| Lineage | Whiskers from 10 tracked southern sea lion juveniles, 22 tracked adult females (1 Turn Island, 5 Kelp Island, remainder Big Shag island) and 8 tracked adult males (all in Big Shag island) were analysed in lab to read stable isotope values. The instrument used was Carlo-Erba elemental analyser interfaced with a Finnigan Delta Plus XP mass spectrometer (Light Stable Isotope Lab, University of California Santa Cruz, Santa Cruz, CA, USA). Data were corrected for sample mass and instrument drift. Measurement precision (standard deviation), based on within-run replicate measures of the laboratory standard (pugel), was 0.06 ? for carbon (13C) and 0.08 ? for nitrogen (15N) isotope values. |
