About 40% of all mammal species are rodents. They may be native to all important land masses aside from New Zealand, Antarctica, and several oceanic islands, nevertheless they've got subsequently been introduced to most of these land masses by human activity.
mammal species are rodents, and you will discover Virtually twice as a lot of rodents as you will discover bats, which make up the subsequent-most significant mammalian purchase.

Considering the fact that 76 percent of rodent genera contain only one species, A lot phylogenetic variety could possibly be dropped with a comparatively modest quantity of extinctions. In the absence of extra thorough knowledge here of species in danger and accurate taxonomy, conservation have to be based generally on higher taxa (including family members rather then species) and geographical warm spots.
