Specifically, three experiments were conducted to: 1) determine the effect of belt grill (BG) cookery on repeatability of pork longissimus Warner-Bratzler shear force (WBSF), 2) compare the correlation of WBSF and slice shear force (SSF) with trained sensory panel tenderness ratings, and 3) estimate the repeatability of pork longissimus SSF for chops cooked with a BG. In Exp. 1 and 2, the longissimus was removed from the left side of each carcass (Exp. 1, n = 25; Exp. 2, n = 23) at 1 d postmortem and immediately frozen to maximize variation in tenderness. In Exp. 1, chops were cooked with either open-hearth electric broilers (OH) or BG, and WBSF was measured. Percentage of cooking loss was lower (P < 0.001) and less variable for chops cooked with a BG (23.2%; SD = 1.7%) vs. OH (27.6%; SD = 3.0%). Estimates of the repeatability of WBSF were similar for chops cooked with OH (0.61) and BG (0.59). Although significant (P < 0.05), differences in WBSF (4.1 vs. 3.9 kg) between cooking methods accounted for less than 5% of the total variation in WBSF. In Exp. 2, the correlation of SSF (r = -0.72; P < 0.001) with trained sensory panel tenderness ratings was slightly stronger than the correlation of WBSF (r = -0.66; P < 0.001) with trained sensory panel tenderness ratings, indicating that the two methods had a similar ability to predict tenderness ratings. In Exp. 3, duplicate samples from 372 carcasses at 2 and 10 d postmortem were obtained, cooked with BG, and SSF was determined. The repeatability of SSF was 0.90, which is comparable to repeatability estimates for beef and lamb. Use of BG cookery and SSF could facilitate the collection of accurate pork longissimus tenderness data. Time and labor savings associated with BG cookery and the SSF technique should help to decrease research costs. C1 USDA ARS, Roman L Hruska US Meat Anim Res Ctr, Clay Ctr, NE 68933 USA.

In the first two experiments, 24 crossbred steers were used to determine the effects of different oral amounts of 1,25-(OH)(2) D-3 (Exp. 1; n = 12) and 25-OH D-3 (Exp. 2; n 12) on plasma Ca2+ concentrations. In the third experiment, crossbred steers were allotted randomly to p one of four treatments: 1) control placebo (n = 7); 2) 5 x 10(6) IU of vitamin D-3/d (n = 9) for 9 d and harvested 2 d after last treatment; 3) single, 125-mg dose of 25OH D-3 (n = 8) 4 d before harvest; or 4) single, 500-mug dose of 1,25-(OH)(2) D-3 (n = 9) 3 d before harvest. The LD and SM steaks from each animal were aged for 8, 14, or 21 d, whereas steaks from the IF were aged for 14 or 21 d. All steaks were analyzed for tenderness by Warner-Bratzler shear force and for troponin-T degradation by Western blot analysis. Supplementing steers with vitamin D-3 increased (P < 0.01) the concentration of vitamin D-3 and 25-OH D-3 in all muscles sampled. Feeding steers 25-OH D-3 increased (P < 0.05) the concentration of 25-OH D-3 in meat, but to an amount less than half that of cattle treated with vitamin D-3. Supplemental 1,25-(OH)(2) D-3 did not affect (P < 0.10) shear force values; however, there was a trend (P < 0. 10) for supplemental vitamin D-3 and 25-OH D-3 to produce LD steaks with lower shear values after 8 and 14 d of aging, and lower (P < 0. 10) shear force values for the SM aged for 21 d. Analysis of Western blots indicated that LD steaks from cattle supplemented with vitamin D-3 and 25-OH D-3 had greater (P < 0.05) troponin-T degradation. Antemortem supplementation of 25-OH D-3 seems to increase postmortem proteolysis and tenderness in the LD and SM without depositing large concentrations of residual vitamin D-3 and its metabolite 25-OH D-3.

Heifers were estrually synchronized before initiation of supplementation. Supplement was individually fed daily for 30 to 32 d, at which time heifers were slaughtered (d 12 to 14 of the estrous cycle) and tissues collected. Heifers were fed a basal diet of sudan grass hay (6.0% CP) ad libitum. On d 28 of supplementation (d 10 of the estrous cycle), no differences were observed (P > 0.10) in serum insulin or IGF-I among treatments. At slaughter (d 10 to 12 of the estrous cycle), treatments did not influence corpus luteum weight, cerebral spinal fluid leptin, or IGFBP; serum estradiol-17beta, progesterone, leptin, IGF-I, and IGFBP; or anterior pituitary content of IGFBP (P > 0.10). Follicular fluid IGFBP-2 and IGFBP-4 were greater in high-UIP heifers than low- or mid-UIP heifers on d 12 to 14 of the estrous cycle (P < 0.05). Basal serum LH concentrations and LH area under the curve (every 15 min for 240 min) did not differ (P > 0.10) following 28 d of supplementation (d 10 of the estrous cycle); however, basal serum FSH concentrations were greater (P = 0.06) in low- and mid- vs. high-UIP heifers (5.2 and 5.2 vs. 4.6 ng/mL, respectively), and FSH area under the curve was greater (P = 0.03) in low- vs. high-UIP heifers. At slaughter (d 12 to 14 of the estrous cycle), anterior pituitary LH and FSH content and steady-state mRNA encoding alpha, LHbeta, and GnRH receptor did not differ (P > 0.10) among treatments. However, FSHbeta mRNA was increased approximately twofold (P = 0.03) in mid vs. low UIP. In summary, low and mid levels of UIP supplements fed to estrous cycling beef heifers seemed to enhance pituitary expression and/or secretion of FSH relative to high levels of UIP. Moreover, high-UIP supplementation was associated with increased low-molecular-weight IGFBP compared with supplementation of low and mid levels of UIP. These data suggest that differing levels of UIP supplementation may alter pituitary and ovarian function, thereby influencing reproductive performance in beef heifers.

X-radiography was used to analyse nests and revealed that 20-50% of the bee cells contained so-called 'pollen balls', a term commonly used in the USA to indicate cells that are provisioned but lack healthy eggs or developing larvae. Dissection of these cells showed that most contained pollen-nectar provisions with collapsed eggs or early, pre-defecating larvae, and a moderate proportion of them had a provision onto which no egg had been laid. Other cells contained incomplete or no provisions along with older dead larvae, beetle larvae and their faeces, or saprophytic fungi (as hyphae). Most provisions were at least somewhat moist, with 25% being very dry. A significant difference in the moisture condition and in the proportions of cell content categories was found among the bee populations examined. These results help direct future studies into understanding why bee cells are provisioned with nectar and pollen but fail to produce mature larvae, and why there are differences in the types of failure between commercial populations. X-ray analysis is inadequate for determining the true moisture condition and content of pollen ball cells. The use of the term pollen ball should be reserved for categorizing data from X-rays of bee cells, but because of its ambiguous nature should not be used to implicate bee mortality.

It has been studied for activities against human and food-born pathogens. In this study the antimicrobial activity of allicin (Allisure(TM) liquid) was tested against a number of bacterial and fungal pathogens (Paenibacillus larvae larvae, P. I. pulvifaciens, Ascosphaera apis and Ascosphaera aggregata) associated with social (Apis mellifera) and solitary bees. The minimum inhibitory concentrations (MIC) of allicin were determined using a broth microdilution method in the range of 1000 ppm to 25 ppm. Allicin liquid showed activity against gram-positive bacterial isolates (MIC 350 ppm) and fungal isolates (MIC 250 ppm). The antimicrobial activity of allicin was also tested in an agar diffusion test using 250 mug of allicin per disk. Bacterial isolates (P. I. pulvifaciens and P. I. larvae) were associated with zones of inhibition in the range of 24-26 mm and 45-50 mm, respectively. The fungal isolates were associated with zones of inhibition in the range of 31-35 mm (A. apis) and 35-37 mm (A. aggregata). The macrolide class antibiotic tylosin (Tylan(R)50, Elanco Inc., IN) was used as a control in both the MIC assay and in the agar diffusion test. The data from this study point to the potential of allicin to inhibit growth of bee pathogens and reduce occurrence of at least two major bee diseases.

Residues were isolated from diluted honey samples by solid-phase extraction followed by quantification using high performance liquid chromatography. Oasis HLB cartridge isolation allowed the concentration of tylosin and desmycosin to be determined separately on the same sample. Oasis MCX extraction gave a single compound (apparently desmycosin dimethyl acetal) from both tylosin and desmycosin, with HPLC peak area proportional to the sum of the two. Tylosin converted to desmycosin with a half-life of approximately 4 months at 34 degreesC. The desmycosin seemed to be quite stable in honey, and the sum of the two antibiotics, determined by either method, decreased only slightly over 9 months. Use of tylosin for treatment of American foulbrood requires caution to prevent persistent residues in honey. C1 USDA ARS, Bee Res Lab, Beltsville, MD 20705 USA.

Two experiments were conducted in Baton Rouge, Louisiana, USA, one in winter (19 colonies) and one in summer (22 colonies). In both experiments, we established uniform colonies of honey bees by subdividing 30 kg of mite-infested bees. Each colony began with about 11 000 bees, no brood, and uniform populations of mites (127 and 480 mites per colony in winter and summer, respectively). The summer test included a third treatment (8 colonies) where a wooden tray (5 cm deep) closed the space beneath a screen floor. After the first 20 days of the experiments, when no adult bees or mites had yet been produced in any of the colonies, the treatments showed no differences in brood production, honey consumption, or survival of adult bees. At nine weeks, colonies with screen floors had fewer mites, a lower percentage of their mite population residing in brood cells (open screen only), and more cells of capped brood. These results suggest that colonies with open-screen floors may hold back the growth of mite populations by decreasing the rate at which mites invade brood cells.

The nine body parts selected for analysis were: proboscis, antenna, forewing, hindwing, hind leg, the third and sixth sternites, and the third and fourth tergites. Twenty-two characters, consisting of widths, lengths or angles, were measured. Factor analysis sorted 14 characters of worker bees into four factors: (Factor 1) characters associated with size, hind leg and antenna; (Factor 2) length of wing venation and forewing; (Factor 3) number of hamuli and venation angle 37; and (Factor 4) venation angle 34. The results of factor and cluster analyses using the 22 characters revealed that the A. florea of Thailand are distributed as one group. Four characters (forewing radial cell length, metatarsus length, 3rd sternite length and antenna length) can be used to separate by Student-Newman-Keuls Statistics the A. florea of Samui and Pha-ngan Islands from the mainland.

Young honey bee larvae were transferred into beeswax cups containing known concentrations (0 to 1000 mg/kg) of coumaphos. The cups with larvae were placed in queenless colonies for rearing and 10 days later acceptance was determined by recording mature queen cells. The queen cells were placed in small mating colonies for 21 days, when the queens were collected after being rated for commercial acceptability. The queens were then either introduced to production colonies and monitored for six months or dissected to determine mating success. All but one queen failed to develop at 1000 mg/kg of coumaphos, and greater than 50% of cells were rejected at 100 mg/kg coumaphos. The queens that were reared were lighter in weight as pre-emergence pupae. The effects on other characters related to queen performance are discussed. The presence of coumaphos in queen rearing cells can reduce the number of queens still functioning in colonies at six months by as much as 75%. C1 USDA ARS, Bee Res Lab, Beltsville, MD 20705 USA.

However, queen producers that might use stored semen to preserve breeder stock would want to rear daughter queens throughout a season, longer than these experimental queens were observed. To determine how long queens inseminated with low viability semen continue to produce worker brood, sister queens were inseminated with various mixtures of fresh and freeze-killed semen, or were allowed to mate naturally. Colonies were evaluated for area of comb with all stages of brood, the percentage of worker vs. drone offspring in sealed brood, and the number of empty cells in a representative area of sealed brood once a month for 5-6 months, at midwinter, and again the following spring. One queen of 22 queens inseminated with 75% or more fresh semen became a partial drone layer by mid winter, only two of the 21 queens inseminated with half fresh semen ran out of sperm, but 3 of 5 of queens with 25% fresh semen were laying some proportion of unfertilized eggs. Preserved semen that has 50% or better viable sperm can be used to inseminate queens that will function as well as a fully mated queen for at least one season, such that a breeder could rear many daughter queens and incorporate desirable genotypes into a breeding programme.

Methods and Results: Inhibitory effect of various concentrations of gossypol on the growth of E. ictaluri was determined. Bacterial recovery was performed by preincubation of bacteria in medium containing various concentrations of gossypol and subsequent activation of bacteria by inoculating on gossypol-free plates. Concentrations of racemic gossypol, (+)-gossypol and (-)-gossypol of 1.5 mug ml(-1) or higher significantly reduced the number of bacterial colonies compared with that of the control. The growth of E. ictaluri was completely inhibited on agar plates supplemented with 3 mug ml(-1), regardless of the forms of gossypol. The inhibitory effect of (+)-gossypol was higher than that of (-)-gossypol or gossypol-acetic acid. Recovery of E. ictaluri was <50% for all three forms of gossypol at concentrations of 5 mug ml(-1). Bacterial recovery remained relatively constant (6.5%) at gossypol concentrations from 10 to 100 mug ml(-1). Complete killing of E. ictaluri was not reached at gossypol levels up to 100 mug ml(-1). Conclusion: Gossypol-acetic acid, and (+)- and (-)-optical isomers have anti-bacterial effect against E. ictaluri. The results suggest the action is bacteriostatic rather than bactericidal. Significance and Impact of the Study: The therapeutic effect of gossypol against E. ictaluri may be useful in controlling enteric septicaemia of catfish.

Thirty Fl. columnare cultures isolated from different fish species and geographical origins as well as reference strains were included in the study. Fifteen isolates belonged to genomovar I while eleven were ascribed to genomovar II. Analysis of the ISR sequence confirmed the genetic differences between both genomovars but revealed a higher diversity among genomovar I isolates. The maximum resolution was provided by AFLP(R) fingerprinting, as up to 22 AFLP profiles could be defined within the species. Conclusions: We confirmed the division of Fl. columnare isolates from cultured fish into different genogroups. We showed that both genomovars I and II are present in channel catfish from the US. We described a unique genetic group represented by four Fl. columnare isolates from tilapia in Brazil which appears to be related to both genomovars. We were able to further subdivide the species by analysing the ISR. Finally, the use of AFLP(R) allowed us to fingerprint the species at clone level without losing the higher genetic hierarchy of genomovar division. Significance and Impact of the Study: This paper reports on an extensive assessment of the use of molecular tools for the study of the epidemiology of the fish pathogen Fl. columnare.

Methods and Results: Waste slurries (faeces : urine : water, 50 : 35 : 15) were blended with and without additives and aliquoted to triplicate 1-l flasks. Faecal coliforms were eliminated in cattle and swine waste slurries within 1 or 2 days with additions of eugenol at 10.05 mm (0.15%) and 16.75 mm (0.25%). At these concentrations volatile fatty acids (VFA) were reduced ca 70 and 50% in cattle and swine waste, respectively, over 6-8 weeks. Additionally, in cattle waste, eugenol stimulated the accumulation of lactate (>180 mm) when compared with thymol treatment (20 mm lactate). In swine waste, lactate accumulation did not occur without additives; eugenol and thymol stimulated lactate accumulation to concentrations of 22 and 32 mm, respectively. Conclusions: Eugenol added to cattle waste may be more beneficial than thymol because not only does it effectively control faecal coliforms and odour (VFA production), it also stimulates lactate accumulation. This in turn, causes the pH to drop more rapidly, further inhibiting microbial activity and nutrient emissions. Significance and Impact of the Study: Plant essential oils have the potential to solve some of the environmental problems associated with consolidated animal feeding operations. Thymol and eugenol reduce fermentative activity, thus, have the potential to reduce emissions of greenhouse gases and odour, and curtail transmission of pathogens in cattle and swine wastes.

Methods and Results: We disrupted A. parasiticus Delta12-oleic acid desaturase gene (odeA) responsible for the conversion of oleic acid to linoleic acid. We examined conidiation and sclerotial development of SRRC 2043 and three isogenic mutant strains deleted for the odeA gene (DeltaodeA), either with or without supplementing linoleic acid, on one complex potato dextrose agar (PDA) medium and on two defined media: nitrate-containing Czapek agar (CZ) and Cove's ammonium medium (CVN). The DeltaodeA mutants produced less conidia than the parental strain on all media. Linoleic acid supplementation ( as sodium linoleate at 0.3 and 1.2 mg ml(-1)) restored the DeltaodeA conidial production comparable to or exceeding the unsupplemented parental level, and the effect was medium dependent, with the highest increase on CVN and the least on PDA. SRRC 2043 and the DeltaodeA mutants were unable to produce sclerotia on CVN. On unsupplemented PDA and CZ, DodeA sclerotial mass was comparable to that of SRRC 2043, but sclerotial number increased significantly to two- to threefold. Supplementing linoleic acid to media, in general, tended to decrease wild type and DeltaodeA sclerotial mass and sclerotial number. Conclusions: Linoleic acid stimulates conidial production but has an inhibitory effect on sclerotial development. The relationship between the two processes in A. parasiticus is complex and affected by multiple factors, such as fatty acid composition and nitrogen source. Significance and Impact of Study: Conditions that promote sclerotial development differ from those required to promote maximum conidial production. Manipulation of content and availability of linoleic acid at different fungal growth phases might optimize conidial and sclerotial production hence increasing the efficacy of biocompetitive Aspergillus species.

These fungi are common postharvest decay pathogens of fresh grapes and other produce. Sanitation of produce reduces postharvest losses caused by these and other pathogens. Methods and Results: Spores of the fungi were exposed to solutions containing up to 30% (v/v) ethanol at 25-50degreesC for 30 s, then their survival was determined by germination on semisolid media. Logistical, second-order surface-response models were prepared for each fungus. Subinhibitory ethanol concentrations at ambient temperatures became inhibitory when heated at temperatures much lower than those that cause thermal destruction of the spores by water alone. At 40degreesC, the estimated ethanol concentrations that inhibited the germination of 50% (LD50) of the spores of B. cinerea, A. alternata, A. niger and R. stolonifer were 9.7, 13.5, 19.6 and 20.6%, respectively. Conclusions: Ethanol and heat combinations were synergistic. Control of spores of these fungi could be accomplished with much lower temperatures and ethanol concentrations when combined compared with either used alone. Botrytis cinerea and A. alternata were less resistant to the combination than A. niger or R. stolonifer. C1 ARS, USDA, San Joaquin Valley Agr Sci Ctr, Parlier, CA 93648 USA.

Royle] occur in the United States, a dioecious type centered in the southeast and a monoecious type in the central Atlantic and northeastern states. Ecosystem managers need tools to distinguish the types as the ranges of each type expand and begin to overlap. A molecular tool using the randomly amplified polymorphic DNA (RAPD) procedure is available but its use is limited by a need for reference samples. We describe an alternative molecular tool which uses "universal primers" to sequence the trnL intron and trnL-F intergenic spacer of the chloroplast genome. This sequence yields three differences between the biotypes (two gaps and one single nucleotide polymorphism). A primer has been designed which ends in a gap that shows up only in the dioecious plant. A polymerase chain reaction (PCR) using this primer produces a product for the monoecious but not the dioecious plant. C1 USDA ARS, Ft Lauderdale, FL 33314 USA.

Solms), is a serious problem in the Sacramento Delta. Two weevil species (Neochetina bruchi Hustache and N. eichhorniae Warner) have been introduced as biological control agents. Factors such as weather, disease, predators, and plant quality affect growth and reproduction of insect herbivores. The purpose of this study was to test the hypothesis that nitrogen (N) in the tissue of waterhyacinth was not sufficient to support weevil growth and reproduction. Waterhyacinth at a site in the Delta (Whiskey Slough) were sampled at 2- to 3-week intervals in 1995, 1996, and 1997. Lamina samples were analyzed for tissue C and N. Tissue C varied less than either tissue N or the C:N ratio. Tissue N was greatest in the leaf lamina, followed by stem bases, and leaf petioles. Lamina tissue N was higher in spring and somewhat reduced in late summer and winter. The lamina C:N ratio was generally <15 after mid-May. Comparing tissue N levels for Delta waterhyacinth with a previous study relating weevil growth to tissue N indicates that tissue N should not limit growth and reproduction of either weevil species during spring and summer. Because it grows better on plants with high N content and because it has a greater impact on the growth of high N plants, N. bruchi may be a more effective biological control agent in the Sacramento Delta.

Systemic administration of kaliotoxin abrogated the bone resorption in conjunction with decreased RANKL mRNA expression by T-cells in gingival tissue. This study suggests a plausible therapeutic approach for inflammatory bone resorption by targeting Kv1.3. Introduction: Kv1.3 is a critical potassium channel to counterbalance calcium influx at T-cell receptor activation. It is not known if Kv1.3 also regulates RANKL expression by antigen-activated T-cells, and consequently affects in vivo bone resorption mediated by activated T-cells. Materials and Methods: Actinobacillus actinomycetemcomitans 29-kDa outer membrane protein-specific Th1-clone cells were used to evaluate the expression of Kv1.3 (using reverse transcriptase-polymerase chain reaction [RT-PCR] and Western blot analyses) and the effects of the potassium channel blocker kaliotoxin (0-100 nM) on T-cell activation parameters ([H-3]thymidine incorporation assays and ELISA) and expression of RANKL and osteoprotegerin (OPG; flow cytometry, Western blot, and RT-PCR analyses). A rat periodontal disease model based on the adoptive transfer of activated 29-kDa outer membrane protein-specific Th1 clone cells was used to analyze the effects of kaliotoxin in T-cell-mediated alveolar bone resorption and RANKL and OPG mRNA expression by gingival T-cells. Stimulated 29-kDa outer membrane protein-specific Th1 clone cells were transferred intravenously on day 0 to all animals used in the study (n = 7 animals per group). Ten micrograms of kaliotoxin were injected subcutaneously twice per day on days 0, 1, 2, and 3, after adoptive transfer of the T-cells. The control group of rats was injected with saline as placebo on the same days as injections for the kaliotoxin-treated group. The MOCP-5 osteoclast precursor cell line was used in co-culture studies with fixed 29-kDa outer membrane protein-specific Th1-clone cells to measure T-cell-derived RANKL-mediated effects on osteoclastogenesis and resorption pit formation assays in vitro. Statistical significance was evaluated by Student's t-test. Results: Kaliotoxin decreased T-cell activation parameters of 29-kDa outer membrane protein-specific Th1 clone cells in vitro and in vivo. Most importantly, kaliotoxin administration resulted in an 84% decrease of the bone resorption induced in the saline-treated control group. T-cells recovered from the gingival tissue of kaliotoxin-treated rats displayed lower ratios of RANKL and OPG mRNA expression than those recovered from the control group. The ratio of RANKL and osteoprotegerin protein expression and induction of RANKL-dependent osteoclastogenesis by the activated T-cells were also markedly decreased after kaliotoxin treatments in vitro. Conclusion: The use of kaliotoxin or other means to block Kv1.3 may constitute a potential intervention therapy to prevent alveolar bone loss in periodontal disease.

