PMID: 38366040
Deep-sea hydrothermal vent geochemistry shapes the foundation of the microbial food web by fueling chemolithoautotrophic microbial activity. Microbial eukaryotes (or protists) play a critical role in hydrothermal vent food webs...

PMID: 38346185
Most of the geologic CO entering Earth's atmosphere and oceans is emitted along plate margins. While C-cycling at mid-ocean ridges and subduction zones has been studied for decades, little attention...

. 2021 Nov;
88(2):e0208321.
PMID: 34788061
Molecular surveys of low temperature deep-sea hydrothermal vent fluids have shown that (previously ) often dominate the microbial community and that three genera, , , and , frequently coexist. In...

Proc Natl Acad Sci U S A
. 2021 Jul;
118(29).
PMID: 34266956
Microbial eukaryotes (or protists) in marine ecosystems are a link between primary producers and all higher trophic levels, and the rate at which heterotrophic protistan grazers consume microbial prey is...

Proc Natl Acad Sci U S A
. 2020 Aug;
117(34):20453-20461.
PMID: 32817473
Subseafloor mixing of high-temperature hot-spring fluids with cold seawater creates intermediate-temperature diffuse fluids that are replete with potential chemical energy. This energy can be harnessed by a chemosynthetic biosphere that...

PMID: 32605604
Background: Deep-sea hydrothermal vents are highly productive biodiversity hotspots in the deep ocean supported by chemosynthetic microorganisms. Prominent features of these systems are sulfide chimneys emanating high-temperature hydrothermal fluids. While...
