Wood formation and tree adaptation to climate

Wood plays key roles in living trees, providing not only mechanical support but also storing and transporting water and nutrients to the leaves, thus allowing them to fix carbon. For this reason, wood characteristics are important in determining the ability of a tree to face environmental cues, including climate change. Indeed, under normal climatic variability, wood anatomy, structure and function usually fit the environmental conditions the trees are living in. However, under a strongly and rapidly changing climate these characteristics need to be adjusted to fit the environmental conditions through phenotypic plasticity and/or evolutionary adaptation.
To promote a sound and future oriented management of forest resources it is fundamental that tree breeders and forest managers select and promote individuals, provenances and species that best fit the future conditions. It is therefore important and urgent that plant scientists provide tools and knowledge helping to identify and select the most relevant adaptive traits.
With this conference, we aim at gathering experts from different disciplines to present, exchange and discuss their recent advancements related to a better understanding of plant adaptation to climate, with special focus on the trees. The conference will be held on May 23-25 in Orléans (France) and will include five successive sessions, namely:
1)    Environmental and/or genetic control of wood formation
2)    Methodological developments for the study of wood formation and tree adaptation to climate
3)    Potential adaptive wood traits, future selection traits: which and why?
4)    Ecophysiological approaches to wood functioning
5)    Wood/Climate modeling and information systems

Main topics

Tree rings, climate change, evolutionary adaptation, phenotypic plasticity, cambial activity, cell profile, seasonal growth, process-based simulation.

Hôtel Dupanloup : 1, rue Dupanloup - 45000 ORLEANS - FR

The conference venue is unique. Located right next to the Orléans’ cathedral, the episcopal palace of Orléans, built between 1635 and 1641, locally known as the Hôtel Dupanloup, is a classical French building which served until 1905 of residence to the bishops of Orléans.  Since 2014, the renewed palace hosts the International University Center for Research and Le Studium Loire Valley Institute for Advanced Studies.

Participants will be welcomed in this exceptional surrounding, blending Middle Age and Renaissance cultures with modern design and will have the opportunity to discover French cuisine and wines.


IMPORTANT ! Please note there are works on the train line between Paris and Orléans during the day: no train between 09h30 and 16h30. Furthermore, there is a scheduled strike on Wednesday 23th & Thursday 24th May with a limited number of trains (all lines in France are concerned).
