Bacterial diversity in hydrothermal sediment and epsilonproteobacterial dominance in experimental microcolonizers at the Mid-Atlantic Ridge.
TLDR
A molecular survey based on 16S rRNA genes of the bacterial diversity found in two deep-sea vent niches at the Mid-Atlantic Ridge shows that microcolonizers were almost exclusively colonized by epsilonproteobacteria, although these exhibited considerable morphological and phylogenetic in-group diversity.
Delayed Selfing as an Optimal Mating Strategy in Preferentially Outcrossing Species: Theoretical Analysis of the Optimal Age at First Reproduction in Relation to Mate Availability
TLDR
This model predicts the evolution of an optimal waiting time depending on the efficiency of resource reallocation to late fecundity, on the inbreeding depression, and on the instantaneous probability of encountering a partner versus dying.
A dual symbiosis shared by two mussel species, Bathymodiolus azoricus and Bathymodiolus puteoserpentis (Bivalvia: Mytilidae), from hydrothermal vents along the northern Mid-Atlantic Ridge.
TLDR
Analysis of mussels collected from four MAR vent sites showed that the two mussel species share highly similar to identical symbiont phylotypes, indicating that vent chemistry may influence the relative abundance of thiotrophs and methanotrophs in these dual symbioses.
Dual Symbiosis in a Bathymodiolus sp. Mussel from a Methane Seep on the Gabon Continental Margin (Southeast Atlantic): 16S rRNA Phylogeny and Distribution of the Symbionts in Gills
TLDR
The first thiotrophic sequence from a seep mussel is described and it is shown that it is most closely related (99% sequence identity) to an environmental clone sequence obtained from a hydrothermal plume near Japan.
Diversity, relative abundance and metabolic potential of bacterial endosymbionts in three Bathymodiolus mussel species from cold seeps in the Gulf of Mexico.
TLDR
A gene characteristic of methane-oxidzing bacteria, pmoA, was identified in all three mussel species confirming the methanotrophic potential of their symbionts, and stable isotope analyses of lipids and whole tissue confirmed the importance of meethanotrophy in the carbon nutrition of all of the mussels.
Unexpected co-occurrence of six bacterial symbionts in the gills of the cold seep mussel Idas sp. (Bivalvia: Mytilidae).
TLDR
The report of a multiple symbiosis involving six distinct bacterial 16S rRNA phylotypes in a small Idas mussel found on carbonate crusts in a cold seep area located north to the Nile deep-sea fan shows that symbiont diversity has probably been underestimated, and questions whether the common ancestor of bathymodioline mussels was associated with multiple bacteria.
Microbial diversity associated with the hydrothermal shrimp Rimicaris exoculata gut and occurrence of a resident microbial community.
TLDR
The hypothesis of a symbiotic relationship between R. exoculata and its gut epibionts is reinforced, as filamentous bacteria, inserted between microvilli of gut epithelial cells, remained after starvation periods in empty guts, suggesting the occurrence of a resident microbial community.
Colonization of organic substrates deployed in deep-sea reducing habitats by symbiotic species and associated fauna.
TLDR
Test whether typical vent/seep organisms harbouring symbionts or not, would be able to settle on organic substrates deployed in the vicinity of chemosynthetic ecosystems attracted both fauna relying on chemosynthesis-derived carbon as well as fauna relied on heterotrophy the latter being opportunistic and tolerant to sulphide.
The Diversity of Deep-Sea Mussels and Their Bacterial Symbioses
Deep-sea chemosynthesis-based ecosystems are inhabited by diverse groups of metazoans. Although remote from the euphotic layer, and thus from photosynthetic primary producers, these ecosystems…
Several deep-sea mussels and their associated symbionts are able to live both on wood and on whale falls
TLDR
This study provides molecular-based evidence for the existence of two mussel species found both on sunken wood and bones, suggesting that habitat choice is independent of the symbiont localization.
