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 …

Observed Changes In The Largemouth Bass Population Since Construction Of A New Pump Storage Reservoir At Charleston, Illinois, Lawrence B. Durham

Masters Theses

Lake Charleston, Illinois was electrofished to determine the status of the largemouth bass (Micropterus salmoides, Lacepede) population after its reconstruction into a pump storage reservoir. The changes observed were an increased rate of growth of the initial year class, increased average growth increment of older bass, and a more abundant bass population. Factors which may have influenced increased growth were decreased turbidity, alkalinity, and increased water level. There is a possibility the increase in water level led to an increase in terrestrial invertebrates as a food source, and increased spawning substrate and cover due to submerged terrestrial vegetation. …

Factors Influencing Reforestation Of Surface Mined Lands In Southern Illinois, Jill R. Medland

Masters Theses

Studies of surface coal mined lands have focused primarily on older lands mined prior to the enactment of reclamation legislation. Current laws will require extensive grading, soil replacement and revegetation. In order to more effectively reforest these lands, I have evaluated sites planted to woody species during the past decade.

The vegetational characteristics, as well as both avaian and small mammal populations of several reclaimed surface mined areas, differing in age and reclamation procedures, were compared. Success of planted trees ranged from 50 to 91% and survival varied with the species planted. There was no relationship between tree survival and …
