Local v. microhabitat influences on the fish fauna of tidal pools in north-east Brazil.
This study explored the influence of microhabitat characteristics, such as sandy, rocky and algal bottom, holes, area and depth, on tide-pool fish descriptors (evenness, total number of fish, diversity and species richness) and found that sites might play a major role for the rockpool ichthyofauna in north-east Brazil.
The effect of climate change on the distribution of a tropical zoanthid (Palythoa caribaeorum) and its ecological implications
The present distribution of P. caribaeorum shows that parts of the Brazilian coast, Caribbean Sea, and Florida are suitable regions for the species, as they are characterized by high salinity and pH and small temperature variation.
Ascidians from Rocas Atoll, northeast Brazil
The results indicate a high degree of endemism in the ascidian fauna from Rocas Atoll, where didemnids are presently the most important members.
Biological activity in extracts of ascidians (Tunicata, Ascidiacea) from the northeastern Brazilian coast
This study examined the cytotoxic potential of 10 ascidians found in the coastal waters of Northeast Brazil and found a strong inhibition of the sea urchin egg cell cycle during both phases examined, first cleavage and blastula, with a possible action on the cell microfilament apparatus.
Rhodoliths in Brazil: Current knowledge and potential impacts of climate change
Bancos de rodolitos formam oasis de alta biodiversidade em ambientes marinhos de fundo arenoso. Os rodolitos sao formados por especies bioconstrutoras, que fornecem abrigo e substrato para diversas e…
Reef fish assemblage and zoogeographic affinities of a scarcely known region of the western equatorial Atlantic
Based only on assemblage composition, the reef fish fauna from Ceará showed a strong resemblance (73%) with the reefs of Risca do Zumbi and Paraiba and suggest ecological factors as the main drivers of the fish assemblages in the region.

Given that marine heat waves produce an increase of turf cover on the shallow reefs of the Abrolhos, a decrease in the cover represented by reef builders and shifting carbonate production are expected in the near future.
Cytotoxicity of actinomycetes associated with the ascidian Eudistoma vannamei (Millar, 1977), endemic of northeastern coast of Brazil
A bioactivity-guided screening among actinomycetes, associated with E. vannamei, aims at recognizing active principles with biological relevance, and identifies five strains as Micromonospora spp.
Molecular phylogeny of Didemnidae (Ascidiacea: Tunicata)
This paper presents a meta-anatomy of the seabed of the Atlantic Ocean and some of thebuilding blocks of itsbuilding blocks, which have been studied in greater detail in detail in the literature on Tropical Marine Sciences.
Water Toxicity Assessment of the Ceará River Estuary (Brazil)
The Ceara River Basin is one of the three major water sources of the Metropolitan Region of Fortaleza, Ceara State, Brazil. As an urban river, it receives domestic and industrial effluents, but the…
