Extremum statistics: a framework for data analysis
Recent work has suggested that in highly correlated systems, such as sandpiles, turbulent fluids, ignited trees in forest fires and magnetization in a ferromagnet close to a critical point, the […]

Cretaceous patterns of floristic change in the Antarctic Peninsula
Read more of: Cretaceous patterns of floristic change in the Antarctic PeninsulaCretaceous radiation of angiosperms from low to high palaeolatitudes, coupled with the break-up of Gondwana, played a major role in establishing and maintaining biogeographic patterns across the southern hemisphere. Uncertainties […]

Silicic volcanism: an undervalued component of large igneous provinces and volcanic rifted margins
Read more of: Silicic volcanism: an undervalued component of large igneous provinces and volcanic rifted marginsSilicic volcanic rocks are associated with most, if not all, continental flood basalt provinces and volcanic rifted margins, where they can form substantial parts of the eruptive stratigraphy and have […]

Integrated environment-prey-predator interactions off South Georgia: implications for management of fisheries
Read more of: Integrated environment-prey-predator interactions off South Georgia: implications for management of fisheries1. The oceanography of the South Georgia region is principally that of the Southern Ocean rather than the South Atlantic. A combination of factors, including advection, local bathymetry and high […]

Estimating food consumption of marine predators: Antarctic fur seals and macaroni penguins
Read more of: Estimating food consumption of marine predators: Antarctic fur seals and macaroni penguins1. Estimating food consumption is central to defining the ecological role of marine predators. This study developed an algorithm for synthesizing information about physiology, metabolism, growth, diet, life history and […]

The energetics of gentoo penguins, Pygoscelis papua, during the breeding season
Read more of: The energetics of gentoo penguins, Pygoscelis papua, during the breeding season1. The food consumption of an animal. both at the individual and the population level, is an essential component for assessing the impact of that animal on its ecosystem. As […]

Feather mercury levels in seabirds at South Georgia: influence of trophic position, sex and age
Read more of: Feather mercury levels in seabirds at South Georgia: influence of trophic position, sex and ageWe studied the mercury contamination of 13 species of seabirds breeding on Bird Island, South Georgia, in 1998. Total mercury concentrations in body feather samples of birds caught at their […]
