Keystone Species Notes
Notes:
Foundation Species: Species that play a major role in maintaining a habitat that is dependent from other species.
Umbrella Species: A large organism other species depend on, that are usually migratory and require a large habitat.
Indicator Species: Species that usually react immediately to environmental changes such as water pollution, air pollution and climate change. When the ecosystem is damaged, it will be affected and can give an early warning when it's suffering.
- Plant or animal that plays a major role in how an ecosystem functions
- A keystone specie is often a predator
- Small numbers of keystone species can be a huge impact on the environment
- Predators keeps population and distribution for a large quantity of prey species
- Without the keystone species, new plants/animals could come out into the habitat and push out native species
- A domino effect will occur if keystone species disappeared
- If they disappear then it will affect other species that rely on them to survive
- This will lead to extinction
- Without keystone species, invasive species can push out native species
- The idea that of the keystone specie originated in 1969
- Both herbivores, and carnivores can be keystone species
