    abstract = "Stable isotope compositions of carbon and nitrogen (expressed as delta
C-13 and delta N-15) from the European common cuttlefish (Sepia
officinalis) were measured in order to evaluate the utility of using
these natural tracers throughout the Northeast Atlantic Ocean and
Mediterranean Sea (NEAO-MS). Mantle tissue was obtained from S.
officinalis collected from 11 sampling locations spanning a wide
geographical coverage in the NEAO-MS. Significant differences of both
delta C-13 and delta N-15 values were found among S. officinalis samples
relative to sampling location. delta C-13 values did not show any
discernable spatial trends; however, a distinct pattern of lower delta
N-15 values in the Mediterranean Sea relative to the NEAO existed. Mean
delta N-15 values of S. officinalis in the Mediterranean Sea averaged
2.5 parts per thousand low than conspecifics collected in the NEAO and
showed a decreasing eastward trend within the Mediterranean Sea with the
lowest values in the most eastern sampling locations. Results sugge
delta N-15 may serve as a useful natural tracer for studies on the
population structure of S. officinalis as, well as other marine
organisms throughout the NEAO-MS."
