The class Echinoidea contains among the best-known echinoderms. group has left most complete fossil record of this phylum, and about 1000 living species, which 51 are recorded along Brazilian coast. Although first echinoids in Brazil was made 369 years ago, knowledge fauna remains quite unsatisfactory from a taxonomic ecological point view, particularly north northeastern regions country. This study provides annotated list Brazil. studied material largely belongs to collections Federal...
The Santos Basin (SB) is the main petroliferous basin in Brazilian continental margin and one of most studied marine areas Brazil. However, historical data suggest that new efforts should be carried out to acquire quantitative biological data, especially deep sea, establish baseline essential ocean variables different ecosystems for future monitoring programs. energy company Petrobras planned executed 24 oceanographic cruises over a period 2 years assess benthic (SANSED cruise) pelagic...
Abstract Aim Knowledge gaps and sampling bias can lead to underestimations of species richness distortions in the known distribution species. The goal this study is identify potential biases marine organisms at Western Atlantic Ocean, determine their causes assess its effect on biodiversity metrics. We tested interference with representation environmental conditions, potentially affecting model predictions. Location Ocean. Methods This compiled data online institutional databases. analysis...
Crinoids are commonly associated with corals, but whether they physiologically interact is unclear. Like crinoids host symbiotic microorganisms little known about the crinoid microbiome. Here, we reveal microbiomes of deep-sea corals Desmophyllum pertusum and Solenosmilia variabilis and, notably, their feather star crinoid, Koehlermetra (of family Thalassometridae) in Campos Basin, Brazil. We showed that same endosymbiotic members families Endozoicomonadaceae Nitrosopumilaceae...
Abstract Aim Understanding the factors determining marine community variations is important for biogeography and conservation. Beta diversity a metric mapping species composition between communities regionalizing biota. Ecoregions are commonly used regionalization, but their empirical testing has been limited. Our aim to map in Western Atlantic, identify variables related these variations, regionalize areas based on distribution. Additionally, we test whether currently proposed ecoregions...

Most species of Taeniogyrus Semper, 1867 are known from shallow water in the Indo-Pacific, with other records Antarctica, Mediterranean Sea, and Atlantic. A new is described illustrated here continental slope Campos Basin, southeast Brazil. In this species, sigmoid hooks (336–405 µm) much larger than any genus, bearing a long conspicuous hook region. Wheels six spokes (86–169 µm), inner margin 60–125 continuous teeth, confined to round papillae along each interradius. Polian vesicles...
O objetivo desta pesquisa foi avaliar a qualidade microbiológica e o perfil ácido-láctico do queijo de coalho artesanal. Todas as amostras apresentaram coliformes totais, termotolerantes presença Escherichia coli, porém com os valores dentro dos padrões estabelecidos pela legislação vigente no país. estudado mostrou uma microbiota heterogênea, constituída por lactobacilos, lactococos, estreptococos enterococos, confirmadas espécies Enterococcus faecalis, faecium, Streptococcus thermophilus...
Continental margins usually have a high degree of environmental heterogeneity, which, in turn, promotes benthic biodiversity. The South-Southeast regions concentrate the most well-mapped areas Brazilian continental margin regarding seafloor geomorphology and physical oceanography. However, structure soft-sediment fauna slope is still unknown. Characterization understanding biota are imperative since human activities increasing last decades, especially after discovery pre-salt reservoir...
The sea urchin Centrostephanus longispinus rubicingulus was rediscovered on the continental shelf of Brazil. subspecies merely recorded in 1955, when Bernasconi described besnardi (a synonym C. rubicingulus), basis two specimens collected at Trindade Island (State Espírito Santo). This is first record this for northeastern Brazil Rio Grande do Norte). A description provided, along with comments morphology and synonymy, illustrations diagnostic characters and, time, SEM figures pedicellariae...
