Coarsely crystalline cryogenic cave carbonate – a new archive to estimate the Last Glacial minimum permafrost depth in Central Europe [PDF]

open access: yesClimate of the Past, 2012
Cryogenic cave carbonate (CCC) represents a specific type of speleothem whose precipitation is triggered by freezing of mineralized karst water. Coarsely crystalline CCC, which formed during slow freezing of water in cave pools, has been reported from 20

Characteristics and formation mechanism of karst collapse in Yunnan Plateau

open access: yesZhongguo dizhi zaihai yu fangzhi xuebao, 2022
The general characteristics of karst collapse in Yunnan plateau is comprehensively influenced and determined by the specific geological environment, karst development, hydrogeology, hydrometeorology and human engineering activities. This article analyses

Modeling air pressure propagation through Wind Cave and Jewel Cave: How can air pressure signals inside barometric caves be predicted from surface pressure measurements?

open access: yesInternational Journal of Speleology, 2022
Recent speleoclimatological research has shed new light on air pressure dynamics inside barometric caves by identifying pressure-modifying processes and resulting systematic differences between cave and surface air pressure.

The faunistic diversity of cave-dwelling spiders (Arachnida, Araneae) of Greece [PDF]

open access: yes, 2011
Until today, from Greek caves a total of 109 species of spiders belonging to 25 families are known. One species, the linyphiid Porrhomma convexum (Westring, 1861) was recorded here for the first time in Greece. The 109 species are distributed in caves of

Deep time in Cave of Forgotten Dreams

open access: yesScreen, 2020
This essay considers how Werner Herzog’s 3D documentary Cave of Forgotten Dreams (2011) presents the entanglement of human drawing with natural formations of rock in a place where beauty is repeatedly ascribed to both these elements – the spectacular Chauvet Cave in the Ardèche gorge in France.

Identifying tree roots in the caves of Quintana Roo, Mexico as a step toward ecological insights and improved conservation

open access: yesPlants, People, Planet, 2020
Societal Impact Statement Caves in Quintana Roo, Mexico are known for spectacular calcite formations, blue water, and their significance in Mayan culture. A fascinating feature of these caves is the tree roots that emerge from ceilings, walls, and floors.

Peculiar Minerogenetic Cave Environments of Mexico: The Cuatro Ciénegas Area

open access: yesActa Carsologica, 2006
The karst area of Quatro Ciénegas (Coahuila, Mexico) represents an ideal site to study cave mineralogy, because it hosts caves of different age and genesis (karst, thermal, mine caves).

Evaporite-karst processes, landforms, and environmental problems [PDF]

open access: yes, 2008
Evaporite karst is widespread, but relatively unknown when compared with carbonate karst; this special issue addresses that lack of familiarity. Evaporite rocks have much higher solubilities and faster dissolution rates than carbonate rocks and they also

Hibernacula of greater horseshoe bat Rhinolophus ferrumequinum (Schreber, 1774): data from four deep caves in Slovenia

open access: yesNatura Sloveniae
In this paper, we present data on not yet surveyed hibernacula of the greater horseshoe bat (Rhinolophus ferrumequinum) from three deep caves in SE Slovenia (Čaganka, Kaščica, Topli vrh 5) and one in W Slovenia.

Surface runoff alters cave microbial community structure and function.

open access: yesPLoS ONE, 2020
Caves formed by sulfuric acid dissolution have been identified worldwide. These caves can host diverse microbial communities that are responsible for speleogenesis and speleothem formation.
