Drawing of your critically endangered pink crested soft-furred spiny rat Although rodents are not quite possibly the most seriously threatened get of mammals, you will discover 168 species in 126 genera which are mentioned to warrant conservation consideration[119] during the deal with of minimal appreciation by the general public. Since seventy six per cent of rodent genera include only one species, Considerably phylogenetic range might be here missing with a relatively little range of extinctions. While in the absence of more thorough familiarity with species at risk and accurate taxonomy, conservation should be based mostly predominantly on higher taxa (which include family members instead of species) and geographical incredibly hot places.
