Shellfish areas usually receive a large number of introduced species. During the present project, we specially focused on 4 marine benthic molluscs introduced in shellfish areas along the Channel and Atlantic coasts of France: the gastropods Crepidula fornicata, Ocinebrellus inornatus and Cyclope neritea, and the bivalve Ruditapes philippinarum. Our study was conducted according to three main axes: (i) the characterization of introduction and expansion patterns of species within their newly colonized area. In the three invasive gastropods C. fornnicata, C. neritea and 0. inornatus, a high level of genetic diversity was detected in the French populations which indicated a complex process of introduction (with multiple population sources or secondary...
