Phylogeny and distribution of Gammarus roeselii COI BINs: (a) Bayesian tree reconstructed from representative sequences of all COI BINs with MOTUs definition. MOTUs were defined after Grabowski et al.11. BINs produced in this study are indicated by frames. Values at nodes indicate the bootstrap values (above 0.5) for the parallelly reconstructed ML tree. (b) Map showing all sampling sites of the study. Colours indicate BINs of A. Triangles indicate sampling sites of sequences from Grabner et al.49. Black dots represent the sites from Grabowski et al.11, displaying also the COI MOTUs found in the Balkan Peninsula. (c & d) Haplotypic networks of COI and ITS2 markers, respectively. Colour codes indicate COI BINs. Stars on the ITS2 network indicate ITS2 haplotypes which were present in northern Italy. Map created with QGIS 3.4.5 (https://www.qgis.org/fr/site/).
