Drawing of the critically endangered crimson crested smooth-furred spiny rat Though rodents will not be probably the most severely threatened buy of mammals, you can find 168 species in 126 genera which have been stated to warrant conservation focus[119] during the encounter of restricted appreciation by the general public. Considering that seventy six percent of rodent genera include only one species, much phylogenetic diversity might be missing with a relatively small range of extinctions. From the absence of much more specific knowledge of species in danger and correct taxonomy, conservation needs to be based mostly on increased taxa (which include family members instead of species) and geographical incredibly hot spots.
