Change in migration timing for salmonids in Auke Creek, AK.

<p>(a) Temporal change in median date of migration timing. The color key for the different species is located below the figures. For both panels, the error bars represent standard errors, and the dashed line separates estimates of temporal trends in migration timing from saltwater to freshwater (left side), from temporal trends in migration timing from freshwater to saltwater (right side). (b) Change in intra-annual variation in migration timing (<i>V</i>_P ) estimated from linear regression of the number of days over which each life history type migrates into or out of Auke Creek vs. year.
