N1 - Last updated - 2011-10-26 ER - TY - JOUR T1 - Lymphocyte subset proliferative responses of Mycobacterium bovis-infected cattle to purified protein derivative AN - 17743389; 4806329 AB - Despite highly successful eradication efforts in several countries, Mycobacterium bovis infection of cattle remains a significant health concern worldwide. Immune mechanisms of resistance to and/or clearance of M. bovis infection of cattle, however, are unclear. Recent studies have provided evidence supporting a role for CD4 super(+), CD8 super(+), and gamma delta TCR super(+) T cells in the response of cattle to M. bovis. In the present study, we utilized a flow cytometric-based proliferation assay to determine the relative contribution of individual lymphocyte subsets in the response to M. bovis infection and/or sensitization with mycobacterial purified protein derivative (PPD). Peripheral blood mononuclear cells (PBMC) from M. bovis-infected cattle proliferated in response to in vitro stimulation with M. bovis PPD. CD4 super(+) T cells and gamma delta TCR super(+) cells were the predominate subsets of lymphocytes responding to PPD. gamma delta TCR super(+) cells also proliferated in non-stimulated cultures; however, the gamma delta TCR super(+) cell proliferative response of infected cattle was significantly ( p<0.05 ) greater in PPD-stimulated cultures as compared to non-stimulated cultures. Intradermal injection of PPD for comparative cervical testing (CCT) induced a boost in the in vitro proliferative response of CD4 super(+) but not gamma delta TCR super(+) cells of infected cattle. Administration of PPD for CCT also boosted interferon- gamma (IFN- gamma ) production by PBMC of infected cattle following in vitro stimulation with M. bovis PPD. Injection of PPD for CCT did not, however, elicit a proliferative or IFN- gamma response in cells isolated from non-infected cattle. These data indicate that CD4 super(+) and gamma delta TCR super(+) cells of M. bovis-infected cattle proliferate in a recall response to M. bovis PPD and that the CD4 super(+) cell response is boosted by intradermal injection with PPD for CCT.

Cell-mediated immune responses modulated by various T cell subsets are essential to provide protective immunity and prevent progression of the disease. Secretion of cytokines by T cell populations serves to activate macrophages to kill ingested M. paratuberculosis as well as activate other T cell subsets to contain the infection. This paper reviews the current knowledge of T cell immune responses in M. paratuberculosis infection based upon clinical studies and research using mouse models.

However, the hydrolytic activity of OPH against the warfare agent VX is less than 0.1% relative to its activity against parathion and paraoxon. Based on the crystal structure of OPH and the similarities it shares with acetylcholinesterase, eight OPH mutants were constructed with the goal of increasing OPH activity toward VX. The activities of crude extracts from these mutants were measured using VX, demeton-S methyl, diisopropylfluoro-phosphate, ethyl parathion, paraoxon, and EPN as substrates. One mutant (L136Y) displayed a 33% increase in the relative VX hydrolysis rate compared to wild type enzyme. The other seven mutations resulted in 55-76% decreases in the relative rates of VX hydrolysis. There was no apparent relationship between the hydrolysis rates of VX and the rates of the other organophosphorus compounds tested.

AN - 72512036; 11192175 AB - Earlier surveys indicate that meat, fish and dairy products are the principal source of polychlorinated dibenzo-p-dioxin (PCDD) exposure in the diet. A recent finding by others of PCDDs in chickens that consumed a feed containing PCDD led to the finding of ball clay, an anti-caking agent, as the source. Supercritical fluid extraction (SFE) was studied as a means to isolate PCDDs from commercial ball clays using GC-electron capture detection (muECD) as a means to screen for these contaminants. The finding of ng/g amounts and recoveries >100% in several samples of ball clay containing octachlorodibenzo-p-dioxin (OCDD) suggested that PCDD may form artifactually as a result of analysis. Studies on pentachlorophenol (PCP) fortified ball clay were carried out by SFE and soxhlet extraction and the results compared. The values obtained by SFE were considered more problematic.

(Insecta, Lepidoptera, Tortricidae). AN - 72574514; 11223936 AB - Larvae of the navel orangeworm (NOW), Amyelois transitella (Walker), a major pest of almonds and pistachios, and the codling moth (CM), Cydia pomonella (L.), the principal pest of walnuts and pome fruits, are commonly found in tree nut kernels that can be contaminated with aflatoxin, a potent carcinogen. The ability of larvae of these insects to metabolize aflatoxin B1 (AFB1) was examined. A field strain of NOW produced three AFB1 biotransformation products, chiefly aflatoxicol (AFL), and minor amounts of aflatoxin B2a (AFB2a) and aflatoxin M1 (AFM1). With AFL as a substrate, NOW larvae produced AFB1 and aflatoxicol M1 (AFLM1). A lab strain of CM larvae produced no detectable levels of AFB1 biotransformation products in comparison to a field strain which produced trace amounts of only AFL. Neither NOW nor CM produced AFB1-8,9-epoxide (AFBO), the principal carcinogenic metabolite of AFB1. In comparison, metabolism of AFB1 by chicken liver yielded mainly AFL, whereas mouse liver produced mostly AFM1 at a rate eightfold greater than AFL. Mouse liver also produced AFBO. The relatively high production of AFL by NOW compared to CM may reflect an adaptation to detoxify AFB1. NOW larvae frequently inhabit environments highly contaminated with fungi and, hence, aflatoxin. Only low amounts, if any, of this mycotoxin occur in the chief CM hosts, walnuts, and pome fruits. Characterizations of enzymes and co-factors involved in biotransformation of AFB1 are discussed.

AN - 72568719; 11171279 AB - Fatty acids esters were produced from two Nigerian lauric oils, palm kernel oil and coconut oil, by transesterification of the oils with different alcohols using PS30 lipase as a catalyst. In the conversion of palm kernel oil to alkyl esters (biodiesel), ethanol gave the highest conversion of 72%, t-butanol 62%, 1-butanol 42%, n-propanol 42% and iso-propanol 24%, while only 15% methyl ester was observed with methanol. With coconut oil, 1-butanol and iso-butanol achieved 40% conversion, 1-propanol 16% and ethanol 35%, while only traces of methyl esters were observed using methanol. Studies on some fuel properties of palm kernel oil and its biodiesel showed that palm kernel oil had a viscosity of 32.40 mm2/s, a cloud point of 28 degrees C and a pour point of 22 degrees C, while its biodiesel fuel had a viscosity of 9.33 mm2/s, a cloud point of 12 degrees C and a pour point of 8 degrees C. Coconut oil had a viscosity of 28.58 mm(2)/s, a cloud point of 27 degrees C and a pour point of 20 degrees C, while its biodiesel fuel had a viscosity of 7.34 mm2/s, a cloud point of 5 degrees C and a pour point of -8 degrees C. Some of the fuel properties compared favourably with international biodiesel specifications.

AN - 72566999; 11171219 AB - Phospholipase D (PLD) initiates phospholipid (PL) catabolism in plant cells and is also involved in signal transduction and retailoring of membrane PL. Total PL declines and phosphatidic acid increases in pericarp tissue during tomato fruit ripening, suggesting that increased PLD activity alters membrane structure. To assess the role of PLD in tomato ripening, we have begun a molecular genetic approach. Using a castor bean PLDalpha cDNA as a probe, a PLDalpha cDNA (LEPLD2) was isolated from our tomato fruit library. It has an open reading frame of 2421 nucleotides, encoding a polypeptide of 807 amino acids with a molecular mass of 92 kDa. The deduced LEPLD2 PLDalpha shares >75% sequence identity with PLDalphas from castor bean, tobacco and tomato. LEPLD2 transcript, detected by RNA gel-blot analysis, was very low in roots, low in stems, moderate in leaves, high in flowers, and increased in fruit during development and ripening. Expression of LEPLD2 in Escherichia coli yielded active enzyme, and a FLAG-PLDalpha fusion protein produced by transformed E. coli migrated close to the calculated 94 kDa on SDS/PAGE.

AN - 72522613; 11142322 AB - Studies were undertaken to determine whether irradiation treatment at 250 Gy, an accepted treatment for disinfestation of fruit flies in spindaceous fruits from Hawaii, would also disinfest fruit of two species of Cryptophlebia. Cryptophlebia illepida (Butler) was determined to be more tolerant of irradiation than Cryptophlebia ombrodelta (Lower); therefore, C. illepida was the focus for detailed tests. Using the criterion of success in developing to the adult stage, the pattern of tolerance to irradiation in C. illepida was generally eggs or = 125 Gy. No C. illepida larvae receiving an irradiation dose > or = 125 Gy emerged as adults and produced viable eggs, indicating sterility can be achieved at doses well below 250 Gy. In large scale tests, when 11,256 late instars were irradiated with a target dose of 250 Gy, 951 pupated (8.4%) and none eclosed as adults. Within the pupal stage, tolerance increased with age; 7- to 8-d-old pupae (the oldest pupae tested) treated with an irradiation dose of 125 Gy produced viable offspring, whereas those treated with a dose of 250 Gy produced no viable offspring. Irradiation of adults with a target dose of 250 Gy before pairing and mating resulted in no viable eggs. Irradiation of actively ovipositing adult females resulted in no subsequent viable eggs. Therefore, the irradiation quarantine treatment of a minimum absorbed dose of 250 Gy approved for Hawaii's fruits will effectively disinfest fruits of any Cryptophlebia in addition to fruit flies.

AN - 72518917; 11142293 AB - We evaluated the toxicity of three insecticides (lambda cyhalothrin, spinosad, and S-1812) to the natural enemies Bracon mellitor Say, Cardiochiles nigriceps Viereck, Coleomegilla maculata De Geer, Cotesia marginiventris (Cresson), Geocoris punctipes (Say), and Hippodamia convergens Guérin-Méneville, in topical, residual, and field assays. Lambda cyhalothrin exhibited the greatest toxicity to the natural enemies. In topical toxicity tests, lambda cyhalothrin adversely affected each natural enemy species studied. Residues of lambda cyhalothrin on cotton leaves were toxic to B. mellitor, C. nigriceps, C. maculata, and C. punctipes. Interestingly, residues of this insecticide were not very toxic to C. marginiventris and H. convergens. Geocoris punctipes and C. maculata numbers in the field generally were significantly lower for lambda cyhalothrin treatments than for the other four treatments, substantiating the previous tests. Although cotton aphids began to increase over all treatments around the middle of the test period, the number of cotton aphids in the lambda cyhalothrin plots was significantly higher than the number in any of the other treatments. As cotton aphids increased in lambda cyhalothrin field plots, the predator H. convergens also increased in number, indicating that lambda cyhalothrin did not adversely affect it in accordance with the residual tests. Spinosad exhibited marginal to excellent selectivity, but was highly toxic to each parasitoid species and G. punctipes in topical toxicity tests and to B. mellitor in residual tests. Spinosad generally did not affect the number of G. punctipes, H. convergens, and C. maculata in the field except for one day after the second application for G. punctipes. S-1812 exhibited good to excellent selectivity to the natural enemies. Some reduction of G. punctipes occurred for only a short period after the first and second application of this insecticide in the field. H. convergens and C. maculata were affected very little by S-1812.

AN - 72518703; 11142297 AB - In 1995, ears of a experimental inbred (CG59-2) containing a synthetic Bacillus thuringiensis Cry IA (b) gene driven by PEPC, pith and pollen promoters and artificially infested with Ostrinia nubilalis (Hübner) larvae in small plot studies were free from insect damage, whereas 40-50% of the corresponding non-Bt inbred ears were damaged. Bt inbred ears that were inoculated with Aspergillus flavus Link and Fusarium proliferatum T. Matsushima (Nirenberg) or exposed to natural mold inoculum after infestation with O. nubilalis were free of visible signs of mold, as compared with approximately 30-40% of the non-Bt ears similarly treated. Results in 1996 using the same inbred with a single allele dose of the Bt gene showed similar trends. Mean total fumonisin levels for non-Bt versus Bt inbred ears were not significantly different (2.8 versus 0.8 ppm, respectively) in 1996. In paired hybrid studies run in 0.4-ha (1-acre) fields, an event 176 Bt hybrid had significantly lower amounts of damage and signs of Fusarium spp. mold, but not fumonisin, compared with a corresponding non-Bt hybrid from 1996 to 1998. However, two hybrid pairs that contained either MON810 or Bt11 constructs examined in similar fields at the same site had lower levels of fumonisin in both 1997 (30- to 40-fold) and 1998. High intrafield variability in insect infestation and presence of Helicoverpa zea (Boddie) in Bt hybrids was apparently responsible for fewer significant differences in fumonisin levels in 1998. Similar trends for all three hybrid pairs were noted in small plot trials at another site. Incidence of other ear pests or insect predators varied as much among non-Bt hybrids as they did for Bt/non-Bt hybrid pairs.

AN - 72486813; 11123549 AB - We have developed an efficient process for rapidly isolating campylobacter DNA using mechanical disruption combined with the guanidine-based reagent DNAzol. Template DNA was isolated by this method from cultures of Campylobacter jejuni resistant to lysis by boiling or enzymes and identified following polymerase chain reaction (PCR) amplification using primers specific for the hippuricase gene. Direct detection of campylobacters in poultry-processing samples by PCR is demonstrated in chicken carcass rinses spiked with lysis-resistant C. jejuni. Our results indicate that this method of DNA isolation may be ideal for direct PCR detection of pathogenic bacteria in complex samples of widely varied origin, especially when the target organisms are difficult to lyse by other means.

AN - 72432686; 11097924 AB - We have developed two sets of Campylobacter shuttle vectors containing either the gfp (green fluorescent protein), yfp (yellow fluorescent protein), or cfp (cyan fluorescent protein) reporter gene. In one set, the reporter gene is fused to a consensus Campylobacter promoter sequence (P(c)). The other set contains a pUC18 multicloning site upstream of the reporter gene, allowing the construction of transcriptional fusions using known promoters or random genomic fragments. C. jejuni cells transformed with the P(c) fusion plasmids are strongly fluorescent and easily visualized on chicken skin, on plant tissue, and within infected Caco-2 cells. In each C. jejuni strain tested, these plasmids were maintained over several passages in the absence of antibiotic selection. Also, in many C. jejuni strains, >91% of the cells transformed with the P(c) fusion plasmids remained fluorescent after several days. Experiments with yellow fluorescent and cyan fluorescent C. jejuni transformants suggest that aggregates containing two or more strains of C. jejuni may be present in an enrichment broth culture. Colonies arising from these aggregates would be heterologous in nature; therefore, isolation of a pure culture of C. jejuni, by selecting single colonies, from an environmental sample may not always yield a single strain.

Evidence from Time Diary Data, 1965 to 1993 AN - 60448429; 200200399 AB - Now that married women are working more for pay than they were three decades ago, are they less likely to volunteer? I use national time diary surveys conducted in 1965, 1975, 1985, & 1993 to document a decrease in the weekly volunteer participation rate of working-age married women, from 16.4% in 1965 to 9.3% in 1993. Changes in observable characteristics explain about 65% of the decrease in married women's volunteer participation from 1965 to 1985. The increased employment rates of married women as well as the changes in their parental status are substantial contributors to the decline in their volunteer participation. Married women's gain in educational attainment is the most important factor in the decline in their volunteer participation. However, married women's changing labor force & parental status do not explain why married women's volunteer participation continued to decline from 1985 to 1993. 7 Tables, 4 Figures, 3 Appendixes, 26 References.

The heavy silt fraction (2-63 mu m, density >2.95) isolated from the sediments was analyzed for 42 elements by inductively coupled plasma-mass spectrophotometry (ICP-MS) to give signature profiles characteristic of each source catchment. Known proportions of heavy silt fractions from each source were mixed and the composite samples analyzed in the same way. The proportions of components in the composite samples were compared to their apportionments calculated statistically using the US Environmental Protection Agency (USEPA) chemical mass balance (CMB) air quality receptor model. This showed that the CMB technique can apportion sediments to their catchment sources reliably. The technique was then applied to dated sediments of Lake Pepin, in the Upper Mississippi basin, to apportion them to their contributing catchments. The results show that almost all the recent sediments deposited in the basin originated in the Minnesota River catchment, and that the sediment load increased over time as anthropogenic impacts increased.

As a redox-sensitive element, the fate and toxicity of chromium is controlled by soil reduction-oxidation (redox) reactions. In-situ remediation of chromium combines reduction of Cr(VI) to Cr(III) and immobilization of chromium on mineral surfaces. In this study, Fe-rich smectite, montmorillonite, illite, vermiculite, and kaolinite were examined to determine reactivity in sorption-reduction of Cr(VI). The clays were compared to forms that were reduced by sodium dithionite. Clays containing Fe(II) efficiently removed soluble Cr(VI) from solution. Chromium K-edge X-ray absorption near edge structure (XANES) suggested that clays containing Fe(II) reduced Cr(VI) to Cr(III), immobilizing Cr at the clay/water interface. Adsorption of Cr(VI) by the Fe(II)-containing clay was a prerequisite for the coupled sorption-reduction reaction. Sodium dithionite added directly to aqueous suspensions of non-reduced clays reduced Cr(VI) to Cr(III), but did not immobilize Cr on clay surfaces. The capacity of clays to reduce Cr(VI) is correlated with the ferrous iron content of the clays. For dithionite-reduced smectite, the exchangeable cation influenced the sorption reaction, and thus it also influenced the coupled sorption-reduction reaction of Cr(VI). The pH of the aqueous system affected both the amount of Cr(VI) reduced to Cr(III) and the partition of Cr(III) between aqueous and adsorbed species. A plot of pH vs. amount (adsorption envelope) adsorbed for the coupled sorption-reduction reaction of Cr by reduced smectite exhibited a similar pattern to that of typical anion-sorption.

These depreciative activities also reduce the quality of visitors' experiences in the damaged areas. Indirect methods, such as visitor education through brochures and signs, continue to be the least controversial management approaches to depreciative acts. Yet, the literature on studies examining the most effective message presentations remains sparse. A survey mailed to randomly selected National Association for Interpretation members assessed the perceived effectiveness of communications that encouraged positive conduct (proscriptive messages) versus those that discouraged negative conduct (proscriptive messages) in wildland and urban settings. Almost invariably, respondents viewed the encouragement-based prescriptive messages as more effective than the discouragement-based proscriptive messages. This finding stands in sharp contrast to an earlier study that discovered a preponderance of proscriptive versus prescriptive messages on signs in both wildland and urban recreational environments. Thus, although the great majority of interpreters see the encouragement of positive conduct as more effective, in practice, messages on signs are much more likely to discourage negative conduct. Reasons for this discrepancy are considered.

Weeds of a given species were sown at a density of two per metre of row. A significant reduction in soybean seed yield was observed with either weed species relative to the weed-free control at either [CO sub(2)]. However, for lambsquarters the reduction in soybean seed yield relative to the weed-free condition increased from 28 to 39% as CO sub(2) increased, with a 65% increase in the average dry weight of lambsquarters at enhanced [CO sub(2)]. Conversely, for pigweed, soybean seed yield losses diminished with increasing [CO sub(2)] from 45 to 30%, with no change in the average dry weight of pigweed. In a weed-free environment, elevated [CO sub(2)] resulted in a significant increase in vegetative dry weight and seed yield at maturity for soybean (33 and 24%, respectively) compared to the ambient CO sub(2) condition. Interestingly, the presence of either weed negated the ability of soybean to respond either vegetatively or reproductively to enhanced [CO sub(2)]. Results from this experiment suggest: (i) that rising [CO sub(2)] could alter current yield losses associated with competition from weeds; and (ii) that weed control will be crucial in realizing any potential increase in economic yield of agronomic crops such as soybean as atmospheric [CO sub(2)] increases.

The aim of this work was to determine if changes in apple physiology caused by the proliferation of fungal decay organisms would foster the survival of E. coli O157:H7. Trials were performed where (A) plant pathogens (4 log sub(10) spores) were added to apple wounds 4 days before the wounds were inoculated with E. coli O157:H7 (3 log sub(10) CFU g super(-1) apple) (both RT and 4 degree C storage), (B) plant pathogens and E. coli O157:H7 were added on the same day (both RT and 4 degree C storage), and (C) E. coli O157:H7 was added 2 days (RT storage) and 4 days (4 degree C storage) before plant pathogens. In all trials E. coli O157:H7 levels generally declined to <1 log sub(10) at 4 degree C storage, and in the presence of P. expansum at 4 degree C or RT. However, in the presence of G. cingulata at RT E. coli O157:H7 numbers increased from 3.18 to 4.03 log sub(10) CFU g super(-1) in the apple wound during trial A, from 3.26 to 6.31 log sub(10) CFU g super(-1) during trial B, and from 3.22 to 6.81 log sub(10) CFU g super(-1) during trial C. This effect is probably a consequence of the attendant rise in pH from 4.1 to approximately 6.8, observed with the proliferation of G. cingulata rot. Control apples (inoculated with E. coli O157:H7 only) were contaminated with opportunistic decay organisms at RT during trials A and B, leading to E. coli O157:H7 death. However, E. coli O157:H7 in control apples in trial C, where no contamination occurred, increased from 3.22 to 5.97 log sub(10) CFU g super(-1). The fact that E. coli O157:H7 can proliferate in areas of decay and/or injury on fruit highlights the hazards associated with the use of such fruit in the production of unpasteurized juice.

Within this study, the prevalence of Salmonella spp. shed in feces was determined. A total of 5,049 fecal samples were collected from 187 beef cow-calf operations each visited on a single occasion. The number of fecal samples collected per operation was predetermined based on herd size. Salmonellae were recovered from 1 or more fecal samples collected on 11.2% (21 of 187) of the operations. Overall 78 salmonellae representing 22 serotypes were recovered from 1.4% (70 of 5,049) of samples. Multiple serotypes were recovered from eight samples from a single operation. The five most common serotypes were Salmonella Oranienburg (21.8% of isolates), and Salmonella Cerro (21.8%), followed by Salmonella Anatum (10.3%), Salmonella Bredeney (9.0%), and Salmonella Mbandaka (5.1%). The most common serogroups identified were C sub(1) (33.3%), K (21.8%), B (16.7%), and E (15.4%). Even though the recovery rate of salmonellae from fecal samples was very low, 43.6% (34 of 78) and 38.5% (30 of 78) of the isolates were among the 10 most common serotypes from cattle with clinical signs of disease or isolated from humans, respectively. The majority of the isolates (50 of 78; 64.1%) were recovered from fecal samples from two operations. All isolates were screened for resistance to a panel of 17 antimicrobics, and 87.2% (68 of 78) were susceptible to all of the antimicrobics. The resistant isolates were most commonly resistant to streptomycin (n = 9) and/or sulfamethoxazole (n = 9). Nine isolates showed multiple ( greater than or equal to 2 antimicrobics) resistance most commonly to streptomycin and sulfamethoxazole (n = 6).

Ground turkey was gamma irradiated at 5 degree C to 0, 1.5, and 2.5 kGy and inoculated ( similar to 100 CFU/g) after irradiation with a cocktail of L. monocytogenes ATCC 7644, 15313, 49594, and 43256. The meat was then packaged in air-permeable pouches or under atmospheres containing 30 or 53% CO sub(2), 19% O sub(2), and 51 or 24% N sub(2) and stored at 7 degree C for up to 28 days. A dose of 2.5 kGy extended the time for the total plate count (TPC) to reach 10 super(7) CFU/g from 4 to 19 days compared to that for nonirradiated turkey in air-permeable pouches. Following a dose of 2.5 kGy at the end of the 28-day study, the TPCs were 10 super(6.42) and 10 super(4.98) under 25% and 50% CO sub(2) atmospheres, respectively. Under air, 30% CO sub(2), and 53% CO sub(2) atmospheres, the populations of L. monocytogenes after 19 days incubation were 10 super(4.89), 10 super(3.60), and 10 super(2.67) CFU/g.

These isolates had previously been categorized into 19 PvuII ribotypes. Twenty restriction endonucleases were evaluated for use in REA. Digestion of chromosomal DNA with HinfI, followed by submarine electrophoresis in agarose gels and staining with ethidium bromide, produced DNA fragments in the 4.0- to 10-kb range, which readily discriminated B. bronchiseptica isolates, resulting in 48 fingerprint patterns. Moreover, AluI digestion of chromosomal DNA produced 39 distinct fingerprint profiles with DNA fragments ranging from 6.0 to 20.0 kb. While REA frequently provided more discriminatory power than ribotyping, there were examples where the use of ribotyping was more discriminatory than REA. Passage of selected isolates up to passage 25 did not change the REA profile. Moreover, the Bvg phase did not alter the fingerprint profile of chromosomal DNA from B. bronchiseptica strains digested with HinfI or AluI. Based on the results presented herein, the combination of REA and ribotyping should provide valuable information in understanding the molecular epidemiology of Bbronchiseptica infections.

Merr.] has been shown to be very sensitive to drying soil. Since this loss of N sub(2) fixation activity has a negative impact on crop yield under many cropping situations, alleviation of this response would be a major benefit. The objective of this research was to screen a large number of plant introduction lines in an effort to identify soybean germplasm that might have substantially decreased sensitivity of N sub(2) fixation to water deficits. A three-stage screening process was developed to narrow successively the number of candidate lines for tolerance in this trait. The first-stage screen involved the measurement of petiole ureide levels in a large number of plant introductions (approx. 1000 per year). Approximately 10% of the lines with low petiole ureide levels, which are generally associated with N sub(2) fixation tolerance, were selected. The second-stage screen involved subjecting field plots of each selected plant introduction to a sustained water deficit of approximately 3 wk and measuring N accumulation during this period. Again, about 10% of these lines were selected for the intensive third-stage screen based directly on an acetylene reduction assay during a cycle of soil drying. From an initial population of about 3000 plant introduction lines, eight lines were identified as having substantial tolerance of N sub(2) fixation to soil drying. These eight lines are to be used in physiological studies to investigate the basis of their tolerance, and in breeding efforts to incorporate this trait into commercial germplasm.

Primary cultures of teleost brain cells and cytotoxicity assays have not been previously employed to assess toxicity of these agents. Primary cultures of brain cells from tilapia and the following colorimetric assays, 5-(3-carboxylmethoxy-phenyl)-2-(4,5-dimethylthiazoyl)-3-(4-sulfoph enyl) tetrazolium, inner salt (MTS), 3-(4,5-dimethylthiazol-2-yl)-2,5-(diphenyltetrazolium bromide (MTT), lactate dehydrogenase (LHD), bromodeoxyuridine and neutral red (NR), were used to measure cytotoxicity and compared to results from other teleost primary cultures of brain cells and established cell lines. The results showed that primary brain cells were more sensitive than cell lines in predicting aquatic neurotoxicity. Significant positive correlations between MTS and MTT and between these tetrazolium-based assays and LDH were found. The NR assay was the least sensitive and was not positively correlated to the other assays.

