Negatives and Positives: Contaminants and Other Stressors in Aquatic Ecosystems
1Chapema Environmental Strategies Ltd, 1324 West 22nd Street, North Vancouver, BC, V7P 2G4, Canada.
Abstract:
Published research is reviewed to provide examples of both positive and negative interactions of contaminants and: climate change; habitat change; invasive and introduced species; and, eutrophication including harmful algal blooms. None of these stressor interactions results solely in negative effects. Research must shift from examining contaminants or other stressors in isolation to considering potential positive and negative effects of interactions, with the ultimate goal of providing the necessary information for the effective management of ecosystem services.
