Given that seventy six percent of rodent genera comprise only one species, A lot phylogenetic variety could possibly be lost with a comparatively tiny range of extinctions. Within the absence of extra thorough knowledge of species in danger and exact taxonomy, conservation need to be primarily based generally on greater taxa (for instance people as opposed to species) and geographical warm spots.
