Definitions:

Coevolution

The joint evolution of two closely interacting species; macroevolutionary pattern in which each species is a selective agent for traits of the other.

Intermediate Disturbance Hypothesis

Species richness is greatest in communities in which disturbances are moderate in their magnitude and frequency.

Pioneer Species

Pioneer species are the first to colonize previously disrupted or damaged ecosystems, starting a chain of ecological succession that leads to increased biodiversity.

Exotic Species

Species that are introduced to a new area where they do not naturally occur, often leading to ecological disruptions.
