March 1, 2008... ABSTRACT Three new northeastern Pacific species of the deep-sea limpet family Neolepetopsidae are described. One (Paralepetopsis tunnicliffae) is from the hydrothermal vent habitat, and two (Paralepetopsis clementensis and Neolepetopsis...

Taxonomic review of the hydrothermal vent shrimp genera Rimicaris Williams & Rona and Chorocaris Martin & Hessler (Crustacea: Decapoda: Caridea: Alvinocarididae).(Report)
March 1, 2008... ABSTRACT A taxonomic review of the two genera of the family Alvinocarididae (Decapoda: Caridea), Rimicaris Williams and Rona, 1986 and Chorocaris Martin and Hessler 1990, is presented based on study of type materials and/or supplemental...

DNA barcoding of Lepetodrilus limpets reveals cryptic species.(Report)
March 1, 2008... ABSTRACT Lepetodrilid limpets are common inhabitants of deep-sea hydrothermal vents worldwide, but the frequent occurrence of morphologically cryptic species makes their identification very difficult. To facilitate these identifications, we...

New record of "Bathymodiolus" mauritanicus Cosel 2002 from the Gulf of Cadiz (NE Atlantic) mud volcanoes.(Report)
March 1, 2008... ABSTRACT The "Bathymodiolus" childressi group is the most geographically diverse assemblage of deep-sea mussel species. In this paper we consider several possible hypotheses to explain the present biogeographic distribution of the "'B. "'...

Biology of the vent crab Bythograea thermydron: a brief review.(Report)
March 1, 2008... ABSTRACT This paper provides a review of relevant literature concerning the vent crab Bythograea thermydron. This body of work describes a crab species that shares fundamental biological characteristics with typical shallow-water brachyuran...

Interactions of deep-sea vent invertebrates with their environment: the case of Rimicaris exoculata.(Report)
March 1, 2008... ABSTRACT The vent shrimp Rimicaris exoculata thrives around many hydrothermal vent sites along the Mid-Atlantic Ridge (MAR), where it aggregates into dense swarms. In contrast to hydrothermal vent fields at the East Pacific Rise (EPR), where...

Biogeography, diversity, and evolution through vicariance of the hydrothermal vent aplacophoran genus Helicoradomenia (Aplacophora, Mollusca).(Report)
March 1, 2008... ABSTRACT Species of the neomenioid aplacophoran genus Helicoradomenia Scheltema & Kuzirian are found only in areas of hydrothermal vents, oceanic ridges, and back-arc basins and have been collected widely in the East Pacific, Southwest Pacific,...

Comparative ultrastructure of digestive diverticulae in Bathymodiolin mussels: discovery of an unknown spherical inclusion (six) in digestive cells of a seep mussel.(Report)
March 1, 2008... ABSTRACT Mussels in the genus Bathymodiolus host endosymbiotic bacteria in their gills, from which the mussel derives much of its nutrition. Bathymodiolin mussels also have functional digestive systems and, as in shallow-water mytilid mussels,...

Reproduction of gastropods from vents on the East Pacific rise and the Mid-Atlantic Ridge.(Report)
March 1, 2008... ABSTRACT The gametogenic biology is described for seven species of gastropod from hydrothermal vents in the East Pacific and from the Mid-Atlantic Ridge. Species of the limpet genus Lepetodrilus (Family Lepetodrilidae) had a maximum...

Extreme tolerance to anoxia in the Lucinoma aequizonata symbiosis.(Report)
March 1, 2008... ABSTRACT Our study describes the extraordinary capability of the endosymbiont-bearing bivalve Lucinoma aequizonata to tolerate environmental anoxia. The clam survives without oxygen for 262 days (50% mortality). The total quantity of glycogen...

Absence of cospeciation between deep-sea mytilids and their thiotrophic endosymbionts.(Report)
March 1, 2008... ABSTRACT Molecular phylogenetic analyses revealed no evidence for cospeciation between deep-sea bathymodiolin mussels (Bivalvia: Mytilidae) and their associated thiotrophic (sulfur-oxidizing) bacterial endosymbionts. Host and symbiont tree...

The morphology of bacterial symbioses in the gills of mussels of the genera Adipicola and Idas (Bivalvia: Mytilidae).(Report)
March 1, 2008... ABSTRACT Abundant bacteria have been found on the abfrontal regions of the gill filaments of three species of small mussels from a variety of habitats: Idas washingtoniana and Adipicola sp. from hydrothermal vents on the Juan de Fuca Ridge;...

Stable isotope variation among the mussel Bathymodiolus childressi and associated heterotrophic fauna at four cold-seep communities in the Gulf of Mexico.(Report)
March 1, 2008... ABSTRACT Efforts to determine the utilization of Gulf of Mexico (GOM) chemosynthetic production by benthic predators have relied on stable isotope differences between photosynthetic and chemosynthetic production. Whereas the photosynthetic...

Chemoautotrophic production incorporated by heterotrophs in Gulf of Mexico hydrocarbon seeps: an examination of mobile benthic predators and seep residents.(Report)
March 1, 2008... ABSTRACT The continental slope of the Gulf of Mexico supports dense aggregations of tubeworms and mussels that have symbiotic chemoautotrophic bacteria. Associated with these communities are numerous heterotrophic fauna and free-living...

Variation in sulfur speciation with shellfish presence at a Lau Basin diffuse flow vent site.(Report)
March 1, 2008... ABSTRACT Carbon fixation by sulfur-oxidizing chemosynthetic bacteria forms the base of the food chain in deep-sea (diffuse-flow) hydrothermal vent ecosystems. Temperature and the availability of oxygen and reduced sulfur are believed to be...

Hydrothermal vent mussel habitat chemistry, pre- and post-eruption at 9[degrees]50' north on the East Pacific Rise.(Report)
March 1, 2008... ABSTRACT Between October 2005 and March 2006, a seafloor volcanic eruption occurred at 9[degrees]50'N East Pacific Rise (EPR), establishing a "time zero" for characterizing newly-formed hydrothermal vent habitats and comparing them to...

Interrelationships between vent fluid chemistry, temperature, seismic activity, and biological community structure at a mussel-dominated, deep-sea hydrothermal vent along the East Pacific Rise.
March 1, 2008... ABSTRACT In April 1991, submarine volcanic eruptions initiated the formation of numerous hydrothermal vents between 9[degrees]45' and 9[degrees]52'N along the crest of the East Pacific Rise (EPR). Dramatic changes in biological community...
