Amphibians

The construction of Abacoa included an attempt to conserve the wildlife in a Greenway, a set of habitats separated from the residential and commercial areas. All of the wetlandswith in Abacoa represent artificially constructed ponds, canals, and streams first created from 1998-2004. The present study focuses on the anuran (i.e., frog and toad) populations and looks at the number of different species that have naturally colonized six differnet sites around Abacoa. Each of these sites varies in qualities that may affect the probability of breeding in that section. The quality of water is known to be less ideal as the water flows away from the headwaters and mixes with water from other sources. This study aims to determine which anuran species are found at each of these sites after nearly a decade of colonization, and how both anuran diversity and abundance correlates with water and habitat quality.

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.
