Genetic structures and evolutionary histories of polychaetes inhabiting muddy-fine sediments in the North East Atlantic : Pectinaria sp. and Owenia sp.
With respect to the large scale patterns of geographic distribution of bentho-pelagic marine species and their conservation, predicting the fate of biological systems passes by the understanding of past processes linked to the evolutionary history of species, associated with life history traits and...

With respect to the large scale patterns of geographic distribution of bentho-pelagic marine species and their conservation, predicting the fate of biological systems passes by the understanding of past processes linked to the evolutionary history of species, associated with life history traits and functioning of their populations over geological time scales. The evolution of any species cannot be fully understood without integrating evolutionary processes working at all spatial (from a patch to the species' geographical range) and temporal scales (from one generation to the resilience of the species). considering such a framework, we used enzymatic markers, mitochondrial gene sequences of the Cytochrome Oxidase subunit I (mtCOI), and microsatellite loci to (1) investigate past colonisation pathways on an evolutionary timescale in Pectinaria sp. and Owenia sp., with respect to the geological history of the North East Atlantic, (2) identify contemporary gene flow in the English Channel/ Irish Sea between populations of Pectinaria koreni, by comparing genetic patterns with those estimated from hydrodynamic modelling of larval dispersal in the English Channel, and (3) assess the micro-evolutionary processes shaping the spatio-temporal structure of the local metapopulation of P. kereni in the Baie de Seine.
