Stressor-response relationships and the prospective management of aquatic ecosystems

We set out a framework for interpreting S-R relationships in terms of functional forms, trajectories, thresholds and slopes. These characteristics convey information about resistance to degradation and recovery, risks of threshold exceedance, and alternate stable states. We then set out steps for implementing threshold-based management strategies, which are based on forecasting S-R relationships and carrying out preventative actions within an adaptive framework.
