High‐sulfur, low‐oxygen environments formed by underwater sinkholes and springs create
unique habitats populated by microbial mat communities. To explore the diversity and …

Little is known about large sulfur bacteria (LSB) that inhabit sulfidic groundwater seeps in
large lakes. To examine how geochemically relevant microbial metabolisms are partitioned …

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

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

Animal migrations mark the largest daily movement of biomass on Earth today, but who
performed the first diel migration and what are the implications? Modern-day benthic …

Cyanobacteria are diverse prokaryotic, photosynthetic organisms present in nearly every
known ecosystem. Recent investigations around the world have recovered vast amounts of …

The sedimentary pyrite sulfur isotope (δ34S) record is an archive of ancient microbial sulfur
cycling and environmental conditions. Interpretations of pyrite δ34S signatures in sediments …

Community dynamics within microbial mat assemblages are complex, likely involving
intricate metabolic linkages. Interactions between microbes shape these communities …

A region of Lake Huron near Alpena, Michigan (USA) includes karstic sinkholes with oxygen-
poor, sulfur-rich ground water that contain vibrant microbial mats resembling life in early …

Cyanobacteria are Gram‐stain‐negative, oxygenic phototrophic bacteria, and nearly all
species possess photosystems I and II. They show a considerable physiological and …
