The development of multimetric indices (MMIs) to measure the biotic condition of aquatic habitats is based on metrics derived from biological assemblages. Considering fish assemblages, the inconsistencies in metrics responses outside of the places where they were developed limit MMI transferability and applicability to other locations, requiring local calibration. The factors behind the low transferability of these MMIs are still poorly understood.

Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data.

- The study investigates how environmental factors and human impacts influence the distribution of fish communities in the Upper Paraná ecoregion in South America.
- Researchers analyzed data from 586 fish sampling points, focusing on local beta diversity and alpha diversity, and found high beta diversity overall, with richer fish communities found more centrally in the ecoregion.
- Key findings highlight that both environmental filters and dispersal limitations significantly shape fish assemblages, emphasizing the necessity of using multiple predictors to understand biodiversity better.
