Climate change can lead to mismatches in the seasonal responses of predators and prey. During the last 30 years, the growing season for the caterpillar prey of Dutch great tits occurs earlier in the year, so that the peak of caterpillar abundance is reached before the predator chicks are at their most voracious. Nussey et al. (p. 304; see the news story by Pennisi) investigate whether the current mistiming could be restored. Phenotypic plasticity in egg-laying date would need to be both under selection and heritable, conditions that have not been demonstrated in the wild. The authors find that there is indeed heritable variation among females in their laying date plasticity, and that selection favors highly plastic females.
