Rodents are in a position to recognize near family by smell and This enables them to point out nepotism (preferential behavior toward their kin) in addition to stay clear of inbreeding.

Extirpation of prairie dogs may also lead to regional and native biodiversity loss, click here elevated seed depredation, as well as the institution and distribute of invasive shrubs.[23] Burrowing rodents may perhaps consume the fruiting bodies of fungi and unfold spores by means of their feces, therefore making it possible for the fungi to disperse and form symbiotic relationships Using the roots of plants (which ordinarily are not able to prosper with out them). As such, these rodents may well play a job in preserving wholesome forests.[25]