The neurotoxic potential of benzothiazole was investigated following in vivo and in vitro exposure of sheepshead minnows to 3.75, 7.5, 15, 30 and 60 mg/l benzothiazole. Following benzothiazole exposure, fish were evaluated for survival, growth and histological alterations. Fish mortality occurred after 5 days of exposure to 60 mg/l (LC sub(50) = 41.9). Significant decreases in larval growth were noted at all concentrations. Histologically, gills had cellular alterations but the central nervous system lacked the severe cellular damage seen in previous tire leachate exposure studies. Benzothiazole cytotoxicity to primary cultures of brain cells from sheepshead minnow and tilapia (Oreochromis niloticus) and two epithelial cell lines was evaluated using a tetrazolium salt assay (MTT) at 1 and 4 days. In vitro results indicate primary cultures of brain cells are less sensitive to benzothiazole than epithelial cell lines. Significant cytotoxicity to the epithelial cell lines was noted at 30 and 60 mg/l concentrations. Histologically and cytotoxicologically, the present study indicates that benzothiazole is a gill toxicant and not a neurotoxicant.

The measure of damages in the statutes is the cost of restoring the resources to baseline conditions, plus the interim loss in value from the time of the incident until full recovery of the resources. The statutory restriction limiting use of the monies to enhancing or creating natural resources motivated the development of an alternative measure for interim losses - the cost of compensatory restoration actions providing in-kind compensation. In this paper alternative measures of damages are outlined and approaches and methods for scaling compensatory restoration are discussed. Two basic scaling approaches are presented: a simplified in-kind trading procedure and the more general valuation approach, in which a variety of economic methods may be employed to assess the trade-offs between gains from proposed actions and interim losses from the injuries. Experience indicates that natural resource liability actions represent a potent tool for federal and state resource managers to address injuries to public resources.

To simulate these impacts, long-term daily rainfall data are necessary. In the absence of measured rainfall data, watershed models use weather generators to simulate rainfall events. The objective of this study is to examine several daily precipitation generators in terms of the hydrologic response of SWAT. SWAT is generally applied to large river basins but has been validated and applied on the small watershed scale as well. Daily rainfall inputs included a 60-year measured rainfall record from 1939 to 1998 for Riesel, Texas, in the heart of the Blackland Prairie, and data generated with the precipitation components of three weather generation programs: WGEN, WXGEN, and USCLIMATE. Measured and generated rainfall were input into SWAT and run for a 53 ha watershed near Riesel, Texas. Rainfall totals, extreme rainfall events, and the resulting hydrologic responses of runoff volume and peak flows were then examined. For this study scenario, WXGEN was able to more closely match observed rainfall than WGEN and USCLIMATE. In terms of resulting SWAT hydrologic response, WXGEN rainfall best reproduced runoff volumes simulated with measured rainfall, and USCLIMATE performed better in reproducing peak runoff rates. These are important results as probabilities of exceeding runoff volume or peak flow thresholds are often questions of interest in watershed projects.

While it is generally accepted that the improved soil properties associated with manure application lead to changes in runoff and soil erosion, few studies have quantified these impacts. Water quality models used to assess watershed management and estimate total maximum daily load must accurately predict loading rates from fields where manure has been applied. This study was conducted to assemble and summarize information quantifying the effects of manure application on runoff and soil loss resulting from natural precipitation events, and to develop regression equations relating runoff and soil loss to annual manure application rates. For selected locations at which manure was added annually, runoff was reduced from 2 to 62%, and soil loss decreased from 15 to 65% compared to non-manured sites. Measured runoff and soil loss values were reduced substantially as manure application rates increased. Regression equations were developed relating runoff and soil loss to manure application for rates ranging from 11 to 45 Mg ha super(-1), and slope lengths varying from 21 to 24 m. The equations can be used in estimating environmental impacts or to account for manure applications in water quality modeling efforts.

Runoff from small natural-precipitation infiltrometer plots (0.25 m super(2)) under natural conditions can be merely drip flows, or they can be larger flows when runoff is produced simultaneously from high-intensity rains and seepage. A study of a drip-flow/low-flow nozzle/rotor flow-measuring system that met design requirements for runoff measurement is presented. Comparison of different nozzle configurations led to the selection of the rotor of a Price current meter, in combination with a unique nozzle that incorporated a drip diverter, an internal flow baffle, and drip-control silicone beads. The best nozzle/rotor combination yielded a rating curve with a resolution less than design requirements, and worked well with flows as high as similar to 6 L min super(-1), greater than design requirements. A combined function using linear segments for low flows, and a 4th degree polynomial for high flows, comprised the rating curve. The average residual error about the function was 0.113 L min super(-1). Unsteady flow tests with the nozzle showed that the rating curve and nozzle/rotor assembly worked well, with the median error in volume of -21 mL for 12 synthesized "events". The device is a standalone measuring system that can be placed anywhere on the landscape, and only electrical pulses, representing rotor-rotation speed require measurement. The nozzle/rotor system can be used for other applications in which drip and low flows need to be measured, such as for rain gauges, percolation flows from lysimeters, spring flows, etc. JF - Transactions of the ASAE AU - Bonta, J V AU - Goyal, V C AD - USDA-ARS, PO Box 488, Coshocton, OH 43812, USA, bonta@coshocton.com Y1 - 2000/12// PY - 2000 DA - Dec 2000 SP - 1489 EP - 1498 VL - 43 IS - 6 SN - 0001-2351, 0001-2351 KW - Water Resources Abstracts KW - Percolation KW - Measuring Instruments KW - Infiltrometers KW - Rain Gages KW - Infiltration KW - Lysimeters KW - Runoff KW - SW 5040:Data acquisition UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/17897472?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%3Awaterresources&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Transactions+of+the+ASAE&rft.atitle=Comparison+of+drip-flow%2Flow-flow+measuring+devices+for+infiltrometer+runoff+measurements&rft.au=Bonta%2C+J+V%3BGoyal%2C+V+C&rft.aulast=Bonta&rft.aufirst=J&rft.date=2000-12-01&rft.volume=43&rft.issue=6&rft.spage=1489&rft.isbn=&rft.btitle=&rft.title=Transactions+of+the+ASAE&rft.issn=00012351&rft_id=info:doi/ LA - English DB - ProQuest Environmental Science Collection N1 - Last updated - 2015-03-24 N1 - SubjectsTermNotLitGenreText - Percolation; Infiltrometers; Measuring Instruments; Rain Gages; Infiltration; Lysimeters; Runoff ER - TY - JOUR T1 - Estimating Manning's roughness coefficient for shallow overland flow in non-submerged vegetative filter strips AN - 17897437; 5137967 AB - Results of an experimental study showed that overland flow in non-submerged vegetative filter strips can be described by the Petryk and Bosmajian's modified Manning's formula with a variable roughness coefficient. The roughness coefficient is made up of the shear stress caused by the boundary roughness and the drag force caused by the vegetative elements. The resistance due to vegetation was related to vegetation density and flow depth. For small flow rates, the shear stress at the boundary played the major role. As the flow rate increased, the drag force due to the vegetative elements became dominant. The model can be used to estimate flow velocity in vegetative filter strips (VFS).

A factorial pot experiment was conducted with two muck soils contaminated by a Ni refinery; we tested the effectiveness of making the soil calcareous and addition of freshly precipitated hydous ferric oxide (HFO) in reducing soil Ni phytotoxicity to the Ni-sensitive crops, oat and redbeet, and a Ni-resistant crop, wheat. Fertilized but otherwise untreated soil caused significant Ni phytotoxicity to oats and redbeet, but not to wheat, on both soils. Adding limestone reduced the concentration of Ni in shoots of all species and alleviated the symptoms specific to Ni phytotoxicity in oat (banded chlorosis). The addition of HFO was more effective in reducing shoot Ni concentration in the redbeets than in crops from the Poaceae family. Both amendments induced phosphorus and/or manganese deficiency depending on the crop tested. The experiment indicates that some combination of limestone and Fe oxides can readily remediate Ni phytotoxicity of the tested soils, but that Mn and P fertilizers would be needed to achieve practical in situ remediation of Ni phytotoxicity of Quarry muck (Terric Mesisol).

We evaluated different strategies for adding PAM to irrigation water to determine which was most effective. The PAM was applied to irrigation water in gated irrigation pipe as dry granules, or to furrow inflows as a stock solution. Treatment efficacy varied primarily with irrigation inflow-rate, PAM concentration in irrigation water, duration of furrow exposure, and total PAM applied. The most effective erosion-control treatments either (1) applied an initial dose of PAM at 10 mg L super(-1) in irrigation inflows only during the furrow advance period; (2) applied an initial 5 mg L super(-1) dose, then reapplied PAM for 5 to 15 min episodically at similar concentrations; or (3) continually applied 1 to 2 mg L super(-1) to irrigation inflows. The full-advance treatment reduced sediment loss by 93%, compared to 60% for the continuous 0.25 mg L super(-1) PAM application when slopes were 1 to 2%. Dry and solution applications controlled erosion about equally. The PAM applications were economical and effective methods for controlling furrow-irrigation induced erosion, under a broad range of field conditions.

AN - 17887697; 5127216 AB - Viviparity and placentation have evolved many times within squamate reptiles, but the sequence in which the attendant morphological modifications occur remains unclear. In particular, it is unknown whether a reduction of the egg shell occurs concurrently with longer periods of egg retention (i.e. increasingly advanced stages of embryogenesis at oviposition) or whether such thinning occurs after viviparity has evolved. To investigate this question, we evaluated the prediction that shell morphology and permeability vary systematically with the capacity to support embryonic development in utero (as judged by the maximum embryonic stage attainable in utero) in five species of oviparous sceloporine lizards and one lizard species in the sister genus Urosaurus. Despite major differences among species in the capacity to support embryogenesis, shell morphology (structure, thickness) and physiology (permeability to water vapour) did not vary as predicted. These results raise the intriguing possibility that other features associated with simple placentation (e.g. increased oviductal and chorioallantoic vascular density) evolve concurrently with longer periods of egg retention and viviparity and that shell thinning may occur subsequent to the evolution of viviparity, at least in sceloporine lizards.

The intensity of infection varied among three sites on the Comal River. In contrast, of 130 darters from the nearby San Marcos River that were examined, only 4 (3%) were infected, and these had 1-2 cysts per fish. Of 2,279 Melanoides tuberculata snails from the Comal River that were examined, 139 (6.1%) were infected with the trematode. Only 1 snail in 2,241 from the San Marcos River that were examined was infected. The presence of metacercariae in darters was associated with flared opercula, shortened or thickened gill filaments, epithelial hyperplasia, and engorged lamellae. The normal cartilage support of the filaments was distorted and displaced, leading to severe deformities of filament structure. Gill damage was severe and possibly life threatening for the darters with more than 800 cysts per fish (9% of examined fish). We suspect that fountain darter deaths were caused by the parasite in the Comal River during this study.

After passage of these bacterial isolates in an aerobic environment, minimal growth was observed. In thioglycolate broth, the passaged isolates had growth characteristics of bacteria with a limited tolerance for oxygen. Isolate S97-133, from May 1997, was identified as E. ictaluri by the National Veterinary Services Laboratories, Diagnostic Bacteriology Laboratory, Ames, Iowa. The S97-133 isolate and three others from 1994 were also definitively identified as E. ictaluri by the use of the monoclonal immuno dot-blot technique. In all, eight isolates were obtained from channel catfish over an 8-year period. All isolates were obtained during the months of May, June, July, and November.

Beetle - host tree combinations included Conophthorus ponderosae Hopkins on Pinus ponderosa Laws., C. ponderosae on Pinus monticola Dougl., Conophthorus conicolens Wood on Pinus pseudostrobus Lindl., Conophthorus teocotum Wood on Pinus teocote Schl. & Cham., Conophthorus coniperda (Schwarz) on Pinus strobus L., and Conophthorus resinosae Hopkins on Pinus resinosa Ait. trans-Verbenol was tested only on C. resinosae on P. resinosa. Traps baited with pityol caught more beetles than unbaited traps in nearly all of the assays, and conophthorin consistently inhibited male beetle response to pityol for all species tested. Behavioral responses of species of Conophthorus to alpha -pinene appeared to parallel host phylogeny, inasmuch as beetles using Haploxylon pines as hosts utilized alpha -pinene as a synergist for the beetle-produced pityol, whereas beetles using Diploxylon pines as hosts did not. alpha -Pinene was a synergist for pityol in C. ponderosae on P. monticola and C. coniperda on P. strobus, but not for species of Conophthorus on any other pines tested. Conophthorus ponderosae on P. ponderosa was the only beetle-host combination tested where verbenone was a synergist for pityol, but this effect was not consistent in all years of testing. It was also the only beetle-host combination in which 4-allylanisole was a repellent. For all other beetle-host combinations, verbenone was neutral to slightly repellent and 4-allylanisole was either synergistic or neutral in pityol-baited traps. Promising synergists and interruptants/repellents were identified for implementation in pest-management regimes, including conophthorin as an interruptant for all species of Conophthorus tested, 4-allylanisole as an interruptant for C. ponderosae on P. ponderosa, alpha -pinene as a synergist for pityol in all species tested on Haploxylon pines, and 4-allylanisole as a synergist for pityol in C. conicolens and C. coniperda..

One question that needs to be examined is whether the adverse outcomes of human beta -carotene trials are related to the large doses of beta -carotene that were administered. In the present study, ferrets were given a physiological (low) dose or a pharmacological (high) dose of beta -carotene supplementation (0.43 mg versus 2.4 mg/kg body wt/day, which is equivalent to 6 mg versus 30 mg/day in humans) and exposed to cigarette smoke for 6 months. We investigated the effects of these doses of beta -carotene on retinoid concentrations, expression of retinoic acid receptors (RARs), activator protein 1 (AP-1; c-Jun and c-Fos), cyclin D1, proliferating cellular nuclear antigen (PCNA), and histopathological changes in the lungs of both normal and cigarette smoke-exposed ferrets. Thirty-six male ferrets were treated in six groups control, smoke-exposed (SM), low-dose beta -carotene (LBC), high-dose beta -carotene (HBC), low-dose beta -carotene plus smoke exposure (LBC+SM) or high-dose beta -carotene plus smoke exposure (HBC+SM) - for 6 months. Retinoic acid concentration and RAR beta gene expression, but not expression of RAR alpha and RAR gamma , was reduced in the lung tissue of HBC+SM, HBC, SM and LBC+SM ferrets, but not in that of LBC ferrets, as compared with the control group. Expression of AP-1 and PCNA was greater in HBC+SM, HBC, SM and LBC+SM ferrets, but not in the LBC ferrets, as compared with the control group. Increased amounts of cyclin D1 and keratinized squamous metaplasia were observed in the lung tissue of HBC+SM, HBC and SM groups but not in that of the LBC+SM, LBC or control groups. These data suggest that, in contrast with a pharmacological dose of beta -carotene, a physiological dose of beta -carotene in smoke-exposed ferrets has no potentially detrimental effects and may afford weak protection against lung damage induced by cigarette smoke.

S-(+)-Ipsdienol reduced the numbers of I. latidens captured in ( plus or minus )-ipsenol-baited funnel traps relative to funnel traps immediately above them and to control tall-traps. The combination of ( plus or minus )-exo-brevicomin and cis- and trans-verbenol reduced the numbers of I. pini captured in ( plus or minus )-ipsdienol-baited funnel traps relative to funnel traps immediately above them and to control tall-traps. These results provide support for semiochemical-based pest-management tactics that utilize a point source of interruptant at the base of a tree while noting limitations in behavioural effects and efficacy.

Two sets of primers were used to amplify a junctional segment of virulence genes sipB and sipC of Salmonella and an intragenic segment of gene eae of Ecoli O157:H7. Fluorogenic reporter probes were included in the PCR assay for automated and specific detection of amplified products. The assay could detect <10 CFU of Salmonella enterica serovar Typhimurium or E. coli O157:H7 per g of meat or feces artificially inoculated with these pathogens and cultured for 6 to 18 h in a single enrichment broth. Detection of amplification products could be completed in <4 h after enrichment.

Conspecific males and, to a lesser extent, females and nymphs were attracted to blends containing the female-specific essential pheromone components 2-methylbutyl butyrate and (E)-2-methyl-2-butenyl butyrate, whereas individuals of Alydus pilosulus Herrick-Schaeffer were not attracted. When attacked, however, alydid adults emit chemicals for defense--butyric and hexanoic acids in A. eurinus--from the metathoracic scent glands. Mimicry is actually the first line of defense for most broad-headed bugs, including the common North American species studied here, whose nymphs are remarkable ant mimics and whose adults strongly resemble spider wasps (Hymenoptera: Pompilidae). The possibility that disparate heteropterans (Hemiptera) produce sexual pheromones in their metathoracic scent glands must be considered in future pheromone research on heteropterans, especially for species with the specialized lines of defense indicated by aposematism or mimicry.

Reforestation of these abandoned lands, both natural and managed, has been proposed as a means to help offset increasing carbon emissions to the atmosphere. In this paper we discuss the potential of these forests to serve as sinks for atmospheric carbon dioxide in aboveground biomass and soils. A review of literature data shows that aboveground biomass increases at a rate of 6. 2 Mg ha super(-1) yr super(-1) during the first 20 years of succession, and at a rate of 2. 9 Mg ha super(-1) yr super(-1) over the first 80 years of regrowth. During the first 20 years of regrowth, forests in wet life zones have the fastest rate of aboveground carbon accumulation with reforestation, followed by dry and moist forests. Soil carbon accumulated at a rate of 0. 41 Mg ha super(-1 )yr super(-1) over a 100-year period, and at faster rates during the first 20 years (1. 30 Mg carbon ha super(-1) yr super(-1)). Past land use affects the rate of both above- and belowground carbon sequestration. Forests growing on abandoned agricultural land accumulate biomass faster than other past land uses, while soil carbon accumulates faster on sites that were cleared but not developed, and on pasture sites. Our results indicate that tropical reforestation has the potential to serve as a carbon offset mechanism both above- and belowground for at least 40 to 80 years, and possibly much longer. More research is needed to determine the potential for longer-term carbon sequestration for mitigation of atmospheric CO emissions.

Input databases were developed with three different resolutions; agro-ecological zone (AEZ) polygons, 7.6 km and 1.1 km pixels; from archived satellite data commonly used by Early Warning Systems (EWS) to simulate maize yield and production in Kenya from 1989 to 1997. Simulated production results from the GIS-based CSWB model were compared to historical maize production reports from two Government of Kenya (GoK) agencies. The coefficients of determination (r super(2)) between the model and GoK district reports ranged from 0.86 to 0.89. The results indicated the 7.6 km pixel-by-pixel analysis was the most favorable method due to the Rainfall Estimate (RFE) input data having the same resolution. The GIS-based CSWB model developed by this study could also be easily expanded for use in other countries, extended for other crops, and improved in the future as satellite technologies improve.

In this study we investigated two possible explanations for limber pine's success across a broad range of elevations: (1) the sites on which it is found, although separated by >1000 m elevation, may not be very different with respect to environmental factors that affect tree growth, and (2) limber pine growth is insensitive to environmental factors that change with elevation. We compared site characteristics of 12 limber pine stands at elevations ranging from 1630 to 3328 m as well as the growth and morphology of trees in each of these stands. Mean daily air temperature in July decreased linearly with the elevation of the site from 22.8 degree to 12.6 degree C. The growth and morphology of limber pine leaves, shoots, and trees were, in general, not related to the elevation or July mean air temperature of the sites. There was, however, a significant decrease in stomatal density with increasing elevation, which may be an acclimational response to restrict water loss at high elevations. Our data suggest that the fundamental and realized niche of limber pine is broad with respect to air temperature. In light of the high gene flow and only slight genetic differentiation among populations of species with bird-dispersed seeds, such as limber pine, it is especially unusual to see similar growth throughout an environmental gradient. Physiological and anatomical plasticity or wide physiological tolerance ranges may enable limber pine to uncouple its growth from its environment.

One-year-old seedlings were planted and weeds allowed to germinate from the native seed bank while being exposed to CO sub(2) (ambient and elevated - approximately 700 ppm) and water (water stressed and well watered) treatments for approximately one growing season in a greenhouse. Elevated CO sub(2) did not influence total weed biomass; however, C sub(3) weed community development was favored over C sub(4) weed community development in elevated CO sub(2) regardless of water availability. This suggests that weed community composition may shift toward C sub(3) plants in a future elevated CO sub(2) atmosphere. Pine growth was significantly greater in the well watered and elevated CO sub(2) treatments compared to the water stressed and ambient treatments, respectively, even though they were competing with native herbaceous weeds for resources. There was a significant water and CO sub(2) interaction for pine root:shoot ratio. Under elevated CO sub(2), root:shoot ratio was significantly greater in the water stressed treatment than the well watered treatment. In contrast, there was no significant difference in the root:shoot ratio under the ambient CO sub(2) treatment for either water treatment. These results suggest that loblolly pine seedlings will respond favorably in an elevated CO sub(2) atmosphere, even under dry conditions and competing with herbaceous weeds.

Genetic sexing strains both reduce the costs associated with mass rearing and enhance the mating effectiveness of sterile males. Research and application of genetic sexing strains has been limited largely to the Mediterranean fruit fly. However, translocation-based genetic sexing strains based on pupal color mutants have been constructed in the oriental fruit fly, Bactrocera dorsalis (Hendel). Here, we describe the results of laboratory tests on B. dorsalis that compared the relative success of males from a translocation-based sexing strain and wild males in mating competition for wild females. Additional tests examined the effect of irradiation and exposure to methyl eugenol on the mating frequency of males from the genetic sexing strain.

Immature development time and survival, adult longevity, fecundity, and cannibalism were simulated. The model was validated at ambient environmental conditions during three seasons in Wisconsin. The model accurately simulated development of the predator feeding on larvae of the Indianmeal moth, Plodia interpunctella (Huebner) (Lepidoptera: Pyralidae), in the validation studies. The model will be useful in optimizing mass-rearing and augmentative releases of this predator for biological control of stored-product insect pests.

In Y-tube olfactometer bioassays, female R. xylophagorum were attracted to infested bark (i.e., phloem, cambium, and outer corky bark tissues) removed from bolts of loblolly pine, Pinus taeda L., colonized by the late instar larvae and pupae of the bark beetle Ips grandicollis Eichhoff (Coleoptera: Scolytidae). In contrast, bark taken from recently cut, uninfested bolts interrupted attraction to infested bark when these were presented together. Larval and pupal hosts isolated from infested bark were not attractive to parasitoids, whereas frass removed from the larval mines in infested bark was highly attractive. Bark from which hosts or both hosts and host frass were removed remained highly attractive. Bark sandwiches (fresh bark with the exposed surface pressed to glass microscope slides) infested with either third-instar or adult female I. grandicollis were attractive to female parasitoids, whereas bark sandwiches with only mechanical damage to the phloem tissue were unattractive. A steam distillate of bark infested with host larvae was attractive to female R. xylophagorum, whereas a distillate of fresh pine resin was not attractive. Volatiles from the experimental baits were collected on Porapak Q and analyzed by coupled gas chromatography-mass spectrometry. Several compounds were identified that distinguished baits with biological activity. These data show the importance of the complete host/plant complex for attraction of R. xylophagorum to its host's habitat and suggest a possible role for particular odors from uninfested host plant tissue in directing foraging parasitoids away from locations with few or no hosts.

In the short-term experiment, plant dry mass and shoot 20E pools steadily increased. Root uptake of [ super(14)C]MVA resulted in the stable incorporation of super(14)C radiolabel into whole plant 20E pools, with no significant changes over time. Levels of free and saponifiable phytosterols increased in the shoots while super(14)C-labeled shoot phytosterols remained constant. Unexpectedly, both super(14)C-labeled and unlabeled pools of root phytosterols decreased over time. In the long-term experiment, plant dry mass and shoot 20E levels increased over time, while total super(14)C-labeled 20E pools remained constant. Both root and shoot phytosterol pools increased over time while the super(14)C incorporation in these pools remained constant. Together these experiments indicate that 20E in spinach is metabolically stabile and thus shares this characteristic with plant terpenoids of known defensive function. While little is known about phytosterol turnover in plants, our results suggest that phytosterols can indeed exist in a very dynamic state but may also be stable over time.

Exudate was also collected from maize (Zea mays FRB6) seedlings which were grown hydroponically under aseptic conditions. Exudate fractions of host roots stimulated hyphal branching behind any actively growing hyphal tip of three AM fungi tested (Gigaspora gigantea, G. rosea, and Glomus intraradices). Fractionation patterns obtained from C18 Sepak cartridges loaded with carrot root exudates isolated from roots grown under various phosphorus regimes, TLC analyses, and solubility properties of fractionated components, indicated a range of hydrophilic to hydrophobic hyphal branching stimulators. The 50/70% methanol fraction from a C18 cartridge induced hyphal branching patterns of G. gigantea that were dose dependent and were identical to those observed when germinated G. gigantea spores were grown with host roots in dual culture. Exudate fractions from B. vulgaris inhibited hyphal tip growth, but inhibited hyphal tips formed recovery branches which would allow continued fungal growth. These recovery hyphae were also formed when germinated G. gigantea spores were grown in dual culture with sugar beet roots. The recovery branches induced by non-host roots and the prolific branching induced by host roots have ecological implications.

Virulence-avirulence phenotypes were determined on 14 host lines that are near-isogenic for leaf rust resistance. We found 31 phenotypes among 277 single uredinial isolates in 1996, 56 phenotypes among 989 isolates in 1997, and 43 phenotypes among 989 isolates in 1998. As in previous surveys, regional race distribution patterns showed that the central United States is a single epidemiological unit distinct from the eastern United States. The distinctive racial composition of collections from the southeast, northeast, and Ohio Valley indicate that populations of P. triticina in those areas are not closely connected, suggesting that epidemics originate from localized overwintering sources.

Putative B. sorokiniana- and F. graminearum-resistant plants were selected from both Reliant and Manska cultivars of intermediate wheatgrass to produce four populations. When plants from half-sib families that were selected for resistance were intercrossed and progeny subjected to subsequent selection cycles for B. sorokiniana and F. graminearum resistance, progressively higher percentages of putative resistant seedlings were found for three of the four selected populations compared to the original base populations. In cycle 3 of three populations, 7 to 91% of half-sib families with statistically higher seedling survival rates than the base populations were considered more resistant than the base populations. Thus, progressive improvement in seedling survival was realized for three populations selected for resistance using three cycles of recurrent phenotypic selection among and within half-sib families.

