Resurgence Theory is a concept in ecology that explains how populations of species can recover after a decline. It suggests that certain environmental conditions, such as the availability of resources or changes in predation, can lead to a rebound in population numbers. This theory helps scientists understand the dynamics of ecosystems and the factors that influence species survival. The theory is often applied to conservation efforts, where understanding the conditions that lead to resurgence can aid in the recovery of endangered species. By studying habitat restoration, species interactions, and climate change, researchers can develop strategies to support the resurgence of vulnerable populations.
