TY - JOUR T1 - Cuticular Hydrocarbons of Kapala sulcifacies (Hymenoptera: Eucharitidae) and Its Host, the Ponerine Ant Ectatomma ruidum (Hymenoptera: Formicidae) AN - 18216803; 5285178 AB - Cuticular hydrocarbons from the ponerine ant Ectatomma ruidum Roger and a highly integrated eucharitid myrmecophile, Kapala sulcifacies (Cameron), associated with it, have been characterized. Ninety hydrocarbons were identified from the ant, 55 hydrocarbons from the female wasp and 54 hydrocarbons from the male wasp. The wasps and ants share 40 hydrocarbons. These shared 40 hydrocarbons represent 92.6% of their hydrocarbon composition for female Kapala, 84.3% for male Kapala and 67.7% for the ants. The wasps have a carbon number range of C sub(27) to C sub(35); the ants have a range of C sub(23) to C sub(35). Both species possess n-alkanes, C sub(27) to C sub(33) for the wasps, C sub(23) to C sub(34) for the ants. Both species also possess major quantities of Z-7- and Z-9 alkenes: C sub(29) to C sub(33) for the wasps; C sub(23) to C sub(35) for the ants. The female wasps possess a low amount of a conjugated C sub(31) diene (neither the ants nor the male wasps possess this hydrocarbon), and the ants, but not the wasps, contain low quantities of nonconjugated dienes (carbon numbers of C sub(23) to C sub(29)) with double bonds at Delta super(9), and Delta super(14). Both wasps and ants share homologous series of 3-, 5-, 10-, 11-, 12-, 13-, 15- and 17-methyl branched alkanes. Ants and wasps also share a homologous series of 3,7-dimethyl alkanes. Other internally branched dimethyl alkanes are found in both ants and wasps, but only 11, 15-DiMeC sub(29) is shared. Wasps have 7, 15- and 10, 14-dimethyl alkanes while the ants have 15,19-dimethyl alkanes. Kapala sulcifacies and E. ruidum both possess hydrocarbons of the 5, X-, 11, X-, 12, X- and 13, X-DiMe series, but the compounds involved are not shared because they represent different compounds. Behavioral observations indicate that the ants accept the newly emerged adult parasitoids with no evidence of agonistic behavior for a period of time after adult eclosion. Nevertheless, the chemical deception is not completely efficient because young adult Kapala are soon ejected from the nest by transportation by their host. These transportations frequently occur after seizure at the base of the wasps' characteristic scutellar spines, such structures allowing for easy transportation without injury for the parasite. Moreover, if no method of escaping the colony is provided, the ants ultimately attack the parasitoids. The substantial chemical overlap of the cuticular hydrocarbon profiles of the ants and wasps are discussed in the context of the social life of the colony.

Stoneville 474 supported higher numbers of B. tabaci biotype B eggs, nymphs and adults, and also had higher numbers of stellate trichomes on abaxial leaf surfaces compared with other cotton cultivars. Siokra L-23, in general, had fewer stellate trichomes and also fewer whiteflies. However, the positive trichome-whitefly density relationships were affected by the ages of leaves from different main stem cotton nodes. The youngest leaves on main stem node 1 below the terminal for all cultivars had higher numbers of stellate trichomes but fewer whiteflies compared with older leaves.

The C. capitata #2 diet was prepared in two forms, agar and liquid and both showed comparable performance to the standard diet but the agar diet is considered to be the best diet tested. Adults reared on the agar diet produced more eggs than those on a protein hydrolysate-sugar (1:3) diet. Flies fed on diets lacking nutrient groups, such as the 10 essential amino acids, eight nonessential amino acids or the combination of cholesterol, inositol, and choline, produced fewer eggs. Those fed on the diet without the 14 vitamins, cholesterol, inositol, or choline produced a normal number of eggs. Increasing the sugar content in the diet did not affect egg production or hatch. Sugar concentration in the diet influenced fly survival.

O. Elder, J. E. Keen, G. R. Siragusa, G. A. Barkocy- Gallagher, M. Koohmaraie, and W. W. Laegreid, Proc. Natl. Acad. Sci. USA 97:2999-3003, 2000). The study implied relationships between cattle infection and carcass contamination within single-source lots as well as between preevisceration and postprocessing carcass contamination, based on prevalence. These relationships now have been verified based on identification of isolates by genomic fingerprinting. E. coli O157 isolates from all positive samples were analyzed by pulsed-field gel electrophoresis of genomic DNA after digestion with XbaI. Seventy-seven individual subtypes (fingerprint patterns) grouping into 47 types were discerned among 343 isolates. Comparison of the fingerprint patterns revealed three clusters of isolates, two of which were closely related to each other. Remarkably, isolates carrying both Shiga toxin genes and nonmotile isolates largely fell into specific clusters. Within lots analyzed, 68.2% of the postharvest (carcass) isolates matched preharvest (animal) isolates. For individual carcasses, 65.3 and 66.7% of the isolates recovered postevisceration and in the cooler, respectively, matched those recovered preevisceration. Multiple isolates were analyzed from some carcass samples and were found to include strains with different genotypes. This study suggests that most E. coli O157 carcass contamination originates from animals within the same lot and not from cross-contamination between lots. In addition, the data demonstrate that most carcass contamination occurs very early during processing.

However, in some situations, exchangeable aluminum is leached which could enter waterways and potentially cause adverse off-site impacts. Due to relatively high solubility, gypsum itself has potential to impact stream water chemistry. In this study, 8250 kg ha super(-1) gypsum was applied to plots in a steep 4.3 ha-pasture watershed in central Appalachia. Changes in the 0-40 cm soil profile and changes in water chemistry at a flume below a seep which drains the watershed were measured in response to this application. After the end of the second growing season, and a total rainfall of 1.7 m, 46% of the applied gypsum calcium was still in the top 40 cm of soil. The rainfall had a 11.4% efficiency rate of transporting gypsum out of the top 40 cm compared to movement of a saturated solution through an inert medium. Of the applied gypsum sulfate, 3.4% exited the watershed through stream flow. Maximum gypsum concentrations in stream flow, which occurred during a storm event, were 34 ppm or <1.5% of saturation levels. No detectable aluminum was measured in stream flow at the flume. These findings indicate that as long as a minor part of watersheds such as this one has gypsum applied at rates less than 10,000 kg ha super(-1), off-site environment impacts should be minimal.

AN - 71004057; 11457476 AB - Inflammation-induced changes in serum protein profiles and the effects of such serum on a chicken macrophage cell line HD11 were studied to find whether the changes in serum affect cellular immunity. Four-week-old male broiler chickens were injected subcutaneously with either olive oil or 50% croton oil mixed in olive oil to induce inflammation. The birds were bled at 48h after injection, and serum protein profiles were compared using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and densitometric evaluation. At 48h post-injection the serum from croton oil-injected birds showed distinct changes in protein profiles characterized by a selective increase or decrease in levels of several serum proteins. The protein bands which showed increases had relative molecular weights (Mr) corresponding to 65kilo Daltons (kD), 42kD, and two or more proteins with Mr> or =200kD. The levels of serum albumin (49kD), and a 56kD protein were reduced in croton oil-injected birds. The modulating effects of such serum on HD11 cells were studied using bacterial lipopolysaccharide (LPS) or phorbol myristate acetate (PMA) induced functional activation of these cells. The LPS-induced interleukin-6 (IL-6) production by HD11 cells was not affected by the presence of either olive oil-treated control or croton oil-treated inflammatory serum but nitrite production was enhanced by the inflammatory serum. Similarly, inflammatory serum also enhanced PMA-induced respiratory burst measured using dichlorofluorescein diacetate (DCF-DA) oxidation mediated by reactive oxygen intermediates. These results suggest that inflammatory serum can modulate macrophage function by influencing the production of reactive oxygen and nitrogen species which could affect their phagocytic and bactericidal activities.

These mAbs were used to develop a mAb-based antigen capture ELISA specific for chicken IL-2 detection. Anti-IL-2 mAbs bound specifically to E. coli-derived rchIL-2 in ELISA and identified a 16 kDa IL-2 polypeptide band in Western blot. Several mAbs were shown to neutralize the biological activities of both rchIL-2 and native chicken IL-2 as measured by concanavalin A (ConA)-induced lymphocyte proliferation assay, IL-2 bioassay, and natural killer cell assay. Among the neutralizing mAbs, the mAb chIL-2/11 was most potent in neutralizing IL-2 activity. To develop a sensitive ELISA for the detection of chicken IL-2, an antigen capture ELISA was developed using the mAb chIL-2 /16 as the antigen capture antibody and rabbit anti-IL-2 peptide antibody as the detection antibody. Using the mAb-based antigen capture ELISA, significant correlation between the level of IL-2 detected in bioassays and in ELISA was observed. These results showed that the mAb-based antigen capture ELISA is less time-consuming and more reliable compared to a conventional IL-2 bioassay for chicken IL-2. These neutralizing mAbs will facilitate basic immunobiological studies of the role of IL-2 in normal and disease states in chickens.

The strains were resistant to ampicillin (30), cefoxitin (22), cefotaxime (30), ceftriaxone (30), ceftazidime (30) and aztreonam (28), but susceptible to cefepime (30) and imipenem (26). Twenty-eight of 30 isolates possessed a transferable resistance confirmed by conjugation and isolation of 79-89-kb plasmids. The b-lactam resistance was due to production of b-lactamases and ceftazidime proved to be stronger b-lactamase inductor than ceftriaxone. Twenty-five clinical isolates expressed transferable extended spectrum b-lactamases, and chromosomally encoded AmpC b-lactamase.

AN - 72330653; 11760118 AB - Cysteine (Cys) and cystine residues in proteins are unstable under conditions used for acid hydrolysis of peptide bonds. To overcome this problem, we proposed the use of the S-pyridylethylation reaction to stabilize Cys residues as pyridylethyl-cysteine (PEC) protein derivatives. This suggestion was based on our observation that two synthetic derivatives formed by pyridylethylation of the SH group of Cys with either 2-vinylpyridine (2-VP) or 4-vinylpyridine (4-VP), designated as S-beta-(2-pyridylethyl)-L-cysteine (2-PEC) and S-beta-(4-pyridylethyl)-L-cysteine (4-PEC), were stable under acid conditions used to hydrolyze proteins. This was also the case for protein-bound PEC groups. Since their discovery over 30 years ago, pyridylethylation reactions have been widely modified and automated for the analysis of many structurally different proteins at levels as low as 20 picomoles, to determine the primary structures of proteins and to define the influence of SH groups and disulfide bonds on the structures and functional, enzymatic, medical, nutritional, pharmacological, and toxic properties of proteins isolated from plant, microbial, marine, animal, and human sources. Pyridylethylation has been accepted as the best method for the modification of Cys residues in proteins for subsequent analysis and sequence determination. The reaction has also been proposed to measure D-Cys, homocysteine, glutathione, tryptophan, dehydroalanine, and furanthiol food flavors. This integrated overview of the diverse literature on these reactions emphasizes general concepts.

AN - 71183583; 11561838 AB - The braconid wasp, Fopius arisanus (Sonan), a biological control agent for Mediterranean fruit fly, Ceratitis capitata (Wiedemann), was studied in coffee, Coffea arabica L. Fopius arisanus, comprised 79.3% of the total parasitoids (7,014) recovered from fruits collected at three small coffee farms. Data from seasonal host/parasitoid studies at a large coffee plantation also suggested that the most effective natural enemy of C. capitata in coffee may now reside in Hawaii. The original parasitoids introduced into Hawaii for C. capitata control (Diachasmimorpha tryoni (Cameron), Tetrastichus giffardianus Silvestri, and Dirhinus giffardii Silvestri) are now rare. Abundance of F. arisanus with respect to other parasitoids collected was influenced by elevation (274, 457, 610 m). Fopius arisanus was the dominant parasitoid at all three elevations, Diachasmimorpha longicaudata (Ashmead) occurred consistently, and T. giffardianus was abundant only at low elevation. The impacts on C. capitata and F. arisanus populations of bait sprays containing malathion, spinosad, or phloxine B applied to coffee were also evaluated. All three bait sprays suppressed C. capitata populations. Spinosad and phloxine B bait sprays appeared less harmful to the wasp than malathion. Fopius arisanus offers the potential for areawide management of C. capitata that includes biological control and integration with more environmentally safe chemical controls such as spinosad and phloxine B bait sprays.

AN - 71180632; 11561848 AB - Cucurbitacin E glycoside, extracted from a bitter mutant of Hawkesbury watermelon [Citrulls lanatus (Thunb.) Matsum. & Nakai (Syn. Citrullus vulgaris Schrad)] is the active ingredient of a feeding stimulant for the corn rootworm complex. It is the primary component of a water-soluble bait that can be combined with toxins for adult diabroticite control. Studies were conducted using phloxine B (D&C Red 28), a xanthene dye, as the toxin. This dye was efficacious against Diabrotica undecimpunctata howardi Barber, spotted cucumber beetle, and Acalymma vittatum (F.), striped cucumber beetle, in cucumber plots and could be recovered from cucumber leaves for 8 d after treatment. The average amount of dye recovered per dead spotted cucumber beetle at 8 d after treatment was 0.173 microg. Concentrated and sugar-free fermented forms of the watermelon extract were developed and compared with the fresh juice in field applications on cucumber plants. There was no significant difference in mortality of beetles from phloxine B-bait prepared with fresh, fermented, or concentrated extract, although in laboratory studies, fermented juice had higher feeding stimulant activity.

AN - 71160489; 11548529 AB - Improvements in food safety in the United States of America are currently limited by the lack of an open, reliable and uniform animal identification system. Public health would benefit from the development of such a system because this would permit accountability for an prevention of food safety hazards, including residues and harmful pathogens. In addition, the public would benefit because data collection and long-term research studies are currently hampered by the lack of animal identification. Understanding of the ecology of food-borne pathogens in the production and handling period before slaughter needs to be improved. Animal identification will permit packers and consumers to reward producers for using food safety-related production practices. Food animal producers do not regularly receive an economic advantage for voluntarily undertaking food safety-related production practices. As a result, the original source of many food animals that enter official establishments is unknown. However, the hazard analysis and critical control point system allows some producers to offer identified animals under verified production control programmes or to enter into agreements with packers with regard to the food safety status of animals.

In this method, samples extracted from chicken liver and muscle are further purified by microdialysis, separated on an LC column, and the FQs detected by their fluorescence. Recoveries from fortified chicken liver and muscle samples are at least 70% with limits of quantitation (microg/kg) for the FQs in liver (and muscle) as follows: 0.3 (0.4) for danofloxacin, 0.8 (0.2) for desethylene ciprofloxacin, 2 (1) for norfloxacin, 2 (0.8) for enrofloxacin, 3 (1) for ciprofloxacin, and 5 (2) for sarafloxacin. Enrofloxacin and ciprofloxacin are determined in enrofloxacin-incurred chicken liver and muscle samples using this method.

AN - 71103425; 11510645 AB - The preparation and distribution of fresh-cut produce is a rapidly developing industry that provides the consumer with convenient and nutritious food. However, fresh-cut fruits and vegetables may represent an increased food safety concern because of the absence or damage of peel and rind, which normally help reduce colonization of uncut produce with pathogenic bacteria. In this study, we found that Salmonella Enteritidis populations can (i) survive on fresh-cut melons and apples stored at 5 degrees C, (ii) increase up to 2 log units on fresh-cut fruits stored at 10 degrees C, and (iii) increase up to 5 log units at 20 degrees C during a storage period of 168 h. In addition, we examined the effect of lytic, Salmonella-specific phages on reducing Salmonella numbers in experimentally contaminated fresh-cut melons and apples stored at various temperatures. We found that the phage mixture reduced Salmonella populations by approximately 3.5 logs on honeydew melon slices stored at 5 and 10 degrees C and by approximately 2.5 logs on slices stored at 20 degrees C, which is greater than the maximal amount achieved using chemical sanitizers. However, the phages did not significantly reduce Salmonella populations on the apple slices at any of the three temperatures. The titer of the phage preparation remained relatively stable on melon slices, whereas on apple slices the titer decreased to nondetectable levels in 48 h at all temperatures tested. Inactivation of phages, possibly by the acidic pH of apple slices (pH 4.2 versus pH 5.8 for melon slices), may have contributed to their inability to reduce Salmonella contamination in the apple slices. Higher phage concentrations and/or the use of low-pH-tolerant phage mutants may be required to increase the efficacy of the phage treatment in reducing Salmonella contamination of fresh-cut produce with a low pH.

AN - 71030711; 11470752 AB - Chronic and excessive ethanol intake decreases hepatic retinoic acid (RA) concentrations, which may play a critical role in ethanol-induced hyperproliferation in hepatocytes. The present study was conducted to determine whether RA supplementation in chronic ethanol-fed rats could restore hepatic RA concentrations to normal levels and modulate hepatocyte hyperproliferation. Male Sprague-Dawley rats were divided into four groups: control, ethanol-fed, ethanol-fed + 50 microg all-trans-RA/kg body wt and ethanol-fed + 100 microg all-trans-RA/kg body wt. Ethanol was given to rats at 6.2% (v/v) in a liquid diet to provide 36% of total caloric intake. Control animals received the same amount of liquid diet with isocaloric maltodextrin in place of ethanol. Results show that the ethanol treatment in rats for a month significantly increased the mean number of proliferating cell nuclear antigen (PCNA)-positive hepatocytes [4.96 +/- 1.36% (ethanol-fed) versus 0.29 +/- 0.08% (control), P < 0.05]. This increase was associated with the induction of hepatic c-Jun protein (6.5-fold increase) and cyclin D1 protein (3-fold increase) in ethanol-fed animals as compared with controls. Furthermore, activator protein 1 (AP-1) DNA-binding activity was significantly higher in hepatic nuclear extracts from ethanol-fed rats than those from controls. In contrast, RA supplementation in ethanol-fed rats raised hepatic RA concentration to normal levels and almost completely abolished the ethanol-enhanced c-Jun, cyclin D and AP-1 DNA-binding activities. Moreover, RA supplementation at both doses markedly suppressed the ethanol-induced PCNA-positive hepatocytes by approximately 80%. These results demonstrate that the restoration of hepatic RA concentrations by dietary RA supplementation suppresses ethanol-induced hepatocyte proliferation via inhibiting c-Jun overexpression, and suggest that RA may play a role in preventing or reversing certain types of ethanol-induced liver injury.

To enhance the evaluation, understanding, and management of sediments in shallow water habitats, a new approach must be developed in order to provide a more holistic assessment and cartographic representation of the sediment column. Having demonstrated that shallow water sediments undergo pedogenic processes and are systematically distributed across the subaqueous landscape, we applied this new technique to the development of subaqueous soil resource inventories of Sinepuxent Bay, MD and Indian River Bay, DE. These efforts indicate that the present concept of sediment as unconsolidated geologic materials must give way to a new concept--the concept of subaqueous soils. In addition, our studies indicate the need to alter present methodologies for the acquisition and cartographic representation of sediment data through the utilization of the soil-landscape paradigm and a classification scheme (such as Soil Taxonomy) for the development of subaqueous soil resource inventories. Here we present the supporting rationale for the development of subaqueous soil resource inventories; and through a synthesis of geologic and pedologic principles and concepts, propose a new state factor equation to explain subaqueous soil genesis and distribution.

Social scientists, physical scientists, and politicians have roles in developing indicators that reflect the demands of diverse interest groups. We review the US Department of Agriculture's Conservation Reserve Program (CRP), the largest agricultural conservation program of the United States, to determine how a set of environmental indicators were developed and used, and assess results of their application. The use of such indicators has helped the CRP increase and broaden the program's environmental benefits beyond erosion reduction, which was the primary focus of early program efforts, to meet other demands. This case study provides an example about how integration and assessment for the purpose of managing public resources requires more than natural science disciplines. Social science can help explain how public values influence what information is collected and how it is interpreted. Examples are given to show how the indices used for the CRP integrated science, politics and social values. In the end, the environmental benefits index (EBI) used to target US$ 20 billion of CRP funds reflects compromises made between science and policy considerations. It is our intention that studying this index will yield ideas and understanding from the natural science community that develops ecosystem indices about how to better plug in to programs in the future.

Material that normally would not be expected to erode when exposed to flowing water can fail along existing fracture planes. Conventional strength testing does not necessarily account for these potential failure surfaces. The objective of this study was to investigate the dominant parameters that cause failure of a fractured block matrix. A study was conducted by placing a matrix of blocks downstream of an overfall. The discharge over the overfall was increased until the block matrix failed due to the forces transmitted by the impinging flow. The block size, block orientation, and overfall height were varied systematically over a range of flow rates. Test results are presented, and the dominant failure mechanisms are described. The failure discharge was observed to decrease as the overfall height increased. This result was expected because the larger drops allow the flow to impact the surface with more energy. The failure discharge was also observed to increase if the block was placed with its long axis oriented vertically. This orientation distributed the block weight over a smaller area, thus requiring an increased pressure to dislodge the block. The repeatability of these fractured material tests was also examined, as was the block layer thickness. In addition to the hydraulic erosion of fractured materials, preliminary results on the measurement of pressures below a block matrix are discussed. This article provides fundamental research information concerning scour hole development and headcut erosion in fractured materials.

To provide insight into these processes, model assessments should be performed under a variety of conditions. We evaluated the macropore component of the RZWQM using undisturbed soil blocks with natural macropores. To accomplish this, atrazine, alachlor, and bromide were surface-applied to nine 30 x 30 x 30 cm blocks of undisturbed, no-till silt loam soil at three water contents (dry, intermediate, and wet). One hour later, we subjected the blocks to a 0.5-h, 30-mm simulated rain. Percolate was collected and analyzed from 64 uniform size cells at the base of the blocks. After percolation ceased, the soil was sectioned and analyzed to determine chemical distribution. We tested the chemical sub-component of macropore flow using these blocks following hydrologic calibration, while a separate set of blocks was used to calibrate selected chemical parameters. Parameterization of the macropore component included measuring the effective macroporosity (50% of percolate producing macropores) and calibrating the effective soil radius (0.6 cm). The effective soil radius represents the soil surrounding the macropores that interacts with macropore flow. This parameterization strategy resulted in accurate simulations of the composite chemical concentrations in percolate (i.e., all simulated chemical concentrations were within a factor of 2.0 of the average observed value). However, observed herbicide concentration in percolate decreased with cumulative percolate volume, while simulated concentrations increased. Model modifications, such as incorporating a dynamic effective macroporosity (effective macroporosity increase with increasing rainfall) and chemical kinetics in macropores, may improve simulations.

All samples were collected at production facilities and not at retail. We report results here for the years 1990 through 1999. Prevalence data for Salmonella, Listeria monocytogenes, Escherichia coli O157:H7, or staphylococcal enterotoxins in nine different categories of RTE meat and poultry products are presented and discussed. The prevalence data have certain limitations that restrict statistical inferences, because these RTE product-testing programs are strictly regulatory in nature and not statistically designed. The cumulative 10-year Salmonella prevalences were as follows: jerky, 0.31%; cooked, uncured poultry products, 0.10%; large-diameter cooked sausages, 0.07%; small-diameter cooked sausages, 0.20%; cooked beef, roast beef, and cooked corned beef, 0.22%; salads, spreads, and pates, 0.05%; and sliced ham and luncheon meat, 0.22%. The cumulative 3-year Salmonella prevalence for dry and semidry fermented sausages was 1.43%. The cumulative 10-year L. monocytogenes prevalences were as follows: jerky, 0.52%; cooked, uncured poultry products, 2.12%; large-diameter cooked sausages, 1.31%; small-diameter cooked sausages, 3.56%; cooked beef, roast beef, and cooked corned beef, 3.09%; salads, spreads, and pates, 3.03%; and sliced ham and luncheon meat, 5.16%. The cumulative 3-year L. monocytogenes prevalence for dry and semidry fermented sausages was 3.25%. None of the RTE products tested for E. coli O157:H7 or staphylococcal enterotoxins was positive. Although FSIS and the industry have made progress in reducing pathogens in these products, additional efforts are ongoing to continually improve the safety of all RTE meat and poultry products manufactured in federally inspected establishments in the United States.

Aerobic plate count (APC) for each produce or seed type as determined on Pseudomonas agar F (PAF) with incubation at 28 degree C was in the range of 4 to 7 log CFU per g of tissue or seed. There was no significant difference (P greater than or equal to 0.05) in APC when the determinations were made with three agar media including PAF, brain heart infusion agar, and plate count agar. However, the APC as determined from plates that were incubated at 28 degree C was significantly (P less than or equal to 0.05) higher than with incubation at 37 degree C. Fluorescent pseudomonads accounted for 23 to 73% of APC and 6 to 18% of APC recovered from carrots, pepper, and lettuce were pectolytic. Forty-eight strains of pectolytic bacteria were randomly isolated and identified, respectively, as members of the genera of Pseudomonas, Erwinia, Bacillus, Xanthomonas, or Flavobacterium. Lactic acid bacteria and/or yeast were consistently isolated from baby carrots, lettuce, and sprouting seeds (alfalfa or clover) but not from green bell peppers. Approximately 120 strains of indigenous microflora were tested for their ability to inhibit the growth of Salmonella Chester, Listeria monocytogenes, Escherichia coli, or Erwinia carotovora subsp. carotovora on PAF. Six isolates capable of inhibiting the growth of at least one pathogen were isolated and identified, respectively, as Bacillus spp. (three strains), Pseudomonas aeruginosa (one strain), Pseudomonas fluorescens (strain A3), and yeast (strain D1). When green pepper disks were inoculated with strains A3 and D1, the growth of Salmonella Chester and L. monocytogenes on the disks was reduced by 1 and 2 logs, respectively, over a period of 3 days. Application of strains A3 and D1 as potential biopreservatives for enhancing the quality and safety of fresh produce is discussed.

Stationary-phase cells were inoculated into sterile media to give initial populations of 6 to 7 log sub(10) CFU/ml. Bacterial populations were determined periodically by aerobic plate counts. Survivor curves were fitted from plate count data using a two-phase linear model to derive lag times and slopes of the curves, from which D-values and times to a 4-D (99.99%) inactivation (T sub(4D)) were calculated. In general, survival increased as temperature decreased and as pH increased. Bacterial populations reached undetectable levels (<1.3 log sub(10) CFU/ml) at 37, 28, 19, 12, and 4 degree C in media adjusted to pH 4 after 5, 15, 23, 85, and 85 days, respectively, and in media adjusted to pH 3 after 1, 7, 9, 16, and 29 days, respectively. In media adjusted to pH 2, bacterial populations were stable for 2 to 12 h at temperatures of 19 degree C or lower and reached undetectable levels after 1 to 3 days, while at 28 and 37 degree C, the bacteria were undetectable after 8 and 2 h, respectively. In media adjusted to pH 5, bacterial levels decreased only 0.5 to 1.5 log sub(10) CFU/ml after 75 days at 4 degree C and decreased to undetectable levels after 135 days at 12 degree C, while growth occurred at higher temperatures. These results indicate that S. flexneri is acid resistant and that acidic foods may serve as vehicles for infection.

Crop evapotranspiration (ET) was measured using two CO sub(2) concentrations (control, c. 370 mu mol mol super(-1); FACE, ambient +200 mu mol mol super(-1)) and two irrigation treatments (well watered and water-limited). Volumetric soil water content was measured before and after each irrigation using neutron scattering techniques. Averaged over both years, elevated CO sub(2) reduced cumulative ET by 10% when plants were given ample water and by 4% under severe drought stress. Water-use efficiency based on grain yield (WUE-G) increased, due to CO sub(2) enrichment, by 9% and 19% in wet and dry plots, respectively; based on total biomass, water-use efficiency (WUE-B) increased by 16% and 17% in wet and dry plots, respectively. These data suggest that in the future high-CO sub(2) environment, water requirements for irrigated sorghum will be lower than at present, while dry-land productivity will increase, provided global warming is minimal.

Ten, 25, 60, or 100 seeds contaminated by immersion for 15 min in a suspension of E. coli O157:H7 at concentrations of 10 super(6) or 10 super(8) cfu/ml were mixed with 20 g of non-inoculated seeds in plastic trays for sprouting. The seeds were sprayed with tap water for 15 s every hour and spent irrigation water was collected at intervals and tested. E. coli O157:H7 was detected in non-enriched water by both the TaqMan registered PCR (30 of 30 samples) and the immunoassay (9 of 24 samples) in water collected 30 h from the start of the sprouting process. However, enrichment of the spent irrigation water in brain heart infusion (BHI) broth at 37 degree C for 20 h permitted detection of E. coli O157:H7 in water collected 8 h from the start of sprouting using both methods, even in trays containing as few as 10 inoculated seeds. The TaqMan registered PCR assay was more sensitive (more positive samples were observed earlier in the sprouting process) than the immunoassay; however, the immunoassay was easier to perform and was more rapid. At 72 h after the start of the sprouting process, the sprouts were heated at 100 degree C for 30 s to determine the effectiveness of blanching for inactivation of E. coli O157:H7. All of the 32 samples tested with the TaqMan registered assay and 16 of 32 samples tested with the Quix super(TM) assay gave positive results for E. coli O157:H7 after enrichment of the blanched sprouts at 37 degree C for 24 h. In addition, the organism was detected on Rainbow registered Agar O157 in 9 of 32 samples after 24 h of enrichment of the blanched sprouts. In conclusion, E. coli O157:H7 was detected in spent irrigation water collected from sprouts grown from artificially contaminated seeds by both the TaqMan registered and Quix super(TM) assays. The data also revealed that blanching may not be effective to completely inactivate all the E. coli O157:H7 that may be present in sprouts.

These viruses are spread by the fecal-oral route and are a major cause of morbidity and mortality worldwide. Foods may be contaminated at any time pre- or post-harvest; however, many outbreaks are associated with foods handled by infected restaurant workers. Produce may be contaminated by improper irrigation or fertilization practices, by the hands of infected pickers or processors, or as the result of adulteration during any stage of handling. Outbreaks have been commonly associated with foods which are served raw or only lightly cooked, such as molluscan shellfish, fruits and vegetables, and salads or products contaminated after cooking like frosted bakery products. The farming, shellfish, processing, transportation, and restaurant industries must maintain vigilance to reduce outbreaks of enteric virus illness. Intervention strategies to enhance product safety include increased industry and consumer education; changes in industrial practices, product management, and processing technologies; worker immunizations; and the development of improved monitoring tools for the detection of enteric viruses in foods.

The activity of alpha -chymotrypsin was studied to determine whether trends in solvent polarity, water activity, and enzyme support properties, observed with this enzyme in conventional organic solvents, hold for the novel environment provided by ionic liquids. alpha -Chymotrypsin freeze-dried with K sub(2)HPO sub(4), KCl, or poly(ethylene glycol) demonstrated no activity in [bmim][PF sub(6)] or [omim][PF sub(6)] at very low water concentrations, but moderate transesterification rates were observed with the ionic liquids containing 0.25% water (v/v) and higher. However, the physical complexation of the enzyme with poly(ethylene glycol) or KCl did not substantially stimulate activity in the ionic liquids, unlike that observed in hexane or isooctane. Activities were considerably higher in [omim][PF sub(6)] than [bmim][PF sub(6)]. Added water was not necessary for enzyme activity when ionic liquids were combined with SC-CO sub(2). These results indicate that [bmim] [PF sub(6)] and [omim][PF sub(6)] provide a relatively polar environment, which can be modified with nonpolar SC-CO sub(2) to optimize enzyme activity.

AN - 18291752; 5340792 AB - Adaptive management (AM) is the process of implementing land management activities in incremental steps and evaluating whether desired outcomes are being achieved at each step. If conditions deviate substantially from predictions, management activities are adjusted to achieve the desired outcomes. Thus, AM is a kind of monitoring, an activity that land management agencies have done poorly for the most part, at least with respect to ground-based monitoring. Will they do better in the future? We doubt it unless costs, personnel, and future commitment are seriously addressed. Because ecosystem responses to management impacts can ripple into the distant future, monitoring programs that address only the near future (e.g., 10-20 years), are probably unreliable for making statements about resource conditions in the distant future. We give examples of this. Feedback loops between ecosystem response and adjustment of management actions are often broken, and therefore AM again fails. Successful ground-based monitoring must address these and other points that agencies commonly ignore. As part of the solution, publics distrustful of agency activities should be included in any monitoring program.

Merr.] growth and yield. Our objective was to identify quantitative trait loci (QTL) associated with the tolerance of soybean to soil waterlogging. We subjected 208 lines of two recombinant inbred (RI) populations, `Archer' x `Minsoy' and `Archer' x `Noir I', to 2 wk of waterlogging when the plants were at the early flowering stage. The control plants were not flooded. The experiment was conducted in three environments: Columbus, OH, in 1997 and 1998 and Wooster, OH, in 1998. We identified a single QTL, linked to marker Sat-064, from the Archer parent which was associated with improved plant growth (from 11-18%) and grain yields (from 47-180%) in waterlogged environments. This highly significant QTL (P = 0.02-0.000001) was identified in both RI populations and at both Columbus 1997 and 1998 environments, but not at the Wooster 1998 environment. The differences in soil type and flooding treatment (stagnant versus moving water) could have contributed to the lack of QTL identification at the Wooster 1998 environment. The Sat-064 QTL was uniquely associated with waterlogging tolerance and was not associated with maturity, normal plant height or grain yields. The Sat-064 marker maps close to the Rps4 gene for Phytophthora (Phytophthora sojae M.J. Kaufmann & J.W. Gerdemann) resistance; however, since Archer does not contain the Rps4 resistance allele, it is probably not a disease tolerance QTL. Near isogenic lines with and without the Sat-064 marker have been developed and are being field tested under waterlogging conditions to confirm the association of the QTL with the tolerance of soybean to waterlogging stress.

This near-surface soil moisture product (W) at 800 m pixel resolution together with land use and fractional vegetation cover (f sub(c)) estimated from normalized difference vegetation index (NDVI) was used for computing spatially distributed sensible (H) and latent (LE) heat fluxes over the SGP97 domain (an area similar to 40 x 260 km) using a remote sensing model (called the two-source energy Balance-soil moisture, TSEB sub(SM), model). With regional maps of W and the heat fluxes, spatial correlations were computed to evaluate the influence of W on H and LE. For the whole SGP97 domain and full range in f sub(c), correlations (R) between W and LE varied from 0.4 to 0.6 (R similar to 0.5 on average), while correlations between W and H varied from -0.3 to -0.7 (R similar to -0.6 on average). The W-LE and W-H correlations were dramatically higher when variability due to f sub(c) was considered by using NDVI as a surrogate for f sub(c) and computing R between heat fluxes and corresponding W values under similar fractional vegetation cover conditions. The results showed a steady decline in correlation with increasing NDVI or f sub(c). Typically, parallel R parallel greater than or approximate to 0.9 for data sorted by NDVI having values less than or approximate to 0.5 or f sub(c) less than or approximate to 0.5, while parallel R parallel less than or approximate to 0.5 for the data sorted under high canopy cover where NDVI greater than or approximate to 0.6 or f sub(c) greater than or approximate to 0.7. The correlations also varied with environmental/moisture conditions, but even more significantly depending on the area selected within the SGP97 domain. Output of the spatially distributed heat fluxes over the SGP97 domain for one day were compared to the atmosphere-land exchange inversion (ALEXI) model, which uses the 5-km resolution geostationary operational environmental satellite (GOES) surface temperature data (T sub(surf)) and 10-km scale atmospheric forcing. The spatial variability in heat fluxes predicted by TSEB sub(SM) was significantly greater than ALEXI, but the domain average H and LE differed by less than 5% and 15%, respectively. High resolution ( similar to 10 m pixel) remotely sensed T sub(surf) from an airborne sensor collected over one of the main study sites were aggregated to 800-m resolution and compared to the TSEB sub(SM) simulated values as a function of remotely sensed f sub(c). There was good agreement between the model-derived and remotely sensed T sub(surf) with both indicating a linear relationship with f sub(c). The ability of the TSEB sub(SM) model to simulate T sub(surf) values in reasonable agreement with remotely sensed observations suggests the model is capable of properly partitioning the convective-energy and radiative balance of the surface between soil and vegetation components. The spatial correlation results have implications regarding the influence of near-surface soil moisture on atmospheric dynamics and the scale at which these relationships are considered.

Cross calibration of the SSM/I data to the same TMI channels showed nearly identical brightness temperatures. 19 GHz SSM/I data and soil moisture relationships were similar to those observed in previous experiments in this region. Comparison studies of the SSM/I and TMI channels revealed that only sampling areas with adequate spatial domains should be used for soil moisture validation. Analyses of the TMI 10 GHz data provide new information on potential improvements that this channel can provide for soil moisture estimation. Soil moisture maps of the region were derived for dates of coverage.

The composition of animal taxa is predicted to shift in parallel with that of dominant plants and species diversity is predicted to be greater in transitional zones than in adjacent areas. We asked whether ant species diversity and composition supported these predictions across a biome transition between shortgrass steppe and Chihuahuan desert vegetation. Neither species richness nor diversity was highest at the biome transition region as a whole, or within habitats in the biome transition. The biome transition region was not intermediate in ant species composition or in the representation of different faunal complexes. The community similarity between matched habitats shared between the biome transition zone and adjacent regions was less than that between distinct habitats occurring within regions. A zoogeographic transition for ants may occur to the north of the phytogeographic transition and may be coincident with the northern limits of monsoonal precipitation patterns. In contrast, the phytogeographic transition may be related to less extreme climatic variation within the monsoonal region occurring further south.

A portable acoustic system was developed and tested for its potential to rate the likelihood that trees in citrus groves were infested with Diaprepes abbreviatus (L.) larvae. The likelihood was rated independently by a computer program and an experienced listener that distinguished insect sounds from background noises, Diaprepes abbreviatus, Phyllophaga spp., or other pest insects were excavated from all 11 sites rated at high likelihood of infestation but were absent from 20 of 25 low-rated sites. There was a significant regression between the activity rate and the number of pest organisms present at recording sites although the correlation was weaker than between activity rate and likelihood of infestation. Although the system is at an early stage of development, the success of these field tests suggests that it has considerable potential as a tool to detect and monitor hidden infestations of insects in soil.

In southeastern Alaska in 1996-1997, the riparian forests bordering salmon streams supported, on average, higher densities, but not diversity, of forest passerines compared to non-salmon streams. The presence of salmon in the fall increases the abundance of terrestrial and aquatic invertebrates and possibly enhances food resources to riparian birds in the spring.

No prior study, however, has demonstrated the relative importance of crown-burned forests to this woodpecker species by examining its reproductive success in different forest types. We studied breeding Lewis's Woodpeckers in cottonwood (Populus fremontii) riparian forest patches of Colorado and crown-burned ponderosa pine (Pinus ponderosa) forests of Idaho to compare their reproductive success, productivity, and potential source-sink status in the two forest types. Daily nest survival rates were significantly lower in cottonwood compared to burned pine forests. Nesting success was 46% (n = 65) in cottonwood forests and 78% (n = 283) in burned pine forests. Proportion of nests destroyed by predators was significantly higher in cottonwood forests (34%) compared to burned pine forests (16%). We consistently found crown-burned forests to be potential source habitat, whereas cottonwood riparian sites were more often concluded to be potential sink habitat. Cottonwood riparian forests were surrounded primarily by an agricultural landscape where the composition and abundance of nest predators was likely very different than the predator assemblage occupying a large-scale burn in a relatively natural landscape. Conversion of riparian and adjacent grassland landscapes to agriculture and prevention of wildfire in ponderosa pine forests have likely reduced nesting habitat for this species. Prescribed understory fire is the prevailing management tool for restoring ponderosa pine ecosystems. Conditions created by crown fire may be equally important in maintaining ponderosa pine systems and conserving nesting habitat for the Lewis's Woodpecker.

Deserting vireo pairs fledged more host young within a season than pairs that accepted cowbird eggs when only successful nests were considered; parasitized acceptor nests never fledged any vireo young. Vireo pairs that deserted did not always desert parasitized nests. We observed five encounters between female cowbirds and Bell's Vireos at four nests. In one observation the female vireo used nest-protection behavior, which resulted in the cowbird egg appearing beneath the nest; this nest was not deserted. We found a total of eight nests where cowbird eggs remained on the ground below nests, five of which were abandoned. Nest desertion appears to benefit Bell's Vireos by allowing for unparasitized renests, but the stimuli eliciting nest desertion by Bell's Vireos remain in need of further study.

Pectinase activities were adsorbed onto a Poros HS (a strong cation exchanger) column in 20 M HEPES buffer at pH 7.5. The fruit-specific PME was eluted from the column with 80 mM NaCl, followed by a step to 300 mM NaCl to elute PG activity. Rechromatography of the PME activity peak with a linear gradient further resolved two PME isoenzymes and removed residual traces of PG activity. The PG activity peak was further treated with lectin affinity chromatography to provide purified PG enzyme, which was separated from a salt-dependent PME (tentatively identified as a "ubiquitous-type" isoform), and a pectin acetylesterase. The later enzyme has not been reported previously in tomato. This method provides monocomponent enzymes that will be useful for studying enzyme mechanisms and for modifying pectin structure and functional properties.

The species is threatened by the exotic hemlock woolly adelgid (HWA), Adelges tsugae; infestation by this forest pest can result in high levels of mortality of overstory trees with a resultant change in understory vegetation composition and structure. Pre-salvage harvesting of overstory hemlock results in a residual stand compositionally and structurally similar to that resulting from mortality due to adelgid infestation, except for the occurrence of standing or fallen dead trees in adelgid infested stands. The vertebrate fauna of hemlock-dominated forests is poorly studied and the effects of the mortality or removal of overstory hemlock on forest fauna in these stands is unknown. This study reports the findings of a 3-year study of the effects of pre- or green-tree salvage of overstory hemlock from hemlock-hardwood stands on terrestrial salamanders. The residual hemlock stocking was reduced an average of 60% following harvesting and the understory vegetation responded vigorously. The relative abundance of eastern redback salamanders was reduced in harvested stands but the effect was ephemeral and salamander numbers appear to be increasing within a few years of the logging. It appears that hemlock defoliation and mortality due to HWA infestation or pre-salvage harvesting of live hemlock will result in only a brief reduction in the principal terrestrial salamander of hemlock-dominated forests.

Treatments were assigned randomly to eight 12 x 8 m plots within each of two blocks. Following fires in June 1995, unfenced plots were exposed to livestock grazing over 4 years. Plots were established that either included or excluded P. glandulosa. Perennial grass cover, primarily Bouteloua eriopoda , decreased by 13% in burned plots but increased 5% in unburned areas. Conversely, perennial forb cover was 4% greater after fire. Perennial grass frequency decreased 30% more and perennial forb frequency increased 10% more following burning. Further, increases in evenness after fire resulted in a 225% increase in species diversity. Grazing also resulted in a decrease in perennial grass cover while frequency decreased 22% more in grazed than ungrazed plots. Only frequency and not cover of perennial forbs and annual grasses increased more following grazing. Presence of P. glandulosa had no differential effect on responses of non-shrub species. Fires were conducted during near drought conditions while grazing occurred during years of precipitation equivalent to the long-term average. Precipitation immediately following fire may be critical for recovery of B. eriopoda -dominated desert grasslands; relationships between fire and post-fire precipitation patterns require future investigation.

This 2.6-kb BamHI fragment corresponds to the DNA site where transposon Tn 4560 had inserted to create a nikkomycin-nonproducing mutant. A possible ORF of 660 nucleotides was found in this 2.6-kb BamHI fragment, in which the third base of each codon was either G or C in 92% of the codons. The deduced amino acid sequence coded by this ORF (TarA, tendae autoregulator receptor) shows strong homology with several gamma -butyrolactone-binding proteins that negatively regulate antibiotic production in other streptomycetes and have a helix-turn-helix DNA-binding motif. A portion (179 nucleotides) of tarA that encodes the helix-turn-helix motif was replaced with ermE, and wild-type S. tendae was transformed with this construct borne in pDH5, a gene-disruption vector. Southern hybridization indicated that ermE had inserted in the 2.6-kb BamHI region in one isolate that is erythromycin resistant. Northern hybridization indicated that tarA disruption significantly increased the amount of disrupted- tarA mRNA. This suggests that TarA negatively regulates its own synthesis. Nikkomycin production by the tarA disruptant was delayed but reached the wild-type level after longer incubation in production medium.

The two hypotheses associate plant physiological conditions to insect feeding mode and performance. We exposed tomato, Lycopersicon esculentum, to different types of growing conditions: optimal (vigorous plants), resource based stress (water and/or nutrient deficit), and physical stress (punched hole in terminal leaflets). Plant performance, foliar nutritional value for insects and chemical defenses were analyzed after 14 d. These plants were offered to insects belonging to distinct feeding guilds: the silverleaf whitefly, Bemisia argentifolii, a phloem feeder; the leafminer, Liriomyza trifolii; and the corn earworm, Heliothis zea, a leaf chewing caterpillar. The experimental conditions generated a gradient of plant growth in the following order: optimal (vigorous) > control = hole punched > no fertilizer > no water > no water and no fertilizer. The last two treatments resulted in plants with poor nutritional value (based on %water, C/N, %N) and higher levels of defensive compounds (i.e., peroxidase and total phenolics) compared with control and the vigorous plants, Hole-punching neither affected plant growth nor any of the phytochemicals measured. In a choice experiment adult whitefly ovipositioning was not affected by either vigor or punching but was reduced on the other plants (P < 0.01). Leafminer feeding and oviposition and corn earworm larval growth rates were higher on the vigorous plants and lower on the punched, no fertilizer, no water, and no water and no fertilizer host plants (P < 0.01). Regardless of insect species or bioassay method, the results in the tomato system support the plant vigor hypothesis that predicts positive association between insect performance and plant growth. The results contradict the plant stress hypothesis that rank stressed plants as better hosts for insects. The mechanisms involved are a combination of poor nutritional value and chemical defenses. We demonstrate a negative association between plant growth and chemical defense. However, induced response triggered by hole-punching was not cost effective to the plants.

(spotted cutworm) are attracted to the combination of acetic acid and 3-methyl-1-butanol (isoamyl alcohol). A controlled-release system for use of this attractant in traps was comprised of separate polypropylene vials for each chemical, with the chemical release rate delimited by a hole in the vial lid. When hole sizes for both acetic acid and 3-methyl-1-butanol were varied together, numbers of all three moth species trapped were greatest with vial hole diameters 1.0-3.0 mm. For all three species, captures of moths also were positively correlated with the ratio of acetic acid to 3-methyl-1-butanol vial bole sizes (acetic acid vial bole size was varied, 3-methyl-1-butanol vial hole size was held constant). Captures of these moths were not correlated with the ratio of 3-methyl-1-butanol/acetic acid vial hole sizes (3-methyl-1-butanol vial hole size varied, acetic acid vial hole size was held constant), over the range of hole sizes tested. Captures of L. subjuncta, M. configurata, and X. c-nigrum in a wet trap were significantly increased by the addition of boric acid to the trap drowning solution (to retard microbial growth and decomposition of specimens). In a comparison of different designs of traps baited with acetic acid and 3-methyl-1-butanol, greatest numbers of all three species were captured in a dry "bucket" trap which moths entered from near the trap top.

Previously, these strains were shown to suppress potato scab disease, caused by Streptomyces scabies, in field experiments and to inhibit in vitro growth of a wide range of plant-pathogenic fungi and bacteria. Inoculation with Streptomyces at planting significantly reduced RLN population densities in roots of both susceptible and resistant alfalfa varieties grown in either heat-treated or untreated soil. Reductions in RLN population densities were observed 6 weeks after nematode inoculation. Shoot dry matter was not affected by any treatment; root dry weight was reduced in Streptomyces plus nematode treatments compared to the nematode inoculation alone in some experiments but was not affected by Streptomyces when RLN was absent. Mutant strains not producing antibiotics in vitro also reduced RLN population densities in alfalfa roots and all strains maintained high population densities after inoculation into heat-treated soil and on alfalfa roots. These strains may be useful in multi-crop, multi-pathogen management programs to augment genetic resistance to plant diseases.

Problems fall into two general categories: 70 percent of the sampled projects had design problems, and 50 percent of the sampled projects had procedural problems. Monitoring projects implemented by land-management agencies tended to have a higher proportion of procedural problems than did university-based programs (generally graduate student research), while the frequency of design problems was similar between agencies and universities. The most common problems were poorly trained or unmotivated field crews (37 percent of projects, a procedural problem), a sampling plan that was not capable of measuring what was needed to meet project objectives (30 percent, design), delays in analyzing data (27 percent, procedure), inadequate monitoring durations (27 percent, design), and absence of the collateral information needed to interpret results (20 percent, procedure). Most of the problems could have been avoided by submission of the study design to thorough technical and statistical review, active participation of the principal investigators in field data collection, and analysis of at least some of the data as soon as information was collected so that problems could be recognized early enough to be corrected.

The pelicans were monitored to determine their daily activity budgets while using different habitats such as catfish ponds, crawfish ponds, rivers, lakes, and bayous. Pelicans foraging at catfish ponds spent about 4% of their day foraging and 96% loafing, while pelicans foraging in other habitats spent about 28% of their day foraging and 72% loafing. For an individual bird, the mean number of foraging sessions per day was 2.5 ( plus or minus 0.53 SE) and the mean length of each foraging session was 66.7 min. ( plus or minus 8.08 SE). Aerial censuses were also conducted to determine the numbers of pelicans in the delta region of Mississippi. Each year the numbers of pelicans wintering in the delta region of Mississippi peaked in February and March, corresponding with spring migration. Pelican numbers reached approximately 4,600 during February and March 1996. Pelicans were observed foraging in larger flocks for shorter periods of time on catfish ponds than in other habitats.

In an effort to better understand the discrepancy that has been consistently found between actual and hypothetical donations, we investigate an approach to estimating actual willingness to donate using contingent donations with a follow-up question in which respondents rate the level of certainty about their response to the contingent donation question. The approach allows us to estimate the magnitude of the hypothetical bias and identify the respondents responsible for the bias. Identification of the respondents responsible for the hypothetical bias is the first step toward developing an understanding of the causes and possible remedies. In this study we find that most of the respondents (80%) to the contingent donation question provide a response consistent with how we predict they would respond in an actual donation situation.

Compared to terrestrial plants, filamentous algae have exceedingly high growth and nutrient uptake rates. Moreover, they are capable of year-round growth in temperate climates, can be harvested on adapted farm-scale equipment, and yield a biomass that should be valuable as an animal feed supplement. The objective of this research was to evaluate algal turf scrubber (ATS) technology to remove nitrogen, phosphorus and chemical oxygen demand from raw and anaerobically digested dairy manure. Laboratory-scale ATS units were operated by continuously recycling wastewater and adding manure effluents daily. ATS units were seeded with algal consortia from a nearby stream and grown using dairy manures from two different dairy farms. Algal biomass was harvested weekly and dried prior to analysis for total Kjeldahl nitrogen, total phosphorus, and inorganic constituents. Wastewater samples were analyzed for total Kjeldahl nitrogen, ammonium, nitrate, orthophosphate, conductivity and chemical oxygen demand. Using a typical manure input containing 0.6-0.96 g total nitrogen day super(-1), the dried algal yield was approximately 5 g m super(-2) day super(-1). The dried algae contained approximately 1.5-2% phosphorus and 5-7% nitrogen. Algal nitrogen and phosphorus accounted for 42-100% of input ammonium-nitrogen (33-42% of total nitrogen) and 58-100% of input total phosphorus, respectively.

Productivity was defined as the volume of wood expected per hectare at age 20 and was calculated as the product of predicted individual tree volumes, an initial stocking (1600 trees ha super(-1)), and predicted survival. Impact was considered according to the transient effects of a changing climate governed by (1) physiological plasticity in the contemporary generation and (2) long-term evolutionary adjustments that provide adaptedness and optimize productivity in future generations. Direct short-term plastic responses were geographically complex and had repercussions throughout the species' distribution even when temperature fluctuations were small ( plus or minus 1 degree C) and changes in distribution were inconsequential. Evolutionary adjustments ameliorated negative short-term impacts while enhancing the positive. Scenarios that encompassed predictions for global warming produced short-term impacts that were negative in the south and positive in the north, but subsequent evolutionary adjustments projected substantial increases in productivity. The long-term adjustments may require only 1 to 3 generations in the north but 6 to 12 generations in the south, thereby taking between 200 and 1200 years.

This paper reports research conducted to document the ability of a previously developed near infrared (NIR) reflectance sensor to predict soil organic matter and soil moisture contents of surface and subsurface soils. Three soil cores (5.56 cm dia. x 1.5 m long) were collected at each of 16 sites across a 144 000 km super(2) area of the US Cornbelt. Cores were subsampled at eight depth increments, and wetted to six soil moisture levels ranging from air-dry to saturated. Spectral reflectance data (1603-2598 nm) were obtained in the laboratory on undisturbed soil samples. Data were collected on a 6.6 nm spacing with each reflectance value having a 45 nm bandpass. The data were normalized, transformed to optical density [OD, defined as log sub(10) (1/normalized reflectance)], and analyzed using stepwise multiple linear regression. Standard errors of prediction for organic matter and soil moisture were 0.62 and 5.31%, respectively. NIR soil moisture prediction can be more easily commercialized than can soil organic matter prediction, since a reduced number of wavelength bands are required (four versus nine, respectively).

Because soil degradation has both on-site and off-site effects, public policies have often tried to increase rates of conservation over privately optimal rates. Where private incentives leave off and public incentives start up is somewhat controversial, however. Physical evidence, while necessary, is not sufficient to predict conservation actions by farmers in response to the threat of degradation. This paper provides a partial explanation for why farmers may adopt differing conservation strategies, even though they share similar preferences. A model is constructed that divides soil degradation into reversible and irreversible components. We portray nutrient depletion as a reversible facet of soil degradation and soil profile depth depletion as an irreversible facet of soil degradation. Predictions of optimal management response to soil degradation are accomplished using a closed-loop model of fertilizer applications and residue management to control future stocks of soil nutrients and soil profile depth. Our model is applied to degradation data from nine soils in the north central United States. Three principal findings result: First, due to differences in initial soil properties, susceptibility to degradation, sensitivity of yield to soil depth, and yield response to alternative management practices, dynamically optimal economic strategies cannot be inferred directly from physical results but are inferred from the associated economic implications. Second, optimal residue management is more variable with respect to soil type than to the erosion phase of the soil, implying that substantial gains to targeting are possible. Third, nutrient depletion is a more compelling motivator for adopting residue management than soil profile depth depletion. This implies that motivating residue management requires programs that pay even greater attention to reversible degradation, and therefore the overall farm management implications, rather than strictly to protect topsoil from irreversible degradation.

The primary objectives of this study were to quantify understory light availability in the eastern cottonwood plantation, and describe the photosynthetic light response of interplanted Nuttall oak (Quercus nuttallii Palm.) seedlings. Photosynthetic photon flux density (PPFD) measured in the understory of a 3-year-old, cottonwood plantation was 43% of full sunlight, and was sufficient to meet leaf saturation requirements over 29% of the diurnal cycle. Oak seedlings established in the cottonwood understory showed no change in blade area, and minimal shifts (<19%) in dry mass per unit area relative to open grown seedlings. A 19% decrease in dark respiration rate (R sub(d)) was measured on a leaf area basis, but gross photosynthesis (P sub(g-sat)), net photosynthesis (P sub(n-sat)), quantum yield (Q), light compensation point (LCP) and the saturation constant (K) of Nuttall oak leaves were not influenced by the presence of the cottonwood canopy, regardless of leaf area, mass or N content. P sub(n-sat) was strongly determined by foliar N concentration of seedlings in understory and open environments, increasing 1.2 mu mol m super(-2) s super(-1) for each 0.1% increase in N concentration. Our data indicate that Nuttall oak seedlings established beneath an eastern cottonwood canopy developed leaves with a capacity for carbon assimilation similar to open-grown plants. However, carbon assimilation by Nuttall oak may be sub-optimal on degraded sites where intensive row cropping has depleted soil N.

Secretion of microcin 24 provides an antibacterial defense mechanism for E. coli. In a plasmid-based system using transformed Salmonella enterica, we found that resistance to microcin 24 could be seen in concert with a multiple-antibiotic resistance phenotype. This multidrug-resistant phenotype appeared when Salmonella was exposed to an E. coli strain expressing microcin 24. Therefore, it appears that multidrug-resistant Salmonella can arise as a result of an insult from other pathogenic bacteria.

In comparison with the known CM neonate attractant, (E,E)- alpha -farnesene, ethyl (2E,4Z)-2,4-decadienoate was attractive at 10-fold and 1,000-fold lower threshold dosages in the Petri-plate and in the Y-tube bioassays, respectively. Methyl (2E,4Z)-2,4-decadienoate was attractive to CM neonates in these bioassays at much higher doses than ethyl (2 E,4 Z)-2,4-decadienoate. Other principal head-space volatiles from ripe pear fruit and pear leaves, including butyl acetate, hexyl acetate, (Z)-3-hexenyl acetate, and (E)- beta -ocimene, were not attractive to CM neonates. The potential uses of these pear kairomones for monitoring and control of CM in walnuts and apple are discussed.

AN - 17902044; 5163656 AB - Ethyl (2 E, 4 Z)-2,4-decadienoate, a pear-derived volatile, is a species-specific, durable, and highly potent attractant to the codling moth (CM), Cydia pomonella (L.), a serious pest of walnuts, apples, and pears worldwide. This kairomone attracts both CM males and virgin and mated females. It is highly attractive to CM in both walnut and apple orchard contexts, but has shown limited effectiveness in a pear orchard context. Rubber septa lures loaded with ethyl (2 E, 4 Z)-2,4-decadienoate remained attractive for several months under field conditions. At the same low microgram load rates on septa, the combined gender capture of CM in kairomone-baited traps was similar to the capture rate of males in traps baited with codlemone, the major sex pheromone component. The particular attribute of attracting CM females renders this kairomone a novel tool for monitoring population flight and mating-ovipositional status, and potentially a major new weapon for directly controlling CM populations.

We individually PIT-tagged 500 frogs during the summers of 1997 and 1998 and monitored these individuals during seven recapture surveys in 1997 and 15 recapture surveys in 1998 from the time they emerged from overwintering in July until the lakes froze for the winter in October. Probability of movement between lakes was associated with abundance of Hyla regilla larvae in the different lakes of origin, activity of the frogs (overwintering, breeding, feeding), and time of year. Overland movements exceeding 66 m were observed in 17% of the tagged frogs. Movement between lakes 1 km apart was detected. Site fidelity from 1997 to 1998 was high, and 97% of the tagged frogs recaptured in October of both years were found in the same overwintering lakes. Frogs were more narrowly distributed in spring and fall than in summer. Summer frog densities (number per meter of shoreline) were positively related to water temperature, air temperature, maximum lake depth, and presence of H. regilla larvae and negatively related to presence of trout. Mountain yellow-legged frogs use a range of aquatic sites throughout their activity period, and basins with a variety of deep lakes and shallow ponds may be the most appropriate reserves for this declining species.

AN - 70994194; 11445154 AB - The efficacy of a single whole-body spray of spinosad, a naturally derived control agent, applied at three concentrations was evaluated against cattle infested three separate times prior to treatment and at four weekly intervals following treatment with Boophilus microplus (Canestrini). At 0.0167% active ingredient (AI) both tick numbers (1894 ticks per calf) and index of fecundity (IF) of females (258.3) were no different than that of the control group. However, spinosad treatment at both 0.05 and 0.15% AI resulted in fewer ticks per calf (600 and 935, respectively) with lower IF values for females (43.4 and 38.4, respectively). The percent control of ticks on the animals at the time of treatment (acute efficacy) was dramatically lower at 0.0167% AI (21.4%) than at 0.05 (86.3%) and 0.15% AI (87.9%). Spinosad treatments appeared to be more effective against immature stages (nymphs and larvae) than against adult ticks that were on the animals at the time of treatment. The mean weight of females that survived to repletion was similar (322-348 mg) in all groups. By contrast, the mean weight of egg masses produced by females was highest in the control group (155 mg), whereas each increase in spinosad concentration resulted in a substantial decrease in egg mass weight, with the 0.15% AI group averaging only 73 mg. The hatch rate of eggs derived from females ranged from 93.4% in control females down to 53.9% hatch for females treated at 0.15% AI spinosad. The residual efficacy of spinosad at 0.0167% AI was poor even at 1 week following treatment, resulting in 101 ticks per calf and a level of control of only 66.4%. At 0.05% AI, protection against successful reinfestation was high at 1-week post-treatment where only five ticks per calf reached repletion, and control of the IF of these females was 99.3%. The 0.15% AI treatment provided almost complete protection against reinfestation for 2 weeks following treatment (99.9%. Thus, the use of spinosad at US ports-of-entry would be unacceptable because of the critical necessity of achieving 100% control with a single treatment to prevent the reintroduction of ticks. However, it is likely ticks could be eradicated using spinosad in tick infested areas of the US if repeated (systematic) treatments were applied to cattle maintained on the premises.

AN - 71051864; 11480626 AB - The objective was to determine pregnancy rate and stage of embryonic loss in response to grazing endophyte-free (E-; n = 20) or infected (E+; n = 30) tall fescue in postpartum beef cows with calves. Three weeks before estrus synchronization, cow-calf pairs were introduced to pastures (April 1999). Cows were synchronized and bred by AI after detected estrus for a period of 6 d and then by natural service for 62 d. Bulls were rotated weekly to minimize effects of fescue toxicosis on male fertility. Fetal development was monitored weekly between 30 and 60 d of pregnancy and at weaning using transrectal ultrasound. Respiration rate (52.0 +/- 1.4 vs 46.6 breaths/min; P 0.10) and occurred after environmental temperatures rose above 37.8 degrees C for three weeks. Total pregnancy losses that occurred by weaning (between 70 and 126 d of gestation) were 5.5 (E-) vs 17.6 (E+) +/- 8.0% (P > 0.10).

Such variations can be important for understanding the hydrologic system, and for evaluating the effectiveness of infiltration, runoff and sediment models. In this study, we investigated the sources of variability among 40 replications in a previously reported experiment on fallow plots located on a claypan soil in Missouri, USA. A numerical model was calibrated using data from the experiment and from other published data on the variability of soil properties. The results describe qualitatively the trend in the observed relationship between the coefficient of variation (CV) and mean runoff volume per event, as well as the lack of stability in time of the relative differences in runoff volume among plots. Quantitatively, approximately 50% of the observed coefficients of variation among the replicated plots were explained by the spatial variability of K sub(s), surface storage, and the depth to claypan. The remaining 50% may be due to the variability in rainfall among plots, measurement error in runoff, the fact that some published rather than site specific information was used in the analyses, and simplifications introduced in the modeling process. Our results suggested that changes in the relative differences in runoff volumes between plots during the season might be explained by the modification of the spatial distribution of K sub(s) and surface storage which occurs during tillage. The introduction of these sources of variability in the model formulation produced a realistic description of the variance of the observed values of runoff volume, as well as a relatively clear delineation between the explained and unexplained variability. The results may also serve as an index of model performance in predicting observed data.

AN - 71167442; 11553232 AB - Salmonella enterica serovar Enteritidis is the cause of the food-borne salmonellosis pandemic in humans, in part because it has the unique ability to contaminate eggs without causing discernible illness in the birds infected. The infection route to humans involves colonization, survival and multiplication of the pathogen in the hen house environment, the bird and, finally, the egg. This review highlights the stages of transmission and discusses evidence that altered bacterial growth patterns and specific cell surface characteristics contribute to the adaptation of S. enteritidis to these diverse environments.

Urine and faeces were collected daily for 96 h, while blood was sampled at multiple time points. Tissues were removed for combustion analysis. 2. Each tissue contained < 0.65 of the dose at 96h. Tissues with highest levels of 1278-TCDD, as a percentage of administered dose, were the large and small intestine, rumen, liver and carcass. 3. Urinary excretion accounted for 10.6% of the dose, and faecal excretion accounted for 81.6% of the administered dose. The major urinary and faecal metabolites were isolated and characterized by mass spectrometry and 1H-NMR. 4. Plasma levels of 14C peaked at 24h, and decreased to near background at 96 h. Detectable plasmal levels of 1278-TCDD were observed by 2 h. 5. A hydroxylated metabolite of 1278-TCDD was detected in calf plasma, which has the potential to interfere with thyroid hormone homeostasis.

