Figure 1. Rescaled thermal performance curves for swimming speed in each treatment with fitted common template shape.

Common template shape z(T) is represented by a dashed line nad the treatments by solid lines. Each thermal performance curve of a treatment (i) and temperature were standardized with respect to the estimates of height (h), location (m; T_opt), and width (w) parameters from the fit to model. Rescaled optimum temperature T_opt = 0. (see [46], [51]). Swimming z(T)  = 1.6458–0.004T²–0.00023982T³+0.000003493T⁴.
