Among fundamental research questions in subterranean biology, the role of subterranean
microbiomes playing in key elements cycling is a top-priority one. Karst caves are widely …

Caves are typified by their permanent darkness and a shortage of nutrients. Consequently,
bacteria play an important role in sustaining such subsurface ecosystems by dominating …

Of the several critical challenges present in environmental microbiology today, one is the
assessment of the contribution of microorganisms in the carbon cycle in the Earth-climate …

On November 5–8, 2019, the “Mars Extant Life: What's Next?” conference was convened in
Carlsbad, New Mexico. The conference gathered a community of actively publishing experts …

Abstract Castañar Cave (Caceres, Spain) is a unique show cave known for its high natural
radiation levels. This study presents a comprehensive analysis of its prokaryotic diversity …

The physicochemical properties and microbial communities have significant annual and
seasonal changes in karst aquifers. To explore the changes of microbial community and …

Karst caves are widely distributed subsurface systems, and the microbiomes therein are
proposed to be the driving force for cave evolution and biogeochemical cycling. In past …

The carbonate critical zone (CZ) is characterized by extensive groundwater-surface water
exchange that leads to highly variable redox states of groundwater. Changes in redox …

Karst caves are recently proposed as atmospheric methane sinks in terrestrial ecosystems.
Despite of the detection of atmospheric methane‐oxidizing bacteria (atmMOB) in caves, we …

Microorganisms are thought to play a critical role in methane (CH4) consumption in karst
caves and yet the presence and diversity of methane-oxidizing bacteria (MOB) remain a …
