Microbiology in Yellowstone National Park.
Yellowstone National Park plays host to numerous microbiological research projects — officially 23, according to the 1996 Investigators' Annual Reports. However, once categories such as aquatic ecology, the study of brucellosis and other wildlife diseases, environmental education, geochemistry and geothermal systems, and vegetation are included, the total came to at least 35 in 1996. Research p...
متن کاملAquificales in Yellowstone National Park
Aquificales are metabolically versatile chemolithoautotrophic thermophilic bacteria. This group is widespread in both deep-sea and terrestrial hydrothermal systems. In Yellowstone National Park, they were first described in early descriptions of the biology of the park, and later captured the attention of many microbiologists including Brock, Stahl, Pace, and others. There are four genera curre...
متن کاملLipid biomarkers and carbon-isotopes of modern travertine deposits (Yellowstone National Park, USA): Implications for biogeochemical dynamics in hot-spring systems
Lipid biomarkers and C fractionation patterns were used to understand the dynamics of carbon cycling during microbial metabolisms in different environments of travertine precipitation (called facies) at Spring AT-1 on Angel Terrace in the Mammoth Hot Springs complex of Yellowstone National Park, USA. Microbial mats that encrust travertine deposits were collected for analyses of lipid biomarkers...
متن کاملAmphibian decline in Yellowstone National Park.
We conduct long-term amphibian monitoring in Yellowstone National Park (YNP) (1) and read McMenamin et al.’s article (2) with interest. This study documents decline in the extent of seasonal wetlands in the Lamar Valley of YNP during extended drought, but the conclusion, widely reported in the media, of ‘‘severe declines in 4 once-common amphibian species,’’ is unsupported. This study wrongly d...
متن کاملDepositional facies and aqueous-solid geochemistry of travertine-depositing hot springs (Angel Terrace, Mammoth Hot Springs, Yellowstone National Park, U.S.A.).
Petrographic and geochemical analyses of travertine-depositing hot springs at Angel Terrace, Mammoth Hot Springs, Yellowstone National Park, have been used to define five depositional facies along the spring drainage system. Spring waters are expelled in the vent facies at 71 to 73 degrees C and precipitate mounded travertine composed of aragonite needle botryoids. The apron and channel facies ...
