the laboratory for 2 wk for pupal development and adult emergence. Each of the 15 blueberry cultivars tested were infested by oriental fruit fly and Mediterranean fruit fly, confirming that these fruit flies will oviposit on blueberry fruit and that blueberry is a suitable host for fly development. However, there was significant cultivar variation in susceptibility to fruit fly infestation. For oriental fruit fly, 'Sapphire' fruit produced an average of 1.42 puparia per g, twice as high as that of the next most susceptible cultivar 'Emerald' (0.70 puparia per g). 'Legacy', 'Biloxi', and 'Spring High' were least susceptible to infestation, producing only 0.20-0.25 oriental fruit fly puparia per g of fruit. For Mediterranean fruit fly, 'Blue Crisp' produced 0.50 puparia per g of fruit, whereas 'Sharpblue' produced only 0.03 puparia per g of fruit. Blueberry was a marginal host for melon fly. This information will aid in development of pest management recommendations for blueberry cultivars as planting of low-chill cultivars expands to areas with subtropical and tropical fruit flies. Planting of fruit fly resistant cultivars may result in lower infestation levels and less crop loss.

No-choice infestation studies were conducted to determine whether ohelo fruit are hosts for four invasive tephritid fruit fly species. Ohelo berries were exposed to gravid female flies of Bactrocera dorsalis Hendel (oriental fruit fly), Ceratitis capitata (Wiedemann) (Mediterranean fruit fly), Bactrocera cucurbitae Coquillet (melon fly), or Bactrocera latifrons (Hendel) in screen cages outdoors for 24 h and then held on sand in the laboratory for 2 wk for pupal development and adult emergence. Only B. dorsalis successfully attacked and developed in ohelo berries. In total, 1,570 berries produced 10 puparia, all of which emerged as adults, for a fruit infestation rate of 0.0064% and an average of 0.0053 puparia per gram of fruit. By comparison, papaya fruit used as controls produced an average of 1.44 B. dorsalis puparia per g of fruit. Ohelo berry is a marginal host for B. dorsalis and apparently a nonhost for C. capitata, B. cucurbitae, and B. latifrons. Commercial plantings of ohelo will rarely be attacked by fruit flies in Hawaii. C1 [Follett, Peter A.; Zee, Francis T.] ARS, USDA, US Pacific Basin Agr Res Ctr, Hilo, HI 96720 USA.

TI Species Dependent Influence of (-)-alpha-Pinene on Attraction of Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae) to Ethanol-Baited Traps in Nursery Agroecosystems SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE ethanol; alpha-pinene; ambrosia beetles; Scolytinae ID TRYPODENDRON-LINEATUM COLEOPTERA; ALPHA-PINENE; BARK BEETLES; STRESS; KAIROMONES; VOLATILES; FLIGHT AB Field-based trapping experiments were conducted in Ohio in 2003, 2004, and 2008 to determine the influence of (-)-alpha-pinene on the attraction of exotic and native ambrosia beetles (Coleoptera: Curculionidae: Scolytinae) to ethanol-baited traps. In 2003 and 2004, we determined the effect of adding an (-)-alpha-pinene ultrahigh release lure (UHR; 2 g/d at 20 degrees C) to traps baited with an ethanol UHR lure (0.39 g/d). Fewer Anisandrus (Xyleborus) sayi (Hopkins) and Xyleborinus saxeseni (Ratzeburg) were collected in 2003 and 2004 from traps baited with ethanol UHR plus (-)-alpha-pinene UHR compared with ethanol UHR. (-)-alpha-Pinene also reduced the attraction of Xyloterinus politus (Say) to ethanol-baited traps in 2004. Total captures of Xylosandrus germanus (Blandford) in 2003 were higher in traps baited with ethanol UHR plus (-)-alpha-pinene UHR than in traps with ethanol UHR alone but not in 2004. In 2008, captures were compared among traps baited with eight combinations of ethanol and (-)-alpha-pinene at both UHR and low release (LR) rates. Release rates for ethanol LR and (-)-alpha-pinene LR were 0.027 and 0.0015 g/d, respectively. (-)-alpha-Pinene UHR and (-)-alpha-pinene LR reduced the attractiveness of ethanol UHR to A. sayi and X. saxeseni. Ethanol UHR was also more attractive than ethanol LR to A. sayi and X. germanus. These findings demonstrate traps baited with ethanol alone are more effective than ethanol plus (-)-alpha-pinene for monitoring ambrosia beetle flight activity in ornamental nurseries. Ethanol release rate is also an important consideration for monitoring purposes. C1 [Ranger, Christopher M.; Reding, Michael E.] ARS, Hort Insects Res Lab, USDA, Wooster, OH 44691 USA.

TI Effects of Insecticides on Behavior of Adult Bactericera cockerelli (Hemiptera: Triozidae) and Transmission of Candidatus Liberibacter psyllaurous SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE potato psyllid; potato; insecticides; IPM; "zebra chip" ID MYZUS-PERSICAE; PSYLLID YELLOWS; DIAPHORINA-CITRI; POTATO; HOMOPTERA; TOMATO; SULC; ANTIFEEDANT; LEAFHOPPER; RESPONSES AB The potato psyllid, Bactericera cockerelli (Sulc) (Hemiptera: Triozidae), is a serious pest of potatoes (Solanum tuberosum L.) that can cause yield loss by direct feeding on crop plants and by vectoring a bacterial pathogen, Candidatus Liberibacer psyllaurous. Current pest management practices rely on the use of insecticides to control the potato psyllid to lower disease incidences and increase yields. Although many studies have focused on the mortality that insecticides can cause on potato psyllid populations, little is known regarding the behavioral responses of the potato psyllid to insecticides or whether insecticides can decrease pathogen transmission. Thus, the objectives of this study were to determine the effects of insecticides on adult potato psyllid behaviors, the residual effects of insecticides on potato psyllid behaviors over time, and effects of these insecticides on Ca. L. psyllaurous transmission. Insecticides tested included imidacloprid, kaolin particle film, horticultural spray oil, abamectin, and pymetrozine. All insecticides significantly reduced probing durations and increased the amount of time adult psyllids spent off the leaflets, suggesting that these chemicals may be deterrents to feeding as well as repellents. Nonfeeding behaviors such as tasting, resting, and cleaning showed variable relationships with the different insecticide treatments over time. The insecticides imidacloprid and abamectin significantly lowered transmission of Ca. L. psyllaurous compared with untreated controls. The implications of our results for the selection of insecticides useful for an integrated pest management program for potato psyllid control are discussed.

TI Among-Sampler Variation in Sweep Net Samples of Adult Lygus hesperus (Hemiptera: Miridae) in Cotton SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE sampling; cotton; sweep net; plant bug ID TARNISHED PLANT BUGS; HETEROPTERA; ABSOLUTE AB The sweep net is a standard sampling method for adults of the western tarnished plant bug, Lygus hesperus Knight (Hemiptera: Miridae), in cotton (Gossypium spp.). However, factors that influence the relationship between true population levels and population estimates obtained using the sweep net are poorly documented. Improved understanding of these factors is needed for the development and application of refined treatment thresholds. Recent reports of significant among-sampler differences in sweep net-based population estimates of the adult tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), seem to preclude meaningful comparisons of population estimates collected by different samplers. We used a mark-release-recapture method and the standard sweep net to evaluate among-sampler differences in population estimates of L. hesperus adults. Adult lygus, marked with fingernail polish to facilitate identification and prevent flight, were released into 10-m sample rows on the evening before 10-sweep samples were collected the following morning. The experimental design was a randomized complete block with three replications of three treatments (sampler). Separate experiments were conducted in two plantings each of Pima (Gossypium barbadense L.) and Acala (Gossypium hirsutum L.) cotton. Collections of marked bugs from each study were evaluated for effects of sampler, sample date, and their interaction. Although differences in lygus collections were observed among sample dates in some tests, no differences were detected in the population estimates by different samplers. These results demonstrate that the sweep net technique can be sufficiently standardized to allow direct comparison of population estimates obtained by different samplers. C1 [Spurgeon, D.

Simulations were run for each of 10 yr with 1 August as the start date; 31 December as the end date; beginning populations of 2.5 adults per metric ton (1,000 kg); starting grain temperatures of 29.4, 32.2, and 35.0 degrees C; and aeration airflow rates of 0.27, 0.79, and 1.40 m(3)/min/metric ton of rice. In the absence of aeration, populations of both species increased exponentially, with maximum production of R. dominica and S. oryzae at starting grain temperatures of 35.0 and 32.2 degrees C, respectively. Final predicted populations of R. dominica on 31 December from grain starting temperatures of 29.4, 32.2, and 35.0 degrees C were 5,465, 6,848, and 11,855 per ton, respectively; final predicted populations of S. oryzae were 13,288, 21,252 and 4,355, respectively. Aeration led to a reduction in grain temperature and a decrease in pest populations, regardless of starting grain temperature or aeration airflow rates. Predicted populations of R. dominica on 31 December ranged from 12 to 63 adults per ton at all grain starting temperatures and airflow rates; populations of S. oryzae on 31 December ranged from 108 to 193 adults per ton at all grain starting temperatures and airflow rates. The predicted population levels in aerated rice represented at least a 98% reduction compared with unaerated rice. Results show the utility of the web-based model and how the various model inputs can help define broader patterns of insect control in rice stored in the south central United States. C1 [Arthur, F.

The assay uses unmodified chitin oligosaccharide substrates and is readily achievable on a microliter scale (2 mu l of total volume containing 2 mu g of substrate and 1 ng of protein). The speed and sensitivity of the assay make it potentially well suited for the high-throughput screening of chitinase inhibitors. The mass spectrum is acquired in approximately 2 min, as opposed to typically 30-40 min for a single run with a high-performance liquid chromatography (HPLC)-based assay. By using the multiple-place MALDI MS targets, we estimate that 100 assays could be run in approximately 2-3 h without needing to remove the target from the instrument. In addition, because the substrate and product chitomers are visualized simultaneously in the TOF spectrum, this gives immediate information about the cleavage site and mechanism of the enzyme under study. The assay was used to monitor the purification and transgenic expression of plant class IV chitinases. By performing the assay with chitomer substrates and C-glycoside chitomer analogs, the enzyme mechanism of the class IV chitinases is described for the first time. Published by Elsevier Inc.

Farinetta flour contained the highest free and bound phenolic contents, followed by Supreme, whole buckwheat, and Fancy flour, respectively. The 50% ethanol extraction achieved significantly higher free phenolic content compared with water and absolute alcohol. The absolute ethanol extraction contained considerable more bound phenolic and flavonoid compounds. A high extraction temperature increased the phenolic contents. The optimal solvent to solids ratio was 50:1, and the optimal extraction time was 5 h for flavonoids. The spectral method was reproducible for analysing the total flavonoid contents. The LC-ESI-Q-TOF-MS studies on whole buckwheat flour showed that p-coumaric and gallic acids were found in the bound phenolics along with isoquercitrin but were not present in the free phenolic compounds. The free flavonol-glycosides were found in whole buckwheat flour but not in any other buckwheat flours. Published by Elsevier Ltd.

In the northwestern U.S., these changes will likely decrease snowpack, cause earlier snowmelt, increase summer evapotranspiration, and increase the frequency and severity of droughts. Elevated [CO2] and warmer temperatures may have positive effects on growth and productivity where there is adequate moisture or growth is currently limited by cold. However, the effects of climate change are generally expected to reduce growth and survival, predispose forests to disturbance by wildfire, insects, and disease; and ultimately change forest structure and composition at the landscape scale. Substantial warming will likely decrease winter chilling resulting in delayed bud burst, and adversely affect flowering and seed germination for some species. The extent of these effects will depend on the magnitude of climate change, the abilities of individual trees to acclimate, and for tree populations to adapt in situ, or to migrate to suitable habitats. These coping mechanisms may be insufficient to maintain optimal fitness of tree populations to rapidly changing climate. Physiological responses to climatic stresses are relatively well-understood at the organ or whole-plant scale but not at the stand or landscape scale. In particular, the interactive effects of multiple stressors is not well known. Genetic and silvicultural approaches to increase adaptive capacities and to decrease climate-related vulnerabilities of forests can be based on ecophysiological knowledge. Effective approaches to climate adaptation will likely include assisted migration of species and populations, and density management. Use of these approaches to increase forest resistance and resilience at the landscape scale requires a better understanding of species adaptations, within-species genetic variation, and the mitigating effects of silvicultural treatments.

At the Humboldt site trees that had experienced three to four defoliation events had more negative water potentials and lower foliar Delta(13)C than trees farther from the release site that had experienced only one defoliation event. We established paired trees (exposed to D. carinulata and sprayed with insecticide) at both sites and monitored impacts. Beetles reduced stem growth during the first year of defoliation at both sites but not in the second year at the Humboldt site. Defoliation did not affect midday water potentials, or leaf gas exchange during the first two years of defoliation of paired trees at either site. Furthermore there was no difference in foliar Delta(13)C in either year at the Humboldt site but defoliation during the first year lead to higher foliar Delta(13)C at the Walker site. These results suggest that initial defoliation by D. carinulata reduces growth but not water relations of saltcedar. However, repeated defoliation, potentially acting through reduced root growth, leads to an overall reduction in the water status of this invader. Published by Elsevier Ltd. C1 [Pattison, R.

Organic carbon lost to streams and rivers can promote bacterial production and microbial respiration of CO(2) to the atmosphere. Although pastures and grasslands are major land uses in the humid U.S., row crop agriculture has received most of the carbon research focus. The objective of this study at the North Appalachian Experimental Watershed near Coshocton, Ohio, was to assess organic carbon transported from a pasture system, particularly on a runoff event basis. A beef cow-calf herd rotationally grazed a paddock during the growing season and was fed hay in this paddock during the dormant season (November-April). Surface runoff and sediment loss was measured and sampled throughout the year from the small watershed in the paddock. Most of the sediment samples were collected during the dormant season. With continuous winter occupancy, the percent vegetative cover was often <= 50% in the late winter/early spring, which increased the potential for soil loss. During the 10-year period of sample collection, there were 376 runoff events and 115 events with sediment loss >= 10 kg ha(-1) from the watershed in the winter feeding area. The largest 6 events carried nearly 50% of the total sediment and sediment-attached C lost during this period. Annual losses of sediment and sediment-C varied considerably but averaged 2642 and 140 kg ha(-1), respectively. There was no significant correlation between the amount of sediment transported during individual events and the C concentration on the associated sediment. The pasture sediments have a C enrichment ratio of 1.2-1.5 compared with the 0-2.5 cm soil layer. Pasture sediment-C concentrations were >2x the C concentrations on sediments from nearby row crop watersheds. Published by Elsevier B.V.

Studying the patterning of genetic variation among pine populations along altitudinal gradients under simulated climatic change temperatures, would provide insights about how to realign the present populations to future environments. Fourteen Pinus patula populations from the forests of the Native Indian Community of Ixtlan de Juarez, state of Oaxaca, Mexico, were collected in January-March 2005 and 2006 along an altitudinal gradient (2400 m to 3050 m, one population every 50 m of altitudinal difference). Seedlings were grown in growth chambers at the Laurentides Forestry Center, Quebec city, Canada, under two temperature treatments aiming to simulate: contemporary temperature (average 17 degrees C) and a future global warming scenario (average 21 degrees C). Seedlings were evaluated after inducing a second growing season (between 8 and 12 months of age). Populations differed significantly (p <= 0.001) for seedling height and aerial dry weight, and exhibited a significant (p <= 0.02) although weak altitudinal clinal pattern, with populations from lower altitudes having on average taller and heavier seedlings than populations from higher altitudes (r(2)=0.064 and r(2)=0.094).

TI Detection of bacterial aggregation in tobacco cell suspensions treated with pathogenic bacteria SO PHYSIOLOGICAL AND MOLECULAR PLANT PATHOLOGY LA English DT Article DE Bacterial; Cell suspension; Aggregation; Agglutination ID CULTURED SYCAMORE CELLS; ERWINIA-CHRYSANTHEMI; ATTACHMENT; INDUCTION; VIRULENCE; RESPONSES; POLYSACCHARIDE; RECOGNITION; INVOLVEMENT; ACTIVATION AB Previous studies of this model system involving plant cell suspensions inoculated with bacteria, have documented that interactions with incompatible pathogens, which cause a hypersensitive response on whole plants, will cause a transient increase in oxygen uptake 2-4 h after inoculation. The initial objective of this study was to determine whether this oxygen uptake burst was a result of increased bacterial multiplication, possibly due to nutrient leakage from plant cells. The adaptation of flow cytometry and the use of fluorescent nucleic acid stains provided the precision needed to monitor bacterial concentrations in tobacco suspension cells inoculated with pathogenic and non-pathogenic Pseudomonas species. Surprisingly, there was a transient decrease in the planktonic, or free-living, bacteria in cell suspensions inoculated with isolate Pseudomonas syringae pv. syringae WT (HR+), an incompatible pathogen of tobacco. This decrease in planktonic numbers was followed by an apparent increase in bacterial multiplication. Examination of the samples with fluorescent microscopy revealed the formation of bacterial aggregates in the extracellular fluid of the Pss WT (HR+) inoculated plant cells. The size of the aggregates increased at the onset of the oxygen uptake response, and contained increasing numbers of bacterial cells. These aggregated bacterial cells appear to be removed along with plant cells, as a result of filtration during sample preparation, causing the apparent decrease in planktonic bacteria detected by flow cytometry. This bacterial aggregation was also observed with the compatible Pseudomonas tabaci pathogen, which does not induce a noticeable oxygen uptake burst. No aggregation was observed with suspension inoculated with Pseudomonas fluorescens, a saprophyte, or Pss B7 (HR-), a Tn5 mutant of P. s. syringae. This aggregation response was rapid, once initiated, and appeared similar to reports of adhesion involving Hrp pili. Published by Elsevier Ltd. C1 [Baker, C.

Koske could enhance the post-transplant growth of two cultivars of Leucaena leucocephala (Lam.) de Wit (cv. K-8 and cv. K-636) in Al- and Mn-rich acid soils was evaluated in a greenhouse. Arbuscular mycorrhizal colonization measured at the end of the experiment was significantly stimulated by inoculation in both cultivars at all pH levels tested, although colonization was most stimulated if cv. K-8 was grown in the Al-rich soil at the lowest pH. Symbiotic effectiveness measured as P content of Leucaena pinnules was significantly suppressed in both cultivars if they were grown at the lowest pH. Symbiotic effectiveness measured as pinnule P content and shoot biomass yield was enhanced in both cultivars by liming. The trends in effectiveness were similar in both cultivars, but cultivar effect was significant in the Mn-rich Oxisol (Wahaiawa soil) but not in the Al-rich Ultisol (Leilehua soil). The tolerance of the cultivars to acid soil toxicity in the Wahiawa soil varied with the pretransplant mycorrhizal status of their seedlings. The effect of pretransplant colonization of seedlings was to eliminate the differences in the tolerance of the cultivars to acid soil toxicity. Our data suggest that AMP could offset some of the growth reduction associated with soil acidity and that host genotype could play a role in this regard.

Replicated experiments were established in five regions. At each site, two complete installations differed in time since disturbance: "new" units were harvested immediately before spring planting and "old" units were harvested at least 3 years before planting. We compared mechanical scarification before planting, broadcast herbicide application during the fall before planting, and no site preparation with 1-year-old container-grown seedlings from two sources, 2-year-old bare-root transplants from two sources, and 3-year-old bare-root transplants. Seedlings were followed for 11 years on most sites. Based on meta-analyses, seedling survival increased 10% with herbicide application and 15% with mechanical scarification compared with no site preparation. Scarification and herbicide application increased seedling height by about 28% and 35%, respectively, and increased seedling volume by about 86% and 195%, respectively, compared with no site preparation. Soil temperature did not differ among site preparation methods after the first 7 years. Results suggest that white spruce stands may be successfully restored through a combination of vegetation control and use of quality planting stock.

TI Assessing landowner preferences for forest management practices to prevent the southern pine beetle: An attribute-based choice experiment approach SO FOREST POLICY AND ECONOMICS LA English DT Article DE Choice experiment; Forest management; Financial incentive; Southern pine beetle; Cost-share program; Landowner survey ID BIODIVERSITY; VALUATION; FLORIDA; MODEL AB Southern pine beetle (SPB) prevention cost-share programs provide a financial incentive to private forest landowners in exchange for undertaking forest management practices that improve stand health. Healthy pine trees in low density stands offer the best defense against the SPB, helping to ensure that timber resources and other benefits of forests are protected against infestations. This study evaluates the preferences of forestland owners for selected forest management treatment practices (e.g., thinning) offered under this program. An attribute-based choice experiment approach was used to achieve the task. Results indicate that replanting is the option most favored by forestland owners, while prescribed burning is observed to produce disutility. Thinning was statistically insignificant, as were spatial interaction terms and a variable representing the relative rate of landowner participation in the choice scenario. (C) 2011 Elsevier B.V.

Gerdemann and Trappe. Best results were achieved with a long-term bioassay (7-8 d) with nanomolar concentrations throughout the Petri dish in contrast to the rapid microinjection bioassay (16-24 h) in which nanogram quantities were injected near growing hyphal tips. When 5 nM 2-hydroxy fatty acids of various chain length were tested, the length of the hydroxyl fatty acid was significant since only 2-hydroxytetradecanoic acid (2OH-TDA) and to a slightly lesser degree, 2-hydroxydodecanoic acid (2OH-DDA) induced a hyphal growth response while 2-hydroxydecanoic acid (2OH-DA) and 2-hydroxyhexadecanoic (2OH-HDA) acid did not. The position of the hydroxyl group was critical since 5 nM 3-hydroxytetradecanoic acid (3OH-TDA) had no effect on hyphal growth. The length of the non-hydroxy containing straight chain fatty acid, per se, did not appear significant since none of these fatty acids had an effect on hyphal growth. The morphological growth response promoted by 2OH-TDA consisted of multiple lateral branches, spaced fairly regularly apart, along the primary germ tubes as well as some lateral branch formation off the major secondary hyphae. This growth response was identical to that observed when germinated spores were allowed to grow towards cultured carrot roots in vitro. This response to 2OH-TDA also was observed with an unidentified Gigaspora species but no morphological response was observed with Glomus intraradices Schenck and Smith. The results indicate that 2-hydroxy fatty acids are another putative category of root exudate signals perceived by Gigaspora species, stimulating an increase in elongated lateral branches.

NICOTIANAE; TOBACCO BLACK SHANK; SUDDEN OAK DEATH; SEQUENCE DATA; NUCLEAR; INFESTANS; RAMORUM; MARKERS; POPULATIONS; DIVERSITY AB A new method based on the analysis of mitochondrial intergenic regions characterized by intraspecific variation in DNA sequences was developed and applied to the study of the plant pathogen Phytophthora nicotianae. Two regions flanked by genes trnY and ms and trnW and cox2 were identified by comparing the whole mitochondrial genomes of Phytophthora infestans, Phytophthora ramorum, and Phytophthora sojae and amplified using primers designed from the flanking conserved genes. These regions were sequenced from 51 isolates of P. nicotianae of both A1 and A2 mating type recovered from different hosts and geographic regions. Amplicon length varied from 429 bp to 443 bp (trnY/rns) and 322 bp to 373 bp (trnW/cox2) with intraspecific variation due to single nucleotide polymorphisms and indels. Seventeen, seven and 20 different haplotypes were detected by individually analyzing regions trnY-rns, trnW-cox2 and the combined data set of sequences from both regions, respectively. Phylogenetic analysis inferred with three different methods enabled the grouping of isolates in five clades, each containing different mitochondrial haplotypes and revealed diversity in the mitochondrial genome of P. nicotianae. The majority of isolates from citrus grouped in a single clade indicating either movement of isolates on planting stock or an association of particular isolates with this host. Phylogenetic groups were not correlated with the radial growth rate of the isolates or the rapidity of apple flesh colonization. The method developed in the present study represents an innovative molecular tool for the characterization of natural populations of P. nicotianae and should be easily expanded to other species of Phytophthora as well as other plant pathogens. It can be used to track specific haplotypes and, thanks to its high genetic resolution, it could be standardized and applied in a DNA barcoding like strategy for the precise identification of sub-specific taxa. Compared to alternative molecular methods, a major advantage is that results are unbiased (a list of nucleotides) and highly reproducible, thus enabling the comparison of data from different laboratories and time periods. Furthermore, the method could be further enhanced by the identification of additional variable mitochondrial and/or nuclear genomic regions. (C) 2011 The British Mycological Society.

Cache-site selection has not been formally studied in Clark's Nutcrackers, which are considered effective seed dispersers for pines because past studies have found that they harvest and store large quantities of seeds. Although many seeds are placed in sites suitable for germination and establishment, information is lacking on the proportions of seeds placed in suitable versus unsuitable sites. We used radiotelemetry to investigate cache-site selection and evaluate the suitability of selected cache sites for establishment of Whitebark and Ponderosa (P. ponderosa) pines. On a landscape scale, Clark's Nutcrackers cached seeds centrally within home ranges, even though this required them to transport seeds up to 32.6 km. They selected low-elevation forests for caching, presumably because these sites accumulated little snow. When caching at high elevations, the birds placed most seeds in aboveground microsites. Only 15% of Whitebark Pine seed caches (n = 155 caches) were placed below ground and in habitats where seeds could germinate and seedlings grow. For comparative purposes, 42% of Ponderosa Pine seed caches were placed in suitable habitats and below ground. Although Whitebark Pine is an obligate mutualist of Clark's Nutcracker, our study suggests that Clark's Nutcrackers in some populations may be more effective seed dispersers for Ponderosa Pine than for Whitebark Pine.

TI SEROPREVALENCE OF TOXOPLASMA GONDII AND CONCURRENT BARTONELLA SPP., FELINE IMMUNODEFICIENCY VIRUS, FELINE LEUKEMIA VIRUS, AND DIROFILARIA IMMITIS INFECTIONS IN EGYPTIAN CATS SO JOURNAL OF PARASITOLOGY LA English DT Article ID EPIDEMIOLOGIC OBSERVATIONS; DOMESTIC CATS; STRAY CATS; PREVALENCE; HENSELAE; GUIDELINES; ANTIBODIES; MANAGEMENT; BALTIMORE; BLOOD AB Toxoplasma gondii and Bartonella spp. are zoonotic pathogens of cats. Feline immunodeficiency virus (FIV) and feline leukemia virus (FeLv) are related to human immunodeficiency virus and human leukemia virus, respectively, and these viruses are immunosuppressive. In the present study, the prevalence of antibodies to T. gondii, Bartonella spp., FIV, as well as FeLv and Dirofilaria immitis antigens was determined in sera from feral cats (Felis catus) from Cairo, Egypt. Using a modified agglutination test, antibodies to T. gondii were found in 172 (95.5%) of the 180 cats with titers of 1:5 in 9, 1:10 in 9, 1:20 in 3, 1:40 in 5, 1:80 in 5, 1:160 in 15, 1:320 in 22, and 1:640 or higher in 104. Thus, 57.4% had high T. gondii titers. Antibodies to Bartonella spp. were found in 105 (59.6%) of 178, with titers of 1:64 in 45, 1:128 in 39, 1:256 in 13, 1:512 in 3, 1:1,024 in 4, and 1:2,048 in 1 cat. Antibodies to FIV were detected in 59 (33.9%) of 174 cats. Of 174 cats tested, antigens to FeLv, and D. immitis were detected in 8 (4.6%) and 6 (3.4%) cats, respectively. The results indicate a high prevalence of T. gondii, Bartonella spp., and FIV infections in cats from Cairo, Egypt. This is the first report of Bartonella spp., and D. immitis infection in cats in Egypt. C1 [Al-Kappany, Y. M.; Lappin, M. R.; Kwok, O. C. H.; Abu-Elwafa, S. A.; Hilali, M.; Dubey, J.

Existing serological assays can determine previous exposure to the parasite, but not the route of infection. We have used difference gel electrophoresis, in combination with tandem mass spectroscopy and Western blot, to identify a sporozoite-specific protein (T. gondii embryogenesis-related protein [TgERP]), which elicited antibody and differentiated oocyst-versus tissue cyst-induced infection in pigs and mice. The recombinant protein was selected from a cDNA library constructed from T. gondii sporozoites; this protein was used in Western blots and probed with sera from T. gondii-infected humans. Serum antibody to TgERP was detected in humans within 6-8 mo of initial oocyst-acquired infection. Of 163 individuals in the acute stage of infection (anti-T. gondii IgM detected in sera, or <30 in the IgG avidity test), 103 (63.2%) had detectable antibodies that reacted with TgERP. Of 176 individuals with unknown infection route and in the chronic stage of infection (no anti-T. gondii IgM detected in sera, or >30 in the IgG avidity test), antibody to TgERP was detected in 31 (17.6%). None of the 132 uninfected individuals tested had detectable antibody to TgERP. These data suggest that TgERP may be useful in detecting exposure to sporozoites in early T. gondii infection and implicates oocysts as the agent of infection.

TI UP Hedrick Award Winner 2010: Primocane-fruiting in Black Raspberry (Rubus occidentalis L.) SO JOURNAL OF THE AMERICAN POMOLOGICAL SOCIETY LA English DT Article ID BLACKBERRIES; INHERITANCE AB Production of fruit on first year canes, or primocane-fruiting in caneberries (Rubus L.) has proven to be an important trait, allowing production, particularly for the fresh market, to expand into new geographic areas and non-traditional seasons. While not a new trait, primocane-fruiting black raspberries have received new attention from breeders in recent years. Despite this, relatively little is known about primocane-fruiting in black raspberry because historical sources of the trait have been lost, and little has been written on the subject. Modem sources of primocane-fruiting include seedlings of floricane-fruiting black raspberry cultivars as well as wild black raspberry germplasm. Expression of primocane fruiting in these plants is variable, and further study on the genetic control of primocane fruiting and the effects of environmental influences on expression are needed.

TI Estimating Occupancy to Monitor Northern Goshawk in the Central Rocky Mountains SO JOURNAL OF WILDLIFE MANAGEMENT LA English DT Article DE Accipiter gentilis; aspen; lodgepole pine; management indicator species; northern goshawk; ponderosa pine; regional occupancy monitoring; spruce-fir; stratified design; trend monitoring ID TRACK SURVEYS; POPULATIONS; POWER AB Designing monitoring programs to evaluate trends in low-density wildlife species at regional scales is challenging given difficulties detecting uncommon organisms distributed in potential habitats over large spatial extents. The northern goshawk (Accipiter gentilis) has been petitioned for listing under the Endangered Species Act and the review of the petition indicated a need for information on population trend. To evaluate trends in goshawk populations, the U. S. Forest Service developed the Northern Goshawk Bioregional Monitoring Design to estimate goshawk occupancy over broad spatial extents. We adapted and implemented this design to approximately 30,600 km(2) of 88,128 km(2) of National Forest System lands in the Forest Service Rocky Mountain Region, including portions of Colorado, Wyoming, and South Dakota. We developed a stratified random design to monitor goshawk occupancy in sampling units, defined by primary and secondary habitat quality as well as accessibility. To define habitat quality, we examined a time series for 58 previously located nesting territories. Using logistic regression, we found that the dominant conifer species and status of aspen in postfledging zones best characterized high-quality goshawk nesting habitat. We applied model results to stratify 4,445 sampling units based on habitat quality and further stratified sampling units based on accessibility into easy and difficult access categories. We conducted field sampling during the goshawk breeding season in the summer of 2006 to estimate detection probabilities and occupancy rates. Within our sampling frame, we sampled 51 sampling units and estimated goshawk occupancy ((P) over cap) of 0.329 (95% CI: 0.213-0.445). Occupancy within primary strata (high quality) sampling units was 0.811 (SE = 0.113), whereas occupancy in secondary strata (lower quality) sampling units was 0.124 (SE = 0.067). Future implementation of this monitoring program can achieve 0.8 power to detect 30-40% declines in (P) over cap with 140 sampling units. Our implementation of a stratified sampling design to monitor occupancy of goshawks at a region-wide scale reduced the number of sampling units in each administrative unit and focused our efforts on those areas most likely to have goshawks.

TI Barred Owl Occupancy Surveys Within the Range of the Northern Spotted Owl SO JOURNAL OF WILDLIFE MANAGEMENT LA English DT Article DE barred owl; detection probability; northern spotted owl; occupancy modeling; Oregon; Strix occidentalis caurina; Strix varia ID HABITAT SELECTION; STRIX-VARIA; OWNERSHIP; OREGON; VOCALIZATIONS; OCCIDENTALIS; RATES AB The range expansion by barred owls (Strix varia) into western North America has raised considerable concern regarding their potential effects on declining northern spotted owl (Strix occidentalis caurina) populations, yet most information on the occurrence of barred owls in the region is limited to incidental detections during surveys for spotted owls. To address this shortcoming we investigated response behavior, detection probabilities, and landscape occupancy patterns of barred owls in western Oregon, USA, during conspecific versus spotted owl call-broadcast surveys. Subtle differences in barred owl response behavior to conspecific versus spotted owl vocalizations combined with minor procedural differences between species-specific survey protocols led to a sizeable difference in estimated detection probabilities during conspecific (0.66, 95% CI = 0.61-0.71) versus spotted owl (0.48, 95% CI = 0.39-0.56) surveys. We identified 61 territorial pairs of barred owls during repeated surveys of a multi-ownership study area with the probability of occupancy being highest in the structurally diverse mixture of mature and old forests that occurred almost entirely on public lands. Our findings suggest that research and management strategies to address potential competitive interactions between spotted owls and barred owls will require carefully designed, species-specific survey methods that account for erratic response behaviors and imperfect detection of both species. Our sampling methods can be used by forest managers to determine the occurrence and distribution of barred owls with high confidence. (C) 2011 The Wildlife Society. C1 [Wiens, J.

We compared estimates of detection probability and density from distance and time-removal models and survey protocols based on 5- or 10-min counts and outer radii of 50 or 100 m. We surveyed singing male Acadian flycatchers (Empidonax virescens), cerulean warblers (Dendroica cerulea), Kentucky warblers (Oporornis formosus), Louisiana waterthrushes (Parkesia motacilla), wood thrushes (Hylocichla mustelina), and worm-eating warblers (Helmitheros vermivorum) in bottomland and upland forest across 5 states in the Central Hardwoods Bird Conservation Region during the breeding season in 2007 and 2008. Detection probabilities differed between distance and time-removal models and species detectabilities were affected differently by year, forest type, and state. Density estimates from distance models were generally higher than from time-removal models, resulting from lower detection probabilities estimated by distance models. We found support for individual heterogeneity (modeled as a finite mixture model) in the time-removal models and that 50-m radius counts generated density estimates approximately twice as high as 100-m radius counts. Users should be aware that in addition to estimating different components of detectability, density estimates derived from distance and time-removal models can be affected by survey protocol because some count durations and plot radii may better meet model assumptions than others. The choice of a method may not affect the use of estimates for relative comparisons (e. g., when comparing habitats) but could affect conclusions when used to estimate population size. We recommend careful consideration of assumptions when deciding on point-count protocol and selection of analysis methods. (C) 2011 The Wildlife Society. C1 [Reidy, Jennifer L.; Bailey, J.

We determined if accounting for trap density provided a better explanation of observed capture rates. Based on a sample of 24 captured coyotes (6 inside core areas and 18 on peripheries of occupied areas) the best fitting model describing capture location only accounted for trap density and not relative time spent in each region. Our results suggest that coyote capture rates are a function of trap density in an area and not novelty avoidance. Placing traps in core areas of territories can increase the probability of capturing individuals from specific territories to increase the effectiveness of management or research activities.

TI A Reappraisal of the Evidence for Regulation of Wolf Populations SO JOURNAL OF WILDLIFE MANAGEMENT LA English DT Article DE numerical response; prey limitation regulation; Type 1; Type 2; Type 3; wolves ID FUNCTIONAL-RESPONSES; MOUNTAIN LIONS; WOLVES; SIZE AB The dogma that gray wolf (Canis lupus) population densities in naturally occurring systems are limited almost solely by available ungulate biomass is based upon studies that fit straight line linear regressions (Type 1 numerical response) to data collected at 32 sites across North America. We fit Type 1, 2, and 3 response functions to the data using linear and nonlinear regression as appropriate and found that the evidence supported wolf population regulation by density-dependence as much as limitation by prey availability. When we excluded 4 of 32 points from the original data set because those points represented exploited or expanding wolf populations the data suggested that wolf populations are self regulated rather than limited by prey biomass by at least a 3:1 margin. In establishing goals for sustainable wolf population levels, managers of wolf reintroductions and species recovery efforts should account for the possibility that some regulatory mechanism plays an important role in wolf population dynamics.

Our objectives were to 1) test the system on a wild population of wolverines using an array of camera and hair-snag (C&H) stations in forested habitat where wolverines were known to occur, 2) validate our ability to determine identity (ID) and sex from photographs by comparing photographic data with that from DNA, and 3) encourage researchers and managers to test the system in different wolverine populations and habitats and improve the system design. Of the 18 individuals (10 M, 8 F) for which we obtained genotypes over the 2 years of our study, there was a 100% match between photographs and DNA for both ID and sex. The integrated system made it possible to reduce cost of DNA analysis by >74%. Integrating motion-detection cameras and hair snags provides a cost-effective technique for wildlife managers to monitor wolverine populations in remote habitats and obtain information on important population parameters such as density, survival, productivity, and effective population size.

Their defense to herbivory may differ from their native counterparts, potentially influencing the effectiveness of biological control. If invasive plants have decreased resistance but increased tolerance to enemies, insect herbivores may rapidly build up their populations but exert weak control. Moreover, resource availability to plants may affect the efficacy of biological control agents. We tested these predictions using Chinese tallow tree (Triadica sebifera) and two specialist herbivores (Heterapoderopsis bicallosicollis and Gadirtha inexacta) that are candidates for biological control. We performed a pair of field common garden experiments in China in which Triadica seedlings from the native or introduced range were grown in low or high light conditions and subjected to different levels of herbivory by each herbivore in a factorial design. We found that Heterapoderopsis achieved greater densities on tallow trees from the introduced range or when trees were grown in high light conditions. When Gadirtha was raised in the lab on tallow tree foliage we found that it performed better (larger pupal size) when fed foliage from introduced populations. However, introduced populations generally had greater herbivore tolerance such that the impact of each agent on plant performance was lower than on native populations despite higher herbivore loads. Tallow trees grew more slowly and achieved smaller sizes in lower light levels, but the impact of biological control agents was comparable to that found for higher light levels. Plants from introduced populations grew larger than those from native populations in all conditions. Our results suggest that reduced resistance and increased tolerance to herbivory in introduced populations may impede success of biological control programs. Biological control practitioners should include plants from the introduced range in the prerelease evaluation, which will help predict insect impact on target weeds.

TI Scale-dependent controls on the area burned in the boreal forest of Canada, 1980-2005 SO ECOLOGICAL APPLICATIONS LA English DT Article DE area burned; boosted regression trees; Canadian boreal forest; climate; ignitions; regression modeling; spatial scale; topography; vegetation; wildfire ID LIGHTNING FIRE INITIATION; CLIMATE-CHANGE; SPATIAL-PATTERNS; WILDFIRE; WEATHER; MODELS; IMPACTS; FREQUENCY; MIXEDWOOD; REGIMES AB In the boreal forest of North America, as in any fire-prone biome, three environmental factors must coincide for a wildfire to occur: an ignition source, flammable vegetation, and weather that is conducive to fire. Despite recent advances, the relative importance of these factors remains the subject of some debate. The aim of this study was to develop models that identify the environmental controls on spatial patterns in area burned for the period 1980-2005 at several spatial scales in the Canadian boreal forest. Boosted regression tree models were built to relate high-resolution data for area burned to an array of explanatory variables describing ignitions, vegetation, and long-term patterns in fire-conducive weather (i.e., fire climate) at four spatial scales (10(2) km(2), 10(3) km(2), 10(4) km(2), and 10(5) km(2)). We evaluated the relative contributions of these controls on area burned, as well as their functional relationships, across spatial scales. We also assessed geographic patterns of the influence of wildfire controls. The results indicated that extreme temperature during the fire season was a top control at all spatial scales, followed closely by a wind-driven index of ease of fire spread. However, the contributions of some variables differed substantially among the spatial scales, as did their relationship to area burned. In fact, for some key variables the polarity of relationships was inverted from the finest to the broadest spatial scale. It was difficult to unequivocally attribute values of relative importance to the variables chosen to represent ignitions, vegetation, and climate, as the interdependence of these factors precluded clear partitioning. Furthermore, the influence of a variable on patterns of area burned often changed enormously across the biome, which supports the idea that fire-environment relationships in the boreal forest are complex and nonstationary.

To ensure that these habitats are conserved, an efficient means of identifying wetlands at risk of conversion is needed, especially in the southern United States where the rate of wetland loss has been highest in recent decades. We used multivariate adaptive regression splines to develop a model to predict the risk of wetland habitat loss as a function of wetland features and landscape context. Fates of wetland habitats from 1992 to 1997 were obtained from the National Resources Inventory for the U. S. Forest Service's Southern Region, and land-cover data were obtained from the National Land Cover Data. We randomly selected 70% of our 40 617 observations to build the model (n 28 432), and randomly divided the remaining 30% of the data into five Test data sets (n 2437 each). The wetland and landscape variables that were important in the model, and their relative contributions to the model's predictive ability (100 largest, 0 smallest), were land-cover/land-use of the surrounding landscape (100.0), size and proximity of development patches within 570 m (39.5), land ownership (39.1), road density within 570 m (37.5), percent woody and herbaceous wetland cover within 570 m (27.8), size and proximity of development patches within 5130 m (25.7), percent grasslands/herbaceous plants and pasture/hay cover within 5130 m (21.7), wetland type (21.2), and percent woody and herbaceous wetland cover within 1710 m (16.6). For the five Test data sets, Kappa statistics (0.40, 0.50, 0.52, 0.55, 0.56; P < 0.0001), area-under-the-receiver-operating-curve (AUC) statistics (0.78, 0.82, 0.83, 0.83, 0.84; P < 0.0001), and percent correct prediction of wetland habitat loss (69.1, 80.4, 81.7, 82.3, 83.1) indicated the model generally had substantial predictive ability across the South. Policy analysts and land-use planners can use the model and associated maps to prioritize at-risk wetlands for protection, evaluate wetland habitat connectivity, predict future conversion of wetland habitat based on projected land-use trends, and assess the effectiveness of wetland conservation programs.

