BoTWU: Marie Skłodowska-Curie Postdoctoral Fellowship
BoTWU will go beyond the state-of-the-art in tree water use research by (1) challenging the fundamental and long-standing TWU assumption in isotope hydrology, (2) unravelling the hydrological importance of the forgotten ‘upwards preferential flow’ in ecohydrologic separation, and (3) being the first to provide biophysical process-based knowledge to help boreal ecologists assess forest resistance and resilience to changing precipitation seasonality. It will be supported by up-to-date methodology and instruments, and an innovative experiment set-up. Particularly, high-resolution isotope data on roots to stems will be monitored with the latest in-situ non-destructive water isotope probes (WIP) and analyzed with the Picarro L2140-i. Synchronous half-hourly bi-directional sap flow in stems and roots will be measured also on roots and stems with the heat-plus-method SFM-4 sensors.
