TY - JOUR T1 - STRATEGIES FOR COLONIZATION AND MAINTENANCE OF THE MEDITERRANEAN FRUIT FLY AN - 902345427; 14664299 AB - Colonies of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) were established from field-collected pupae and reared for 12 generations (G) using 3 different methods; given special care (C). eased from special care into mass rearing (E), and forced directly into mass rearing (F). The respective average numbers of viable pupae per [female] increased from 1.5, 1.7, and 2.0 at G1 to 6.3, 6.6, and 8.5 at G12. The number of viable eggs per fertile [female], though varying greatly depending on generation, never had an increasing or decreasing trend. Thus, since the fertility of individual [female] [female] remained relatively constant, improved yields were primarily due to an increase in the proportion of reproducing females. Furthermore, switching the E colony to the F regimen after G5 was as detrimental as initial colonization.Original Abstract: Strategies de colonisation et d'entretien deCeratitis capitata Des souches de Ceratitis capitata ont ete formees a partir de pupes recoltees dans la nature et elevees pendant 12 generations (G) suivant 3 methodes differentes: avec soins particuliers (C) soins particuliers pendant 5 generations puis tranfert sur regime et substrat artificiel en elevage de masse (E), elevage de masse continu sur regime et substrat artificiel (F). Les nombres moyens de pupes viables par femelle ont augmente respectivement de 1.5, 1.7, et 2.0 and G1 a 6.3. 6.6 et 8.5 en G12. Les nombres d'oeufs viables par femelle feconde ont varie beaucoup suivant les generations sans aucune tendence marquee. Ainsi, puisque la fecondite par femelle est restee relativement constante, l'augmentation de la production est parvenue avant tout de l'augmentation de la proportion de femelles fecondes. Par ailleurs, le transfert de la souche E en regime F apres G5 a eu des effets aussi negatifs que la colonisation initiale.

AN - 15571444; 418347 AB - European corn borer larvae, Ostrinia nubilalis (Hubner), were reared in the field and/or laboratory for 0 to 184 generations (up to 17 years) without diapausing. In 1981, the cultures were reared under both nondiapause- and diapause-inducing conditions. Genes controlling diapause evidently were not selectively removed from the cultures because expression of diapause reoccurred when larvae were reared under diapause-inducing conditions. Rather, the diapausing gene or genes were not expressed when the larvae were reared under nondiapausing conditions. JF - IOWA STATE J. RES.

AN - 15559352; 429462 AB - Samples of segregation 3 farmer stock peanuts from 1980 southeastern United States growing season were analyzed for the presence of cyclopiazonic acid and aflatoxins. Cyclopiazonic acid appeared in 21 of 27 loose-shell kernel fractions at a range of 32 to 6,525 mu g/kg and in 4 of 21 sound mature kernel fractions at a range of 32 to 130 mu g/kg. Aflatoxins were detected in 26 of 27 loose-shell kernel fractions and in 20 of 21 sound mature kernel fractions. Cyclopiazonic acid used at 105 and 210 mu g/kg to spike peanut samples was recovered at an average rate of 93.3%, with ranges of 89 to 119 and 166 to 221 mu g/kg, respectively.

AN - 15538663; 416796 AB - Tarsonemus mites phoretic on southern pine beetles (Dendroctonus frontalis ) were shown to be hypervectors of bluestain fungus, C. minor . Beetles with phoretic mites had significantly more C. minor than did mite-free beetles. Over 90% of tarsonemid mites collected from beetle-infested inner bark and 59% of mites phoretic on emerging beetles carried C. minor spores. This association is an interesting example of a three-way mutualism among insects, mites and fungi. JF - Ecological Entomology AU - Bridges, J R AU - Moser, J C AD - USDA For.

AN - 14017328; 847004 AB - Lactating cattle were treated with ( super(44)C) 4-chlorophenyl methyl sulfide (CPMS) or its ( super(14)C) sulfone analog (CPMSO sub(2)) as a single oral dose equivalent to 10.0 mg/kg b.w. Both compounds were absorbed through the gastrointestinal tract, CPMS was rapidly oxidized to CPMSO sub(2) in the CPMS-treated cow, but CPMSO sub(2) was quite resistant to further metabolism and it was excreted slowly by the kidneys. Thus, CPMSO sub(2) tended to circulate within the body and, after four days, was distributed more-or-less equally throughout the tissues of the body. Oral treatment of sheep with ( super(14)C) CPMSO sub(2) confirmed that the compound is slowly eliminated from the body of ruminants.

AN - 13930927; 778871 AB - Natural aflatoxin contamination of developing corn (Zea mays L.) kernels was studied in one synthetic and 19 hybrids that varied in endosperm and other characteristics. The genotypes were grown at nine diverse locations in the USA in 1980 and 1981. The highest mean aflatoxin level was detected in kernels of Mo17 x B73. Elevated toxin accumulations were also observed in a waxy hybrid. A normal endosperm bybrid (SC54 x SC76) and a synthetic (MoSQA(H)C6) had the lowest mean toxin levels. From 90 to 100% of the samples from the South and 2 to 25% of the Corn Belt samples were aflatoxin positive. Elevated toxin concentrations were associated with a high toxin incidence. However, some locations provided numerous, contaminated samples with relatively low levels of aflatoxin. Elevated aflatoxin levels were also associated with increased insect damage.

Optimized ligninolytic cultures produce super(14)CO sub(2). The rate of CO sub(2) production increased with increasing lignin concentration through 1 mg/mg protein, the highest rate exceeding 8 mu g of lignin/h/mg protein. The lignin underwent a degradation-dependent binding to the mycelium, and was gradually released on continued incubation. Random depolymerization of the lignin occurred simultaneously with its oxidation to CO sub(2). JF - Holzforschung AU - Chua, MGS AU - Choi, S AU - Kirk, T K AD - For. Products Lab., For.

Whole papaya fruits, Carica sp., infested in the laboratory by the oriental fruit fly, Dacus dorsalis Hendel, were exposed to the parasite in the field. The flies and parasites in the fruits were reared through to adults in the laboratory. The simplicity of the method required only the labor of one person to collect large numbers of B. oophilus of uniform age. In addition, the method can be used as a survey tool to collect other species of parasites and to determine spatial and seasonal distribution in the field.

AN - 13905490; 756649 AB - Early in the development of the biological control of weeds programs in the United States, an advisory group was established at the request of biological control researchers who were seeking (1) advice on potential conflicts of interest (i.e., on whether or not plants targeted for study were universally regarded as "weeds"), and (2) recommendations regarding plants against which exotic phytophagous arthropods (i.e., plant-feeding insects and mites) proposed for introduction into the United States should be tested. This group was established in December 1957, first as a subcommittee, and later as the Working Group on Biological Control of Weeds (WGBCW) under the Weed Committees of the USDA and U.S. Department of the Interior (USDI), that meet jointly. Since its establishment, the Working Group has broadened its responsibilities to include not only response to questions concerning conflicts of interest and selection of test plants, but also evaluation of the adequacy of the data showing the safety of - and the need for - the release of exotic organisms for control of weeds.

AN - 13904651; 747301 AB - The attempt to control floating alligatorweed (Alternathera philoxeroides ) in the southeastern United States with an imported Argentine flea beetle (Agasicles hydrophila ) is often cited as a successful example of the biological control of an aquatic weed in the United States. This is true in most waterways in Florida and other warm areas in the Southest, but in the colder areas, alligatorweed has not been controlled. In February 1979, while surveying in South America for natural enemies of noctuid moths, the senior author collected alligatorweed flea beetles from near Mar del Plata, Argentina, which is the southernmost, or coldest, limit of the beetles in the southeastern United States are reported in this paper.

Host eggs were ranked by decreasing percentages of parasitization as follows: E. elutella > E. cautella > E. figulilella > A. kueehniella > P. interpunctella . Differences in percent parasitization were not significant between Ephestia spp., but A. kueehniella and P. interpunctella were parasitized significantly less often. Average percentage egg hatch after exposure to Trichogramma ranged from 5.0 to 9.3%, except for Plodia where it averaged 33.3%. It appears that inundative releases of Trichogramma into commodity storage could play an important role in suppression of stored-product moth populations.

AN - 13881572; 737649 AB - The effects of environmental conditions during sunflower (Helianthus annuus L.) seed development and maturation on the final oil content of seed and composition of the oil have been studied extensively in commercial sunflower, but very little is known about the wild sunflower (H. annuus L.). A better understanding of these changes could lead to a greater utilization of wild sunflower in breeding programs. The objective of this study was to determine the influence of genotype, flowering date, and environment on oil content and oil quality of maturing wild sunflower. Oil content and linoleic acid concentration differed significantly in seeds of the original population vs. the seeds grown at a single location. Sibbed and open-pollinated seeds did not differ in total oil content when grown at a single location, but linoleic acid did. Oleic acid concentrations of sibbed and open-pollinated seeds of populations grown at a single location did not differ significantly from the seeds of the original populations.

AN - 13880072; 737017 AB - Two cycles of recurrent selection for grain protein percentage were evaluated, and direct response in grain protein percentage and correlated responses for other traits were determined. Ten hard red spring wheats selected for grain protein percentage and other traits were intermated to form the initial population (CO). Selection for grain protein percentage was applied on F sub(3) lines in C0 and C1, and 20 to 25 lines were selected for intercrossing to initiate the next cycle. The proportion of each population selected for C1 and C2 were 7.5 and 4% respectively. Recurrent selection was effective in increasing grain protein percentage in this population, and thus could be used in germplasm development. Multiple trait selection or selection for correlated traits might result in gains in grain protein percentage while maintaining grain yields.

As much as 33% of hemicellulose per dry weight of the plant material could be obtained by treating the plant biomass with 5-10% NaOH for 1 hour at 121 C or for 24 hours at room temperature. Growth of the organism on plant hemicellulose yielded glucose isomerase (2.2 units/ml culture) and xylanase (27 units/ml culture). The levels of the enzymes produced on hemicellulose were about the same as on xylose or xylan. The organism, however, grew poorly on sugarcane bagasse and produced little enzymes.

Trees of both species injected with 50 percent ethanol experienced greater attack by A. bilineatus and had more tissue necrosis up the stem than trees in the other treatments. A. mellea colonized roots of both oak species that were injected with 20 or 50 percent ethanol, and colonization was greater in trees injected with 50 percent ethanol. These trees also were severely attacked by A. bilineatus , exhibited dieback 1 year after injection, and showed premature autumn color.

Germination occurred on moderately and severely burned seedbeds but not on scorched and lightly burned surfaces. Seedling survival occurred almost exclusively on severely burned surfaces.

AN - 13846526; 708271 AB - Different aged trees of singleleaf pinyon (Pinus monophylla Torr. and Frem.) provided a chronosequence of undergrowth response to increasing tree dominance. Undergrowth composition and distribution around the tree stem changed as trees increased in size. Tree-induced microhabitats created a mosaic of undergrowth species groups each with their own sere. Succession was more a plant-by-plant process than a species population phenomena, as plants of the same species were enhanced or debilitated during the same time period depending on the plants' position relative to the tree crown. Existing undergrowth reorganized itself to occupy the evolving tree-induced microhabitats rather than new microhabitats being occupied by invader species. JF - BULL. TORREY BOT. CLUB.

AN - 13844936; 707771 AB - Seven units (about 2 ha each) of black spruce--feather moss forest were experimentally burned over a range of fuel moisture conditions during the summer of 1978. For the first 3 years after fire, biomass production was greater on heavily burned than on lightly burned sites (58 vs. 37 g/m super(2) on an annual basis). Heavily burned sites were completely dominated by the invading species Epilobium angustifolium, Ceratodon purpureus), and Marchantia polymorpha , whereas lightly burned plots were occupied by sprouting species such as Calamagrostis canadensis, Vaccinium uliginosum , abd Ledum groenlandicum . Soil pH and amounts of total P and available P in the forest floor increased significantly as a result of burning; and in all cases, increases reached a maximum in moderately and heavily bruned areas. Total N in the forest floor increased significantly in moderately burned, but decreased slightly in heavily burned areas. JF - CAN. J. FOR. RES. AU - Dyrness, C T AU - Norum, R A AD - Inst. North.

AN - 13844513; 707500 AB - Vegetation, forest productivity, and soils of 23 forest stands in the taiga of interior Alaska are described. The stands are arranged on an environmental gradient from an aspen (Populus tremuloides ) stand on a dry, steep south-facing bluff, to open black spruce (Picea mariana ) stands underlain by permafrost on north-facing slopes. The coldest site is a mixed white spruce (iPicea glauca ) and black spruce woodland at the treeline. A black spruce stand on permafrost has the lowest tree standing crop (1586 g multiplied by m super(-2)) and annual productivity (56 g multiplied by m super(-2) multiplied by year super(-1)) whereas a mature white spruce stand has the largest tree standing crop (24,577 g multiplied by m super(-2)) and an annual productivity of 540 g multiplied by m super(-2) multiplied by year super(-1), but the successional balsam popular stand on flood plain alluvium has the highest annual tree increment (952 g multiplied by m super(-2) multiplied by year super(-1)). The study supports the hypothesis that black spruce is a nutrient poor, unproductive forest type and that its low productivity is primarily the result of low soil temperature and high soil moisture.

AN - 13839120; 695477 AB - In experimental plantings of slash pine (Pinus elliottii ) that incurred numerous rust (Cronartium quercuum ) infections in the second, fourth, and fifth seasons of growth, tall seedlings and saplings became infected more frequently than short ones in the second and fifth seasons. In the fourth season, short trees became infected as often as tall ones, indicating that infection is not solely dependent on the quantity of tissue or number of shoots produced during a growing season. After trees became infected, their heights decreased relative to trees not infected. Magnitude of decrease was greatest in trees that incurred infections of main stems (versus branches) in the first 2 years. Decrease was directly related also to the degree of encirclement of the main stem by rust and to the development of witches'-brooms. Decrease in relative height preceded rust associated mortality. Differences between sizes of infected and healthy trees several years after infection occurs are unreliable indicators of rust's impact on growth unless initial tree size and timing of all mortality are considered.

At 4-week intervals during a 20-week period after planting, seedlings were excavated to determine the pattern of lateral root egress and spread of Pisolithus ectomycorrhizae on laterals. Between 75 and 80 percent of the laterals egressed from the bottom of the plugs in both fumigated and nonfumigated soil. Hyphal strands of Pisolithus spread from the plugs and developed ectomycorrhizae at greater distances from the plugs on lateral roots of seedlings in fumigated soil than on seedlings in nonfumigated soil. The results indicated that root configuration of container-grown loblolly seedlings initially influences lateral root egress (first 20 weeks) after planting.

Partial conversion of the riparian forest to cropland was projected to increase NO sub(3)-N and NH sub(4)-N loads by up to 800%. Total replacement of riparian forest with crops would increase loads of all nutrients studied except organic N, DMRP, and total P. Land managers can maintain the nutrient filtering capacity of the streamside forest by selective harvesting of hardwoods and by maintaining the present hydrologic regime.

AN - 13815823; 677275 AB - Growth of Douglas-fir infected by Phellinus (Poria) weirii was evaluated. Each of the 171 trees in a 40-year-old stand was mapped, felled, and examined. Annual volume growth was calculated from measurements of 10 or more cross sections per stem. Two approaches were used to compare actual with expected growth of diseased trees: (1) A regression equation, developed from healthy tree data, was used to estimate expected growth of diseased trees; and (2) healthy and diseased trees were paired on the basis of similar growth before disease, and continuing growth of the healthy tree was taken as the expected value. Both approaches gave similar results. JF - Forest Science AU - Thies, W G AD - For. Sci. Lab., USDA For. Serv., Pacific Northwest For. and Range Exp.

AN - 13810704; 660527 AB - Soil and nutrient export were monitored before and after two prescribed burns 18 months apart. Burns were designed to prepare Piedmont pine stands for regeneration. The burns did not significantly affect storm runoff, sediment concentrations, or sediment export from the watersheds. Both runoff and sediment export increased from one watershed, but the effect was due to a bark beetle outbreak rather than to prescribed burning. Analysis showed no significant change in NO sub(3)-N, NH sub(4)-N, Ca, Mg, or K concentrations or export after either burn. Sodium concentration before burning was significantly different for the burned-unburned watershed pairs but not significant after either prescribed burn.

AN - 13796081; 656877 AB - Field tests showed that 3 components of the Heliothis virescens sex pheromone when deployed individually, significantly disrupt pheromone communication of males of this species and of H. zea . Field and wind tunnel tests indicated that males of H. zea are attracted to and mate with the females of H. virescens when the atmosphere is permeated with (Z)-9-tetradecenal or (Z)-11-hexadecen-1-o1. This mating is fatal to both individuals because of morphological incompatibility of their genitalia. Habituation of H. zea males to these compounds is the most likely reason for this attraction between 2 species that show reproductive isolation in nature. JF - Experientia.

AN - 13792024; 660034 AB - Agriculture uses about 84 percent of the developed water supply in California. The U.S. Water Resources Council projects an 11.7 percent increase in total water use for California between 1975 and 2000. Nonagricultural uses are expected to increase by 52.3 percent during this same period. Very few would question that, during the remainder of this century, heavy pressures will be exerted on California's water supply. The possibility of conserving and redirecting the use of existing water supplies has been proposed as at least a partial solution to this problem. The author's purpose here is to give some estimates of the amount of irrigation water that could be voluntarily conserved and made available for reuse in the San Joaquin Valley.

This study was initiated to determine the genetics of sugarbeet root cell size and sucrose concentration and their inheritance relationships. The significant negative correlation between cell diameter and sucrose concentration and their apparently similar inheritance patterns suggest that the additive genes affecting cell diameter (cell size) may be the same genes responsible for the additive genetic variance of sucrose concentration.

For embryo germination and seedling growth the cultured embryos were transferred to a liquid medium. Embryos were successfully excised and cultured 3 to 7 days after pollination. Fifty-three combinations of species have been hybridized using this system, including 21 which have not been reported using conventional methods.

AN - 13781270; 641301 AB - Growth and developmental characteristics of first and second cycle doubled haploids were compared with those of highly inbred plants of five burley tobacco (Nicotiana tabacum L.) cultivars. When averaged across cultivars, doubled haploids flowered later and developed smaller plants that produced less cured leaf with lower alkaloid content than did the inbreds. Haploids and doubled haploids offer an excellent means to obtain tobacco lines with modified chemical and morphological features. Some mutations may occur in the process, and utilization of doubled haploids should involve confirmation of the characteristics of each line before using it in physiological investigations or in plant breeding.

AN - 13776894; 641972 AB - A trial with 49 entries of alfalfa, Medicago sativa L., was evaluated for total season yield under two harvest managements for 3 years at two sites. Data from the trial series formed a base for which methods of analysis of genotype X environment interaction for perennial forage crops were compared. The methods of analysis included: a) routine multifactor analysis of variance, b) linear regression of individual entry means and c) an orthogonal contrast analysis. The author concluded that the orthogonal contrast analysis was easier to interpret than regression on environmental means for analysis of genotype X environment interactions in perennial crops such as alfalfa.

AN - 13775586; 640058 AB - Seasonal distribution and abundance, habitat preferences and use, and host relationships of Brown-headed Cowbirds (Molothrus ater ) in the Sierra Nevada of California were studied in the Sierra National Forest in 1980 and 1981. Cowbirds strongly prefer meadow edges as breeding habitats, using clearcuts and incompletely logged forests to some extent and unlogged forests rarely or not at all. In the preferred meadow habitats, cowbird abundance declined rapidly with increasing distance from human-based sources of food, such as pack stations. The relative abundance of Warbling Vireos (Vireo gilvus ) was negatively correlated with that of cowbirds. Because cowbirds are rare in or absent from many major habitat types and areas remote from human-based sources of supplemental food, however, it is doubted that any species in the Sierra Nevada is currently threatened by cowbird parasitism.

AN - 13775334; 641773 AB - This study describes a major gene which controls lipoxygenase-3 (L-3) activity in soybean (Glycine max (L.) Merr.). Cultivars "Wasenatsu" (PI 417 458) and "Ichigowase" (PI205 085) were found to lack L-3 by both immunological and electrophoretic methods. The inheritance of this trait was determined from progeny of crosses between Wasenatsu and either "Century" or "Raiden", two cultivars that contain high levels of L-3. Segregation ratios in F sub(2) and F sub(3) seeds from selfed plants indicated that absence of L-3 was due to a single allele that was recessive to the one controlling the presence of the enzyme. The authors propose that the dominant allele be called Lx sub(3), whereas the recessive one be designated lx sub(3).

AN - 13759416; 630674 AB - Three mutants were isolated from ethyl-methanesulfonate-treated B. thuringiensis subsp. israelensis ONR-60A strain. Under an electron microscope, the parent strain and one of three mutants, il069-3, appeared to produce at least two distinct crystal sizes. The il042-8 mutant showed only small crystals, and no crystals were seen in the il069-9 mutant. Bioassay revealed that the parent strain and il069-3 had high mosquitocidal activity, but il042-8 and il069-9 appeared to be nontoxic to mosquito larvae. When crystal proteins were extracted in NaOH at pH 10 with 2% 2-mercaptoethanol (NaOH-MeEtOH) and analyzed by two-dimensional electrophoresis, the parent strain showed a complex protein composition in a molecular weight range of 10,000-120,000. Both the parent strain and the il069-3 mutant produced 28- and 38-kilodalton (kdal) proteins as major components. The results from protein analysis and bioassay strongly indicate that the toxicity is associated with the 28-kdal protein.

Later, two different types of trap (Jackson, and 3HB) were compared for effectiveness in luring or attracting the Sesiidae. Smaller numbers of adult clearwing moths and larger numbers of other lepidoptera were attracted to the baits dispensed from 3HB traps compared to Jackson traps. Over 5500 adult Sesiidae were trapped that season. JF - J. ENVIRON. SCI. HEALTH, PART A. AU - Adler, V E AD - Biol. Active Nat. Prod. Lab., Agric. Res.

AN - 13746214; 616400 AB - Three species of phoretic Sphaeroceridae kleptoparasitize the dung caches of scarab beetles in north Florida. Ceroptera sivinskii Marshall intercepts beetles under dung, then accompanies them into their burrows. Borborillus frigipennis (Spuler) rides on ball rolling and tunnelling scarabs. It perches on beetles both underground and in flight. B. singularis (Spuler) is similar in habits but is principally nocturnal. Kleptoparasitism is probably a means of escaping environmental decay and competition in "parent" faeces. Nonscarab competitors and predators are less abundant in beetle stored dung, and Borborillus spp. are among the few spaerocerids that flourish when large, rapidly developing calypterate flies are abundant. Since oviposition in B. frigipennis occurs only underground, phoresy is an inexpensive and safe means to maintain contact with hosts. Males ride in order to find mates.

Titers of all six strains grown in defined medium LD82 reached 2.0 x 10 super(9) to 6.0 x 10 super(9) CFU/ml of culture. All spiroplasma strains tested formed colonies readily on agar medium LD82. None of the spiroplasmas formed typical fried-egg colonies. All formed diffuse colonies, but the forms of colonies differed somewhat among the spiroplasma strains. In preliminary studies of nutritional requirements, phospholipids slightly enhanced the growth of the epiphytic and insect-pathogenic strains in medium LD82 and were found essential for good growth of S. citri).

V. The impact of sequential releases of sterilised tsetse flies. AN - 13705359; 582361 AB - A field trial of the sterile insect technique was conducted in Tanzania using irradiated males of Glossina morsitans morsitans Westw. at an experimentalsite 110 km to the south of Tanga. Following two applications of endosulfan as an aerosol at an interval of 28 days, irradiated puparia of G. m. morsitans were released twice weekly at stations distributed throughout the experimental site. Over the 15-month experimental period, an average of 81% control of G. m. morsitans was obtained, whereas G. pallidipes Aust., against which no releases were carried out, recovered to prespray levels within five months. The released sterile insects were found to be highly competitive and to survive well in the field.

II. Analyses of increasing photosynthesis, specific leaf weight and longevity of leaves in cotton. AN - 13700958; 572655 AB - The model GOSSYM was used to demonstrate how a computerized crop simulation model can be used in a breeding or agronomic research program to simulate the performances of genotypes with different physiological response when grown under various environmental conditions. Results of simulating a cotton (Gossypium hirsutum L.) crop with higher leaf photosynthetic rate indicated that cotton lint yield could be increased up to 54% by increasing photosynthetic rate by 30%, providing that adequate N and water were available. This seems to be a more promising characteristic to be used as criteria in a breeding or agronomic research program oriented toward increasing lint yield.

Ineffective nodules that formed on genotypes MnAg(In) and MnSa(In) were similar to effective nodules in early development. However, these nodules had smaller bacteroids and senesced much more rapidly than effective nodules. In contrast, nodules that formed on ineffective genotypes MnNC-3226(In) and MnNC-3811(In) were tumorlike and had few infection threads and bacteroids, and host cells were filled with starch. Nodules from plant-determined ineffective genotypes had reduced glutamine synthetase, glutamate synthase, phosphoenolpyruvate carboxylase, and nodule soluble protein which compared with effective nodules.

AN - 13695135; 573331 AB - Evaporation measurements from "screened" and standard Class A pans at two locations near Fresno, California were compared together and with "potential evapotranspiration" estimates, using two combination equations with climate data from the sites. The screen covering on a Class A pan reduced the Class A pan evaporation by 10%. This difference was found to be due more to radiation than aerodynamic differences. The combination equation calculations were found to be highly correlated with pan evaporation. Pan coefficients of 0.81 and 0.91 were found for the open and "screened" Class A pans, respectively, in the semi-arid climate. JF - AGRIC. METEOROL.

AN - 13684821; 566039 AB - Replicate, 200-g kernel samples were acquired from 26 corn (Zea mays L.) hybrids of the 1980 South Carolina yield to study the interrelaionships between moisture at harvest, bright greenish-yellow (BGY) fluorescence, and aflatoxin concentrations. Ground samples from all of the test hybrids contained some BGY-fluorescing particles, and > 90% of them contained aflatoxin. Although an elevated toxin level was only detected in kernels of a single hybrid, results based on the averages of hybrids in three hybrid maturity groups (short-, mid-, and full-season) showed that kernels of the short-season hybrids contained elevated levels of moisture, BGY fluorescence, and aflatoxin. Variation in moisture levels apparently was related to staggered planting dates of the three maturity groups to facilitate flowering at about the same time. Regression analyses showed significant associations between kernel moisture. BGY fluorescence, and afloatoxin. The results were considered in the context of development of rapid techniques for assessment of regional, preharvest aflatoxin contamination of corn.

AN - 13684090; 552593 AB - Surface runoff (SRO) and shallow-subsurface flow (SSF) from a small, upland, Coastal Plain watershed underlain by plinthite were monitored for a 10-y period. The major water runoff loss from the system was found to be subsurface flow, accounting for 79% of total runoff loss, which occurred primarily from December through May. Nitrate-N concentrations in surface runoff and subsurface flow were relatively uniform over the period, averaging 0.47 and 8.75 mg/L, respectively. The combination of high volume of subsurface flow and its relatively high NO sub(3)-N content, resulted in 99% of total NO sub(3)-N loss via subsurface flow. Predictive equations for monthly surface and subsurface water runoff losses from this watershed were developed using multiple linear regression.

Desorption under all experimental conditions examined resulted in apparent hysteresis. However, the observed hysteresis may have partially resulted from the use of the batch equilibration method to conduct the desroption studies. Each desorption equilibration step apparently altered the physical and/or chemical properties of the soil-solution system in which the desorption occurred, compared with those in which the original pesticide-soil-solution adsorption equilibrium was evaluated.

AN - 13678669; 552587 AB - Nitrogen balance studies in pastures have shown unexplained losses of applied N with much of the losss assumed to be denitrification and NH sub(3) volatilization. This project studied soil, plant, and microclimate effects on diurnal and seasonal fluctuations of gaseous NH sub(3) flux in a subtropical pasture fertilized with urea. Soil and microclimate measurements were taken concurrently with NH sub(3) flux density determinations to relate these factors to magnitude and direction of NH sub(3) transport. Average daily NH sub(3) volatization varied with seasonal soil and microclimate conditions and time after area application. A short period of large NH sub(3) efflux was observed after urea application during warmer seasons whereas smaller efflux for longer duration was observed during cooler seasons. Soil water content and rainfall after urea application modified seasonal NH sub(3) losses. Diurnal NH sub(3) cycling was apparent, with large efflux occurring during daytime and small efflux or influx at night.

Effect of indigenous salinity. AN - 13677706; 547435 AB - To determine the effects of indigenous salinity on rates of compost decomposition and nitrogen transformations, a sewage sludge-wood-chip compost was leached with water. The initial rate of CO sub(2) evolution from the soil amended with leached compost lagged behind that of the soil amended with unleached compost. However, after 33 d of incubation, the leached compost treatments mineralized C at a faster rate, and after 160 d had evolved 14 and 32% more CO sub(2) for the 112 and 224 t ha super(-1) rates, respectively. The total cumulative compost C evolved as CO sub(2) from the unleached and leached compost mixtures after 160 d of incubation were about the same, i.e., 14% and 16%, respectively. However, the amounts of net N mineralized in the unleached and leached systems were greatly different. Results indicate that salts and other compounds that are present in sewage sludge compost (water soluble) can inhibit compost decomposition when added to soil, and enhanced decomposition results in more immobilization of mineral N when these inhibitory compounds are removed by leaching.

AN - 13673989; 552390 AB - Sugar maple (Acer saccharum ) seeds were collected from populations spaced along two altitudinal gradients in the White Mountains of New Hampshire. Sugar maple is a long-lived (200-300 yr) species with continuous distribution, but adaptive adjustment along the altitudinal gradient has occurred in only 8,000 yr, the time since colonization of the White Mountains in the wake of glacial melting. Photosynthesis was highest in progeny from high-altitude populations, representing the species' ecological margin. High-altitude populations also had the lowest specific leaf weight (SLW) the ratio of leaf weight to leaf area, providing a highly cost-effective photosynthetic system, probably the result of natural selection in a short growing season. Respiration rates were also highest in populations native to high altitudes and constitute the cost of maintaining the photosynthetic machinery at high capacity. Photosynthesis tended toward a minimum and SLW to a maximum at mid-elevations. JF - American Journal of Botany AU - Ledig, F T AU - Korbobo AD - Inst. For. Genet., Pacific Southwest For. & Range Exp.

AN - 13673764; 552131 AB - Experiments were conducted with a simulated rainfall on boxes of three different soils (Ruston fine sandy loam, Ruston loam, and Parsons clay), prewetted with a bromide (4,000 ppm Br) solution. The bottom of the soil boxes (100 cm long by 15 cm wide by 10 cm deep) was either an impervious plate that allowed no downward infiltration through the soil during the rainfall, a pervious plate that allowed free infiltration, or a pervious plate covered with a thin layer of soil-slurry, which allowed infiltration at a reduced level. In all the soils, Br concentrations in runoff from impervious-base boxes were one to two orders of magnitude higher than in runoff from pervious-base boxes. Results suggest that clay-pan soils, wet areas in a watershed, and tillage practices that increase permeability of the soil surface layer relative to that of the layer below will greatly increase the loss of soil chemicals to runoff.

Tests were confined to an alfalfa field with a 3-year history of E. phytonomi in developing alfalfa weevil populations. Seven treatment blocks, each of which received one application of Kocide (2.24 kg/ha in 187 liters of water), were sampled weekly for the incidence of E. phytonomi in weevil larvae. No differences in the incidence of E. phytonomi occurred between the Kocide-treated plots and the control plots. Mortality rates among weevil larvae collected from the treated and untreated plots ranged from 83 to 98%. These results indicate that the use of the fungicide Kocide at recommended application rates would not inhibit the expression of E. phytonomi in larval populations of the alfalfa weevil.

AN - 13647133; 529248 AB - Average daily rates of grasshopper survival were inversely related to density. For a hypothetical population of Melanoplus sanguinipes (F.), average survival rates of about 0.95 to 0.96 per day resulted in relatively unifrom populations between generations; rates slightly above or below that range lead to drastic increases or decreases, respectively. There are resonable combinations of daily survival rates and daily feeding rates that will allow any developmental stage within a generation of grasshoppers in the field to dominate utilization of forage by that generation. It is most probable, however, that the first three nymphal instars will be responsible for about 15 to 20% of the total forage utilization, and that adults will be responsible for both the greatest daily rate and the greatest proportion of utilization. Utilization by a nymphal instar is likely to exceed that of adults only under conditions of catastrophic population collapse.

AN - 13641303; 527497 AB - The degradation of super(14)C-malathion ((1,2- super(14)C) ethyl label) was investigated in stored corn and wheat inoculated with A. glaucus , a common grain storage fungus. Grains free of internal storage fungi were surface-sterilized before treatment with super(14)C-malathion and fungal inoculation. After 6 months, inoculated corn contained 74.1 plus or minus 2.6% of applied radiocarbon, compared with 91.9 plus or minus 5.5% in sterilized controls. Similarly, inoculated wheat contained 86.0 plus or minus 2.1% of applied radiocarbon, compared with 92.8 plus or minus 1.1% in sterilized control wheat. The low quantities of radiocarbon recovered from the inoculated grain may have resulted from losses by volatilization or super(14)CO sub(2) evolution, neither of which was determined in this study. Although malathion was degraded in both sterilized and inoculated grain (4 to 18% of the applied radiocarbon was recovered as super(14)C-malathion), sterilized grain contained significantly more super(14)C-malathion than inoculated grain after 6 months.

AN - 13633315; 512038 AB - The pattern of emergence from overwintering (OW) of the tobacco budworm (TBW), Heliothis virescens (F.), was studied in central Texas in 1978-1979 and 1979-1980. Emergence of OW TBW which were collected as larvae in the fall and held in plastic cups in outdoor cages occurred earlier in the spring of 1980 than the spring of 1979. Emergence of OW TBW in the spring of 1980 under natural field conditions occurred later than that observed for the insects held in the outdoor cages. Field studies indicated that caging of the study plots in the fall significantly delayed the emergence of OW TBW compared with areas caged in the spring. Skunks, Mephitis mephitis L., were verified to be predators of Heliothis spp. prepupae and pupae. Meadowlarks, Stunella spp., apparently also prey on OW Heliothis spp. pupae.

AN - 13632867; 529084 AB - A generalized life cycle and biology of the morphs are described for Brachycolus asparagi Mordvilko. Oviparae laid overwintering eggs on the asparagus ferns, Asparagus officinalis L., beginning in September. The eggs hatched in late March and developed into fundatrices that establish themselves on the emerging asparagus spears. A fundatrix gives birth to about 18 nymphs, as compared with 54 nymphs for an apterous virginopara. In summer, the apterous morph had a 33.5% higher intrinsic rate of increase than the alate morph. Crowding of nymphal asparagus aphids increased wing production. The fecundity curve for the apterous virginoparae peaked once, early in their reproductive phase, whereas the curve for the alate virginoparae peaked a number of times and showed that their reproductive phase spanned most of their adult life. A single sexupara could give birth to oviparae, as well as to male and virginoparous morphs. JF - Environmental Entomology AU - Tamaki, G AU - Gefre, JA AU - Halfhill, JE AD - Yakima Agric. Res.

AN - 13632847; 527742 AB - Xylose is a major constituent of hardwood and agricultural residues. Its effective utilization is essential to the economic practicability of any process seeking to use these materials for chemical production. A yeast, Pachysolen tannophilus , has been shown to ferment xylose to ethanol, acetic acid and xylitol, but the rate is slow and yields of ethanol are low. Growth on NO sub(3) super(-) is known to stimulate synthesis of pentose phosphate pathway enzymes, and these studies showed that NO sub(3) super(-) stimulates the aerobic production of ethanol from xylose by Pachysolen). Anaerobic production of ethanol, however, was inhibited by NO sub(3) super(-). Inhibition required induction by growth on NO sub(3) super(-), and inhibition was repressed by NH sub(4) super(+), indicating that nitrate reductase might be involved. Growth rates and product ratios were affected significantly by the nitrogen source used. These results suggest that selection for NO sub(3) super(-) utilization could be a useful screen in the development of yeast strains with improved ability to ferment xylose.

Extension of developmental time increased parasitism by R. lymantriae Watanabe, which prefers 2nd instars less than 5 days old. However L. dispar larvae fed on B. thuringiensis diet yielded significantly fewer female R. lymantriae than those fed only diet; B. thuringiensis reduced L. dispar larval size and prompted ovipositing R. lymantriae to deposit more unfertilized eggs. Use of a sublethal dose of B. thuringiensis for initial establishment of R. lymantriae and its effect on the level of parasitization of gypsy moth are discussed.

AN - 13630533; 527477 AB - Alfalfa (Medicago sativa L.) forage production is usually limited by a collection of pests. Consequently, alfalfa cultivars need multiple pest resistance (MPR). Crossing alfalfa strains with different types of pest resistances, each with a dominant type inheritance, should result in populations with economic levels of resistance to the combined pests. Fourteen strain cross populations were produced at Beltsville, Md. and Reno, Nev. and increased to the Syn 3 or Syn 4 generation. Evaluations of the Syn 1 to Syn 4 generations of six of the populations were made for resistance to anthracnose, bacterial wilt, common leafspot, rust, root-knot nematode, stem nematode, pea aphid, spotted alfalfa aphid, potato leafhopper yellowing, and for fall dormancy ratings. In most cases the pest resistance and dormancy ratings of the six strain cross populations evaluated were near the mean of the parental strains. Forage yields of all 14 populations averaged 108% of the mean of the parent strains and 102% of the best parent. There was a trend for populations with low yielding parents to be lower yielding than populations with high yielding parents. The use of strain crosses to produce MPR populations and cultivars with improved field performance appears to be a promising plant breeding method for alfalfa breeders.

All materials, with the exception of homomenthyl salicylate and 2-hydroxy-4-methoxybenzophenone, at least doubled viral persistence. All p-aminobenzoic acid compounds enhanced persistence 2.2 to 2.6-fold, whereas benzilidine sulfonic acid enhanced persistence 3.6-fold at a 5% concentration. Excellent results were obtained with benzilidine sulfonic acid, whether diet or red oak seedlings were used as the test substrates. A high positive correlation existed between UV B absorbance (280 to 320 nm) and UV protection among the water soluble sunscreens.

AN - 13624941; 498130 AB - Twenty-four colonies, established from 3-lb (ca. 1.4-kg) packages of Italian bees, were divided into two groups of 12 colonies each. Twelve colonies were exposed to Sevin (50w) at a rate of 2.5 lb (AI) per acre (2.5 kg/ha) on 8 July 1981. Twelve colonies were moved to a second apiary the day before spraying. The 12 colonies exposed to carbaryl survived the spray, but a significant number of dead bees were counted daily for 7 days after the spray treatment. After 7 days the mortality was normal. Overall, the total amount of brood reared to the sealed stage was not significantly different, as determined by a three-way analysis of variance. However, immediately after the spray, the pollen substitute-fed colonies reared significantly more brood than unfed colonies. The carbaryl-treated and untreated colonies yielded similar amounts of honey, indicating that the loss of several thousand foraging bees did not have a long-range effect on the colonies.

Four entomopathogenic fungi, Metarrhizium anisopliae, Beauveria bassiana, Paecilomyces lilacinus , and Aspergillus ochraceous , and two entomogenous nematodes, Neoaplectana carpocapsae Weiser and Heterorhabditis sp. Poinar, were found active in the soil and infectious to D. abbreviatus larvae throughout the year. Fungus-infected larvae were most prevalent from May through July, whereas nematode parasitism was most predominant from May through November.

AN - 13622096; 496995 AB - In the southeastern Coastal Plains determinate soybean (Glycine max ) is grown on soils with low water-holding capacities and N contents. Therefore, N fixation and management of water are important in soybean production. Several studies were conducted to increase the understanding of the interaction of these two factors on soybean growth and yield. Experiments were conducted in 1976, 1978, 1979 on a Norfolk loamy sand (Typic Paleudult) with soybean of maturity groups VI, VII, and VIII grown under irrigated and nonirrigated conditions each year with soil water monitored to 60-cm depths. The results show that water management affects soybean N accumulation, distribution, and yield and that R. japonicum strain 110 may intensify or diminish the impact of water regimes on determinate soybean growth and yield.

Part I. Sampling procedures and conditions and descriptions of samples. AN - 13621559; 504021 AB - To aid in the prevention of mine accidents, timber framing must be regularly inspected for decay. It is necessary to first develop a means of assessing the condition of timbers and determining their strengths. From 18 coal mines in Pennsylvania, West Virginia, Illinois, Alabama, Utah, and Colorado 430 timbers were removed for sampling. Timbers were predominantly oaks, maples, sweetgum, southern pines, and lodgepine. They were generally round and non-preservative treated and still retained their bark or remnants of it. White rot predominated in hardwood timbers collected in Illinois, Alabama, and West Virginia. In the Pennsylvania mines a rather even distribution of white and brown rot was evidenced; many timbers contained mixtures of white and brown rot. In softwood timbers from all mines only brown rot was visible. JF - Forest Products Journal AU - Eslyn, W E AD - USDA For. Serv., For. Prod. Lab., P.O.

AN - 13620790; 503839 AB - Contamination of grain sorghum, Sorghum bicolor (L.), with aflatoxin or zearalenone, was previously considered strictly a postharvest problem in grain improperly dried and stored. Samples of preharvest grain from 64 grain sorghum fields in the Georgia coastal plain in 1980 and 1981, however, demonstrated a 56% incidence of aflatoxin contamination ranging in levels from 1 to 90 ppb. In addition, 31% of the grain samples were contaminated with levels of zearalenone ranging from 2 to 1,468 ppb. These findings confirm the presence of mycotoxins in grain sorghum maturing in the fields. A 1981 survey of 15 fields in the Mississippi Delta found no detectable levels of aflatoxin or zearalenone. The data suggest that, although mycotoxins are present in samples of preharvest grain sorghum, the problem may not be as severe as in preharvest corn, Zea mays L., produced in the southeast. The relatively high incidence of field contamination, however, may result in elevated levels of mycotoxins during storage of this grain. Growers and animal producers, therefore, should monitor closely the grain sorghum to be used for feed.

AN - 13611911; 502494 AB - A range of nonoutbreak densities of the Douglas-fir tussock moth, Orgyia pseudotsugata (McDunnough), were analyzed for 11 generations at four geographic locations. Simple correlation analyses of transformed data showed that, of the variation in early larval density, 69% was contributed by the density of early instars in the previous generation and 85% by late instars. In an alternate representation, 52% of the variation in intergeneration trend was contributed by the survival rate of larvae, even though survival was a poor predictor of trends in decreasing populations. For these data, a relatively high rate of larval survival is a good indicator of rapidly increasing populations; however, a causal mechanism is not identified.

AN - 13611472; 502240 AB - The toxicity of nine insecticides to a stem weevil, Cylindrocopturus adspersus (Le Conte), was evaluated in the field to determine differential susceptibility between the pest and its natural enemies. Significant differences were found in the toxicity of six chemicals to C. adspersus , with the organophosphates performing better as a group than the carbamates. The most effective materials were carbofuran and fenitrothion. Inconsistent results were evident in the comparison of parasitization rates, with two chemicals having a higher percent parasitism than the control. The materials that were most toxic to the stem weevil larvae were also the most toxic to the natural enemies. Weevil larvae in carbofuran-treated stems had the lowest percent parasitization. The effect of insecticides on nontarget organisms needs to be considered in the development of management strategies.

Linear regression indicated dispersal of 3.05 to 3.66 m in the release row and 2.45 to 3.05 m across rows. At the higher egg levels, dispersal across rows was also indicated as up to 3.66 m. However, 72% of the damage occurred within a smaller area, 1.83 m (three rows) wide and 3.66 m long. This confirms general observations of damage in the field and has implications for sampling.

AN - 13609391; 502148 AB - In one set of trials, predaceous birds and ants were excluded from trees containing cohorts of the western spruce budworm, (Choristoneura occidentalis ). Birds and ants contributed about 29% of the killing power (K) during the budworm generation, and about 76% between instar IV and adults. Except at high budworm densities, birds compensated for ants on trees protected from ants, and vice versa. In other trials, predaceous birds and small mammals were excluded from gypsy moth (Lymantria dispar ) cohorts. Birds and small mammals contributed about 27% of the killing power during the gypsy moth generation, and about 47% between instar V and adults. In this life system, small mammals compensated for birds, but not the converse. In both life systems, other factors did not compensate effectively in places protected from both predator groups. These results emphasize the need to consider possible compensatory interactions among mortality-causing processes in evaluating any given life system.

AN - 13608334; 502278 AB - Mineral stresses of toxicity or deficiency in plants are not always clearly identifiable entities. They are often the results of complex interactions among the major toxic ions involved, other ions, environmental factors, and the species or genotype of the plant. The ultimate expression of a given "problem soil syndrome" is determined by the plant genotype and its interaction with the environment. Problems of mineral stress can be reduced or prevented by modifying the soil to fit a given plant or by selecting or breeding plant genotypes with greater tolerance to stress. This paper reviews knowledge concerning the physiology of differential plant tolerance to mineral stress, with emphasis on Al and Mn toxicities in acid soils and Fe unavailability in neutral and alkaline soils.

AN - 13582183; 470081 AB - Distributions of nymphs and spittle masses in an old-field alfalfa stand during the nymph development period are described. Taylor's power law provides reliable descriptive parameters for nymph and mass distribution. Iwao's mean crowsdedness-mean density function was less reliable, but adequate to indicate the ecological processes affecting these distributions. Analyses indicated that numbers of nymphs per mass and masses per plant increased during numphal development. Patchiness of these factors also increased. There was no evidence that infested plants became less attractive to nymphs even at densities which causes significnat nutrient loss. In fact, these plants may be more attractive due to a more closed canopy. JF - Environmental Entomology AU - Mangan, R L AU - Wutz, A AD - USDA-ARS Screworm Res., P.O.

AN - 13579694; 469933 AB - A distinct distribution pattern for the Mediterranean fruit fly, C. capitata (Widemann), on the island of Kauai, Hawaii, was determined from trap and fruit infestation data. C. capitata was found at upper elevations as expected. However, it was also found breeding in low-elevation localities along the coast and in major valleys of western Kauai. Traps in areas that receive little rainfall consistently caught higher numbers of C. capitata than those in areas that receive abundant rainfall. Hosts were generally abundant in ecotone areas between dry and wet habitats. The most importants hsots were coffee, Coffea arabica L., strawberry guava, Psidium cattleianum Sabine, and peach, Prunus persica (L.) Batsch. There was evidence that C. capitata moved from these areas into certain dry areas. Generally, populations of C. capitata were absent from large areas of native forest except where the alien strawberry guava had invaded.

AN - 13537765; 435743 AB - Dissolved nutrients were monitored bi-weekly in stream water draining 14 upland watersheds in Oregon's Coast Range after spraying with 2,4,5-T + 2,4-D, clearcut harvesting and slash burning. Anion generation and leaching were primarily studied. The nitrate concentrations fell and the bicarbonate concentrations rose during summer low-flows from treated watersheds without detectable increases in loss of macronutrients (N, Ca, Mg, K, Na). The stream water concentrations of bicarbonate (the most prevalent anion) related to watershed orientation and the degree of devegetation. Nitrate concentrations appeared to be correlated positively with watershed drainage rates. Studies with incubated soils and field sampling of soil solution indicate that denitrification probably minimizes nitrate loss from saturated soils during frequent winter to spring storm periods.

Pump irrigators can reduce energy costs by irrigating more efficiently. U.S. farmers increased onfarm pump irrigation by 21 percent from 1974 to 1980, adding 7.5 million pump-irrigated acres. Farmers irrigated 42.6 million acres in 1980 with onfarm pumps, and pump energy accounted for 23 percent of total energy used onfarm for crop production. Most irrigation pumps used electricity, followed in descending order by natural gas, diesel, liquefied petroleum gas (LPG), and gasoline. Diesel fuel use about doubled, but the use of gasoline and LPG for pumping irrigation water declined. Pump irrigators can reduce energy costs by irrigating more efficiently. Tail-water recovery for surface-water irrigation systems is becoming very popular and can reduce energy use by 10 to 30 percent. Also, low-pressure center pivot sprinkler systems saved United States farmers an estimated $42 million in energy costs during 1980.

Laboratory Determined Hydraulic Conductivities of Some Slowly Permeable Horizons AN - 18961356; 8303781 AB - A comparison was made between saturated hydraulic conductivity values obtained from the piezometer method and results of the laboratory core method for several soils in the flatwoods region of southeast Florida. The piezometer method was used to measure saturated hydraulic conductivities of spodic and argillic horizons in 15 soils. Textures of argillic horizons in these soils range from sandy loam to sandy clay loam. Spodic horizons in these soils range from sand to loamy sand. There was very poor correlation between hydraulic conductivity values derived from core measurements and those obtained with the piezometer method. This suggests the presence of random variation in addition to the obvious bias. Spodic horizons, based on core data, were placed in moderate and moderately rapid classes except for the Ankona, which was placed in the moderately slow class. Results of the piezometer method indicate that all should be in the very slow class except the Myakka and Pendarvis, which should be classified as moderate and moderately slow, respectively. While a general trend was noted among argillic horizons, the individual data points were widely scattered, and the correlation between hydraulic conductivity and consistence is poor. It was concluded that the core method of measuring saturated hydraulic conductivity consistently gave larger values than the piezometer method. The magnitude of the difference in results obtained using the two methods varied from two to over 700-fold. The core method gave hydraulic conductivity values that are too large when used in the design of water control systems.

The ACP project is one of 21 projects selected nationwide to accelerate conservation practices and develop techniques to improve water quality. The project area in Hall County has an excess of nitrate-nitrogen (NO3-N) in the groundwater. The purpose of the special water quality project was to assist farm operators in carrying out recommended practices and techniques to reduce NO3-N levels in groundwater caused by nitrate leaching. Results of the survey showed that two-thirds of the farm operators indicated that high nitrate concentrations in the ground water were a problem. While three operators in four indicated a need to reduce the leaching of nitrates, only half of the sample agreed that irrigation contributed to the problem. Over 70% of the operators used nitrate management practices and 81% followed recommended nitrogen fertilizer application rates. There was a high level of awareness (91%) of the ACP Special Water Quality Project, and about 75% of the operators reported receiving the project newsletter.

