A modeling system has been designed to serve as a decision support system to help managers and resource specialists integrate the available knowledge of vegetation change and disturbance processes, and quantify concepts that are often difficult to interpret for specific landscapes. The system is named SIMPPLLE, an acronym taken from "SIMulating vegetation Patterns and Processes at Landscape scaLEs." SIMPPLLE can be used to help define and evaluate future conditions at landscape scales, to identify areas that are more prone to disturbances over a given time frame, to identify the options for influencing these disturbance processes, and to help design and evaluate different strategies for achieving desired future conditions. The emphasis in this article is to give an overview of the design of the system, the types of knowledge integrated, and the type of output produced. The initial validation work discussed indicates that the approach used for capturing and integrating process knowledge in SIMPPLLE does predict realistic results at landscape scales. SIMPPLLE provides managers a tool to integrate and interpret concepts of desired future conditions, range of variability, and the interaction between vegetation patterns and disturbance processes. SIMPPLLE provides a way to help evaluate proposed management scenarios within a future that includes stochastic processes.

We used a riparian LWD recruitment model (CWD, version 1.4) to test the validity of these assumptions. Both the number of contributing forest banks and predominant tree fall direction significantly influenced simulated riparian LWD delivery, but there was no apparent interaction between these factors. Pooled across all treatments, the average predicted 300-year cumulative LWD recruitment was 77.1 m(3)/100 m reach with both banks forested compared to 49.3 m(3)/100 m reach when only one side was timbered. Total recruitment within bank cover categories (one versus both forested) depended on the directionality of the falling stem. When only one bank was forested, the CWD model predicted the same riparian LWD recruitment for the random and CWD default tree fall patterns (similar to39 m(3)/100 m reach), the pattern biased toward the channel yielded twice this volume, a pattern quartering toward the channel produced 64% more LWD, and the pattern paralleling the channel contributed almost 30% less than random. With both banks forested, the random, default, and quartering simulations resulted in similar delivery (about 78 m(3)/100 m reach), the pattern biased toward the channel contributed almost 14% more LWD, and the parallel pattern yielded 26% less. Because CWD is similar in design and operation to other riparian LWD recruitment models, it follows that any simulation of wood delivery to streams should be checked for their consistency with local forest cover and tree failure patterns.

To address this continuing trend in habitat changes and begin restoring historical patterns of disturbance, the Clearwater Basin Elk Habitat Initiative (CEI) proposes relatively extensive management actions in the Clearwater basin of north-central Idaho. We attempted to evaluate potential effects of such management actions on selected wildlife species using extant data sets and suggest ways to improve such projects with respect to a multispecies and adaptive management approach. Although there is increased interest in ecosystem management over large areas, the increased scale of analysis and implementation require a substantial increase in the level of species information beyond what currently exists. We conclude that baseline information required for an effective multispecies land-management policy in the Clearwater basin does not exist for many terrestrial wildlife species. To implement a true multispecies or ecosystem approach, wildlife and land managers should cooperate to increase existing population data and modeling efforts for wildlife species in the basin and develop a sustainable monitoring program to evaluate habitat management changes and their influence on wildlife populations within the context of adaptive management theory. Management actions to restore disturbance patterns should attempt spatial and temporal scales that are biologically relevant to the population ecology of species being affected.

We compared relative abundance, habitat use, and area of use of red squirrels (Tamiasciurus hudsonicus) and northern flying squirrels (Glaucomys sabrinus) before and after two different treatments designed to remove a range of dwarf mistletoe-caused witches' brooms in northeastern Oregon in 1998-2002. Dwarf mistletoe sanitation treatments included: (1) an island treatment, with retention of up to 0.5 ha groups of trees containing witches' brooms in evenly distributed uncut islands, and all harvest activity confined to thinning from below outside these islands to eliminate trees containing witches' brooms; and (2) a total removal treatment, which consisted of removing all trees that contained a witches' broom estimated to be >25 cm in diameter. Before treatment, over half of the red squirrels and northern flying squirrels in the treatment area occupied summer rest sites in witches' brooms on large Douglas-fir (Pseudotsuga menziesii). Live trapping indicated a pretreatment abundance of 1.0 per 100 trap/nights for red squirrels and 0.4 per 100 trap/nights for northern flying squirrels, and a posttreatment abundance of 2.1 per 100 trap/hights for red squirrels and 0.2 per 100 trap/nights for northern flying squirrels. Type of rest site and amount of red squirrel reuse did not change after the island treatment, although the number of red squirrels located in rest sites increased with the island treatment. Most of the red squirrel locations occurred within the islands. Area of use by red squirrels did not change with island treatment. Type of rest site used by red squirrels and northern flying squirrels shifted after the total removal treatment from mostly witches' brooms to predominantly tree cavities. Area of use by red squirrels increased from 1.8 to 7.6 ha after the total removal treatment. Results suggest that retention of trees containing witches' brooms in small groups or islands offers an opportunity to retain rest site habitat, although northern flying abundance declined with both treatments.

Specific objectives were to measure the richness and density of functional groups within the grassland community, measure the biomass of each functional group, and calculate diversity indices for each functional group. We hypothesized that diversity would be greater than previous descriptions for the Festuca idahoensis/Agropyron spicatum habitat type because our multiple-season method would recognize seasonal and environmental variations in community composition. Of the species present, we hypothesized that forb functional groups account for the majority of richness and biomass of this grassland plant community Species richness and density were measured during spring, summer, and fall of 2000, and biomass was collected during spring, summer, and fall of 2001. Species richness was measured by counting all species present on 4-m(2) plots. We measured forb density per 4-m(2) plot and determined grass density by counting tillers per species within a 0.2x0.5-m frame. Diversity indices were calculated for each functional group. Biomass by functional group was clipped front three 0.2x0.5-m frames per 4-m(2) plot. Data support the hypothesis that multiple-season sampling recognizes greater species diversity at one location because both sites were more diverse plant communities than previously described for this habitat type. We documented 14 graminoids and 69 forbs front just 2 sites. Total diversity of a 4-m(2) plot averaged 42 species, consisting of 5 grasses, 12 deep-rooted forbs, and 25 shallow-rooted forbs. Our data also support the hypothesis that forb functional groups represent the majority of the richness and biomass of the grassland community. Forbs account for 83% of species richness in this research. In addition, forbs represent a greater proportion of plant biomass than grasses on our sites. Functional group diversity and forb diversity should be a larger consideration in Festuca idahoensis/Agropyron spicatum grassland management decisions. We recommend that land managers recognize forb species and forb functional group diversity in grassland classifications. Maintaining diversity should be a primary objective of land managers because increased diversity has been found to increase community stability and productivity and decrease the risk of invasion by undesired species. To encourage land managers to put more resources into monitoring diversity, a simple and repeatable sampling procedure applicable to both community and landscape scales needs to be developed.

Recycling CCA-treated wood from the decks could be a feasible alternative, but there is a lack of knowledge regarding the physical properties of the material. This research analyzed the chemical and mechanical properties of spent CCA-treated wood from residential decks to evaluate the material for reuse in other applications. Several of the joists and the decking of removed decks were found to be below the originally stated retention level. The joists had higher retention levels, and length of service was not a factor in level of chemical retention in the decking or joists. The spent decking had similar stiffness properties, but the bending strength was lower than recently treated material. As with the chemical properties, the mechanical properties were not affected by the amount of time the deck was in service. Overall, it was found that the preservative retention properties were lower than expected, the stiffness was equal to, and the strength was lower than, recently CCA-treated wood. This does not indicate that the material is unusable, but aids in determining suitable applications where recycled CCA-treated wood can be used. C1 PalletOne, Bartow, FL 33830 USA.

These procedures do not incorporate estimates of the modulus of elasticity (MOE) of logs. It is questionable whether the visual grading procedures currently used for logs adequately assess the potential quality of structural products manufactured from them, especially those for which MOE is of primary concern. The purpose of this study was to investigate the use of stress wave nondestructive evaluation techniques to sort red maple logs for the potential quality of lumber obtained from them. Ninety-five red maple logs were nondestructively evaluated using longitudinal stress wave techniques and sorted into four stress wave grades. The logs were then sawn into cants and lumber. The same procedure was used to obtain stress wave times in the cants and lumber. The lumber specimens were then dried and graded using a transverse vibration technique. The results of this study showed that good relationships existed between stress wave times measured in logs, cants, and the lumber produced from the logs. It was found that log stress wave grades have positive relationships with the lumber grades. Logs with high stress wave grades produced high-grade lumber. These findings indicate that the longitudinal stress wave technique has potential in sorting logs and cants for the production of high MOE products.

DU-145 and Tsu-Pr1 cells were included for comparative purposes. uPAR expression increases with metastatic passage in these cell lines and accompanies increased growth and motility responses in the presence of uPA. Growth factors TGFbeta1 and IGF-1 induce uPAR in all three prostate cancer lines; however, PC-3M and PC-3MM2 cells also respond to bFGF. Of the cell lines tested, PC-3MM2 most uniformly respond to added TGFbeta1, IGF-1 and bFGF. These results show that in two progressive derivatives from repeated metastasis of PC-3 cells, constitutive and growth factor-induced uPAR expression is enhanced. This increased uPAR facilitates the properties of growth and motility. C1 Louisiana State Univ, Sch Vet Med Comparat Biomed Sci, Baton Rouge, LA 70809 USA.

Virgin female (n = 120) and male (n = 40) rats of an outbred laboratory population were used for the experiments. Groups of rats (I male and 3 females) were housed in standard cages in close proximity to the predator. Litter size, sex ratio. number of alive pups, number of placental scars and corpora lutea were counted; pre- and post-implantation losses were calculated for each female. The reproductive success of females calculated as a number of alive pups per female was much higher in both control groups (20 and 80 m) than in both test groups (2 and 2 m). Equal numbers of corpora lutea in all groups but different numbers of placental scars between the control and test groups indicated a higher pre-implantation loss in the experimental groups. The post-implantation loss was also higher in both test groups. The total loss (calculated as a difference between the number of corpora lutea and living, pups) was twice as high as in experimental groups. Reproductive success of rats is related to the concentration/intensity was of predator's stimuli: when the concentration/intensity was higher, the number of live pups was less, and the total loss was higher.

Two study sites were selected: a semi-arid area located in northern Chihuahuan desert, USA, and a Savannah landscape located in central Africa. Atmospheric corrections were performed using the MODTRAN 4 atmospheric radiative transfer code along with atmospheric profiles generated by the National Center for Environmental Predictions (NCEP). Atmospheric radiative properties were derived from MODTRAN 4 calculations according to the sensor swaths, which yielded different strategies from one sensor to the other. The MODIS estimates were then computed using a designed Temperature-Independent Spectral Indices of Emissivity (TISIE) method. The ASTER estimates were derived using the Temperature Emissivity Separation (TES) algorithm. The MODIS and ASTER radiometric temperature retrievals were in good agreement when the atmospheric corrections were similar, with differences lower than 0.9 K. The emissivity estimates were compared for MODIS/ASTER matching bands at 8.5 and 11 mum. It was shown that the retrievals agreed well, with RMSD ranging from 0.005 to 0.015, and biases ranging from -0.01 to 0.005. At 8.5 mum, the ranges of emissivities from both sensors were very similar. At 11 mum, however, the ranges of MODIS values were broader than those of the ASTER estimates. The larger MODIS values were ascribed to the gray body problem of the TES algorithm, whereas the lower MODIS values were not consistent with field references. Finally, we assessed the combined effects of spatial variability and sensor resolution. It was shown that for the study areas we considered, these effects were not critical. (C) 2004 Elsevier Inc.

Although many studies have been conducted to estimate moisture in bare soil fields with Synthetic Aperture Radar (SAR) imagery, little success has been achieved in vegetated areas. The purpose of this study is to extract soil moisture in sparsely to moderately vegetated rangeland surfaces with ERS-2/TM synergy. We developed an approach to first reduce the surface roughness effect by using the temporal differential backscatter coefficient (Deltasigma(wet-dry)(0)). Then an optical/microwave synergistic model was built to simulate the relationship among soil moisture, Normalized Difference Vegetation Index (NDVI) and Deltasigma(wet-dry)(0). With NDVI calculated from TM imagery in wet seasons and Deltasigma(wet-dry)(0) from ERS-2 imagery in wet and dry seasons, we derived the soil moisture maps over desert grass and shrub areas in wet seasons. The results showed that in the semiarid rangeland, radar backscatter was positively correlated to NDVI when soil was dry (m(v) < 10%), and negatively correlated to NDVI when soil moisture was higher (m(v)>10%). The approach developed in this study is valid for sparse to moderate vegetated areas. When the vegetation density is higher (NDVI>0.45), the SAR backscatter is mainly from vegetation layer and therefore the soil moisture estimation is not possible in this study. (C) 2004 Elsevier Inc.

This fatty acid contains structural features that are not typically found in plant fatty acids, including a C-9 hydroxyl group, Delta(10),Delta(12)-conjugated double bonds, and trans-Delta(12) unsaturation. Expressed sequence tag analysis was conducted to determine the biosynthetic origin of dimorphecolic acid. cDNAs for two divergent forms of Delta(12)-oleic acid desaturase, designated DsFAD2-1 and Ds-FAD2-2, were identified among expressed sequence tags generated from developing Dimorphotheca sinuata seeds. Expression of DsFAD2-1 in Saccharomyces cerevisiae and soybean somatic embryos resulted in the accumulation of the trans-Delta(12) isomer of linoleic acid (18: 2Delta(9cis,12trans)) rather than the more typical cis-Delta(12) isomer. When co-expressed with DsFAD2-1 in soybean embryos or yeast, DsFAD2-2 converted 18:2Delta(9cis,12trans) into dimorphecolic acid. When DsFAD2-2 was expressed alone in soybean embryos or together with a typical cis-Delta(12)-oleic acid desaturase in yeast, trace amounts of the cis-Delta(12) isomer of dimorphecolic acid (9-OH-18:2Delta(9cis,12cis)) were formed from DsFAD2-2 activity with cis-Delta(12)-linoleic acid. These results indicate that DsFAD2-2 catalyzes the conversion of the Delta(9) double bond of linoleic acid into a C-9 hydroxyl group and Delta(10trans) double bond and displays a substrate preference for the trans-Delta(12), rather than the cis-Delta(12), isomer of linoleic acid. Overall these data are consistent with a biosynthetic pathway of dimorphecolic acid involving the concerted activities of DsFAD2-1 and DsFAD2-2. The evolution of two divergent Delta(12)-oleic acid desaturases for the biosynthesis of an unusual fatty acid is unprecedented in plants.

Three experiments were completed. In the first experiment, three groups of pigs (10 pigs/group) were inoculated intranasally with either B. bronchiseptica, H. parasuis, or with B. bronchiseptica followed by H. parasuis I week later. A fourth group of 10 pigs served as a non-infected control group. The second experiment was like the first, except that there were only five pigs per experimental group. The third experiment consisted of only two groups (10 pigs/group), one of which was inoculated intranasally with H. parasuis, whereas the other was inoculated with B. bronchiseptica followed by H. parasuis I week later. Pigs were necropsied 1-2 weeks after inoculation with H. parasuis. Mean nasal colonization by H. parasuis was significantly higher in the coinfected groups compared to the groups infected with H. parasuis alone. Pneumonia was present in 9/25 pigs coinfected with B. bronchiseptica and H. parasuis, 5/25 pigs infected with H. parasuis alone, 1115 pigs infected with B. bronchiseptica alone, and in none of the pigs in the non-inoculated groups. Thus, B. bronchiseptica increased colonization of the upper respiratory tract with H. parasuis. Published by Elsevier B.V.

We conducted a longitudinal study of feeding behavior to determine if pregnancy-related changes in food selection and intake occurred in goats. Goats eat modest amounts of toxic plants, some of which contain teratogenic or abortifacient compounds, but it is not known if pregnant and non-pregnant goats differ in food selection. The embryo is susceptible to toxins during all stages of pregnancy, but especially so during organogenesis early in pregnancy. Thus, we hypothesized that food selection and intake by pregnant versus non-pregnant goats may differ during various stages of pregnancy. We examined the following predictions that stem from this hypothesis: relative to non-pregnant goats, pregnant goats may alter selection of familiar foods that contain toxins, and of familiar and unfamiliar foods that do not contain toxins. We fed 14 plants with known or probable teratogenic properties during two pregnancies. We also offered beet pulp containing 0.5% LiCl during one pregnancy to test for increased sensitivity to toxins. In addition, we offered novel foods several times during one pregnancy to test for increased food neophobia. or neophyllia. Finally, we measured intake of the basal ration by pregnant and non-pregnant goats daily throughout both pregnancies. Both pregnant and non-pregnant goats ate modest amounts of the plants with toxins and of beet pulp with LiCl. Both groups limited intake of novel foods and beet pulp with LiCl to the same degree. Finally, pregnant and non-pregnant goats did not differ in intake (per kg MBW) of the basal ration-dry matter, energy, or protein-in either pregnancy. Thus, the data do not support the notion that goats experienced pregnancy-related changes in food selection or intake. (C) 2003 Elsevier B.V. All rights reserved.

The major modifications focused on simulations of anaerobic biogeochemistry and rice growth as well as parameterization of paddy rice management. The new model was tested for its sensitivities to management alternatives and variations in natural conditions including weather and soil properties. The test results indicated that ( 1) varying management practices could substantially affect carbon dioxide (CO2), methane (CH4), or nitrous oxide (N2O) emissions from rice paddies; (2) soil properties affected the impacts of management alternatives on GHG emissions; and ( 3) the most sensitive management practices or soil factors varied for different GHGs. For estimating GHG emissions under certain management conditions at regional scale, the spatial heterogeneity of soil properties (e.g., texture, SOC content, pH) are the major source of uncertainty. An approach, the most sensitive factor (MSF) method, was developed for DNDC to bring the uncertainty under control. According to the approach, DNDC was run twice for each grid cell with the maximum and minimum values of the most sensitive soil factors commonly observed in the grid cell. The simulated two fluxes formed a range, which was wide enough to include the "real'' flux from the grid cell with a high probability. This approach was verified against a traditional statistical approach, the Monte Carlo analysis, for three selected counties or provinces in China, Thailand, and United States. Comparison between the results from the two methods indicated that 61-99% of the Monte Carlo-produced GHG fluxes were located within the MSA-produced flux ranges. The result implies that the MSF method is feasible and reliable to quantify the uncertainties produced in the upscaling processes. Equipped with the MSF method, DNDC modeled emissions of CO2, CH4, and N2O from all of the rice paddies in China with two different water management practices, i.e., continuous flooding and midseason drainage, which were the dominant practices before 1980 and in 2000, respectively. The modeled results indicated that total CH4 flux from the simulated 30 million ha of Chinese rice fields ranged from 6.4 to 12.0 Tg CH4-C per year under the continuous flooding conditions. With the midseason drainage scenario, the national CH4 flux from rice agriculture reduced to 1.7 - 7.9 Tg CH4-C. It implied that the water management change in China reduced CH4 fluxes by 4.2 - 4.7 Tg CH4-C per year. Shifting the water management from continuous flooding to midseason drainage increased N2O fluxes by 0.13 - 0.20 Tg N2O-N/yr, although CO2 fluxes were only slightly altered. Since N2O possesses a radiative forcing more than 10 times higher than CH4, the increase in N2O offset about 65% of the benefit gained by the decrease in CH4 emissions.

In the present study we have employed three different life cycle stages of the nematode Ostertagia ostertagi to determine if products of this economically important parasite inhibit in vitro proliferation of Con A-stimulated cells from uninfected animals. We have demonstrated an inhibitory effect upon the growth of Con A-stimulated lymphocytes after addition of fourth stage larval (L4) soluble extract (L4SE) to the cultures. In contrast, extracts from the third stage larvae (L3) had little or no inhibitory activity. The suppressive products were also shown to be secreted by the late L4. The suppressive activity is reversible if the L4 products are removed from culture. There is no immediate effect on proliferating cells and the L4SE must be in culture for 24-48 h before suppression is observable. The L4SE caused slight but not statistically significant decreases in the percentage of T cells and increases in B cell percentages in cultures when compared with cultures stimulated with Con A alone. No changes were seen in percentage of cells positive for markers for CD4, CD8, gammadelta T cells, or monocytes/macrophages as a consequence of the addition of L4SE. In contrast, there was a strong and significant reduction in the expression of the IL-2 receptors in cells cultured in the presence of the worm extract. There was no evidence of either necrosis or apoptosis resulting from the presence of L4 products in culture. The expression of messenger RNA for interleukin-2, -4, -13, tumor necrosis factor-alpha (TNF-alpha), and gamma-interferon (gamma-IFN) was decreased when L4SE was included in cultures of Con A-stimulated cells compared to cultures stimulated with Con A only. In contrast, messenger RNA expression of transforming growth factor-beta (TGF-beta) and interleukin-10 (IL-10) was increased in cells growing in the presence of L4 products. The potential role of these cytokines during ostertagiosis is discussed. (C) 2004 Elsevier B.V. All rights reserved.

The revised status of both Schinia albafascia Smith and Schinia brunnea Barnes and McDunnough are based on differences in wing maculation and male and female genitalic structures. The revised synonymy of Schinia megarena Smith with Schinia tertia (Grote) is discussed. Male and female genitalia are described and illustrated for the first time for all species.

Near-infrared (NIR) spectroscopy has been used to predict total utilizable energy in cereal foods for nutrition labeling purposes, and in the current study, was investigated as a method for evaluation of the amount of energy derived from fat. Using NIR reflectance spectra (1104-2494 nm) of ground cereal samples and reference values obtained by calorimetry and by calculation, modified PLS regression models were developed for the prediction of percent energy from fat and energy from fat/g. The models were able to predict the percent of utilizable energy derived from fat with SECV and R-2 of 1.86-1.89% of kcal (n = 51, range 0-43.0) and 0.98, respectively, and SEP and r(2) of 1.74% of kcal (n = 55, range 0-38.0) and 0.98, respectively, when used to predict independent validation samples. Results indicate that NIR spectroscopy provides useful methods for predicting the energy derived from fat in food products.

Humans are accelerating the rate of species turnover by moving species around the planet and dramatically changing environmental conditions. Our focus is on new forests in Puerto Rico that emerge naturally on abandoned lands previously converted to agriculture and degraded. These forest stands have combinations of species that are new to the island's landscapes. New forests exhibit high species dominance during forest establishment, which includes dominance by alien tree species. These alien tree species establish and maintain forest cover, which may facilitate regeneration of native tree species. Landscape analysis and literature review revealed that these emerging stands are highly fragmented (60% were <1 ha in 1991), function as refugia for native organisms, and at 60-80 years old have similar species richness and structural features as native stands of similar age. However, the island's new forests exhibit important differences from mature native forests on unconverted forestlands. New forests have fewer endemic species and fewer large trees (greater than or equal to55 cm dbh) than mature, native forests; they have higher soil bulk density and lower soil carbon and litter stocks; and they accumulate aboveground biomass, basal area, and soil carbon more slowly than native forests of similar age. We suggest that new forests will become increasingly prevalent in the biosphere in response to novel environmental conditions introduced to the planet by humans. Published by Elsevier B.V.

We studied chestnut-sided warblers (Dendroica pensylvanica), which are an early-successional shrubland bird, nesting in 29 patches of regenerating (4-5 years old) northern hardwoods forest 0.15-0.69 ha in area to determine whether the ecology of this species is affected by patch size or shape. Chestnut-sided warbler density decreased with patch size, however nests were initiated earlier in larger patches. There were no relationships between patch area and number of young fledged per territory or nest predation rates. Similarly, there were no relationships between patch shape (defined as the ratio of the patch perimeter to the perimeter of a circle of the same area) and territory density, date of initiation of first nests, number of young fledged per territory, or nest predation rates. These results contrast with the results of studies of area sensitivity of mature forest and grassland birds, in which bird density is negatively related to patch area. However, later nest initiation in smaller patches suggests that smaller patches are lower quality habitat, which is consistent with the negative relationships between patch area and habitat quality reported in studies of birds nesting in patches of mature forest.

Our objectives in this study were to evaluate the watershed scale effects of understory burning on total aboveground biomass, and the carbon and nitrogen pools in coarse woody debris (CWD), forest floor and soils. We also evaluated the effects of burning on three key biogeochemical fluxes; litterfall, soil CO(2) flux and soil net nitrogen mineralization. We found burning significantly reduced understory biomass as well as the carbon and nitrogen pools in CWD, small wood and litter. There was no significant loss of carbon and nitrogen from the fermentation, humus and soil layer probably as the result of low fire intensity. Burning resulted in a total net loss of 55 kg ha(-1) nitrogen from the wood and litter layers, which should be easily replaced by future atmospheric deposition. We found a small reduction in soil CO(2) flux immediately following the burn but litterfall and net nitrogen mineralization were not significantly different from controls throughout the growing season following the burn. Overall, the effects of burning on the ecosystem processes we measured were small, suggesting that prescribed burning may be an effective management tool for restoring oak-pine ecosystems in the southern Appalachians.

Although the general pattern of ecosystem response to climate forcing was similar in both years, latent heat and CO2 fluxes showed significant variations between and within the growing seasons. The main differences between the two years were a consequence of an extended drought that lasted from October 2001 to July 2002. Most of the within season variability was attributable to the timing and magnitude of mid-summer precipitation associated with the North American Monsoon. Following new tree leaf production and prior to the monsoon onset, there was little precipitation; daytime air temperatures were high and relative humidity low. Evapotranspiration and water level data indicated that the mesquite trees always had ready access to groundwater, though they were likely supplementing this with vadose zone soil water when abundant. Nonetheless, decreases in afternoon transpiration and CO2 uptake suggest stomatal regulation of leaf gas exchange, possibly in response to the high vapor pressure deficit. Because near-surface soil moisture was limited prior to the summer rains, ecosystem respiration was low and there was little evapotranspiration from understory plants and soil. With the arrival of the monsoon rains, understory vegetation activity and, consequently, total ecosystem evapotranspiration increased. Total ecosystem photosynthesis also increased, but the net uptake of carbon decreased, due to enhanced respiration from the abundant carbon sources, stimulated by the precipitation and warm temperatures. The nighttime measurements of CO2 fluxes, although of questionable accuracy, imply the ecosystem was a net sink of CO2 for most of the two growing seasons. (C) 2003 Elsevier B.V. All rights reserved.

Both genetic changes provided, within a uniform genetic background, a test of the "source-sink" hypothesis that down-regulation of photosynthesis in elevated carbon dioxide is a result of inability to form sufficient "sinks" for the additional photosynthate. Plants were grown under ambient and elevated [CO2] (550 mumol mol(-1)) in the field, using free air gas concentration enrichment (FACE). Mutation of the determinate cultivar, Elf, to an indeterminate form did not result in increased responsiveness to elevated [CO2]. This may reflect a large sink capacity in the selection of determinate cultivars. In elevated [CO2] only the determinate isoline of the indeterminate cultivar (Williams-dtl) and the non-nodulating genotype showed down-regulation of photosynthesis. This resulted from decreases in apparent in vivo Rubisco activity (V-c.max) and maximum rate of electron transport Increase in total non-structural carbohydrate (TNC) content, which is often correlated with down-regulation of photosynthesis, in Williams-dtl was 80% greater in elevated [CO2] than in ambient [CO2] controls, compared to 40% in the indeterminate line. The results from mutations of the Williams line are consistent with the hypothesis that genetic capacity for the utilization of photosynthate is critical to the ability of plants to sustain increased photosynthesis when grown at elevated [CO2] (C) 2003 Elsevier B.V.

They are characterized by slow, meristematic growth and very thick, darkly pigmented cell walls. The dark pigment, generally thought to be melanin, is consistently present in their cell walls when they grow under saline and non-saline conditions. We used the inhibitor tricyclazole to test the fungi in this study for the presence of 1,8-dihydroxynaphthalene (DHN)-melanin biosynthesis, since fungal melanins reportedly are derived either from DHN, tyrosine via 3,4-dihydroxyphenylalanine, gamma-glutaminyl-3,4-dihydroxybenzene, or catechol. Tricyclazole-treated cultures of the fungi were reddish-brown in color and contained typical intermediates of the DHN-melanin pathway, as demonstrated by high-performance liquid chromatography. This investigation showed that the three fungi synthesized DHN-melanin under saline and non-saline growth conditions. (C) 2004 Federation of European Microbiological Societies.

We show that growth rings in long-lived geoduck clams (Panopea abrupta) can provide high quality, annually resolved records of sea-surface temperature (SST). We used shell samples from the Strait of Juan de Fuca, in Washington State, to extend the coastal SST record back to 1877. The spatial correlation pattern between the growth index and gridded SSTs bears a strong resemblance to the leading pattern of interdecadal global SST variations and underscores the remarkable long-distance coherence evident among coastal SST records in the northeast Pacific. Our results also indicate that the 1990s was the warmest decade in this region since at least the 1850s. C1 WDFW Point Whitney Shellfish Lab, Brinnon, WA USA.

Annual mean, flux-weighted delta(13)C values of net ecosystem CO2 exchange (NEE) were estimated for four contrasting ecosystems (three forests and one grassland) by analyzing daytime flask measurements collected at the top of canopies. Combining delta(13)C values associated with respiratory and net (respiration minus photosynthesis) fluxes, we demonstrate a method for estimating whole-canopy photosynthetic discrimination against C-13 (Delta(A)) in terrestrial ecosystems directly from field measurements. This experimental approach offers the possibility of examining interannual variability in Delta(A) from ecosystem delta(13)C measurements. Our estimated delta(13)C values associated with photosynthetic fluxes are in agreement with those measured from foliar organic matter for C-3 forests, and are within the range bounded by C-3 and C-4 grasses in a tallgrass prairie. The delta(13)C associated with NEE fluxes at our C-3 forest sites ranges between -27.1 +/- 2.7 and -28.3 +/- 2.5parts per thousand, and is -22.6 +/- 4.0parts per thousand at the prairie site. These estimates differ from a previous study, particularly for C-3 ecosystems at comparable latitudes. Sensitivity analyses indicate that our estimates of delta(13)C values of net CO2 fluxes are robust with respect to measurement errors, but can vary depending on the selection of background atmospheric values. Other factors (e.g., drought and sampling footprint) that might have influenced our delta(13)C measurements and calculations of Delta(A) are also discussed. Our measurement-based analyses are particularly useful when both latitudinal and longitudinal variations in Delta(A) are to be considered in the global inversion modeling studies.

