| Résumé : |
Populations of Clownfish species often show signs of local isolation due limited dispersal potential and sea surface currents. On top of that, anthropogenic pressure such as overharvesting and reef exploitation triggers them from reduced population size, eventually leading to local extinction. The understanding of genetic population structure, as well as the influence of both historical lineages and current connectivity, is required to design effective conservation plans and properly protect these species. In this study, the genetic structure of Clark's Anemonefish (Amphiprion clarkii) populations of the Indo-Malay Archipelago (IMA) is assessed through genetic markers. Demographic quantities such as gene flow, population effective size and divergence time were also estimated for four [...] Populations of Clownfish species often show signs of local isolation due limited dispersal potential and sea surface currents.

Results provided evidence of a clear genetic structure [...] and best supported regional groupings [...] |