Therefore, efforts to obtain water conservation through reduced per acre applications are not likely to be economical in many of these areas. With low cost water, less efficient flood and siphon irrigation systems predominate. In areas with higher water costs , more efficient gated pipe and sprinkler systems are the most common. Nearly 80% of the water provided by the Bureau of Reclamation costs $15 per acre-foot or less. A restructuring of these contractual water prices would encourage farm operations to invest in more water conserving practices and shift from irrigated forage to irrigated food crops and feed grains.

Both the base period land use estimates and the projected land use changes in a sample of 40 projects in two contrasting geographical regions were found to be reliable. When observed land use changes are measured from aerial photographs, the differences between projected and observed land use changes were not statistically significant. Four alternative land use projection techniques - aerial photography, trend analysis, cooperative river basin study procedures and the Markov process - did not improve upon the reliability of the U.S. Department of Agriculture Soil Conservation Service (SCS) land use projections. The SCS land use projection procedures for small watershed areas are set forth in the Economics Guide. Farm surveys are used to collect land use data for planning and evaluation of small watershed projects. The SCS land use projection procedures provide reliable measures of land use trends for estimating land use benefits due to project measures.

An economic analysis of these production functions provides useful information for making farm-level irrigation decisions to increase profits and conserve water in the Ogallala Aquifer. Results of this study show that irrigators can both save water and increase profits for corn by applying water to maximize profits rather than yields when water prices (costs) are high. Profit maximizing quantities of irrigation water change very little in response to changes in crop or water prices, under conventional delivery and application efficiencies. Increasing irrigation application efficiency decreases water pumped at all water prices, while crop profits are only affected at medium and high water prices. A reduction in well yields of up to 20% has no significant effect on crop profits per acre for corn and wheat, assuming normal precipitation. Profit maximization with well yield reductions of 40% or less will result in lower irrigation application levels and not less land under irrigation, assuming normal precipitation.

The production functions show tht short run profits are sharply increased if irrigation field efficiences are increased. Education efforts to reduce irrigation levels will be profitable where the cost of water is medium or high; profits can be increased and water saved if water is medium or high; profts can be increased and water saved if water applications are cut below common practice or the yield maximizing levels. The magnitude of cost savings varies widely based on the source of surface water and the lift depth of pumped water. Educational and management services can encourage farmers to improve field and delivery efficiencies by providing technical and economic data which shows the profitability of efficiency improvement. Improved delivery efficiencies show substantial increases in short run profits in areas of medium to high water prices. The production functions can determine the profit reduction from a 10 or 20% cut in water applications on crops. When very low water prices are increased several fold, water application is reduced by a meaningful amount.

As a result the project was modified to minimize environmental impacts. Work started in November 1978. Major changes in plans were: wooded swamps were not excavated, only fallen trees and debris were removed; construction was shut down from February 1 to June 30 to avoid interference with herring spawning runs; sediment traps were constructed at critical points; 15 ft wide grass strips were established on banks in non-forested land; channels were excavated from one side only; spoil banks were placed 15 ft from the channel bank in critical areas and were seeded with stabilizing vegetation; clumps of trees were preserved at 200-300 ft intervals; and channel banks were sloped 1:1 except for some experimental areas with 2:1 and 3:1 slopes. Monitoring of fish and wildlife, water quality, and groundwater condition was started before construction and will continue until about 1986. As a result of this landmark suit, watershed planning has become more comprehensive and considerate of environmental values.

AN - 733488467; 16662180 AB - Crown galls induced by infection of tobacco plants with Agrobacterium tumefaciens strain C58-Cl(pTiB6S3) were excised and cultured in vitro. After about one year of culture on medium-lacking phytohormones, two noncloned lines spontaneously formed shoots. Leaf explants from shoots of tumor-line T5 were capable of growing on hormone-free medium, and the resulting mixture of organized and unorganized tissue synthesized octopine. Detached leaves from T5 shoots also synthesized octopine. These results establish that shoots from this octopine-type tumor contain transformed cells and are true crown-gall teratomas.

However, analysis shows that a higher % of the nonmetropolitan population participated in food stamps & SSI in 1980. Also, in the South a higher % of the nonmetropolitan population received AFDC than did the metropolitan population. Using administrative data, the location of nonmetropolitan counties that ranked in the highest & lowest quintiles according to % of the population participating was determined for each program. Although the geographic patterns varied somewhat among programs, the highest quintile counties were concentrated in the South. Lowest quintile counties were generally concentrated in the North Central plains states & the Western mountain states. Discriminant analysis was used to determine the combined discriminating power of per capita income, minority population, Hispanic population, average program payment per recipient, & population density between lowest & highest quintiles. The canonical discriminant function of each group was statistically significant, & the variables most closely related to each function were per capita income & minority population. Putting each county through the functions resulted in the predicted quintile classification, matching the actual quintile in more than 85% of the cases in all three programs.

Analysis focuses on 3 groups: (1) workers citing farm work as their principal activity during the year; (2) workers citing nonfarm work as their chief activity; & (3) workers not in the LF most of the year. Major variables examined include: ethnicity, age, education, days worked, wages earned, distance traveled, & major crop or livestock activity. The relationship between agricultural dependence & these variables is examined individually & then simultaneously through a discriminant analysis procedure. Preliminary findings suggest that the 3 groups of migrants differ significantly in terms of various demographic & employment characteristics & that the age, earnings, days worked, & type of agricultural activity are important variables distinguishing these groups.

An attempt is made to go beyond previous work by testing a model that integrates elements of contrasting social-psychological & structural explanations of community satisfaction. Subjective measures that account for individuals' perceptions of their residential living experiences, including evaluation of the former community, as well as many of the individual-level structural measures frequently used in past research are components in the model. In addition, measures are introduced to determine what effect, if any, changes resulting from or accompanying the move may have on inmigrants' community satisfaction. Examined are not only mobility inclinations but also whether dissatisfaction relates to support for community change. Emphasis is on whether the expanded antecedents & consequences model has greater predictive utility than previously tested models of community satisfaction. Analysis of the empirical results is in progress.

No distinct ownership and management patterns emerged among the communities studied. Community size had little influence on the choice. Factors which seemed to influence the methods selected included site specific technical factors; the political, social, and regulatory environment; and local custom and entrepreneurship. All rapid infiltration systems were owned and managed by the community they served. Greater variety existed among communities irrigating crops with effluent. Both community officials and farmers were aware of the economic value of effluent, both as a source of irrigation water and a source of nutrients, but the resources were not being used economically. Farmers generally paid the communities for the use of effluent, but they had not reduced commercial fertilizer application rates. City officials recognized the value of effluent, but did not charge for its full value. Community needs for wastewater treatment, together with farmers who perceived an opportunity for improving their supply of water and nutrients at a low cost, led to the initial development of several of the systems. Factors identified as important for successful systems operation included a long planning horizon and good working relationships between community officials and landowners.

AN - 15562250; 425405 AB - Fine-textured soil cores were saturated with KNO sub(3) solutions, withdrawn at periodic intervals and examined for mineral N forms. Reduction of NO super(-) sub(3)N were correlated with time using a first-order rate function. Instantaneous initial NO super(-) sub(3)N reduction rates were determined by taking derivatives of the rate function and setting t = 0. This procedure for estimating N-transformations may be useful where other techniques are either not adequate or not feasible for field use.

AN - 15560616; 410513 AB - A reverse phase-high performance liquid chromatography (rp-hplc) method was developed for the rapid isolation of nanogram amounts of crustacean erythrophore concentrating hormone (CECH) from invertebrate nerve tissue. Tissue homogenates from the shrimp, Paleomenetes pugio , were subjected to a multistep work-up to remove proteins and lipids prior to analysis by rp-hplc. Samples were eluted with a concave gradient of 0.1% trifluoroacetic acid (TFA) verses acetonitrile. Detection at 210 and 254 nm combined with the use of highly efficient and end-capped columns permitted the determination of less than 5 ng of CECH. Pure CECH was isolated from the columns by fraction collection followed by lyophilization of the volatile TFA buffer.

AN - 15553770; 423203 AB - The authors have studied tissue zinc levels and zinc balance in isocalorically pair-fed weanling rats on ZD liquid diets (0.9 mu g of zinc per milliliter of diet). Tissues were analyzed for zinc levels at weekly intervals while the animals were on the diets. The experimental animals were fed a ZDE diet, whereas sucrose was isocalorically substituted for alcohol in the pair-fed controls. Ethanol resulted in a mean negative zinc balance of 520 mu g over 28 days whereas controls showed a positive cumulative zinc balance of 300 mu g. Thus ethanol ingestion resulted in negative zinc balance and decreased zinc concentrations of most tissues as compared to pair-fed controls.

AN - 15549660; 421790 AB - Comparative studies of sheath blight caused by Rhizoctonia solani in standard height and semidwarf U.S. rice (Oryza sativa ) lines showed that semidwarf lines sustained more than double the reductions in both yield and milling quality sustained by closely related standard height lines. The disease developed more extensively in the semidwarfs because of the shorter distance between the waterline--the usual infection court--and the panicles. Sheath blight also severely reduced the amount of retillering and, consequently, the yield potential of the ratoon crop. JF - Plant Disease AU - Marchetti, MA AD - USDA, ARS, Texas A & M Univ. Agric.

AN - 15549620; 421788 AB - Sugarcane (Saccharum spp.) rust, first found at Meridian, MS, after Hurricane Frederick in 1979, was not observed in 1980 and 1981. Systematic inspections of plots of a known susceptible sugarcane clone planted as a test host, several thousand sugarcane lines, and clones of Saccharum spontaneum, Arundo donax , and Arundinaria gigantia were negative. Inoculations of sugarcane plants representing a wide range of germ plasms, with spores of a rust of bamboo (Bambusa vulgaris and Phylostachys bambusoides ) that was morphologically similar to the spores of the rust on sugarcane also were uniformly negative. These completely negative results strongly indicate that sugarcane rust may not survive in the Meridian area because of the long period (November to April) during which there is no actively growing leaf tissue above the ground.

AN - 15549473; 418780 AB - A conceptual framework is outlined for understanding the reasons why ungulates select the kinds of foods that they do. It consists of four morphological parameters: body size and type of digestive system (cecal or ruminant) determine the overall time-energy constraints within which the ungulate may forage selectively; rumino-reticular volume to body weight ratio determines the type of food the ruminant is most efficient in processing; and mouth size determines the ability of the ungulate to harvest selectively plant parts of individuals. Principal premises are the following: large ungulates and cecal digestors are more limited by time than are small ungulates and ruminant digestors; high rumino-reticular volume to body weight ratio is an adaption to exploiting thick cell-walled, high cellulose diets (i.e., graminoids); and low rumino-reticular volume to body weight ratio is an adaption to exploiting thin but lignified cell-walled diets (i.e., browse) JF - Journal of Range Management AU - Hanley, T A AD - USDA For.

AN - 15549099; 409263 AB - Seasonal food selection and digestibility by tame white-tailed deer (Odocoileus virginianus ) were studied in the white pine (Pinus strobus )-Canada hemlock (Tsuga canadensis ) and lowland conifer types, areas representative of important deer habitat in the northeastern United States. Deer selected highly digestible late spring, summer, and autumn diets. Winter and early spring food were less digestible. Forbs and newly grown leaves of hardwood plants were the most commonly selected late spring and summer foods; mushrooms and hardwood leaves were selected during autumn. Winter foods consisted largely of green and dry leaves of conifers and hardwoods gleaned from the snow surface. Early growth of grasses and sedges and dried red maple (Acer rubrum ) leaves were selected as soon as the snow left the ground in early spring. Lignaceous woody twigs, ferns, and trailing-arbutus (Epigaea repens ) also were consumed during this period, reducing the overall digestibility of the diet.

AN - 15546812; 399085 AB - A total of 33 triply cloned Spiroplasma strains were studied by the conventional growth inhibition test on M1A or M1D agar plates. Sera were prepared to 17 of the isolates, representing five major groups and the four subgroups (subgroups I-1, I-2, I-3 and I-4) of the Spiroplasma citri complex. Zone sizes varied with the titer and the growth rate of the spiroplasma cultures used as antigens. Test results were standardized by recording zone widths that developed on plates inoculated with cultures containing about 10 super(5) colony-forming units per ml. Zone widths in homologous tests ranged from 5 to 19 mm, but were usually at least 10 mm for all but the fastest growing spiroplasmas. Growth inhibition serology apparently functions in the spiroplasmataceae as a test applicable for differentiation at the species level, as it does in the Mycoplasmataceae. JF - INT. J. SYS.

AN - 15539662; 418651 AB - Prolonged drought between 1979 and 1981 killed or severely reduced stands of a number of grass species presumably adapted and frequently recommended for seeding rangelands in the Northern Great Plains. The drought damage took place on recently plnated as well as established 2 years or older seedings. Cultivars of the intermediate-pubescent wheatgrass complex were killed or most severely damaged. Damage was also severe on seed stands of the native green needlegrass, western and thickspike wheatgrasses and big bluegrass. Crested wheatgrass was only moderately drought tolerant, but two cultivars of Russian wild ryegrass established well even with adverse moisture conditions in the seeding year. JF - CAN. J. PLANT SCI.

AN - 15537378; 369843 AB - Thirty-four isolates of soilborne fungi comprised of 12 genera and 15 species were tested under greenhouse conditions against Verticillium dahliae , causal agent of Verticillium wilt of eggplant (Solanum melongena ). Six isolates of the soilborne fungi that reduced disease in greenhouse experiments were tested in two fields under different production systems. One isolate of Talaromyces flavus reduced disease by 76 and 67% in fields 1 and 2, respectively. Yield was also increased by 18 and 54% (by weight) and 22 and 71% (by number of fruit) in fields 1 and 2, respectively. This is the first report of T. flavus being used to control a plant disease caused by Verticillium sp.

AN - 15537095; 370253 AB - The wheat midge, Sitodiplosis mosellana (Gehin), was found in wheat heads and widely distributed in Michigan in 1981. The midge larvae were found in greater numbers in heads infected with glume blotch, Septoria nodorum (Berk.) Berk. This is the first reported association of this insect with a fungus, although other cecidomyiids in closely related genera feed on fungi. The authors describe a technique to sample the number of larvae that have completed their feeding in wheat heads.

AN - 15536780; 378594 AB - Larvae of the geometrid moth, Narraga fimetaria (Grote and Robinson), feed on the foliage of common broomweed, Amphiachyris dracunculoides (DC) Nutt., which is a serious weed of southwestern rangelands. In the laboratory, females laid an average of 251 eggs each; the egg stage lasted 6 days, the larval stage 18 days, and the pupal stage 10 days, and the adult required 2 days to reach peak oviposition, for a generation time of ca. 36 days; the calculated rate of increase thus was 1.13 times per day, and the population would double each 5.6 days. Larvae ate an average total of 1,304 plus or minus 255 mm super(2) of leaf surface of broomweed during their development; full-grow larvae were 24 mm long. In field cages, ca. 50 larvae per plant produced 45% defoliation of broomweed plants.

AN - 15536450; 369871 AB - Twenty-two Cucumis melo plant introductions, 14 cantaloup cultivars, and other selected Cucurbitaceae were evaluated for resistance to downy mildew under epiphytotic conditions at Weslaco, TX, in 1978 and 1979. Only nine plant introductions, all from India, and three cultivars had less than or equal to 50% leaf loss due to the disease. The most resistant entry was an inbred derivative of PI 124111. Cucumis sativus and Citrullus lanatus were infected in both years. Luffa cylindrica was not infected in either year. Three species of Cucurbita were infected in 1979 but not in 1978. Artificial inoculations in growth chambers produced the same differential host response that was expressed under field conditions. JF - Plant Disease AU - Thomas, CE AD - c/o Res.

AN - 15536438; 362965 AB - Survival of larval trout through the swim-up stage was determined for eyed eggs of brown trout (Salmo trutta ) planted both in the streambed and in Whitlock Vibert boxes. Tests were made in first-second-, and third-order streams and intragravel environmental factors were evaluated. Direct plants produced 2 times more sac fry than box plants and 3.5 times more swim-up fry. Sediment deposition was approximately 100% greater in first- and second-order streams than in third-order streams, and sediments accumulated disproportionately in box plants. This seemed to account for survival differences between planting techniques and among stream orders.

AN - 15536252; 378062 AB - Adults and larvae of the lady beetle Neoharmonia venusta (Melsheimer) are major predators of larvae and pupae of the willow leaf beetle Plagiodera versicolora (Laicharteg) in the mid-Atlantic region of the United States. This is the first specialized coccinellid-chrysomelid predator-prey association for the New World. The prey larvae produce complex exocrine secretions that fail to repel the predator. Because this is a specialized association, the possibility of an unidentified, active chemical attraction of the predator to the prey or host plant suggests that the predator could be manipulated for use in pest management programs.

The adults fed on the upper surface of the leaves, and the females laid eggs in the petioles; in the laboratory, they also laid eggs in the stolons. The larvae tunneled in the petioles and stolons and pupated in the stolons. The authors collected the weevil Tanyspiroideus parvulus Hustache only on Salvinia auriculata Aublet in the field, but in the laboratory it also fed on S. rotundifolia Willd. The weevil Cyrtobagous singularis Hustache was found for the first time in southern South America; it fed only on S. auriculata . Both T. parvulus and C. singularis severely damaged Salvinia and T. parvulus damaged Azolla plants in the laboratory. All three weevil species, with additional testing, could be candidates for introduction for biological control of aquatic weeds.

When eggs, first- to third-stage larvae and newly formed pupae of the horn fly were exposed to varying numbers (one to five) of adult histerid beetles, control varied with each beetle species. Both Hister species were effective predators throughout the horn fly developmental period from egg to pupa; however, H. incertus was significantly less efficient during horn fly larval-to-pupal developmental periods. Saprinus pennsylvanicus and X. orbiculatus were significantly less effective against all horn fly immature stages than either of the Hister species.

AN - 15532713; 379633 AB - Two replicate 25-acre plots were established in each of three forest types in the Missouri Ozarks -- oak, oak-pine, and pine -- to determine the stands' relationships with bird populations. Forty bird species were observed on the plots during the course of a year (1976-77). The oak and oak-pine stands supported the greatest number of bird species during the winter; the oak-pine had the greatest during the summer. Each forest type provided habitat for some bird species that were not present in the other types. The bird population would not be devastated by conversion of hardwood stands to pine in the region, but would change in composition to one more typical of the earlier successional pine stage.

AN - 15532533; 378459 AB - The phenotypic variability of several estimates of fitness among seventeen nesting female O. lignaria Cresson was examined in a glasshouse provided with abundant resources. Females exhibited wide variation in: (a) number of nests and cells made in their rate construction, (b) the incidence of mortality of offspring, and (c) the percentage of male offspring produced (52-100%). In confirmation of earlier field studies: (a) more offspring of both sexes were produced during the first half of the nesting season, (b) most female offspring were produced early in the nesting season, (c) most parental investment during the last half of the light season was made in male offspring, (d) there was a decrease in offspring size with season, with females decreasing more than males, and (e) the ratio of female/male body weight was approximately equals 1.8. The authors hypothesize that as size of offspring produced declines with season, a greater proportion of males are produced because they have a much greater probability of surviving at small body sizes.

The pathogen was eradicated from 33-44% of tip cuttings (1.0-1.5 cm long) after hot-air treatment of mother plants at 37C for 87-105 days. Survival of these tip cuttings after 35-105 days ranged from 22-73%. Exposure of entire cassava plants to hot-air treatments at 37 degree C for 42-96 days caused temporary remission of symptoms in most plants. Only one of 129 surviving plants was freed of disease. Two successive hot-water treatments of diseased stem cuttings at 50 or 55 C for varying intervals were not therapeutic. JF - Plant Disease AU - Kaiser, W J AU - Louie, R AD - Reg.

AN - 15531830; 370046 AB - Large horizontal Douglas-fir timbers with interior decay fungi were used to evaluate the effectiveness of Vapam (sodium N-methyl dithiocarbamate) and chloropicrin in controlling decay fungi. Fumigants were applied in holes drilled in the timbers or flooded into checks. The efficacy of the fumigants in arresting interior infection was evaluated by comparison of the fungal population after fumigation to that prior to fumigation for a 16-month period. Both chloropicrin and Vapam controlled the growth of decay fungi in the interior of Douglas-fir timbers. Neither fumigant was as effective in controlling molds as in controlling decay fungi. JF - F.

AN - 15531705; 369833 AB - The bumper wheat crop of 1915 in the United States and Canada was followed in 1916 by a season that started out cool and moist. The crop was late in the northern Graat Plains, wheat growth was lush, and conditions in May and June were ideal for development of stem rust (Puccinia graminis Pers.), Barberry bushes, an alternate host of the fungus, were severely rusted early in the season, and by early July stem rust was present on wheat throughout the spring wheat area. Hot humid weather in May through July favored rust development, and a change to hot dry weather in August ripened the crops prematurely with disastrous effects. After many meetings and conferences of agricultural and military officials, a national program for the control of stem rust evolved. A part of the program was a plan to eradicate the principal alternate host, the common barberry (Berberis vulgaris L.). JF - Plant Disease AU - Roelfe, A P AD - Cereal Rust Lab., ARS, USDA, Univ.

Tui. and T. foetida (Wallr.) Liro, have caused losses to wheat production throughout recorded history wherever wheat is grown. Although common bunt is no longer a major production problem, another bunt disease, called dwarf bunt, has tenaciously resisted efforts toward control. This disease, caused by T. controversa Kuehn, while more limited in distribution and sporadic in occurrence, continues to cause occasionally severe losses to winter wheat in the northwestern United States and certain other countries.

AN - 15523480; 360633 AB - On Barro Colorado Island, Panama, conflict occasionally occurs between Turkey Vultures (Cathartes aura ) and Howler Monkeys (Alouatta palliata ) apparently for choice early-morning sunning sites. Vultures have previously been documented to require early-morning solar radiation to facilitate feather-drying and/or elevation of body temperatures. No such mechanisms have been documented as necessary for Howler Monkeys. A hypothesis is presented suggesting that behavioral thermoregulation in howlers is a required part of the general strategy of utilizing an energy-poor diet. Heat obtained from solar radiation may reduce demands on metabolic energy for maintaining proper body temperatures and increase the efficiency of digestive fermentation.

AN - 15522265; 352022 AB - The authors investigated the effects of soil microfauna feeding on a soil bacterium (Pseudomonas cepacia ) and the resultant influence on net N mineralization. As the bacterial biomass increased, it assimilated N from the soil. Later, only if this bacterial biomass decreased was N remineralized. Grazing by amoebae (Acanthamoeba polyphaga ) always reduced bacterial biomass, increased respiration, and increased nitrogen mineralization. Grazing by nematodes (Mesodiplogaster lheritieri ) always reduced bacterial numbers and increased respiration, but only increased N mineralization when nematode populations themselves declined from peak values. Experiments showed that microfauna can play an important role in N mineralization in soil and that the mechanism for this role is more likely to be through direct excretion by the grazers than through indirect physiological effects on the bacteria.

Greatest contamination of the product occurred at the location where ova were drawn from the carcasses. Water fluming and chilling procedures caused some reduction in contamination levels. Total aerobic plate counts, coagulase-positive staphylococci, presumptive Clostridum perfringens and Enterobacteriaceae counts of chilled ova were low, and no salmonellae were detected on these samples. Since intact ova are shipped refrigerated to egg processing plants for further processing and pasteurization before use in food products, there should be little concern about microbial food safety of ova.

AN - 15522223; 351975 AB - An isolate of maize rayado fino virus from infected corn in the United States (MRFV-US) was purified. Yields were usually 30-80 mu g of virus per gram of tissue. A noninfectious top component (47S) containing no nucleic acid, and an infectious bottom component (124S) containing a single RNA species (2.4 x 10 super(6) daltons) were separated. The RNA was single-stranded, comprised 26% of the bottom component by weight, and contained 31.4% Cp, 23.1% Gp, 16.8% Ap and 28.7% Up. The top and bottom components banded isopycnically in CsCl at densities of 1.265 and 1.425 g/ml, respectively. Two proteins (MWs 25,600 and 22,350) were found in each component in the same ratio, about three molecules of the lighter protein per molecule of the heavier. Partially purified MRFV-US had a thermal inactivation point between 90 and 100 C, dilution end point between 10 super(-4) and 10 super(-5), and longevity in vitro between 9 and 11 wk. Infectivity of partially purified preparations was preserved by lyophilization. The cryptogram for the bottom component is R/1:2.4/26:S/S:S/Au. Enzyme-linked immunosorbent assay was used to detect MRFV in individual Dalbulus maidis leafhopper vectors and to show that the amount of virus in leafhoppers declined between 0 and 7 days, increased between 7 and 14 days, and remained high through 21 days after acquisition, indicating that MRFV multiplied in this vector.

AN - 15519578; 352506 AB - The effect of 5 soil fumigants (Dowfume MC-2, fumazone 86, telone C, vortex, and temik 10G) on the survival of apple treees in a peach tree short life site (PTSL) was studied. Of the 22 trees which succumbed during this experiment, 12 were infected with southern blight (Sclerotium rolfsii ), 5 with bot canker (Botryosphaeria dothidia ), 1 with collar rot (Phytophthora cactorum ), and 1 with clitocybe root rot (Clitocybe tabescens ) at the time of death. Substantial tree losses can be expected in areas where S. rolfsii is commonly found. Factors previously associated with PTSL did not appear to be direct causative factors in the loss of apple trees. However, these factors could not be excluded as predisposing factors on the basis of this study. Preplant fumigation may increase survival on these old orchard sites. JF - RES. BULL. UNIV. GA. COLL.

Three methods were compared for obtaining an even dispersion of inoculated Salmonella in mash and pelleted feed. A twin-shell blender, which tumbled the feed in a "V"-shaped container, was most efficient with recovery of inoculated Salmonella in 49 of 50 samples. Shaking in a polyethylene bag was also effective; inoculated Salmonella were recovered from 45 of 50 samples. A Waring blender was least effective; Salmonella were recovered in only 16 of 50 samples.

Generally, neither freezing nor temperature-abuse had a significant effect. Vacuum-packaged beef tongues and livers, generally, had lower bacterial counts than did either naked or polyvinyl chloride film-wrapped products. Generally, it was observed that abusive storage temperatures, in conjunction with the naked and film-wrapped packaging systems, appear to present potential microbial spoilage problems when compared with vacuum packaging.

AN - 15518576; 353324 AB - Inbred lines of crimson clover (Trifolium incarnatum L.) were assayed for N sub(2) fixation using the acetylene reduction assay. The seedlings were inoculated with a single pure strain (162K 13) of Rhizobium trifolii) and cultured in a nil-nitrogen nutrient solution contained in individual plastic growth pouches. The acetylene reduction assay was carried out on live plants using the plastic pouches to contain the gas mixture. In the first experiment, significant differences were noted among 14 crimson clover lines for acetylene reduction. Top dry matter, leaf number, and visual scores of nodulation, root growth and top growth were significantly correlated with the acetylene reduction assay. A relatively large coefficient of variation (27.1%) was noted for this experiment. In the second experiment refinement of culture and assay techniques resulted in a lower coefficient of variation (15.2%) and significant differences among six crimson clover lines for acetylene reduction were found.

The most rapid kill of the greatest number of plants was obtained using a 25% Hoagland's nutrient solution, shading the plants for 3 days after adding the inoculum, and using infected fresh plants as inoculum. Shading the plants was essential for high mortality of susceptible genotypes. Susceptible plants grown in distilled water were killed as rapidly as those grown in nutrient solution if infected fresh plants were used as inoculum and plants were shaded.

AN - 15518147; 352926 AB - Competition between developing ergots (sclerotia) of Claviceps purpurea and developing seed for super(14)C-labeled photosynthates translocated from leaves of intact infected rye plants was compared with translocation of super(14)C-labeled photosynthates into seeds of healthy plants. Competition for photosynthates followed the early establishment of the stromatic foot, the absorbing organ of the parasite, which remained active during the entire 6 wk even though the sclerotial tissue located above had matured in 3-4 wk and no longer incorporated photosynthates. The flow of nutrients into the sclerotium decreased as it developed acropetally. Seeds and sclerotia of diseased rye plants incorporated more super(14)CO sub(2) than did seed of healthy plants, which reflected a larger and more efficient energy sink. Seeds from healthy plants completed development at the end of the 6-wk period as indicated by dry weights and decline in the uptake photosynthates. However, development of competing seeds on infected plants was retarded until the fourth week when high levels of translocation and increases in dry weight resumed after a concurrent decline in photosynthate translocated to competing ergots.

AN - 15517650; 350799 AB - A Salmonella survey was conducted to determine its incidence in fresh pork sausage. Retail size samples representing different days of production were collected from 40 federally inspected plants and analyzed for the presence of salmonellae. The results obtained during the 1979 survey were compared to results obtained in a similar 1969 survey. Salmonellae were isolated from 162 of the 566 (28.6%) samples analyzed in 1969. For the samples analyzed in 1979, 74 of 603 samples (12.4%) were positive for salmonellae. The reduction of 16.2% over 1969 indicates a reduction in the incidence of Salmonella in this product for the firms tested.

AN - 15513792; 347191 AB - Cereal leaf beetles (CLB), Oulema melanopus (L.), oviposited more eggs on "Downy" winter wheat, Triticum aestivum L., than expected based on its previous classification as very resistant to the CLB. Within a field of Downy, beetles oviposited on those leaves with fewer and shorter trichomes. The trichome profile (length and density) of all leaves were determined for Downy grown in southwestern Michigan. Trichome profiles differed significantly between years for the same leaf number and between different leaves the same year. The flag leaf was not as resistant as the three leaves below it. The overall trichome profile was best estimated by samples from the mid-region of the leaf. Trichome density of the seedling first leaf was positively correlated with leaf length and negatively correlated with soil moisture in laboratory studies. Trichome profiles of the first seedling leaf were positively correlated with temperature. Downy grown in the field in 1979 was rated between susceptible and moderately resistant (depending upon which leaf was rated). JF - Crop Science AU - Wellso, S G AU - Hoxie, R P AD - USDA-ARS, Dep.

Female beetles made the initial entry into the trees and only one female and male occupied each egg gallery. The period of attack per tree ranged from 5-17 days and the density of attack ragned from 2-41 galleries/1,000 cm super(2) of surface area. Over 50% of the parent adults reemerged after egg gallery construction and ovisposition. The egg stage was from 7-110 days, the larval stage from 25-332 days, the pupal stage from 17-181 days, and the adult stage from 7-215 days. The beetles overwintered in the adult and larval stages. Spring emergence began about May 11, 1979 and about May 6, 1980. Two generations occurred each year. JF - J. GA. ENTOMOL. SOC. AU - Rexrode, C O AD - USDA, For. Serv., Northeastern For. Exp.

AN - 15513073; 333921 AB - Four inoculation techniques for evaluating reaction of maize to infection of kernels by A. flavus were tested in the field on 10 commercial maize hybrids representing a range of kernel hardness. Inoculations were made 20 days after the midsilk stage, and at maturity kernels not wounded during inoculation were surface sterilized and plated to determine the percentage infection. Inoculation by injecting an A. flavus conidial suspension into the silk channel or by atomizing a conidial suspension onto exposed kernels resulted in infection levels too low ( less than or equal to 7%) to adequately differentiate among genotypes. Kernel injection and pinbar inoculation techniques, in which kernels near wound-inoculated kernels were assayed, demonstrated significant differences among some hybrids. The pinbar technique was considered best because it resulted in higher levels (9-48%) of kernel infection, was relatively easy to use, and provided a large number of kernels for assay. Kernel hardness was not correlated with reaction to kernel infection. JF - Phytopathology AU - King, S B AU - Scott, GE AD - USDA, ARS, and Dep.

AN - 15510134; 336408 AB - Laboratory studies and field observations involving polychlorinated biphenyls (PCB's) and related compounds were used in making an assessment of residues in animal products from the applications of sewage sludge to agricultural land. Animals can become exposed to PCB's applied to land by three routs: direct ingestion of sewage sludge that adheres to plants during sludge application, ingestion of plants indirectly contaminated by uptake or volatilization from the soil, and ingestion of contaminated soil when grazing. The last route has the greatest realistic potential for producing residues in animal products from a given rate of long-term application of PCB-contaminated sludge to land. Feeding experiments with PCB's indicate that the steady-state milk-fat concentrations are about five times the diet concentrations (dry basis) in dairy cattle and that the steady-state bodyfat concentration will be similar in non-lactating animals.

Eating the test meals led to a slight increase in nitrosamine levels in the blood and stomach contents in a few subjects. The data obtained from this study suggest that gastric formation of nitrosamine does not appear to be an important health factor in normal people, since the levels of nitrosamines found in physiological fluids are not markedly increased after eating.

AN - 15506653; 316842 AB - Pole sized stands of Populus tremuloides Michx., Picea glauca (Moench.) Voss, Pinus resinosa Ait., and Pinus banksiana Lamb., were sampled on obth a very fine sandy loam and a loamy sand. Relative species ranking in above-ground tree biomass (Pinus resinosa > Populus > Picea > Pinus resinosa > Pinus banksiana ) were similar on both soils. Particularly large proportions of biomass and nutrients were found in aspen bark and spruce foliage and branches on both soils. Harvesting entire above-ground trees would remove up to three times more nutrients than would harvesting only the bole. Herbs and shrubs had less than 3% of the total vegetation organic matter but contributed as much as one-half of the total annual litterfall nutrients. Litterfall weights and nutrient concentrations, and especially forest floor nutrients, were all less on the loamy sand. Ca in the above-ground Populus amounted to 18% (very fine sandy loam) to 25% (loamy sand) of the exchangeable Ca in the total complex. Intensive utilization of this species in particular could stress the Ca economy of these sites. JF - PLANT AND SOIL. AU - Perala, DA AU - Alban, D H AD - North Central Forest Exp. Stn., USDA, For.

AN - 15504926; 342296 AB - Responsible resource use depends largely on accurate inventories, which implies the creation of a land classification system because an inventory without classification is mainly an unorganized list. In this paper the authors develop a simple classification system based on causes of differences between classes and integrate the riverine with the terrestrial to form the basic ecological system. Within this concept, diverse users of the system such as fishery managers, timber harvesters, and livestock grazers have a common classification base from which to operate. Thus, this land-water classification system will help managers meet the increasing demands placed on all resources while giving the fishery the optimum input into the decision-making process.

Duration of heating and temperature requirements varied according to the physical and chemical properties of the fungicide. Treatments were applied at night to allow the greenhouse to be tightly sealed in order to maintain an effective dosage. Fenarimol and fenapanil effectively controlled rose powdery mildew and caused no phytotoxic effects. Volatilization of fungicides offers ease of application, uniform distribution, and reduced hazard to greenhouse personnel.

AN - 15504025; 342277 AB - Data collected on 129 recaptured Gila trout (Salmo gilae ) in three streams on the Gila National Forest, New Mexico, indicated that this endangered trout tended to stay near "home" (mean movement < 0.1 km) and grew less, both in streams containing larger fish populations and streams containing log improvement structures, than in other streams. Those fish that moved went greater distances downstream. Few fish (< 2%) moved upstream over habitat-improvement structures, and such movement was limited by structures greater than or equal to 0.5 m high. In one intermittent stream, these fish oriented to permanent-water reaches.

AN - 15503634; 333400 AB - The development of C. insidiosum was adversely affected by the presence of F. oxysprorum f.sp. medicaginis in the field, the glasshouse, and in vitro. In the field, bacterial wilt symptoms were less severe in roots of alfalfa plants inoculated with a mixture of C. insidiosum and F. oxysporum than in plants inoculated with C. insidiosum alone. This effect was greater in cultivars susceptible to bacterial wilt that in resistant cultivars. In the glasshouse, C. insidiosum developed more slowly in alfalfa roots inoculated with a mixture of both pathogens than in roots inoculated with C. insidiosum alone. The sterile filfrates of four isolates of F. oxysporum f.sp. medicaginis grown in a nutrient broth in still and in shake culture were added to agar medium seeded with C. insidiosum . Filtrates from the still cultures (mostly mycelium) inhibited C. insidiosum and reduces bacterial wilt severity in alfalfa plants.

AN - 15503291; 335217 AB - Virulence of H. annosum (= Eomes annosus ) isolates from different geographic locations throughout California was evaluated by inoculation of ponderosa pine trees in the field and seedlings in the greenhouse. Tests were designed to compare isolates obtained from areas of chronic photochemical air pollution exposure with some from areas relatively free from pollution. Isolates displayed a wide range of virulence based on number of plants infected and rate of colonization. Percentage of infection varied from 4 to 74 in the greenhouse and from 0 to 50 in field tests. Colonization rates showed a 17-fold difference among isolates. However, relationships between geographic origin and level of virulence were not evident. Isolates from areas of relatively high, chronic air pollution exposure were generally as virulent as those from environments with little or no pollution.

AN - 15503028; 333362 AB - Conidial discharge by C. caryigenum from heavily diseased pecan leaf and nut shuck (involucre) tissue was studied under controlled exposure to relative humidity (RH), temperature, vegetative wetness (VW), and infrared radiation (IR). Spore release was minimal as RH decreased from near saturation to 40%, but further decrease stimulated considerable spore discharge which was enhanced by exposure to IR (> 40 mu E multiplied by m super(-2) multiplied by sec super(-1)). Sustained periods of constant RH < 40% also favored spore release but were less favorable than RH that fluctuated above and below 40%. Spore release was stimulated by short (circa 1 min) IR exposures and brief (2-min) RH changes. Spore release was recorded only as the specimen dried off or when leaf wetness was maintained < 15%. Vibration triggered spore release at low RH, especially when specimens were exposed to IR, but vibrational effects were considerably less effective than those reported previously for other hyphomycetes.

AN - 15502842; 306439 AB - Seventeen chemicals, mostly organic and inorganic acids, were tested in combination with gypsy moth nucleopolyhedrosis virus (NPV) for enhanced pathogenicity in L. dispar (L.) larvae. Two acids (sorbic and boric) appeared to enhance viral activity, as expressed by increased mortality in treated larvae. The effects of boric acid were investigated more thoroughly, and in each test boric acid significantly enhanced viral activity (LC sub(50) of NPV-H sub(2)) standard = 5.0 x 10 super(3) polyhedral inclusion bodies (PIB)/ml LC sub(50) of NPV-BA = 0.8 x 10 super(3) PIB/ml). The addition of boric acid to NPV enhanced activity when tested on both semisynthetic diet and red oak seedling. Concentrations of 0.1 and 0.25% BA had no effect upon NPV-induced mortality, whereas 0.5% BA enhanced NPV activity 2-fold and 1.0% BA enhanced activity ca. 11-fold. Moreover, the time from inoculation to initial mortality as well as the LT sub(50) were reduced by the addition of boric acid. The potassium and ammonium salts had no effects upon viral activity, but the sodium salt was as effective as the acid.

This is the first and only confirmed occurrence on this host in Alaska since a single, uncertain collection in 1913. A. tsugense infects this host less commonly in Alaska than in the western contiguous United States, where T. mertensiana is a principal host for A. tsugense . The relative infrequency of infection, unusually large swellings at the point of infection, and sparse shoot development suggest some degree of host-parasite incompatibility.

AN - 15502325; 312214 AB - An acid settling pond located in Barton County, Missouri, was temporarily drained September 15 and September 16, 1980, for reconnaissance investigations. The pH of the acid pond, on September 15, 1980, was pH 2.6; the pH of the pumped pond water in a receiving pond on September 16, 1980, was pH 5.6. It is believed that acid water removed from the source of acid production can, by treatment with calcium carbonate (CaCO sub(3)), be raised to a pH above 6.5. Considerable savings may occur by treatment of acid waters removed from the source of acid production with only calcium carbonate (CaCO sub(3)) versus inplace mixture treatments of calcium carbonate (CaCO sub(3)) and hydrated lime (Ca(OH sub(2))).

AN - 15502289; 333394 AB - Nine corn (Zea mays ) inbred lines were examined after inoculation with isolates of C. carbonum race 3 (= Helminthosporium carbonum ) differing in levels of virulence. Reaction was measured by determining the effects of the lines on three components of parasitic fitness: disease efficiency, lesion length, and sporulation capacity. Differences among host genotypes were significant when tested against the six isolates. Similarly, isolates differed significantly in their degree of virulence on the host lines. Host X isolate interactions for the three fitness traits were significant suggesting that isolates responded differently to different hosts. Regression analysis was used to determine the stability of resistance. An inbred line was defined as having stable resistance when it had a low mean disease rating, a regression coefficient near zero, and small deviation from regression. The large variation detected in this study suggested that stable resistance in corn lines to C. carbonum race 3 would not easily be found.

Evidently, the structure of the corn plant protects N. pyrausta spores from the detrimental effects of ultraviolet radiation. Aqueous suspensions of spores of N. pyrausta and Vairimorpha necatrix (Kramer) were applied separately to corn foliage in both the whorl and pollen-shedding stages of plant development. European corn borer larvae exposed to N. pyrausta had an equal or greater prevalence of microsporidiosis than those exposed to V. necatrix during both stages of plant development. During the whorl stage of plant development, insects exposed to V. necatrix had a greater intensity of microsporidiosis, measured as spores per mg of infected tissue. Both microsporidia caused an infection in corn borer larvae 12 days after application. JF - Journal of Economic Entomology AU - Lewis, L C AD - Corn Insects Res.

AN - 15501991; 334141 AB - Soybean plants (Glycine max "Kent') inoculated with the vesicular-arbuscular mycorrhizal (VAM) fungus Glomus fasciculatus were grown in 1.5-L pots in a perlite/sand rooting medium containing 200 mg of hydroxyapatite (Ca sub(10)(PO sub(4)) sub(6)(OH) sub(2)) as the source of P. Plants were harvested at 2- or 3-wk intervals for 18 wk. Fungal biomass as percent total dry weight (of the host and symbiont) was calculated from measurements of fungal chitin and had a maximum value of 7.3% at 6 wk after planting. Total and percent P content of VAM-infected and uninfected control plants were determined, and the decrease of available (NaHCO sub(3)-extractable) P in the rooting medium was monitored. The data suggest that early growth inhibition was a result of carbohydrate demand on the host by the endophyte, at a time when the shoot-to-root ratio and photosynthetic source capacity of the host were low. Available P in the rooting medium of VAM plants decreased to 10 mu g P/g rooting medium during the 3 wk preceding the reversal in growth inhibition, indicating that mycotrophic growth of the host induced by increased P uptake by the endophyte commenced at this P concentration.

The WP did not completely eliminate moth emergence at rates as high as 625 mg/kg when applied as either a bulk or surface layer treatment. Efficacy of the WP was not improved by more uniform application. The dust nearly eliminated moth emergence when used as a surface layer or bulk treatment at 500 mg/kg.

The mycoparasite was applied to the field plots in May 1978 at 0, 1, 10, 100, and 1,000 conidia per gram (c/g) of soil. During the summer of 1978, S. slerotivorum caused a 75-95% reduction in the numbers of sclerotia of S. minor in plots that had received 100 and 1,000 c/g of soil, respectively, compared to only 25% in the control. Disease control in these plots for four consecutive lettuce crops during the spring and fall of 1979 and 1980 varied from 40 to 83% compared with the disease incidence in the untreated plots. The mycoparasite became established in the field plots and caused infection and subsequent destruction of sclerotia produced on the diseased lettuce.

MGmNPV virus produced in vivo and in vitro and applied at a dose of 1 x 10 super(9) polyhedral inclusion bodies per section (5 by 10 cm) of drawn honey comb proved efficacious under laboratory conditions. Similar results were obtained under field condition where economically important damage was prevented with similar dosages. A cost of 22 cents per 10-frame hive was calculated for in vitro-produced virus used in control studies.

AN - 15495525; 315855 AB - Effects of ozone (O sub(3)) on certain cultural characteristics of Fomes annosus) were investigated in exposure chamber studies. Growth rates of F. annosus decreased and conidial germ tubes were shorter and had fewer branches as O sub(3) dosages increased. F. annosus) conidial production was very sensitive to O sub(3); very few conidia were produced when cultures were exposed to relatively low doages (2,400 mu g/m super(3)-hr). Conidial germination was decreased at the higher O sub(3) dosages, but spore germination was apparently stimulated at low dosages (184 mu g/m super(3)-hr). Colonization of wood disks exposed to O sub(3) dosages of 16,870 mu g/m super(3)-hr and greater was significantly less then that of nonexposed disks. However, O sub(3) dosages that can be expected under field conditions appear to have little potential effect upon those aspects of pathogen biology that would substantially affect epidemiology of annosus root rot.

Gamma irradiation at the dose of 50 Mrad or greater extensively degraded and solubilized sugarcane bagasse in water, but direct production of fermentable sugars from biomass by gamma irrradiation was difficult because of decomposition of the sugars.

AN - 15493039; 299954 AB - Nuclear polyhedrosis viruses isolated from the alfalfa looper, Autographa californica (Speyer) (AcMNPV), and a mint looper, Rachiplusia ou (Guenee) (RoMNPV), were assayed against the European corn borer, Ostrinia nubilalis Huebner), and applied to field corn for suppression of this insect. Fourteen days post-treatment, LC sub(50) values were 46.50 and 0.95 x 10 super(5) PIB/ml diet for AcMNPV and RoMNPV, respectively. Both viruses caused significant reductions in number of larvae per plant and in plant damage when the material was applied with a backpack sprayer. Data indicate that RoMNPV kills in less time than AcMNPV. When the viruses were applied with a commercial highboy applicator, the centimeters of damage to cornstalks was reduced by 65% with RoMNPV during the 1st generation and by 32.9% in the 2nd generation.

AN - 15491951; 300422 AB - Electron micrographs of leaf intercellular spaces of the soybean (Glycinemax ) differential cultivars Flambeau and Harosoy spray inoculated with P. syringae pv.glycinea showed bacterial cells of both homolgous and heterologous strains occasionally enveloped by electron-dense material at 4 and 24 hr after inoculation. However, there was no evidence that this was an active or specific host response. Structures similar to those enveloping bacteria were found cross-bridging adjacent leaf mesophyll cells at cell junctions in water-infiltrated and, to a lesser extent, uninfiltrated leaf tissue. Bacterial envelopment was not seen in several heterologous P. syringae pv. Glycinea -soybean combinations, even though a typical hypersensitive response was induced, indicating that bacterial attachment per se is not a prerequisite for induction of the hypersensitive response in soybean. From experiments with rifampicin, induction time for the hypersensitive response was determined to be between 2 and 4 hr. JF - Phytopathology AU - Fett, W F AU - Jones, S B AD - East. Reg. Res.

Spreng. All but three of the fungi formed arbutoid mycorrhizas. Sheathing fungal mantles, Harting net penetration and intracellular colonization were well developed on most mycorrhizas. These results confirm that ectomycorrhizal fungi form arbutoid mycorrhizas and that these particular hosts are broadly receptive towards fungal associates. The significance of these results with respect to ecological and practical implications and better understanding of ectomycorrhizal specificity is emphasized. Arbutoid mycorrhizas are most closely related to ectomycorrhizas than to ericoid mycorrhizas. JF - New Phytologist AU - Molina, R AU - Trappe, J M AD - Pacific Northwest For. and Range Exp.

AN - 15491577; 301248 AB - A computer-based system (IRIS) was developed to compare infection types produced by the interaction of cultures of P. graminis on hosts with designated Sr resistance genes, and to postulate the rust resistance genotype of the host by the use of disease infection types. The user is guided by IRIS through Time Sharing Option command procedures to the appropriate program in a series of connected interactive Statistical Analysis System programs. IRIS is currently operational on the IBM 370/168 at the U.S. Department of Agriculture, Washington Computer Center in the South Building and can be accessed by remote terminal. IRIS sorts races and permits the user to compare infection types produced by all previously evaluated cultures on 45 "single" genes for resistance with newly evaluated cultures. Infection types of newly characterized cultures can be selectively added to the system, as well as infection types produced on newly characterized host resistance, Sr genes. The infection types produced by the 51 cultures most frequently used and the 46 characterized Sr genes were placed in a base file. The infection types in this file were used to postulate host resistance genotypes of host lines infected with some or all of the cultures.

AN - 15490989; 317552 AB - Shiitake is the major edible mushroom in Asia. In 1978, the Japanese shiitake industry employed 188,000 people and generated $1.1 billion in retail sales; dried shiitake was Japan's major agricultural export. Successful commercial cultivation began in the 1940s in Japan with the development of new inoculation techniques. Small diameter hardwood logs, especially oaks, are the preferred material on which to cultivate this nonpathogenic fungus. Optimum yields may be as high as 2.5 to 10.5 percent on a dry weight basis (9% to 35% fresh weight basis). Markets exist within the United States for the sale of shiitake. Although suitable hardwood species are available in many areas of the United States and the climate often acceptable, current U.S. shiitake production is limited, primarily because of the lack of accessible information on shiitake and its cultivation. This article outlines the history of shiitake cultivation in Japan, describes the food value of shiitake, and also provides information on how to cultivate the mushroom on logs in the United States.

AN - 15489426; 287784 AB - Systematic studies of factors that inactivate soya bean trypsin inhibitors showed that thiols facilitate heat inactivation, as illustrated by the following examples. Heating soya flour in an aqueous medium in a water-bath from 25 to 93 degree C for 1 h showed that heat alone does not begin to inactivate the inhibitor until about 55 degree C (around 10% inactivation). The corresponding value at 85 degree C is 60%. In contrast, inactivation in the presence of N-acetylcysteine proceeds more rapidly, as shown by 70% inactivation at 55 degree C and 94% at 85 degree C. These results, and additional data, illustrate the complementary co-operative effect of heat and thiols in inactivating soya bean trypsin inhibitors in commercial soya flour. The thiol treatment also strikingly enhances the in-vitro digestibility of soya proteins by trypsin. The results are discussed with reference to the role of disulphide bonds in the mechanism of enzyme inhibition.

