Theory predicts that the presence of reversible thermal acclimation or fixed phenotypes depends on the predictability of future thermal conditions in a given environment. Alternatively, comparative data suggest that thermal acclimation is induced by disparate temperature cues in water and on land. We tested both predictions by examining the acclimation response in thermal sensitivity of maximal swimming and running speed in adult newts. Our results showed that complex seasonal acclimation of locomotor capacity was influenced by the disparate thermal cues rather than by the different accuracy of these cues in water and on land. Future confrontations of theory with empirical data will require more attention not only on the assumptions of adaptive thermal acclimation but also on the ecologically relevant thermal conditions during acclimation experiments.
