Habitat Use Of The Key Largo Woodrat (Neotoma Floridana Smalli), Lauren J. Barth
Habitat Use Of The Key Largo Woodrat (Neotoma Floridana Smalli), Lauren J. Barth
FIU Electronic Theses and Dissertations
Key Largo woodrats are an endangered subspecies with an extremely limited habitat. This study sought to understand woodrat habitat preferences in order to guide management. Woodrats build stick nests from natural and artificial materials, so nest distribution and nest occupancy were used as indicators of preference. Distribution was determined by nest surveys, and remote cameras were used to assess occupancy. Forest structure, human disturbance, nest, and animal presence metrics were also collected. More nests were found along abandoned roads than along forest transects and more artificial nests were occupied than natural nests. These findings indicate that woodrats prefer areas with …
Conservation Of Bridle Shiner (Notropis Bifrenatus) In Connecticut: Issues In Detecting An Elusive Species, Kasey C. Pregler
Conservation Of Bridle Shiner (Notropis Bifrenatus) In Connecticut: Issues In Detecting An Elusive Species, Kasey C. Pregler
Master's Theses
Bridle Shiner (Notropis bifrenatus) is apparently declining over most of its range and is currently listed as a species of concern in Connecticut. Using an occupancy modeling framework in program PRESENCE, my study compared seining and electrofishing backpack unit detection probabilities of Bridle Shiner. This research indicated the apparent decline of Bridle Shiner in the state was in part due to changes in sampling gear used for statewide surveys. Seining used 50 years ago was demonstrably more effective at capturing Bridle Shiner than the currently favored and more frequently used electrofishing gear. In light of this recent finding, …
Historical Demography And Dispersal Patterns In The Eastern Pipistrelle Bat (Perimyotis Subflavus), Alynn M. Martin
Historical Demography And Dispersal Patterns In The Eastern Pipistrelle Bat (Perimyotis Subflavus), Alynn M. Martin
Masters Theses
The recent emergence of threats to North American bat conservation has prompted increased population genetics research on high risk species. The eastern pipistrelle bat is affected by both white-nose syndrome and wind turbine mortality. However, little work has been done regarding the population structure and effective population size of this species. Using the HVI region of the mitochondria and eight microsatellite loci, I analyzed male and female structure across the sample range of P. subflavus and estimated the effective population size of their populations. Pairwise FST values indicate that there is one panmictic population based on microsatellite data, while …
