Some Limnological Conditions Relative To Winter Kill Of Fish In Ice-Covered Representative Farm Ponds In Eastern South Dakota, Jerome L. Johnson Jan 1960

Some Limnological Conditions Relative To Winter Kill Of Fish In Ice-Covered Representative Farm Ponds In Eastern South Dakota, Jerome L. Johnson

Electronic Theses and Dissertations

An aquatic environment involves many complex relationships biologically, physically, and chemically. Many of these relationships are difficult to measure or are little understood. In nature, aquatic environments accommodate many types of aquatic life. Ecological disturbances may cause the environment to become unfit for economically important forms of life. Human interferences often causes polluted waters and naturally occurring disturbances are common. A disturbance of this kind is one of the major problems of fisheries management in the northern Great Plains area – seasonal anaerobosis of fish or other aquatic animals and plants, commonly known as winter kill. Winter kill is usually …

Nesting Of Mourning Doves In Eastern South Dakota, Lloyd E. Oldenburg Jan 1959

Nesting Of Mourning Doves In Eastern South Dakota, Lloyd E. Oldenburg

Electronic Theses and Dissertations

The mourning dove¹, not presently a game bird in South Dakota, is gaining support toward that status. During the 1959 state legislative season a bill sponsored by the Department of Game, Fish and Parks to place the mourning dove on the game bird list was passed by the House and defeated by the Senate. In a special dove issue of Outdoor California, January 1959, W.K. Kiel (9) stated there are currently 30 states which allow dove hunting. No state bordering South Dakota has an open dove season. However, in a special memorandum of March 7, 1958, the Nebraska Game, Forestation …


A Probability Sampling Design For The City Of Brookings, South Dakota, Marian Egeberg Flesner Jan 1959

A Probability Sampling Design For The City Of Brookings, South Dakota, Marian Egeberg Flesner

Electronic Theses and Dissertations

The purpose of this thesis is to design an efficient sample of families in Brookings which can be used in analyzing the consumption pattern of the families in this city. The particular design which will be recommended is one which may be applied to other cities such as Madison, Watertown, and Aberdeen. The design will provide for a probability sample with a predetermined probability of selection of the individual family. The reasons for the selection of a probability rather than a non-probability sample are discussed in the following paragraphs.


Wildlife Utilization Of Stock Ponds In Minnehaha County, South Dakota, James D. Swanson Jan 1959

Wildlife Utilization Of Stock Ponds In Minnehaha County, South Dakota, James D. Swanson

Electronic Theses and Dissertations

Introduction: Man’s agricultural activities in South Dakota have greatly altered environmental conditions for nearly all forms of wildlife. Draining and ditching in eastern South Dakota have decreased the acreage of wetlands available to waterfowl and furbearers. Results of conversation practices carried out under the Agricultural Conservation Program as reported by the U. S. Department of Agriculture (1) show that between 1936 and 1937 South Dakota farmers had drained 760,198 acres. Drainage of wetland areas changed once valuable wildlife habitat into drylands which are of little value to waterfowl and furbearers. Waterfowl breeding grounds have been so greatly reduced that few …


Analysis Of Summer Spotlighting For Determining Deer Populations Indices, Donald C. Duerre Jan 1959

Analysis Of Summer Spotlighting For Determining Deer Populations Indices, Donald C. Duerre

Electronic Theses and Dissertations

Man changes his environment to suit his needs. In doing so he has destroyed forests, plowed the land, and built cities. Deer have adopted themselves to these changes, and in many instances populations have erupted as a result. Their ability to survive advancement of civilization and increasing hunting pressure has made deer the most important big-game animal in America, The importance of deer as a game animal has caused game agencies to institute more intensive management programs. Proper management of this species has long been a problem of game technicians. In order to obtain an optimum annual harvest, the technician …

Estimating Commercial Expansion In Brookings Resulting From The Anticipated Increases In South Dakota State College Enrollments, Norma Ruth Koch Jan 1958

Estimating Commercial Expansion In Brookings Resulting From The Anticipated Increases In South Dakota State College Enrollments, Norma Ruth Koch

Electronic Theses and Dissertations

An educational institution such as South Dakota State College benefits the community in which it is located in various ways. In addition to the benefits which accrue from the services which the college provides to the community, and from research, educational, cultural and recreational facilities which are open to members of the community, material benefits, such as additional employment, consumer population and business activity are also derived from a college’s enrollment and employment. In order to determine the material benefits which Brookings will derive from the location of South Dakota State College in the community, an estimate of the business …


Construction And Evaluation Of The Performance Of A Horizontal Well In A Shallow, Thin Aquifer, Eugene J. Doering Jan 1958

Construction And Evaluation Of The Performance Of A Horizontal Well In A Shallow, Thin Aquifer, Eugene J. Doering

Electronic Theses and Dissertations

Since infiltration galleries have been effective as a means of securing large quantities of water from thin aquifers, the question has arisen as to whether or not a small horizontal well that would yield sufficient water for irrigation could be constructed at a cost that would be within the budget of the family-sized farm in South Dakota. If so, a subsequent problem would be the development of some method of estimating the quantity of water a particular aquifer will yield to such a well. A possible approach would be to relate a certain length of horizontal casing to a vertical …


Age And Growth Determination Of The Black Bullhead From Soft Fin Rays, James W. Sprague Jan 1958

Age And Growth Determination Of The Black Bullhead From Soft Fin Rays, James W. Sprague

Electronic Theses and Dissertations

Introduction: Knowledge of the age of individuals comprising populations of fish is essential to the fishery biologist. From such information he is able to calculate the rate of growth, determine the age at which sexual maturity is attained and the longevity of the species. These calculations and determinations can be applied in the management of populations and in setting fishery regulations. There are numerous methods being used to determine the age of an individual fish. Of these, the scale method is the most important means of age determination being utilized with species of fish possessing scales (Cooper, 1951). This method …
