Tributaries as richness source for Oligochaeta assemblage (Annelida) of Neotropical dammed river
Brazilian Journal of BiologyTributaries may serve as richness source for the river main channel and the zoobenthos community is a good tool to verify this kind of pattern. In this study, we aimed to characterize the benthic invertebrate assemblage in three tributaries associated to
