Pre-natal investment in reproduction by female Antarctic fur seals
Read more of: Pre-natal investment in reproduction by female Antarctic fur sealsMaternal investment, in terms of pup birth mass, in gestation by Antarctic fur seals (Arctocephalus gazella) was related to the date of birth in two consecutive years. There were significant […]

Carbon dioxide exchange of two ecodemes of Schistidium antarctici in Continental Antarctica
Read more of: Carbon dioxide exchange of two ecodemes of Schistidium antarctici in Continental AntarcticaSchistidium antarctici is the commonest of five bryophytes known in the Windmill Islands area of Wilkes Land, Greater Antarctica. In moist habitats it forms closed carpets, but in dry sites […]

Calanoid copepods from South Georgia, with special reference to size dimorphism within the genus Pseudoboeckella
Read more of: Calanoid copepods from South Georgia, with special reference to size dimorphism within the genus PseudoboeckellaThree species of calanoid copepods, Boeckella michaelseni, Parabroteas sarsii and Pseudoboeckella poppei were recorded from 6 freshwater localities in the Husvik area, South Georgia. Of the latter species two distinct […]

Muscle fibre types and metabolism in post-larval and adult stages of notothenioid fish
Read more of: Muscle fibre types and metabolism in post-larval and adult stages of notothenioid fishA histochemical study was carried out on muscle fibre types in the myotomes of post-larval and adult stages of seven species of notothenioid fish. There was little interspecific variation in […]

Factors affecting weaning weight in Antarctic fur seals Arctocephalus gazella at South Georgia
Read more of: Factors affecting weaning weight in Antarctic fur seals Arctocephalus gazella at South GeorgiaRelationships between size, body condition, age and feeding-attendance patterns during pup rearing of female Antacrtic fur seals Arctocephalus gazella and their effects on the timing of birth and weaning, pup […]

The effects of freezing and desiccation on photosynthesis and survival of terrestrial Antarctic algae and cyanobacteria
Read more of: The effects of freezing and desiccation on photosynthesis and survival of terrestrial Antarctic algae and cyanobacteriaThe effects of low temperatures, freezing and desiccation on a cyanobacterium (Phormidium) and an alga (Prasiola) from terrestrial Antarctic habitats were investigated. Net photosynthesis per unit dry weight, measured by […]

Spatial and temporal distribution of Antarctic fur seals (Arctocephalus gazella) on the breeding grounds at Bird Island, South Georgia
Read more of: Spatial and temporal distribution of Antarctic fur seals (Arctocephalus gazella) on the breeding grounds at Bird Island, South GeorgiaThe number of Antarctic fur seals (Arctocephalus gazella) in the area of the Scotia Sea has been increasing. Observation of their distribution on the breeding grounds are important to help […]

Processes controlling the downstream evolution of ice rheology in glacier shear margins: case study on Rutford Ice Stream, West Antarctica
Read more of: Processes controlling the downstream evolution of ice rheology in glacier shear margins: case study on Rutford Ice Stream, West AntarcticaIce rheology governs how glaciers flow and respond to environmental change. The rheology of glacier ice evolves in response to a variety of mechanisms, including damage, heating, melting and the […]

Resolving the internal and basal geometry of ice masses using imaging phase-sensitive radar
Read more of: Resolving the internal and basal geometry of ice masses using imaging phase-sensitive radarThe phase-sensitive radio-echo sounder (pRES) is a powerful new instrument that can measure the depth of internal layers and the glacier bed to millimetre accuracy. We use a stationary 16-antenna […]

Critical Southern Ocean climate model biases traced to atmospheric model cloud errors
Read more of: Critical Southern Ocean climate model biases traced to atmospheric model cloud errorsThe Southern Ocean is a pivotal component of the global climate system yet it is poorly represented in climate models, with significant biases in upper-ocean temperatures, clouds and winds. Combining […]

Heavy metal and sulphur emissions to the atmosphere from human activities in Antarctica
Read more of: Heavy metal and sulphur emissions to the atmosphere from human activities in AntarcticaInvestigators have used the temporal record of heavy metal and sulphur concentrations in Antarctic snow to assess the extent of global atmospheric pollution in the Southern Hemisphere. These studies would […]
