Temporal And Spatial Patterns Of Abundance Of Age 0 Threadfin Shad (Dorosoma Petenense) In Overton Arm, Lake Mead, William Lee Pelle

Publications (WR)

Temporal and spatial patterns of age 0 threadfin shad (Dorosoma petenense) abundance and growth, in the Overton Arm of Lake Mead, were examined to evaluate the effects of resource availability on the young fish. This was part of a larger, game fishery enhancement study (Lake Mead Fertilization Project), designed to assess feasability of increasing survivorship of larval/juvenile shad by boosting phosphate levels, thereby increasing algal and zooplankton biomass, during the shad spawning period. Shad are the primary forage base for the striped bass (Morone saxatilis) and black bass (Macropterus salmoides) fisheries. Weekly samples were …

Red Swamp Crayfish Ecology In Lake Mead, Suzanne E. Leavitt, Jennifer Stephens Haley, Mikell Hager, Donald H. Baepler, Nevada Department Of Wildlife

Publications (WR)

Red swamp crayfish (Procambarus clarkii) were trapped in Flamingo Wash, an urban wash of Las Vegas, during four periods of 1988. Life history and reproductive success were determined. The trapped crayfish were marked and released into a study cove in Lake Mead as part of an experimental stocking program. Retrap data from the study cove were used to determine life history, habitat preferences, and movement patterns of the stocked crayfish. In addition, a literature search was done on red swamp crayfish ecology, including food preferences, life history, habitat preferences and fish predation.

Environmental Management Planning And The Special Area Management Process, Timothy P. Dillingham

Marine Affairs Theses and Major Papers

Within coastal areas, growing numbers of resource users, increasingly divergent resources use demands, and loss of indigenous resources combine to exert tremendous pressures on these areas. The Narrow River is a unique estuary located on the coast of southern Rhode Island. The estuary has experienced a decline in water quality over the last 20 years, primarily attributable to poor development practices and improper disposal of on-site sewage. Increasing levels of development have begun to bring about further changes in the watershed, including alteration of scenic values, conversion and loss of wildlife habitat, additional sources of pollution inputs and increasing conflict …

A Site-Specific Need Assessment For Ocean Incineration At The North Atlantic Incineration Site (Nais), Lynne H. Macdonald

Marine Affairs Theses and Major Papers

This thesis examines the problems of hazardous wastes in the United States-and the problems their disposal present, in particular. Ocean incineration, one of the very few methods available to destroy many highly toxic wastes, is presented as a viable, necessary means to destroy liquid organochlorine wastes. Next, the international and federal regulations governing ocean incineration and the current status of ocean incineration in the United States are reviewed. A site-specific assessment for determining the need for ocean incineration is developed as an alternative to the two currently contended approaches (nationwide versus permit-by-permit need assessments). This site-specific need assessment evaluates the …

Intergovernmental Relations And Ocs Oil And Gas Development, Gretchen Honan

Marine Affairs Theses and Major Papers

Oil and gas exploration and development in federal waters off the coast of California have been a source of conflict between federal and state governments for a number of years. More recently local governments and local citizenry have joined in the battle to prevent development of outer continental shelf (OCS) oil and gas reserves. Between 1985 and 1986 the passage of thirteen local land use initiatives prohibiting or requiring voter approval of onshore facilities to service offshore platforms occurred. These initiatives reflect growing local dissatisfaction with the present legislative structure governing OCS development. From their perspective the existing OCS development …

Formulation Of A Management Scheme For The Swordfish Fishery Of The Eastern Caribbean, Harold F. Upton

Marine Affairs Theses and Major Papers

During the 1983 season, two U.S. longline vessels initiated the first attempts at the commercial exploitation of swordfish in the Eastern Caribbean. In 1986, the number of U.S. vessels participating in the fishery surpassed 40 with landings of nearly two million pounds per season. The sudden influx of participants and technology to the region has resulted in a variety of user conflicts and associated policy issues. Major areas of concern involve the conservation of a heavily exploited resource and the distribution of benefits which accrue from resource exploitation among the resource-adjacent island states and U.S. fishing operations. This study examines …

