Ecology Of Upland Snake Communities In Managed Montane Longleaf Pine Habitats Of Georgia, Miranda Gulsby
Ecology Of Upland Snake Communities In Managed Montane Longleaf Pine Habitats Of Georgia, Miranda Gulsby
Master of Science in Integrative Biology Theses
Longleaf pine ecosystem decline in the Southeast United States has led to intensive land management implementation with the goal to benefit both the ecosystem and at-risk species. Addressing at-risk snake populations in these longleaf pine ecosystems, for instance, requires understanding both community and species level ecology of snakes in these managed forests. Data for snakes in the montane (mountain) longleaf pine habitats remains unclear since management practice implementation. Currently, intensive restoration of montane longleaf pine habitats is taking place within two Wildlife Management Areas (WMA) in the Raccoon Creek Watershed of Northwest Georgia, Sheffield and Paulding Forest. These areas differ …
Evaluating In Situ Grazing Patterns Of Lytechinus Variegatus And Their Effects On Seagrass Beds Of Thalassia Testudinum, Adrianna Parson
Evaluating In Situ Grazing Patterns Of Lytechinus Variegatus And Their Effects On Seagrass Beds Of Thalassia Testudinum, Adrianna Parson
Master of Science in Integrative Biology Theses
The sea urchin Lytechinus variegatus is a known grazer of the seagrass Thalassia testudinum, and has been known to denude vast stands of seagrass beds at high densities. Outside of these denudation events, the effects of sea urchins on seagrass are poorly understood. This study examines the effects of L. variegatus on T. testudinum in situ, to understand how sea urchins are affecting seagrasses in situ. Results indicate that urchins were found in the offshore portion of the seagrass bed at densities up to 4 urchins/m2. Changes in temperature and sediment size in the bay indicate …
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 …
Assessing Feeding Preferences And Spatial Patterns Of Lagodon Rhomboides Linnaeus, Alexandria V. Lamle
Assessing Feeding Preferences And Spatial Patterns Of Lagodon Rhomboides Linnaeus, Alexandria V. Lamle
Master of Science in Integrative Biology Theses
Mesograzers have the ability to greatly mitigate the effects of eutrophication in seagrass systems. In this study we look at pinfish (Lagodon rhomboides Linnaeus) as a potential epiphytic grazer and assess feeding preferences during a transitional stage in the ontogenetic diet shift exhibited by these fish. Since pinfish are abundant in seagrass meadows in the northern Gulf of Mexico, their dietary preferences have the potential to greatly impact seagrasses in this system. Twenty-four hour feeding trials were conducted to determine pinfish preference between seagrass (Thalassia testudinum) and algal epiphytes. St. Joseph Bay, FL was also surveyed to …
