Food Habits And Placental Scar Counts Of Bobcats In South Dakota, David Eric Nomsen
Food Habits And Placental Scar Counts Of Bobcats In South Dakota, David Eric Nomsen
Electronic Theses and Dissertations
Bobcat (Lynx rufus) food habits and placental scar counts were investigated in western South Dakota during 1978-79 and 1979-80 trapping and hunting seasons. Food habits were recorded by frequency of occurrence and placental scar counts were used to determine litter size for South Dakota bobcats. Rabbits (Sylvilagus spp. and Lepus spp.), rats and mice (primarily Microtus spp. and Peromyscus spp.), and deer (Odocoileus spp.) were identified in 56, 32, and 7% of bobcat stomachs, respectively. Analysis showed that rabbits, rats and mice, and deer occurred in 58, 36, and 9% of bobcat intestines, respectively. Occurrences in rabbits decreased from 67% …

Initial Growth And Survival Of Bluegills And Black Bullheads Stocked With Largemouth Bass In South Dakota Ponds, James J. Shelley
Initial Growth And Survival Of Bluegills And Black Bullheads Stocked With Largemouth Bass In South Dakota Ponds, James J. Shelley
Electronic Theses and Dissertations
Initial growth and survival rates were estimated for bluegills (Leponis macrochirus) and black bullheads (Ictalurus melas) stocked simultaneously with largemouth bass (Micropterus salmoides) in ponds throughout South Dakota. Mean first year survival for bluegills and black bullheads stocked in eastern South Dakota ponds was 28.6% and 67.7%, respectively. Differences in first year bluegill growth throughout the state were not detected. Total lengths for bluegills averaged 52.4 mm after one growing season statewide and 137.1 mm after two growing seasons in southeastern South Dakota ponds. Significant (P<.05) geographical differences in first year growth of black bullheads were detected with mean lengths ranging from 67.7 mm in northwest ponds to 115.5 mm in southeast ponds. The average total length for black bullheads after two growing season in southeastern South Dakota ponds was 215.2 mm. The combined effects of pH, turbidity, and bicarbonate alkalinity accounted for 67.5% of the variation in first year bluegill growth. The pond parameters total number of growing days, fish present prior to stocking, and pond surface area when combined accounted for 73.9% of the variation in first year black bullhead growth. Differences in bluegill relative weight values were not detected throughout South Dakota; the average for the state was 105.2. Mean black bullhead condition factors (K) for fish with total lengths between 128 and 191 mm were 1.85 and 1.45 for pre- and post-spawning periods, respectively. Bullheads probably spawned between 29 May and 26 June 1980.

Variables Associated With Breeding Waterfowl On South Dakota Stock Ponds, Jay A. Roberson
Variables Associated With Breeding Waterfowl On South Dakota Stock Ponds, Jay A. Roberson
Electronic Theses and Dissertations
Use of stock watering ponds by indicated breeding pairs of waterfowl was measured in the western two-thirds of South Dakota from 1973 to 1976. Multiple regression and discriminant analyses were used to describe the habitat associated with pairs of each species. Habitat variables explained 35-47 percent of the variation in pairs having small home ranges and 26-35 percent of the variation in pairs having large home ranges. Shoreline distance account for more variation in mallard (Anas Platyrhmchos) and blue-winged teal (A. discors) pairs than any other single variable. Ponds used by these pairs and shoreline distances that averaged 590 m …
The Distribution Of Small Mammals On Samuel H. Ordway Memorial Prairie, Richard D. Puetz
The Distribution Of Small Mammals On Samuel H. Ordway Memorial Prairie, Richard D. Puetz
Electronic Theses and Dissertations
Factors affecting the distribution of small mammals have been investigated for many years. Environmental characteristics which correlated with rodent populations have been found to vary from specie to specie. If Ordway Prairie were homogeneous with regard to habitat, management would be relatively simple. The prairie, however, is heterogeneous in its habitat. Intuitively one could expect that management to increase or decrease a particular species could possibly affect the population levels of other beneficial species. The objectives of this study were to document the presence, relative abundance, and distribution of small mammals on S.H. Ordway Prairie. An additional objective was to …

