Fig 1.
Sample distribution and location of the pre-defined study populations.
The size of a circle is representative of the number of samples collected from that locality.
Fig 2.
Geographic distribution of the BAPS derived clusters (K = 3), obtained using the spatial model.
Different colours represent the model assignment of individuals to the different clusters. The size of the symbol is representative of the number of individuals sampled at that location (see also Fig 1). Inset: Summary of the assignment results obtained with STRUCTURE (K = 2 to 4) and BAPS (K = 3). Each individual is represented by a single vertical line, representing the individual`s estimated proportion of membership to the genetic cluster. Colours correspond to the clusters in the main figure. The order of the individuals was the same in both assignments. The STRUCTURE K = 4 bar chart represents results from the nine (out of ten) independent runs that converged on the same clustering solution.

Factorial correspondence analysis of raccoon dogs from the 10 pre-defined European populations.
The analysis was based on 15 microsatellite loci. The percentage of the total variation explained by each of the two axes is given.
Fig 4.
Genetic and geographic distance for pairs of sampled pre-defined populations.
Genetic differentiation is given as FST/(1-FST), whereas the geographic distance was log-transformed. Geographic distances are given as effective geographic distances that only consider the shortest overland route between sampling points.
