Considering the fact that 76 per cent of rodent genera consist of just one species, A lot phylogenetic variety may very well be misplaced with a comparatively tiny amount of extinctions. Inside the absence of a lot more comprehensive familiarity with species in danger and correct taxonomy, conservation should be centered mostly on better taxa (for instance family members instead of species) and geographical scorching places.
