Teaching

Emil Fridolfsson teaches in the courses “Marine Ecology” and “Discovery of a Sustainable Baltic Sea”.

Research

Emil Fridolfsson carries out research in aquatic ecology studying food web transfer of micronutrients.

Studies are carried out in both brackish and marine systems in temperate regions. Currently, he is focusing on the transfer of thiamin (vitamin B₁) in the Baltic Sea food web. This micronutrient is produced by bacteria and phytoplankton and transferred via zooplankton to fish and birds. Several top predators are displaying symptoms of vitamin deficiency and the aim is to understand the basis of these environmental disturbances.

Thiamin content of common phytoplankton and zooplankton species and the transfer between them is investigated in experiments and field studies. The relationship between thiamin deficiency and underlying environmental factors is investigated using monitoring data.
