The International Journal of Speleology, the official journal of the Union Internationale de Spéléologie since 1978, has been published since 1964. It is a double-blind, peer-reviewed, international scientific journal that publishes research and review articles concerning all sciences involved in karst and caves, such as geology, geomorphology, hydrology, archaeology, palaeontology, (palaeo)climatology, biology, meteorology, microbiology, environmental sciences, physics, chemistry, mineralogy etc. IJS is published semiannually.
Articles are open access at http://scholarcommons.usf.edu/ijs. The journal is abstracted and indexed in the following services: Directory of Open Access Journals, ISI Thomson Services (Science Citation Index-Expanded including the Web of Science, ISI Alerting Service, Current Contents/Physical, Chemical and Earth Sciences), Bibliography & Index of Geology (GeoRef, Cambridge Scientific Abstracts, EarthScienceWISE (Oxmill Publishing), EBSCO publishing, Geobase, Speleological Abstracts (UIS), Ulrich’s Periodical Directory ™, BIOSIS Zoological record, SCOPUS (Elsevier), and SCImago Journal and Country Rank.

- A high variability of microbial biomass within a single cave system.
- Cave infrastructures containing heavy metals reduce the viability of microbiota.
- Underground habitats preserve and concentrate microbial biomass.

High-resolution signatures of oxygenation and microbiological activity in speleothem fluid inclusions
Nigel Blamey, Penelope J. Boston, and Laura Rosales-Lagarde
- Speleothem inclusions contain gases that can reflect past chemical and biological processes.
- Inclusion gas contents can be analyzed to high precision with quadrupole mass spectroscopy.
- CFS (crush fast scan) methodology enables high resolution analysis (30mg) withlimits.
- Each preliminary result has several possible explanations not yet distinguishable.
- Further technique development can help unravel geo, bio, and climate influences on inclusion gases.
The morphology and development of Kalahroud Cave, Iran
Shirin Bahadorinia, Sayed Hassan Hejazi, Alireza Nadimi, Derek C. Ford, and Karine Wainer
- Sub-horizontal maze cave in a cuesta of dipping limestones.
- Drains along the strike to an a-periodic river gorge in arid mountains.
- Morphology and sediment analysis show hypogene origin, with paragenesis.
- Corrosion notch rooms contain precipitate sequences, ending with calcite rafts of Holocene age
Seasonal temperature variations controlling cave ventilation processes in Cueva Larga, Puerto Rico
Rolf Vieten, Amos Winter, Sophie Friederike Warken, Andrea Schrӧder-Ritzrau, Thomas E. Miller, and Denis Scholz
- Seasonal temperature variations control cave ventilation processes in a tropical cave.
- Cave air pCO2 in varies between 600 ppm in winter and 1800 ppm in summer.
- The cave air exchange time is estimated to be 36 ± 5 days.
- Minor pCO2 variations are related to atmospheric pressure changes.
- Cave morphology is a key parameter of ventilation processes.

- The first analysis of antimicrobial activity of bacteria isolated from Krubera-Voronja Cave.
- The first report on chemical characterization of antimicrobial mixtures of Firmicutes isolated from caves.
Hybrid Taguchi-Objective Function optimization approach for automatic cave bird detection from terrestrial laser scanning intensity image
Mohammed O. Idrees and Biswajeet Pradhan
- Developed a hybrid optimization method to detect birds in cave.
- Combined Taguchi's and spatial objective function for cave bird detection.
- Proposed a new semi-automatic counting of birds in cave with greater efficiency.
