Characterization of postdive recovery using sound recordings and its relationship to dive duration, exertion, and foraging effort of southern elephant seals (Mirounga leonina)
International audience It is notoriously difficult to measure physiological parameters in cryptic free-rangingmarine mammals. However, it is critical to understand how marine mammalsmanage their energy expenditure and their diving behavior in environments wherethe predation risks are low and where s...