Water quality has been affected by runoff and leaching of phosphorus from poultry litter-amended fields. Phosphorus movement is of major concern because P is a limiting nutrient for eutrophication in surface water. The objectives of this study were to (i) evaluate the ability of Al-rich drinking water treatment residue (DWTR) and iron-rich residue (IRR) to reduce water-soluble P and Bray and Kurtz no. 1-extractable phosphorus (BK-1 P) in poultry litter and three long-term litter-amended soils and (ii) determine the effects of these residues on pH and electrical conductivity (EC) in the amended litter and soils. Poultry litter and soils were treated with four rates of DWTR and IRR and incubated for 7 wk at 25 degree C. Litter and soils were sampled at 2, 4, and 7 wk. Both residue materials increased the pH of the litter and the soils. The DWTR was more effective in reducing both water-soluble P and BK-1 P in litter at all rates. At the 25 and 50 g kg super(-1) rates, reductions in water-soluble P with IRR were comparable with that of DWTR, but DWTR was twice as effective as IRR in reducing BK-1 P concentration. The results showed that water-soluble P and BK-1 P in poultry litter and long-term litter-amended soils can be substantially reduced by incorporating residues rich in Al and Fe; these residues may be useful for reducing P runoff and leaching from poultry litter and litter-amended fields.

P. aphanidermatum and P. myriotylum caused the most severe root rot, the greatest reductions in plant weight, and 42 and 62% plant mortality, respectively. In pathogenicity tests with tomato plants, these four species produced similar plant weight losses and disease ratings to those observed in pepper, but little or no plant mortality. Low incidences of root tip necrosis in pepper plants were observed with P. arrhenomanes, P. catenulatum, P. graminicola, and P. irregulare, but none of these species caused losses in root weight and only P. irregulare reduced shoot weight. P. periplocum, P. spinosum, and Pythium sp. F colonized root tissue of pepper but caused no significant root rot and did not adversely affect growth. Similar trends were observed with tomato, except that P. arrhenomanes caused limited root tip necrosis without affecting plant growth and P. catenulatum, P. graminicola, P. irregulare, P. spinosum, and Pythium sp. F colonized at least some of the plants but did not cause root disease. A significant interaction between temperature and P. aphanidermatum or P. myriotylum was observed on pepper transplants. The greatest reductions in growth occurred at 28 degree C, whereas plant mortality only occurred at 34 degree C.

We measured nutrients, total coliform bacteria, fecal coliform bacteria, fecal streptococci, active and total fungi, and active and total bacteria in water leached through cattle, fish, and swine manure, PAM, PAM + Al(SO sub(4)) sub(3), or PAM + CaO mixtures, and 25-cm sand columns. In the laboratory study, PAM, PAM + Al(SO sub(4)) sub(3), and PAM + CaO treatments reduced total coliform bacteria, fecal coliform bacteria, and fecal streptococci by 10- to 1000-fold in water leached through sand columns. Polyacrylamide + Al(SO sub(4)) sub(3) and PAM + CaO treatments reduced the concentration of NH sub(4), total P, and PO sub(4) by 20 to 60% in leachate when cattle and swine manure were applied. In a field study, after water flowed over all three manure sources and then PAM, PAM + Al(SO sub(4)) sub(3), or PAM + CaO in furrows, total coliform bacteria, fecal coliform bacteria, and fecal streptococci were reduced by 10- to 1000-fold in water flowing 1 and 27 m downstream of the treatments compared with the control treatment. When water flowed over cattle manure and then PAM + Al(SO sub(4)) sub(3) or PAM + CaO, PO sub(4) concentration was reduced by 50 to 70% and total P concentration was reduced by 0 to 75% in water 27 m downstream of the treatments compared with the PAM alone treatment. Polyacrylamide + Al(SO sub(4)) sub(3) and PAM + CaO should be able to reduce the numbers of enteric microorganisms and nutrient concentration in animal wastewater running off animal confinement areas, reducing the amount of these pollutants entering surface and ground waters.

A 5-yr field study determined the long-term effects of land application of paper mill sludge on an agricultural soil. The goal of this study was to determine the responses of soil chemical and physical properties to multiple applications of sludge. Five rates of sludge application were tested, ranging from 0 to 225 Mg ha super(-1) in multiple applications under three management protocols: applied once, applied in alternate years, or applied annually. Results indicate strong relationships between added sludge C and several soil physical properties. Increases or maintenance of soil C were observed when sludge was applied annually or biennially, but little residual effect of the single application was seen after 5 yr. Significant increases were observed in soil aggregation and moisture holding properties at higher rates of sludge application and when cumulative C additions reached 225 Mg ha super(-1) in other sludge application rates. It was concluded that long-term paper mill sludge application can be managed to effect positive changes in soil physical properties that are correlated to soil quality.

Flowers were maintained at 24 degree C with the cut pedicel submerged in a sucrose solution. The bacterium multiplied on inoculated flower stigmas at between approximately 55 and 100% RH but not in the floral cup (hypanthium) until the RH was higher than 80%. To study the effect of free moisture, stigma-inoculated flowers were kept wet for different periods. Flowers became diseased only with wetting, and incidence was high (77%) even when water application was immediately followed by a 52-min drying period. In other experiments with hypanthium-inoculated flowers, RH or sucrose concentration in holding vials was varied to affect psi sub(w) of flower nectar and ovary tissue. Population size of E. amylovora in the hypanthium increased with nectar psi sub(w) following a sigmoidal curve (R super(2) = 0.99). Disease incidence and severity, however, were more closely related to ovary psi sub(w) (R super(2) = 0.85 and 0.91, respectively) than to bacterial population size (R super(2) = 0.25 and 0.67, respectively) as fitted to the quadratic equation. Maximum disease incidence and severity occurred at an ovary psi sub(w) above -2.0 MPa, and disease severity continued to increase above -1.0 MPa. These results were confirmed with detached flowers of Delicious apple and d'Anjou pear. A practical implication is that disease might be partly managed in arid climates by limiting soil irrigation water during bloom and early fruit set.

But whether this is true depends on how trade policies affect the allocation of land among competing uses and how they influence illegal cutting of public forests. A model is presented that allows for forests to be either public or private, and public forests are divided into protected (or managed) and threatened categories. Effects of price changes are shown on each part of the forest. An empirical version of the model is applied to the case of Mexico with NAFTA. Most scenarios considered show that NAFTA will have positive long-run effects on forest cover in Mexico but that this is net of losses on private lands.

In a controlled environment experiment, two cloned tall fescue genotypes (DN2 and DN4) free (E-) and infected (E+) with their naturally occurring endophyte strains were grown in nutrient solutions at low P (3.1 ppm) or high P (31 ppm) concentrations for 21 d. Endophyte infection increased root dry matter (DM) of DN4 by 21% but did not affect root DM of DN2. Under P deficiency, shoot and total DM were not affected by endophyte but relative growth rate was greater in E+ than E- plants. In high P nutrient solution, E+ plants produced 13% less (DN2) or 29% more (DN4) shoot DM than E- plants. Endophyte affected mineral concentrations in roots more than in shoots. Regardless of P concentration in nutrient solution, E+ DN2 accumulated more P, Ca, Zn and Cu but less K in roots than E- plants. When grown in high P nutrient solution, concentrations of Fe and B in roots of E+ DN2 plants were reduced compared with those of E- plants. Concentrations of P, Ca and Cu in roots of DN4 were less, but K was greater in E+ than E- plants. In shoots, E+ DN2 had greater concentrations of Fe and Cu than E- DN2, regardless of P concentration in nutrient solution. Genotype DN4 responded to endophyte infection by reducing B concentration in shoots. Nutrient uptake rates were affected by endophyte infection in plants grown in low P nutrient solution. A greater uptake rate of most nutrients and their transport to shoots was observed in DN2, but responses of DN4 were not consistent. Results suggest that endophyte may elicit different modes of tall fescue adaptation to P deficiency.

Plants were grown to maturity from seed in cores. Cores were periodically leached, allowing for quantification of NO sub(3) super(-) and NH sub(4) super(+) production, and denitrification incubations were conducted before and after cover crop kill. Gas permeable tubing was buried at two depths in cores allowing for quantification of N sub(2)O in the soil profile. Cover crops assimilated most soil N prior to kill. After kill, relative rates of N mineralization were vetch > rye-vetch mixture > fallow > rye. After correcting for N mineralization from fallow cores, net N mineralization was observed in vetch and rye-vetch cores, while net N immobilization was observed in rye cores. Denitrification incubations were conducted 5, 15 and 55 days after kill, with adjustment of cores to 75% water filled pore space (WFPS). The highest denitrification was observed in vetch cores 5 days after kill, when soil NO sub(3) super(-) and respiration rates were high. Substantially lower denitrification was observed on subsequent measurement dates and in other treatments probably due to either limited NO sub(3) super(-) or organic carbon in the soil. On day 5, 3%, 23%, 31% and 31% of the N sub(2)O was recovered in the headspace of fallow, vetch, rye and rye-vetch cores, respectively. The rest was stored in the soil profile. In a field study using intact soil cores, denitrification rates also peaked 1 week after cover crop kill and decreased significantly thereafter. Results suggest greater potential N losses from vetch than rye or rye-vetch cover crops due to rapid N-mineralization in conjunction with denitrification and potential leaching, prior to significant crop N-assimilation.

AN - 70777315; 11069297 AB - Net photosynthesis (Pn) is inhibited by moderate heat stress. To elucidate the mechanism of inhibition, we examined the effects of temperature on gas exchange and ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco) activation in cotton and tobacco leaves and compared the responses to those of the isolated enzymes. Depending on the CO(2) concentration, Pn decreased when temperatures exceeded 35-40 degrees C. This response was inconsistent with the response predicted from the properties of fully activated Rubisco. Rubisco deactivated in leaves when temperature was increased and also in response to high CO(2) or low O(2). The decrease in Rubisco activation occurred when leaf temperatures exceeded 35 degrees C, whereas the activities of isolated activase and Rubisco were highest at 42 degrees C and >50 degrees C, respectively. In the absence of activase, isolated Rubisco deactivated under catalytic conditions and the rate of deactivation increased with temperature but not with CO(2). The ability of activase to maintain or promote Rubisco activation in vitro also decreased with temperature but was not affected by CO(2). Increasing the activase/Rubisco ratio reduced Rubisco deactivation at higher temperatures. The results indicate that, as temperature increases, the rate of Rubisco deactivation exceeds the capacity of activase to promote activation. The decrease in Rubisco activation that occurred in leaves at high CO(2) was not caused by a faster rate of deactivation, but by reduced activase activity possibly in response to unfavorable ATP/ADP ratios. When adjustments were made for changes in activation state, the kinetic properties of Rubisco predicted the response of Pn at high temperature and CO(2).

Utilizing regional groundwater models in the management of these water resources requires accurate estimates of basin boundary conditions. A critical groundwater boundary condition that is closely coupled to atmospheric processes and is typically known with little certainty is seasonal riparian evapotranspiration (ET). This quantity can often be a significant factor in the basin water balance in semi-arid regions yet is very difficult to estimate over a large area. Better understanding and quantification of seasonal, large-area riparian ET is a primary objective of the Semi-Arid Land-Surface-Atmosphere (SALSA) Program. To address this objective, a series of interdisciplinary experimental campaigns were conducted in 1997 in the San Pedro Basin in southeastern Arizona. The riparian system in this basin is primarily made up of three vegetation communities: mesquite (Prosopis velutina), sacaton grasses (Sporobolus wrightii), and a cottonwood (Populus fremontii)/willow (Salix goodingii) forest gallery. Micrometeorological measurement techniques were used to estimate ET from the mesquite and grasses. These techniques could not be utilized to estimate fluxes from the cottonwood/willow (C/W) forest gallery due to the height (20-30 m) and non-uniform linear nature of the forest gallery.

Virtually all risk is borne by native plant species that are closely related to target weeds. Fifteen species of insects introduced for biological control use 41 native plant species; 36 of which are congeneric with target weeds, while 4 others belong to two closely allied genera. Only 1 of 117 established biological organisms uses a native plant unrelated to the target weed. Thus the elements of protection for the native flora are the selection of weed targets that have few or no native congeners and the introduction of biological control organisms with suitably narrow diets.

This paper summarizes research on the effects and outcomes of hurricanes on Caribbean forests. Twelve effects and outcome topics are presented: sudden and massive tree mortality; delayed patterns of tree mortality; alternative methods of forest regeneration; opportunities for a change in successional direction; high species turnover and opportunities for species change in forests; diversity of age classes; faster biomass and nutrient turnover; species substitutions and changes in turnover time of biomass and nutrients; lower aboveground biomass in mature vegetation; carbon sinks; selective pressure on organisms; and convergence of community structure and organization. Effects of hurricanes on urban systems are also discussed. While there is scientific uncertainty as to whether hurricane frequencies and intensity will change as a result of global climate change, available understanding on the effects and outcomes of hurricanes can be used to anticipate possible effects of either increasing or decreasing hurricane frequency and intensity. Proposed mitigation actions and research priorities can be effective and desirable even if the frequency and intensity of hurricanes remains unchanged.

AN - 72501876; 11128131 AB - A multiresidue method was developed for the determination of fluoroquinolones in eggs. Extraction of eggs with ammoniacal acetonitrile was followed by liquid-liquid defatting, solvent evaporation, and redissolution in a small volume of buffer. The fluoroquinolones were further purified by on-line microdialysis, concentrated on a trace enrichment column, and separated by reversed-phase liquid chromatography with fluorescence detection. Norfloxacin (NOR), ciprofloxacin (CIP), and sarafloxacin (SAR) were extracted from fortified eggs over a range of 2-200 microg/kg, with recoveries of 65.7-78.9%, 65.6-77.1%, and 67.6-110%, respectively. Enrofloxacin (ENRO) was extracted over a range of 1-100 microg/kg, with recoveries of 71.5-86.7%, whereas desethylene ciprofloxacin (DCIP) and danofloxacin (DANO) were extracted over a range of 0.2-20 microg/kg, with recoveries of 68.7-90.7% and 76.0-93.8%, respectively. The limits of quantitation for the 6 fluoroquinolones were as follows: DCIP and DANO, 0.3 microg/kg; ENRO, 1 microg/kg; NOR and CIP, 2 microg/kg; and SAR, 3 microg/kg. Both SAR and ENRO incurred eggs were also successfully analyzed using this method.

AN - 72483302; 11126544 AB - White-tailed deer treated themselves with a commercial pour-on acaricide formulation containing 2% amitraz as they fed from an ARS-patented '4-poster' topical treatment device. Whole kernel corn attracted deer to a single device placed in each of two deer-fenced pastures. In the treatment pasture, the rollers of the treatment device were charged with the acaricide, whereas the rollers of the device in the other pasture remained untreated. Deer were allowed to use the '4-posters' during periods of tick activity beginning in early to midspring and lasting through late summer to early fall for three consecutive years. Pretreatment sampling of adults and nymphs with dry-ice traps and larval masses with flip cloths showed no significant differences in population indices between the two pastures; however, after the third year of treatment, control of nymphal and adult ticks in the treated pasture was 91.9 and 93.7%, respectively, when compared with the untreated pasture. Control of larval masses increased from 68.4% in year 1 to 96.4% in year 2, but declined to 88.0% in year 3, probably because of the presence of feral hogs. This study demonstrated that application of amitraz to white-tailed deer through free-choice interaction with a '4-poster' device significantly reduced the abundance of free-living lone star ticks in a deer-fenced experimental pasture. Moreover, the yearly pattern of incremental increases in control and the final percentage control values for all three parasitic life stages in this topical application study were similar in magnitude to that observed in a previously conducted study in which the systemic acaricide ivermectin was used to reduce populations of free-living ticks by controlling ticks on deer.

This paper reviews the published research studies on a) the penetration and proliferation of salmonellae in hatching eggs, b) the consequences of this contamination on the contamination of the final product, and c) the egg's defenses against invading salmonellae. A better understanding of the material in this review paper will assist poultry researchers and the poultry industry in continuing to make progress in reducing and eliminating salmonellae from fertile hatching eggs, hatcheries, and breeder flocks.

AN - 72421682; 11080287 AB - Plants accumulate crystals of calcium oxalate in a variety of shapes, sizes, amounts, and spatial locations. How and why many plants form crystals of calcium oxalate remain largely unknown. To gain insight into the regulatory mechanisms of crystal formation and function, we have initiated a mutant screen to identify the genetic determinants. Leaves from a chemically mutagenized Medicago truncatula population were visually screened for alterations in calcium oxalate crystal formation. Seven different classes of calcium oxalate defective mutants were identified that exhibited alterations in crystal nucleation, morphology, distribution and/or amount. Genetic analysis suggested that crystal formation is a complex process involving more than seven loci. Phenotypic analysis of a mutant that lacks crystals, cod 5, did not reveal any difference in plant growth and development compared with controls. This finding brings into question the hypothesized roles of calcium oxalate formation in supporting tissue structure and in regulating excess tissue calcium.

AN - 72387892; 11058686 AB - Several laboratories have determined the surface charge density of membranes utilizing methods based on vesicle-induced quenching of the fluorescence of 9-aminoacridine and its relief by other cations. However, the computational methods by which surface charge density were calculated have not been verified in a model system. In this study, the quenching of 9-aminoacridine fluorescence by liposomes made from varying amounts of digalactosyldiacylglyceride and phosphatidic acid and relief of quenching by salts was examined. Quenching of 9-aminoacridine fluorescence increased with increasing amounts of phosphatidic acid added, independent of the composition of the added liposomes. In certain instances, the computational methods did not yield the surface charge density of the liposomes expected from their composition. However, when the effects of background ionic strength on surface potential were considered, there was a positive correlation between expected and calculated values. Therefore, the data support the contention that changes in the fluorescence of 9-aminoacridine can be used to calculate surface charge density of membranes.

AN - 72387692; 11063315 AB - Nine barrows (23.8 +/- 0.9 kg) and 9 gilts (23.1 +/- 0.9 kg) were used to determine the disposition of radiocarbon after oral [14C]clenbuterol (4-amino-alpha-[t-butylaminomethyl]-3,5-dichlorobenzyl [7-(14)C]alcohol hydrochloride) administration and to determine total and parent residues in edible tissues. Three barrows and three gilts, housed in metabolism crates, were fed 1 ppm [14C]clenbuterol HCl for seven consecutive days in three separate trials; a single barrow and gilt from each trial was slaughtered after 0-, 3-, or 7-d preslaughter withdrawal periods. Urine and feces were collected during the dosing and the withdrawal period; edible and inedible tissues were collected at slaughter. Total recovery of radiocarbon was 94.2 +/- 6.5%. Total clenbuterol absorption was greater than 75% for barrows and 60% for gilts. Total radioactive residues in tissues were not different (P > 0.05) between barrows and gilts. Concentrations of parent clenbuterol in liver, kidney, skeletal muscle, adipose tissue, and lung did not differ between barrows and gilts (P > 0.05). Total radioactive and parent residues declined in tissues as withdrawal period increased. After the 0-d withdrawal period, total liver residues (286 ppb) were approximately equal to lung residues, twice those of the kidney, and about 15 times those of adipose tissue and skeletal muscle. After a 7-d withdrawal period, total radioactive residues in liver (15 ppb) were roughly three times greater than lung, kidney, and adipose tissue total residues and about 13 times those of skeletal muscle total residues. Parent clenbuterol represented 79, 63, 42, 67, and 100% of the total radioactive residue in adipose tissue, kidney, liver, lung, and skeletal muscle, respectively, in hogs slaughtered with a 0-d withdrawal period. With increasing withdrawal period, the percentage of total radioactive residue present as parent clenbuterol within edible tissues (including lung) decreased, so that after a 7-d withdrawal period, 7, 16, and 29% of the total residue was composed of parent clenbuterol in kidney, liver, and lung, respectively. After a 7-d withdrawal period, parent clenbuterol exceeded the European maximum residue limit (0.5 ppb) 4.6-fold in liver and 2.4-fold in lung. In muscle, clenbuterol was approximately 40 times the limit after a 0-d withdrawal period but had dropped below 0.5 ppb after a 3-d withdrawal period. Results from this study indicate that clenbuterol HCl is well absorbed in swine and that the use of clenbuterol in this species in an off-label manner is inconsistent with human food safety standards used in developed countries.

AN - 72373258; 11057568 AB - Two long-term no-till corn production studies, representing different soil texture, consistently showed higher leaching of atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine] to groundwater in a silt loam soil than in a sandy loam soil. A laboratory leaching study was initiated using intact soil cores from the two sites to determine whether the soil texture could account for the observed differences. Six intact soil cores (16 cm dia by 20 cm high) were collected from a four-year old no-till corn plots at each of the two locations (ca. 25 km apart). All cores were mounted in funnels and the saturated hydraulic conductivity (Ksat) was measured. Three cores (from each soil texture) with the lowest Ksat were mixed and repacked. All cores were surface treated with 1.7 kg ai ha(-1) [ring-14C] atrazine, subjected to simulated rainfall at a constant 12 mm h(-1) intensity until nearly 3 pore volume of leachate was collected and analyzed for a total of 14C. On an average, nearly 40% more of atrazine was leached through the intact silt loam than the sandy loam soil cores. For both the intact and repacked cores, the initial atrazine leaching rates were higher in the silt loam than the sandy loam soils, indicating that macropore flow was a more prominent mechanism for atrazine leaching in the silt loam soil. A predominance of macropore flow in the silt loam soil, possibly due to greater aggregate stability, may account for the observed leaching patterns for both field and laboratory studies.

AN - 72263183; 10989298 AB - Reverse transcriptase-polymerase chain reaction (PCR) was used to clone two esterase cDNAs from a diazinon-resistant field population of horn flies that expresses qualitative and quantitative differences in esterases compared with a susceptible population. The open reading frame from one of the esterase cDNAs, HialphaE7, exhibits substantial amino-acid identity to an esterase associated with diazinon resistance in Lucilia cuprina. RNA Northern blots showed that HialphaE7 mRNA was more abundant in the diazinon-resistant population than the susceptible population. DNA copy number analysis did not reveal major differences in HialphaE7 gene copy number between the two populations. The full-length cDNA to HialphaE7 was cloned and sequenced, and found to contain all of the highly conserved sequence elements associated with carboxyl/cholinesterases. The HialphaE7 homologs in diazinon-resistant strains of L. cuprina and Musca domestica have been shown to possess an amino-acid substitution conferring diazinon hydrolytic activity to the esterase enzyme. This amino-acid substitution was not found in diazinon-resistant horn flies examined by allele-specific PCR. Individual flies from the resistant field population were phenotyped as diazinon-resistant or diazinon-susceptible by topical diazinon application bioassays and total RNA isolated and hybridized to HialphaE7 probe in ribonuclease protection assays. HialphaE7 transcript was expressed at a five-fold higher level in resistant female individual flies than in susceptible female individuals.

Corn was processed into tortillas, starting with raw corn that was cooked with lime and allowed to steep overnight; the steeped corn (nixtamal) was washed and ground into masa, which was used to make tortillas. Calculations to determine how much of the original fumonisin remained in the finished products took into consideration that FB(1) will be converted to hydrolyzed fumonisin B(1) (HFB(1)) by the process of alkaline cooking. All fractions, including steeping and washing water, were weighed, and percent moisture and fumonisin content were determined. Tortillas contained approximately 0.50 ppm of FB(1), plus 0.36 ppm of HFB(1), which represented 18.5% of the initial FB(1) concentration. Three-fourths of the original amount of fumonisin was present in the liquid fractions, primarily as HFB(1). Nixtamalization significantly reduced the amount of fumonisin in maize.

AN - 70764836; 11087553 AB - Fumonisins are polyketide mycotoxins produced by Fusarium verticillioides (synonym F. moniliforme), a major pathogen of maize (Zea mays) worldwide. Most field strains produce high levels of fumonisin B(1) (FB(1)) and low levels of the less-oxygenated homologues FB(2) and FB(3), but fumonisin B(1)-nonproducing field strains have been obtained by natural variation. To test the role of various fumonisins in pathogenesis on maize under field conditions, one strain producing FB(1), FB(2), and FB(3), one strain producing only FB(2), one strain producing only FB(3), and one fumonisin-nonproducing strain were applied to ears via the silk channel and on seeds at planting. Disease severity on the harvested ears was evaluated by visible symptoms and by weight percent symptomatic kernels. Fumonisin levels in kernels were determined by high-performance liquid chromatography. The presence of the applied FB(1)-nonproducing strains in kernels was determined by analysis of recovered strains for fumonisin production and other traits. All three FB(1)-nonproducing strains were able to infect ears following either silk-channel application or seed application at planting and were as effective as the FB(1)-producing strain in causing ear rot following silk-channel application. These results indicate that production of FB(1), FB(2), or FB(3) is not required for F. verticillioides to cause maize ear infection and ear rot.

This discrimination is achieved by computing thermal band emissivities from a temperature-emissivity separation algorithm, and then classifying surface features based on spectral emissivity contrast. In a study of rangelands and winter wheat fields in central Oklahoma, the contrast, or range, of these spectral emissivities is diagnostic of the presence or absence of surface vegetative cover. A large range of emissivities, approximately greater than 0.03, is indicative of bare soil, while a low range, less than 0.02, is indicative of vegetative cover. When knowledge of the emissivity range is combined with a vegetation index, such as NDVI, the surface may be classified by a ternary system: bare soil, green vegetation, and senescent vegetation. Discrimination between bare soil and soil covered with senescent vegetation using emissivity contrast should be feasible in other settings. The benefit of this technique is that heat flux predictions can be based on a more accurate surface representation than otherwise provided by visible and near-infrared land classification schemes.

Evolutionary relationships among the bradyrhizobia were more resolved using reconstructions derived from ITS than from 16S rRNA gene sequence divergence. Strain USDA 129 was placed together with USDA 62, 110, 122 and 126, but did not cluster with USDA 123 and 127, with which it shares antigenic determinants. The results from the phylogenetic analysis were supported with data from determinations of genetic diversity among additional strains within each of these serogroups using amplified fragment length polymorphism analysis. From these results it was concluded that strains of serogroup 129 were more similar to strains of serogroups 62, 110 and 122 than they were to strains of serogroups 123 and 127. The serotype strain of Bradyrhizobium japonicum USDA 135 and the type strain for Bradyrhizobium liaoningense possessed identical 16S rRNA gene and ITS region sequences. Also, the type strain for B. liaoningense cross-reacted with antisera prepared against somatic antigens of USDA 135. Therefore, it was not possible to distinguish B. liaoningense from serogroup 135 in our analysis of B. japonicum and Bradyrhizobium elkanii.

