Arvicola Didelta
The water voles are large voles in the genus ''Arvicola''. They are found in both aquatic and dry habitat through Europe and much of northern Asia. A Water Vole (North America), water vole found in Western Geography of North America, North America was historically considered a member of this genus, but has been shown to be more closely related to members of the genus ''Microtus''. Head and body lengths are 12–22 cm, tail lengths are 6.5–12.5 cm, and their weights are 70–250 g. The animals may exhibit indeterminate growth. They are thick-furred and have hairy fringes on their feet that improve their swimming ability. A 2021 phylogenetic study using Mitochondrial DNA, mtDNA found that ''Arvicola'' may not belong with the rest of its namesake tribe Arvicolini, but rather forms a sister group to the tribe Lagurini.

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...
