Movements And Habitat Use By Hen Pheasants During Brood Rearing, Lynn E. Hanson

Electronic Theses and Dissertations

Land-use patterns characteristic of prime pheasant range in the Great Plains and prairie region have 50-75 percent of the land under cultivation according to Kimball et. al. (1956). Farmland is pheasant habitat, and the production of pheasants is therefore greatly influenced by farming practices. Considerable research has been done on rates of pheasant production, nest success, and cover preferences for nesting. However, little information has been obtained on movements and cover preferences for brood rearing. Most studies of the type of cover utilized by pheasant broods have been based on roadside and random field observations. Kozicky and Hendrickson (1951) carried …

Interpretive Potential Of South Dakota Wetlands, Douglas C. Harr

Electronic Theses and Dissertations

A study was initiated to devise a method for selecting prairie wetlands on which nature interpretation areas could be established. An evaluation form was designed to systematically identify areas of good potential and 64 prairie wetlands were evaluated. Twenty-two percent of the evaluated marshes were found to rank “excellent”: the method of evaluation was determined successful. A survey was initiated to determine visitor preferences for interpretive methods and facilities at an existing wildlife-interpretive trail. Seventy-nine percent of the visitors indicated preference for a self-guiding interpretive trail. Maps and pictures used in conjunction with self-guiding signs were deemed important. Ninety-one percent …

The Relationship Of Forward Pass Catching Ability In Football And Selected Anatomical Measurements And Motor Responses, Marlin Peter Vis

Electronic Theses and Dissertations

American football has undergone many significant changes since its first recorded game between Rutgers and Princeton in 1869. Once change has been the growth in the importance of the forward pass to the offense. Rockne cites the year 1912 as a turning point of the growth in popularity of football. It was during this year that the Rules Committee removed many of the restrictions against the forward pass and made more definite the penalties against interfering with the receiver. Rockne states that this increase in the popularity of football is due “entirely to the open game, to the increase of …

The Influence Of Various Stress Conditions On Cholinesterase Levels Of Cattle Treated With An Organophosphorus Insecticide, Mitchell J. Wrich

Electronic Theses and Dissertations

Six-to 8-months-old Hereford heifers categorized as grubby or grub-free calves were used for this research. Forty calves were purchased in 1968 and also in 1969. The grubby calves were obtained from Highmore, South Dakota, an area where calves have a history of heavy grub infestations of both Hypoderma bovis (L.) and Hypoderma lineatum (de Villers). The grub-free calves were purchased in Fargo, North Dakota. Calves raised in this area seldom are infested with cattle grubs. Specified groups of calves were subjected to 30 minutes of continuous exercise or the withholding of feed and water for 24 hours prior to treatment …

An Evaluation Of An Aerated Lagoon System Treating Combined Dairy And Domestic Wastes During Summer Operation, Douglas M. Skie

Electronic Theses and Dissertations

The Water Quality Act of 1965 and the adoption of the subsequent state water quality standards emphasized the general public's concern for the control of water pollution; for it has become the goal of our nation to maintain all American waters in a suitable condition for domestic and industrial supply, for recreation and for other beneficial uses. It is for these reasons that many communities have been faced with the problem of constructing new sewage treatment facilities or expanding present operations. The use of stabilization ponds as a means of providing sewage treatment has been the practice of many small …

Plant Analysis Of Spring Small Grains At Different Stages Of Growth, James Henry Pfeifer

Electronic Theses and Dissertations

Plant analysis has developed into a diagnostic tool for measuring the nutrient status of crops. Plant analysis promises to greatly supplement the methods now available for estimating nutrient sufficiency, and as a result, increase the yield of crops. For small grains, the sampling time recommended for plant analysis is the reproductive stage ·of growth. This period has been used to determine nutrient concentrations of N, P, K, Ca, Mg, S, Zn, Mn, and Fe. Much concern exists with regards to the accuracy of plant analysis in predicting the nutrient status of small grain plants. Concern spring wheat, and barley under …

The Relationship Of Porcine Muscle Fiber Size And Number To Management, Meatiness And Quality, Ronald J. Smith

Electronic Theses and Dissertations

For many years animal scientists have been striving to find the “foolproof” method foreseeing the desired carcass and consumer characteristics in live animals before they are slaughtered. As a result, several different live animal and carcass evaluation techniques have been developed and tested with slow but encouraging success in some areas. This “never-ending” search has been stimulated by the development of new and more sophisticated research tools and facilities as time advances. Increasing consumer demands for a muscular, trim, high quality meat product makes identification of these desired traits in the live animal and carcass necessary. Thus, the producer, feeder …

The Chemistry Of Some Unusual Carbodiimides, Donald Melvin Plautz

Electronic Theses and Dissertations

Several N¹-alkyl-N²-(N,N-dialkylamino)carbodiimides, which were found to form dimeric species, were prepared, and the structure of the dimeric species determined. A study of the reaction chemistry of both the monomeric and dimeric carbodiimides led to the conclusion that dimerization occurred via a (π2s + π2a) ground-state, symmetry-allowed mechanism, and that thermal decomposition of the dimeric species occurred via a (π2s +-π2s) excited-state, symmetry-allowed mechanism. Although dialkylphosphoramidates have been shown to be useful intermediates in the preparation of unsaturated organic nitrogen compounds, N-acyl- and N-imino-dialkylphosphorohydrazidates were found to be too unstable, forming trialkylphosphates upon distillation, to be of …

Food Habits Of Black Crappies, White Crappies, Yellow Perch And White Suckers In A Small Impoundment In Northeastern South Dakota, Dennis Unkenholz

