The relationships between diet and morphology, diet and taxonomy and morphology e taxonomy were examined using Mantel test. And we test the relationships between diet and morphology after retire the effect os taxonomy using Partial Mantel Test. We used RDA to explore relevant attributes to diet. Results show that, independently of Taxonomy, some of the trophic guilds could be grossly predicted from few relevant morphological attributes (i.e mouth width and mouth Height especially for piscivores and carnivores) and thus suggest a significant link between diet and morphology. In other words, species having similar diet tend to converge to some extent on some morphological attributes. / O objetivo deste trabalho foi explorar as relações entre dieta, morfologia e taxonomia de 30 espécies capturada no Reservatório de Serra da Mesa. As relações entre dieta e morfologia, dieta e taxonomia e morfologia e taxonomia foram testadas utilizando o teste de Mantel. E a relação entre dieta e morfologia, após retirado o efeito da taxonomia foi testada utilizando o teste de mantel parcial. Foi utilizada uma RDA para analisar quais características são importantes para as diferentes dietas apresentadas. Os resultados demonstraram que, independente da taxonomia, algumas guildas tróficas podem ser preditos a partir de alguns atributos morfológicos relevantes (i.e. altura e largura da boca para píscívoros e carnívoros) e sugere relação significativa entre dieta e morfologia. Ou seja, espécies que possuem dieta similar tendem a possuir características morfológicas semelhantes.
