The beaver is a keystone species, increasing biodiversity in its territory through creation of ponds and wetlands. [1] [2] 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. [3]

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 ...
One of the most widely-understood and studied keystone species is the beaver, whose extinction in many places of the world due to over-hunting for its fur as well as human development vastly ...
A beaver dam or beaver impoundment is a dam built by beavers; it creates a pond which protects against predators such as coyotes, wolves and bears, and holds their food during winter. These structures modify the natural environment in such a way that the overall ecosystem builds upon the change, making beavers a keystone species and ecosystem ...
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 ...
WASHINGTON (Reuters) -President-elect Donald Trump cannot ignore a law requiring Chinese-based ByteDance to divest its popular short video app TikTok in the U.S. by early next year or face a ban ...
Keystone species are typically essential because of their trophic effect, while ecosystem engineers are not. As with keystone species, ecosystem engineers are not necessarily abundant. Species with greater density and large per capita effect have a more easily-noticeable effect, but less abundant species can still have a large impact.
