Rare species are increasingly recognized as crucial, yet vulnerable components of Earth’s
ecosystems. This is also true for microbial communities, which are typically composed of a …

Soils harbor a substantial fraction of the world’s biodiversity, contributing to many crucial
ecosystem functions. It is thus essential to identify general macroecological patterns related to …

Subsurface ecosystems like groundwater harbour diverse microbial communities, including
small‐sized, putatively symbiotic organisms of the Candidate Phyla Radiation, yet little is …

The terrestrial subsurface contains nearly all of Earth’s freshwater reserves and harbours the
majority of our planet’s total prokaryotic biomass. Although genetic surveys suggest these …

The emission of methane (1.3 mmol of CH 4 m −2 day −1 ), precursors of methanogenesis,
and the methanogenic microorganisms of acidic bog peat (pH 4.4) from a moderately …

To evaluate the microbial populations involved in the reduction of Fe(III) in an acidic, iron-rich
sediment, the anaerobic flow of supplemental carbon and reductant was evaluated in …

Despite the widely observed predominance of Cand. Patescibacteria in subsurface
communities, their input source and ecophysiology are poorly understood. Here we study …

Using a combination of cultivation-dependent and -independent methods, this study aimed to
elucidate the diversity of microorganisms involved in iron cycling and to resolve their in situ …

The anoxic sediment of an acidic (pH ∼3) iron‐ and sulfate‐rich lake and its pore water was
studied with respect to the turnover rates of solid and dissolved iron and sulfur species. …

Karstic caves represent one of the most important subterranean carbon storages on Earth
and provide windows into the subsurface. The recent discovery of the Herrenberg Cave, …
