DUTOIT THIERRY

Subjects taught
My teaching consists of seminars on ecological engineering and ecological restoration in Master 1 and 2 environmental courses in France, Belgium (University of Liège) and Germany (Universities of Jena and Rastibonne) as well as numerous visits to our workshop sites on these themes, particularly in the Crau plain (Bouches-du-Rhône, France).ORCID identifier

Research topics
Director of research at the CNRS within theEcology and Environment Institute Since 2012, the main aims of my research have been to gain a better understanding of the assembly theories that govern the composition and organisation of plant communities. The aim is to be able to answer fundamental questions about the biodiversity of these communities and their dynamics, even over the very long term (several centuries to millennia). My results are then applied to the conservation management or ecological restoration of ecosystems using nature-based solutions (ecological engineering, rewilding, passive restoration, etc.). My main workshop site is the sub-steppe grasslands of the La Crau plain in the Bouches-du-Rhône département. My main discoveries have been to demonstrate the very low resilience of herbaceous plant communities in the face of human disturbance regimes, even over the very long term, and the importance of biotic relationships (facilitation) in the processes of their ecological restoration via the role in particular of certain ecosystem engineers such as insects (harvester ants) or plants (nurse plants). In terms of research governance, I was deputy director of theMediterranean Institute of Biodiversity and Ecology (UMR IMBE) between 2019 and 2023 and deputy director of the Tersys Federative Research Company between 2017 and 2021.
