Grazing species such as plains bison, which is another keystone species, the pronghorn, and the mule deer have shown a proclivity for grazing on the same land used by prairie dogs. [26] Beaver dam, an animal construction which has a transformative effect on the environment. The beaver is a well known ecosystem engineer and keystone species. It ...
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]
As they suffered a severe population bottleneck, bison became a species of conservation concern and various efforts to preserve the species through protection and stewardship began. [22] The near decimation of the species unraveled fundamental ties between bison, grassland ecosystems, and Plains Indians’ cultures and livelihoods. [23]
The loss of a keystone species results in a range of dramatic cascading effects (termed trophic cascades) that alters trophic dynamics, other food web connections, and can cause the extinction of other species. [92] [93] The term keystone species was coined by Robert Paine in 1969 and is a reference to the keystone architectural feature as the ...

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.
Another common example of ecological release can occur if a disease or a competitor or a keystone species, such as a top predator, is removed from a community or ecosystem. Classical examples of this latter dynamics include population explosions of sea urchins in California's offshore kelp beds, for example, when human hunters began to kill too ...
