Project: Transfer of thiamin in the microbial food web (MicroThi)
Thiamin (vitamin B1) deficiency cause behavioural and reproductive disorders leading to mortality in fish and birds. The aim of the MicroThi project is to quantify thiamin (B1) production and transfer from lower to higher tropic levels in the Baltic Proper.

More about the project
Deficiency of the essential vitamin B1 (thiamin) is an issue affecting behaviour and reproduction negatively in several fish and bird populations. Wild populations around the Baltic Sea seem to be severely affected but the reasons behind thiamin deficiency have not yet been resolved.
Recent modelling studies suggest that increased abundance of small flagellates and picoplankton coincide with a reduced flow of thiamin to higher trophic levels. Hence, a shift in the microbial food web can play a key role in regulating the transfer of this micronutrient in the system.
The aim of this project is to quantify thiamin production and transfer from lower to higher tropic levels in the Baltic Proper under plankton community shifts and different base line levels of thiamin. The project will provide new insights into the causes of thiamine deficiency and the efficiency of thiamin transfer in the marine food web.
