“…Lucinids are usually found in shallow water, such as intertidal mud or seagrasses (4,53), in deeper water, e.g., Bathyaustriella thionipta (30), and in deep oceans at a 2,000-m depth, i.e., Lucinoma kazani (21,55). The chemoautotrophic endosymbionts involved in such relationships are always localized inside specialized cells called bacteriocytes, and they have been found in several genera of the Lucinidae family, such as Codakia (4,28), Loripes (39,43), Lucina, and Lucinoma (17).…”

The bivalve Codakia orbicularis, hosting sulfur-oxidizing gill endosymbionts, was starved (in artificial seawater filtered through a 0.22-m-pore-size membrane) for a long-term experiment (4 months). The effects of starvation were observed using transmission electron microscopy, fluorescence in situ hybridization and catalyzed reporter deposition (CARD-FISH), and flow cytometry to monitor the anatomical and physiological modifications in the gill organization of the host and in the symbiotic population housed in bacteriocytes. The abundance of the symbiotic population decreased through starvation, with a loss of one-third of the bacterial population each month, as shown by CARD-FISH. At the same time, flow cytometry revealed significant changes in the physiology of symbiotic cells, with a decrease in cell size and modifications to the nucleic acid content, while most of the symbionts maintained a high respiratory activity (measured using the 5-cyano-2,3-ditolyl tetrazolium chloride method). Progressively, the number of symbiont subpopulations was reduced, and the subsequent multigenomic state, characteristic of this symbiont in freshly collected clams, turned into one and five equivalent genome copies for the two remaining subpopulations after 3 months. Concomitant structural modifications appeared in the gill organization. Lysosymes became visible in the bacteriocytes, while large symbionts disappeared, and bacteriocytes were gradually replaced by granule cells throughout the entire lateral zone. Those data suggested that host survival under these starvation conditions was linked to symbiont digestion as the main nutritional source.

“…Although a limited number of samples were evaluated in that study, the number of molluscan species was high (23 species) as the samples were taken from the specific microhabitats of cold seeps, generally preferred by symbiont-bearing species (Salas & Woodside, 2002;Olu-Le Roy et al, 2004;Brissac et al, 2011).…”

The present study deals with the soft bottom molluscan species collected from the bathyal zone of the Sea of Marmara in 2013. Replicated samples were taken by a Box Core, sampling an area of 0.1 m2 at 31 stations at the two depth transects, 500 and 1000 m. A total of 1229 individuals belonging to 4 classes and 28 species were collected. Two species (Akritogyra conspicua and Liostomia hansgei) are new records for the marine molluscan fauna of Turkey and four species (Benthonella tenella, Odostomia silesui, Syrnola minuta and Crenilabium exile) are new records for the molluscan fauna of the Sea of Marmara. A relatively richer fauna was determined in 500 m (25 species) than in 1000 m (17 species). The most dominant species at 500 m and 1000 m depths were Crenilabium exile and Parthenina flexuosa, respectively. Number of species and number of individuals varied significantly only between depths while number of individuals changed significantly among basins (ANOVA test). A significant difference in species assemblages between the Tekirdağ and the Central Basins was detected (ANOSIM test). The multivariate analysis showed that the depth was the main factor influencing the molluscan assemblages in the area.

“…Lucinoma aff. kazani occurs at depths between 500 and 1709 m in the Anaximander Mountains between Rhodes and Cyprus, the Olimpi area south of Greece on the Mediterranean Ridge, and the Nile deep-sea fan (North Alex MV and pockmarks in the Central area); it was also recently reported from the Sea of Marmara (Bayon et al, 2009;Olu-LeRoy et al, 2004;Ritt et al, 2010;Salas and Woodside, 2002). The second species, Myrtea sp., possibly M. amorpha described in Olu et al (2004) and Ritt et al (2010), is closely related to M. spinifera based on 18S and 28S gene sequences, and is labeled Myrtea aff.…”

An overview of chemosynthetic symbioses in bivalves from the North Atlantic and Mediterranean Sea

et al. 2013

View full text Add to dashboard Cite

Deep-sea bivalves found at hydrothermal vents, cold seeps and organic falls are sustained by chemosynthetic bacteria that ensure part or all of their carbon nutrition. These symbioses are of prime importance for the functioning of the ecosystems. Similar symbioses occur in other bivalve species living in shallow and coastal reduced habitats worldwide. In recent years, several deep-sea species have been investigated from continental margins around Europe, West Africa, eastern Americas, the Gulf of Mexico, and from hydrothermal vents on the Mid-Atlantic Ridge. In parallel, numerous, more easily accessible shallow marine species have been studied. Herein we provide a summary of the current knowledge available on chemosymbiotic bivalves in the area ranging west-to-east from the Gulf of Mexico to the Sea of Marmara, and north-to-south from the Arctic to the Gulf of Guinea. Characteristics of symbioses in 53 species from the area are summarized for each of the five bivalve families documented to harbor chemosynthetic symbionts (Mytilidae, Vesicomyidae, Solemyidae, Thyasiridae and Lucinidae). Comparisons are made between the families, with special emphasis on ecology, life cycle, and connectivity. Chemosynthetic symbioses are a major adaptation to ecosystems and habitats exposed to reducing conditions. However, relatively little is known regarding their diversity and functioning, apart from a few "model species" on which effort has focused over the last 30 yr. In the context of increasing concern about biodiversity and ecosystems, and increasing anthropogenic pressure on oceans, we advocate a better assessment of the diversity of bivalve symbioses in order to evaluate the capacities of these remarkable ecological and evolutionary units to withstand environmental change
