Growth rates with temperature-independent and -dependent $\epsilon$, for experiments on acclimated and adapted C. vulgaris populations. (A and B) Growth rates for (A) acclimated and (B) adapted populations. Light blue lines are for growth assuming a temperature-independent $\epsilon \left(\kappa \right)$, while black lines are for growth with the $\epsilon \left(T\right)$ of Fig. 2C. Vertical lines correspond to the respective $T_{\text{pk,}r}$ values. $\mathrm{\Delta }{E}_r$ (Eq. 5) was 0.53 eV and 0.64 eV for acclimated and adapted populations, respectively, corresponding to the values of $E_{\epsilon }$ (Fig. 2C) and thus in line with theoretical expectations. $\mathrm{\Delta }{T}_{\text{pk,}r}$ (Eq. 6) was $1.7\hspace{0.17em}°$C and over $8.4\hspace{0.17em}°$C for acclimated and adapted populations, respectively. Circles correspond to the means of three replicate experimental values at each growth temperature.
