Caracterización de la calidad del agua de la Quebrada Los Cáquezas, mediante la utilización de macro invertebrados acuáticos

Abstract

Was carried out the characterization of the brook Los Cáquezas was conducted from 2970 to 3174 msnm; It is located in the rural settlement of Los Soches, in Usme, Bogota; using aquatic macroinvertebrates. Sampling was conducted between the months of February and March 2015, three sampling points were selected; the first (E1) at a height of 3174 msnm, where no anthropogenic pollution; the second point (E2) to 3139 msnm and the third point (E3) to 2970 msnm, where has high anthropic intervention. The results of the abundances of the different taxones founds, they were analyzed through BMWP (Biological Monitoring Working Party) adapted to the Savannah of Bogota and other biological indices alpha and beta. Also with the aim to contrast the biological results with the physicochemical parameters was made analysis of statistical correlations (Pearson and Spearman). As results, was found a dominance of some families to E3, while the ecosystems of the E1 and E2 stations were aimed at biodiversity values.
