Part of a special issue on the Swedish-Russian Tundra Ecology--94 expedition. Morphometric relationships of true lemmings (Lemmus) across the Eurasian Arctic based on cranial variables were studied by multiple discriminate function analysis. Samples obtained from populations in 11 sites in Russia showed that all populations comprised 4 groups: 2 island groups on the New Siberian Islands and Wrangel Island, respectively, and 2 mainland groups, designated conventionally as western and eastern with the boundary along the Lena River. Data provided a sound basis for the reestablishment of the subspecies L. sibiricus bungei in the Arctic mainland tundra; this subspecies is distributed from the eastern shore of the Lena River up to the western shore of the Kolyma River.
