Given that 76 per cent of rodent genera have only one species, A lot phylogenetic diversity could be dropped with a comparatively small variety of extinctions. Within the absence of a lot more comprehensive understanding of species at risk and exact taxonomy, conservation have to be dependent mainly on greater taxa (which include family members as an alternative to species) and geographical hot places.