AN - 15489365; 301213 AB - Sapwood and heartwood of Douglas-fir (Pseudotsuga menziesii ) were incubated from 2 to 16 weeks in agar-block chambers with a white-rot fungus (Coriolus versicolor ), a brown-rot fungus (Poria placenta ), or no fungus. Measurements of electrical resistance, moisture content (MC), and weight loss due to decay were made at 2,4,8, and 16 weeks. These measurements indicated that the electrical resistance of all inoculated, decaying wood blocks was consistently and substantially lower than noninoculated, nondecaying control blocks. These differences occurred at all time intervals and long before there were any visible indications of decay or any measurable weight loss. The differences in electrical resistance were attributed to differences in the concentration of positively charged ions in solution.

AN - 15483022; 287166 AB - This paper describes responses of peanut storage globulin (arachin) to rancid oil and hydrogen peroxide as measured by electrophoretic mobility, antigenicity and circular dichroism of the globulin. Rancid oil and 3% hydrogen peroxide had little effect on these properties but 30% hydrogen peroxide increased the mobility, abolished the antigenicity and reduced the ordered structural modes of the protein. The results indicated that changes in protein conformation do not occur after contact with organoleptically rancid oil or dilute peroxides but do occur with concentrated peroxides.

AN - 15469631; 264797 AB - A two-parameter farm pond storage index, FPSI, was used to adjust computed surface runoff using the partial area runoff contribution resulting from runoff captured by farm ponds. The validity of the index method was tested by fitting a continuous accounting version of the Soil Conservation Service curve number procedure to surface runoff data from each of three watersheds, first with and then without the FPSI routine. Evapotranspiration computed with the Jensen-Haise method and rainfall were input to the model. A linear relationship was assumed between the storage index and the portion of the controlled drainage area that was contributing to runoff. Adjusting the computed runoff with the FPSI reduced the coefficient of variation of monthly measured versus computed surface runoff for each of the three watersheds. The correlation coefficients for the same comparisons were increased. The annual predicted surface runoff was improved for 12 of the 17 station years of data tested.

AN - 15468308; 263910 AB - The authors examined predictions of the theory of energy maximization for a field population of several species of bees foraging for nectar and pollen on a planting of six male-sterile and one male-fertile sunflower, Helianthus annus , cultivar. Honey bee (Apis mellifera ) and bumble bee (Bombus ) workers gathered only nectar from sunflowers and mostly visited the two male-sterile cultivars that supplied the greatest caloric rewards; pollen was collected from other sources. Individuals of nonsocial species such as Melissodes agilis preferred the male-fertile cultivar (the only one supplying pollen), although it was lowest in caloric reward, because of their requirement for pollen for brood provisioning. Specialized workers of social species typically collect either nectar or pollen and presumably maximize caloric or nutrient acquisition. In contrast, individuals of nonsocial bee species forage for a mixed currency (energy and nutrients) and should not be expected to behave as predicted by the theory of energy maximization.

Part 1. Composting of Industrial Wastes Greatly Reduces the Potential for Environmental Damage Resulting From Direct Land Application. AN - 15465580; 275226 AB - The primary objective of land treatment of industrial wastes is to utilize the chemical and microbiological capabilities of a soil to enhance the chemical and/or biological detoxification, degradation, and inactivation of a given waste, thereby rendering it less hazardous and less toxic to human and animal health. Unfortunately, industrial wastes in many cases have been disposed of on land with little consideration as to the principles and parameters involved. This paper discusses a number of important principles that should be considered for safe and effective land treatment of industrial and hazardous wastes. It also suggests some strategies that may be useful in developing acceptable management practices for land treatment systems.

AN - 15463213; 268074 AB - Vitellin was isolated from oocytes of L. maderae and fractionated into 14S (subunit structure ABC sub(2)D sub(2)) and 28S (subunit structure AB sub(3)C sub(2)) complexes. Chromatography on DEAE-cellulose in 8 M urea partially separated the subunits from each other and provided evidence for two kinds of B subunit in 28S Vt. Amino acid analysis of each subunit purified by SDS gel electrophoresis showed significant differences in the contents of a few amino acids. The leucine, lysine and valine content of A sub(14) and A sub(28) differed from the other subunits and the alanine content of C sub(14) and C sub(28) was less than half of the others. B sub(14), D sub(14) and B sub(28) had similar amino acid compositions. Using antisera prepared against each subunit, a strong immunologic identity among the B sub(14), D sub(14) and B sub(28) subunits was found, with weak cross-reaction to A sub(14) or A sub(28). A sub(14) appeared identical to A sub(28) and the C sub(14) and C sub(28) were identical to each other, but the C subunits did not cross react with any other subunit. JF - INSECT BIOCHEM.

C. Johnston, velvet mesquite, P. velutina Wooten, and white mesquite, P. alba Grisebach, but not on screwbean mesquite, P. pubescens Bentham. Adults emerged from overwintering pupae in April and May. Populations of larvae in the field were always low, and larvae caused little damage to mesquite trees. Parasitism of larvae in the field reached 20% during the last two instars, mostly from tachinid flies. Each larva ate ca. 26 cm super(2) of leaf surface (about one mesquite leaf) during its life. In the laboratory, adults laid an average of 152 eggs each. Four days were required for the egg stage, 27 days for the larva, 11 days for the pupa, and 3 days for adults to reach peak oviposition, for a generation time of ca. 45 days.

AN - 15455799; 258216 AB - In studies conducted in eastern Washington, seven species of weeds provided the food source of pre-overwintering lygus bugs, Lygus spp. The two major weed species were volunteer alfalfa, Medicago sativa , and lambsquarters, Chenopodium spp. Winter survival of lygus bugs feeding on several species of weeds in the fall did not differ significantly. Winter survival of lygus bugs was low when the material in which the lygus bugs were overwintering was maintained under 10% of dry weight. Deciduous orchard duff was found to be the major overwintering site of adult lygus bugs, but considerable numbers overwintered in large mullein, Verbascum thapsis L., plants.

AN - 15454921; 261205 AB - Exposing casein to alkali (0.1N NaOH at 65 degree C) partly racemized the amino acid residues. A plot of D/L ratios for seven amino acids versus time of treatment shows fast initial racemization rates that decrease after about 1 hr. A linear free energy relationship exists between racemization rates and inductive effects of amino acid side chains or R-substituents ( sigma *). Kinetic studies over the temperature range 25-75 degree C yields activation energies (in Kcal/mole) for aspartic acid (20.8), phenylalanine (28.7), glutamic acid (32.5), and alanine (32.4). Racemization rates increase with hydroxide ion concentration but not with protein concentration. Acetylation of amino groups prevents lysinoalanine formation but not racemization, permitting studies which distinguish between effects of these two alkali-induced reactions.

AN - 15451635; 266377 AB - When freshly prepared homogenates of etiolated pea (Pisum sativum L. cv Calvedon) subhook segments were fractionated by high speed centrifugation, the enzyme catalyzing the conversion of 1-aminocyclopropane-1-carboxylic acid (ACC) to ethylene was found associated with the particulate fraction. However, on aging the homogenates at 5 degree C prior to fractionation, 50 to 75% of the enzyme activity partitioned into the soluble fraction; this solubilization led to a highly activated enzyme form. Both the particulate and soluble enzyme exhibited non-linear substrate saturation kinetics and were inhibited to similar extents by ascorbic acid, ADTA, CoCl sub(2) and limiting oxygen. However, they differed in their response to incubation with n-propylgallate, dithiothreitol, CaCl sub(2) and 100% oxygen. Calcium stimulated only the particulate form and increased both the "low k sub(m)" for ACC from 2.99 to 5.58 mM and apparent Vmax from 88 to 285 nl/mg protein/h.

Moths were ca. 60% larger and the females laid ca. twice (1:1.9) as many eggs on a soy flour-wheat germ diet as on Cyperus rotundus plants, but wing length was only 22% longer. Unfed males mated no more than once each 24 h and deposited seven spermatophores during an average life time of 9 days. By day 4 or 5 of life, one-third of the males could not fertilize more than an average 23% of the egg load of a virgin female. Female mating could delayed 4 days after emergence before fecundity was affected. Females mated twice if newly emerged males were presented daily for 2 or 3 days. Unmated females deposited an average of ca. 27 eggs; mated females deposited 5 to 10 times as many eggs, with egg viability varying from 80 to 90%. Clipping two-thirds to three-fourths of one forewing to prevent flight did not reduce fecundity. JF - Environmental Entomology AU - Frick, KE AU - Wilson, R F AD - Southern Weed Sci. Lab., Agric.

AN - 15444738; 258383 AB - In the Yakima Valley of Washington there are two distinct strains of the green peach aphid (GPA), Myzus persicae (Sulzer): a holocyclic yellow morph and an anholocyclic green morph. These two distinct color morphs were maintained for over 20 generations in the greenhouse on a number of different host plants. In tests with non-viruliferous GPA feeding on diseased sugarbeet, Beta vulgaris (L.), or hoary cress, Cardaria draba (L.) Desv., the holocyclic strain was slightly more successful in transmitting beet western yellows virus (BWYV) to an indicator plant, shepherdspurse, Capsella-bursa pastoris (L.) Medic., than the anholocyclic strain. However, viruliferous GPA of the holocyclic strain was less successful in transmitting BWYV to indicator plants after first feeding on noninfested sugarbeet or hoary cress plants (83 and 66% efficiency, respectively), whereas the anholocyclic strain was able to transmit BWYV at lesser rates (98 and 96%, respectively). These differences may have arisen because of selective factors resulting from the different winter hosts normally associated with the two populations.

AN - 15442588; 259124 AB - Isoelectric focusing in horizontal thin layers of polyacrylamide gel in combination with selected synthetic substrates and inhibitors was used to analyze the alkaline midgut proteinases from larvae of 5 species of stored-product insects. Partially purified proteinases from the black carpet beetle, Attagenus megatoma , had isolectric points ranging from 3.9 to 9.0. About 15 proteinases were detected when focused gels were incubated on a casein-agar layer. A complex of 17 anionic and cationic proteinases was found in the hide beetle, Dermestes maculatus . Six trypsin-like and two chymotrypsin-like enzymes, one aminopeptidase, and one carboxypeptidase were demonstrated with artificial substrates and inhibitors. Two distinct, strongly anionic proteinases (pI 2.8 and 2.9) were found in Tribolium castaneum , while a single cationic proteinase was demonstrated in the furniture carpet beetle, Anthrenus flavipes . Compared with the other species, there were no strong proteinases in the midguts of larvae of the Indian meal moth, Plodia interpunctella . The use of horizontal isoelectric focusing in polyacrylamide gel for the analysis of proteinases in insects is discussed. JF - Comparative Biochemistry and Physiology.

AN - 15440246; 251484 AB - Sherwood B. Idso, says that burning fossil fuels will cause no climatic problem. He suggests that either the climatologists are wrong or they have left something out of their predictive models. Idso draws his conclusions from "real world" research at Phoenix, where for the past 12 years, he has measured incoming solar and thermal radiation using variations in dust and water vapor as substitutes for the projected CO sub(2) increase. He has concluded that doubling atmospheric CO sub(2) will change surface air temperature less than natural climatic variability. He says, "There is essentially no danger of significant climatic warming due to any forthcoming increase in atmospheric CO sub(2) concentration, even for a tenfold increase. Hence, not only is an increase in CO sub(2) not detrimental, it is desirable, for a doubling or tripling of the atmospheric CO sub(2) content could increase global agricultural productivity by fully 20 to 50 percent."

AN - 15439856; 251498 AB - Estimates of mineralization of soil organic N are often needed to predict N fertilizer requirements of crops. G. Stanford and his collaborators developed laboratory techniques to estimate potentially mineralizable N (N sub(o)) in soils and a rate constant for mineralization (K). Their techniques have been used to estimate N mineralization in the field. This study reports the use of stepwise multiple regression techniques to estimate N sub(O) from soil pH, organic carbon concentration, total N concentration, and soil taxonomy. The regression equation for N sub(O) accounted for 83% of the variation of N sub(O) for 90 samples from 67 soils representing eight soil orders. The regression equation for k accounted for 40% of the variation in the rate constant k for 61 samples from 43 soils. These results should aid in the estimation of N mineralization in cases where laboratory measurements of N sub(O) and k are not available.

AN - 15426171; 239824 AB - Three recently developed tests used to indicate virulence were performed on 34 strains of Y. enterocolitica . Agreement in virulence or nonvirulence prediction was found in (a) 29 of 31 strains when tested for calcium growth dependency at 35 degree C; (b) all 34 strains when tested for the ability to autoagglutinate in tissue culture medium at 35 degree C; and (c) among all 34 strains when tested for the presence of a 40-48 Mdal plasmid using a modification of the Hansen and Olsen method for plasmid analysis. The autoagglutination assay is recommended for testing potential pathogenicity of foodborne isolates. There are probably several virulence-determining factors for Y. enterocolitica , and no one in-vitro test will suffice. The analytical procedure described herein can be used to detect plasmids ranging in size from approximately 2 x 10 super(6) to 3 x 10 super(8) daltons.

AN - 15426149; 239239 AB - A study was conducted to determine losses and distributions of nitrogen (N) and phosphorus (P) in runoff waters and sediments from heavily fertilized agricultural watersheds during both the growing and nongrowing seasons. The study was done on two small watersheds having well-drained, fine, sandy loam soils. Runoff was measured continuously and sampled proportionately during 50-60 events over a 2-year period. Ninety nine percent of the sediment loss over the period occurred during 11 months; 64-86% occurred during a single storm in April when no crop canopy was present. This event was associated with rainfall probabilities rising rapidly toward a primary annual peak for East Lansing, Mich. A second storm of equal magnitude in August was associated with a secondary annual peak in normal rainfall for this location.

The containers were located on residential blocks within a substandard urban area of New Orleans, Louisiana, USA. The regular addition to the containers of 1 or 2 predator larvae resulted in an average control of prey emergence of 65 and 82%, respectively. The data indicated that while substantial mortality among the predators occurred, due to cannibalism or other natural factors, the overall control obtained for both treatment levels was 74%. Cannibalism among predators appeared to play a minor role in determining the degree of control obtained.

AN - 15412607; 239301 AB - The role of herbaceous vegetation in the nutrient cycling regimes of adjacent upland (oak-hickory) and floodplain (silver maple) forests was studied at Robert Allerton Park in E-central Illinois. Net annual production of the upland spring ephemeral group was 68.5 g/m super(2) and was dominated by Claytonia virginica) and Dicentra cucullaria ; production by the summer herb group was 24.5 g/m super(2) and was dominated by Impatiens pallida). Net production by all floodplain herbs was 88.8 g/m super(2) and was affected by a summer flood which induced early senescence in some species. Net uptake of N, P and K by upland spring ephemerals was 10.6, 1.6 and 18.9 kg/ha, respectively, and by summer herbs, 6.3, 0.84 and 15.1 kg/ha, respectively. Uptake of these elements by floodplain herbs was 16.6, 3.6 and 20.3 kg/ha, respectively. The nutrient dynamics of floodplain forests are probably more strongly affected by annual flooding patterns and sedimentation than by herbaceous nutrient uptake. In general, the rapid decomposition of herbaceous litter provides a source of nutrients whose availability for plant uptake is intermediate to that of aqueous inputs and litter from overstory species.

Time of arrival at the droppings and peak densities of 3 species, Hister coenosus Erichson, Hister incertus Marseul, and Xerosaprinus orbiculatus (Marseul), indicate that these may be important predators of immature stages of the horn fly, Haematobia irritans (L.). Saprinus pennsylvanicus (Paykull) and Xestipyge conjunctum Say were found infrequently at very low numbers throughout the study. It is unlikely that these species are effective control agents of the horn fly. Seasonal distribution and abundance varied among species.

AN - 15408802; 231568 AB - In 1980, applications of fenvalerate (0.11 kg/ha) to flowering alfalfa either at night or in the morning caused no apparent damage to colonies of honey bees, Apis mellifera (L.), located adjacent to the treated field. However, fenvalerate appeared to temporarily repel honey bees: bee visits to alfalfa flowers were 70% less on the afternoon after the fenvalerate applications than on either the afternoon preceding the sprays or on the 2nd afternoon after the sprays were applied. Neither spray treatment (morning and night) appeared to adversely affect visits of wild bees to alfalfa flowers. Also in 1980, 5 weekly applications of fenvalerate at dusk did not noticeably affect nuclei containing 3-4 frames of honey bees and brood which had been placed in cages to pollinate alfalfa. In July 1981, fenvalerate applied at the rate of 0.4 kg/ha to a 1.6-ha field of flowering alfalfa at daybreak did not seriously affect 10 colonies located at the edge of the field.

AN - 15403776; 217963 AB - As the need to supply answers to this country's hazardous waste disposal problems becomes steadily more urgent, there is mounting interest in the feasibility of composting as a means of detoxifying, degrading or inactivating hazardous waste constituents. The aerated pile composting method developed by the U.S. Department of Agriculture at Beltsville, Maryland in the 1970's has been used extensively to transform sewage sludge into compost that is free of noxious odors and pathogens, and can be used safely and beneficially on land as a fertilizer and soil conditioner. Parr et al. discussed the various factors such as moisture, temperature and C:N ratio that can most significantly affect the composting process and which must interact favorably to sustain rapid and effective aerobic/thermophilic composting.

AN - 15389372; 210969 AB - Eleven to eighteen days after removing either one protozoan, Trichonympha agilis , or all protozoa except T. agilis from worker termites of R. flavipes these termites were able to incorporate similar amounts of radioactivity from sodium (1,2- super(14)C)-acetate into lipids as were normally faunated termites. However, the super(14)C incorporated into lipids by the abnormally faunated termites was not distributed among lipid components in the same way as in the normally faunated termites. The quantity of some lipids synthesized, as judged by the incorporation of radioactivity from ( super(14)C)-acetate into lipid carbon, was lower in R. flavipes termites lacking certain symbiotic protozoan species than in normally faunated termites. Using the same criteria phospholipids were synthesized equally well by normally faunated R. flavipes and those termites lacking some or all normal protozoa. Coptotermes formosanus worker termites lacking either the protozoan Pseudotrichonympha grassii , all symbiotic protozoa, or all bacteria, were able to incorporate radioactivity from (1,2- super(14)C)-acetate into lipids. C. formosanus termites lacking either hindgut bacteria or one or all symbiotic protozoan species did not synthesize lipids from acetate to the same extent as did normal termites. Evidently hindgut bacteria and symbiotic protozoa not only function to break cellulose down to acetate but also affect in some way the conversion of acetate into most lipids. JF - INSECT BIOCHEM.

These treatments were compared with a standard rangeland insecticide treatment with 560 ml of 95% technical malathion per ha, and compared with no treatment. Each plot was 2,332 ha, and each treatment was replicated four times. The high level of N. locustae caused significant reductions in grasshopper densities during the season of treatment (1975). A panzootic among grasshoppers caused by the fungus Entomophthora grylli Fresenius occurred early in the second season and reduced the potential for expression of subsequent effects by N. locustae . Nevertheless, the high level caused significant reductions, and the low level appeared to cause slight but not significant reductions in grasshopper densities during the two subsequent seasons (1976 and 1977). Parasitism of grasshoppers by entomophagous flies and nematodes decreased sharply in malathion plots, but tended to increase in N. locustae and untreaed plots.

AN - 15377664; 208931 AB - Native Drosophila were periodically captured, dusted with a micronized fluorescent dust and released during the summer of 1977 at two locations near Raleigh, North Carolina. Two or three days after each release, flies were collected in baited traps placed at regular intervals along a transect (800 m or 1,200 m long) centered on the point of release. Recapture data provided estimates of the shape of the distribution of released flies as well as the dispersal rate of Drosophila , in particular D. melanogaster and D. simulans . Simultaneously collected unmarked flies provided estimates of natural population densities and effective sizes during the summer and early fall.Movement of marked flies averaged 150 m per day with a variance of around 20,000 m super(2). The observed distribution of a large sample of marked flies appeared to fit a Brownian motion model, in spite of a tendency for Drosophila) to aggregate in moist, shady spots. The density of flies varied over the 4 mo tested, ranging from near zero to roughly 2-3 flies per 100 m super(2) for both D. melanogaster) and D. simulans at the two experimental sites.

AN - 15375478; 208813 AB - Results of laboratory and field studies showed that adults of Anthonomus grandis grandis Boheman, captured in Leggett traps baited with gradlure or collected from surface leaf litter and duff during the non-cotton season (September to April) of 1978-1979 and 1979-1980 in a subtropical area near Brownsville, Tex., were unique in that they remained physiologically active throughout the winter. Boll weevils were trapped even on days when minimum temperatures were as low as 1.5 degree C. Females caught during the fall remained sexually mature, mated, and stored viable sperm in their spermatheca, but egg hatch was not observed under laboratory conditions (artificial diet) during ca. 2 months in the winter. However, these females oviposited fertile eggs when fed for at least 10 days with fresh cotton squares. Catches of teneral weevils were very common throughout the winter, an indication that weevils could remain reproductive through the winter when proper nourishment was available from cotton regrowths or seedling plants in unattended or abandoned fields.

AN - 15375116; 206300 AB - The primary objective of land treatment of industrial wastes is to utilize the chemical and microbiological capabilities of a soil to enhance the chemical and/or biological detoxification, degradation, and inactivation of a given waste, thereby rendering it less hazardous and less toxic to human and animal health. Unfortunately, industrial wastes in many cases have been disposed of on land with little consideration as to the principles and parameters involved. This paper discusses a number of important principles that should be considered for safe and effective land treatment of industrial and hazardous wastes. It also suggests some strategies that may be useful in developing acceptable management practices for land treatment systems.

AN - 15371450; 195113 AB - Although beta -lactoglobulin ( beta -Lg), the major whey protein of bovine milk, has no known membrane-associated function, it shares certain structural characteristics with membrane proteins. Both average hydrophobicity and the ratio of charged to hydrophobic residues lie between those for intrinsic and extrinsic membrane proteins. The circular dichroism (CD) spectrum of native beta -Lg shows much less helical structure than predicted by analysis of the amino acid sequence by use of the Chou-Fasman rules. When beta -Lg is synthesized in vitro in the presence of microsomes, its signal peptide is cleaved while the protein is passing through the membrane, and beta -Lg than assumes its native conformation. In a microsome-free system, the signal peptide is not cleaved and is not accessible to enzymatic attack after the protein folds. These observations led the authors to look for possible interactions of beta -Lg with phospholipids. Although no complex formation has been detected between native beta -Lg and egg phosphatidylcholine, dimyristoyl phosphatidylcholine (DMPC), or dipalmitoyl phosphatidylcholine (DPPC), solvent-denatured beta -Lg readily interacts with each of these lipids.

Caffeine produced a small decrease in growth, while reducing ochratoxin production as much as 98%. Theobromine had relatively little effect on growth or ochratoxin production. Screening of caffeine for its effect on the growth of a number of Aspergillus and Penicillium species indicated that caffeine may have biological activity against a variety of mycotoxigenic molds.

The principles of co-composting toxic chemical wastes with the municipal wastes and the design and management of composting systems are discussed. The criteria for site selection are summarized and it is shown that soils have a high capacity to degrade chemical wastes and a strong buffering capacity.

The filter achieved almost complete removal of 122 000 faecal coliforms per 100 ml and 8.63 mg per litre total phosphorus. The nitrogen content of vegetation harvested from the filter bed increased from a constant 4 per cent during the first 3 years of operation to 5.1 per cent as more nitrogen became available for plant uptake, and net uptake was replaced by net nitrogen release. The advantages of peat in this application include its retention of permeability, its high cation exchange capacity and its capacity to be replaced when saturated. The blue grass planted on the bed played an important role in overall nutrient removal.

The characteristics of hazardous wastes and the soil environment are reviewed and some factors affecting degradation of wastes in soil are described. The decomposition of different residues is discussed in terms of their nitrogen content, and the effect of added nitrogen, and the concept of nitrogen requirement value is defined. The effects of toxic substances on soil micro-organisms is considered with particular reference to the known effects of pesticides, and the relation between loading rate and application frequency relative to the probable period of soil anaerobiosis is shown.

AN - 13852588; 706538 AB - Foraging group size and temporal/spatial patterns of activity by reproductive female Rocky Mountain elk (Cervus elaphus nelsoni ) and black-tailed deer (Odocoileus hemionus columbianus ) were related to seasonal changes in forage availability and quality during May through October. Seasonal patterns of daily activity regimes indicated that food selection, consumption, and processing were the major factors constraining elk and deer habitat use. Both elk and deer reacted similarly to these constraints. Seasonal activity patterns and foraging group sizes indicated that searching effort increased as forage quality decreased, and that in September-October foraging emphasis shifted from individual plants to microhabitats where plant phenology was delayed relative to average conditions.

AN - 13773365; 639014 AB - The developmental rates of the egg, larval and pupal stages of the dusky sap beetle (Carpophilus lugubris ) reared on artificial diet at 21 degree C were 4.04, 22.27, and 9.2 days, respectively, a total of 35.5 days. The mean lifetime of adult females was 263 days, or about 110 days longer than previously reported. Its population growth statistics were as follows: intrinsic rate of increase = 0.340 female/female/week, generation time 12.20 weeks, and net reproductive rate = 63.1 female/female/week. Field studies established that the sap beetles can successfully invade ears of corn throughout the season in the absence of corn earworms (Heliothis zea ). However, more sap beetles were found in ears infested with corn earworm than in ears not so infested. Eggs of Geocoris sp. were more abundant in infested ears with corn earworms and sap beetles than in uninfested ears; however, adults of Orius tristicolor (white) did not display such a preference.

AN - 13771298; 636457 AB - Exposure of azadirachtin to sunlight caused a rapid decrease in antifeeding potency against newly emerged first instar fall armyworm, Spodoptera frugiperda , as compared to unexposed azadirachtin. Acetone solutions of azadirachtin exposed for seven days gave more than a 50 percent reduction in activity while azadirachtin exposed for sixteen days gave complete reduction in activity with destruction of the compound. p-aminobenzoic acid, a uv-absorbing additive, gave slight protection to azadirachtin form photodegradatin. Azadirachtin, mixed with various plant oils, was exposed to sunlight for two weeks. Bioassay of these mixtures showed that neem, angelica, castor, and calamus oils provided moderate protection (< 25 percetn) to azadirachtin from degradation by sunlight. JF - J. ENVIRON. SCI. HEALTH.

AN - 13758302; 627968 AB - Parental, F sub(1), F sub(2), and backcross generations of tomato (Lycopersicon esculentum) Mill.) lines Morden MEL 2668170G (MEL) and "Walter" (WA) were screened as seedlings for resistance to verticillium wilt (Verticillium dahliae Kleb.) race 2. Disease reaction means, based on the number of leaves and cotyledons with symptoms 5.5 weeks after inoculation, were 2.7 for MEL and 4.6 for WA. Resistance in MEL appeared to be recessive with narrow sense heritability estimated at 0.25 or less. Disease severity was sometimes inadequate to avoid the selection of escapes in advanced generations. Analysis of F sub(3) progenies, however, indicated 3 genes or less might be involved. Results suggest race-2 resistance can be maintained in advanced generations by the elimination of highly susceptible plants and by progeny testing to insure recovery of the most resistant individuals rather than escapes.

A. Host variables. AN - 13728537; 596529 AB - Vesicular-arbuscular (VA) mycorrhizal fungi often have a positive quantitative effect on growth and vigor of plants. Indeed, the purpose of much mycorrhiza research is to utilize these fungi to accelerate growth or to produce plants of acceptable size using less resources, such as fertilizer. Therefore, evaluation of response by plants that have formed VA mycorrhizae (VAM) usually involves size determinations. Frequently the differences between inoculated and non-inoculated plants are obvious and can be recorded photographically, but for experimental puroses, one must also quantify and document such differences. The authors intent in this chapter is to discuss the different parameters that can be measured to evaluate plant responses to VAM, and the experimental factors affecting these responses and their interpretation, under controlled greenhouse as well as field conditions.

AN - 13711371; 587078 AB - Escherichia coli concentrations of bottom sediment and overlying water were derermined from a variety of streams in southwestern Idaho by a one-step most probable number technique. Results show E. coli concentrations of bottom sediments to be from 2 to 760 times greater than from the overlying water. E. coli concentrations of bottom sediment were found to be resuspended following disturbance simulation and a rainstorm event, contributing to pollution of the overlying waters. It is, therefore, suggested that microbial analysis of bottom sediments be considered a part of water-quality evaluations for rangeland streams.

AN - 13680093; 552633 AB - An overstory or slash pine on the Palustris Experimental Forest in central Louisiana decreased herbage production as early as plantation age 17 for longleaf pine and plantation age 10 for slash pine. During the years of 1960 through 1975, from 80 to 85% of the variation in herbage production could be explained by the equations, Y = 2094.75 + 10.10P - 106.98BA for longleaf pine and Y = 1606.18 = 14.03P - 88.10BA for slash pine, in which Y = herbage production in kg/ha, P = April through October precipitation in cm, and BA = pine basal area in m super(2)/ha. Pinehill and slender bluestem were the principal herbaceous species on nonforested plots in 1975, while a mixture of forbs, pinehill bluestem, and other bluestem grasses were most common on forested plots. The study quantifies data on herbage production and botanical composition over time and suggests ways for the forest manager to evaluate timber and herbage tradeoffs.

AN - 13676526; 551786 AB - Diammonium phosphate (DAP), air-dropped in early autumn 1974 to contain a wildfire on the San Joaquin Experimental Range in California, applied high levels of nitrogen and phosphorus to foothill annual grassland. The DAP drop and fire provided 4 treatments for the study--unburned + DAP, burned + DAP, burned and unburned (control). In the first year both of the DAP treatments, with yields of more than 12,000 kg/ha produced twice that of the unburned (control). First-year forage yields for the unburned and burned plots were not significantly different. The second year the burned plot yielded almost twice that of the unburned. The second year, the unburned + DAP plot produced about 4200 kg/ha, the highest yield of all 4 plots, and significantly higher than the burned + DAP plots.

AN - 13676209; 553535 AB - Net carbon dioxide assimilation rates (P sub(N)) were measured for individuals from two Texas honey mesquite Prosopis glandulosa) Torr. var. glandulosa ), populations grown under controlled water stress, temperature, and light treatments. Maximum P sub(N) observed for the various tests ranged from 0.69 to 0.82 mg multiplied by m super(-2)s super(-1). Net assimilation rates were significantly lower in the west Texas population than in the east Texas population under high and low water stress. Maximum P sub(N) at 1.35 mmol multiplied by m super(-2)s super(-1) photon flux density were reached under low water stress at 20 degree C and 30 degree C for east and west Texas populations, respectively. The response of P sub(N) to light was similar to responses reported for other C sub(3) species; and 81 to 99% of the variability in the data was accounted for by using a hyperbolic light response model. High temperature and water stress treatments also caused substantial decreases in the estimated theoretical maximum net assimilation rates. Finally, the light saturation point of mesquite varied depending on population and water stress. JF - Journal of Range Management AU - Hanson, J D AD - USDA, Agr. Res.

AN - 13675864; 551609 AB - The transfer of organic pollutants into the atmosphere is discussed from the standpoint of mechanisms involved, factors influencing rates of volatilization, and progress in developing models for predicting transfer rates. The volatilization rate of soil-incorporated chemicals is controlled by vapor pressure of the chemical in soil and by its rate of movement of the soil surface by diffusion or by a combination of diffusion and convection in evaporating water. Vapor pressures of organic chemicals are greatly decreased by their interaction with soil mainly due to adsorption. The magnitude of the adsorption effect depends upon the nature of the chemical, its concentration, the soil water content and soil properties, such as organic matter and clay content. Vaporization of chemicals in soil or from disposal sites covered with soil can be estimated from considerations of the physical and chemical factors controlling concentrations at the soil surface and most models developed to estimate volatilization rates are based upon equations describing the rate of movement of the chemical to the soil surface by diffusion and/or convection.

AN - 13675828; 553026 AB - Changes in aspen reproduction and undergrowth production and composition were recorded over a 3-year period following clearcutting. Aspen suckers increased from 2,300 per hectare prior to cutting a maximum of 44,000 per hectare the second post-cut year, and dropped to approximately 25,000 per hectare by the third year. Undergrowth production on the cut units increased from 1,013 kg/ha prior to cutting to 3,000 kg/ha after three growing seasons; production on the uncut control areas increased from 1,199 kg/ha to 1,539 kg/ha during this period. The significant increase in undergrowth is attributed to the reduction in competition from the removal of the aspen overstory. Clearcutting appeared to increase the proportion of shrubs in the undergrowth and decrease the proportion of forbs. A similarity index comparing the cut and uncut areas suggested that the greatest change in species composition occurred the first year after cutting, with gradual return towards the precut conditions.

In vivo protein labeling yielded polypeptides of 58,000 to 62,000 daltons, suggesting cleavage of signal sequences from the precursors. Further cleavage is apparently required to separate the alpha and beta polypeptide sequences which are known to form disulfide-linked 53,000 to 58,000 dalton species in the ( alpha beta ) sub(6) holoprotein.

AN - 13635538; 527716 AB - Footrot and foliar phases of the disease caused by P. medicaginis var. pinodella in peas (Pisum sativum L.) were studied. Major objectives were to develop repeatable inoculation procedures and to identify pea lines resistant to footrot and foliar infection. All tests were conducted under controlled environmental conditions. Fungal spore concentrations and plant age at inoculation were important for identifying differences in disease reactions among lines. Significant differences in reactions to footrot were obtained among lines when pea seeds were immersed for 5 min. in inoculum adjusted to 1 x 10 super(4) spores/ml, planted in a sterile soil mixture, and scored 10 days later. There was no significant correlation between footrot and foliar disease scores, indicating that different genetic factors may control reactions to the two phases of the disease.

AN - 13635102; 529070 AB - Agricultural use of pesticides has remained high for economic reasons. Because aquatic species may bioaccumulate pesticides more readily than terrestrial organisms, there has been much concern about pesticides in agricultural runoff. Despite this concern, there presently is little relevant information for use in making accurate predictions of the impact of specific pesticide amounts in agricultural runoff on water quality at some point downstream. There is a compelling need for fundamental research on the physical, chemical, biological and hydrological processes that regulate pesticide behavior not only in agricultural and aquatic habitats, but also during transit between the two. Further, data are needed concerning pesticide toxicity potential as a function of the aquatic physical and chemical regime, and concerning population recovery dynamics as a function of pesticide concentration and species stress.

AN - 13622838; 513420 AB - The Westport Land Records Project is an interdisciplinary effort by a group of University of Wisconsin (Madison) researchers in collaboration with the Dane County Regional Planning Commission, the Wisconsin State Cartographers Office, and the Economics and Statistics Service of the USDA. The project is concerned with the development of an automated land data base for the township of Westport in Dane County. General project objectives include examination of the usefulness, reliability, cost and required accuracy of a survey-based cadastre, the feasibility of developing such a system within a local government setting, and the determination of public attitudes towards land information held by the populace within the study area. The immediate project tasks are (1) to develop compatibility among spatial resource records by integrating survey control with existing source data and (2) improve physical data handling techniques.

AN - 13622763; 507973 AB - The effects of transcontinental (interstate) transport and transoceanic shipment were determined on microbiological and shelf-life characteristics of beef tongues and livers. These variety meats were evaluated for both microbiological and shelf-life characteristics following slaughter in Guymon, Oklahoma, USA. The samples were then frozen and sent by refrigerated truck to storage facilities in Jacksonville, Florida, USA. Further microbiological and shelf-life evaluations took place prior to overseas shipment at the University of Florida and following overseas shipment at The Institute CIVO-Technology, TNO, Zeist, The Netherlands. Aerobic plate counts (APCs) at 35 degree C for beef tongues showed a significant (P < 0.05) decrease following overseas shipment. Similar results were noted for beef livers. For both organs, the surface thawing in Florida, required for sampling, did not appear to affect the final bacterial counts. The 20 degree C APCs for beef tongues revealed a significant (P < 0.05) decrease following interstate transport but not transoceanic shipment. The 20 degree C APCs for beef livers did not differ significantly during the entire transportation period. The colour differences noted during transport of the products were probably the result of freezing and not of the actual shipping and storage conditions.

AN - 13621257; 513553 AB - The soybean mosaic virus (SMV) susceptible soybean (Glycine max (L.) Merr.) breeding line D60-9647 was inoculated with SMV-1 at five different stages of development in each of 4 years to observe the effects of SMV in an area where vector dissemination of SMV is not apparent. Mean reduction in seed yield over the 4-year period was 12%. There was a large increase in percent mottled seed following SMV inoculation with the highest percentage resulting from inoculation at the V7 stage of development. Percent of seedlings showing virus symptoms (15%) was highest from the inoculation at the V7 stage. Percentage of seed germination was reduced from 95 to 88%. Another study was conducted in which closely related SMV resistant and susceptible lines were compared using seed harvested from susceptible lines which had been inoculated with SMV. The results indicate that under conditions similar to those in which the first study were conducted, seed from SMV infected plants can be utilized for planting with no undesirable effects.

The loblolly population west of the Mississippi River, in the loess hills along the east side of the flood plain of the Mississippi River, and the western Florida Parishes of Louisiana proved to be consistently more resistant to fusiform rust (Cronartium quercuum f.sp. fusiforme ) than loblolly pine from the rest of the study area. This resistance was stable in all three plantings. Less stable was the occasional resistance found in individual half-sib families scattered throughout the generally susceptible population. About 2.5 percent of the families from the generally susceptible population were resistant in all three planting locations.

AN - 13600364; 491216 AB - Pure culture inoculum (mycelium plus substrate) from each of six ectomycorrhizal fungi, all six fungi combined, and pine duff was mixed separately with 1:1 vermiculite-peat moss growing medium at 10 and 20 percent by volume, dispensed into 410 ml containers (Spencer-Lemaire Rootrainers)), and seeded with Pinus ponderosa or P. sylvestris . Seedlings were grown in a greenhouse at Bottineau, North Dakota, for 6 months, overwintered in the greenhouse, planted on a native grassland site at Denbigh, ND and observed for 5 years. In the greenhouse, percent of seedling short roots ectomycorrhizal with Thelephora terrestris , Pisolithus tinctorius , mixed pure cultures, and pine duff ranged from 21 to 60. Cenococcum geophilum failed to synthesize mycorrhizae, and Rhizopogon roseolus and Rhizopogon roseolus and Suillus granulatus synthesized ectomycorrhizae on less than 5 percent of seedling short roots. Survival, stem diameters, current years height increment, and biomass of P. ponderosa were increased after 2 and 3 years for seedlings inoculated with pine duff, R. roseolus , or S. granulatus ; similar increases were obtained for P. sylvestris seedlings that were inoculated with pine duff.

AN - 13600197; 491086 AB - Patterns of litterfall and decomposition in adjacent floodplain and upland forest communities were investigated at Robert Allerton Park in central Illinois. Floodplain and upland litterfall were similar in terms of dry weight and most nutrients, and were higher than litterfall for other similar forest communities. Leaf litter decomposed rapidly at the floodplain site, and substantial amounts of nutrients were transferred to the mineral soil prior to flooding. This may have been advantageous to individuals of the forest community because the mineral soil nutrient pool was enriched prior to removal of forest floor litter by spring floors. Dry weight loss from leaf litter in the upland forest was much slower than for floodplain litter. JF - Forest Science AU - Peterson, D L AU - Rolfe, G L AD - USDA For.

Bees made an average of 3.8 cells per nest and provisioned cells exclusively with pollen from the Compositae. Approximately 12% of all offspring were killed by either the clerid predator Trichodes ornatus or the chalcid parasite Melittobia sp. An additional 30-38% of offspring failed to complete development to the adult stage. Most of this immature mortality occurred during the overwintering and incubation stages. The sex ratio of the populations varied between 1.4 to 1.8 (male/female). Nests with 3 or fewer cells had a lower percentage of male offspring than all other nests combined. It may be possible to increase the percentage of female bees by decreasing the depth of the nesting hole.

AN - 13573541; 459944 AB - The grape growers and winemakers of the eastern United States are faced with several endemic and potentially damaging fungal diseases of the vine. Four of the more serious ones and the type of damage are: powdery mildew which may reduce crop, weaken vines through premature defoliation, and introduce a musty taste to the wine; black rot which reduces crop size; downy mildew which, sporadically, may reduce crop size, defoliate vines, and prevent proper maturity of grapes for wine; and bitter rot which may introduce an unacceptable flavor to the wine. Temperature differences along the East Coast affect to some degree the distribution of these diseases. Control is through application of appropriate fungicides on established schedules. Alternate control is through use of disease-resistant cultivars.

The tumor-inducing (ti) plasmid from the crown-gall pathogen Agrobacterium tumefaciens may be a source of a selectable gene for higher plant systems and possibly of other vector elements such as a replicator sequence, specific "end" sequences to facilitate integration, and plant promoter sequences. Transformation experiments with the isolated tumor-inducing plasmid DNA have produced putative transformants, but stable transformants in which Ti DNA sequences can be detected reproducibly have not been reported. Agrobacterium -mediated transformation using strains with foreign genes inserted at specific sites in their tumor-inducing DNA offers a new approach to the genetic engineering of certain higher plants.

AN - 13549730; 436246 AB - The recent history of catastrophic disturbances in forests was reconstructed at Mount Rainier National Park. Basic data were ages of trees based on ring counts of early seral conifer species and maps of age-class boundaries from field work and aerial photographs. Maps illustrate age classes of the forests and show disturbances from fires, snow avalanches, and lahars (volcanic mudflows). Fires are by far the most important major disturbers, followed by snow avalanches and lahars. Fires over 250 ha in size are called fire events. Burns over 1000 ha, which may have been one fire or a series of fires within a short time, are called fire episodes. JF - Quaternary Research AU - Hemstrom, MA AU - Franklin, J F AD - USDA For.

AN - 13549456; 436264 AB - Twenty-seven fungus species with diverse sporocarp-host associations were tested for ectomycorrhiza formation with seven Pacific Northwest conifers: Pseudotsuga menziesii, Tsuga heterophylla, Larix occidentalis , Picea sitchensis, Pinus contorta, P. ponderosa , and P. monticola . The fungi varied widely in their ability to form mycorrhizae with the various conifers but can be placed into three groups: fungi with wide ectomycorrhizal host potential, low specificity, sporocarps usually associated with diverse hosts in the field, fungi with intermediate host potential yet specific or limited in sporocarp-host associations, and fungi with narrow host potential, only able to form ectomycorrhizae with a specific host species or species within a genus and likewise limited in their sporocarp association. Numerous fungi which produce sporocarps exclusively in association with specific hosts were able to form well-developed ectomycorrhizae with one or more nonassociated hosts. Thus, specific sporocarp-host association does not necessarily limit mycorrhizal associations with other hosts. JF - Forest Science AU - Molina, R AU - Trappe, J M AD - USDA For.

AN - 13548160; 436434 AB - An analysis of the 51-year herbage yield series from the Manyberries Range Experimental Farm in southeastern Alberta showed that there was a slight dependency between current year's herbage yield and previous year's yield. The analysis showed that the conditional probability of a below-average yield following a belowaverage yield year was about the same as the unconditional probability of having a below-average yield in any given year. The conditional probability of an above-average yield following a year with a below-average yield was significantly below the unconditional probability of having an above-average yield in any year. The probability of an above-average yield following a year with an above-average yield was significantly greater than the unconditional probability.

AN - 13547043; 444897 AB - SSelected physical, chemical and bacteriological qualities of stream water entering and leaving a campground were examined during the summer of 1978 to investigate the influence of recreational use. Water samples were collected and analyzed at approximately biweekly intervals, and also three times daily before and after the Memorial Day, Fourth of July, and Labor Day weekends. Chemical and physical quality remained unchanged and densities of indicator bacteria in surface water were not significantly increased by recreational use of a campground equipped with modern sanitation facilities.

AN - 13545696; 436233 AB - Eight hardwood forest species were grown in fumigated soil without vesicular-arbuscular mycorrhizal (VAM) fungi or in soil infested with either Glomus fasciculatus (GF), a mixture of Glomus mosseae and G. etunicatus (GM), or a mixture of several fungal species in the genera Glomus and Gigaspora (GG). With the exception of sugar maple, VAM development increased stem weight of seedlings by 2- to 80-fold over nonmycorrhizal controls. Root weight of all seedlings was increased by 4- to 70-fold by VAM. Generally, GF stimulated more seedling growth than other fungi. Laboratory assays of the root samples indicated that feeder root infection by the fungi varied from 55 to 85 percent, but generally there were no significant differences among the VAM treatments within tree species. Differences among hosts were observed in the amount of hyphae, arbuscules, and vesicles produced by the fungi, which could be attributed to growth and development characteristics among hosts and VAM fungi.

AN - 13541483; 441313 AB - Potentially there are several chemical and hydrologic problems associated with placement of acid spoil materials. The rationale for a deep placement well below the soil surface, and preferably below a water table, is to prevent or minimize oxidation of pyrite to sulfuric acid and associated salts by reducing the supply of oxygen. If, however, substantial sulfuric acid or associated salts are already contained within the spoil because of present or previous mining, handling and reclamation operations may actually increase the rate of acid and salt leaching. Specific placement of acid- and salt-containing spoil should be aimed at preventing contact with percolating water or rising water tables. JF - RECLAM. AND REVEGET. RES.

AN - 13540007; 436772 AB - The addition of gramicidin-A to reconstituted purple membrane, significantly inhibits light-induced proton movement. Kinetic analyses indicate that the treatment decreases the initial proton pumping rate (R sub(o)), alters the interdependence (m) between the pumping process and its associated H super(+) leak path (k sub(L)-k sub(D)), but has no detectable effect on the proton permeability associated with phospholipid bilayers in the dark (k sub(D)). These results suggest that gramicidin-A, under the experiments conditions, interacts directly with bacterirhodopsin in the membrane.

AN - 13535966; 435771 AB - Eighteen years of herbage yields of range grasses and concomitant precipitation and temperature fluctuations were examined with correlation and regression techniques. Antecedent precipitation was the dominant factor influencing yield of perennial herbaceous species, while both temperature and precipitation were important for prediction of yield of downy bromegrass, a winter annual. Total yield of the herbaceous community was closely correlated with precipitation received during the September to June period (r = 0.92); however, September to March precipitation was also highly correlated (r = 0.89). These correlations provide timely and useful estimates of native range production of eastern Oregon ranges. Sixty to 92% of yield variation was accounted for by the regression models for 9 of the 12 species or species groups examined.

Conservation tillage has proven to be a very effective technique to control erosion. However, for conservation tillage to be effective, crop residues must be on the surface after planting. Thirty-five percent of Illinois ' erosive rainfall occurs from April 15 to July 1, between planting time and the development of a crop canopy. Crop residues intercept raindrops before they hit the soil surface and dissipate much of their energy. Two dominant conservation tillage systems are used in Illinois: the chisel flow and the no-till system. Other agricultural erosion control methods are contour farming, terracing, and grass waterways. Contour farming on slopes of 2.1 to 7.0% can result in a 50% reduction in soil loss. Terracing, particularly parallel tile outlet terraces, store runoff behind terraced ridges and slowly release the water through an inlet pipe. Grass waterways convey excess water runoff across fields to safe outlets, although grade stabilization structures are often needed to control flow velocity and, thus, erosion. Streambanks and construction sites are potential sediment producing areas. If vegetation is not feasible to stabilize the site, rock riprap can be used to provide protection. Streambank erosion can also be reduced through proper maintenance, such as by regularly removing debris.

Snow covered area was used as a predictor variable to forecast both short-term and seasonal snowmelt runoff volumes. The Leaf-Brink Subalpine Water Balance simulation model was adapted to use snow covered area as an input parameter to predict residual volume runoff. Areal snow cover was also used in a statistical model to forecast runoff and is compared to current water equivalent index methods of forecasting. Currently available LANDSAT imagery is of sufficiently quality and resolution for accurate snow mapping by photo interpretative means. Delay in image delivery, occurrent of cloud cover, and a nine-day interval between satellite coverage diminish to a significant extent the amount of reliance one can place in using snow cover as a forecast parameter. A statistical regression model relating snow cover to seasonal volume flow, and a computerized simulation model which provides short-term and seasonal forecasts using snow cover as an input variable indicate about a 10% reduction in average forecast error can be realized through use of satellite derived snow cover in forecast procedures. A significant drawback to using snow covered area exclusively to make streamflow predictions is the lack of applicability prior to commencement of the main snowpack recession which normally occurs after May 1. Water management decisions frequently need to be made late in March and in April, necessitating streamflow forecasts before snowpack depletion gets well underway.

In six test runs , influent TKNs were 171-240 mg per liter; influent COD, 1039-1649 mg per liter. In the process the waste is nitrified in the aerobic zone and then returned to the anoxic zone for denitrification. The higher the rate at which the aeronic mixed liquor is returned to the anoxic zone, the greater the degree of nitrate removal, which in these runs ranged from 0.13 - 0.17 mg N per mg per day. A high influent COD produced better nitrate removal. The high rate and degree of nitrate removal in the first stage was enhanced in the laboratory system by limiting the rate of aeration in the last aerobic stage and sparging the anoxic zone with nitrogen gas. Although this would not be practical on a commercial scale, several possible alternatives are suggested.

Sheet, rill, and wind erosion continue to be a major national problem. Cropland loss of soil by sheet and rill erosion is estimated to be 1.7 billion tons annually. In 19 states the average cropland erosion rate exceeded 11.2 tons/ha. Fifty percent of all sheet and rill erosion occurs on cropland. Cropland without adequate conservation treatment has an average annual soil loss of 1.5 billion tons, more than eight times the amount on adequately protected land. Pastureland, rangeland, and forest land account for another 1.7 billion tons of soil lost by sheet and rill erosion. The annual erosion rate on pastureland in four states exceeded 11.2 tons/ha. Very steep areas make up one fourth of the total pastureland, but account for 62% of the pastureland erosion. The rangeland sheet and rill erosion rate in four states is more than 11.2 tons/ha. Areas with limiting soil conditions make up one third of the total rangeland acreage , but account for two thirds of the rangeland erosion. About 17% of the nonfederal forest land is grazed and erodes at six times the rate of ungrazed forest land. Wind erosion in the 1976-77 winter blowing season damaged 3.2 million ha of land in the Greater Plain States. The average annual loss due to wind erosion exceeded 11.2 tons/ha on cropland in 3 states and rangeland in 4 states.

