David Grémillet, Auteur ; Aurore Ponchon, Auteur ; Michelle Paleczny, Auteur ; Maria-Lourdes D. Palomares, Auteur ; Vasiliki Karpouzi, Auteur ; Daniel Pauly, AuteurFisheries transform marine ecosystems and compete with predators [ 1 ], but temporal trends in seabird-fishery competition had never been assessed on a worldwide scale. Using catch reconstructions [ 2 ] for all fisheries targeting taxa that ar[...]![]()

Craig R. White, Auteur ; David Boertmann, Auteur ; David Grémillet, Auteur ; Patrick J. Butler, Auteur ; Jonathan A. Green, Auteur ; Graham R. Martin, AuteurArctic seas have warmed and sea ice has retreated. This has resulted in range contraction and population declines in some species, but it could potentially be a boon for others. Great Cormorants Phalacrocorax carbo have a partially wettable plum[...]![]()

David Grémillet, Auteur ; Clara Peron, Auteur ; Pascal Provost, Auteur ; Amelie Lescroel, AuteurForeign fisheries massively harvest waters off West Africa, plundering local marine economies and threatening African food security. Here we warn that these fisheries might affect both juvenile and adult European seabirds during their autumn mig[...]![]()

Behavioural strategies of cormorants (Phalacrocoracidae) foraging under challenging light conditions
Craig R. White, Auteur ; Patrick J. Butler, Auteur ; David Grémillet, Auteur ; Graham R. Martin, AuteurDans Ibis (150 AUG 2008)Diving is indicative of foraging in cormorants (Phalacrocoracidae). We have investigated a range of parameters associated with diving in Great Cormorants Phalacrocorax carbo to provide insight into the bases of cormorant predatory strategies. We[...]![]()

Emilie Tew-Kai, Auteur ; Simon Benhamou, Auteur ; Carl D. van der Lingen, Auteur ; Janet C. Coetzee, Auteur ; Lorien Pichegru, Auteur ; Peter G. Ryan, Auteur ; David Grémillet, AuteurClimate change and fishing impact marine ecosystems, potentially modifying the availability of small pelagic fish to marine top predators. Some seabirds that primarily rely upon these resources have switched to feeding on fishery waste. It has t[...]![]()

Nicola C. Okes, Auteur ; Philip A. R. Hockey, Auteur ; Lorien Pichegru, Auteur ; Carl D. van der Lingen, Auteur ; Robert J. M. Crawford, Auteur ; David Grémillet, AuteurIn the southern Benguela upwelling ecosystem off the west coast of South Africa, seabird populations are decreasing dramatically because of reduced availability of pelagic fish. We tested the hypothesis that the west coast fishing industry is co[...]![]()

Energetic consequences of contrasting winter migratory strategies in a sympatric Arctic seabird duet
Jérôme Fort, Auteur ; Harald Steen, Auteur ; Hallvard Strom, Auteur ; Yann Tremblay, Auteur ; Eirik Gronningsaeter, Auteur ; Emeline Pettex, Auteur ; Warren P. Porter, Auteur ; David Grémillet, AuteurAt the onset of winter, warm-blooded animals inhabiting seasonal environments may remain resident and face poorer climatic conditions, or migrate towards more favourable habitats. While the origins and evolution of migratory choices have been ex[...]![]()

Manfred R. Enstipp, Auteur ; David R. Jones, Auteur ; Svein-Hakon Lorentsen, Auteur ; David Grémillet, AuteurCormorants and shags are foot propelled pursuit divers that forage on benthic and pelagic fish. Previous studies suggested that diving in cormorants is extremely costly, and this is usually attributed to their partially wettable plumage and inef[...]![]()
