Figure S1 . ΔK values for different numbers of populations
assumed (K) in the STRUCTURE HARVESTER analysis v 0.6.94 for the six
population groups of Jubaea chilensis , central Chile.
Figure S2 . Populational structure inferred for the six sampled
groups of Jubaea chilensis , central Chile, based on the analysis
of 1,038 SNPs using the STRUCTURE v 2.3.4, assuming the Admixture model.
Each individual is represented by a vertical bar, often partitioned into
colored segments with the length of each segment representing the
proportion of the individual’s genome from K = 3 ancestral populations.
Cocalan:1-24, Culimo:25-50, Viña del Mar/Valparaíso:51-74,
Candelaria:75-96, Petorca:97-115, and Ocoa:116-140.
Table S1 . Evanno method results (Evanno et al., 2005) obtained
using the STRUCTURE HARVESTER v 0.6.94 for the six population groups ofJubaea chilensis , central Chile. The highest value of delta K (in
bold) indicates the number of established groups.
