Growth of bivalves at deep-sea hydrothermal vents along the galapagos rift.
نویسندگان
چکیده
Direct measurements of shell growth of an unclassified mussel from active hydrothermal vents along the Galápagos Rift reveal growth rates of approxmately 1 centimeter per year for mature specimens. The largest mussel collected (with shell length of 18.4 centimeters) was estimated to be 19 +/- 7 years old at the time of sampling. Recorded growth rates are among the highest documented for deep-sea species.

| Chemosynthetic symbioses between bacteria and marine invertebrates were discovered 30 years ago at hydrothermal vents on the Galapagos Rift. Remarkably, it took the discovery of these symbioses in the deep sea for scientists to realize that chemosynthetic symbioses occur worldwide in a wide range of habitats, including cold seeps, whale and wood falls, shallow-water coastal sediments and cont...
متن کاملDeep-sea hydrothermal vents as natural egg-case incubators at the Galapagos Rift
The discovery of deep-sea hydrothermal vents in 1977 challenged our views of ecosystem functioning and yet, the research conducted at these extreme and logistically challenging environments still continues to reveal unique biological processes. Here, we report for the first time, a unique behavior where the deep-sea skate, Bathyraja spinosissima, appears to be actively using the elevated temper...

•Eight species of scaled polychaetes are reported from hydrothermal vents of the Guaymas Basin in the Gulf of California; Neoleanira racemosa in the Sigalionidae and seven species of Polynoidae, including two new species, Bathykurila guaymasensis, in Macellicephalinae, and Macellicephaloides alvini, in Macellicephaloidinae. The latter genus and subfamily are reviewed, and a Key to the seven spe...
متن کاملAdvances in Taxonomy, Ecology, and Biogeography of Dirivultidae (Copepoda) Associated with Chemosynthetic Environments in the Deep Sea
BACKGROUND Copepoda is one of the most prominent higher taxa with almost 80 described species at deep-sea hydrothermal vents. The unique copepod family Dirivultidae with currently 50 described species is the most species rich invertebrate family at hydrothermal vents. METHODOLOGY/PRINCIPAL FINDINGS We reviewed the literature of Dirivultidae and provide a complete key to species, and map geogr...

Species diversity, phylogenetic affiliations, and environmental occurrence patterns of thiosulfate-oxidizing marine bacteria were investigated by using new isolates from serially diluted continental slope and deep-sea abyssal plain sediments collected off the coast of New England and strains cultured previously from Galapagos hydrothermal vent samples. The most frequently obtained new isolates,...
