Management of a highly unlikely native fish: The case of arctic charr Salvelinus alpinus from the Southern Alps
Abstract As a result of ancient introductions, some alien species are erroneously considered native. Salvelinus alpinus (Linnaeus, 1758) is hypothesized to have survived as a postglacial relic in the northern European Alps, although documented ancient introductions contradict its native status in a...
