Mobility project

Potential distribution of contrasting Douglas fir provenances under climate change

Species Distribution Models (SDMs) that generate predictions of future species ranges represent an important tool for guiding forest management. However, SDMs do not explicitly account for local genetic adaptation or phenotypic plasticity. Our objective is to improve predictions of species ranges by including intra-specific variability of response to drought events in SDMs. The IUFRO network of provenance trials will be used to evaluate variability in responses to drought for Douglas fir. Performances will be compared among sites of varying soil water deficit in order to calibrate SDMs. Distributions of contrasting provenances will be predicted in Europe, under current and future climatic conditions.

Biography & research interests

My research interest focus on the resilience of vegetation to varying aspects of climate change, such as altered disturbance regimes and increased drought events. I am motivated by understanding how ecophysiological responses to stresses at the plant level may translate into changes of ecosystem structure and function at broad scales. As part of my M.Sc., I analysed the diversity of plant traits related to drought resistance among saplings of tropical forest in French Guiana (Laboratory of tropical forest ecology in Kourou). I did my Ph.D. in Quebec, Canada, at the Centre for Forest Research. We examined post-fire ecosystem resilience of spruce-moss forests in the province of Quebec, and the long-term impacts on carbon cycling.

I am now a postdoctoral fellow at the EEF Research Unit (Forest Ecology and Ecophysiology), National Institute for Agricultural Research, Nancy. The objective of my research project is to compare survival and growth at provenance trial sites of varying water balance, in order to assess adaptation and phenotypic plasticity of Douglas fir populations. The results will be used to calibrate a species distribution model. Potential distributions of contrasting populations will be predicted in Europe, under both current and future climatic conditions. The predictions can guide foresters in the choice of suitable provenances, in order to mitigate the impacts of climate change. The AgreenSkills project was elaborated with N. Bréda and V. Badeau and is financed by the INRA metaprogram for Forest and Agriculture Adaptation to Climate Change (ACCAF).