Riparian buffer practices are also considered in this synthesis due to their implementation in wetlands or effects on wetland ecosystem service provisioning when implemented adjacent to wetlands. Conservation practices are most extensive in the first three of the following seven regions analyzed: Mississippi Alluvial Valley, Glaciated Interior Plains, Piedmont-Coastal Plain, Prairie Pothole Region, California Central Valley, Appalachia, and the High Plains. Of the eight dominant practices available to establish and manage wetlands, the three most prevalent are Wetland Establishment, Wetland Management, and Riparian Buffer establishment and management. Differences in physiography among regions strongly influence the types of practices commonly applied. Highly altered drainage patterns and nutrient loading common to agriculture can make wetland establishment difficult. Nutrient enrichment, especially with nitrogen, can create trade-offs between reduced export of nutrients downstream (e. g., nitrate) and enhanced greenhouse gas emissions (e. g., nitrous oxide). Guidance is needed that considers the full array of ecosystem functions and services of multiple practices across a range of spatial scales. Both positive and negative effects need to be addressed given the trade-offs between enhancement of ecosystem services and the lack of knowledge of thresholds at which ecosystem functions are no longer ecologically or economically sustainable. In many cases, data are not presently available, nor is there a suitable monitoring process in place to assess the long-term effects of agriculture on additional wetlands and the potential services they provide, and vice versa. This points to the need to better match practices with goals, to evaluate restoration costs and benefits, and to optimize how decision-making is distributed between national and local levels.

S. Coastal Plain and Piedmont region, diverse inland wetlands (riverine, depressional, wet flats) have been impacted by or converted to agriculture. Farm Bill conservation practices that restore or enhance wetlands can return their ecological functions and services to the agricultural landscape. We review the extent of regional knowledge regarding the effectiveness of these conservation practices. Riparian buffers and wetland habitat management have been the most commonly applied wetland-related practices across the region. Riparian Forest Buffers (RFB) have been most studied as a practice. Water quality functions including pollutant removal, provision of aquatic habitat, and enhanced instream chemical processing have been documented from either installed RFBs or natural riparian forests; forest buffers also serve wildlife habitat functions that depend in part on buffer width and connectivity. Wetland restoration/creation and habitat management practices have been less studied on regional agricultural lands; however, research on mitigation wetlands suggests that functional hydrology, vegetation, and faunal communities can be restored in depressional wetlands, and the wetland habitat management practices represent techniques adapted from those used successfully on wildlife refuges. Other conservation practices can also support wetland services. Drainage management on converted wetland flats restores some water storage functions, and viable wetlands can persist within grazed flats if livestock access and grazing are managed appropriately. Because wetland hydrogeomorphic type influences functions, ecosystem services from conservation wetlands will depend on the specifics of how practices are implemented. In a region of diverse wetlands, evaluation of ecological benefits could be improved with more information on the wetland types restored, created, and managed.

This is especially true within the context of anthropogenic influences, such as land use and climate change. The Conservation Effects Assessment Project-Wetlands National Component (CEAP-Wetlands) was developed by the U. S. Department of Agriculture (USDA) to evaluate effects of conservation practices on ecosystem services including carbon sequestration for climate stability, groundwater recharge, runoff and flood attenuation, water storage, nutrient and contaminant retention, and wildlife habitat. A primary purpose of CEAP-Wetlands is to provide science-based information in an adaptive monitoring framework for use by the USDA to facilitate policy and management decisions, and to document effects of conservation programs and practices to the federal Office of Management and Budget. Herein, we propose a modeling framework to allow estimation of conservation practice and program effects on various ecosystem services at different temporal and spatial scales. This modeling approach provides the broad view needed by decision-makers to avoid unintended negative environmental outcomes, and to communicate to society the positive effects of conservation actions on a broad suite of ecosystem services.

Agricultural activities have documented impacts on the ability of wetlands and other aquatic systems to provide ecosystem services; in order to diminish and/or mitigate these impacts, the Natural Resources Conservation Service (NRCS) carries out resource assessment and place-based conservation planning on agricultural lands. We contend that a comprehensive assessment of the effectiveness of restoration of wetland ecosystem services within an agricultural landscape should include both ecological and socioeconomic metrics, as follows: (1) the amount and type of ecosystem services most at risk, and restored by NRCS conservation program investment; (2) a spatially based assessment of the replacement/addition of ecosystem services from both an ecological and a socioeconomic perspective; and (3) consideration of ecosystem service replacement in context with adjacent land use and population dynamics as a preliminary consideration of differential value. We utilize the Appalachian Region as a demonstration of these necessary elements in assessing the effectiveness of the conservation/restoration investments made over the period of 2000-2006. We identified a total of 1.7 million ha (4.2 million acres) of wetland polygons, with similar to 17% located in an agricultural setting. We developed a classification crosswalk and utilize Hydrogeomorphic Functional Assessment models to demonstrate the relative investment of the 522 583 ha (1 291 330 acres) of wetland-relevant practices across a suite of ecosystem services, with a heavy investment in the nutrient-cycling functions. We examined conservation program implementation in a classification scheme that allocates counties into Urban, Rural, Mixed-Urban, and Mixed-Rural categories based on population characteristics, and assessed the relationship between wetland conservation program application and population dynamics. We found Mixed-Urban and Mixed-Rural counties to have the most wetland in agricultural settings that could be targeted for conservation measures. However, conservation practices have been applied mostly in the Mixed-Rural and Rural counties, indicating a potential overinvestment in the latter. When total acres of conservation measures are examined over a gradient of both urban and total population growth rates, we do not see a concomitant increase in the application of wetland conservation practices, and program investment appears relatively random.

TI Tenderization of beef loins using a high efficiency sparker SO INNOVATIVE FOOD SCIENCE & EMERGING TECHNOLOGIES LA English DT Article DE Beef; Tenderness; High-pressure; Sparker; Shockwaves ID HYDRODYNE PROCESS; SHEAR FORCE; TENDERNESS; STEAKS; BREASTS AB The tenderizing effects of treating beef loins with high-pressure shockwaves from a sparker source were evaluated. Samples were sparker treated as either steaks or intact loin roasts on day 0 and Warner-Bratzler shear force (WBSF) was measured on days 0 and 7. With the sparker head 7.5-cm above the samples, non-aged steaks receiving 80 pulses at two locations had lower WBSF than controls. Aging decreased WBSF in all samples. With the sparker head set at 3.75-cm. treated samples exhibited 20-25% lower WBSF values than controls on day 0 and all of the treated samples demonstrated WBSF reductions >10%. Samples treated as individual steaks and intact loin roasts had similar tenderness improvements. The maximum observed tenderness improvements were 37% (entire steak), 56% (medial portion of steak), and 31% (lateral portion of steak). Data from this study indicate that high-pressure shockwaves generated from a sparker source are an effective postharvest technology for tenderizing beef. Industrial relevance: Improving meat tenderness is essential to enhancing the value and consumer appeal of inferior quality meat cuts. Demonstrating the ability to tenderize tough cuts of meat using sparker generated high-pressure shockwaves is an important step in providing the meat industry with an effective postharvest technology for improving product quality.

The market and welfare effects of MCOOL are shown to be case-specific and dependent on the labeling costs at the farm and retail levels, the strength of consumer preference for domestic products, the market power of retailers, the marketing margin along the supply chain, and the relative costs of imported and domestic products. Simulation results for the U.S. market of fresh apples indicate that domestic producers are the most likely beneficiaries of MCOOL, followed by domestic consumers. Being unable to exercise market power on consumers or suppliers of fresh apples, retailers will lose if the implementation of MCOOL entails fixed costs. Imports of fresh apples decline after MCOOL introduction. C1 [Giannakas, Konstantinos] Univ Nebraska, Dept Agr Econ, Lincoln, NE 68583 USA.

The first concern is associated with the approximation of the variance of an X-ray intensity half-profile by a function of the MFA and the natural variability of the MFA. The second concern is associated with the approximation of the natural variability of the MFA by a function of the MFA. The third concern is associated with the fact that the variance approach was not designed to handle tilt in the fiber orientation. All three concerns are associated with potential biases in MFA estimates. We raise these three concerns so that other researchers interested in understanding, implementing, or extending the variance approach or in comparing the approach to other methods of estimating MFA will be aware of them.

TI LEAF ABSCISSION IN IMPATIENS (BALSAMINACEAE) IS DUE TO LOSS OF HIGHLY DE-ESTERIFIED HOMOGALACTURONANS IN THE MIDDLE LAMELLAE SO AMERICAN JOURNAL OF BOTANY LA English DT Article DE abscission zone; Balsaminaceae; cell wall; Impatiens sultani; homogalacturonan; immunocytochemistry; middle lamellae ID CELL-WALL POLYSACCHARIDES; MONOCLONAL-ANTIBODIES; IMMUNOCYTOCHEMICAL CHARACTERIZATION; ARABIDOPSIS-THALIANA; PEDICEL ABSCISSION; FLOWER ABSCISSION; FOLIAR ABSCISSION; EXPRESSION; POLYGALACTURONASE; LOCALIZATION AB Premise of study: Abscission zones (AZ) are sites where leaves and other organs are shed. Investigating the AZ by classical biochemical techniques is difficult due to its small size and because the surrounding tissue is not involved in abscission. The goals of this study were to determine whether AZ cell walls are chemically unique from the other cells of the petiole, perhaps making them more susceptible to enzymatic degradation during abscission and to identify which cell wall polysaccharides are degraded during abscission. Methods: A battery of antibodies that recognize a large number of cell wall polysaccharide and glycoprotein epitopes was used to probe sections of the Impatiens leaf AZ at several time points in the abscission process. Key results: Prior to abscission, the walls of the AZ cells were found to be similar in composition to the walls of the cells both proximal and distal to the AZ. Of all the epitopes monitored, only the highly de-esterified homogalacturonans (HG) of the middle lamellae were found to be reduced post-abscission and only at the plane of separation. More highly esterified homogalacturonans, as well as other pectin and xyloglucan epitopes were not affected. Furthermore, cellulose, as detected by an endoglucanase-gold probe and cellulose-binding module staining, was unaffected, even on the walls of the cells facing the separation site. Conclusions: In the leaf abscission zone of Impatiens, wall alterations during abscission are strictly limited to the plane of separation and involve only the loss of highly de-esterified pectins from the middle lamellae.

ASTERACEAE AB Premise of the study : Artemisia subgenus Tridentatae plants characterize the North American Intermountain West. These are landscape-dominant constituents of important ecological communities and habitats for endemic wildlife. Together with allied species and genera (Picrothamnus and Sphaeromeria), they make up an intricate series of taxa whose limits are uncertain, likely the result of reticulate evolution. The objectives of this study were to resolve relations among Tridentatae species and their near relatives by delimiting the phylogenetic positions of subgenus Tridentatae species with particular reference to its New World geographic placement and to provide explanations for the relations of allied species and genera with the subgenus with an assessment of their current taxonomic placement. Methods : Bayesian inference and maximum parsimony analysis were based on 168 newly generated sequences (including the nuclear ITS and ETS and the plastid trnS(UGA)-trnfM(CAU) and trnS(GCU)-trnC(GCA)) and 338 previously published sequences (ITS and ETS). Genome size by flow cytometry of species from Sphaeromeria was also determined. Key results : The results support an expanded concept and reconfiguration of Tridentatae to accommodate additional endemic North American Artemisia species. The monotypic Picrothamnus and all Sphaeromeria species appear nested within subgenus Tridentatae clade. Conclusions : A redefinition of subgenus Tridentatae to include other western North American endemics is supported. We propose a new circumscription of the subgenus and divide it into three sections: Tridentatae, Filifoliae, and Nebulosae. The position of the circumboreal and other North American species suggests that subgenus Artemisia is the ancestral stock for the New World endemics, including those native to South America.

TI Plant invasions, generalist herbivores, and novel defense weapons SO ECOLOGY LA English DT Article DE biological invasions; biotic resistance; enemy release; evolution of increased competitive ability; herbivorous invertebrates; novel associations; plant-herbivore interactions ID INCREASED COMPETITIVE ABILITY; EXOTIC PLANTS; NATURAL ENEMIES; BIOLOGICAL-CONTROL; HYPOTHESIS; EVOLUTION; RELEASE; ESCAPE; RESISTANCE; CHEMISTRY AB One commonly accepted mechanism for biological invasions is that species, after introduction to a new region, leave behind their natural enemies and therefore increase in distribution and abundance. However, which enemies are escaped remains unclear. Escape from specialist invertebrate herbivores has been examined in detail, but despite the profound effects of generalist herbivores in natural communities their potential to control invasive species is poorly understood. We carried out parallel laboratory feeding bioassays with generalist invertebrate herbivores from the native (Europe) and from the introduced (North America) range using native and nonnative tetraploid populations of the invasive spotted knapweed, Centaurea stoebe. We found that the growth of North American generalist herbivores was far lower when feeding on C. stoebe than the growth of European generalists. In contrast, North American and European generalists grew equally well on European and North American tetraploid C. stoebe plants, lending no support for an evolutionary change in resistance of North American tetraploid C. stoebe populations against generalist herbivores. These results suggest that biogeographical differences in the response of generalist herbivores to novel plant species have the potential to affect plant invasions.

We characterized a slow (Dicranopteris linearis) and fast-decomposing species (Cheirodendron trigynum) and surface (O), and subsurface (A-horizon) SOM beneath each species using pyrolysis-gas chromatography/mass spectrometry (py-GC/MS), with and without derivatization. The live tissues of Dicranopteris had greater lignin content whereas Cheirodendron had a greater lipid, N-bearing, and polysaccharide component. Despite this difference in leaf chemistry, SOM chemistry was similar between soil aggregate fractions, but different between horizons. The O-horizon contained primarily lignin and polysaccharide biomarkers whereas the A-horizon contained polysaccharide, aromatic, and N-derived compounds, indicating considerable microbial processing of plant litter. The soils beneath Cheirodendron inherited a greater lipid signal composed of cutin and suberin biomarkers whereas the soils beneath Dicranopteris contained greater aromatic biomarker content, possibly derived from plant lignins. The soils beneath both species were more similar to root polysaccharides, lipids, and lignins than above-ground tissue. This study indicates that although plant-derived OM is processed vigorously, species-specific biomarkers and compound class differences persist into these soils and that differences in plant chemical properties may influence soil development even after considerable reworking of plant litter by microorganisms.

The total volume can be converted to total dry weight (biomass) by applying well-known specific gravity relationships and then biomass can be converted to carbon. The suggested method uses importance sampling (IS) and is motivated by the pipe model theory of tree form. The critical assumption is that decurrent form tree crowns can be virtually collapsed into an excurrent form. Subsequently, standard IS ideas can be applied. The proposed tree volume estimator requires measurement of diameters at one or more upper stem heights. The method can be applied to either standing or felled trees.

Most successful entrepreneurs are either scaling down from their forestry and logging backgrounds or scaling up from green industry. They are skilled in some aspects of working with WUIF owners but often need additional tools, including people and marketing skills, business plans based on hourly fee structure, and technical skills such as amenity silviculture and ecology. Successful entrepreneurs emphasize amenity and environmental qualities, offer diverse services and/or are well networked with complementary businesses, have an appropriate suite of equipment, charge by hour and job rather than commission, and have excellent people skills.

M-S funding has helped produce thousands of forestry scientists and other research professionals, and M-S-supported research has provided critical basic understanding and applied solutions to extend the benefits that flow from forests and related rangelands across the nation over time. The 1962 legislation that created the M-S program authorized funding of up to one-half of the funds appropriated for federal forestry research conducted directly by the USDA. Throughout the program's history, however, M-S appropriations have been far below the authorized level. In 2012, the M-S program's 50th anniversary will be celebrated.

The trees can be grown for energy and for traditional uses such as oriented strandboard. Using IMPLAN (Impact Analysis for Planning) software, we modeled the impacts of shifting land use from hay and pasture for cow-calf beef operations to hybrid poplars in northwest and west central Minnesota. Construction of a 5175 million energy conversion facility capable of making 44 million gal of ethanol and 7.6 million gal of mixed alcohols by gasification/catalysis would create 2,412 jobs, with 5158 million in value added. Facility operation, assuming establishment of 200,000 ac of hybrid poplar, did not substantially change the number of jobs relative to using the land for cow-calf operations. However, the SRWC-related jobs would likely be at higher average salary levels and business tax collections would be higher, resulting in a value-added increase of $80 million annually.

As a result, the US Forest Service has been directed to develop policies and procedures far siting wind energy projects. We incorporate geospatial site suitability analysis with applicable policy and management principles to illustrate the use of a Spatial Decision Support System (5055) for evaluating the potential for wind energy development in the national forests. The SDSS is applied in a case study of the Nantahala and Pisgah National Forests (N&PNF), ranked by the National Renewable Energy Laboratory as one of the top 25 national forests for wind energy development based on wind power, distance from transmission lines, distance from major roads, inventoried roadless areas and other specially designated areas, distance from urban areas, and topography (Karsteadt, R. et al. 2005. Assessing the potential for renewable energy on National Forest Systems lands. National Renewable Energy Laboratory and the US For. Serv. Available online at www.nrel.gov/wind/pdfs/36759.pdf; last accessed Mar. 14, 2009). Our analysis further evaluates the N&PNF potential for wind energy development using 16 environmental, construction, land designation, and policy variables. We find that the majority of the N&PF is highly sensitive or exclusionary to wind energy development. Recommendations include the need for agencywide clarification of evaluation criteria for wind energy projects and prioritization of variables for evaluating future wind projects.

We describe the National Greenhouse Gas Inventory and present the sources of our data and methods and the most recent results. Forests and forest products in the United States sequestered more than - 790 million metric in of CO2 equivalent in 2008, on 253 million ha of forestland. This estimate represents a net increase in carbon, including effects of growth, harvests, or other disturbances of forest ecosystems, as well as carbon stored in harvested wood products. Both area and carbon density of these forestlands have increased since 1990, the first year estimates are required. Currently, 89% of net annual sequestration is in the forest ecosystem, and the balance is net carbon addition to harvested wood products.

In this study we collected xylem sap from branches of the tree species Populus tremuloides, Betula papyrifera and Sorbus aucuparia over 3 months. We measured the instantaneous surface tension and followed changes over a period of 0.5-5 h using the pendant drop technique. In all three species the instantaneous surface tension was equal to or within a few percent of that of pure water. Further, in B. papyrifera and S. aucuparia the change over time following drop establishment, although significant, was very small. In P. tremuloides, however, there was a steep decline in surface tension over time that leveled off towards values 21-27% lower than that of pure water. This indicated the presence of surfactants. The values were lower for thinner distal branch segments than for proximal ones closer to the trunk. In some species it appears valid to assume that the surface tension of xylem sap is equal to that of water. However, in branch segments of P. tremuloides close to the terminal bud and hence potentially in other species as well, it may be necessary to take into account the presence of surfactants that reduce the surface tension over time.

The present study amplifies these studies and reveals additional ploidy-flavonoid races, with ploidy levels known to extend from 2x to 12x, and all except 2x and I 2x represented by races with and without 6-methoxylation of flavonol compounds. Results of this study show that diploids across their range have about 113% as much DNA per genuine as do polyploids and that parallel variation in monoploid genuine size between diploids and accompanying polyploids can be shown in different parts of the species' range. Polyploidy, therefore, appears to have developed independently in several areas of the western United States. Hexaploids are generally not as common as octoploids in shadscale, which could be an indication of diploidization of older tetraploid races.

TI CANYON GRASSLAND VEGETATION CHANGES FOLLOWING FIRE IN NORTHERN IDAHO SO WESTERN NORTH AMERICAN NATURALIST LA English DT Article ID YELLOW STARTHISTLE; 2 BUNCHGRASSES; CHEATGRASS; MANAGEMENT; WILDFIRE; WASHINGTON; HISTORY AB Native and nonnative vegetation mosaics are common in western rangelands. If land managers could better predict changes in the abundance of native and nonnative species following disturbances, maintenance of native plant cover and diversity may be improved. In August 2000, during suppression of a wildfire near Lewiston, Idaho, a backing fire burned canyon grassland plots. A previous study had recorded species composition and cover prior to the fire, so we were able to evaluate changes in species composition and abundance on established plots before and after the fire. Overall, summer burning had little effect on the grassland communities. Pseudoroegneria spicata recovered to prefire coverage by the third postfire year In the third postfire year, cover of native and nonnative annual species was significantly greater on burned than unburned sites (P < 0.03). Bromus tectorum cover increased, as expected, on burned plots. Prefire and postfire cover values for Centaurea solstitial's were nearly equal, and there were no significant cover differences between burned and unburned plots in any year. As part of this stud); we also evaluated changes in the cover of dominant native and nonnative species with respect to their prefire send stage on burned and unburned plots. Because our sample sizes were small, we only report community-level trends but suggest that this type of community analysis could make for an interesting future study.

However, return on investment is diminishing and environmental concerns conflict with current input intensive farm practices. Conventional technologies and their application such as crop breeding and management practices have focused on monocultural systems that are dependent on chemical inputs to produce optimum yields. Current profit margins are low or non-existent with these conventional non-sustainable practices and must be changed if the family farm is to survive. We propose an ecologically based approach to farm management that strives to reduce reliance on chemically intensive inputs through better use of multiple attributes inherent within agroecosystems. This approach requires a redirection in the development and application of current and emerging technologies. Examples of redirections in research and development programs for pest management practices, genetic engineering, and precision agriculture necessary to provide a more ecologically-based and sustainable farming approach are illustrated.

ET data are derived from a range of measurement systems including lysimeters, eddy covariance, Bowen ratio, water balance (gravimetric, neutron meter, other soil water sensing), sap flow, scintillometry and even satellite-based remote sensing and direct modeling. All of these measurement techniques require substantial experimental care and are prone to substantial biases in reported results. Reporting of data containing measurement biases causes substantial confusion and impedance to the advancement of ET models and in the establishment of irrigation water requirements, and translates into substantial economic losses caused by misinformed water management. Basic principles of ET measuring systems are reviewed and causes of common error and biases endemic to systems are discussed. Recommendations are given for reducing error in ET retrievals. Upper limits on ET measurements and derived crop coefficients are proposed to serve as guidelines. The descriptions of errors common to measurement systems are intended to help practitioners collect better data as well as to assist reviewers of manuscripts and users of data and derived products in assessing quality, integrity, validity and representativeness of reported information. This paper is the first part of a two-part series, where the second part describes recommendations for documentation to be associated with published ET data. (C) 2011 Elsevier B.V.

TI A first insight into population structure and linkage disequilibrium in the US peanut minicore collection SO GENETICA LA English DT Article DE Peanut; Germplasm; Linkage disequilibrium; SSR ID ARACHIS-HYPOGAEA L.; MULTILOCUS GENOTYPE DATA; ESTIMATING F-STATISTICS; GENETIC DIVERSITY; CULTIVATED PEANUT; SSR MARKERS; MICROSATELLITE MARKERS; GERMPLASM COLLECTION; MOLECULAR DIVERSITY; DOMINANT MARKERS AB Knowledge of genetic diversity, population structure, and degree of linkage disequilibrium (LD) in target association mapping populations is of great importance and is a prerequisite for LD-based mapping. In the present study, 96 genotypes comprising 92 accessions of the US peanut minicore collection, a component line of the tetraploid variety Florunner, diploid progenitors A. duranensis (AA) and A. ipaensis (BB), and synthetic amphidiploid accession TxAG-6 were investigated with 392 simple sequence repeat (SSR) marker bands amplified using 32 highly-polymorphic SSR primer pairs. Both distance-and model-based (Bayesian) cluster analysis revealed the presence of structured diversity. In general, the wild-species accessions and the synthetic amphidiploid grouped separately from most minicore accessions except for COC155, and were eliminated from most subsequent analyses. UPGMA analysis divided the population into four subgroups, two major subgroups representing subspecies fastigiata and hypogaea, a third group containing individuals from each subspecies or possibly of mixed ancestry, and a fourth group, either consisting of COC155 alone if wild species were excluded, or of COC155, the diploid species, and the synthetic amphidiploid. Model-based clustering identified four subgroups- one each for fastigiata and hypogaea subspecies, a third consisting of individuals of both subspecies or of mixed ancestry predominantly from Africa or Asia, and a fourth group, consisting of individuals predominantly of var fastigiata, peruviana, and aequatoriana accessions from South America, including COC155. Analysis of molecular variance (AMOVA) revealed statistically-significant (P < 0.0001) genetic variance of 16.87% among subgroups. A total of 4.85% of SSR marker pairs revealed significant LD (at r(2) >= 0.1). Of the syntenic marker pairs separated by distances < 10 cM, 11-20 cM, 21-50 cM, and > 50 cM, 19.33, 5.19, 6.25 and 5.29% of marker pairs were found in strong LD (P <= 0.01), in accord with LD extending to great distances in self pollinated crops. A threshold value of r(2) > 0.035 was found to distinguish mean r(2) values of linkage distance groups statistically from the mean r(2) values of unlinked markers; LD was found to extend to 10 cM over the entire minicore collection by this criterion. However, there were large differences in r(2) values among marker pairs even among tightly-linked markers. The implications of these findings with regard to the possibility of using association mapping for detection of genome-wide SSR marker-phenotype association are discussed.

Analysis of gene sequences for the D1/D2 domain of the large subunit rRNA, as well as analysis of concatenated gene sequences for the nearly complete nuclear large subunit rRNA, nuclear small subunit rRNA and translation elongation factor 1-alpha, placed the novel species in the family Trichomonascaceae, but showed that it was distinct from all currently recognized genera. The name Spencermartinsiella europaea gen. nov., sp. nov. is proposed to accommodate the new genus and novel species. The novel species could be distinguished from recognized species of neighbouring genera on the basis of standard phenotypic characteristics. The type and isotype strains of Spencermartinsiella europaea are NCAIM Y.01817(T) (=NRRL Y-48265(T) = CBS 11730(T)) and NCAIM Y.01819(I) (=NRRL Y-48266(I)=CBS 117311), respectively.

The Case of Potato Chips SO JOURNAL OF AGRICULTURAL AND RESOURCE ECONOMICS LA English DT Article DE city-demand system; compensating variation; consumer welfare; new brands; virtual prices ID PRODUCT DIFFERENTIATION; DEMAND SYSTEM; EQUATIONS; PRICE AB This study identifies consumer welfare from new brand introductions in the potato chip market. Price and variety effects of new brand introduction are measured by estimating a demand system underlying an expenditure function. Variety effects are positive in most cities, while price effects are generally negative when consumers exhibit some variety preference. Variety effects dominate price effects in most cities; an opposite effect observed in some cities may indicate high entry barriers or joint brand- and price-based marketing strategies. Results indicate that consumers and producers gain from product innovations, but substantial regional variation exists in the distributional effects of new brand introduction.

Data from multi-frequency EMI tools can be inverted to provide quantitative electrical conductivity estimates as a function of depth. In this study, multi-frequency EMI data collected across an abandoned uranium mill site near Naturita, Colorado, USA, are inverted to produce vertical distribution of electrical conductivity (EC) across the site. The relation between measured apparent electrical conductivity (ECa) and hydraulic conductivity (K) is weak (correlation coefficient of 0.20), whereas the correlation between the depth dependent EC obtained from the inversions, and K is sufficiently strong to be used for hydrologic estimation (correlation coefficient of -0.62). Depth-specific EC values were correlated with co-located K measurements to develop a site-specific In(EC)-In(K) relation. This petrophysical relation was applied to produce a spatially detailed map of K across the study area. A synthetic example based on ECa values at the site was used to assess model resolution and correlation loss given variations in depth and/or measurement error. Results from synthetic modeling indicate that optimum correlation with K occurs at similar to 0.5 m followed by a gradual correlation loss of 90% at 2.3 m. These results are consistent with an analysis of depth of investigation (DOI) given the range of frequencies, transmitter-receiver separation, and measurement errors for the field data. DOIs were estimated at 2.0 +/- 0.5 m depending on the soil conductivities. A 4-layer model, with varying thicknesses, was used to invert the ECa to maximize available information within the aquifer region for improved correlations with K. Results show improved correlation between K and the corresponding inverted EC at similar depths, underscoring the importance of inversion in using multi-frequency EMI data for hydrologic estimation.

A novel method was developed to quantify polyphenols or phenolic compounds through direct interactions of polyphenols with Fast Blue BB in an alkaline medium and the absorbance was measured at 420 nm. The gallic acid calibration lines (0-500 mu g/mL) had a linear correlation (R) greater than 0.99 in all analysis. The limit of detection was < 10 mu g/mL and the limit of quantification was 10 mu g/mL. The total phenolics in beverage samples had gallic acid equivalents (GAE) of 168-1868 (Fast Blue BB) and 701390 (Folin-Ciocalteu) mg GAE/100 mL in juices and juice mixes. The solid samples (fresh fruits and dry fruits) were extracted with 70% ethanol and the resulting Fast Blue BB: Folin-Ciocalteu were 37-1291:21-315 and 337-595:399-1036 GAE (mg/100 g) in fresh and dry fruits, respectively. The Fast Blue BB:Folin-Ciocalteu ratios ranged from < 1 to 4.8. The freeze-dried acai powder had 10,000:3000 mg GAE/100 g (Fast Blue BB:Folin-Ciocalteu) while the fresh blueberries had 1291:315 GAE/100 g. The novel method demonstrated that GAE values were higher with Fast Blue BB method than with the Folin-Ciocalteu method. Published by Elsevier Ltd.

The aqueous gel was prepared using Pluronic F127 (18-22%) and Pluronic F68 (3-9%) in a cold method to obtain a proper gelation temperature at 37 degrees C. Viscoelastic properties of the system were measured by rheological measurements and the physicochemical properties were evaluated by MJ-22 Dial-reflex metaloscope and Zetasizer Nano ZS90. The in vitro antimicrobial activity was evaluated by a disk diffusion test, minimum inhibitory concentration, and minimum bactericidal concentration. A temperature-sensitive gel containing silver nanoparticles with 20 wt% F127 and 6 wt% F68 had suitable fluidity at 25 degrees C and was semi-solid at 37 degrees C. Silver nanoparticle size averaged 78.0 nm. The gel optimized formulation achieved a suitable viscosity. The MIC and MBC of the gel ranged from 1.0 to 2.0 mg/L against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. The activity of the gel against these three species was significantly enhanced (p<0.05) compared to 400 mg/L Asimi standard. This optimized silver nanoparticle dosage form demonstrated a high potential for further development for the clinical treatment of bacterial vaginosis.

In both experiments, 7 mo old castrate male goat kids, equally representing the F(1) Boer x Spanish (BoerX; avg wt 21 kg), Kiko x Spanish (KikoX; avg wt 26 kg) and Spanish (avg wt 20 kg) genetic types, were offered chopped alfalfa (Medicago sativa L) hay with an 80% corn (Zea mays L.)-18% soybean [Glycine max (L) Merr.] meal supplement. In Exp. 1, goats were offered alfalfa hay plus supplement at 0.5% BW. Total DMI hay intake among the three breed types was variable, but was higher (P=0.05) for KikoX compared to Spanish; BoerX was intermediate. Apparent in vivo digestibility coefficients for DM, OM, N, NDF, and ADF were not different (P > 0.10). Blood glucose concentrations were similar for Spanish and KikoX (mean 70.3 mg/dl), but both were higher (P < 0.01) compared to BoerX (62.6 mg/dl). In Exp. 2, goats were offered alfalfa hay plus the same supplement at 2% BW. Hay DMI (mean 2.46% BW) and total DMI (mean 4.26% BW) were not different among genetic types. Beginning and ending BW were greater (P < 0.001) for KikoX compared to BoerX; both were greater than Spanish, but ADG were similar (P > 0.10) among breeds (93 g/d). More research is needed that evaluates forage-supplement interactions, metabolic differences, and physiological changes among meat goats in order to optimize nutrient-use efficiency and performance.

Plants rich in condensed tannins (CT) can have beneficial anthelmintic properties. Peanut (Arachis hypogea L) skins (testa), an agricultural by-product, are a rich source of CT, have low fiber and high levels of oil and crude protein, and have been incorporated into feed products for the cattle industry. Anthelmintic activity of pellets formulated with peanut skins was compared to that of commercial alfalfa (Medicago sativa L) pellets (control diet) fed to lambs in two separate experiments, one with initially low (220 eggs g(-1) feces; 2008) and the other high (4260 eggs g(-1) feces: 2009) burden of GIN. In both experiments lambs were maintained on bermudagrass (Cynodon dactyon (L) Pers.) pastures except when pellets were fed (six lambs per treatment) at 2.3% BW every other day three times a week. Overall, average daily intake of CT as quebracho (Schinopsis sp.) equivalents of peanut skin pellets formulated with 5% molasses was 0.38% BW (low GIN lambs), and that of peanut skin pellets formulated with 48% alfalfa and 7% molasses was 0.53% BW (high GIN lambs). Regardless of the initial level of GIN burden and the formulation of the peanut skin pellets, average daily weight gain of all lambs was about 94 +/- 7.2 g per day. Increases in fecal egg count and decreases in blood packed cell volumes that occurred during the trials were not significantly different (P > 0.05) between lambs fed the control alfalfa pellets and lambs fed peanut skin containing pellets. In these trials, intake of peanut skin may have been insufficient to decrease GIN parasite activity, or perhaps the low prodelphinidin subunit composition of CT in peanut skin prevented a beneficial response.

Merr.] plants and is known to cause yellowing in soybean. Although, AMPA is less phytotoxic than glyphosate, its mode of action is different from that of glyphosate and is still unknown. Greenhouse studies were conducted at Stoneville, MS to determine the effects of AMPA on plant growth, chlorophyll content, photosynthesis, nodulation, nitrogenase activity, nitrate reductase activity, and shoot nitrogen content in GR and GS soybeans. AMPA was applied to one- to two-trifoliolate leaf stage soybeans at 0.1 and 1.0 kg ha(-1), representing a scenario of 10% and 100% degradation of glyphosate (1.0 kg ae ha(-1) use rate) to AMPA, respectively. Overall, AMPA effects were more pronounced at 1.0 kg ha(-1) than at 0.1 kg ha(-1) rate. Visual plant injury (18-27%) was observed on young leaves within 3 d after treatment (DAT) with AMPA at the higher rate regardless of soybean type. AMPA injury peaked to 46-49% at 14 DAT and decreased to 17-18% by 28 DAT, in both soybean types. AMPA reduced the chlorophyll content by 37%, 48%, 66%, and 23% in GR soybean, and 17%, 48%, 57%, and 22% in GS soybean at 3, 7, 14, and 28 DAT, respectively. AMPA reduced the photosynthesis rate by 65%, 85%, and 77% in GR soybean and 59%, 88%, and 69% in GS soybean at 3, 7, and 14 DAT, respectively, compared to non-treated plants. Similarly, AMPA reduced stomatal conductance to water vapor and transpiration rates at 3, 7, and 14 DAT compared to non-treated plants in both soybean types. Photosynthesis rate, stomatal conductance, and transpiration rate recovered to the levels of non-treated plants by 28 DAT. Plant height and shoot dry weight at 28 DAT; nodulation, nitrogenase activity at 10 DAT, and nitrate reductase activity at 3 and 14 DAT were unaffected by AMPA. AMPA reduced root respiration and shoot nitrogen content at 10 DAT. These results suggest that a foliar application of AMPA could indirectly reduce photosynthesis through decreased chlorophyll content in GR and GS soybean up to 14 DAT, but affected plants can recover to normal growth by 28 DAT.

Our aim was to determine if two single nucleotide polymorphisms (SNPs) located in NOS3 (E298D and i19342) interfere with microvascular endothelial function (MEF) and/or oxidative stress during the postprandial state. Methods: MEF was assessed with laser Doppler flowmetry at baseline and 2, 4, 6 and 8 h after ingestion of a single fatty meal (60% fat, 15% proteins and 25% carbohydrates) by 40 healthy young males. Oxidative stress was measured by nitrites/nitrates and oxidized LDL (LDL-ox) concentrations in fasting and postprandial states. Results: Postprandial MEF was impaired in the carriers of minor alleles of the SNPs (global mean 60.99% Vs 87.25%, p = 0.016 for i19342; 63.62% Vs 95.71%, p = 0.011 for E298D). Carriers of E298D showed a higher LDL-ox at fasting and postprandial measures, and lower nitrites/nitrates at fasting. Conclusions: Minor allele carriers for E298D and i19342 have an impaired postprandial MEF and increased oxidative stress. Our results both provide insight into the higher risk of CVD attributed to E298D and identify variants that affect MEF in a healthy population.

(Amaryllidaceae) species using random amplification of polymorphic DNA (RAPD) markers. Also, single nucleotide polymorphisms (SNPs) of internal transcribed spacer 1, 5.8S ribosomal RNA gene and internal transcribed spacer 2 regions in Lycoris sanguinea var. koreana were analyzed. All accessions formed 6 major clusters; cluster A with all L. sanguinea and L. chejuensis; cluster B with 3 accessions of L. flavescens; cluster C with 8 accessions of F. flavescens var. flavescens; cluster D with 10 accessions of L. uydoensis; cluster E with L. chinensis var. sinuolata and 4 accessions of L. uydoensis; and cluster F with all L. radiata. Five haplotypes were observed; L. sanguinea and L. chejuensis having the haplotype 1 with bases of CTTATATATAT; L. chinensis var. sinuolata and all L. flavescens. Lycoris incarnata and L. aurea, non-endemic to Korea had haplotype 2 and 5, respectively. Genetic variations in L. flavescens, L. chinensis var. sinuolata, and L. uydoensis are revealed based on the analysis of molecular variances (AMOVA) and haploid types analyzed by sequence analysis. It is suggested that L. chejuensis may result from hybridization involving L. sanguinea var. koreana due to a close affinity between L. sanguinea complex and L. chejuensis. Nomenclature for L. chejuensis and L. flavescens whether they should be described as a hybrid origin should be discussed in the future.

In winter, the plots were either covered with a non-woven rowcover (RC) or left uncovered. Cane injury was least in plants with lateral canes oriented horizontally and covered. Cane injury was high in plants with lateral canes oriented vertically in winter, whether covered or not, and among plants with lateral canes laid close to the ground but not covered. Among 'Siskiyou' plants that had lateral canes oriented horizontally, 280 flower clusters and 6.0 kg fruit/plant were produced on plants that had a RC in the winter compared with only 72 flower clusters and 1.7 kg fruit/plant for plants that were not covered in winter, in 2009. Fewer flower clusters developed and the yield was <= 2 kg/plant on plants with lateral canes oriented vertically. Yield differences between the most and least productive treatments were low in 2010 because of milder winter conditions and snowfall during the coldest periods that fully or partially covered the lateral canes oriented horizontally and close to the ground. The RC treatment had no effect on cane injury or yield when lateral canes were oriented vertically. The findings suggested that 'Siskiyou' blackberry can be grown in the eastern United States, where winter injury has frequently caused a crop failure, by positioning the lateral canes close to the ground and covering plants with a RC.

In N-limited watersheds, discharge of N from production areas can have negative impacts on nontarget aquatic systems. This study monitored nitrate-N concentrations in production area drainage water originating from a foliage plant production area. Concentrations in drainage water were monitored during the transition from 100% reliance on fertigation using urea and nitrate-based soluble formulations (SF) to a nitrate-based controlled-release formulation (CRF). During the SF use period, nitrate-N concentrations ranged from 0.5 to 322.0 mg.L(-1) with a median concentration of 31.2 mg.L(-1). Conversely, nitrate-N concentrations during the controlled-release fertilization program ranged from 0 to 147.9 mg-L(-1) with a median concentration of 0.9 This project demonstrates that nitrate-N concentrations in drainage water during the CRF program were reduced by 94% to 97% at the 10th through 95th percentiles relative to the SF fertilization program. Nitrate-N concentrations in drainage water from foliage plant production areas can be reduced by using CRF fertilizer formulations relative to SF formulations/fertigation. Similar results should be expected for other similar containerized crops. Managers located within N-limited watersheds facing N water quality regulations should consider the use of CRF fertilizer formulations as a potential tool (in addition to appropriate application rates and irrigation management) for reducing production impacts on water quality.

TI Blackberry Propagation by Non-leafy Floricane Cuttings SO HORTTECHNOLOGY LA English DT Article DE Rubus; adventitious root; cytokinin; axillary bud; enclosure system ID THORNLESS BLACKBERRY; BUD DEVELOPMENT; TEMPERATURE AB One-or two-node hardwood cuttings were taken from 9-year-old 'Triple Crown' and 'Siskiyou' blackberry (Rubus) plants on 5 Nov. 2009, 3 Dec. 2009, and 21 Jan. 2010. The response of cuttings with and without partially excised axillary buds to an application of cytokinin was compared with control cuttings with intact axillary buds and no cytokinin. Differences in root development were evident in the two cultivars tested. The cuttings of 'Siskiyou' and 'Triple Crown' callused on cut ends, but many of the adventitious roots developed from the base of the axillary buds. Shoots emerged from the bud in, approximate to 90% of 'Siskiyou' cuttings stuck in November, December, and January. Rooting occurred in more than 90% of cuttings stuck in November and December but declined in cuttings stuck in January. In `Siskiyou', bud excision had no effect on shoot and root emergence, but cytokinin treatment suppressed rooting in cuttings collected in November and January. Shoot emergence and rooting were poorer in 'Triple Crown' cuttings than in 'Siskiyou'. In 'Triple Crown' cuttings, partial excision of buds reduced shoot emergence only in January but had no effect on rooting at three sticking dates. Cytokinin treatment improved shoot emergence in November and December but reduced rooting in January. The enclosed system is a viable method for propagating `Siskiyou' blackberry by non-leafy floricane cuttings.

