Effects Of Atrazine On Penned Pheasants And The Occurrence Of Stress Marks On Feathers, Thomas Orin Melius

Electronic Theses and Dissertations

Doses of 4 g of atrazine (AAtrex) were not lethal to penned hen pheasants (Phasispus colchicus), but levels of 6, 8, 10 and 12 g induced mortality. Pen studies to determine the effects of atrazine on reproduction of hen pheasants were conducted with two replicates of the basic test. Birds were administered treatment levels of 0, 100, 200, or 400 mg of atrazine per hen per week. Egg production and gain in weight of hens were unaffected by the treatments. Replicate A eggs were unaffected by the treatments. Replicate A eggs were unaffected in shell thickness and pipping rates, while …

Nesting Ecology Of The Ring-Necked Pheasant In Eastern South Dakota, Richard A. Olson

Electronic Theses and Dissertations

Nesting of the ring-necked pheasant (Phasianus colchicus) was studied in 1973 and 1974 and 90 randomly chosen 4.05 – ha plots in the Lake Sinai Township of south-western Brookings County. Nest initiation and hatching peaks over the 2-year period occurred from 1-15 may and 16-30 June, respectively. Average density of nests was 0.3 per hectare in 1973 and 0.2 in 1974. Average clutch size for combined years was 8.6 for all nests and 10.8 for nests where clutches hatched. Clutch sizes declines as the nesting season progressed. Fertility of eggs in nests where clutches hatched was 96 percent. Hatching success …

Food Habits Of Young-Of-The-Year Fishes In Abbey Pond, South Dakota, Randall D. Radant

Electronic Theses and Dissertations

Food habits of young-of-the-year largemouth bass (Micropterus salmoides), bluegill (Lepomis macrochirus), black crappie (Pomoxis nigromaculatus), yellow bullhead (Ictalurus natalis), and yellow perch (Perca flavescens) were studied during 1973 and 1974 in Abbey Pond, South Dakota. Organisms found in young-of-the-year fish stomachs and in plankton samples were identified and counted in the laboratory. Zooplankton, aquatic insects and fish were the most important food organisms consumed by young fishes. Using Ivlev’s electivity index food electivity by the fishes for zooplankton was calculated. The size-specific food habits of young-of-the-year largemouth bass progressed from entomostracans to aquatic insects to fish. In most cases zooplanktons …

Distribution And Importance Of Stockdams, Dugouts, And Natural Wetlands To Breeding Waterfowl In South Dakota, James J. Ruwaldt

Electronic Theses and Dissertations

Wetland distribution and utilization by breeding waterfowl of stockdams, dugouts, and natural wetlands were investigated in South Dakota during 1973 and 1974. Wetlands in South Dakota were estimated to encompass 590,499 ha and to total 631,557 basins. Natural ponds and lakes comprised 74.7 percent of the wetland area and 46.0 percent of the total number. Stockdams composed 13.9 percent of the wetland area and 14.0 percent of the number, and dugouts 0.3 percent and 8.1 percent of the state’s wetland area and number respectively. Ninety-one percent of the ponds and lakes were found east of the Missouri River and 86.7 …

Results And Evaluation Of An Aerial Creel Survey Technique On Lake Sharpe, South Dakota, Bruce R. Schmidt

Electronic Theses and Dissertations

A creel survey, consisting of two independent surveys, was conducted on Lake Sharpe, South Dakota from May, 1973, through May, 1974. An aerial fisherman count was used to estimate fishing pressure and an angler interview survey was used to estimate catch rates, mean party size, mean fisherman day, and residence of the anglers. The results of the two surveys were combined to estimate harvest. The separate surveys were combined to estimate harvest. The separate surveys allowed optimum stratification and allocation of sampling effort for each. Estimated fishing pressure was 32,643 fisherman-hours, ±9.60% at the 95% confidence level, and the total …

Human Problem Solving Of Two Applied Tasks In Economic Allocation, Jerry Alan Kackley

