摘要: 1. The assessment of quality status Transitional Aquatic Ecosystems remains a challenge for the ecologists. 2. Here, we compared results two common indices (AMBI - Ecological Groups and BOPA/BO2A -Taxonomic Sufficiency) from samples coming north-eastern Atlantic Mediterranean Sea. Both biotic rely on distinct assessments species sensitivity/tolerance. 3. Six studies provided raw data that permitted AMBI BOPA to be compared. A total 922 element was available, most them Seine estuary (78%). database later divided into three sub-sets: French Waters, Coastal Waters Lagoons. 4. indices' values demonstrated strong correlation; however, index had tendency overestimate EcoQS obtained index, mainly due discrepancies between ‘high’ ‘good’ quality. 5. New thresholds are proposed in order reduce this overestimation.
