Abstract
Allozyme variation in four species of Arvicanthis (Arvicanthis sp, fro m Benin, A. abyssinicus, A. blicki, and A. dembeensis from Ethiopia) w as studied by means of allozyme electrophoresis at 25 presumptive gene loci. Arvicanthis sp, showed high genetic differentiation from the th ree Ethiopian species ((D) over bar = 0.839). Conversely. little genet ic differentiation (D = 0.073) was observed between the sibling specie s A. abyssinicus and A. blicki, which are genetically more closely rel ated to each other than to A. dembeensis ((D) over bar = 0.234). This pattern is consistent with that based on chromosome rearrangements. (C ) 1997 Elsevier Science Ltd.
