This study was initiated to provide baseline data and to determine the utility of stable isotope analysis to evaluate the foraging strategies of an opportunistic reptile predator. Stable isotope ratios of carbon and nitrogen were evaluated from multiple tissues from terrapin populations to determine spatial or temporal variations in resource use within mangrove habitats in Southern Florida. We sampled Diamondback terrapin (Malaclemys terrapin) and potential resources within mainland and island habitats, and evaluated their δ13C and δ15N values. We fit linear regression models to determine the best predictors of isotopic values for both terrapins and their prey, and SIBER analysis to examine terrapin isotopic niche...
