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.

In the past, Lakes Zurich and Greifen have repeatedly been affected by blooms of potentially toxic cyanobacteria. This was confirmed by an analysis of sedimentary DNA carried out by Eawag scientists. Read more

The residual flow in the Sarine River is insufficient to maintain its dynamic flow. Research is currently being carried out as part of the “Energy Turnaround” National Research Programme (NRP 70), to ascertain whether hydropower can be made more environmentally friendly through controlled experimental flooding. The first experimental flood event has taken place, and researchers are now analysing all the data and records that have been collected. Read more
