Fig. 3: Plasticity increases reproductive isolation, but only for pre-mating barriers.

a, Populations that were reared in a common garden environment (yellow) had lower estimates of pre-mating reproductive isolation than populations that did not pass through a common garden environment (red). b, In contrast, whether the population was reared in a common garden environment did not impact post-mating isolating barriers. Further, pre-mating isolation estimates (a) are significantly greater than post-mating isolation estimates (b). Reproductive isolation is z-transformed. k indicates the number of effects sizes extracted with the number of studies in parentheses. The thick black lines are the 95% credible intervals, and the thin black lines are the prediction intervals. Note that the precision legend is different in a and b.
