Fig. 2. The proportion of variation explained (mean ± SD) by pure canopy structure difference, pure environmental distance, and pure spatial distance at each of three sampling scales for all woody plant individuals (DBH ≥ 1 cm) on beta diversity based on each of 11 functional traits in the 20 ha forest dynamics plot in the Xishuangbanna tropical seasonal rainforest. Different letters indicate significantly difference at P < 0.05.
