Abstract EN
This study was aimed at determining the performance of some indices and community attributes frequently used to assess river quality and test the role of macroinvertebrate taxa richness as element of bioindication in several coastal tropical streams of western Esmeraldas (Ecuador).
In addition, a macroinvertebrate taxon list of this region was provided for the first time.
Thirteen sampled points distributed across nine streams were selected for this study and nineteen parameters and attributes of bioindication were tested.
The differences between nonimpact and impact places were evaluated mainly using one-way analysis of variance.
Jackknife 2 and Clench were used to estimate the regional richness and the quality of the inventory, respectively.
Seventy taxa (principally genus and family) of the main groups of macroinvertebrates were collected.
Measured richness and family richness were the best metric followed by Biological Monitoring Working Party/Colombia (BMWP/Col), Odonata richness, Shannon-Weiner, and EPT richness (Ephemeroptera + Plecoptera + Trichoptera) indices.
Only a slight right trend (Ephemeroptera, Trichoptera, and Chironomidae attributes) or incorrect performances (Average Score Per Taxon (ASPT) and % EPT) were showed by frequently used metrics.
Finally, several recommendations were made about taxonomic level used, the ranks of quality of taxa richness, and the effort-results relationship in the field of bioindication.
