    Stable isotopes indicate population structuring in the southwest Atlantic population of right whales (Eubalaena australis). by Morgana Vighi, Asunción Borrell, Enrique A Crespo, Larissa R Oliveira, Paulo C Simões-Lopes, Paulo A C Flores, Néstor A García, Alex Aguilar

    Published 2014-01-01
    “…Results indicated significant differences between the two sampling areas, being δ13C and δ18O values significantly higher in samples from southern Brazil than in those from central Argentina. This variation was consistent with isotopic baselines from the two areas, indicating the occurrence of some level of structure in the Southwest Atlantic right whale population and equally that whales more likely feed in areas commonly thought to exclusively serve as nursing grounds. …”
