With above 2000 residing species put in about 30 families, rodents are certainly the largest purchase of mammals, no less than with regard to quantity of taxa (perfectly above 40% of mammalian species belong on the purchase Rodentia!).

Considering the fact that 76 percent of rodent genera comprise just one species, A lot phylogenetic variety might be missing with a comparatively tiny range of extinctions. Inside the absence of much more detailed knowledge of species in danger and accurate taxonomy, conservation needs to be primarily based mostly on bigger taxa (such as people in lieu of species) and geographical very hot places.
