Lake Baikal mountain vole
The Lake Baikal mountain vole or Olkhon mountain vole is a species of rodent in the family Cricetidae. It is found principally on the Olkhon and Ogoi islands on Lake Baikal, in southern Siberia. While it was originally described as a species, Pavlinov and Rossolimo reassigned it as a subspecies of A. tuvinicus in 1987 before reinstating it as a species in 1998.
