Limnological Aspects Of Lake Mead, Nevada-Arizona, John R. Baker, James E. Deacon, Thomas A. Burke, Samuel S. Egdorf, Larry J. Paulson, Richard W. Tew, Bureau Of Reclamation

Publications (WR)

Lake Mead is a deep, subtropical, moderately productive, desert impoundment with a negative heterograde oxygen profile occurring during; the summer stratification. investigations of the Boulder Basin of Lake Mead by the University of Nevada were initiated in November 1971. The primary objective of the study was to determine what effects industrial and sewage effluent from the Las Vegas metropolitan area, discharged into Las Vegas Bay, have had on the water quality and limnological conditions of Boulder Basin. Data from the 1975-76 period are presented in detail, with earlier data included in the summaries and discussions.

State Effort In Controlling Oil Spills, Victor Alan Bell

Theses and Major Papers

In light of the growing demand for imported oil, the accelerated offshore development program and the recent series of tanker incidents, many states have enacted, or plan to enact, legislation to protect their coastal lands and waters from oil pollution. The purpose of this paper is to outline present state legislation that deals with controlling oil pollution, and stating how this legislation would coexist with existing and proposed federal legislation and the International Conventions. The results of this study point to areas where state legislation would be useful and where overlapping or unnecessary legislation does exist.

Coyote-Food Base Relationships In Jackson Hole, Wyoming, John L. Weaver

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I measured three variables of coyote-food base relationships in Jackson Hole, Wyoming, during the period July, 1973, to July, 1975. Field work provided estimates of relative coyote and prey abundance as well as observations on coyote feeding behavior during winter. Laboratory analysis of 1,500 coyote scats revealed feeding patterns while feeding trials with captive coyotes allowed refinement in interpretation of scat analysis.

Deer mice and chipmunks comprised most of the rodent biomass captured in traps in the fall, while ground squirrels accounted for much of the rodent biomass in the spring. Field voles declined from 1973 to 1974 throughout much …

Preliminary Report On A Pleistocene Pond, Garden County, Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Discontinuous Pleistocene pond deposits occur along the valley sides of Dankworth Canyon southeast of Lewellen, Nebraska. At one locality the beds exposed in a channel-fill up to six feet thick consist of sand-sized carbonate-rich sediments deposited in alter nating light and dark layers resembling varves. Microscopic examination of disaggregated samples reveals that most of the sediment consists of sand and silt often cemented into tubes. Other components include several kinds of freshwater ostracodes, gastropods, charophyte gyrogonites, and bone-like debris probably from fish.

Evaluation Of Some Soil Loss Equations For Predicting Sheet Erosion, Douglas Joseph Trieste

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objectives of this study were (a) to apply sediment and associated plot data from various infiltrometer studies to the parameters in the Universal Soil Loss Equation, a modified version of the original Musgrave Equation, and a modified version of the original Universal Soil Loss Equation, and compare the computed results with the measured soil loss, (b) to suggest reasons for any differences between computed and measured soil loss, and (c) to suggest improvements for each equation so that it will give results near the measured soil loss. The data used consisted of 2805 infiltrometer plots collected by previous researchers …

West Africa (East Central Atlantic) As A Regional Base For Fisheries Management, Conservation And Research: And Pollution Control, Vincent F. Adebolu

Theses and Major Papers

About two decades ago when the First Law of the Sea Conference was underway, little attention was paid to ocean management. By then all of the ocean space apart from narrow bands of coastal waters was broadly recognized as the High Seas which is open to use by all countries. But despite this concept of free open use, only the major maritime powers were actually interested in maximizing the freedom of the seas principle. During this period there were only ninety independent coastal and landlocked states.

