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 ...
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 ...

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]
A "keystone species" is a species that "has disproportionate importance in their community." [ 8 ] Keystone species on the great plains include the bison and the prairie dog. Many other species live on the grasslands, including deer, rabbits, mice, and many types of birds.
Robert T. Paine did experiments in 1966 [9] with Pisaster ochraceus which illustrated their role as a keystone species in regulating Mytilus californianus. [10] In this study, Paine observed that biodiversity and ecosystem persistence in intertidal zones were highly dependent upon sea star presence (Ceci, 2020).
