The objective of this work was to compare different approaches that allow a better characterization of the environmental quality using benthic macroinvertebrates as indicators in rivers of the southwestern highlands. The study was developed with data from the hydrobiology monitoring of the Quellaveco Project between the years 2013-2015, with which we obtained quality indices (ABI, EPT, IMEERA and SVAP), community structure indices (Shannon, Simpson, N1 of the Hill and Pielou series) and functional diversity indices (richness, diversity, dissimilarity and functional equity, and Rao’s Q). The results of the multivariate analyzes showed that the rates of functional diversity, Simpson’s index and IMEERA have significant representativeness in the study units. We concluded that functional diversity indices can be alternative to traditional and environmental quality indices, in addition to characterizing the ecosystem based on the number of species and their abundance in a community, or the functional features they cover, are insufficient to fully explain the quality of an ecosystem.
