Relationship between mean acclimation ability and latitudinal extent (decimal degrees) for 16 species of salamanders at the population level (p = .0018, R 2 = .25). Acclimation ability calculated as VO 2 at 22°C acclimation—VO 2 at 14°C acclimation for the 25°C test temperature. Standard metabolic rates were weight‐corrected prior to the analysis
