Activity Patterns, Movement Ecology, And Habitat Utilization Of Black Bears In The Great Smoky Mountains National Park, Tennessee, Howard B. Quigley
Masters Theses
Radio-collars were fitted on 22 black bears captured on a 155 km2 study area in the northwest portion of the Great Smoky Mountains National Park, Tennessee, between June 1978 and December 1979.
Activity monitors in radio-collars indicated that bears exhibited crepuscular daily patterns of activity which were modified seasonally; activity was highest during the day in all seasons but night time activity was highest during fall. Most seasonal variations in diet patterns of activity are attributed to changes in foraging patterns. Monthly activity levels were lowest in the postdenning months of April and May and the predenning months of …

Woody Vegetation At Burgner Acres, East-Central Illinois: Composition And Changes Since 1964, Larry Philip Lehnen Jr.
Masters Theses
A comparative study was undertaken of the changes in woody vegetation of Burgner Acres during the past 18 years. This ten acre woodlot, located in east-central Illinois was surveyed using a method identical to that of a previous study. A literature review describing the composition of three general types of forests in the Grand Prairie Division of Illinois is included.
Twenty-five arborescent species are present on the study site with white ash (Fraxinus americana L.) maintaining its position as first in importance value (I.V. = relative frequency + relative density + relative dominance). Hackberry (Celtis occidentalis L.) has …
