Evidence for an intrinsic energetic ceiling in free‐ranging kittiwakes Rissa tridactyla
Summary 1. The rate at which free‐living animals can expend energy is limited but the causes of this limitation are not well understood. Theoretically, energy expenditure may be intrinsically limited by physiological properties of the animal constraining its capacity to process energy. Alternatively...
