“…Only the gastropods Columbella mercatoria, Eulithidium affine and E. bellum were common to both studies. On the other hand, Cunha et al (2013) found a composition of bivalves (composed of condylocardiids, crassatellids and mytilids) and part of the composition of gastropods (composed especially of caecids, columbellids, cylichnids, cystiscids, pyramidellids, scissurellids, vtrinellids and Nudibranchia) very different from the composition reported herein; (4) Luz & Couto (2014) also studied the composition of mollusks from reef ecosystems on the coast of Bahia and found a total of 28 species in the reef environments studied, 11 of which also identified in the present study for Morro de São Paulo. Among all these surveys, the study by Luz & Couto (2014) and the present investigation had the greatest richness of mollusks in areas of the continental shelf of Bahia, which demonstrates the importance of reef ecosystems as highly diversified environments.…”

The reef ecosystems of Morro de São Paulo are located in the Tinharé-Boipeba Environmental Preservation Area which was established in 1992 in the state of Bahia, Brazil. Despite this area has been created more than two decades ago, no study has provided knowledge on the invertebrate biodiversity associated with such reef ecosystems. The present investigation provides the first inventory of benthic mollusks associated with the reef ecosystems of Morro de São Paulo based on the collection of living specimens and fresh empty as well as some worn shells. Mollusks were sampled in January 2015 and August 2016 through intensive searches from the intertidal to shallow subtidal habitats of the reefs on three beaches of Morro de São Paulo. Taxonomic richness and biodiversity indices were analyzed. This rapid assessment of the malacofauna resulted in the determination of 84 species belonging to 44 families of gastropods as well as 13 species belonging to eight families of bivalves and one chiton (total: 98 species). Species richness was numerically dominated by members of the subclass Caenogastropoda. The families with the largest number of species were Ranellidae (5), Muricidae (6) and Marginellidae (7). Conus regius, Cypraecassis testiculus, Lobatus goliath, Strombus pugilis, Tonna galea, Turbinella laevigata and Vasum cassiforme are extremely vulnerable macrospecies in the region due to their commercial importance. Comparisons of the malacofauna composition between the study site and Abrolhos Bank were made from data published for this region. ACE and CHAO 1 estimated 133 mollusk species for the region. Despite the rapid assessment, the number of species discovered in the study area approached 73.6% of the estimated total number. The considerable number of mollusk species found in a relatively small area with insufficient sampling underscores the importance of the reef ecosystems of Morro de São Paulo as a one priority area for conservation on the coast of the state of Bahia, Brazil, for which the species richness of other invertebrate groups is virtually unknown.

“…The epifauna was represented mainly by gastropods, crustaceans and polychaetes corresponding closely with communities on European coasts (Cacabelos et al, ; Engelen et al, ; Gestoso et al, ; Guerra‐García et al, ; Sánchez‐Moyano, García‐Adiego, Estacio, & García‐Gómez, ). These are among taxa frequently associated with macroalgal communities (Ba‐Akdah, Satheesh, & Al‐Sofyani, ; Cunha, Güth, Bromberg, & Sumida, ). They constitute substantial prey for many fish species providing an important trophic link between primary producers and higher levels (large predators) in littoral food chains (Wikström, ).…”

The introduction ofSargassum muticummodifies epifaunal patterns in a Moroccan seagrass meadow

et al. 2018

Marine macrophytes sustain valuable epiphytic biodiversity. Nonindigenous macroalgae may induce changes in composition and structure of epifaunal assemblages and therefore support different assemblages from those associated with native species. In this study, differences in faunal community structure between the introduced fucoid Sargassum muticum and the native seagrass Cymodocea nodosa were tested over a year on an intertidal shallow sandy bottom at the southern introduction front, the El Jadida coastline (NW Morocco). Epifaunal community structure consistently differed between macrophytes through seasons, with more species‐rich assemblages associated with S. muticum than C. nodosa despite comparable abundances. The significantly greater epifauna diversity on S. muticum may be related to its structural complexity. However, the species contributing most to differences in assemblages between both macrophytes, such as Steromphala umbilicalis and S. pennanti, were found on both habitats with temporally varying abundances. Some species‐specific affinities were detected (Stenosoma cf. acuminatum, Elasmopus vachoni, Chauvetia brunnea). Nitrogen, dissolved oxygen, suspended matter and temperature were identified as the best explanatory variables contributing to the observed macroepifaunal patterns. This study provides evidence that S. muticum acts as a favourable and additional habitat for epifaunal species and supports a more diverse epifaunal assemblage in this Moroccan seagrass meadow.

“…A principal característica da região é a projeção da plataforma continental, um alargamento que pode chegar a 200 km da linha de costa adiante da cidade de Caravelas, litoral sul da Bahia, diferindo da média de 50 km da largura da plataforma na costa nordeste e leste do Brasil (LEÃO;KIKUCHI, 2001;TEIXEIRA et al, 2013). Localização e batimetria do Banco de Abrolhos, assinalando as principais estruturas sedimentares da região, com ênfase nos recifes de corais.O Banco de Abrolhos é composto por um mosaico de estruturas sedimentares, que englobam recifes de corais -os mais importantes do Atlântico Sul(MOURA et al, 2013), recifes rasos(CUNHA et al, 2013), algas calcáreas, lamas calcíferas e areias(LEÃO, 1982;IBAMA/FUNATURA, 1991). região caracteriza-se por profundidades que raramente excedem os 30 metros, com inclinação de 0°08', podendo alcançar os 70 m na quebra da plataforma(SILVA, 2013).…”
