While some rodents Have got a popularity as agricultural pests or vectors of sickness, rodents usually deliver major ecological, dietary, aesthetic, and scientific values. In several habitats, They are really very abundant, and so are very important in foods webs As well as in dispersal of plant seeds.

Because 76 % of rodent genera incorporate just one species, Considerably phylogenetic range may website be lost with a relatively little range of extinctions. While in the absence of more thorough expertise in species at risk and accurate taxonomy, conservation have to be centered mainly on greater taxa (for example families in lieu of species) and geographical warm spots.
