Drawing from the critically endangered red crested delicate-furred spiny rat Even though rodents aren't probably the most severely threatened order of mammals, there are 168 species in 126 genera that happen to be said to warrant conservation interest[119] inside the encounter of confined appreciation by the general public. Because 76 per cent of rodent genera incorporate just one species, Substantially phylogenetic range can be dropped with a comparatively modest quantity of extinctions. Within the absence of additional thorough expertise in species at risk and correct taxonomy, conservation need to be primarily based mostly on better taxa (such as family members as an alternative to species) and geographical warm spots.
