“…CONAMA -Conselho Nacional do Meio Ambiente, 2004) -and even to the provisional tourist carrying capacity of the cave, based on the method of Lobo et al (2013). Cave atmosphere studies have also contributed, however with a difference: air temperature, relative humidity and CO 2 concentration can respond to the presence of visitors in confined places (Calaforra et al, 2003;Cigna, 2002;Fernández-Cortés et al, 2006b). Therefore, the responses were registered and analyzed based on the inputs from the pilot tests.…”

Tourist Traffic Significantly Affects Microbial Communities of Sandstone Cave Sediments in the Protected Landscape Area “Labské Pískovce” (Czech Republic): Implications for Regulatory Measures

Abstract:In the Protected Landscape Area "Labské pískovce" (Czech Republic), there are many sandstone caves accessible by permission only and where climbing equipment is commonly required. The tradition of visiting the caves dates back to turn of the 19th and 20th centuries, and visitors traditionally record their visits in log-books. We have gathered attendance data from 12 caves from log-books and via survey (2-year form collection period). The attendance varied from less than 10 to~650 visitors annually. Signs of inadequate behavior of visitors were observed, especially waste disposal and smoking in the caves. Sediment step-compression increased significantly the ratios of fungi/bacteria and gram-positive to gram-negative (G+/G−) phospholipid fatty acids (PLFA) as well as PLFA of actinobacteria and activities of sediment phosphatases, glucosidases, and peroxidases. The number of visitors was correlated positively with the G+/G− ratio and sediment nutrients but negatively with sediment moisture and the activity of peroxidases. The results indicate a significant effect of attendance on sediment microbial communities, most likely caused by the import of nutrients into caves. Hence, reconsideration of the cave attendance policy is recommended.

“…Despite the growing number of monitoring campaigns, there is no unique 'white paper' prescribing the directives. Some of the general recommendations regarding overall monitoring are provided in Toomey (2009), Cigna (2002 proposes detailed instructions and offers some solutions of possible problems, while techniques and sensitivity/precision of measurements are compiled in Fairchild and Baker (2012, and references therein). On the other hand, some authorities (e.g.…”

IzvlečekUDK 551.435.84(497.5) Maša Surić: Izzivi monitoringa in vzorčenja v kraških jamah -izkušnje pri raziskavah sig na Hrvaškem Z namenom rekonstrukcije kvartarnega okolja v Dinarskem krasu že več let raziskujemo sige iz hrvaških kraških jam. Ker je interpretacija zapisov paleo-okolja v sigah močno odvisna od dobrega poznavanja in razumevanja procesov, ki povezujejo atmosfero, hidrologijo in sige, je zelo pomemben tudi monitoring recentnega jamskega okolja. čeprav so postopki vzorčenja in meritev relativno preprosti, pri delu vseeno srečujemo številne probleme, povezane z naravnimi in tehničnimi vzroki. Izjemne vremenske razmere, kot so intenzivne padavine, suša in sneg, lahko povzročijo izgube vzorcev. Po drugi strani zaradi tehničnih izpadov delovanja opreme izgubljamo pridobljene podatke. Redkeje, a vseeno, lahko pridobivanje vzorcev in podatkov ogrozijo tudi jamske živali. čeprav vseh teh pojavov ne moremo izključiti, lahko njihove negativne vplive minimiziramo, tehnične težave pa v veliki meri rešimo. V članku predstavimo težave in njihovo reševanje pri raziskavah v hrvaških jamah. Ključne besede: jama, kras, jamski monitoring, vzorčenje, Hrvaška. Speleothem-based research aimed at the reconstruction of the quaternary environment in Dinaric karst has been conducted in several Croatian caves. As the interpretation of the palaeoenvironmental signal archived in speleothems relies on identifying and understanding processes between atmosphere and cave precipitates, especially hydrological behaviour, cave monitoring is crucial. Despite relatively simple sampling and monitoring protocols, series of problems and complications has arisen, caused by different natural and technical reasons. Extreme weather events such as enormous precipitation, prolonged drought or snow drifts, each in their own way can cause sample loss. On the other hand, technical issues associated with equipment failures can lead to irretrievable data loss, and even biological threats, both man-induced and of natural origin, can occur. Although the later cannot be eliminated, as well as extreme weather, gained experience substantially helps to minimize negative effects. On the other hand, most of the technical issues are resolvable, and suggested solutions have been regularly implemented.
