1. Composition and biological activities of the aqueous extracts of three scleractinian corals from the Mexican Caribbean: Pseudodiploria strigosa, Porites astreoides and Siderastrea siderea
Abstract Background: Scleractinian corals (stony corals) are the most abundant reef-forming cnidarians found in coral reefs throughout the world. Despite their abundance and ecological importance, information about the diversity of their toxins and their biological activities is very scarce. In this study, the chemical composition and the biological activit

2. The non-indigenous bryozoan Triphyllozoon (Cheilostomata: Phidoloporidae) in the Atlantic: morphology and dispersion on the Brazilian coast
ABSTRACT Bryozoans constitute an important component of marine-fouling communities of anthropogenic substrata. Many species have been reported as exotic or widespread around the world, typically in ports and harbors of non-polar regions. Here we present the first record of a species of the bryozoan Triphyllozoon in the Atlantic Ocean. Triphyllozoon arcuatum

3. Avaliação da defesa química e da influência dos corais invasores Tubastraea coccinea e Tubastraea tagusensis na estruturação das comunidades bentônicas da Baía da Ilha Grande RJ / Assessment of chemical defense and negative impact of the invasive corals Tubastraea coccínea and Tubastraea tagusensis on benthic community structure in Ilha Grande Bay - RJ
A introdução de espécies invasoras marinhas tem causado danos econômicos e ecológicos consideráveis em todo o mundo. Algumas destas espécies incluindo corais escleractíneos possuem adaptações, tais como metabólitos secundários utilizados para evitar a predação e competição por espaço por outros organismos. Este arsenal químico e as interaç

4. PHYLOGENETICS AND MORPHOLOGICAL EVOLUTION OF SCLERACTINIAN CORALS
Scleractinian corals are modular organisms of great ecological and economic importance that may have solitary or colonial growth forms. In spite of the rich fossil record, the evolutionary history of the group is poorly understood and its taxonomy is highly artificial because many of the features commonly employed in systematic studies of the group exhibit l

5. Bacterial Community Associated with Black Band Disease in Corals
Black band disease (BBD) is a virulent polymicrobial disease primarily affecting massive-framework-building species of scleractinian corals. While it has been well established that the BBD bacterial mat is dominated by a cyanobacterium, the quantitative composition of the BBD bacterial mat community has not described previously.

6. Membrane lipids of symbiotic algae are diagnostic of sensitivity to thermal bleaching in corals
Over the past three decades, massive bleaching events of zooxanthellate corals have been documented across the range of global distribution. Although the phenomenon is correlated with relatively small increases in sea-surface temperature and enhanced light intensity, the underlying physiological mechanism remains unknown. In this article we demonstrate that

7. Aragonite crystallization in primary cell cultures of multicellular isolates from a hard coral, Pocillopora damicornis
The foundation of marine coral reef ecosystems is calcium carbonate accumulated primarily by the action of hard corals (Coelenterata: Anthozoa: Scleractinia). Colonial hard coral polyps cover the surface of the reef and deposit calcium carbonate as the aragonite polymorph, stabilized into a continuous calcareous skeleton. Scleractinian coral skeleton composi
