Table 2 Associations between principal component (PC) axes of environmental variation and UV resistance, split by treatment. Reported statistics are from multi-way ANOVA models that include a PC (d.f. = 1) and species (d.f. = 2) as independent variables, and a given physiological trait as the dependent variable. Bonferroni corrected significance level is P < 0.0004
