Removal Of Chloroform From Drinking Water, John S. Zogorski, George D. Allgeier, Robert Lee Mullins Jr.

KWRRI Research Reports

The overall objective of this investigation was to evaluate via laboratory experiments the technical feasibility of reducing trihalomethane levels in drinking water. Special attention was directed at the removal of chloroform since: (a) it is the only trihalomethane which has been shown to be carcinogenic in animal tests; and (b) this compound generally comprises the largest fraction of the total trihalomethane content of chlorinated waters in Kentucky. Trihalomethanes are present in municipal drinking waters due to the reaction of free chlorine with naturally occurring compounds, collectively called "precursors".

A variety of treatment processes and potential modifications (or additions) to existing …

Dredge Spoil Disposal With Particular Reference To Management Practices In Southern New England, Lynne A. Melville

Marine Affairs Theses and Major Papers

One-half million acres of U.S. coastal wetlands have been destroyed by dredging and filling operations since 1956. They are being destroyed at the rate of 0.5-1.0% each year. In one ten year period, Rhode Island lost 5% of its 2000 acres of wetlands to urban development, and Connecticut lost 12% of its marsh lands. Less than 1500 acres of marsh remain in Connecticut. During the course of this research project, I examined one aspect of wetland destruction - the dredging and disposal of spoil materials onto wetlands and into the coastal waters of Southern New England. What follows is a …

A Discriminant Function Model Of Gray-Headed Junco Habitat, Andrew R. Grainger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper presents a description of gray-headed junco habitat in the form of a model based on discriminant function analysis. Junco nests were found by searching randomly located grids on a 7.8 km² study area in central Utah. Vegetation data was gathered on 500 m² circular plots surrounding nests and contrasted with similar data from searched grids where nests were not found. The model explains 28 percent of the between-groups variance and correctly classifies 68 percent of the plots.

Plant cover types are good predictors of areas where gray-headed juncos nest, while plant community type descriptions do not …

Plant Succession Studies On Subalpine Acid Mine Spoils In The Beartooth Mountains, Patricia Lea Howard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Large areas within alpine and subalpine tundra have been by disturbed by mining during this century. The most promising method for retarding deterioration of these areas is revegetation with native species through both seeding and transplants. One natural process of revegetation which occurs on portions of many existing disturbances seems to be the establishment of a few species that expand with time to form matts of plants.

At the McLaren Mine, located at 3000 m elevation in the Beartooth Mountains, Montana, active succession is occurring and is dominated by Carex species. Seed viability and successional patterns studies were conducted on …

The Effect Of Selenium On The Toxicity Of Methyl Mercury In Medaka Embryos, Peter H. Krauth

All-Inclusive List of Electronic Theses and Dissertations

The purpose of this research was to investigate the effect of selenium upon methyl mercury poisoning in Medaka fish (Oryzias latipes) embryos. Selenium has been shown to provide a protective mechanism against mercury poisoning in some adult animals. Three experiments were done. In the first, selenium and methyl mercury were put directly in the growing medium of the eggs. In the second experiment, selenium was included in the diet of the parent fish. In the third part, methyl mercury exposure was delayed three days. The results of the first experiment were quite dramatic and showed a significant difference when selenium …

Organochlorine Pesticide Residue, Physico-Chemical, And Bacteriological Profile Of The Lower Rio Grande River Of Texas, Juan H. Gonzalez

Theses and Dissertations - UTB/UTPA

An investigation was conducted to determine if the widespread and abundant use of organochlorine pesticides in the Lower Rio Grande Valley of Texas has had any effect on the microbial flora in the water and in the bottom sediments of the Lower Rio Grande River of Texas.

Rio Grande River water and bottom sediments were cultured for microbial flora, were analyzed for pesticide residues, and the physicochemical properties of the water were determined. Samples were taken at four different sites during a ten month sampling period in 1974.

Traces of organochlorine residues were found in the water, and higher concentrations …

An Input-Output Analysis Of The Soviet Fleet In Icnaf Areas 5 And 6, 1961-1973, F. Robert Bauer

Marine Affairs Theses and Major Papers

One of the goals of the Fishery Conservation and Management Act of 1976 was the rebuilding of the American fishing industry. However, the Act does not give the U.S.fisherman exclusive rights to the fishery resource. The American fisherman will still be competing with the foreign fleets. Section 204 (b) (1) of the Fishery Conservation and Management Act of 1976. states: Each foreign nation with which the United States has entered into a governing international agreement shall submit an application to the Secretary of State each year for a permit for each of its fishing vessels to engage in fishing described …

Present Trends In The Development Of Marine Fisheries By Coastal States Of The East Central Atlantic, Ethman T. A. Golley-Morgan

Marine Affairs Theses and Major Papers

In order to create an incentive for a rapid development of the rural-based artisanal fisheries of coastal states, that can actively compete with large scale industrial fisheries of non-coastal states as well as coastal states of the region, some states are now moving towards an integrated approach in their development efforts. Such integrated projects will take into consideration rural development, provision of infrastructural facilities for fish handling and processing, vessel servicing, repairs and boat building. Socio-economic factors such as organization of fishermen's cooperatives, financing and marketing institutions are also vital inputs.

