NCKRI: 2012-2013 Annual Report
The National Cave and Karst Research Institute (NCKRI) will be the world’s premier cave and karst research organization. NCKRI promotes and performs projects of national and international application, of the highest quality and integrity, through dedicated staff and partners. NCKRI is a non-profit 501(c)(3) corporation. It was created by the US Congress in 1998 in partnership with the National Park Service, State of New Mexico, and the City of Carlsbad. Federal and state funding for NCKRI is adminis- tered by the New Mexico Institute of Mining and Technolo- gy (aka New Mexico Tech or NMT). Funds not produced by agreements through NMT are accepted directly by NCKRI. NCKRI’s enabling legislation, the National Cave and Karst Research Institute Act of 1998, 16 U.S.C. §4310, iden- tifies NCKRI’s mission as to: 1) further the science of speleology; 2) centralize and standardize speleological information; 3) foster interdisciplinary cooperation in cave and karst research programs; 4) promote public education; 5) promote national and international cooperation in pro- tecting the environment for the benefit of cave and karst landforms; and 6) promote and develop environmentally sound and sus- tainable resource management practices.

L. Espinasa and N.H. Vuong ± A new species of cave adapted Nicoletiid (Zygentoma: Insecta) from Sistema Huautla, Oaxaca, Mexico: the tenth deepest cave in the world. Journal of Cave and Karst Studies, v. 70, no. 2, p. 73±77. A NEW SPECIES OF CAVE ADAPTED NICOLETIID (ZYGENTOMA: INSECTA) FROM SISTEMA HUAUTLA, OAXACA, MEXICO: THE TENTH DEEPEST CAVE IN THE WORLD LUIS ESPINASA AND NGUYET H. VUONG School of Science, Marist College, 3399 North Road, Poughkeepsie, NY 12601, [email protected] and [email protected] Abstract: Anelpistina specusprofundi, n. sp., is described and separated from other species of the subfamily Cubacubaninae (Nicoletiidae: Zygentoma: Insecta). The specimens were collected in SoÂtano de San AgustõÂn and in Nita Ka (Huautla system) in Oaxaca, MeÂxico. This cave system is currently the tenth deepest in the world. It is likely that A.specusprofundi is the sister species of A.asymmetrica from nearby caves in Sierra Negra, Puebla. The new species of nicoletiid described here may be the key link that allows for a deep underground food chain with specialized, troglobitic, and comparatively large predators suchas thetarantula spider Schizopelma grieta and the 70 mm long scorpion Alacran tartarus that inhabit the bottom of Huautla system. INTRODUCTION 760 m, but no human sized passage was found that joined it into the system. The last relevant exploration was in Among international cavers and speleologists, caves 1994, when an international team of 44 cavers and divers that surpass a depth of minus 1,000 m are considered as pushed its depth to 1,475 m. For a full description of the imposing as mountaineers deem mountains that surpass a caves of the Huautla Plateau, see the bulletins from these height of 8,000 m in the Himalayas. -