Previous work indicates that sorgoleone is produced in living root hairs. We have developed a mist system that resulted in abundant production of root hairs exuding sorgoleone and a mat system that significantly inhibited root hair development and consequently sorgoleone production. Applying Ag+ ( an ethylene action inhibitor) at 1.2 mM to the seedlings grown in the mist system also inhibited root hair formation and elongation. Hypoxic conditions in the mist system did not result in the inhibition of root hair growth as compared to the standard air atmosphere (20.8% O-2). Applying ethephon (an ethylene-releasing agent) at 0.031 mM to the roots of seedlings grown in the mat system with water running at 1 ml/min reversed the inhibition of root hair development by water movement. These results indicate that either water movement or ethylene can be utilized to manipulate root hair development and sorgoleone production in sorghum seedlings. It is hypothesized that water movement reduced the local ethylene concentration on the root surface and consequently inhibited root hair development of sorghum seedlings grown in the mat system.

However, because of genetic similarity to other mycobacteria comprising the M. avium complex, no such antigens have been found. Through a comparative genomics approach, 21 potential coding sequences of M. avium subsp. paratuberculosis that are not represented in any other mycobacterial species tested (n = 9) were previously identified (J. P. Bannantine, E. Baechler, Q. Zhang, L. Li, and V. Kapur, J. Clin. Microbiol. 40:1303-1310, 2002). Here we describe the cloning, heterologous expression, and antigenic analysis of these M. avium subsp. paratuberculosis-specific sequences in Escherichia coli. Nucleotide sequences representing each unique predicted coding region were amplified and cloned into two different E. coli expression vectors encoding polyhistidine or maltose binding protein (MBP) affinity purification tags. All 21 of the MBP fusion proteins were successfully purified under denaturing conditions and were evaluated in immunoblotting studies with sera from rabbits and mice immunized with M. avium subsp. paratuberculosis. These studies showed that 5 of the 21 gene products are produced by M. avium subsp. paratuberculosis and are antigenic. Immunoblot analysis with a panel of sera from 9 healthy cattle and 10 cattle with clinical disease shows that the same five M. avium subsp. paratuberculosis proteins are also detected within the context of infection. Collectively, these studies have used a genomic approach to identify novel M. avium subsp. paratuberculosis antigens that are not present in any other mycobacteria. These findings may have a major impact on improved diagnostics for Johne's disease. C1 USDA ARS, Natl Anim Dis Ctr, Ames, IA 50010 USA. Univ Minnesota, Dept Microbiol, Minneapolis, MN 55488 USA.

The assay uses a single-tube protocol with fluorogenic hydrolysis probes. Oligonucleotide primers and probes were designed to detect sequences from a conserved region of the matrix protein (M) gene that recognized a diverse set (n = 44) of APMV-1 isolates. A second primer-probe set was targeted to sequences in the fusion protein (F) gene that code for the cleavage site and detect potentially virulent NDV isolates. A third set, also directed against the M gene, was specific for the North American (N.A.) pre-1960 genotype that includes the common vaccine strains used in commercial poultry in the United States. The APMV-1 M gene, N.A. pre-1960 M gene, and F gene probe sets were capable of detecting approximately 10(3), 10(2), and 10(4) genome copies, respectively, with in vitro-transcribed RNA. Both M gene assays could detect approximately 10(1) 50% egg infective doses (EID50), and the F gene assay could detect approximately 10(3) EID50. The RRT-PCR test was used to examine clinical samples from chickens experimentally infected with the NDV strain responsible for a recent epizootic in the southwestern United States. Overall, a positive correlation was obtained between the RRT-PCR results and virus isolation for NDV from clinical samples. C1 USDA ARS, SE Poultry Res Lab, Athens, GA 30605 USA.

Here it was tested whether embryonic resistance to heat shock occurs for a thermotolerant breed of different genetic origin than the Brahman. In particular, the thermal sensitivity of in vitro produced embryos of the Romosinuano, a Bos taurus, Criollo-derived breed, was compared to that for in vitro produced Brahman and Angus embryos. At d 4 after insemination, embryos greater than or equal to8 cells were randomly assigned to control (38.5degreesC) or heat shock (41degreesC for 6 h) treatments. Heat shock reduced the proportion of embryos that developed to the blastocyst stage on d 8 after insemination. At 38.5degreesC, there were no significant differences in development between breeds. Among embryos exposed to 41degreesC, however, development was lower for Angus embryos than for Brahman and Romosinuano embryos. Furthermore, an Angus vs. ( Brahman + Romosinuano) x temperature interaction occurred because heat shock reduced development more in Angus (30.3 +/- 4.6% at 38.5degreesC vs. 4.9 +/- 4.6% at 41degreesC) than in Brahman (25.1 +/- 4.6% vs. 13.6 +/- 4.6%) and Romosinuano (28.3 +/- 4.1% vs. 17.5 +/- 4.1%). Results demonstrate that embryos from Brahman and Romosinuano breeds are more resistant to elevated temperature than embryos from Angus. Thus, the process of adaptation of Brahman and Romosinuano breeds to hot environments resulted in both cases in selection of genes controlling thermotolerance at the cellular level.

Forty primiparous (86 +/- 39 d in milk) and 40 multiparous (88 +/- 30 d in milk) cows were fed a total mixed ration containing 13% ( dry matter basis) DWCS or LWCS in two blocks of 112 d (n = 53 and 27, respectively). Other total mixed ration ingredients ( dry matter basis) were corn silage (28.1%), alfalfa silage (23%), high moisture shelled corn (27.8%), soybean meal (1.8%), expeller soybean meal ( 1.8%), blood meal (2%), and mineral-vitamin supplements (2.5%). Dry matter intake and milk yield were measured daily and milk composition every other week. Fecal grab samples were taken during wk 3 and 13 of each block to estimate excretion of intact whole cottonseeds. Milk yield, 3.5% fat-corrected milk, energy-corrected milk, milk composition and dry matter intake were not affected by whole cottonseed source. Body condition score tended to increase more with DWCS (0.22 vs. 0.11) for primiparous cows, although this was not reflected in body weight change. Dry matter digestibilities, based on indigestible ADF, were 63.5 and 64.8% for the DWCS and LWCS diets. It was calculated that 2.5 and 1.5% of the consumed seeds were excreted as whole cottonseeds in feces with the DWCS and LWCS diets, respectively. Although statistically significant, treatment differences in the proportion of intact seeds in the fecal DM would have little nutritional consequence. Mechanically delinted WCS performed as well as LWCS for all of the cow performance and milk composition variables measured. C1 USDA ARS, US Dairy Forage Res Ctr, Madison, WI 53706 USA.

Diets containing 0.37 or 0.57% P (dry basis) were fed to Holstein cows for the first 165 d of lactation, and occasionally longer until cows were confirmed pregnant approximately 60 d after insemination. At calving, cows were randomly assigned to experimental diets. The number of cows completing a minimum of 165 d of lactation was 123 for the 0.37 and 124 for the 0.57% P groups. Cows were housed in a stanchion barn and fed one of two transition diets, each formulated to contain one of the P treatments for the first 3 wk of lactation, and then cows were moved to a free-stall barn where the experimental diets were group fed. Milk production, milk fat, and milk protein averaged 35.1 kg/d, 3.92%, and 2.90% for the 0.37% P diet, and 34.9 kg/d, 3.98%, and 2.91% for the 0.57% P diet. None of these measures were different between treatments. Blood serum P concentrations on d 50 and 100 of lactation averaged 6.1 and 6.2 mg/dL for the 0.37% P diet, and 6.8 and 6.9 mg/dL for the 0.57% P diet. No treatment differences were detected in milk production, cow health, or body condition score. C1 Univ Wisconsin, Dept Dairy Sci, Madison, WI 53706 USA.

At calving, Holstein cows were randomly assigned to 1 of 2 dietary treatments (n = 134 for 0.37% P and n = 133 for 0.57% P). Cows were fitted with a radiotelemetric transmitter ( 50 d in milk [ DIM]) to record mounting activity during estrus and bred to natural estrus from 50 to 100 DIM, then to synchronized estrus (Ovsynch protocol) after 100 DIM. Weekly ultrasonography was performed from 50 DIM until pregnancy was diagnosed (similar to 30 d after artificial insemination). Pregnancy was confirmed approximately 60 d after artificial insemination ( artificial insemination). Weekly blood samples were analyzed for progesterone concentrations. Days to first increase (> 1 ng/ml) in progesterone, days to first estrus detected by radiotelemetry, days to first service detected by herd personnel, and conception rate at first service did not differ between the recommended and excess P groups, respectively. Similarly, conception rate at 30 d, days open, pregnancies lost from 30 to 60 d, multiple ovulation rate, and the incidence of anovulatory condition at 71 DIM did not differ between these groups. The mean duration of estrus was 8.7 +/- 0.5 and 8.7 +/- 0.7 h, and the average number of mounts per estrus was 7.4 +/- 0.5 and 7.8 +/- 0.5 for a total mounting time during estrus of 25.8 +/- 1.8 and 24.5 +/- 1.6 s for cows fed the recommended and excess P diet, respectively.

By using polymerase chain reaction (PCR) and DNA sequencing, we demonstrated clear molecular difference between these two strains. DNA markers that are specific for the Barn strain were developed, and PCR-generated DNA fragments were cloned and sequenced. Two DNA fragments unique to the Barn strain contained 365 and 584 nucleotides. A pair of specific primers was designed from each fragment. PCR-amplification of the DNA from individual wasps generated fragments of the expected sizes only in the Barn strain. Studies conducted on F1 and F2 hybrids produced from crossing and backcrossing between resistant and susceptible strains indicated that these DNA markers are located on mitochondria and inherited exclusively maternally. Probes developed from these fragments may be used in assessing genetic information of natural populations and in studies on physiological or biochemical differences between the strains of this beneficial insect.

Allotropa n. sp. and Zarhopalus debarri Sun were the primary endoparasitoids emerging from O. acuta. Adult abundance varied seasonally, with Allotropa n. sp. numbers peaking in June and Z debarri in September. Parasitism rates of female O. acuta exceeded 60% at one site and ranged from 24 to 29% at the other site. The adult female was the preferred host stage for parasitism (76%), though Allotropa n. sp. and the endoparasitoid Acerophagus coccois E. Smith occasionally utilized second and third instar females as hosts. These two species exhibited gregarious parasitism, with up to 5 Allotropa n. sp. or 4 A. coccois emerging from a single host. Adult longevity of female and male Z debarri averaged 6.4 and 5.3 days, respectively, and access to a food source usually increased adult lifespan. Female Z debarri contained an average of 119 eggs, compared to 74 eggs per female for Allotropa n. sp.

The potency of PxMNPV could be increased by the addition of certain diaminostilbene disulfonic acid-derived fluorescent brighteners, including Blankophor P167(R) at a concentration of 1%. Other fluorescent brighteners, including Blankophor HRS(R) at 1%, reduced the activity of PxMNPV, though lower concentrations of Blankophor HRS (0.25 to 0.5%) enhanced activity. In contrast, Blankophor HRS at 1% enhanced the nucleopolyhedrovirus; of the celery looper, Anagrapha falcifera (Kirby), (AfMNPV) against the diamondback moth. Similar results were found in the corn earworm, Helicoverpa zea (Boddie), and the beet armyworm, Spodoptera exigua (Hubner), which are also susceptible to both PxMNPV and AfMNPV. Consumption of foliage treated with Blankophor HRS (0.5 to 1.0%) did not differ from that of foliage treated with similar concentrations of Blankophor P167. These results indicate a negative effect of higher concentrations of Blankophor HRS on PxMNPV, rather than on the host insect. C1 ARS, USDA, Insect Biocontrol Lab, Beltsville, MD 20705 USA.

Resistance to cypermethrin increased incrementally from 3.6-fold in the parental strain to 35-fold after 4 rounds of selection. No significant changes were observed in cytochrome P450 content, aldrin epoxidase activity, (alpha-naphthyl acetate hydrolysis (cytosolic fraction), or glutathione S-transferase (CDNB conjugation) activities. Although no significant differences were observed in cypermethrin metabolism, a trend toward greater detoxification among each successive generation was observed. Furthermore, methoxyresorufin O-demethylase activity (often associated with pyrethroid resistance) increased incrementally with each successive selection iteration. The average knockdown time increased incrementally from 37 min (parental strain) to 177 min, and there was a corresponding increase in the kdr allele frequency from 19% to 99% after 4 rounds of selection. The data indicated that kdr-type nerve insensitivity and enhanced metabolism by cytochromes P450 and hydrolases were the principle mechanisms of resistance after selection with cypermethrin.

Because sperm production in sterile insects has been cited as an important component of competitiveness, it was measured in irradiated and unirradiated bugs. Bugs subjected to dosages of 5, 10, 20, and 40 krad (50, 100, 200, and 400 Gy) of gamma-irradiation at approximately 7 d post-eclosion to adulthood produced less sperm than untreated bugs. Sperm production was inversely related to dosage. Sperm counts exceeded 1 million per male in the control group and peaked at approximately 600,000 per male in the 5 krad group at day 21 post-eclosion, at approximately 500,000 per male for the 10 and 20 krad groups between days 17 and 21 post-eclosion, and never exceeded half of the control for the 40 krad group, which suffered high mortality in all three replications. Sperm was not seen in newly-eclosed adults, but accumulations averaged 23,000 in 3-d post-eclosion adults and increased to over 100,000 by day 5. Peak counts of 1.6 million were recorded on day 31 post-eclosion. C1 ARS, USDA, So Insect Management Res Unit, Mississippi State, MS 39762 USA.

Spatial patterns of campsite impact were studied in two subalpine plant communities in the Wind River Mountains, Wyoming, USA (a forest and a meadow). Response to chronic disturbance and recovery from acute disturbance were both assessed. Previously undisturbed sites were camped on at intensities of one and four nights/year, for either one or three consecutive years. Recovery was followed for three years on sites camped on for one year. Percent bare ground, assessed in 49 contiguous I m(2) quadrats, increased with increasing use frequency, particularly on the forest sites. Magnitude of impact varied spatially within campsites, with impact decreasing as distance from the center of the campsite increased. On the more fragile forest sites, this radial impact pattern developed rapidly and remained after three years of recovery. Concentration of camping activities around a centrally located small cooking stove was the apparent cause of this pattern. Maximum variation in magnitude of impact occurred at intermediate levels of campsite use and disturbance. The magnitude, variability and spatial pattern of impact varied with the spatial scale of analysis. Generally, results of these controlled experiments are consistent with earlier studies of campsites and validate the management implications derived from those studies. Even where campers use low-impact techniques, low levels of camping use can cause substantial impact and it is important to concentrate use. On resistant sites, however, it is possible that low levels of use can be sustained with minimal resultant impact. Published by Elsevier Ltd.

Measured data included subsurface drainage flows, NO3-N concentrations and loads in subsurface drainage water, and corn (Zea mays L.) and soybean [Glycine mar (L.) Merr.] yields. The dominant soil within this field was Webster (fine-loamy, mixed, superactive, mesic Typic Endoaquolls) and cropping system was corn-soybean rotation. The model was calibrated with 1992 data and was validated with 1993 to 1997 data. Simulations of subsurface drainage flow closely matched observed data showing model efficiency of 99% (EF = 0.99), and difference (D) of 1% between measured and predicted data. The model simulated NO3-N losses with subsurface drainage water reasonably well with EF = 0.8 and D = 13%. The simulated corn grain yields were in close agreement with measured data with D < 10%. Nitrogen-scenario simulations demonstrated that corn yield response function reached a plateau when N-application rate exceeded 90 kg ha(-1). Fraction of applied N lost with subsurface drainage water varied from 7 to 16% when N-application rate varied from 30 to 180 kg ha-1 after accounting for the nitrate loss with no-fertilizer application. These results indicate that the RZWQM has the potential to simulate the impact of N application rates on corn yields and NO3-N losses with subsurface drainage flows for agricultural fields in central Iowa.

Information is needed on the effects of other (non-IP6) organic ligands (LIGND) on the enzymatic dephosphorylation of IP6, which is a potential source of dissolved orthophosphate P (PO4-P) in the soil-manure-water system. The effects of 1,2-cyclohexane diamino-tetraacetate (CDTA), diethylenetriamine-N,N,N',N",N"-pentaacetate (DTPA), ethyienediamine-N,N,N',N'-tetraacetate (EDTA), oxalate (OXA), and phthalate (PHTH) and LIGND to IP6 molar ratio and charge concentration ratio on IP6 dephosphorylation were studied to determine controlling mechanisms of IP6 persistence in manure. Solution PO4-P concentrations were analyzed by ion chromatography as the phosphomolybdate-ascorbic acid method partly includes IP6-P. Uncomplexed IP6 dephosphorylation by Aspergillus ficuum (Reichardt) Henn. phytase EC 3.1.3.8 at pH 4.5 and 6 is unaffected by the presence of LIGNDs. As the concentrations of Ca2+, Al3+, or Fe3+ increase, dephosphorlylation is reduced. Their inhibitory effect lessens in the presence of LIGNDs, in the following order: CDTA = EDTA > DTPA much greater than OXA greater than or equal to PHTH. Whether CDTA or EDTA is the most effective LIGND depends upon the acidity of the suspension and LIGND charge concentration, reducing the inhibitory effect of polyvalent counterions to the point of promoting the hydrolysis of a manure phytase-hydrolyzable phosphorus (PHP) fraction that is otherwise unavailable. Therefore, ligand-induced changes increase the mobilization and dephosphorylation of complexed organic P, above and beyond the simple dissolution of inorganic phosphates. An analytical method for potentially bioavailable PHP in animal manure should include a LIGND as extracting reagent. Also, potential LIGNDs in an organic carbon-rich dairy wastewater may increase the release of PHP and environmental dispersion of PO4-P.

Identification and quantification of these forms may significantly contribute to effective agricultural P management. Phosphatases catalyze reactions that release orthophosphate (P-i) from P-o compounds. Alkaline phosphatase in tris-HCl buffer (pH 9.0), wheat (Triticum aestivum L.) phytase in potassium acetate buffer (pH 5.0), and nuclease PI in potassium acetate buffer (pH 5.0) can be used to classify and quantify P. in animal manure. Background error associated with different pH and buffer systems is observed. In this study, we improved the enzymatic hydrolysis approach and tested its applicability for investigating P-o in soils, recognizing that soil and manure differ in numerous physicochemical properties. We applied (i) acid phosphatase from potato (Solanum tuberosum L.), (ii) acid phosphatases from both potato and wheat germ, and (iii) both enzymes plus nuclease PI to identify and quantify simple labile monoester P, phytate (myo-inositol hexakis phosphate)-like P, and DNA-like P, respectively, in a single pH/buffer system (100 mM sodium acetate, pH 5.0). This hydrolysis procedure released P-o in sequentially extracted H2O. NaHCO3, and NaOH fractions of swine (Sus scrofa) manure, and of three sandy loam soils. Further refinement of the approach may provide a universal too] for evaluating hydrolyzable P-o from a wide range of sources.

We conducted an incubation study to determine the relative P solubility and bioavailability, referred to as P source coefficients (PSCs), for organic P sources, which are typically land-applied in the Mid-Atlantic USA. Nine organic and one inorganic (KH2PO4) P amendments were applied to an Evesboro loamy sand (mesic, coated Typic Quartzipsamments) at a rate of 60 mg P kg(-1) and incubated for 8 wk with subsamples analyzed at 2 and 8 wk. There was an increase in Mehlich-3 P (M3-P), water-soluble P (WS-P), iron-oxide strip extractable P (FeO-P), and Mehlich-3 P saturation ratio (M3-PSR) with P additions, which varied by P source. The trend of relative extractable WS-P, FeO-P, and M3-P generally followed the pattern: inorganic P > liquid and deep pit manures > manures and biosolids treated with metal salts or composted. We found significant differences in the availability of P from varying organic P sources. The use of PSCs may be beneficial when determining the risk of P losses from land application of manures and other organic P sources and could be used in risk assessments such as a P site index. These PSCs may also be useful for determining P application rates when organic P sources are applied to P deficient soils for use as a fertilizer source.

(TC), the primary grain used in swine (Sus scrofa) diets, stores a majority of its P as phytate, which is largely unavailable for digestion by nonruminant animals. Low-phytate corn (LPC) contains similar amounts of total P but a smaller percentage of P as phytate. When fed to swine, LPC increases P utilization and reduces P content of manure. While differences in P content between manure from animals fed TC and LPC diets have been documented, solubility and lability of manure P have not been compared. Manure P was characterized in manure from swine fed either LPC or TC diets in 2000 and 2001. Total P was lower (20 vs. 34 g kg(-1)) and N to P ratio was higher (4.5 vs. 3.3) in LPC manure than in TC manure. Manures were sequentially extracted with deionized water, 0.5 M NaHCO3, 0-1 M NaOH, and 1.0 M HCl. Extracts were analyzed for inorganic and total P. Most P (approximately 80%) in the extracts was in the inorganic form. Concentration of P in the water-extractable fraction was lower for LPC manure (10.2 g kg(-1) in 2000 and 9.7 g kg(-1) in 2001) than for TC manure (13.6 g kg(-1) in 2000 and 17.0 g kg(-1) in 2001). Percentage of total P in each extract was in the order of. H2O (60%), HCl (22%), NaHCO3 (12%), NaOH (8%), and residue (<1%). Total P and distribution of P in extracts indicates swine are able to utilize more P contained in LPC feed but the composition of P excreted in LPC manure is similar to TC manure. Solubility, crop availability, and lability of P in LPC manure should be similar to that of TC manure. C1 Univ Nebraska, USDA ARS, Soil & Water Conservat Res Unit, Lincoln, NE 68583 USA.

