Stream Temperature Variability and Salmon

The July issue of Science Findings (a U.S. Forest Service Pacific Northwest Research Station publication) is devoted to salmon, stream temperature variance, and how climate change and human activities can affect natural variability. The findings indicate that the commonly used degree-day accumulation model is not sufficient to predict how organisms respond to stream temperature. Changes in how the degree days are delivered have the potential to alter the timing of life history transitions in Chinook salmon and other organisms. For more information, visit:
