摘要

本研究通过描述与大型植物凤眼莲（Pontederiaceae）（也称为Buchón de Agua）相关的水生大型无脊椎动物，评估了Ciénaga La Pachita沼泽（哥伦比亚塞萨尔）的水质。该评估还检查了不同水文时期的物理和化学变量，估计了α和β多样性指数，并确定了BMWP/Col和ASPT水质指数。结果收集到1550种大型无脊椎动物，分属5纲11目21科。阿尔法和贝塔多样性指数显示中等多样性，昆虫纲占主导地位。鞘翅目种类最多，而直翅目数量最多，摇蚊科最占优势。确定的家族中有很大一部分与溶解氧和悬浮固体显著相关。总之，Ciénaga La Pachita具有与凤眼莲根系统相关的大型生物多样性。

Macroinvertebrados asociados a Eichhornia crassipes (Pontederiaceae) en la Ciénaga La Pachita (Cesar, Colombia)

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.
