Presentation

I am a plant community biologist. My main interest is to link the ecological response of a plant to abiotic and biotic variations in a community with ecophysiological processes. How resources, environmental conditions alter plant functions and the trait associated with their ecological strategy is a kind of broad questions I address. Then I look at how plants respond in a community to propose a mechanistic explanation of community functioning.

Research

In SLU, I focus on gross primary production (GPP) of the boreal forest. In Scots pines forest, I use sap flux data and stable carbon isotope to calculate water use efficiency and infer GPP. This approach aims to bring a way to check for eddy-covariance measurements and provides an efficient method applicable where eddy-variance is not. I carry out the same method in a mixed forest. It would allow us to partition the GPP flux into the different species (birch, Scots pine, Norway Spruce).

Background

I previously worked on several projects:

- recovery of temperate grassland after a severe drought, with a focus on root functional traits (INRA-UREP, Fr)

- the role of resource availability on biotic interactions between oak seedlings and Poacea (INRA/UCA-PIAF, Fr)

- plant gas exchanges in weightlessness (Institut Pascal-CNRS, Fr)
