Here we review the application of molecular biological approaches to mineral precipitation
in modern marine microbialites. The review focuses on the nearly two decades of nucleotide …

Mars has been subject to repeated waxing and waning episodes of extreme chaotic
obliquity (axial tilting) for at least four billion years. Obliquity is currently at 25.19 degrees …

Microbial mat communities possess extensive taxonomic and functional diversity, which
drive high metabolic rates and rapid cycling of major elements. Modern microbial mats …

Stromatolites are organosedimentary build-ups that have formed as a result of the sediment
trapping, binding and precipitating activities of microbes. Today, extant systems provide an …

Microbial communities play essential roles in the biosphere and understanding the
mechanisms underlying their functional adaptations to environmental conditions is critical for …

Background Marine heterotrophic flagellates (HF) are dominant bacterivores in the ocean,
where they represent the trophic link between bacteria and higher trophic levels and …

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

Microbialites are organo-sedimentary structures formed by complex microbial communities
that interact with abiotic factors to form carbonate rich fabrics. Extraction of DNA or total RNA …

As a variety of non-laminated microbial carbonate or calcified microbialite, thrombolites
commonly comprise diffusely clotted micrites as their basic structural unit. The current study …

Billions of years ago, the Northern Hemisphere of Mars may have been covered by at least
one ocean and thousands of lakes and rivers. These findings, based initially on telescopic …
