Abstract:
The American crocodile (Crocodylus acutus) in Florida is a large, upper trophic level predator that was recently down listed by the United States Fish and Wildlife Service to threatened due to an increase in number of individuals and nests. In Florida, prime habitat of the American crocodile, the South Florida estuary, is expected to incur changes due to Everglades restoration and global climate change. These changes will potentially affect the distribution, growth, survival and spatial patterns of American crocodiles. Understanding different movement tactics and habitat use patterns on highly mobile top predators allows for a greater understanding of the interactions between top predators and the habitats they prefer. Here I used satellite telemetry to determine the current spatial requirements and movement patterns. Satellite transmitters were deployed on fifteen adult female American crocodiles from December 2010 to December 2012. Kernel density estimates were used to calculate home range and core areas. Mean overall home ranges were 66.8 +/- 33.3 (SD) km2 and mean core areas were 14.2 +/- 7.2 (SD) km2. Average daily distance moved for crocodiles was greater than 1.0km. Salinity, one of the environmental parameters most likely to change due to Everglades restoration and global climate change, influenced crocodile's movement patterns. As the American crocodile in Florida continues to recover and expand into its historic range and the environment undergoes potentially dramatic changes, understanding how crocodiles will spatially respond to these potentially dramatic changes is an important step.
