Nesting Of Mourning Doves In Eastern South Dakota, Lloyd E. Oldenburg
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 …
Age And Growth Determination Of The Black Bullhead From Soft Fin Rays, James W. Sprague
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 …

Common through the Great Lakes and many of the inland lakes and …

Digestion Studies With Sheep And Wild Antelope On A Sagebrush Ration, Paul Harold Kohler
Digestion Studies With Sheep And Wild Antelope On A Sagebrush Ration, Paul Harold Kohler
Electronic Theses and Dissertations
Introduction: Those who are responsible for the management of antelope, range livestock, and the range seek to maintain such a balance that al may thrive and reproduce. This is inevitably a difficult objective since the balance in numbers of antelope and livestock may be changed annually, but range flora changes only in long-time cycles. Therefore, the balance between the wild and domestic species and the range must be adjusted frequently by range and livestock management. The adjustment of the number of domestic animals to fit the carrying capacity of the range may be accomplished by changing management and marketing practices …
Progress Report On The Ground-Water Resources Of The Las Vegas Artesian Basin, Nevada, George B. Maxey, C. Harry Jameson
Progress Report On The Ground-Water Resources Of The Las Vegas Artesian Basin, Nevada, George B. Maxey, C. Harry Jameson
Publications (WR)
Whether the tremendously increased population acquired by Las Vegas in the years 1940 to 1942 will be retained cannot at present be foretold. However, the valley will undoubtedly be expected to support a considerably larger population than it did at any time prior to 1940, and continually increasing demands on the water supply for innumerable pcacetimc activities must be anticipated. Therefore, a sound evaluation of tho ground water resources of Las Vegas Valley is directly in line with the other wisely progressive planning programs which are now operating or are taking shape in the valley as well as in the …

Bird Studies Of The Bear River Marshes, Ernest W. Parkinson
Bird Studies Of The Bear River Marshes, Ernest W. Parkinson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The establishment of the Bear River Bay Bird Refuge has created for the state of Utah an immense and valuable biological field, a veritable paradise for naturalist and sportsman alike. The naturalist wants a place to study wild life and the sportsman desires game. With the proper control of open seasons on wild fowl the hunting instinct and incentive for the sport should be satisfied for the sportsman. To the naturalist this region will open up bountiful treasures of knowledge that is to be gained only by intense and prolonged scientific study.
