Subterranean ecosystems play an active role in the global carbon cycle, yet only a few
studies using indirect methods have focused on the role of the cave microbiota in this critical …

Understanding the dynamics and distribution of CO2 in the subsurface atmosphere of
carbonate karst massifs provides important insights into dissolution and precipitation …

In recent decades speleothems have become valuable climate archives and are of crucial
importance for the investigation of past climate conditions. Albeit much progress has been …

Canonical models for speleothem formation and the subsurface carbon cycle invoke soil
respiration as the dominant carbon source. However, evidence from some karst regions …

The stable carbon isotope compositions of C 3 plants are controlled by the carbon isotope
composition of atmospheric CO 2 (δ 13 C a) and by the stomatal response to water stress …

Karst caves are potential sinks of atmospheric methane due to microbial consumption.
However, knowledge gaps on methanogens (methane producing microorganisms) and their …

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 …

Massive biofilms have been discovered in the cave of an iodine-rich former medicinal spring
in southern Germany. The biofilms completely cover the walls and ceilings of the cave …

Methane concentration in caves is commonly much lower than the external atmosphere, yet
the cave CH4 depletion causal mechanism is contested and dynamic links to external …

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 …
