The latter conclusion is supported by the phylogeography (relationship between genetic identity and geographic distribution) of the '' Paranoplocephala arctica '' species complex, a cestode parasite of '' Dicrostonyx '' spp., indicating that two subclades probably survived the LGM with their host in the Canadian High Arctic [7].

Collared lemmings ( '' Dicrostonyx '' spp.), however, apparently parallel '' C. alpina '' in exhibiting genetic differentiation principally as a consequence of the relatively recent geographic isolation of populations during the last glacial stage [39].

Lemmings (Lemmus spp. and Dicrostonyx spp.) are superdominant species during peak years of their population cycles [29] and have large effects on ecosystem processes [30].
