State Effort In Controlling Oil Spills, Victor Alan Bell

Marine Affairs 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.

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.

The Arid Lands Revisited, 100 Years After John Wesley Powell, Thadis W. Box

Faculty Honor Lectures

presented his Report on the Arid Lands of the United States with a More Detailed Account of the Lands of Utah to Secretary of the Interior Carl Schurz. The report was not so much a careful scientific report, but a distillation of Powell's experiences in the arid regions and a compilation of his recommendations. The paper "was less a report than a program - even, some western congressmen would begin to say, a manifesto, a revolution" (Stegner 1962). Stegner wrote:

It would ultimately be recognized as one of the most important books ever written about the West, and it was …

The Impacts Of Agriculture And Pastoralism On Wildlife In The Sudan, Fraser Tong Kuotwel

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This report describes the effects of agriculture and pastoralism on wildlife resources in the Sudan. For centuries people in the western and southern Sudan have been earning their living through shifting cultivation and pastoralism. Being one of the agrarian countries of Africa, the Sudan is rapidly undergoing a transition from shifting cultivation to mechanized farming, in order to provide enough food for its rapidly growing human population, and to supply other Arab countries with the surplus. Mechanized farming and water associated development projects have great impact on wildlife resources, ranging from the destruction of wildlife habitat to the isolation of …

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 …

Rodent Density And Species Composition In The Snake River Birds Of Prey Natural Area, Idaho, Jon R. Montan Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rodent densities were estimated in the major vegetation types of the Snake River Birds of Prey Natural Area in 1975 and 1976 by a combination of live-trapping and kill-trapping. Only deer mice (Peromyscus maniculatus) were numerous enough to permit reliable density estimates. Relative densities of other rodent species were indicated by kill-trap capture rates. Densities of deer mice correlated well (r = 0.99) with kill-trap capture rates. The use of kill-trapping in place of live-trapping in 1976 permitted extensive sampling throughout the 1930 km² study area. Differences were found among the major vegetation and land-use types in …

Seasonal Course Of Root Respiration In Atriplex Confertifolia, Richard S. Holthausen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Root respiratory response of mature Atriplex confertifolia plants growing in established communities was measured during two growing seasons using freshly excised root segments and gas chromatography techniques. Respiratory response at fixed test temperatures changed significantly during the growing season, and this pattern of respiratory adjustment varied for root segments located at different depths in the soil profile. Respiration measured at a constant test temperature was highest during early sumner, and declined to minimum values in late summer and fall. Root segments taken from the top 30 cm of the soil profile displayed peak activity several weeks before root segments from …

The Effect Of Four Mine Spoil Treatments On The Seedling Water Relations Of Two Plant Species, Lorraine K. Van Kekerix

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Surface mines in mountainous areas cause environmental deterioration at lower elevations in the watershed. The most successful long term solution to the downstream problem is revegetation. However, mine spoils are low in essential plant nutrients, have low water holding capacity, and are often acidic. These factors limit plant colonization. Plants must also be adapted to the environmental conditions of high elevations.

At the McLaren Mine, }1ontana, at 2800 m, it was observed that seedlings on revegetation plots were desiccated, indicating possible water deficits. Field and growth chamber studies were carried out to determine the effects of some spoil ameliorating treatments …

Biological Manipulation Of Blackbrush (Coleogyne Ramosissima Torr.) By Browsing With Goats, Frederick D. Provenza

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to provide data on responses of Angora goats and blackbrush (Coleogyne ramosissima) to a biological manipulation program. Blackbrush utilization levels averaged 30, 16, and 6 percent (545, 367, and 147 kg per hectare) for the heavily, moderately, and lightly browsed pastures, respectively; removal rates of 77, 38, and 19 percent (1164, 582, and 291 kg per hectare) were projected.