These species produce a family of cyclic dipeptides, the thaxtomins, which alone mimic disease symptomatology. Structural considerations suggest that thaxtomins are synthesized non-ribosomally. Degenerate oligonucleotide primers were used to amplify conserved portions of the acyladenylation module of peptide synthetase genes from genomic DNA of representatives of the four species. Pairwise Southern hybridizations identified a peptide synthetase acyladenylation module conserved among three species. The complete nucleotide sequences of two peptide synthetase genes (txtAB) were determined from S. acidiscabies 84.104 cosmid library clones. The organization of the deduced TxtA and TxtB peptide synthetase catalytic domains is consistent with the formation of N-methylated cyclic dipeptides such as thaxtomins. Based on high-performance liquid chromatography (HPLC) analysis, thaxtomin A production was abolished in txtA gene disruption mutants. Although the growth and morphological characteristics of the mutants were identical to those of the parent strain, txtA mutants were avirulent on potato tubers. Moreover, introduction of the thaxtomin synthetase cosmid into a txtA mutant restored both pathogenicity and thaxtomin A production, demonstrating a critical role for thaxtomins in pathogenesis.

Minnow traps set for 90-min periods during three or four sequential capture occasions during the summer of 1996 were used to capture coho salmon Oncorhynchus kisutch fry and parr, Dolly Varden Salvelinus malma, cutthroat trout O. clarki, and juvenile steelhead O. mykiss to estimate population size with the Zippin or generalized removal method. More than 45% of the total catch was obtained during the first capture occasion, and in most cases, the catch during the fourth occasion was less than 15% of the total catch. In most pools, the probability of capture was greater than 0.4 but was lower for coho salmon fry than for coho salmon parr and other species. Mean population estimates for coho salmon parr made with concurrent mark-recapture and removal methods differed significantly in small streams. Estimates from mark-recapture and removal methods were not significantly different for coho salmon fry and Dolly Varden, but mark-recapture estimates were higher than removal estimates in most cases. My results show that removal estimates can be obtained with minnow traps if sampling procedures conform to the assumptions required for the method.

The majority of the remaining species are considered important weeds. A new fungal species, Phomopsis amaranthicola, isolated from stem and leaf lesions on an Amaranthus sp. plant, was found to be pathogenic to 22 species of Amaranthus tested. The efficacy of this fungus was tested in field trials using one or two postemergent applications of the fungus consisting of two concentrations of conidia or mycelial suspensions. Species tested for susceptibility in the field included Amaranthus hybridus, A. lividus, A. viridus, A. spinosus, and a triazine-resistant A. hybridus. The cumulative disease incidence data for each treatment within each species were plotted versus time using regression for lifetime data. Plant mortality was recorded 2, 4, and 6 weeks after inoculation. There were significant differences between the treatment effects in the control plots versus the plots treated with P. amaranthicola. The highest level of control was obtained in the first trial when the fungus was applied at 6 x 10 super(7) conidia per ml. Final mortality of all species, except A. hybridus, reached 100% in inoculated plots 25 days earlier than in noninoculated control plots. Conidial suspensions were more effective in controlling the species in the second trial than were mycelial suspensions. Spread of the pathogen to noninoculated control plots was faster in the second year than in other years. High levels of plant mortality were achieved in plots of A. spinosus, A. lividus, and A. viridis. A. hybridus and the triazine-resistant A. hybridus were not effectively controlled in the second year due to the advanced stage of plant growth (8 to 10 true leaves) at the time of pathogen application. Results confirmed that P. amaranthicola is an effective biocontrol agent of some of the Amaranthus spp. tested.

Except for rice and sorghum, most have large, complex genomes, the bulk of which consist of repetitive sequences and retrotransposons (7,53). Thus, much of the early research relating to the molecular study of plant disease resistance has occurred in species with small genomes, such as Arabidopsis, rice, and tomato. The knowledge acquired from these model species has facilitated similar efforts in cereal crops. The goal of this report is to summarize the current tools available and to outline selected examples where these tools have been useful for the investigation of disease resistance in barley (Hordeum vulgare L.). Because molecular investigations have focused primarily on fungal pathogens, they will be the subject of this review.

Fresh mycelial plugs, dry mycelial fragments, and sclerotia of Sclerotinia minor were placed onto the amended media, and mycelial growth and sclerotial germination were determined for 7 days. Thiophanate-methyl was the most effective chemical in inhibiting growth of S. minor, followed by PCNB and dicloran. Thiophanate-methyl was the only chemical that prevented germination of sclerotia of S. minor. Peanut seed naturally infested with S. minor was treated with the fungicides alone or in various combinations; control seed was treated with talcum powder. Seed was stored in polyethylene bags for 12 weeks at 24 degree C. To determine the incidence of viable S. minor in treated seed, seed was removed from bags, washed for 1 min in 0.2% unscented, liquid soap solution, rinsed twice in distilled water, and then dried for 15 min prior to plating on SPDA. The incidence of S. minor in talcum and thiophanate-methyl treated seed was 3.68 and 0.0%, respectively. Incidence of S. minor in seed treated with the other compounds ranged from 0.40 to 0.56%. Subsequent tests were performed using thiophanate-methyl and some of the above chemicals, in combinations or alone. These tests confirmed that thiophanate-methyl was the only compound that consistently reduced recovery of S. minor from infested seed. Germination of thiophanate-methyl treated seed equaled that of seed treated with talcum.

This coating is gradually lost as the larvae drop to the ground and pupate in subterranean pupal cells. To test the antipredator activity of this species, four immature life stages (early instars, late instars, prepupae, pupae) were exposed to a common generalist predator, the red imported fire ant Solenopsis invicta. Choice tests were conducted by placing an O. vitiosa individual and a control larva of the weevil Neochetina eichhorniae into an arena containing a S. invicta colony and observing subsequent ant behaviors. S. invicta workers contacted O. vitiosa early instars, late instars, and prepupae less frequently than control N. eichhorniae larvae, and upon contact S. invicta was less likely to behave aggressively toward these O. vitiosa life stages than toward N. eichhorniae larvae. However, S. invicta contacted, attacked, and consumed naked (nonencased) O. vitiosa pupae and N. eichhorniae larvae with equal frequency. Encased O. vitiosa pupae buried in sand were not attacked compared to susceptible encased pupae on the sand surface. By shifting from a chemical defense during the larval stages to a physical defense during the pupal stage, O. vitiosa reduces the risk of attack by this generalist predator.

In this paper, we use a modified form of the van Genuchten-Mualem (VGM) soil hydraulic functions to account for a very small, but non-zero minimum capillary height, h sub(s), in the soil water retention curve. The modified VGM model is contrasted with the original formulation by comparing simulation results for infiltration in homogeneous soils assuming both constant pressure and constant flux boundary conditions. The two models gave significantly different results for infiltration in fine-textured soils, even for h sub(s)-values as small as -1 cm. Incorporating a small minimum capillary height in the hydraulic properties leads to less non-linearity in the hydraulic conductivity function near saturation and, because of this, to more stable numerical solutions of the flow equation. This study indicates an urgent need for experimental studies that assess the precise shape of the hydraulic conductivity curve near saturation, especially for relatively fine-textured soils. For one example we found considerable improvement in the predicted conductivity function when a value of -2 cm for h sub(s) was used in the modified VGM model.

(Heteroptera: Pentatomidae) AN - 17764164; 4819224 AB - Control females of the twospotted stink bug, Perillus bioculatus (F.), and those given an artificial diet mated repeatedly over their lifetimes when held with males. The average number of observed matings was 4 and 8.4 in the controls and those given the artificial diet, respectively. Mating and an adequate diet are prerequisites for laying a full compliment of eggs in this insect. Virgins laid an average of 22 eggs compared with 138 in the multiply mated controls, 84 in singly mated females and 42 in multiply mated females given an artificial diet. The number of clutches deposited was not significantly affected by treatment, but the number of eggs per clutch was significantly lower in virgins and those given the artificial diet than in the controls or once mated females. The number of eggs per clutch showed no significant changes as the female aged. Oviposition rates were calculated over 5-d periods for each female and presented as eggs per day. In all experimental groups the number of eggs deposited per interval decreased as the females aged. By 27.5 d after the start of oviposition, females from all treatments laid one or fewer eggs per day. The decrease in eggs per day deposited by females as they aged is attributed to an increase in the time between clutch deposition. Egg viability showed no significant differences among the multiply mated controls, once mated females, or the multiply mated females given the artificial diet. This suggests that multiple mating is not required to maintain egg viability, but is necessary to maintain oviposition over the lifetime of the female. Low numbers of eggs oviposited by females given the artificial diet is attributed to the production of fewer mature follicles than in the controls and not to an impairment of the process of oviposition. In contrast, the lower number of eggs laid by virgin females results from an impairment of the oviposition process and not the impairment of ovarian follicle maturation.

Camphor and menthol were the most effective of the monoterpenoids tested. Y-tube olfactometer bioassays revealed that beetles spent significantly more time (within 10-min observation periods) in the untreated control arm than in the arm containing camphor or menthol (both at 100 and 1,000 mu g). Another olfactometer bioassay revealed that significantly more beetles remained in the untreated control arm than in the arm containing camphor or menthol (142 mu g), within 45-min observation periods. When camphor (9.4% emulsified concentrate) was sprayed onto crevices on the exterior of a building through which beetles were entering, 100% of approaching beetles were repelled for the duration of the tests (0.5 h, two replicates). In another field experiment, significantly fewer H. axyridis were captured in traps containing camphor versus un-baited control traps. Research is continuing to develop a protocol for repelling nuisance beetle aggregations and conserving the beetles for biological control applications.

The interaction of these forces control streambank mechanics. Hydraulic forces exerted by flowing water on in situ bank-toe material and failed cohesive material at the bank toe are often sufficient to entrain materials at relatively frequent flows and to maintain steep lower-bank profiles. Seepage forces exerted on in situ bank material by groundwater, downward infiltration of rainwater and lateral seepage of streamflow into and out of the bank are critical in determining bank strength. Data from a study site on Goodwin Creek, MS, USA clearly show the temporal variability of seepage forces and the lag time inherent in reductions in shear strength due to losses of matric suction and generation of positive pore-water pressures. Negative pore-water pressures (matric suction) have also been shown to increase the resistance of failed cohesive blocks to entrainment by fluid shear. A stable bank can be transformed into an unstable bank during periods of prolonged rainfall through: 1. increase in soil bulk unit (specific) weight, 2. decrease or complete loss of matric suction, and, therefore, apparent cohesion, 3. generation of positive pore-water pressures, and, therefore, reduction or loss of frictional strength, 4. entrainment of in situ and failed material at the bank toe, and 5. loss of confining pressure during recession of stormflow hydrographs. Relatively small frequent flows during the winter have the ability to erode failed bank materials, maintain oversteepened, unstable bank surfaces and promote prolonged periods of bank retreat, channel migration and high yields of fine-grained sediment. Confining pressures provided by stormflow are not as significant in maintaining bank stability as the counteracting force of fluid shear on the bank toe, which steepens the bank. For example, more than 2 m of bank retreat occurred during the study period at the research site on Goodwin Creek, northern Mississippi. The loss of matric suction (negative pore pressures) due to infiltrating precipitation has been found to be as significant as the development of excess pore pressures in contributing to mass bank instability. Apparent cohesion, friction angle, soil bulk unit weight and moisture content were measured in situ. Matric suction was measured continuously, in situ with a series of five pressure-transducer tensiometers. A bank-failure algorithm, which combines the Mohr-Coulomb approach, for saturated conditions and the Fredlund modification for unsaturated conditions was developed for layered cohesive streambanks. The resulting equation has been used successfully to investigate the role of matric suction, positive pore-water pressures and confining pressure for layered streambanks composed of cohesive materials.

Carboxylation efficiency and area-based leaf N content were substantially higher at treeline than at lower elevations while leaf size and instantaneous photosynthetic nitrogen-use efficiency (PNUE) were substantially lower at treeline. For example, PNUE decreased from 45 mu mol CO sub(2) mol N super(-1) at low elevation to 17.4 mu mol CO sub(2) mol N super(-1) at high elevation. In contrast, average net CO sub(2) assimilation and integrated PNUE remained relatively constant along the elevation gradient despite suboptimal temperatures and decreased soil nitrogen availability at treeline. These and other homeostatic mechanisms allow M. polymorpha to maintain a relatively high level of growth-related activities at treeline despite frequent near- and below-freezing temperatures. High-elevation populations avoided freezing by supercooling apparently as a result of small leaves, reduced intercellular spaces, and low apoplastic water content in leaves. Ice nucleation temperatures were about -8.5 degree C for leaves of treeline populations, 3 degree C lower than those of low elevation populations. Irreversible tissue damage temperature decreased 7 degree C from sea level to treeline. However, the decrease appeared to be only large enough to allow M. polymorpha trees to avoid leaf tissue damage due to freezing up to the current location of treeline. All of the above leaf traits in high-elevation populations serve to promote carbon gain in a nutrient and temperature limited environment as well as to avoid freezing by supercooling.

Studies of red spruce (Picea rubens Sarg.) have shown that rates of field photosynthesis (P sub(field)) and laboratory measurements of photosynthetic capacity (P sub(max)) generally parallel seasonal ambient temperature trends; carbon exchange decreases in the fall, remains negative or close to zero for much of the winter, and increases in the spring. However, increases in P sub(field), P sub(max), and foliar carbohydrate concentrations can occur during winter thaws. Thaw- induced increases in photosynthesis are probably not the result of increased stomatal conductance, but may result from other changes in physiology associated with thaw-induced improvements in water relations. In addition to increased photosynthesis, red spruce also decrease in cold hardiness during thaws. The co-occurrence of thaw-induced changes in photosynthesis and cold hardiness raises questions regarding their adaptive significance, particularly in the context of potential climate change. Red spruce may face a tradeoff between potentially beneficial increases in carbon capture and potentially detrimental reductions in cold tolerance. The physiological consequence(s) of this tradeoff may depend on the number and duration of thaws, as well as ambient temperature trends following thaw. Pollution-induced reductions in cold tolerance, and the low genetic variability of red spruce, may also influence the net outcome of thaw-induced changes in physiology.

These mechanisms of biological control have been difficult to study because no method has been available to determine the significance of each of the components of competition. We developed a nondestructive method using tissue culture plates with cylinder inserts containing defusing membrane at one end to study competition for nutrients without competition for space. Other biocontrol mechanisms in which direct contact between an antagonist and a pathogen is not required also can be studied. The method was used to determine the competition between the yeastlike biocontrol agent, Aureobasidium pullulans, and Penicillium expansum for limited nutrients in apple juice during 24 h incubation, simulating a fruit wound. The antagonist depleted amino acids and inhibited germination of P. expansum conidia. Exposing these conidia to fresh apple juice increased conidial germination to the level comparable to that exhibited by conidia which were not exposed to the antagonist. Because the culture plate method was nondestructive, follow-up experiments in an agar diffusion test were conducted. Juice in which the antagonist grew did not inhibit germination of P. expansum conidia that were seeded on the plates. This corroborates findings from the culture plate method that inhibition of the conidia germination resulted from competition for nutrients. The new method can be coupled with existing techniques to improve understanding of antagonist-pathogen interaction for biological control of postharvest diseases.

One of the main barriers to the advancement of this area of plant biology has been the paucity of simple and appropriate experimental models that would enable the researcher to biochemically and genetically dissect the response of less complex plants to environmental stress. A number of bryophytes model systems have been developed and they have been powerful experimental tools for the elucidation of complex biological processes in plants. Recently there has been a resurgent interest in bryophytes as models systems due to the discovery and development of homologous recombination technologies in the moss Physcomitrella patens (Hedw.) Brach & Schimp. In this report we introduce the desiccation-tolerant moss Tortula ruralis (Hedw.) Gaert., Meyer, and Scherb, as a model for stress tolerance mechanisms that offers a great deal of promise for advancing our efforts to understand how plants respond to and survive the severest of stressful environments. T. ruralis, a species native to Northern and Western North America, has been the most intensely studied of all bryophytes with respect to its physiological, biochemical, and cellular responses, to the severest of water stresses, desiccation. It is our hope that the research conducted using this bryophyte will lay the foundation for not only the ecology of bryophytes and other less complex plants but also for the role of desiccation-tolerance in the evolution of land plants and the determination of mechanisms by which plant cells can withstand environmental insults. We will focus the discussion on the research we and others have conducted in an effort to understand the ability of T. ruralis to withstand the complete loss of free water from the protoplasm of its cells.

Exposures to mercury via fish were studied in an indigenous community of the Munduruku reserve, located in the Tapajos River basin in the state of Para, one of the oldest and most productive gold mining areas in the Amazon region. This study summarizes the results of mercury (Hg) analyses of fish consumed by inhabitants of the Munduruku settlement of Sai Cinza. The most frequently consumed fish, reported by 330 persons interviewed for this study, were tucunare, pacu, jaraqui, traira, aracu, matrincha, and caratinga. The mean mercury concentration in carnivorous fish was 0.297 mu g[sdot]g super(-1) while in noncarnivorous fish mean mercury concentration was 0.095 mu g[sdot]g super(-1). Only in caratinga was there a significant relationship between fish size, weight, and mercury levels. Levels of methylmercury in the tucunare averaged 0.170 mu g[sdot]g super(-1), while in traira the mean level of methylmercury was 0.212 mu g[sdot]g super(-1). Although the levels of Hg in fish consumed by the Sai Cinza community are below the Brazilian limit value for consumption, the high rates and amounts of fish consumed by this population are relevant to evaluating risks of mercury contamination for communities with limited food resources.

The majority of vegetative desiccation-tolerant plants are found in the less complex clades that constitute the algae, lichens and bryophytes. However, within the larger and more complex groups of vascular land plants there are some 60 to 70 species of ferns and fern allies, and approximately 60 species of angiosperms that exhibit some degree of vegetative desiccation tolerance. In this report we analyze the evidence for the differing mechanisms of desiccation tolerance in different plants, including differences in cellular protection and cellular repair, and couple this evidence with a phylogenetic framework to generate a working hypothesis as to the evolution of desiccation tolerance in land plants. We hypothesize that the initial evolution of vegetative desiccation tolerance was a crucial step in the colonization of the land by primitive plants from an origin in fresh water. The primitive mechanism of tolerance probably involved constitutive cellular protection coupled with active cellular repair, similar to that described for modern-day desiccation-tolerant bryophytes. As plant species evolved, vegetative desiccation tolerance was lost as increased growth rates, structural and morphological complexity, and mechanisms that conserve water within the plant and maintain efficient carbon fixation were selected for. Genes that had evolved for cellular protection and repair were, in all likelihood, recruited for different but related processes such as response to water stress and the desiccation tolerance of reproductive propagules. We thus hypothesize that the mechanism of desiccation tolerance exhibited in seeds, a developmentally induced cellular protection system, evolved from the primitive form of vegetative desiccation tolerance. Once established in seeds, this system became available for induction in vegetative tissues by environmental cues related to drying. The more recent, modified vegetative desiccation tolerance mechanism in angiosperms evolved from that programmed into seed development as species spread into very arid environments. Most recently, certain desiccation-tolerant monocots evolved the strategy of poikilochlorophylly to survive and compete in marginal habitats with variability in water availability.

Isolates of P. infestans were obtained from infected tissue of tomato and potato collected from two areas: (i) where both potatoes and tomatoes are grown, and (ii) where only tomatoes are grown. The isolates were characterized by mating type, allozymes at the glucose-6-phosphate isomerase and peptidase loci, restriction fragment length polymorphism (RFLP) fingerprint with probe RG57, metalaxyl sensitivity, and aggressiveness to tomato and potato. The results suggest presence of an asexual population with frequent immigrations from outside the valley. There was a shift of mating type in the population from predominantly A2 to completely A1 in this period. The co-occurrence of mating types was restricted to very few fields in the area around Los Mochis where tomato and potato crops are grown. Genotype variation based on allozyme analysis and mating type was low with only one genotype affecting both crops each year. The genotypes affecting both crops were the only genotypes highly aggressive to both tomato and potato in laboratory aggressiveness tests and the only genotypes widespread on both the tomato and potato crops in the valley each year. These predominant genotypes were highly resistant to the fungicide metalaxyl. Data on metalaxyl sensitivity indicate that allozyme analysis can discriminate between sensitive and resistant isolates in the Del Fuerte Valley. RFLP analysis with the probe RG57 gives further discrimination of genotypes within an allozyme genotype. In the 1995 to 1996 season, four different RFLP genotypes were found within an allozyme genotype. However, there were five other dilocus allozyme genotypes that could not be further split by RFLP analysis in 1995 to 1996 and 1996 to 1997 seasons. Spatial analysis of genotypes suggests that each season individual fields near Los Mochis became infected with one or more genotypes, but only a single genotype, aggressive on both potato and tomato, occurred south and east to the Guasave area.

However, the diversity of weeds, crops and insect and fungal vectors also provide favorable conditions for plant virus disease development. This paper considers the incidence and management of several plant viruses that have caused serious epidemics and been significant in the agricultural development of the Salinas Valley during the 20th century. Beet curly top virus (BCTV) almost destroyed the newly established sugarbeet industry soon after its establishment in the 1870s. A combination of resistant varieties, cultural management of beet crops to provide early plant emergence and development, and a highly coordinated beet leafhopper vector scouting and spray programme have achieved adequate control of BCTV. These programmes were first developed by the USDA and still operate. Lettuce mosaic virus was first recognized as causing a serious disease of lettuce crops in the 1930s. The virus is still a threat but it is controlled by a lettuce-free period in December and a seed certification programme that allows only seed lots with less than one infected seed in 30000 to be grown. 'Virus Yellows' is a term used to describe a complex of yellows inducing viruses which affect mainly sugarbeet and lettuce. These viruses include Beet yellows virus and Beet western yellows virus. During the 1950s, the complex caused significant yield losses to susceptible crops in the Salinas Valley. A beet-free period was introduced and is still used for control. The fungus-borne rhizomania disease of sugarbeet caused by Beet necrotic yellow vein virus was first detected in Salinas Valley in 1983. Assumed to have been introduced from Europe, this virus has now become widespread in California wherever beets are grown and crop losses can be as high as 100%. Movement of infested soil and beets accounts for its spread throughout the beet-growing regions of the United States. Control of rhizomania involves several cultural practices, but the use of resistant varieties is the most effective and is necessary where soils are infested. Rhizomania-resistant varieties are now available that perform almost as well as the non-resistant varieties under non-rhizomania conditions. Another soil-borne disease termed lettuce dieback, caused by a tomato bushy stunt-like tombusvirus, has become economically limiting to romaine and leaf lettuce varieties. The virus has no known vector and it seems to be moved through infested soil and water. Heavy rains in the past 4 years have caused flooding of the Salinas River and lettuce fields along the river have been affected severely by dieback. Studies are now in progress to characterize this new virus and identify sources of resistance. Agriculture in the Salinas Valley continues to grow and diversify, driven by demands for 'clean', high quality food by the American public and for export. The major aspects of plant virus control, including crop-free periods, breeding for resistance, elimination of inoculum sources, and vector control will continue to be vital to this expansion. Undoubtedly, the advances in crop production through genetic manipulation and advances in pest management through biological control will eventually become an important part of agricultural improvement.

International and national development of criteria and indicators for maintenance of soil productivity make it imperative to have adequate threshold variables within the USDA Forest Service. In the Pacific Northwest, soils range from fine-textured Andisols to coarse-textured skeletal Inceptisols. Forest types encompass the highly productive coastal rain forest to marginally productive, dry, cold sites in the interior mountains. Constant values to detect detrimental disturbances within the soil quality guidelines are routinely applied across diverse soils and timber types and include diagnostic criteria for evaluating management-caused changes to soil productivity. Research information from short- or long-term research studies supporting the applicability of disturbance criteria is often lacking, or is available from a limited number of sites which have relatively narrow climatic and soil ranges. In this paper we calculated changes in soil carbon, nitrogen, erosion, and cation exchange capacity using threshold variables from the Regional USDA Forest Service Soil Guidelines to assess their applicability across diverse landscapes. Soils were selected from a climatic and elevational gradient in the Pacific Northwest. Application of selected USDA Forest Service standards indicate that blanket threshold variables applied over disparate soils do not adequately account for nutrient distribution within the profile or forest floor depth. These types of guidelines should be continually refined to reflect pre-disturbance conditions and site-specific information.

Murr. Var. shastensis) barrens located in McDonald basin on the north side of the Siskiyou Mountains crest is a major contributor of sediment to the aquatic system. Soil erosion is accelerated where vegetation is sparse and colonization slow, therefore, it is important that native plant cover be restored and the site rehabilitated. We examined soil properties that may be associated with vegetation patterns in the barrens and adjacent Shasta red fir forest and would have application to restoring native plant diversity and cover to the barrens. At a 40 ha study area we investigated plant available nutrients, soil C, microbial biomass, and enzymes involved in organic matter decomposition and nutrient cycling in barrens and forest soils to determine if loss of the organic layer by erosion affected soil chemistry and microbiology. Twelve samples each were collected from 0 to 10 cm soil depth in forest and barrens and analyzed for C, N, P, K, Ca, Mg, Mn, Fe, Cu, B, Zn, Mo, and Al; microbial biomass, and dehydrogenase, urease, and acid phosphatase activity. Soils supporting forest vegetation contained higher concentrations of C, N, K, Ca, and Mg, indicating differences between forest and barrens in important soil chemical properties. Ca and Mg were extremely low in the barrens soil suggesting loss of these nutrients by erosion where there is a lack of vegetation cover. Soil organic matter was higher in forest than in barrens soil and was positively correlated with soil N (r super(2)=0.78), dehydrogenase (r super(2)=0.65) and acid phosphatase activity (r super(2)=0.50). Although microbial biomass was extremely low, dehydrogenase and acid phosphatase activity were sensitive indicators of differences in organic matter and microbial activity between forest and barrens soil. The study indicates that certain soil chemical and biological properties may be useful in monitoring ecological change and helpful in understanding vegetation patterns.

Many studies have documented accelerated base cation losses with intensive forest harvesting. Acidic deposition can also alter nutrient cycling in these forests. The combination of increased harvesting, shorter rotations, and more intensive harvesting, along with the potential for N and S saturation due to changing atmospheric chemistry in the eastern US, raises concerns about the long-term productivity of these commercially important eastern hardwood forests. We review the literature describing the effects of intensive harvesting and acidic atmospheric deposition on budgets of base nutrients which presents evidence that the ambient levels of N and S deposition are leading to N and S saturation and elevated base leaching from the soil in some eastern forests, and we discuss potential concerns for long-term productivity. We also discuss criteria and indicators for monitoring sustainability of the soils of these forests.

