Abstract: | Microsatellite markers have been used to study the genetic variability of rainbow wrasse (Coris julis) Mediterranean and Atlantic populations. Differentiation tests failed to reveal any significant genetic differentiation among samples from continental Portugal and the Azores, despite more than 1800 km of geographical separation. Preliminary results tended to indicate a significant genetic differentiation among Atlantic and Mediterranean samples. It also supported the specific status of Cape Verde populations (Coris atlantica). We compare these results with previous mtDNA analyses and propose a biogeographic scenario that could explain our results. |
