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.

Microbes self-organise to grow into fascinating and complex patterns. The diversity of these patterns depends on a previously unknown factor, as researchers at Eawag have discovered. This might re-define how we view the concept of microbial biodiversity.