AN - 71058929; 11476506 AB - Soil fumigation using shank injection creates high fumigant concentration gradients in soil from the injection point to the soil surface. A temperature gradient also exists along the soil profile. We studied the degradation of methyl isothiocyanate (MITC) and 1,3-dichloropropene (1,3-D) in an Arlington sandy loam (coarse-loamy, mixed, thermic Haplic Durixeralf) at four temperatures and four initial concentrations. We then tested the applicability of first-order, half-order, and second-order kinetics, and the Michaelis-Menten model for describing fumigant degradation as affected by temperature and initial concentration. Overall, none of the models adequately described the degradation of MITC and 1,3-D isomers over the range of the initial concentrations. First-order and half-order kinetics adequately described the degradation of MITC and 1,3-D isomers at each initial concentration, with the correlation coefficients greater than 0.78 (r2> 0.78). However, the derived rate constant was dependent on the initial concentration. The first-order rate constants varied between 6 and 10x for MITC for the concentration range of 3 to 140 mg kg(-1), and between 1.5 and 4x for 1,3-D isomers for the concentration range of 0.6 to 60 mg kg(-1), depending on temperature. For the same initial concentration range, the variation in the half-order rate constants was between 1.4 and 1.7x for MITC and between 3.1 and 6.1x for 1,3-D isomers, depending on temperature. Second-order kinetics and the Michaelis-Menten model did not satisfactorily describe the degradation at all initial concentrations. The degradation of MITC and 1,3-D was primarily biodegradation, which was affected by temperature between 20 and 40 degrees C, following the Arrhenius equation (r2 > 0.74).

AN - 71055023; 11476510 AB - Phosphorus (P) in irrigation runoff may enrich offsite water bodies and streams and be influenced by irrigation water quality and antecedent soil surface conditions. Runoff, soil loss, and P fractions in runoff using reverse osmosis (RO) water or mixed RO and well water (RO/ Tap) were studied in a laboratory sprinkler study to evaluate water source effects on P transport. A top- or subsoil Portneuf silt loam (coarse-silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid), either amended or not amended with manure and/or with cheese whey, with Olsen P from 20 to 141 mg kg(-1) and lime from 108 to 243 g kg(-1), was placed in 1.5 x 1.2 x 0.2-m-deep containers with 2.4% slope and irrigated three times from a 3-m height for 15 min, applying 20 mm of water. The first irrigation was on a dry loose surface, the second on a wet surface, and the third on a dry crusted surface. Surface (ca. 2 cm) soil samples, prior to the first irrigation, were analyzed for Olsen P, water-soluble P (Pws), and iron-oxide impregnated paper-extractable P (FeO-P) analyses. Following each irrigation we determined runoff, sediment, dissolved reactive phosphorus (DRP) in a 0.45-microm filtered sample, and FeO-P and total P in unfiltered samples. Soil surface conditions had no effect on P runoff relationships. Water source had no significant effect on the relationship between DRP or FeO-P runoff and soil test P, except for DRP in RO runoff versus water-soluble soil P (r2 = 0.90). Total P in RO runoff versus soil P were not related; but weakly correlated for RO/Tap (r2 < 0.50). Water source and soil surface conditions had little or no effect on P runoff from this calcareous soil.

AN - 71048037; 11476505 AB - The half-lives, degradation rates, and metabolite formation patterns of atrazine (6-chloro-N2-ethyl-N4-isopropyl-1,3,5-triazine-2,4-diamine) and metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl) acetamide] were determined in an anaerobic wetland soil incubated at 24 degrees C for 112 d. At 0, 7, 14, 28, 42, 56, and 112 d, the soil and water were analyzed for atrazine and metolachlor, and their major metabolites. The soil oxidation-reduction potential reached -200 mV after 14 d. Degradation reaction rates were first-order for atrazine in anaerobic soil and for metolachlor in the aqueous phase. Zero-order reaction rates were best fit for atrazine in the aqueous phase and metolachlor in anaerobic soil. In anaerobic soil, the half-life was 38 d for atrazine and 62 d for metolachlor. In the aqueous phase above the soil, the half-life was 86 d for atrazine and 40 d for metolachlor. Metabolites detected in the anaerobic soil were hydroxyatrazine and deethylatrazine for atrazine, and relatively small amounts of ethanesulfonic acid and oxanilic acid for metolachlor. Metabolites detected in the aqueous phase above the soil were hydroxyatrazine, deethylatrazine, and deisopropylatrazine for atrazine, and ethanesulfonic acid and oxanilic acid for metolachlor. Concentrations of metabolites in the aqueous phase generally peaked within the first 25 d and then declined. Results indicate that atrazine and metolachlor can degrade under strongly reducing conditions found in wetland soils. Metolachlor metabolites, ethanesulfonic acid, and oxanilic acid are not significantly formed under anaerobic conditions.

AN - 71045060; 11456207 AB - Most traditional Campylobacter detection and enumeration procedures are difficult and time consuming. Estimations of Campylobacter populations by the most probable number (MPN) method are especially laborious. The objective of this collaborative study, performed in duplicate in Agricultural Research Service and Food Safety Inspection Service laboratories, was to compare two MPN procedures (utilizing different selective enrichment broths and plating media) to the direct plating technique for enumeration of Campylobacter from freshly processed (postchill, postdrip) broiler chicken carcasses. Results obtained from the direct plating of carcass rinse samples on Campy-cefex agar were not significantly different (P > 0.05) from an MPN procedure employing Hunt's Campylobacter selective enrichment broth followed by recovery on modified Campylobacter charcoal differential agar. However, both of these procedures provided significantly (P < 0.05) better recovery than a second MPN procedure using Rosef's selective enrichment broth followed by plating on Mueller-Hinton blood agar with antibiotics. The direct plating method offers a more simple, less expensive, more rapid alternative to traditional MPN procedures for estimating Campylobacter populations associated with freshly processed broiler carcasses.

From 1996 through 1999, we measured yield and NO3 loss from a subsurface drained field in central Iowa at three N fertilizer rates: a low (L) rate of 67 kg ha(-1) in 1996 and 57 kg ha(-1) in 1998, a medium (M) rate of 135 kg ha(-1) in 1996 and 114 kg ha(-1) in 1998, and a high (H) rate of 202 kg ha(-1) in 1996 and 172 kg ha(-1) in 1998. Corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] were grown in rotation with N fertilizer applied in the spring to corn only. For the L treatment, NO3 concentrations in the drainage water exceeded the 10 mg N L(-1) maximum contaminant level (MCL) established by the USEPA for drinking water only during the years that corn was grown. For the M and H treatments, NO3 concentrations exceeded the MCL in all years, regardless of crop grown. For all years, the NO3 mass loss in tile drainage water from the H treatment (48 kg N ha(-1)) was significantly greater than the mass losses from the M (35 kg N ha(-1)) and L (29 kg N ha(-1)) treatments, which were not significantly different. The economically optimum N fertilizer rate for corn was between 67 and 135 kg ha(-1) in 1996 and 114 and 172 kg ha(-1) in 1998, but the net N mass balance indicated that N was being mined from the soil at these N fertilizer levels and that the system would not be sustainable.

AN - 71017793; 11452585 AB - One of the principal uses of the fungicide, chlorothalonil, is control of foliar peanut diseases. Recent assessments indicate its runoff from treated fields in southeastern states presents risks to aquatic life. Two factors that control its runoff are how much reaches soil surfaces and degradation rates. To address these questions and to evaluate accumulation and decay of key metabolites, soil samples (0-2 cm) were collected after seven chlorothalonil applications on experimental peanut plots in south central Georgia during the 1999 growing season. At the start of and during laboratory incubations, samples were analyzed for the parent and degradates by HPLC-PDA-APCI-MS. The maximum observed residue levels were after the second application, after which canopy closure reduced soil deposition from later applications to 5-10% of applied amounts. After the last spray, < 5% of the cumulative chlorothalonil applied was detected in the soil. Foliar interception and dissipation and rapid soil degradation contributed to low residue levels. Soil half-lives were < 1-3.5 days for chlorothalonil and 10-22 days for its principal degradate, 4-hydroxychlorothalonil. Other daughter and granddaughter products were detected, some of which accumulated during the growing season. Results emphasize the plant canopy role in controlling the amount of fungicide sprays that reach soil surfaces and suggest concentration-dependent chlorothalonil degradation with degradation rates increasing as soil loading decreases. The study indicates that the 30-day field half-life often used for risk assessments of this pesticide is too long for one of its most important agronomic uses, i.e., in southeastern peanut production. It also indicates that the principal metabolites are more persistent than the parent, and more study is needed to identify and quantify their fate pathways.

AN - 70984995; 11444292 AB - This study was conducted to evaluate the effect of hairy vetch cover crop residue on runoff losses of atrazine and metolachlor under both no-till corn field plots and from a laboratory runoff system. A 2-year field study was conducted in which losses of atrazine and metolachlor from vetch and non-vetch field plots were determined from the first runoff event after application (5 and 25 days after application in 1997 and 1998, respectively). A laboratory study was conducted using soil chambers, designed to simulate field soil, water, vegetation, and herbicide treatment conditions, subjected to simulated rain events of 5, 6, 20 and 21 days after application, similar to the rainfall pattern observed in the field study. Atrazine losses ranged from 1.2 to 7.2% and 0.01 to 0.08% and metolachlor losses ranged from 0.7 to 3.1% and 0.01 to 0.1% of the amount applied for the 1997 and 1998 runoff events, respectively. In the laboratory study, atrazine runoff losses ranged from 6.7 to 22.7% and 4.2 to 8.5% and metolachlor losses ranged from 3.6 to 9.8% and 1.1 to 4.7% of the amount applied for the 5-6 and 20-21 day events, respectively. The lower losses from the field study were due to smaller rainfall amounts and a series of small rains prior to the runoff event that likely washed herbicides off crop residue and into soil where adsorption could occur. Runoff losses of both herbicides were slightly higher from non-vetch than vetch field plots. Losses from the laboratory study were related to runoff volume rather than vegetation type.

AN - 70984524; 11425748 AB - Agricultural soils are typically fumigated to provide effective control of nematodes, soilborne pathogens, and weeds in preparation for planting of high-value cash crops. The ability of soil microbial communities to recover after treatment with fumigants was examined using culture-dependent (Biolog) and culture-independent (phospholipid fatty acid [PLFA] analysis and denaturing gradient gel electrophoresis [DGGE] of 16S ribosomal DNA [rDNA] fragments amplified directly from soil DNA) approaches. Changes in soil microbial community structure were examined in a microcosm experiment following the application of methyl bromide (MeBr), methyl isothiocyanate, 1,3-dichloropropene (1,3-D), and chloropicrin. Variations among Biolog fingerprints showed that the effect of MeBr on heterotrophic microbial activities was most severe in the first week and that thereafter the effects of MeBr and the other fumigants were expressed at much lower levels. The results of PLFA analysis demonstrated a community shift in all treatments to a community dominated by gram-positive bacterial biomass. Different 16S rDNA profiles from fumigated soils were quantified by analyzing the DGGE band patterns. The Shannon-Weaver index of diversity, H, was calculated for each fumigated soil sample. High diversity indices were maintained between the control soil and the fumigant-treated soils, except for MeBr (H decreased from 1.14 to 0.13). After 12 weeks of incubation, H increased to 0.73 in the MeBr-treated samples. Sequence analysis of clones generated from unique bands showed the presence of taxonomically unique clones that had emerged from the MeBr-treated samples and were dominated by clones closely related to Bacillus spp. and Heliothrix oregonensis. Variations in the data were much higher in the Biolog assay than in the PLFA and DGGE assays, suggesting a high sensitivity of PLFA analysis and DGGE in monitoring the effects of fumigants on soil community composition and structure. Our results indicate that MeBr has the greatest impact on soil microbial communities and that 1,3-D has the least impact.

AN - 70982553; 11423146 AB - Studying lignin-biosynthetic-pathway mutants and transgenics provides insights into plant responses to perturbations of the lignification system, and enhances our understanding of normal lignification. When enzymes late in the pathway are downregulated, significant changes in the composition and structure of lignin may result. NMR spectroscopy provides powerful diagnostic tools for elucidating structures in the difficult lignin polymer, hinting at the chemical and biochemical changes that have occurred. COMT (caffeic acid O-methyl transferase) downregulation in poplar results in the incorporation of 5-hydroxyconiferyl alcohol into lignins via typical radical coupling reactions, but post-coupling quinone methide internal trapping reactions produce novel benzodioxane units in the lignin. CAD (cinnamyl alcohol dehydrogenase) downregulation results in the incorporation of the hydroxycinnamyl aldehyde monolignol precursors intimately into the polymer. Sinapyl aldehyde cross-couples 8-O-4 with both guaiacyl and syringyl units in the growing polymer, whereas coniferyl aldehyde cross-couples 8-O-4 only with syringyl units, reflecting simple chemical cross-coupling propensities. The incorporation of hydroxycinnamyl aldehyde and 5-hydroxyconiferyl alcohol monomers indicates that these monolignol intermediates are secreted to the cell wall for lignification. The recognition that novel units can incorporate into lignins portends significantly expanded opportunities for engineering the composition and consequent properties of lignin for improved utilization of valuable plant resources.

AN - 70942700; 11420248 AB - The objective of the experiment was to examine the interaction of endophyte-infected tall fescue and environmental temperature on follicular and luteal development and function in beef heifers. Heifers were fed endophyte-free or endophyte-infected tall fescue seed at thermoneutral or heat stress temperatures (n = 6/treatment) 4 wk before and 3 wk after synchronized ovulation. All heifers were subjected to thermoneutral conditions (19 degrees C, 50% relative humidity) from Days -7 to -2; temperature increased incrementally from Days -1 to 0 and cycled between 25 degrees C and 31 degrees C between Days 1 and 20 for heat-stressed heifers. Serum was collected and ovaries monitored every other day after induced luteolysis between Days 1 and 23 or until ovulation. Size and location of follicles >4 mm and corpora lutea were recorded. Serum concentrations of prolactin were reduced in heat-stressed heifers fed infected seed and both heat stress and infected seed decreased total cholesterol. Rectal temperature and respiration rate were greatest in heifers fed the infected seed when exposed to maximal temperatures. Heat stress led to reduced diameter of the corpus luteum and serum progesterone compared with thermoneutral conditions. Progesterone was reduced more so in heifers fed infected seed. The combination of infected seed and heat stress was associated with reduced diameter of the preovulatory dominant follicle, and consumption of infected seed led to fewer large follicles during the estrous cycle. Both stressors led to reduced serum estradiol. Impaired follicle function may explain reduced pregnancy rates commonly observed in heifers grazing infected tall fescue pasture.

AN - 70929956; 11394789 AB - To understand the effects of diffuse pollution information on the source of pollutants, quantities in transport, mode of transport, transient nature of the pollution event, and most importantly, a consideration of remediation efforts need to be known. For example, water quality research in the Yazoo Basin uplands in Mississippi has shown sediment loads from a conventional-till upland soybean watershed to be about 19,000kg/ha/yr, and responsible for 77-96% of P and N in transport. In contrast, sediment loads from a comparable no-till soybean watershed were only 500 kg/ha/yr. transporting about 31% of P and N in transport. Sediment loads from a nearby forested area were low, about 200 kg/ha/yr, but responsible for about 47-76% of P and N in transport. Transient pollution events are responsible for the transport of large quantities of sediment, nutrients, and pesticides; in some storm events nearly the annual load. Best management practices (BMPs) must be designed to remediate diffuse pollution and the transient nature of pollution events which can have a profound effect on the ecological health of steams and reservoirs.

Restorationists working in most tropical settings are usually hampered by lack of basic information on the wide variety of native tree species that characterize the pre-disturbance forests, as well as insufficient understanding of the ecology of disturbance and natural recovery to design effective restoration programs. A notable exception to this is the forest restoration program developed since the early 1980s by a Brazilian bauxite mining company operating at Trombetas in Para State in central Amazonia. A systematic nursery and field research strategy was used to develop a reforestation program based on mixed plantings of more than 70 native old-growth forest tree species. This technique has been used to replant about 100 ha of deforested minelands each year over the past 15 years. Research in recent years has evaluated this approach and other, generally simpler, reforestation methods used at a smaller scale at this site. Post-plantation biodiversity development and other indicators of restoration success or sustainability were recorded. The results of these studies have shown the overwhelming importance of careful site preparation and topsoil handling/replacement practices in determining both future productivity and biodiversity of the redeveloping forests, irrespective of the complexity of the planting design used. The inclusion of a wide variety of forest species, particularly later successional species, was very important for long-range restoration owing to limitations on natural recovery processes that inhibit seed dispersal and subsequent colonization of many old-growth forest species. Many of the lessons learned at this site are applicable to improve the design of mineland rehabilitation and forest restoration programs worldwide.

A quantitative approach based on work by Laumann and Knoke [The Organizational State (1987)] was utilized in conjunction with the Delphi method. Results suggest that the parity in the distribution of influence among network sectors means that moving the issue of sustainable forestry onto the formal policy agenda will require more consensus on problems and solutions than exists at the present time. Accordingly, broad policy actions resulting from the expansion of the issue of sustainable forestry are unlikely in the short-term. However, experts on the Delphi panel anticipate that changes will occur in response to sustainability issues. At the federal and state level, this is likely to result in changes to public forest management and to the objectives assigned to the USDA Forest Service and to the state forestry agencies. States are projected to draft new and to change old private forest practices regulations as a result of sustainable forestry concerns. In the private sector, the trend of applying criteria and indicator-based sustainable forestry management standards and certification programs will continue. Non-industrial private forest owners are projected to make the fewest direct accommodations. Finally, where directly comparable, the Delphi study's results were not significantly different from the quantitative approach, suggesting that Delphi has promise for network research applications.

Exposure to protective or detrimental factors during this period may influence peak bone mass attainment and subsequent development of osteoporosis. In order to evaluate the association of body size during adolescence with subsequent adult bone mass, we conducted a follow-up study of a community-based cohort of girls who participated in a growth and sexual maturation study 30 years ago. Data from the original study included age at menarche, height at menarche and weight at menarche. Follow-up evaluation of 119 subjects, now premenopausal women ages 40-45 years, included bone mineral density (BMD) measurements of the total body, lumbar spine, femoral neck, total hip, and ultradistal radius by dual-energy X-ray absorptiometry. After adjustment for current adult weight and other factors related to bone mass, weight at menarche was found to be positively associated with subsequent adult BMD. Similarly, body mass index (BMI) at menarche was positively associated with adult BMD. In contrast, age at menarche was not found to predict adult BMD. When the subjects were divided into quartiles based on their BMI at menarche, subjects in the lowest quartile of BMI at menarche had adult mean BMD that was 8-15% lower at the measured sites compared with subjects in the highest quartile of BMI at menarche. In conclusion, low body weight and low BMI at menarche appear to be significant predictors of reduced bone mass in healthy premenopausal women ages 40-45 years.

We tested 30 market-bound pigs (about 240 lb [110 kg]) on each of 10 occasions from an Iowa farrow-to-finish operation with about 600 sows. All pigs were slaughtered, and samples were collected at a large Midwest abattoir. On the farm, fecal samples were collected for culture of Salmonella. Pigs were alternately assigned to a lairage treatment (holding in a clean, disinfected facility at the National Animal Disease Center) group or a control group (remaining on the farm). After about 18 h, both groups were transported (about 137 km) to a large Midwest abattoir, commingled, and slaughtered. After slaughter, samples were collected for culture of Salmonella (feces from the distal colon, ileocecal lymph nodes, cecal contents, ventral thoracic lymph nodes, subiliac lymph nodes, and carcass swabs). Diaphragm sections were collected for serum ELISA. Salmonella enterica Derby was the only serotype isolated from farm fecal samples (3.4%, 10 of 290). Multiple serotypes (n = 17) were isolated from 71.8% (196 of 273) of the pigs when abattoir-collected samples were cultured: cecal contents (21.2%, 58 of 273), distal colon contents (52%, 142 of 273), and ileocecal lymph nodes (43.6%, 119 of 273). There were lower Salmonella isolation rates from the lairaged pigs (P < 0.05). The predominant serotype isolated at the abattoir varied by week of the study. This study suggests that pigs became internally contaminated with Salmonella after leaving the farm, possibly while in the abattoir holding pens, and that 18 h lairage, in clean facilities, does not increase shedding.

In this study, a transgene construct flanked by oppositely oriented lox sites was co-bombarded into maize cells along with a cre-expressing construct. From analysis of the regenerated plants, a high percentage of the primary transformants harbored a single copy of the introduced transgene, and among these, a majority also lacked the cre construct. We deduce that the expression of cre must have contributed to resolving concatemeric molecules either prior to or after DNA integration into the maize genome.

Evaluation of the vaccine's safety in non-target species was considered necessary prior to field use. Between June 1998 and December 1999, ground squirrels (Spermnophilus richardsonii, n = 21), deer mice (Pcromyscus maniculatus, n = 14), prairie voles (Microtus ochrogaster, n = 21), and ravens (Corvus corax, n = 13) were orally inoculated with SRB51 or physiologic saline. Oral and rectal swabs and blood samples were collected for bacteriologic evaluation, Rodents were necropsied at 8 to 10 wk and 12 to 21 wk post inoculation (PI), and ravens at 7 and 11 wk PI. Spleen, liver and reproductive tissues were collected for bacteriologic, and histopathologic evaluation. No differences in clinical signs, appetite, weight loss or gain, or activity were observed between saline- and SRB51-inoculated animals in all four species. Oral and rectal swabs from all species were negative throughout the study. In tissues obtained from SRB51-inoculated animals, the organism was isolated from six of seven (86%) ground squirrels, one of six (17%) deer mice, none of seven voles, and one of five (20%) ravens necropsied at 8, 8, 10, and 7 wk PI, respectively, Tissues from four of seven (57%) SRB51-inoculated ground squirrels were culture positive for the organism 12 wk PI; SRB51 was not recovered from deer mice, voles, or ravens necropsied 12, 21, or 11 wk, respectively, PI. SRB51 was not recovered from saline-inoculated ground squirrels, deer mice, or voles at any time but was recovered from one saline-inoculated raven at necropsy, 7 wk PI, likely attributable to contact with SRB51-inoculated ravens in an adjacent aviary room. Spleen was the primary tissue site of colonization in ground squirrels, followed by the liver and reproductive organs. The results indicate oral exposure to SRB51 does not produce morbibity or mortality in ravens, ground squirrels, deer mice, or prairie voles.

(type strain NRRL YB-4811, CBS 8849), is described; it was isolated from Kombucha tea, a popular fermented tea-based beverage. The four known strains of the new species have identical nucleotide sequences in domain D1/D2 of 26S rDNA. Phylogenetic analysis of D1/D2 and 18S rDNA sequences places Z. kombuchaensis near Zygosaccharomyces lentus. The two species are indistinguishable on standard physiological tests used for yeast identification, but can be recognized from differences in restriction fragment length polymorphism patterns obtained by digestion of 18S-ITS1 amplicons with the restriction enzymes DdeI and MboI.

We also documented Field Sparrow morning nest arrival times during the laying period, because Field Sparrows appear to desert nests in response to encounters with laying female cowbirds. Field Sparrows responded most aggressively to cowbird models and arrived the earliest in Illinois, where they were most heavily parasitized. Field Sparrows responded the least to models in Pennsylvania, where they are almost never parasitized. Our results suggest that those host behaviors result from some aspect of host-cowbird interactions, but the extent to which such behaviors are genetic or learned needs further study.

Mean total leaf weight consumed by larvae was highest in cabbage (2.7 g) and lowest in pigweed (1.6 g). The feeding index (pupal weight divided by total weight of leaf tissue consumed) was highest on pigweed, followed by cotton, pepper, sunflower, and cabbage. On all host plants, significant relationships were found between amount of leaf tissue consumed and resulting pupal weight. Likewise, significant relationships were found between pupal weight and subsequent adult fecundity on all host plants. The highest percentage of female progeny was recorded in S. exigua reared on pigweed (62.2%) and the lowest for larvae reared on cabbage (43.6%). Duration of the larval stage was shortest on pigweed (12.4 d) and longest on pepper (18.0 d). Larval survival was highest on pigweed (94.4%) and lowest on cabbage (67.1%). Three key statistics were used to assess performance of S. exigua on the different host plants: 1) feeding index, 2) intrinsic rate of increase, r; and 3) growth index (percentage immature survival divided by immature development time). Using these measures, S. exigua performance was best on pigweed, worst on cabbage, and intermediate on cotton, pepper, and sunflower. We discuss the implications of these findings for control of S. exigua..

S. A. , with and without an introduced piscivorous fish, the Sacramento pikeminnow, Ptychocheilus grandis. We also measured mortality of tethered prickly sculpin in a field experiment including river, habitat type (pools versus riffles) and cover as factors. Average sculpin density (C. aleuticus and C. asper combined) in two rivers without pikeminnow was 21 times higher than the average density in two rivers in a drainage with introduced pikeminnow. In riffles, differences in the density of sculpins among rivers could be linked to differences in cover. However, riffles in rivers without pikeminnow had an average sculpin density 77 times higher than rivers with pikeminnow, yet only nine times more cover. In pools, cover availability did not differ among rivers, but the density of sculpins in rivers without pikeminnow was 11 times higher than rivers with pikeminnow. In the field experiment, mortality of tethered sculpin varied substantially among treatments and ANOVA indicated a significant River x Habitat x Cover interaction (P < 0. 001). Overall, tethered prickly sculpin suffered 40% mortality over 24 h in rivers with pikeminnow and 2% mortality in rivers without pikeminnow, suggesting that predation is the mechanism by which the pikeminnow affects sculpins. The apparent reduction in sculpin abundance by introduced pikeminnow has probably significantly altered food webs and nutrient transport processes, and increased the probability of extinction of coastrange and prickly sculpins in the Eel River drainage.

An infiltration-based submodel similar to that used in WEPP was dynamically linked to the SPUR2.4 rangeland ecosystem model to provide the framework for future model enhancement and investigation of the impacts of management on the rangeland ecosystem. Model description and documentation of model modifications are presented for SPUR 2000. A sensitivity analysis and initial test of SPUR 2000 were performed using rainfall simulation plot and micro-watershed data from Idaho sagebrush rangeland. The sensitivity analysis showed improved sensitivity of runoff and erosion to various vegetation parameters. The long-term simulations demonstrated good representation of soil water content, peak standing crop, and evapotranspiration. SPUR 2000 did a better job of predicting individual thunderstorm runoff events, and estimated 15-year runoff within 12% compared to SPUR2.4, which grossly overestimated runoff. Neither model accurately predicted sediment loss, but predicted values did demonstrate the relatively small amount of erosion that occurs from these rangelands. Neither model could reasonably estimate the snow-driven runoff that dominates these types of western rangelands. Additional research needs to explore the degree of influence that vegetation has on infiltration and runoff and how it varies for different plant communities. Development of specific K sub(e) estimation equations based on this information will strengthen the vegetation-hydrology linkage within the model.

However, the State's ground water is very susceptible to contamination because of the very permeable soils in many areas, relatively shallow depth to ground water, and high average annual rainfall. Only limited research has been conducted in the State concerning agrichemical movement in shallow ground water. This is especially true of the loessial uplands of north Mississippi with its restrictive layer soils. Thus, the purpose of this study was to compare the movement in shallow ground water of atrazine and alachlor (2-chloro-2',6'-diethyl-N-methoxymethylacetanilide), each applied in two different formulations (EC and CR), in upland corn production under two tillage practices (NT and CT).

AN - 18176860; 5158208 AB - The effect of inhibitors of pyridoxal-5'-phosphate-dependent enzymes (IPEs) on cysteine synthase (CS; EC 4.2.99.8), which synthesizes cysteine from O-acetylserine and sulfide, was examined. CS was extracted from the leaves of Echinochloa crus-galli L., fractionated with 30-70% ammonium sulfate, and then used for the enzyme assay with seven IPEs. When substrates of CS and 10 mM IPEs were added simultaneously, -allylglycine, -propargylglycine, beta -chloro--alanine, 3-bromopropionate, amino-oxyacetate (AOA), and hydroxylamine inhibited CS by 64, 45, 62, 61, 89, and 33%, respectively. All the IPEs inhibited shoot elongation of E. crus-galli in a seedling growth bioassay; however, there was a very low correlation between the inhibition of CS and that of shoot elongation (R super(2) = 0.173). When CS was preincubated with 10 mM IPEs at 30 degree C for 1 h, -allylglycine, -propargylglycine, beta -chloro--alanine, 3-bromopropionate, AOA, and hydroxylamine inhibited CS by 47, 27, 49, 40, 96, and 98%, respectively. CS inhibition by AOA and hydroxylamine increased during the preincubation period, suggesting that AOA and hydroxyamine might be irreversible inhibitors of CS. The correlation coefficient between CS inhibition by preincubation and inhibition of shoot elongation was R super(2) = 0.630. These results suggest that CS inhibition in E. crus-galli might affect its growth. Copyright 2001 Academic Press.

Three antibody sandwich formats were tested: commercial anti-O157:H7 IM beads, IM beads made in-house with a polyclonal anti-O157:H7 immunoglobulin G (IgG), or IM beads made in-house with a monoclonal anti-O157:H7 IgG coupled with a polyclonal anti-O157:H7 IgG to which an electrochemiluminescent label (TAG) was attached. The monoclonal IM bead-polyclonal TAG format was chosen for optimization because it gave lower background levels and linear regression slopes of ca. 1.0, indicative of a constant ECL signal per cell. The dynamic range was ca. 10 to 10 cells ml super(-1) in phosphate-buffered saline and in raw water samples. The monoclonal IM beads selectively captured E. coli O157 cells in the presence of ca. 10 cells of a non-O157 strain of E. coli ml super(-1). Background ECL signals from concentrated (100-fold) water samples were substantially higher and more variable than raw water samples. The background signal was partially eliminated by the addition of polyvinylpolypyrrolidone. Successive cell capture incubations, termed sequential bead capture (SBC), were optimized for establishing baseline ECL values for individual water samples. The linear dynamic range with SBC was ca. 10 to 10 E. coli O157 cells ml of concentrated water super(-1). To validate the protocol, 10-liter surface water samples were spiked with ca. 5,000 E. coli O157 (Odwalla) cells and concentrated by vortex filtration, and 1- or 3-ml aliquots were analyzed by IM-ECL. Differential ECL signals (SBC) from 1- and 3-ml samples were statistically significant and were generally consistent with standard curves for these cell concentrations. Enrichments were conducted with aliquots of spiked raw water and concentrated water using EC broth and minimal lactose broth (MLB). All tubes with concentrated water became turbid and gave a positive ECL response for E. coli O157 (>10,000 ECL units); MLB gave a somewhat higher detection rate with spiked raw water. The potential sensitivity of the IM-ECL assay is ca. 25 E. coli O157 cells ml of raw water super(-1), 25 cells 100 ml of 100-fold concentrated water super(-1), or 1 to 2 viable cells liter super(-1) with concentration and enrichment. The IM-ECL assay appears suitable for routine analysis and screening of water samples.

Escherichia colimetabolizes a wide range of substrates and has been engineered to produce ethanol in high yield from sugar mixtures. E. coli metabolizes glucose in preference to other sugars and, as a result, utilization of the pentoses in hemicellulose-derived sugar mixtures is delayed and may be incomplete. Residual sugar lowers the ethanol yield and is problematic for downstream processing of fermentation products. Therefore, a catabolite repression mutant that simultaneously utilizes glucose and pentoses would be useful for fermentation of complex substrate mixtures. We constructed ethanologenic E. coli strains with a glucose phosphotransferase (ptsG) mutation and used the mutants to ferment glucose, arabinose, and xylose, singly and in mixtures, to ethanol. Yields were 87-94% of theoretical for both the wild type and mutants, but the mutants had an altered pattern of mixed sugar utilization. Phosphotransferase mutants metabolized the pentoses simultaneously with glucose, rather than sequentially. Based upon fermentations of sugar mixtures, a catabolite-repression mutant of ethanologenic E. coli is expected to provide more efficient fermentation of hemicellulose hydrolysates by allowing direct utilization of pentoses.

These studies, regarding oxygen uptake, have all been undertaken from the perspective of the host plant cell reacting to the invading pathogen. In contrast, here we describe and characterize an increase in oxygen uptake by bacterial cells in response to plant suspensions or autoclaved plant cell filtrates. Autoclaved plant cell filtrates stimulated bacterial oxygen uptake by as much as seven-fold within a few minutes after addition. This oxygen uptake response was proportional to both the concentration of the plant cell filtrate and the concentration of the bacteria. KCN inhibited the bacterial response, suggesting that bacterial respiration may be involved. Unlike the plant oxygen uptake response to bacteria, there was no concurrent H sub(2)O sub(2) accumulation and the NADPH oxidase inhibitor, DPI, had no effect on the bacterial response. Streptomycin, an inhibitor of bacterial protein synthesis, inhibited the bacterial oxygen uptake response to the plant cell filtrate. K-252, a protein kinase inhibitor that strongly inhibits the plant oxygen uptake response to bacteria, had no effect upon the bacterial oxygen uptake response. When potato /bacterial cell suspensions were pretreated with either streptomycin or K-252, the combined plant/bacterial oxygen uptake response was inhibited by 15 or 70%, respectively. This indicates that as much as 15-30% of the increased oxygen consumption during plant suspension cell/bacteria interactions may be attributable to bacteria, which comprise less than 1% of the total cell mass.

Efforts to control the snake population have included trapping using live mouse lures, but for logistical and economic reasons a synthetic lure is needed. When searching for live food, brown treesnakes use both visual and odor cues. However, when searching for carrion, odor cues are sufficient. Attempts to develop synthetic lures based on chemical reconstruction of the complex carrion odor have not succeeded. We provide evidence that a microbial-substrate interaction is important for bait take by brown treesnakes. Microbial cultures taken from mouse carrion indicate that Enterobacter agglomerans is the predominant bacterium, and field tests suggest that this organism may be important to odor production that attracts brown treesnakes. This information may prove useful in the development of microbial-based biological reactors that could be formulated to produce a continuous stream of odor of sufficient complexity so as to be attractive to foraging snakes.

Newly identified attractants included syn-benzaldoxime, especially for NCR, and beta -caryophyllene for WCR females. ( plus or minus )-Linalool was more effective than was (-)-linalool. Myrcene, (+)- beta -pinene, and (-)- beta -pinene were unattractive. Adding methyl salicylate to ( plus or minus )-linalool, (+)- alpha -terpineol, or beta -ionone appeared to synergistically increase capture of WCR females, but dispensing the terpenes in binary blends did not. Dose-response data for methyl salicylate, ( plus or minus )-linalool, and a blend of both compounds confirmed the synergy. beta -Caryophyllene, but not (-)- alpha -pinene, added to the latter blend produced a further synergistic increase in WCR female capture that did not vary with sesquiterpene dose from 1.0 to 100 mg. Indole addition to the same blend caused an increase in WCR female captures indicative of synergy, assuming that each did not individually lure different segments of the WCR female population. The green leaf volatiles (Z)-3-hexenyl acetate and (Z)-3-hexen-1-ol were unattractive alone and had no influence on efficacy of traps baited with 3.3 mg each of ( plus or minus )-linalool, methyl salicylate, and beta -caryophyllene. The latter mixture captured about half as many WCR females as did 10 mg of 4-methoxycinnamaldehyde, a potent WCR attractant standard. Substituting beta -ionone for ( plus or minus )-linalool yielded a ternary blend that captured more beetles than did the aldehyde and was unaffected by aldehyde addition. Olive oil, which has been used to sustain attractant volatilization, did not affect captures. The results show that the blending of maize volatiles has the potential to greatly improve efficacy of lures having promising applications in corn rootworm population management.

Attractants for swarms include the odors of old dark honey bee brood combs, odors from noncomb hive materials and propolis, and Nasonov pheromone, the odor released from the Nasonov glands of worker bees. Based on crossover and choice test experiments, swarms were shown to prefer, among otherwise identical cavities, those cavities containing Nasonov pheromone over cavities with only comb or other hive odors, cavities containing old comb over those with only noncomb odors or propolis, and cavities containing noncomb odors or propolis over those without bee or hive odor. Synergy between odors was not observed; that is, comb and/or noncomb hive odors did not enhance the attractiveness of Nasonov pheromone. The data support a model based on a hierarchy of olfactory attractants used by honey bee swarms, in order of highest to lowest: Nasonov pheromone, comb odor, noncomb and propolis odors, and, finally, absence of bee- or hive-produced odor.

Sampling was conducted during June-October in 1997 and 1998 using drift fences with pitfall and funnel traps. Basal area of live trees, shade, leaf litter coverage, and litter depth was highest in controls and lowest in salvaged gaps. Percent cover, length, and diameter of coarse woody debris (CWD) were significantly greater in intact gaps than in salvaged gaps or controls. Coarse woody debris was more decayed and had less bark in controls than gaps. The relative abundance of salamanders and American toads, and species richness and diversity of amphibians did not differ among treatments. In contrast, relative abundance of two lizard species and (marginally) snakes, and species richness and diversity of reptiles was higher in both gap treatments than in controls. Results suggest that higher light in gaps positively influenced reptile abundance, but CWD at the tested levels was not an important determinant of habitat quality. The presence of a partial canopy and other forest features in both gap treatments may have adequately retained the microclimatic conditions required by moisture-sensitive amphibians. Xeric study sites and an associated assemblage of species that are pre-adapted to relatively warm, dry conditions also might partially explain the absence of any significant response by amphibians. In the closed canopy forests of the southern Appalachians, I suggest that salamanders were historically dominant, whereas many reptile species occurred at low densities and depended upon infrequent natural disturbance to create ephemeral patches of suitable habitat. Further study is required to determine what parameters of disturbance influence reptile and amphibian communities, and how these effects might differ along a moisture gradient and among species.

The Cry1C-resistant strain, which was derived from a field population that had evolved resistance to B. thuringiensis subsp. kurstaki and B. thuringiensis subsp. aizawai, was selected repeatedly with Cry1C in the laboratory. The Cry1C-resistant strain had strong cross-resistance to Cry1Ab, Cry1Ac, and Cry1F, low to moderate cross-resistance to Cry1Aa and Cry9Ca, and no cross-resistance to Cry1Bb, Cry1Ja, and Cry2A. Resistance to Cry1C declined when selection was relaxed. Together with previously reported data, the new data on the cross-resistance of a Cry1C-resistant strain reported here suggest that resistance to Cry1A and Cry1C toxins confers little or no cross-resistance to Cry1Bb, Cry2Aa, or Cry9Ca. Therefore, these toxins might be useful in rotations or combinations with Cry1A and Cry1C toxins. Cry9Ca was much more potent than Cry1Bb or Cry2Aa and thus might be especially useful against diamondback moth.

Saccharothrix cryophilis NRRL B-16238(T) appeared to be phylogenetically closest to Streptoalloteichus, but is morphologically distinct from this genus because sporangia with motile spores are not observed. The aerial mycelium fragments into rod-shaped elements and sclerotium-like bodies are observed occasionally in the substrate mycelium. The cell wall contains meso-diaminopimelic acid, whole-cell hydrolysates contain galactose, rhamnose and ribose, the phospholipid pattern is type PIV and the principal menaquinone is MK-9(H(4)). A new genus to accommodate Saccharothrix cryophilis is proposed, Crossiella gen. nov., in recognition of the contributions of Thomas Cross, a distinguished actinomycete biologist at the University of Bradford, UK. The type species is Crossiella cryophila gen. nov., comb. nov.

A corollary of this hypothesis is that per capita mating success of males increases with increasing lek size. Few field studies have tested this prediction via experimental manipulation of lek size. Here, I describe field studies that monitored female visits to artificially created leks of varying size in two species of tephritid fruit flies, the Mediterranean fruit fly, Ceratitis capitata, and the Oriental fruit fly, Bactrocera dorsalis. No support for the female preference hypothesis was detected for B. dorsalis. However, in C. capitata, mean ratios of female sightings:signalling males were significantly greater for leks containing 18 or 36 males than leks that contained only six males. The observation that C. capitata males in natural populations typically form small leks suggests that a female-male conflict exists regarding optimal lek size.

Following each of the enrichment techniques, samples were subcultured onto modified semisolid Rappaport-Vassiliadis (MSRV) agar prior to transfer to Hektoen Enteric agar plates for the recovery of viable Salmonella bacteria. Presumptive Salmonella isolates were biochemically and serologically confirmed. For the PCR detection of Salmonella, a 1-ml portion was removed from each sample after the first overnight enrichment and the DNA was extracted using a Sepharose CL-6B spin column. Amplicons (457 bp) derived from primers to the invA and invE genes were confirmed as Salmonella specific on ethidium bromide-stained agarose gels by Southern hybridization with a 20-mer oligonucleotide probe specific for the Salmonella invA gene. Neither the standard microbiological method nor the molecular method detected all of the 65 samples that tested positive by both methods or either method alone. Salmonella bacteria were detected by both cultivation and PCR-hybridization in 68% (17 of 25) of the positive samples that were preenriched in TSB, in 73% (11 of 15) of the positive samples preenriched in 3MC broth, and in 24% (6 of 25) of the positive samples enriched in RV10. Agreement between Salmonella detection using cultivation with preenrichment and detection by PCR was 76% using the kappa statistic. However, agreement between Salmonella detection using cultivation without preenrichment and detection by PCR was about 6%; the PCR assay detected 80% (20 of 25) of the 25 positive samples, while Salmonella bacteria were recovered from only 44% (11 of 25) by cultivation. Our results indicate that the PCR-hybridization approach is equivalent to or better than cultivation for detecting Salmonella in swine feces or water samples from swine farms when using the medium combinations evaluated in this study.

Regardless of glucosinolate content, seed meal amendment at a rate of 0.1% (vol/vol) significantly enhanced growth of apple and suppressed apple root infection by Rhizoctonia spp. and Pratylenchus penetrans. High glucosinolate B. napus cv. Dwarf Essex seed meal amendments did not consistently suppress soil populations of Pythium spp. or apple root infection by this pathogen. Application of a low glucosinolate containing B. napus seed meal at a rate of 1.0% (vol/vol) resulted in a significant increase in recovery of Pythium spp. from apple roots, and a corresponding reduction in apple seedling root biomass. When applied at lower rates, B. napus seed meal amendments enhanced populations of fluorescent Pseudomonas spp., but these bacteria were not recovered from soils amended with seed meal at a rate of 2% (vol/vol). Seed meal amendments resulted in increased soil populations of total bacteria and actinomycetes. B. napus cv. Dwarf Essex seed meal amendments were phytotoxic to apple when applied at a rate of 2% (vol/vol), and phytotoxicity was not diminished when planting was delayed for as long as 12 weeks after application. These findings suggest that B. napus seed meal amendments can be a useful tool in the management of apple replant disease and, in the case of Rhizoctonia spp., that disease control operates through mechanisms other than production of glucosinolate hydrolysis products.

A 1.85 kbp fragment of the rRNA operon from flavescence doree (FD) phytoplasma strain FD70 from France was amplified and cloned, and its nucleotide sequence determined (GenBank acc. no. AF176319). Placement of FD70 in subgroup V-C was verified by analysis of amplified DNA and of the cloned sequence. Hemp dogbane phytoplasma HD1 (AF122912), a member of subgroup V-C, was distinguished from other subgroup V-C phytoplasmas by putative restriction site differences in the 16S-23S rRNA spacer region. A previously published FD phytoplasma sequence (GenBank accession no. X76560) differed from FD70 sequence AF176319 by at least eight nucleotide substitutions and differences in putative restriction sites. The X76560 FD phytoplasma was classified in a new subgroup (V-D). Based on analyses of 16S rDNA GenBank sequence Y16395, Rubus stunt phytoplasma was classified in new subgroup V-E. The revised classification was supported by sequence similarities, group 16SrV-characteristic sequences, and a phylogenetic tree constructed on the basis of 16S rDNA sequences.

The field site was naturally infested with all three organisms. Peanut (P) was rotated with 2 years of either cotton (Ct), corn (C), or bahiagrass (B). The pesticide treatments for the peanut crop were aldicarb (31 g a.i. per 100-m row), flutolanil (1.7 kg a.i./ha), aldicarb + flutolanil, and a control without either pesticide. Populations of M. arenaria were lower in peanut in the Ct-Ct-P than in P-P-P, C-C-P, or B-B-P plots and tended to be lower in plots treated with aldicarb. Abundance of P. penetrans endospores was highest in the P-P-P plots, intermediate in the B-B-P rotations, lowest in all other rotations, and was unaffected by aldicarb. The high endospore densities in the P-P-P plots may have contributed to the uncharacteristically low nematode populations in the monoculture. Incidence of stem rot in peanut was lowest in treatments with flutolanil, intermediate in the control, and highest in treatments with aldicarb alone.

Considering that some of the same leaf spot pathogens found on grasses can cause diseases on wheat, the management practices used to convert these lands were evaluated for their effect on winter wheat leaf spot diseases. In a 3-year spring wheat-winter wheat-pea crop rotation, the major leaf spot diseases on winter wheat were tan spot and Stagonospora nodorum blotch. Removal of hay or leaving hay in the plots when converting grassland to cropland had no significant effect on leaf spot diseases, indicating that the residue from the grass-alfalfa crop did not influence leaf spot diseases on winter wheat. Tillage treatments did not influence the amount of disease in 1996, but with higher precipitation levels in 1999, higher disease severities were associated with the no tillage treatment. Higher levels of crop residue associated with the no tillage treatment could potentially carry over plant pathogens from one crop to the next. The severity of leaf spot diseases was consistently lower when nitrogen was applied, indicating the importance of nitrogen application when converting grassland to cropland.

Fusarium verticillioides (= F. moniliforme) is highly tolerant to MBOA and BOA and can actively transform these compounds to nontoxic metabolites. Eleven of 29 Fusarium species had some level of tolerance to MBOA and BOA; the most tolerant, in decreasing order, were F. verticillioides, F. subglutinans, F. cerealis (= F. crookwellense), and F. graminearum. The difference in tolerance among species was due to their ability to detoxify the antimicrobials. The limited number of species having tolerance suggested the potential utility of these compounds as biologically active agents for inclusion within a semiselective isolation medium. By replacing the pentachloronitrobenzene in Nash-Snyder medium with 1.0 mg of BOA per ml, we developed a medium that resulted in superior frequencies of isolation of F. verticillioides from corn while effectively suppressing competing fungi. Since the BOA medium provided consistent, quantitative results with reduced in vitro and taxonomic efforts, it should prove useful for surveys of F. verticillioides infection in field samples.

Most members of this community participated in mixed-species flocks. Seventy-three flocks were encountered during our study, containing 52 species. Of these, 25 species occurred in more than 10% of flocks, and were included in our analyses. There were 26 significant correlations among species pairs, 25 of which were positive. Cluster analysis indicated that there were three principal types of flocks: one consisting mostly of small passerines and picids, commonly including Common Wood-Shrike, Small Minivet and White-browed Fantail, among others; a second type consisting mainly of sylviids, e.g. Arctic, Dusky and Radde's Warblers; and a third type which generally centred around Greater and Lesser Necklaced Laughingthrushes. Bird-eating hawks were numerous at these sites, and we witnessed several attacks on flocks during the study. Thus we infer that enhanced protection from predation is an important benefit conferred by flock membership. In contrast, there was little overlap in foraging behaviour among species, suggesting that foraging facilitation is a relatively minor benefit enjoyed by flock members, although we did observe White-browed Fantails and Greater Racket-tailed Drongos kleptoparasitizing other species on occasion.

I estimated prairie skink density from a trapping grid using a mark-recapture method in seven old fields. For each field I estimated arthropod density, percent plant cover and recorded field age and if the field had been burned in the last 5 y. Arthropod density was highly variable among years and fields. Percent plant cover did not explain this variation, as it varied little among fields and years. Prairie skink density ranged from 58-206 adults per ha among fields and was significantly correlated with field age, arthropod abundance and burn treatment. Because of the small number of replicated sampling units, however, I was unable to determine the independent effects of each factor. Prairie skink density increased with successional age but the mechanisms responsible for this pattern remain unclear.

Isolated from Swine Feces AN - 17893318; 5130122 AB - Anaerobic bacteria resistant to the macrolide antibiotics tylosin and erythromycin were isolated from the feces of swine. One of the strains, 121B, was initially identified by 16S rDNA sequence analysis as an unknown Lactobacillus sp. The strain was found to contain at least two plasmids, one of which was capable of replicating and providing erythromycin and tylosin resistance to Bacillus subtilis, Streptococcus gordonii, and Escherichia coli. DNA sequence analyses of the 4,232-bp plasmid, p121BS, identified one open reading frame encoding a methylase gene highly similar (98% amino acid identity, 99% DNA sequence identity) to the ermT gene from the Lactobacillus reuteri plasmid pGT633. This is only the second ermT gene to be reported. p121BS also contains two additional open reading frames with significant amino acid similarities to replication proteins from Lactobacillus and other Gram-positive bacteria.

Poplar BSPs are encoded by a multigene family and one member, bspA, has been cloned and sequenced. The regulation of bspA was investigated by transforming either hybrid poplar or tobacco with a chimeric gene consisting of the 2.8 kb bspA promoter fused to the coding region of beta -glucuronidase (uidA). In transformed poplar, the bspA 2.8 kb promoter conferred both short-day (SD) and nitrogen (N) inducibility to GUS and activity was localized to the bark (primary and secondary phloem, and cortex) and xylem rays. Night-break treatments inhibited SD induction of GUS. Deletion of the 1.6 kb distal DNA sequences from the bspA promoter eliminated SD induction of GUS while some N induction was retained. These results indicate that although poplar BSP is encoded by a multigene family, transcriptional activation of bspA per se can account for bsp expression in bark and xylem rays in response to either SD or N treatment. These results also show that the elements responsible for SD or N induction are separable. Because of the long generation intervals associated with trees, the developmental regulation of bspA in flowers, developing seeds, and germinating seeds was investigated by transforming the 2.8 kb bspA-promoter::uidA chimeric gene into tobacco. The bspA promoter was active in developing tobacco floral tissues and in seeds during early stages of embryogenesis, decreased progressively during seed maturation and regained activity upon seed germination. Although seed storage proteins of poplar share some similarities to poplar BSP, the observed developmental expression patterns in tobacco are consistent with a role for bspA in vegetative rather than seed storage protein storage.

This study was designed to analyze the effects of salinity on plant growth and yield components of rice by composing 20-day periods of salinization at different growth stages. Plants were grown in sand tanks in a greenhouse and irrigated with nutrient solutions. Treatments were three levels of salinity with electrical conductivities at 1.8, 3.2 and 4.6 dS m super(-1) and five timing treatments. Plants were salinized on the day of seeding, 1-leaf, 3-leaf, panicle initiation (PI), and booting stages, respectively, and stress was relieved after 20 days in each timing treatment. Salinity-induced reductions in shoot dry weights of plants harvested before PI were significant, but there were no significant differences among timing treatments. Reduction in shoot dry weight of plants harvested at seed maturity was significant only when plants were salinized for a 20-day duration before booting, but not after booting. Reduction in tiller number per plant was significant only when plants were salinized for a 20-day duration before PI. The reductions in spikelets per panicle and seed weight per panicle were most pronounced when plants were stressed between the 3-leaf and PI stages or between PI and booting stages and minor when stressed at the other stages. A 20-day period between 3-leaf and PI stages was most sensitive to salinity in terms of seed yield. These results indicate that the differential sensitivity at growth stages can be clearly shown when stages are well defined in the timing treatments and the stress is quantified at growth stages based on the same duration of salinization. The interaction between cultivar and timing treatment was not significant. Uniform management options can be developed for irrigation using saline water for the cultivars with similar genetic backgrounds.

D4E1 inhibited the growth of several fungal phytopathogens belonging to four classes - Ascomycetes, Basidiomycetes, Deuteromycetes, and Oomycetes, and two bacterial pathogens, Pseudomonas syringae pv. tabaci and Xanthomonas campestris pv. malvacearum race 18. The minimum inhibitory concentration (MIC) of D4E1 required to completely inhibit the growth of all fungi studied ranged from 4.67 to 25 mu M. Fungal pathogens highly sensitive to D4E1 include Thielaviopsis basicola, Verticillium dahliae, Fusarium moniliforme, Phytophthora cinnamomi, and Phytophthora parasitica. Comparatively, the least sensitive fungal pathogens were Alternaria alternata, Colletotrichum destructivum, and Rhizoctonia solani. The two bacterial pathogens, P. syringae pv. tabaci and X. campestris pv. malvacearum race 18, were most sensitive to D4E1 with MIC values of 2.25 and 1.25 mu M, respectively. Microscopic analysis of D4E1 effects on fungal morphology of Aspergillus flavus and R. solani revealed abnormal hyphal growth and discontinuous cytoplasm. After 8 h of exposure to 25 mu M D4E1, A. flavus spore germination was reduced by 75%. The suitability of peptide D4E1 to enhance disease resistance in transgenic crop plants is discussed.

AN - 70949430; 11417873 AB - Immunoaffinity chromatography (IAC) for the purification of polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) from biological samples was explored as a means to simplify the cleanup procedure and thereby decrease the time and cost of dioxin analysis. A monoclonal antibody (DD3) was used to produce IAC columns and to isolate the PCDD/Fs from serum. Native and 13C-labeled PCDD/Fs were spiked at the ppq to ppt range into serum. Quantitation of the PCDD/Fs was performed by a standard dioxin analytical method, i.e. high-resolution gas chromatography-mass spectrometry (GC-MS), which was easily compatible with IAC. Five of the most toxic PCDD/Fs consistently showed acceptable recoveries (>25%) and were reliably quantitated. The congeners specifically recovered by this method represent almost 80% of the toxic equivalency of dioxins and furans present in the serum samples. Dioxin-like polychlorinated biphenyls (PCBs) were not recognized by this antibody column. Compared to conventional dioxin cleanup methods, IAC decreased solvent usage by 1.5 l/sample and took only 2 h to process a sample for analysis. JF - Journal of chromatography.

However, Borrelia burgdorferi, the causative agent of Lyme disease, has not been cultured from skin biopsy specimens from these patients, and diagnostic serum antibodies usually have not been found. Borrelia lonestari sp nov, an uncultured spirochete, has been detected in A. americanum ticks by DNA amplification techniques, but its role in human illness is unknown. We observed erythema migrans in a patient with an attached A. americanum tick. DNA amplification of the flagellin gene flaB produced B. lonestari sequences from the skin of the patient that were identical to those found in the attached tick. B. lonestari is a probable cause of erythema migrans in humans.

Brant). Seedlings were grown in chambers under ambient (36 Pa) and elevated (100 Pa) carbon dioxide and were fertilized daily with complete nutrient solution providing 12 millimolar nitrate and 2.5 millimolar ammonium. Foliar nitrate and ammonium were 27% and 42% lower (P , 0.01) in the elevated compared to ambient carbon dioxide treatments, respectively. Enhanced carbon dioxide affected leaf ammonium levels by inhibiting photorespiration. Diurnal variations of total nitrate were not observed in either treatment. Total and Mg super(2+)inhibited nitrate reductase activities per gram fresh weight were slightly lower (P , 0.01) in enhanced compared to ambient carbon dioxide between 8 and 15 DAS. Diurnal variations of total nitrate reductase activity in barley primary leaves were similar in either treatment except between 7 and 10 h of the photoperiod when enzyme activities were decreased (P , 0.05) by carbon dioxide enrichment. Glutamate was similar and glutamine levels were increased by carbon dioxide enrichment between 8 and 13 DAS. However, both glutamate and glutamine were negatively impacted by elevated carbon dioxide when leaf yellowing was observed 15 and 17 DAS. The above findings showed that carbon dioxide enrichment produced only slight modifications in leaf nitrogen metabolism and that the chlorosis of barley primary leaves observed under enhanced carbon dioxide was probably not attributable to a nutritionally induced nitrogen limitation.

The effects of the presence of alcohol and of the amount of enzyme used were studied. The matrix-immobilized PS-30 lipase effectively converted grease and tallow to ethyl esters in greater than 95% yield when using ethanol. The final conversion of grease or tallow to alkyl esters was aided by the addition of molecular sieves (0.4 wt% of substrates) to the reaction mixture. The matrix-immobilized PS-30 enzyme was easily recovered and could be reused at least five times without losing its activity.

AN - 71003543; 11444416 AB - To determine the effects of combined zinc (Zn) and chromium (Cr) supplementation on oxidative stress and glucose homeostasis of people with type 2 diabetes. Tunisian adult subjects with HbA1C > 7.5% were supplemented for 6 months with 30 mg/d of Zn as Zn gluconate or 400 microg/d of Cr as Cr pidolate or combined Zn/Cr supplementation or placebo. The effects of supplementation on plasma zinc (Zn), copper (Cu), selenium (Se), urinary Zn, Cr, plasma thiobarbituric acid reactive substances (TBARS), Cu-Zn superoxide dismutase (SOD) and Se glutathione peroxidase (GPx) in red blood cells, blood lipids and lipoproteins, HbA1C and fasting glucose were measured at the beginning of the study and after six months. At the beginning of the study, more than 30% of the subjects may have been Zn deficient with plasma Zn values less than 10.7 mircomol/L, whereas levels of plasma Cu, Se and antioxidant RBC enzyme activities were in the normal ranges. Following supplementation, there were significant decreases of plasma TBARS in the Cr (13.6%), Zn (13.6%) and Zn/Cr (18.2%) groups with no significant changes in the placebo group. The value for the TBARS of the control healthy Tunisian subjects was 2.08 +/- 0.04 micromol/L and that of the Tunisian subjects with diabetes was 3.32 +/- 0.05 micromol/L. This difference of 1.24 micromol/L between the control group and the subjects with diabetes was reduced from 36% to 50% in the three supplemented groups. Supplementation did not modify significantly HbAIC nor glucose homeostasis. No adverse effects of Zn supplementation were observed on Cu status. HDL cholesterol nor interactions in Zn or Cr. These data suggest the potential beneficial antioxidant effects of the individual and combined supplementation of Zn and Cr in people with type 2 DM. These results are particularly important in light of the deleterious consequences of oxidative stress in people with diabetes.

AN - 70976966; 11434545 AB - Three experimental approaches were used to evaluate the oviposition deterrency of three insect repellents, AI3-35765, AI3-37220 (piperidine compounds), and the standard N,N-diethyl-3-methylbenzamide (deet) to the mosquito Aedes albopictus Skuse (Diptera: Culicidae). Against laboratory-reared Ae. albopictus gravid females, the EC50 values of AI3-37220, AI3-35765 and deet were 0.004%, 0.008% and 0.011% in laboratory cages and 0.004%, 0.01% and 0.009% in an outdoor screened cage. For a natural population of Ae. albopictus tested in the field, the EC50 values were determined as 0.004%, 0.008% and 0.001%, respectively. Ageing concentrations of 0.1% of each repellent provided >50% effective oviposition deterrency against the laboratory population of Ae. albopictus for 13 days in laboratory cages, for 15 days in the outdoor cage, and for 21 days against field population of Ae. albopictus in Florida. These topical skin repellents are effective oviposition deterrents for Ae. albopictus when employed at relatively low application rates.

AN - 70959936; 11410018 AB - The fate of fumonisin B(1) (FB(1)), a mycotoxin found in corn, during the commercial manufacture of fried tortilla chips was studied. FB(1) and hydrolyzed FB(1) (HFB(1)) concentrations in four lots of corn and in the masa, other intermediates, liquid and waste byproducts, and fried chips were determined by HPLC. FB(1) concentrations in the masa and chips were reduced significantly, up to 80% in the fried chips, compared to that in the raw corn. HFB(1) was also found in the masa and chips, but at low concentrations compared to FB(1). LC-MS analyses corroborated HPLC findings and further showed the presence of partially hydrolyzed FB(1) (PHFB(1)), which, like HFB(1), was formed during the nixtamalization (cooking/steeping the corn in alkaline water to make masa) step and found predominantly in the cooking/steeping liquid and solid waste. No significant amounts of N-(carboxymethyl)-FB(1) or N-(1-deoxy-D-fructos-1-yl)-FB(1), indicative of fumonisin-sugar adduct formation, were found. Thus, FB(1) is removed from corn and diverted into liquid and waste byproducts during the commercial production of fried tortilla chips. Nixtamalization and rinsing are the critical steps, whereas grinding, sheeting, baking, and frying the masa had little effect.

AN - 70955174; 11425027 AB - The acetylcholinesterase, carboxylesterase, and cytochrome P450 monooxygenase activities of three strains of Oryzaephilus srinamensis (L.) were examined to better understand biochemical mechanisms of resistance. The three strains were VOS49 and VOSCM, selected for resistance to malathion and chlorpyrifos-methyl, respectively, and VOS48, a standard susceptible strain. Cross-resistance to malathion and chlorpyrifos-methyl was confirmed in VOS49 and VOSCM. Acetylcholinesterase activity was not correlated to resistance among these strains. VOS49 and VOSCM showed elevated levels of carboxylesterase activity based on p-nitrophenylacetate, alpha-naphthyl acetate, or beta-naphthyl acetate substrates. PAGE zymograms showed major differences in caboxylesterase isozyme banding among strains. VOSCM had one strongly staining isozyme band. A band having the same Rf-value was very faint in VOS48. The VOS49 carboxylesterase banding pattern was different from both VOSCM and VOS48. Cytochrome P450 monooxygenase activity was based on cytochrome P450 content, aldrin epoxidase activity, and oxidation of organophosphate insecticides, all elevated in resistant strains. The monooxygenase activity varied with insecticide substrate and resistant strain, suggesting specific cytochromes P450 may exist for different insecticides. The monooxygenase activity of the VOS49 strain was much higher with malathion than chlorpyrifos-methyl as substrates, whereas VOSCM monooxygenase activity was higher with malathion than chlorpyrifos-methyl as substrates. Results are discussed in the context of resistance mechanisms to organophosphate insecticides in O. surinamensis.

AN - 70917930; 11407032 AB - The fumigant toxicity of various volatile constituents of essential oils extracted from sixteen Korean spices and medicinal plants towards the rice weevil, Sitophilus oryzae L (Coleoptera: Curculionidae), was determined. The most potent toxicity was found in the essential oil from Mentha arvensis L. var piperascens (LC50 = 45.5 microliters litre-1 air). GC-MS analysis of essential oil from M arvensis showed it to be rich in menthol (63.2%), menthone (13.1%) and limonene (1.5%), followed in abundance by beta-pinene (0.7%), alpha-pinene (0.6%) and linalool (0.2%). Treatment of S oryzae with each of these terpenes showed menthone to be most active (LC50 = 12.7 microliters litre-1 air) followed by linalool (LC50 = 39.2 microliters litre-1 air) and alpha-pinene (LC50 = 54.9 microliters litre-1 air). Studies on inhibition of acetylcholinesterase activity of S oryzae showed menthone to have a nine-fold lower inhibitory effect than menthol, despite menthone being 8.1-fold more toxic than menthol to the rice weevil. Different modes of toxicity of these monoterpenes towards S oryzae are discussed.

AN - 70917277; 11403141 AB - Food substrate chemistry is known to influence radiation sensitivity of pathogenic bacteria. The sensitivity of a citrus juice outbreak strain of Salmonella Enteritidis to gamma radiation was determined in five commercial orange juice formulations. The juices differed in pH (3.87 to 4.13), calcium concentration (2.1 versus 36.9 mM), juice composition (orange versus orange-tangerine blend), and antioxidant power (11,751 to 12,826 microM ferric reducing-antioxidant power units). The Dgamma (dose required to achieve 90% destruction) varied only slightly (0.35 to 0.37 kGy), with no significant (P < 0.05) differences among any of the suspending juices. These results indicate that Salmonella Enteritidis sensitivity to gamma radiation is not strongly influenced by the composition of formulated commercial orange juices.

