Rodents are found–generally in large quantities–in an array of habitats and on each and every continent besides Antarctica.
Some rodents, such as this North American beaver with its dam of gnawed tree trunks and also the lake it has established, are deemed ecosystem engineers. While some species are typical pests for humans, rodents also Perform significant ecological roles.[2] Some rodents are thought of keystone species and ecosystem engineers inside their respective habitats.
In several species, the molars are relatively massive, intricately structured, and hugely cusped or ridged. Rodent molars are well equipped to grind food into small particles.[two] The jaw musculature is strong. The lessen jaw is thrust forward although gnawing and is also pulled backwards through chewing.[three] Gnawing uses incisors and chewing uses molars, even so, due to the cranial anatomy of rodents these feeding procedures cannot be utilised concurrently and therefore are thought of as mutually special.

There's a significant increase in the ratio of ultraviolet to noticeable mild in the morning and night twilight hrs. Numerous rodents are Energetic through twilight several hours (crepuscular exercise), and UV-sensitivity might be advantageous at these instances. Ultraviolet reflectivity is of doubtful worth for nocturnal rodents.[60]
Other attributes of rodents include things like a properly-produced pterygoid area from the skull (the pterygoid muscles, which originate Within this area, take part in the movement with the reduced jaw), an elongate glen o id fossa without postglenoid system (allowing the reduced jaw to move forwards and backwards), comprehensive zygomatic arch Along with the midportion spanned with the jugal, big paroccipital procedures, alisphenoid canal existing (but often small and difficult to see), and region in between the orbits from time to time constricted and sometimes with postorbital procedures.
Lots of shelters are utilised or created; these range between tree holes, rock crevices, or easy burrows to concealed nests over the forest ground, leaf and stick constructions in tree crowns, mounds of Lower vegetation built in aquatic environments, or advanced networks of tunnels and galleries. Rodents can be Lively all calendar year or enter intervals of dormancy or deep hibernation. Breeding time and frequency, length of gestation, and litter size change widely, but two of one of the most prolific are equally related to human beings. The brown rat (
Capybara grazing A method for dealing with seasonal loads will be to take in as much as feasible and retailer the surplus nutrients as Extra fat. Marmots try this, and will be fifty% heavier in the autumn than within the spring. They count on their Body fat reserves through their very long Winter season hibernation.
