Resumen:
The way in which animals use and acquire energy is fundamental to their fitness. To date, two methods have been widely used for the determination of energy expenditure in free-ranging animals: the doubly-labeled water and the heart rate methods. A recently-proposed method uses overall dynamic body acceleration (ODBA) as a proxy for energy expenditure. Although this relationship has been studied in several species, it has only been validated for animals moving in one medium. Animals that move in two, or more, media may have different correlations between ODBA and energy expenditure according to environment. We examined whether the putative relationship between ODBA and energy expenditure varied for cormorants occupying different media using the Imperial Cormorant Phalacrocorax atriceps as a model species.
