Our research combined population genetics data from microsatellite markers with data from biophysical modeling to explore associations among levels of connectivity, genetic population structure, and potential barriers to larval dispersal throughout the range of spiny lobster, Panulirus argus. The results from our large-scale population genetics study of the spiny lobster among several advective and retentive oceanographic environments throughout the Caribbean suggest that the long-lived larvae of P. argus disperse among sites throughout their range frequently enough to homogenize the genetic population structure of this species, except for a few sites where self-recruitment is enhanced by persistent offshore gyres.
