An ecosystem-based approach to management: using individual behaviour to predict the indirect effects of Antarctic krill fisheries on penguin foraging
Abstract: 1. Changes in species’ abundance and distributions caused by human disturbances can ... have indirect effects on other species in a community. Although ecosystem approaches to management are ... conditions on these interactions. In this study, we extended a behavioural model used previously to ... penguin foraging success and behaviour in adjacent breeding sites. 3. Increased fishing pressure offshore ...
