Natural geochemical markers reveal environmental history and population connectivity of common cuttlefish in the Atlantic Ocean and Mediterranean Sea
Natural markers (δ 13 C and δ 18 O stable isotopes) in the cuttlebones of the European common cuttlefish ( Sepia officinalis ) were determined for individuals collected across a substantial portion of their range in the Northeast Atlantic Ocean (NEAO) and Mediterranean Sea. Cuttlebone δ 13 C and δ 1...
