Investigating The Role Of Long Distance Dispersal In The Response Of Stream Fishes To Urbanization, Andrea Davis
Investigating The Role Of Long Distance Dispersal In The Response Of Stream Fishes To Urbanization, Andrea Davis
Master of Science in Integrative Biology Theses
I conducted a 7-month mark-recapture study in two watersheds differing in urban impact in order to assess the role that long distance dispersal plays in the response of tolerant stream fishes to urbanization. Our two stream sites included a heavily impacted urban stream (watershed impervious surface cover ~30%) and a mildly impacted rural stream (watershed impervious surface cover ~6%). Species of interest were marked with 12mm HPT PIT tags and included a specialist, Campostoma oligolepis (n=189 urban site, 200 rural site) and a generalist, Lepomis auritus (n=136 urban site, 182 rural site). Three resampling instances for each site were conducted …
Profiling Bat Activity And Species Presence In Managed Longleaf Pine Landscapes, Margaret Hunt
Profiling Bat Activity And Species Presence In Managed Longleaf Pine Landscapes, Margaret Hunt
Master of Science in Integrative Biology Theses
Restoration of native flora or reintroduction of at-risk fauna includes management practices that while encouraging presence and proliferation of target species, may adversely affect non-focal species. An endemic ecosystem undergoing restoration within the southeastern U.S. is that of the longleaf pine (Pinus palustris). Bats inhabit key ecological niches in forest ecosystems, including the longleaf pine ecosystem, and can be indicators of ecosystem condition. This study investigated the effects of current forest management practices and landscape management history on bat species presence and activity levels within habitat undergoing longleaf pine restoration. We deployed bat detectors in two wildlife management …
