Is the interaction between waterlogging and drought a worsening factor in oak (Quercus petraea and Quercus robur) decline in Allier, Central France?
In Auvergne (center of France), forecasts show an increase of rainfalls in winter and spring, and of droughts in summer and autumn, with a marked increase of rainfall variability. The probable consequences for forests would be an increase of winter-spring waterlogging and marked summer or autumn droughts, with a strong potential impact on oak decline, by limiting tree growth and/or inducing a deficit of carbon reserves. Therefore our hypothesis is that interactions (succession) of waterlogging and drought periods progressively lead to carbon starvation, thereby weakening the tree facing other stresses, like for example its ability to harden a winter frost.
I did my doctorate at the Irrigation Department in the Centro de Edafología y Biología Aplicada del Segura (CEBAS-CSIC) (Murcia, Spain), as well as perform short research internships in Plant & Food Research (New Zealand), National University of Ireland (Ireland) and Universiteit Gent (Belgium). These training internships allowed me to acquire a wide experience in management of different types of sensors used to measure plant water status, which is of relevance in the postdoctoral research I am currently conducting. In addition, I could learn about different forms of organization and tasks that are involved in the development of an excellent research project. Until now, I have only worked on trees in orchard production. However with this mobility project, I will become familiar with the tree in the forest ecosystem, which is a good opportunity to increase my expertise in water relations. With this dual expertise, I should derive optimal rules of conduct for my future projects by analyzing the strengths and weaknesses of trees in both these ecosystems. Therefore, I can better contribute to responding to the current and future challenges of global change and forest conservation.