Electronic Theses and Dissertations

The objective of this paper is to examine in depth one aspect of human problem solving; specifically, to deal with a task environment familiar to the managerial practiocioner --- one of allocating scarece resources in an equitable and efficient manner toward the accomplishment of a defined goal. The central focus will be on measuring the problem solver’s relative efficiency and equitability in solving this allocation task using two different sets of data. To observe the problem solver’s thought processes, the “thinking aloud protocol” will be used. The use of protocols in discussed in Chapter 2. Of prime importance in the …

A Non-Silver Based Photographic Process And The Crystal And Molecular Structure Of 3,7-Dihydroxyl-1,5-Bis (P-Bromophenyl) Octahydro-1,5 Diazocine, Cary Y. Peters

Electronic Theses and Dissertations

A film process based on the reduction of nickel (II) to elemental nickel, which is sensitive to x-ray energy photons as well as electrons, has been reported.¹ Research using this process was carried out using copper Kphotons generated from an x-ray source and an electron beam from an electron microscope. Possible advantages of this type of film process are low cost, elimination of darkroom procedures, and the stability of the exposed and unexposed film for long periods of time.

Encephalitis Epidemiology In South Dakota : The Development And Use Of An Encephalitis Simulation Model And A Computerized Human Serum Bank To Determine Western And St. Louis Encephalitis Activity, Curtis Dean Wilson

Electronic Theses and Dissertations

The investigation reported here represents an attempt to relate a virus vector simulation model with field observations made in South Dakota over the past years. The viruses that will be examined are two encephalitis viruses, western equine encephalitis (WEE) and St. Louis encephalitis (SLE). Since the encephalitis viruses are grouped within the arboviruses, viruses transmitted by an arthropod vector, any epidemiological study of the human and horse encephalitis outbreak process must include a study of the vector, in this case mosquitoes, and the factors affecting that vector. It is this complex relationship of virus, vector and hosts that led those …

Tetrazoline Chemistry, Norman Wallace Rokke

Electronic Theses and Dissertations

It was of interest to investigate the chemistry of some tetrazolines since they might be sources of heteroatomic analogues of trimethylenemethane. In addition, they might provide alternate means of synthesis of small ring compounds such as diaziridinones and diaziridineimines. New compounds which were prepared are 1-(2,6-dimethylphenyl)­ tetrazoline-5-one, 1-(2,6-dimethylphenyl)-4-methyltetrazoline-5-one, l-phenyl-4-methyl-5-iminotetrazoline, l-phenyl-4-methyl-5- methyliminotetrazoline, and l-phenyl-4-methyl-5-methyliminotetrazoline methiodide. The mass spectra of the tetrazolines investigated are characterized by ring fragmentations which are helpful in determining their structure. In addition, fragmentation represents one of the few examples of a retro-1,3-dipolar cycloaddition reaction initiated by electron impact. The monosubstituted tetrazolines are thermally unstable. The course of …

Integrated Numerical Simulation Of Drip Irrigation With Subsurface Drainage, James Ray Hoover

Electronic Theses and Dissertations

A numerical method and model were developed to simulate soil moisture during steady-state and transient flow toward a tile drain. Intermittent application of water by drip irrigation and rainfall were simulated by use of finite difference approximation equations. No known analytical solution for these flow situations exists because of the complex mathematics describing unsaturated flow in the soil. The computer model is based on the electrical resistance network analog. The explicit finite difference equations were solved by the successive over-relaxation method for steady-state flow and by iteration for transient soil moisture flow. The computer program for the model consists of …

A Study Of Factors Associated With Outdoor Recreational Participation In South Dakota, James W. Delong

Electronic Theses and Dissertations

Participation by South Dakotans in selected areas of outdoor recreation was studied to determine varying extents of participation and associated selected sociodemographic, socialization and attitudinal factors. A statewide random sample of 474 heads-of-households (or their spouses) was selected and interviewed using a pretested schedule. The findings were present in three forms: a descriptive summary, a nonparametric analysis of association and a multivariate analysis. The descriptive analysis revealed fishing, hunting and lakeside camping or picnicking to be the activities participated in most frequently. Conversely, water-skiing, ice fishing and snowmobiling were participated in least. Analysis of association showed that each of the …
