    • Evidence for the Role of Endosymbionts in Regional-Scale Habitat Partitioning by Hydrothermal Vent Symbioses 

      Beinart, Roxanne Abra; Sanders, Jon Gregory; Faure, Baptiste; Sylva, Sean P.; Lee, Raymond W.; Becker, Erin L.; Gartman, Amy; Luther, George W.; Seewald, Jeffrey S.; Fisher, Charles R.; Girguis, Peter R. (Proceedings of the National Academy of Sciences, 2012)
      Deep-sea hydrothermal vents are populated by dense communities of animals that form symbiotic associations with chemolithoautotrophic bacteria. To date, our understanding of which factors govern the distribution of ...

    • The metabolic demands of endosymbiotic chemoautotrophic metabolism on host physiological capacities 

      Childress, J. J.; Girguis, Peter R. (The Company of Biologists, 2011)
      While chemoautotrophic endosymbioses of hydrothermal vents and other reducing environments have been well studied, little attention has been paid to the magnitude of the metabolic demands placed upon the host by symbiont ...

    • The Radiocarbon Signature of Microorganisms in the Mesopelagic Ocean 

      Hansman, Roberta L.; Griffin, Sheila; Watson, Jordan T.; Druffel, Ellen R. M.; Ingalls, Anitra E.; Pearson, Ann; Aluwihare, Lihini I. (National Academy of Sciences, 2009)
      Several lines of evidence indicate that microorganisms in the meso- and bathypelagic ocean are metabolically active and respiring carbon. In addition, growing evidence suggests that archaea are fixing inorganic carbon in ...