Arguments in favor of hierarchical modeling are made, especially for considering a complex environmental issue like widespread eastern hemlock regeneration failure. We present the philosophy and basic framework for the NORTHern Woodland Dynamics Simulator (NORTHWDS) Integrated Hierarchical Model System (NIHMS). NIHMS has an individual tree component (the NORTHWDS Individual Response Model (NIRM)), a mesoscale stand simulator (NORTHWDS), and a landscape model (NORTHWDS Landscape Model (NLM, presented in another paper)). NIRM predicts the behavior of a tree given the physical and biotic environment that constrains its performance, using process-response functions at a scale larger than the individual plant. The NORTHWDS model integrates both the structure of the individual tree model (including tree growth and mortality functions) with a series of ecosystem processes (e.g. competition, site biogeochemistry, small-scale disturbance, deer browsing) and even larger scale events (e.g. catastrophic windthrow) to predict long-term stand dynamics on a 5-year simulation cycle. The boundaries in time and space between the NIRM, NORTHWDS, and NLM models are not discrete, but overlap due to the multiscale expression of ecological and physiological processes. For example, the NORTHWDS model represents both the intersection between the NIRM and NLM models with additional unique mesoscale processes (e.g. intertree competition). At the highest level of NIHMS, NLM provides the environmental context for NORTHWDS, with all levels operating in an internally consistent and parsimonious manner. Three case study scenarios are used to illustrate some of the potential applications of NIRM. Scenario 1: simulation of northern red oak survivorship, crown dynamics, diameter increment, and cumulative propagule production under different local stand densities; Scenario 2: the response of white ash along an available nitrogen gradient with respect to mortality, crown surface area, diameter growth, tree biomass, and propagule production; and Scenario 3: the survivorship and total propagule production of black spruce along a soil moisture gradient. Under Scenario 1, crown size decreased appreciably as local stand density increased from open-grown (<1 m(2)/ha) to closed canopy conditions (15-30 m(2)/ha), triggering reduced annual increment, lower established propagule production, and increased small tree mortality. Similarly, nitrogen (for white ash) and moisture (for black spruce) gradients significantly affected crown size and growth potential, with many of the same consequences as noted for increased competition in northern red oak. These predictions were consistent with ecological expectations for all scenarios except the black spruce moisture gradient response, which arose because of scale-related issues and the complexity of gradients. To evaluate NORTHWDS model behavior, a 36 ha synthetic stand resembling a hardwood-dominated forest from northern Wisconsin was simulated for 300 years using four windthrow disturbance scenarios (no windthrow, acute windthrow only, chronic windthrow only, and both types of windthrow). Acute (particularly severe but locally discrete and infrequent events) windthrow patterns were designed to generate many small, low intensity events, while chronic windthrow (pervasive yet low intensity cyclic loss of trees) losses depended on species, stature, rooting depth, and tree exposure. These scenarios were compared by examining differences in structural (i.e. biomass, tree richness) and compositional attributes for a number of key species. NORTHWDS predicted the maturation of a pole-sized aspen stand and its eventual conversion to a predominantly sugar maple forest. Quantitatively, aboveground biomass levels comparable to field data were forecast (up to 250-300 Mg/ha, depending on the scenario). The predicted dominance of sugar maple was also consistent with other regional studies, and can be attributed to its shade and browsing tolerance. (C) 2003 Elsevier B.V. All rights reserved.

Poly (vinyl alcohol) (PVA) was used as the synthetic polymer of choice by virtue of its capability to be processed from water solution or suspension as well as from the melt by blow extrusion and injection molding. Starch and gelatin were taken as the polymeric materials from renewable resources. The fillers were all of natural origin, as waste from food and agro-industry consisted of sugar cane bagasse (SCB), wheat flour (WF), orange peels (OR), apple peels (AP), corn fibres (CF), saw dust (SD) and wheat straw (WS). All the natural or hybrid formulations were intended to be utilized for the production of: a) Environmentally degradable mulching films (hydro biomulching) displaying, in some cases, self-fertilizing characteristics by in situ spraying of water solutions or suspensions; b) Laminates and containers to be used in agriculture and food packaging by compression and injection molding followed by baking. Some typical prototype items have been prepared and characterized in relation to their morphological and mechanical properties and tested with different methodology for their propensity to environmental degradation and biodegradation as ultimate stage of theirservice life. A relationship between chemical composition and mechanical properties and propensity to biodegradation has been discussed in a few representative cases.

Current methods of measuring residue cover are inadequate for characterizing the spatial variability of residue cover over large fields. The objectives of this research were to determine the spectral reflectance of crop residues and soils and to assess the limits of discrimination that can be expected in mixed scenes. Spectral reflectances of dry and wet crop residues plus three diverse soils were measured over the 400-2400 nm wavelength region. Reflectance values for scenes with varying proportions of crop residues and soils were simulated. Additional spectra of scenes with mixtures of crop residues, green vegetation, and soil were also acquired in corn, soybean, and wheat fields with different tillage treatments. The spectra of dry crop residues displayed a broad absorption feature near 2100 nm, associated with cellulose-lignin, that was absent in spectra of soils. Crop residue cover was linearly related (r(2) = 0.89) to the Cellulose Absorption Index (CAI), which was defined as the relative depth of this absorption feature. Green vegetation cover in the scene attenuated CAI, but was linearly related to the Normalized Difference Vegetation Index (NDVI, r(2) = 0.93). A novel method is proposed to assess soil tillage intensity classes using CAI and NDVI. Regional surveys of soil conservation practices that affect soil carbon dynamics may be feasible using advanced multispectral or hyperspectral imaging systems. (C) 2004 Elsevier Inc.

Groups of embryonic day (ED) 17 chicken embryos and 1-day-old chicks were compared for tissue sites of viral persistence of MDV and herpesvirus of turkeys (HVT) in lungs, thymuses, bursae of Fabricius and spleens. MDV DNA was detectable in the lungs and thymuses of embryos at 3 days post-inoculation (DPI) by in situ hybridization, while HVT DNA was only present in embryonic lungs. The target cells in lungs and thymuses appeared non-lymphoid and lymphoid, respectively. By 5 days post-inoculation, both viruses were detectable in all organs examined and persisted after hatch. Although MDV DNA was present in the embryo, there was little evidence of viral replication. These findings demonstrate the differences in pathogenesis of embryonic infection with MDV and HVT and provide evidence that the chicken embryo is susceptible to infection with a virulent avian herpesvirus.

SO FIELD CROPS RESEARCH LA English DT Article DE soil quality; organic farming; n mineralization; tomato; maize ID CALIFORNIA SACRAMENTO VALLEY; MICROBIAL COMMUNITIES; MANAGEMENT; AGRICULTURE; INDICATORS; NITROGEN; CRITERIA; SYSTEMS AB Reported increases in crop yields over the first few years of organic farming (especially during the 3-year "transitional" period established in US law) have been attributed to gradual improvements in soil properties, such as the capacity of the soil microbial community to mineralize N or to suppress disease. To test the hypothesis that yield increases with years of organic farming are due to improvements in soil properties, we compared identically managed organic and transitional plots differing only in duration of organic management (>5 versus <1 year). Conventional plots were included for reference purposes. There was no difference in tomato (Lycopersicon esculentum Mill.) growth or yield between established organic and first-year transitional plots, but both outperformed the comparable conventional system. Even no-compost subplots within the transitional plots had yields similar to established organic plots, so the yield advantage relative to conventional plots was apparently due to beneficial effects of a winter legume cover crop in a wet year. Soil inorganic N did not differ between transitional and organic plots. Conventional and organic plots differed in soil microbial community composition, but transitional plots were not intermediate between conventional and organic. In the second year of the organic transition, when maize (Zea mays L.) was grown, yields were again not significantly different from the established organic system. This result is inconsistent with the hypothesis that yield-limiting differences in soil quality between organic and conventional systems take at least 3 years to develop. An alternative hypothesis, not tested directly, is that previously reported yield increases result from improved management with increasing experience, not improving soil quality.

Approximately 15% of administered label was recovered in a series of flavonoid-rich fractions varying in composition. Anthocyanins, and monomers to oligomers of proanthocyanidins, were labeled effectively and characterized from both species. Most of the proanthocyanidin oligomers were based on the flavan-3-ols (+)-catechin and (-)-epicatechin. Cyanidin and peonidin glycosides were the dominant forms of anthocyanins in both species. Whereas the predominant form of flavonoids identified from ohelo cell cultures was proanthocyanidins, grape cell cultures produced mostly anthocyanins. The labeled phytochemicals were produced for use in subsequent in vivo animal feeding studies to gauge their bioavailability and accumulation in target organs.

[C-14]Oleate and [C-14]ricinoleate were incubated individually with soybean microsomal preparations for up to 4 h, and molecular species of PC and AG incorporated were identified and quantified by HPLC. The activities of acyl CoA:IysoPC acyltransferase and phospholipase A(2) are in general not affected by the fatty acid (FA) chain at the sn-1 position. However, comparison between oleate and ricinoleate revealed that different FA incorporated at sn-2 of PC showed some different selection of the molecular species of lysoPC. The incorporation of [C-14]ricinoleate into triacylglycerols (TAG) was slightly better than that of [C-14]oleate and indicated that soybean was capable of incorporating ricinoleate into TAG when ricinoleate can be produced endogenously in a transgenic soybean. The incorporation of FA into TAG in soybean microsomes was much slower than that in castor microsomes. C1 USDA ARS, Western Reg Res Ctr, Albany, CA 94710 USA.

Calcium caseinate/glycerol solutions were wetted and spread on polyethylene or Mylar belts and were readily removed after forming films. A Meier rod was used to spread the solution onto the belt. Feed rates were 3.3 and 5 g/cm, The resulting films using the polyethylene belt had a tensile strength of 5 MPa and 30% elongation with thickness of 0.14 mm. When the glycerol concentration was adjusted, the process produced films with properties similar to those previously reported for a batch process. It is anticipated that this process will apply to other proteins. C1 USDA ARS, Eastern Reg Res Serv, Dairy Proc & Prod Res Unit, Wyndmoor, PA 19038 USA.

In this study, this analysis is taken a step further by assessing the availability of selected minerals in nopales using an in vitro digestion and dialysis method. The results obtained suggest that although nopales are enriched in a number of minerals, their tissue calcium is not freely available. Microscopic analysis, energy-dispersive X-ray microanalysis, and oxalate measurements suggest that this reduction in available calcium is a result of its sequestration in the form of calcium oxalate crystals. The issue of mineral availability in plant foods is important when the dependence of many populations around the world on plant foods as their main source of minerals and other nutrients is considered.

Bt corn hybrids contain the Cry1Ab protein from Bacillus thuringiensis that controls European corn borers and other stalk-boring pests. Fumonisin levels were frequently lower in grain from Bt hybrids grown in field trials under conditions of natural (FACT trials) or manual insect infestation (university trials). Over three years of FACT trials, there were 126/210 comparisons when fumonisin levels in grain from control hybrids were >2 ppm, exceeding U.S. FDA guidance levels of 2 ppm for human food. Grain from Bt hybrids was at or below 2 ppm of fumonisins for 58 of the 126 comparisons. The use of Bt hybrids can increase the percentage of corn grain that would be suitable for use in food and feed. C1 Monsanto Co, Prod Safety Ctr, St Louis, MO 63167 USA.

Peanut trypsin inhibitors are low molecular mass seed storage proteins. Like peanut allergens, they are stable to acid and heat, resistant to digestion, and can have a negative impact on human health. In peanut, five Bowman-Birk trypsin inhibitors (BBTI) have been isolated and amino acid sequences published. However, to date, no peanut BBTI sequence is available at both the cDNA and the genomic levels. The objectives of this investigation were (i) to synthesize degenerate oligonucleotides based on conserved regions of published amino acid sequences of BBTI, BII, and BIII; (ii) to isolate, sequence, and analyze at least one positive peanut trypsin inhibitor cDNA clone using the synthesized P-32-labeled oligonucleotides as probes; and (iii) to determine its trypsin inhibitory activity. Thirty-two degenerate oligonucleotides DNA primers of 24 nucleotides each were synthesized based on the published amino acid sequences of peanut BBTI, and two were selected as probes to screen a peanut Lambda gt 11 cDNA library. Three putative positive clones were isolated, purified, and subcloned, and one was sequenced. Sequence analysis revealed a partial cDNA clone of 643 bp with a start codon. This clone shares 93 and 96% nucleotide sequence homology with peanut allergens Ara h 3 and Ara h 4 cDNA clones, respectively. A trypsin inhibitor assay revealed that peanut allergen Ara h 3 has a trypsin inhibitory activity of 11 238 TIA/ mg protein. We concluded that peanut allergen Ara h 3 may also function as a trypsin inhibitor. C1 Alabama A&M Univ, Dept Food & Anim Sci, Food Biotechnol Lab, Normal, AL 35762 USA.

The objective of this study was to determine if there are genetic differences in rumen degradability of the protein in red clover forage. Field grown forage was harvested from 133 red clover entries (117 plant introductions and 16 cultivars or experimental lines) plus one cultivar of lucerne (Medicago saliva L.). Forages were analyzed for total N and for crude protein (CP; N x 6.25) that was undegraded at 0 h, as well as for rate of protein degradation and rumen protein escape estimated using a rumen in vitro system. There were small but significant (P = 0.007) differences in total N among the 133 red clover entries but no differences in proportion of CP that was undegraded at 0 h. Protein degradation rate was more rapid for the lucerne cultivar than for any of the red clover entries; this difference was significant (P < 0.05) for 132 of the red clovers. Protein degradation rate ranged from 0.088 to 0.146/h and rumen protein escape ranged from 287 to 409 g CP/kg CP among red clover entries; effect of accession was highly significant (P < 0.001) for both traits. The frequency distributions for the red clover entries for protein degradation rate and rumen protein escape were normal, showing relatively little skewness. The consistency and distribution of these results suggested that conventional plant breeding techniques could be used to develop lines of red clover forage with improved protein utilization in ruminants.

Such grading of fish that may exhibit sexually dimorphic growth could result in changing the sex ratio of populations raised for food production. A preferred gender exists for most aquaculture species. We have found that, during the first year, male sunshine bass appear to grow faster than females; however, females grow faster during the second year and are usually heavier when the fish are harvested. Feeding 17-alpha-methyltestosterone did not increase the growth of fingerling fish; however, feeding estradiol decreased growth, apparently by decreasing feed consumption. Immersion treatment of 4-day-old fry for up to 8 h with 17alpha-methyltestosterone or estradiol did not change the sex ratio. Treatment of 60- or 103-day-old fish for 40 days with estradiol in the feed resulted in all female fish. 17alpha-methyltestosterone treatment during the earlier period resulted in intersex fish, and treatment of 103-day-old fish did not change the sex ratio. Direct feminization with estradiol can be achieved during a period of development in which direct masculinization with 17alpha-methyltestosterone is not effective. Published by Elsevier B.V.

Severity, 3-week-old, SEW pigs were randomly assigned to one of the five groups. Pigs in group 1 (n = 14) served as the negative controls, group 2 pigs (n = 14) were inoculated with PCV2, group 3 pigs (n = 12) were inoculated with PPV, groups 4 (n = 16) and 5 (n = 14) pigs were inoculated with both PCV2 and PPV. Pigs in groups 1-3 and 5 were vaccinated with two doses of a killed parvovirus-leptospira-erysipelothrix (PLE) vaccine prior to inoculation. The PCV2/PPV-coinfected pigs (groups 4 and 5) had significantly (P < 0.05) higher and more persistent fevers than the singular PCV2-infected pigs. One pig in each of the coinfected groups developed clinical disease (fever, respiratory disease, jaundice, weight loss) consistent with PMWS. Lymphoid depletion was significantly (P < 0.05) more severe in the dually-infected pigs at 42 days post-inoculadon (DPI). Vaccinated, coinfected pigs (group 5) remained viremic significantly (P < 0.05) longer and had higher copy numbers of genomic PCV2 DNA in sera at 28, 35, and 42 DPI compared to the unvaccinated coinfected pigs (group 4).

Independent field and laboratory experiments were used to measure the effects that the commonly used herbicides prosulfuron and metolachlor have on trace gas fluxes (CO2, N2O, and CH4) from fertilized soil of the Colorado shortgrass steppe. Separate sample plots (1 m(2)) on tilled and no-till soil at the sites included the following treatments: 1) a control without fertilizer or herbicide, 2) a fertilized (NH4NO3 equivalent to 244 kg ha(-1)) control without herbicide, 3) and fertilized plots amended with an herbicide ( prosulfuron equivalent to 0.46 kg ha(-1) 57% by weight active ingredient or metolachlor equivalent to 5.7 L ha(-1), 82.4% by weight active ingredient). During an initial study of one year duration, measurement of gas exchange revealed that prosulfuron-amendment stimulated N2O emissions and CH4 consumption by as much as 1600% and 1300% during a single measurement, respectively. During a second set of flux measurements beginning in August 2001, more frequent weekly measurements were made during a twelve week period. From this second study an increased N2O efflux and CH4 uptake occurred after a 7-week lag period that persisted for about 5 weeks. These changes in gas flux amounted to an overall increase of 41% and 30% for N2O emission and CH4 consumption, respectively. The co-occurrence of stimulated N-2O and CH4 fluxes suggests a similar cause that is related to prosulfuron degradation. Evidence suggested that prosulfuron degradation stimulated microbial activity responsible for trace gas flux. Ultimately, prosulfuron-amendment led to an -50% reduction in the global warming potential from N2O and CH4 fluxes at this field site, which is equivalent to a reduction of the global warming potential of 0.18 mols CO2 m(-2) d(-1) from these gases. Metolachlor application did not significantly affect the trace gas fluxes measured. These results demonstrate the potential impact that pesticides have on trace gas fluxes from agricultural soils, which could mean that the effects of other agricultural practices have been over or under estimated.

Pesticides are used as management tools in crop production, but little is known about their effects on soil-atmosphere exchange of CO2, N2O, and CH4. Field studies described in this paper determined the effect of two commonly used fungicides, mancozeb and chlorothalonil, on trace gas exchange. Separate experimental plots, 1 m 2, were established in nitrogen fertilized no-tilled native grassland and tilled soils with and without fungicide application. Two studies were conducted. The first study was initiated in June 1999 and lasted for 1 year with monthly flux measurements from tilled and no-till soils. The second study commenced in August 2001 with twelve weekly measurements from tilled soils only. From both studies mancozeb suppressed emissions of CO2 and N2O in the tilled soil by an average of 28% and 47%, respectively. This suppression corresponded with efficacy periods of 14-29 and 56-77 days, respectively. From the no-till soils mancozeb decreased CO2 and N2O emissions by 33% and 80% for periods of 29 and 94 days, respectively. Mancozeb inhibited CH4 consumption in the first study by 46% and 71% in the tilled and no-till soil for periods of 8 and 29 days, respectively, but had no effect in the second study. From both studies chlorothalonil initially suppressed CO2 and N2O emissions and enhanced CH4 uptake in the tilled soil by an average of 37%, 40%, and 115%, respectively. These effects corresponded with efficacy periods of 14-29, 21 - 56, and 1 - 14 days, respectively. In the no-till soil chlorothalonil inhibited CO2 and N2O emissions and enhanced CH4 uptake by 29%, 48%, and 86% for periods of 29, 56, and 56 days, respectively. Following the initial period of suppression, chlorothalonil subsequently enhanced N2O emissions in the tilled soil by an average of 51% and in the no-till soil by 81% before returning to near background levels. The beginning of increased N2O emissions from the chlorothalonil-amended plots corresponded with a maximum soil concentration of the chlorothalonil degradate, 4-hydroxy-2, 5, 6-trichloroisophthalonitrile. The site specific global warming potential (GWP) resulting from the fluxes of CO2, N2O, and CH4 from all soils was determined to decrease by an average 26% and 21% as a result of a single application of mancozeb or chlorothalonil, respectively. The decrease in CO2 emissions in the fungicide-amended plots potentially could result in the conservation of as much as 1200 and 2400 kg C ha(-1) yr(-1) organic carbon in the tilled and no-till plots, respectively. Therefore it is feasible that application of certain fungicides to agricultural soil might lead to enhanced soil carbon sequestration and thus have additional positive effects on atmospheric CO2 concentrations.

To better understand the pathogenesis and immunity to the 1918 pandemic virus, we generated recombinant influenza viruses possessing two to five genes of the 1918 influenza virus. Recombinant influenza viruses possessing the hemagglutinin (HA), neuraminidase (NA), matrix (M), nonstructural (NS), and nucleoprotein (NP) genes or any recombinant virus possessing both the HA and NA genes of the 1918 influenza virus were highly lethal for mice. Antigenic analysis by hemagglutination inhibition (HI) tests with ferret and chicken H1N1 antisera demonstrated that the 1918 recombinant viruses antigenically most resembled A/Swine/Iowa/30 (Sw/ Iowa/30) virus but differed from H1N1 viruses isolated since 1930. HI and virus neutralizing (VN) antibodies to 1918 recombinant and Sw/Iowa/30 viruses in human sera were present among individuals born before or shortly after the 1918 pandemic. Mice that received an intramuscular immunization of the homologous or Sw/Iowa/30-inactivated vaccine developed HI and VN antibodies to the 1918 recombinant virus and were completely protected against lethal challenge. Mice that received A/PR/8/34, A/Texas/36/91, or A/New Caledonia/20/99 H1N1 vaccines displayed partial protection from lethal challenge. In contrast, control-vaccinated mice were not protected against lethal challenge and displayed high virus titers in respiratory tissues. Partial vaccine protection mediated by baculovirus-expressed recombinant HA vaccines suggest common cross-reactive epitopes on the H1 HA. These data suggest a strategy of vaccination that would be effective against a reemergent 1918 or 1918-like virus. C1 USDA ARS, SE Poultry Res Lab, Athens, GA 30605 USA.

Limits for eutrophication of flowing waters not discharging directly into water bodies of 0.01 mg dissolved reactive P (DRP) and 0.1 mg total P (TP) l(-1), can be readily exceeded in areas with P enriched soils. Little information is available on how long P discharge will remain above environmental thresholds, particularly for subsurface flow. Thus, this work looked at the effect of applying P (as mineral fertilizer, dairy manure and compost, and poultry manure and compost at 0-200 kg P ha(-1) per year for 5 years), to a Hagerstown silt loam on P leached from lysimeters (30 cm deep) with rainfall generating,high flow (330 cm per 5 months; high-flow lysimeters) and low flow conditions (165 cm per 5 months; low-flow lysimeters). For high-flow lysimeters, most P was leached from dairy compost (88 mg DRP and 148 mg TP) and poultry manure (41 mg DRP and 83 mg TP) amended soils compared with mineral superphosphate (26 mg DRP and 43 mg TP) and dairy manure (26 mg DRP and 59 mg TP). Similar trends but lower losses were observed for the low-flow lysimeters. Among the 50 lysimeters, Mehlich-3 soil P thresholds of 100 and 130 mg kg(-1) occurred for DRP and TP, respectively. Above these thresholds, DRP and TP loss was enhanced. The decrease of P concentrations leached (inorganic and organic P forms, y) with time (t, days) could be described by a power function (y = alphat(beta)). The rate of decrease in P leached (beta) was quicker at high than low flow rates. Using this equation, it was estimated that for a soil of 100 mg kg(-1) Mehlich-3 P under high-flow conditions would take about 3 years for DRP to fall below 0.01 mg L-1 and 6 years under low flow conditions. Clearly, once soil P concentrations become elevated via management, it can take several years for P enriched drainage waters to decline below "acceptable" levels. (C) 2003 Elsevier B.V.

Until recently, the Universal Soil Loss Equation (USLE) has been used as a soil erosion model on the field scale. Since then, more process-based soil erosion models have been developed such as the 'Water Erosion Prediction Project (WEPP) model. This new technology represents the state-of-the-art in modeling the effects of changes in surface characteristics on soil erosion. In this study, the capability of the WEPP hillslope interface in version 2002.07 for simulating runoff and soil loss, applied to selected runoff plots, was tested in the Tuxtlas, Veracruz, Mexico by comparing runoff and soil loss from live tree hedgerow terraces (TMV-TA 1.0 m) as an erosion control method with a conventional tillage (CT) practice. The breakpoint climate data generator (BPCDG) was used to generate the climate file. When compared to measured data, the CT WEPP estimated runoff and soil loss were low, whereas the TMV-TA 1.0 m WEPP estimated soil loss was high. For soil loss, the model over-predicts small events and under-predicts the larger ones. The Nash-Sutcliffe model efficiencies for predicting runoff and soil loss using an optimization method were 0.84 and 0.86 for the TMV-TA 1.0 m and 0.88 and 0.84 for the CT. The sensitivity analysis and calibration process show that the model is very sensitive in the effective hydraulic conductivity value and erodibility parameters. This study showed that in order to apply the WEPP model, revision of data collection system is necessary for studying the hydrologic and erosion soil processes with reliable estimates of soil erodibility parameters, effective hydraulic conductivity, and crop and managements parameters, in order to provide realistic estimates of runoff and soil loss.

To alleviate environmental stress-related yield reductions, a better understanding of the relative sensitivities of pollen development, dehiscence, pollen germination, pollen tube growth, fertilization, and subsequent boll development is needed. Progress in identifying the sensitivities of these developmental stress responses has been hampered in part by the lack of a rapid and reliable method of germinating cotton (Gossypium spp.) pollen in vitro. The present study describes the development of an in vitro cotton pollen germination system that provides improved pollen germination levels and pollen tube growth over existing methods. This procedure was used to evaluate the temperature sensitivity of pollen from greenhouse and field-grown cotton. The medium comprises 10% (wtv) agarose (pH 7.6), 25% (wtv) sucrose, 0.52 mM KNO3,3.06 mM MnSO4,1.66 mM H3BO3,0.42 mM MgSO(4)(,)7H(2)O, and 1.0 muM A(3) gibberellic acid. The medium is overlayed with a layer of 1.5% agarose before use. Optimum pollen germination and rapid tube elongation occurred between 28 and WC under 80% relative humidity. Decreased pollen germination occurred at temperatures above 37degreesC, and decreased tube elongation occurred at temperatures above 32degreesC. Evaluation of pollen, taken at 1400 h from field-grown cotton plants, showed that pollen from flowers exposed to direct sunlight had reduced viability compared with pollen from flowers inside the canopy. This could be attributed to the fact that flowers from field-grown irrigated cotton plants exposed to full sunlight experienced internal temperatures as high as 39degreesC, well above the 28 to 31degreesC optimum for pollen germination.

The objectives of this study were to determine the effect of winter cover crops on thrips populations in cotton and to assess the yield and fiber quality response to cover crops and N fertilizer rate with and without thrips protection. A field experiment was conducted on a Bonneau loamy sand soil (loamy, siliceous, thermic, Arenic Paleudult) from 1996 through 1998. Treatments were cover crops, N fertilizer rate, and aldicarb rate. Cover crops were rye (Secale cereale L.), crimson clover (Trifolium incarnatum L.), a clover + rye mixture, and winter fallow. Nitrogen levels were 0, 78, and 112 kg N ha(-1). Aldicarb levels were 0 and 1.18 kg a.i. ha(-1). Aldicarb reduced thrips populations. For plots without aldicarb, differences among winter covers occurred at one sampling time in 1998 when fallow had more thrips than the other three winter covers. Aldicarb increased yield by 9% in 1996, 48% in 1997, and 35% in 1998. In 1997 and 1998, yield increases with aldicarb were greater in the winter cover and N treatment combinations that provided higher total N to the crop. The 0 kg N ha(-1) rate tended to have lower yield, fiber length, length uniformity, fiber strength, micronaire, and Hunter's +b than the other two N rates. Aldicarb generally increased the value of these fiber properties each year. Including agronomic practices in assessing control measures may improve integrated pest management strategies for thrips in conservation tillage systems. C1 USDA ARS, Florence, SC 29501 USA.

Objectives were to document the effects of moisture deficit stress on reproductive growth, tint yield, yield components, boll distribution, and fiber quality. Field studies were conducted from 1998 through 2001 utilizing eight diverse genotypes, which were grown under both dryland and irrigated conditions. Weekly white bloom counts, nodes above white bloom, lint yield, yield components, end-of-season plant mapping, and fiber quality data were collected. Genotypes responded similarly to the two soil moisture regimes for all of the parameters evaluated. Irrigation delayed cutout, the slowing of vegetative growth due to strong reproductive demand for assimilate, an average of 6 it. This delayed maturity enabled those plants to sustain flowering later in the growing season compared with dryland plants. During the years when sufficient moisture deficits occurred, the lint yield of dryland plants was reduced 25%, primarily because of a 19% reduction in number of bolls. Irrigated plants produced more bolls at higher plant nodes (>Node 10) and at the more distal positions (greater than or equal to2) on the sympodial branches than did the dryland plants. Irrigation did not affect most fiber traits, but 3 out of 4 yr of irrigation produced approximately 2% longer fiber. Production of more bolls higher up the plant and further out the fruiting branch with irrigation indicates that these areas on the plant are where high yields need to be stabilized.

Merr.] production in the Midwest. Benefits of no-till vary with latitude and cropping system. This study was conducted to evaluate the influence of seasonal temperature and precipitation on the effects of primary tillage (plow, disk, chisel, subsoil, ridge-till, and no-till) and rotated and continuous corn and soybean production under rainfed conditions over 16 yr in southeastern Nebraska. Corn and soybean produced less grain with greater summer temperatures. Corn yield increased with less spring and more summer rainfall. Tillage and rotation practices affected corn grain yield; but only rotation affected soybean yield. Corn produced less grain with no-till than with plow. The tillage X year interaction was significant for both crops; the yield advantage for plow was less during seasons with warmer springs. Soybean grain yield was less responsive to favorable environments with the chisel than other tillage treatments. Grain yield was greater with rotation than continuous cropping for both corn (7.10 vs. 5.83 Mg ha(-1)) and soybean (2.57 vs. 2.35 Mg ha(-1)). The benefit of rotation in terms of grain yield was greatest for corn during years with cool springs. The benefit of rotation for soybean grain yield did not vary with weather conditions. Seasonal temperature and rainfall patterns influenced the effects of tillage and rotation on corn yield. In. contrast, for soybean, only the pattern of temperature influenced the effect of tillage on yield. C1 Univ Nebraska, Dept Agron & Hort, Lincoln, NE 68583 USA.

The objective of this study was to differentially label dairy manure N components with the stable isotope N-15 for direct measurement of manure N cycling in soils and availability to crops. Dairy urine and fecal N components (microbial and undigested feed N) were differentially labeled by feeding either N-15-enriched forage or urea to mature dry dairy cows (Bos taurus). Nitrogen-15-enriched ammonium sulfate was used to label alfalfa (Medicago sativa L.) hay and corn (Zea mays L.) silage. These N-15-enriched forages or either single or multiple doses of N-15-enriched area were fed for 2 to 3 d, and feces and urine were collected separately for 8 d after the initiation of N-15 feeding. For both labeling techniques, N-15 appeared first in urine followed by fecal microbial and undigested feed N. For the forage method, the proportionate combination of feces excreted before and after peak N-15 excretion levels would achieve uniform labeling of fecal N components. For the area method, no undigested feed N in feces was labeled since N-15-enriched forage N was not fed. The choice of which labeling method to use depends on the intended use of labeled manure. Manure enriched using the forage method and high levels of manure N-15 enrichments should be used for long-term manure N cycling studies. Manure enriched using the urea method and lower N-15 enrichments could be used in shorter-term studies. C1 USDA ARS, Dairy Forage Res Ctr, Madison, WI 53706 USA.

