Since mitochondrial DNA (mtDNA) are maternally inherited without recombination, geographic distribution of mtDNA in semiterrestrial cercopithecines is considered to be influenced by female philopatry. I examined the effect of sex difference in migration patterns on geographic distribution in a habitat whose environment has changed frequently. I investigated ten groups (n = 77) of grivets (Cercopithecus aethiops aethiops) along a 600-km stretch of the Awash River, Ethiopia. I examined the mtDNA distribution among natural local populations whose nuclear variation was already shown to have a widely homogeneous distribution. RFLP analysis of whole mtDNA genome using 17 enzymes identified ten haplotypes in five clusters (haplogroups). Sequence divergence within haplogroups ranged from 0.17%-0.38%, while divergence between haplogroups ranged between 1.0%-2.5%. Haplogroups were distributed in blocks which ranged from 120-250 km along the Awash River. The haplotype distribution pattern of males indicated that they migrate between the boundaries of these blocks. Moreover, a clumped distribution pattern suggests the history of matrilineal distribution by group fission and geographic expansion.
