1 Subsets used to perform the calculations: thorax (T) or abdomen (A) per temperature (17°C or 28°C) for within-environment parameters, and raw slope of the reaction norm (RN) for plasticity parameters.
2 Minimum and maximum size mean value (in mm) or minimum and maximum slope of the reaction norm.
3 Minimum and maximum coefficient of variation.
4 Broad-sense heritability estimates (see S1 Table for the variance components used to estimate heritability values).
5 Results of the statistical models used to test for the effect of genotype on size (model lm (Size ~ Genotype); per body part and temperature) or the interaction between genotype and temperature on size (model lm (Size ~ Genotype*Temperature); per body part).
