A major mid‐1980s shift in ecological structure of significant portions of the Southern Ocean
was partially due to the serial depletion of fish by intensive industrial fishing, rather than …

We consider how Antarctic seals may respond to changes in climate, realizing that
anthropogenic alteration of food webs will influence these responses. The species …

Uncertainty exists over the importance of Antarctic toothfish (Dissostichus mawsoni) as prey
of top predators in the Ross Sea. In this paper we assess relative weight given to direct …

Recently, Ballance et al.(2006) revived the hypothesis that cetaceans were a major force in
the structuring of Southern Ocean food webs, and suggested that they are still playing a …

We investigated intra-seasonal variation in foraging behavior of chick-rearing Adélie
penguins, Pygoscelis adeliae, during two consecutive summers at Cape Hallett …

Marine birds and mammals, which we will refer to collectively as 'top trophics'(members of
the top trophic level in marine food webs), relate to sea ice in two ways. They either have …

Parasite communities of Chionodraco hamatus were investigated from Terra Nova Bay
(Ross Sea, Antarctica) during host spawning time. Special attention was given to helminth …

New micro-technology with links to satellites has revolutionized the collection of information
on the foraging movements of marine animals, but observations of actual foraging are still …

After declining in abundance due to commercial whaling during the 20th century,
populations of the Antarctic blue whale (Balaenoptera musculus intermedia) have failed to …

Weddell seals (Leptonychotes weddellii) have proved to be an important predator of
Antarctic toothfish (Dissostichus mawsoni), and currently there is no ecosystem monitoring …
