Análisis de la calidad del agua del humedal Jaboque mediante la identificación de la comunidad fitoplanctónica y las condiciones fisicoquímicas del agua

Abstract

The general objective of this study was to analyze the water quality of the Jaboque wetland by identifying the phytoplankton community and the physicochemical conditions of the water in two climatic periods, for this the wetland was visited and three sampling stations were located in the three thirds that divides the wetland (high third, middle third and low third at the river mouth of the wetland to the Bogotá river).

For this, phytoplankton samples were taken with a 23 micron mesh and the physicochemical parameters were measured in the field of dissolved oxygen, pH, total dissolved solids, turbidity, conductivity and temperature; The phytoplankton samples were analyzed in the laboratory of the Santo Tomas University and the methodology used for the taxon count was direct and was recorded in a spreadsheet. There were found the diversity indeces of Simpson, Shannon, Margaleft, Menhinick and Berger Parker, to relate the indices to the physicochemical parameters, the genres found were also related to the parameters to see the affinity between these two.

53 genera of phytoplankton were found and the morphotypes that were present in almost all the stations were Navicula Sp., Nitzschia Sp., Mycrocystis sp. and Oscillatoria sp. Indicators of waters with intense and very intense organic pollution.

Due to its importance within the main ecological structure of Bogotá and as an important RAMSAR wetland, the Jaboque wetland needs to be studied and have a tracing on the quality of the water and the ecosystem because there are infrastructure works in progress that affects the ecosystem
