Informe de Investigación "Composición y abundancia de macroinvertebrados acuáticos en el río Acacias departamento del Meta, Colombia."

Abstract

Benthic macroinvertebrates are important within aquatic ecosystems because they intervene in the transfer of energy in trophic networks, being an important resource for continental fish communities. Measurements of physicochemical variables were carried out in situ, the individuals were collected by means of surber networks, later they were conserved in alcohol for their identification to the lowest possible taxonomic level. A total of 278 individuals represented in 10 families were collected, of which Leptophlebiidae and Perlidae stand out, 17 genera were identified, the most important being Farrodes, Anacroneuria, Americabaetis and Camelobaetidius. The registered genera are common in ecosystems of the plains foothills, these ecosystems characterized by their clear waters and oligotrophic conditions, show favorable conditions for these communities in the composition of macroinvertebrate fauna.
