Available data suggests that time costs caused by temperature-dependent dive frequency can be partially compensated for by adjusting the swimming speed and diving angle during dive cycle. We tested this prediction by examining the influence of temperature on the diving behaviour of the alpine newt, Triturus alpestris. The ascending speed and angle showed disparate patterns of temperature dependency, with a minor influence on travel duration. Surprisingly, at higher temperatures, the diving newts saved most of their time by restricting swimming activity in the water column during their return to the bottom and not by adjusting their ascending duration. Hence, aquatic newts have the capacity to reduce temperature-dependent time costs of aerial breathing primarily by behavioural modifications during the descending phase of the dive cycle.
