This Atlas of top predators from the French Southern Territories in the Southern Indian Ocean is asummary of information on the use of the southern Indian Ocean by 22 seabirds and seals species:king penguin, gentoo penguin, Adelie penguin, eastern rockhopper penguin, northern rockhopperpenguin, macaroni penguin, Amsterdam albatross, wandering albatross, black-browed albatross,Indian yellow-nosed albatross, light-mantled albatross, sooty albatross, southern giant petrel,northern giant petrel, southern fulmar, Cape petrel, snow petrel, white-chinned petrel, grey petrel,brown skua, southern elephant seal and Antarctic fur seal.The distribution map of each species was obtained by the use of tracking methods that allowidentifying important areas in the southern Indian Ocean. The determination of zones of high speciesrichness suggests several important areas for top predators. First the breeding colonies andsurrounding zones: Amsterdam and Saint Paul Islands, Marion and Prince Edward islands and the DelCano Rise, Crozet Islands, Kerguelen Plateau and East Antarctica (Adlie Land sector). Second, theupwelling-current zones: Benguela and Agulhas Currents Systems and third several the oceanic zones:the Southwest Indian Ridge (East Bouvetya and the North Subtropical Front), the Mid-Indian Ridge(North of Kerguelen and the Eastern Indian Ocean, the Southeast Indian Ridge (Great Australian Bightand Tasmania, Ob and Lena Banks, and East Antarctica (Prydz Bay - Queen Maud Land sectors, AdlieLand sector).The analysis of distribution indicates that some pelagic species have a much wider foraging rangeoutside the breeding season than during the breeding season (some disperse over very large areas,i.e. wandering albatross). This highlights the urgent need to strengthen collaborations, namelybetween conservation and management organisms such as CCAMLR and the fisheries organisations(RFMOs), to ensure the protection of these species and the conservation of the ecosystem that willalso be beneficial for many other species.In ...
