“…5) according to sampling site rather than algal association, which suggests that some other site-specific factors influence the diversification of mollusc assemblages in synergy with the presence of canopy-forming algal species. As already observed by other authors (Sánchez-Moyano et al, 2000;Gozler et al, 2010), the same sub-association exposed to different hydrographical conditions hosts different invertebrate assemblages. These factors may act indirectly, influencing macroalgal growth and development, or may have a direct effect on mollusc assemblages.…”

“…The dominant and most frequent bivalves, such as Modiolus barbatus and Musculus costulatus, were also reported by other authors in similar algal stands (Poulicek, 1985;Vio & De Min, 1996, Sánchez-Moyano et al, 2000Chemello & Milazzo, 2002;. They are mostly sessile species, living on hard bottoms among holdfasts of macroalgae or attached to the algae themselves (Hrs-Brenko & Legac, 2006).…”

“…The most frequent and top dominant mollusc species found inhabiting Cystoseira associations, the gastropods Jujubinus exasperatus, Rissoa guerinii and Bittium reticulatum, have previously been reported in similar macroalgal associations in different parts of Mediterranean Sea (Poulicek, 1985;Vio & De Min, 1996;Sánchez-Moyano et al, 2000;Chemello & Milazzo, 2002;. These are micrograzer-detritivore species, feeding preferentially on diatoms and epiphyte microalgae, as well as food trapped in sediments retained by algal thalli (Paine, 1984;Ávila, 2003).…”

“…Specifically, low diversity at site MBP was due to a clear dominance of a few species, especially of genus Bittium. These species are generally dominant and frequent in photophilic assemblages elsewhere in the Mediterranean Sea (Poulicek, 1985;Vio & De Min, 1996;Sánchez-Moyano et al, 2000;Chemello & Milazzo, 2002), but such a high abundance, as found at site MBP, is unusual. According to , thalli with complex and branching shape offer suitable conditions for the trophic demands of these grazer/detritivore species, trapping a large amount of organic material.…”

Mollusc assemblages associated with Cystoseira associations were sampled in the southern part of the Gulf of Trieste during the summers of 2008 and 2012. Samples were collected by SCUBA diving in the infralittoral belt (from 1 to 4 m depth). The surface within frames of 20 x 20 cm was scraped off with samples were collected by hand or with an air-lift sampler. Four erected algal species were found: Cystoseira barbata, C. compressa, C. corniculata and Halopithys incurva. A total of 69 species of molluscs were identified in those associations. Gastropoda were dominant, with the highest species richness and abundance, followed by Bivalvia and Polyplacophora. A large number of juveniles were found, proving the importance of Cystoseira associations for mollusc recruitment. Differences in composition, structure and abundance of mollusc assemblages were found for sites dominated by different algal species, and correspond to different morphology and degree of development of canopy-forming species. The present study confirms that the dominant algal species within Cystoseira associations strongly influence, although at different levels, abundance and distribution of mollusc assemblages in the Northern Adriatic Sea.

“…It is an important industrial area, with chemical factories, refineries, thermal power plants, iron works, paper mills and ship yards, along with a major port (Conradi et al, 1997). Recently, several studies have been conducted in Algeciras Bay using subtidal benthic communities as bioindicators (sponges: Carballo et al, 1996;ascidians: Naranjo et al, 1996; epifauna of algae and briozoa: Conradi et al, 1997, Sánchez-Moyano andGarcía-Gómez, 1998;Sánchez-Moyano et al, 2000a, b, 2002. These studies reflected clear differences in community composition between external and internal areas of the Algeciras Bay, showing a good correlation between subtidal fauna and environmental conditions.…”

Abstract.A multivariate approach was used to test the value of intertidal communities as a bioindicator of environmental conditions at Algeciras Bay, southern Spain. The study area is located in the Strait of Gibraltar and it is subjected to a variety of anthropic impacts. Eight localities (5 inside and 3 outside the bay) were selected, and four transects were undertaken in each locality to characterise the fauna and flora. The spatial distribution of the intertidal species reflected the physico-chemical conditions of Algeciras Bay. The stations located outside the bay, characterised by high hydrodynamism and dissolved oxygen and low sedimentation and turbidity, had a higher diversity and species richness than the inner stations. According to the BIO-ENV procedure and CCA, water turbidity was the factor which best correlated with the intertidal assemblages. SIMPER showed that the molluscs Chtamalus stellatus, Mytilus cf edulis, Littorina neritoides and Balanus perforatus, and the algae Gelidium pusillum, Corallina elongata, Asparagopsis armata, Colpomenia sinuosa and Fucus spiralis were the species that most contributed to the dissimilarity between internal and external sites. The present study, based on the spatial distribution of intertidal taxa, yielded similar results to those previously obtained in the area with costly physico-chemical analysis based on complex matrices of subtidal epifaunal communities. Consequently, the intertidal sampling method proposed in this study is presented here as a quick, effective alternative strategy, and can be useful in environmental monitoring programs, since these communities are easily accessible and amenable to sample, and the sessile nature of the majority of the species makes future, long-term monitoring relatively simple.

Effect of Sewage Discharge in Spisula subtruncata (da Costa 1778) Populations

Sewage discharge is a common source of pollution in coastal marine waters. Several municipal treatment plants dump treated water in medium to fine sand Spisula subtruncata communities. This bivalve is generally considered a major food source for demersal fishes, and it is important as a dominant species in structuring the macrobenthic community during the spring and summer months. We sampled within five locations affected by sewage discharge along the Castellon coast (northwest Mediterranean Sea) where S. subtruncata (da Costa 1778) is a common bivalve. Van Veen grab samples were obtained for the study of the bivalve population and to characterize the sediment. The sewage discharges studied affect Spisula populations. In the stations near the outfalls, the abundance and the average size of S. subtruncata decreased. However, this effect did not correlate with sediment characteristics, such as granulometry or pH.
