The yellow-bellied marmot (Marmota flaviventer), also known as the rock chuck, is a large, stout-bodied ground squirrel in the marmot genus. [2] It is one of fourteen species of marmots, and is native to mountainous and semi-arid regions of southwestern Canada and western United States, including the Rocky Mountains, Sierra Nevada, and the Great Basin, often (but not exclusively) living above ...
[3] [4] In North America, on the basis of mean linear dimensions and body masses through the year, the smallest species appears to be the Alaska marmot and the largest is the Olympic marmot. [ 5 ] [ 7 ] [ 8 ] [ 6 ] Some species, such as the Himalayan marmot and Tarbagan marmot in Asia, appear to attain roughly similar body masses to the Olympic ...
Ground squirrels are rodents of the squirrel family that generally live on the ground or in burrows, rather than in trees like the tree squirrels.The term is most often used for the medium-sized ground squirrels, as the larger ones are more commonly known as marmots (genus Marmota) or prairie dogs, while the smaller and less bushy-tailed ground squirrels tend to be known as chipmunks (genus ...
This species, along with the hoary marmot, has the lowest reproductive rate of any rodent. [43] A female Olympic marmot has a litter of from one to six young (3.3 on average) in alternate years. [44] In a given year, a third of females will have a litter. [18] Half of the pups die before the following spring.

The new species was identified by its size, body shape, teeth and coloring, the study said. DNA analysis found the new species had between 1.6% and 2% genetic divergence from other slow frogs.
[6] [7] The alpine marmot is sometimes considered the heaviest squirrel species, although some other marmot species have a similar weight range, making it unclear exactly which is the largest. [6] [7] [8] Its coat is a mixture of blonde, reddish and dark gray fur. While most of the alpine marmot's fingers have claws, its thumbs have nails.
