Oscar Nordahl | lnu.se

My names is Oscar Nordahl and I am enrolled as a PhD-student in Ecology at the Linnaeus University Centre for Ecology and Evolution in Microbial model Systems (EEMiS). I utilize the coastal fish community in the Baltic Sea as model system to study barriers to gene flow and local adaptations on a fine spatial scale. This is achieved by the use of a wide array of techniques: molecular tools to study genetic barriers; field and laboratory experiments to study local adaptations; field studies to detect phenotypic variation among populations.
