The 2.4-L containers containing a low-fertility, acid-based substrate were placed in an unheated greenhouse and subjected to environmental conditions often used for production of azaleas and camellias. Leachate from containers was collected weekly and monitored for pH, electrical conductivity, and concentrations of NH4+ N, No3-N, total P and total K. Leachate concentrations of all nutrients were relatively high during the first 10 to 20 weeks of the study, and then gradually decreased during the remaining portion of the experiment. Differences were observed among fertilizer types, with Multicote often resulting in higher concentrations of N, P, and K in leachates compared to the leachates from the other fertilizer types during the first half of the study. Concentrations of NO3- and P from all fertilizer types were often above permissible levels as cited in the federal Clean Water Act. C1 Univ Calif Riverside, Riverside, CA 92521 USA.

Arturo TI Post-frontier forest change adjacent to Braulio Carrillo National Park, Costa Rica SO HUMAN ECOLOGY LA English DT Article DE land use and land cover change; forest transition; national park buffer zones; sustainable development; Costa Rica ID LAND-COVER CHANGE; TRANSITION; DEFORESTATION; CONSEQUENCES AB Effective biodiversity conservation in national parks depends to a large extent on adjacent forest cover. While deforestation and forest fragmentation as a result of colonization and agriculture have been widespread in neotropical countries over the past few decades, in some places agricultural intensification, wage labor, and rural to urban migration are becoming the most important emerging trends. Changes like this have resulted in forest recovery in other places, mostly in temperate zones, but there have been few studies of this phenomenon in the tropics. This paper presents a case study from a national park buffer zone in Costa Rica. An expansion of Braulio Carrillo National Park (BCNP) in 1986 forced the closing of a frontier that had been characterized by spontaneous colonization and widespread forest-to-pasture conversion. After that time, the Sarapiqui region surrounding the northern sector of BCNP underwent a dramatic social and economic transformation. Population more than doubled, new roads created easy access to a coastal port and the capital city (San Jose), industrial agriculture and ecotourism enterprises expanded, and population and urbanization along major highways increased. In spite of government reforestation and forest protection programs and changes in rural people's attitudes favoring forest conservation, we find that there has been only slight detectable forest recovery in satellite imagery and that forest fragmentation continued, even in remote rural areas near BCNP with stable or shrinking population. We attribute this to the consolidation of landholdings into large cattle ranches and smaller hobby ranches, driven by an inflow of capital from urban areas and developed countries. This pattern has important implications for the management of this and other national park buffer zones. We suggest that strategies focused only on sustainable land use inside buffer zones are unlikely to succeed when carried out in a context of certain macro-level changes. Conservation of endangered biological resources will only be possible if we broaden our thinking about national parks and adjacent lands in the tropics to address new land ownership and use patterns that are occurring as a result of globalization, urbanization, and expanding wage labor employment.

In preparation for the Hydros mission, an observation system simulation experiment (OSSE) has been conducted. As a part of this OSSE, the potential for retrieving useful surface soil moisture at spatial resolutions of 9 and 3 km was explored. The approach involved optimally merging relatively accurate 36-km radiometer brightness temperature and relatively noisy 3-km radar backscatter cross section observations using a Bayesian method. Based on the Hydros OSSE data sets with low and high noises added to the simulated observations or model parameters, the Bayesian method performed better than direct inversion of either the brightness temperature or radar backscatter observations alone. The root-mean-square errors of 9-km soil moisture retrievals from the Bayesian merging method were reduced by 0.5 %vol/vol and 1.4 %vol/vol from the errors of direct radar inversions for the entire OSSE domain of all 34 consecutive days for the low and high noise data sets, respectively. Improvement in soil moisture estimates using the Bayesian merging method over the direct inversions of radar or radiometer data were even more significant for soil moisture retrieval at 3-km resolution. However, to address the representativeness of these results at the global and multiyear scales, further performance comparison studies are needed, particularly with actual field data.

The L-band radar was also shown to be sensitive to near surface soil moisture. However, the spatial resolution of a typical satellite L-band radiometer is of the order of tens of kilometers, which is not sufficient to serve the full range of science needs for land surface hydrology and weather modeling applications. Disaggregation schemes for deriving subpixel estimates of soil moisture from radiometer data using higher resolution radar observations may provide the means for making available global soil moisture observations at a much finer scale. This paper presents a simple approach for estimation of change in soil moisture at a higher (radar) spatial resolution by combining L-band copolarized radar backscattering coefficients and L-band radiometric brightness temperatures. Sensitivity of AIRSAR L-band copolarized channels has been demonstrated by comparison with in situ soil moisture measurements as well as PALS brightness temperatures. The change estimation algorithm has been applied to coincident PALS and AIRSAR datasets acquired during the SMEX02 campaign. Using AIRSAR data aggregated to a 100-m resolution, PALS radiometer estimates of soil moisture change at a 400-m resolution have been disaggregated to 100-m resolution. The effect of surface roughness variability on the change estimation algorithm has been explained using integral equation model (IEM) simulations. A simulation experiment using synthetic data has been performed to analyze the performance of the algorithm over a region undergoing gradual wetting and dry down.

For better accuracy, a pair of horn-lens antennas was used and time-domain gating was applied to the main response. Variations of the dielectric properties with frequency and, physical properties such as bulk density, moisture content, and temperature were investigated. Both the dielectric constant and the loss factor decreased with frequency and increased linearly with bulk density, moisture content, and temperature. Three different approaches are used to correlate the measured dielectric properties and physical properties. Explicit relationships between the dielectric properties and the different physical properties are given at a midrange frequency of 7.0 GHz as an example. The potential use of these relationships is shown for the development of indirect methods for the nondestructive and instantaneous determination of the physical properties of cereal grain and seed from measurements of their dielectric properties. Different sources of error in attenuation and phase shift measurement are discussed, and their effects on the accuracy for the determination of the relative complex permittivity and physical properties are investigated.

Modo-UG is expressed as three alternatively spliced mRNA forms, all of which encode a transmembrane form with a short cytoplasmic tail that lacks phosphorylation sites typically found in classical class I molecules. The three alternative mRNAs would encode a full-length form, an isoform lacking the alpha 2 domain, and one lacking both alpha 2 and alpha 3 domains. Genotyping both captive-bred and wild M. domestica from different geographic regions revealed no variation in the residues that make up Modo-UG's peptide-binding groove. Modo-UG's low polymorphism is contrasting to that of a nearby class I locus, Modo-UA1, which has a highly polymorphic peptide-binding region. Absence of functional polymorphism in Modo-UG is therefore not a general feature of opossum class I genes but the result of negative selection. Modo-UG is the first MHC linked marsupial class I to be described that appears to clearly have nonclassical features. C1 Univ New Mexico, Dept Biol, Albuquerque, NM 87131 USA.

To investigate how biotilm growth of HEp-2 tissue culture cells affects gene expression in Salmonella, we compared global gene expression during planktonic growth and biofilm growth. Microarray results indicated that the transcription of similar to 100 genes was substantially altered by growth in a biofilm. These genes encode proteins with a wide range of functions, including antibiotic resistance, central metabolism, conjugation, intracellular survival, membrane transport, regulation, and fimbrial biosynthesis. The identification of five fimbrial gene clusters was of particular interest, as we have demonstrated that type 1 fimbriae are required for biofilm formation on HEp-2 cells and murine intestinal epithelium. Mutations in each of these fimbriae were constructed in S. enterica serovar Typhimurium strain BJ2710, and the mutants were found to have various biofilm phenotypes on plastic, HEp-2 cells, and chicken intestinal tissue. The pef and csg mutants were defective for biofilm formation on each of the three surfaces tested, while the lpf mutant exhibited a complete loss of the ability to form a biofilm on chicken intestinal tissue but only an intermediate loss of the ability to form a biofilm on tissue culture cells and plastic surfaces. The bcf mutant displayed increased biofilm formation on both HEp-2 cells and chicken intestinal epithelium, while the sth mutant had no detectable biofilm defects. In all instances, the mutants could be restored to a wild-type phenotype by a plasmid carrying the functional genes. This is the first work to identify the genomic responses of Salmonella to biofilm formation on host cells, and this work highlights the importance of fimbriae in adhering to and adapting to a eukaryotic cell surface. An understanding of these interactions is likely to provide new insights for intervention strategies in Salmonella colonization and infection.

Recently, complete sequencing of the A. marginale genome has identified an expanded set of genes, designated omp1-14, encoding new members of this superfamily. Transcriptional analysis indicated that, with the exception of the three smallest open reading frames, omp2, omp3, and omp6, these superfamily genes are transcribed in A. marginale-infected erythrocytes, tick midgut and salivary glands, and the IDE8 tick cell line. OMPs 1, 4, 7 to 9, and I I were confirmed to be expressed as proteins by A. marginale within infected erythrocytes, with expression being either markedly lower (OMPs 1, 4, and 7 to 9) or absent (OMPI I) in infected tick cells, which reflected regulation at the transcript level. Although the pfam01617 superfamily includes the antigenically variable MSP2 and MSP3 surface proteins, analysis of the omp1-14 sequences throughout a cycle of acute and persistent infection in the mammalian host and tick transmission reveals a high degree of conservation, an observation supported by sequence comparisons between the St. Maries strain and Florida strain genomes.

The following strains of E. coli O157:H7 were used in the cocktail: 3027-93, 3055-93, C7927, 43888, C9490, and green fluorescent protein-expressing E. coli O157:H7 B6-914 (GFP EC). Inoculated ground beef was wrapped in polyethylene wrap, vacuum packaged into multilayer barrier bags, heat shrunk and treated with HDP. The initial concentrations of EHEC were 1.29 x 10(3) 2.88 x 10(4), and 2.19 x 10(6) CFU/g. After HDP treatment, the EHEC populations were reduced (P < 0.05) to 9.12 x 10(2), 2.40 x 10(4), and 1.91 x 10(6) CFU/g, respectively. A similar trend was observed for GFP EC which was also enumerated from the cocktail. The GFP EC initial populations of 4.26 x 10(2) and 3.72 x 10(3) CFU/g were reduced to 3.47 x 10(2), and 3.09 x 10(3) CFU/g, respectively. Although the reduction in EHEC populations due to HDP treatment was statistically significant, the practicability of the reduction was marginal. Therefore, other hurdle parameters should be included along with the HDP treatment for more practical inactivation of EHEC in ground beef (c) 2006 Elsevier Ltd. All rights reserved.

The packages were processed to an internal temperature of 71.1 degrees C, ice chilled and stored at various temperatures. The total C. perfringens population was determined by plating diluted samples on tryptose-sulfite-cycloserine agar followed by anaerobic incubation for 48 h at 37 degrees C. At 19 degrees C, C. perfringens levels were consistently about 2.5 log(10) CFU/g until 9.5 h regardless of the presence or absence of Citricidal((R)). However, storage of the unsupplemented marinated chicken samples and those with 50 or 100 ppm Citricidal((R)) samples at 25 degrees C for more than 6 h resulted in rapid growth of C. perfringens, exhibiting 2-3 log(10) CFU/g increase at 7 h. Citricidal((R)) at 200 ppm significantly (p < 0.05) reduced the growth of C. perfringens at both 19 and 25 degrees C. The D-values obtained at 90 degrees C were significantly decreased (p < 0.05) from 14.07 (no Citricidal((R))) to 9.20 min (200 ppm Citricidal((R))). Supplementing marinated chicken products with Citricidal((R)) and the temperature abuses had no consistent effect on color, shear force or lipid oxidation. However, the organism may grow to unsafe levels if sous-vide products are poorly handled or temperature abused for a relatively long period. An extra degree of safety may be assured in such products by supplementation with 100 or 200 ppm Citricidal((R)). Published by Elsevier Ltd.

This was largely based on genotyping of more than 100 T gondii isolates originating from a variety of human and animal sources in North America and Europe. Recent genotyping studies on T gondii strains from wild animals or human patients from different geographical regions revealed the high frequency of non-archetypal genotypes, suggesting the overall diversity of the T gondii population might be much higher than we thought. However, as most genotyping studies had relied on a few biallelic markers, the resolution and discrimnative power of identifying parasite isolates were quite low. To date, there is no commonly used set of markers to genotype T gondii strains and it is not feasible to compare results from different laboratories. Here, we developed nine PCR-restriction fragment length polymorphism markers with each of them capable of distinguishing the three archetypal T gondii alleles in one restriction-enzyme reaction by agarose gel electrophoresis. Genotyping 46 T gondii isolates from different sources using these markers showed that they could readily distinguish the archetypal from atypical types and reveal the genetic diversity of the parasites. In addition, mixed strains in samples could be easily detected by these markers. Use of these markers will facilitate the identification of T gondii isolates in epidentiological and population genetic studies. (c) 2006 Australian Society for Parasitology Inc.

Understanding mediating factors by which micronutrient status affects cognitive function would contribute to elders' quality of life and their ability to remain in the home. Objectives The Nutrition, Aging, and Memory in Elders (NAME) Study is designed to advance the current level of knowledge by investigating potential mediating factors by which micronutrient status contributes to cognitive impairment and central nervous system abnormalities in the elderly. NAME targets homebound elders because they arc understudied and particularly at risk for poor nutritional status. Methods Subjects are community-based elders aged 60 and older, recruited through area Aging Services Access Points. The NAME core data include demographics; neuropsychological testing and activities of daily living measures; food frequency, health and behavioral questionnaires; anthropometrics, gene status; plasma micronutrients. homocysteine, and other blood determinants. A neurological examination, psychiatric examination, and brain MRI and volumetric measurements arc obtained from a sub-sample. Results Preliminary data from first 300 subjects are reported. These data show that the NAME protocol is feasible and that the enrolled subjects are racially diverse, at-risk, and had similar basic demographics to the population from which they were drawn. Conclusion The goal of the NAME study is to evaluate novel relationships between nutritional factors and cognitive impairment. These data may provide important information on potential new therapeutic strategies and supplementation standards for the elderly to maintain cognitivefunction and potentially reduce the public health costs of dementia.

This study discusses market operation in quality-constrained sectors, like gasoline and additives; processors expand output until marginal processing cost equals the processing margin between product revenues and raw material costs; retailers who buy gasoline and additives from processors and sell blended retail gasoline price sales at a marginal cost that includes the blended input value plus adjustments for values of constrained attributes; and market supplies and demands of measurable attributes like octane are balanced. This method can enhance predictions about the effects of new policies that regulate product quality. Analysis can now include price and output adjustment in factor and product markets, and the competitiveness of new processes and products. (c) 2005 Elsevier B.V. All rights reserved.

SO INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROBIOLOGY LA English DT Article ID DEOXYRIBONUCLEIC ACID; STREPTOALLOTEICHUS; SACCHAROTHRIX; ACTINOMADURA; NOCARDIA AB During the course of a phylogenetic evaluation of Saccharothrix strains held in the AIRS Culture Collection, it was discovered that Saccharothrix coeruleoviolacea NRRL B-24058(T) is unrelated to other species within this genus, and a polyphasic study was undertaken to clarify its taxonomic position. Strain NRRL B-24058(T) is observed to be phylogenetically separate from the genus Saccharothrix and is most closely related to the genus Actinoalloteichus. The strain exhibits chemotaxonomic properties that distinguish it from members of Actinoalloteichus, including a whole-cell sugar pattern consisting of galactose and ribose as diagnostic sugars, phosphatidylethanolamine, phosphatidylethanolamine containing 2-OH fatty acids and diphosphaticlylglycerol as the predominant polar lipids and MK-9(H-4) and MK-10(H-4) as the only menaquinones observed. Strain NRRL B-24058(T) is distinct from other taxa within the suborder Pseudonocardineae and a new genus to be named Goodfellowia gen. nov. is proposed.

The ubiquitin proteasome pathway is involved in the regulation of many cellular processes, such as cell cycle control, signal transduction, transcription, and removal of obsolete proteins. The objective of this work was to investigate roles for this proteolytic pathway in controlling the differentiation of lens epithelial cells into lens fibers. METHODS. bFGF-induced cell proliferation was monitored in rat lens epithelial explants by bromodeoxyuridine (BrdU) incorporation. Indicators of lens differentiation included expression of crystallins, lens major intrinsic protein 26 (MIP26), CP49, and filensin and morphologic changes such as cell multilayering and elongation or loss of nuclei. Clasto-lactacystin-beta-lactone, the proteasome-specific inhibitor, was used to study the role of the proteasome in controlling the proliferation and differentiation processes. RESULTS. Explants treated with bFGF initially underwent enhanced proliferation, as indicated by BrdU incorporation and multilayering of the epithelial cells. By 4 days of bFGF treatment, most cells withdrew from the cell cycle, as indicated by diminished BrdU incorporation. After 7 days of treatment with bFGF, lens epithelial explants displayed characteristics of lens fibers, including higher ratios of crystallins to other cytoplasmic proteins and expression of large quantities of MIP26, CP49, and filensin. Adding the proteasome inhibitor to the medium simultaneously with bFGF (day 0) or at day 4 prohibited or delayed bFGF-induced cell proliferation and differentiation. This was indicated by reduced BrdU incorporation and decreased expression of beta- and gamma-crystallins, MIP26, CP49, and filensin. Proteasome inhibition also significantly decreased the number of layers and the sizes of differentiating fibers. CONCLUSIONS. These data show that proteasome activity is required not only for lens cell proliferation but also required for the transition from the epithelial phenotype to the fiber phenotype.

The influence of soil temperature on seedling emergence and early growth of six peanut cultivars (Florida MDR98, Southern Runner, Georgia Green, SunOleic 97R, Florunner and C-99R) was studied in natural field soil profiles in temperature-gradient greenhouses. We evaluated the influence of a range of soil temperatures by sowing at eight dates between January 2001 and May 2002 in Gainesville, Florida. On each sowing date, two additional temperature treatments (ambient and ambient +4.5 degrees C air temperature) were evaluated by sowing on either end of each greenhouse and applying differential heating. In total, 16 different soil temperature treatments were evaluated. Each treatment was replicated four times in four different greenhouses. Mean soil temperature from sowing to final emergence in different treatments ranged from 15 to 32 degrees C. Sowing date, temperature treatment and cultivar had significant effect on seedling emergence and development (V-2 stage). For all cultivars, the lowest germination was observed at the earliest sowing date (coolest soil temperature). Among cultivars, Florida MDR98 was the most sensitive to reduced (cool) temperature with the lowest germination and smallest seedling size at 21 days after sowing, followed by Southern Runner. Georgia Green was the most cold-tolerant with the highest germination, followed by SunOleic 97R. There were no significant differences among cultivars for base temperature, which averaged 11.7 and 9.8 degrees C for rate of emergence and rate of development to V-2 stage respectively. These results imply that cultivar choice and/or genetic improvement of peanut for cold tolerance during emergence and seedling development in regions where cooler soil temperatures persist and/or regions where early sowing is desirable.

However, estimating mineralizable manure N is problematic because of the wide variety of organic manure N forms, as well as the lack of a rapid standardized method. Fourier-transformed infrared spectroscopy (FT-IR) is a promising technology, since it can detect the absorbance of proteins and primary amines, in addition to being instantaneous and non-destructive. Likewise, analytical pyrolysis-mass spectrometry (PyGC/MS) has been used to study lignin and protein composition of forages. We carried out a 10-week laboratory incubation of manure-amended soil in order to test the sensitivity of FT-IR and Py-GC/MS to detect changes in manure during decomposition in soil. Four different dairy or beef manures were included. The manures (0.15 mg manure-N g(-1) soil) were placed inside mesh bags during the soil incubation to allow for the recovery and analysis of fresh as well as decomposed manure. Infrared spectroscopy of the fresh and incubated manures showed that this technique is sensitive to changes in manure organic N after soil application. Bands associated with primary amines decreased during the incubation, while bands associated with proteins increased during manure decomposition. Bands associated with fatty acids tended to decrease during the incubation, possibly due to utilization as C sources. The spectroscopic data also showed that lignin-specific signals increase during manure decomposition, suggesting that the relative amount of lignin in manure increases as it decomposes in soil. The changes in peak areas of pyrolyzates were related to changes in manure constituents during decomposition. The Py-GC/MS data showed qualitative changes in manure lignin during decomposition. The relative amounts of nitrogen containing pyrolyzates, such as phenylacetonitrile and methylindole, changed during the decomposition, but the changes were not consistent across manures. In summary, this experiment showed that the use of manure bags is valuable in discerning between the N cycling dynamics of manure and soil, and that infrared spectroscopy, as well as Py-GC/MS show potential as analytical tools to study manure decomposition in soil.

Observed individual animal data on the average daily DMI (OFI), ADG, and carcass measurements were obtained from postweaning records of 504 steers from 52 sires (502 with complete data). The experimental data and daily temperature and wind speed data were used as inputs to predict average daily feed DMI (kg) required (feed required; FR) for maintenance, cold stress, and ADG; maintenance and cold stress; ADG; maintenance and ADG; and maintenance alone, with CVDS (CFRmcp, CFRmc, CFRg, CFRmg, and CFRm, respectively) and DECI (DFRmcg, DFRmc, DFRg, DFRmp, and,DFRm, respectively). Genetic parameters were estimated by REML using an animal model with age on test as a covariate and with genotype, age of dam, and year as fixed effects. Regression equations for observed on predicted DMI were OFI = 1.27 (SE = 0.27) + 0.83 (SE = 0.04) x CFRm,9 [R-2 = 0.44, residual SD (s(y.x)) = 0.669 kg/d] and OFI = 1.32 (SE = 0.22) + 0.8 (SE = 0.03) x DFRmcg (R-2 = 0.53, s(y.x) = 0.612 kg/d). Heritability of OFI was 0.27 +/- 0.12, and heritabilities ranged from 0.33 +/- 0.12 to 0.41 +/- 0.13 for predicted measures of DMI. Phenotypic and genetic correlations between OFI and CFRmcg, CFRmc, CFRg, CFRmg, CFRm, DFRmcg, DFRmc, DFRg, DFRmg, and DFRm were 0.67, 0.73, 0.41, 0.63, 0.78, 0.73, 0.82, 0.45, 0.77, and 0.86 (P < 0.001 for all phenotypic correlations); and 0.95 +/- 0.07, 0.82 +/- 0.13, 0.89 +/- 0.09, 0.95 +/- 0.07, 0.91 +/- 0.09, 0.96 +/- 0.07, 0.89 +/- 0.09, 0.88 +/- 0.09, 0.96 +/- 0.06, and 0.96 +/- 0.07, respectively. Phenotypic and genetic correlations between CFRmcg and DFRmcg, CFRmc, and DFRmc, CFRg and DFRg(,) CFRmg and DFRmg, and CFRm and DFRm were 0.98, 0.94, 0.99, 0.98, and 0.95 (P < 0.001 for all phenotypic correlations), and 0.99 +/- 0.004,0.98 +/- 0.017, 0.99 +/- 0.004,0.99 +/- 0.005, and 0.97 0.021, respectively. The strong genetic relationships between OFI and CFRmcp, CFG(mg,) DFRmcg, and DFRmg indicate that these predicted measures of DMI may be used in genetic evaluations and that DM requirements for cold stress may not be needed, thus reducing model complexity. However, high genetic correlations for final weight with OFI, CFRmcg, and DFRmcg suggest that the technology needs to be further evaluated in populations with genetic variance in feed efficiency.

