  abstract = {{H}abitat connectivity is considered a central factor shaping ecological communities, and the effects of waterway barriers such as natural waterfalls on fish movements are expected to produce differing assemblage structures in riverine ecosystems. {H}ere, we evaluate the influence of a sequence of waterfalls on the compositional dissimilarity of fish assemblages along the {M}adeira {R}iver, the largest tributary of the {A}mazon {R}iver. {W}e found significant differences in species composition between rivers stretches located upstream and downstream of {T}eotonio waterfall and, to a less extent, {J}irau waterfall, independently of the hydrological period. {A}fter accounting for the relative roles of local and regional factors in explaining fish compositional dissimilarity, we still observe a significant effect of the waterfalls. {W}e conclude that these waterfalls act as natural ecological barriers limiting fish dispersal processes and discuss aspects of these ecological filters and the potential effects of two dams currently under construction in the {M}adeira {R}iver.},