When low levels of secondary amines were added to tap water, nitrosamines were detected, indicating that the water had nitrosating ability. Experimental evidence obtained by adding sulfamic acid, piperidine, and sodium sulfite to the water showed that the nitrosamines did not form on the resin. It was proposed that the trace nitrosamines may have been produced from the reaction of nitrates (present at levels up to 10 micrograms per liter N02-N) with an oxidizing agent, such as chlorine, and amines in the water.

Definitions and concepts of terms such as antimicrobial agent, antibacterial agent, disinfectant, and sanitizers are discussed from both a regulatory and scientific perspective. Quantitative tests for determining antibacterial activity of textiles usually involve sterilization of fabric, inoculation with a microorganism, and determination of bacteria remaining by wash-recovery or colony-count under a low-power microscope. Most qualitative tests for antibacterial activity are based on the ability of the agent to diffuse off the fiber into an agar medium. Most antifungal tests consist of inoculation of fabric, then inspection for visual growth of fungi after varying periods of time.Microbial ecology of the skin-clothing interface differs in everyday environments and situations from environments conducive to growth of microorganisms and cross- infection ; predominant bacteria and fungi and microbial population on different parts of the body are discussed in this context. Microorganism persistence on textiles is influenced to some extent by fiber type. Recent studies show that synthetics retain more odor-causing bacteria, and that dermatophytic fungi are more persistent on synthetics than on natural fibers; persistence time of pathogenic bacteria,on natural and synthetic fibers is dependent on relative humidity and method of fabric contami nation.Newer and commercialized processes for producing antibacterial fabrics durable to laundering are evaluated, and frequently-used disinfectants and sanitizers for textiles are stressed. Various techniques for affixing such agents to fibers are listed, and requirements for producing effective antibacterial and antifungal fibers for particular end-uses are enumerated. Some novel and recent uses for antibacterial fibers, such as water disinfection and air purification, are also mentioned.

This paper summarizes Phase I of the appraisal of this program, concentrating on soil and water conservation, and excludes wind erosion, water quality, changes in productive capacity, wildlife habitats, and offsite impacts. Information was collected from 171 counties in 46 states, 5% of all counties , for a total of 60,836 cases. Overall results show that the ACP is doing a very good job in meeting its stated purposes, but effectiveness can be improved with planning and greater use of scientific tools such as soil maps and the Universal Soil Loss Equation. More than 52% of shared cost erosion control projects were installed on land with low erosion rates, less than 5 tons per acre per year; only 27% on land eroding at high rates, 5-14 tons per acre per year. Almost 63% of irrigation water practices were applied to lands receiving 4 ft or less per acre per year; 34% to lands receiving 4-8 ft per acre per year; and 4% to lands receiving 8 ft per acre per year or more. The 4% accounted for over 33% of total volume of water conserved. As the capacity of impoundments increased, costs per acre foot of storage capacity declined and costs per acre increased.

Phase I covers erosion rates on cropland, range, forest, and pasture. Phase II covers erosion rates on stream banks, gullies, roads, and construction areas. Data collection was completed on October 1979 from 72,500 randomly selected sites on nonfederal land in all states except Alaska and including Puerto Rico. Total national erosion on nonfederal land is estimated at about 4.8 trillion mg annually, itemized as follows: cropland, 37.6%; range, 26.5% forest, 8.3%; pasture, 6.6%; stream bank, 10.6%; gullies, 5.7%; roads, 3.2%; and construction, 1.5%. Expressed at 1000 mg per year, the erosion losses for 610 million ha of nonfederal land are cropland, 1,786,676; pasture, 314,192; range, 1,263,218; forest, 396,875; stream banks, 501,763; gullies, 270,619; roads, 153 ,003; and construction, 72,529. Erosion data are also presented for streams, gullies, roads, and construction for each state.

The first uses a sediment sampler to provide an estimate of both sediment concentration and total runoff. The second system uses a sediment sampler to give an estimate of sediment concentration and a supplementary instrument to give the total runoff estimate. Criteria for choosing a sampler for a particular application are capacity, sample size and type, accuracy, reliability, cost, and hydraulic head. Geib multislot divisors and storage tanks are used to estimate total sediment yield, on an event basis, from small plots. Pomerene wheels and H flumes are used in small basins. When discrete samples are required for soil erosion process research, or from medium to large basins, pumping sediment samplers are used. The sampler intake point is located downstream of a turbulent section of flow or a depth integrating tube is used to obtain representative samples. The flow measuring structures used with pumping samplers are either sloping crest Crump weirs or H flumes with 14% sloping drop boxes.

Part of this change stems from modernization of land and farm management practices which call for more irrigation water. China also gives high priority to the use of water for navigation and has stepped up measures to improve drainage and control flooding. Although China has vast water resources, many rivers are not located near irrigable land, and their high sediment contents often cause flooding. During the last 30 years, many physical structures have been built to help alleviate some of the problems. More work is needed on water reuse and spills. The rich sediment deposits of the Yellow River have been used for farmland. Until watershed erosion is controlled, the use of reservoirs for reducing flood peaks and trapping sediment will be limited. Mechanical parts are rapidly worn by the high sediment content of the water. Several critical sites along the Yellow River have been targeted for major erosion control programs. Revegetation has aided eroded areas that were destroyed by the rapid harvesting of forests. More collaboration between and research from national government, local government and academic organizations on erosion problems is needed. Human waste is often applied to vegetable crops grown near the cities; animal manure is composted with other organic materials and applied to mostly rice and cotton crops. Chemical fertilizers are being used increasingly where available. More progress in the better use of natural resources in China is expected through exchange of information with other countries.

The characteristics of seasonally grazed pasture are influenced as much by vegetative cover and wild-life activity as by cattle grazing. Thus the concentrations of chemical constituents in runoff from ungrazed grassland were greater than those in runoff from grazed pasture. The faecal coliform counts showed characteristics of wildlife faeces, so that recommended bacteriological water quality criteria may be inappropriate for characterizing pasture runoff and other non-point sources of potential pollution.

A novel destruction technique for treating potentially toxic pollutants was evaluated using tannery unhairing effluent. The process is based on a free-radical, auto-oxidation mechanism of breakdown of the waste. The free radicals are produced by passing the solution under pressure through an orifice. The collapse of gas bubbles in cavitation can develop very high local temperatures, which can lead to ionization effects, and the production of hydroxy-free radicals and peroxides. Tannery unhairing waste was treated in a pilot plant scale auto-oxidation unit. This waste is highly alkaline with a pH generally higher than 11, and has a chemical oxygen demand greater than 50,000 mg/l, consisting largely of protein and sulfide. In static tests, auto-oxidation effectively and rapidly removed sulfide from the waste. Removal of chemical oxygen demand, nitrogen, and suspended solids was considerably less effective. Combining the auto-oxidation with ultraviolet light and a hydrogen peroxide addition improved the chemical oxygen demand very little.

AN - 733489853; 16661704 AB - Ammonia accumulation and photosynthetic rate inhibition took place when spinach leaf tissue was supplied with methionine sulfoximine (MSO), an inhibitor of glutamine synthetase. This effect was observed in the absence of significant inorganic nitrogen reduction or an exogenous source of ammonia. Both the time lag prior to the initial photosynthetic rate decrease and the rate of that decrease depend on the O(2) and MSO concentrations supplied to the leaf tissue. However, the total rate of ammonia accumulation was similar at both 20% and 2.2% O(2). The decline in photosynthetic rate was not caused by stomatal closure but may be a result of ammonia toxicity. The data point out the importance of glutamine synthetase in preventing the poisoning of leaf metabolism by ammonia generated internally through processes not involved in net nitrogen assimilation. The rapidity of the action of MSO in suppressing photosynthesis was unexpected and should not be overlooked in interpreting data from other experiments involving that inhibitor. MSO shows promise as a tool for investigating C-N flow, particularly during photorespiration.

Snowmelt runoff contributes about 75% of the water supply in this area, and this type of data has been collected manually for about 40 years. At each SNOTEL site there will be sensors ro measure snow water content, accumulated precipitation, and temperature. These automated snesors will eliminate the need for manual measurements at more than 500 of the 1600 data sites in the snow information network. Meteor trails are used to transmit data from remote sites to a master station. This real time system is capable of collecting and transmitting data from as many as 1000 remote sites and from as many as 16 digital or analog sensors at each site. A performance test held in February 1979 was successful.

In the one-bath process, a water-soluble complex of the organic agent was prepared from a carbonatozirconate or zirconyl chloride and applied to fabric by a conventional pad-cure procedure. In the two-bath process, fabric was treated successively with a solution of zirconyl acetate and a solution of a salt of the antimicrobial agent. The fabrics were tested for activity against the bacteria Staphylococcus aureus and S. epidermidis and the fungus Trichophyton mentagrophytes. Fabrics given a two-bath treatment with pyrithione (1-hydroxy-2-pyridinethione), tetracycline, or oxytetracycline retained excellent bacteriostatic activity after fifty launderings, and the one treated with pyrithione still had excellent antifungal activity after twenty launderings. Antimicrobial activity imparted by some of the one-bath treatments was initially extremely high but was less durable to laundering.

The issue of cumulative impact will be raised increasingly by land managers over the next decade. This and other management problems can be best addressed from an understanding of the overall movement and storage of sediment in drainage basins. Basic understanding of geomorphic systems will also be advanced by more analysis of sediment budgets and routing. JF - Journal of Hydrology.

The relative importance of each process is determined by an interaction between climate, soil, geology, topography, and vegetation. A change in any of these components can increase or decrease the rate of erosion. The key to successful management of erosion is the ability to 1) identify potentially äerodible sites, 2) correctly assess appropriate activities at those sites, and 3) have a political/regulatory system that allows for the exclusion of hazardous sites from land treatment. äSteepland erosion is controlled most effectively - both in physical and economic terms - by preventative land-use practice rather than corrective action JF - Journal of Hydrology.

The program is identifying critical erosion and animal waste problem areas where soil conservation and water quality plans will be implemented. The program has developed assessment procedures and best management practices so that landowners can prepare their own individual plans. An information management system has been developed to help identify critical areas, to aid in the refinement of the implementation program, and to report progress. As part of this information system a mapped inventory of managerial and physical information on State farmland has been developed. Through the use of color codes, the maps provide an instantaneous overview of the conservation treatment status of any watershed. Maryland has received tentative Environmental Protection Agency approval of its agricultural 208 plan.

The Cost of Land Application of Wastewater (CLAW) model was used to simulate land treatment systems under a variety of scenarios. Results showed that rapid infiltration systems are the least costly of the systems examined, followed by overland flow, center pivot irrigation, and solid set irrigation, in that order. Land application systems are relatively capital intensive with a four-to-one ratio of capital to operation and maintenance costs. Introduction of net crop revenue, except for rapid infiltration systems, further reduces the variable system costs. Conventional advanced wastewater treatment (AWT) systems were also simulated. The AWT system is generally more expensive than land application. Sensitivity analysis indicated that extending the irrigation season and the application rate as much as possible lowers the amount of land and need for irrigation equipment. Future research needs include better data on costs, crop responses, and offsite impacts. These issues need to be resolved before land application is likely to gain widespread acceptance as an advanced wastewater treatment method.

The acreage of cropland and forest land is decreasing while the acreage of pastureland, native pasture, rangeland, and urban land is increasing. The Corn Belt, Lake States, Northern Plains, and Delta States have the largest acreages of soils well suited for agriculture. Moisture supplies tend to be less in soils west of the Mississippi. Soil temperatures are of a mesic regime in the central part of the United States. Better methods are needed to characterize soil quality. Soil erosion by water is measured primarily by the Universal Soil Loss Equation. The wind erosion equation estimates the susceptibility of soil to wind erosion. Networks are needed for erosion measurement in all major management and land use conditions in the country. Information is needed on the effects of soil erosion on soil productivity to justify the use of private and public funds for soil conservation and for establishing objective standards of tolerable soil loss. Data is needed on the water holding capacity, tilth, and nutrient content of soils to assess the suitability of soils for crop production. A basic strategy for collecting information and an integrated system to handle research data on soils must be developed. Other research priorities are the development of models to predict the effects of global forces on United States agriculture and the assemblage and maintenance of integrated land information systems for all parts of the United States.

Aquatic stages of Chaoborus punctipennis) (Say), Coelotanypus tricolor (Loew), and Chironomus attenuatus (Walker) constituted over 90% of all dipterans collected. Diptera were distributed throughout the reservoir and constituted the single most important component of the macrobenthos. Certain species were ubiquitous while others were restricted by depth or substrate. Changes in water temperature, dissolved oxygen, and water level controlled emergence, repopulation and larval migrations. Populations showed mid-winter highs and summer lows with some species having as many as four generations per year. JF - Journal of freshwater ecology.

One spray of these fungicides, suitably timed to host and rust development, gave satisfactory control in moderate rust epidemics. Good control was obtained in most schedules of two sprays applied at a 7-20 day interval during the period from primary infection to early logarithmic increase of rust.

CGA-64251, methfuroxam, and triadimenol appear to be more potent against bunt than hexachlorobenzene.

When fed exclusively on a diet of all life forms of Panonychus citri (McGregor), none of the mature, F sub(1) A. hibisci) females deposited eggs, moreover, complete immature mortality occurred at 32 and 35 degree C. Prior to their deaths, individuals of both sexes exhibited a dark-red occlusion of varying sizes within the alimentry tract near the distal end of the opisthosoma. Pollen fed A. hibisci populations attained their optimum growth and reproductive rates at 35 degree C. The intrinsic rate of natural increase, r, was found to be 0.29 individuals/female/day and the population possessed the capacity to double every 2.38 days. Constant temperature and r are closely correlated (r super(2) = 0.891) and the relationship is a curvilinear regression. JF - Z. ANGEW. ENTOMOL.

However, the only published records of interactions between them are a trapper's description of wolves killing a black bear of unknown age and sex and a report by Joslin (1966) of a black bear killing an adult female wolf near a den of pups. In addition, C. C. Dickson (pers. comm.) found that wolves killed an immature black bear in northern Ontario on 18 May 1979. The authors report on interactions between wolves and bears observed during concurrent telemetry studies of both species in northeastern Minnesota between 1969 and 1979. Territories of wolves and bears commonly overlapped in this area. JF - Journal of Mammalogy AU - Rogers, L L AU - Mech, L D AD - USDA North Central Forest Exp.

AN - 15477530; 276454 AB - Biological nitrogen fixation is second only to photosynthesis as the most important biochemical process on earth. Biological fixation contributes an estimated 140 million metric tons of nitrogen annually to the earth, of which 80% is fixed via symbiotic associations and 20% by free living organisms. The biological cost of fixed nitrogen is substantial, about 2.5% of the primary photosynthesis on land (6). To produce an equivalent amount of nitrogen through the Haber-Bosch process would require about 9.25% x 10 super(12) cubic feet of natural gas. The high cost of nitrogen via biological fixation and chemical fixation makes it imperative that we understand and improve biological nitrogen fixation. Legumes are a major source of protein, oil, and forage for human and animal consumption and are among the world's most important crops. About 85% of nitrogen fixed in agricultural soils comes from pulse and pasture legumes. Because of great diversity in plant characteristics, legumes are widely adapted. One of the primary reasons for this wide adaptation is the association of legumes with the Rhizobium bacteria. When effective, this association enables the plant to fix gaseous N sub(2) and depend less on soil nitrogen. In numerous instances, however, the association is ineffective and becomes a detriment to the plant. This paper explores nodulation as a disease and delves into the host-symbiont relationship.

AN - 15467451; 273740 AB - In 1978 and 1979, the effects of brown spot caused by Septoria glycines on the yield components of Williams soybeans at three canopy levels were investigated. In 1978, seed weights of plants inoculated with S. glycines were significantly reduced. Seed weight reductions in the upper, middle, and lower canopy levels were 8, 11, and 16%, respectively, when compared with uninoculated plants sprayed with benomyl. In 1979, seed weight reductions of 8 and 5% in the lower canopy of naturally infected and inoculated plants were significantly difference from seed weights of inoculated plants sprayed with benomyl. Number of pods per plant or of seeds per pound did not differ significantly, except for the greater number of seeds per pod in the upper canopy of inoculated plants sprayed with benomyl in 1978.

AN - 15467183; 274534 AB - The rice root aphid, R. rufiabdominalis , overwintered as viviparae on underground parts of Vermillion wheat (Triticum aestivum ) and Hudson barley (Hordeum vulgare ) at Urbana, IL, under relatively stable temperatures and transmitted the barley yellow dwarf virus. Hudson barley, Michigan Amber wheat, and Dubois oats (Avena sativa ) were good virus sources and indicator test plants. In parallel tests, R. rufiabdominalis and R. padi were equally able to transmit two vector nonspecific isolates. Both aphids, however, failed to transmit the Macrosiphum avenae specific virus isolate. Like the other two isolates, this one was readily transmissibly by Sitobion avenae . This brings the total number of aphid species known to be vectors of barley yellow dwarf virus to 18. JF - Plant Disease AU - Jedlinski, H AD - Agric. Res. Serv., USDA, Univ.

Runoff was incubated for up to 5 wk on Kuhlman's medium. Colonies of Fomes annosus developed from runoff collected from 2 hemlock and 1 spruce, and colonies of Armillaria mellea from 12 hemlock and 8 spruce. Most A. mellea cultures had morphological characteristics commonly associated with single spore isolates. Because collections were made in March and April, 3-4 mo after sporophore production by A. mellea , basidiospores of A. mellea apparently survived the winter on the outer bark of sampled trees.

A total of 55,155 living trees in 173 windbreaks in 41 counties was examined. Based on occurrence of sporocarps, infected trees were found in 40 counties and in 90% of the windbreaks. Mean incidence of infected trees was 5.5 plus or minus 0.4% (0.95 confidence limit). A mean of six sporocarps was found per infected live tree, and more than 98% of the sporocarps were associated with branch stubs on the bole or major lateral branches within 3.6 m of the ground. About 110,000 trees of an estimated 2 million living F. pennsylvanica in Nebraska have sporocarps; an even greater number are infected with F. fraxinophilus .

AN - 15453445; 268279 AB - In the Pine Plains of southern New Jersey, dominant P. rigida sprouts reached heights of 5 to 6 m at 50 years of age; in plots cleared of existing trees, P. rigida seedlings reached about the same height in 22 years, and planted P. strobus seedlings 5 to 9 m in 17 years. Results substantiate other studies that repeated wildfires, not soils, are the primary cause of the low stature of P. rigida in Plains areas, and that genetic composition of the P. rigida is a contributing factor. To maintain typical Plains sprouts less than 2 m tall, as well as many of the associated non-arborescent species, fires that kill back woody stems are needed at about 10-year intervals. JF - BULL.

Although N sub(2)O emissions from the native grassland were small, they were substantially larger than earlier estimated from uncultivated soils. The losses accounted for about 10% of N inputs from atmospheric deposition and N sub(2)-fixation, which represented a significant N-loss mechanism that had not been recognized. Nitrous oxide losses from similar sites treated with urea to simulate ungulate urine deposition were about three times greater than from untreated soils, but still amounted to only 0.6% of the added N.

AN - 15447475; 263238 AB - The kinetics of P desorption for several soils was investigated at different water/soil ratios, during a short period of time, so that theresults could be related to P release from agricultural soil to rainfall and runoff water. For all soils the logarithm of P release (P sub(d)) was linearly related to the logarithm of contact time (t) at any given water/soil ratio (W) and P amendment and to logarithm of W at any given contact time and P amendment. The amount of P released was also directly propotional to the amount of desorable P (P sub(o)) in the soil initially. The following simplified empirical model was developed to describe the desorption of soil P, P sub(d) = KP sub(o)t super( alpha )W super( beta ), where K, alpha , and beta are constants. The simplified model gave a reasonably good description of P desorption from five southwestern soils and provided similar values of the constants K, alpha , and beta , for each soil, over a range of experimental conditions.

AN - 15445336; 257074 AB - Members of various fungal taxa and Actinomycetes have been shown to degrade lignin at least partially. The white-rot wood-decomposing Basidiomycetes completely metabolize the complex polymer, exhibit the highest reported rates, and are the most studied. Evidence indicates that their degradation of lignin involves oxidative, nonspecific reactions, but the nature of the catalysts and the reactive species remain undefined; the catalysts have not been separated from living cells. Culture conditions optimal for lignin metabolism by white-rot fungi have been described, and several potential applications of whole ligninolytic cultures have been explored preliminarily: (a) partial delignification for the production of cellulosic products (biomechanical pulping, bio-bleaching); (b) conversion of lignocellulosics (improving ruminant digestibility, cultivating edible mushrooms) into feed and food; and (c) treatment of lignin-derived wastes (decolorizing, removing BOD, COD). The possibility to biomodify by-product lignins to yield valuable polymeric or low molecular weight chemicals has not been approached experimentally, but is another area of potential application. Improved waste treatment processes might well be the first intentional application of bioligninolytic systems.

Both proteins were toxic to the cabbage looper, Trichoplusia ni , but only the 65,000-alton protein was toxic to larvae of the mosquito, Aedes taeniorhynchus . Biochemical comparisons based on isoelectric focusing and peptide mapping by two-dimensional gel electrophoresis indicated that the two toxins were distinctly different.

AN - 15426473; 243785 AB - Acetylene reduction rates, N sub(2)(C sub(2)H sub(2)), were obtained to estimate nitrogen fixation by several introduced and native range legume species. The N sub(2)(C sub(2)H sub(2)) fixation rates of excised root segments with attached nodules were measured in the field for legumes from two mountain grassland sites, one native sagebrush-dominated site, and three cultivated former big sagebrush study sites. Sampling was conducted in the driest part of the growing season. Even during this high stress period, nodules were present and active in some legume species. Medicago sativa) plants were particularly notable because of their capability of being nodulated and ability to reduce acetylene in dry soils when other legumes were not active. In addition, under the most favorable environmental conditions in this study, nodules from M. sativa reduced acetylene most actively at a rate of 26.2 mu moles ethylene/h/g nodule fresh weight. Although nodulation was generally less successful in New World than Old World lupine species, Lupinus mutabilis was capable of reducing acetylene at a rate of 4.97 mu moles ethylene/h/g nodule fresh weight, even in a severely water stressed environment.

AN - 15426159; 239189 AB - The movement of the synthetic pyrethroid insecticides decamethrin, cis and trans isomers of cypermethrin, and cis and trans isomers of permethrin and their degradation products DCVA (cis, trans-3-(2,3-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylate) , PBAI (3-phenoxybenzyl alcohol), and PBAc (3-phenoxybenzoic acid) was examined in a Hagerstown silty clay, silty clay loam, and a Tifton loamy sand. Movement in both soil columns and soil thin-layer chromatographic (TLC) systems was compared. Decamethrin, cis- and trans-cypermethrin, and cis- and trans-permethrin were immobile in all soils. PBAI was only slightly mobile in each of the three soils examined. Both DCVA and PBAc were mobile in each of the three soils examined, and the separation of the cis and trans isomers of DCVA was observed in some soils. Both DCVA and PBAc were less mobile in acid soils than in an alkaline soil. Soil TLC provided an exceptionally comparable picture of soil movement of the compounds examined when compared with the unsaturated soil columns.

AN - 15424912; 239180 AB - The recently-developed synthetic pyrethroid insecticides appear to have a potential for widespread use in cotton (Gossypium hirsutum L.). Thus, their persistence and movement under field conditions should be evaluated to identify any possible environmental hazards. Permethrin (3-phenoxybenzyl ( plus or minus )-cis, trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate) (1:1 cis/trans) was applied to cotton at a rate of 0.112 kg/ha on 10 separate dates each year in August and September of 1976 and 1977. Concentration measurements of the cis and trans isomers on cotton plants and leaf litter, and in soil and runoff (sediment + water) indicated that permethrin disappeared about 3-6 months after the last application, confirming permethrin's relatively short persistence compared with organochlorine insecticides. Under a wide range of rainfall and runoff conditions, permethrin concentrations and losses in runoff were low. Even under severe runoff conditions permethrin concentrations generally were not great enough to be harmful to aquatic species.

AN - 15413861; 239460 AB - Habitat type (identified by plant indicators) and elevation were compared as alternative bases for stratifying forest land into breeding zones or seed zones for reforestation. The comparison was based on the assumption that the genetic variation in an indigenous population of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) reflects the adaptively important environmental variation in the area inhabited by the population. Relative values for habitat type and elevation were then estimated by the amount of genetic variation explained by each in classification and regression models. Elevations, habitat types and tree genotypes were sampled in a 6100-hectare watershed in the Cascade Range of western Oregon. Parent trees (190) were from 114 locations (sources) in the watershed. Genetic variation was estimated by the performance (in 15 traits) of 3-year-old seedling families (190) grown in a common garden. Neither elevation nor habitat type were completely satisfactory for classifying environments into zones, in that elevation explained only about 56 percent of the source-related genetic variation, habitat type only about 35 percent.

In most cases, there appeared to be little difference among the three chemicals. Reduction of root and top growth (dry weight) for each plant species was linearly related to increases in soil chemical concentrations. Growth reduction at a given chemical concentration varied among crop species, with alfalfa being the most susceptible and corn the least susceptible. Chemical concentration in plant tissue increased almost linearly with increasing soil concentrations.

AN - 15411542; 239601 AB - S. bovis and M. elsdenii were grown in continuous culture with maltose as the limiting substrate at dilution rates of 0.36, 0.22, and 0.12 h super(-1). After each steady-state turnover, the pH was decreased by adding concentrated HC1 to the medium reservoir. Relative counts of the two species at each dilution rate indicated that when the pH was high (6.6 to 6.0), higher dilution rates selected for a higher ratio of S. bovis to M. elsdenii . At intermediate pH (6.0 to 5.4), higher dilution rates once again selected for greater numbers of S. bovis in relation to M. elsdenii , but the increase in S. bovis numbers was much less at the 0.36-h super(-1) dilution rate. Decreasing the pH below 5.4 caused the ratio of S. bovis to M. elsdenii to increase greatly, and no M. elsdenii cells were seen below pH 5.1. The ratio of the two species could be explained by their relative affinities for maltose if pH was greater than 6.0, but the lower relative numbers of S. bovis in the 0.36-h super(-1), intermediate-pH (6.0 to 5.4) incubations could not.

Ethylene was produced by Cylindrocladium both from actively growing mycelium (direct) and nonenzymically from culture filtrates (indirect). Both direct and indirect systems were light mediated, and appeared to involve a fungal metabolite, a flavinlike compound (FLC), either contained in the mycelium or secreted into the medium.

The first account of C. jejuni isolation from red meats-lamb carcasses-is reported. Recovery of Campylobacter from meat surfaces was tested as follows: selective agar plates consisted of tryptic soy agar, 5% lysed defibrinated horse blood, 10 mg/L vancomycin, 2500 units/L polymyxin B, 5 mg/L trimethorprim lactate, and 15 mg/L cephalothin (Keflin; VPTK plates). These VPTK plates were incubated at 35 degree C for 72 hr in a gas atmosphere of 5% O sub(2), 10%CO sub(2), and 85% N sub(2). With these selective elements, recovery from meat surfaces inoculated with a calculated 32 Campylobacter) cells per cm super(2) was accomplished in 5 of 5 replicate tests.

Aggregation States. AN - 15405551; 216489 AB - Bovine beta sub(2)-microglobulin ( beta sub(2)-m), the light chain of the histocompatibility antigen, was isolated in crystalline form from colostrum. Sedimentation equilibrium experiments at pH 5.0 (0.08 M NaCl, 0.02 M sodium phosphate) at concentrations less than 0.3 mg/ml give M sub(r) = 11,800. From sedimentation velocity results, the authors conclude that bovine beta sub(2)-m is a much more symmetrical and compact molecule than either guinea pig or human beta sub(2)-m. At concentrations above 0.4 mg/ml under the same conditions, sedimentation equilibrium experiments show that a monomer to tetramer reversible self-association occurs. Also, the tetramerization increases with decreasing temperature. beta sub(2)-Microglobulin undergoes an irreversible temperature-dependent association to a much larger aggregate over a period of 7 days, as evidenced by sedimentation equilibrium and velocity results. The rate of this aggregation decreases as the pH approaches the isoelectric point (pH 7) from either side. Furthermore, circular dichroism measured at pH 5.0 under time-dependent aggregating conditions showed a marked increase in the percentage of disordered structure, leading to the conclusion that this effects is a denaturation phenomenon.

AN - 15402731; 227650 AB - Millions of hectares of pasture in the United States are lost to grazing each year because of dung accumulation and contamination. The population of dung beetles (Geotrupes spp.) in these pastures cannot adequately remove the millions of tons of livestock feces deposited daily throughout the country. However, the introduction of carefully selected species of foreign dung beetles could aid our native fauna in rapidly removing this dung from pasture surfaces. Three species of exotic beetles have already been released in Hawaii. The additional releases planned will provide a large enough complex of beetles in every major grazing area of the country to ensure rapid burial of livestock feces. Rapid removal of feces would return areas of pasture to grazing which normally would be lost because of contamination, recycle tons of nitrogen normally lost into the atmosphere, reduce the incidence of helminth parasites, and reduce pest fly populations on livestock.

AN - 15401170; 227173 AB - Soil compaction reduces plant growth in a variety of settings. In forest and range sites, amelioration of a compacted soil is usually impractical,therefore, emphasis has been given to minimizing and preventing compaction. To provide information on inherent soil compactibility, important factors related to susceptibility to compaction were identified by multiple linear regression of soil physical and chemical properties on Proctor maximum dry bulk densities. Analysis of moisture characteristic curves for 14 forest and range soils suggests that two range soils would occur in the field at water contents making them susceptible to puddling. About half the soils would remain at near optimum water contents for compaction for a long period of time under field conditions.

The objective was to quantify N sub(2)O losses during nitrification of banded anhydrous NH sub(3) under field conditions. Maximum N sub(2)O emission occurred shortly after initiation of rapid nitrification. Nitrites were present in the center of the NH sub(3) retention zone during N sub(2)O emission from the 110 and 220 kg N ha super(-1) treaments but not in the retention zone of the check or 55 kg N ha super(-1) treatments. Cumulative N sub(2)O emission increased as the NH sub(3) rate was increased, but was disproportionately large from the 220 kg N ha super(-1) treatments. However, even at the high N application rate, which was twice that recommended for the alternate winter wheat-fallow area of the Pacific Northwest, less than 0.1% of the applied N was recovered as N sub(2)O.

Aflatoxin levels in samples from the edges of the liver were 44% lower than averages of all the remaining samples, which were 25.0 ng B sub(1), 15.4 ng M sub(1) and 47.1 ng total aflatoxin/g; however, cross-sectional samples would give representative assay results. Lower total aflatoxin concentrations (16.0 ng 18.5 ng and 12.9 ng/g) were found for heart, spleen and muscle, respectively. The kidneys had the highest level of aflatoxin (145.9 ng/g) with M sub(1) levels (105.5 ng/g) 3.6 times the B sub(1) concentration (29.3 ng/g). In the other tissues, B sub(1) concentrations were 1.6-2.9 times greater than aflatoxin M sub(1).

AN - 15391636; 215335 AB - Corn kernels that exhibited bright greenish-yellow fluorescence (BGYF) under long-wave ultraviolet light were hand-picked from samples of yellow corn produced in eastern North Carolina. The BGYF kernels from 113 4-kg samples contained an average of 8665 parts per billion (ppb) aflatoxin compared to an average of 46 ppb in the non-BGYF kernels. A regression analysis between the ppb aflatoxin concentration and the wt % BGYF kernels in 2,304 4.5-kg samples produced the regression equation: ppb in sample + 197 (wt % BGYF). The correlation coefficient for the analysis was 0.90. Testing programs to reduce aflatoxin concentrations in purchased lots of corn based on either the either the BGYF method or the AOAC chemical assay method were compared. The average aflatoxin concentration in lots accepted by the AOAC method was 4 ppb, 10 ppb or 18 ppb when an acceptance level of less than or equal to 20 ppb, less than or equal to 50 ppb or less than or equal to 100 ppb, respectively, was used. For the BGYF method, the average aflatoxin concentration in accepted lots was 10 ppb, 16 ppb or 22 ppb when an acceptance level of less than or equal to 0.10% BGYF, less than or equal to 0.25% BGYF or less than or equal to 0.50% BGYF, respectively, was used. Approximately the same percentage of lots were accepted by both methods when either the low, medium or high acceptance level was used.

Compounds related to nicotine, the 2-cyano, 3-cyano and 4-cyanopyridines, the 2-vinyl and 4-vinyl-pyridines, pyrrole and pyridine, induced different patterns of germination responses among the different rust species. Pyrrolidine was not stimulatory. At high concentrations, 500 and 1000 mu 1 1 super(-1), nicotine induced extensive vacuolation in uredospores of all species except P. punctiformis . Some of the compunds related to nicotine also induced vacuolation. The ability of a compound to induce germination was not always correlated with ability to induce vacuolation. Chemically induced vacuoles absorbed neutral red, indicating an active metabolic uptake of the dye. JF - PHYSIOL. PLANT PATHOL. AU - French, R C AU - Wilson, CL AD - Plant Dis.

AN - 15389237; 210553 AB - Hexosamine accumulations in Puccinia striiformis were detected with histochemical and immunochemical techniques following inoculation on wheat isolines with and without Suwon 92 resistance. Urediospores stained intensely (except in germ pores) following treatment with a nitrous acid, 3-methyl-2-benzothiazolone hydrazone hydrochloride (MBTH), FeCl sub(3) reaction series used to quantitate hexosamine polymers. As spores germinated on either isoline the stain retained in the germ tube was light and localized in those hyphal tips in which growth appeared to be terminated. Subepidermal staining with both the hexosamine stain and FITC-conjugated anti-chitosan antisera was intense in inhibited hyphal tips in the resistant reaction. Staining also occurred in hyphae which grew beneath the epidermal layer in the susceptible reaction, but was generally not intense except in maturing urediospores. Since hexosamine polymers from chitosan inhibited the germination and growth of urediospores, the possibility that accumulations may be involved with both disease resistance and the termination of growth associated with spore maturation is discussed.

The seasonal N sub(2)-fixation pattern for the "Ransom" cultivar nodulated by R. japonicum) strain USDA 3I1b110, revealed that 65% of the total seasonal N sub(2) fixation occurred after N began to accumulate in reproductive tissue and that N sub(2) fixation during reproductive development and remobilization of vegetative tissue N met 83% and 17%, respectively, of the reproductive tissue N requirement. In a second experiment, "Davis" and Ransom soybeans fixed over 100% more N sub(2) during the growing season when nodulated by strain USDA 3I1b110 than when nodulated by strain USDA 3I1b110. High N sub(2)-fixation capability before reproductive development coupled with remobilization of vegetative tissue N was associated with the yield potential of Davis soybeans while high N sub(2)-fixation capability during reproductive growth was associated with the yield potential of Ransom soybeans. With either cultivar, nodulation by strain 3I1b31 restricted the amount of N stored in vegetative tissue for remobilization to developing seed.

AN - 15387486; 214634 AB - Florunner peanuts were grown in experimental plots with soil moisture and soil temperature modified during the last third of the growing period to produce drought, drought with cooled soil, irrigated and irrigated with heated soil treatments. Twice each week, beginning 97 days after planting, random samples were harvested and maturities of individual pods were determined without destroying pod integrity. The nature and quantity of the microflora associated with the pods and kernels were subsequently assessed. Drought and lower soil temperature resulted in maturity distributions containing higher proportions of immature pods. On peanuts with no visible damage to the pod or kernel, colonization by Aspergillus flavus was more frequent in immature than mature kernels. Drought stress increased the incidence of A. flavus and irrigation decreased it, except when soil temperatures were modified. A. flavus infestation was greatly increased at all maturity levels by pod damage.

AN - 15386261; 214733 AB - Preliminary field studies suggested evidence for resistance of certain corn hybrids to the preharvest infection of kernels by A. flavus and contamination of the kernels with aflatoxin before harvest. A major constraint in evaluating corn hybrids for resistance to the contamination has been the unusual heterogeneity associated with the toxin distribution. A few kernels containing high levels of toxin are routinely responsible for contamination of large sample lots. Extraordinary heterogeneity is also observed in toxin occurrence among fields within a region and among large geographic areas. Edaphic and climatic differences appear to render immature kernels susceptible to aflatoxin accumulation in a discontinuous manner. To reduce intrinsic variability and acquire definitive information on hybrid differences in susceptibility to contamination, several techniques have been developed including: (a) an increase in the number of regional test sites, (b) expansion of the sample sizes, (c) an increase in replication numbers, and (d) elevation of toxin levels in kernels by experimental treatments. Reduction of test variability has allowed for delineation of hybrid differences in aflatoxin resistance. In a diallel set study, genotypes have been identified with heritable qualities of reduced aflatoxin levels in developing kernels.

AN - 15384223; 214968 AB - Survival was studied of shell egg related microorganisms that were subjected to various combinations of water temperature, pH, and the presence of egg-washing detergents. Numbers of Salmonella typhimurium in buffered tryptic soy broth (BTSB) increased over a 7-hr period at pH 7 and 8 in water temperatures 35, 40, and 45 C. At pH 9 and 45 C, counts gradually decreased. At pH 10 and 11 counts always decreased, sometimes to 0, regardless of temperature. At 50 and 55 C, counts always decreased, sometimes to 0, regardless of pH. In commercial egg washing detergent (pH 11) at 50 C, survival of Salmonella, Citrobacter, Enterobacter, Proteus , and Klebsiella strains ranged from 0 to 90 seconds during several replicates. Survival times of most were extended somewhat in the presence of 1.0% suspended whole egg solids (e.g., Klebsiella - 3 min). Strains of Alcaligenes, Flavobacterium , and Pseudomonas demonstrated survival trends similar to those of the enteries: Flavobacterium survived the longest, almost 4 min either with or without egg material in the detergent solution.

AN - 15382616; 207356 AB - Cicer milkvetch (Astragalus cicer L.) does not flower in artificial environments that are used to induce flowering of the more commonly grown forage legumes. Therefore, the objectives of this study were to determine the vernalization and photoperiodic requirements of cicer milkvetch and to develop a practical chilling treatment for subsequent flowering in a greenhouse environment. Considerable variability exists among vernalized plants of the cultivar Lutana for photoperiodic response to flowering. Although only 30% of the plants flowered at the 13-hour photoperiod, a few plants flowered profusely. The highest percentage of plants flowering (98%) and the most profuse flowering (13.3 racemes/plant) occurred at photoperiods of 15 and 16 hours. JF - Crop Science AU - Townsend, CE AD - Res.

AN - 15377194; 196279 AB - Circular dichroism, differential scanning calorimetry and light-scattering measurements of ribulose 1,5-bisphosphate carboxylase (E.C. 4.1.1.39) from alfalfa, spinach and tobacco show: a) The conformation and thermal stability of the native carboxylases are sensitive to changes in pH and to activation of the enzyme with Mg super(2+) and CO sub(2). The helical content, denaturation temperature (T sub(d)) and specific enthalpy of denaturation ( Delta q) decreased with increase in pH. Addition of Mg super(2+) and CO sub(2) at pH 9 increased T sub(d) by 4 to 5C; at pH 7.5 the changes in T sub(d) were smaller. b) Addition of mercurials produced changes in conformation and thermal stability. The decrease in helical content of the enzymes with increase pH was enhanced by the addition of p-chloromercuribenzoate. At pH 9, addition of p-chloromercuribenzoate or of 1-(3-(chloromercuri)-2-methoxypropyl)urea decreased T sub(d) by 11.4 to 20.2 C and Delta q by 2.1 to 2.8 calories per gram. c) The spinach carboxylase undergoes the largest and the tobacco the smallest changes in conformation and thermal stability upon change in pH or treatment with mercurials. d) The calorimetric data suggest that the large and small subunits are heat denatured independently but at the same temperature. e) Light scattering measurements at pH 9 of p-chloromercuribenzoate treated tobacco enzyme showed that there is no dissociation into subunits upon heating to temperatures greater than T sub(d).

AN - 15371624; 192801 AB - Pyrolysis gas-liquid chromatography (PGLC) and statistical analysis employing stepwise discriminant analysis (SDA), were used to classify five species and varieties in the genus Bacillus . Nine strains were harvested, lyophilized, and pyrolyzed under replicate conditions. The combination of PGLC and SDA enabled classification of these selected varieties and species of Bacillus at 96% accuracy. Stepwise discriminant analysis of the same PGLC data discriminated (100%) B. cereus , a foodborne pathogen, from the remaining selected nonpathogenic bacilli when the two groups were compared. One particular elution peak resulting from the PGLC-SDA analysis was prominent in both discriminations reported. The PGLC and SDA method offers potential as an accurate, objective procedure for the discrimination of these selected bacilli. JF - Journal of Food Science AU - Stern, N J AD - USDA-SEA-AR, Meat Sci.

AN - 15369590; 194843 AB - A mouse virulence test for the O:3 and O:9 strains is described. The 50% lethal dose of the O:3 strains injected intraperitoneally with 2.5% mucin was about 10 super(7) colony-forming units. However, histological examinations showed that mucin allowed the growth of Y. enterocolitica) on the surface of the livers and spleens of the mice without internal lesions. The 50% lethal dose of the same O:3 strains injected intraperitoneally with 1 ml of 10% iron dextran in saline was about 10 super(5) to 10 super(6) colony-forming units, and the nonlethal infective dose with typical lesion development was 20 to 200 colony-forming units. The infected mice developed symptoms and extensive liver and spleen lesions which differed from those in mice infected intraperitoneally with the virulent O:8 strains. These results showed that the virulence of the O:3 Y. enterocolitica) strains can be measured by intraperitoneal injection with iron dextran. This procedure was used to test the virulence of food isolates, plasmidless strains, and the effect of growth temperature.

AN - 15367567; 192412 AB - Polysaccharides from 23 bacterial, fungal, and higher plant sources were tested for inhibition of systemic development of sugarcane mosaic virus (SCMV) in sweet sorghum (Sorghum bicolor "Rio"). Extracts from virus infected leaves were mixed with the polysaccharides and inoculated onto plants with an artist's airbrush. Polysaccharides from yeast cell walls and from Bacillus subtilis and Streptococcus pneumoniae Type III cell-free culture liquids inhibited SCMV-infection by 90-100% (symptom formation on treated plants compared with control plants inoculated only with SCMV) at concentrations as low as 250 mu g/ml. The other polysaccharides inhibited infection by 29% or less at concentrations as high as 2000 mu g/ml. Although several of the plant and microbial polysaccharides tested are antigenically related, no relationship between inhibitory activity and antigenic properties was apparent. JF - PHYTOPATHOL. Z.

AN - 15362086; 179791 AB - A 2 x 2 factorial experimental design consisting of four treatments (0, 2.5 mu g/g aflatoxin, 2.0 mu g/g ochratoxin A, and 2.5 mu g/g aflatoxin + 2.0 mu g/g ochratoxin A) with six replicates of 10 birds each was used to evaluate the synergism between aflatoxin and ochratoxin A. The size of the liver, spleen, pancreas, and proventriculus was significantly (p < .05) altered by the individual toxins; however, a synergistic effect on the size of these organs was not observed. The kidney and gizzard were sensitive to the coincident exposure to these mycotoxins and were significantly (p < .05) enlarged. The kidney was the most sensitive organ to the combined toxicity of aflatoxin and ochratoxin A, and nephropathy was the most important characteristic of this interaction. The synergism between aflatoxin and ochratoxin A significantly (p < .05) decreased growth rate and numerically increased mortality, demonstrating the enhanced toxicity of cocontaminated feed. Liver lipid levels were significantly (p < .05) increased by aflatoxin and decreased by ochratoxin A. The interaction of both mycotoxins on this parameter was significant (p < .05) and the combined effect demonstrates that ochratoxin A inhibited lipid accumulation normally induced by aflatoxin.

Other infested areas in the Valley receiving parasite introductions followed the same pattern. The natural enemy complex consists of 3 imported parasites, Pseudaphycus malinus Gahan, Allotropa burrelli Muesebeck, A. convexifrons Muesebeck, and Zarhopalus corvinus (Girault), an indigenous parasite of P. maritimus (Ehrhorn), plus native predators, mainly Leucopis ocellaris Malloch and Chrysopa spp. A. convexifrons , the last to be established, is now the dominant parasite. The population density of P. comstocki was reduced by a maximum of 68% in East Porterville from 1972 through 1976, 71% in Central Porterville, and 73% in West Porterville from 1974 through 1976 as a result of the newly established natural enemy complex.

Of eight test woods, yellow-poplar sapwood was preferred for egg-laying and was best for larval survival and growth. Slash pine was also favorable for egg-laying, survival, and growth. Beetles laid more eggs on Douglas-fir plywood and sweetgum than on shortleaf pine, but larvae did not survive in the plywood, and tunneled extensively without appreciable growth in sweetgum; larvae survived and grew well in shortleaf pine. The beetle life cycle is at least 2 years in favorable woods and may be 3-5 years in unfavorable woods. JF - Canadian Entomologist AU - Williams, L H AU - Mauldin, J K AD - Southern Forest Exp.

Quantitative measurement of soil humus, decayed wood, and charcoal as related to numbers of active ectomycorrhizal root tips (in random soil cores from old-growth sites in western Montana) showed both positive and negative relationships with organic matter. Increased quantites of organic material, to 45 percent by volume of the top 30 cm of soil, were associated with increased numbers of ectomycorrhizae. At 45 percent organic matter or above, numbers of ectomycorrhizae decreased. Study results also showed association with soil organic matter had a relatively greater positive effect on ectomycorrhizae of the dry site than the moist sites.

AN - 15358629; 188008 AB - The Chinese mantid, Tenodera aridifolia sinensis Saussure, is one of the largest of mantids (73-103 mm) and probably powerful enough to subdue and feed upon small vertebrates. The only published account of this species feeding on a captured vertebrate, however, describes the feeding on a captured Trionyx soft-shelled turtle. Though demonstrating the mantid's ability to subdue heavy vertebrates, this observation was unnatural in that both the turtle and mantid were enclosed in a small terrarium-aquarium. The capture and feeding by the Chinese mantid on a mouse is documented here. The description is substantiated with Polaroid) color photographs now on file in the Systematic Entomology Laboratory, USDA, National Museum of Natural History, and which are unfortunately not of reproducible quality for publication.

Starch granules were successively washed with 0.02 M Na-phosphate buffer containing 0.9% NaCl. The alkaline hydrolysate of washed materials and acid hydrolysate of protein-bound amylopectin were separated by use of Con A-Sepharose. Amylolytic hydrolysate of starch granules also was carried out with alpha -amylase and fractionated by chromatography on Sephadex G-25. Amylopectin was the only glucan glycosidically linked with proteins, in which glucan synthetase activity was identified. The amylose component was free from covalently bound proteins.

The biologies of these weevils were similar; teneral adults appeared in the spring and fed for 2 to 3 weeks on leaves of the primary host, Carduus macrocephalus Desfontaines, before estivation in the soil. Both weevils resumed feeding in the fall. Mating and oviposition occurred from November to March. Eggs of C. trimaculatus were laid on the surface and under the epidermis of the leaves, whereas eggs of T. horridus were laid in feeding grooves in the midrib. Larvae of both species fed together in the crowns and buds from December to April, but no cannibalism was observed. More larvae of T. horridus fed in buds than did larvae of C. trimaculatus . Pupation occurred in the soil. Both weevils were univoltine. JF - Environmental Entomology AU - Boldt, P E AU - Campobasso, G AD - AR, SEA, USDA, Grassland Soil and Water Res. Lab., P.O.

AN - 15355019; 171145 AB - Two cationic carboxypeptidase fractions (CMS-G-1 and CMS-G-2) were isolated from the midgut homogenate of larvae of the black carpet beetle, A. megatoma, through a series of ion exchange and affinity gel chromatographic steps. Fraction CMS-G-2 was highly active against the substrates hippuryl-DL- beta -phenyllactate, N-carbobenzoxy-glycyl-L-phenylalanine, and N-carbobenzoxy-glycyl-L-tyrosine and was thus similar in specificity to bovine carboxypeptidase A. Fraction CMS-G-1 was most active against N-carbobenzoxy-L-valyl-L-leucine and N-carbobenzoxy-glycyl-L-methionine. Fraction CMS-G-1 also hydrolysed (in decreasing order) blocked peptides with carboxyl terminal L-isoleucine, L-leucine, L-alanine, and L-valine but was only slightly active against the ester and peptide substrates of carboxypeptidase A. Neither CMS-G-1 nor CMS-G-2 hydrolysed N-carbobenzoxy-glycyl-L-proline or glycyl-glycine. Between CMS-G-1 and CMS-G-2, at least four bands with peptidase activity were resolved on a cationic polyacrylamide gel system. JF - INSECT BIOCHEM.

AN - 15352237; 181761 AB - As irrigation water becomes more limited and energy costs increase on the Southern Great Plains, more cotton (Gossypium hirsutum L.) acreage will be diverted to dryland production. Because water is the most limiting resource for cotton production in this region, production will be positively related to changes which increase the water supply or make more efficient use of water. The purpose of this study was to evaluate plant (shoot) dry matter accumulation in photoperiodic (exotic) cotton stains under irrigated (water optimal) and dryland (water stressed) field conditions, to estimate their water-use efficiency under dryland, and to determine the relationship between field growth parameters, laboratory evaluations of heat tolerance, and greenhouse estimates of root growth.

