A keystone species is a species that has a disproportionate effect on its environment relative to its abundance. The presence and activities of a keystone species play a critical role in maintaining the structure and diversity of an ecosystem. Their influence can shape community interactions and affect the population dynamics of other species.
For example:
- **Predators:** Certain predators can control the population of herbivores, which in turn allows plant communities to thrive, fostering biodiversity.
- **Ecosystem Engineers:** Species like beavers or corals can modify their environment in ways that create habitats for other organisms.
- **Mutualists:** Some plants or animals may facilitate the survival of various species through mutualistic relationships (e.g., pollinators).
Removing a keystone species can lead to significant and often detrimental changes in the ecosystem, highlighting their importance in ecological balance.
