| Aim Deep-sea hydrothermal vents have now been reported along all active mid-ocean ridges and back-arc basins, but the boundaries of biogeographic entities remain questionable owing to methodological issues. Here we examine biogeographic patterns of the vent fauna along the East Pacific Rise (EPR) and determine the relative roles of regional and local factors on the distribution of biodiversity associated with mussel beds along a poorly explored zone, the southern EPR (SEPR). Location East Pacific Rise. Methods A species list of macrobenthic invertebrates along the EPR was compiled from the literature and supplemented with data recovered during the French research cruise BIOSPEEDO carried out in 2004 along the SEPR. Biogeographic patterns were assessed by... |

| The brittle star Ophiothrix fragilis (Abilgaard, 1789) constitutes a heterogeneous morphological group that can be subdivided into 4 varieties. The species is also characterized by high demographic variability. The present study explores the possibility of genetic patchiness arising due to admixture of varieties or recruitment heterogeneity. We sequenced a portion of the mitochondrial cytochrome oxidase subunit I (mtCOI) gene and genotyped 7 allozymes from 21 populations of the 2 most common varieties. While mtCOI analyses showed that all the varieties grouped together with virtually no divergence among them (< 1%), a clear divergence (18.6%) was evident between the northern Atlantic populations and individuals collected in the Mediterranean and along... |
