IsoCycles, international conference on light isotopes of nutrients

15.10.2017 to 20.10.2017

Congressi Stefano Franscini, Monte Verità in Ascona, Switzerland

Reaching an integrated use of stable isotopes to constrain biogeochemical nutrient cycles

The improvement of analytical techniques and the substantial increase in the number of laboratories with the instrumentation required to perform isotopic measurements have boosted the number of studies using stable isotopes.
Stable isotopes of C, N, and S, and recently of O bound to P in phosphate, are powerful tools to trace sources, track transfers, and understand abiotic and biological processes and transformations of nutrients in the environment. However, although the biogeochemical cycles of individual nutrients are closely coupled, only a limited number of studies has attempted to combine stable isotope analyses of multiple nutrient elements.
This combination of stable isotope analyses offers new opportunities to better understand the drivers and consequences of changes in nutrient stoichiometry across ecosystems. Advancing a coupled stable isotope research agenda in the important area of nutrient biogeochemistry is the opportunity we seek to exploit through the proposed conference.
