Figure 2.

Kernel density plots for the five climatic variables, pH and two land cover variables for phenotypic categories (OVR and non‐OVR), nuclear genetic clusters (C1, C2, C3, and C4), and chlorotype genetic groups (A, B, and C). Underlined variable names indicate that OVR categories, nuclear genetic clusters or chlorotype genetic groups were distinguishable from each other, based on Cohen's d (Table S1), for that particular environmental variable. See codes for climatic variables in Table 2.
