According to the Water Framework Directive (Directive 2000/60/CE), assessment methods for the biological quality element benthic invertebrates must include diversity, abundance and proportion of pollution sensitive/indicator taxa as indicative parameters. By one hand, the use of pollution sensitive/indicator taxa (indicator taxa indices) is criticized due to the lack of a reliable methodology to know the level at which indicator species can be well represented in unaffected communities. By the other hand, it is often remarked in the literature that the response of diversity measures may be biased by several methodological constraints. In the last few years, several multimetrics, combining both...

The implementation of the European Water Framework Directive has enhanced the development of several indices based on benthic invertebrate communities. Some of them, such as BOPA, simplify the calculation employing the taxonomic sufficiency principle to assess the ecological status of ecosystems since they only consider opportunistic polychaetes and amphipods; others, such as MEDOCC, include all the species found in the community, and assign them to four ecological groups: sensitive, indifferent, tolerant, and opportunistic. Anyway, there is the need for testing, validating and improving these indices in different regions and communities. In this study we test the application of MEDOCC and...

Heretofore, the hesionid polychaete Parasyllidea humesi was only known from its original description, living in association with the bivalve Tellina nymphalis in mangrove swamps north of Pointe-Noire (Republic of Congo, West Africa). The discovery of a stable population in Río San Pedro (Gulf of Cádiz, southern Atlantic coast of Iberian Peninsula) thus represents the second report for this species worldwide, and the first for European waters. Furthermore, the new population is associated with another bivalve, Scrobicularia plana. The host-symbiont relationship is characterized by a high host-specificity (the symbiont was absent from Ruditapes decussatus and Cerastoderma glaucum collected in the same...