This study was conducted to evaluate residual effects of annual or biennial applications of N- and P-based composted and noncomposted beef cattle (Bos taurus) feedlot manure, chemical fertilizer, and no-treatment check on corn (Zea mays L.) production and soil properties. Manure and compost were applied from 1992 to 1995, and the residual effects were determined from 1997 to 1999. Residual effects of N- and P-based manure and compost applications on corn grain yield and N uptake lasted for at least one growing season while the effects on soil properties were longer lasting. Soil P can contribute to crop P uptake for >4 yr after N-based manure or compost application had ceased. The residual effects of manure and compost applications significantly increased soil electrical conductivity and pH levels and plant-available P and NO3-N concentrations. Four years after the last application, P leaching to a soil depth of 45 to 60 cm was observed with N-based manure or compost application. No residual effects of manure and compost applications on soil NH4-N were observed. Averaged across years, soil total C concentrations or quantities were not different among the treatments, indicating that total C was not a sensitive indicator. Residual effects of N- or P-based manure or compost application increased crop production for one year and influenced soil properties for several years.

These augment the demand for agricultural products and have led to the expansion, intensification, and often closer integration of crop and livestock production systems. The transition of crop and livestock production from the current relatively extensive, low input/output modes of production to more intensive, higher input/output modes of production presents numerous challenges to the achievement of required long-term production increases from these farming systems. This paper provides an overview of the challenges facing agricultural production in semiarid SSA with a focus on West Africa. A description of mixed crop-livestock farming systems and their evolution is followed by an overview of the principal linkages between crops and livestock: income, animal power, feed, and manure. The most detailed discussions relate to nutrient cycling in these farming systems. Most livestock derive their feed almost exclusively from natural rangeland and crop residues, and livestock manure is a precious soil fertility amendment. However, most farmers have insufficient livestock and therefore manure to sustain food production. Nutrient harvests from cropland often exceed nutrient inputs, and soil nutrient depletion is a principal concern. The paper concludes with a discussion of strategies that may improve the productive capacity of these mixed farming systems. C1 USDA ARS, US Dairy Forage Res Ctr, Madison, WI 53706 USA.

Grass hays were compared for nutrient removal in an effluent spray field. Eastern gamagrass (Tripsacum dactyloides L.), indiangrass [Sorghastrum nutans (L.) Nash], johnsongrass [Sorghum halepense (L.) Pers.], switchgrass (Panicum virgatum L.), and common and 'Coastal' bermudagrass [Cynodon dactylon (L.) Pers.] were grown on a Brooksville silty clay (fine, montmorillonitic, thermic Aquic Chromuderts) in Mississippi. The field produced johnsongrass hay and received swine (Sus scrofa domesticus) effluent (estimated 371, 61, and 629 kg ha(-1) yr(-1) of N, P, and K, respectively) for 8 yr before the study. In the 3-yr study, common bermudagrass produced 4.6 to 15.0 Mg dry matter (DM) ha(-1) yr(-1) and was not different from Coastal bermudagrass (5.2 to 13.7 Mg ha(-1) yr(-1)). Highest annual DM yields of johnsongrass, eastern gamagrass, switchgrass, and indiangrass were 9.7,9.5,9.1, and 5.5 Mg ha(-1) yr(-1), respectively. Highest annual uptakes of N by common and Coastal bermudagrass, johnsongrass, eastern gamagrass, switchgrass, and indiangrass were 314, 280, 1889 181, 167, and 106 kg ha(-1), respectively. Respective highest annual uptakes of P were 44, 35, 23, 21, 19, and 14 kg ha(-1). Uptakes of Ca, K, Mg, Cu, Fe, Mn, and Zn were as high or higher in common bermudagrass as in the other grasses. Dry matter yield of common bermudagrass was correlated (r = 0.99, P = 0.0001) with uptakes of N, P, and K. Replacing johnsongrass with bermudagrass would increase annual DM yield in the field 155 to 249% and P uptake 194 to 259%.

This study was conducted to develop and evaluate a regression model to predict corn grain yield at a midpoint in the growing season based on the current year's cumulative thermal factors and N fertility levels. The relationship among early-season growing conditions, N fertility, and corn grain yield under continuous corn production and sprinkler irrigation was investigated from 1990-1995 in southeastern North Dakota. Fertility levels on small plots ranged from 0 to 224 kg ha(-1) applied N. There was a wide range of cumulative growing degree days (GDD) and evapotranspiration (ET) during the study period. Least-squares regression was used to develop equations to predict, on 10 July, grain yield based on cumulative ET or GDD from 1 May to 10 July and soil N plus applied N. Yields predicted on 10 July corresponded well to individual observed yields (r(2) = 0.80), and predicted optimum yield (Y-OPT) was highly correlated to observed Y-OPT (r(2) = 0.885). The model could provide a season-specific yield potential used to modify N application during the growing season, resulting in fertilizer savings in the extreme years when cool early-season weather limited yield potential or fertilizer increases to take advantage of optimum growing conditions and increase yields. Including meteorological measurements can improve fertilizer management decisions by providing midseason adjustments to fertilizer recommendations.

A field experiment was conducted to quantify input, output, and the year-round major plant nutrient dynamics in a fine sandy loam soil supplied with 15.75 Mg ha(-1) yr(-1) broiler litter. Soil samples were collected from pre-established plots of common bermudagrass [Cyno-don dactylon (L.) Pers.] and hybrid bermudagrass cultivars Coastal and Tifton 85 for nutrient analysis. Coastal and Tifton 85 produced significantly greater annual dry matter yield (16 948 and 18 772 kg ha(-1)) than common bermudagrass (11238 kg ha(-1)). Tifton 85 was most efficient and removed 344, 58, and 472 kg ha(-1) N, P, and K, respectively. The removal efficiency of these nutrients for Tifton 85 was 73, 18, and 114%, respectively. Soil pH varied from 6.0 to 6.6 until it decreased unexpectedly to 5.6 by the end of 2001. Total soil C increased from 11.4 g kg(-1) to 17.9 g kg(-1) by the end of the second year. At all sampling dates, the NO3-N concentration was greater than NH4-N while total N decreased during the maximum uptake in late spring and summer. Both total P and Mehlich-3 extractable P concentrations increased mainly in the 5- to 10-cm depth, indicating slight leaching of P. Results indicated that top yield from hybrid bermudagrass cultivars is possible with broiler litter as a sole fertilizer source. However, considerable nutrient imbalances in soil may occur in the long term if improper litter rates are used. C1 USDA ARS, Waste Manage & Forage Res Unit, Bowling Green, KY 42101 USA.

The objectives of this research were to determine how tillage and composted swine (Sus scrofa L.) manure affected yield of corn (Zea mays L.), soybean [Glycine mar (L.) Merr], and wheat (Triticum aestivum L.) and soil concentrations of OM, P, and K. A corn-soybean-wheat/clover (Trifolium spp.) rotation, in all phases, was initiated in 1998 in plots that had been managed with moldboard plow (MP), chisel plow, or no-till since 1988. Moldboard and chisel plow increased corn yield in the first year of the study vs. no-till. Thereafter, tillage did not affect yield on plots that received compost. Tillage X compost interactions during the last 2 yr of the study increased no-till compost yield 11% vs. no compost. Soybean yield was similar in no-till and chisel compost plots during the study period and between MP and no-till in 3 of 4 yr. Tillage X compost interactions were observed in 2 of 4 yr that increased no-till compost yield 9% vs. no compost. Averaged across all crops and tillage, compost-amended soil had 63 g kg(-1) OM and 164 mg kg(-1) P vs. 56 and 55 in no compost. Corn and soybean producers can enhance yield with multiple compost applications and eliminate yield differences between conventional and no-till systems. Nevertheless, compost application for soil OM enhancement must be balanced with P input to minimize the potential for excessive soil P accumulation.

'Moonlight', 'NorthStar', and 'P-105' Kentucky bluegrass (KBG) were grown in solution culture and exposed to salinity levels of 2.0, 5.0, 8.0, 11.0, and 14.0 dS m(-1) for 12 wk. All cultivars exhibited increased leaf firing with increasing salinity. However, Moonlight and NorthStar exhibited less leaf firing than P105 at all salinity levels. The salinity levels that caused 25% shoot growth reduction were 4.9 dS m(-1) for NorthStar and Moonlight and 4.1 dS m-1 for P105, indicating that Moonlight and NorthStar have better salinity tolerance than P105. When salinity level was in the range of 2.0 to 8.0 dS m(-1), Moonlight produced 1.9-fold more root mass than NorthStar, and NorthStar exhibited 3.9-fold more root mass than P105. When salinity exceeded 8.0 dS m(-1), NorthStar had similar root mass as Moonlight, and both showed greater root mass than P105. Cultivar P105 had a higher C isotope discrimination (Delta) than Moonlight and NorthStar under nonsaline conditions (<2 dS m(-1)) but a lower Delta than Moonlight and NorthStar at 11.0 dS m(-1) salinity. The great reduction in Delta of P105 as salinity increased suggests that salinity induced a greater degree of stomatal resistance that provided less opportunity for discrimination against the heavier isotope. Carbon isotope discrimination may serve as a useful selection criterion in breeding efforts to develop salt tolerant KBG.

Merr.] damaged by deer (Odocoileus virginianus). The objectives of this research were to (i) develop a modeling tool using differences between biomass removal treatments and controls for pod density and seed yield to quantify yield loss and (ii) assess the tool using double crossvalidation. Model development using linear and polynomial exponential (PE) equations was accomplished using 1998-2001 data from studies examining different biomass removal treatments, varieties, and row spacings. The PE model had a slightly higher coefficient of determination (R-2 = 0.93) than the linear model (R-2 = 0.92). Double cross-validation of both models produced strong relationships with high coefficients of determination and predictive ability; however, the model performance statistics indicated that the PE model had higher coefficients of determination, lower mean bias error, and more robust slope estimates than the linear model. Depending on the end-user, the simplicity of the linear model should be carefully considered in weighing the benefits of each tool. Nevertheless, these approaches provide robust tools that are not sensitive to moderate abiotic fluctuations, varying cultural practices, and a wide range of temporal biomass removal. Validating the relationship using additional data should be the next step before implementation. C1 USDA ARS, Natl Soil Tilth Lab, Ames, IA 50011 USA.

It is possible that variables such as sex, food intake, or both may in part explain this poor coupling. Objective: This study was designed to show the relation between PAEE and %BF and to determine whether sex, food intake, or both influence the strength of the relation. Design: We used doubly labeled water or energy intake balance, indirect calorimetry, dietary interview, and dual-energy X-ray absorptiometry to measure total energy expenditure (TEE), resting energy expenditure (REE), food intake, and %BF, respectively, in 91 healthy persons (women: aged 48 y, 38.6%BF, n = 47; men: aged 47 y, 24. 1 %BF, n = 44). Results: TEE, PAEE, and REE were significantly lower in women than in men. TEE was related to %BF in women (r = 0.53, P < 0.0001) but not in men (r = -0.22, P > 0.05). The relation between PAEE and %BF was significant in men (r = -0.34, P < 0.03) but not in women. PAL was also significantly related to %BF in men (r = -0.36, P < 0.02) but not in women. Macronutrient intake (% of total energy) did not differ significantly between the sexes, but carbohydrate (r = -0.44, P < 0.003) and fat (r = 0.31, P < 0.04) intakes were significantly related to %BF in women. Conclusions: These results suggest that the relation between PAEE and %BF is stronger in men than in women. Macronutrient composition seems have a stronger influence on %BF in women than in men.

Mean absolute RMR was 1,167, 1,418, and 1,347 kcal/day, respectively. Absolute RMR was statistically significantly higher at menarche than at 4 yr after menarche despite statistically significantly less fat-free mass (FFM) and fat mass (FM), suggesting an elevation in RMR around the time of menarche. The pattern of change in RMR, adjusted for FFM, log transformed FM, age, race, parental overweight, and two interactions (visit by parental overweight, parental overweight by FFM), was also considered. Adjusted RMR did not differ statistically between the visits for girls with two normal-weight parents. For girls with at least one overweight parent, adjusted RMR was statistically significantly lower 4 yr after menarche than at premenarche or menarche. Thus parental overweight may influence changes that occur in RMR during adolescence in girls. C1 Tufts Univ, Sch Med, Jean Mayer USDA HNRCA, Dept Epidemiol, Boston, MA 02111 USA.

While both types of periderm form from a phellogen layer that serves as a lateral meristem, there has been little research done on comparing the biochemical processes and steps involved in the maturation of the two types of periderm. Here, we use immunological techniques to compare some of the cell wall changes during wound and native periderm maturation. Consistent with our recent work on native periderm, we demonstrate that toluidine blue O is also useful for distinguishing between suberized and non-suberized cells in wound periderm. More importantly, we use the immunological probes JIM5 and JIM7 to show that there is no increase in either un-esterified or esterified homogalacturonan pectin epitopes in phellogen walls accompanying wound periderm maturation. In contrast, as we previously described, native periderm maturation and resistance to excoriation (skinning) is accompanied by an increase in relatively un-esterified and esterified homogalacturonan pectin epitopes in the walls of phellogen cells. These results demonstrate that the biochemical processes responsible for maturation and resistance to excoriation differ between native and wound periderm. This dissimilarity between wound and native periderm maturation demonstrates the potential limitations in applying the wound periderm model to research on native periderm.

This increase was found only in genotypes that are able to cold acclimate and was reversible on deacclimation suggesting a link between the accumulation of 18:2 and acquisition of freezing tolerance. The present study was aimed at understanding the association between the induction of stearoyl-ACP (acyl carrier protein) (Delta9) desaturase and the ability to cold acclimate. Our approach was to study the induction of Delta9 desaturase at the transcript level using potato Delta9 desaturase gene-specific primers and reverse transcription polymerase chain reaction (RT- PCR). For this purpose, total RNA from Solanum tuberosum (cold sensitive, unable to acclimate) and Solanum commersonii (cold tolerant, able to cold acclimate) was extracted before and after cold acclimation. RT-PCR produced a single band and sequence analysis confirmed that the amplified band was Delta9 desaturase. While the cold acclimating species, Solanum commersonii, exhibited an increase in Delta9 desaturase transcript levels after cold acclimation, the cold non-acclimating species, Solanum tuberosum, exhibited no change. Our results show that the increase in Delta9 desaturase gene transcripts during cold acclimation is associated with the cold acclimation response in potato.

For diseases whose progression can be described by sigmoid curves, an estimate of the area under the disease progress curve from two data points may provide as much information as from repeated assessments. Twenty-three clones were planted in a randomized complete block design in Hastings, FL, in 1997 and evaluated for percent diseased foliage 14 times during a 31-day period after late blight was first noticed in the plots. The area under the disease progress curve (AUDPC) was calculated for all 14 assessments. The AUDPC was also calculated for nine sub-sets of the original data set. There was a high correlation between all the methods in the calculation of the AUDPC. The AUDPC calculated based on two dates (representing the beginning of the epidemic and the time until two of the clones were dead from late blight) was as informative as the AUDPC calculated on the entire data set. The AUDPC could be calculated based on any two dates from this time frame as long as one date was shortly after the epidemic started and the other date was as the epidemic was reaching its peak. Much information was lost if AUDPC was calculated based on dates involved only in the early part of the epidemic. A considerable savings in time and effort can be realized by only a few assessments.

Aphids colonized soybean when plants were still small in early July. After a lag of 2 wk, aphid density increased rapidly in late July, reaching a peak of 114 +/- 46 aphids per five soybean plants on 1 August. The population declined to a plateau immediately after this peak and then declined again starting in mid-August, although a second small peak occurred in late August. The finite rate of increase varied from zero-to five-fold, and the aphid seemed to be limited by natural enemies. The main species of natural enemy were the aphid parasitoid Lysiphlebus sp., the aphid predators Propylaea japonica (Thunberg), Scymnus (Neopullus) babai Sasaji, and Paragus tibialis (Fallen). In a field exclosure experiment, A. glycines density in small-mesh cages peaked three-fold higher than in large-mesh cages and 12-fold higher than on uncaged plants, indicating that natural enemies did indeed limit aphid density.

Importation of exotic organisms for biological control is never completely risk-free, but the potential negative impacts of not achieving biological control of invasive pests may exceed the risks associated with a biological control introduction. The potential benefits of biological control include reduced insecticide use and a reduced ability of the invasive pest to impact native flora and fauna, and we outline what the scope of these benefits may be for the soybean aphid. The benefits are only accrued, however, if biological control is successful, so the likelihood of successful biological must also be assessed. Accordingly, we outline some issues relevant to predicting the success of importation biological control of the soybean aphid. We also outline the potential risks to nontarget organisms that would be associated with importation biological control of the soybean aphid. Currently, two parasitoid species, Aphelinus albipodus Hayat and Fatima (Hymenoptera: Aphelinidae) and Lipolexis gracilis Forster (Hymenoptera: Braconidae) have been imported from Asia and have passed through quarantine. We briefly review the biology and host range of these two species. A different strain of A. albipodus that was released against the Russian wheat aphid, Diuraphis noxia (Mordvilko) (Homoptera: Aphididae), in the early 1990s was also found to attack the soybean aphid in the laboratory and has been redistributed from Wyoming to Minnesota and Wisconsin in field releases against the soybean aphid. We discuss our rationale for going forward with this redistribution. C1 Univ Minnesota, Dept Entomol, St Paul, MN 55108 USA. USDA ARS, Beneficial Insects Res Lab, Newark, DE USA.

A total of 215 individuals of one such species, Melanoplus alpinus Scudder, was collected from 43 meadows (5 individuals per meadow) in 10 drainages of four mountain ranges in Wyoming and Montana. This sample structure allows for genetic analysis at four spatial scales: among mountain ranges, among drainages within ranges, among meadows within drainages, and within meadows. We examined whether genetic structuring differed among the sampling scales analyzed and whether present isolation between populations of M. alpinus reflects similar historical isolation. Polymerase chain reaction restriction fragment-length polymorphism analyses were conducted on two mtDNA regions (COI and COII), revealing nine haplotypes among the 215 individuals. DNA sequence analysis of 496 bp of the COI region for 23 individuals representing the various restriction fragment-length polymorphism haplotypes and ranges revealed three major lineages, with divergence rates that have been typically observed between species of Melanoplus. The three lineages may represent three cryptic species or a relatively ancient paraphyly in a single species. Regardless of which of these scenarios is true, analysis of molecular variance suggested that "M. alpinus" was a widely distributed, panmictic species at the end of the last Pleistocene glaciation that has since retreated to montane/alpine meadows of the central and northern Rocky Mountains. The presently fragmented distribution of the species is not indicative of historically similar isolation. The degree of genetic differentiation varied among geographical scales, being greatest among drainages and meadows within mountain ranges. Very little genetic differentiation existed among mountain ranges. C1 USDA ARS, NPARL, Sidney, MT 59270 USA. RP Lockwood, JA (reprint author), USDA ARS, NPARL, 1500 N Cent Ave, Sidney, MT 59270 USA.

Parasitoids recovered from brown citrus aphids in Florida include Lysiphlebus testaceipes (Cresson), Lipolexis scutellaris Mackauer, and Aphelinus gossypii Timberlake. Monitoring the levels of parasitism caused by each species is difficult because the parasitoids must be reared out or dissected from the aphid hosts. A simple and quick molecular approach was developed to detect and distinguish these parasitoids developing within the host aphid. Total genomic DNA was extracted from the brown citrus aphid and each of the three parasitoids and the 18S rRNA gene of each species was amplified by polymerase chain reaction (PCR). The PCR products were sequenced to obtain complete gene sequences for each species. The variable regions V2 of the genes were used to design species-specific primers for detecting and differentiating the three parasitoids. The species-specific PCR amplifications discriminated the parasitoid DNAs from each other and from the host DNA. Detection of L. testaceipes DNA within the host aphid was possible in 8% of samples during the first 2 h after parasitoid oviposition; in 66% of samples after 24 h; in 94% of samples after 48 h; and in 100% of samples after 72 h. The PCR approach described in this study provides earlier and more precise detection of parasitism and determination of species than rearing or dissection methods.

Among these are the polyketide compounds pyoluteorin and 2,4-diacetylphloroglucinol. We provide evidence that pyoluteorin production is influenced by positive autoregulation. Addition of pyoluteorin to liquid cultures of Pf-5 enhanced pyoluteorin production. In addition, pyoluteorin and 2,4-diacetylphloroglucinol mutually inhibit one another's production in Pf-5. For pyoluteorin, both positive autoregulation and negative influences on production by 2,4-diacetylphloroglucinol were demonstrated at the transcriptional level by measuring activity from transcriptional fusions of an ice nucleation reporter gene (inaZ) to three separate pyoluteorin biosynthetic genes. The occurrence of pyoluteorin autoregulation in the rhizosphere was assessed on cucumber seedlings in pasteurized soil with cross-feeding experiments. In the rhizosphere, expression of a pyoluteorin biosynthesis gene by a pyoluteorin-deficient mutant of Pf-5 was enhanced by pyoluteorin produced by coinoculated cells of Pf-5. These data establish that the polyketide pyoluteorin is an autoregulatory compound and functions as a signal molecule influencing the spectrum of secondary metabolites produced by the bacterial cell.

The PCR assays were specific for the respective serogroups, as there was no amplification of DNA from non-O26 and non-O113 E. coli serogroups or from other bacterial genera tested. Using the PCR assays, we were able to detect the organisms in seeded apple juice inoculated at concentration levels as low as less than or equal to 10 CFU/ml. The O26- and O113-specific PCR assays can potentially be used for typing E. coli O26 and O113 serogroups; these assays will offer an advantage to food and environmental microbiology laboratories in terms of identifying these non-O157 serogroups by replacing antigen-based serotyping.

The enzyme containing 657 amino acid residues was homologous to certain animal, plant, and bacterial beta-glucosidases but lacked significant similarity to those from aerobic fungi. Neither cellulose- nor protein-binding domains were found in BgIA. When expressed in Saccharomyces cerevisiae, the enzyme was secreted in two forms with masses of about 110 kDa and also found in two forms associated with the yeast cells. K-m and V-max values of the secreted Bg1A were 0.762 mM and 8.20 mumol/(min(.)mg), respectively, with p-nitrophenyl-beta-D-glucopyranoside (pNPG) as the substrate and 0.310 mM and 6.45 mumol/(min(.)mg), respectively, for the hydrolysis of cellobiose. Glucose competitively inhibited the hydrolysis of pNPG with a K-i of 3.6 mM. beta-Glucosidase significantly enhanced the conversion of cellulosic materials into glucose by Trichoderma reesei cellulase preparations, demonstrating its potential for use in biofuel and feedstock chemical production.

The use of CSL resulted in the production of 6.29 g/L of total acetone-butanol-ethanol (ABE) as compared with 6.86 g/L in a control experiment. These studies were performed at a dilution rate of 0.32 h(-1). The productivities in the control and CSL experiment were 2.19 and 2.01 g/(L(.)h), respectively. Although the use of CSL resulted in a 10% decrease in productivity, it is viewed that its application would be economical compared to P2 medium. Hence, CSL may be used to replace the P2 medium. It was also demonstrated that inclusion of butyrate into the feed was beneficial to the butanol fermentation. A control experiment produced 4.77 g/L of total ABE, and the experiment with supplemented sodium butyrate produced 5.70 g/L of total ABE. The butanol concentration increased from 3.14 to 4.04 g/L. Inclusion of acetate in the feed medium of the immobilized cell biofilm reactor was not found to be beneficial for the ABE fermentation, as reported for the batch ABE fermentation.

The University of Illinois has developed a modified dry grind process that allows recovery of the fiber fractions prior to fermentation. We report here on conversion of this fiber (Quick Fiber [QF]) to ethanol. QF was analyzed and found to contain 32%wt glucans and 65%wt total carbohydrates. QF was pretreated with dilute acid and converted into ethanol using either ethanologenic Escherichia coli strain FBR5 or Saccharomyces cerevisiae. For the bacterial fermentation the liquid fraction was fermented, and for the yeast fermentation both liquid and solids were fermented. For the bacterial fermentation, the final ethanol concentration was 30 g/L, a yield of 0.44 g ethanol/g of sugar(s) initially present in the hydrolysate, which is 85% of the theoretical yield. The ethanol yield with yeast was 0.096 gal/bu of processed corn assuming a QF yield of 3.04 lb/bu. The residuals from the fermentations were also evaluated as a source of corn fiber oil, which has value as a nutraceutical. Corn fiber oil yields were 8.28%wt for solids recovered following prtetreatment. C1 USDA ARS, Natl Ctr Agr Utilizat Res, Peoria, IL 61604 USA.

Uridine diphosphate (UDP)-glucose dehydrogenase is a key enzyme in the biosynthesis of uronic acids. We produced transgenic alfalfa (Medicago sativa) plants expressing a soybean UDP-glucose dehydrogenase cDNA under the control of two promoters active in alfalfa vascular tissues. In initial greenhouse experiments, enzyme activity in transgenic lines was up to seven-fold greater than in nontransformed control plants; however, field-grown transgenic plants had only a maximum of 1.9-fold more activity than the control. Cell-wall polysaccharide content was lower and Klason lignin content was higher in transgenics compared to the nontransformed control. No significant increase in pectin or uronic acids in the polysaccharide fraction was observed in any line. Xylose increased 15% in most transgenic lines and mannose concentration decreased slightly in all lines. Because of the complexity of pectic polysaccharides and sugar biosynthesis, it may be necessary to manipulate multiple steps in carbohydrate metabolism to alter the pectin content of alfalfa.

Collection efficiency of the best screen was compared to string and plastic tapes of several widths. This screen appeared to be nearly as efficient as strings and much better than plastic tapes, based on collection efficiency per unit frontal area. Total spray collected on an array of screens was compared to the total spray emitted from the air atomizing nozzles. Results were compared with the classic results of May and Clifford (1967). The screen collection efficiency was about 120% for 30-mum droplets and 140% for 44-mum droplets, using calculation methods similar to those of May and Clifford. Air velocities were measured with no screens and behind single screens, for a wind tunnel speed of 4 m/s and a nozzle air pressure of 138 kPa (20 psi). Air speed behind screens with a porosity of 39% was about 50% of air speed behind screens with 53% porosity. C1 USDA ARS, Applicat Technol Res Unit, Wooster, OH 44691 USA.

However the magnitude of this difference has not been well documented and is affected by various environmental factors. A study was performed to determine if the groundspeed changes due to load changes were sufficient to have a significant effect on the application rate of granular materials. An Air Tractor 402-B (turbine-powered), equipped with a SATLOC swath guidance system and an AutoCal Automatic Flow-Controller was used to collect the required data. Data logs from the SATLOC system provided height, groundspeed, and spray-time data; and AutoCal data files provided flow rate data from each spray run. Test protocols were developed to minimize effects of parameters other than load on groundspeed. The plane was loaded with 1040 L (275 gal) of water for each test to simulate the approximate weight of a fertilizer load. Results indicated that groundspeed increased approximately 64 km/h (4 mph) as a load changed from 8.9 to 1.8 kN (2000 to 400 lb). For a specific load, an increase of 2.8 degreesC (5 degreesF) in air temperature reduced groundspeed by approximately 0.8 km/h (0.5 mph). The effect of a specified load change on groundspeed increased as load was decreased. For a nominal groundspeed of 217 km/h (135 mph), these results show that speed change due to load change would be approximately 3% for the application of a full load of fertilizer A 3% reduction in nitrogen rate would be difficult to detect and would not be sufficient to cause color streaks across the field.

Chopped alfalfa or orchardgrass was placed in layers of 0.15, 0.30, and 0.45 m in a 482- x 584-mm rectangular container simulating the footprint of a tractor tire. Pressure between 20 and 80 kPa was applied to the forage by a platen. The total time of compaction varied between 2 and 10 s. A total of 23 tests (17 with alfalfa, 3 with grass, and 3 with mixed alfalfa-grass) were conducted; dry matter (DM) concentration ranged between 20% and 54%. The pre-compressed density of the first layer (0.30 in high) averaged 72 and 55 kg DM/m(3) for alfalfa and grass, respectively. The highest compressed density ranged between 138 and 339 kg DM/m(3) with an average of 220 kg DM/m(3). After releasing pressure, the relaxed density of the first, uppermost layer ranged between 81 and 152 kg DM/m(3) with an average of 127 kg DM/m(3). After six layers, the average relaxed density was 181 kg DM/m(3), 18% lower than the average highest compressed density. As successive layers were added, the cumulative DM density increased according to a logarithmic model. The model suggested that density would continually increase, slowly but without reaching a plateau, as the silo height increased. Within the experimental range, parameters of the logarithmic model were significantly affected by pressure, DM content, crop species and chop length, but not by layer thickness or time of compaction. More laboratory data are needed to understand interactions between the variables while field validation is necessary to extrapolate results to deep bunker silos.

The objective of this investigation was to characterize soil wetland processes related to nitrogen (N) treatment (nitrification-denitrification) and phosphorus (P) removal using soil oxidation-reduction potential (ORP) data. We evaluated three surface-flow wetland systems constructed for treatment of swine wastewater in Duplin Co., North Carolina, in 1992. Each system consisted of two 3.6- x 33.5-m cells connected in series. The three systems were planted to bulrushes, cattails, and agronomic crops (soybean in saturated soil culture and flooded rice), respectively. Soil aerobic/anaerobic conditions were determined by monitoring soil ORP at 18 sites using platinum (Pt) electrodes. Three monitoring sites were established in each wetland cell. Each site consisted of five Pt electrodes at three soil depths (0.02, 0.05, and 0.10 m) and a reference electrode. A data logger was used for hourly acquisition of soil ORP and temperature records. Hourly ORP data were averaged on a 24-h basis and corrected to standard hydrogen electrode readings (Eh). Frequency analysis of daily soil Eh showed that bulrush and soybean cells were moderately reduced (+100 < Eh < +300 mV) and anaerobic (Eh < +300 mV) about 70% of the time. However cattail and rice cells were anaerobic 100% of the time and had reduced (-100 < Eh < +100 mV) to highly reduced (Eh < -100 mV) soil conditions. These results indicate that different wetland plant species promote distinct anaerobic and reducing soil conditions. Outflow concentration of ammonia-N (NH3-N) and soluble P increased with increasing ORP values for bulrush and soybean-rice wetland cells due to lower temperatures during fall and winter but not for cattails. Denitrification enzyme activities and ORP indicated that soils in bulrush wetlands promoted better conditions for nitrification-denitrification than cattails or rice soils. However equivalent NH3-N removal rates (4.8-5.6 kg ha(-1) d(-1))for cattails and bulrush suggested that treatment occurred mostly in the water column for cattails rather than the wetland soil. Prevalent anaerobic soil conditions and soluble P outflow concentrations determined rather poor P retention capacity for all three wetlands.

Canopy temperature (TC) has been successfully used to time irrigation applications for well-watered crop growing conditions. The cumulative daily time that TC exceeds a crop-specific temperature threshold, designated as stress time (ST), is used to indicate the need for irrigation. Manipulation of the ST value required to indicate the need for irrigation changes irrigation frequency and seasonal irrigation. The ST value that generates the irrigation signal is the time threshold (TT). This study developed a procedure for estimating the relationship between TT for cotton and seasonal irrigation rates. Data were analyzed from irrigation studies that measured the water application and cotton yield response to a range of average daily ST All irrigation studies included a common control TT of 330 min/d above a canopy temperature threshold of 28degreesC as the criteria for the irrigation signal that maintained cotton in a well-watered status. In order to develop relationships between daily ST and final yield, or water input during the season, daily ST values were calculated and averaged over the irrigation season. The same procedure was used to calculate the average TC. The procedure for identifying control TT to establish different crop water status levels included the following steps. First, a linear relationship was defined between average daily ST and lint yield. Second, separate linear relationships were established between average daily ST and total water or irrigation input. Third, based on the slope of the trend line between average daily ST and yield, 1-h differences in average daily ST were selected to produce sufficiently large differences in total water and irrigation input to affect yield. These average ST values were 408, 468, and 528 min/d, and corresponded with control TT values of 330, 390, and 450 min/d. These control TT should result in different amounts of water application during the growing season and produce differences in cotton yield. C1 USDA ARS, Cropping Syst Res Lab, Lubbock, TX 79415 USA.

