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.

In aquatic ecosystems, both mussels and macrophytes increase water clarity and generally help to prevent excessive algal growth. However, according to a study carried out at Eawag’s experimental pond facility, these stabilizing effects can be disrupted when the co‑occurrence of species gives rise to complex interactions.

Daphnia can adapt rapidly to changing environmental conditions. This was shown by a study carried out by scientists from Eawag and Cornell University in Oneida Lake (NY, US). This adaptation influences daphnia population density, thus affecting the entire lake food web.