The long-term efficacy of management strategies for suppressing this disease in both aquaculture and restoration settings depends on the potential rate of evolutionary response by P. marinus. Sexual reproduction has never been demonstrated in vitro or in previous population genetic studies. We developed high resolution microsatellite markers and amplified alleles directly from infected oyster genomic DNA. Of 336 infected oysters from four populations between Massachusetts and Florida, 129 (48%) appeared to be infected with a single parasite genotype and were subjected to population genetic analyses assuming diploidy. The great diversity of multilocus genotypes observed is incompatible with strictly clonal reproduction. Substantial heterozygote deficits in three populations suggest that sexual reproduction often involves inbreeding. At the same time, significant multilocus linkage disequilibrium occurred in most sampled populations, and several genotypes were sampled repeatedly in each of two populations, indicating that asexual reproduction also occurs in P. marinus populations. Interestingly, where this parasite has recently expanded its range, lower strain diversity, significant heterozygote excess, and highly heterozygous multilocus genotypes suggests clonal propagation of recent recombinants. Taken together, these data suggest that P. marinus employs multiple reproductive modes, and that over the short term, selection acts upon independent parasite lineages rather than upon individual loci in a cohesive, interbreeding population. Nevertheless, high genotypic diversity is the evolutionary legacy of sex in P. marinus. Anthropogenic movement of infected oysters may increase outcrossing opportunities, potentially facilitating rapid evolution of this parasite. (c) 2011 Elsevier B.V. All rights reserved.

The present study was undertaken to investigate the effect of boric acid on the levels of piperidine alkaloids in ant venom was investigated. Exposure to boric acid for a period of 4 wks resulted in significant changes in both concentrations and ratios of the piperidine alkaloids. The concentration of piperidine alkaloids was significantly lower in colonies treated with the boric acid bait. Thus, boric acid suppresses the production of piperidine alkaloids in red imported fire ants. C1 [Rojas, M.

Treatments were applied 4 times at approx. 6-wk intervals between May and November 2008. Five treatments were evaluated: ground application (soil drench), foliar application, ground and foliar applications combined, water-only (soil drench), and untreated. Two response variables were measured: yield of oleoresin accumulated at 48 h from wounds inflicted at breast height (5 sample periods) and area of lesion formed in response to inoculation with Ophiostoma minus (Hedgcock) Sydow & P. Sydow (2 sample periods). One treatment, ground application of Beyond, resulted in a significant increase in oleoresin yield (about 40% experiment-wide). Foliar treatment alone, or combined with ground application, did not result in a significant change in oleoresin yield. None of the treatments resulted in a difference in lesion area produced in response to inoculation with O. minus. In summary, application of a commercially-prepared chitosan formulation to loblolly pine produced inconsistent responses in tree parameters associated with bark beetle resistance, suggesting that exogenously applied chitosan preparations have limited utility for managing bark beetles.

Previous studies examining trap capture of these stink bugs have used either laboratory-prepared dispensers or commercial dispensers with various known and unknown pheromone doses. We compared trap captures of E. servus and E. tristigmus using yellow pyramid traps baited with a range of pheromone doses (20 - 120 mu L) loaded onto rubber septa and when baited with 2 commercially available pheromone dispensers. These baited traps were located primarily in or alongside pecan orchards with one exception being alongside a peach/plum orchard. Traps were monitored weekly for 4 wk during 2008 and 2009. Dispensers were either replaced weekly or the same dispenser remained in use for the entire study. All pheromone doses tested resulted in a numerical increase of both E. servus and E. tristigmus captured in traps compared with traps using no pheromone. In each experiment for each species, at least one pheromone dose significantly increased trap capture compared with traps using a septa containing no pheromone. In direct comparisons, neither commercial dispenser ever captured significantly more E. servus or E. tristigmus than traps without pheromone. Numerically higher trap captures were observed with a higher pheromone dose in each of 5 month-long studies. However, captures were not always significantly higher for either species suggesting that other factors affected stink bug capture in pheromone-baited traps. Results from this study could facilitate the use of this stink bug trap as a barrier to impede movement of pest Euschistus spp. into orchards or other crop habitats.

TI Temporal Patterns of Oak Mortality in a Southern Appalachian Forest (1991-2006) SO NATURAL AREAS JOURNAL LA English DT Article DE mortality patterns; oak decline; oak-dominated forest; oak mortality; windthrow ID SOUTHEASTERN UNITED-STATES; NORTHERN ARKANSAS; DECLINE; MOUNTAINS; WIND AB The sustainability of eastern oak-dominated forests is threatened by high oak mortality rates and widespread oak regeneration failure, and presents a challenge to natural area managers. We tracked the rate and cause of mortality of 287 mature oak trees of five species for 15 years to determine the temporal patterns and sources of mortality. We observed a 15.3% total mortality rate during the study period. Mortality was due to oak decline (7.3% of trees) and high-intensity wind events (6.6% of trees). Decline-related mortality was gradual, averaging 0.5% annually. Windthrow was episodic, occurring during hurricane-related weather events in 1995 and 2004. Within species, total mortality was disproportionately high for scarlet oak (Quercus coccinea Muenchh) (41.2%) compared to other species in the red oak group (13.8% for northern red oak (Q. rubra L.); 12.5% for black oak (Q. velutina Lam.)) or the white oak group (10.4% for white oak (Q. alba L.); 5.7% for chestnut oak (Q. prinus L.)). Decline-related mortality was highest for scarlet oak (15.7%) followed by black oak (8.3%), white oak (7.5%), northern red oak (6.9%), and chestnut oak (2.3%). Within the red oak group, the average age of decline-affected and surviving trees did not differ, but average dbh of decline-affected trees was smaller. Decline-affected trees in the white oak group were on average older, but average dbh did not differ from surviving trees. Wind-related mortality also was higher for scarlet oak (21.6%) than for northern red oak (5.2%), black oak (4.2%), white oak (3.0%) or chestnut oak (2.3%). Windthrown red oaks were smaller than survivors, but windthrown trees in the white oak group did not differ in size from survivors. Average age did not differ between windthrown and surviving trees for either group. Oak mortality rates observed in this study, coupled with oak regeneration failure, could result in a substantial reduction in the proportion of mature canopy oaks and change the relative abundance of oak species in southern Appalachian forests over the long-term.

TI Rehabilitating Slash Pile Burn Scars in Upper Montane Forests of The Colorado Front Range SO NATURAL AREAS JOURNAL LA English DT Article DE exotic plants; pile burning; rehabilitation techniques; soil nitrogen; understory ID NATIONAL-PARK; FIRE; COMMUNITIES; SEVERITY; WILDFIRE; IMPACTS; CARBON AB Slash pile burning is widely conducted by land managers to dispose of unwanted woody fuels, yet this practice typically has undesirable ecological impacts. Simple rehabilitation treatments may be effective at ameliorating some of the negative impacts of pile burning on plants and soils. Here, we investigated: (1) the impacts of slash pile burning on soil nitrogen and understory plant species richness and cover in Colorado Pinus conform Douglas ex Louden and P contorta - Populys tremuloides Michx. stands; (2) the effectiveness of woodchip mulch and soil scarification at reversing pile burning impacts on soil nitrogen; and (3) how mulching and scarifying, alone and in conjunction with native grass seeding, promote native plant establishment and discourage exotic invasion in burn scars. We found that pile burning diminished native richness and cover and increased soil nitrogen, particularly in the interior of burn scars where fire severity was greatest. Rehabilitation treatments appear to be useful tools for reversing pile burning impacts on soil and plants. Mulching dampened the increase in soil nitrogen; and scarifying, scarifying plus seeding, and mulching plus seeding were effective at encouraging native plant development while simultaneously minimizing exotic plant colonization.

PHOSPHORUS LIMITATION; SHRIMP POND EFFLUENT; STABLE-ISOTOPE; WATER-QUALITY; RIVER ESTUARY; NITROGEN; NUTRIENT; COASTAL; FLORIDA AB The coastal red mangrove, Rhizophora mangle L., was introduced to the Hawaiian Islands from Florida 100 yr ago and has spread to cover many shallow intertidal shorelines that once were unvegetated mudflats. We used a field survey approach to test whether mangroves at the land-ocean interface could indicate watershed inputs, especially whether measurements of leaf chemistry could identify coasts with high nutrient inputs and high mangrove productivities. During 2001-2002, we sampled mangroves on dry leeward coasts of southern Moloka'i and O'ahu for 14 leaf variables including stable carbon and nitrogen isotopes (delta C-13, delta N-15) macronutrients (C, N, P), trace elements (B, Mn, Fe, Cu, Zn), and cations (Na, Mg, K, Ca). A new modeling approach using leaf Na, N, P, and PC indicated two times higher productivity for mangroves in urban versus rural settings, with rural mangroves more limited by low N and P nutrients and high-nutrient urban mangroves more limited by freshwater inputs and salt stress. Leaf chemistry also helped identify other aspects of mangrove dynamics: especially leaf delta N-15 values helped identify groundwater N inputs, and a combination of strongly correlated variables (C, N, P, B, Cu, Mg, K, Ca) tracked the mangrove growth response to nutrient loading. Overall, the chemical marker approach is an efficient way to survey watershed forcing of mangrove forest dynamics.

The developed regression model showed a highly significant relationship (R(2)=0.99) between the L*a*b* values and the amylose content. Apparent amylose content was strongly and negatively correlated with L*a*b* values. This method could be used to predict amylose content in rice. The conversion of L*a*b* values to red, green, blue (RGB) values and to color hexadecimal codes allowed reproducing the colors of starch-iodine solution and making an explicit color board. Using this specific color board, we could sort entries into their respective classes and easily estimate their apparent amylose content.

The scFvs, m1C3, m4B7, and m2A10, are derived from mouse monoclonal antibodies that inhibit either ookinete invasion of the midgut or sporozoite invasion of salivary glands. The scFvs that target the parasite surface, m4B7 and m2A10, were fused to an Anopheles gambiae antimicrobial peptide, Cecropin A. Previously-characterized Anopheles cis-acting DNA regulatory elements were included in the transgenes to coordinate scFv production with parasite development. Gene amplification and immunoblot analyses showed promoter-specific increases in transgene expression in blood-fed females. Transgenic mosquito lines expressing each of the scFv genes had significantly lower infection levels than controls when challenged with P. falciparum.

Martini, Ashlie TI Calculation of single chain cellulose elasticity using fully atomistic modeling SO TAPPI JOURNAL LA English DT Article ID MOLECULAR-DYNAMICS SIMULATIONS; I-BETA; X-RAY; CRYSTALLINE; SYSTEM AB Cellulose nanocrystals, a potential base material for green nanocomposites, are ordered bundles of cellulose chains. The properties of these chains have been studied for many years using atomic-scale modeling. However, model predictions are difficult to interpret because of the significant dependence of predicted properties on model details. The goal of this study is to begin to understand these dependencies. We focus on the investigation on model cellulose chains with different lengths and having both periodic and nonperiodic boundary conditions, and predict elasticity in the axial (chain) direction with three commonly used calculation methods. We find that chain length, boundary conditions, and calculation method affect the magnitude of the predicted axial modulus and the uncertainty associated with that value. Further, the axial modulus is affected by the degree to which the molecule is strained. This result is interpreted in terms of the bonded and nonbonded contributions to potential energy, with a focus on the breaking of hydrogen bonds during deformation.

TI Improved modeling of soil organic carbon in a semiarid region of Central East Kazakhstan using EPIC SO AGRONOMY FOR SUSTAINABLE DEVELOPMENT LA English DT Article DE EPIC model; Kazakhstan; steppe; soil organic carbon ID LONG-TERM EXPERIMENTS; PRODUCTIVITY; DYNAMICS; GIS; SEQUESTRATION; UNCERTAINTY; IMPACTS AB Inappropriate land use and soil mismanagement produced wide-scale soil and environmental degradation to the short-grass steppe ecosystem in the semiarid region of central east Kazakhstan. A limitation for determining the impacts of land use changes on soil organic carbon (SOC) is the dearth of information on SOC stocks under the predominant land uses in the region. Here we used the Environmental Policy Integrated Climate (EPIC) model to study long-term impacts of land use changes and soil management on SOC to a depth of 50 cm during 1955-2030, in degraded agricultural lands of central east Kazakhstan. Simulated land uses were: native rangeland vegetation, wheat (Triticum aestivum L.), wheatgrass (Agropyron cristatum L.), and abandoned croplands. The EPIC model was initialized with soil properties obtained from a soil map of the study area. Data on crop management, fertilizer application and tillage practices were gathered from local expert knowledge. Simulations were performed for each polygon on a land use classification map, resulting in 4661 simulations. Our results showed that simulated SOC explained 50% of the variation in measured SOC. Of the 1.38 million hectares in the study area, 78% were under native vegetation, 3% cultivated to wheat, 8% on wheatgrass, and 11% were abandoned croplands in 2005. If land use remained constant, total stock of SOC would decrease at an annual rate of 723 kg C ha(-1). However, if best management practices are implemented, resulting in reallocation of land use according to the land capability with abandoned croplands being converted to reduced-tillage wheat or wheatgrass, total stock of SOC would increase to an equivalent of 4700 kg C ha(-1) yr(-1). Combining land use classification and soil maps with EPIC, proved valid for studying impacts of land use changes and management practices on SOC; an important aspect of this approach is the ability to scale up site-specific SOC to the region. With the available data, EPIC produced relatively accurate results but more data on spatial and temporal variation in SOC are needed to improve model calibration and validation.

TI Prevalence, Distribution, and Diversity of Salmonella enterica in a Major Produce Region of California SO APPLIED AND ENVIRONMENTAL MICROBIOLOGY LA English DT Article ID ESCHERICHIA-COLI O157-H7; FIELD GEL-ELECTROPHORESIS; UNITED-STATES; FRESH PRODUCE; CATTLE; OUTBREAKS; SEROVAR; SAMPLES; NEWPORT; FECES AB A survey was initiated to determine the prevalence of Salmonella enterica in the environment in and around Monterey County, CA, a major agriculture region of the United States. Trypticase soy broth enrichment cultures of samples of soil/sediment (n = 617), water (n = 252), wildlife (n = 476), cattle feces (n = 795), and preharvest lettuce and spinach (n = 261) tested originally for the presence of pathogenic Escherichia coli were kept in frozen storage and later used to test for the presence of S. enterica. A multipathogen oligonucleotide microarray was employed to identify a subset of samples that might contain Salmonella in order to test various culture methods to survey a larger number of samples. Fifty-five of 2,401 (2.3%) samples yielded Salmonella, representing samples obtained from 20 different locations in Monterey and San Benito Counties. Water had the highest percentage of positives (7.1%) among sample types. Wildlife yielded 20 positive samples, the highest number among sample types, with positive samples from birds (n = 105), coyotes (n = 40), deer (n = 104), elk (n = 39), wild pig (n = 41), and skunk (n = 13). Only 16 (2.6%) of the soil/sediment samples tested positive, and none of the produce samples had detectable Salmonella. Sixteen different serotypes were identified among the isolates, including S. enterica serotypes Give, Typhimurium, Montevideo, and Infantis. Fifty-four strains were sensitive to 12 tested antibiotics; one S. Montevideo strain was resistant to streptomycin and gentamicin. Pulsed-field gel electrophoresis (PFGE) analysis of the isolates revealed over 40 different pulsotypes. Several strains were isolated from water, wildlife, or soil over a period of several months, suggesting that they were persistent in this environment.

TI Isolation of Lactobacillus salivarius 1077 (NRRL B-50053) and Characterization of Its Bacteriocin, Including the Antimicrobial Activity Spectrum SO APPLIED AND ENVIRONMENTAL MICROBIOLOGY LA English DT Article ID LACTIC-ACID BACTERIA; CAMPYLOBACTER-JEJUNI; PURIFICATION; COLONIZATION; CHICKENS; STRAIN; FOOD AB Lactobacillus salivarius 1077 (NRRL B-50053) was isolated from poultry intestinal materials, and in vitro anti-Campylobacter jejuni activity was demonstrated. The isolate was then used for bacteriocin production and its enrichment. The protein content of the cell-free supernatant from the spent medium was precipitated by ammonium sulfate and dialyzed to produce the crude antimicrobial preparation. A typical bacteriocin-like response of sensitivity to proteolytic enzymes and resistance to lysozyme, lipase, and 100 degrees C was observed with this preparation. The polypeptide was further purified by gel filtration, ion-exchange, and hydrophobic-interaction chromatography. Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), Edman degradation, and isoelectrofocusing were used to characterize its 3,454-Da molecular mass, the amino acid sequence of its 37 residue components, and the isoelectric point of pI 9.1 of the bacteriocin. Bacteriocin L-1077 contained the class IIa bacteriocin signature N-terminal sequence YGNGV. MICs of bacteriocin L-1077 against 33 bacterial isolates (both Gram negative and Gram positive) ranged from 0.09 to 1.5 mu g/ml. Subsequently, the therapeutic benefit of bacteriocin L-1077 was demonstrated in market-age (40- to 43-day-old) broiler chickens colonized with both C. jejuni and Salmonella enterica serovar Enteritidis. Compared with untreated control birds, both C. jejuni and S. Enteritidis counts in colonized ceca were diminished by >4 log(10) and S. Enteritidis counts in both the liver and the spleen of treated birds were reduced by 6 to 8 log(10)/g compared with those in the nontreated control birds. Bacteriocin L-1077 appears to hold promise in controlling C. jejuni/S. Enteritidis among commercial broiler chickens.

Gravett, Alan TI Preparation of Fatty Acid Methyl Esters from Osage Orange (Maclura pomifera) Oil and Evaluation as Biodiesel SO ENERGY & FUELS LA English DT Article ID SUPERCRITICAL-FLUID EXTRACTION; VEGETABLE-OILS; SEED OIL; FRACTIONATION; FUEL AB Fatty acid methyl esters were prepared in high yield by transesterification of osage orange (Madura pomifera L.) seed oil. The crude oil was extracted using supercritical CO(2) and was initially treated with mineral acid and methanol to lower its content of free fatty acids, thus rendering it amenable to homogeneous, alkali-catalyzed methanolysis. The principle components identified in osage orange methyl esters (OOMEs) were methyl linoleate (76.4%), methyl oleate (11.9%), methyl palmitate (7.0%), and methyl stearate (2.4%). As a result of the high content of methyl linoleate, OOMEs exhibited cetane number (44.9) and induction period (IP; 2.4 h) values below the ranges specified in the biodiesel standards ASTM D6751 and EN 14214. The addition of 500 ppm tert-butylhydroquinone (TBHQ) resulted in a higher IP (6.4 h) compliant with the biodiesel standards. Furthermore, the high content of methyl linoleate resulted in an iodine value (IV; 144 g of I(2)/100 g) in excess of the maximum limit specified in EN 14214. The acid value (AV), glycerol content, kinematic viscosity, moisture content, phosphorus content, and sulfur content of OOMEs were within the limits prescribed ill ASTM D6751 and EN 14214. In addition, data collected for density, lubricity, and energy content were typical for biodiesel fuels. The cold-flow properties of OOMEs were superior to those reported for several other biodiesel fuels. Also investigated were B5 and B20 blends of OOMEs in petrodiesel, which yielded AVs, kinematic viscosities, moisture contents, sulfur contents, lubricities, and densities within the limits prescribed in the petrodiesel standards. The addition of 500 ppm. TBHQ to the blends resulted in IPs above the minimum thresholds specified in ASTM D7467 and EN 590. In summary, osage orange seeds provide a low-cost, non-food, high-oil-producing feedstock suitable for production of biodiesel.

TI Evaluation of the Effect of Gallium Maltolate on Fecal Salmonella Shedding in Cattle SO JOURNAL OF FOOD PROTECTION LA English DT Article ID IRON-METABOLISM; INFECTION; CULTURE; ACIDS AB Strategies aimed at reducing fecal shedding of Salmonella and other foodborne pathogens may be effective for limiting transmission of pathogens from food animals to humans. The objective of this study was to determine the effectiveness of gallium maltolate (GaM) against Salmonella in vitro and to determine whether oral administration of GaM would reduce fecal shedding of Salmonella in cattle. Gallium is a semimetal exhibiting antimicrobial properties against some pathogenic bacteria, including Salmonella, by exploiting their need for iron to survive and replicate. In vitro growth studies were performed in pure cultures of Salmonella and in mixed cultures from ruminal fluid. Inclusion of GaM in culture medium or in mixed cultures of ruminal fluid resulted in a significant reduction in growth of Salmonella, suggesting that GaM may be effective for limiting growth and survival in vivo. Therefore, we subsequently administered two doses of GaM to Holstein steers, experimentally infected them with Salmonella, and quantitatively and qualitatively monitored fecal shedding at 12-h intervals. Sixty hours after beginning treatment, cattle were euthanized, and luminal contents and tissue were aseptically harvested from the rumen, jejunum, spiral colon, cecum, and rectum. The luminal contents were processed for quantitative and qualitative analysis of the challenge strains of Salmonella, and tissue samples were enriched and plated for qualitative analysis. We found no significant differences between control and treated animals in quantitative levels of Salmonella in the feces or the luminal contents. Likewise, we observed no pattern between control and treated animals in the frequency of positive or negative results from enriched feces, luminal contents, or tissue samples. These results suggest that GaM was not effective for reducing Salmonella in cattle. C1 [Nerren, J. R.; Edrington, T. S.; Farrow, R. L.; Genovese, K. G.; Callaway, T. R.; Anderson, R. C.; Krueger, N.

The objective of this study was to examine the effect of salt, sodium pyrophosphate (SPP), and sodium lactate on the probability of growth of E. coli O157:H7 in ground beef under a temperature abuse condition. Ground beef containing 0 to 2.25% salt, 0 to 0.5% SPP, and 0 to 3% lactate was inoculated with a four-strain mixture of E. coli O157:H7, vacuum packaged, and stored at 10 C for 15 days. A total of 25 combinations of the three additives, each with 20 samples, were tested. A logistic regression was used to model the probability of growth of E. coli O157:H7 (with a 1.0-log CFU/g increase during storage) as a function of salt, SPP, and lactate. The resultant probability model indicated that lactate at higher concentrations decreased the probability of growth of E. coli O157:H7 in ground beef, and the effect was more pronounced at higher salt concentrations. At salt concentrations below 1.3%, the increase of SPP concentration marginally increased the growth probabilities of E. coli O157:H7. The model illustrated the effect of salt, SPP, and lactate on the growth probabilities and growth or no-growth behavior of E. coli O157:H7 in ground beef and can be used to improve the microbial food safety of ground beef products.

TI Inactivation of Avirulent Yersinia pestis in Beef Bologna by Gamma Irradiation SO JOURNAL OF FOOD PROTECTION LA English DT Article ID ESCHERICHIA-COLI O157-H7; RADIATION-RESISTANCE; LISTERIA-MONOCYTOGENES; TEMPERATURE; ENTEROCOLITICA; SURVIVAL; PLAGUE AB Yersinia pestis, a psychrotrophic pathogen capable of growth at refrigeration temperatures, can cause pharyngeal and gastrointestinal plague in humans that consume contaminated foods. Because Y. pestis is listed as a select agent for food safety and defense, evaluation of food safety intervention technologies for inactivation of this pathogen is needed. Ionizing (gamma) radiation is a safe and effective intervention technology that can inactivate pathogens in raw and processed meats, produce, and seafood. In this study, we investigated the effect of temperature on the ability of ionizing radiation to inactivate avirulent Y. pestis in beef bologna. The mean (+/- standard error of the mean) radiation D(10)-values (the radiation dose needed to inactivate 1 log unit or 90% of the population of a microorganism) for avirulent Y. pestis suspended in beef bologna samples were 0.20 (+/- 0.01), 0.22 (+/- 0.01), 0.25 (+/- 0.02), 0.31 (+/- 0.01), 0.35 (+/- 0.01), and 0.37 (+/- 0.01) kGy at temperatures of 5, 0, -5, -10, -15, and -20 degrees C, respectively. When incorporated into a three-dimensional mesh, the predictive model followed a parabolic fit (R(2) = 0.84), where the log reduction = -0.264 - (0.039 x temp) - (3.833 x dose) - (0.0013 x temp(2)) - (0.728 x dose(2)). These results indicate that ionizing radiation would be an effective technology for control of Y. pestis in ready-to-eat fine emulsion sausage products.

Ionizing (gamma) radiation can effectively inactivate microorganisms and extend the shelf life of seafood. In this study, the ability of gamma irradiation to inactivate foodborne pathogens surface inoculated onto frozen seafood (scallops, lobster meat,. blue crab, swordfish, octopus, and squid) was investigated. The radiation D(10)-values (the radiation dose needed to inactivate 1 log unit of a microorganism) for Listeria monocyto genes, Staphylococcus aureus, and Salmonella inoculated onto seafood samples that were then frozen and irradiated in the frozen state (-20 degrees C) were 0.43 to 0.66, 0.48 to 0.71, and 0.47 to 0.70 kGy, respectively. In contrast, the radiation D(10)-value for the same pathogens suspended on frozen pork were 1.26, 0.98, and 1.18 kGy for L. monocytogenes, S. aureus, and Salmonella, respectively. The radiation dose needed to inactivate.these foodborne pathogens on frozen seafood is significantly lower than that for frozen meat or frozen vegetables.

TI Incidence of Fumonisin B-2 Production within Aspergillus Section Nigri Populations Isolated from California Raisins SO JOURNAL OF FOOD PROTECTION LA English DT Article ID OCHRATOXIN-A; WINE GRAPES; FUSARIUM-MONILIFORME; NATURAL OCCURRENCE; BLACK ASPERGILLI; NIGER; STRAINS; MYCOTOXINS; GENES; CORN AB Fungi belonging to Aspergillus section Nigri occur frequently and in high populations on grapes. Species within this section include Aspergillus niger, A. tubingensis, and A. carbonarius, and they are potential sources for mycotoxins including ochratoxin A and fumonisin B-2 (FB2) in grapes and grape products. Aspergillus section Nigri strains were isolated from California raisins to examine the frequency and extent of FB2 production. Of 392 strains isolated, 197 strains were identified as A. niger, 131 of which produced FB2. These strains produced from 1.2 to 27 mu g/ml FB2 in culture. PCR amplification of fum1 and fum19 gene fragments showed that all FB2-producing strains and nearly all nonproducing strains of A. niger contain these genes. An additional 175 strains were identified as A. tubingensis, none of which produced FB2. PCR with fund and fum19 primers amplified gene fragments of 14 and 25% of A. tubingensis strains, respectively, suggesting that putative orthologs of A. niger fumonisin biosynthetic genes might occur in A. tubingensis. These results indicate that FB2 production is common among field isolates of A. niger and suggest that the potential for FB2 contamination of California raisins should be addressed further.

SO JOURNAL OF HYDROLOGIC ENGINEERING LA English DT Article DE Urbanization; Impervious surface; Stormwater management; Soil erosion ID SEDIMENT TRANSPORT-EQUATION; SPATIAL VARIABILITY; EROSION PROCESSES; OVERLAND-FLOW; SCALE; INFILTRATION; SHEETWASH; PARAMETERS; SIMULATION; GRADIENT AB As a watershed is urbanized, characteristics of runoff from new upslope impervious surfaces may differ from runoff generated on the predevelopment soil surface in quantity, time of concentration, and sediment load. This may cause changes to the erosion regime on downslope soil surfaces. We simulated rainfall at three rates (20, 30, 40 mm/h) to generate runoff from 0: 6 m(2) boxes. Boxes were either treated with an impervious surface or filled with soil 0.2 m deep and were connected together in series of four boxes along the 4-m slope to produce different arrangements of impervious and pervious soil surfaces (0, 25, 50% impervious) and under different antecedent soil moisture conditions. Results indicate that previously established numerical models predicting runoff characteristics as a function of run-on characteristics generate good correlations at 0% imperviousness, but these correlations become insignificant as imperviousness increases. Imperviousness significantly influenced sediment regime, suggesting that some previously established equations relating soil erosion to run-on characteristics cannot be simply applied to areas where runoff production occurs on surfaces having an impervious component.

When surface-irrigation inflow is cut off, the calculated upstream flow depth goes to zero, because the discharge is zero. For short time steps, use of the kinematic-wave model can create an incorrect water-surface profile. Issues include difficulty in solving the continuity equation in the first upstream cell and a calculated adverse water-surface profile. The kinematic-wave model produces a recession time at the upstream boundary that is too small, that can lead to incorrect calculation of recession times when water continues to recede from the surface. This problem becomes more severe for smaller values of bottom slope. In this paper, we present a zero-inertia approximation to the water-surface profile at cutoff, which can be extended to the start of recession, after which calculations continue with the kinematic-wave model.

TI Male-Specific Sesquiterpenes from Phyllotreta Flea Beetles SO JOURNAL OF NATURAL PRODUCTS LA English DT Article ID AGGREGATION PHEROMONE; APHTHONA; HIMACHALENE; CRUCIFERAE; COLEOPTERA AB Flea beetles in several genera are known to possess male-specific sesquiterpenes, at least some of Which serve as aggregation, pheromones that attract both sexes. In continuing, research on the Chemical ecology of Phyllotreta flea beetles, six new male specific sesquiterpenes were identified, one from P. striolata (hydroxyketone 9) and five from P. pusilla (aldehydes 10-12 and 14 and alcohol 13),, both species are crop pests. The minute amounts from beetles provided mass. spectra, and chromatographic data but were insufficient for complete structure determination. However, it was discovered that the new compounds could all be produced by applying organic reactions to previously identified flea, beetle sesquiterpenes, and the resulting, larger amounts of material permitted, definitive. structure analysis by NMR. Molecular Modeling was used in conjunction with NMR to define relative configurations of several newly created stereogenic centers. The absolute configurations of natural 9-14 were established by chiral gas chromatography/. mass spectrometry. In electrophysiologicial tests (GC-EAD) conducted with P. striolata compound 9, was detected with high, sensitivity by) the beetle;antennae, which is consistent with a pheromonal function.,The research opens new possibilities. for using behavioral Chemicals to monitor or Manage these pest species.

Follow-up paired samples t tests showed a significant change in zBMI from baseline to 3 and 6 months for children in the overweight, obese, and severely obese weight categories. However, at 12 months only the overweight and obese students continued to show significant improvement from baseline in zBMI. Conclusions These findings suggest that an intensive behavioral weight loss intervention that has demonstrated efficacy for decreasing zBMI may have incrementally smaller effects for children as weight classification increases.

The Willapa Bay oyster reserves were set aside in 1890 to preserve stocks of the native oyster Ostrea lurida in this estuary, but these stocks were overfished and replaced with the introduced Pacific oyster Crassostrea gigas during the late 1920s. Pacific oysters have spawned and set naturally in this estuary on a fairly regular basis since that time, and have formed the basis of a sustainable fishery established on state oyster reserves. The fishery is managed as an annual sale of oysters to private aquaculture interests. Oysters are harvested mostly by hand from intertidal tracts, usually moved to better growing areas closer to the estuary mouth, and shell is required to be returned to the reserves to perpetuate the fishery. Although oyster harvest for human consumption will remain an important social management goal, these bivalves have been shown to provide a suite of other ecosystem functions and services. A survey of the reserves suggests that they represent 11.2% of the intertidal habitat in Willapa Bay and cover substantial subtidal areas as well. A comparison with historical maps suggests that most of the low intertidal area in the reserves formerly populated by native oysters is now covered primarily with eelgrass (Zostera marina), which potentially serves as important habitat for numerous other organisms, including juvenile salmon. Dungeness crab, and migratory waterfowl like black Brant. Native oysters can still potentially be restored to some of these areas, but the value of both introduced oysters and eelgrass as habitat and ecosystem engineers also deserves attention, and the reserves provide an excellent place to elucidate the role of these additional conservation targets at the landscape scale.

Alterations in primary carbon metabolism are likely to support the elevated demand for respiratory substrates, although the nature of these alterations is unknown. To gain insight into the metabolic changes that occur to provide substrates for wound-induced increases in respiration, changes in the concentrations of compounds that are substrates, intermediates or cofactors in the respiratory pathway were determined in sugarbeet (Beta vulgaris L) roots in the 4 days following injury. Both wounded and unwounded tissues of wounded roots were analyzed to provide information about localized and systemic changes that occur after wounding. In wounded tissue, respiration increased an average of 186%, fructose, glucose 6-phosphate, ADP and UDP concentrations increased, and fructose 1,6-bisphosphate, triose phosphate, citrate, isocitrate, succinate, ATP, UTP and NAD(+) concentrations decreased. In the non-wounded tissue of wounded roots, respiration rate increased an average of 21%, glucose 6-phosphate, fructose 6-phosphate, glucose 1-phosphate and ADP concentrations increased, and isocitrate, UTP, NAD(+), NADP(+), and NADPH concentrations declined. Changes in respiration rate and metabolite concentrations indicated that localized and systemic changes in primary carbon metabolism occurred in response to injury. In wounded tissue, metabolite concentration changes suggested that activities of the early glycolytic enzymes, fructokinase, phosphofructokinase, phosphoglucose isomerase, and phosphoglucomutase were limiting carbon flow through glycolysis. These restrictions in the respiratory pathway, however, were likely overcome by use of metabolic bypasses that allowed carbon compounds to enter the pathway at glycolytic and tricarboxylic acid (TCA) cycle downstream locations. In non-wounded tissue of wounded roots, metabolic concentration changes suggested that glycolysis and the TCA cycle were generally capable of supporting the small systemic elevation in respiration rate. Although the mechanism by which respiration is regulated in wounded sugarbeet roots is unknown, localized and systemic elevations in respiration were positively associated with one or more indicators of cellular redox status.

However, there is little or no information evaluating biochemical responses of dormant weed seeds to pathogens. Wild oat caryopses were incubated with four pathogenic fungal isolates to evaluate the response of the pathogen defense enzyme, polyphenol oxidase (PPO). Caryopsis PPO activity was induced by three Fusarium spp. isolates previously obtained from whole seeds incubated in the field whereas caryopsis PPO activity was decreased by a Pythium isolate. Fusarium avenaceum isolate F.a.1 caused the greatest PPO induction and was studied in more detail. When whole wild oat seeds were incubated on F.a.1, PPO activity was induced in seeds, hulls (lemma and palea), and caryopses. Incubation of whole seeds on F.a.1 gradually induced caryopsis PPO activity over an 8-d period, whereas incubation of caryopses on F.a.1 over a 4-d period caused a greater and more rapid induction of PPO activity. Very little PPO activity could be leached from untreated caryopses, but nearly all of the induced PPO activity in F.a.1-treated caryopses was readily leached when incubated in buffer. In Western blots, both untreated and F.a.1-treated leachates contained a similar to 57-kilodalton (kD) protein, putatively the mature and relatively inactive form of PPO. However, lower molecular weight antigenic proteins between similar to 52 and similar to 25 kD were strongly induced in F.a.1-treated caryopses, with this induction being correlated with the increase in PPO activity. We hypothesize that dormant weed seeds possess biochemical defenses against pathogens and, more specifically, that proteolysis in the presence of fungal pathogens may release an activated form of PPO from the surface of wild oat caryopses and hulls.

A greenhouse study (2006) and field studies (2007 to 2008) in Illinois and Nebraska were conducted to quantify the growth and interference of maize and velvetleaf in response to varying synthetic N fertilizer rates in soils with high and low N mineralization potential. Natural soils were classified as having "low mineralization potential" (LMP), while soils amended with composted manure were classified as having "high mineralization potential" (HMP). Maize and velvetleaf were grown in monoculture or in mixture in both LMP and HMP soils and fertilized with zero, medium, or full locally recommended N rate. In the greenhouse, velvetleaf interference in maize with respect to plant biomass increased as N rate increased in the HMP soil, whereas increasing N rate in the LMP soil reduced velvetleaf interference. In contrast, velvetleaf interference in maize decreased as N rate increased regardless of soil class in the field experiment. With respect to grain yield, velvetleaf interference in maize was unaffected by N rate or soil class. In both greenhouse and field experiments, velvetleaf biomass was greater in the HMP soil class, whereas maize interference in velvetleaf was generally greater in the LMP soil class. While soil N levels influenced weed-crop interference in the greenhouse, the results of the field study demonstrate the difficulty of controlling soil nutrient dynamics in the field and support a maize fertilization strategy independent of weed N use considerations.

This research was conducted to determine whether organic management systems with higher organic amendments and soil microbial biomass could reduce weed seed persistence compared with conventional management systems. Seeds of smooth pigweed and common lambsquarters were buried in mesh bags in organic and conventional systems of two long-term experiments, the Farming Systems Project at the Beltsville Agricultural Research Center, Maryland, and the Farming Systems Trial at the Rodale Institute, Pennsylvania. Seed viability was determined after retrieval at half-year intervals for 2 yr. Total soil microbial biomass, as measured by phospholipid fatty acid (PLFA) content, was higher in organic systems than in conventional systems at both locations. Over all systems, locations, and experiments, viable seed half-life was relatively consistent with a mean of 1.3 and 1.1 yr and a standard deviation of 0.5 and 0.3 for smooth pigweed and common lambsquarters, respectively. Differences between systems were small and relatively inconsistent. Half-life of smooth pigweed seeds was shorter in the organic than in the conventional system in two of four location-experiments. Half-life of common lambsquarters was shorter in the organic than in the conventional system in one of four location-experiments, but longer in the organic than in the conventional system in two of four location-experiments. There were few correlations between PLFA biomarkers and seed half-lives in three of four location-experiments; however, there were negative correlations up to -0.64-for common lambsquarters and -0.55 for smooth pigweed in the second Rodale experiment. The lack of consistent system effects on seed persistence and the lack of consistent associations between soil microbial biomass and weed seed persistence suggest that soil microorganisms do not have a dominating role in seed mortality. More precise research targeted to identifying specific microbial functions causing seed mortality will be needed to provide a clearer picture of the role of soil microbes in weed seed persistence.

In this research, we created a range of cover crop biomass and soybean densities to assess their weed-suppressive ability alone and in combination. The experiment was conducted in 2008 and 2009 in Maryland and Pennsylvania using five levels of cereal rye residue, representing 0, 0.5, 1.0, 1.5, and 2.0 times the ambient level, and five soybean densities ranging from 0 to 74 seeds m(-2). Weed biomass decreased with increasing rye residue and weeds were completely suppressed at levels above 1,500 g m(-2). Weed biomass also decreased with increasing soybean density in 2 of 4 site years. We evaluated weed suppression by fitting an exponential decay model of weed biomass as a function of rye biomass and a hyperbolic model of weed biomass as a function of soybean density at each of the five tactic levels. We multiplied these individual tactic models and included an interaction term to test for tactic interactions. In two of the four site-years, the combination of these tactics produced a synergistic interaction that resulted in greater weed suppression than would be predicted by the efficacy of each tactic alone. Our results indicate that increasing soybean planting rate can compensate for lower cereal rye biomass levels when these tactics are combined.

In greenhouse experiments, hexazinone, glyphosate, and imazapic were applied POST, and carbon dioxide (CO(2)) assimilation was measured with the use of an open-flow gas-exchange system up to 22 d after treatment (DAT). Carbon dioxide assimilation was reduced to zero, indicating plant death, for hexazinone- and glyphosate-treated napiergrass by 2 and 12 DAT, respectively. Imazapic-treated napiergrass CO(2) assimilation declined to a constant rate by 22 DAT, but never reached zero. Field studies at Chula and Ty Ty, Georgia, evaluated herbicides for napiergrass control. Herbicide treatments included autumn-only applications, autumn followed by spring applications, and spring-only applications. All autumn-applied treatments exhibited regrowth in the spring. Plants were not affected by cold winter temperatures. A spade tillage treatment was implemented in January 2010, but was not effective in controlling napiergrass. Spring treatments included split applications of autumn treatments and spring-only treatments of glyphosate, glyphosate plus sethoxydim, and imazapyr. Sequential autumn and spring treatments containing glyphosate at both locations failed to eradicate napiergrass. Imazapyr applied spring achieved 94% plant injury by 34 DAT, and indicated potential napiergrass control. Greenhouse results indicated multiple modes of action could be effective in reducing napiergrass growth, but were inconsistent with field results. Further field studies are needed to derive conclusive methods of napiergrass control. C1 [Cutts, George S., III; Grey, Timothy L.; Lee, R. Dewey; Tubbs, R.

Wide bed planting systems consist of planting multiple rows on a wide bed with 20 to 35% higher plant population than found in conventional ridged-row planting systems. The objective of this study was to evaluate the effect planting system has on yield response of 'Russet Norkotah' potato to irrigation and nitrogen. Planting systems evaluated were (1) conventional ridged-row with dammer-diking; (2) 3.7 m wide bed with five potato rows spaced 66 cm between adjacent rows centered on the bed and; (3) 3.7 m wide bed with seven potato rows spaced 46 cm between adjacent rows. Six irrigation amounts, 50, 70, 85, 100, 115, and 130%, of estimated evapotranspiration after tuber initiation and four nitrogen rates, < 20, 50, 100, and 150%, of conventional recommendations were applied to the three planting systems. Interactions between irrigation amounts and nitrogen rate were significant for total and U.S. No. 1 yield, irrigation water use efficiency, and gross return in one or both study years. Interactions between nitrogen rate and planting system were significant for total and U.S. No. 1 yield, irrigation water use efficiency and gross return in the first year of the study. Interactions between irrigation amount and planting system were not significant. In the first study year, total and U.S. No. 1 yields were significantly increased 12 and 19 percent, respectively, under the 7-row bed planting system compared to ridged-row planting system. Comparison of ridged-row planting system and 5-row bed planting system on 31 commercial potato fields in eastern Idaho representing a combined area of 2,800 ha over 5 years resulted in significantly higher total yield and irrigation water use efficiency with the bed planting system. The 5-row bed planting system averaged 6% higher total yield, 5% less water application and an 11% increase in irrigation water use efficiency. The results of this study demonstrate that under high intensity rate sprinkler irrigation in the soil and climatic conditions prevalent in eastern Idaho, bed planting systems provide viable production alternatives for irrigated potato production that may increase total yield, gross return, and irrigation water use efficiency.

