Because 76 p.c of rodent genera comprise only one species, much phylogenetic range may be misplaced with a comparatively compact variety of extinctions. Inside the absence of more thorough expertise in species at risk and precise taxonomy, conservation has to be dependent primarily on increased taxa (such as families as an alternative to species) and geographical hot spots.
