A bioenergetics model for estimating prey consumption by an Adélie penguin population in east Antarctica
Abstract: We developed a bioenergetics model to estimate prey consumption by the Adelie penguin ... . The model predicts prey consumption throughout the breeding season and incorporates uncertainty in ... model parameters using Monte Carlo simulation. The model was parametised with data obtained from the ... , and a year with low breeding success. On the basis of variable breeding success and the proportion of ...
