3. Temperature and starvation effects on the metabolism of the brachiopod,Terebratulina retusa(L.)

   Oxygen consumption and ammonia excretion rates were assessed for Terebratulina retusa (L.) held under 3 different regimes of temperature and food availability. These were: 5.6ˆC, no food (cold, starved); 5.8ˆC, […]

4. Heavy metal pollution in Antarctica and its potential impacts on algae

   Antarctica is not free from environmental pollutants although it is often perceived as the last pristine continent on Earth. Research stations represent one of the largest forms of anthropogenic activity […]

5. Simulating the Last Interglacial Greenland stable water isotope peak: the role of Arctic sea ice changes

   Last Interglacial (LIG), stable water isotope values (δ18O) measured in Greenland deep ice cores are at least 2.5‰ higher compared to the present day. Previous isotopic climate simulations of the […]

6. Seasonal and ontogenetic changes in tissue size in the Antarctic brachiopod Liothyrella uva (Broderip, 1833)

   Tissue ash-free dry mass (AFDM) was investigated in relation to animal size (length) and season in Liothyrella uva (Broderip, 1833). Brachiopods were divided into digestive gland, gonads, lophophore, other internal […]

7. Scaling patterns in the Antarctic brachiopod Liothyrella uva (Broderip, 1833)

   Scaling patterns of shell thickness, shell volume, total animal volume, internal tissue volume and mantle cavity volume in the brachiopod Liothyrella uva (Broderip, 1833) were investigated in relation to shell […]

8. Temperature and basal metabolism in two Antarctic marine herbivores

   V̇o2 was measured for specimens of the Antarctic brachiopod Liothyrella uva and limpet Nacella concinna, using couloximetric techniques. Time-course studies revealed different responses to starvation by each species. N. concinna […]

11. Ontogeny of the lymphoid organs in an antarctic teleost, Harpagifer antarcticus (Notothenioidei: Perciformes)

    The effect of an evolutionary adaptation to low environmental temperature on the development of lymphoid organs was examined in Harpagifer antarcticus from Signy Island (South Orkney Islands; 60° 43′S, 45° […]

12. Depth-related changes in benthic diatom assemblages of a maritime Antarctic lake

    The epiphytic diatoms of filamentous matforming algae in Sombre Lake, Signy Island, South Orkneys, Antarctica were examined in a field study from January to March 1987. Results reveal 1) a […]
