“…Here, however, seasonal differences were mainly driven by an invertebrate species, the polychaete Sabellaria alveolata, which was more abundant in winter than in summer. This species is responsible for the construction of the largest biogenic reefs in Europe, providing a highly dynamic habitat for diversified associated organisms (Dubois et al 2002, Fournier et al 2010. Sabellaria alveolata reefs were indicated as extremely sensitive to the mechanical impact of natural (e.g.…”

SUMMARY:We investigated the seasonal (winter vs summer and within season) and spatial (between-pool) variability of benthic assemblages of rock pools at mid-intertidal level along the shore of Viana do Castelo (North Portugal). Physical traits of rock pools, including size, depth and position along the shore, were also compared between pools. While pools did not differ for any of the examined physical traits, results indicated a clear seasonal difference in the structure of assemblages, including a total of 49 macroalgal and 13 animal taxa. This finding was driven by six taxa that are more abundant in winter (the reefforming polychaete Sabellaria alveolata, the articulated coralline algae Corallina spp., the brown alga Bifurcaria bifurcata, the encrusting coralline alga Lithophyllum incrustans, the red alga Chondracanthus acicularis and the grazing snails Gibbula spp.) and four algal taxa that are more abundant in summer (the invasive brown Sargassum muticum, the green Ulva spp., the kelp Laminaria ochroleuca and the filamentous red Ceramium spp.). These data provide a new contribution to the knowledge of rock pool systems and have potential implications for monitoring programmes aimed at assessing ecological modifications related to natural and anthropogenic disturbances and for identifying processes responsible for the variability of rock pool assemblages.Keywords: rock pools, rocky intertidal, seasonal variability, benthos, Sabellaria alveolata, Portugal. RESUMEN: Comunidades bentónicas de charcas rocosas del norte de Portugal: variabilidad estacional y entre charcas. -Investigamos la variabilidad estacional (invierno vs verano y entre estaciones) y espacial (entre charcas) de las comunidades bentónicas en charcas rocosas del nivel intermareal medio a lo largo de la costa de Viana do Castelo (Norte de Portugal). Además comparamos los parámetros físicos entre las charcas, incluyendo el tamaño, temperatura y posición a lo largo de la costa. Mientras que las charcas no difieren para ninguno de los parámetros físicos examinados, los resultados indican una clara diferencia estacional en la estructura de las comunidades, las cuales incluyen un total de 49 taxones de algas y 13 de animales. Estos resultados fueron inducidos por seis taxones más abundantes en invierno (el poliqueto formador de arrecifes Sabellaria alveolata, el alga coralinal articulada Corallina spp., el alga parda Bifurcaria bifurcata, el alga coralinal incrustante Litophyllum incrustans, el alga roja Chondracanthus acicularis y los caracoles ramoneadores Gibbula spp.) y cuatro taxones de algas más abundantes en verano (el alga parda invasiva Sargassum muticum, el alga verde Ulva spp., el quelpo Laminaria ochroleuca y el alga roja filamentosa Ceramium spp.). Estos datos contribuyen al conocimiento de las comunidades de charcas rocosas intermareales y tienen potenciales implicaciones en los programas de monitorización enfocados a medir las modificaciones ecológicas relacionadas con alteraciones naturales y antropogénicas y son útiles para identifica...

Fournier et al (2010) examined the inter-and intraspecific variability on chemical composition of biocement among sand-reef-building polychaetes, including Brazil- ian populations previously recorded as P. caudata or P. lapidosa Kinberg 1867 from the following states: Santa Catarina, Paraná, São Paulo, Rio de Janeiro, Paraíba, Rio Grande do Norte and Ceará. These authors concluded that there is some degree of variation on the cement's biochemistry among populations.…”

We report the first occurrence of Phragmatopoma caudata Krøyer in Mörch, 1863 in Piauí state, Brazil. This is the first record of this species in the APA Delta do Parnaíba, a national environmental protection area that comprises areas from 3 Brazilian states, Maranhão, Piauí and Ceará. This is also the northernmost and westernmost record of this species in Brazil to date, further extending by 415 km its known distribution in Brazil, and helping to fill a gap on the knowledge of its distribution in South America.

“…Two species have attracted most of the attention in terms of tube building: Sabellaria alveolata and Phrag matopoma californica. The former was investigated mainly in terms of tube structure, building organ morphology, and cement elemental analysis (Vovelle, 1965;Gruet et al, 1987;Fournier et al, 2010); the latter was described in terms of building organ morphology and micro-and nano structure as well as composition of the cement (Stewart et al, 2004;Zhao et al, 2005;Stevens et al, 2007;Wang et al, 2010;Wang and Stewart, 2012). Among sabellariids, P. californica is the only species in which cement proteins have been characterized.…”

Abstract.The shelter of the tube-dwelling polychaete Sabellaria alveolata is composed of mineral particles as sembled with spots of a proteinaceous cement. The adhesive proteins constituting the cement were identified on the basis of their sequence similarity with proteins of a phylogenetically related species, Phragmatopoma californica. Two positively charged proteins, Sa-1 and Sa-2, share coimnon features: they both have a mass of 22 kDa; are rich in glycine, tyrosine and basic residues; and show repeated peptide motifs. The consensus repeat of Sa-1 is KGAY-GAKGLGYGNKAGYGAYG (occurring 6 -8 tunes), while Sa-2 displays the consensus heptapeptide VHKAAWG (5 tunes) and undecapeptide VHKAAGYGGYG (8 times). Two variants of a serine-rich protein, Sa-3A (22 kDa) and Sa-3B (21 kDa), were also identified. Their serine residues account for 75 mol% and are probably phosphorylated, meaning that Sa-3 is very acidic and negatively charged. Moreover, tyrosine residues of all adhesive proteins are presumably modified into DOPA. Although protein se quences are not well-conserved between S. alveolata and P. californica, their main characteristics (including amino acid composition, post-translational modifications, repeated pat terns, isoelectric point, and mass) are shared by both spe cies. This suggests that these features are more important for their function than the primary structure of the proteins. The mRNA abundance for each protein was esthnated by quan titative real-thne PCR, revealing relative expression levels
