Investigating The Ecology And Behavior Of The Indiana Bat And Tri-Colored Bat During Fall Swarming And Spring Staging, Mallory E. Tate
Investigating The Ecology And Behavior Of The Indiana Bat And Tri-Colored Bat During Fall Swarming And Spring Staging, Mallory E. Tate
Masters Theses
White-nose syndrome has devastated bat populations across North America since 2005. Due to declines in Indiana bat (Myotis sodalis) and tri-colored bat (Perimyotis subflavus) populations across the eastern United States, management prescriptions need to consider all seasons of these species annual cycles. However, data is severely lacking on the two seasons surrounding winter hibernation. These include fall swarming, a time period when bats are mating and preparing for hibernation, and spring staging, when bats are emerging from hibernation and preparing for spring migration. Both periods are critical for successful reproduction and survival following white-nose syndrome infection. …
Evaluation Of Benthic Fish Communities In The Clinch And Duck Rivers As Habitat Indicators For The Endangered Pygmy Madtom, Noturus Stanauli, William G. Wells, Hayden T. Mattingly
Evaluation Of Benthic Fish Communities In The Clinch And Duck Rivers As Habitat Indicators For The Endangered Pygmy Madtom, Noturus Stanauli, William G. Wells, Hayden T. Mattingly
Southeastern Fishes Council Proceedings
Identifying which species are associated with a specific endangered species can inform conservation managers about potential community associations and novel localities. The benthic fish community associated with the Pygmy Madtom (Noturus stanauli) in the Duck River has been documented through Index of Biotic Integrity (IBI) work at sites where the Pygmy Madtom has occurred by the Tennessee Valley Authority (TVA). To complement the Duck River data, we gathered benthic fish community data associated with the Pygmy Madtom in the Clinch River. We used Pflieger’s metrics of constancy and fidelity to evaluate fish associations with the Pygmy Madtom. We …
High-Resolution Timeseries Analysis Of Dynamic Geochemistry: A 27-Well Survey Of Contaminated Groundwater Downstream Of The Former S-3 Ponds, Oak Ridge, Tennessee, Emma Dixon
Masters Theses
Spatiotemporal variability of geochemistry of contaminated groundwater has large implications on overall water quality and ability to respond to remedial applications. Gaining knowledge of how geochemistry changes over time in an area can help establish response trends to changing external conditions like weather and level of contamination. In this study, a spatiotemporal survey was performed on 27 wells at the Y-12 Complex in Oak Ridge, Tennessee. This was completed to measure diurnal fluxes in geochemistry from seasonal changes and extreme weather conditions in three areas of historically different contamination levels from a single point contamination source. Measurements were gathered over …

There is a need to quantify agriculture’s potential to sequester carbon (C) to inform global approaches aimed at mitigating climate change effects. Many factors including climate, crop, soil management practices, and soil type can influence the contribution of agriculture to the global carbon cycle. The objective of this study was to investigate the C sequestration potential of conservation agriculture (CA) (defined by minimal soil disturbance, maintaining permanent soil cover, and crop rotations). This study used micrometeorological methods to measure carbon dioxide (CO2) flux from several alternative CA practices in Harare, central Zimbabwe. Micrometeorological methods can detect differences in …
