After publication of this work, Johannes noted a mistake occurring in Table 1, Figure 1, Figure 2, Figure 4 and on page 6 (Result section). In these places of the article, we wrote that the two brown trout samples of the Mediterranean (ME) lineage came from Sardinia, which is not the case. These two samples of the ME lineage were taken from the small river Caranca, a tributary to the Tet River in France and this lineage carried a single mtDNA haplotype MEcs3. Samples were provided by Patrick Berrebi.
This information could be much misleading for those who study Mediterranean trout given that only AD and AT haplotypes have been found in Sardinian rivers so far.
The authors thank Johannes for pointing out the mistake and apologize for this awkwardness.
