Die Slowakischen Shauhöhlen Und Ihre Probleme, Ivan Racko
Die Slowakischen Shauhöhlen Und Ihre Probleme, Ivan Racko
International Journal of Speleology
In 1960 the Slovak Caves Administration, which managed twelve Slovak Caves was founded. It was controlled by the Ministry of Culture of the Slovak Socialist Republic and comprised also the Museum of Slovak Karst and the Slovak Speleological Society - a free speleological organisation. In 1981 such an Administration became part of the State Centre for the Protection of Nature. The main task of this centre was obviously the protection of nature in Slovakia but unfortunately many problems remained unsolved. The social movement in November 1989 accelerated the process to solve such problems and the Forum of Professional Workers of …

Problems Of Show Caves In Bohemia And Moravia, Milka Dusan
Problems Of Show Caves In Bohemia And Moravia, Milka Dusan
International Journal of Speleology
In the last years the show caves in Bohemia and Moravia were administrated by the Ministry of Culture with the status of a state assisted organization. That means that they were considered as those organizations not self-sufficient, without connections with tourism. Presently, the management of the show caves in Bohemia and Moravia is at a crossroad: to remain under the administration of the Ministry of Culture or move under the newly formed Ministry of Environment. In the latter case the cave management should change into a business organization similar to a private body. We believe that these problems can be …
Problemi Turistici Della Grotta Gigante Nel Carso Triestino, Fabio Forti
Problemi Turistici Della Grotta Gigante Nel Carso Triestino, Fabio Forti
International Journal of Speleology
The paper reports the tourist evolution of the Grotta Gigante (Giant Cave), near Trieste (Italy) during 80 years (1908 - 1989) of its opening to the public. At the beginning it entered in competition with some other local show caves, even much more famous (like Postojna and Stocjan), after the II World War on account of the change of the state boundaries it remained the sole show cave in that part of Italy. Then the Grotta Gigante succeeded, even if slowly, to cope with the changing tourist demands, improving more and more its facilities to follow the increasing tourist flows. …
Die Saalfelder Feengrotten: Ein Schaubergwerk Mit Höhlencharkter, Bernd Lochner
Die Saalfelder Feengrotten: Ein Schaubergwerk Mit Höhlencharkter, Bernd Lochner
International Journal of Speleology
The well known “Saalfelder Feengrotten” originated from an old aluminium mine called “Jeremiasglück”. The mine has been working from 1943 to 1945; the oldest formations have an age of about 350 years. Such formations were formed by an oxidation process which explains the rather fast growth rate in comparison to the growth rate of calcite formations. In the “Feengrotten” rare minerals can be found: the most common is a soft unstable compound, the diadochite (iron(III) phosphate). The control of the lampenflora is rather complicate and it is obtained with some compounds normally used in caves. The “Feengrotten” are visited yearly …
La Cueva Del Tesoro - Rincón De La Victoria (Málaga, España), Antonio Guzmán, Fernando Mendoza, José Luís Gutiérrez
La Cueva Del Tesoro - Rincón De La Victoria (Málaga, España), Antonio Guzmán, Fernando Mendoza, José Luís Gutiérrez
International Journal of Speleology
«La Cueva del Tesoro» (The Treasure Cave) is located on the East, 10 kilometres from the city of Málaga, in a coastal promontory called «El Cantal» (a small steep), which is situated in the municipality of Rincón de la Victoria. The composition of land in this zone «El Cantal» is made up of limestone and there are many caves which are located within a radius of 2 kilometres, although some of them have already disappeared: la Cueva del Tesoro, la cueva del Hoyo de la Mina, Cuevas de Navarro, Cuevas de la Cantera, Cueva de los Molinos, Cueva de la …

Life Cycle And Population Ecology Of The Cave Cricket Dolichopoda Geniculata (Costa) From Valmarino Cave (Central Italy), Glanmaria Carchini, Mauro Rampini, Valerio Sbordoni
Life Cycle And Population Ecology Of The Cave Cricket Dolichopoda Geniculata (Costa) From Valmarino Cave (Central Italy), Glanmaria Carchini, Mauro Rampini, Valerio Sbordoni
International Journal of Speleology
A D. geniculata population inhabiting a natural cave at low altitude near seashore was followed during two years. The population size, distribution in three age classes, spatial distribution, feeding habits were recorded. The life-cycle was found semivoltine, with overlaps between next choorts in each age class. A comparison to other Dolichopoda showed that the population of Valmarino cave is one of the best adapted to cave life, and this may be related with both historical and present geographical and ecological conditions of the cave.