AN - 70915520; 11409960 AB - A gas chromatographic method for the analysis of 10 organochlorine pesticides in 0.5 mL of whole blood is described. Sample preparation involved an ethyl ether and hexane extraction, followed by a silica solid phase extraction cleanup. The pesticides are quantified by gas chromatography/electron capture detection. Method limits of detection ranged from 1.1 to 5.2 microg/L. The mean and standard deviation for the recovery of 10 pesticides was 97.9 +/- 5.5%. Recoveries from whole blood were comparable to recoveries from plasma. This indicates that the preparation of plasma is unnecessary for the quantification of organochlorine pesticides in blood.

AN - 70905445; 11402197 AB - Pollen hydration is usually tightly regulated and occurs in vivo only when desiccated pollen grains acquire water from the female, thus enabling pollen tube growth. Pollen tubes are easily visualized by staining with decolorized aniline blue, a stain specific for callose. We identified a mutant, raring-to-go, in which pollen grains stained for callose before anther dehiscence. When raring-to-go plants are transferred to high humidity, pollen tubes dramatically elongate within the anther. As early as the bicellular stage, affected pollen grains in raring-to-go plants acquire or retain water within the anther, and precociously germinate. Thus, the requirement for contact with the female is circumvented. We used pollen tetrad analysis to show that raring-to-go is a gametophytic mutation, to our knowledge the first gametophytic mutation in Arabidopsis that affects early events in the pollination pathway. To aid in identifying raring-to-go alleles, we devised a new technique for screening pollen in bulk with decolorized aniline blue. We screened a new M(1) mutagenized population and identified several additional mutants with a raring-to-go-like phenotype, demonstrating the usefulness of this technique. Further, we isolated other mutants (gift-wrapped pollen, polka dot pollen, and emotionally fragile pollen) with unexpected patterns of callose staining. We suggest that raring-to-go and these other mutants may help dissect components of the pathway that regulates pollen hydration and pollen tube growth.

Thus, there is a need for small in-field runoff collectors to assess nutrient migration at the field scale on various land management systems. A runoff sampler previously designed for the relatively flat terrain of the Coastal Plain was modified to accommodate steeper slopes (5% to 12%), larger flow rates, and channelized flow common in the Southern Piedmont. We conducted a laboratory study with the modified sampler to evaluate the effect of flow rate (1 to 5.5 L min super(-1)) and slope (5% and 12%) on percent flow capture. Our results show that slope and flow rate had little to no effect on the percent flow capture of the modified runoff collector. The 95% confidence interval for percent flow capture in a single observation was 10.4 plus or minus 2.5% for the 10x splitter and 2.0 plus or minus 1.7% for the 100x splitter. Because of the potential errors for single observations, several runoff collectors should be used if runoff volume needs to be quantified. The use of this small in-field runoff collector would be fairly unobtrusive, inexpensive in different management systems, and could help further our knowledge of migration of nutrients, pesticides, microorganisms, and sediments from fields into streams.

For this study, 34 newly established cell lines from 10 lepidopteran species were screened for their ability to produce ECV and OBs from a variety of baculoviruses. The selected baculoviruses included: the alfalfa looper virus (AcMNPV); the celery looper virus (AfMNPV); the velvetbean caterpillar virus (AgMNPV), the bollworm virus (HzSNPV), the diamondback moth virus (PxMNPV), and the beet armyworm virus (SeMNPV). ECV titers were determined using TCID50 assays (50% tissue culture infectivity dose), with the presence or absence of OBs being noted. For AcMNPV, 28 new cell lines were tested, with eight producing AcMNPV ECV titers of 1.1-47.3 106 TCID50/ml and 11 producing OBs. For AgMNPV, six new cell lines were tested, with all producing AgMNPV ECV titers of 3.5-62.3 106 TCID50/ml and generating OBs. For HzSNPV, four new cell lines were tested with three lines producing HzSNPV ECV titers of 1.4-5.0 106 TCID50/ml, but none generating OBs. For PxMNPV, 10 new cell lines were tested with seven generating PxMNPV ECV titers of 4.7-232.6 106 TCID50/ml and eight producing OBs. Lastly, using qualitative or semiquantitative methods, homologous cell lines were tested for AfMNPV and SeMNPV production, all of which produced OBs. Overall, many of the cell lines tested were found to produce OBs and generate moderate to high levels of ECVs of one or more baculoviruses.

However, during starvation, the midgut shrinks and the rate of cell replacement appears to be suppressed. When they undergo metamorphosis, the internal organs of insects are drastically remodeled by cell proliferation, differentiation, and apoptotic processes, and the net number of cells usually increases. An extract of 1650 midguts of Periplaneta americana was fractionated by high-performance liquid chromatography (HPLC) to obtain the peptides that regulate these processes. The HPLC fractions were tested for myotropic activity in the foregut and for effects on cell proliferation or loss in primary cultures of larval Heliothis virescens midgut cells and in a cell line derived from the last-instar larval fat body of Mamestra brassicae. Some fractions stimulated midgut stem cell proliferation and differentiation, while others caused loss of differentiated columnar and goblet cells. Other fractions stimulated cell proliferation in the larval fat body cells.

A total of 36 new cell lines from 10 lepidopteran species were generated, including cell lines from a pyralid, the European corn borer, Ostrinia nubilalis, a plutellid, the diamondback moth, Plutella xylostella, as well as eight noctuids: the black cutworm, Agrotis ipsilon, the celery looper, Anagrapha falcifera, the velvetbean caterpillar, Anticarsia gemmatalis, the corn earworm, Helicoverpa zea, the tobacco budworm, Heliothis virescens, the beet armyworm, Spodoptera exigua, the fall armyworm, Spodoptera frugiperda, and the cabbage looper, Trichoplusia ni. Tissues used for cell line establishment included fat bodies, ovaries, testes, or whole embryos/larvae/pupae. All the cell lines were subcultured numerous times, characterized by isoenzyme analysis and/or deoxyribonucleic acid amplification fingerprinting using polymerase chain reaction, and stored in liquid nitrogen. Many of the cell lines were adapted to grow in serum-free medium, with cell lines from A. ipsilon and H. virescens being adapted to suspension culture using shaker flasks. The potential use for these cell lines in baculovirus production is discussed.

Sixteen older women with CHF were compared with 80 age-matched peers without CHF and randomized to progressive resistance training or control stretching exercises for 10 wk. Women with CHF had significantly lower muscle strength (P < 0.0001) but comparable aerobic capacity to women without CHF. Exercise training was well tolerated and resulted in no changes in resting cardiac indexes in CHF patients. Strength improved by an average of 43.4 plus or minus 8.8% in resistance trainers vs. _1.7 plus or minus 2.8% in controls (P = 0.001), muscle endurance by 299 plus or minus 66% vs. 1 plus or minus 3% (P = 0.001), and 6-min walk distance by 49 plus or minus 14 m (13%) vs. _3 plus or minus 19 m (_3%) (P = 0.03). Increases in type I fiber area (9.5 plus or minus 16%) and citrate synthase activity (35 plus or minus 21%) in skeletal muscle were independently predictive of improved 6-min walk distance (r super(2) = 0.78; P = 0.0024). High-intensity progressive resistance training improves impaired skeletal muscle characteristics and overall exercise performance in older women with CHF. These gains are largely explained by skeletal muscle and not resting cardiac adaptations.

Techniques for establishing bottomland tree species are well developed, yet problems have occurred in operational programs. Current plans for restoration on public and private land suggest that as many as 200,000 hectares could be restored in the Lower Mississippi Alluvial Valley alone. The ideal of ecological restoration is to reestablish a completely functioning ecosystem. Although some argue that afforestation is incomplete restoration, it is a necessary and costly first step but not an easy task. The 1992 Wetlands Reserve Program in Mississippi, which failed on 90% of the area, illustrates the difficulty of broadly applying our knowledge of afforestation. In our view, the focus for ecological restoration should be to restore functions, rather than specifying some ambiguous natural state based on reference stands or pre-settlement forest conditions. We view restoration as one element in a continuum model of sustainable forest management, allowing us to prescribe restoration goals that incorporate landowner objectives. Enforcing the discipline of explicit objectives, with restoration expectations described in terms of predicted values of functions, causal mechanisms and temporal response trajectories, will hasten the development of meaningful criteria for restoration success. We present our observations about current efforts to restore bottomland hardwoods as nine myths, or statements of dubious origin, and at best partial truth.

Muscle fibers must have a broad range of contractile velocities to generate the full range of power required for varied activities. Design: Percutaneous needle biopsies of the vastus lateralis were obtained from 31 healthy subjects (n = 7 young men [YM], n = 7 young women [YW], n = 12 older men [OM], n = 12 older women [OW]). The slack test was used to determine Vo of individual fibers; 916 muscle fibers were chemically skinned. Fiber type was determined by myosin heavy chain isoform identification. Results: Among men, Vo (fiber lengths/sec) was reduced with age in Type IIA fibers (OM vs. YM: 1.78 vs. 2.14; P < 0.05) but unchanged in Type I fibers. Among women, Vo was reduced with age in Type I fibers (OW vs. YW: 0.70 vs. 0.75; P < 0.05) but not IIA. OW had a lower Vo than did OM in both fiber types (Type I: OW = 0.70, OM = 0.77; Type IIA: OW = 1.51, OM = 1.78; P < 0.05). YW did not differ from YM. Conclusions: Both age and gender affect Vo. Age- and gender-related differences in Vo may partially explain the impairments in muscle function that occur with aging and the greater impairment in muscle function observed in OW compared with that observed in OM.

Cantaloupes were treated as follows: (i) water washed, or (ii) washed in solutions of sodium hypochlorite (1,000 mg/liter) or hydrogen peroxide (5%) for 5 min. Bioluminescence ATP assay results showed differences in ATP level/ cm super(2) of cantaloupes dipped in chlorine or hydrogen peroxide solution; ATP levels in these washed samples were lower than in controls due to antimicrobial action of the treatments on the cantaloupe surface. Linear correlations were found between the bioluminescence ATP assay and aerobic plate counts of unwashed cantaloupe (r super(2) = 0.995) and those washed with water (r super(2) = 0.990) determined before storage. Lower correlations between the bioluminescence ATP assay and the aerobic plate counts were observed on cantaloupes stored for 120 h at 20 degree C (r super(2) = 0.751) than at 4 degree C (r super(2) = 0.980) without washing treatment. Lower correlation at 20 degree C may be the result of clusters or growth that occurred in chains. ATP levels of washed cantaloupes correlated well with bacterial plate counts (r super(2) = 0.999). A reliable minimum detectable threshold using the bioluminescence ATP assay was established at 3 log sub(10) fg/cm super(2) corresponding to 4 log sub(10) CFU/cm super(2). Bioluminescence ATP assay is not recommended for washed samples where the microbial load is near or below the threshold. Therefore, the bioluminescence ATP assay will be recommended for quick estimation of total microbial load on cantaloupe surfaces where the population is expected to exceed this threshold. The assay can save the industry time by eliminating the required incubation required by the conventional methods.

Immunomagnetic beads or antibody-labeled streptavidin-coated magnetic beads were then used to capture the APase-tagged E. coli. Immunomagnetically captured bacteria were washed and distributed into microplates or optical cuvettes. The enzyme-catalyzed hydrolysis of p-nitro-phenol phosphate in alkaline solutions was then followed. Less than 1000 cfu/ml of E. coli O157:H7 could be detected.

The specific objectives of these experiments were to test the effects of different loading rates of anaerobically digested dairy manure on nitrogen removal efficiency and nitrification within algal turf scrubbers (ATS). Laboratory-scale ATS units were operated by continuously recycling 220 l of wastewater and adding manure effluents daily. The algal turfs contained mixed indigenous assemblages of benthic algae. The most abundant genera were Ulothrix, Oedogonium, and Rhizoclonium. Weekly harvest of algal biomass, and wastewater samples were analysed for total Kjeldahl nitrogen (TKN), ammonium (NH sub(4)-N), nitrate, and elemental composition. In previous experiments with loading rates of 0.6-0.96 g TN m super(-2) d super(-1), algal nitrogen accounted for 42-50 % of input NH sub(4)-N. Nitrate production accounted for the bulk of remaining input NH sub(4)-N. Lower loading rates (0.24 and 0.48 g TN m super(-2) d super(-1)) tested here showed a higher removal rate where algal nitrogen accounted for 71% of input NH sub(4)-N (56% of TN), and nitrate production was negligible. The disappearance of NH sub(4)-N from wastewater in scrubbers measured over 4-5 hours showed initial rates of about 6 mg NH sub(4)-N hr super(-1) g super(-1) DW algae, corresponding to 3.7 g NH sub(4)-N d super(-1) m super(-2). This was followed by slightly lower rates, probably indicating limitation in carbon and/or micronutrients.

An alternative to land spreading is to grow crops of algae on the N and P present in the manure. The general goals of our research are to assess one algal production technology, termed algal turf scrubbers (ATS) to recover nutrients from animal manures. The specific objectives of these experiments were to test different loading rates of anaerobically digested dairy manure on nitrogen removal rates. Algal turfs were grown in a laboratory-scale ATS unit (1 m super(2)) operated by recycling wastewater and adding manure effluents daily. The most abundant genera of benthic algae in the ATS unit were Ulothrix, Oedegonium and Rhizoclonium. Replicate subsamples (0.04 m super(2)) of algal turfs of the same age were removed from the ATS unit and treated with different loads of manure containing 5-40 mg l super(-1) ammonium-N (NH sub(4)-N). During the experiments, the pH was maintained between 7-7.5 to prevent ammonia volatilization. Ammonium-N removal rates were biphasic, with a fast rate of 3.0-4.7 mg-NH sub(4)-N hr super(-1)g super(-1) DW for the first 20-30 minutes, followed by a slower rate of 0.53-0.96 mg-NH sub(4)-N hr super(-1)g super(-1) DW for the remainder of the 2 hour incubation period. The initial rates are comparable to laboratory scale ATS units and correspond to calculated removal rates of about 3 g NH sub(4)-N m super(-2)d super(-1).

That apparently resulted from owls preying upon Deer Mice (Peromyscus maniculatus) which had incidentally consumed knapweed seeds while foraging for the larvae of biological control agents within knapweed seedheads. Successful germination of 1% of the seeds shows that knapweed seeds recovered from owl pellets can be viable after being ingested by both species and suggest that Great Horned Owls can act as indirect dispersers of Spotted Knapweed seeds.

However, relative density of Ascaphus in the warmest reach, immediately downstream of a lake outlet, was lower than in cooler reaches downstream. Although we observed larvae and frogs in water temperatures up to 21 degree C, cold groundwater seeps contributed to a spatially complex thermal structure in the warmest stream reach. Frogs congregating near a cold seep and nesting in a groundwater-influenced site were likely using behavioral thermoregulation. At a stream weir in the warmest reach, we captured 32 Tailed Frogs moving downstream and none upstream, in September and October 1997. Because no migration was evident at five other weirs where summer water temperatures remained below 16 degree C, we propose that the frogs moving through upper Moore Creek migrated seasonally to avoid the high temperatures. The mature frogs may spend summers in the small, cold lake inlet streams, moving downstream in the fall to overwinter. Behavioral studies would be necessary to determine the extent to which individuals limit their overall thermal exposure in such spatially complex environments. Migration in response to local, seasonally changing habitat suitability could explain the diverse, and apparently contradictory, movement patterns (or lack thereof) among Ascaphus populations reported in the literature. Future studies of Ascaphus movements could benefit by accounting for seasonal changes in habitat suitability and by quantifying in-stream movements.

Retention efficiency was measured using short-term nutrient and tracer injections to estimate nutrient uptake length (S sub(w)) during summer 1999 and winter 2000. A one-dimensional transport model was used to estimate dispersion, transient storage size, and exchange. Soluble reactive P (SRP) and NO sub(3)-N concentrations were least in the stream with the lowest proportion of pasture in the upland (Dry Creek), whereas concentrations and land use were similar in Cherokee Creek and Cloud Creek. Water column SRP concentrations were similar between seasons in all streams, but NO sub(3)-N concentrations varied significantly. Injected NO sub(3)-N was not significantly retained in these systems, probably because the streams were saturated by ambient NO sub(3)-N concentrations (greater than 0.1 mg L super(-1)). Phosphorus was retained during summer injections (S sub(w) ranged from 200-900 m), but S sub(w) regressions were not significant in winter. Variation in catchment land use was not a major determinant in P retention during summer, but stream hydrology, such as discharge and transient storage, was a regulating factor. Therefore, land use changes that alter stream hydrology may have a greater impact on P retention in these streams.

Three surfactants, one anionic (sodium dodecyl benzene sulfonate) and two cationic (polyoxyropylene methyl diethyl ammonium chloride and tetradecyl trimethyl ammonium bromide), were tested on a sandy loam. The best surfactants are those capable of substantially reducing the amount of leaching under saturated and unsaturated flow conditions. Maintaining acceptable mechanical compaction characteristics, and if possible, limiting nitrate mobility, are also important. The experimental program therefore focused on three areas: (1) Surfactant influence on leaching as indicated by effects on soil hydraulic properties (saturated hydraulic conductivity, soil moisture diffusivity, and unsaturated soil wetting front penetration); (2) Surfactant effects on mechanical compaction; and (3) Nitrate transport in surfactant-modified soil. Saturated hydraulic conductivity was measured using falling-head permeability, tests. Transient unsaturated horizontal column experiments provided information concerning surfactant influence on soil moisture diffusivity and wetting front penetration. Standard Proctor methods were applied in the study of surfactant effects on mechanical compaction. Adsorption batch tests gauged nitrate mobility in surfactant-treated soil. The anionic surfactant (sodium dodecyl benzene sulfonate) and one of the two cationic surfactants (polyoxypropylene methyl diethyl ammonium chloride) produced considerable reductions in saturated hydraulic conductivity, soil moisture diffusivity, and unsaturated soil wetting front penetration. With regard to mechanical compaction, the anionic sarfactant and the other cationic surfactant (tetradecyl trimethyl ammonium bromide) affected decreases in the optimum moisture content corresponding to maximum dry bulk density. The moisture content range between optimum and the wet value corresponding to 90% or 95% maximum dry bulk density is also much narrower for these two surfactants, thereby increasing the difficulty of field compaction. Interestingly, the cationic surfactant having the greatest influence on soil hydraulic properties was not the same one having the most substantial effect on mechanical compaction. Adsorption batch tests indicate nitrate mobility in the sandy loam is not significantly altered by soil treatment with any of the three surfactants. The polyoxypropylene methyl diethyl ammonium chloride test results (no adverse effects on mechanical compaction and reduced hydraulic conductivity, diffusivity, and wetting front penetration) are alone enough to suggest the feasibility of using surfactants to enhance soil performance for animal waste management. However, more investigation is needed with a greater variety of surfactants on a number of different soils, particularly with regard to hydraulic property testing using leachate typically generated at animal feedlot and dairy facilities.

To protect these water sources, management practices to reduce nutrient movement or accumulation are being evaluated using computer models. The computer models, Groundwater Loading Effects of Agricultural Management Systems (GLEAMS) and a version of Riparian Ecosystem Management Model (REMM), were used to estimate nitrogen and phosphorus transport of nutrients through a riparian buffer zone from an agricultural field that received swine lagoon effluent. The models simulated annual application rates of effluent equivalent to 500 and 1000 kg N/ha. The GLEAMS model provided the weather data and nutrient concentrations in the soil, sediment, and leachate for input into REMM. Assuming a 1000 kg N/ha loading rate, GLEAMS monthly average NO sub(3)-N leachate concentrations were within 14% of the observed data, and REMM-simulated NO sub(3)-N leachate concentration was within 5% of the observed data. Both models provided an adequate estimation of nitrogen transport through the system. GLEAMS simulations of PO sub(4)-P leachate followed the general trend of observed data. However, there was no apparent response in simulated PO sub(4)-P leachate concentrations for the two loading rates (95 and 190 kg P/ha), indicating a problem in the phosphorus calculations in the model. The REMM-simulated PO sub(4)-P leachate was greater than observed concentrations and was affected by the inputs obtained from GLEAMS. The pre-release version of REMM provided good estimates of the nutrient transport, and with a few improvements, official releases of REMM have the potential to provide better estimates of nutrient movement through the riparian buffer zone.

Because we were not able to document any genomic diversity in our collection of Xylella fastidiosa strains isolated from diseased citrus, the observed gradient of increasing disease severity from southern to northern regions of Sao Paulo State is unlikely due to the presence of significantly different strains of the pathogen in the different regions. When comparisons were made to reference strains of Xylella fastidiosa isolated from other hosts using these methods, four groups were consistently identified consistent with the hosts and regions from which the strains originated: citrus and coffee, grapevine and almond, mulberry, and elm, plum, and oak. Independent results from random amplified polymorphic DNA (RAPD) PCR assays were also consistent with these results; however, two of the primers tested in RAPD-PCR were able to distinguish the coffee and citrus strains. Sequence comparisons of a PCR product amplified from all strains of Xylella fastidiosa confirmed the presence of a CfoI polymorphism that can be used to distinguish the citrus strains from all others. The ability to distinguish Xylella fastidiosa strains from citrus and coffee with a PCR-based assay will be useful in epidemiological and etiological studies of this pathogen.

In this study, liquid culture-produced blastospores of the entomopathogenic fungus Paecilomyces fumosoroseus were formulated with different inert and organic materials prior to air-drying. Paecilomyces fumosoroseus blastospores were produced in two different liquid media, a basal salts medium supplemented with Casamino acids and glucose (LM1) and a medium containing peptone of collagen and glucose (LM2). Blastospores produced in the two test media were formulated with various supports. The formulation supports were cornstarch, rice flour, talc powders, Mexican lime, calcined kaolin clay, and diatomaceous earth. Several of the supports were tested at different concentrations. The initial and long-term (after storage at 4 and 28 degree C) survival of the formulated, air-dried blastospores were evaluated. Initial blastospore viabilities were affected by the formulation material and by the blastospore production medium. Medium composition, drying support and storage temperature had an impact on the long-term survival of the blastospores. Under the conditions of the study, LM1 produced higher concentrations of blastospores that not only survived drying better than blastospores produced in LM2 but also maintained viability longer during storage in the formulation supports tested. The nature of the drying supports was shown to have a significant impact on the storage stability of all blastospores, particularly those produced in LM1. Under the production, drying and storage conditions used in the study, calcined kaolin clay formulations stored at 4 degree C had the best storage stability. In all formulations tested, spore survival over time was reduced for blastospore formulations stored at 28 degree C rather than 4 degree C.

A total of 31,732 ants were collected from pitfall traps and 54,694 ants were collected from bait traps. They belonged to four subfamilies, 17 genera, and 32 species. Bait traps caught 29 species, whereas pitfall traps caught 31 species. Bait traps attracted one species not found in pitfall traps, but missed three of the species collected with pitfall traps. Collections from the two sampling methods showed differences in species richness, relative abundance, diversity, and species accumulation curves. Pitfall traps caught significantly more ant species per plot than did bait traps. The ant species diversity obtained from pitfall traps was higher than that from bait traps. Bait traps took a much longer time to complete an estimate of species richness than did pitfall traps. Little information was added to pitfall trapping results by the bait trapping method. The results suggested that the pitfall trapping method is superior to the bait trapping method for leaf litter ant studies. Species accumulation curves showed that sampling of 2,192 plus or minus 532 ants from six plots by pitfall traps provided a good estimation of ant species richness under the conditions of this study.

Evaluation of barley, wheat, and related germplasm yielded only a few accessions with partial resistance. This resistance appears, in most cases, to be under polygenic control, making the development of resistant cultivars with suitable agronomic and quality traits a challenge. The insertion of individual antifungal and antitoxin genes via genetic transformation has the potential to aid in development of resistant wheat and barley cultivars. Although wheat and barley transformation has been achieved in several laboratories, the development of a high throughput wheat and barley transformation systems has been slowed by genotype effects on plant regeneration, low transformation efficiencies, somaclonal variation, and problems with transgene inheritance and stability of expression. Among the antifungal genes targeted to combat FHB are coding sequences for proteins that degrade fungal cell walls, disorganize fungal membranes, bolster the host defense response systems, and interfere with fungal protein synthesis, pathogenesis, and/or accumulation of DON. Promoter sequences have been selected that confer high levels of expression to the antifungal constructs, particularly in the spike tissues which are susceptible to FHB. As more antifungal genes are inserted into wheat and barley, field and greenhouse evaluation will show whether transgenes achieve their potential in the fight against FHB.

The integration of the cecropin MB39 gene into apple was confirmed by Southern blot analysis. Seven independent transgenic lines were recovered from a total of 402 inoculated explants, with a transformation efficiency of 1.7%. Both non-transgenic and transgenic tetraploid plants were produced by treating leaf explants with colchicine at 25 mg l super(-1). Polyploidy was confirmed by flow cytometry. Three of the seven diploid transgenics were significantly more resistant to Erwinia amylovora than the non-transformed Royal Gala control and, in one case, a tetraploid transgenic line was significantly more resistant than the diploid shoot from which it was derived.

A single intratracheal dose of the peptide, H-DDDDDDD-OH (0.5 mg) reduced pulmonary inflammation and the concentration of Mannheimia (Pasteurella) haemolytica in infected lung tissue. Administration of H-DDDDDDD-OH after infection was more effective in reducing the consolidation and lesion scores at the deposition site than its administration prior to infection. Hence, the in vivo effectiveness of AP suggests that it may have applications in the treatment of pulmonary infections. Further studies are needed to confirm these findings and also to determine the optimal doses and intervals of H-DDDDDDD-OH therapy.

Infection was monitored by evaluating symptoms, ELISA, and IC-RT-PCR. Transgenic clone C5 was highly resistant to PPV during four years of testing and displayed characteristics typical of post-transcriptional gene silencing (PTGS), including a high level of transgene transcription in the nucleus, low levels of transgene mRNA in the cytoplasm, a complex multicopy transgene insertion with aberrant copies, and methylation of the silenced PPV-CP transgene.

Establishment and maintenance of high quality turfgrass usually implies substantial inputs of water, nutrients, and pesticides. The focus of this work was to quantify the concentration and loading of a typically maintained municipal turfgrass environment on surface water. Water quantity and quality data were collected from a golf course in Austin, Texas, and analyzed for a 13-month period from March 20, 1998, to April 30, 1999. Twenty-two precipitation events totaling 722 mm, produced an estimated 98 mm of runoff. Nutrient analysis of surface runoff exiting the course exhibited a statistically significant (p < 0.05) increase in median nitrate plus nitrite nitrogen (NO sub(3)+NO sub(2)-N) concentration compared to runoff entering the course, a statistically significant decrease in ammonia nitrogen (NH sub(4)-N), but no difference in ortho-phosphate (PO sub(4)-P). During the 13-month period, storm runoff contributed an estimated 2.3 kg/ha of NO sub(3)+NO sub(2)-N and 0.33 kg/ha of PO sub(4)-P to the stream. Storm flow accounted for the attenuation of 0.12 kg/ha of NH sub(4)-N. Baseflow nutrient analysis showed a statistically significant increase in median NO sub(3)+NO sub(2)-N, a significant reduction in NH sub(4)-N, and no change in PO sub(4)-P. Estimated NO sub(3)+NO sub(2)-N mass in the baseflow was calculated as 4.7 kg/ha. PO sub(4)-P losses were estimated at 0.06 kg/ha, while 0.8 kg/ha of NH sub(4)-N were attenuated in baseflow over the study period. Even though nutrient concentrations exiting the system rarely exceeded nutrient screening levels, this turfgrass environment did contribute increased NO sub(3)+NO sub(2)-N and PO sub(4)-P loads to the stream. This emphasizes the need for parallel studies where management intensity, soil, and climate differ from this study and for golf course managers to utilize an integrated management program to protect water quality while maintaining healthy turfgrass systems.

L.) and thyme (Thymus vulgaris L.) plants were determined after 8 weeks under 350, 1,500, 3,000, 10,000 and 30,000 mu mol mol super(-1) CO2. Plants were grown in vitro on basal medium (BM) consisting of Murashige and Skoog salts and 0.8% agar that contained either 0 or 3% sucrose under a 16-h (day)/8-h (night) photoperiod at a light intensity of 180 mu mol s super(-1)m super(-2) or in soil in a greenhouse under conditions of natural sunlight. Ultra-high CO2 levels (i.e. 3,000 mu mol mol super(-1) CO2) substantially increased fresh weights, leaves, shoots and roots for all plants compared to plants grown under ambient air (350 mu mol mol super(-1) CO2) both in vivo and in vitro. For both species, 10,000 mu mol mol super(-1) CO2 was the optimum concentration to obtain the largest growth and morphogenesis responses under in vitro conditions, while the 3,000- to 10,000- mu mol mol super(-1) CO2 range provided the largest yields for soil-grown plants. Essential oil composition (i.e. monoterpenes, piperitonone oxide and limonene from mint and aromatic phenol and thymol from thyme) from the shoot portion of plants grown at all CO2 levels was analyzed in CH2Cl2 extracts via gas chromatography. Higher levels of secondary compounds occurred in vitro when cultures were grown under ultra-high CO2 levels than in ambient air. The concentration of thymol, a major secondary compound in thyme plants grown on BM containing sucrose, was 317-fold higher at 10,000 mu mol mol super(-1) CO2 than in plants grown under ambient air conditions with the same BM. The levels of secondary compound in in-vitro-grown plantlets exposed to ultra-high CO2 concentrations exceeded those occurring in plants grown in the greenhouse under the same CO2 levels. Substantially higher levels of secondary compound occurred in plants under ultra-high CO2 levels on BM containing sucrose than on BM lacking sucrose or in soil. Thymol levels in thyme plants grown on BM containing sucrose were 3.9-fold higher at 10,000 mu mol mol super(-1) CO2 than in shoots grown on BM without sucrose under the same CO2 levels. High positive correlations occurred between thymol concentrations and CO2 levels, fresh weights, shoots, roots and leaves when thyme shoots were grown on BM with sucrose. High positive correlations for thyme shoots grown on BM without sucrose only occurred between thymol concentrations and CO2 levels, fresh weights, shoots and leaves. No positive correlations between thymol concentrations and CO2 levels or any growth or morphogenesis responses occurred for thyme shoots when grown in soil.

AN - 18091087; 5168873 AB - Uniformly applicable techniques for germplasm preservation are important to the international genetic resources community and validation of techniques among working genebanks will enable the integration of new technologies into plant genetic resources programs. Apical meristems from micropropagated plants of Ribes nigrum L. cv. Ojebyn and R. aureum cv. Red Lake were used to test three cryopreservation protocols (controlled freezing, plant vitrification solution no. 2 (PVS2) vitrification and encapsulation-dehydration) at the USDA-ARS National Clonal Germplasm Repository (NCGR), Corvallis, OR, USA and the University of Abertay Dundee (UAD), Scotland. Similar results were obtained with PVS2 vitrification at both locations but meristem regrowth varied greatly for the other techniques. Variable results between the locations were noted for controlled freezing and were largely attributed to differences in ice crystal initiation by the controlled rate freezers. Low survival of 'Red Lake' at UAD with all three techniques was attributed to poorly performing shoot cultures. Attention to protocol details is important for limiting variation between locations and step by step instructions for procedures and solution preparation aided protocol standardization. These studies suggest that source plant status, cryogenic facilities, and culture conditions may be the most likely causes of variation when validating cryopreservation methodologies in different locations. However, in-house optimization of standard procedures offers considerable potential in ensuring that cryopreservation methodologies can be transferred between international laboratories.

Measures of the invertebrate communities inhabiting rock substrates are often an important component of ecological, monitoring and disturbance studies in streams. A major obstacle to researchers examining rock-inhabiting invertebrates is the time and effort expended on currently used methods of determining rock surface area to derive invertebrate densities on these substrates. In an attempt to more efficiently determine invertebrate densities from rock substrates in streams, we tested a direct method of calculating rock surface area from rock weight or displacement volume. This method allows very quick determinations of rock surface area in the field. Surface area estimates made using this technique were highly correlated to those from a widely used and more time-consuming method. Measurements made using this new method should theoretically give better surface area estimates than any other commonly used technique.

We have immunologically identified Integrin beta sub(1), a promotor of cell-cell adhesion that also induces signals mediating proliferation, differentiation, and apoptosis on the surfaces of cultured Heliothis virescens midgut cells; clusters of immunostained integrin beta sub(1)-like material, indicative of activated integrin, were detected on aggregating midgnt columnar cells. Growth factor-like peptides (midgut differentiation factors 1 and 2 [MDF1 and MDF2]), isolated from conditioned medium containing Manduca sexta midgut cells, may be representative of endogenous midgut signaling molecules. Exposing the cultured midgut cells to Bacillus thuringiensis (Bt) toxin caused large numbers of mature differentiated cells to die, but the massive cell death simultaneously induced a 150-200% increase in the numbers of midgut stem and differentiating cells. However, after the toxin was washed out, the proportions of cell types returned to near-control levels within 2 d, indicating endogenous control of cell-population dynamics. MDF1 was detected immunologically in larger numbers of Bt-treated columnar cells than controls, confirming its role in inducing the differentiation of rapidly produced stem cells. However, other insect midgut factors regulating increased proliferation, differentiation, as well as inhibition of proliferation and adjustment of the ratio of cell types, remain to be discovered.

In the proposed wetland design, water would be diverted from Walker Creek as necessary to maintain wetland function. Therefore, assessment of the magnitude and continuity of the flow from Walker Creek was paramount to successful wetland operation. The Soil and Water Assessment (SWAT) model was used to assess whether the sustained flow (storm flow and base flow) from the Walker Creek Basin could maintain the proposed bottomland wetland ecosystem. For this study, SWAT was modified to allow ponded water within the prescribed wetland to interact with the soil profile and the shallow aquifer. The water budget was prepared for the wetland based on a three-step process. First, data required to run the model on Walker Creek, including soils, topographic, land-use, and daily weather data were assembled. Next, data required to validate the model were obtained. Since stream flow was not available at the proposed site, flow from a nearby watershed with similar soils, land use and topography were used. In the final step, the model was run for 14 years and compared to the measured water balance at the nearby watershed. The model results indicate that the wetland should be at or above 85 percent capacity over 60 percent of the time. The wetland did not dry up during the entire simulated time period (14 years) and reached 40 percent capacity less than one percent of the time during the simulation period. The advantages of the continuous simulation approach used in this study include (1) validation of wetland function (hydroperiod, soil water storage, plant water uptake) over a range of climatic conditions and (2) the ability to assess the long-term impact of land-use and management changes.

ER - TY - JOUR T1 - Generation and Characterization of Recombinant ScFv Antibodies Detecting Eimeria acervulina Surface Antigens AN - 18078942; 5159891 AB - In our previous attempt to generate monoclonal antibodies (MAbs) against coccidia parasites that more accurately reflect the natural avian humoral immune response, we produced two chicken B-cell hybridomas, 5D11 and 2-1. While both cell lines secreted antibodies reactive with sporozoites of Eimeria acervulina, they were produced in yields too low to conduct meaningful in vivo studies. To circumvent this problem, we produced four single chain variable fragment (scFv) antibodies from the V sub(H) and V sub(L) genes of hybridomas 5D11 and 2-1. The concentration of these recombinant antibodies expressed in E. coli and purified to homogeneity was 5-6 mg/L. Three of the antibodies exhibited antigen binding specificity to Eimeria surface antigens equivalent to that of the native MAbs. Nucleotide sequence analysis of the V sub(L) genes from hybridomas 5D11 and 2-1 and genomic DNA revealed vestiges of gene conversion with V sub( lambda ) pseudogenes. These recombinant scFv antibodies will prove useful for further characterization of natural Eimeria surface antigens as potential vaccine candidates.

Four 8-ha sites on the Allegheny National Forest were sampled monthly from May to August in 1992 and 1993 for herbaceous layer species composition and percent cover. Each site included 60 circular 4-m super(2) plots. Fifteen tally combinations created by combining sample times (1, 2, 3 and 4 at a time) were used to generate diversity indices. Herbaceous species in Allegheny hardwood forests were categorized as common or infrequent. Common plants were present throughout the growing season and their abundance remained stable. Infrequent plants differed in abundance and presence throughout the study. Coverage of several plants increased from May to July as they became fully developed. Species richness increased with number of sample times. The Shannon Diversity index and the Shannon Evenness index did not show differences attributable to time of sampling. Sampling for herbaceous species diversity in Allegheny hardwood forests should include two inventories, one early and one late in the growing season.

A second hypothesis was that fungi isolated from saline soil are more effective in counteracting salt effects than those from nonsaline soil. VAM fungi from high- and low-salt soils were trap-cultured, their propagules quantified and adjusted to a like number, and added to a pasteurized soil mix in which seedlings were grown for 3-4 weeks. Once the seedlings were colonized by VAM fungi, they were transplanted into salinized (NaCl) soil. Preinoculated lettuce transplants grown for 11 weeks in the saline soils had greater shoot mass compared with nonVAM plants at all salt levels [2 (control), 4, 8 and 12 dS m super(-1)] tested. Leaves of VAM lettuce at the highest salt level were significantly greener (more chlorophyll) than those of the nonVAM lettuce. NonVAM onions were stunted due to P deficiency in the soil, but inoculation with VAM fungi alleviated P deficiency and salinity effects; VAM onions were significantly larger at all salt levels than nonVAM onions. In a separate experiment, addition of P to salinized soil reduced the salt stress effect on nonVAM onions but to a lesser extent than by VAM inoculation. VAM fungi from the saline soil were not more effective in reducing growth inhibition by salt than those from the nonsaline site. Colonization of roots and length of soil hyphae produced by the VAM fungi decreased with increasing soil salt concentration. Results indicate that preinoculation of transplants with VAM fungi can help alleviate deleterious effects of saline soils on crop yield.

(Pinaceae). We investigated the existence of heritable differences in two life-history parameters (adult size and development time) of D. ponderosae from a northern population (central Idaho, Pinus contorta Douglas ex Loudon) and a southern population (southern Utah, Pinus ponderosa Douglas ex P. and C. Lawson). We attempted to separate heritable from environment effects by rearing individuals from both populations through two generations (F sub(1) and F sub(2)) in a common standardized laboratory environment with a constant temperature. Two treatment effects were tested for in the F sub(2) generation: geographic location (source host) for F sub(0) D. ponderosae; and the F sub(2) brood host. We hypothesized that, if differences were observed and the F sub(0) source host and region had a greater effect on F sub(2) brood development time and adult size than did the host in which F sub(2) brood were reared, a heritable factor related to the F sub(0) parents was responsible. Time to emergence was significantly shorter for second-generation offspring of the northern population than for second- generation offspring of the southern population, regardless of the F sub(2) brood host. Although both the F sub(2) brood host and F sub(0) source parents were significant in explaining differences observed in the developmental-time distribution of F sub(2) brood, the F sub(0) source effect was found to be much greater. Also F sub(2) males and females from southern source parents were significantly larger than F sub(2) brood from northern source parents when reared in both F sub(2) brood hosts. Geographic region and original host F sub(0) source parents had a significant effect on F sub(2) offspring size, whereas the immediate food for F sub(2) brood was not significant in explaining differences. These results suggest genetically based regional differences in D. ponderosae populations.

Topographic conditions (elevation, landform index, surface curvature, slope gradient and aspect) and proximity to coniferous cover were evaluated for three study areas where flying squirrel presence has been documented via nest box surveys. In our model, Virginia northern flying squirrel presence was associated with proximity to conifer cover (P < 0.001), but not to any other habitat variables tested. We developed a logistic regression model and implemented that within a geographic information system to delineate potential habitat. Statistical relations were not sufficient to predict flying squirrel occurrence with a reasonable degree of confidence. Current nest box monitoring efforts provide needed year-to-year population trend information, however, they are not sufficient to delineate potential habitat using quantitative approaches. More detailed micro- and macro-habitat relationship studies of the Virginia northern flying squirrel will be necessary for successful management and eventual recovery of this endangered species.

These reactions generate extracellular Fenton reagent, which enables G. trabeum to degrade a wide variety of organic compounds. We found that G. trabeum secreted two quinones, 2,5-dimethoxy-1,4-benzoquinone (2,5-DMBQ) and 4,5-dimethoxy-1,2-benzoquinone (4,5-DMBQ), that underwent iron-dependent redox cycling. Experiments that monitored the iron- and quinone-dependent cleavage of polyethylene glycol by G. trabeum showed that 2,5-DMBQ was more effective than 4,5-DMBQ in supporting extracellular Fenton chemistry. Two factors contributed to this result. First, G. trabeum reduced 2,5-DMBQ to 2,5-dimethoxyhydroquinone (2,5-DMHQ) much more rapidly than it reduced 4,5-DMBQ to 4,5-dimethoxycatechol (4,5-DMC). Second, although both hydroquinones reduced ferric oxalate complexes, the predominant form of Fe super(3+) in G. trabeum cultures, the 2,5-DMHQ-dependent reaction reduced O sub(2) more rapidly than the 4,5-DMC-dependent reaction. Nevertheless, both hydroquinones probably contribute to the extracellular Fenton chemistry of G. trabeum, because 2,5-DMHQ by itself is an efficient reductant of 4,5-DMBQ.

They showed that live offspring of a mammal other than the mouse could in fact be produced after the extensive in vitro manipulations required for gene targeting. In this issue, John Clark and colleagues attempt to repeat the targeting/cloning technology at two additional genetic loci. They report the "knockout" of the alpha 1,3-galactosyltransferase gene, GGTA1, which encodes a protein involved in acute rejection of xenotransplanted organs, and the prion protein gene, PrP, which is required for transmissible spongiform encephalopathy (TSE). Although the production of genetically engineered animals lacking either of these genes could have a profound positive impact on agriculture and/or medicine, the report raises questions as to whether new approaches will be needed to routinely reap the benefits of this technology.

AN - 17903697; 5148410 AB - Bioassays were conducted to examine the response of Coptotermes formosanus Shiraki and Reticulitermes flavipes (Kollar) to whole body extracts of termites. Bioassays were also conducted to determine if trail-following behavior could be elicited in glass tubes after different lengths of exposure to termites and if termites showed any species-specific response to exposed tubes. Trail-following behavior was elicited in both species in response to whole body extracts of their nestmates. Although C. formosanus responded to the R. flavipes extract, R. flavipes did not show a difference in response to the C. formosanus extract versus solvent-treated controls. Trail-following behavior was elicited in both C. formosanus and R. flavipes by glass tubes exposed to termites for 5 min. Although neither species showed a preference for glass tubes exposed to their nestmates over tubes exposed to termites of the other species, there were differences in the persistency of trail-following substances deposited in tubes by the two species. When tubes were exposed to termites for 5 min, trail-following behavior was elicited by tubes exposed to C. formosanus for at least 1 h after exposure, whereas termites no longer responded to tubes that were exposed to R. flavipes 10-15 min after exposure. When tubes were exposed to termites for 14 d, termites deposited chemical markers which lasted for at least 8 d. There was no difference in the response of C. formosanus to tubes exposed to their nestmates versus tubes exposed to R. flavipes. However, R. flavipes showed a significant preference for tubes exposed to their nestmates over tubes exposed to C. formosanus. Because there was no evidence of a species-specific response by R. flavipes to tubes exposed to termites for only 5 min, it is possible that chemicals in the feces or in salivary secretions deposited in tubes influenced the behavior of R. flavipes in tests using tubes exposed to termites for 14 d.

Scouting cotton for egg masses is commonly recommended for identifying potential outbreaks and for proper timing of insecticide applications. However, there is disagreement regarding where to look on the plant for beet armyworm eggs. We investigated and quantified placement of egg masses by laboratory colony females within cotton and pigweed (a preferred wild host plant) canopies of different heights. In cotton, almost all egg masses were deposited on the undersides of leaves, and approximately 80% of the egg masses were consistently located in the upper 50% of the cotton canopy, and horizontally within the inner 50% of the canopy around the central axis. Although this trend was consistent among all categories of plant height tested, variation about the means decreased with increasing height. A smaller sample of wild females indicated similar vertical placement, but horizontal placement extending further distally in the canopy. Our results indicate that scouting for egg masses on the underside of leaves in the upper half of the canopy will recover approximately 80% of the egg masses present on the plants. In pigweed, egg masses were commonly laid within the inner 50% of the canopy, but along the upper 80% of the vertical axis. As in cotton, variation about the means was less in taller plants. The number of eggs per egg mass was 29% less in cotton than in pigweed. This positional information will aid in further efforts to investigate, predict, and manage beet armyworm populations in cotton and noncotton hosts.

This study examined the host range of A. samarensis. We used three approaches: (1) field collection and rearing of potential alternate or alternative hosts at European sites where A. samarensis was known to occur, (2) choice tests offering females of A. samarensis both gypsy moth and native North American species of Lepidoptera, and (3) host suitability tests in which we artificially inoculated European nontarget species with mature eggs of A. samarensis dissected from gravid females. In the field studies, we collected a total of 851 caterpillars, belonging to at least 54 species other than gypsy moth in 11 families, over several years, but none yielded A. samarensis, with the possible exception of a single larva of Lymantria monacha (L.) and the rusty tussock moth, Orgyia antiqua (L.), which yielded puparia resembling those of A. samarensis. In laboratory tests, we offered females of A. samarensis 11 native species of North American Lepidoptera in five families, but only the lymantriid Orgyia leucostigma (J. E. Smith), was successfully parasitized. In host suitability studies, we inoculated 10 species of Lepidoptera in eight families with mature eggs of A. samarensis, but parasitism was successful only in L. dispar. We conclude that A. samarensis has a high degree of host specificity.

Murray), two elm cultivars (Ulmus spp.), and an American elm clonal selection (U. americana L.), and was related to the leaf content of important nutritional elements. Significantly more eggs were laid and more nymphs became adults on American and Patriot elms than on the other clones. Although the mean number of eggs laid was not significantly different among the maple clones, nymphal survivorship was significantly higher on red maple 56026 than on the other maple clones. Although the number of eggs laid was linearly related to foliar nitrogen and phosphorus, survival of nymphs to adulthood was linearly related to foliar nitrogen. Significantly more leafhoppers from the wild population were collected from American elm, followed by Patriot elm and red maple 56026. Although none of the elms showed any evidence of feeding injury, the maple trees varied from tolerant (i.e., 'Indian Summer') to susceptible (i.e., red maple 56026). Leafhoppers may need to increase feeding on red maple 56026 as a compensatory response to the limited nutritional quality of this clone. Because the sex ratio of the wild population was close to 1:1, and consistent across clones, it appears that differences in the behavior of the potato leafhopper among clones were not a function of gender bias associated with each species. Resistance against the potato leafhopper among maples and elms is influenced, in part, by the nutritional content of the leaves. Yet, feeding injury is not a good indicator of host resistance against the potato leafhopper.

We investigated the sensitivity of P. l. larvae to 27 antibiotics, which were primarily ones already registered with the US Food and Drug Administration for agricultural uses. Bacterial resistance to OTC also conferred resistance to other tetracyclines, although the level of resistance varied. The most active antibiotics screened that are currently used in agriculture were erythromycin, lincomycin, monensin, and tylosin. Rifampicin was by far the most active antibiotic tested, but since it is used against tuberculosis, registration of this material for agricultural use is unlikely.

Since then, chemical control has been needed. Moderate resistance of a slow-mildewing type is known and has been used commercially. High resistance was identified recently in B. vulgaris subsp. maritima accessions WB97 and WB242 and has been backcrossed into sugar beet breeding lines. These enhanced lines were used as sources of powdery mildew resistance to determine the inheritance of resistance. Analyses of segregating test-cross families showed that resistance from both sources is inherited as a single, dominant, major gene. The gene symbol Pm is proposed for the resistant allele. The allelism of the resistance from the two wild beet sources was not determined. Pm conditions a high level of resistance, but disease developed on matured leaves late in the season. This late development of mildew on lines and the slow-mildewing trait in susceptible, recurrent lines tended to obfuscate discrete disease ratings.

Adjacent areas were compared at 1, 7, 12, and 17 years following two reproduction cutting methods (clearcuts or pine seed-tree cuts); a 59-year-old pine stand that was periodically thinned was also included to represent conditions before reproduction cutting. Because average or better natural loblolly and shortleaf pine (Pinus taeda L. and P. echinata Mill.) seed crops coincided with the planned site disturbances, pines dominated the seedling-size classes at 1 and 7 years after reproduction cutting, the sapling-size classes at 7, 12, and 17 years after reproduction cutting, and the small- and large-tree size classes at 12, 17, and 59 years after reproduction cutting. For seedling-size classes, three measures of woody plant diversity (Shannon's (H'), Simpson's (D), and evenness (e) indices) tended to increase from 1 to 12 years after reproduction cutting. In the sapling-size classes, H' and D diversity indices were highest at 17 years and lowest at 59 years after reproduction cutting. For small-tree size classes, H', and D were highest at 7 years and lowest at 12 years after reproduction cutting. Across all but the large-tree size classes, woody species richness peaked 7 years after reproduction cutting. Naturally regenerated pines achieved complete crown closure by 17 years after reproduction cutting; consequently, the presence of shade-tolerant woody plants increased in the understory, and shade-intolerant herbaceous plants disappeared from the forest floor.

Flexibility in forest management reflects both the relative rigidity of intervention requirements and the potential range of development pathways for a stand. The wind stability of Pacific Northwest Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) plantations is used to demonstrate the concept of management flexibility. Dense Douglas-fir plantations develop high height to diameter ratios (H/D same units) in the dominant trees making them unstable and prone to wind damage. The management of these plantations is inflexible, because without early and timely thinning, the stands do not contain stable trees that could be expected to survive long rotations or late thinnings. A combination of reduced planting densities and site-specific management reduces both the necessity and rigidity of intervention requirements (e.g., thinning) and expands the number of potential developmental pathways for these stands. The cost of greater management flexibility is reduced efficiency of wood volume production; however, greater adaptability to changing markets, labor conditions, and management objectives may be more important for many forest owners. While this approach to management is complex, it frees owners and managers from rigid management requirements and allows for a wider range of future stand conditions.

Here we show that the process of drying and rapidly rewetting soil increases the amount of water-soluble phosphorus present and that this is predominantly in organic form after having been released from the soil microbial biomass. This effect could not only significantly affect phosphorus pollution of waterbodies but might also corrupt results from analyses involving water extraction of dried soils.

The techniques for measuring soil erosion patterns and sediment redistribution within plots or watersheds by direct monitoring are very limited. The objective of this study was to develop a direct and non-intrusive tracer method to study the sources, patterns and rates of erosion and deposition of sediments in erosion plots. The magnetic tracer developed in this study consisted of polystyrene plastic beads embedded with a magnetic powder (magnetite). The "magnetized" beads, with a mean weight diameter of 3.2 mm and particle density of about 1.2 g cm super(-3), were uniformly mixed with soil and tested in the laboratory using simulated rainfall and inflow studies to simulate the interrill and rill components of soil erosion, respectively. In the interrill and rill experiments, the tracer was transported in the same proportion it was initially mixed with the soil. Given this fact, a magnetometer, which measures the soil's magnetic susceptibility, could be used to identify areas of deposition or detachment. The magnetic susceptibility would be increased or reduced depending on whether deposition or detachment occurs. To simulate detachment and deposition, a magnetometer was tested for different tracer concentrations and different thickness of soil containing the tracer. The magnetometer promises to be a sensitive, accurate, and useful tool to study the spatial variation of soil erosion when magnetic tracers are used.

These data revealed striking patterns of partial and selective consumption that varied with relative availability and attributes of the fish. As the availability of salmon decreased, bears consumed a larger proportion of each fish among both years and habitats. When availability was high (absolute number and density of salmon), bears consumed less biomass per captured fish, targeting energy-rich fish (those that had not spawned) or energy-rich body parts (eggs in females; brain in males). In contrast, individual fish were consumed to a much greater extent, regardless of sex or spawning status, in habitats or years of low salmon availability. The proportion of biomass consumed per fish was similar for males and females, when spawning status was statistically controlled, but bears targeted different body parts: the body flesh, brain and dorsal hump in males and the roe in females. Bears thus appeared to maximize energy intake by modifying the amount and body parts consumed, based on availability and attributes of spawning salmon.

Using three scales of resolution, we examine the importance of a long-lived desert tree, ironwood (Olneya tesota), in structuring plant communities and promoting biological diversity in the Sonoran Desert. We examined the positive effects of Olneya canopies of different sizes on plant communities in mesic and xeric habitats throughout the central Gulf Coast subregion of Sonora, Mexico. In xeric sites, Olneya canopies had strong positive effects on plant richness and abundance, and small positive effects on the size of plants, underscoring the role of facilitation in extreme environments. In mesic sites, Olneya canopies had very little effect on perennials and a negative effect on ephemeral richness, suggesting predominantly competitive effects in this less stressful environment. Overall, Olneya canopies increased biological diversity where abiotic stress was high, but did not increase diversity in more mesic areas. Thus Olneya canopies caused consistent shifts in plant-community structure among xeric and mesic sites, but not when these landscapes were combined. Benefactor size also mediated positive interactions, with larger Olneya canopies supporting larger perennials in both xeric and mesic sites. Thus stress gradients and benefactor size both influenced the balance of facilitative and competitive effects under nurse-plant canopies, and the spatial scale at which facilitative effects shape community structure.

A model proposed by Selin and Chavez suggests that collaboration emerges from a series of antecedents and then proceeds sequentially through problem-setting, direction-setting, implementation, and monitoring and evaluation phases. This paper summarizes an empirical study to evaluate if the Selin and Chavez model encompasses the range of factors important for the establishment and operation of collaboration in watershed planning from the perspective of the planning coordinator. Analysis of three case studies of watershed based planning efforts in the Intermountain West suggests the model realistically describes some of the fundamental collaborative elements in watershed planning. Particularly important factors include the involvement of stakeholders in data collection and analysis and the establishment of measurable objectives. Informal face-to-face dialog and watershed field tours were considered critical for identifying issues and establishing trust among stakeholders. Group organizational structure also seems to play a key role in facilitating collaboration. From this analysis, suggestions for refining the model are proposed.

AN - 71041713; 11471940 AB - A strain of the fungus Fusarium equiseti isolated from soybean cyst nematode secretes nematode-antagonistic compounds. Bioassay-guided fractionation of an extract of the culture broth was undertaken to identify the compounds. Fractions were assayed for activity against a root-knot nematode (Meloidogyne incognita), a plant pathogen that attacks the roots of numerous plant species. Two trichothecene compounds were isolated that inhibited egg hatch and immobilized second-stage juveniles of this nematode: 4,15-diacetoxy-12,13-epoxy-3,7-dihydroxytrichothec-9-en-8-one (4,15-diacetylnivalenol) and 4,15-diacetoxy-12,13-epoxy-trichothec-9-en-3-ol (diacetoxyscirpenol). This is the first published report of these compounds affecting plant-parasitic nematodes.

AN - 70929963; 11417641 AB - The statistical distribution known as the compound gamma function was studied for suitability in describing the distribution of sample test results associated with testing lots of shelled corn for fumonisin. Thirty-two 1.1 kg test samples were taken from each of 16 contaminated lots of shelled corn. An observed distribution consisted of 32 sample fumonisin test results for each lot. The mean fumonisin concentration, c, and the variance, s2, among the 32 sample fumonisin test results along with the parameters for the compound gamma function were determined for each of the 16 observed distributions. The 16 observed distributions of sample fumonisin test results were compared with the compound gamma function using the Power Divergence test. The null hypothesis that the observed distribution could have resulted from sampling a family of compound gamma distributions was not rejected at the 5% significance level for 15 of the 16 lots studied. Parameters of the compound gamma distribution were calculated from the 32-fumonisin sample test results using the method of moments. Using regression analysis, equations were developed that related the parameters of the compound gamma distribution to fumonisin concentration and the variance associated with a fumonisin test procedure. An operating characteristic curve was developed for a fumonisin sampling plan to demonstrate the use of the compound gamma function.

AN - 70902512; 11401247 AB - Phosphorus (P) often limits the eutrophication of streams, rivers, and lakes receiving surface runoff. We evaluated the relationships among selected soil P availability indices and runoff P fractions where manure, whey, or commercial fertilizer applications had previously established a range of soil P availabilities on a Portneuf silt loam (coarse-silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid) surface-irrigated with Snake River water. Water-soluble P, Olsen P (inorganic and organic P), and iron-oxide impregnated paper-extractable P (FeO-Ps) were determined on a 0.03-m soil sample taken from the bottom of each furrow before each irrigation in fall 1998 and spring 1999. Dissolved reactive phosphorus (DRP) in a 0.45-microm filtered runoff sample, and iron-oxide impregnated paper-extractable P (FeO-Pw), total P, and sediment in an unfiltered runoff sample were determined at selected intervals during a 4-h irrigation on 18.3-m field plots. The 1998 and 1999 data sets were combined because there were no significant differences. Flow-weighted average runoff DRP and FeO-Pw concentrations increased linearly as all three soil P test concentrations increased. The average runoff total P concentration was not related to any soil P test but was linearly related to sediment concentration. Stepwise regression selected the independent variables of sediment, soil lime concentration, and soil organic P extracted by the Olsen method as related to average runoff total P concentration. The average runoff total P concentration was 1.08 mg L(-1) at a soil Olsen P concentration of 10 mg kg(-1). Soil erosion control will be necessary to reduce P losses in surface irrigation runoff.

AN - 70855510; 11359703 AB - Fusarium moniliforme Sheldon, a biological species of the mating populations within the (italic)Gibberella fujikuroi species complex, i.e., population A [= G. moniliformis (Sheld.) Wineland], is an example of a facultative fungal endophyte. During the biotrophic endophytic association with maize, as well as during saprophytic growth, F. moniliforme produces the fumonisins. The fungus is transmitted vertically and horizontally to the next generation of plants via clonal infection of seeds and plant debris. Horizontal infection is the manner by which this fungus is spread contagiously and through which infection occurs from the outside that can be reduced by application of certain fungicides. The endophytic phase is vertically transmitted. This type infection is important because it is not controlled by seed applications of fungicides, and it remains the reservoir from which infection and toxin biosynthesis takes place in each generation of plants. Thus, vertical transmission of this fungus is just as important as horizontal transmission. A biological control system using an endophytic bacterium, Bacillus subtilis, has been developed that shows great promise for reducing mycotoxin accumulation during the endophytic (vertical transmission) growth phase. Because this bacterium occupies the identical ecological niche within the plant, it is considered an ecological homologue to F. moniliforme, and the inhibitory mechanism, regardless of the mode of action, operates on the competitive exclusion principle. In addition to this bacterium, an isolate of a species of the fungus Trichoderma shows promise in the postharvest control of the growth and toxin accumulation from F. moniliforme on corn in storage.

AN - 70853561; 11368614 AB - Single-strength orange juice was irradiated with 0, 0.89, 2.24, 4.23, and 8.71 gGy of gamma radiation at 5 degrees C and then stored at 7 degrees C for 21 days. Volatile compounds, isolated by solid-phase microextraction, were separated and identified using a gas chromatograph equipped with a mass selective detector. The majority of the volatile compounds were terpenes, and the most abundant volatile compounds were ethanol and limonene. Most volatile compounds were stable during the 21-day storage period except geranial and neral which decreased over time. Irradiation reduced the concentration of acyclic monoterpenes, such as geranial, neral, myrcene, and linalool 1 and 7 days after irradiation, but did not affect other monoterpenes, sesquiterpenes, or other volatile compounds. The reduction of acyclic monterpenes increased linearly with radiation dose, and correlated with an increase in thiobarbituric acid reactive substrates (TBARS) content. Reduction in the concentration of monoterpenes induced by irradiation was not significant 21 days after irradiation. Our results indicate that acyclic monoterpenes are sensitive to irradiation whereas most other volatile compounds are resistant.

AN - 70846956; 11368573 AB - The determination of the levels of pesticides in food products has prompted the development of sensitive and rapid methods of analysis that are solvent-free or utilize solvents that are benign to the environment and laboratory worker. In this study we have developed a novel extraction method that utilizes ethanol-modified subcritical water in combination with solid-phase microextraction (SPME) for the removal of atrazine from beef kidney. In situ sample cleanup was achieved using the technique of matrix solid-phase dispersion. A cross-linked polymer, XAD-7 HP, was utilized as a dispersing material for kidney samples. Subcritical water extractions were performed with a pressurized solvent extraction unit at 100 degrees C and 50 atm. Experimental parameters investigated were the volume of solvent and amount of modifier required for the complete extraction of atrazine and optimization of the extraction time. It was determined that 30% ethanol in water (v/v) is adequate for the complete extraction of atrazine. A Carbowax-divinylbenzene SPME fiber was used to sample the aqueous extracts. Analysis of the fiber contents was by ion-trap GC/MS utilizing the single ion mode. The total time of analysis for a single kidney sample is 90 min. The average percent recoveries from samples spiked to the concentrations of 2 and 0.2 microg/g were 104 and 111, respectively. The average relative standard deviations were 10 and 9, respectively. The method limit of detection for beef kidney spiked with atrazine was found to be 20 ng/g of sample.

AN - 70844321; 11359699 AB - There is a great deal of evidence that altered sphingolipid metabolism is associated with fumonisin-induced animal diseases including increased apoptotic and oncotic necrosis, and carcinogenesis in rodent liver and kidney. The biochemical consequences of fumonisin disruption of sphingolipid metabolism most likely to alter cell regulation are increased free sphingoid bases and their 1-phosphates, alterations in complex sphingolipids, and decreased ceramide (CER) biosynthesis. Because free sphingoid bases and CER can induce cell death, the fumonisin inhibition of CER synthase can inhibit cell death induced by CER but promote free sphingoid base-induced cell death. Theoretically, at any time the balance between the intracellular concentration of effectors that protect cells from apoptosis (decreased CER, increased sphingosine 1-phosphate) and those that induce apoptosis (increased CER, free sphingoid bases, altered fatty acids) will determine the cellular response. Because the balance between the rates of apoptosis and proliferation is important in tumorigenesis, cells sensitive to the proliferative effect of decreased CER and increased sphingosine 1-phosphate may be selected to survive and proliferate when free sphingoid base concentration is not growth inhibitory. Conversely, when the increase in free sphingoid bases exceeds a cell's ability to convert sphinganine/sphingosine to dihydroceramide/CER or their sphingoid base 1-phosphate, then free sphingoid bases will accumulate. In this case cells that are sensitive to sphingoid base-induced growth arrest will die and insensitive cells will survive. If the cells selected to die are normal phenotypes and the cells selected to survive are abnormal, then cancer risk will increase.

AN - 70838358; 11347989 AB - Reconstituted orange juice inoculated with Salmonella Anatum, Salmonella Infantis, Salmonella Newport, or Salmonella Stanley was treated with gamma radiation at 2 degrees C. To determine the relationship between juice antioxidant power and Dgamma (dose required to achieve 90% mortality), juice solids were removed prior to inoculation by centrifugation and/or filtration to create juice preparations of varying turbidity. In unadulterated orange juice, Salmonella Anatum (Dgamma = 0.71 kGy) was significantly more resistant than the other species tested. Salmonella Newport (Dgamma = 0.48 kGy) and Salmonella Infantis (Dgamma = 0.35 kGy) were significantly different, while Salmonella Stanley (Dgamma = 0.38 kGy) was intermediate between the two. Neither the resistance of each isolate nor the pattern of relative resistance among isolates was altered in reduced turbidity juice preparations. Although total antioxidant power was associated with the level of juice solids resuspended in phosphate buffer, antioxidant power was not significantly associated with turbidity in the juice preparations or with Dgamma of any species. The variable resistance to irradiation of the Salmonella isolates suggests this as a more significant factor than turbidity or antioxidant power in designing antimicrobial juice irradiation protocols.

