Biodiversity and water quality along the ravine Sambache located in the refuge were determined of Pasochoa wild life in Uyumbicho - Pichincha, through a sampling of five points where samples for physical, biological, and chemical analyses were taken. They were used for the calculation of the ICA index values of pH, temperature (°C), conductivity (mS), turbidity (NTU), total solids (mg/L), dissolved oxygen (mg/l), nitrates (mg/l) and total phosphate (mg/l), and for the ABI index macroinvertebrates. The Shannon index found a diversity of macroinvertebrates, richness and abundance of the PMM-05 point obtained the greater amount of families (27) and individuals (2766). The index of Jaccard indicates that there is an 86.6% of similarity of families between them points PMM-04 and PMM-05. Various of bad to good hydromorphological quality. A total of 11 orders and 38 families of Macroinvertebrates were identified, the most representative were Elmidae (33,49%), leather (17,68%) and Leptoceridae (17,42% with respect to the total number of individuals); less representative families are below eight percent. The ABI value was 54 to 165 representing a very good water quality, while the ICA obtained values of 67,1 to 71,1 with a good average quality, the correlation between the two indices is of 66,2%. |
