Patristic distances calculated based on phylogenetic trees for the SSU and SSU + ITS rRNA gene sequences of Amphistegina lobifera including all genotypes (a) and beta dispersion analysis of intra-genomic distances within invasive genotype Ia: by oceanic basin (b, top panel) and by status of invasion in the Mediterranean Sea (b, bottom panel). Stars represent levels of significance in the Wilcoxon test shown in Table 3.