Stormwater Quality Management In Rhode Island, Elizabeth A. Scott

Marine Affairs Theses and Major Papers

This study documents the threat that uncontrolled "urban" stormwater runoff poses to surface water quality and the inadequacy of existing regulations governing land use development in preventing further water quality degradation resulting from "urban" runoff. The study applies recent research findings from the Nationwide Urban Runoff Program and the experience of other state regulatory programs in evaluating management alternatives and proposing a strategy for Rhode Island. The documented impacts of "urban" stormwater runoff on water quality, including excesses in criteria for copper, lead, and coliform, and eutrophication, support the need for stormwater quality management. This need is made more evident …

Sewage Discharge By Recreational Boats In R.I. Coastal Waters, Maureen E. Eldredge

Marine Affairs Theses and Major Papers

Federal legislation regulating sewage from recreational boats has existed since 1972 (The Clean Water Act). Since that time the regulations have failed to prevent untreated sewage from boats from being discharged into the Nation's waterways. This has caused conflicts over water quality, particularly in shellfish growing areas. The regulatory system which exists to regulate sewage from recreational boats was analyzed for nine sources of possible regulatory failure. Seven of the nine were found to be operating. They include, lack of technology, lack of enforcement, lack of issue salience, negative attitudes on the part of the boaters, the economics of compliance, …

Antarctic Peninsula Mysticete Whales: Conservation And Research, Gregory Schofield Stone

Marine Affairs Theses and Major Papers

This paper reports original research from two recent studies in the Antarctic Peninsula area, reviews past sighting information and policies affecting mysticete whales, and recommends future research. Due to poor management by the International Whaling Commission, mysticete whales are among the most severely depleted species groups in the Antarctic. The combined total Antarctic harvest from 1920 to 19867 for blue Balaenoptera musculus, fin B. physalus, sei B. borealis, minke B. acutorostrata and humpback Megaptera novaeangliae whales was over one million animals. The effect of this hunting pressure is the dominant factor determing the present status of Antarctic …

North Carolina Ports: A Search For Identity, Clifford S. Sharpe

Marine Affairs Theses and Major Papers

North Carolina's development in colonial times and in the early stages of statehood was greatly affected by her coastline. An abundant coastline did not translate into an abundance of good ports, in fact, difficult coastal and inland navigation hampered early commercial development. North Carolina's barrier islands and numerous inlets served as a haven for pirates in colonial days, for privateers during the Revolution, and later defied the North's blockade during the Civil War. There were several attempts by individuals to encourage maritime trade in the late nineteenth and early twentieth century. Shortly after World War II the state mobilized to …

The paper will provide a background by addressing the recent history, status and current missions of the Soviet Navy, which is the vehicle for maritime power. The nature of the geographical constraints will then be discussed before assessing individually the impacts on the four Soviet Fleets: Northern, Baltic, Black Sea, and Pacific. Finally, some alternatives will be explored to counter the vulnerability of maritime power to those geographic constraints. It …

Riparian Plant Water Relations Along The North Fork Of The Kings River, California, J. L. Nachlinger, S. D. Smith, R. J. Risser

Life Sciences Faculty Research

Plant water relations of five obligate ripar-ian species were studied along California's North Fork Kings River. Diurnal stomatal conductance, transpi-ration, and xylem pressure potentials were measured throughout the 1986 growing season and in mid-season in 1987. Patterns were similar for all species although absolute values varied considerably. Maximum stomatal conductance occurred early in the day and season during favorable environmental conditions and decreased as air temperature and the vapor pressure difference between the leaf and air increased. Maximum transpiration rates occurred in mid-morning and mid-summer resulting in estimated daily water losses per unit sunlit leaf area of 163-328 mol H2O …

An Isotopic Analysis Of The Hydrology And Riparian Vegetation Water Sources On Bishop Creek, M. L. Space, J. W. Hess, S. D. Smith

Life Sciences Faculty Research

Five power generation plants along an eleven kilometer stretch divert Bishop Creek water for hydro-electric power. Stream diversion may be adversely affecting the riparian vegetation. Stable isotopic analysis is employed to determine surface water/ground-water interactions along the creek. surface water originates primarily from three headwater lakes. Discharge into Bishop Creek below the headwaters is primarily derived from ground water. The average δD and δ18O values are significantly different for surface water and ground water that an isotopic analysis can delineate between these two components of flow. Therefore isotopic shifts along the creek can determine gaining reaches. In addition, by knowing …

Executive Summary

Biological diversity refers to the variety and variability among living organisms and the ecological complexes in which they occur. Diversity can be defined as the number of different items and their relative frequency. For biological diversity, these items are organized at many levels, ranging from complete ecosystems to the chemical structures that are the molecular basis of heredity. Thus, the term encompasses different ecosystems, species, genes, and their relative abundance (OTA, 1987).

