Reptiles

Florida's pine flatwoods are pyrogenic ecosystems that require frequent fires to regenerate the herbaceous layer and suppress crowding vegetation. Human development has hindered these natural fires and consequently affected the herpetofauna (amphibian and reptile) species. Anthropogenic encroachment, in addition to fire suppression, has also provided ideal habitats for invasive species within native environments. Exotic species are often found in developed areas around buildings and roads, and it is likely this pattern continues into the park. This eight-month coverboard survey focuses on the effects various fires may have on herpetofauna in the area and explores the level of intrusion exotic species exhibit within the communities. Minimal differences among herpetofauna composition between transects were found. However, a convincing percentage of exotic species were found only within the first ten meters of the transects while all native species were at least 25 meters into a transect.

Many species considered exotic, by both biological definition and social construction, have been introduced into South Florida. These species compete for resources with native species and with each other. In this study, I surveyed the John D. MacArthur Campus of Florida Atlantic University in Jupiter Florida during spring and fall of 2005 to determine the assemblage dynamics of several exotic herpetofauna species, primarily the nocturnal Wood Slave gecko (Hemidactylus mabouia), the Indo- Pacific gecko (H. garnotii), and the diurnal Cuban brown anole (Anolis sagrei). I found that the more recently established (H. mabouia) was out-competing (H. garnotii) on most of the buildings being surveyed. The study also showed that the Cuban treefrog, (Osteopilus septentrionalis) population affected the gecko populations significantly. (A. sagrei) was the primary anole found on campus, with sightings of (A. carolinensis) the native Florida green anole, being rare.
