Ancient DNA supports southern survival of Richardson's collared lemming ( Dicrostonyx richardsoni) during the last glacial maximum
Abstract Collared lemmings (genus D icrostonyx ) are circumpolar A rctic arvicoline rodents associated with tundra. However, during the last glacial maximum ( LGM ), D icrostonyx lived along the southern ice margin of the L aurentide ice sheet in communities comprising both temperate and boreal spec...

This suggests a palaeoclimate south of the Laurentide ice sheet that contains elements similar to the more temperate shrub tundra characteristic of extant D . richardsoni habitat, rather than the very cold, dry tundra of the N orthern A rctic. While more data are required to determine whether or not the LGM southern population is ancestral to extant D . richardsoni , it seems most probable that the species survived the LGM in a southern refugium.
