SPECIES Dicrostonyx hudsonius

Author:Pallas, 1778.
Citation:Nova Spec. Quad. Glir. Ord.: 208.
Common Name:Ungava Collared Lemming
Type Locality:Canada, Labrador.
Distribution:NE Labrador, N Quebec, and Belcher Isls in Hudson Bay, Canada.
Status:IUCN Lower Risk (lc).
Comments:Unbanded karyotype resembles that of D. richardsoni (see Krohne, 1982); lack of XY-autosomal fusion believed to be primitive within the genus (Borowik and Engstrom, 1993). Relatively early origination, possibly well before the Wisconsin glaciation, proposed from collared lemming stock isolated in periglacial tundra to the southeast of the continental ice sheet (Borowik and Engstrom, 1993; Eger, 1995). Geographic and nongeographic variation evaluated by Eger (1995).
