Abstract

This study examined the composition and diversity of the invertebrate communities that inhabit the hyporheic zone (HZ) in the upper and lower basins of the Dagua River, a tropical mountain stream, and their relationship with the macrobenthic fauna. In the HZ, different taxa were collected, many of which have been reported in several regions worldwide, suggesting that the biodiversity of the hyporheic community in Colombian rivers may be high. Although the hyporheic and macrobenthic fauna shared a moderate percentage (> 50 %) of taxa, their ecological structures were different. The analysis of hyporheic filtrate water showed the presence of microplastic (MP) fibers as well as fauna, a condition that, based on the literature review, could represent a risk for the normal functioning of this river ecosystem.

哥伦比亚一条新热带山地河流中底栖动物和大型底栖动物的组成和分布

本文研究了热带山川大瓜河上下游盆地潜流带(HZ)无脊椎动物群落的组成、多样性及其与大型底栖动物的关系。在哥伦比亚河流中，收集到不同的分类群，其中许多分类群已在世界多个地区报道，表明哥伦比亚河流中隐流群落的生物多样性可能很高。深底栖动物与大型底栖动物的类群比例中等(50% ~ 50%)，但生态结构不同。对低渗滤液的分析显示，微塑料(MP)纤维和动物的存在，根据文献综述，这种情况可能对河流生态系统的正常功能构成威胁。
