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.

Europe has relatively low biodiversity compared to most other continents because many species became extinct during the ice ages. In subterranean ecosystems, however, which were shielded from climatic turbulences, a great diversity of ancient species were able to survive. This is the conclusion of a study on the amphipod genus Niphargus.
