We examined the seasonal acclimation of preferred body temperatures (Tp) in alpine newts, Ichthyosaura alpestris, subjected to the gradual increase in acclimation temperature during the winter-summer period. Both the mean and range of Tp followed the increase in mean acclimation temperature without the influence of diel temperature fluctuations. The direction and magnitude of this acclimatory capacity has the potential to seasonally decrease the absolute deviation of operative temperatures from the Tp range (the opportunity for thermoregulation). Although thermoregulation and thermal acclimation are often considered as separate, yet co-adapted adjustments to thermal heterogeneity, their combined response is employed by newts to tackle seasonal variation in a thermoregulatory-challenging aquatic environment.
