Distributions and predator-prey interactions of macaroni penguins, Antarctic fur seals, and Antarctic krill near Bird Island, South Georgia
Examined Eudyptes chrysolophus, Arctocephalus gazella and their zooplankton prey, in particular Antarctic krill Euphausia superba in February 1986. Antarctic fur seals and macaroni penguins showed positive correlations with Antarctic krill density across a wide range of spatial scales. When the infl...
