Several biotic indices have been proposed for the assessment of the ecological status of benthic macroinvertebrates in marine waters, although none have been generally accepted. When it comes to assessing highly stressed natural environments, such as estuaries, the controversy and uncertainty is much higher than for any given normal index. In this article, we test the behavior and suitability of different biotic indices proposed under the perspective of the Water Framework Directive (S, H, AMBI, M-AMBI, BQI, W-statistic, Taxonomic distinctness) for the assessment of estuaries in northern Spain. The low species richness and dominance of a few tolerant species in the characteristic community of these estuaries presented a challenge to the application of the biotic indices tested. Combined approaches that integrate different aspects of water quality and ecosystem functionality could increase the reliability of the ecological assessment of these transitional waters.
尽管尚未得到普遍认可，但已经提出了几种生物指数来评估海水中底栖大型无脊椎动物的生态状况。在评估诸如河口等压力极大的自然环境时，争议和不确定性比任何给定的正常指数都要高得多。在本文中，我们从《水框架指令》（S、H、AMBI、M-AMBI、BQI、W统计量、分类学差异性）的角度测试了不同生物指数在评估西班牙北部河口时的表现和适用性。这些河口特征群落中物种丰富度低以及少数耐污物种占主导地位，给所测试生物指数的应用带来了挑战。整合水质和生态系统功能不同方面的综合方法可以提高对这些过渡水域生态评估的可靠性。
