Figure 3
Distribution of W-Palearctic tree frogs based on genetically barcoded populations, combining 25 studies. At transitions, populations were considered as a mix (represented in half circles) if they featured both mtDNA haplotypes and/or nuclear genotypes consistent with admixture (STRUCTURE’s Q < 0.9 in multilocus analyses; co-segregation of species-diagnostic alleles). The map was created in QGIS 3.4 (https://qgis.org). Photo: Hyla meridionalis from southeastern France, by CD.
