The beaver is a keystone species, increasing biodiversity in its territory through creation of ponds and wetlands. [93] As wetlands are formed and riparian habitats enlarged, aquatic plants colonize newly available watery habitat. Insect, invertebrate, fish, mammal, and bird diversities are also expanded. [94]
Beavers build dams and lodges using tree branches, vegetation, rocks and mud; they chew down trees for building material. Dams restrict water flow, and lodges serve as shelters. Their infrastructure creates wetlands used by many other species, and because of their effect on other organisms in the ecosystem, beavers are considered a keystone ...
Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some ...
Beaver, Canadian lynx, bobcat, wolverine, and snowshoe hare are all keystone species in the taiga area. These species are keystone because they have learned to adapt to the cold climate of the area and are able to survive year-round. These species survive year-round in taiga by changing fur color and growing extra fur.
How a Keystone Species Works As everyone knows, beavers build damns and lodges in stream beds. This is in order to create deeper pools, which provide them with a habitat to swim in as well as ...
The mountain beaver (Aplodontia rufa) [Note 1] is a North American rodent.It is the only living member of its genus, Aplodontia, and family, Aplodontiidae. [2] It should not be confused with true North American and Eurasian beavers, to which it is not closely related; [3] the mountain beaver is instead more closely related to squirrels, although its less-efficient renal system was thought to ...