AN - 70796805; 11319078 AB - To further develop genetic techniques for the enteropathogen Brachyspira hyodysenteriae, the gyrB gene of this spirochete was isolated from a lambdaZAPII library of strain B204 genomic DNA and sequenced. The putative protein encoded by this gene exhibited up to 55% amino acid sequence identity with GyrB proteins of various bacterial species, including other spirochetes. B. hyodysenteriae coumermycin A(1)-resistant (Cn(r)) mutant strains, both spontaneous and UV induced, were isolated by plating B204 cells onto Trypticase soy blood agar plates containing 0.5 microg of coumermycin A(1)/ml. The coumermycin A(1) MICs were 25 to 100 microg/ml for the resistant strains and 0.1 to 0.25 microg/ml for strain B204. Four Cn(r) strains had single nucleotide changes in their gyrB genes, corresponding to GyrB amino acid changes of Gly(78) to Ser (two strains), Gly(78) to Cys, and Thr(166) to Ala. When Cn(r) strain 435A (Gly(78) to Ser) and Cm(r) Km(r) strain SH (DeltaflaA1::cat Deltanox::kan) were cultured together in brain heart infusion broth containing 10% (vol/vol) heat-treated (56 degrees C, 30 min) calf serum, cells resistant to chloramphenicol, coumermycin A(1), and kanamycin could be isolated from the cocultures after overnight incubation, but such cells could not be isolated from monocultures of either strain. Seven Cn(r) Km(r) Cm(r) strains were tested and were determined to have resistance genotypes of both strain 435A and strain SH. Cn(r) Km(r) Cm(r) cells could not be isolated when antiserum to the bacteriophage-like agent VSH-1 was added to cocultures, and the numbers of resistant cells increased fivefold when mitomycin C, an inducer of VSH-1 production, was added. These results indicate that coumermycin resistance associated with a gyrB mutation is a useful selection marker for monitoring gene exchange between B. hyodysenteriae cells. Gene transfer readily occurs between B. hyodysenteriae cells in broth culture, a finding with practical importance. VSH-1 is the likely mechanism for gene transfer.

However, to parameterize these models requires an understanding of the spatial variability of erosion processes and the particle sizes of the sediment being moved. In this study, a high resolution digital elevation model (DEM) and detailed sediment particle sampling allowed a comparison of hillslope characteristics and particle sizes of surficial armoring in a semiarid watershed. Individual particle size classes on hillslopes are correlated with the underlying sediment type, local slope, aspect, and area draining through a grid element. The strongest correlations are between the underlying sediment and overlying sediment. However, the distribution of the particle size classes is consistent with a hydrodynamic explanation for sorting. In particular, increased area draining through a grid node and increased slope are correlated with higher concentrations of the 16-64-mm particle size class. Both the coarsest and finest particle size classes are significantly correlated with the aspect of flow from a grid cell, with increased coarse particles and decreased fines on east-facing slopes. These spatial differences with aspect are attributed to dry season prevailing winds. These observations about process and spatial distribution are useful in predicting the spatial distribution of particles on the watershed for applications such as distributed hydrologic models.

They cause fatal toxicoses of horses and swine. Their effects in humans are unclear, but epidemiologic evidence suggests that consumption of fumonisin-contaminated corn contributes to human esophageal cancer in southern Africa and China. Much has been learned from rodent studies about fumonisin B1(FB1), the most common homologue. FB1 is poorly absorbed and rapidly eliminated in feces. Minor amounts are retained in liver and kidneys. Unlike other mycotoxins, fumonisins cause the same liver cancer promotion and subchronic (studies (3/4) 90 days) liver and kidney effects as F. moniliforme. FB 1 induces apoptosis of hepatocytes and of proximal tubule epithelial cells. More advanced lesions in both organs are characterized by simultaneous cell loss (apoptosis and necrosis) and proliferation (mitosis). Microscopic and other findings suggest that an imbalance between cell loss and replacement develops, a condition favorable for carcinogenesis. On the molecular level, fumonisins inhibit ceramide synthase, and disrupt sphingolipid metabolism and, theoretically, sphingolipid-mediated regulatory processes that influence apoptosis and mitosis. Liver sphingolipid effects and toxicity are correlated, and ceramide synthase inhibition occurs in liver and kidney at doses below their respective no-observed-effect levels. FB1 does not cross the placenta and is not teratogenic in vivoin rats, mice, or rabbits, but is embryotoxic at high, maternally toxic doses. These data have contributed to preliminary risk evaluation and to protocol development for carcinogenicity and chronic toxicity studies of FB1 in rats and mice.

ER - TY - JOUR T1 - Mode of reproduction and amplified fragment length polymorphism variation in purple needlegrass (Nassella pulchra): utilization of natural germplasm sources AN - 18256370; 5308630 AB - A dominant plant of the California grasslands, purple needlegrass [Nassella pulchra (Hitchc.) Barkworth] is an important revegetation species in its native range. The amplified fragment length polymorphism (AFLP) method was used to elucidate mode of reproduction and nucleotide variation among 11 natural populations and three selected natural germplasm releases of N. pulchra. A total of 12 co-dominant AFLPs, informative within eight populations, failed to reveal any heterozygous individuals, indicating very high selfing rates (S sub(H) = 1). Estimates of nucleotide diversity within populations ranged from 0 to 0.00069 (0.00035 average), whereas the total nucleotide divergence among populations ranged from 0.00107 to 0.00382 (0.00247 average). Measures of population differentiation (G sub(S)) in terms of Shannon-Weaver diversity values and estimated nucleotide substitutions were 0.90 and 0.86, respectively. Although some of the sample populations contained a mixture of true breeding genotypes, most populations could be distinguished unambiguously. Moreover, geographical distance between the natural source populations was significantly correlated with genetic distance (r = 0.60) among the corresponding sample populations. Results indicate that inbreeding, combined with founder effects and/or selection, has contributed to the differentiation of N. pulchra populations. Foundation seed populations of the selected natural germplasm releases were genetically well defined and most similar to natural seed collected near the corresponding source populations. Thus, these commercial germplasm sources will be made practically available and useful for conservation plantings within the intended areas of utilization.

This study was conducted to quantify and compare CH sub(4) fluxes from a variet of ecosystems in central Iowa. We investigated agricultural systems under different management practices, a hardwood forest site, native and restored prairies, and a municipal landfill. Flux measurements were obtained using a closed-chamber method, and measurements were compiled by sampling over the 1993 and 1994 growing seasons. In 1993, most of the agricultural sites were net CH sub(4) producers with cumulative CH sub(4) fluxes ranging from -0.02 to 3.19 g m super(-2) over the 258-d sampling season, while the natural ecosystems were net CH sub(4) consumers, with cumulative seasonal fluxes ranging from -0.27 to -0.07 g m super(-2) 258 d super(-1). In 1994, only the landfill and the agricultural site treated with broadcast liquid swine manure (LSM) were net CH sub(4) producers, while the remainder of the natural and agricultural ecosystems were net CH sub(4) consumers, with mean seasonal flux rates ranging from -0.43 to -0.008 g m super(-2) 271 d super(-1). We hypothesize that the differences in CH sub(4) fluxes between the two years are due to differences in rainfall. To illustrate the integration between land use and CH sub(4) flux, we computed an area-weighted soil CH sub(4) flux for the state of Iowa. Our calculations yielded a net average soil CH sub(4) flux of 139 000 Mg CH sub(4) for 1993 and 1994.

Cells were plated and maintained in 10% fetal bovine serum from day 0 to day 3 and then switched to serum-free medium from day 3 to day 6 to induce lipid filling. On days 3 and 6 of culture, some of the cells were lysed for ligand and immunoblotting and the remainder subjected to competitive and inhibitory-binding assays. Media from day 6 of culture were subjected to ligand and immunoblotting. Competitive binding analysis showed one-site bindings, with IC sub(50)s in the nanomolar and K sub(d)s in the picomolar ranges, that were not significantly different at both time-points of measurement. However, the B sub(max) decreased significantly with differentiation. Preincubation with antibody against TNF receptor type 1 (TNFR1) or TNF receptor type 2 reduced the specific binding by 95 and 15%, respectively, suggesting a dominating role of TNFR1 in super(125)I-labeled TNF alpha ( super(125)I-TNF alpha ) binding. This was further supported by ligand blotting of cell lysates. Ligand and immunoblotting of cell lysates indicated that TNF alpha utilizes both types of surface receptors and their isoforms which were not modified during differentiation. Ligand blotting of media revealed soluble receptors with high M sub(r) implying the formation of multimers. Immunoblotting suggested the presence of both types of TNFRs, but a greater abundance of soluble TNFR1. Also, it indicated the additional formation of smaller oligomers from both types of soluble receptors suggesting higher affinity of larger multimers for super(125)I-TNF alpha .

All parameters were significantly reduced for the water-only diet compared with 10% honey or sucrose diets, except fertility, which could not be measured after 5 d because of high mortality of water-fed females. Oviposition was highest the night after mating and decreased in a logarithmic manner thereafter. In the carbohydrate-fed moths, 92% of lifetime realized fecundity occurred by the fourth night of oviposition. Although our data indicate that carbohydrates in the adult diet can increase realized and potential fecundity, most of the lifetime complement of oocytes (91%) is present at the time of eclosion from the pupa. Pupal weight was significantly correlated with lifetime potential fecundity, explaining 37-66% of the variation among moths depending on adult diet, and this effect was substantial. Taken together, our results suggest that the bulk of variation in realized fecundity is generated in the larval stage, provided suitable oviposition substrate is available for the adults. This information will be important in understanding population dynamics of beet armyworm and to improving our ability to predict population outbreaks from sampling data.

In the current study, I investigated whether a similar effect resulted from male exposure to alpha -copaene, a naturally occurring compound found in many host plants, and two alpha -copaene-containing essential oils, angelica seed oil (Angelica archangelica L.) and ginger root oil, (Zingiber officinale Roscoe). For all three substances, mature males were exposed to 20 mu l of the attractant over a 6-h period and then held 2 d before testing. In field-cage trials, treated males (exposed to attractants) obtained significantly more matings than control males (no exposure) for all three substances. In an additional experiment with ginger root oil, treated males prevented from contacting the oil directly (i.e., exposed to the odor only) still exhibited a mating advantage over control males. Discussion centers on the influence of alpha -copaene-bearing plants on the mating system of C. capitata and the possibility of using attractants in prerelease exposure of males to increase the effectiveness of sterile insect release programs.

Bands were placed on the trees in late August, at three heights on the tree. One-third of the bands was collected in January to determine what taxa of spiders overwintered in the shelters. The remaining bands at each site were collected and replaced at weekly intervals between late August and early December to monitor phenology of movement into the shelters. More than 2,900 spiders in 10 families were recovered from the winter-collected set of bands. Spiders were collected from all three sampling heights in the trees. The majority of spiders were juveniles, although adults of some Salticidae [especially Pelegrina aeneola (Curtis) and Phanias sp.] were fairly common. The dominant families were Philodromidae (primarily Philodromus spp.) and Salticidae (primarily P. aeneola), comprising 66 and 28%, respectively, of the total specimens. In the weekly collections, >5,600 bands were sampled during the study producing >6,000 spiders represented by 12 families and 30 identified genera. Dominant taxa in the weekly collected bands included Philodromus cespitum (Walckenaer), P. aeneola, Xysticus spp. (Thomisidae), Sassacus papenhoei Peckham and Peckham (Salticidae), Phidippus spp. (Salticidae), and Anyphaena pacifica Banks (Anyphaenidae). Of these taxa, Xysticus spp., S. papenhoei, and A. pacifica were very uncommon in the winter-collected bands, and we infer from these results that these spiders used the bands as temporary refuges only, and overwintered elsewhere. Data obtained from the weekly collected bands suggested that Philodromus, spp., Dictyna spp., P. aeneola, and Cheiracanthium mildei L. Koch entered overwintering shelters during the interval between mid-October and mid- to late November. Pear and apple blocks at the same site were more similar in community composition than a common crop species at two different sites. More spiders were recovered from bands placed in the unmanaged and organically managed orchards than from apple and pear blocks that received insecticides during the growing season.

An evaluation of chemotaxonomic, morphological and physiological properties in the light of the molecular phylogeny data revealed that several species are misclassified. Saccharothrix aerocolonigenes NRRL B-3298(T) and Saccharothrix flava NRRL B-16131(T) constitute a lineage distinct from Saccharothrix and separate from Lentzea. The genus Lechevalieria gen. nov. is proposed for these species. Lechevalieria aerocolonigenes comb. nov. is the type species and S. flava is transferred as Lechevalieria flava comb. nov. Although Lentzea albidocapillata, the type species of the genus Lentzea, was transferred recently to the genus Saccharothrix, the revival of Lentzea is clearly supported by molecular phylogenetic and chemotaxonomic data. The description of the revived genus is emended to include galactose, mannose and traces of ribose as diagnostic whole-cell sugars and MK-9(H(4)) as the principal menaquinone and elimination of tuberculostearic acid as a diagnostic component in the fatty acid profile. Saccharothrix waywayandensis NRRL B-16159(T), S. aerocolonigenes NRRL B-1613 7 and 'Asiosporangium albidum' IFO 16102 are members of the amended genus Lentzea on the basis of phylogenetic and chemotaxonomic properties. S. waywayandensis is transferred to Lentzea as Lentzea waywayandensis comb. nov., while the new species Lentzea californiensis sp. nov. and Lentzea albida sp. nov. are described for S. aerocolonigenes NRRL B-16137 and 'A. albidum' IFO 16102, respectively. Nucleotide signatures in the 16S rDNA sequences are defined that are diagnostic for the genera Lechevalieria, Lentzea and Saccharothrix.

Many plants are affected by witches' broom disease, which is characterized by excessive axillary branching, abnormally small leaves, and deformed flowers, symptoms that are characteristic of diseases attributed to phytoplasmas. A Phytoplasma was detected in diseased Hibiscus by amplification of rRNA operon sequences by PCRs, and was characterized by RFLP and nucleotide sequence analyses of 16S rDNA. The collective RFLP patterns of amplified 16S rDNA differed from the patterns described previously for other phytoplasmas. On the basis of the RFLP patterns, the hibiscus witches' broom phytoplasma was classified in a new 16S rRNA RFLP group, designated group 16SrXV. A phylogenetic analysis of 16S rDNA sequences from this and other phytoplasmas identified the hibiscus witches' broom Phytoplasma as a member of a distinct subclade (designated subclade xiv) of the class Mollicutes. A phylogenetic tree constructed on the basis of 16S rRNA gene sequences was consistent with the hypothesis that there was divergent evolution of Hibiscus witches' broom Phytoplasma and its closest relatives (members of 16S rRNA RFLP group 16SrII) from a common ancestor. On the basis of unique properties of the DNA from Hibiscus witches' broom Phytoplasma, it is proposed that it represents a new taxon, namely 'Candidatus Phytoplasma brasiliense'.

To determine whether dormancy affects seed respiration, we compared CO sub(2)evolution from individual imbibed dormant and non-dormant seeds and from germinating seeds, using Fourier transform infrared photoacoustic spectroscopy. We found CO sub(2)evolution did not differ between dormant and non-dormant seeds, and that it accelerated with germination and growth. Our results are in agreement with other studies indicating that dormant seeds respire. We conclude that high respiration rates in dormant bitterbrush seeds can decrease seedling vigor, and we recommend bitterbrush be sown when soil temperatures are cool enough to prevent significant losses of respiratory substrate from imbibed dormant seeds.

The first strain, producing 2-keto-D-gluconate (2 KDG) from D-glucose via D-gluconate (DG), was classified as Flavimonas oryzihabitans. The second strain, that converts 2 KDG to 2,5 DKG, was identified as Pseudomonas cepacia. This approach presents a new possibility to produce ascorbic acid by microbial transformation, including the use of other, more convenient substrates.

To develop a polymerase chain reaction (PCR) assay specific for detection of the causal agent, Spiroplasma kunkelii, PCR primers were designed on the basis of unique regions of the nucleotide sequence of the S. kunkelii spiralin gene. DNA was amplified in PCRs containing template DNAs derived from laboratory strains of S. kunkelii and from naturally diseased corn plants collected in the field. No DNA amplification was observed in PCRs containing template DNAs derived from other Spiroplasma species tested or from healthy corn or corn infected by maize bushy stunt phytoplasma. The availability of a sensitive and specific PCR for detection and identification of S. kunkelii should facilitate studies of the ecology of this pathogen, as well as its influence in the incidence, spread, and severity of corn stunting diseases.

Strains of the bacterium isolated from the two plant hosts are very closely related, and the two diseases share sharpshooter insect vectors. In order to determine if citrus strains of X. fastidiosa could infect coffee and induce CLS disease, plant inoculations were performed. Plants of coffee, Coffea arabica 'Mundo Novo', grafted on Coffea canephora var. robusta 'Apuatao 2258' were mechanically inoculated with triply cloned strains of X. fastidiosa isolated from diseased coffee and citrus. Three months postinoculation, 5 of the 10 plants inoculated with CLS-X. fastidiosa and 1 of the 10 plants inoculated with CVC-X. fastidiosa gave positive enzyme-linked immunosorbent assay (ELISA) and/or polymerase chain reaction (PCR). Eight months postinoculation, another six plants inoculated with CVC-X. fastidiosa gave positive PCR results. The two X. fastidiosa strains were isolated from the inoculated plants and showed the same characteristics as the original clones by microscopy, ELISA, and PCR. None of the plants inoculated with sterile periwinkle wilt (PW) medium as controls gave positive reactions in diagnostic tests, and none developed disease symptoms. Six months postinoculation, seven plants inoculated with CLS-X. fastidiosa and eight inoculated with CVC-X. fastidiosa began to develop characteristic CLS symptoms, including apical and marginal leaf scorch, defoliation, and reductions of internode length, leaf size, and plant height, terminal clusters of small chlorotic and deformed leaves, and lateral shoot dieback. We have demonstrated that X. fastidiosa from citrus plants is pathogenic for coffee plants. This has important consequences for the management of CLS disease and has implications for the origin of citrus variegated chlorosis disease.

In the complex glaciated terrain of the northern Lake States, subsurface water movement can be substantial. On the Marcell experimental forest (MEF) in north-central Minnesota, ground water table elevations measured in observation wells in recharge areas were used to calculate rates of ground water recharge. In northern Minnesota winters, precipitation is stored on the surface as snow and ground water recharge ceases. Water table elevations in recharge areas decline over winter at calculable rates. Deviations from these rates during other times of the year are due to ground water recharge. On 10-50 ha watersheds on the MEF, ground water recharge varies among watersheds but constitutes about 40% of the total water yield. Annual ground water recharge amounts were found to vary linearly with precipitation. Even in high precipitation years, the infiltration capacity of the watersheds was not exceeded. Regression equations were developed relating yearly ground water recharge, stream flow, and total water yield, to seasonal precipitation amounts, summer and autumn precipitation during the previous year, and non-winter air temperature.

Theoretically, we derive the optimal forms of taxes which take account of heterogeneity (non-uniform taxes) and a tax which does not (a uniform tax). Empirically, we use a multi-factor, market-equilibrium simulation model to determine optimal tax rates and associated equity effects, particularly differences in landowner gains/losses across a heterogeneous region. When market prices are endogenous, second-best tax policies result in pecuniary externalities that affect existing environmental externalities. In particular, the pecuniary externalities amplify the effect of producer heterogeneity on determination of sub-regional differences in tax rates and returns to land, particularly for the uniform policy. With endogenous prices, the uniform tax rate is considerably higher than any of the non-uniform rates and, ironically, the non-uniform taxes result in less dispersion of landowner gains across sub-regions than the uniform tax.

To meet Clean Air standards, large amounts of S must not be emitted into the atmosphere, which means considerable amounts of flue gas desulfurization products (FGDs) are and will be produced. Beneficial uses of FGDs are continually being sought to reduce waste, decrease cost of disposal, and provide value-added products. Beneficial agricultural uses of FGDs include application as amendment to acidic soil to mitigate low pH problems (Al and Mn toxicities); provide plant nutrients (i.e. Ca, S, and Mg); improve soil physical properties (e.g. water infiltration and soil aggregation); help alleviate soil compaction and improve aggregate stability of sodic soils; and inactivate P under high P-soil conditions to reduce P runoff. Co-utilization of FGDs with organic materials (manures, composts, biosolids) should also provide many benefits when used on land. Constraints for use of FGDs on agricultural land could be both insufficient or excessive amounts of CaCO sub(3), CaO, and/or Ca(OH) sub(2) in raising soil pH insufficiently or too much; excessive Ca to cause imbalanced Mg, P, and K in soils/plants; Ca displacement of Al from soil exchange sites to induce Al toxicity in plants; high B to induce B toxicity in plants; excessive sulfite which is toxic to plants; and excessive amounts of undesirable trace elements (e.g. As, Cd, Cr, Ni, Pb, and Se) which could potentially contaminate water and pose toxicity to plants/animals/microorganisms. Most constraints should not impose problems for FGD use on land.

Two alternative strategies for reducing nutrient loads from cropland are to reduce fertilizer application rates and to filter nutrients coming off cropland with restored wetlands. These two approaches are evaluated in the Mississippi Basin, where nutrient loadings to the Gulf of Mexico have caused a large zone of hypoxic waters. Because of the easement and restoration costs of wetlands, a fertilizer standard was found to be more cost effective than restoring wetlands for achieving a water quality goal up to a particular level of total nitrogen loss reduction. Beyond this point, wetland restorations are more cost-effective.

This article tests the effect of development restrictions imposed by permanent easement sales on farmland sales prices, using Maryland data. We correct for selectivity bias due to the voluntary nature of these programs in estimating hedonic sales equations. Although preserved parcels' actual land values are lower, the effect of the restrictions is not statistically significant. These findings may encourage additional participation in preservation programs or justify reductions in the easement prices paid by agencies.

Taeniid tapeworms in Africa twice independently colonized hominids and the genus Homo prior to the origin of modern humans. Dietary and behavioural shifts, from herbivory to scavenging and carnivory, as early Homo entered the carnivore guild in the Pliocene/Pleistocene, were drivers for host switching by tapeworms to hominids from carnivores including hyaenids and felids. Parasitological data provide a unique means of elucidating the historical ecology, foraging behaviour and food habits of hominids during the diversification of Homo spp. JF - Proceedings - Royal Society of London, Biological Sciences AU - Hoberg, Eric P AU - Alkire, Nancy L AU - de Queiroz, Alan AU - Jones, Arlene Y1 - 2001/04/22/ PY - 2001 DA - 2001 Apr 22 SP - 781 EP - 787 PB - Royal Society, London VL - 268 IS - 1469 SN - 0962-8452, 0962-8452 KW - parasites KW - diet KW - Taeniidae KW - behavior KW - Homo KW - Platyhelminthes KW - paleoecology KW - Cenozoic KW - Theria KW - Invertebrata KW - Eutheria KW - Chordata KW - Quaternary KW - living taxa KW - predation KW - phylogeny KW - Mammalia KW - biologic evolution KW - Primates KW - Hominidae KW - Tertiary KW - Neogene KW - Pliocene KW - Pleistocene KW - Africa KW - Vertebrata KW - Taenia KW - cladistics KW - Tetrapoda KW - Cestoda KW - 08:General paleontology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1535200995?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Proceedings+-+Royal+Society+of+London%2C+Biological+Sciences&rft.atitle=Out+of+Africa%3B+origins+of+the+Taenia+tapeworms+in+humans&rft.au=Hoberg%2C+Eric+P%3BAlkire%2C+Nancy+L%3Bde+Queiroz%2C+Alan%3BJones%2C+Arlene&rft.aulast=Hoberg&rft.aufirst=Eric&rft.date=2001-04-22&rft.volume=268&rft.issue=1469&rft.spage=781&rft.isbn=&rft.btitle=&rft.title=Proceedings+-+Royal+Society+of+London%2C+Biological+Sciences&rft.issn=09628452&rft_id=info:doi/10.1098%2Frspb.2000.1579 L2 - http://rspb.royalsocietypublishing.org/ LA - English DB - GeoRef N1 - Copyright - GeoRef, Copyright 2014, American Geosciences Institute.

AN - 77053136; 11295152 AB - Free radicals and reactive oxygen species (ROS) which are generated continuously cause mutagenic alterations resulting in cancer, aging and abnormalities in the nervous system. Accumulating evidence indicates that Vitamin E, the most potent lipid peroxyl radical scavenger, may reduce free radical induced chromosomal damages through inhibition of free radical formation, and activation of endonuclease that can be triggered by intracellular oxidative stress, and by increasing the rate of removal of damaged DNA. Although some studies suggest a potential usefulness of Vitamin E in the prevention of mutagenic effects caused by genotoxic free radicals, other studies report no effects. Thus the data are not conclusive enough to be used as a basis to change the current recommended dietary allowances (RDA). Future research should address molecular mechanisms underlying the protective effects of Vitamin E and develop appropriate biologically relevant biomarkers of DNA damage to further help in determining the dietary levels of Vitamin E needed to protect the genetic pool from internally and externally induced DNA damages.

Franco) trees with a southern exposure were selected randomly to receive a water-stress, defoliation, or control treatment. All water-stressed branches were attacked by Scolytus unispinosus LeConte at 12-24 days after imposing the treatments, resulting in a significantly higher mean density of gallery holes (107 m super(-2)) than in the defoliated or control branches, which were not attacked. Needles and woody tissues from stressed branches, sampled after being attacked, contained significantly higher ethanol concentrations (ranging from 2.91 to 15.26 mu mol g super(-1) fresh weight) than tissue from defoliated or control branches (0.005-0.12 mu mol g super(-1) fresh weight). Ethanol concentrations did not differ between defoliated and control branches. The water content in woody tissues and needles of stressed branches was 40.9 and 28.1% of the amount in control branches, respectively, when sampled for ethanol analysis. Woody tissues in defoliated branches remained moist, with 91.3% of the water in controls. Drying needles from water-stressed branches also lost 18.3-33.7% of their total monoterpenes compared to needles on the controls. The mechanism for ethanol synthesis in water-stressed branches appears to be distinctly different from that of logs overwintering on the forest floor. Ethanol synthesis in stressed branches probably was initiated by cytoplasmic acidification as a result of damage to cellular membranes from drying and heating. The ethanol that accumulated in needles and woody tissues of stressed branches functioned as a primary host attractant for S. unispinosus at our Willamette Valley, Oregon, site.

Both myc- or hemagglutinin-tagged Fad2 and Fad3 localized to the same region of the endoplasmic reticulum (ER), as evidenced by their co-localization with the ER lumenal protein calreticulin. Results from differential permeabilization experiments revealed that the N-termini of both epitope-tagged Fad2 and Fad3 were exposed on the cytosolic side of ER membranes.

AN - 17889277; 5136080 AB - Few studies directly address the consequences of habitat fragmentation for communities of pollinating insects, particularly for the key pollinator group, bees (Hymenoptera: Apiformes). Bees typically live in habitats where nesting substrates and bloom are patchily distributed and spatially dissociated. Bee studies have all defined habitat fragments as remnant patches of floral hosts or forests, overlooking the nesting needs of bees. Several authors conclude that habitat fragmentation is broadly deleterious, but their own data show that some native species proliferate in sampled fragments. Other studies report greater densities and comparable diversities of native bees at flowers in some fragment size classes relative to undisrupted habitats, but find dramatic shifts in species composition. Insightful studies of habitat fragmentation and bees will consider fragmentation, alteration, and loss of nesting habitats, not just patches of forage plants, as well as the permeability of the surrounding matrix to interpatch movement. Inasmuch as the floral associations and nesting habits of bees are often attributes of species or subgenera, ecological interpretations hinge on authoritative identifications. Study designs must accommodate statistical problems associated with bee community samples, especially non-normal data and frequent zero values. The spatial scale of fragmentation must be appreciated: bees of medium body size can regularly fly 1-2 km from nest site to forage patch. Overall, evidence for prolonged persistence of substantial diversity and abundances of native bee communities in habitat fragments of modest size promises practical solutions for maintaining bee populations. Provided that reserve selection, design, and management can address the foraging and nesting needs of bees, networks of even small reserves may hold hope for sustaining considerable pollinator diversity and the ecological services pollinators provide.

Extensive losses in pollinator guilds and communities can disrupt ecosystem integrity, a circumstance that today forces most farmers to rely on honey bees for much fruit and seed production. Are North America's invertebrate pollinator faunas already widely diminished or currently threatened by human activities? How would we know, what are the spatiotemporal scales for detection, and which anthropogenic factors are responsible? Answers to these questions were considered by participants in a workshop sponsored by the National Center for Ecological Analysis and Synthesis in October of 1999, and these questions form the nucleus for the papers in this special issue. Several contributors critically interpret the evidence for declines of bee and fly pollinators, the pollination deficits that should ensue, and their economic costs. Spatiotemporal unruliness in pollinator numbers, particularly bees, is shown to hinder our current insights, highlighting the need for refined survey and sampling designs. At the same time, two remarkable studies clearly show the long-term persistence of members of complex bee communities. Other authors offer new perspectives on habitat fragmentation and global warming as drivers of pollinator declines. Bees and lepidopterans are contrasted in terms of their natural genetic variation and their consequent resilience in the face of population declines. Overall, many ecologists and conservation biologists have not fully appreciated the daunting challenges that accompany sampling designs, taxonomy, and the natural history of bees, flies, and other invertebrate pollinators, a circumstance that must be remedied if we are to reliably monitor invertebrate pollinator populations and respond to their declines with effective conservation measures.

Quick-Germ has the potential to increase the coproduct credits and profitability of the existing dry-grind fuel ethanol process, but the fermentability of the corn remaining after oil recovery has not been tested. Therefore, a series of pilot scale (50 L) fermentations was carefully controlled and monitored with unique methods for standard inoculation and automatic sampling. It was found that the concentration of suspended solids was significantly reduced in the Quick-Germ fermentations. When compared at the same concentration of fermentable sugars, the fermentation rate and yield were not statistically different from controls. When Quick-Germ was integrated into a state-of-the-art dry-grind fuel ethanol process, computer simulation and cost models indicated savings of approx 0.01 / L of ethanol ( 0.04/gal) with the Quick-Germ process. Additional savings associated with the lower suspended solids could not be quantified and were not included. However, the savings are sensitive to the price of corn oil.

AN - 77067041; 11308129 AB - Approximately 80 head of yearling cattle grazing on 680 acres exhibited signs of Leucaena leucocephala toxicosis, which was confirmed in 3 animals by detection of 3-hydroxy-4 (IH)-pyridone, the metabolite of the poisonous principle mimosine, in their urine. The animals had grazed leucaena almost exclusively due to lack of alternative forage resulting from drought conditions. Toxicosis from this otherwise high quality forage would likely not have occurred had animals consumed lower amounts of leucaena and could probably have been prevented, as it has been elsewhere, had the animals been colonized with Synergistes jonesii, a beneficial ruminal bacterium capable of degrading the toxic metabolites.

AN - 77056209; 11304752 AB - BTR-270, a gypsy moth (Lymantria dispar) brush border membrane molecule that binds Bacillus thuringiensis (Bt) Cry1A toxins with high affinity, was purified by preparative gel electrophoresis. Rabbit antibodies specific for the Bt toxin-binding molecule were raised. Attempts to label BTR-270 by protein-directed techniques were futile, but it was degraded by proteases with broad specificity indicating the presence of a peptide. Carbohydrate was detected by labeling with digoxigenin hydrazide following periodate oxidation. Mild alkaline hydrolysis destroyed toxin and antibody binding, suggesting O-linked glycans are involved in the activity. GC/MS composition analysis showed that the predominant sugars were galactose, glucose, and N-acetyl galactosamine with lesser amounts of N-acetyl glucosamine, glucuronic acid, xylose, and fucose. The carbohydrate moiety accounted for 73% of its total mass. Amino acid analysis showed a high content of aspartic/asparagine, threonine, and serine residues in the protein moiety. The purified glycoconjugate was not visualized using Coomassie or silver staining procedures, but stained "blue" using the cationic dye Stains-all. BTR-270 was labeled with biotin and used as a diagnostic probe for screening and identifying toxins that bind to the receptor. Toxin-binding kinetics obtained using a biosensor demonstrated that the receptor binds Cry1Aa and Cry1Ab toxins with high affinity, and displays a weaker affinity for Cry1Ac, in correlation with the toxicity of these toxins towards gypsy moth.

AN - 77045581; 11297278 AB - Four experiments were conducted using day-of-hatch, mixed-sex broiler chicks to evaluate the effects of aflatoxins and T-2 toxin on cecal volatile fatty acids (VFA) and the susceptibility to Salmonella colonization. All chicks in these experiments were challenged orally with 10(4) cfu of Salmonella typhimurium (ST) on Day 3. In Experiments 1 and 2, chicks were fed diets containing 0, 2.5, or 7.5 mg aflatoxins/kg of diet and were allowed to develop their microflora naturally. In Experiment 3, all chicks were orally gavaged on the day of hatch with a competitive exclusion (CE) culture (PREEMPT) and were fed diets containing 0, 2.5, or 7.5 mg T-2 toxin/kg. In Experiment 4, the chicks were fed diets containing 0, 7.5, or 15.0 mg T-2 toxin/kg and one-half of the chicks were orally gavaged on the day of hatch with the CE culture. In Experiments 1 and 2, with the exception of increased total VFA at 5 d in chicks fed the 7.5 mg T-2 aflatoxins/kg diet, there were no treatment effects on cecal propionic acid, total VFA, or incidence or severity of ST colonization. In Experiment 3, the only alteration in concentration of cecal propionic acid or total VFA was a significant reduction in total VFA at 5 d in chicks fed the 2.5 mg T-2 toxin/kg diet. No significant treatment differences were observed for numbers of Salmonella cecal culture-positive chicks or for numbers of ST in the cecal contents. In Experiment 4, with minor exceptions, the chicks treated with the CE culture had higher cecal concentrations of propionic acid and were less susceptible to Salmonella colonization than the non-CE-treated chicks. In the non-CE-treated chicks, T-2 toxin had no effect on any of the parameters, and 85 to 90% of the chicks were Salmonella cecal culture-positive. In the CE-treated chicks, there was a decrease in propionic acid concentration at 3 and 11 d and an increase in susceptibility to Salmonella colonization of the chicks fed the 15.0 mg T-2 toxin/kg diet. These results indicate that cecal concentrations of VFA can be affected by toxins, such as high concentrations of T-2 toxin, and that resistance to Salmonella colonization may be reduced. Further research is necessary to determine the biological significance of these changes.

AN - 77042420; 11298941 AB - The objective of this study was to determine if acetosyringone affected the expression of aflatoxin biosynthetic genes. Two genes, nor1 and ver1, representing genes whose products are involved in early and late steps in aflatoxin biosynthesis, were examined. Two GUS (beta-glucuronidase) reporter constructs, nor1:GUS (pGAP12) and ver1:GUS (pGAP13), were used to study the effect of acetosyringone on expression of aflatoxin biosynthetic (AF) genes, nor1 and ver1. The product of nor1 is involved in the formation of norsolorinic acid, the first stable intermediate in the aflatoxin pathway. The ver1 gene codes for the enzyme catalyzing the formation of demethylsterigmatocystin, an intermediate late in the AF pathway. GUS activities of these two reporter constructs were inhibited by 80% in the presence of 2 m mol l-1 acetosyringone. Aflatoxin production in a toxigenic strain 42-12 was also shown to be inhibited by acetosyringone to the same level. The levels of inhibition in aflatoxin production and gene transcription are congruous in these three strains. Recent studies have indicated that some phenolics act as signal molecules in plant microbial interactions. Concentration of acetosyringone is shown to increase about ten fold when certain metabolically active plant tissues are wounded. The knowledge gained can be applied to develop strategies in plant breeding programs. The compound may be useful for studying molecular mechanism of modulating aflatoxin biosynthesis.

AN - 70941565; 11417822 AB - Detecting infected laying flocks is a vital part of many efforts to control egg-associated transmission of Salmonella enteritidis to humans. The relationship between the development of a specific antibody response in infected hens and the deposition of S. enteritidis in eggs is important for establishing the epidemiologic relevance of serologic testing methods. In two trials, laying hens were infected with large oral doses of phage types 13a and 14b isolates of S. enteritidis. Approximately 38% of all infected hens produced at least one contaminated egg, at an overall incidence of 5.2%, between 3 and 23 days postinoculation. As determined by enzyme-linked immunosorbent assay with an S. enteritidis flagellar antigen, 91.7% of inoculated hens produced specific serum antibodies. Although hens with very high antibody titers were associated with a significantly elevated frequency of egg contamination, a consistently direct relationship was not evident between the magnitude of the antibody responses of individual hens and the frequency at which they laid contaminated eggs. Accordingly, although serologic tests can be valuable screening tools for preliminary detection of S. enteritidis infections in poultry, the magnitude of the antibody responses detected in individual hens may not predict the overall risk of egg contamination associated with particular laying flocks.

AN - 70836798; 11346958 AB - Aluminum tolerance was assessed in the moderately Al-tolerant wheat (Triticum aestivum L.) cultivar Chinese Spring and a set of ditelosomic lines derived from Chinese Spring. Three ditelosomic lines lacking chromosome arms 4DL, 5AS and 7AS, respectively, exhibited decreased Al tolerance relative to the euploid parent Chinese Spring based on reduced root growth in Al-containing solutions. The physiological basis of the reduced Al tolerance was investigated. Measurements by inductively coupled argon plasma mass spectroscopy of root apical Al accumulation demonstrated that two of these three lines had a decreased ability to exclude Al from the root apex, the site of Al phytotoxicity. As Al-induced malate exudation has been suggested to be an important physiological mechanism of Al tolerance in wheat, this parameter was quantified and malate exudation was shown to be smaller in all three deletion lines compared with Chinese Spring. These results suggest that the decreased Al tolerance in at least two of the three ditelosomic lines is due to the loss of different genes independently influencing a single Al-tolerance mechanism, rather than to the loss of genes encoding alternative Al-tolerance mechanisms.

AN - 70822435; 11321913 AB - The purpose of this research was to determine the efficiency of a polymer biocover for the abatement of H2S and NH3 emissions from an east-central Missouri swine lagoon with a total surface area of 7800 m2. The flux rate of NH3, H2S, and CH4 was monitored continuously from two adjacent, circular (d = 66 m) control and treatment plots using a nonintrusive, micrometeorological method during three independent sampling periods that ranged between 52 and 149 hr. Abatement rates were observed to undergo a temporal acclimation event in which NH3 abatement efficiency improved from 17 to 54% (p = < 0.0001 to 0.0005) and H2S abatement efficiency improved from 23 to 58% (p < 0.0001) over a 3-month period. The increase in abatement efficiency for NH3 and H2S over the sampling period was correlated with the development of a stable anaerobic floc layer on the bottom surface of the biocover that reduced mass transfer of NH3 and H2S across the surface. Analysis of methanogenesis activity showed that the biocover enhanced the rate of anaerobic digestion by 25% when compared with the control. The biocover-enhanced anaerobic digestion process was shown to represent an effective mechanism to counteract the accumulation of methanogenic substrates in the biocovered lagoon.

AN - 70822258; 11332855 AB - Maysin, a C-glycosylflavone in maize silk, has insecticidal activity against corn earworm, Helicoverpa zea (Boddie), larvae. Sweet corn, Zea mays L., is a vulnerable crop to ear-feeding insects and requires pesticide protection from ear damage. This study was conducted to identify maize chromosome regions associated with silk maysin concentration and eventually to transfer and develop high silk maysin sweet corn lines with marker-assisted selection (MAS). Using an F2 population derived from SC102 (high maysin dent corn) and B31857 (low maysin sh2 sweet corn), we detected two major quantitative trait loci (QTL). It was estimated that 25.6% of the silk maysin variance was associated with segregation in the genomic region of npi286 (flanking to p1) on chromosome 1S. We also demonstrated that a1 on chromosome 3L had major contribution to silk maysin (accounted for 15.7% of the variance). Locus a1 has a recessive gene action for high maysin with the presence of functional p1 allele. Markers umc66a (near c2) and umc105a on chromosome 9S also were detected in this analysis with minor contribution. A multiple-locus model, which included npi286, a1, csu3 (Bin 1.05), umc245 (Bin 7.05), agrr21 (Bin 8.09), umc105a, and the epistatic interactions npi286 x a1, a1 x agrr21, csu3 x umc245, and umc105a x umc245, accounted for 76.3% of the total silk maysin variance. Tester crosses showed that at the a1 locus, SC102 has functional A1 alleles and B31857 has homozygous recessive a1 alleles. Individuals of (SC102 x B31857) x B31857 were examined with MAS and plants with p1 allele from SC102 and homozygous a1 alleles from B31857 had consistent high silk maysin. Marker-assisted selection seems to be a suitable method to transfer silk maysin to sweet corn lines to reduce pesticide application.

AN - 70806516; 11332823 AB - The addition of a stilbene optical brightener, Tinopal LPW, at 1% concentration (wt:wt) significantly reduced the LC50 of the beet armyworm nuclear polyhedrosis virus (SeMNPV) from 2.9 PIB/mm2 to 0.02 PIB/mm2. Moreover, the LT50 of SeMNPV was reduced by 34% by the addition of Tinopal LPW. Seven other structurally related stilbene brighteners were also tested as viral enhancers. Five of these brighteners (Tinopal LPW, Blankophor BBH, Blankophor HRS, Blankophor P167, and Blankophor RKH) reduced LD50, whereas three brighteners (Blankophor BSU, Blankophor DML, and Blankophor LPG) had little effect. Among the active brighteners, LC50s were reduced by 10.5-fold (Blankophor P167), 52.4-fold (Blankophor RKH), 87.3-fold Tinopal LPW), 131-fold (Blankophor BBH), and >400-fold (Blankophor HRS). LT50s were also decreased by the addition of Blankophor BBH, Blankophor P167, and Blankophor RKH, but were increased by the addition of Blankophor BSU, Blankophor DMLO, and Blankophor LPG to SeMNPV suspensions.

AN - 70805868; 11332827 AB - Diatomaceous earth (DE) is a desiccant insecticide and most efficacious in low humidity. It acts on insect cuticle by absorbing lipids, and perhaps by cuticular abrasion. Beauveria bassiana (Balsamo) Vuillemin, an entomopathogenic fungus, is most efficacious in high humidity and has a complex interaction with cuticular lipids. Interaction between these materials may enhance insect control performance. Assays with stored-grain beetles were conducted with B. bassiana at rates of 11, 33, 100, and 300 mg of conidia per kilogram of grain with and without single rates of DE that killed 10% or less of the target beetles. The assays revealed synergism in effects on adult Rhyzopertha dominica (F.) and Oryzaephilus surinamensis (L.) at all doses. There was statistically significant synergism for adult Cryptolestes ferrugineus (Stephens) and larval R. dominica but at only one B. bassiana rate for each target. Both amorphous silicon dioxide, a sorptive dust, and diamond dust, an abrasive, showed synergistic interaction with B. bassiana on adult R. dominica. These results may provide a basis for a least-toxic approach to control of stored-product beetles and for efficacy-enhancing formulation of entomopathogenic fungi.

AN - 70800300; 11332825 AB - Imidacloprid and the entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin are both used to control the whitefly Bemisia argentifolii Bellows & Perring. We tested whether the two control strategies acted additively, synergistically, or antagonistically when combined for whitefly control. We found antagonism in that B. bassiana inhibited the effectiveness of imidacloprid. When B. bassiana was combined with imidacloprid, insect response was either less than or similar to (depending on B. bassiana rates) that when imidacloprid was used alone. Adding imidacloprid to B. bassiana treatments always increased mortality, but the increase was less than additive. Beauveria bassiana spore germination and colony formation were not inhibited by imidacloprid in vitro, and B. bassiana did not adsorb or degrade imidacloprid in a tank mix. We hypothesize that B. bassiana caused a behavioral response that reduced insect feeding and uptake of imidacloprid.

AN - 70776985; 11325186 AB - Heat stress is a major problem in transporting stocker calves with symptoms of fescue toxicosis. Removing calves from tall fescue pastures and offering diets devoid of endophyte-infected tall fescue could reduce the severity of toxicosis and precondition calves for transport to the feedlot. In the present experiment, a pasture phase was used to condition yearling steers to grazing tall fescue and induce symptoms of fescue toxicosis, and a pen phase followed to determine effects of implanting at the start of grazing and protein supplementation (hay only vs hay plus supplement) on short-term changes in rectal temperature and serum prolactin concentration. Neither implant status nor protein supplementation affected (P > 0.10) white blood cell count or rectal temperature. White blood cell counts at the conclusion of the pasture phase averaged 8,778 cells/microL and were within a range indicating no immunological response. Changes in rectal temperature and serum prolactin concentration during the pen phase were not influenced (P > 0.10) by implanting or supplementation. Initial rectal temperatures for the pen phase were high (39.9 degrees C) but declined linearly (P < 0.001) over the first 106 h and were below a normal temperature (39.2 degrees C) by 82 h following removal from tall fescue pastures. Serum prolactin gradually increased (P < 0.001) to a peak by 82 h and stabilized thereafter. Results indicate that neither supplemental protein nor an estrogenic implant influenced recovery indices of fescue toxicosis, whereas removing calves from tall fescue pastures and excluding dietary tall fescue for 3 to 4 d may alleviate symptoms of fescue toxicosis.

The virus is transmitted by the fecal-oral route with fecally contaminated drinking water being the usual vehicle. Hepatitis resulting from HEV infection is a moderately severe jaundice that is self-limiting in most patients. Young adults, 15 to 30 years of age, are the main targets of infection, and the overall death rate is 0.5 to 3.0%. However, the death rate during pregnancy approaches 15 to 25%. Death of the mother and fetus, abortion, premature delivery, or death of a live-born baby soon after birth are common complications of hepatitis E infection during pregnancy. Hepatitis E virus is found in both wild and domestic animals; thus, HEV is a zoonotic virus. The viruses isolated from swine in the United States or Taiwan are closely related to human HEV found in those areas. The close genetic relationship of the swine and human virus suggests that swine may be a reservoir of HEV. In areas where swine are raised, swine manure could be a source of HEV contamination of irrigation water or coastal waters with concomitant contamination of produce or shellfish. Increasing globalization of food markets by industrialized countries has the potential of introducing HEV into new areas of the world. The purpose of this review is to cover certain aspects of hepatitis E including the causative agent, the disease, diagnosis, viral detection, viral transmission, epidemiology, populations targeted by HEV, and the role of animals as potential vectors of the virus.

Whether the same is true of root growth and morphology, however, remains to be evaluated. We investigated interactive effects of CO sub(2) and soil water on root growth and morphology of two C sub(4) grasses. Seedlings of the dominant C sub(4) grasses from tallgrass prairie, Schizachyrium scoparium and Andropogon gerardii, were grown for 8 weeks in an elongated, controlled environment chamber at CO sub(2) concentrations of 368 (ambient) and 203 (subambient) mol mol super(-1). Seedlings were maintained at either high (ca. 90%) or low (ca. 50%) soil relative water holding capacity (RWC). Both root and shoot systems of C sub(4) grass seedlings responded similarly to CO sub(2) enrichment irrespective of whether soil water was limiting or abundant. Root growth was affected primarily by increased RWC (40-51% increases) and secondarily by higher CO sub(2) (15-27% increases). The relative distribution of root surface area, number of root tips and length and volume of roots were significantly affected by CO sub(2) enrichment with proportional increases of 55-61%, 39-52%, 50-55% and 53-58%, respectively, occurring in very fine (0-0.3 mm) roots. The indirect effect of CO sub(2) enrichment on conservation of soil water in grasslands may be as important as direct photosynthetic response effects in the CO sub(2)-induced enhancement of whole-plant growth in C sub(4) grasses.

We examined trade-offs between seedling fitness and dispersal ability by asking: does greater achene mass reduce dispersal ability, and is this potential disadvantage to large achenes compensated for by increased pappus investment? Does smaller achene mass reduce seedling fitness, and is this potential disadvantage to small achenes compensated for by increased relative growth rate (RGR)? Dispersal ability was measured as fall rate in still air, while seedling fitness was measured as dry mass at two ages for 21 populations belonging to nine subspecies. Fall rate was positively correlated with achene plume loading super(-1/2), but because of variation in pappus investment and geometry, both plume loading super(-1/2) and fall rate were only weakly positively correlated with achene mass. Relative pappus investment did not show a consistent increase with achene mass. Seedling dry mass was strongly positively correlated with achene mass for 2-week-old seedlings grown without added nutrients. This correlation was significant but weak with added nutrients at 2 weeks, and by 4 weeks it was no longer significant. Seedling RGR was strongly negatively correlated with achene mass. Achene mass variation was related to both seedling fitness and dispersal ability, but compensation was evident mainly as faster RGR in populations with small achenes.

AN - 18245849; 5309042 AB - Six open-top chambers were installed on the shortgrass steppe in north-eastern Colorado, USA from late March until mid-October in 1997 and 1998 to evaluate how this grassland will be affected by rising atmospheric CO sub(2). Three chambers were maintained at current CO sub(2) concentration (ambient treatment), three at twice ambient CO sub(2), or approximately 720 mu mol mol super(-1) (elevated treatment), and three nonchambered plots served as controls. Above-ground phytomass was measured in summer and autumn during each growing season, soil water was monitored weekly, and leaf photosynthesis, conductance and water potential were measured periodically on important C sub(3) and C sub(4) grasses. Mid-season and seasonal above-ground productivity were enhanced from 26 to 47% at elevated CO sub(2), with no differences in the relative responses of C sub(3)/C sub(4) grasses or forbs. Annual above-ground phytomass accrual was greater on plots which were defoliated once in mid-summer compared to plots which were not defoliated during the growing season, but there was no interactive effect of defoliation and CO sub(2) on growth. Leaf photosynthesis was often greater in Pascopyrum smithii (C sub(3)) and Bouteloua gracilis (C sub(4)) plants in the elevated chambers, due in large part to higher soil water contents and leaf water potentials. Persistent downward photosynthetic acclimation in P. smithii leaves prevented large photosynthetic enhancement for elevated CO sub(2)-grown plants. Shoot N concentrations tended to be lower in grasses under elevated CO sub(2), but only Stipa comata (C sub(3)) plants exhibited significant reductions in N under elevated compared to ambient CO sub(2) chambers. Despite chamber warming of 2.6 degree C and apparent drier chamber conditions compared to unchambered controls, above-ground production in all chambers was always greater than in unchambered plots. Collectively, these results suggest increased productivity of the shortgrass steppe in future warmer, CO sub(2) enriched environments.

AN - 18244992; 5309034 AB - Old forests are important carbon pools, but are thought to be insignificant as current atmospheric carbon sinks. This perception is based on the assumption that changes in productivity with age in complex, multiaged, multispecies natural forests can be modelled simply as scaled-up versions of individual trees or even-aged stands. This assumption was tested by measuring the net primary productivity (NPP) of natural subalpine forests in the Northern Rocky Mountains, where NPP is from 50% to 100% higher than predicted by a model of an even-age forest composed of a single species. If process-based terrestrial carbon models underestimate NPP by 50% in just one quarter of the temperate coniferous forests throughout the world, then global NPP is being underestimated by 145 Tg of carbon annually. This is equivalent to 4.3-7.6% of the missing atmospheric carbon sink. These results emphasize the need to account for multiple-aged, species-diverse, mature forests in models of terrestrial carbon dynamics to approximate the global carbon budget.

AN - 18244464; 5307678 AB - Genetic polymorphisms of flowering plants can influence pollinator foraging but it is not known whether heritable foraging polymorphisms of pollinators influence their pollination efficacies. Honey bees Apis mellifera L. visit cranberry flowers for nectar but rarely for pollen when alternative preferred flowers grow nearby. Cranberry flowers visited once by pollen-foraging honey bees received four-fold more stigmatic pollen than flowers visited by mere nectar-foragers (excluding nectar thieves). Manual greenhouse pollinations with fixed numbers of pollen tetrads (0, 2, 4, 8, 16, 32) achieved maximal fruit set with just eight pollen tetrads. Pollen-foraging honey bees yielded a calculated 63% more berries than equal numbers of non-thieving nectar-foragers, even though both classes of forager made stigmatic contact. Colonies headed by queens of a pollen-hoarding genotype fielded significantly more pollen-foraging trips than standard commercial genotypes, as did hives fitted with permanently engaged pollen traps or colonies containing more larvae. Pollen-hoarding colonies together brought back twice as many cranberry pollen loads as control colonies, which was marginally significant despite marked daily variation in the proportion of collected pollen that was cranberry. Caloric supplementation of matched, paired colonies failed to enhance pollen foraging despite the meagre nectar yields of individual cranberry flowers. Heritable behavioural polymorphisms of the honey bee, such as pollen-hoarding, can enhance fruit and seed set by a floral host (e. g. cranberry), but only if more preferred pollen hosts are absent or rare. Otherwise, honey bees' broad polylecty, flight range, and daily idiosyncrasies in floral fidelity will obscure specific pollen-foraging differences at a given floral host, even among paired colonies in a seemingly uniform agricultural setting.

Tritium and bromide were used as tracers for water flow and atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) was used as a probe chemical representing neutral organic compounds. Atrazine sorption isotherms were linear for all soils, and atrazine transport through water-saturated soil columns during steady water flow exhibited chemical non-equilibrium for Perrine and Krome soils columns. Apart from non-equilibrium chemical sorption, Chekika soil columns also had an added effect of mobile and immobile water zones that induced physical non-equilibrium during water movement. Simulation of leaching data revealed that the Convective-Dispersive Equilibrium (CDE) model could describe tracer breakthrough curves (BTCs) for Perrine and Krome soils, and the Two Site Non-Equilibrium (TSNE) model described atrazine BTCs. However, tracer BTCs from Chekika soil were described by the Two Region Non-Equilibrium (TRNE) model.

Of the substrates tested, maltose as a sole carbon source promoted maximal growth by S. halstedii while mannitol promoted maximal geosmin production, and galactose yielded the highest G/B values. Fish-food pellets and galactose were poor substrates for growth. Increasing phosphorus concentrations enhanced geosmin production and G/B values. Of the seven micronutrients tested, zinc, iron, and copper had the most profound effects on biomass and geosmin production. Increasing zinc concentrations promoted biomass production while inhibiting geosmin production and G/B values; increasing concentrations of copper and iron inhibited biomass and geosmin production. Increased copper concentrations had the greatest effect in preventing growth and geosmin production by S. halstedii.

Common finishing treatments of stainless steel surfaces used for components of poultry processign equipment were tested for resistance to bacterial attachment. Surface characteristics were evaluated to determine factors important for resistance. Disks of stainless steel were steel-ball burnished, glass-beaded, electropolished, acid-dipped, sandblasted, or left untreated. After treatment, the disks were incubated with bacteria from chicken carcass rinses. Bacterial growth during surface exposure was monitored by spectrophotometry, and bacterial counts were measured by scanning electron microscopy (SEM). The morphology of the surfaces was analyzed by atomic force microscopy (AFM), using disks from each of the treatments in the SEM studies. Changes in root mean square (RMS) roughness, center line average, bearing ratio/area, and other measurements corresponded to changes in bacterial contamination. Electropolished stainless steel showed fewer bacteria and biofilm formations than the other surfaces. The elemental composition of the surface was not changed by electropolishing. This article is the first to show that AFM is a rapid method for predicting the potential resistance of a surface to bacterial contamination. These results will aid manufacturers and processors in comparing and selecting finishes that are cost-effective and resistant to contamination.

Information pertaining to inheritance of physiological resistance, as detected by the greenhouse straw test, and its relationship with field resistance is lacking. The objectives of this study were to compare physiological resistance as detected by two separate straw tests with field resistance, evaluate heritability of physiological resistance, and to characterize the disease reaction of G 122 by quantitative trait locus (QTL) analysis. This was done in a recombinant inbred population (A 55/G 122) consisting of 67 F sub(8)-derived lines. The greenhouse tests with five and six replications, respectively, and the field test with three replications were conducted in randomized complete block designs. Moderate heritability for disease reaction (scored from 1 = no symptoms to 9 = severe disease) was observed across the straw tests (0.65) and in the field (0.78). Inheritance of disease reaction was further investigated with a framework linkage map composed of 74 markers. Interval mapping detected a QTL on linkage group B7 near the phaseolin seed protein (Phs) locus that explained 38% of the phenotypic variation for disease score across the straw tests. The same B7 QTL (26%), and an additional QTL (18%) on B1 near the fin gene for determinate growth habit, conditioned field resistance. A QTL (34%) for canopy porosity, a measure of potential disease avoidance, also mapped to the fin locus. Results confirmed that physiological resistance as detected by the straw test was an integral component of field resistance, and that both physiological and avoidance mechanisms contributed to field resistance in the A 55/G 122 population. The landrace G 122 clearly provides breeders with a heritable source of physiological resistance to combat white mold disease.

The potential for organic compounds to be transformed in groundwater has been measured using in situ methods, which avoid problems of attempting to duplicate aquifer conditions in the laboratory. In situ assessments of transformation rates have been accomplished using transport studies and in situ microcosms (ISMs); a review of these methods is given here. In transport studies, organic solutes are injected into an aquifer and the concentrations are monitored as they are transported downgradient. The change in mass of a solute is determined by the area contained under the breakthrough curve (plot of concentration versus time). ISMs isolate a portion of the aquifer from advective flow and act as in situ batch reactors. Experiments using ISMs involve removing water from the ISM, amending it with the solutes of interest, re-injecting the amended water, and monitoring the solute concentrations with time. In both transport and ISM studies, the loss of organic solutes from solution does not allow a distinction to be made between sorptive, abiotic and biotic transformation losses. Biological activity can be chemically suppressed in ISMs and the results from those experiments used to indicate sorption and abiotic loss. Transformation products may be monitored to provide additional information on transformation mechanisms and rates.

We evaluated five types of drip irrigation tubing installed at a depth of 0.4 m with lateral spacings of 1.6 and 2 m on 2.4 ha plots of both cotton and tomato. Approximately 40% of the cotton water requirement and 10% of the tomato water requirement were obtained from shallow (<2 m) saline (5 dS/m) ground water. Yields of the drip-irrigated cotton improved during the 3-year study, while that of the furrow-irrigated cotton remained constant. Tomato yields were greater under drip than under furrow in both the years in which tomatoes were grown. Salt accumulation in the soil profile was managed through rainfall and pre-plant irrigation. Both drip tape and hard hose drip tubing are suitable for use in our subsurface drip system. Maximum shallow ground water use for cotton was obtained when the crop was irrigated only after a leaf water potential (LWP) of -1.4 MPa was reached. Drip irrigation was controlled automatically with a maximum application frequency of twice daily. Furrow irrigation was controlled by the calendar.

Resurveys were made on 18 stream reaches. Physical attributes of stream channels were measured and flood responses were assessed across a range of stream types and land system units. Changes in cross-sectional area, width and depth were measured. Lateral migration was measured. Aggradation and degradation of thalweg depth were surveyed. There was high correlation between geomorphologic channel characteristics and channel response. Degree of entrenchment and channel slope were highly correlated with increases in channel depth and channel scour. Slightly entrenched channels had higher lateral migration rates. A hierarchical framework for ecological stratification offered geomorphic explanation for channel features that correlate with channel response to extreme flood events.

Similarly, goals for water yield and quality significantly influence the acceptability of various silvicultural practices. Developed through a process of consulting experts in various subspecialties of natural resource management, the NED super(1) decision support software is designed to provide a structure for project-level analysis of management alternatives based on identified goals. Using this software, one can analyze forest conditions in the northeastern United States with respect to water, wildlife, timber production, visual quality, and general ecological goals. Water quantity goals include increasing water flow, maintaining a minimum flow, and limiting peak flow. Water quality goals include intensive watercourse protection, wetlands protection, riparian area management, cold-water fish habitat, and warm-water fish habitat. In all cases, a minimum goal of obeying the law by following statutory best management practices (BMPs) is implied, whether or not one selects another water goal. Given a set of goals, a user of the NED system can analyze which goals are met under alternative silvicultural prescriptions or other activities and resolve which goals may or may not be compatible with each other.

The first year after cutting, streamflow increased 26 cm or 28% above the flow expected if the forest had not been cut. In subsequent years, discharge increases declined at a rate of 5-7 cm per year until the fifth year when changes in flow returned to baseline values. Later in forest succession, between ages 15 and 18 years, both significant increases and decreases in annual water yield were observed; these discharge dynamics are discussed in relation to vegetation regrowth dynamics. Flow responses predicted from an empirical regional scale model were within 17% of experimental values during the first 4 years of regrowth. Intra-annual analysis showed that proportionally larger increases (48%) in flow occurred in the low flow months of August-October.

Objectives were to evaluate the forage yield of 10 tall fescue (Festuca arundinacea Schreb.) strains and cultivars across five irrigation levels and to elucidate the effects of the endophytic fungus Neotyphodium coenophialum (Morgan-Jones & Gems) Glenn, Bacon & Hanlin on productivity and trends. A line-source irrigation system was used in a 2-yr study. Significant differences were detected among the tall fescue entries for dry matter yield (DMY), and differences were relatively consistent across water levels (WL) as indicated by the nonsignificant cultivar x WL interaction and significant correlations among WL. Trends in DMY across WL were largely curvilinear, however, linear trends were much more predominant during the late summer and fall. Stability parameters, based on regression of cultivar x WL x year means on their respective WL x year means, differed among cultivars in analyses including all harvests but were relatively uniform (b approximately 1.0) for most cultivars later in the season. Differences in DMY between `Ky 31' tall fescue infected with the Neotyphodium endophyte and its endophyte-free counterpart confirms earlier reports of the positive effect of this fungal organism on forage yield in tall fescue, particularly in water-limited environments. Seasonal distribution of yield was primarily determined by water availability during the late summer and fall. The relative consistency in DMY of the cultivars across WL indicates that annual yield averaged across levels of water stress would be a logical criterion for selection of germplasm for irrigated pastures in the Intermountain Region.

The choice of species and their water requirements are critical factors for providing a stable source of forage throughout the grazing season. A line-source irrigation system was used from 1995 to 1998 to evaluate dry matter (DM) production and seasonal forage distribution of nine orchardgrass (Dactylis glomerata L.) and perennial ryegrass (Lolium perenne L.) hybrid cultivars along with check cultivars of meadow brome (Bromus riparius Rehm.) and smooth brome (B. inermis Leyss.), tall fescue (Festuca arundinacea Schreb.), and quackgrass [Elytrigia repens (L.) Nevski] x bluebunch wheatgrass [Pseudoroegneria spicata (Pursh) A. Love] hybrids (RS) under five irrigation levels ranging from 41 to 91 cm per year. Mean DM production rankings across water levels combined over years were tall fescue > orchardgrass > meadow brome > RS-hybrid > smooth brome > perennial ryegrass-hybrids. The DM production response across water levels was largely linear with a minor but significant quadratic component at lower water rates. Tall fescue was most responsive (i.e., produced more DM production) to increased irrigation rates. At lower water levels, meadow brome outyielded orchardgrass. However, when water was not limited, orchardgrass outyielded meadow brome. The RS hybrid and smooth brome had relatively low DM production at both low and high water levels. All species produced significantly (P<0.01) more DM than perennial ryegrass at lower water levels. Under limited irrigation, tall fescue and meadow brome will produce more DM.

Christmas tree plantation in Indiana (1992-1994) and a plantation in Michigan (1994). In general, adults feed inside shoots during summer, then move to overwintering sites at the base of trees in autumn. In early autumn, adults were most often found in shoot-feeding tunnels that were still surrounded by green needles, whereas few were in tunnels surrounded by yellow or brown needles. For all years and sites combined, the range in the percentage of recently tunneled shoots that contained live T. piniperda adults decreased from 89 to 96% in mid-October, to 15-66% in early November, to 2-10% in mid-November, and to 0-2% by late November to early December. In each year, the first subfreezing temperatures in autumn occurred in October, before most adults left the shoots. Of 1,285 T. piniperda-tunneled shoots, one to seven tunnels (mean = 1.6) and zero to three adults were found per infested shoot. Of these 1,285 attacked shoots, 55% of the shoots had one tunnel, 33% had two, 9% had three, 3% had four, and <1% had five to seven tunnels each. When two or more tunnels occurred in a single shoot, adults were most commonly found in the innermost (most basal) tunnel. For the 2,070 tunnels found in the 1,285 shoots, average shoot thickness at the tunnel entrance was 6.0 mm, average distance from the tunnel entrance to the shoot tip was 6.3 cm, and average tunnel length was 2.3 cm. Four Scotch pine Christmas trees were dissected in January 1993. Eighty percent of the tunneled shoots were in the upper quarter of the tree crown and 98% were in the upper half. For the four trees inspected in January, one live adult was found in a shoot and 85 adults were found in the outer bark along the lower trunk from 1 cm below the soil line to 19 cm above the soil line. No overwintering adults were found outside the trunk in the duff or soil near the base of each test tree. Implications of these results are discussed in terms of surveying, timing the cutting of Christmas trees, and cutting height for Christmas trees.