Our objectives were to determine the long-term (1460 d) DP retention and release characteristics of an in-stream wetland, and to evaluate how these characteristics respond to flooding, draining, and changes in DP concentrations. The studied in-stream wetland drains an agriculturally intensive subwatershed in the North Carolina Coastal Plain region. The wetland's DP retention and release characteristics were evaluated by measuring inflow and outflow DP concentrations, DP mass balance, and DP movement across the sediment-water column interface. Phosphorus sorption isotherms were measured to determine the sediment's equilibria P concentration (EPCo), and passive samplers were used to measure sediment pore water DP concentrations. Initially, the in-stream wetland was undersized (0.31 ha) and released 1.5 kg of DP. Increasing the in-stream wetland area to 0.67 ha by flooding resulted in more DP retention (28 kg) and low outflow DP concentrations. Draining the in-stream wetland from 0.67 to 0.33 ha caused the release of stored DP (12.1 kg). Shifts both in sediment pore water DP concentrations and sediment EPCo values corroborate the release of stored DP. Reflooding the wetiand from 0.33 to 0.85 ha caused additional release of stored DP into the outflowing stream (10.9 kg). We conclude that for a time period, this in-stream wetland did provide DP retention. During other time periods, DP was released due to changes in wetland area, rainfall, and DP concentrations.

Amending poultry litter with alum [Al-3(SO4)(2).14H(2)O] has received considerable attention as a method of economically reducing ammonia volatilization in the poultry house and soluble phosphorus in runoff waters. The objective of this study was to characterize the effect of alum on broiler litter decomposition and N dynamics under laboratory conditions. Litter that had been amended with alum in the poultry house after each of the first four of five flock cycles (Experiment I) and litter that had been amended with alum after removal from a poultry house after the third flock cycle (Experiment II) were compared with unamended litter in separate studies. The litters in Experiment I were surface-applied to simulate application to grasslands, while the litters in Experiment II were incorporated to simulate application to conventionally tilled crops. The only statistically significant differences in decomposition due to alum occurred early in Experiment 11 and the differences were small. The only statistically significant differences in net N mineralization, soil inorganic N, and soil NH4+-N in either experiment was found in Experiment I after 70 d of incubation where soil inorganic N was significantly greater for the alum treatment. Thus, alum had little effect on decomposition or N dynamics. Results of many of the studies on litter not amended with alum should be applicable to litters amended with alum to reduce P availability.

This study of Telone C35, a mixture of (Z)- and (E)-1,3-dichloropropene (1,3-D) with chloropicirin (CP), focuses on its emissions, distribution, and persistence in Florida sandy soil in microplots with different soil-water and organic matter carbon (C) content with and without two different plastic film mulches. The addition of CP did not affect the physical behavior of the isomers of 1,3-D. Slower subsurface dispersion and longer residence time of the mixed fumigant occurred at higher water content. An increase in the percent organic. carbon in the soil led to a more rapid decrease for chloropicirin than for 1,3-dichloropene isomers. The use of a virtually impermeable film (VIF) for soil cover provided a more even distribution and longer persistence under all the conditions studied in comparison to polyethylene (PE) film cover or no cover. The conditions of near field capacity water content, low organic matter, and a virtually impermeable film cover yielded optimum conditions for the distribution, emission control, and persistence of Telone C35 in a Florida sandy soil.

The main purpose of this study was to evaluate soil-water partitioning of 1,3-D in two California agricultural soils (Salinas clay loam and Arlington sandy loam). The partition coefficients (K-d and K-f) were determined by directly measuring the concentration of 1,3-D in the solid phase (C-s) and aqueous phase (C-w) after batch equilibration. In the Salinas clay loam, the K-f of cis-1,3-D in adsorption and desorption isotherms was 0.47 and 0.54, respectively, with respective values of 0.39 and 0.49 for trans-1,3-D. This slight hysteric effect suggests that a different range of forces are involved in the adsorption and desorption process. Since n was near unity in the Freundlich equation, the Freundlich isotherms can also be approximated using the liner isotherm. At 25 degreesC, the K-d of the 1,3-D isomers in both soils ranged from 0.46 to 0.56, and the K-oc, (organic matter partition coefficient) ranged from 58 to 70. The relatively low K-d values and a K-oc that falls within the range of 50-150, suggests that 1,3-D is weakly sorbed and highly mobile in these soils. Understanding the sorption behavior of 1,3-D in soil is important when developing fumigation practices to reduce the movement of 1,3-D to the air and groundwater.

This study on surface emissions and subsurface diffusion of 1,3-D in a Florida sandy soil was conducted in field beds with or without plastic covers. After injection of the commercial fumigant Telone II by conventional chisels to field beds at 30 cm depth which were covered with polyethylene film (PE), virtually impermeable film, or no cover (bare), (Z)- and (E)-1,3-D rapidly diffused upward. Twenty hours after injection, majority of (Z)- and (E)-1,3-D had moved upward from 30 cm depth to the layer of 5-20 cm depth. Downward movement of the two isomers in the beds with or without a plastic cover was not significant. (Z)-1,3-D diffused more rapidly than (E)-1,3-D. Virtually impermeable films (VIF) had a good capacity to retain (Z)- and (E)-1,3-D in soil pore air space. Vapor concentrations of the two isomers in the shallow subsurface of the field bed covered with VIF were greater than that in the two beds covered with polyethylene film (PE) or no cover (bare). In addition, VIF cover provided more uniform distribution of (Z)- and (E)-1,3-D in shallow subsurface than PE cover or no cover. Virtually impermeable film also had a better capability to retard surface emissions of the two isomers from soil in field beds than PE cover or no cover.

Soil and soil solution properties influence the adsorption and desorption of Cu by the soil, which in turn determines its plant availability and/or phytotoxicities. Effects of different anion enrichment in the equilibrium solution on Cu adsorption by different soils (pH range of 6.2-9.9) were investigated in this study over a range of Cu concentrations. With Cu concentrations in the range of 0-100 mg L-1 in the equilibration solution, 95-99% of applied Cu was adsorbed by all three soils. The adsorption of Cu was similar regardless of using either 0.01 M CaCl2 or Ca(NO3)(2) as the equilibration solution. When the Cu concentration in the equilibration solution was further increased in the range of 500-2000 mg L-1, the adsorption of Cu decreased from 60 to 24% of applied Cu in two soils with pH 6.2-7.9. In a high pH soil (pH=9.9), the Cu adsorption decreased from 77 to 34%. Addition of incinerated sewage sludge (ISS) to a Palouse silt loam soil (pH = 6.2) increased the Cu adsorption as compared to that by unamended soil. This was, in part, due to an increase in the soil suspension pH with ISS amendment. C1 USDA ARS, Vegetable & Forage Crops Res Unit, Prosser, WA 99350 USA. Savannah State Univ, Savannah, GA USA.

Comparative phylogenetic analysis showed a correspondence between the mosquito host genera and their Amblyospora parasite species. There is a clade of Amblyospora species that infect the Culex host group and a clade of Amblyospora that infect the Aedes/Ochlerotatus group of mosquitoes. Parathelohania species, which infect Anopheles mosquitoes, may be the sister group to the Amblyospora in the same way that the Anopheles mosquitoes are thought to be the sister group to the Culex and Aedes mosquitoes. In addition, by sequence analysis of small subunit rDNA from spores, we identified the alternate copepod host for four species of Amblyospora. Amblyospora species are specific for their primary (mosquito) host and each of these mosquito species serves as host for only one Amblyospora species. On the other hand, a single species of copepod can serve as an intermediate host to several Amblyospora species and some Amblyospora species may be found in more than one copepod host. Intrapredatorus barri, a species within a monotypic genus with Amblyospora-like characteristics, falls well within the Amblyospora clade. The genera Edhazardia and Culicospora, which do not have functional meiospores and do not require an intermediate host, but which do have a lanceolate spore type which is ultrastructurally very similar to the Amblyospora spore type found in the copepod, cluster among the Amblyospora species. In the future, the genus Amblyospora may be redefined to include species without obligate intermediate hosts. Hazardia, Berwaldia, Larssonia, Trichotuzetia, and Gurleya are members of a sister group to the Amblyospora clades infecting mosquitoes, and may be representatives of a large group of aquatic parasites.

TI Quality traits of date palm fruits in a center of origin and center of diversity SO JOURNAL OF FOOD AGRICULTURE & ENVIRONMENT LA English DT Article DE Date palm; Phoenix dactylifera; diversity; fruit quality; Arabian Peninsula AB Multivariate statistical analyses procedures were employed in data reduction of six fruit qualitative traits in addition to economic value and a final score of fruit quality, scored at the "tamr" fruit ripening stage of 203 date palm cultivars grown in 20 ecogeographical regions in six countries in the Arabian Peninsula. Phenotypic diversity indices varied tremendously among (0.885 to 1.122) and within (0.086 to 0.998) countries. These cultivars represent a complex gene pool within which historical movements of germplasm, recent introductions and human selection are shaping their genetic structure. The relatively low amount of variation (49%) explained by the first three principal components, and the portion of total diversity (0.761) partitioned among ecogeographical regions (32%), among populations (45%) and among cultivars (23%) indicate the presence of a highly diverse germplasm among and within countries. Discriminant analysis correctly assigned 55 to 88% of the germplasm to its country of origin; fruit color, ripening and shape provided the basis for this level of discrimination. Anthropogenic factors were reflected on the number of traits forming two-, three- or four-trait log-linear models for each country. However, fruit color, shape, size and ripening and their interactions predominantly reflected differences in consumer preferences in these countries. "Hot spots" were identified in some ecogeographical regions where unique variants of quality traits are found with high frequencies. C1 [Jaradat, A. A.] ARS, USDA, Morris, MN 56267 USA.

Examples of direct linear or non-linear analysis of the spectral bands of hyperspectral images that resulted in more efficient multispectral imaging techniques are given. Various image analysis methods for the detection of defects and/or contaminations on the surfaces of Red Delicious, Golden Delicious, Gala, and Fuji apples are compared. Surface defects/contaminations studied include side rots, bruises, flyspecks, scabs and molds, fungal diseases (such as black pox), and soil contaminations. Differences in spectral responses within the 430-900 nm spectral range are analyzed using monochromatic images and second difference analysis methods for sorting wholesome and contaminated apples. An asymmetric second difference method using a chlorophyll absorption waveband at 685 nm and two bands in the near-infrared region is shown to provide excellent detection of the defective/contaminated portions of apples, independent of the apple color and cultivar. Simple and requiring less computation than other methods such as principal component analysis, the asymmetric second difference method can be easily implemented as a multispectral imaging technique.

The algorithm developed by a hyperspectral imaging system was employed for multispectral image analysis to validate the accuracy of fecal and ingesta detection in real-time poultry processing. A multispectral imaging system could be used effectively for detecting feces (from duodenum, ceca, and colon) and ingesta on the surface of poultry carcasses with the processing time of approximately 251 ms or 3.99 frames/s. The multispectral imaging system developed in this research can be used for real-time, on-line detection of fecal and ingesta contaminant on poultry carcasses. The overall accuracy to identify fecal and ingesta contaminants, was 96.8% and the prediction accuracy to identify each contaminant were 92.4% for duodenum and 98% for ceca, colon, and ingesta with moderate false positives.

Scanning electron micrographs of cross sections of black bean extrudates illustrated the increase in volume expansion, with an increase of sodium bicarbonate (NaHCO3) in the extrudate. This increase in volume expansion is attributed to the increase in air cell size and corresponding decrease in air cell wall thickness with additional concentrations of NaHCO3. The measured increase in diameter and expansion ratio of extrudates with NaHCO3 addition may be explained by the increase in number of air cells within the extrudate and the increase in pores in the gelatinized starch matrix of air cell walls. Extrusion conditions, which involved the use of heat and moisture, provided the necessary conditions for the release of CO2 from NaHCO3 during processing. Expansion ratio increases between the control extrudate, and extrudate with 0.5% NaHCO3 addition were twofold at the node and 1.8-fold at the area between the nodes. Statistical analysis of color data exhibited no significant change in L*, hue or chroma across concentrations of NaHCO3 for nonextruded flours. A simple linear regression adequately described changes in L* and hue for extruded flours. However, a curvilinear relationship was needed to explain changes in chroma versus NaHCO3 for extruded flours, making changes in chroma measurements less easy to interpret. The color data in this study serve as primary information for future establishment of cut-off values of color for the development of an acceptable legume snack.

Boxed pears from both types of packaging were stored in regular atmosphere (RA) storage at 1C for 30 or 90 days. In the second year, pears were packed normally and stored in both RA or controlled atmosphere (CA) storage for 45 or 90 days, or packed in modified atmosphere bags and stored in RA at 1C. After 45 days, normally packed pears from both RA and CA were removed from their initial storage, placed in modified atmosphere bags and returned to RA storage for an additional 45 days. Pears stored in modified atmosphere bags were superior in quality to normally packed pears stored only in RA storage and equal in quality to pears stored in CA for periods of 90 days. The quality of pears held in modified atmosphere bags under CA conditions deteriorated after only short periods of time (<45 days). Pears in modified atmosphere bags should be stored only in RA. Little or no quality advantage was evident if use of modified atmosphere bags was delayed regardless of prior storage type. C1 USDA ARS, Tree Fruit Res Lab, Wenatchee, WA 98801 USA.

Processing conditions can affect the molecular structure of these dietary fibers, which in turn affect quality and properties of the products. In this study, the effect of puffing and jet cooking conditions on changes in the solubility and molecular weight of barley beta-glucans was investigated. Barley flour was processed in a pasta extruder to produce particles similar in size and shape to rice. These particles were puffed at 230, 250 and 270C for 6, 8 and 10s in a rice cake machine. Solubility and molecular weight of barley beta-glucans were determined by using water extracts (25 or 65C). The amount of beta-glucan extracted in water at 25C increased from 41.1% in cakes puffed at 230C/6 s to 69.7% in cakes puffed at 270C/10 s.

We used gluconic acid/sodium gluconate (pK(a) = 3.7) as a noninhibitory buffer to maintain pH at selected values in the absence of other organic acids. This was possible because we found that the inhibitory effects of this acid on E. coli strains at pH 3.1 were independent of acid concentration over a range of 2 to 200 mM. By this method, the lethal effects of acetic acid solutions (100 to 400 mm) at selected pH values between 3.1 and 4.1 were compared with the effects of pH alone (as determined using gluconate buffer). We found D-values were two- to fourfold lower with acetic acid compared with the effect of pH alone for simulated pickle brines in this pH range. Glutamic acid, an amino acid that is known to enhance acid resistance in E. coli and is a component of pickle brines, protected the E. coli strains from the specific effects of acetic acid.

In most cases, a three-phase linear model fit the primary survival curves well (r(2) = 0.97 to 0.99) at all incubation temperatures regardless of model medium, indicating the presence of a resistant subpopulation of C. jejuni that would not be eliminated without thermal processing. Secondary models predicting lag time (LT) and specific death rate (SDR) as functions of temperature were also developed. The Davey and Boltzmann models were identified as appropriate secondary models for LT and SDR, respectively, on the basis of goodness of fit (Boltzmann model, r(2) = 0.96; Davey model, r(2) = 0.93) and prediction bias and accuracy factor tests. The results obtained indicate that C. jejuni can survive well at both refrigeration and ambient temperatures regardless of model medium. Reduced survival of C jejuni, characterized by shorter lag times and faster death rates, was observed both on patties and in broth at ambient temperatures. In addition, the average maximum reduction of C jejuni at 4 to 30degreesC was 1.5 log units regardless of storage temperature or model medium. These findings suggest that C. jejuni found on contaminated poultry products has the potential to survive under conditions that are not permissive for growth and thus could cause foodborne illness if the poultry is not sufficiently cooked.

Individual links were inoculated with about 8.0 log CFU per package of a five-strain mixture of the pathogen, vacuum sealed, and stored at 4degreesC for 3 and 15 days and at -18degreesC for 30 days. Frankfurters formulated with and without 2% added potassium lactate were heated to a surface temperature of 60, 70, 80, or 90degreesC for up to 8 min by submersing the packages in a thermostatically controlled circulating water bath. Surviving bacteria were recovered and counted by rinsing the contents of each package with sterile peptone water and plating this solution directly onto modified Oxford selective agar plates. In general, the results revealed that about a 5-log unit reduction was achieved by reheating to a surface temperature of 70degreesC for about 2 min or 80 or 90degreesC for about 0.6 min regardless of storage conditions or formulation. Product formulation did not appreciably affect the viability of the pathogen after heating; there was no appreciable difference in the number of cells surviving the heat treatment in product prepared with or without potassium lactate. These findings can be used to establish reheating guidelines for consumers to ensure that frankfurters, which may become contaminated with low levels of L. monocytogenes prior to packaging and after unpackaging, are adequately reheated prior to consumption.

To identify this nonprotein amino acid from seed extract and sprout water, a qualitative micro-thin-layer chromatography method was developed. Successful separation and identification was achieved using microsilica plates, a 70:30 ethyl alcohol-water solvent system, and 1% ammonium disodium pentacyanoammineferrate II for color development. This quick method was used to identify canavanine (sensitivity 50 mug) from irradiated and nonirradiated alfalfa and clover seed extracts and alfalfa sprout water. Broccoli and radish seed extracts were negative for canavanine. This simple method is useful to track the release and decrease of canavanine in the sprout water.

The preharvest drench was not effective in controlling the development of SS in fruit returned to RA storage following 7 months CA storage. Application of a 1750-p.p.m. ethoxyquin line spray (without TBZ) following 5 months CA storage effectively extended the control of SS to 2 months under RA conditions. The 1750 p.p.m. ethoxyquin line spray was effective in controlling SS for I month RA storage following an additional 2 months CA storage period. This represents a 36% reduction in the amount of ethoxyquin currently used on fruit stored for short periods of time. Minor, noncommercial amounts of pithy brown core (PBC) developed during storage, demonstrating that 1% O-2 and 1% CO2 in a flow-through system can be safely utilized for the storage of pears. Growing location (Oregon vs. Washington) made no difference in the sensitivity to CO2 injury and packing and handling damage.

Enteritidis) colonization in molting hens. Hens were randomly assigned to four treatment groups of 12 hens either full-fed (nonmolt, NM), molted by feed withdrawal (molt, M), a low calcium (LC containing 800 mg calcium), or LC diet supplemented with 110 mg zinc/kg of diet (LC-ZN) in two trials. All hens were challenged orally with 10(5) SE on day 4 of experiment. Hen body weight loss was significantly (P < 0.05) increased and ovarian weight was significantly (P < 0.05) decreased in hens fed the LC or LC-ZN diets compared to NM. Cecal lactic acid concentrations were significantly (P < 0.05) increased in hens fed alternative molting diets. Feed withdrawal molted hens exhibited significantly (P < 0.05) more S. Enteritidis positive and S. Enteritidis crop, cecal, and organ colonization than NM, LC and LC-ZN hens. Alternative molt diets retain sufficient fermentative activity to limit S. Enteritidis colonization and therefore may have potential to avoid the risk of increasing S. Enteritidis colonization associated with feed withdrawal.

The ELISAs had limits of quantification of approximately 1 and 3 ng/mL for BBI and KTI, respectively, and were used to measure active inhibitors in soy infant formulas. Results were compared with enzymatic analyses and demonstrated that most of the trypsin- and chymotrypsin-inhibitory activities of infant formula were due to constituents other than KTI and BBI. The sandwich ELISA for BBI was also effective in detecting soybean germplasm with atypically low levels of BBI. C1 ARS, Western Reg Res Ctr, USDA, Albany, CA 94710 USA.

As the scale of industrial vegetable fermentations increases worldwide, the disposal of salt (chloride) waste, which is generated during processing of these products, has become a major problem. The development of new technology to reduce the amount of salt used in vegetable fermentations may require a greater understanding of the microbial ecology of these fermentations, and may also require the use of starter cultures.

However, fermenting foods are typically very complex ecosystems with active enzyme systems from the ingredient materials interacting with the metabolic activities of the fermentation organisms. Factors such as added salt, particle sizes, temperature, and oxygen levels will also have important effects on the chemistry that occurs during fermentation. This is a brief review of recent research on flavor changes in food fermentations. The emphasis will be on the role of lactic acid bacteria in changing the compounds that help determine the character of fermented foods from plant-based substrates.

But gaining clear insights into the perspectives of ethnic and minority communities is often difficult. This article summarizes an analysis of news articles about resource management issues written by American Indians and published in Indian newspapers and finds ways in which their attitudes differ from those of many other Americans-particularly in the importance of spiritual values and the validity of traditional knowledge. The news stories also indicate a deep lack of trust in land management agencies. This approach-analyzing perspectives on natural resource management as expressed in a community's own words-can be used to learn about the attitudes of other minority populations. Managers who know how all their constituents think about natural resources will better understand the social context in which decisions need to be made.

For effective control of the disease in such areas, the use of custom-made vaccines is required. To circumvent the tedious process of vaccine strain selection, an alternative in the control process is being investigated. Specifically, it is proposed to replace the antigenic determinants of an infectious genome-length cDNA copy of a good SAT vaccine strain with those of appropriate field strains, producing custom-made FMDV chimeras for use in vaccine production. Here the construction of an infectious genome-length cDNA copy of the SAT2 vaccine strain, ZIM/7/83, is described, created utilizing an exchange-cassette strategy with an existing A(12) genome-length cDNA clone. The virus derived from this cDNA (designated vSAT2) displayed excellent growth properties in cell culture, indicating its potential usefulness in the production of custom-made vaccine strains. Evaluation of the growth of various SAT2/A12 chimeras created during the derivation of SAT2 infectious cDNA suggested incompatibilities between the non-structural proteins of ZIM/7/83 and the 5' UTR of A(12).