Use of AA and formation of urea are under enzymatic regulation, suggesting genetic regulation. The current study examined the effects of sire line, sire, and sex on growth characteristics and plasma urea nitrogen (PUN) concentrations in the offspring of 11 Duroc sires and 11 Landrace sires bred to Yorkshire-Landrace dams. Plasma samples were obtained at approximately 107 (age class = 107 d), 128 (age class = 128 d), and 149 (age class = 149 d) d of age from 511 boars, gilts, and barrows group-penned and fed standard finishing diets. Body weight and backfat (BF, mean of 3 measurements) were recorded at the time of blood sample collection. Sex, age class, and their interaction influenced (P < 0.01) BW, BF, and PUN. Predicted traits (i.e., ADG, BW at 21 wk, average daily change in BF, BF at 21 wk, and the mean of 3 PUN measures) were generated. Means (+/- SD) were: ADG, 888 +/- 204 g; BW at 21 wk, 94.2 +/- 12.5 kg; average daily change in BF, 0.083 +/- 0.052 mm; BF at 21 wk, 13.8 +/- 3.0 mm; and the mean of 3 PUN measures, 16.2 +/- 4.4 mg/dL. Predicted weight traits were influenced (P < 0.05) by sire line, and sex influenced (P < 0.01) all predicted traits. Heritability estimates for PUN at 107, 128, and 149 d of age were 0.35 +/- 0.15, 0.21 +/- 0.13, and 0.16 +/- 0.12, respectively. Phenotypic correlations of PUN with growth and fat traits were low. Genetic correlations of PUN measured at 107 d with growth and fat traits were low. However, genetic correlations of PUN measured at 128 or 149 d with growth and fat traits ranged from 0.81 to 0.95. Determination of PUN, as herein, may be of sufficient precision to allow its use in a selection protocol. Selection of pigs with superior growth performance and low PUN may result in a greater efficiency of dietary nitrogen use and a reduced negative environmental impact.

Our objectives were to quantify the changes in heat production of cows after feed restriction and to quantify the effect of level of realimentation on the dynamics of heat production in lightweight cows. Forty 4-yr-old nonpregnant, nonlacting cows (4-breed composite: 1/4 Hereford, 1/4 Angus, 1/4 Red Poll, and 1/4 Pinzgauer) were randomly assigned to receive 1 of 4 levels of a common alfalfa hay source. All cows were feed-restricted [50.0 g of DM/ metabolic body size (MBS, kg of BW0.75); period 1], and individual fed heat production measurements were taken 0, 7, 13, 28, 56, and 91 d after feed restriction (period 1). In period 2, cows were fed their assigned feed level for their treatment after d 91 of restriction: 50.0 (T50.0), 58.5 (T58.5), 67.0 (T67.0), and 75.5 (T75.5) g of DM/MBS. Measures were taken at 7, 13, 28, 42, 56, 91, 119, and 175 d. In period 3, all cows were fed 75.5 g of DM/MBS after their 175-d measurement, and measures were taken at 7, 14, 28, 56, and 112 d later. In period 1, heat production decreased rapidly during the first 7 d of feed restriction, and heat production continued to decrease during the 91-d restriction. Heat production increased rapidly within the first 7 d, but chronic adaptation continued for T75.5 and T67.0 cows. In period 3, heat production increased rapidly during the first 7 d. Heat production scaled for metabolic body size tended to differ among treatments (P = 0.11). Daily heat production increased by 2.5 kcal/d. These data suggest that there is not a lag in heat production during realimentation and that increased recovered energy is associated with a rapid increase in heat production.

Restraint stress or no stress was imposed on sexually inactive (n = 7) and sexually active female- (n = 17) and male-oriented (n = 6) rams in a 2 x 3 factorial arrangement. Rams were assigned to restraint or control within each classification. Rams were habituated to wearing halters and being tethered in separate pens, permitting visual, vocal, and olfactory contact with adjacent rams for 7 d before treatment. After 1 d of habituation, rams were fitted with jugular catheters that were checked twice daily for patency. For restraint stress, rams were laid on their side with their legs tied for 1 h. For no stress, rams were tethered with halters and leads, but their legs were not tied. On the treatment day, blood was collected at 30-min intervals for 3 h followed by 15-min intervals for 1 h before restraint, during 1-h restraint, and for 1 h after liberation from restraint. Then blood was collected at 30-min intervals for an additional 2 h. Blood was collected from controls at similar intervals. Control rams were isolated from stressed rams. Cortisol, LH, and testosterone were measured using RIA. Mixed model analyses with repeated measures were used on transformed data. Average prestress data were used as a covariate. Cortisol increased (P < 0.01) within 15 min after restraint and remained increased until 1.5 h after liberation from 1-h of restraint stress. In contrast, in controls cortisol remained unchanged at 5 ng/ mL. Cortisol did not differ over time among ram classes, and the treatment x ram class x time interaction was not significant. For LH and testosterone, the ram class x time interactions appeared to compromise the ability to identify differences in these hormones, indicating that they were not good endocrine candidates for methods of classifying rams. In conclusion, restraint stress increased cortisol in sexually inactive and sexually active female- and male-oriented rams alike, thus not providing a method to differentiate among ram classes.

Twenty-two pigs (105 kg initial BW) were fed diets containing either 14.5 or 12.0% CP, in combination with either 2.5 or 8.7% cellulose. Pigs were fed twice daily over the 56-d study, with feed intake averaging 2.74 kg/d. Feces and urine were collected after each feeding and added to the manure storage containers. Manure storage containers were designed to provide a similar unit area per animal as found in industry (7,393 cm(2)). Before sampling on d 56, the manure was gently stirred to obtain a representative sample for subsequent analyses. An interaction of dietary CP and cellulose was observed for manure acetic acid concentration, in that decreasing CP lowered acetic acid in pigs fed standard levels of cellulose but increased acetic acid in pigs fed greater levels of cellulose (P = 0.03). No other interactions were noted. Decreasing dietary CP reduced manure pH (P = 0.01), NH4 (P = 0.01), isovaleric acid (P = 0.06), phenol (P = 0.05), and 4-ethyl phenol (P = 0.02) concentrations. Increasing dietary cellulose decreased pH (P = 0.01) and NH4 (P = 0.07) concentration but increased manure C (P = 0.03), propionic acid (P = 0.01), butyric acid (P = 0.03), and cresol (P = 0.09) concentrations in the manure. Increasing dietary cellulose also increased manure DM (P = 0.11), N (P = 0.11), and C (P = 0.02) contents as a percentage of nutrient intake. Neither cellulose nor CP level of the diet affected manure S composition or output as a percentage of S intake. Headspace N2O concentration was increased by decreasing dietary CP (P = 0.03) or by increasing dietary cellulose (P = 0.05). Neither dietary CP nor cellulose affected headspace concentration of CH4. This study demonstrates, that diets differing in CP and cellulose content can significantly impact manure composition and concentrations of VFA, phenol, and indole, and headspace concentrations of N2O, which may thereby affect the environmental impact of livestock production on soil, air, and water.

A 4 x 2 factoral design was used to evaluate 4 stocking rates (3.0, 4.0, 5.0, and 6.0 steers/ha) with or without steroidal implants (200 mg of progesterone + 20 mg of estradiol benzoate). Treatment combinations were randomly assigned to eight 1-ha pastures of E+ Kentucky-31 tall fescue (i.e., treatments were not replicated). Treatment effects were analyzed for ADG, total BW gain per hectare, forage availability, and hair coat ratings. At the conclusion of grazing in the second year (22 June), steers were placed on a bermuda grass [Cynodon dactylon (L.) Pers.] pasture, and rectal temperatures and serum prolactin concentrations were monitored for 10 d to assess carryover effects of stocking rate and steroidal implants on recovery from toxicosis-related heat stress. Forage availability differed (P < 0.001) between years, but there were no year x treatment interactions (P > 0.10). There was an implant x stocking rate interaction (P < 0.05) on ADG. Differences between the slopes in the regression equations indicated that ADG responded to implantation when stocking rates were low, but the response diminished as stocking rate increased. Stocking rate did not influence (P = 0.89) postgraze rectal temperature, but the regression intercept for implanted steers was 0.4 degrees C greater (P < 0.05) than for nonimplanted steers, and the difference was consistent across the entire 10-d fescue-free grazing period. Concentrations of prolactin increased during the 10-d fescue-free grazing period, but trends differed due to an implantation x stocking rate interaction (P < 0.05). Results indicate that implantation with progesterone + estradiol benzoate increases ADG with lower stocking rates, but the effect diminishes with increased grazing intensity. Implantation with steroid hormones increased rectal temperatures, but during a fescue-free grazing period rectal temperatures and serum prolactins for implanted and nonimplanted steers returned to values indicative of a stable and healthy status in a 192- to 240-h (i.e., an 8- to 10-d) period. However, because the treatments used in this study were not replicated, these observations need to be confirmed with replicated studies.

Adult and larval thrips numbers were significantly lower in cotton plots following winter crimson clover cultivation compared with no-cover plots in all 3 years. Thrips numbers did not differ with respect to the in-furrow treatments in the clover plots, but in the no-cover plots, they were significantly higher in the untreated control and DAP treatments compared with the aldicarb treatment. Thrips damage was higher in the no-cover than the clover plots except in the aldicarb treatments. Within the cover crop plots, thrips damage was highest in the control and phorate treatments and similar in the DAP and aldicarb treatments. There was an inverse relationship between the amount of rye residue ground cover and thrips density and thrips damage in cotton and peanuts. There was also an inverse relationship between the density of rye residue and damage to peanuts from Bunyaviridae tospovirus. Cotton yield was reduced in the cover crop plots and was not measured in the rye residue and peanut plots. These results suggest that ground cover alone decreases thrips numbers and thrips damage in both cotton and peanuts and that a winter crimson clover cover and an in-furrow treatment of DAP enhanced plant protection from thrips in cotton.

Of the several strategies used to reduce the economic effect of aflatoxin-contaminated feeds, the inclusion of selective enterosorbents may be the most practical and cost effective. This study evaluated the effectiveness of montmorillonite clay (MC) supplied as NovaSil PLUS on the performance of full-term commercial type broilers. Eight hundred male commercial broiler chickens ( all vaccinated for Marek's disease, Newcastle disease, and bronchitis) were randomly assigned, ( 20 each) to 40 floor pens and fed 1 of the 4 dietary treatments of industry-type corn-soy broiler diets. Treatments consisted of a control feed, control feed plus 0.5% MC (CMC), a feed containing similar to 4,000 ppb aflatoxin (AF), and a feed containing similar to 4,000 ppb aflatoxin plus 0.5% MC (AMC). The starter diet was fed for 3 wk, the grower for 2 wk and, the finisher for 1 wk. Selected birds were randomly retained for specific tissue analyses of blood serum; relative liver, spleen, and kidney weights; and histological examination of sampled organs. The combined data showed that birds fed MC as NovaSil PLUS received significant protection against the effects of the aflatoxin for most parameters measured. This level of protection did not totally protect the birds from the effects of feeding extremely high concentrations of aflatoxin, however, as their performance was not as good as that of the control group. To our knowledge this is the first study addressing the protective effects of MC in full-term broilers fed steam-pelleted feeds more nearly approximating commercial production.

Oviposited eggs from these and additional species ( goose, Muscovy and mule ducks, and Guinea fowl) were examined after 24 to 72 h of storage and at 6-h intervals up to 72 h of incubation. There was variation in the developmental stages of the blastoderm at the time of oviposition between and within the species and strains examined. Although it is recognized that the temporal rate of development will differ between different species and strains, the external features of any embryo in any given stage will be nearly identical.

Increased production time may be required to fill feed demand and feed outages occur if demand is not met. Identifying management strategies to enhance overall feed production rate without compromising broiler performance is warranted. This study examined the effects of adding varying amounts of corn, ground through a roller mill, to pelleted supplements on feed production parameters, growth performance, and intestinal strength of broiler chickens. Four treatments were used from 18 to 41 d, which included a control ( total diet pelleted), and addition of rolled corn to pelleted supplements at 15, 25, and 35% of the corn required in diet formulation. The final diets fed were identical in nutrient composition. Decreasing the amount of ground corn in the pelleted supplement did not affect pellet durability index in the grower diet, but pellet quality declined in the finisher diet. The dietary treatments did not adversely affect final BW gain or feed conversion. Progressive additions of ground corn to pelleted supplement did not affect gizzard weight or peak force intestinal strength. These data indicate that 35% of the formula corn can be added postpellet to reduce electrical cost for grinding and pelleting and improve overall production rate without adversely affecting cumulative growth performance of broilers.

Food-grade organic acids have been shown to be effective in killing bacteria. Placement of organic acids into the cloaca prior to defeathering was tested to determine if such a treatment could lower the number of Campylobacter that escape and contaminate broiler breast skin during automated feather removal. Campylobacter numbers on the breast skin of treated carcasses increased during defeathering but resulted in numbers that were only about 2% of those observed on control carcasses. Placement of food-grade organic acids in the cloaca of broiler carcasses may be useful as a means to lessen the impact of automated defeathering on the microbiological quality of carcasses during processing.

TI Effect of fenbendazole on turkey semen quality SO JOURNAL OF APPLIED POULTRY RESEARCH LA English DT Article DE fenbendazole; sperm; semen; fertility; mobility AB Fenbendazole (FBZ) is an anthelmintic recently approved to treat and control nematode infections in growing turkeys. When administered to growing turkeys there are no detrimental side effects. However, when we used FBZ to treat nematodes in mature breeder toms, we observed a decrease in semen quality and a subsequent precipitous decline in fertility to less than 20% within 6 wk of administration. An experiment was designed to determine the impact of FBZ administration on aspects of spermatogenesis and semen quality. We discovered that although sperm viability and concentration was not significantly affected by FBZ, this drug significantly reduced sperm mobility. However, normal mobility resumed within 6 wk after FBZ administration. Fenbendazole binds to tubulin and interferes with microtubule assembly. Based on testes histology and the immunocytochemical localization of tubulin in spermatids and mature sperm, FBZ had no affect on any aspect of spermatogenesis. We suggest that FBZ may be affecting sperm mobility by some molecular alteration of the sperm tail axoneme or midpiece, both of which are tubulin-containing structures. If a breeding flock of toms become infected with nematode parasites, a flock manager has the following options: do not treat the toms, find an alternative to FBZ, treat the toms with FBZ and increase the sperm number and frequency of artificial inseminations, or treat the toms with FBZ and secure semen from an uninfected tom flock.

Four dietary treatments were implemented consisting of high or moderate nutrient density diets that were provided for the duration of 3 phases ( 1 to 17, 18 to 35, and 36 to 56 d) or 4 phases ( 1 to 17, 18 to 35, 36 to 46, and 47 to 56 d). Provision of a 3- phase schedule did not alter growth performance, meat yield, or diet cost per final BW. Broilers receiving high nutrient diets had improved growth rate and feed conversion from 1 to 35 d. In the 3- phase schedule, birds given the high nutrient density diets had advantages in BW gain and pectoralis minor breast weight. Market changes in meat prices impact differences in gross feeding margins between diets formulated to high or moderate nutrient density more than variation in diet cost.

The search for strategies to reduce particulate matter and ammonia emissions from animal housing has led to considerable interest in the poultry industry for practical systems to reduce these air emissions. Technologies that have been shown to be effective for reducing airborne dust in animal areas include misting with an oil spray, water mists, extra ventilation, and electrostatic space charge systems. An electrostatic space charge system (ESCS) was designed to reduce airborne dust and ammonia emissions from a commercial broiler production house. The ESCS for this application was based on patented technology developed to reduce airborne dust and pathogens. Two commercial broiler houses with built-up litter ( a control house and one outfitted with an ESCS unit) were monitored for dust and ammonia concentrations over a period of 7 flocks. Results of this study indicate the ESCS significantly reduced airborne dust by an average of 43% and reduced ammonia by an average of 13%. Power consumption of the ESCS system was less than 100 W when in operation. Commercial application of this technology within the production house has the potential to improve in-house air quality and reduce particulate emissions.

We conducted eight experiments to examine whether goats offered different mixtures of shrubs containing different phytotoxins (tannins and saponins) would consume more shrub biomass than goats offered one shrub a single phytotoxin (tannin or saponin). In the first three experiments, goats fed a mixture of three tannin-rich shrubs (Quercus ilex, Arbutus unedo, and Pistacia lentiscus) ate more foliage than goats offered only one shrub (23.2 vs. 10.7 g/kg BW; 25.2 vs. 13.4 g/kg BW, and 27.9 vs. 7.9 g/kg BW), regardless of tannin concentration in individual shrub species. Goats also consumed more foliage when offered the same three tannin-rich shrubs than when offered the saponin-rich shrub Hedera helix (25.4 vs. 8.0 g/kg BW). However, goats offered a mixture of the same three tannin-rich shrubs consumed less foliage than goats offered a mixture of two shrubs containing tannins and saponins: Quercus and Hedera (21.6 vs. 27.1 g/kg BW), Arbutus and Hedera (21.8 vs. 27.1 g/kg BW), and Pistacia and Hedera (19.7 vs. 22.0 g/kg BW). Comparison of intake of shrubs containing only tannins or saponins to intake of shrubs containing both tannins and saponins indicated that goats consumed more total biomass when fed with shrubs with both classes of compounds than with either tannins or saponins alone. Our results suggest that goats can increase intake of Mediterranean shrubs high in secondary compounds by selecting those with different classes of phytotoxins. Simultaneous ingestion of shrubs containing tannins and saponins may promote chemical interactions that inhibit toxic effects of these phytotoxins in the intestinal tract. In addition to complementary interactions between tannins and saponins, biological diversity within Mediterranean maquis vegetation also plays a positive role in increasing shrub intake by goats.

Best known as ubiquitous plant pathogens and saprotrophs, the FSSC comprises over 45 phylogenetically distinct species distributed among three major clades. To identify which species are associated with human infections, we generated multilocus haplotypes based on four partial gene sequences from 471 isolates. Of these, 278 were from human patients, 21 were from hospital environments, and 172 were from other sources. Phylogenetic trees inferred from an ergosterol biosynthesis gene (erg-3) were highly discordant with those inferred from the three other partial gene sequences; therefore, this partition was analyzed separately. Multilocus analysis showed that isolates from humans were restricted to but spread throughout clade 3 of the FSSC phylogeny, comprising at least 18 phylogenetically distinct species. The majority (74.5%) of the clinical isolates, however, were associated with four major lineages, designated groups 1 to 4. Groups 1 and 2 were strongly supported as phylogenetic species, whereas groups 3 and 4 were not. Although isolates from ocular infections were found in all four groups, they had a significant tendency to belong to group 3 (P < 0.001). Human clinical isolates shared identical multilocus haplotypes with isolates from plants, other animals, and from hospital environments, suggesting potential nosocomiality. The major finding of this study is that FSSC-associated mycoses of humans and other animals have origins in a broad phylogenetic spectrum, indicating widespread ability to cause infection in this diverse species complex.

There is a need for the industry to adopt a more standardized approach to reporting the rate at which cows exit from the dairy, and to reporting the reasons why cows are replaced and their destination as they exit the dairy. Herd turnover rate is recommended as the preferred term for characterizing the cows exiting a dairy, in preference to herd replacement rate, culling rate, or percent exiting, all of which have served as synonyms. Herd turnover rate should be calculated as the number of cows that exit in a defined period divided by the animal time at risk for the population being characterized. The terms voluntary and involuntary culling suffer from problems of definition and their use should be discouraged. Destination should be recorded for all cows that exit the dairy and opportunities to record one or more reasons for exiting should be provided by management systems. Comparing reported reasons between dairies requires considerable caution because of differences in case definitions and recording methods. Relying upon culling records to monitor disease has been and will always be an ineffective management strategy. Dairies are encouraged to record and monitor disease events and reproductive performance and use this information as the basis for management efforts aimed at reducing the need to replace cows.

Results of preliminary work, using a Rapid Visco Analyzer (RVA) to heat 50-mL aliquots from 6 unique batches of bovine colostrum at 59, 60, 61, 62, and 63 degrees C, suggested that colostrum could be heated to 60 degrees C for up to 120 min without changing viscosity or IgG concentration. This finding was confirmed by heating 50-mL aliquots from 30 unique batches of colostrum in an RVA for 120 min at 60 and 63 degrees C. Heating colostrum to 63 degrees C resulted in an estimated 34% decrease in IgG concentration and 33% increase in viscosity. However, there was no difference in IgG concentration between preheat-treated (73.4 +/- 26.5 mg/mL) and post-heat-treated (74.5 +/- 24.3 mg/mL) samples after heating colostrum to 60 degrees C in an RVA for 120 min. Similarly, viscosity was unaffected after heating colostrum to 60 degrees C in an RVA for 120 min. High quality colostrum (>= 73.0 mg/mL) suffered greater losses of IgG and greater viscosity changes when heated to 63 degrees C than did moderate quality colostrum (< 73.0 mg/mL). However, the effects of colostrum quality were minor if high quality colostrum was only heated to 60 degrees C. The results of a bovine viral diarrhea serum neutralization assay suggested that antibody activity was unchanged after heating colostrum to either 60 or 63 degrees C. However, these results were interpreted as being inconclusive due to a high proportion of missing results because of the congealing of many samples after heat treatment. The results of this study indicate that 50-mL volumes of bovine colostrum can be heat treated at 60 degrees C for up to 120 min in an RVA without affecting IgG concentration or viscosity.

The forage mixtures were 1) orchardgrass plus white clover [2 species (SP)]; 2) orchardgrass, white clover, and chicory (3SP); 3) orchardgrass, tall fescue, perennial ryegrass, red clover, birdsfoot trefoil, and chicory (6SP); and 4) 6SP mixture plus white clover, alfalfa, and Kentucky bluegrass (9SP). Total herbage intake was similar among forage mixtures, averaging 12.0 kg/d across all forage mixtures and years. Milk production and composition were not affected by forage mixture or year, and averaged 34.6 kg/d, 3.4%, and 2.8% for milk production, milk fat percentage, and milk protein percentage, respectively. The conjugated linoleic acid content of milk fat was higher for cows that grazed the 3SP, 6SP, and 9SP mixtures than from cows that grazed the 2SP mixture (1.02 vs. 0.87 g of conjugated linoleic acid/100 g of fatty acids, respectively). Blood glucose, blood urea nitrogen, and nonesterified fatty acids were not affected by forage mixture and averaged 69.2 mg/dL, 13.4 mg/dL, and 277.5 mu Eq/L, respectively. The results of this study indicate that altering the forage mixture in pastures did not affect dry matter intake, milk production, or blood metabolite profiles of lactating cows. The use of complex mixtures of forages in grazing systems should not affect dairy cow performance. C1 USDA ARS, Pasture Syst & Watershed Management Res Unit, University Pk, PA 16802 USA.

This report validates 1) how well data on cow diets, feed analyses, and milk production reflected established feed-milk-manure relationships; and 2) how well farmer-recorded data on manure land application reflected literature values of manure N and P excretion, collection, and loss. Calculated feed N and P use efficiencies ( 18 to 33% and 18 to 35%, respectively) fell within ranges expected for dairy farms. This suggested that our on-farm methods of data collection provided reliable information on relationships among feed N and P intake, secretions in milk, and excretion in manure. On stanchion farms, there were no differences between farmer estimates (kg/farm) of manure P collected ( 1,140) and land-applied ( 1,210) and what would be calculated from the literature ( 1,340). On freestall farms, there were no differences in amounts ( kg/farm) of manure P collected ( 2,889), land-applied ( 2,350), or literature estimates ( 2,675). Manure P applications (kg/ha) to tilled cropland would be similar using either farmer estimates of manure collected and land-applied, or literature estimates. The data provided a snapshot of Wisconsin industry practices, as well as information on the range of feed and manure management practices on individual dairy farms. Improvements to data collection methods would require increased skill and training of both farmers and those responsible for assisting farmers in on-farm data collection and analyses.