All but one of the bacteria species were gram-negative bacteria. Bacterial isolates from dead termites were primarily Serratia marcescens Bizio that caused septicemia in C. formosanus and also appeared to contain proteolytic enzymes. Multiple strains of S. marcescens were isolated. Six of the eight strains of S. marcescens were red, probably not pathogenic in humans, and candidates as biological control agents for C. formosanus. Bacteria isolated from termite substrata included Corynebacterium urealyticum Pitcher, Acinetobacter calcoacet/baumannii/Gen2 (Beijerinck), S. marcescens, and Enterobacter gergoviae Brenner. Some of these bacteria are potential human pathogens. Forced exposure bioassays demonstrated that the T8 strain of S. marcescens killed 100% of C. formosanus by day 19.

The boundaries among landscape elements filter some organisms attempting to cross them, resulting in differing communities within the landscape elements. Ground beetles are numerous and generally disperse by walking. These qualities make them excellent organisms for the study of boundary dynamics. Our goal was to determine if natural habitats adjacent to wheat fields affected the species composition of ground beetles within the wheat fields. We captured ground beetles from autumn through spring 1996-1997 at two sites using directional pitfall traps placed in wheat fields and adjacent grasslands and riparian zones. Ground beetle abundance reached two peaks, one in autumn and the other in spring. Species composition was most strongly related to these seasons. Axis 1 of a canonical correspondence analysis separated spring active beetles from autumn active beetles. Axis 2 separated winter active beetles. With the effects of season and sites removed, axes 1 and 2 of a partial canonical correspondence analysis separated beetles with respect to habitat. Axis 1 separated beetles into wheat and natural habitat assemblages. Axis 2 further distinguished assemblages in wheat fields as those adjacent to grasslands and those adjacent to riparian habitats. Axis 2 also separated grassland, grassland edge, and riparian edge assemblages from riparian assemblages. Net dispersal of beetles across the boundaries showed no consistent pattern during autumn, winter, or spring. However, mark-recapture studies showed that several species routinely cross boundaries, which resulted in different community structures and an increase in abundance of beetles in the wheat interiors during spring.

The shortest times to initiation of wing fanning and flight occurred at 0.1 lux, the lowest light intensity evaluated. A gradual decrease in light intensity, compared with an instantaneous decrease, prolonged time to flight. The highest percentage of female flight was observed at 0.1 lux. A higher percentage of females initiated flight when exposed to lower light intensities after the onset of normal scotophase rather than before scotophase. Virgin females were less likely to fly than mated females. Females fanned their wings longer at lower temperatures and when they were capable of only a gliding flight. Females that were flight-tested the same day they emerged tended to take longer to initiate flight than those 1-2 d old. At 0.1 lux, the majority of the Asian females, less than 2% of the F sub(1) hybrid females, and none of the North American females exhibited strong, directed flight. Over half of the F sub(1) hybrids glided for a few meters while flapping their wings, whereas none of the North American females exhibited even this level of flight. Thus, female flight capability will be reduced when flighted and nonflighted forms initially hybridize.

Experiment 1 was a multiple-choice test designed to test relative preferences among 24 wood species commercially available in New Orleans, LA. Experiment 2 was a similar study designed to test relative preferences among 21 wood species shown or reported to be unpalatable to the Formosan subterranean termite. Experiment 3 was a no-choice test to examine the feeding deterrence of the 10 least preferred wood species. Preference was determined by consumption rates. Birch (Betula alleghaniensis Britton), red gum (Liquidambar styraciflua L.), Parana pine [Araucaria angustifolia (Bert.)], sugar maple (Acer saccharum Marsh.), pecan (Carya illinoensis Wangenh.), and northern red oak (Quercus rubra L.) were the most preferred species by C. formosanus in order of consumption rate. All of these species were significantly more preferred than southern yellow pine (Pinus taeda L.), widely used for monitoring. Sinker cypress [ = old growth bald cypress, Taxodium distichum (L.)], western red cedar (Thuja plicata Donn), Alaskan yellow cedar (Chamaecyparis nootkatensis D.

The objectives of this study were to determine the presence of large carnivores and to obtain information on their winter diets. Surveys were conducted in four major river drainages using sign (presence of scrapes, scats, tracks) transects. Scats were collected for general analysis of food items. Presence of snow leopard (Uncia uncia Schreber) was confirmed in the Pamir, Braldu, and Batura drainages. Presence of wolf (Canis lupis chanco Gray) was confirmed in the Pamir and Braldu drainages. Fox (Vulpes vulpes L.) occurred in the Batura, Shimshal, Pamir, and Braldu drainages. Scats of snow leopard and wolf mainly contained ungulates, small mammals, and snowcock (Tetraogallus himalayensis G.R. Gray). Fox scats contained mostly hawthorn (Crataegus L. spp.) fruits and small mammals.

Franco, forests. Within-stand distribution of mortality was examined in affected stands using geostatistical techniques. A 10 x 10 m grid was established in two 4-ha study sites. Live and beetle-killed host basal area was measured at each node. In a 16-ha stand, a variable-resolution grid was established and the same information collected. The relationship between Douglas-fir basal area and Douglas-fir basal area killed was examined using non-spatially explicit and spatially explicit linear regression models. A positive linear relationship was observed between the variables. Significant spatially explicit models suggest that the relationship is also true at fine scales. Relative variograms were constructed for Douglas-fir basal area before and after the Douglas-fir beetle outbreaks. For the 4-ha sites, increased spatial dependency in the distribution of Douglas-fir basal area was observed as a result of the Douglas-fir beetle outbreak. For the 16-ha site, kriging was used to estimate live Douglas-fir basal area before and after the outbreak to a 10-m resolution and the stand rated for potential mortality illustrating the potential applicability of geostatistical techniques to rating a stand for potential mortality. Cross-validation analysis indicated that although the potential exists for large estimation errors, the majority of the estimates were within acceptable ranges. The study suggests that geostatistical approaches may be suitable to extend our understanding bark beetle ecology and improving the application of extent of mortality models.

Eicosanoids are C20 polyunsaturated acids that are of widespread biochemical importance, including their role in protecting insects from bacterial infection. In laboratory experiments, the eicosanoid biosynthesis inhibitors dexamethasone, ibuprofen, and ibuprofen sodium salt were each provided along with a red-pigmented isolate of Serratia marcescens Bizio, a bacterial pathogen, to the Formosan subterranean termite, Coptotermes formosanus Shiraki, by means of treated filter paper. The increased mortality that resulted with dexamethasone and ibuprofen supported, but alone was insufficient to prove, the hypothesis that the termites' immune systems were suppressed by these compounds, making the insects more vulnerable to infection by S. marcescens. This effect on mortality was noted only at 3.4 x 10 super(10) colony-forming units per milliliter, a high treatment level. A significant amount of the infection and subsequent mortality may have resulted from direct contact with the bacterium and the remainder from its ingestion. Water-soluble ibuprofen sodium salt demonstrated a protective effect that was unexpected in light of the increased termite mortality observed with the relatively water insoluble, free acid form.

Exogenous treatment of cotton cv. Deltapine 5415 plants with MeJA induced the emission of the same volatile compounds as observed for herbivore-damaged plants. Cotton plants treated with MeJA emitted elevated levels of the terpenes (E)- beta -ocimene, linalool, (3E)-4,8-dimethyl-1,3,7-nonatriene, (E,E)- alpha -farnesene, (E)- beta -farnesene, and (E,E)-4,8,12-trimethyl-1,3,7,11-tridecatetraene compared to untreated controls. Other induced components included (Z)-3-hexenyl acetate, methyl salicylate, and indole. Methyl jasmonate treatment did not cause the release of any of the stored terpenes such as alpha -pinene, beta -pinene, alpha -humulene, and (E)- beta -caryophyllene. In contrast, these compounds were emitted in relatively large amounts from cotton due to physical disruption of glands by the herbivores. The timing of volatile release from plants treated with MeJA or herbivores followed a diurnal pattern, with maximal volatile release during the middle of the photoperiod. Similar to herbivore-treated plants, MeJA treatment led to the systemic induction of (Z)-3-hexenyl acetate, (E)- beta -ocimene, linalool, (3E)-4,8-dimethyl-1,3,7-nonatriene, (E,E)- alpha -farnesene, (E)- beta -farnesene, and (E,E)-4,8,12-trimethyl-1,3,7,11- tridecatetraene. Our results indicate that treatment of cotton with MeJA can directly and systemically induce the emission of volatiles that may serve as odor cues in the host-search behavior of natural enemies.

The residual effects of the treatments were determined over a 3-wk period. The addition of Helicoverpa armigera granulosis virus at a 1:100 dilution to Gypchek resulted in an approximate 10-fold increase in observed mortality, while the addition of Blankophor BBH at 1% resulted in an approximate 100-fold increase in observed mortality. The addition of Helicoverpa armigera granulosis virus at a 1:1000 dilution resulted in no consistent increase in recorded mortality, and the 1:100 granulosis virus dilution applied alone was inactive against gypsy moth.

Traps were baited with two release rates of ethanol (4.5 or 41.4 mg/hr) and three release rates of 4AA (0, 0.6, or 4.3 mg/hr) in a 2 x 3 factorial design. All traps also released a 1:1 mixture of alpha -and beta -pinene at 11.4 mg/hr. Of 13,396 scolytids caught, Dendroctonus valens made up 60%, Hylurgops spp. 18.5%, Ips spp. 16%, Hylastes spp. 1.8%, Ganthotrichus retusus 0.9%, and bark beetle predators another 2.8%. Increasing the release rate of ethanol in the absence of 4AA increased the number of most scolytid species caught by 1.5-3.7 times, confirming its role as an attractant, Ips latidens, Temnochila chlorodia, and clerid predators were exceptions and did not show a response to higher ethanol release rates. Release of 4AA at the lowest rate inhibited attraction of most scolytids, with a significant reduction in G. retusus, Hylastes macer, and Hylurgops porosus when compared to traps without 4AA. A high release rate of 4AA further inhibited responses for most beetles compared to low 4AA. Seven species were significantly deterred by high 4AA, including the latter three, and Hylastes longicollis, Hylastes nigrinus, Hylurgops reticulatus, and Ips latidens. Exceptions include Hylurgops subcostulatus, which was significantly attracted to both low and high 4AA, and I. pini, which was attracted to low and high 4AA in combination with low ethanol, but unaffected by either release of 4AA with high ethanol. Dendroctonus valens was significantly attracted to low 4AA and unaffected by high 4AA. Predators appeared to be less inhibited by 4AA than most bark beetles. Although 4AA can deter the attraction of some secondary bark beetles to ethanol in combination with alpha - and beta -pinene, this inhibition could be weakened for certain species by increasing ethanol release rates. 4-Allylanisole may have some utility for managing the behavior of secondary bark beetles sensitive to this compound.

A total of 1,176 individual predators belonging to seven orders and 22 families was collected. The most abundant species was Coniopteryx sp. (Coniopteryigidae: Neuroptera), and the most abundant family was Coccinellidae (Coleoptera). A total of 396 adult parasitoids was collected from 26 families of Hymenoptera and one Diptera family, with Encyrtidae being the most abundant. All other individuals were classified as potential food items and were identified only to order or, in some instances, family. A total of 5,812 potential food items was collected. Diversity of predators and parasitoids was greatest in May and June. Diversity of predators was highest on apple trees that were inter-planted with peach and cherry trees, whereas parasitoid diversity was greatest on peach trees and on insecticide treated apple trees. Chrysopids (Neuroptera), clerids (Coleoptera), and Leptothrips mali (Fitch) (Phlaeothripidae: Thysanoptera) were most commonly collected at dawn or during the night, suggesting that their role in orchards may be underestimated by sampling only during daylight hours. With the exception of Scelionidae and Platygastridae (Hymenoptera), parasitoids were most commonly collected during the night. Results indicate that peach trees are attractive to both predators and parasitoids and therefore may be a valuable addition to apple orchards to enhance the abundance of biological control species.

Fruit shipments that exceed a disease incidence threshold of 0.5% are redirected to alternative markets with substantial reductions in economic return to the producer. Because of this low tolerance, a sampling procedure with defined statistical properties is needed to determine disease incidence in the packinghouse. In this study, a sequential sampling plan was developed based on counts and dispersion patterns of infected fruit in 23 loads of mechanically harvested rabbiteye blueberries. Each load was sampled 20 to 100 times, with each sample containing 550 cm super(3) of fruit. Various dispersion statistics (k of the negative binomial distribution, Lloyd's index of patchiness, and Iwao's b) were computed, all of which suggested aggregation of infected fruit. Because k was variable across loads, Iwao's regression procedure, which does not assume a single frequency distribution with fixed parameters describing the counts of infected fruit, was used to develop upper and lower stop lines for sequential sampling. For alpha = 0.05 and assuming a total of 250 fruit per 550-cm super(3) sample, the resulting sampling plan would require only one sample to conclude that a load exceeds the threshold if the number of infected fruit in that sample is greater than four. A minimum of six samples would be needed to conclude that disease incidence in a load is below the threshold if the cumulative total of infected fruit in these samples is zero. Resampling analysis showed that most fruit loads could be classified reliably with <10 samples per load; for loads with a disease incidence very close to the 0.5% threshold, <50 samples were needed on average. Stop lines for sequential sampling for different fruit size classes are presented.

Recent evidence, however, indicates that in the northeastern United States, bird species that inhabit early successional habitats may be experiencing more widespread declines than their mature-forest counterparts. We compared the effect of group selection, a widely used form of uneven-aged forest management, and clearcutting on nest survival rates of early successional shrubland birds in the White Mountains of New Hampshire. There was no difference in daily nest survival rate between clearcuts (0.990) and groupcuts (0.987) for 16 bird species combined (n = 290), and no difference in daily nest survival rate between clearcuts (0.993) and groupcuts (0.987) for chestnut-sided warblers (Dendroica pensylvanica), the only species for which enough nests were found for separate analysis (n = 217). There was no difference in daily nest survival rates of all species combined between edge (0.983) and interior areas (0.992) of clearcuts (n = 204), and no difference in daily nest survival rates of chestnut-sided warblers between edge (0.984) and interior (0.993) areas of groupcuts (n = 156). Thus, our results suggest that clearcuts and groupcuts provide similar habitat for species of early successional shrubland birds that inhabit both clearcuts and groupcuts. Recent studies, however, indicate that some bird species that use larger openings such as clearcuts do not occupy smaller openings created by group selection, which may limit the utility of group selection in managing habitat for early successional shrubland birds.

Therefore, we performed a large-scale field experiment to determine whether the acetaminophen baits we developed could be used to reduce population levels of brown treesnakes on Guam. Toxic baits were made by inserting 80 mg of acetaminophen into dead neonatal mice, and these mouse baits were used to treat plots. Reference plots were baited with unadulterated baits. We used mark-recapture methods to estimate snake abundance on plots before treatment, monitored bait-take rates on treated plots for 30 days, and used mark-recapture to estimate snake populations post-treatment. Bait-take rates were reduced on treated plots by 83% relative to reference plots after 14 days, when they reached an asymptote. Using a robust design model in program MARK, snakes on reference plots had higher apparent survival rates (x = 0.3505) than those on treated plots (x = 0.0072) for the duration of the study, but estimates were influenced by snake movement between plots. When we accounted for movement using a multi-strata model, survival on treated plots was estimated as zero. High mobility of brown treesnakes presents difficulty for complete removal of snakes from large areas, but we conclude that acetaminophen baits may provide an effective and selective management tool for quickly and efficiently reducing populations of brown treesnakes on Guam.

When fecal material is exposed to oxygen, fermentation acids can be respired, and E. coli numbers increase. E. coli can survive for long periods of time in feces, but subsequent proliferation is dependent on its ability to re-enter the gastrointestinal tract via contaminated water and food. The oral-fecal lifestyle of E. coil is facilitated by its ability to survive the low pH of the human gastric stomach. Most strains of E. coli do not cause human disease, but some strains produce toxins and other virulence factors. Mature cattle carry E. coli O157:H7 without showing signs of infection, and beef can be contaminated with cattle feces at slaughter. Cattle manure is often used as a fertilizer by the vegetable industry, and E. coli from manure can migrate through the soil into water supplies. Sanitation, cooking and chlorination have been used to combat fecal E. coli, but these methods are not always effective. Recent work indicates that cattle diets can be modified overcome the extreme acid resistance of E. coli. When cattle were fed have for only a few days, colonic volatile fatty acid concentrations declined, pH increased, and the E. coli were no longer able to survive a pH shock that mimicked the human gastric stomach. E. coli in stored cattle manure eventually become highly acid resistant even if the cattle were fed hay, but these bacteria could be killed by sodium carbonate (150 mM, pH 8.5). Because the diet manipulations and carbonate treatments affected E. coli in general rather than specific serotypes, there is an increased likelihood of successful field application.

Understanding the variability of the fungal population associated with infection could improve disease control strategies. Sixty-six isolates of Fusarium graminearum associated with FHB were collected in North Carolina and tested for in vitro growth rate, in vitro production of deoxynivalenol (DON) and zearalenone, and pathogenicity on three cultivars of soft red winter wheat. Significant differences among isolates were found for all three traits. Randomly Amplified Polymorphic DNA (RAPD) analysis revealed high levels of genotypic diversity among isolates. Isolates of F. graminearum, F. culmorum, and F. avenaceum acquired from the Pennsylvania State University Fusarium Center were included for comparison in all tests. In vivo levels of DON were measured for the five isolates associated with the highest levels of disease and the five isolates associated with the lowest levels of disease, and no significant differences were found. However, all ten isolates produced detectable levels of DON in vivo. Mean disease ratings ranged from 3.4 to 96.4%, in vitro (DON) levels ranged from 0 to 7176.2 ppm, and zearalenone ranged from 0 to 354.7 ppm, among isolates. A multiple regression model using in vitro growth, in vitro DON, and zearalenone production, collection location, wheat cultivar of isolate origin, plot, tillage conditions, and previous crop as independent variables and percent blighted tissue as the dependent variable was developed. The cumulative R super(2) value for the model equaled 0.27 with in vitro rate of growth making the largest contribution. Analysis of phenotype and genotype among isolates demonstrated diversity in a single plot, in a single location, and in North Carolina. Genotypic and phenotypic diversity were significant under both conventional and reduced tillage conditions, and diversity was high regardless of whether the previous crop had been a host or non-host for F. graminearum. These data indicate a variable pathogen population of F. graminearum exists in North Carolina, and members of this population can be both highly pathogenic on wheat and produce high levels of detrimental toxins, indicating a potential threat for problems with FHB within the state.

The purpose of this study was to investigate the ability of these two-stage systems to remove nitrate and residual organics from treated water as compared to single-stage units. In the reversible flow system, the second-stage (i.e. follow) reactor is operated in series with the first-stage (i.e. lead) reactor. After a given period of operation, the flow regime is reversed so that the follow reactor becomes the lead one and vice versa. The active solids remaining in the follow reactor (previously the lead one) are capable of removing residual soluble organics and nitrates to levels below the concentrations provided by single-stage units particularly at HRTs as low as 0.5 h. Nitrate-nitrogen removal efficiency improved slightly from 98 to 99.5% for the single- and two-stage systems, respectively. Most notably, reversible flow reactors were found to reduce long-term effluent residual organics concentrations with an average of approximately 1/3 that of the single-stage system. Also the reversible flow system, with its design redundancy, demonstrated the ability to receive extreme shock loads with no sustained loss of treatment efficiency.

AN - 17840070; 4871272 AB - Inositol derivative compounds provide a nutrient source for soil bacteria that possess the ability to degrade such compounds. Rhizobium strains that are capable of utilizing certain inositol derivatives are better colonizers of their host plants. We have cloned and determined the nucleotide sequence of the myo-inositol dehydrogenase gene (idhA) of Sinorhizobium fredii USDA191, the first enzyme responsible for inositol catabolism. The deduced IdhA protein has a molecular mass of 34, 648 Da and shows significant sequence similarity with protein sequences of Sinorhizobium meliloti IdhA and MocA; Bacillus subtilis IolG, YrbE, and YucG; and Streptomyces griseus StrI. S. fredii USDA191 idhA mutants revealed no detectable myo-inositol dehydrogenase activity and failed to grow on myo-inositol as a sole carbon source. Northern blot analysis and idhA-lacZ fusion expression studies indicate that idhA is inducible by myo-inositol. S. fredii USDA191 idhA mutant was drastically affected in its ability to reduce nitrogen and revealed deteriorating bacteroids inside the nodules. The number of bacteria recovered from such nodules was about threefold lower than the number of bacteria isolated from nodules initiated by S. fredii USDA191. In addition, the idhA mutant was also severely affected in its ability to compete with the wild-type strain in nodulating soybean. Under competitive conditions, nodules induced on soybean roots were predominantly occupied by the parent strain, even when the idhA mutant was applied at a 10-fold numerical advantage. Thus, we conclude that a functional idhA gene is required for efficient nitrogen fixation and for competitive nodulation of soybeans by S. fredii USDA191.

A nonrevertible alcaligin mutant derived from the virulent strain 4609, designated DBB25, was constructed by insertion of a kanamycin resistance gene into alcA, one of the genes essential for alcaligin biosynthesis. The virulence of the alcA mutant in colostrum-deprived, caesarean-delivered piglets was compared with that of the parent strain in two experiments. At 1 week of age, piglets were inoculated with phosphate-buffered saline, 4609, or DBB25. Two piglets in each group were euthanatized on day 10 postinfection. The remainder were euthanatized at 21days postinfection. Clinical signs, including fever, coughing, and sneezing, were present in both groups. Nasal washes performed 7, 14, and 21 days postinoculation demonstrated that strain DBB25 colonized the nasal cavity but did so at levels that were significantly less than those achieved by strain 4609. Analysis of colonization based on the number of CFU per gram of tissue recovered from the turbinate, trachea, and lung also demonstrated significant differences between DBB25 and 4609, at both day 10 and day 21 postinfection. Mild to moderate turbinate atrophy was apparent in pigs inoculated with strain 4609, while turbinates of those infected with strain DBB25 developed no or mild atrophy. We conclude from these results that siderophore production by B. bronchiseptica is not essential for colonization of swine but is required for maximal virulence. B. bronchiseptica mutants with nonrevertible defects in genes required for alcaligin synthesis may be candidates for evaluation as attenuated, live vaccine strains in conventionally reared pigs.

The 728 km super(2) watershed is contained within the states of Georgia, South Carolina and North Carolina. The stream types of about 190 streams of various sizes were determined as perennial, intermittent or ephemeral using a combination of physical and biological indicators. The key indicators were defined as channel erosion into the landscape and aquatic insects. Comparisons were made between the measured stream characteristics and their hydrologic orders. The stream data indicated that most headwater order 1 streams were either ephemeral or intermittent. Order 2 streams were divided among intermittent, perennial and ephemeral. All order 3 streams and larger ones were perennial, except for one small, third order intermittent stream with an 18% channel gradient. The data suggest that the total 4670 km stream network was approximately equally divided between defined channels (28% perennial and 17% intermittent) and undefined channels (55% ephemeral). Changes in stream order produced exponential changes in the total number, mean segment length and total length of streams. The fine detail included about 15,630 order 1 channels with a combined length of 2740 km. Comparisons are provided between the estimated extent of stream types and the 'blue-line' streams identified on the US Geological Survey topographic contour maps at both 1:24,000 and 1:100,000 scales. Streams indicated on the 1:100,000 scale maps identified about 650 km of streams, while the 1:24,000 scale mapped the blue-line stream extent at 970 km. Of the estimated 1300 km of perennial streams, the topographic maps identified 50-75%, depending on scale. However, only about 14-21% of the entire stream network which includes perennial, intermittent and ephemeral streams were marked on the topographic contour maps. Recommendations are included for improving the consistency of how 'stream orders' and 'stream types' are delineated. Since water quality protection measures are often related to the stream type, improvement in identifying streams should improve stream protection design and help to prevent impacts on water quality and aquatic habitat.

Current research is investigating the utility of constructed wetlands for pesticide mitigation purposes, thereby restoring water quality enhancement capability to the area. Constructed wetland mesocosms (59-73 m x 14 m), located at the University of Mississippi Field Station (Lafayette County, MS), were amended with metolachlor to simulate a cropland runoff event. Target concentrations for wetlands were 73 and 147 mu g/l metolachlor in addition to an unamended control (0 mu g/l). Water, sediment, and plant samples were collected weekly for 35 days following metolachlor amendment. Samples were collected from sites, longitudinally distributed within each wetland, and analyzed for metolachlor using gas chromatography. Between 7 and 25% of measured metolachlor mass was in the first 30-36 m (from inflow) of wetlands immediately following application and simulated rainfall. Approximately 10% of measured metolachlor mass was in plant samples. Suggested wetland travel distances for effective mitigation of metolachlor runoff ranged from 100 to 400 m. According to the results from this research, aquatic receiving system impacts due to metolachlor runoff could be mitigated by using constructed wetlands as buffers. Landowners and government agencies can integrate this information into a water management plan, allowing for better control of both quantity and quality of runoff water from individual agricultural fields.

We also assessed the sensitivity of model results to the negative effects of allelochemicals on recruitment and growth of perennial grasses. ECOTONE simulates the recruitment, growth, and mortality of individual plants on a small plot (0.12 m super(2)) through time at an annual time step. A daily time step, multi-layer model of soil water dynamics (SOILWAT) was incorporated into ECOTONE to represent competition for soil water on a finer temporal scale. The model was parameterized for a shortgrass community in eastern Colorado, USA, using data available from the literature. Experimental simulations examined the effects of four soil textures and a range of levels of plant sensitivity to allelochemicals on the aboveground biomass of A. repens and of native perennial grasses. Simulation results showed that A. repens dominated the aboveground biomass on a plot only if native species were affected by allelopathic interactions. At moderate levels of plant sensitivity, A. repens became dominant faster and reached a higher proportion of the total biomass on fine- than on coarse-textured soils. Community composition and rate of A. repens dominance were more affected by the sensitivity of plant growth to allelochemicals than the sensitivity of species recruitment. Allelopathic interactions were an important component of the invasion dynamics of this perennial invasive weed, and further field investigations are warranted.

Solving the 'chicken and egg' problem in a bumblebee species AN - 17823068; 4862059 AB - In the social bee, Bombus terrestris, the two castes differ in size and physiology, but not in any other morphological and anatomical aspects. The size differences between the castes are the result of longer instar duration in prospective queen larvae. It appears that queen larvae are programmed to have a higher molting weight at the end of the 2nd, 3rd and 4th instars. Calculation of the growth ratio, the ratio between the logarithm of molting weight at two successive instars, revealed that queen larvae have a linear growth ratio over the entire larval development as predicted by Dyar's rule. In the worker larvae, in contrast, linearity of the growth ratio breaks after the second instar, resulting in larval molting at lower weights than expected by Dyar's rule. We therefore suggest that workers' development is abnormally shortened, either by parental manipulation or by adopting a different growth plan in response to the queen's signal.

F420 was characterized as an initial step in determining if this compound would be useful as a fluorescent marker for the detection of fecal and ingesta contamination. Using a single anion exchange chromatographic process, F420 was separated from other cell components of a Methanobrevibacter sp. cell culture. The extent of separation was determined spectroscopically. To aid in the development of possible techniques for the detection of fecal contamination using F420 as a marker, further spectroscopic investigation of F420 was conducted using steady-state and time-resolved fluorescence methods. The fluorescence lifetime of F420 in an elution buffer of pH 7.5 was found to be 4.2 ns. At higher pH values, the fluorescence decay, F(t), was best described by a sum of two exponentials: at pH 13, F(t) = 0.31 exp(-t/4.20 ns) + 0.69 exp(-t/1.79 ns). Further investigation using front-faced fluorescence techniques has shown that emission from F420 can be collected efficiently from samples of methanogen cell cultures as well as from fecal material.

AN - 70837479; 11347939 AB - Plastic tarps currently used during soil fumigation to control emissions have been shown to be permeable to fumigant vapors, resulting in appreciable losses to the atmosphere. New low-permeability films are being developed to reduce fumigant emissions and increase efficacy. A rapid, reliable, and sensitive method is required to measure the permeability of various films that may be used in new management practices. This manuscript presents an approach for estimating the mass transfer coefficient (h) of fumigant compounds across agricultural films. The h is a measure of the resistance to diffusion which, unlike other measures of permeability, is a property of the film-chemical combination and independent of the concentration gradient across the film. This method uses static sealed cells; fumigant vapor is spiked to one side of the film and the concentrations on both sides of the film are monitored until equilibrium. An analytical model is fitted to the data to obtain h. This model relies on a mass balance approach and includes sorption to and diffusion across the film membrane.

Reaction of humic acids with Cr(VI) resulted in a reduction of the peak area of thiols and an increase in the peak area of disulfides in the sulfur XANES spectra. Analysis of the sulfur XANES spectra in various systems indicates that the reduction of Cr(VI) by humic substances involves a thiol/disulfide redox couple analogous to that of the Cr(VI) reduction by the simple thiol-containing compounds cysteine and glutathione. A fraction of the hexavalent chromium present in industrially-contaminated soils was not reducible by thiols. Reduction of Cr(VI) to Cr(III) in soils by thiols has little effect on the pH of the system in contrast to the pH decrease resulting from reduction by Fe(II).

Fish were sampled at 0.5, 4, 12, 18, 24, 48 and 52 h from nine anatomical regions: the blood of the first two gill arches and blood of the third and fourth gill arches, nares, olfactory, optic and cerebellum regions of the brain, eye, heart and anterior kidney. The nare was the only organ yielding S. iniae at 0.5 h. The presence of S. iniae was evident in the cerebellum, blood of the gills, heart and kidney at 4 h and in the olfactory lobe at 12 h. The optic lobe and eye became culture-positive at 18 h. S. iniae CFU in nare, blood of the third and fourth gill arches and kidney remained elevated through 52 h, but declined in all other tissues at 52 h. S. iniae CFU in the eye remained low. We have shown that S. iniae is readily recovered from the nares of hybrid striped bass, and is able to penetrate the blood-brain barrier and rapidly disseminate to other tissues.

The effects of these volatile blends on herbivore behaviour have been investigated to only a limited extent, in part because of the assumption that herbivore-induced volatile emissions occur mainly during the light phase of the photoperiod. Because many moths--whose larvae are some of the most important insect herbivores--are nocturnal, herbivore-induced plant volatiles have not hitherto been considered to be temporally available as host-location cues for ovipositing females. Here we present chemical and behavioural assays showing that tobacco plants (Nicotiana tabacum) release herbivore-induced volatiles during both night and day. Moreover, several volatile compounds are released exclusively at night and are highly repellent to female moths (Heliothis virescens). The demonstration that tobacco plants release temporally different volatile blends and that lepidopteran herbivores use induced plant signals released during the dark phase to choose sites for oviposition adds a new dimension to our understanding of the role of chemical cues in mediating tritrophic interactions.

A Scholander pressure chamber was used to extract xylem sap from roots and branches cut from mature trees in early June and September. Root sap contained significantly greater concentrations of K, Ca, Mg, Mn, and Al than branch sap. Sap collected in June contained a signficantly greater concentration of Mn than sap collected in September. Sap concentration was related to forest location for N and Mn. Variations in concentrations of N and K were significantly related to the interaction of tree organ and month of collection. Variations in concentrations of P, Cu, Zn, and Fe were not attributable to tree organ, month of collection, or forest location. Patterns of element concentration in xylem sap compared to previously published data on soil solution chemistry indicated a high degree of homeostatic control of xylem sap chemistry. This control likely represents a significant allocation of resources within the tree energy budget.

Above-ground plant biomass did not differ between plants that were not exposed to these radionuclides and those that were exposed to soil containing super(137)Cs or super(90)Sr.After three harvests, bahia, johnson and switchgrass plants accumulated from 17.2 to 67.3% of the super(137)Cs and from 25.1 to 61.7% of the super(90)Sradded to the soil. Poultry litter and peat moss amendments increased aboveground plant biomass,activity of super(137)Cs or super(90)Sr in plant tissue, % accumulation of super(137)Cs or super(90)Sr from soil and the plant bioconcentration ratio at each harvest compared to the control (no amendment) treatment. The greatest increases in plant biomass, and radionuclide accumulation were observed with poultry litter foreach of the three grass species. Johnson grass had greater above ground plant biomass, activity of super(137)Cs and super(90)Sr in plant tissue, % accumulation of super(137)Cs or super(90)Sr from soil and bioconcentration ratio in each soil amendment, at eachharvest compared to bahia and switchgrass. Thegreatest accumulation of super(137)Cs and super(90)Sr was measured in johnson grass grown in soil that was amended with poultry litter. These results suggest that plant species selection and agronomic practices may need to be considered to maximize phytoremediation of radionuclide contaminated soils.

AN - 77038961; 11296838 AB - Rhipicephalus sanguineus (Latreille) were collected from the Corozal Army Veterinary Quarantine Center in Panama and characterized for resistance to five classes of acaricides. These ticks were highly resistant to permethrin, DDT, and coumaphos; moderately resistant to amitraz; and not resistant to fipronil when compared with susceptible strains. Resistance to both permethrin and DDT may result from a mutation of the sodium channel. However, synergist studies indicate that enzyme activity is involved. The LC50 estimate for permethrin was lowered further in the Panamanian strain then in susceptible strains with the addition of triphenylphosphate (TPP), but not with the addition ofpiperonyl butoxide (PBO). This suggests that esterases and not oxidases are responsible for at least some pyrethroid resistance. Elevated esterase activity and its inhibition by TPP were confirmed by native gel electrophoresis. The LC50 estimate obtained for coumaphos in the Panamanian strain was not lowered further than what was observed for susceptible strains by the addition of TPP or PBO. This indicates that enzyme activity might not be involved in coumaphos resistance. Resistance to amitraz was measured through a modification of the Food and Agriculture Organization Larval Packet Test. All tick strains were found to be susceptible to fipronil.

AN - 77027655; 11285927 AB - Gaseous emissions from swine (Sus scrofa) manure storage systems represent a concern to air quality due to the potential effects of hydrogen sulfide, ammonia, methane, and volatile organic compounds on environmental quality and human health. The lack of knowledge concerning functional aspects of swine manure management systems has been a major obstacle in the development and optimization of emission abatement technologies for these point sources. In this study, a classification system based on gas emission characteristics and effluent concentrations of total phosphorus (P) and total sulfur (S) was devised and tested on 29 swine manure management systems in Iowa, Oklahoma, and North Carolina in an effort to elucidate functional characteristics of these systems. Four swine manure management system classes were identified that differed in effluent concentrations of P and S, methane (CH4) emission rate, odor intensity, and air concentration of volatile organic compounds (VOCs). Odor intensity and the concentration of VOCs in air emitted from swine manure management systems were strongly correlated (r2 = 0.88). The concentration of VOC in air samples was highest with outdoor swine manure management systems that received a high input of volatile solids (Type 2). These systems were also shown to have the highest odor intensity levels. The emission rate for VOCs and the odor intensity associated with swine manure management systems were inversely correlated with CH4 and ammonia (NH3) emission rates. The emission rates of CH4, NH3, and VOCs were found to be dependent upon manure loading rate and were indirectly influenced by animal numbers.

The abilities of the SOIL-SOILN model to simulate water drainage and nitrate N fluxes from orchardgrass (Dactylis glomerata L.) were evaluated using data from a 3-yr field experiment. The soil is classified as a Hagerstown silt loam soil (fine, mixed, semiactive, mesic Typic Hapludalf). Nitrate losses below the 1-m depth from N-fertilized grazed orchardgrass were measured with intact soil core lysimeters. Five N-fertilizer treatments consisted of a control, urine application in the spring, urine application in the summer, urine application in the fall, and feces application in the summer. The SOIL-SOILN models were evaluated using water drainage and nitrate flux data for 1993-1994, 1994-1995, and 1995-1996. The N rate constants from a similar experiment with inorganic fertilizer and manure treatments under corn (Zea mays L.) were used to evaluate the SOILN model under orchardgrass sod. Results indicated that the SOIL model accurately simulated water drainage for all three years. The SOILN model adequately predicted nitrate losses for three urine treatments in each year and a control treatment in 1994-1995. However, it failed to produce accurate simulations for two control treatments in 1993-1994 and 1995-1996, and feces treatments in all three years. The inaccuracy in the simulation results for the control and feces treatments seems to be related to an inadequate modeling of N transformation processes. In general, the results demonstrate the potential of the SOILN model to predict NO3-N fluxes under pasture conditions using N transformation rate constants determined through the calibration process from corn fields on similar soils.

AN - 77027564; 11285912 AB - Phosphorus application in excess of crop needs has increased the concentration of P in surface soil and runoff and led many states to develop P-based nutrient management strategies. However, insufficient data are available relating P in surface soil, surface runoff, and subsurface drainage to develop sound guidelines. Thus, we investigated P release from the surface (0-5 cm depth) of a Denbigh silt loam from Devon, U.K. (30-160 mg kg-1 Olsen P) and Alvin, Berks, Calvin, and Watson soils from Pennsylvania (10-763 mg kg-1 Mehlich-3 P) in relation to the concentration of P in surface runoff and subsurface drainage. A change point, where the slopes of two linear relationships between water- or CaCl2-extractable soil P and soil test phosphorus (STP) (Olsen or Mehlich-3) meet, was evident for the Denbigh at 33 to 36 mg kg-1 Olsen P, and the Alvin and Berks soils at 185 to 190 mg Mehlich-3 P kg-1. Similar change points were also observed when STP was related to the P concentration of surface runoff (185 mg kg-1) and subsurface drainage (193 mg kg-1). The use of water and CaCl2 extraction of surface soil is suggested to estimate surface runoff P (r2 of 0.92 for UK and 0.86 for PA soils) and subsurface drainage P (r2 of 0.82 for UK and 0.88 for PA soils), and to determine a change point in STP, which may be used in support of agricultural and environmental P management.

AN - 77022700; 11285925 AB - In manure disposal systems, denitrification is a major pathway for N loss and to reduce N transport to surface and ground water. We measured denitrification and the changes in soil N pools in a liquid manure disposal system at the interface of a pasture and a riparian forest. Liquid swine manure was applied weekly at two rates (approximately 800 and 1600 kg N ha-1 yr-1) to triplicate plots of overland flow treatment systems with three different vegetation treatments. Denitrification (acetylene block technique on intact cores) and soil N pools were determined bimonthly for 3 yr. The higher rate of manure application had higher denitrification rates and higher soil nitrate. Depth 1 soil (0-6 cm) had higher denitrification, nitrate, and ammonium than depth 2 soil (6-12 cm). The vegetation treatment consisting of 20 m of grass and 10 m of forest had lower denitrification. Denitrification did not vary significantly with position in the plot (7, 14, 21, and 28 m downslope), but nitrate decreased in the downslope direction while ammonium increased downslope. Denitrification ranged from 4 to 12% of total N applied in the manure. Denitrification rates were similar to those from a nearby dairy manure irrigation site, but were generally a lower percent of N applied, especially at the high swine effluent rate. Denitrification rates for these soils range from 40 to 200 kg N ha-1 yr-1 for the top 12 cm of soil treated with typical liquid manure that is high in ammonium and low in nitrate.

AN - 70882848; 11370864 AB - The non-conventional yeast Yarrowia lipolytica is a suitable model for the study of yeast dimorphism. In order to identify genes that may be involved in the regulation of this process, random mutagenesis was performed. This led to the isolation of monomorphic mutants that had lost the ability to grow in a hyphal form both in liquid and on solid medium. Filamentation was restored to one of the mutants by transformation with a fragment of Y. lipolytica genomic DNA containing a single 2766-bp ORF. The predicted protein has a molecular weight of 99.6 kDa and is highly homologous to the protein kinases Cla4 of Candida albicans and Saccharomyces cerevisiae, which are members of the p21-activated kinase (PAK) family. Analysis of the putative protein sequence identified conserved C-terminal catalytic, and internal Cdc42p-binding regions, as well as a pleckstrin homology domain typical of PAK kinases. The results indicate that CLA4 is a single-copy gene located on the chromosome V of Y. lipolytica. Deletion of CLA4 is not lethal, but completely eliminates the ability to form filaments and to invade agar. A strain lacking a functional CLA4 gene exhibits an aberrant distribution of chitin in the cell wall, indicating a possible role for the Cla4 protein kinase in the maintenance of cell polarity in Y. lipolytica.

AN - 70846983; 11352533 AB - The trichothecenes T-2 toxin and deoxynivalenol (DON) are natural fungal products that are toxic to both animals and plants. Their importance in the pathogenicity of Fusarium spp. on crop plants has inspired efforts to understand the genetic and biochemical mechanisms leading to trichothecene synthesis. In order to better understand T-2 toxin biosynthesis by Fusarium sporotrichioides and DON biosynthesis by F. graminearum, we compared the nucleotide sequence of the 23-kb core trichothecene gene cluster from each organism. This comparative genetic analysis allowed us to predict proteins encoded by two trichothecene genes, TRI9 and TRI10, that had not previously been described from either Fusarium species. Differences in gene structure also were correlated with differences in the types of trichothecenes that the two species produce. Gene disruption experiments showed that F. sporotrichioides TRI7 (FsTRI7) is required for acetylation of the oxygen on C-4 of T-2 toxin. Sequence analysis indicated that F. graminearum TRI7 (FgTRI7) is nonfunctional. This is consistent with the fact that the FgTRI7 product is not required for DON synthesis in F. graminearum because C-4 is not oxygenated.

AN - 70659456; 11237510 AB - The intake of food cadmium (Cd) in microg/day over time can increase the body burden of this element. Some human populations that consume subsistence rice-based diets low in calcium (Ca), iron (Fe), and zinc (Zn) are more susceptible to Cd poisoning than populations that consume more nutritious diets. This study determined the effects of marginal deficiencies of these essential elements on the absorption and organ retention of Cd from a natural food that contains Cd, edible sunflower kernels (Helianthus annuus L.; SFK). Weanling female rats were fed diets containing 20% SFK in a 2x2x2 factorial design with marginal and adequate amounts of Ca, Zn, and Fe. Marginal Zn (11 mg/kg) and Fe (13 mg/kg), and Cd (0.18 mg/kg) were derived solely from 20% SFK. These amounts of Fe and Zn represented 39 and 90% of the NRC requirement for the rat, respectively. The marginal dietary Ca concentration (2.5 g/kg) was one-half the NRC requirement. After 5 weeks on the experiment, rats were fed 1 g of their respective diets containing SFK extrinsically labeled with 37 kBq 109Cd, and absorption was determined by whole-body counting techniques. Rats were then killed and organs collected for 109Cd assays. No effect of treatment on weight gain was observed; however, when dietary Zn was low, feeding marginal Ca elevated Cd absorption by 50% (P2.5-fold (P<0.001) over those fed adequate Fe. In contrast, the naturally occurring Zn in SFK that provided 90% of the rat's requirement was enough to deter excessive absorption of Cd and enough to alone prevent significant elevation of organ Cd. Organ content of 109Cd and Cd followed the same general pattern as whole-body absorption. These data show that marginal nutritional deficiencies of Ca and Fe can readily enhance the body burden of Cd that comes from the diet. Also, some natural competitors of Cd, such as Zn, contained in foods can independently minimize Cd absorption.

Results showed that more than half the inbreds accumulated aflatoxins at levels as low as or lower than the resistant U.S. lines GT-MAS:gk or MI82. In 10 selected aflatoxin-resistant or aflatoxin-susceptible inbreds, Aspergillus flavus growth, which was quantified using an A. flavus transformant containing a GUS- beta -tubulin reporter gene construct, was, in general, positively related to aflatoxin accumulation. However, one aflatoxin-resistant inbred supported a relatively high level of fungal infection, whereas two susceptibles supported relatively low fungal infection. When kernels of the 10 tested lines were profiled for proteins using sodium dodecyl sulfate-polyacrylamide gel electrophoresis, significant variations from protein profiles of U.S. lines were observed. Confirmation of resistance in promising African lines in field trials may significantly broaden the resistant germplasm base available for managing aflatoxin contamination through breeding approaches. Biochemical resistance markers different from those being identified and characterized in U.S. genotypes, such as ones inhibitory to aflatoxin biosynthesis rather than to fungal infection, may also be identified in African lines. These discoveries could significantly enhance the host resistance strategy of pyramiding different traits into agronomically useful maize germplasm to control aflatoxin contamination.

To determine if nonpectolytic hydrolase differences between low- and high-virulence isolates exist and, thus, could also potentially contribute to virulence differences, the present investigation was undertaken. Two A. flavus isolates, AF12 with low virulence and lacking pectinase P2C and AF13 with high virulence and producing pectinase P2C, were compared for production of nonpectolytic hydrolases after growth in 10% potato dextrose broth. Activity of amylases, cellulases, xylanases, and proteases was quantified using the radial diffusion/cup plate technique followed by differential staining. Culture filtrates also were subjected to native polyacrylamide gel electrophoresis. Both isolates produced amylases, proteases, and xylanases, whereas cellulases were not detected for either. AF13 produced more amylase than AF12, and this difference was supported by amylase isoform differences between isolates on native polyacrylamide gel electrophoresis gels. AF13 also produced more protease than AF12; however, isoform differences between isolates were inconclusive. These variations in other hydrolytic activities (besides pectinases) may contribute to virulence differences in cotton bolls between AF12 and AF13.

The acclimatory response was determined by comparing g sub(s) measured at 700 mu mol mol super(-1) [CO sub(2)] for plants grown at the two [CO sub(2)]. The direct effect of increasing [CO sub(2)] from 350 to 700 mu mol mol super(-1) was determined for plants grown at the lower concentration. Photosynthetic rates were measured concurrently with g sub(s). For all species, growth at the higher [CO sub(2)] significantly reduced g sub(s) measured at 700 mu mol mol super(-1) [CO sub(2)]. The reduction in g sub(s) caused by growth at the higher [CO sub(2)] was larger for all species on days with low leaf to air water vapour pressure difference for a given temperature, which coincided with highest conductances and also the smallest direct effects of increased [CO sub(2)] on conductance. For barley, there was no other evidence for stomatal acclimation, despite consistent down-regulation of photosynthetic rate in plants grown at the higher [CO sub(2)]. In wheat and potato, in addition to the vapour pressure difference interaction, the magnitude of stomatal acclimation varied directly in proportion to the magnitude of down-regulation of photosynthetic rate through the season. In sorghum, g sub(s) consistently exhibited acclimation, but there was no down-regulation of photosynthetic rate. In none of the species except barley was the direct effect the larger component of the net reduction in g sub(s) when averaged over measurement dates. The net effect of growth at elevated [CO sub(2)] on mid-day g sub(s) resulted from unique combinations of direct and acclimatory responses in the various species.

In a sorghum [Sorghum bicolor (L.) Moench] field experiment in which CO sub(2) [supplied using free-air CO sub(2) enrichment (FACE) technology] was crossed factorially with an irrigation treatment, soil aggregate (1-2 mm) water stability increased in response to elevated CO sub(2). Aggregate water stability was increased by 40% and 20% in response to CO sub(2), at ample and limited water supply treatments, respectively. Soil hyphal lengths of arbuscular mycorrhizal fungi (AMF) increased strongly (with a threefold increase in the dry treatment) in response to CO sub(2), and the concentrations of one fraction (easily extractable glomalin, EEG) of the AMF-produced protein glomalin were also increased. Two fractions of glomalin, and AMF hyphal lengths were all positively correlated with soil aggregate water stability. The present results further support the hypothesis that AMF can become important in global change scenarios. Although in this field study a causal relationship between hyphal length, glomalin and aggregate stability cannot be demonstrated, the present data do suggest that AMF could mediate changes in soil structure under elevated CO sub(2). This could be of great importance in agricultural systems threatened by erosional soil loss.

Incubation of eggs in each nest tree was at least 13 d and may have been as long as 16 d. The breeding male incubated and fed a nestling in one nest tree and the breeding female incubated and fed a nestling in the other nest tree until the nestlings were greater than or equal to 24 d old. Prior to fledging, both the breeding male and female were observed feeding both nestlings in both nest trees. The pair successfully fledged the two nestlings, a single fledging from each nest tree, during one nesting cycle. After the nestlings were fledged, both the male and female woodpeckers were observed feeding both fledglings about 350 m from the pair of nest trees. Our observations indicate that there are exceptions to the current theory that the contribution by the breeding male and female to incubation and feeding of nestlings is essential and that neither the male nor the female can normally rear young birds without the contribution of the other.

We examined the influence of various postcocooning (prewintering) temperature regimes on development, survival, emergence time, and longevity in both nondiapausing and diapausing forms of this species. Diapausing male and female M. rotundata required 27-30 d and 29-32 d, respectively, to develop from prepupae to emergence after incubation at constant 29 degree C, regardless of postcocooning treatments to which they were exposed. Likewise, longevity after emergence was not related to postcocooning temperatures and ranged from 5 to 6 d and 4 to 6 d for males and females, respectively. Elevated postcocooning temperatures were associated with a higher prevalence of nondiapausing individuals, those completing development from eggs through emergence as adults in the same summer season. Relevance of our results to the commercial production of alfalfa leafcutting bees is discussed.

Male plum curculios were most strongly attracted to volatiles released from females feeding on plums and to volatiles from mechanically punctured plums, which induced male copulations. Males were not attracted to volatiles from grouped males alone or a single male alone or synthetic grandisoic acid alone, and were just as attracted to odor of plums alone as to any of these stimuli in combination with plums, indicating either lack of enhancement of attraction to host plum odor by male-produced odors or synthetic grandisoic acid or lack of production or release of male-produced odors or problematic release of synthetic grandisoic acid. Females were attracted to odor of females alone, males alone, and synthetic grandisoic acid alone, but these attraction responses were not evident when plum odor was present (especially volatiles released from punctured plums), indicating the primary importance of host plum odor and potential influence of amount of male-produced odor in attraction of females. We concluded that female plum curculios may produce an odor attractive to male plum curculios, and both sexes produce an odor attractive to female plum curculios but in general, both male and female plum curculios were strongly attracted to host plum volatiles and only mildly attracted to conspecific odors or synthetic grandisoic acid under the conditions of our tests. We believe that attractive volatiles released from punctured plums should be used as source material to identify potential attractants for plum curculios.

Monogyne red imported fire ant, Solenopsis invicta Buren, colonies are highly territorial and aggressive toward non-nestmate conspecific workers. In contrast, workers from polygyne nests in the United States show no aggression toward workers from other conspecific colonies (polygyne or monogyne). Nests within a polygyne population form a 'supercolony,' with free exchange of workers and food between nests. The difference in conspecific nestmate recognition is a major distinguishing feature of the two S. invicta forms in the United States. We report here the discovery of an exception to this dichotomy. High levels of worker aggression are released by the introduction of newly mated queens into both polygyne and monogyne colonies. This suggests that nestmate recognition involving female sexuals does not follow the same mechanism used to explain nestmate recognition behavior between workers.

We obtained a comprehensive data set for a natural stand of ponderosa pine (Pinus ponderosa Laws.) and used these data to parameterize the physiologically based model, TREGRO. Representative trees of each of five tree age classes were selected based on population means of morphological, physiological, and nearest neighbor attributes. Differences in key physiological attributes (gas exchange, needle chemistry, elongation growth, needle retention) among the tree age classes were tested. Whole-tree biomass and allocation were determined for seedlings, saplings, and pole-sized trees. Seasonal maxima and minima of gas exchange were similar across all tree age classes. Seasonal minima and a shift to more efficient water use were reached one month earlier in seedlings than in older trees because of decreased soil water availability in the rooting zone of the seedlings. However, carbon isotopic discrimination of needle cellulose indicated increased water-use efficiency with increasing tree age. Seedlings had the lowest needle and branch elongation biomass growth. The amount of needle elongation growth was highest for mature trees and amount of branch elongation growth was highest for saplings. Seedlings had the highest biomass allocation to roots, saplings had the highest allocation to foliage, and pole-sized trees had the highest allocation to woody tissues. Seedlings differed significantly from pole-sized and older trees in most of the physiological traits tested. Predicted changes in biomass with tree age, simulated with the model TREGRO, closely matched those of trees in a natural stand to 30 years of age.

E. Smith), after selection for a single generation with transgenic Bacillus thuringiensis Berliner (Bt) cotton foliage. When fed Cry1Ac treated artificial diet, larvae whose parents had fed on transgenic Bt cotton leaves had significantly higher larval weights and a shorter time to pupation than those larvae whose parents had fed on conventional cotton leaves. In addition, there was no evidence to suggest any fitness or vigor differences existed from progeny of fall armyworms that fed previously on conventional or transgenic Bt cotton. Furthermore, tolerance of fall armyworms to Cry1Ac had a heritable component in the subsequent generation based on larval weights and time to pupation. These data show that using a common approach designed to control all intrinsically tolerant lepidopteran species of transgenic Bt cotton identically may not be desirable.

Data obtained from these experiments were analysed using the single-porosity Richards equation, as well as a variably saturated, dual-porosity model and a dual-permeability model for characterizing non-equilibrium water flow. The laboratory experiments were carried out on 0.10-m-long soil cores having an internal diameter of 0.10 m. Constant pressure heads of -0.10 and -0.01 m were used as the lower boundary condition. Each infiltration was followed by a single-rate evaporation experiment to re-establish initial conditions, and to obtain the drying soil hydraulic properties. Pressure heads inside the cores were measured using five tensiometers, while evaporative water loss from the top was determined by weighing the soil samples. The data were analysed to estimate parameters using a technique that combined a numerical solution of the governing flow equation (as implemented in a modified version of the Hydrus-1D software) with a Marquardt-Levenberg optimization. The objective function for the parameter estimation was defined in terms of pressure head readings, the cumulative infiltration rate, and the final total water volume in the core during upward infiltration. The final total water volume was used, as well as the pressure head readings during the evaporation part. Analysis of flow responses obtained during the infiltration experiment demonstrated significant non-equilibrium flow. This behaviour could be well characterized using a model of physical non-equilibrium that divides the medium into inter- and intra-aggregate pores with first-order transfer of water between the two systems. The analysis also demonstrated the importance of hysteresis. JF - European Journal of Soil Science AU - Simuenek, J AU - Wendroth, O AU - Wypler, N AU - Van Genuchten, MT AD - George E.

Using Cd/hemoglobin radioassay, this study detected significant increases in metallothionein (MT) concentrations in liver (4-fold), kidneys (2-fold), and duodenum (2-fold), but not jejunum, of mouse dams on days 13 and 20 of lactation. These increases occurred in the absence of cadmium exposure and were specific to the lactation period; dams 5 days after weaning showed MT levels that were similar to those of nonpregnant (NP) mice. Similarly, Northern blot analyses of livers from lactating mice demonstrated that MT mRNA concentrations in maternal liver during mid-lactation were 6-fold higher than those observed 5 days after pups were weaned. Gel filtration of final supernatants from the Cd/hemoglobin assay confirmed that the Cd-binding molecule induced during lactation was indeed metallothionein. In addition, chromatographic analyses of cytosols from tissues taken from dams administered small amounts of Cd (66 ng/mouse) showed that the trace amounts of Cd absorbed through the maternal gastrointestinal tract during mid-lactation were also bound to the MT. These results indicate MT induction in mouse dams occurs as a physiological consequence of lactation, requiring no external stimulus. This induced MT participates in binding low levels of dietary cadmium consumed by the dam. During lactation, elevated maternal MT may affect pathways for essential trace metals as well as sequester toxic metals harmful to the neonate. Multiparous humans may have increased risk of accumulating environmental Cd.

Distribution of [ super(14)C]1278-TCDD was low in all tissues examined. Metabolites were identified in urine, bile, and feces by negative ion FAB-MS and super(1)H-NMR, or GC/MS. The major fecal metabolite was a NIH-shifted hydroxylated TCDD. The bile contained a glucuronide conjugate of this hydroxy TCDD, and a diglucuronide conjugate of a dihydroxy-triCDD. The major metabolites in urine were glucuronide and sulfate conjugates of 4,5-dichlorocatechol.

The most common presentation is enterocolitis in children, presenting as fever and diarrhoea. A Y. enterocolitica multiple strain infection in twin infants was investigated. Methods and Results: One isolate was recovered from one patient and two morphologically-different isolates were recovered from the other infant. Biochemically, all isolates were identified as Y. enterocolitica group. The genomic DNA from each strain was purified and DNA fingerprinting was performed. The banding patterns observed for Y. enterocolitica isolates 2 and 3, from patients 1 and 2, respectively, were identical when comparing the presence or absence of major bands. However, Y. enterocolitica isolate 1, from patient 1, showed a distinctive banding pattern from isolates 2 and 3. Conclusions: The findings indicate that one infant was colonized by more than one strain of Y. enterocolitica, demonstrating that multiple strains can colonize and invade a patient. Significance and Impact of the Study: Recognition of multiple strain infections can be important in diagnosis, treatment and prognosis of Y. enterocolitica infections, as well as in disease epidemiology. The technique described here offers a straightforward method for strain comparison.

We tested the hypothesis that soil microbial diversity influences ecosystem function by quantifying denitrification enzyme activity among denitrifying bacteria isolated from two geomorphically similar soils with significantly different in situ nitrous oxide (N sub(2)O) emission rates. We sampled soil from two southwest Michigan sites on the same soil series that differed in plant community composition and disturbance regime - a conventionally-tilled agricultural field and a never-tilled successional field. We isolated denitrifying bacteria from these soils, characterized them based on their fatty acid profiles, and compared denitrifier community composition for the two fields. For 31 representative isolates, we measured the sensitivity of nitrous oxide reductase (Nos) - which catalyzes the reduction of N sub(2)O to N sub(2) - to low oxygen concentrations. Of the 93 denitrifying bacteria isolated from the agricultural field and 63 from the successional field, fatty acid profiles suggested the presence of 27 denitrifying taxa with only 12 common to both soils. In each field type the four numerically dominant taxa were either rare or absent in the other field. In addition, we found substantial diversity in the sensitivity of isolate Nos enzymes to oxygen, indicating that the taxonomic diversity present among denitrifiers in these two soils is functionally significant. These results demonstrate a clear physiological basis for differences in denitrifier community function previously described and indicate that differences in denitrifier community composition alone can potentially influence in situ N sub(2)O production.

Excised jowl skin produced significantly greater counts of the three types of bacteria than sponge swabs. Aerobic bacteria, coliforms and injured coliforms recovered by sponge swabbing carcasses before chilling were 11.6%, 0.9% and 11.0% of excised samples, respectively; the corresponding percentages recovered after chilling were 23.9%, 11.1% and 5.0%. Numbers of all bacteria present on the post-chill carcasses were substantially lower than on the pre-chill carcasses. Excision usually produced more countable plates for coliforms and injured coliforms on chilled carcasses than sponge swabbing and therefore, is more suitable in estimating low numbers of faecal bacteria on chilled carcasses. To explore the possible structural bases for these findings, skin samples were inoculated with 10 super(2)-10 super(7) cfu cm super(-2) faecal bacteria and examined by scanning electron microscopy. Chilled samples showed bacteria and biofilm embedded in superficial crevices, which underlies a possible reason for the lower recovery of bacterial cells by the sponge swabbing. The study indicates that the differences between sampling techniques may be a result of the chilling process of swine carcasses. JF - Letters in Applied Microbiology AU - Yu, S.

While not completely ignored, the application of multifactor, hierarchical ecosystem classifications are limited despite their widespread use in other regions of the eastern United States. We present one of the few truly integrated ecosystem classifications for the southeastern Coastal Plain. Our approach is iterative, including reconnaissance, plot sampling, and multivariate analysis. Each ecosystem is distinguished by differences in physiographic setting, landform, topographic relief, soils, and vegetation. The ecosystem classification is ground-based, incorporating easily observed and measured factors of landform, soil texture, and vegetative cover associated into ecological species groups identified by two-way indicator species analysis. Canonical correspondence analyses (CCA) that measure the degree of distinctness among ecosystems using different combinations of physiographic, soil, and vegetation datasets are used to verify the classification. The hierarchical ecosystem classification provides a framework for sustainable resource management of our study landscape as an alternative to traditional cover-type or vegetation-based classifications in the southeastern Coastal Plain. This ecosystem classification provides a structural framework that mimics biological organization, by physical drivers, ensuring that information on various ecosystem components are available to assist management decisions made at the ecosystem level.

Plant symptoms in addition to phyllody may include chlorosis, virescence, stunting, or crown proliferation. In this report we describe a new phytoplasma in association with strawberry leafy fruit (SLF) disease in Maryland. Diseased plants exhibited fruit phyllody, floral vireseence, leaf chlorosis, and plant stunting. Phytoplasmal 16S rDNA was amplified from SLF diseased plants by using the polymerase chain reaction (PCR) primed by primer pair P1/P7 and was reamplified in nested PCR primed by primer pair R16F2n/R2 (F2n/R2) as previously described. These results indicated the presence of a phytoplasma, designated SLF phytoplasma. Identification of SLF phytoplasma was accomplished by restriction fragment length polymorphism (RFLP) analysis of DNA amplified in PCR primed by F2n/R2, using endonuclease enzyme digestion with AluI, HhaI, KpnI, HaeIII, MseI, HpaII, RsaI, and Sau3AI. Phytoplasma classification was done according to the system of Lee et al. RFLP analyses of rDNA amplified in three separate PCRs gave identical patterns. On the basis of collective RFLP patterns of the amplified 16S rDNA, the SLF phytoplasma was classified as a member of group 16SrIII (group III, X-disease phytoplasma group). The HhaI RFLP pattern of SLF 16S rDNA differed from that of the apparently close relative, clover yellow edge (CYE) phytoplasma, and all other phytoplasmas previously described in group III. Based on these results, SLF phytoplasma was classified in a new subgroup, designated subgroup K (III-K), within group III. The 1.2 kbp DNA product of PCR primed by primer pair F2n/R2 was sequenced, and the sequence deposited in GenBank under Accession No. AF175304. Results from putative restriction site analysis of the sequence were in agreement with the results from actual enzymatic RFLP analysis of rDNA amplified from phylloid strawberry fruit. Although the sequence similarity between the 1.2-kbp fragment from the 16S rDNA of SLF phytoplasma and that of CYE phytoplasma was 99.9%, the HhaI RFLP pattern of SLF rDNA supports the conclusion that the SLF phytoplasma may be closely related to, but is distinct from, CYE and other strains that are classified in group III. These findings contribute knowledge about the diversity of phytoplasmas affiliated with group III and the diversity of phytoplasmas associated with diseases in strawberry.

Previous sequence analysis of the pertactin gene identified two regions predicted to encode amino acid repeat motifs. Recent studies have documented DNA sequence heterogeneity in both regions. The present study describes additional variants in these regions, which form the basis for six novel pertactin types. Immunoblotting demonstrated phenotypic heterogeneity in pertactin consistent with the predicted combined sizes of the repeat regions. A revised system for classifying B. bronchiseptica pertactin variants is proposed.

Experiments were conducted to evaluate the effectiveness of the breeding approach. Backcross derivatives of pearl millet Tift 23DB were developed with rust resistance from 18 Burkina Faso landraces, 3 Pennisetum glaucum subsp. monodii accessions, and 2 elite inbreds (1 from India and 1 from the United States). Four cycles of open pollination were made, the last two in the field in rust epidemics. Cytoplasmic male-sterile (CMS) counterparts of the populations in the A sub(4) cytoplasm were included and advanced simultaneously with the B population. Hybrids with Tift 383 were produced on CMS cycles 1 (C1) through C4. Frequency of hybrid seedlings with resistance increased with each cycle, and frequencies averaged 18 to 38% in C1 to C4 hybrids, respectively, when inoculated with five single-uredinium isolates of Puccinia substriata var. indica. The hybrid populations and Tifleaf (TL)1 and TL2 were evaluated in three yield trials in 1998 to 1999. Disease-free forage dry matter yields did not differ among hybrids. Across trials, area under the disease progress curve (AUDPC) of TL1 and TL2 averaged 1,307, C1 and C2 averaged 914, and C3 and C4 averaged 604. Final severities of TL1 and TL2 averaged 67%, C1 and C2 averaged 47%, and C3 and C4 averaged 30%. When analyzed by regression analysis, AUDPC was reduced 12.2%, final rust severity was reduced 13.3%, and digestible biomass was increased 4.1% per cycle.