AN - 15349313; 165978 AB - Pepper (Capsicum annuum ), soybean (Glycine max ), and tomato (Lycopersicon lycopersicum ) plants were exposed to saline aerosols until incremental salt deposition levels of 0.2, 0.4, 0.6, and 0.8 mg Cl super(-) cm super(-2) of horizontal surface area were achieved. Foliar necrosis became evident on the 0.4 mg Cl super(-) cm super(-2) treatments after 3, 7, and 8 days on tomatoes, soybeans, and peppers, respectively. Severity of injury increased with increasing salt deposition and time. Foliar absorption of Na super(+) Cl super(-) was linearly related to the amount of salt deposition on leaves. No injury symptoms were apparent on any species at any salt deposition level when relative humidity (RH) was maintained at approximately 70% during the same period. Similar results were obtained where treated tomato, soybean, and pepper plants were compared at treatments of 70 and 100% RH during predawn hours but without dew formation. The injury at 100% RH, however, was not as pronounced as when plants were exposed to dew.

AN - 15349180; 165860 AB - Corn (Zea mays L.) management systems involving two nitrogen (N) fertilization methods and two supplemental irrigation levels were evaluated for soil water percolation and N leaching losses in west central Minnesota. Annual soil water percolation from spring thaw to fall freezeup averaged about 7.1, 11.2, and 18.0 cm for nonirrigated corn, 2.5-cm irrigated corn, and 5-cm irrigated corn, respectively. Average annual NO sub(3-)N leaching losses ranged from about 29 to 112 kg ha super(-1), and the combination of variable rainfall, soil NO sub(3-)N content, and low soil water-holding capacity caused great variation within and among years. Compared with values for fertilized nonirrigated corn, annual NO sub(3-)N leaching losses increased an average of 17 and 53%, respectively, for the partial and full replenishment irrigations.

Nitrosamines were detected and quantitated by a gas liquid chromatograph interfaced with a Thermal energy Analyzer. Detectable N-nitrosodimethylamine, the only nitrosamine found, ranged from .05 ppb for whole milk to .30 ppb for nonfat dry milk. No N-nitrosodimethylamine was detected in raw milk, whereas 11 of 21 samples of pasteurized milk contained apparent N-nitrosodimethylamine at a mean .10 ppb. N-nitrosodimethylamine also was detected, but not confirmed by mass spectrometry, in evaporated and condensed milk with means .32 ppb and .58 ppb and in 9 of 10 nonfat dry milk samples with a mean of 1.69 ppb.

AN - 15347965; 162757 AB - Dendrosoter protuberans (Nees) was introduced into the United States from France as a possible addition to the existing spectrum of hymenopterous parasites of the smaller European elm bark beetle, Scolytus multistriatus (Marsham). D. protuberans is an external parasite; it oviposits through bark onto or next to late-instar larvae of S. multistriatus . The biology of Entedon leucogramma Ratzeburg has been described by Beaver (1966). E. leucogramma is an endoparasite of S. multistriatus . The female of E. leucogramma enters the egg gallery as it is being developed by the female bark beetle and oviposits in newly deposited bark beetle eggs. The female wasp advances into and retreats from the bark beetle egg gallery as the female bark beetle works in and out of the gallery. The larva of E. leucogramma develops internally in the larva of S. multistriatus as the latter matures. As the larva of S. multistriatus matures to a late instar, the parasite larva completes development, emerges from the remains of the bark beetle larva, and pupates. The purpose of this paper was to find out if D. protuberans oviposits on late-stage larvae of S. multistriatus already parasitized internally with a larva of E. leucogramma .

Individually or together as a complex, these viruses cause considerable reduction in both yield and ear quality. Both viruses overwinter in infected Johnsongrass and in the spring are transmitted to corn by aphid and leafhopper vectors. The most practical control for these diseases is to plant hybrids with virus resistance, good ear quality, and high yielding capacity.

AN - 15345400; 166089 AB - The southern pine coneworm, Dioryctria amatella (Hulst), (Lepidoptera: Pyralidae) is nocturnal and reproductive behavior occurs only during the last 5 h of scotophase (12L:12D photoperiod). Mating does not begin until moths are 2 days old and mating and oviposition are dependent on the presence of the host plant. Statisfactory rearing required surface sterilization of eggs with sodium hypochlorite, autoclaving the dietary wheat germ, inclusion of no more than 2 per 30 ml container. The described methods have been used to rear more than 40 successive generations of the insect on the WGCS medium. JF - Florida Entomologist AU - Fatzinger, C W AD - USDA, For.

Significantly higher levels of physical activity were measured for mites exposed to human breath and to the CO sub(2)-dry air mixture than were measured for the other gas mixtures. This result indicated that CO sub(2) emission by potential hosts may be a factor contributing to the host-seeking abilities and, thus, the dispersal of the mites throughout a flock.

Up to 6 percent of the basal area of red (Quercus rubra L.) black (Q. velutina Lam.), scarlet (Q. coccinea Muenchh.), and white (Q. alba L.) oak was sacrificed per stand. Borer populations were reduced by about 50 percent in the first generation after treatment and by about 90 percent in the second generation.

AN - 15340463; 165841 AB - Aside from economic considerations, potential solutions for dryland salinity problems must be related to the specific site conditions. They may include interception drainage, drainage of water from perched water tables, reduction of hydrostatic pressure in artesian systems, as well as soil and crop management systems. The viability of these (or other) solutions can only be assessed after adequate delineation of the site conditions, including identification of the recharge area, description of the subsurface conditions with evaluation of the hydraulic properties of the aquifer materials traversed by the flux, and sufficient information to derive the flow paths. In addition, the time dependence of the flow system must be considered. Whereas flow problems have most often been solved in terms of potential distributions, it will be helpful to pay more explicit attention to velocity fields and transit times.

Fresh cattle feces containing the equivalent of 224 kg N/ha were applied to duplicate plots of Coastal bermudagrass for determinations of pasture yield: 1) when feces are buried by dung bettles, and 2) when feces remain on the pasture surface. The results indicated that increasing the dung beetle population on pastures by introduction of foreign species of beetles would be very beneficial for forage production in high density grazing systems.

Management practices that increased recharge most were increased depth of flooding and partial incorporation of an organic mat (cotton gin trash) in the bottom of recharge basins. Addition of cationic flocculent to playa water increased the total amount of playa water infiltrated when suspended sediment content of the water was 250 to 300 mg/L but had little effect on infiltration when water contained 150 mg/L suspended solids.

AN - 15337076; 161947 AB - Sodium hypochlorite and sodium dichlorisocyanurate were tested against Salmonella typbimurium . The test organism was killed rapidly by the sanitizers in water. When 1.0% egg solids was added, antimicrobial activity rapidly decreased and was slight after 1 hr. The commercial chlorinated cleaner gave a pH of 11.2, and Streptococcus faecalis was used as the test organism since salmonellae do not survive at this pH. This cleaner at 240 ppm active chlorine was effective in water but was ineffective against the test organism after incubation 30 min with 1% egg solids despite the presence of 52 ppm residual active chlorine by the chemical test. Tests in a commercial plant demonstrated that active chlorine chemicals added to wash water were completely inactivated in a few minutes. An iodophor was tested. At 25 ppm I sub(2), the iodophor was ineffective when egg solids were added. At 949 ppm I sub(2) and pH 3.52 the iodophor rapidly killed the salmonellae even after incubation for 1 hr with 2 % egg solids and 710 ppm I sub(2) remained.

AN - 15335950; 136605 AB - Foraging Red-cockaded Woodpeckers (Picoides borealis ) selected live pines (96% use; 71% availability) over hardwoods (1% use; 25% availability). Use of recently dead pines (3%) was the largest departure from use of live pines. Live pine stems greater than 23 cm in diameter at breast height represented only 19% of the available pines but received 65% of the use. The sexes exhibited strong divergence in foraging behavior. Most important was the partitioning of foraging sites on live pines. Males foraged on dead and live limbs of the crown and midtrunk 54% of the time and females only 4%. On the lower trunk, females foraged 38% of the time and males only 3%. On the midtrunk, females foraged 29% and males 12%. On the trunk-in-crown, females foraged 28% and males 32%. Mean foraging height of males was 14.1 m and that of females 8.7 m (P < 0.001). Within each sex, there were between-season differences in use of foraging sites and in methods used at each site.

Collections of insects were made at 391 sites in 19 study areas in Texas, New Mexico, Arizona, and Mexico. The reaction of deomestic animals to the pellets was recorded, and pellet-baited small mammal traps were set in selected areas. Diptera comprised 93.5% of the insects collected, and 88.5% of these were Calliphoridae, Sarcophagidae, Anthomyiidae, and Muscidae. Mammals caught in traps included Neotoma micropus Baird, N. albigula (Hartley), Spermophilus mexicanus (Erxleben), and Sylvilagus floridanus (Allen). Domestic animals have little or no interest in the pellet as food. On the average, ca. 10% of all pellets were degraded or removed from a site within one wk.

Engorged nymphs had higher molting success (76%) at lower humidities (35% RH, 20 degree C) than engorged larvae (14%), which indicated a greater survival potential under desiccating conditions. Optimum conditions for molting were 85 and 95% RH at 27 degree C for engorged larvae (96-97% molted) and engorged nymphs (97-99% molted). High temperatures (35% degree C) and low humidities (35% RH) prevented molting of all engorged larvae and nearly all nymphs. Unfed numphs were stressed at humidities below 85% RH at any temperature but they were especially vulnerable at high temperatures.

AN - 15332813; 135783 AB - In central Appalachian hardwood stands songbirds were classified into groups of species that selected territories with similar habitat features. The degree of canopy closure of trees > 7.3 m tall and the density of vegetation < 1.8 m tall were the most important habitat features. Discriminant analysis was used to separate bird species into 5 groups based on habitat selection: (1) closed-canopy-obligatory species included Seiurus aurocapillus, Sitta carolinensis, Hylocichla mustelina , and Setophaga ruticilla ; (2) species skewed toward closed canopy were Mniotilta varia, Parus carolinensis, Cardinalis cardinalis, Wilsonia citrina, Vireo olivaceus, Piranga olivacea, Parus bicolor , and Polioptila caerulea ; (3) centrally distributed species included Contopus virens and Myiarchus crinitus ; (4) species skewed toward open eanopy were Thyothorus ludovicianus, Pipilo erythrophthalmus , and Passerina cyanea ; and (5) obligatory open-canopy species included Icteria virens, Spizella pusilla, Dendroica discolor , and Sialia sialis Changes in groups can be predicted by the change in configuration of overstory and understory vegetation. Bird succession following cutting generally follows sequentially from open-canopy-obligatory to closed canopy-obligatory species; however, the initial stage depends upon the degree to which the stand was opened.

These paralyzed hosts provided female parasites with a readily available food source which increases parasite longevity and fecundity and an alternate oviposition site, allowing parasite numbers to increase in advance of the pest population.

AN - 15332508; 164404 AB - The nesting biology (nest consruction, cocoon, sex ratio) of a desert bee, O. marginata michener, is described. The bee nests were obtained from trap stems placed at Mojave and Sonoran Desert locations in southern California, Nevada, Utah, and Arizona. O. marginata visited legume flowers for pollen but smaller amounts of Composite, primrose, and convolvula pollens were also used. Ten species of arthropod parasites and predators were associated with the bees' nests; the most common parasites were the wasps Chrysura colbaltina (Aaron) and Leucospis affinis Say and the bee, Stelis depressa Timberlake.

AN - 15331688; 160693 AB - Mixed cultures of rumen bacteria were inoculated into anaerobic buffer solutions containing mixed carbohydrates, casein and ammonia, and rates of bacterial growth, protein degradation, ammonia formation or utilization and lactate production were determined. Lactate production and protein degradation were negligible during the initial phases of the high carbohydrate, fast growth rate incubations, but large increases in each were seen after 3 hours. Microscopic examination of the fast growth incubations revealed large numbers of small ovoid cells similar to S. bovis , while the slow growth incubations exhibited a variety of morophological types and very few small ovoid cells. The lactic acid and morphological data suggested that proliferation of S. bovis might be responsible for rapid proteolysis. Actively proteolytic strains of S. bovis were isolated from fast growth incubations, and subsequent experiments showed that the ratio of protein degraded to bacterial protein synthesized was approximately 1.50. Collectively, the data indicate that S. bovis is a very proteolytic rumen bacterium. JF - Journal of Animal Science AU - Russell, J B AU - Bottje, W G AU - Cotta, MA AD - AR-SEA-USDA, Dept. Anim.

AN - 15328717; 155428 AB - A rapid, precise and accurate microtiter most-probable-number (MPN) procedure has been developed and tested for simultaneous (two reagent addition) enumeration of denitrifier and nitrate reducer populations in an agricultural soil. Values from 0.12 x 10 super(6) to 0.22 x 10 super(6) denitrifiers g super(-1) soil were determined using two concentrations of each terminal electron acceptor in nutrient broth. Nitrate reducer populations ranged from 0.97 x 10 super(6) to 1.1 x 10 super(6) organisms g super(-1) soil when two concentration NO super(-) sub(3) were employed. The denitrifiers thus constituted 12-20% of the nitrate reducer population. Neither method (tube or microtiter) or medium significantly altered the values obtained for these two groups of microorganisms.

AN - 15325832; 135616 AB - R. japonicum strains possessing the hydrogenase characteristic (Hup super(+)) are capable of forming nodules that recycle the H sub(2) produced during N sub(2) fixation. Experiments were conducted to compare seed yield and N content of soybean inoculated with Hup super(+) and Hyp super(-) strains under field conditions. Hup super(+) wild-type strains, H sub(2) uptake negative (Hup super(-)) wild-type strains and Hup super(-) mutants were used as inoculants. Chelis silt loam and Ephrata loamy fine and relatively free of indigenous R. japonicum) were used in the experiments. The inoculants applied to these relatively high N soils did not significantly affect seed yield, however, plants inoculated with the Hup super(+) strains appeared greener, matured later, and in all four experiments produced seed with significantly higher N percentage than plants inoculated with groups of Hup super(-) strains. Average data from all four experiments showed that Hup super(+) inoculants increased crude seed protein 8.9%. These results provide further evidence that R. japonicum) inoculants for soybeans should possess the capacity to oxidize H sub(2) produced as a by-product of N sub(2) fixation. JF - AGROM. J.

AN - 15325492; 142189 AB - Four D-glucanases in the crude culture-both of Oerskovia xantimeolytica act synergistically to degrade the walls of viable yeast. Enzyme I has a molecular weight of similar to 18,000, but does not lyse viable yeast cells, even though it displays high activity against laminaran, and will readily depolymerize lichenan. It is an endo-glucanase (E.C.3.2.1.6). Enzyme II is also an endo-glucanase (E.C.3.2.1.29) having a molecular weight of similar to 29,000 and is active against both viable yeast cells and laminaran, but it exhibits restricted activity against lichenan. Enzymes IIIa and IIIb have molecular weights of 27,000 and 29,000, respectively, and exhibit high lytic activity against viable yeast cells, but release few reducing groups from laminaran or yeast glucan. In the initial stages of hydrolysis, they act in an endo-manner, but they effect cleavage of a d.p. 14 substrate in an apparent exo-manner. They have high specificity for straight-chain, beta -(1 arrow right 3)-linked D-glucan. The proposed systematic name for enzymes IIIa and IIIb is (1 arrow right 3)- beta -D-glucan pentaosehydrolase.

These data clearly indicated that under laboratory conditions the susceptibility of a given instar is affected by the stage of development of the mosquito population in which it is exposed. This may also be the case in nature and could be a major factor in the reduced levels of infection encountered in first-instar larvae in previously mentioned studies.

AN - 15322183; 129175 AB - One of the invertases ( beta -D-fructofuranoside fructohydrolase, EC 3.2.1.26) isolated from Avena seedlings was very sensitive to mercuric ion, with 60% inhibition by 0.4 mu M HgCl sub(2), but concentrations of HgCl sub(2) as high as 2mM did not increase the inhibition. The enzyme and mercuric ion formed a complex that was stable to dialysis and gel filtration and to the addition of cyanide and EDTA. Cysteine had no effect on the activity of the invertase, but when added to the mercuric ion-invertase, it increased the inhibition of 93%. Other thiols and cysteine derivatives exerted effects ranging from augmentation to reversal of the inhibition. Of all the reagents tested, cysteine and N-acetyl cysteine were the most effective in increasing the inhibition. However, the effectivness of cysteine was destroyed by removal of either the amino group or the carboxyl group and by increasing the carbon chain by one unit (homocysteine).

AN - 15321957; 141199 AB - In laboratory tests conducted to determine the effectiveness of the exotoxin of Bacillus thuringiensis against the Colorado potato beetle, Leptinotarsa decemlineata (Say), applications sprayed on tomato foliage at dilutions ranging from 10 super(-1) through 10 super(-4) killed 90% of the 1st and 2nd stage beetle larvae. As the dosage decreased, the time to achieve this level of mortality increased from 4 to 9 days. Adult beetles were not killed by these treatments; however they did cease feeding. In field tests, the highest dosages of B. thuringiensis , sprayed on either tomato or potato plants provided adequate or nearly complete protection when applied weekly. Young larvae that ingested sub-lethal doses developed into adults with atropied mouthparts and antennae, transformations of the paired parts of the labial palps into an unpaired part, the appearance of a tarsal-like claw on a palp, and malformation of the cranial sclerities.

AN - 15320374; 144624 AB - The interpretation of the probabilities presented in this paper is that none of the competing biological risks, acting in the presence of other risks, offers much, if any, regulatory influence upon a mountain pine beetle population. Consequently, if no single risk, or combination of these risks, offers much help, then the contention that mountain pine beetle Dendroctonus ponderosae populations are food-regulated is once again strengthened. The evidence remains (or continues) that the mountain pine beetle is food-regulated at optimum temperature conditions and temperature-regulated at optimum food conditions. Reducing and/or minimizing tree loss to the mountain pine beetle is thus dependent upon manipulating the food supply or management of the tree (stand) growth.

The major toxicity of culture extract of the fungus was due to the presence of several trichothecene mycotoxins. Six trichothecenes were isolated and chemically identified by spectroscopic methods as T-2 toxin, HT-2 toxin, T-2 tetraol, 3 alpha , 4 beta , dihydroxy-15-acetoxy-8 alpha -(3-hydroxy-3-methylbutyryloxy)-12, 13-epoxytrichothec-9-ene, 3 alpha , 4 beta , 15-trihydrozy-8 alpha -(3-hydroxy-3-methylbutyryloxy)-12, 13-epoxytrichothec-9-ene, and 3 alpha , 4 beta , 8 alpha -trihydroxy-15-acetoxy-12, 13-epoxytrichothec-9-ene. The acute toxicities of the trichothecenes were compared to the effects of T-2 toxin in day-old chickens and on the back skins of rabbits. The comparative inhibitory effects of the trichothecene mycotoxins in the Triticum coleoptile bioassays were also determined. JF - J. NAT. PROD. (LLOYDIA).

AN - 15298371; 124581 AB - A recently discovered, widely distributed canker disease of aspen and other poplars throughout the Rocky Mountain region is described. Inoculations with ascospore and conidial isolates of Cryptosphaeria populina show the fungus is capable of causing branch, sprout, and sapling mortality, trunk cankers, and the discoloration and decay of aspen stems previously associated with its imperfect stage, Libertella sp. The greatest average canker elongation 50 mo after September inoculations was 33.5 cm with sapwood decay and discoloration extending to 401 cm. The fungus caused an average weight loss of 13.5% in bark, 27.0% in sapwood, and 19.1% in heartwood blocks. Incidence of decay in living trees in Colorado was 7.8%, increasing from the poorer sites to the better sites, and increasing with diameter class. Sapwood discoloration around and beyond the infection perimeter exhibits a yellowish fluorescence under ultraviolet light as does a water filtrate of the fungus grown in culture. Sapwood discoloration may be the result of materials produced by fungal pathogens rather than by the host response. JF - Phytopathology AU - Hinds, TE AD - USDA, For. Serv., Rocky Mountain For.

AN - 15298294; 127820 AB - Red pine (Pinus resinosa ) trees growing in Wisconsin were treated with paraquat to induce synthesis and deposition of high oleoresin contents (lightwood production), or with water (controls). The trees were harvested 2 yr later and wood chip samples containing average levels of nonvolatile oleoresins of 3.9 (controls), 9.7, and 15.9% were obtained. These samples were subjected to decay by the typical wood decay fungi, Phanerochaete chrysosporium, Poria subvermispora, Gloeophyllum trabeum , an unknown basidiomycete (ME-493), and by the soft-rot fungus, Papulospora sp. Weight losses caused by each of the test fungi were consistently less in the lightwood than in the normal wood chips.

AN - 15297969; 124160 AB - Cereal leaf beetle, Oulema melanopus (L.), prepupae, pupae, and adults in pupal cases were subjected to regimes of 4 temperatures and 5 relative humidities to determine mortality at each developmental stage. Temperatures ranged from 26.7 to 35.0 degree C and relative humidities from 13 to 71%. Mortality was greatest at the higher temperatures and lower relative humidities. These findings suggest that high soil temperatures with low soil moisture might limit cereal leaf beetle survival in the warm, dry Great Plains states.

AN - 15297895; 117454 AB - An inoculation technique was developed to test seedling plants of winged beans (Psophocarpus tetragonolobus (L.) DC.) for resistance to false rust disease incited by the fungus Synchytrium psophocaropi (Rac.) Gaumann. Sporangia were collected in distilled water by washing or scraping from infected, sporulating winged bean leaves. Inoculum was applied by brushing the sporangial suspension onto the 1st or 2nd true leaves of seedling plants, and holding the inoculated plants under high humidity conditions for 24 hours. Intensity of infection can be scored 10 days after inoculation. Resistance appears to result from a hypersensitive reaction. JF - HortScience AU - Parman AU - Thompson, A E AD - USDA-SEA-AR Nat.

Wild bees as a group and some oligolectic females were more effective in pollinating florets than were the apids (honey bees and bumble bees). In comparisons of the fidelity of bee visitation to either sterile or pollen varieties, apids preferred male sterile rows, some wild bee species were evenly distributed between sterile and pollen rows, and other wild bees preferred pollen rows. In comparisons of the amount of pollen carried on a bee body, oligolectic sunflower bees carried more pollen than did other kinds of bees.

AN - 15295058; 122409 AB - The inheritance of resistance of rust in sugarcane was studied in 13 F sub(1) and two S sub(1) families involving eight clones as parents. Results indicated marked transgressive segregation toward susceptibility in all F sub(1) and S sub(1) families studied. The skewed distribution of rust rating toward susceptibility in most of those families suggests that resistance to rust was partially dominant. Analysis of variance showed that the maternal component was much greater than the paternal component and a large amount of variance was due to nonadditive genetic effect and common environment. Susceptible parents tended to transmit a higher frequency of rust-susceptible genes to their offspring.

AN - 15291924; 120490 AB - Sample sets were collected from four egg-grading plants. Each set included bacterial counts in washwaters, brushes, egg conveyors, and washed and unwashed eggs. Bacterial counts on eggs, in washwater, and on equipment surfaces were unaffected when a water rinse was used in place of a chlorinated rinse following washing. Use of a chlorinated wasing compound significantly lowered bacterial counts on conveyors but not in other samples. Thoroughly rinsing equipment at the end of each day's operations markedly reduced bacterial loads on equipment surfaces and in washwaters. Bacterial counts on washed eggs were significantly correlated with counts on equipment surfaces, in washwaters, and on unwashed eggs. Counts in washwaters were correlated with those on equipment surfaces but not with counts on unwashed eggs. The major source of bacteria in washwater was evidently the equipment rather than the eggs. Careful daily cleaning of equipment should maintain low bacteria counts on equipment surfaces and in washwater and consequently reduced bacterial contamination of washed eggs.

AN - 15289204; 116018 AB - Regeneration of balsam poplar (Populus balsamifera ) was studied following clearcut logging with both chain saws and tractor-mounted shears in summer and winter. Logging with shears in both summer and fall resulted in the most surface disturbance and the greatest rate of poplar regeneration. Regeneration was from seeds, stump sprouts, root suckers, and buried branches. Regeneration in summer and winter-logged sites was primarily from root suckers, but logging in the fall resulted in regeneration from buried branches. Revegetation of clearcut areas was rapid and dominated by grasses, horsetails, willows, alders; and devil's club. Production of moose browse was much greater in the logged areas than in an unlogged control. Limiting clearcutting to summer and encouraging disturbance of the surface could increase poplar regeneration.

They were identified as a new genus of Mermithidae , the first to be reported from North America. From 38 to 74% of boll weevils captured in pheromone traps in winter and spring in 1974 were infested by the mermithid nematode. However, only 8-15% of the boll weevils collected from surface woods trash were infested. The data suggest that the adult weevil is parasitized by the nematode in the hibernation site. JF - J. GA.

AN - 15286927; 118869 AB - The interrelationship between 4 species of ants and the sugarcane borer, Diatrea saccharalis F., was studied over a 6-month period in Florida. Ants were collected monthly from May to October, and numbers were compared with those of sugarcane borers collected bi-weekly during the same period. The data showed a slight increase in sugarcane borer damage in the fields treated with mirex (dodecaclorooctahydro-1, 3,4-metheno-1 H-cyclobuta(cd)pentalene) to reduce populations of the red imported fire ant, Solenopsis invicta Buren. Pearson's correlation cofficients were positive between the sugarcane borer and the red imported fire ant but negative between the sugarcane borer and Pheidole dentata Mayr and P. floridana Emery. These data suggest that the reduction of all ant species with mirex bait resulted in increased damage from the sugarcane borer and that a multiple predator ant complex is more effective than one dominated by S. invicta .

AN - 15286700; 118020 AB - Properties of an aminopeptidase isolated from midguts of larvae of the black carpet beetle, Attagenus megatoma , by anionic and cationic ion exchange and affinity chromatography were studied by use of the substrate L-leucine-p-nitroanilide. Inhibition of the enzyme by metal chelators and the results of dialysis experiments indicated that the aminopeptidase was a metalloprotein. The concentration of alcohol required for complete inhibition of the enzyme was inversely related to alcohol chain length. The aminopeptidase cleaved L-amino acids from the N-terminal end of dipeptides and tripeptides and also hydrolyzed a number of aminoacyl- beta -naphthylamides.

Although quarantines have been established to prevent its rapid spread, the disease is present also in Maine and in the Canadian provinces of New Brunswick, Quebec, and Newfoundland. To determine the potential for widespread damage, most U.S. native conifers were field-tested for susceptibility. All pines tested proved highly susceptible, and other conifers were susceptible to varying degrees. The best opportunity for control lies in developing genetically resistant conifers.

Flies are marked with fluorescent powders and recaptured on fiberglass panels treated with adhesive. The theoretical model used for estimating population sizes from recapture data includes adjustment for the mortality and emigration of marked flies and allows for continuous trapping of flies during time periods of unequal length. Results of field tests indicated that general trends in wild populations are adequately measured with the system, but weather changes may affect the trapping efficiency of the fiberglass panels.

AN - 15284096; 115338 AB - The detection efficiency of grandlure-baited infield traps was evaluated for the F sub(1) progeny of one overwintered female boll weevil, Anthonomus grandis) Boheman, (Coleoptera: Curculionidae), from a "clumped" emergence pattern. The probability of detecting at least one of the F sub(1) progeny of one female was calculated with a simple model to be 63.2 and 99.1%, respectively, for 2.5 and 10 traps/ha. The capture rate with 10 traps/ha over a period of 21 days was essentially equal to the expected capture rate of 83.6% of the females when uniform distribution of both traps and boll weevils and equal attraction of mate-seeking females to traps and to males was assumed. These favorable results were attributed to the ability of the synthetic pheromone released by the traps to largely overpower the attractiveness of the males despite the closer proximity of the males to mate-seeking females.

AN - 15283142; 116246 AB - Soil in microplots was infested with three vesicular-arbuscular (VA) symbionts then sown with seed of half-sib progeny from nine sweetgum mother trees. The VA treatments were Glomus fasciculatus, Glomus spp. or a VA mixture of several fungi from the genera Glomus and Gigaspora . Mycorrhizal seedlings with G. fasciculatus were slightly but not significantly larger in both height and root-collar diameter than were seedlings with the Glomus spp. or the VA mixture. Progeny from four of the mother trees were consistently larger than those from the other five but progeny from three of these five were consistently smaller regardless of the VA mycorrhizal treatment. Significant differences in percentage of roots infected and in intensity of infection within root segments were found among the three treatments, but these differences were not correlated with seedling growth. There were some differences in mineral analyses of tissue from seedlings among the different mycorrhizal treatments and the control but no consistent trends were observed in any of the parameters in the tests.

AN - 15281030; 116208 AB - Construction and use of trails and campsites, grazing by recreational packstock, and suppression of fires have altered the vegetation of the Eagle Cap Wilderness Area in northeastern Oregon, USA. The amount and type of alteration has varied among vegatation types and with the kind of activity. Changes attributed to intensive recreational use are localized but severe, particularly in more densely forested areas. Suppression of fires has produced subtle but widespread changes. Current attempts to minimize these changes are often inadequate due to the lack of ecological information and the difficulties of implementing regulations. Management suggestions are offered.

AN - 15279938; 116590 AB - Simulated rainfall (6 cm/hour) was used to leach P from growing cotton 9(Gossypium hirsutum ), sorghum (Sorhum sudanese ), and soybean (Glucine max ), plants as a function of soil type and time interval between rainfall events. The relative contribution of plant material and surface soil to the transport of soluble P in surface runoff was estimated. The amount of soluble P in plant leachate, was found to increase with plant age and soil-water stress when changes in leaf area index were accounted for. A period of at least 1 day between rainfall events was needed for P to reaccumulate on the leaf surface. When plants were subject to a soil P stress, canopy leachate contributed of plant leachate to surface runoff increased. The possible sorption of leached P is discussed along with estimating leaching losses in improving the predictive ability of nutrient models.

AN - 15279798; 114019 AB - A wind erosion equation, which estimates annual potential erosion, requires that all vegetative cover be expressed as a small grain equivalent. Wind-tunnel tests were used to determine that equivalent for seven crops: cotton, forage sorghum, rape, silage corn, soybeans, sunflowers, and winter wheat-five at two orientations (standing and flat-random). Among the crops and orientations tested. Standing winter wheat residue was the most effective for wind erosion protection and flat-random sunflowers the least effective. Multiple regression equations were determined, or where available, used, for extending the results to any other crop characterized by amount and stalk diameter, height, and specific weight.The small grain equivalants data along with other factors in the wind erosion equation, may be used to predict potential wind erosion at specific crop sites or to determine residue amounts needed to hold potential wind erosion to tolerable limits.

AN - 15279548; 116605 AB - From mid-May to mid-September 1978, nitrous oxide (N sub(2)O) emissions from an irrigated corn (Zea mays) L.) field in northern colorado totaled only 2.5 kg N ha super(-1), and even smaller losses were measured from a nearby sugarbeet (Beta vulgaris L.) field. Fluxes compared favorably with micrometeorological estimates of vertical N sub(2)O flux density. About 30% of the N sub(2)O lost from the corn field was emitted during the 2 weeks following fertilization, and 59% was evolved during the week following the field's first irrigation. Other occurrences of irrigation or precipitation exceeding 0.7 cm were also followed by rapid, increases in N sub(2)O emissions. The flux of N sub(2)O was not significantly correlated with soil nitrate concentration but was strongly correlated with soil water content and N sub(2)O concentration in the soil atmosphere. No evidence was found that either site ever behaved as a sink for tropospheric N sub(2)O. JF - Journal of Environmental Quality AU - Mosier, A R AU - Hutchinson, G L AD - USDA-SEA-AR, P.O. Box E, Ft.

The new stand, after 35 years, is dominated by fast growing, shade-intolerant black cherry (Prunus serotina Ehrh.) in the overstory whereas the slower growing sugar maple (Acer saccharum Marsh.) and beech (Fagus grandifolia Ehrh.) are relegated to the understory. Where the tolerant species were retained as saplings up to 5 or 6 inches d.b.h. after cutting they are represented in the larger diameters and upper crown strata.

The calling behavior lasted from a few seconds to several minutes and was repeated periodically throughout the dark period. A hexane extract of abdominal tips excised from calling females was attractive to laboratory-reared males in bioassays conducted in small screenwire cages in the greenhouse and to native males in field trapping trials. Laboratory-reared and native females were ca. equally attractive to native males in the field. The selective laboratory rearing regimen has not unduly influenced the quantity or quality of the BAW pheromone produced by the laboratory strain. JF - J. ENVIRON. SCI.

We used continuously mixed anaerobic fermentors with 3-liter working volumes at 35 and 55 degree C; these fermentors were fed once per day. Within a few days after waste from animals fed monensin was added, the volume of methane produced began to decrease in the 55 degree C fermentors. In a batch fermentation experiment in which 50-g portions of volatile solids from waste of animals fed monensin, chlortetracycline, or no antibiotics were added to fermentors, monensin delayed the onset of methane production for about 40 days.

Experimental procedures are detailed. Plant tissue Mn levels increased with the application of Cd, Cu, Ni, and Zn (in combination) as metal salts or as sewage sludge over the range of soil materials used. The amount of increase with a given increase in applied metals was greater for the unlimed than for the limed metal salt treatments. Elevated tissue Mn concentrations were positively and significantly correlated with indigenous levels of soil Mn.

The kinematic wave equations for turbulent flow across a plane impermeable surface are solved using a time-varying rainfall appropriate for thunderstorms. Peak discharge is shown to be a function of surface length, total precipitation , storm duration and the time to equilibrium for an equivalent rainfall of constant intensity. A correct value of the time to equilibrium is difficult to estimate but is essential for estimation of peak discharge. The constant intensity approximation is valid for rainfall durations approximately equal to the time to equilibrium or less. As the relative duration increases, the approximation becomes less valid.

Summary data on the chemical analyses made of precipitation and streamflow samples are given and their interpretation discussed, noting the net losses and accumulation for total nitrogen, phosphorus, sodium, magnesium, calcium and silica. The underlying parent material and bedrock weathering are considered to be the major influence on streamflow chemistry, with the abundant organic soils of the region defining the organic outputs; chloride, calcium, magnesium and sodium inputs via precipitation are thought to reflect the proximity of the ocean.

AN - 13876594; S198308080 AB - A brief description is given of the procedures involved in the implementation of nonpoint source pollution control measures for Prairie Rose lake, Iowa, under the USDA experimental Rural Clean Water Programme. Prairie Rose lake is a eutrophic water body in a farming district, selected as one of the 13 demonstration projects under the programme, which offers 75 per cent grants towards the cost of better land management practices for prevention of erosion and nutrient loss in runoff. Other measures involve provision of terraces and tile drains to control the runoff and improved timing and application rates for fertilizers. A summary of the progress achieved in the implementation of such measures to date is given, while a lake water quality monitoring programme has been instituted to assess the effectiveness of the pollution control methods (no results available).

Soil scientists, sanitarians, and contractors worked on different aspects of the soil potential index components in order to calculate reliable figures. A table lists 47 local soils and their SPI. Although all ratings apply only to the local area, this pilot study provides several advantages. Residents have available better information on corrective measures, local regulations, uniformity of procedure, and costs involved.

A diapause stock in which 79% of the larvae diapaused under crowded conditions and 40% diapaused under uncrowded conditions was maintained by selection. Outbreeding of adults from this diapause stock to those from a non-diapause stock resulted in 36% diapause under crowded conditions and 6% diapause under uncrowded conditions. The rate of termination of larval diapause is inheritable and temperature dependent. These data seem to explain the seasonal trends in percentage larval diapause among E. cautella infesting citrus pulp during storage. Larval diapause was induced in groups of larvae by crowding in mass cultures and in single larvae by rearing on a small amount of fresh diet or on a larger amount of fresh diet containing residual diet from crowded cultures. The diapause-inducing effects of this residual diet could be removed by extraction with lipid solvents. Some activity was demonstrated when the extract was dried onto fresh diet.Original Abstract: INDUCTION DE LA DIAPAUSE CHEZ EPHESTIA CAUTELLA: INTERACTION ENTRE LE GENOTYPE ET LA DENSITE L'induction de la diapause larvaire d'Ephestia cautella (Walker) depend du genotype et de la densite larvaire. Des croisements a l'interieur de la souche diapausante donnent 79% de diapause aux fortes densites larvaires et 40% aux faibles densites. Les croisements des adultes de cette souche avec ceux de la souche non-diapausante donnent 36% de diapause aux fortes densites et 6% aux faibles densites. La frequence de fin de diapause est hereditaire et depend de la temperature. Ces resultats peuvent expliquer les variations saisonnieres du taux de diapause E. cautella dans la pulpe de citron stockee. La diapause larvaire a ete induite chez des groupes de chenilles par surpeuplement dans des elevages standards, et chez des chenilles isolees par elevage sur une quantite limitee d'aliments frais ou sur une quantite abondante d'aliments frais contenant des residus alimentaires provenant d'elevages surpeuples. Les effets inducteurs de ces residus alimentaires disparaissent apres extraction avec les solvants de lipides. Une certaine action est observee par de l'extrait sec sur de l'aliment frais.

The effects of the walls were approximated by an image method. The correction of the diffusion coefficient of the sphere depends on the ratio of the slit width and the radius of the sphere. The theory was applied to the self-diffusion of water in swollen clays. Using the Stokes radius of a water molecule, the wall effects partially explain the reported decrease of self-diffusion in thin interlamellar water layers. The residual decrease corresponds to the immobilization of a small amount of water, of the order of half a monolayer at the clay-water interface. This is about equal to the commonly assumed hydration of the exchangeable cations. This interpretation of available data implies that there is no significant increase in the viscosity of the remaining interlamellar water and that there is no significant viscoelectric effect near charged clay surfaces.

Whenever the protective cover of vegetation is disturbed and th soil is tilled, the potential for erosion is increased. increased erosion not only lowers productivity but increases sediment in streams and lowers water quality. Prime farmland is the land that is best suited to producing food, feed, forage, fiber, and oilseed crops. Prime farmland produces the highest yields with minimal inputs of energy and economic resources, and farming it results in the least damage to the environment. There are about 346 million acres of prime farmland in the United States excluding Alaska, and 230 million acres were used for cultivated crops in 1977. From 1967 to 1975, about 8 million acres of prime farmland were lost to other uses. The loss of prime farmland to other uses means that more pressure is placed on nonprime lands to meet production demands. On a per-acre basis, the nonprime farmlands soils furnish the greatest amount of sediment and chemicals to streams. Environmental policy provides emphasis on preservation and conservation of prime farmlands. Much remains to be done to preserve the best cropland from irreversible conversions, protect is productivity from erosion, and manimize damage to the environment.

Work is under way in six of the 13 watersheds to improve water quality. Computer drawn maps are used to present information to farmers, identifying critical erosion areas on individual farms. The sediment yields computed by the model represent a net loss of topsoil from the watershed. To reduce erosion farmers are encouraged to change tillage and planting techniques, to rotate crops, or introduce permanent land treatment practies such as terraces. Stream-bank erosion is highly visible to farmers, but contributes less to the total sediment load than sheet and rill erosion on sloping cropland. The Soil Conservation Service and the Agricultural Stabilization and Conservation Service can provide farmers with cost sharing and technical help to make a properly functioning project. A hypothetical watershed and reduction estimates are used to illustrate the use of the ANSWERS model in planning.

Evaluation of pollutant concentrations in runoff at various distances downslope from an area where caged-layer poultry manure was applied regularly, indicated that for the conditions of this experiment a buffer area length to waste area length ratio of 1.0 was usually required to reduce concentrations to those measured in runoff from a similar plot receiving no manure. Less buffer area is needed if concentrations greater than background conditions are acceptable.

Those two tasks make two distinct, sometimes adversarial, sometimes complementary, roles for applied sociology. Reflecting different social values (participation, environmentalism) & different organizational backgrounds (public relations, scientific staffs) & different contributions to the process (facilitating or restraining development), an adversary relationship is very likely; but knowledge of preferences is essential for estimating effects by describing current orientations, evaluating effects as positive or negative, & in predicting future reactions & adjustments.

Water temperature and stream flow interacted to induce spawning; however, the former was more important. Spawning commenced at water temperatures near 8 C. Redds were normally in 6-15-cm deep water, about a quarter of the stream width from one bank and within 5 m of cover. The substrate was predominantly gravel and small pebble (0.2-3.8 cm). Spawning fish selected redd sites based on depth of water and substrate rather than on water velocity. Redds ranged in area from less than 0.1 m super(2) to nearly 2.0 m super(2) and averaged 3-4 cm in structural depth. Normally a single fish or a pair of fish occupied a redd, but occupancy by three to four fish was common. Most spawning activity occurred between 1300 and 1600 hours. Fry (15-20 mm long) emerged in 8 to 10 weeks and inhabited riffle areas. Absence of fry from pools occupied by adults indicated that cannibalism may occur.

Linear programming is concerned with the efficient use or allocation of limited resources to meet desired objectives. The determination of resource limitations was derived from interviews and other surveyed data. The linear programming model is a simulation which interprets activity within maximized or minimized objectives. There are two fundamental approaches to this modeling effort: (1) control the natural factors contributing to erosion and nutrient enrichment and rely on the model to specify which operational adjustments are most economical; or (2) specify the operational adjustments recommended for environmental purposes and rely upon the model to illustrate the impacts on the operation. The model has the capacity to vary and adjust a large number of components in the matrix in order to arrive at a solution. The method for testing various strategies is to translate a proposal into limitations, expansions or constraints, expressed in terms of the components in the matrix. The components outlined in the construction of the model are listed as follows: cow feeding and housing; purchase activities; cropping activities; capital availability; land and buildings expansion or liquidation; labor expansion, defined as owner/purchased; livestock expansion or reduction; machinery expansion or reduction; manure management; fertilizer utilization; taxes and subsidies; and soil losses. Through the manipulation of various components, a number of strategies may be simulated. Alternatives are displayed in a relative fashion enabling comparison between strategies and from a given strategy to the current conditions.

Natural resource base data generated by the program is categorized as: (1) soil surveys; (2) individual conservation plans; (3) broad multi-resource and erosion inventories (Farm Animal Concentration Studies, Important Farmland Inventory, Multi-Resource Inventory, Conservation Needs Inventory, and Erosion and Sediment Inventory); and (4) water resources studies. Soil surveys are the cornerstone of the SCS developed database, and an SCS nationally directed program for classifying all the soils in the country. The result of a soil survey is a published report which provides: (1) a soil map on an aerial photo base; and (2) a wealth of interpretive information for each soil. This means that distinctions can be made for areas as small as two acres, relative to crop production estimates; suitability for use for septic tanks, houses, road fill, and recreational areas; potential for erosion and sediment production; and, prime farmland locations. Conservation planning for individual units of land, based on the soil survey, not only documents land management decisions but also provides an additional compendium of resource data. SCS is unique in its assistance to individual landowners in evaluating their resource base, and making decisions to both develop and perpetuate it. SCS working through Districts, has an estimated 11,830 cooperators in the Lake Champlain Basin. SCS can make investigations of watersheds which have water resource problems including flooding, erosion, agricultural water management or water quality. Two such studies have been made in the Lake Champlain basin. One was in the Lake George village vicinity where high rates of erosion cause sedimentation and water quality problems in drainageways and Lake George. A second study was made on the Great Chazy, Corbeau Creek Watershed where problems with water quality were identified and where there is an agricultural water management problem. SCS has also made hydrologic studies of flood plains to show areas subject to periodic flooding for the Flood Insurance Administration.

The scope of concern is statewide across all land resource areas. Because of the specific concern in VT for the water quality of Lake Champlain and Lake Memphremagog, however, the 17 watersheds selected for detailed study as agricultural watersheds are all within these two major basins. Three lake watersheds also included in the study are Shelburne Pond, Harvey's Lake, and Berlin Pond. The Lake Champlain Level B Study and other studies on nonpoint source pollution established that the major areas of concern are cropland erosion, animal waste management, and milkhouse waste. Phosphorus has been identified as a major contributor to the problem of accelerated eutrophication in Lake Champlain, Lake Memphremagog, and some of the smaller lakes and ponds throughout VT. However, the nonpoint pollution problems were also affected by forestry activities and forestland conditions. The present activity and interest in whole-tree harvesting and generating electricity with wood chips is of particular concern in VT. All of the active farms within each of the 17 watersheds were identified and a 20% random sample from each watershed was selected for inventory. The smaller lake watersheds will be inventoried during the summer of 1980 at a somewhat higher sampling intensity. The farm inventory is scheduled for completion during the summer of 1980.

The National Environmental Policy Act and the Coastal Zone Management Act of 1972 are examples of the Congress ' more recent attitudes toward protection of water resources. In the past the federal government has exerted control over shoreland land use through the statutes on navigable waters, over which it has jurisdiction. The Federal Water Pollution Control Act Amendments of 1972 provide one example of this. Judicial decisions have promoted the extension of federal control over land use as it affects water quality. Uses of flood plains are also controlled by the National Flood Insurance Act of 1968, the Flood Disaster Protection Act of 1973, other legislation, and executive orders. Flood control projects, assistance in flood plain management, disaster relief, and flood plain acquisition are means of implementing these laws and regulations. A unified national wetlands protection management program is emerging from the piecemeal and fragmented jurisdictions, involving many federal agencies. Wetlands preservation is currently carried out through wetlands acquisition, providing migratory bird habitats through the Water Bank Program, the Corps of Engineers permit policy for construction activities (including dredging), small watershed management (discouraging channel improvement), the National Environmental Policy Act, and the Endangered Species acts.

AN - 15559779; 409597 AB - The amount and kind of seeds available from prairie hay used for reseeding disturbed areas are important. This study was conducted to determine the relationship of range condition and harvest date of prairie hay to the amount and kind of seeds present. The index of seeds available was based on the number of seedlings established after mulching greenhouse flats with prairie hay harvested at five monthly intervals from three range conditions. The abundance of 15 species in the mulched hay was related to the range condition where the hay was harvested. The amount of established seedlings of 21 species in the mulched prairie hay was significantly related to date of harvest of the hay. The number of established seedlings for 10 species was not related to either range condition or havest date.

AN - 15539281; 409695 AB - Disturbed roadsides are sometimes aesthetically degrading, highly erosive, and often difficult to revegetate. Indigenous plant species are generally slow to reoccupy the altered roadside environment under arid conditions making artificial revegetation necessary. Container stock of 13 shrub species was evaluated for summer survival following spring planting in 1976, 1977, and 1978. Common bladdersenna (Colutea arborescens ), antelope bitterbrush (Purshia tridentata ), Woods rose (Rosa woodsii ), sulfur eriogonum (Eriogonum umbellatum ), mountain big sagebrush (Artemisia tridentata vaseyana ), and white rubber rabbitbrush (Chrysothamnus nauseosus albicaulis ) appear to be the best shrub species for revegetating south slopes. Common bladdersenna also shows promise in revegetating north slopes where the other species have reduced survival and growth. JF - Reclamation Review AU - Everett, R L AD - USDA For.

AN - 15514837; 314748 AB - The secondary or subsequent effects of air pollution on the percent seed germination and on the chemical composition of seeds derived from azone-treated plants has not been reported. The objectives were to determine if ambient ozone influences: 1) seed germination and 2) percentages of oil and protein in soybean seed (Glycine max ). Seed sources were from soybeans grown in open-top field chambers with carbon-filtered air, in unfiltered air chambers, or in nonchambered plots. Percent oil and percent protein were determined by A.O.A.C. procedures 7.044 and 7.016, respectively. Seed germination was ascertained by standard seed test methods. Percent seed germination was statistically the same for seed produced in filtered and unfiltered air chambers; percent seed protein was significantly greater in seed produced in unfiltered air than in filtered air, but percent oil was significantly higher in seed produced in filtered air. Plants grown in nonchambered plots produced seed that had significantly lower germination but had protein contents similar to seed produced on plants from chambered plots.

AN - 15475121; 274101 AB - Field studies in Tennessee compared the relative susceptibilities of eight pine species to natural infection by comandra blister rust (Cronartium comandrae ) over an 8-yr period after planting. Pond, shortleaf, and slash pines were most susceptible. Loblolly and Virginia pines were less susceptible, and eastern white pine, red pine, and Japanese black pine were resistant. Differences in location of comandra rust needle infection were observed among pond, shortleaf, and slash pines. An apparent minimum 2-yr period was needed for developing rust stem cankers to cause tree mortality after natural direct stem infections through attached needles. All rust stem cankers detected during the first 5 yr after planting caused mortality the subsequent year on all susceptible species. Proximity of the alternate host, false toadflax, to infected pines was an apparent requirement, but false toadflax abundance was not correlated with subsequent incidence of rust-caused stem infection and mortality. Loblolly and shortleaf pine plantings should be avoided on sites where false toadflax would be close to the majority of planted pine seedlings.

AN - 15377774; 207735 AB - A clayey range site 56 km south of Gillette, Wyoming, was renovated in October, 1967, using a moldboard plow, disc plow, rotovator, blade, and atrazine applied in strips on April 30, 1968. Because of drought in 1977, there were no measurable differences in total herbage yield among all treatments 10-years after the renovation. However, the following year, 1978, above-average precipitation increased herbage yields, and differences among treatments were significant.

AN - 15338910; 163375 AB - The genus Ammophila is interesting because it encompasses the evolutionary transition from oviposition upon a single prey to progressive provisioning (Evans 1959, Powell 1964). Studies of representativespecies can clarify the successive steps in the evolution of a more complex behavior, i.e., progressive provisioning, from its simpler antecedents. The authors report on the method of provisioning followed by Ammophila aberti Haldeman, a species suspected of practicing delayed or progressive provisioning. In addition, they provide data onprey records, egg placement, and report observations that suggest facultative cleptoparasitism.

AN - 15324024; 144433 AB - Developments in research with behavioral chemicals are among the most significant advances in plant protection technology. Some of the more recent developments, in particular, have accentuated the extent to which chemical communication mediators are key links in interrelationships between various components of crop ecosystems and can multiply and enhance numerous exciting avenues for their potential employment in pest management programs. The author examines some of the possible reasons why to date these semiochemicals, which play such an extensive and vital role in the behavior of pests have not been capitalized to a greater extent.

At peak mid-summer temperatures, 2 thresholds were determined: (1) a decelerated phase of population growth (39 degree -46 degree C) and (2) a negative phase of population growth (>46 degree C). In 2 other runs, temperatures never reached the threshold of the phase of negative growth; however, the population growth decelerated at a lower threshold (31.6 degree -42.3 degree C) than in the mid-summer test.

