Bat House Use In Central Florida, With Emphasis On Nycticeius Humeralis And Tadarida Brasiliensis Cynocephala, Laura Seckbach Finn
Retrospective Theses and Dissertations
Bat houses and roost sites utilized by Tadarida brasiliensis and Nycticeius humeralis were studied in four central Florida counties. Temperatures were monitored in occupied roosts and in bat houses. It was determined that the presence of bats affects roost temperature. The mean temperature in the bat house that was preferred at the Seminole Community College (SCC) site was above ambient temperature a significantly greater amount of time than mean temperature in the other style houses located at that site. A colony of bats roosting in buildings on the property of SCC was successfully relocated into bat houses located .4 kilometers …

Age, Growth, And Movement Patterns Of The Atlantic Stingray, Dasyatis Sabina, In A Florida Coastal Lagoon System, Thomas Henry Schmid
Retrospective Theses and Dissertations
Age, growth rates, and patterns of movement were studied in the Atlantic stingray, Dasyatis sabina, in the Indian River lagoon system in east central Florida. Age was estimated using the growth rings on the vertebral centrum and tretacycline marking. Tetracycline injections produced clear readable rings in all pups, but failed to be incorporated into the centra of adults. Females possess more centrum rings than males, but annual periodicity could not be verified. Growth rates were determined from aquarium held pups and adults and from tagged and recaptured animals. Males appeared to reach maturity in about two years, females in slightly …
