Habitat Preferences And Food Habits Of Striped Skunks In Eastern South Dakota, Melvin S. Moe
Habitat Preferences And Food Habits Of Striped Skunks In Eastern South Dakota, Melvin S. Moe
Electronic Theses and Dissertations
Habitat preferences of striped skunks (Mephitis mephitis) in Brookings County, South Dakota, were determined rom the relationship of nighttime roadside indices to 25 habitat variables of 277, 1-square mile plots. Winter tracking was also conducted. Skunks were collected on the study area in 1972-1972, and contents of 59 stomachs and 63 colons were studied to determine food habits. Indices of prey abundance in different habitat types were obtained from snap-trap surveys. The 25 variables accounted for 14.9 percent of the variation in skunk numbers. The relationships of three of these variables to skunk numbers were significant (P<0.05). The significant variables and the variation accounted for by each were: (a) number of areas of idle grassland, 6.3 percent; (b) number of rockplies, 1.5 percent; and (c) acreage of idle grassland, 1.3 percent. Idle grasslands were the main activity centers of skunks tracked during the winter. Food habits were analyzed for the periods March-April, May-June, July-August, and September-November. Insects were the most frequently found food item in al time periods except March-April, during which mammals occurred more frequently. Mammals made up the largest volume of food in March-April and May-June. Amphibians made up the greatest volume in July-August, while amphibians, mammals, and insects were found in nearly equal volumes in September-November. Bird remains occurred during all time periods. Eggs were found in May-June and July-August. Meadow voles (Microtus spp.), the most frequent mammalian food item during all time periods, were common only in habitat types having heavy residual cover. Idle grassland is an important nestling cover for gamebirds and waterfowl. Since the number of areas of this cover type apparently has a stronger relationship with skunk numbers than its total acreage, grassland nesting cover might best be managed in large, homogeneous blocks. Areas managed in this way would probably support lower skunk densities than more diverse areas containing equal acreages of idle grassland, thus reducing nest predation by skunks. Skunk control programs should be most efficient when centered around idle grassland and rockplies.

Influence Of Vegetation On The Distribution Of Small Mammals On A Waterfowl Production Area, Douglas A. Searls
Electronic Theses and Dissertations
. A study was conducted on a Waterfowl Production Area in Brookings County, South Dakota in 1972-73 to determine the distribution and abundance of small mammals. Three cover types, reseeded native grassed, brome-alfalfa, and bluegrass, were studied. Meadow voles (Microtus pennsylvanious), and deer mice (Peronyscus maniculatus) were captured most frequently. Jumping ice (Zapus hudsonius), masked shrews (Sorex cinerius), short tailed shrews (Blarins brevicauda), grasshopper mice (Omychomys leucogaster) and house mice (Mis musculus) were also taken. The bluegrass association had the highest number of small mammal captures and the reseeded native grass association has the least. There was no significant difference …

Consumer Installment Loan Risk: A Discriminant Analysis, Ronald Edward Fisher
Electronic Theses and Dissertations
All lending institutions are faced with the fact that a portion of their outstanding loans will not be repaid. A loan officer, or other designated individual, is normally charged 'it h the responsibility of evaluating loan applicants in terms of their comparative risks in order to reduce this inherent cost of doing business. The loan officer has traditionally evaluated consumer installment loan applicants using the three C's rule: character, collateral and capacity to repay, as his guideline for evaluating risk. The information required for this type of evaluation came from the data on the loan application, a credit check and …
Molecular Orbital Calculations For [Mo(Cn)₈]⁴⁻ An Investigation Of Eight Coordination Geometries, Patty S. Herman
Molecular Orbital Calculations For [Mo(Cn)₈]⁴⁻ An Investigation Of Eight Coordination Geometries, Patty S. Herman
Electronic Theses and Dissertations
Until the last twenty years only a few discrete 8-coordinate transition metal complexes were known. Increased interest in 8-coordination has led to the synthesis and characterization of a great many 8-coordinate compounds. Application of 3-dimensional X-ray analysis has made structural determination of these complexes much simpler. Two configurations dominate the stereochemistry of discrete 8-coordination, the D4d square antiprism and the D2d triangular dodecahedron. Both of these structures can be obtained by distorting the cube, a configuration not commonly observed. A 45° rotation of one square face of a cube about the perpendicular axis through that face results in the antiprism …
Development Of A Control System For Positioning The Centerbody In A Choked Inlet, John Jacob Jibben
Development Of A Control System For Positioning The Centerbody In A Choked Inlet, John Jacob Jibben
Electronic Theses and Dissertations
Since the introduction of high bypass ratio turbofan engines, the noise problem from aircraft shifted primarily from jet noise to noise of turbomachine origin. The present dominant noise source is the inlet noise generated by the first compressor stage (or the fan). Acoustic liners to reduce this noise have met with only limited success since the noise reduction to cost ratio is quite low. There are also many technical problems with acoustic liners that are not completely solved. Another method is by means of the choked inlet. This device simply accelerates the air to sonic velocities in the opposite direction …
Themes Expressed In The Rhetoric Of Two Women's Rights Movements, Ann Holt Logan
Themes Expressed In The Rhetoric Of Two Women's Rights Movements, Ann Holt Logan
Electronic Theses and Dissertations
Throughout American history, the question of women's rights initiated a substantial body of rhetoric. The two most prominent women's rights movements seem to be the woman's suffrage movement from 1848 to 1920 and the current women's liberation movement. The recurrence of organized movements on the subject of women's equal rights raises the question whether the themes expressed in the rhetoric of each movement are similar. Therefore, the purpose in this investigation was to discover the extent to which speaking on behalf of women's rights by women utilized recurring themes. The two most prominent women's rights movements seem to be the …

