Abstract
- At deep sea hydrothermal fields, a mixing gradient between hot reduced fluids and cold oxygenated sea water creates a number of micro-environments with different physico-chemical conditions in direct proximity to each other. Although many of the key microorganisms in these environments have been identified and described, a systematic understanding of their distribution across the mixing gradient and their niche partitioning is still missing. In my doctoral thesis, I investigated the interplay of geochemical settings, microbial community structures, and diversification of microorganisms in three collaborative studies of hydrothermal vent fields in the Atlantic and Pacific Oceans. Taken together, this thesis provides a detailed overview of the microbial community structures in hydrothermal vents. It deepens our understanding of niche differentiation of major marine sulfur oxidizers, and offers valuable insights into microbial diversification.