A Study Of The Second And Third Committees Of The Third United Nations Conference On The Law Of The Sea, James C. Bridgman

Theses and Major Papers

The Third United Nations Conference on the Law of the Sea was divided along lines established for the preparitory Conference. The plenary consisted of all delegates of all delegations and was generally used to make formal what had already been negotiated in closed sessions. In the fifth session, it took on a new function as a forum for debating in closed session proposed articles on dispute settlement. In the future, it will look at drafts of the preamble and final clauses to the Convention. Each of three primary committees was empowered with specific issues to consider, again stemming from the …

Biota Of Lake Mead: Annotated Checklist And Bibliography, Wesley E. Niles, Charles L. Douglas, National Park Service

Publications (WR)

In 1935 construction was completed on the Bureau of Reclamation's Hoover Dam, located near the bend of the historic Colorado River. Rising 726 feet within the rugged walls of Black Canyon, the structure is still recognized today as the highest concrete dam in the western hemisphere. Impoundment of water above Hoover Dam created Lake Mead, some 110 miles long, having a shoreline of 84 miles when the lake is at its maximum elevation of 1229 feet - this country's largest man-made reservoir. Below the dam, in Black Canyon and southward, the wild aspect of the Colorado River was altered by …

Daily Maximum And Minimum Temperature Forecasts And The Influence Of Snow Cover, Kenneth F. Dewey

School of Natural Resources: Faculty Publications

Research into the relationship between snow cover and observed maximum and minimum temperatures is reviewed. An example of the importance of snow cover and forecasting max/min temperatures is presented for this past winter (1976-77). It is shown that there was a warm bias in the MOS temperature forecasts for the northern Great Plains following the receipt of a fresh cover of snowfall. it is proposed that snow cover be incorporated as a conditional predictor to be used only during specific synoptic conditions.

Occurrence Of Four Major Perennial Grasses In Relation To Edaphic Factors In A Pristine Community, Edgar F. Kleiner, K. T. Harper

Canyonlands Research Bibliography

The ecology and phytosociology of a virgin grassland community (Virginia Park, Canyonlands National Park, Utah) have been investigated. Based on the use of C √ó F index, Hilaria jamesii and Stipa comata are the most abundant of the four major perennial grasses. Oryzopsis hymenoides and Sporobolus cryptandrus are less abundant in decreasing order. The sites dominated by Hilaria are characterized by soils with finer texture, slightly warmer average temperature and higher surface K+ and organic matter compared to sites dominated by Stipa comata. In addition, frequency of both vascular and cryptogamic species is greater on sites dominated by Hilaria.

Soil Properties In Relation To Cryptogamic Groundcover In Canyonlands National Park, Edgar F. Kleiner, K. T. Harper

Canyonlands Research Bibliography

A comparative study was made of the soils of a virgin grassland and an adjacent grazed area in Canyonlands National Park. Soils from the virgin site were finer textured than those of the grazed area, and the surface 5 cm contains a significantly lower amount of calcium. In addition, the surface 5 cm of the virgin site contains significantly greater amounts of phosphorus, potassium, and organic matter. Subsurface soils in the two parks are less dissimilar. Cryptogams on the virgin grassland appear to have an important influence on chemical characteristics of the surface 5 cm of soil. The difference in …

The Florida Coastal Zone Management Program: What, Why, How, Who., Florida Bureau Of Coastal Zone Planning, State Of Florida, Dept. Of Environmental Regulation, Division Of Environmental Programs, Bureau Of Coastal Zone Planning

Waterways and wildlife

A Florida coastal zone management program, once approved and established, will be a cooperative effort of all levels of government and the citizens of Florida. It will establish coastal land and water resource policies, based on realistic goals and objectives, that contribute to the wise use of those resources and protect the options of future generations. It will be a system that is sensitive to criticism, accessible to review and appeal, and flexible enough to reflect changing goals, needs, attitudes and lifestyles. With this approach we can not only treat current problems, but can also avoid future resource use conflicts. …

Biology Of The Porcupine (Erethizon Dorsatum) In Northwestern South Dakota, Judith Johnson

