Project: Transfer of pigments and vitamins in the aquatic food web

Some top predators in the Baltic Sea suffer from deficiency syndromes that are thought to be caused by low levels of pigments and vitamins. We study how these deficiencies arise.

About the project

These substances are produced by bacteria and phytoplankton and are transferred by zooplankton to fish and birds. The overall aim of this project is to understand the factors regulating the transfer between trophic levels and to explore possible links between these processes and deficiency syndromes in top predators.

We perform both field samplings and experimental studies. Pigments and vitamins are quantified with high-precision liquid chromatography (HPLC).