In this study, we isolated new microorganisms for depletion of inhibitors in lignocellulosic acid hydrolysates. A sequential enrichment strategy was used to isolate microorganisms from soil. Selection was carried out in a defined mineral medium containing a mixture of ferulic acid (5 mM), 5-hydroxymethylfurfural (5-HMF, 15 mM), and furfural (20 mM) as the carbon and energy sources, followed by an additional transfer into a corn stover hydrolysate (CSH) prepared using dilute acid. Subsequently, based on stable growth on these substrates, six isolates-including five bacteria related to Methylobacterium extorquens, Pseudomonas sp, Flavobacterium indologenes, Acinetobacter sp., Arthrobacter aurescens, and one fungus, Coniochaeta ligniaria-were chosen. All six isolates depleted toxic compounds from defined medium, but only C. ligniaria C8 (NRRL 30616) was effective at eliminating furfural and 5-HMF from CSH. C. ligniaria NRRL 30616 may be useful in developing a bioprocess for inhibitor abatement in the conversion of lignocellulosic biomass to fuels and chemicals.

Although overall the amount of trypsin synthesized in the larval gut was 2-fold higher than chymotrypsin, both enzymes are important in food digestion. Feeding Aeo-Trypsin Modulating Oostatic Factor (TMOF) to Ae. aegypti and Culex quinquefasciatus larvae inhibited trypsin biosynthesis in the larval gut, stunted larval growth and development, and caused mortality. Aea-TMOF induced mortality in Ae. aegypti, Cx. quinquefasciatus, Culex nigripalpus, Anopheles quadrimaculatus and Aedes taeniorhynchus larvae, indicating that many mosquito species have a TMOF-like hormone. The differences in potency of TMOF on different mosquito species suggest that analogues in other species are similar but may differ in amino acid sequence or are transported differently through the gut. Feeding of 29 different Aea-TMOF analogues to mosquito larvae indicated that full biological activity of the hormone is achieved with the tetrapeptide YDPA. Using cytoimmunochemical analysis, intrinsic TMOF was localized to ganglia of the central nervous system in larvae and male and female Ae. aegypti adults. The subesophogeal, thoracic, and abdominal ganglia of both larval and adult mosquitoes contained immunoreactive cells. Immunoreactive cells were absent in the corpus cardiacum of newly malted 4th instar larvae but were found in late 4th instar larvae. In both males and females, the intrinsic neurosecretory cells of the corpus cardiacum were filled with densely stained immunoreactive material. These results indicate that TMOF-immunoreactive material is synthesized in sugar-fed male and female adults and larvae by the central nervous system cells.

The distribution of these enzymes within fungal colonies and fungal cells is not clearly understood. The objective of this study was to investigate the distribution and subcellular location of Nor-1, Ver-1, and OmtA, which represent early, middle, and late enzymatic activities, respectively, in the aflatoxin biosynthetic pathway. The distribution of these three enzymes within A. parasiticus SU-1 was analyzed in time-fractionated, 72-h fungal colonies (fraction 1, 48-72 h; fraction 2, 24-48 h; fraction 3, 0-24 h). Western blot analysis and immunofluorescence microscopy demonstrated the highest abundance of Nor-1, Ver-1, and OmtA in colony fraction 2. Fungal tissues in this fraction were analyzed by immunoelectron microscopy. Nor-1 and Ver-1 were primarily localized to the cytoplasm, suggesting that they are cytosolic enzymes. OmtA was also detected in the cytoplasm. However, in cells located near the basal (substrate) surface of the colony, OmtA was predominantly detected in organelles tentatively identified as vacuoles. The role of this organelle in toxin biosynthesis is unclear. The relative distribution of OmtA to the cytoplasm or to vacuole-like organelles may depend on the age and/or physiological condition of the fungal cells.

Complete genome comparisons indicated that ONMV, currently classified as a rymovirus, was most closely related (similar to73% nucleotide, similar to79% amino acid identity) to the tritimovirus Wheat streak mosaic virus (WSMV). ONMV encoded a single polyprotein, with proteinase cleavage sites very similar to those of WSMV. Pairwise comparison of ONMV and WSMV cistrons revealed that P3 was most conserved (similar to79% nucleotide, similar to86% amino acid), whereas HC-Pro was most divergent (similar to67% nucleotide, similar to69% amino acid). In contrast, the ONMV sequence was distantly related (similar to40% nt, similar to26% amino acid identity) to that of the rymovirusRyegrass mosaic virus, with highest sequence conservation noted within the NIb cistron (similar to47% nucleotide, similar to41% amino acid identity). These results firmly establish that ONMV is not a rymovirus but is instead a distinct species of the genus Tritimovirus. C1 Univ Nebraska, USDA ARS, Lincoln, NE 68588 USA.

However, only five parasitoid species have been recorded for it. The parasitoid Celatoria bosqi Blanchard was the first parasitoid described from Diabrotica spp. in South America, where substantial parasitism has been observed. C bosqi has been collected almost throughout the South American distribution of its main host, Diabrotica speciosa (Germar), in an area that includes temperate and tropical lowlands, and semiarid to humid highlands. Three Diabrotica species were found to host the parasitoid, D. speciosa (Germar), Hystiopsis sp., and Diabrotica viridula (F.), with a total parasitism of 2.60, 5.55, and <0.02%, respectively. Laboratory experiments with field beetles and puparia, reared in the laboratory, indicate that C bosqi overwinters obligatorily in overwintering adult host beetles, remaining quiescent in its live host below developmental temperatures. Based on the known climatic range of C bosqi, and its requirement of adult overwintering hosts, a potential distribution in North America is projected. Published by Elsevier Inc.

The potential bioavailability of phenolic acids is controlled by sorption-desorption processes in soil. Sorption-desorption of p-coumaric acid (4-hydroxycinnamic acid), ferulic acid (3-methoxy-4-hydroxycinnamic acid), veratric acid (3,4-dimethoxybenzoic acid), vanillic acid (3-methoxy-4-hydroxybenzoic acid), and p-hydroxybenzoic acid (4-hydroxybenzoic acid) was characterized on soils with varying physicochemical properties. The phenolic acids sorbed quickly (<8 h) and in high proportions to the amount applied (average 84% of applied was sorbed). Sorption was irreversible with the batch desorption method used (0.01 N CaCl2 extraction). Pretreatment of soils to remove organic matter and free metal oxides from the soils decreased sorption, particularly in soils with free oxides removed. Statistical analysis suggested that sorption of p-coumaric and ferulic acids was correlated with soil clay content and veratric acid sorption was correlated with several soil factors. In contrast, no consistent relationship between soil characteristics and vanillic and p-hydroxybenzoic acid sorption was found. Based on the results of these experiments, i.e. the high reactivity of the phenolic acids, it is unlikely that these chemicals would be transported far from their point of origin, limiting their range of influence. It appears that, for phenolic acids to have allelopathic effects on plants, they would have to persist in the soil for long periods, resulting in a buildup of the chemical to high enough levels so that sufficient chemical would be in solution to cause the allelopathic effects, even though they may be strongly sorbed at lower concentrations.

Images revealed that pores in these gels were fluid and flattened out when measured as a function of time. These images revealed for the first time the structure of adsorbed sugar on pectin in the hydrated native gels and how the pectin framework is organized within these gels. Segmentation of images revealed that the underlying pectin framework contained combinations of rods, segmented rods, and kinked rods connected end to end and laterally. The open network of strands was similar to pectin aggregates from 5 mM NaCl solution imaged earlier by electron microscopy (Fishman et al., Arch. Biochem. Biophys. 1992, 294, 253). Area measurements revealed that the ratio of bound sugar to pectin was in excess of 100 to 1 (w/w). Furthermore, images indicated relatively small differences in the organization of native commercial citrus pectin, orange albedo pectin, and lime albedo pectin gels at optimal pH as determined in this study. The findings are consistent with earlier gel strength measurements of these gels. In addition, values of gel strength were consistent with values of molar mass and viscosity of the constituent pectins in that they increased in the same order. Finally, we demonstrated the advantage of simultaneous visualization of height and phase shift images for observing and quantitating the nanostructure of relatively soft gels which are fully hydrated with a buffer.

Corn fiber was hydrolyzed by dilute sulfuric acid and neutralized by one of two methods: conventional lime treatment or neutralization by strongly basic anion exchange. The anion exchange neutralized (AEN) hydrolysate contained substantially lower levels of the inhibiting compounds furfural, 5-hydroxymethylfurfural, and acetic acid compared to the lime neutralized hydrolysate. In batch fermentations the ethanol yields and final ethanol concentration of the two hydrolysates were similar at 0.32-0.43 g/g and 29-44 g/l, respectively. Sugar consumption in the AEN fermentations was superior. Coupling of a membrane pervaporation unit to a fed-batch fermentation of AEN hydrolysate maintained the ethanol concentration below 25 g/l with complete sugar utilization for approximately 5 days. A concentrated ethanol stream of 17 wt.% ethanol was produced by the pervaporation unit. Published by Elsevier Ltd. C1 USDA, Eastern Reg Res Ctr, Wyndmoor, PA 19038 USA.

The nozzles were operated at 276kPa pressure, 6(.)4kmh(-1) travel speed, and 0.5m above the top of canopies. The canopy leaf area index (LAI) and height were measured for each test and correlated with spray deposits at the bottom and middle of peanut canopies. Spray deposits at the top, middle and bottom of canopies were determined with a spray mixture containing water and a fluorescent tracer. The concentration of spray samples were corrected with the calibration of the photo degradation of the tracer exposed to direct sunlight, under artificial shade and in a dark room. Plants with single- and twin-row planting systems received significantly different spray deposits within peanut canopies. For all four nozzles during the growth season, the spray deposits decreased dramatically from the top to the bottom of canopies, and also tended to linearly decrease as LAI increased. Compared to the flat fan nozzle at the bottom of canopies at 75 days after planting, the air induction nozzle produced 2(.)6 times higher spray deposits for single-row plants and 1(.)6 times higher spray deposits for twin-row plants. During the three growth stages, the air induction nozzle produced the highest mean spray deposit at the bottom of canopies, followed by the twin jet and then hollow cone nozzles. The conventional flat fan nozzle had the lowest spray penetration performance among the four types of nozzles. Published by Elsevier Ltd on behalf of Silsoe Research Institute.

Soil-tyre interface pressures on the face of one lug and on an undertread region between two lugs were measured, and were used in estimating the tyre footprint area for the operating tyre. On the structured clay soil, the interface pressures on the I. g face were substantially greater than tyre inflation pressure and those on the undertread were considerably less than inflation pressure. On the loose sandy loam and the loose clay loam, some interface pressures on the lug face exceeded inflation pressure by only a small amount and others were a small amount less than inflation pressure, while undertread pressures were less than inflation pressure. Tyre footprint areas on the structured clay soil were nearly.,equal, for the three correctly inflated load and inflation pressure combinations.

Lactobacillus intermedius (NRRL B-3693), a heterofermentative lactic acid bacterium (LAB), was found to be an excellent producer of mannitol. The MDH from this bacterium was purified from the cell extract to homogeneity by DEAE Bio-Gel column chromatography, gel filtration on Bio-Gel A-0.5m gel, octyl-Sepharose hydrophobic interaction chromatography, and Bio-Gel Hydroxyapatite HTP column chromatography. The purified enzyme (specific activity, 331 U/mg protein) was a heterotetrameric protein with a native molecular weight (MW) of about 170 000 and subunit MWs of 43 000 and 34 500. The isoelectric point of the enzyme was at pH 4.7. Both subunits had the same N-terminal amino acid sequence. The optimum temperature for the reductive action of the purified MDH was at 35 degreesC with 44% activity at 50 degreesC and only 15% activity at 60 degreesC. The enzyme was optimally active at pH 5.5 with 50% activity at pH 6.5 and only 35% activity at pH 5.0 for reduction of fructose. The optimum pH for the oxidation of mannitol to fructose was 7.0. The purified enzyme was quite stable at pH 4.5-8.0 and temperature up to 35 degreesC. The K(m) and V(max) values of the enzyme for the reduction of fructose to mannitol were 20 mM and 396 mumol/min/mg protein, respectively. It did not have any reductive activity on glucose, xylose, and arabinose. The activity of the enzyme on fructose was 4.27 times greater with NADPH than NADH as cofactor. This is the first highly NADPH-dependent MDH (EC 1.1.1.138) from a LAB. Comparative properties of the enzyme with other microbial MDHs are presented.

Using monthly prices of pork and beef in 80 regions of Russia from 1994 to 1999, we measure the short-run response of regional prices to changes in foreign prices and domestic inflation. We find that changes in both foreign prices and domestic inflation have distinct impacts on the prices of these commodities in different Russian cities, indicating that the markets are segmented in the short run. An analysis of the effect of the financial crisis shows that the response to the crisis was mixed, with some regions showing more evidence of segmentation than others.

Analysis on EDS included crude protein (CP), in vitro organic matter degradability (IVOMD), and gas production profiles in N supplemented and unsupplemented incubation media. Brome-suppression tended (P = 0.07) to increase CP content but effects on gas production kinetics and IVOMD were dependent on incubation medium N-level. In N-unsupplemented incubations, asymptotic gas production was less and rates of gas production were greater in EDS from brome-suppressed compared to undisturbed pasture. No such differences were found for N-supplemented incubations. Weight gains of steers grazing brome-suppressed pastures were 16% greater (P = 0.007) than from control pastures. The R(2) for the comparison of predicted and measured gains were 0.90 (P < 0.0001), 0.96 (P < 0.0001), and 0.90 (P < 0.0001) using CP, IVOMD (N-low), and IVOMD (N-rich) as the predicting variable, respectively. Best predictions using in vitro gas production measurements were obtained from 24 h gas volume recording (R(2) = 0.93, P < 0.0001). Best-fit model (sigmoidal vs. exponential) depended on grazing period and N-level, and the sigmoidal Gompertz model best described most gas production profiles.

In the models, cell death is caused by irreversible damage to cellular molecules that occurs at rates that increase exponentially with temperature. The models differ in whether cells show cumulative effects of heating. The temperature dependencies of the models' rate parameters were estimated from cell-count data after exposing live-bark tissues from four Canadian Rocky Mountain tree species to a range of fixed temperatures in a water bath. Based on both models, lodgepole pine's (Pinus contorta Dougl. ex Loud.) growing season vascular cambium cells experienced lower mortality rates at elevated temperatures than those of aspen (Populus tremuloides Michx.), Engelmann spruce (Picea engelmannii Parry ex Engelm.), and Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). Growing and dormant season differences were marginal. With reservations for lodgepole pine, both models predicted cell survival after exposures to rising and falling temperatures such as would be experienced by live tissues during fires. A simulation involving conduction heat transfer from flames and vascular cambium cell mortality suggests that differences among species in thermal tolerance are small compared with the effects of bark thickness. Although stem vascular cambium cell mortality was complete when tissues reached 60degreesC during simulated surface fires, it may not be warranted to apply the 60degreesC threshold to other tissues exposed to contrasting temperature regimes during fires.

Each forest site comprised three contiguous watershed-scale treatment units: one burned in 1996 and 1999, one burned annually from 1996 through 1999, and an unburned control. Soil organic matter, available P, net N mineralization, and nitrification were not significantly changed by fire at either frequency, though values for the latter two properties increased 4- to 10-fold from the period 1995-1997 to the period 1999-2000. Fire at both frequencies resulted in increased soil pH and exchangeable Ca(2+). Exchangeable Al(3+) was reduced by fire at two of four sites, and the molar ratio of Ca/Al was increased by fire at three of four sites. In contrast to results in most studies of fire, N transformations and availability were not increased by fire in this N-enriched region (deposition of N averaged about 6 kg.ha(-1).year(-1) over the last 20 years). We hypothesize that the large observed increase in nitrification is an indication of the onset of N saturation. Although fire appears to offset the effect of atmospheric deposition in this region by increasing soil pH, Ca(2+), and Ca/Al ratio and reducing available Al(3+), increased NO(3)(-) fluxes through the soil from continued N deposition may negate the positive effect of fire.

It is performed to increase the credibility and gain sufficient confidence about a model. This paper evaluated the usefulness of 10 statistical tests, five parametric and five nonparametric, in validating forest biometric models. The five parametric tests are the paired t test, the (2)(X) test, the separate t test, the simultaneous F test, and the novel test. The five nonparametric tests are the Brown-Mood test, the Kolmogorov-Smirnov test, the modified Kolmogorov-Smirnov test, the sign test, and the Wilcoxon signed-rank test. Nine benchmark data sets were selected to evaluate the behavior of these tests in model validation; three were collected from Alberta and six were published elsewhere. It was shown that the usefulness of statistical tests in model validation is very limited. None of the tests seems to be generic enough to work well across a wide range of models and data. Each model passed one or more tests, but not all of them. Because of this, caution should be exercised when choosing a statistical test or several tests together to try to validate a model. It is important to reduce and remove any potential personal bias in selecting a favorite test, which can influence the outcome of the results.

Three products were evaluated in combination with two methods that promoted attack of trees by D. frontalis. One method used attractive semiochemicals and the other decreased host resistance, both of which are important scenarios for implementing protective treatments of individual trees. Each method promoted mass attack of unprotected control trees, thus providing a statistically verifiable challenge to the candidate protectants. In trees with increased susceptibility, mortality ranged from 63% (untreated) to 77% (4AA applied in paintball formulation), and two products appeared to alter the relative composition of scolytid species that attacked at two heights; however, tree mortality was unaffected. In trees challenged with semiochemical attractants, mortality ranged from 54% (4AA released from vials) to 82% (untreated and paintball application of 4AA). Although 4AA consistently reduces catch of D. frontalis in traps, it was not efficacious for protecting individual loblolly pines over a period of 30 or 60 days in this experiment.

Aspergillus isolates were obtained from various Mississippi Delta crops (corn, peanut, rice, cotton) and soils. Most of the isolates (99%) were A. flavus and the remainder comprised A. parasiticus and A. nomius. The following three cultural methods were evaluated on potato dextrose agar: fluorescence (FL) on beta-cyclodextrin-containing media (CD), yellow pigment (YP) formation in mycelium and medium, and color change after ammonium hydroxide vapor exposure (AV). Aflatoxins in culture extracts were confirmed by thin-layer chromatography (TLC) and quantified by enzyme-linked immunosorbent assay (ELISA). Of the 517 isolates, 314 produced greater than 20 ng/g of total aflatoxin based on ELISA, and 180 produced greater than 10 000 ng/g of aflatoxin in the medium. Almost all the toxigenic isolates (97%) were confirmed by TLC as producers. Of the toxigenic isolates, as determined by ELISA, 93%, 73%, and 70% gave positive FL, YP, and AV responses, respectively. Of the 203 isolates producing less than 20 ng/g of aflatoxin, 20%, 6%, and 0% of respective FL, YP, and AV methods gave false-positive responses. The 9% false-positive results from TLC fall within this range. This study showed good agreement among all tested cultural methods. However, these cultural techniques did not detect aflatoxin in all cultures that were found to produce aflatoxins by ELISA, LC/MS, and TLC. The best results were obtained when the AV color change and CD fluorescence methods were used together, yielding an overall success rate comparable to TLC but without the need for chemical extraction and the time and expense of TLC.

In 199 hours of observation at 5 fruiting colonies in the Delta National Forest, Sharkey County, Mississippi, we recorded 82 bird species in the vicinity of a colony. Of these, 12 were observed on pondberry plants, and two consumed ripe pondberry fruits. Of these, the northern cardinal, Cardinalis cardinalis (Cardinalidae), was a seed predator. The other, hermit thrush, Catharus guttatus (Turdidae), was a dispersal agent for the plants. Numbers of fruits declined rapidly after hermit thrushes arrived in October and no fruits remained by January. Winter behavior of hermit thrushes constrains their dispersal of seeds to short distances. Without establishment of additional colonies, pondberry dispersal by birds to unoccupied patches of suitable forest is unlikely.

Within a given model, all monosaccharide units and their linkages are identical so the models are regular helices. Despite fairly large ranges for the glycosidic linkage torsion angles phi and psi, 29degrees and 57degrees, respectively, there is little variation in the n and h parameters of the model helices. They are extended, with h values (the advance per residue along the helix axis) of 5.04-5.27 Angstrom. Some models were slightly right-handed, with n values up to 2.12 residues per helix turn. Left-handed models were in the majority, and their n values were as large as -2.91. These results are consistent with known structures of cellulose and its derivatives. An exception comes from a heavily derivatized cellobiose molecule. It yields right-handed helices with n approximate to 4.5 and h approximate to 3 Angstrom. Because one half turn of this helix reverses the direction of the chain in a compact region, the linkage geometry is a model for chain-folding. Other derivatives that are unable to form the O3...O5' hydrogen bond gave left-handed helices. The puckering of the glucose rings was also surveyed. A number of rings in small molecule structures are puckered to a degree that is similar to the puckering determined for methyl cellotrioside, cellotetraose, cellulose Ibeta and cellulose II.

In this study, differences in the texture and flavor of 17 diverse cultivars related to genetic differences were characterized and the stability of their flavor and texture from one crop year to the next was determined. Sensory attributes of cooked rice were measured by panelists using descriptive sensory analysis methodology. Cooked texture of the cultivars varied widely and correlated well with amylose content with con-elation coefficient (r) values in the range 0.76-0.97 for I I of the 14 attributes. Flavor attribute intensities were low and similar among cultivars, with the exception of grain flavor. Grain flavor ranged in intensity from 2.2 to 4.9 and correlated highly and negatively with amylose content (-0.88). Roughness and hardness were the only textural attributes which were significantly different (P < 0.05) in the crop year 2 cultivar set compared to the crop year I set with the higher values of these two attributes in crop year 2 being explained primarily by protein contents being approximate to3% higher. Hay-like, sweet aromatic, sour, and astringent were the only flavor attributes which were significantly (P < 0.05) different between the crop year sets. Ward's Cluster Analysis grouped the cultivars into five clusters with cultivars belonging to each cluster having common texture and flavor characteristics. Changes in assignment to clusters from one crop year to the next allowed assessment of the stabilities of the sensory impact of the cultivars to environmental factors.

Identification of wheat color is not straightforward, and currently there is interest in characterizing red and white wheats using spectroscopic methods and chemical tests. The kernels of both red and white wheats exhibit natural fluorescence that can be readily viewed under UV light, although it is not possible to differentiate the fluorescence spectra of red and white wheats by visual inspection only. Fluorescence emission spectra in the wavelength range of 370670 nm for 91 wheat samples consisting of 48 red (from 30 cultivars) and 43 white (from 18 cultivars) were analyzed by partial least squares (PLS) and neural networks analyses (NNA). Samples included cultivars that were difficult to classify visually as well as wheat harvested after rainfall. Classification accuracies were approximate to85% for calibration and approximate to72% for the validation samples by both analyses. A plot of beta-coefficient vs. wavelength in PLS analysis indicated that fluorescence of red wheat cultivars was greater than that for white wheat cultivars at 425 (+/-20) nm wavelength. Fluorescence of white wheat cultivars was greater than that for red cultivars at 587 (+/-35) nm. Fluorescence emission at approximate to450 nm from wheat samples increased in intensity after treatment with NaOH. The increase was greater for red than for white wheat. Wheat harvested after rainfall also exhibited a slight increase in fluorescence. C1 USDA ARS, Engn Res Unit, Grain Marketing & Prod Res Ctr, Manhattan, KS 66502 USA.

Bread staling was mainly due to amylopectin retrogradation. NIRS measured amylopectin retrogradation accurately in different batches. Three important wavelengths, 970 nm, 1,155 nm, and 1,395 nm, were associated with amylopectin retrogradation. NIRS followed moisture and starch structure changes when amylopectin retrograded. The amylose-lipid complex changed little from one day after baking. The capability of NIRS to measure changes in the retrograded amylose-lipid complex was limited. Two important wavelengths, 550 nm and 1,465 nm, were key for NIRS to successfully classify the starch-starch (SS) and starch-protein (SP) bread based on different colors and protein contents in SS and SP. Low temperature dramatically accelerated the amylopectin retrogradation process. Protein retarded bread staling, but not as much as temperature. The starch and protein interaction was less important than the starch retrogradation. Protein hindered the bread staling process mainly by diluting starch and retarding starch retrogradation.

Tissue disposition, excretion and metabolism was determined. BTBPE is a low-volume brominated flame retardant used in resins or plastics, and toxicity data in peer-reviewed journals is extremely limited. BTBPE was fairly insoluble in lipophilic solutions, which made dose preparation difficult. The great majority of C-14 (>94%) was excreted in the feces of both groups of rats at 72 h, and tissue retention was minimal. Lipophilic tissues contained the highest concentrations of BTBPE, e.g. thymus, adipose tissue, adrenals, lung, and skin. Metabolites were excreted in the urine, bile and feces, but at a very low level. Fecal metabolites were characterized as monohydroxylated, monohydroxylated with debromination, dihydroxylated/debrominated on a single aromatic ring, monohydroxylated on each aromatic ring with accompanying debromination, and cleavage on either side of the ether linkage to yield tribromophenol and tribromophenoxyethanol. Despite a limited quantity of stable metabolites extractable in the feces, non-extractable C-14 levels were relatively high (39% of the 0-24 h fecal C-14), which suggested that BTBPE could be metabolically activated in the rat and covalently bound to fecal proteins and/or lipids. It was concluded that limited absorption and metabolism of BTBPE would occur by ingestion in mammals. (C) 2003 Elsevier Ltd. All rights reserved. C1 USDA ARS, Biosci Res Lab, Fargo, ND 58105 USA.

Bacterial artificial chromosomes (BACs) contain large inserts making them amenable for FISH mapping. We used BAC-FISH to study genome organization and evolution in hexaploid wheat and its relatives. We selected 56 restriction fragment length polymorphism (RFLP) locus-specific BAC clones from libraries of Aegilops tauschii (the D-genome donor of hexaploid wheat) and A-genome diploid Triticum monococcum. Different types of repetitive sequences were identified using BAC-FISH. Two BAC clones gave FISH patterns similar to the repetitive DNA family pSc119; one BAC clone gave a FISH pattern similar to the repetitive DNA family pAs1. In addition, we identified several novel classes of repetitive sequences: one BAC clone hybridized to the centromeric regions of wheat and other cereal species, except rice; one BAC clone hybridized to all subtelomeric chromosome regions in wheat, rye, barley and oat; one BAC clone contained a localized tandem repeat and hybridized to five D-genome chromosome pairs in wheat; and four BAC clones hybridized only to a proximal region in the long arm of chromosome 4A of hexaploid wheat. These repeats are valuable markers for defined chromosome regions and can also be used for chromosome identification. Sequencing results revealed that all these repeats are transposable elements (TEs), indicating the important role of TEs, especially retrotransposons, in genome evolution of wheat.

The first stage ranks mean annual flow rates during 1939-1998, calculates Mann-Whitney U statistics from samples of those rankings over running time windows, and then tests those U statistics for significance. This analysis of the records of 42 Hydro-Climatic Data Network stations over the Great Plains and Midwest reveals consistent patterns of highly ranked annual streamflow during time windows at the end of the century, with most beginning during the late 1960s and early 1970s and ending in either 1997 or 1998. Many of these stations are located in a critical agricultural region known as the Corn Belt. The second stage of analysis compares both the duration of abnormal flow periods and the frequency of hydrological surplus and drought conditions during the high flow years indicated by the first stage, relative to the remaining years of 1939-1998. Among gage stations in the climatologically drier western Corn Belt during the 1980s and 1990s there is a clear tendency toward extended periods of above normal flow, which results in more than a doubling in the average annual frequency of hydrological surplus days relative to previous years. These stations also show more than a 50% reduction in the average annual frequency of hydrological drought days relative to previous years. Similar but less pronounced shifts in hydrological regime are evident in the central and eastern Corn Belt, and in the Mississippi River at Vicksburg during 1973-1998. These results indicate that many areas of the central United States have shifted toward a climate regime of relative hydrological surplus during the closing decades of the 20th century.

There are three types of aMPV, of which type C is found only in the United States. The aMPV nucleoprotein (N) amino acid sequences of serotypes A, B, and C were aligned for comparative analysis. On the basis of the predicted antigenicity of consensus sequences, five aMPV-specific N peptides were synthesized for development of a peptide antigen enzyme-linked immunosorbent assay (aMPV N peptide-based ELISA) to detect aMPV-specific antibodies among turkeys. Sera from naturally and experimentally infected turkeys were used to demonstrate the presence of antibodies reactive to the chemically synthesized aMPV N peptides. Subsequently, aMPV N peptide 1, which had the sequence 10-DLSYKHAILKESQYTIKRDV-29, with variations at only three amino acids among aMPV serotypes, was evaluated as a universal aMPV ELISA antigen. Data obtained with the peptide-based ELISA correlated positively with total aMPV viral antigen-based ELISAs, and the peptide ELISA provided higher optical density readings. The results indicated that aMPV N peptide 1 can be used as a universal ELISA antigen to detect antibodies for all aMPV serotypes. C1 USDA ARS, SE Poultry Res Lab, Athens, GA 30605 USA.

Variation in CFE was assessed under different culture conditions. The conditions examined were ambient atmosphere (similar to20% oxygen) culture versus 5% oxygen culture, three levels of fetal bovine serum (FBS) in the medium (5%, 10% or 20%), and the amendment of 10% FBS medium with basic fibroblast growth factor (1 ng/mL), L-carnosine (20 mM), or hydrocortisone (1 muM). The six BFF cell lines showed significant differences from one another in CFE. No significant difference in CFE was found with reduced oxygen culture. L-Carnosine also had no significant effect on CFE. A FBS concentration of 10% was found to produce the best overall CFE. Hydrocortisone treatment reduced the size of colonies although the number of colonies formed was not affected. Basic FGF increased the size of colonies but the number of colonies formed was not affected. The results showed that different BFF cell lines varied significantly in their CFE. Also, some medium supplements or culture conditions that have shown positive CFE effects on the fibroblasts of other species failed to show significant positive CFE effects on the BFF cell lines tested.

AB Hop (Humulus lupulus L.) is an important cash crop in the U.S. Pacific Northwest. Classifying groups of hop accessions presently held in the USDA-ARS world collection is vital toward categorizing newly imported accessions and identifying closely related (if not identical) cultivars. The objective of this study was to identify hop germplasm diversity pools on the basis on morphological and chemical data by cluster analysis. Eight hop quality characteristics including yield (YLD), alpha acids, beta acids, hop-storage index (HSI), colmmulone (CoH), myreene (M), caryophyllene (C), and humulene (H) were obtained from historical databases for 129 accessions from the USDA-ARS hop germplasm field collection located near Corvallis, OR. Three distinct genetic diversity pools were identified and named: (i) European, (ii) Wild North American, and (iii) Hybrids. The European pool was divided into English and Continental European subgroups distinguished by their a-acids and CoH contents. The Hybrid pool was divided into five subgroups distinguished by their geographic origins. The variables YLD and CoH content differentiated these five subgroups (r = 0.92; P less than or equal to 0.05). The information presented in our study will help categorize newly imported accessions into the current U.S. hop germplasm collection and will help in identifying closely related or similar accessions.

