Fungal Communities On Speleothem Surfaces In Kartchner Caverns, Arizona, Usa., Michael J. Vaughan, Raina M. Maier, Barry M. Pryor

International Journal of Speleology

Kartchner Caverns, located near Benson, Arizona, USA, is an active carbonate cave that serves as the major attraction for Kartchner Caverns State Park. Low-impact development and maintenance have preserved prediscovery macroscopic cavern features and minimized disturbances to biological communities within the cave.. The goal of this study was to examine fungal diversity in Kartchner Caverns on actively-forming speleothem surfaces. Fifteen formations were sampled from five sites across the cave. Richness was assessed using standard culture-based fungal isolation techniques. A culture-independent analysis using denaturing gradient gel electrophoresis (DGGE) was used to assay evidence of community homogeneity across the cave through the …

Revisiting Three Minerals From Cioclovina Cave (Romania), Bogdan P. Onac, Herta S. Effenberger, Nathan C. Collins, Joe B. Kearns, Radu C. Breban

International Journal of Speleology

Cioclovina Cave in Romania’s Southern Carpathians is a world-renowned cave site for its paleontological, anthropological, and mineralogical (type locality of ardealite) findings. To date, over 25 mineral species have been documented, some unusual for a cave environment. This paper presents details on the occurrence of collinsite [Ca₂(Mg,Fe²⁺)(PO₄)₂·2H₂O], atacamite [Cu₂²⁺Cl(OH)₃], and kröhnkite [Na₂Cu²⁺(SO₄)₂·2H₂O] based on single-crystal X-ray diffraction, electron microprobe, stable isotope analyses, and scanning electron microscope imaging. This is the first reported occurrence of kröhnkite …

Secondary Halite Deposits In The Iranian Salt Karst: General Description And Origin, Michal Filippi, Jiří Bruthans, Lukáš Palatinus, Mohammad Zare, Naser Asadi

International Journal of Speleology

This paper summaries 12 years of documentation of secondary halite deposits in the Iranian salt karst.

A variety of secondary halite deposits was distinguished and classified into several groups, on the basis of the site and mechanism of their origin. Deposits formed: i) via crystallization in/on streams and pools, ii) from dripping, splashing and aerosol water, iii) from evaporation of seepage and capillary water, and iv) other types of deposits. The following examples of halite forms were distinguished in each of the above mentioned group: i) euhedral crystals, floating rafts (raft cones), thin brine surface crusts and films; ii) straw …

Minerals And Speleothems Of The József-Hegy Cave (Budapest, Hungary), Szabolcs Leél-Őssy, Gyöngyvér Szanyi, Gergely Surányi

International Journal of Speleology

With the discovery of the József-hegy Cave, a cave of hydrothermal origin with an abundance of minerals unknown so far in Hungary came to light. Diversity and the frequency of the occurrence of crystals make this cave similar to the Lechuguilla Cave, even if the dimensions of the mineral precipitations and the passages do not compare in scale. The variety and mass of carbonates and sulphates are surprising. This paper describes the minerals and speleothems of the József-hegy Cave, their occurrence and genesis, including determined ages. The 41 U/Th measurements suggest that speleothems begun to develop in the upper level …

Educational Evaluation Of Cybersmart Detectives: Final Report: Presented To The Australian Communications And Media Authority (Acma), Julian Dooley, Laura Thomas, Sarah Falconer, Donna Cross, Stacey Waters

Research outputs 2011

The aim of the Australian Communications and Media Authority‟s (ACMA) Cybersmart Detectives (CSD) activity is to teach children key Internet safety messages in a safe school environment. The activity brings together a number of agencies with an interest in promoting online safety for young people, including education, State and Federal Police, government and child welfare advocates. The activity has been played by over 28, 000 students in Australia since initial trials in 2004.

Cybersmart Detectives is offered free to schools by the ACMA as part of the Australian Government‟s commitment to cyber-safety. Based on a real-world Internet safety scenario, the …
