All traditional markers, both phenotypic and
phylogenetic, have failed to discriminate between
the taxa composing the Fucus vesiculosus L., F. spiralis
L., and F. ceranoides L. species complex, particularly
in Brittany (France), so we used five microsatellite
markers to compare the allelic frequencies of popu-
lations of the three taxa in this region. The aim of
this study was to assess whether the different popu-
lations were grouped according to their geographical
