High Connectivity of the White Seabream (<i>Diplodus sargus</i>, L. 1758) in the Aegean Sea, Eastern Mediterranean Basin

Population dynamics in the marine realm can shape species’ spatial structure and genetic variability between given geographical areas. Connectivity is an important factor of species’ population structure. In this study, we examined the genetic diversity and structure of white sea...
