Population genetics and relatedness in a critically endangered island raptor, Ridgway's Hawk Buteo ridgwayi

Abstract

Many island avian populations are of conservation interest because they have a higher risk of extinction than mainland populations. Susceptibility of island birds to extinction is primarily related to human induced change through habitat loss, persecution, and introduction of exotic species, in combination with genetic factors. We used microsatellite profiles from 11 loci to assess genetic diversity and relatedness in the critically endangered hawk Buteo ridgwayi endemic to the island of Hispaniola in the Caribbean.
