The Life History, Behavior, And Ecology Of Etheostoma Sagitta (Jordan And Swain), John Eldon Lowe Jr

Masters Theses

The life history, behavior, and ecology of Etheostoma sagitta (Jordan and Swain) were studied in the Cumberland River system in Tennessee. Diving equipment was utilized in making observations on macrohabitat, microhabitat, distribution, seasonal and diurnal activity, feeding behavior, migration, territoriality, associated species, competition, and population density and structure. Courtship, reproductive behavior, and diurnal activity were studied primarily in an experimental raceway. Feeding behavior and territoriality were studied in the raceway and in a 77.5-1. (20-gal.) aquarium. Parasites, longevity, age and growth, ova numbers and maturation, sex ratios, and food habitats were examined in the laboratory.

Etheostoma sagitta was found in …

Effects Of Fraser Fir Death On Population Dynamics In Southern Appalachian Boreal Ecosystems, Rex Randall Boner

Masters Theses

High elevation fir and spruce-fir forests of the Southern Appalachians were sampled in the Black Mountains, North Carolina and in the Great Smoky Mountains, Tennessee and North Carolina. Both absolute and relative data were collected on the composition of the overstory and understory strata; the ground cover stratum was sampled for relative data. Both stands infested by the balsam woolly aphid and un-infested stands were sampled to determine the effects of the opened canopy caused by the death of Fraser fir on the population dynamics of these boreal ecosystems. Comparison of stand composition and use of correlation and regression analysis …

The Density, Distribution, And Activity Patterns Of Woodchucks In Cades Cove, Great Smoky Mountains National Park, Cathy A. Taylor

Masters Theses

The purpose of this study was to delineate certain population characteristics and behavioral aspects of the woodchuck (Marmota monax) in the southeastern extremity of its range. Random quadrants from a grid system of the Cades Cove area, GSMNP, were systematically searched for active woodchuck burrow systems during the summers of 1976, 1977, and 1978. All burrow systems, topographical features, and buildings were marked on a scaled drawing and various burrow dimensions and land usage were recorded. Twice weekly between 7 July 1977 and 11 July 1978, observations were made of woodchucks to assess behavioral responses to the environment. …

The White Pine-Hardwood Vegetation Types Of The Great Smoky Mountains National Park, Harry R. Deyoung

Masters Theses

The white pine-hardwood type was described by Miller in 1938; however, subsequent researchers of the vegetation of the Great Smoky Mountains National Park have not described this type. A field study of white pine-hardwood vegetation was conducted in the Park from June to October, 1977. The objectives were to relocate and plot sample the white pine-hardwood stands to 1) group samples into vegetation types based upon the importance of white pine and its associated taxa, 2) use quantitative vegetation analysis procedures to describe the white pine-hardwood vegetation types, 3) assess the relationship of the vegetation types to environmental characteristics, 4) …
