Dicrostonyx hudsonius (Pallas 1778) View in CoL

[Mus] hudsonius Pallas 1778 , Nova Spec. Quad. Glir. Ord.: 208.

Type Locality: Canada, Labrador.

Vernacular Names: Ungava Collared Lemming.

Distribution: NE Labrador, N Quebec, and Belcher Isls in Hudson Bay, Canada.

Conservation: IUCN – Lower Risk (lc).

Discussion: 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).
