Welcome to the CEFE

The CEFE is currently the largest French research center in Ecology and Evolutionary Ecology. Our Mission: perform independent, fundamental scientific research on the dynamics of biodiversity, planetary environmental change, and sustainable development. The links between society and ecology is a theme of increasing importance in oour research.

If you are interested in who does what on a specific theme or topic at CEFE, please go to the WHO DOES WHAT tab and use the proposed tags. You will have direct access to the pages of the persons listed for a given tag.

If you are interested in what the different research Departments at cefe do and the focus of their respective teams, please go to the RESEARCH tab and navigate the Departments and their teams.

Hugo Gruson

PhD in evolutionary biology on "Origin and functions of iridescent colours in hummingbirds"

Although well-spread in marine organisms, iridescent colours are rare and restricted to a small number of groups on terrestrial animals. Yet, one group displays striking iridescent colours: hummingbirds. Iridescence in hummingbirds has reached an astonishing level of complexity and lead to highly reflective and highly directional colours.

This raises a large number of questions: What are the properties of the nanostructures responsible for iridescence? How did iridescent colours evolve in hummingbirds and what consequences does it have? What are the links between iridescence and other common ecological phenomena: competition, habitat filtering, sexual selection, etc.?
