Research Project


Altitudinal Gradients and Forest Response: Climate, Hydrology and Isotope Variability of a Mediterranean Ecosystem

Dendroecological, climatological and hydrological studies are combined to explain spatial and temporal oxygen isotope variability in tree rings and the hydrological cycle, which in turn contributes to a better understanding of palaeoclimate and hydrology in the western Mediterranean.

The hydrology part of the project focuses on the evolution of oxygen and hydrogen stable isotopes of water from precipitation over infiltration to the uptake by plants from soil and groundwater. Three of the main questions are:

  • How do high relief topography and seasonal variations in the position of the planetary boundary layer (PBL) influence the isotope altitude effect?
  • How do the isotope values of precipitation relate to the water vapor source region?
  • How is the δ18O value of precipitation reflected in soil water?
