A keystone species is a species that has a disproportionately large effect on its natural environment relative to its abundance. The concept was introduced in 1969 by the zoologist Robert T. Paine. Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and ...
The conservation of bison in North America is an ongoing, diverse effort to bring American bison (Bison bison) back from the brink of extinction. Plains bison, a subspecies (Bison bison bison), are a keystone species in the North American Great Plains. Bison are a species of conservation concern in part because they suffered a severe population ...
Some species, called a keystone species form a central supporting hub unique to their ecosystem. [128] The loss of such a species results in a collapse in ecosystem function, as well as the loss of coexisting species. [5] Keystone species are usually predators due to their ability to control the population of prey in their ecosystem. [128]
The Eurasian beaver is a keystone species, ... where it was reintroduced in 25 countries and conservation efforts are ongoing. However, populations in Asia remain ...
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]
A cultural keystone species is one which is of exceptional significance to a particular culture or a people. Such species can be identified by their prevalence in language, cultural practices (e.g. ceremonies), traditions, diet, medicines, material items, and histories of a community. [1][2][3] These species influence social systems and culture ...
Soulé and Noss envisaged rewilding as a conservation method based on the concept of 'cores, corridors, and carnivores'. [12] The key components of rewilding incorporate large core protected areas, keystone species, and ecological connectivity based on the theory that large predators play regulatory roles in ecosystems.
The species is native to the southeastern United States. The gopher tortoise is seen as a keystone species because it digs burrows that provide shelter for at least 360 other animal species. G. polyphemus is threatened by predation and habitat destruction. Habitat degradation is the primary reason that the gopher tortoise is listed as ...
