[IUFRO Div 8] WATCH NOW ONLINE Seminar by Nate McDowell on tree mortality in the Anthropocene

Dear all, Seminar #4 of the International Tree Mortality Network, an initiative of the IUFRO Task Force on Monitoring Trends and Patterns of Global Tree Mortality, is now available online. Watch this seminar at: https://youtu.be/vdAXQ8CibKA <https://youtu.be/vdAXQ8CibKA> *Dr. NATE MCDOWELL* _Rising tree mortality in the Anthropocene_ _Abstract_: Tree mortality is rising in most documented locations but the drivers and mechanisms of this trend are unknown. Changes in atmospheric carbon dioxide, temperature, and vapor pressure deficit, along with drought, are primary potential drivers. Mechanisms linking these drivers to mortality include water, carbon, and pathogen defense processes. These processes are interdependent such that failure of one can lead to failure of the others. Prediction of future mortality is challenged by our understanding of the mechanisms, however, some evidence suggests the growing mortality rates are likely to continue well into the future. I conclude by reviewing the numerous challenges and opportunities for predicting future tree mortality. _Nate is a senior scientist at Pacific Northwest National Laboratory._ He has studied tree mortality since the early 2000s, focusing on mechanisms and prediction. *Previous seminars:* Seminar # 1: Matt Hansen - Global forest monitoring using satellite data https://youtu.be/ya8XlQBS6DQ <https://youtu.be/ya8XlQBS6DQ> Seminar # 2: Flavia Costa - Tree mortality in the Amazon https://youtu.be/KoC8E6P3Zu8 <https://youtu.be/KoC8E6P3Zu8> Seminar # 3: Belinda Medlyn - Tree mortality in Australia https://youtu.be/hRlBc7oR328 <https://youtu.be/hRlBc7oR328> Visit us at: https://www.iufro.org/science/task-forces/tree-mortality-patterns/ https://www.tree-mortality.net/ -- --- Dr. (habil.)
