Summary
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 becoming increasingly prevalent, they require a fuller understand-
ing of how individual behaviour determines interactions within and between species.
2. Ecological interactions involving krill are of major importance to many species
within the Antarctic. Despite extensive knowledge of the ecosystem that they occupy,
