| Abstract: | Two cryptic lineages of ‘Mountain Gazelles’ have been reported based on molecular phylogenetic analyses using maternally inherited (mitochondrial) sequence markers, namely Gazella gazella in the Levant and G. arabica south of the Arava Valley into the Arabian Peninsula. Here, we provide a rigorous test for the existence of two distinct lineages based on bi-parentally inherited (nuclear microsatellite) markers. Our study confirms two genetically distinct clusters in the Levant and detected no gene-flow between them. Divergence time (inferred from a cytochrome b-based phylogeny) was approximately one MYA. Treating and breeding both lineages separately in future conservation and captive breeding programmes is highly recommended. |
