    Araçá Bay (São Sebastião, State of São Paulo), within one of Brazil's most beautiful coastlines, has small relict mangrove stands and a very diverse marine ecosystem. As such, the bay is a natural laboratory as well as important for local small scale fishing. In this study we summarize the large literature base to comprehensibly list the flora and fauna as a preliminary biodiversity inventory of Araçá Bay. We place this in the historical context of human impact on the environment of the bay and we emphasize new, introduced and threatened species as bioindicators and natural resources. With this information, we provide a basis to inform conservation decisions as well as data for conservation management plans and call attention to the urgent need to protect this fragile environment and biota. We also emphasize that this small and uniquely biologically rich bay should be preserved, revitalized and integrated into the growing urban environment.101219264Amaral, A.C.Z., Morgado, E.H., Alteraciones en la fauna de anélidos poliquetos de Araçá, São Sebastião (SP - Brasil) (1994) Rev.

    Complete mitochondrial genome sequences of Atlantic representatives of the invasive Pacific coral species Tubastraea coccinea and T. tagusensis (Scleractinia, Dendrophylliidae): implications for species identification

    No full text
    Members of the azooxanthellate coral genus Tubastraea are invasive species with particular concern because they have become established and are fierce competitors in the invaded areas in many parts of the world. Pacific Tubastraea species are spreading fast throughout the Atlantic Ocean, occupying over 95% of the available substrate in some areas and out-competing native endemic species. Approximately half of all known coral species are azooxanthellate but these are seriously under-represented compared to zooxanthellate corals in terms of the availability of mitochondrial (mt) genome data. In the present study, the complete mt DNA sequences of Atlantic individuals of the invasive scleractinian species Tubastraea coccinea and Tubastraea tagusensis were determined and compared to the GenBank reference sequence available for a Pacific "T. coccinea" individual. At 19,094 bp (compared to 19,070 bp for the GenBank specimen), the mt genomes assembled for the Atlantic T. coccinea and T. tagusensis were among the longest sequence determined to date for "Complex" scleractinians. Comparisons of genomes data showed that the "T. coccinea" sequence deposited on GenBank was more closely related to that from Dendrophyllia arbuscula than to the Atlantic Tubastraea spp., in terms of genome length and base pair similarities. This was confirmed by phylogenetic analysis, suggesting that the former was misidentified and might actually be a member from the genus Dendrophyllia. In addition, although in general the COX1 locus has a slow evolutionary rate in Scleractinia, it was the most variable region of the Tubastraea mt genome and can be used as markers for genus or species identification. Given the limited data available for azooxanthellate corals, the results presented here represent an important contribution to our understanding of phylogenetic relationships and the evolutionary history of the Scleractinia

    Locomotion of Stramonita haemastoma (Linnaeus) (Gastropoda, Muricidae) on a mixed shore of rocks and sand

    Mixed shores of rocks and sand are appropriate systems for the study of limitations that the isolation of rocks may impose for gastropods that typically inhabit rocky shores. We marked 52 Stramonita haemastoma (Linnaeus, 1767) snails on a mixed shore and found that 34 of them moved between rocks one to four times during 15 surveys in a period of 72 days. In the experiments, the snails moved on rock by continuous, direct, ditaxic, alternate undulations of the foot sole but on submerged sand they used slower arrhythmic discontinuous contractions of the foot sole. They switched between modes of locomotion in response to the type and topography of the substrate and possibly to water dynamics. In nature, snails moved between rocks forming aggregations where they oviposited. This may have masked other causes of movement, such as availability of prey. Most snails burrowed into the sand when the rocks became exposed during low tides. Further experiments are needed to explicitly address the possible causes of movements among rocks and burial
