Sulfur Cave (Romania), an extreme environment with microbial mats in a CO2-H2S/O2 gas chemocline dominated by mycobacteria
Serban M. Sarbu, Joost W. Aerts, Jean-François Flot, Rob J.M. Van Spanning, Calin Baciu, Artur Ionescu, Boglárka M. Kis, Reka Incze, Sándor Sikó-Barabási, Zoltan Para, Botond Hegyeli, Nicu-Viorel Atudorei, Casey Barr, Kenneth Nealson, Ferenc L. Forray, Cristian Lascu, Emily J. Fleming, Wilbert Bitter, and Radu Popa

  • Sulfur Cave (Romania) is fed by mofettic emissions of CO2, CH4, H2S, and water vapors
  • A redox gas chemocline (i.e. oxic/anoxic gas/gas interface) occurs in Sulfur Cave
  • Microbial biofilms colonize the cave walls at the gas/gas interface
  • Below the interface, rich deposits of twinned and elongated sulfur crystals are found
  • Sulfur Cave biofilms are important in the search for life in extreme environments


Evidence for subsurface origin of boulder caves, roofed slots and boulder-filled canyons (Broumov Highland, Czechia)
Filip Duszyński, Kacper Jancewicz, and Piotr Migoń

  • Extensive boulder fills of canyon floors interpreted as residual materials
  • Subsidence into voids the likely process of origin of boulder fills, not rock fall
  • Boulders caves in canyons are not talus caves
  • Roofed slots provide analogy to explain larger landforms
  • Geomorphometry assists in characterizing geomorphic diversity of canyons


Underground dinosaur tracksite inside a karst of southern France: Early Jurassic tridactyl traces from the Dolomitic Formation of the Malaval Cave (Lozère)
Jean-David Moreau, Vincent Trincal, Daniel André, Louis Baret, Alain Jacquet, and Michel Wienin

  • Hettangian tridactyl dinosaur tracks were discovered in the Malaval Cave (southern France)
  • The tracksite was studied using photogrammetric imaging technique
  • More than 26 footprints of theropods were identified
  • The depositional environment varied from subtidal to intertidal/supratidal flat marsh
  • This work highlights the great interest to heighten palaeoichnological prospections in karsts


A world review of fungi, yeasts, and slime molds in caves
Karen J. Vanderwolf, David Malloch, Donald F. McAlpine, and Graham J. Forbes


Bacterial diversity associated with mineral substrates and hot springs from caves and tunnels of the Naica Underground System (Chihuahua, Mexico)
Adriana Espino del Castillo, Hugo Beraldi-Campesi, Patricia Amador-Lemus, Hiram Isaac Beltrán, and Sylvie Le Borgne

  • Bacterial communities present on mineral substrates and in hot springs were studied
  • DGGE showed communities grouping according to substrate type and sample location
  • Bacterial isolates included Firmicutes, Beta- and Gammaproteobacteria
  • Some strains could precipitate calcium carbonate and iron(III) in solid media
  • This study is the first reporting the isolation of microorganisms from Naica
