Seascape genetics of saithe (Pollachius virens) across the North Atlantic using single nucleotide polymorphisms
Abstract The identification of isolated populations in widely distributed marine species is often impeded by low levels of genetic differentiation. However, modern genetic approaches now allow for the efficient detection of potentially large numbers of novel genetic variations, thereby improving the...

Abstract The identification of isolated populations in widely distributed marine species is often impeded by low levels of genetic differentiation.

The results suggest a potential mismatch between management and biological units across the Northeast Atlantic, which may have implications for sustainable exploitation of the species. |
