As rodents colonized new territories and habitats, they diversified into different types, a method named adaptive radiation. The ability to breed speedily and feed opportunistically enabled rodents to immediately adapt to a wide array of different habitats.
Drinking water rats, coypus, muskrats and beavers are rodents whose Most important method of locomotion is swimming. They've got thick, water4proof coats and several species are Outfitted with webbed feet and thick tails for shifting throughout the water.

Examination of the belly contents in the North American white-footed mouse, Generally thought of as herbivorous, showed 34% animal make a difference.[35]
The correlation among the spread of rodents as well as demise of multituberculates is usually a controversial subject matter, not absolutely fixed.

Drawing with the critically endangered pink crested gentle-furred spiny rat Although rodents usually are not essentially the most critically threatened purchase of mammals, there are 168 species in 126 genera which might be claimed to warrant conservation interest[119] within the face of restricted appreciation by the general public. Because 76 per cent of rodent genera incorporate just one species, Considerably phylogenetic diversity could possibly be lost with a relatively little range of extinctions. From the absence of much more thorough familiarity with species in danger and accurate taxonomy, conservation have to be based mostly on better taxa (like family members as an alternative to species) and geographical warm spots.
