Abstract
Understanding how functionally similar species segregate resources to minimize competition is vital for predicting
evolutionary factors and patterns of coexistence. We conducted a study in Mata de Itamacaoca, in the middle Munim
River basin, Maranhão, northeastern Brazil, to characterize the functional morphology and trophic niches of five
coexisting Characiform species in this area - including a recently described species, and to investigate whether their
functional morphology is a key determinant of their trophic niches. Our analysis of functional morphology and diet,
employing linear measurements to predict dietary specializations, showed that these species are predominantly
generalist insectivores with a significant morphological overlap. This study underscores the influence of species’
natural history on their ecological characteristics, contributing to more effective conservation strategies.
