Deficiency syndromes in top predators associated with large-scale changes in the Baltic Sea ecosystem
Vitamin B-1 (thiamin) deficiency is an issue periodically affecting a wide range of taxa worldwide. In aquatic pelagic systems, thiamin is mainly produced by bacteria and phytoplankton and is transferred to fish and birds via zooplankton, but there is no general consensus on when or why this transfe...
