Mean along-shelf transport velocity versus year from 1960 to 2010, averaged over the 30 days following estimated spawning onset dates. Negative velocities indicate down-shelf transport. Lines are estimates for individual species spawning at four potential temperature thresholds (a-d). Includes estimates where both phenological shift and range shift were significant at α < 0.05. Omits species sparse in MAB or sparse or absent in MAB after 1990 (Supplementary Table 1). Line colors indicate rate of range warming in MAB from observations in Fig. 3f.
