Population dynamics of Magellania fragilis, a brachiopod dominating a mixed-bottom macrobenthic assemblage on the Antarctic shelf
Read more of: Population dynamics of Magellania fragilis, a brachiopod dominating a mixed-bottom macrobenthic assemblage on the Antarctic shelfA dense assemblage of the brachiopod Magellania fragilis was sampled by trawl and underwater photography during the expedition ANT IX/3 (1991) of RV ‘Polarstern’ on the shelf of the Lazarev […]

Validation of heart rate and doubly labelled water as measures of metabolic rate during swimming in California sea lions
Read more of: Validation of heart rate and doubly labelled water as measures of metabolic rate during swimming in California sea lions1. The measurement of energy expenditures in free-ranging animals is essential if we are to understand fully the interaction between a species and its environment. This study examined the validity […]

Swimming speed and allocation of time during the dive cycle in Antarctic fur seals
Read more of: Swimming speed and allocation of time during the dive cycle in Antarctic fur sealsDuring sustained bouts of diving, predators such as fur seals may adjust the time they spend diving to maximize the time they can spend foraging and minimize the time spent […]

Population Demography of Antarctic Fur Seals: The Costs of Reproduction and Implications for Life-Histories
Read more of: Population Demography of Antarctic Fur Seals: The Costs of Reproduction and Implications for Life-Histories1. This study examined the costs of reproduction in terms of future survival and reproduction in female Antarctic fur seals from Bird Island, South Georgia. It used mark-recapture data from […]

Modeling the formation and deposition of frazil ice beneath Filchner-Ronne Ice Shelf
Read more of: Modeling the formation and deposition of frazil ice beneath Filchner-Ronne Ice ShelfLarge areas of the Filchner-Ronne Ice Shelf are underlain by layers of marine ice, which form when supercooled seawater circulating beneath the ice shelf freezes. The freezing process initially produces […]

Drivers of interannual variability in virioplankton abundance at the coastal Western Antarctic Peninsula and the potential effects of climate change
Read more of: Drivers of interannual variability in virioplankton abundance at the coastal Western Antarctic Peninsula and the potential effects of climate changeAn eight year time-series in the Western Antarctic Peninsula (WAP) with an approximately weekly sampling frequency was used to elucidate changes in virioplankton abundance and their drivers in this climatically-sensitive […]

Global patterns of sex- and age-specific variation in seabird bycatch
Read more of: Global patterns of sex- and age-specific variation in seabird bycatchFisheries bycatch is a major threat to seabird populations, and understanding sex- and age-biases in bycatch rates is important for assessing population-level impacts. We analysed 44 studies to provide the […]
