Long-Term Changes in Seabird and Seal Populations in the Southern Ocean

  • P. Jouventin
  • H. Weimerskirch


This chapter reports on trends in the breeding populations of selected species at Dumont D’Urville, Antarctica and at Crozet, Amsterdam and Kerguelen Islands (French Austral and Antarctic territories). Populations of 12 seabird and three seal species are reviewed and analyzed. While most of the penguin and fur seal populations are today increasing, several populations of albatrosses and petrels and elephant seals are dangerously declining. Most of the changes reported here are considered to have been induced by past and present human activities. The importance of monitoring and demographic studies of birds and seals for managing and protecting the living resources of the Southern Ocean is stressed.
