Keystone Species Notes:
-Key Stone is a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.
- Contribute to the soil and water quality.
-Species in an ecosystem (habitat) rely on each other. Contributions of the keystone species is larger to the other species contributions to the habitat. Small numbers of keystone species can be a huge impact on the environment.
-Keystone species are often predators. Predators can control distribution and population of prey species.
-The disappearance of the keystone species will create a domino effect. After the keystone species are gone, the other species will also be gone and will become extinct. The keystone species disappearance could affect other species that rely on it to survive.
-Without the keystone species, new plants/animals could come out into the habitat and push out native species.
-The theory that ecosystem balance can rely on one keystone species was established in 1969 by Robert T. Paine. His research shows that removing one species had a huge effect on the surrounding ecosystem.
-Not only carnivores can be keystone species, but herbivore can be a keystone species also.
-There are other categories of species that are crucial to the sustainability of an ecosystem: Foundation, Umbrella, and Indicator.
-Foundation Species: Plays a major role in creating or maintaining a habitat that supports other species.
-Umbrella Species: Large animal/other organism in which many other species depend. Similar to keystone species, but this species are migratory and need a large habitat.
-Grasses have more nutrients for species such as bison and elk.
