Identifying toxic impacts of metals potentially released during deep-sea mining...
Hauton, Chris; Brown, Alastair; Thatje, Sven; Mestre, Nélia; Bebianno, Maria; Martins, Inês; Bettencourt, Raul; Canals, Miquel; Sanchez-Vidal, AnnaIn January 2017, the International Seabed Authority released a discussion paper on the development of Environmental Regulations for deep-sea mining (DSM) within the Area Beyond National Jurisdiction (the “Area”). With the release of this paper, the prospect for commercial mining in the Area within the next decade has become very real. Moreover, within nations’ Exclusive Economic Zones, the exploitation of deep-...
Mammal carcasses attract a swarm of mussels in the deep Atlantic: insights into...
Génio, Luciana; Rodrigues, Clara F.; Guedes, Inês F.; Almeida, Hélio; Duperron, Sébastien; Hilário, AnaFive mammal carcasses were experimentally deployed at 1000 m depth in the Setubal Canyon (NE Atlantic) in March 2011 and the remaining bones were collected after 18 and 28 months. High numbers (1.92–6.27 individuals cm2) of small mussels were found among a diverse invertebrate assemblage colonizing surfaces, crevices and cavities in the trabecular matrix of bones. In this study we characterized the mussel popul...
Fickle or faithful: the roles of host and environmental context in determining ...
Laming, Sven R.; Szafranski, Kamil M.; Rodrigues, Clara F.; Gaudron, Sylvie M.; Cunha, Marina R.; Hilário, Ana; Le Bris, Nadine; Duperron, SébastienThe Mediterranean Sea and adjoining East Atlantic Ocean host a diverse array of small-sized mussels that predominantly live on sunken, decomposing organic remains. At least two of these, Idas modiolaeformis and Idas simpsoni, are known to engage in gill-associated symbioses; however, the composition, diversity and variability of these symbioses with changing habitat and location is poorly defined. The current s...
Adapted to change: the rapid development of symbiosis in newly settled, fast-ma...
Laming, Sven R.; Duperron, Sébastien; Gaudron, Sylvie M.; Hilário, Ana; Cunha, Marina R.Symbioses between microbiota and marine metazoa occur globally at chemosynthetic habitats facing imminent threat from anthropogenic disturbance, yet little is known concerning the role of symbiosis during early development in chemosymbiotic metazoans: a critical period in any benthic species' lifecycle. The emerging symbiosis of Idas (sensu lato) simpsoni mussels undergoing development is assessed over a post-l...
A complex picture of associations between two host mussels and symbiotic bacter...
Rodrigues, Clara F.; Cunha, Marina R.; Génio, Luciana; Duperron, SébastienAmong chemosymbiotic metazoans found at deep-sea hydrothermal vents, cold seeps and organic falls, members of the mussel clade Bathymodiolinae (Bivalvia: Mytilidae) have evolved interactions with a higher diversity of bacterial lineages than other bivalve groups. Here, we characterized the bacteria associated with "Bathymodiolus" mauritanicus and Idas-like specimens from three sites in the Northeast Atlantic (t...
The smaller vesicomyid bivalves in the genus Isorropodon (Bivalvia, Vesicomyida...
Rodrigues, Clara F.; Cunha, Marina R.; Olu, Karine; Duperron, SébastienSpecies of Isorropodon are vesicomyid bivalves for which little information is available regarding host phylogeny and bacterial symbioses. In this study we investigated the symbioses in three Isorropodon species from three cold seep areas: Isorropodon bigoti (Gulf of Guinea), Isorropodon megadesmus (Gulf of Cadiz) and Isorropodon perplexum (Eastern Mediterranean). Analysis of bacterial 16S ribosomal RNA gene se...
Diversity of symbioses between chemosynthetic bacteria and metazoans at the Gui...
Duperron, Sébastien; Rodrigues, Clara F.; Léger, Nelly; Szafranski, Kamil; Decker, Carole; Olu, Karine; Gaudron, Sylvie M.Fauna from deep-sea cold seeps worldwide is dominated by chemosymbiotic metazoans. Recently, investigation of new sites in the Gulf of Guinea yielded numerous new species for which symbiosis was strongly suspected. In this study, symbioses are characterized in five seep-specialist metazoans recently collected from the Guiness site located at ≈ 600 m depth. Four bivalve and one annelid species belonging to famil...
First documented record of a living solemyid bivalve in a pockmark of the Nile ...
Rodrigues, Clara F.; Duperron, Sébastien; Gaudron, Sylvie M.A living specimen of a solemyid bivalve was collected at bathyal depths near a pockmark in the Nile Deep-sea Fan (eastern Mediterranean) and is here presented. Both taxonomic and molecular results suggest a Solemya species but due to the small size of the animal and the lack of molecular data for other solemyid species the species cannot be determined. This is the first record of a living solemyid from deep-sea...
