Data on the Algal Flora of Kolyuk cave close to Manfa (Hungary)., 1965,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/speleogenesis.info/include/functions1.php on line 943

The Kolyuk cave lies in the southern part of Hungary in the Mecsek Mountains, about 3 km. in distance from the village of Mnfa. The material accepted for investigation originated from a recently discovered and until now completely entombed part of the cave. It was collected by the geologist Gbor Magyari and consisted of material scraped from the walls and ceiling of a cavity in the cave, which could be reached only by underwater swimming. From these scrapings cultures were installed with sterile Knopp solution and after the algae present in the collection reproduced, a diversified flora developed which consisted of the following: Cyanophyta; 20 species, varietates and formae; Bacillariophyta; 2 species and varietas; Chlorophyta; 7 species. There was a total of 29 different taxa. Since the cave from which the collections were made was completely devoid of light, it is especially significant that a well developed blue-green algal flora was found. We thus have further evidence for our previously advanced theory (Claus, 1955, 1962 a, 1962b) that some algae were present in the caves at the time of their origin. They were able to survive in an actively assimilating vegetative state and not only in the form of cysts or arthrospores.

Lecania pusilla Tretiach sp. nov. is described from the Trieste Karst, where it was collected twice on epilithic mosses in protected overhangs. The new species is characterized by simple or uniseptate spores, pruinose apothecia, and Bacidia-type asci; it has a reduced, granular thallus with no lichen substances.

Palynological evidence for Mesozoic karst at Piltown, Co. Kilkenny, 2000,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/speleogenesis.info/include/functions1.php on line 943
Higgs K. T. , Jones G. L. ,
Exploration drilling by Pasminco Australia Ltd. in 1993 at Piltown near Carrick-on-Suir. encountered brown. yellow and fawn clays of the Piltown Clay Formation (new name) lying on and in Carboniferous limestone. Palynological analysis of these clays indicates that they are late Jurassic to early Cretaceous in age. The palynomorphs are well preserved but not abundant. They consist mostly of terrestrially derived spores and pollen grains, though the rare occurrence of dinoflagellate cysts indicates a weak marine influence in some of the sediments. The presence of these Mesozoic sediments within karstified limestone implies an active karat system before and/or during late Jurassic-early Cretaceous times in south County Kilkenny

Pennsylvanian paleokarst and cave fills from northern Illinois, USA: a window into Late Carboniferous environments and landscapes, 2009,

A new fault-associated paleokarst and cave fill has been discovered in north-central Illinois, emplaced in Ordovician limestones. The palcokarst preserves many original solution features, such as oriented grooves, pendants, and half tubes. Many of the ancient cave passages have rounded bottoms and flat roofs. Together these suggest that the original elliptical, phreatic cave passages grew upward by paragenesis, in which the floor of the cave is protected from dissolution by the presence of sediment, while the ceiling of the cave grows upward by dissolution. The fill is dated as Moscovian (Middle Pennsylvanian) based on palynological data and can be correlated with the Tradewater Formation. The fills are composed of a fining-upward sequence of relatively unindurated elastic sediments that contain well-preserved plant fossils, most notably voltzialean conifer and cordaite remains, representative of vegetation living in well-drained areas. Many of the macrofossils are fragmentary but charcoalified and, along with the megaspores, are uncompressed and preserve exceptional morphological and anatomical data. The presence of abundant charcoal in the fills, as well as diagnostic polycyclic aromatic hydrocarbons, indicates significant wildfire activity in this area during this interval.


Evaluation of Strategies for the Decontamination of equipment for Geomyces destructans, the Causative Agent of the White-Nose Syndrome (WNS), 2013,

White-nose syndrome is an emerging infectious disease that has led to a
dramatic decline in cave-hibernating bat species. White-nose syndrome is caused by the
newly described fungal pathogen Geomyces destructans, which infects the ear, muzzle,
and wing membranes of bats. Although the exact mechanism by which the fungus causes
death is not yet understood, G. destructans leads to a high mortality rate in infected
animals.While the primary mechanism of infection appears to be bat-to-bat transfer, it is
still unclear what role human activity may play in the spread of this pathogen. Here we
evaluate the effectiveness of decontamination protocols that can be utilized by
speleologists to reduce the likelihood of spreading this dangerous pathogen to naı¨ve
bats or uninfected hibernacula. Our results show that pre-cleaning to remove muds and/
or sediments followed by the use of commercially available disinfectants can effectively
remove G. destructans from caving fabrics. Alternatively, immersion in water above
50 uC for at least 20 minutes effectively destroys the fungal spores. These results have
allowed the development of a decontamination protocol (http://www.fws.gov/
WhiteNoseSyndrome/cavers.html) that, when appropriately followed, can greatly
reduce the likelihood of the human mediated transfer of G. destructans from an
infected to uninfected site.
