Number of nests sampled, location and descriptive population statistics (mean ± se and [95% confidence interval]) for genetic and chemical analyses of eight Cameroonian populations of the invasive ant P. megacephala.

†Mean ± se population genetic statistics over eight loci. A: number of alleles; Ar: allelic richness; H: gene diversity; f: inbreeding coefficient; r: relatedness; Fst: Wright's measure of population subdivision; I: Nei index; E: Euclidean distance. Statistical comparisons between ecological zones were conducted using non-parametric, Mann-Whitney tests (different letters indicate significant differences).
