Using data on ocean circulation with a Lagrangian larval transport model, we modeled the potential dispersal distances for seven species of bathyal invertebrates whose durations life have been estimated from laboratory rearing, MOCNESS plankton sampling, spawning times, and recruitment. Species associated methane seeps in Gulf Mexico and/or Barbados included bivalve "Bathymodiolus" childressi, gastropod Bathynerita naticoidea, siboglinid polychaete tube worm Lamellibrachia luymesi, asteroid...
We describe culturing techniques and development for the cold-seep mussel "Bathymodiolus" childressi, only deep-sea bivalve which has been detailed. Spawning was induced in mature mussels by injection of 2 mmol l(-1) serotonin into anterior adductor muscle. The mean egg diameter is 69.15 +/- 2.36 microm (+/-S.D.; n = 50) eggs are negatively buoyant. Cleavages spiral at 7-8 degrees C occur a rate one per 3-9 h through hatching, with free-swimming blastulae hatching 40 shells beginning to...
Many species endemic to deep-sea methane seeps have broad geographical distributions, suggesting that they produce larvae with at least episodic long-distance dispersal. Cold-seep communities on both sides of the Atlantic share or complexes, yet larval dispersal across is expected take prohibitively long adult depths. Here, we provide direct evidence long-lived two cold-seep molluscs migrate hundreds metres above ocean floor, allowing them advantage faster surface currents may facilitate We...
Background The barnacle Balanus amphitrite is a globally distributed biofouler and model species in intertidal ecology larval settlement studies. However, lack of genomic information has hindered the comprehensive elucidation molecular mechanisms coordinating its settlement. pyrosequencing-based transcriptomic approach thought to be useful identify key changes during Methodology Principal Findings Using 454 pyrosequencing, we collected totally 630,845 reads including 215,308 from stages...

Abstract Most volcanic eruptions on Earth take place below the ocean surface and remain largely unobserved. Reconstruction of past submerged has thus primarily been based study seafloor deposits. Rarely before 15 January 2022 eruption Hunga volcano (Kingdom Tonga) have we able to categorically link deep‐sea deposits a specific source. This was largest in modern satellite era, producing 58‐km‐tall plume, 20‐m high tsunami, pressure wave that propagated around world. The induced fastest...
The barnacle Balanus amphitrite (=Amphibalanus amphitrite) is a major marine biofouling invertebrate worldwide. It has complex life cycle during which the larva (called nauplius) molts six times before transforming into cyprid stage. stage in B. critical for larval decision to attach and metamorphose. In this study, proteome phosphoproteome alterations development/aging upon treatment with antifouling agent butenolide were examined two-dimensional electrophoresis (2-DE) multiplexed...
Most invertebrates in the ocean begin their lives with planktonic larval phases that are critical for dispersal and distribution of these species. Larvae particularly vulnerable to environmental change, so understanding interactive effects stressors on life is essential predicting population persistence vulnerability Here, we use a novel experimental approach rear larvae under interacting gradients temperature, salinity, acidification, then model growth rate duration Olympia oyster predict...
Abstract Mass mortality of marine animals due to volcanic ash deposition is present in the fossil record but has rarely been documented real time. Here, using remotely-operated vehicle video footage and analysis collected at seafloor, we describe devastating effect record-breaking 2022 Hunga submarine eruption on endangered vulnerable snail mussel species that previously thrived nearby deep-sea hydrothermal vents. In contrast grazing, scavenging, filter-feeding, predatory vent taxa, observed...
Larval settlement and metamorphosis of a common biofouling polychaete worm, Hydroides elegans, involve remarkable structural physiological changes during this pelagic to sessile habitat shift. The endogenous protein molecules post-translational modifications that drive larval transition process are not only interest ecologists but also the antifouling paint industry, which aims control species on man-made structures (e.g., ship hulls). On basis our recent proteomic studies, we hypothesize...
The marine invertebrate Bugula neritina has a biphasic life cycle that consists of swimming larval stage and sessile juvenile adult stage. attachment larvae to the substratum their subsequent metamorphosis have crucial ecological consequences. Despite many studies on this species, little is known about molecular mechanism these processes. Here, we report comparative study metamorphosing individuals at 4 24 h postattachment using label-free quantitative proteomics. We identified more than...
Metamorphosis in the bryozoan Bugula neritina (Linne) includes an initial phase of rapid morphological rearrangement followed by a gradual morphogenesis. We hypothesized that first may be independent de novo synthesis proteins and, instead, involves post-translational modifications existing proteins, providing simple mechanism to quickly initiate metamorphosis. To test our hypothesis, we challenged B. larvae with transcription and translation inhibitors. Furthermore, employed 2D gel...
Abstract Bathynerita naticoidea (Gastropoda: Neritidae) and Methanoaricia dendrobranchiata (Polychaeta: Orbiniidae) are two of the most abundant invertebrates associated with cold‐seep mussel beds in Gulf Mexico. At methane seep known as Brine Pool NR‐1 (27 °43.415 N, 91 °16.756 W; 650 m depth), which is surrounded by a broad band mussels ( Bathymodiolus childressi ), these species have distinctly different patterns abundance, gastropod being found mostly at outer edge bed (average density...

Abstract Dispersal, retention, and population connectivity are impacted by current regime the behaviors that drive larval distribution, so understanding both is key to informing restoration of native species like Olympia oyster ( Ostrea lurida ) across its range in western North America. This study explores relationships between several factors (temperature, [chl a], size, tidal stage, estimated speed) vertical distributions Fidalgo Bay (48.4828, − 122.5811), a shallow, tidally flushed bay...
