Cosmogenic nuclide dating of cave sediments in the Eastern Alps and implications for erosion rates
Philipp Häuselmann, Lukas Plan, Peter Pointner, and Markus Fiebig

  • Dating of caves in the Northern Calcareous Alps gives absolute ages
  • Ages can be used to retrace valley erosion rates
  • Valley erosion rates are compared with other data throughout the Alps
  • Erosion rates are slower in Mio-Pliocene and accelerate in Quaternary

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

Did you wash your caving suit? Cavers’ role in the potential spread of Pseudogymnoascus destructans, the causative agent of White-Nose Disease
Violeta Zhelyazkova, Antonia Hubancheva, Georgi Radoslavov, Nia Toshkova, and Sebastien J. Puechmaille

  • The fungus Pseudogymnoascus destructans (Pd) is a deadly pathogen for bats
  • Pd spores can be present on caving equipment following a visit to a cave
  • Pd spores can survive on caving equipment for at least 25 days, and probably longer
  • Regular washing removes most Pd spores although it does not replace decontamination
  • Worldwide measures to reduce anthropogenic pathogen pollution in caves are needed

The role of microhabitats in structuring cave invertebrate communities in Guatemala
Gabrielle S.M. Pacheco, Marconi Souza Silva, Enio Cano, and Rodrigo L. Ferreira

  • Troglobitic species responded to different substrate features than non-troglobitic species
  • The high specialization of troglobitic species might explain such different responses
  • The findings of this study give insights on how biodiversity is distributed within a cave
  • Conservation measures should aim to preserve as many microhabitats and trophic resources as possible
