Background The Ice krill, Euphausia crystallorophias is one of the species at the base of the Southern Ocean food chain. Given their significant contribution to the biomass of the Southern […]
The West Antarctic Peninsula (WAP) is home to large breeding colonies of the ice-dependent Antarctic Adélie penguin (Pygoscelis adeliae). Although the entire inner continental shelf is highly productive, with abundant […]
The extent, duration, and seasonality of sea ice and glacial discharge strongly influence Antarctic marine ecosystems. Most organisms’ life cycles in this region are attuned to ice seasonality. The annual […]
Antarctic krill is a cold water species, an increasingly important fishery resource and a major prey item for many fish, birds and mammals in the Southern Ocean. The fishery and […]
The Weddell Sea sector is one of the main formation sites for Antarctic Bottom Water and an outlet for about one fifth of Antarctica’s continental ice volume. Over the last […]
In the Maritime Antarctic and High Arctic, soil microhabitat temperatures throughout the year typically range between -10 and +5°C. However, on occasion, they can exceed 20°C, and these instances are […]
This study examined three competing hypotheses to explain how lactating Antarctic fur seals (Arctocephalus gazella) respond to changes in the level of resource availability. Antarctic fur seals have episodic bouts […]
The nitrogenous excretion rates (total ammonia nitrogen, urea, and primary amines) of plunderfish Harpagifer antarcticus were related significantly to length and to wet mass (mass exponents of 0·94, 1·01, 1·07 […]
Rhynchonellid brachiopods are reported for the first time from the Oberek Cliff Member of the Oligocene Polonez Cove Formation of King George Island, South Shetland Islands, West Antarctica. Rhynchonellids are […]
The influence of two sampling protocols on diet determination of two marine predators, the gentoo penguin (Pygoscelis papua) and Antarctic fur seal (Arctocephalus gazella), was investigated. The collection of diet […]