(Hymenoptera: Megachilidae), females may enter several nesting holes before locating their nests. Such levels of "wrong hole" visits lead to an increase in the time spent by females locating their own nests, thereby decreasing alfalfa pollination efficiency and possibly healthy brood production. The objectives of this study were to determine the effect of different nesting board configurations in commercial alfalfa leafcutting bee shelters (separating nesting boards, applying a three-dimensional pattern to the boards, applying a color contrast pattern, or applying a combination of three-dimensional and color contrast patterns) on nest location performance, on the incidence of chalkbrood disease, and on the incidence of broodless provisions. Separating the nesting boards inside shelters improved the ability of females to locate their nests. An increase in nest location performance also occurred in boards with the three-dimensional pattern and the combined three-dimensional and color contrast pattern, compared with the uniform board (a standard configuration currently used commercially). The percentage of provisioned cells that were broodless was not statistically different between treatments, but the percentage of larvae infected with chalkbrood decreased by half in the three-dimensional board design, compared with the uniform board.

Typically, passive contact occurs in the insecticide application process, but ants also may actively contact insecticides by digging in treated soil or walking on a treated soil surface. Laboratory experiments were conducted to determine whether fire ant workers would dig sand treated with contact insecticides in two different scenarios: 1) no-choice bioassays where insecticide-treated sand was the only available digging substrate, and 2) two-choice bioassays where nontoxicant sand was also available for digging. Eight insecticides that are currently registered in the United States for imported fire ant control were tested. They include acephate, bifenthrin, carbaryl, cyfluthrin, deltamethrin, gamma-cyhalothrin, permethrin, and pyrethrin. Workers dug the treated sand for every insecticide tested, even at concentrations up to 10 times of the lowest lethal concentration (LLC) which caused 100% mortality in a toxicity bioassay. However, generally, insecticides significantly reduced the digging effort, even at a concentration that did not cause any significant mortality in the toxicity bioassay.

(Heteroptera: Pentatomidae), and its endoparasitoid Trichopoda pennipes (F.) (Diptera: Tachinidae) to acetamiprid, cyfluthrin, dicrotophos, indoxacarb, oxamyl, and thiamethoxam was compared in residual and oral toxicity tests. In the residual toxicity test, cyfluthrin, dicrotophos, and oxamyl were highly toxic to N. viridula. Thiamethoxam was moderately toxic to these insects. Each of the four insecticides was highly toxic to T pennipes after prolonged tarsal contact with dried residues of these chemicals. In the oral toxicity test, where N. viridula fed on food covered with insecticide residues, none of the insecticides were toxic to adults of this stink bug, but acetamiprid, dicrotophos, and thiamethoxam were moderately toxic to the nymphs. In the oral toxicity test, where N. viridula fed on a gel-food containing insecticides, cyfluthrin, dicrotophos, oxamyl, and thiamethoxam were highly toxic to this stink bug. In an oral toxicity test using contaminated sugar water, all of the insecticides were highly toxic to T. pennipes. Because insecticides were as toxic, or more toxic, to T pennipes than to N. viridula, it is extremely important to conserve this parasitoid by applying these insecticides for control of southern green stink bugs only when the pest reaches economic threshold.

The two treatments developed use a chamber temperature of 45 degrees C for 45 min and a chamber temperature of 47 degrees C for 25 min, both under a 1% oxygen, 15% carbon dioxide, -2 degrees C dew point environment. Both these treatments have been shown to provide control of all life stages of western cherry fruit fly while preserving commodity market quality. There was no definitive egg or larval stage, which was demonstrated to be the most tolerant to either controlled atmosphere temperature treatment system treatment. Efficacy tests for both treatments resulted in 100% mortality of > 5,000 western cherry fruit flies in each treatment. These treatments may provide, with further study, quarantine security in exported sweet cherries where western cherry fruit fly is a quarantine concern and fumigation with methyl bromide is not desired.

Methyl bromide (MeBr) fumigation is an internationally accepted treatment for such wood-boring beetles, but the use of MeBr is scheduled for reduction or elimination as alternatives become available. The use of MeBr can be reduced by more efficient and technically sound fumigation techniques, including good circulation and proper loading. Concentration X time products (CxT) reported for A. glabripennis in solid wood timbers were used to test estimated doses in container fumigations conducted in Tianjin and Shanghai, China, during years 2002-2003. We found that CxT products observed were generally adequate and would support reduced doses of MeBr at temperatures intermediate (10.0 and 15.6 degrees C) to the Animal and Plant Health Inspection Service schedule of 80 g and 48 g/m(3) at >= 4.4 and >= 21.1 degrees C, respectively. The use of fans is recommended, and loading of the containers should never reach 100% to allow for better circulation and desorption. Proper use of fans will allow for better aeration and increase safety to inspectors and consignees of containerized fumigated commodities.

Smith), were identified by sequence analysis as potentially being specific to one of the two host strains. Strain specificity was demonstrated for populations in Florida, Texas, Mississippi, Georgia, and North Carolina, with an AciI and SacI site specific to the rice (Oryza spp.)-strain and a BsmI and HinfI site joining an already characterized MspI site as diagnostic of the corn (Zea mays L.) -strain. All four of these sites can be detected by digestion of a single 568-bp polymerase chain reaction-amplified fragment, but the use of two enzymes in separate digests was found to provide accurate and rapid determination of strain identity. The effectiveness of this method was demonstrated by the analysis of almost 200 adult and larval specimens from the Mississippi delta region. The results indicated that the corn-strain is likely to be the primary strain infesting cotton (Gossypium spp.) and that an unexpected outbreak of fall armyworm on the ornamental tree Paulownia tomentosa (Thunb.) Sieb. & Zucc. ex Steud. was due almost entirely to the rice-strain. C1 USDA ARS, Ctr Med Agr & Vet Entomol, Gainesville, FL 32608 USA. USDA ARS, Honey Bee Res Unit, Weslaco, TX 78596 USA.

A loss of ovipositional fidelity to cornfields has allowed the species to circumvent crop rotation as a means of control in part of its range in the United States. Analyses of variation at eight microsatellite loci provided no evidence for general genetic differentiation between samples of western corn rootworm collected in soybean, Glycine max (L.) Merr., fields and those collected in cornfields both inside and outside the rotation-resistance problem area. This result suggests that few or no barriers to gene flow exist between rotation-resistant and -susceptible rootworm populations. The implications of this result for the management of western corn rootworm in North America and Europe are discussed.

We studied the mobility of mass-reared diapaused and nondiapaused Cydia pomonella (L.) with a focus on understanding the effect of mating status and treatment with gamma radiation as these insects are destined for use in an areawide program that uses the sterile insect technique (SIT). Actograph-measured mobility was assessed one gender at a time for 4 h during which the photoperiod transitioned from day to night. We tested 20-30 individuals per treatment. For experiments on the effect of mating status, we used 24-48-h-old adults (diapause [D]-virgin, D-mated, standard [N]-virgin, and N-mated), which is the typical age class that is released in the SIT program. Diapaused females were significantly more mobile than females reared through standard production, whereas no differences were detected in male mobility because of rearing strategy. Mated females were significantly more mobile than virgin females, whereas no difference in mobility because of mating status was detected for males. Mated females were significantly more mobile than mated males. In contrast, virgin females were significantly less mobile than Virgin males. For experiments on the effect of treatment with gamma radiation, adults from all rearing strategies and treatments (D-0Gy, D-100Gy, D-250Gy, N-0Gy, N-100Gy, and N-250Gy), were tested simultaneously. Adult males were tested at two different constant temperatures (25 and 20 degrees C), whereas adult females were tested only at 25 degrees C. For standard-reared adults, we found a significant linear decrease in mobility as the radiation dose increased from 0 to 250 Gy. In contrast, the relationship between mobility and dose of radiation was quadratic for diapaused males and absent for diapaused females. C1 ETH, Inst Plant Sci Appl Entomol, Zurich, Switzerland.

Insect quality also may be influenced by storage conditions and storage duration before field release. We studied the effects of three different constant ambient temperatures (15, 20, and 25 degrees C) and different lengths of adult cold storage (0, 24,48, and 72 h at 2 degrees C) on the locomotor activity of adult Cydia pomonella (L.) mass reared through diapause or standard production protocols. Mobility was assessed in actographs housed in a climate controlled chamber; tests lasted 24 h. We found that adult mobility was significantly higher for both males and females at 25 and 20 degrees C than at 15 degrees C. There were no significant differences in mobility in moths reared through diapause or nondiapaused production protocols. In addition, temporal analysis of the data revealed a significant shift in the diel patterns of activity for both genders when adults were tested at the three different temperatures. Moths exposed to the lower temperature shifted their activity pattern from evening to mid-afternoon, which may be an adaptive behavior to take advantage of the expected warmest period of the day. Diapaused adults were significantly less mobile when stored in the cold (24, 48, or 72 h of storage at 2 degrees C) than were diapaused adults that did not experience cold storage (0 h). However, length of time in cold storage did not significantly influence the mobility of adult codling moths reared through standard production protocols.

Modifications to trapping protocols that increase trap effectiveness should contribute to this eradication effort. Between October 1996 and May 1997 and between September 1997 and April 1998, we compared trap effectiveness, indicated by the numbers of captured weevils, in relation to selected habitat types. Each study period was divided into fall, winter, and spring seasons. Traps were closely associated with seven habitat types, including four types with prominent erect vegetation (brush-lined irrigation canal, brush, sugarcane, and resaca or ox-bow lake) and three types with only low-growing or sparse erect vegetation (irrigation drainage canal, unimproved pasture, and fallow fields). Captures of male and female weevils were statistically similar regardless of season or trapping habitat. Although captures differed significantly among habitats, these differences varied among seasons. Trapping habitats with prominent vegetational features generally produced higher weekly captures of weevils than habitats lacking these features. Also, captures in traps associated with prominent vegetation indicated seasonal differences in weevil activity, with highest captures occurring during the fall. Traps associated with habitats lacking prominent vegetation did not statistically demonstrate seasonal differences. Our results indicate that immediate trap surroundings strongly influence the effectiveness of the boll weevil pheromone trap. These results also suggest that effectiveness of current trapping programs may be improved through purposeful association of traps with selected vegetational features.

We conducted studies in Michigan to evaluate how different tree cutting dates, outdoor storage conditions, and splitting affected A. planipennis survival in firewood logs. In 2002-2003, we cut logs from A. planipennis-infested ash trees each month, from July to October, and stored half of the logs in shade and half in full sun. In 2003-2004, we tested logs cut July-December; stored in sun versus shade; tarped versus untarped; and whole logs versus split logs. For both years, A. planipennis successfully emerged the summer after cutting from logs that represented all treatments and all cutting dates tested. Adult emergence density was significantly lower in logs cut in July and August. In 2003-2004, A. planipennis adult length was significantly shorter, and percentage of mortality was significantly higher for logs cut in August compared with later months. Emergence density was significantly lower for split logs compared with whole logs for all cutting months except for December. There was no significant difference in adult emergence density between logs stored in full sun versus shade in 2002-2003. In 2003-2004, untarped logs in full sun or shade had significantly lower adult emergence densities than tarped logs in the sun or shade. in conclusion, emergence, survival, and size of A. planipennis was significantly reduced if logs were cut early during larval development (July or August); splitting logs and storing them untarped in full sun or shade further reduced adult emergence. No treatment was 100% effective in preventing adult emergence. C1 Michigan State Univ, US Forest Serv, USDA, N Cent Res Stn, E Lansing, MI 48823 USA.

We developed a method using ruthenium red dye to stain stink bug feeding probes and indirectly assess feeding activity in macadamia nuts. By using the staining method, feeding probes were easily detected on the husk, shell, and kernel. Husk probing was highly correlated (0.80-0.90) with feeding and damage to the kernel. Failure rate to detect kernel damage from stained husk probes was generally < 6%. The staining method was equally effective for immature and mature nuts; therefore, N. viridula feeding activity can be monitored throughout the season to evaluate pest management tactics and forecast outbreak populations.

Schrad (Macrophomina), were bioassayed to determine their acaricidal activities against Tetranychus urticae Koch, Tetranychus cinnabarinus (Boisduval), and Tetranychus viennensis Zacher (Acari: Tetranychidae) in the laboratory. Extracts had both contact and systemic toxicity to these mites. Three solvents were tested for preparing crude extracts: petroleum ether, chloroform, and methanol. Methanol was the most effective solvent, extracting 3.11-4.53% of the acaricide. Petroleum ether was the least effective solvent, extracting 1.25-1.54%. However, extracts with chloroform resulted in the highest mite mortality (78.86%), and ultrasound-assisted extraction required the least time (10 min). Concentrated extracts were prepared using chloroform, methyl acetate, or distilled water as a solvent. Mite mortalities from the concentrated extracts by methyl acetate or distilled water were significantly lower than those by chloroform. The mean lethal concentrations (LC(50)) of the extracts by chloroform, methyl acetate, and distilled water to the mites were 0.71 +/- 0.06, 2.08 +/- 0.16 and 8.75 +/- 0.062 mg/ml, respectively. After liquid chromatography and thin layer chromatography, the concentrated extracts by chloroform were separated into seven groups of isolated fractions and tested for acaricidal activity.

In one experiment, workers of Reticulitermes flavipes (Kollar) (Isoptera: Rhinotermitidae) were exposed to treated sand at 0, 50, 100, 250, and 500 ppm chlorfenapyr (wt [AI] /wt sand). Exposed workers were allowed to interact with untreated nestmates for 14 d, after which mortality was assessed. The three colonies responded differently to the treatments in this experiment. For two colonies, donor exposure rates of 500 ppm (as well as 250 ppm for colony B) chlorfenapyr resulted in significantly greater recipient mortality than controls. For colony C, donor chlorfenapyr exposure did not significantly influence recipient mortality. In a second experiment examining donor mortality over time, donor termites exposed to all test concentrations of chlorfenapyr (except for 0 ppm) suffered 100% mortality within 5 d. Analysis of donor termite body washes using gas chromatography indicated a linear uptake of chlorfenapyr by termites over the concentration range studied. Thus, for this concentration range, no upper limit (saturation plateau) of termite uptake for chlorfenapyr was reached. C1 US Forest Serv, USDA, FS SRS, Starkville, MS 39759 USA.

The current study provides a baseline response and resistance potential to Bt in field and laboratory strains of Bajio Trichoplusia ni (Hubner). Differences in susceptibility to Bt among T. ni populations were observed. T. ni neonates collected in Romita, Guanajuato, were more susceptible to Bt than those collected in Salvatierra or San Luis de la Paz, Guanajuato. After five generations of exposure to XenTari in the laboratory, decreased susceptibility was found only in the Salvatierra insects, with an LC(50) that was 2.1-fold greater than that of a Mexican laboratory strain. The XenTari-selected San Luis de la Paz strain was from 16- to 87-fold more resistant to Cry1A protoxins than U.S. (US) and Mexican laboratory strains. Although Cry1Ab is not a component of XenTari, this strain also was significantly less susceptible to Cry1Ab toxin compared with a US strain, with a resistance ratio of 40.4. The larval weights and lengths, pupal lengths, and percentage of pupation were significantly lower for the Salvatierra strain than for all other strains.

Such costs would cause underestimation of resistance frequency if monitoring was based on analysis of males caught in pheromone traps. To develop a DNA-based resistance monitoring program for pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae), we compared the response to pheromone traps of males with and without cadherin alleles associated with resistance to Bt cotton (Gossypium hirsutum L.). When irradiated males from two hybrid laboratory strains with an intermediate frequency of resistance alleles were released in large field cages, the probability of capture in pheromone traps was not lower for males with resistance alleles than for males without resistance alleles. These results suggest that analysis of trapped males would not underestimate the frequency of resistance. As the time males spent in traps in the field increased from 3 to 15 d, the success of DNA amplification declined from 100 to 30%. Thus, the efficiency of a DNA-based resistance monitoring program would be improved by analyzing males remaining in traps for 3 d or less. C1 Univ Arizona, Dept Entomol, Tucson, AZ 85721 USA.

Moench, and their associated noncultivated grass hosts. Greenbugs were collected during May through August 2002 from 30 counties of Kansas, Nebraska, Oklahoma, and Texas. Discounting the presumptive biotype A, five of the remaining nine letter-designated greenbug biotypes were collected; however, biotypes C, F, J, and K were not detected. Biotypes E and I exhibited the greatest host range and were the only biotypes collected in all four states. Sixteen greenbug clones, collected from eight plant species, exhibited unique biotype, profiles. Eleven were collected from noncultivated grasses, three from wheat, and two from sorghum. The most virulent biotypes were collected from noncultivated hosts. The great degree of biotypic diversity among noncultivated grasses supports the contention that the greenbug species complex is composed of host-adapted races that diverged on grass species independently of, and well before, the advent of modern agriculture.

Bioassays used whole plants, leaf discs, or leaf cages to determine susceptibility of commercial lettuce cultivars to N. ribisnigri infestation and to evaluate screening methods for breeding lettuce resistance to N. Hbisnigri. Resistant and susceptible plants were separated in 3 d when using whole plant bioassays. Long-term (>= 7 d) no-choice tests using leaf cages or whole plants resulted in no survival of N. ribisnigri oil resistant plants, indicating great promise of the Nr gene for management of N. ribisnigri. Effective screening was achieved in both no-choice tests where resistant or susceptible intact plants were tested separately in groups or individually and in choice tests where susceptible and resistant plants were intermixed. Leaf discs bioassays were not suitable for resistance screening. All lettuce cultivars without the resistance gene were suitable hosts for N. ribisnigri, indicating the great importance of this pest to lettuce production and the urgency in developing resistant lettuce cultivars to manage N. ribisnigri.

These eggs were exposed for 1, 3, 6, 12, and 18 h and until hatching (continuous exposure) at temperatures of 16, 20, 24, 28, and 32 degrees C and 57% RH until the emergence of first instars. The developmental time and egg mortality were significantly influenced by temperature and exposure periods. At 16 degrees C, hydroprene did not cause differences in developmental time when eggs were exposed for different periods. At temperatures > 16 degrees C, both exposure period and temperature influenced developmental time. The maximum developmental time (15.0 +/- 0.2 d) occurred at 16 degrees C, and the minimum developmental time (3.2 +/- 0.3 d) occurred at 32 degrees C. Mortality increased when eggs were exposed to hydroprene for longer periods at all of the five tested temperatures. The greatest mortality (81.6 +/- 2.1%) occurred when eggs were continuously exposed on treated surfaces at 32 degrees C. We used developmental time instead of rate (1/developmental time) to fit simple linear or polynomial regression models to the development data. Appropriate models for developmental time and mortality were chosen based upon lack-of-fit tests. The regression models can be used in predictive simulation models for the population dynamics of indianmeal moth to aid in optimizing use of hydroprene for insect management.

However, it is not known how the thickness of the DE-treated wheat layer or grain temperature impact effectiveness. Therefore, we conducted an experiment in growth chambers to assess the effect of different surface layers of hard winter wheat combined with DE on spatial distribution, adult survival, and progeny production of lesser grain borer, Rhyzopertha. dominica (F.), and to determine whether temperature and exposure interval modified this effect. When adult lesser grain borers were released in experimental towers containing untreated wheat or wheat admixed with DE to a surface layer depth of 15.2, 22.9, or 30.5 cm, they were able to penetrate all DE layers and oviposit in the untreated wheat below. However, survival was significantly reduced in adults exposed to DE. Survival decreased both with increasing depth of the DE-treated wheat and with exposure interval. Temperature had no effect on adult survival, but significantly more progeny were produced at 32 than at 27 degrees C. Progeny production was inversely correlated with the depth of the DE-treated layer. Vertical distribution patterns of parental beetles were not significantly different among treatments or exposure intervals; however, more insects were found at greater depths at 32 than at 27 degrees C. The F-1 production was reduced by 22% at the thickest DE-treated layer. However, we conclude that this level of survival could leave a residual population of lesser grain borers that would probably be above an allowable threshold for insect damage.

TI Environmental and economic analysis of switchgrass production for water quality improvement in northeast Kansas SO JOURNAL OF ENVIRONMENTAL MANAGEMENT LA English DT Article DE SWAT model; switchgrass production; economic analysis; commodity crops; water quality; sediment yield; surface runoff; soil erosion ID SEDIMENT; MANAGEMENT; BASINS; MODEL AB The primary objectives of this research were to determine SWAT model predicted reductions in four water quality indicators (sediment yield, surface runoff, nitrate nitrogen (NO3-N) in surface runoff, and edge-of-field erosion) associated with producing switchgrass (Panicum virgatum) on cropland in the Delaware basin in northeast Kansas, and evaluate switchgrass break-even prices. The magnitude of potential switchgrass water quality payments based on using switchgrass as an alternative energy source was also estimated. SWAT model simulations showed that between 527,000 and 1.27 million metric tons (Mg) of switchgrass could be produced annually across the basin depending upon nitrogen (N) fertilizer application levels (0-224 kg N ha(-1)). The predicted reductions in sediment yield, surface runoff, NO3-N in surface runoff, and edge-of-field erosion as a result of switchgrass plantings were 99, 55, 34, and 98%, respectively. The average annual cost per hectare for switchgrass ranged from about $190 with no N applied to around $345 at 224 kg N ha(-1) applied. Edge-of-field break-even price per Mg ranged from around $41 with no N applied to slightly less than $25 at 224 kg N ha(-1) applied. A majority of the switchgrass produced had an edge-of-field break-even price of $30 Mg-1 or less. Savings of at least 50% in each of the four water quality indicators could be attained for an edge-of-field break-even price of $22-$27.49 Mg-1. (c) 2005 Elsevier Ltd. All rights reserved.

In most cases, however, the identity of the nest predators is not known with certainty. We monitored active bird nests with infrared time-lapse video cameras to determine which nest predators were responsible for depreciating bird nests in northern New Hampshire. We monitored 64 nests of I I bird species during three breeding seasons, and identified seven species of predators during 14 predation events. In addition, we recorded two instances of birds defending nests from predators and, in both cases, these nests were ultimately lost to predation. These results contrast with other studies in terms of the relatively high proportion of nests depreciated by raptors and mice, as well as the absence of any predation by snakes. The diverse suite of predators in this and other studies is likely to confound our understanding of patterns of nest predation relative to fragmentation and habitat structure.

The objectives of this study were to determine and model transfer coefficients (TCs) between E. coli O15:H7 on beef tissue and high-density polyethylene (HDPE) cutting board surfaces. Four different transfer scenarios were evaluated: (i) HDPE board to agar, (ii) beef tissue to agar, (iii) HDPE board to beef tissue to agar, and (iv) beef tissue to HDPE board to agar. Also, the following factors were studied for each transfer scenario: two HDPE surface roughness levels (rough and smooth), two beef tissues (fat and fascia), and two conditions of the initial beef tissue inoculation with E. coli O15:H7 (wet and dry surfaces), for a total of 24 treatments. The TCs were calculated as a function of the plated inoculum and of the cells recovered from the first contact. When the treatments were compared, all of the variables evaluated interacted significantly in determining the TC. An overall TC-per-treatment model did not adequately represent the reduction of the cells on the original surface after each contact and the interaction of the factors studied. However, an exponential model was developed that explained the experimental data for all treatments and represented the recontamination of the surfaces with E. coli O15:H7. The parameters for the exponential model for cross-contamination with E. coli O15:H7 between beef tissue and HDPE surfaces were determined, allowing for the use of the resulting model in quantitative microbial risk assessment.

Although SE is not often deposited inside the nutrient-rich yolks of naturally contaminated eggs, penetration through the vitelline membrane to reach the yolk contents could result in rapid bacterial multiplication. In previous studies, such penetration has been observed occasionally at warm temperatures during experiments with in vitro egg contamination models. The present study was conducted to determine whether refrigeration affects the frequency of in vitro SE penetration of the egg yolk membrane. After inoculation of small numbers of SE onto the outside of the vitelline membranes of intact yolks, immediate refrigeration of contaminated samples prevented the penetration of SE into the egg yolk contents during 24 h of storage. However, SE penetrated inside the yolk contents in 4% of contaminated egg samples refrigerated after 2 h of storage at 30 degrees C, 15% of samples refrigerated after 6 h of storage at 30 degrees C, and 40% of samples stored at 30 degrees C for 24 h (48 samples per treatment group). These results highlight the value of prompt refrigeration for restricting the opportunities for SE to multiply to high numbers inside the yolks of contaminated eggs.

