| Abstract | Although previous studies have described opposing states in upwelling regions, i.e., the
rise of cold nutrient-rich waters and prevalence of surface warm nutrient-poor waters, few
have addressed the transition from one state to the other. This study aimed to describe the
microbial and viral structure during this transition and was able to obtain the taxonomic and
metabolic compositions as well as physical-chemical data. This integrated approach
allowed for a better understanding of the dynamics of the downwelling upwelling transition,
suggesting that a wealth of metabolic processes and ecological interactions are occurring in
the minute fractions of the plankton (femto, pico, nano). These processes and interactions
included evidence of microbial predominance during downwelling (with nitrogen recycling
and aerobic anoxygenic photosynthesis), different viral predation pressures over primary
production in different states (cyanobacteria vs eukaryotes), and a predominance of diatoms
and selected bacterial and archaeal groups during upwelling (with the occurrence of a
wealth of nitrogen metabolism involving ammonia). Thus, the results provided insights into
which microbes, viruses and microbial-mediated processes are probably important in the
functioning of upwelling systems. | pt_BR |
