Abstract: Coral reef populations on Florida's central east coast are located at unique boundaries that are susceptible to many anthropogenic influences including controlled freshwater discharge and agricultural runoff. Natural environmental variability is relatively high as a result of seasonal rainfall and upwelling patterns. Neither coral spawning nor gamete development have been observed at the northern end of the Florida Coral Reef Tract, therefore we hypothesize that this region may represent a population sink for many coral species. To better understand coral population connectivity of reefs in Southeast Florida, populations of the scleractinian coral Montastraea cavernosa were examined. This species' wide geographic distribution throughout the Tropical Western Atlantic and broad depth range from 3 to 100 meter depths allow comparisons of both horizontal and vertical connectivity. However, few investigations of this species have focused on southeast Florida. St. Lucie Reef near Stuart and Breakers Reef near Palm Beach represent the upper latitudinal limits for many scleractinian coral species along the Florida Coral Reef Tract. This study aims to compare microsatellite genetic markers from these reefs to understand their connectivity and determine influences of the Florida current on dispersal, recruitment, and population structure.
