Keystone Species in an Ecosystem
Keystone species play a crucial role in maintaining the structure and function of an ecosystem. They have a disproportionately large impact on their environment compared to their abundance.
Contributing to Ecosystem Properties
One of the defining characteristics of keystone species is their significant influence on the ecosystem properties. They may regulate the population size of other species, control invasive species, or provide essential resources that support a variety of organisms. For example, sea otters are considered a keystone species in kelp forest ecosystems because they prey on sea urchins, which in turn prevents the overgrazing of kelp beds.
Example
In the absence of keystone species, the balance within an ecosystem can be disrupted, leading to cascading effects on other species and ultimately affecting the overall health of the ecosystem. Therefore, identifying and protecting keystone species is essential for preserving biodiversity and ecosystem stability.

Keystone Species in an Ecosystem
Keystone species are those that play a crucial role in maintaining the structure and function of an ecosystem. They have a disproportionately large impact on the ecosystem compared to their abundance.
Contribution to Ecosystem Properties:
- Keystone species contribute significantly to the overall health and stability of the ecosystem. They may regulate the population sizes of other species, maintain biodiversity, or provide critical ecosystem services.
- For example, beavers are considered a keystone species because their dam-building activities create wetland habitats that support a diverse range of plant and animal species.
Indicator of Ecosystem Health:
- The presence or absence of keystone species can serve as an indicator of the health and resilience of an ecosystem. Their decline or extinction can lead to cascading effects on other species and ecosystem processes.
- For instance, the loss of sea otters in kelp forest ecosystems can result in an overabundance of sea urchins, leading to the degradation of kelp beds.
Examples of Keystone Species:
- Other examples of keystone species include predators like wolves, topsoil engineers like earthworms, and pollinators like bees.
- These species play critical roles in shaping their ecosystems and influencing the abundance and distribution of other species.
In conclusion, keystone species are essential for maintaining the balance and resilience of ecosystems. Their presence and activities have far-reaching effects on the overall functioning of the ecosystem, making them crucial for ecological stability and biodiversity.
