  1. Mackerel icefish size and age at South Georgia and Shag Rocks

    Abstract:  Mackerel icefish, Champsocephalus gunnari (Lönnberg), at South Georgia and Shag Rocks in the Southern Ocean have supported a fishery since the 1970s. This study has analysed the length-frequency distribution of C. gunnari from 10 bottom trawl surveys at South Georgia and 9 at Shag Rocks

  2. Population dynamics of the wandering albatross Diomedea exulans at Marion Island: long-line fishing and environmental influences

    Abstract:  The subantarctic Prince Edward Islands (Marion and Prince Edward) support the largest breeding population of the Vulnerable wandering albatross Diomedea exulans. The numbers of birds breeding in the Marion Island population has fluctuated over the past three decades and appears to be the

  3. The oldest known banded wandering albatross Diomedea exulans at the Prince Edward Islands

    Abstract:  The oldest known wandering albatross Diomedea exulans at the Prince Edward Islands is estimated to have been approximately half a century old when last recaptured in 2001. Demographic studies need to continue for several more decades before the true maximum longevity of the species

  4. Unusual breeding by seabirds at Marion Island during 1997/98

    Abstract:  In 1997/98, breeding at subantarctic Marion Island was exceptionally good for five species of seabirds capable of foraging over wide areas and for a tern. The number of king penguin Aptenodytes patagonicus chicks surviving to the start of spring in 1997 was considerably more than

  5. Conserving surface-nesting seabirds at the Prince Edward Islands: the roles of research, monitoring and legislation

    Abstract:  South Africa’s subantarctic Prince Edward Islands support substantial proportions of the global populations of a number of surface-nesting seabirds. Populations of most of these have decreased at the islands since the 1980s and 12 of 16 species are regarded as Threatened or Near

  6. Population and breeding of the gentoo penguin Pygoscelis papua at Marion Island, 1994/95 to 2002/03

    Abstract:  The numbers of gentoo penguins Pygoscelis papua breeding at subantarctic Marion Island fell by 40%, from 1994/95 to 2002/03 from 1 352 pairs to 806 pairs. Apart from a slight increase in 1998/99, there was a steady decrease in numbers breeding between 1995/96 and 2000/01, when the

  7. Ecological games in space and time: the distribution and abundance of Antarctic krill and penguins

    Abstract:  The distribution and abundance of organisms are affected by behaviors, such as habitat selection, foraging, and reproduction. These behaviors are driven by interactions within and between species, environmental conditions, and the biology of the species involved. Although extensive

  8. An ecosystem-based approach to management: using individual behaviour to predict the indirect effects of Antarctic krill fisheries on penguin foraging

    Abstract:  1. Changes in species’ abundance and distributions caused by human disturbances can have indirect effects on other species in a community. Although ecosystem approaches to management are becoming increasingly prevalent, they require a fuller understanding of how individual behaviour

  9. Mackerel icefish ecological indices

    Abstract:  Mackerel icefish have been harvested in the CCAMLR Region for over thirty years. In the Atlantic sector of the Southern Ocean they feed preferentially on krill and are themselves preyed upon by fur seals and several avian species. These attributes make them suitable for consideration

  10. Adélie penguin foraging behaviour and breeding success in seasons of contrasting krill availability (Mawson Coast, Antarctica)

    Abstract:  Parameters measured under the CCAMLR Ecosystem Monitoring Program (CEMP) for Adélie penguins at the Béchervaise Island CEMP site were compared between seasons of contrasting krill availability. Krill biomass estimates were derived from shipboard surveys carried out within the penguins’
