Using preferred habitat models for chinstrap penguins (Pygoscelis antarctica) to help improve krill fisheries management during the penguin breeding season
planning. Using habitat models to understand which variables influence the distribution of predators at-sea ... can enable us to predict the distributions of un-tracked populations, and thus help to identify any ... potential threats they may face. In the Southern Ocean the expanding krill fisheries have the potential to ... impact penguin populations. We show that the distribution of chinstrap penguins can be predicted using ...
