Systematics and Zoogeography of Sorex in the Bering Strait Area

Shrew populations on the islands in the Bering Strait region ( Sorex pribilofensis, S. jacksoni, S. hydrodromus ) were regarded as related to Sorex arcticus of the Alaskan mainland. Our data indicate that S. pribilofensis and S. jacksoni are members of the S. (Otiosorex) cinereus group, which occurs...

Description
Summary:Shrew populations on the islands in the Bering Strait region ( Sorex pribilofensis, S. jacksoni, S. hydrodromus ) were regarded as related to Sorex arcticus of the Alaskan mainland. Our data indicate that S. pribilofensis and S. jacksoni are members of the S. (Otiosorex) cinereus group, which occurs both in Alaska and eastern Siberia. Sorex hydrodromus apparently does not exist on Unalaska Island, and is a synonym of S. pribilofensis . The Holarctic evolution of the S. cinereus and S. arcticus-S. araneus groups, and their occurrence on the Bering land connection in the late Pleistocene, is discussed.
