Movement Ecology Of Black Bears In A Fragmented Bottomland Hardwood Habitat In Louisiana, Forrest B. Marchinton
Movement Ecology Of Black Bears In A Fragmented Bottomland Hardwood Habitat In Louisiana, Forrest B. Marchinton
Masters Theses
Twelve Louisiana black bears (Ursus americanus luteolus) were captured 18 times on a 350-km2 study area in the Tensas River Basin in northeastern Louisiana during 1992 and 1993. The study area, owned by Deltic Farm and Timber Co., Inc., consisted of 4 bottomland hardwood habitat fragments, several smaller woodlots, and extensive agricultural fields.
A total of 3,748 locations were collected on 10 radio-collared bears (4 male, 6 female). Mean home ranges were 52.33 km2 and 12.61 km2 for males and females, respectively, and were largest during the fall. Home range overlap, particularly among females, suggested …
A Repeatable, Visual Survey Of Three Rare Percina (Osteichthyes: Percidae) Fish In Little River, Blount County, Tennessee, Charles H. Heacock
A Repeatable, Visual Survey Of Three Rare Percina (Osteichthyes: Percidae) Fish In Little River, Blount County, Tennessee, Charles H. Heacock
Masters Theses
A recent apparent decline of the darter species in Little River, Blount County, Tennessee, suggested a deterioration on habitat quality was taking place. The objective of this study was to establish a baseline of the abundance and distribution of three large and easily recognized darter species (Percina aurantiaca, P. burtoni, and P. macrocephala) believed to be very pollution intolerant.
The study area included 27 river miles with 20 accessible sites which were determined by an area reconnaissance. Each site has been described, including diagrams and photographs, and was surveyed six times between July and October 1993. A review …
Population Dynamics Of Black Bears In Great Smoky Mountains National Park, Alex Brandon Coley
Population Dynamics Of Black Bears In Great Smoky Mountains National Park, Alex Brandon Coley
Masters Theses
Previous estimates of black bear (Ursus americanus) population density from Great Smoky Mountains National Park (GSMNP or Park) were low to intermediate when compared to other populations throughout the range of the species. These estimates conflicted with other research on GSMNP bears that indicated a high-density population with consistent growth from the early 1970's to the late 1980's. Thus, the focus of my research was to calculate appropriate estimates of population size and density and evaluate them with respect to trapping regime, demographic data, and hard mast production.
I determined effective study area sizes by calculating the average …
