Figure 3. STRUCTURE analysis.
(a) The Evanno method implemented in STRUCTURE HARVESTER35 suggests that the most likely number of common cuckoo Cuculus canorus genetic groups in Europe is K=3 based on 13 microsatellite markers and 104 individuals. (b) Individual and (c) population Q matrices for the three genetic groups show little evidence that this putative population structure is related to either host race or the divergent mitochondrial lineages.
