Water Quality Changes Under Ice Cover In Northern Prairie Lakes, Steven P. Gloss
Water Quality Changes Under Ice Cover In Northern Prairie Lakes, Steven P. Gloss
Electronic Theses and Dissertations
Water quality changes under ice cover were studied in seven northern prairie lakes. The lakes are high in dissolved materials and exist essentially as closed systems during the winter months. Ice cover ranging from 53 to 86 cm developed on the lakes. Melted ice samples showed small amounts of dissolved impurities present in surface layers of the ice. No substantial concentrations of any ions were found in the ice of lower layers. Specific conductance increased over 40% under ice cover in two of the lakes studied. Increases in other lakes ranged from 19 to 38%. Major ions showed increases similar …
Evaluation Of The Ovulated Follicle Technique As A Means Of Determining Pheasant Production, C. Denis Allen
Evaluation Of The Ovulated Follicle Technique As A Means Of Determining Pheasant Production, C. Denis Allen
Electronic Theses and Dissertations
A study of the ovulated follicle technique for determining egg production in pheasants was conducted during 1967 - 1969. Evidence indicated collection of wild hens for follicle counts should be between 5 and 14 weeks after cessation of laying. Questionable follicles encountered should be considered ovulated follicles and included in the counts. Most questionable follicles were believed to originate from ovulated atretic follicles that were harder to identify because of their particular stage of regression. The influence of freezing on atretic follicle counts was studied, and no adverse effects were found. A technique was developed for selectively staining atretic follicles. …
Summer Movements Of Bigmouth Buffalo In Lake Poinsett, South Dakota, Thomas J. Clifford
Summer Movements Of Bigmouth Buffalo In Lake Poinsett, South Dakota, Thomas J. Clifford
Electronic Theses and Dissertations
Movements of bigmouth buffalo in Lake Poinsett, South Dakota were studied from 1 June to 31 August, 1968. Bigmouth buffalo were individually marked with Styrofoam floats and tracked visually during daylight hours. Buffalo at a relatively constant, slow rate averaging .346 km/hr (0.05 km/hr to 1.4 km/hr). Two study indicated that bigmouth buffalo in Lake Poinsett had no home range or homing tendency and inhabited all vertical strata. Bigmouth buffalo schools in Lake Poinsett exhibited a free interchange of individuals. An evaluation of large mesh gill nets as a commercial fishery tool indicated that 10.0 cm bar measure gill nets …
Fish Populations Of Two Small Impoundments In Northeastern South Dakota, William C. Thorn
Fish Populations Of Two Small Impoundments In Northeastern South Dakota, William C. Thorn
Electronic Theses and Dissertations
Thirteen species and large standing crops of fish were found in Blue Cloud Abbey Pond and Labolt Pond, South Dakota. Adult population was estimated to be 5184 fish in Abbey Pond and 5016 in Labolt Pond. Composition of the populations differed. Black crappies were most numerous in Abbey Pond; white crappies, in Labolt Pond. Total standing crop of adult fish in Abbey Pond (573.1 kg/ha) was slightly greater than in Labolt Pond (550.6 kg/ha). Black crappies in Abbey Pond and white suckers in Labolt Pond were the species with highest standing crops. Growth of fish was more rapid in Labolt …
Effects Of Aldrin On Young Pheasants Under Semi-Natural Conditions, Ronald Eugene Thill
Effects Of Aldrin On Young Pheasants Under Semi-Natural Conditions, Ronald Eugene Thill
Electronic Theses and Dissertations
Effects of aldrin on young pheasants were studied under semi-natural conditions in four one-acre enclosures during the summer of 1968. The center two-thirds of each plot was planted in corn; remaining peripheral cover was maintained in smooth brome and alfalfa. Prior to planting, center portions of two plots were sprayed with 2 pounds of aldrin per acre on Hay 20, while remaining plots served as controls. On June 12, four family units consisting of two broody pheasant hens and two bantam hens with 15 three-day-old chicks each were confined in plots. Hens and broods were given free run 10 days …
An Evaluation Of The Roadside Technique For Censusing Breeding Waterfowl, Darrel W. Sauder
An Evaluation Of The Roadside Technique For Censusing Breeding Waterfowl, Darrel W. Sauder
Electronic Theses and Dissertations
An evaluation of the roadside technique for censusing breeding waterfowl was conducted in east-central South Dakota. On the 54-mile transect used in 1968, number of coutns necessary to be within 20 percent of population mean with specified confidence of 0.90 for blue-winged teal (Anas discors) and gadwall (Anas strepera) was five and three using miles or wetlands. Within same limits counts needed for mallard (Anas platyrhynchos) were at least four for miles and three for wetlands. Shorter transects, used in 1967 required more counts. Transects 21 miles long required up to 10 counts based on miles and 11 based on …

The Effect Of Replication On Queueing Simulations, Musvathy K. Dyanesh
The Effect Of Replication On Queueing Simulations, Musvathy K. Dyanesh
Electronic Theses and Dissertations
Many industrial systems may be characterized as an arrival of some type of unit (such as sales orders, batches of raw material to be transformed into parts or broken machines) to a system of servicing stations. In the service stations, the units are serviced in some manner. Thus, the sales order requires checking and preparation of additional paper work; the materials to be transformed require the machines upon which the production process takes place, and the broken machine requires the repair personnel. Waiting lines or queues may form due to lack of control over either the rate of arrival of …

Aeration Of Stockade Lake, South Dakota, Larry C. Vanray
Aeration Of Stockade Lake, South Dakota, Larry C. Vanray
Electronic Theses and Dissertations
Intermittent aeration of Stockade Lake (2,470 acre feet) during the summers of 1967 and 1968 temporarily altered the thermal profile and phytoplankton density. Continual aeration for 48 hours in the deepest portion of this eutrophic lake produced epilmnetic cooling, hypolimnetic warming and apparent reduction of algal populations at three sampling stations in various parts of the lake. Dye, released at the aeration site, was found at all depths throughout the lake after 461/2 hours aeration. Air bubbles, rising from diffuser blocks near the lake bottom, carried cold, hypolimnetic water to the surface at a rate of 4.7 million gallons per …
