Population Health Of Spotted Salamanders (Ambystoma Maculatum) In Created Vernal Pools: An Integrative Approach, Alice R. Millikin
Population Health Of Spotted Salamanders (Ambystoma Maculatum) In Created Vernal Pools: An Integrative Approach, Alice R. Millikin
Graduate Theses, Dissertations, and Problem Reports
Habitat creation is an important tool for conservation to counteract habitat loss and degradation. Vernal pools are susceptible to destruction due to limited detection, protection, and regulation. These wetlands provide fishless breeding habitat for many amphibian species including spotted salamanders (Ambystoma maculatum) in eastern North America. Determining whether created vernal pool habitat is successful is often determined by demographic data of colonizing populations. I suggest that hormone levels, population genetics, and disease prevalence can improve our understanding of population health in created habitat. The goal of this dissertation was to assess the health of spotted salamander larvae in …
Wintering American Black Duck Ecology Of Central Appalachia, Sara E. Yannuzzi
Wintering American Black Duck Ecology Of Central Appalachia, Sara E. Yannuzzi
Graduate Theses, Dissertations, and Problem Reports
The American black duck (Anas rubripes) is a species of dabbling duck found only in the northeastern part of North America, and widely hunted until its decline. Since the 1950s, the total population has decreased by 53%. Habitat degradation and decline of wintering and breeding wetlands, historic overharvest, and interactions with the mallard (A. platyrhynchos) are attributed as some of the main causes of the black duck population’s decrease. Many policies and taxa- and habitat-specific joint ventures have since been created to aid in studying and improving North American wetlands and black duck populations throughout both their breeding and wintering …
