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.

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
