The phylogenetic signal was significant when K < 1.00 and P < 0.05.

N nitrogen, eCO₂: elevated carbon dioxide concentration, [C]: carbon concentration, [N]: nitrogen concentration, [P]: phosphorus concentration, foliar CN: foliar carbon to nitrogen ratio, foliar NP: foliar nitrogen to phosphorus ratio, NRE: nitrogen resorption efficiency, PRE: phosphorus resorption efficiency.
