Biodiversity

Preserve biodiversity

Concerns about the preservation of biodiversity often end up on the losing side when it comes to weighing conflicting interests in the balance, and its loss is usually only quantified in financial terms when it is already too late. Eawag is researching what biodiversity really means, what benefits it brings, and what measures can be employed to preserve it.

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

Single-celled bacteria are capable of mixing water layers in lakes – not directly, by movement of their flagella, but by accumulating locally and thus increasing water density. The heavier water then sinks, creating circular currents. Researchers have now observed this process for the first time not just in the laboratory, but in a natural water body – Lake Cadagno (canton of Ticino). Read more
