The greater long-tailed hamster (Tscherskia triton) is a rodent native to Siberia, the Korean Peninsula, and China.

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.

[3] 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.