Methods: The population included 1313 participants (aged 55-74 years) in the Carotenoids in Age-Related Eye Disease Study, an ancillary study of the Women's Health Initiative Observational Study. Scores on a modified 2005 Healthy Eating Index were assigned using responses to a food frequency questionnaire administered at baseline of the Women's Health Initiative Observational Study (1994-1998). Physical activity and lifetime smoking history were queried. An average of 6 years later, stereoscopic fundus photographs were taken to assess the presence and severity of AMD; it was present in 202 women, 94% of whom had early AMD, the primary outcome. Results: In multivariate models, women whose diets scored in the highest quintile compared with the lowest quintile on the modified 2005 Healthy Eating Index had 46% lower odds for early AMD. Women in the highest quintile compared with those in the lowest quintile for physical activity (in metabolic energy task hours per week) had 54% lower odds for early AMD. Although smoking was not independently associated with AMD on its own, having a combination of 3 healthy behaviors (healthy diet, physical activity, and not smoking) was associated with 71% lower odds for AMD compared with having high-risk scores (P < .001). Conclusion: Modifying lifestyles might reduce risk for early AMD as much as 3-fold, lowering the risk for advanced AMD in a person's lifetime and the social and economic costs of AMD to society.

We examined an abiotic phenol-polysaccharide matrix fabricated by the anodic grafting of catechol to chitosan films. Previous studies have shown. that catethol-modified chitosan films are redox-active and can be repeatedly interconverted between oxidized and reduced states. Here We developed quantitative electrochemical methods to characterize biorelevant redox properties of the catechol-modified chitosan films. Our analysis demonstrates that these films can (i) accept electrons from biological reductants ascorbate and nicotinamide adenine dinucleotide phosphate, NADPH) and (ii) donate electrons in a model biological oxidation process. Furthermore, these films can donate electrons to O-2 to generate H2O2. The demonstration that abiotic catechol-chitosan films possess catalytic in the absence of enzymes suggests the possibility that phenolic matrices may play an important role in redox cycling and reactive oxygen species (ROS) signaling in biology and the environment.

The plant contains the alkaloids swainsonine and calystegines, which inhibit cellular enzymes and cause systematic cell death. This study evaluated the behavioral effects on dams and kids of prenatal ingestion of this plant. Freshly harvested leaves of I. carnea (10 g/kg body weight) were fed daily to nine pregnant goats from the fifth to the 16th week of gestation; five pregnant goats were controls. Dam and kid behavior were evaluated during 2-hr postpartum. Further evaluation of the offspring was performed using various tests after birth: (1) reaching and discriminating their dam from an alien doe (two tests at 12-hr postpartum), and (2) navigating a progressive maze (2, 4, and 6 days postpartum). Postnatal (n=2) and fetal (n=2) mortality were observed in the treated group. Intoxicated kids had difficulty in standing at birth, and only one was able to suckle within 2 hr of birth. Treated kids were slower than controls to arrive at their dam in the discrimination test; treated kids often (seven of nine completed tests) incorrectly chose the alien dam (controls: 0/10 tests). During some runs on days 2, 4, and 6 postpartum, treated kids were slower to leave the starting point of the maze, and were slower to arrive at the dam on all test days. This study suggests that the offspring of pregnant goats given I. carnea during gestation have significant behavioral alterations and developmental delays.

During the 5-year study, 13 fawns were inoculated intracerebrally with CWD-infected brain material from white-tailed deer (n = 7; Group A) or elk (n = 6; Group B), and 3 other fawns were kept as uninoculated controls (Group C). As described previously, 3 CWD-inoculated deer were euthanized at 7.6 mo post-inoculation (MPI). None revealed presence of abnormal prion protein (PrPd) in their tissues. At 24 (Group A) and 26 (Group B) MPI, 2 deer were necropsied. Both animals had a small focal accumulation of PrPd in their midbrains. Between 29 and 37 MPI, 3 other deer (all from Group A) were euthanized. The 5 remaining deer became sick and were euthanized between 51 and 60 MPI (1 from Group A and 4 from Group B). Microscopic lesions of spongiform encephalopathy (SE) were observed in only these 5 animals; however, PrPd was detected in tissues of the central nervous system by immunohistochemistry, Western blot, and by commercial rapid test in all animals that survived beyond 24 MPI. This study demonstrates that intracerebrally inoculated fallow deer not only amplify CWD prions, but also develop lesions of spongiform encephalopathy.

TI Tumor Progression Locus 2 (TPL2) Regulates Obesity-Associated Inflammation and Insulin Resistance SO DIABETES LA English DT Article ID DIET-INDUCED OBESITY; INDUCED HEPATIC STEATOSIS; KAPPA-B-KINASE; ADIPOSE-TISSUE; IKK-BETA; ADIPOCYTE DEATH; ACTIVATION; MICE; MACROPHAGES; CELLS AB OBJECTIVE-Obesity-associated low-grade systemic inflammation resulting from increased adipose mass is strongly related to the development of insulin resistance and type 2 diabetes as well as other metabolic complications. Recent studies have demonstrated that the obese metabolic state can be improved by ablating certain inflammatory signaling pathways. Tumor progression locus 2 (TPL2), a kinase that integrates signals from Toll receptors, cytokine receptors, and inhibitor of kappa-B kinase-beta is an important regulator of inflammatory pathways. We used TPL2 knockout (KO) mice to investigate the role of TPL2 in mediating obesity-associated inflammation and insulin resistance. RESEARCH DESIGN AND METHODS-Male TPL2KO and wild-type (WT) littermates were fed a low-fat diet or a high-fat diet to investigate the effect of TPL2 deletion on obesity, inflammation, and insulin sensitivity. RESULTS-We demonstrate that TPL2 deletion does not alter body weight gain or adipose depot weight. However, hyper-insulinemic euglycemic clamp studies revealed improved insulin sensitivity with enhanced glucose uptake in skeletal muscle and increased suppression of hepatic glucose output in obese TPL2KO mice compared with obese WT mice. Consistent with an improved metabolic phenotype, immune cell infiltration and inflammation was attenuated in the adipose tissue of obese TPL2KO mice coincident with reduced hepatic inflammatory gene expression and lipid accumulation. CONCLUSIONS-Our results provide the first in vivo demonstration that TPL2 ablation attenuates obesity-associated metabolic dysfunction. These data suggest TPL2 is a novel target for improving the metabolic state associated with obesity.

Considering that rainfall erosivity is an important guide for planning soil erosion control practices, a spatial assessment of indices for characterizing the erosive force of rainfall in El Salvador Republic was carried out. Using pluviometric records from 25 weather stations, we applied two methods: erosivity index equation and the Fournier index. In all study area, the rainiest period is from May to November. Annual values of erosivity index ranged from 7,196 to 17,856 MJ mm ha(-1) h(-1) year(-1) and the Fournier index ranged from 52.9 to 110.0 mm. The erosivity map showed that the study area can be broadly divided into three major erosion risk zones, and the Fournier index map was divided into four zones. Both methods revealed that the erosive force is severe in all study area and presented significant spatial correlation with each other. The erosive force in the country is concentrated mainly from May to November. C1 [da Silva, Alexandre Marco] Univ Estadual Paulista, Dept Environm Engn, BR-18087180 Sao Paulo, Brazil.

TI Sampling coarse woody debris along spoked transects SO FORESTRY LA English DT Article ID LINE-INTERSECT; UNBIASED ESTIMATION AB Line transects are commonly used for sampling coarse woody debris (CWD). The USDA Forest Service Forest Inventory and Analysis programme uses a variant of this method that involves sampling for CWD along transects that radiate from the centre of a circular plot-like spokes on a wheel. A new approach for analysis of data collected with spoked transects is developed. This approach does not attempt to mimic traditional analysis methods for line transects, which do not readily apply to spoked transects. The method developed here generalizes to any number of spokes. We also demonstrate that there is a close relationship between spoked transects and a particular fixed plot design for sampling CWD.

The new sausage method performs best overall in terms of minimum variance criteria. This review should also help establish a description of the major fixed-area plot sampling methods that will allow unambiguous application and description in future studies.

We discuss approaches to immediately begin closing knowledge gaps, including: (1) harnessing collective expert knowledge so that data from professional experiences (e.g., personal collection and herbarium records) are better organized and made available to the broader mycological community; (2) thinking outside the mycology box by learning and borrowing from conservation approaches to other taxonomic groups; (3) developing and testing hypothesis-driven habitat models for representative fungi to provide support for habitat restoration and management; (4) framing ecological questions and conducting field surveys and research more directly pertinent to conservation information needs; and (5) providing adaptive management guidelines and strategies for resource managers to conserve fungi based on incrementally improving knowledge from experience and conservation research.

In this review we explore whether fungi that respond differently to N deposition also differ in functional traits, including organic N use, hydrophobicity and exploration type (extent and pattern of extraradical hyphae). Cortinarius, Tricholoma, Piloderma, and Suillus had the strongest evidence of consistent negative effects of N deposition. Cortinarius, Tricholoma and Piloderma display consistent protein use and produce medium-distance fringe exploration types with hydrophobic mycorrhizas and rhizomorphs. Genera that produce long-distance exploration types (mostly Boletales) and contact short-distance exploration types (e.g., Russulaceae, Thelephoraceae, some athelioid genera) vary in sensitivity to N deposition. Members of Bankeraceae have declined in Europe but their enzymatic activity and belowground occurrence are largely unknown. Bankeraceae produce a distinct hydrophobic mat exploration type that may also be important in N acquisition under conditions of low N availability.

TI Targeted Introgression of a Wheat Stem Rust Resistance Gene by DNA Marker-Assisted Chromosome Engineering SO GENETICS LA English DT Article ID F-SP TRITICI; FUSARIUM HEAD BLIGHT; PLANT LEAF RUST; DURUM-WHEAT; CYTOGENETIC CHARACTERIZATION; HOMOEOLOGOUS RECOMBINATION; MOLECULAR CHARACTERIZATION; CONFERRING RESISTANCE; TRANSLOCATION LINES; HEXAPLOID WHEAT AB Chromosome engineering is a useful strategy for transfer of alien genes from wild relatives into modern crops. However, this strategy has not been extensively used for alien gene introgression in most crops due to low efficiency of conventional cytogenetic techniques. Here, we report an improved scheme of chromosome engineering for efficient elimination of a large amount of goatgrass (Aegilops speltoides) chromatin surrounding Sr39, a gene that provides resistance to multiple stem rust races, including Ug99 (TTKSK) in wheat. The wheat ph1b mutation, which promotes meiotic pairing between homoeologous chromosomes, was employed to induce recombination between wheat chromosome 2B and goatgrass 2S chromatin using a backcross scheme favorable for inducing and detecting the homoeologous recombinants with small goatgrass chromosome segments. Forty recombinants with Sr39 with reduced surrounding goatgrass chromatin were quickly identified from 1048 backcross progenies through disease screening and molecular marker analysis. Four of the recombinants carrying Sr39 with a minimal amount of goatgrass chromatin (2.87-9.15% of the translocated chromosomes) were verified using genomic in situ hybridization. Approximately 97% of the goatgrass chromatin was eliminated in one of the recombinants, in which a tiny goatgrass chromosome segment containing Sr39 was retained in the wheat genome. Localization of the goatgrass chromatin in the recombinants led to rapid development of three molecular markers tightly linked to Sr39. The new wheat lines and markers provide useful resources for the ongoing global effort to combat Ug99. This study has demonstrated great potential of chromosome engineering in genome manipulation for plant improvement.

To gain insight into breeding progress over time, two advanced selections (UF1 and UF2) and 10 released cultivars, from Florida Belle (1975) to Florida Radiance (2008), were compared for various fruit quality traits in a two-location field study during the 2009-2010 season. Fruit size varied dramatically from 30.8 g for 'Elyana' to 16.2 g for 'Dover' at Balm, FL, and from 28.3 g for UF2 to 16.6 g for 'Dover' at Dover, FL. A linear regression of fruit size on year of release revealed an average gain of 2.6 g per year since 1975 for the cultivars and selections tested (R-2 = 0.44). A similar analysis revealed a reduction over time in the proportion of cull fruit (R-2 = 0.30). Gains were apparent for the redness of the internal flesh, from a colorimeter a* value of 16.1 for 'Florida Belle' (1975) to 34.7 for 'Carmine' (2002) but were not sustained for later releases and selections. Although there were significant differences among genotypes for all chemical traits affecting flavor, there were no discernable patterns over time. There were wide month-to-month variations in individual sugars and organic acids, except for citric acid, which was stable across months and locations. The ratio of soluble solids content to titratable acidity ranged widely among genotypes, from a high of 15.7 for 'Florida Belle' in February at Dover, FL, to a low of 6.4 for 'Winter Dawn' in January at Balm, FL. The observed variability and trends in fruit quality traits will help guide future genetic studies and inform decisions about future breeding priorities and selection procedures.

K. Koch] cultivars. The present study examines efficacy of aminoethoxyvinylglycine (AVG; formulated as ReTain (R); Valent BioSciences, Libertyville, IL), a natural ethylene inhibitor, for increasing nutmeat yield in a commercial 'Desirable' pecan orchard over a 2-year period. The 30-ha experiment consisted of two treatments (nontreated versus ReTain) in the first year, an "off" year in the orchard's alternate bearing cycle. The second year's study, an "on" year, consisted of four treatments (i.e., "08 nontreated + 09 nontreated," "08ReTain + 09 nontreated," "08 nontreated + 09 ReTain," and "08ReTain + 09 ReTain"). AVG, as ReTain [132 mg.L-1 a.i. (11.7 oz/acre)], was applied as two post-pollination canopy sprays (937 L.ha(-1)) 2 weeks apart in both years. During the "off" year, ReTain increased nut yield parameters with ReTain increasing kernel yield by 36% (704 kg.ha(-1) versus 516 kg.ha(-1)) over that of nontreated trees. In the subsequent "on" crop year, the trees exhibiting a ReTain-associated previous year yield increase of approximate to 36% exhibited a reduction in yield of approximate to 25%, thus largely negating the previous season's yield increase over a 2-year alternate bearing cycle. Additionally, ReTain-treated trees during the "on" year failed to exhibit an increase in yield parameters over that of the nontreated control. As a result of a lag effect on subsequent year yield parameters, ReTain offers potential as a crop-load management tool for 'Desirable' orchards in "off" years such as a year of relatively high nutmeat price followed by a year of relatively low price. There appears to be no positive effect on yield when used in a heavy crop-load "on" year of an alternate bearing cycle. Thus, ReTain might have benefit for stabilizing alternate bearing in 'Desirable' pecan orchards. Kernel quality (defined as percentage of nut weight as kernel) of individual nuts from "on" year trees was not as sensitive to units of yield increase as for individual nuts of "off" year trees, thus implying that the rate of assimilate partitioning to individual reproductive structures in "off"-year trees is not as great as that in "on"-year trees.

TI Grafting Technique to Eliminate Rootstock Suckering of Grafted Tomatoes SO HORTSCIENCE LA English DT Article DE meristems; axillary buds AB Vegetative grafting has been proposed as a technique for managing diseases in tomatoes under open-field conditions. Over 2 successive years, we investigated the use of grafting under open-field fresh tomato production and found a serious limitation with current grafting techniques, which resulted in recurring rootstock shoot regrowth ("suckering") from the rootstock cotyledons when left intact. Left unchecked, the regrowth of tomato rootstocks can envelop the experimental scions, which can impact the growth of field-grown tomatoes. In the Fall of 2007, the cultivars Multifort, Aloha, and TX-301 with 'FL-47' scions were grafted by a commercial propagator. These grafted plants were planted in a field experiment and after a time period, the number of rootstock suckers was counted and removed. This process was repeated over five time periods. In 2008, we grafted all of the plants below the rootstock cotyledons. During five different time periods spanning 57 d, bud regrowth from the rootstock occurred in all studied rootstocks in 2007. The difference in the 2 years was dramatic. In the first year, the number of plants with rootstock regrowth was as high as 84.6% in some of the plots for 'Multifort', 30.7% for 'Aloha', and 15.4% for 'TX-301'. In the second year, with a different grafting technique, no regrowth from the rootstocks was observed. Even when the rootstock regrowth was removed in 2007, the rootstock sprout growth would reappear from the rootstock. The statistical interaction of the percentage of plants with rootstock regrowth for all recorded dates in 2007 was significant for 'Multifort' (Tukey-Fischer P <= 0.05) but not 'Aloha' or 'TX-301'. Although the study also contained fumigation treatments, no interaction of soil treatments on root sprouting was observed. Since adopting this method, rootstock regrowth has not been observed in subsequent field experiments for the past 3 years. C1 USDA ARS, US Hort Res Lab, Ft Pierce, FL 34982 USA.

TI Growth and Ion Distribution Is Affected by Irrigation with Saline Water in Selected Landscape Species Grown in Two Consecutive Growing Seasons: Spring-summer and Fall-winter SO HORTSCIENCE LA English DT Article DE boxwood; escallonia; hawthorn; hibiscus; juniper; salt partitioning; visual quality ID SALT TOLERANCE; HERBACEOUS PERENNIALS; ACCUMULATION; POTASSIUM; RESOURCE; STRESS; SODIUM; PLANTS; CITRUS AB Landscape irrigation is the second largest user of reclaimed water in industrialized countries; however, its high concentration of soluble salts, especially Na+ and Cl-, may induce growth reduction and leaf necrosis or bronzing in ornamental species. The present study was conducted to determine the growth and quality responses and nutritional ion imbalances of selected landscape species during the container production phase when subjected to irrigation with water of increasing NaCl + CaCl2 concentrations. Plants of boxwood [Mucus microphylla var. japonica (Mull. Arg. ex Miq) Rehder & E.H. Wilson], escallonia (Escallonia xexoniensis hort. Veich ex Bean), hawthorn [Raphiolepis indica (L.) Lind. Ex Ker Gawl. x 'Montle'], hibiscus (Hibiscus rosa-sinensis L.), and juniper (Juniperus chinensis L.) were grown in a greenhouse in the Spring Summer and in the Fall Winter in separate experiments. Saline irrigation consisted of solutions with electrical conductivities (ECiw) of 0.6, 2, 4, 6, and 8 dS.m(-1) in the Spring Summer experiment and 0.6, 4, 6, 8, and 12 dS.m(-1) in the Fall Winter. Growth of the five species decreased when irrigated with saline waters. Leaf growth was highly sensitive to salinity and the average decrease in leaf dry weight was the criterion used to rank the tolerance of the species. In the Spring Summer experiment, the ranking was (higher tolerance to lower tolerance): juniper similar to boxwood > escallonia > hawthorn > hibiscus, whereas in Fall Winter, the ranking was: juniper boxwood > hibiscus > escallonia > hawthorn. The species were ranked according to their visual attractiveness in the Spring Summer experiment. The threshold ECiw at which visual attractiveness was affected gave the following ranking (higher to lower tolerance): hibiscus > juniper > escallonia > hawthorn > boxwood. Estimating the EC of drainage water from threshold ECiw, boxwood was classified as sensitive, hawthorn as moderately sensitive, escallonia as moderately tolerant, and hibiscus and juniper as highly tolerant. Tolerance of juniper was ascribed to Na+ and Cl- retention in the roots observed in both growing seasons and to the higher root biomass that allowed a higher accumulation of salts in this organ, preventing translocation to the leaves. Although boxwood exhibited acceptable tolerance in terms of growth, visual quality severely decreased; in contrast, growth of hibiscus was the most severely reduced but was rated as the most tolerant species in terms of visual quality. This opposite response may be the result of an excellent capacity to compartmentalize salts in hibiscus, whereas in boxwood, this mechanism may be absent.

TI Channel stability and sediment source assessment in streams draining a Piedmont watershed in Georgia, USA SO HYDROLOGICAL PROCESSES LA English DT Article DE channel stability; suspended sediment; stream channel erosion ID SOIL LOSS EQUATION; SUSPENDED SEDIMENT; RIVER BASINS; IDENTIFICATION; EVOLUTION; EROSION; LEGACY AB Streams can be classified as stable or unstable, depending on the stage of channel evolution. Many streams of the southern Piedmont in United States have high sediment loads and are listed as impaired under the total maximum daily load (TMDL) program and may be unstable. It is not clear as to what the target (reference) load or remediation measures should be for unstable streams. The objective of this study was to determine the relative channel stability for a typical southern Piedmont stream using rapid geomorphic assessments (RGAs) and sediment yield analysis. The results were supported through a sediment fingerprinting analysis. RGAs were performed along 52 reaches on the North Fork Broad River (NFBR) main stem and two tributaries. Annual sediment yields were calculated and compared with yields in the southern Piedmont for stable streams that are resilient to degradation or aggradation and unstable streams that are susceptible to such disturbances. Majority of the NFBR main stem was found to be unstable with signs of geomorphic instability in the form of degradation and aggradation. The estimated average annual sediment yield was 0.78 T ha(-1) year(-1). By comparison, the median annual yield is 0.20 T ha(-1) year(-1) for stable streams and 0.48 T ha(-1) year(-1) for unstable streams in the Piedmont ecoregion with comparable drainage basin size. We conclude that the NFBR is in an unstable stage of channel evolution. Sediment fingerprinting proved that majority of the stream-suspended sediment emanated from eroding stream channels. The methods outlined in this study have implications for the reference condition and remediation efforts related to stream turbidity and stream channel restoration.

TI Evaluation of a Sugar-Based Edible Adhesive Using a Tensile Strength Tester SO JALA LA English DT Article ID NATURAL-RUBBER; RESINS; MISCIBILITY; PLASTICS AB A method to evaluate adhesives has been developed and used to reformulate a recently patented adhesive which is based on sugar and citric acid. Factors affecting adhesive performance were uncovered, such as an optimal curing temperature of 60 degrees C. The addition of maltodextrin and soy protein at optimized levels was shown to nearly double the bonding strength of the adhesive, from 0.46 +/- 0.076 to 0.74 +/- 0.26 kN, under our test conditions. Also discussed is the potential for this method to be automated using commercially available equipment.

Effect of calorie restriction on the free-living physical activity levels of nonobese humans: results of three randomized trials. J Appl Physiol 110: 956-963, 2011. First published February 3, 2011; doi:10.1152/japplphysiol.00846.2009.-The objective of this study was to evaluate the influence of calorie restriction (CR) on free-living physical activity levels among humans. Data were from three CALERIE phase I site-specific protocols. Participants were nonobese (body mass index = 23.5-29.9 kg/m(2)) adults randomly assigned to 25% CR, low-calorie diet (LCD, 890 kcal/day supplement diet until 15% weight loss, then weight maintenance), or control at Pennington Biomedical Research Center (PBRC); 30% or 10% CR at Tufts University; and 20% CR or control at Washington University School of Medicine (WUSM). Activity was measured at months 0, 3, and 6 (PBRC) and at months 0, 3, 6, 9, and 12 (WUSM and Tufts). Total daily energy expenditure (TEE) by doubly labeled water and resting metabolic rate (RMR) were used to compute activity energy expenditure: AEE = TEE - RMR - 0.1 * TEE. Accelerometry and 7-day recall categorized activities by intensity. At Tufts, the 10% and 30% CR groups experienced significant decreases in AEE at months 6, 9, and 12. At month 6, a larger decrease in AEE was observed in the CR than the control group at WUSM. At months 3 and 6, larger decreases in AEE were observed in the CR and LCD groups than the control group at PBRC. Accelerometry and 7-day PAR did not consistently detect changes in activity categories. CR-associated changes in AEE were variable but, generally, reduced the energy deficit, which would reduce the expected rate of weight loss. Accelerometry and recall did not consistently explain reduced AEE, suggesting that increased muscle efficiency and/or decreased fidgeting accounted for decreased AEE. Inaccuracy of accelerometry and recall also likely negatively affected sensitivity. C1 [Martin, Corby K.; DeLany, James P.] Pennington Biomed Res Ctr, Baton Rouge, LA 70808 USA.

TI Anointing Chemicals and Hematophagous Arthropods: Responses by Ticks and Mosquitoes to Citrus (Rutaceae) Peel Exudates and Monoterpene Components SO JOURNAL OF CHEMICAL ECOLOGY LA English DT Article DE Citrus; Ectoparasites; Ticks; Mosquitoes; Monoterpenes; Anointing; Repellent ID FUR-RUBBING BEHAVIOR; ESSENTIAL OIL; IXODES-RICINUS; RHIPICEPHALUS-APPENDICULATUS; REPELLENT ACTIVITY; ATELES-GEOFFROYI; CAPUCHIN MONKEYS; CEBUS-CAPUCINUS; CULICIDAE; DIPTERA AB Some birds and mammals roll on or wipe themselves with the fruits or leaves of Citrus spp. or other Rutaceae. These anointing behaviors, as with anointing in general, are thought to function in the topical acquisition of chemicals that deter consumers, including hematophagous arthropods. We measured avoidance and other responses by nymphal lone star ticks (Amblyomma americanum) and adult female yellow fever mosquitoes (Aedes aegypti) to lemon peel exudate and to 24 volatile monoterpenes (racemates and isomers), including hydrocarbons, alcohols, aldehydes, acetates, ketones, and oxides, present in citrus fruits and leaves in order to examine their potential as arthropod deterrents. Ticks allowed to crawl up vertically suspended paper strips onto a chemically treated zone avoided the peel exudate and geraniol, citronellol, citral, carveol, geranyl acetate, alpha-terpineol, citronellyl acetate, and carvone. Ticks confined in chemically treated paper packets subsequently were impaired in climbing and other behaviors following exposure to the peel exudate and, of the compounds tested, most impaired to carveol. Mosquitoes confined in chambers with chemically treated feeding membranes landed and fed less, and flew more, when exposed to the peel exudate than to controls, and when exposed to aldehydes, oxides, or alcohols versus most hydrocarbons or controls. However, attraction by mosquitoes in an olfactometer was not inhibited by either lemon peel exudate or most of the compounds we tested. Our results support the notion that anointing by vertebrates with citrus-derived chemicals deters ticks. We suggest that some topically applied compounds are converted into more potent arthropod deterrents when oxidized on the integument of anointed animals.

In previous studies, we showed that cinnamyl alcohol, the most abundant blueberry floral volatile, and the green leaf volatiles (Z)-3-hexenyl acetate and hexyl acetate, emitted from both flowers and flower buds, elicit strong antennal responses from A. musculus. Here, we found that cinnamyl alcohol did not increase capture of A. musculus adults on yellow sticky traps compared with unbaited controls; however, weevils were highly attracted to traps baited with the Anthonomus eugenii Cano aggregation pheromone, indicating that these congeners share common pheromone components. To identify the A. musculus aggregation pheromone, headspace volatiles were collected from adults feeding on blueberry or cranberry flower buds and analyzed by gas chromatography-mass spectrometry. Three male-specific compounds were identified: (Z)-2-(3,3-dimethyl-cyclohexylidene) ethanol (Z grandlure II); (Z)-(3,3-dimethylcyclohexylidene) acetaldehyde (grandlure III); and (E)-(3,3- dimethylcyclohexylidene) acetaldehyde (grandlure IV). A fourth component, (E)-3,7-dimethyl-2,6-octadien-1-ol (geraniol), was emitted in similar quantities by males and females. The emission rates of these volatiles were about 2.8, 1.8, 1.3, and 0.9 ng/adult/d, respectively. Field experiments in highbush blueberry (New Jersey) and cranberry (Massachusetts) examined the attraction of A. musculus to traps baited with the male-produced compounds and geraniol presented alone and combined with (Z)-3-hexenyl acetate and hexyl acetate, and to traps baited with the pheromones of A. eugenii and A. grandis. In both states and crops, traps baited with the A. musculus male-produced compounds attracted the highest number of adults. Addition of the green leaf volatiles did not affect A. musculus attraction to its pheromone but skewed the sex ratio of the captured adults towards females. Although the role of plant volatiles in host-plant location by A. musculus is still unclear, our studies provide the first identification of the primary A. musculus aggregation pheromone components that can be used to monitor this pest in blueberry and cranberry pest management programs.

Efforts to identify its behavioral function have been complicated by contrasting reports that it either enhances or reduces attraction of flying beetles. Our studies failed to support the hypothesis that this published variability is due to differences in release rate and/or the enantiomeric composition [i.e., the beetle-produced (+)-enantiomer vs. the racemate] of the endo-brevicomin used in the experiments. In trapping trials within active D. frontalis infestations, racemic and (+)-endo-brevicomin did not differ from each other in behavioral effects when tested at seven different release rates ranging from 0.005 to 3 mg/d. At the highest release rates, racemic and (+)-endo-brevicomin similarly reduced catches in traps baited with an attractant (frontalin and turpentine), but neither enhanced catches at any release rate. Furthermore, the activity of racemic endo-brevicomin baits depended on trap proximity to D. frontalis infestations. Addition of these baits to attractant-baited traps located inside active infestations reduced catches, but they enhanced catches at traps located either 100 or 200 m outside these infestations. The contrasting responses may reflect differences in host-seeking strategies by either aggregated or dispersing D. frontalis, and may be elicited by differing abundance of natural sources of semiochemicals or differing responsiveness of beetles inside vs. outside of infestations. We suspect that much of the published variability in D. frontalis responses to endo-brevicomin is attributable to differing proximity of experimental field sites to infestations.

This study investigated contents of phenolics, flavonoids, and antioxidant activities in skin, pulp, and seeds of Miracle Fruit. The free phenolic content in skin was almost 3 times of that in pulp and 4 times of that in seeds. Skin contributed 43.96% of free phenolic compounds with 15.91% of freeze-dried solids due to its high phenolic content. As the trend observed for phenolic content, the free flavonoid content in the skin was tremendously higher than that in the seed and pulp. The skin contributed about 52% of total flavonoid with 15.91% of dried solids. On other hand, the differences in the bound phenolic contents were not so distinct among the 3 components. The free antioxidant activities in skin and pulp were comparable, and were significantly higher than that in seeds. Although the antioxidant activities in seeds was considerably lower than that in skin, 49.45% free antioxidant activity, 76.41% bound antioxidant activity, and 58.56% of total antioxidant activity were contributed by seeds due to about 66% of solid of total solids. In general, the results of antioxidant activities using sequential methods were higher than that using direct method. This study suggests that Miracle Fruit is a good source not only for flavor and color, and also antioxidant activity for functional food applications.

CFSP and CFISP contained 60.6% and 73.8% protein and 8.6% and 20.3% fat, respectively. Both CFSP and CFISP contained essential amino acids. Differences were observed between physicochemical properties of the 2 protein fractions, including nitrogen solubility, emulsion stability, and fat adsorption capacity. The flow and viscoelastic properties of the emulsions prepared with CFSP and CFISP were investigated using a rheometer. The power law model and the Casson model were used to determine the flow behavior index (n), consistency index (K), and yield stress. Emulsion containing CFSP (ECFSP) had a higher K value than emulsion containing CFISP (ECFISP). Both ECFSP and ECFISP emulsions exhibited pseudoplastic behavior and viscoelastic characteristics. The G' (an elastic or storage modulus) and G ' (a viscous or loss modulus) values for ECFSP were higher than ECFISP. Catfish muscle tissue can be easily separated into soluble and insoluble protein powders that have desirable functional properties.

TI Survival of Escherichia coli O157:H7 in Cucumber Fermentation Brines SO JOURNAL OF FOOD SCIENCE LA English DT Article DE cucumbers; E. coli O157:H7; fermentation brine; fermented vegetables; survival times ID LACTIC-ACID BACTERIA; CHLORINE TREATMENT; REDUCTION TIMES; O157-H7; GROWTH; PATHOGENS; MICROORGANISMS; VEGETABLES; VIABILITY; PRODUCTS AB Bacterial pathogens have been reported on fresh cucumbers and other vegetables used for commercial fermentation. The Food and Drug Administration currently has a 5-log reduction standard for E. coli O157:H7 and other vegetative pathogens in acidified pickle products. For fermented vegetables, which are acid foods, there is little data documenting the conditions needed to kill acid resistant pathogens. To address this knowledge gap, we obtained 10 different cucumber fermentation brines at different stages of fermentation from 5 domestic commercial plants. Cucumber brines were used to represent vegetable fermentations because cabbage and other vegetables may have inhibitory compounds that may affect survival. The 5-log reduction times for E. coli O157:H7 strains in the commercial brines were found to be positively correlated with brine pH, and ranged from 3 to 24 d for pH values of 3.2 to 4.6, respectively. In a laboratory cucumber juice medium that had been previously fermented with Lactobacillus plantarum or Leuconostoc mesenteroides (pH 3.9), a 5-log reduction was achieved within 1 to 16 d depending on pH, acid concentration, and temperature. During competitive growth at 30 degrees C in the presence of L. plantarum or L. mesenteroides in cucumber juice, E. coli O157:H7 cell numbers were reduced to below the level of detection within 2 to 3 d. These data may be used to aid manufacturers of fermented vegetable products determine safe production practices based on fermentation pH and temperature. Practical Application Disease causing strains of the bacterium E. coli may be present on fresh vegetables. Our investigation determined the time needed to kill E. coli in cucumber fermentation brines and how E. coli strains are killed in competition with naturally present lactic acid bacteria. Our results showed how brine pH and other brine conditions affected the killing of E. coli strains. These data can be used by producers of fermented vegetable products to help assure consumer safety.

TI Application of Polylactic Acid Coating with Antimicrobials in Reduction of Escherichia coli O157:H7 and Salmonella Stanley on Apples SO JOURNAL OF FOOD SCIENCE LA English DT Article DE antimicrobials; apple; coating; pathogens; PLA ID LISTERIA-MONOCYTOGENES; BACTERIAL PATHOGENS; O157-H7; SURVIVAL; CIDER; EFFICACY; GROWTH; FRUITS; NISIN; POSTHARVEST AB Survival of Escherichia coli O157:H7 and Salmonella Stanley on apples as affected by application of polylactic acid (PLA) coating with antimicrobials was investigated. Golden Delicious apples were spot inoculated with E. coli O157:H7 or S. Stanley and spray coated with PLA solutions containing lactic acid (LA), disodium ethylenediaminetetraacetic acid (EDTA), sodium benzoate (SB), potassium sorbate (PS), or their combination (LA + EDTA, SB + LA, SB + LA + EDTA). Apples without any coating treatment served as controls. Coating treatments were allowed to dry fully, and the apples were stored at 4 degrees C for 14 d. Antimicrobial coatings reduced populations of E. coli O157:H7 and S. Stanley by up to 4 log CFU/cm2 at 1 d and 4.7 log CFU/cm2 at 14 d, compared to controls. SB + LA combination had a similar effectiveness as the SB + LA + EDTA combination against both pathogens and was more effective than other coating treatments. Without antimicrobial treatment, E. coli O157:H7 and S. Stanley were able to survive on apples stored at 4 degrees C for up to 14 d. The antimicrobial PLA coating provides an alternative intervention to reduce the pathogens on apples. Practical Application Antimicrobial PLA coatings provide an alternative method to reduce pathogenic contaminations on fruit surface, and therefore, reduce the risk of food-borne outbreaks.

Many strains are now becoming multidrug resistant. Apple-based edible films containing carvacrol and cinnamaldehyde were evaluated for bactericidal activity against antibiotic resistant and susceptible C. jejuni strains on chicken. Retail chicken breast samples inoculated with D28a and H2a (resistant strains) and A24a (a sensitive strain) were wrapped in apple films containing cinnamaldehyde or carvacrol at 0.5%, 1.5%, and 3% concentrations, and then incubated at 4 or 23 degrees C for 72 h. Immediately after wrapping and at 72 h, samples were plated for enumeration of viable C. jejuni. The antimicrobial films exhibited dose- and temperature-dependent bactericidal activity against all strains. Films with >= 1.5% cinnamaldehyde reduced populations of all strains to below detection at 23 degrees C at 72 h. At 4 degrees C with cinnamaldehyde, reductions were variable for all strains, ranging from 0.2 to 2.5 logs and 1.8 to 6.0 logs at 1.5% and 3.0%, respectively. Films with 3% carvacrol reduced populations of A24a and H2a to below detection, and D28a by 2.4 logs at 23 degrees C and 72 h. A 0.5-log reduction was observed for both A24a and D28a, and 0.9 logs for H2a at 4 degrees C at 3% carvacrol. Reductions ranged from 1.1 to 1.9 logs and 0.4 to 1.2 logs with 1.5% and 0.5% carvacrol at 23 degrees C, respectively. The films with cinnamaldehyde were more effective than carvacrol films. Reductions at 23 degrees C were greater than those at 4 degrees C. Our results showed that antimicrobial apple films have the potential to reduce C. jejuni on chicken and therefore, the risk of campylobacteriosis. Possible mechanisms of antimicrobial effects are discussed. Practical Application Apple antimicrobial films could potentially be used in retail food packaging to reduce C. jejuni commonly present on food.

A reported chlorine stabilizer, T-128, has been developed to address this problem. In this study, we evaluated the ability of T-128 to stabilize free chlorine in wash solutions in the presence of high organic loads generated by the addition of lettuce extract or soil. Under conditions used in this study, T-128 significantly (P < 0.001) decreased the rate of free chlorine depletion at the presence of soil. T-128 also slightly decreased the rate of free chlorine depletion caused by the addition of lettuce extract in wash solution. Application of T-128 significantly reduced the survival of bacterial pathogens in wash solutions with high organic loads and significantly reduced the potential of cross-contamination, when contaminated and uncontaminated produce were washed together. However, T-128 did not enhance the efficacy of chlorinated wash solutions for microbial reduction on contaminated iceberg lettuce. Evaluation of several produce quality parameters, including overall visual appearance, package headspace O(2) and CO(2) composition, and lettuce electrolyte leakage, during 15 d of storage indicated that iceberg lettuce quality and shelf life were not negatively impacted by washing fresh-cut lettuce in chlorine solutions containing 0.1% T-128. Practical Application Reported chlorine stabilizer is shown to enhance chlorine efficacy against potential bacterial cross-contamination in the presence of high organic loads without compromising product quality and shelf life.

The model was validated using 2 (5 to 15 degrees C; 600 h and 10 to 40 degrees C; 52 h) sinusoidal, continuously varying temperature profiles. LWE adjusted to pH 7.8 was inoculated with approximately 2.5-3.0 log CFU/mL of Salmonella spp., and the growth data at several isothermal conditions (5, 7, 10, 15, 20, 25, 30, 35, 37, 39, 41, 43, 45, and 47 degrees C) was collected. A primary model (Baranyi model) was fitted for each temperature growth data and corresponding maximum growth rates were estimated. Pseudo-R2 values were greater than 0.97 for primary models. Modified Ratkowsky model was used to fit the secondary model. The pseudo-R2 and root mean square error were 0.99 and 0.06 log CFU/mL, respectively, for the secondary model. A dynamic model for the prediction of Salmonella spp. growth under varying temperature conditions was developed using 4th-order Runge-Kutta method. The developed dynamic model was validated for 2 sinusoidal temperature profiles, 5 to 15 degrees C (for 600 h) and 10 to 40 degrees C (for 52 h) with corresponding root mean squared error values of 0.28 and 0.23 log CFU/mL, respectively, between predicted and observed Salmonella spp. populations. The developed dynamic model can be used to predict the growth of Salmonella spp. in LWE under varying temperature conditions. Practical Application Liquid egg and egg products are widely used in food processing and in restaurant operations. These products can be contaminated with Salmonella spp. during breaking and other unit operations during processing. The raw, liquid egg products are stored under refrigeration prior to pasteurization. However, process deviations can occur such as refrigeration failure, leading to temperature fluctuations above the required temperatures as specified in the critical limits within hazard analysis and critical control point plans for the operations. The processors are required to evaluate the potential growth of Salmonella spp. in such products before the product can be used, or further processed. Dynamic predictive models are excellent tools for regulators as well as the processing plant personnel to evaluate the microbiological safety of the product under such conditions.

TI Use of Gelatin Gels as a Reference Material for Performance Evaluation of Meat Shear Force Measurements SO JOURNAL OF FOOD SCIENCE LA English DT Article DE gelatin gels; meat; reference material; shear force; texture ID BEEF TENDERNESS; STEAKS; TEXTURE; COOKING; MUSCLES; VALUES AB Establishing standards for meat tenderness based on Warner-Bratzler shear force (WBSF) is complicated by the lack of methods for certifying WBSF testing among texture systems or laboratories. The objective of this study was to determine the suitability of using gelatin gels as reference materials for performance testing of texture measurement systems. Three replications of 5 gels (15%, 20%, 25%, 30%, and 35% gelatin) were prepared, vacuum packaged, and stored at 4 degrees C until use. Three randomly selected strips from each gel were subjected to WBSF testing on 4 instruments (A, B, C, or D) on days 1 and 8. Additional strips from each gel were subjected to WBSF testing on instruments A and C on day 29. Regression line estimates for each set of gels were analyzed. Gel WBSF values ranged from 10 to 177 N. The WBSF by gel concentration response was highly linear (P < 0.0001) for all replications, instruments, and days of analysis. R2-values across all sets of gels ranged from 0.9562 to 0.9998. On days 1 and 8, instruments A and D exhibited higher slope (P < 0.0001) and lower intercept (P < 0.0001) estimates than instruments B and C. Regression line parameters (slope, intercept, and R2-values) were not influenced (P > 0.05) by length of gel storage (1, 8, and 29 d). Data from this study suggest that gelatin gels can be used for evaluating WBSF values from various instruments and for validating the performance of meat shear force testing. Practical Application Validating the performance of meat shear force testing is vital to establishing meat tenderness standards. The gelatin gel standards developed in this study exhibited a highly linear, repeatable relationship with shear force and were found to be stable for at least a month. These gel standards would provide a tool for the meat industry to harmonize shear force measurements across laboratories and various texture measuring instruments.

