Microsatellite loci for the Siberian flying squirrel, Pteromys volans

We report the isolation and characterization of polymorphic microsatellite loci for the Siberian flying squirrel Pteromys volans. The seven most useful loci had between six and 11 alleles and expected heterozygosities ranging from 0.477 to 0.866. We also tested the utility of these loci in other squirrel species, northern flying squirrels (Glaucomys sabrinus and G. volans) and the common red squirrel (Sciurus vulgaris). Three of the Siberian flying squirrel loci were polymorphic in other squirrel species, suggesting a limited potential for cross-species use.
