Reproductive Success Of American Kestrels (Falco Sparverius) Nesting In Boxes Along An Interstate In Northeastern Tennessee., Jennifer Robertson Powers
Reproductive Success Of American Kestrels (Falco Sparverius) Nesting In Boxes Along An Interstate In Northeastern Tennessee., Jennifer Robertson Powers
Electronic Theses and Dissertations
Nest box programs provide supplemental nest sites for American Kestrels, Falco sparverius. When the availability of nest sites is a limiting factor, the addition of nest boxes can increase local breeding populations. These programs also facilitate the collection of data on breeding kestrels.
This study focuses on an American Kestrel (Falco sparverius) nest box trail along Interstate 26 in northeastern Tennessee during the breeding seasons of 1998, 1999, 2000, 2003, 2004, 2006, and 2009. Productivity measures and reproductive success of nesting birds are provided and compared to other programs. The data are analyzed across years and by …
Mapping The Dorsal Skin Pigmentation Patterns Of Two Sympatric Populations Of Ambystomatid Salamanders, Ambystoma Opacum And A. Maculatum From Northeast Tennessee., Lok Raj Pokhrel
Electronic Theses and Dissertations
Because of growing concern of habitat fragmentation and its adverse effects on salamander communities in Appalachian region, sympatric populations of ambystomatid salamanders A. opacum and A. maculatum were studied in Northeast Tennessee to address a number of questions: i) the extent of sexual size dimorphism (SSD) in both species, ii) what traits influence the dorsal skin pigmentation and how, iii) whether gender differences in developmental stability occur, and iv) the extent of phenotypic variation within each species. The findings of this study revealed SSD in both species of salamanders. The most parsimonious statistical model was developed that explained the influence …
