Temperature is a critical component of freshwater ecosystems, influencing a wide range of phenomena from phenology of individuals to interactions within aquatic communities. This symposium brought together empirical data, statistical tools, and mechanistic models describing thermal regimes in aquatic systems, with the intent of determining which techniques are best equipped for understanding these regimes and...

Large watersheds of western North America provide extensive habitat for Pacific salmon species. These fish are of great cultural, ecological, and economic importance to the peoples and ecosystems of these river basins. Some of these salmon watersheds remain relatively pristine while others have experienced decades of industrial development that have eroded their connectivity and productivity.... Read More

The IMW symposium was an excellent session with 19 presentations on watershed-scale, habitat restoration effectiveness monitoring projects from throughout the Pacific Northwest and northern California. Study designs varied, with nearly all including a before-after-control-impact (BACI) design at smaller spatial scales but less than half employing a BACI design at a watershed scale or for fish...
