Abstract: Upwelling systems contain a high diversity of pelagic microorganisms and their composition and activity are defined by factors like temperature and nutrient concentration. Denaturing gradient gel electrophoresis (DGGE) technique was used to verify the spatial and temporal genetic variability of Bacteria and Archaea in two stations of the Arraial do Cabo coastal region, one under upwelling pressure and another under anthropogenic pressure. In addition, biotic and abiotic variables were measured in surface and d… Show more

“…In the studied region, upwelling events are seasonal and Sargassum growth occurs as a function of its intensity [14]. Thus, upwelling should be considered an important factor causing turnover in community composition of the benthic environment but also of planktonic prokaryotes [4] and eukaryotes [34] which are able to colonize the surface of macroalgal blades [5]. It is expected that Sargassum also selects its biofilm composition since Sargassum produces compounds with antioxidant, antibacterial, antitumoral, antimalarial, antiherbivory and antifouling properties [e.g.…”

“…In another work, by using DGGE, the same research group found that the archaeal communities were more homogeneous than the bacterial ones in water samples of sites with different degrees of upwelling and downwelling, as well as anthropogenic activities. The archaeal DNA sequences found were clustered in two groups: one associated with coastal waters archaea, and the other with open-sea archaeal DNA [26]. Taken together, the results obtained in these coastal waters studies revealed no significant differences in the archaeal communities of natural and polluted areas.…”

“…Moreover, in the MMW the occurrence of upwelling waters from the deep introduces additional complexity to this water mass that could mask possible tracing of water masses using the bacterial assemblage. Generally, in upwelling ecosystems, prokaryotic assemblages show a high spatial variability suggesting the importance of oceanographic features and anthropogenic impacts in shaping bacterial community structure [88].…”