The ground pork products were 90% lean, 50:50 fat:lean, and 100% fat. Inoculated products were irradiated using a gamma radiation source in a self-contained (137)Cesium irradiator or a 10 MeV accelerator producing electrons (e-beam). The radiation D-10-values (dose required for a 90% inactivation of viable CFU) for Salmonella DT 104 inoculated into 90% lean ground pork, 50:50 fat/lean ground pork, and 100% pork fat and subjected to beta radiation were 0.42 kGy, 0.43 kGy, and 0.43 kGy, respectively. The corresponding radiation D10-values for Salmonella DT 104 subject to gamma radiation were 0.56, 0.62, and 0.62 kGy, respectively. There was no statistical significant difference (P = 0.3) in radiation D10-values for Salmonella in the three products subject to either radiation treatment. Therefore, fat content had no effect. There was a significant difference (P = 0.001) between the radiation D10-values obtained with the two radiation sources. The radiation D10-values were within the reported range for irradiation destruction of Salmonella contaminated raw meat products.

The primary DSC thermogram of gluten showed one glass transition (Tg) at 63C. Neat (pure) PLA also showed a Tg around the same temperature range followed by crystallization (Cry) and a melting (Mel) transition. Different PLA : gluten blends (20:80, 50:50, 80:20) showed a Tg followed by PLA Cry and immediate Mel transitions. However, subsequent heating-cooling cycling of the blend demonstrated a decrease in PLA Cry and Mel transitions and the appearance of a second Tg. The presence of gluten reduced the number of cycles needed to change PLA Cry structure to mostly amorphous. The low PLA Cry indicates an interaction between the two polymers. The TGA data showed slower PLA degradation compared with gluten, where 10% was degraded at 316C while 10% of the gluten degraded at 254C. Solid-state FTIR showed that amide I and II peaks significantly decreased signifying gluten-heat degradation. A strong peak, corresponding to ester formation between gluten and hydrolyzed gluten molecules, appeared at 1750/cm. The esterification increased in the presence of PLA. The phase contrast microscope demonstrated that the melting of PLA starts at 150C, which means that the continuous phase between 150 and 250C was the melted PLA. At 220C, gluten formed a thin layer; and at about 245C, it aggregated. C1 USDA ARS, Natl Ctr Agr Utilizat Res, Peoria, IL 61604 USA.

Irradiation of palmitic acid leads to the formation of 2-dodecylcyclobutanone (2-DCB), a unique radiolytic product formed at part-per-million levels in fats. Recent research has raised the possibility that, like palmitic acid, 2-DCB can also cause DNA strand breaks in human and rodent cells. In order to more fully understand the clastogenic potential of 2-DCB, it was tested for the ability to induce the formation of micronuclei (MN) in human TK6 lymphoblasts. TK6 lymphoblasts were exposed to 13.3, 26.5, and 53 mu M of 2-DCB for 24 h, both with and without exogenous metabolic activation (EMA). The number of MN per 1000 binucleated cells was induced 2.65-fold without MEA, and 2.85-fold in the presence of EMA at the highest 2-DCB concentration of 53 mu M. Cytotoxicity of the TK6 lymphoblasts treated with 53 mu M 2-DCB was 51.7% in the absence of EMA, and 61.7% in the presence of EMA. Thus, like palmitic acid, 2-DCB may be weakly clastogenic against human cells in vitro. Given the amount of 2-DCB that would be consumed when compared with that of its clastogenic parent fatty acid, 2-DCB is unlikely to have any significant impact on human health.

Thus, the objective was to determine the effects of viscosity reduction of sweetpotato puree with alpha-amylase, maltodextrin (MD) addition, and inlet air temperature on the physicochemical characteristics of spray-dried sweetpotato powder. A face-centered cube design was used to evaluate the effects of amylase level (0, 3.75, and 7.5 mL/kg puree), MD concentration (0%, 10%, and 20%), and inlet air temperature (150 degrees C, 190 degrees C, and 220 degrees C) on powder characteristics. Model-fitting using response surface methodology was performed to examine the effects of independent variables on the moisture content, color, water absorption, solubility, particle size, bulk density, and glass transition temperature. The data were fit to a full second order polynomial equation. However, only the linear and quadratic terms proved to be significant for most dried powder attributes. MD significantly increased powder solubility, altered the hue value, and raised the glass transition temperature of the powder. Pretreatment with alpha-amylase resulted in a lower glass transition temperature and a decrease in particle size. Overall, results show that good quality sweetpotato powders can be produced using this drying method, with potential applications in food and nutraceutical products.

Films cast from fish-skin gelatins are stable at room temperature and can act as a barrier when applied to foods. Lysozyme is a foodsafe, antimicrobial enzyme that can also produce gels and films. When cold-water, fish-skin gelatin is enhanced with lysozyme, the resulting film has antimicrobial properties. The objective of this study was to characterize the effect on strength and barrier properties of lysozyme-enhanced fish-skin gelatin gels and films, and evaluate their activity against potential spoilage bacteria. Solutions containing 6.67% fish-skin gelatin were formulated to contain varying levels of hen-egg-white lysozyme. Gels were evaluated for strength, clarity, and viscoelastic properties. Films were evaluated for water activity, water vapor permeability, and antimicrobial barrier capabilities. Fish-skin gels containing 0.1% and 0.01% lysozyme had pH (4.8) and gelling-temperatures (2.1 degrees C) similar to lysozyme-free fish-skin gelatin controls. However, gel strength decreased (up to 20%). Turbidities of gels, with or without lysozyme, were comparable at all concentrations. Films cast with gelatin containing lysozyme demonstrated similar water vapor permeabilities and water activities. Lysozyme was still detectable in most fish gelatin films. More antimicrobial activity was retained in films cast with higher lysozyme concentrations and in films where lysozyme was added after the gelatin had been initially heated. These results suggest that fish-skin gelatin gels and films, when formulated with lysozyme, may provide a unique, functional barrier to increase the shelf life of food products.

Orthonasal and retronasal thresholds for beta-ionone were, respectively, 985 and 490 times higher for nonperceivers than perceivers. For beta-damascenone, the ratios were 690 and 390 times higher for ortho- and retronasal thresholds, respectively. Panelists who could not perceive beta-ionone were otherwise good perceivers of most compounds tested. There were no such difference for alpha-ionone, a constitutional isomer of beta-ionone. All 3 compounds were retested in water using the same panelists. Differences between nonperceivers and perceivers of beta-ionone were 4900 and 4600 times higher for ortho- and retronasal thresholds for nonperceivers, respectively. However, for beta-damascenone, no such differences were found when measured in water. The same panelists could be classified as "perceivers" or "nonperceivers" when beta-ionone was tested in deodorized orange juice or in water. A different panel was used to confirm beta-ionone and beta-damascenone thresholds in water. A greater difference between perceivers and nonperceivers was found for beta-ionone; as with the first panel, there were no differences in sensitivity to beta-damascenone between panelists when the compound was tested in water.

The unintended consequence is we transfer impacts of harvesting and consumption elsewhere. If we believe impacts of harvesting and consumption are primarily positive, we should embrace them locally. If we believe impacts are negative, we should take responsibility for them locally and mitigate them.

This study provides the first complete picture of Forest Service land management litigation. Previous litigation studies limited their examination to published cases and did not analyze final case outcomes. We document the characteristics and final outcomes of 729 Forest Service management cases filed in federal court from 1989 to 2002. The Forest Service won 57.6% of cases, lost 21.3% of cases, and settled 17.6% of cases. It won 73% of the 575 cases decided by federal judges. Plaintiffs seeking less resource use lost more than half the cases they initiated, and plaintiffs seeking greater resource use lost more than two of every three cases they initiated. Most litigation (1) was for less resource use, (2) was based an the National Environmental Policy Act, and (3) challenged logging projects. The data indicate that the agency is less vulnerable in some types of cases and more vulnerable in others. This study provides policymakers, land managers, and stakeholders with accurate data that can help guide policy debate and choices.

The ensemble Kalman filter (EnKF) dynamically derives such information through a Monte Carlo approach and the introduction of random noise in model states, fluxes, and/or forcing data. However, in land data assimilation, relatively little guidance exists concerning strategies for selecting the appropriate magnitude and/or type of introduced model noise. In addition, little is known about the sensitivity of filter prediction accuracy to ( potentially) inappropriate assumptions concerning the source and magnitude of modeling error. Using a series of synthetic identical twin experiments, this analysis explores the consequences of making incorrect assumptions concerning the source and magnitude of model error on the efficiency of assimilating surface soil moisture observations to constrain deeper root-zone soil moisture predictions made by a land surface model. Results suggest that inappropriate model error assumptions can lead to circumstances in which the assimilation of surface soil moisture observations actually degrades the performance of a land surface model ( relative to open-loop assimilations that lack a data assimilation component). Prospects for diagnosing such circumstances and adaptively correcting the culpable model error assumptions using filter innovations are discussed. The dual assimilation of both runoff ( from streamflow) and surface soil moisture observations appears to offer a more robust assimilation framework where incorrect model error assumptions are more readily diagnosed via filter innovations.

Three peaks of ecdysteroids occurring at approximately 24, 30-33 and 45-48 h after ecdysis to the fourth instar larval stage were detected. In the pupa, a large peak of ecdysteroids occurred between 6 and 12 It after ecdysis to the pupal stage. A small rise in ecdysteroids was also detected at the end of the pupal stage. Quantitative reverse transcriptase polymerase chain reaction analyses of the expression of ecdysone receptors and ecdysone-regulated genes showed that the peaks of expression of most of these genes coincided with the rise in ecdysteroid levels during the last larval and pupal stages. In the last larval stage, ecdysteroid titers and mRNA expression profiles of ecdysone-regulated genes are similar to those observed for Drosophila melanogaster. However, in the early pupal stage, both ecdysteroid titers and the expression of ecdysone- regulated genes are somewhat different from those observed in D. melanogaster, probably because the duration of the pupal stage in D. melanogaster is 84 h while in Ae. aeqypti the duration is only 48 h. These data which describe the relationship between ecdysteroid titers and mRNA levels of Ae. aegypti ecdysteroid-regulated genes lay a solid foundation for future studies on the hormonal regulation of development in mosquitoes.

A BlastX search found similarities for two diet-upregulated clones, i.e., the tyrosine-3-monooxygenase gene and the gene for the chitin binding protein, Gasp. The probe generated from the tyrosine-3monooxygenase clone hybridized to two transcripts 2.3 and 1.2 kb in size. The two transcripts were differentially regulated: the 2.3 kb transcript was upregulated in the first and late third instar diet-fed nymphs, whereas the 1.2 kb transcript was upregulated in the second and early third instar diet-fed nymphs. The Gasp gene was upregulated in late third instar nymphs. A positive correlation was found between levels of expression of the isolated genes and the number of generations the insects had been reared on the artificial diet. (c) 2006 Elsevier Ltd.

We used radiotelemetry to study movements of 3 herds of bighorn sheep (Ovis canadensis) that recently colonized previously unoccupied parts of western Montana. These herds also provided a unique opportunity to compare resource-selection patterns in newly colonized habitats, and we used logistic regression in a global information system framework to generate predictive models for females in each herd. We detected relatively long (19- to 33-km) extra-home range movements by males in all 3 herds, and connectivity with nearby bighorn and domestic sheep herds. An information-theoretic approach to model selection revealed greater differences in resource selection among herds than anticipated. Initial evaluation of resource-selection models by resubstituting data showed excellent predictive accuracy (P <= 0.002), but testing models across sites gave mixed results, and in many cases, poor fit (0.001 <= P <= 0.960). High vagility of males and variability in resource selection by females suggests increased potential for future recolonization and connectivity.

Although much laboratory research has investigated food-hoarding tactics of heteromyid rodents, data from natural systems are scarce. We used a combination of fluorescently labeled seeds and observations of focal individuals to evaluate food-hoarding(, behavior in wild Merriam's kangaroo rats (Dipodomys merriami) living in different competitive environments. There was considerable individual variation within populations in the tendency to larderhoard seeds in a burrow versus scatterhoard seeds in widely dispersed locations. However, Merriam's kangaroo rats living in a system where competitors were predominately conspecific scatterhoarded more than those living in a system where conspecifics were less abundant and heterospecific competitors also were present. Also, pilferage was more common between Merriam's kangaroo rats than across species. Comparisons of food hoarding between communities with different species composition indicate that intraspecific variation in behavior may be associated with variation in competitive environments.

There is evidence that X fastidiosa interacts with endophytic bacteria present in the xylem of sweet orange, and that these interactions, particularly with Methylobacterium mesophilicum, may affect disease progress. However, these interactions cannot be evaluated in detail until efficient methods for detection and enumeration of these bacteria in planta are developed. We have previously developed standard and quantitative PCR-based assays specific for X fastidiosa using the LightCycler (R) system [Li, W.B., Pria Jr., L.P.M.W.D., X. Qin, and J.S. Hartung, 2003.

The assays are specific for M mesophilicum and do not amplify DNA from other species of Methylobacterium or other bacteria commonly associated with citrus or plant tissue. Other bacteria tested included Curtobacterium flaccumfaciens, Pantoea agglomerans, Enterobacter cloacae, Bacillus sp., X fastidiosa, Xanthomonas axonopodis pv. citri, and Candidatus Liberibacter asiaticus. We have demonstrated that with these methods we can quantitatively monitor the colonization of xylem by M. mesophilicum during the course of disease development in plants artificially inoculated with both bacteria.

A Pf in the plow layer less than the autumn sample treatment threshold used by consultants was considered the minimum criterion for acceptable resistance, regardless of population density at planting (Pi). Other criteria were ample roots and a Pf lower than on the susceptible control, as in pot studies. In a Texas field in 2001 and 2002, no resistant accessions had Pf less than the control but all did in microplots into which nematodes from Louisiana were introduced. An environmental chamber experiment ruled out nematode genetic variance and implicated unknown soil factors. Pf in field experiments in Louisiana, Mississippi, and Alabama were below threshold for zero, six and four of the accessions and above threshold in the control. Gossypium arboreum A2-87 and G. barbadense GB-713 were the most resistant accessions. Results indicate that cultivars developed from these sources will suppress R. reniformis populations but less than in pots in a single season. C1 USDA ARS, College Stn, TX 77845 USA.

Dietary flavonoids have been reported to possess antiinflammatory and antioxidant properties, but their mechanisms of action and structure-activity relations have not been fully investigated. We hypothesized that differences in antioxidant activity between the structurally similar flavones, luteolin and chrysin (differing only in B-ring hydroxylation patterns), would differentially affect inflammation-associated Cox-2 expression and PGE(2) formation. Pretreatment of RAW 264.7 macrophage-like cells with 25, 50, or 100 mu moI/L concentrations of luteolin inhibited lipopolysaccharide (LPS)-induced Cox-2 protein expression (P < 0.0001). Chrysin pretreatment did not reduce LPS-induced Cox-2 protein expression at any level tested. Conversely, both luteolin and chrysin completely suppressed LPS-induced PGE2 formation (P < 0.001). Luteolin, but not chrysin, inhibited xanthine/xanthine oxidase-g e ne rated superoxide formation at 100 mu mol/L in a cell-free system (P < 0.001). Although both luteolin and chrysin reduced LPS-induced hydroxyl radical formation relative to the positive control (P < 0.001), luteolin was superior to chrysin (P = 0.003). In summary, luteolin and chrysin suppressed PGE2 formation equally well, despite differential effects on Cox-2 protein expression and on superoxide and hydroxyl radical scavenging. These data indicate that flavones may display similar anti inflammatory activity via different mechanisms. C1 USDA, Diet & Human Performance Lab, Beltsville, MD 20705 USA.

Methylselenol has been hypothesized to be a critical selenium metabolite for anticancer activity in vivo. To determine whether tumor cell migration, invasion, and cell cycle characteristics are inhibited by methylselenol, we exposed HT1080 cells to methylselenol. Methylselenol was generated with seleno-L-methionine (a substrate for methioninase). Submicromolar methylselenol exposure led to an increase in the G1 and G2 fractions with a concomitant drop in the S-phase, indicating slower cell growth. Furthermore, methylselenol inhibited the migration and invasion rate of the tumor cells by up to 53 and 76%, respectively, when compared with the control tumor cells. Although all cells had increased matrix metalloproteinase (MMP) enzyme activities of pro-MMP-2 and pro-MMP-9, the active form of IVIMP-2 was decreased in HT1080 cells cultured with methylselenol. In addition, methylselenol increased the protein levels of antimetastasic tissue inhibitor metalloproteinase (TIMP)-1 and TIMP-2. Collectively, these results demonstrate that submicromolar concentrations of methylselenol increase both prometastasis MMP-2 and MMP-9 and antimetastasis TIMP-1 and TIMP-2 expression. The apparent net effect of these changes is the inhibition of pro-MMP-2 activation and carcinogenic potential or activity. C1 USDA ARS, Grand Forks Human Nutr Res Ctr, Grand Forks, ND 58202 USA.

The methyl groups transferred in mammalian DNA methylation reactions are ultimately derived from methionine. High dietary methionine intake might therefore be expected to increase DNA methylation. Because of the circular nature of the methionine cycle, however, methionine excess may actually impair DNA methylation by inhibiting remethylation of homocysteine. Although little is known regarding the effect of dietary methionine supplementation on mammalian DNA methylation, the available data suggest that methionine supplementation can induce hypermethylation of DNA in specific genomic regions. Because locus-specific DNA hypomethylation is implicated in the etiology of various cancers and developmental syndromes, clinical trials of "promethylation" dietary supplements are already under way. However, aberrant hypermethylation of DNA could be deleterious. It is therefore important to determine whether dietary supplementation with methionine can effectively support therapeutic maintenance of DNA methylation without causing excessive and potentially adverse locus-specific hypermethylation. In the viable yellow agouti (A(vy)) mouse, maternal diet affects the coat color distribution of offspring by perturbing the establishment of methylation at the A(vy) metastable epiallele. Hence, the A(vy) mouse can be employed as a sensitive epigenetic biosensor to assess the effects of dietary methionine supplementation on locus-specific DNA methylation. Recent developments in epigenomic approaches that survey locus-specific DNA methylation on a genome-wide scale offer broader opportunities to assess the effects of high methionine intake on mammalian epigenomes.

Data from several studies suggest that mild elevations of homocysteine in plasma area risk factor for occlusive vascular disease. In the Framingham studies we have shown that plasma total homocysteine concentration is inversely related to the intake and plasma levels of folate and vitamin B-6 as well as vitamin B-12 plasma levels. Almost two-thirds of the prevalence of high homocysteine is attributable to low vitamin status or intake. Elevated homocysteine concentrations in plasma are a risk factor for prevalence of extracranial carotid artery stenosis of at least 25% in both men and women. Prospectively elevated plasma homocysteine is associated with increased total and CVD mortality, increased incidence of stroke, increased incidence of dementia and Alzheimer's disease, increased incidence of bone fracture, and higher prevalence of chronic heart failure. This multitude of relationships between elevated plasma total homocysteine and diseases that afflict the elderly point to the existence of a common denominator that may be responsible for these diseases. Whether this denominator is homocysteine itself or whether homocysteine is merely a marker remains to be determined.

Antibodies (IgG) for T. gondii were sought in human sera by an enzyme-linked immunosorbent assay and in cat sera by using the modified agglutination test (MAT). Antibodies were found in 57% of pregnant women. Seroprevalence increased with age; 51% of 15- to 19-yr-old women (100 total) had antibodies versus 60% of 20- to 24-yr-old women (127 total). Antibodies to T gondii (MAT, 1:25 serum dilution) were found in 35% of cats; titers were 1:25 in 7 cats, 1:50 in 4 cats, and 1:500 in 3 cats.

Fungicide sprays have been used extensively to manage Cercospora leaf spot, including the benzimidazole fungicides. Resistance to benzimidazoles has been observed in isolates of C. beticola. The precise genetics of this resistance is not known in this fungus. We tested benzimidazole-tolerant and -sensitive isolates and found a single mutation in the beta-tubulin gene of benzimidazole-tolerant isolates that corresponds to a mutation known to confer benzimidazole tolerance in other ascomycetes. This mutation is predicted to cause a change from glutamic acid to alanine in the protein product. Isolates containing this mutation further show an increased sensitivity to an N-phenylcarbamate, as would be predicted based on the mutant phenotype found in other filamentous fungi. Only a single mutation was found in isolates from different regions of the United States, isolated in different growing seasons.

Batch] tree canopies in orchards. Not well understood, however, is the relationship between terminal growth, lateral branching, and shoot hormone levels that can fundamentally affect tree canopy development. In this experiment, two peach cultivars with widely differing growth habits (Pillar, KV930479 and Standard, 'Harrow Beauty') were budded on 'Lovell' rootstock, planted in the field in 1998, and characterized for shoot morphology and hormone concentrations in 2002 and 2003 (the fourth and fifth leaf, respectively). Auxin (indole-3-acetic acid) and cytokinins (largely trans-zeatin riboside, dihydrozeatin riboside, and isopentenyladenosine) were measured in shoot tips (2002) and current-year shoots (2003) using mass spectrometry. In 2002, Pillar trees had less sylleptic branching, more upright growth, and higher auxin and auxin-to-cytokinin ratios than Standard trees. In Pillar trees in 2003, auxin concentrations and shoot growth were highest in current year shoots; in pruned trees, only auxin levels increased. Peach tree growth habits may be the result of altered hormone metabolism. Growth forms leading to superior production efficiency may be developed by selection based on specific target hormone concentrations and ratios.

Merrill] planting in the northern Great Plains may reduce early crop growth and retard nitrogen (N) fixation. Application of N as starter fertilizer may increase initial growth of soybean, but may also negatively impact N fixation when environmental conditions improve. The objective of this study was to evaluate the impact of low rates of N applied at planting on soybean N fixation and crop growth in the northern Great Plains. A field experiment (2000-2002) was established within a two-year corn [Zea mays (L.)] soybean rotation using a split-plot design with four replications. Whole plots were no-tillage (NT) and conventional tillage (CT) and the split plots were starter fertilizer (two sources x four rates) treatments. Nitrogen sources were either ammonium nitrate (AN) or urea (UR) each applied at 0, 8, 16, and 24 kg N ha(-1). Biomass in both 2000 and 2001 growing seasons increased significantly with increasing N rate at both growth stages (R1 and R7) and at the R1 stage in 2002. Ureide concentration and relative ureide decreased with increasing N rate at the R1 stage in all years, indicating a decrease in N fixation up to that point in crop development. This decrease in N fixation was not present at the R7 stage, but the significant increase in plant growth including yield was still present, indicating possibly that starter fertilizer can positively impact soybean production in the cool environmental conditions of the northern Great Plains. However, the positive impact on plant growth and yield is dependent on in-season environmental conditions and time of planting. C1 USDA ARS, No Grain Insects Res Lab, Brookings, SD 57006 USA.

All plant species, except grasses, acquire Fe2+ from soil after reduction of Fe3+ using the Strategy I mechanism. Although expressing many Strategy I activities, grasses employ the Strategy II mechanism, which involves the synthesis, secretion, and uptake of phytosiderophores that chelate Fe3+ from soil. In recent years, several genes involved in Fe acquisition have been identified in plants. This study examined the phylogenetic distribution of iron-acquisition genes of five dicots, five grasses, and one gymnosperm. Both Strategy I and II plant species possessed either all or some genes for Strategy I. For Strategy II genes, only the five grasses expressed genes for phytosiderophore synthesis. Due to the conservation of Strategy I genes among both Strategy I and II species and absence of Strategy II genes from dicot and gymnosperm species, we concluded that Strategy II in grasses was derived relative to Strategy I.

