Research professional: Pierre Legagneux, PhD

I am a behavioral ecologist with broad research interests including community ecology, evolutionary ecology, conservation biology and animal eco-physiology. My current research activities fall into 3 main topics: i) Understanding trophic interactions in terrestrial Arctic communities ii) Identification of the mechanisms (eco-physiological) that affect life history traits in birds. iii)Development of a citizen science project involving children/parents and professors of primary schools. I obtained my PhD in population biology from Université Louis Pasteur de Strasbourg / Centre d’Études Biologiques de Chizé, CNRS France and did two post-docs on i) eco-physiology of Common eiders and Greater snow geese and ii) Terrestrial arctic ecosystem functioning (joined projects with Université Laval, UQAR and Environment Canada). I am available to work with QCBS students and researchers on different topics of their research projects:

  • Facilitating the planning and implementation of a collaborative research network between QCBS members and other strategic groups.
  • Revision of manuscripts, grant applications and research projects
  • Advises on statistical analysis of ecological data (mixed models, model selection) and planning experiments in ecology.
  • Scientific animation, networking, help on scientific communication
  • Assist QCBS members with the R software.
