A hallmark of environmental science is understanding how ecosystems respond to global change. Much of this research focuses on short-term ecosystem responses, such as how an ecosystem responds to a sudden onset of drought. But previous conditions can modify that response. In the same way a formative childhood experience might change how an adult responds to stress, legacy effects can change the direction or magnitude of ecosystem responses to disturbance.
