3. Left panels: STRUCTURE results for Thuja plicata (western
redcedar) and Tsuga heterophylla (western hemlock), where each
bar indicates an individual in the population and the color indicates
the proportion of genetic variation associated to a particular cluster.
Clusters indicated by K values in the top right corner. Coastal
samples are denoted with a C in the label and inland samples with an I.
Right panels: Sampling localities plotted according to the proportion of
genomic variation attributed to each cluster, with clusters at K =
2 and K = 3.
