MACROINVERTEBRATES AS BIOINDICATORS OF WATER RESOURCES

Abstract

This research focuses on evaluating the usefulness of aquatic macroinvertebrates as
bioindicators for detecting changes in water quality associated with anthropogenic disturbances, as well as understanding the influence of biotic and abiotic factors on their communities. The potential of indices based on the presence or absence of these organisms for low-cost biomonitoring will be highlighted, emphasizing the need to expand their application in regions with limited knowledge such as Venezuela. This work focused on the review of the most recent literature to support the application of macroinvertebrates as bioindicators both nationally and internationally and to point out the lack of information in the area. It will also address the different methodologies applied in the studies, the explanation and usefulness of these biotic indices to reflect tolerance to disturbance, the limitations and challenges that the use of macroinvertebrates as bioindicators addresses.
