Since seventy six per cent of rodent genera comprise only one species, A great deal phylogenetic variety can be shed with a relatively small variety of extinctions. From the absence of extra comprehensive knowledge of species at risk and accurate taxonomy, conservation need to be based generally on higher taxa (for instance people as opposed to species) and geographical warm places.
