摘要: The Mascarene Petrel Pseudobulweria aterrima is a critically endangered seabird endemic to Reunion Island, with an extremely small population suffering several threats. Fifteen polymorphic microsatellite loci were isolated from this species analyse genetic diversity, estimate contemporary effective size, search for evidence of bottleneck and see whether results support the hypothesis that life history traits could preserve allelic diversity in populations. Results 22 individuals found grounded as consequence light pollution highlight surprisingly high absence inbreeding, size estimated at approximately 1211 probable around 10 000 generations ago. Additional studies on structure larger number samples are thus required evaluate evolutionary potential species.
