Temporal plankton dynamics in an oligotrophic maritime Antarctic lake
Read more of: Temporal plankton dynamics in an oligotrophic maritime Antarctic lake1 The population density, diversity and productivity of the microbial plankton in an oligotrophic maritime Antarctic lake were studied for a 15-month period between December 1994 and February 1996. 2 […]

Isolation and characterization of Campylobacter jejuni subsp. jejuni from Macaroni Penguins (Eudyptes chrysolophus) in the subantarctic region
Read more of: Isolation and characterization of Campylobacter jejuni subsp. jejuni from Macaroni Penguins (Eudyptes chrysolophus) in the subantarctic regionOn Bird Island, South Georgia, albatrosses (n = 140), penguins (n = 100), and fur seals (n = 206) were sampled for Campylobacter jejuni. C. jejuni subsp. jejuni was recovered […]

Effects of sea ice cover on the swarming behaviour of Antarctic krill,Euphausia superba
Read more of: Effects of sea ice cover on the swarming behaviour of Antarctic krill,Euphausia superbaMuch of the distribution range of Antarctic krill, Euphausia superba, is covered by permanent or seasonal sea ice. Sea ice extent has been implicated as a major factor affecting reproductive […]

Physical oceanographic conditions to the northwest of the sub-Antarctic Island of South Georgia
Read more of: Physical oceanographic conditions to the northwest of the sub-Antarctic Island of South GeorgiaOcean physics is a key aspect of the operation of island ecosystems, yet the hydrodynamics is sometimes poorly understood. A high-resolution oceanographic survey to the north of South Georgia identified […]

State-dependent fertility in pinnipeds: contrasting capital and income breeders
Read more of: State-dependent fertility in pinnipeds: contrasting capital and income breeders1. The study tested the hypothesis that the occurrence of pregnancy in mammals that are capital breeders will be most closely related to state variables that are indices of food […]

Skin temperatures during free-ranging swimming and diving in Antarctic fur seals
Read more of: Skin temperatures during free-ranging swimming and diving in Antarctic fur sealsThis study tests the hypothesis that an endothermic homeotherm should minimise heat flux in cold polar waters by minimising skin temperature. Temperature variability was measured at the surface of the […]

Digestion rate, gut passage time and absorption efficiency in the Antarctic spiny plunderfish
Read more of: Digestion rate, gut passage time and absorption efficiency in the Antarctic spiny plunderfishThe absolute gut evacuation rate (GER) (g day−1) of Harpagifer antarcticus increased with increasing ration mass, fish mass only influenced the absolute GER at a daily ration level of 0·3% […]

DSC studies of freezing in terrestrial enchytraeids (Annelida: Oligochaeta)
Read more of: DSC studies of freezing in terrestrial enchytraeids (Annelida: Oligochaeta)Specimens of six enchytraeid species from a wide range of terrestrial habitats were cooled to –25oC and rewarmed at 1oC min-1 and their cryobiological features measured by DSC. All were […]
