are lemming population cycles changing due to winter climate?

Lemmings are small, stocky rodents primarily found in the Arctic tundra and Northern Hemisphere. Belonging to the same subfamily as voles and muskrats, these resilient creatures are essential to the Arctic food web, supporting predators like the Arctic fox and snowy owl.

In reality, lemmings exhibit when their populations become too dense. During these migrations, they may attempt to swim across large bodies of water; while they are capable swimmers, many drown due to exhaustion or panic, which observers historically misinterpreted as intentional suicide.

Lemmings are characterized by their compact bodies, short legs, and stumpy tails. They typically measure between 10 to 22 cm (4 to 7 inches) and possess long, soft fur that can range from sandy yellow to slate gray. Some species, such as the , undergo a seasonal molt, turning white in winter to provide camouflage against the snow. These rodents are well-adapted to extreme cold:
