SPECIAL ISSUE dedicated to the International Year of Caves and Karst (IYCK)

On this occasion, the International Journal of Speleology (IJS) is preparing a Special Issue that will consider manuscripts representing new advances and provide insights into and address challenges in all fields of cave and karst research topics. We especially encourage cross-disciplinary contributions. The full papers must be submitted through IJS portal. When submitting your paper, be sure to select from the Document type dropdown menu, the IYCK 2021 Special Issue. Please see Submission Guidelines on the journal’s website.

The deadline for submission is October 15, 2020.

The International Journal of Speleology is the official journal of the Union Internationale de Spéléologie since 1978 and was founded in 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, archeology, paleontology, (paleo)climatology, cave meteorology, (geo)microbiology, environmental sciences, physics, chemistry, mineralogy, etc. IJS is published three times per year.

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.

Bubble trail and folia in cenote Zapote, Mexico: petrographic evidence for abiotic precipitation driven by CO2 degassing below the water table
Rafael López-Martínez, Fernando Gázquez, José M. Calaforra, Philippe Audra, Jean Y. Bigot, Teresa Pi Puig, Rocío J. Alcántara-Hernández, Ángel Navarro, Philippe Crochet, Liliana Corona Martínez, and Raquel Daza Brunet

  • The origin of folia is still controversial
  • In the Cenote Zapote occurs the biggest reported folia
  • Folia are the result of subaqueous calcite precipitation around CO2 bubbles


Stratigraphical influence on chalk cave development in Upper Normandy, France: implications for chalk hydrogeology
Daniel Ballesteros, Andrew Farrant, Carole Nehme, Mark Woods, Dominique Todisco, and Damase Mouralis

  • The role of stratigraphic discontinuities on chalk speleogenesis has been analyzed
  • The analyses combine cave geometry, karst geomorphology and stratigraphical sections
  • Chalk caves and karst springs are related to hardgrounds, sheet-flints and marl beds
  • Hardgrounds, sheet-flints and marl beds concentrated groundwater flow forming caves
  • The results reinforce the visualization of the Chalk as a karst aquifer


The impact of sample processing and media chemistry on the culturable diversity of bacteria isolated from a cave
Katey E. Bender, Katelyn Glover, Alexander Archey, and Hazel A. Barton

  • A “culturomics” cultivation study was performed in a cave for the first time
  • Cultivation strategies were assessed for their performance with cave microbes
  • Sample suspension buffer had no effect on culturability
  • Including antibiotics in culture media decreased apparent culturability, diversity
  • Antibiotics enriched rarer slow-growing species that are more difficult to isolate


Distribution of crickets (Subfamily: Phalangopsinae) in caves of Baratang Island, Andaman and Nicobar Islands, India
Amruta Dhamorikar, Dhanusha Kawalkar, and Shirish Manchi

  • Cricket occupancy in the caves is seasonal and zonal with detectability ≤1
  • Relative density and relative abundance does not vary between the caves zones
  • Morphology of the caves influence the abundance and density of crickets
  • Cave with plausible source population with no extinction probability is identified
  • Further studies recommended for the conservation of caves and cave fauna


Urine volume reduction during long-duration cave exploration by a light-weight and portable forward osmosis system
Sebastian Engelhardt, Katey E. Bender, Jörg Vogel, Stephen E. Duirk, Francisco B. Moore, and Hazel A. Barton

  • Forward osmosis (FO) was tested as a strategy for urine mitigation during cave exploration
  • Urea rejection was determined for a novel aquaporin-based membrane (ABM) module
  • A light-weight and portable FO prototype was introduced and tested
  • Urine volume could be reduced by over 80% using the proposed system
  • Draw solution recovery without nitrogen loss could be achieved by evaporation
