The postdoc aims at comparing biomass allocation between a set of crop plant species already available in the CROPTRAITS database (https://erc-constraints.cefe.cnrs.fr/database-croptraits/). Based on this comparative approach, the postdoc will use models developed in ecological theory to (1) assess the degree of variability in biomass allocation to vegetative and reproductive structures between and within species, (2) test allometric models of trait variation, such as the metabolic scaling theory, to explain this variability in crop plants, (3) refine the models if necessary or, alternatively, propose new models of biomass allocation, and (4) determine whether the allometric models enable predicting plant heterosis in crop species.
The postdoctoral fellow will be assigned to the Centre d'Ecologie Fonctionnelle et Evolutive (CEFE, UMR5175, CNRS Montpellier; https://www.cefe.cnrs.fr/fr/) within the ECOPAR team, and will be supervised by Cyrille Violle (CEFE), François Vasseur (CEFE) and Denis Vile (UMR759, INRAE Montpellier). He/she postdoc will be funded within the framework of two ERC projects led by Cyrille Violle and François Vasseur.


- analyze the biomass-growth and biomass-reproduction relationships on a set of cultivated plant species (main task)
- test the ability of mathematical models formulated in comparative ecology, such as the metabolic theory of ecology, to explain the performance of crop species (main task)
- Participate in the formulation of new models if necessary and, where appropriate, valorize them in the form of scientific publications (main task)
- collect, organize and structure available data on the species grown in the host laboratory, as well as from collaborators and the scientific literature (secondary task)
- participate in ongoing experiments to collect new phenotypic measurements on different plant species (secondary task)


- Good knowledge of plant ecology and of models developed in comparative ecology.
- Training in agronomy will be appreciated but is not essential.
- Mastery of statistical analysis tools (office and R pack in particular)
- Rigor and ability to structure large data sets
- Mastery of spoken and written English
- Ability to write scientific articles
- Ability to work in a team

Work Context

The CEFE is one of the most important ecological research laboratories in France. CEFE's project aims to understand the dynamics, functioning and evolution of life, from "bacteria to elephant" and "from genome to planet". It is based on three ambitions: 1] to understand the living world in order to anticipate what tomorrow will bring, [2] to lead to innovations and meet society's expectations; [3] to practice a science that is "unifying" and diverse in its disciplinary approaches. The research questions are posed in a context marked by global changes, the development of new technologies for the manipulation of life, and society's growing demand for research.
The CEFE is organized into four scientific departments surrounded by common technical platforms (1. Ecologie Evolutive, 2. Biodiversité et Conservation, 3. Ecologie Fonctionnelle, et 4. Interactions, Ecologie et Sociétés).
