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 […]

Foraging location and range of white-chinned petrels Procellaria aequinoctialis breeding in the South Atlantic
Read more of: Foraging location and range of white-chinned petrels Procellaria aequinoctialis breeding in the South AtlanticThe foraging range and principal feeding areas of White-chinned Petrels breeding at South Georgia were determined using satellite telemetry. Foraging trips during incubation lasted 12–15 days and covered 3000–8000 km […]

Synkinematic emplacement of Lassiter Coast Intrusive Suite plutons during the Palmer Land Event: evidence for mid-Cretaceous sinistral transpression at the Beaumont Glacier in eastern Palmer Land
Read more of: Synkinematic emplacement of Lassiter Coast Intrusive Suite plutons during the Palmer Land Event: evidence for mid-Cretaceous sinistral transpression at the Beaumont Glacier in eastern Palmer LandNew structural and geochronological data from the Eastern Palmer Land Shear Zone, in the vicinity of Beaumont Glacier, provide the first evidence of dated structural control on emplacement of the […]

Influence of adult breeding experience on growth and provisioning of Wandering Albatross Diomedea exulans chicks at South Georgia
Read more of: Influence of adult breeding experience on growth and provisioning of Wandering Albatross Diomedea exulans chicks at South GeorgiaFor most seabirds, reproductive performance improves with age; in albatrosses this is thought not to be so (experience being acquired before starting breeding) but only one study (of chick growth […]
