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 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.

Rapid changes in the genome of two closely interlinked species cannot be explained only by processes such as evolutionary pressure. Equally important is the role played by ecological processes, for example the dynamics of population size. This has been shown for the first time experimentally by an international team of researchers under the direction of Eawag and the University of Konstanz with an alga and a virus. The study will be published today in the magazine Science Advances. Read more
