The behavioural and physiological ecology of diving

Recent measurements of remarkable dive performances in oceanic seabirds and marine mammals suggest the use of a range of physiological and behavioural adaptations for the parsimonious use of oxygen. Access to food at different depths may be directly related to the duration of the breath-hold, and several physiological strategies may be used to extend dive duration. But there is also a growing appreciation of the importance of behavioural strategies adopted by divers to minimize the effects of physiological limitations on diving performance and to maximize access to food.
