a
Distance values, computed with PAUP*, between sequences of the ITS1-5.8S-ITS2 rDNA region obtained from nine strains of Alexandrium spp., which grouped together in a cluster as a result of a phylogenetic analysis (Clade 1 in Fig. 3). Uncorrected distances are given above the diagonal and distance estimates based on the Kimura-2 parameter model are given below the diagonal.