The objective of this study was to determine relationships among maturity and yield, mineral uptake, and mineral concentration. Primary spring growth of 'Marshall' ryegrass was harvested every 7 d to 56 d maturity and was fertilized with swine effluent containing 254 and 161 kg nitrogen (N) and 42 and 26 kg phosphorus (P) ha(-1) for two years. Yield increased linearly to a maximum of 13.6 mg ha(-1) after 49 d in 2001 and 8.0 mg ha(-1) after 56 d in 2002. Mineral uptake was highly correlated (r > 0.95) with yield and attained a maximum single harvest of 192 kg N ha(-1) and 32 kg P ha(-1) ( mean of two years). Concentration of all minerals except calcium (Ca) declined as ryegrass matured. Low magnesium (Mg) concentration (< 2 g kg(-1) dry matter) increases the risk of hypomagnesemic grass tetany.

Our research objective was to develop a competitive immunoassay using a surface plasmon resonance (SPR) biosensor for the detection of SEA in raw eggs. Homogenized raw eggs were spiked with SEA and clarified by centrifugation at 14,989 x g. Anti-SEA was added to aliquots of the egg supernatants allowing SEA to bind with anti-SEA. The bound complex was separated from the free immunoglobulin G (IgG) by centrifugation. The supernatant was automatically sampled and injected over the SEA sensor surface of the SPR system. The IgG-bound response units were plotted against spiked SEA concentration. SEA was detected in whole egg at 1-40 ng/mL (ppb). The biosensor analysis including the sensor regeneration was 15 min per sample ill all automated system. This biosensor assay call be utilized for SEA detection in liquid eggs.

The biphasic system was composed of 96-well microtiter plates containing Campy-Line agar prepared 2x for all ingredients except for 1 X agar (0.1 mL per well). Samples were prepared in either twofold or fivefold dilution series across separate 96-well plates and directly transferred (0.1 mL) to the agar-containing microtiter plates to create the biphasic system. Biphasic plates were incubated for up to 48 h at 42C either aerobically or microaerobically in a gas mixture of 5% O-2, 10% CO2 and 85% N-2. Campylobacter was recovered in the aerobically incubated biphasic plates; however significantly, greater Campylobacter recovery, was obtained in the biphasic plates incubated microaerobically (P < 0.05). Significantly higher numbers of injured campylobacters from chicken carcass rinse samples were recovered by the biphasic method compared with conventional direct plating techniques (P < 0.05).

TI Distribution and habitat associations of Northern Pygmy-Owls in Oregon SO JOURNAL OF RAPTOR RESEARCH LA English DT Article DE Northern Pygmy-Owl; Glaucidium gnoma; acoustic lure survey; forest management; Oregon; population monitoring; transect sampling AB We conducted acoustic lure Surveys of Northern Pygmy-Owls (Glaucidium gnoma) on 224 transects that were systematically placed in forested areas in Oregon. Our objectives were to determine if pygmy-owls were associated with particular forest types, regions, or with large trees. We also examined temporal variation in numbers of owls located. We detected pygmy-owls at 161 of 224 transects. The mean,number of owls detected per linear km on individual transects was 0.21 (SE = 0.01, range of means = 0-1.07, N = 224). Mean detections per transect were highest in the Western Cascades, intermediate in the Coast Ranges, Klamath Mountains, Eastern Cascades, and Blue Mountains, and lowest in the Willamette Valley and High Desert Ecoregions. The mean number of owls detected per transect was highest in mesic Douglas-fir (Pseudotsuga menziesii) and ponderosa pine forests (Pinus ponderosa), intermediate in conifer/hardwood and mixed-conifer forests, and lowest in alpine conifers, deciduous hardwoods, and western juniper (Juniperus occidentalis) woodlands. Also, the mean number of owls located per transect increased with the average diameter ranking of the dominant overstory trees. The mean number of owls detected per transect declined in July, and there was evidence of a decrease in the number of owls detected per survey station with increasing time after sunrise. Our data suggested that removal of large trees may have reduced numbers of Northern Pygmy-Owls, but this finding needs to be viewed in the context that our surveys also show that this species is a widely-distributed and fairly common forest bird in Oregon.

This study was conducted to examine associations between diet-induced changes in net acid excretion (NAE) and changes in serum parathyroid hormone (PTH), bone resorption, and calcium excretion over a longer period of 60 days. Methods: Forty healthy older men and women were given 0.75 g/kg of protein as meat, 600 mg of calcium, and 400 IU of vitamin D-3 daily and either cereal (acidogenic) or fruit and vegetable (alkalinogenic) foods as substitutes for some of the cereal in their usual diets. Blood and 24-hr urine measurements were made on days 14 (baseline), 44, and 74. Results: In all subjects, change in renal NAE was correlated with changes in serum PTH (r = 0.358, P = 0.023), urinary N-telopeptide (NTX) (r = 0.367, P = 0.020), and urinary calcium excretion (r(P) = 0.381, P = 0.020, after adjustment for diet group, change in PTH, and change in sodium excretion). Conclusions: Diet changes that increase renal NAE are associated with increases in serum PTH, bone resorption, and calcium excretion over a 60-day period.

It was shown that these products have the advantage of possessing the unique properties of each contributing protein and, at the same time, have the potential for generating innovative products. In this present study, we examined separately the properties of microbial transglutaminase-modified proteins, specifically gelatin, whey, and whey protein isolate (WPI), as well as their enzymatically-combined products. The physical properties and molecular weight distribution of the gelatin biopolymers show that the products had higher melting points, viscosities, and molecular weight distributions, and the degree of crosslinking was enhanced by addition of even small amounts of the secondary protein. There is potential that these products from relatively inexpensive sustainable resources may be used as fillers or as coatings in leather processing. To that end, we carried out a filling experiment, using labeled proteins, and showed that the proteins were evenly distributed throughout the hide and, more importantly, were bound and not removed during the washing steps.

In this study we examine the genetic variance among 12 collections of natural populations in southern Thailand by analyzing 7 microsatellite loci. Based on analysis of molecular variance (AMOVA), three geographic populations of An. maculatus are suggested. The northern population exists in western Thailand north of 12 degrees north latitude. Mosquitoes to the south fall into two genetic populations: 1) the middle southern collections located on the west side of the Phuket mountain range between 8 degrees and 10 degrees north latitude, and 2) the southern collections located on the east of the Phuket mountain range located between approximately 6.5 degrees and 11.5 degrees north latitude. AMOVA revealed significant genetic differentiation between northern and middle southern and southern populations. The middle southern population was moderately differentiated from the southern population. Furthermore, gene flow was restricted between proximal collections located on different sides of the Phuket mountain range. Collections separated by 50 km exhibited restriction of gene flow when separated by geographic barriers, whereas greater gene flow was evident among collections 650 km apart but without geographic barriers.

Five concentrations ranging from 10 to 30% of the defatted ultrafiltered-diafiltered (DUD) lupin proteins were prepared. The viscoelastic properties strongly depended on concentrations. Below 12%, the DUD lupin proteins exhibited more fluid-like behavior. At 15%, lupin proteins became more viscoelastic, and above 20%, the viscoelastic solid-like properties became stronger. Below 12%, the high-frequency behaviors of moduli were proportional to omega(3/4), as expected for a semiflexible coil. Above 20%, the high-frequency behaviors of moduli were proportional to omega(1/2), indicating a flexible coil. The nonlinear steady shear rheological properties were also con centration-dependent and showed shear-thinning behavior, which could be described by a power law constitutive model. The trend of the power law exponent shift is very consistent with the linear viscoelastic behavior change with the lupin protein concentration. These results suggest DUD lupin proteins undergo a structural change between 12 and 20%. C1 USDA ARS, Natl Ctr Agr Utilizat Res, Peoria, IL 61604 USA.

Polyalphaolefin (PAO), whose EHD properties have been reported before, was used as the reference synthetic oil. The effect of measurement variables (speed, load, and temperature) on the film thickness of seed oils was consistent with that predicted by EHD theory. Pressure-viscosity coefficients (pvc) calculated from film thickness data at 40 degrees C showed a steady-state value until about 50 nm film thickness, from which the following mean and SD values for CAN, SBO, and JO were obtained (GPa(-1)): 10.0 +/- 0.9, 7.6 +/- 0.7, and 7.3 +/- 0.5, respectively. However, further reduction of film thickness below about 50 nm resulted in an increase of pvc for CAN, but a decrease of pvc for SBO and JO.

There was a significant difference in Fe bioavailability among the five rice genotypes tested, in both the unpolished and polished grain. The range of Fe bioavailability variation in polished rice was much wider than that of unpolished, suggesting the importance of using Fe levels and bioavailability in polished rice grain as the basis for selecting high-Fe rice cultivars for both agronomic and breeding purposes. Milling and polishing the grain to produce polished (or white) rice increased Fe bioavailability in all genotypes. Iron bioavailability in polished rice was high in the UBON2 and Nishiki, intermediate in both IR68144 and KDML105, and low in CMU122. All genotypes had low bioavailability of Fe in bran fraction compared to unpolished and polished grain, except in CMU122. CMU122 contained the lowest level of bioavailable Fe in unpolished and polished grain and bran, because of the dark purple pericarp colored grain and associated tannin content. The level of bioavailable Fe was not significantly correlated with grain Fe concentration or grain phytate levels among these five genotypes tested. The negative relationship between Fe bioavailability and the levels of total extractable phenol was only observed in unpolished (r = -0.83**) and bran fraction (r = -0.50*). The present results suggested that total extractable phenol and tannin contents could also contribute to lowering bioavailability of Fe in rice grain, in addition to phytate.

Culex quinquefasciatus, and Culex nigripalpus to volatiles and compounds associated with bovine and avian blood that were presented in collagen membranes were evaluated in olfactometer and landing assays. The presence of attractants produced by blood was supported by more attraction of all species to blood than water controls in the olfactometer. Females of Ae. aegypti and Cx. quinquefasciatus were more attracted to bovine blood than to avian blood, but there was no difference in Cx. nigripalpus responses. In landing assays. significantly more females of all species landed on casings with blood than on water controls. There was no difference in landing of Ae. aegypti on bovine or avian blood. However, significantly more females of Cx. quinquefasciatus and Cx. nigripalpus landed on avian blood compared to bovine blood. Blood presented in collagen casings was an effective method for evaluating in-flight attraction and landing in all three species. In the olfactometer, several individual compounds elicited attraction in all species, but none were as attractive as blood for all species. In landing assays, several organic acids and sulfides elicited landing, with Ae. aegypti responding to the greatest number of compounds. These assay methods are effective for evaluation of volatile compounds from blood, and although responses were obtained to several compounds, none were as effective as blood in the C olfactometer and landing assays.

DIPTERA; TSETSE-FLIES; BITING FLIES; POPULATIONS AB House flies and stable flies were collected on a Florida dairy farm using a commercial Alsynite sticky cylinder trap that was either used alone or covered with white, blue, or black outdoor awning fabric. Collections of both species of flies were highest on exposed Alsynite (house flies, 506.2 flies/day; stable flies, 19. 1) followed by blue fabric (house flies, 308.1 flies/day; stable flies 12.5). Responses of both species to white and black fabric were 70% lower than to either of the former materials. When blue fabric was used to cover 50% of the surface area of Alsynite cylinders, house fly responses were significantly higher (290.2 flies/day) than to blue fabric alone (165.2); stable fly responses to the bi-colored target were significantly higher (152.6) than to Alsynite alone (93.8). Comparison of fly counts in the blue-covered versus uncovered Alsynite with traps of a single material indicated that house fly attraction to blue fabric was enhanced by the presence of clear Alsynite, whereas stable fly attraction to Alsynite was enhanced by the presence of blue fabric. The presence of blue+Alsynite visual targets increased collections of house flies in pans of dry fly bait but not in baited jug traps. Visual targets treated with 1.2% bifenthrin controlled > 50% and 90% of house flies in large cages by days two and four after placement, respectively.

There was high correlation (R-2 = 0.866) between HS-derived and life cycle outputs for HS values higher than 0.52, suggesting that HS is a good estimator of the life cycle of the tick above a critical threshold of HS values. Scenarios with increased temperatures increased suitable habitats for the tick in southern parts of the study region, extending below parallel 34 degrees S, but suitable habitats remained limited in the west. A concurrent increase in rainfall produced a further increase of HS in these areas. Results from the life cycle model suggest that in areas of suitable habitat, permanent cattle tick populations are most probable if engorged females are introduced during mid-summer.

However, complications with catheter patency during the postoperative and/or experimental period often arise. In order to identify physiological occurrences common with such complications, 10 multicatheterized sheep (61.8 +/- 7.8 kg BW), obtained from a previous nutrient flux study were used for gross and histopathological investigation. Catheters had been surgically placed in a hepatic portal vein (PVC), a hepatic vein (HVC), a distal mesenteric vein (MVC) and a mesenteric artery (MAC). In the previous study, catheters (PVC, HVC and MAC) were used to collect blood samples or infuse (MVC) p-aminohippurate. Catheters were maintained for a total of 58 days prior to necropsy. Histopathological findings indicated that catheter failures were associated with the following tissue responses: (i) thromboses with frequent focal vasculitis; (ii) euplastic tissues associated with extensive fibrosis; (iii) granulomas; (iv) neo-vascularization of the media; (v) calcification processes; and (vi) micro-abscesses. Additional studies are needed that address and incorporate improvement of catheter design and placement to minimize irritation of endothelium, improvement of catheter treatments and therapeutic regimes, and development and use of alternative anti-coagulants. A greater understanding of the mechanisms leading to failure will help researchers improve catheter performance and patency. C1 USDA, ARS, Forage Anim Prod Res Unit, Lexington, KY 40546 USA.

Nine adult Holstein cattle naturally infected with Mycobacterium avium ssp. paratuberculosis were used in a randomized complete block design. Forty-nine blood tubes were collected from each animal and held at 48.9, 37.8, 26.7, 21.1, 15.6 and 4.4 degrees C for 0, 4, 8, 12, 18, 24, 32, 48 and 72 h. Each blood tube was tested with four mycobacterial antigens (two johnin PPDs, an avain PPD and a whole cell sonicate) and four potential positive controls [concanavalin A (conA), phytohaemagglutinin A (PHA), pokeweed mitogen (PWM) and Staphylococcus enterotoxin A (SEA)]. After incubation for 24 h, the plasma was assayed with a commercial IFN-gamma ELISA. Blood stored at 21.1 and 15.6 degrees C maintained the highest ELISA optical densities (OD) over time with severe reduction in OD values at or above 37.8 degrees C. None of the potential positive controls exactly mimicked the antigen response. SEA and PWM were able to elicit a response after the whole blood quit responding to the antigen and conA underestimated the responsiveness. Phytohemagglutinin A was similar to the antigens on an average, but there was significant disagreement among samples. The PPDs were more potent at stimulating IFN-gamma production than the whole cell sonicate. In conclusion, whole blood should be stored/transported at ambient room temperature and stimulated within 12 h of collection. C1 USDA, Agr Res Serv, Natl Anim Dis Ctr, Ames, IA 50010 USA.

As yet, the molecular interactions between the virus and its aphid vectors have not been determined. This is the first report of aphids acquiring CTV from preparations through an artificial membrane and then transmitting it to receptor plants. The BrCA fed across artificial membranes on crude tissue preparations made from CTV-infected bark tissue were able to transmit CTV to virus-free receptor plants at low rates. CTV p20, p27 and p25 proteins, detected by Western blots, were present in all crude tissue preparations from CTV-infected plants. Partially purified CTV preparations were not transmitted by the BrCA in this manner. Infectivity immunoneutralization experiments were conducted where aphids were forced to feed in vitro on three CTV-specific antibodies (p25, p27 and p20) before being placed on receptor plants following a 48 h acquisition feed on CTV-infected source plants. There were no differences in transmission rates among the majority of treatments and the control treatments. However, in one infectivity immunoneutralization experiment, the CTV p20 antibodies significantly enhanced CTV transmission compared to buffer only, pre-immune antiserum or no antibody control treatments. This suggests the inactivity of CTV p20 aids BrCA transmission of virions. (c) 2006 Elsevier B.V. All rights reserved. C1 Texas A&M Univ, Kingsville Citrus Ctr, Weslaco, TX USA.

TI Nesting ecology and survival of scaled quail in the Southern High Plains of Texas SO JOURNAL OF WILDLIFE MANAGEMENT LA English DT Article DE Callipepla squamata; chicks; nesting habitat; nest success; scaled quail; Southern High Plains; survival; Texas ID PATCH SIZE; SUCCESS AB Scaled quail (Callipepla squamata) populations have been declining since the early 1960s, and there is no clear understanding of what is causing this decline. It has been suggested that reproductive failure is a probable cause of this decline. We used radiotelemetry to evaluate nesting ecology and survival of scaled quail in the Southern High Plains of Texas in 1999 and 2000. We radio-marked 138 hens (66 in 1999 and 72 in 2000) and reported nesting activity on 106 nests. In 1999, 50 nests were detected with a nesting success of 44%. In 2000, 56 nests were detected with a nesting success of 64%. Chick survival was recorded at 21 days posthatch and was analyzed as present or absent, as exact numbers were difficult to determine. Two hens had chicks present at 21 days in 1999, but 16 hens had chicks present at 21 days in 2000. Chick presence with the hen at 21 days was negatively associated with cool and wet weather. Logistic regression revealed predictive relationships for models describing vegetation characteristics at and around nest sites as predictors of nesting success and nest sites. Variables in the models included percentage of bare ground, forb diversity, and amount of visual obstruction at different heights. Hen survival, nesting success, and chick survival were higher in 2000 than in 1999. Differences in vegetation composition and structure were likely responses to differences in precipitation between years. Drought and overgrazing by livestock increase the percentage of bare ground and reduce visual obstruction; these are likely contributors to the reduced scaled quail populations in the Southern High Plains.

The resulting models are used to evaluate questions relevant to species conservation, in particular comparing occurrence estimates in reserved and unreserved lands. We used an information-theoretic approach to develop and evaluate a priori models to predict the occurrence of the Del Norte salamander (Plethodon elongatus) within its geographic range on national forests in California. We then evaluated the association of P. elongatus to federal reserved lands using both an empirical and model-based assessment. For the model-based assessment, we calculated the probability of occurrence at existing Forest Inventory and Analysis (FIA) plots that we sampled for salamanders and those that were unsampled within our study area. The Del Norte salamander was more likely to be detected at plots with steeper slopes, older trees, more hardwood basal area, more canopy cover of conifers, more rock, and in areas receiving more precipitation and slightly warmer mean annual temperatures. Only the relationship of percent rock cover to probability of occupancy by P. elongatus was linear. Our best multivariate predictive model explained 66.2% of the deviance, and it correctly classified 96% of the plots at which P. elongatus was detected and 94% of the plots at which it was not. Ten-fold, cross-validation results revealed that the best model was relatively robust with correct classification rates of 87% and 89% for locations at which P. elongatus was detected and not detected, respectively. Our empirical results revealed no strong association with reserved lands. However, when we used our best model to estimate P. elongatus' probability of occupancy at both sampled and unsampled plots, the mean probability of occupancy within reserved lands was greater than in unreserved lands, suggesting that reserved lands have higher-quality habitat relative to nonreserved lands. Overall, our results indicate that systematically collected forest inventory data can have significant value in developing wildlife habitat models when combined with samples of animal occurrence. Robust, empirically derived habitat models, such as the one we developed, may be useful tools for managers for monitoring the quantity, quality, and distribution of a species' habitat.

TI Landscape models to predict the influence of forest structure on tassel-eared squirrel populations SO JOURNAL OF WILDLIFE MANAGEMENT LA English DT Article DE Akaike's Information Criterion; Arizona; density; forest structure; information theory; recruitment; Sciurus aberti; spatial modeling; tassel-eared squirrel ID PONDEROSA PINE FORESTS; ECOLOGICAL RESTORATION; KAIBAB SQUIRREL; ABERT SQUIRREL; HABITAT; MANAGEMENT; ARIZONA; PERSPECTIVE; PATTERNS; MAMMALS AB The tassel-eared squirrel (Sciurus aberti) is often used as an indicator species in southwestern ponderosa pine (Pinus ponderosa) forests. Because of more than a century of fire suppression, grazing, and timber harvest, these forests have become increasingly prone to catastrophic wildfire, resulting in pressure to implement large-scale treatments to reduce fire threat and restore ecosystem function. However such treatments could have dramatic effects on tassel-eared squirrels and other wildlife. Because of emerging plans for thinning southwestern forests to reduce fire threat, we undertook a modeling effort to produce spatial data to examine the results of proposed management actions on squirrel habitat. We used squirrel density and recruitment data from 9 study areas located in the Flagstaff region of northern Arizona, USA, linked with spatial data on forest structure developed from remote-sensing imagery. We used a multiscale approach to analyze relationships between forest structure and squirrel density and recruitment. We then used an information-theoretic approach to identify the most parsimonious models for both squirrel density and recruitment. The most strongly supported models of squirrel density included local-scale basal area and > 60% canopy cover at the 65-ha spatial scale. For squirrel recruitment, 4 different models that included both local-scale basal area (m(2)/ha) and variations of canopy cover over extents of approximately 160-305 ha were strongly supported. Using the most parsimonious models, we created spatial data layers representing both squirrel density and recruitment across an 800,000-ha landscape in northern Arizona. Our approach resulted in spatially explicit models that can be used in efforts to predict the effects of forest management on squirrel populations.

The association of psychological eating behavior constructs with overweight and obesity during early adult life and middle age has been documented in several studies. However, the association of eating behavior with unexplained weight change in old age is relatively unexplored. Methods. Body weight, eating behavior (dietary restraint, disinhibition, and hunger as assessed by the Eating Inventory), reported dietary intake, and physical activity level were assessed at baseline in 36 nonobese postmenopausal women aged 61.3 +/- 3.1 years (mean standard deviation). Measurements were repeated 4.4 +/- 0.9 years later, and changes in body weight were examined in relation to baseline and follow-up eating behavior scores, reported dietary intake, and physical activity level. Results. Participants had no major changes in health or lifestyle characteristics over the study interval. Weight change ranged from -7.5 to +5.8 kg (mean -0.3 +/- 3.5 kg), and there were no significant changes in reported dietary intake. Mean hunger score (calculated as the mean of baseline and follow-up hunger score) predicted weight change per year over the study period (bivariate r = 0.386, p =.020), even in statistical models adjusted for mean dietary intake variables (partial r = 0.658, p =.003). Restraint, disinhibition, and physical activity level did not predict weight change. Conclusions. Reported hunger assessed by the Eating Inventory was associated with unintentional weight change in healthy postmenopausal women. The Eating Inventory questionnaire may provide a clinically useful tool for identifying older individuals at risk of undesirable weight change, and particularly unintentional weight loss, a factor strongly associated with increased morbidity and premature death in this population.

Methods and Results: In Experiment I, faecal samples were collected from steers grazing either endophyte-infected (E+) tall fescue or common bermudagrass (CB). Steers grazing E+ tall fescue were confined to a dry-lot pen and fed CB hay ad libitum for 10 days. In Exp. II, faecal samples were collected from steers grazing either E+ or novel endophyte-infected (NE) tall fescue and treated with one of two anthelmintics: ivermectin (I) or fenbendazole (F). In Exp. I, prevalence of E. coli O157:H7 was less in E+ tall fescue steers fed CB hay than steers grazing CB. More I-treated steers shed Salmonella than F-treated steers at 42-day postanthelmintic treatment but shedding of Salmonella was similar between anthelmintics at day 63 in Exp. II. Conclusions: Faecal shedding of pathogenic bacteria was not affected by grazing E+ tall fescue. Alterations of forage diets may influence the prevalence of E. coli O157:H7, and anthelmintic treatment could affect faecal shedding of Salmonella. Significance and Impact of the Study: Knowledge of factors that influence shedding of pathogenic bacteria in cattle is necessary to develop on-farm intervention strategies aimed at reducing pathogen shedding.

