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

Southern Ocean biodiversity reflects past climate, oceanographic, and tectonic changes.
Molecular data from contemporary populations carry signatures of these processes. Here …

Antarctic krill Euphausia superba (hereafter 'krill') occur in regions undergoing rapid
environmental change, particularly loss of winter sea ice. During recent years, harvesting of …

Surveys of Euphausia superba often target localised shelves and ice edges where their
growth rates and predation losses are atypically high. Emphasis on these areas has led to …

The isolation of the Southern Ocean after the opening of Drake Passage some 23–25 million
years ago, the formation of the Antarctic Circumpolar Current, the subsequent cooling of the …

Rafting of marine and terrestrial organisms has important ecological, biogeographical and
evolutionary implications. Herein the general principles of rafting are described and how …

In January and February 2000, a collaborative survey designed to assess the biomass of
Antarctic krill across the Scotia Sea was conducted aboard research vessels from Japan …

Open‐ocean environments provide few obvious barriers to the dispersal of marine
organisms. Major currents and/or environmental gradients potentially impede gene flow …

The Antarctic biota is highly endemic, and the diversity and abundance of taxonomic groups
differ from elsewhere in the world. Such characteristics have resulted from evolution in …

The environmental and/or life history factors affecting genetic exchange in marine species
with potential for high dispersal are of great interest, not only from an evolutionary standpoint …
