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 […]

Heart rate and oxygen consumption of exercising gentoo penguins
Read more of: Heart rate and oxygen consumption of exercising gentoo penguinsHeart 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 […]

The energy expenditure of free-ranging black-browed albatrosses
Read more of: The energy expenditure of free-ranging black-browed albatrossesAs 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$_{text{ab}}$) […]

Antarctic pack-ice seal research, February and March 1995
Read more of: Antarctic pack-ice seal research, February and March 1995As 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 […]

Seasonal abundance and size variation in Antarctic populations of the Cladoceran Daphniopsis studeri
Read more of: Seasonal abundance and size variation in Antarctic populations of the Cladoceran Daphniopsis studeriContinental 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 […]

Seasonality of feeding activity in Antarctic suspension feeders
Read more of: Seasonality of feeding activity in Antarctic suspension feedersThe 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. […]

Epibiotic communities on sublittoral macroinvertebrates at Signy Island, Antarctica
Read more of: Epibiotic communities on sublittoral macroinvertebrates at Signy Island, AntarcticaThe 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, […]
