Factors Influencing Brook Trout Population Dynamics And Resilience In Central Appalachian Headwater Streams, Christopher W. Schwinghamer
Factors Influencing Brook Trout Population Dynamics And Resilience In Central Appalachian Headwater Streams, Christopher W. Schwinghamer
Graduate Theses, Dissertations, and Problem Reports
Central Appalachia has a unique history of human perturbation due largely to its historical economic reliance on extractive industry and timber harvest. Legacy impacts from these historic disturbances along with contemporary stressors in the form of continued industry, changing climates, altered land use, habitat fragmentation, and introduced species can present great threats to the region’s aquatic ecosystems. Brook Trout Salvelinus fontinalis are a species that has recreational and economic importance to the communities of central Appalachia but declines in size and abundance have been observed. Given the disturbances that threaten Brook Trout populations, understanding how their populations will respond to …

Population And Migratory Ecology Of Canada Warblers (Cardellina Canadensis) In The Central Appalachian Mountains, West Virginia, Usa, Stephanie H. Augustine
Graduate Theses, Dissertations, and Problem Reports
Nearctic-Neotropical migrant birds experience a wide range of environmental conditions throughout their annual cycle; thus, it is particularly challenging to evaluate the spatial factors that may influence population growth. The Canada Warbler (Cardellina canadensis) faces substantial range-wide population declines, but little study has been conducted regarding elements occurring across the entire year that drive demographic rates. The aims of this research are (1) determine the relationship between Canada Warbler population demographic rates and environmental conditions along an elevation gradient in the central Appalachian Mountains and (2) ascertain the nonbreeding season location and migratory routes used by the central …
