The Phylogeography Of North American Chestnuts And Chinquapins (Castanea Mill., Fagaceae), Meagan A. Binkley
The Phylogeography Of North American Chestnuts And Chinquapins (Castanea Mill., Fagaceae), Meagan A. Binkley
Masters Theses and Doctoral Dissertations
North American Castanea Mill. (Fagaceae) consists of three morphologically variable species: Castanea dentata, Castanea pumila and Castanea ozarkensis. Taxonomy of these species has been complicated by intermediate morphology, similarity in growth habit, and putative naturally occurring hybridization where species' ranges overlap in the southeast. The main goals of the present study were to: 1) determine if genetics reflect the morphological variation observed in southeastern populations of North American Castanea, 2) explore the extent of cpDNA haplotype sharing among these taxa, and 3) map haplotype distribution in relation to morphotaxa. Finally, I wanted to use the information obtained from these analyses …
Assessment Of Exposure And Effects Associated With Polycyclic Aromatic Hydrocarbon Contamination In South Chattanooga, Tennessee, Jessica K. Leet
Assessment Of Exposure And Effects Associated With Polycyclic Aromatic Hydrocarbon Contamination In South Chattanooga, Tennessee, Jessica K. Leet
Masters Theses and Doctoral Dissertations
The southern part of Chattanooga, TN has been subject to dumping of industrial waste for over 100 years. Chattanooga Creek flows north through this area to the Tennessee River. The dumping of coal tar and other industrial waste in this area h as lead to the contamination of Chattanooga Creek and soil of the surrounding floodplains. Many polycyclic aromatic hydrocarbons (PAHs) are found in these areas, specifically the 16 PAHs the EPA and ATSDR consider to be priority pollutants. The close proximity of residents to contaminated sites in southern Chattanooga initiated an assessment of the potential human health risks. The …
The Vascular Flora Of The North Chickamauga Creek Gorge State Natural Area, Hamilton & Sequatchie Counties, Tennessee, Stacy D. Huskins
The Vascular Flora Of The North Chickamauga Creek Gorge State Natural Area, Hamilton & Sequatchie Counties, Tennessee, Stacy D. Huskins
Masters Theses and Doctoral Dissertations
The vascular flora of the North Chickamauga Creek Gorge State Natural Area (NCCG) was studied during three growing seasons from 2006 to 2008. NCCG is located in Hamilton and Sequatchie counties, Tennessee, on the eastern edge of the Cumberland Plateau. Within the study area are 2,862 hectares of eastern deciduous forest that contain 12 distinct habitat types. A survey of these habitat types over three growing seasons yielded 110 families, 329 genera, and 604 species or lesser taxa, including 238 county records. Seventy-six introduced species were found, comprising 12% of the total flora. Eleven species with either a state or …
Effects Of Exotic Invasive Vegetation On Breeding Birds Along The North Chickamauga Creek, Shannon Elaine Hatmaker
Effects Of Exotic Invasive Vegetation On Breeding Birds Along The North Chickamauga Creek, Shannon Elaine Hatmaker
Masters Theses and Doctoral Dissertations
The invasion of exotic plants into riparian areas of southeastern United States is a conservation concern not only for native plant communities, but also for wildlife. Breeding bird community structure could be particularly affected by such invasions and subsequent habitat changes as birds respond quickly to changes in habitat resources. During the 2007 breeding season, bird communities were surveyed using the line transect census method at four sites along the North Chickamauga Creek in Hamilton County, Tennessee. Two of the sites were regarded as being highly invaded by exotic understory plant species, while the other two sites remain relatively free …
Herbarium Infrastructure Development And Ecological Applications Of Specimens Using Geographic Information Systems, Ryan Joseph Miller
Herbarium Infrastructure Development And Ecological Applications Of Specimens Using Geographic Information Systems, Ryan Joseph Miller
Masters Theses and Doctoral Dissertations
Geographic Information Systems (GIS) allow for herbarium data to be used for new scientific research and also for the greater efficiency of the traditional uses of herbaria. My research uses the resources of both the herbarium at the University of Tennessee at Chattanooga (UCHT) and partnering herbaria of the Southeastern Regional Network of Expertise and Collections (SERNEC) to examine methods of incorporating new GIS technology into a functional infrastructure in order to enhance botanical research. Evaluations were performed on database and georeferencing software for use in the development of a pilot, GIS-enabled website used to query herbaria specimen information. Using …