Electronic Theses and Dissertations

The summer home ranges, food habits, cover preferences, population dynamics, metabolic rates, growth rates, and taxonomic characteristics were determined for porcupines (Erethizon dorsatum) in northwestern South Dakota. The summer home ranges were 158.2 ha for adult females, 90.4 ha for juveniles, and 57.9 ha for adult males. The population was 34 percent adult males, 16 percent juvenile males, 34 percent adult females, and 15 percent juvenile females. The preferred daytime cover choice was silver buffaloberry (Shepherdia argentea), followed by snowberry (Symphoricarpos occidentalis), earth dens, forbs, and low brush. Shrubs were the most important item in the diet, then trees, forbs, …

Factors Affecting Waterfowl Brood Use Of Stock Ponds In South Dakota, Gene D. Mack

Electronic Theses and Dissertations

A July waterfowl brood survey was conducted from 1973 to 1976 on stock ponds located within four physiographic strata in South Dakota. Information was collected on weather, stock pond characteristics, land use and the condition of other wetlands located within the quarter section (64.8 ha) study plots. Multiple regression and multiple discriminant analyses were sued to determine the importance of these variables in influencing brood use of stock ponds. Vegetation type, distribution of emergent vegetation and pond size were important in determining if broods of any particular species utilized a pond or not. Shoreline distance was particularly important in explaining …

Variables Associated With Breeding Waterfowl On South Dakota Stock Ponds, Jay A. Roberson

Electronic Theses and Dissertations

Use of stock watering ponds by indicated breeding pairs of waterfowl was measured in the western two-thirds of South Dakota from 1973 to 1976. Multiple regression and discriminant analyses were used to describe the habitat associated with pairs of each species. Habitat variables explained 35-47 percent of the variation in pairs having small home ranges and 26-35 percent of the variation in pairs having large home ranges. Shoreline distance account for more variation in mallard (Anas Platyrhmchos) and blue-winged teal (A. discors) pairs than any other single variable. Ponds used by these pairs and shoreline distances that averaged 590 m …

Estimate Of Production By A Population Of Fathead Minnows, Pimpephales Promelas, In A South Dakota Prairie Wetland, Ronald D. Payer

Electronic Theses and Dissertations

Estimates of production and population densities were obtained for an autochthonous population of fathead minnows, Pimephales promelas Rafinesque, in a South Dakota prairie wetland. The study was conducted from May to September of 1976. Population estimates were obtained using a Schnabel-type mark and recapture model. Fish were marked either by fin clipping or granular fluorescent pigments driven into the dermal tissue. Production estimates were derived both arithmetically and graphically. The estimated population of adult fathead minnows declined from 194 in May and June to 26 in July. Production by adults was estimated at 0.10 kg, or 0.0007 gm/m²/yr. The population …

Cover Use And Activity Time Budget Of Blue-Winged Teal, Mallard, And Pintail Broods, James K. Ringelman

Electronic Theses and Dissertations

Blue-winged teal (Anas discors), mallard (A. platyrhynchos), and pintail (A. acuta) broods were observed on 17 days between 25 June and 30 July, 1976. Brood activities and cover uses were recorded continuously from first light until dark. Observations of 269 broods from three wetlands were evaluated by species and brood age-class. Activity time budgets revealed significant (p<.01) age specific differences in total feeding time and visibility among age-classes of all species combined and age-classes of blue-winged teal broods. Feeding modes also varied among age-classes. Daily patterns of cover use varied among brood age-classes and species. Morning and evening feeding peaks became more pronounced, and overall visibility increased, with brood age. Interspecific differences in daily activity patterns were observed among broods of the same age-class. Duration of active periods increased with age in blue-winged teal broods. Active periods recurred at regular intervals in all broods throughout the day, suggestive of polycyclic behavior patterns similar to those of adult ducks. A progressive increase in brood visibility was attributed primarily to seasonal changes in brood age structure and to wetland water loss. Temperature and wind speed influenced brood visibility during most observation days. Climatic conditions favorable to nighttime brood activity influenced brood behavior during the following day. Accuracy of present brood inventory techniques could be improved if considerations were made for brood behavior patterns and environmental factors which alter brood cover use.