Numerous granulocytes (PMNs) are evident in cecal tissue sections 24-48 h post-infection. The role of PMNs was assessed by utilizing monoclonal antibodies specific for CD18 or CD29 to block PMN recruitment. Macroscopic lesions were less severe in mice treated with either monoclonal antibody compared to lesions observed in isotype control-treated mice. While these monoclonal antibodies may inhibit extravasation of other leukocytes, the central role of PMNs was further demonstrated in that colitis was reduced following neutrophil depletion. There was less edema and epithelial erosions in ceca of mice receiving anti-Ly6G, -CD18 or -CD29 monoclonal antibody compared to mice receiving the control. Moreover, there was a significant reduction in PMN infiltration in tissues of mice treated with anti-CD18. The reduction in infiltrating PMNs did not result from downregulation of neutrophil chemoattractant MIP-2 expression in anti-CD18-treated mice. In contrast, PMN recruitment into the cecum was apparently CD29-independent. It is noteworthy that the number of PMNs observed in anti-CD18-treated mice was significantly higher than observed in non-infected mice. The data provide evidence for a threshold number of PMNs necessary for lesion development and indicate that CD18, but not CD29, adhesive pathways are crucial for PMN recruitment in bacterial colitis.

We extend previous analyses by distinguishing renters according to lease type and by distinguishing practices according to the timing of costs and returns. We find that cash-renters are less likely than owner-operators to use conservation tillage, but share-renters are not. Both cash-renters and share-renters are less likely than owner-operators to adopt practices that provide benefits only over the longer term (grassed waterways, stripcropping, and contour farming).

International donor agencies, such as the World Bank and the US Agency for International Development, are especially interested in public/private partnerships to develop and integrate information including the socio-economic/cultural contexts of farm systems to improve knowledge about food systems, nationally to globally. The International Agricultural Research Centers, non-government organizations and national institutions require a spatial-temporal-hierarchical information system describing farm systems and communities from the `nation to the farm'. Agri-business requires methods to evaluate the performance of crop systems in varied environments in countries and/or around the world. As the society is stratified by different information needs, decisions must be made about the units of study and the hierarchy of information integration. The proposed hierarchy, developed on the tenets of hierarchy theory, implies that optimization of biodiversity, ecosystem health and integrity, commodity production, or maintaining soil quality, are each articulated based on the objectives that apply to the planning area. Management goals, therefore, determine the planning area to be defined, the goods and services, and the desired conditions of the ecosystem. Defined biophysical units, such as resource management domains (RMDs), serve as a common denominator for synthesis of information which could be shared by a range of disciplines, such as hydrology, geomorphology, pedology, crop science, economics, sociology, land-use planning, and production technology. In this approach, system dynamics or temporal variations are de-emphasized with the assumption that each RMD has attained an equilibrium or quasi-equilibrium within the planning horizon of the society. This is due to the practical purpose for which land resource assessments are generally made. However, if time periods of 50 or more years are considered, the concept must be refined. The latter approach is required for assessments of forest ecosystems.

Infection of cattle with M. bovis stimulates an antigen-specific T-cell response, with both CD4 super(+) and CD8 super(+) cells implicated in protective immunity. Few studies, however, have examined lymphocyte subset responses to experimental M. bovis infection of white-tailed deer. In this study, a flow cytometric proliferation assay was used to determine the relative contribution of individual peripheral blood mononuclear cell subsets of M. bovis-infected white-tailed deer in the recall response to M. bovis antigen. Naive deer were challenged with M. bovis by cohabitation with infected deer. These M. bovis-challenged deer developed significant in vivo (delayed-type hypersensitivity) and in vitro (proliferative) responses to M. bovis purified protein derivative (PPD). At necropsy, typical tuberculous lesions containing M. bovis were detected within lungs and lung-associated lymph nodes of infected deer. The predominant subset of lymphocytes that proliferated in response to in vitro stimulation with PPD was the CD4 super(+) subset. Minimal proliferative responses were detected from CD8 super(+), gamma delta TCR super(+), and B-cells. Addition of monoclonal antibodies specific for MHC II antigens, but not MHC I or CD1 antigens, abrogated the proliferative response. Together, these findings indicate that while CD4 super(+) cells from infected deer proliferate in the recall response to M. bovis antigens, this response is not sufficient to clear M. bovis and immunologic intervention may require stimulation of alternate subsets of lymphocytes.

In this study, a water balance was computed using 10 years of data collected at the Upper Sheep Creek Watershed, a 26-ha semi-arid mountainous sub-basin within the Reynolds Creek Experimental Watershed in southwest Idaho, USA. The approach computed a partial water balance for each of three landscape units and then computed an aggregated water balance for the watershed. Runoff and change in ground water storage were not distinguishable between landscape units. Precipitation, which occurs predominantly as snow, was measured within each landscape unit directly and adjusted for drifting. Spatial variability of effective precipitation was shown to be greater during years with higher precipitation. Evapotranspiration, which accounted for nearly 90% of the effective precipitation, was estimated using the Simultaneous Heat and Water (SHAW) Model and validated with measurements from Bowen ratio instruments. Runoff from the watershed was correlated to precipitation above a critical threshold of approximately 450 mm of precipitation necessary to generate runoff (r super(2) = 0.52). The average water balance error was 46 mm, or approximately 10% of the estimated effective precipitation for the ten-year period. The error was largely attributed to deep percolation losses through fractures in the basalt underlying the watershed. Simulated percolation of the water beyond the root zone correlated extremely well with measured runoff (r super(2) = 0.90), which is derived almost entirely from subsurface flow. Above a threshold of 50 mm, approximately 67% of the water percolating beyond the root zone produces runoff. The remainder was assumed to be lost to deep percolation through the basalt. This can have important ramifications in addressing subsurface flow and losses when applying a snowmelt runoff model to simulate runoff and hydrologic processes in the watershed.

Thirty five calves were utilized in this study. Calves in Group 1 (n = 7) did not receive any H. somnus vaccination and served as negative controls. Calves in each of Groups 2-5 (n = 7 each) were vaccinated on days 0 (primary) and 14 (booster) with one of four commercially available H. somnus bacterins. Sera were harvested on days 0 and 14 and at weekly intervals for a total of 45 days. Sera were tested for the presence of IgE antibodies using a bovine IgE-specific ELISA. Low levels of H. somnus-specific IgE were detected by ELISA in all animals prior to the initiation of the study. All bacterins induced IgE levels that were significantly higher than control levels. Two bacterins elicited higher IgE levels at all time points. Sera were adsorbed against washed whole cells of either Salmonella typhimurium, P. multocida, or H. somnus or extracts of H. somnus. ELISA absorbance values were significantly decreased by adsorption with washed whole cells or extracts of H. somnus, whereas adsorption with other gram-negative bacteria only minimally decreased ELISA absorbance values. These results indicate that commercially available H. somnus bacterins can induce IgE antibody as early as 14 days post-vaccination. This IgE can be detected 45 days after the primary vaccination. Results also indicate that H. somnus-specific IgE antibodies can be found in serum of some cattle, possibly induced by existing or previous sensitization.

In this study, rabbit antisera were raised against a recombinant protein of HspX fused to the Escherichia coli maltose binding protein (MBP/HspX). Immunoblots of lysates of M. paratuberculosis-infected macrophages probed with the rabbit antisera showed that HspX was present within infected macrophages of bovine and murine origin. This observation was confirmed by immunofluorescence microscopy of infected macrophages. Lysates of E. coli expressing HspX without the MBP fusion partner were loaded onto preparative SDS-PAGE gels and used to determine whether infected cattle generated a humoral immune response to the antigen. Sera from four of 24 paratuberculous cows (17%) detected HspX. No reactivity was present in sera from control cows. While HspX may be immunogenic during infection in some cows, the protein is not secreted and it does not stimulate cell-mediated immunity. Collectively, these data give a preliminary characterization of the first described M. paratuberculosis protein identified within infected macrophages.

Trees thinned from plot buffer zones at age 38 were selected to represent a final harvest cross-section of each treatment for evaluation of bole form, component biomass, and crown architecture. Volume and biomass of cut trees from all thinnings were included with the age 38 data for stand level yield comparisons. Results show thinning effects were generally more pronounced than spacing effects. Trees of the same diameter at breast height and total height from heavily thinned stands had more cylindrical lower boles, more upper stem taper, longer crowns with more and larger branches, more total foliage, and hence more biomass than trees from unthinned or lightly thinned stands. All levels of thinning increased the yield of the stand in terms of foliage and branch biomass, while only light or moderate thinning increased bole biomass and volume yields. The magnitude of these differences are presented.

All applications successfully reduced competition from oaks in the overstory and understory (mortality >80%), resulting in progressive increases in the foliar cover of wiregrass, all graminoids and forbs through time. Broadcast application caused a decline in forb cover and species richness during the initial growing season, which recovered by the following year. The 2.2 kg/ha spot application resulted in an increase in species richness, while evenness declined with the continuing expansion of wiregrass. The entire site was then burned in June 1995 by prescribed fire, which caused a widespread decrease in the cover of oaks, shrubs, wiregrass, all graminoids and forbs and plant species richness. In the following year, forb cover increased and oak cover remained significantly lower on plots treated with the combination of hexazinone plus fire than on fire-only plots. The overall cover of forbs, graminoids, shrubs and longleaf pines continued to increase through time. Broadcast application initially exposed a greater number of understory plants to direct contact with herbicide, posing a higher mortality risk than may be acceptable in restoration efforts. Although recovery occurred in subsequent years, the lower selectivity of broadcast application makes it a less suitable restoration technique. Spot application of hexazinone was more selective in its effects upon the plant community. The 2.2 kg/ha spot application produced increases in the cover of wiregrass, all graminoids and forbs and the highest levels of species richness and diversity. The 2.2 kg/ha application rate was also most effective in controlling woody plant competition and is therefore recommended for restoring longleaf pine wiregrass ecosystems in sandhills and similar environments. Hexazinone application followed by prescribed fire accelerates the rate of ecosystem restoration over that achievable by using fire alone. The ecological benefits of controlling competition and rebalancing floristic composition rapidly achieved through this combination of treatments would likely require many cycles of prescribed fire, if used as an individual treatment, over a period of several decades.

Cultures that were provided with ball-milled cellulose initially produced fermentation acids and microbial protein as fast as those provided with cellobiose, but the absolute cellulose digestion rate eventually declined. If the inoculum size was increased, the kinetics decayed from first to zero order (with respect to cells) even sooner, but in each case the absolute rate declined after only 20 to 30% of the cellulose had been fermented. Congo red binding indicated that the cellulose surface area of individual cellulose particles was not decreasing, and the transition of ball-milled cellulose digestion corresponded with the appearance of unbound cells in the culture supernatant. When bound cells from partially digested cellulose were removed and the cellulose was re-incubated with a fresh inoculum, the initial absolute fermentation rate was as high as the one observed for undigested cellulose and cellobiose. Based on these results, cellulose digestion by F. succinogenes S85 appears to be constrained by cellulose surface area rather than cellulase activity per se.

Inoculation of eyes did not result in mortality or disease signs in either species. In contrast, mortality and disease signs were observed in both species following nares inoculation. Hybrid striped bass were susceptible to 4.8 x 10 super(3) S. iniae colony forming units (CFU), an inoculum 100 times lower than that affecting tilapia. We observed decreased mortality of hybrid striped bass administrated 4.8 x 10 super(5) CFU dose of S. iniae. Following S. iniae infection, the disease signs observed in hybrid striped bass and tilapia were erratic, serpentine, rising and falling, and head-up swimming, slow acceptance or refusal of food, lethargy and darkened skin. We did not observe exophthalmia, eye opacity or body curvature. We were able to recover S. iniae from either nares, eyes, brains, or head kidney of 87.5% and 66.7% of the morbid hybrid striped bass and tilapia, respectively. Both hybrid striped bass and tilapia produced significant anti-streptococcal titers 14 days post nares inoculation with 4.8 x 10 super(3) CFU of S. iniae. Successful experimental S. inaie infection of fish following nares inoculation suggest that nares may be a potential route of S. iniae infection in cultured fish species. This route of experimental infection for S. iniae has not been previously described in fish.

Further blending of starch-glycerol with polyvinyl alcohol (PVOH) resulted in significant improvements in both tensile strength (TS) and elongation at break. Samples of starch-glycerol without PVOH equilibrated at 50% relative humidity had a TS of 1.8 MPa and elongation of 113%, whereas those containing PVOH had a TS and elongation of 4 MPa and 150%, respectively. Dynamic mechanical analysis (DMA) of starch-glycerol-PVOH blends showed that decreases in glass transition temperatures (T sub(g) values) were proportional to glycerol content. Scanning electron microscopy (SEM) of fractured surfaces revealed numerous cracks in starch-glycerol (80:20) samples. Cracks were absent in starch-glycerol (70:30) samples. In both blends, many starch granules were exposed at the surface. No exposed starch granules were visible in blends with added PVOH. Starch-glycerol samples incubated in compost lost up to 70% of their dry weight within 22 days. Addition of PVOH lowered both the rate and extent of biodegradation.

AN - 72378342; 11057724 AB - Colonies of Reticulitermes spp. were baited with prototype and commercial Sentricon stations (Dow AgroSciences LLC, Indianapolis, IN) to test the efficacy of hexaflumuron in different concentrations and bait matrices and to document reinvasion of the foraging territories vacated by eliminated colonies. Seven colonies of Reticuliternes spp. from two sites were characterized with cuticular hydrocarbon analyses and mark-release-recapture and agonistic behavioral studies. Three colonies were observed as controls and four colonies were baited. When a connection between the bait station and the monitoring station could not be confirmed by mark-release-recapture studies, the results of the baiting were equivocal. The monitoring stations of a colony at our wildland site were devoid of termites 406 d after baiting with one Sentricon station, but became reoccupied with the same species of termites approximately 6 mo after baiting. A colony at the residential site was baited with 0.5% hexaflumuron in the Recurit II bait matrix; 60 d later termites were absent from all monitoring stations. These monitoring stations remained unoccupied for > or = 18 mo. Foraging Reticulitermes spp. appeared in three of the seven monitoring stations 18, 24, and 36 mo after baiting, respectively. Using cuticular hydrocarbon analyses and agonistic behavior studies, we determined that the Reticulitermes spp. occupying these monitoring stations were from three different colonies; none were members of the original colony destroyed by baiting. Another colony at the residential site was baited using a noncommercial, experimental bait; 52 d later termites were absent from all monitoring stations. The monitoring stations remained unoccupied for > or = 9 mo. A different Reticulitermes sp. colony invaded one monitoring station 9 mo after baiting.

AN - 72376162; 11057728 AB - Stored-product insects are a perennial problem in retail stores, where they damage and contaminate susceptible merchandise such as food products and animal feed. Historically, pest management in these stores has relied heavily on chemical insecticides, but environmental and health issues have dictated use of safer methods, and these require better monitoring. A monitoring procedure that employs an array of moth and beetle traps combined with spatial (contour) analysis of trap catch was tested in three department stores and two pet stores. The rate of capture increased with the level of infestation but was essentially constant over 4- to 5-d trapping periods. Contour analysis effectively located foci of infestation and reflected population changes produced by applications of the insect growth regulator (S)-hydroprene. The most abundant insects were Plodia interpunctella (Hiibner), Lasioderma serricorne (F.), Oryzaephilus mercator (Fauvel), Tribolium castaneum (Herbst), and Cryptolestes pusillus (Schönherr). The results indicate that contour analysis of trap counts provides a useful monitoring tool for management of storage pests in retail stores. It identifies trouble spots and permits selection, timing, and precision targeting of control measures to achieve maximum pest suppression with minimum pesticide risk. It permits managers and pest control operators to visualize pest problems over an entire store, to monitor changes over time, and to evaluate the effectiveness of control intervention. The contour maps themselves, along with records of control applications and stock rotation, provide permanent documentation of pest problems and the effectiveness of pest management procedures.

(insecta, coleoptera, silvanidae). AN - 72373541; 11052767 AB - Esterases from a fenitrothion-resistant strain (VOSF) of the saw-toothed grain beetle, Oryzaephilus surinamensis (L.), are presumed to play a role in conferring resistance to malathion, fenitrothion, and chlorpyrifos-methyl. Colorimetric assays showed a significant positive correlation between increased resistance to fenitrothion in strains of O. surinamensis examined and elevated esterase hydrolytic activity to substrates of p-nitrophenyl acetate, alpha-naphthyl acetate, and beta-naphthyl acetate. Esterase zymograms showed different banding patterns between VOSF and an insecticide-susceptible strain, VOS48. A major esterase in the VOSF strain, not detected in VOS48, was purified and characterized by chromatographic and electrophoretic techniques. On the basis of SDS-polyacrylamide gel eletrophoresis, the molecular mass of the purified esterase from VOSF was 130 kDa and consisted of two 65 kDa subunits.

AN - 72368571; 11052693 AB - Larkspur (Delphinium spp.) poisons thousands of cattle on western rangelands each year. Because poisoning does not cause specific lesions, and poisoned animals are rarely found before they die, definitively identifying poisoned animals is difficult. Additionally, toxin concentrations in larkspur plants vary with environment, plant, and location. Rapid, sensitive, and specific diagnostic techniques are needed to identify poisoned animals and to determine when and what plants are likely to poison livestock. In this study, three competitive inhibition enzyme-linked immunosorbent assays (CI-ELISA) for toxic larkspur alkaloids were developed. One assay is class-specific toward the N-(methylsuccinimido)anthranoyllycoctonine (MSAL) alkaloids, and two assays are specific for individual alkaloids. The assay with the lowest limit of detection had an I(50) of 191 pg with a limit of detection of 30.5 pg for methyllycaconitine. Spike and recovery studies using bovine blood and brain tissue ranged from 52 to 89%. These findings suggest that with additional development these techniques are likely to be excellent tools for diagnosing poisoned animals and identifying highly toxic plants.

AN - 72368241; 11052722 AB - De-esterification is an initial step in the metabolism of certain herbicides, for example, fenoxaprop-ethyl [(+/-)-ethyl 2-[4-[(6-chloro-2-benzoxaolyl)oxy]phenoxy]propanoate] (FE). The ethyl-ester bond cleavage of FE to fenoxaprop acid (FA) by purified enzymes, crude bacterial enzyme preparations, and soils was investigated. In similar experiments fluorescein diacetate (FDA) was used as an alternative substrate. FE stability was pH sensitive in acidic buffered solutions; that is, below pH 4.6, rapid nonenzymatic hydrolysis of the benzoxazolyl-oxy-phenoxy ether linkage occurred, forming 6-chloro-2,3-dihydro-benzoxazol-2-one (CDHB) and ethyl 4-hydroxyphenoxypropanoate or 4-hydroxyphenoxypropanoate. With porcine esterase and cell-free Pseudomonas fluorescens extracts, activity on FE and FDA was most rapid at pH 7.6-8.6 but decreased 80-90% at pH 5.6. Yeast (Candida cylindrica) lipase-mediated de-esterification of FE and FDA was not as sensitive to pH; that is, activity at pH 4.6 was 70% of that at pH 7.6. Short-term incubations (20 h) were conducted in eight soils (pH 4.5-6.9) treated with (14)C-chlorophenyl ring-labeled FE (2 mg kg(-)(1)). In the most acidic soils (pH 4.4-4.5) 25% of the (14)C was recovered as FA, versus 30-40% in moderately acid soils (pH 5.0-5.6) and 55% in neutral soils (pH 6.8-6.9). There was a similar correlation between soil pH and FDA de-esterification. CDHB was formed in all acidic soils with levels 4-fold greater in pH 4.4-4.5 soils than in pH 5. 0-5.6 soils. CDHB was not formed in neutral soils. Results demonstrate some chemical hydrolysis (benzoxazolyl-oxy-phenoxy ether linkage) of FE in acid soils, the sensitivity of enzymatic de-esterification of FE to pH, and the potential of FDA as a colorimetric indicator for esterase hydrolysis of FE.

AN - 72329067; 11028959 AB - Using available data on the occurrence of Salmonella enteritidis (SE) in US layer flocks and eggs, and a probabilistic scenario tree method, an estimate of the fraction of SE-contaminated eggs produced annually is derived with attendant uncertainty. In lieu of a definitive prevalence survey, the approach presented here provides insight to the relative contribution of various pathways leading to contaminated eggs. A Monte Carlo model with four branches is developed. The first branch predicts the proportion of all US flocks that are SE-affected. The second branch apportions SE-affected flocks into three categories (high, moderate, and low level affected flocks) based on population-adjusted epidemiologic data. The third branch predicts the proportion of affected flocks that are molted and producing eggs during a high risk period subsequent to molt. The fourth branch predicts the fraction of contaminated eggs produced by flocks of the type described by the pathway (e.g. high level affected flocks that are not molted) based on egg sampling evidence from naturally infected flocks. The model is simulated to account for uncertainty in the data used to estimate the branch probabilities. Correlation analysis is used to estimate the sensitivity of model output to various model inputs. The output of this model is an uncertainty distribution for the fraction of all eggs that are SE-contaminated during 1 year of production in the US. The expected value of this distribution is approximately one SE-affected egg in every 20,000 eggs annually produced, and the 90% certainty interval is between one SE-contaminated egg in 30,000 eggs, and one SE-contaminated egg in 12,000 eggs. The model estimates that an average of 14% of all eggs (i.e. contaminated and not contaminated) from affected flocks are produced by high level, non-molted affected flocks, but these flocks are estimated to account for more than two-thirds of the total fraction of contaminated eggs produced annually. Sensitivity analysis also suggests that the proportion of affected flocks that are high level flocks - and the egg contamination frequency for these types of flocks - are the most sensitive model inputs. The model's pathways provide a framework for evaluating interventions to reduce the number of contaminated eggs produced in the US. Furthermore, sensitivity analysis of the model identifies those inputs whose uncertainty is most influential on the model's output. Future farm-level research priorities can be established on the basis of this analysis, but public policy decisions require a fuller exposure assessment and dose-response analysis to account for microbial growth dynamics, meal preparation, and consumption demographics among US egg consumers.

AN - 72319611; 11023699 AB - A field survey was conducted in 1989, 1994, and 1999 in order to monitor the soil and vegetation Se concentrations at the Kesterson upland grassland contaminated by Se-rich drainage sediment. The rate of Se dissipation estimated by the change of soil Se concentration, via volatilization, found to be about 1.1% per year. Soil water-extractable Se increased in 1994, but greatly reduced in 1999. The increase of soil Se concentration in the top 15 cm of soil at the fresh-soil fill sites indicates that the plants were able to effectively take up the soluble soil Se from the lower soil profile and to deposit it on the top of the field. This process may reduce the rate of leaching of soil Se. Overall, the concentration of soil water-soluble Se was relatively low and it is unlikely that problems of transport of Se from the Kesterson soil to the adjacent uncontaminated environment by leaching can occur. Plant tissue Se concentration was found to coincide with the soil water-extractable Se concentration. The average plant tissue Se concentration and soil water-extractable Se detected in 1999 was about 10 microg Se g(-1) and 110 microg Se kg(-1) dry weight, respectively, and the estimated bioaccumulation value of this upland grassland is less than 10% of the previous wetland habitat. Therefore, the existing Kesterson grassland should not be at high risk to the environment. Copyright 2000 Academic Press.

AN - 72308973; 11021413 AB - Commercially available infant formulas serve as the best alternative to human milk when breastfeeding is not possible. Infant formulas are designed specifically to mimic the composition of human milk or the functional aspects of human milk feeding. This review highlights the issues related to the composition of infant formulas. The most hotly debated issue currently is whether to add long-chain polyunsaturated fatty acids to infant formulas. Other controversial topics include the safety and efficacy of soy-based protein formulas, protein quantity and quality as they relate to the infant's nutritional needs and feeding tolerance, and the replacement of lactose with other carbohydrate sources for specialized infant formulas. Recent modifications in the fat blend of infant formulas have led to improved fat digestibility. However, the full spectrum of benefits associated with the addition of nucleotides awaits further study. Modifications to infant formulas are made when the preponderance of scientific evidence suggests that the compositional change will better meet the nutritional needs of the infant.

In this study, CCA-treated wood wafers were treated with a two-step remediation process to remove copper, chromium and arsenic. Process conditions, involving an acid extraction and bacterial culture with a metal-tolerant bacterium, were optimized. It was determined that 18 h of exposure to 1.0% oxalic acid was an optimal exposure time for the size of wood used in this study. Oxalic acid concentration was then varied to determine optimal concentration for metal removal. Increasing concentrations of oxalic acid removed increasing quantities of copper, chromium and arsenic. Acid extraction at 0.80% and bacterium exposure resulted in a total reduction of 78% copper, 97% chromium and 93% arsenic. An 0.8% of oxalic acid followed by bacterial culture with Bacillus licheniformis CC01 afforded the best conditions for maximum removal of copper, chromium, and arsenic from treated wood with minimal exposure of the wood fiber to acid conditions.

Studies focused on spermatozoa tolerance to the following: 1) osmotic stress, 2) different extracellular concentrations of the cryoprotectant dimethylacetamide (DMA), 3) equilibration times of 1 versus 4 h, 4) equilibration temperature of 4 versus 21 degree C, and 5) rapid versus slow cooling before cryopreservation and standard thawing. Sperm viability was assessed with the live/dead stain (SYBR-14/propidium iodine). Sperm viability at osmolalities greater than or equal to 800 mOsm was higher (P < 0.05) in raptor than poultry semen. Return to isotonicity after exposure to hypertonicity (3000 mOsm) decreased (P < 0.05) number of viable spermatozoa in chicken, turkey, and golden and Bonelli's eagle spermatozoa but not in imperial eagle or peregrine falcon spermatozoa. Differences were found in spermatozoa resistance to hypotonic conditions, with eagle species demonstrating the most tolerance. Semen, equilibrated for 1 h (4 degree C) in diluent containing DMA ( greater than or equal to 2.06 M), experienced decreased (P < 0.05) spermatozoa survival in all species, except the golden eagle and peregrine falcon. Number of surviving spermatozoa diminished progressively with increasing DMA concentrations in all species. Increased equilibration temperature (from 4 to 21 degree C) markedly reduced (P < 0.05) spermatozoa survival in all species except the Bonelli's eagle and turkey. Rapid cooling was detrimental (P < 0.05) to spermatozoa from all species except the imperial eagle and the chicken. These results demonstrate that avian spermatozoa differ remarkably in response to osmotic changes, DMA concentrations, equilibration time, temperature, and survival after fast or slow freezing. These differences emphasize the need for species-specific studies in the development and enhancement of assisted breeding for poultry and endangered species.

In these studies we examined the effects of media phenols, thiols, and metals on endothelial cell-mediated oxidation. We found that cell culture media such as Dulbecco modified Eagle medium and minimal essential medium are unable to support cell-mediated oxidation of LDL because they contain high concentrations of phenol red (PR) and tyrosine, both of which strongly inhibit cell-mediated oxidation. Ham's F-10, a commonly used medium for cell-mediated oxidation experiments, is also not entirely appropriate, as it contains both PR and cysteine. Cysteine is not critical for endothelial cell-mediated oxidation, but does increase oxidation of LDL in the absence of cells. Finally, of utmost importance to cell-mediated oxidation was the presence of either micromolar concentrations of Fe(II) or physiological concentrations of holo-ceruloplasmin, the protein which carries copper in plasma. An appropriate culture medium for use in cell-mediated oxidation experiments should thus contain either micromolar concentrations of Fe(II) or physiological concentrations of holo-ceruloplasmin, and should be prepared without PR, cysteine, or large concentrations of tyrosine, all of which are shown here to inhibit endothelial cell-mediated LDL oxidation. These results are consistent with a mechanism of cell-mediated oxidation involving Fenton-type chemistry and redox cycling of the metal.

