Aim: To provide a method of analyzing penguin tracking data to identify priority at-sea areas for seabird conservation (marine IBAs), based on pre-existing approaches for flying seabirds but revised according […]
The mechanisms that determine patterns of species dispersal are important factors in the production and maintenance of biodiversity. Understanding these mechanisms helps to forecast the responses of species to environmental […]
Understanding the physiology of non-native species in Antarctica is key to elucidating their ability to colonise an area, and how they may respond to changes in climate. Eretmoptera murphyi is […]
Recruitment of Wandering Albatrosses Diomedea exulans to the breeding population at South Georgia took between 2 and 8 years after they first returned to their natal colony. In successive seasons, […]
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, […]
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 […]
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 […]
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 […]
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 […]
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 […]
