Figure 1

A map of the regions the tested genotypes of S. cerevisiae were isolated from and the strength of regional differentiation in the chemical profiles as indicated by F-statistics from pairwise PERMANOVA analyses (Supplementary Table S3).
Wider lines indicate weaker regional distinctions in the chemical profiles produced (i.e. less distinct chemical profiles), while thinner lines indicate stronger regional distinction (i.e. more distinct chemical profiles). The inset indicates the portion of NZ highlighted in the larger map. The outline of the map of NZ was obtained from www.spraypaintstencils.com, where it is freely available and all modifications were performed by the Authors in Microsoft Power Point.
