1. Effects of physical factors on photosynthesis by the Antarctic liverwort Marchantia berteroana

   Effects of irradiance, temperature and water availability on respiration and photosynthesis in a maritime Antarctic liverwort, Marchantia berteroana, were investigated. Carbon dioxide exchange was measured using an infra-red gas analysis […]

2. Effects of continuous and repeated dehydration on carbon fixation by bryophytes from the maritime Antarctic

   The effects of dehydration and rehydration on carbon exchange in 14 bryophytes from the maritime Antarctic were investigated using an infra-red gas analysis system. Continuous long-term (1–12 months) and repeated […]

3. Comparisons of the biology of the intertidal Subantarctic limpets Nacella concinna and Kerguelenella lateralis

   Two limpet species occur intertidally on subantarctic South Georgia, the patellid Nacella concinna and the siphonarlid Kerguelenella lateralis. N. concinna is confined to the lower shore close to LWS; K. […]

4. Gondwanian age dextral transpression and spatial kinematic partitioning within the Heritage Range, Ellsworth Mountains, West Antarctica

   The Ellsworth Mountains, West Antarctica, consist of two mountain ranges; the Sentinel, and Heritage ranges. The more southerly Heritage Range is composed of a lower Paleozoic sedimentary and volcanic rock […]

5. Measurements of calcium and phosphorus concentrations in the neonatal dentine of Weddell and crabeater seals using energy-dispersive x-ray analysis

   Concentrations of calcium and phosphorus were measured in the neonatal dentine of 11 crabeater and 11 Weddell seal postcanine teeth with an energy-dispersive x-ray analyser. The extent of variation in […]

6. Dietary segregation of krill-eating South Georgia seabirds

   The diets of six of the main seabird species (two petrels, two albatrosses, two penguins) breeding at Bird Island, South Georgia were studied simultaneously during the chick-rearing period in 1986. […]

8. Rapid procedure for the isolation and analysis of fatty acid and fatty alcohol fractions from wax esters of marine zooplankton

   A rapid and simple method for the isolation of fatty acid methyl esters and fatty alcohols from the lipid fraction of marine zooplankton is described. Wax esters are the dominant […]

9. The fate in the marine environment of a minor diesel fuel spill from an Antarctic Research Station

   Monitoring was undertaken of the fate in the marine environment of an accidental spill of diesel fuel (1000 litres) from Faraday Research Station, Galindez Island, Antarctica in March 1992. On […]

10. The last inoceramid bivalves in Antarctica

    The last inoceramid bivalves in Antarctica are no younger than mid- to late Campanian in age. They occur within the Herbert Sound and Rabot Point members of the Santa Marta […]

12. An evolutionary framework for the polar regions

    Abstract: Our knowledge of the nature, generation and maintenance of largescale biodiversity patterns is still far from complete. This is particularly so in the Southern Hemisphere and in the marine […]
