067 Ecological Resilience, Non-linear Community Dynamics and Reversibility of State Shifts in Aquatic Ecosystems

This session will focus on advances in our understanding of ecological resilience that are derived from empirical studies of marine, estuarine and freshwater ecosystems. In an ecological context, resilience broadly refers to the capacity of an ecosystem to absorb perturbations without switching to a persistent alternative community state that is governed by a different set of stabilizing feedbacks. For communities that remained qualitatively unchanged by a disturbance, the speed at which the system returns to its pre-disturbed state is a measure of local stability. When abrupt state transitions do occur, among the important scientific and management issues are indicators of impending change (early warning, location of the system relative to tipping point), reversibility of the shift (hysteresis in the driver – response relationship, evidence for multiple domains of attraction), and processes that foster or prevent self-reinforcing alternative community states (including feedbacks between the natural and social systems). The goal of this session is to bring together aquatic scientists to share their empirical approaches to and findings on these important but poorly resolved issues in aquatic ecosystems.
