Heart rate () and oxygen consumption () were recorded from gentoo penguins walking on a variable-speed treadmill. After an initial increase, and increased linearly with walking speed. A curvilinear regression […]
As heart rate (f$_{text{H}}$) can be used to determine the energy expenditure of black-browed albatrosses (Diomedea melanophrys) (Bevan et al. 1994), data loggers – recording f$_{text{H}}$ and abdominal temperature (T$_{text{ab}}$) […]
As upper trophic level predators with a circumpolar distribution, the antarctic pack ice seals (crabeater, Lobodon carcinophagus; leopard, Hydrurga leptonyx; Ross, Ommatophoca rossii; and Weddell, Leptonychotes weddelli) provide a potential […]
Continental freshwater lakes of Antarctica are characterized by species-poor biota (Heywood 1977). The plankton is dominated by algae, bacteria and protozoa (Koob & Leister 1972, Parker et al. 1982, Laybourn-Parry […]
The feeding activity of four benthic suspension-feeding groups (bryozoans, hydroids, polychaetes and holothurians) was monitored in situ every month for a 2-year period at Signy Island in the maritime Antarctic. […]
The epibiotic communities on locally abundant macroinvertebrates, in particular the brachiopod Liothyrella uva and the limpet Nacella concinna, were examined from depths between 0 and 50 m at Signy Island, […]
Photographic samples were taken every 5 m along two 40 m transects on mostly rock face at Signy Island, Antarctica, during the austral winter of 1991. Dense and taxonomically rich […]
Photographs were taken every 0.5 m along three transects of 5.5 m length on shallow rock faces at Signy Island, Antarctica, during the austral summer of 1991/1992. The percentage cover […]
Seasonal and annual growth was monitored in situ at Signy Island in two species of bryozoan of different growth morphologies, using photographic and tagging techniques. Cellarinella watersi, a heavily calcified […]
This chapter reviews the tectonic evolution of the East Scotia Sea, testing and extending previously published conclusions in light of the additional and expanded data sets now available. The East […]
Polar ice caps preserve information about atmospheric composition over the past tens of thousands to hundreds of thousands of years. They contain a rich history of the Earth’s volcanic activity, […]