(Monocotyledoneae: Haemodoraceae) in Panama. AN - 15295242; 121076 AB - This paper reviews available data on pollination ecology of Haemodoraceae and presents evidence for buzz pollination in Xiphidium caeruleum Aubl., a Panamanian bloodwort. Field observations were made on floral morphology, ontogeny, and the intrafloral behavior of bee visitors. Observations on floral color, odor, distribution of osmophores, anther dehiscence, visible and ultraviolet floral patterns are presented. Hymenopteran visitors were females of Paratetrapedia calcarata (Cr.), an exomalopsine bee, and both sexes of Euglossa imperialis Ckll. (Apidae: Euglossini). Female E. imperialis upon landing on the flowers, shivered their indirect flight muscles producing an audible "buzz," thus vibrating the stamens and entire flower. This buzzing behavior resulted in rapid pollen release from the androecial apical slits and was an efficient means of pollen collection used by these "orchid bees." Males of this species also visited the nectarless flowers of Xiphidium apparently to collect the components making up the floral odor. The use of these collected floral volatiles in mate attraction is still highly controversial, but is briefly reviewed in relation to pollination of Xiphidium .

Five subjects received dephytinized wheat bran the first 15 days followed by whole (nondephytinized) wheat bran the second 15 days and 5 received the 2 types in the opposite sequence. When dephytinized bran was consumed, the phytate intake (0.2 g/day) was one-tenth the intake when nondephytinized bran was consumed, but the total inorganic nutrient and neutral detergent fiber intakes did not differ. The overall results indicate that the phytate in 36 g of wheat bran each day did not exert a detrimental effect on trace element nutriture in this study. JF - IN "TRACE SUBSTANCES IN ENVIRON.

The amounts of copper and zinc in drinking water usually are too small to produce important increases in the amounts of these elements in diets. Occasionally tap water high in copper may be an important supplement to a diet low in copper. JF - J. ENVIRON. PATHOL. AND TOXICOL. AU - Klevay, L M AD - USDA Sci. and Educ. Admin. Human Nutrit.

The effectiveness of selected diffusion and kinetic processes for controlling the rate of acid product loss from the spoil particle were compared. Initially, the acid production rate in unweathered fresh spoil exposed to 20% O sub(2) appears controlled by the pyrite oxidation rate. However, the control of acid product loss rates from a partially weathered spoil particle decreased in the order: acid product diffusion > O sub(2) diffusion > pyrite oxidation.

It is shown that much of the chloride in the sludge is leached into the soil profile during the first year and nearly all of it within 4 years. More nitrogen was leached in the first 2 years than in the second 2 years and ammonium nitrogen predominated in the soil. After 4 years the sludge in the trench was near or at stabilization and zinc was the only metal in detectable levels in the soil beneath the trenches. The environmental effects of entrenchment of digested sludge appear to be primarily on ground water and the contamination would be site specific. JF - Journal of Environmental Engineering Division.

Rates of methane production were measured and kinetic parameters determined with reference to a previously published kinetic model.

The model is written in FORTRAN and users do not need computer programming experience. Eleven commands are provided that can be used in any sequence for any watershed. It was designed to predict nutrient yields for individual storms on small drainage basins and to route them through streams and valleys of large ones. The modified universal soil loss equation is used to predict sediment yield and individually adapted loading functions to predict phosphorus and organic nitrogen yields. A function dependent on surface and sub-surface flow is used to estimate nitrate yield. The model was tested on a drainage basin in Texas and gave realistic results.

It has been shown to be capable of measuring a mean depth of 1.2 m. Aerial photography is considered to be a research tool, rather than an operational prediction technique, because of lag time between photography and result and the need for ground control surveys. For high accuracy, a sampling method consisting of a northeast /southwest grid system (perpendicular to the direction of the predominant wind) was shown to be superior for all types of snow cover. The number of samples needed varied inversely with the total watershed snow cover.

The main hypothesis tested was that quality (salinity and nitrate) of well water should be better in areas with permeable soils and geological formations than in areas where permeability is less, assuming other influential factors to be similar, a hypothesis not borne out in fact since the analysis reveals that other sources of variations such as soil /waste water and soil/plant /ground water interactions are also important.

It is shown that, for deep aquifers, in which renovated water is collected from wells, the nitrate peak of newly infiltrated water would flatten out before the water is collected at the well. It is indicated that separating high nitrate portions of water would not be practical. However, in shallow aquifers, it is suggested that more than 60 per cent of nitrate could be recovered in 25 per cent of the renovated water if the infiltration is less than 1 ft per day.

Detailed results are presented showing that perennial grasses have superior capacity compared to maize to remove nitrogen from soil treated with large amounts of waste water effluent. The grasses are also most likely to yield the most protein per hectare, but the least digestible dry matter, in effluent-treated systems. Both the grass and maize can effectively renovate large amounts of waste water effluent.

Use of snow areal extent measurements in snowmelt runoff prediction in the Rio Grande shows promise, but with the short period which the study encompassed, it is difficult to assess its long-range impact. Currently (1978) available Landsat imagery is of sufficient quality and resolution for accurate snow mapping by photo interpretative means. Delay in image delivery, occurrence of cloud cover, and a 9-day interval between satellite coverage diminish to a significant extent the amount of reliance one can place in using snow cover as a forecast parameter. Three methods of using snow cover area in forecasting have been explored and have proven successful. A statistical regression model relates snow cover to season volume flow directly. An empirical method relates seasonal snowpack depletion to seasonal and annual yields. A computerized simulation model provides short-term and seasonal forecasts using snow cover as an input variable.

AN - 13900139; S198102305 AB - Nuisance organisms proliferate on surfaces of wells, particularly on the bottom, and it is therefore important to ensure uniform dosage of chlorine throughout a well. This may be achieved by introducing disinfectant solution through a pipe which is gradually withdrawn from the well or with granular disinfectant of carefully selected particle size. Establishing circulation, checking residual chlorine levels and adding more as required, eliminates much of the guesswork of disinfection.

In general, failures occurred where proper design and maintenance were not provided. Ninety-nine percent of the farm ponds performed as designed without failure. The storm was massive, 2.4 times the 100 year-24 hr rainfall and 69% of 6 hr PMP. The Soil Conservation Service floodwater retarding structures are not designed for so large a storm but they performed well with only minor damage. Turbulence and scouring occurred in and beyond some emergency spillways due to fences and cow paths. Hop and skip flow conditions initiated by surface irregularities caused minor damages in the $1,000 to $5,000 range. Some farm pond failures can be attributed to debris plugged screens across spillways. Much more damage and inundation of urban areas would have occurred without the successful performance of the retarding structures.

Over 160 bays were delineated, thus indicating that they are major landforms in the area. Bays differed from those reported in other regions by being less elliptical, more westerly oriented, and lacking well-developed rims in any specific quadrant. Bay location and size are apparently controlled by landscape and sandy parent materials as evidenced by association with less distinct natural depressions with similar orientation as the related geomorphic surface. Soils on bays of recent surfaces have weaker profile development compared to Pleistocene upland bays. More than one period of bay formation is suggested by differential pedogenic development and geomorphic positions. Data indicated Carolina bays were formed by the alteration of poorly drained areas on undissected Coastal Plain interfluves. Wind and waves were suggested as factors in bay formation based on well-sorted sands of elevated rims, ' dune-like ' character, and silt content of possible aeolian origin.

AN - 733487059; 16660775 AB - Cryoprotection of suspension cultures of sugarcane cells (Saccharum sp.) during freezing to various temperatures was tested using glucose, dimethylsulfoxide, and ethylene glycol at various concentrations, alone and in combinations. Viability of the thawed cells was assessed by triphenyltetrazolium chloride reduction, cell growth, and microscopic examination. Enhanced cryoprotection-as much as a doubling in viability value-was achieved by employing glucose and dimethylsulfoxide in mixtures, as compared with the lesser cryoprotective effect of either compound alone, at 1.9 molar total concentration in all cases; the mixture was most effective at a concentration of about 1.9 molar, with a molar ratio of the two components of about 1:3, respectively. Much of the increase in viability value arose from a decrease in toxic effect that came about through mixing the cryoprotective agents. Binary mixtures containing ethylene glycol and either glucose or dimethylsulfoxide were less effective and more toxic than comparable glucose-dimethylsulfoxide mixtures. Use of the optimized latter mixture allowed freezing of these tropical cells to -23 C with little decrease in survival, or to -40 C, still with the capability for delayed growth.

The ordinances were developed prior to a new soil survey of the district which will identify critical slide prone soils. Orderly development within Hamilton County may then be planned. Training of city employees is required, so that they may select the proper erosion control practices and inspect their installation. Enforcement of the provisions of the ordinances is aided by the use of checklists of actions to be taken by each developer or engineer. The focus of the ordinances is to maintain slopes in a stable condition, ensure safe loads on slopes, and maintain adequate drainage on the site and adjacent sites, and prevent ponding of water, erosion, and sedimentation. Plans must show the measures, temporary and permanent, which will be taken to comply with the ordinances and the timing of each action.

Some 20 states have legislation designed to control erosion and sedimentation; all states are affected and therefore need a legislative program. Land use planning should be conducted by local officials to develop the most appropriate sites. Erosion and sediment control techniques need to be cost effective. Communities and their citizens need to become aware of the problems and the means of solving them. Specific educational projects should be directed to contractors, developers, and inspectors. Builders and developers should be encouraged to adopt and follow a code which promotes urban land conservation and reduces erosion and sedimentation. Erosion may be controlled by mulching, grading, diversions, grade stabilization, grassed waterways, and storm sewers. Sediment may be controlled by vegetative filters, sediment traps, and sedimentation basins. Runoff may be controlled by ponds, infilitration trenches, perforated parking lots, and above or below ground storage.

Early planning is used to locate structures and roads, retain existing vegetation, and minimize earthmoving to reduce erosion. Appropriate construction of temporary measures and final vegetation, all reduce erosion and runoff problems. Erosion prevention is preferable to sediment control. Erosion reduction can be achieved by proper location of access routes, vegetating or mulching surfaces, land grading, use of grassed or lined waterways, appropriate storm sewers and grade stabilization structures, and subsurface drains. Sediment may be trapped by straw bale dikes or vegetative filters, and sediment basins, which can remove 80% and 90% of sediments, respectively. Runoff management systems include such practices as dams, excavated ponds, infiltration trenches, perforated parking lots, parking lot storage, rooftop storage, and underground tanks. All the control practices will be enhanced by development of government policies, public awareness, and education of individual contractors and construction workers.

No grading or building permit may be issued until the developer submits a grading and sediment control plan. There are seven important technical principles for control of erosion and sediment upon which technical standards and assistance are based: exposed the smallest practical area of land; expose for the shortest time possible; temporarily stabilize critical areas with vegetation or mulch; install and maintain sediment traps; accommodate increased runoff; establish permanent vegetation and structures as soon as possible; and fit the development plan to the topography and soils. Soil Conservation Districts (SCD) provide assistance during each stage of development, including the land acquisition stage, preliminary planning stage, preconstruction stage and construction stage, and also provide information, education and evaluation. The Maryland program continues to be innovative and evolving. For example, stormwater management is becoming a new and important part of the program. It is now required in more than 10 counties by SCD policy, county executive order or ordinance.

Adult Rs in 78% of the households completed interviews, providing 2,034 cases for the analysis. Cluster analysis reduced the data to a relatively compact description that reveals inherent structure & relationships. Based on 47 attitudinal questions it was found that there were 5 different typesof attitude domains represented in the data; affinity for wild predators, affinity for farm animals, hunting attitude, nonconsumptive importance of wild animals, & affinity for domestic pets. Also, there are 9 different types of people based on the 5 attitude domains. The types range from dislike all animals to like all animals with various combinations of the 5 attitude domains represented in between. How Americans relate to animals is a complex matter. The 9 types of individuals were distinct in their profiles regarding affinity for animals, importance of consumption & nonconsumption, & concern for animal treatment. Somewhat surprisingly, sociodemographic characteristics & residential location did not provide much in the way of distinct descriptive information about the 9 types of individuals. It was concluded that there is structure & order in Americans' attitudes toward wild & domestic animals, their treatment & utilization, but that such structure & order are not well described by sociodemographic characteristics or location of residence (Ru, Ur, or by different regions of the country).

The 208 Planning Group developed a three-phase study plan. As part of Phase I, a statewide inventory of erosion was conducted for different land uses. During Phase II, sub-basins with high pollution potential were investigated to determine which nonpoint pollutants were present, their source and the best management practices (BMPs) needed to control them. Phase III involved continued study and monitoring of two priority sub-basins. Highest erosion rates occur on surface mines, sanitary landfills, construction sites and shorelines; however, almost two-thirds of the state soil loss occurs from cropland. The highest sediment delivery rates occur in the Piedmont and mountain state areas. Almost half of the erosion occurs on 2.3 million acres of high water erosion hazard cropland. This means that over 36 million tons of the state 's annual soil loss of 79 million tons comes from 7.4% of the land. The proposed multi-year program includes BMPs to reduce erosion on cropland to 5 tons/acre/yr. Installing and maintaining these BMPs will cost an estimated $281 million as of October 1978. On-site costs of installing these practices average $75/acre. North Carolina landowners now spend $9 million/yr to install erosion and sediment control practices. Even with active cost-sharing government programs, less than half the needed $28 million/yr is being provided.

Onsite and offsite resource problems that were identified and measured, include those related to reduced agricultural production and increased production and maintenance costs per unit of output which can result from erosion, sedimentation, impaired water quality and reduced soil moisture. Quantified data from the use of universal soil loss equation, research studies of extension, universities and Agricultural Research Services (ARS), and compiling of experienced crop yields were evaluated with computerized methods such as the Crop Budget System (CBS), linear programming and value of agricultural production. CBS is a system designed for efficient storage, rapid retrieval, use and revision of crop budgets used to evaluate alternative systems of BMP. Qualifying statements on nonmonetary impacts, primarily environmental issues, were also discussed. Procedures describing the estimation of installation, operation and maintenance costs of BMP were included, as well as methods to assess income foregone and adverse environmental effects.

Monthly water table measurements differed for each piezometer throughout a 4-year study period, indicating a perched water table. There was a water table at the greatest depth on only 5 occasions during the study period. On all but a few occasions, a water table was encountered at the 2 shallower depths. Morphological properties and seasonal precipitation were related to the water regime. The perched water table fluctuated in a continuous zone of saturation in the B horizon above the horizons containing appreciable amounts of plinthite. A discontinuous zone of saturation was bounded on the bottom by the B3 horizon. The piezometer that had perforations in the C horizon showed no water table, which indicated that a ' dry ' zone exists between the perched and regional groundwater tables. Fluctuations in the depth to perched water corresponded to seasonal precipitation patterns.

Experience and research have shown that many resource management systems are highly effective in protecting and improving water quality. The resource management system selected may include agronomic, managerial, and structural practices that reduce nonpoint source pollution and protect water quality. The best resource management system is one that keeps the water where it falls, protects the resource base, and maintains water quality of the water that runs off. It was suggested that such proved resource management systems can be used in achieving national goals of improved water quality, and because of the recognized effectiveness of conservation practices and resource management systems in controlling nonpoint source pollution, many of them can be selected and listed as BMP in Section 208 Water Quality Management plans.

The influence of temperature, substrate and operating conditions on the maximum specific growth rate, the kinetic rate constant and the attainable methane production rate were determined. Data were obtained using dairy cattle manure, sewage sludge and municipal refuse. Increasing the substrate loading rate increased methane production up to a limiting value, and for a given loading rate, higher influent concentration and longer retention times gave higher methane yields than low influent concentrations and shorter residence times, up to the point where overloading occurred.

Cultivation treatments included conventional and no-till practices for both silage and grain crops. For silage, stalks were removed, while for grain crops the stalks were chopped and left on the surface. Even though the sediment TOC and COD levels from the no-till grain and silage practices were considerably higher than those from conventional cultivation, the magnitudes of TOC and COD losses from conventional treatments were from 6 to 13 times greater than for no-till practices owing to larger volumes of runoff and associated soil losses. Average 5-day BOD values for both treatments were similar, although subject to seasonal variation. A linear regression equation related annual concentrations of aqueous COD and TOC irrespective of treatment; the levels of both being increased as a result of organic matter released from crop residues. No-till practices reduced the losses of total (sediment plus aqueous fraction) TOC by 74 and 85 per cent for grain and silage harvesting respectively.

Experiments were carried out in 75 cm i.d., PVC columns fitted with porous ceramic cups under an applied air pressure. Correlation coefficients for the ionic salts were determined for the product of electrical conductivity and gravimetric moisture contents and for the sodium and calcium concentrations in sewage effluent. The results were not highly correlated and it is suggested that, though porous cups are convenient, the soil solution extracted from them does not give a precise indication of ionic salt, sodium and calcium ions.

When an unlabelled calcium chloride solution was applied to the soil column following a calcium-45 labelled solution of only one-tenth the volume, most of the exchange occurred at the front of the incoming solution. As a result the concentration of calcium-45 in the percolate at one pore volume was much greater than the initial concentration in the labelled solution, while complete removal of the initially adsorbed ions occurred after passage of an amount equal to two pore volumes. An approximate model is presented which adequately represents this behaviour. JF - Soil Science Society of America.

No tillage, sweep or disc cultivation treatments were employed during the fallow period for wheat residue management and weed control. All the parameters investigated declined in the treatment order no-tillage, sweep and disc cultivation and the net returns for sorghum production using either no-tillage or sweep tillage were respectively four and two times greater than with disc tillage, the method most widely used at present following irrigated wheat crops on the Southern Great Plains.

At times, soil mapping delineations do not represent adequately conditions as stated in the map unit descriptions. Digital analysis of LANDSAT multispectral scanner (MSS) data provides a means of accurately delineating and quantifying soil map unit composition. Digital analysis of LANDSAT MSS data collected on 9 June 1973 was used to prepare a spectral map for a 430-ha area in Clinton County, Indiana. Sixteen spectral classes were defined, representing 12 soil and 4 vegetation classes. The 12 spectral soil classes correlated with soil drainage characteristics and were grouped into four drainage classes. The four spectral vegetation classes were grouped for convenience into one vegetation class. The soil delineation produced using these groupings were compared to a conventionally prepared soil map. Three map units were investigated in detail: (1) Mahalasville silty clay loam, poorly drained; (2) Reesville silt loam, 0 to 2% slopes, somewhat poorly drained; and (3) Xenia silt loam, 2 to 6% slopes, eroded, moderately well drained. Results indicated that soil drainage characteristics can be identified. Correlation of drainage characteristics with soil series allows for the composition of soil map units to be accurately ascertained.

Voluntary programs are acceptable in the Southeastern United States. Plans developed under Section 208 of the Act must include best land management practices, priorities, implementation schedules, evaluation programs, and reporting systems. A key factor is the assessment of types and locations of any water quality problems. Failure of voluntary plans after several years trial may require regulatory approaches to be taken.

These drain systems are installed to control groundwater and serve as artificial subsurface drainage arteries for salinity management in an irrigated area. Of the 209 examined installations, 141 were installed by the trench method and 68 by the trenchless method. All systems were installed in calendar years 1975 and 1976, and all utilized perforated corrugated plastic tubing, of 4- to 6-inch diameter size, and nylon fabric filters. The evaluations reveal the ability of the 209 drain systems to discharge flow in the presence of a groundwater flow source, with the surface of the groundwater variously ranging from 2 to 6 feet below the ground surface. The data displays a strong general disparity in the unit flow for systems installed by the trench and trenchless methods, with the trench method showing a noticeably higher flow performance for seemingly similar conditions. In repeated instances, the flow performances of systems installed by the trenchless method were less than that believed to be needed to satisfy minimal drainage coefficients for the area.

Applying the model to two Illinois soils, it was found that as many as two available workdays in April and 19 days in May are gained by installing a recommended subsurface drainage system. The optimum drain spacing based on the timeliness benefit of earlier corn planting ranged from 24 to 61 m, depending on permeability and soil type. The average annual timeliness benefit for installing the optimum subsurface drainage system was $37 to $156/ha.

A spring-loaded housing was developed for the elements for either drill-hole or pit-face placement. The sensors were calibrated under various matric potential, salinity, and temperature conditions. An initial field test with 72 sensors was conducted under irrigated coal mine spoil conditions. Laboratory and field results indicated reasonable instrument precision over a wide range of matric potential and salinity. The correlation between sensor output and water content in the field was best where the mean of several sensors was used.

BROOK is a water-yield model for small areas; it was not designed to simulate flood peaks or watersheds with multiple aspects. It operates with a daily time interval, and requires daily precipitation and daily mean temperature as input variables. BROOK can simulate hardwood , conifer, mixed, cleared, and regrowing vegetation types, but these types must be uniform over the watershed. Partial cuts cannot be simulated. Evaportranspiration is divided into five components and streamflow into three components. The model was calibrated and verified using experimental watersheds at the Hubbard Brook Experimental Forest in New Hampshire and the Coweeta Hydrologic Laboratory in North Carolina. BROOK was designed to study the response of streamflow on different slopes and aspects to cover changes caused by harvesting and regrowth or by conversion from hardwoods to conifers. It has also been used to examine streamflow resonse to different hardwood transpiration characteristics, to estimate soil-water deficits prior to floods, to stimate soil water available for tree growth , as a base for nutrient concentration modeling, and as a teaching tool.

The active agent is thought to be a zinc peroxide complex or polymer containing activc oxygen. When these reagents were applied to cotton fabrics, antibacterial activity was imparted which lasted throughout 50 home launderings. This treatment is effective against odor causing bacteria such as S. epidermidis and pathogenic bacteria such as S. aureus. For simplicity the name "Permov" is used to describe the finish. The treat ment consists of applying aqueous zinc acetate, hydrogen peroxide, and acetic acid solution to the fabrics and curing them for 5 min at 85C. Other curing temperatures (23 160C) were studied, as well as the effect of varying solution concentrations. Fabrics given these treatments had 0.2-0.8% peroxide and 0.3 3.4% zinc prior to laundering. Even after 50 launderings the fabrics retained 0.1-0.2% peroxide and 0.2-0.4% zinc. Disinfecting of fabrics with sodium hypochlorite before Permox treatment was not advantageous in maintaining antihacterial activity on repeated laundering Breaking strength, stiffness, and moisture regain of the treated fabrics arc comparable to untreated fabrics, but a moderate loss of tearing strength was observed.

The world must double food production in the next 25-30 years; production of food and fiber requires great amounts of water. About 90% of human food comes from cultivated crops, principally cereals, which occupy some 10 % of the earth 's land area; grazing and pasture land occupy about 20%. Food and fiber production consume more water than other human uses, about 80% of all consumption. Over 60% of rainfall on the land surface is used by vegetation or evaporates directly into the atmosphere, while 65%-95% of water indomestic or industrial use returns to streams or underground reservoirs. World food production can be increased and water supplies conserved through water resources development measures, including: (1) more efficient use of available water by improved irrigation management, drainage, soil management, and fertilization; (2) improved production in rain-fed areas; (3) development of additional land which does not require large amounts of supplemental water; (4) developing new irrigated areas where water supplies and arable land exist; (5) aquaculture; (6) bettermanagement and use of ocean, lakes, and grazing land food resources; and (7) increasing productivity per unit resource input with improved technology.

A valid taxonomic approach would bring order to a classification system in an orderly, not arbitrary, manner. This is done by addressing three basic questions to each specific solution scheme: (1) how good will the answer be, (2) how can the answer be obtained, and (3) how much is it going to cost. These three questions lead directly to the major areas of differentiation: (1) the math model, (2) the method of solution, and (3) the technique of computation. The math model is the analytic representation. The method of solution and technique of computations are distinct parts of methodology. The development of an unsteady open channel flow computer model for large scale field use is needed. Future studies will require: (1) the classification and selection of the important solutions to minimize the study effort, (2) the development of a means to relate the hydraulic and hydrologic properties of channel system and hydrographs to the responses so that the results can be reliably generalized for field applications, (3) the selection of the scope of the study to reflect field situations, (4) the development of a single comprehensive computer analysis model to minimize differences between programmers, (5) the execution and interpretation of test data to develop logical dependable data-directed techniques for an operational computer program, and (6) the development of an operational, comprehensive, data-directed, user-oriented, efficient, accurate, reliable, and optimized computer model for unsteady open channel flow problems.

Erosion data were collected for a 3 1/2-year period from 1969 through 1972. Erosion on bare control plots averaged 3.4 metric tons/sq km per day for water years 1970 through 1972. Erosion was reduced an average of 44% and 95% by tree planting and straw mulching, respectively. Daily erosion rates were consistently higher during summer periods than during snowfree winter periods, presumably because of greater rainfall energy during the summer. Dry creep accounted for at least 15% of the total annual erosion for the years sampled and was as high as 40% in 1971. The erodibility index was a poor predictor of erosion for rain periods. Observations in the area suggest that wind was an important erosion factor on the steep slope studied. The median particle size of eroded materials D sub 50 tended to decrease throughout the summer and fall until mid-October when it abruptly increased.

Variate transforms were based on orders of exponentiation. The set of distributions included the log-normal. A partial basis for use of these functions in hydrology was demonstrated by establishing some required properties. A concept of mixed samples of zero and nonzero elements forming nonseparable sets of virtual and real elements was introduced to establish a physical lower limit of samples data independent of functional bounds.

It was suggested that the bedload and the upland must be carefully analyzed to determine the critical energy level which is the first step in the design of a successful in-channel sediment trap. The procedure provided design data needed to proportion the sediment trap to trap bedload sediments by reducing flow velocity through the trap.

The acid whey, with a pH of 4.39-4.61 and nitrogen concentrations of 1.2-1.4 mg/liter, is generally heated to render proteins insoluble. Several acid whey proteins are resistent to heat denaturation. The lime-sulfide dehairing waste water, at pH 12-13, contains dissolved hair protein, sulfur compounds, and high concentrations of dissolved and insoluble solids and BOD. At room temperature, the two-waste mixture, containing 20-40% tannery effluent, spontaneously produced centrifugeable precipitates with 17% of the total nitrogen and clear liquor. Heating of the supernatant for 15 min at 70C extracted an additional 20-25% of the total nitrogen; all soluble protein was removed from the supernatant by heating when tannery effluent content was 15-30%; lactose, nonprotein nitrogen, and excess sulfide remained in solution. Acid whey and tannery waste, mixed in a 4:1 ratio at pH 9.5 and 25C, produced spontaneous precipitates; the supernatant was steam heated to 80C for further protein removal. The heat-induced precipitate had higher amino acid concentrations than the spontaneous coprecipitates. The COD content of the supernatant was reduced by 16% after coprecipitation; total sulfur and total solids contents were 26 mg/ml and 8.5% by weight, respectively.

This new trend is not limited to counties adjacent to metropoli tan areas. The association between 11 demographic, economic, and regional characteristics of nonmetropolitan counties weakened considerably between the 1960-70 and 1970-75 periods, as these areas shifted from a predominant pattern of declining or nearly stationary population to one of growth. Some of the major regions of the country deviate substantially from the national pattern in the factors associated with recent nonmetropolitan change and in the strength of the associations, but the existence of a reversal of trend is very pervasive.

Agricultural land, especially cropland, produces the largest amount of sediment annually. The next largest source of geologic erosion. Range and forest lands and construction activities are about equal in the amount of sediment produced. Erosion control is important to maintan productivity on agricultural and forest lands and to aid in sediment pollution control. Procedures have been developed for predicting erosion and sediment yield. Technology is available to reduce the amount of erosion and sediment induced by water from most land areas. In some places, additional research or data are needed to improve the peformance of erosion control systems or reduce the cost, or both. The quality of installation and maintenance of erosion control measures is still one of the major problem areas.

The sediment control program, based on a set of basic principles, was developed and implemented beginning in Montgomery county in 1965. Technical principles for controlling erosion and sediment were also developed. The present state law requires that all development must have a sediment control plan approved by the soil conservation district before any construction begins.

Female reproductive behavior and fecundity were not affected. The lethal effect was manifested during late embryogenesis. Egg fertility was not influenced among untreated females that mated with males that had been exposed to the IGR. The effectiveness of this treatment suggests that methoprene may be useful in controlling the cigarette beetle on packaged commodities.Original Abstract: DIMINUTION DE LA REPRODUCTION DE LASIODERMA SERRICORNE AVEC UN REGULATEUR DE CROISSANCE DES INSECTES, LE METHOPRENE L'exposition de la femelle adulte de Lasioderma serricorne au contact d'un papier filtre traite avec du methoprene, regulateur de croissance des insectes, a entraine une reduction significative de la reproduction, en fonction de la dose. Ni le comportement, ni la fecondite ne furent affectes. La fertilite des oeufs n'a pas ete touchee chez les femelles non traitees qui s'accouplerent avec des males ayant ete exposes au methoprene. L'efficacite du contact avec le methoprene, en empechant la reproduction des femelles de L. serricorne, aussi bien chez les femelles accouplees que chez les femelles vierges, et l'effet prolonge du methoprene, permettent de considerer favorablement son usage pour le controle de cette espece. Son emploi le plus efficace devrait concerner la protection des produits conditionnes en emballages.

Consumption of food containing 2.3 pptr or 2.3 ppb TCDD caused no mortality, no reduction in food consumption or growth, and no fin erosion. Consumption of diets containing 2.3 ppm TCDD caused an average mortality of 50% and 88% in 61 and 71 days, respectively. Feeding activity and growth were also reduced, and fin erosion and liver pathology increased. These data indicate that the 'no-effect' level for survival, growth, feeding activity, and fin erosion in rainbow trout receiving TCDD orally is between 2.3 ppm and 2.3 ppb.

Studies were conducted to quantify the effects of various parameters on flocculation processes. Unhairing effluents were obtained from a tannery which processes fresh hides in a paddle vat with a lime-sulfide hair pulping process and from a tannery which processes salt-cured hides with a hide processor and a lime-sulfide hair pulping formula. Fourteen coagulant aids were evaluated as flocculants for the unhairing effluents. These include a series of synthetic, high molecular weight, water-soluble, acrylamide-based, polyelectrolytes manufactured by Allied Colloids of Ridgewood, New Jersey; a series of inorganic colloids manufactured by Georgia Kaolin of Elizabeth, New Jersey; and other polyelectrolytes. Composition variables, including pH, salt content, suspended solids, and soluble organic material, were measured in several fractions of the unhairing effluents, including unscreened effluent, screened effluent, solids settled for 30 minutes, and supernatant liquor. Polyelectrolyte performance was evaluated with respect to effluent age, salt content, combined age and salt content, effluent dilution, effluent pH, and screening.

The addition of lime to a dispersive soil converts the soil to a nondispersive state immediately. The modified hydrometer (turbidity) test is the most reliable field test for quality control of lime-soil construction for the Bluff Hills. The addition of lime changes Proctor 's moisture-density relationship. Optimum moisture is increased by about 2 to 3 percentage points, and the plasticity index is reduced with curing. The laboratory pinhole test is the most reliable measure of erosiveness and future performance of the earth structure. The writer suggested that the airwater permeability ratio test (Agriculture Handbook No. 60) would correlate well with the pinhole test. Research is needed to determine the amount of effective clay, expressed as a fraction of the total soil matrix, to provide a non-erosive structure. Dispersive soils can be used to backfill around principal spillway pipes or other structures traversing a dam laterally.

In May 1976, the Government Services Division of Western Union began development of a data communications system using the meteor burst concept. The first phase of the project consists of 2 master stations and 160 remote data sites in 11 western states. A typical remote site has sensors that measure the water equivalent of the snowpack, rainfall, and air temperature. The central computer automatically instructs the base stations to poll remote sites at the desired frequency. With the SNOTEL system, which provides snow resource data almost instantaneously , forecasters should be able to determine more accurately the volume and distribution of the next summer 's snowmelt runoff.

In the Great Plains and in other parts of the country, the potential for wind erosion damage can be expected to increase as new lands are brought into cultivation to meet the growing needs for food and fiber. But, since the days of the Dust Bowl, research and technology have provided many tools for dealing with this important problem. During the drought of the past several months, a major portion of the land in the Plains was protected by conservation practices which helped to hold the soil in place and to diminish the adverse effects of the weather. As new lands are brought into production and those presently cropped are subjected to more intensive use, efforts must be accelerated to insure that conservation technology keeps pace with the needs of American agriculture.

AN - 733323469; 19305596 AB - Soil moisture and the nematode population density in aldicarb-treated soil influenced control of the sugarbeet nematode, Heterodera schachtii. Greater numbers of nematode larvae infected 14-day-old sugarbeet seedlings growing in aldicarb-treated soil at 20-30% than at 80-100% field capacity (F. C.), and plant growth was inversely related to nematode infection and the nematode population density. Compared with that of control plants, plant growth increase also was greater at 80-100% F. C. when the nematode population was above 1.8 larvae/gm soil. A nematode population of 1.8 larvae/gm soil did not significantly affect sugarbeet yields. Aldicarb gave less control when soil moisture levels dropped to 20 and 50% F. C. at nematode populations of 3.5 and 6.2 larvae/gm soil. More effective control was obtained wth soil moisture levels at or above 80% F. C. This difference was attributed to continued activity of the toxicant in the rhizosphere at the high moisture level.

Preliminary experiments using activated carbon treatment, sand filtration, and addition of SO2 and lime have produced a product similar in composition, color, and firmness to that of fresh brines. Iron contamination of the recycled brine and resulting discoloration are attributed to corrosion of the steel drums in which the brine was stored. Discoloration caused by iron contamination was not apparent in brines which had been adjusted to 15,000 ppm SO2 or had been stored for 21 weeks at room temperature. To minimize loss of SO2, it is suggested that brines which are to be recycled be prepared immediately before the harvest. Brined cherries which had been repacked in water for shipping to finishers showed oxidation and softening after long term storage. It is suggested that an engineering study and cost analysis being conducted at Michigan State University will provide data on the economic feasibility of brine reclamation.

Federal and state regulations have required potential developers to submit environmental impact statements in advance of new projects and to design developments which meet environmental criteria. The Environmental Quality Laboratory was established in 1975 by the General Development Corporation to aid developers and planners in meeting these requirements. Laboratory facilities include two chemistry labs, a biology lab, a bacteriology lab, a library, and a computer room. The services provided by Environmental Quality Laboratory include compliance monitoring, environmental planning of new community developments, and redesigning of older plans for residential communities. The laboratory also conducts a monitoring program of Charlotte Harbor, Florida, which includes regular evaluations of water quality and biota. The laboratory is currently testing new methods of waste disposal and treatment for the Port Charlotte area.

A more flexible approach to planning and evaluation is presented that recognizes the interaction of production and consumption through the use of commodity demand curves. Use of the concept of consumer surplus permits measurement of the differential impacts on producers ' and consumers ' welfare. Quadratic programming is suggested as a consistent means of quantifying these differential impacts. That such an approach is empirically feasible is verified by a recent study of the California agricultural sector which, employing a quadratic solution procedure, was used to estimate the value of goods and services and producer and consumer tradeoffs. Two major limitations in the particular application of this approach may be the lack of good regional demand estimates and the exclusion of water demand relationships for other uses, such as fish and wildlife. These problems, however, can gradually be met as data bases and methodology improve. (Bell-Cornell) JF - Water Resources Bulletin Vol. 13, No. 3, p 489-498, June 1977. 1 fig, 1 tab, 13 ref.

Proper grazing management has made it possible to water and feed his 750 head of cattle on 5,500 acres near Canadian, Texas, despite the drought that has besieged this area. Critical factors affecting the flexible grazing system used are time and amount of rainfall, forage growth, brush spraying, and sparseness or proliferation of brush.

Local farmers sign contracts to develop and apply conservation plans that include practices such as drip irrigation, and precise land levelling as well as an enlargement and concrete lining of irrigation ditches. The project is evaluated by comparing the amount of water used on each farm before improvements are made to that used afterwards. As of the end of June, 1977, irrigation efficiency had increased to 85% on 865 acres of alfalfa; to 97% on 748 acres of cotton; and to 67% on 1,004 acres of wheat.

Overland flow and sedimentation did not increase, although no severe storms occurred during tht study. Fires of light to moderate intensities consumed most of the fresh litter and sometimes all of the fermentation layer. Mean weight of litter plus fermentation layers were significantly reduced (alpha = 0.05) from 15,800 kg/ha to 10,100 kg/ha by three annual burns. Bulk density, total pore volume, organic carbon content, and water permeability of the mineral soil were unaltered. Stems less than 5 cm in diameter at breast height were killed, but shrubs sprouted vigorously and herbaceous vegetation was not altered. Mean concentrations of both anions (PO-P and (NO3 + NO2)-N) and cations (Ca, Mg, K) in the soil leachate collected at 15-cm depth appeared to increase after burning, although the differences were small and highly variable. Significant changes (alpha = 0.05) in the concentration of both anions were measured through the growing season. Concentrations of (NO3 + NO2)-N peaked 6 weeks after the mid-April fires, which reflects increased nitrification following burning. Sodium concentrations were not affected by burning. Although it was increased by burning, nutrient loss to deep leaching appeared to be approximately equivalent to, or less than, estimated annual input from precipitation.

Since approximately 600 acres in the watershed are patented mining claims, including many worked for over a century , reclamation has focussed on attempts to minimize serious water pollution problems originating from these old mine tailing ponds and dumps. Selected for an in-depth trial was the Sheldon Mine Complex where concerted efforts were made at revegetation, landscape design, and watershed improvement. Reseeding using those species well adapted to the particular soil, climate, and topography of the site was done following (1) recontouring of the site, (2) application of crushed limestone, (3) addition of top soil at depths from 6-8 inches. The limestone provided a buffer strip between the top soil and the underlying acidic spoil material. While the treatment applied to this particular site is not feasible for the entire watershed because of costs, the alternative under consideration is the installation of limestone filtering structures along Lynx Creek to help neutralize some of the toxic metals before they reach the stream itself. In designing the trial site, primary consideration was given to aesthetics, with the final configuration made to blend in with the surrounding topographical and vegetative site characteristics. Land shaping of the spoil material contributed to water conservation and establishment of a stable vegetative cover. Proper drainage was assured by minimizing degree of slope , and decreasing sheet and rill erosion, thus enhancing revegetation success. Future plans include chemical analysis of Lynx Lake to determine changes in water quality as a result of the Sheldon Mine Reclamation project. The final product it is hoped will be a mine reclamation manual applicable to orphaned mine sites in environmentally similar locations.

The methods for harvesting the acclimated-activated sludge and the analytical methods used in the experiment are detailed. Analyses are made of the recovered activated and acclimated-activated sludges for their inorganic composition. The acclimated-activated sludge was analyzed spectrographically. Data are given for the amino acid composition in activated sludge. Acclimated-activated sludge had a protein content of 30 to 36% while activated sludge contained 28 to 32% protein. Acclimation increased ash, inorganic sulfur compounds, and protein sulfur. Free amino acids, which were not present in activated sludge, were found in the acclimated-activated sludge. Lanthionine, a component in the lime-sulfide effluent, could be used as an indicator of the presence of alkali-degraded hair protein. Toxic heavy metal contaminants were absent from the acclimated-activated sludge and because of its protein content, it might be useful as an animal feed supplement; it could also be used as a high-lime fertilizer.

Also, the cost of blanching with four different blanchers was investigated. Water blanching had the highest hydraulic waste load, but because of its low capital investment it costs significantly less than other blanching methods. The Vibratory Spiral Blancher had a higher steam efficiency than other blanchers, and when combined with a Vibratory Spiral Cooler, it generated less wastewater than the other techniques with the exception of Hot-gas Blanching. The hydrostatic steam blancher had a much higher steam efficiency than conventional steam blanchers, but its efficiency was less than that of the Vibratory Spiral Blancher or a water blancher. Because frozen vegetables are sold by weight, yield loss from air cooling is a significant economic penalty.

During the first year, peel was processed through a 20 gpm continuous flow line which consisted of acidifying the peel to pH 4.2 with food-grade hydrochloric acid, then separating the pulp from the skin with a paddle finisher. The recovered pulp was of food quality but contained large amounts of peeling-aid residues. Peeling aids are approved for peeling but not as additives to the final product. During the second year modifications of the peeling process were studied. The tomatoes were pretreated by immersion in a 150 F aqueous bath containing about 0.15% food-grade octanoic acid. Recovered pulp met USDA quality Grade A, and the octanoic acid levels were generally low (30 ppm).

Normal-depth cut kernels, deeply cut kernels, hole-sawed and screened kernels, and pressed kernels were produced and washed in a shaker washer. The kernels were blanched and air cooled. Wash water and blanching water were collected, measured, and measurements were recorded. Intact kernel mixtures provided for substantial effluent reductions over the conventionally cut kernel mixtures. Intact kernels produced by pressing had substantially greater yields and provided for the highest yield with the lowest effluent of the four experimental methods.

The estimating model is based on a universal crop production function for water which is utilized to optimize interzonal water distribution. A solution is optimum if: (1) the value of product resulting from the last unit of water applied divided by the marginal cost of water (in this case the unit cost) is the same for all zones; (2) the value of product for the last unit of irrigation is not less that its cost; (3) there can be no negative irrigation levels, i.e., the interzonal transfer of rainfall; and (4) the total amount of irrigation water applied does not exceed the quantity available. Project zones are defined by climate, soil, and crop produced. Price and climatic uncertainty are dealt with directly in the model assuming the probability distribution of the respective varible is known. The measures of economic viability available for comparing alternative system designs include: the benefit/cost ratio , internal rate of return, and net present worth. Presented is an illustrative example--a single sugar plantation occupying multiple climatic zones and operating under conditions of price and climatic uncertainty.

Concentrations of total P in rain and black spruce throughfall were inversely related to storm size. Annual precipitation nutrient inputs to the forest floor were calculated for each site. In general, nutrient contributions from snow were less than 10% of the annual nutrient input from precipitation at each site, and differences in snow nutrient input between sites were minimal. Rainfall nutrient input differed significantly between sites. Rain and snow passing through both forest canopies were enriched with nutrients except inorganic nitrogen. Total annual nutrients added to the forest floor under the black space stand averaged 1.7 times that added in the open; the annual amount added under the aspen stand averaged 5.2 times that in the open.

Although unsaturated flow predominated in the soil during fourteen moderate-size winter storms, discontinuous saturation of upslope subsoil did occur at depths of 110-150 cm after at least 30 mm of rain fell in 12 h or less. This saturation persisted les than 20 h. Very slight changes in soil water pressure head during storms effected relatively large changes in both magnitude and direction of water flux. Maximum water fluxes in the top meter of soil were 3-4.5 mm/h, and maximum flux in the subsoil was 0.5 mm/h, slightly less than the minimum flux in the soil. Between storms, the vertical component of flux at the 10-cm depth was much less than the downslope component, but the component of flux equaled the downslope component during storms. Conversely, vertical components of flux at 70- and 130-cm depths were much less than downslope components during storms, but the vertical components equaled downslope components between storms. Analysis of piezometric levels, discharge from a seep, and streamflow revealed an abrupt decrease in rate of water flux to the lower part of the slope about 10 h after the end of rainfall. This decrease corresponded with nearly complete draining of larger pores that had filled with water during storms. Subsurface flow and channel interception averaged 97 and 3% of storm flow which, in turn, averaged 38% of total storm precipitation. No overland flow was observed.

Cluster analysis provided a means of reducing 49 variables to eight dimensions or ' clusters'. On the basis of these dimensions the population was grouped into eight recreation types having similar tastes and preferences. Such traditional variables as income and education, while more quantifiable, have been found to be unreliable indicators or recreational activity. Instead, the data showed that the outdoor recreation activity of about 70% of the population of Arizona is affected mostly by tastes and preferences. They have adequate incomes and vacation times, but their recreation is determined by such factors as attitude toward killing wildlife and the general interest of the family in outdoor activities. For some 11% of the population, primarily retired people, recreation is determined mainly by their concern with age. Only 19% of the sample was considered ' elastic ', i.e., would increase their recreational activities if they had higher incomes or more vacation time. A shift in this group from one recreation type to another because of more leisure time or higher income would affect the demand structure significantly. Consideration of alternate scenarios due to this elasticity can be useful in planning. (Lynch-Wisconsin) JF - Land Economics Vol. 53, No. 1, p 43-55, February, 1977. 1 tab, 6 ref.

The watershed has a total area of 90 sq km, 74% of which is farmland, 26% is forests and plains. Fewer than one-fourth of the population of 850 have sanitary facilities connected to sewer systems; others drain the sewage into the ground. There is no industry in the watershed. Data was collected once a week for a 24 hour period April 1973-May 1974; parameters include nitrogen compounds, phosphorus compounds, oxygen demand, pH, water flow, water temperature, and precipitation. The average yearly flow is 11.1 l/s/sq km and the total nutrient discharge was 12.9 kg N/ha/yr and 0.55 kg N/ha and 0.17 kg P/ha for the watershed. The farmland is both cultivated and fertilized and one-half of it has artificial drainage. Annual fertilization in the total watershed is 90 kg N/ha and 20 kg P/ha. Farmland, forest, area, precipitation, and groundwater were considered in evaluating the discharge. Nutrient discharge excluding contribution from the population is 12.4 kg N/ha/yr and 0.18 kg P/ha/yr.

Lakes Hald, Viborg Nr., and Tjele Langsoe are eutrophic, Glenstrup in meso-eutrophic, and Viborg Sdr. is polytrophic. Ammonium release from organic nitrogen begins in early spring with increased water temperature. When the temperature reaches about 4-6.5C nitrification begins, and a maximum nitrate concentration is reached by June-July at a dissolved oxygen level of about 1.5 mg/l; nitrification ceases at this point. With a further reduction in DO to 0-0.2 mg/l, denitrification begins. When thermal stratification causes oxygen depletion the only nitrate pathways are nitrate reducation and denitrification. Nitrate reduction rates, measured by 15N technique varied from 0.06-15.35 micrograms N/liter/day, and depended on temperature and organic matter content. Denitrification rates, which are temperature-dependent, varied from 3-75 micrograms N/liter/day. Denitrification strongly affected nitrate removal in the hypolimnion. Utilization of ammonium by algae as a protein source was 4-28 times more effective than utilization of nitrate. Nutrient budgets indicated that denitrification acts as an important nitrogen sink; to some extent this process makes the lakes self-regulating with respect to nitrogen content.

Within this dynamic framework, soil conservationists, for more than four decades now, have tried to keep one objective clearly in view: To bring about improved soil and water management through a voluntary, cooperative program with conservation districts and landusers. Today, soil conservationists still find themselves confronted by change and challenge. Some suggestions are made as to how public involvement can aid in solving these problems.

Studies with waste brines simulated from dry mix formulations used to process Windsor cherries indicated that in neutralization with calcium hydroxide, even when approximately 140% of the amount theoretically required for the neutralization of bisulfite was added, some SO2 remained in the brine. This was attributed to the presence of organic acids and bisulfite which interfered with calcium sulfite precipitation. Studies on the effect of organic acids on precipitation of calcium sulfite indicated that the presence of citric and malic acids resulted in higher residual SO2 concentrations than did fumaric acid. The studies also indicated that sulfite reductions could be enhanced by oxidation with hydrogen peroxide. The proposed treatment process involves separation of the precipitated calcium sulfite and sulfate from the neutralized brine by filtration, centrifugation , or sedimentation. Washing of the sludge to remove fermentable solids is recommended to alleviate possible objectionable odors arising during storage under anaerobic conditions.

AN - 18217993; 5267174 AB - The construction of wells yielding safe, sanitary water in areas of severely folded, fractured, and creviced limestone depends on the retention of enough sediment in the transmission paths to restrict the movement of contaminants. The described research has been directed towards 2 problems-the identification of terrain and hydrologic features that indicate a lack of adequate sanitary protection of ground water in the formation, and means of improving this protection. Intermittent spring-sinks along streams or in low-lying areas indicate a reversal of ground-water flow in the area. When the water level rises above a critical level sediments that have accumulated in the formation over many yrs may be discharged in a few days, resulting in a loss of filtering ability. Ground-water levels and bacteriological contamination have been monitored on 4 wells in Washington County, Maryland, since 1973. Ground-water quality deteriorated after tropical storm Agnes washed sediments from the formation. Techniques for preventing surface contaminant entry, improving filtering ability of the formation, and providing controlled relief of hydrostatic pressure have been studied as ways of protecting ground water in the formation.

AN - 18014965; 5270406 AB - The effectiveness of a grassed waterway in decreasing 2,4-D[(2,4- dichlorophenoxy) acetic acid] content in surface runoff was investigated. Corn (Zea mays L.) plots were treated with 2,4-D (0.56 kg/ha) and runoff produced by applying simulated rain was directed through a 24.4-m-long grassed waterway. the 2,4-D concns were measured under wet and dry antecedent waterway and plot conditions Reduction in 2,4-D load in waterways results from water loss by infiltration, sediment loss, and by attachment-absorption on vegetative and organic matter. Of the simulated rainfall applied 1 day after application of 2,4-D, 50% of the water ran off the plots under dry antecedent soil conditions, and 78% ran off under wet conditions. Infiltration reduced runoff flowing down the waterway an additional 25% under dry conditions and 2% under wet conditions. Suspended sediment reduction in the waterway was 98 and 94% of the total amount moving from the plot for the dry and wet waterway conditions, respectively. The total loss (on sediment and in solution) of the applied 2,4-D from the plot in the dry and wet states was 2.5 and 10.3%, respectively. Of the 2,4- D lost from the plots and entering the 24.4-m waterway, {approx} 30% reached the end of the waterway, regardless of antecedent soil moisture. JF - J. Environ. Qual.

