Microhabitat Selection And Diel Movements Of Juvenile Rainbow Trout (Salmo Gairdneri) Introduced Into Mid-Elevation Reservoirs In Utah, Wayne A. Wurtsbaugh, Roger Tabor

Watershed Sciences Faculty Publications

The distribution and movement patterns of fingerling rainbow trout stocked into reservoirs in Utah were investigated with · SCUBA observations and by vertical gill netting. For several weeks after stocking, fingerling trout (ca. 80 mm standard length) were strongly oriented to the shore, and selected habitats providing cover. During the underwater observations, no fish were seen below depths of 2 meters. Two weeks after stocking, the fingerlings were most abundant under docks near where they were planted, indicating that dispersal was relatively slow. Jacob's electivity indices for natural substrates in water 0-1.5 meter deep were in sand, gravel, cobble, boulders …

Importance Of Predation By Adult Trout On Mortality Rates Of Fingerling Rainbow Trout Stocked In East Canyon Reservoir, Utah, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

Personnel from Utah State University, working in cooperation with the Utah Division of Wildlife Resources and the Utah Cooperative Fish and Wildlife Research Unit, are attempting to determine various sources of mortality of fingerling rainbow trout (Salmo gairdneri) stocked into mid-elevation reservoirs in the State. Returns of planted fish are often much below desired levels. Angler surveys indicate that in East Canyon Reservoir, fishermen harvest only about 30% of the fingerling trout stocked, and this is a much higher return than in many other waters.

Engineering Treatment Of Hazardous Wastewaters Utilizing Dye-Sensitized Photooxidation, Betty-Ann Naeger, R. Ryan Dupont, William M. Moore

Reports

Studies were conducted to determine the applicability of photooxidation for the degradation of selected hazardous and refractory organic compounds. These photochemical oxidation reactions occur through the transfer of energy from electronically excited sensitizer molecules which attain excited states by absorbing visible light energy. Optimum conditions for photooxidation were established based on sensitizer concentration and reaction pH for four polynuclear aromatic pollutants. The rate of photooxidation was found to be independent of the initial substrate concentration for methylene blue-sensitized reactions, and dependent on substrate concentration for solutions without a sensitizing dye. Photolysis of substrate mixtures established acridine and anthracene as photochemically …

Expected Water Surface Levels For The Great Salt Lake, L. Douglas James

Reports

Flooding at the Great Slat Lake could become a major disaster through the high cost of coping with the rising level, sudden collapse of protective levees, failure of pumping to the West Desert to induce increased evaporation, or, fiscally, by a rapid drop in the lake level just after a large protective decision making in the private sector, provide for the design of hydrologically safe levees, and optimize pumping schemes for moving water within a partitioned lake. Doing so will require crossing major theoretical frontiers in the study of basin scale hydrology in an arid climate and for forecasting extreme …

A Prototype For Quality: Bryce Canyon National Park Interpretive Prospectus, 1987, United States Department Of The Interior, National Park Service

Parks and Reserves

To ensure maximum coordination of message delivery, personal service efforts should be orchestrated as a result of annual (winter season) planning sessions involving TW Services, Bryce/Zion Trail Rides, and park personnel. Such planning should coordinate general summer season schedules, brainstorm new program ideas and service proposals, and establish procedures for monitoring and evaluation. This is also an opportunity to identify high priority messages regarding resources, events, new services, and park management pertinent in the coming season; in this manner, emphases for seasonal training are established.

Pesticide Use And Toxicology In Relation To Wildlife: Organophosphorus And Carbamate , Compounds, Gregory J. Smith, U.S. Department Of The Interior, Fish And Wildlife Service

All U.S. Government Documents (Utah Regional Depository)

The use of organophosphorus and carbamate pesticides has increased markedly during the past two decades. Currently, more than 100 different organophosphorus and carbamate chemicals are registered as the active ingredients in thousands of different pesticide products in the United States. More than 160 million acre-treatments of these pesticides are estimated to be applied to agricultural crops and forests each year. Clearly, these two groups of chemicals constitute a major portion of all pesticides used today. Organophosphorus and carbamate compounds have histories dating back long before their use as pesticides. Carbamates were developed during investigation of "ordeal" poisons used in Africa …

Nitrogen Mineralization And Denitrification In Lake Michigan Sediment, Wayne S. Garder, Thomas F. Nalepa, John M. Malczyk

United States Department of Commerce: Staff Publications

Organic nitrogen mineralization mechanisms, fluxes, and fates in Lake Michigan sediments were examined by measuring accumulation rates of inorganic nitrogen in laboratory microcosms. Neither ammonium nor nitrate increased substantially in flow-cell or slurry microcosms of offshore, silty sediments. In experiments with gastight chambers containing "intact" offshore, silty sediment cores (sampled at 45- and 100-m water depths), the total fluxes of nitrogen (NH₄+, N0₃-, and N₂) across the sediment-water interface ranged from 14 to 51 µg-atoms N m^-2 h^-1. Nitrogen gas accounted for 93-98% of the total inorganic nitrogen flux from the …

