When adaptive plasticity reduces the mismatch between the phenotype produced and the optimum ((a)-2), there is an opportunity for directional selection can act, but we would predict a weaker evolutionary response and the rate of adaptive evolution to be slower.Both phenotypic plasticity and adaptive evolution can underlie rapid phenological shifts in response to climate change, but their relative contributions are poorly understood.The first scenario corresponds to adaptive plasticity that should lead to slow or no evolution.
