Figure 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.
