The rio Machado is an large tributary of the rio Madeira, and investigations of the ichthyofauna are urgent given the current high threat of habitat loss on account of a hydroelectric plant under construction. Our inventory quantified 9,544 specimens, representing four orders and 38 species. Our study provides an unprecedented list of fish species from a poorly studied South American basin. This basin, which is considered one of the world’s biodiversity hotspots, presents high endemism, few cases of co-existence of phylogenetically related lineages, low species diversity, and few species occurrences with wide distribution. |
