Definition
A keystone species is a species that has a disproportionately large impact on its ecosystem relative to its abundance, often playing a critical role in maintaining the structure and diversity of the community. The removal or decline of a keystone species can lead to significant changes in the ecosystem, potentially resulting in the collapse of certain ecological functions.
Summary
Keystone species are vital components of ecosystems, playing a crucial role in maintaining ecological balance. Their presence or absence can lead to significant changes in the structure and health of their environments. For example, the removal of a keystone species can result in a cascade of negative effects, impacting many other species and the overall biodiversity of the ecosystem. Understanding keystone species is essential for conservation efforts, as protecting these organisms can help preserve the intricate web of life within ecosystems. By studying their roles, we can better appreciate the importance of biodiversity and the need for sustainable practices to ensure the health of our planet's ecosystems.
