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 …

An Ecological Perspective On Housing, Health And Well-Being, Claude Raffestin, Roderick Lawrence
The Journal of Sociology & Social Welfare
Human ecology is a term that has been used frequently since the beginning of this century to examine some of the relationships between people and their surroundings. This article presents a different interpretation to that commonly used by academics and professionals in the medical and social sciences. The ecological perspective developed and illustrated here stems from an appraisal of many contemporary contributions, and an examination of Hippocrates's treatise "On Airs, Waters, And Places". The perspective presented herein accounts for the impacts of human products and processes on the biotic and abiotic constituents of the environment, as well as the human …

Aspects Of Mammalian Predation On Upland Nesting Waterfowl In Central North Dakota, John Thompson Trevor
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
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 …
Wolf Population Survival In An Area Of High Road Density, L. David Mech
Wolf Population Survival In An Area Of High Road Density, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Wolf mortality in a high-road-density area of Minnesota exceeds that in an adjacent wilderness, and is primarily human-caused. The wolf population there is maintained primarily by ingress from the adjacent wilderness areas. A road density of 0.58 km/km2 can be exceeded and the area still support wolves if it is adjacent to extensive roadless areas.

Breeding Bird Populations Of A Floodplain Tallgrass Prairie In Kansas, Calvin Cink, Peter Lowther
Breeding Bird Populations Of A Floodplain Tallgrass Prairie In Kansas, Calvin Cink, Peter Lowther
Proceedings of the North American Prairie Conferences
Breeding birds were censused yearly from 1974-1988 on a 10.1 ha floodplain tallgrass prairie, a portion of the Baker Wetlands Research Area on the south edge of Lawrence, Kansas. Dickcissels (Spiza americana) were the most abundant species, with densities about six times greater than in the Flint Hills tallgrass prairie (149 territorial males/km2 VS. 25/ km2). This may be due to availability of moisture and associated density of grass stems and insect production. The bird community in the floodplain prairie however, is less diverse (5 species VS. 10 species). Grasshopper sparrows (Ammodramus savannarum) …

Long-Term Grass Dynamics Within A Mixed-Grass Prairie, Brian S. Mihlbacher, Fred E. Smeins, Gerald W. Thomas, Charles A. Taylor
Proceedings of the North American Prairie Conferences
Western portions of the Edwards Plateau are dominated by a grass mosaic which consists of a rhizomatous midgrass, tobosagrass [Hilaria mutica (Buckl.) Benth.], and two stoloniferous short grasses, common curlymesquite [Hilaria belangeri (Steud.) Nash] and buffalograss [Buchloe dactyloides (Nutt.) Engelm.]. Permanent 0.3 m x 6 m belt transects were established on three major soil series (Tobosa, Ozona. Valera) across several grazing treatments on the Texas Range Station near Barnhart, Texas, and the distribution of perennial grasses was mapped in 1951 (pre-drought), 1953 (drought), 1957 (post-drought), and 1987. Cover showed no consistent trends in relation to grazing. Total …
Extent Of Woody Vegetation On The Prairie In Eastern Nebraska, 1855-1857, Steven J. Rothenberger
Extent Of Woody Vegetation On The Prairie In Eastern Nebraska, 1855-1857, Steven J. Rothenberger
Proceedings of the North American Prairie Conferences
Early surveyors' notes from five counties bordering the Platte River in eastern Nebraska were utilized to measure the extent of original woody vegetation in this region. These data were compared to field studies from the same area made from 1979-1983, were used to determine areas of prairie-forest transition, and were used to tabulate the extent of woody vegetation in the lower Platte River Valley at the time of European settlement (1855-1857). Using a modified importance value based on relative density and relative dominance of witness trees, the highest ranking pre-settlement tree species were cottonwood [Populus eltoides Marsh. spp. monilifera …

Establishment Of Grasses On Sewage Sludge-Amended Strip Mine Spoils, Cassandra S. Rodgers, Roger C. Anderson
Proceedings of the North American Prairie Conferences
Usefulness of native prairie and domesticated grasses in re-vegetating strip mine spoil and producing biomass was examined on 30-year old, recontoured spoil banks located near Canton, Illinois. Grasses were planted in the spring and fall on strip mine spoil and spoil amended with 333 MT/ha of dry sewage sludge. By the end of the second growing season, indiangrass [Sorghastrum nutans (L.) Nash] produced more biomass than the other warm-season grasses, switchgrass (Panicum virgatum L.) and little bluestem [Schizachyrium scoparium (Michx.) Nash], on the unamended plots, and no warm-season grasses survived on the sludge amended plots. Warm-season grasses were …

