Simulated scenario and main observed STRUCTURE patterns at K = 2. a Graphical representation of the simulated scenario in which two invasive populations (populations 2 and 3) are independently derived from the native population (population 1). N is the effective size at equilibrium and NF is the effective number of founders during the bottlenecks. b Schematic representations of the main patterns obtained in the STRUCTURE runs for K = 2 and their associated summarized codes. The misleading pattern, inconsistent with the simulated scenario, is boxed. c Five examples of clusterings obtained over ten STRUCTURE runs for K = 2, and their associated classification. In this study, we focused on “misleading homogeneous clusterings” and “misleading heterogeneous clusterings”, in which “misleading patterns” were found in all ten runs or predominated, respectively, for a given dataset. Runs displaying the misleading pattern are boxed
