SUMMARY:

The increase in anthropic activities causes several long-term problems within an ecosystem, including the introduction of species, mainly in the fish community, making the river-estuary systems, which are rich, and diverse and have a high rate of endemism and high productivity suffer gradual consequences. Non-native species have new and/or redundant functional characteristics and may contribute to modifying the structure and functionality of an ecosystem, impacting ecological processes and functionally homogenizing the native community. Our results inferred that this impact is differentiated in each component of functional diversity, and evidenced by the withdrawal scenarios of non-native species, observing a significant decrease in functional richness (FRic) in the Depression region and an increase in functional dispersion (FDis) in the Tableland region. It can also be observed that non-native species are appearing in the region considered estuarine in the lower São Francisco River (Lowland), where even though it is a region with a high rate of functional redundancy, with the appearance of non-native species, it is not known for sure what would happen in this region with these new functional characteristics in the ecosystem.
