The endemic endangered Puerto Rican boa (Chilabothrus inornatus) has faced a variety of perils in its natural habitat, making it a species of concern in recent decades. While information regarding genetic diversity in wild populations of this species is finally being accrued, an analysis of the viability and relative genetic diversity contained in captive populations is entirely unknown, which hampers efforts to develop a captive species management plan. Here we provide that analysis using an 1100bp fragment of the mitochondrial cytochrome b gene as well as nine microsatellite loci. We obtained 46 individual boas from captive populations in the United States from both private breeders and zoos. We were able to determine relatedness among individuals as well as overall genetic diversity in the captive population. We then compared these data to the same data obtained from wild populations across the island of Puerto Rico to determine genetic diversity in the captive population relative to wild lineages. These analyses provide a starting point for informed breeding decisions in captive individuals by decreasing potential for inbreeding. We hope to provide this information to facilitate stronger conservation decisions regarding this species.
