Gene expression clustering of samples of Argentine ants in their native and introduced ranges, based on multi-dimensional scaling of TMM-normalised counts per million (CPM) with low expressed transcripts filtered out. Euclidian distances between samples are computed from genes with the largest standard deviations. Regions are indicated as Argentina (AR), California (CA), Europe (EU), Australia (AU) and New Zealand (NZ) and collection site shown as subscript (details in Suppl. material 1: Table S1).
