Bayesian results of the variation in δ13C and δ15N values for the Guiana dolphin Sotalia guianensis from the Northeastern coast (NC) and Amazon Estuary and adjacent coastal zone (AE), respectively (Sgui_NC and Sgui_AE). Black circles represent the SEA mode. Boxes indicate 50%, 75% and 95% credible intervals from dark grey to light grey, respectively. Red squares indicate the SEAc (SEA corrected for small samples sizes) of Bayesian standard ellipse areas.
