Description


The research groups at the Free University of Bozen-Bolzano, Italy, that deal with stable isotopes of water are mainly the Tree Ecophysiology and Ecosystems group (http://treeecophysiology.unibz.it/en/default.html) and the River Basin group (http://pro.unibz.it/staff2/fcomiti/web_comiti/RBG.htm).
 
The Tree Ecophysiology and Ecosystem group uses stable isotopes of water to determine the effect of drought and increased air temperature on water use efficiency of grassland species native of two alpine valleys characterized by two different rain regimes. In 2016, researchers of the Tree Ecophysiology and Ecosystem group  will use stable isotopes of water to determine the relative importance of different water sources (rain, snow, irrigation, and groundwater) on the grassland species of the same two alpine valleys.

The River Basin Group uses stable isotopes of water as environmental tracers in order to understand the water origin and water flow pathways in natural systems. Particularly, researchers rely on deuterium and 18-oxygen  to identify the water sources generating streamflow (such as rainfall, snowmelt, glacier melt, shallow groundwater) in high-elevation mountain catchments in Northern Italy. Moreover, isotopes are used in a joint ecohydrological research between the Tree Ecophysiology and Ecosystems and the River Basin group in order to investigate the main water sources (rain water, irrigation water, soil water and groundwater) used by apple trees in an Alpine valley and to assess the interaction of water fluxes between a river system and agronomic vegetation.
Reference persons: prof. Francesco Comiti, dr. Daniele Penna.
