Given that 76 per cent of rodent genera contain just one species, A lot phylogenetic variety may very well be shed with a relatively smaller number of extinctions. Inside the absence of far more specific familiarity with species at risk and correct taxonomy, conservation have to be dependent predominantly on better taxa (which include households as an alternative to species) and geographical sizzling spots.
