Is the Pyrenean newt (Calotriton asper) a thermoconformer? Cloacal and water temperature in two different thermal periods in a Pre-Pyrenean stream population

The results indicate that cloacal temperature depends on the water temperature, corroborating the idea that C. asper is mainly a thermoconformer, as it corresponds to an aquatic ectotherm. However, the cloacal temperature of newts was slightly higher than water temperature. In individuals in amplexus, cloacal temperature was significantly higher than in specimens that are not in amplexus, and in July, females showed much greater dispersion in cloacal temperature than males, which is probably related to spawning behaviour.