In this study, we cloned and sequenced a 12.5 kbp BamHI-D restriction endonuclease fragment of the AgMNPV isolate 2D genome that includes the gp64 gene. We compared this highly conserved region with that of other baculoviruses. AgMNPV contained two genes, p22.2 and v-trex, in common with Choristoneura fumiferana MNPV (CfMNPV) that were not present in other baculoviruses. The v-trex gene has homology to a eukaryotic 3' repair exonuclease and appears to have been acquired from an invertebrate host. The v-trex gene product has the potential to be involved in virus recombination or UV-light tolerance. Multigene phylogenetic analysis suggested that AgMNPV is most closely related to Orgyia pseudotsugata MNPV (OpMNPV). AgMNPV differed from other group 1 NPVs in that ChiA and v-cath gene homologues were missing from the region downstream of the gp64 gene. Proteinase assays and genetic probes suggest the v-cath gene is absent from AgMNPV. C1 Univ Brasilia, Dept Cellular Biol, BR-70910900 Brasilia, DF, Brazil.

Various abiotic factors, including sedimentation rates determined from Pb-210 and Cs-137 as a proxy for delivery of riverine organic matter, were also measured to determine which factors influenced these dynamics. Significant decreasing gradients in dissolved oxygen and pH with distance from the river, coupled with trends in sedimentation rates, chloride, and sum nitrate (nitrate + nitrite), revealed that riverine water was mixing with wetland water up to 100 in from the wetland-river interface. Aboveground primary production and total invertebrate densities exhibited Weibull type distributions, with highest rates and numbers occurring 20 to 100 in from the Peshtigo River. Invertebrate densities were largely represented by Asellus sp. isopods (12-53%) and exhibited highest numbers in September. Invertebrate diversity at the genus level linearly decreased with distance from the river based on the Simpson's index of diversity (r(2) = 0.60, p < 0.05) and the Shannon- Wiener function (r(2) = 0.73, p < 0.01). Patterns observed suggest that there is an "optimal" zone for benthic invertebrates in the Peshtigo wetland 20 to 60 m from the Peshtigo River that is protected from high-energy events (e.g., storms, boating) in the Peshtigo wetland by a buffer zone (0 to 20 in) but is close enough to benefit from replenished levels of dissolved oxygen, nutrients, and organic matter delivered via the Peshtigo River.

In addition, demand for high quality and nutritious vegetables has increased. This study was performed to explore the effects of deficit irrigation on yield, fruit quality, lycopene content, vitamin C and sugar composition of red-fleshed diploid and triploid watermelon (Citrullus lanatus (Thunb) Matsum & Nakai) cultivars. Irrigation treatments were 1.0, 0.75 and 0.5 evapotranspiration (ET) rates. Cultivars used were 'Summer Flavor 710', 'RWM 8036', 'Allsweet', 'Sugarlee', and 'SWD 7302' (diploids) and 'Summer Sweet 5244', 'SWT 8706', 'Sugar Time', and 'Tri X Sunrise' (triploids). Total water applied through a subsurface drip system was 395, 298 and 1.73 mm, for the 1.0, 0.75 and 0.50 ET rates, respectively. Total yields were highest at 1.0 ET (53.9 t ha(-1)) compared with 0.5 ET (26.8 t ha(-1)). Triploids had a 34% higher total yield and fewer culls (2%) compared with diploid cultivars (25%). Highest yields were obtained for 'Tri X Sunrise', 'SWT 8706', and 'SWD 7302'. 'Sugar Time' had the highest soluble solids content (13.4%) of all cultivars (range 9.7-11.0%). Triploid cultivars had firmer flesh compared to diploids (12.0 v 9.9. N). Lycopene content increased slightly with maturity (55.8 to 60.2 mug g(-1) fw), and was significantly higher at 0.75 ET and 1.0 ET. Lycopene content averaged over all treatments was 60-66 mug g(-1) fw for triploids and 45 to 80 mug g(-1) fw for diploid fruits. Overall, lycopene and vitamin C content did not decrease with deficit irrigation at 0.75 ET. There was genetic variability for lycopene, vitamin C, and sugar composition, primarily fructose, among diploids and triploids. C1 Texas A&M Univ, Texas Agr Expt Stn, Uvalde, TX 78801 USA.

Using a field cage, an inverse relationship between the amount of Cry1Ac among cultivars versus the weight of bollworm larvae was observed. Larvae that were recovered from the DP 50B cultivar expressing lower Cry1Ac weighed significantly more than larvae collected from the higher expressing NuCOTN 33B cultivar. Cotton plants from NuCOTN 33B were measured as expressing 300% more Cry1Ac than DP 50B plants. The distribution of larval weights indicates that more late-instars (>200 mg) were collected from the lower expressing DP50B cultivar than the higher expressing NuCOTN 33B cultivar. Within a single population, bollworm larvae were highly variable in their development when feeding on Bollgard(R) cotton. Possible reasons and consequences for this variation are discussed.

Material was placed out and mating disruption was commenced at the beginning of April in the first year, and at the beginning of July the second year. This technique effectively prevented males from finding females in female-baited traps placed throughout the plot. Navel orangeworm abundance was high in figs during the first and third flight, but lower in June and July during the second flight. Since Calimyrna figs are not susceptible to attack by navel orangeworm until mid-to-late July, these findings suggest that materials cost can be reduced by beginning treatment later. Implications for insect pest management in figs and other California crops are discussed. C1 ARS, USDA, San Joaquin Valley Agr Sci Ctr, Parlier, CA 93648 USA.

Ten haplotypes were observed. A single haplotype was present among 90% of individuals examined, and a HaeIII haplotype was not present in samples from the Atlantic coast. Significant genetic differentiation existed between Atlantic coast and midwestern United States samples, and between sympatric uni- and bivoltine ecotypes.

Inter-Simple Sequence Repeat-Polymerase Chain Reactions (ISSR-PCR) were performed with a 5'-anchored ISSR primer. Twenty-five markers were generated with four populations ( 40 individuals) of G. morrilli. Twenty-three were polymorphic and the percentage of polymorphic loci was 92%. Most markers could be considered diagnostic since there was no band sharing between the Texas and California populations. Such differences typically are not found unless the populations are reproductively isolated. Exact tests for population differentiation indicated significant differences in marker frequencies among the populations. Comparison of other genetic differentiation estimates, which evaluate the degree of genetic subdivision, demonstrated excellent agreement between G(ST) and theta values, 0.92 and 0.94, respectively, indicating that about 92 to 94% of the variance was distributed among populations. The average genetic divergence ( D), as measured by genetic distance, was extremely high (Nei = 0.82 and Reynolds = 2.79). A dendrogram based on Nei's genetic distance separated the Texas and California populations into two clusters, respectively. Amplification of the Internal Transcribed Spacer-1 (ITS-1) region showed no size differences, whereas the ITS-2 DNA fragment varied in size between the two geographic populations. The ITS-2 fragment sizes were about 865 and 1099 base pairs for the California and Texas populations, respectively. The present study using the two molecular methods provides novel data critical to the glassy-winged sharpshooter/Pierce's disease biological control program in California.

The use of RNAi technology for gene silencing in Lepidoptera has lacked significant attention compared to other systems. To demonstrate that RNAi can be utilized in the lepidopteran, Plodia interpunctella, we cloned a cDNA for tryptophan oxygenase, and showed that silencing of tryptophan oxygenase through RNAi during embryonic development resulted in loss of eye-color pigmentation.

A laboratory investigation was conducted to quantify the foraging behavior of the adults of five common whitefly predators presented with a surfeit of whitefly eggs, nymphs, and adults. The beetles, Hippodamia convergens Guerin-Meneville and Collops vittatus ( Say) fed mostly on whitefly eggs, but readily and rapidly preyed on all of the whitefly lifestages. The true bugs, Geocoris punctipes ( Say) and Orius tristicolor ( Say) preyed almost exclusively on adult whiteflies, while Lygus hesperus Knight preyed almost exclusively on nymphs. The true bugs had much longer prey handling times than the beetles and spent much more of their time feeding (35- 42%) than the beetles (6- 7%). These results indicate that generalist predators vary significantly in their interaction with this host, and that foraging behavior should be considered during development of a predator-based biological control program for B. tabaci.

Primary cultures were initiated in September 2002 from 2 to 4 day old eggs in either modified TC-100 or ExCell 400 medium. From these initial cultures, one, originally isolated in the Ex-Cell medium, produced sufficient cell growth to allow subcultivation and eventually led to the establishment of two cell strains, one that forms multicellular vesicles in suspension and one consisting of tightly attached epithelial-like cells. The strains were compared to an extract from E. kuehniella eggs by isozyme analysis and shown to be from the same species. Both strains were inoculated with various insect viruses, including nucleopolyhedroviruses from Autographa californica, Anagrapha falcifera, Anticarsa gemmatalis, Galleria mellonella, Heliothis armigera, Helicoverpa zea, Lymantria dispar, Plutella xylostella, and Rachoplusia ou. Both strains were highly susceptible to most of the nucleopolyhedroviruses ( with the exception of the viruses from Helicoverpa zea and Lymantria dispar which did not show cytopathology to either cell strain) with large numbers of occlusion bodies produced in most of the inoculated cells. Our results suggest these new lines can be useful in biocontrol research. C1 USDA ARS, Insect Biocontrol Lab, BARC W, Beltsville, MD 20705 USA.

AcRFP recombinants produced incomplete polyhedra with low infectivity for Trichoplusia ni larvae, whereas AcuW21-23GFP produced normal polyhedra with high infectivity. Electron microscopy of AcRFP CL14 showed the incorporation of very few viral particles into polyhedrin matrix protein material. The LC50 for AcuW21-23GFP was 0.10 occlusion bodies/mm(2), whereas the LC50 values for several AcRFP recombinants ranged from 20 to 329 occlusion bodies/mm(2). When both the RFP and GFP recombinants were exposed to ultraviolet light (UV-B 280-320 nm), the results support the conclusion that these fluorescent proteins afford some protection against its damaging effects.

We evaluated virulence, host specificity, biomass production, conidiation, conidial germination, and a genetic fingerprint of 3 strains of Paecilomyces fumosoroseus after passage in vitro or in vivo in Diuraphis noxia or Plutella xylostella. Strain 4461 did not change in virulence toward D. noxia or P. xylostella after 30 passages in vitro nor after 15 passages in D. noxia. However, it lost virulence toward D. noxia after 15 passages in P. xylostella and did not regain virulence after 5 passages in D. noxia. Passage in D. noxia did result in a loss in conidiation for strain 4461, and passage in vitro resulted in a reduction in the speed of germination. Strain 4481 was the least variable and did not change in any of our tests. Strain 4491 did not change in virulence after passage in vitro nor after passage in D. noxia. It lost virulence toward D. noxia after passage in P. xylostella but regained virulence after re-passage in D. noxia. Mycelial dry weight and conidiation were both reduced after passage in vitro, but were increased after passage in D. noxia. These two traits did not change after passage in P. xylostella. Germination speed was reduced after in vitro passage of strain 4491. No change in banding pattern was observed for any strain using 14 primers for RAPD-PCR. These results demonstrate the intraspecific variability and phenotypic plasticity of strains of P. fumosoroseus. Stability of virulence after in vitro passage is clearly a desirable trait for a mass-produced biocontrol agent. However, a change in host specificity or productivity in vitro, as we observed for some strains, must be monitored and minimized. Published by Elsevier Inc.

The controller design method uses discrete-time state-feedback control with a quadratic penalty function, physically based states, and no state estimation. A simple, linear model of canal pool response, the integrator-delay model, is used to define the state transitions. All controllers within this class are tuned for the entire canal using optimization techniques. This avoids the tedious task of manually tuning simple controllers. The relative performance of the various controllers within this class can be directly compared without simulation, since the same objective function is used to tune each controller. An example is provided which suggests that the fully centralized controller will perform better than a series of local controllers. However, reasonably good performance can be obtained for some intermediate PI controllers that pass information to one additional check structure upstream and downstream. This should limit some of the difficulties reported for full optimal controllers where all check structures respond to water-level. errors in all pools (e.g., saturation of inputs). The results of simulation studies of these controllers are provided in a companion paper. C1 US Water Conservat Lab, USDA ARS, Phoenix, AZ 85040 USA. Corus RD&T, NL-1970 CA Ijuiden, Netherlands.

These controllers range from a series of simple proportional-integral (PI) controllers to a single centralized controller that considers lag times. In this paper, several controllers within this class were tuned with the same quadratic performance criteria (i.e., identical penalty functions for optimization). The resulting controllers were then tested through unsteady-flow simulation with the ASCE canal automation test cases for canal 1. Differences between canal and gate properties, as simulated and as assumed for tuning, reduced controller performance in terms of both water-level errors and gate movements. The test case restrictions placed on minimum gate movement caused water levels to oscillate around their set points. This resulted in steady-state errors and much more gate movement (hunting). More centralized controllers handle unscheduled flow changes better than a series of local PI controllers. Controllers that explicitly account for pool wave travel times did not improve control as much as expected. Sending control actions within a given pool to upstream pools improved performance, but caused oscillations in some cases, unless control signals were also sent downstream. A good compromise between controller performance and complexity is provided by controllers that pass feedback from a given water level to the check structure at the upstream end of its pool (i.e., that used for downstream control of an individual pool) and to all upstream and one downstream check structures.

To elucidate the mechanism mediating the increase in apoA-I gene expression by these compounds, plasmid constructs containing serial deletions of the apoA-I promoter region were generated. The smallest region maintaining response to E2 and genistein spanned the -220 to -148 sequence, and the estrogen antagonist 10182,780 completely inhibited the E2 and genistein effect. Nuclear extracts from cells treated with E2 and genistein showed increased binding to site B oligonucleotide (-169 to -146), and nuclear extracts from genistein-treated cells showed increased binding to an early growth response factor I (Egr-1) oligonucleotide compared to control cells. An increase in the concentrations of Egr-1 and hepatocyte nuclear factor-3beta was observed in nuclear extracts of cells treated with both compounds compared to control cells. Treatment with a specific inhibitor of mitogen-activated protein (MAP) kinase, but not with other inhibitors, abolished the stimulation of apoA-I gene expression by E2 and genistein. EM These results indicate that the MAP kinase pathway is involved in the regulation of apoA-I gene expression by genistein and E2, possibly through downstream regulation of transcription factors binding to the promoter region.

Evaporative light-scattering detection (ELSD), in parallel with atmospheric pressure chemical ionization mass spectrometry (APCIMS), yielded excellent quantitative and spectral data. Non-linear detector responses of the ELSD were overcome by performing a simple exponential transformation of the detector response data. The transformation allowed for single-point calibrations that yielded quantitative results with excellent accuracy and precision. Method recovery and precision were determined from maltose-fortified conifer tissues. Maltose recovery was 101.7% [relative standard deviation (RSD) = 9.74%] for homogenized Douglas-fir (Pseudotsuga menziesii) needle tissue fortified at 1.01 mg/g and 107.8% (RSD = 2.47%) for tissue fortified at 10.1 mg/g. Maltose recovery from fortified western redcedar (Thuja plicata) tissues (7.60 mg/g) was 93.0% (RSD = 3.0%). The method limit of detection (MLOD) was 0.24 mg/g for maltose in Douglas-fir. The method was employed for the quantitative analysis of soluble carbohydrates in Douglas-fir needles, collected from new and previous-year's growth for 7 weeks after the emergence of new growth (bud break). Needles collected from dormant trees were also analyzed. The concentrations of fructose and glucose were consistently greater in previous-year's growth vs. new and dormant growth.

We found that different forest types could be distinguished and mapped using remotely sensed data. To determine the temporal and spatial distribution of flies, we collected flies coming to rotted liver at 82 sites in ten vegetation types (open areas, edge forest, dry scrub forest, forest successional stage 1, forest successional stage 2, forest successional stage 3, forest successional stage 4, forest successional stage 5, mature forests, palm swamp forest, and forest along streams) over three seasons (dry, transitional, wet). Nine of the vegetation types (excluding dry scrub forest) were identified and mapped using SPOT XS and Landsat 5 TM satellite data. Screwworm flies were most abundant during the transition from wet to dry season. Fly numbers were consistently higher in forest habitats, particularly those with trees 20-30 m in height and a fairly open canopy composed of many deciduous species that shed their leaves during the dry season. Screwworm numbers were also high in palm swamp forest, edge forest, and mature growth forest. Traps sampled in open areas bad fewer flies and were unrelated to proximity to cattle. Females accounted for 88% of the total fly counts. This study further substantiates the importance of forests in the ecology and behavior of screwworm flies and demonstrates that remotely sensed data can be used to construct the spatial distribution of these flies in a tropical landscape. We discuss implications of this information to the screwworm eradication program. C1 USDA ARS, Screwworm Res Lab, Panama City, Panama.

Similar measurements are shown for tree-ripened peaches, which were obtained to assess possibilities for a permittivity-based maturity index. Broadband (10 MHz to 1.8 GHz) permittivity measurements are shown for several fruits and vegetables as a function of temperature from 5 to 95 degrees C.

Techniques for moisture measurement, including electronic moisture meters, are also discussed briefly, and the need for better moisture sensing techniques for modern agricultural on-line moisture monitoring is described. Principles of microwave free-space measurements involving attenuation and phase-shift determination are explained, and density-independent functions of the grain permittivity are presented that permit reliable moisture sensing applicable to moving grain in which bulk density variation occurs. Three different approaches are discussed for determining moisture content and bulk density of grain from microwave measurement of the dielectric properties. A new moisture calibration function, based on complex-plane plots of dielectric constant and loss factor, each divided by bulk density, is described, which promises a universal calibration for different types of grain and seed. This important advantage should encourage commercial development for practical use. C1 [Nelson, Stuart O.; Trabelsi, Samir] ARS, USDA, Richard B Russell Agr Res Ctr, Athens, GA 30605 USA.

This study was undertaken to examine the importance of pre-treatments. Diffuse reflectance NIR (1100-2500 nm) spectra of ground wheat and forages were separately analysed. For ground wheat, the effect of spectral pre-treatment on the PLS equations for protein content and sodium dodecyl sulphate (SDS) sedimentation volume (a protein quality index) was examined. For forages, similar examinations were performed on crude protein content and lignin content. Results indicate that while pre-treatment is indeed important, statistical significance, as determined by the F-test of correlated variances, is often not established. Protein content calibrations tend to be enhanced by scatter correction, as opposed to smoothing or derivatisation, whereas the SDS sedimentation volume and lignin content calibrations favoured these convolution functions. It is recommended that the selection of the best pretreatment for an analyte be based on the combination of statistical testing and the modeller's judgement.

Seventy-five mixtures of cellulose, starch, pectin, locust gum, glucose and xylitol were scanned in the near- and mid-infrared in three physical states (wet, simple mixtures of dry constituents and mixtures dried together). These final samples (mixtures dried together) were prepared by drying wet mixtures/solutions while under constant stirring to prevent separation of the insoluble polymers by settling, which occurs during normal oven drying. Final drying of the resulting solid mass was carried out in a vacuum oven at 60degreesC. The dried mass was then ground and scanned in the spectrometer. All dry samples were ground to a flour-like consistency using a A-10 Tekmar Analytical Mill to avoid effects due to gross differences in particle size. The wet samples were produced by adding sufficient water to result in samples of a putty like consistency. Spectra were taken on a Digilab FTS-65 Fourier transform spectrometer equipped with near- and mid-infrared benches by diffuse reflectance. Results demonstrated that the effects of water and physical state (matrix effects), seen previously with simple model systems, can be extrapolated to draw some general conclusions about real world calibrations, but that developing model systems to either predict the feasibility of developing a calibration or to determine the reason for the specific results of a calibration must be done with extreme care. For example, using simple mixtures of components to determine whether a calibration for the same components in a different physical condition (melted together, dried together etc.) might well lead to erroneous conclusions about its usefulness. Also, from the results, it would appear that factors (e.g. physical state) other than the mere presence of large amounts on water in samples can account for the decrease in calibration accuracy often seen in samples with high moisture contents as compared to their dried counterparts. Finally, the results seen using mid-infrared spectra indicate that mid-infrared diffuse reflectance spectroscopy might be feasible even with samples containing high percentages of water.

In this study, we developed a calibration for determining shive content in flax using near infrared (NIR) spectroscopy and applied the model to pilot plant processed flax to predict shive content. The model based on "ground" mixtures performed best from multiplicative scatter correction after a second derivative treatment of the spectral data, giving a standard error of cross-validation of 0.35% using five factors. Prediction samples were Jordan enzyme(ER) and Natasja dew-retted (DR) flax that was collected after various stages of processing. When the model was applied to the "ground" flax, a high correlation was obtained between the NIR predicted value and actual shive content, giving a correlation coefficient of >0.98 for both retted flax samples. However, when the model was applied to the "as-is" flax, a slope and bias were observed. These deviations were corrected by a linear regression between predicted values of "ground" and "as-is" flax. For the NIR analysis of ER flax, the shive content decreased rapidly by the third processing step to 4 to 5% and almost 0% after the last step. For the DR flax, the shive content continuously decreased with processing to about 5% after the last step. The results indicate that it is possibile to measure shive in flax on a commercial processing line. C1 ARS, USDA, Richard B Russell Agr Res Ctr, Athens, GA 30605 USA.

In the USDA Flax Fiber Pilot Plant, flax is first cleaned through four separate modules and then passed through a Shirley Analyzer to further clean fibres for high-value applications such as textiles. Often, multiple passages through the Shirley Analyzer are employed to obtain higher quality fibres, but it is difficult to determine when the limit for cleanliness is reached by this method. Further, it is clear that materials other than the woody shive components are being removed by Shirley-cleaning, and a method is needed to assess cleanliness beyond the measure for shives. In this study, we attempted to establish an index to determine the degree of purity of flax fibre during the secondary cleaning stage for high quality fibre. Dew-retted (DR) flax and enzyme-retted (ER) flax, which had been first processed through the USDA Flax Fiber Pilot Plant and assessed for shive content, were processed with 10 repetitions of cleaning through the Shirley Analyzer. For both flax samples, absorbances at 1730, 1766, 2312 and 2350 nm decreased with successive Shirley-cleaning steps. These wavelengths appeared to originate from the epidermal layer (EL) that was associated with the flax fibre, an index was calculated using 11 training samples and validated using 10 independent test samples from the same flax samples. Index values gradually decreased with successive Shirley-cleaning steps for both retted flax samples; a lower index value indicated cleaner fibre. Different curves were apparent for the two flax samples, suggesting variations in the cleanliness of the starting material or perhaps differencess in fibre composition. The results suggest it is possible to determine the extent of cleaning of flax fibre using NIR spectroscopy beyond that for shive content based on the epidermal layer of the plant.

