They may be favored as a consequence of their small size, fertility, quick gestation period and ease of handling and mainly because they are susceptible to lots of the problems and bacterial infections that afflict humans. They are really Utilized in investigate into genetics, developmental biology, cell biology, oncology and immunology.[137] Guinea pigs ended up preferred laboratory animals right until the late 20th century; about 2.

When making their dams and lodges, beavers change the paths of streams and rivers[26] and permit for your development of substantial wetland habitats. A single analyze located that engineering by beavers leads to a 33 percent rise in the number of herbaceous plant species in riparian parts.
Rodents generally Participate in a important part inside the communities where they Stay since they serve as prey for other mammals and birds. In this manner, They're comparable to hares, rabbits, and pikas, a bunch of mammals whose customers also serve as prey for carnivorous birds and mammals.
