The greater long-tailed hamster (Tscherskia triton) is a rodent native to Siberia, the Korean Peninsula, and China. It is the only member of the genus Tscherskia.
The genetic diversity of Tscherskia triton has a positive correlation to population density when using microsatellite markers.
Climate change and human activity have had an influence on the genetic variation of this species.[2]
Male greater long-tailed hamsters exhibit high aggression during both the breeding and non-breeding seasons. Female greater long-tailed hamsters mainly show aggression during the non-breeding season.[3]
