dc.description.abstractBacterioplankton communities play an important role in the flow of energy and nutrients through plankton food webs, as a consequence of their high abundance, efficient nutrient uptake and large growth potential. A number of studies have shown changes in bulk bacterial properties, as a response to biological or environmental factors. However, much less is known about how such factors may influence bacterial composition, and how potential shifts in bacterial assemblage structure may in turn influence microbial carbon processing. Even the distribution of the major phylogenetic groups of bacteria is still not well understood. We used mesocosm experiments to study the dynamics of the bacterioplankton assemblage in an extraordinarily hydrodynamic system during the four contrasting periods of the seasonal cycle: winter period, spring phytoplankton bloom, summer stratification and upwelling. We used a correlation approach in order to investigate the degree of coupling between bacterial diversity, carbon cycling and environmental factors. As a proxy for bacterial diversity we used the relative abundance of the most abundant phylogenetic groups of bacteria (Alphaproteobacteria, Gammaproteobacteria, and Bacteroidetes) as determined with CARD-FISH. Carbon flux-related variables included, primary production, extracellular release, bacterial production and microbial community respiration. The environmental set of factors and variables included temperature, concentrations of inorganic and organic nutrients, and chlorophyll-a concentration. Contrary to previous studies, we found out that even at this broad phylogenetic level, rapid shifts in bacterial assemblage structure occur associated to biotic and abiotic changes, and a significant correlation exists between bacterial diversity and both carbon flux and environmental factors. Microbial carbon processing also significantly correlated to environmental factorses_ES
