     Director of Research






Director of the program 1091 « Adélie penguins as bio-platforms of the marine environment » from the French polar Institute IPEV, co-director of the Zone Atelier Antarctique, Secretary of the Expert Group on Birds and Marine Mammals and the Life Science group of the Scientific Committee on Antarctic Research, Representing the CNRS at the Protected Areas Commission of the CNPN, Member of the multidisciplinary Commission 54 of the CNRS national committee. Academic editor at Plos One, Movement Ecology, Marine Ornithology, Conservation Physiology.




I study the capacity of top predators to face environmental changes, especially changes in resources availability. Here, top predators are used as eco-indicating species of the environmental changes. To this end, I am involved in the creation and maintenance of long-term monitoring systems that examine the foraging – including prey-predator interactions – and reproducing activities of key predator species in various marine ecosystems, in Australia (little penguins, collaboration with A Chiaradia), in Antarctica (Adélie penguin, through my polar program 1091 l’AMMER, with the support of IPEV and WWF), in the Arctic (guillemots, collaboration with K. ELLIOT in Canada and S. DESCAMPS in Norway), in the subantarctic territories of South Africa (Marion Island, various species of seabirds, collaboration with P.G. RYAN). This monitoring activity tallies with my involvement in the Expert Group on Birds and Marine Mammals (EG-BAMM) of the Scientific Committee for Antarctic Research. Through EG-BAMM I indeed participate to the elaboration of the Biogeographic Atlas of the Southern Ocean of the Census of Antarctic Marine Life and the Retrospective Analysis of Antarctic Tracking Data for all the marine top predators of the Southern Ocean (Raymond et al. 2014 Ecography). These studies aim at defining the Areas of Ecological Significance for the marine predators so as to submit them for consideration to the Marine Protected Areas.


I complement the aforementioned ecosystemic approach with the study of the ecophysiological and behavioural strategies that individuals use so as to understand why some individuals are better than others in foraging or reproductive tasks.





In the frame of studies, I am a strong advocate of Bio-logging, in which animals are instrumented with miniature data-recording devices that monitor the biological data of the animals and/or the physical data of its immediate surroundings (cf. ROPERT-COUDERT & WILSON 2005, ROPERT-COUDERT et al. 2012 INEE’s White Book).






In this context I recently organized the 5th International Bio-logging Science Symposium in Strasbourg in 2014. In parallel, I develop with AJJ MacIntosh a novel analytical approach to examine the behavioural organization of free-ranging individuals through the use of fractal analysis. We are particularly interested in examining how the complexity of the behaviour changes with the emergence of constraints in the environment or with changes in the health of the individual.