Conflict In Outdoor Recreation, Gerald R. Jacob

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The causes of conflict among users of outdoor recreation resources have received little attention from recreation researchers. Knowledge of factors responsible for conflict might assist recreation planners' attempts to reduce future instances of conflict and help management focus its conflict resolution efforts. A theory of conflict is offered as the first step in systematically procuring such knowledge. A definition and characteristics of outdoor recreation conflicts are presented; four comprehensive causes of user conflicts are proposed. Ten propositions are used to link these factors to conflict and suggest future research hypotheses. The social psychological dynamics of conflict, as described here, have …

Adaptive Significance Of Lactate Dehydrogenase B2 Isozymes In Rainbow Trout, Salmo Gairdneri And A Biochemical Genetic Comparison Of Cutthroat Trout (Salmo Clarki) Populations, Gerald Thomas Klar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rainbow trout lactate dehydrogenase (LDH) B²' B²' , B²' B²" and B²" B²" phenotypes were tested under a variety of conditions for swimming endurance, oxygen consumption rates, and blood pH, pO₂, and lactate. The B²" B²" phenotype exhibited a lower swimming endurance, under a limited oxygen supply, than the B²' B²' and B²' B²" phenotypes. Blood pH at fatigue did not differ among the LOH phenotypes that swam under low oxygen conditions (2 mg/1). …

Park Visitor Responses To Natural Hazards, Lee H. Rentz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Natural hazards have been an increasing problem in wildland recreation areas. This study attempted to identify factors affecting park visitor perception of and preparedness for hazards.

A model was formulated incorporating three major independent variables which might affect park visitor responses to hazards. These were: (1) previous experience, (2) information about hazards provided by the park administration (such as warnings located on signs or in brochures), and (3) visitor perception of whether responsibility for hazards rests with the individual or with an outside authority such as government or God. Trip length and knowledge of hazards were also thought to be …

Physiological Response To Hooking Stress In Largemouth Bass (Micropterus Salmoides), A. Wayne Gustaveson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recent concern about large initial and delayed mortalities resulting from tournament angling for largemouth bass has indicated that it would be desirable to further evaluate the fate of fish that are released after being captured by angling. This study was designed to evaluate sublethal physiological disruptions caused by hooking stress after largemouth bass were played under standardized conditions (0-5 minutes) and to estimate the time needed for recovery of the homeostatic mechanisms (to 72 hours). Blood lactate was used as a measure of metabolic fatigue; plasma osmolality and chloride measurements were used to evaluate osmoregulatory disturbances and gill ion-exchange; and …

Population Dynamics And Net Production Of Brown Trout (Salmo Trutta) In Two Areas Of A High Gradient Mountain Stream, Jeffrey C. Gosse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Estimates of the brown trout (Salmo trutta) population were made in two areas of the Blacksmith Fork River, Cache County, Utah, from June 1972 to June 1973. Additional data were obtained on movement, growth, mortality, biomass, production, and yield.

Population density was highly variable in the area where habitat alterations had occurred, but was relatively uniform where the habitat was undisturbed. The brown trout exhibited little movement except during spawning season. Instantaneous growth and mortality rates are provided for each age group.

Mean annual biomass in the two areas was 12.0 and 10.2 grams per square meter and …

Conservation According To The Pure Theory Of Exhaustible Resources, George Lymbouris

Economics Theses & Dissertations

The objective of this thesis is to develop a theory for defining optimal conservation and applying definition to the prevailing rate of domestic petroleum production. Optimal conservation is defined as action designed to achieve or to maintain, from the point of view of society as a whole, the maximum present value of natural resources (or of a natural resource). The proper "action" is defined according to the pure theory of exhaustible resources. The literature survey is a chronological series of articles concerning this theory.

Through building a model which shows that optimal conservation occurs when the marginal internal rate of …

The Rush Creek Structure, Garden County, Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Detailed field mapping of surface outcrops in southern Garden County, Nebraska, has revealed a drop of 200 feet in three miles in the elevation of the contact between the Ogallala and pre-Ogallala (probably Brule) Formations exposed on the east side of Rush Creek. Beds of silt, sand, siltstone, and volcanic ash in the are a locally dip to the northwest at angles of up to 8½°. The contact between the two formations cannot be seen on the west side of Rush Creek but beds in the Ogallala Formation there dip to the north and northeast. The unusually long valley of …

Microhabitat Selection In Two Species Of Heteromyid Rodents, Cliff A. Lemen, Michael L. Rosenzweig

School of Natural Resources: Faculty Publications

An experiment was conducted to determine the microhabitat preferences of two heteromyid rodents, Dipodomys ordi and Perognathus flavus. This experiment used marked seeds and the atomic absorption spectrophotometer in order to study the environment as a mosaic of microhabitats. The results of our analysis indicate that these two heteromyids are microhabitat selectors. The preferences of the rodents are, D. ordi: grass habitat 0.0%, near grass habitat 22.5%, open habitat 77.4%, and P. flavus: grass habitat 46.2%, near grass habitat 32.2%, open habitat 21.4%. The overlap between the two species is only 0.43.

Seed Size Selection In Heteromyids: A Second Look, Cliff A. Lemen

School of Natural Resources: Faculty Publications

The general conclusion of this paper is that heteromyids do not select seed sizes on the basis of their body size. My conclusion comes from the analysis of new data from central New Mexico, analysis of data in the literature on food habits of heteromyids, and a re-analysis of Brown and Lieberman (1973) and Brown (1975). All of these sources agree that no seed size selection exists.

Although no pattern of simple seed size selection was found, interesting differences were noticed among species. First, the tendency to husk appears to be related to the size of the rodent. Second, large …

The Mining Of Coal In Bristol, Rhode Island: Potential Methodology, Impacts, And Evaluation Of Community Response, Norman Kahn

Marine Affairs Theses and Major Papers

This report addresses the potential commercial mining of coal in the coastal community of Bristol, Rhode Island, with respect to methodology and community response.The attitude of the local community towards any mining proposal will greatly influence the course of development of the resource. In addition, maximum community participation is mandated by both Federal and State law (NEPA and the Rhode Island Coastal Zone Management Act, respectively) (7, 8). It is to be expected that the character of the response will be mediated to a great degree by the expected impacts of the mining operation. For this reason, the methods of …
