Cosmogenic Nuclide Dating Of Cave Sediments In The Eastern Alps And Implications For Erosion Rates, Philipp Häuselmann, Lukas Plan, Peter Pointner, Markus Fiebig
Cosmogenic Nuclide Dating Of Cave Sediments In The Eastern Alps And Implications For Erosion Rates, Philipp Häuselmann, Lukas Plan, Peter Pointner, Markus Fiebig

Karstic caves are created by water eroding and corroding rocks that can be dissolved. Since both the spring areas of caves (normally at the valley bottom) as well as the recharge is controlled by superficial processes, the morphology of the cave bears strong links to these influences. Lowering of local base levels promotes the development of horizontal phreatic cave passages at progressively lower elevations, resulting in the formation of multi-level karst systems. Upon the next lowering of base level, these upper systems become fossilized, and sediment trapped within them may remain preserved for millions of years. Dating these sediments gives …
Safe And Effective Disinfection Of Show Cave Infrastructure In A Time Of Covid-19, Hazel A. Barton
Safe And Effective Disinfection Of Show Cave Infrastructure In A Time Of Covid-19, Hazel A. Barton
International Journal of Speleology
The COVID-19 pandemic, caused by the novel coronavirus SARS-CoV-2, has been responsible for over 650,000 deaths worldwide. Transmission of SARS-CoV-2 occurs primarily through airborne transmission or direct human contact, demonstrating the importance of social distancing measures and the use of face masks to prevent infection. Nonetheless, the persistence of coronavirus on surfaces means that disinfection is important to limit the possibility of contact transmission. In this paper, the potential for various surfaces in show caves to serve as sources for SARS-CoV-2 infection is examined. Given the isoelectric potential (pI) of SARS and SARS-like coronaviruses, it is likely that they are …

Survey Of Histoplasma Capsulatum In Bat Guano And Status Of Histoplasmosis In Slovenia, Central Europe, Janez Mulec, Saša Simčič, Tadeja Kotar, Romina Kofol, Sanja Stopinšek

There have been increasing reports on the presence of Histoplasma capsulatum in some European countries. The study investigated the presence of Histoplasma in bat guanos, speleologists with records of visiting Histoplasma-endemic regions and patients with histoplasmosis. A commercial ALPHA Histoplasma Antigen enzyme immunoassay was tested as an alternative methodology to detect Histoplasma in environment and compared with polymerase chain reaction (PCR) assays. The presence of Histoplasma antigen in bat guanos was not confirmed by PCR. Among 14 healthy speleologists, two were indicated as having the Histoplasma antigen in urine, but expressed negative PCR-specific results for the Histoplasma antigen. Five …