Wood property calibrations may be improved by using non-linear calibration methods. In this study, we compare calibrations developed using partial least squares (PLS) regression and least-squares support vector machine (LS-SVM) regression, a relatively new technique for modelling multivariate, non-linear systems. LS-SVM regression provided the strongest calibration statistics for all wood properties. For an equivalent number of latent variables, the predictive performance of the MFA LS-SVM calibrations were superior to those of the corresponding PLS calibration, while predictive results for air-dry density and E-L(SS) were similar for both calibration methods.

Activation of insulin signaling components leading to translation initiation is associated with the feeding-induced stimulation of muscle protein synthesis in neonates. In this study, we examined the individual roles of insulin and amino acids in the activation of insulin signaling components leading to translation initiation, specifically, the insulin receptor (IR), insulin receptor substrate 1 (IRS-1), phosphatidylinositol 3-kinase (PI 3-kinase), protein kinase B (PKB) and ribosomal protein S6. Insulin secretion was blocked by somatostatin in food-deprived, 7-d-old pigs (n = 8-12/group); insulin was infused to achieve plasma levels of similar to0, 17, 52, and 255 pmol/L (similar to0, 2, 6, 30 muU/mL), and amino acids were clamped at food-deprived or fed levels. In skeletal muscle, insulin increased the activation of IR, IRS-1, PI 3-kinase, PKB and S6 and stimulated protein synthesis. In liver, insulin increased the activation of IR, IRS-1, PI 3-kinase, PKB and S6, but had no effect on protein synthesis. Raising amino acids from the food-deprived to the fed level did not alter the insulin-induced activation of IR, IRS-1, PI 3-kinase and PKB but increased S6 phosphorylation and protein synthesis in skeletal muscle and liver. The results suggest that the stimulation of protein synthesis in muscle by insulin involves activation of insulin signaling components, and the stimulation of protein synthesis in muscle and liver by amino acids occurs by mechanisms independent of the early steps of this pathway. Furthermore, amino acids do not alter the insulin-stimulated activation of early steps in the insulin signaling pathway.

Because choline and folate are interrelated metabolically, we investigated the effects of maternal dietary folate availability on progenitor cells in fetal mouse telencephalon. Timed-pregnant mice were fed a folate-supplemented (FS), control (FCT) or folate-deficient (FD) AIN-76 diet from d 11-17 of pregnancy. FD decreased the number of progenitor cells undergoing cell replication in the ventricular zones of the developing mouse brain septum (46.6% of FCT), caudate putamen (43.5%), and neocortex (54.4%) as assessed using phosphorylated histone H3 (a specific marker of mitotic phase) and confirmed by bromodeoxyuridine (BrdU) labeling of the S phase. In addition, 106.2% more apoptotic cells were found in FD than in FCT fetal septum. We observed 46.8% more calretinin-positive cells in the medial septal-diagonal band region of FD compared with pups from control jams. FS mice did not differ significantly from FCT mice in any of these measures. These results suggest that progenitor cells in fetal forebrain are sensitive, to maternal dietary folate during late gestation.

Nevertheless, two large scale intervention studies in humans using high doses of beta-carotene found that beta-carotene supplementation resulted in more lung cancer rather than less lung cancer among smoking and asbestos exposed populations. Studies conducted in the ferret have elucidated molecular mechanisms behind this observation, in that high-dose beta-carotene and smoke exposure in these animals leads to squamous metaplasia, a pre-cancerous lesion in the lung. High dose beta-carotene in the smoke exposed animals was found to give rise to a number of transient oxidative metabolites, which include P450 enzymes that result in the destruction of retinoic acid, and diminished retinoid signaling, and enhanced cell proliferation. In addition, eccentric cleavage beta-carotene metabolites facilitate the binding of smoke derived carcinogens to DNA. In other ferret studies low dose beta-carotene smoke exposure provided mild protection against squamous metaplasia. Thus, it appears that the explanation of the apparent paradoxical effects of beta-carotene on lung cancer is related to dose. The metabolism and breakdown of natural products should be thoroughly investigated in animal models before embarking on large scale intervention trials, particularly when using unusually high doses that greatly exceed normal dietary levels.

Thus, a greenhouse test with 11 plant species with a wide range of susceptibility to Ni toxicity was conducted to determine if Ni phytotoxicity of all species could be ameliorated by a high rate of limestone. At the original pH of 5.2, the Welland soil (Typic Epiaquoll; 2900 mg kg(-1) Ni) was severely phytotoxic to all plant species tested. Toxicity symptoms in dicots included interveinal chlorosis and necrosis of leaves. In grasses, a banded chlorosis was present. Two limestone rates, 2.5 and 50 Mg ha(-1), were included in and plant species significantly affected soil pH, the test. Both liming and 0.01 M Sr(NO3)(2)-extractable soil Ni. Increase in pH exponentially decreased Sr(NO3)(2)-extractable soil Ni. Grass species were more resistant to Ni toxicity than dicots. Liming soil to pH of 5.9-6.3 enabled good growth of several grass species, but dicot species were still stunted or died. Making the soil calcareous (pH 7.7-7.8) ameliorated Ni toxicity of this highly contaminated soil for all species tested. Concentration of Ni in shoots associated with 25% yield reduction varied among species ranging from 9 to 122 mg kg(-1) dry shoots.

Interactions between salinity and NH4+/NO3- ratios with tomato genotypes were studied. The effect of four ammonium levels (0, 1, 2, 4 mM of total 8 mM N) and two salinity levels (0 and 45 mM NaCl) on cv. "R-144", and the effect of two salinity levels (0 and 45 mM NaCl) on four tomato hybrids ("R-144", "R-175", "FA612", and "FA624") were studied in two greenhouse experiments. The effects of two NH4+ levels, (0 and 2 mM out of total N at 8 mM), and two salinity levels (0 and 20 mM NaCl) on large-fruit ("R-144") and small-fruit ("FA612") tomato hybrids were also studied in a net-house. The NaCl at 45 mM resulted in a smaller leaf area index (LAI), lower plant dry matter and lower fruit yield than controls. Addition of 1 mM NH4+ to the nutrient solution contributed to improved growth. Genotypes bearing large fruits were more prone to suffer yield losses under saline conditions than those with small fruits. In the second experiment, salinity treatment resulted in improved fruit TSS, EC and titratable acidity in all of the hybrids except of "FA612". Fruit TSS was inversely correlated with yield. However, the ratio in TSS decline versus yield varied among the hybrids. At mild salinity (20 mM NaCl), fruit TSS and titratable acidity were significantly increased in "R-144" while yield was slightly decreased. Transpiration rate decreased with the presence of ammonium in the nutrient solution in both hybrids. The highest and lowest values were obtained for "FA612" and "R-144", respectively. The detrimental effect of salinity is mainly attributed to the decrease in LAI and the subsequent reduction in water uptake, resulting in low fruit weight. Addition of 1 mM ammonium to 7 mM nitrate in the nutrient solution had an ameliorating effect on tomato fruit yield under salinity.

A field study was conducted to evaluate the use of multispectral imagery for estimating corn (Zea mays L.) grain yield, in-season biomass and nitrogen (N) concentration under varying N and drought stresses. The experiment was a split-plot design with three replications using a factorial arrangement of treatments. Three irrigation (whole-plot) treatments included dry land, irrigation based on 0.5, and full evapotranspiration (ET). Sub-plot treatments included five N rates (0, 45, 90, 134, 269 kg N ha(-1)). Multi-spectral imagery consisted of four wavebands; blue (485 nm +/- 35 nm), green (550 nm +/- 35 nm), red (660 nm +/- 30 nm), and near-infrared (NIR) (830 nm +/- 70 nm). Imagery was collected on various dates throughout the growing season; biomass sampling was performed within two days of image collection. Grain yield, in-season biomass, and N concentration increased with increasing N rate regardless of sampling date or year. Yield was only affected by irrigation during 1997 due to a significant difference in rainfall between 1997 and 1998, 247 vs. 457 mm, respectively. Regression correlation coefficients for the 1998 values were generally higher compared to 1997 values across years for imagery collected at similar growth stages, possibly due to differences in sensor sensitivity or the increased plant response to applied N. Regression correlation coefficients increased as the growing season progressed. The green waveband and normalized difference greenness vegetation index (GNDVI) had the greatest ability to estimate grain yield in the presence of varying N and/or drought stresses. This study demonstrates the ability of multispectral imagery analysis to estimate grain production in the presence of N and/or drought stresses. C1 Univ Nebraska, Dept Agron, Lincoln, NE USA.

At low amounts of plant available N the relative proportion of N in the roots will be high. As under conditions of high N availability, the proportion of N in vegetative and reproductive tillers as well as the number of vegetative and reproductive tillers will increase. However, the correlation between plant N content and tiller production is not known. Therefore, a growth chamber experiment was performed to investigate this relationship in perennial ryegrass. The relation is important to better predict the effect of N application on tiller production. Plants were grown in nutrient solutions containing diminishing amounts of N over 36 days. At the end of the growth period, N and carbon (C) concentrations of the plant tissues, as well as the tiller production, were analyzed. Higher N concentrations were found in leaves than in roots. Depending on the N concentration in leaves, two groups of plants could be identified. One group (I) had an average leaf N concentration of 1-2%, which was distinct from the other group (II) with an average leaf N concentration of above 2%. At the end of the experimental period, the accumulated N content was equally distributed between roots, stems, and leaves in group I, whereas N was preferably stored in the leaves and stems in group II. The lowest production of tillers was achieved with 0.01 g N plant(-1), and the greatest number of tillers was reached with 0.19 g N plant(-1). The greatest number of tillers produced per plant in group II was reached before the end of the experimental period, indicating that maximum tiller production was reached under the given conditions. In group I, a linear model described the correlation between the number of tillers produced per plant and N content per plant. In group II, a model with an exponential rise to maximum described the relationship between these parameters. The results indicate, that the production of tillers in perennial ryegrass is closely related with N content in the plant. The results are further discussed in relation to N dynamics during vegetative and reproductive growth in perennial ryegrass.

Today, sage-grouse populations are declining throughout most of their range. Population dynamics of sage-grouse are marked by strong cyclic behavior. Adult survival is high, but is offset by low juvenile survival, resulting in low productivity. Habitat for sage-grouse varies strongly by life-history stage. Critical habitat components include adequate canopy cover of tall grasses (greater than or equal to 18 cm) and medium height shrubs (40-80 cm) for nesting, abundant forbs and insects for brood rearing, and availability of herbaceous riparian species for late-growing season foraging. Fire ecology of sage-grouse habitat changed dramatically with European settlement. In high elevation sagebrush habitat, fire return intervals have increased (from 12-24 to > 50 years) resulting in invasion of conifers and a consequent loss of understory herbaceous and shrub canopy cover. In lower elevation sagebrush habitat, fire return intervals have decreased dramatically (from 50-100 to < 10 years) due to invasion by annual grasses, causing loss of perennial bunchgrasses and shrubs. Livestock grazing can have negative or positive impacts on sage-grouse habitat depending on the timing and intensity of grazing, and which habitat element is being considered. Early season light to moderate grazing can promote forb abundance/availability in both upland and riparian habitats. Heavier levels of utilization decrease herbaceous cover, and may promote invasion by undesirable species. At rates intended to produce high sagebrush kill, herbicide-based control of big sagebrush may result in decreased habitat quality for sage-grouse. Light applications of tebuthiuron (N-[5-(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl]-N,N'-dimethylurea) can decrease canopy cover of sagebrush and increase grass and forb production which may be locally important to nesting and foraging activities. The ability of resource managers to address sage-grouse habitat concerns at large scales is aided greatly by geomatics technology and advances in landscape ecology. These tools allow unprecedented linkage of habitat and population dynamics data over space and time and can be used to retroactively assess such relationships using archived imagery. The present sage-grouse decline is a complex issue that is likely associated with multiple causative factors. Solving management issues associated with the decline will require unprecedented cooperation among wildlife biology, range science, and other professional disciplines.

Most grasshoppers species are innocuous, but control with insecticides is non-discriminatory among species. The objectives were to evaluate the effects of prescribed burning on the abundance and biomass of grasshoppers and to determine if species could be selectively controlled with prescribed fire. Twenty-four, 4-ha sites were selected in a sand sagebrush-mixed prairie near Woodward, Okla. and blocked by pasture. Plots were randomly assigned fall-, spring-, or non-burned treatments within block with 4 replications per treatment for each of 2 years. Grasshopper biomass and abundance were sampled in late July and early August by sweeping with canvas beating nets. Specimens were weighed to the nearest 0.1 mg and identified to species. Fire treatments had no effects on the total abundance or biomass of grasshoppers across species, with about 10 grasshoppers weighing 4,090 mg per 150 sweeps. Fire effects on the 4 most common species were variable and could be explained by the biology of the insects. Melanoplus bowditchi and M. flavidus were unaffected by fire treatment. Hesperotettix viridis is sensitive to damage to its host plants and was reduced about 88% by fire in either season. Ageneotettix deorum abundance was 65% lower on fall-burned plots. We hypothesize the reduction occurred because the species' eggs are laid near the soil surface and exposed to the heat of passing fire. Fire prescriptions may be developed to target species-specific vulnerabilities and reduce pest grasshoppers while maintaining the food base for grasshopper predators.

We tested the hypotheses that prescribed burning of aerated (top-growth removal of woody plants) plots during late summer would decrease protein-precipitating tannins in browse, increase forb biomass, and increase deer utilization compared to a second aeration. Ten patches of brush, ranging in size from 2.8-8.1 ha, were aerated during spring 1999. In late summer 2000, maintenance treatments were applied; 5 patches were burned and 5 were aerated a second time. Standing crop, nutritional quality, and tannin concentrations (browse only) of deer forages were estimated. Deer tracks crossing bulldozed lanes surrounding each patch were counted to estimate deer use. Standing crop of browse, forbs, grass, succulents, protein-precipitating tannins in browse, and track density did not differ between treatments. Based on deer use and forage biomass response, burning and a second aeration 16-17 months following an initial aeration appear to have similar effects on habitat characteristics and use of cleared patches by white-tailed deer. Because of lower cost, we recommended prescribed burning as a maintenance treatment of aerated shrublands. C1 USDA, Nat Resources Conservat Serv, Pearsall, TX 78061 USA.

In July 1999, Airborne Visible Infrared Imaging Spectrometer (AVIRIS) data were acquired in northeastern Wyoming, near Devils Tower National Monument. Using the reflectance spectrum of flowering leafy spurge, leafy spurge occurrence was determined using a new method of spectral mixture analysis, Mixture Tuned Matched Filtering (MTMF). Ground reference data (146 sites) were obtained 2 weeks before and after AVIRIS overflight to test the classification accuracy of leafy spurge. For 3 land cover types: mixed prairie, riparian, and coniferous woodlands, the presence or absence leafy spurge was detected with an overall accuracy of 95% using a 0.10 threshold for detection. Differences in classification thresholds resulted in a trade-off between false positives, pixels that were mapped as leafy spurge but did not contain leafy spurge on the ground, and false negatives, areas that had leafy spurge on the ground but were not mapped as leafy spurge. Detection of leafy spurge occurrence was best for mixed prairie and riparian cover types, and somewhat less successful for conifer woodlands because of interference from tree crowns and their shadows. The advantage of the MTMF technique is it allows automated processing of hyperspectral imagery to generate accurate maps of leafy spurge occurrence. C1 Univ Wyoming, Dept Bot, Laramie, WY 82071 USA.

Innovative and rapid methods continue to be devised to detect, isolate and measure the potential for foodborne disease caused by foodborne Salmonella spp. in the U.S.A. To develop rapid in vitro assays for assessment of virulence, it is important to understand the physiological and genetic principles that enable Salmonella to become invasive and infective within a host. Combining this knowledge with rapid detection technologies will lead to more extensive and real time appraisal of Salmonella physiological and pathogenic status in food matrices.

Twenty-five gram of ground beef patties were inoculated with 1 CFU/g of O157 or non-O157 (STEC) stored at 7C for 5 h and incubated with 100 mL added EC broth at 37C and 140 r.p.m. shaking for 20 h. Ten mug/mL of ofloxacin was added to the EC broth after 20 h of incubation to enhance toxin production. After 4 more hours of incubation, samples were removed and centrifuged for 10 min at 5000 r.p.m. The supernatant was removed and saved and a bacterial protein extraction reagent was used to lyse the cells in the pellet and release intracellular SLTs (Fraction I) which were then recombined with extracellular SLTs (Fraction II) present in the supernatant. Immunomagnetic beads coated with monoclonal antibodies specific to Shiga-like toxins I and II were applied to capture and concentrate the toxins and captured toxins were labeled with lanthanide-tagged antitoxin antibodies to from sandwiched complexes prior to detection by a TRF reader TRF pathogen detection levels, defined as signals greater than or equal to2 x uninoculated samples, were achieved in all STEC inoculated samples and no cross-reactivity was observed with either nonpathogenic microflora present on the meat or nontoxin-producing E. coli K12 inoculated samples.

To examine the relationship between inflammatory cytokine production and body cell mass (BCM) in women with stable, medically well-controlled rheumatoid arthritis (RA). Methods. Case-control study of 20 women with RA and 20 healthy women matched for age, race, and body mass index (kg/m(2)). Tumor necrosis factor-alpha (TNF-alpha), interleukin 1beta (IL-1beta), and IL-6 production were measured by specific, non-cross-reacting ELISA of peripheral blood mononuclear cells (PBMC) cultured with and without 100 ng/ml of endotoxin. Total BCM was assessed by the reference method of whole-body counting of naturally occurring radioactive potassium-40. Results. Patients with RA were cachectic, with 14% less BCM (p < 0.001) and higher TNF-alpha production (p < 0.05) than controls. TNF-alpha production was inversely associated with BCM both without (r = -0.51, p = 0.03) and with (r = -0.57, p = 0.01) endotoxin stimulation in patients but not in controls. In multivariate linear regression models, these inverse associations remained significant after adjustment for age and physical activity. No association was found for IL-1beta or IL-6 production in these models. Conclusion. Women with stable, medically well-controlled RA have lower than normal BCM that is inversely associated with elevated TNF-alpha production.

Generally, this requires land be taken out of cultivated agriculture; however, it has been postulated that gains in soil C can be quickly eliminated with return to cultivation. The objective of this study was to examine the impact of converting land back into cultivated agricultural management on C sequestration within two different soil types. Soil samples from nine depth increments (0-5, 5-10, 10-15, 15-30, 30-45, 45-60, 60-75, 75-90, 90-105 cm) (0-2, 2-4, 4-6, 6-12, 12-18, 18-24, 24-30, 30-36, 36-42 in) were collected from a Blanton loamy sand (loamy, siliceous, semiactive, thermic Grossarenic Paleudults) and an Urbo clay loam (fine, mixed, active, acid, thermic Vertic Epiaquepts) in central Alabama, USA, that were under different land management systems. Management systems included forest, permanent pasture, and pasture converted to continuous cultivation for 1 and 2 years. Within the loamy sand soil, land management also included continuously cultivated (>40 yr), weedy-fallow for 5 years, and returned to cultivation after weedy-fallowed for 4 years. Soil samples were analyzed for total nitrogen (N), organic C, and soil C:N ratio. The clay loam soil had higher capacity to sequester C [147 Mg ha(-1) (66 tons ac(-1)) for pasture], than the loamy sand soil [(74) Mg ha(-1) (33 tons ac(-1)) for pasture]. Little difference was observed between the forested soil and the permanent pasture in the clay loam soil, with 139 Mg ha(-1) (62 tons ac(-1)) and 147 Mg ha(-1) (66 tons ac(-1)), respectively. In the loamy sand soil, large differences were observed for C between the forested and the permanent pasture sites, with 127 Mg ha(-1) (57 tons ac(-1)) and 74 Mg ha(-1) (33 tons ac(-1)), respectively. Results indicate that the vulnerability of soil to lose sequestered C will likely depend on soil type. The clay loam soils, although having higher levels of C, lost 55% Of its C with 2 years of cultivation, while the loamy sand soil showed little significant loss of C content [below 0-5 cm (0-2 in)] within the same time frame.

Identification of areas likely to be affected by impending P-based regulations wilt allow regulators and conservation officials to better target technical and financial assistance. A statewide GIS analysis based on an extensive soil testing database and available geospatial data (including land cover, streams, and livestock density) found that various regions of Pennsylvania would be affected by the P-index restrictions for different reasons. In the southeast and parts of the northeast, high soil test P levels associated with intensive animal agriculture required a full assessment of P source and transport factors under the P-Index. In north- and south-central and southwest Pennsylvania, the P-index assessment was required because of the proximity of much of the region's farmland to surface waters. Additionally, nearly half of agronomic soil samples exceeded the optimum P level for crops, suggesting widespread over fertilization and an ongoing build up of soil P stocks. Soil P was found to increase with increasing animal density and the highest animal density areas had a large number of nutrient impaired streams. When samples were separated based on cover type, croplands exhibited the highest P levels, followed by grasslands and then pastures. Finally, a weighted combination of the percentage of soil samples exceeding 200 ppm P and the proportion of agricultural lands within 150 ft (45.7 m) of streams indicated that southeastern Pennsylvania, especially Lancaster County, would be most affected. How farm operators adapt to P-based nutrient management, via on- and off-farm strategies, will determine the severity of the impact and the necessity of government assistance.

Useful hydrologic data concerning rainfail-runoff relations, soil erosion, and water holding capacity are limited for this county. The objective of this study was to measure storm runoff, soil water retention curve, and soil erosion for the dominant soils in south Miami-Dade County under different water table regimes. Our results indicated that the rainfall-runoff relations were similar for the three dominant soil types (Perrine, Krome, and Chekika) when tested under a rainfall simulator. However, soil loss from Perrine soil was significantly greater than from Chekika and Krome soils as a result of fewer rock fragments and higher erodibility. In addition, Perrine soil had higher soil water content than did Chekika and Krome soils at any given tension. The results of this study should help water management planning that may result after alteration of the south Florida hydrology by restoration effects in the Everglades National Park.

