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.

The lakes of East Africa are home to a surprising number of different cichlid species. This level of biodiversity has developed partly due to hybrids that managed to take over new ecological niches in their habitats, according to recent research carried out by scientists at the Swiss Federal Institute of Aquatic Science and Technology, Eawag, and the University of Bern.

Invertebrates on the beds of water bodies are observed closely, for they serve as indicators for the ecological status of running waters. A new Swiss-wide study by the aquatic research institute Eawag shows which species are especially good indicators, and how the monitoring and management of surface waters can be further improved.
