Dietary and niche analyses of four endemic and sympatric batoid species of the subtropical South Atlantic Ocean ...
We aimed to characterize the trophic ecology and test the hypothesis of niche overlap between four sympatric batoid species of the subtropical South Atlantic. Data were collected between 2017 and 2022 from two artisanal fishery communities in southern Brazil. Batoid’s stomach contents were identifie...
