This work evaluates four indices that have been used for benthic macroinvertebrate ecological quality classification in the Mediterranean Sea. Our study was based on the data obtained from the participation of Greece and Cyprus in the Mediterranean Geographical Intercalibration group. The indices AMBI, M-AMBI, MEDOCC and BENTIX were applied to the available benthic species data, and the succession of the ecological groups along the graded values of each index was plotted. The level of agreement among methods was calculated, and the performance of each method in estimating ecological quality status was evaluated. AMBI, based on the Atlantic model, and its derivative M-AMBI overestimated the statuses, while MEDOCC showed the best level of agreement with BENTIX. BENTIX gives equal weight to tolerant and opportunistic species groups, which correlates them more closely than the other indices and makes BENTIX the most sensitive in detecting ecological disturbances in the Eastern Mediterranean basin, where tolerant and opportunistic groups seem to play an equally important role in the response of benthic communities to stressors.
本研究评估了地中海地区用于底栖大型无脊椎动物生态质量分类的四个指标。我们的研究基于希腊和塞浦路斯参与地中海地理校准组所获得的数据。应用 AMBI、M-AMBI、MEDOCC 和 BENTIX 指数对可用的底栖物种数据进行分析，并绘制每个指数的分级值沿生态群的演替。计算了方法之间的一致性水平，并评估了每种方法在估计生态质量状况方面的性能。基于大西洋模型的 AMBI 和其衍生的 M-AMBI 高估了状态，而 MEDOCC 与 BENTIX 的一致性水平最高。BENTIX 平等对待耐受和机会主义物种群，这使得它们比其他指数更紧密地相关，并且使 BENTIX 在检测东地中海盆地生态干扰方面更敏感，在该地区，耐受和机会主义物种群在底栖群落对胁迫的反应中似乎发挥着同样重要的作用。
