What is a keystone species? Why is the elimination of keystone species of such concern?
Keystone species and their importance.
Keystone species are those that have an unnecessary influence on the community due to their abundance.
Through their actions and impact on the community, keystone species serve a unique and important role.
For instance, elephants are keystone species found in southern African savanna communities; they are herbivores that primarily consume woody plants. Elephants are destructive consumers, frequently uprooting, breaking, and destroying the bushes and trees they eat, which reduces their density and promotes the growth and production of grasses. While this differentiation in the composition of the plants is detrimental to the elephants, it is beneficial to other consumers (herbivores).
Keystone species cannot be restored or rehabilitated once they have been eliminated from a given area.

A keystone species is a species that has a disproportionately large impact on its ecosystem relative to its abundance. The elimination of keystone species can lead to significant disruptions in the ecosystem, including loss of biodiversity, changes in habitat structure, and potential collapse of the ecosystem due to the interdependence of species within it.

A keystone species is a species that has a disproportionately large effect on its environment relative to its abundance. Keystone species play critical roles in maintaining the structure and function of ecosystems. Their presence influences the abundance and diversity of other species within their ecosystem, as well as the physical environment itself. Keystone species may exert their influence through predation, habitat modification, or other ecological interactions.
The elimination of keystone species is of significant concern because it can have cascading effects throughout the ecosystem, leading to destabilization and potentially irreversible changes. Keystone species often have a disproportionate impact on the structure and function of their ecosystem, so their removal can result in dramatic shifts in species composition, population dynamics, and ecosystem processes. This can lead to a phenomenon known as trophic cascades, where changes in the abundance of one species trigger a series of indirect effects that propagate through multiple trophic levels.
Furthermore, keystone species are often integral to the stability and resilience of ecosystems. Their presence helps buffer against environmental disturbances and maintain ecosystem balance. Without keystone species, ecosystems may become more vulnerable to environmental changes, such as habitat loss, invasive species, or climate change. The loss of keystone species can compromise ecosystem services that are essential for human well-being, such as clean air and water, pollination, and nutrient cycling.
In summary, the elimination of keystone species can have far-reaching consequences for ecosystems, including disruptions to species interactions, alterations in ecosystem structure and function, and decreased resilience to environmental change. Protecting keystone species and their habitats is therefore crucial for preserving biodiversity, maintaining ecosystem health, and ensuring the sustainability of ecosystems for future generations.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
