Genetic structure of Rhinoceros Rock Iguanas, Cyclura cornuta, in the Dominican Republic, with insights into the impact of captive facilities and the taxonomic status of Cyclura on Mona Island

Pasachnik, Stesha A.; Colosimo, Giuliano; Carreras-De León, Rosanna; Gerber, Glenn P. (2020)

…To better understand the population structure of this species, we used a combination of mtDNA and nuclear markers to elucidate the genetic variation of wild populations across 13 sampling regions in the Dominican Republic (DR), as well as neighboring Mona Island, home to a Cyclura population of uncertain taxonomic status…. Our results suggest that the captive facilities may pose a threat to wild populations and increased regulation of these facilities is needed….
Species identification and chromosome variation of captive two-toed sloths

Steiner, Cynthia C.; Houck, Marlys L.; Ryder, Oliver A. (2010)

Two-toed sloth species, Linnaeus's and Hoffmman's, are frequent residents of zoo collections in North America….We describe here a PCR-based technique that allows species identification of two-toed sloths without requiring sequencing, by using a mitochondrial marker (COI gene) and restriction enzyme assay….