Rainfall amounts and intensities increased on average in the United States during the 20th century, and according to climate change models they are expected to continue to increase during the 21st century. These rainfall changes, along with expected changes in temperature, solar radiation, and atmospheric CO2 concentrations, will have significant impacts on soil erosion rates. The processes involved in the impact of climate change on soil erosion by water are complex, involving changes in rainfall amounts and intensities, number of days of precipitation, ratio of rain to snow, plant biomass production, plant residue decomposition rates, soil microbial activity, evapo-transpiration rates, and shifts in land use necessary to accommodate a new climatic regime. This paper reviews several recent studies conducted by the authors that address the potential effects of climate change on soil erosion rates. The results show cause for concern. Rainfall erosivity levels may be on the rise across much of the United States. Where rainfall amounts increase, erosion and runoff will increase at an even greater rate: the ratio of erosion increase to annual rainfall increase is on the order of 1.7. Even in cases where annual rainfall would decrease, system feedbacks related to decreased biomass production could lead to greater susceptibility of the soil to erode. Results also show how farmers' response to climate change can potentially exacerbate, or ameliorate, the changes in erosion rates expected. C1 USDA, ARS, SW Watershed Res Ctr, Tucson, AZ 85719 USA.

One of the predicted areas for this impact is in the upper Midwest or the Corn Belt, and one concern is that current soil management practices in this region may not adequately protect the soil under these changes resulting in water quality impacts. To address this concern, this study was conducted to survey the current literature on the water quality impacts from current soil management practices and evaluate potential impacts on runoff and drainage from soil management practices under a number of precipitation scenarios. Soil management practices, e.g., crop residue, no-tilt, incorporation of manure, provide protection under today's climate. However, increasing precipitation amounts, or frequencies, rapidly decrease the effectiveness of these practices with the deleterious effect being even greater on soils with low water holding capacity and limited depth. The water quality impacts may be even more dramatic with the likelihood of increased surface runoff events. Soil management practices need to be developed and evaluated under precipitation patterns that may represent future scenarios so that producers can begin to adopt these practices into their management programs.

Output from the grain bin temperature and moisture module was used by the insect module to predict changes in insect density in 32 different bin regions. When compared to validation data from nine grain bins, the model accurately predicted insect vertical distribution and insect density. In December, the highest insect density was in the top center of the grain mass, and decreased steadily with increasing depth and towards the periphery of the grain mass. R. dominica attains this spatial distribution because immigration is primarily through the top of the bin, and higher populations occur in the interior of the grain mass because of warmer temperatures there. Initially, the model underestimated actual insect density in the grain bins. We increased the immigration rate by 50% and this resulted in a much better prediction of R. dominica density by the model. From 20 September to 14 December, populations of R. dominica increased from 0.1 to 3.5 insects per kg of wheat. Published by Elsevier Science Ltd.

Trap catch (numbers captured per week) and weekly mean grain temperature for each trap site were plotted against time and fitted to cubic polynomials, which adequately described seasonal trends. Spatial distribution of trap catch was examined by calculating the coefficient of variation, or dispersion (s(2)/m) and by constructing a contour map of trap catch values for each week. Seasonal trends in trap catch varied with species, farm, and storage season, and tended to parallel temperature trends, so that trap catch and temperature were positively correlated. Trap catch was highly aggregated except for weeks when few insects were captured. Residuals (observed-predicted values), calculated from the fitted trend curves, represent the spatial component of variation. When residuals were analyzed, the positive correlation between temperature and trap catch was usually reduced or abolished, indicating that spatial variability within any given week reflected the distribution of the population itself, rather than spatial variability in activity produced by temperature gradients. The number of insects captured by a trap is determined mainly by insect activity and the numbers present, but there are no rigorous methods for separating the immediate effect of temperature on activity from the delayed effect on population growth. However, by comparing trends in trap catch with those in temperature, it is sometimes possible to make inferences about changes in population density. Published by Elsevier Science Ltd.

(Coleoptera: Curculionidae), reared on wheat seeds were studied as a function of adult age, mating status, and nutrient availability. X-ray analysis was used to determine time of adult eclosion and the duration of development of pre-emergent weevils within the seeds, a process that lasted almost 4 days at 25degreesC and 60% r.h. There was no follicular differentiation in pre-emergent weevils. Oocyte maturation began after adults emerged from the seeds and started to feed. There was a significant increase in mean germarium length and the size of proximal follicles within the first 5 days when newly emerged weevils were mated and fed ad lib. Maximum number of follicles and mature eggs per ovariole in mated females occurred at 5-30 days of age. The number of mature eggs decreased in 60-days-old weevils, at the same time that adult mortality increased. Development of the ovarian system was much slower in unmated females than in mated females. Although there was follicle development in unmated females, ovulation never occurred and no eggs were laid. Starvation of mated females resulted in a rapid reduction in numbers of follicles and mature eggs, probably as a result of oosorption. Females were categorized into two nulliparous and three parous stages according to ovarian development and the degree of accumulation of follicular relics. Parity was directly correlated with both weevil age and the number of progeny produced and was the physiological basis used to construct an age-grading model for this species. The method will be useful for determining the age structure and reproductive potential of rice weevil populations in the field. Published by Elsevier Science Ltd.

In the first test, late instars of Tribolium castaneum (Herbst), the red flour beetle, and Tribolium confusum (du Val), the confused flour beetle, were exposed on concrete treated with hydroprene. At 40% relative humidity (r.h.), there was no difference between species regarding the percentage of individuals that stopped development in the larval stage (arrested larvae), but at 75% r.h. there were more arrested T. castaneum than T. confusum in all treatments except the low rate of formulation 202-084. No adult T. castaneum lived after emergence (live adults) at either relative humidity, but the percentage of live adult T. confusum ranged from 1.0% to 41.0%, depending on treatment. In the second test, late instars of T. confusum were exposed at 6 and 12 weeks post-treatment on concrete treated with the two experimental formulations and stored under different environmental conditions. At 6 weeks there was no difference between formulations. At 12 weeks, fewer live adults and more dead emerged adults with gross morphological deformities were found on concrete treated with formulation 202-084 and stored at 32degreesC, 75% r.h. compared to other treatment combinations. In the final experiment, wheat flour was added to treated concrete for 5 weeks before the bioassays were conducted with late-instar T. confusum. There were few live adults produced in the initial bioassays, and dead adults with gross morphological deformities ranged from 83.1% to 97.6%. However, in bioassays conducted with late-instar larvae at 6 weeks, most adults eventually emerged with few deformities. The presence of the flour apparently compromised residual control and the hydroprene was no longer effective. In summary, the new hydroprene formulations were equivalent to the registered product Gentrol((R)). Tribolium confusum was less susceptible than T. castaneum, and residual control of T. confusum on a clean surface without flour lasted about 6-12 weeks. Published by Elsevier Science Ltd.

Duration of the egg stage averaged 4.7 +/- 0.8 days with an egg hatch rate ranging from 82% to 95%. Five larval instars were determined based on head-capsule width. Total larval developmental time from egg hatch to adult emergence ranged from 42 to 47 days. Adult females began to oviposit within 12-48 h after mating with the maximum oviposition rate occurring during the first 24 h after mating. The mean (+/-SE) number of eggs laid by females was 212 +/- 34 with a range of 117-303. Application of pirimiphos-methyl, malathion, and permethrin to 30 kg lots of garlic seed failed to prevent infestation and bulb damage by the larvae. However, compared with controls, the percentage of damaged bulbs and the number of larvae detected during 12 weeks of storage was smaller on garlic treated with four doses of pirimiphos-methyl.

The 42 kGy (kilo Gray) dose irradiated DOV and Thompson seedless raisins incubated in five growth media were shown to be free of microorganisms. The quantity of TCA in the irradiated raisins was 0.39 +/- 0.05 ng/kg compared with 0.56 +/- 0.17 ng/kg in nonirradiated samples. The observation supports the view that raisins biosynthesize a minute but detectable quantity of TCA. The SPME fiber (divinylbenzene/carboxen/polydimethylsiloxane) method was simpler and quicker than the Likens-Nickerson extraction method for TCA determination. The biochemical mechanism of TCA production in raisin grape is unknown, but information in the biochemical literature of abundant phenolic substrates in grape berry, the presence of methyltransferases in Vitis tissues and of a chlorinating system provides a plausible basis for further investigation of the process.

In the first test, application rates of 10-ppm R,S-methoprene (a racemic mixture of the R and S isomers of methoprene) and 1 and 5-ppm S-methoprene (S-isomer only) gave 100% suppression of F-1 adult progeny of R. dominica for 24 weeks. In the second test, adult R. dominica were exposed at 27degreesC and 32degreesC, 57% and 75% relative humidity (r.h.) on untreated wheat and wheat treated with 1- to 10-ppm S-methoprene dust. Survival after a 3-week exposure decreased with increasing concentration of dust, and ranged from 69% to 99%, but no F-1 adult progeny were produced in treated wheat. In the final test, concentrations of 0, 0.25, 0.50, 0.75, and 1.0 ppm S-methoprene EC were combined with concentrations of 0, 75, 150, 225, and 300 ppm of the commercial diatomaceous earth (DE) Protect-It(R). Within each methoprene concentration, survival generally decreased with increasing concentration of DE, and was generally greater at 75% than at 57% r.h. Only the wheat treated with 0-ppm methoprene contained an appreciable number of F-1 adults. In summary, both the dust and EC formulations of S-methoprene gave 100% suppression of F-1 adult progeny R dominica at application rates of 1 ppm, and combination treatments involving reduced rates of methoprene and DE gave effective control of R. dominica.

A second series of tests was conducted on hard winter wheat using S. oryzae (L.), the rice weevil, Rhyzopertha dominica (F.), the lesser grain borer, and T. castaneum. Mortality of all species on both commodities generally increased with insecticide concentration, exposure interval, and temperature, and data were described by linear and non-linear regressions with concentration as the independent variable. Mortality of S. zeamais ranged from 58% to 90% on maize treated with 0.5 ppm thiamethoxam, and approached 95-100% as concentration increased to 4 ppm. Oryzaephilus surinamensis appeared to be slightly less susceptible than S. zeamais; mortality ranged from about 18 % to 80 % at 5 ppm and there was a more gradual increase in mortality as concentration increased. Mortality of T. castaneum generally did not exceed 40% at any concentration unless the beetles were exposed for 6 d. Mortality of R. dominica and S. oryzae was less than 60% when exposed on treated wheat for 1 and 2 d, but increased to nearly 100% when exposed for 6 d at 27degreesC and 32degreesC. Mortality of T. castaneum did not exceed 20% at the 1- and 2-d exposures, and approached 100 % only when beetles were exposed for 6 d at 32degreesC. Few F-1 adults of any species were found in treated maize or in treated wheat but the number of F-1 T. castaneum in untreated maize and untreated wheat was very low compared with the other species.

(Lepidoptera: Tortricidae), in various commodities. Thermal treatments are gaining acceptance to replace chemical fumigation. Determining the most thermal-tolerant life stage is essential in the development of effective postharvest insect control protocols based on thermal energy. A heating block system was used to evaluate relative heat resistance of five different life stages of codling moth: white-ring eggs, black-head eggs, third-instar, fifth-instar, and diapausing larvae, at a heating rate of 15degreesC/min. The fifth-instar was the most heat-resistant life stage in the tested temperature range of 50-52degreesC except for diapausing larvae. Thermal death kinetic data of diapausing fifth-instar larvae were determined and also compared with the published TDT curve of non-diapausing larvae using the same heating block system. Both diapausing and non-diapausing larvae were dead after treatments at 50degreesC for 5 min and 52degreesC for 2 min. However, at the lower temperatures or shorter times, diapausing larvae had lower mortality than non-diapausing larvae. (C) 2004 Elsevier Ltd. All rights reserved.

Returns are from 46 different US states and Canada. Survey responses provide information on farm background characteristics, production systems, and marketing. Results show consensus on many points, and diversity on many others. The structure of the pasture-finished beef enterprise is built on direct marketing, niche marketing, Source identification, value added, and rising consumer consciousness of health, environmental, and social benefits. There is a need for more attention to the role of animal husbandry in sustainable agriculture. Recent years have seen renewed interest in grazing systems, and a growth in market demand for pasture-finished beef. This is can be seen in popular press and consumer trends. The industrial food system does not take good advantage of the natural characteristics of cattle. In traditional farming systems, cattle perform the useful work of harvesting and concentrating nutrients from outlying pasturelands and transporting them to the human homestead or household. Cattle grazing can be accomplished with minimal material and management inputs. (c) 2004 by The Haworth Press, Inc. All rights reserved. C1 W Virginia Univ, Extens Serv, Morgantown, WV 26506 USA.

Three cultivars were identified with high leaf P concentrations, three with low concentrations, and one with very high leaf P. Results suggest that breeders should initially be able to develop cultivars that remove an additional 4.5 kg P ha(-1) yr(-1) from EAA sugarcane fields.

To use water efficiently in crop production, knowledge about crop responses to irrigation water, or the production function, is essential. In this paper, we estimated six production functions, two N-fertilizer treatments for each year in 1999, 2000, and 2001, for corn production using the data from experimental plots in Florence, South Carolina, USA. Optimal levels of irrigation and gross margins under profit-maximizing and yield-maximizing strategies were computed. The results indicate that at the current prices of corn and water in South Carolina, the profit-maximizing strategy conserved more irrigation water and produced larger gross margins than the yield-maximizing strategy. The differences in optimal levels of irrigation water and gross margins between the two strategies became even more significant when the relative water/corn price ratios increased. To find out how demand for irrigation water responds to changes in water prices, demand functions for water were derived and demand elasticities of water were computed. At the current prices of water and corn, the demand elasticities were inelastic, which means that irrigation is not very responsive to changes in the price of water. As the price of water increased, demand for irrigation became more responsive to changes in water prices. C1 USDA ARS, Sustainable Agr Syst Lab, Beltsville, MD 20705 USA.

To use these inputs efficiently, knowledge about plant responses to N-fertilizer and irrigation water, or production functions, is essential. Corn production functions were estimated using the data from experimental plots in Florence, South Carolina, U.S.A., from 1999 through 2001. There were three irrigation treatments and four N-fertilizer regimes. Several forms of production functions were fitted to the data and the quadratic form of the production function was found to have the best fit for the data. The estimated production functions were then used to determine the optimal levels of water and N-fertilizer applications under both yield-maximizing and profit-maximizing strategies. Results indicate that the yield-maximizing strategy called for more water and N-fertilizer and yielded smaller net returns than the profit-maximizing strategy. In 1999, for example, under the current average prices old corn, water, and N-fertilizer, the yield-maximizing strategy required 667 ha-mm of water and 224 kg of N-fertilizer to produce 10.4 Mg/ha of corn and $5.42 of net returns; whereas the profit-maximizing strategy required only 556 ha-mm of water and 174 kg of N-fertilizer to produce 9.87 Mg of corn and $57.38 of net returns. The least-cost combinations of water and N-fertilizer application levels for a given output were also determined. The results provide useful information to farmers to make N-fertilizer and irrigation decisions for profit maximization and for resource conservation.

Soybean crops have been recognized as deficient in supplying crop residues that reduce soil erosion. A new type of soybean tested at the Beltsville Agricultural Research Center, Maryland, can grow to heights of 1.8-meters (6 ft) or more. The development of the large biomass soybean (LBS) suggested the potential of increased crop residue production to reduce soil loss on erodible soybean lands. An evaluation was conducted of the soil conservation benefits of LBS versus conventional soybean using data from a three-year field experiment. LBS produced more crop residue dry biomass and provided a mean increase of 31 percent more crop residue cover in the spring before mulch tillage and 47 percent more after mulch tillage than conventional cultivars. Soil loss estimates for LBS were much lower than for conventional soybeans as simulated by a revised universal soil loss equation (RUSLE). Breeding for increased residue production in soybeans could produce significant environmental benefits as a soil conservation practice in reducing soil erosion. The conservation benefits of LBS can be realized if enhanced biomass production can be combined with adequate grain production. C1 USDA ARS, BARC W, Beltsville, MD 20705 USA.

DESIGN: Cross-sectional surveys. SETTING: Nationally representative surveys using data from the U.S. Census, Third National Health and Nutrition Examination Survey, and National Medical Care and Utilization Expenditure Survey. PARTICIPANTS: Representative samples of U.S. adults aged 60 and older. MEASUREMENTS: The healthcare costs of sarcopenia were estimated based on the effect of sarcopenia on increasing physical disability risk in older persons. In the first step, the healthcare cost of disability in older Americans was estimated from national surveys. In the second step, the proportion of the disability cost due to sarcopenia (population-attributable risk) was calculated to determine the healthcare costs of sarcopenia. These calculations relied upon previously published relative risk values for disability in sarcopenic individuals and sarcopenia prevalence rates in the older population. RESULTS: The estimated direct healthcare cost attributable to sarcopenia in the United States in 2000 was $18.5 billion ($10.8 billion in men, $7.7 billion in women), which represented about 1.5% of total healthcare expenditures for that year. A sensitivity analysis indicated that the costs could be as low as $11.8 billion and as high as $26.2 billion. The excess healthcare expenditures were $860 for every sarcopenic man and $933 for every sarcopenic woman. A 10% reduction in sarcopenia prevalence would result in savings of $1.1 billion (dollars adjusted to 2000 rate) per year in U.S. healthcare costs. CONCLUSION: Sarcopenia imposes a significant but modifiable economic burden on government-reimbursed healthcare services in the United States. Because the number of older Americans is increasing, the economic costs of sarcopenia will escalate unless effective public health campaigns aimed at reducing the occurrence of sarcopenia are implemented.

Triolein, the major component of olive oil, canola oil, and other dietary oils, was heated at frying temperature, and the TAG oxidation products were separated using RP-HPLC coupled to an ion trap mass spectrometer via an electrospray ionization interface. Ammonium formate was added as a sheath liquid to promote ammonium adduct formation. Masses corresponding to ammonium adducts of intact carbon-linked dinners (m/z 1783-1787), trimers (m/z 2666-2672), and tetramers (m/z 3547-3557) of triolein, with and without additional sites of unsaturation, were observed. Also, dinners, trimers, and tetramers containing one, two, or three additional oxygens, also with and without additional sites of unsaturation, are reported. Based on the formation of some types of triolein dinners, we believe that tristearin might also form dinners, even though it has no readily oxidizable sites of unsaturation. Oxidized tristearin monomers, tristearin dinners, chain-addition products, and chain-shortened products are observed. C1 Florida Atlantic Univ, Dept Chem & Biochem, Boca Raton, FL 33431 USA.

The purpose of this study was to relate genotypic differences in seed nitrogen accumulation with genomic regions controlling nitrogen accumulation in soybean during R-5, R-6, and R-7 growth stages. A population of 101 F-6:8 recombinant inbred lines (RIL) developed from a cross of N87-984-16 x TN93-99 was utilized. The RIL were grown at the University of Tennessee, Knoxville Experiment Station, in a randomized complete block design with three replications in 2002. Seed nitrogen was determined from pod samples harvested at the R-5, R-6, and R-7 growth stages. A significant (P < 0.05) difference among genotypes was found for nitrogen accumulation at all three growth stages. Single-factor ANOVA revealed that quantitative trait loci (QTL) governing nitrogen accumulation in soybean seed were distributed in the linkage groups A2, B2, D1a, D1b, E, G, and M. Phenotypic variation explained by an individual QTL ranged from 5 to 11.6%. These QTL may provide useful marker-assisted selection opportunities for soybean protein improvement.

Initial experiments demonstrated that the lipid in commercially produced soy flakes was readily transesterified during agitation at 60 degreesC in sealed containers of alcoholic NaOH. Methyl, ethyl, and isopropyl alcohols readily participated in the reaction, suggesting that the phenomenon is a general one. Statistical experimental design methods and response surface regression analysis were used to optimize reaction conditions, using methanol as alcohol. At 60 degreesC, the highest yields of methyl ester with minimal contamination by FFA and AG were predicted at a molar ratio of methanol/AG/NaOH of 226:1:1.6 with an approximately 8-h incubation. An increase in the amount of methanol, coupled with a reduced alkali concentration, also gave high ester yields with low FFA and AG contamination. The reaction also proceeded well at 23 degreesC (room temperature), giving higher predicted ester yields than at 60 degreesC. At room temperature, maximal esterification was predicted at a molar ratio of 543:1:2.0 for methanol/AG/NaOH, again in 8 h. Of the lipid in soy flakes, 95% was removed under such conditions. The amount of FAME recovered after in situ transesterification corresponded to 84% of this solubilized lipid. Given the 95% removal of lipid from the soy flakes and an 84% efficiency of conversion of this solubilized lipid to FAME, one calculates an overall transesterification efficiency of 80%. The FAME fraction contained only 0.72% (mass basis) FFA and no AG. Of the glycerol released by transesterification, 93% was located in the alcoholic ester phase and 7% was on the post-transesterification flakes. C1 USDA ARS, ERRC, Wyndmoor, PA 19038 USA.

In this study, a Ta Tao #6 interstem significantly retarded bloom of `Springcrest' and `Harvester' peach, averaging nearly 8 days delay. Significant freeze events occurred in two of the four cropping years observed. However, the bloom delay provided by a Ta Tao #6 interstem was sufficient in only one of these events to significantly improve fruit yield. Attempts to close a harvest gap between `Harvester' and `Redglobe' peach cultivars by altering fruit maturation were only partially successful. Fruit maturation of `Harvester' and `Springcrest' on Ta Tao #6 interstem trees was delayed on average 3.6 days over the 3 cropping seasons observed when compared to that of their 2-piece counterparts on Lovell seedling rootstock without the interstem. However, 2-piece trees of `Redglobe' on Halford seedling rootstock failed to advance maturation compared to their counterparts on Lovell rootstock and the net shift in the harvest window of `Harvester' peach was insufficient to close the 11-12 day gap observed between the two cultivars. Nevertheless, the use of Ta Tao interstems to delay bloom and fruit maturation may offer growers a useful tool to manage their spring frost risk and harvest management.