A wheat (Triticum aestivum L.) mutant is described herein with greatly reduced seed phytic acid P but little change in seed total P, similar to lpa1-type mutants described in other grain species. One nonlethal mutant from 562 ethyl-methanesulfonate (EMS) mutagenized M-2 lines was identified with a high inorganic phosphate (HIP) phenotype and designated Js-12-LPA. Js-12-LPA homozygotes produced seed in which phytic acid P represented 48.2% of seed total P, in contrast to 74.7% of seed total P in nonmutant or wild-type control, Js-12-WT. The inorganic portion of seed P was increased from 9.1% in Js-12-WT to 50.1% in Js-12-LPA, with little effect on total seed P. Weight distributions among milling fractions were similar for the Js-12-LPA and Js-12-WT genotypes. The low phytic acid trait altered the distribution of total P within the kernel, increasing the P content of the central endosperm and decreasing the P content of the bran. The low phytic acid trait decreased the phytic acid concentration in the bran by 43% and increased the inorganic P concentration in the bran nearly four-fold. Inheritance data of F-2 and F-4:6 families was inconsistent with a single-gene mutation and suggests the involvement of two or more genes. This low phytic acid wheat mutant is a genetic resource for studying the biology of seed phytic acid metabolism and wheat quality improvement.

The relative abundance of ureides (RAU) in plant tissues has been used for estimating N-2 fixation in soybean [Glycine max (L.) Merr.] grown under well-watered conditions, but it has not been evaluated for drought conditions. The present research evaluated the response of N accumulation to N fertilization, the ability of the RAU technique to predict N-2 fixation under drought conditions, and the response of yield to N fertilization under well-watered and drought conditions. Under drought, shoot N accumulation rate during vegetative growth approximately doubled as the amount of N fertilizer was increased from 10 to 200 kg N ha(-1), indicating a greater sensitivity of N-2 fixation to drought than uptake and assimilation of inorganic N. Under well-watered conditions, the relationship between estimates of N-2 fixation made by N-15-dilution and RAU agreed within 15% of published reports. Under drought conditions, however, this relationship was greatly different (13 to 43%) from published reports. Fertilization with inorganic N in 1 yr increased grain yield 15 to 25% for the drought treatment and 12 to 15% for the well-watered treatment. In a second year, N fertilization increased yield of both drought and well-watered treatments approximately 9%. This research indicates that the RAU technique for estimating N-2 fixation under drought conditions may be invalid without further refinement, that N-2 fixation is more sensitive to drought than the uptake and assimilation of inorganic soil N, and that increasing the tolerance of N-2 fixation to drought would likely result in yield increases.

MacMill. ex B.L. Rob. & Fernald]. Our objective was to estimate N2 fixation of three Illinois bundleflower accessions managed for forage. Herbage yield ranged from 1.02 Mg ha(-1) to 3.69 Mg ha(-1) in Year 1, and 2.99 Mg ha(-1) to 8.27 Mg ha(-1) in Year 2. Accessions differed in herbage yield, aboveground N yield, and N-2 fixed at certain locations in Year 1, but not in Year 2. Percentage of N derived from the atmosphere (%Ndfa) varied with location but not with accession in either year. The IN natural abundance method gave lower estimates of %Ndfa than the N-15 enrichment method. In yr 1, N-2 fixation ranged from 0 to 30 kg ha-(1) N (N-15 natural abundance method), 11 to 43 kg ha(-1)(N-15 enrichment method), and 0 to 50 kg ha(-1) N (total N difference method), and in Year 2 these estimates at two locations were 60 to 67 kg ha(-1) N, 79 to 127 kg ha(-1) N,and 67 to 142 kg ha(-1) N, respectively. Differences in N-2 fixation among locations could have been due to rhizobial strains. At the high-yielding location with the greatest N-2 fixation, over one-half of the nodules were occupied by indigenous rhizobial strains, whereas at other locations, strains from commercial inoculant accounted for most nodules. Symbiotic N-2 fixation by Illinois bundleflower could be enhanced by new rhizobial inoculums. C1 Univ Minnesota, Dept Agron & Plant Genet, St Paul, MN 55108 USA.

Objectives of this study were to determine if seedlings from big bluestem (Andropogon gerardii Vitman) and switchgrass (Panicum virgatum L.) populations that differ genetically in seedling tiller number differ in mature plant (i) morphological characteristics, (ii) forage yield managed by a three-cut harvest system or a single end-of-season harvest, and (iii) leaf elongation rate. Field experiments were conducted on a Kennebec silt loam soil (fine-silty, mixed, superactive, mesic Cumulic Hapludolls). In addition, greenhouse studies were conducted in 1999 through 2001. Seedlings from big bluestem and switchgrass populations that differed for seedling tiller numbers were transplanted into spaced-planted field nurseries and greenhouse pots for study. Leaf width, leaf length, plant height, number of tillers per plant, yield, and leaf elongation rate were measured. Mature plant morphological characteristics differed between multiple-tiller and single-tiller plant types for both big bluestem and switchgrass. There were no differences in forage yield for big bluestem plant types. Switchgrass single-tiller plant types yielded 200 g plant(-1) more than multiple-tiller types when harvested only once. Leaf elongation rate was 22 and 28% greater for single-tiller types vs. multiple-tiller types for big bluestem and switchgrass, respectively. Selection at the seedling level for tiller number appears to be an effective method to develop genotypes differing in yield per tiller, which has been shown to affect herbage yield when grown in swards.

Our objective was to evaluate forage production of sainfoin (Onobrychis viciifolia Scop.), a nonbloating legume, compared with alfalfa (Medicago sativa L.). Thirteen sainfoin cultivars and 'Deseret' alfalfa were evaluated at four water levels (WLs) and four harvests in 1998 and 1999 under a line-source irrigation system. Water levels (WL1, WL2, WL3, and WL4) received an average of 78.3, 65.81 34.91 and 8.3 cm of water, respectively. Significant effects were found for cultivar, cultivar x WL, harvest date, and cultivar x harvest date. Annual production of sainfoin at WL1 WL2, WL3, and WL4 was 11.6, 11.4, 9.6, and 8.9 Mg ha(-1), respectively, whereas annual production of Deseret was 20.7, 18.5, 18.0, and 16.3 Mg ha(-1) respectively. Overall yield trends across WLs were linear for sainfoin and Deseret and were parallel (P = 0.55) with slopes of b = 0.042 and b = 0.054, respectively. Yield of sainfoin at Harvest I through 4 was 5.5, 2.1, 1.5, and 1.3 Mg ha(-1), respectively. Yield of Deseret from Harvest 1 through 4 was 5.9, 5.3, 4.7, and 2.4 Mg ha(-1), respectively. Yields of the two species at Harvest 1 did not differ. The flat linear trend across WLs verifies that both crops are tolerant to dry conditions. With its highest production potential during early growth, sainfoin is best suited for situations where early growth of a nonbloating legume is desired, but will not compete with alfalfa in total seasonal production.

The objective of this study was to assess GD on the basis of isozymes in 15 wild red clover (Trifolium pratense L.) populations collected in the Caucasus Mountains, Russia. Isozymes assayed were esterase, beta-glucosidase, phosphoglucomutase, peroxidase, diaphorase, phosphoglucoisomerase, and superoxide dismutase. Ten isozyme loci with 26 alleles were detected. Ninety percent of the loci were polymorpkic in at least one population. Percent polymorphic loci within populations ranged between 50 and 90%. At the species level, the number of alleles per polymorphic locus was 2.89 and effective number of alleles per locus was 1.84. Within-population averages were 2.75 and 1.70, respectively. Genetic diversity was 0.353 at the species level and the mean value for the populations was 0.323. Some of the populations such as PI 604728 and PI 604735 were unique at the at the isozyme level. The other 13 accessions could be consolidated into one accession. Diversity measurements indicated that this species has a high level of variability that resides mostly within populations. Gene flow expectations based on predictions using topographic maps developed using interpolated digital and climatic surfaces coincided with gene flow estimates obtained using isozymes. This supports the use of GIS tools and remotely sensed data to develop maps that help germplasm collection and post-collection efforts to understand patterns of GD in collected germplasm.

Merr.], but only two categories of leaflet shape are routinely used to characterize soybean germplasm. Very little information has been published about leaflet shape and size for wild soybean (Glycine soja Sieb. & Zucc.) accessions in the USDA Soybean Germplasm Collection but these characteristics have been shown to be among the most diverse morphological traits in the Chinese G. soja collection. The objectives of this research are to evaluate and establish a visual classification system for the variation of leaflet shape and size in the USDA Soybean Germplasm Collection. In 1998 and 1999, 661 wild soybean accessions from the USDA Soybean Germplasm Collection in maturity groups 000 through IX were grown at either Urbana, IL, or Stoneville, MS. Images of fully expanded terminal leaflets were recorded with a digital camera after all accessions were in the reproductive phase. Representative leaflets were selected at approximately two-thirds of the distance from the ground to the top of the plant. Images were analyzed by the computer software Image-Pro Plus (Version 3.0). Six measured or calculated parameters were recorded. The FASTCLUS procedure of SAS was used to define appropriate categories of leaflet shape and size. Length/width ratio and length were chosen to define leaflet shape and leaflet size, respectively. Length/width ratio values ranged from 1.3 to 6.2 and length from 3 to 14 cm. Five categories of leaflet shape are proposed: oval, ovate, lanceolate, linear, and ultra linear; and three classes for leaflet size: small, intermediate, and large. Leaflet shape and leaflet size are associated with geographical origin. Accessions from South Korea were generally smaller than those from China, Japan, and Russia. Accessions from China had more leaflet variation than those from South Korea or Japan but those from Russia were the most variable. Nearly all of the accessions with lanceolate and linear leaflets originated from Russia. C1 Univ Illinois, Dep Crop Sci, Urbana, IL 61801 USA.

Reducing water contents from 1.7 and 0.26 gH(2)O g(-1) dry mass (g g(-1)) is believed to increase cytoplasmic viscosity. Cooling to -196degreesC was done at rates averaging between 0.17 and 1300degreesC s(-1), and warming at 600 or 1.35degreesC s(-1). Survival was assessed after 4 weeks in vitro. Rapid warming resulted in higher survival and normal development of axes at all water contents. The effects of cooling rate were dependent on the water content of axes. Cooling rates resulting in >70% normal development ranged between 0.17 and about 1300degreesC s(-1) for axes at a water content of 0.26 g g(-1), narrowing with increasing hydration to an apparent optimum at about 686degreesC s(-1) in axes at 0.8 g g(-1). At 1.7 g g(-1), axes cooled at 0.17degreesC s(-1) yielded nearly 40% normal development, whereas faster cooling was deleterious. Results are interpreted in the context of the effect of water content on cytoplasmic viscosity and the rate of intracellular ice formation. At low water contents, the high intracellular viscosity slows ice crystallization making survival independent of cooling rate. At higher water contents, the reduced viscosity requires faster cooling to prevent ice crystal damage. The ability to cool rapidly with increasing hydration is balanced with an increasing limitation to dissipate heat fast enough to prevent severe damage.

Competition for nutrients and space is believed to be the major mode of action. Involvement of fungal cell wall-degrading enzymes is also suggested to play a role in the mechanism of action of yeast antagonists. The present study showed that the yeast C. oleophila is capable of producing and secreting various cell wall-degrading enzymes, including exo-beta-1,3-glucanase, chitinase and protease. Exo-beta-1,3-glucanase and chitinase were produced and maximized in the early stages of growth, whereas protease reached a maximum level only after 6-8 days. Production of exo-beta-1,3-glucanase, chitinase and protease was stimulated by the presence of cell wall fragments of Penicillium digitatum in the growth medium, in addition to glucose. This study also provided evidence that C. oleophila is capable of secreting exo-beta-1,3-glucanase into the wounded surface of grapefruit. The role of exo-beta-1,3-glucanase (CoEXG1) in the biocontrol activity of C. oleophila was tested using CoEXG1-knockouts and double-CoEXG1 over-producing transformants. In vitro bioassays showed that wild-type C. oleophila and exo-beta-1,3-glucanase over-expressing transformants had similar inhibitory effects on spore germination and germ-tube elongation; and both were more inhibitory to the fungus than the knockout transformant. In experiments conducted on fruit to test the biocontrol activity against infection by P. digitatum, no significant difference in inhibition was observed between transformants and untransformed C. oleophila cells at the high concentrations of cells used, whereas at a lower concentration of yeast cells the knockout transformants appeared to be less effective.

Here, we describe the Tri15 gene, which represents a fourth locus involved in trichothecene biosynthesis. Tri15 is predicted to encode a Cys(2)-His(2) zinc finger protein and is expressed in a manner similar to genes in the core trichothecene gene cluster. However, disruption of F. sporotrichioides Tri15 does not affect production of T-2 toxin, the major trichothecene produced by this fungus. This result suggests that Tri15 is not necessary for the production of toxin. Cultures with exogenously added T-2 toxin have high levels of Tri15 expression and no detectable expression of the trichothecene biosynthetic genes Tri5 and Tri6. The expression analysis is consistent with Tri15 being a negative regulator of at least some of the trichothecene biosynthetic genes. In F. graminearum, Tri15 has been mapped to linkage group 2 and is therefore unlinked to the main trichothecene biosynthetic gene cluster.

If ammonia was limiting and either cellobiose or glucose was in excess, the viability declined even faster. The carbohydrate-excess, ammonia-limited cultures did not spill energy, but they accumulated large amounts of cellular polysaccharide. Cultures that were carbohydrate-limited had approximately 4 nmol ATP mg cell protein(-1), but ATP could not be detected in cultures that had an excess of soluble carbohydrates. However, if F. succinogenes A3C was provided with excess cellulose and ammonia was limiting, ATP did not decline, and the cultures digested the cellulose soon after additional nitrogen sources were added. From these results, it appears that excess soluble carbohydrates can promote the death of F. succinogenes, but cellulose does not. C1 Cornell Univ, Microbiol Sect, Ithaca, NY 14853 USA.

Introduced within the past decade, this methodology allows detection of the expression of thousands of genes simultaneously and, hence, is a potentially powerful tool for studying the regulation of physiological mechanisms that are triggered or inhibited by nutrients. Recent findings Recent data generated with cDNA microarrays not only confirm the effects of n-3 polyunsaturated fatty acids on regulation of lipolytic and lipogenic gene expression as determined by more traditional methods but also emphasize the tissue specificity of this regulation. cDNA microarray experiments also have expanded our understanding of the role of n-3 polyunsaturated fatty acids in regulation of expression of genes involved in many other pathways. These include: oxidative stress response and antioxidant capacity; cell proliferation; cell growth and apoptosis; cell signaling and cell transduction. Summary The cDNA microarray studies published to date show clearly that n-3 polyunsaturated fatty acids, usually provided as fish oil, modulate expression of a number of genes with such broad functions as DNA binding, transcriptional regulation, transport, cell adhesion, cell proliferation, and membrane localization. These effects, in turn, may significantly modify cell function, development and/or maturation. C1 McNeil Nutrit, Brunswick, NJ USA.

Beginning, in 1997 nine experimental plots were established: three open-top chambers with ambient CO2 levels (approximately 365 mumol mol(-1)), three open-top chambers with twice-ambient CO2 levels (approximately 720 mumol mol(-1)), and three unchambered control plots. After 3 years of growing-season CO2 treatment, the aboveground N concentration of plants grown under elevated atmospheric CO2 decreased, and the carbon-nitrogen (C:N) ratio increased. At the same time, increased aboveground biomass production under elevated atmospheric CO2 conditions increased the net transfer of N out of the soil of elevated-CO2 Plots. Aboveground biomass production after simulated herbivory was also greater under elevated CO2 compared to ambient CO2. Surprisingly, no significant changes in belowground plant tissue N content were detected in response to elevated CO2. Measurements of individual species at peak standing phytomass showed significant effects of CO2 treatment on aboveground plant tissue N concentration and significant differences between species in N concentration, suggesting that changes in species composition Under elevated CO2 will contribute to overall changes in nutrient cycling. Changes in plant N content, driven by changes in aboveground plant N concentration, could have important consequences for biogeochemical cycling rates and the long-term productivity of the shortgrass steppe as atmospheric CO2 concentrations increase.

To address this need, a group of social, earth, and life scientists associated with the National Science Foundation's (NSF) Long-Term Ecological Research (LTER) Network have articulated a conceptual framework for understanding the human dimensions of ecological change for the LTER Network. This framework explicitly advocates that what is often divided into "natural" and human systems be considered a single, complex social-ecological system (SES). In this paper, we propose a list of core social science research areas, concepts, and questions; identify the need for multiscale investigatory frameworks crucial for implementing integrated research; and suggest practical approaches for integration. In sum, this paper is a general outline for empirical and cross-site research projects where investigators agree that bringing together social, biological, and earth scientists can lead to synthetic approaches and a unified understanding of the mechanisms regulating SES. Although the motivation for this goal is specific to the LTER Network and similar projects, we believe that the issues and ideas presented here are widely applicable to other interdisciplinary SES studies.

We focus mainly on ethnic variation in environmental belief, as measured by the New Ecological Paradigm (NEP), and ethnic variation for four environmental behaviors: environmental reading, household recycling, environmental group joining, and participation in nature-based outdoor recreation. Blacks and foreign-born Latinos were less likely than Whites to score higher on the NEP. Any behavioral differences between Whites and the respective minority groups were expected to diminish with the inclusion of the NEP as an intervening variable in the model between ethnicity and behavior. However, ethnic differences remained stable and strong even when environmental belief was added. Overall, Asian American and U.S.-born Latino environmentalism was most similar to Whites. African American concern and behavior was least similar to White environmentalism. Gender, age, and liberal political orientation were also consistent explicators for both environmental concern and behavior. C1 USDA, So Res Stn, Forest Serv, Athens, GA USA.

To test these probe and primer sets for their ability to monitor changes in gene expression, groups of fish were experimentally challenged either via daylength, vitamin availability, or with pathogenic microorganisms. The probes and primers sets were then used to analyze expression levels of specific gene products from isolated RNA. The expression of certain genes such as myosin in muscle correlated significantly with protein intake and seasonal daylength. Other genes involved with growth and metabolism such as insulin-like growth factor and pyruvate kinase showed lower levels of significance in correlating with planes of nutrition and varied with diet and treatment. However differences for pyruvate kinase were found in early tests done with animals receiving a vitamin-reduced diet. For factors relating immunological status after infection with microbiological pathogens, several factors such as MX-1 and CD-8 correlated with dose of the viral pathogen infectious hematopoeitic necrosis virus. Association of pathogen dose with immunological expression level was much less pronounced when fish were tested with bacterial microorganisms. This work will aid in evaluating the effects of diet on fish health and nutrient utilization and for evaluating the effects of selection of trout strains.

Although the search for indicators has led to the development of criteria for good indicators, it has also been dominated by scientific elites. The consequences of such dominance leads to significant social and policy implications, particularly with regard to how the search for sustainability has become defined primarily as a technical/scientific exploration when it is actually a moral and ethical issue. Our discussion about sustainability and appropriate indicators centers on what constitutes the public interest, a question that requires inclusiveness and centers on the interface of science and policy. The paper reviews the rationale for selecting indicators, the functions they serve, and the implications and consequences involved when one sector-science-dominates the debate. The paper concludes with suggestions about appropriate roles of science, policy and the public in the indicator selection process.

Runoff from vegetable production utilizing polyethylene mulch can contain up to 35% of applied copper, a widely used fungicide/bactericide that has adverse effects on aquatic organisms. Copper is primarily transported in runoff with suspended particulates; therefore, implementation of management practices that minimize soil erosion will reduce copper loads. Replacing bare-soil furrows with furrows planted in rye (Secale cereale) significantly improved the sustainability of vegetable production with polyethylene mulch and reduced the potential environmental impact of this management practice. Vegetative furrows decreased runoff volume by >40% and soil erosion by >80%. Copper loads with runoff were reduced by 72% in 2001, primarily as a result of reduced soil erosion since more than 88% of the total copper loads were transported in runoff with suspended soil particulates. Tomato yields in both years were similar between the polyethylene mulch plots containing either bare-soil or vegetative furrows. Replacing bare-soil furrows with vegetative furrows greatly reduces the effects of sediments and agrochemicals on sensitive ecosystems while maintaining crop yields.

An extensive simulation study was conducted to find the optimum number, g, of population members to be encountered from each random starting point in ordered distance sampling. Monte Carlo simulations covered 64 combinations of four spatial patterns, four densities and four sample sizes. Values of g from I to 10 were considered for each case. Relative root mean squared error (RRMSE) and relative bias were calculated for each level of g, with RRMSE used as the primary assessment criterion for finding the optimum level of g. A non-parametric confidence interval was derived for the density estimate, and this was included in the simulations to gauge its performance. Superior estimation properties were found for g > 3, but diminishing returns, relative to the potential for increased effort in the field, were found for g > 5. The simulations showed noticeable diminishing returns for more than 20 sampled points. The non-parametric confidence interval performed well for populations with random, aggregate or double-clumped spatial patterns, but rarely came close to target coverage for populations that were regularly distributed. The non-parametric confidence interval presented here is recommended for general use. Published in 2004 by John Wiley Sons, Ltd.

We investigated if homocysteine promotes left ventricular (LV) remodelling. Methods and results We examined cross-sectional relations of plasma total homocysteine to echocardiographic LV structure and function in 2697 Framingham Heart Study participants (mean age 58 years, 58% women) free of heart failure and previous myocardial infarction. Adjusting for age and height, plasma homocysteine was positively related to LV mass, wall thickness, and relative wall thickness in women (p = 0.0004-0.04), but not in men (p = 0.28-0.68). Adjusting additionally for other clinical covariates, the relations of plasma homocysteine to LV mass and wall thickness in women remained statistically significant, but the relation to relative watt thickness became of borderline significance (1.92 g, 0.01 cm, and 0.29% increase, respectively, for a 1-SD increase in ln[homocysteine], p = 0.01-0.08). LV mass and watt thickness were higher in the fourth quartile of plasma homocysteine compared to the lower three in all models in women (p = 0.0003-0.02), but not in men (p = 0.25-0.78). Plasma homocysteine was not related to left atrial. size or LV fractional shortening in either sex. Conclusion In our community-based sample, plasma homocysteine was directly related to LV mass and wall thickness in women but not in men. (C) 2004 The European Society of Cardiology.

We investigated factors potentially associated with tHcy concentration in a cohort of type 2 diabetic subjects. Materials and methods The common methylene tetrahydrofolate reductase (MTHFR) C677T polymorphism, fasting tHcy, vitamin B12 and folate plasma levels were assessed in 312 diabetic subjects, whose clinical, metabolic and lifestyle information was also available. Results The MTHFR genotype distribution was comparable to the Hardy-Weinberg equilibrium, with an overall TT homozygous frequency of 22%. Fasting tHcy concentration was significantly higher in men than in women (P < 0.001). Multivariate-adjusted tHcy concentration was significantly different across the quartiles of age (P < 0.001), folate (P = 0.01), vitamin B12 (P = 0.03), creatinine concentrations (P = 0.001) and smoking (P = 0.02). Overall, significant trends were noted for creatinine clearance (P for trend = 0.02) and systolic blood pressure (BP) (unadjusted P for trend = 0.01), whereas no differences were noted according to BMI, diastolic BP, presence of hypertension, and diabetes-related variables, such as diabetes duration, fasting glucose and glycated haemoglobin concentrations, current treatment and diabetes long-term complications. Total homocysteine levels significantly correlated with age, systolic BP, vitamin B12, creatinine and creatinine clearance, but only age, creatinine, folate and vitamin B12 levels were independently associated with tHcy concentration in stepwise regression analysis. Conclusions Age, creatinine, folate, vitamin B12, and to a minor extent, sex, smoking, TT genotype and systolic BP were significantly associated with Hcy plasma concentration in type 2 diabetes, whereas no significant associations were noted with diabetes-related variables.

In most cases, elemental iron powders are utilized as fortificants due to their lower cost and few, if any, sensory problems. However, their bioavailability is unknown. We aimed to measure the bioavailability of H-2-reduced elemental iron powder in white wheat bread made from 72% extraction flour. Design: A stable isotope of H-2-reduced iron powder (mean particle size 15 mum) was used as fortificant in bread prepared from unfortified wheat flour. In all, 12 5- to 7-y-old children were fed bread with 4 mg of H-2-reduced Fe-58/100 g of flour. The next day Fe-57 ascorbate was given as reference dose. After 14 days, erythrocytes were analyzed for isotopic enrichment using mass spectrometry. Results: When normalized to 40% absorption of the reference dose, the geometric mean (+/-range of 1 s.d.) bioavailability of reduced Fe-58 in wheat bread rolls was 6.5% (3.7-11.8). Conclusions: When compared to previous radioiron studies of ferrous sulfate showing 10% absorption from an identical meal in adult women, the relative bioavailability can be estimated at about 65%. However, the bioavailability of this smaller particle size Fe-58 (15 mum) is likely to be higher than that of commercial iron powder (45 mum) although the precise difference cannot be ascertained with current methods. Thus, the bioavailability of commercial elemental iron powders currently used in fortification programs is likely to be substantially lower than that of ferrous sulfate.

Experiments were conducted to test the effect of phosphorous added to soil-less mixes or to nutrient solutions used for irrigation on soft-rot caused by Erwinia carotovora subsp. carotovora (Ecc). Soft-rot incidence increased to 51% when soil-less mix was amended with superphosphate in comparison to regular soil-less mix ( no superphosphate added) (31%). In contrast, addition of phosphorous in the nutrient solution met the phosphorous needs of the plant without enhancing soft-rot. Plant height, fresh mass, and number of flowers per plant were greater in calla lilies irrigated with nutrient solution containing phosphorous than no phosphorous treatments. Similar results were obtained in tests conducted in a commercial greenhouse with larger sample size. No statistical differences were found between tubers sprayed with water ( control) or with a 0.5 mM solution of KH2PO4 in laboratory experiments to determine the effect of phosphorous on tuber root development. In other experiments, tubers were sprayed with either water, a bacterial cell suspension 1 x 10(2) cfu ml(-1), a solution of 0.5 mM KH2PO4, or a suspension of bacteria in KH2PO4. The results from these tests showed a significant increase of soft-rot development in tubers treated with the suspension of Ecc prepared in a solution of KH2PO4 relative to other treatments. Further laboratory tests indicated that enzymatic activity ( polygalacturonase and pectate lyase) of Ecc increased when grown in the presence of phosphorous. These experiments suggest that increased soft-rot in the presence of phosphorous is due to increased virulence of Ecc.

A bacterial disease has affected the A. tequilana crop in recent years. Previous reports based on colony and cell morphology, Gram stain and potato rot indicated that Erwinia sp. is the main pathogen. We isolated a several bacterial isolates capable of producing soft-rot symptoms in greenhouse pathogenicity assays. An extensive characterisation involving pathogenicity tests, fatty acid profile, metabolic and physiological properties, ribosomal DNA sequence and intergenic transcribed spacer amplification (ITS-PCR) and restriction banding pattern (ITS-RFLP) was made of each isolate. Three different species: Erwinia cacticida, Pantoea agglomerans and Pseudomonas sp. were identified. Fatty acid and metabolic profiles gave low similarity values of identification but 16S rDNA sequence, ITS-PCR and ITS-RFLP confirmed the identification of E. cacticida. In the phylogenetic tree, E. cacticida from blue agave was grouped neither with E. cacticida type strains nor with Erwinia carotovora. This is the first report that associates E. cacticida with A. tequilana soft-rot symptoms. C1 IPN, Ctr Invest & Estudios Avanzados, Dept Biochem & Biotechnol, Irapuato 36500, Mexico.

The OMP fraction was analyzed using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and compared to whole-cell lysate, purified lipopolysaccharide (LPS) and a crude cell-wall fraction. The OMP fraction contained less than 2% (WN) LPS. SDS-PAGE showed that whole cell lysates contained 27 proteins from 107 to 14.3 kDa, whereas OMP contained nine proteins from 97 to 14.3 kDa, LPS contained two proteins at 45 and 37 kDa bands and a smear of bands below 14.3 kDa, and cell wall fraction contained 21 proteins from 97 to 8 kDa. Channel catfish, Ictalurus punctatus, were vaccinated with 12.5 mug/100 mul OMP and immunogenicity was confirmed by subsequent Western blots. Blots showed that 97, 80, and 19 kDa proteins were immunogenic. Rapid enzyme-linked inummosorbent assays (ELISA) demonstrated that OMP produced a weak, but observable antibody response by 21 days post injection. OMP concentrations of 3.13, 6.25, 12.5, 25, and 50 mug/100 mul total protein were tested for protective immunity. Marginal protection by relative percent survival (RPS) was only seen for fish injected with 12.5 mug/100 mul with RPSs between 55-67.5%. A booster dose of 12.5 mug/100 mul OMP did not significantly enhance protection. (C) 2003 Elsevier Ltd. All rights reserved. C1 USDA ARS, Aquat Anim Hlth Res Lab, Auburn, AL 36831 USA.

First in-stars of the ladybeetles Cycloneda sanguinea L., Curinus coeruleus Mulsant, Harmonia axyridis Pallas and Olla v-nigrum Mulsant (Coleoptera: Coccinellidae) and the lacewing Chrysoperla rufilabris Burmeister (Neuroptera: Chrysopidae) survived topical sprays of sucrose octanoate at 8,000 ppm without significant mortality, a concentration corresponding to twice the recommended field rate required to kill aphids and other soft bodied pests. Similarly, adults of the red scale parasitoid, Aphytis melinus De Bach (Hymenoptera: Aphelinidae) and second in-stars of the predatory bug Orius insidiosus (Say) (Hemiptera: Anthocoridae) survived 24 h exposures to residues of 8,000 ppm sucrose octanoate on leaf disks without significant mortality. The efficacy of sucrose octanoate as a contact insecticide against various homopteran pests of citrus, combined with its low toxicity to key beneficial insects in the citrus ecosystem, suggest that it may be a valuable material for incorporation into IPM programs for Florida citrus.

Negative effects of copper on insect development were observed only for early instars. Survival of larvae from hatching to 4 weeks of age was significantly affected by the copper compounds compared with the artificial diet alone, and greater mortality was associated with CuSO4 compared with Cu(OH),. The two compounds had equivalent effects on larval weight gain of early instars. Weight gain was negatively correlated with increasing copper concentration. No effect of copper was observed on late instars maintained on these diets beyond the initial 4 weeks. Larval and pupal period, weight gain, and survival of late instars were statistically similar. No effect on larval survival or weight gain was observed when copper solutions were applied at nonphytotoxic levels to two varieties of citrus rootstock. The potential for manipulating citrus tree copper content to control this pest is discussed. C1 USDA ARS, US Hort Res Lab, Ft Pierce, FL 34945 USA. Morse Enterprises Ltd Inc, Miami, FL 33129 USA.

