“…The water rapidly recovered to normal concentrations, but the sediments still contained typical petroleum hydrocarbon 7 months later (Zanardi et al, 1999b). Migotto et al (1993) argued that the continuous input of contaminants reduced the number of species and the abundance of molluscs in the São Sebastião littoral. The results obtained in stations 7 and 10 (situated near the DTCS terminal) confirmed this trend of lower density values and reduced species number.…”

A Functional Analysis of the Benthic Macrofauna of the São Sebastião Channel (Southeastern Brazil)

2004

The major problem in coastal areas of developing countries is disturbance caused by anthropogenic influence. This disturbance can be quantified by analysing the distribution and composition of marine communities using uni-and multivariate techniques and the biotic index. A study of benthic macrofauna was carried out along the São Sebastião Channel, northern coast of São Paulo State, Brazil, in an area with a submarine outfall, a petroleum terminal and a commercial harbour. Sampling was undertaken seasonally, by means of a van Veen grab (0.1 m 2 ) at 15 oceanographic stations, from November 1993 to August 1994. A total of 392 species were identified (129 Polychaeta, 127 Mollusca, 98 Crustacea, 28 Echinodermata and 10 other phyla). The sedimentary pattern recorded for the São Sebastião Channel is very heterogeneous, influenced mainly by strong wind-driven currents, and differs from nearby shelf areas. The study area could be divided into three regions based on sediment texture and fauna: one region dominated by medium and coarse sand with low values of organic carbon; a second area where pelitic fractions were dominant with high values of organic carbon and nitrogen; and a third region characterised by fine and very fine sand, presenting intermediate organic carbon values. No temporal significant variation in abundance and species composition was found, except in autumn. The use of the Ômarine Biotic CoefficientÕ showed the same ecological trend as the faunal abundance and demonstrated that the central continental region of the channel is affected by human activities.

“…Most species are now restricted to relatively limited geographic ranges and have specialized niches being, therefore, considered a group of rare species (Coan & Valentich‐Scott, ; Harper, Dreyer, & Steiner, ; Harper, Hide, & Morton, ; Morton, ). Species from the families Cuspidariidae, Pandoridae, Periplomatidae and Thraciidae have been recorded from the northern coast of São Paulo state, in southeastern Brazil (Amaral & Nallin, ; Migotto, Tiago, & Magalhães, ; Salvador, Domaneschi, Amaral, Morgado, & Henriques, ; Soares‐Gomes & Pires‐Vanin, ; Tallarico et al, ).…”

Ultrastructure of the spermatozoa of three species of Anomalodesmata (Mollusca, Bivalvia) and phylogenetic implications

et al. 2018

Anomalodesmata is the rarest and most specialized group of the class Bivalvia. In general, scarce data on sperm ultrastructure of anomalodesmatans are available in the literature. Aiming to contribute to an understanding of spermatozoon morphology in this group, the present study describes the ultrastructure of male gametes of three species—Cardiomya cleryana (Orbigny 1842) (Cuspidariidae), Pandora brevirostris Güller and Zelaya 2016 (Pandoridae) and Thracia similis Couthouy 1839 (Thraciidae). C. cleryana has an acrosome located at the anterior region, and the mitochondria are symmetrically arranged, while the spermatozoa of P. brevirostris and T. similis have unique characteristics, in particular the association of the acrosome with the midpiece and asymmetric mitochondria. This position of the acrosome appears to be peculiar among Anomalodesmata and is unknown for non‐anomalodesmatan bivalves. The present ultrastructural description of spermatozoa contributes to differentiate the studied species, bringing new insights about the sperm features of anomalodesmatan species and shares several characteristics with that of other species of the two lineages proposed by molecular phylogeny.

“…At the São Paulo coast, three species were found in the São Sebastião channel, on the shore of the São Sebastião Island (MIGOTTO et al 1993, SALVADOR et al 1998, and on the rocky shores of São Francisco (DENADAI & AMARAL 1999). The greatest colour plate diversity of individuals was observed on the coast of Rio de Janeiro (RODRIGUES & ABSALÃO 2005).…”
