We incubated newt eggs under three thermal regimes with varying daily amplitudes and similar means, and accordingly we measured the swimming speed of hatched larvae at three experimental temperatures, which they would normally experience in their natural habitat. Embryonic development under low and middle temperature fluctuations produced larvae with similar swimming speeds across experimental temperatures. In contrast, the most fluctuating regime induced development of phenotypes, which at 12°C swam faster than larvae developed under moderate diel fluctuations. Our results provide evidence that diel temperature fluctuations induce acclimation of thermal dependence of locomotor performance. This plastic response may act as an important pacemaker in the evolution of thermal sensitivity.