Development of resistant lettuce cultivars has been hindered by the difficulty of evaluating resistance in field tests and the lack of a screening procedure that reliably predicts field performance. Several lettuce genotypes of diverse geographic origin and plant architecture including modern and heirloom cultivars, plant introduction accessions, and breeding lines, were evaluated for resistance to S. minor using several methods. Resistance was evaluated in fields that contained naturally occurring S. minor, in a field that contained both naturally occurring and manually incorporated S. minor inoculum, and in the greenhouse using two types of inocula. Many genotypes exhibited partial resistance to S. minor, with significantly reduced disease incidence relative to susceptible controls. The similarity of disease ratings observed in replicated field tests supports the conclusion that partial resistance is under genetic control. Ratings obtained in some greenhouse tests were highly correlated with field ratings, but this was not true for all tests. Therefore, although greenhouse evaluation with adequate replication and repetition can be used as a selection tool, field testing remains an essential component of S. minor resistance breeding programs.

In addition, the relationship between external and internal fruit color and firmness was determined. 1-MCP reduced the rate of red color development in fruit of all stages of ripeness. A single application of 1-MCP delayed color development by approximate to6 days. A second application of 1-MCP 10 days after first treatment additionally delayed color development of mature green fruit by another 8 to 10 days. Continuous 1-MCP application completely inhibited color development of breaker and half-ripe fruit for the duration (34 days) of application, but only partially inhibited firmness loss. When fruit at 50% color development were treated with 1-MCP, gel color development tended to lag behind the external fruit color change compared to nontreated fruit. Some aroma volatiles were affected by 1-MCP applied at the mature green and breaker stages, but the effect was relatively minor; 1-MCP did not affect sugar or titratable acid levels in these fruit. Collectively, the data indicate 1-MCP caused minor shifts in the quality attributes of locule color, aroma, and firmness relative to external color, which may reduce the value of this treatment, but benefits accrued by slowed firmness loss and color development may afford sufficient compensation to make 1-MCP application commercially feasible.

Parent selection in hop breeding on the basis of heterotic potential has not been reported in literature even though dominance has been reported in hops for several economically important traits. The objectives of this study were to determine if amplified fragment length polymorphism (AFLP)-based genetic distance among mate and female accessions accurately reflect pedigree relationships and present information on potential heterotic crosses in hop. Nineteen cultivars were analyzed for genetic distance to 82 male accessions representing the assumed diversity of U.S. hops. Genetic distances (GD) between male/female pairs were estimated using AFLP (490 polymorphic bands). Distance estimates comparing males with females ranged from 0.169 to 0.62 with an overall average of 0.306. For each hop female, the 10 most genetically diverse and 10 most genetically similar males were identified and grouped. Coefficients of coancestry (COA) for each male/female pair within these groups were calculated using pedigree analysis. Values of COA for the genetically similar pairs (COA(avg) = 0.046) were significantly higher than the COA for the diverse pairs (COA(avg) = 0.013), suggesting that choosing male/female pairs on the basis of AFLP-based genetic distance may predict heterotic potential in crosses when GD >0.36.

The 2002 Midwestern crop provided a unique opportunity to evaluate PHS methodology because a large amount of sprouted samples from a limited varietal and geographic base were available. Approximately 30% of the samples collected in Minnesota and northern districts of North Dakota were sprouted. All samples (N = 285) were evaluated by pearling and stirring number (SN), while smaller subsets were utilized for the other methodology. Falling number and SN were most sensitive for the detection of low levels of PHS. Pearling and staining with fluorescein dibutyrate were less sensitive to low levels of PHS. The measure of conductivity was found not strongly related to other measures of PHS. Samples were stored at similar to20degreesC for up to 11 months following harvest. A decline in the germinative energy (GE) of some samples was observed and. in general, this was most severe for sprouted samples. While significant correlations were observed between GE and measures of PHS, in no case was a correlation of a magnitude where a measure of preharvest sprouting alone could be used to predict seed storability with an acceptable degree of accuracy.

Fumonisins were originally isolated as environmental tumor promoters, and they remain a concern because they are frequent contaminants of corn-derived food products intended for direct human consumption. FB(1) inhibits ceramide synthase, which may account for its acute toxic effects, but understanding of its tumor promotion mechanism has been limited by the general lack of understanding in the field. There is no evidence for functional metabolism of fumonisins in mammals, but abiogenic conversions during food processing are a concern because some known conversion products retain biological activity, including hydrolyzed FB(1) (HFB(1)). HFB(1), formed by alkaline removal of FB(1) side chains, is a frequent contaminant of lime-treated corn products such as tortillas and tortilla chips. Humpf et al. (J. Biol. Chem., 273, 19060, 1998) observed that HFB(1) not only inhibits ceramide synthase, but it is converted to a ceramide analog with about ten times the in vitro mammalian toxicity of intact FB(1). In the present study we have confirmed this observation by preparing a series of ceramide analogs of HFB(1) with varying fatty acid chain lengths and degree of unsaturation. Optimal in vitro mammalian toxicity was observed with fatty acid chain lengths of 10- 14 carbons. However, ceramide analogs of HFB(1) were not phytotoxic in vitro, and ceramide analogs of FB(1) were not toxic in either mammalian or plant in vitro bioassays.

Risk of exposure is examined in a global context comparing risk of toxin exposure by levels of national socioeconomic development. Then risk of exposure is reexamined in the context of agro-ecology, distribution of toxigenicity of Aspergillus flavus, and social factors that influence food management practices. The effects of aflatoxin exposure on human health are explored in three sections: human disease and nutritional status, carcinogenicity, and child growth and development. The section concerning mitigation of the effects of aflatoxin on human health contrasts efficacy of regulation, food basket modification, and production-side agriculture intervention. It is concluded that risk of hepatocellular carcinoma in developing countries, such as West Africa, may be addressed by vaccination for hepatitis B virus (HBV) and other public health options. Young children in West Africa who are chronically exposed to aflatoxin in foods and who consume nutritionally deficient diets have been shown to be stunted and underweight, as measured by World Health Organization (WHO) Z-scores.

Contamination is monitored in developed countries using enzyme-linked immunusorbent assay (ELISA)- and high-performance liquid chromatography (HPLC)-based assays, both of which may be too expensive for routine use in many developing countries. There is a need for inexpensive alternative approaches to detect aflatoxins in lots of foods and feeds. Reviewed here are culture-based methods that determine if a sample is contaminated with aflatoxigenic fungi. These approaches include 1) blue fluorescence of aflatoxin B(1), particularly when enhanced by including beta-cyclodextrin in the culture medium, 2) yellow pigment production, and 3) color change on exposure to ammonium hydroxide vapor. The presence of aflatoxin B(1) can be detected by its blue fluorescence, which is enhanced when the toxin complexes with the hydrophobic pocket of beta-cyclodextrin. The yellow pigment and ammonium hydroxide vapor tests are based on the production of yellow anthraquinone biosynthetic intermediates in the aflatoxin pathway. These compounds act as pH indicator dyes, which are more visible when they have turned red at alkaline pH. Because these tests are based on two different mechanisms, it has been possible to combine them into a single test. In a study of 517 A. flavus isolates from the Mississippi Delta, the combined assay reduced false positives for aflatoxigenicity to 0%, and false negatives to 7%. The increased predictive power of the combined cultural assay may enable its use for inexpensively identifying potential aflatoxin contamination in feeds and foods.

Method development has followed a process somewhat akin to Darwinian evolution: methods are selected based upon the characteristics most desirable to the analyst. Typically, this has lead to the development of accurate and sensitive methods for their detection, with a recurring emphasis on improving the speed and lowering the costs of the assays. Like evolution, there have been radical developments, incremental developments, and techniques that have fallen from favor only to be rediscovered. This review focuses on recent developments in technologies for detection of mycotoxins, with a particular emphasis on the myriad forms of biosensors that have begun to appear. Specifically, recent development in evanescent wave technologies (surface plasmon resonance, fiber optic sensors), lateral flow and dipstick devices, fluorescence polarization and time-resolved fluorescence, microbead assays, and capillary electrophoretic immunoassays, are described. The challenge for the emerging technologies is to demonstrate advantages over the more conventional, and better established, techniques in settings outside the analytical laboratory.

Fungal processes necessary for invasion of the plant and production of aflatoxin can be broken down into three categories: 1) cell wall degradation (cellulases, pectinases, amylases, and proteinases), 2) fungal development (cell wall synthesis and conidiophore and conidial formation), and 3) aflatoxin biosynthesis and regulation. Fungal expressed sequence tag (EST) projects have led to a rapid expansion in the number of candidate genes governing the processes involved in invasion of the plant and aflatoxin contamination. Plant factors have been discovered through the use of proteomics and natural product chemistry that may influence fungal processes involved in invasion and aflatoxin contamination. These factors can also be divided into three categories: 1) seed proteins/inhibitors of fungal cell wall degrading enzymes, 2) seed/kernel natural products that may influence fungal growth and/or aflatoxin synthesis, and 3) plant stress-responsive proteins. If the interaction between the plant and the fungus can be better understood through use of proteomics, genomics, and natural product chemistry, particularly in how plant factors may influence fungal processes contributing to virulence and aflatoxin contamination, this information could accelerate development of breeding through marker selection and/or gene insertion technologies for enhancing host plant resistance.

Studies of resistance to aflatoxin accumulation in grain and Aspergillus ear rot began in 1988 with experiments designed to address fundamental needs of a new breeding program. Through the 1990s, diverse inbred lines, test crosses, and segregating populations were developed and evaluated for resistance in numerous environments. Concerns of industry inspired researchers to initiate an accelerated program for resistance to fumonisin accumulation in grain and Fusarium ear rot in the late 1990s. Present research in both programs is directed with the latest molecular marker technology, and is focused on incorporating novel genes for resistance from diverse sources into elite inbred lines that impart high yield to hybrid performance. With continued funding, agronomically superior sources of resistance along with information on molecular markers associated with resistance soon may be released.

Of the many research approaches being studied to reduce and, ultimately, eliminate aflatoxin contamination, biological control is one of the more promising, particularly for the near-term. Numerous organisms have been tested for biological control of aflatoxin contamination including bacteria, yeasts, and nontoxigenic strains of the causal organisms, Aspergillus flavus and A. parasiticus. Most of the field successes to date have been achieved by applying certain nontoxigenic strains of A. flavus and A. parasiticus to soil of susceptible crops, such as peanuts, cotton, and corn. The applied strains occupy the same niche as the naturally occurring toxigenic strains and competitively exclude them when crops are susceptible to infection. Various formulations have been used to apply the nontoxigenic strains to soil, but the most effective methods have been to combine the desired strain with a carrier/substrate, such as a small grain. This was done either by minimally growing the desired strain on sterilized grain or by coating the surface of the grain with conidia of the strain. After application to the field and uptake of moisture, the fungus completely colonizes the grain, and abundant sporulation provides inoculum levels sufficient to achieve a competitive advantage for the nontoxigenic strain. In several years of field studies, particularly with peanuts and cotton, significant reductions in aflatoxin contamination in the range of 70-90% have been achieved consistently. Two separate products have recently received EPA registration as biopesticides to control aflatoxin contamination in cotton (AF36) and peanuts (afla-guard(R)).

A second objective was to ascertain whether ovariectomy (estrogen deficiency) alters the effects of low dietary silicon on bone formation. Female rats weighing about 56 g were assigned to groups of 10 in a factorially arranged experiment. The variables were suppiemental dietary silicon at 0 or 35 mg/kg and ovariectomy (estrogen-deficient) or sham operation at the start of the experiment. The basal silicon-low diet contained about 2 mg Si/kg. Low dietary silicon compared with adequate silicon decreased plasma osteopontin concentration, increased plasma sialic acid concentration, and increased urinary helical peptide excretion. Low dietary silicon also affected the response to estrogen deficiency. Ovariectomy increased plasma alkaline phosphatase in the silicon-supplemented, but not in the silicon-low rats. In contrast, ovariectomy decreased liver ornithine aminotransferase in silicon-low but not in silicon-supplemented rats. Ovariectomy increased the urinary excretion of deoxypyridinoline and decreased the femur concentration of sialic acid more markedly in silicon-supplemented than silicon-low rats. Silicon and an interaction between silicon and ovariectomy only mildly changed bone strength and physical measurements and did not affect femur calcium concentration. The findings suggest that silicon has a biochemical function that affects bone growth processes before bone crystal formation by affecting bone collagen turnover and sialic acid-containing extracellular matrix proteins such as osteopontin.

As well, M. bovis infection was identified in free-ranging white-tailed deer in northeast Michigan in 1995. Tuberculosis in both captive and free-ranging Cervidae represents a serious challenge to the eradication of M. bovis infection from the United States. Currently, the only approved antemortem tests for tuberculosis in Cervidae are the intradermal tuberculin skin test and the blood tuberculosis test (BTB). At present, the BTB is not available in North America. Tuberculin skin testing of Cervidae is time-consuming and involves repeated animal handling and risk of injury to animals and humans. This study evaluated the potential of a new blood-based assay for tuberculosis in Cervidae that would decrease animal handling, stress, and losses due to injury. In addition, a blood-based assay could provide a more rapid diagnosis. Twenty 6-9-month-old white-tailed deer, male and female, were experimentally inoculated by instillation of 300 colony-forming units of M. bovis in the tonsillar crypts. Seven, age-matched uninfected deer served as controls. Blood was collected on days 90, 126, 158, 180, 210, 238, 263, and 307 after inoculation and was analyzed for the production of interferon-gamma (IFN-gamma) in response to incubation with M. bovis purified protein derivative (PPDb), M.-avium PPDa, pokeweed mitogen (PWM), or media alone. Production of IFN-gamma in response to PPDb was significantly greater (P < 0.05) at all time points in samples from M. bovis-infected deer as compared with uninfected control deer, whereas IFN-gamma production to PWM did not differ significantly between infected and control deer. Measurement of IFN-gamma production to PPDb may serve as a useful assay for the antemortem diagnosis of tuberculosis in Cervidae. C1 USDA, Natl Anim Dis Ctr, ARS, Ames, IA 50010 USA.

At present, fecal culture remains the single diagnostic test that can detect infection in both disease states provided the animals actively shed Mycobacterium paratuberculosis in their feces. Yet, fecal culture has a disadvantage associated with the protracted incubation period of 8-16 weeks before results are available. Detection of nucleic acids specific to M. paratuberculosis in fecal samples is a technique that can circumvent the culture method. This study describes a rapid, simple, and effective method to extract DNA from fecal samples and modification of a polymerase chain reaction assay for optimal sensitivity of detection. An evaluation of 1,000 well-characterized fecal samples was performed by the Colorado Department of Agriculture (Denver, CO) and the National Animal Disease Center (Ames, IA) to determine the sensitivity, specificity, and reproducibility of the new method. Results from this study show that the sensitivity of detection was highly dependent on the load of bacteria in the fecal sample with 81% detection of samples containing >70 colony-forming units (cfu)/g of feces and a 45% detection rate for samples containing less than 1 cfu/g. Similarly, reproducibility of the technique between the 2 laboratories (n = 250 samples) was much higher (75%) for the fecal samples containing high levels of M. paratuberculosis and reduced to 25% for samples with less than I cfu/g. An overall specificity of 83% was obtained for known negative samples. The method described here is rapid, simple, and inexpensive compared with other techniques. In addition, this method can detect animals that are shedding less than I cfu/g. C1 USDA ARS, Natl Anim Dis Ctr, Ames, IA 50010 USA.

One uninoculated raccoon kit served as a control. All 4 animals in the TME-inoculated group showed clinical signs of neurologic disorder and were euthanized between 21 and 23 weeks postinoculation (PI). Necropsy examinations revealed no gross lesions. Spongiform encephalopathy was observed by light microscopy, and the presence of protease-resistant prion protein (PrPres) was detected by immunohistochemistry and Western blot techniques. Scrapie-associated fibrils were observed by negative-stain electron microscopy in the brains of 3 of the 4 inoculated raccoons. These findings confirm that TME is experimentally transmissible to raccoons and that diagnostic techniques currently used for TSE in livestock detect prion protein in raccoon tissue. According to previously published data, the incubation period of sheep scrapie in raccoons is 2 years, whereas chronic wasting disease (CWD) had not shown transmission after 3 years of observation. Because incubation periods for the 3 US TSEs (scrapie, TME, and CWD) in raccoons appear to be markedly different, it may be possible to use raccoons for differentiating unknown TSE agents. Retrospective genotyping of raccoons using frozen spleens showed that the raccoon PrP gene is identical to the mink gene at codons 179 and 224. Further studies, such as the incubation periods of bovine spongiform encephalopathy and other isolates of scrapie, CWD, and TME in raccoons, are needed before the model can be further characterized for differentiation of TSE agents.

Here we report the genomic sequences and comparative analysis of BPSV strain BV-AR02 and ORFV strains OV-SA00, isolated from a goat, and OV-IA82, isolated from a sheep. Parapoxvirus (PPV) BV-AR02, OV-SA00, and OV-IA82 genomes range in size from 134 to 139 kbp, with an average nucleotide composition of 64% G+C. BPSV and ORFV genomes contain 131 and 130 putative genes, respectively, and share colinearity over 127 genes, 88 of which are conserved in all characterized chordopoxviruses. BPSV and ORFV contain 15 and 16 open reading frames (ORFs), respectively, which lack similarity to other poxvirus or cellular proteins. All genes with putative roles in pathogenesis, including a vascular endothelial growth factor (VEGF)-like gene, are present in both viruses; however, BPSV contains two extra ankyrin repeat genes absent in ORFV. Interspecies sequence variability is observed in all functional classes of genes but is highest in putative virulence/host range genes, including genes unique to PPV. At the amino acid level, OV-SA00 is 94% identical to OV-IA82 and 71% identical to BV-AR02. Notably, ORFV 006/132, 103, 109, 110, and 116 genes (VEGF, homologues of vaccinia virus A26L, A33R, and A34R, and a novel PPV ORE) show an unusual degree of intraspecies variability. These genomic differences are consistent with the classification of BPSV and ORFV as two PPV species. Compared to other mammalian chordopoxviruses, PPV shares unique genomic features with molluscum contagiosum virus, including a G+C-rich nucleotide composition, three orthologous genes, and a paucity of nucleotide metabolism genes. Together, these data provide a comparative view of PPV genomics. C1 USDA ARS, Plum Isl Anim Dis Ctr, Greenport, NY 11944 USA. Univ Buenos Aires, Sch Vet Sci, RA-1427 Buenos Aires, DF, Argentina.

The 365-kbp CNPV genome contains 328 potential genes in a central region and in 6.5-kbp inverted terminal repeats. Comparison with the previously characterized fowlpox virus (FWPV) genome revealed avipoxvirus-specific genomic features, including large genomic rearrangements relative to other chordopoxviruses and novel cellular homologues and gene families. CNPV also contains many genomic differences with FWPV, including over 75 kbp of additional sequence, 39 genes lacking FWPV homologues, and an average of 47% amino acid divergence between homologues. Differences occur primarily in terminal and, notably, localized internal genomic regions and suggest significant genomic diversity among avipoxviruses. Divergent regions contain gene families, which overall comprise over 49% of the CNPV genome and include genes encoding 51 proteins containing ankyrin repeats, 26 N1R/p28-like proteins, and potential immunomodulatory proteins, including those similar to transforming growth factor beta and beta-nerve growth factor. CNPV genes lacking homologues in FWPV encode proteins similar to ubiquitin, interleukin-10-like proteins, tumor necrosis factor receptor, PIR1 RNA phosphatase, thioredoxin binding protein, MyD116 domain proteins, circovirus Rep proteins, and the nucleotide metabolism proteins thymidylate kinase and ribonucleotide reductase small subunit. These data reveal genomic differences likely affecting differences in avipoxvirus virulence and host range, and they will likely be useful for the design of improved vaccine vectors.

As MDV is serially passaged in cell culture, the virus becomes attenuated and the number of copies of the 132-bp repeat increases from 2 to often more than 20 copies. To determine the role of the repeats in attenuation, we used five overlapping cosmid clones that spanned the MDV genome to reconstitute infectious virus (rMd5). By mutating the appropriate cosmids, we generated clones of infectious MDVs that contained zero copies of the 132-bp repeats, rMd5(0132); nine copies of the 132-bp repeats, rMd5(Delta132); and nine copies of the 132-bp repeats inserted in the reverse orientation, rMd5(rev9-132). After two passages in cell culture, wild-type Md5, rMd5, and rMd5(Delta132) were stable. However, rMd5(9-132) and rMd5(rev9-132) contained a population of viruses that contained from 3 to over 20 copies of the repeats. A major 1.8-kb mRNA, containing two copies of the 132-bp repeat, was present in wild-type Md5 and rMd5 but was not present in rMd5(Delta132), rMd5(9- 132), rMd5(rev9-132), or an attenuated MDV. Instead, the RNAs transcribed from the 132-bp repeat region in rMd5(9-132) and rMd5(rev9-132) closely resembled the pattern of RNAs transcribed in attenuated MDVs. When inoculated into susceptible day-old chicks, all viruses produced various lesions. Thus, expansion of the number of copies of 132-bp repeats, which accompanies attenuation, is not sufficient in itself to attenuate pathogenic MDVs.

In Michigan, the ability to estimate the true prevalence of bovine tuberculosis (TB; caused by Mycobacterium bovis) in free-ranging white-tailed deer (Odocoileus virginianus) will become increasingly important to accurately assess progress towards eradication. Our objectives were threefold: to estimate the true prevalence of M. bovis in free-ranging deer in Michigan, to evaluate the effectiveness of existing TB surveillance methods, and to indirectly assess whether TB epidemiologic data from captive cervid herds can be meaningfully extrapolated to free-ranging populations. The study population consisted of all free-ranging deer submitted for TB testing in 2001 from six townships in northeastern Lower Michigan. Tissue samples of tonsil and cranial lymph nodes were collected bilaterally from all deer eligible for the study that did not have gross lesions suggestive of TB (n=701). Samples were subjected to histopathologic, acid-fast (AF) staining, mycobacterial culture, and polymerase chain reaction (PCR) testing. Seven deer cultured positive for M. bovis that would not have been detected by current surveillance, yielding apparent and true prevalence estimates (95% confidence limits) of 2.7% (1.6, 3.8) and 3.6% (2.3, 4.9), respectively. The sensitivity, specificity and positive and negative predictive values of the current surveillance protocol were 75, 100, 100, and 99%, respectively. Histologic lesions were present only in tonsils, and ranged from simple necrosis to caseation, suppuration, and granuloma formation. Acid-fast staining and PCR detected M. bovis in only one of the seven culture-positive deer. Our study provides the first estimate of the true prevalence of M. bovis in Michigan's free-ranging deer population and suggests modest underestimation of that prevalence by current surveillance. This study also suggests that caution is warranted when extrapolating epidemiologic data on TB in captive cervids to free-ranging populations and confirms the pivotal role of the tonsil in early infections.