The Western Prairie Fringed Orchid (Platanthera Praeclara): Monitoringa And Research, Ardell J. Bjugstad, William Fortune
Proceedings of the North American Prairie Conferences
Western prairie fringed orchid (Platanthera praeciara Sheviak and Bowles) populations at one time extended from southwestern Missouri north to northwestern Minnesota, and from eastern Iowa to the Sandhills of north central Nebraska. It is listed as endangered in Iowa and Minnesota and candidate for threatened or endangered status in Kansas, Missouri, Nebraska, North Dakota, Oklahoma, and South Dakota. The questions are, "Why has it declined in numbers?" How have uses such as mowing for hay or grazing by cattle or no use (control) affected the numbers? In 1987, permanently located individual plants were counted on the Sheyenne National Grasslands …

Executive Summary
Biological diversity refers to the variety and variability among living organisms and the ecological complexes in which they occur. Diversity can be defined as the number of different items and their relative frequency. For biological diversity, these items are organized at many levels, ranging from complete ecosystems to the chemical structures that are the molecular basis of heredity. Thus, the term encompasses different ecosystems, species, genes, and their relative abundance (OTA, 1987).
There is an ongoing, unprecedented loss of the variety as well as absolute numbers of organisms-from the smallest microorganism to the largest and most spectacular of …

Research By Bureaucracy: Hattie Plum Williams And The National Commission On Law Observance And Enforcement, 1929-1931, Michael R. Hill
Department of Sociology: Faculty Publications
This paper explores the bureaucratized research activities (1929-1931) of the National Commission on Law Observance and Enforcement (NCLOE) from the perspective of Hattie Plum Williams' sociobiographical experience. Williams was a doctoral student of George E. Howard and earned her Ph.D. in 1915 -- the ftrst doctorate in sociology awarded by the University of Nebraska. That same year, she joined the Nebraska faculty and eventually became Chair of the Department (1922-1928).2 In 1931, at age 53, this full professor was called upon be an unpaid fieldworker, gathering data according to rigid protocols stipulated by the NCLOE. Archival reconstruction of Williams' "view …
Mortality Of White-Tailed Deer In Northeastern Minnesota, Michael E. Nelson, L. David Mech
Mortality Of White-Tailed Deer In Northeastern Minnesota, Michael E. Nelson, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Abstract: Two hundred nine white-tailed deer (Odocoileus virginianus) were radiotracked in the central Superior National Forest, Minnesota, from 1973 through winter 1983-84; 85 deaths were recorded. Annual survival was 0.31 for fawns (<1.0 years old), 0.80 for yearling (1.0-2.0 years old) females, 0.41 for yearling males, 0.79 for adult (≥2.0 years old) females, and 0.47 for adult males. Monthly survival rates were high from May through December (0.94-1.00), except for yearling (0.60) and adult (0.69) bucks during the November hunting season. Most mortality occurred from January through April when gray wolf (Canis lupus) predation was an important mortality source for all cohorts. Yearlings males were most vulnerable to hunting and adult males to wolf predation.

Relationship Between Snow Depth And Gray Wolf Predation On White-Tailed Deer, Michael E. Nelson, L. David Mech
Relationship Between Snow Depth And Gray Wolf Predation On White-Tailed Deer, Michael E. Nelson, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Abstract: Survival of 203 yearling and adult white-tailed deer (Odocoileus virginianus) was monitored for 23,441 deer days from January through April 1975-85 in northeastern Minnesota. Gray wolf (Canis lupus)predation was the primary mortality cause, and from year to year during this period, the mean predation rate ranged from 0.00 to 0.29. The sum of weekly snow depths/month explained 51% of the variation in annual wolf predation rate, with the highest predation during the deepest snow.

Prehistoric Firewood Exploitation: A Case Study From The Carolinian Biotic Province, David Gordon De Fant
Prehistoric Firewood Exploitation: A Case Study From The Carolinian Biotic Province, David Gordon De Fant
Masters Theses
A case study approach is applied to the problem of prehistoric firewood selection and utilization within a heterogeneous woodland environment. Prefaced by an indepth survey of theoretical and methodological approaches relevant to understanding resource exploitation, a wood charcoal analysis of the Schwerdt site (20AE127) is presented. This analysis is then discussed in regard to environmental, preservational, and functional contexts. It is suggested that this wood charcoal assemblage represents a subtle yet pervasive pattern of firewood selectivity operating within the overt bounds of expedient procurement.
