Abstract
Metabolic scaling (i.e. size-dependence of metabolism) varies widely with temperature and locomotor activity. We here show that intraspecific changes in metabolic scaling with warming and increasing activity differ between water- and air-breathing ectothermic vertebrates. By combining evolved responses to oxygen limitation and influences of volume-related processes, our study quantitatively incorporates temperature, activity and respiration modes to explain animal energetics.image
