Redox-controlled restructuring of marine microbial ecosystems during oceanic anoxic events

During the Phanerozoic, the ocean repeatedly experienced periods of widespread deoxygenation known as oceanic anoxic events. Geological records from these events indicate a profound shift in marine microbial ecosystems. While cyanobacterial biomarkers are found broadly, those of anoxygenic photosynthetic green sulfur b...
