Estimated number of populations from Structure (a and b) and Geneland (c and d) analyses. Structure analyses: (a) mean (± SD) probabilities of the data [LnPr(X|K)] over 10 Structure replicated runs plotted as a function of the putative number of clusters (K). (b) Mean variations of probabilities of the data (Δ(LnPr(X|K)) between successive K considered in Structure analyses. For K clusters, this variation is calculated as Δ(LnPr(X|K))=LnPr(X|K)
. Geneland analyses: posterior density distribution of the number of clusters estimated from Geneland analysis in 7 out of 10 replicates (c) and in the 3 remaining trials (d).