Electronic Theses and Dissertations
A photolysis system was designed for meticulous exclusion of oxygen and moisture. Photolyzed ethanol solutions of dioxobis(acetylacetonato)-molybdenum(VI), Mo02 (acac)2, were studied via preparation of derivatives with several uninegative bidentate ligands (chelH, cysteine was designated cystH2) and pyridine (py). Infrared spectroscopy was a useful tool in identifying these compounds. An oxomolybdenum(IV) compound, MoO(dtc)2 was isolated from the red photolyzed solution when dtc was the N,N-diethyldithiocarbamate ion. Tropolone, 8-hydroxyquinoline, N,N-diethyldithiocarbamate, and cysteine formed products formulated as the dioxo bridged molybdenum(V) compounds, Mo204(che1)2. Acetylacetone, tropolone, 8-Hydroxyquinoline and N,N-diethyldithiocarbamate, formed derivatives formulated …
A Neoclassical Growth Model With An Environment Sector, Gregory Henry Wagner
A Neoclassical Growth Model With An Environment Sector, Gregory Henry Wagner
Electronic Theses and Dissertations
Current discussions often link economic growth as a causative factor in the increase of pollution. Growth in the economy has a number of causes. These include technological innovation, resource discovery and population growth along with the most widely discussed, investment. Economic growth in its advanced stages can cause severe depletion of raw materials, environmental pollution from energy use, and overtaxing of the environment's capacity to absorb and recycle waste products. A simple solution to growth related pollution would be to reduce the rate of growth and therefore reduce pollution. Herein lies a dilemma. Edwin L. Dole has written that reducing …
The Existence Of Reversed Digit Addends Modulo N, Lance Adair Wheeler
The Existence Of Reversed Digit Addends Modulo N, Lance Adair Wheeler
Electronic Theses and Dissertations
One of the most interesting and commonly pursued branches of mathematics is the study of number theory. Its appeal lies not in its applicability, but in a fascination for the properties of the numbers themselves. It should be noted that, on occasion, problems of number theory have contributed to more pragmatic branches of mathematics and hence to a practical application. Frequently this happens without the original author's expectation or intention since he was merely remarking on what he considered to be a singular or unusual facet of the employed number system. Such a problem is that which involves the rearrangement …

The Economic Feasibility Of Confinement Feedlots And The Analysis Of Seasonal Marketing Variations For Feeder Cattle In South Dakota, Daniel W. Francke
The Economic Feasibility Of Confinement Feedlots And The Analysis Of Seasonal Marketing Variations For Feeder Cattle In South Dakota, Daniel W. Francke
Electronic Theses and Dissertations
South Dakota apparently produces an adequate quantity of feeders and feed grains to substantially increase slaughter cattle production. Furthermore, South Dakota prices for feed grain, roughage, and feeder cattle are equal to, or less than, the prices for these inputs in other areas where cattle feeding has flourished in recent years. It should also be determined how South Dakota farmers might increase fat cattle production. Therefore, in an attempt to explain South Dakota's slow cattle feeding growth and possibly help farmers in South Dakota and neighboring areas develop the cattle feeding industry, the following problems were researched. First, this area …
