How adaptive plasticity evolves when selected against
Fig 2
Evolution of reaction norms in slow coarse-grained environments.
(A) Lack of fit (see Evaluation of reaction norms) in current (green lines) and past (blue lines) environments. Orange line indicates average plasticity in the population, dashed orange line optimal long-term plasticity. (B) Evolved reaction norms (grey lines) compared to optimal reaction norm (dashed line) at the end of the evolutionary period. Crosses indicate optima corresponding to environmental values used in the simulation. Dots indicate the phenotypes expressed for those values. The population re-adapts to the current environment after each environmental change (adaptive tracking).
