Abstract

There have been several earlier studies that addressed the influence of natural disturbance regimes on coral reefs. Humans alter natural disturbance regimes, introduce new stressors, and modify background conditions of reefs. We focus on how coral reef ecosystems relate to disturbance in an increasingly human-dominated environment. The concept of ecosystem resilience-thatis, the capacity of complex systems with multiple stable states to absorb disturbance, reorganize, and adapt to change-is central in this context. Instead of focusing on the recovery of certain species and populations withindisturbed sites of individual reefs, we address spatial resilience-that is, the dynamic capacity of a reef matrix to reorganize and maintain ecosystem function following disturbance. The interplay between disturbance and ecosystem resilience is highlighted. We begin the identification of spatial sources of resilience in dynamic seascapes and exemplify and discuss the relation between "ecological memory" (biological legacies, mobile link species,and support areas) and functional diversity for seascape resilience. Managing for resilience in dynamic seascapes not only enhances the likelihood ofconserving coral reefs, it also provides insurance to society by sustaining essential ecosystem services.
