Climatic impact on functional wood anatomy, seasonal wood formation, and tree growth along altitudinal gradients on Corsica
Final Report Abstract
The dendroecology project was one out of four projects within the bundle project CorsicArchive. It analysed tree growth of two native pine species rates along climatic gradients at different temporal resolutions and related long-term and seasonal growth variations to climatic variables and the controlling weather patterns. We found that the climate factors controlling tree growth generally shift from precipitation to temperature towards high elevations, but even close to the tree line tree growth is limited by moisture availability during the summer months. The wood anatomical investigations shed more light on IADF formation in co-occurring Mediterranean pine species and their environmental control. The combination between wood anatomical approaches, high-resolution dendrometer measurements and synoptic climatology led to new ways how to integrate tree growth data and regional weather patterns. The exact dating of intraannual stable isotope tree-ring data with the help of cambial growth models is a new approach that will improve the explanatory power of high-resolution stable isotope analyses in tree rings. Beside of scientific publications, project results were also presented to public stakeholders and policy makers during a workshop in Corsica that led to public awareness and media reconnection in local newspapers, but also in nationwide French newspapers such as Le Figaro. After the results will be published, all data sets of the dendroecology project’s publications will be made available on the open access long-term data repository PANGAEA (www.pangaea.de).