Direct heritability estimates from single-trait analyses were 0.11 for LB, 0.02 for LW, 0.17 for BW, 0.18 for WW, 0.68 for FW, 0.36 for FG, and 0.76 for SL. Estimates of direct genetic correlation were 0.40 between LB and LW, 0.57 between BW and WW, 0.65 between FW and SL, -0.37 between FW and FG and -0.70 between SL and FG. Breeding values (BV) from both single-trait and seven-trait analyses calculated using the parameters estimated from single-trait and two-trait analyses were compared across years of birth with respect to genetic trends. Estimated BV from both analyses for LB, LW, BW, WW and FW increased over time, while those for FG and SL were unchanged. Estimated changes in BV over time did not differ substantially for single-trait and seven-trait analyses, except for traits highly correlated with another trait that was responding to selection (i.e., LB, which was highly correlated to both LW and WW).

Gilts were allocated to a gestation treatment by d 7 after breeding. They were housed in a single room, floors were fully slatted with no bedding, and all conditions except for housing type were identical. Gilts were weighed and their backfat measured at wk 1 (just after moving to gestation housing), 5, 9 and 13 of pregnancy. After farrowing, litter size, sex ratio, piglet weights and mortality percentages were recorded. Skin lesions were scored using a 6-point scale every 2 wk. Gait was scored using a 6-point scale at the end of gestation. Heart rate was assessed at wk 14 to 15 after breeding. Behaviour was videotaped to collect data on body postures and ingestive behaviour for 24 h at wk 4, 6, 9 and 13 of gestation. Apart from at wk 5, when S gilts had higher backfat than G (P < 0.05), G and S gilts did not differ in body weight or backfat during the study. Reproductive performance did not differ. While skin lesion scores did not differ at wk 1, by wk 13 lesion scores for several regions of the head, face, body, feet and legs were higher in G than S animals (P < 0.05). There were no differences in heart rate, but gait scores at the end of pregnancy tended to be poorer in G than S gilts (P < 0.1). As gestation progressed gilts spent less time standing (P < 0.0001) and more time lying (P < 0.05), but behavioural time budgets (percentages of time spent standing, lying, sitting, eating and drinking) of animals housed in G and S did not differ. In conclusion, there were few differences detected between gilts housed for one pregnancy in groups of four or stalls. Stalls in this study were relatively spacious, while group pens were relatively small and barren.

Nothing is known about Toll-like receptor (TLR) expression nor functional activation and cytokine/chemokine gene expression of line A and B heterophils when stimulated with TLR agonists. We found that line A and B heterophils express the same range of TLRs. All the bacterial TLR agonists, peptidoglycan, the synthetic lipoprotein Pam3CSK4, ultra-pure lipopolysaccharide, and flagellin all induced significantly greater functional activation of heterophils from line A compared to B. Only stimulation with the guanosine analog, loxoribine, (LOX) induced a significantly greater functional response in B over A. Additionally, all heterophils from line A stimulated with the bacterial TLR agonists had dramatic upregulation of pro-inflammatory cytokine and chemokine mRNA expression, whereas heterophils from line B had little or no upregulation of these genes. However, stimulation of all heterophils from line B with the bacterial TLR agonists and LOX induced a significant upregulation of IFN-alpha, with little transcription of this cytokine gene in line A heterophils. These findings suggest that the difference in heterophil functional efficiency between these parent lines is due to recognition of pathogens and activation of signaling pathways that induce innate cytokine and chemokine responses.

Preparedness for a crop bioterror event requires a strong national security plan that includes steps for microbial forensics and criminal attribution. However, U.S. crop producers, consultants, and agricultural scientists have traditionally focused primarily on strategies for prevention and management of diseases introduced naturally or unintentionally rather than on responding appropriately to an intentional pathogen introduction. We assess currently available information, technologies, and resources that were developed originally to ensure plant health but also could be utilized for postintroduction plant pathogen forensics. Recommendations for prioritization of efforts and resource expenditures needed to enhance our plant pathogen forensics capabilities are presented.

With the goal of understanding fungal gene expression related to pathogenicity, three cDNA libraries were created by suppression subtractive hybridization using wheat heads inoculated with a highly aggressive strain and either water or a less aggressive strain of this pathogen. Eighty-four fungal genes expressed during initial disease development were identified. The probable functions of 49 of these genes could be inferred by bioinformatic analysis. Thirty-five ESTs had no known homologues in current databases and were not identified by ab initio gene prediction methods. These ESTs from infected wheat heads probably represent F. graminearum genes that previously were not annotated. Four genes represented in one of these libraries were selected for targeted gene replacement, leading to the characterization of a two-component response regulator homologue involved in pathogenicity of the fungus. The mutants for this gene showed reduced sporulation and delayed spread of Fusarium head blight on wheat. C1 Univ Minnesota, Dept Plant Pathol, St Paul, MN 55108 USA.

We conducted parsimony and Bayesian phylogenetic analyses based on nuclear ribosomal DNA internal transcribed spacer and chloroplast trnL intron sequences obtained from 218 of the ca. 255 species of Trifolium, representatives from 11 genera of the vicioid clade, and an outgroup Lotus. We confirm the monophyly of Trifolium, and propose a new infrageneric classification of the genus based on the phylogenetic results. Incongruence between the nrDNA and cpDNA results suggests five to six cases of apparent hybrid speciation, and identifies the putative progenitors of the allopolyploids T. dubium, a widespread weed, and T. repens, the most commonly cultivated clover species. Character state reconstructions confirm 2n = 16 as the ancestral chromosome number in Trifolium, and infer a minimum of 19 instances of aneuploidy and 22 of polyploidy in the genus. The ancestral life history is hypothesized to be annual in subgenus Chronosemium and equivocal in subgenus Trifolium. Transitions between the annual and perennial habit are common. Our results are consistent with a Mediterranean origin of the genus, probably in the Early Miocene. A single origin of all North and South American species is hypothesized, while the species of sub-Saharan Africa may originate from three separate dispersal events. (c) 2006 Elsevier Inc.

TI y4xP, an open reading frame located in a type III protein secretion system locus of Sinorhizobium fredii USDA257 and USDA191, encodes cysteine synthase SO MOLECULAR PLANT-MICROBE INTERACTIONS LA English DT Article ID CULTIVAR-SPECIFIC NODULATION; SYMBIONT RHIZOBIUM-FREDII; GRAM-NEGATIVE BACTERIA; SP STRAIN NGR234; SURFACE APPENDAGES; MOLECULAR-CLONING; SPECIFICITY; EXPRESSION; JAPONICUM; PLASMIDS AB Sinorhizobium fredii USDA257, a soybean symbiont, exports several nodulation outer proteins (Nops) into the rhizosphere. These proteins, which are exported by a type III secretion system (TTSS), have a pivotal role in host-specific nodulation. The entire TTSS of S. fredii lies within a 31-kb region that includes conserved genes that code for secretion machinery proteins, Nops, and several open reading frames (ORF) of unknown function. Identifying the functions of these ORF is essential to understand fully the role of TTSS in nodulation. Here, we report the characterization of y4xP, an ORF of previously unknown function. Southern blot analysis revealed that USDA257 contains two copies of y4xP, while a sibling, USDA191, contains a single copy. The amino acid sequence of Y4XP is homologous to both eukaryotic and prokaryotic cysteine synthase, a key enzyme in sulfur assimilation. The coding region of USDA257 y4xP under control of T7 promoter was expressed in Escherichia coli, and the recombinant protein was purified by nickel-affinity chromatography. Antibodies generated against soybean cysteine synthase cross-reacted with the recombinant protein. A nonpolar mutant of y4xP of USDA191 showed a marked reduction in cysteine synthase activity. Enzyme activity was completely restored when the mutant was complemented with a plasmid containing the y4xP sequence. Cysteine synthase activity was confined to the cell cytosol. Extracellular protein fraction from genistein-induced USDA191 showed no cysteine synthase activity. This observation indicates that cysteine synthase, which is located in the TTSS locus, is not a type III secreted protein. A nonpolar cysteine synthase mutant was able to export all the Nops to the rhizosphere, albeit in reduced amounts compared with the wild-type USDA191. Interestingly, USDA191 cysteine synthase mutant was able to initiate nodules on 'McCall' soybean more efficiently than the wild-type. Our results demonstrate that y4xP encodes a cysteine synthase and inactivation of this gene enhances the ability of USDA191 to form nodules on 'McCall' soybean by regulating Nops production.

Resistance to potato aphid is developmentally regulated and is not associated with induction of a hypersensitive response. The NahG transgene that eliminates endogenous salicylic acid (SA) was used to test the role of the SA signaling pathway in the resistance mediated by Mi-1 to potato aphids. Aphids survived longer on NahG tomato plants than on wild type. However, aphid reproduction was not affected on NahG tomato. Aphid resistance in Mi-1 NahG plants was completely abolished and the phenotype was successfully rescued by application of BTH (benzo(1,2,3)-thiaiazole-7-carbothioic acid S-methyl ester), indicating that the SA signaling pathway is an important component of Mi-1-mediated aphid resistance. Using virus-induced gene silencing, one or more mitogen-activated protein kinase (MAPK) cascades required for Mi-1-mediated aphid resistance were identified. Silencing plants for MAPK kinase (LeMKK2) and MAPKs (LeMPK2 and LeMPK1, or LeMPK3) resulted in attenuation of Mi-1-mediated aphid resistance. These results further demonstrate that resistance gene-mediated signaling events against piercing-sucking insects are similar to those against other plant pathogens.

In monocotyledonous barley, loss-of-function mlo alleles result in effective immunity against the Ascomycete Blumeria graminis f. sp. hordei, the causal agent of powdery mildew disease(2,3). However, mlo-based disease resistance has been considered a barley-specific phenomenon to date. Here, we demonstrate a conserved requirement for MLO proteins in powdery mildew pathogenesis in the dicotyledonous plant species Arabidopsis thaliana. Epistasis analysis showed that mlo resistance in A. thaliana does not involve the signaling molecules ethylene, jasmonic acid or salicylic acid, but requires a syntaxin, glycosyl hydrolase and ABC transporter(4-6). These findings imply that a common host cell entry mechanism of powdery mildew fungi evolved once and at least 200 million years ago, suggesting that within the Erysiphales ( powdery mildews) the ability to cause disease has been a stable trait throughout phylogenesis.

In this paper, we report on the sequencing of the ITS LSU-rDNA and beta-tubulin loci used to identify a fungus isolated from the cuticle of a P. nasuta that emerged from coffee berries infected with the coffee berry borer. The sequences were compared with deposits in GenBank and the fungus was identified as Aspergillus westerdijkiae. The fungus tested positive for ochratoxin A production, with varying levels depending on the media in which it was grown. These results raise the possibility that an insect parasitoid might be disseminating an ochratoxin-producing fungus in coffee plantations.

Greenhouse trials indicated that crimson clover, subterranean clover, and hairy vetch serve as good hosts for R. reniformis. Reproduction factors (Rf) for those crops were 7.2, 2.2, and 3.7, respectively when grown in the greenhouse at an average temperature of 30 degrees C. 'Licapo' rape, 'Tyfon' mustard spinach, 'Barnapoli' rape, P12863 and P14048 canola, produced Rf values of 1.3, 1.1, 1.0, 1.0, and 1.2 as compared to the Rf value of 4.2 on cotton when grown at an average temperature of 21 degrees C. Varieties of radish, black mustard, white mustard, canola, lupin, ryegrass, wheat, oats, and rye produced Rf values of less than I indicating R. reniformis did not reproduce on these hosts. In microplot and field trials, P, reniformis population densities did not increase on crimson clover, subterranean clover, and hairy vetch over the winter months under natural conditions. Aldicarb applied in the seed furrow at cotton planting subsequent to cover crop termination, decreased R. reniformis population densities for 90 days after planting compared to the untreated control. Seed cotton yields were not affected by the cover crop but increased an average of 20% in all plots treated with aldicarb. Although crimson clover, subterranean clover, and hairy vetch were shown to be hosts of R. reniformis in greenhouse tests, the populations did not increase on these cover crops under the natural environmental conditions of the field and microplot tests.

A total of 101 soil and root samples containing mixed populations of 10 genera and 11 species belonging to 7 families of the order Tylenchida were analyzed. Lesion (Pratylenchus thornei), spiral (Helicotylenchus sp.) and cyst forming (Heterodera cruciferae and Heterodera mediterranea) nematodes were the most frequently encountered nematode plant pests. Cyst forming nematodes were detected in 45 (45%) soil samples collected from 101 cabbage fields. The majority of these samples 78% (35) were infested with Heterodera cruciferae and 20% (9) with H. mediterranea and a single sample had a mixed population of both H. mediterranea and H. cruciferae. This survey yielded the first report of H. mediterranea in Turkey and the first record of white and red head cabbages being hosts for this and two lesion nematodes (Pratylenchus thornei and P. neglectus).

Isolation of these relationships is important because shifts in lumber production reflect changes in harvesting activity. In turn, harvesting influences long-term forest composition and structure. We define three hardwood regions in Pennsylvania based on forest composition and present a chronology of regional changes in saw timber volumes, sawtimber composition, and lumber production. Regional changes in hardwood lumber production were found to be positively related to changes in the price of No. 1 Common lumber adjusted for changes in forest composition between 1970 and 1999. This finding supports our contention that regional changes in lumber production are influenced by a combination of changes in interspecies lumber price and changes in species availability.

An inventory of beech bark disease conditions in three stands in 2004 showed that an older, uneven-aged stand managed by individual tree selection for 50 years had over 70% of the basal area in clean- (or disease-free) and rough-barked trees-trees that showed resistance or partial resistance to the disease; 15% of the basal area was clean. In contrast, an adjacent essentially unmanaged stand had well over 60% of the basal area in Nectria-damaged trees-those with sunken bark because of cambial mortality. A young unmanaged stand had a little over 60% of the basal area in mostly rough-barked trees. Records indicate that the amount of beech was not reduced by the disease in any of the inventoried stands. Apparently, single-tree selection over a 50-year period has substantially improved the disease resistance and merchantable potential of the stand.

We tested a control method for introduced Norway rats on Kiska Island, Alaska, during April-May, 2004, by hand-broadcasting rodenticide pellets (0.005% diaphacinone) over a 4-ha area at the rate of 28 kg/ha. We also gathered data on aspects of rat ecology and distribution, although rats were difficult to detect and capture. The rodenticide bait pellets seemed to have been effective in reducing the Norway rat population, however, this is based on a limited observation of rat sign and captures. Four rats were captured on elevational transects on the northside of the island, all below 20 m elevation. Twelve rats captured in other aspects of the study also came from lower elevations. Rat stomach contents revealed that vegetation and seabirds were important components of the diet at the north end of Kiska Island, but stomach contents varied by location depending upon the type of food most readily available. All eight females captured were pregnant and bore an average of 10 embryos. Although the control or eradication of rats at remote locations such as the Aleutian Islands is theoretically possible, there are many challenges posed to resource managers. This field study has provided insight into the ecology and management of Norway rats at Kiska Island, but also points out some of the challenges that remain.

We quantified diversity patterns in understory vascular plant species, including exotic plant species, across four broad age classes of low-elevation coniferous forests of the western Olympic Peninsula, Washington, USA-regeneration (age 0-19 years), young (20-79 years), mature (80-199 years) and late-seral (>= 200 years). Species richness varied significantly with age class: highest in newly regenerating stands, lowest in the young class, and increasing to the late-seral stage. We observed an age-class effect for total percent cover by growth form and for distribution of exotic plant species. Shrubs had highest cover in the regeneration category; forbs and sub-shrubs had highest cover in late-seral forest. Ferns and graminoids did not vary across age classes. Twenty percent of the species found in regeneration plots were exotic, while all species encountered in late-seral plots were native. The proportion of exotic species was intermediate in young (7%) and mature (6%) forests. On the western Olympic Peninsula the late-seral age class is the most limited in spatial extent and has the least connectivity across ownerships. Management efforts aimed at conservation of late-seral plant species at broad spatial scales will need to consider the lack of contiguity of late-seral forest and the role of ownership in its distribution.

Traditionally, studies of phenotypic trade-offs involving dispersal focus on resource allocation differences between flight and reproduction. However, investments in dispersal may also result in reduced allocation to other "third-party traits" (e.g. compensatory feeding) that are not directly associated with reproduction. Such traits remain largely uninvestigated for any phytophagous insect despite their importance for performance and survival. Using two wing-dimorphic, phloem-feeding planthoppers, Prokelisia dolus and Prokelisia marginata that differ dramatically in dispersal abilities, we sought evidence for a trade-off between investments in dispersal (flight apparatus) and ingestion capability (allocation to the esophageal musculature governing ingestion). Dispersal allows species to meet nutrient demands by moving to higher-quality resources. In contrast, enhanced investment in esophageal musculature increases ingestion capacity and allows phloem feeders to compensate for deteriorating plant nutrition on site. Our objectives were to compare differences in flight and feeding investment between P. dolus and P. marginata and between the wing forms of both species, and to compare ingestion capacity between the two species and wing forms. Morphometric and gravimetric measures of investment in flight versus feeding indicate that the sedentary P. dolus allocates more muscle mass to feeding whereas P. marginata invests more heavily in flight. Likewise, brachypters invest more in feeding and C1 Univ Maryland, Dept Entomol, College Pk, MD 20742 USA.

We hypothesized that short dry spells during the wet season are a significant source of mortality for the newly emerging seedlings of pioneer species that recruit in treefall gaps in tropical forests. An analysis of a 49-year rainfall record for three forests across a rainfall gradient in central Panama confirmed that dry spells of >= 10 days during the wet season occur on average once a year in a deciduous forest, and once every other year in a semi-deciduous moist and an evergreen wet forest. The effect of wet season dry spells on the recruitment of pioneers was investigated by comparing seedling survival in rain-protected dry plots and irrigated control plots in four large artificially created treefall gaps in a semi-deciduous tropical forest. In rain-protected plots surface soil layers dried rapidly, leading to a strong gradient in water potential within the upper 10 cm of soil. Seedling survival for six pioneer species was significantly lower in rain-protected than in irrigated control plots after only 4 days. The strength of the irrigation effect differed among species, and first became apparent 3-10 days after treatments started. Root allocation patterns were significantly, or marginally significantly, different between species and between two groups of larger and smaller seeded species. However, they were not correlated with seedling drought sensitivity, suggesting allocation is not a key trait for drought sensitivity in pioneer seedlings. Our data provide strong evidence that short dry spells in the wet season differentially affect seedling survivorship of pioneer species, and may therefore have important implications to seedling demography and community dynamics.

TI Tree-girdling to separate root and heterotrophic respiration in two Eucalyptus stands in Brazil SO OECOLOGIA LA English DT Article DE belowground production; net ecosystem production; tropical forest plantation ID SOIL RESPIRATION; CARBON ALLOCATION; DECIDUOUS FOREST; ECOSYSTEM; DIOXIDE; DECLINE; GROWTH; AGE AB The release of carbon as CO(2) from belowground processes accounts for about 70% of total ecosystem respiration. Insights about factors controlling soil CO(2) efflux are constrained by the challenge of apportioning sources of CO(2) between autotrophic tree roots (and mycorrhizal fungi) and heterotrophic microorganisms. In some temperate conifer forests, the reduction in soil CO(2) efflux after girdling (phloem removal) has been used to separate these sources. Girdling stops the flow of carbohydrates to the belowground portion of the ecosystem, which should slow respiration by roots and mycorrhizae while heterotrophic respiration should remain constant or be enhanced by the decomposition of newly dead roots. Therefore, the reduction in CO(2) efflux after girdling should be a conservative estimate of the belowground flux of C from trees. We tested this approach in two tropical Eucalyptus plantations. Tree canopies remained intact for more than 3 months after girdling, showing no reduction in light interception. The reduction in soil CO(2) efflux averaged 16-24% for the 3-month period after girdling. The reduction in CO(2) efflux was similar for plots with one half of the trees girdled and those with all of the trees girdled. Girdling did not reduce live fine root biomass for at least 5 months after treatment, indicating that large reserves of carbohydrates in the root systems of Eucalyptus trees maintained the roots and root respiration. Our results suggest that the girdling approach is unlikely to provide useful insights into the contribution of tree roots and heterotrophs to soil CO(2) efflux in this type of forest ecosystem.

Soil respiration is the second largest flux of carbon (C) in these ecosystems, and the objective of this study was to understand how soil respiration responded to the experimental treatments as these fast-growing stands of pure aspen and birch + aspen approached maximum leaf area. Rates of soil respiration were typically lowest in the elevated O-3 treatment. Elevated CO2 significantly stimulated soil respiration (8-26%) compared to the control treatment in both community types over all three growing seasons. In years 6-7 of the experiment, the greatest rates of soil respiration occurred in the interaction treatment (CO2 + O-3), and rates of soil respiration were 15-25% greater in this treatment than in the elevated CO2 treatment, depending on year and community type. Two of the treatments, elevated CO2 and elevated CO2 + O-3, were fumigated with C-13-depleted CO2, and in these two treatments we used standard isotope mixing models to understand the proportions of new and old C in soil respiration. During the peak of the growing season, C fixed since the initiation of the experiment in 1998 (new C) accounted for 60-80% of total soil respiration. The isotope measurements independently confirmed that more new C was respired from the interaction treatment compared to the elevated CO2 treatment. A period of low soil moisture late in the 2003 growing season resulted in soil respiration with an isotopic signature 4-6 parts per thousand enriched in 13 stopC compared to sample dates when the percentage soil moisture was higher. In 2004, an extended period of low soil moisture during August and early September, punctuated by a significant rainfall event, resulted in soil respiration that was temporarily 4-6 parts per thousand more depleted in C-13. Up to 50% of the Earth's forests will see elevated concentrations of both CO2 and O-3 in the coming decades and these interacting atmospheric trace gases stimulated soil respiration in this study.

Here we propose a mechanistic approach to understanding how the relative importance of these sources of density dependence can change over ontogeny through changes in dispersal abilities, energy stores and mortality risks. Whereas the potential for active dispersal typically increases over ontogeny as a function of body size, susceptibility to starvation and predation decreases. The joint effect of these mechanisms suggests a general model for the ontogenetic sequence of how density dependence is manifested, with density dependence early in ontogeny being primarily expressed as mortality on local spatial scales, whereas later stages respond to local density in terms of dispersal and potentially growth. Here we test this model by manipulating the densities of juvenile Atlantic salmon (Salmo salar L.) at two life-history stages in the wild. Density-dependent mortality during the early juvenile stage (i.e. fry at onset of exogenous feeding) was accompanied by no effects on body size and weak effects on dispersal. In contrast, dispersal of older juveniles (i.e. parr 2-3 months after onset of feeding) was strongly density-dependent, with more individuals emigrating from high-density release sites, and with no effect of initial density on mortality. This dispersal, however, appeared insufficient to produce an ideal free distribution within the study stream, as indicated by the effect of spatial variation in density on body size by the end of the first growth season. These results demonstrate that the way density-dependent effects are partitioned amongst survival, growth and dispersal changes throughout ontogeny. Furthermore, these changes occur in correlation with changes in individual mortality risks and dispersal abilities, and suggest a general paradigm for the way in which juvenile density-dependence is manifest in spatially structured populations of highly fecund organisms.

The utility of phylogenomics is growing with the increase in the number and diversity of taxa for which whole genome and large transcriptome sequence sets are being generated. We assert that the synergy between genomic and phylogenetic perspectives in comparative biology would be enhanced by the development and refinement of minimal reporting standards for phylogenetic analyses. Encouraged by the development of the Minimum Information About a Microarray Experiment (MIAME) standard, we propose a similar roadmap for the development of a Minimal Information About a Phylogenetic Analysis (MIAPA) standard. Key in the successful development and implementation of such a standard will be broad participation by developers of phylogenetic analysis software, phylogenetic database developers, practitioners of phylogenomics, and journal editors.

