During 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 […]
1. 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 […]
Large 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 […]
The water status of the collembolan Cryptopygtus antarcticus (Willem) was investigated from April 1984 to December 1987 at Signy Island, maritime Antarctic, by monthly field sampling to determine body water […]
This paper is dedicated to the late Nigel Bonner, who as Head of the Life Sciences Division at British Antarctic Survey, encouraged and supported this research with his characteristic enthusiasm. […]
An 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 […]
Fisheries 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 […]
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 […]
