title: Archaeal diversity and community development in deep-sea hydrothermal vents.
abstract: Over the past 35 years, researchers have explored deep-sea hydrothermal vent environments around the globe and studied a number of archaea, their unique metabolic and physiological properties, and their vast phylogenetic diversity. Although the pace of discovery of new archaeal taxa, phylotypes and phenotypes in deep-sea hydrothermal vents has slowed recently, bioinformatics and interdisciplinary geochemistry-microbiology approaches are providing new information on the diversity and community composition of archaea living in deep-sea vents. Recent investigations have revealed that archaea could have originated and dispersed from ancestral communities endemic to hydrothermal vents into other biomes on Earth, and the community structure and productivity of chemolithotrophic archaea are controlled primarily by variations in the geochemical composition of hydrothermal fluids.