Therefore, a very large part of out environment is directly ' agriculture-related ' in any consideration of the discharge of pollutants. Several important Federal and State laws relate to the control or abatement of agriculture-related pollution. Existing legislation generally mandates the control or abatement of pollution (from point or nonpoint sources) or authorizes the use of public funds or other resources for such purposes. Some of these laws can be effective instruments in keeping pollutants from being discharged into surface or ground waters or into the air, but the degree to which some pollutants originating from agricultural lands and operations constitute a serious environmental hazard in waters remaining controversial. Although most of the technology exists to reduce greatly the movement of these pollutants, investments are often required which benefit the nonfarm public without economic returns to the farmer. Whether a zero discharge is either an environmentally or economically feasible alternative to more limited or selective control, is explored. However, if the public is willing to bear its reasonable share of the cost for clean air and water, the needed basic legislation already largely exists. Under it, agricultural land holders may apply program standards and use their own and available program resources to bring about effective control or abatement of pollutants.

Three available methods for disposal of the waste pumped from the vaults were rejected: spreading on the ground for biodegradation, transfer to municipal waste treatment plants, and a new treatment facility on the grounds. A soil incorporation method proved to be reliable and economical ( $2,000/yr to dispose of 57,000 1 of wastes). According to this method sewage is injected into furros 0.69 m apart and 10-20 cm deep by a tank trailer which opens the furrows, injects the sewage, and closes the furrows in one operation. Bacterial, nutrient, or viral contamination of the ground water is unlikely if the site (1) has a ground water level at least 3 m below ground level, (2) has good soil development, and (3) operates under normal precipitation conditions. The system depends on filtration by the soil above the ground water table and nutrients being used by vegetation. Preferred soil textures in decreasing order (all well-drained) are: sandy loams, fine sandy loams, loamy sands, sands, and loams. The site must be at least 180 m from the nearest residence or travel lane, preferably one-half mile. Application rate must not exceed 6.2 liters of waste per m of furrow, and the slope should not exceed 5%. Reapplication is possible after three years.

Attached to or beneath sand or gravel particles is a complex life of algae, other plants, and animals such as larvae, crayfish and fish eggs. Increased sediment load from flooded roads, agricultural land, geological weathering, construction sites, and streambank erosion has a major impact. Sediment reduces the aesthetic quality of streams, fills up pool areas, restricts flow, covers valuable cropland, and carries pollutants. In addition, there is a decrease of photosynthesis, oxygen in the water, and survival rates of invertebrates and fish eggs. Sediment inhibits the growth of valuable waterfowl food plants and, together with silt, damages gravel- and rubble-type stream bottoms. Silt and other suspensoids affect fisheries by covering the bottom of streams with a blanket of material that kills fauna, reduces available food, and covers nest and spawning grounds.

Channel flow was measured in flumes at the watershed outlet; and intensity, duration, and amount of rainfall were measured by gages on the watersheds. Over a 3-year period, 115 storms produced little overland and subsurface flow above the B-horizon. Subsurface flow over an impermeable clay layer was as much as 90% of rainfall during a calendar quarter. Thirty-six of the storms produced subsurface flow on one or both plots. For these storms, subsurface flow from the upper third of the watersheds was equivalent to 26% of the channel flow on one watershed and to 27% on the other. For 27 of the 36 storms, subsurface flow from the plots peaked sooner than channel flow. Twelve storms produced subsurface flow within 20 min of the onset of rainfall, and 15 storms produced channel flow within the same time. Subsurface flow often began shortly after rainfal began, even when there was neither saturation at the point of outflow nor high antecedent soil moisture. Interconnected channel through the soil formed by decayed roots and animal burrows are the best explanation for the quick subsurface flow responses. The similarity in timing of subsurface and channel flows indicates that subsurface flow from upper slopes can contribute significantly to storm hydrographs in forested areas where permeable surface soils overlie an impermeable stratum.

This parasite is reared on sugarcane borers in the laboratory. Frequently more than one parasite develops on a single host insect and host insects vary in size. When several parasites entered the same host some did not develop because of competition between them. This problem was more acute in young host sugarcane borers than in older sugarcane borers. The early 5th stage sugarcane borer larva was the most suitable stage for parasite development.Original Abstract: QUELQUES EFFETS DU SUPERPARASITISME DES LARVES DU BORER DE LA CANNE a SUCRE PAR LA TACHINAIRE LIXOPHAGA DIATRAEAE, EN CONDITION DE LABORATOIRE Quand des larves de Diatraea saccharalis (Borer de la canne a sucre) sont parasitees par la Tachinaire Lixophaga diatraeae, la mortalite s'accroit avec l'augmentation du nombre de parasites heberges par les larves-hotes et cela, du debut du du debut du 1er stade jusqu'au 4eme stade larvaire; cependant la mortalite est plus faible chez les larves les plus agees au moment de l'attaque du parasite. La duree du developpement larvaire des asticots de la Tachinaire est plus courte chez les larves hotes les plus agees et diminue egalement en fonction du nombre de parasites par hote; toutefois la duree du developpement nymphal n'est pas affectee par le superparasitisme. Par contre le poids des pupes du parasite decroit avec la densite du parasitisme. La taille des Tachinaires n'influence pas le choix des partenaires lors de l'accouplement, mais le nombre d'[OEligufs pondus s'accroit avec le poids des femelles. Le superparasitisme n'affecte pas la longevite du diptere parasite, mais les femelles vivent plus longtemps que les males, qu'elles soient issues d'un hote faiblement ou fortement parasite. Les asticots de Lixophaga muent deux fois a l'interieur de l'hote; elles emergent au cours du 3eme stade larvaire pour la pupaison. Une competition se manifeste entre les asticots, le taux de survie dependant du nombre de parasites par larve-hote, de la localisation des asticots sur le tronc tracheen longitudinal de l'hote, et de la promiscuite entre ces larves endoparasites.

The method followed four steps: (1) the two axes of a basin are drawn following a standard procedure; (2) for each raingage location, a station angle is determined by either measuring or calculating the angle between lines connecting the station location to the farthest ends of the two axes; (3) each station is assigned a weight (the ratio of its angle to the sum of all station angles); (4) average area precipitation is calculated as the sum of the products of corresponding station weights and measured precipitation. The method is fast, efficient, and readily computerized. (Jones-ISWS) JF - Hydrological Sciences Bulletin Vol. 21, No. 3, p 379-385, September 1976. 3 fig, 1 tab, 11 ref.

Benefits include increased vegetative growth, added irrigation water, groundwater recharge, amelioration of disturbed unproductive lands, enhanced watershed quality, and protection of natural resources. Drawbacks of land disposal of effluents are minimal. Although sewage is an ideal resource for recycling, proper application should be dictated by total ecosystem response.

The best quality groundwater, as judged by its low nitrate content and coliform bacteria density, is found in areas of relatively little agricultural (pasture and livestock) land use. The adverse effect of agricultural land use on groundwater quality is more severe in the intensely developed karst than in the less intensely developed. Rural population density and soil association variations have no readily discernible effects on ground-water quality. Nitrate concent varies seasonally and in response to rainfall, and decreases with increasing well depth. Coliform bacteria density is positively correlated with nitrate content.

Various methods of erosion control are discussed briefly, and evaluated. Waterponding is a practice developed for the reclamation of scalded country, predominantly level areas that have lost topsoil through wind and water erosion. A second erosion control method is water spreading, a means of diverting surplus runoff from ridges onto adjacent cleared, cultivated land by the use of graded banks. Another method is contour furrowing, a major advantage of which is that furrows are cheaply constructed. Pitting, another control measure, involves the digging of a series of pits 2 meters long and 1 and one-half meters apart to catch runoff. Diversion tanks , another method, have the secondary purpose of supplying water for livestock. Vegetation establishment also helps to reduce erosion. The particular advantages of these erosion control methods for the Western Division of Australia are presented.

Factors affecting the cost of no discharge systems are: soils to be irrigated, climate, topography, building location and construction, herd size, crops irrigated, and method of harvest. Typical farms were studied on each of the following: (1) Mountain subregion -- moderately shallow soils of ridges; (2) Mountain subregion -- moderately deep and deep soils of broad valleys and basin; (3) Piedmont -- firm clayey solid on felsic rocks; (4) Coastal Plains -- loamy and clayey soil of smooth uplands, and (5) Coastal Plains -- loamy and clayey soils of wer lowlands. These case studies revealed that the economic impact on the dairy farmer aries mainly with herd size and with yearly milk production. The cost of feedlot runoff control varies from 10 cents per hundred weight for large herds to 27 cents for small herds. Initital investment of controlling feedlot runoff ranges from $55-$154 per cow. Annual cost ranges from 412-$30 per cow, depending on herd size. Costs are highest for small farms. Building location and feedlot layout are the most important factors affecting cost. Nitrogen was found to govern the size of the irrigation dispoal on all 5 study farms. Fixed area for disposal is the most economical. Climate has little affect on costs, Tripling storage capacity from 1 month 's capacity to 3 months ' capacity increases annual costs by one percent, but increased flexibility of management makes the increase worthwhile.

Field projects indicate that simply built rock check dams can be effective control structures. Their construction, costs, and functional relationships are therefore emphasized.

The structures and protective measures used in Virginia are to be located in shallow waters and are designed to provide protection in storms of less than hurricane intensity. The records indicate that the rate of Virginia Shore erosion is fairly constant, approximately 2 feet per year throughout the state. The protective measures employed in Virginia have thus far consisted of groin systems, bulkheads and revetments, and vegetative systems. The three systems are often used in combination. Groins often interfere with the littoral process and starve the adjacent area, thus creating or accelerating erosion in that area. However, groins may be used where there is a sufficient supply of sand to support them. The bulkhead is the most often used structure where the littoral drift supply is not sufficient to support groins. If some vegetation exists on the beach, there is a chance that the problem can be solved with more vegetation. However, vegetation has been of the most benefit when used in conjunction with structures. (Jordan-Florida) JF - Shore and Beach Vol. 44, No. 1, p 25-30 (April, 1976).

This was substantiated by the lack of a relationship between sediment production and sediment yield. Numerous bed nickpoints indicated channel instability, despite gravel bars and log steps that are part of the slope adjustment processes. Due to differences in structural density between bars and steps, size distribution of the sediment deposits above them differs. Although only qualitative guidelines are presented, the watershed or wildlife manager should be in a position to utilize the formation of gravel bars and log steps for management goals.

In order to obtain additional water supplies, the cities of Thornton and Westminster have initiated condemnation suits against three irrigation companies to obtain their water rights. The three irrigation companies have a service area of about 40 ,000 acres--30,000 are currently irrigated. Of this land, 80 percent is class II and III, the highest classes found in Colorado. Approximately 400 farms and small tracts receive water from these companies--200 are commercial farms. Total agricultural production from the irrigated lands is about $8 million per year. Economic input-output analysis shows that irrigated agriculture contributes 561 jobs to the economy and over $4 million in net income. The cities and irrigation companies should work together to develop joint use of water rather than drying up irrigated lands for municipal water supply.

Data showed that not all sediment from forest land is related to silviculture, but in some areas, past abusive agriculture and present woodland overgrazing are the most important sources of sediment. Data also showed that forest practices acts, which contain blanket regulations, are likely to be inappropriate for some areas, insufficient for others, or sometimes unnecessary. It was concluded that control of forest sediment needs to be prescriptive and site specific in nature to meet not only water quality, but other resource needs.

Plant nutrients in the runoff water and debris during the first rainy season were analyzed. The amounts of N, P, Ca, Mg, K, and Na in the soil, litter, and plant material after burning, but before erosion occurred, were measured. In the first year, an area with 50% slopes had about 7300 kg/ha (6300 lb/ac) of material eroded from the plots on the burned sites as compared to only 210 kg/ha (187 lb/ac) on similar unburned sites. On the burned area, less debris was lost from the plots having 20% slopes than from those on steeper sites. No erosion occurred on unburned slopes with a 20% slope. The total amount of nutrients lost in debris and runoff water from the steep slopes that burned, in kg/ha (lb/ac), were: nitrogen--15.1 (13.5); phosphorus--3.4 (3.0); potassium--27 (24.1); magnesium--31.6 (28.2): calcium--67.4 (60.2); and sodium--4.6 (4.1). Nutrients lost represented less than 6% of the total nutrients found in the upper 2 cm (0.79 in) of the soil and litter layer immediately after the fire.

Gaining national concern is the erosion and sediment resulting from urban development. Predicting the erosion potential of soils is one of the first steps used by the Soil Conservation Service in planning conservation systems that control soil erosion on farmland and urban developments alike. This paper described the application of research to produce a practical field procedure for determining the erosion potential of soils. Special emphasis was given to the soil factors that influence erosion and to how soil surveys are used to predict the areas of potential erosion.

One component of the plan was to construct 852 small check dams, 24 to 30 feet in height, in key channels, using reinforced concrete cribbing. The study used single regression analysis to relate the sediment yield of treated channels, for several years before treatment, to a norm. The treated channel was then related to the same norm to determine its post treatment performance to the amount of sediment expected without treatment. A second regression used annual runoff, in place of the norm, to analyze the influence of check dams. The conclusions of the study were: (1) There is a temporary reduction in the sediment yield to the basin during the time that the check dam system fills to mature debris cones. (2) Once the system is full, the sediment yield at the basin will return to normal, or perphaps slightly higher than normal. (3) The check dam systems do not influence the rate of sedimentation relative to runoff. (4) A burned watershed, or a major flood, can induce a treated channel to unload the temporary sediment storage in the system. This can be a small volume, or a catastrophic amount, depending on how many years have elapsed in which to store sediments. (5) The check dam systems can be breached by large boulders in major floods.

Special Case: Road Erosion AN - 19174590; 7700799 AB - This paper discussed the amount of sediment trapped by a vegetative buffer that may exist below a road drainage outlet. The buffer characteristics were defined in relationship to slope percent, soil erodibility, and a soil-cover complex index called the Runoff Curve Number (RCN). A Standard Buffer was defined as a particular length of site capable of trapping 953 kilograms of sediment per year: Standard Buffer, meters = (16.16 + 17.69 Soil K + 1.34 Slope percent) x (31RCN)/(6900 - 69 RCN), where: Standard Buffer is the slope distance needed for filtering out the sediment, soil ' K ' is the soil erodibility index from the universal soil loss equation, and RCN is the Runoff Curve Number from the Soil Conservation Service Engineering Handbook. It was found that the ratio of actual buffer distance to the Standard Buffer distance times 953 kilograms equals the yearly sediment trapped. It was concluded that the relationship of Road Erosion minus Sediment Trapped has implications that can be used as a first approximation of some land use effects on water quality.

An estimated 74% of the erosion occurred on rangeland with lesser percentages on forest, urban, and crop land. It was found that erosion in localized areas can be more than 15,242 cubic meters per square kilometer per year (32 acre-feet per square mile per year). It was also learned that average annual sediment yield to reservoirs may be more than 4,334 cubic meters per square kilometer per year (9.1 acre-feet per square mile per year).

Alternative forest management recommendations were suggested for minimizing the impact of possible future debris torrents within the study area.

This treatment has been used by land managers on highly erosive soils in the Rio Puerco drainage of New Mexico to hold moisture where it falls, therby increasing plant growth and decreasing erosion. This paper reported on a study done on and near the San Luis Watersheds on the Rio Puerco drainage, 93 km (58 miles) northwest of Albuquerque, New Mexico, in the transition zone between woodland and semi-desert grassland. The area is comprised of mesas or uplands, steep rocky breaks, and alluvial grasslands. Surface runoff was still reduced 85% and erosion 31% 3 years after the soil ripping treatment. Treatment effectiveness declined after 3 to 5 years depending on amounts and intensities of summer thunderstorms. Opening old rips that were sealed over with sediment was as effective in controlling runoff as ripping between old rips. Reripping by either method reduced runoff by two-thirds compared with untreated check plots. Ripping caused a favorable shift in forage production from galleta to alkali sacaton. It was learned that ripping effects on runoff are short-lived, but forage production patterns may persist for 10 years; ripping must be done carefully to avoid subterranean channel formation (erosion by soil piping).

These techniques were developed and evaluated through a low elevation color infrared photography flight and concurrent water quality sampling conducted on 164 km (100 miles) of stream over the West Fork of the Madison River in southwestern Montana. The concentrations and sources of sediment produced during peak snowmelt runoff were determined by photo densitometric analysis coupled with specifically located ground control stations. Excellent correlations were established by regression analysis of the ground truth variables including stream width to discharge and suspended sediment to turbidity. Photo density was correlated with suspended sediment and turbidity. Both produced strong correlations which were significant at the 99% confidence level. These correlations made it possible to determine reliable estimates of sediment concentrations from the aerial photography where stream measurements were not obtained. The photographic analysis indicated that the majority of the suspended sediment sources during the snowmelt runoff event were derived primarily from channel erosion. Additional interpretations which can be derived from photo analysis were also presented and discussed.

Numerous publications, people, and agencies seek to increase their use by extolling their merits. Virtually nowhere, however, is the idea of excavated--rather than impounded--sediment traps even mentioned, let alone recommended as a superior method of accomplishing the sediment control task. A decade of experience on large earth moving jobs in the rugged Missouri Ozarks has shown that excavated sediment traps are incomparably superior to small detention dams in terms of cost, industry acceptance, and sediment trap efficiency. This ' how to ' article was a working man 's guide to excavated sediment trap design and construction.

Specialists are working to minimize the environmental damage resulting from road construction and logging impacts. Problems result when entry is made into steep granitic terrane with high rainfall where road construction and logging is planned. The damage is largely due to liquefaction type failures which produce greatly accelerated mass wasting as a result of debris landslides and flows. This geotechnical scheme was a unique plan for forest land management which produces a quantitative program for an environmentally safe operation and will yield an economically feasible project. The format of the scheme was: (1) Select a granitic area with stability problems, prepare detailed topographic map and obtain color and color infrared photography. (2) Hydrologic monitoring. (3) Engineering geologic study: mapping, drilling, sampling, geophysical surveys, field testing for stability parameters. (4) Soil engineering: lab and model test representative samples and compute stability parameters. (5) Correlate field properties with lab and model tests. (6) Prepare stability unit map. (7) Develop logging and road construction project using stability map and road design data.

Twenty-three bottom sediment samples were collected through the ice along eight ranges in the lake. Two ranges were augered on the flood plain of Trout Creek above the impoundment. The samples were first described in the field, and then selected portions of core profiles were analyzed for physical and chemical properties. The volume and density of a 10.5-year accumulation of sediment in the reservoir were determined. The sediment survey indicated an average annual sediment yield in 10.5 years of 3.45 metric tons/ha (1.54 tons/acre) as compared with a predicted average annual yield of 1.88 metric tons/ha (0.84 tons/acre) in 1960 prior to dam construction and 1.59 metric tons/ha (0.71 tons/acre) in 1974. The watershed was predominantly cropland and pasture. Land use and land treatment were compared prior to dam construction and in 1974. Comparisons were made between predicted watershed sediment yield and the measured sediment in the reservoir. This study is a basis for future land use, land treatment, and sediment surveys at 5-year intervals.

AN - 733485681; 16659441 AB - The effects of salinity on corn plants (Zea mays L.) are influenced by the concentration of nutrient orthophosphate. Salinity (-2 bars each of NaCl and CaCl(2)) was more injurious in combination with a high concentration of orthophosphate (2 mm) (that gave optimum yields in the absence of salinity) than it was with a lower concentration (0.1 mm). With 2 mm orthophosphate, salinity seemed to damage the plant mechanisms that normally regulate the internal concentration of orthophosphate resulting in excessive accumulation and P toxicity. On the other hand, with 0.1 mm orthophosphate, salinity decreased orthophosphate concentration in mature leaves. This effect was paralleled by decreases in the concentration of adenosine 5'-triphosphate and in the energy charge of the adenylate system, indicating an orthophosphate deficit. Even so, plants survived salinity better under these conditions than in the presence of 2 mm orthophosphate. The data indicated that salinity affected the phosphorylated state of the adenine nucleotides only indirectly through its effect on the concentration of orthophosphate in the cells.Salinity, especially in the presence of 2 mm orthophosphate, resulted in an increase in the concentrations of sugar phosphates in mature photosynthesizing leaves, suggesting that translocation rather than photosynthesis was a limiting process. Decreased translocation could be a secondary effect of decreased growth. However, a decreased translocation rate could cause decreased growth by limiting the supply of essential metabolites reaching growing tissues.

The algorithm can be coded as subroutines of a computer model that requires solar radiation as a variable. The required inputs are Julian dates and the latitude, inclination, and aspect of the slope. In addition to computing potential solar radiation, the routine provides estimates of actual radiation on any slope on the basis of measured solar radiation for a nearby horizontal surface that has the same cloud cover.

It was planted with water-tolerant grass. Effluent was applied using a sprinkler system. Operating during the growing season, peat bed effluent should be produced that will meet most, if not all, discharge requirements. Such effluent should have no fecal coliform, little total coliform, BOD5 and suspended solids of approximately 5 mg/l, and nitrogen content of less than 10 mg/l. A system of this type could be used to disinfect and improve the quality of effluent all year if there are no stringent requirements on phosphorus and nitrogen. A peat bed should be designed to handle not more than 0.625 cm/hr and 5-15 cm/day of secondary or primary effluent. A bed life of close to 10 years is expected. After three years, treatment efficiency has not deteriorated, but has increased.

Some of the habitat area has a partial water supply, some a full supply, but much of it has very little water. Agricultural drainage could provide a full water supply for up to 127,170 ha (314,000 acres) of wildlife habitat by the year 2000. The impact of such usage would be greatly beneficial both to wildlife habitat development and to irrigated cropland. Agricultural drainage can provide a firm water supply for wildlife and the wildlife use will allow the development of on-farm drainage systems to maintain land productivity. Further, such a short-term plan would be easily adaptable and in fact complementary to a long term plan for a master drainage system to be implemented at a later date.

U.S. Department of Agriculture agencies conducting programs directly concerned with management of agricultural and forest lands must bear responsibility for maintaining the quality and availability of water resources in the face of these impacts. Of particular concern are pollutants resulting from fuel extraction and diversion of water from agricultural to energy uses.

ESPECIALLY VULNERABLE ARE STORMFLOW SOURCE AREAS AND SITES SUBJECT TO RAPID SUBSURFACE FLOWS. SKID TRAILS ARE THE PRIMARY SOURCE OF SEDIMENT FROM LOGGING; BUT INCREASED WATER YIELDS AFTER COVER REMOVAL EXPAND SOURCE AREAS, INCREASE OVERLAND FLOWS, AND INITIATE SHEET AND RILL EROSION. LITTER DECOMPOSITION AFTER CLEARCUTTING EXPOSES MINERAL SOIL AND PROMOTES SURFACE SEALING WHICH REDUCES INFILTRATION AND INCREASES OVERLAND FLOW AND SEDIMENT YIELD. INCREASED FLOW THROUGH MACROCHANNELS MAY ACCELERATE EROSION WITHIN THE OPENINGS AND INCREASE SEDIMENT DELIVERY TO STREAMS EVEN IN THE ABSENCE OF SURFACE EROSION. INTENSIVE SITE PREPARATION OFTEN REMOVES ALL VEGETATION AND MOST OF THE FOREST FLOOR, COMPACTS THE SOIL SURFACE, AND SEALS MACROCHANNEL OPENINGS, THEREBY ALTERING THE NORMAL FLOW PROCESSES. SEWAGE EFFLUENT DISPOSED ON SOURCE AREAS AND SITES WITH RAPID SUBSURFACE FLOWS MAY PASS UNALTERED THROUGH MACROCHANNELS OR OVERLAND TO STREAM CHANNELS, POSING SERIOUS POLLUTION PROBLEMS. THE KEY TO MINIMIZING HYDROLOGIC IMPACTS OF FOREST MANAGEMENT IS TO CATEGORIZE EACH SITE ACCORDING TO ITS SUITABILITY FOR SPECIFIC TREATMENTS, RECOGNIZING THE VARIABLE RATHER THAN FIXED NATURE OF STORMFLOW SOURCE AREAS.

A flow chart is included which shows the steps followed in selecting the concept of groundwater flow which best fits measured hydrogeologic conditions. Both noneffluent and effluent stream conditions are evaluated using the method. Residual maps of hydraulic conductivity are used to show how modeled hydraulic conductivity may be as much as 300 times that expected when the wrong concept is used. Flow nets of modeled and measured data downstream from a flood-water-retarding structure are developed using the selected hydrogeologic conditions. Fitting hydraulic conductivity data results in a distribution of ground-water flow paths which better represent actual flow conditions. The method provides a unique means of calibrating a model in a pilot test area and applying it to geologically similar nearby watersheds. It is also useful for checking paths of subsurface flow where flow distribution is important as it is in the movement of chemical pollutants or nutrients from a source of recharge, such as a watershed impoundment, to downstream waters.

AN - 17996759; 5265320 AB - A. philoxeroides, an aquatic amaranth introduced into the United States form sough America around 1900, was recognized as a threat to the aquatic ecosystem as early as 1901. It has been classed as a weed because of its competitive advantage over native flora. A 1963 survey found the weed commonly throughout the southeastern United States. Alligatorweed was estimated to infest 65,700 ha in the states of North and South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, and Texas. Biological control of alligatorweed was begun in 1960 with surveys in South America for natural enemies. Research in South America by US Department of Agriculture entomologists resulted in the introductions of 3 spp of insects into the United States for control of alligatorweed. Agasicles hygrophila (Cloeoptera: Chrysomelidae) was first introduced in 1964, Amynothrips andersoni (Thysanoptera: Phlaeothripidae) in 1967, and Vogtia malloi (Lepidoptera: Pyralidae: Phycitinae) in 1971. These insects are now providing substantial control of alligatorweed over the entire range where the weed occurred as an aquatic plant problem. It is the authors' contention that alligatorweed will cease to be an important aquatic weed and only rarely will be found in pure stands in any significant proportions in the United States of America.

AN - 17991087; 5255243 AB - N. bruchi strongly preferred waterhyacinth, Eichhornia crassipes in a variety of Lab tests. Host specificity was greatest in larval feeding and population, slightly less in ovipositional preference, and least in adult feeding preference and survival. Adults fed and oviposited a small amount on other members of the fam Pontederiaceae, prefering Reussia rotundifolia, Eichhornia azurea, and Pontederia lanceolata in that order, and lesser amounts on the closely related fam Commelinaceae and a few other plants that grow in the same habitat with waterhyacinth. However, larval feeding and pupation restricted N. bruchi to completing its entire life cycle on E. crassipes and probably rarely on Reussia and E. azurea, which are either noxious weeds themselves or do not occur in the US. The small amount of feeding by adults poses no threat of damage to other plants. N. bruchi is sufficiently host specific to introduce into the US to control waterhyacinth without damage to economic plants or native vegetation. JF - Ann. Entomol. Soc. Am.

AN - 17986654; 5254939 AB - N. bruchi oviposited in the petioles of waterhyacinth, Eichhornia crassipes, and the eggs hatched in 7.6 days. The larvae tunnelled inside the petioles and crown of the plant, and completed their growth in {approx} 32 days; they pupated underwater attached to a living root of the floating plant, from which they probably obtained O Sub(2). Prepupae required 7 days and pupae {approx} 23 days for development. female N. bruchi preferred the older bulbous leaves and N. echhorniae preferred the young central leaves for oviposition. Maximum feeding and oviposition of both spp occurred at 30{degree}C. Adult N. bruchi ate a maximum of 75 mm Super(2) of waterhyacinth leaves/day, and N. eichhorniae ate 86 mm Super(2) /day; female ate 2.8 times as much as male. N. bruchi laid a maximum of 8.5 eggs/female/day, and N. eichhorniae laid 7.3 eggs/female /day. At cooler temps, N. bruchi fed and oviposited slightly more than N.eichhorniae. The intrinsic rate of increase of N. bruchi held at optimum lab conditions was calculated to be 0.05675, and generation time was 96 days; the population would double in 12.2 days. Because N. bruchi laid more eggs and its larvae developed faster, it killed waterhyacinth plants in the lab sooner than did N. eichhorniae. JF - Ann. Entomol. Soc. Am.

Released moths either irradiated with 20 Krad or unirradiated, were found predominantly within a few hundred meters of the release points. Prior to formation of a plant canopy, daytime-resting places of moths were soil crevices at the bases of the plants. Later, when a protective plant canopy had formed, about half of the moths took resting places in the lower canopy, many in withered blooms. Little mating occurred between released males and native females, probably due to the great preponderance of native males in the test area. The technique of autoradiography of native females to determine mating with released labeled males was simple and effective.Original Abstract: AUSBREITUNG UND PAARUNG IM FELD BEI MAeNNCHEN DES ROTEN BAUMWOLLKAPSELWURMS, PECTINOPHORA GOSSYPIELLA, NACH MARKIERUNG MIT32P Im Labor gezogene Maennchen von P. gossypiella wurden mit 32P gefuettert, um Ausbreitung und Paarung im Baumwollfeld zu studieren. Freigelassene Falter, teils bestrahlt mit 20 Krad, teils unbestrahlt, wurden vorwiegend innerhalb von 100 m von der Freilassungsstelle gefunden. Vor Bildung eines geschlossenen Bestandes waren die Tagesruheplaetze der Falter Bodenspalten an der Basis der Pflanzen. Spaeter, wenn ein schuetzender, dichter Pflanzenbestand gebildet war, hatten die Falter ihre Ruheplaetze etwa zur Haelfte in dem unteren Bereich des Pflanzenbestandes, davon viele in verwelkten Blueten. Zwischen freigelassenen Maennchen und Freilandweibchen kam es nur zu wenig Paarungen, wahrscheinlich wegen des zahlenmaessigen Uebergewichts der Freilandmaennchen im Gebiet.

THIS HYDROLOGIC POTENTIAL OF FOREST SITES CAN BE INTERPRETED FROM ANALYSIS OF WATERSHED MODELS THAT EXPRESS SITE CHARACTERISTICS AS VARIABLES. SIX STREAMFLOW PARAMETERS EXPRESSING ANNUAL AND 10-YEAR FREQUENCY CHARACTERISTICS WERE RELATED TO 21 TO 29 WATERSHED VARIABLES. THE DATA FOR ANALYSIS WERE DRAWN FROM 109 WATERSHEDS IN NORTHERN CALIFORNIA, COVERING THE PERIOD 1881 TO 1971. THESE STREAMFLOW RECORDS WERE ADJUSTED TO THE 81-YEAR RECORD BY USING ONE OF 10 KEY STATIONS. THE 29 VARIABLE, 109 CATCHMENT, DATA MATRIX WAS TESTED FOR INDEPENDENCE BY FACTOR ANALYSIS. TO REDUCE THE CORRELATION BETWEEN SOME VARIABLES, 16 WATERSHEDS WERE DROPPED FROM ANALYSIS. THEN THE QUANTITATIVE RELATIONS WERE DETERMINED BY REGRESSION USING REDUCED RANK PRINCIPAL COMPONENT ANALYSIS. EXPLAINED VARIANCE RANGED FROM 72 TO 87 PERCENT FOR THE ANNUAL AND FLOOD STREAMFLOW PARAMETERS, BUT ONLY 46 TO 48 PERCENT FOR THE TWO LOW-FLOW PARAMETERS. THE QUANTITATIVE RESULTS ARE GIVEN BY THE 185 REGRESSION COEFFICIENTS OBTAINED. WIDE DIFFERENCES IN MANAGEMENT PROBLEMS AND POTENTIALS WERE INDICATED. FOR EXAMPLE, FOR THE NINE GEOLOGIC TYPES TESTED, ANNUAL STREAMFLOW POTENTIALS WERE AS LITTLE AS 30 PERCENT OF AVERAGE TO MORE THAN THREE TIMES AVERAGE. LOW FLOWS WERE EVEN MORE VARIABLE, WITH THE GRANITIC ROCKS YIELDING LOW FLOWS ONLY 1 TO 3 PERCENT AS HIGH AS THE BASIC AND ULTRA BASIC ROCK TYPES (BASALT AND SERPENTINE). SUCH DIFFERENCES IMPLY DIFFERENT PROBLEMS OF MANAGEMENT FOR WATER SUPPLY.

The 12,000-acre Black Creek watershed discharges sediment and nutrients into the Maumee River, a Lake Erie tributary. The five-year project, begun in 1972, was designed to analyze each of 200 farms over five acres and to apply all needed land treatments to reduce erosion and soil loss. Planning goals included: (1) erosion and sedimentation control; (2) balanced crop rotation; (3) planned fertility; (4) manged water disposal; (5) reorganized field layout; (6) improved livestock programs; (7) farm ponds; and (8) improved land value and beauty. Aerial photographs and individualized soil maps provided basic planning data. On each farm soils were classified by degree of hazard. Treatment alternatives for cropland with erosion hazard were formulated through use of the Universal Soil Loss Equation (USLE), A=RKLSCP, which is described in full with examples in this paper. Management and mechanical practices included crop rotation, residue use, minimum tillage, contouring , and strip cropping; mechanical methods included diversion, terracing, and grassed waterways. If landowners were agreeable to the plans presented, a contract was drawn up between the landowner and the Allen County Soil and Water Conservation District, which provided for cost-sharing and technical assistance.

Natural or constructed, they are shaped to required dimensions and vegetated for safe disposal of runoff, and are employed when rainfall exceeds the ability of the soil to absorb or store the moisture. Use of grassed waterways enables removal of surplus water without undue erosion. The following procedures are advised: (1) construction of the water before any other channels that will discharge it; (2) establishment of vegetitive cover by means of mulching, sodding, and irrigation; (3) conveying prolonged flow in a subsurface drainage system; (4) use of stable natural waterways where possible; and (5) maintenance of cover through mowing and fertilization; parabolic design, the shape most often found in nature, is the most satisfactory, although trapezoidal and V-shaped designs are also used. Small flows are least likely to meander in a parabolic waterway. The waterway should be located in a well-vegetated natural draw, which provides the flattest grade, most stable channel, adequate capacity, soil and moisture most favorable to vegetation, and sufficient depth for outletting diversions, terraces, and rows at grade. A tile system providing drainage and protecting the center of the waterway should be included where prolonged low flows or wet conditions prevail.

ALUMINUM IS THE DOMINANT CATION AND THE EXCHANGE PROPERTIES OF THE BH HORIZONS ARE DOMINATED BY A1 AND ORGANIC CARBON. ONE TO TWO GRAMS OF TOTAL CA, MG, AND NA/SQ M PER YR ARE BEING ADDED TO THESE SOILS BY RAINFALL AND RECYCLING. FROM 3 TO 40 G OF CARBON/SQ M PER YR IS AVAILABLE TO MOVE INTO THE SOLUTION BELOW 10 CM. THIS IS ENOUGH CARBON TO DEVELOP A BH HORIZON 7 M THICK IN LESS THAN 30,000 YEARS. THE MECHANISM THAT IMMOBILIZES THE CARBON TO FORM THE BH HORIZON IS OPEN TO QUESTION. IT WAS POSTULATED THAT BASES, PH CHANGES, OR OTHER ASPECTS OF THE CHEMICAL ENVIRONMENT MAY HAVE IMMOBILIZED THE CARBON INITIALLY, BUT THESE CAUSES HAVE SUBSEQUENTLY BEEN REMOVED OR CHANGED THROUGH LEACHING. ANOTHER ALTERNA TIVE IS ORGANO-MINERAL BONDING SUCH AS WITH SILICA ON QUARTZ SURFACES THAT MAY BE THE MAJOR FACTOR IN THE IMMOBILIZATION OF CARBON.

NOT UNTIL THE SECOND YEAR AFTER FENCING DID SOILS SHOW SIGNIFICANT INCREASES IN MACROPORE VOLUME. INFILTRATION CAPACITIES ALSO INCREASED AND SUMMER RUNOFF DECREASED. ONE SOIL WAS A MEDIUM-TEXTURED SILT LOAM AND THE OTHER WAS A SANDY LOAM. AT A THIRD SITE WHERE SOIL WAS MEDIUM-TEXTURED BUT HIGH IN ORGANIC MATTER CONTENT AND WITH A LOW BULK DENSITY, SOIL RESPONSES WERE UNCERTAIN. INFILTRATION INCREASES STARTED TO APPEAR AT ABOUT THE SAME TIME AS IMPROVEMENTS IN SOIL STRUCTURE. PROTECTION FROM GRAZING AND TRAMPLING RESULTED IN LESS SUMMER STORM RUNOFF IN THE FIRST GROWING SEASON AND ALSO IN EACH OF THE FOLLOWING THREE YEARS. AFTER THE FIRST WINTER, SNOWMELT RUNOFF FAR EXCEEDED SUMMER STORM RUNOFF AT ALL THREE SITES. OVERALL RESULTS CLEARLY INDICATED THAT MORE THAN ONE SEASON PROTECTION WAS NECESSARY FOR SIGNIFICANT SOIL RECOVERY, AND DEGREE OF RECOVERY CONTINUED UP TO AT LEAST FOUR YEARS, THE DURATION OF THIS STUDY.

Both N and P inflow/outflow levels were relatively constant throughout the study. Levels of nitrite-N, nitrate-N, ammonium-N, and organic-N were generally higher in the outflow than the inflow, but were typically within recommended water quality limits. Similarly, average total and soluble P concentrations increased in the raceways, doubling from inflow to outflow. Nevertheless, the increased N and P levels did not result in serious problems due to algae or other aquatic growths. Moreover, the health and growth of the catfish remained good. Present raceway management and catfish production practices seem to pose no particular water quality problem.

The simulation was tested by comparing drainage to measured streamflow. In a year of unusually high precipitation the simulated annual drainage was within 1.5% of measured streamflow. Simulations were also performed by using the same 2 years of meteorologic data, but vegetation parameters were changed to represent a young white pine plantation and a regrowing hardwood forest 1 year after clear-cutting. The model estimated that drainage for an average rainfall year was reduced 20 cm by a 16-year-old white pine plantation and increased 36 cm by clear-cutting. These results were comparable to changes of -20 and +38 cm observed in watershed experiments at Coweeta Hydrologic Laboratory. Simulated evapotranspiration during the summer was nearly identical for hardwood and pine forests, while winter and early spring water loss was greater for pine. Simulation suggests that the greater evapotranspiration by pine was due to increased interception in all seasons and increased transpiration in the dormant season. For the clear-cut area, simulated evapotranspiration was considerably less than it was for the pine or hardwood forest and thus caused simulated soil moisture contents to be greater during the summer season.

RESINOSA), WHITE SPRUCE (PICEA GLAUCA), AND EUROPEAN LARCH (LARIX DECIDUA) WERE ESTABLISHED ON THREE SITES IN SOUTHWESTERN WISCONSIN AND THE CHANGES IN LETTER WEIGHT, SOIL BULK DENSITY, SOIL NITROGEN AND ORGANIC CARBON CONTENTS, SOIL WATER DEPLETION, AND SNOWPACK ACCUMULATION WERE EVALUATED OVER 14 YEARS OF GROWTH. THE SITES INCLUDED AN UPPER NORTHERN SLOPE OF 10 PERCENT, A LOWER NORTH SLOPE OF 25 PERCENT, AND A MIDDLE SOUTH SLOPE OF 25 PERCENT. THE GREATER AMOUNTS OF LITTER THAT BUILT UP UNDER LARCH WOULD SEEM TO MAKE IT A PREFERRED SPECIES FOR WATERSHED MANAGEMENT PLANTING; HOWEVER, THE ADDITIONAL LITTER MAY HAVE NO VALUE IN PREVENTING RAINFALL RUNOFF. IT MAY REDUCE SOIL FREEZING, WHICH COULD REDUCE SNOWMELT RUNOFF. THE PLANTATIONS ARE NOT YET OLD ENOUGH TO HAVE REDUCED SOIL BULK DENSITY. BY THE 10TH YEAR, THE PINE AND LARCH PLANTINGS WERE USING SUBSTANTIALLY MORE WATER FROM THE TOP METER OF SOIL THAN THE UNPLANTED CONTROL, AND A LITTLE MORE THAN A NATURAL HARDWOOD FOREST. THE ADDITIONAL WATER DEPLETED BY THE TREES CAN REDUCE FLOOD RUNOFF POTENTIAL FROM SUMMER STORMS, BUT ON THE OTHER HAND, THIS MAY REDUCE THE CONTRIBUTION TO GROUNDWATER, SPRINGFLOW, OR STREAM BASE FLOW, WHICH WOULD HAVE A NEGATIVE EFFECT OF WATER PRODUCTION.

THEY ARE NOT 'SOIL' IN A PEDOLOGIC SENSE, NOR ARE THEY GEOLOGICALLY THE SAME AS THE ROCK FORMATIONS FROM WHICH THEY WERE DERIVED. THEIR UNIQUE PROPERTIES SOMETIMES POSE PROBLEMS IN REVEGETATION ATTEMPTS. AS A FIRST STEP IN UNDERSTANDING SPOILS, SAMPLES FROM THE AMAX COAL COMPANY IN CAMPBELL COUNTY, WYOMING WERE ANALYZED BY STANDARD AGRICULTURAL SOILS ANALYSIS PROCEDURES. THE SPOILS WERE OVERBURDEN FROM THE ROLAND AND SMITH COAL BEDS OF THE FORT UNION FORMATION. COAL FROM THIS FORMATION REPRESENTS THE GREATEST STRIPPABLE DEPOSIT IN WYOMING. ALTHOUGH SLIGHTLY MORE SALINE THAN THE SURROUNDING NATURAL SOILS, THE SPOIL SALINITY IS NOT ENOUGH TO SEVERELY LIMIT PLANT GROWTH OR SURVIVAL. THE GENERAL NUTRIENT STATUS OF THE SPOILS IS LOW FOR IDEAL PLANT GROWTH, BUT THE GENERALLY LOAMY TEXTURE IS FAVORABLE. FURTHERMORE, THE HOMOGENEITY OF PHYSICAL PROPERTIES AND DRESSED SPOIL DEPTH PROVIDE A MOISTURE RESERVOIR CAPACITY CONSISTENT WITH CAPACITIES OF NATURAL SOILS.

Two basic principles of National Forest Management issued in the 1950 's are still applicable: protection of the watershed by stabilizing the soil and thereby preserving and enhancing water quality; and management of the area to improve water yields. Multiple use management accounts for timber production, recreation, grazing and wildlife as priorities equal to water yield. Watershed management studies and their benefits are briefly discussed; in Arizona alone, $10 million in public and private funds has been spent on such projects. Problems described include the meeting of water quality standards, the cost of increasing water yields, and the impact of chemical herbicide restrictions on water yield improvement programs. Future watershed management studies and programs are discussed. (See also W77-02104) (Jahns-Arizona) JF - 19th Annual Arizona Watershed Symposium Proceedings Report No. 7, p 35-36, September 1975.

The relative stability of these ecosystems was defined in terms of resistance and resilence, and the impact of alternative levels of tree utilization on subsequent productivity after several rotations was evaluated. Results establish the relevance of ecosystem relative stability to practical mangement problems.

Studies were undertaken to learn whether modification of vegetation could produce more water in the Salt-Verde River Basin; ponderosa pine and pinyon-juniper vegetation in the Beaver Creek watershed account for 60% of the total Basin runoff. Woods Canyon and a control site are described and the objectives of the experiment outlined along with a land use plan being formulated. Major management alternatives considered for the pine lands in the Woods Planning Unit are discussed. One alternative emphasizes primary wood production on an even flow basis over the entire area. The second alternative stresses equally the production of timber and the maintenance and improvement of big game habitat. The third involves retaining natural conditions and esthetics while preserving commodity production on some of the more productive soils. The fourth alternative stresses water yield and livestock forage. Potential effects on water yield for each approach are analyzed; alternative four promises the greatest yield of both forage and water.

The amount of land meeting criteria for active management must be ascertained. Other considerations include environmental effects, potentials for increasing water yield, forage production and recreational opportunities, and methods for reducing fire suppression costs in chaparral areas. Conversion of 21% of the chaparral could increase Arizona 's yearly water supply by an average of 150,000 acre feet (2% of the total). Other possible effects of conversion are described, including increased erosion. Chaparral can be controlled or eliminated mechanically by rootplowing, prescribed burning, and with herbicides; the costs and effectiveness of each method and some management alternatives are analyzed. Management by protection is still the main approach but is inadequate; one problem is the lack of financing for large-scale conversion and maintenance operations. Another problem involves finding an effective and environmentally acceptable chemical for initial treatment and maintenance on chaparral watersheds. More intensive management in the future is likely, and continued research will be necessary. Some possible directions of research are discussed.

Analysis of population growth in areas adjacent to cities, as compared to further outlying areas, finds that more Ru areas are growing faster. Explanation for this upsurge in Ru migration is made in terms of a "decentralization trend" of manufacturing, retiree movements, & the growth of "Coll towns." Exceptions to this are areas where agriculture is the predominant trade & areas of high black population in the South. Other reasons for this growth in Ru populations include the declining birth rate in cities & the new appeal of country living. C. Strong.

Knowledge of their stage of development tells about future watershed behavior. This is critical for watershed management because man may enhance or hinder future natural processes. Dynamic characteristics of two perennial and two ephemeral mountain streams revealed that the former are in a state of dynamic equilibrium, while the latter are still working toward its attainment. Bed characteristics indicated that both aim at adjustment to slope by formation of rock and log bars. Thus, the surrounding forest plays an active role in stream hydraulics.

FOREST ROADS THAT CROSSED STEEPLY INCLINED STREAM CHANNELS CAUSED MUCH GREATER LEVELS OF SEDIMENTATION THAN ROADS ON RIDGE TOPS. MORE TIME WAS REQUIRED FOR SOILS TO STABILIZE FROM CLEARCUTTING AND FOREST ROADS IN THE STEEPER COUNTRY. IN VERY STEEP TOPOGRAPHY, WHERE SOIL STRENGTH IS NEARLY IN BALANCE WITH THE POTENTIAL FOR DOWNSLIDING, THE LARGEST SEDIMENTATION INCREASES ARE EXPECTED AS A RESULT OF FREQUENT MASS EROSION EVENTS. NUTRIENTS ARE LOST FOLLOWING CLEARCUTTING, BUT THE LOSS DECREASES RAPIDLY WITH REVEGETATION. MAXIMUM NO3-N CONCENTRATION INCREASES IN STREAMS HAVE REMAINED WELL BELOW TOXIC LEVELS. NUTRIENT LOSSES BY SOIL EROSION ARE UNDOUBTEDLY OF GREATER IMPORTANCE ON STEEPER SLOPES. FOREST FERTILIZATION-WATER QUALITY STUDIES INDICATE THAT N CONCENTRATION IN STREAMS DOES NOT INCREASE TO LEVELS EXCEEDING PUBLISHED STANDARDS. TOTAL LOSS OF APPLIED NUTRIENT IS SMALL AND SHOULD NOT HAVE ANY MEASURABLE IMPACT ON EUTROPHICATION IN DOWNSTREAM IMPOUNDMENTS. THE DRIFT OR DIRECT APPLICATION OF SPRAY MATERIALS TO SURFACE WATERS IS THE PRINCIPAL ROUTE OF HERBICIDE ENTRY TO STREAMS. OVERLAND FLOW AND LEACHING OF HERBICIDE ARE RELATIVELY UNIMPORTANT FACTORS IN FOREST STREAM POLLUTION. CAREFULLY CONTROLLED HERBICIDE APPLICATIONS ARE NOT EXPECTED TO HAVE A SIGNIFICANT IMPACT ON FOREST STREAM QUALITY.

An improvement in forecasting is an improvement in management. Various mapping techniques were tried and evaluated. There were many problems encountered such as distinguishing clouds from snow and snow under trees. A partial solution to some of the problems involves ground reconnaissance and low air flights. Some problems go unanswered. Snow areas, cloud cover, and total areas were planimetered after transferring imagery by use of zoom transfer scope. The determinations were then compared to areas determined by use of a density slicer. Considerable adjustment is required for the two values to compare. NOAA pictures also were utilized in the evaluation. Forest cover is one of the parameters used in the modeling process. The determination of the percentage is being explored.

AVERAGE SUSPENDED SEDIMENT CONTENT OF WATER DURING THE 1974-75 WINTER WAS 6 PPM AND RANGED FROM 1 TO 28 PPM. SUSPENDED SEDIMENT LEVELS INCREASED SHARPLY AS SNOWMELT RUNOFF BEGAN, PEAKED AT ABOUT THE SAME TIME AS MAXIMUM RUNOFF, BUT THEN FELL MUCH FASTER THAN STREAMFLOW RECESSION. SUSPENDED SEDIMENT EXCEEDED 100 PPM ON 13 DAYS DURING SNOWMELT RUNOFF IN 1974 AND HAD A MAXIMUM VALUE OF 399 PPM. SUSPENDED SEDIMENT CONTENT EXHIBITED A DIURNAL FLUCTUATION SIMILAR TO THE DIURNAL FLUCTUATION IN STREAMFLOW VOLUME. SEDIMENT LEVELS GRADUALLY DECLINED THROUGH THE 1974 SUMMER PERIOD FROM ABOUT 20 PPM IN LATE JUNE TO LESS THAN 10 PPM BY OCTOBER. BOTH SUSPENDED MOVEMENT AND RUNOFF RATES HAVE BEEN GREATEST DURING OVERSNOW FLOW, A UNIQUE HYDROLOGIC PHENOMENON. THE SUSPENDED SEDIMENT CONCENTRATION REACHED 862 PPM AT ONE WATERSHED DURING OVERSNOW FLOW IN COMPARISON TO A USUAL LEVEL LESS THAN 20 PPM DURING SNOWMELT RUNOFF. ANNUAL BEDLOAD DEPOSITION RANGED FROM 0.09 TO 3.88 CU M PER SQ KM AND WAS HIGHEST IN YEARS WITH OVERSNOW FLOW.

PROJECT OBJECTIVES INCLUDE THE STUDY AND DEMONSTRATION OF SURFACE MINE REHABILITATION TECHNIQUES TO ACHIEVE ACID DRAINAGE ABATEMENT, REVEGETATION, AND IMPROVED VISUAL IMPACTS IN A HIGH RECREATION USE AREA. HYDROLOGIC ANALYSES OF FLOW PATTERNS AND QUALITY OF SURFACE, NEAR SURFACE, AND GROUND WATER ARE BEING EMPHASIZED BECAUSE REHABILITATION MAY INCLUDE HYDROLOGIC ISOLATION OF THE SPOIL MATERIALS. POTENTIAL SURFACE TREATMENTS ARE BEING TESTED ON LYSIMETERS CONTAINING SPOIL MATERIAL. RELATED RESEARCH ACTIVITIES INCLUDE STUDIES OF PLANT SPECIES ADAPTABILITY, REVEGETATION TECHNIQUES, PLANT-SOIL-WATER RELATIONS, MICROCLIMATIC MEASUREMENT, AND THE PHOTOSYNTHETIC EFFICIENCY OF NATIVE ALPINE PLANTS. DATA COLLECTED DURING THE 1974-75 FIELD SEASONS WILL BE EVALUATED AND RECOMMENDATIONS FORMULATED FOR REHABILITATING THE SITES.

