Late Pleistocene beetle faunas of Beringia: where east met west
Abstract Aim To examine the issue of Beringian steppe‐tundra from an entomological standpoint, using fossil beetle data collected from late Pleistocene sites. Location North‐eastern Siberia (Western Beringia), the Bering Land Bridge (Central Beringia), and Alaska and the Yukon Territory (Eastern Ber...
