Increased cave use by butterflies and moths: a response to climate warming?
Otto Moog, Erhard Christian, and Rudolf Eis

  • The number of lepidopteran species from Austrian caves sharply increased since 2015
  • Most of the newly recorded species visit cave mouths by day in the warm season
  • Climate warming makes a cave stay on hot summer days more attractive to Lepidoptera
  • The inclination to use caves as diurnal retreats can differ between related species


Hydrometeorological factors determining the development of water table cave patterns in high alpine zones. The Ordesa and Monte Perdido National Park, NE Spain
Antonio González-Ramón, Jorge Jódar, José M. Samsó, Sergio Martos-Rosillo, Javier Heredia, Ane Zabaleta, Iñaki Antigüedad, Emilio Custodio, and Luis J. Lambán

  • The recharge of karst aquifers in high mountain may be controlled by snowmelt
  • Water-table caves exist in permeable carbonates with irregular recharge and no developed epikarst
  • Diffuse recharge caused by snow in cold areas may explain the unusual water-table caves patterns
  • Repetition of structures by faults and thrusts can generate repetitive patterns in karst networks
  • Conduit set connects consecutive perched saturated zones in the inner part of syncline structures


Safe and effective disinfection of show cave infrastructure in a time of COVID-19
Hazel A. Barton

  • Showcaves have unique challenges to coronavirus disinfection
  • The chemistry of coronaviruses suggest they will adsorb to limestone
  • The chemistry of limestone surfaces is likely to inactivate coronaviruses
  • Effective disinfectants with minimal impact on caves were identified
  • Face masks and social distancing remain critical in preventing disease


A world review of fungi, yeasts, and slime molds in caves
Karen J. Vanderwolf, David Malloch, Donald F. McAlpine, and Graham J. Forbes


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
