Species Trait Differences When the populations sampled were grown in a common garden, the two species exhibited highly significant ( p < 0.001) differences in growth performance measures, as well as in most leaf economic and hydraulic traits ( Table 1 ).
ovata populations was marginally significant ( p = 0.021) but not significant in E. pauciflora ( p = 0.152).
ovata, population differentiation in leaf traits was marginally nonsignificant ( p ≤ 0.1) on the first maximum variance axis (LD1 42.4%, p = 0.081; LD2 21.8%, p = 0.690), whereas in E. pauciflora statistically significant differentiation occurred in two independent directions (LD1 42%, p < 0.001, and LD2 23.4%, p = 0.045) ( Figure 1 ).
