Given that seventy six % of rodent genera have only one species, A great deal phylogenetic range could be missing with a relatively compact range of extinctions. From the absence of a lot more comprehensive expertise in species in danger and exact taxonomy, conservation have to be based generally on greater taxa (for instance people as an alternative to species) and geographical hot places.
