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...
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...
Dictyota is a brown algae genus inhabiting tropical to warm temperate environments where it an important food source, shelter and substrate several species of invertebrates other algae. The taxonomy this troublesome, with poor delimitation doubtful records in the literature. dichotoma, type genus, was commonly accepted as cosmopolitan because inaccurate geographical distributional range consequence misidentification parts world. Recent studies molecular data revealed new understanding...
The present study describes the community diversity and gives a seasonal distribution of an intertidal macroalgal assemblage at Prainha Beach, Arraial do Cabo City in Rio de Janeiro state, Brazil. Sampling was performed during four seasons 1-year period. Organisms were sampled photographed using photoquadrats to quantify relative coverage. Ninety-six taxa macroalgae registered, including 23 chlorophytes, 19 ochrophytes, 54 rhodophytes, while three barnacles, seven mollusks, one isopod,...
Macroalgae of the genus Dictyota produce large amount diterpenes, which have many ecological and biological functions. We analysed crude extracts three Brazilian populations brown alga ciliolata by hydrogen nuclear magnetic resonance (1H-NMR) spectroscopy high-resolution gas chromatography coupled to mass spectrometry (HRGC/MS). All HRGC/MS profiles showed that D. contained prenylated guaiane (Group I), xeniane, crenulidane diterpenes III) as major constituents. Eleven were detected, dictyol...
