Human activities in natural systems promote changes that endanger aquaticcommunities due to the loss of ecological niches, generating a decrease in richness and diversity.The bird and fish assemblages of four wetlands in Pampean streams with peri-urban and ruralland uses in their basins were studied. The results evidenced that there are important differencesin the composition and structure of the assemblages of birds and fish according to the basin ofbelonging. The lowest values of richness and diversity were registered in the peri-urban places,where the dominance of the most tolerant species of both groups of vertebrates was also observed.The simultaneous study of these environments enabled records of how, in the same region,human-induced changes condition the configuration of birds and fish assemblages. Consequently,the analysis multi-taxa performed is not only a diagnostic report but can also be used as a tool formonitoring, developing and implementing remediation measures
