David Grémillet, Auteur ; Marion Vittecoq, Auteur ; Thierry Boulinier, AuteurVisibles de tous, les oiseaux nous renseignent sur l’état de leurs milieux de vie. Ils y sont exposés aux pollutions plastiques et chimiques, aux agents pathogènes, aux conséquences des changements climatiques et à la surexploitation des ressour[...]Article
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[...]Article
Flavio Monti, Auteur ; David Grémillet, Auteur ; Andrea Sforzi, Auteur ; Giampiero Sammuri, Auteur ; Jean Marie Dominici, Auteur ; Rafel Triay Bagur, Auteur ; Antoni Muñoz Navarro, Auteur ; Leonida Fusani, Auteur ; Olivier Duriez, AuteurA broad range of migration strategies exist in avian species, and different strategies can occur in different populations of the same species. For the breeding Osprey Pandion haliaetus populations of the Mediterranean, sporadic observations of r[...]Article
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[...]Article
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[...]Article
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[...]Article
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[...]Article
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[...]Article
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[...]Article
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[...]Article
Clara Peron, Auteur ; David Grémillet, Auteur ; Aurelien Prudor, Auteur ; Emeline Pettex, Auteur ; Claire Saraux, Auteur ; Andrea Soriano-Redondo, Auteur ; Matthieu Authier, Auteur ; Jérôme Fort, AuteurMarine Protected Areas (MPAs) are being established across all marine regions but their validity for the conservation of highly mobile marine vertebrates has been questioned. We tested the hypothesis that French coastal MPAs primarily designed f[...]Article
Morten Frederiksen, Auteur ; Sebastien Descamps, Auteur ; Kjell Einar Erikstad, Auteur ; Anthony J. Gaston, Auteur ; H. Grant Gilchrist, Auteur ; David Grémillet, Auteur ; Kasper L. Johansen, Auteur ; Yann Kolbeinsson, Auteur ; Jannie F. Linnebjerg, Auteur ; Mark L. Mallory, Auteur ; Laura A. McFarlane Tranquilla, Auteur ; Flemming R. Merkel, Auteur ; William A. Montevecchi, Auteur ; Anders Mosbech, Auteur ; Tone K. Reiertsen, Auteur ; Gregory J. Robertson, Auteur ; Harald Steen, Auteur ; Hallvard Strom, Auteur ; Thorkell L. Thorarinsson, AuteurPelagic seabirds are exposed to an array of potential threats during the non-breeding period, and effective management of these threats on a large scale requires knowledge of which populations winter where. Thick-billed murres (Uria lomvia) are [...]Article
Svein-Hakon Lorentsen, Auteur ; Kjersti Sjotun, Auteur ; David Grémillet, AuteurCoastal kelp forest ecosystems provide important habitats for a diverse assemblage of invertebrates, fish and marine top-predators such as seabirds and sea mammals. Although kelp is harvested industrially on a worldwide scale little is known abo[...]Article
W. James Grecian, Auteur ; Matthew J. Witt, Auteur ; Martin J. Attrill, Auteur ; Stuart Bearhop, Auteur ; Brendan J. Godley, Auteur ; David Grémillet, Auteur ; Keith C. Hamer, Auteur ; Stephen C. Votier, AuteurSeabirds are well monitored and protected at their breeding grounds but spend most of their life at sea, where they are less well monitored and afforded little protection. In an attempt to address this dichotomy, attention has been directed towa[...]Article
Celine Le Bohec, Auteur ; Michel Gauthier-Clerc, Auteur ; David Grémillet, Auteur ; Roger Pradel, Auteur ; Arnaud Béchet, Auteur ; Jean-Paul Gendner, Auteur ; Yvon Le Maho, Auteur1. Understanding the trade-off between current reproductive effort, future survival and future breeding attempts is crucial for demographic analyses and life history studies. 2. We investigated this trade-off in a population of king penguins (Ap[...]Article
Chris B. Thaxter, Auteur ; Francis Daunt, Auteur ; Keith C. Hamer, Auteur ; Yutaka Watanuki, Auteur ; Mike P. Harris, Auteur ; David Grémillet, Auteur ; Gerrit Peters, Auteur ; Sarah Wanless, AuteurSexual differences in food provisioning rates of monomorphic seabirds are well known but poorly understood. Here, we address three hypotheses that attempt to explain female-biased food provisioning in common guillemots Uria aalge: (1) males spen[...]Article
Yan Ropert-Coudert, Auteur ; Francis Daunt, Auteur ; Akiko Kato, Auteur ; Peter G. Ryan, Auteur ; Sue Lewis, Auteur ; Kaori Kobayashi, Auteur ; Yoshihisa Mori, Auteur ; David Grémillet, Auteur ; Sarah Wanless, AuteurPlunge-diving is a specialised hunting tactic used by some avian predators to overcome the high buoyancy encountered near the water surface and surprise prey. However, plunge-diving is effective only to a certain depth; to access deeper prey, bi[...]
