Arctic lemmings: keystone species in a changing environment.
... Because they are food for numerous predators, one might expect that lemmings would choose habitat that minimizes the predation risk. No particularly safe environment is available to lemmings, although both brown and collared lemmings prefer land patches with protective plant cover. Collared lemmings ...
