The main aim of this study was to improve the knowledge about the concordance among macrophytes and macroinvertebrates to provide complementary information and facilitate the procedures for quality assessment of river ecosystems. Macrophytes and macroinvertebrates were collected in 11 sampling sites along a central Apennine calcareous river in October 2008 and June 2009. The concordance between the two biomonitoring groups was tested according to several environmental parameters. The comparison of data matrix similarities by Mantel test showed differences in the assemblage of macrophytes and macroinvertebrates along the river since correlation values were 0.04, p > 0.05 in October 2008 and 0.39, p > 0.05 in June 2009. The study revealed lack of concordance between the two groups, emphasizing that the information provided by macrophytes and macroinvertebrates does not overlap in terms of response to environmental parameters. Indeed, the two different biological groups resulted useful descriptors of different parameters. Together, they could represent a complementary tool to reflect the river environmental quality.
本研究的主要目的是增进对大型植物和大型无脊椎动物之间一致性的了解，以提供补充信息，并促进河流生态系统质量评估程序。2008年10月和2009年6月，在亚平宁山脉中部一条钙质河流沿线的11个采样点采集了大型植物和大型无脊椎动物。根据若干环境参数对这两个生物监测组之间的一致性进行了测试。通过Mantel检验对数据矩阵相似性进行比较，结果表明，2008年10月大型植物和大型无脊椎动物的组合存在差异，相关值为0.04，p>0.05；2009年6月相关值为0.39，p>0.05。该研究揭示了这两组之间缺乏一致性，强调大型植物和大型无脊椎动物提供的信息在对环境参数的响应方面并不重叠。事实上，这两个不同的生物组是不同参数的有效描述指标。它们共同构成了一个反映河流环境质量的补充工具。
