A wide array of microorganisms, including many novel, phylogenetically deeply rooted taxa,
survive and thrive in extreme environments. These unique and reduced-complexity …

Understanding the role of biology in planetary evolution remains an outstanding challenge
to geobiologists. Progress towards unravelling this puzzle for Earth is hindered by the …

Soil warming can directly affect the microbial community, or indirectly affect the microbial
community by affecting soil moisture, nutrient availability, vegetation growth, etc. However …

Phototrophic microbial mats are ideal model systems for ecological and evolutionary
analysis of highly diverse microbial communities. Microbial mats are small-scale, nearly …

Cyanobacteria use three major photosynthetic complexes, photosystem (PS) I, PS II and
phycobilisomes, to harvest and convert sunlight into chemical energy. Until recently, it was …

Cyanobacteria have evolved a number of acclimation strategies to sense and respond to
changing nutrient and light conditions. Leptolyngbya sp. JSC-1 was recently shown to …

The Yellowstone geothermal complex contains over 10,000 diverse geothermal features that
host numerous phylogenetically deeply rooted and poorly understood archaea, bacteria …

The results of recent biofilm characterizations have helped reveal the complexities of these
surface‐associated communities of microorganisms. The activities of the cells and the …

Microbial populations living in environments with temperatures above 50° C (thermophiles)
have been widely studied, increasing our knowledge in the composition and function of …

Photosynthetic bacteria are abundant in alkaline, terrestrial hot springs and there is a long
history of research on phototrophs in Yellowstone National Park (YNP). Hot springs provide …
