Conservation Of Terrestrial Salamanders Through Hemlock Woolly Adelgid Management In Eastern Hemlock Forests Within Great Smoky Mountains National Park, Jonathan Lawrence Cox
Conservation Of Terrestrial Salamanders Through Hemlock Woolly Adelgid Management In Eastern Hemlock Forests Within Great Smoky Mountains National Park, Jonathan Lawrence Cox
Masters Theses
Hemlock woolly adelgid (Adelges tsugae; HWA), an invasive aphid-like arthropod, was first documented on the east coast of the United States in the 1950s. HWA is an herbivore which primarily feeds at the needle base of hemlock tree species (Pinaceae: Tsuga). With no evolutionary defenses and few biotic controls, the eastern and Carolina hemlock (Tsuga canadensis and Tsuga carolinensis) serve as the primary diet of HWA in eastern North America. The invasive pest began to spread rapidly throughout the hemlock’s range causing defoliation and death of the trees within 4 – 10 years. With the …
Improving Conservation And Recreation In Environments Shared By Humans And Bats, Hannah Shapiro
Improving Conservation And Recreation In Environments Shared By Humans And Bats, Hannah Shapiro
Masters Theses
White-nose syndrome (WNS) has drastically changed how caves are managed in the United States. This disease has killed millions of bats throughout eastern North America and continues to spread westward. Since the discovery of WNS, The U.S. National Park Service (NPS) has acted to slow the spread of the disease through the development of educational programs and the deployment of decontamination measures. Despite the vast array of research on the biological and ecological aspects of bats and WNS, few studies focus on how visitor attitudes and knowledge of management strategies implemented in response to WNS impact the effectiveness of these …
From Drones To Soil Cores: Comprehensive Ecological Assessments For Enhancing Conservation Management Of Urban Forested Natural Areas, Mia T. Wavrek
From Drones To Soil Cores: Comprehensive Ecological Assessments For Enhancing Conservation Management Of Urban Forested Natural Areas, Mia T. Wavrek
Masters Theses
Urban natural areas are vegetated areas within cities that exhibit characteristics of non-urban natural areas in that they have relatively high levels of self-regulation (low or no level of management) of natural ecosystem processes and exhibit high taxonomic, genetic, and structural diversity. When these areas take the form of urban parkland, they are often managed for their social benefits to urban residents, while their ecological potential remains underutilized. Growing interest in enhancing biodiversity conservation in cities has highlighted the importance of improving the ecological planning and management of urban natural areas, particularly forested natural areas. For the variety of agencies …
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. …
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 …
