Schematic representation of reaction norms for corticosterone. Examples for two linear reaction norms, representing two different phenotypes (e.g., different individuals). Phenotype I shows a greater plasticity (steeper slope) in corticosterone concentrations along a given environmental gradient while phenotype II shows less plasticity (flatter slope). The two phenotypes also differ in elevation of their slopes, and in corticosterone concentrations in an average environment (when the gradient is 0; modified from [26], after [112]).
