Twenty-one nominal species of Hypostomus are recorded in fresh and brackish waters of
the Guianas from the oyapock to the essequibo rivers. one of those, Hypostomus …

This study addressed the feeding ecology of fish fauna from a first-order stream located in a
rural area. The purposes were to evaluate the influence of interspecific, seasonal and spatial …

Eleven ecomorphological attributes and diet of seventeen juvenile fish species were
examined to test the hypothesis that morphological patterns determine resource uses in …

This research aimed to understand how anthropic impacts generated by sugarcane
plantations and urban development affect a Neotropical river in northeastern Brazil, through …

This study investigated the morphological and dietary relationships of the fish assemblage in
a stream with an endemic fauna and low species richness. The ichthyofauna was sampled …

Understanding variability in the composition of aquatic assemblages requires a multiscale
perspective, since processes operating at different spatial scales (from regional to local) …

We tested the effects of ruralization and urbanization on the functional diversity indices and
the composition of functional traits of Neotropical stream fish communities. The study was …

Resource partitioning allows for interspecific coexistence and is frequently reported for
similar species. Here, we predicted the existence of resource partitioning among species of …

The aim of the present study was to evaluate factors that may favor the coexistence of three
endemic species of Astyanax (Astyanax bifasciatus, Astyanax minor and Astyanax …
