In charge of the INRAE International Priority Program “Adaptation of forests and agroforests to climate change”. Research activity: study of adaptation of forest trees to climate in natural and artificial forest tree populations. Investigation of evolutionary adaptation and adaptive phenotypic plasticity based essentially on annual rings and wood formation studies. Co-director (with A. Martinez-Meier from INTA, Argentina) of the International Associated Laboratory between INRAE, France, INTA, Argentina and University of Huanta, Peru: FORESTIA [https://www6.inrae.fr/forestia/].

Current and projected changes in climate are estimated to be from 10 to 100 times faster than the natural adaptive capacity of trees whose generation times are long. As extreme climatic events are becoming more frequent and exert a strong selection pressure on tree populations, there is an urgent need to better characterize the genetic variability involved in the response of trees to climate. There is currently a lack of knowledge on the role of genetic variability in tolerance to climatic...
Climate change threatens forest trees. Their ability to resist depends on their potential to adapt. Phenotypic plasticity, i.e. the potential for individual adaptation, is a rapid mechanism that can allow trees to adjust to new climatic conditions. Tree-rings allow retrospective estimation of phenotypic plasticity of wood formation to climate in forest trees. In this study we show how to estimate linear reaction norms of annual ring variables as a function of climate. We use the slope of t...
