Fish from urban tributaries to the Vermelho River, upper Paraguay River Basin, Mato Grosso, Brazil [PDF]
The fish fauna of urban streams is still poorly known, it difficult to assess the effects of urbanization expansion on fish species composition, for this reason the aim of this study was to provide a checklist of species that compose the ichthyofauna of ...
