Summary: | The mammal fauna of arctic Alaska is comprised of about thirty species, most of which are widely distributed. A few of these are essentially nearctic species, having extended their range northwestward during post-Pleistocene time. The majority, however, consists of forms which are either circumboreal in their distribution, or which have closely-related palearctic counterparts-considered specifically distinct hy most North American mammalogists. Sorne of the foremost Old World workers, however, do not agree that Bering Strait constitutes a barrier which effectively separates the Old World fauna from the New. |
