Phylogeography And Population Structure Of The Prairie Skink (Eumeces Septentrionalis), Gregory S. Fuerst

Theses and Dissertations

The geographical and geneological limits of species are firmly rooted in historical and current processes. Phylogenetic studies focus on the historical aspect and examine character states to estimate ancestor-descendent relationships. The number of described species in the world has been estimated at 1.4 to 1.8 million and other estimates suggest that as many as 30 million species may exist (May, 1990; Wilson, 1992). Phylogenetic studies provide the information needed to delimit and classify these species based on their historical relationships. Studies on species population structure focus on the current and historical processes acting on a species. These studies use a …

Genetic Structure And Isolation By Distance In Napaea Dioica L. (Malvaceae): An Analysis Of Microsatellite Dna Variation., Jonathan Paul Wenger

Theses and Dissertations

Napaea dioica L. (Malvaceae) is a robust, dioecious perennial flowering plant that is endemic to the upper midwestem United States. Occurring exclusively on the floodplains o f small rivers, populations o f N. dioica are distributed discretely on a network o f riparian habitat throughout its range which is coincident with the southernmost margin o f the Wisconsinan continental glacier. Ten population o f N. dioica were sampled across the species geographic range and were assayed at four high resolution microsatellite marker loci to assess genetic diversity and population structure in relation to the riparian habitat network and the ecological …

The Paleoecologic Significance Of Paleocene Palynomorph Assemblages From The Ludow, Slope, And Cannonball Formations, Southwestern North Dakota, Timothy J. Kroeger

Theses and Dissertations

Paleoenvironment exerted control on the distribution of 133 palynomorph taxa from the Ludlow and Slope Formations and Boyce and Three V Tongues of the Cannonball Formation (Fort Union Group, I Paleocene) of southwestern North Dakota. The strata represent fluvial deltaic systems that prograded eastward into the Cannonball Sea. Depositional environments include distributary channels, crevasse splays, crevasse-splay feeder channels, lignite-producing swamps and/or marshes, lakes, brackish to slightly brackish bays, lake and bay fills, and marshes

Paleoenvironmentally sensitive palynomorph taxa were identified by subjective examination of pollen diagrams and objective analysis using detrended correspondence analysis. Two paleoenvironmentally restricted palynomorph associations were recognized. …

The Impact Of Cowbird Parasitism On A North Dakota Population Of Clay-Colored Sparrows, Gregory P. Romig

Theses and Dissertations

The study was conducted from early May to late July, 1992 at Oakville Prairie, Grand Forks Co., North Dakota. The clay-colored sparrow (Spizella pallida) was the most common breeding bird at the site. Also abundant at Oakville was the brown-headed cowbird (Molothrus ater) , an obligcite brood parasite. The main objectives of the study were to assess the impact of cowbird parasitism on the reproductive success of this clay-colored sparrow population, and to examine some factors that may influence the probability that a given nest will be parasitized.

Forty-two clay-colored sparrow nests were found, and of these, 16 (38%) were …

Distribution And Occurrence Of Eriogonum Visheri A. Nels. On The Medora And Mckenzie Districts, Little Missouri National Grasslands, In North Dakota, Staria S. Vanderpool

Theses and Dissertations

Eriogonum visheri A. Nels. (Polygonaceae) is a plant species whose distribution in North Dakota is incompletely known. The plant species is listed by North Dakota Heritage Program personnel as a G5/S2S3 [G5 = demonstrably secure globally, although it may be rare; S2 = imperiled in the state (6-20 occurrences) or vulnerable to extirpation; S3 = rare in the state (20+ occurrences)]. The species is Federally listed as C2 [current information indicates that listing as endangered or threatened may be warranted, but information about the species is presently inadequate to support immediate ruling] (Northern region, USDA Forest Service, 1991). The limited …

