Evolutionary history of Callosciurus squirrel species seems affected by geographical-isolation by huge rivers in Southeast Asia. Geographical isolation by rivers may have influenced phylogeographical structure between and within Callosciurus species. In Sundaland, Southeast Asia, however, phylogeographical structure within Callosciurus species may be explained by geographical isolation among islands. In a test of the effects of rivers and islands, we examined phylogeographical characteristics of C. prevostii based on mitochondrial cytochrome b gene sequences. This squirrel is distributed from peninsular Thailand to Sumatra and Borneo and adjacent small islands. We collected specimens from four geographically different populations (the Malay Peninsula,...
