I use WIKI 2 every day and almost forgot how the original Wikipedia looks like.
What we do. Every page goes through several hundred of perfecting techniques; in live mode. Quite the same Wikipedia. Just better.

Biology

Some species live in mountainous areas, such as the Alps, northern Apennines, Carpathians, Tatras, and Pyrenees in Europe; northwestern Asia; the Rocky Mountains, Black Hills, the Cascade and Pacific Ranges, and the Sierra Nevada in North America; and the Deosai Plateau in Pakistan and Ladakh in India. Other species prefer rough grassland and can be found widely across North America and the Eurasian Steppe. The similarly sized but more social prairie dog is not classified in the genus Marmota, but in the related genus Cynomys.

Marmots typically live in burrows (often within rockpiles, particularly in the case of the yellow-bellied marmot), and hibernate there through the winter. Most marmots are highly social and use loud whistles to communicate with one another, especially when alarmed.

Marmots mainly eat greens and many types of grasses, berries, lichens, mosses, roots, and flowers.

Subgenera and species

The following is a list of all Marmota species recognized by Thorington and Hoffman[1] plus the recently defined M. kastschenkoi.[2] They divide marmots into two subgenera.

Additionally, four extinct species of marmots are recognized from the fossil record:

  • Marmota arizonae, Arizona, U.S.[3]
  • Marmota minor, Nevada, U.S.[4]
  • Marmota robusta, China[citation needed]
  • Marmota vetus, Nebraska, U.S.[5]

History and etymology

Marmota primigenia fossil

Marmots have been known since antiquity. Research by the French ethnologist Michel Peissel claimed the story of the "Gold-digging ant" reported by the Ancient Greek historian Herodotus, who lived in the fifth century BCE, was founded on the golden Himalayan marmot of the Deosai Plateau and the habit of local tribes such as the Brokpa to collect the gold dust excavated from their burrows.[6]

The etymology of the term "marmot" is uncertain. It may have arisen from the Gallo-Romance prefix marm-, meaning to mumble or murmur (an example of onomatopoeia). Another possible origin is post-classical Latin, mus montanus, meaning "mountain mouse".[7]

Beginning in 2010, Alaska celebrates February 2 as "Marmot Day", a holiday intended to observe the prevalence of marmots in that state and take the place of Groundhog Day.[8]
