I am professor of behavioural ecology in the university of Lyon. My research interests lie in the fields of animal behaviour, decision-making, rationality, mate choice, sexual selection, animal personality, and foraging strategy. So far, I had the opportunity to work on a wide range of species: insects (honeybee, ants, carabids, Tenebrio), amphipod (Gammarux pulex), fish (convict cichlid, round goby), and bird (Zenaida dove). In addition to this experimental work, I indulge myself in theoretical approaches. From a taxonomic viewpoint, my favourite species of models are related to game theory, dynamical systems, and individual based simulations. Finally, I am also interested in statistical methodology.

Touchy matter: the delicate balance between Morgan’s canon and open-minded description of advanced cognitive skills in the animal

In a recent paper published in PNAS, Fayet et al. [1] reported scarce field observations of two Atlantic puffins (four years apart) apparently scratching their bodies using sticks, which was interpreted by the authors as evidence of tool use in this species. In a short response, Benjamin Farrar [2] raises serious concerns about this interpretation and proposes simpler, more parsimonious, mechanisms explaining the observed behaviour: a textbook case of Morgan's canon.
In virtually all introd...

Optimal foraging in a changing world: old questions, new perspectives

Marginal value theorem (MVT) is an archetypal model discussed in every behavioural ecology textbook. Its popularity is largely explained but the fact that it is possible to solve it graphically (at least in its simplest form) with the minimal amount of equations, which is a sensible strategy for an introductory course in behavioural ecology [1]. Apart from this heuristic value, one may be tempted to disregard it as a naive toy model. After a burst of interest in the 70's and the 80's, the once v...
