Spatial Ecology Of Black Bears Prior To Construction Of A 4-Lane Highway In Eastern North Carolina, Jason Lee Kindall
Spatial Ecology Of Black Bears Prior To Construction Of A 4-Lane Highway In Eastern North Carolina, Jason Lee Kindall
Masters Theses
The North Carolina Department of Transportation is rerouting and upgrading a 19.3-km section of U.S. Highway 64 in Washington County to a 4-lane divided highway. This new section of highway bisects core black bear (Ursus americanus) habitat, potentially affecting bear habitat quality and increasing the human safety risk because of bear-vehicle collisions. The North Carolina Department of Transportation included 3 wildlife underpasses in the design of the new route to mitigate these risks. In 2000, the University of Tennessee initiated a research project to determine the short-term impacts of the new 4-lane highway on spatial ecology, population demographics, and …
Structural Changes In The Red Spruce-Fraser Fir Forest, Michael R. Mancusi
Structural Changes In The Red Spruce-Fraser Fir Forest, Michael R. Mancusi
Masters Theses
Since the early 1900s the southern Appalachian red spruce (Picea rubens Sarg.)-Fraser fir (Abies piceae (Pursh) Poir.) forests have been subjected to numerous destructive influences. Historical logging practices, fire, exotic insect infestations, acidic deposition, and global climate change have demonstratively altered the structure and composition of this fragile ecosystem. Most profound was the discovery in 1957 of the balsam woolly adelgid (Adelges piceae Ratz. Homoptera: Adelgidae ), an exotic sap-sucking aphid. A study was initiated in the Great Smoky Mountains National Park, which contains 74% of the red spruce-Fraser ecosystem. Thirty-six 20x20 m permanent plots untouched by logging …
The Effects Of Sediment And Nutrient Loading On Aquatic Organisms In Nails And Ellejoy Creeks, Blount County, Tennessee, Susanna Hannah Sutherland
The Effects Of Sediment And Nutrient Loading On Aquatic Organisms In Nails And Ellejoy Creeks, Blount County, Tennessee, Susanna Hannah Sutherland
Masters Theses
The health of an entire ecosystem is influenced by its water supply. Nonpoint source pollution, such as sediments and nutrients, cause impairment of water quality and harm aquatic diversity. This study was designed to assess the impacts of excess sediment and nutrients on aquatic health in the Nails (HUC12, 060102010105) and Ellejoy (HUC 12, 060102010104) Creeks, subwatersheds of the Little River (HUC10, 0601020101) watershed and the Watts Bar Lake watershed (HUC8, 06010201) in Blount County, Tennessee. Previous research has shown a negative correlation between these pollutants and benthic indicator species. In 2002, the 303(d) list indicated that both streams were …
