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 Switzerland – not to mention the rest of Europe and the United States – freshwater fish are falling victim to a deadly disease that is rampant in the summer and dormant in the winter. It is caused by a parasite that thrives in rivers and attacks salmonid fish in particular. Researchers from EPFL, Eawag and University of Bern have come up with a mathematical model for predicting outbreaks as part of a three-year joint research program. Read more

In a laboratory experiment, Eawag ecologists studied how the pond snail Lymnaea stagnalis is affected by heatwaves, which are expected to become more frequent as a result of climate change. Snails exposed to temperature stress showed a greater investment in reproduction, egg production increasing by 60 per cent on average.  Read more
