Stable oxygen isotopes reveal habitat use by marine mammals in Rio de la Plata estuary and the adjoining Atlantic Ocean

Detailed knowledge on habitat use by marine mammals is critical for understanding their ecological role and for adequate management. Here, we assess the habitat use patterns of thirteen species of marine mammals along the salinity gradient of the Río de la Plata estuary and the adjoining western Sou...
