The divergence of Glires, a clade consisting of rodents and lagomorphs (rabbits, hares and pikas), from other placental mammals occurred within a handful of million years once the Cretaceous-Paleogene boundary; rodents and lagomorphs then radiated in the Cenozoic.
Rodents are known for staying prolific breeders. This check here has enabled them to colonize numerous habitats and Develop up significant populations.
While some rodents have a name as agricultural pests or vectors of sickness, rodents on the whole provide important ecological, dietary, aesthetic, and scientific values. In lots of habitats, They are really really ample, and therefore are essential in foods webs As well as in dispersal of plant seeds.
About forty% of all mammal species are rodents. These are native to all big land masses apart from New Zealand, Antarctica, and several other oceanic islands, though they have got subsequently been introduced to most of these land masses by human exercise.

While in the Patagonian mara, young also are placed in communal warrens, but moms don't allow kids besides their very own to nurse.[seventy one]
Extirpation of prairie pet dogs may also contribute to regional and native biodiversity loss, greater seed depredation, and also the institution and distribute of invasive shrubs.[23] Burrowing rodents might eat the fruiting bodies of fungi and spread spores as a result of their feces, thereby letting the fungi to disperse and sort symbiotic interactions Using the roots of plants (which commonly are not able to prosper without the need of them).