An overall infestation (= approach) rate of 10.4% was found, with the rate for aircraft arriving from Central American countries noticeably greater at about 23%. Quarantine-significant taxa from 33 families in five orders were detected, with members of Lepidoptera and Coleoptera most frequently encountered. More than 40% of infested aircraft contained multiple insect taxa. No correlation was established between the presence of hitchhiking insects and the time of day (night vs. day) during which cargo was loaded at points of origin or the nature of cargo on board. Quarantine-significant organisms arrived in cargo aircraft during all months of the year. Significant seasonality (dry season vs. wet) was observed for pests on flights arriving from Central America, with separate peaks rioted in May and October.

Mean granule length and width of the starches separated from mango cultivars ranged between 15.8-21.7 and 8.7-14.1 mum, respectively. The shape of starch granules varied from oval to elliptical. Amylose content of mango kernel starches from different cultivars ranged from 9.1 to 16.3%. Totapuri kernel starch, with the largest mean granular size, had the highest amylose content, while Chausa kernel starch, with the lowest mean granular size had the lowest amylose content. The transition temperatures (T-o, T-p and T-c) and enthalpy of gelatinization (DeltaH(gel)) were determined using differential scanning calorimetry (DSC). T-o, T-p and T-c varied from 73.4 to 76.3, 78.1 to 80.3 and 83.0 to 85.7 degreesC, respectively. Chausa kernel starch showed the highest T-o, T-p, T-c, DeltaH(gel) and peak height index among starches from different mango cultivars. The rheological properties of the starches from different mango cultivars measured using a dynamic rheometer, showed significant variations in the peak G', G" and peak tan delta values. Totapuri kernel starch showed the highest peak G', G", breakdown in G' and lowest peak tan 3 values. The large-size granules of Totapuri kernel starch appeared to be associated with higher values of peak G' and G". The turbidity of the gelatinized aqueous starch suspensions, from all mango cultivars, increased with increase in storage period. Dashehari starch paste showed lower turbidity values than other mango cultivars. (C) 2003 Elsevier Ltd. All rights reserved.

Many innovations have been developed over the last several decades to achieve these goals. Innovations typically work their way backwards in the manufacturing process, with an increasing level of monitoring occuring at the end of a production line. There exists, however, an ever-increasing array of tools available to forest products, manufacturers that allow rapid assessment of material and product variables throughout the manufacturing process. A technology that shows great potential in all facets of material assessment is near infrared (NIR) spectroscopy. The potential for NIR technologies has not gone unnoticed by the wood research community and there are scores of national and international laboratories developing appropriate applications. The rapid assessment of solid wood properties using NIR spectra is a fast-growing field that has broad implications in relation to wood quality and, ultimately, tree improvement. NIR as a means of online monitoring during the manufacturing process has also spurred many laboratories to examine potential applications for wood composites. It is probable that this type of monitoring will lead to increases in efficiency and profits. C1 Louisiana State Univ, Ctr Agr, Sch Renewable Nat Resources, Baton Rouge, LA 70803 USA.

Recycling of preservative-treated wood has great potential. In this study, flakeboard was produced from decommissioned guardrail posts that had been treated with chromated copper arsenate (CCA). The leaching characteristics of chromium, copper, and arsenic from flakeboards manufactured from five different ratios of recycled CCA-treated wood and untreated virgin southern pine wood were investigated. Five ratios of recycled CCA-treated wood and virgin, untreated wood were used for flakeboard furnish. The ratios were 100:0, 75:25, 50:50, 25:75, and 0:100. The guardrails generally showed higher amounts of CCA in the outer horizontal areas and the middle vertical regions of the guardrail posts. As expected, the furnishes with greater amounts of CCA-treated wood had higher leaching values. C1 Louisiana State Univ, Ctr Agr, Sch Renewable Nat Resources, Baton Rouge, LA 70803 USA.

As an alternative to strategies that employ sequence conservation, an approach utilizing conserved gene order could facilitate the cloning of A mating-type genes from mushroom fungi. It has been shown that a gene encoding a mitochondrial intermediate peptidase (MIP) is very close (<1 kbp) to the A mating-type locus of two model mushroom species. In this study, the cosegregation of MIP and the A mating-type locus was studied by genotyping progeny of seven additional mushroom species using PCR and genetic crosses. No evidence of any recombination between MIP and the A mating-type locus was detected among all seven species. Phylogenetic analysis of MIP sequences from diverse mushroom species agrees with the current organismal phylogeny, suggesting the sequences are generally orthologous. (C) 2003 Elsevier Inc.

A wild-like weedy strain SS18-2 was selected to investigate the genetic architecture underlying seed dormancy, a critical adaptive trait in plants. A framework genetic map covering the rice genome was constructed on the basis of 156 BC1 [EM93-1 (nondormant breeding line)//EM93-1/SS18-2] individuals. The mapping population was replicated using a split-tiller technique to control and better estimate the environmental variation. Dormancy was determined by germination of seeds after 1, 11, and 21 clays of after-ripening (DAR). Six dormancy QTL, designated as qSD(S)-4, -6, -7-1, -7-2, -8, and -12, were identified. The locus qSD(S)-7-1 was tightly linked to the red pericarp color gene Rc. A QTL X DAR interaction was detected for qSD(S)-12, the locus with the largest main effect at 1, 11, and 21 DAR (R-2 = 0.14, 0.24, and 0.20, respectively). Two, three, and four orders of epistases were detected with four, six, and six QTL, respectively. The higher-order epistases strongly suggest the presence of genetically complex networks in the regulation of variation for seed dormancy in natural populations and make it critical to select for a favorable combination of alleles at multiple loci in positional cloning of a target dormancy gene.

Stable carbon isotope (delta(13)C) values and associated radiocarbon ages from soil organic matter (SOM) were used to evaluate vegetation change across five landscape positions at a small enclosed basin in southeastern Arizona. Light and dense SOM fractions were separated to distinguish recent vegetation changes. The direction and timing of vegetation change differed with landscape position along a gentle elevation gradient from the basin outlet to a nearby volcanic ridge top. C-4 perennial grasses have dominated the basin outlet, center, and toe slope landscape positions since at least 5000-6000 years BP, except for the dominance Of C-3 plants at the bottom of the outlet excavation at 5000 years BP. This isotopic change is associated with rounded cobbles that may have been a stream channel, suggesting the presence Of C-3 herbaceous or woody riparian vegetation. On midslope and ridge top landscape positions, where semidesert shrubs now dominate, the proportion of plants with C-4 metabolism calculated from mass balance mixing formulas decreased from approximately 60% as recently as 400 years BP to only 1.5% observed today. The light SOM fraction from mid-slope and ridge top surface soil horizons was approximately 30% C-4 and had a post-bomb date, suggesting that the conversion from grass to shrub occurred over the last several decades.

Variable sediment supply from within and outside of the channel led to a complex pattern of scour and fill hysteresis. Despite the large flood magnitude, large portions of the bed did not scour. Scour was observed at three distinct locations: two of these were adjacent to large woody debris (LWD), and the third was along the flow path deflected by a major LWD obstruction. Bed material texture showed little change in size distribution of either surface or subsurface material, suggesting lack of disruption of the pre-flood bed. Fractions larger than the median size of the bed surface material were rarely mobile. Sediment rating relations were similar, although temporal variation within and among stations was relatively high. Relations between bed load size distribution and discharge were complex, showing coarsening with increasing discharge followed by fining as more sand was mobilized at high flow. Lack of local scour in the pool combined with bed load fining and net fill by relatively fine material implied that the dominant sources of mobile sediment were upstream storage sites and local bank collapse. Patterns of flow, channel dynamics, and sediment mobility were strongly affected by a LWD flow obstruction in the pool centre that created turbulent effects, thereby enhancing entrainment and transport in a manner similar to scour at bridge piers.

SO GEOMORPHOLOGY LA English DT Article DE suspended sediment; effective discharge; reference conditions; ecoregions ID STREAMS; RIVERS; FREQUENCY; MAGNITUDE; PATTERNS AB Historical flow and suspended-sediment transport data from more than 2900 sites across the United States have been analyzed in the context of estimating flow and suspended-sediment transport conditions at the 1.5-year recurrence interval flow (Q(1.5)). This is particularly relevant with the renewed focus on stream restoration activities and the urgency in developing water-quality criteria for sediment. Data were sorted into the 84 Level III ecoregions to identify spatial trends in suspended-sediment concentrations and yields to meaningfully describe suspended-sediment transport rates across the United States. Arguments are developed that in lieu. of form-based estimates of say the bankfull level, a flow of a given recurrence interval (Q(1.5)) is more appropriate to integrate suspended-sediment transport ratings for the purpose of defining long-term transport conditions at a site (the "effective discharge"). The use of the Q(1.5) as a measure of the effective discharge for suspended-sediment transport is justified on the basis of literature reports and analytic results from hundreds of sites in 17 ecoregions that span a diverse range of hydrologic and topographic conditions (i.e., Coast Range, Arizona/New Mexico Plateau, Mississippi Valley Loess Plains, Middle Atlantic Coastal Plain). There is sufficient data to also develop regional curves for the Q(1.5) in all but eight of the ecoregions. At the Q(1.5) the highest median suspended-sediment concentrations occur in semiarid environments (Southwest Tablelands, Arizona/New Mexico Plateau and the Mojave Basin and Range); the highest yields occur in humid regions with erodible soils and steep slopes or channel gradients (Mississippi Valley Loess Plains [MVLP] and the Coast Range). Suspended-sediment yields for stable streams are used to determine "background" or "reference" sediment transport conditions in eight ecoregions where there is sufficient field data. The median value for stable sites within a given ecoregion are generally an order of magnitude lower than for nonstable sites. Published by Elsevier B.V.

Location We have used data from across Eurasia. Methods The relationships between litterfall and climatic factors were examined using linear regression analysis of a compilation of published data from coniferous and broadleaf forests in Eurasia. Results The relationships between litterfall and climatic factors show that in the temperate, subtropical, and tropical areas, broadleaf forests had higher litterfall than coniferous ones, whilst the opposite was found for boreal forests. Combining all climatic zones, a multiple regression analysis using annual mean temperature (T) and annual precipitation (P) as independent variables gave an adjusted R-2 (R-adj(2)) of 0.272 for total litterfall in coniferous forests (n = 199, P < 0.001), 0.498 for broadleaf litterfall (n = 240, P < 0.001), and 0.535 for combined coniferous and broadleaf litterfall (n = 439, P < 0.001). The linear models for broadleaf stands have significantly higher coefficients for T and P than those for coniferous ones but the intercepts were similar. Thus, litterfall in broadleaf forests increased faster with T and P than that in coniferous forests. Further, a transformation of temperature and precipitation to relative units showed that a relative-unit change in T had a larger impact than P on total litterfall in broadleaf forests. The results indicate that at a continental scale, climatic controls over litterfall differ between coniferous and broadleaf forests. Conclusions A relative unit change in annual mean temperature has a greater effect on litterfall compared to the same change in annual precipitation across the Eurasian forests. Further, the higher response to T for broadleaf forests indicates a difference in climate control between coniferous and broadleaf forests at a continental scale, and consequently different litterfall responses to climate change.

It is important for livestock producers to begin grazing annual ryegrass as early as possible and any management practices maximizing early season production could be beneficial. To assess the impact of seeding rate on subsequent yield, yield distribution, quality, seedling density, and end-of-season plant and tiller density, a 2-year study was initiated at four locations in Louisiana. Three annual ryegrass cultivars, varying in seed size, were established at four seeding rates based on pure live seed (PLS) rates of 400, 800, 1200 and 1600 PLS m(-2). There was no advantage in total yield from increasing seeding rates beyond 800 PLS m(-2). However, first-harvest yields increased from 360 to 930 kg dry matter (DM) ha(-1) as seeding rate increased from 400 to 1600 PLS m(-2). Crude protein and neutral-detergent fibre concentrations, and in vitro DM digestibility, were not affected by seeding rate. Seedling density and end-of-season plant numbers increased as seeding rate increased. However, stems per plant decreased as seeding rate increased, indicating compensatory tillering for the reduced plant numbers observed at the lower seeding rates.

SO GROUND WATER MONITORING AND REMEDIATION LA English DT Article ID POLYMERASE CHAIN-REACTION; SEWAGE-TREATMENT PLANTS; ANTIMICROBIAL RESISTANCE; ESCHERICHIA-COLI; GROUNDWATER; LEGIONELLA; SALMONELLA; EFFLUENT; FATE; ENVIRONMENT AB A proof-of-concept experiment was devised to determine if pharmaceuticals and other organic waste water compounds (OWCs), as well as pathogens, found in treated effluent could be transported through a 2.4 m soil column and, thus, potentially reach ground water under recharge conditions similar to those in and or semiarid climates. Treated effluent was applied at the top of the 2.4 m long, 32.5 cm diameter soil column over 23 days. Samples of the column inflow were collected from the effluent storage tank at the beginning (T-begin) and end (T-end) of the experiment, and a sample of the soil column drainage at the base of the column (Bend) was collected at the end of the experiment. Samples were analyzed for 131 OWCs including veterinary and human antibiotics, other prescription and nonprescription drugs, widely used household and industrial chemicals, and steroids and reproductive hormones, as well as the pathogens Salmonella and Legionella. Analytical results for the two effluent samples taken at the beginning (Tbegin) and end (Tend) of the experiment indicate that the number of OWCs detected in the column inflow decreased by 25% (eight compounds) and the total concentration of OWCs decreased by 46% while the effluent was in the storage tank during the 23-day experiment. After percolating through the soil column, an additional 18 compounds detected in Tend (67% of OWCs) were no longer detected in the effluent (Bend) and the total concentration of OWCs decreased by more than 70%. These compounds may have been subject to transformation (biotic and abiotic), adsorption, and (or) volatilization in the storage tank and during travel through the soil column. Eight compounds-carbamazapine; sulfamethoxazole; benzophenone; 5-methyl-1H-benzotriazole; N, N-diethyltoluamide; tributylphosphate; tri(2-chloroethyl) phosphate; and cholesterol-were detected in all three samples indicating they have the potential to reach ground water under recharge conditions similar to those in and and semiarid climates. Results from real-time polymerase chain reactions demonstrated the presence of Legionella in all three samples. Salmonella was detected only in Tbegin, suggesting that the bacteria died off in the effluent storage tank over the period of the experiment. This proof-of-concept experiment demonstrates that, under recharge conditions similar to those in and or semiarid climates, some pharmaceuticals, pathogens, and other OWCs can persist in treated effluent after soil-aquifer treatment.

However, the mechanisms controlling either the dispersal process itself or our estimation of that process may be influenced by site-specific factors such as local forest structure and nonuniform adult genetic structure. Here, we present an extension of the AMOVA model applied to the recently developed TWOGENER analysis of pollen pool structure. This model, dubbed the Stepwise AMOVA (StAMOVA), focuses on determining to what extent ecological, demographic, and/or environmental factors influence the observed genetic variation in spatially separated pollen pools. The analysis is verified for efficacy, using an extensive battery of simulations, illustrating: ( 1) how nonuniform adult genetic structure influences the differentiation of spatially separated pollen pools, and ( 2) how effectively the Stepwise analysis performs in carrying out the appropriate corrections. Finally, the model is applied to a Quercus alba data set, from which we have prior evidence that the adult genetic structure is nonuniformly distributed across the sampling landscape. From this data set, we show how the Stepwise model can be applied to remove the effects of spatial adult genetic structure on pollen pool differentiation and contrast these results with those derived from the original TWOGENER analysis.

Landslides and debris flows transported sediment and woody debris in headwater tributaries in 1961, 1979, and 1993. Widespread landsliding in 1961 and 1993 was triggered by rainstonns with recurrence intervals (24 h precipitation) of 7.0 years and 4.2 years respectively. Occurrence. distribution, and downstream effects of these mass movements were controlled by landform characteristics such as channel gradient and valley configuration. Landslides and channelized debris flows created exposed bedrock reaches, log jams, fans, and abandoned channels. The terminus of the deposits did not enter main channels because debris flows spread and thinned on the unconfined bottom of the U-shaped glaciated valley. Chronic sediment input to channels included surface erosion of exposed till (rain splash, sheet erosion, and freeze-thaw action) and bank failures. Bedload sediment transport in a channel impacted by 1993 landslides and debris flows was two to ten times greater and relatively finer compared with bedload transport in a young alder riparian channel that had last experienced a landslide and debris flow in 1961. Sediment transport and storage were influenced by regeneration of riparian vegetation, storage behind recruited woody debris, development of a streambed armour layer, and the decoupling of hillslopes and channels. Both spatial and temporal variations of sediment movement and riparian condition are important factors in understanding material transport within headwaters and through channel networks.

In order to exploit these advantages, a regeneration system is required to achieve these transformation-based goals. Carbohydrate source and concentration were evaluated to improve somatic embryo (SE) production and desiccation treatments to improve the conversion efficiency of SEs to plants in a diploid Gossypium arboreum accession, A(2)-9 (PI-529712). Improved SE numbers and their subsequent conversion into plantlets was achieved with a Murashige and Skoog (MS)/sucrose-based medium M-2 [0.04M sucrose, 0.3 muM alpha-naphthaleneacetic acid (NAA)]. On this medium, 219 embryos per g initiated, and close to 11% of these embryos germinated into plantlets. Neither a 5-d desiccation treatment of embryogenic callus previously cultured in liquid medium nor filter paper insertion improved the numbers of SEs induced or their conversion to plantlets. A 3-d desiccation period resulted in improved plant regeneration. When immature G. arboreum SEs induced on M-I (0.2 M glucose, 2.6 muM NAA, and 0.2 muM kinetin) medium underwent a 3-d desiccation treatment, 49% of these immature SEs were converted to plantlets after a 4-wk period on M-2 medium. These improved results will help to pave the way for future genetic transformation and associated gene structure and function studies utilizing G. arboreum. These results, in particular the 3-d desiccation treatment, can also be incorporated into regeneration protocols to improve the regeneration efficiency of other Gossypium species.

To meet these two requirements, meadowfoam estolide was fractionated into monoestolide (dimer) and polyestolide (oligomers) by short-path molecular distillation. The distilled monoestolide had a Gardner Color of one compared with the undistilled material with a Gardner of 12. Flow rates and rotor temperatures were varied and the resultant fractionation of mono- and polyestolide were observed. Monoestolide in the distillate was increased to 89% (unprocessed material had 64% monoestolide) in a single-pass distillation (rotor temperature = 200 degreesC) with residual monoestolide concentration in the residue of 18%. Multiple-pass distillation removed all of the monoestolide from the residue fraction. The split ratio (distillate to residue) was highest at the lower flow rate with the highest rotor temperature (325 degreesC). However, considerable amount of co-distillation of polyestolide (50%) was observed. Rotor temperatures beyond 250degreesC gave significant declines in the purity of the distilled monoestolide even though the observed split ratio increased. Residual monoestolide composition in the residue was identical for both the low and high flow rates. In conclusion, meadowfoam estolide was successfully distilled into a low-color monoestolide fraction suitable for cosmetic applications using a laboratory molecular distillation unit and high vacuum.

Oil Red was evaluated as a histochemical stain for the waxy components on the surface of cotton and flax fibers and of plant cuticles. A positive reaction for arachidyl stearate and differential staining of fibers after sequential extraction of fatty acids and alcohols indicated that Oil Red stained wax components in plant materials. For cotton (Gossypium hirsutum) fibers, Oil Red stained to a greater extent the regions closest to the seed coat, especially at points where fibers attached to the seed coat. Fiber regions at a distance from the seed coats stained irregularly, suggesting that the wax was unevenly distributed. Flax (Linum usitatissimum) bast fibers, in contrast, did not stain with Oil Red, but the protective stem cuticle was intensely stained. The positive histochernical reaction for cuticle identified non-fiber fragments in processed and cleaned flax fibers, thus providing a quick method to detect visually trash components in fiber and products. Likewise, bast fibers from kenaf (Hibiscus cannabinus) did not stain well with Oil Red, whereas the stem cuticle gave a positive reaction. The general usefulness of Oil Red as a histochemical stain for the plant cuticle was demonstrated in leaves and stems of mature corn (Zea mays) and fresh bermudagrass (Cynodon dactylon) leaves. Oil Red provides a quick, qualitative histochemical method to demonstrate the wax-containing cuticle in plants. (C) 2003 Elsevier B.V. All rights reserved.

The SSGP-11A1 gene contains one small intron (89 bp) and encodes a putative protein with 79 amino acids. The first 18 amino acids constitute a putative secretion signal peptide. The SSGP-12A1 gene contains three small introns and encodes a putative protein with 234 amino acids. The first 19 amino acids constitute a putative secretion signal peptide. Northern blot analysis revealed that both of the genes are primarily expressed in the salivary glands of Hessian fly larvae, the feeding stage of the insect. These observations are consistent with the possibility that the proteins encoded by them are secreted into host plants during feeding. Even though both genes are exclusively expressed in Hessian fly larvae, the expression profiles between them were quite different in insects at different instars. The SSGP-11A1 gene was expressed in all instars of larvae while the SSGP-12A1 gene was almost exclusively expressed in the first instar larvae. The differential expression suggests that the proteins encoded by these two genes may perform different functions. In situ hybridization revealed that the SSGP-11A1 gene is located on the short arm of chromosome A1 while SSGP-12A1 gene is on the long arm of chromosome A2. (C) 2003 Elsevier Ltd.

Our studies suggest that both (Z)-5-dodecenol and (Z,E)-5,7-dodecadienol can be biosynthetically derived from chain elongation of palmitate to stearate in the gland, and its subsequent All desaturation to produce (Z)-11-octadecenoate. After three cycles of 2-carbon chain-shortening, the pheromone glands produce (Z)-5-dodecenoate, which is then converted to (Z)-5-dodecenol by reduction. A second Delta11 desaturation of (Z)-9-hexadecenoate produces (Z, E)-9,11-hexadecadienoate, which is then chain shortened in two cycles of beta-oxidation and finally converted to (ZE)-5,7-dodecadienol by reduction.

By screening a BAC library of genomic DNA from T castaneum (Tc) with a DNA probe encoding the catalytic domain of a putative Tribolium CHS, several clones that contained CHS genes were identified. Two distinct PCR products were amplified from these BAC clones and confirmed to be highly similar to CHS genes from other insects, nematodes and fungi. The DNA sequences of these genes, TcCHS1 and TcCHS2, were determined by amplification of overlapping PCR fragments from two of the BAC DNAs and mapped to different linkage groups. Each ORF was identified and full-length cDNAs were also amplified, cloned and sequenced. TcCHS1 and TcCHS2 encode transmembrane proteins of 1558 and 1464 amino acids, respectively. The TcCHS1 gene was found to use alternate exons, each encoding 59 amino acids, a feature not found in the TcCHS2 gene. During development, Tribolium expressed TcCHS1 predominantly in the embryonic and pupal stages, whereas TcCHS2 was prevalent in the late larval and adult stages. The alternate exon 8a of TcCHS1 was utilized over a much broader range of development than exon 8b. We propose that the two isoforms of the TcCHS1 enzyme are used predominantly for the formation of chitin,in embryonic and pupal cuticles, whereas TcCHS2 is utilized primarily for the synthesis of peritrophic membrane-associated chitin in the midgut.

SO INTERNATIONAL GEOLOGY REVIEW LA English DT Article ID KLAMATH MOUNTAINS; SIERRA-NEVADA; EVOLUTION; TOPOGRAPHY; PATTERNS; GEOLOGY; FLORA AB We analyzed botanical, geologic, and climatic data in an effort to understand why there are many more serpentine endemics - i.e., plant species restricted to ultramafic substrates-in some regions of California than in others. We found that, in addition to elevational range (which subsumed the effect of serpentine area) and annual rainfall, the age of exposure of serpentine explained significant geographic variation in the diversity of endemic plant species. Estimated ages of subaerial exposure are generally higher in the Klamath and northern Coast Range serpentines than in Sierra Nevadan and southern Coast Range analogues, paralleling the trends in endemic plant diversity. However, the fit of the relationship is weakened by the southern Sierran serpentines, which are apparently long-exposed yet poor in endemic plant species. These results have significance for understanding local ecological processes, because we have also found that the diversity of endemic species within 50 x 10 m field plots is best predicted by the diversity of endemics in the surrounding region, which in turn is a function of the age of subaerial exposure.

Prescalded, picked, eviscerated, and chilled carcasses were obtained from a commercial processing facility, and psychrotrophs in the bacterial flora were enumerated on Iron Agar, Pseudomonas Agar, and STAA Agar. The size of the population of spoilage bacteria on processed carcasses stored at 4degreesC for 7, 10, or 14 days was also determined. Bacterial isolates were identified and dendrograms of the fatty acid profiles of the isolates were prepared to determine the degree of relatedness of the isolates. Findings indicated that although some processing steps increased the level of carcass contamination by selected bacteria, the number of spoilage bacteria recovered from processed carcasses was significantly (P less than or equal to 0.05) less than the number of bacteria recovered from carcasses entering the processing line. Acinetobacter and Aeromonas spp. were the primary isolates recovered from carcasses taken from the processing line. During refrigerated storage, there was a significant (P less than or equal to 0.05) increase in the population of bacteria on the carcasses, and Pseudomonas spp. were the predominant bacteria recovered from these carcasses. Dendrograms of the fatty acid profiles of the isolates indicated that bacterial cross-contamination of carcasses occurs during all stages of processing and that some bacteria can survive processing and proliferate on carcasses during refrigerated storage. Furthermore, cross-contamination was detected between carcasses processed on different days at the same facility. Findings indicate that although poultry processing decreases carcass contamination by psychrotrophic spoilage bacteria, significant levels of bacterial cross-contamination occur during processing, and bacteria that survive processing may multiply on the carcasses during refrigerated storage.

We have discovered naturally occurring compounds in the spent growth media, which inhibit the acid-tolerance ability of several enteric human pathogens when challenged at pH 3.0 for 2 h at 37degreesC. The compounds were detected in the spent growth media obtained from Escherichia coli O157:H7, Salmonella spp., and Vibrio cholera, but not from Shigella flexneri. The compounds were effective in reducing pathogen survival by 5-logs during acid-challenge assay. The low molecular weight (<300 Da) and heat resistant nature (121 degrees C, 15 min, at 15 psi) of the compounds make them excellent candidates to explore their suitability as food additives that would increase microbial food safety.

The current visual method for identifying damaged soybean seeds is based on discoloration and is subjective. The objective of this research was to classify healthy and fungal-damaged soybean seeds and discriminate among various types of fungal damage using near-infrared (NIR) spectroscopy. A diode-array NIR spectrometer, which measured reflectance [log(1/R)] from 400 to 1700 nm, was used to obtain spectra from single soybean seeds. Partial least square (PLS) and neural network models were developed to differentiate healthy and fungal-damaged seeds. The highest classification accuracy was more than 99% when the wavelength region of 490-1690 nm was used under a two-class PLS model. Neural network models yielded higher classification accuracy than the PLS models for five-class classification. The average of correct classifications was 93.5% for the calibration sample set and 94.6% for the validation sample set. Classification accuracies of the validation sample set were 100, 99, 84, 94, and 96% corresponding to healthy seeds, Phomopsis, Cercospora kikuchii, soybean mosaic virus (SMV), and downy mildew damaged seeds, respectively.

Seven-day-old sunflower plants were inoculated with a tagetitoxin-producing or nontoxigenic (control) strain of Pseudomonas syringae pv. tagetis. After 10 d, tagetitoxin-affected leaves were so severely chlorotic that they were white. Tagetitoxin-affected leaves had 99% less chlorophyll per unit fresh mass than control plant leaves. Electron microscopy of sections of chlorotic (toxin-affected) sunflower leaf cells revealed that leaf palisade and spongy parenchyma cells possessed few chloroplasts and that those present contained disorganized thylakoids and grana and no apparent starch grains. Rates of photosynthetic CO2 assimilation per unit leaf area in toxin-affected leaves were significantly lower than in control leaves. Compared to leaves of the control plants, the leaves of toxin-affected plants had significantly less free glucose, and less glucose was incorporated into sucrose and starch during the day. The parenchymatous cells of toxin-affected leaves had well-formed mitochondria with distinct internal membrane structure; however, dark respiration of the chlorotic sections of those leaves, monitored as dark CO2 evolution, was often significantly lower than in control leaves. Regardless of the time of day that leaves were sampled, the chlorotic leaves of toxin-affected plants had significantly lower levels of ascorbic acid than was detected in the control plant leaves. Thus, the study implied that carbohydrate products of photosynthetic CO2 assimilation such as glucose along with one or more functions of mitochondrial respiration were required for the synthesis of normal levels of ascorbic acid in green leaves. Further, the chlorotic sections of leaves of the toxin-affected sunflower plants often displayed the ability to maintain a range of 64% to 90% of the total foliar ascorbic acid present in the reduced form, even when the toxin-affected sunflower plants were exposed to elevated ozone levels (58 muL L-1 air) for 16 d. This observation indicates that the recycling of DHA to ASC by the ascorbate-glutathione cycle enzyme system remains functional in toxin-affected leaves when exposed to ozone-mediated oxidative stress.

On the basis of phylogenetic analysis of 16S rDNA sequences, elm yellows group phytoplasmas form a discrete subclade within the phytoplasma clade. Three phylogenetic parameters, namely 16S rRNA, ribosomal protein and secY genes, have been evaluated for their usefulness in differentiating elm yellows group phytoplasmas. RFLP analysis of 16S rRNA sequences differentiated the elm yellows group phytoplasmas into five subgroups. Twelve RFLP subgroups were differentiated on the basis of ribosomal protein and 13 were differentiated using secY gene sequences. Phylogenetic analysis of the ribosomal protein genes and sec Y gene alone or in combination indicated that the subgroups constitute 12 genetically distinct lineages, each of which appears to have evolved under different ecological constraints such as specific vector or plant hosts. On the basis of unique DNA and biological properties, it is proposed that the elm yellows phytoplasma EY1(T) represents a novel taxon, 'Candidatus Phytoplasma ulmi'.

Covariance components among traits were estimated using REML. Carcass traits were adjusted for age at slaughter. Estimates of heritability for hot carcass weight (HCWT); percentage of retail product; percentage of fat; percentage of bone; longissimus muscle area; fat thickness adjusted visually; estimated kidney, pelvic, and heart fat percentage; marbling score; Warner-Bratzler shear force; and taste panel tenderness measured on steers were moderate to high (0.26 to 0.65), suggesting that selection for carcass and meat traits could be effective. Estimates of heritability for taste panel flavor and taste panel juiciness were low and negligible (0.05 and 0.01, respectively). Estimates of heritability from cow data over all ages and seasons were high for MW, AMW, and HT (0.52, 0.57, 0.71; respectively) and relatively low for BCS (0.16). Pairwise analyses for each female mature trait with each carcass trait were done with bivariate animal models. Estimates of genetic correlations between cow mature size and carcass composition or meat quality traits, with the exception of HCWT, were relatively low. Selection for cow mature size (weight and/or height) could be effective and would not be expected to result in much, if any, correlated changes in carcass and meat composition traits. However, genetic correlations of cow traits, with the possible exception of BCS, with HCWT may be too large to ignore. Selection for steers with greater HCWT would lead to larger cows.

