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.

Although use of the fungicide hexachlorobenzene has been banned since 2004, this compound is chemically stable – and accumulates in the polar regions where humpback whales replenish their fat reserves each year. Cell line studies conducted at Eawag have now shown that, while hexachlorobenzene does not have acute toxic effects, it can cause damage to DNA in humpback whale cells.

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.
