Combined impacts of climate change and industrial atmospheric emissions of sulfur and nitrogen on salmon stream ecosystems in north coastal British Columbia

 

The cumulative effects of multiple stressors resulting from human activities threaten the integrity of many aquatic ecosystems. For example, climate change is altering precipitation patterns in many north temperate regions, resulting in more extreme wet and dry periods. Air and water pollution combined with increased mineralization of soils and vegetation due to climate warming is enhancing cycles of ecologically important chemical elements, such as carbon, nitrogen, and phosphorus. Over-harvesting and habitat degradation are reducing abundances of important invertebrate and fish species. My research is focused on understanding and mitigating the impact of these multiple stressors on the services that aquatic ecosystems provide for society. I am particularly interested in the cumulative impacts of climate change combined with air and water pollution on water quality and the structure and productivity of freshwater ecosystems.
