1. OCEANIC CIRCUMPOLAR HABITATS OF ANTARCTIC KRILL

   Abstract:  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 current view that krill require high food concentrations, with a distribution often linked to shelves. For a

2. LIFE HISTORY BUFFERING IN ANTARCTIC MAMMALS AND BIRDS AGAINST CHANGING PATTERNS OF CLIMATE AND ENVIRONMENTAL VARIATION

   Abstract:  The consequences of warming for Antarctic long-lived organisms depend on their ability to survive changing patterns of climate and environmental variation. Among birds and mammals of different Antarctic regions, including emperor penguins, snow petrels, southern fulmars, Antarctic fur

3. ENVIRONMENTAL FORCING AND SOUTHERN OCEAN MARINE PREDATOR POPULATIONS: EFFECTS OF CLIMATE CHANGE AND VARIABILITY

   Abstract:  The Southern Ocean is a major component within the global ocean and climate system and potentially the location where the most rapid climate change is most likely to happen, particularly in the high-latitude polar regions. In these regions, even small temperature changes can potentially

4. ECOLOGICAL REPERCUSSIONS OF HISTORICAL FISH EXTRACTION FROM THE SOUTHERN OCEAN

   Abstract:  A major mid-1980s shift in ecological structure of significant portions of the Southern Ocean was partially due to the serial depletion of fish by intensive industrial fishing, rather than solely to climate factors as previously hypothesised. Over a brief period (1969-1973), several

5. Histopathology of Antarctic krill, Euphausia superba, bearing black spots

   Abstract:  Small black spots have been noticed on the cephalothorax of Antarctic krill, Euphausia superba, since January, 2001. To study the nature of the black spots, the krill were sampled in the winter of 2003, 2006, and 2007 in the South Georgia region, the Antarctic Ocean. Histological

6. Horizontal and vertical distribution and demography of euphausiids in the Ross Sea and its adjacent waters in 2004/2005

   Abstract:  The horizontal and vertical distribution and population structure of euphausiids in the Ross Sea and its adjacent waters were investigated during the summers of 2004/2005 using stratified towed samples. Nine species of euphausiids occurred in the survey area. Among them, Euphausia

7. THE POWER OF ECOSYSTEM MONITORING

   Abstract:  1. Implementing an ecosystem approach to fisheries management requires an effective ecosystem monitoring programme, the utility of which depends upon its ability (measured by the statistical power) to detect effects that trigger management action. 2. Using data from a long-term ecosystem

8. INTERANNUAL SPATIAL VARIABILITY OF KRILL (EUPHAUSIA SUPERBA) INFLUENCES SEABIRD FORAGING BEHAVIOR NEAR ELEPHANT ISLAND, ANTARCTICA

   Abstract:  We investigate the influence of krill (principally Euphausia superba) patchiness on the foraging distributions of seabirds to understand how variation in krill influences patch dynamics between krill and birds. At sea surveys were conducted near Elephant Island, Antarctica for three
