Seasonal changes in light and physicochemical conditions have strong impacts on
cyanobacteria, but how they affect community structure, metabolism, and biogeochemistry of …

Cyanobacteria are key members of modern photosynthetic microbial mats, by providing
organic matter and nutrients to the ecosystem. With their innovation of oxygenic …

Cyanobacterial mats profoundly influenced Earth's biological and geochemical evolution
and still play important ecological roles in the modern world. However, the biogeochemical …

Cyanobacteria are renowned as the mediators of Earth's oxygenation. However, little is
known about the cyanobacterial communities that flourished under the low‐O2 conditions …

Recently discovered submerged sinkholes in Lake Huron are high-sulfur, low-oxygen
extreme environments for microbial life. In order to understand the relationship between the …

Cyanobacterial mats were hotspots of biogeochemical cycling during the Precambrian.
However, mechanisms that controlled O2 release by these ecosystems are poorly …

We used microsensors to study the regulation of anoxygenic and oxygenic photosynthesis
(AP and OP, respectively) by light and sulfide in a cyanobacterium dominating microbial …

For a large part of earth's history, cyanobacterial mats thrived in low‐oxygen conditions, yet
our understanding of their ecological functioning is limited. Extant cyanobacterial mats …

We used microsensors to study short-term temperature effects on gross photosynthesis,
oxygen consumption and sulfate reduction in an extremely hypersaline (salinity 200‰) …

Bacterial sulfate reduction and transformations of thiosulfate were studied with radiotracers
in a Microcoleus chthonoplastes-dominated microbial mat growing in a hypersaline pond at …
