Even though some species are frequent pests for humans, rodents also Perform essential ecological roles.[2] Some rodents are considered keystone species and ecosystem engineers in their respective habitats.
These disagreements continue to be unresolved, nor have molecular scientific tests entirely fixed the problem however they may have verified the monophyly from the team and that the clade has descended from a common Paleocene ancestor. Carleton and Musser (2005) in Mammal Species of the World have provisionally adopted a five suborder method: Sciuromorpha, Castorimorpha, Myomorpha, Anomaluromorpha, and Hystricomorpha.

Interventions may possibly involve training, producing and implementing laws and polices, modifying the habitat, changing farming practices, and biological control using pathogens or predators, in addition to poisoning and trapping.
The correlation in between the spread of rodents along with the demise of multituberculates is really a controversial subject matter, not entirely fixed. American and European multituberculate assemblages do drop in diversity in correlation with the introduction of rodents in these regions, nevertheless the remaining Asian multituberculates co-existed with rodents without observable substitution taking place, and eventually both of those clades co-existed for a minimum of 15 million a long time.[91]
