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

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 unique small-scale microclimatic gradient in a temperate karst harbours exceptionally high diversity of soil Collembola
Natália Raschmanová, Dana Miklisová, and Ľubomír Kováč

  • A karst doline with ice in a temperate zone harbours high diversity of Collembola
  • Cold zone of the doline provides climatic microrefugia for endemic and relict taxa
  • The doline serves as an ecotone between cave habitats and the surface environment
  • Cold microhabitats at the doline bottom are under the threat of climate warming

PDF

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

Extremely high diversity of sulfate minerals in caves of the Irazú Volcano (Costa Rica) related to crater lake and fumarolic activity
Andrés Ulloa, Fernando Gázquez, Aurelio Sanz-Arranz, Jesús Medina, Fernando Rull, José María Calaforra, Guillermo E. Alvarado, María Martínez, Geoffroy Avard, J. Maarten De Moor, and Jo De Waele

  • Mineralogical and geochemical studies of speleothems in caves of Irazú volcano were performed
  • Water and gas geochemistry of volcanic lake, infiltration waters and fumaroles are presented
  • Forty-eight different mineral phases were identified, mostly hydrated sulfates
  • We report the first occurrence of 13 minerals in cave environments, and 5 more yet to be confirmed
  • These caves are considered world-type locality for investigations of sulfate minerals

Antimicrobial activities of culturable microorganisms (actinomycetes and fungi) isolated from Chaabe Cave, Algeria
Larbi Belyagoubi, Nabila Belyagoubi-Benhammou, Valme Jurado, Joëlle Dupont, Sandrine Lacoste, Fatima Djebbah, Fatima Z. Ounadjela, Souad Benaissa, Salim Habi, Djamel E. Abdelouahid, and Cesareo Saiz-Jimenez

  • No publication has investigated the microbial diversity in cave ecosystems in Africa (or Algeria)
  • Main aim of this study was the identification of microorganisms with antimicrobial potential
  • The isolates were identified by molecular tools and tested for their bioactive compounds
  • The data indicated that the majority (72.86%) of the 70 isolates were active
  • The Chaabe Cave possesses a diversity of organisms that could lead to fresh sources of antibiotics
