arvicolines

Arvicolines are a subfamily of rodents belonging to the family Cricetidae. This subfamily encompasses a diverse group of small mammals commonly known as voles, lemmings, and muskrats. They are characterized by their relatively short, stocky bodies, small ears, and short tails. Their fur is typically dense and soft, providing insulation in their often cold environments.

Arvicolines are found across a wide range of habitats globally, from grasslands and forests to tundra and marshes. Their diet primarily consists of vegetation, including grasses, roots, seeds, and bark, though some species may also consume insects or small invertebrates. They are known for their rapid reproduction rates, which is a key factor in their ecological success and their role as a food source for many predators.

The subfamily is divided into several tribes, each containing various genera and species. Notable examples include the tribe Arvicolini, which includes common voles, and the tribe Lemmini, which comprises lemmings. Muskrats, though often considered voles, are classified in their own tribe, Ondatrini. Arvicolines play significant roles in their ecosystems, influencing plant communities through their grazing and serving as a crucial link in the food web.
