Fig. 2 Functional dendrogram of the 18 dominant species inL. glaber–C. glauca evergreen broad-leaved forest community.
Fig. 3 Effects of topographic and edaphic variables on leaf functional traits and phylogenetic compositions at the community level. TP, TC, TN, TK: total soil phosphorus, nitrogen, carbon and potassium, respectively; AP, available phosphorus. Alt, Asp, Con, Slo: altitude, aspect, convexity, slope, respectively. (a) The effect of each variable (topography or soil) on community-weighted mean (CWMs) of leaf functional traits. (b) The effect of each variable (topography or soil) on phylogenetic compositions.
Fig.4 Variation partitioning of phylogenetic and functional traits structures (adjusted R2 × 100%) in the effects of different response variables at the community level . The interpretation rates of purely environmental (A), shared environmental and spatial (B) and purely spatial (C) fractions on different response variable are indicated by red, blue, and green, respectively. Response variables are the all community-level functional traits (Funtc), phylogenetic (Phyc) structures and each community-level traits composition.