The number of infected quarters, milk somatic cell counts, milk components, and intramammary infection were studied at weaning in 164 beef cows. The percentage of infected cows ranged from 61.9% at first parity to 66.7% at fifth to ninth parities. Cows with three or four infected quarters had higher (P .10) calf weaning weight. In conclusion, intramammary infection had no effect on calf weaning weight but increased milk somatic cell count and decreased the percentage of protein, lactose, solids-not-fat, and butterfat. The number of infected and blind mammary quarters increased with parity. Implications: Results indicate that 66% of beef cows on pasture have subclinical mastitis, and 15% of all mammary quarters for cows with five to nine parities are infected with Staphylococcus aureus. For beef cows with fewer parities, only 1 to 4% of the quarters are infected. This organism is a serious mastitis pathogen that destroys mammary secretory tissue and causes decreased milk production. It is spread from cow to cow through the transfer of infected milk from one mammary quarter to another by suckling. Weaning weight of calves from cows with subclinical mastitis in four mammary quarters was 5 kg less than herd mates free from intramammary infection. A mastitis control program for beef cows may reduce incidence of mastitis and the spread of S. aureus and increase calf weaning weight.

RNA isolation and reverse-transcription (RT)-PCR protocols were developed as tools to detect gene expression in bacteria on beef carcass surfaces. The utility of these procedures was demonstrated by detecting the expression of a selectively-inducible green fluorescent protein (GFP) gene in a plasmid-transformed strain of Escherichia coli O157:H7 inoculated onto beef carcass surface tissue. These procedures should serve as useful tools for studying the genetic responses of bacteria when exposed to antimicrobial interventions applied to food animal carcasses.

Studies of the genetics of resistance to blight have generated inconsistent reports due to year to year and between location variation in screening trial results. Most previous studies have relied on F sub(2) or backcross populations for segregation analyses; however, inheritance patterns have been difficult to confirm because of the inability to repeat the evaluations in time and space. The objective of this study was to determine the inheritance of resistance to ascochyta blight in chickpea using recombinant inbred line (RIL) populations. The RILs were derived from two intraspecific crosses, PI 359075(1) x FLIP 84-92C(2), 'Blanco Lechoso' x 'Dwelley', and one interspecific cross, FLIP 84-92C(3) x C. reticulatum Lad. (PI 599072). The resistant parents, FLIP 84-92C and Dwelley, had a common source of resistance derived from ILC-72. Disease reactions of the parents and RILs were scored using a 1 to 9 scale and also by using the area under the disease progress curve (AUDPC). Segregation among RILs indicated that three recessive and complementary major genes with several modifiers conferred ascochyta blight resistance. Absence of one or two of the major genes confers susceptibility, whereas the presence of the modifiers determines the degree of resistance.

The objectives of this study were (i) to determine the inheritance of resistance to races 0 and 5 of fusarium wilt and the genetic map positions of the resistance genes and (ii) to assess the linkage relationships between these two genes and other known wilt resistance genes in chickpea. Seedlings of 131 F sub(6)-derived recombinant inbred lines (RILs) were tested for reaction to races 0 and 5. A 1 resistant: 1 susceptible segregation ratio was observed for both races, indicating that resistance to each race is controlled by a single gene. Linkage analysis indicated that the genes for resistance to races 4 and 5 were in the same linkage group and were separated by 11.2 centiMorgans (cM). The gene for resistance to race 0 was not linked to the race 4 and 5 resistance genes. In addition, an allele-specific associated primer (ASAP) product (CS-27R/CS-27F), developed from the CS-27 primer, was located between the two resistance genes and was 7.2 and 4 cM from the genes for resistance to races 4 and 5, respectively. Map positions of these two race-specific resistance genes and the marker reported to be linked to the genes for resistance to races 1 and 4 support the hypothesis that wilt resistance genes are clustered on the same chromosome. Since the gene conferring resistance to race 0 is found in a different region of the genome, other genomic regions may be responsible for resistance to wilt pathogens. The gene symbols foc-0, foc-4, and foc-5 are proposed for the genes for resistance to races 0, 4, and 5 of the pathogen, respectively. Identification and further evaluation of disease resistance gene clusters would improve our understanding of wilt resistance in chickpea and facilitate the transfer of resistance genes to new cultivars.

Because of its high volatility and toxicity, atmospheric emission of CP during soil application may become a source of air pollution. We investigated degradation of CP in three different soils as a function of soil temperature and moisture conditions, and evaluated its volatilization against methyl bromide (MeBr) from packed soil columns. Chloropicrin degraded much faster than MeBr in the same soil, mainly via microbial degradation. Degradation of CP accelerated as soil temperature increased, but was relatively independent of changes in soil moisture. When the soil surface was uncovered, overall volatilization loss of CP was similar to that of MeBr. Covering the soil surface with a polyethylene or high-barrier film was much more effective in reducing volatilization of CP than MeBr. Therefore, surface covers may be used in sensitive areas to reduce human exposure to CP.

Impairment of freshwater quality by accelerated eutrophication has focused attention on manure management and the potential for P loss in runoff. Thus, we investigated the amounts and relative solubilities of P in manures and their composts using a modified Hedley fractionation and release of P during simulated rainfall (70 mm h super(-1) for 30 min) in laboratory columns (15-cm diameter). Twenty-four samples each of dairy manure, dairy manure compost, poultry manure, poultry manure compost, poultry litter, and swine manure were collected over 2 yr. Total P concentration ranged from 2600 to 40 000 mg kg super(-1), mostly as inorganic P (63 to 92%). The distribution of inorganic and organic P fractions depended on manure and compost type. Most of the inorganic P, 80%, was water extractable (2030 mg kg super(-1)), while 55% was hydroxide extractable in swine slurry (16 620 mg kg super(-1)) and 38% acid extractable in poultry manure (9320 mg kg super(-1)). The dissolved inorganic P concentration in leachate from manure and compost (10 Mg ha super(-1) manure application rate) during a 30-min rainfall ranged from 34 (poultry litter) to 75 mg L super(-1) (poultry manure). The amount of P leached by five simulated rainfall events was significantly correlated to respective water extractable inorganic (r super(2) = 0.98) or organic P (r super(2) = 0.99) of each material. This suggests that water extractable P may be used to estimate the potential for land-applied manures or composts to enrich leachate and surface runoff P.

Soils contained 15 500 mg Zn and 158 mg Cd kg super(-1) and initial soil pH was 6.0. Zinc-resistant `Merlin' red fescue (Festuca rubra L.) was compared with `Bonanza' and `Kentucky-31' tall fescue (Festuca arundinacea Schreb.) and `Touchdown' Kentucky bluegrass (Poa pratensis L.) for leaf phytotoxicity symptoms, rapidity of achieving cover, persistence of cover, and metal accumulation. Biosolids compost more strongly reduced soluble Zn and Cd, resulting in effective remediation of Zn phytotoxicity that persisted for the 4 yr of this test. `Merlin' red fescue showed remarkable exclusion of Zn and Cd (201-446 mg kg super(-1) Zn and 0.9-2.7 mg kg super(-1) Cd in dry shoots from treated plots) but grew slowly and made poor lawns. `Kentucky-31' tall fescue plants grew rapidly and reached almost 100% cover within 3 mo in compost treatment plots, but the Zn exceeded phytotoxic threshold levels (>500 mg Zn kg super(-1)). `Bonanza' tall fescue and `Touchdown' Kentucky bluegrass had good growth performance and contained lower concentrations of Zn and Cd than `Kentucky-31' tall fescue on biosolids-compost amended treatments and were more suitable as a lawn and/ or revegetation crop. After the first year of the study, the commercial turfgrasses survived only on the biosolids-compost plots. The combination of calcareous soil pH and higher organic matter, Fe, and phosphate levels of biosolids-compost amended plots improved the overall success of vegetation establishment and allowed important turfgrasses to revegetate highly Zn-contaminated soils.

Application occurred from June through October at an average rate of 10 cm yr super(-1) from 1979 to 1982, 24 cm yr super(-1) from 1983 to 1988, and 40 cm yr super(-1) from 1989 to 1996, increasing surface flow from the application area by 47, 78, and 154%, respectively. The pH of the peatland outflow increased from 4.2 to 6.7, chloride rose from 1.1 mg L super(-1) to 80 mg L super(-1), and total phosphorus increased from 0.05 mg L super(-1) to 0.6 mg L super(-1). Because raw sewage input was only one-half of the lagoon system's design capacity, the lagoons provided a high degree of sewage treatment, removing 95% of suspended solids (SS), biochemical oxygen demand (BOD), and nitrogen from the wastewater stream. Phosphorus removal in the lagoons, which was 98% in the first years of operation, declined to 85% by 1995. The peatland contributed little additional treatment, removing only 37% of the nitrogen and 17% of the phosphorus remaining in the lagoon effluent. The peatland's capacity to retain phosphorus was exhausted after a few years of application. Increased pH, nutrient availability, and water levels altered the peatland vegetation community. The Sphagnum ground cover was reduced or eliminated in many places, and dense stands of cattail (Typha sp.) developed in some areas. Small peatlands such as this one seem poor candidates for use as tertiary treatment systems.

Diet of nestlings on or near an old-growth longleaf pine (Pinus palustris) remnant in southern Georgia was compared to that in longleaf pine stands established on old farm fields in western South Carolina. Diets of nestlings were expressed as percent nest visits and percent prey biomass. The method of calculating nestling diet composition had little effect on the relative ranking of prey. Roaches (Blattaria: Blatellidae) were the most common arthropod fed to nestlings, ranging from 33-57% of the prey brought to nest cavities by adults or 55-73% of the prey biomass. Other common prey were spiders, centipedes and caterpillars. The latter were primarily larvae of coneworms (Lepidoptera: Pyralidae, Dioryctria spp.) that bore into and feed on pine cones. Scorpions (Scorpiones: Buthidae, Centruroides sp.), an unusual prey, were recorded several times at the south Georgia location. Morisita's index (C) of diet overlap showed a high degree of similarity in nestling diets among years in the old-growth remnant (C = 0.91 to 0.94), as well as a high degree of similarity in the diets of nestlings among woodpecker groups within locations and between old-growth and old-field habitats (C = 0.89-0.95). Our study shows that old trees on relatively undisturbed sites provide the same prey as younger trees growing on old farm fields and the relative importance of the different prey was similar for both habitats.

This, in turn, will decrease the net emission of carbon dioxide. A number of studies exist that calibrate the contribution of various individual, site-specific conservation practices on changes in soil organic carbon. There is a general absence, however, of a comprehensive effort to measure objectively the contribution of these practices including conservation tillage, the Conservation Reserve Program, and conservation buffer strips to an change in soil organic carbon. This paper fills that void. After recounting the evolution of the use of the various conservation practices, it is estimated that organic carbon in the soil in 1998 in the United States attributable to these practices was about 12.2 million Mt. By 2008, there will be an increase of about 25%. Given that there is a significant potential for conservation practices to lead to an increase in carbon sequestration, there are a number of policy options that can be pursued. These include education and technical assistance, financial assistance, research and development, land retirement, and regulation and taxes.

The two subspecies of northern flying squirrels that occur in the southern Appalachians, G. s. coloratus and G. s. fuscus, are endangered species which are primarily found in the ecotone between high-elevation spruce-fir and northern hardwood forests. Our objective was to determine the microhabitat and macrohabitat characteristics associated with the presence and abundance of truffles in suitable habitat for northern flying squirrels. We sampled for truffles in 24-26, 1-m super(2) plots on each of 10 northern flying squirrel sites in North Carolina and measured micro- and macrohabitat characteristics associated with sample plots and sites. Elaphomyces granulatus was the most common species of truffle found (78.7%). Red spruce (Picea rubra) was significantly more likely to be one of the three closest trees to plots with truffles. Further, spruce was the most important species in plots with truffles, followed by beech (Fagus grandifolia), red oak (Quercus rubra) and yellow birch (Betula lutea), whereas the most important species in plots with no truffles were beech, followed by yellow birch, spruce and red oak. At the macrohabitat (site) level, spruce was the most important species in sites with high truffle production followed by beech and red oak, whereas the most important species in sites with low truffle production were beech, yellow birch, spruce and rhododendron (Rhododendron spp.). Significant variables entered into a linear regression model predicting the number of truffles in a site were the importance values of fir (Abies fraseri), spruce and silverbell (Halesia carolina). Our data suggest that spruce-fir or mixed spruce-fir/hardwood stands are important foraging sites for northern flying squirrels in the southern Appalachians.

Canada, United States university experiment stations, United States Department of Agriculture, Agriculture Research Service (ARS), and local weed control groups began an effort to introduce biological control agents for spotted and diffuse knapweed in early 1970 (Table 2). APHIS perceived the need to respond and organize a regional effort to an enormous weed problem. They set up rearing procedures, protocols, established a structure for distribution, and established a protocol for monitoring the establishment and effect of the introduced biological control agents. In 1987, the United States Department of Agriculture, Animal Plant Health Inspection Service, Plant Protection Quarantine (USDA, APHIS, PPQ) in cooperation and consultation with other interested biological weed control groups began a biocontrol program against spotted and diffuse knapweed with the release of three biocontrol agents. By 1998, 13 knapweed biocontrol agents had been released in 17 states and 112 counties. At least one agent has established in each state where introductions were made. Eleven of the 13 agents released by APHIS have become established. Nine of the 13 biocontrol agents are now collectable in some states. Agapeta zoegana is collectable in eight states, Cyphocleonus achates in six states, Larinus minutus in ten states, Metzneria paucipunctella in three states, Sphenoptera jugoslavica in eight states, Terellia virens in one state, Urophora affinis in eight states, Urophora quadrifasciata in ten states and Larinus obtusus is ready to be collected in one state.

Toward this end, we used night-vision cameras and mechanical models to study the interplay of sensory modalities for stimulating predatory behavior in brown treesnakes. Snakes oriented toward live mouse (Mus musculus) lures in complete darkness as much as they did to live mice lures under visible-light illumination; however, brown treesnakes in an unlighted environment responded qualitatively differently by probing and biting at the lure holder rather than striking at the mouse within (as did snakes in lighted trials). We altered the odors and vibratory cues of mechanical models to partition attractive stimuli and to measure snake response to vibratory cues. Fur-covered odorized (by rubbing with freshly defrosted dead neonatal mouse) models were more attractive than fur-covered non-odorized models, odor alone, and empty lure holders. Brown treesnake response to live mice did not differ from their response to smooth, odorized models, and moving versions of the smooth, odorized models stimulated more predatory behavior than unmoving models. Response from brown treesnakes appears to increase as odor and mechanical vibration stimuli are increased quantitatively and-or qualitatively. Conceptually, we hypothesize that polymodal stimuli synergize to promote predatory behavior in foraging snakes and that for trapping purposes, a multi-sensory attractant, optimized at each modality will be required to achieve capture success similar to or better than that obtained using live mice lures.

Commensal rodents such as the Norway rat (Rattus norvegicus) have been implicated in many of these situations. Two chemical repellents (capsicum oleoresin-capsaicin and denatonium benzoate) at 2.0% mass/mass concentrations in a polybutene carrier (Indopol super( registered )-control) were evaluated for repellent efficacy compared to a plastic mesh physical barrier material (Vexar super( registered )) and the polybutene carrier (placebo) alone using groups of individually caged wild Norway rats. The materials were applied to short lengths of communications cable (RG-8U) with the repellents enclosed in electrical shrink tubing around the samples and the plastic mesh attached to the samples for 7 days of continuous rat exposure. Measures of damage taken after rat exposure included mass of cable material damaged, volume loss to gnawing, depth of gnaw penetration, width of gnawing, and a qualitative index of damage based upon visual appearance. Using a stepwise discriminant analysis, we found less damage (P < 0.05) using the volume loss measure (cc) for the capsaicin and for the denatonium groups than for the polybutane-carrier (placebo) group. Other measures of gnawing damage did not improve statistical comparisons of the repellents. For all 5 measures of damage, there was a consistent rank order pattern among the means with capsaicin < denatonium < Vexar super( registered ) < Indopol super( registered )-control.

We exposed three phenologically distinct O. lignaria populations (early-, mid-, and late-flying) to different temperature treatments through development and wintering for a total of nine rearing treatments. These treatments combined three approaches to obtain early bee emergence: (1) exposing bees to warmer or fluctuating temperatures, or both, during development; (2) exposing bees to warmer wintering temperatures; and (3) using early-flying bee populations from Central Valley California latitudes. Extended periods of high prewintering temperatures resulted in apparent fat body consumption of prewintering adults and reductions in springtime adult longevity. In general, temperature treatments that promoted rapid immature development, and thus longer wintering periods, resulted in earlier spring emergence patterns of bees well timed with bloom period of almonds. Warmer wintering periods also resulted in earlier emergence. In addition to providing good bee-bloom synchrony, several treatments also yielded vigorous emerging populations, rapid establishment and nesting, and population increases. The potential importance of our results to anticipated increases in the demand for pollination services in California's Central Valley almonds is discussed.

Heat-killed (HK) bacteria, which initiate an immediate ROS response in plant cells, were used as an elicitor to avoid complications of oxygen consumption by viable bacteria. An increase in oxygen uptake by the tobacco cells occurred within 4 min after addition of HK-bacteria and lasted for about 10 min, returning to a steady state at approximately twice the initial basal rate. The initial burst in oxygen uptake coincided with production of H sub(2)O sub(2). Calculation of the total oxygen consumption by the plant cells indicated that less than 5% of the increased oxygen uptake was utilized in ROS production. Use of respiratory inhibitors indicated that respiration, especially the cytochrome pathway, played a significant role in this response. Results from the use of K-252, a protein kinase inhibitor, and DPI, an inhibitor of membrane bound NADPH oxidases, indicated that triggering of the oxygen uptake response may involve protein phosphorylation and is at least partially activated by the membrane bound NADPH oxidase activity. The involvement of mitochondrial respiration in the oxygen uptake response described here indicates that early events in plant recognition of pathogens involves more of the cellular machinery than previously hypothesized.

Absence of P. gossypiella may be the result of federal regulatory action (e.g., monitoring, quarantine, and eradication), climate, or other ecological factors. The objectives of this study were to determine how low temperatures and high soil moisture common to the southeastern United States might affect mortality of diapausing, preconditioned, and nondiapausing larvae of P. gossypiella. In constant temperature incubators set between 22 and 5 degree C (0% moisture, 0:24 [L:D] h), nondiapausing prepupal (fourth or fifth instar) larvae died more quickly at lower temperatures. At 5 degree C, 90% of the cohort was dead after 12 d. Similarly, prepupal larvae that had been reared under diapause inducing conditions (20 degree C, 10:14 [L:D] h) since neonate stage also died more quickly at lower temperatures. A separate developmental assay indicated that the larvae were not in diapause. In this case, 26 d at 5 degree C were required to achieve 90% mortality. For diapausing, prepupal larvae collected from the field, mortality was greater at 5 degree C than at any other temperature tested, but larvae could withstand 5 degree C for 60 d before 90% of the cohort died. In response to moisture, as soils at 10 degree C became saturated (>195% gravimetric soil moisture), most diapausing larvae ( approximately 60%) died within the first 10 d of the experiment. These studies suggest that diapausing, late instar larvae of P. gossypiella are more resilient to the effects of low temperature than nondiapausing individuals and are able to tolerate high soil moisture for moderate lengths of time. Temperatures and soil moistures in the southeastern United States are not sufficiently cold or wet to completely preclude establishment of P. gossypiella.

The virus was readily transmitted by vascular puncture inoculation (VPI) but not leaf-rub inoculation. Virus symptoms on susceptible maize included pale green, yellow, or cream-colored spots and streaks measuring 1 to 2 mm on emerging leaves 5 to 7 days post-VPI. As leaves developed, the spots and streaks became spindle-shaped, then coalesced into long, chlorotic bands. These bands became translucent and necrotic around the edges. There was a distinctive chlorosis on the stalks that became necrotic. Based on these distinctive symptoms, the new virus was named Maize necrotic streak virus (MNeSV). The virus was not transmitted by Aphis maidis-radicus, Myzus persicae, Macrosiphum euphorbiae, Rhopalosiphum padi, Dalbulus maidis, Graminella nigrifrons, Perigrinus maidis, or Diabrotica virgifera virgifera under persistent or nonpersistent conditions. Both susceptible and resistant maize genotypes were identified following VPI with MNeSV. The isolated virus had isometric (32 nm) virions and a single 29.5-kDa coat protein. MNeSV was serologically distinct from morphologically similar maize viruses. The 4.3-kb single-stranded RNA genome had 25 to 53% sequence identity with species in the family Tombusviridae.

Phytoplasma group-specific polymerase chain reactions (PCRs) and restriction fragment length polymorphism (RFLP) analysis of 16S rDNA revealed that the plants were infected by two mutually distinct phytoplasmas. Clover phyllody-diseased plants were infected by a subgroup 16SrI-C (subgroup I-C) phytoplasma (CPh-L) related to clover phyllody (CPh-C) phytoplasma in Canada. Clover dwarf-diseased plants were infected by both CPh-L and a phytoplasma (CYE-L) related to clover yellow edge (CYE-C) phytoplasma (subgroup 16SrIII-B = III-B) in Canada. A 1.8-kbp fragment of rRNA operon from CYE-L was amplified, cloned, and sequenced, and putative restriction sites mapped. This sequence shared high similarity (99.7%) with that of CYE-C and exhibited no differences from CYE-C in RFLP patterns of 16S rDNA; therefore, we tentatively classified CYE-L in subgroup 16SrIII-B (type strain, CYE = CYE-C phytoplasma) of the X-disease phytoplasma group. These findings extend the known geographical ranges of subgroup I-C and subgroup III-B taxa to the region of northern Europe including Lithuania and suggest a role of the subgroup III-B phytoplasma in clover dwarf disease.

This paper provides a summary of information on the numbers of grizzly bear (Ursus arctos Merriam), gray wolf (Canis lupus Hall and Kelson), Canadian lynx (Lynx canadensis Kurten and Rausch), and wolverine (Gulo gulo Kurten and Rausch), and an overview of current conservation efforts in the North Cascades Ecosystem. Basic research on population status, distribution, habitat needs, and limiting factors is needed for many of these species, because limited field investigations have been conducted in the region. It may be appropriate to approach some research tasks, such as basic surveys and evaluation of habitat connectivity, using a multi-species approach. In addition, a multi-species approach may be appropriate to address conservation issues such as monitoring, human access, and prey species management. By raising the awareness of managers, scientists, and the public about these issues, we hope to recognize the opportunity to recover a full complement of native carnivores and a functioning ecosystem in the North Cascades Ecosystem. This is an opportunity that is becoming extremely limited on a global scale.

To bypass this limitation, several techniques have been useful for Leptospira gene discovery, including heterologous complementation of Escherichia coli mutants, screening of DNA libraries with probes, and random sequence analysis. Construction of combined physical and genetic maps revealed the presence of two circular chromosomal replicons. The organization of the L. interrogans genome is quite variable, with genetically similar strains differentiated by many rearrangements. These rearrangements likely occur through recombination between repetitive DNA elements found scattered throughout the genome. Analysis of intervening sequences and genes encoding LPS biosynthetic enzymes provide evidence of lateral transfer of DNA between Leptospira spp. We have also gained insight into the biology of these bacteria by analyzing genes encoding LPS and outer membrane proteins (OMPs). Some of these OMPs are differentially expressed. Characterization of mechanisms governing the expression of the OMP genes should provide insight into host-parasite interactions. Furthermore, recent advances in heterologous expression of leptospiral OMP genes are opening new avenues of vaccine development.

To assess the possible influence of structure of pteridine derivatives on toxicity of potato glycoalkaloids, a previous study that demonstrated the protective effects of folic acid against the Solanum glycoalkaloid alpha -chaconine-induced toxicity on Xenopus laevis frog embryo cell membranes was extended to two folate analogues--a synthetic compound widely used as a therapeutic agent methotrexate, and naturally occurring L-monapterin. Adverse effects on embryos were evaluated by observing changes in membrane potentials with an electrochromic dye, di-4-ANEPPS, as a fluorescent probe for the integrity of the membranes. Methotrexate decreased alpha -chaconine-induced polarization, as did folic acid. This decrease may result from an alteration of membrane conformations that prevents the binding of the glycoalkaloid to the membrane receptor sites, and/or from effects on folic acid metabolism. In contrast, L-monapterin did not significantly reduce the alpha -chaconine-induced toxicity. The possible significance of these results to food safety is discussed.

Spatial synchrony decreased with distance between local populations and approached zero near 2000 km. Investigation of the synchrony of local population time series with cluster analysis revealed a pattern of geographically distinct blocks of clusters oriented along an east-west axis. Spatial synchrony also was identified in monthly temperature and precipitation time series at 18 weather stations over the same time period and geographical range as the spruce budworm outbreaks. Cross correlations decreased linearly with distance between stations and approached zero near 3000 km and 1800 km, respectively. We developed a spatially explicit lattice model for a single species occupying multiple patches. Within patches, the model had first order logistic dynamics, and patches were linked by dispersal that depended upon their separation distances. Both local and regional stochasticity (i.e., a Moran effect) were present. The modeled lattice had the same spatial configuration as the outbreak region to facilitate investigating the relative effects of a Moran effect and dispersal on spatial synchrony. Simulations with and without a simple region-wide Moran effect and three levels of dispersal did not produce the decrease in spatial synchrony with distance observed with spruce budworm time series. However, when ran at the highest dispersal rate, those simulations produced cluster maps similar to that observed for spruce budworm defoliation. Simulations with a spatially autocorrelated disturbance that had either zero, or high local variability and three levels of dispersal produced decreases in spatial synchrony with distance similar to that observed in the historical data. When run at the highest dispersal rate, simulations yielded cluster maps similar to the cluster map for defoliation. We discuss the potential significance of the spatially autocorrelated disturbance factor in understanding regional insect outbreaks.

We suggest in conclusion that spruce budworm outbreaks were synchronized by a combination of a spatially autocorrelated Moran effect and a high dispersal rate.

