Geographic distribution of genetic diversity of mitochondrial and microsatellite markers. a Spatial distribution of two main mtDNA lineages, based on b median-joining haplotype network of 83 CYTB sequences (1124 bp) from 26 populations of the European bitterling. Length of branches in the network is proportional to the number of substitutions along a given branch (the number of substitutions in brackets for the main division), and circle size is proportional to haplotype frequency (reference scale provided). Colours of portions of pie-charts indicate the relative proportions of haplogroups at particular locations. c Overall geographic setting of the study area on the map of Europe, d microsatellite marker-based genetic structure of bitterling populations at the border of three watersheds. Colours of portions of in pie charts correspond with the inferred membership of individuals to a particular group K detected in STRUCTURE for K = 2; size of pie charts indicates allelic richness. River basins are illustrated using different colours. The map was created in QGIS 2.18 (http://qgis.org)
