Extended Data Fig. 5: Comparison of rate of change in peak migration timing for full vs. truncated time series.

Full time series includes all years when data were collected (closed circles), whereas truncated time series includes only smolt data collected from 1999–2019 (open circles). Colours indicate species where orange = steelhead trout, green = coho, black = Chinook, vermillion = sockeye, blue = chum, light pink = odd-year pink, dark pink = even year pink salmon. Ordered by difference in change of peak from negative to positive. More information on sites is located in Supplementary Table 1.