TI Custom-engineered chimeric foot-and-mouth disease vaccine elicits protective immune responses in pigs SO JOURNAL OF GENERAL VIROLOGY LA English DT Article ID FMD VACCINES; CELL-CULTURE; SAT TYPES; VIRUS; RECEPTOR; ACID; SEROTYPES; SEQUENCE; BINDING; DETERMINANTS AB Chimeric foot-and-mouth disease viruses (FMDV) of which the ant genic properties can be readily manipulated is a potentially powerful approach in the control of foot-and-mouth disease (FMD) in sub-Saharan Africa. FMD vaccine application is complicated by the extensive variability of the South African Territories (SAT) type viruses, which exist as distinct genetic and antigenic variants in different geographical regions. A cross-serotype chimeric virus, vKNP/SAT2, was engineered by replacing the external capsid-encoding region (1B-1D/2A) of an infectious cDNA clone of the SAT2 vaccine strain, ZIM/7/83, with that of SAT1 virus KNP/196/91. The vKNP/SAT2 virus exhibited comparable infection kinetics, virion stability and antigenic profiles to the KNP/196/91 parental virus, thus indicating that the functions provided by the capsid can be readily exchanged between serotypes. As these qualities are necessary for vaccine manufacturing, high titres of stable chimeric virus were obtained. Chemically inactivated vaccines, formulated as double-oil-in-water emulsions, were produced from intact 146S virion particles of both the chimeric and parental viruses. Inoculation of guinea pigs with the respective vaccines induced similar antibody responses. In order to show compliance with commercial vaccine requirements, the vaccines were evaluated in a full potency test. Pigs vaccinated with the chimeric vaccine produced neutralizing antibodies and showed protection against homologous FMDV challenge, albeit not to the same extent as for the vaccine prepared from the parental virus. These results provide support that chimeric vaccines containing the external capsid of field isolates can be successfully produced and that they induce protective immune responses in FMD host species.

TI Genetic and antigenic characterization of H1 influenza viruses from United States swine from 2008 SO JOURNAL OF GENERAL VIROLOGY LA English DT Article ID A H3N2 VIRUSES; RECEPTOR-BINDING; MOLECULAR-BASIS; HIGH VIRULENCE; NS1 PROTEIN; HOST; HEMAGGLUTININ; TRANSMISSION; PATHOGENESIS; EVOLUTION AB Prior to the introduction of the 2009 pandemic H1N1 virus from humans into pigs, four phylogenetic clusters (alpha-, beta-, gamma- and delta) of the haemagglutinin (HA) gene from H1 influenza viruses could be found in US swine. Information regarding the antigenic relatedness of the H1 viruses was lacking due to the dynamic and variable nature of swine lineage H1. We characterized 12 H1 isolates from 2008 by using 454 genome-sequencing technology and phylogenetic analysis of all eight gene segments and by serological cross-reactivity in the haemagglutination inhibition (HI) assay. Genetic diversity was demonstrated in all gene segments, but most notably in the HA gene. The gene segments from the 2009 pandemic H1N1 formed cluster; separate from North American swine lineage viruses, suggesting progenitors of the pandemic virus were not present in US pigs immediately prior to 2009. Serological cross-reactivity paired with antigenic cartography demonstrated that the viruses in the different phylogenetic clusters are also antigenically divergent.

TI Virulent Newcastle disease virus elicits a strong innate immune response in chickens SO JOURNAL OF GENERAL VIROLOGY LA English DT Article ID NITRIC-OXIDE; V-PROTEIN; PATHOGENESIS; INTERFERON; CELLS; GENES; PROLIFERATION; ACTIVATION; CALIFORNIA; INFECTION AB Newcastle disease virus (NDV) is an avian paramyxovirus that causes significant economic losses to the poultry industry worldwide. There is limited knowledge about the avian immune response to infection with virulent NDVs, and how this response may contribute to disease. In this study, pathogenesis and the transcriptional host response of chickens 10 a virulent NDV strain that rapidly causes 100% mortality was characterized. Using microarrays, a strong transcriptional host response was observed in spleens at early times after infection with the induction of groups of genes involved in innate antiviral and pro-inflammatory responses. There were multiple genes induced at 48 h post-infection including: type I and II interferons (IFNs), several cytokines and chemokines, IFN effectors and inducible nitric oxide synthase (iNOS). The increased transcription of nitric oxide synthase was confirmed by immunohistochemistry for iNOS in spleens and measured levels of nitric oxide in serum. In vitro experiments showed strong induction of the key host response genes, alpha IFN, beta interferon, and interleukin 1 beta and interleukin 6, in splenic leukocytes at 6 h post-infection in comparison to a non-virulent NDV. The robust host response to virulent NDV, in conjunction with severe pathological damage observed, is somewhat surprising considering that all NDV encode a gene, V, which functions as a suppressor of class I IFNs. Taken together, these results suggest that the host response itself may contribute to the pathogenesis of this highly virulent strain in chickens.

Aside from their importance in biomedicine, eicosanoids act in invertebrate biology. Prostaglandins (PGs) influence salt and water transport physiology in insect rectal epithelia and in Malpighian tubules. PGs also influence a few insect behaviors, including releasing oviposition behavior and behavioral fever. Eicosanoids act in ovarian development and in insect immunity. Because eicosanoids act in several areas of insect biology, we posed the hypothesis that chronic inhibition of eicosanoid biosynthesis, in the absence of microbial challenge, can influence insect life table parameters, including developmental time, survival, adult longevity and parasitoid fecundity. Here we report that inhibiting eicosanoid biosynthesis throughout the larval life exerted minor influences on some life table parameters of the greater wax moth, Galleria mellonella and its ectoparasitoid, Bracon hebetor, however, the inhibitors strongly reduced the production and hatchability of the parasitoids' eggs. The significance of the work relates to the potentials of understanding and targeting eicosanoid systems as a platform for developing new technologies of insect pest management. As seen here, the impact of targeting eicosanoid systems is seen in crucial moments of insect life histories, such as reproduction or immune challenge rather than in overall larval development.

Against a white background, T. castaneum adults were more likely to visit black pillars than white pillars when presented with a choice (e.g., 73% of beetles visited black and 17% visiting white pillar), and visits to black pillars increased with pillar height. When tested against a black background, beetles did not show a significant preference for either color pillar regardless of height. When comparing beetle's captures in pheromone/kairomone baited traps placed in front of a white or black panel in a white arena under high, low, or dark light conditions, more beetles were captured in traps in front of black panels under both high and low light conditions, but not under dark conditions. A similar pattern of capture under low light and dark conditions was also found for the closely related species T confusum. In a larger scale choice test, the same pattern of greater T. castaneum captures in traps in front of black panels than white panels was obtained, whether traps were placed in corners or along walls. Our results suggest that captures in monitoring traps could be increased by adding dark vertical shapes behind trap locations or placing traps near dark structures. Published by Elsevier Ltd.

The 1,269 amino acid porcine protein deduced from the nucleotide sequence shares 92% identity with the human IRS4 and possesses the same domains and the same number of tyrosine phosphorylation motifs as the human protein. We detected substitution FN424076:g.96C < G in the promoter region that segregates in Meishan and a synonymous substitution FN424076:g.1829T < C in the coding sequence with allele C present only in Meishan. Linkage mapping placed the IRS4 gene at position 82 cM on the current USDA-USMARC linkage map of porcine chromosome X. Association analyses were performed on 555 animals of 12th-15th generation of the Meishan x Large White cross and showed that both SNPs were highly significantly associated with backfat depth (P = 0.0005) and that the SNP FN424076:g1829T < C was also associated with loin depth (P = 0.017). The Meishan alleles increased back fat depth and decreased loin depth. IRS4 can be considered a positional candidate gene for at least some of the QTL located at the centromeric region of porcine chromosome X.

TI CROP ROTATION IMPACT ON SOIL QUALITY SO PAKISTAN JOURNAL OF BOTANY LA English DT Article ID MICROBIAL BIOMASS CARBON; ORGANIC-MATTER; INDICATORS; MANAGEMENT; FRACTIONS; ECOSYSTEM; DYNAMICS; SYSTEM; WHEAT AB Management systems influence soil quality over time. A study was carried out on Vanmeter farm of the Ohio State University South Centers at Piketon Ohio, USA to evaluate the impact of crop rotations on soil quality from 2002 to 2007. The crop rotations comprised of continuous corn (CC), corn-soybean (CS) and corn-soybean-wheat-cowpea (CSW). Ten soil cores were collected at 0-7.5, 7.5-15, 15-22.5 and 22.5-30 cm, and sieved. The soils were analyzed for total microbial biomass (C(mic)), basal respiration (BR) and specific maintenance respiration (qCO(2)) rates as biological quality indicators; total organic carbon (TC), active carbon (AC) and total nitrogen (TN) as chemical quality indicators; and aggregate stability (AS), particulate organic matter (POM) and total porosity (ft) as physical quality parameters at different depths of soil. The inductive additive approach based on the concept of "higher value of any soil property except ft, a better indicator of soil quality" was used to calculate the biological (SBQ), chemical (SCQ), physical (SPQ) and composite soil quality (SQI) indices. The results showed that crop rotation had significant impact on C(mic), BR, qCO(2), TC, AC, TN, AS and POM except ft at different depths of soil. The CSW had higher soil quality values than CC and CS. The values of selected soil quality properties under the given crop rotation significantly decreased except ft with increasing soil depth. The SBQ (23%), SCQ (16%), SPQ (7%) and SQI (15%) improved under CSW over time. The results imply that multiple cropping systems could be more effective for maintaining and enhancing soil quality than sole-cropping systems.

However, this approach has not been used extensively for the analysis of plant glycoproteins. As with all eukaryotes, N-glycosylation is a common post-translational modification for plant proteins traveling through the secretory pathway. Many such proteins are destined for the cell wall, or apoplast, where they play important roles in processes such as modifying cell wall structure, sugar metabolism, signaling, and defense against pathogens. Here, we describe a strategy to enrich for and identify secreted plant proteins based on affinity chromatography using the lectin Concanavalin A and two-dimensional liquid chromatography, together with matrix-assisted laser desorption/ionization MS analysis. The value of this approach is illustrated through the characterization of glycoproteins that are expressed in ripe tomato (Solanum lycopersicum) fruit, a developmental stage that is fundamentally linked with significant changes in cell wall structure and composition. This glycoprotein trap strategy allowed the isolation of a sub-proteome with an extremely high proportion of proteins that are predicted to be resident in the cell wall or secretory pathway, and the identification of new putative cell wall proteins.

Cows with subclinical hypocalcemia have no clinical signs of hypocalcemia but may be more susceptible to other diseases. The objective of this study was to determine the prevalence of subclinical hypocalcemia in the US dairy herds. As a part of the United States Department of Agriculture's National Animal Health Monitoring System 2002 Dairy study, serum samples were collected from 1462 cows within 48 h of parturition. The samples were sorted by lactation number: 1st (n = 454), 2nd (n = 447), 3rd (n = 291), 4th (n = 166), 5th (n = 72), and 6th (n = 32). Subclinical hypocalcemia (< 2.0 mM) increased with age and was present in 25%, 41%, 49%, 51%, 54%, and 42% of 1st-6th lactation cows, respectively. Cows with serum calcium concentrations > 2.0 mM had significantly lower serum non-esterified fatty acids indicating better energy balance than those with subclinical hypocalcemia. Subclinical hypocalcemia may make cows more susceptible to secondary diseases but more research will be required to determine if this is true. Published by Elsevier Ltd.

The pH, Ca2+, Mg2+, NH (4) (+) , acid neutralizing capacity, and electrical conductivity of wetland porewater and streamwater were higher in the basins with mixed geology. Bryophyte cover was higher in lower pH, crystalline basins, and vascular plant cover was higher in the mixed bedrock basins. On average, wetland porewater had lower pH and higher concentrations of dissolved organic carbon (DOC) and nitrogen and several other ions than streamwater; however, because discharge from these small wetlands is low, their direct influence on stream solute concentrations was generally undetectable. Dilution altered stream solute concentrations during peak flow in both basin types, but had little effect on wetland chemistry. In contrast to other solutes, the concentration of DOC in streams increased marginally during peak runoff and its concentration in wetland porewater was stable throughout the year. These findings further knowledge of the influence of watershed characteristics on wetland and stream chemistry and will inform future decisions regarding conservation and management in headwater basins.

Turnbull Lower-Bound median willingness to pay (willingness to accept compensation) was estimated at $3,547 ($5,313) per household for the short-run program and $2,765 ($5,101) per household for the long-run program.

The instrument was linked to a differential global positioning system via a hand-held field computer to geo-reference data. Apparent conductivity was converted to salinity using a regression derived from field data, and mapped to illustrate spatial salinity gradients throughout the marshes. Plant communities occurring at the study sites included native low marsh, high marsh, and brackish tidal riverbank marsh, as well as communities dominated by native and non-native common reed, Phragmites australis. Results revealed mean salinity values were significantly different between each of the community categories sampled within the Estuary. Due to management concerns over expansion of Phragmites within the Estuary, we mapped the salinity range for this community and provided graphic and numerical estimates of potential Phragmites habitat based on salinity alone (26% of the total acreage surveyed). Electromagnetic induction is an efficient tool for rapid reconnaissance of apparent conductivity and salinity gradients in tidal marsh soils that can be superimposed on aerial imagery to estimate suitable habitat for restoration or invasive control based on salinity ranges.

This is significant as mangroves are subject to rapid rates of deforestation and therefore could be significant sources of atmospheric emissions. Mangroves could be key ecosystems in strategies addressing the mitigation of climate change though reduced deforestation. We quantified ecosystem C stocks at the seaward, interior, and upland edges of mangroves in the Republic of Palau and Yap, Federated States of Micronesia. The relatively high aboveground biomass coupled with carbon-rich soils resulted in the presence of large ecosystem carbon stocks compared to other tropical forests. Ecosystem C storage at the Palau site ranged from 479 Mg/ha in the seaward zone to 1,068 Mg/ha in the landward zone; in the Yap site C storage ranged from 853 to 1,385 Mg/ha along this gradient. Soils contained similar to 70% of the ecosystem C stocks. The elevation range of mangroves was < 146 cm, suggesting that projected sea-level rise can influence a large portion of existing stands. Declines in ecosystem carbon stocks will be pronounced if mangroves are replaced by communities adapted to greater inundation such as seagrass communities, where C pools were a parts per thousand currency sign7% of that of mangroves (48 Mg C/ha).

TI Breeding Biology of the Threadstalk Milkvetch, Astragalus filipes (Fabaceae), with a Review of the Genus SO AMERICAN MIDLAND NATURALIST LA English DT Article ID POLLINATION ECOLOGY; BASALT MILKVETCH; SEED PRODUCTION; PLANT; POLLEN; RESTORATION; DISPERSAL; PREDATION; SUCCESS; SYSTEMS AB Astragalus L. (Fabaceae) is an enormous and diverse plant genus with a cosmopolitan distribution, but relatively few breeding biologies are known for its member species. Threadstalk (or basalt) milkvetch, Astragalus pipes Torrey ex. A. Gray, is common and widespread throughout the U.S. Intermountain West, including the Great Basin. It is being studied and ultimately propagated for extensive rangeland restoration projects throughout the sagebrush steppe. Understanding the breeding biology of A. filipes will be necessary for reliable and consistent commercial seed production with this species. We examined reproductive output from four manual, pollination treatments (autogamy, geitonogamy, xenogamy and distant xenogamy) in a common garden. As measures of fitness, we counted fruit and seed set, then germinated viable seeds, to assess reproductive output. This species is weakly self compatible; xenogamous pollen transfer results in nine times more seed per pollination. Pollen transfer between geographically distant seed accessions resulted in a decrease in seed germination, but no difference in fruit or seed set. Cross pollination by bees will be necessary for copious seed production by this species. In the wild, flowers of A. filipes are visited most commonly and ubiquitously by a diversity of Osmia bee species plus several bee species each of Eucera, Anthidium, Bombus and sometimes Hoplitis.

TI Short-term Effects of Burning and Disking on Songbird Use of Floodplain Conservation Easements SO AMERICAN MIDLAND NATURALIST LA English DT Article ID DICKCISSEL SPIZA-AMERICANA; TALLGRASS PRAIRIE; RIPARIAN HABITATS; BIRD COMMUNITIES; ABUNDANCE; FIRE; IOWA; ARTHROPODS; NORTHWEST; PARTNERS AB Extensive conversion of Midwestern riparian areas for agricultural production has had many consequences including reduced habitat for nesting birds. However, more than 120,000 ha of riparian habitat have been restored in this region through USDA conservation programs. In 2001 and 2002, we assessed songbird responses to burning and disking for management of conservation easements in east-central Iowa. We randomly assigned herbaceous riparian fields to burning and disking treatments and collected data on density and species richness of songbirds in these habitats. Total density of grassland and wetland species and red-winged blackbirds (Agelaius phoeniceus) were reduced by burning in the first and second breeding seasons after burning; common yellowthroat (Geothlypis trichas) density decreased with burning only in the first season. Disking led to increased density of grassland and wetland birds and greater overall avian conservation value on treated relative to untreated fields in the year after treatment. Changes associated with burning and disking treatments were likely related to changes in both vegetation structure and abundance of arthropod food resources. Despite decreased bird densities with burning, fire is a necessary management tool to control woody vegetation. Overall, both burning and disking appear to be effective management practices for maintaining herbaceous riparian habitats for grassland birds.

TI Ruffed Grouse Selection of Drumming Sites in the Black Hills National Forest SO AMERICAN MIDLAND NATURALIST LA English DT Article ID RESOURCE SELECTION AB Ruffed grouse (Bonasa umbellus) are important game birds that, depend on multiple forest age-classes of aspen (Populus spp.) for food and cover, which makes them an appropriate management indicator species for the condition of quaking aspen (Populus tremuloides) communities in the Black Hills National Forest of western South Dakota and northeastern Wyoming (BHNF). Recent landscape-scale drumming surveys showed that occupancy of ruffed grouse in the BHNF depended primarily on the amount of aspen-dominated vegetation within a 95 ha site. However, an investigation of drumming site characteristics is lacking. To evaluate drumming site selection, we located and measured the drumming structure and surrounding vegetation for 49 primary drumming sites and 147 paired unused sites during 2007 and 2008. We used discrete-choice modeling with an information-theoretic approach to evaluate resource characteristics of drumming sites associated with use. Percent area exposed (visibility) between 0.9 in and 1.8 m in height around the drumming structure had a negative, exponential relationship with drumming site selection and the combined density of woody and herbaceous plants >= 1-m tall with a stem diameter < 2.54 cm had a positive, asymptotic relationship with site selection. Reducing the visibility between 0.9 m and 1.8 m around the structure from 40% to 0% increased the relative probability of selection of drumming sites 9-fold. Increasing the density of woody and herbaceous stems from 8000 stems/hectare to 24,000 stems/hectare increased the relative probability of selection 20-fold. The selection of drumming sites with a high density of vegetation >= 1 m in height and low visibility between 0.9 m and 1.8 m suggests ruffed grouse select drumming sites that might reduce the chances of predation. Thus, management actions to improve ruffed grouse breeding habitat should focus on increasing the density of vegetation cover >= 1 m in height.

TI Amphibole asbestos soil contamination in the USA: A matter of definition SO AMERICAN MINERALOGIST LA English DT Article DE Asbestos; soils; amphiboles; asbestiform ID MESOTHELIOMA; MONTANA; LIBBY AB Recent concerns surrounding asbestos exposure have extended from occupational settings into natural settings. These developments have caused us to examine the distribution of amphiboles, which are potential asbestiform minerals, within the soils of the U.S.A. Evaluation of mineralogical data from selected sand and/or silt fraction of soils from the USDA-NRCS National Cooperative Soil Survey database shows that soils in all states (except for Rhode Island) contain amphiboles. In 41 of the 50 states, 10% or more sampled pedons contain amphiboles. Overall, 4396 pedons out of the 34326 pedons (about 13%) sampled in the U.S.A. contained amphiboles. Pedons containing amphiboles ranged from less than 1 to 49% of the pedons among all states. While amphibole asbestos deposits occur in mafic and ultramafic provinces, soil amphiboles occur evenly distributed across the U.S.A. The majority of the amphiboles found in the soils would likely not meet the mineralogical definition of asbestos (i.e., they would not have been derived from asbestiform amphiboles); however, the majority would likely meet a commonly used regulatory definition of a fiber (i.e., are over 5 mu m in length with a greater than 3 to 1 aspect ratio). Based on the regulatory definition, 13% of soil pedons and 5% of soil horizons in the U.S.A. are "naturally contaminated."

We present a list of the top 40 high-priority, multidisciplinary research questions directed toward informing some of the most important current and future decisions about management of species, communities, and ecological processes in the United States. The questions were generated by an open, inclusive process that included personal interviews With decisionmakers, broad solicitation of research needs from scientists and policymakers, and an intensive workshop that included scientifically oriented individuals responsible for managing and developing policy related to natural resources. The process differed from previous efforts to set priorities for conservation research in its focus on the engagement of decisionmakers in addition to researchers. The research priorities emphasized the importance of addressing societal context and exploration of trade-offs among alternative policies and actions, as well as more traditional questions related to ecological processes and functions.

Upon optimization using an implicit salvation method, COSMO, the syn or observed form was still not predicted to be of lower energy than the phi(H)-anti form, even though optimization after addition of several explicit water molecules did show a relative energy difference favoring the syn form. In order to examine the predictive ability of COSMO on this carbohydrate, constant energy dynamics, DFTMD, simulations were carried out on low energy syn and phi(H)-anti conformations with and without COSMO included during the dynamics. The resulting analysis confirmed that when COSMO is included in the dynamics, the syn conformations become energetically favored over the phi(H)-anti forms suggesting that both solvent and entropy play roles in dictating the solution conformation of cellobiose. Analysis of the dynamic runs includes distributions of selected dihedral angles versus time, conformational transitions, and populations of some quasi-planar, boat, skew forms during the simulations.

TI A Leptospira borgpetersenii Serovar Hardjo Vaccine Induces a Th1 Response, Activates NK Cells, and Reduces Renal Colonization SO CLINICAL AND VACCINE IMMUNOLOGY LA English DT Article ID NATURAL-KILLER-CELLS; WC1(+) GAMMA-DELTA; TYPE-1 IMMUNE-RESPONSE; BOVIS INFECTION; T-CELLS; ADAPTIVE IMMUNITY; CATTLE; CHALLENGE; GROWTH; CD4 AB Chronic infection of cattle with Leptospira borgpetersenii serovar Hardjo reduces animal production through reproductive failure and presents a persistent health threat to workers in the animal industry. Cattle are maintenance hosts for serovar Hardjo, and development of vaccines that establish long-term protective immunity has been problematic; induction of high titers of anti-serovar Hardjo antibody does not appear to be protective. Rather, development of an antigen-specific Th1 response appears to be critical for limiting renal colonization and urinary shedding of bacteria. In this study we compared two monovalent killed bacterial cell vaccines to assess long-term (12 months) protection against live serovar Hardjo challenge. Although neither vaccine prevented infection, renal colonization and urinary shedding of bacteria were reduced compared to those of control animals. Increased proliferation of CD4(+), CD8(+), and gamma delta T cells from vaccinated, but not control, animals was detected. In addition, NK cells from vaccinated animals and from all animals following infection, when exposed to antigen ex vivo, demonstrated a gamma interferon (IFN-gamma) recall response. We propose that programming NK cells to respond quickly to L. borgpetersenii serovar Hardjo infection may be an important step toward developing protective immunity.

Interest in this enzyme class continues due to their ability to macerate tissues of economically important crops and their use in a number of industrial processes. Rhizopus oryzae has a large PG gene family with 15 of 18 genes encoding unique active enzymes. The PG enzymes, 12 endo-PG and 3 exo-galacturonases, were expressed in Pichia pastoris and purified enabling biochemical characterization to gain insight into the maintenance of this large gene family within the Rhizopus genome. The 15 PG enzymes have a pH optima ranging from 4.0 to 5.0. Temperature optima of the 15 PG enzymes vary from 30 to 40 degrees C. While the pH and temperature optima do little to separate the enzymes, the specific activity of the enzymes is highly variable ranging from over 200 to less than 1 mu mol/min/mg. A general pattern related to the groupings found in the phylogentic tree was visible with the group containing the exo-PG enzymes demonstrating the lowest specific activity. Finally, the progress curves of the PG enzymes, contained within the phylogenetic group that includes the exo-PG enzymes, acting on trigalacturonic acid lend additional support to the idea that the ancestral form of PG in Rhizopus is endolytic and exolytic function evolved later.

TI Protection From Retinopathy and Other Complications in Patients With Type 1 Diabetes of Extreme Duration The Joslin 50-Year Medalist Study SO DIABETES CARE LA English DT Article ID ADVANCED GLYCATION ENDPRODUCTS; MICROVASCULAR COMPLICATIONS; PREVALENCE; ASSOCIATION; PROGRESSION; DIAGNOSIS; MELLITUS; DISEASE; UKPDS; RISK AB OBJECTIVE-To assess complication prevalence and identify protective factors in patients with diabetes duration of >= 50 years. Characterization of a complication-free subgroup in this cohort would suggest that some individuals are protected from diabetes complications and allow identification of endogenous protective factors. RESEARCH DESIGN AND METHODS-Cross-sectional, observational study of 351 U.S. residents who have survived with type 1 diabetes for >= 50 years (Medalists). Retinopathy, nephropathy, neuropathy, and cardiovascular disease were assessed in relation to HbA(1c), lipids, and advanced glycation end products (AGEs). Retrospective chart review provided longitudinal ophthalmic data for a subgroup. RESULTS-A high proportion of Medalists remain free from proliferative diabetic retinopathy (PDR) (42.6%), nephropathy (86.9%), neuropathy (39.4%), or cardiovascular disease (51.5%). Current and longitudinal (the past 15 years) glycemic control were unrelated to complications. Subjects with high plasma carboxyethyl-lysine and pentosidine were 7.2-fold more likely to have any complication. Of Medalists without PDR, 96% with no retinopathy progression over the first 17 years of follow-up did not experience retinopathy worsening thereafter. CONCLUSIONS-The Medalist population is likely enriched for protective factors against complications. These factors might prove useful to the general population with diabetes if they can be used to induce protection against long-term complications. Specific AGE combinations were strongly associated with complications, indicating a link between AGE formation or processing with development of diabetic vasculopathy.

Environmental conditions that are experienced in early life can profoundly influence human biology and long-term health. Developmental origins of health and disease and life-history transitions are purported to use placental, nutritional, and endocrine cues for setting long-term biological, mental, and behavioral strategies in response to local ecological and/or social conditions. The window of developmental plasticity extends from preconception to early childhood and involves epigenetic responses to environmental changes, which exert their effects during life-history phase transitions. These epigenetic responses influence development, cell-and tissue-specific gene expression, and sexual dimorphism, and, in exceptional cases, could be transmitted transgenerationally. Translational epigenetic research in child health is areiterative process that ranges from research in the basic sciences, preclinical research, and pediatric clinical research. Identifying the epigenetic consequences of fetal programming creates potential applications in clinical practice: the development of epigenetic biomarkers for early diagnosis of disease, the ability to identify susceptible individuals at risk for adult diseases, and the development of novel preventive and curative measures that are based on diet and/or novel epigenetic drugs.

TI Multidimensional NMR analysis reveals truncated lignin structures in wood decayed by the brown rot basidiomycete Postia placenta SO ENVIRONMENTAL MICROBIOLOGY LA English DT Article ID SOLUTION-STATE NMR; PLANT-CELL WALLS; FUNGUS; DEGRADATION; CLEAVAGE; BIODEGRADATION; MECHANISM; OXIDATION; CELLULOSE; SPRUCE AB P>Lignocellulose biodegradation, an essential step in terrestrial carbon cycling, generally involves removal of the recalcitrant lignin barrier that otherwise prevents infiltration by microbial polysaccharide hydrolases. However, fungi that cause brown rot of wood, a major route for biomass recycling in coniferous forests, utilize wood polysaccharides efficiently while removing little of the lignin. The mechanism by which these basidiomycetes breach the lignin remains unclear. We used recently developed methods for solubilization and multidimensional 1H-13C solution-state NMR spectroscopy of ball-milled lignocellulose to analyse aspen wood degraded by Postia placenta. The results showed that decay decreased the content of the principal arylglycerol-beta-aryl ether interunit linkage in the lignin by more than half, while increasing the frequency of several truncated lignin structures roughly fourfold over the level found in sound aspen. These new end-groups, consisting of benzaldehydes, benzoic acids and phenylglycerols, accounted for 6-7% of all original lignin subunits. Our results provide evidence that brown rot by P. placenta results in significant ligninolysis, which might enable infiltration of the wood by polysaccharide hydrolases even though the partially degraded lignin remains in situ. Recent work has revealed that the P. placenta genome encodes no ligninolytic peroxidases, but has also shown that this fungus produces an extracellular Fenton system. It is accordingly likely that P. placenta employs electrophilic reactive oxygen species such as hydroxyl radicals to disrupt lignin in wood.

TI Persistence of Resistance Plasmids Carried by Beta-Hemolytic Escherichia coli When Maintained in a Continuous-Flow Fermentation System Without Antimicrobial Selection Pressure SO FOODBORNE PATHOGENS AND DISEASE LA English DT Article ID ANTIBIOTIC-RESISTANCE; CHLORAMPHENICOL RESISTANCE; DRUG RESISTANCE; NEONATAL SWINE; COST; DIARRHEA; FITNESS AB It is thought that antimicrobial resistance imposes a fitness cost on bacteria, so that a reduction in antimicrobial use may reduce the incidence of resistant bacteria. The objectives of the present study were to determine (1) whether multidrug resistant (MDR) Escherichia coli field strains with different plasmid profiles show disparate plasmid loss when grown over time without selection pressure; (2) whether the number of plasmids present in the cell affects growth. Nine beta-hemolytic E. coli strains from swine (n = 8) and cattle (n = 1) were grown in separate continuous-flow vessels for 36 days without antimicrobial selection. Populations were enumerated on brain heart infusion agar and brain heart infusion agar with tetracycline on days 2, 5, 8, 15, 22, 29, and 36. Growth rates, plasmid profiles and susceptibility profiles of the strains were compared, and day 36 isolates (n = 40, five for each MDR strain) were compared with their corresponding day 0 strains. Plasmid content of the nine field strains ranged from zero to eight with sizes from 3.2 to 165 kb. Changes in susceptibility profiles of day 36 isolates were observed among 20% (8 of 40) of the isolates. MDR E. coli largely maintained their original plasmid profiles, replicon types, and susceptibility profiles over 36 days of continuous culture. There was no significant difference in maximum specific growth rate among strains when compared with the plasmid-free strain or when day 36 isolates were compared with their own day 0 strain. This suggests that there is little fitness cost in the maintenance of multiple plasmids of various sizes under the conditions of this study. Other strategies rather than merely reducing antimicrobial usage are needed to combat the emergence of MDR bacteria.

When inoculated at 1 log CFU/mL, E. coli O157:H7 attachment to blades after 24 and 48 h incubation at dynamic temperature (6.09 and 6.37 log CFU/mL) was significantly higher than when incubated at 22 degrees C (4.84 and 5.68 log CFU/mL), respectively. After 48 h incubation, two blades were sprayed on each side with a cocktail of E. coli O157-specific bacteriophages before scraping the blade, and subsequent plating on Sorbitol MacConkey media-nalidixic acid. Application of bacteriophages reduced E. coli O157:H7 populations by 4.5 log CFU on blades after 2 h of phage treatment. Our study demonstrates that E. coli O157:H7 can attach to and proliferate on spinach harvester blades under static and dynamic temperature conditions, and bacteriophages are able to reduce E. coli O157:H7 populations adhered to blades.

TI Utility of a Panviral Microarray for Detection of Swine Respiratory Viruses in Clinical Samples SO JOURNAL OF CLINICAL MICROBIOLOGY LA English DT Article ID TRANSMISSIBLE GASTROENTERITIS VIRUS; HETEROCLITE SUBGENOMIC RNAS; TIME RT-PCR; INFLUENZA-VIRUS; UNITED-STATES; CORONAVIRUS; PIGS; INFECTION; EMERGENCE; DISEASE AB Several factors have recently converged, elevating the need for highly parallel diagnostic platforms that have the ability to detect many known, novel, and emerging pathogenic agents simultaneously. Panviral DNA microarrays represent the most robust approach for massively parallel viral surveillance and detection. The Virochip is a panviral DNA microarray that is capable of detecting all known viruses, as well as novel viruses related to known viral families, in a single assay and has been used to successfully identify known and novel viral agents in clinical human specimens. However, the usefulness and the sensitivity of the Virochip platform have not been tested on a set of clinical veterinary specimens with the high degree of genetic variance that is frequently observed with swine virus field isolates. In this report, we investigate the utility and sensitivity of the Virochip to positively detect swine viruses in both cell culture-derived samples and clinical swine samples. The Virochip successfully detected porcine reproductive and respiratory syndrome virus (PRRSV) in serum containing 6.10 x 10(2) viral copies per microliter and influenza A virus in lung lavage fluid containing 2.08 x 10(6) viral copies per microliter. The Virochip also successfully detected porcine circovirus type 2 (PCV2) in serum containing 2.50 x 10(8) viral copies per microliter and porcine respiratory coronavirus (PRCV) in turbinate tissue homogenate. Collectively, the data in this report demonstrate that the Virochip can successfully detect pathogenic viruses frequently found in swine in a variety of solid and liquid specimens, such as turbinate tissue homogenate and lung lavage fluid, as well as antemortem samples, such as serum.

Flavour improvement might be achieved if fruits were harvested with some colour (to eliminate IG fruits) and/or stored at higher temperature with the ripening inhibitor 1-methylcyclopropene (1-MCP). RESULTS: 'Florida 47' tomatoes were harvested at GR (MG + IG), breaker (BR), turning (TR) and pink (PK) stages, treated (+) or not (-) with 1-MCP and stored at 13 and/or 18 degrees C. 1-MCP treatment resulted in a gain of up to 6 days of shelf life depending on harvest maturity and storage temperature. Storage at 18 degrees C rather than 13 degrees C resulted in an increase in internal red colour, soluble solids (SS)/titratable acidity (TA) ratio and levels of many volatiles studied. The shelf life of BR (+) MCP fruits stored at 13 degrees C was similar to that of MG fruits. IG fruits exhibited lowest levels of SS, TA and ten volatiles compared with BR fruits. CONCLUSION: Harvesting tomatoes with colour (BR), thereby eliminating IG fruits, and treating with 1-MCP resulted in better quality with adequate shelf life. Published 2011 by John Wiley & Sons, Ltd.

TI Evaluation of a Low-head Recirculating Aquaculture System Used for Rearing Florida Pompano to Market Size SO JOURNAL OF THE WORLD AQUACULTURE SOCIETY LA English DT Article ID BED BIOFILM REACTORS; MANAGEMENT; DESIGN AB A low-head recirculating aquaculture system (RAS) for the production of Florida pompano, Trachinotus carolinus, from juvenile to market size was evaluated. The 32.4-m3 RAS consisted of three dual-drain, 3-m diameter culture tanks of 7.8-m3 volume each, two 0.71-m3 moving bed bioreactors filled with media (67% fill with K1 Kaldness media) for biofiltration, two degassing towers for CO(2) removal and aeration, a drum filter with a 40-mu m screen for solids removal, and a 1-hp low-head propeller pump for water circulation. Supplemental oxygenation was provided in each tank by ultrafine ceramic diffusers and system salinity was maintained at 7.0 g/L. Juvenile pompano (0.043 kg mean weight) were stocked into each of the three tanks at an initial density of 1.7 kg/m3 (300 fish/tank). After 306 d of culture, the mean weight of the fish harvested from each tank ranged from 0.589 to 0.655 kg with survival ranging from 57.7 to 81.7%. During the culture period, the average water use per kilogram of fish was 3.26 or 1.82 m3 per fish harvested. Energy consumption per kilogram of fish was 47.2 or 22.4 kwh per fish harvested. The mean volumetric total ammonia nitrogen (TAN) removal rate of the bioreactors was 127.6 +/- 58.3 g TAN removed/m3 media-d with an average of 33.0% removal per pass. Results of this evaluation suggest that system modifications are warranted to enhance production to commercial levels (> 60 kg/m3).

The method provides uniform inoculum, which may reduce false negatives and the confounding effect of late maturity in field-grown plants. Seedlings of two cultivated varieties, five wild potato families and five families of complex hybrids were tested for VW symptoms after exposure to fungal suspensions and exudate from liquid cultures. The seedlings of the resistant cultivar and two resistant wild species exhibited fewer symptoms in response to fungal suspensions than the susceptible controls, indicating that seedlings can be scored for VW resistance or tolerance. Furthermore, exposure of seedlings to filter-sterilized exudates lacking the fungus elicited symptoms very similar to treatment with cultures containing VW condia. This result suggests that Vd (Verticillium dahliae Kleb.) liquid culture exudates may contain phytotoxins that can cause visible effects on the growth of certain genotypes. Overall, our results indicate that a greenhouse-based seedling assay can be used effectively to identify resistant or tolerant clones.

TI Lysine Acetylation Is a Widespread Protein Modification for Diverse Proteins in Arabidopsis SO PLANT PHYSIOLOGY LA English DT Article ID HISTONE H3 LYSINE-9; MASS-SPECTROMETRY; ESCHERICHIA-COLI; DNA METHYLATION; PHOSPHORYLATION; RESOLUTION; SUBUNIT; MUTATIONS; THALIANA; HETEROCHROMATIN AB Lysine acetylation (LysAc), a form of reversible protein posttranslational modification previously known only for histone regulation in plants, is shown to be widespread in Arabidopsis (Arabidopsis thaliana). Sixty-four Lys modification sites were identified on 57 proteins, which operate in a wide variety of pathways/processes and are located in various cellular compartments. A number of photosynthesis-related proteins are among this group of LysAc proteins, including photosystem II (PSII) subunits, light-harvesting chlorophyll a/b-binding proteins (LHCb), Rubisco large and small subunits, and chloroplastic ATP synthase (beta-subunit). Using two-dimensional native green/sodium dodecyl sulfate gels, the loosely PSII-bound LHCb was separated from the LHCb that is tightly bound to PSII and shown to have substantially higher level of LysAc, implying that LysAc may play a role in distributing the LHCb complexes. Several potential LysAc sites were identified on eukaryotic elongation factor-1A (eEF-1A) by liquid chromatography/mass spectrometry and using sequence- and modification-specific antibodies the acetylation of Lys-227 and Lys-306 was established. Lys-306 is contained within a predicted calmodulin-binding sequence and acetylation of Lys-306 strongly inhibited the interactions of eEF-1A synthetic peptides with calmodulin recombinant proteins in vitro. These results suggest that LysAc of eEF-1A may directly affect regulatory properties and localization of the protein within the cell. Overall, these findings reveal the possibility that reversible LysAc may be an important and previously unknown regulatory mechanism of a large number of nonhistone proteins affecting a wide range of pathways and processes in Arabidopsis and likely in all plants.

To investigate the impact of crop rotation on SOM composition, we sequentially extracted SOM by water (WEOM) and sodium pyrophosphate solution (PEOM) from different 3-year potato crop rotations with or without irrigation and quantified its elemental compositions. Different contents of P, Ca, Al, and Fe were observed among the PEOM fractions from fields with different crop rotations. Elemental contents in PEOM from irrigated treatments were consistently lower than those from the corresponding rainfed treatments. The structural features of these WEOM and PEOM samples were further characterized by Fourier transform-infrared (FT-IR) spectroscopy. Generally, the impacts of rotation and irrigation practices reflected on the changes of FT-IR band intensities in 3,020-2,800 cm(-1) (aliphatic groups) and 1,640-1,600 cm(-1) (aromatic compounds) of WEOM samples. The FT-IR spectroscopic analysis indicated that PEOM was more enriched in aliphatic, carboxyl, and aromatic compounds than WEOM. However, neither crop rotation nor irrigation changed the relative abundance of these functional groups in PEOM. This research improves our understanding of how the properties of SOM may be impacted by crop management. C1 [He, Zhongqi; Honeycutt, C.

TI Erodibility of a Sodic Soil Amended With Flue Gas Desulfurization Gypsum SO SOIL SCIENCE LA English DT Article DE Sodium adsorption ratio; exchangeable sodium percentage; infiltration; runoff; erosion; water dispersible clay ID QUALITY AB Sodic soils (Natraqualfs) represent a serious management problem in the lower Mississippi River Valley because of their dispersive nature. These soils are generally remediated with mined gypsum, but this is not economically feasible in the southeastern region. Instead, this study was conducted to determine if flue gas desulfurization (FGD) gypsum would effectively reduce the erodibility of these sodic soils. A-horizon samples (<2 mm) from a representative soil were characterized for basic physical and chemical properties. Additional subsamples (<8 mm) were amended with FGD gypsum at rates equivalent to 0, 3.36, 6.72, and 13.44 Mg ha(-1), packed to a depth of 7.6 cm in plexiglass cylinders, and subjected to simulated rainfall at an intensity of 64 mm h(-1) for 1 h. The erodibility data indicated that all amendment rates produced significant (P < 0.05) increases in percentage aggregation, aggregation index, and percentage transmission. These improvements in erodibility parameters led to a 71% increase in total infiltration, a 36% decrease in total runoff (RO), and a 77% decrease in soil loss at the 13.44-Mg ha(-1) rate relative to the 0 treatment. Sediment size distributions between 53 Km and 500 Km increased an average of 38%, and the less-than-5-mu m fraction decreased 21%. The results indicate that FGD gypsum will effectively increase infiltration and reduce RO and soil loss from sodic soils. The formation of larger sediment sizes also indicates that the quality of surface waters will be improved as the proportion of finer sediment in the RO is diminished.