Selection response was evaluated for efficiency of gain, growth from birth through market weight, and carcass characteristics. Heritability and genetic correlations among traits were estimated using animal model analyses. Over a time-constant interval, selected lines were heavier, gained more weight, consumed more ME, and had more gain/ME than the control. Over a weight-constant interval, selected lines required fewer days, consumed less ME, had more efficient gains, and required less energy for maintenance than control. Direct and maternal responses were estimated from reciprocal crosses among unselected sires and dams of control and selection lines. Most of the genetic response to selection in all three lines was associated with direct genetic effects, and the highest proportion was from postweaning gain. Indirect responses of carcass characteristics to selection over the 20 yr were increased weight of carcasses that had more lean meat, produced with less feed per unit of gain. At a constant carcass weight, selected lines had 1.32 to 1.85% more retail product and 1.62 to 2.24% less fat trim and 10/100 to 25/100 degrees less marbling than control. At a constant age, heritability of direct and maternal effects and correlations between them were as follows: market weight, 0.36,0.14,and 0.10; carcass weight, 0.26,0.15,and 0.03; longissimus muscle area, 0.33, 0.00, and 0.00; marbling, 0.36, 0.07, and -0.35; fat thickness, 0.41, 0.05, and -0.18; percentage of kidney, pelvic, and heart fat, 0.12, 0.08, and -0.76; percentage of retail product, 0.46, 0.05, and -0.29; retail product weight, 0.44, 0.08, -0.14; and muscle score, 0.37, 0.14, and -0.54. Selection criteria in all lines improved efficiency of postweaning gain and increased the amount of salable lean meat on an age- or weight-constant basis, but carcasses had slightly lower marbling scores.

Our objectives were to determine the ability of a controlled internal drug-releasing device (CIDR, 1.9 g of progesterone), a normal dose of melengestrol acetate (MGA, 0.5 mg(.)cow(-1.)d(-1)), or a high dose of MGA (4.0 mg(.)cow(-1.)d(-1)) to induce ovulation and to eliminate short estrous cycles. Multiparous beef cows (n = 100) were equally assigned to one of four treatments: CIDR, normal MGA, high MGA, or control by age, days postpartum, body condition, and body weight. All cows were fed carrier (0.9072 kg(.)cow(-1.)d(-1)) with (normal MGA, 0.55 mg/kg; high MGA, 4.41 mg/kg) or without MGA for 7 d (d -6 to 0). On d -6, CIDR were inserted and then removed on d 0. Estrous behavior was monitored continuously from d -6 until 29 using HeatWatch electronic mount detectors. Blood was collected on d -13, and three times weekly from d -6 to 29. Treatment influenced (P = 0.03) the percentage of cows that were detected in standing estrus. Beginning on d 2, more CIDR-treated cows had exhibited standing estrus compared with high MGA-treated or control cows, but CIDR- and normal MGA-treated cows did not differ. The percentage of CIDR-treated cows that had ovulated was greater (P < 0.05) than the percentage of normal MGA-treated, high MGA-treated, or control cows beginning on d 4. The percentage of cows that exhibited standing estrus before the first postpartum ovulation (CIDR = 65%, normal MGA = 57%, high MGA = 35%, control = 30%) did not differ (P = 0.09) among treatments. Luteal life span following the first ovulation postpartum and the percentage of cows with a normal luteal life span (i.e., progesterone >1 ng/mL for greater than or equal to10 d) was greater (P < 0.01) in CIDR-treated cows (14.0 +/- 0.8 d; 20/20, 100%) compared with normal MGA-treated (6.2 +/- 1.0 d; 3/13, 23%), high MGA-treated (9.6 +/- 1.0 d; 8/14, 57%), or control cows (6.1 +/- 0.9 d; 4/17, 24%), and greater (P < 0.03) in high MGA-treated cows than in normal MGA-treated or control cows. In the present study, treatment of early postpartum suckled beef cows with CIDR induced ovulation and initiated estrous cycles with a normal luteal life span in more cows than did treatment with MGA. Treatment with MGA (normal or high dose) did not induce ovulation earlier than in control cows, but a high dose of MGA increased the percentage of cows with normal luteal life spans following the first ovulation postpartum.

This paper reports the effect of overexpression of calpastatin on postmortem proteolysis in transgenic mice. Transgenic mice (n = 8) with a human calpastatin gene, whose expression was driven by the human skeletal muscle actin promoter, were killed along with control nontransgenic littermates (n = 5). Hind limbs were removed and stored at 4 degreesC, and muscle samples were dissected at 0, 1, 3, and 7 d postmortem and analyzed individually. At time 0, active human calpastatin was expressed in transgenic murine skeletal muscle at a level 370-fold greater (P < 0.001) than calpastatin in control mice. Although the native isoform of this protein was degraded with storage, at 7 d postmortem, approximately 78% of at-death activity remained, indicating that degraded calpastatin retains activity. Calpain (mu and m-) expression was unaffected (P > 0.05) by the transgene as assessed by immunoreactivity at d 0. Over 7 d, 33% of at-death 80-kDa isoform immunoreactivity of mu-calpain was lost in transgenics compared to an 87% loss in controls, indicating that autolysis of mu-calpain was slowed in transgenic mice. Desmin degradation was also inhibited (P < 0.05) in transgenics when compared to controls. Control mice lost 6, 78, and 91% of at-death native desmin at 1, 3, and 7 d postmortem, respectively; conversely, transgenic mice lost only 1, 3, and 17% at the same times. A similar trend was observed when examining the degradation of troponin-T. Interestingly, m-calpain seemed to undergo autolysis in control mice, which in postmortem tissue is indicative of proteolysis. Further investigation revealed that both Land m-calpain are active postmortem in normal murine skeletal muscle. In conclusion, a high level of expression of active calpastatin was achieved, which, by virtue of its inhibitory specificity, was determined to be directly responsible for a decrease in postmortem proteolysis.

In Exp. 1, 15 noncallipyge and 15 callipyge carcasses were sampled, and Warner-Bratzler shear force (WBSF) was determined for both sides of each carcass at three locations along the length (anterior to posterior) of the LM, whereas slice shear force (SSF) was determined for both sides of each carcass at only one location. For approximately half the carcasses within each genotype, LM chops were cooked for a constant amount of time using a belt grill, and chops of the remaining carcasses were cooked to a constant endpoint temperature using open-hearth electric broilers. Regardless of cooking method and sampling location, repeatability estimates were at least 0.8 for LM WBSF and SSF. For WBSF, repeatability estimates were slightly higher at the anterior location (0.93 to 0.98) than the posterior location (0.88 to 0.90). The difference in repeatability between locations was probably a function of a greater level of variation in shear force at the anterior location. For callipyge LM, WBSF was higher (P < 0.001) at the anterior location than at the middle or posterior locations. For non-callipyge LM, WBSF was lower (P < 0.001) at the anterior location than at the middle or posterior locations. Consequently, the difference in WBSF between callipyge and non-callipyge LM was largest at the anterior location. Experiment 2 was conducted to obtain an estimate of the repeatability of SSF for lamb LM chops cooked with the belt grill using a larger number of animals (n = 87). In Exp. 2, LM chops were obtained from matching locations of both sides of 44 non-callipyge and 43 callipyge carcasses. Chops were cooked with a belt grill and SSF was measured, and repeatability was estimated to be 0.95. Repeatable estimates of lamb LM tenderness can be achieved either by cooking to a constant endpoint temperature with electric broilers or cooking for a constant amount of time with a belt grill. Likewise, repeatable estimates of lamb LM tenderness can be achieved with WBSF or SSF. However, use of belt grill cookery and the SSF technique could decrease time requirements which would decrease research costs.

Data were from 1,379 Composite Gene Combination (CGC; (1)/(2) Red Angus, (1)/(4) Charolais, (1)/(4) Tarentaise) cows born from 1982 through 1999 at the USDA-ARS, Fort Keogh Livestock and Range Research Laboratory, Miles City, MT, and first calving at approximately 2 yr of age. The length of productive life was modeled using Cox regression to identify factors affecting the longevity of beef females. Age at first calving and calf birth weight did not influence longevity. Cows that experienced dystocia were at greater risk of being culled than those that calved without assistance (P < 0.01). On average, as breeding value for cow weight increased, the risk of being culled decreased (P < 0.01), whereas the risk of being culled increased with increasing maternal breeding values for preweaning gain (P < 0.05). Traits measured before 1 yr of age were not useful in predicting the subsequent longevity of cows. The heritability of functional longevity was estimated to be 0.14. Relatively low heritability and the lack of indicators of longevity expressed early in life suggest that genetic improvement of longevity will be difficult. Matching the genetic potential of cows for size and milk production to the production environment such that rebreeding performance is not compromised by concurrent lactation seems to be a consideration in retaining beef females when open cows are culled.

Spatial and temporal relationships between fetal vascular and fat cell development are discussed, including depot- and genetic-dependent arteriolar differentiation. The relationship between connective tissue deposition and elaboration of adipose tissue vasculature is discussed with respect to regulating adipocyte development in a depot-dependent manner. In vitro studies indicated that depot-dependent vascular traits may be attributable to intrinsic growth characteristics of adipose tissue endothelial cells. These studies indicate that adipogenesis may be regulated by factors that drive angiogenesis. Fundamental aspects of angiogenesis, including basement membrane breakdown, vasculogenesis, angiogenic remodeling, vessel stabilization, and vascular permeability were reviewed. Critical angiogenic factors include vascular endothelial growth factor (VEGF), VEGF receptors, angiopoietins (Ang), ephrins, matrix metalloproteinases, and the plasminogen enzymatic system. Vascular endothelial growth factor is the most critical factor because it initiates the formation of immature vessels and disruption of a single VEGF allele leads to embryonic lethality in mice. Expression of VEGF is influenced by hypoxia, insulin, growth factors, and several cytokines. Angiogenic factors secreted and/or produced by adipocytes or preadipocytes are discussed. Vascular endothelial growth factor expression and secretion by adipocytes is regulated by insulin and hypoxia, and is associated with adipose tissue accretion. Vascular endothelial growth factor accounts for most of the angiogenic activity of adipose tissue. The proposed role of leptin as an adipogenic factor is reviewed with respect to efficacy on various aspects of angiogenesis relative to other angiogenic factors. The VEGF and leptin genes are both hypoxia inducible, but potential links between VEGF and leptin gene expression have not been examined. Finally, several studies including a study of mice treated with anti-angiogenic factors indicate that adipose tissue accretion can be controlled through the vasculature per se.

In Exp. 1, we examined perirenal (brown) and sternum s.c. adipose tissue in 14 Wagyu x Angus neonates infused with norepinephrine (NE). Perirenal adipocytes contained numerous large mitochondria with well-differentiated cristae; sternum s.c. adipocytes contained a few, small mitochondria, with poorly developed cristae. Lipogenesis from acetate was high in BAT but barely detectable in sternum s.c. adipose tissue. In Exp. 2, we compared perirenal and tailhead adipose tissues between NE-infused Angus (n = 6) and Brahman (n 7) newborn calves. Brahman BAT contained two-to-three times as many total beta-receptors as Angus BAT. The mitochondrial UCP1:28S rRNA ratio was greater in Brahman BAT than in BAT from Angus calves. Lipogenesis from acetate and glucose again was high, but lipogenesis from palmitate was barely detectable. Tail-head s.c. adipose tissue from both breed types contained adipocytes with distinct brown adipocyte morphology. In Exp. 3, three fetuses of each breed type were taken at 96, 48, 24, 14, and 6 d before expected parturition, and at parturition. Lipogenesis from acetate and glucose in vitro decreased 97% during the last 96 d of gestation in both breed types, whereas the UCP1 gene expression tripled during gestation in both breed types. At birth, palmitate esterification was twice as high in Angus than in Brahman BAT and was at least 100-fold higher than in BAT from NE-infused calves from Exp. 2. Uncoupling protein-1 mRNA was readily detectable in tailhead s.c. adipose tissue in all fetal samples. In Exp. 4, male Brahman and Angus calves (n = 5 to 7 per group) were assigned to 1) newborn treatment (15 h of age), 2) 48 h of warm exposure (22degreesC) starting at 15 h of age, or 3) 48 h of cold exposure (4degreesC) starting at 15 h of age. Brahman BAT adipocytes shrank with cold exposure, whereas Angus BAT adipocytes did not. Similarly, BAT from neonatal lambs (Exp. 5; n = 6 per group) was depleted of lipid in response to cold exposure, although UCP1 gene expression persisted. In Exp. 4, NE stimulated lipogenesis from palmitate in BAT incubated in vitro. Lipogenesis from palmitate was higher in Angus than in Brahman BAT, and increased with both warm and cold exposure. These studies suggest that BAT from Brahman calves may be exhausted of lipid shortly after birth during times of cold exposure. C1 Texas A&M Univ, Dept Anim Sci, College Stn, TX 77843 USA.

Numbers of Campylobacter recovered from carcasses decrease after scalding but increase during feather removal. Mechanical feather picking causes mist as well as particles of dust, feathers, feces, and other matter to become airborne around the machine. This study was conducted to determine if Campylobacter associated with broilers during defeathering can become airborne and contaminate other carcasses in or around a commercial defeathering machine. Carcasses with low numbers of Campylobacter were hung near an operating commercial feather picker where they were exposed to airborne contaminants for 1 min. Low numbers of Campylobacter were detected in the air near the picker. However, microbiological culture of carcasses after exposure to airborne contamination in the picker room revealed that they had no more Campylobacter than unexposed carcasses. These data suggest that airborne contamination does not contribute to the high numbers of Campylobacter routinely found on defeathered carcasses. C1 USDA ARS, Russell Res Ctr, Athens, GA 30604 USA.

Seventy-two percent of the respondents reported using city water to process broilers, and 66% reported discharging to city sewers. Over 41% of the responses were from facilities located in the Southeast; however, there was no relationship between location (region of US) of facility and water use or location of facility and water recycling/reuse. Overall, the average water use prior to implementation of the Hazard Analysis and Critical Control Point (HACCP) was 20.6 L/bird, while the current post-HACCP water usage was reported as 26.0 L/bird. Analysis of data also showed a significant relationship between the amount of water used to process each broiler and the size of the broiler being processed. In addition, over 38% of the respondents reported that they recycle water, and a significant relationship was observed between the amount of water recycled and the size of facility.

Assessments of chick quality are made primarily by subjective observations with few quantitative measurements. Given a better understanding of how broiler breeder hen age and nutrient intake may influence progeny physiology, certain actions can be taken to improve chick quality. This experiment evaluated the effects of broiler breeder age, dietary zinc source, and their interaction on the physiological characteristics of chicks at hatching. Caged broiler breeder hens were provided 1 of 3 diets from hatch through 65 wk of age. All experimental diets consisted of 160 ppm supplemental zinc from inorganic ZnSO4, AvailaZn zinc-amino acid complex (ZnAA) or a mixture of ZnAA and ZnSO4 (ZnAA + ZnSO4, 80 ppm zinc from each). Incubation length, relative organ weights, and carbohydrate status were measured in chicks from hens at 29, 41, 53, and 65 wk of age. The variation in hatch time among eggs set together was not influenced by hen age, but mean incubation length decreased from 29 to 53 wk of age and subsequently increased from 53 to 65 wk. Seasonal temperature changes may have caused confounding effects on incubation length. Chick heart glycogen declined as hens aged, and liver lactate was lowest in progeny from 65-wk-old hens. Relative yolk sac weight and relative heart weight were lowest in progeny from 29-wk-old hens. These data indicate that underdevelopment of supply organs may limit the performance of some chicks from young hens. Supplemental zinc source in breeder hen diets did not influence chick physiology at hatching. C1 Univ Georgia, Dept Poultry Sci, Athens, GA 30602 USA. USDA ARS, Russell Res Ctr, Athens, GA 30605 USA.

The exotic Newcastle disease (END) crisis in the traditional commercial industry led to a related problem for game bird producers due to confusion in defining a game bird, which is also a commercial venture. Time spent planning rather than reacting to situations is often a luxury but must be moved to a higher priority. One example is the Triennial Extension Workshop, which is proposed to become a biennial event. We continue to develop and implement innovative programs based on relevance to animal agriculture and societal requirements. As a team, we have achieved an excellent synergy and impressive results through our cooperation and networking. A special award is provided to an extension person each year to ensure contributions are recognized that might otherwise be overlooked. The Texture Technologies Corporation Support Personnel Award is new this year and recognizes the essential contributions of farm, laboratory, and other personnel. Also, the American Poultry Historical Society (APHS) continues to recognize career contributions to the poultry system through the Hall of Fame.

At the conclusion of the 1999 season, dead lobsters were estimated at 11 million, resulting in a 90-99% reduction of landings in western LIS and failure of the natural lobster fishery. Fishermen described moribund lobsters that were "limp," interpreted clinically as paretic or flaccidly paralyzed. Necropsies were performed on dead or dying limp lobsters, and tissue samples were collected for histopathological, ultrastructural, microbiological, and toxicological analysis. Microbiological cultures of hemolymph and hepatopancreas failed to isolate a bacterium or group of bacteria in any significant frequency or pattern. Toxicological analyses of hepatopancreas and skeletal muscle did not identify significant amounts of trace elements, polycyclic aromatic hydrocarbons, polychlorinated biphenyl congeners, or pesticides. Microscopic analyses of hemocoelomic viscera and nervous tissues revealed a protozoan parasite in foci of hemocytic infiltration of nerves, in cytoplasm of neurons, and between nerve fibers without attendant hemocytic infiltrates as well as in micronodular aggregates of hemocytes in the subcuticular interstitium and tegumental glands. Histologic and ultrastructural features of this parasite were characteristic of protozoa of the genus Paramoeba (Schaudinn, 1896), and contact transmission experiments involving lobsters from uninfected, geographically distant sites and infected lobsters from western LIS resulted in transmission of paramoebiasis. This report represents the first description of a proximate cause of lobster mortality from the 1999 epizootic, along with additional evidence supporting the assertion that this parasitic paramoeba may be the primary cause of the 1999 lobster mass mortality.

This study was conducted to examine the effect of increasing protein intake on urinary calcium excretion and to compare circulating levels of IGF-I and biochemical markers of bone turnover in healthy older men and women who consumed either a high or a low protein food supplement for 9 wk. Thirty-two subjects with usual protein intakes of less than 0.85 g/kg.d were randomly assigned to daily high (0.75 g/kg) or low (0.04 g/kg) protein supplement groups. Isocaloric diets were maintained by advising subjects to reduce their intake of carbohydrates. Selected biochemical measurements were made at baseline and on d 35 and either d 49 or 63. Changes in urinary calcium excretion in the two groups did not differ significantly over the course of the study. The high protein group had significantly higher levels of serum IGF-I ( P = 0.008) and lower levels of urinary N-telopeptide ( P = 0.038) over the period of d 35 - 49 or 63. We conclude that increasing protein intake from 0.78 to 1.55 g/kg.d with meat supplements in combination with reducing carbohydrate intake did not alter urine calcium excretion, but was associated with higher circulating levels of IGF-I, a bone growth factor, and lowered levels of urinary N-telopeptide, a marker of bone resorption. In contrast to the widely held belief that increased protein intake results in calcium wasting, meat supplements, when exchanged isocalorically for carbohydrates, may have a favorable impact on the skeleton in healthy older men and women.

Measured values for EFC, derived from 553 balance studies in middle-aged women (mean age, 48.8 yr), were pooled with 76 values obtained from premenarcheal girls ( mean age, 11.2 yr) after adjusting for differences in body size. The aggregate sample provided values for calcium absorption efficiencies spanning a range from under 10% to over 90%. EFC is known to be inversely related to fractional calcium absorption AbsFx), and the broad range of absorption efficiencies provided by the composite sample allowed derivation of reasonably precise estimates of EFC at 0% and 100% absorption. These were 0.8067 (+/- 0.0143) mg/cm height.d and 0.1799 ( +/- 0.0310) mg/cm height . d, respectively. At 0% absorption, EFC is identical to the total entry of calcium into the intestine from endogenous sources ( secretions plus sloughed mucosa), whereas at 100% absorption, EFC measures only endogenous entry effectively distal to the absorptive surface. The partition described facilitated derivation of a formula to calculate TIC for any paired values of EFC and AbsFx, i.e. TIC = EFC/ [0.223 + 0.777 (1 - AbsFx)].

Using a newly designed computable general equilibrium (CGE) model that differentiates 7 productive activities and 22 age and gender groups, this study compares various options for financing the implicit pension debt and estimates the effects of pension reform on the sustainability of the system and on economic growth. Simulation results show that the current pay-as-you-go system is not financially sustainable and the implicit pension debt is estimated at around 46 to 64 percent of GDP in 2000. The paper proposes to use value-added tax revenue to finance the transition cost, which would make the new multi-pillar system financially sustainable. C1 World Bank, Washington, DC 20433 USA.

Holstein Association USA has registered 2319 ETS and 215 ETN clones. The number of male clones has decreased. Animals selected for cloning were slightly superior genetically to population mean for yield traits. For females, mean superiority of pedigree merit of ETS clones was 186 kg for milk, 9 kg for fat, and 7 kg for protein compared with the population for the same birth year; for ETN clones, superiority to the population was 165, 10, and 8 kg. Advantage in pedigree merit for male clones generally was slightly greater. The small pedigree advantage for female clones of <1 standard deviation above breed mean indicates that selection of animals to clone was not based primarily on yield. Yield deviations were lower for ETS clones than for their full siblings, which indicates a possible impact of the technology on performance. Yields were lower for ETN clones than for their noncloned full siblings, but differences were small and based on small numbers of clones. Milk composition for cloned cows was not different from that for the population. Estimated genetic merit based on daughter yield was more similar for male clone pairs with apparent identical genotype than for clone pairs from the same biotechnology but nonidentical as confirmed by blood typing. For ETS clones with confirmed identical genotypes, identical genetic merit should be assigned. C1 ARS, Anim Improvement Programs Lab, USDA, Beltsville, MD 20705 USA.

The extent of heat treatment affects the quality of the whey protein concentrate, and wide variation in product quality exists due to the various means of manufacture and from the whey product history from farm to factory. The study was carried out with 6 commercial whey protein concentrates with 80% protein (WPC80) to determine variations in physical properties, particle size and density, and functional properties-solubility, gel strength, foam volume, and stability. Significant differences were observed among all the products for every property compared. Particulate size was the most important determinant of functional characteristics. Larger particulate WPC80 had significantly higher fat content and were less soluble with poor foam stability; but narrowing the particle size distribution through sieving, minimized variations. We determined that sieving all products within the particle size distribution range of 100 to 150 microns minimized variation in physical composition, making functionality uniform. WPC80 from different manufacturers can be made to perform uniformly within a narrow functionality range by reducing the particle size distribution through sieving.

This paper presents studies that were conducted to evaluate NH3 emissions from swine finisher and sow animal houses in the southeastern USA. Management and climate variables including animal weight, feed consumption, housing gutter water temperature, total time fans operated per day, house air temperature, house ambient NH3 concentration, and animal numbers were measured to determine their individual and combined effect on NH3 emissions. Ammonia emissions varied on daily and seasonal bases with higher emissions during warmer periods. For finishers, the summertime housing emissions on a per-animal basis were 2.4 times higher than wintertime (7.0 vs. 3.3 g NH3 animal(-1) d(-1)) or 3.2 times higher when compared on an animal unit (AU) basis (1 AU 500 kg) because of climate and animal size differences between measurement periods. For summertime, the emission factor for the finishing pigs was 7.8 times higher than for sows on an animal basis and 25.6 times higher on an AU basis. Simple models were developed for housing emissions based on (i) all measured factors that were independent of each other and (ii) on three commonly measured management factors. The two models explained 97 and 64%, respectively, of variations in emissions. Ammonia emissions were found to be somewhat less than other studies on the same type housing due to more representative housing concentration measurements and calibration of exhaust fans; thus, emission factors for these type houses will be less than previously thought.

Soil collected from the field was amended in the lab with P added as 1% P-H(3)PO(4), biosolids compost added at 10% (referred to hereafter as "compost"), and a high-Fe by-product (referred to hereafter as "Fe") + P-triple superphosphate (TSP) (2.5% Fe + 1% P-TSP) and incubated under laboratory conditions at a constant soil pH. Changes in Pb bioavailability were measured with an in vitro test and a feeding study with weanling rats. Field-amended and incubated soils using these plus additional treatments were evaluated using the in vitro extraction and tall fescue (Festuca arundinacea Schreb. cv. Kentucky-31) metal concentration. Reductions were observed across all parameters but were not consistent. In the feeding study, the 1% P-H(3)PO(4) and compost treatments resulted in a decrease of 26% in rat tissue Pb concentration compared with the control soil. The 2.5% Fe + 1% P-TSP showed a 39% decrease. The 1% P-H(3)PO(4) treatment caused the greatest reduction in in vitro extractable Pb from field samples (pH 2.2) with a measured reduction of 66%, while the compost treatment had a 39% reduction and the 2.5% Fe + 1% P-TSP treatment a 50% reduction. The in vitro extraction (pH 1.5) run on field samples showed no reduction in the compost or Fe treatments. The 1% P-H3PO4 treatment was the most effective at reducing plant Pb, Zn, and Cd.

Estuarine physical transport processes and the episodic nature of herbicide release into surface waters complicate interpretation of water concentration measurements and allocation of sources. Water concentrations of herbicides and two triazine degradation products (CIAT [6-amino-2-chloro-4-isopropylamino-s-triazine] and CEAT [6-amino-2-chloro-4-ethylamino-s-triazinel) were measured in surface water from four sites on 40 d from 4 Apr. through 29 July 1996 in the Patuxent River estuary, part of the Chesapeake Bay system. Atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) was most persistent and present in the highest concentrations (maximum 1.29 mug/L). Metolachlor [2-chloro-6'-ethyl-N-(2-methoxy-1-methyl-ethyl)-o-acetoluidide], CIAT, CEAT, and simazine (1-chloro-3,5-bisethylamino-2,4,6-triazine) were frequently detected with maximum concentration values of 0.61, 1.1, 0.76, and 0.49 mug/L, respectively. A physical transport model was used to interpret atrazine concentrations in the context of estuarine water transport, giving estimates of in situ degradation rates and total transport. The estimated half-life of atrazine in the turbid, shallow upper estuary was t(1/2) = 20 d, but was much longer (t(1/2) = 100 d) in the deeper lower estuary. Although most (93%) atrazine entered the estuary upstream via the river, simulations suggested additional inputs directly to the lower estuary. The total atrazine load to the estuary from 5 April to 15 July was 71 kg with 48% loss by degradation and 31% exported to the Chesapeake Bay. Atrazine persistence in the estuary is directly related to river flows into the estuary. Low flows will increase atrazine residence time in the upper estuary and increase degradation losses.

Experiments were conducted to investigate the effect of various environmental factors on the rate of 1,3-D hydrolysis. Cis-, trans-1,3-D and their isomeric mixture were spiked into water and Arlington soil (coarse-loamy, mixed, thermic Haplic Durixeralfs) and incubated under different conditions. The rate of 1,3-D hydrolysis in water and soil were evaluated based on its residual amount and Cl- release, respectively. 1,3-D hydrolyzed rapidly in deionized water, with a half-life of 9.8 d at 20degreesC. The hydrolysis was pH dependent, with low pH inhibiting and high pH favoring the reaction. Other factors such as isomeric differences, photo irradiation, suspended particles, and small amounts of co-solutes had little effect on the reaction. In soil, 1,3-D hydrolyzed following pseudo first-order kinetics. The hydrolysis rate constant increased with soil moisture content and decreased with the initial 1,3-D concentration. At 20degreesC, >60% of the 1,3-D applied at <0.61 g kg(-1) in 10% moisturized soil hydrolyzed within 30 d. The soil particle size and mineralogy had little effect on the reaction rate. Organic matter promoted 1,3-D degradation via direct substitution reactions, and the trans-isomer showed preference over the cis- to react with certain organic molecules. Microbial contributions were initially insignificant, and became important as soil microorganisms adapted to the fumigant. The results suggest that to accelerate 1,3-D degradation, pH, soil moisture, and organic amendment should be considered. C1 Univ Calif Riverside, Dept Environm Sci, Riverside, CA 92521 USA.

We evaluated the effect of implementing the late spring nitrate test (LSNT) for corn (Zea mays L.) grown within a 400-ha, tile-drained subbasin in central Iowa. Surface water discharge and NO3 concentrations from the treated subbasin and two adjacent subbasins receiving primarily fall-applied, anhydrous ammonia were compared. In two of four years, the LSNT method significantly reduced N fertilizer applications compared with the farmers' standard practices. Average corn yield from LSNT fields and nonlimiting N fertilizer check strips was not significantly different. Autoregressive (AR) models using weekly time series in surface water NO3 concentration differences between the LSNT and control subbasins indicated no consistent significant differences during the pre-LSNT (1992-1996) period. However, by the second year (1998) of the treatment period (1997-2000), NO3 concentrations in surface water from the treated subbasin were significantly lower than the concentrations coming from both control basins. Annual average flow-weighted NO3 concentrations for the last two years (1999-2000) were 11.3 mg N L-1 for the LSNT and subbasin and 16.0 mg N L-1 for the control subbasins. Based on these values and the AR models, widespread adoption of the LSNT program for managing N fertilizer where fall N application is typically practiced could result in a greater than or equal to30% decrease for NO3 concentrations in surface water.

Approaches that are more accurate are needed to improve manure management and reduce nutrient loss to the environment. In this study, we compared direct (N-15 recovery) and indirect (difference method [Diff Meth] and fertilizer equivalence [FE] approach) methods of determining first-year dairy manure N availability or recovery during three cropping seasons. A field experiment was conducted on a Piano silt loam (fine-silty, mixed, superactive, mesic Typic Argiudolls) planted to corn (Zea mays L.). Plots received either manure, fertilizer N, or no N. Microplots receiving N-15-labeled manure were also established each study year. Manure was applied to a new plot each cropping season. Whole-plant N uptake was the best crop parameter to use for FE estimates. Estimates of N availability by relative effectiveness (Rel Eff), which are derived from the Diff Meth, and FE were similar (32 and 41%, respectively) and higher than unlabeled N or N-15 recovery measurements because these indices factor in N use efficiency. Measures of the Rel Eff of manure N use were highly affected by control plot N uptake. The FE approach is less influenced by control plots, but it requires the inclusion of several more treatments and use of mathematical functions to describe crop response to N. These limitations are reflected in the wide ranges obtained for N availability estimates (-60 to 148%). Although apparent N recovery by the Diff Meth (14%) or direct measurements of N-15 recovery (16%) were close on average, variability tended to be much lower for the N-15 method. In addition, the Diff Meth was highly dependent on initial soil conditions. Use of N-15-labeled manure, although more costly and time-consuming, provided more consistent and reliable results.

