Fig. 3: Temperature-regime-pair-specific thermal plasticity estimates and associated additive genetic outbreeding effect estimates for thermal plasticity (αp) among wild (W), reciprocal wild-domesticated (W × D), and domesticated (D) Atlantic salmon from three temperature regimes.
Thermal plasticity per population is represented in the upper panels by slopes between temperature-regime-specific means (observed trait scale) and in the lower panels by the corresponding slope estimates with 95% confidence intervals (proportional scale except for CTmax), whereas additive genetic outbreeding effect estimates for thermal plasticity between populations are shown in the lower panels as grey lines with light grey 95% confidence bands (also given as: αp ± standard error; P-value). Estimates are for temperature pairs with a 4 °C difference (indicated above the lower panels: C → O, optimum—cold; O → W, warm—optimum) and for the four traits of length (A; n = 3932), condition (B; n = 3932), CTmax (C; n = 538), and hct (D; n = 538). Same letters above thermal plasticity estimates in the lower panels indicate within-regime-pair comparisons with no support for differences at FDR ≤ 0.05.
