Fungal diversity in deep-sea hydrothermal ecosystems.
Deep-sea hydrothermal ecosystems are considered oases of life in oceans. Since the discovery of these ecosystems in the late 1970s, many endemic species of Bacteria, Archaea, and other organisms, such as annelids and crabs, have been described. Considerable knowledge has been acquired about the diversity of (micro)organisms in these ecosystems, but the diversity of fungi has not been studied to...
متن کاملThe Biological Deep Sea Hydrothermal Vent as a Model to Study Carbon Dioxide Capturing Enzymes
Deep sea hydrothermal vents are located along the mid-ocean ridge system, near volcanically active areas, where tectonic plates are moving away from each other. Sea water penetrates the fissures of the volcanic bed and is heated by magma. This heated sea water rises to the surface dissolving large amounts of minerals which provide a source of energy and nutrients to chemoautotrophic organisms. ...
متن کاملTesting biological control of colonization by vestimentiferan tubeworms at deep-sea hydrothermal vents
Three species of vestimentiferans are found at hydrothermal vents on the East Pacific Rise (EPR). Tevnia jerichonana is an early colonist and Riftia pachyptila has the greatest biomass in established vent assemblages, but the role of Oasisia alvinae, a small species that occurs sporadically, is unknown. Anecdotal evidence suggests that O. alvinae may be abundant in the microhabitat underneath m...
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 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...
