Abstract Bioindication is a method to assess environmental conditions using indicator organisms. In Colombia, water quality evaluation is mostly performed following the Biological Monitoring Working Party/Colombia method (BMWP/ Col), which uses aquatic macroinvertebrates at the taxonomic family level. Studies on potential bioindicators are important to produce comprehensive information on the requirements of macroinvertebrates and their value for water quality bioindication. We studied the larval ecology of several common genera of Odonata from Colombian freshwater ecosystems and assigned an indicator value to each genus.The physical and chemical water characteristics of 1,022 sites surveyed in Colombia from 2005 to 2016 were analyzed using a principal component analysis (PCA). The relationship between environmental conditions and Odonata genera found was studied using multiple logistic regressions between sample coordinates of the first three axes of the PCA and occurrence of the respective genus. We assigned an indicator value for each genus using the logistic regression and the water quality of samples. The highest indicator values were assigned to genera, which were mainly explained by the PCA axis associated with water quality, showed a high odds ratio to this axis, and were found in ecosystems with excellent water quality.The indicator values suggested for each taxon are, Brechmorhoga Kirby, 1894, 8; Macrothemis Hagen, 1868, 4; Micrathyria Kirby, 1889, 4 (Libellulidae); Progomphus Selys, 1854, 7 (Gomphidae); Acanthagrion Selys, 1876, 4; and Argia Rambur, 1842, 7 (Coenagrionidae). Differences in water quality preferences in genera of the same family suggest that higher taxonomic resolution may allow more detailed environmental assessments.

哥伦比亚蜻蜓属部分幼虫的生态学及指标值探讨

摘要 生物指示是一种利用指示生物评估环境条件的方法。在哥伦比亚，水质评估主要按照生物监测工作组/哥伦比亚方法 (BMWP/Col) 进行，该方法在分类科级别使用水生大型无脊椎动物。对潜在生物指标的研究对于生成关于大型无脊椎动物的要求及其对水质生物指标的价值的综合信息非常重要。我们研究了哥伦比亚淡水生态系统中几个常见的蜻蜓属的幼虫生态，并为每个属分配了一个指标值。 使用主成分分析 (PCA) 分析了 2005 年至 2016 年哥伦比亚调查的 1,022 个地点的物理和化学水特征. 使用 PCA 前三个轴的样本坐标与相应属的出现之间的多重逻辑回归来研究环境条件与发现的 Odonata 属之间的关系。我们使用逻辑回归和样品的水质为每个属分配了一个指标值。最高的指标值被分配给属，主要由与水质相关的 PCA 轴解释，与该轴显示出高优势比，并且在水质优良的生态系统中被发现。为每个分类单元建议的指标值是， Brechmorhoga Kirby, 1894, 8; 马克西米斯·哈根，1868 年，4；Micrathyria Kirby, 1889, 4 (Libellulidae); Progomphus Selys, 1854, 7 (Gomphidae)；Acanthagrion Selys, 1876, 4; 和 Argia Rambur, 1842, 7 (Coenagrionidae)。
