Interspecific hybridization in natural sturgeon populations of the Eastern Black Sea: the consequence of drastic population decline?
The eastern part of the Black Sea and its tributaries are suitable habitats for several sturgeon species, among which Acipenser gueldenstaedtii, A. stellatus, A. nudiventris, A. persicus, A. sturio, and H. huso are well documented. However, different threats have led these species to a dramatic decl...
