Are penguins and seals in competition for Antarctic krill at South Georgia?
Abstract: The Antarctic fur seal and macaroni penguin are sympatric top predators that occur in ... consumers of Antarctic krill. In recent years the population of fur seals has increased whereas that of ... we test the hypothesis that the expanded fur seal population at South Georgia may have resulted in ... prevalence of krill in the diet of the two predators differed with less krill in the diet of macaroni ...

The model suggests that ... fishing mortality on both prey species and that icefish is expected to show a larger increase in biomass ... through time than grenadiers. It also suggests that a prey-suitability function is more likely than a ... the predicted population changes with available abundance data for each species to develop hypotheses ...
