Fig. 1: Temperature response of modern and early-Anthropocene S. marinoi.

a, Mean thermal performance curves of strains from the 1960s, 1990s and 2010s (green, orange and purple, respectively). Underlying thin lines show individual performance curves of 7 strains per population. Thermal performance curves were fitted as a quadratic model. Maximum growth rate denoted by µ. b–d, Mean and confidence interval (CI) of optimum temperature (Topt) (b), lower temperature limit (Tmin) (c) and maximum growth rate (µmax) (d) were estimated for each strain by bootstrapping (n = 4 replicates per strain). Overlying strain-specific responses, the mean and CI of all strains per time point and differences between time points (lowercase grey letters) are shown.
