Stream Ecology in a Changing World: a Multi-Scale Approach to Evaluating Threats to Water Quality

Speaker: Andy Turner, Professor of Biology and Geoscience, Clarion University

Pennsylvania holds more than 80,000 miles of flowing water, ranging from small streams to large rivers. These systems are buffeted by an array of environmental challenges. An overview of the research aimed at understanding the consequences of these perturbations will be provided. The approaches span a variety of spatial scales and the need for multiple methodologies in studying ecological systems. The results show that streams and rivers are resilient to some forms of environmental change and yet sensitive to others, highlighting the importance of continued research.
