Microorganisms as food resources at deep-sea hydrothermal vents
We used stable isotopes of carbon and nitrogen to examine the diversity of microbial populations consumed as foods at deep-sea hydrothermal vents. Invertebrate consumers at Gorda and Juan de Fuca Ridge vent sites had variable carbon isotope compositions, implying the use of more than one microbial food resource. 6’C values for consumer invertebrates at Gorda ranged between 13.2% (polynoid polyc...
متن کاملCommunity structure of mussel beds at deep-sea hydrothermal vents
Definition of biogeographic provinces, patterns of species distributions on local and regional scales, species richness, and relative abundances are all basic ecological measures, yet they are largely unknown for deep-sea hydrothermal vent ecosystems. Without an appreciation of biogeographic and biodiversity patterns, it is difficult to understand the evolutionary and ecological processes that ...
متن کاملMarine culturable yeasts in deep-sea hydrothermal vents:
26 The diversity of culturable yeasts at deep-sea hydrothermal sites has been investigated and 27 raises emerging hints regarding interactions with endemic fauna. Samples were collected 28 during diverse oceanographic cruises at Mid-Atlantic Ridge, South Pacific Basins and East 29 Pacific Rise. A culture collection of thirty-two isolates mostly associated with animals was 30 performed. The phyl...
متن کاملAntarctic Marine Biodiversity and Deep-Sea Hydrothermal Vents
The diversity of many marine benthic groups is unlike that of most other taxa. Rather than declining from the tropics to the poles, much of the benthos shows high diversity in the Southern Ocean. Moreover, many species are unique to the Antarctic region. Recent work has shown that this is also true of the communities of Antarctic deep-sea hydrothermal vents. Vent ecosystems have been documented...
متن کاملAbundance of reverse tricarboxylic acid cycle genes in free-living microorganisms at deep-sea hydrothermal vents.
Since the discovery of hydrothermal vents more than 25 years ago, the Calvin-Bassham-Benson (Calvin) cycle has been considered the principal carbon fixation pathway in this microbe-based ecosystem. However, on the basis of recent molecular data of cultured free-living and noncultured episymbiotic members of the epsilon subdivision of Proteobacteria and earlier carbon isotope data of primary con...
