Summary:Arabian oryx (Oryx leucoryx) is an endangered antelope that is being protected by captive breeding programs. However, the long term success of these programs mainly depends on the prudent use of molecular information for conservation management. We have used an array of seven microsatellite loci to examine the molecular diversity in a representative population of 24 captive-bred and reintroduced Arabian oryx. The locus-wise mean observed heterozygosity (0.601) was found to be comparatively higher than the mean expected heterozygosity (0.565). The specimen-wise observed heterozygosity ranged from 0.143 to 1.00 with an average of 0.60 whereas the mean d2 varied from 0.57 to 1023.428 with an average value of 223.357. The results of Shannon information index (I = 0.898) also indicated a high level of within population genetic diversity. The average gene flow was 0.298, ranging between 0.204 and 0.424 for different loci. In conclusion, the information about the extent of heterozygosity, allelic diversity and inbreeding/outbreeding depression using microsatellite markers could be of potential relevance for the management of captive breeding programs for the conservation of Arabian oryx.
