Widespread introgression in deep-sea hydrothermal vent mussels
Provedor de dados: 5
Autores: Breusing, Corinna; Vrijenhoek, Robert C.; Reusch, Thorsten B. H.
Background: The analysis of hybrid zones is crucial for gaining a mechanistic understanding of the process of speciation and the maintenance of species boundaries. Hybrid zones have been studied intensively in terrestrial and shallow-water ecosystems, but very little is known about their occurrence in deep-sea environments. Here we used diagnostic, single nucleotide polymorphisms in combination with one mitochondrial gene to re-examine prior hypotheses about a contact zone involving deep-sea hydrothermal vent mussels, Bathymodiolus azoricus and B. puteoserpentis, living along the Mid-Atlantic Ridge. Results: Admixture was found to be asymmetric with respect to the parental species, while introgression was more widespread geographically than previously...

A hybrid zone between Bathymodiolus mussel lineages from eastern Pacific hydrothermal vents
Provedor de dados: 5
Autores: Johnson, Shannon B.; Won, Yong-jin; Harvey, Julio B. J.; Vrijenhoek, Robert C.
Background: The inhabitants of deep-sea hydrothermal vents occupy ephemeral island-like habitats distributed sporadically along tectonic spreading-centers, back-arc basins, and volcanically active seamounts. The majority of vent taxa undergo a pelagic larval phase, and thus varying degrees of geographical subdivision, ranging from no impedance of dispersal to complete isolation, often exist among taxa that span common geomorphological boundaries. Two lineages of Bathymodiolus mussels segregate on either side of the Easter Microplate, a boundary that separates the East Pacific Rise from spreading centers connected to the Pacific-Antarctic Ridge.  Results: A recent sample from the northwest flank of the Easter Microplate contained an admixture of northern...
