SPECIES Sorex (Otisorex) jacksoni

Author:Hall and Gilmore, 1932.
Citation:Univ. California Publ. Zool., 38: 392.
Common Name:St. Lawrence Island Shrew
Type Locality:USA, "Sevoonga, 2 miles [3.2 km] east of North Cape, St. Lawrence Island, Bering Sea, Alaska."
Distribution:Known only from St. Lawrence Isl (Bering Sea).
Status:IUCN Endangered.
Comments:Subgenus Otisorex; S. cinereus group (Demboski and Cook, 2003). Placed in the arcticus species group by Hall and Gilmore (1932) and in the cinereus species group by Hoffmann and Peterson (1967). Separated from cinereus by Junge and Hoffmann (1981). Van Zyll de Jong (1982) included leucogaster (= beringianus), portenkoi, and ugyunak in this species, but van Zyll de Jong (1991b) retained all three as distinct. Rausch and Rausch (1995) included jacksoni as a subspecies in S. cinereus based on identical karyotypes (2n = 66, FN = 70), but Demboski and Cook (2003) found a nonsister relationship between S. cinereus and S. jacksoni in their genetic analysis of the group.
