Are humans a keystone species?

Ecologists have identified numerous keystone species, defined as organisms that have outsized ecological impacts relative to their biomass. Here we identify human beings as a higher-order or 'hyperkeystone' species that drives complex interaction chains by affecting other keystone actors across different habitats.

Are elephants a keystone species?

African elephants are a keystone species, meaning they play a critical role in their ecosystem. Also known as "ecosystem engineers," elephants shape their habitat in many ways.

  • Mutualists.

How do you identify a keystone species?

Thus, identifying keystone species in a given ecosystem may be formulated as: (1) estimating the impact on the different elements of an ecosystem resulting from a small change to the biomass of the species to be evaluated for its 'keystoneness'; and (2) deciding on the keystoneness of a given species as a function of ...

Is Coral a keystone species?

Coral reefs are one of the most biodiverse ecosystems on the planet. ... In each ecosystem there are species who have a larger impact on the ecosystem than other species. They are called keystone species.

What happens if a keystone species is removed?

Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. Keystone species have low functional redundancy. This means that if the species were to disappear from the ecosystem, no other species would be able to fill its ecological niche.

Who eats coral?

In addition to weather, corals are vulnerable to predation. Fish, marine worms, barnacles, crabs, snails and sea stars all prey on the soft inner tissues of coral polyps. In extreme cases, entire reefs can be devastated if predator populations become too high.
