General interest

The main focus of our research is morphological variation. This is because variation is the raw material for selection: its amount and nature condition the evolutionary possibilities. Using geometric morphometrics we quantify patterns of shape variation and evolution at various scales using diverse models. We try to place our research at the junction of structural biology (molecular developmental genetics), functional biology (population biology/biomechanics) and phylogeny (historical dimension). Acounting for the real complexity of development-environment interactions is a major challenge of modern evolutionary biology.



Current projects


Evolution of wing shape and color in Morpho butterflies




Why are the Morpho blue? How do wing shape and color co-evolve? This project aims at understanding the evolution of wing shape and color patterns in Morpho butterflies.

This is a collaboration with Violaine Llaurens,
Marianne Elias, Nicolas Chazot, Ramiro Godoy-Diana and Patrick Blandin.

This is the Master project of Camille Leroy.




Genetics of Fluctuating asymmetry






What are the developmental and genetic bases of developmental stability? Using the amazing tools of Drosophila genetics, we study the genetic/epigenetic aspects of the control of Fluctuating Asymmetry in Drosophila melanogaster. This is a project led by Fred Peronnet.


Other projects include the effects of various pollutants on arthropod  morphology (Chironomus and Gammarus) with Hélène Arambourou.  






G matrices and phenotypic plasticity in Drosophila suzukii





We are investigating the evolution of G matrix of wing shape in the context of the european invasion of Drosophila suzukii, that provides a unique opportunity to quantify the effects of strong selection and drift on G.

This is Antoine Fraimout's PhD project, in collaboration with Celine Teplitsky, Simon Fellous, Nicolas Navarro and Patricia Gibert.

Various other things on Drosophilid evolution with Jean David, Nelly Gidaszewski, Amir Yassin.