TI Improving hydrologic predictions of a catchment model via assimilation of surface soil moisture SO ADVANCES IN WATER RESOURCES LA English DT Article DE Soil moisture; Hydrologic modeling; Data assimilation; Remote sensing ID ENSEMBLE KALMAN FILTER; LAND DATA ASSIMILATION; SEQUENTIAL ASSIMILATION; SIMULATIONS; RETRIEVALS; MISSION AB This paper examines the potential for improving Soil and Water Assessment Tool (SWAT) hydrologic predictions of root-zone soil moisture, evapotranspiration, and stream flow within the 341 km(2) Cobb Creek Watershed in southwestern Oklahoma through the assimilation of surface soil moisture observations using an Ensemble Kalman filter (EnKF). In a series of synthetic twin experiments assimilating surface soil moisture is shown to effectively update SWAT upper-layer soil moisture predictions and provide moderate improvement to lower layer soil moisture and evapotranspiration estimates. However, insufficient SWAT-predicted vertical coupling results in limited updating of deep soil moisture, regardless of the SWAT parameterization chosen for root-water extraction. Likewise, a real data assimilation experiment using ground-based soil moisture observations has only limited success in updating upper-layer soil moisture and is generally unsuccessful in enhancing SWAT stream flow predictions. Comparisons against ground-based observations suggest that SWAT significantly under-predicts the magnitude of vertical soil water coupling at the site, and this lack of coupling impedes the ability of the EnKF to effectively update deep soil moisture, groundwater flow and surface runoff. The failed attempt to improve stream flow prediction is also attributed to the inability of the EnKF to correct for existing biases in SWAT-predicted stream flow components.

The aim of this study was to investigate mRNA expression of 12- and 15-lipoxygenases (ALOX12, ALOX12B, ALOX15, ALOX15B) and the atypical ALOXE3 in human carotid atherosclerotic lesions, in relation to cerebrovascular symptoms and risk factors. The Biobank of Karolinska Endarterectomies (BiKE) collection of human carotid plaque tissue and associated clinical data was utilized (n = 132). Lesion mRNA levels were analyzed by TagMan qPCR (n = 132) and microarray hybridization (n = 77). Of the investigated mRNAs, only ALOX15B (15-LOX-2; epidermis-type 15-LOX) was readily detected in all plaque samples by qPCR, and thus suitable for quantitative statistical evaluation. ALOX12, ALOX12B, ALOX15 and ALOXE3 were detected with lower frequency and at lower levels, or virtually undetected. Microarray analysis confirmed ALOX15B as the most abundant 12- or 15-lipoxygenase mRNA in carotid lesions. Comparing plaques with or without attributable cerebrovascular symptoms (amaurosis fugax, transient ischemic attack, or stroke), ALOX15B mRNA levels were higher in symptomatic than asymptomatic plaques (1.31 [1.11-1.56], n = 102; and 0.79 [0.55-1.15], n = 30, respectively; p = 0.008; mean [95% CI], arbitrary units). Multiple regression analysis confirmed symptomatic/asymptomatic status as a significant determinant of ALOX15B mRNA levels, independently of potentially confounding factors. Immunohistochemical analyses showed abundant ALOX15B expression in macrophage-rich areas of carotid lesions, and lipidomic analyses demonstrated the presence of typical ALOX15B products in plaque tissue. In summary, we observed associations between high ALOX15B expression in carotid lesions and a history of cerebrovascular symptoms. These findings suggest a link between ALOX15B and atherothrombotic events that merits further investigation. (C) 2011 Elsevier Ireland Ltd. All rights reserved.

TI Association of gene variants with lipid levels in response to fenofibrate is influenced by metabolic syndrome status SO ATHEROSCLEROSIS LA English DT Article DE Lipid responses to fenofibrate; Metabolic syndrome; Gene-drug interaction; Triglyceride lowering; Increasing HDL-C ID APOLIPOPROTEIN-E POLYMORPHISM; ACTIVATED RECEPTOR-ALPHA; DIET NETWORK; RISK; DYSLIPIDEMIA; TRIGLYCERIDE; MANAGEMENT; CLUSTER; GOLDN AB Objective: Fenofibrate therapy reduces serum triglycerides (TG) and increases high-density lipoprotein-cholesterol (HDL-C) and thus addresses the atherogenic dyslipidemia associated with metabolic syndrome (MetS). Our hypothesis is that genetic factors contribute to the variability of lipid response to fenofibrate differently in subjects with MetS and without MetS. Methods: We investigated the association in 25 candidate genes with lipid responses to a 3-weeks trial on fenofibrate in subjects with and without MetS. We employed growth curve mixed models to generate the response phenotypes to fenofibrate in TG, HDL-C, and low-density lipoprotein-cholesterol (LDL-C) and examined the genetic associations accounting for family dependencies. Results: After correcting for multiple testing (p < 0.05) and accounting for significant differences in the association effect sizes between subjects with and without MetS (p < 0.05), variants of APOA5 (rs662799) and APOE (rs429358) were associated with HDL-C and LDL-C responses in MetS subjects, while APOA4 (rs675) was associated with TG response in non-MetS subjects. There was also suggestive evidence that MetS may interact with APOA4 (p = 0.017), APOA5 (p = 0.06), and APOE (p = 0.09) to the variation to lipid responses. Conclusions: Genetic effects that contributed to the variability of lipid responses to fenofibrate may differ in subjects with and without MetS. This research may provide guidance for more personalized and effective therapies. (C) 2011 Elsevier Ireland Ltd. All rights reserved.

TI Altered Folate Availability Modifies the Molecular Environment of the Human Colorectum: Implications for Colorectal Carcinogenesis SO CANCER PREVENTION RESEARCH LA English DT Article ID FOLIC-ACID SUPPLEMENTATION; COLONIC MUCOSAL CONCENTRATIONS; GENOMIC DNA METHYLATION; UNIVERSAL BEAD ARRAYS; DIETARY-FOLATE; BLOOD MEASUREMENTS; P53 EXPRESSION; STRAND BREAKS; CANCER-RISK; RAT COLON AB Low folate status increases colorectal cancer risk. Paradoxically, overly abundant folate supplementation, which is not uncommon in the United States, may increase risk. The mechanisms of these effects are unknown. We conducted two translational studies to define molecular pathways in the human colon altered either by folate supplementation or by dietary folate depletion (followed by repletion). In the first study, 10 healthy, at-risk volunteers (with documented stable/normal folate intake) received supplemental folic acid (1 mg/d) for 8 weeks. In the second study, 10 similar subjects were admitted to a hospital as inpatients for 12 weeks to study folate depletion induced by a low folate diet. A repletion regimen of folic acid (1 mg/d) was provided for the last 4 of these weeks. Both studies included an 8-week run-in period to ensure stabilized folate levels prior to intervention. We obtained 12 rectosigmoid biopsies (from 4 quadrants of normal-appearing mucosa 10-15 cm from the anal verge) at baseline and at measured intervals in both studies for assessing the primary endpoints: genome-wide gene expression, genomic DNA methylation, promoter methylation (depletion/repletion study only), and p53 DNA strand breaks. Serum and rectosigmoid folate concentrations accurately tracked all changes in folate delivery (P < 0.05). In the first study, gene array analysis revealed that supplementation upregulated multiple inflammation-and immune-related pathways in addition to altering several 1-carbon-related enzymes (P < 0.001). In the second study, folate depletion downregulated genes involved in immune response, inflammation, the cell cycle, and mitochondrial/energy pathways; repletion reversed most of these changes. However, changes in gene expression after repletion in the second study (involving immune response and inflammation) did not reach the levels seen after supplementation in the first study. Neither genomic nor promoter-specific DNA methylation changed during the course of the depletion/repletion protocol, and genomic methylation did not change with supplementation in the first study. p53 DNA strand breaks increased with depletion after 12 weeks. In sum, depletion downregulates, whereas repletion or supplementation upregulates pathways related to inflammation and immune response. These findings provide novel support to the concept that excessive folate supplementation might promote colorectal carcinogenesis by enhancing proinflammatory and immune response pathways. These results indicate that modest changes in folate delivery create substantial changes in the molecular milieu of the human colon. Cancer Prev Res; 4(4); 530-43. (C) 2011 AACR.

TI Estimation of real-time N load in surface water using dynamic data-driven application system SO ECOLOGICAL ENGINEERING LA English DT Article DE DDDAS; Nutrients; Real-time; River; Water quality ID PHOSPHORUS; LAKES; NITROGEN; PREDICTION AB Agricultural, industrial, and urban activities are the major sources for eutrophication of surface water ecosystems. Currently, determination of nutrients in surface water is primarily accomplished by manually collecting samples for laboratory analysis, which requires at least 24 h. In other words, little to no effort has been devoted to monitoring real-time variations of nutrients in surface water ecosystems due to the lack of suitable and/or cost-effective wireless sensors. However, when considering human health or instantaneous outbreaks such as algal blooms, timely water-quality information is very critical. In this study, we developed a new paradigm of a dynamic data-driven application system (DDDAS) for estimating the real-time loads of nitrogen (N) in a surface water ecosystem. This DDDAS consisted of the following components: (1) a Visual Basic (VB) program for downloading US Geological Survey real-time chlorophyll and discharge data from the internet; (2) a STELLA model for evaluating real-time N loads based on the relationship between chlorophyll and N as well as on river discharge; (3) a batch file for linking the VB program and STELLA model; and (4) a Microsoft Windows Scheduled Task wizard for executing the model and displaying outputs on a computer screen at selected schedules. The DDDAS was validated using field measurements with a very good agreement prior to its applications. Results show that the real-time loads of TN (total N) and NO(x) (nitrate and nitrite) varied from positive to negative with the maximums of 1727 kg/h TN and 118 kg/h NO(x) and the minimums of -2483 kg/h TN and -168 kg/h NO(x) at the selected site. The negative loads occurred because of the back flow of the river in the estuarine environment. Our study suggests that the DDDAS developed in this study was feasible for estimating the real-time variations of TN and NO(x) in the surface water ecosystem. Published by Elsevier B.V.

Brittain, Stuart TI A Method for Ensemble Wildland Fire Simulation SO ENVIRONMENTAL MODELING & ASSESSMENT LA English DT Article DE Wildland fire; Fire simulation; Decision support; Fire behavior; Risk assessment ID GROWTH-MODEL; TIME-SERIES; SPREAD; RISK AB An ensemble simulation system that accounts for uncertainty in long-range weather conditions and two-dimensional wildland fire spread is described. Fuel moisture is expressed based on the energy release component, a US fire danger rating index, and its variation throughout the fire season is modeled using time series analysis of historical weather data. This analysis is used to characterize the seasonal trend in ERC, autocorrelation of residuals, and daily standard deviation and stochastically generate artificial time series of afternoon fuel moisture. Daily wind speed and direction are sampled stochastically from joint probabilities of historical wind speed and direction for the date range of the fire simulation period. Hundreds or thousands of fire growth simulations are then performed using the synthetic fire weather sequences. The performance of these methods is evaluated in terms of the number of ensemble member simulations, one- versus two-dimensional fire spread simulations, and comparison with results from 91 fires occurring from 2007 to 2009. Simulations were found to be in consistent agreement with observations, but trends indicate that the ensemble average of simulated fire sizes were consistently larger than actual fires whereas the farthest extent burned by fires was underestimated.

Dendroctonus ponderosae provides an informative system because recent evidence suggests that distant populations produce hybrids with reproductive incompatibilities. Dendroctonus ponderosae shows an isolation-by-distance gene flow pattern allowing us to characterize the evolution of postzygotic isolation (e.g., hybrid inviability, hybrid sterility) by crossing populations along a continuum of geographic/genetic divergence. We found little evidence of hybrid inviability among these crosses. However, crosses between geographically distant populations produced sterile males (consistent with Haldane's rule). This effect was not consistent with the fixation of mutations in an isolation-by-distance pattern, but instead is spatially localized. These reproductive barriers are uncorrelated with a reduction in gene flow suggesting their recent development. Crosses between geographically proximal populations bounding the transition from compatibility to hybrid male sterility showed evidence of unidirectional reduction in hybrid male fecundity. Our study describes significant postzygotic isolation occurring across a narrow and molecularly cryptic geographic zone between the states of Oregon and Idaho. This study provides a view of the early stages of postzygotic isolation in a geographically widespread species.

Yet because sex chromosomes in many species are ancient, we lack empirical evidence of the earliest stages of this transition. We use QTL analysis to examine the genetic architecture of sexual dimorphism in subdioecious octoploid Fragaria virginiana. We demonstrate that the region housing the male-function locus controls the majority of quantitative variation in proportion fruit set, confirming the existence of a proto-sex chromosome, and houses major QTL for eight additional sexually dimorphic traits, consistent with theory and data from animals and plants with more advanced sex chromosomes. We also detected autosomal QTL, demonstrating contributions to phenotypic variation in sexually dimorphic traits outside the sex-determining region. Moreover, for proportion seed set we found significant epistatic interactions between autosomal QTL and the male-function locus, indicating sex-limited QTL. We identified linked QTL reflecting trade-offs between male and female traits expected from theory and positive integration of male traits. These findings indicate the potential for the evolution of greater sexual dimorphism. Involvement of linkage groups homeologous to the proto-sex chromosome in these correlations reflects the polyploid origin of F. virginiana and raises the possibility that chromosomes in this homeologous group were predisposed to become the sex chromosome.

We modeled the effects of this project on reducing landscape-level fire behavior at multiple time steps, up to nearly 30 years beyond treatment implementation. In addition, we modeled planned treatments under multiple diameter-limited thinning scenarios to assess potential impacts on fuel treatment effectiveness. The planned fuel treatments reduced modeled conditional burn probabilities substantially across the landscape relative to those for a scenario with no simulated treatments. This reduction relative to that for the no treatment landscape was evident approximately 20 years after simulated treatment implementation. Although diameter-limited thinning scenarios resulted in different residual forest stand structures, we detected no real differences in modeled landscape-level burn probabilities. The modeling adaptations we made with respect to fuel model selection and simulated ingrowth/regeneration over simulated time, as well as incorporation of variable winds in fire simulations, collectively contribute to a robust analysis of the study area.

SO FOREST SCIENCE LA English DT Article DE wood density; wood properties; repeated measure; nonlinear model; mixed effect model ID WOOD DENSITY; GROWTH; RADIATA; ANATOMY; AGE AB Ring specific gravity, earlywood and latewood specific gravity, and percent latewood were measured on cores collected at breast height from a thinned and fertilized midrotation loblolly pine (Pinus taeda L.) plantation in the lower Coastal Plain of North Carolina. The study was laid out in a randomized complete block design receiving four levels of nitrogen (N) fertilizer in 1984: 000 (control), 112, 224, and 336 kg/ha plus 28 kg/ha of phosphorus with each treatment. A consistent pattern of response was observed in latewood specific gravity (LWSG) after the application of different levels of fertilizer and used as a variable for modeling. The LWSG profiles of unfertilized trees followed a nonlinear relation with ring number from pith. A three-parameter asymptotic function was used to explain the LWSG profile of unfertilized trees with ring number as a covariate. Application of N reduced LWSG and was modeled using a two-parameter response function with year since fertilization as a covariate and separate parameter estimates for each fertilization level. On the basis of the model, the magnitude of maximum cumulative response was -0.025, -0.049, and -0.074 attained at 3.7, 1.9, and 0.8 years after fertilization for the 112, 224, and 336 kg/ha treatments, respectively.

TI Improving Tree Age Estimates Derived from Increment Cores: A Case Study of Red Pine SO FOREST SCIENCE LA English DT Article DE cross-dating; dendrochronology; Pinus resinosa; stand dynamics; tree age ID FOREST DISTURBANCE; STAND DYNAMICS; BLACK SPRUCE; GROWTH-RATE; REGENERATION; VARIABILITY; LANDSCAPE; HISTORY; CLIMATE; LEVEL AB Accurate tree ages are critical to a range of forestry and ecological studies. However, ring counts from increment cores, if not corrected for the years between the root collar and coring height, can produce sizeable age errors. The magnitude of errors is influenced by both the height at which the core is extracted and the growth rate. We destructively sampled saplings and small trees of red pine (Pinus resinosa Ait.) and combined within- and between-tree cross-dating to determine accurate rings counts and radial growth rates for 11 stem sections of each sample. We developed regression models to estimate age adjustment as a function of coring height and radial growth rate. We compared candidate models using corrected Akaike's information criterion scores, and we evaluated model performance by jackknife permutations. Application of our best-fit equations clearly improved age estimates: compared with unadjusted ring counts, our adjusted age estimates had normally distributed errors centered near 0, lower standard deviations, and a narrower range of values. Thus, these equations can be used to adjust ages of cored, mature trees occurring in these same settings. The methods used here may be applied to other shade-intolerant or mid-tolerant species where improved tree establishment dates are needed. FOR. SCI. 57(2):164-170.

A total of 16 BAC clones were sequenced producing 15,228 shotgun reads, corresponding to 11.2 X sequencing coverage, that were used to construct a contig of 12.18 Mb in length. MS markers were compared with previously deposited GenBank sequences to verify the existence of 423 potential MS candidate markers in the SLA-1 region. Evaluation of these polymorphisms confirmed 59 markers in MIPs, and the combined data including sequences from GenBank revealed 155 polymorphic MS markers. MS markers identified from this analysis can be used to provide an alternative method to direct typing for determining an individual's SLA-1 haplotype. (C) 2011 Elsevier Inc. All rights reserved.

The interaction between ligands of TLR3 and TLR9, poly I: C (an analog of viral double-stranded RNA) and CpG-ODN (a CpG-motif containing oligodeoxydinucleotide) on the inflammatory immune responses, including the production of nitric oxide (NO) and the expression of inducible NO synthase (iNOS), pro-inflammatory cytokines interleukin (IL)-1 beta and IL-6, and chemokines IL-8 and macrophage inflammatory protein (MIP)-1 beta, were investigated in chicken monocytes. The NO production was significantly higher when stimulated with a combination of CpG-ODN and poly I: C than with either CpG-ODN or poly I: C alone. Similarly, a significant synergistic effect by CpG-ODN and poly I: C was observed in the up-regulation of iNOS and IL-8 mRNA after 2 h and persisted up to 24 h. Although the combinatory treatment of CpG-ODN and poly I: C enhanced the expression of IL-1 beta, IL-6, and MIP-1 beta after 2 h stimulation, the synergism in the up-regulation of IL-1b and IL-6 mRNA was observed after 8-h and 24-h stimulation, respectively, whereas there was no synergistic effect on MIP-1 beta. Our results demonstrate that CpG-ODN synergizes with poly I: C to induce pro-inflammatory immune response in chicken monocytes.

TI Characterization of a new endogenous endo-beta-1,4-glucanase of Formosan subterranean termite (Coptotermes formosanus) SO INSECT BIOCHEMISTRY AND MOLECULAR BIOLOGY LA English DT Article DE Termite; Cellulase; Promoter; Phylogenetics; Biofuel ID CELLULASE GENE; RETICULITERMES-FLAVIPES; CELLULOLYTIC ACTIVITY; EXPRESSION; SHIRAKI; GUT; RHINOTERMITIDAE; ISOPTERA; ORIGIN; COLI AB The present work characterized a new endogenous cellulase (endo-beta-1,4-glucanase) gene, CfEG5, uncovered in the transcriptome of Formosan subterranean termite (Coptotermes formosanus). The full-length gene was cloned and sequenced. It is similar to the CfEG3a described earlier (Zhang et al., 2009) but not likely an allelic variant. GenomeWalker (TM) DNA walking analysis indicated that there may be one copy of CfEG5 and two copies of CfEG3a in the termite genome. As with CjEG3a, the transcript of CfEG5 was detected predominantly in the salivary gland based on quantitative RT-PCR. Phylogenetic analysis of translated amino acid sequence showed that the CfEG5 is more related to CaEG, derived from an Australian subterranean termite (Coptotermes acinaciformis), than CfEG3a and other cellulases from Coptotermes formosanus, Reticulitermes speratus, or Reticulitermes flavipes. Recombinant CfEG5, produced in Escherichia coli, was active against filter-paper cellulose, resulting in mostly cellobiose and cellotriose, similar to the enzymatic and biochemical properties of CfEG3a. These findings would lead to further investigation of both the evolutionary origin of eukaryotic cellulase genes and the evolutionary relationship of termite species. The cellulose-degrading enzyme is applicable for bioconversion of wood to simple sugars and production of biofuels. The recombinant cellulase should also be useful for designing and screening of inhibitors for the development of target-specific and environment-friendly bio-termicides. Published by Elsevier Ltd.

To understand the molecular mechanisms underlying detoxification of phytochemicals, insecticides and mycotoxins by this species, full-length CYP6AB11 cDNA was isolated from larval midguts using RACE PCR. Phylogenetic analysis of this insect cytochrome P450 monooxygenase established its evolutionary relationship to a P450 that selectively metabolizes imperatorin (a linear furanocoumarin) and myristicin (a natural methylenedioxyphenyl compound) in another lepidopteran species. Metabolic assays conducted with baculovirus-expressed P450 protein, P450 reductase and cytochrome b(5) on 16 compounds, including phytochemicals, mycotoxins, and synthetic pesticides, indicated that CYP6AB11 efficiently metabolizes imperatorin (0.88 pmol/min/pmol P450) and slowly metabolizes piperonyl butoxide (0.11 pmol/min/pmol P450). LC-MS analysis indicated that the imperatorin metabolite is an epoxide generated by oxidation of the double bond in its extended isoprenyl side chain. Predictive structures for CYP6AB11 suggested that its catalytic site contains a doughnut-like constriction over the heme that excludes aromatic rings on substrates and allows only their extended side chains to access the catalytic site. CYP6AB11 can also metabolize the principal insecticide synergist piperonyl butoxide (PBO), a synthetic methylenedioxyphenyl compound, albeit slowly, which raises the possibility that resistance may evolve in this species after exposure to synergists under field conditions.

Weekly inundative releases of a coccinellid predator (Coccinella undecimpunctata L. [Coleoptera: Coccinellidae]), a common green lacewing predator (Chrysoperla carnea Stephen [Neuroptera: Chrysopidae]), and a mirid predator (Macrolophus caliginosus [Wagner] [Hemiptera: Miridae]) were independently made in three vegetable crops (cabbage [Brassica oleracea var. capitata L.], cucumber [Cucumis sativus L.], and squash [Cucurbita pepo L.]) for the management of the sweetpotato whitefly. Approximately 1 million to 2.5 million larvae or nymphs of each predator were released in the vegetable crops during 20 weeks. Whitefly populations were reduced by approximate to 25%-45% during most of the season in each crop where each predator was released. The effect of each predator was similar on whitefly population reduction. Late in the season (October) when whitefly populations were low, generally no benefit was obtained from releasing the predators. Numbers of predators recovered during sampling in all crops were greatest for C. carnea, but this corresponded with the fact that more individuals of this predator were released than any other predator in the experiment. These results help define the utility of these natural enemies for managing B. tabaci in vegetable crops. C1 [Simmons, Alvin M.] ARS, USDA, US Vegetable Lab, Charleston, SC 29414 USA.

(Scrophulariales: Oleaceae), an invasive shrub in the United States, was studied in China. Five densities of adults were inoculated into 3-year-old potted Chinese privet plants in cages under field conditions for 1 month. Plants exposed to high densities of adults were severely damaged and the above-ground portions of some were killed, while the survival rates of adult A. tsekooni were comparatively high. The amount of new growth of the main stem, the number of new leaves, and oven-dried biomass were significantly reduced by the combined feeding of larvae and adults. Above-ground plant mortality was 100% when plants were exposed to 24 and 30 adults/plant. In this study A. tsekooni had a significant negative impact on Chinese privet growing in pots, which suggests that it may be a promising candidate for biological control of Chinese privet in the field in North America.

State and federal hatcheries are operating to achieve production goals but until recently those goals were not met. Hatchery mangers identified initiation of larvae to feed as the most critical rearing period and stated that mortality during this period can determine hatchery year class strength. The discontinuation of a commercial diet used at many hatcheries and the variety of diets used at other hatcheries exposed a need for information quantified through analytical research on the effects of different diets on survival and growth of larval pallid sturgeon. In 2007 we evaluated the effects of five diets [Corey High Pro and freeze dried Cyclop-eeze (FDC), Otohime (OTO), BioVita, BioVita and frozen Cyclop-eeze, BioVita and FDC] on larval survival and growth over 60 day. In 2008 we again evaluated five diets (OTO, OTO and FDC, OTO and freeze dried Artemia, OTO and live Artemia, and ARS experimental diet) for 30 day. In 2007, we determined a diet of OTO produced relatively high survival (54%) compared to other stand alone diets and found that supplementing BioVita with FDC improved survival (63%) compared to BioVita alone (14%). In 2008, we determined that OTO supplemented with FDC increased survival (92%) compared to OTO alone (72%). Information from this research may improve the efficiency of propagation by increasing survival and growth and may be beneficial to conservation propagation efforts directed at recovery of the species.

TI Milk Intake and Risk of Hip Fracture in Men and Women: A Meta-Analysis of Prospective Cohort Studies SO JOURNAL OF BONE AND MINERAL RESEARCH LA English DT Article DE HIP FRACTURE; MILK INTAKE; META-ANALYSIS; COHORT STUDIES ID RANDOMIZED-CONTROLLED-TRIALS; VITAMIN-D; CALCIUM INTAKE; DIETARY CALCIUM; OSTEOPOROTIC FRACTURES; PHYSICAL-ACTIVITY; BONE; PREVENTION; DENSITY; EUROPE AB Milk contains calcium, phosphorus, and protein and is fortified with vitamin D in the United States. All these ingredients may improve bone health. However, the potential benefit of milk on hip fracture prevention is not well established. The objective of this study was to assess the association of milk intake with risk of hip fracture based on a meta-analysis of cohort studies in middle-aged or older men and women. Data sources for this study were English and non-English publications via Medline (Ovid, PubMed) and EMBASE search up to June 2010, experts in the field, and reference lists. The idea was to compare prospective cohort studies on the same scale so that we could calculate the relative risk (RR) of hip fracture per glass of milk intake daily (approximately 300 mg calcium per glass of milk). Pooled analyses were based on random effects models. The data were extracted by two independent observers. The results show that in women (6 studies, 195,102 women, 3574 hip fractures), there was no overall association between total milk intake and hip fracture risk (pooled RR per glass of milk per day 0.99; 95% confidence interval [CI] 0.96-1.02; Q-test p=.37). In men (3 studies, 75,149 men, 195 hip fractures), the pooled RR per daily glass of milk was 0.91 (95% CI 0.81-1.01). Our conclusion is that in our meta-analysis of cohort studies, there was no overall association between milk intake and hip fracture risk in women but that more data are needed in men.

Eligible participants were interviewed in the home by bilingual interviewers in either Spanish or English. Scales included topics ranging from general background to depressive symptomatology. Respiratory disease was self-reported and checked against prescribed medication. More than one-third (37.8%) of subjects reported doctor-diagnosed RD. A final binary logistical regression model (N = 850), which was adjusted for potential confounders (sex, age, education, poverty) showed that RD was significantly associated with psychological acculturation (OR = 1.97, P = 0.005), depressive symptomatology (OR = 1.52, P = 0.03) high perceived stress score (OR = 1.97, P = 0.009), and current smoking (OR = 1.61, P = 0.03). Significant inverse associations included a high level of language acculturation (OR = 0.65, P = 0.03), light (OR = 0.67, P = 0.01) and moderate to heavy physical activity versus sedentary physical activity (OR = 0.40, P = 0.03). We found self reported physician diagnosed RD was associated with high perceived stress and depression, as well as higher levels of psychological acculturation. Longitudinal research is needed to determine if there is a causal pathway for these associations. C1 [Brugge, Doug] Tufts Univ, Sch Med, Dept Publ Hlth & Family Med, Boston, MA 02111 USA.

TI Dietary Acid Load Is Not Associated with Lower Bone Mineral Density Except in Older Men SO JOURNAL OF NUTRITION LA English DT Article ID PHYSICAL-ACTIVITY; HEART-DISEASE; UNITED-STATES; HIP FRACTURE; I LEVELS; PROTEIN; WOMEN; HEALTH; CALCIUM; PREMENOPAUSAL AB High dietary acid load may be detrimental. to pone mineral density (BMD), although sufficient calcium intake might neutralize this effect In observational studies, the association between BMD and dietary acid load, estimated by net endogenous acid production (NEAP) and potential renal acid load (PRAL), has been inconsistent, and the potential mod fying effect of calcium,intake has rot been assessed. We therefore examined the cross-sectional associations of estimated NEAP and PRAL with BMD in the Framingham Osteoporosis Study. We hypothesized that higher estimated NEAP and PRAL would be associated w th ower BMD, but only among those with total calcium intake < 800 mg/d RMD of the femoral neck and lumbar spine was measured, and estimated NEAP and PRAL were ca culated via FFQ among 1069 Framingham Original (1988-1989. 19921993: 62% women, mean age 76 y) and 2919 Offspring (1996-2001; 56% women, mean age 60 y) cohort participants. Cohort- and sex-specific ANCOVA was used to calculate multivar able-adjusted mean BMD for estimated NEAP and PRAL quartiles. Assuming no uncontroled confounding, estimated NEAP, but not PRAL, was inversely associated with femoral neck BMD (P-trend = 0.04) in Original cohortsmen, whereas neither was associated w th lumbar spine BMD. Estimated NEAP and PRAL were not associated with BMD a: any site among Original cohort women or Offspring cohort men and women. There were no significant interactions between either estimated NEAP or PRAL and total calcium intake. These results suggest that, with a possible exception of older men, dietary acid load does not have a measureable negative effect on bone health, regardless of total calcium intake. J.

Tie goal was to examine the interaction o MTHFR variants with d etary fatty acids influencing plasma Hey in 995 Bostor Pier to Rican adults. We found that plasma Hcy concentration was negatively correlated with (n-3) PUFA intake (r = -0.117; P - 0.022), and the rat o of (n-3):(n-6) PUPA in the diet (r = -0.1 22; P = 0.009). Further, 2 functional MTHER variarts, 1298A>C and 677C>T, which are not in linkage disequilibrium in this population, were significantly associated with hypertension (OR = 1.72. P = 0.024, and OR = 1.60. P = 0 002, respectively). In addition, :he 1298A>C variant was sigmficantly associated with CVD (OR = 3.32; P = 0.030). Importantly. this variant exhibited significant interactions with intakes of total and (n-6) PUFA and the (n-3):(n-6) PUPA ratio of the d e:. The plasma Hcy concentration of carriers of risk allele 1298C was greater than that of roncarr ers only when participants had consumed a high-PUFA diet (>7.8% energy) but was not greater when :hey had low intake of PUFA (<= 7.8% energy). In addition, participants with combined aerotypes of both SNP (677 : with 1298 AC or CC) who consumed high levels of (n-3) PUFA (>0.66% energy) had lower plasma Hcy compared with :hose who had the same genotype and consumed low levels of (n-3) PUFA (>0.66% energy). Our study suggests that dietary PJFA intake modulates the ef ect of 2 MIHFR variants or plasma Hcy in Boston Puerto Rican adults. J. Nutr. 141: 654-659, 2011.

TI A Human Model of Selenium that Integrates Metabolism from Selenite and Selenomethionine SO JOURNAL OF NUTRITION LA English DT Article ID HUMAN-BODY FLUIDS; SELENOPROTEIN-P; CONTAINING PROTEINS; MASS-SPECTROMETRY; KINETIC-MODEL; RED-CELL; PLASMA; SPECIATION; WOMEN; CHROMATOGRAPHY AB Selenium (Se) metabolism is affected by its chemical form in foods and by its incorporatior (specific vs nonspecific) into multiple proteins. Moor:lino Se kinetics may clarify the impact of form or metabolism. Although the kinetics of Se forms have been compared in different participants, or the same participants at different times, direct comparisons of their respective metabolism in :he same participants have rot been made. The aim of this study was to simultaneous y compare kinetics of absorbed Se from inorganic selerite (Sol) and organic selenomethionine (SeMet) in healthy participants (n= 31). After oral administration of staple solopic trace's of each form, urine and feces were collected for 12 d and blood was sampled over 4 mo. Tracer enrichment was determined by isotope-dilutior-GC-MS. Using WinSAAM, a compartmental model was fited to the data Within 30 mn of ingest on, Se from both forms entered a common poo., and metabolism was similar for severa days before diverging. Slow y turning-over pools were required in tissues and plasma for Se derived from SeMet to account for its 3-times-higher incorporation into RBC compared with Se from Sal; these presumably represent nonspecific incorporation of SeMet into proteins. Pool sizes and transport rates were determined and comparea by form and gender. The final model consisted of 11 plasma pools, 2 pools and a delay in RBC, and extravascular pools for recycling of Se back into plasma. This model will be used to evaluate charges in Se metabolism following long-term (2 y) Se supplementation. J. Nutr. 141: 708-717. 2011.

Seeds are protein-rich, and have been the subject of many mass spectrometry-based analyses. Seed storage proteins (SSP), which are transient depots for reduced nitrogen, have been studied for decades by cell biologists, and many of the complicated aspects of their processing, assembly, and compartmentation are now well understood. Unfortunately, the abundance and complexity of the SSP requires that they be avoided or removed prior to gel-based analysis of non-SSP. While much of the extant data from MS-based proteomic analysis of seeds is descriptive, it has nevertheless provided a preliminary metabolic picture explaining much of their biology. Contemporary studies are moving more toward analysis of protein interactions and posttranslational modifications, and functions of metabolic networks. Many aspects of the biology of seeds make then an attractive platform for heterologous protein expression. Herein we present a broad review of the results from the proteomic studies of seeds, and speculate on a potential future research directions. (C) 2010 Elsevier B.V. All rights reserved.

TI Topography-mediated controls on local vegetation phenology estimated from MODIS vegetation index SO LANDSCAPE ECOLOGY LA English DT Article DE Vegetation phenology; MODIS; NDVI; Coweeta; Climate change ID CARBON SEQUESTRATION; CLIMATIC VARIABILITY; LEAF-AREA; BUD BURST; FOREST; SATELLITE; TEMPERATURE; MOUNTAINS; ELEVATION; PATTERNS AB Forest canopy phenology is an important constraint on annual water and carbon budgets, and responds to regional interannual climate variation. In steep terrain, there are complex spatial variations in phenology due to topographic influences on microclimate, community composition, and available soil moisture. In this study, we investigate spatial patterns of phenology in humid temperate forest as a function of topography. Moderate-resolution imaging spectro-radiometer (MODIS) vegetation indices are used to derive local patterns of topography-mediated vegetation phenology using a simple post-processing analysis and a non-linear model fitting. Elevation has the most explanatory power for all phenological variables with a strong linear relationship with mid-day of greenup period, following temperatures lapse rates. However, all other phenological variables show quadratic associations with elevation, reflecting an interaction between topoclimatic patterns of temperature and water availability. Radiation proxies also have significant explanatory power for all phenological variables. Though hillslope position cannot be adequately resolved at the MODIS spatial resolution (250 m) to discern impacts of local drainage conditions, extended periods of greenup/senescence are found to occur in wet years. These findings are strongly supported by previous field measurements at different topographic positions within the study area. The capability of detecting topography-mediated local phenology offers the potential to detect vegetation responses to climate change in mountainous terrain. In addition, the large, local variability of meteorological and edaphic conditions in steep terrain provides a unique opportunity to develop an understanding of canopy response to the interaction of climate and landscape conditions.

Oliver TI Almond consumption improved glycemic control and lipid profiles in patients with type 2 diabetes mellitus SO METABOLISM-CLINICAL AND EXPERIMENTAL LA English DT Article ID HEART-DISEASE RISK; INSULIN SENSITIVITY; POSTPRANDIAL GLYCEMIA; HEALTHY-INDIVIDUALS; METABOLIC SYNDROME; HIGH-CARBOHYDRATE; CROSSOVER TRIAL; DOSE-RESPONSE; BODY-WEIGHT; LONG-TERM AB Almond consumption is associated with ameliorations in obesity, hyperlipidemia, hypertension, and hyperglycemia. The hypothesis of this 12-week randomized crossover clinical trial was that almond consumption would improve glycemic control and decrease the risk for cardiovascular disease in 20 Chinese patients with type 2 diabetes mellitus (T2DM) (9 male, 11 female; 58 years old; body mass index, 26 kg/m(2)) with mild hyperlipidemia. After a 2-week run-in period, patients were assigned to either a control National Cholesterol Education Program step II diet (control diet) or an almond diet for 4 weeks, with a 2-week washout period between alternative diets. Almonds were added to the control diet to replace 20% of total daily calorie intake. Addition of approximately 60 g almonds per day increased dietary intakes of fiber, magnesium, polyunsaturated fatty acid, monounsaturated fatty acid, and vitamin E. Body fat determined with bioelectrical impedance analysis was significantly lower in patients consuming almonds (almonds vs control: 29.6% vs 30.4%). The almond diet enhanced plasma a-tocopherol level by a median 26.8% (95% confidence intervals, 15.1-36.6) compared with control diet. Furthermore, almond intake decreased total cholesterol, low-density lipoprotein cholesterol, and the ratio of low-density lipoprotein cholesterol to high-density lipoprotein cholesterol by 6.0% (1.6-9.4), 11.6% (2.8-19.1), and 9.7% (0.3-20.9), respectively. Plasma apolipoprotein (apo) B levels, apo B/apo A-1 ratio, and nonesterified fatty acid also decreased significantly by 15.6% (5.1-25.4), 17.4% (2.8-19.9), and 5.5% (3.0-14.4), respectively. Compared with subjects in the control diet, those in the almond diet had 4.1% (0.9-12.5), 0.8% (0.4-6.3), and 9.2% (4.4-13.2) lower levels of fasting insulin, fasting glucose, and homeostasis model assessment of insulin resistance index, respectively. Our results suggested that incorporation of almonds into a healthy diet has beneficial effects on adiposity, glycemic control, and the lipid profile, thereby potentially decreasing the risk for cardiovascular disease in patients with type 2 diabetes mellitus.

TI Chemosensitization of Aflatoxigenic Fungi to Antimycin A and Strobilurin Using Salicylaldehyde, a Volatile Natural Compound Targeting Cellular Antioxidation System SO MYCOPATHOLOGIA LA English DT Article DE Salicylaldehyde; Aspergillus; Antioxidation system; Mycotoxin; Antifungal; Chemosensitization ID VACUOLAR H+-ATPASE; SACCHAROMYCES-CEREVISIAE; DRUG-RESISTANCE; STRESS; YEAST; ASPERGILLUS; TOLERANCE; AGENTS; BIOSYNTHESIS; SENSITIVITY AB Various species of fungi in the genus Aspergillus are the most common causative agents of invasive aspergillosis and/or producers of hepato-carcinogenic mycotoxins. Salicylaldehyde (SA), a volatile natural compound, exhibited potent antifungal and anti-mycotoxigenic activities to A. flavus and A. parasiticus. By exposure to the volatilized SA, the growth of A. parasiticus was inhibited up to 10-75% at 9.5 mM a parts per thousand currency sign SA a parts per thousand currency sign 16.0 mM, while complete growth inhibition was achieved at 19.0 mM a parts per thousand currency sign SA. Similar trends were also observed with A. flavus. The aflatoxin production, i.e., aflatoxin B-1 and B-2 (AFB(1), AFB(2)) for A. flavus and AFB(1), AFB(2), AFG(1), and AFG(2) for A. parasiticus, in the SA-treated (9.5 mM) fungi was reduced by similar to 13-45% compared with the untreated control. Using gene deletion mutants of the model yeast Saccharomyces cerevisiae, we identified the fungal antioxidation system as the molecular target of SA, where sod1 Delta [cytosolic superoxide dismutase (SOD)], sod2 Delta (mitochondrial SOD), and glr1 Delta (glutathione reductase) mutants showed increased sensitivity to this compound. Also sensitive was the gene deletion mutant, vph2 Delta, for the vacuolar ATPase assembly protein, suggesting vacuolar detoxification plays an important role for fungal tolerance to SA. In chemosensitization experiments, co-application of SA with either antimycin A or strobilurin (inhibitors of mitochondrial respiration) resulted in complete growth inhibition of Aspergillus at much lower dose treatment of either agent, alone. Therefore, SA can enhance antifungal activity of commercial antifungal agents required to achieve effective control. SA is a potent antifungal and anti-aflatoxigenic volatile that may have some practical application as a fumigant.

The GI is a kinetic parameter that reflects the ability of carbohydrate (CHO) contained in consumed foods to raise blood glucose in vivo. Newer nutritional, clinical, and experimental data link intake of lower dietary GI foods to favorable outcomes of chronic diseases, and compel further examination of the record. Based upon the new information there are two specific questions: 1) should the GI concept be promoted as a way to prolong health, and 2) should food labels contain GI information? Further, what are the remaining concerns about methodological issues and consistency of epidemiological data and clinical trials that need to be resolved in order to exploit the benefits of consuming lower GI diets? These issues are addressed in this review. C1 [Chiu, Chung-Jung; Taylor, Allen] Tufts Univ, Jean Mayer USDA, Human Nutr Res Ctr Aging, Boston, MA 02111 USA.