Some Remarks On The Genus Microcharon Karaman In Greece, And Description Of M. Agripensis N. Sp. (Crustacea, Isopoda, Microparasellidae), Diana M. P. Galassi, Paola De Laurentiis, Giuseppe L. Pesce
International Journal of Speleology
Several samples of microparasellid isopods of the genus Microcharon Karaman were obtained in groundwater habitats of Greece. Four species are identified, and taxonomical and zoogeographical remarks on some rare or poorly known taxa are made. One species, herein described as Microcharon agripensis n. sp., is new to Science. M. latus prespensis Karaman, 1954, on account of the different morphology of the first and second male pleopods, and its partially overlapping distribution, in respect to M. latus Karaman, 1934, is definitively raised at specific rank. Supplementary descriptions and illustrations are reported for incompletely described species such as M. latus, M. …
Sinogammarus Troglodytes N. Gen. N. Sp. A New Troglobiont Gammarid From China (Crustacea Amphipoda), Gordon Karaman, Sandro Ruffo
Sinogammarus Troglodytes N. Gen. N. Sp. A New Troglobiont Gammarid From China (Crustacea Amphipoda), Gordon Karaman, Sandro Ruffo
International Journal of Speleology
The authors describe Sinogammarus troglodytes n. gen. n. sp. found in two caves in Sichuan province in China, the first Chinese troglobite of the Gammaridae family (sensu Barnard & Barnard, 1983; 1990). The new genus is discussed and compared with the microphthalmous and anophthalmous genera of Gammaridae, heretofore known in the subterranean waters of the Balkan peninsula and the Caucasus region. The genus Sinogammarus is most closely allied to Gammarus Fabricius and Anopogammarus Derzhavin.
A New Jujiroa From Sichuan, China (Coleoptera, Carabidae), Augusto Vigna Taglianti
A New Jujiroa From Sichuan, China (Coleoptera, Carabidae), Augusto Vigna Taglianti
International Journal of Speleology
Jujiroa iolandae n.sp. is described from Liujia Cave in China (Sichuan, near Huaying, between Chongqing and Nanchong). Strongly depigmented, with very reduced eyes and markedly elongated appendages, it is well distinguishable from Taiwanese and Japanese species, and from the two previously known species from China. One of these, J. suensoni from Shangxi, is quite different (its doubtful taxonomic position is perhaps to be referred to another genus or lineage); the other, J. rufescens from Jiangxi (Fujian), is more related to the new species, that differs by the longer and more sinuate pronotum, with fore and hind angles much more produced, …
Towards Regressive Evolution: The Periodic Colour Change Behaviour Of A Troglophilic Fish Nemacheilus Evezardi (Day), Rohit K. Pradhan, Jayant Biswas
Towards Regressive Evolution: The Periodic Colour Change Behaviour Of A Troglophilic Fish Nemacheilus Evezardi (Day), Rohit K. Pradhan, Jayant Biswas
International Journal of Speleology
Present study is an attempt to know the existence of colour change physiology of the cave fish Nemacheilus evezardi (Day) along a circadian time scale. Though, due to subterranean mode of life, practically this function has no survival value. The study has been conducted simultaneously in two different photoperiodic conditions (LD 00: 24 and LD 12:12 hr). The variation in different states of chromatophore has been computed with respect to different time points of the day. Results suggest that the phenomenon is lying completely disturbed in its in situ conditions. Interestingly, circadian rhythm in all the types of chromatophores were …
Management Of Some Unusual Features In The Show Caves Of The United States, Jeanne Gurnee
Management Of Some Unusual Features In The Show Caves Of The United States, Jeanne Gurnee
International Journal of Speleology
Protection of the unusual features in some of the 200 show caves of the U.S. have required innovative management. The sea caves of both the east and west coasts present the need for special preservation methods. Throughout the nation sometimes glass enclosures, vehicles and boats are used to separate visitors from sensitive cave features. Lighting and cleaning techniques have been studied and altered to discourage growth of algae. Some show caves are protected by double glass entrance and exit doors. Many caves, particularly on public lands, are closed during the hibernation period of endangered bats. In a number of caves, …
230Th Dating Of The Speleothems From The "Grotta Del Fiume-Grotta Grande Del Vento" Karst System In Frasassi (Ancona, Italy) And Paleoenvironmental Implications, Adriano Taddeucci, Paola Tuccimei, Mario Voltaggio
230Th Dating Of The Speleothems From The "Grotta Del Fiume-Grotta Grande Del Vento" Karst System In Frasassi (Ancona, Italy) And Paleoenvironmental Implications, Adriano Taddeucci, Paola Tuccimei, Mario Voltaggio
International Journal of Speleology
Chronological measurements have been carried out on speleothems from the Grotta del Fiume-Grotta Grande del Vento karst system in Frasassi (Ancona, Italy) by means of the 230Th radiometric method in order to date hypogean karst levels and related geological events. Higher levels were found to be older than the lower ones according to standstills and sinkings of the water table. The dated speleothems from the first and second level formed less than 10,000 years ago; the minimum ages of the third and fifth levels, which are respectively 130,000 and 200,000 years old, were correlated to climatic events. Dating different …