Banfield, Chair Understanding how microorganisms contribute to nutrient transformations within their community is critical to prediction of overall ecosystem function, and thus is a major goal of microbial ecology. Communities of relatively tractable complexity provide a unique opportunity to study the distribution of metabolic characteristics amongst microorganisms and how those characteristics subscribe diverse ecological functions to co-occurring, and often closely related, species. The microbial communities present in the low-pH, metal-rich environment of the acid mine drainage (AMD) system in Richmond Mine at Iron Mountain, CA constitute a model microbial community due to their relatively low diversity and extensive characterization over the preceding fifteen years. -
Geomicrobiology of Biovermiculations from the Frasassi Cave System, Italy
D.S. Jones, E.H. Lyon, and J.L. Macalady ± Geomicrobiology of biovermiculations from the Frasassi Cave System, Italy. Journal of Cave and Karst Studies, v. 70, no. 2, p. 78±93. GEOMICROBIOLOGY OF BIOVERMICULATIONS FROM THE FRASASSI CAVE SYSTEM, ITALY DANIEL S. JONES*,EZRA H. LYON 2, AND JENNIFER L. MACALADY 3 Department of Geosciences, Pennsylvania State University, University Park, PA 16802, USA, phone: tel: (814) 865-9340, [email protected] Abstract: Sulfidic cave wallshostabundant, rapidly-growing microbial communiti es that display a variety of morphologies previously described for vermiculations. Here we present molecular, microscopic, isotopic, and geochemical data describing the geomicrobiology of these biovermiculations from the Frasassi cave system, Italy. The biovermiculations are composed of densely packed prokaryotic and fungal cellsin a mineral-organic matrix containing 5 to 25% organic carbon. The carbon and nitrogen isotope compositions of the biovermiculations (d13C 5235 to 243%,andd15N 5 4to 227%, respectively) indicate that within sulfidic zones, the organic matter originates from chemolithotrophic bacterial primary productivity. Based on 16S rRNA gene cloning (n567), the biovermiculation community isextremely diverse,including 48 representative phylotypes (.98% identity) from at least 15 major bacterial lineages. Important lineagesinclude the Betaproteobacteria (19.5% of clones),Ga mmaproteobacteria (18%), Acidobacteria (10.5%), Nitrospirae (7.5%), and Planctomyces (7.5%). The most abundant phylotype, comprising over 10% of the 16S rRNA gene sequences, groupsin an unnamed clade within the Gammaproteobacteria. Based on phylogenetic analysis, we have identified potential sulfur- and nitrite-oxidizing bacteria, as well as both auto- and heterotrophic membersof the biovermiculation community. Additionally ,manyofthe clonesare representativesof deeply branching bacterial lineageswith n o cultivated representatives. -

BIOGEOCHEMICAL INTERACTIONS IN FLOODED UNDERGROUND MINES by Renée Schmidt A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Geoscience: Geochemistry Option Montana Tech 2017 ii Abstract This study presents a biogeochemical analysis of microbial communities in flooded underground mines in Butte, Montana, USA. Samples were collected from nine mineshafts representing three distinct geochemical zones. These zones consist of the East, West, and Outer Camp mines. The East Camp mines, bordering the Berkeley Pit Superfund site, have the highest concentrations of dissolved metals and the most acidic pH values. Dissolved metal concentrations in the West Camp are one to three orders of magnitude lower than in the East Camp and have nearly neutral pH values. The Outer Camp mines have similar metal concentrations to the West Camp but are neutral to alkaline in pH. Sulfide levels also differ between the zones. In the East Camp, sulfide levels were below detection limits, whereas the West and Outer Camp mines had sulfide -6 -4 18 concentrations ranging from 10 to 10 mol/L. -
Sulfur-Cycling and Microorganisms of the Frasassi Cave System, Italy
Sulfur-cycling and microorganisms of the Frasassi cave system, Italy By: Danielle Eastman Research Advisor: Dr. Gregory Druschel Senior Thesis 2007 University of Vermont Burlington VT, 05401 In Collaboration with: Dr. Jenn Macalady Dan Jones Lindsey Albertson Penn State University State College, PA 1 Abstract Sulfur utilizing bacteria in the Frasassi cave system of central Italy significantly contribute to the sulfur chemistry of the system. Microbial communities of sulfur- reducing and sulfur-oxidizing organisms in the sub-aqueous regions of the caves, as well as on the walls and ceilings, are catalysts for the majority of the oxidation-reduction reactions involved in sulfur cycling. Sulfide oxidation is the primary reaction of these chemical systems and fuels sulfuric acid speleogenesis. The overall rate at which sulfide is oxidized is dictated by biotic oxidation, which occurs at a much faster rate than abiotic oxidation. The sulfuric acid produced through biotic sulfide oxidation represents a biologically mediated process of speleogenesis. In addition to hosting a diverse selection of sulfur bacteria, including Beggiatoa spp, Thiovulum, and δ-proteobacteria, these sulfidic caves served as a natural laboratory for investigating the link between sulfur chemistry and biology. For this thesis a variety of chemotrophic microbial ecosystems, as well as phototrophic sulfur bacteria of the Frasassi caves, were studied. The comparison of these microbial communities provided information defining the pathways through which sulfur is oxidized, the rate at which oxidation occurs, and the chemical parameters that select for the dominant bacterial species of that community. Chemical niches, which selected for and are influenced by the bacteria, were investigated using electrochemical techniques. -
