Regulation of thermal acclimation varies between generations of the short‐lived mosquitofish that developed in different environmental conditions

Summary Environmental variability and perturbations can influence population persistence. It is therefore important to understand whether and how animals can compensate for environmental variability and thereby increase resilience of natural populations. Evolutionary theory predicts that in fluctuating environments, selection should favour developmental modifiers that reduce phenotypic expression of genetic variation. The expected result is …
