“…In comparison with some of the main studies conducted in Brazil on the malacofauna associated with macroalgae (e.g. Jacobucci et al, 2006;Lacerda et al, 2009;Leite et al, 2009), the present study found the greatest number of species.…”

“…Jacobucci et al, 2006;Lacerda et al, 2009;Leite et al, 2009), Bittiolum varium, columbellids and pyramidellids, for example, represented the most abundant and frequent species, which reinforces even further the importance of macroalgae for many organisms, especially small species. This fauna is composed of species that have an average size of 2 to 3 mm and represent a great challenge in the detection and identification of specimens, which are therefore often underestimated in faunistic surveys.…”

“…According to the studies of other macroalgae of foliaceous or laminar appearance (e.g. Jacobucci et al, 2006;Lacerda et al, 2009;Leite et al, 2009), there is a predominance of bivalves. However, in the two species of macroalgae collected in Tubarão River, there was a predominance of gastropods, with the largest quantity of bivalves being found only in G. cuneata.…”

The fronds of marine macroalgae play an important role in coastal ecosystems because the algae banks are utilized as a microhabitat by different taxa, including molluscs, one of the most abundant and diverse animals of marine ecosystems. In this study, we characterized the malacofauna associated with the macroalgae Gracilaria domingensis (Kützing) Sonder ex Dickie 1874 and Gracilaria cuneata Areschoug 1854 of a hypersaline mangrove on the northern coast of the state of Rio Grande do Norte, Northeastern Brazil. The first alga dominates in the rainy season and it is substituted by second one in the dry period. A total of 1,490 molluscs were surveyed, representing 56 species in 29 families: 1,081 were associated with G. domingensis and 409 with G. cuneata, the latter showing the greater diversity (H'=1.25). Columbellidae, Neritidae, Pyramidellidae and Cerithiidae were among the most representative families in the number of species and individuals. The micromolluscs were dominant in the algal microhabitat, constituting 74.63% of the malacofauna recorded. The columbellid Parvanachis obesa (C. B. Adams, 1845) was the dominant species followed by the neritid Neritina virginea (Linnaeus, 1758) in both algae. In spite of the annual alternated succession of the algae species, at least 15 mollusc species are common for these algae. Furthermore, juveniles of P. obesa were recorded in both seasons, indicating a continuous reproduction. Possible reasons for difference in abundance, diversity and dominance of molluscs living on these algae are discussed. Both species of substrate-algae represent an important microhabitat for refuge, feeding and the reproduction of small-sized mollusc species during rainy and dry seasons.Keywords: mollusc diversity, inventory, semiarid littoral, Ponta do Tubarão, Parvanachis obesa.

“…Porém, fatores físicos como temperatura, radiação solar e variação de marés podem interferir na distribuição e/ou diversidade das espécies no substrato (ABSHER, 1982;NYBAKKEN,1997;SCROSATI & HEAVEN, 2007). Dentre os invertebrados, os bivalves e gastrópodes podem ser considerados como grupos abundantes em substratos rochosos de região entremarés (ABSHER, 1982;LACERDA et al, 2009). Entretanto, em relação aos gastrópodes, a maior mobilidade e as diferentes formas de alimentação (LEITE et al, 2011) os diferem dos demais moluscos que ocorrem nestas regiões, além de serem utilizados como indicadores de contaminação ambiental e das diferentes faixas dos costões rochosos (BAUER et al, 1995, LEITE et al, 2011, CASTRO et al, 2012.…”

O objetivo deste trabalho é caracterizar a distribuição dos gastrópodes na desembocadura do Complexo Estuarino de Paranaguá. Foram realizadas em um costão rochoso da Ilha do Mel oito coletas mensais, durante dois períodos (julho a outubro de 2010; janeiro a abril de 2011), em três níveis (Superior, Médio e Inferior), com três réplicas. Os parâmetros ambientais foram avaliados in situ (temperatura do ar, da água e salinidade). Observou-se a presença de Lottia subrugosa, Litorina flava, Litorina sp., Stramonita brasiliensis e Onchidella indolens. A distribuição dos gastrópodes foi caracterizada como tendo predominante L. subrugosa no nível Inferior, Litorina sp. no nível Médio e L. flava no nível Superior. Pode-se constatar que as espécies de gastrópodes de um costão rochoso na desembocadura do Complexo Estuarino de Paranaguá estão mais relacionadas com a capacidade de cada espécie em suportar dessecação, alimentação e agregações para reprodução do que as variáveis ambientais avaliadas.

“…Os gastrópodes podem ser considerados como um dos grupos mais abundantes da malacofauna presentes em substratos rochosos de região entremarés, (ABSHER, 1982;LACERDA et al, 2009). Dentre as espécies de gastrópodes que constituem a malacofauna da costa sul do litoral brasileiro, destacam-se as espécies de arqueogastropodes Fissurella clenchi e Lottia subrugosa (RIOS, 2009;ROSENBERG, 2013).…”

The reproductive period of the gastropod L. subrugosa was investigated through monthly samples from July to October of 2010 and January to April of 2011. The specimens were collected from intertidal rocky coast of Ilha do Mel, Paraná, Brazil (25° 33' 47,6" S; 48° 19' 05,8" W), in three levels (high, mean and low), with three replicates. Ten individuals were collected monthly. Data on air and seawater temperature and salinity were also obtained. Results indicated individual with mean height 4.09 mm and 11.40 mm in length, sexual proportion of 2.64:1 (58 males: 22 females). A reproductive behavior characterized by grouping in certain months coincident with a decrease of full and partially full gonads was observed.
