Estimation of History of Hydrothermal Activities Based on Evolutionary Ecology of Chemosynthesis-based Communities
This paper introduces communities in hydrothermal vent fields and describes the principals of methodologies for age estimation, which are now planning, and the expected results. Expand
Rate and process of tube production by the deep-sea hydrothermal vent tubeworm Riftia pachyptila
The presence of clumps of freshly secreted tube material at the base of the exoskeleton as well as the new observation of bifid tubes allow us to propose a model of tube growth at both ends, which shows a variation of the gross morphology of the plume and the trunk of R. pachyptlla during growth and indicates that vestlmentum length and tube diamctrr could be useful indices of lndlv~dual and tube sizes.

We examine evidence for links between seafloor spreading rate and properties of vent habitat most likely to influence species diversity and other ecosystem properties. Abundance of vent habitat alongExpand
Novel insights on obligate symbiont lifestyle and adaptation to chemosynthetic environment as revealed by the giant tubeworm genome
It is posited that the innate immune system plays a more prominent role into the establishment of the symbiosis during the infection in the larval stage, rather than maintaining the symbiostasis in the trophosome. Expand
A primer for use of genetic tools in selecting and testing the suitability of set-aside sites protected from deep-sea seafloor massive sulfide mining activities
A checklist for environmental regulators forms a guide to aid decision making on the suitability of set-aside design and assessment using genetic tools. Expand
Settlement, growth and reproduction in the deep-sea wood-boring bivalve mollusc Xylophaga depalmai
Experimental panels of spruce and oak deployed at 3 and 6 mo intervals over a period of several years at ca. 500 m depth in the NE Tongue of the Ocean, Bahamas, were rapidly colonised by theExpand
1 Symbiosis of Thioautotrophic Bacteria with Riftia pachyptila
The symbiosis between the giant vestimentiferan tubeworm Riftia pachyptila and an intracellular sulfur-oxidizing bacterium still fascinates researchers over 20 years after its discovery. ThisExpand
Glycogen storage in the Riftia pachyptila trophosome: contribution of host and symbionts
Glycogen storage in host tissue and symbiotic bacteria in the anterior trophosome of theimentiferan tubeworm Riftia pachyptila Jones, 1981, was investigated using transmission elec-tron microscope and stereological methods to show that host and symbionts contribute equally to the total glycogen content of the trophOSome.

Preliminary data on carbon production of deep-sea vent tubeworms
Vestimentiferan tube growth alone would indicate that this vent site is a remarkable benthic hotspot for carbon production, and it seems that these rates differ depending on the in situ origin of the animals, thus suggesting that in the future this type of experiment may provide quantitative information concerning the vitality of different vent sites.

Gene flow and genetic diversity in naturally fragmented metapopulations of deep-sea hydrothermal vent animals.
The ephemeral nature of deep-sea hydrothermal vents is expected to favor species with good colonization abilities, high dispersal rates, and rapid individual growth rates, while bivalve species, which are restricted to a few of the known vent sites, appear at a later successional stage and have lower levels of variability.

In Situ Spawning of Hydrothermal Vent Tubeworms (Riftia pachyptila).
A dive series made by the submersible Alvin in the vicinity of 9{deg}50'N on the East Pacific Rise, I observed spawning tubeworms while I was sampling associated fauna and a brief account of the spawning activity is presented. Expand
Volcanic eruption of the mid-ocean ridge along the East Pacific Rise crest at 9°45-52'N: direct submersible observations of seafloor phenomena associated with an eruption event in April, 1991
In April, 1991, we witnessed from the submersible Alvin a suite of previously undocumented seafloor phenomena accompanying an in-progress eruption of the mid-ocean ridge on the East Pacific RiseExpand
A comparison of bivalve (Calyptogena magnifica) growth at two deep-sea hydrothermal vents in the eastern Pacific
These data provide additional evidence that biological processes at submarine hydrothermal vents along the mid-oceanic ridge system proceed at rates that are extremely rapid for a deep-sea environment and are comparable with those from some shallow water temperate environments. Expand
Hydrothermal Vent Animals: Distribution and Biology
There are similarities in the animal distributions at vent communities from 20�S to 46�N on the Mid-Ocean Ridge in the Pacific Ocean and at cold sulfide seeps in the Gulf of Mexico. Expand