Fecal coliforms were reduced from 4.6 x 10 to 2.0 x 10 cells per ml 2 days after treatment and were nondetectable within 4 days. Total anaerobic bacteria were reduced from 8.4 x 10 super(10) to 1.5 x 10 cells per ml after 2 days and continued to be suppressed to that level after 14 days. If the concentration of carvacrol or thymol were doubled (13.3 mM), either could be used to obtain the same inhibitory fermentation effect. We conclude that carvacrol or thymol may be useful as an antimicrobial chemical to control pathogens and odor in stored livestock waste.

Study areas were established in 36 plantations across northwest and west-central Montana on Champion International Corporation's timberland (currently owned by Plum Creek Timber Company). Site quality indices used in the equation were available water index (available water capacity multiplied by the natural logarithm of annual precipitation) and site index (SI) of the previous stand. Three-year height increment was modeled as a function of tree size, vigor, and competition by using available water index (AWI) and SI separately as site quality indicators in the same equation form. Comparison of the two equations suggest that soil factors in combination with precipitation data may be a useful alternative to traditional tree-based site quality indices in predicting height increment of young stands where site index is not known or is poorly estimated.

Its National Leadership Team established water as a top-priority natural resource issue for the next decade. As part of this renewed commitment to watershed management, 15 large watersheds were chosen around the country as laboratories for a new Forest Service approach to their public and private land and research programs. Refocusing USFS on its watershed stewardship roots, these projects provide a commitment aimed at integrating efforts across the agency and across land ownerships in building long-term watershed and community-based partnerships. These 15 watersheds are serving as prototypes for more visionary management of ailing watersheds and forest ecosystems that provide water to millions of Americans and habitats for thousands of animal and plant species. The $11 million provided by the USFS national office in Fiscal Year 2000 was leveraged by over 2:1 by the partners. To make this effort successful, a business plan was written for each watershed project.

The direct and indirect effects of this potential increase in temperature on terrestrial ecosystems and ecosystem processes are likely to be complex and highly varied in time and space. The Global Change and Terrestrial Ecosystems core project of the International Geosphere-Biosphere Programme has recently launched a Network of Ecosystem Warming Studies, the goals of which are to integrate and foster research on ecosystem-level effects of rising temperature. In this paper, we use meta-analysis to synthesize data on the response of soil respiration, net N mineralization, and aboveground plant productivity to experimental ecosystem warming at 32 research sites representing four broadly defined biomes, including high (latitude or altitude) tundra, low tundra, grassland, and forest. Warming methods included electrical heat-resistance ground cables, greenhouses, vented and unvented field chambers, overhead infrared lamps, and passive night-time warming. Although results from individual sites showed considerable variation in response to warming, results from the meta-analysis showed that, across all sites and years, 2-9 years of experimental warming in the range 0.3-6.0 degree C significantly increased soil respiration rates by 20% (with a 95% confidence interval of 18-22%), net N mineralization rates by 46% (with a 95% confidence interval of 30-64%), and plant productivity by 19% (with a 95% confidence interval of 15-23%). The response of soil respiration to warming was generally larger in forested ecosystems compared to low tundra and grassland ecosystems, and the response of plant productivity was generally larger in low tundra ecosystems than in forest and grassland ecosystems. With the exception of aboveground plant productivity, which showed a greater positive response to warming in colder ecosystems, the magnitude of the response of these three processes to experimental warming was not generally significantly related to the geographic, climatic, or environmental variables evaluated in this analysis. This underscores the need to understand the relative importance of specific factors (such as temperature, moisture, site quality, vegetation type, successional status, land-use history, etc.) at different spatial and temporal scales, and suggests that we should be cautious in "scaling up" responses from the plot and site level to the landscape and biome level. Overall, ecosystem-warming experiments are shown to provide valuable insights on the response of terrestrial ecosystems to elevated temperature.

AN - 70831910; 11342234 AB - The chloroimide 3,3-dichloro-4-(dichloromethylene)-2,5-pyrrolidinedione, a tetrachloroitaconimide, is the principal mutagen produced by chlorination of simulated poultry chiller water. It is the second most potent mutagenic disinfection by-product of chlorination ever reported. Six of seven new synthetic analogs of this compound are direct-acting mutagens in Ames tester strain TA-100. Computed energies of the lowest unoccupied molecular orbital (E(LUMO)) and of the radical anion stability (DeltaH(f)(rad)-DeltaH(f)) from MNDO-PM3 for the chloroimides show a quantitative correlation with the Ames TA-100 bacterial mutagenicity values. The molar mutagenicities of these direct acting mutagenic imides having an exocyclic double bond fit the same linear correlation (lnM(m) vs. E(LUMO); lnM(m) vs. DeltaH(f)(rad)--DeltaH(f)) as the chlorinated 2(5H)-furanones, including the potent mutagen MX, 3-chloro-4-(dichloro-methyl)-5-hydroxy-2(5H)-furanone, a by-product of water chlorination and paper bleaching with chlorine. Mutagenicity data for related haloimides having endocyclic double bonds are also given. For the same number of chlorine atoms, the imides with endocyclic double bonds have significantly higher Ames mutagenicity compared to their structural analogs with exocyclic double bonds, but do not follow the same E(LUMO) or DeltaH(f)(rad)-DeltaH(f) correlation as the exocyclic chloroimides and the chlorinated 2(5H)-furanones.

AN - 70648070; 11182461 AB - Quantitative risk assessments are now required to support many regulatory decisions involving infectious diseases of animals. Current methods, however, do not consider the relative values of historical and recent data. A Markov-chain model can use specific disease characteristics to estimate the present value of disease information collected in the past. Uncertainty about the disease characteristics and variability among animals and herds can be accounted for with Monte Carlo simulation modeling. This results in a transparent method of valuing historical testing information for use in risk assessments. We constructed such a model to value historical testing information in a more-transparent and -reproducible manner. Applications for this method include trade, food safety, and domestic animal-health regulations.

AN - 70626223; 11166998 AB - The efficacy of an aroA Salmonella serovar typhimurium modified live vaccine to decrease internal egg contamination after oral challenge of hens with egg-contaminating Salmonella serovar enteritidis was assessed. Challenge was with a mixed phenotype of S. enteritidis that had virulence characteristics previously associated with enhanced oral invasiveness and egg contamination in chickens. Immunized birds had fewer positive ovary/oviduct pools and lower cfu g(-1) cecal contents than did non-immunized birds, but the differences were not significant. The number of positive intestinal (duodenum, jejunum, ileum) and organ (spleen, kidney, liver) pools following challenge from each treatment group were equivalent. Most importantly, immunization did not decrease egg contamination.

An F. verticillioides strain was transformed with a beta -glucuronidase (GUS) reporter gene (uidA) construct to facilitate fungal growth quantification and then inoculated onto endosperm-wounded and non-wounded kernels of the above-corn lines. To serve as a control, an A. flavus strain containing the same reporter gene construct was inoculated onto non-wounded kernels of GT-MAS:gk. Results showed that, as in a previous study, non-wounded GT-MAS:gk kernels supported less growth (six- to ten-fold) of A. flavus than did kernels of a susceptible control. Also, non-wounded kernels of GT-MAS:gk and MI82 supported less growth (two- to four-fold) of F. verticillioides than did susceptible kernels. Wounding, however, increased F. verticillioides infection of MI82, but not that of GT-MAS:gk. This is in contrast to a previous study of A. flavus, where wounding increased infection of GT-MAS:gk rather than MI82 kernels. Further study is needed to explain genotypic variation in the kernel response to A. flavus and F. verticillioides kernel infections. Also, the potential for aflatoxin-resistant corn lines to likewise inhibit growth of F. verticillioides needs to be confirmed in the field.

The enantiomer of LCB, containing all-D amino acids (DCB), was synthesized to examine its antibacterial and binding properties. The conformation of DCB was compared to its enantiomer by circular dichroism. Both the L- and D-peptides showed an identical induction of a-helical secondary structure. However, binding studies between Lipopolysaccharide (LPS) and DCB or LCB were studied with a dimethylmethylene blue spectrophotometric assay, showing the two enantiomeric peptides differed in their interaction with LPS. Antibacterial activity of DCB was determined against three Gram-negative bacteria, Pantoea agglomerans (ATCC 27996), Escherichia coli (ATCC 8739), and Pseudomonas aeruginosa (ATCC 17648), giving comparable results to LCB.

AN - 76991830; 11262071 AB - The solution conformational properties of the mycotoxin fumonisin B(1) have been studied using molecular dynamics methodology. Fumonisins have been shown to inhibit sphinganine (sphingosine) N-acyltransferase (ceramide synthase) and show a wide range of toxic effects in many animals. This study of the solution properties of fumonisin B(1) attempts to add to the structural models necessary for the understanding of the binding and activity properties. The computational method uses a box with periodic boundaries, filled with explicit TIP3P water molecules, the substrate fumonisin B(1), and selected counterions for charge neutrality. The starting structure of fumonisin B(1) is added to the box by excluding water molecules. The explicit image method using 12-A cutoffs is applied to the system and molecular dynamics are carried out on different starting conformations at 300 K in 100-picosecond (ps) steps. Examination of the resulting equilibrated conformations suggests that the structure is relatively extended and that previous computational studies in vacuo, showing a compact folded structure, may not be consistent with the solution structure.

AN - 76989631; 11261998 AB - Fumonisins, mycotoxins produced by certain species of Fusaria, are commonly found worldwide as contaminants in maize. This paper reports the development of a rapid, portable fluorescence polarization-based assay for fumonisins in maize. The assay was based on the competition of unlabeled fumonisin, from a sample, with a fluorescently tagged fumonisin (FB(1)-FL) for a fumonisin-specific monoclonal antibody in solution. The fluorescence polarization (FP) of the tagged fumonisin was increased upon binding with the antibody. In the presence of free toxin, less of the FB(1)-FL was bound and the polarization signal was decreased. The assays were very simple to perform, requiring only mixing of an aqueous extract of maize with the tagged fumonisin and antibody, and required <2 min per sample, excluding extraction time. Two permutations of the assay were tested, one with each sample matrix serving as its own blank, and the other with all of the samples compared relative to a PBS blank with normalization of the data similar to an ELISA. The limit of detection, defined as the toxin content associated with a fluorescence polarization signal 5 standard deviations from that of a fumonisin-free control, was 0.5 microg of FB(1)/g in spiked maize. Recoveries from spiked maize over the range of 0.5-20 ppm averaged 94.3 +/- 13.8%. Forty-eight samples of field-contaminated maize were tested by the FP and an established HPLC method, with a good correlation between the two (r(2) = 0.85-0.88). For these samples, the two variations of the FP assay also compared well to one another (r(2) = 0.97), suggesting the assay principle is very robust. The results, combined with the speed and ease of use for the assay, suggest that this technology has substantial potential as a screening tool for mycotoxins in foods.

AN - 71384735; 14768810 AB - Volatile components of Pachycoris stallii scent gland secretions and the bug's host plant, Croton californicus, were identified by gas chromatography and mass spectroscopy. The predominant compounds isolated from C. californicus fruit and leaves were beta-myrcene and beta-caryophyllene. Metathoracic gland secretions of P. stallii contained mostly (E)-2-hexenal, (E)-4-oxo-2-hexenal, (E)-2-hexenyl acetate, and n-tridecane. In males, n-tridecane was present throughout the metathoracic gland, but in females this compound was found only in the median reservoir/accessory gland. (E)-2-Hexenal was present throughout the gland of female bugs, but in males was primarily present in the median reservoir/accessory gland. (E)-4-Oxo-2-hexenal and n-dodecane were isolated from the median reservoir/accessory gland of male and female bugs. Metathoracic glands were sexually monomorphic. Data from chemical analyses and anatomical observations suggest that dorsal abdominal glands of adults were apparently obsolescent. In nymphs, dorsal abdominal glands produced (E)-2-hexenal, (E )-4-oxo-2-hexenal, n-dodecane, n-tridecane, and tetradecanal. The proportion of the predominant constituent, (E)-4-oxo-2-hexenal, decreased from 72% in the first instar to 47% in the fourth instar. Proportions of tetradecanal and n-tridecane were greater in the fourth instar than in the first instar. Observations of dissected glands indicated that median and posterior dorsal abdominal glands of all nymphal instars were more developed than anterior dorsal abdominal glands. Scanning electron micrography revealed the presence of polygonal microsculpturing on the integument surrounding the ostioles of metathoracic and dorsal abdominal glands. Chemical, anatomical, and behavioral data indicated that P. stallii has a chemical defense system based on short-chain carbonyl compounds and that this system is directed against arthropods. The abundance of arthropod natural enemies apparently has forced P. stallii to maintain this defense system despite feeding on a toxic host plant.

AN - 70680023; 11233106 AB - The efficacy of photo active dyes as insecticides depends on the ingestion of the dye by the target insect and the activity of the dye at sensitive sites or on essential chemical functions. The site of this activity in insects is not understood, but we have found that certain chemical additives enhance the toxicity of phloxine B in the Mexican fruit fly. A series oftests with commercial adjuvants was performed under laboratory conditions that demonstrated a multifold decrease in the LD50 of phloxine B concentration and a decrease in the time required for photodynamic action to kill the flies. A total of 22 commercial adjuvants was tested. Of these, six were selected for evaluation under field cage conditions in comparison with a non-insecticide control bait (no treatment) and a phloxine B check bait with no adjuvant. Mortality was estimated by counting dead flies, feeding was estimated by fly counts at feeding stations, survival was estimated by trapping flies after the treatment period. In all cases the adjuvants increased the rate of mortality and decreased numbers surviving the treatment. Significant differences between adjuvants and both check and control were observed for mortality rates and the three best adjuvants, SM-9, Kinetic, and Tween60, induced significantly more mortality than the other adjuvants, the control, or the check. Feeding rates and survival rates indicated that the adjuvants increase the effectiveness of phloxine B in a predictable manner. The adjuvants appear to be active inside the insect rather than increasing the solubility of the dye in the bait medium. We propose that the addition of 1% vol:vol of the best adjuvant, Tween60 to the proteinaceous bait with 0.5% phloxine B will enhance toxicity as well as improve mixing and other characteristics of the bait.

AN - 70674050; 11239939 AB - Pigs are considered an important source of Toxoplasma gondii infection for humans. A major strategy for immune prophylaxis of toxoplasmosis in swine is the understanding of the immune response against T. gondii infection. The phenotype of peripheral blood mononuclear cells (PBMC) and the kinetics of interferon-gamma (IFN-gamma), interleukin-12 (IL-12) and interleukin-10 (IL-10) transcriptional changes were characterised in miniature swine following infection. A total of 66, 4-9-month-old miniature swine were used for three experiments performed over a period of 2 years. All pigs were fed iota1000 oocysts of the VEG strain of T. gondii and blood samples were obtained on the day of inoculation and at days 3, 6, 10, 17, 25, 32 and 40 after infection. An increase in expression of activation markers CD25 and SLA-DQ was detected in the first week of infection. A significant increase in the percentage of CD8+cells was observed in the second week of infection. Relative competitive RT-PCR analysis indicated an increase in IFN-gamma mRNA as well as a reduction in IL-10 mRNA during the second week post infection. Increase in IL-12 transcription was not observed until the fourth week of infection. The ability of the pigs to respond to T. gondii infection by simultaneously inducing pro-inflammatory cytokines early and anti-inflammatory cytokines later is a likely indication of the requirement to strike a balance between controlling parasite growth and avoiding cytokine toxicity.

AN - 70669451; 11233133 AB - Laboratory-reared predators, the insidious flower bug, Orius insidiosus (Say), and big-eyed bug Geocoris punctipes (Say), were exposed to 10 insecticides, including three newer insecticides with novel modes of action, using a residual insecticide bioassay. These species are important predators of several economic pests of cotton. Insecticides tested were: azinphos-methyl, imidacloprid, spinosad, tebufenozide, fipronil, endosulfan, chlorfenapyr, cyfluthrin, profenofos, and malathion. There was considerable variation in response between both species tested to the insecticides. Tebufenozide and cyfluthrin were significantly less toxic to male O. insidiosus than malathion. Tebufenozide was also significantly less toxic to female O. insidiosus than malathion. Imidacloprid, tebufenozide, and spinosad were significantly less toxic to male G. punctipes than chlorfenapyr, endosulfan, and fipronil. Spinosad, tebufenozide, and azinphos-methyl were significantly less toxic to female G. punctipes than fipronil and endosulfan. Fecundity of O. insidiosus was significantly greater in the spinosad treatment compared with other treatments including the control. Consumption of bollworm, Helicoverpa zea (Boddie), eggs by O. insidiosus was significantly lower in the fipronil, profenofos, and cyfluthrin treatments compared with other treatments including the control. Consumption of H. zea eggs by G. punctipes was significantly lower in the malathion, profenofos, endosulfan, fipronil, azinphos-methyl, and imidacloprid treatments compared with the control. Egg consumption by G. punctipes was not significantly different in the tebufenozide treatment compared with the control. The lower toxicity of spinosad to G. punctipes is consistent with other reports. Based on these results, the following insecticides are not compatible with integrated pest management of cotton pests: malathion, endosulfan, profenofos, fipronil, and cyfluthrin; while imidacloprid, tebufenozide, azinphos-methyl, and spinosad should provide pest control while sparing beneficial species.

AN - 70658766; 11233123 AB - A diet-incorporation larval bioassay was developed to measure the response of codling moth, Cydia pomonella (L.), to the benzoylhydrazine insecticides tebufenozide and methoxyfenozide. The bioassay tested neonates and third, fourth, and fifth instars from a laboratory colony and neonates and fourth instars from a pooled population collected from five certified-organic apple orchards. Bioassays were scored after 6 and 14 d. No differences between the laboratory and field population were found for either insecticide. Significant differences were found in the response of third and fifth instars between the 6 and 14 d bioassays, primarily due to a high proportion of moribund larvae in the shorter assay. Larval age had a significant effect in bioassays and was more pronounced in 6- versus 14-d tests. Fifth instars were significantly less susceptible to both insecticides than other stages, while responses of third and fourth instars were similar. The response of neonates was significantly different from third and fourth instars to tebufenozide but not with methoxyfenozide in the 14-d test. Field bioassays excluded the use of fifth instars and were scored after 14 d. LC50s estimated for 18 field-collected populations varied five- and ninefold for tebufenozide and methoxyfenozide, respectively. The responses of all but six field-collected populations were significantly different from the laboratory strain. Five of these six populations were collected from orchards with no history of organophosphate insecticide use. The LC50 for methoxyfenozide of one field-collected population reared in the laboratory for three generations declined fourfold, but was still significantly different from the laboratory population. These data suggest that transforming current codling moth management programs in Washington from a reliance on organophosphate insecticides to benzoylhydrazines may be difficult.

Cupric chloride was toxic to gypsy moth larvae. Ferrous and ferric chloride were inhibitory to larval growth and development as well as to virus activity. Strontium chloride was inhibitory to virus activity but had no apparent effects on gypsy moth larvae.

AN - 70642178; 11233003 AB - Control of Salmonella spp. during the earliest phases of broiler production may provide the best opportunity to reduce human pathogens on processed broiler carcasses. Application of the "Nurmi concept" has been demonstrated to be an effective means in reducing Salmonella colonization among broiler chicks. In 1989, Aho et al. developed a competitive exclusion (CE) culture for control of Salmonella spp., whereas a mucosal competitive exclusion culture (MCE) developed in the United States was originally created to control Campylobacter colonization (Stern et al., 1995). The major differences in the two patents were the higher level of anaerobic culture required, the degree of epithelial scraping and washing of the ceca, media used for subculturing, and the culture incubation temperatures (35 C vs. 42 C). The CE and MCE were compared for efficacy in reducing Salmonella and Campylobacter colonization in broiler chicks. Nine adult birds (three for each of three replicates) were slaughtered, and each of a bird's paired ceca were used to produce corresponding antagonistic microflora, which were administered to day-of-hatch chicks. The chicks (a total of 210) were challenged 24 h later with Salmonella and Campylobacter and were killed 1 wk later, and levels of the pathogens were determined. Ninety CE-treated birds were significantly more colonized by Salmonella typhimurium than those 90 chicks treated with the MCE microflora (3.97 log 10 cfu/g cecal contents vs. 1.25 log 10 cfu/g cecal contents). Also, Campylobacter spp. colonization of these birds was significantly higher for CE-treated birds when compared with MCE-treated birds (6.96 log 10 cfu/g cecal contents vs. 5.03 log 10 cfu/g cecal contents). These results can be useful in developing intervention strategies to reduce chicken colonization by Salmonella and Campylobacter.

AN - 70639796; 11172671 AB - Citrus flavonoids encompass a diverse set of structures, including numerous flavanone and flavone O- and C-glycosides and methoxylated flavones. Each of these groups of compounds exhibits a number of in vitro and in vivo anti-inflammatory and anticancer actions. These biological properties are consistent with their effects on the microvascular endothelial tissue. Evidence suggests that the biological actions of the citrus flavonoids are possibly linked to their interactions with key regulatory enzymes involved in cell activation and receptor binding. The citrus flavonoids show little effect on normal, healthy cells, and thus typically exhibit remarkably low toxicity in animals. The citrus flavonoids extend their influence in vivo through their induction of hepatic phase I and II enzymes, and through the biological actions of their metabolites. Evidence clearly indicates to the potential health promoting properties of these dietary compounds.

Inoculation levels were 10(2), 10(3), or 10(4) cells per sample. The samples were allowed to remain at room temperature for 15, 30, or 60 min before addition of enrichment broth. When chick pad samples were inoculated with 102 cells, by 15 min 40% of the samples had detectable levels of Campylobacter, and by 30 to 60 min Campylobacter could be detected in only 20% of the samples. With samples of pine shavings, only 25% of those inoculated with 103 cells were positive for Campylobacter after 15 min and only 5% were positive for Campylobacter after 30 min. When 104 cells were inoculated onto litter, Campylobacter was recovered from 20% of the samples at 15 min and 15% of the samples after 30 min. Eggshells were also found to be a harsh environment. When the inoculum was 102 at 15 min, 8 of 10 samples were positive for Campylobacter but at 60 min only 10% of the samples remained positive for Campylobacter. The current cultural methods may not be adequate for recovering low numbers of Campylobacter from dry samples. Campylobacter may be present but culturally undetectable in the commercial hatchery and hatchery environment.

AN - 70607083; 11271760 AB - Conventional and experimental washing formulations were applied with a commercial flatbed brush washer under conditions representative of commercial practice to determine their efficacy in decontaminating apples inoculated with a nonpathogenic Escherichia coli strain. Golden Delicious apples (18 kg) inoculated with E. coli were mixed with approximately 109 kg of uninoculated Fuji apples (distinctly different in appearance) in a wet dump tank containing 1,325 liters of water at 20 degrees C for 15 min. The combined apples were washed in a flatbed brush washer with the following washing solutions: water at 20 degrees C, water at 50 degrees C, 200 ppm of chlorine (pH 6.4) at 20 degrees C, 8% trisodium phosphate at 20 degrees C, 8% trisodium phosphate at 50 degrees C, 5% hydrogen peroxide at 20 degrees C, 5% hydrogen peroxide at 50 degrees C, 1% APL Kleen 245 at 50 degrees C, and two-stage washing treatments using the combination of 1% APL Kleen 245 at 20 or 50 degrees C followed by 5% hydrogen peroxide at 35 or 50 degrees C. None of the washing treatments tested under the conditions of this experiment significantly reduced the E. coli populations on the inoculated apples or in cider made from these apples, probably as a consequence of the inability of this washing system to inactivate or remove the bacterial cells in inaccessible calyx and stem areas of apples. These results are important because they demonstrate the need for new fruit washing technology that can overcome this limitation. Also, there was no significant cross-contamination of the Fuji apples in the dump tank. Significant cross-contamination of cider, made with uninoculated apples, occurred in the hammer mill and/or the press cloth when these units were not sanitized following a trial with inoculated apples.

Community-based approaches are supported because citizens have local knowledge, understand local conditions, can practice direct democracy, & can help develop solutions to problems of integrated & sustainable forest management. However, there is little information available to evaluate the effectiveness of community-based strategies. This study evaluates how well three participatory techniques -- a mail survey, focused conversations with existing community groups, & community dinners -- meet three key community-oriented criteria: representativeness, working toward identification of communitywide common good, & incorporation of values & beliefs into the discussion. The evaluation conducted in this study indicates that the techniques produce positive results for two of these criteria, but may not be representative of the communities as a whole. 4 Tables, 39 References.

For more than 4 centuries the Puerto Rican economy depended almost entirely on agriculture, but sociopolitical changes early in the 20th century resulted in a shift to industry. This shift in the economy, and an increase in population, has resulted in an increase in urban areas. This study describes the rate and distribution of urban growth on the island of Puerto Rico from 1977 to 1994 and the resulting influence on potential agricultural lands. Urban extent and growth were determined by interpreting aerial photographs and satellite imagery. The 1994 urban coverage was combined with a soil coverage based on agricultural potential to determine the distribution of urban areas relative to potential farmlands. Analyses showed that in 1977, 11.3% of Puerto Rico was classified as urban. After 17 years, urban areas had increased by 27.4% and urban growth on soils suitable for agriculture had increased by 41.6%. This represents a loss of 6% of potential agricultural lands. If this pattern of encroachment by urban growth into potential farmlands continues, Puerto Rico's potential for food production in the future could be greatly limited.

AN - 1859338753; 11106839 AB - The objective of this study was to determine whether differences in toxicity between Tall larkspur (Delphinium barbeyi) and Duncecap larkspur (D. occidentale) were genetically inherent within the species, or due to environmental influences unique to the different regions where they grow. There was no difference in the concentration of the toxic alkaloids between the two species when grown in common gardens. However, both species had higher concentration of toxic alkaloids when grown in the southern Rocky Mountain region which is characterized by summer monsoonal thunderstorms, compared to summer drought in the north. In a unique occurrence where Duncecap larkspur grew beside Tall larkspur, toxic alkaloids were very low in Duncecap larkspur, but total alkaloid concentration was often higher than in Tall larkspur.

Because sarcopenia is not the result of a disease, it is seen in all aged adults. Sarcopenia markedly increases the risk of disability and loss of functional capacity in the elderly. The mechanisms underlying sarcopenia are complex and are reviewed here. It is not clear at this time which factors are most important in determining the severity or rate of development of sarcopenia. While progressive resistance training clearly can reverse and prevent sarcopenia, little is known about the mechanisms by which aged muscle adapts to training, or whether these adaptations reflect reversal of direct pathophysiological processes or compensation by activation of separate pathways from those leading to the deterioration in the first place. As populations in developed countries continue to age, diagnosing, treating, and preventing sarcopenia will be progressively more important to the health and well-being of modern societies.

AN - 18071924; 5122552 AB - Almost any type of sample has some utility when estimating population quantities. The focus in this paper is to indicate what type or combination of types of sampling can be used in various situations ranging from a sample designed to establish cause-effect or legal challenge to one involving a simple subjective judgment. Several of these methods have little or no utility in the scientific area but even in the best of circumstances, particularly complex ones, both probabilistic and non-probabilistic procedures have to be used because of lack of knowledge and cost. We illustrate this with a marbled murrelet example.

E. Smith), respectively, were found to exist among commercially available Cry1A(c) transgenic Bacillus thuringiensis Berliner (Bt) varieties. Using a quantification assay (ELISA) to measure the levels of delta -endotoxin in two of these varieties ('DP 451B/RR' and 'NuCOTN 33B'), differences in the amount of delta -endotoxin present in various plant parts was correlated with larval survival of bollworms and larval development of fall armyworms throughout the growing season. Larvae that were fed on DP 451B/RR completed development faster and exhibited better survivorship than those larvae fed NuCOTN 33B, whereas lower levels of delta -endotoxin were generally detected in plant parts from DP 451B/RR compared with NuCOTN 33B. These differences may impact population dynamics of these pests which may be a critical factor in managing resistance to Bt. Furthermore, the utility of using this system for providing information to the grower concerning varietal choices may be more common in the future.

However, these data are limited for the soils of south Florida. Also, there are no standard methods for determining soil hydraulic properties such as saturated hydraulic conductivity, erodibility, and water retention values. The objectives of this study were: 1) to calculate soil erodibility using results from rainfall simulation; 2) to compare different methods for calculating soil hydraulic conductivity, soil erodibility, and soil water retention values; and 3) to evaluate how the results from these different methods would affect evapotranspiration, storm water runoff, crop growth, and soil erosion in the model. Three typical soils from the region were used for this study: Krome (sandy loam, moderately well drained), Chekika (silty clay loam, poorly drained), and Perrine Marl (sandy loam, very poorly drained). Field research (including model calibration and rainfall simulation) was used to determine soil water parameters. While using various methods to determine soil parameters (calibrated, measured, and estimated) in a hydrologic model, significant discrepancies of simulated hydrologic variables were observed. Therefore, caution should be exercised when predicting critical parameters for hydrologic models. If a model, such as the Everglades Agro-Hydrology Model (EAHM), is used for comparison of different management practices, slight errors in estimated parameters are acceptable. However, if the model is used to assess possible changes in the hydrologic regime of south Florida, the accuracy of simulated values is important and in need of further investigation.

The solvent strength of the water is affected by both the system's temperature and the amount and type of cosolvent modifier that is added to the water, which causes a reduction in the dielectric constant of water. In the present work, the solubilities of the triazine pesticides atrazine, cyanazine, and simazine were measured in pure and modified water at temperatures ranging from 50 to 125 degree C and at a pressure of 50 atm. The solubility data were obtained using a static solubility apparatus with on-line liquid chromatographic (LC) detection. By increasing the temperature of the water, the solubilities of the triazine pesticides increased approximately 3-fold in pure water for each 25 degree C temperature increment. Cyanazine was 5 times more soluble than atrazine and an order of magnitude more soluble than simazine at 100 degree C. The solubility of atrazine was also measured in ambient and hot water modified with ethanol and urea. At 100 degree C, the solubility of atrazine is doubled when the water is modified with urea, and is increased over an order of magnitude when ethanol is used as modifier. The data, therefore, indicate that adding a cosolvent to water in addition to increasing the system temperature increases the solubilities of triazine pesticides in subcritical water. It was further determined that the solutes do not thermally degrade or hydrolyze at the temperatures reported in this study.

The (-)-ceralure B1 enantiomer was significantly more attractive than the (+)-ceralure B1 antipode. Dose-response studies of the above compounds demonstrated that (-)-ceralure B1 and to a lesser extent, racemic ceralure B1, captured consistently more male flies than trimedlure, the current male attractant used in detection programs. Longevity tests demonstrated that, over a three-week period, both (-)-ceralure B1 and racemic ceralure B1 caught significantly more flies than trimedlure. The synthesis of specific enantiomers of ceralure B1 shows great promise as a male attractant that could replace trimedlure for detection and delimitation in action programs aimed at this exotic pest.

Copulation duration decreased significantly with increasing male length or increasing relative size (male length divided by female length). Female length had no effect on copulation duration. We interrupted copulation at 20 or 40 min at both 25 and 15 degree C to determine the interacting effects of male size, temperature, and copulation duration on probability of insemination. Insemination probabilities increased with increasing male size, increasing temperature, and increased duration of copulation. Large males were more successful than small males at inseminating females at cool temperatures and for severely shortened copulations. Results are consistent with the hypothesis that males of this species experience physical difficulties either in achieving intromission or in forcing sperm through the aedeagus, and that larger body size in males lessens these difficulties.

Relative to all other tree-age classes, seedlings exhibited greater tissue carbohydrate concentration in stems and foliage, and greater shifts in the time at which maximum and minimum carbohydrate concentration occurred. To determine the effect of environmental stressors on tissue carbohydrate concentration, two tree-age classes (40-year-old and mature) were compared at three sites along a well-established, long-term O sub(3) and N deposition gradient in the San Bernardino Mountains, California. Maximum carbohydrate concentration of l-year-old needles declined with increasing pollution exposure in both tree-age classes. Maximum fine root monosaccharide concentration was depressed for both 40-year-old and mature trees at the most polluted site. Maximum coarse and fine root starch concentrations were significantly depressed at the most polluted site in mature trees. Maximum bole carbohydrate concentration of 40-year-old trees was greater for the two most polluted sites relative to the cleanest site: the bole appeared to be a storage organ at sites where high O sub(3) and high N deposition decreased root biomass.

If seed sources are from differently adapted populations, then the relative performance of progeny from crosses among populations may decrease with an increase in genetic differences of parents and in the differences of parental environments to the transplant location. We evaluated the potential for such outbreeding depression by hybridizing individuals from six different populations of Lotus scoparius var. scoparius and L. s. var. brevialatus. We used allozyme data to calculate genetic distances between source populations, and compiled climatic data and measured soil traits to estimate environmental distances between source populations. We found significant outbreeding depression following controlled crosses. In the greenhouse, the success of crosses (seeds/flower x seedlings/seed) decreased with increasing genetic distance between populations revealing genetically based outbreeding depression unrelated to local adaptation. After outplanting to one native site (in situ common garden), field cumulative fitness of progeny (survival x fruit production) decreased significantly with mean environmental distance of the parental populations to the transplant site, but not with genetic distance between the crossed populations. This result is consistent with a disruption of local adaptation. At the second, ecologically contrasting common garden, where low survival reduced statistical power, field cumulative fitness (survival x progeny height) did not decrease significantly with either environmental distance or genetic distance. Overall, intervariety crosses were 40 and 50% as fit (seeds/flower x seedlings/seed x survival x fruits at the first garden or x height at the second) as intravariety crosses. These results suggest that the cumulative outbreeding depression was caused by a combination of genetically based ecological differences among populations and other genomic coadaptation. We conclude that mixing genetically differentiated seed sources of Lotus scoparius may significantly lower the fitness of augmented or restored populations. Genetic and environmental similarities of source populations relative to the transplant site should be considered when choosing source materials, a practice recommended by recent seed transfer policies. Geographic separation was not a good surrogate for either of these measures.

Peripheral blood heterophils were isolated and exposed to known inhibitors of signal transduction pathways for either 20 min (staurosporin, genistein, or verapamil) or 120 min (pertussis toxin) at 39 degree C. The cells were then stimulated for 30 min at 39 degree C with opsonized SE. Phagocytosis, luminol-dependent chemoluminescence (LDCL), and beta -D glucuronidase release were then evaluated in vitro. The G-protein inhibitor pertussin toxin markedly inhibited (>80%) phagocytosis of opsonized SE. Both the protein kinase inhibitor (staurosporin) and calcium channel inhibitor (verapamil) reduced phagocytosis in a dose response manner. Genistein, a tyrosine kinase inhibitor, had no effect on phagocytosis. Staurosporin had a marked inhibitory effect on LDCL (> 90%) while genistein had a dose responsive inhibition on LDCL. Both verapamil (40-45%) and pertussin toxin (50-55%) had a statistically significant, but less biologically significant effect on LDCL. Genistein significantly reduced the degranulation (78-81%) of heterophils by opsonized SE. Staurosporin also reduced degranulation by 43-50%, but neither verapamil nor pertussis toxin had a significant effect on degranulation. These findings demonstrate that distinct signal transduction pathways differentially regulate the stimulation of the functional activities of avian heterophils. Pertussin toxin-sensitive, Ca super(++)-dependent G-proteins appear to regulate phagocytosis of opsonized SE, protein kinase C-dependent, tyrosine kinase-dependent protein phosphorylation plays a major role in LDCL, and tyrosine kinase(s)-dependent phosphorylation regulates primary granule release.

The isolation ratio of the competing challenge strains was monitored and varied, depending upon the isolates used. A PCR-restriction fragment length polymorphism assay of the flagellin gene (flaA) was used to discriminate between the chick-colonizing isolates. Our observations indicated that the selected C. jejuni colonizers dominated the niche provided by the chicken ceca. Chicken isolates from the flaA type 7 grouping generally had numerical superiority over the human isolates when they were administered in our 1-day-old chick model. Our results suggest that it is possible to use combinations of C. jejuni chicken isolates as a defined bacterial preparation for the competitive exclusion of human-pathogenic C. jejuni in poultry.

In liquid culture, sugars stimulated only 5-27% germination of B. bassiana and less than or equal to 11% germination of P. fumosoroseus, whereas, yeast extract or peptone stimulated 95-100% germination. In the absence of additional nutrients, agar alone stimulated approximately 50% germination. Storing spores for different periods of time did not alter their general response to exogenous nutrients. When spores were germinated before being applied to third instar B. argentifolii, mortality was as much as 2.45 times greater and occurred more rapidly than that for fresh spores. For ungerminated conidia, the mean time to death from infection was 5.45 (SE = 0.16) and 4.74 (SE = 0.08) days for application rates of 37 and 144 conidia . mm super(-2), respectively. When conidia were germinated before application, infection times dropped to 4.58 (SE = 0.16) and 4.45 (SE = 0.10) days, respectively. A likely explanation for the greater pathogenicity and virulence of germinated over ungerminated B. bassiana conidia is that only a fraction of the spores applied to whitefly nymphs actually germinate on the cuticle. For some specialized applications, such as greenhouse production systems, it may be beneficial to germinate spores immediately prior to application.

Rhizomorph production by A. ostoyae from woody inocula in soils from red spruce stands at three elevations at each of five mountainous sites in the eastern United States was inhibited completely in the mineral soil from all elevations at all sites, and was also reduced significantly in the organic horizon from the upper two elevations at three of the sites. Inhibition was correlated with concentrations of metal ions in the soil. Growth of rhizomorphs into an agar medium containing lead and other heavy metals was inhibited for isolates of A. ostoyae from red spruce, but not for an isolate of Armillaria gallica from sugar maple; aluminium inhibited rhizomorph growth of isolates of both species. Mycelial growth of all four root and butt rot fungi was inhibited by lead, aluminium and other heavy metals depending on the solubility and concentration of metal and pH of the medium; growth inhibition was usually greater at an initial pH of 3.5 than at pH 4.5. Metal ions inhibited radial growth of Armillaria species more than that of the other three fungi. Rhizomorph growth of Armillaria was inhibited more than radial growth. Because local spread of A. ostoyae occurs frequently by means of rhizomorph growth between near roots, increases in lead, aluminium and other metals in the forest floor may contribute to this fungus' scarcity in high elevation soils and reduced incidence of infection at these sites in the eastern United States.

Interspersed within the 240 kb Mla complex are three families of resistance gene homologs (RGHs). Probes from the Mla-RGH1 family were used to identify three classes of cDNAs. The first class is predicted to encode a full-length CC-NBS-LRR protein and the other two classes contain alternatively spliced, truncated variants. Utilizing a cosmid that contains a gene corresponding to the full-length candidate cDNA, two single-cell expression assays were used to demonstrate complementation of AvrMla6-dependent, resistance specificity to B. graminis in barley and wheat. The first of these assays was also used to substantiate previous genetic data that the Mla6 allele requires the signaling pathway component, Rar1, for function. Computational analysis of MLA6 and the Rar1-independent, MLA1 protein reveals 91.2% identity and shows that the LRR domain is subject to diversifying selection. Our findings demonstrate that highly related CC-NBS-LRR proteins encoded by alleles of the Mla locus can dictate similar powdery mildew resistance phenotypes yet still require distinct downstream signaling components.

AN - 17829289; 4863148 AB - Marker genes are indispensable for identifying rare plants that have taken up foreign DNA. Unfortunately, their presence is also often problematic for commercial biotechnology products because of consumer concerns and regulatory requirements over the presence of "excess" exogenous DNA. Over the past decade, researchers have developed several approaches for excising marker DNA from transgenic plants and crops, including several site-specific recombination systems (e.g., lox/Cre recombinase, Flp recombination target (FRT)/Flp recombinase, or Rs/R recombinase). In this issue, Zuo et al. present a system that makes the site-specific recombination approach more convenient and applicable for a wider range of plants.

The need to feed ( similar to 125 Tg N) and to provide energy ( similar to 25 Tg N) for the growing world population drives this trend. This increase in reactive N comes at, in some instances, significant costs to society through increased emissions of NO sub(x), NH sub(3), N sub(2)O and NO sub(3) super(− ) and deposition of NO sub(y) and NH sub(x).In the atmosphere, increases in tropospheric ozone and acid deposition (NO sub(y) and NH sub(x)) have led to acidification of aquatic and soil systems and to reductions in forest and crop system production. Changes in aquatic systems as a result of nitrate leaching have led to decreased drinking water quality, eutrophication, hypoxia and decreases in aquatic plant diversity, for example. On the other hand, increased deposition of biologically available N may have increased forest biomass production and may have contributed to increased storage of atmospheric CO sub(2) in plant and soils. Most importantly, synthetic production of fertilizer N has contributed greatly to the remarkable increase in food production that has taken place during the past 50 years.The development of policy to control unwanted reactive N release is difficult because much of the reactive N release is related to food and energy production and reactive N species can be transported great distances in the atmosphere and in aquatic systems. There are many possibilities for limiting reactive N emissions from fuel combustion, and in fact, great strides have been made during the past decades. Reducing the introduction of new reactive N and in curtailing the movement of this N in food production is even more difficult. The particular problem comes from the fact that most of the N that is introduced into the global food production system is not converted into usable product, but rather reenters the biosphere as a surplus. Global policy on N in agriculture is difficult because many countries need to increase food production to raise nutritional levels or to keep up with population growth, which may require increased use of N fertilizers. Although N cycling occurs at regional and global scales, policies are implemented and enforced at the national or provincial/state levels. Multinational efforts to control N loss to the environment are surely needed, but these efforts will require commitments from individual countries and the policy-makers within those countries.

Warm summer temperatures with frequent dew periods favored spread of the disease in wheat fields in Manitoba and Saskatchewan. The Canada Prairie Spring wheat cultivars (AC Vista, AC Foremost, AC Crystal) were susceptible to leaf rust, while the bread wheat cultivars with leaf rust resistance genes Lr16 and Lr13 or Lr34 (AC Majestic, AC Domain, AC Barrie) had high to moderate levels of leaf rust infections. Bread wheat cultivars AC Cora, AC Minto, Pasqua, and McKenzie had trace to low levels of leaf rust infection. Thirty-four virulence phenotypes of P. triticina were identified on 16 Thatcher lines, which are near-isogenic for leaf rust resistance genes. Phenotypes with virulence to Lr16 increased to 25% of isolates in Manitoba and Saskatchewan in 1998. Forty-three isolates were also tested for virulence to plants with the adult plant resistance genes Lr12, Lr13, Lr34, and Lr13,34. Most isolates had virulence to Lr12 and Lr13. All isolates had lower infection type on adult plants with Lr34 compared with Thatcher.

Studies were conducted at Fargo, North Dakota (from 1989 to 1990) to determine the effect of BYDV infection on yield and malt quality parameters in barley. Three malting cultivars varying in yield potential and malting characteristics were artificially inoculated at the seedling stage with a North Dakota BYDV isolate of the PAV serotype. Overall yields were reduced 32.5 to 38% in 1989 and 8.5 to 19.8% in 1990 by BYDV infection. Thousand-kernel weight (3.2 to 14.9%) and kernel plumpness (11.9 to 38.9%) also were reduced. Kernel color and three malt quality parameters ( alpha -amylase, malt recovery, and wort viscosity) were not affected by BYDV infection. Increases in wort protein (2.5 to 14.5%) and diastatic power (3.8 to 12.6%), and decreases in malt extract (1.1 to 5.6%) were found. Most notably, total protein increased 4.6 to 17.5% with BYDV infection. Higher proportions of thin seed, as a result of BYDV infection, contributed to the effects on several quality parameters. In summary, the negative effect of BYDV infection on overall quality is significant and should be considered when assessing the impact of this disease. Although annual BYD disease-related losses are typically not extensive in the Midwestern malting barley region, the incorporation of host resistance into recommended cultivars would ameliorate the negative effects of BYD disease on crop quality as well as on yield.

Sepharose resins demonstrated the best properties for DNA purification when compared to other gel filtration resins, and Sepharose 2B was the most efficient purification resin based upon flow rate and the elution of DNA and humic acids from the columns. A method for purifying large solution volumes of DNA extract economically was also developed using low-cost disposable Disposaflex columns. Crude DNA extracts of cattle feedlot soil and aquifer sediment impacted by animal and human wastes were easily purified using the Disposaflex column method regardless of whether a gentle chemical lysis or a bead mill homogenization DNA extraction method was employed.

One mechanism used by LFB to protect themselves from bacteriophage attack is restriction of foreign DNA. Three plasmids, pER16, pER35, and pER36, from three different strains of the thermotolerant dairy fermentation bacterium Streptococcus thermophilus were sequenced. One of these plasmids, pER35, isolated from S. thermophilus ST135, encoded a type IC restriction-modification (R-M) system very similar to those encoded on plasmids pIL2614 in Lactococcus lactis subsp. lactis and pND861 in Lactococcus lactis biovar diacetylactis. The high degree of identity between the R-M systems encoded on pER35, pIL2614, and pND861 indicated the potential for horizontal transfer of these genes between different species of lactic fermentation bacteria. Similar to the functional R-M system encoded on pIL2614 that protects the mesophilic L. lactis subsp. lactis against phage attack, the R-M system on pER35 most likely functions in the same role in S. thermophilus ST135. The plasmid pER16 was found to encode the specificity subunit of the R-M system, but not the R or M subunits. In addition, all three plasmids encoded proteins that are present on other S. thermophilus plasmids, including a protein for rolling-circle replication (RepA) and a low-molecular-weight stress protein (Hsp). The presence of a complete R-M system encoded on a plasmid in S. thermophilus, a species that often lacks plasmids, is novel and may be beneficial for protecting S. thermophilus from bacteriophage attack under dairy fermentation conditions.

Beginning in the early 1980s, the herbicide-based weed control program emphasized the application of atrazine (ATR) or cyanazine (CYN) and metolachlor (MET) for both broadleaf and grass control. Between 1992 and 1995, concentrations of ATR, desethylatrazine (DEA), desisopropylatrazine (DIA), CYN and MET were measured in rainwater, both shallow and deep vadose zone water, and well water. Results show that the frequency of herbicide detections and the range and distribution of occurrences are dependent upon both landscape position and temporal inputs of recharge water from rainfall. Generally, DIA was observed more frequently and in higher mean concentration in well water than DEA, while DEA was observed more frequently than DIA in vadose zone groundwater. A chromatographic analogy is suggested to explain the occurrence patterns observed for both parent herbicide and degradation products within the unsaturated zone water. Analysis of rainwater samples collected during this time also revealed low concentrations of ATR, CYN and MET, with the timing of the detections indicative of non-local transport. Results show that the deep loess soil conducts both water and agricultural chemicals relatively rapidly and as such represents a production system which is vulnerable to contamination of shallow groundwater by herbicide-derived chemicals. Results also illustrate the importance of including major herbicide degradation products in water resource impact assessment studies.

AN - 72397607; 11789916 AB - To study the impact of ozone (O3) and O3 plus CO2 on aspen growth, we planted two trembling aspen clones, differing in sensitivity to O3 in the ground in open-top chambers and exposed them to different concentrations of O3 and O3 plus CO, for 98 days. Ozone exposure (58 to 97 microl l(-1)-h. total exposure) decreased growth and modified crown architecture of both aspen clones. Ozone exposure decreased leaf, stem, branch, and root dry weight particularly in the O3 sensitive clone (clone 259). The addition of CO2 (150 microl l(-1) over ambient) to the O3 exposure counteracted the negative impact of O3 only in the O3 tolerant clone (clone 216). Ozone had relatively little effect on allometric ratios such as, shoot/root ratio, leaf weight ratio, or root weight ratio. In both clones, however, O3 decreased the shoot dry weight, shoot length ratio and shoot diameter. This decrease in wood strength caused both current terminals and long shoots to droop and increased the branch angle of termination. These results show that aspen growth is highly sensitive to O3 and that O3 can also significantly affect crown architecture.

AN - 72396840; 11789918 AB - The Intergovernmental Panel of Climate Change (IPCC) has concluded that the greenhouse gases carbon dioxide (CO2) and tropospheric ozone (O3) are increasing concomitantly globally. Little is known about the effect of these interacting gases on growth, survival, and productivity of forest ecosystems. In this study we assess the effects of three successive years of exposure to combinations of elevated CO2 and O3 on growth responses in a five trembling aspen (Populus tremuloides) clonal mixture in a regenerating stand. The experiment is located in Rhinelander, Wisconsin, USA (45 degrees N 89 degrees W) and employs free air carbon dioxide and ozone enrichment (FACE) technology. The aspen stand was exposed to a factorial combination of four treatments consisting of elevated CO2 (560 ppm), elevated O3 (episodic exposure-90 microl l(-1) hour(-1)), a combination of elevated CO2 and O3, and ambient control in 30 m treatment rings with three replications. Our overall results showed that our three growth parameters including height, diameter and volume were increased by elevated CO2, decreased by elevated O3, and were not significantly different from the ambient control under elevated CO2 + O3. However, there were significant clonal differences in the responses; all five clones exhibited increased growth with elevated CO2, one clone showed an increase with elevated O3, and two clones showed an increase over the control with elevated CO2 + O3, two clones showed a decrease, and one was not significantly different from the control. Notably. there was a significant increase in current terminal shoot dieback with elevated CO2 during the 1999-2000 dormant season. Dieback was especially prominent in two of the five clones, and was attributed to those clones growing longer into the autumnal season where they were subject to frost. Our results show that elevated O3 negates expected positive growth effects of elevated CO2 in Populus tremuloides in the field, and suggest that future climate model predictions should take into account the offsetting effects of elevated O3 on CO2 enrichment when estimating future growth of trembling aspen stands.

AN - 72394855; 11787734 AB - Correct temporal and spatial regulation of apoptosis is critical for normal mammary gland development and lactation. Previous work with a strain of transgenic mice that overexpress des(1-3)hIGF-I during pregnancy and lactation suggested that this growth factor inhibits apoptosis. The hypothesis tested within these studies is that overexpression of des(1-3)hIGF-I within the mammary gland inhibits apoptosis and the expression of apoptosis-associated genes that are known to be activated by the transcription factor AP-1. This inhibition of apoptosis was further posited to predispose the tissue to carcinogenesis. TUNEL analysis of mammary tissue from transgenic mice that overexpress des(1-3)hIGF-I under control of the rat whey acidic protein promoter showed only 25% (P < 0.05) of the number of apoptotic cells found in nontransgenic mice at the same stage of lactation. Northern analysis of RNA from these animals showed a 75% (P = 0.08) reduction in c-Jun mRNA abundance. Histological analysis of mammary tissue from nonlactating multiparous WAP-DES mice ranging in age from 13 to 25 months showed a variety of hyperplastic lesions. These lesions aberrantly expressed the transgene. At 23 months of age 50% of the transgenic mice within this study developed adenocarcinomas. These results support the conclusion that inhibition of apoptosis within the mammary gland by IGF-I involves decreased activity of AP-1 and predisposes the tissue to tumors.

AN - 72320779; 11732201 AB - Cotton fibers are often utilized as a model system to investigate cellulose biosynthesis and cell wall elongation. In this study, we grew cotton fibers in vitro, with ovules dissected at day zero post anthesis as the explant source, in the presence of three herbicides that inhibit cellulose biosynthesis. Cultures were sampled for electron microscopy and immunocytochemistry 1-2 days after beginning the treatments. After dichlobenil treatment, the fibers were much shorter than the controls and assumed a variety of abnormal shapes, from shortened versions of the control fiber to nearly spherical. The inner layers of the fiber wall often contained juxtaposed electron-translucent and -transparent areas; this layer reacted strongly with antibodies to callose. Cellulase-gold labeling in these newly developed fibers grown in the presence of dichlobenil was present at only about 3% of the control labeling. After treatment with either isoxaben or flupoxam, the fibers assumed spherical shapes and frequently (more than 60% of fibers) exhibited a new cell plate within the fiber, indicating that cell division had occurred, a process that rarely occurred in the controls. Unlike the dichlobenil-treated fibers, fibers grown in the presence of isoxaben or flupoxam contained an extensive accumulation of chiefly deesterified pectins, replacing the entire wall with an elaborated version of the pectin sheath found in control cotton fibers. These data indicate that all three herbicides are effective disrupters of cellulose biosynthesis and cause radical changes in cell wall structure and composition. Moreover, these data indicate that the composition of the walls may influence indirectly cell cycle kinetics, keeping these fiber cells in a more meristematic mode.

AN - 72261036; 11697765 AB - The importance of interactive effects, of minerals in general, on nutrient requirements is becoming increasingly recognized. The interaction between iron and zinc has not been as widely investigated. The metabolic interrelationships between dietary iron and zinc have been known for years, but some subtle relationships may have gone unrecognized. Because nutrient interactions are not necessarily linear in nature, it may be inadequate to apply linear statistical models to study the interaction between zinc and iron. In this study, we used traditional as well as a nonlinear approach in analyzing experimental results from groups of rats fed a wide range of dietary zinc and iron. Male weanling Sprague-Dawley rats were used in a 5 x 4 factorially arranged experiment. Dietary variables were iron (as ferric citrate) at 4, 12, 24, 48, or 96 microg Fe/g diet and zinc (as zinc carbonate) at 5, 10, 20, or 40 microg Zn/g diet. After 7 wk, hematological parameters were measured and plasma ceruloplasmin and cholesterol were determined. In addition to interactive effects as shown by analysis of variance, the application of log-linear analysis to the experimental data revealed a far broader range of interactions between dietary iron and zinc. As a result of our experiment and its quantitative analysis, we conclude that the interaction between iron and zinc is nutritionally important and that dietary iron affected the response of many blood parameters to dietary zinc.

AN - 72222257; 11673641 AB - Low dietary copper has been shown to decrease the expression of various protein kinase C (PKC) isozymes and increase the risk of colon cancer development in experimental animals. The purpose of this study was to investigate the relationship between dietary copper and carcinogen administration on PKC isozyme accumulation and aberrant crypt foci (ACF) formation in rats fed 0.9 and 7.7 microg Cu/g diet. After 24 and 31 d on the diets, the rats were injected with either dimethylhydrazine (DMH) (25 mg/kg i.p.) or saline and killed at two time points (2 wk and 8 wk after DMH). Rats fed low dietary copper had significantly lower (p<0.0001) hematocrits, hemoglobin, ceruloplasmin activity and plasma and liver copper concentrations than rats fed adequate dietary copper. Ingestion of low dietary copper significantly (p<0.005) increased the formation of DMH-induced ACF (116.8 vs 59.6). Low dietary copper significantly (p<0.05) decreased the concentration of PKC alpha, delta, and zeta in the colon at 2 wk but not at 8 wk. Thus, changes in PKC isoform protein concentration may be related to increased susceptibility of copper-deficient animals to colon cancer.

AN - 71388609; 15049446 AB - A laboratory model using green pepper disks was developed to investigate the attachment of Salmonella Chester on plant tissue and to evaluate the effectiveness of sanitizer agents in inactivating attached bacteria on fruits. Pepper disks (14 mm in diam, and 3-4 mm in thickness) were immersed in a bacterial suspension containing 1.5 x 107 cfu x mL(-1) of S. Chester for 30 s and subsequently air-dried at room temperature for 10 min. Approximately 30% of the bacteria retained on the disk after immersion were firmly attached and could not be removed by two washes and agitation. A positive correlation was observed between the number of bacteria attached and the concentration of bacteria in the suspension. Population studies and scanning electron microscopic examinations revealed that attachment of S. Chester on pepper disks occurred mainly on the surfaces of injured (cut) tissue but rarely on the unbroken skin. When inoculated disks were treated with 3% to 12% (w/v) of trisodium phosphate (TSP) at pH 12.3 for 5 min, the population of bacteria on the disk was reduced by 10- to 100-fold. A small portion (0.7% to 7.1%) of bacteria attached to the disk were either resistant to or protected from the TSP treatment. When the pH of TSP solution was reduced from 12.3 to 4.5, the effectiveness of TSP in inactivating S. Chester on pepper disks was reduced by 26%. This study shows that surfaces of injured fruit tissue are the principal sites for bacterial attachment, and a small portion of the bacteria attached to the tissue are resistant to the sanitizer treatment. Avoiding mechanical injuries to fresh fruits during and after harvest would reduce the chance of pathogen attachment and contamination on green pepper and fruits of similar nature.

AN - 71290205; 11898346 AB - Seeds of Karwinskia humboldtiana obtained from a 1997 collection in the locality of Villa de Gracía Nuevo (León, Mexico) were contaminated with spores of filamentous fungi, bacteria and yeasts. The concentration of microorganisms in unscarified seeds ranged from 3.0 x 10(3) to 7.5 x 10(3) CFU/g. Predominant were bacterial isolates of the genera Aeromonas sp., Bacillus, and Pseudomonas; from filamentous fungi were identified Alternaria, Aspergillus niger, Cladosporium sp., Fusarium sp., Mucor sp., Penicillium commune, Trichothecium sp.; from yeasts Rhodotorula sp. and Saccharomyces cerevisiae. Seed scarification significantly reduced the microbial contamination. Of the original fungal isolates, only two were identified on scarified seeds, viz. Cladosporium sp. and Saccharomyces cerevisiae; although a relatively high incidence of a unidentifiable of Penicillium sp. was found, the bacterial spectrum was not altered. Treatment of scarified seeds with Vitavax 200 WP and Pomarsol Forte 80 WP (3 mg/g seeds) augmented germination by 10-19% compared to treated unscarified seeds, and by 16-31% compared to untreated unscarified seeds.

AN - 71191989; 11568456 AB - The reduction in incidence of chemically-induced colon cancer by foods high in selenium (Se) was investigated in Fisher-344 rats. The foods used were high-Se broccoli (produced in a greenhouse by addition of selenate to the media surrounding the plant roots) and a processed high-Se wheat product (made by milling high-Se wheat purchased from a seleniferous area). Weanling rats were fed diets containing different amounts of Se from these foods or from selenium salts (selenite and selenate). Early in the experiment the animals were injected with a chemical carcinogen. After 11 weeks on diets animals were killed and the colons examined for preneoplastic lesions (aberrant crypts foci, ACF). ACF were significantly reduced in animals fed supra-nutritional amounts of Se from broccoli, despite the finding that Se from broccoli was poorly bioavailable. Supra-nutritional amounts of Se from high-Se processed wheat also significantly reduced aberrant crypts (AC), although pure selenomethionine, (the predominant chemical form of Se in wheat), did not significantly reduce AC. These results emphasize the need to study Se in food forms, and not extrapolate from previous studies using pure chemical forms in cancer inhibition studies. They also demonstrate that foods with high Se bioavailability are not necessarily the most efficacious for cancer incidence reduction.

AN - 71191046; 11568462 AB - Selenium toxicity is encountered in arid and semi-arid regions of the world with alkaline, seleniferous soils derived from marine sediments. Once present in soils and waters at high concentrations, Se is very complicated and highly expensive to remove with conventional physical and chemical techniques. Phytoremediation is a plant-based technology that is being considered for managing Se in central California soils. The technology involves the use of plants in conjunction with microbial activity associated with the plants to extract, accumulate, and volatilize Se. Once absorbed by plant roots, Se is translocated to the shoot where it may be harvested and removed from the site. Therefore, plant species used for phytoremediation of Se-laden soils may by plant uptake and volatilization minimize the Se load eventually entering agricultural effluent and the harvested crop can be carefully blended with animal forage and fed to animals in Se-deficient areas.

AN - 71165839; 11554582 AB - The use of nontoxigenic strains of Aspergillus flavus and A. parasiticus in biological control effectively reduces aflatoxin in peanuts when conidium- producing inoculum is applied to the soil surface. In this study, the movement of conidia in soil was examined following natural rainfall and controlled precipitation from a sprinkler irrigation system. Conidia of nontoxigenic A. flavus and A. parasiticus remained near the soil surface despite repeated rainfall and varying amounts of applied water from irrigation. In addition, rainfall washed the conidia along the peanut furrows for up to 100 meters downstream from the experimental plot boundary. The dispersal gradient was otherwise very steep upstream along the furrows and in directions perpendicular to the peanut rows. The retention of biocontrol conidia in the upper soil layers is likely important in reducing aflatoxin contamination of peanuts and aerial crops such as corn and cottonseed.

Effects of hydrogen peroxide on glutathione and sphingomyelinase activity in pheochromocytoma PC12 cells: potential relevance to age-related diseases. AN - 71005160; 11459075 AB - The antioxidant and pro-oxidant capacity of catecholamines (CA) and related compounds were analyzed using the oxygen radical absorbance capacity (ORAC) assay. In the assay 2,2'-azobis (2-amidino-propane) dihydrochloride (AAPH), a peroxyl radical generator, ROO*; H2O2-Cu2+, mainly a hydroxyl radical generator, *OH; and Cu2+ a transition metal were used. The antioxidant effect of CA and its related compounds were in the order: neurotransmitters: dopamine (DA), norepinephrine (NE) > metabolites > amino acid precursors as measured by using AAPH. The antioxidant effect of CA and related compounds as measured by using AAPH were linearly correlated with concentration, while the antioxidant effect of CA in scavenging *OH produced by H2O2-Cu2+ increased proportionally to concentration at low concentration, but after reaching a maximum declined with increasing concentration. In the presence of Cu2+, CA acted as pro-oxidant. Glutathione (GSH) acted as a pro-oxidant when H2O2-Cu2+ or when Cu2+ alone was used as an oxidant and showed much higher pro-oxidant effect than DA, which could have relevance in the vulnerability of dopaminergic neurons to oxidative stress in the aging and aging related diseases. The antioxidant capacity of CA and many related compounds seems to be correlated with the numbers of hydroxyl groups and their position on the benzoic ring. The O-methylation and sulfate conjugation of the hydroxyl substitution inactivates both the antioxidant and pro-oxidant activities of CA. Our results show that oxidative stress induced by low (5 microM) or high (300 microM) doses H2O2 in pheochromocytoma PC12 cells significantly up-regulate the activity of Mg-dependent neutral sphingomyelinase (Sase), and significantly decreased GSH.

AN - 71001231; 11450854 AB - The presence of E. coli O157:H7 in cattle illustrates the complex, interrelated nature of the environment, livestock production practices, food safety, and the science of microbiology, particularly microbial ecology. Enterohemorrhagic E. coli, including E. coli O157:H7, can cause severe human diseases that can be debilitating and life threatening. Cattle are currently considered to be the definitive source for E. coli O157:H7 in the food supply, but this view may be simplistic and incomplete. E. coli O157:H7, appears widespread among U.S. cattle herds, while individual animal prevalence is low and transient. Most individual animals appear to be a transient reservoir for E. coli O157:H7 although the issue of carrier animals still remains unresolved. Epidemiological studies of the cattle production system have not clearly identified risk factors or management practices that affect E. coli O157:H7 prevalence in cattle feces. The problem of E. coli O157:H7 increases during the summer and fall months, but the environmental factors that contribute to this increase are poorly understood. Possible environmental factors that may influence E. coli O157:H7 shedding in cattle include livestock feed and waste handling practices as well as insects and microbial interactions in soil and water. Studies of E. coli O157:H7 ecology in cattle and the environment have been limited, but they suggest that a consideration of other independent, environmental sources of this microbe seems appropriate. The natural ecology of cholera may serve as a useful environmental model for pursuing additional environmental research on the occurrence and transmission of E. coli O157:H7 in nature.

