Genesis of iron and manganese sediments in Zoloushka Cave (Ukraine/Moldova) as revealed by δ13C organic carbon
Piotr Kotula, Viacheslav Andreychouk, Jacek Pawlyta, Leszek Marynowski, and Izabela Jendrzejewska

  • Origin of iron and manganese sediments in gypsum cave
  • Isotopic fractionation of biogenic carbon in a cave environment
  • Chemical composition of iron and manganese sediments
  • Variability of carbon isotopic composition in cave air carbon dioxide


Petrography and provenance of floor sediments from the Loutra Almopias Cave (Pella, Macedonia, Greece)
Ioannis Georgiadis, Katerina Chatzopoulou, Nikolaos Kantiranis, Ioakeim Ioakeimidis, and Ananias Tsirambides

  • Channel facies make up the bulk whereas slackwater facies the final layer of the cave sediments.
  • First description of kutnohorite, isomorphous with dolomite, in a Greek cave.
  • Lepus timidus fossils found in the cave represent the southernmost record of this species in Europe


The lampenflora in show caves and its treatment: an emerging ecological problem
Carlos Baquedano Estévez, Luis Moreno Merino, Almudena de la Losa Román, and Juan J. Durán Valsero

  • Artificial lighting causes deterioration of Show Caves due to Lampenflora grow
  • It is not known how to eliminate Lampenflora permanently
  • Chemicals used in cleaning lampenflora can pollute groundwater
  • It is essential to investigate the doses of chemicals used in cleaning lampenflora
  • It appears that an excess of chemicals are used to remove lampenflora


Drivers of ant composition, richness, and trophic guilds in Neotropical iron ore cavities
Rodrigo A. Castro-Souza, Thais G. Pellegrini, Marconi Souza-Silva, and Rodrigo L. Ferreira

  • Ant species richness is higher in the epigean than in the hypogean ferruginous environments
  • Ant species composition is different between epigean and hypogean ferruginous environments
  • The cavity historical use did not influence the ant species richness or composition
  • Subterranean environment traits were not able to explain ant species richness
  • Ant assemblages in the cave communities were mostly composed by generalist species


Screening the cultivable cave microbial mats for the production of antimicrobial compounds and antibiotic resistance
Jerneja Ambrožič Avguštin, Patricia Petrič, and Lejla Pašić

  • We evaluated antibiotic resistance to 22 antibiotics in 69 isolates of cave bacteria
  • Majority (89%) of isolates were resistant to 1-17 antibiotics
  • We screened 78 cave isolates for production of antimicrobials against 10 indicator strains
  • Up to 20.5% of cave isolates inhibited the growth of indicator strains
  • Isolates most frequently inhibited growth of methicillin resistant Staphylococcus spp.

Rapid Communication


Barite replacement boxwork in the Frasassi caves (Italy)
Sandro Galdenzi

  • Barite boxwork replacing the spar veins of limestone in the cave environment
  • Replacement process related to sulfide oxidation in a sulphuric acid cave
  • Replacement process related to corrosional rills produced by rising fluids in the groundwater
  • Co-existence of corrosional and encrusting processes in the groundwater
