Caloric Production Of Black Bear Foods In Great Smoky Mountains National Park, Robert Michael Inman
Caloric Production Of Black Bear Foods In Great Smoky Mountains National Park, Robert Michael Inman
Masters Theses
Understanding energetic potential of habitat patches is important for management designed to provide adequate habitat for wildlife species. Great Smoky Mountains National Park (GSMNP) has a high density of black bears that have been studied intensively from 1968-1997; habitats within the Park are relatively undisturbed, and similar vegetative cover types can be found throughout the southern Appalachian mountains. Black bear reproduction in the Park has been correlated to hard mast production, however little work has been done to assess the importance of soft mast. Geographic Information System (GIS) based habitat use models have been developed for bears in the Park, …
Fish Fauna Of The Upper Cumberland River Drainage In Tennessee, John T. Baxter
Fish Fauna Of The Upper Cumberland River Drainage In Tennessee, John T. Baxter
Masters Theses
This thesis reports the findings of an ichthyofaunal survey of the upper Cumberland River drainage in Scott, Campbell, and Claiborne counties, Tennessee. This drainage lies on the Cumberland Plateau in northeastern Tennessee and has been impacted by extensive coal mining activity in the region. Present in the drainage are five listed species of primary concern to this study, Phoxinus cumberlandensis, Ericymba buccata, Notropis rubellus rubellus, Etheostoma baileyi, and Etheostoma sagitta. An additional species found in this drainage, Etheostoma nigrum susanae, is being considered for protected status. Field work for this survey was conducted mainly during May-August 1996 and May-August …
The Effects Of Habitat Fragmentation And Factors Influencing Nest Box Use On The Southern Flying Squirrel (Glaucomys Volans) In Southern Illinois, Catherine J. Woodworth
The Effects Of Habitat Fragmentation And Factors Influencing Nest Box Use On The Southern Flying Squirrel (Glaucomys Volans) In Southern Illinois, Catherine J. Woodworth
Masters Theses
I studied the effects of habitat :fragmentation on the southern flying squirrel (Glaucomys volans) in 30 forest fragments in southern Illinois. The fragments ranged in size from 6 ha to 5264 ha, and had varying degrees of isolation. I placed 10 nest boxes in each habitat fragment and checked them monthly. I captured southern flying squirrels in 24 of the 30 fragments, and found evidence of squirrels (i.e., nests and feeding stations) in 4 additional fragments. Thus, only 2 fragments did not show any evidence of squirrel use suggesting that the southern flying squirrel may not be particularly …
Comparisons Of Genetic Variance And Physiological Responses In Two Populations Of Western Mosquitofish, Gambusia Affinis, Brett Egger
Masters Theses
The study was conducted to determine the effects of lowered genetic variance in the Western mosquitofish (Gambusia affinis) on the physiological parameters of critical thermal maximum and minimum pH. Mosquitofish were obtained from two small central Illinois ponds, Lost Pond and Shadow Pond, by seines and dip nets. Once caught, fish were returned to the laboratory and acclimated for a minimum of five days at a temperature of 27°C and a pH of 8.25. At the beginning of each experimental run, fish were subjected to the physiological experiments for determination of critical thermal maximum and minimum pH, and then measured …
Transfer Of Immunity Against Hymenolepis Diminuta Parasites In Mice, Jerome F. Atta-Fynn
Transfer Of Immunity Against Hymenolepis Diminuta Parasites In Mice, Jerome F. Atta-Fynn
Masters Theses
The potential transfer of resistance against the rat tapeworm, Hymenolepis diminuta, from adult BALB/c mice to their young, was tested by comparing the worm burdens of 24 experimentally infected pups from previously infected females to 14 experimentally infected pups from uninfected females. The mean number of worms recovered, mean weight of recovered worms and frequency of mice pups with eggs of the parasite in their feces were significantly lower in infected pups from infected mothers than in infected pups from uninfected mothers. The lower worm burden observed in the infected pups from infected mothers suggested that the resistance to …
Roost Site Selection Of The Red Bat (Lasiurus Borealis), Kenneth J. Mager
Roost Site Selection Of The Red Bat (Lasiurus Borealis), Kenneth J. Mager
Masters Theses
I monitored the roosting activity and evaluated roost site selection of red bats (Lasiurus borealis) at study sites in Coles County during the summer of 1996. Red bats were mist-netted and radio transmitters were affixed to 12 individuals. A total of 105 transmitter-days were recorded with 75 roost locations identified. The roost types consisted of eight different species of trees, prairie grass, and residential structures but the vast majority of roosts (92%) were in large, deciduous trees. The height of the roosts ranged from 0.5 to 21.4 m, but 54.7% were between 5-10 m. Movement between consecutive roosts ranged from …