RESULTS INDICATE THAT WATER YIELD IS NOT IMPROVED BY MECHANICAL METHODS OF PINYON-JUNIPER REMOVAL BUT CAN BE IMPROVED BY HERBICIDE REMOVAL OF MODERATELY DENSE TO DENSE PINYON-JUNIPER STANDS. HERBAGE YIELDS INCREASE AFTER VIRTUALLY ALL PINYON-JUNIPER TREATMENTS, BUT DUE TO DIFFERENCES IN PLANT COMPOSITION, POTENTIAL LIVESTOCK CARRYING CAPACITY VARIES GREATLY.

SOILS FOUND ON THE STUDY WATERSHEDS EXHIBITED THE HIGH ERODIBILITY CHARACTERISTICS OF THE GRANITIC SOILS FOUND IN THE IDAHO BATHOLITH. EROSION DATA WERE COLLECTED BY RILL SURVEYS, EROSION PINS, SPLASH PANS, AND SEDIMENT COLLECTION TROUGHS. ADDITIONAL DATA TO RECORD VEGETATION RESPONSES AND SOIL WATER REPELLENCY WERE COLLECTED USING A GRID SAMPLING TECHNIQUE. CONSIDERABLE EROSION OCCURRED AS THE RESULT OF OVERLAND FLOW AND RAINDROP SPLASH ON THE CLEARCUT WATERSHED. THERE WAS NO EVIDENCE OF EROSION FROM OVERLAND FLOW ON THE UNLOGGED WATERSHED, BUT THERE WAS SLIGHT SPLASH EROSION. CANOPY COVER EFFECTS AND LITTER PRODUCTION FROM THE FIRE-KILLED TREES WERE PROBABLY AN IMPORTANT FACTOR REGULATING EROSION ON THE UNLOGGED AREAS. GREATER FUEL LOADING AND THE CONSEQUENT MORE INTENSE BURN ON THE CLEARCUT AREA ALSO PROBABLY HAD AN EFFECT BY REDUCING SOIL SURFACE PROTECTION, INFLUENCING VEGETATION RESPONSES, AND INCREASING SOIL WATER REPELLENCY.

WHILE LAND MANAGERS RATE CHAPARRAL LOW IN COMMERCIAL VALUE, IT YIELDS ABOUT 0.1 ACRE-FOOT OF GOOD QUALITY WATER PER ACRE PER YEAR, AND PRODUCES FORAGE AND BROWSE FOR BIG GAME AND LIVESTOCK. BECAUSE OF A DWINDLING WATER SUPPLY IN CENTRAL ARIZONA, CONVERSION OF CHAPARRAL TO GRASS HAS BEEN CONSIDERED AS A MEANS TO AUGMENT STREAMFLOW. THE KEY TO INCREASING WATER YIELD IS REPLACEMENT OF DEEP-ROOTED SHRUBS WITH SHALLOW-ROOTED GRASSES AND FORBS. SHRUB ROOTS RAMIFY THE ENTIRE SOIL MANTLE AND CAN DEPLEE THE SOIL-WATER RESERVE TO A GREATER EXTENT THAN GRASSES AND FORBS. IN PREVIOUS EXPERIMENTS ON TREATED WATERSHEDS, STREAMFLOW INCREASED FROM 28 PERCENT IN OPEN BRUSH WITH LOW RAINFALL TO MORE THAN 300 PERCENT IN DENSE BRUSH WITH HIGH RAINFALL. CONVERSION PRACTICES MAY AFFECT WATER QUALITY BY TEMPORARILY INCREASING SUSPENDED SEDIMENT AND NUTRIENT LOADS, AND BY CONTAMINATION WITH HERBICIDES. IT IS PROBABLE THAT EROSION WILL INCREASE FOR A TIME FOLLOWING MOST CONVERSION PRACTICES WITH THE GREATEST EROSION FROM BROADCAST BURNING AND THE LEAST FROM MECHANICAL AND CHEMICAL CONTROL OF SHRUBS IF REPLACEMENT COVER IS ESTABLISHED SOON AFTER TREATMENT. ASSUMING THAT LARGE-SCALE CONVERSION TECHNIQUES CAN BE SUCCESSFULLY APPLIED, AND THAT 735,000 ACRES OF CHAPARRAL WOULD EVENTUALLY BE CONVERTED TO GRASS, THE EXPECTED DOWNSTREAM INCREASE WOULD AVERAGE ABOUT 150,000 ACRE-FEET EACH YEAR.

MAXIMUM FLOW RATES ON A BIG SAGEBRUSH WATERSHED WERE INCREASED THREE TO FIVE TIMES IN YEARS WITH THE FLOW AND SNOWMELT RUNOFF, EXPRESSED AS A PERCENT OF WINTER PRECIPITATION, WAS FOUR TIMES AS LARGE. WATER IS QUICKLY CONVEYED OFF THE WATERSHED SO THAT SOIL MOISTURE RECHARGE AND DEEP SEEPAGE LOSSES ARE MINIMIZED. THE MOST IMPORTANT FACTOR TRIGGERING OVERSNOW IS PROBABLY A CONSTRICTION IN FLOW AT THE GROUND-SNOW INTERFACE SINCE INTERMITTENT DRAINAGES DO NOT HAVE A PREFORMED CHANNEL TO CARRY WATER. OVERSNOW FLOW DEVELOPS WHEN PROLONGED, HIGH SNOWMELT RATES OCCUR AT THE BEGINNING OF SNOWMELT. DAILY MELT EXCEEDED 1 INCH PER DAY WHEN SNOW COVERED SAGEBRUSH PLANTS AND WAS GREATER THAN 2 INCHES PER DAY WHEN THE SNOW LEVEL WAS WITHIN SAGEBRUSH FOLIAGE. INCREASED SEDIMENT MOVEMENT ACCOMPANIED OVERSNOW RUNOFF EVENTS. SUSPENDED SEDIMENT CONCENTRATION REACHED 862 PPM WHILE OVERSNOW FLOW WAS OCCURRING IN COMPARISON TO LEVELS THAT ARE LESS THAN 20 PPM IN YEARS LACKING THE FLOW. ANNUAL COARSE SEDIMENT DEPOSITION WAS ALSO HIGHEST IN YEARS WITH THE FLOW AND RANGED FROM 8 TO 179 CU FT PER SQ MILE FOR ALL YEARS. DEPOSITION WAS 6 AND 12 TIMES GREATER THAN THE AVERAGE RATE FOR YEARS WITHOUT OVERSNOW RUNOFF.

THIS PAPER DESCRIBES A SIMPLIFIED CONCEPTUAL MODEL BASED ON THE MAXIMUM DISTANCE THAT A PARTICLE CAN TRAVEL BEFORE COMPLETE EVAPORATION, AND DERIVED FROM CONSIDERATION OF THE CONSEQUENCES OF A NON-UNIFORM PARTICLE SIZE DISTRIBUTION. MODEL PREDICTIONS AGREE WELL WITH SNOW ACCUMULATIONS MEASURED AT NUMEROUS SITES IN SOUTHEAST WYOMING OVER SEVERAL YEARS. RESULTS INDICATE A SIGNIFICANT PORTION OF THE WINTER'S PRECIPITATION IS LOST TO IN-TRANSIT EVAPORATION ON SITES WHERE SNOWFALL IS RELOCATED BY WIND. AN EXAMPLE IS GIVEN OF HOW THIS MODEL CAN BE USED TO ASSESS EFFECTS OF LAND MANAGEMENT PRACTICES ON THE TRANSPORT AND EVAPORATION OF BLOWING SNOW.

Erosion is the most serious pollutant originating from forestry activities. Activities which destroy the forest floor and reduce the infiltration rate of soil, such as mechanically preparing sites for tree planting, roads, skid trails, and logging decks, cause most accelerated erosion. Elevation of water temperature, changing the chemical composition of water by cutting or fertilizing stands, and introduction of pesticides and herbicides into streams are other common forms of pollution. Pollution from forestry operations can be minimized by utilizing existing information. However, there is need for additional quantification of pollution levels associated with alternative forestry practices, and for screening of known or development of new techniques for minimizing non-point source pollution.

SUBSTANTIAL BIAS AND VARIABILITY WERE FOUND. SOME OF THE SOURCES OF SAMPLE BIAS WERE SOROPTION, LEACHING, DIFFUSION, AND SCREENING OF PHOSPHATE IONS BY THE CUP WALLS. SAMPLE VARIABILITY OF NITRATE IONS WAS STRONGLY INFLUENCED BY SAMPLER INTAKE RATE, PLUGGING, SAMPLER DEPTH, AND TYPE OF VACUUM SYSTEM (WHICH SIMULATED DIFFERENT SAMPLER SIZES). THESE FACTORS AFFECT TIMING OF SAMPLE COLLECTION AND, BECAUSE NUTRIENT CONCENTRATION IN SOIL WATER IS CONTINUALLY CHANGING, THEY IN TURN AFFECT SAMPLE CONCENTRATION. THESE FACTORS PRODUCED AS MUCH AS A 60% RANGE IN SAMPLE CONCENTRATION FROM 8 SAMPLERS INSTALLED IN A SMALL UNIFORM PLOT. ADDED TO THIS VARIABILITY IS AN UNKNOWN AMOUNT OF BIAS REPRESENTING THE DIFFERENCE BETWEEN THE SAMPLE CONCENTRATION AND THE AVERAGE DRAINABLE SOIL-WATER CONCENTRATION. THE MANY FACTORS AFFECTING THE SAMPLE CONCENTRATION TOGETHER WITH THE DEMONSTRATED VARIABILITY AND UNKNOWN BIAS MAKE INTERPRETATION OF SAMPLER DATA DIFFICULT. TO REDUCE SAMPLE VARIABILITY, SAMPLERS SHOULD BE GROUPED BY INTAKE RATE. SHORT SAMPLING INTERVALS, UNIFORM SAMPLER LENGTHS, AND THE SAME INITIAL VACUUM SHOULD BE USED FOR ALL SAMPLERS.

A sampling technique was used to compute 1952 and 1972 land use acreage in flood plains as defined by the Standard Project Flood for the Connecticut and Westfield Rivers and by the 100-year flood for Mill River. Land use categories were agricultural, urban, water and wetlands, forest and abandoned land. In the total area, urban and forest land use increased in acreage from 1952 to 1972 while the other three declined. Structural flood plain management measures (dry-bed reservoirs and dikes were considered) would not have much effect on current agricultural land use. Non-structural alternatives discussed included flood damage insurance, flood proofing, relocation of buildings and land use regulation. Agricultural land, forest and grasslands are compatible with the flood plain and provide valuable storage capacity. Decline in agricultural acreage resulted from competition for land, the changing technology of agricultural production, inter-regional competition, competition for human resources, and high property taxes. Policies which restrict urban development in flood plains or make it more costly will have the tendency of reducing land competition, and therefore create a situation more desirable for extensive land uses.

AN ULTIMATE GOAL IS TO DEVELOP A MODEL THAT CAN BE USED TO ESTIMATE SUCH USE UNDER ANY LEVEL OF PLANT COVER AND FOR ANY COMPLEX OF SOIL, ASPECT AND SLOPE. THE RESULTS OF THE STUDY SUGGEST A FEASIBLE APPROACH IN DEVELOPING SUCH A MODEL. WATER BALANCES ARE COMPUTED BY COMBINING CALCULATIONS FOR PLANT WATER USE, SOIL WATER MOVEMENT AND ENERGY BALANCE. THE CURRENT RESEARCH TASK IS THE COMBINING OF ALL SNOW HYDROLOGY DATA INTO MODELS OF SNOWMELT WITH WHICH A LAND MANAGER, PRIOR TO TIMBER HARVEST, MAY PREDICT, THE EFFECTS OF ALTERNATIVE LAND MANAGEMENT PRACTICES UPON TIME OF WATER DELIVERY TO THE STREAMS. A SECOND TASK IS THE COMBINING OF THE SNOW HYDROLOGY, PLANT WATER USE AND SOIL WATER MOVEMENT DATA INTO MODELS WITH WHICH THE LAND MANAGER CAN DETERMINE PRIOR TO HARVEST THE OPTIMUM FORM OF HARVEST CUT FOR MAXIMIZING WATER YIELD, AESTHETIC CONSIDERATIONS, CHANGE IN TIME OF WATER YIELD OR OTHER MANAGEMENT OBJECTIVES.

TO ENCOURAGE A MULTIDISCIPLINARY APPROACH TO LAND TREATMENT PLANNING, SOME INSTITUTIONAL AND SOCIO-ECONOMIC ISSUES ARE HIGHLIGHTED HERE THROUGH A DISCUSSION OF ALTERNATIVE MEANS OF ACQUIRING AND MANAGING LAND TREATMENT SITES. IF A PUBLIC AGENCY PURCHASES THE LAND BY FEE SIMPLE ACQUISITION, MANAGEMENT CAN BE HANDLED BY SUBCONTRACTING FOR CUSTOM FARM OPERATIONS, OR THE LAND CAN BE LEASED TO FARMERS. THE LAND CAN ALSO BE RESOLD FOR PRIVATE USE WITH SOME LEGITIMATE CONDITIONS. EASEMENT PURCHASE, OR PARTIAL PROPERTY RIGHTS PURCHASE, IS ANOTHER ALTERNATIVE WHICH HAS THE ADVANTAGE THAT MANAGEMENT IS LEFT IN THE HANDS OF THE PRIVATE OWNER. A NEW APPROACH TO LAND ACCESS IS MUNICIPAL AND PRIVATE COOPERATIVE OWNERSHIP WITH DIVISION OF MANAGEMENT COSTS. SOME EXAMPLES ARE GIVEN OF EXISTING SYSTEMS AND THEIR MANAGEMENT.

The long axis was normal to prevailing wind. The profile of accumulated snow, less the mean amount of snow upwind of the clearing, was compared with the streamline patterns of airflow. Snow profiles are shown for 2 years where annual accumulation varied by a factor of 2. Snow accumulation was maximum in the clearing and minimum just behind the lee clearing edge. The maximum was centered about the upwind edge of the back eddy of airflow in the clearing. The minimum coincided with the downwind edge of the same eddy. These comparisons suggest that clearings may become saturated similar to snowfence systems, and that the accumulation pattern reflects primarily wind drift of falling snow rather than subsequent erosion and redeposition.

BY JULY 1, 1977, FEEDLOTS WITH POINT SOURCE DISCHARGES WILL BE REQUIRED TO HAVE IN USE THE BEST PRACTICABLE CONTROL TECHNOLOGY CURRENTLY AVAILABLE. THE GUIDELINES REQUIRE NO DISCHARGE OF WASTE WATERS FROM FEEDLOTS EXCEPT THOSE IN EXCESS OF CONTROL SYSTEMS DESIGNED TO ACCOMMODATE RUNOFF FROM LOCAL 10-YEAR, 24-HOUR RAINFALLS AND PROCESS GENERATED WASTE WATERS. THESE GUIDELINES ARE TO BE ADMINISTERED THROUGH NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM PERMITS FOR BEEF FEEDLOTS OF 1,000 HEAD OF MORE CAPACITY. (HOWEVER, BEEF FEEDLOTS OF SMALLER CAPACITY MAY BE EXPECTED TO COMPLY THROUGH NPDES OR STATE PERMIT PROGRAMS.) PRESENTED ARE ESTIMATES OF: (1) THE NUMBER OF BEEF FEEDLOTS WHICH COULD BE SUBJECT TO EFFLUENT GUIDELINES AND (2) THE ECONOMIC IMPACTS ON THE BEEF FEEDING INDUSTRY. AN ADDITIONAL $133 MILLION CAPITAL OUTLAY WOULD BE NECESSARY TO ALLOW THE 49,000 BEEF FEEDLOTS OF ALL CAPACITY LEVELS WITH PROBLEMS TO BE IN COMPLIANCE WITH EPA RULES BY 1977. THIS LEVEL OF INDUSTRY INVESTMENT WOULD BE NEEDED TO PROVIDE FEEDLOTS WITH CONTROL SYSTEMS CONSISTING OF DIVERSION TERRACES, A SETTLING BASIN, A RETENTION POND, AND PUMP IRRIGATION EQUIPMENT FOR DISTRIBUTING RUNOFF TO FARMLAND. AS THINGS NOW STAND, 95% OF THE INVESTMENT WOULD BE IMPOSED ON FEEDLOTS WITH LESS THAN 1,000 HEAD CAPACITY. INVESTMENTS COULD RANGE FROM $8 TO OVER $100 PER HEAD FOR FEEDLOTS OF LESS THAN 1,000 HEAD CAPACITY ADOPTING RUNOFF CONTROL SYSTEMS. FOR LARGER FEEDLOTS, PER HEAD INVESTMENT WOULD AVERAGE $1.40 TO $3.20.

THROUGHOUT THE YEARS, THE SIZE OF THE DAIRY FARMS HAS STEADILY INCREASED. HOWEVER, THE PROXIMITY OF MANY OF THE LIVESTOCK YARDS TO PERENNIAL STREAMS, MANY OF WHICH ARE TROUT STREAMS, HAS NOT CHANGED. AS A RESULT, THE LARGER HERDS HAVE INCREASED THE PROBLEM OF HANDLING THE LARGE VOLUMES OF MANURE PRODUCED EACH DAY. ONE METHOD OF HANDLING THESE LIVESTOCK WASTES INVOLVES THE USE OF MANURE PUMPS. ALTHOUGH THE COMPANIES WHICH FABRICATE MANURE PUMPS ARE FEW, A CONSIDERABLE NUMBER OF THESE INSTALLATIONS HAVE BEEN MADE. MANY OF THESE SYSTEMS HAVE BEEN VERY SUCCESSFUL. THE MANURE HAS BEEN REMOVED FROM THE BUILDINGS AND SUCCESSFULLY STORED FOR THE DESIRED PERIOD OF TIME WHILE GREATLY REDUCING SURFACE WATER POLLUTION. THE DESIGN AND OPERATION OF A COMPLETE MANURE HANDLING SYSTEM FOR A FARM LOCATED IN KEWAUNEE COUNTY ARE DESCRIBED. ALTHOUGH THIS SYSTEM WAS RELATIVELY INEXPENSIVE, THE CAPACITY IS SUFFICIENTLY LARGE TO STORE THE TOTAL MANURE ACCUMULATION OF 100 CATTLE FOR THE ENTIRE WINTER SEASON.

(RUSSIAN THISTLE) WERE ALLOWED TO IMBIBE ON FILTER PAPER IN PELTIER THERMOCOUPLE PSYCHROMETER CHAMBERS WITH DIFFERING AMOUNTS OF WATER AVAILABLE. WATER POTENTIAL DETERMINATIONS MADE ON THE SYSTEM PERIODICALLY DURING THE 24 HOUR PERIOD OF IMBIBITION SHOWED THAT AT THE 24TH HOUR, COMPLETE EXTENSION OF THE EMBRYONIC AXIS OCCURRED AT AN EQUILIBRIUM WATER POTENTIAL OF -2 BARS AND AN EMBRYO WATER CONTENT OF 114%, PERCEPTIBLE GROWTH (UNCOILING OF THE SPIRALED EMBRYO) AT -30 BARS AND 83%, AND NO GROWTH OR PERCEPTIBLE SWELLING AT -54 BARS AND 56%. IN SALSOLA, EVIDENCE OF GROWTH OCCURS AT WATER POTENTIALS WELL BELOW THOSE THAT PERMIT GERMINATION IN OTHER SPECIES INVESTIGATED, AND EXTENSIVE GROWTH OCCURS IN ABOUT THE SAME RANGE AS ROOT PROTRUSION IN THE OTHER SPECIES INVESTIGATED. HOURLY MONITORING OF THE WATER POTENTIAL OF THE PLANT-SUBSTRATE SYSTEM SHOWED AN INITIAL RISE TOWARD A LEVEL THAT WOULD BE ATTAINED BY THE WETTED FILTERED PAPER ALONE AND THEN A DECLINE TO LOWER WATER POTENTIAL VALUES AT INTERMEDIATE LEVELS OF WATER AVAILABILITY. THIS REVERSAL IS ASCRIBED TO THE INCREASING EFFECTS OF THE OSMOTIC AND MATRIC COMPONENTS OF THE TOTAL WATER POTENTIAL OF THE PLANT TISSUE DURING IMBIBITION AND GROWTH.

The correlation coefficient r was 0.989 for 45 soil samples. A double sampling approach using both analyses to estimate total N was more efficient than Kjeldahl analyses only. Example applications are presented under cost and precision limitations. The regression can also be used to obtain point values of total N for mapping or other nonstatistical purposes.

Streams fed by mountain snowmelt exhibit sharply peaked hydrographs. During the peak runoff period most water rights can be served. Thereafter streamflow declines rapidly, and many of the later water rights are denied water. Farms that are prohibited from diverting water suffer reduction in crop yields and income. To get the most benefit from varying flow, streams must be closely monitored so that as many rights as possible can be served with the original flow and the return flow that occurs.

THIS ARTICLE COMPARES ALTERNATIVE POLICIES TO ACHIEVE A SPECIFIED NITROGEN POLLUTION STANDARD IN SUBSURFACE IRRIGATION RETURN FLOWS. THE SAN LUIS UNIT OF THE CENTRAL VALLEY PROJECT IS USED AS A CASE STUDY. BAUMOL AND OATES' ENVIRONMENTAL PRICING AND STANDARDS APPROACH TO THE CONTROL OF EXTERNALITIES IS UTILIZED. THIS APPROACH INVOLVES THE ESTABLISHMENT OF A SOCIALLY ACCEPTABLE STANDARD OF ENVIRONMENTAL QUALITY AND SUBSEQUENT IMPOSITION OF A SYSTEM OF CHARGES ON EFFLUENT EMISSIONS TO ACHIEVE THE QUALITY STANDARD. THIS WILL NOT NECESSARILY YIELD A PARETO-EFFICIENT ALLOCATION OF RESOURCES, BUT FOR ANY GIVEN VECTOR OF FINAL OUTPUTS, THE CORRECT SET OF EFFLUENT CHARGES CAN ACHIEVE THE STANDARD AT THE LEAST POSSIBLE COST. A MULTIPERIOD LINEAR PROGRAMMING MODEL BASED ON AN INFINITE PLANNING HORIZON HAS BEEN UTILIZED TO DERIVE A SET OF CROPPING PATTERNS TO MAXIMIZE THE PRESENT VALUE OF ALL FUTURE RETURNS TO LAND AND MANAGEMENT, SUBJECT TO THE SUPPLY OF RESOURCES AND THE COST OF SUBSURFACE DRAINAGE WATER DISPOSAL. THE BAUMOL-OATES PRICING AND STANDARDS APPROACH IS APPLIED TO DETERMINE THE LEAST COST POLICY IN ACHIEVING A 2 PPM NO3-N STANDARD ON THE DISPOSAL OF DRAINAGE WATER. THE COST IS ESTIMATED TO BE 38% OF THE COST OF INTERNALIZING TREATMENT COSTS. (BELL-CORNELL) JF - AMERICAN JOURNAL OF AGRICULTURAL ECONOMICS, VOL. 57, NO. 1, P 33-39, FEBRUARY 1975. 3 TAB, 12 REF.

They therefore compete with one another for a variety of ligands (Pulido and others, 1966a; Gunn and others, 1968). Because cadmium is considered to have only adverse effects in biological systems (Friberg and others, 1971) and zinc is an essential nutrient (Sandstead, 1973), the significance of their competitive interactions for health merits investigation. In this paper we will examine the hypothesis that competition between zinc and cadmium for biological ligands has important implications for health. ZINC AND CADMIUM IN THE ENVIRONMENT Cadmium is a relatively rare element. Its average concentration in the Earth"s crust is about 0.5 ppm (Heindl, 1970). In nature it is closely associated with zinc (Friberg and others, 1971). The zinc:cadmium ratio of most minerals and soils ranges from 100:1 to 12,000:1 (Bowen, 1966; Schroeder and others, 1967). In the United States, cadmium is obtained commercially only as a by-product during the processing of zinc-bearing ores (Heindl, 1970). Its production has risen steadily during the past three decades (Moulds, 1969). This growth can be described by the equation y = 0.21x - 1.81, where y represents the annual production in millions of pounds and x is the year minus 1900. Sixty percent (8 million pounds in 1968) of the cadmium produced each year is used for electroplating (Heindl, 1970), and products plated with cadmium are widely used throughout the United States (Flick and others, 1971). Such cadmium-plated products and cadmium-containing materials may be . . .

The watersheds studied were a fescue grass catchment, a 15-year old white pine plantation, and a mature undisturbed hardwood forest. Monthly averages of nitrate-nitrogen in stream water from the three watersheds were 730, 190, and 3 ppb respectively; the respective nitrifying populations averaged 16,000, 175 and 22 per gram of dry weight for each 40 cm soil profile. These populations were concentrated in the upper 10 cm of the profile (grass = 98%, white pine = 90%, and hardwood = 88%). A correlation is evident between the number of nitrifying bacteria in the soil from gaged watersheds and the NO3 content of the streams. Nitrifying activity appears to be dependent on vegetation type and successional stage. (Forest Service) JF - Agro-Ecosystems Vol 2, p 127-132, 1975. 3 fig, 1 tab, 11 ref.

Excessive soil erosion from both wind and water accompanied the efforts of many farmers to increase crop production. Contributing to the year 's poor record was some of the worst weather in years. But severe erosion could also be traced to the unwise selection of certain soils for cultivated crops as well as the existence of too few conservation measures on the land.

To meet these goals, land managers annually are drastically disturbing many thousands of hectares by tree crushing, brush chopping, disking, windrowing, bedding, burning, and chemical treatment to remove competing vegetation and prepare the soil for pine. Though evidence is limited, literature on past forest and agricultural practices resembling such intensive techniques indicates that there may be reason for concern. The environmental values at stake suggest research to determine (1) what significant changes in soil and water quality result from intensive forestry; (2) whether changes are adverse; and (3) if adverse, how practices can be modified to allow management for high yields without damaging impacts. Described are some of the considerations involved in such research, including initial survey and development of a sampling scheme. (Forest Service) JF - Forest Soils and Forest Land Management.

BECAUSE OF INCREASED LOGGING, ROAD CONSTRUCTION, AND SEVERE FLOODS AFTER 1950, EXCESSIVE SEDIMENT, ESPECIALLY FINES, WAS DEPOSITED IN THE RIVER CHANNEL, SERIOUSLY DAMAGING THE MAJOR SPAWNING AREAS BY 1966. A STUDY WAS DESIGNED TO EVALUATE TRENDS IN THE SIZE OF RIVERBED SURFACE MATERIALS IN FOUR MAJOR SPAWNING AREAS IN THE UPPER HALF OF THE RIVER. THE SIZE COMPOSITION OF MATERIALS FAVORABLE FOR SPAWNING IMPROVED GREATLY FROM 1966 TO 1974; A LARGE DECREASE IN FINES WAS ACCOMPANIED BY A LARGE INCREASE IN GRAVELS AND A LESSER INCREASE IN RUBBLE. THE CHANGE IN SPAWNING MATERIALS RESULTED FROM A REVERSAL OF THE PREVIOUS HIGH RATE OF SEDIMENT FLOW INTO THE CHANNEL SYSTEM COMPARED TO SEDIMENT FLOW OUT OF THE SYSTEM. THE REDUCTIONS IN WATERSHED EROSION AND SEDIMENT ENTRY INTO THE RIVER RESULTED FROM: (1) A MORATORIUM ON LOGGING AND ROAD CONSTRUCTION ACTIVITIES ON THE WATERSHED; (2) NATURAL WATERSHED STABILIZATION PROCESSES; AND (3) A WATERSHED REHABILITATION PROGRAM. THIS STUDY DEMONSTRATES THAT SEDIMENT DAMAGE TO A VALUABLE FISHERY RESOURCE IS NOT IRREVOCABLE AND ILLUSTRATES THE NEED TO PROGRAM FUTURE LOGGING AND ROAD CONSTRUCTION OVER BOTH TIME AND SPACE TO AVOID DEGRADATION OF SALMONID SPAWNING AREAS.

It is based on the assumptions that the region is internally homogeneous in each soil management group; constant returns per acre are obtained for each soil management group; available cropland acreage limits production and all crops compete for it; farmers minimize crop production costs; demands for food and fiber are exogenously determined and known; and available resources, input-output coefficients, and prices are known. If appropriately modified, this model can be used as an analytical framework and data base to evaluate agricultural benefits of proposed flood-control projects. Such a project evaluation model can estimate the cost of producing specified outputs from an area under conditions of present flood hazards and with flood protection. Differences between these two estimates provide a single measure of benefits reflecting direct damage reduction and net regional enhancement effects. The model also can provide estimates of probable land use changes associated with a change in the level of flood protection.

RESPONSES OF TOTAL EVAPOTRANSPIRATION RATES TO FOREST COVER CHANGES INDICATE THAT SOIL EVAPORATION IS REDUCED BY EVEN LIMITED CUTTING. SMALL REDUCTIONS IN NET EVAPOTRANSPIRATION INCREASE NET WATER YIELDS. WHEN LESS THAN 10% OF THE STAND IS REMOVED, INCREASES CANNOT BE DETECTED BY HYDROLOGICAL METHODS, AND WATER YIELD RESPONSES ARE NOT LINEAR. THE GENERAL MODEL SHOULD BE USED CAUTIOUSLY IN CASES OF PATCH CLEARCUTTING, STRIP CUTTING, OR SINGLE TREE SELECTION WHERE A SUBSTANTIAL BASAL AREA IS REMOVED, BUT SHOULD BE SATISFACTORY WHERE A SMALL PERCENTAGE OF THE BASAL AREA IS REMOVED. THE MODEL PROVIDES LOGICAL PREDICTIONS OVER THE ENTIRE RANGE OF THE INDEPENDENT VARIABLE AND IS SO FLEXIBLE THAT OTHER CURVE FORMS WILL ONLY REQUIRE NEW ESTIMATES OF PARAMETERS RATHER THAN NEW ALGEBRAIC FORMS.

AN EQUATION IS PRESENTED TO PREDICT THE ANNUAL INCREASE IN STREAMFLOW FROM THE PERCENT BASAL AREA CUT AND FROM THE THEORETICAL EXTRA-TERRESTRIAL RADIATION LOAD FOR THE WATERSHED. TIMING OF THE INCREASED FLOW FROM WATERSHED EXPERIMENTS DEPENDS ON THE MAGNITUDE OF THE INCREASE, BUT RESULTS CONSISTENTLY SHOW THAT MUCH OF THE INCREASE APPEARS IN THE LOW-FLOW SEASON. TWO WATERSHED EXPERIMENTS INDICATE THAT CONVERSION OF HARDWOODS TO WHITE PINE SUBSTANTIALLY REDUCES MONTHLY AND ANNUAL STREAMFLOW. CONVERSION OF A HARDWOOD-COVERED WATERSHED TO GRASS PRODUCES UP TO 5.8 INCHES OF INCREASED FLOW PER YEAR. ALTHOUGH SOME INCREASE IN NUTRIENT EXPORT OCCURS FROM FOREST CUTTINGS AND SPECIES CONVERSIONS, THE INCREASE IS WELL WITHIN DRINKING-WATER STANDARDS.

APPLIED NITRATE WAS REMOVED AT A RATE OF 87.4% DURING 24 DAYS AT 24C AND 62% DURING 27 DAYS AT 13C. THE USE OF SAWDUST AS AN OXIDIZABLE MATERIAL HAD LITTLE EFFECT UPON NITRATE REMOVAL. THE FLUX WAS MAINTAINED AT APPROXIMATELY 0.23 CM/HR. THE PRODUCTION OF GASES WHICH ACCOMPANIED THE DENITRIFICATION PROCESS DESATURATED THE METHANOL COLUMNS AND INFLUENCED THE FLOW RATE. THE BREAKTHROUGH CURVES OBSERVED INDICATED THAT THERE MAY HAVE BEEN SIGNIFICANTLY DIFFERENT EFFECTIVE DIFFUSION COEFFICIENT FOR NITRATE AS COMPARED WITH CHLORIDE. THE PASSAGE OF NITRATE AND CHLORIDE THROUGH THE COLUMNS WAS ACCOMPANIED BY AN INCREASE IN REDOX POTENTIAL AND, IN SOME CASES, A DISCOLORATION OF THE EFFLUENT. THE REMOVAL OF A HIGH PERCENTAGE OF NITRATE AT RELATIVELY LARGE PORE VELOCITIES WAS ENCOURAGING FOR THE PROSPECT OF REMOVING EXCESS NITRATE FROM SOIL WATER IN THE VICINITY OF TILE DRAINS.

Pedestrian circulation, noise absorption, sign systems, and views are typical of the complex landscape aspects that should be planned in addition to water conservation. Among these, the visual aspects seem most neglected, and the author explains, using a model, the visual resource theory. JF - Trans. Am. Soc. Agric. Engin.

AN - 17947207; 5227424 AB - This investigation was conducted to determine the conc of 2, 4, 5-T [2, 4, 5-trichlorophenoxy) acetic acid] and picloram (4-amino-3, 5, 6- trichloropicolinic acid) in subsurface water after spray applications of the herbicides to the surface of a seepy area watershed and lysimeter in the Blacklands of Texas. A 1:1 mixture of the triethylamine salts of 2, 4, 5-T + picloram was sprayed at 2.24 kg/ha every 6 months on the same area for a total of 5 applications. Herbicide content in the Houston Black clay during the study ranged from 0 to 162 ppb. Herbicide content on grass was high (28 to 113 ppm) immediately after spraying, but degraded rapidly after each treatment. Conc of 2, 4, 5-T and picloram in seepage and well water from the treated area was extremely low (< 1 ppb) during the 3-yr study. No 2, 4, 5-T was detected from 122 drainage samples from a field lysimeter sampled for 1 yr after treatment with 1.12 kg/ha of 2, 4, 5-T + picloram (1:1).Picloram was detected in small amounts (1 to 4 ppb) 2 to 9 months after treatment in lysimeter water.

AN - 17035078; 5253981 AB - Extremely low concs of insect growth regulators (IGR's) has controlled mosquitoes, midges, flies, and biting lice in field tests. This effectiveness is undoubtedly related to the protected habitat of many of these pests of man and animals. Thus, spp of Aedes have been controlled by applying s little as 0.14 kg IGR/hectare of water surface to the larval environment, but other spp of mosquitoes such as Culex must be treated with much higher concs. All insects tested have shown marked susceptibility at a certain stage: 4th-instar Aedes larvae are controlled with 0.014 kg /hectare, but populations of mixed ages require 10 times that amount. Slow-release formulations of IGR's or those that protect the IGR from u.v. light are more effective. Otherwise, repeated applications are usually necessary to control a population containing all stages of a spp. Development of new methods of application is being increasingly stressed, and feeding the IGR to cattle to control manure-breeding insects has been successful. Some IGR's have a rather broad-spectrum effect, particularly against manure-breeding flies; others are selective, and a considerably greater quantity is needed for control of one sp of fly than for control o another sp.

AN - 17031717; 5250699 AB - The results are reported of a Soil Conservation Service (SCS) project started in 1970 with the aim of evaluating plants for their tolerance to wave action, since wave erosion is a serious problem on floodwater retarding dams in Texas. Selected spp (water-loving or water-tolerant with extensive fibrous root systems) were removed from native sites and transplanted to the shorelines of 7 structures. Samples of these plants were studied internally at the SCS Plant Materials Center, Knox City, Texas and since 1970, 39 additional dams have been planted and material grown at the Center. Common reedgrass, giant reedgrass, switchgrass and prairie cordgrass have been proved to be well adapted for controlling wave erosion while giant cutgrass and maidencane are promising in areas with a reliable source of water. Low-growing shrubs e.g. indigobush, buttonbush, etc. make good back-up plants. Improved strains of grasses have evolved at the Center e.g. a new switchgrass which starts growth early in spring, tolerates flooding and has late-maturing seeds eaten by birds. JF - Soil. Conserv.

Since its inception in the mid-1930's, the SCS has followed this concept in all its programs. Within the last 20 years, as the programs of the SCS have become more water-management oriented, these same multiple objective concepts have guided the planning process. The SCS participated actively in the development and testing of the Water Resources Council 's Principles and Standards. Discussed are limitations of the approved Principles and Standards and problems in implementation. Considered next are: The Optimum National Economic Development Plan (ONED); the Environmental Quality Plan; alternative plans; public participation; regional development; and additional needs wherein a wide range of environmental goals is needed. In conclusion the SCS fully supports the concept of multiple objective planning and has done this consistently throughout its agency life. Although it is encountering problems, several of these problems offer opportunities for research; answers or more rational procedures are essential to the effective and complete implementation of this process.

A NUMBER OF NEW THEORIES ABOUT THE HYDROLOGY OF WARM SNOW, DEVELOPED FROM STUDIES AT THE U.S. FOREST SERVICE'S CENTRAL SIERRA SNOW LABORATORY, ARE AT VARIANCE WITH OLDER AND GENERALLY ACCEPTED THEORIES. SOIL TEMPERATURE APPEARS TO HAVE LITTLE EFFECT ON SNOWMELT BECAUSE MELT OR RAIN WATER FROM THE PACK KEEPS THE SOIL COOL AND MINIMIZES VAPOR TRANSFER OF HEAT. SNOW TEMPERATURES REMAIN NEAR THE FREEZING POINT IN ALL BUT THE SURFACE FEW INCHES IN MOST YEARS. SNOWMELT AND WATER MOVEMENT FROM THE PACK OCCUR THROUGHOUT MOST WINTERS REGARDLESS OF PACK DENSITY, BUT DENSITY LAYERING AND DIFFERENTIAL MATURATION OF THE SNOWPACK WILL MATERIALLY AFFECT WATER MOVEMENT. DIFFERENCES IN THE AMOUNT OF SNOW FOUND IN CONTIGUOUS FOREST AND OPEN SITES APPEAR TO BE LARGELY THE RESULT OF DIFFERENTIAL AERODYNAMIC PLACEMENT. SNOW INTERCEPTION AND SUBSEQUENT EVAPORATION FROM TREE CROWNS ARE PROBABLY A SOURCE OF ONLY MINOR LOSSES.

THE IMPORTANCE OF THE SNOWPACK WAS EVALUATED IN RELATION TO CHEMICAL INPUTS TO THE FOREST ECOSYSTEM AND TO CHEMICAL OUTPUTS IN STREAMFLOW. THE SNOWPACK WAS SLIGHTLY LESS ACID AND HAD ABOUT THE SAME OR LOWER CONCENTRATIONS OF CALCIUM, NITRATE, AND SULFATE THAN INCIDENT PRECIPITATION. POTASSIUM OCCURRED IN HIGHER CONCENTRATIONS IN THE SNOWPACK THAN IN PRECIPITATION, POSSIBLY AS A RESULT OF LEACHING FROM ORGANIC MATTER INCORPORATED IN THE SNOWPACK. JUST BEFORE SPRING MELT THE SNOWPACK CONTAINED ABOUT 50% OF THE TOTAL CALCIUM AND 25% OF THE TOTAL NITRATE AND SULFATE INPUT TO THE ECOSYSTEM IN WINTER PRECIPITATION. POTASSIUM IN THE SNOWPACK JUST BEFORE MELT WAS NEARLY TWICE THE AMOUNT OF INPUT BY WINTER PRECIPITATION.

INCLUDED IN THIS EXAMINATION ARE WATER QUALITY AND QUANTITY, OVERSTORY VEGETATION, UNDERSTORY VEGETATION, POTENTIAL LIVESTOCK CARRYING CAPACITY, WILDLIFE VALUES, AND RECREATION AND AESTHETICS. PINYON-JUNIPER REMOVAL WAS DONE BY CABLING, HERBICIDE, AND FELLING IN AN ATTEMPT TO IMPROVE WATER YIELDS. OF THE THREE TREATMENTS ONLY THE HERBICIDE TREATMENT WITH PICLORAM APPEARS TO PROVIDE AN INCREASE IN WATER YIELD, BUT THE NEGATIVE AESTHETIC EFFECT OF DEAD STANDING TREES WAS UNDESIRABLE. OVERSTORY VEGETATION REMOVAL WILL RESULT IN A SEVERALFOLD INCREASE IN HERBAGE PRODUCTION FOR LIVESTOCK AND WILDLIFE. THERE WAS NO MEANINGFUL INCREASE IN SEDIMENT YIELD AS A RESULT OF OVERSTORY REMOVAL. A COMBINATION OF HERBICIDE TREATMENT AND FIRE APPEARS THE MOST PROMISING METHOD FOR FUTURE JUNIPER CONTROL RESEARCH FROM THE STANDPOINT OF WATER PRODUCTION, FORAGE PRODUCTION, DEER RESPONSE, AND ECONOMICS.

PROJECT FEASIBILITY IS NOW BEING DETERMINED BY CONCERNS OTHER THAN JUST NATIONAL ECONOMIC EFFICIENCY. A HIGHLY IMPORTANT TASK TODAY IS TO EVALUATE FEEDBACK, FOCUSING ON THE OBJECTIVE OF ENVIRONMENTAL QUALITY. THE CRITERIA WHICH MUST BE MET BY ANY SYSTEM DESIGNED TO QUANTIFY AESTHETIC QUALITY ARE DISCUSSED. INCLUDED IS A DESCRIPTION OF STUDIES DEALING WITH THE AESTHETIC APPRAISAL OF FOREST STANDS. PRESENTED IS A LIST OF TWELVE CRITERIA BEING USED TO EVALUATE AND JUDGE A NEW TECHNIQUE FOR QUANTIFYING THE PUBLIC'S PERCEPTIONS OF WINDLAND AREAS MANAGED IN DIFFERENT WAYS. CONSIDERED ARE SIX DIFFERENTIALLY-MANAGED PINE WATERSHEDS. THE APPROACH IS BASED ON EXTENSIONS OF PSYCHOLOGY'S THEORY OF SIGNAL DETECTION AND ON A SYSTEMATIC CONCEPTUAL MODEL. DISCUSSED ARE SOME IDEAS REGARDING THE STRAW MAN' PLANNING SCHEME AS A POSSIBLE SOLUTION FRAMEWORK FOR QUANTIFYING AESTHETICS RELATED TO WATER RESOURCES DEVELOPMENT. THE 'STRAW MAN' ALLOWS FOR COMPREHENSIVE PLANNING AND CRITICAL FEEDBACK. DESIRABLE TRAITS OF METHODS DESIGNED TO QUANTIFY ASPECTS OF ENVIRONMENTAL PERCEPTION INCLUDE CONDUCIVENESS TO PUBLIC INVOLVEMENT AND THEORETICAL SOUNDNESS.

LOCAL FORESTERS SUSPECTED HIGHWAY DEICING SALT AS THE CAUSE OF DAMAGE. A BIOLOGICAL EVALUATION WAS BEGUN IN THE SPRING OF 1973 TO DETERMINE THE CAUSE AND DISTRIBUTION OF DAMAGE TO THE ROADSIDE CONIFERS, THE SPECIES AFFECTED, AND THE RELATIONSHIP OF TREE DAMAGE TO THE DISTANCES OF TREES FROM THE HIGHWAYS. ESTIMATES FROM THE EVALUATION INDICATED THAT SOME 3000 TREES DIED OR WERE DAMAGED ON MORE THAN 300 LOCATIONS IN THE BASIN. BROWNING OF FOLIAGE, BRANCH DIEBACK, AND IN MANY CASES, DEAD TREES OF ALL SIZES AND AGES WERE OBSERVED. DAMAGE AND DEATH WERE GREATER FOR TREES NEAR HIGHWAYS AND LESS FOR TREES AT GREATER DISTANCES FROM THE HIGHWAYS; IN SOME CASES DAMAGE OCCURRED UP TO 60 FEET FROM THE PAVEMENT. TESTS IN THE GREENHOUSE, WHICH INVOLVED ADDING DIFFERENT CONCENTRATIONS OF SALT SOLUTION TO POTTED TREES, DUPLICATED SYMPTOMS AND DAMAGE OBSERVED IN THE FIELD. IT WAS CONCLUDED THAT SALT APPLIED TO THE HIGHWAYS IS A MAJOR CAUSE OF DAMAGE AND DEATH TO ROADSIDE CONIFERS IN THE BASIN. DAMAGE PROBABLY WILL CONTINUE TO OCCUR IF THE USE OF SODIUM CHLORIDE FOR HIGHWAY DEICING CONTINUES AT THE PRESENT LEVEL.

THE AREA HAS A WIDE VARIETY OF SOILS, AND NATURAL FIRES HAVE OCCURRED OVER THE PAST 50 YEARS. FOLLOWING NATURAL FIRES, GRASSES BECAME SIGNIFICANT ONLY ON SOILS WITH SANDY SURFACE TEXTURES. PINYON-JUNIPER WAS THE DOMINANT SPECIES IN THE ABSENCE OF FIRE REGARDLESS OF THE SOIL TYPE. NO SIGNIFICANT AMOUNTS OF GRASS WERE PRODUCED AT ANY PLATY SURFACE LAYER. SOILS WITH THIS CHARACTERISTIC HAVE POOR WATER INFILTRATION RATES AND HIGH RUNOFF RATES ELIMINATING THOSE PLANTS THAT ARE UNABLE TO COMPETE FOR LIMITED MOISTURE. PINYON, JUNIPER, AND SHRUBS ARE THE PRINCIPAL PLANTS PRODUCED ON THESE SOILS.

FELLING WITH POWER SAWS WAS USED TO ELIMINATE SOIL PITS AREATED BY UPROOTING THROUGH CABLING OR PUSHING. THESE PITS ARE CONSIDERED UNDESIRABLE BECAUSE THEY REDUCE RUNOFF BY RETAINING SURFACE WATER, ARE A POTENTIAL SOURCE OF SEDIMENT, AND MUCH OF THE COOL SEASON GRASSES ARE DESTROYED WHICH NORMALLY GROW BENEATH THE TREE CROWNS. HERBAGE INCREASES WERE HIGHLY VARIABLE WITH LITTLE OR NO RESPONSE IN 3 OF THE 7 POST-TREATMENT YEARS. INDICATIONS ARE THAT AVERAGE HERBAGE PRODUCTION MAY REACH A NEAR STEADY STATE WITHIN SEVERAL YEARS AFTER TREE REMOVAL. LITTLE EFFECT OF THE TREATMENT ON GROUND COVER AND RANGE CONDITION WAS DETECTED SUGGESTING THAT MAJOR CHANGES WILL EITHER TAKE LONG PERIODS OF TIME OR REQUIRE MAJOR CHANGES ON GRAZING MANAGEMENT.

IT IS ARGUED THAT GULLY DEVELOPMENT SHOULD BE RECOGNIZED IN TERMS OF LAND FORM EVOLUTION, PROCEEDING FROM YOUNG TO OLD AGE STAGES. YOUTHFUL AND EARLY MATURE STAGES OF GULLY DEVELOPMENT WERE ESTABLISHED. COMPARISON OF HYDRAULIC GEOMETRY OF GULLIES WITH THAT OF RIVERS SUGGESTS THAT THE MATURE STAGE SHOULD BE CHARACTERIZED BY DYNAMIC EQUILIBRIUM. ALTHOUGH THIS STAGE WAS APPROACHED BY SOME STUDY GULLIES, ITS EXISTENCE COULD NOT BE VERIFIED. IN EPHEMERAL GULLIES, CRITERIA OF A MATURE GULLY STAGE MAY NOT BE GIVEN BY STREAM EQUILIBRIUM ALONE, BUT MAY INCLUDE OTHER ASPECTS OF STABILITY SUCH AS CHANNEL VEGETATION. DIFFICULTIES EXIST IN PREDICTING SEDIMENT PRODUCTION AND YIELD FOR EARLY STAGES OF GULLY DEVELOPMENT. IN EPHEMERAL GULLIES, SEDIMENT LOADS ARE OFTEN MORE CLOSELY RELATED TO TIME AND DURATION OF FLOW THAN TO MAGNITUDE OF FLOW. EROSION RATES DURING AN INDIVIDUAL FLOW DEPEND NOT ONLY ON THE STAGE OF GULLY DEVELOPMENT, BUT ALSO ON THE STABILITY OF THE GULLY AT THE TIME OF FLOW.

AN OPTIMUM SYSTEM DESIGN CANNOT BE OBTAINED WITHOUT KNOWLEDGE OF THE CORRECT INPUTS TO THE DRAINAGE DESIGN EQUATION. TWO PROGRAMS ARE PRESENTED FOR USING THE COMPUTER TO DESIGN SUBSURFACE DRAINAGE SYSTEMS FOR IRRIGATED AREAS. THE FIRST CALCULATES DRAIN SPACINGS USING THE DUMM, MOODY, AND TAPP NONSTEADY-STATE TRANSIENT FLOW METHOD, WHICH PROVIDES CLOSE CORRELATION BETWEEN THEORY AND PRACTICE. THE SECOND PROGRAM PROVIDES DRAINAGE SYSTEM LAYOUTS IN AN AREA REQUIRING DRAINAGE FOR ANY SPECIFIED DRAIN SPACING AND DRAIN DEPTH. USING THESE TWO PROGRAMS, ALL INPUT PARAMETERS CAN BE INVESTIGATED AND THE EFFECT OF THEIR VARIANCE ON BOTH DRAIN SPACING AND SYSTEM COST CAN BE FOUND. THUS, A SENSITIVITY RELATIONSHIP BETWEEN THE DRAIN SPACING AND SYSTEM LAYOUT, AND THE PARAMETERS USED IN CALCULATING THE SPACING, CAN BE DEFINED.
