dc.descriptionRhinoceros Rock Iguanas are found across Hispaniola, the Caribbean’s second largest island, in isolated pockets of low elevation xeric habitat. To better understand the population structure of this endangered species, we used mitochondrial and nuclear DNA markers to elucidate genetic variation of wild populations across the Dominican Republic (DR), as well as neighboring Mona Island, home to a Cyclura population of uncertain taxonomic status. In addition, we evaluated the origin of iguanas in poorly regulated captive facilities throughout the DR. Our data reveal high differentiation among wild populations within the DR, and the uniqueness of the Mona Island population. Management to preserve geographic genetic diversity and evolutionary potential is needed. Further, novel genetic variability found in captive facilities, resulting from interbreeding of iguanas from distinct wild populations, suggest captive facilities as currently operated pose a significant threat to the maintenance of diversity in wild populations.

Our results suggest that the captive facilities may pose a threat to wild populations and increased regulation of these facilities is needed….
