Isotopic niche areas calculated with SEAC (see Table 6 for the ellipse area, credibility interval and overlap area values) for Franciscana dolphin (Pb), South American fur seals (Aa) and South American sea lions (Of) during the three major periods in the recent history of marine resource exploitation in Uruguay (see Supplementary Fig. S1). δ13Ccor and δ15Ncor: values corrected for isotopic baseline shifts (see original data and sample size in Table 2 and Supplementary Table S1).
