research interests Version imprimable
I am a behavioural ecologist. More specifically, my research interests lie in the fields of animal behaviour, decision rules, 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), 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.

video: coordinated nest defense in the convict cichlid Version imprimable

Image

Cordinated nest defense against fry predators by a pair of Convict cichlid (Amatitlania siquia), a monogamous tropical fish species. The video was recorded in Lake Xiloà, Nicaragua. In natural environment, the eggs and young are highly vulnerable to predation from other fish species or even convict cichlids (cannibalism). Both parents perform intensive coordinated defense of the nest entrance in order to repel intruders sometimes much larger than themselves.

video: double amplexus in Gammarus pulex Version imprimable

Image

In Gammarus pulex, the pair formation is characterized by a long-lasting mate guarding behaviour, named amplexus, in which a male grasps a female for up to 20 days until the sexual receptiviy of the female. In this video recorded in laboratory conditions, a male is attempting to handle two females, possibly in order to compare the two mating options.
