Validation of an index of biological integrity based on aquatic macroinvertebrates assemblages in two subtropical basins of central Mexico

ABSTRACT: The increasing degradation of freshwater ecosystems has demanded the development of methods that allow us to evaluate the ecosystem alterations. The Indexes of Biological Integrity (IBI) are a methodological approach to assess the condition of aquatic ecosystems. The objective of this stud...

The Indexes of Biological Integrity (IBI) are a methodological approach to assess the condition of aquatic ecosystems. The objective of this study was to estimate the biological integrity and to validate the Index of Biological Integrity based on macroinvertebrate assemblages (IIBAMA) in 33 study sites rivers in the Lerma-Chapala and Pánuco river basins, in central Mexico. The Family-Level Biotic Index (FBI) was used to estimate the water quality and the Visual-Based Habitat Assessment (VBHA) was used to estimate the habitat quality. Spearman correlation analysis among IIBAMA, FBI, VBHA and water characteristics were made for validation of the IIBAMA. Besides, all variables were evaluated together by multivariate analyses. The rivers were classified in three of four biotic integrity categories, poor, regular and good, being poor the most common (88% of the study sites). We did not find study sites with excellent biotic integrity. The rivers of the Lerma-Chapala River Basin showed a worse ecological condition compare with the Pánuco Rivers Basin. We validated and recommended the using of the IIBAMA to assess the biological integrity of these two basins and rivers in central Mexico. This research represents the first efforts to validate an IBI based on aquatic invertebrate communities in a broad scale in Mexico and provide a general framework for their widespread use and to approach the validation and implementation of IBIs in other regions with similar conditions.info:eu-repo/semantics/openAccessPontificia Universidad Católica de Valparaíso.