Additionally, antibiotics that can elicit production of cold or heat shock proteins were used to determine the effect of translation blockage on ribosome thermal stability. Fatty acid profiles showed no significant variations as a result of cold shock, indicating that changes in membrane fatty acids were not responsible for the cold shock-induced reduction in thermal tolerance. Following a 3-h cold shock from 37 to 0 degree C, the maximum denaturation temperature of the 50S ribosomal subunit and 70S ribosomal particle peak was reduced from 73.4 plus or minus 0.1 degree C (mean plus or minus standard deviation) to 72.1 plus or minus 0.5 degree C (P less than or equal to 0.05), indicating that cold shock induced instability in the associated ribosome structure. The maximum denaturation temperature of the 30S ribosomal subunit peak did not show a significant shift in temperature (from 67.5 plus or minus 0.4 degree C to 66.8 plus or minus 0.5 degree C) as a result of cold shock, suggesting that either 50S subunit or 70S particle sensitivity was responsible for the intact ribosome fragility. Antibiotics that elicited changes in maximum denaturation temperature in ribosomal components also elicited reductions in thermotolerance. Together, these data suggest that ribosomal changes resulting from cold shock may be responsible for the decrease in D value observed when L. monocytogenes is cold shocked.

In this study, treatment with a polyamine analogue (SL-11047) prevented C. parvum infection in suckling TCR- alpha -deficient mice and cleared an existing infection in older mice. Treatment with putrescine, while capable of preventing infection, did not clear C. parvum from previously infected mice. These findings provide further evidence that polyamine metabolic pathways are targets for new anticryptosporidial chemotherapeutic agents.

The gypsy moth cell line, IPLB-LdEIta (Ld), produced similar (not statistically different) amounts of gypsy moth nucleopolyhedrovirus (LdMNPV) occlusion bodies (OBs) in the two media (serum-free Ex-Cell 400 and TC-100 with 9% (v/v) fetal bovine serum, SCM sub(1)) but produced more of the Autographa californica nucleopolyhedrovirus (AcMNPV) OBs in SFM than in SCM sub(1). When Ld cells normally grown in SCM sub(1) were switched to SFM, production of OBs from both viruses improved and, after three passages, reached higher levels of AcMNPV production than in cells normally maintained in that medium. Alternatively, cells switched from SFM to SCM sub(1) initially produced as much (in the case of LdMNPV) or higher (in the case of AcMNPV) levels of virus OBs than cells normally maintained in SCM sub(1) but productivity dropped off over subsequent passages such that after five passages in SCM sub(1), cells produced substantially fewer OBs of both viruses. A fall armyworm cell line (IPLB-SF21AE; Sf) showed slightly different effects from long- and short-term passage in SFM (Ex-Cell 400) or SCM sub(2) (TMN-FH). Cells maintained in SFM produced about 20 times more AcMNPV OBs than cells maintained long-term in SCM. Sf cells switched from SFM to SCM maintained the level of production of that seen in SFM at the first passage, but quickly dropped off OB production levels to that normally seen in SCM. Alternatively, SCM-maintained Sf cells produced higher levels at the first passage in SFM and, within five passages in SFM, reached levels found in cells maintained for long term in this medium. Under the conditions in which these two cell lines were infected, the highest levels of AcMNPV OB production in Ld cells were about five times that of Sf cells. In a separate series of experiments, cells normally grown in SFM were passaged over five times in Ex-Cell 400 to which serum was added; both cell lines produced as much virus as that in SFM. These results suggest that it is not the serum per se but rather some other components which differ between the SFM and the SCM formulations that are responsible for the varied virus production obtained in these studies. The results of these studies suggest that a maintenance and virus production protocol can be developed with Ld cells which could improve overall efficiency of virus production. These studies also suggest that long-term maintenance of cells in SFM was not detrimental to their ability to produce baculoviruses.

For each selected subwatershed, we constructed historical and current vegetation maps from 1932 to 1966 and 1981 to 1993 aerial photos, respectively. Using the raw vegetation attributes, we classified and attributed cover types, structural classes, and potential vegetation types to individual patches within subwatersheds. We characterized change in vegetation spatial patterns using a suite of class and landscape metrics, and a spatial pattern analysis program. We then translated change in vegetation patterns to change in patterns of vulnerability to wildfires, smoke production, and 21 major forest pathogen and insect disturbances. Results of change analyses were reported for province-scale ecological reporting units (ERUs). Here, we highlight significant findings and discuss management implications.Twentieth century management activities significantly altered spatial patterns of physiognomies, cover types and structural conditions, and vulnerabilities to fire, insect, and pathogen disturbances. Forest land cover expanded in several ERUs, and woodland area expanded in most. Of all physiognomic conditions, shrubland area declined most due to cropland expansion, conversion to semi- and non-native herblands, and expansion of forests and woodlands. Shifts from early to late seral conifer species were evident in forests of most ERUs; patch sizes of forest cover types are now smaller, and current land cover is more fragmented. Landscape area in old multistory, old single story, and stand initiation forest structures declined with compensating increases in area and connectivity of dense, multilayered, intermediate forest structures. Patches with medium and large trees, regardless of their structural affiliation are currently less abundant on the landscape. Finally, basin forests are now dominated by shade-tolerant conifers, and exhibit elevated fuel loads and severe fire behavior attributes indicating expanded future roles of certain defoliators, bark beetles, root diseases, and stand replacement fires. Although well intentioned, 20th-century management practices did not account for landscape-scale patterns of living and dead vegetation that enable forest ecosystems to maintain their structure and organization through time, or for the disturbances that create and maintain them. Improved understanding of change in vegetation spatial patterns, causative factors, and links with disturbance processes will assist managers and policymakers in making informed decisions about how to address important ecosystem health issues.

Field rates were measured in small pole-, large pole-, and sawtimber-sized pine stands using two shrubs (Arctostaphylos patula, Ribes cereum) and one graminoid (Carex rossii) as non-fixing reference species. Shrub cover ranged from 23 to 59% for Ceanothus and from 9 to 15% for Purshia. Foliage samples were collected monthly following two applications of super(15)N ammonium sulfate (5 kg N ha super(-1) at 10 atom% super(15)N) to compare N uptake patterns and determine the fraction of N derived from fixation (Ndff). Several violations of the underlying assumption of the isotope dilution method that N fixing and reference plants have access to similar pools of soil super(15)N were identified. These included non-uniform distribution of super(15)N in the soil profile and dissimilarities in rooting volumes, N uptake patterns, and plant ages between the reference and N fixing plants. Despite these compromises, there were only minor differences in percentage of Ndff when calculated independently using each reference species. Low super(15)N uptake by Ceanothus and Purshia evidently negated the requirement that N fixing and reference plants have comparable spatial and temporal access to soil super(15)N. Both Ceanothus and Purshia were highly effective, obtaining more than 80% of their N from fixation regardless of pine stand, shrub cover, or shrub age. Annual N fixation by Ceanothus ranged from 4 to 15 kg ha super(-1) year super(-1). This rate is lower than previously reported for Ceanothus in other ecosystems in the western United States, yet is sufficient to replace N losses from disturbances such as prescribed fire.

Our calculations required four components: total daily shorebird numbers, the daily proportion of each species, average length of stay, and the detection probability. For the 21-d period 26 April-16 May, annual population estimates for Western Sandpiper ranged from 1.2-4.1 million birds per year. Dunlin estimates for this same period ranged from 0.3-0.9 million. For both species, numbers were highest in 1993 and lowest in 1994. Power analysis determined that 15 yr of aerial surveys are needed to detect a 10% decline in Western Sandpiper numbers. Based on the proportion of birds in the Pacific Flyway stopping over on the Copper River Delta, we estimated the Western Sandpiper Pacific Flyway population was >2.8 million in 1992 and >4.3 million in 1995. These data indicate that the Copper River Delta continues to support the largest spring concentration of shorebirds in the Western Hemisphere.

We exposed House Sparrow (Passer domesticus) eggs injected with Rhodamine B dye in camera-monitored ground nests for 12-d periods at 76 sites within mixed-hardwood forest stands in central Massachusetts, June-July 1997. Dye-injected eggs enabled us to recognize with certainty when eggs were breached at the nest because their contents were fluorescent pink and readily detected photographically. Eleven potential predator species were identified disturbing nests, of which eight were confirmed as predators. Eastern chipmunks (Tamias striatus) were the most frequent predators detected, along with fisher (Martes pennanti), raccoon (Procyon lotor), Blue Jays (Cyanocitta cristata), Black-capped Chickadees (Poecile atricapillus), red squirrels (Tamiasciurus hudsonicus), an Eastern Towhee (Pipilo erythrophthalmus), and a white-footed mouse (Peromyscus leucopus). White-footed mice were the most commonly detected species disturbing nests, but were photographed only once actually destroying an egg. The visual cue provided by dye-injected House Sparrow eggs confirmed depredatory behavior by eastern chipmunks, Black-capped Chickadees, an Eastern Towhee, and a white-footed mouse.

Measurements in analysis windows from 81 km 2 (9 x 9 pixels, "small" scale) to 59,049 km 2 (243 x 243 pixels, "large" scale) were used to characterize the fragmentation around each forested pixel. We identified six categories of fragmentation (interior, perforated, edge, transitional, patch, and undetermined) from the amount of forest and its occurrence as adjacent forest pixels. Interior forest exists only at relatively small scales; at larger scales, forests are dominated by edge and patch conditions. At the smallest scale, there were significant differences in fragmentation among continents; within continents, there were significant differences among individual forest types. Tropical rain forest fragmentation was most severe in North America and least severe in Europe-Asia. Forest types with a high percentage of perforated conditions were mainly in North America (five types) and Europe-Asia (four types), in both temperate and subtropical regions. Transitional and patch conditions were most common in 11 forest types, of which only a few would be considered as "naturally patchy" (e.g., dry woodland). The five forest types with the highest percentage of interior conditions were in North America; in decreasing order, they were cool rain forest, coniferous, conifer boreal, cool mixed, and cool broadleaf.

Of the 24 serotypes of BT virus (BTV) identified worldwide, five have been found in the United States. Serotype identification of BTV isolates is important to the epidemiology of the virus, but current methods are cumbersome. A single-tube multiplex reverse transcriptase polymerase chain reaction (mRT-PCR) assay, previously developed for the serotype determination of U.S. BTV isolates, was evaluated. The determination of serotype was based on the size of the resultant amplified product. The procedure was evaluated using all 24 serotypes of BTV and nine serotypes of epizootic hemorrhagic disease virus (EHDV), a closely related orbivirus. Only the five U.S. serotypes of BTV were detected by the mRT-PCR. The assay was further tested using 132 BTV isolates originating from 24 western and southern states of the United States, from several different host species, spanning a period of 24 years. The serotypes of the isolates were determined by both a virus neutralization (VN) procedure and the mRT-PCR. Comparison of the mRT-PCR to the standard VN showed that the mRT-PCR successfully identified the serotypes of 130 of the isolates and was shown to be more reliable and specific than the VN assay.

Single nodes with leaves, derived from in vitro-multiplied material, were used as explants. When delivered at higher concentrations (10 or 50 mu m) both JA and MeJA suppressed node formation. Microtuberisation was supported in all three species by adding either JA or MeJA to the medium. Significant promotory effects were observed only when photoperiod, salt compositions and sucrose concentrations known to favour microtuberisation processes in yams were used. MeJA applied as a vapour strongly inhibited microtuber differentiation inD. alata on all media tested but inD. rotundata andD. cayenensis yams MeJA, also applied in the vapour phase, exhibited slight promotory effects on microtuberisation.

In addition to PCA, an unknown metabolite was discovered in a liquid culture used to produce the biocontrol agent. The objective of the current study was to isolate, identify, and evaluate the accumulation of this compound in production cultures. Upon centrifugal fractionation of a production culture, thin-layer chromatography (TLC) analyses of extracts of the cells and cell-free supernatant indicated the compound to be primarily in the supernatant. Purified compound was obtained by extraction of culture supernatant, followed by flash chromatography of the extract and preparative TLC. The super(1)H and super(13)C nuclear magnetic resonance and electron impact mass spectra indicated the compound to be 2-acetamidophenol (AAP). Measured by reversed-phase HPLC, the accumulations of AAP and PCA in cultures of strain 2-79 reached 0.05 g/l and 1 g/l, respectively. The accumulations of AAP and PCA in liquid cultures were linearly correlated (P 0.001), as shown by studies of cultures stimulated to yield varying levels of PCA by controlling levels of oxygen transfer, pH, and growth medium composition. In this study, oxygen limitation, a defined amino-acid-free medium, and neutral pH stimulated maximal production of both AAP and PCA. Furthermore, a transposon mutant of 2-79 [2A40 2-79 (phz-)] unable to produce PCA did not accumulate AAP. These findings indicate that AAP and PCA are likely to share a common segment of biosynthetic pathway. This is the first report of AAP production by a strain of P. fluorescens. Possible routes of AAP production are discussed relative to current knowledge of the phenazine biosynthetic pathway of strain 2-79. The pertinence of AAP to the design of commercial seed inoculants of phenazine-producing bacteria for controlling wheat take-all is also considered.

We measured tree water flux (Q) for 14 ponderosa pine trees in two size classes (12 m tall and ~40 years old, and 36 m tall and ~ 290 years old) to determine if transpiration (E) and whole-tree conductance (gt) differed between the two sizes of trees. For both size classes, E was approximately equal to Q measured 2 m above the ground: Q was most highly correlated with current, not lagged, water vapor pressure deficit, and night Q was 12% of total daily flux. E for days 165-195 and 240-260 averaged 0.97 mmol m super(-2) (leaf area, projected) s super(-1) for the 12-m trees and 0.57 mmol m super(-2) (leaf area) s super(-1) for the 36-m trees. When photosynthetically active radiation (IP) exceeded the light saturation for photosynthesis in ponderosa pine (900 mu mol m super(-2) (ground) s super(-1)), differences in E were more pronounced: 2.4 mmol m super(-2) (leaf area) s super(-1) for the 12-m trees and 1.2 mmol m super(-2) s super(-1) for the 36-m trees, yielding gt of 140 mmol m super(-2) (leaf area) s super(-1) for the 12-m trees and 72 mmol m super(-2) s super(-1) for the 36-m trees. Extrapolated to forests with leaf area index =1, the 36-m trees would transpire 117 mm between 1 June and 31 August compared to 170 mm for the 12-m trees, a difference of 15% of average annual precipitation. Lower gt in the taller trees also likely lowers photosynthesis during the growing season.

We carried out analyses for the entire region and for grid cells of defoliation maps at five spatial scales created by aggregating the smallest grid cells. The rate of detection of direct density dependence, as assessed by two previously published methods, decreased with increasing spatial scale. Using both methods, density dependence was detected more frequently at the periphery of the outbreak range, where defoliation rate was lower. This result suggested that density-dependent regulation may be stronger in those areas. The first order autoregressive process was the basic model for defoliation dynamics overall and the most common model across spatial scales. Second-order processes were encountered much less frequently, and those commonly identified as resulting from delayed density dependence generally occurred across spatial scales at a rate expected by chance alone. Our results were similar to those of other published studies, which have found the detection of density dependence to decrease at larger spatial scales. The results also reinforced the importance of considering spatial scale when diagnosing population processes using time series of abundance for single species.

To develop a DNA vaccination strategy for coccidiosis, an expression vector pMP13 encoding a conserved antigen of Eimeria was constructed by subcloning 3-1E cDNA into pBK-CMV and used to elicit protective immunity against E. acervulina. One-day-old chickens were immunized intramuscularly (IM) or subcutaneously (SC) with various doses of pMP13 expression vector ranging from 5 to 100 ug two weeks apart and were challenged with 5 x 10 super(3) E. acervulina. Chickens immunized with 5, 10, 50 or 100 ug of pMP13 plasmid, but not control plasmid, pBK-CMV, showed significantly reduced oocysts following challenge infection with E. acervulina. Two injections were in general more effective than one injection with higher dose of DNA eliciting better protection. At 10 days post challenge infection, maximum levels of circulating antibodies were detected regardless of the routes of injection, although IM injection provided higher levels of serum antibodies compared to SC injection. Serum antibody levels demonstrated a dose-dependent response showing higher antibody production at higher DNA dose. DNA immunization with pMP13 also induced significant changes in T-cell subpopulations in the spleen and duodenum intraepithelial lymphocytes. At 4 days post DNA immunization, pMP13-immunized chickens showed lower CD8, and higher CD4 super(+) and gamma delta T super(+) cells in the duodenum compared to the pBK-CMV-immunized chickens. Following challenge infection with E. acervulina, pMP13-immunized chickens showed lower CD8 super(+) and alpha beta T super(+) cells, and higher CD4 super(+) cells than pBK-CMV-immunized chickens in the duodenum. These findings demonstrate that DNA immunization with pMP13 induce local and systemic host immune responses against Eimeria.

AN - 72245538; 10978525 AB - At one end of the 70 kb aflatoxin biosynthetic pathway gene cluster in Aspergillus parasiticus and Aspergillus flavus reported earlier, we have cloned a group of four genes that constitute a well-defined gene cluster related to sugar utilization in A. parasiticus: (1) sugR, (2) hxtA, (3) glcA and (4) nadA. No similar well-defined sugar gene cluster has been reported so far in any other related Aspergillus species such as A. flavus, A. nidulans, A. sojae, A. niger, A. oryzae and A. fumigatus. The expression of the hxtA gene, encoding a hexose transporter protein, was found to be concurrent with the aflatoxin pathway cluster genes, in aflatoxin-conducive medium. This is significant since a close linkage between the two gene clusters could potentially explain the induction of aflatoxin biosynthesis by simple sugars such as glucose or sucrose.

We determined the effects of S. iniae dose and tilapia (Oreochromis niloticus) density on streptococcal disease mortality. Tilapia with a mean weight of 12.7 g were used and maintained at 25 plus or minus 1 degree C in aquaria supplied with flow-through water at 0.5 l/min with a 12 h light:12 h dark cycle. Density and dose were evaluated by stocking tilapia at low (5.6 g/l), medium (11.2 g/l) and high (22.4 g/l) density and administering 2.5 x 10 super(7), 5 x 10 super(7) and 1 x 10 super(8) colony-forming units (CFU)/ml of S. iniae by immersion (5 tanks per density and dose, 45 total tanks). Mortality was monitored for 28 days post challenge. A significant difference (P<0.05) was seen in mortality when comparing low (4.8%) and medium (28.4%) and low and high (25.6%) density treatments. No significant difference was observed when comparing medium- and high-density treatments. Two-way analysis of variance demonstrated density had a significant effect on S. iniae mortality (P=0.0001). Doses had little effect on mortality, except at high density by dose which did show a significant interaction (P=0.001). We have demonstrated density has a significant effect on streptococcal disease mortality in tilapia exposed to S. iniae by immersion. We also evaluated infection of susceptible tilapia using dead/moribund S. iniae infected fish (i.e., cohabitation by placing five dead /moribund fish into tanks for 48 h). No significant difference in mortality pattern was observed between immersion in 8.6 x 10 super(7) CFU/ml S. iniae (37.6% and 34.6%) and cohabitation with S. iniae infected tilapia (24.0%). Although, densities used were less than in most water-reuse production systems (30-290 g/l), tilapia density of 11.2 g/l and above was an important factor in mortality of tilapia infected with S. iniae. A health-management strategy would be to reduce fish density thus lowering streptococcal disease mortality.

Two routes of administration, intraperitoneal (i.p.) and intramuscular (i.m.) injection, were evaluated for vaccine efficacy. Tilapia were vaccinated by i.p. or i.m. injection of the vaccine or tryptic soy broth (control) and challenged by i.p. injection with 1 x 10 super(8) colony-forming units of S. iniae 30 days post-immunization. Tilapia i.p. immunized with ARS-10 vaccine and challenged with the homologous isolate (ARS-10) had a relative percent survival (RPS) of 45.6%. Tilapia i.p. immunized with ARS-10 vaccine and challenged with a heterologous isolate (ARS-60) had an RPS of 93.7%. In contrast, we found that the RPS was 17.7% in tilapia i.m. immunized with the ARS-10 vaccine and challenged with the same isolate, ARS-10. Heterologous (ARS-60) isolate challenge resulted in an RPS of 59.5%. However, the i.m. administration of a vaccine combining the ARS-10+ARS-60 isolates provided an RPS of 63.1 against ARS-10 isolate and RPS of 87.3% against ARS-60 isolate in comparison to RPS of 17.7 and 59.5 against ARS-10 and -60 isolates provided by the single isolate ARS-10 vaccine. Vaccination significantly reduced abnormal behavior and morphology. We found a highly significant (P<0.01) negative correlation between the behavioral and morphological score and RPS. Serologic evaluation revealed that both i.p. and i.m. immunizations stimulated significant (P<0.05) antibody titers in comparison to the non-immunized tilapia. Significantly (P<0.05) increased antibody titers were also produced by i.m. immunization of the combined ARS-10+ARS-60 vaccine. Administration of the single isolate ARS-10 vaccine by i.m. injection was marginally protective in preventing streptococcal disease caused by homologous and heterologous isolates of S. iniae. The variability seen in the protective ability of a single S. iniae isolate vaccine indicates that antigenic heterogeneity exist in S. iniae. Recognition of this antigenic variability is very important to development of efficacious streptococcal vaccines. Thus, this research suggests that efficacious vaccines, that may be administered by either i.p. or i.m. injection, are dependent on the antigenic composition of the S. iniae.

Each locus consisted of the 16S rRNA gene (rrs), followed by an intergenic spacer containing the tRNA-Ile and tRNA-Ala genes, the 23S rRNA gene (rrl), an intergenic spacer devoid of tRNA genes, the 5S rRNA gene (rrf), and an f-Met tRNA gene. The DNA sequences were identical over a 6271 bp region, diverging 594 bp upstream of rrs and immediately downstream of the f-Met tRNA gene. The previously uncharacterized 23S rRNA genes each contained a 178 bp insertion 130 bp from the 5' end. The location of the insertion matched intervening sequences (IVSs) found in other Rhizobiaceae. However, the size and sequence of the Brucella IVS differed from all previously reported IVS sequences from bacteria. The IVS region was PCR-amplified from 20 Brucella isolates representing all known Brucella species and biovars. All isolates contained only the complete IVS fragment. We compared the IVS DNA sequences of rrlC from representative strains of each of the six known Brucella species. The data revealed that the sequences were identical and differed from the B. melitensis IVS sequences by a single base pair. In other bacterial species, the IVSs are associated with post-transcriptional processing of the 23S rRNA by RNase III. We found that the Brucella 23S rRNA was slightly smaller than the 23S rRNA of Escherichia coli, known to be devoid of IVS sequences.

AN - 72357335; 11048870 AB - Deoxynivalenol (DON), a toxin produced by Fusarium fungi, can occur in many cereal grains. If wet climatic conditions coincide with the flowering period of plant development, circumstances are favorable for the fungi infection. Because the presence of DON in barley can have significant economic consequences to barley producers, commercially available test kits are used to measure DON in shipments throughout marketing channels. The quantity of barley sampled from a lot and used to measure DON can vary widely, depending on where the test is conducted. The Grain Inspection, Packers and Stockyards Administration of the U.S. Department of Agriculture specifies that a minimum of 100 g of grain must be processed to measure DON. Other laboratories may use more or less grain. A study undertaken to measure the variability among measurements of different sample sizes found no detectable differences in variability attributable to sample size. It was concluded that the variability among DON concentrations in samples from the lot was small relative to that introduced by the measurement process (combined sample preparation and analysis). A separate experiment investigated variation among samples taken from a lot, variation among subsamples taken from ground samples, and variation among multiple replicated measurements of an extract. On 10 lots, all 3 sources were significant contributors to variation. Stratification of DON within lots was hypothesized as a source of variation of DON measurements.

AN - 72311267; 11015120 AB - We exposed midgut cells from primary cultures of Heliothis virescens larvae to cell-free previously used medium, the Vaughn X and HyQ SFtrade mark media used for serum-free culture of insect cell lines which do not support H. virescens midgut cells, and to toxin from Bacillus thuringiensis. A statistically significant increase in the percent of dying cells was counted in cell populations in Vaughn X medium. Use of the TUNEL method to detect apoptosis indicated a low rate (7.2%) of apoptosis in control cultures grown in Heliothis medium, an increase to approximately 20% in previously used and HyQ SFtrade mark media, and to approximately 45% of cells remaining after exposure to and initial destruction by B. thuringiensis toxin. Apoptotic nuclei were predominant (approximately 6%) in mature columnar cells in control cultures. Approximately 1% of goblet, stem, and differentiating cells were apoptotic. However, apoptosis rose to 12% in stem and differentiating cells exposed to used and unsuitable medium. B. thuringiensis exposure to toxin for 2-3 days resulted in visible membrane damage and necrosis, causing the death of 84% of the cells as measured by both the TUNEL and Annexin methods. Some of the columnar cells and stem and differentiating cells that remained also contained apoptotic nuclei. Stem and differentiating cells normally replace dying mature cells in the midgut. Thus, exposure of cultures of H. virescens midgut cells to adverse environments such as unsuitable or poisonous media appeared to induce down-regulation of the cell populations by apoptosis.

AN - 72286244; 10996037 AB - Fumonisins represent a family of toxic, structurally related metabolites produced by fungi that are found in corn worldwide. We investigated the effects of the mycotoxin, fumonisin B(1), on rat splenic macrophage and lymphocyte functions. Pretreatment (24 h) of resident macrophages with fumonisin B(1) (1, 10, and 100 microg/ml) significantly (p<0.01) stimulated nitric oxide production (0.48, 2. 60, and 4.40 nmol nitrite/well, respectively), compared with the response of untreated macrophages (no nitrite detected), after 72 h of culture. Fumonisin B(1) (1 and 10 microg/ml) and IFN-gamma acted in an additive manner to activate nitric oxide production. The response of IFN-gamma (50 U/ml)-activated macrophages (1.68 nmol nitrite/well) was potentiated (3.52, 4.96, and 4.44 nmol nitrite/well) by fumonisin B(1) (1, 10, and 100 microg/ml, respectively). In addition, fumonisin B(1) significantly (p<0.05) potentiated Con A (1.25 to 5 microg/ml) (1.46- to 2.62-fold increases)- and antiTCR, IL-2 or antiTCR+IL-2 (1.72- to 2.60-fold increases)-induced proliferation of splenic cells in the presence of the nitric oxide synthase inhibitor N(G)-monomethyl-L-arginine (NMA). These results show two distinct and separate effects of fumonisin B(1): it induces nitric oxide production by macrophages and it stimulates T cell proliferation.

