isolation in separate glacial refugia is reflected in divergence and intraspecific differentiation

Sakhalin and Hokkaido Islands HISTORY OF GREY-SIDED VOLE (population demography

Hokkaido Island

Sakhalin Island

  • several colonizations ?

  • not enough time

  • for the genetic drift ?

«founder effect»

According to SRY data Islands are genetically identical, but cytochrome b analysis shows us great differences. It may be the result of more active dispersion of males compared to females.
