Since its discovery over two decades ago, the deep subsurface biosphere has been considered to be the realm of single-cell organisms, extending over three kilometres into the Earth’s crust and comprising a significant fraction of the global biosphere. The constraints of temperature, energy, dioxygen and space seemed to preclude the possibility of more-complex, multicellular organisms from surviving at these depths. Here we report species of the phylum Nematoda that have been detected in or… 
Eukaryotic opportunists dominate the deep-subsurface biosphere in South Africa
TLDR
Characterization of the different species reveals that many are opportunistic organisms with an origin due to recharge from surface waters rather than soil leaching, and calculations suggest that food, not dissolved oxygen is the limiting factor for eukaryal population growth.

TLDR
It is concluded that the fossil record of Earth's largest microbial habitat may still have much to tell us about the history of life, the evolution of biogeochemical cycles, and the search for life on Mars.
The deep continental subsurface: the dark biosphere
TLDR
The number and diversity of microorganisms decrease with depth, and the abundance of Bacteria is superior to Archaea, and methanogens are recurrently detected in most analyzed subsurface samples.
From Genes to Metagenomes: Exploring life underground
TLDR
A picture of how microbial communities function in the terrestrial subsurface is provided as well as a theoretical framework for understanding the selective pressures these organisms face.
Microbial Diversity in Deep-Subsurface Hot Brines of Northwest Poland: from Community Structure to Isolate Characteristics
TLDR
This study shows that low-diversity microbial assemblages in subsurface hot brines were dominated by the bacteria involved in biogeochemical cycles of sulfur and nitrogen, and indicates that some lineages of B. paralicheniformis are halothermophilic, which was not previously reported.
Microsporidia-nematode associations in methane seeps reveal basal fungal parasitism in the deep sea
TLDR
It is revealed that methane seeps support complex ecosystems involving interkingdom interactions between bacteria, nematodes, and parasitic fungi and that microsporidia parasitism exists also in the deep-sea biosphere.

Subsurface microbial communities in sediment and fractured rock environments beneath continental surface environments and beneath the ocean floor comprise a significant but largely unexplored portion
New ecosystems in the deep subsurface follow the flow of water driven by geological activity
TLDR
The results show there is a steady flow of surface organisms to the deep subsurface where some survive and adapt and others perish and the mechanism elucidated here may be relevant for future search and selection of landing sites in planetary exploration.
A global perspective on microbial diversity in the terrestrial deep subsurface
TLDR
The diversity of bacterial communities in deep subsurface groundwater is shown to be controlled by aquifer lithology globally, by using 16S rRNA gene datasets collected across five countries on two continents and from fifteen rock types over the past decade.
Detection of the deep biosphere in metamorphic rocks from the Chinese continental scientific drilling
TLDR
The results support the notion that temperature is a key factor in determining the lower limit of the biosphere in the continental subsurface.

The first metazoa living in permanently anoxic conditions
TLDR
This is the first evidence of a metazoan life cycle that is spent entirely in permanently anoxic sediments, and it is concluded that these metazoans live under anoxic conditions through an obligate anaerobic metabolism that is similar to that demonstrated so far only for unicellular eukaryotes.
Characterisation of Yeasts Isolated from Deep Igneous Rock Aquifers of the Fennoscandian Shield
TLDR
Five yeast, three yeastlike, and 17 mold strains were isolated from Äspö HRL groundwater to determine whether they were adapted to life in the deep biosphere, and grew within a pH range of 4–10, between temperatures of 4°C and 25–30°C, and in NaCl concentrations from 0 to 70 g L−1, suggesting a degree of adaptation to the groundwater at €HRL.

TLDR
The exclusive common presence of fungivorous and plant parasitic nematodes supports a long-standing hypothesis that states that plant parasitic Nematodes arose from fungivory ancestors.

Broad oxygen tolerance in the nematode Caenorhabditis elegans.
TLDR
Remarkably, long-term exposure to 100 % oxygen had no effect on the metabolic rate of C. elegans, and populations were able to survive for at least 50 generations in 100 % (90 kPa) oxygen.
