Summary of the clustering results for European mink populations obtained using STRUCTURE. (a) Detecting the number of populations as a function of the highest posterior probability (mean LnP[D]) over the number of clusters k (k = 4). (b) Each individual is represented as a vertical line partitioned into k segments whose length is related to their membership proportions to each inferred k cluster. The subdivision according to sampling localities (dataset I) or drainage distribution (dataset II) is also specified in the figure
