Temporal genetic variation in european eel anguilla anguilla (linnaeus, 1758): A fine scale investigation in the adour estuary
Résumé
The genetic structure of arrival cohorts of European eels in the continental basin of Adour, France, was analysed. A regular sampling was carried out during three successive seasons of migration to ensure a representative sampling of complete recruitment in the estuary. Genetic variability within this sample was evaluated by analysis of highly polymorphic microsatellite markers. A high level of polymorphism was highlighted but a lack of genetic differentiation was observed between cohorts collected during the three successive seasonal migrations. © 2011 Taylor & Francis.
