We introduce the work providing a synthetic description of the diversity and phyletic structure
of freshwater fish in the Neotropical Region, especially emphasizing that of Brazil. This is …

Abstract Background The megadiverse Neotropical freshwater ichthyofauna is the richest in
the world with approximately 6,000 recognized species. Interestingly, they are distributed …

This study investigates whether (1) structural configuration (considering substrate
composition, wood debris, marginal and riparian vegetation) of streams suggests habitat …

A fish survey in 35 stream reaches (from 1st to 3rd order) with physicochemical and habitat
assessment in the São José dos Dourados system, southeastern Brazil, was conducted …

This study was carried out to develop and apply a fish-based biotic integrity index to assess
lowland streams in a highly deforested region of the Upper Paraná River basin. Fifty-six first …

Dam construction alters flow regimes and can change the composition of aquatic
communities. Using data from three Brazilian hydrographic basins, we tested the hypothesis …

Deforestation can modify stream habitat and the functional structure of fish assemblages.
The aims of this study were (a) to identify whether deforestation has a similar effect on local …

We compared the fish assemblage structure from streams with different intensities of
physical habitat degradation and chemical water pollution by domestic sewage in …
