Pattern of shape variation in the eastern African gerbils of the genus Gerbilliscus (Rodentia, Muridae): Environmental correlations and implication for taxonomy and systematics

Gerbilliscus has been in recent years the subject of new molecular and karyological investigations that shed new light on the evolutionary processes of this taxon. However, the patterns of phenotypic diversification of Gerbilliscus remain poorly understood. Furthermore, the molecular phylogenetic analyses posed new questions concerning the systematics and taxonomy of the whole genus and revealed the possible occurrence of cryptic species and hence the need to carry out a taxonomic revision.