The Ecology Of Neotropical Forest Tree Seedlings., Mingguang Li

Theses and Dissertations

Patterns of seedling demography were studied in undisturbed wet forest at La Selva Biological Station, Costa Rica. In 1983, permanent transects were established at random locations, in which all seedlings $\le$0.5 m in height belonging to all species capable of reaching 10 cm dbh were tagged, identified, mapped, and measured in height. During the following 18 months, a total of 6,403 seedlings belonging to 194 species were tagged. All tagged seedlings were recensused at regular intervals.All but 302 tagged seedlings had died by June 1989, the total mortality rate was 95.3% for a period of 6 years. The mean one-year …

The Effects Of Metals On Growth And Nitrogenase Activity Of The Soil Cyanobacterium, Nostoc Commune Vaucher., Charles Lyle Pederson

Theses and Dissertations

The overall purpose of this study was to provide basic data regarding the influence of metals on a free-living terrestrial cyanobacterium, and to demonstrate the utility of laboratory studies for assigning biological significance to field observations on soil-algal ecology.Because Nostoc commune Vaucher is a subaerial inhabitant of soils, it did not respond favorably to traditional liquid culture techniques. Therefore, a filter-culture technique was developed whereby N. commune was grown as a surface film on membrane filters superimposed on an inorganic nutrient agar. Filter-cultures were established by inoculating sterile cellulose acetate membrane filters with a layer of N. commune. Growth rates, …

Recent Changes In The Ethnobotany Of Standing Rock Indian Reservation, Shelly Katherene Kraft

Theses and Dissertations

Gathering arid preserving wild fruits and vegetables for food and medicine, especially from the wooded bottomlands, was a traditional part of the Lakota culture. Plant use among the Lakota has been greatly reduced and in some cases, completely eliminated by the damming of the Missouri River by Oahe Dam. This dam, which forced the Lakota of Standing Rock Reservation to give up their homes in the bottomlands in violation of their treaty rights of 1868 had a considerable impact on the biogeography of the Standing Rock Indian Reservation, in January I960, almost 200 Indian families were evacuated from their homes …

Summer And Fall Ecology Of Mule Deer In The North Dakota Badlands., William Fredrick Jensen

Theses and Dissertations

I studied mule deer (Odocoileus hemionus hemionus) ecology in summer and fall on the Kinley Plateau study area (KPSA) of Billings County, North Dakota, during May-December 1984-1986. The primary objective of this research was to examine habitat use by mule deer in North Dakota's badlands. Data also were collected on vegetation composition, and social structure, activity patterns, and movement of the deer.I captured and individually marked 19 fawns during the summers of 1984-86. Between 1981-85, 46 older individuals also were trapped and marked. Movements of radio-collared animals (N = 16) were monitored by use of a hand-held yagi antenna and …

Aspects Of Mammalian Predation On Upland Nesting Waterfowl In Central North Dakota, John Thompson Trevor

Theses and Dissertations

The impact of mammalian predation on upland nesting waterfowl was studied in central- North Dakota during the summers of 1987 and 1988. Survival of artificial nests was examined in relation to nest density, vegetation cover, distance from roads, active predator dens, and other artificial nests in a plot. Survival of artificial nests was also compared between an area with predator control and one without predator control.

Artificial waterfowl nests located in high density plots had a significantly lower probability of survival than nests located in low density plots. Although there were significant differences in vegetation height and density between years, …

Ecology Of Gray Partridge In North Dakota, John Patrick Carroll

Theses and Dissertations

I studied gray partridge (Perdix perdix) ecology in north-central North Dakota during 1985-87. The primary goals of this study were to identify habitats important to gray partridge survival and nesting, and to provide baseline data on partridge ecology in North Dakota. I captured and radio-tagged 100 gray partridge, mainly during winter. Individuals were tracked by a vehicle-mounted telemetry system until August of each year. Home ranges, movements, habitat use, and survival were calculated by using the telemetry locations. Winter home ranges averaged 117 ha, and were larger than previously reported in North America. Important habitats used by radio-tagged partridge during …
