Subterranean systems provide a suitable overwintering habitat for Salamandra salamandra
Monika Balogová, Dušan Jelić, Michaela Kyselová, and Marcel Uhrin

  • The strong connection of the life cycle of fire salamanders with underground shelters
  • Observing of population size, survival, recapture probability of wintering populations
  • Karstic areas can induce group wintering in the fire salamander
  • Regular visits important for reliable estimate of the number of wintering individuals
  • Higher heterogeneity of habitat causes greater underestimating of the wintering population


Timing of speleogenesis of Las Karmidas Cave (Mexico): first description of pseudokarst developed in ignimbrite
María del Pilar Aliaga-Campuzano, Rafael López-Martínez, Pablo Dávila-Harris, Ramón Espinasa-Pereña, Adriana Espino del Castillo, and J.P. Bernal

  • Cave hosted between ingnimbrite and calcareous diamicton, lavishly decorated with speleothems
  • Geochemical and geochronological constrains on the origin and development of the cave
  • Speleogenetic model based on stratigraphic, geochemistry and speloelogical surveys


The impact of door opening on CO2 levels: A case study from the Balcarka Cave (Moravian Karst, Czech Republic)
Marek Lang, Jiří Faimon, and Sandra Kejíková

  • The impact of cave door opening on cave CO2 levels differs with cave ventilation modes
  • Under the upward airflow mode, the opening of cave doors led to decrease of CO2 levels
  • Under the downward airflow mode, however, the cave door opening led locally to increase of CO2 levels
  • This increase may be explained by a change of airflow paths and additional input advective fluxes of CO2 from soils/epikarst


Mitigating the conflict between pitfall-trap sampling and conservation of terrestrial subterranean communities in caves
Peter Kozel, Tanja Pipan, Nina Šajna, Slavko Polak, and Tone Novak

  • Modified technique of pitfall trapping of the fauna in caves is presented
  • Amplified heterogeneity of sampled microhabitats improves biodiversity outcomes
  • The traditional sampling shows about 10% shortage in species richness
  • Suggested sampling approach mitigates sampling-fauna conservation conflicts


Screening of antifungal susceptibility in cave-dwelling aspergilli and report of an amphotericin B-resistant Aspergillus flavus
Erika L.S. Taylor, Gabriella F. Ferreira, Gustavo J.C. Freitas, Rodrigo L. Ferreira, Daniel de Assis Santos, and Maria A. de Resende-Stoianoff

  • Aspergillus spp. represent many of the identified species isolated from caves.
  • Aspergillus spp. can cause serious invasive opportunistic infections in humans.
  • A. flavus amphotericin B resistant was isolated from a cave.
  • A. flavus amphotericin B resistant is relied on higher ergosterol.
  • A. flavus amphotericin B resistant is relied on activity against oxidative stress.
