Interesting records of microscopic fungi
Nováková, Alena
Six saprotrophic microfungi were presented in this paper - they were isolated during the study of micromycetes from cave systems of the Czech Republic, Slovakia and Romania and from soils of post-mining areas in the U.S.A. Their occurrence and morphology were compared with literature records.

Does .i.Histoplasma capsulatum./i. occur in caves of middle Europe?
Nováková, Alena ; Chroňáková, Alica
During studies of micromycetes in several caves (Slovakia - NP Slovak Karst, Czech Republic), white-yellow to yellow coloured microfungal colonies on bat droppings are observed. Tuberculate conidia were estimated in microscopic slides prepared from these colonies. These conidia reminded with their size, shape, surface structures and type of conidiogenesis pathogenous micromycete fungus .i.Histoplasma capsulatum./i.. This micromycete species occurs on bat guano in warmer regions of the world. In Europe, this fungus was recorded from Italian caves and soils and it was also reported from Romania, but without the evidence of thermal dimorphism. After repeteadly isolations, two strains of this fungus were isolated from Slovak caves (Domica Cave and Jasovská Cave). Tests of pathogenity (intranasal and intraperitoneal application to SCID mouses) and of the evidence of thermal dimorphism were negative.

Výzkum sedimentárních výplní vybraných jeskyní na Slovensku
Bosák, Pavel ; Pruner, Petr ; Bella, P. ; Hercman, H. ; Hochmuth, Z. ; Kicinska, D. ; Šlechta, Stanislav ; Schnabl, Petr
Pokračující paleomagnetický výzkum sedimentárních profilů vybraných jeskyní na Slovensku doplnil významné předběžné výsledky předchozího výzkumu, které mnohdy změnily dosavadní představy o časovém zařazení speleogenetického procesu, etapovitosti vývoje jeskynních soustav a rozvoje reliéfu a říčních terasových systémů na Slovensku, jakož i vazeb jeskynních úrovní na v současnosti zachované morfologické tvary. Výsledky výzkumů byly publikovány v předběžných sděleních a původních pracích.

Potravní zdroje bezobratlých v Ardovské jeskyni a v jeskyni Domica - předběžné výsledky
Nováková, Alena ; Elhottová, Dana ; Krištůfek, Václav ; Lukešová, Alena ; Hill, P. ; Kováč, L. ; Mock, A. ; Luptáčik, P.
The chemistry (organic matter content and pH) of different substrates from the Ardovská and Domica Caves in the Slovak Karst National Park (Slovakia) and the composition of their microbial communities were studied. Differences in organic matter content and microbial communities were found between the substrates from the Domica and Ardovská Caves. A broad spectrum of photoautotrophic microorganisms (algae and cyanobacteria) was found in different cave microhabitats (cave sediment, rotten wood, earthworms casts and isopods faeces), but no algae were detected in the fresh bat droppings and in the intestinal tract of the isopod .i.M. graniger./i.. Microfungi and bacterial colonies play the primary role in transforming bat guano into a food source for saprophagous and microphytophagous invertebrates.

Zajímavé a vzácné saprotrofní mikroskopické houby z exkrementů a ostatních substrátů jeskyně Domica a Ardovské jeskyně (NP Slovenský kras, Slovensko)
Nováková, Alena
A broad spectrum of saprotrophic microfungi representing possible food sources for cave invertebrates was isolated from different substrata (invertebrates, bat and marten excrements, bat guano, cave sediment, air) from the Domica and Ardovská Caves. .i.Pidoplitchkoviella terricola./i. and .i.Thielavia hyrcaniae./i. are rather rarely isolated micromycetes. The species interesting from the point of view of the colony appearance or microscopic properties were .i.Penicillium glandicola, Beauveria brongniartii, Chaetomium indicum, Penicillium hirsutum, Penicillium hordei, Rhinocladiella./i. sp., .i.Aspergillus versicolor, Echinobotryum./i. state of .i.Doratomyces stemonitis./i., and .i.Oidiodendron cerealis./i..

Speleoarchaeology between the Karst and Pseudokarst
Svoboda, Jiří
This paper introduces two current projects dealing with prehistoric occupation of the karstic and pseudokarstic (sandstone) areas of the Czech Republic. The largest sets of (calibrated) C14 data are available for the Magdalenian and Mesolithic periods. Spatially, emphasis is concetrated on studies of the karstic and pseudokarstic areas as settlement systems. Additionally, this paper resumes the problems of methodology, interdisciplinary collaboration, and site protection.

Potential of the Czech Republic as a destination for speleotourism
Jarošová, Petra ; Petrů, Zdenka (advisor) ; Valentová, Jana (referee)
The thesis is focused on possibilities of using caves for the purpose of tourism and for spending free time. Particular goal, as the title of the thesis discovers, is to measure the potential of the Czech Republic as a destination for speleotourism. The thesis charts and analyses recent supply of speleologic free time activities for the general public and maps over activity of organizations involved in caves exploring and protecting. The thesis points out obstacles in developing speleotourism and also sketches out possible future progress; based on discussions with members of the Czech Speleological Society and other authorities.
