Lemming brown

Preexposing rodents to the odor of a conspecific can alter the response to this individual when it is again encountered later, compared with responses to con-specifics whose odor is unfamiliar. For example, female brown lemmings, Lem-mus trimocrunatus, were experimentally exposed to the odor of a male. These females engaged in more contact social behavior with that now familiar male than females who had experienced odor from a different male or none at all. The males whose odor the females had experienced ejaculated more frequently than males under the other two conditions (Coopersmith and Banks, 1983). 

Three systems possibly result from at least diffuse coevolution rat kangaroos and legumes in Australia, snowshoe hares and Alaska paper birch in Alaska, and brown and collared lemmings in Arctic North America.
