On the genetic diversity of spiny mice (genus Acomys) and gerbils (genus Gerbillus) in the Arabian Peninsula

Using non-destructive sampling we provide further genetic characterisations for spiny mice (Acomys dimidiatus/cahirinus) and gerbils (Gerbillus sp.) in three regions in Saudi Arabia. All individuals were sequenced for a fragment of the cytochrome b gene, and compared against available conspecifics and closely related taxa. We confirm the existence of a second Acomys dimidiatus/cahirinus lineage specific to the Arabian Peninsula as seen previously. The Arabian Gerbillus nanus is shown to group with Middle Eastern rather than African conspecifics. A second cryptic Gerbillus lineage was also sampled across multiple locations, which may be an uncharacterised G. dasyurus. © 2013 Taylor & Francis.