Despite a potential role of vitamin K in bone, little is known about the effects of altered dietary phylloquinone intake on the underlying components of bone and mineral metabolism. Methods: A 84-day in-house dietary phylloquinone (vitamin K) depletion-repletion study was undertaken in 21 postmenopausal women (mean age: 70 years) to assess the effects of altered vitamin K status on intestinal calcium (Ca) absorption, urinary and serum Ca and phosphorus (P), serum calcemic hormones, and serum biomarkers of bone turnover [osteocalcin and N-telopeptide type 1 collagen cross-links (NTx)] and the response to 1,25-dihydroxyvitamin D treatment (1 mu g/dayx7 d). Results: The group receiving calcitriol treatment (n=11) had higher Ca absorption, urinary Ca, urinary and serum P and serum osteocalcin and lower serum parathyroid hormone (PTH).There were no significant effects of acute (4-week) phylloquinone depletion on response to 1,25-dihydroxyvitamin D treatment or on measures of bone formation or mineral metabolism. However, phylloquinone treatment had a significant effect (p < 0.04) on serum NTx. Phylloquinone repletion, up to five times (450 mu g phylloquinone per day) the currently recommended adequate intake level of dietary phylloquinone for women, significantly reduced serum NTx (16.8 +/- 0.9 nmol bone collagen equivalents (BCE) per liter following repletion vs 18.4 +/- 1.1 nmol BCE per liter following depletion; p < 0.01). Conclusions: These findings suggest that altering vitamin K status in postmenopausal women by manipulating phylloquinone intake does not have an acute affect on intestinal Ca absorption, renal mineral excretion, or bone formation, but high phylloquinone intake may modestly reduce bone resorption. The impact of high phylloquinone intake on bone mineral density and fracture risk needs to be ascertained in randomized clinical trials.

Currently, the majority of the predicted Caenorhabditis elegans GPCRs are orphan. Here, we describe the characterization of such an orphan C. elegans GPCR, which is categorized in the tachykinin-like group of receptors. Since the C. elegans genome predicts only one tachykinin-like peptide (SFDRMGGTEFGLM), which could not activate the receptor, we hypothesized that one or some of the numerous FMRFamide related peptides (FaRPs) could be the cognate ligands for this receptor. This hypothesis was based on the suggestion that RFamides maybe ancestral neuropeptides, from which a lot of the amidated neuropeptides, including tachykinins, derived. Indeed, we found that the orphan receptor encoded by the Y59H11AL.1 gene is activated by several C. elegans neuropeptides, including SPMERSAMVRFamide. These peptides activate the receptor in a concentration-dependent way. (c) 2005 Elsevier Inc. All rights reserved. C1 Katholieke Univ Leuven, Lab Dev Physiol Genom & Proteom, B-3000 Louvain, Belgium.

The objective of this laboratory experiment was to compare the mineralisation of atrazine and metolachlor with that of their respective metabolites in VFS and cultivated soil. With the exception of total bacteria, propagule density of the microbial groups, endogenous soil enzymes and microbial diversity were higher in the VFS soil. This correlated with increased mineralisation of metolachlor and its metabolites in the VFS soil and indicates potential for VFS to curtail the subsequent transport of these compounds. In contrast, the mineralisation of atrazine and the majority of its metabolites was substantially reduced in VFS soil relative to cultivated soil. Consequently, the potential for subsequent transport of atrazine and many of its metabolites may be greater in VFS soil than in cultivated soil if reduced mineralisation is not offset by increased sorption in the VFS.

All beetles initiating flight along the pheromone plume make contact with the pheromone source. Analysis of digitized flight tracks indicates that C. maculatus males respond similarly to moths tested at several wind speeds. Beetles' mean net upwind speeds and speeds along their track are similar (P > 0.05) across wind speeds, whereas airspeeds increase (P < 0.01) with increasing wind speed. Beetles adjust their course angles to fly more directly upwind in higher wind speeds, whereas track angles are almost identical at each wind speed. The zigzag flight paths are generally narrow compared with most moth flight tracks and interturn distances are similar (P > 0.05) at the wind speeds employed. The frequency of these counterturns across the wind line is almost constant regardless of wind speed, and there is little variation between individuals. The upwind flight tracks are more directly upwind than those typically seen for male moths flying upwind toward sex pheromone sources. Male moths typically produce a bimodal distribution of track angles to the left and right of the windline, whereas C. maculatus males' track angles are centred about 0 degrees. Preliminary examination of two other beetle species indicates that they fly upwind in a similar fashion. C1 USDA ARS, Crop Protect & Qual, Parlier, CA 93648 USA.

Glass tubes are provided as nesting cavities to allow the in-nest behaviour of bees to be observed. In addition, each glass tube is cut into three sections for experimental manipulation and for subsequent chemical analysis. Nesting females drag their abdomen along the tube before exiting, spiral inside the tube, and sometimes deposit fluid droplets from the tip of the abdomen. For the manipulation, the outer section, the middle section, or both sections are removed and replaced with similar clean glass tube sections, and the behaviour exhibited by test females is recorded upon arrival in front of the nesting site and inside the nesting tubes. The resulting hesitation behaviour displayed by females after treatments appears to indicate the loss of some olfactory cues used for nest recognition inside the entire nest. Chemical analysis of the depositions inside the nesting tube, as well as analysis of the cuticular lipids of the nesting bees, reveals the presence of free fatty acids, hydrocarbons and wax esters.

Conjugated fatty acids, which are synthesized from phosphatidyleholine (PC)-linked substrates, accumulated in PC and phosphatidylethanolamine, and relative amounts of these fatty acids were higher in PC than in triacylglycerol (TAG) in the transgenic seeds. The highest relative amounts of conjugated fatty acids were detected in PC from seeds of soybean and A. thaliana that expressed the C officinalis and M. charantia conjugases, where they accounted for nearly 25% of the fatty acids of this lipid class. In these seeds, > 85% of the conjugated fatty acids in PC were detected in the sn-2 position, and these fatty acids were also enriched in the sn-2 position of TAG. In marked contrast to the transgenic seeds, conjugated fatty acids composed < 1.5% of the fatty acids in PC from seeds of five unrelated species that naturally synthesize a variety of conjugated fatty acid isomers, including seeds that accumulate conjugated fatty acids to > 80% of the total fatty acids. These results suggest that soybean and A. thaliana seeds are deficient in their metabolic capacity to selectively catalyze the flux of conjugated fatty acids from their site of synthesis on PC to storage in TAG.

BOTRYTIS; ARABIDOPSIS; PLANTS; CHROMOPLASTS; TOBACCO; LEAVES AB The cauliflower (Brassica oleracea L. var. botrytis) Or gene is a rare carotenoid gene mutation that confers a high level of P-carotene accumulation in various tissues of the plant, turning them orange. To investigate the biochemical basis of Or-induced carotenogenesis, we examined the carotenoid biosynthesis by evaluating phytoene accumulation in the presence of norflurazon, an effective inhibitor of phytoene desaturase. Calli were generated from young seedlings of wild type and Or mutant plants. While the calli derived from wild type seedlings showed a pate green color, the calli derived from Or seedlings exhibited intense orange color, showing the Or mutant phenotype. Concomitantly, the Or calli accumulated significantly more carotenoids than the wild type controls. Upon treatment with norflurazon, both the wild type and Or calli synthesized significant amounts of phytoene. The phytoene accumulated at comparable levels and no major differences in carotenogenic gene expression were observed between the wild type and Or calli. These results suggest that Or-induced beta-carotene accumulation does not result from an increased capacity of carotenoid biosynthesis. (c) 2006 Elsevier Ltd. All rights reserved.

The complete structural elucidation of all isolated compounds was achieved by 1D/2D NMR spectroscopy and HPLC-MS in combination with methylation analysis. The absolute configuration of the carbohydrate constituents was determined by chiral GC after acidic hydrolysis and trifluoroacetylation.

The isolated trisaccharide alpha-L-galactopyranosyl-(1 -> 2)-beta-D-Xylopyranosyl-(1 -> 2)5-O-trans-feruloyl-L-arabinofuranose (FAXG) contributes to the complexity of heteroxylan side-chains from maize bran and 5-O-trans-p-coumaroyl-L-arabinofuranose represents the first p-coumaroylated heteroxylan side-chain isolated from cereal grains. Complex feruloylated heteroxylan side-chains are possibly, like ferulate cross-linking of the heteroxylans and binding of heteroxylans to lignin, a factor contributing to limited enzymatic degradation of fibre.

To investigate pathways of entry. field-grown plants were sprayed with macroconidial inoculum after heads emerged from the flag leaf sheath and then were mist irrigated daily in the morning and evening. On selected days, 1 to 8 days after inoculation (DAI), 80 to 190 florets per day were harvested, dissected, and examined for presence and location of mycelial colonies. At 1 to 12 DAI, 57 to 100 florets likewise were examined for lesions. Patterns of colonization indicated that the fungus entered florets principally through crevices between the overlapping lemma and palea or through the apical floret mouth. The crevices were open for entry until approximate to 8 days after heads emerged. Most florets had mycelial colonies on the external Surface in a Sheltered pocket near the base of the ventral furrow of the palea. Mycelia spread laterally from the furrow to the crevice between lemma and palea. Anther colonization had only a minor role in invasion of florets. Hyphal penetration of stomates was not seen. Lesions usually developed first within 3 mm of the floret apex or 3 mm of the floret base. Within florets. lesions often were Contiguous between lemma and palea, palea and caryopsis, or in all three floret parts. However, lesions in the caryopsis developed later and were fewer in number than in the lemma and palea and always were associated with lesions in the palea. The results show the importance of initial mycelial colonization of floret outer surfaces, pathways of entry via lemma or palea crevices or floret mouth, and spread of lesions within the floret at interfaces between lemma, palea, and caryopsis.

A. flavus can be divided into the S and L strains, of which the S-strain isolates, on average. produce greater quantities of aflatoxins than the L-strain isolates. Aflatoxin contamination can be severe in several crops in South Texas. The Structure of A. flavus communities residing in soils of South Texas was determined from 326 soil samples collected from 152 fields located from the Rio Grande Valley in the South to Fort Bend County in the north from 2001 through 2003. Analysis of variance indicated significant differences in the incidence of A. flavus isolates belonging to the S strain (percent S) among regions. The Coastal Bend (30.7%) and Upper Coast (25.5%) regions had significantly higher percent S incidence than the Rio Grande Valley (4.8%). No significant differences in percent S among years were detected. The CFU per gram of soil were not significantly different among regions. Strain S incidence was positively correlated With clay content and negatively correlated with sand content. Fields cropped to cotton the previous year had a higher S-strain incidence, whereas fields cropped to corn had greater total quantities of A. flavus propagules. Maps of S-strain patterns show that the S strain constitutes > 30% of the overall A. flavus community in the area extending from the central Coastal Bend region to the central Upper Coast region. The west Rio Grande Valley had the lowest S-strain incidence (< 10%). Geographic variation in S-strain incidence may influence the distribution of aflatoxin contamination in South Texas.

Given the large number of pathogens that could be introduced, development of rapid detection methods and control strategies for every potential agent would be extremely difficult and costly. Thus, to ensure the most effective direction of resources a list of high-threat pathogens is needed. We address development of a pathogen threat assessment model based on the analytic hierarchy process (AHP) that can be applied worldwide, using the United States as an illustrative example. Previously, the AHP has been shown to work well for strategic planning and risk assessment. Using the collective knowledge of subject matter expert panels incorporated into commercial decision-making software. 17 biological and economic criteria were determined and given weights for assessing the threat of accidental or deliberately introduced pathogens. The rating model can be applied by experts on particular crops to develop threat lists, especially those of high priority, based on the current knowledge of individual diseases.

However, high variability is inherent in this type of enumeration and counts may not be representative of the pathogenic population of Pythium spp. Variable regions of the internal of transcribed spacer of the rDNA were used to design species-specific pruners for detection and quantification of nine Pythium spp. from soils in eastern Washington. Primer pairs were designed for Pythium abappres-sorium, P. attrantheridium, P. heterothallicum, P. irregulare group I, P. irregulare group IV, P. paroecandrum, P. rostratifingens. P. sylvaticum. and P. ultimum and used with real-time polymerase chain reaction. Standard curves were generated for each of the species using SYBR Green I fluorescent dye for detection of amplification. Seventy-seven isolates of Pythium were screened to confirm specificity of each pruner set. DNA was extracted front soil and standard curves were generated for P. irregulare group I, P irregulare group IV, and P. ultimum to correlate Populations of each species in the soil with quantities of DNA amplified from the same soil. Examination of raw field soils revealed results similar to those observed in previous Studies. This new technique for the quantification of Pythium spp. is rapid and accurate. and will he it useful tool in the future Study of these pathogenic Pythium spp. C1 Washington State Univ, USDA ARS, Root Dis & Biol Control Unit, Pullman, WA 99164 USA.

In order to determine whether binding to other cellular proteins is affected similarly, far-Western overlays of extracts prepared from light- or dark-treated spinach (Spinacia oleracea) leaves were performed using digoxigenin (DIG)-labeled Arabidopsis 14-3-3 omega. When separated by SDS-PAGE, approximately 25 proteins of > 35 kDa could be resolved that interacted with DIG-labeled 14-3-3 omega in the absence of added cations. The presence of 5 mM Mg2+ or 0.5 mM spermine enhanced binding to most of the target proteins to a maximum of about a doubling of the observed binding. In most cases, the binding was dependent on phosphorylation of the target protein, whereas that was not necessarily the case for binding to target proteins that were unaffected by polycations. The extent of stimulation varied among the target proteins, but there was no indication that the nature of the cation activator (e.g. Mg2+ vs. spermine(4+)) altered the specificity for target proteins. In addition, binding of DIG-labeled 14-3-3 omega to some, but not all, target proteins was reduced by 5 mM 5'-AMP. Interestingly, light/dark treatment of spinach leaves affected the subsequent binding of DIG-labeled 14-3-3 omega in the overlay assay to only a few of the target proteins, one of which was identified as NADH:nitrate reductase. Overall, the results suggest that the binding of 14-3-3s to targets in addition to pNR may also be regulated by polycations and 5'-AMP. C1 N Carolina State Univ, USDA ARS, Raleigh, NC 27695 USA.

To determine the inheritance of parthenocarpy in gynoecious cucumber, P-1, P-2, F-1, F-2, BC1P1, and BC1P2 generations derived from crossing two non-parthenocarpic gynoecious inbred lines [Gy8 (P-2; processing type) and 'Marketmore 80' (P-2; MM, fresh market type)] with a highly parthenocarpic inbred line [2A (P-1; processing type)] were evaluated for fruit number in a greenhouse at Arlington, Wisc. in 1999 (designated 2A x Gy8 1999) and in the open-field at Hancock, Wisc. in 2000 (designated 2A x Gy8 2000 and 2A x MM 2000). There were significant location and location x generation interaction effects, and therefore generation means analyses were conducted separately for each location. The minimum numbers of effective factors controlling parthenocarpy were estimated to be at least one (2A x Gy8 1999), two (2A x Gy8 2000) and four (2A x MM 2000). Results suggest that selection for parthenocarpy for multiple hand harvest operations will likely be more effective than that for once-over machine harvest operations. However, the selection efficiency will likely vary across different populations and environments. C1 Univ Wisconsin, Dept Hort, Madison, WI 53706 USA.

However, the genomic locations of factors controlling parthenocarpic fruit development in this species are not known. Therefore, an F-2 : 3 mating design was utilized to map quantitative trait loci (QTL) for parthenocarpy using a narrow cross employing two gynoecious, indeterminate and normal leaf lines [2A (parthenocarpic) and Gy8 (non-parthenocarpic)]. QTL detection was performed employing 2A- and Gy8-coupling phase data using the parthenocarpic yield of 126 F-3 families grown at two locations at Hancock, WI in 2000. The QTLs detected in this study were compared with the map locations of QTLs conditioning first-harvest yield of seeded cucumber characterized in a previous study. There were 10 QTLs for parthenocarpy detected defining four genomic regions, in which three QTLs also mapped to the same genomic regions as QTLs detected for fruit yield at first-harvest as reported in a previous study. The eight fluorescence amplified fragment length polymorphism (AFLP) markers linked to parthenocarpy through QTL mapping defined herein (four each in linkage groups 1 and 4) are candidates for use in marker-assisted selection programmes where breeding for increased levels of parthenocarpy is an objective in the elite-processing cucumber populations.

(squash, pumpkin) is a highly polymorphic vegetable species of major importance. Our study characterized a spectrum of C. pepo germplasm for the ability to regenerate in vitro by direct organogenesis from cotyledon explants. Cultivars tested included both cultivated subspecies, texana and pepo, and nearly all of their respective cultivar-groups. Direct shoot regeneration occurred in all accessions, and was generally high (56-94%), with a single exception of 22% ('Bolognese'). There was no significant difference between the percentage regeneration of the two subspecies. Shoot regeneration per responding explant was uniform (1.2-1.6 shoots per explant). Only 'True French' produced statistically more shoots (3.9 per explant) than other accessions. The morphology of regeneration varied. Most cultivars produced long shoots, often fasciated, amid a few small buds. Some subspecies pepo cultivars (Beirut, Yugoslavia 7, Ma'yan and True French) produced short, massive, hollow shoots, sometimes accompanied by shoots that were more normal. Two subspecies texana cultivars (Creamy Straightneck and Small Bicolor) produced single (sometimes double) shoots without other buds. The production of chimeric (mixoploid) regenerants varied and there was a tendency to regenerate chimeric plants from the widest-fruited accessions (i.e. lowest length-to-width ratio) in each subspecies. Subspecies pepo Pumpkin Group 'Tondo di Nizza' showed significantly greater production of chimeric regenerants. In comparison with the great range of variation observed in fruit shape, the variation of in vitro responses (mostly less than 2-fold in regeneration and shoot production) was less than expected.

Since little soybean rust resistance is known, and resistance is often difficult to detect or quantitate, we initiated a project to develop a better, more quantitative, method. The methodology determined the average numbers and diameters of uredinia in lesions that developed on leaves of inoculated plants 14 days after inoculation. It was used to compare virulence of P pachyrhizi isolates from Asia and Australia and P meibomiae from Puerto Rico and Brazil, collected as many as 30 years earlier, with isolates of P. pachyrhizi recently collected from Africa or South America. Susceptible reactions to P. pachyrhizi resulted in tan-colored lesions containing 1 to 14 uredinia varying greatly in size within individual lesions. In contrast, on these same genotypes at the same time of year, resistance to other P pachyrhizi isolates was typified by 0 to 6 small uredinia in reddish-brown to dark-brown lesions. Using appropriate rust resistant and rust susceptible genotypes as standards, examination of uredinia 14 days after inoculation allowed quantitative comparisons of sporulation capacities, one measure of susceptibility or resistance to soybean rust. The study verified the presence and ability to detect all known major genes for resistance to soybean rust in the original sources of resistance. It demonstrated that soybean lines derived from the original PI sources, and presumed to possess the resistance genes, in actuality may lack the gene or express an intermediate reaction to the rust pathogen. We suggest that a determination of numbers and sizes of uredinia will detect both major gene and partial resistance to soybean rust.

Although TBZ is not used before harvest, another benzimidazole, thiophanate methyl, is commonly used in Florida and may be introduced soon in California to control postharvest decay of citrus fruit. Isolates from infected lemons and oranges were collected from many geographically diverse locations in California. Thirty-five isolates collected from commercial groves and residential trees were sensitive to TBZ, while 19 of 74 isolates collected from 10 packinghouses were resistant to TBZ. Random amplified polymorphic DNA analysis indicated that the isolates were genetically distinct and differed from each other. Nineteen TBZ-resistant isolates and a known TBZ-resistant isolate displayed a point mutation in the P-tubulin gene sequence corresponding to amino acid codon position 200. Thymine was replaced by adenine (TTC -> TAC), which changed the phenylalanine (F) to tyrosine (Y). In contrast, for 49 TBZ-sensitive isolates that were sequenced, no mutations at this or any other codon positions were found. All of the isolates of P. digitatum resistant to TBZ collected from a geographically diverse sample of California packinghouses appeared to have the same point mutation conferring thiabendazole resistance.

ToCV can cause a decline in plant vigor and reduce fruit yield. It is emerging as a serious production problem for field and greenhouse tomato growers, and has been increasing in prevalence in many parts of the world. The virus is unique among known whitefly-transmitted viruses, due to its ability to be transmitted by four whitefly vectors from two genera. Studies demonstrated that transmission efficiency and virus persistence in the vector varies significantly among the different whitefly vectors. Trialeurodes abutilonea and Bemisia tabaci biotype B are highly efficient vectors of ToCV. B. tabaci biotype A and T vaporariorum are less efficient vectors, but are fully capable of transmission. ToCV persists for up to 5 days in T abutilonea, 2 days in B. tabaci biotype B, and only 1 day in B. tabaci biotype A and T vaporariorum. ToCV has a moderately wide host range, infecting 24 host plant species in seven families. A portion of the coat protein coding region of five geographically diverse ToCV isolates was compared and found to be highly conserved. This information, coupled with existing information on conservation within the heat shock protein 70 homologue coding region, suggests that many ToCV isolates throughout the world are related very closely, and may have been distributed on plant material.

Phenotypic diversity was assessed using mating type and metalaxyl resistance; genotypic diversity was assessed using two allozyme loci (glucose-6-phosphate isomerase, Gpi, and peptidase, Pep), mitochondrial DNA haplotype and the multilocus RFLP probe RG57. All isolates were A1 mating type and Gpi 100/100. The majority were Pep 100/100, but four Pep 83/100 and six Pep 96/100 isolates were identified. Three mtDNA haplotypes were detected; haplotype IIa was the most common, but each year up to 2001 its frequency declined, with a concomitant increase in Ia isolates. Three isolates had the rare haplotype IIb, but this was only detected in 1998. Metalaxyl resistance and mtDNA haplotype were markedly associated: most haplotype Ia isolates were metalaxyl-resistant, whereas haplotype IIa was more commonly associated with metalaxyl sensitivity. Analysis of a subsample of 91 isolates revealed nine RG57 genotypes, three associated exclusively with haplotype IIa and six exclusively with haplotype Ia. The most common RG57 genotype (51% of isolates) comprised both metalaxyl-resistant and -sensitive haplotype IIa isolates. However, of haplotype Ia isolates, all metalaxyl-resistant phenotypes belonged to one of four RG57 types, one of which was the second most frequent overall (29% of isolates), while all metalaxyl-sensitive isolates belonged to one of two other types. The P. infestans population in Northern Ireland appears to consist of a limited number of clones related to, but differentiated from, the populations in mainland Britain and elsewhere in Europe.

The number of colony-forming units (CFU) of A. flavus on the cottonseed, and the percentage of S strain (%S) were both correlated with aflatoxin contamination of cottonseed. The number of CFU differed between both regions and seasons, while %S differed only between regions. Comparison of maps of CFU and %S revealed that CFU shows a higher variation across years, while %S shows higher spatial variation. The Rio Grande Valley had significantly lower CFU and %S strain than the Coastal Bend and Upper Coast regions. Cottonseed produced in 1999 had significantly more A. flavus than that produced in either 2000 or 2001. Identification of factors dictating geographical variation in S-strain incidence may provide insights that will lead to improved aflatoxin management. C1 USDA ARS, Tucson, AZ 85721 USA.

