Researcher
Department of Marine SciencesAbout Marlene Jahnke
Background
Docent (2023, University of Gothenburg) in Marine Ecology and PhD (2016, Station Zoologica Anton Dohrn, Italy/Open University, UK) in Biology. Born (1984) in Germany, MSc in Biology from the University of Konstanz, Germany, as well as CSIRO and University of Canberra, Australia.
Research
I am a molecular ecologist with a focus in conservation genetics. I am interested in exploring how population genetic information can be used for conservation purposes with state-of-the-art methods, for instance for the establishment of protected areas, monitoring, restoration and understanding adaptability to climate change. I have strong interests in seascape genomics, adaptive vs. non-adaptive evolution and the evolution of sexual vs. asexual reproduction.
Currently I am a researcher at Tjärnö Marine Laboratory, University of Gothenburg, working on two projects for which I am the main PI. The first is a FORMAS research project for early-career researchers (2021-2025), and we are working on generating genetic information for Baltic Sea eelgrass, which is threatened by climate change. The second is a VR project (2023-2026) aiming to predict survival and adaptation of eelgrass in the seascape and validate those predictions with mesocosm experiments. I am also very involved in a multi-partner FORMAS project on adaptive eelgrass restoration, the Horizon project MarHAB, the Interreg project BlueBioClimate, the project SAMSKAG supported by the Nordic Council of Ministers, and the Norwegian research councli project NORSE. See the links below for more information. I am also part of the research group Zorro (Zostera restoration) and the Centre of Marine Evolutionary Biology (CeMEB).
