Rodents are mammals characterized by higher and lessen pairs of at any time-growing rootless incisor enamel. Rodents are the biggest team of mammals, constituting Just about fifty percent of The category Mammalia’s approximately four,660 species. It is a list of picked rodents, arranged alphabetically by suborder and family members. (
Having said that, they've got a further pair of incisors in the higher jaw and the two orders have rather independent evolutionary histories.[111] The phylogeny of your rodents locations them while in the clades Glires, Euarchontoglires and Boreoeutheria. The cladogram down below displays the interior and outer relations of Rodentia based on a 2012 attempt by Wu et al. to align the molecular clock with paleontological details:[112] Boreoeutheria
Typical degus have a complex vocal repertoire. A lot of rodent species, specifically those who are diurnal and social, have a wide array of alarm calls which can be emitted when they perceive threats. There are each immediate and oblique advantages of undertaking this. A possible predator may quit when it knows it has been detected, or an alarm get in touch with can enable conspecifics or associated people to acquire evasive action.

This happens in species like Belding's ground squirrels and a few tree squirrel species.[sixty seven]
Simply because laboratory mice (property mice) and rats (brown rats) are here widely utilized as scientific products to further more our understanding of biology, an awesome offer has come to be acknowledged with regards to their cognitive capacities. Brown rats show cognitive bias, exactly where details processing is biased by whether they are inside of a beneficial or adverse affective point out.[seventy eight] For instance, laboratory rats properly trained to respond to a specific tone by urgent a lever to receive a reward, and to push Yet another lever in response to a distinct tone to be able to stay away from getting An electrical shock, are more likely to reply to an intermediate tone by deciding on the reward lever if they may have just been tickled (one thing they get pleasure from), indicating "a website link between the directly calculated optimistic affective condition and conclusion producing beneath uncertainty within an animal model."[seventy nine]
Unintentionally launched species of rodents tend to be regarded as being invasive and possess induced the extinction of various species, for instance island birds, the dodo remaining an example, previously isolated from land-primarily based predators.
The correlation concerning the unfold of rodents along with the demise of multituberculates is often a controversial topic, not thoroughly fixed. American and European multituberculate assemblages do drop in range in correlation With all the introduction of rodents in these areas, even so the remaining Asian multituberculates co-existed with rodents without having observable replacement going down, and in the long run each clades co-existed for at least fifteen million several years.[91]
Rodents very first arrived in Australia, by using the islands of Indonesia, all over 5 million many years in the past. The only real rodents identified over the continent are murids (family members Muridae. Currently all around sixty various species are present about the continent.
