Primary Productivity in Large Lakes
Between 2018 and 2021, the Limnology Center hosted the integrative and interdisciplinary project Primary Productivity in Large Lakes. The overall aim of the project was to improve our understanding of short- and long-term dynamics in primary production in large lake systems, related to nutrient changes and climate warming. The project has answered why the primary production in Swiss lakes has remained nearly stable while phosphorus concentrations have drastically dropped over the last decades.
This project was the first connected to LéXPLORE platform and was led by a consortium from EPFL, University of Lausanne, University of Geneva, University of Applied Sciences and Arts of Southern Switzerland, Eawag, University of Constance and INRA-Thonon-les-Bains.
