Considering that 76 p.c of rodent genera consist of just one species, Substantially phylogenetic range may very well be misplaced with a relatively modest range of extinctions. Within the absence of far more specific expertise in species at risk and correct taxonomy, conservation need to be centered mainly on bigger taxa (like families instead of species) and geographical sizzling spots.
