Abstract Microbial communities dominate the fluxes of organic material in the ocean, in part due to their high abundance. To determine the amount of carbon processed by bacteria, bulk properties, such as production, abundance, biomass, and respiration, are measured for the total community. Phylogenetic analyses of bacteria are used to describe the structure within microbial communities. However, neither bulk activity measurements nor phylogenetic identification alone can determine which bacterial groups respond to certain environmental conditions or which bacterial groups use certain organic compounds. The goal of this dissertation was to assess the responses of different bacterial taxa to environmental conditions and available substrates. (mod. auth. abst.)