AN - 70984941; 11448039 AB - An ethyl methanesulfonate-induced mitotic mutant of durum wheat (Triticum turgidum L. var. durum; 2n = 4x = 28) was found. We have characterized the mutant to determine the mechanism of abnormal cell division and to test for temperature effects on abnormal cell division. Stained root-tip meristems and pollen mother cells were studied with brightfield, phase contrast, and immunofluorescence microscopy. Abnormal cells included metaphase cells with a multiple of the normal complement (8x = 56, or 16x = 112), multinucleate cells, 4C, 8C, or 16C mononucleate cells, and cells exhibiting incomplete cytokinesis. The mutant had three classes of pollen mother cells: euploid with normal bivalent pairing, multiploid with bivalent pairing, and multiploid with multivalent pairing. Preprophase bands and spindles were normal in mononucleate cells. Some cells had asymmetrical phragmoplasts and phragmoplast dismantling that produced incomplete cytokinesis. Failure of cytokinesis followed by nuclear fusion were the mechanisms of abnormal cell division. To test for temperature sensitivity of the mutant, seedlings were germinated under six different temperature regimes. As germination temperature increased, the frequency of abnormal cells increased. When the mutant was crossed as the female with durum wheat, 3% of hybrids were hexaploid, indicating that functional-unreduced gametes had formed in megaspores.

AN - 70909072; 11382060 AB - This study was replicated at two locations in the mountains of central Utah. In 1997, ten uniform plants of tall larkspur (Delphinium barbeyi) in the early bud stage (40 cm in height) were selected at each site and clipped at 5 cm above soil level. In 1998, one stalk from each plant was harvested on a weekly basis; in 1999, one stalk was harvested at four times during its phenological development. Toxic and total alkaloid concentrations were measured and alkaloid pools in the entire stalk were calculated. Clipping reduced stalk height to less than 50 cm in 1998 and 65 cm in 1999, compared to over 100 cm in unclipped control plants. Alkaloid concentration was similar to control plants, but toxic alkaloid pools were 70% lower than control plants, because of the reduction in biomass of the stalks. Clipping reduced subsequent vigor and the amount of toxic and total alkaloids in tall larkspur.

AN - 70836108; 11352029 AB - Cerro Negro bitumen, separated from an Orimulsion sample, was incubated for up to 120 days with sediments collected at a petroleum-impacted site in Tampa Bay, Florida. Biodegradation conditions were optimized by increasing bitumen surface area, continuous agitation on a shaker apparatus, use of a complete growth medium, and maintenance at 37 degrees C. Aerobic degradation conditions were promoted by maintaining sediment contact with the laboratory atmosphere. Bitumen recovered in solvent extracts when compared to autoclaved controls decreased by up to 40% during the first 56 days. There was no detectable change after this. Molasses addition and use of a culture enriched from the sediments did not change the extent or rate of decrease in bitumen recovery. Chemical fractionation of bitumen control and degraded bitumen showed that aromatic and aliphatic fractions were depleted by approximately equals 50%. Accumulation of polars was observed; however, the apparent increase was relatively small when compared to the mass loss of the other fractions. Selected biomarker ratios were not affected by incubation indicating their utility for fingerprinting the source bitumen in environmental samples. PAH distribution in the aromatic fraction favored the higher alkyl-homologues with the relative degree of alkylation increasing as the mass of bitumen recovered decreased with degradation. The study showed that up to 40% of the bitumen was bioaccessible and that bioremediation may be a treatment option for sediments contaminated with bitumen by an Orimulsion spill.

AN - 70655993; 11208727 AB - Long-term and excessive ethanol intake results in decreased plasma and hepatic levels of retinoic acid (RA), the most active derivative of vitamin A. The decrease of RA by ethanol treatment has been proposed to be a cytochrome P450 enzyme (CYP)-dependent process. However, the role of the major ethanol-induced CYP, CYP2E1, in the metabolism of RA has not been defined. In vitro incubations of RA with microsomal fractions of liver tissue containing CYPs from either ethanol-exposed or non-ethanol-exposed rats were carried out using chemical inhibitors and antibodies against various CYPs. In vivo, both ethanol-exposed and non-ethanol-exposed rats were treated with or without chlormethiazole, a specific CYP2E1 inhibitor, for 1 month. RA and its catabolic metabolites were analyzed by high-performance liquid chromatography and spectral analysis. Incubation of RA with the liver microsomal fraction from ethanol-exposed rats resulted in greater disappearance of RA and increased appearance of 18-hydroxy-RA and 4-oxo-RA compared with control rat liver microsomal fractions. The enhancement of RA catabolism by ethanol was inhibited by both CYP2E1 antibody and specific inhibitors (allyl sulfide and chlormethiazole) in a dose-dependent fashion, whereas the metabolism of RA into polar metabolites was abolished completely by nonspecific CYP inhibitors (disulfiram and liarozole). Furthermore, treatment with chlormethiazole in ethanol-fed rats in vivo restored both hepatic and plasma RA concentrations to normal levels. Ethanol-induced CYP2E1 plays a major role in the degradation of RA, which may provide a possible biochemical mechanism for chronic and excessive ethanol intake as a risk for both hepatic and extrahepatic cell proliferation and carcinogenesis.

AN - 70627986; 11164287 AB - The beta-amyloid hypothesis of Alzheimer's Disease (AD) has dominated the thinking and research in this area for over a decade and a half. While there has been a great deal of effort in attempting to prove its centrality in this devastating disease, and while an enormous amount has been learned about its properties (e.g., putative toxicity, processing and signaling), Abeta has not proven to be both necessary and sufficient for the development, neurotoxicity, and cognitive deficits associated with this disease. Instead, the few treatments that are available have emerged from aging research and are primarily directed toward modification of acetylcholine levels. Clearly, it is time to rethink this position and to propose instead that future approaches should focus upon altering the age-related sensitivity of the neuronal environment to insults involving such factors as inflammation and oxidative stress. In other words "solve the problems of aging and by extension those of AD will also be reduced." This review is being submitted as a rather Lutherian attempt to "nail an alternative thesis" to the gate of the Church of the Holy Amyloid to open its doors to the idea that aging is the most pervasive element in this disease and Abeta is merely one of the planets.

AN - 70597302; 11215655 AB - Manure use on cropland has raised concern about nutrient contamination of surface and ground waters. Warm-season perennial grasses may be useful in filter strips to trap manure nutrients and as biomass feedstock for nutrient removal. We explored the use of 'Alamo' switchgrass (Panicum virgatum L.) in a biomass production-filter strip system treated with dairy manure. We measured changes in extractable P in the soil, NO3 -N in soil water, and changes in total reactive P and chemical oxygen demand (COD) of runoff water before and after a switchgrass filter strip. Five rates of dairy manure (target rates of 0, 50, 100, 150, and 200 kg N ha(-1) from solid manure in 1995; 0, 75, 150, 300, and 600 kg N ha(-1) from lagoon effluent in 1996 and 1997) were surface-applied to field plots of switchgrass (5.2 by 16.4 m) with a 5.2- by 16.4-m switchgrass filter strip below the manured area. Yield of switchgrass from the manured area increased linearly with increasing manure rate in each year. Soil water samples collected at 46 or 91 cm below the soil surface on 30 dates indicated < 3 mg L(-1) of NO3-N in all plots. Concentrations of total reactive P in surface runoff water were reduced an average of 47% for the 150 kg N rate and 76% for the 600 kg N rate in 1996 and 1997 after passing through the strip. Manure could effectively substitute for inorganic fertilizer in switchgrass biomass production with dual use of the switchgrass as a vegetative filter strip.

AN - 70596843; 11202716 AB - To provide an understanding of arsenic (As) and mercury (Hg) concentrations in soil, sediment, water, and fish tissues, samples were collected from a Mississippi River alluvial floodplain located in northwest Mississippi. As concentrations increased approximately an order of magnitude from water (5.12 micrograms/l) to fish tissues (36.99 micrograms/kg) and an additional two orders of magnitude in soils, lake sediments, and wetland sediments (5728, 5614, and 6746 micrograms/kg), respectively. Average Hg concentrations in water, soils, lake sediments, and fish were 2.16 micrograms/l, 55.1, 14.5 and 125 micrograms/kg, respectively. As and Hg concentrations were within published ranges for uncontaminated soil, water, and sediments. As concentrations represented a low risk. Hg concentrations were also low but showed a greater tendency to concentrate in fish tissue. The dominant mode of entry of these materials into aquatic systems is through storm-generated runoff. Since both metals accompany sediments, agricultural conservation practices such as reduced tillage, buffer riparian strips, and bordering sediment ponds or drainage wetlands will minimize watershed input to aquatic systems.

AN - 70594670; 11215664 AB - By 19%, standard remediation techniques had significantly reduced the concentration of nitrate nitrogen (NO3- -N) in local ground water at the site of a 1989 anhydrous ammonia spill, but NO3- -N concentrations in portions of the site still exceeded the public drinking water standard. Our objective was to determine whether local soil and ground water quality could be improved with alfalfa (Medicago sativa L.). A 3-yr study was conducted in replicated plots (24 by 30 m) located hydrologically upgradient of the ground water under the spill site. Three alfalfa entries ['Agate', Ineffective Agate (a non-N2-fixing elite germplasm similar to Agate), and MWNC-4 (an experimental germplasm)] were seeded in the spring of 1996. Corn (Zea mays L.) or wheat (Triticum aestivum L.) was seeded adjacent to the alfalfa each year. Crops were irrigated with N-containing ground water to meet water demand. During the 3-yr period, about 540 kg of inorganic N was removed from the aquifer through irrigation of 4.9 million L water. Cumulative N removal from the site over 3 yr was 972 kg N ha(-1) in Ineffective Agate alfalfa hay, compared with 287 kg N ha(-1) for the annual cereal grain. Soil solution NO3- concentrations were reduced to low and stable levels by alfalfa, but were more variable under the annual crops. Ground water quality improved, as evidenced by irrigation water N concentration. We do not know how much N was removed by the N2-fixing alfalfas, but it appears that either fixing or non-N2-fixing alfalfa will effectively remove inorganic N from N-affected sites.

Identification and characterization of Al(3+)-induced anion channels. AN - 70582677; 11154337 AB - The presence of Al(3+) in the rhizosphere induces citrate efflux from the root apex of the Al-tolerant maize (Zea mays) hybrid South American 3, consequently chelating and reducing the activity of toxic Al(3+) at the root surface. Because citrate is released from root apical cells as the deprotonated anion, we used the patch-clamp technique in protoplasts isolated from the terminal 5 mm of the root to study the plasma membrane ion transporters that could be involved in Al-tolerance and Al-toxicity responses. Acidification of the extracellular environment stimulated inward K(+) currents while inhibiting outward K(+) currents. Addition of extracellular Al(3+) inhibited the remaining K(+) outward currents, blocked the K(+) inward current, and caused the activation of an inward Cl(-) current (anion efflux). Studies with excised membrane patches revealed the existence of Al-dependent anion channels, which were highly selective for anions over cations. Our success in activating this channel with extracellular Al(3+) in membrane patches excised prior to any Al(3+) exposure indicates that the machinery required for Al(3+) activation of this channel, and consequently the whole root Al(3+) response, is localized to the root-cell plasma membrane. This Al(3+)-activated anion channel may also be permeable to organic acids, thus mediating the Al-tolerance response (i.e. Al-induced organic acid exudation) observed in intact maize root apices.

In a between-groups designed experiment in El Salvador, longer, more detailed questions on consumption result in an estimate of mean, household consumption that is 31% greater than the estimate derived from a condensed version of the questionnaire. The distribution of household consumption from the long questionnaire first-order stochastically dominates the distribution from the short questionnaire over 96% of the range of the distribution. This difference in estimated consumption results in a measure of absolute, severe poverty from the short questionnaire that is 46% greater than the estimate derived from the long questionnaire. In contrast, the level of relative poverty is unaffected by the changes in questionnaire design. An implication of this paper is that modifications over time to questionnaires will result in spurious estimates of change in consumption & absolute poverty levels. 7 Tables, 3 Figures, 1 Appendix, 43 References.

Large multinationals have moved to take advantage of these developments with the construction of agri-food chains. These chains are being facilitated via various mergers, acquisitions, & alliances, with the power, & deepening power of such deep-pocket organizations as Cargill, ADM, & ConAgra. Cooperatives have been integrated into these chains for their core competencies, generally for their supply functions, & capacity to handle primary commodities. These direct links to the farmers serve as markets for biotechnology innovations, & as a source of raw material for later processing. Agricultural cooperatives in general are not well suited to compete with these giants, given that they are highly specialized at the first handler level. However, some cooperatives are able to enter the competition along the lines of multinationals competition, ie, nonprice competition in product differentiation, branding, advertising, research, & capacity expansion. Farmland, Gold Kist, AGP, Land O'Lakes, & Growmark are examples. The cost of these positionings is to shift these organizations toward positions that are characteristically less cooperative, & more bureaucratic, & more top down, though likely more efficient, & with greater market penetration. 1 Table, 4 Figures, 29 References.

The concept of autonomy is briefly characterized, including various partial forms of autonomy according to the political & legal aspects, spatial aspects & formation (top-down & bottom-up). At the local level, besides two main forms of autonomy -- spatial & personal, I outline more holistic "extensive local autonomy," that overcomes traditional meanings of autonomy. More attention is paid to prevailing understanding of local autonomy -- as autonomy of local government. In this case, the important role of decentralization, relation between autonomy & self-government, as well as relations to the other levels of government & lines of power (executive, legislative, & judiciary) are emphasized. Besides crucial political autonomy, I discuss fiscal autonomy & various other possibilities for functional autonomy. Potential of autonomous institutions based on personal autonomy should not be underestimated also at the local level. The most known concrete forms of autonomy applied in regulations of inter-ethnic relations & minority needs satisfaction are addressed. They cover autonomy of parallel local governments, autonomy of sub-local governments, autonomy of functional local governments, as well as informal bottom-up cases based on personal & institutional autonomy, as are informal autonomous parallel governments, informal sub-local & functional autonomies. Their main features, advantages, as well as risks in practical application are discussed, including some normative aspects. I reveal high potential of various autonomous structures at the local level. Nevertheless, I recommend applying them as a responsible local autonomy. It should be arranged by combination of various institutions with autonomous position, but circumscribed by guarantees for civil rights & democracy expressed in constitution, legislature, & protected by independent courts. 1 Figure, 41 References.

Re-establishing grass on CL generally increases soil organic matter, which improves soil conditions. This study was conducted to determine effects of land uses [CL, NGL, and Conservation Reserve Program (CRP) land (CRPL)] on STCC (mainly organic C), aggregation, bulk density, and penetration resistance. Cropland, NGL, and CRPL sites were sampled at 11 locations in the southern Great Plains. Penetration resistance was measured at the sites. Mean STCC at 0- to 2-cm depths were lowest on CL, intermediate on CRPL, and highest on NGL (2.7, 5.4, and 7.6 Mg ha (super -1) , respectively). Trends were the same at greater depths. Re-establishing grass on CL resulted in increased STCC, but achieving contents comparable to those on NGL will require more than 10 yr. Water-stable aggregate mean weight diameter and water-stability of 1- to 2-mm aggregates were positively related and percentage of <0.25-mm water-stable aggregates was negatively related to STCC. The aggregate results indicate the importance of high STCC for maintaining conditions conducive to using precipitation and irrigation water efficiently. Land use affected bulk density and penetration resistance slightly, but relationships between them were not significant. Few relationships between soil water content and penetration resistance were significant, probably because of widely diverse conditions involved. Establishing grass on CL reverses soil degradation, but crop production is lost. Hence, practices that minimize STCC losses should be used to minimize CL degradation.

In the USA, an accurate and defensible estimate of C storage in cropland soils is critical for the development of effective agricultural and environmental policies and strategies. Furthermore, such estimates are needed to fulfill U.S. obligations under the Framework Convention on Climate Change (FCCC). Our research focuses on using a balance sheet approach to estimate net changes in soil C storage in U.S. croplands for the FCCC baseline year (1990). Using input data from a number of sources to obtain information on land use, soils, crops, tillage practices, and climate, we developed a series of spreadsheet models that estimate changes in C storage in cropland soils. Preliminary estimates indicate that changes in land use and management have resulted in mineral soils being a net sink of 11.31 million metric tons (MMT) of C yr (super -1) . Organic soils remain a source of atmospheric C, with emissions estimated at 6.03 MMT of C yr (super -1) . Mineral soils in the Warm Temperate, Moist climatic region of the eastern USA are sequestering the most C, while organic soils in the Sub-Tropical, Moist region have the largest total emissions. Additional modeling is being conducted to obtain estimates of the year-to-year changes in C storage, as well as the potential for increased C sequestration. Strengths and limitations of the approach are discussed.

They show an increase of radiocarbon age from mainly modern-3000 BP in 0-100 cm layer up to 10,000 BP at a depth 100-200 cm. Older dates reflect the age of parent material. The inversion of (super 14) C dates seems to be a frequent phenomenon in Vertisols. A series of new dates of Vertisols from gilgai microhigh, microslope and microlow in the North Caucasus was done in order to understand the nature of this inversion. (super 14) C age in the gilgai soil complex ranges from 70+ or -45 BP in the microlow to 5610+ or -180 BP in the microhigh. A trend of similar depths being younger in the microslope and microlow was found. We explain this by intensive humus rejuvenation in the microlows due to water downward flow. The older date in the microhigh represents the old humus horizon sheared laterally close to the surface and preserved by impermeable water regime. We explain inversions of (super 14) C age-depth curves by the sampling procedures. In a narrow pit, genetically different parts of former gilgai could easily be as a genetically uniform soil profile. Because of this strong microvariability, Vertisols require sampling in a trench accounting for gilgai elements, even when gilgai are not obvious.

The management response was to move the gravel deposits from in the channel and create piled gravel levees along the stream. Similar gravel removal projects were completed after floods in 1956, 1965, 1974 and 1981. This repeated gravel removal and channel widening had left an incised, broad, "U" shaped channel with two different bedload transport regimes. During a channel forming flow of approximately 900 ft (super 3) s (super -1) (4.3 csm, approximately a 1.8 year return interval) the channel generated a relatively low tractive stress of approximately 1.5 lb. ft (super -2) and could not transport the bedload coming into the reach. An opposite response was displayed during less frequent events. Due to the levees along the channel, a flow of 3,200 ft (super 3) s (super -1) (15 csm, approximately a ten year recurrence interval) generated shear stress in excess of 5.4 lb. ft (super -2) , enough to mobilize a majority of particles in the bed and banks. A design was completed to narrow and deepen the channel during frequently recurring floods, and to excavate a floodplain accessible to flows during larger floods. This design increased the reach-averaged tractive stress approximately 15% during the channel forming flow and decreased the reach-averaged tractive stress 18% during higher, less frequent flood flows. Integrated with the physical channel manipulation was the use of vegetative plantings to change the existing uniform flow patterns to a more typical and more variable pattern of pools (scour areas) and riffles (deposition areas). The confluence of a small tributary with a mass-failure dominated sediment regime as well as an undersized bridge provided challenges in the design. The design was installed on over 6,000 feet of the Big Canyon Creek channel in late 1999 at a total cost of approximately $200,000. The expected impact on channel processes from implementation of the design are to move bedload through the channel system more consistently. This consistent movement will prevent large areas of aggradation during years of smaller floods, and oppositely, large scale channel adjustments during years with larger floods. The overall result will be a stream with more predictable characteristics upon which to base management strategies, and also a stream with more diverse habitat for fish and wildlife. Preliminary measurements and observations indicate the modifications to the channel are having the desired impacts.

Native mature oak and pine trees had fallen off the banks, or were at risk from undermining and root exposure. Two miles of creek were stabilized through construction of low visibility chute grade stabilization structures, raising of the creek bed, and shaping banks. This created stable conditions for revegetation, habitat establishment, and minimal future maintenance. While the presence of high-valued vineyards adjacent to the creek limited opportunities for geomorphically-based channel restoration, the Marre Canyon Creek project is notable for its balance between creek preservation and intensive farming practices. Critical to the project construction was the communication between the owner, inspectors, and contractor for the purposes of preserving the natural creek meanders and the riparian tree cover.

In order for the results of this tool to attain public, environmental, and regulatory acceptability, these and other special interest groups should be encouraged to participate in data acquisition and analyses. The proposed tool defined here as a Dynamic Sediment Modeling and Analysis Process (DSMAP) will provide methodology for determining quantities of stream sand/gravel that can be mined without disrupting streambed stability. It will allow for sediment production predictions, as well as the potential for adverse impacts from sediment mining, based on current and proposed land use and conservation (or management) practices. End products will include sediment budgets and streambed profiles (1000 feet) of selected streams, showing either aggradation (streambed deposition) or degradation (channel erosion or incision). The end product should allow the county, other interested parties, and representatives of the sand/gravel mining industry to agree to rates of sand/gravel mining at specific locations that will minimize the risk of adverse impacts to the environment such as degradation at bridge footings, etc. The models AnnAGNPS (Darden et Herring 1998) and CONCEPTS (Langendoen 2000) will be linked and their outputs linked to Sediment Budget spreadsheets.

Extracted glutelin was hydrolyzed with Pronase E, a bacterial protease, and the functional properties of hydrolysates were evaluated. Nitrogen solubility of pronase-treated glutelin protein increased from pH 2 to pH 12. Similarly, foaming and emulsion properties of hydrolyzed protein also showed improved characteristics. The emulsion activity, expressed as the turbidity of diluted emulsions, was significantly greater (P<=0.05) for hydrolyzed samples. However, turbidity for all samples decreased with increased homogenization time, indicating a decrease in the volume of dispersed oil. There were significant changes in apparent viscosity as a function of shear rate, with viscosity decreasing with increasing shear rate. The viscosity of dispersions of all hydrolyzed samples was significantly lower than that of the native sample at all shear rates tested. Enzymatic hydrolysis of rice endosperm storage glutelin proteins appeared to improve the functional characteristics of the hydrolyzed proteins.

However, solids removal prior to wetland treatment is essential for long-term functionality. Plants are an integral part of wetlands; cattails and bulrushes are commonly used in constructed wetlands for nutrient uptake, surface area, and oxygen transport to sediment. Improved oxidation and nitrification may also be obtained by the use of the open water of marsh-pond-marsh designed wetlands. Wetlands normally have sufficient denitrifying population to produce enzymes, carbon to provide microbial energy, and anaerobic conditions to promote denitrification. However, the anaerobic conditions of wetland sediments limit the rate of nitrification. Thus, denitrification of animal wastewaters in wetlands is generally nitrate-limited. Wetlands are also helpful in reducing pathogen microorganisms. On the other hand, phosphorus removal is somewhat limited by the anaerobic conditions of wetlands. Therefore, when very high mass removals of nitrogen and phosphorus are required, pre- or in-wetland procedures that promote oxidation are needed to increase treatment efficiency. Such procedures offer potential for enhanced constructed wetland treatment of animal wastewater. JF - Water Science & Technology AU - Hunt, P G AU - Poach, M E AD - USDA-ARS, 2611 W.

However, in many applications it would be beneficial to remove much or all of the CCA from the wood prior to composite production. This paper evaluates the effect of remediation processes, namely oxalic acid (OA) extraction and Bacillus licheniformis fermentation, on leaching of copper, chromium, and arsenic from particleboard made from remediated wood particles and also investigates decay resistance of the particleboard. Oxalic acid extraction and bioremediation by B. licheniformis affected the chemical properties of wood particles and significantly increased leaching of elements from CCA-treated wood particles. The particleboard containing OA-extracted and bioremediated particles showed generally high leaching losses of remaining elements. Exposure of particleboards to decay fungi in soil block tests indicated that boards containing CCA-treated particles were most resistant to fungal degradation. Also, for a given board type, Gloeophyllum trabeum resulted in greater weight losses than Postia placenta and Tramets versicolor after 12-week exposure. We concluded that bioremediation of CCA-treated wood is a promising method of safely reusing treated fiber, although chemical extraction diminished the properties of composites prepared from this material.

The small CTL harvester produced 11.08 m3 [391.4 ft3] per productive machine hour (PMH) compared to 14.83 m3 [523.80 ft3] per PMH for the large harvester. The impact of average tree size (volume) on cost was substantial but similar for both CTL systems. At a fixed stump-to-landing logging cost of about $14.12/m3 or [$0.40/ft3], the BEP tree size was 0.14 m3 [5.0 ft3] for the small harvester and 0.26 m3 [9.33 ft3] for the large system at the 85 percent MUR. At an MUR of 70 and 85 percent, the processing cost for trees that averaged 0.08 m3 [3.0ft3] was $22.19 and $18.28/m3 [$0.6285 and $0.5176/ft3], respectively, for the small CTL harvester. Results were similar for the large harvester. Either CTL system would be effective in helping managers meet forest management goals in eastern hardwood stands.

An example is the Water Content Reflectometer (WCR; Campbell Scientific, Logan, UT), which is much less expensive than TDR and is used widely, although little has been published concerning its applicability to soil water content monitoring. super(1) The primary objectives of this study were to determine the WCR soil water calibration for different soils and to investigate how it is affected by changing temperature. We found the individual sensors to be very precise (CV [<=] 0.05) under the controlled laboratory conditions of this study. Variability among sensors, determined in air and ethanol, indicated significant sensor differences that were largely accounted for with a simple additive correction. Sensor soil water calibration was investigated in four soils under varying water contents across a 40 degree C temperature range. We found that (i) soil water calibration was significantly different for each soil tested, (ii) there was a significant temperature response for all soils, and (iii) the effect of temperature varied with soil water content and soil type. Both the soil type and temperature sensitivities we observed were probably due to the relatively high electrical conductivity (EC) of the soils tested.

Biodegradation conditions were optimized by increasing bitumen surface area, continuous agitation on a shaker apparatus, use of a complete growth medium, and maintenance at 37 degree C. Aerobic degradation conditions were promoted by maintaining sediment contact with the laboratory atmosphere. Bitumen recovered in solvent extracts when compared to autoclaved controls decreased by up to 40% during the first 56 days. There was no detectable change after this. Molasses addition and use of a culture enriched from the sediments did not change the extent or rate of decrease in bitumen recovery. Chemical fractionation of bitumen control and degraded bitumen showed that aromatic and aliphatic fractions were depleted by approximately 50%. Accumulation of polars was observed; however, the apparent increase was relatively small when compared to the mass loss of the other fractions. Selected biomarker ratios were not affected by incubation indicating their utility for fingerprinting the source bitumen in environmental samples. PAH distribution in the aromatic fraction favored the higher alkyl-homologues with the relative degree of alkylation increasing as the mass of bitumen recovered decreased with degradation. The study showed that up to 40% of the bitumen was bioaccessible and that bioremediation may be a treatment option for sediments contaminated with bitumen by an Orimulsion spill.

Trees survive fire exposure by: (1) avoidance of injury through constitutive protection and (2) induced defense. Induced defenses include (a) compartmentalization processes that resist the spread of injury and infection and (b) closure processes that restore the continuity of the vascular cambium after fire injury. Induced defenses are non-specific and are similar for fire and mechanical injury. Dissection of central hardwood species in a prescribed fire treatment area in southeastern Ohio provided an opportunity to place features seen in dendrochronological samples into their biological context. Terms for these features are proposed and further discussion is solicited.

We examined 138 trees from which fire-scarred partial cross sections had been removed five to six years earlier, and 386 similarly sized, unsampled neighbor trees, from 78 plots distributed over about 5,000 ha. Mortality was low for both groups. Although mortality was significantly higher for the sectioned trees than their neighbors (8% versus 1%), removing a partial section did not appear to increase a tree's susceptibility to death from factors such as wind or insect activity. Specifically, the few sectioned stems that broke did so well above sampling height. Most sectioned trees (79%) had evidence of insect activity in 1994/95, while only an additional 5% had such evidence in 2000. Mortality among sectioned trees in this study was low probably because we removed relatively small sections, averaging 7 cm thick and 8% of the tree's cross-sectional area, from large trees of a species with effective, resin-based defenses against insects and pathogens. Sampling live ponderosa pine trees appears to be a non-lethal method of obtaining information on past fire regimes in this region because it only infrequently led to their death in the early years after sampling.

At the same time, we may suppose that the current way of management in the landscape leading to environmental degradation and to the decrease in natural resources can hardly be a basis for sustainable economic development. In the Slovak conditions, mountain and submountain landscape ecosystems provide more cases of unsuitable management with natural resources. Regards rural areas, there exists a significant interrelation between economic activities and the quality of the environment. This interrelation should be reflected also with the creation of plans for the development of countryside. As an example of the interrelation between the development of the country and the creation of plans we used a concrete model territory of the Sobotiste which is a wonderful example of the white-carpatian "kopanitsee" settlement.

Since the early 1990s ozone injury symptoms have been observed on vegetation indicating that the pollutant poses a threat to forests and other ecosystems of the Carpathian Mountains. A new study sponsored by the USDA Forest Service International Programs has been initiated to characterize air pollution distribution and its potential effects on vegetation diversity in the Retezat National Park, Romania. Specific objectives for the study are: (a) characterize spatial and temporal distribution of ozone, sulfur dioxide, ammonia and nitrogen dioxide, (b) evaluate incidence and severity of air pollution injury to vegetation, (c) select native indicators of air pollutants with a special emphasis on ozone, (d) evaluate effects of ozone and other pollutants on forest health and biodiversity, and (e) evaluate effects of various land management practices on mountain ecosystems.

Cell lines from Spodoptera frugiperda (IPLB-Sf21AE), Lymantria dispar (IPLB-LdEIta), and Heliothis virescens (IPLB-HvE6s) in 96-well tissue culture plates were each infected with dilutions of extra cellular virus suspensions of the Autographa californica nucleopolyhedrovirus (AcMNPV). In addition, the L. dispar and H. virescens cells were also infected with L. dispar nucleopolyhedrovirus, and Helicoverpa zea nucleopolyhedrovirus, respectively. Each cell/virus combination was incubated at three temperatures: 22, 27 and 32 degree C and wells were scored for positive infection (presence of occlusion bodies in cell nuclei) at 2 to 4 day intervals for up to 4 weeks. The resulting data were analyzed by the Spearman-Kaerber method, providing virus titers for each combination of virus, cell line, and temperature. The results were categorized by accuracy (assuming the highest titer achieved was the most accurate) and by rapidity of maximum titer. AcMNPV reached the highest titer in each line at 22 degree C although equivalent titers were reached with both AcMNPV and HzSNPV in the HvE6a line at all three temperatures. This line actually reported about 100-fold less AcMNPV than the other two lines with the same virus sample. Alternatively, the Sf21AE and LdEIta lines reached 10-fold higher titers at the lowest temperature as compared with the higher temperatures, although also at a slower rate.

AN - 1859395097; 12639287 AB - Freeze-dried fruits of two strawberry cultivars, Sweet Charlie and Carlsbad, and two blueberry cultivars, Tifblue and Premier were sequentially extracted with hexane, 50% hexane/ethyl acetate, ethyl acetate, ethanol, and 70% acetone/water at ambient temperature. Each extract was tested separately for in vitro anticancer activity on cervical and breast cancer cell lines. Ethanol extracts from all four fruits strongly inhibited CaSki and SiHa cervical cancer cell lines and MCF-7 and T47-D breast cancer cell lines. An unfractionated aqueous extract of raspberry and the ethanol extract of Premier blueberry significantly inhibited mutagenesis by both direct-acting and metabolically activated carcinogens.

Unlike most invasive species, C. orbiculatus exhibits a 'sit and wait' strategy by establishing and persisting indefinitely in undisturbed, closed canopy forest and responding to canopy disturbance with rapid growth, often overtopping trees. We compared fruit fates of C. orbiculatus and native American holly (Ilex opaca). We also explored mechanisms for this 'sit and wait' invasion strategy by testing the effect of C. orbiculatus fruit crop density on removal rates and by examining the influence of seed treatment and light intensity on seed germination and seedling growth. More C. orbiculatus than I. opaca fruits became damaged, and damage occurred earlier. More fruit fell from C. orbiculatus than I. opaca, but removal rates by frugivores did not differ (76.0 plus or minus 4.2% vs 87.5 plus or minus 3.7%, respectively). Density (number of fruits in a patch) of C. orbiculatus did not influence removal rates. Scarification (bird-ingestion) of C. orbiculatus seed delayed germination but seeds germinated in similar proportion to manually defleshed seeds (sown either singly or all seeds from a fruit). Germination of seeds within intact fruits was inhibited and delayed compared to other treatments. Seed treatment did not affect seedling growth. The proportion of seeds germinating and time until germination was similar among five light intensity levels, ranging from full sun to closed-canopy. Seedlings in >70% photosynthetically active radiation (PAR) had more leaves, heavier shoots, and longer, heavier roots than seedlings at lower PAR levels. Results show that most (>75%) C. orbiculatus seeds are dispersed, seedlings can establish in dense shade, and plants grow rapidly when exposed to high light conditions. Control strategies for this highly invasive species should likely focus on minimizing seed dispersal by vertebrates.

We evaluated effectiveness of flashing lights combined with mirrors, and mirrors alone, as deterrents for starlings nesting in starling nest boxes in northern Ohio, 1998-2000. Each year, 100 nest boxes attached to utility poles were randomly assigned equally among 4 treatments (including untreated boxes): 1998 - mirrored (internally placed on the back and 2 side walls of nest boxes), mirrored with red-flashing lights, and mirrored with green-flashing lights; 1999 - convex mirror above entrance hole, convex mirror at back of nest box, and flat mirror at back of nest box; 2000 - mirrors on 3 sides with exposed surface areas of 263 cm super(2), 527 cm super(2), or 790 cm super(2). Starlings nested in 67% (1998) and 78% (1999 and 2000) of the nest boxes. In 1998, boxes within the 3 treatments with mirrors, regardless of lights, had fewer nests and fewer nests with eggs, nestlings, or fledglings than did control boxes (P less than or equal to 0.002). Boxes with mirrors and lights had fewer (P0.25) among the 4 treatments in proportion of nest boxes with starling nests, eggs, nestlings, and young fledged. However, in 2000, boxes with complete mirror coverage did show the lowest occupancy rate of the 4 treatments. Mean dates of first egg, clutch size, number of nestlings, and number of fledglings/nest also were similar (P>0.06) among treatments. We conclude that mirrors, although slightly repellent under some configurations, are not a practical method to repel starlings from nesting in structures.

To investigate whether the ion-enriched air exerted a bactericidal effect, an aerosol containing Salmonella Enteritidis (SE) was pumped into a sealed plastic chamber. Plates of XLT4 agar were attached to the walls, top, and bottom of the chamber and exposed to the aerosol for 3 h with and without the ionizer treatment. The plates were then removed from the chamber, incubated at 37 degree C for 24 h, and colonies were counted. An average of greater than 10 super(3) CFU/plate were observed on plates exposed to the aerosol without the ionizer treatment (control) compared with an average of less than 53 CFU/plate on the ionizer-treated plates. In another series of experiments, the SE aerosol was pumped for 3 h into an empty chamber containing only the ionizer and allowed to collect on the internal surfaces. The inside surfaces of the chamber were then rinsed with 100 ml phosphate-buffered saline that was then plated onto XLT4 plates. While the rinse from the control chamber contained colony counts greater than 400 CFU/ml of wash, no colonies were found in the rinse from the ionizer-treatment chamber. These results indicate that high levels of negative air ions can have a significant impact on the airborne microbial load, and that most of this effect is through direct killing of the organisms. This technology, which also causes significant reduction in airborne dust, has already been successfully applied for poultry hatching cabinets and caged layer rooms. Other potential applications include any enclosed space such as food processing areas, medical institutions, the workplace, and the home, where reduction of airborne and surface pathogens is desired.

As of 31 December 2000, T. piniperda was found in 303 counties in 12 US states (Illinois, Indiana, Maine, Maryland, Michigan, New Hampshire, New York, Ohio, Pennsylvania, Vermont, West Virginia, and Wisconsin) and in 43 counties in 2 Canadian provinces (Ontario and Quebec). A federal quarantine imposed in November 1992 regulates movement of pine (Pinus) trees, logs, and certain pine products from infested to uninfested areas within US. The forest products, Christmas tree, and nursery industries are affected by the quarantine. This paper summarizes information on the discovery and spread of T. piniperda in North America, survey efforts, recent interception history, development and changes in the federal quarantine, development of a national compliance management program, and extension and research efforts.

Quantitative fluorometric analysis showed the gene to be expressed most highly in seed, followed by moderate to low expression in non-seed tissues, such as hypocotyl and cotyledon, stem, leaf, and root. Histochemical localization revealed expression in rapidly dividing cells of transgenic seedlings, such as root tip and cotyledon. In mature vegetative plants, however, expression of Lox3:GUS was limited principally to epidermal layers, including epidermal hairs. Among the reproductive structures, Lox3:GUS expression was observed in pollen and in the stigmatic surface.

American pondweed (Potamogeton nodosus Poiret) winter buds, and hydrilla (Hydrilla verticillata (L.f.) Royle, monoecious and dioecious types) tubers were allowed to sprout in water in the dark. At two-to-three day intervals individual propagules and dependent shoots were analyzed for soluble sugars. There was a significant decline in propagule fresh weight over time indicating mobilization of stored materials. Sucrose was the most abundant soluble sugar in all the propagules, but found in higher concentrations in American pondweed winter buds than in hydrilla propagules. Fructose, glucose, raffinose, and sucrose were present in American pondweed, and hydrilla. Stachyose was present in all except dioecious hydrilla and sorbitol was not detected. During sprouting, soluble sugar concentrations decreased within the original propagule and increased in shoots for hydrilla biotypes. Fructose and glucose concentrations were greater in newly formed shoots than in winter buds of American pondweed by day 14 and in hydrilla shoots versus propagules by day 22. The striking increases in concentrations of these soluble sugars in propagules and newly emergent leaf tissue suggest that starch hydrolysis is a key metabolic control point during sprouting.

AN - 18368574; 5341914 AB - In a greenhouse trial, rice (Oryza sativa L.) cultivar Pusa Basmati-1 was grown in a Zn deficient Typic Ustochrept soil from IARI farm, New Delhi, India. The experimental design included two rates of inoculation with vesicular-arbuscular mycorrhizal fungi (VAMF), Glomus etunicatum (nil and inoculated) and different combinations of organic (farmyard manure, FYM) and inorganic (NPK, ZnSO sub(4)) fertilizers. The results revealed that a high intensity of root colonization in rice inoculated with G. etunicatum could be achieved by raising seedlings in P- and Zn-deficient soil in the nursery under aerobic conditions. Moreover, the VAMF that infected rice seedlings in the nursery also survived when the same seedlings were transplanted into pots under waterlogged conditions. The application of ZnSO sub(4) significantly increased the inflow of Zn to rice roots at the panicle-initiation stage (40 days after transplanting) relative to NPK. The former treatment also increased root length, root weight, root volume and total uptake of Zn and thereby increased the grain and dry matter yields. Alternatively, these variables were substantially enhanced by inoculating rice with the VAMF, G. etunicatum. The VAMF-colonized rice plants were more active in acquiring Zn from either added or native sources than non-colonized plants, and consequently the available-Zn content in soil was lower after the harvest of rice.

To address these various issues, numerous site-, watershed-, and landscape-scale studies are ongoing. In this region, lentic habitats provide breeding sites for Ambystoma, Rana, Bufo, Hyla, Taricha, and Dicamptodon species, with known elevational extents ranging from about 1900 to 3600 m, while terrestrial-breeding salamanders (Plethodon, Aneides, Ensatina, and Batrachoseps spp.) and other aquatic-breeders (Rhyacotriton, Ascaphus, other Rana spp.) have elevational extents ranging approximately 1000 to 2100 m. Inventory and monitoring programs are being established by government agencies due to threatened species issues and developing standards to maintain species persistence on public lands. Results of research, inventories, and multiple site monitoring (i.e., Bufo boreas) in the Oregon Cascade Range since 1981 demonstrate the variable population ecology associated with the extreme montane amphibian habitat heterogeneity, and numerous contributing factors to population losses and possible declines. A differential vulnerability among taxa, populations, and life history stages to a variety of site and time-specific stressors is apparent. These stressors include known and potential impacts of other species (e.g., ravens, fishes, fungi), drought, and anthropogenic disturbance. Management proposals are integrating differential species ecologies and disturbance susceptibilities by taking both site and landscape-scale approaches to buffer impacts to both breeding and nonbreeding habitats, and to address large-scale habitat connectivity.

After two decades of use, pronuclear microinjection protocols have changed little from the reliable, if not efficient, method described by Gordon and Ruddle. Experience has taught us that once microinjection skills are perfected there are only a few parameters one needs to be concerned about to successfully produce transgenic animals. Those parameters will be discussed, as will some new innovations that promise to finally increase efficiency of pronuclear microinjection methodology.

This program allows the USDA Forest Service and three other federal agencies to experiment with new or increased fees at up to 100 recreation sites per agency. The RFDP has sparked a public debate about the merits and demerits of charging fees for recreation on public lands. This study used the patented InfoTrend computer content analysis method to analyze the debate about RFDP fees on national forests expressed in a large electronic database of news media stories. The media have been found to both shape and reflect public opinion for a wide range of social issues. Analysis of large numbers of news stories using the InfoTrend method is a way to quickly and efficiently take the pulse of the public on a variety of social issues and indirectly measure public attitudes and beliefs. This method has the advantages over surveys, focus groups and interviews of being easily and rapidly updated, extending back in time several years to establish time trends and hence monitor changing attitudes and beliefs over time, and being expandable to include additional issues or dimensions. The main disadvantages of this method are that it may not be possible to analyze an issue with the same depth as with focus groups and interviews, and it provides an indirect measure of public opinion, which should be corroborated with direct measures. Over the period January 1, 1996 through September 30, 1999, favorable beliefs about RFDP fees expressed in our database of news media stories outnumbered unfavorable expressions by a factor of about 2 to 1, comparable to the findings of surveys and interviews. The share of favorable attitudes toward RFDP fees decreased over time due to an increase of expressions of unfavorable attitudes for the four southern California forests and the national forests of Oregon and Washington. In the rest of the country, however, there was no change in the share of favorable attitudes over time. The nature of the public debate about RFDP fees was found to differ substantially between those who hold a favorable view of fees and those who oppose them. Arguments and beliefs in support of the fees have been overwhelmingly utilitarian and pragmatic. In contrast, arguments and beliefs held by those opposing fees have tended to be focused on issues of rights, fairness, and wilderness values. Much of the support for RFDP fees was found to be conditional: Many people are willing to pay the fees so long as the revenue collected is used locally to fund needed improvements in recreation areas and facilities.

We established plots within three canopy types (open, old-growth, and dense young pine) with different grass species compositions in a Pinus ponderosa forest in northern Arizona and collected vegetation data and surface (0-2 cm) and subsurface (2-7 cm) mineral soil samples. Surface soil phytolith assemblages strongly reflected vegetation at the site scale (within several km super(2)). Local vegetation patterns (< 50 m super(2)) associated with overstory canopy types were weakly detected. Significantly fewer C sub(4) grass and ponderosa pine phytoliths were found in subsurface compared to surface soils. Surface delta super(13)C values showed no difference among canopy types. Subsurface delta super(13)C values were significantly (+0.83ppt) more enriched in super(13)C than surface values. Phytolith assemblages and delta super(13)C of SOM reflect long-term accumulation of organic matter in soils and may not mirror contemporary vegetation for many reasons, including spatial shifts in species distribution and productivity. Considering all our phytolith and delta super(13)C evidence, we suggest that C sub(4) grasses were more widely distributed but less abundant, grasses were more spatially continuous, total grass productivity was greater, and species in the genus Koeleria and Bromus were more common in the past.

When L. monocytogenes was inoculated into cooked beef bologna emulsion containing 0, 1.75, or 3.5% SPC the gamma radiation D sub(10) values, at radiation doses of 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 kGy, were 0.66, 0.68, and 0.71 kGy, respectively. Soluble antioxidant power, as determined by the Ferric Reducing Antioxidant Power (FRAP) assay was 1958, 3572, and 5494 mol in bologna emulsion containing 0, 1.75 and 3.5% SPC, respectively. Soluble antioxidant power was not affected by ionizing radiation. SPC did not prevent ionizing radiation induced lipid oxidation as determined by Thiobarbituric Acid Reactive Substance (TBARS) assay. Hunter color analysis of both unirradiated and irradiated bologna slices containing SPC indicated decreased a-value as a result of irradiation, while the addition of SPC helped maintain b-value and L-value. The inclusion of SPC did not represent a barrier to ionizing radiation pasteurization of fine emulsion sausages for the parameters examined.

Intergeneric F sub(1) hybrids (2n = 4x = 28; ABJ sub(1)J sub(2)) between durum wheat (Triticum turgidum; 2n = 4x = 28; AABB) cultivars Lloyd or Langdon and Th. junceiforme were synthesized. Most of the pairing in F sub(1) hybrids was between the J sub(1)- and J sub(2)-genome chromosomes. Some pairing occurred between wheat chromosomes and alien chromosomes, resulting in segmental exchange that was confirmed by fluorescent in situ hybridization (FISH). The F sub(1) hybrids were largely male-sterile and were backcrossed, as the female parent, to the respective durum cultivar. Backcrosses from Lloyd x Th. junceiforme hybrids yielded fertile partial amphiploids (2n = 6x = 42; AABBJ sub(1)J sub(2)) as a result of functioning of unreduced female gametes of the hybrid. Lloyd proved to be a more useful durum parent than Langdon in crosses with Th. junceiforme designed to transfer scab resistance genes. Pairing in the amphiploids was characterized by preferential pairing, which resulted in bivalent formation. However, some intergeneric pairing also occurred. Several fertile hybrid derivatives were produced by further backcrossing and selfing. The introduction of alien chromatin into the durum complement was confirmed by FISH. Hybrid derivative lines had significantly lower mean infection scores (p = 0.01), the best showing 10.93% infection, whereas the parental durum cultivars had 70.34% to 89.46% infection. Hybridization with wild relatives may offer an excellent means of introducing scab resistance into durum wheat.

There are numerous studies in the literature discussing gossypol and aflatoxin toxicities in livestock and processing methods for reducing gossypol levels in cottonseed. However, there is very limited information in the literature within the last 30 years on how aflatoxin is affected by processing. Evaluation studies were conducted to determine if an extrusion process affected gossypol and aflatoxin levels in cottonseed without negatively impacting the nutritional value of the product, and if these reductions were consistent with the literature. Results from the gossypol study showed a 71 to 78% decrease in free gossypol levels due to the extrusion process, which were lower than some reported methods of processing and consistent with others. Results from the aflatoxin studies showed reductions of 50% when the material was processed by two stages of extrusion at a temperature of 132 degree C. Similar reductions have been reported on roasting corn at temperatures of 140 to 143 degree C. The extrusion temperatures used in the evaluation studies did not significantly alter most of the nutritional values analyzed in the study. However, soluble protein was decreased at the higher temperatures. There were no significant differences in analyzed nutritional values based on multiple stages of processing. Results from the evaluation study indicate that extruding cottonseed to reduce gossypol and aflatoxin levels is an area of research that should be further explored, primarily due to the advances made in the aflatoxin and gossypol testing methods during the last 30 years.

Surface treatment with 70% EtOH, followed by immersion in 10 super(8) CFU/mL E. coli inoculum deposited an average of 4.4 log sub(10)CFU/cm super(2) cell population on the cantaloupe surface. The efficacy of washing inoculated cantaloupe was dependent on storage interval between inoculation and treatment. Dipping the cantaloupes in solutions containing 1000 mg/L chlorine or 5% peroxide for 5 min, within 24 h of inoculation, caused a 2 log sub(10) CFU/cm super(2) reduction of the indigenous surface microflora and a 3-4.0 log sub(10) CFU/cm super(2) reduction in E. coli. The efficacy was less when the interval between inoculation and treatment exceeded 24 h. Chlorine appeared to be a better antimicrobial agent than hydrogen peroxide against E. coli ATCC 25922 inoculated on cantaloupe surfaces while hydrogen peroxide was better in reducing surface microflora of cantaloupe.

During the past ten years, over 80 biocontrol products have been marketed worldwide. A large percentage of these have been developed for greenhouse crops. Products to control soilborne pathogens such as Sclerotinia, Pythium, Rhizoctonia and Fusarium include Coniothyrium minitans, species of Gliocladium, Trichoderma, Streptomyces, and Bacillus, and nonpathogenic Fusarium. Products containing Trichoderma, Ampelomyces quisqualis, Bacillus, and Ulocladium are being developed to control the primary foliar diseases, Botrytis and powdery mildew. The development of Pseudomonas for the control of Pythium diseases in hydroponics and Pseudozyma flocculosa for the control of powdery mildew by two Canadian research programs is presented. In the future, biological control of diseases in greenhouses could predominate over chemical pesticides, in the same way that biological control of greenhouse insects predominates in the United Kingdom. The limitations in formulation, registration, and commercialization are discussed, along with suggested future research priorities.

Much research has been conducted on the erosion and loss of P in sediments and surface runoff. Recently, P loss in sub-surface runoff via agricultural drainage has been identified as environmentally significant. High soil P levels are considered as a potential source of P loss. However, without favourable hydrological conditions P will not move. In this paper, we review the basis of soil P release into solution and transport in surface and sub-surface runoff. Our objectives are to outline the role of soil P and hydrology in P movement and management practices that can minimize P loss to surface waters. Remedial strategies to reduce the risk of P loss in the short-term are discussed, although it is acknowledged that long-term solutions must focus on achieving a balance between P inputs in fertilizers and feed and P outputs in production systems.

In the current study, we demonstrate the effect of RPCF on vancomycin-resistant enterococci (VRE) in the presence and absence of subtherapeutic levels of vancomycin. Also examined was the ability of VRE to transfer vancomycin resistance to endogenous Enterococcus faecalis 137.1. When RPCF was challenged with VRE, the rate of VRE clearance was dependent on the method of challenge. In the control experiment, RPCF was challenged with 7.0 log sub(10)/CFU/ml VRE. Clearance of VRE from the culture was observed within 7 days at a rate of 1.44 log sub(10)/day. RPCF containing 0.001 mu g/ml vancomycin cleared VRE at a slightly lower rate of 0.94 log sub(10)/day. RPCF containing 0.01 mu g/ml or 0.1 mu g/ml vancomycin reduced the level of VRE from 7.0 log sub(10)/CFU/ml to 2.0 log sub(10)/CFU/ml within 9 days, but failed to clear the VRE after 24 days. During the period of decline, the VRE clearance rate for the 0.01 mu g/ml and 0.1 mu g/ml vancomycin-treated cultures was 0.52 log sub(10)/day, and 0.53 log sub(10)/day, respectively. E. faecalis 137.1 endogenous to RPCF did not acquire the vancomycin resistance genes throughout the experiment as evidenced by direct selection, ribotyping, and pulsed-field gel electrophoresis.

The construction of a paved road running through the middle of the peninsula modified the transversal flow of water. Five sites were sampled along this road: I. Coastal site near the village of Ajuruteua, II. Tidal creeks flowing into the lower Caete river, III. Central lagoons, IV. Avicennia basin forest, and V. Upper Caete estuary near the village of Acarajo. All but site III, harbored the three common mangroves species Rhizophora mangle, Laguncularia racemosa and Avicennia germinans. Monospecific communities of shrub-like Avicennia germinans stands characterized site III. Soils were highly organic therefore bulk density was inversely correlated to the concentrations of C and N. Sites I and V had the lowest salinity values. The highest salinity was measured in the Avicennia dominated sites III and IV. Nitrogen showed similar values in all sites, but S was clearly more abundant in sites II and V. Leaf dimensions varied significantly between sites. Considering leaf area expansion as indicator of stress and delta super(13)C values as indicator of water use efficiency, site V was more favorable for Rhizophora and Laguncularia while site IV was so for Avicennia. Leaf shape measured as the length/width ratio was more variable in Avicennia and least variable in Rhizophora. Leaf nutrients were not correlated with soil nutrient content. Sodium and Mg were more concentrated in Avicennia leaves while Fe was more concentrated in Laguncularia and Mn in Rhizophora leaves. Avicennia showed the highest N and the lowest Ca concentrations as expected for being a glycinbetaine accumulator and an oxalate-former. delta super(13)N values indicate that N source for mangroves is essentially the mineralization of organic matter.

Snag surveys were used to describe habitat, and both breeding bird surveys and nest surveys were used to characterize the bird community. Stands with the medium snag density treatment had the highest abundance, species richness, and nesting population of cavity nesters. The reasons for this may be: 1) snags were not evenly distributed within a stand such that both clumped and dispersed snag density habitats were interspersed in this treatment, and 2) a greater proportion of ponderosa pine snags in medium density treatments may have attracted species that prefer ponderosa pine for nesting and foraging. Ponderosa pine was preferred for nest sites and large snags (>48 cm dbh) provided nesting habitat for more species than smaller snags. However, smaller snags were used for nesting and foraging by some species.

Our goal was to determine the current status of western gray squirrels in this region. In 1998, we found five western gray squirrels in 538 hours of foot surveys in 133 oak sites. In 1999, we expanded our survey effort and included surveys on foot, surveys with simulated squirrel calls, live trapping, and bait stations with motion-sensitive cameras. No western gray squirrels were detected in any oak sites in 1999. One western gray squirrel was photographed in a ponderosa pine stand adjacent to oaks. The western gray squirrel population on Fort Lewis appears to have declined severely since low population numbers were reported in 1992-1993. Our ability to formulate mutually exclusive hypotheses underlying the decline of the western gray squirrel on Fort Lewis is limited by our lack of understanding of how these squirrels persist in highly-fragmented oak ecotones. Without intervention, however, the continued existence of this species in the Puget Trough may be doubtful.

Study areas were in the Puget Trough physiographic province and western hemlock vegetation zone. Most oak communities were ecotonal between prairie and Douglas-fir forest. Small mammals were sampled at each site using paired lines of live traps for four nights, July and August 1999. In order of decreasing abundance, the deer mouse, vagrant shrew, Trowbridge's shrew, and creeping vole were the most abundant and widespread species. The dusky shrew and the southern red-backed vole were infrequently captured in oak ecotones but were abundant in nearby second-growth Douglas-fir forest. The relative influences of prairie versus Douglas-fir forest on oak ecotones determined understory plant composition and occurrences of small mammal species. The combination of abundant vagrant shrews and few dusky shrews in oak ecotones suggest that soil food webs and organic matter accumulation differed between oak ecotones and Douglas-fir forest.

Mycosis in B. argentifolii nymphs varied according to the host plant on which the nymphs were reared but not according to the population. Both populations of whiteflies reared on cotton were consistently significantly less susceptible to infection by either fungus than when reared on melon. We hypothesized that the cotton plant produced a fungal inhibitor that may confer protection on whiteflies feeding (and possibly sequestering) upon it. Germination of conidia of both fungi was strongly inhibited (below 12% germination) on the cuticle of nymphs reared on cotton but was over 95% on the cuticle of nymphs reared on melon. We further hypothesized that the terpenoid gossypol, produced by many cultivars of cotton, might have been involved in antibiosis. Gossypol mixed with Noble agar at five concentrations was tested for its effects on germination of conidia of both fungi P. fumosoroseus was highly tolerant of gossypol, even at the relatively high concentration of 1000 ppm, while B. bassiana tolerated gossypol at concentrations up to 500 ppm and strong inhibition only occurred in presence of gossypol at 1000 ppm. Our in vivo findings on cotton and on the insect's cuticle pointed at a potential host plant-mediated antibiosis. The in vitro tolerance of P. fumosoroseus and partial tolerance of B. bassiana to gossypol disagreed with our in vivo data. Gossypol concentrations higher than 1000 ppm might have increased the sensitivity of the fungi in our in vitro tests. Sequestered gossypol (and/or other cotton plant allelochemicals) by B. argentifolii nymphs would explain, at least partially, the insect's defense against the pathogens.

To evaluate the effects of elevated atmospheric CO sub(2) on litter chemistry and decomposition, we performed a 111 day laboratory incubation with leaf litter of trembling aspen (Populus tremuloides Michaux) produced at 36 Pa and 56 Pa CO sub(2) and two levels of soil nitrogen (N) availability. Decomposition was quantified as microbially respired CO sub(2) and dissolved organic carbon (DOC) in soil solution, and concentrations of nonstructural carbohydrates, N, carbon (C), and condensed tannins were monitored throughout the incubation. Growth under elevated atmospheric CO sub(2) did not significantly affect initial litter concentrations of TNC, N, or condensed tannins. Rates of decomposition, measured as both microbially respired CO sub(2) and DOC did not differ between litter produced under ambient and elevated CO sub(2). Total C lost from the samples was 38 mg g super(-1) litter as respired CO sub(2) and 138 mg g super(-1) litter as DOC, suggesting short-term pulses of dissolved C in soil solution are important components of the terrestrial C cycle. We conclude that litter chemistry and decomposition in trembling aspen are minimally affected by growth under higher concentrations of CO sub(2).

Alternatives to land-farming or solid waste disposal include biostimulation and phytoremediation. This research investigated the ability of compost, corn stalks, corn fermentation byproduct, peat, manure, and sawdust at rates of 0.5% and 5% (w/w) to stimulate biodegradation of atrazine [6-chloro-N-ethyl-N'-(1-methyethyl)-1, 3,5-triazine-2,4-diamine], metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N- (2-methoxy-1-methylethyl)acetamide], and trifluralin [2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl)benzenamine] added as a mixture to soil. Initial concentrations were 175 plus or minus 42 mg atrazine kg super(-1) soil, 182 plus or minus 25 mg metolachlor kg super(-1) soil, and 165 plus or minus 23 mg trifluralin kg super(-1) soil. After amendment addition, 30% of the atrazine, 33% of the metolachlor, and 44% of the trifluralin was degraded over 245 days, which included 63 days' aging prior to amendment additions. Atrazine degradation was enhanced by 0.5% manure, 5% peat, and 5% cornstalk amendments compared to nonamended soils. Metolachlor degradation was enhanced by all amendments at the 5% level, except for compost and peat. Amendments had no effect on trifluralin degradation. The 5% addition of compost, manure, and cornstalks resulted in significant increases in bacterial populations and dehydrogenase activity. A second experiment compared the persistence of atrazine, metolachlor, and trifluralin applied in a mixture to their persistence in soil individually. A combined average of 123 mg atrazine kg super(-1) remained in soil treated with the three-herbicide mixture compared to 31 mg atrazine kg super(-1) remaining in soil treated with atrazine only. Atrazine mineralization and atrazine-degrading microorganisms were suppressed by high concentrations of metolachlor, but not by trifluralin.

Soil moisture was adjusted to -33 kPa and super(14)C- and analytical-grade imidacloprid-urea and imidacloprid-guanidine were added to the soil at a rate of 1.0 mg kg super(-1). Spiked soils were incubated at 25 degree C for 8 weeks. Replicate soil samples were periodically extracted successively with 0.01 N CaCl sub(2), acetonitrile, and 1 N HCl. Imidacloprid-urea sorption, as indicated by sorption coefficient values, was highest in the soil with highest organic C content, and increased by an average factor of 2.6 in three soils during the 8-week incubation period. Imidacloprid-guanidine sorption increased by a factor of 2.3 in the same soils. The increase in sorption was the result of a decrease in the metabolite extractable with CaCl sub(2) (solution phase); the amount of metabolite extractable with acetonitrile and HCl (sorbed phase) did not significantly change with incubation time. It appears the increase in sorption was because the rate of degradation in solution and on labile sites was faster than the rate of desorption from the soil particles. It may have also been due to metabolite diffusion to less accessible or stronger binding sites with time. Regardless of the mechanism, these results are further evidence that increases in sorption during pesticide aging should be taken into account during characterization of the sorption process for mathematical models of pesticide degradation and transport.

Infectious diseases that induce the acute-phase response also impair the assessment of vitamin A status by transiently depressing serum retinol concentrations. Vitamin A deficiency impairs innate immunity by impeding normal regeneration of mucosal barriers damaged by infection, and by diminishing the function of neutrophils, macrophages, and natural killer cells. Vitamin A is also required for adaptive immunity and plays a role in the development of T both-helper (Th) cells and B-cells. In particular, vitamin A deficiency diminishes antibody-mediated responses directed by Th2 cells, although some aspects of Th1-mediated immunity are also diminished. These changes in mucosal epithelial regeneration and immune function presumably account for the increased mortality seen in vitamin A-deficient infants, young children, and pregnant women in many areas of the world today.

We sought to document the distribution of martens in this region using historical records and to understand recent change in their distribution. We described the distribution of martens from 1900 to 1949 using museum and trapping records and compared it to recent (1989-1998) detections at camera and track-plate stations. Martens were detected at only 12 of the 237 (5.1%) survey sample units in coastal California, Oregon, and Washington. Martens are absent from most of the historical range of the Humboldt marten (M. a. humboldtensis) in California and also may have declined on the Olympic Peninsula of Washington. Few data exist from northwestern Oregon and southwestern Washington, but the limited amount of protected public land and absence of reported road kills are reasons for concern for populations in this region. Martens still occur in the central and southern coastal mountains of Oregon. Our results suggest that conservation of martens in coastal forests will require new initiatives to protect existing populations and new efforts to document all populations of martens in this region. Conservation measures should include a reevaluation of timber harvest plans that affect habitat in coastal forests, interagency cooperation on a coastal marten conservation assessment, and the collection of new survey information, especially on private lands in southwestern Washington and northwestern Oregon.

Modeling is used to examine alternative fuel treatment options, project potential ecosystem changes, and assess risk to life and property. Models are also used to develop fire prescriptions, conduct prescribed fire operations, and predict fire behavior. Fire models and information systems have greatly influenced fuel assessment methods. As an example, we examine the evolution of technology used to put Rothermel's fire spread model into application. A review of fire and fuel modeling terminology is given, and the relationship between fire models and fuel models is explained. We review current fire modeling work and the influence that it will have on fuel characterization. Finally, we discuss opportunities and challenges involved in the use of advanced computers, the Internet, Geographic Information Systems (GIS), and remote sensing in fire and fuel management.

Fire effects modeling may be conducted at a range of temporal and spatial scales. First-order fire effects are those that are the direct result of the combustion process such as plant injury and death, fuel consumption and smoke production. Modeling these effects provides an important cornerstone for models that operate at larger spatial and temporal scales. Detailed physical models of heat transfer and the combustion process under development should provide a vehicle for quantifying fire treatment and predicting fire effects. Second-order fire effects are indirect consequences of fire and other post-fire interactions such as weather. They may take place a few hours to many decades after a fire. Some important second-order fire effects are smoke dispersion, erosion, and vegetation succession. Many approaches have been used to model fire effects including empirical, mechanistic, stochastic, and combinations of all three. Selection of the appropriate model approach and scale depends on the objectives of the modeler, as well as the quality and quantity of available data. This paper is not meant to provide an exhaustive review of fire effects models. Instead, it presents a background in approaches to modeling fire effects to provide managers a basis for selecting and interpreting simulation tools.

These three air quality issues relate directly to forest and agriculture burning. Fire generates PM sub(2.5) and ozone precursor gases that reduce visibility. Hence, wild and agricultural land managers will be subject to these air quality regulations much as industrial and mobile sources have been for the past 25 years. In addition, these new regulations come at a time when private as well as public land managers throughout the United States are developing plans to increase their application of fire as a management tool. Prescribed fire will remain viable as a tool for land managers with these new regulations but only under a responsible smoke management paradigm. This paradigm will include formal 'state-approved' Smoke Management Programs and will require the use of new and 'approved' technologies that have been subjected to public and stakeholder scrutiny as regulatory tools. These programs will acknowledge that wildland fire is different from conventional human-caused air pollution sources. They will recognize that the managed use of fire is a superior option to wildfire from public safety and health perspectives. But they will also require greater utilization of non-burning alternatives in all circumstances, especially where fire is used for economic rather than ecological reasons. Through better smoke management and greater use of non-burning alternatives, steadily reduced smoke emissions will likely result.

The spatial variability of precipitation within a region is defined by differences between station and regional standardised values. The spatial variability is quantified at the monthly, seasonal and yearly time scales for the central Oklahoma "super climate division" and the four "climate divisions" included in. For the super climate division, the standard deviation of the differences between station and regional standardised values ranges from minimum values during the winter around 0,55 to maximum values during the summer around 0,80. The decrease of the spatial variability associated with the increase of the time scale is of about 35% from month to season, of about 45% from season to year. Whereas the decrease of spatial variability associated with the decrease in space scale is of about 35% from super-climate division to climate division. An analysis of the distribution of the differences allows to define confidence envelope for local precipitation around the regional value. This study clearly demonstrates the critical influence of the spatial variability of precipitation and the additional uncertainty it introduces in the downscaling of regional information to local applications.

