- Abstract
The present study assesses the water quality of Ciénaga La Pachita swamp (Cesar, Colombia) by characterizing the aquatic macroinvertebrates associated to the macrophyte Eichhornia crassipes (Pontederiaceae), also known as Buchón de Agua. The assessment also examines physical and chemical variables in different hydrological periods, estimates alpha and beta diversity indices, and determines the BMWP/Col and ASPT water quality indices. As a result, 1550 macroinvertebrates are collected, belonging to five classes, 11 orders, and 21 families. Alpha and beta diversity indices show medium diversity and the class Insecta is dominant. The order Coleoptera is the most diverse while the order Diptera is the most abundant, the Chironomidae family being the most dominant. A significant percentage of the families identified are significantly correlated with both dissolved oxygen and suspended solids. In conclusion, the Ciénaga La Pachita has a medium diversity of macroivertebrates associated to the radicular system of E. crassipes.
