The Nitrogen Dynamics Of Deer Cave, Sarawak, And The Role Of Bat Caves As Biogeochemical Sinks In Tropical Moist Forests., Joyce Lundberg, Donald A. Mcfarlane, Guy Van Rentergem
International Journal of Speleology
A better understanding of the role of bat caves as nitrogen sinks in tropical moist forest ecosystems can be expected to shed light on regional and spatial variability in nutrient recycling studies. We measured the nitrogen flux (in air and water) associated with a very large Chaerephon plicata bat colony in Deer Cave, Borneo, in the process generating a new, quantitative, estimate of the total bat population (774,828 ±48,320), and the first detailed modelling of an ammonia plume in a cave. Long-term storage of N does not occur in this wet cave. Our final budget numbers indicate that, of the …

White-Nose Disease (WND) has killed millions of hibernating bats in the US and Canada. Its causative agent, the fungus Pseudogymnoascus destructans was introduced to North America, but is native to Europe and Asia, where it is not associated with mass mortality. Although it is nearly impossible to eradicate an emerging wildlife disease, research on P. destructans spread mechanisms can aid in prevention of new introductions and development of better environmental management strategies. It is of particular importance to quantify the potential role of people visiting caves (cavers, tourists, bat researchers, etc.) whom inadvertently move P. destructans spores between sites, and …
Are Microclimate Conditions In El Malpais National Monument Caves In New Mexico, Usa Suitable For Pseudogymnoascus Growth?, Terry J. Torres-Cruz, Andrea Porras-Alfaro, Nicole A. Caimi, Ogochukwu Nwabologu, Edward W. Strach, Kaitlyn J.H. Read, Jesse M. Young, Debbie C. Buecher, Diana E. Northup

White-nose syndrome (WNS) is a bat disease caused by the fungal pathogen Pseudogymnoascus destructans, which thrives in cold and very humid environments where bats frequently hibernate. Conidia of Pseudogymnoascus species are often documented on bats prior to the onset of WNS, but characterization of high-risk areas defined by microclimate cave conditions have been lacking. Investigating the occurrence of this fungal genus and appropriate environmental conditions to support P. destructans in southwestern U.S. caves is key to understanding the sites most likely to be impacted by WNS. Microclimate conditions in ten caves at El Malpais (ELMA) National Monument in New …
Fungi On White-Nose Infected Bats (Myotis Spp.) In Eastern Canada Show No Decline In Diversity Associated With Pseudogymnoascus Destructans (Ascomycota: Pseudeurotiaceae), Karen J. Vanderwolf, David Malloch, Donald F. Mcalpine
Fungi On White-Nose Infected Bats (Myotis Spp.) In Eastern Canada Show No Decline In Diversity Associated With Pseudogymnoascus Destructans (Ascomycota: Pseudeurotiaceae), Karen J. Vanderwolf, David Malloch, Donald F. Mcalpine
International Journal of Speleology
The introduction of the fungal pathogen Pseudogymnoascus destructans (Pd) to North America has stimulated research on the poorly known mycology of caves. It is possible that the introduction of Pd reduces the diversity of fungi associated with bats hibernating in caves. To test this hypothesis we examined the fungal assemblages associated with hibernating bats (Myotis spp.) pre- and post- white-nose syndrome (WNS) infection in eastern Canada using culture-dependent methods. We found the mean number of fungal taxa isolated from bats/hibernaculum was not significantly different between pre-infection (29.6 ± 6.1SD) and post-infection with WNS (32.4 ± 4.3). Although …
A World Review Of Fungi, Yeasts, And Slime Molds In Caves, Karen J. Vanderwolf, David Malloch, Donald F. Mcalpine, Graham J. Forbes
A World Review Of Fungi, Yeasts, And Slime Molds In Caves, Karen J. Vanderwolf, David Malloch, Donald F. Mcalpine, Graham J. Forbes
International Journal of Speleology
We provide a review of fungi, yeasts, and slime molds that have been found in natural solution caves and mines worldwide. Such habitats provide frequent roost sites for bats, and in eastern North America the environmental conditions that support white-nose syndrome, a lethal fungal disease currently devastating bat populations. A list of 1029 species of fungi, slime moulds, and yeasts in 518 genera have been documented from caves and mines worldwide in 225 articles. Ascomycota dominate the cave environment. Most research has been conducted in temperate climates, especially in Europe. A mean of 17.9±24.4SD fungal species are reported per study. …
