Symposium Drought, plant hydraulic traits and vegetation modeling

Date: 04 September 2018
Location: Room C0326, Forum Building, Wageningen University Campus

Many ecosystems around the globe have experienced frequent and severe droughts in the past two decades. These extreme events have caused large-scale tree mortality and negatively affected the carbon balance of several ecosystems, including significant losses in crop production. Recent studies suggest that plant hydraulic traits are important to predict the risk of drought induced mortality and the distribution of vegetation across climatic and hydrological gradients. In this symposium, we will provide a forum for recent breakthroughs and syntheses in the field of plant hydraulics and its links to ecosystem functioning and resilience. Speakers will address diverse topics, from tree hydraulic performance under drought and the physiological thresholds that trigger mortality, to the role of climate and hydrology as drivers of hydraulic trait variation at the global scale. The symposium will also address novel process-based models that predict mortality and productivity at the tree and ecosystem level and novel methods and approaches to measure plant drought resistance.
