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.