A Study Of Disadvantagement And Migration For Counties In South Dakota: 1960-1970, Marco Montoya
A Study Of Disadvantagement And Migration For Counties In South Dakota: 1960-1970, Marco Montoya
Electronic Theses and Dissertations
A study of the 1970 South Dakota population was conducted to determine: (1) the extent of disadvantagement by magnitude and residence; (2) the association between the extent of disadvantagement and selected socio-economic factors; and (3) the extent to which factors explaining disadvantagement also served to predict migration based on the net migration experiences of South Dakota counties during 1960 to 1970. The county was selected as the unit of analysis. Selected data from the census were aggregated and tabulated. The magnitude of family and unrelated individual disadvantagement in South Dakota during 1970 was identified for rural farm, rural non-farm, and …

Biological Control Of Musk Thistle, Carduus Nutans, In South Dakota, Dennis Morihara
Electronic Theses and Dissertations
Two sites in southeastern South Dakota were used in this study. Both sites supported unusually dense infestations of C. nutans and were chosen on that basis. Site A was located at an unoccupied farmstead in Minnehaha County, 2 miles S.W. of Crooks. This site was composed of 3 distinct infestations of musk thistle: (1) the first stand of thistles was approximately 2 x 9 m surrounded by Siberian elm, Ulmus pumila L., Conyza canadensis (L.) Cronquist (mare's tail) and a Bromus sp., probably B. inermis Leysser. The thistles in this area stood 2+ m tall at maturity. (2) The second …

The Role Of Nematodes In A South Dakota Grassland Ecosystem, James D. Smolik
The Role Of Nematodes In A South Dakota Grassland Ecosystem, James D. Smolik
Electronic Theses and Dissertations
In an attempt to elucidate the role of nematodes in a grassland ecosystem nematode taxa, number and biomass data was gathered over a three year period at the Cottonwood International Biological Program Grassland Biome site in western South Dakota. The effects of grazing intensity, sampling date and sampling depth were studied. Nematicide treatment of range grasses in field and greenhouse studies was also used to evaluate the role of nematodes. Biomass data was used to estimate the intake of plant feeding nematodes. Results obtained demonstrate that soil inhabiting nematodes constitute a significant proportion of the consumer biomass at the Cotton[1]wood …

Bionomics Of Mallophaga Of Sharp-Tailed Grouse In South Dakota, Major L. Boddicker
Bionomics Of Mallophaga Of Sharp-Tailed Grouse In South Dakota, Major L. Boddicker
Electronic Theses and Dissertations
The ecologies of chewing lice (Insecta:Mallophaga) which parasitize sharp-tailed grouse, Pedioecetes phasianellus, were studied in southwestern South Dakota from 1964 to 1967. Five hundred twenty-eight hens, cocks and chicks were collected and examined for louse damage. Louse populations were monitored each month from December, 1964, to September, 1967. Five louse species which infested grouse in the study area were Goniodes nebraskensis Carriker, Amyrsidea megalosoma Overgaard, Lagopoecus perplexus Kellogg and Chapman, Goniocotes chrysocephalus and Lipeurus maculosis Clay. Goniodes nebraskensis fed on feather parts and skin debris and was found to have seasonally fluctuating populations. Cocks carried peak populations of 250 lice/host …
Seasonal Movements And Behavior Of Ring-Necked Pheasants In Eastern South Dakota, Arthur V. Carter
Seasonal Movements And Behavior Of Ring-Necked Pheasants In Eastern South Dakota, Arthur V. Carter
Electronic Theses and Dissertations
Information was gathered on mobility, behavior, and related activities of pheasants from July 1966 to July 1968 by banding and/or marking 160 birds with backtags and radio transmitters. Food was readily available since the winters were mild with little snow. Birds moved less than 1/4 mile from roosting areas to cornfields and weed patches to feed. Numbers of birds dispersing from the study area in spring varied each of the years, but 60 to 70 remained there during the two reproductive seasons. Adult cocks traveled less than 1/4 mile when dispersing-and adult hens moved less than 1/2 mile. Movements by …
An Ecological Study Of Coleoptera Succession In Bovine Manure With Emphasis On Natural Enemies Of The Face Fly (Musca Autumnalis De Geer) In Eastcentral South Dakota, Howard Kessler
Electronic Theses and Dissertations
The frequency and succession patterns of coleopterous species in cattle dung were determined for two localities in eastcentral South Dakota during 1969 and 1970. Thirty-nine species of beetles were screened as potential predators of the face fly, Musca autumnalis De Geer, a pest of cattle and horses; and 1 Coleoptera, 1 Hymenoptera and 1 nematode were screened as parasites of the same host. Succession studies of insects inhabiting bovine manure revealed that four families of Coleoptera were recovered from the manure and, in descending order of abundance, were Hydrophilidae, Staphylinidae, Scarabaeidae, and Histeridae. The hydrophilids were first to invade freshly …
