From ecology to genetics and back: the tale of two flounder species in the Baltic Sea

Recent years have brought the realization that evolutionary changes driven by selection can occur in ecological time scales. However, recent evolutionary events can be hard to detect and may easily go unnoticed. For harvested species, such cryptic diversity may lead to suboptimal management. These points are illustrated by the two flounder species in the Baltic Sea. Although early ecological studies identified two ecotypes of European flounder...