Electronic Theses and Dissertations

Crustaceans, aquatic insects and fish were the most important food items found in stomach samples. Black crappies depended on zooplankton and aquatic insects as their major food source as they occurred in all samples and were major food items in 70 percent and 40 percent respectively. Insects, zooplankton and fish were the major food items of white crappies. Insects were the dominant forage present in 54 percent of the samples while zooplankton and fish were dominant in 36 percent and 21 percent of the samples respectively. Perch relied on crayfish, fish and aquatic insects as their major food source. Aquatic …

A Characterization Of Four Prairie Grasses, Carolyn A. Cogswell

Electronic Theses and Dissertations

Even though native range forages have been available a long time, there is little research data concerning the specific grasses characterized as native forage or browse. Little research has been done to study these forages because of their natural habitat far from research laboratories, the task of collecting enough forage for adequate sample testing, and sparse yet hardy existence and questionable known vegetative growth with each year's different climate and environmental conditions. Certainly it seems logical that at some future time the knowledge of their nutritive value will become important. Perhaps then with adequate management the rancher can improve upon …

Comparing The Effectiveness Of Two Different Methods Of Teaching A Self-Developed Consumer Education Unit In A Second Year High School Home Economics Class, Doris L. Keiner

Electronic Theses and Dissertations

Because this home economics teacher had a desire to become involved with the new trends in education, she chose to compare the effectiveness of an independent method and a traditional method of teaching a self-developed, three week consumer education unit to 31 girls in a Home Economics II class at Madison Senior High School, Madison, South Dakota. The effectiveness of each teaching method was to be measured by the change in scores of a pretest and a post test. An attempt was made to place equal numbers of high-, average-, and low-ability students in each group and to compare the …

Embryogeny In Haemmanthus Albiflos Jacquin, Ping-Fai David Lo

Electronic Theses and Dissertations

There has been concern over the controversial position of the genus Allium in the classification scheme. Allium has been put into the Liliaceae because of its superior ovary and into the Amaryllidaceae because of umbels subtended by membranaceous bracts. The first purpose of this investigation is to study the embryogenesis and subsequent embryogeny of Haemanthus to evaluate affinities between Allium and Haemanthus. Since Allium has stalked cotyledons, it was thought that we could appeal to Haemanthus embryogenesis for evidence as to its relationships, since it is a genus which has been considered both primitive with the Amaryllidaceae and related to …

Temperature Computer Measurements, Production And Carcass Traits Of Individually Fed Weight Constant Steers, Lowell M. Anderson

Electronic Theses and Dissertations

During 1968, 29 Hereford steers were individually fed and marketed at one of seven constant weight classes from approximately 386 to 522 kg at intervals of 22.7 kg. During 1970, 21 Angus and Hereford crossbred steers were individually fed and marketed at one of four constant weight classes from approximately 386 to 522 kg at intervals of approximately 45.0 kg. The amounts of edible portion, trimmed fat, removed bone and the summation of the kidney, pelvic, and cod fat were determined on the steers of both years. In 1970 two experiments examined the usefulness of an analog computer for calculation …

The Effects Of Erythropoietin, Dibenzyline, And Iron Dextran On The Hemogram Of Doe And Fetal Rabbits, Eugene Austin Gardner

Electronic Theses and Dissertations

The iron deficiency anemia found particularly in swine has a high incidence in the newborn. The nutrition of the sow inversely affects progression of the anemia. Newborn nutritional status, also, inversely augments the anemic condition. The anemia does not become apparent in the newborn until a few days following parturition. There is a drastic decrease in iron availability with succeeding decreases in normal hemoglobin formation and mature red blood cell formation. An important factor along with these conditions is susceptibility to disease leading to death. A gradual return to normal follows if the newborn survives the anemic period. This condition …

An Evaluation By Winter Wheat Of Phosphorus Carriers And The Effect Of Different Carriers On Three Phosphorus Availability Indices, Charles C. Biggar

Electronic Theses and Dissertations

Various types of phosphorus fertilizers are being commercially produced and used. Due to the different properties of these phosphate materials, their ability to supply phosphorus may differ among South Dakota soil environments. To provide data for phosphate users it is necessary to evaluate- the.se materials under varying soil and climatic conditions. Soil reaction is commonly used to differentiate conditions within the soil that are important to phosphorus utilization or fixation. Generally, where fixation is high the possibility of utilization of the added phosphorus is low. Acid soils are considered as having a high phosphorus fixing capacity. Alkaline soils are medium …

Effects Of Applied Nitrogen And Phosphorus On Native Grasslands In The Northern Great Plains, Gregory Kirk Grenz

Electronic Theses and Dissertations

The majority of the grazing lands in the Northern Great Plains are native grasslands. In some areas profits derived from these grasslands may best be increased by complete renovation and reseeding. However, many of these grasslands can be improved by practices such as deferred grazing, interseedings, rotational grazing and fertilization. This study involves the evaluation of one of these practices, nitrogen and phosphorus fertilization. It is a study that is to provide basic information which can be used to determi.ne the economic feasibility of grassland fertilization.

The purpose of this study was (1) to determine whether significant yield increases could …

Man And Nature In Herman Melville's "The Encantadas", Jay J. Jackson

Electronic Theses and Dissertations

It is in light of the fact that no critic has yet seen fit to explore "The Encantadas" with regard to Melville's theme of the man-nature dialectic that this thesis is written. It is the purpose of this paper to show how Melville views man, nature, and their relationship to each other within the bizarre setting of the Galapagos Islands. In no other work save Moby-Dick does Melville so deeply cut to the roots of the question of man and his role in the natural scheme of the cosmos. In order to examine the man-nature tension of "The Encantadas," I …
