My interests lie in the study of behaviour and life history evolution via an empirical approach, and I take a particular joy in testing theoretical predictions via experiments and statistics. I am also Associate Professor at the University of Amiens (France) but currently enjoying a leave of absence to study the joint evolution of extra-pair mating and cooperation in socially monogamous species.

 

Promiscuity and cooperation in socially monogamous species

I am currently testing recent models from Christian Joergensen and Sigrunn Eliassen on the evolution of female promiscuity and cooperation in socially monogamous species (Click here).

Using longitudinal data combined with field experiments, I am investigating the main predictions from the model, which shows that extra-pair mating creates incentives for males to cooperate more within neighbourhoods, because their potential reproductive success is spread out among several nests (click here for a nice Nature News & Views on the topic!).

Evolution of parasite life histories

I am also interested in life history evolution, with a particular focus on parasite life histories.

Because they have a very tight relationship with the hosts on which they rely, parasites often experience strong selection, and hence may display rapid adaptive changes in their life-history traits. I am currently studying how the conditions prevailing in salmon aquaculture may have selected for faster life histories, and possibly higher virulence, in the salmon louse Lepeophtheirus salmonis (Click here).

Behavioural ecology of host-parasite interactions

I have also been studying how parasitic infection affects host behaviour in wild passerine birds.

In southern France and Corsica (CEFE CNRS lab in Montpellier, click here) female blue tits Cyanistes caeruleus garnish their nests with aromatic plants. Via field experiments I have shown that by doing so they reduce bacterial loads on their offspring, especially those most infested with ectoparasites, which in turn makes them grow faster. This behaviour thus appears as a special kind of maternal care taking the form of preventive medication.

In populations of great tits Parus major studied by researchers from the EGI in Oxford (Click here) I have studied how avian malaria affects the social behaviour of hosts, and how bacteria are spread on social networks.
