The insensitivity of thermal preferences to various thermal gradient profiles in newts

Popis výsledku v původním jazyce

Thermoregulatory behaviour is affected by various biotic and abiotic factors, which may cause a substantial bias in the laboratory estimates of preferred body temperatures (Tp). We examined thermoregulatory behaviour in alpine newts, Ichthyosaura (formerly Triturus) alpestris, in both horizontal linear and vertical nonlinear thermal gradients, to evaluate the influence of disparate water temperature distribution on their thermal preferences. Newt positions in thermal gradients differed from those in constant temperatures, which indicates their thermal preferences in both experimental set ups. The mean and range of body temperatures showed similar values in both types of aquatic thermal gradients. We concluded that under a sufficiently wide range of environmental temperatures, newt thermal preferences are largely insensitive to the thermal gradient profile. This supports the suitability of Tp estimates for further experimental and comparative studies in newts.
