THE LONG-TAILED WEASEL MUSTELA FRENATA (MAMMALIA: MUSTELIDAE) IN BAJA CALIFORNIA, MEXICO

摘要

The long-tailed weasel Mustela frenata Lichtenstein 1831 has the largest range of any mustelid in the Western Hemisphere, with a known distribution extending from southern Canada throughout the United States, Mexico, and Central America, and into northern South America. Mustela frenata occurs in a variety of habitats from alpine-artic to tropical, but does not inhabit arid biotopes or deserts. Its favored habitats include brush land and open timber, brushy borders of croplands, grasslands along creeks and lakes, and swamps (Svendsen 2003).