In vitro proliferative and interferon-gamma (IFN-gamma) responses to M. bovis purified protein derivative (PPD) were detected beginning 9 days postvaccination. Responses to Mycobacterium avium PPD, however, generally exceeded responses to M. bovis PPD. Interferon-gamma responses to M. avium PPD were not detected prior to vaccination nor in nonvaccinated deer, suggesting that vaccination with BCG boosted prior quiescent M. avium-sensitized cells. Both CD4(+) and gammadelta T cells from vaccinated deer proliferated in response to M. bovis PPD stimulation. Intradermal administration of M. bovis PPD resulted in increases in skin thickness of vaccinated deer beginning 24 hr postinjection. Such early reactions were characterized by edema and minimal mononuclcar cell infiltration, whereas later reactions (i.e., 72 hr postinjection) were more typical of delayed type hypersensitivity. Upon in vitro activation with pokeweed mitogen, CD44 expression increased and CD62L expression decreased on lymphocytes from deer regardless of vaccination status. Likewise, M. bovis PPD stimulation of lymphocytes from vaccinated deer resulted in increases in CD44 expression and decreases in CD62L expression. These findings demonstrate the potential of BCG vaccination to elicit strong cell-mediated immune responses and appropriate alterations in CD44 and CD62L expression with in vitro stimulation of white-tailed deer lymphocytes. In relation to M. bovis diagnosis, vaccination of white-tailed deer with BCG can induce skin test responses that classify the animal as a tuberculosis reactor. In contrast, BCG vaccination will likely not interfere with tuberculosis testing by the IFN-gamma assay. C1 USDA ARS, Natl Anim Dis Ctr, Bacterial Dis Livestock Res Unit, Ames, IA 50010 USA.

On a daily basis, feed not consumed by inoculated deer after approximately 8 hr was offered to four naive deer maintained in a separate pen, where direct contact, aerosol transmission, or transmission through personnel were prevented. After 150 days, naive deer were euthanized and examined. All naive deer had lesions consistent with tuberculosis and M. bovis was isolated from various tissues. The most commonly affected tissues were lung, tracheobroncbial lymph nodes, and mediastinal lymph nodes. This study demonstrates the potential for indirect transmission of M. bovis through the sharing of feed. intentional or unintentional feeding of deer by wildlife, or agricultural interests in regions where M. bovis infection is endemic should be avoided because both direct and indirect transmission through sharing of feed are enhanced.

SO JOURNAL OF WILDLIFE MANAGEMENT LA English DT Article DE accipiter gentilis; backpack; kaibab plateau; northern goshawk; radiotelemetry; radiotransmitter; survival; tailmount ID RADIO TRANSMITTERS; MARKED ANIMALS; SPOTTED OWLS; BEHAVIOR; GROUSE; MOVEMENTS AB We used the Cormack-jolly-Seber model to estimate the effects of radiotransmitters on survival of breeding northern goshawks (Accipiter gentilis). We separately compared apparent annual survival of leg banded goshawks with (1) tailmount- and (2) backpack-style radio transmitters (hereafter tailmounts and backpacks) to apparent annual survival of breeding adults with legbands only. The best model without radiotransmitter effects, evaluated with Akaike's Information Criterion (AIC(c)), suggested no gender- or year-specific effects on survival. We then added radiotransmitter attachment type (tailmount or backpack) and mass of radiotransmitter as covariates to the base model to estimate the effect of radio transmitters. Tailmounts on males significantly reduced apparent annual survival from 0.75 (SE = 0.02, 95% CI: 0.71 to 0.78) without radiotransmitters to 0.29 (SE = 0.15, 95% CI: 0.09 to 0.63) with radiotransmitters. Backpacks had no significant effect on survival of adults (0.79, SE = 0.17, 95% CI: 0.33 to 0.97). The strikingly lower survival of goshawks with tailmounts was surprising because tailmounts weighed less (10 g, 1.5% body mass) than backpacks (16-23 g, max = 3.4% body mass) and likely were carried for shorter periods. Due to the small number of goshawks with tailmounts (n = 14) in this study, our results possibly were due to chance. We therefore recommend additional study of the effects of tailmounts on survival of breeding male northern goshawks. C1 US Forest Serv, Rocky Mt Forest & Range Expt Stn, Ft Collins, CO 80526 USA.

In our study, the first report of microsatellite variation among tule elk herds, we detected few significant genetic differences among herds. Furthermore, variation at 12 microsatellite loci was extremely limited within tule elk herds. We found large, significant differences between tule elk and both Rocky Mountain (C e. nelsoni) and Manitoban elk (C. e. manitobensis) at the same 12 microsatellite loci. Tule elk possessed less than or equal to 50% of the allelic diversity and heterozgosity found in the other subspecies. Tule elk were fixed at 5 loci at which the other subspecies possessed an average of 4.6 alleles. We observed very large pairwise F-st values and genetic distances between tule elk and both other subspecies, likely due to the very restricted variation in tule elk, rather than the presence of unique variation. Modeling of the genetic characteristics of tule elk indicated that management strategies involving transplants among all tule elk herds appear to be the most beneficial for the maintenance of nuclear variation in this subspecies. We also investigated impacts of small herd size and varying sex ratios on maintenance of microsatellite variation in tule elk.

Don) veneer was compressed using a roller press to mechanically remove water. The amount of water removed depended on the amount of compression applied. At 60% compression, 400kg/m(3) of water was removed. The process was not dependent on the size of the wood, the degree of compression, or the feed speed of the specimen. After compression, the remaining water contents were evenly distributed throughout the veneer regardless of the length of the specimen. The specimens did not completely recover to original thickness. High compression ratio and low temperature intensified the reduction of thickness. The bending strength after compression decreased in an inversely proportional manner with the thickness of the specimen and the compression degree.

Anthocyanin synthesis in some apple cultivars reportedly is also stimulated by exogenous ethylene, however, the role of ethylene action in regulation of anthocyanin synthesis in apple fruit is unclear. MJ enhances ethylene sensitivity in various plants, therefore, studies were conducted to evaluate the role of ethylene and MJ in stimulation of anthocyanin synthesis in immature 'Fuji' apple fruit. Following ethylene and MJ treatments, fruit were exposed simultaneously to UV-B and visible fight, then pigments were extracted and analyzed by reverse-phase high performance liquid chromatography. Treatment with MJ alone enhanced anthocyanin accumulation, including idaein, the major anthocyanin in apple fruit. Anthocyanin accumulation was further stimulated by treatment with MJ + ethylene. Treatment with the ethylene action inhibitor 1-MCP followed by MJ reduced red coloration over MJ alone. Treatment with ethylene or 1-MCP alone, or ethylene+1-MCP had little effect on anthocyanin accumulation. Chlorogenic acid synthesis was also enhanced by treatment with MJ or ethylene, however, treatment with 1-MCP alone or with MJ decreased chlorogenic acid content. MJ enhanced production of hyperin, the major quercetin glycoside in peel tissue, while ethylene and 1-MCP had no effect on quercetin glycoside content when applied alone or in any combination. beta-carotene synthesis was enhanced following MJ treatment, stimulated further by MJ plus ethylene, but was not enhanced by ethylene alone. The results indicate a synergistic response between ethylene and MJ for stimulation of anthocyanin synthesis. Treatments with ethylene alone or 1-MCP indicate a limited role for ethylene action in regulation of red color development by immature 'Fuji' apple fruit.

Field research demonstrated that this technology effectively provides a safe alternative to organophosphate and carbamate insecticides in a wide range of crops, including apple, pear, grape, blackberry, tomato, peach, and nectarine and the particle film product 'Surround Crop Protectant', is the first material to provide effective suppression of high heat damage and sunburn without the use of evaporative cooling. In organic agriculture, particle film technology represents the first broad utility material that provides effective insect control and high produce quality in organic fruits and vegetables. Its adoption by organic growers will further increase the growth of this expanding industry in the US and globally. Particle film technology, while still in its infancy, represents a broadly-based insect control system the impact of which could be similar to the development of the first synthetic insecticides but without the adverse effects on ecosystems. Additionally, particle film technology provides agriculture with the first sunburn and heat management tool that can manipulate ultraviolet, photosynthetically active radiation, and infrared radiation.

K. Koch] is unknown, but is closely linked to the size of the dormant season carbohydrate pool. Nut yields (over a period of up to 78 years) were evaluated, for 66 cultivars, in regards to alternate bearing intensity (1). Best-fit regression analysis indicates no association between I and fruit ripening date (FRD) or nut volume; although, there was moderate association with post-ripening foliation periods (PRFP) in that I tends to decrease as the length of the PRFP decreases. Multiple regression models indicated that FRD and nut volume were poor predictors of I, however PRFP possessed significant inverse predictive power. Late-season canopy health, as measured by percentage of leaflet retention, decreased as FRD approached early-season ripening. Late-season photoassimilation rate was higher on foliage of trees with late FRDs than those with mid- or early-season ripening dates. Sprays of either Alar or ProGibb to the canopy of either "On" or "Off" trees altered return bloom the following year. These data provide new insight into the complex nature of alternate bearing in pecan and are interpreted to indicate that alternate bearing in pecan is regulated by; a) gibberellins during the time of fruit development, and b) the size of the carbohydrate pool at about the time of bud break.

Good decision making requires analytical tools that vary both in scale and scope as they are applied to a wide spectrum of issues ranging from plant protection, soil and water conservation and climate change. To assess the degree of sustainability of a particular crop production system, there is a need to understand quantitatively the processes determining crop growth and how these are influenced by bio-physical factors and production practices. Field studies and long term experimentation is one way to get required information. They are often laborious, resource consuming and generally take longer to generate outputs for use in decision making. Crop models offer a less expensive and faster complimentary approach and can be useful to easily evaluate a number of alternative. strategies and risks in agricultural decision making. A model is a representation of a real crop production system, and usually describes the structure or function of that particular system. Simulation means using mathematical equations written in computer code to predict how a crop grows in a natural environment of soil, water and weather. In this paper we analyze the ways in which the crop simulation models are used as decision support tools in agriculture and natural resources management. An overview of the development of crop simulation models is presented. This follows a detailed discussion on successful application of such models in water management, irrigation planning, soil and water conservation, agro-forestry and alternate cropping systems. Role of crop simulation models in facilitating such strategic decision making process as climate change adaptations and agro-environmental policy analysis are also identified C1 USDA ARS, Beltsville Agr Res Ctr, Alternate Crops & Syst Lab, Beltsville, MD 20705 USA.

Available data indicated that Wildhorse Creek was one of the largest sediment yielding tributaries of the Umatilla River. Carbon, nitrogen and the nuclear bomb-derived radionuclide (137)Cs were used-as tracers to fingerprint sediment sources. Sediment was collected from the stream bottom and active floodplain and.-compared to samples from cultivated fields and channel banks. Samples were characterized on the basis of tracer concentrations and a simple mixing model was used to estimate the relative portion of bottom sediment derived from cultivated surface and channel banks. The results indicate that the amount of bottom sediment derived from cultivated surface sources was less than 26 per cent for the 1998 winter season, although this estimate has a high margin of error. Cesium-137 was also used to estimate surface erosion from three cultivated fields in the watershed. Annual estimates of erosion since 1963 from the three sampled fields were from 3 to 7(.)5 t ha(-1) yr(-1). For the 1998 season, it appears that most channel-bottom sediment was of subsurface origin with much of it likely coming from channel and gully banks indicating that significant reductions in sediment in Wildhorse Creek might be accomplished by the stabilization of eroding riparian areas and swales on the lower slopes of agricultural fields.

Observations of this land development adjacent to reserves or replacing dense forest call into question how the changes relate to forests or reserved lands. Using existing maps, this study first summarizes island-wide land-cover change between 1977-78 and 1991-92. Then, using binomial logit modeling, it seeks evidence that simple forest cover attributes, reserve locations, or existing land cover influence land development locations. Finally, this study quantifies land development, reserve protection and forest cover by ecological zone. Results indicate that 1) pasture is more likely to undergo land development than shrubland plus forest with low canopy density, 2) forest condition and conservation status appear unimportant in that development locations neither distinguish between classes of forest canopy development nor relate to forest patch size or reserve proximity, and 3) most land development occurs in the least-protected ecological zones. Outside the boundaries of strictly protected forest and other reserves, accessibility, proximity to existing urban areas, and perhaps desirable natural settings, serve to increase land development. Over the coming century, opportunities to address ecological zone gaps in the island's forest reserve system could be lost more rapidly in lowland ecological zones, which are relatively unprotected.

Humans influence fires both directly, by igniting and suppressing fires, and indirectly, by either altering vegetation, climate, or both. We used the LANDIS disturbance and succession model to compare the relative importance of a direct human influence (suppression of low intensity surface fires) with an indirect human influence (timber harvest ) on the long-term abundance and connectivity of high-risk fuel in a 2791 km(2) landscape characterized by a mixture of northern hardwood and boreal tree species in northern Wisconsin. High risk fuels were defined as a combination of sites recently disturbed by wind and sites containing conifer species/cohorts that might serve as "ladder fuel" to carry a surface fire into the canopy. Two levels of surface fire suppression (high/current and low) and three harvest alternatives (no harvest, hardwood emphasis, and pine emphasis) were compared in a 2 x 3 factorial design using 5 replicated simulations per treatment combination over a 250-year period. Multivariate analysis of variance indicated that the landscape pattern of high-risk fuel (proportion of landscape, mean patch size, nearest neighbor distance, and juxtaposition with non fuel sites) was significantly influenced by both surface fire suppression and by forest harvest (p > 0.0001). However, the two human influences also interacted with each other (p > 0.001), because fire suppression was less likely to influence fuel connectivity when harvest disturbance was simultaneously applied. Temporal patterns observed for each of seven conifer species indicated that disturbances by either fire or harvest encouraged the establishment of moderately shade-tolerant conifer species by disturbing the dominant shade tolerant competitor, sugar maple. Our results conflict with commonly reported relationships between fire suppression and fire risk observed within the interior west of the United States, and illustrate the importance of understanding key interactions between natural disturbance, human disturbance, and successional responses to these disturbance types that will eventually dictate future fire risk.

To test this perception, we (1) quantified changes and rates of change in vegetative composition and structure within the Washburn Ranger District in northern Wisconsin using Landsat images, (2) examined changes in landscape structure, (3) assessed changes within the area of road influence (ARI), and (4) investigated changes in landscape composition and structure within the context of forest management activities. Our landscape classifications included six dominant cover types: mixed hardwood (MH), jack pine (JP), red pine (RP), mixed hardwood/conifer (MHC), non-forested bare ground (NFBG), and regenerating forest or shrub (RFS). Increases in NFBG and RFS, by 196% and 28% respectively, reflect expansion of the pine-barrens. Windthrow in the mature hardwoods during the late 1970s and jack pine budworm outbreaks during the mid-1990s correlated with decreases in those classes over the corresponding intervals. A 69% decrease in mean patch size and a 60% increase in edge density reflect increased fragmentation. An inverse relationship existed between the compositional trends of forested (excluding JP) cover types and RFS and NFBG cover types. ARI covered 8% of the landscape affecting species composition within the MH, RFS, and NFBG. Results from this study are key in assessing the links between management activities and ecological consequences and thereby facilitate adaptive management.

Changes in fire regimes were documented by comparing historical fire rotations in different landscape ecosystems to those occurring between 1985 and 2000. Previously published data and a synthesis of the literature were used to identify six forest-replacement fire regime categories with fire rotations ranging from very short (< 100 years) to very long (> 1,000 years). We derived spatially-explicit estimates of the susceptibility of landscape ecosystems to fire disturbance using Landtype Association maps as initial units of investigation. Each Landtype Association polygon was assigned to a fire regime category based on associations of ecological factors known to influence fire regimes. Spatial statistics were used to interpolate fire points recorded by the General Land Office. Historical fire rotations were determined by calculating the area burned for each category of fire regime and dividing this area by fifteen (years) to estimate area burned per annum. Modern fire rotations were estimated using data on fire location and size obtained from federal and state agencies. Landtype Associations networked into fire regime categories exhibited differences in both historical and modern fire rotations. Historical rotations varied by 23-fold across all fire rotation categories, and modern forest fire rotations by 13-fold. Modern fire rotations were an order of magnitude longer than historical rotations. The magnitude of these changes has important implications for forest health and understanding of ecological processes in most of the fire rotation categories that we identified.

The study area is a mix of fire-prone and fire-resistant land types. The alternatives vary the spatial distribution of vegetation management activities to meet objectives primarily related to forest composition and recreation. The model simulates the spatial dynamics of differential reproduction, dispersal, and succession patterns using the vital attributes of species as they are influenced by the abiotic environment and disturbance. We simulated 50 replicates of each management alternative and recorded the presence of species age cohorts capable of sustaining canopy fire and the occurrence of fire over 250 years. We combined these maps of fuel and fire to map the probability of canopy fires across replicates for each alternative. Canopy fire probability varied considerably by land type. There was also a subtle, but significant effect of management alternative, and there was a significant interaction between land type and management alternative. The species associated with high-risk fuels (conifers) tend to be favored by management alternatives with more disturbances, whereas low disturbance levels favor low-risk northern hardwood systems dominated by sugar maple. The effect of management alternative on fire risk to individual human communities was not consistent across the landscape. Our results highlight the value of the LANDIS model for identifying specific locations where interacting factors of land type and management strategy increase fire risk.

One reason was that it brought spatial analysis and modeling to the forefront of ecological research. However, high expectations for landscape analysis to improve our understanding and prediction of ecological processes have largely been unfulfilled. We identified three kinds of critical issues: conceptual flaws in landscape pattern analysis, inherent limitations of landscape indices, and improper use of pattern indices. For example, many landscape analyses treat quantitative description of spatial pattern as an end itself and fail to explore relationships between pattern and process. Landscape indices and map data are sometimes used without testing their ecological relevance, which may not only confound interpretation of results, but also lead to meaningless results. In addition, correlation analysis with indices is impeded by the lack of data because of difficulties in large-scale experimentation and by complicated behavior of indices because of their varying responses to changes in scale and spatial pattern. These problems represent significant challenges to landscape pattern analysis, especially in terms of relating pattern to process. In this perspective paper, we examine the underlying problems of these challenges and offer some solutions. C1 US Forest Serv, USDA, Ctr Forested Wetlands Res, Charleston, SC 29414 USA.

One aspect of this quantification of particular importance to landscape ecologists is the classification of continuous variables to produce categorical variables such as land-cover type or elevation stratum. Although landscape ecologists are fully aware of the importance of spatial resolution in ecological investigations, the potential importance of the resolution of classifications has received little attention. Here we demonstrate the effects of using two different land-cover classifications to predict avian species richness and the occurrences of six individual species across the conterminous United States. We compared models built with a data set based on 14 coarsely resolved land-cover variables to models built with a data set based on 160 finely resolved land-cover variables. In general, comparable models built with the two data sets fit the data to similar degrees, but often produced strikingly different predictions in various parts of the country. By comparing the predictions made by pairs of models, we determined in which regions of the US predictions were most sensitive to differences in land-cover classification. In general, these sensitive areas were different for four of the individual species and for predictions of species richness, indicating that alternate classifications will have different effects in the analyses of different ecological phenomena and that these effects will likely vary geographically. Our results lead us to emphasize the importance of the resolution to which continuous variables are classified in the design of ecological studies.

These species, currently confined to the eastern half of the United States and not extending into Canada, are Diospyros virginiana (persimmon), Liquidambar styraciflua (sweetgum), Oxydendrum arboreum (sourwood), Pinus taeda (loblolly pine), and Quercus falcata var. falcata (southern red oak). DISTRIB uses a statistical approach to assess potential suitable habitat under equilibrium of 2 x CO2. SHIFT uses a cellular automata approach to estimate migration and is driven primarily by the abundance of the species near the boundary, forest density inside and outside of the boundary, and distance between cells. For each cell outside the current boundary, SHIFT creates an estimate of the probability that each unoccupied target cell will become colonized over 100 years. By evaluating the probability of colonization within the potential 'new' suitable habitat, we can estimate the proportion of new habitat that might be colonized within a century. This proportion is low (< 15%) for all five species, suggesting that there is a serious lag between the potential movement of suitable habitat and the potential for the species to migrate into the new habitat. However, humans could hasten the migration of certain species by physically moving the propagules, especially for certain rare species that are unable to move sufficiently through fragmented landscapes, or even more common species, e.g., beech, that have lost many of their animal dispersers.

To that end, we evaluated three statistical models: Regression Tree Analysis (RTA), Bagging Trees (BT) and Random Forest (RF) for their utility in predicting the distributions of four tree species under current and future climate. RTA's single tree was the easiest to interpret but is less accurate compared to BT and RF which use multiple regression trees with resampling and resampling-randomisation respectively. Future estimates of suitable habitat following climate change were also improved with BT and RF, with a slight edge to RF because it better smoothes the outputs in a logical gradient fashion. We recommend widespread use of these tools for GIS-based vegetation mapping. C1 USDA Forest Serv, Delaware, OH 43015 USA.

The multiangle data-processing technique that applies the layer-integrated form of the angle-dependent lidar equation, allows one to avoid the a priori selection of the extinction-to-backscatter ratio. However, the practical use of the technique is impeded by atmospheric horizontal heterogeneity and distortions in real lidar data, which worsen the inversion accuracy of the retrieved extinction-coefficient profiles; in addition, the multiangle solution is extremely sensitive even to minor systematic distortions in the inverted data. A combination of the one-directional and multiangle data-processing technique improves the measurement accuracy of the retrieved data. Here no guesses are required about the vertical profile of the extinction-to-backscatter ratio. The technique was developed and tested with experimental data using a two-wavelength scanning lidar at the Fire Sciences Laboratory in Missoula, MT, USA. The specifics, advantages, and restrictions of this combined technique are discussed and illustrated by both synthetic and experimental data.