Activity Of The Scientific Commission Of "Grotta Grande Del Vento" (Genga, Ancona, Central Italy), Mario Bertolani, Arrigo A. Cigna
International Journal of Speleology
The Grotta Grande del Vento (the Great Wind Cave) was discovered in 1971. An administrative body (the “Consorzio Frasassi”) under the control of some local authorities took care of its development and the cave was opened to tourists in 1974. A Scientific Commission formed by some experts (choosen by the Consorzio Frasassi) of different disciplines was established in 1975. During these 15 years the Commission acted as an advisory committee for the Consorzio in order to guarantee the protection of the cave environment. In particular the Commission set up a monitoring network of the most important environmental parameters (air and …

Faunistic Study In The Karst Complex Of Frasassi (Genga, Italy), Roberto Bertolani, Gian Carlo Manicardi, Lorena Rebecchi
International Journal of Speleology
The cave fauna of the karst complex of Frasassi (Genga. Ancona, Italy), which includes a tourist attraction, was surveyed to provide detailed information on the hypogean animal populations. Indeed, for this area, only sporadic and limited studies are known in the literature to date. The bat populations, recently analyzed by Bassi and Fabbri (1986-87), were excluded from our study. Ten collection campaigns were carried out in 12 different caves, including the tourist site, over a span of two years. Three caves were considered in all the collections and the others only on one or two occasions. The animals were captured …
Proposition Pour Une Étude Micro-Climatique En Zones Souterraines Profondes, Jacques Choppy, Arrigo A. Cigna
Proposition Pour Une Étude Micro-Climatique En Zones Souterraines Profondes, Jacques Choppy, Arrigo A. Cigna
International Journal of Speleology
Deep underground zones of karst systems are practically isolated from the outside influence and their climatological characteristics are scarcely known. To improve the knowledge of the karst areas it would be therefore rather useful to obtain energy balances for different environmental situations in order to evaluate both the deep climatological phenomena and the outside influence.

La Grotta Del Vento: Una Realta'nel Contesto Del Parco Naturale Delle Alpi Apuane, Vittorio Verole-Bozzello
International Journal of Speleology
After a short history of the explorations of the cave its development as a show cave is here reported with details. Such a development was carried out in order to preserve not only the physical integrity of the cave environment but also to keep the tourists’ approach as natural as possible. In co-operation with the Medical Faculty of the Pisa University the cave is also used since many years for an interesting and quite successful experiment for the treatment of bronchial asthma.
