Biodiversity of Arctic fishes: first karyological information on Gaidropsarus argentatus (Reinhardt, 1837), a new piece to the puzzle
As widely acknowledged, climate changes are occurring at a very fast pace in the Arctic region, leading to inevitable changes in the Arctic marine ecosystems, therefore baseline information on the current status of marine fish diversity is both essential and urgent. In this context, we provide the f...
