Thiamine deficiency and declining bird populations in the Baltic Sea Region

The Swedish Agency for Marine and Water Management (SWAM) commissioned Mistra EviEM to evaluate the current understanding of the link between a lack of vitamin B1 (thiamine) and the declining bird populations in the Baltic Sea region.

According to EviEM’s pilot study, current scientific evidence for the thiamine deficiency hypothesis is insufficient for conducting a systematic review on the thiamine deficiency hypothesis.
