Abstract: Diet and morphology of Serrapinnus notomelas and Serrapinnus sp.1 were investigated across ontogeny, as a way to elucidate the key elements linked to the resource partitioning (a main driver for species coexistence). Fish sampling was conducted monthly between October 2010 and March 2012. Individuals were captured, identified, and classified into juvenile or adult. Our results show ontogenetic and interspecific differences in feeding abilities and morphological traits. Differences in body shape (relative area … Show more

“…This result indicates that the diet between individuals within each population and between populations are homogeneous. Studies report that homogeneous diets may indicate the partitioning of food resources favoring intraspecific coexistence and population stability (Neves et al, 2018;Soares et al, 2020;Kliemann et al, 2021). Thus, we assumed that the homogeneity in the diets and the high consumption of algae and macrophytes indicate the partitioning of resources.…”
