The Arvicolinae are a subfamily of rodents that includes the voles, lemmings, and muskrats. They are most closely related to the other subfamilies in the Cricetidae. Some authorities place the subfamily Arvicolinae in the family Muridae along with all other members of the superfamily Muroidea. Some refer to the subfamily as the Microtinae or rank the taxon as a full family, the Arvicolidae.

The northern collared lemming or Nearctic collared lemming, sometimes called the Peary Land collared lemming in Canada, is a small North American lemming. At one time, it was considered to be a subspecies of the Arctic lemming. Some sources believe several other species of collared lemmings found in North America are actually subspecies of D. groenlandicus.

The grey red-backed vole or the grey-sided vole is a species of vole. An adult grey red-backed vole weighs 20-50 grams. This species ranges across northern Eurasia, including northern China, the northern Korean Peninsula, and the islands of Sakhalin and Hokkaidō. It is larger and longer-legged than the northern red-backed vole, which covers a similar range and it is also sympatric with the Norwegian lemming.
Wrangel Island is an island in the Arctic Ocean, between the Chukchi Sea and East Siberian Sea. Wrangel Island lies astride the 180° meridian. The International Date Line is displaced eastwards at this latitude to avoid the island as well as the Chukchi Peninsula on the Russian mainland. The closest land to Wrangel Island is the tiny and rocky Herald Island located 60 km (37 mi) to the east. Wrangel Island may have been the last place on earth where mammoths survived.
