The aim of this project is to construct and analyze models of évolution of compétition and cooperation between plants. Previous work by our group (Montazeaud et al 2020) has dealt with the evolution of plant height in response to competition for light. This theoretical framework must be extended in order to predict the joint evolution of size and shape, while accounting for trade-offs with fertility and for architectural constraints. These predictions should also allow designing selection schemes that promote plant cooperation. As a first step, a simple scenario of plant growth, where a first growth step is followed by a plastic resposne to the growth of neighbors, will be analyzed. In a later step, the evolution of plastic responses in continuous time could be considered.

- Analytical modelling of the evolution of social traits (main task)
- Numerical analysis of models, identification of evolutionarily stable strategies (main task
- Bibliographical analysis of architectural constraints (secondary task)
- writing scientific papers (main task)


- Basic concepts in evolutionary biology: evolutionary processes, applications of game theory.
- Mathematical modelling: elements of probability, dynamical systems. A knwoledge of optimal control theory would be appreciated.
- Knowledge of a language for symbolic computation (e.g., Mathematica)
- writing scientific papers in English

The condidates should have a PhD in a related discipline (e.g., evolutionary biology or game theory), and skills in modelling and computer programming. A knowledge of optimal control theory would be appreciated.

Work Context

This post-doc is part of the ANR-funded SCOOP project (https://umr-agap.cirad.fr/en/recherche/projets-de-recherche/scoop-cooperation-chez-les-plantes-cultivees), led by Hélène Fréville (AGAP, INRAE), which will use a combination of theory and experiments to identify above- and below-ground traits involved in social interactions and their associated cooperative phenotypes in crops (with durum wheat as an experimental model, as well as cooperative alleles. One aim of the project is to design selection schemes that promote plant cooperation and optimize crop yield in high-density agrosystems. The post-doc will be supervised by F. Rousset (CNRS, evolution of social behaviour) at the Institut des Sciences de l'Evolution (ISEM), and will benefit from the expertise of different project members, including S Gandon (CNRS, development of kin selection models) and H Fréville (INRAE, experiments on kin selection in crops).
