marmotid

Marmotid refers to the members of the family Marmotidae, a group of medium- to large-sized, stocky rodents commonly known as marmots. Marmotidae is part of the order Rodentia and is native to the Northern Hemisphere, with species inhabiting mountains, tundra, and open plains across Europe, Asia, and North America. Marmots occupy burrows in alpine and subalpine habitats as well as grasslands and steppe regions, often in areas with seasonal food availability.

Physically, marmots have stout bodies, short limbs, strong claws for digging, and thick fur adapted to cold environments. They are diurnal herbivores, feeding on grasses, forbs, seeds, and roots, and may supplement their diet with insects. Their social behavior ranges from solitary to highly gregarious, depending on species, and many live in extended family colonies that share burrows and sentinel duties.

They are known for their extensive hibernation during long winters, sometimes lasting several months, while living on fat reserves built up during the active season. Alarm calls and whistles help maintain group safety. Reproduction typically occurs in spring after emergence from hibernation, with litters consisting of multiple young in many species.

Taxonomy and conservation: The best-known members belong to the genus Marmota, which includes species such as the alpine marmot and the yellow-bellied marmot. Other fossil and obscure genera have been described in the family Marmotidae. Conservation status varies by species; habitat loss, climate change, and human disturbance threaten some marmot populations, while others remain common.
