Ecosystems

Understand and manage ecosystems

Why does one species of toad live in ponds, while another prefers shingle banks? How does the flora and fauna in a mountain stream change when the glacier has melted away? And how do invasive species affect their new habitat? It is only by answering questions such as these that entire ecosystems can be understood and, to some extent, managed.

May 13, 2022As of 1 May 2022, Andrin Krähenbühl will head the FIBER fisheries advisory service at the Swiss Federal Institute of Aquatic Science and Technology (Eawag) in Kastanienbaum. The biologist and angler brings with him experience from research and association work. And he is convinced that it serves everyone if the institutions work well together: fisheries, research and biodiversity.

Current research projects

This Interreg project aims to understand the responses of Lake Constance to changing environmental conditions.
In order to better understand natural processes and also to be able to better control the activities of microbial communities in technical systems such as wastewater treatment plants, we need to understand how microbial communities work.
A new multidisciplinary research platform for Lake Geneva
How to investigate the spatial variability in lakes?
Heterogeneous data platform for operational modeling and forecasting of Swiss lakes in collaboration with the Swiss Data Science Center.
