Génétique des populations de bivalves en milieu lagunaire: la palourde dans l'étang de Thau (Méditerranée)
Provedor de dados: 5
Autores: Borsa, Philippe.
The genetic structuration of populations of the palourde, Ruditapes decussatus, a bivalve species of the Mediterranean coastal lagoons, was studied at the enzymatic gene level, in relation to their ecology and their demography. A genetic comparison of local populations of the Languedocian lagoons suggested that they constitute a metapopulation. In the Thau lagoon, genetic heterogeneity could be related to demographic features. Genetic differences between cohorts appeared to account for significant heterozygote deficiencies, although not fully explaining them. For this, a Wahlund effect could be rejected. The hypothesis of selection affecting pre-recruits appeared most likely and it was confirmed by preliminary results of experiments conducted on larvae. It...

Genome scans discriminate independent populations of the blue shark Prionace glauca

The blue shark Prionace glauca is a cosmopolitan species that inhabits all oceans worldwide except the poles. Several IUCN regional assessments have classified   it as Near Threatened, mostly due to overfishing. Previous genetic studies that have used classical genetic markers failed to reject the hypothesis that the species is a single worldwide population (panmixia). As such, the blue shark was proposed to be an archetype of the ‘grey zone of population differentiation’, named to signify those cases common in the marine realm, where the split among population is too recent or too faint to be detected using classical genetic markers. Here, samples collected across the majority of the global range of blue shark were sequenced (using a specific genome scan...

Mitochondrial phylogeny of grey mullets (Acanthopterygii: Mugilidae) suggests high proportion of cryptic species
Provedor de dados: 5
Autores: Durand, Jean-dominique; Borsa, Philippe.
The low level of morphometric variability and the poor phylogenetic information borne by the morpho-anatomical characters used thus far in the systematics of grey mullets (Mugilidae) emphasize the utility of molecular systematics in this family. A recent mitochondrial phylogeny of grey mullets has uncovered multiple deep lineages within several species, flagging putative cryptic species. Here, we considered that several of the deeply divergent lineages represent separate species based on either the tree topology, independent data from nuclear markers, geographic distributions, or a combination of the foregoing. By analogy with these well-documented cases, we considered other deep lineages in seven genera we focused on to represent putative cryptic species....

Biodiversity inventory of the grey mullets (Actinopterygii: Mugilidae) of the Indo‐Australian Archipelago through the iterative use of DNA‐based species delimitation and specimen assignment methods

DNA barcoding opens new perspectives on the way we document biodiversity. Initially proposed to circumvent the limits of morphological characters to assign unknown individuals to known species, DNA barcoding has been used in a wide array of studies where collecting species identity constitutes a crucial step. The assignment of unknowns to knowns assumes that species are already well identified and delineated, making the assignment performed reliable. Here, we used DNA‐based species delimitation and specimen assignment methods iteratively to tackle the inventory of the Indo‐Australian Archipelago grey mullets, a notorious case of taxonomic complexity that requires DNA‐based identification methods considering that traditional morphological identifications...

Comparative phylogeography of the western Indian Ocean reef fauna
Provedor de dados: 5
Autores: Borsa, Philippe; Durand, Jean-dominique; Chen, Wei-jen; Hubert, Nicolas; Muths, Delphine; Mou-tham, Gerard; Kulbicki, Michel.
Assessing patterns of connectivity at the community and population levels is relevant to marine resource management and conservation. The present study reviews this issue with a focus on the western Indian Ocean (WIO) biogeographic province. This part of the Indian Ocean holds more species than expected from current models of global reef fish species richness. In this study, checklists of reef fish species were examined to determine levels of endemism in each of 10 biogeographic provinces of the Indian Ocean. Results showed that the number of endemic species was higher in the WIO than in any other region of the Indian Ocean. Endemic species from the WIO on the average had a larger body size than elsewhere in the tropical Indian Ocean. This suggests an...
