In the absence of sunlight, caves harbor a great diversity of microbial colonies to extensive
biofilms with different sizes and colors visible to the naked eye. One of the most widespread …

In cave environments, water vapor condensation occurs naturally when warmer/wet air
masses flow close to colder cave surfaces. Artificial microclimate perturbations in show …

Research on cave microorganisms has mainly focused on the microbial communities
thriving on speleothems, rocks and sediments; however, drip water bacteria and calcite …

Following the declaration of the COVID-19 pandemic, the Spanish Government restricted
non-essential movements of all citizens and closed all public spaces, such as the Nerja …

Abstract The volcanic Barva and Colima multiaquifer system is crucial for the drinking water
supply of about 1.7 million people, about 30% of the population in Costa Rica. The …

Rapid CO 2 degassing and calcite precipitation driven by cave ventilation influence the
speleothem δ 18 O and δ 13 C. However, the drivers of cave ventilation are not completely …

Rock moisture, which is considered as a hidden component of the terrestrial hydrological
cycle, has received little attention. In this study, the frequency-domain reflectometry (FDR) is …

Moonmilk-type deposits exemplify carbonated Martian analogues existing in the subsurface
of Earth, an endokarstic speleothem with a possible biochemical origin composed …

Corrosion processes were studied in epigenic caves of the Moravian Karst (MK). Samples of
naturally corroded speleothems and carbonate rocks collected in various MK caves were …

Water plays an important role in the deterioration of rocks. Often, the condensation cannot
be ignored in addition to the rain and seepage, especially for stone relics built with tuff in …
