Population isolation in separate
glacial refugia is reflected in divergence
and intraspecific differentiation
???
Absence of differenciation induced with periodical species range shifts and population mixing

Colonization history and population demography
Sakhalin and Hokkaido Islands population demography
«founder effect»• several colonizations ?• not enough time for the genetic drift ?
Sakhalin IslandHokkaido Island
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.
