Welcome on my webpage!

I'm an associate professor of Ecology & Evolution at Toulouse 3 University (Evolution & Biological Diversity lab EDB). My research aims at understanding the evolution of physiological and behavioral responses of wild animals to biotic and abiotic stressors (pollution, urbanization, parasites) in the context of global change. I use comparative and experimental approaches in birds and fishes. Here you can find some information about my research and teaching activities.

New project
 
Of fish and men: ph
ysiological and behavioral responses to human-driven perturbations in freshwater fishes 

We just rece
ived a grant from Agence de l'Eau to launch the project! We focus on the effects of pollutants (pesticides and trace metals) on fish health at different biological levels, from molecules to the whole organism. We are testing whether some populations developed specific physiological or behavioral abilities to cope with water pollution, and how this can affect their ability to respond to parasites. We are using a combination of field and lab approaches on freshwater fishes (gudgeon, chub, brown trout). This is a collaborative project with several labs and colleagues. Jessica Côte (postdoc) and Quentin Petitjean (PhD candidate) just joined the team. Stay tuned for upcoming results! More info on this project  here.

1. Alternative strategies and wild immunology

Individuals of the same species respond very differently to parasites, but the causes and consequences of such intra-specific diversity remain unclear. We investigate the costs and benefits of immunity in variable environments. Because the costs of mounting an immune response are tightly linked to environmental factors (such as resource availability or pollution), we study how exposure to multiple biotic and abiotic stressors interact to shape the evolutionary trajectories of wild populations.


2.  Parental effects and evolution of immune defenses

I'm interested in how physiological and behavioral defenses against parasites and pollution are shaped across generations through parental investment.  During my PhD I focused on the transmission of maternal antibodies and its effect on parasite resistance in pigeons. Our current studies on fishes aim at understanding how parental exposure to parasites and pollutants can affect the behavioral and physiological traits of their offspring through parental effects.


3. Evolution of melanin-based coloration

Many vertebrate species display a wonderful color diversity, but the biological significance of animal coloration is still unclear. My various studies suggest that melanin-based coloration could be linked to individual strategies, with each morph being specialized in the exploitation of a particular microhabitat. For instance, darker pigeons seem better adapted to heavily urbanized and parasitized environments compared to paler ones. We are now testing whether color variability in birds and fishes (trout and gudgeon) could reflect alternative niche use and whether more variable populations are better able to cope with environmental perturbations, using a combination of experimental and comparative studies.

4. Adaptation to global change

Only a few species and particular behavioral types within a given species are able to cope with human-altered environments such as cities and polluted environments. We aim at deciphering which key physiological and behavioral traits are involved in the responses of birds and fishes to human-induced perturbations (pollution adn urbanization), and at understanding the evolutionary processes leading (or not) to local adaptation to human-altered environments. The next step will be to assess their consequences for population persistence, hoping to provide useful knowledge and tools for managers.
