Given that seventy six % of rodent genera consist of only one species, A great deal phylogenetic variety could possibly be lost with a comparatively tiny number of extinctions. During the absence of far more comprehensive expertise in species in danger and exact taxonomy, conservation has to be centered mostly on better taxa (like households rather then species) and geographical sizzling spots.
