Résumé :
|
To mitigate the decline of the Arabian Gazelle (Gazella arabica) in Oman, captive breeding centres and reintroduction programmes have been established. A key requirement for their success is a clear understanding of the species’ genetic diversity and taxonomic status. We therefore analysed the genetic diversity of three captive populations in Oman. Genetic profiles of 65 gazelles were assessed using mitochondrial cytochrome b (cytb), the control region (CR), and seven nuclear microsatellite markers. Interspecific comparisons based on phylogenetic analyses and median-joining networks of cytb (610 bp) confirmed that all gazelles studied in Oman belong to G. arabica. Some of the haplotypes are shared with other populations from the Arabian Peninsula. Intraspecific analyses of the first hypervariable region of the CR (299 bp) revealed high levels of both nucleotide and haplotype diversity across all three captive populations. Pairwise FST comparisons based on CR sequences indicated genetic homogeneity among populations, whereas microsatellite markers suggested weak to moderate genetic differentiation. Our results indicate high genetic diversity and genetic connectivity in the Omani Arabian Gazelle captive populations. Thus, the three captive populations represent a valuable source for reintroductions and breeding programmes in Oman.
