Habitat Utilization And Seasonal Movements Of Black Bears In The Great Smoky Mountains National Park, Patrick C. Carr Dec 1983

Habitat Utilization And Seasonal Movements Of Black Bears In The Great Smoky Mountains National Park, Patrick C. Carr

Masters Theses

A radiotelemetry study to determine seasonal movements and habitat utilization of black bears (Ursus americanus) in the Great Smoky Mountains National Park was undertaken from June 1980 to May 1982. Annual home range size in a year of poor hard mast production was 119 km2 and 13 km2 for males and females, respectively, and 36 km2 and 6 km2 in a year of good hard mast production. Bear movements were governed by seasonal food availability. Bears exhibited an affinity to summer home ranges but traveled to widely dispersed fall ranges. Seasonal range shifts were more evident …


Effect Of Age, Caloric Restriction, And Dietary Protein On Bone Composition Of Male Rats, Melany H. Looper Dec 1983

Effect Of Age, Caloric Restriction, And Dietary Protein On Bone Composition Of Male Rats, Melany H. Looper

Masters Theses

Thirty-day old male Wistar rats were fed 1 of 8 purified diets. Three groups were fed diets containing either 12, 20, or 28% casein (protein) ad libitum. Three other groups were fed diets containing 18, 30, or 42% casein with a feed intake restricted to two-thirds of that consumed by the ad libitum groups. In addition, two groups were initially fed diets containing 20% casein, then the casein level was either gradually (0.8%/month) decreased to 12% or increased to 28% by 1 year of age. At either 1 or 2 years of age, the rats were sacrificed, and their femurs …


Paleoecological Analysis Of Holocene Vegetation, Lake In The Woods, Cades Cove, Great Smoky Mountains National Park, Jean Leighton Davidson Dec 1983

Paleoecological Analysis Of Holocene Vegetation, Lake In The Woods, Cades Cove, Great Smoky Mountains National Park, Jean Leighton Davidson

Masters Theses

Lake in the Woods is a woodland hollow pond formed on colluvium at the western end of Cades Cove in the Great Smoky Mountains National Park. The modern flora of the lake is dominated by Liquidambar styraciflua and includes several species with Coastal Palin affinities--Acer rubrum variety trilobum, Woodwardia virginica, and Helianthus angustifolius. The fine-scale vegetation changes at Lake in the Woods from 6600 BP to present have been studied using the paleoecological analysis of pollen, fungal palynomorphs, and charcoal influx. Results show that the dominants of the pond changed from Liquidambar to Salix between 6600 and 6500 …

Effect Of Forage Feeding And Length Of Grain Finishing Period On Selected Performance, Carcass, And Sensory Characteristics Of Serially Slaughtered Hereford Steers Of Varying Frame Score Classifications, Henry Walker Stockley Iii Aug 1983

Effect Of Forage Feeding And Length Of Grain Finishing Period On Selected Performance, Carcass, And Sensory Characteristics Of Serially Slaughtered Hereford Steers Of Varying Frame Score Classifications, Henry Walker Stockley Iii

Masters Theses

Eighty-one Hereford steers were backgrounded on fescue-orchard grass-clover pasture and then removed after summer grazing and assigned subjective scores for frame size and muscling. Steers were then fed whole shelled corn ad libitum for 0, 28, 56, 84, 112, and 140 days on feed (DOF), evaluated for performance traits and slaughtered. Carcass data were collected then the left side of each carcass was fabricated and evaluated for various yield, quality, chemical, physical, and palatability characteristics.

Large framed steers had heavier live weights (P<.05) and were taller at the withers (P<.05) than small framed steers throughout the forage feeding phase. All frame size groups were similar in ultrasonic fat thickness measurements during forage feeding.

During grain-finishing, the large framed steers were taller (P<.05) at the withers than the small-framed cattle through 140 DOF but past 28 DOF no advantage in frame size, with respect to live weights was discovered. Live fat thickness measurements did not differ (P>.05) among frame size groups. The small framed …


Compliance Of Prenatal Patients With Dietary Instructions Prior To Blood Glucose Testing And A Comparison Of Mixed Meal Screening Tests To Glucose Load Screening Tests, Rebecca A. Walton Aug 1983

Compliance Of Prenatal Patients With Dietary Instructions Prior To Blood Glucose Testing And A Comparison Of Mixed Meal Screening Tests To Glucose Load Screening Tests, Rebecca A. Walton

Masters Theses

Three different instruction methods and their influence on selection of a breakfast test meal were studied. Subjects were 139 pregnant, Caucasian females screened for gestational diabetes by two-hour postprandial blood glucose evaluation. Macronutrient components and kilocalories of the self-selected meals were variables analyzed and compared to the nutrient pattern of a standard meal plan. The effect of varying levels of nutrients on blood glucose values was examined.

Subjects were assigned randomly to one of three groups. Subjects in Group I were given no written or verbal instructions about test meal selection but were instructed to eat breakfast. Written instructions in …


Habitat Utilization And Movement Ecology Of Black Bears In Cherokee National Forest, R. Steven Garris Aug 1983

Habitat Utilization And Movement Ecology Of Black Bears In Cherokee National Forest, R. Steven Garris

Masters Theses

Home range, movements, and habitat use of black bears in the Cherokee National Forest were monitored from June 1980 through December 1981.

In 1980, home range sizes averaged 192 km2 for male bears and 23 km2 for females, whereas the average range in 1981 for males was 60 km2 and 15 km2 for females. Larger ranges for males likely reflect a social structure that enhances reproduction. Differences in home range sizes between years was attributed to the availability and abundance of hard mast, especially acorns. Both sexes exhibited seasonal shifts in range use between summer and …

A Profile Of Panhandling Black Bears In The Great Smoky Mountains National Park, Jane Tate Jun 1983

A Profile Of Panhandling Black Bears In The Great Smoky Mountains National Park, Jane Tate

Doctoral Dissertations

A study of panhandling black bears (Ursus americanus), conducted in the Great Smoky Mountains National Park from 1976 through 1978, focused on establishing an ecological and behavioral profile of this segment of the population. Procedures included various photographic and written records.

The panhandling contingent showed a preponderance of older females and younger males. Of 392 panhandling sessions on 33 different bears, 43.9% involved aggression. Seven types of aggression were recorded and assigned numeric values based upon apparent severity. Blow vocalization and charge were the most likely to occur. Similarly, crowding by visitors was the most frequent precipitator of ursid aggression. …

Reproduction And Denning Of Black Bears In The Great Smoky Mountains, William Gregory Wathen Jun 1983

Reproduction And Denning Of Black Bears In The Great Smoky Mountains, William Gregory Wathen

Masters Theses

The reproductive biology and denning ecology of black bears were studied in the Great Smoky Mountains National Park and Cherokee National Forest. The majority of information was collected from 36 radio-instrumented females monitored from June 1980 to May 1982.

Females entered dens from 21 November to 16 January (x=20 December, n=38), and emerged from 18 March to 4 May (x=10 April, n=41), for an average denning period of 113 days. Females with newborn cubs denned significantly longer (P< 0.001) than other females. Tree denning females emerged later and remained in dens longer than others.

Twenty-five ground dens and 33 tree dens were examined. Significant differences (P< 0.005) in den utilization were observed between winters, with more tree dens being utilized during the winter of 1980-81 (79.3%) than in the winter of 1981-82 (34.5%).

Females in estrus were captured from 22 June to 12 …
