Abstract
The ecological quality of the Tota River was evaluated during August 2007 and February 2008 and compared to the upper part from Bogotá River between October 2013 and January 2014, by applying the BMWP/Col and ABI indexes. The sampling points corresponding to the high, medium and low part of the longitudinal gradient. In the Tota River, 27 families were determined corresponding to 11 orders, where the most abundant were Baetidae (25.43 %), Leptohyphidae (16.43 %), Naididae (13.76 %), Chironomidae (11.42 %) and Hyalellidae (10.30 %). In the upper course of Bogotá River, 32 families were determined to conform 13 orders, where the most abundant were Chironomidae (28.94 %), Leptoceridae (25.20 %), Naididae (18.34 %) and Simuliidae (8.63 %). In the river Tota, The BMWP/Col. The index showed a good status, while the ABI index exhibited an acceptable quality. On the other hand, in the upper part of the Bogotá River, both the BMWP/Col. and ABI showed variations in quality between acceptable and very critical. The CCA for the Tota River exhibited correlations between temperature and conductivity with the families Hyalellidae and Leptohyphidae while the stream flow was linked with the family Sphaeriidae. On the other hand, in the upper part of Bogotá River the stream flow, conductivity and temperature were correlated with the occurrence of the family Veliidae. Our results showed that the ABI index is more sensitive to impacts that the BMWP/Col index is showing its ability to evaluate the Andean mountain systems.
