Sources and sinks of methane (CH4 ) are critical for understanding global biogeochemical cycles and their role in climate change. A growing number of studies have reported that CH4 concentrations in cave ecosystems are depleted, leading to the notion that these subterranean environments may act as sinks for atmospheric CH4 . Recently, it was hypothesized that this CH4 depletion may be caused by...

The karst landscape is in the southern part of Malang Regency. In this area, separate phenomena can be seen on surface (eksokarst) and subsurface (endokarst). eksokarst indicated by an arid/dry area; meanwhile endokarst presence caves. This study aimed to understand use caves people Regency, existing potential inside cave passages, future challenges their utilization. used field observation alo...

A 4-yr study of spatial and temporal variability in the geochemistry of vadose groundwaters from caves within the Edwards aquifer region of central Texas offers new insights into controls on vadose groundwater evolution, the relationship between vadose and phreatic groundwaters, and the fundamental influence of soil composition on groundwater geochemistry. Variations in Sr isotopes and trace el...

Caves are nutrient-limited and dark subterranean ecosystems. To date, attention has been focused on geological research of caves in China, whilst indigenous microbial diversity has been insufficiently characterized. Here, we report the fungal diversity in the pristine, oligotrophic, karst Heshang Cave, central China, using a culture-dependent method coupled with the analysis of the fungal rRNA-...

Two new species of Khorata are described from China: K. ningyuan sp. nov. and K. sancai sp. nov. Both species were collected in caves.
