Description
Summary:This study presents the first comprehensive genetic analyses of common bottlenose dolphin (Tursiops truncatus) based on mitochondrial DNA and microsatellite loci in the Wider Caribbean. Live captures of bottlenose dolphins have been occurring since the turn of the 20th century in Wider Caribbean waters where little is known about their population structure and genetic diversity. In this study, blood or tissue samples were obtained from stranded or captive dolphins from nine geographic regions. One hundred fifty‐eight sequences of the mitochondrial DNA control region and nine microsatellite loci were analyzed and compared with previously published sequences. This study revealed the presence of ‘inshore’ ecotype and ‘worldwide distributed form’ haplotypes of bottlenose dolphins in Wider Caribbean waters. At the mitochondrial level, genetic differentiation between these two groups was significant (FST = 0.805, P
