Thermal Tolerances of an Endemic Hot Spring Snail Physella wrighti Te and Clarke (Mollusca: Physidae)
… Endangered freshwater snail endemic to the Liard Hot Springs in northern British Columbia. It inhabits water temperatures from 23.5oC to 36oC and is active year-round. Despite its conservation status, little else is known about this species. To advance our understanding of P. wrighti in its …

MICROBIAL COMMUNITY ASSEMBLY AND DIVERSIFICATION OF THE GENUS CHLOROFLEXUS ALONG AN ALKALINE HOT SPRING GRADIENT
… of bacterial communities present in alkaline hot springs in Yellowstone National Park. I focus specifically on White Creek and Rabbit Creek in the Lower Geyser Basin. I show that, overall, the bacterial communities of both creeks are non-randomly assembled. However, at finer taxonomic scales, …

Biochemical characterisation of an alpha-amylase with pullulan hydrolase type III characteristics derived from a hot spring metagenomics library
… to identify novel glycosyl hydrolase enzymes in shotgun metagenomic sequence data from the Mphizi hot spring in Malawi. An identified ORF, named Pull3.1, displayed low sequence identity to a characterised α-amylase (62.71%) and 61.66% to a characterised pullulan hydrolase type III, and was, …

Microbial phylogenetic diversity preserved in facies-specific modern, recent, Holocene and Pleistocene hot-spring travertine deposits of Yellowstone and Turkey
… within modern-to-ancient terrestrial hot-spring calcium carbonate (CaCO3) limestone deposits called travertine. Microbial 16S rRNA gene sequences preserved within Modern travertine deposited within the Proximal Slope Facies (PSF) at Mammoth Hot Springs (MHS), Yellowstone National Park, …

Sedimentology and stratigraphy of the early Pennsylvanian Upper Jackfork interval in the Caddo Valley quadrangle, Clark and Hot Spring counties, Arkansas
Includes bibliographical references (pages 196-207).

Structural Controls of the MacFarlane Geothermal System, Humboldt County, Nevada: New Insights Based on Detailed Geologic Mapping, Shallow Temperature Surveys, and Magnetic Data
… of the MacFarlane geothermal system. MacFarlane hot springs and the travertine fissure ridges lie within a relay ramp. The relay ramp is formed between two overlapping, north-northeast-striking, west-dipping Holocene normal faults exposed in Lake Lahontan sediments. Other mapped faults near the …

Characteristics of cone-forming cyanobacteria and implications for the origin of conical stromatolites
… rock, may contain the earliest records of phototaxis, photosynthesis, and oxygenation of the environment. The reconstruction of the co-evolution of biology and the environment using stromatolites depends on the ability to recognize macroscopic shapes that arise uniquely as a consequence of …

Evolutionary and ecological consequences of chronic infection in Sulfolobus islandicus
… diverse natural populations living in the acidic hot spring system and supports the emergent mutualism that exists in this virus-host interaction.

Investigations on the taxonomy and the genetics of caldoactive bacteria
… thermophilic bacteria isolated from New Zealand hot springs. The New Zealand isolates were compared with a number of appropriate reference strains obtained from culture collections or as gifts from other laboratories. Three groups of bacteria were analysed. The Thermus-like group was found to …

Complex Fluid Dynamics: From Laminar to Geophysical Flows
… terrace architecture found at carbonate hot springs. Our numerical model predicts dynamical phenomena which are seen at real hot springs. It also produces patterns which have the same static statistical properties as those seen at real hot springs, and indicates that hot spring terraces …

Detailed Analysis of Geothermal Potential in Crescent Valley, North-Central Nevada
… geothermal system, including Hand-Me-Down Creek, Hot Springs Point, and three other unnamed areas. The Hand-Me-Down Creek hybrid structural setting along the Crescent Valley fault is the only documented relatively high temperature geothermal system identified in the basin. It contains an active …

Sequestration of metal and metalloid ions by thermophilic bacteria
… was to characterize microbial populations in the hot spring Champagne Pool, located in Waiotapu, New Zealand. The thermal spring is approximately 65 m in diameter and discharges water at 75eg; C and pH 5.5, which is oversaturated with arsenic and antimony compounds that precipitate and form orange …

The characterisation of three hyperthermophilic archaea from New Zealand hot springs
… of hyperthermophilic archaea from New Zealand hot springs. Three organisms were chosen for investigation. The coccoid isolate Wai21.S1 is a novel strain of the genus Thermococcus that was isolated from a hot spring at Waimangu Volcanic Valley. It is only the second described fresh-water isolate …

Molecular pathways of silica nanoparticle formation and biosilicification
… The diversity of microbial communities in hot spring environments appeared to be directly controlled by the physico-chernical conditions of the geothermal waters (i. e., T,pH, salinity and sinter growth rate) and the most dominant phylotypes were related to Aquificae, Deinococci and …

Uranium-series geochronology and stable isotope analysis of travertine from Soda Dam, New Mexico : a Quaternary record of episodic spring discharge and rivern incision in the Jemez Mountains hydrothermal system
… at least the last 500 ka. Travertine-depositing springs occur in San Diego Canyon, the only surface drainage outlet for the Valles Caldera, along the intersection of the Jemez fault zone (JFZ) and the Jemez River. This travertine-depositing hot spring system is part of the Valles Caldera …