There is an ongoing, unprecedented loss of the variety as well as absolute numbers of organisms-from the smallest microorganism to the largest and most spectacular of …

The Uranium-Trend Dating Method: Principles And Application For Southern California Marine Terrace Deposits, Daniel R. Muhs, John N. Rosholt, Charles L. Bush

United States Geological Survey: Staff Publications

Uranium-trend dating is an open-system method for age estimation of Quaternary sediments, using disequilibrium in the ²³⁸U–²³⁴U–²³⁰Th decay series. The technique has been applied to alluvium, colluvium, loess, till, and marine sediments, in this study we tested the U-trend dating method on calcareous marine terrace deposits from the Palos Verdes Hills and San Nicolas Island, California. Independent age estimates indicate that terraces in these areas range from –80 ka to greater than 1.0 Ma. Two low terraces on San Nicolas Island yielded U-trend plots that have a clustered array of points and the ages of …

Temporal And Spatial Variation In Pelagic Fish Abundance In Lake Mead Determined From Echograms, Gene R. Wilde, Larry J. Paulson

Publications (WR)

Echograms have been used extensively to locate and estimate the relative abundance of marine fish stocks (Cushing 1973). In freshwater, echograms have been used to describe vertical (Netsch et al. 1971; Eggers 1978; O'Brien et al. 1984; Matthews et al. 1985), spatial (O'Brien et al. 1984; Wanjala et al. 1986) and temporal (Baker and Paulson 1983) patterns in fish abundance. Although most uses of echograms have been qualitative, Mullan and Applegate (1969) and Matthews et al. (1985) obtained relative estimates of fish abundance by counting targets (fish) on echograms. However, neither Mullan and Applegate (1969) nor Matthews et al. (1985) …

The Effect On Earth's Surface-Temperature From Variations In Rotations Rate, Continent Formation, Solar Luminosity, And Carbon Dioxide, William R. Kuhn, J. C.G. Walker, Harold G. Marshall

Biological Sciences Faculty Publications

Proposed evolutionary histories of solar luminosity, atmospheric carbon dioxide amounts, Earth rotation rate, and continent formation have been used to generate a time evolution of Earth's surface temperature. While speculative because of uncertainties in the input parameters, such a study does help to prioritize the areas of most concern to paleoclimatic research while illustrating the relationships and mutual dependencies. The mean temperature averages about 5 K higher than today over most of geologic time; the overall variation is less than 15 K. The evolution of Earth's rotation rate makes a significant contribution to the surface temperature distribution as late as …

Survival Of Trout Strains As Affected By Limnological Parameters, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

Prior work at East Canyon Reservoir, Utah indicated that adult trout are important predators of stocked juvenile rainbow trout. Brown trout, in particular, were exclusively piscivorous when th~y exceeded 185 mm standard length. Fish became increasingly important in the diet of cutthroat trout greater than 330 mm. The purpose of this study was to further document the effect of adult trout on survival of juvenile rainbow trout in mid-elevation reservoirs. Causey Reservoir was chosen because it was thought to contain large brown and cutthroat trout and had not been intensively studied during the last eight years.

It provides research and extension services to the pastoral industry, provides advice on the condition of the range resource to Government and provides technical information on rangelands to other rangeland managers. A principal objective to be met in fulfilling that role is the development and promotion of economically efficient place systems that conserve the rangeland resource. At the inaugural Pastoral Soil Conservation Districts Conference in Meekatharra in May 1987, pastoralist delegates emphasized the importance of achieving that objective within the various soil …

Estimating Potential Ground And Surface Water Pollution From Land Application Of Poultry Litter - Ii, D. C. Wolf, J. T. Gilmour, P. M. Gale

Arkansas Water Resources Center Technical Reports

In Arkansas, approximately 1 Tg of poultry (Gallus gallus domesticus) manure and litter is produced annually. These waste products are commonly applied to pastures as a soil amendment or fertilizer, but excessive application rates and poor management practices could result in nutrient contamination of ground and surface water. The purpose of this study was to: (1) assess the nutrient concentrations in poultry manure and (2) evaluate the nitrogen loss from land-applied poultry litter and manure due to ammonia volatilization and denitrification. Analyses for total Kjeldahl nitrogen (TKN), inorganic nitrogen (Ni), phosphorus (P), and potassium (K) were compared in 12 wet …
