Potential distribution of contrasting tree provenances under climate change: accounting for intra specific variability of drought response in species distribution models

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 stress. 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. I did my Ph.D. in Quebec, Canada, at the Centre for Forest Research. We examined post-fire ecosystem resilience of sprucemoss forests in the province of Quebec, and the long-term impacts on carbon cycling. In 2014, thanks to AgreenSkills, I obtained a postdoctoral fellowship at the EEF Research Unit (Forest Ecology and Ecophysiology), INRA, Nancy. The objective of my research project was to compare survival and growth at provenance trial sites of varying soil water deficits in order to assess adaptation and phenotypic plasticity of Douglas fir populations. The results were be used to calibrate a species distribution model. This project aimed at predicting potential distributions of contrasting populations 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. Breda and V. Badeau and was financed by the INRA metaprogram for Forest and Agriculture Adaptation to Climate Change (ACCAF). I am currently working at the Centre Regional de la Propriete Forestiere at Nancy.
