Subterranean environments contribute to three‐quarters of classified ecosystem services
Biological Reviews, EarlyView.ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Modern methods in subsurface microbiology: in situ identification of microorganisms with nucleic acid probes [PDF]
FEMS Microbiology Reviews, 1997 Like many other parts of microbial ecology, subsurface microbiology has entered the molecular age. As one example of various powerful molecular techniques, fluorescently labeled rRNA-targeted nucleic acid probes today allow an in situ identification of individual microbial cells in their natural habitats.

Frontiers in Bioengineering and Biotechnology, 2018 Nitrous oxide (N2O) is a greenhouse gas and also leads to stratospheric ozone depletion. In natural environments, only a single N2O sink process is the microbial reduction of N2O to N2, which is mediated by nitrous oxide reductase (NosZ) encoded by nosZ ...
