Topic: Complex Response of Anthropocene Rivers to a Legacy of Stressors
Summary: Many of the world’s large river ecosystems are subject to a host of anthropogenic stressors including climate change, land-use modification, flow regulation, and disconnection of the main river channel from its adjacent floodplain. Large rivers are increasingly modified by multiple stressors that cumulatively influence these ecosystems. However, few studies explicitly explore the effects of, or responses to, multiple stressors. Furthermore, our understanding of how system-wide stressors overlap in space or time and interact with each other is lacking. To expand our knowledge of the influence of anthropogenic stressors in large rivers, we need to investigate ecosystem response at broad spatial and temporal scales, whereas most studies focus on single stressors and small scales. My research examines complex changes in ecosystem structure and function in response to a legacy of stressors on the Illinois River using multiple long-term datasets.