Acceleration Of Nutrient Uptake By Phytoplankton In A Coastal Upwelling Ecosystem: A Modeling Analysis, Richard C. Zimmerman, James N. Kremer, Richard C. Dugdale

OES Faculty Publications

Studies of upwelling centers in the eastern Pacific suggest that maximum rates of nitrate uptake (light and nutrient saturated) increase, or shift-up, as newly upwelled water moves downstream. The rate of shift-up appears to be related to irradiance and the ambient concentration of limiting nutrient at the time of upwelling. A mathematical model was developed to evaluate effects of irradiance and initial nitrate concentration on temporal patterns of shift-up and subsequent time scales of nutrient utilization over a range of simulated upwelling conditions. When rates consistent with field studies were used, complete shift-up was possible only under certain conditions, and …

Interaction Of Long Waves And Nearshore Barred Topography--A Mechanism Of Bar Migration, Chang-Shik Kim

Dissertations, Theses, and Masters Projects

It has been widely observed in nature that longshore bar topography changes profile in the onshore-offshore direction. It is common for some bars to migrate onshore during post-storm phases and offshore during storms. Although the behavior of submarine bars has been widely reported, its mechanisms and forcings are far less clear. to determine the mechanism for bar migration or for the persistence of bar systems, a numerical model is developed, which accounts for the mass transport velocities in the bottom boundary layer induced by a family of combined long waves at surf-beat frequencies and wind waves. The present approach simulates …

Sorption Of Nonpolar Organics On Minerals And Aquifer Materials, Thomas B. Stauffer

Dissertations, Theses, and Masters Projects

The sorption of nonpolar organic chemicals on hydrous oxides, clay minerals, and subsurface aquifer materials was studied using the batch isotherm technique. Radiolabeled (&\sp{lcub}14{rcub}&C) trichloroethylene, orthodichlorobenzene, naphthalene, and 1-methylnaphthalene were sorbed on mineral sorbents, subsurface aquifer materials, and a surface soil at six different equilibrium concentrations over a concentration range from 0.001 mg/L to 1.0 mg/L. A knowledge of the sorption coefficients of these fuel components and solvents is necessary to predict the transport of these chemicals through groundwater systems and ultimately to rivers, lakes, and estuaries. Sorption on oxides and surface soils was found to be pH-dependent with decreased …

Dust Elimination From Outdoor Feedlots For Sheep, D J. Carter

Journal of the Department of Agriculture, Western Australia, Series 4

The humble woodchip, widwly used as a soil mulch in Western Australian gardens, is set tto take a new role as a dust inhibito in assembly yards used to hold live sheep for export.

Research by the Department of Agriculture's Soil Conservation Service Branch has shown that, of the materials tested, woodchips were the most effective in preventing dust being generated. Wind speeds had to approach a "near gale" before dust developedfrom the protected soil.

The use of woodchips, therefore, provides a practical alternative to stabalising the soil and preventing an environmental problem associated with one of the State's valuable …

Baseline Acidity Of Percipitation At The South Pole During The Last Two Millennia, J H. Cragin, M B. Giovinetto, A J. Gow

United States Army: Publications

Measurements of meltwater pH from annual layers of South Pole firn and ice samples ranging in age from 40 to 2000 years B .P. show that precipitation at this remote site has a higher natural acidity than that expected from atmospheric equilibrium with CO2. The average pH of deaerated (C O2-free)samples was 5 .64 + 0.08, while a irequilibrated samples averaged5 .37 + 0.08, a pH that is about a factor of two more acidic than the expected background pH of 5.65. The observed" excess" acidity can be accounted for by SO1-and NO7 levels in the samples originating from non-anthropogenic …

The Incorporation Of Environmental Perception Information Into Wilderness Park Safety Planning, Thomas Craig Waldichuk

Theses and Dissertations (Comprehensive)

The park safety planning process currently in use limits users’ inputs to accident statistics. It would be better to more accurately anticipate accident-prone locations and to take preventative measures. A planning methodology is proposed which integrates the safety perceptions of park users into the decision-making for locating facilities and services: the Recreation Opportunity Spectrum (ROS) serves as a systematic planning guide for such decision-making and is compatible with park policy and objectives. Applications to Garibaldi Provincial Park, British Columbia, and statistical and cartographic analyses of 273 questionnaires returned from there, indicate that park users’ perceptions can be advantageously incorporated into …

Oyster Spatfall In Virginia Rivers: 1986 Annual Summary, James Whitcomb
