Considering the fact that 76 p.c of rodent genera consist of just one species, here A great deal phylogenetic range could possibly be dropped with a relatively tiny number of extinctions. During the absence of far more comprehensive expertise in species in danger and precise taxonomy, conservation has to be based largely on bigger taxa (for example family members instead of species) and geographical very hot places.
