The role of fish in the Antarctic marine food web: differences between inshore and offshore waters in the southern Scotia Arc and west Antarctic Peninsula
The role of fish in the Antarctic food web in inshore and offshore waters is analysed, taking as an example the coastal marine communities of the southern Scotia Arc (South Orkney Islands and South
Mitochondrial Function in Antarctic Nototheniids with ND6 Translocation
The translocation of ND6 is interpreted as functionally neutral but the change in amino acid sequence as adaptive and supportive of cold stenothermy in Antarctic nototheniids, and an enhanced sensitivity to ocean warming can be deduced.
Seasonal aspects of the biology and diet of nearshore nototheniid fish at Potter Cove, South Shetland Islands, Antarctica
Algae were consumed regularly throughout the year and it is suggested that they are intentially eaten by the fish, rather than by accident.
Ecology of inshore notothenioid fish from the Danco Coast, Antarctic Peninsula
The hypothesis that the commercial fishery around the South Shetland Islands at the end of the 1970s was responsible for the decrease in the inshore population of G. gibberifrons in that area during the last 17 years is supported.
The role of fish as predators of krill (Euphausia superba) and other pelagic resources in the Southern Ocean
It is suggested to incorporate data on Champsocephalus gunnari from the western Atlantic sector and Dissostichus mawsoni from the Ross Sea into modelling approaches within the CCAMLR Ecosystem Monitoring Program, which are important predators of krill and fish and form key prey for top predators in each region.
Feeding selectivity in Notothenia neglecta, Nybelin, from Potter Cove, South Shetland Islands, Antarctica
A study of feeding selectivity in Notothenia neglecta Nybelin 1951, was carried out between October 1988 and January 1989 at Potter Cove, King George Island, where this is the dominant fish species.
Grazing by the Antarctic fish Notothenia coriiceps: evidence for selective feeding on macroalgae
Investigation of Notothenia coriiceps indicates that this fish feeds not only intentionally, but also selectively, on macroalgae, and preference for particular algal species is not related to associated epifaunal biomass or to associated amphipod biomass.
