Compared to bacteria, our knowledge of archaeal biology is limited. Historically,
microbiologists have mostly relied on culturing and single-gene diversity surveys to …

Organic carbon in marine sediments is a critical component of the global carbon cycle, and
its degradation influences a wide range of phenomena, including the magnitude of carbon …

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 …

Studies of marine benthic archaeal communities are updating our view of their taxonomic
composition and metabolic versatility. However, large knowledge gaps remain with regard to …

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

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

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 …

Methanogenic and methanotrophic archaea play important roles in the global flux of
methane. Culture-independent approaches are providing deeper insight into the diversity …

A great number of the bacteria and archaea on Earth are found in subsurface environments
in a physiological state that is poorly represented or explained by laboratory cultures …

Members of the archaeal phylum Bathyarchaeota are widespread and abundant in the
energy-deficient marine subsurface sediments. However, their life strategies have remained …
