A conceptual management framework for multiple stressor interactions in freshwater lakes and rivers

Summary

Freshwater ecosystems are among the most threatened on Earth. The 5 key human-caused pressures are water extraction, habitat degradation (e.g., fragmentation or chemical pollution), overexploitation of fisheries resources, aquatic invasive species, and climate change. Understanding how multiple stressors associated with these pressures interact to affect rivers, lakes, and fishes is integral to successful management and conservation. In this study, the authors review the scientific literature to examine interactions of multiple stressors on fishes in rivers and lakes. The types of interactions can vary based on the fish species, life stage, indicator, stressor magnitude, and ecosystem studied. The authors developed a conceptual Driver-Pressure-State-Impact-Response framework to map and incorporate interactions among stressors into fish and freshwater ecosystem management.