Increasing Se content in food crops offers an effective approach to reduce the widespread selenium deficiency problem in many parts of the world. In this study, we evaluated 30 diverse accessions of lettuce (Lactuca sativa L.) for their capacity to accumulate Se and their responses to different forms of Se in terms of plant growth, nutritional characteristics, and gene expression. Lettuce accessions responded differently to selenate and selenite treatment, and selenate is superior to selenite in inducing total Se accumulation. At least over twofold change in total Se levels between cultivars with high and low Se content was found. Synergistic relationship between Se and sulfur accumulation was observed in nearly all accessions at the selenate dosage applied. The change in shoot biomass varied between lettuce accessions and the forms of Se used. The growth-stimulated effect by selenate and the growth-inhibited effect by selenite were found to be correlated with the alteration of antioxidant enzyme activities. The different ability of lettuce accessions to accumulate Se following selenate treatment appeared to be associated with an altered expression of genes involved in Se/S uptake and assimilation. Our results provide important information for the effects of different forms of Se on plant growth and metabolism. They will also be of help in selecting and developing better cultivars for Se biofortification in lettuce.

Sham and FMG inoculations were administered at 12 wk (before lay) or 22 wk (onset of lay), dietary treatments [basal control diet (BCD); BCD with 0.75% supplemental PF (LPFD); BCD with 1.50% supplemental PF (HPFD); HPFD additionally supplemented with 0.013% PHY and 0.025% 25(OH)D] were initiated at 20 wk of age, and organ characteristics were determined at 58 wk of age. In proportion to small intestine weight, jejuna were heavier in birds inoculated at 22 wk rather than at 12 wk of age. In hens inoculated at 22 wk of age, percentage of infundibulum weight was increased by FMG. The proportional length of infundibula in birds fed HPFD with PHY and 25(OH)D was longer than in those fed LPFD. In birds inoculated with FMG at 22 wk of age, BW was greater in those fed HPFD with or without added PHY and 25(OH)D in comparison with those fed LPFD, whereas LPFD increased percentage of oviduct and magnum weights when compared with the HPFD and BCD groups, respectively. Percentage of duodenum weight in birds that were fed HPFD with PHY and 25(011)D was greater compared with those fed LPFD in the wk 22 sham and wk 12 FMG inoculation groups, but was also greater than in those fed BCD in the wk 12 FMG inoculation group. Conversely, percentage of duodenum weight was greater in birds fed LPFD compared with those fed HPFD after a wk 22 FMG inoculation. However, despite the effects of the supplemental combination of 1.50% PF, PHY, and 25(OH)D on the oviduct and small intestine structures, it did not result in a subsequent influence on layer performance, as indicated in a previous companion report.

In each experiment, 1,440 male and female broilers were randomly distributed into 96 floor pens (15 birds/pen; 8 replicate pens/treatment) sexed separately and were fed 6 levels of AME(n) ranging from 3,140 to 3,240 kcal/kg in increments of 20 kcal of AME(n)/kg, resulting in a 6 x 2 factorial arrangement of treatments. Body weight gain, feed intake, feed conversion, AME(n) intake, AME(n) intake per BW gain, plasma 5-triiodothyronine and thyroxine concentrations, mortality, and meat yields were evaluated during experimentation. Average temperature and RH were 20.3 degrees C and 49.0% for experiment 1 and 26.1 degrees C and 66.6% for experiment 2. In experiment 1, broilers fed progressive additions of AME(n) had lower (P <= 0.02) feed intake, feed conversion, and caloric conversion. Progressive increments of AME(n) did not influence plasma 5-triiodothyronine and thyroxine concentrations, carcass yield, or breast meat yield. No AME(n) x sex interactions were observed in experiment 1. In experiment 2, AME(n) x sex linear interactions (P <= 0.04) were observed for BW gain, caloric conversion, carcass weight, and total breast weight. Male broilers responded more to higher AME(n) levels than did female broilers. These data indicate that AME(n) needed for growth performance of broilers from 36 to 47 d of age differed between experiments. C1 [Dozier, W. A., III; Gehring, C.

TI Campylobacter, Salmonella, and Escherichia coli on broiler carcasses subjected to a high pH scald and low pH postpick chlorine dip SO POULTRY SCIENCE LA English DT Article DE Campylobacter; Salmonella; scald; pH; chlorine ID CROSS-CONTAMINATION; CHICKEN CARCASSES; DEATH RATES; ACETIC-ACID; WATER PH; POULTRY; TYPHIMURIUM; JEJUNI; SKIN; BACTERIA AB The objective of this study was to determine the individual and combined effects of a high pH scald and a postpick chlorine dip on bacteria present on broiler carcasses. In each of 3 replications, a flock was sampled at several sites within a commercial broiler processing plant. Carcasses were sampled by whole carcass rinse before and after treated scalding at mean pH 9.89 or control scalding at mean pH 6.88. Other carcasses from the same flock run on both the treated and control scald lines were collected and sampled before and after a chlorine dip tank operated at mean total chlorine level of 83.3 mg/kg and pH 6.04. Rinses were cultured for numbers of Campylobacter and Escherichia coli and presence or absence of Salmonella. High pH scald was more effective than standard scald to lessen the prevalence and numbers of Campylobacter on broiler carcasses; a lower prevalence was maintained through the postpick chlorine dip tank. The pH of the scald tank made no difference in numbers of E. coli recovered from broiler carcasses at any tested point on the processing line. High pH scald was not more effective than standard scald to lessen Salmonella prevalence. Furthermore, it is unclear why the postpick chlorine dip effectively lessened Salmonella prevalence on only the control scald line. Although no evidence exists that these treatments have an additive effect when used in series, each treatment shows some promise individually. Further optimization may result in more effective decontamination of broiler carcasses. C1 [Berrang, M. E.; Windham, W. R.; Meinersmann, R. J.] ARS, USDA, Russell Res Ctr, Athens, GA 30605 USA.

Reflectance measurements for 85 breast filets were recorded over the 400 to 2,498 nm wavelength range at 0.5-nm intervals and 32 scans. Chemometric analysis was performed utilizing Savitzky-Golay derivative processing and multiplicative scatter correction. Both partial least squares regression and discriminant analysis were used to develop calibration models tested by cross-validation. Partial least squares regression modeling resulted in coefficients of determinants of 0.72, 0.67, and 0.62 for WHC, pH, and lightness (L*) values, respectively. The mean spectra of samples categorized as either high or low WHC, pH, and L* showed significant differences between absorption peaks between 400 to 800 nm and between 1,400 to 2,500 nm (associated with heme pigments and water absorption, respectively). The results showed potential use of visible near-infrared spectroscopy as a predictor of WHC in pale broiler breast meat.

Transgenic events had different levels of down-regulation of two genes encoding 4-coumarate:coenzyme A ligase (4CL). Two-year-old trees were characterized after growing either as free-standing trees in the field or as supported by stakes in a greenhouse. In free-standing trees, a 20 to 40% reduction in lignin content was associated with increased xylem vulnerability to embolism, shoot dieback and mortality. In staked trees, the decreased biomechanical demands on the xylem was associated with increases in the leaf area to sapwood area ratio and wood specific conductivity (k(s)), and with decreased leaf-specific conductivity (k(l)). These shifts in hydraulic architecture suggest that the bending stresses perceived during growth can affect traits important for xylem water transport. Severe 4CL-downregulation resulted in the patchy formation of discoloured, brown wood with irregular vessels in which water transport was strongly impeded. These severely 4CL-downregulated trees had significantly lower growth efficiency (biomass/leaf area). These results underscore the necessity of adequate lignification for mechanical support of the stem, water transport, tree growth and survival.

TI The Marine Sponge-Derived Polyketide Endoperoxide Plakortide F Acid Mediates Its Antifungal Activity by Interfering with Calcium Homeostasis SO ANTIMICROBIAL AGENTS AND CHEMOTHERAPY LA English DT Article ID YEAST SECRETORY PATHWAY; GENOME-WIDE ANALYSIS; SACCHAROMYCES-CEREVISIAE; BIOACTIVE PEROXIDES; CYCLIC PEROXIDES; GENE-EXPRESSION; ION-PUMP; CALCINEURIN; CA2+; TRANSPORT AB Plakortide F acid (PFA), a marine-derived polyketide endoperoxide, exhibits strong inhibitory activity against the opportunistic fungal pathogens Candida albicans, Cryptococcus neoformans, and Aspergillus fumigatus. In the present study, transcriptional profiling coupled with mutant and biochemical analyses were conducted using the model organism Saccharomyces cerevisiae to investigate the mechanism of action of this compound. PFA elicited a transcriptome response indicative of a Ca(2+) imbalance, affecting the expression of genes known to be responsive to altered cellular calcium levels. Several additional lines of evidence obtained supported a role for Ca(2+) in PFA's activity. First, mutants lacking calcineurin and various Ca(2+) transporters, including pumps (Pmr1 and Pmc1) and channels (Cch1 and Mid1), showed increased sensitivity to PFA. In addition, the calcineurin inhibitors FK506 and cyclosporine strongly enhanced PFA activity in wild-type cells. Furthermore, PFA activated the transcription of a lacZ reporter gene driven by the calcineurin-dependent response element. Finally, elemental analysis indicated a significant increase in intracellular calcium levels in PFA-treated cells. Collectively, our results demonstrate that PFA mediates its antifungal activity by perturbing Ca(2+) homeostasis, thus representing a potentially novel mechanism distinct from that of currently used antifungal agents.

Recently, several unique anti-Campylobacter BCNs have been identified from commensal bacteria isolated from chicken intestines. These BCNs dramatically reduced C. jejuni colonization in poultry and are being directed toward on-farm control of Campylobacter. However, no information concerning prevalence, development, and mechanisms of BCN resistance in Campylobacter exists. In this study, susceptibilities of 137 C. jejuni isolates and 20 C. coli isolates to the anti-Campylobacter BCNs OR-7 and E-760 were examined. Only one C. coli strain displayed resistance to the BCNs (MIC, 64 mu g/ml), while others were susceptible, with MICs ranging from 0.25 to 4 mu g/ml. The C. coli mutants resistant to BCN OR-7 also were obtained by in vitro selection, but all displayed only low-level resistance to OR-7 (MIC, 8 to 16 mu g/ml). The acquired BCN resistance in C. coli could be transferred at intra-and interspecies levels among Campylobacter strains by biphasic natural transformation. Genomic examination of the OR-7-resistant mutants by using DNA microarray and random transposon mutagenesis revealed that the multidrug efflux pump CmeABC contributes to both intrinsic resistance and acquired resistance to the BCNs. Altogether, this study represents the first report of and a major step forward in understanding BCN resistance in Campylobacter, which will facilitate the development of effective BCN-based strategies to reduce the Campylobacter loads in poultry.

The results showed that C. jejuni was extremely sensitive to treatment with ZnO nanoparticles. The MIC of ZnO nanoparticles for C. jejuni was determined to be 0.05 to 0.025 mg/ml, which is 8- to 16-fold lower than that for Salmonella enterica serovar Enteritidis and Escherichia coli O157:H7 (0.4 mg/ml). The action of ZnO nanoparticles against C. jejuni was determined to be bactericidal, not bacteriostatic. Scanning electron microscopy examination revealed that the majority of the cells transformed from spiral shapes into coccoid forms after exposure to 0.5 mg/ml of ZnO nanoparticles for 16 h, which is consistent with the morphological changes of C. jejuni under other stress conditions. These coccoid cells were found by ethidium monoazide-quantitative PCR (EMA-qPCR) to have a certain level of membrane leakage. To address the molecular basis of ZnO nanoparticle action, a large set of genes involved in cell stress response, motility, pathogenesis, and toxin production were selected for a gene expression study. Reverse transcription-quantitative PCR (RT-qPCR) showed that in response to treatment with ZnO nanoparticles, the expression levels of two oxidative stress genes (katA and ahpC) and a general stress response gene (dnaK) were increased 52-, 7-, and 17-fold, respectively. These results suggest that the antibacterial mechanism of ZnO nanoparticles is most likely due to disruption of the cell membrane and oxidative stress in Campylobacter.

The strain FBR5 was chosen because of its ability to ferment both hexose and pentose sugars under semi-anaerobic conditions without using antibiotics. The average ethanol produced from the available sugars (21.9-47.8 g/L) ranged from 8.8 to 17.3 g/L (0.28-0.45 g/g available sugars, 0.31-0.48 g/g sugar consumed) with ethanol productivity of 0.27-0.78 g l(-1) h(-1) in a set of 14 continuous culture (CC) runs (16-105 days). During these CC runs, no loss of ethanol productivity was observed. This is the first report on the continuous production of ethanol by the recombinant bacterium from a lignocellulosic hydrolysate.

Recently, 11-hydroxy-O-methylsterigmatocystin (HOMST) was suggested to be a later precursor involved in the conversion of OMST to AFB(1), and conversion of HOMST to AFB(1) was catalyzed by OrdA enzyme. However, the involvement of HOMST in AFG(1) formation has not been determined. In this work, HOMST was prepared by incubating OrdA-expressing yeast with OMST. Feeding Aspergillus parasiticus with HOMST allowed production of AFG(1) as well as AFB(1). In cell-free systems, HOMST was converted to AFG(1) when the microsomal fraction, the cytosolic fraction from A. parasiticus, and yeast expressing A. parasiticus OrdA were added. These results demonstrated (1) HOMST is produced from OMST by OrdA, (2) HOMST is a precursor of AFG(1) as well as AFB(1), and (3) three enzymes, OrdA, CypA, and NadA, and possibly other unknown enzymes are involved in conversion of HOMST to AFG(1).

This study presents estimates of the likelihood of successful entry for alien forest insect species at more than 3,000 urban areas in the contiguous United States (US). To develop these location-specific estimates, we first utilized historical merchandise imports and insect incursions data to estimate an annual US rate of alien insect species establishment. Next, we used historical pest interception data to calculate the proportion of all insects arriving at US ports of entry that are associated with forest hosts. We then combined these results to estimate a nationwide establishment rate specifically for alien forest insects. Finally, we employed international and domestic commodity flow networks to allocate this nationwide rate to individual US urban areas. For 2010, we estimated the nationwide rate as 1.89 new alien forest insect species per year. While the establishment rates observed at most urban areas were low (< 0.005 new species/year), for a few select areas the rates predict new alien forest insect species establishments every 5-15 years. This national-scale assessment provides a realistic depiction of human-assisted establishment potential in the US as well as functional inputs for quantitative models of invasion. Overall, these analyses support broad-scale biosecurity and management strategies. C1 [Koch, Frank H.] N Carolina State Univ, Dept Forestry & Environm Resources, Res Triangle Pk, NC 27709 USA.

Biodegradability of pot type A (composed of 100% polylactic acid (PLA)) was very low (13 +/- 3%) compared to literature values for other PLA materials. Near infrared spectroscopy (NIRS) results suggest that the PLA undergoes chemical structural changes during polymer extrusion and injection molding. These changes may be the basis of the low biodegradability value. Biodegradability of pot types B (containing 5% poultry feather, 80% PLA, 15% starch), and C (containing 50% poultry feather, 25% urea, 25% glycerol), were 53 +/- 2% and 39 +/- 3%, respectively. More than 85% of the total biodegradation of these bioplastics occurred within 38 days. NIRS results revealed that poultry feather was not degraded during composting. Published by Elsevier Ltd.

We have identified the genes and associated metabolic pathways involved in the water-deficit stress response in leaf and root. Gene expression profiles were developed for leaf and root tissues subjected to slow-onset water deficit under controlled, glasshouse conditions. The water-deficit stress was characterized by leaf water potential of -23.1 bars for stressed tissue compared to -8.7 bars for fully-irrigated control plants and a corresponding decrease in net carbon assimilation to approximately 60% of the rates seen in the irrigated controls (30.3 +/- A 4.7 mu mol CO(2) m(-2) s(-1) compared to 17.8 +/- A 5.9 mu mol CO(2) m(-2) s(-1)). Profiling experiments revealed 2,106 stress-responsive transcripts, 879 classified as stress-induced, 1,163 stress-repressed, and 64 showed reciprocal expression patterns in root and leaf. The majority of stress-responsive transcripts had tissue-specific expression patterns and only 173 genes showed similar patterns of stress responsive expression in both tissues. A variety of putative metabolic and regulatory pathways were identified using MapMan software and the potential targets for candidate gene selection and ectopic expression to alter these pathways and responses are discussed.

In this study, we present the molecular cloning of porcine S100A8(pS100A8)and porcine S100A9 (pS100A9). Both genes comprise 3 exons and 2 introns and are located on pig chromosome 4q21-q23 (closely linked to SW512). Homology comparison to other mammalian species affirmed that critical functional amino acids for post-transcriptional modification, inflammatory regulation, and formation of heterodimeric complexes exist in pS100A8 and pS100A9. Under normal conditions, both genes are preferentially expressed in porcine immune or immune-related organs, e.g., bone marrow, spleen, lymph nodes, and lung. Upon stimulation in porcine whole blood cultures with LPS or Poly(I:C), they are dramatically induced. Interestingly, the maximum increase of mRNA levels in blood cultures of Meishan pigs is significantly greater than that in Duroc pigs. We previously showed that pS100A8 and pS100A9 mRNA were up-regulated following Haemophilus parasuis (HPS) infection. We herein further confirm their up-regulation at the protein level in multiple H PS infected tissues (spleen, lung and liver). Functional cluster and network analysis based on our previous microarray data discovered that CEBPB may be one of the key transcription factors. A pS100A8/pS100A9-CASP3-SLC1A2 pathway regulating lipid metabolism was found. Both of their pro-and anti-inflammatory functions in response to HPS infection are highlighted. (C) 2010 Elsevier Ltd.

TI Characteristics of small headwater wetlands in second-growth forests of Washington, USA SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE Forested wetlands; Headwaters; Logging; Down wood; Amphibians; Seep; Pacific Northwest ID STREAM TEMPERATURE RESPONSES; PACIFIC-NORTHWEST; BRITISH-COLUMBIA; COAST RANGE; MANAGEMENT; OREGON; AREAS; LANDSCAPES; BUFFERS AB In 2002, we initiated a study to clarify the response of headwater catchments to logging on timberlands in the Coast Range of Washington, USA. Most of the predominantly first-order streams studied (summer low flows typically < 0.3 Ls(-1)) were hydrologically complex, consisting of a main surface channel connected to multiple, small wetlands. To better understand the forest management implications of headwater systems with two surface hydrology components of potentially differing areal extents (i.e., broad wetlands and narrow, channelized flow), we examined in more detail the wetlands associated with 30 headwater channels. On average, 2.3 wetlands occurred per channel. All 68 surveyed wetlands were, individually, smaller than 0.1 ha, which is a minimum survey-and-manage size criterion for forested wetlands in use in the Pacific Northwest. Seventy-nine percent of the wetlands surveyed by the full-triad method met regional wetland triad criteria for wetland delineation (qualifying wetland soils, hydrology, and vegetation indicators). These headwater wetlands were associated with several landscape variables: (1) northerly-facing catchments, (2) perennial surface water, and (3) down, channel-associated large wood originating from adjacent riparian forest. Our results show that small forested wetlands are quite common and that the surface area of small wetlands can rival the surface area of the associated first-order streams. This initial effort to quantify characteristics of small headwater wetlands suggests small wetlands could dominate or influence headwater surface area processes including those associated with stream responses to disturbances such as logging.

To gain an initial understanding into the endocrine control of growth preceding and involved with sexual size dimorphism (SSD). where females have been reported to grow faster and larger than males, young of the year fish were sampled for length, weight and tissues at several time points (102-421 days post-hatch (dph)). Positive growth was seen in both sexes over the sampling interval, but SSD was not manifested. Using real-time quantitative PCR, we found that pituitary growth hormone (gh) and liver insulin-like growth factor-1b (igf1b) mRNA levels were significantly affected by dph and levels were found to be correlated with growth in both sexes. Liver cyp19a1a, esr1 and esr2a mRNA levels were significantly influenced by dph, whereas there was a significant dph * sex interaction on liver esr2a mRNA levels with males having higher levels than females at 379 and 421 dph. Ovarian cyp19a1a decreased with dph, but there were no changes in esr1 or esr2a mRNA levels. Dietary treatment of juvenile (similar to 300 dph) females with 20 mg/kg diet 17 beta-estradiol resulted in significantly higher liver esr1 mRNA levels and a sustained hepatosomatic index (I(H)). Across all data sets liver esr2a mRNA levels showed the most significant positive correlation with liver igf1b mRNA levels. These findings show that growth is accompanied by increases in pituitary gh, liver igf1b and liver esr1 and esr2a mRNAs in juvenile yellow perch. Published by Elsevier Inc.

A genome-wide linkage study using 312 microsatellites was conducted to identify loci linked with BRD in a Brahman x Hereford sire half-sib family. Disease incidence was recorded from birth to slaughter by daily monitoring. Linkage was suggestive for a QTL on BTA2 (F = 7.31, P = 0.007) and BTA26 (F = 10.46, P = 0.001). Six and 7 markers were added and genotyped between 110 and 126 cM on BTA2 and between 42 and 72 cM on BTA26, respectively, in the intervals where linkage was found. These markers were used to reevaluate the Brahman x Hereford family and to evaluate 3 additional crossbred half-sib families. Linkage was found with BRD on BTA2 (F = 4.94, P < 0.01), with a peak at 110 cM, and on BTA26 (F = 4.03, P < 0.05), with peaks at 42 and 52 cM. The same markers were then tested for an association with BVD-PI in 1) BVD-PI calves compared with age-matched unaffected calves from the same herd or 2) dams with BVD-PI compared with age-matched unaffected calves. Sixty commercial beef cow-calf herds were tested for BVD-PI, and 79 calves from 8 ranches had BVD-PI. Four of 6 markers were associated (P = 4.8 x 10(-9) to P = 0.01) with BVD-PI on BTA2, and 4 of 7 markers were associated (P = 0.008 to P = 0.04) with BVD-PI on BTA26 when BVD-PI calves were compared with unaffected calves. The comparison of BVD-PI dams with unaffected calves detected associations with BVD-PI for all markers tested on BTA2 (P = 3 x 10(-9) to P = 0.005) and for 3 of 7 markers on BTA26 (P = 1.4 x 10(-6) to P = 0.006).

The objectives of this study were to evaluate population genetic characteristics of SNP genotypes within genes of the GH-IGF axis in straightbred and crossbred Angus, Brahman, and Romosinuano heifers (n = 650) and to test the association of these genotypes with measures of reproduction. These objectives were achieved using 73 SNP within 7 genes on chromosome 5 and the pregnancy-associated plasma protein A2 (PAPP-A2) and GH-receptor genes, which map to chromosomes 16 and 20, respectively. The SNP were elucidated by resequencing conserved regions of each gene by using DNA from familial-unrelated cattle of a multibreed discovery population. A multiplex SNP assay yielded 59 biallelic SNP useful for evaluating genetic identity and distance. Specifically, the divergence of straightbred Brahman cattle was approximately 15.5% from 5 Bos taurus-influenced breed groups. In the straightbred groups used as a validation population, only 3 SNP had minor allele frequencies > 10%. These SNP were in the genes PAPP-A2 (ss115492449-A/C and ss115492450-G/T within intron 10) and signal transducers and activators of transcription 2 (STAT2; ss252841035-A/G within the 5' untranslated region), and they met the conditions of Hardy-Weinberg equilibrium (P > 0.31). The other 56 SNP were useful for assigning each animal into ancestral clusters (n = 3 proportions) to account for population stratification in genotype to phenotype association analyses. The 2 SNP in the PAPP-A2 gene influenced (P < 0.05) traits indicative of first-calf heifer rebreeding (i.e., calving interval, days to calving, and pregnancy rate). A STAT2 SNP genotype (i.e., GG) x primary ancestral cluster interaction (P < 0.05) suggested heifers primarily of B. taurus ancestry had a reduction of approximately 16.4 +/- 0.1% in calving interval and days to calving relative to heifers clustering primarily as Bos indicus ancestry. Even though additional research is needed to delineate the allelic variation attributed to genes of the GH-IGF axis, results of this study provide support for STAT2 and PAPP-A2 as potential candidate genes associated with first-calf heifer rebreeding traits.

TI Birth and weaning traits in crossbred cattle from Hereford, Angus, Brahman, Boran, Tuli, and Belgian Blue sires SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE beef cattle; breed; germplasm; gestation length; growth; survival ID FACTORS AFFECTING DYSTOCIA; REPRODUCTIVE-PERFORMANCE; PREWEANING GROWTH; BEEF-CATTLE; BIOLOGICAL TYPES; BOS-INDICUS; X ANGUS; CALVES; MYOSTATIN; BULLS AB The objective of this study was to characterize breeds representing diverse biological types for birth and weaning traits in crossbred cattle. Gestation length, calving difficulty, percentage of unassisted calving, percentage of perinatal survival, percentage of survival from birth to weaning, birth weight, BW at 200 d, and ADG were measured in 2,500 calves born and 2,395 calves weaned. Calves were obtained by mating Hereford, Angus, and MARC III (one-fourth Hereford, one-fourth Angus, one-fourth Pinzgauer, and one-fourth Red Poll) mature cows to Hereford or Angus (British breed), Brahman, Tuli, Boran, and Belgian Blue sires. Calves were born during the spring seasons of 1992, 1993, and 1994. Sire breed was significant for all traits (P < 0.002). Offspring from British breeds and the Belgian Blue breed had the shortest gestation length (285 d) when compared with progeny from other sire breeds (average of 291 d). Calving difficulty was greater in offspring from Brahman sires (1.24), whereas the offspring of Tuli sires had the least amount of calving difficulty (1.00). Offspring from all sire breeds had similar perinatal survival and survival from birth to weaning (average of 97.2 and 96.2%, respectively), with the exception of offspring from Brahman sires, which had less (92.8 and 90.4%, respectively). Progeny of Brahman sires were heaviest at birth (45.7 kg), followed by offspring from British breed, Boran, and Belgian Blue sires (average of 42.4 kg). The lightest offspring at birth were from Tuli sires (38.6 kg). Progeny derived from Brahman sires were the heaviest at 200 d (246 kg), and they grew faster (1.00 kg/d) than offspring from any other group. The progeny of British breeds and the Belgian Blue breed had an intermediate BW at 200 d (238 kg) and an intermediate ADG (average of 0.98 kg/d). The progeny of Boran and Tuli sires were the lightest at 200 d (227 kg) and had the least ADG (0.93 kg/d). Male calves had a longer gestation length, had a greater incidence of calving difficulty, had greater mortality to weaning, were heavier, and grew faster than female calves. Sire breed effects can be optimized by selection and use of appropriate crossbreeding systems. C1 [Casas, E.; Thallman, R. M.; Cundiff, L. V.] ARS, US Meat Anim Res Ctr, USDA, Clay Ctr, NE 68933 USA.

TI Differential gene expression in anterior pituitary glands from anestrous and cycling postpartum beef cows SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE anterior pituitary gland; cattle; gene expression; postpartum anestrus ID GROWTH-FACTOR-I; FACTOR-BINDING-PROTEINS; RECEPTOR-GAMMA; PEPTIDE GRP; HORMONE; SECRETION; CATTLE; ENERGY; SERUM; EWES AB Oligonucleotide microarrays (GeneChip Bovine Genome Arrays, Affymetrix Inc., Santa Clara, CA) were used to evaluate gene expression profiles in anterior pituitary glands collected from 4 anestrous and 4 cycling postpartum primiparous beef cows to provide insight into genes associated with transition from an anestrous to a cycling status. Tissues were collected 40 to 61 d after calving from anestrous cows and from cyclic cows between d 7 and 13 of the estrous cycle (luteal phase) from d 54 to 77 after calving. Hybridization signals were normalized across arrays, and genes with mean differences in expression that were at least 1.5-fold apart and with a minimum difference in mean signal intensity of 10 were compared. Based on these criteria, 47 transcripts were increased (P < 0.025) and 31 transcripts were decreased (P < 0.025) in pituitary gland tissue from cycling compared with anestrous cows. Few transcripts identified in this analysis were associated previously with reproductive function. To provide greater detail on the influence that stage of the estrous cycle (i.e., collection during the luteal phase) might have on the differences detected in gene expression, quantitative real-time PCR was used to compare gene expression in anterior pituitaries of anestrous cows with an additional independent set of anterior pituitary glands collected at 4 different stages of the estrous cycle: 0.5 to 2 d (n = 9), 5 to 6.5 d (n = 5), 11.4 to 13.7 d (n = 5), and 17.9 to 19 d (n = 6) after the onset of estrus. Gastrin-releasing peptide, the gene that exhibited the largest fold increase in expression in the microarray experiment, and IGFBP3 mRNA were expressed at greater (P < 0.004) amounts in samples from the different stages of the estrous cycle than in samples from anestrous cows. In addition, expression of IGFBP3 mRNA was proportional to serum progesterone concentrations throughout the estrous cycle (P < 0.05). Expression of versican mRNA was decreased (P = 0.03) in samples from the different stages of the estrous cycle compared with anestrous cow samples. Results identified numerous genes that may be involved in the transition from anestrous to cycling status, providing novel insight into mechanisms regulating reproductive function. C1 [Roberts, A.

TI RUMINANT NUTRITION SYMPOSIUM: Productivity, digestion, and health responses to hindgut acidosis in ruminants SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE acidosis; hindgut; ruminant ID LACTATING DAIRY-COWS; VOLATILE FATTY-ACIDS; STEAM-PROCESSED CORN; STARCH DIGESTION; PROTEIN-DEGRADATION; NUTRIENT DIGESTION; LARGE-INTESTINE; ORGANIC-MATTER; NITROGEN-EXCRETION; MILK-PRODUCTION AB Microbial fermentation of carbohydrates in the hindgut of dairy cattle is responsible for 5 to 10% of total-tract carbohydrate digestion. When dietary, animal, or environmental factors contribute to abnormal, excessive flow of fermentable carbohydrates from the small intestine, hindgut acidosis can occur. Hindgut acidosis is characterized by increased rates of production of short-chain fatty acids including lactic acid, decreased digesta pH, and damage to gut epithelium as evidenced by the appearance of mucin casts in feces. Hindgut acidosis is more likely to occur in high-producing animals fed diets with relatively greater proportions of grains and lesser proportions of forage. In these animals, ruminal acidosis and poor selective retention of fermentable carbohydrates by the rumen will increase carbohydrate flow to the hindgut. In more severe situations, hindgut acidosis is characterized by an inflammatory response; the resulting breach of the barrier between animal and digesta may contribute to laminitis and other disorders. In a research setting, effects of increased hindgut fermentation have been evaluated using pulse-dose or continuous abomasal infusions of varying amounts of fermentable carbohydrates. Continuous small-dose abomasal infusions of 1 kg/d of pectin or fructans into lactating cows resulted in decreased diet digestibility and decreased milk fat percentage without affecting fecal pH or VFA concentrations. The decreased diet digestibility likely resulted from increased bulk in the digestive tract or from increased digesta passage rate, reducing exposure of the digesta to intestinal enzymes and epithelial absorptive surfaces. The same mechanism is proposed to explain the decreased milk fat percentage because only milk concentrations of long-chain fatty acids were decreased. Pulse-dose abomasal fructan infusions (1 g/kg of BW) into steers resulted in watery feces, decreased fecal pH, and increased fecal VFA concentrations, without causing an inflammatory response. Daily 12-h abomasal infusions of a large dose of starch (similar to 4 kg/d) have also induced hindgut acidosis as indicated by decreased fecal pH and watery feces. On the farm, watery or foamy feces or presence of mucin casts in feces may indicate hindgut acidosis. In summary, hindgut acidosis occurs because of relatively high rates of large intestinal fermentation, likely due to digestive dysfunction in other parts of the gut. A better understanding of the relationship of this disorder to other animal health disorders is needed. C1 [Gressley, T. F.] Univ Delaware, Dept Anim & Food Sci, Newark, DE 19716 USA. [Hall, M.

TI Technical note: Use of near-infrared reflectance spectroscopy to predict intake and digestibility in bulls and steers SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE bull; corn silage; digestion; intake; near-infrared reflectance; steer ID DIGESTION; STRAWS; CATTLE; GRASS AB Multiple fecal samples were collected from growing Angus bulls (264 to 419 kg of BW, 3.0 to 11.4 kg/d of DMI) to predict DMI of a corn-silage-based diet. Contemporaneous digestion trials were conducted with the same diet in 12 steers in yr 1 to 3 and bulls in yr 4. Near-infrared spectra from fecal samples (n = 730 from 282 growing bulls, n = 240 from 36 steers and 12 bulls for digestion trials) were obtained from dried and ground fecal samples, and modified partial least squares regression was used to develop equations to predict DMI and DM digestibility (DMD). Although mean predicted DMI of the growing bulls (7.52 +/- 0.04 kg/d or 22.4 +/- 0.1 g/kg of BW) was within 2% of mean measured DMI (7.63 +/- 0.06 kg/d or 22.7 +/- 0.1 g/kg of BW), the mean of paired differences within samples (0.11 +/- 0.04 kg/d or 0.3 +/- 0.1 g/kg of BW) was greater (P < 0.01) than zero. Measured DMD (72.3 +/- 0.5%) was identical (P < 0.97) to predicted DMD (72.3 +/- 0.5%), and DMD for bulls in the digestion trial did not differ (P < 0.27) from DMD for steers. Prediction of intake requires incorporation of some measured values from the set of fecal samples to be predicted. Lack of similarity between spectra of fecal grab samples from the growing bulls and daily fecal collection of steers and bulls in the digestion trials in this study indicates the need for further verification before prediction of DMD with fecal grab samples.

TI Effect of quantifying peptide release on ruminal protein degradation determined using the inhibitor in vitro system SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE peptide; ruminal protein degradability; inhibitor in vitro system ID FREE AMINO-ACIDS; DAIRY-COWS; SPECTROPHOTOMETRIC ASSAY; ORTHO-PHTHALDIALDEHYDE; GRASS-SILAGE; RUMEN ESCAPE; SHEEP RUMEN; DRY-MATTER; NITROGEN; DEGRADABILITY AB The aim of this work was to compare use of an o-phthaldialdehyde (OPA) colorimetric assay (OPA-C), which responds to both free AA and peptides, with an OPA fluorimetric assay (OPA-F), which is insensitive to peptides, to quantify rates of ruminal protein degradation in the inhibitor in vitro system using Michaelis-Menten saturation kinetics. Four protein concentrates (expeller-extracted soybean meal, ESBM; 2 solvent-extracted soybean meals, SSBM1 and SSBM2; and casein) were incubated in a ruminal in vitro system treated with hydrazine and chloramphenicol to inhibit microbial uptake of protein degradation products. Proteins were weighed to give a range of N concentrations (from 0.15 to 3 mg of N/mL of inoculum) and incubated with 10 mL of ruminal inoculum and 5 mL of buffer; fermentations were stopped after 2 h by adding trichloroacetic acid (TCA). Proteins were analyzed for buffer-soluble N and buffer extracts were treated with TCA to determine N degraded at t = 0 (FD0). The TCA supernatants were analyzed for ammonia (phenol-hypochlorite assay), total AA (TAA; OPA-F), and TAA plus oligopeptides (OPA-C) by flow injection analysis. Velocity of protein degradation was computed from extent of release of 1) ammonia plus free TAA or 2) ammonia plus free TAA and peptides. Rate of degradation (k(d)) was quantified using nonlinear regression of the integrated Michaelis-Menten equation. The parameters K(m) (Michaelis constant) and k(d) (Vmax/K(m)), where Vmax = maximum velocity, were estimated directly; k(d) values were adjusted (Ak(d)) for the fraction FD0 using the equation Ak(d) = k(d) - FD0/2. The OPA-C assay yielded faster degradation rates due to the contribution of peptides to the fraction degraded (overall mean = 0.280/h by OPA-C and 0.219/h by OPA-F). Degradation rates for SSBM samples (0.231/h and 0.181/h) and ESBM (0.086/h) obtained by the OPA-C assay were more rapid than rates reported by the National Research Council (NRC). Both assays indicated that the 2 SSBM differed in rumen-undegradable protein (RUP) content; the more slowly degraded SSBM had RUP content (35% by OPA-C) similar to that reported by the NRC. The RUP content of ESBM (42% by OPA-C) was lower than the NRC value. Preliminary studies with 4 additional protein concentrates confirmed that accounting for peptide formation increased degradation rate; however, a trend for an interaction between assay and protein source suggested that peptide release made a smaller contribution to rate for more slowly degraded proteins. The OPA-C assay is a simple and reliable method to quantify formation of small peptides. C1 [Broderick, G. A.] ARS, USDA, US Dairy Forage Res Ctr, Madison, WI 53706 USA.

Seventy cows were blocked by parity and days in milk into 14 blocks and randomly assigned within blocks to 1 of the 5 dietary treatments based on alfalfa and corn silages plus high-moisture corn: 1 diet with 15.6% CP and no Met source (negative control); 3 diets with 15.6% CP plus 0.17% HMBi, 0.06% RPM + 0.10% HMB, or 0.06% RPM alone; and 1 diet with 16.8% CP and no Met supplement (positive control). Assuming that 50% of ingested HMBi was absorbed from the gastrointestinal tract and 80% of the Met in RPM was absorbed at intestine, the HMBi and RPM supplements increased metabolizable Met supply by 9 g/d and improved the Lys:Met ratio from 3.6 to 3.0. After a 2-wk covariate period during which all cows received the same diet; cows were fed test diets continuously for 12 wk. Diet did not affect dry matter intake (mean +/- SD, 25.0 +/- 0.3 kg/d), body weight gain (0.59 +/- 0.2 kg/d), or milk yield (41.7 +/- 0.6 kg/d). However, feeding HMBi increased yield of energy-corrected milk and milk content of protein and solids-not-fat. Moreover, trends were observed for increased milk fat content and yield of fat and true protein on all 3 diets containing supplemental Met. Apparent N efficiency (milk N/N intake) was highest on the RPM treatment. Feeding 16.8% CP without a Met source elevated milk urea N and urinary excretion of urea N and total N and reduced apparent N efficiency from 34.5 to 30.2%, without improving production. Overall results suggested that feeding HMBi or RPM would give similar improvements in milk production and N utilization. C1 [Broderick, G.

The objectives of this study were to analyze trends in atrazine concentration and load in Goodwater Creek Experimental Watershed (GCEW) from 1992 to 2006, and to conduct a retrospective assessment of the potential aquatic ecosystem impacts caused by atrazine contamination. Located within the Central Claypan Region of northeastern Missouri, GCEW encompasses 72.5 km2 of predominantly agricultural land uses, with an average of 21% of the watershed in corn and sorghum. Flow-weighted runoff and weekly base-flow grab samples were collected at the outlet to GCEW and analyzed for atrazine. Cumulative frequency diagrams and linear regression analyses generally showed no significant time trends for atrazine concentration or load. Relative annual loads varied from 0.56 to 14% of the applied atrazine, with a median of 5.9%. A cumulative vulnerability index, which takes into account the interactions between herbicide application, surface runoff events, and atrazine dissipation kinetics, explained 63% of the variation in annual atrazine loads. Based on criteria established by the U.S. Environmental Protection Agency, atrazine reached concentrations considered harmful to aquatic ecosystems in 10 of 15 years.

The main objective of this study was to analyze trends in concentration and load of acetochlor, alachlor, metolachlor, and metribuzin in Goodwater Creek Experimental Watershed (GCEW) from 1992 to 2006. A secondary objective was to document the effects of best management practices (BMPs) implemented within GCEW on herbicide transport trends. Median relative herbicide loads, as a percent of applied, were 3.7% for metolachlor, 1.3% for metribuzin, 0.36% for acetochlor, and 0.18% for alachlor. The major decrease in alachlor use and increase in acetochlor use caused shifts in flow-weighted concentrations that were observed over the entire concentration range. The smaller decrease in metolachlor use led to a consistent decreasing time trend only for the upper end of the concentration distribution. Metribuzin also showed moderate decreases in concentration with time since 1998. Annual loads were generally correlated to second quarter discharge. Despite extensive education efforts in the watershed, conservation BMPs within GCEW were mainly implemented to control erosion, and therefore had no discernable impact on reducing herbicide transport. Overall, changes in herbicide use and second quarter discharge had the greatest effect on trends in flow-weighted concentration and annual load. C1 [Lerch, R. N.; Sadler, E.

For this purpose, this study investigates a model association based on the Soil and Water Assessment Tool (SWAT) coupled with a hydrodynamic model (MARS 2D; IFREMER). Application was performed on the catchment and estuary of Daoulas area (France). The daily E. coli fluxes simulated by SWAT are taken as an input in the MARS 2D model to calculate E. coli concentrations in estuarine water and shellfish. Model validation is based on comparison of frequencies: a strong relationship was found between calculated and measured E. coli concentrations for river quality (r2 = 0.99) and shellfish quality (r2 = 0.89). The important influence of agricultural practices and rainfall events on the rapid and large fluctuations in E. coli fluxes from the watershed (reaching three orders of magnitude in < 24 hours) is one main result of the study. Response time in terms of seawater quality degradation ranges from one to two days after any important rainfall event (greater than 10 mm/day) and the time for estuary to recover good water quality also mainly depends on the duration of the rainfall. In the estuary, three effects (rainfall, tidal dilution, and manure spreading) have been identified as important influences. C1 [Bougeard, Morgane] IDHESA, F-29280 Plouzane, France.