The objectives of this study were to (i) evaluate NH3 volatilization from composting litter by measuring both NH3 volatilization and changes in total nitrogen (N) in the litter and (ii) evaluate potential methods of reducing NH3 losses from composting poultry litter. Poultry litter was composted for 68 d the first year and 92 d the second year. Eleven treatments were screened in Year 1, which included an unamended control, a microbial mixture, a microbial mixture with 5% alum incorporated into the litter, 5 and 10% alum rates either surface-applied or incorporated, and 1 and 2% phosphoric acid rates either surface-applied or incorporated. Treatments in Year 2 included an unamended control, a microbial mixture, alum (7% by fresh wt.), and phosphoric acid (1.5% by fresh wt.). Alum and phosphoric acid reduced NH3 volatilization from composting poultry litter by as much as 76 and 54%, respectively. The highest NH3 emission rates were from microbial treatments each year. Compost treated with chemical amendments retained more initial N than all other treatments. Due to the cost and N loss associated with composting poultry litter, composting is not economical from an agronomic perspective compared with the use of fresh poultry litter.

We developed a simple approach to predict dissolved P release from manures based on observed trends in laboratory extraction of P in dairy, poultry, and swine manures with water over different water to manure ratios. The approach predicted well dissolved inorganic (R-2 = 0.70) and organic (R-2 = 0.73) P release from manures and composts for data from leaching experiments with simulated rainfall. However, it predicted poorly (R-2 = 0.18) dissolved inorganic P concentrations in runoff from soil boxes where dairy, poultry, and swine manures had been surface-applied and subjected to simulated rainfall. Multiplying predicted runoff P concentrations by the ratio of runoff to rainfall improved the relationship between measured and predicted runoff P concentrations, but runoff P was still overpredicted for dairy and swine manures. We attributed this overprediction to immediate infiltration of dissolved P in the freely draining water of dairy and swine manure slurries upon their application to soils. Further multiplying predicted runoff dissolved inorganic P concentrations by 0.35 for dairy and 0.60 for swine manures resulted in an accurate prediction of dissolved P in runoff (R-2 = 0.71). The ability of our relatively simple approach to predict dissolved inorganic P concentrations in runoff from surface-applied manures indicates its potential to improve water quality models, but field testing of the approach is necessary first.

Inclusion of ethylenediaminetetraacetic acid (EDTA) in the alkaline extraction solution recovered between 82 and 97% of the total P from the three manures, which represented a significant improvement on recovery in NaOH alone. Low concentrations of paramagnetic ions in all manure extracts meant that relatively long delay times (>5 s) were required for quantitative analysis by solution P-31 NMR spectroscopy. The manures contained inorganic orthophosphate, orthophosphate monoesters, orthophosphate diesters, and inorganic polyphosphates, but results were markedly influenced by the concentration of NaOH in the extractant, which affected both spectral resolution and the apparent P composition of the extracts. For example, extraction of swine manure and broiler litter with 0.5 M NaOH + 50 mM EDTA produced remarkable spectral resolution that allowed accurate quantification of the four signals from phytic acid, the major organic P compound in these manures. In contrast, more dilute NaOH concentrations produced considerable line broadening that obscured individual signals in the orthophosphate monoester region of the spectra. Spectral resolution of cattle manure extracts was relatively unaffected by NaOH concentration. Improvements in spectral resolution of more concentrated NaOH extracts were, however, compromised by the disappearance of phospholipids and inorganic polyphosphates, notably in swine and cattle manure extracts, which indicated either degradation or a change in solubility. The optimum extraction conditions will therefore vary depending on the manure type and the objectives of the study. Phytic acid can be accurately quantified in swine manure and broiler litter by extraction with 0.5 M NaOH + 50 mM EDTA, while a more dilute NaOH concentration should be used for complete P characterization or comparison among different manure types.

Trace elements in soil with broiler litter application SO JOURNAL OF ENVIRONMENTAL QUALITY LA English DT Article ID HEAVY-METALS; CADMIUM; COPPER; CARBON; ZINC; LEAD AB An understanding of the long-term cycling of trace elements in soil with broiler litter fertilization under various forage utilization strategies is needed to develop sustainable agricultural production systems. We evaluated differences in Cu, Mn, Zn, and six other trace elements in response to 5 yr of bermudagrass [Cynodon dactylon (L.) Pers.] management varying in fertilization and harvest strategies on a Typic Kanhapludult in Georgia. Chicken (Gallus gallus) broiler litter was a significant source of trace elements that led to 3.4 +/- 0.5 times higher Cu, 2.0 +/- 0.3 times higher Mn, and 2.1 +/- 0.2 times higher Zn in the surface 3 cm of soil than when forage was fertilized inorganically. There were variable effects of broiler liner fertilization on other trace elements, depending upon element, depth of sampling, and forage utilization strategy. Concentrations of all trace elements in soil were below levels considered toxic to plants. Soil at a depth of 0 to 3 cm under grazed paddocks had 33 +/- 5% greater Cd, 18 +/- 1% greater Cr, 53 +/- 24% greater Cu, and 24 +/- 7% greater Zn compared with unharvested and bayed management. Trace elements in soil were unaffected whether forage was unharvested or removed as hay. These results suggest that broiler litter is a significant source of several trace elements and that ruminant processing of forage and subsequent deposition of excreta on the paddock allow these trace elements to accumulate more at the soil surface where they might interact with the high concentration of organic matter.

Cortisol was added to a commercial catfish feed by dissolving in ethanol and spraying the feed to yield a dietary concentration of 150 mg kg(-1) feed. The cortisol diet and the control (no cortisol) diet were offered at a rate of 1% of biomass to three replicate ponds each containing 28 female and 14 male broodfish, respectively, three times per week for I I weeks. Spawning began 10 days after the start of the experiment, and continued for 10 weeks. In fish fed cortisol, body mass and the hepato-somatic index were reduced (P less than or equal to 0.02) and concentrations of plasma cortisol and glucose were significantly higher (P less than or equal to 0.0003) compared to those of controls. The relative frequency of spawning was similar between the two treatments; however, cortisol-fed channel catfish had an average of 47.1% more spawns than the control-fed fish. On average, there were 25.5 spawns per pond in the treated groups compared to 12.3 spawns per control pond (P = 0.10). No effect was observed oil egg production, with individual egg mass, fecundity, and hatching success being similar (P greater than or equal to 0.27) for both treatments. Despite the observed negative effects of cortisol on somatic and hepatic growth, the increased reproductive output coupled with no observable effects on the eggs or hatching success demonstrates that cortisol does not suppress channel catfish reproduction.

Contamination might be introduced into the flesh from the rind by cutting or by contact of cut pieces with contaminated rinds. Our objectives were to investigate the efficacy of hot water or hot 5% hydrogen peroxide treatments in reducing the population of native microflora and inoculated Salmonella on cantaloupe rind and transfer to fresh-cut tissue during cutting. Whole cantaloupes, inoculated with a cocktail of Salmonella serovars to give 4.6 log CFU/cm(2) and stored at 5 or 20degreesC for up to 5 days, were treated with hot water (70 or 97degreesC) or 5% hydrogen peroxide (70degreesC) for 1 min at 0, 1, 3, or 5 days postinoculation. Aerobic mesophilic bacteria and yeast and mold on treated whole melon and fresh-cut pieces were significantly (P < 0.05) reduced by all three treatments. Treatments with hot water (70 and 97degreesC) caused a 2.0- and 3.4-log CFU/cm(2) reduction of Salmonella on whole cantaloupe surfaces irrespective of days of postinoculation storage prior to treatment up to 5 days at 5 or 20degreesC, respectively. Treatment with 5% hydrogen peroxide (70degreesC) caused a 3.8-log CFU/cm(2) reduction of Salmonella. Fresh-cut pieces prepared from untreated inoculated melons and those treated with 70degreesC hot water were positive for Salmonella. However, fresh-cut pieces prepared from inoculated whole melon dipped in water (97degreesC) or hydrogen peroxide (70degreesC) for 60 s were negative for Salmonella, as determined by dilution plating onto agar medium, but were positive after enrichment at days 3 and 5 of storage at 5degreesC. The ability to detect Salmonella in fresh-cut pieces was dependent on the initial level of inoculation. The results of this study indicate that the use of hot water (97degreesC) or heated hydrogen peroxide to reduce the population of Salmonella on contaminated whole cantaloupes will enhance the microbial safety of the fresh-cut product.

Pressurization of phage lambda in buffered media at 300 MPa for 300 min, 350 MPa for 36 min, and 400 MPa for 8 min reduced the titer of phage lambda by 7.5, 6.7, and 7.7 log, respectively. Pressurization of phage lambda in milk at 300 MPa for 400 min, 350 MPa for 80 min, and 400 MPa for 20 min reduced the titer of phage lambda by 5.4, 6.4, and 7.1 log, respectively. Tailing was observed in all inactivation curves, indicating that the linear model was not adequate for describing these curves. Among the three nonlinear models studied, the Weibull and log-logistic models consistently produced best fits to all inactivation curves, and the modified Gompertz model the poorest. Because there were no significant differences in the values of shape factor (n) for suspension medium buffer, we reduced the number of parameters in the Weibull model from two to one by setting n at the mean value. The simplified Weibull model produced a fit comparable to the full model. Additionally, the simplified Weibull model allowed predictions to be made at pressures different from the experimental pressures. Menstruum was found to significantly affect the pressure resistance of phage lambda. Comparison of pressure inactivation of hepatitis A virus and phage lambda indicated that phage lambda is more sensitive to pressure than hepatitis A virus in Dulbecco's modified Eagle medium with 10% fetal bovine sera.

When grown to stationary phase in the absence of glucose and without prior acid exposure, there was a range of responses to a pH challenge of 6 h at pH 2.5. However, populations of 53 of the 59 E. coli isolates examined were reduced by less than 2.00 log CFU/ml, and populations of 24 of these isolates were reduced by less than 1.00 log CFU/ml. In contrast, there was little variation in population reductions when the E. coli were grown with glucose and preadapted to acidic conditions. With few exceptions, acid adaptation improved survival to the acid challenge, with 57 of the 59 isolates exhibiting a log reduction of less than 0.50. Differences in acid resistance or the ability to adapt to acidic conditions between E. coli O157:H7 and non-O157 commensal E. coli were not observed. However, we did find that the E. coli O157 were disposed to greater acid injury after the low pH challenge than the non-O157 E. coli, both for cells that were and were not adapted to acidic conditions before the challenge. The enhancement of low pH survival after acid adaptation that was seen among these recent natural isolates of E. coli O157 further supports the idea that the previous environment of this pathogen should be a consideration when designing microbial safety strategies for foods preserved by low pH and acid.

Apples ('Delicious' and 'Fuji') were repeatedly weighed to determine mass loss. Shrinkage was measured with a strain gauge sensor. 'Delicious' apples lost firmness (73 to 58 N) while 'Fuji' apples maintained firmness at 69 N over 57 days in storage. Apples lost mass at a constant rate with 'Delicious' losing mass slower (0.6% per month) than 'Fuji' (1.1% per month). 'Delicious' apple shrank less (0.28 mm) than the 'Fuji' (0.70 mm) over 57 days. The relationship between firmness and mass loss, or shrinkage was dependent on apple cultivar. Firmness was significantly and linearly related to mass loss and to shrinkage in 'Delicious' apples. It is possible to predict firmness of 'Delicious' apples under RA storage conditions by tracking mass loss or shrinkage. C1 Washington State Univ, Richland, WA 99352 USA.

The enzyme was stable for 24 h at both temperatures but decreased by 45% after 120 h of storage time at 15 degreesC. Isoelectric studies suggest a possible dual lipase and esterase action of the enzyme. Enzymatic activity increased by about 60% when the reaction temperature was increased from 30 degreesC to 40 degreesC and remained constant until 70 degreesC, but the enzyme was unstable when stored at the high temperature. Calcium treatment reduced lipase activity in the fresh-cut fruit. C1 USDA ARS, So Reg Res Ctr, New Orleans, LA 70124 USA.

Soils perform 6 main functions (biomass production, water quality maintenance, biological habitat, physical infrastructure support, raw materials for human use, and maintaining cultural heritage) and a soil is evaluated by its ability to perform one or more of these functions. The ability of the land to feed and clothe people and to maintain ecological functions is being impeded by demographics. The global land area that is generally free of constraints for most agricultural uses is about 12.6%. Agricultural land, however, is unequally spread around the globe with a larger portion in the temperate countries of the world. In addition to poorer land quality in tropical regions, land degradation is also well entrenched, thus aggravating food security. There are 11.9 million km(2) of such lands and about 1.4 billion people are involved and most of these areas are in the developing countries. Countries of the developing parts of the world have to make a conscious decision to better manage their land resources. The paradigm shift that poorer countries need to make to sustain food production is to implement holistic and sustainable land management programs by adopting technologies that have already been validated in other parts of the world.

A. Webb) trees were fertigated with one of five nitrogen (N) concentrations (0, 5. 10, 15, or 20 mM) in a modified Hoagland's solution from July to September. In October, the trees were sprayed twice with either water or 3% urea, then harvested after natural leaf fall and stored at 2degreesC. Trees were destructively sampled during winter storage to determine their concentrations of amino acids, protein, and non-structural carbohydrates (TNC). Increasing N supply either via N fertigation during the growing season or with foliar urea applications in the fall increased the concentrations of both free and total amino acids, but decreased their C/N ratios. Moreover, as the N supply increased, the proportion of nitrogen stored as free amino acids also increased. However, protein was still the main form of N used for storage. The predominant amino acid in both the free and the total amino-acid pools was arginine. Arginine N accounted for an increasing proportion of the total N in both the free and the total amino acids as the nitrogen supply was increased. However, the proportion of arginine N was higher in the free amino acids than in the total amino acids. A negative relationship was found between total amino acid and non-structural carbohydrate concentrations, suggesting that TNC is increasingly used for N assimilation as the supply of nitrogen increases. Urea applications decreased the concentrations of glucose, fructose, and sucrose, but had little influence on concentrations of sorbitol and starch. We conclude that protein is the primary form of storage N, and that arginine is the predominant amino acid. Furthermore, the synthesis of amino acids and proteins comes at the expense of non-structural carbohydrates. C1 Oregon State Univ, Dept Hort, Corvallis, OR 97331 USA.

Seeds were harvested from Ornithogalum thyrsoides hybrid 'Chesapeake Starlight' ('CS') and five seedlings (SD1-SD5) were selected and evaluated for growth and flowering. These seedlings varied in scape length, 9 flower shape and colour, and the presence or absence of pollen. Ornithogalum conicum, Bokbaai type of O. thyrsoides 7050A, 7050B and a seedling from a cross between O. conicum x O. thyrsoides 7050C which were considered as possible paternal parents of the seedlings were also analysed for DNA fingerprinting. A total of 169 random amplified polymorphic DNA (RAPD) bands were produced, of which 90 (53%) were polymorphic. Based on the p-distance value, O. conicum was initially excluded as a potential source of pollen and Bokbaai type of Ornithogalum 7050A, and 7050B was considered to be the most likely pollen source. However, the possibility that all seedlings could result from self-pollinated progenies of 'CS' was not excluded. Five randomly selected primer pairs for amplified fragment length polymorphism (AFLP) analysis generated a total of 298 fragments, of which 191 (63.4%) were polymorphic bands. The presence of marker 109 in all four seedlings, SDI, SD 2, SD 4, and SD 5 and in O. conicum x 7050C suggests that marker 109 was inherited from 7050C. According to the p-distance and nonmaternal band analysis performed with RAPD and AFLP, it was concluded that the seedlings were not the result of self-pollination, and O. thyrsoides 7050C could be the paternal parent. Ornithogalum species such as O. thyrsoides, instead of O. conicum, should be used in future breeding efforts to breed a paper white flower with cup-shaped florets.

This method is expressly tailored to address severe problems typical of incised channels with little sediment coarser than sand. In these types of environments, buoyancy forces are typically more important factors in woody debris stability than fluid drag. Buoyant forces are counteracted by the weight of the structure, earth anchors, and sediment deposits. Design concepts were tested in a demonstration project constructed along 2 km of channel draining a 37-km(2) watershed. Large woody debris structures reduced velocities in the region adjacent to the bank toe and induced sediment deposition and retention. Construction costs per unit channel length were 23-58% of costs for recent stone bank stabilization projects within the same region. During the second year following construction, 31% of the structures failed during high flows, probably due to inadequate anchoring.

Although resistance to amitraz ill B. microplus was previously reported ill several countries, the actual measurement of the level of amitraz resistance ill ticks has been difficult to determine due to the lack of I proper bioassay technique. We conducted a survey, by using a newly reported technique that was a modification of the standard Food and Agriculture Organization larval packet test, to measure the levels of resistance (1.68- to 4.58-fold) was detected in 11 of those strains. Our laboratory selection Using amitraz oil larvae of the Santa Luiza strain, Which originated from Brazil, achieved a resistance ratio of 153.93 at F-6, indicating the potential for high resistance to this acaricide in B. microplus. Both triphenylphosphate and piperonyl butoxide significantly synergized amitraz toxicity in one resistant strains. Target site insensitivity, instead of metabolic detoxification mechanisms, might be responsible for amitraz resistance observed in the Santa Luiza strain and possibly ill other amitraz resistant B. microplus ticks from Mexico. The Santa Luiza strain also demonstrated high resistance to pyrethroids mid moderate resistance to organophosphates. Multiple resistance shown in this strain and other B. microplus strains from Mexico poses I significant challenge to the management of B. microplus resistance to at acaricides ill Mexico.

In a petri dish bioassay, ticks were released within a ring of repellent on a horizontal filter paper disk. In the second bioassay, ticks were allowed to climb a vertical strip of filter paper whose central portion was treated with a repellent. Deet and AI3-37220 were more effective against I. scapularis than A. americanum nymphs. In the petri dish bioassay, none of the concentrations of deet or AI3-37220 tested confined A. americanum. within the treated ring. However, in the vertical bioassay, both species exhibited avoidance of the repellents, and I. scapularis was repelled by much lower concentrations than A. americanum. I. scapularis were repelled by lower concentrations in the vertical bioassay than in the petri dish bioassay. Deet was slightly more effective against I. scapularis than AI3-37220 in both bioassays, but AI3-37220 was significantly more effective than Beet against A. americanum in the vertical bioassay.

The current study sought to devise a simple method for PCR-amplification, cloning, and sequencing of Pasteuria 16S rDNA from small numbers of endoscopes, with no need for prior DNA purification. Results show that DNA extracts from plain glass bead-beating of crude suspensions containing 10,000 endoscopes at 0.2 x 10(6) endoscopes ml(-1) were sufficient for PCR-amplification of Pasteuria 16S rDNA, when used in conjuction with specific primers. These results imply that for P. penetrans and P. nishizawae only one parasitized female of Meloidogyne spp. and Heterodera glycines, respectively, should be sufficient, and as few as eight cadavers of Belonolaimus longicaudatus with an average number of 1,250 endospores of "Candidatus Pasteuria usgae" are needed for PCR-amplification of Pasteuria isolates that have been reported on nematodes and, and consequently, expedite the classification of those isolates through comparative sequence analysis.

LDL particles were characterized by polyacrylamide gradient gel electrophoresis in 36 moderately hypercholesterolemic men and women (LDL cholesterol > 3.36 mmol/L). All subjects consumed in random order each of the four diets (soy protein depleted of isoflavones, soy protein enriched in isoflavones, animal protein with no added isoflavones, and animal protein with added isoflavones) for 6 wk. Consumption of soy protein was associated with a larger LDL peak particle size relative to animal protein (P < 0.01). Soy protein also decreased the cholesterol levels in LDL < 25.5 nm by 12.3% (P < 0.001) and increased cholesterol levels in LDL > 26.0 nm by 14.3% (P < 0.05) relative to animal protein. Isoflavones did not affect these LDL particle characteristics. Soy protein shifted LDL particle distribution to a less atherogenic pattern and this effect is independent of soy's isoflavone component.

However, no data exist concerning their dietary intake. Therefore, PAS in common and infant foods from the U.S. were analyzed. On the bases of our data and those from the USDA's Continuing Survey of Food Intakes by Individuals (CSFII) of 1994-1996, the mean daily intake of PAS in the U.S. population (>2 y old) was estimated to be 57.7 mg/person. Monomers, dimers, trimers, and those above trimers; contribute 7.1, 11.2, 7.8, and 73.9% of total PAS, respectively. The major sources of PAS in the American diet are apples (32.0%), followed by chocolate (17.9%) and grapes (17.8%). The 2- to 5-y-old age group (68.2 mg/person) and men >60 y old (70.8 mg/person) consume more PAS daily than other groups because they consume more fruit. The daily intake of PAS for 4- to 6-mo-old and 6- to 10-mo-old infants was estimated to be 1.3 mg and 26.9 mg, respectively, based on the recommendations of the American Academy of Pediatrics. This study supports the concept that PAS account for a major fraction of the total flavonoids ingested in Western diets. C1 USDA, ARS, Arkansas Childrens Nutr Ctr, Little Rock, AR 72202 USA.

On the other hand, dietary fatty acids play an essential role in brain function. The objectives of this study were to assess the effect of dietary fat type on vitamin C and vitamin E (alpha-and gamma-tocopherol) concentrations in peripheral and brain tissues and its effect on 8-epiPGF(2)alpha (F-2-isoprostanes). Male Golden Syrian hamsters (n = 120, 8 wk old) were fed diets enriched in butter, hydrogenated fat (margarine), and canola and soybean oils. After 12 wk, hamsters were deprived of food, anesthetized with isoflurane, and killed via terminal exsanguination. Analyses of vitamins C, E, and 8-epiPGF(2)alpha were performed in peripheral tissues and brain. Hamsters consuming the margarine-enriched diet had lower (P < 0.05) vitamin C and alpha-tocopherol concentrations in liver, plasma, and brain, and higher (P < 0.02) plasma 8-epiPGF(2)alpha than groups fed the butter, and the canola and soybean oil diets. Liver and plasma gamma-tocopherol concentration was higher (P < 0.001) among the groups fed the soybean- and margarine-enriched diets compared with the other groups. alpha-Tocopherol was higher (P < 0.05) and 8-epiPGF(2)alpha lower (P < 0.01) among the groups fed the canola and soybean oil diets compared with the other groups. Across the groups, an inverse correlation between plasma levels of vitamin C and 8-epiPGF(2)alpha (r = -0.37, P = 0.03) and a positive correlation between plasma levels of vitamin C and alpha-tocopherol were observed (r = 0.341, P = 0.003). Hamsters fed the butter-enriched diet had a higher (P < 0.03) plasma uric acid concentration than the other groups. The results of this study provide new evidence concerning the effect of dietary fat on antioxidant status, which is important for the maintenance of good health.

In the present study, we investigated the effects of BC, beta-apo-14'-carotenoic acid (14'CA), or benzo[a]pyrene (BP; a primary lung carcinogen from cigarette smoke) treatments, either alone or in combination, on cell growth and expression of the retinoic acid receptor (RAR) of normal human bronchial epithelial (NHBE) cells. We found that both BC and 14'CA inhibited the growth of NHBE cells (P < 0.05) with or without BP. The level of RARbeta, a tumor suppressor, but not RARalpha or RARgamma, was reduced by 50% in the NHBE cells treated with BP. However, treatment with either BC or 14'CA significantly induced the expression of RARbeta in the NHBE cells, and prevented the reduction of RARbeta by BP. Furthermore, 14'CA transactivated the RARbeta promoter primarily via its conversion to retinoic acid (RA). In the presence of 3-mercaptopropionic acid, an inhibitor of fatty acid oxidation, both RA formation and transactivation activity from 14'CA were decreased. These observations indicate that the growth inhibitory effects of BC and beta-apo-carotenoic acid are through their conversion to RA and upregulation of RARbeta.

However, the exact nature of the interactions between selenium and copper is not fully understood. In this study, the effect of copper on the cell cycle arrest induced by selenite or selenocystine was examined. Both selenite and selenocystine were effective in inhibition of cell growth and cell cycle progression. Cell cycle analysis revealed that selenite (3-5 mumol/L) caused a decrease in GI phase cells that corresponded with an increase in S and G2 phase cells, and that 0.625 or 1.25 mumol/L copper sufficiently inhibited selenite-induced cell cycle arrest. In contrast, selenocystine caused an increase in GI phase cells that corresponded with a decrease in S and G2 phase cells. Interestingly, 0.625 or 1.25 mumoUL copper did not inhibit selenocystine-induced cell cycle arrest. In addition, cell free get shift assay demonstrated that selenite suppressed the inhibitory effect of copper on SP-1 DNA binding. Furthermore, although 5 mumol/L selenite in culture media significantly increased the intracellular selenium content, 1.25 mumol/L copper sulfate blocked this increase of the intracellular selenium content. Collectively, these data demonstrate that selenite and selenocystine cause cell cycle arrest via distinct mechanisms, and suggest that copper may interact with selenite extracellularly, which represents the basis of antagonism between copper sulfate and selenite.

Identification of this virus was based on host range, properties in crude sap, transmissibility, and serological tests. PNRSV-J has a limited range of experimental hosts. The dilution end-point of infectivity was 10(-2), the thermal inactivation point was 57degreesC, and purified virus had an in vitro longevity of 16 h at 25degreesC. PNRSV-J was detected by double antibody sandwich-enzyme linked immunosorbent assay (DAS-ELISA). PNRSV-J was purified from cucumber leaves harvested 6-8 days after inoculation. The modified purification method gave an adequate virus yield for antibody production. Antiserum produced by immunizing a rabbit had a titer of 1024 in direct antigen coating (DAC)-ELISA, with high specificity to PNRSV. An immunocapture-reverse transcription-polymerase chain reaction (IC-RT-PCR) protocol was useful for the detection of PNRSV in herbaceous and woody plant tissues. Nucleotide sequence and phylogenetic analysis of RT-PCR products derived from RNA3 of PNRSV-J confirmed its identity as an isolate of PNRSV and revealed that it is a member of Group I (PV32) isolates.

The general management paradigm is that plant production declines as stocking rate increases. Our objective was to determine the impact of stocking rate on herbaceous production of a sand sagebrush (Artemisia filifolia Torr.)-grassland. Stocking rates averaging 43, 57, and 85 animal-unitdays ha(-1) (AUD ha(-1)) for year-round grazing were applied from 1941 to 1961. Herbaceous plant production was determined by sampling standing crop in temporary exclosures at the end of the growing season from 1958 to 1961, the last 4 years of the grazing study. Total herbaceous production averaged over stocking rates and years was 1,490 kg ha(-1). Grasses contributed 89 % of the total while forbs contributed 11 %. Total production averaged 1,540, 1,470, and 1,450 kg ha-1 for stocking rates of 43, 57, and 85 AUD ha(-1) y(-1), respectively. There were no differences among stocking rates for total production or for the production of any individual grass species (P > 0.05). Forb production was also not affected by stocking rate, averaging 200, 140, and 120 kg ha-1 for stocking rates of 43, 57, and 85 AUD ha(-1) y(-1) (P > 0.05). Differences in production among years were much greater than differences among stocking rates for all vegetation components. Little bluestern [Schizachyrium scoparium (Michx.) Nash] and sand lovegrass [Eragrostis trichodes (Nutt.) Wood] showed the greatest responses to favorable precipitation. Herbaceous production of this sand sagebrush-grassland was little affected by 20 years of differential stocking rates. C1 ARS, So Plains Range Res Stn, USDA, Woodward, OK 73801 USA.

Yosemite is a designated wilderness, to be managed such that its natural conditions are preserved. Studies were conducted in 3 characteristic meadow types: shorthair sedge (Carex filifolia Nutt.), Brewer's reed grass (Calamagrostis breweri Thurber), and tufted hairgrass [Deschampsia cespitosa (L.) Beauv]. Horses and mules grazed experimental plots at intensities of 15 to 69% utilization for 4 seasons. In all 3 meadows, grazing caused decreases in productivity. The mean reduction after 4 years of grazing was 18% in the shorthair sedge meadow, 17% in the Brewer's reed grass meadow, and 22% in the tufted hairgrass meadow. Grazing also caused shifts in basal groundcover (usually a reduction in vegetation cover and increase in bare soil cover), and changes in species composition. Productivity and vegetation cover decreased as percent utilization increased, while bare soil cover increased as utilization increased. Changes in species composition were less predictably related to differences in grazing intensity. Passive management of grazing is insufficient in wilderness areas that are regularly used by groups with recreational stock. Wilderness managers need to monitor meadow conditions and the grazing intensities that occur. Our study suggests that biomass and ground cover are more sensitive indicators of grazing impact than species composition. Managers must make decisions about maximum acceptable levels of grazing impact and then develop guidelines for maximum use levels, based on data such as ours that relates grazing intensity to meadow response.

SO JOURNAL OF RANGE MANAGEMENT LA English DT Article DE Purshia tridentata; livestock; big game; winter range; wildlife; habitat; browse ID CRESTED WHEATGRASS; EASTERN OREGON; PRECIPITATION; MANAGEMENT; RANGE; DEER AB Due to its palatability and forage quality, antelope bitterbrush (Purshia tridentata Pursh DC) is a desirable shrub across western US rangelands. Because little information is available regarding grazing management of young bitterbrush, a study was undertaken to explore stocking pressure thresholds and quantify effects of light and heavy spring cattle grazing on shrub growth. Rates of browsing and trampling and forage availability were monitored over 3 years in southeast Oregon. Across years, 29% of bitterbrush endured trampling in light-grazing treatments, and 55% experienced trampling under heavy grazing. Linear models relating time and cattle density successfully explained (r(2) = 0.84-0.86) probabilities of bitterbrush being trampled. Forage utilization averaged 32% and 59% in lightly and heavily grazed units, and 14 and 62% of bitterbrush were browsed in lightly and heavily-grazed pastures, respectively. Cattle began browsing when herbaceous standing crop declined to 100-150 kg ha(-1). Browsing in heavily-grazed pastures reduced diameters of bitterbrush by 4.5 to 9.5 cm in 1998 and 1999, but shrub height was unaffected. Lightly-grazed stands exhibited a 50% greater increase in bitterbrush diameter, 30% greater height increment, and 8% longer twigs than shrubs in ungrazed pastures. At the end of the 1997 and 1998 growing seasons, bitterbrush in heavily-grazed pastures were 11 cm greater in diameter than ungrazed controls and equal to shrubs in lightly-grazed pastures. To stimulate bitterbrush growth, young stands can be lightly-grazed (30 to 40% utilization of herbaceous forage) by cattle when bitterbrush is flowering and accompanying grasses are in vegetative to late-boot stages of phenology.

However, the magnitude of the problem is unknown because presently only nationwide and state estimates of food insecurity are available. Purpose: This study was conducted by the Lower Mississippi Delta Nutrition Intervention Research Consortium to determine the prevalence of household food insecurity, identify high-risk subgroups in the Lower Delta, and compare to national data. Methods: A 2-stage stratified cluster sample representative of the population in 36 counties in the Lower Delta was selected using list-assisted random digit dialing telephone methodology. A cross-sectional telephone survey of 1662 households was conducted in 18 of the 36 counties using the US Food Security Survey Module. Findings: Twenty-one percent of Lower Delta households were food insecure, double the 2000 nationwide rate of 10.5%. Within the Lower Delta, groups with the highest rates of food insecurity were households with income below $15,000, black households, and households with children. The prevalence of hunger in Delta households with white children was 3.2% and in households with black children was 11.0%, compared to nationwide estimates of 0.3% and 1.6%. Conclusions: The Lower Mississippi Delta is characterized by a high prevalence of food insecurity and hunger. Future efforts to identify the household and community determinants of food insecurity to reduce its high prevalence are indicated. C1 USDA ARS, Delta NIRI, Little Rock, AR USA.
