摘要：
A new mitochondrial DNA control region survey of the Barbados hawksbill nesting population was undertaken using larger sample sizes, reanalysis of previously reported samples, and new primers that increase the fragment length sequenced. This work revealed that haplotypes originally identified as endemic to Barbados were misread sequences. Genetic variants and a geographic subdivision on a finer scale than has previously been recorded for sea turtles were identified between the Barbados leeward and windward coasts, indicating the need for sampling at multiple sites to reveal comprehensive genetic variation at national scales. Using the updated haplotype profiles to re-estimate Barbados’ contribution to Caribbean hawksbill foraging grounds indicated a presence several-fold larger than previously calculated; a result congruent with the breeding population being one of the largest in the region.