AN - 18209295; 5276844 AB - The endangered red-cockaded woodpecker (Picoides borealis) is well adapted to fire-maintained pine ecosystems of the southeastern United States. Management practices vary greatly among land ownerships. In some wilderness areas and state parks, a "no management" policy has eliminated use of prescribed fire, artificial cavities, and woodpecker translocation, tools that have proved effective elsewhere in recovering woodpecker populations. We compared forests with essentially "no management" to actively managed forests of similar tree ages and similar red-cockaded woodpecker population demographics. We also compared sites that had received no management in the past to the same sites after management. In every case, populations in forests that did not use state-of-the-art management for woodpeckers declined severely compared to those in managed forests. Because managed forests typically used all available management techniques concurrently, it was not possible to separate and rank effectiveness of specific management activities. One exception was the Wade Tract in Georgia, where prescribed fire was the primary activity for herbaceous layer and hardwood management in a high-density, stable woodpecker population. Wilderness areas, which are intended to be pristine places that preserve biodiversity, are losing red-cockaded woodpeckers, a keystone species in the ecosystem, at an alarming rate. Collectively, 9 groups of red-cockaded woodpeckers were present in 4 wilderness areas in Texas national forests in 1983. At the close of the millennium, only one woodpecker group remained and its continued existence is unlikely without management. The very fragmented features of present-day landscapes and intervention by humans impair the effectiveness of natural disturbance processes, primarily growing-season fire, that historically produced and maintained open pine savannas with grass-forb herbaceous layers in the pre-Columbian forests of the southeastern U.S.; therefore, active management must be used if the red-cockaded woodpecker is to persist.

Fungal growth and aflatoxin B sub(1) production were also determined in potato-dextrose-agar petri plate cultures inoculated with aflatoxigenic Aspergillus spp. containing an atmosphere of volatiles emitted from 0.25 ml, 0.5 ml, and 1.0 ml CNO added to the plates. After 5 days' incubation, fungal radial growth was reduced by 7-29% and aflatoxin B sub(1) production by 0-67%. GC/MS analysis of the head space volatiles of the CNO indicated that the reduction of fungal growth and aflatoxin B sub(1) was probably due to low molecular weight hydrocarbons, aldehydes, alcohols, and sulfur compounds emitted at 30 degree C in the dry culture. These results suggest that volatiles emitted from CNO at 30 degree C in plate cultures were more fungistatic and consequently inhibited aflatoxin production more than neem oil added in liquid cultures.

Ponds were situated within a hardwood-invaded or a savanna-like long- leaf pine-wiregrass upland matrix. Movement (N = 1444) was monitored using intermittent drift fences with pitfall and funnel traps at eight isolated, ephemeral ponds February 1994 to January 1999. Adult pond use was low but relatively constant among years and did not differ between habitat matrices. Juvenile recruitment was significantly higher in the savanna-like upland matrix. The number of adults using ponds was positively correlated with the number of next-year's recruits in only one year. Recruitment rates were relatively low (maximum 175 captured/pond/yr), but juveniles were produced from most ponds in three of five years. Recruitment was negligible in 1994 because of ponds drying and in 1997 for unknown reasons. Juvenile body size differed significantly among years and ponds. Body size was negatively correlated with the number of juveniles exiting ponds in only one year, suggesting that intraspecific competition is only one of many factors affecting juvenile body size. Most emigration by metamorphic juveniles occurred May through August and was unrelated to rainfall. Dates of first emergence and length of emigration periods varied. A high proportion of juveniles with tailbuds and similar tailbud lengths in most months suggest that metamorphosis occurred throughout the emigration period. High variability in juvenile recruitment success and significant differences in body size among years and ponds suggests that each is influenced by factors at both a landscape (e.g., rainfall and pond hydrology) and within-pond scale (e.g., competition and predation).

Much of this mosaic has been destroyed. The largest remaining portion is on Fort Lewis Military Reservation. We examined oak communities on Fort Lewis to assess encroachment by exotic plants and by Douglas-fir, to determine amounts of regeneration of oak and other tree species, and to compare oak community diversity with that of nearby Douglas-fir forests and glacial till prairies. For the 22 largest communities, we determined densities of trees, distributions of tree diameters and heights, amounts of regeneration for each tree species, evidence of exogenous disturbances, and covers of vascular understory species. For study sites, we calculated basal areas of tree species, richness and diversity of vascular plants, and percentages of species that were exotic. We constructed species accumulation curves for oak communities, Douglas-fir forests, and prairies. We performed Bray-Curtis and weighted averaging ordinations for 176 sampling plots from the 22 sites. Oak communities were typically more diverse than either Douglas-fir forests or prairies and were transitional in species composition between them. However, oak communities contained numerous exotics, particularly Scot's broom (Cytisus scoparius) and colonial bentgrass (Agrostis capillaris). Most oak communities contained large-diameter Douglas-firs and other tree species and appeared to be transforming to conifer or conifer/mixed hardwood forests. With succession, exotic species become less prevalent, but the extent and abundance of oaks is diminished. Maintenance of oak communities, and the PSA natural mosaic, may require tree-density management in oak stands, removal of Douglas-fir, development of replacement oak sites, prescribed burning, and mechanical suppression of exotics before burning.

Mean estimated relative volume of food items in 621 scats was 35% grasses, 24% insects, 16% fruit, 11% soil and wood, 10% animal remains, and 4% leaves and stems. During June, remains of mule deer (Odocoileus hemionus) and elk (Cervus elaphus) occurred in 44% of the scats in 1998 and in 25% in 1999, at a time when other protein-rich food sources were unavailable. Between May and October, > 40% of all scats collected in each month contained insects, and 98% of those scats collected in July contained insects. A significantly higher volume of insects occurred in scats in 1999 compared to 1998, probably because berries were scarce in 1999. Of the 434 scats containing insects, 40% contained carpenter ants (Camponotus spp.), 45% other small ants (Lasius sp, Tapinoma sp., Aphaenogaster sp.), 36% forest ants (Formica spp.), and 23% yellowjackets (Vespula spp., Dolichovespula sp.). Because these ant species are all log-dwelling, management for coarse woody debris is an important consideration in maintaining this important food resource for black bears in northeastern Oregon.

Intended (target) effects and unintended (non-target) effects of GEMs must currently be evaluated prior to field testing or commercial use. We present soil and rhizosphere microbial community effects testing of two GEMs, Pseudomonas chlororaphis 3732RN-L11 and Pseudomonas fluorescens 2-79RN-L3, parental strains of these organisms and an uninoculated treatment using five diverse soils planted to wheat. An assay using BIOLOG registered GN plates measured microbial community functional responses on wheat roots with adhering soil. Overall differences using multivariate statistical methods were highest at inoculation, and these effects persisted while the inoculated organisms were detectible on selective media. Differentiation based on lacZY genes engineered to the chromosome of both GEMs was significant for the 3732 GEM in all five soils tested, but not for the 2-79 GEM in a single soil. Lactose utilization in uninoculated microbial communities varied around a low baseline value. Direct fatty acid extraction and analysis of soil from around wheat roots was also performed using a novel method. Fatty acid analysis differentiated the 3732 GEM from all other treatments, but did not distinguish the 3732 parent inoculated from uninoculated treatments. As with the BIOLOG assay, multivariate statistical differences from fatty acid analysis decreased between GEM inoculated and uninoculated populations as viable counts of the GEM declined. Neither assay showed measurable community-level effects when inoculated organisms declined below detection, though three of six soils with surviving GEM populations still had significant effects after 105 days.

We compared the percentage of land area in IRAs and conservation reserves across three geographic divisions (Alaska, East, and West), 83 ecoregions, 10 elevation zones, and 11 land-cover classes. We also summarized variation in the size class distribution of IRAs. Of the 83 ecoregions evaluated in the United States, 28 have >12% of their total area in conservation reserves. If IRAs are considered with conservation reserves, the number of ecoregions exceeding the 12% threshold increases from 28 to 32. When only national forest land in the ecoregions is considered, the area of designated wilderness exceeds 12% in 18 of the 45 ecoregions summarized. If IRAs are considered along with designated wilderness, the number of ecoregions exceeding the 12% threshold increases from 18 to 32. On national forest land below 1500 m, 10% is designated wilderness and 18.5% is IRA. Above 1500 m, 20% is designated wilderness and 31.5% is IRA. If IRAs are considered along with designated wilderness, all land-cover classes (except water in the West) would exceed the 12% threshold in Alaska and the West. In the East, only the evergreen forest class would exceed the 12% threshold when IRAs are considered with designated wilderness. Of 462 polygons of designated wilderness in the national forests, 353 are 101 175 ha increases to 45. These results highlight the contribution that IRAs could make toward building a representative network of conservation reserves in the United States. Including these areas as reserves would expand ecoregional representation, increase the area of reserves at lower elevations, and increase the number of areas large enough to provide refugia for species needing large tracts relatively undisturbed by people. Even with the addition of IRAs, many ecoregions in the United States would remain underrepresented in the reserve network, especially in the East.

Dendroctonus frontalis attacks and kills southern pines, introducing fungi into the tree. Ophiostoma minus, may initially aid beetles in killing trees, but later this "bluestain" fungus becomes an antagonist, competing with larvae for host phloem. Two additional fungi, Entomocorticium sp. A and Ceratocystiopsis ranaculosus are carried within a specialized mycangium and inoculated into phloem where they are fed upon by beetle larvae. The beetle also vectors several species of phoretic mites which transport spores of O. minus and C. ranaculosus and can complete their life cycle upon these two fungi. A similar interaction occurs between Ips avulsus and its fungal (Entomocorticium spp.) and mite (Elattoma bennetti) symbionts. Larval beetles feed on fungus as do the mites. Female mites feed on fungus growing within beetle galleries, swelling to many times their normal size. Larval mites develop and mate within the females who burst open, giving birth to reproductively mature females. These relationships may be best understood by considering the manner in which symbioses vary with time and resources, and the degree to which other species may affect interactions among symbionts.

We used Forest Inventory and Analysis surveys to analyze trends from 1946 to 1998. Dramatic regional differences occurred in distribution of early successional forests. The northeastern region had the least proportion of young forest (16%), followed by the north-central (24%) and southern (29%) regions. The least amount of young forest occurred in the Central Plains (15%) and New England (16%), whereas the greatest occurred in the pine-dominated Coastal South (32%). Differences also existed among individual states, ranging from 3% (Illinois) to 38% (Alabama). Long-term declines also were evident within the north-eastern and north-central regions. Selective harvesting, fire suppression, urban sprawl, and cessation of agricultural abandonment contributed to the present imbalance in distribution of young forests. Private ownership predominates in the East and presents a significant challenge to provide young forests. Absence of proactive management on private lands may promote continued declines in early successional forest within many eastern areas.

We review types of semi-wooded, early successional habitats in the eastern U.S. and information on their status, and discuss management and planning approaches for their conservation. These habitats are dominated by persistent shrubs, seedling-sapling-sized trees, grasses, and forbs. The area of seedling-sapling forests and many natural shrubland habitats have declined in most of the eastern U.S. Silviculture creates early successional habitats primarily by regenerating stands. The selection of a regeneration method, size and distribution of cuts, and rotation age or reentry period influence availability of these habitats. Multi-scale planning approaches can be used to address regional concerns for these habitats and biological diversity, while facilitating landscape and local planning. We suggest that management for early successional communities is an important issue that should be addressed in conservation and land-management planning. Professional land managers and planners and the public need to address how many of these wildlife species we want and how we want them distributed throughout the region. In many landscapes silviculture will play an important role in providing habitat for these species.

I review 3 key ways that people perceive, use, and value forest landscapes, emphasizing selected types of early successional landscapes in the eastern United States (U.S.): production and consumption of timber and nontimber forest products, visual and aesthetic perceptions, and recreational uses and choices. Site- and regional-scale forest planning and design efforts can be improved by better understanding the human dimensions of early successional landscapes, such as siting facilities for recreation and planting native vegetation for aesthetics. Various types of communication, such as signs, brochures, and opportunities for on-the-ground experience, can help interpret the significance of these landscapes to the public for wildlife and human values. I suggest some research directions to increase knowledge about the human dimensions of early successional landscapes.

We evaluated the effectiveness with which the biomark associated with iophenoxic acid (IA) injections was transferred from domestic goats to coyotes (Canis latrans) that fed on them. We injected doses of 100, 300, or 1,000 mg of IA into goats to raise serum iodine levels, fed meat from the injected goats to coyotes, and monitored serum iodine levels in both species for about 120 days. Within 3 days, mean serum iodine levels in goats increased from 5.33 mcg/100 ml to over 2,847, 10,233, and 11,567 mcg/100 ml, respectively, for the 100-, 300-, and 1,000-mg IA treatments. A gradual dissipation of serum iodine concentrations in the goats ensued, approaching mean levels of 943, 3,213, and 6,310 mcg/100 ml of serum by day 120. When we fed coyotes (2/treatment) 500 g of meat from IA-treated goats, mean serum iodine levels among the coyotes increased within 2 days from 8 mcg/100 ml to 194, 410, and 645 mcg/100 ml of serum respectively for the 3 treatments. Mean serum iodine concentrations among these coyotes then declined systematically to 30, 45, and 82 mcg/100 ml of serum 112 days after ingestion. When we fed coyotes 500 g of meat from goats slaughtered 120 days after they had been injected with IA, mean serum iodine levels increased from base levels (8 mcg/100 ml of serum) to 69, 242, and 526 mcg/100 ml respectively for the 100-, 300-, and 1,000-mg treatments. We concluded that we were able to detect coyotes that fed on marked goats any time during a 120-day period after the goats were treated. Nonlinear regression analysis suggested a relation between levels of serum iodine achieved and IA dose rate (mg/kg) received by the goats, with iodine levels reaching saturation with intramuscular injections of 25-30 mg/kg IA.

Such models can provide useful predictions at large scales, but it has been difficult to evaluate their performance. Using the network of plots comprising the comprehensive and spatially extensive Forest Inventory and Analysis (FIA) data set collected and maintained by the USDA Forest Service, we applied methods typically used in field measurements to develop estimates of forest biomass and NPP for the mid-Atlantic region of the United States at a scale appropriate for comparison with model predictions. Plot-level and tree-level forest inventory data from a subset of plots were used together with species-specific biomass regression equations to calculate maximum current biomass and NPP values for the mid-Atlantic region. Estimates at the plot level were aggregated by forest type and to the 0.5 degree x 0.5 degree scale for analysis and comparison with process model predictions. Maximum current forest biomass averaged 248 and 200 Mg times ha super(-1) times yr super(-1) in hardwood and softwood forest types, respectively; wood biomass increment averaged 559 and 460 g times m super(-2) times yr super(-1) in hardwood and softwood forest types, respectively. Aggregated to the 0.5 degree x 0.5 degree scale, forest biomass ranged from 101 to 326 Mg/ha, while wood biomass increment ranged from 254 to 1050 g times m super(-2) times yr super(-1). Biomass and NPP estimates for closed-canopy forests from this study were consistent with values reported in the literature but were as much as 50% lower than values reported for old-growth stands. NPP predictions from three process models were fairly consistent with the FIA-based estimates, but model predictions of biomass were higher than estimates from FIA data for the region. By describing upper and lower bounds on reasonable biomass and NPP values for closed-canopy forests, these FIA-derived estimates provide a foundation for model comparison and continued model development.

The purpose of this experiment was to determine the maximum longevities of propagules from two common Pacific mangrove species: Rhizophora mucronata Lamk. and Rhizophora apiculata B1. Propagules from each of these species were placed in outdoor tubs with continuously flowing seawater. The condition of each propagule was monitored until it sank or started to rot. Propagules were then planted to determine viability. After planting, 50% of R. apiculata propagules and 21% of R. mucronata propagules were viable. For both species, mortality of propagules was strongly related to the length of the floating interval. Maximum longevities for R. mucronata and R. apiculata propagules were 150 (median = 70) and 89 days (median = 7), respectively. Rhizophora mucronata propagules appeared to be better equipped for long-distance dispersal, yet had low survivorship that would decrease overall dispersal opportunities. In comparison, R. apiculata propagules had higher survivorship yet shorter longevity and, thus, appeared to be better equipped for shorter distance dispersal.

The results from experiment (1) indicated that the amount of extractable NO super(-) sub(3) from isolated sand, silt and clay fractions increased with atmospheric concentration and duration of exposure. After 32 days, the highest absorption of HNO sub(3) was determined for clay, followed by silt and sand. While the sand and silt fractions showed a tendency to saturate, the clay samples did not after 32 days of exposure under highly polluted conditions. Absorption of HNO sub(3) occurred mainly in the top 1 mm layer of the soil samples and the presence of water increased HNO sub(3) absorption by about 2-fold. Experiment (2) indicated that the presence of coarse particulate NO super(-) sub(3) could effectively block absorption sites of soils for HNO sub(3) vapor. Experiment (3) showed that soil samples collected from open sites had about 2.5 more extractable NO super(-) sub(3) as compared to samples collected from beneath shrub canopies. The difference in NO super(-) sub(3) occurred only in the upper 1-2 cm as no significant differences in NO super(-) sub(3) concentrations were found in the 2-5 cm soil layers. Extractable NO super(-) sub(3) from surface soils collected from a low-pollution site ranged between 1 and 8 mu g NO sub(3)-N g super(-1), compared to a maximum of 42 mu g NO sub(3)-N g super(-1) for soils collected from a highly polluted site. Highly significant relationship between HNO sub(3) vapor doses and its accumulation in the upper layers of soils indicates that carefully prepared soil samples (especially clay fraction) may be useful as passive samplers for evaluation of ambient concentrations of HNO sub(3) vapor.

While many aspects of such ponds have been investigated, small mammal populations in the adjacent upland [catchment] habitat are largely unstudied. We selected three ponds in central Massachusetts to determine whether the presence of vernal ponds in forested habitat influences shrew species composition and abundance. Pitfall-trap arrays were installed in pond catchment basins and in adjacent upland forest habitat. A total of 2124 small mammals of nine species were captured during 3880 trap nights. Of these, 341 were shrews of three species. We found no significant differences in abundance between pond-side and upland habitat for any shrew species. In addition, no differences were found in structural and vegetation characteristics between habitats. While there may be some indication that vernal ponds provide some residual effects during dry periods, vernal ponds in the northeastern United States are small and highly variable in hydroperiod, apparently providing an unreliable resource for shrews.

Small mammals play many important roles in ecosystem functions, but little is known about small mammal community composition and structure in native bunchgrass habitats of the Northern Rocky Mountains. We live trapped small mammals along transects to study community composition, relative abundance, and habitat relationships in three native bunchgrass sites of west-central Montana. Small mammal community composition and relative abundance were consistent among sites, with deer mice (Peromyscus maniculatus) dominating, followed by montane voles (Microtus montanus), which were uncommon, and montane shrews (Sorex monticolus), which were rare. Deer mice and montane voles exhibited complementary habitat separation. Deer mice tended to select open microsites and avoid sites with high percentages of vegetative cover. Male and female deer mice demonstrated strong habitat separation at two sites, but the habitat variables partitioned between sexes differed by site. Montane voles avoided open sites and selected for concave microsites where the vegetative cover was relatively dense. This information provides an important baseline for understanding pre-settlement small mammal communities in the rapidly dwindling, native bunchgrass habitats of the Northern Rocky Mountains.

In this study we report flame emissive power and temperatures inside and outside fire shelters placed in one prescribed fire, five experimental field fires, and one laboratory fire. Energy levels radiated by flames varied from 70 to 150 kW m super(-2) and lasted less than 10 min. Maximum fire shelter internal air temperatures reached 250 degree C and occurred during the test with the maximum external air temperatures (1000 degree C). Air temperatures inside the fire shelters did not show a strong dependence on flame radiant power, rather they correlated most strongly with external air temperature. We compare measurements from these tests with results reported by others. The data clearly indicate (1) the capability of the fire shelter to protect the occupant from radiant heating; (2) the susceptibility of the current design to convective heating; and (3) the significant decrease in burn injury when fire shelters are used.

Pure cultures of fluorescent pseudomonads were isolated from three Mississippi Delta oxbow lakes (18 per lake), using selective media S-1. Classical physiological tests and Biolog GN plates were used in criteria for taxonomic identification. Most isolates were identified as biotypes of Pseudomonas fluorescens 55% (II), 7% (III), and 25% (V). About 7% of the isolates were identified as P. putida and 7% as non-fluorescent Pseudomonas-like. Cell suspensions of these isolates were tested for their ability to metabolize/co-metabolize six super(14)C-radiolabeled herbicides (2,4-dichlorophenoxyacetic acid (2,4-D), cyanazine, fluometuron, metolachlor, propanil, and trifluralin) that are commonly used for crop production in this geographical area. Almost all (53 of 54) isolates transformed trifluralin via aromatic nitroreduction. Most isolates (70%) dechlorinated metolachlor to polar metabolites via glutathione conjugation. About 60% of the isolates hydrolyzed the amide bond of propanil (a rice herbicide) to dichloroaniline, with the highest frequency of propanil-hydrolyzing isolates observed in the lake from the watershed with rice cultivation. All propanil-hydrolyzing isolates were identified as P. fluorescens biotype II. No metabolism of cyanazine or fluometuron was observed by any isolates tested, indicating little or no potential for N-dealkylation among this group of bacterioplankton. No mineralization of 2,4-D labeled in either the carboxyl or ring position was observed. These results indicate that reductive and hydrolytic pathways for herbicide co-metabolism (aromatic nitroreduction, aryl acylamidase, and glutathione conjugation) are common in Mississippi Delta aquatic fluorescent pseudomonads; however, the potential for certain oxidative transformations (N-dealkylation, cyano group oxidation) may be rare in this group of bacterioplankton.

AN - 17897593; 5125739 AB - Parent birds may adjust the onset of incubation to minimize periods of high risk of nest failure due to predation (the Nest Failure Hypothesis) or of mortality to adult birds (the Adult Predation Hypothesis). We examine temporal patterns of risk of nest failure and predation on adult females in a population of Green-rumped Parrotlets (Forpus passerinus) to determine whether those patterns explain observed patterns of incubation. Over one-third of nests (38.6%) failed completely, and an additional 2.2% failed after fledging one or more young. Most nests failed due to predation and infanticide. Because parrotlets begin incubation on the first egg, we examined a range of hypothetical failure rates for the period prior to the onset of incubation. Daily survival probabilities for nests were higher during the nestling stage than during incubation or fledging. Survival of adult females varied little through the nesting cycle, but was highest while attending nestlings. Model predictions were highly dependent on assumptions made about survival rates during the preincubation period. When empirically based values were used for this period, maximum productivity was achieved with first-egg incubation, consistent with observed patterns. Models were most sensitive to those parameters most difficult to estimate. This study represents the first test of the Nest Failure model with a nonpasserine or tropical species, and the first assessment of the Adult Predation model using field data.

We measured the pulp cavities and tooth widths based on radiographs of canine and premolar teeth from a large sample of known-age, pen-reared coyotes (Canis latrans) and from samples of wild-caught coyotes of unknown age. The ratio of pulp cavity to tooth width decreased rapidly through the first year of life. Although canine tooth ratios of juvenile, yearling, and adult coyotes differed, variations within yearling and adult groups precluded accurate assignment of individual coyotes to other than juvenile and mature age categories. A value of 0.45 in this ratio appeared to reasonably delineate the 2 groups among wild coyotes from northern Utah between November and February. Pulp cavity-tooth width ratios of upper canines and premolars were larger than ratios from lower canines and premolars from the same coyotes. Females had slightly smaller tooth ratios than males of the same age.

Seventy cavity inserts were installed in our study sites on the Angelina National Forest in eastern Texas from 1990 to 1995. Eighty-two percent of the inserts were used for at least one year. It is still too early to make a direct comparison, but it is likely that inserts will remain usable as long as natural cavities do. Inserts installed in 1990 and 1991 were 20.5 cm in height, whereas inserts installed from 1992 to 1995 were 25.5 cm in height. Larger inserts (25.5 cm) appear to remain usable for a longer time than smaller inserts (20.5 cm). Newer unused inserts are more likely to become active for the first time than older unused inserts. Similar to unused inserts, active cavities (naturally excavated and inserts) that have become inactive are less likely to be reactivated the longer they are inactive. Newness and recency of cavity use and red-cockaded woodpecker activity appear to be important factors in the attractiveness of inserts and naturally excavated cavities.

New products are continually becoming available, but their ability to repel deer is very variable. We tested 20 repellents representing 4 modes of action (fear, pain, taste, and aversive conditioning) and 2 delivery systems (topical applications and area repellents [scent packets]) to evaluate current products and identify trends that could be used to predict efficacy of future products. During fall 1998, we placed treated western red cedar (Thuja plicata) seedlings in pastures with black-tailed deer (Odocoileus hemionus) and recorded number of bites taken from each seedling at weekly intervals for 18 weeks. Four of the 5 most effective repellents used fear as a mode of action. We tested the 5 most effective repellents again in spring 1999 when trees were growing actively and were more palatable to deer. Only Plantskydd super(TM) and Deer Away Big Game Repellent registered powder reduced damage. However, unlike the winter study, the Deerbuster's super(TM) and Bye Deer registered sachets were hung on stakes at half the height of the seedlings instead of near the terminal buds. When an additional study was conducted with the sachets mounted near the terminal buds so that repellent could drip from bags onto the plants as in the winter study, Deerbuster's sachets and Bye Deer sachets reduced deer foraging. In general, products using fear as a mode of action were more effective than products using other modes of action and topical repellents were more effective than area repellents.

Carcass searches may occur over large areas and need to be completed rapidly because of scavenging and decomposition. However, small carcasses are often missed when dense vegetation is searched. We placed carcasses of house sparrows (Passer domesticus) in dense cover of residual and newly grown vegetation and compared searching efficiency of humans and canines. Dogs received no special training in searching for passerine carcasses. In 36 trials conducted in 5 X 40-m plots, human searchers found 45% (SD=19) of the carcasses compared to 92% (SD=13) for dogs (P=0.005). The ratio of recovered to missed carcasses was approximately 12:1 for dogs and 1:1 for humans. The improvement in searching efficiency using dogs was similar (P=0.58) between residual cover (searched in April) and new growth cover (searched in August). A greater rate of searching efficiency is obtained per unit of time by using dogs. Greater efficiency improves quantitative and qualitative assessments of avian mortality in the field.

Also, the range and efficiency of current video monitoring systems may be limited by the need to deploy video transmission cables, thereby increasing human disturbance and possibly affecting the behavior of nest predators. We describe a wireless video nest monitoring system that is much cheaper than currently available systems, can transmit up to 200 m in forest and 600 m in open habitats, and may reduce the influence of human disturbance on nest predator behavior.

Enterohemorrhagic E. coli, including E. coli O157:H7, can cause severe human diseases that can be debilitating and life threatening. Cattle are currently considered to be the definitive source for E. coli O157:H7 in the food supply, but this view may be simplistic and incomplete. E. coli O157:H7, appears widespread among U.S. cattle herds, while individual animal prevalence is low and transient. Most individual animals appear to be a transient reservoir for E. coli O157:H7 although the issue of carrier animals still remains unresolved. Epidemiological studies of the cattle production system have not clearly identified risk factors or management practices that affect E. coli O157:H7 prevalence in cattle feces. The problem of E. coli O157:H7 increases during the summer and fall months, but the environmental factors that contribute to this increase are poorly understood. Possible environmental factors that may influence E. coli O157:H7 shedding in cattle include livestock feed and waste handling practices as well as insects and microbial interactions in soil and water. Studies of E. coli O157:H7 ecology in cattle and the environment have been limited, but they suggest that a consideration of other independent, environmental sources of this microbe seems appropriate. The natural ecology of cholera may serve as a useful environmental model for pursuing additional environmental research on the occurrence and transmission of E. coli O157:H7 in nature.

This strategy has been unusually effective. In the United States, losses from the condemnation at slaughter of young broiler chickens with visible lesions of MD have decreased from 1.5% in 1970 to 0.0121% in 1999, a reduction of over 99% (Fig. 1). Even more dramatic reductions are evident in Georgia and Delaware, states with intensive broiler production. Similar benefits have been realized in commercial layer and breeder flocks. Vaccination for the control of MD in the field has been one of the great successes in veterinary medicine. Epidemiological characteristics of infection with MD virus (MDV) include shedding of enveloped, infectious viral particles from the feather follicle, rapid horizontal transmission by aerosol routes, and survival of infectivity in the environment for weeks to years, depending on conditions. Infection is ubiquitous and can be devastating in unvaccinated chickens, producing up to 60% mortality within a few weeks. Vaccination protects against tumor induction and mortality but does not prevent viral replication or shedding. Therefore, most poultry environments are heavily seeded with fully infectious MDV, and exposure at relative early ages is typical. If there was no vaccination against MD, the poultry industry would not exist in its present form. The presence of this universal lethal challenge and continued evolution of the virus towards greater virulence warrant continued vigilance and concern.

To compare the depredation of these surrogates to that of the eggs of a mid-sized passerine by a ubiquitous small predator, we exposed dissimilar pairs of plasticine, Zebra Finch, and House Sparrow (Passer domesticus) eggs to captive white-footed mice (Peromyscus leucopus). Plasticine eggs were marked by mice more than either kind of real egg, and Zebra Finch eggs were breached more often than House Sparrow eggs. We conclude that the use of either plasticine or Zebra Finch eggs may lead to overestimation of the ability or proclivity of small mammals to actually depredate the eggs of most passerines.

Isotopic labeling with super(15)N nitrate together with amino acid analysis and mass spectrometry was used to assess the free amino acid pools of root and shoot tissues in colonized plants (M) compared to uncolonized plants grown either with (NM+P) or without (NM-P) supplemental phosphate. Total amino acid levels in roots were lower in M than in NM-P plants and this effect also was induced partially in NM+P plants by supplemental phosphate. The relative proportions of different amino acids were not affected by the AM symbiosis nor were amino acid levels in leaves affected by either colonization or increased phosphate supply. Fractional labeling was substantial in all free amino acids after a six-week labeling period and enrichments were higher on average in M than in NM-P. There were no indications of effects of mycorrhizas upon relative enrichments in different amino acids. However, a higher incorporation of label was found in Asp, Glu, and Gln in short term super(15)N labeling experiments (72 h) with M than NM-P plants. The average labeling in all amino acids was higher in the roots of M plants. More rapid turnover of amino acids was noted in the M plant roots, however this was probably due to the lower concentration of amino acids found in the plant. These results suggest that there are indeed effects of AM symbioses on overall nitrogen handling by the host but that these are secondary effects of the improved phosphate supply to the host and do not cause significant shifts in levels or fluxes through different amino acids.

One adult, male bobcat (Felis rufus) with histologic lesions suggestive of tuberculosis was negative on culture but positive for organisms belonging to the Mycobacterium tuberculosis complex when tested by polymerase chain reaction. All the tuberculous animals were taken from three adjoining counties where M. bovis is known to be endemic in the free-ranging white-tailed deer (Odocoileus virginianus) population. There were two coyotes, one raccoon, one red fox, and one bobcat infected in Alpena county. Montmorency County had two coyotes and one raccoon with M. bovis. Two coyotes and a bear were infected from Alcona County. These free-ranging carnivores/omnivores probably became infected with M. bovis through consumption of tuberculous deer. Other species included in the survey were opossum (Didelphis virginiana), gray fox (Urocyon cinereoargenteus), and badger (Taxidea taxus); these were negative for M. bovis.

One adult animal with a retained placenta had recently aborted. Serum samples from the 35 juvenile and adult bison were tested for Brucella spp. antibodies. Twenty-six bison, including the cow with the retained placenta, were seropositive, one was suspect, and eight were seronegative. Brucella abortus biovar 1 was isolated from three aborted fetuses and associated placentas, an additional placenta, the 2-wk-old calf, and 11 of the seropositive female bison including the animal that had recently aborted. Brucella abortus biovar 2 was isolated from one additional seropositive adult female bison. Brucella abortus was recovered from numerous tissue sites from the aborted fetuses, placentas and 2-wk-old calf. In the juvenile and adult bison, the organism was more frequently isolated from supramammary (83%), retropharyngeal (67%), and iliac (58%) lymph nodes than from other tissues cultured. Cultures from the seronegative and suspect bison were negative for B. abortus. Lesions in the B. abortus-infected, aborted placentas and fetuses consisted of necropurulent placentitis and mild bronchointerstitial pneumonia. The infected 2-wk-old calf had bronchointerstitial pneumonia, focal splenic infarction, and purulent nephritis. The recently-aborting bison cow had purulent endometritis and necropurulent placentitis. Immunohistochemical staining of tissues from the culture-positive aborted fetuses, placentas, 2-wk-old calf, and recently-aborting cow disclosed large numbers of B. abortus in placental trophoblasts and exudate, and fetal and calf lung. A similar study with the same tissue collection and culture protocol was done using six seropositive cattle from a B. abortus-infected herd in July and August, 1997. Results of the bison and cattle studies were similar. JF - Journal of Wildlife Diseases AU - Rhyan, J C AU - Gidlewski, T AU - Roffe, T J AU - Aune, K AU - Philo, L M AU - Ewalt AD - U. S.

When mortality and wood consumption rates of 6 colonies of each termite species were compared, overall wood consumption rates of C. formosanus were greater than rates of R. flavipes, and overall mortality rates of R. flavipes were greater than rates of C. formosanus. When the effects of block size on wood consumption rates were examined, wood consumption rates of R. flavipes were much greater on the large blocks than on the small blocks; however, wood consumption rates of C. formosanus were not affected by block size. When the effects of test duration on wood consumption rates were examined, wood consumption rates of both termite species were greater in 10 day tests than in 28 day tests. C. formosanus tended to build wider tunnels than R. flavipes and showed a greater foraging tenacity than R. flavipes when termites were allowed to become established on a food source before being given access to a second food source. Differences in total tunneling areas constructed by C. formosanus colonies were positively correlated with average worker biomass. There were no significant differences between species or colonies in length of time taken to find food; however, there was a great deal of variability between replicates, with time taken to find food ranging from < 24 h to 7 d. Neither species demonstrated any ability to detect the presence of a sound block of wood when tunneling through sand.

Two compounds, ethyl isovalerate and limonene, were significantly attractive in both laboratory bioassays and field experiments. In laboratory bioassays, as concentration was decreased across five orders of magnitude, a greater number of compounds elicited responses suggestive of attractancy (except at the lowest concentration). Even so, linalool, 2-hexanone, and 3-hydroxy-2-butanone were the only other compounds showing significant attractiveness in laboratory bioassays, but none of these (nor any other compounds) were significantly attractive in field assays. We suggest that the use of ethyl isovalerate and/or limonene as odor attractants offers potential to increase the efficacy of current traps for monitoring PCs immigrating into fruit orchards during spring.

Prey found in D. coloradensis webs were assigned to one of three categories: pests, predators and parasitoids, or neutral in impact with respect to fruit trees. Pest taxa comprised 32%, predators and parasitoids 24%, and neutral groups 44% of 18,314 prey. Most prey were small, winged insects (length < 5 mm). Insects from 58 families in 10 orders were represented and small spiders in four families were occasionally trapped. Sciaridae and Chironomidae (Diptera) were the most numerous prey and made up 37% of the total. Most webs contained one or more of these flies and occasionally 25 or more were trapped. Alate aphids were the most frequently captured pest insects. Other pests included adults of the white apple leafhopper, the pear psylla, and thrips. Relatively non-mobile stages of the pests (leafhopper and pear psylla nymphs and apterous aphids) were less commonly found in the webs. Nineteen percent of all prey were parasitoid wasps, 14 families of which were identified. Known parasitoids of apple and pear pests were included. The only other predator or parasitoid taxon that comprised more than 1% of total prey was the Empididae (3%).

Don) Spach) in Prince William Sound, Alaska; even the northwest limit of the range of this valuable tree has been unresolved. Mapping the occurrence of yellow-cedar from aircraft, boat, and by foot revealed two general locations: small populations on or near Hawkins Island and larger and more extensive populations from Glacier Island to Cedar Bay, Wells Bay, and Unakwik Inlet. A population of yellow-cedar on the eastern shore of Unakwik Inlet represents the furthest known northwest extent of the natural range. Results from plots located in the eastern and north-central areas of Prince William Sound indicate that yellow-cedar is common in all diameter classes, but is younger than the associated western hemlock (Tsuga heterophylla (Raf.) Sarg.) and mountain hemlock (T. mertensiana (Bong.) Carr.). The tree is reproducing prolifically in the north-central portion of the sound. Reproduction, growth, and the vigorous appearance of trees suggest that yellow-cedar is currently thriving and increasing in abundance near the edge of its range. Direct human use of these forests has been limited to the harvesting of small diameter trees and the common occurrence of bark removal on the larger yellow-cedar trees.

We sampled populations at 42 stream sites and eight upland sites within a 100-km super(2) watershed in 1995 and 1996. Stream reaches sampled ranged from poorly defined channels that rarely flowed to 10-m-wide channels with perennial flow. The majority of reaches flowed only intermittently. Aquatic vertebrates were sampled by conducting area-constrained surveys, and terrestrial vertebrates were sampled along three 45-m-long transects using cover boards, drift fence/pitfall trap arrays, and two types of live trap. Vegetation characteristics were strongly associated with measures of stream size, especially channel width. Compared to upland sites, mean numbers of plant species in the herbaceous layer were significantly greater along-streams with active channel widths as small as 0.9-1.3 m. Larval Pacific giant salamanders (Dicamptodon tenebrosus) were found only in stream reaches with continuous flow or in channels greater than or equal to 2.4-m wide, and larval tailed frogs (Ascaphus truei) were found only at sites with continuous or nearly continuous flow. Allen's chipmunks (Tamias senex) and deer mice (Peromyscus maniculatus) occurred at nearly every site sampled but were more abundant at reaches along larger streams than at reaches along smaller streams or at upland sites. None of the vertebrate species evaluated was significantly associated with intermittent streams having channels less than about 2-m wide and drainage areas less than about 10 ha. Our results provide additional information on the ecological role of small, intermittent streams.

Critical shear stress and k sub(d) are used to define the erosion resistance of the streambed. The jet-testing apparatus applies hydraulic stresses to the bed and the resulting scour due to the impinging jet is related to the excess stress parameters. Streams tested were primarily silt-bedded in texture with low densities, which is typical of loess soils. Results indicate that there is a wide variation in the erosion resistance of streambeds, spanning six orders of magnitude for tau sub(c) and four orders of magnitude for k sub(d). Erosion resistance was observed to vary within a streambed, from streambed to streambed, and from region to region. An example of the diversity of materials within a river system is the Yalobusha River Basin in Mississippi. The median value of tau sub(c) for the two primary bed materials, Naheola and Porters Creek Clay Formations, was 1.31 and 256 Pa, respectively. Streambeds composed of the Naheola Formation are readily eroded over the entire range of shear stresses, whereas only the deepest flows generate boundary stresses great enough to erode streambeds composed of the Porters Creek Clay Formation. Therefore, assessing material resistance and location is essential in classifying and modelling streambed erosion processes of these streams.

The identities of extra-integron genes encoding resistance to streptomycin, gentamicin, kanamycin, and apramycin were evaluated. Gentamicin resistance was conferred by the aadB gene. Kanamycin resistance was encoded by either the aphA1-Iab gene or the Kn gene. Apramycin resistance was determined by the aacC4 gene. Analysis of gene distribution did not reveal significant differences with regard to phage type, host species, or region except for the Kn gene, which was found mostly in nonclinical isolates. The data from this study indicate that pentaresistant DT104 does not acquire extra-integron genes in species- or geography-related foci, which supports the hypothesis that clonal expansion is the method of spread of this organism.

Despite the fact that the phenazine biosynthetic locus is highly conserved among fluorescent Pseudomonas spp., individual strains differ in the range of phenazine compounds they produce. This study focuses on the ability of Pseudomonas aureofaciens 30-84to produce 2-hydroxyphenazine-1-carboxylic acid (2-OH-PCA) and 2-hydroxyphenazine from the common phenazine metabolite phenazine-1-carboxylic acid (PCA). P. aureofaciens 30-84 contains a novel gene located downstream from the core phenazine operon that encodes a 55-kDa aromatic monooxygenase responsible for the hydroxylation of PCA to produce 2-OH-PCA. Knowledge of the genes responsible for phenazine product specificity could ultimately reveal ways to manipulate organisms to produce multiple phenazines or novel phenazines not previously described.

Roosts for both age-classes were located in cavities and under exfoliating bark in live trees and dead snags. Based on nightly exit counts, adult female evening bats roosted communally. Some roosts were presumed to be active maternity colonies. Five of six subadult roosts and one adult female roost were located under exfoliating bark on dead snags in beaver (Castor canadensis) ponds. Thirteen of 14 adult female evening bat roosts were located in cavities in live longleaf pines (Pinus palustris) in stands of relatively mature, park-like, pine plantations. One subadult roost was located under exfoliating bark in a live longleaf pine. No evening bats roosted in the more densely canopied, nearby bottomland hardwood stands, mixed pine-hardwood stands or loblolly pine (P. taeda) stands. Roost fidelity by individual evening bats was short (2.3 roost-days per bat) and did not differ between subadults and adult females. Although average daily maximum roost temperature was higher in subadult roosts than in adult female roosts, internal average temperature, daily minimum temperature and daily temperature range did not differ significantly between the two roost categories. Overstory height surrounding roost trees, canopy density and basal area of pine in the surrounding stand were greater at roosts within longleaf pine stands than those in beaver ponds. Conversely, stand basal area, overstory tree species richness, abundance of Spanish moss (Tillandsia usneoides) and basal area of hardwood trees were greater at roost sites within beaver ponds than those same measures in longleaf pine stands.

Lag ex Griffiths (blue grama). The importance of soil texture, grazing by cattle, disturbance type and severity were evaluated. Two disturbance types (covering or removing tillers) and three disturbance severities (50, 75 and 90% tiller mortality) were used to represent effects of natural disturbances in shortgrass communities (cattle fecal pats, nest sites of Western harvester ants, burrows of small animals). Tiller survival was not affected by soil texture or grazing intensity, but was affected by disturbance type and severity. Plants that were covered showed a 33% increase in tiller survival for all levels of disturbance severity from August (1991) to June (1992). No net change in tiller number was observed for removed or reference plants. Different responses between disturbance types were likely due to increases in root:shoot ratios of covered plants that increased tiller production as a result of increased soil water acquisition. The number of tillers produced was small, but statistically significant (average = 20 tillers/plant), which shows that B. gracilis plants do not produce independent tillers, but consist of integrated physiological units (IPUs). The lack of plant mortality, even with 90% tiller mortality, indicates that small disturbances must kill entire plants before gaps in resource space are produced to initiate gap dynamics that result in the recovery of an individual B. gracilis plant. Because recovery through seedling establishment by B. gracilis occurs infrequently, the ability of this species to survive after partial plant mortality is important to its continued dominance of shortgrass steppe communities in the presence of these small but frequent disturbances.

No seedlings were planted in one-half of the area of each plot. No seedlings survived in the black grama grassland or the creosotebush shrubland 2 years after planting. Growth of established creosotebush shrubs was highest in plots with the lowest grass cover. Fifteen years after the seedlings were planted in the overgrazed grassland, the area under the shrubs was nearly devoid of perennial grasses and forbs. The aggregate stability of the soils under the established creosotebush shrubs was significantly lower than the soils in the unplanted split-half of the plots. Electrical conductivity, calcium, and nitrate were significantly lower in soils under shrubs than soils in the unplanted split-half of the plots. There were also significant reductions in densities of annual plants growing under the shrubs than in the unplanted split-half of the plots. Successful establishment of creosotebush in desert grasslands is dependent upon the presence of large patches of soil with no perennial plant cover. Intense grazing by domestic livestock creates microsites and landscape characteristics favourable for seed dispersal, germination and establishment of creosotebush.

Tropical and subtropical species offer the opportunity to study the effects of low temperature on photosynthetic processes undisguised by the myriad of protective responses observed in temperate species. In this article, we highlight the primary components of photosynthesis that are affected by a short chill, in both the dark and the light, and discuss what is known of the mechanisms involved. Recent work implicates impaired redox and circadian regulation among other processes.

This spruce beetle outbreak is the largest recorded in Utah history. An extensive ground survey was conducted in 1996 on the Manti-LaSal National Forest, Sanpete and Ferron Ranger Districts, to document mortality and impact of a major spruce beetle outbreak on post-outbreak forest composition. In 1998 the same sites were resurveyed. Survey results indicate Engelmann spruce basal area (BA) loss averaged 78% in trees greater than or equal to 5 inches diameter breast height (DBH) in 1996. Ninety percent of BA greater than or equal to 5 inches DBH was lost within the same sites by 1998. Tree mortality of spruce greater than or equal to 5 inches DBH expressed in trees per acre (TPA) averaged 53% in 1996. In 1998 TPA greater than or equal to 5 inches DBH mortality averaged 73%. Before the outbreak live Engelmann spruce BA greater than or equal to 5 inches DBH averaged 99 square feet, and TPA greater than or equal to 5 inches DBH averaged 97. In the sites surveyed in 1996 and resurveyed in 1998, Engelmann spruce BA greater than or equal to 5 inches DBH averaged 21 and 9 square feet, and TPA greater than or equal to 5 inches DBH averaged 43 and 25, respectively. Overstory tree species composition changed from stands dominated by spruce to subalpine fir. Stand ratings for potential spruce beetle outbreaks were high to mostly medium hazard pre-outbreak and medium to primarily low hazard by 1998, as a result of reduction in average spruce diameter, total basal area, and overstory spruce.

Because of the known toxicity of arsenic and the fact that there is considerable evidence from studies in rats, hamsters, chicks, minipigs, and goats that arsenic is an essential element, more detailed studies of the effect of arsenic on copper seemed appropriate. Therefore, an experiment was designed to study the possible interaction between arsenic and copper. The experiment used male weanling Sprague-Dawley rats in a two factor, three-by-three design with dietary variables arsenic (supplemented as As sub(2)O sub(3) at 0, 0.5, or 50 mu g/g) and copper (supplemented as cupric carbonate at 1, 6, or 25 mu g/g). At 62 days, various parameters were measured. The results confirm earlier findings showing that high dietary arsenic causes a marked accumulation of copper in the kidney of rats. Additionally, the results suggest that high dietary arsenic can exacerbate signs of copper deficiency. For example, heart weight/body weight ratio and the concentration of liver iron were increased by copper deprivation, and both parameters were further increased in rats fed 50 mu g arsenic/g diet. Also, in rats fed high dietary arsenic, ceruloplasmin was markedly decreased in rats fed 1 or 6 mu g copper/g diet compared to rats fed 25 mu g copper/g. The mechanism for the apparent exacerbation of copper deficiency by high arsenic is not known.

The rumen of these animals is basically an anaerobic fermentation vat in which the microflora break down the complex polysaccharides of plant cell walls into simpler compounds that can be further digested and absorbed by the mammalian digestive system. Research on improving the forage digestibility of switchgrass, Panicum virgatum L., and other herbaceous species has demonstrated that genetic improvements can be made in forage quality that can have significant economic value. To meet future energy needs, herbaceous biomass will need to be converted into a liquid fuel, probably ethanol, via conversion technologies still under development. If feedstock quality can be genetically improved, the economics and efficiency of the conversion processes could be significantly enhanced. Improving an agricultural product for improved end product use via genetic modification requires knowledge of desired quality attributes, the relative economic value of the quality parameters in relation to yield, genetic variation for the desired traits, or for molecular breeding, knowledge of genes to suppress or add, and knowledge of any associated negative consequences of genetic manipulation. Because conversion technology is still under development, desirable plant feedstock characteristics have not been completely delineated. Some traits such as cellulose and lignin concentration will undoubtably be important. Once traits that affect biomass feedstock conversion are identified, it will be highly feasible to genetically modify the feedstock quality of herbaceous plants using both conventional and molecular breeding techniques. The use of molecular markers and transformation technology will greatly enhance the capability of breeders to modify the morphologic structure and cell walls of herbaceous species. It will be necessary to monitor gene flow to remnant wild populations of biomass plants and have strategies available to curtail gene flow if it becomes a potential problem. It will also be necessary to monitor plant survival and long-term productivity as affected by these genetic changes to herbaceous species.

This whitefly is also a vector of more than 70 plant-infecting viruses. A cell line was established in vitro using embryonic tissues from the eggs of Bemisia tabaci (Gennadius), B biotype (pseudonym B. argentifolii Bellows & Perring), and referred to as 'Btb(Ba)97, Hunter-Polston'. Cell cultures were successfully inoculated with begomovirus (BGMV and ToMoV)-infected tomato plant sap. Embryonic tissues were seeded into Kimura's modified medium and kept at a temperature of 24 degree C. Continuous cell cultures were established and have since undergone 92 passages in 25-cm super(2) flasks. Cell doubling time is approximately 3 days and the cells have been successfully revived after 1 year after storage at -80 degree C. The cell population is monolayers of predominately fibroblast with some epithelial cells. Begomoviruses (bean golden mosaic begomovirus, BGMV, and tomato mottle begomovirus, ToMoV) were inoculated to the cell cultures independently and detected by labeling by an indirect immunofluorescence technique. The viruses were detected bound to the cell membranes and within the cell cytoplasm. This is the first report of a continuous cell line established from a species of whitefly and its inoculation with two begomoviruses. The successful inoculation of whitefly cell cultures with begomoviruses shown in our results represents great promise for the development of systems that allow researchers to achieve a better understanding of the complex relationship between begomoviruses and their whitefly vectors.

Numerous laboratory studies have demonstrated that Bt and Bt products are noninfectious and are toxic to mammals only at a dose greater than or equal to 10 super(8) colony forming units (cfu) per mouse (a human equivalent based on the weight of >10 super(11) cfu). In contrast, as few as three vegetative cells of Bacillus anthracis can kill mice (a human equivalent of >10 super(3) cfu). There are only two literature reports of Bt infection in man between the year 1997 and the present, and all infected individuals had experienced either extensive burns or a blast injury, which predisposed them to infection. Two epidemiology studies conducted during large-scale aerial Bt serovar kurstaki spray campaigns reported no increased incidence of illness. Some recent papers have expressed concern about the production of Bacillus cereus enterotoxins by Bt isolates. Laboratory studies found no evidence of illness in rats and sheep fed Bt products, nor have epidemiology studies found increased incidence of diarrhea during Bt aerial spray campaigns. Increases in human antibody levels following exposure to Bt products have been reported but there was no increased incidence in asthma or other illness. Based on laboratory studies and field experience, Bt insecticides have an excellent safety record.

We studied populations of spores of VAM fungi, mycorrhiza formation and nutrient utilization of maize (Zea mays L.) grown in moldboard plowed, chisel-disked or no-tilled soil under conventional and low-input agricultural systems. Maize shoots and roots were collected at four growth stages. Soils under low-input management had higher VAM fungus spore populations than soils under conventional management. Spore populations and colonization of maize roots by VAM fungi were higher in no-tilled than in moldboard plowed or chisel-disked soil. The inoculum potential of soil collected in the autumn was greater for no-till and chisel-disked soils than for moldboard plowed soils and greater for low-input than conventionally farmed soil. The effects of tillage and farming system on N uptake and utilization varied with growth stage of the maize plants. The effect of farming system on P use efficiency was significant at the vegetative stages only, with higher efficiencies in plants under low-input management. The effect of tillage was consistent through all growth stages, with higher P use efficiencies in plants under moldboard plow and chisel-disk than under no-till. Plants grown in no-tilled soils had the highest shoot P concentrations throughout the experiment. This benefit of enhanced VAM fungus colonization, particularly in the low-input system in the absence of effective weed control and with likely lower soil temperatures, did not translate into enhanced growth and yield.

The incidence of sour rot, caused by Geotrichum citri-aurantii, was reduced 35-70% by this treatment. LLS was similar in effectiveness to other treatments employed to control postharvest decay. Effectiveness was higher on lemons than oranges, and on green compared to yellow lemons. LLS did not stop sporulation, a benefit now obtained with some fungicides. The sulfide content of oranges, lemons, and grapefruit after LLS treatment was 31.9, 33.1, and 36.3 mu g g super(-1), respectively. Rigorous cleaning of fruit with water applied at high pressure after LLS treatment slightly improved LLS efficacy; conversely, similar cleaning reduces the efficacy of sodium carbonate or borax-boric acid solutions now in use. The risk of injury to fruit by LLS was low. Fruit of one lemon and five navel orange cultivars were not visibly injured after LLS treatment for 3 min at 40.6 degree C followed by storage for 7 weeks at 10 degree C. After LLS treatment at 48.9 degree C, 5 degree C higher than needed for effective LLS use, only Lisbon lemons and Bonanza navel oranges were slightly injured. Sulfide concentration in LLS solution declined at a rate of about 7% every 24 h, this rate was similar between 25 and 65 degree C, and it was accompanied by the appearance of resistant deposits on the equipment. Additional losses would occur when some LLS solution is carried on fruit out of the tank. Although H sub(2)S in the air above LLS solution in pilot tests was less than 1 mu l l super(-1) and below the worker safety threshold of 10 mu l l super(-1), LLS solution has an odor of H sub(2)S that can be a nuisance to workers. The disposal of used LLS solutions is more readily accomplished than other tank treatments whose disposal can be difficult because they contain synthetic fungicides, are caustic, or have a high salt concentration. Because LLS improves water penetration in soils and is commonly used for this purpose, in many locations it can be disposed of by application to agricultural soils.

Several states have tried to establish general threshold soil P levels above which the enrichment of surface runoff P becomes unacceptable. However, little information is available on the relationship between soil and surface runoff P, particularly for the northeastern United States. Further, threshold soil P criteria will be of limited value unless they are integrated with site potential for runoff and erosion. In response, the Natural Resource Conservation Service (NRCS) developed a P Index (PI), which ranks the vulnerability of fields as sources of P loss in runoff, based on soil P, hydrology, and land use. This study evaluated the relationship between soil and surface runoff P in a study watershed in central Pennsylvania. The relationship was then incorporated into the (PI), and its impact on the identification of critical source areas within the watershed was examined. Using simulated rainfall (6.5 cm -1 for 30 min), the concentration of dissolved P in surface runoff (0.2-2.1 mg l super(-1)) from soils was related (r super(2)=0.67) to Mehlich-3 extractable soil P (30-750 mg kg-1). Using an environmentally based soil P threshold level of 450 mg kg-1 determined from the soil-runoff P relationship, the PI identified and ranked areas of the watershed vulnerable to P loss. The vulnerable areas were located along the stream channel, where areas of runoff generation and areas of high soil P coincide, and where careful management of P fertilizers and manure should be targeted.

In an attempt to identify new sources of resistance to the fruit rot (mummification) phase of mummy berry, 140 accessions from a total of 21 populations from seven wild diploid species of blueberry were evaluated for resistance under greenhouse conditions. Six isolates of M. vaccinii-corymbosi from three states were used as inoculum. A highly resistant response to mummy berry fruit rot was exhibited by all accessions of Vaccinium boreale, V. myrtilloides, V. pallidum, and V. tenellum, and by most accessions of V. darrowi. Most of the V. corymbosum and V. elliottii accessions were moderately to highly susceptible. Introgression of the resistance found in the wild diploid species into horticulturally desirable cultivars could significantly improve available resistance.

Plants were grown from seed in sand infested with the sailborne pathogen Monosporascus cannonballus, Acremonium cucurbitacearum, or Rhizopycnis vagum. After 28 days in the growth chamber, images of plants were analyzed to quantify their response. Compared to noninoculated muskmelons, inoculated plants had significantly increased mean root diameter (45%), decreased root length (26%, primarily in roots of <0.5 mm diameter), decreased number of root tips (27%), decreased rhizosphere volume (40%), and decreased cumulative and mean surface area of leaves (24%). Effects of M. cannonballus on muskmelon growth were significantly different compared to A. cucurbitacearum and R. vagum. Isolate effects manifested a greater magnitude of difference on muskmelon traits than those observed at the species level. Multivariate analyses of plant responses were more powerful than univariate analyses to differentiate among effects of pathogen species and pathogen isolates. Discriminant analysis were useful to identify groups of plant traits modified by each fungal species or isolate at low disease levels. Digital image analyses proved to be a useful technique in quantitative assessment of plant damage caused by soilborne root rot pathogens.

Nationally, the responsibility for safeguarding agriculture falls to the U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Plant Protection and Quarantine (USDA, APHIS, PPQ). However, the current system for protecting agricultural industries has broken down allowing for an unprecedented number of introductions of exotic pests, including plant pathogens. Such introductions threaten crops and can hinder national and international agricultural markets and trade. In 1999, President Clinton announced an initiative for invasive species to address these issues and introduced an Executive Order on Invasive Species. The order is intended to coordinate and enhance federal government efforts to prevent introduction of invasive species and to provide for their control. The Executive Order calls for the appointment of a council, chaired by the Secretaries of Agriculture, Commerce, and the Interior, and composed of key federal agencies charged with developing an invasive species management plan. In response, the National Plant Board initiated a "stakeholder" review of the USDA, APHIS, PPQ safeguarding system in order to identify means to improve pest exclusion and detection of and response to invasive pest introductions.

In a broth microdilution assay against nine ovine pathogens, SMAP29, SMAP34, mouse CRAMP, CAP18, CAP18 sub(31), CAP18 sub(28), CAP18 sub(22), and CAP18 sub(21a) were the most active, with MICs as low as 0.6 mu g/ml. Other cathelicidins were less active. In lambs with pneumonia, 0.5 mg of SMAP29 reduced the concentration of bacteria in both bronchoalveolar lavage fluid and consolidated pulmonary tissues. Hence, the antimicrobial activity of SMAP29 suggests that it has applications in the treatment of respiratory tract infections.

Under constant-temperature conditions, time from infection to 50% of pustules erupted for perennial ryegrass ranged from 54 days at 3.5 degree C to 5.9 days at 26.5 degree C. The latent period (LP sub(50)) duration of tall fescue was 69 and 8.5 days at these respective temperatures. The dependence of latent-period completion rate on temperature was best described as a linear increase in rate with temperature up to approximately 26 degree C, then an exponential decline with temperature up to the maximum (lethal) temperature of approximately 35.5 degree C. LP sub(20), the time required for 20% of open pustules to appear, was used as an estimator of latent-period duration for field observations. Percentage of one latent period completed per half hour (half-hourly rate), for perennial ryegrass was modeled as (0.0156T - 0.0206) {1 - exp[0.497(T - 35.5)]}, where T = average temperature ( degree C) during the half-hour period. For tall fescue the modeled rate was (0.0109T- 0.00214) {1 - exp[0.417(T- 35.5)]}. Latent periods modeled by these equations were compared with observed latent periods in field experiments with potted plants, where half-hourly temperatures were measured. Linear regressions of modeled versus observed latent periods had adjusted r super(2) values of 0.96 for perennial ryegrass and 0.93 for tall fescue. The latent-period equations could be used as components of a weather-based disease advisory model to optimize fungicide use in stem-rust management on these crops.

The aim of research was to specify soil structure of the Belianske Tatry Mts, as well as to study soil interactions with substrate, plant communities and influence of man. The most significant factor effecting soil structure are calcareous and silicate-calcareous rocks. They caused formation of Rendzic Leptosols and Calcaric Cambisols in 43% of area and eliminated vertical soil zonation. The least various soil condition were in northwestern, northern and southwestern parts of the mountains, where Cambisols prevail, which are the most extended soils in Belianske Tatry Mts (about 33.5%). The climate and vegetation affect soil structure especially by decarbonization of the surface layer, so despite of calcareous rocks, some more acid soil may be formed. Although 57% of investigated soils have origin in calcareous, or calcareous-silicate parent rock, only 36% of soils have neutral reaction. The tourism causes especially water erosion, which less deep and humic soils are subduing to. Shallow and stony soils with low content of fine earth are rather immune.

They have a limited migration ability and a comparatively quick reproduction cycle. Therefore, they may be easily exposed to the EM fields during several generations. The results has proved the intensive impact of the EM fields, mainly on the ecological structure, composition of the communities, and on the morphological, physiological and ethological phenomena of some selected species. The insects communities in our research were for a long period to the EM waves with the intensity of the electrical field higher than 100-150 V/m, that is the natural electrical field of the Earth's atmosphere, and to the magnetic field with the intensity higher, than 32-56 A/m. The EM fields cause the long-term changes in the species distribution in the terrestrial ecosystems. The species compositions were also compared with those existing in the non-stressed regions, which are considered to be typical for their natural habitats.

Management of brown tree snakes is aimed at a number of objectives, the foremost of which has been to deter its dispersal through Guam's cargo traffic to other locations. Another objective is to reclaim areas on Guam for reintroduction of native wildlife. A related objective is the protection of small sensitive sites on Guam from brown tree snake intrusion, such as power stations or nesting trees and caves. A fourth objective is to contain and capture incoming brown tree snakes at destinations vulnerable to their introduction. A final objective is to control incipient populations in other areas beyond their native range. A number of control tools have been developed, or are being developed. The efficacy of each control method depends on the situation to which it is to be applied. The control methods are described individually and the suites of methods most suited to each management objective are discussed.

House Sparrow eggs can be readily collected in quantity by providing nest boxes in active livestock barns. We collected over 1200 eggs in three years (320-567 per year) from a colony of about 24 breeding pairs by providing 60 nest boxes. Eggs dry-refrigerated at 8-9 'C lost mass after 2 weeks, whereas eggs submerged in sodium silicate solution at 8-9 'C remained fresh for 2 months until deployment. Eggs stored in sodium silicate solution should be rinsed with clean water before use.

It consists of the localities Horny les and Dolny les on the alluvium of the Morava river left bank and Kobyliarka elevation between the villages Borsky Svaety Jur and Laksarska Nova Ves Sandy (arenic) soils are spread on the area of 9052 ha (33% of the whole area). They are developed on eolian and alluvial sediments. They are without carbonates, what is the reason of their acidity. Soil acidity is increased from Mollic Fluvisols (CAm), Eutric Fluvisols (FMm), Dystric Regosols (RMm) to Haplic Podzols (PZm) in the catena of natural arenic soils without significant anthropic influences as cultivation, fertilization and liming are a result of pedogenetical processes. The lowest content of humus in very shallow humic horizon (0.2 m) was determined in Dystric Regosols (RMm). It corresponds to the composition of vegetation type Thymo angustifolii-Corynephoretum canescentis Krippel 1954 with low biomass production of the herb layer, which was determined in the area "Vo Vrskoch" near the village Laksarska Nova Ves. Eutric Fluvisols (FMm) in the locality "Cierny les" in the distric of the village Gajary has a deeper humic horizon (0.5 m), with higher content of humus. It was developed in the process of humification of plant residues of vegetation. The highest biomass production of the plant community type Pleurozio schreberi-Pinetum, Somsakova 1988, with higher biomass production of the herb layer. Highest biomass production of phytocoenose Fraxino-pannonicae-Ulmetum Soo in Aszod 1936 corr. Soo in deep humus horizon creation (0.9 m) of soil type Mollic Fluvisols (CAm). This soil has the highest content of humic substances of high quality from arenic soils on the locality "Siroke" near by the village Vysoka pri Morave.

Metabolized isoproturon, in the media, ranged from 0% (Chlorella at pH 5.5 after 1 d) to 22% (Anabaena at pH 5.5 after 10 d). Twenty-five percent faster degradation of isoproturon by Anabaena occurred at pH 5.5 versus pH 7.5, when measured over 10 d. Increased super(14)C incorporation into tissue, with time and at lower pH, was due mainly to bioaccumulation of [ super(14)C]isoproturon and/or its metabolites in the cells. Metabolic degradation resulted in four identifiable (by TLC) metabolites. Based on this, a degradation pathway is proposed, involving mono- and di-N-demethylation, hydroxylation of the isopropyl moiety, and hydrolysis to 4-isopropylaniline. Similarity in the metabolites produced suggests that the enzyme systems responsible for metabolizing isoproturon are almost identical in both photosynthetic micro-algae.