Diploid eggs can develop either into queens, which specialize in reproduction, or workers, which participate in cooperative tasks such as building the nest, collecting food, and rearing the young. In contrast, the differentiation between males and females generally depends upon whether eggs are fertilized, with fertilized (diploid) eggs giving rise to females and unfertilized (haploid) eggs giving rise to males. To obtain a comprehensive picture of the relative contributions of gender (sex), caste, developmental stage, and species divergence to gene expression evolution, we investigated gene expression patterns in pupal and adult queens, workers, and males of two species of fire ants, Solenopsis invicta and S. richteri. Microarray hybridizations revealed that variation in gene expression profiles is influenced more by developmental stage than by caste membership, sex, or species identity. The second major contributor to variation in gene expression was the combination of sex and caste. Although workers and queens share equivalent diploid nuclear genomes, they have highly distinctive patterns of gene expression in both the pupal and the adult stages, as might be expected given their extraordinary level of phenotypic differentiation. Overall, the difference in the proportion of differentially expressed genes was greater between workers and males than between workers and queens or queens and males, consistent with the fact that workers and males share neither gender nor reproductive capability. Moreover, between-species comparisons revealed that the greatest difference in gene expression patterns occurred in adult workers, a finding consistent with the fact that adult workers most directly experience the distinct external environments characterizing the different habitats occupied by the two species. Thus, much of the evolution of gene expression in ants may occur in the worker caste, despite the fact that these individuals are largely or completely sterile. Analyses of gene expression evolution revealed a combination of positive selection and relaxation of stabilizing selection as important factors driving the evolution of such genes.

Association mapping in contemporary breeding germplasm may lead to more effective marker strategies for crop improvement. To test this approach, we conducted association mapping of two complex traits with moderate heritability; Fusarium head blight (FHB) severity and the grain concentration of mycotoxin associated with disease, deoxynivalenol (DON). To map FHB resistance in barley, 768 breeding lines were evaluated in 2006 and 2007 in four locations. All lines were genotyped with 1,536 SNP markers and QTL were mapped using a mixed model that accounts for relatedness among lines. Average linkage disequilibrium within the breeding germplasm extended beyond 4 cM. Four QTL were identified for FHB severity and eight QTL were identified for the DON concentration in two independent sets of breeding lines. The QTL effects were small, explaining 1-3% of the phenotypic variation, as might be expected for complex polygenic traits. We show that using breeding germplasm to map QTL can complement bi-parental mapping studies by providing independent validation, mapping QTL with more precision, resolving questions of linkage and pleiotropy, and identifying genetic markers that can be applied immediately in crop improvement.

The selection of resistant germplasm has great potential to reduce the problem, but the highly quantitative nature of the trait makes this a difficult endeavor. The identification of aflatoxin accumulation resistance quantitative trait loci (QTL) from resistant donor lines and the discovery of linked markers could speed this task. To identify marker-trait associations for marker-assisted breeding, a genetic mapping population of F-2:3 families was developed from Mp715, a maize inbred line resistant to aflatoxin accumulation, and T173, a susceptible, southern-adapted maize inbred line. QTL, some with large phenotypic effects, were identified in multiple years on chromosomes 1, 3, 5, and 10, and smaller QTL identified in only 1 year were found on chromosomes 4 and 9. The phenotypic effect of each QTL ranged from 2.7 to 18.5%, and models created with multiple QTL could explain up to 45.7% of the phenotypic variation across years, indicating that the variation associated with the trait can be manipulated using molecular markers.

To characterize quantitative trait loci (QTLs) for PHS resistance and seed dormancy (SD), we evaluated 162 recombinant inbred lines developed from the cross between PHS-resistant white wheat landrace Tutoumai A and PHS-susceptible white wheat cultivar 'Siyang 936' for PHS resistance and SD in field and greenhouse experiments. Composite interval mapping (CIM) identified four QTLs for PHS resistance and long SD that explained up to 45 and 40.8% of the phenotypic variation in five PHS and four SD experiments, respectively. Qphs.pseru-4A.1 was detected in three of the five PHS experiments, and Qphs.pseru-5B.1, Qphs.pseru-5B.2, and Qphs.pseru-4B.1 were detected in two of the five PHS experiments, respectively. All four QTLs for PHS resistance also affected SD. Qphs.pseru-4A.1 was significant in all four SD experiments; the other three QTLs were detected only in one experiment. Additive and epistatic effects were observed for PHS resistance and SD. Besides three additive QTLs for PHS resistance and two for long SD, an additional 11 and 10 QTLs were detected with epistatic effects on PHS resistance and SD, respectively. The major genetic component of PHS resistance was SD, and other genetic factors may also contribute to PHS resistance in this population.

In both progenies, the red skin color phenotype was usually associated with the MdMYB1-1 allele. This dCAPS marker provided approximately 80% predictability in a 'Golden Delicious' x 'Arlet' and a 'Honeycrisp' x 'Cripps Pink' progeny. Other potential genetic co-regulators may explain the less-than-perfect association. The specific dCAPS bands associated with red skin for the latter population were not the same as those identified in the former population or those reported in previous studies, indicating that skin color genotyping based on this marker will require prior association between specific marker alleles and color phenotypes for any given cross. The current form of this marker could be a useful tool for apple marker-assisted breeding, particularly in breeding programs in which 'Golden Delicious' is a parent.

However, this will depend on the spatial scale over which individuals compete. Here, we quantify this scale for juvenile Atlantic salmon (Salmo salar) following emergence and dispersal from nests. A single nest was placed in each of ten replicate streams during winter, and information on the individual positions (+/- 1 m) and the body sizes of the resulting young-of-the-year (YOY) juveniles was obtained by sampling during the summer. In six of the ten streams, model comparisons suggested that individual body size was most closely related to the density within a mean distance of 11 m (range 2-26 m). A link between body size and density on such a restricted spatial scale suggests that dispersal from nests confers energetic benefits that can counterbalance any survival costs. For the four remaining streams, which had a high abundance of trout and older salmon cohorts, no single spatial scale could best describe the relation between YOY density and body size. Energetic benefits of dispersal associated with reduced local density therefore appear to depend on the abundance of competing cohorts or species, which have spatial distributions that are less predictable in terms of distance from nests. Thus, given a trade-off between costs and benefits associated with dispersal, and variation in benefits among environments, we predict an evolving and/or phenotypically plastic growth rate threshold which determines when an individual decides to disperse from areas of high local density.

A total of 25 piglets weighing between 2 and 12 kg were studied. Body composition was assessed by QMR, dual-energy x-ray absorptiometry (DXA), and whole-body chemical analysis (CA) of carcass for lipid and water content. The precision, mean and SD of repeated measurements, of QMR to estimate fat mass (FM), lean mass (LM), and total body water (TBW) for five consecutive scans with reposition was 12.5, 32.0, and 36.0 g, respectively. QMR measures of FM, LM, and TBW were highly and significantly correlated with CA of carcass. In terms of accuracy, mean difference between QMR and CA (percent of mean value for CA), QMR overestimated FM by 40 g (4.7%), overestimated LM by 114.9 g (2.1%), and underestimated TBW by 134.6 g (3.1%). This study concludes that QMR provides precise and accurate measures of FM, LM, and TBW in piglet weighing up to 12 kg. These results suggest that QMR can provide valuable body composition data in longitudinal studies in infants.

TI Rate of Phenylalanine Hydroxylation in Healthy School-Aged Children SO PEDIATRIC RESEARCH LA English DT Article ID AMINO-ACID OXIDATION; PARENTERAL-NUTRITION; TYROSINE KINETICS; YOUNG MEN; LYSINE REQUIREMENT; ORAL TRACER; INDICATOR; PROTEIN; HUMANS; CONVERSION AB Hydroxylation of phenylalanine to tyrosine is the first and rate-limiting step in phenylalanine catabolism. Currently, there are data on the rate of phenylalanine hydroxylation in infants and adults but not in healthy children. Thus, the aim of the study reported here was to measure the rate of phenylalanine hydroxylation and oxidation in healthy school-aged children both when receiving diets with and without tyrosine. In addition, hydroxylation rates calculated from the isotopic enrichments of amino acids in plasma and in very LDL apoB-100 were compared. Eight healthy 6- to 10-y-old children were studied while receiving a control and again while receiving a tyrosine-free diet. Phenylalanine flux, hydroxylation, and oxidation were determined by a standard tracer protocol using oral administration of (13)C-phenylalanine and (2)H(2)-tyrosine for 6 h. Phenylalanine hydroxylation rate of children fed a diet devoid of tyrosine was greater than that of children fed a diet containing tyrosine (40.25 +/- 5.48 versus 29.55 +/- 5.35 mu mol . kg(-1) . h(-1); p < 0.01). Phenylalanine oxidation was not different from phenylalanine hydroxylation regardless of dietary tyrosine intake, suggesting that phenylalanine converted to tyrosine was mainly oxidized. In conclusion, healthy children are capable of converting phenylalanine to tyrosine, but the need for tyrosine cannot be met by providing extra phenylalanine.

TI Efficacy of layer treatment with methoprene for control of Rhyzopertha dominica (Coleoptera: Bostrychidae) on wheat, rice and maize SO PEST MANAGEMENT SCIENCE LA English DT Article DE grain protectants; insect growth regulator; methoprene; Rhyzopertha dominica; stored-product insects ID INSECT GROWTH-REGULATORS; F COLEOPTERA; DIATOMACEOUS-EARTH; SITOPHILUS-ORYZAE; CHLORPYRIFOS-METHYL; PLUS METHOPRENE; STORED-GRAIN; BOSTRICHIDAE; RESISTANCE; SPINOSAD AB BACKGROUND: Insect growth regulators are promising alternatives to traditional pesticides in stored grain. The efficacy of the juvenile hormone analogue methoprene was evaluated as a layer treatment in a laboratory experiment for control of Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae) in wheat, rice and maize. RESULTS: Adults of R. dominica were placed in vials containing 33, 26 and 29 g (to a depth of 6.5 cm) of wheat, rice and maize, respectively, that was entirely or partially treated with 1, 5 or 10mg kg(-1) methoprene. In wheat and rice, the layer treatments were not as effective as the whole-grain treatment, but there was decreased progeny production as the application rate increased. However, onmaize the partial treatmentswere as effective as the whole-grain treatment at 5 and 10 mg kg(-1). CONCLUSIONS: The results suggest that partial layer treatments with methoprene can be used to control R. dominica on maize butmay not be effective for control of this species on wheat and rice.

This study was conducted to elucidate the action mechanisms of pymetrozine on the feeding behaviour of the planthopper. RESULTS: The activity test showed that pymetrozine primarily functioned as an antifeedant that caused starvation and death in N. lugens, rather than having neurotoxicity. Pymetrozine-treated insects died at a significantly slower speed than insects treated with starvation. Electrical penetration graph (EPG) data indicated that pymetrozine significantly increased the duration of non-probing periods and had a strong inhibition to phloem ingestion. The inhibition was strongly dose dependent, resulting in a complete suppression of the activity in the phloem region when the pymetrozine concentration was increased to 400 mg L(-1). Starvation caused by inhibition of phloem ingestion might be a major toxicity mechanism of pymetrozine. EPG data also showed that pymetrozine had no significant effect on stylet movement and duration of xylem sap ingestion. CONCLUSION: The study revealed that pymetrozine disturbed the feeding behaviour of N. lugens mainly by increasing the non-probe period and inhibiting phloem ingestion. The inhibition resulted in a slow death similar to starvation.

TI Kinetics of zinc release from ground tire rubber and rubber ash in a calcareous soil as alternatives to Zn fertilizers SO PLANT AND SOIL LA English DT Article DE Waste tire rubber; Calcareous soil; Zn fertilizer; Release kinetics ID DESORPTION; GROWTH; MEDIA AB Ground rubber contains 15-20 g Zn kg(-1) but very low levels of Cd and could serve as an inexpensive byproduct Zn fertilizer. The aim of this investigation was to test Zn release in a soil treated with ground tire rubber and rubber ash compared with commercial Zn fertilizer and a laboratory grade zinc sulfate. A Zn-deficient soil was chosen from wheat fields in Isfahan province, central Iran, and the ground rubber, rubber ash and fertilizer-Zn and laboratory ZnSO(4) were added at 0.5 and 2 mg Zn kg(-1); 0.5 kg ha(-1) would usually correct Zn deficiency in such pot tests. The soil DTPA-extractable Zn was then measured with time and the results were described examining first order, Elovich, power function and parabolic diffusion kinetics models. In the pot experiment, corn (Zea mays L.) plants were exposed to three rates of Zn (0, 20, 40 mg Zn kg(-1)) from two different sources (ZnSO(4) and ground rubber). Ground rubber was applied as 2-3 mm and < 1 mm diameter particles. Zinc treatments were mixed with the soils before planting. At harvest, concentrations of Zn, Pb, and Cd in roots and shoots of corn were measured. Results showed that ground rubber and rubber ash significantly increased the concentration of DTPA-Zn in the soil and this increase was higher than achieved with the commercial Zn fertilizer. At the lower Zn application rate, Zn release followed parabolic diffusion, while at the higher rate the kinetics of release followed power function and Elovich models. There was an increase in Zn concentration of corn shoot and roots by adding of Zn regardless the source of applied Zn. With increase in the rate of rubber used, the shoot Zn uptake increased. The Pb concentration of shoot and Cd concentrations of shoot and roots were low (less than 0.02 mg kg(-1)) in all treatments. The results showed that the soil DTPA Zn decreases over time if the soil is amended with a soluble form of Zn whereas the reverse was observed if the Zn is added as ground rubber which only gradually transforms. Thus ground rubber and rubber ash offer strong value as Zn fertilizer for Zn deficient soils.

Sinigrin was the major glucosinolate in LM, WSM and DSM, occurring at concentration of 0.11, 12.2 and 21.9 mg/gdw, respectively. Allyl isothiocyanate (AITC) was the major degradation product and its concentration was highest in DSM followed by WSM and LM. The number of galls, egg masses and eggs on tomato plants was reduced by over 90% by amending soil with 1.6% LM, 0.2% WSM, or 0.05% DSM. Exposure to the volatiles from the amended soils reduced egg eclosion. The soil amendment with LM, WSM and DSM killed the second stage juveniles of M. javanica, M. enterolobii (=M. mayaguensis) and Heterodera glycines. The efficacy of the LM, WSM and DSM for nematode suppression was related to the amount of AITC released in soil. C1 [Oliveira, Rosangela D.

SO PLANT AND SOIL LA English DT Article DE Bromus tectorum; Fire; Nitrogen; Ammonium nitrate; 15N ID GREAT-BASIN; SAGEBRUSH-STEPPE; NUTRIENT BUDGETS; FOREST; ECOSYSTEM; DYNAMICS; INVASION; WILDFIRE; USA AB Cheatgrass (Bromus tectorum L.), an invasive annual grass, is displacing native species and causing increased fire frequency in the Great Basin of the southwestern United States. Growth and nitrogen uptake patterns by cheatgrass were examined in a greenhouse study using soils from sites with the same soil type but different fire histories: 1) an area that burned in 1999 that is now completely invaded with cheatgrass (CG); 2) an area that has not burned recently and is now dominated by Wyoming big sagebrush (Artemisia tridentatassp.wyomingensis Beetle and Young) and Sandberg's bluegrass (Poa secunda J. Presl) (WBS); and 3) a Wyoming big sagebrush area that burned in August of 2008 just prior to soil collection (NB). Cheatgrass seedlings had higher leaf numbers, height and mass in the NB soil. Ammonium-N mobilized by fire in the NB soil had significantly enriched (15)N than soils from CG or WBS sites and this pattern was reflected in the isotopic signatures of the plants. Fire-mobilized mineral N accounted for only 58% of N taken up by cheatgrass in the NB soil, suggesting fire enhanced the ability of cheatgrass to assimilate more recalcitrant soil organic N.

In this study, the sequence of a prophage terminase gene of 'Candidatus Liberibacter asiaticus', a bacterium associated with citrus Huanglongbing (HLB), was selected as a molecular marker to assess the genetic variation in two 'Ca. L. asiaticus' populations from geographically distinct provinces (Guangdong and Yunnan) in China. The frequency of the prophage terminase gene was 15.8% (19/120) in Guangdong (altitude < 500 m) and 97.4% (38/39) in Yunnan (altitude > 2,000 m). The difference was highly significant (P < 0.0001) based on chi(2) analysis. However, the partial prophage terminase gene sequences obtained from 10 Guangdong strains and 6 Yunnan strains were identical or highly similar, suggesting that at least some bacterial strains in the two locations shared a common recent origin. This is the first report on population variation of 'Ca. L. asiaticus' in China, where HLB was first described. The population variation of 'Ca. L. asiaticus' in the two geographical regions and the related HLB epidemiology were discussed.

TI Analysis of Induction and Establishment of Dwarf Bunt of Wheat Under Marginal Climatic Conditions SO PLANT DISEASE LA English DT Article ID DIFENOCONAZOLE SEED TREATMENT; WINTER-WHEAT AB Dwarf bunt caused by Tilletia contraversa is a disease of winter wheat that has a limited geographic distribution due to specific winter climate requirements. The pathogen is listed as a quarantine organism by several countries that may have wheat production areas with inadequate or marginal climate for the disease-in particular the People's Republic of China. Field experiments were conducted in the United States in an area of Kansas that is a climatic analog to the northern winter wheat areas of China to evaluate the risk of disease introduction into such areas. The soil surface of four replicate 2.8 x 9.75 m plots, planted with a highly susceptible cultivar, was inoculated with six teliospore concentrations ranging from 0.88 to 88,400 teliospores/cm(2). A single initial inoculation was done in each of three nurseries planted during separate seasons followed by examination for disease for 4 to 6 years afterward. Any diseased spikes produced were crushed and returned to the plots where they were produced. One nursery had no disease during all six seasons. In two nurseries, the disease was induced at trace levels at the three highest inoculation rates. Disease carryover to the second year occurred during one year in one nursery in plots at the highest inoculation rate, but no disease occurred the following three seasons. A duplicate nursery planted in a disease conducive area in Utah demonstrated that the highest rate of inoculum used in the experiments was sufficient to cause almost 100% infection. This study demonstrated that in an area with marginal climatic conditions it was possible to induce transient trace levels of dwarf bunt, but the disease was not established even with a highly susceptible cultivar and high levels of inoculum. Our results support the conclusions of the 1999 Agreement on U.S.-China Agricultural Cooperation which set a tolerance for teliospores in grain, and supports the Risk Assessment Model for Importation of United States Milling Wheat Containing T contraversa.

Appropriate restoration techniques require an understanding of the degree to which intra and interspecific competition control invasive and native plant growth. The objective of this study was to determine how the intensity of intra and interspecific competition changes during early stages of plant growth. Two invasive (Bromus tectorum and Taeniatherum caput-medusae) and two native (Pseudoroegneria spicata and Poa secunda) species were grown in a diallel competition experiment, either alone or in 1:1 binary combinations and exposed to two levels of N (no N or 400 mg N kg(-1) soil added) in a greenhouse. Total biomass for each species was quantified over four harvests and competitive effects were calculated. Our results show that the relative magnitude of intra and interspecific competition changes through time. Intraspecific competition was intense for native species at the initial harvests and therefore important in contributing to the outcome of final size of native species seedlings. Interestingly, bluebunch wheatgrass imposed interspecific competition on annual grasses at the first two harvests and appeared to be a better competitor than Sandberg's bluegrass. We found that fast growing invasive species became more competitive compared to slow growing native species with increasing N and appear to establish a positive feedback mechanism between size and resource uptake. Opportunities to improve restoration success exist from determining the optimum combination of density, species proportion, and their spatial arrangement in various ecosystems and environments.

Across the superfamily there is only limited sequence similarity, but a series of highly conserved motifs, including the AMP-binding domain, make it easy to identify members. These conserved motifs are best understood in terms of the unique domain-rotation architecture that allows AAE enzymes to catalyze the two distinct steps of the CoA ligase reaction. Arabidopsis AAE sequences were used to identify the AAE gene families in the sequenced genomes of green algae, mosses, and trees; the size of the respective families increased with increasing degree of organismal cellular complexity, size, and generation time. Large-scale genome duplications and small-scale tandem gene duplications have contributed to AAE gene family complexity to differing extents in each of the multicellular species analyzed. Gene duplication and evolution of novel functions in Arabidopsis appears to have occurred rapidly, because acquisition of new substrate specificity is relatively easy in this class of proteins. Convergent evolution has also occurred between members of distantly related clades. These features of the AAE superfamily make it difficult to use homology searches and other genomics tools to predict enzyme function.

The crosslinking reaction was carried out in either acetic acid or ethanolic HCl where the amount of crosslinking reagent was between 1 and 6%. Reactions were carried out at various times and temperatures. When carried out in acetic acid, the maximum amount of formaldehyde that could be used was 1.5% as gelation occurred at higher levels. In ethanolic HCl, 6% formaldehyde could be incorporated into zein. All solutions were successfully electrospun, producing predominantly ribbon and round fibers; the morphology was strongly dependent on solvent and spinning solids. The formaldehyde-crosslinked zein fabrics had double the tensile strength of control fabrics. SDS-PAGE analysis clearly showed crosslinking had occurred. Electrospun fabrics from all formaldehyde-treated zein solutions required an additional heating step in order to be resistant to dissolution in acetic acid, a known very good solvent for zein.

TI Selective chemical oxidation and depolymerization of (Panicum virgatum L.) xylan with switchgrass oligosaccharide product analysis by mass spectrometry SO RAPID COMMUNICATIONS IN MASS SPECTROMETRY LA English DT Article ID TEMPO-MEDIATED OXIDATION; CELL-WALL; STRUCTURAL-CHARACTERIZATION; COMPARATIVE GLYCOMICS; CORN STOVER; WATER; ACID; ARABINOXYLANS; FLOUR; DIFFERENTIATION AB Xylan is a barrier to enzymatic hydrolysis of plant cell walls. It is well accepted that the xylan layer needs to be removed to efficiently hydrolyze cellulose; consequently, pretreatment conditions are (in part) optimized for maximal xylan depolymerization or displacement. Xylan consists of a long chain of beta-1,4-linked xylose units substituted with arabinose (typically alpha-1,3-linked in grasses) and glucuronic acid (alpha-1,2-linked). Xylan has been proposed to have a structural function in plants and therefore may play a role in determining biomass reactivity to pretreatment. It has been proposed that substitutions along xylan chains are not random and, based upon studies of pericarp xylan, are organized in domains that have specific structural functions. Analysis of intact xylan is problematic because of its chain length (> degree of polymerization (d.p.) 100) and heterogeneous side groups. Traditionally, enzymatic end-point products have been characterized due to the limited products generated. Analysis of resultant arabino-xylo-oligosaccharides by mass spectrometry is complicated by the isobaric pentose sugars that primarily compose xylan. In this report, the variation in pentose ring structures was exploited for selective oxidation of the arabinofuranose primary alcohols followed by acid depolymerization to provide oligosaccharides with modified arabinose branches intact. Switchgrass samples were analyzed by hydrophilic interaction chromatography (HILIC)-liquid chromatography (LC)-mass spectrometry/mass spectrometry (MSMS) and off-line nanospray MS to demonstrate the utility of this chemistry for determination of primary hydroxyl groups on oligosaccharide structures, with potential applications for determining the sequence of arabino-xylo-oligosaccharides present in plant cell wall material.

A prerequisite for investigation of individual Eimeria species is to isolate a single oocyst from fecal samples. A novel method for isolating a single Eimeria oocyst from poultry litter using a micromanipulator was developed. This simple method is fast and reliable, and provides direct isolation of a single sporulated oocyst from fecal samples harboring multiple Eimeria species or samples contaminated by other species of parasite.

These agencies generally have regulatory authority over the production and retail sectors of the farm-to-table continuum. Any predicted change in contamination that results from new policy that regulates production practices occurs many steps prior to consumption of the product. This study proposes a framework for conducting microbial food-safety risk assessments; this framework can be used to quantitatively assess the annual effects of national regulatory policies. Advantages of the framework are that estimates of human illnesses are consistent with national disease surveillance data (which are usually summarized on an annual basis) and some of the modeling steps that occur between production and consumption can be collapsed or eliminated. The framework leads to probabilistic models that include uncertainty and variability in critical input parameters; these models can be solved using a number of different Bayesian methods. The Bayesian synthesis method performs well for this application and generates posterior distributions of parameters that are relevant to assessing the effect of implementing a new policy. An example, based on Campylobacter and chicken, estimates the annual number of illnesses avoided by a hypothetical policy; this output could be used to assess the economic benefits of a new policy. Empirical validation of the policy effect is also examined by estimating the annual change in the numbers of illnesses observed via disease surveillance systems.

Both approaches indicated a carbon sink over this heterogeneous region in 2003 (a relatively warm, dry year in western Oregon) and 2007 (near normal), with carbon uptake primarily in forested and agricultural areas. The statewide mean NEP for 2007 using the bottom-up approach was 80 gC m-2 yr-1, which compares with 145 gC m-2 yr-1 for the top-down approach. Seasonality of daily NEP at the ecoregion scale showed similar patterns across the two approaches, but with less sensitivity to seasonal drought in the top-down model. In 2003, simulated annual NEP was lower than in 2007 for both scaling approaches, but the reduction was stronger with the bottom-up approach. Estimates of mean NEP on forested lands from a forest inventory approach, and from the CarbonTracker inversion scheme, bracketed that of our bottom-up approach (ratios to bottom-up estimates were 1.3 and 0.3, respectively). These results support the need for a multiple constraint approach to evaluation of regional trace gas budgets. C1 [Turner, D. P.; Goeckede, M.; Law, B. E.; Ritts, W.

Although it is generally accepted that these subdomains differ in their protein and perhaps lipid compositions, a clear understanding of how they are assembled and maintained has not been well established. We previously demonstrated that two diacylglycerol acyltransferase enzymes (DGAT1 and DGAT2) from tung tree (Vernicia fordii) were located in different subdomains of ER, but the mechanisms responsible for protein targeting to these subdomains were not elucidated. Here we extend these studies by describing two glycerol-3-phosphate acyltransferase-like (GPAT) enzymes from tung tree, GPAT8 and GPAT9, that both colocalize with DGAT2 in the same ER subdomains. Measurement of protein-protein interactions using the split-ubiquitin assay revealed that GPAT8 interacts with itself, GPAT9 and DGAT2, but not with DGAT1. Furthermore, mutational analysis of GPAT8 revealed that the protein's first predicted hydrophobic region, which contains an amphipathic helix-like motif, is required for interaction with DGAT2 and for DGAT2-dependent colocalization in ER subdomains. Taken together, these results suggest that the regulation and organization of ER subdomains is mediated at least in part by higher-ordered, hydrophobic-domain-dependent homo- and hetero-oligomeric protein-protein interactions.

This observation prompted investigations on the biological control efficacy of MV on various Ipomoea species under a controlled environment. Seven morningglory species [ivyleaf (lpomoea hederacea), moonvine (lpomoea turbinate), palmleaf (Ipoinoea wrightii), pitted (Ipomoea lacunoso), multi-color (Ipomoea tricolor), moonflower (Ipomoea alba), and cypressvine (Ipomoea quamoclit)] were grown in greenhouse and tested at first to second leaf growth stage. MV spores (102spores mU 1) were formulated in Silwet L-77 surfactant (0.2 To, v/v) or an invert emulsion containing this surfactant. Plants were treated either with Silwet (0.2%, v/v) alone (control), invert emulsion plus Silwet, MV plus Silwet, or MV plus Silwet plus invert emulsion via spray application. After application, the plants were placed in a dew chamber (15-18 h) and then transferred to a greenhouse. Plant injury and disease progression were assessed visually and fresh and dry weights were determined at the end of tests (7 days after treatment). Some of these species exhibited more tolerance than others to spray applications of MV plus Silwet, depending on the time after treatment. Compared to MV alone treatments, formulations of MV plus the invert emulsion promoted injury symptomology in pitted and moonvine morning-glories, but caused less disease symptomology than MV alone in palmleaf seedlings. There were no significant differences in disease symptomology of the MV alone and MV plus invert treatments in the other species. Overall, the results indicate some differential injury effects of MV on closely related species, i.e., Ipomoea (morning-glories), and that the invert emulsion can increase the efficacy of MV in certain instances.

TI Hairy vetch (Vicia villosa) seed size affects germination response to coumarin SO ALLELOPATHY JOURNAL LA English DT Article DE Allelochemical; germination inhibition; hairy vetch; seed size; seed weight; small seed sensitivity; Vicia villosa ID GROWTH; WEED AB The inhibition of seed germination by an allelochemical is generally greater in small seeds than in large seeds. This response may have significant impact on weed control by allelopathic cover crops, where the small-seeded weeds would be more effectively controlled than large-seeded species. The studies reporting these results used a large number of plant species that varied in seed size, which might have introduced differences in germination characteristics or various parameters required for growth and emergence. One approach to avoid factors associated with the use of a mixed seed size population is to separate a large population of seeds from a single species into various size classes. This allows the analysis of the effects of a given allelochemical directly as a function of seed size. Here, hairy vetch (Vida villosa Roth.) seeds were separated into three classes based on their seed weight (large, 54 mg; medium, 40 mg; and small, 26 mg) and compared their germination response to coumarin at 10(-3) and 10(-5) M. There was no significant difference in germination to 10(-5) M coumarin with respect to seed size. However, germination was reduced and delayed in seeds exposed to 10-3M coumarin, and this effect was more noticeable in the small seed class. Expressed as a percent of control, germination for large, medium and small seeds was 72, 76, and 55% respectively and germination of small seeds was also delayed by two days. These results confirm that small seeds are more sensitive to an allelochemical and this sensitivity is selective within a species with respect to small versus large seed. If expressed by a cover crop, this selection pressure could have significant impact on the weed community over time. C1 [Williams, R. D.; Bartholomew, P.

Efficacy varied by rodenticide tested and rodent species. Generally, rodenticides were more effective against mice than for either of the rat species, and mice tended to consume more rodenticide bait than the laboratory chow alternative food. Efficacy was generally highest for the second-generation anticoagulants tested; however, this varied across products and one-first-generation rodenticide had similar effectiveness. Bait acceptance (palatability) also varied both by rodenticide and by rodent species. Acceptance was the lowest for the acute rodenticides. Bait acceptance appeared to substantially affect the efficacy of rodenticides; materials that were not well accepted produced lower mortality rates. Rodenticide products currently registered for use in Hawaii performed less effectively in this study than other available products not yet registered. Although markets for rodent control products for use on islands are limited, there are advantages to having additional products registered for island use in agriculture, conservation, and public health.

These studies document physiologically directed reallocations of immune costs to other high-cost areas of physiology. Immunosenescence, recognized as the age-related deterioration of immune functions, is another mechanism of radically altering immune systems. We investigated the hypothesis that aging brings on immunosenescence in adult males of the cricket, Gryllus assimilis. Our data show that the intensity of melanotic nodule formation decreased with adult age from after 3-week post-adult emergence. Circulating hemocyte populations similarly decreased from about 5,000 hemocytes/mu l hemolymph to about 1,000 hemocytes/mu l hemolymph. The numbers of damaged hemocytes in circulation increased from less than 10% at 1-week post-adult emergence to approximately 60% by 3-week post-adult emergence. The composition of hemocyte types changed with age, with increasing proportions of granulocytes and decreasing proportions of plasmatocytes. The declines in nodule formation were not linked to the adult age of sexual behaviors, which begin shortly after entering adulthood in this species. We infer that age-related senescence, rather than cost reallocations, may account for observed declines in various parameters of immune functions in insects, as seen in other animals.

The 45 proteins share the conserved beta-barrel and plug domains of TonB-dependent proteins but only 18 of them have an N-terminal signaling domain characteristic of TonB-dependent transducers (TBDTs), which participate in cell-surface signaling systems. Phylogenetic analyses of the 18 TBDTs and 27 TonB-dependent receptors (TBDRs), which lack the N-terminal signaling domain, suggest a complex evolutionary history including horizontal transfer among different microbial lineages. Putative functions were assigned to certain TBDRs and TBDTs in clades including well-characterized orthologs from other Pseudomonas spp. A mutant of Pf-5 with deletions in pyoverdine and enantio-pyochelin biosynthesis genes was constructed and characterized for iron-limited growth and utilization of a spectrum of siderophores. The mutant could utilize as iron sources a large number of pyoverdines with diverse structures as well as ferric citrate, heme, and the siderophores ferrichrome, ferrioxamine B, enterobactin, and aerobactin. The diversity and complexity of the TBDTs and TBDRs with roles in iron uptake clearly indicate the importance of iron in the fitness and survival of Pf-5 in the environment.

Studies over the last year have highlighted more and more polymorphisms, pathways and interactions responsible for metabolic disorders such as cardiovascular disease, obesity and dyslipidemia. Recent findings Many of these chronic illnesses can be partially blamed by altered lipid metabolism, combined with individual genetic components. Critical evaluation and comparison of these recent studies is essential in order to comprehend the results, conclusions and future prospects in the field of genomics as a whole. Recent literature elucidates significant gene-diet and gene-environment interactions resulting in altered lipid metabolism, inflammation and other metabolic imbalances leading to cardiovascular disease and obesity. Summary Epigenetic and epistatic interactions are now becoming more significantly associated with such disorders, as genomic research digs deeper into the complex nature of genetic individuality and heritability. The vast array of data collected from genome-wide association studies must now be empowered and explored through more complex interaction studies, using standardized methods and larger sample sizes. In doing so the etiology of chronic disease progression will be further understood. C1 [Ordovas, Jose M.] Tufts Univ, Nutr & Genom Lab, Jean Mayer USDA HNRCA, Boston, MA 02111 USA.

Rainbow trout (Oncorhynchus mykiss) were exposed to a 5-min handling disturbance to mimic an acute stressor episode, and levels of plasma GH, IGF-I, and IGFBPs at 0, 1, 4, and 24 h post-stressor exposure were measured. An unstressed group was also sampled at the same clock times (09:00, 10:00, 13:00, and 08:00 [the following day]) as acute stress sampling to determine temporal changes in the above somatotropic axis components. The acute stressor transiently elevated plasma cortisol and glucose levels at 1 and 4 h post-stressor exposure, whereas no changes were seen in the unstressed group. Plasma OH levels were not affected by handling stress or sampling time in the unstressed animals. Plasma IGF-I levels were significantly depressed at 1 and 4 h post-stressor exposure, but no discernible temporal pattern was seen in the unstressed animals. Using a western ligand blotting technique, we detected plasma IGFBPs of 21, 32, 42, and 50 kDa in size. The plasma levels of the lower-molecular-weight IGFBPs (21 and 32 kDa) were unaffected by handling stressor, nor were there any discernible temporal patterns in the unstressed animals. By contrast, the higher-molecular-weight IGFBPs (42 and 50 kDa) were affected by stress or time of sampling. Levels of the 42-kDa IGFBP levels significantly decreased over the sampling period in unstressed control animals, but this temporal drop was eliminated in stressed animals. Levels of the 50-kDa IGFBPs also decreased significantly over the sampling time in unstressed trout, whereas handling disturbance transiently increased levels of this IGFBP at 1 h but not at 4 and 24 h post-stressor exposure compared with the control group. Overall, our results suggest that acute stress adaptation involves modulation of plasma IGF-I and high-molecular-mass IGFBP levels (42 and 50 kDa) in rainbow trout. (C) 2011 Elsevier Inc.

The western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), is a damaging pest and tospovirus vector that has invaded most of the world, and competitive superiority is considered one of the main reasons for this species' success. 3. However, a recent study demonstrated that competition between larval F. occidentalis and a native thrips species may be limiting F. occidentalis abundance in much of the eastern United States. Frankliniella occidentalis also has a limited abundance in central and southern Florida, which is dominated by the endemic F. bispinosa (Morgan). The potential for interspecific competition to limit F. occidentalis abundance in Florida was assessed. 4. The effects of competition between F. occidentalis and F. bispinosa on adult reproduction on a common host (Capsicum annuum L.) were quantified, using a response surface experimental design and a combination of linear and non-linear competition models. 5. Evidence of symmetric competition between these thrips species was found, but contrary to expectations, F. occidentalis reproduced more in dense interspecific populations than F. bispinosa. These results suggest that, unlike most of the eastern US, interspecific competition is not important in limiting F. occidentalis abundance in central and southern Florida.

TI Impacts of fire exclusion and recent managed fire on forest structure in old growth Sierra Nevada mixed-conifer forests SO ECOSPHERE LA English DT Article DE fire ecology; fire management; forest ecology; restoration AB We re-sampled areas included in an unbiased 1911 timber inventory conducted by the U. S. Forest Service over a 4000 ha study area. Over half of the re-sampled area burned in relatively recent management-and lightning-ignited fires. This allowed for comparisons of both areas that have experienced recent fire and areas with no recent fire, to the same areas historically based on early forest inventories. Our results indicate substantially altered present forest conditions, relative to the 1911 data, and can largely be attributed to the disruption of the key ecosystem process for these forests, fire. For areas that burned recently there was a noticeable difference in forest structure based on fire severity. Current tree density and canopy cover in areas burned recently with moderate severity did not differ from 1911 estimates, while areas that burned recently with low severity or were unburned had higher tree density and canopy cover relative to the 1911 estimates. This emphasizes an important distinction with regard to using fire to restore forests, resting primarily on whether fires kill trees in the lower and intermediate canopy strata. Our results also demonstrate nearly a doubling of live tree carbon stocks in the present forest compared to the historical forest. The findings presented here can be used by managers and ecologists interested in restoring Sierra Nevada mixed conifer systems.

TI Mixed-severity fire regimes: lessons and hypotheses from the Klamath-Siskiyou Ecoregion SO ECOSPHERE LA English DT Article DE Biscuit Fire; ecosystem response to fire; fire behavior; fire mosaic; fire regime; fire severity; Klamath-Siskiyou Ecoregion; post-fire ecology AB Although mixed-severity fires are among the most widespread disturbances influencing western North American forests, they remain the least understood. A major question is the degree to which mixed-severity fire regimes are simply an ecological intermediate between low-and high-severity fire regimes, versus a unique disturbance regime with distinct properties. The Klamath-Siskiyou Mountains of southwestern Oregon and northwestern California provide an excellent laboratory for studies of mixed-severity fire effects, as structurally diverse vegetation types in the region foster, and partly arise from, fires of variable severity. In addition, many mixed-severity fires have occurred in the region in the last several decades, including the nationally significant 200,000-ha Biscuit Fire. Since 2002, we have engaged in studies of early ecosystem response to 15 of these fires, ranging from determinants of fire effects to responses of vegetation, wildlife, and biogeochemistry. We present here some of our important early findings regarding mixed-severity fire, thereby updating the state of the science on mixed-severity fire regimes and highlighting questions and hypotheses to be tested in future studies on mixed-severity fire regimes. Our studies in the Klamath-Siskiyou Ecoregion suggest that forests with mixed-severity fire regimes are characterized primarily by their intimately mixed patches of vegetation of varied age, resulting from complex variations in both fire frequency and severity and species responses to this variation. Based on our findings, we hypothesize that the proximity of living and dead forest after mixed-severity fire, and the close mingling of early-and late-seral communities, results in unique vegetation and wildlife responses compared to predominantly low-or high-severity fires. These factors also appear to contribute to high resilience of plant and wildlife species to mixed-severity fire in the Klamath-Siskiyou Ecoregion. More informed management of ecosystems with mixed-severity regimes requires understanding of their wide variability in space and time, and the particular ecological responses that this variability elicits.

TI Seasonal flight activity by the Asian citrus psyllid in east central Florida SO ENTOMOLOGIA EXPERIMENTALIS ET APPLICATA LA English DT Article DE Diaphorina citri; dispersal; huanglongbing; citrus greening disease; Hemiptera; Psyllidae; Candidatus Liberibacter asiaticus; Rutaceae; Citrus sinensis; Citrus limon ID HOST PLANTS; HEMIPTERA; ABUNDANCE; DISEASE; SHOOTS AB The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae), is an important invasive citrus pest in the USA because it vectors a bacterium responsible for huanglongbing, a devastating disease of citrus. Information was lacking on seasonal aspects of flight activity by D. citri, which could have ramifications on psyllid management as well as our understanding of epidemiology of the disease. Of interest from a pest management standpoint would be whether D. citri regularly disperses to or away from citrus on a predictable schedule. In research presented here, seasonal flight activity by D. citri was investigated using yellow sticky traps deployed in citrus trees and in fallow areas adjacent to citrus. Results indicated that flight activity by both male and female D. citri away from citrus can occur at any time of the year with consistent dispersal activity during the spring. The research further indicated citrus is continually subject to infestation by immigrating adults and that there is no time during the year that a citrus grower could be assured immigration would not occur. Growers should be aware that adult dispersal occurs regularly during spring and they should time management tactics accordingly. Adult flight activity 2 m from a citrus tree was more pronounced at 1 m above ground than at 2 or 3 m high. At distances of 8-60 m from trees, numbers of adults on traps were similar among the three heights. Males and females were similar with respect to seasonal flight activity. Numbers of adults captured on traps distant from citrus were not correlated with wind speed, sunlight, or air temperature, but there was some evidence that relative humidity influenced flight activity. Although the D. citri life cycle is dependent on flush, data from these studies did not confirm that psyllid dispersal from citrus consistently increases as citrus flush abundance decreases.

This study was conducted to estimate dry matter (DM) and N partitioning parameters in corn (Zea mays L) as affected by N source, N timing, and crop rotation. We quantified yield by combine, aboveground DM accumulation [residues (stalk + cob) and grain], and C and N concentrations at growth stage R6 of corn continuously cropped (CC) or in rotation with soybean [Glycine max (L) Mem] (CS) and fertilized with side-dressed urea-ammonium nitrate (UAN) or with liquid swine manure applied in either spring (SM) or fall (FM). Of the assessed N partitioning parameters. N utilization showed the highest association with yield (r = 0.94***). Across treatment means, 72% of these increases in N utilization could be attributed to increases in N uptake. On the contrary, N harvest index (NHI) exhibited nearly constant values across experimental units, and therefore. NHI showed a minor relative contribution to variations in N utilization, thus supporting the basic premise of low NHI dependency on environment or management. Both N uptake and N utilization were driven by type of N addition (UAN > manure). Also, corn N utilization and yield were greater (10-13%) within the corn-soybean rotation, suggesting that a shift in land use from crop rotations into more continuous corn due to increasing demand for corn grain may impose additional challenges for enhancing plant N nutrition and sustaining yield.
