International workshop “Isotope-based studies of water partitioning and plant-soil interactions in forested and agricultural environments”

27 – 29 September 2017, San Casciano in Val di Pesa, Florence, Italy

The workshop, organized in collaboration with the Universities of Bayreuth and Bolzano, aims to bring together scientists with different background (hydrology, soil science, plant physiology) but common research interests who use stable isotopes of water as tracers to study the partitioning of water in different environments. The workshop will tackle the urgent need to share experiences and advance knowledge about the hydrological and eco-physiological mechanisms that regulate the selection of different water sources taken up by trees in different conditions and settings, including cultivated species in agricultural environments. Indeed, despite the amount of work that is being currently conducted on topics related to the ecohydrological separation of waters in different environmental settings there are still unsolved issues that can affect our interpretation of isotopic data and hamper a thorough conceptualization of the complex functional interrelations between soil and vegetation. These issues include specific methodological approaches such as suitable extraction methods of soil water and xylem water, use of leaf water instead of water taken from stem cores, isotopic fractionation processes within the plant and associated with water uptake and transpiration.
