Hot Spring Ecosystems
|
| Hot springs support a stunning
diversity of thermofluidic microorganism, many of which rely on
geochemical sources of energy. We are studying the links between hot
spring chemistry and biology at Yellowstone National Park Field and
laboratory analytical data, together with thermodynamic calculations,
allow us to quantify the energy supply from hundreds of reactions used by
microbes. Ranking the energy supply leads to testable hypotheses about the
community structure of microorganisms. Our goal is to develop
predictable methods for microbiology derived from geochemical variables
