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.

Groundwater is also an ecosystem, but little is known about the biodiversity underground. Eawag researchers have now documented the diversity of life in Swiss groundwater in a pilot study – and discovered previously unknown species of amphipods in the process. Here they relied on a citizen science approach.

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.
