Genetic differentiation and speciation in spiny mice, Acomys.

Research output: Contribution to journalArticlepeer-review


Allozymic variation in proteins encoded by 35 loci was analyzed electrophoretically in specimens from seven localities, involving five populations of Acomys cahirinus, 2n=38; two populations of A. cahirinus, 2n=36; and three populations of A. russatus, 2n=66, each population of the latter being sympatric with A. cahirinus. The seven localities represent a general southward transect of increasing aridity from N Israel to S Sinai. The geographical patterns and climatic correlates and predictors of genic variation in Acomys in Israel and Sinai support the environmental theory of genetic variation; the genetic distances found support a speciation theory that allows for species formation with relatively minor genic change in structural genes.-from Author
