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.

Populations of the stygobiotic amphipod Palearcticarellus pusillus (Martynov, 1930) maintain genetic connectivity between the mountain springs and the deep bottom habitats of Lake Teletskoye (Altai Mountains, Russia)
Ivan Marin, Liubov Yanygina, Svetlana Ostroukhova, and Dmitry Palatov

  • A relationship is observed between amphipod populations in mountain springs and deep-sea lakes, possibly due to deep tectonic faults
  • A new version of tiny body size of stygobiotic amphipod is suggested
  • A time calibration for amphipod evolution process in Altai mountain is presented
  • A rare stygobiotic amphipod is re-described
  • A new data on ecology of rare amphipods in Altai Mountains are presented

Time-transgressive microbial diversity in a tropical bat guano accumulation, Deer Cave, Mulu, Borneo
Joyce Lundberg and Donald A. McFarlane

  • Distinctive changes observed in microbiome throughout 120-year old bat guano sequence
  • Diversity is highest in the ecologically-complex surface layer of fresh guano
  • Diversity correlates with acidity, temperature, and depth.
  • In the oldest, most decomposed section of the profile, Actinomycetota dominate
  • Anaerobic H2S-generating surface guano has twice the diversity of aerobic

New ichnofossil discovery in Mallorcan caves: Linking ancient and moden bat-ectoparasites coporolites.
Antonio Merino Juncadella, Joan J. Fornós, Antoni Mulet, and Joaquin Gines

  • Rod-shaped morphologies discovered in Cova des Pas de Vallgornera are described
  • These deposits are interpreted as fossils micro-coprolites of bat ectoparasites
  • The paper is a contribution to the ichnotaxonomy of invertebrate coprolites
  • These morphologies’ abundance could reveal infestation levels in an ancient bat colony

Charlotte: A modern tool for cave surveying
Luca Tringali Mr., Giacomo Canciani Dr., Alexander Debenjak, and Tecla Tripari

  • We developed Charlotte, a new tool for 2.5D cave surveying using modern hardware
  • Charlotte uses LiDAR to measure cave walls, useful for realistic representation
  • We also developed the software to build 3D DXF models from survey data
  • Both Charlotte's hardware and software have been published as open source
  • Charlotte is easy to assemble and cheaper than most commercially available tools