TI Phosphorus and aluminum interactions in soybean in relation to aluminum tolerance, exudation of specific organic acids from different regions of the intact root system SO PLANT PHYSIOLOGY LA English DT Article ID CONTRASTING SOIL TYPES; TRITICUM-AESTIVUM L; ZEA-MAYS L; CITRIC-ACID; GENETIC-VARIATION; GLYCINE-MAX; HIGH-LEVEL; RESISTANCE; EFFICIENCY; WHEAT AB Aluminum (Al) toxicity and phosphorus (P) deficiency often coexist in acid soils that severely limit crop growth and production, including soybean (Glycine max). Understanding the physiological mechanisms relating to plant Al and P interactions should help facilitate the development of more Al-tolerant and/or P-efficient crops. In this study, both homogeneous and heterogeneous nutrient solution experiments were conducted to study the effects of Al and P interactions on soybean root growth and root organic acid exudation. In the homogenous solution experiments with a uniform Al and P distribution in the bulk solution, P addition significantly increased Al tolerance in four soybean genotypes differing in P efficiency. The two P-efficient genotypes appeared to be more Al tolerant than the two P-inefficient genotypes under these high-P conditions. Analysis of root exudates indicated Al toxicity induced citrate exudation, P deficiency triggered oxalate exudation, and malate release was induced by both treatments. To more closely mimic low-P acid soils where P deficiency and Al toxicity are often much greater in the lower soil horizons, a divided root chamber/nutrient solution approach was employed to impose elevated P conditions in the simulated upper soil horizon, and Al toxicity/P deficiency in the lower horizon. Under these conditions, we found that the two P-efficient genotypes were more Al tolerant during the early stages of the experiment than the P-inefficient lines. Although the same three organic acids were exuded by roots in the divided chamber experiments, their exudation patterns were different from those in the homogeneous solution system. The two P-efficient genotypes secreted more malate from the taproot tip, suggesting that improved P nutrition may enhance exudation of organic acids in the root regions dealing with the greatest Al toxicity, thus enhancing Al tolerance. These findings demonstrate that P efficiency may play a role in Al tolerance in soybean. Phosphorus-efficient genotypes may be able to enhance Al tolerance not only through direct Al-P interactions but also through indirect interactions associated with stimulated exudation of different Al-chelating organic acids in specific roots and root regions.

In large part, past research has focused on interactions between phloem-feeding insects and their annual host plants with little emphasis on xylem-feeders or woody perennials-especially fruit trees. Using nylon filter cDNA arrays, we analyzed the transcriptional changes of 1731 non-redundant citrus transcripts that resulted from herbivory by a xylem-feeding leafhopper, the glassy-winged sharpshooter (GWSS), Homalodisca coagulata (Say) (Hemiptera: Cicadellidae). In addition, herbivory-elicited changes were compared to those of mechanical damage to better identify GWSS-specific responses. GWSS feeding led to a significant expression change in 50 transcripts. Of these, 14 were also changed by mechanical damage; however, the magnitude was in many cases reduced, suggesting transcriptional modification by GWSS-derived elicitors. Sequence similarity searches with the public database GenBank indicated that the responsive transcripts broadly function in direct defense, defense signaling, ROS scavenging, transport, cell wall modification, photosynthesis and abiotic stress. In particular, GWSS feeding resulted in a transcript profile that resembled wounding, likely through jasmonic acid-independent pathways, as well as an association with dehydration stress. In contrast to similar studies with aphids, salicylic acid-dependent pathogenesis-elated genes were weakly induced. Interestingly, six of the GWSS-responsive transcripts failed to significantly match any public protein sequence signifying their potential as novel genes functioning in plant defense, wound response or abiotic stress.

Effect of salinity on leaf gas exchange SO PLANT SCIENCE LA English DT Article DE cowpea; photosynthesis; salinity; salt tolerance; stomatal conductance; Vigna unguiculata ID STOMATAL CONDUCTANCE; SALT TOLERANCE; PLANTS AB In an effort to elucidate the physiological processes involved in cowpea differential growth response of four major USA cowpea cultivars (CB5, CB27, 85 17 and 7964) to increasing salinity, we investigated the effect of salinity on leaf gas exchange of net photosynthetic rate per unit leaf mass (Pnm) and per unit leaf area (Pna), and stomatal conductance (gs) of the four cowpea cultivars. The experiment was set up as a standard split-plot design in which cowpea plants were grown in greenhouse sand tanks irrigated with nutrient solutions. Seven salinities ranging from 2.6 to 20.5 dS m(-1) were constructed based on Colorado River water salt composition with NaCl, CaCl2 and MgSO4 as the salinization salts. Light-saturated Pnm, Pna and gs of fully expanded trifoliage were examined at the vegetative growth and flowering stages, and the data were analyzed using a split-plot analysis of variance (ANOVA) model. We found a highly significant (P <= 0.0001) reduction of Pnm, Pna and gs due to salinity. The responses of Pnm, Pna and gs to salinity could be further described by a general model of log(y) = a(1) + a(2)x + a(3)x(2), where y represents either Pnm, Pna, or gs; a(1), a(2) and a(3), empirical constants; x, salinity. We found that Pnm was more sensitive to salinity than Pna. Additionally, we found that increasing stomatal closure with increasing salinity might limit Pnm or Pna. While we did not find any significant difference (P > 0.05) of Pnm and Pna among the four cultivars, we did find a significant difference (P <= 0.05) in gs. No significant salt x cultivar interaction effect (P > 0.05) was found with Pnm, Pna and gs indicating that the four cowpea cultivars have the same response pattern of their leaf gas exchange to salinity.

System description and the effect on fruit quality of 'd' Anjou' pears SO POSTHARVEST BIOLOGY AND TECHNOLOGY LA English DT Article DE Pyrus communis; pear; packingline; hot-water; high-pressure; heat scald; friction discoloration; ripening ID BRUSHING TREATMENT; HEAT-TREATMENTS; STORAGE; DECAY; AIR; NECTARINES; REDUCTION; OXYGEN; RINSE AB A manually operated high-pressure hot-water washing system consisting of a boiler, hot-water mixing tank, contact loop, heat exchanger, spray mixing tank, high-pressure hot-water washing manifold, low-pressure fresh water rinse manifold, and pressure pump was constructed and installed in a packingline. The system developed 20-50 degrees C washing water at pressures up to 980 kPa. 'd'Anjou' pears (Pyrus communis L.), shortly after harvest, and after storage for 3 and 4 months in regular air (RA) or for 4, 7 and 8 months in controlled atmosphere (CA) at -1 degrees C were washed through the packingline with different wetting agents (0.1% Silwet, 0.01 and 0.1% Defoamer, and water), water pressures (regular and high-pressure (210-980 kPa)), water temperatures (control (tap water, 4-22 degrees C), 40 degrees C, and 50 degrees C), and brushes (soft and firm), respectively. The effect of the washing conditions on fruit quality was investigated after 1 month of storage at -1 degrees C to simulate shipping condition, and then again after 1 week at 20 C to simulate marketing condition. Hot-water caused severe heat scald. When nozzle temperature was 50 degrees C, the incidence of heat scald increased to over 50% for the fruit stored in RA for 3 months. Combined with hot-water. 540 kPa high-pressure washing increased the incidence of friction discoloration. There were lower incidences of friction discoloration and heat scald for fruit stored in CA for 7 months, in comparison to that in RA for 3 months. However, those fruit did not ripen properly as indicated by a high extractable juice content. Fruit washed at harvest had minor incidences of friction discoloration regardless of different brushes, water pressures, and wetting agents. Fruit washed after storages in either 4 months RA or 4 or 8 months CA suffered a high incidence of friction discoloration including scuffing symptoms and pressure marking. The firm brushes caused a higher incidence of friction discoloration mainly because of scuffing symptoms. However, no differences were found between different water pressures and wetting agents with respect to friction discoloration. Fruit stored for 4 months RA suffered 26-28% friction discoloration in comparison to 16-18% in CA stored fruit with firm brush washing. Extended CA storage increased friction discoloration even with soft brush washing. The results suggest that a washing system with high-pressure spray, < 30 degrees C warm water, wetting agent Defoamer and rotating soft brushes were significantly effective in removing surface pests and decay control without causing internal or external damage of fruit.

Spores were removed from the water system through dilution and also as a result of hot water in the system that was lethal to the spores. When the system was heated, viable spores were not detected after 2-4 h of operation. Reductions in decay in the HWP system were 36, 29, and 13% for Botrytis cinerea, Mucor piriformis, and P. expansum, respectively. The response of P. expansum appeared related to the length of time fruit was in cold storage. Heat injury was observed on fruit treated with 40 and 50 degrees C water but not on fruit at 30 degrees C nozzle temperature. The HWP system described in this study should be considered as a component of an integrated decay control strategy. (c) 2006 Elsevier B.V. All rights reserved.

Eliminating insects and mites on the packing line would be the last opportunity to provide for pest-free produce. In this study, an experimental packing line was used to evaluate techniques using different surfactant baths, pressurized water sprays, and styles of rotating brushes to remove field-collected and laboratory-reared grape mealybug. Pseudococcus maritimus (Ehrhorn) (Homoptera: Pseudococcidae), the diapausing two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae) and the woolly apple aphid, Eriosoma lanigerum (Hausman) (Homoptera: Aphididae). The organosilicone Silwet L-77 was no more effective than a silicone-based food grade defoamer in aiding removal. Mechanical methods, such as the style of rotating brushes and pressurized sprays, were significantly effective in removing surface arthropods. No improvement in removal occurred when pressure was increased beyond 420 kPa. These techniques can be easily adapted to commercial facilities and will reduce the incidence of surface arthropods on marketed fresh fruits. Published by Elsevier B.V.

Removal of mite and other arthropod eggs, such as European red mite (ERM) and codling moth (CM) eggs, may be enhanced by the use of a surface cleaning system, such as a hot water, high-pressure spray. Even if organosilicones, like Silwet L-77, have been used to kill spider mites, it was unclear if these chemicals could also facilitate the removal of arthropod eggs from the surface of fruit. In the present study, high-pressure washing process was highly effective in removing CM and ERM eggs at pressures as low as 400 kPa, resulting in greater than 60% removal of ERM eggs and 90% of CM eggs. High-pressure washing was the most important factor in removal of codling moth and European red mite eggs than organosilicone dips or hot water sprays. Published by Elsevier B.V.

Environmental conditions during storage and genetic factors both affect the extent of darkening during the storage period. The degree of pellicle color change of five distinct almond accessions was examined during long-term storage at 2, 22 and 32 degrees C. Pellicle luminosity, chroma and hue angle were measured on 12 dates throughout an 11-month storage period. An ANCOVA was used, with storage temperature being a covatiate, to examine the relative differences in luminosity, chroma and hue angle during the storage progression. A comparison of weighted simple linear regression equations was used to distinguish between different rates of pellicle color coordinate degradation during the storage period. When averaged across the three storage temperatures, almond accession Padre consistently had significantly lower pellicle luminosity and chroma values throughout the storage period as compared with the other four almond accessions (p <= 0.05). While pellicle hue angle values of Padre were significantly lower than those of Nonpareil at the start of the test (p <= 0.05), Nonpareil's pellicle hue angles were significantly lower than those of Padre at the end of the storage period (p <= 0.05). Almond accession Nonpareil had the largest percentage decrease of the five almond accessions for pellicle luminosity (36.9%) and hue angle (12.5%). Regression analysis revealed significant differences in degradation rates of pellicle luminosity and chroma at all three storage temperatures (p <= 0.05), but significant differences in pellicle hue angle degradation were only evident at the lowest storage temperature (p <= 0.05).

In EXP I, gilts received intracerebroventricular (ICV) injections of 0.9% saline (saline; n=6), or 10 mu g (n= 7), 50 mu g (n=5) or 100 mu g (n=7) NPY in saline and blood samples were collected.

In EXP I, NPY suppressed LH secretion and the 100 mu g dose stimulated GH secretion. In EXP II, NPY reversed the inhibitory effect of leptin on feed intake and suppressed LH secretion, but serum GH concentrations were unaffected. These results support the hypothesis that NPY modulates feed intake, and LH and GH secretion and may serve as a neural link between metabolic state and the reproductive and growth axis in the pig.

Focusing on two Minnesota watersheds, simulation results were combined with a constrained-optimization model to evaluate the cost-effectiveness of nitrogen-abatement policies, with explicit focus on drainage. Results indicate that drained land dominates in nitrogsen abatement, and has substantially lower abatement costs relative to nondrained land. However, policies that remove drainage were not cost-effective. Further, it was found that nutrient management, a policy strongly recommended by prior research, is relatively cost-ineffective as a means of abatement on non-drained land.

Six categories of egg-containing foods were defined based on the amount of egg contained in the food, whether eggs are pooled, and the degree of cooking practiced by consumers. We used bootstrap simulation to quantify uncertainty in risk estimates due to sampling error, and sensitivity analysis to identify key sources of variability and uncertainty in the model. Because of typical model characteristics such as nonlinearity, interaction between inputs, thresholds, and saturation points, Sobol's method, a novel sensitivity analysis approach, was used to identify key sources of variability. Based on the mean probability of illness, examples of foods from the food categories ranked from most to least risk of illness were: (1) home-made salad dressings/ice cream; (2) fried eggs/boiled eggs; (3) omelettes; and (4) baked foods/breads. For food categories that may include uncooked eggs (e.g., home-made salad dressings/ice cream), consumer handling conditions such as storage time and temperature after food preparation were the key sources of variability. In contrast, for food categories associated with undercooked eggs (e.g., fried/soft-boiled eggs), the initial level of Salmonella contamination and the log(10) reduction due to cooking were the key sources of variability. Important sources of uncertainty varied with both the risk percentile and the food category under consideration. This work adds to previous risk assessments focused on egg production and storage practices, and provides a science-based approach to inform consumer risk communications regarding safe egg handling practices.

The system integrates state-of-the-art geographic information system (GIS) as well as knowledge-based reasoning and decision modeling technologies to provide decision support for a substantial portion of the adaptive management process of ecosystem management. EMDS 3.0 is implemented as an ArcMap((R)) extension and integrates the logic engine of NetWeaver((R)) to perform landscape evaluations, and the decision modeling engine of Criterium DecisionPlus((R)) for evaluating management priorities. Key features of the system's evaluation component include abilities to (1) reason about large, abstract, multi-faceted ecosystem management problems, (2) perform useful evaluations with incomplete information, (3) evaluate the influence of missing information, and (4) determine priorities for missing information. A key feature of the planning component is the ability to determine priorities for management activities, taking into account not only ecosystem condition, but also criteria that account for the feasibility and efficacy of potential management actions. Both components include powerful and intuitive diagnostic features that facilitate communicating the explanation of modeling results to a broad audience.

D'Odorico, Paolo TI On the effect of moisture bonding forces in air-dry soils on threshold friction velocity of wind erosion SO SEDIMENTOLOGY LA English DT Article DE aeolian processes; desertification; soil moisture; wind erosion ID SEDIMENT; ENTRAINMENT; WATER; CLIMATE AB Wind erosion is a dominant geomorphological process in arid and semi-arid regions with major impacts on regional climate and desertification. The erosion process occurs when the wind speed exceeds a certain threshold value, which depends on a number of factors including surface soil moisture. The understanding and modelling of aeolian erosion requires a better understanding of the soil erodibility associated with different moisture conditions. In arid regions during the dry season, the atmospheric humidity plays an important role in determining the surface moisture content and the threshold shear velocity. By a series of wind tunnel tests and theoretical analyses, this dependence of threshold velocity on near surface air humidity is shown for three soils of different textures: sand, sandy loam, and clay loam. The results show that the threshold shear velocity decreases with increasing values of relative humidity for values of relative humidity between about 40% and 65%, while above and below this range the threshold shear velocity increases with air humidity. A theoretical framework is developed to explain these dependencies assuming an equilibrium between the surface soil moisture and the humidity of the overlying atmosphere. The conditions under which soil-atmosphere equilibrium occurs were tested experimentally in the laboratory for different soils in order to determine the effect of grain surface area and texture on the time required to reach equilibrium starting from different initial conditions.

The bed sediment of the field site and flume had median diameters of 8.3 (modes of 0.4, 22.6 mm) and 1.82 mm (modes of 0.5, 5.6 mm), respectively. The laboratory and field channels had similar values of bimodal parameters, ratios of flow depth to median bed material diameter, and ratios of shear stress to critical shear stress and were judged to be comparable in the transport of bed load sediment and the resulting bed forms. Three groupings of bed forms from the laboratory flume experiments (ripple-like bed forms, bed load sheets, low-relief bed waves) were identified using the height and period of the bed forms. For the range of flow depths and discharges investigated in the flume, bed forms became higher and longer with increasing bed shear stress. Bed forms from Goodwin Creek were similar to those from the flume with comparable ratios between bed form length, height, and flow depth. The bed forms in the flume provide a positive link between rate and size fluctuations measured in the field and the bed forms. The smaller bed forms identified were sediment starved and are not considered to be dunes, while the largest bed forms in which all of the bed material sizes were mobilized in the field and laboratory were judged to be dunes.

Even though all of the cells must endure similar physical stresses associated with the cryopreservation processes, sperm from the different species are very different in size. shape and lipid composition, all of which affect cryosurvival. Thus, when a cryopreservation protocol has been optimized for sperm of one species, it may not be ideal for sperm of other species. Bovine and caprine sperm-freezing diluents, for example, contain similar ingredients, but interactions between goat seminal plasma and egg yolk are deleterious to the sperm, a situation not observed with bovine seminal plasma and egg yolk. Therefore, a thorough understanding of the specifics of sperm freezing from a particular species will improve the cryosurvival of sperm front that species. This review updates information relating to the cryopreservation of goat semen, with emphasis on the peculiarities specific to the species. The topics discussed include the effects of goat seminal plasma during cryopreservation, sperm dilution and concentration, freezing and thawing methodologies, the components of cryopreservation diluents, and traditional and recently investigated cryoprotectants. In addition, suggestions for creating a standardized freezing protocol for goat semen are also presented. Published by Elsevier B.V.

The effects of these pesticides on fatty acid methyl ester (FAME) profiles and selected enzymatic activities were evaluated in fumigated soils and a nonfumigated control at 1, 3, 7, 14, 21, 28, and 90 days post-fumigation. Bacterial (a15:0, i15:0, i16:0, cy17:0, a17:0 and i17:0) and fungal (18:2 omega 6, 18:3 omega 6, 18:1 omega 9) FAMEs were initially (I day post-fumigation) reduced by fumigation with CP-EC, InLine, and Midas. Microbial communities of soils fumigated with MeBr+CP, MITC, and PrBr resembled those of the control soil. At 14-28 days post-fumigation, FAME profiles were changed in all fumigated soils relative to the control, with the exception of soils treated with MITC. At 90 days post-fumigation, FAME profiles suggested that actinomycetes (10 Me 16:0, 10 Me 17:0, 10 Me 18:0) and Gram-positive bacteria may recover preferentially after fumigation with most of the pesticides studied. Among the fumigants tested, InLine, Midas, and CP-EC had a higher potential to alter the microbial community structure in the longer term than MeBr + CP, PrBr and MITC, with MITC having the least effect. Soil enzyme activities in fumigated microcosms were significantly (P <= 0.037) different from the nonfurnigated soil, with the exception of beta-glucosidase in soils treated with PrBr and MITC, and dehydrogenase in MeBr+CP-fumigated soils. Over the 90-day study, soil fumigation (average of all fumigants and sampling dates) reduced the activities of arylsulfatase (62%), dehydrogenase (35%), acid phosphatase (22%), and beta-glucosidase (6%), suggesting that S mineralization in soils and the total oxidative potential of microorganisms were more affected by fumigation than P and C mineralization. This study also indicates that soil fumigation with MeBr + CP alternative biocides has the potential to alter microbial communities and important key reactions involved in nutrient transformation.

It is uncertain, however, how the activity of soil macrofauna affects atrazine fate and transport. Therefore, we investigated whether earthworms enhance atrazine biodegradation by stimulating herbicide degrading soil microflora, or if they increase atrazine persistence by facilitating herbicide sorption. Short (43 d) and medium term (86 d) effects of the earthworms Lumbricus terrestris and Aporrectodea caliginosa on mineralization, distribution, and sorption of Uring-C-14 atrazine and on soil C mineralization was quantified in packed-soil microcosms using silt loam soil. A priming effect (stimulation of soil C mineralization) caused by atrazine supply was shown that likely lowered the earthworm net effect on soil C mineralization in atrazine-treated soil microcosms. Although earthworms significantly increased soil microbial activity, they reduced atrazine mineralization to (CO2)-C-14-C from 15.2 to 11.7% at 86 d. Earthworms facilitated formation of non-extractable atrazine residues within C-rich soil microsites that they created by burrowing and ingesting soil and organic matter. Atrazine sorption was highest in their gut contents and higher in casts than in burrow linings. Also, gut contents exhibited the highest formation of bound atrazine residues (non-extractable atrazine). Earthworms also promoted a deeper and patchier distribution of atrazine in the soil. This contributed to greater leaching losses of atrazine in microcosms amended with earthworms (3%) than in earthworm-free microcosms (0.003%), although these differences were not significant due to high variability in transport from earthworm-amended microcosms. Our results indicated that earthworms, mainly by casting activity, facilitated atrazine sorption, which increased atrazine persistence. As a consequence, this effect overrode any increase in atrazine biodegradation due to stimulation of microbial activity by earthworms. It is concluded that the affect of earthworms of atrazine mineralization is time-dependent, mineralization being slightly enhanced in the short term and subsequently reduced in the medium term.

Reducing the pH of high metal soil, however, could negatively affect soil ecosystem function and health. The objectives of this study were to characterize the quantitative causal relationship between pH and soil biological activities in two Zn and Cd contaminated soils and to investigate the relationship between metals and soil biological activities under low pH. Soils were adjusted to five or six different pH levels by sulfur addition, followed by salt leaching. Thlaspi caerulescens was grown for 6 months, and both the rhizosphere and non-rhizosphere soil biological activities were tested after harvest. Reducing pH significantly lowered soil alkaline phosphatase activity, arylsulphatase activity, nitrification potential, and respiration. However, acid phosphatase activity was increased with decreasing pH. The relationship between soil biological activities and pH was well characterized by linear or quadratic regression models with R 2 values ranging from 0.57 to 0.99. In general, the three enzyme activities, nitrification potential, and the ratio of alkaline phosphatase to acid phosphatase activity were very sensitive indicators of soil pH status while soil respiration was not sensitive to pH change. The rhizosphere soil had higher biological activities than non-rhizosphere soil. The negative effects observed in the non-rhizosphere soil were alleviated by the rhizosphere influence. However, rhizosphere soil after 6 months phytoextraction showed lower nitrification potential than non-rhizosphere soil, probably due to substrate limitation in our study. (c) 2006 Elsevier Ltd.

Modifying sprinkler irrigation systems to reduce droplet energy may reduce surface sealing and crusting, thereby increasing emergence. From 1997 to 2001, we evaluated the effects of sprinkler droplet kinetic energies of 0, 8, and 16 J kg(-1) on in situ surface penetration resistance (PR, a measure of crust strength), aggregate stability (a measure of a soil's resistance to breakdown), and water-stable aggregate size distribution, expressed as a mean weight diameter (MWD). Each year near Kimberly, ID, we planted sugarbeet (Beta vulgaris L.) into an initially tilled field of structurally weak Portneuf silt loam (Durinodic Xeric Haplocalcid), then irrigated two to four times using a lateral-move sprinkler system with spray heads having either smooth or spinning, four-groove deflector plates. After the first and last irrigation each year, we measured PR in situ and collected soil samples at the surface, 0 to 6 mm. When measured after one irrigation, PR increased, and aggregate stability generally decreased as droplet energy increased, although the magnitude of the response differed from year to year. After multiple irrigations, PR decreased linearly with increasing droplet energy, likely due to erosion of the crusted surface. Five-year average MWD after multiple irrigations decreased by 10%, to 0.42 mm, with droplet energies of 8 J kg(-1) or more. Trend analysis of soils data from 1998 to 2001 revealed that droplet energies >= 10.6 J kg(-1) decreased MWD most. Producers should reduce sprinkler droplet kinetic energy to < 10.6 J kg(-1) to minimize surface structural breakdown of recently tilled soil.
