Aquatic Ecosystem Research Group


Our working group studies aquatic biodiversity from the poles to the equator. Specifically, we utilize modern genomic tools to understand processes underlying the origin, distribution and adaptation of aquatic organisms.

Stressor research

Our working group analyses the effects of single and multiple stressors on aquatic ecosystems from genes to ecossytems

more aboutStressor research


We are developing modern genetic tools to assess aquatic biodiversity with much greater resolution.

Polar Biology

In several third-party funded projects we are studying how the fascinating diversity of Antarctic invertebrate species have originated. A special emphasis is placed on Southern Ocean sea spiders (pycnogonids).

Population Genetics

Using different molecular markers we analyse patterns of population diversity and connectivity of species in marine and freshwater habitats. Specifically we ask, how anthropogenic modifications of the habitats have impacted on populations.
