Percentage of change for response pools in (A) aboveground and (B) belowground variables.

An asterisk represents significant percentage of change with the N addition. A PR superscript represent a significantly different change between montane and lowland forests (ProRand ≤ 0.05). Bolded variables represent significant associated total heterogeneity (Qt; p ≤ 0.05). n represent the number of pair comparison between control and experimental N-supply.
