Department Fish Ecology and Evolution

Fish Ecology & Evolution (FishEc)

We study ecology, evolution and biodiversity of fishes and other aquatic organisms. We are interested in the mechanisms that drive the origins, the maintenance and the loss of species, genetic and functional diversity.

In just 16,000 years, more than 500 cichlid species, distributed throughout the entire food web, have evolved in Lake Victoria. This explosion of biodiversity was made possible by repeated cycles of fusion and diversification in evolutionary lineages, as researchers from Eawag and the University of Bern have described in the “Science” and “Nature” journals. The results underscore that it is not just species that need protection, but entire “species swarms”.

Research Projects

Establishing a framework for conservation genomics of freshwater biodiversity
We study the biodiversity of Swiss freshwaters and design data-driven conservation strategies that take climate change and human impacts into account.
In this project we are interested in which traits govern the efficiency of stickleback foraging in different ecological contexts.
This project contributes to the Blue Green Biodiversity Research Initiative
