a Principal Components Analysis of the microsatellite markers for all the populations of N. fulva sampled. b Graphical representation of STRUCTURE results for different values of K genetic groups using the entire dataset (n = 937; N = 63 nests). Simulation using a single individual per nest gives similar results (Additional file 1: Figure S1). Each group is characterized by a color; and each individual is represented by a vertical bar according to its probability to belong to each group. A different simulation was run for our overall sampling and then for both native and introduced ranges separately. c Haplotypes network for the COI mitochondrial marker of N. fulva in its native and introduced populations. Circle sizes are proportional to the number of sequences observed in the dataset and branch lengths indicate the number of mutations between haplotypes. N. terricola is used as an outgroup
