“…The identities of specimens from all localities were confirmed taxonomically with the literature (e.g. Domaneschi andMartins 2002, Mikkelsen andBieler 2008). To facilitate further identification of species in future studies, we provide a brief diagnosis with illustrations based on the specimens studied.…”

“…These features may be related to the structure of the oyster habitat, in which dense banks normally have narrow and irregular crevices. According to Domaneschi and Martins (2002), specimens are numerous within crevices and cavities, where they show a pronounced elongation of the valves. Along the beaches of the State of Rio Grande do Norte, and at Japaratinga Beach, State of Alagoas, I. bicolor was observed under rocks and in crevices of intertidal arenitic beach rocks.…”

This study provides the first record of the exotic invasive bivalve Isognomon bicolor for the State of Paraíba, Northeastern Brazil. It has been found to occur in at least twelve coastal reefs along the coast. We also present its first record for the State of Alagoas and new record localities for the States of Rio Grande do Norte and Pernambuco, including its occurrence in hypersaline estuaries. From these records the distribution range of I. bicolor has been expanded to the littoral region of Northeast Brazil, where this invasive species seems well established.

“…No entanto, representantes do gênero Fissurela já foram relatados na região de Santos em associação à alga Amphiroa fragilissima (Masunari 1982). Merece destaque a presença do bivalve Isognomon bicolor, espécie exótica que vem ampliando sua distribuição geográfica no Brasil desde meados da década de 90, invadindo o espaços originalmente colonizados por espécies exploradas comercialmente como ostras e mexilhões (Crassostrea rhizophorae e Perna perna) na região costeira (inclusive infralitoral) em todo o Estado de São Paulo, preocupando as comunidades humanas que dependem destes recursos (Domaneschi & Martins 2002).…”

This work represents the first effort to assess the phytal macrofauna of Queimada Pequena island and was focused in mollusks, crustaceans and echinoderms associated to Sargassum spp. Sampling of the macrofauna was performed by random collections of 6 Sargassum fronds 6 m deep using SCUBA. The fronds were sealed underwater in individual 200 μm mesh bags and detached from the rocky shore. The samples were preserved in recipients in 10% formalin and carried to the laboratory to remove and identify the associated fauna. Forty one taxa were registered, with dominance of peracarid crustaceans. Mollusk composition is different from that of northern São Paulo coast. From the sixteen mollusk species recorded, only the gastropod genera Anachis and Odostomia and the bivalves Musculus and Modiolus were recorded in the Sargassum macrofauna at both coastal regions of São Paulo state, although the genus Fissurela had already been recorded at Santos region associated with the alga Amphiroa fragilissima. The occurrence of the exotic bivalve Isognomon bicolor was also confirmed. Our data suggest differences in the composition of molluskan fauna between southern and northern coasts of the state. Extensive investigations are necessary to confirm these results and to support management strategies in this conservation unit.

“…Relativamente a las demás especies de moluscos, Marquez & Jiménez (2002) (Rios 1994, Muniz et al 2000, Neves et al 2007), mientras Isognomon alatus, considerada una especie exótica invasora del litoral brasileiro (Domaneschi & Martins 2002), anteriormente citada apenas para el Atol das Rocas y de Rio de Janeiro hasta Rio Grande do Sul (Rios 1994, Domaneschi & Martins 2002, Ribeiro et al 2003 es una especie tolerante a las variaciones de salinidad, típicamente encontrada en regiones estuarinas, constituyéndose una de las especies básicas de las comunidades incrustantes encontradas en las raíces de mangles Rhizophora mangle de la región caribeña (Márquez & Jiménez 2002, Romero-Murillo & Polanía 2008. Aunque los briozoos encontrados en el estuario del río Massangana sean comúnmente registrados en ambientes estuarinos (Winston 1977, 1982, Creary 2002, Nolella stipata ya había sido referida para el litoral de Pernambuco (Marcus 1955), pero la ocurrencia de las especies Biflustra savartii, Bowerbankia gracilis y Conopeum reticulum en este estado constituye una ampliación de la distribución geográfica, una vez que ellas ocurrían apenas en los estados del Sudeste y Sur del Brasil, sucediendo lo mismo para Amathia vidovici, presente en el estado vecino de Alagoas (Vieira et al 2008).…”

. 2009. Vertical zonation of the hard substrata macrofauna of the Massangana River estuary, Suape Bay (Pernambuco, Brazil). Biota Neotrop. 9(1): http://www.biotaneotropica. org.br/v9n1/en/abstract?article+bn01609012009. Abstract:The estuarine area of the Massangana River (Pernambuco, Brazil) undergoes several kinds of interventions as a result of the activities of the Suape Industrial and Harbor Complex, which could affect local biotic communities. Thus, this study aimed to verify the composition of the benthic macrofauna of hard substrates regarding their vertical distribution in order to support the future biomonitoring of possible changes in this complex. The invertebrates found in an area of 519 m 2 were collected and their distribution on the biogenic and abiogenic substrates was described. A total of 79 species were found, primarily in the mangroves and distributed in three intertidal zones: a Chthamaletum, which comprised the intertidal and upper shore, the balanid zone, with barnacles and oysters in the mid intertidal, and the Bostrychietum, in the lowest region. In general, this matched the Brazilian and international vertical distribution patterns for mangrove invertebrates. The presence of rocky substrate and the area's high salinity made possible the occurrence of 28 species-including the coral Siderastrea stellata -in an estuarine area. The enlarged distribution of the bivalve Isognomon alatus, the barnacle Amphibalanus reticulatus, and the bryozoans Biflustra savartii, Bowerbankia gracilis, and Conopeum reticulum on the Brazilian coast can be explained by the proximity to the Port of Suape, which allows for passive transportation on ships. The scattered distribution of the fouling organisms among the substrates and the absence of characteristic animals of this ecosystem (such as the mussels) suggest that the environment is already undergoing some stress due to the diverse human interventions occurring in this area. Keywords: spatial distribution, macrobenthos, mangrove, biodiversity, Northeast Brazil. Resumen: El área estuarina del río Massangana (Pernambuco, Brasil) está sujeta a diversas intervenciones antropomórficas resultantes de las actividades del Complejo Industrial y Portuario de Suape, que pueden afectar las comunidades bióticas. Con esa perspectiva, este estudio tuvo como finalidad verificar la composición de la macrofauna bentónica de los sustratos sólidos, en su gradiente de distribución vertical, que sirva de referencia para futuros monitoreos biológicos relacionados a los cambios que pueden ocurrir en el complejo portuario. Se colectaron los invertebrados presentes en un área de 519 m 2 y su distribución en los sustratos biogénicos y abiogénicos es mostrada en el siguiente trabajo. Fueron encontradas 79 especies presentes principalmente en los mangles y distribuidas en tres zonas del intermareal: Chthamaletum, delimitando el supralitoral, "zona balanoide", conteniendo cirripedios y ostras, en la región intermareal media, y el Bostrychietum, en la región inferior. Esta distribución co...