Statistically significant differences in body weight loss (P=0.052) were noted for goats browsing in different replications. Goats lost an average of 14 and 19 percent of body weight in replications one and two, …

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 …

Contour Trenching As A Strategy In Watershed Rehabilitation: Application To Nepalese Condition, Kumar P. Upadhyay

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The disastrous soil erosion problems and the uncontrolled movement of water in Nepal's mountains caused by human and livestock activities call for the identification of simple, cheap, and effective rehabilitation techniques. This report analyzes contour trenching as rehabilitation techniques in the United States and examines the applicability and transferability of the techniques to the Nepalese conditions.

The details of contour trench systems as applied by the U. S. Forest Service have been analyzed by reviewing available research papers, handbooks, official records, personal communication, and actual field visits. The results and observations have been delineated for the physical and cultural aspects …

Surface Area Measurements And Seasonal Variation Of Selected New Mexico Lakes, Mike Edwin White

Geography ETDs

This research compares the ability of various areal measuring techniques to accurately measure reservoir surface area from Landsat imagery. Water volume and surface area data obtained from reservoir management agencies for six New Mexico reservoirs were used as test data. Acreage estimates obtained from a dot grid, an electronic planimeter, a 32-level color density slicer and a 16-level black and white density slicer, were compared to the test data. Surface area measurements were taken from Landsat infrared images by these devices at scales of 1:1,000,000, 1:500,000 and 1:250,000. The acreage estimates were obtained for four seasons during 1973. The results …

The Limnetic Zooplankton Community Of Boulder Basin, Lake Mead In Relation To The Metalimnetic Oxygen Minimum, Thomas A. Burke

Publications (WR)

The limnetic zooplankton community of Boulder Basin, Lake Mead, was examined to determine the role of this community in the development of a metalimnetic oxygen minimum which regularly occurs in the lake. Analysis of the community from May 1975 to April 1976 revealed that zooplankton maintain high populations within the metalimnion during summer stratification. The species composition of the community changes noticeably during the summer, but due to advanced stages excysting from resting forms, a complete assemblage of individuals are found throughout the 74 day period studied. Thermal stratification was weak, covering a 30 meter metalimnion. Eddy currents powered by …

An Epornitic Of Avian Cholera In Waterfowl And Common Crows In Phelps County, Nebraska, In The Spring, 1975, Joseph Zinkl, Norm Dey, Joseph Hyland, James Hurt, Kenneth Heddleston

Nebraska Game and Parks Commission: Staff Research Publications

In the spring of 1975, many species of waterfowl and common crows (Corvus brachyrhynchos) were found dead in Phelps County, Nebraska. About 25,000 waterfowl and at least 3,000 crows died in the epornitic. Few waterfowl were seen dying, but the crows experienced a chronic illness during which they became debilitated and were lethargic and dyspneic. Gross and microscopic lesions in the waterfowl were typical for acute avian cholera. The crows had dank, firm areas within the lungs, a loosely adhered yellow fibrous material in the pericardial sac and air sacs and, occasionally, liver abscesses. Microscopically, focal punulent pneumonia …

Aspergillosis In Common Crows In Nebraska, 1974, Joseph Zinkl, Joseph Hyland, James Hurt

Nebraska Game and Parks Commission: Staff Research Publications

During fall 1974, approximately 1,000 to 1,500 common crows (Corvus brachynhvnchos) died of aspergillosis in south-central Nebraska. The binds were debilitated, lethargic and dyspneic. On necropsy, typical lesions of aspergillosis were found in the lungs and air sacs. Histopathologic examination revealed granulomatous lesions around fungal hyphae in the respiratory system.

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

Marine Affairs 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

Marine Affairs 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 …

Rhode Island Coastal Zone Management And Local Government Organizational Structure: An Analysis Of Selected Community Governments, Methods, And Capabilities, Robert F. Greene

Marine Affairs Theses and Major Papers

It is the purpose of this discussion to examine the organizational structure, and the governmental processes selected Rhode Island communities utilize to carry out their particular role as participants in the management of the coastal resources within their political boundaries. Insofar as practicable, the major sources of information for this research are the communities themselves--their elected and appointed officials, and the documentary material the Towns generate and use as they carry out their management functions.
