“…Clear patterns of macrofaunal species succession and evolving hydrothermal conditions have been observed on sulfide edifices, and around newly emerged vents following seafloor volcanic eruptions, on the Juan de Fuca Ridge (Marcus et al, 2009) as well as on the East Pacific Rise (Mullineaux et al, 2003;Shank et al, 1998). Chemical, substratum, and community relationships have also been documented in the Lau Basin (Podowski et al, 2009;Sen et al, 2013). Thermal tolerance differences between species, observed in pressurized aquarium studies (e.g.…”

“…The resulting faunal and temperature time-series will enable detailed study of faunal responses to temperature change events and longer term trends. (Sen et al, 2013). Nevertheless, temperature variability at sublethal levels may be an important indicator of associated chemical changes and resultant potential influences on animal behavior, physiological costs, and growth of microbial food sources.…”

(2015) Molecular taxonomy and naming of five cryptic species of Alviniconcha snails (Gastropoda: Abyssochrysoidea) from hydrothermal vents, Systematics and Biodiversity, 13:3, 278-295, DOI: 10.1080/14772000.2014 Large symbiont-hosting snails of the genus Alviniconcha (Gastropoda: Abyssochrysidae) are among the dominant inhabitants of hydrothermal vents in the Western Pacific and Indian oceans. The genus was originally described as monotypic, but unique DNA sequences for mitochondrial genes revealed six distinct evolutionary lineages that we could not distinguish based on external morphology. Subsumed under the name Alviniconcha hessleri Okutani & Ohta, the distinct allopatric and sympatric lineages have been assigned placeholder epithets that complicate scientific communications. Based on the present multi-gene sequence data, we hereby describe five Alviniconcha species (in the order of their discovery) À A. kojimai sp. nov., A. boucheti sp. nov., A. marisindica sp. nov., A. strummeri sp. nov. and A. adamantis sp. nov. Thus, we restrict application of the name A. hessleri to specimens that are genetically similar (95% for COI) to those found at localities in the Mariana Trough. Single distinct Alviniconcha species inhabit vent fields along the Central Indian Ridge, the Mariana volcanic arc, and the Mariana back-arc basin, whereas vents in the Manus, Fiji and Lau back-arc basins may host two or three additional species. Formal recognition of these species facilitates future attempts to assess their physiological differences and symbiont associations. Furthermore, their reported distributions have significant biogeographic implications, affecting estimates of the diversity within and overlap among Indo-Pacific vent localities.http://zoobank.org/urn:lsid:zoobank.org:pub:1E4B2E71-9F1D-479E-9A9A-22A9E303AAE5

“…The sulfide concentrations measured on GHP5 were at the milimolar level, which is likely not 5 limiting with respect to supporting chemosynthesis based fauna of this size. Though the exact sulfide needs of frenulates and O. haakonmosbiensis have not been quantified, significantly larger chemoautotrophic symbioses are known to be found in environments with lower in situ concentrations of dissolved sulfide (Decker et al, 2017;Podowski et al, 2010;Sarrazin et al, 1999;Sen et al, 2013;Urcuyo et al, 2003). Therefore, the sediment at GHP5 contains more than enough sulfide to theoretically support O. haakonmosbiensis, and yet, they are absent from this pingo.…”

Cold seep communities around gas hydrate mounds (pingos) in the Western Barents Sea (76°N, 16°E, ~400 m depth) were investigated with high resolution, geographically referenced images acquired with an ROV and towed camera. Four pingos associated with seabed methane release hosted diverse biological communities of mainly non-seep (background) species including commercially important fish and crustaceans, as well as a species new to this area (the snow crab Chionoecetes 15 opilio). We attribute the presence of most benthic community members to habitat heterogeneity and the occurrence of hard substrates (methane derived authigenic carbonates), particularly the most abundant phyla (Cnidaria and Porifera), though food availability and exposure to a diverse microbial community is also important for certain taxa. Only one chemosynthesis based species was confirmed, the siboglinid frenulate polychaete, Oligobrachia haakonmosbiensis. Overall, the pingo communities formed two distinct clusters, distinguished by the presence or absence of frenulates. Methane gas advection through sediments 20 was absent below the single pingo that lacked frenulates, while seismic profiles indicated gas saturated sediment below the other frenulate colonized pingos. The absence of frenulates could not be explained by sediment sulfide concentrations, despite these worms likely containing sulfide oxidizing symbionts. We propose that high levels of seafloor methane seepage linked to sub-surface gas reservoirs support an abundant and active sediment methanotrophic community that maintains high sulfide fluxes and serves as a carbon source for frenulate worms. The pingo currently lacking a sub-surface gas source and lower 25 methane concentrations has lower sulfide flux rates and limited amounts of carbon insufficient to support frenulates. Two previously undocumented behaviors were visible through the images: grazing activity of snow crabs on bacterial mats, and seafloor crawling of Nothria conchylega onuphid polychaetes.Biogeosciences Discuss., https://doi
