A census of the biomass on Earth is key for understanding the structure and dynamics of the
biosphere. However, a global, quantitative view of how the biomass of different taxa …

Quantifying the rates of biogeochemical processes in marine sediments is essential for
understanding global element cycles and climate change. Because organic matter …

Glycerol dialkyl glycerol tetraether (GDGT) lipids are membrane lipids which were long
thought to be synthesized mainly by archaea, organisms thought to be limited to extreme …

The global geographic distribution of subseafloor sedimentary microbes and the cause (s) of
that distribution are largely unexplored. Here, we show that total microbial cell abundance in …

A great number of the bacteria and archaea on Earth are found in subsurface environments

Bathyarchaeota, formerly known as the Miscellaneous Crenarchaeotal Group, is a phylum of
global generalists that are widespread in anoxic sediments, which host relatively high …

The neonate is exposed to the maternal vaginal microbiota during parturition, providing the
primary source for normal gut colonization, host immune maturation, and metabolism. These …

The leakage of cold, methane-rich fluids from subsurface reservoirs to the sea floor at
specific sites on continental slopes, termed cold seeps, sustains some of the richest …