Sequential sampling. AN - 72271548; 10995364 AB - Sequential sampling for aflatoxin testing in pistachios is evaluated using the aflatoxin distribution and Monte Carlo results previously obtained (J. Agric. Food Chem. 1999, 47, 3771-3775). The sequential protocol is modeled on the current EU test protocol by applying a three-step sampling, using 10, 20, and 30 kg sample averages. An acceptance level of 15 ng/g of total aflatoxin, under consideration for U.S. standards, is applied. Optimization leads to indifference regions of 2-30 ng/g for the first two steps. The resulting OC curve approximates that for a single 50 kg sample. The sequential protocol is applied to the results for a set of 1293 lots of the 1998 crop year, each tested with a single 10 kg sample. Ninety-five percent of the lots would have been accepted on the basis of the single test and 1.5% would have been rejected, whereas 3.5% of the lots would have required retesting.

AN - 72270574; 10995372 AB - Walnuts are a valuable crop the sale and export potential of which may be severely limited by contamination with aflatoxins, metabolites produced on infection with Aspergillus flavus. The effect of a series of four naphthoquinones [1,4-naphthoquinone (1); juglone (5-hydroxy-1,4-naphthoquinone) (2); 2-methyl-1, 4-naphthoquinone (3); and, plumbagin (5-hydroxy-2-methyl-1, 4-naphthoquinone) (4)] (Figure 1), which occur in walnut husks, on fungal viability and aflatoxigenesis was studied in vitro. The quinones delayed germination of the fungus and were capable of completely inhibiting growth at higher concentrations. Their effect on aflatoxin levels was highly dependent on the concentration of individual naphthoquinones in the media. At higher concentrations, aflatoxin production was decreased or completely inhibited, but at lower concentrations there was a stimulatory effect on aflatoxin biosynthesis, with a >3-fold increase at 20 ppm of 3. Structural features associated with decreased fungal viability and greatest effect on aflatoxigenesis are the presence of a 5-hydroxyl or 2-methyl substituent, but there is no significant additive effect when both of these substituents are present.

AN - 72269882; 10995322 AB - A multiresidue procedure was developed for analysis of cotton pesticide and harvest-aid chemicals in water using solid-phase extraction and analysis by GC-NPD, GC-MS, and HPLC-DAD. Target compounds included the defoliants tribufos, dimethipin, thidiazuron; the herbicide diuron; and the insecticide methyl parathion. Three solid-phase extraction (SPE) media, octadecylsilyl (ODS), graphitized carbon black (GCB), and a divinylbenzene-N-vinyl pyrollidine copolymer (DVBVP), were evaluated. On GCB and ODS, recoveries varied depending on compound type. Recoveries were quantitative for all compounds on DVBVP, ranging from 87 to 115% in spiked deionized water and surface runoff. The method detection limit was less than 0.1 microg L(-)(1). SPE with DVBVP was applied to post-defoliation samples of surface runoff and tile drainage from a cotton research plot and surface runoff from a commercial field. The research plot was defoliated with a tank mixture of dimethipin and thidiazuron, and the commercial field, with tribufos. Dimethipin was detected (1.9-9.6 microg L(-)(1)) in all research plot samples. In the commercial field samples, tribufos concentration ranged from 0.1 to 135 microg L(-)(1). An exponentially decreasing concentration trend was observed with each successive storm event.

AN - 72268964; 10995370 AB - Roots of a citrus relative, Glycosmis pentaphylla (orangeberry), were shown to inhibit the growth and survival of larvae of the citrus root weevil Diaprepes abbreviatus. Roots of G. pentaphyllaincorporated into the diet of D. abbreviatus increasingly inhibited the growth of neonate larvae with increased concentration of roots, while roots from citrus rootstocks produced little inhibition. The diet-incorporation assay was used to guide fractionation of an active acetone extract of G.pentaphylla roots. Three major fractions from silica open-column liquid chromatography were active, and these were purified using semipreparative normal-phase HPLC. A single active HPLC subfraction was isolated from each of the three liquid chromatography fractions, and two active compounds were isolated and identified by GC-MSD. GC-MSD and NMR identified one compound as the amide dehydrothalebanin B, and the other was identified by GC-MSD as dieldrin, a chlorinated hydrocarbon insecticide whose origin in our samples is uncertain.

Altered metal accumulation and increased manganese tolerance. AN - 72255413; 10982428 AB - Metal transport from the cytosol to the vacuole is thought to be an important component of ion tolerance and of a plant's potential for use in phytoremediation. The Arabidopsis antiporter CAX2 (calcium exchanger 2) may be a key mediator of this process. CAX2 expression in yeast suppressed both Ca(2+) and Mn(2+) growth defects. A peptide-specific antibody to the antiporter reacted with a 39-kD protein from plant vacuolar membranes. Tobacco (Nicotiana tabacum) plants expressing CAX2 accumulated more Ca(2+), Cd(2+), and Mn(2+) and were more tolerant to elevated Mn(2+) levels. Expression of CAX2 in tobacco increased Cd(2+) and Mn(2+) transport in isolated root tonoplast vesicles. These results suggest that CAX2 has a broad substrate range and modulation of this transporter may be an important component of future strategies to improve plant ion tolerance.

AN - 72248083; 10983808 AB - We recently reviewed the Food Safety and Inspection Service's (FSIS's) inspection procedures for lambs. As a result, FSIS published a Federal Register notice informing the public of its intent to change from an inspection system that requires extensive carcass palpation to an inspection system that requires no carcass palpation for lambs. This decision was based on the following three points. (i) Extensive carcass palpation in lambs does not routinely aid in the detection of food safety hazards that result in meat-borne illnesses. (ii) Hands are capable of spreading or adding contamination to the carcasses. (iii) FSIS inspection systems must reflect science-based decisions as they pertain to meat-borne illnesses consistent with a Pathogen Reduction/Hazard Analysis and Critical Control Point environment.

AN - 72244381; 10983790 AB - Scald water samples from a commercial broiler processing plant were tested for coliforms, Escherichia coli, and salmonellae to evaluate the numbers of suspended bacteria in a multiple-tank, counterflow scalder. Water samples were taken from each of three tanks on 8 different days after 6-week-old broilers had been processed for 8 h. Coliforms and E. coli were counted using Petrifilm, and the most probable number (MPN) of salmonellae was determined both in water samples and in rinses of defeathered carcasses that were removed from the processing line immediately after taking the water samples. Mean coliform concentrations in tanks 1, 2, and 3 (the last tank that carcasses pass through before being defeathered) were 3.4, 2.0, and 1.2 log10(CFU/ml), respectively. E. coli concentrations followed the same pattern with means of 3.2, 1.5, and 0.8 in tanks 1, 2, and 3, respectively, with significant differences (P < 0.02) in the concentrations of both coliforms and E. coli between the tanks. Sixteen of 24 scald-water samples were positive for salmonellae with a geometric mean of 10.9 MPN/100 ml in the positive samples. Salmonellae were isolated from seven of eight water samples from both tanks 1 and 2, but in only two of eight water samples from tank 3, the last tank that carcasses pass through. It appears that most bacteria removed from carcasses during scalding are washed off during the early part of scalding.

AN - 71731189; 10930700 AB - Fumonisin B(1) is a fungal inhibitor of ceramide synthase, a key enzyme in the de novo biosynthesis of sphingolipids. The resulting increase in tissue free sphinganine (and sometimes sphingosine) is used as a biomarker for fumonisin exposure. This study determined whether a single subcutaneous injection of fumonisin B(1) could cause an increase in free sphingoid bases in the intestinal epithelial cells of mice over 24 hr. It was hypothesized that fumonisin administered subcutaneously would be excreted into the small intestine via biliary excretion, and this should be detectable by increased sphingoid bases in the intestine. A significant time-dependent increase in sphingoid bases occurred in the intestine and liver peaking at 4-8 hr and declining to control levels by 24 hr. In the kidney the increase in free sphinganine was persistent. The parallel time course of the change in sphinganine in the intestine and liver suggested fumonisin B(1) was rapidly excreted into the small intestine. Rapid cell turnover in the intestine could account for the reversal of the sphinganine increase. The rapid return to the control level in liver was unexpected since ceramide synthase inhibition in cultured cells is persistent suggesting that liver handles fumonisin B(1) or sphingoid bases quite differently than kidney.

Urinary calcium was elevated significantly (relative to controls) in all groups. The order of hypercalciuric activity was 1,25-(OH)(2)D(3) >/= 1,24-(OH)(2)D(3) >/= 1,24-(OH)(2)D(2) > control. Duodenal plasma membrane calcium ATPase (PMCA) mRNA was elevated to a similar extent in all groups relative to controls. Duodenal 24-hydroxylase mRNA was elevated in all groups relative to controls; however, the elevations were significantly higher in the 1,24-(OH)(2)D(3) and 1, 25-(OH)(2)D(3) groups compared with the 1,24-(OH)(2)D(2) group. Kidney 24-hydroxylase also was elevated significantly in the 1, 24-(OH)(2)D(3)- and 1,25-(OH)(2)D(3)-treated rats but not in the 1, 24-(OH)(2)D(2)-treated rats. Recombinant human vitamin D receptor (hVDR) extracts were incubated with saturating concentrations of 1, 24-(OH)(2)D(2), 1,24-(OH)(2)D(3), and 1,25-(OH)(2)D(3) and subsequently analyzed by electrophoretic mobility shift assay (EMSA). Overall binding was comparable for all metabolites; however, the 1, 24-(OH)(2)D(2) complex exhibited distinctly altered mobility relative to 1,24-(OH)(2)D(3) and 1,25-(OH)(2)D(3), suggestive of an effect on hVDR/hRXR conformation. These data suggest that 1, 24-(OH)(2)D(2) is not as potent as either of the vitamin D(3) sterols at affecting hypercalcemia or hypercalciuria in young growing rats; however, 1,24-(OH)(2)D(2) can evoke other biological responses similar to the vitamin D(3) sterols. These different responses may be related to the alterations in conformation state of the hVDR/hRXR heterodimer.

In contrast to current methods of evaluating the climate effect, a realistic seasonal snow cover from satellite monitoring is used to represent the present climate. The non-calibrated SRM model is applied to transform this snow cover under conditions of a warmer climate and to compute the climate-affected runoff. The winter snow accumulation is particularly reduced in the Kings River basin which has the greatest elevation range. In absolute terms, the smallest snowpack reduction occurred in the semi-arid basin of Rio Grande at Del Norte. The decline of snow covered area in the snowmelt season in accelerated by about one month in all basins. The runoff in the winter half year is about doubled at the expense of the summer half year in the basins Illecillewaet and Kings River. This effect is smaller in the basin Rio Grande at Del Norte. Because the climate change was limited to a temperature increase, there is no significant change in the yearly runoff volume in the basins Kings River and Rio Grande. There is a yearly runoff increase in the Illecillewaet basin due to enhanced glacier melt.

The 10 most frequently listed weeds are Cirsium arvense, Carduus nutans, Lythrum spp. (includes purple loosestrife), Convolvulus arvensis, Euphorbia esula, Acroptilon repens, Sorghum spp. (includes johnsongrass and shattercane), Cardaria spp. (includes hoary cress, also called whitetop), Centaurea maculosa, and Sonchus arvensis. When genera are ranked, the top genus is Centaurea, which includes C. maculosa,C. diffusa, and C. solstitalis. Biological control programs have targeted many of the top dicotyledonous weeds of national concern, but none of the weedy grasses and sedges. We recommend that exploratory studies be initiated to determine the feasibility of developing biological control agents for the latter species. The complete database of noxious weed lists is available on the Internet at http://invader.dbs.umt.edu. This information may be useful to resource managers and regulatory officials in assessing which weeds are problematic in adjacent geographic areas and by researchers to help select which weeds to target with new management strategies.

Saturated hydraulic conductivity is increased by fractures, in some cases by two or more orders of magnitude. This in turn results in larger values for the coefficient of consolidation, c sub(v), governing the rate of consolidation. A larger c sub(v) corresponds to faster settlement. Modest increases in total settlement occur only if fractures are open. Fractures also have the overall effect of reducing shear strength. Upon removal of surface material by excavation or erosion, stress release and water infiltration lead to further decreases in shear strength. This strength loss process, called softening, is due mostly to a decrease in effective cohesion and usually takes years to complete. Once failure occurs, there is another substantial drop in shear strength to a residual value. This residual strength is a result of realignment of particles along the failure plane during shear, which decreases the effective angle of internal friction. The fracture impact magnitude on glacial till saturated hydraulic conductivity, consolidation potential, and shear strength is determined largely by aperture and spacing characteristics. As the number and/or size of fractures increase, changes in these geotechnical properties become more pronounced.

This study was conducted to illustrate the extensive presence of fractures in the till and to quantify the differences in hydraulic conductivity and physical and chemical properties between the fracture-affected zones and the till matrix. In situ measurements of the saturated hydraulic conductivity were made in small boreholes positioned either in the matrix or intersecting the fractures. Soil samples from both the fracture faces and the matrix were analyzed for particle size distribution, clay mineralogy, calcite, dolomite, and iron content. Hydraulic conductivity measured in boreholes intersecting fractures was 1.25 x 10 super(-5) cm/sec (0.018 in/hr), one order of magnitude greater than in boreholes in the matrix. Particle size distribution was the same for the fracture faces and the matrix. The fracture faces showed no significant change in total clay content and a slight increase in expandable clay. Calcite content was 62% greater, dolomite content was 6% lower, and iron content was 73% lower on the fracture faces as compared to the matrix. The fractures affected approximately 7% of the soil volume.

Most of this work has utilized sensors operating in the visible and infrared regions of the electromagnetic spectrum. A notable example is the use of visible and near infrared sensors to provide land cover and vegetation information. This work began with the Landsat satellites in 1972. Improved technologies have resulted in higher spatial resolution and more frequent observations. This has broadened the use of the data in water resources applications. Examples include mapping and monitoring snow cover for forecasting water supply and flood prediction. Recent developments in both science and associated antenna technologies now make the exploitation of the microwave region feasible. Wavelengths in the microwave portion of the spectrum are orders of magnitude longer than those in the visible and infrared regions. These waves originate within the volume of the target and the magnitude of the signal is directly related to the amount of water present in that volume. This feature makes microwave remote sensing particularly attractive in water resources studies.

To study the effects of fire in naturally accumulating fuel conditions, the ambient soil temperature is monitored beneath prescribed burns. In this study we developed a stochastic model for temperature profiles (values at 15 minute intervals) recorded at four depths beneath the soil during a large prescribed burn study. The model was used to assess the temporal fit of the data to particular solutions of the heat equation. We used a random effects model to assess the effects of observed site characteristics on maximum temperatures and to estimate risks of temperatures exceeding critical levels in future similar prescribed fires. Contour plots of estimated risks of temperatures exceeding 60 degree C for a range of fuel levels and soil depths indicated high risks of occurrence, especially when the moisture levels are low. However, the natural variability among sites seems to be large, even after controlling fuel and moisture levels, resulting in large standard errors of predicted risks.

Some strains fermented L-(-)-arabinose and L-rhamnose. D-Xylose was not fermented and starch was not hydrolysed. The mean G+C content of the DNA was 48 mol%. Phylogenetic analyses of 16S rDNA established that the isolates were members of the genus Lactobacillus. DNA reassociation of 45% or less was obtained between the new isolates and the reference strains of species with G+C contents of about 48 mol%. The isolates were differentiated from other homofermentative Lactobacillus spp. on the basis of 16S rDNA sequence divergence, DNA relatedness, stereoisomerism of the lactic acid produced, growth temperature and carbohydrate fermentation. The data support the conclusion that these organisms represent strains of a new species, for which the name Lactobacillus arizonensis is proposed. The type strain of L. arizonensis is NRRL B-14768(T)(=DSM 13273(T)).

Although not displayed by all strains, mosquito pathogenicity is a noteworthy characteristic of B. sphaericus sensu lato. Phylogenetic analysis based on 16S rDNA sequences from 58 strains identified as B. sphaericus was used to examine the genetic heterogeneity of the taxon. Results from sequence analysis were compared with whole-cell fatty acid profiles and other phenotypic determinations. The B. sphaericus-like strains segregated into seven distinct clusters in a phylogenetic tree generated from 16S sequences. One cluster represented B. sphaericus and another B. fusiformis. A third cluster containing all of the pathogenic strains was closely related to, or was possibly part of, the B. fusiformis group. The remaining four groups were distinct and represented unnamed taxa that were more closely related to B. sphaericus and B. fusiformis than to the psychrophilic round-spored species, Bacillus globisporus and Bacillus psychrophilus. Groups based on phenotypic analysis corresponded to the 16S rDNA phylogenetic clusters. Data showed that B. sphaericus was genetically and phenotypically a highly heterogeneous taxon including at least seven genetically distinct taxa. The pathogenic strains were members of a distinct group and not of the species B. sphaericus sensu stricto. This heterogeneity partially accounts for the apparent variability of mosquito pathogenicity among B. sphaericus strains.

It has been hypothesized that the two copies can serve for antigenic phase variation. Analysis of polymorphisms within aligned multiple DNA sequences of the Campylobacter flagellin genes revealed high pairwise homoplasy indexes between flaB/flaB pairs that were not observed between any flaA/flaA pairings or flaA/flaB pairings. Thus it seems there are constraints on the sequence of flaB that distinguish it from flaA. Nevertheless, segments of the two genes that are highly variable between strains are conserved between the flaA and flaB copies of the genes within a strain. The patterns of synonymous and non-synonymous differences suggest that one segment of the flagellin sequence is under selective pressure at the amino acid sequence level. Another segment of the protein is maintained within a strain by conversion or recombination. Comparisons of strict consensus amino acid sequences did not reveal any motifs that are uniquely FlaA or FlaB, but there are differences between FlaA and FlaB in those amino acids available for post-translational modification. The observed pattern of concerted evolution of portions of a structural gene is an unusual finding in bacteria and should be searched for with other duplicated genes. Concerted evolution was unexpected for genes involved in phase variation since it minimizes the antigenic repertoire that can be expressed by a single clone in the face of the host immune response.

A numerical solute transport simulator, that incorporates rate-limited dissolution and desorption using linear driving force expressions, was developed and applied to analyze soil column dissolution data and to conduct numerical dissolution experiments. Published mass transfer coefficients were unable to accurately predict the observed dissolution of entrapped PCE in fractional wettability porous media (media containing both water- and PCE-wet solid surfaces). A two-parameter power function expression for the lumped mass transfer coefficient was developed and successfully fit to these data. Correlations were then developed for the fitted mass transfer model parameters as a function of wettability and grain size distribution characteristics. The power function model, in conjunction with the parameter correlations, yielded reasonable predictions for long-term dissolution behavior in the more PCE-wetting media. Poorer predictions for the more water-wet materials were attributed to an increased sensitivity of effluent concentration behavior to temporal changes in PCE saturation in these systems. Many of the effluent concentration curves exhibited low and persistent concentration tailing after recovery of the separate phase PCE. This tailing behavior could be adequately modeled by incorporation of rate-limited desorption. Results from numerical experiments indicate that both the magnitude and spatial distribution of wettability can significantly influence PCE dissolution behavior and remediation time.

This paper describes our work on developing a protocol for cryopreservation of embryos of the housefly, Musca domestica. Significant progress was made when permeabilization of the vitelline membrane was optimized, a vitrification solution containing ethylene glycol, polyethylene glycol, and trehalose was formulated, and when cooling and recovery of the cryopreservation protocol included a step which passed the embryos through liquid nitrogen vapor. More than 70% of housefly embryos withstand treatments of dechorionation, permeabilization, loading with cryoprotectant, and dehydration in vitrification solution, but the cooling, warming, and poststorage rearing steps still cause a considerable reduction in survival. About 53% of the vitrified M. domestica embryos hatched into larvae. Relative to the percentage of the control adult emergence, about 13% of the embryos stored in liquid nitrogen developed into fertile adults. Hatching of the F sub(1) progeny of adults having been cryopreserved as embryos was similar to control levels. Copyright 2000 Academic Press.

Cultivar specificity is governed by a plasmid-borne locus, nolXBTUV. By DNA sequence analysis, we have identified two open reading frames, y4yA and y4yB, immediately downstream of nolX. Northern (RNA) blot analysis indicated that the expression of both y4yA and y4yB is inducible by isoflavonoids, and an intact copy of nolX is required. Two copies each of y4yA and y4yB are present in S. fredii USDA257, one on the sym plasmid (y4yAsp and y4yBsp), and the other on the chromosome (y4yAc and y4yBc). The cultivar-nonspecific strain USDA191 lacks y4yAc and y4yBc. Introduction of y4yAc plus y4yBc from USDA257 into USDA191 did not influence the ability of the latter strain to nodulate McCall soybean plants. Unlike nolX, the inactivation of y4yAsp and y4yBsp of USDA257 did not extend the host range of this strain. A double mutant, in which both the plasmid and chromosomal copies of y4yA and y4yB were mutated, had no observable effect on symbiotic ability of USDA257. The y4yAsp and y4yBsp mutants did not influence flavonoid-dependent extracellular protein production. Rhizobium sp. strain NGR234 and S. saheli USDA4893 both contain sequences similar to S. fredii USDA257 y4yAsp and y4yBsp; however, Bradyrhizobium spp., the traditional soybean symbionts, lack these genes.

Long-term soil and water retention varies directly with vegetation cover. Data on ground cover and plant species composition were collected from 129 sites in the Rio Grande drainage of south-central New Mexico. This area was previously assessed by classification of Advanced Very High Resolution Radiometry (AVHRR) imagery. The classification of irreversibly degraded sites failed to identify most of the severely degraded sites based on size of bare patches and 35% of the sites classified as degraded were healthy based on mean bare patch size and vegetation cover. Previous research showed that an index of unvegetated soil (bare patch size and percent of ground without vegetative cover) was the most robust indicator of the soil and water retention function. Although the regression of mean bare patch size on percent bare ground was significant (p < 0.001), percent bare ground accounted for only 11% of the variability in bare patch size. Therefore bare patch size cannot be estimated from data on percent bare ground derived from remote sensing. At sites with less than 25% grass cover, and on sites with more than 15% shrub cover, there were significant relationships between percent bare soil and mean bare patch size (p < 0.05). Several other indicators of ecosystem health were related to mean bare patch size: perennial plant species richness (r = 0.6, p < 0.0001), percent cover of increaser species (r = 0.5, p < 0.0001) and percent cover of forage useable by livestock (r = 0.62, p < 0.0001). There was no relationship between bare patch size and cover of species that are toxic to livestock. In order to assess the ability of western rangeland watersheds to retain soil and water using remote sensing, it will be necessary to detect and estimate sizes of bare patches ranging between at least 0.5 m in diameter to several meters in diameter.

This fact, coupled with the need to revise current planning direction for range allotments of the LMNG, necessitated that a broad-level characterization of ecosystem integrity and resource conditions be conducted across all lands within the study area (approximately 800,000 hectares) in a rapid and cost-effective manner. The approach taken in this study was based on ecological classifications, which effectively utilized existing field plot data collected for a variety of previous inventory objectives, and their continuous spatial projection across the LMNG by maps of both existing and potential vegetation. These two map themes represent current and reference conditions (existing vs. potential vegetation); their intersection allowed us to assign various ecological status ratings (i.e., ecosystem integrity and resource condition) based on the degree of departure between current and reference conditions. In this paper, we present a brief review of methodologies used in the development of ecological classifications, and also illustrate their application to assessments of rangeland health through selected maps of ecological status ratings for the LMNG.

Each year this compound, also known as 'vomitoxin' causes substantial losses to agricultural productivity. Three monoclonal antibodies were developed following the immunization of mice with a conjugate of DON and ovalbumin. One of these antibodies, produced by clone #22, was selected for the development of a competitive direct ELISA (CD-ELISA). This format consists of competition between a DON horseradish peroxidase conjugate (DON-HRP) and free DON for antibody attached to microwell plates. Color development in the assay was inhibited 50% (IC sub(50)) by 18 ng DON/ml in phosphate-buffered saline (PBS). The antibody from this clone showed strong cross-reactivity to 3-acetyl deoxynivalenol (3-Ac-DON), with an IC sub(50) of 2.9 ng ml super(-1) Cross-reactivity to 19 other trichothecene mycotoxins was low. The CD-ELISA was applied to wheat spiked with DON over the range 0.01-10 mu g/g and extracted with a l0-fold excess of PBS. The midpoint for color development in the assay using this extraction was 0.27 mu g DON/g wheat. Recoveries over the range 0.05-5 mu g/g averaged 88.7% with a coefficient of variation of 10.9%. This assay is sufficiently sensitive and rapid to permit the screening of DON in wheat below the US Food and Drug Administration advisory level of 1 ppm in human food.

One population was located on private land in Perry County and the other was located in Mark Twain National Forest in Phelps County. Courtship and insemination probably occurred between December and March. Oviposition occurred during May or June and eggs hatched during July or August. Gravid females contained an average of 6.3 (range 4-10) enlarged ovarian follicles. We assume that reproduction among females is biennial on the basis of two distinct groups of mature females, those with enlarged, yolk-filled follicles and those with only small follicles. Hatchlings emerged in September and October and averaged 17 mm SVL (range 15-20 mm SVL). The growing season extended from September to May and little growth occurred during June to August. Growth during the first year after hatching averaged 10 mm. Plethodon serratus was most active on the forest surface between October and May in Phelps County and August and May in Perry County. The life-history pattern observed for P. serratus has characteristics of other small temperate plethodontid salamanders.

EMDS integrates geographic information system and knowledge base system technologies to provide an analytical tool for environmental assessment and monitoring. The basic objective of EMDS is to improve the quality and completeness of environmental assessments and the efficiency with which they are performed. The USDA Forest Service and the U.S. Environmental Protection Agency have cooperatively developed an EMDS knowledge base for watershed condition assessment. Specifically, this knowledge base evaluates watershed processes, patterns, general effects of human activity, and fisheries habitat suitability. Such assessments are based on spatially explicit input data concerning current conditions and reference conditions which are subsequently interpreted by user-defined "fuzzy" membership functions. In this paper we describe basic components of our knowledge base for assessing watershed condition and illustrate its application within northern Idaho and northwestern Montana.

The effort included an integrated assessment of 58.3 million ha in seven states describing the Basin's current conditions and risks associated with different management strategies. The assessment provides the foundation for environmental impact statements outlining management direction for 31 million hectares of FS and BLM administered lands. The process produced a framework for ecosystem management, ecosystem component (social, economic, landscape, terrestrial, and aquatic) assessments, and estimates of ecological integrity and socioeconomic resiliency.

This approach has not been emphasized by the agrochemical industry, although the possibility of discovering new target sites may be promising, since natural products tend to have modes of action different from synthetic herbicides. The approach of testing a compound on all known herbicide molecular target sites for commercial herbicides and other potent phytotoxins is feasible. However, this would preclude the discovery of new mechanisms of action. Discovering new target sites requires more challenging holistic approaches, initiated with physiological and biochemical studies that use whole plant assays. Studying basic plant responses to a compound may yield important clues to the specific physiological processes affected by the compounds and uncover novel mechanisms of action.
