The sub-AntarcticbeetleHydromedion sparsutum (Coleoptera, Perimylopidae) is common locally on the island of South Georgia where sub-zero temperatures can be experienced in any month of the year. Larvae were known to […]
Results from an intercomparison campaign of ultraviolet spectroradiometers that was organized at Nea Michaniona, Greece July, 1–13 1997, are presented. Nineteen instrument systems from 15 different countries took part and […]
The South Georgia region is characterised by high biomass and productivity of phytoplankton, zooplankton and vertebrate predators. Important commercial fisheries have been based at the island since the late 1700s, […]
Age composition is fundamental to understanding the population dynamics and productivity of a fish stock. The use of scales to estimate age can result in large errors in age data […]
The metabolism of 52–73-day old Antarcticfursealpups from Bird Island, South Georgia, was investigated during fasting periods of normal duration while their mothers were at sea foraging. Body mass decreased exponentially […]
An experiment involving the supplementary feeding of pups was conducted on Antarctic fur seals to investigate the factors influencing maternal foraging-attendance cycles and the differential use of nutritional resources for […]
Age, growth and populationstructure of the jumboflyingsquid, Dosidicusgigas, from the jig fishery in Peruvianwaters in 1992 were determined by reading daily increments in ground and polished sections of statoliths. The […]
Exploited populations of ommastrephidsquid are found under a wide range of oceanographic regimes. However, to date most scientific attention has focussed on those found in northern hemisphere western boundary current […]
The relationship between fitness and parental similarity has been dominated by studies of how inbreeding depression lowers fecundity in incestuous matings. A widespread implicit assumption is that adult fitness (reproduction) […]
The Ronne polynya formed in the Weddell Sea, Antarctica, during the period November 1997-February 1998 to an extent not seen previously in the 25 years of all-weather satellite observations. The […]
There are areas on Earth where it is pressing that we obtain an understanding of the thermal limits and acclimationcapacities of the species living there. These are the zones where […]
