Effects of country of origin (Country, C), temperature distance (Temperature.Distance, T), 5-azaC treatment (5-azaC), and their interactions on plant survival, biomass, and herbivory damage. N = 730 (survival), N = 403 (biomass, herbivory damage). D.f.: degrees of freedom. Significant values (p ≤ 0.05) are shown in bold. Estimates of the effects can be found in (Supporting Information, Supplementary Table S4).
