The Antarctic Peninsula is experiencing one of the fastest rates of regional climate change
on Earth, resulting in the collapse of ice shelves, the retreat of glaciers and the exposure of …

The Scotia Sea ecosystem is a major component of the circumpolar Southern Ocean system,
where productivity and predator demand for prey are high. The eastward-flowing Antarctic …

Determining the form of key predator-prey relationships is critical for understanding marine
ecosystem dynamics. Using a comprehensive global database, we quantified the effect of …

To understand how planet Earth works we study it increasingly as a system–a collection of
interdependent parts or spheres–the lithosphere, the hydrosphere, the cryosphere, the …

We aim to identify the important steps in the evolution of the ecosystem approach to
management under the Convention on the Conservation of Antarctic Marine Living …

We review the application of multispecies models as tools for evaluating impacts of fishing
on marine communities. Four types of model are identified: descriptive multispecies …

The South Georgia region is characterised by high biomass and productivity of
phytoplankton, zooplankton and vertebrate predators. Important commercial fisheries have …

The mechanisms by which variability in sea ice cover and its effects on the demography of
the Antarctic krill Euphausia superba cascade to other ecosystem components such as apex …

Intrusion of Upper Circumpolar Deep Water (UCDW), which was derived from the Antarctic
Circumpolar Current (ACC), onto the western Antarctic Peninsula (WAP) shelf region in …

Antarctic krill, Euphausia superba, has been studied since the early 1920s including
distribution, life cycle and behavioural biology. Quantitative aspects of distribution, biomass …
