description: supplementary materials of manuscript "Overstory functional groups indicate the legacy of land use in a secondary tropical forest in southwestern China"Table S1. List of the overstory species with DBH ≥ 40 cm in the 20-ha Xishuangbanna tropical seasonal rainforest dynamics plot.Table S2. Dominant overstory species in different DBH classes of MRT groups. Only the species with a sum of importance ≤ 50% are listed when ranking the importance from high to low.Table S3. Load factors and contribution proportions of the first three PCA components.Fig. S1. Contrast and topography maps of the XTRDP. (a-c) represent the contrast of stretched BV in GLCM in 1965, 1981 and 2017, respectively; (d-j) represent CHM, DTM, slope, PAI, TWI, plan curvature and profile curvature, respectively. Colors from light to dark in (a-j) indicate data values from low to high. The red fishnet indicates the 50 m × 50 m subplot. Note that all maps were rotated clockwise 105 degrees from north for better visualization.Fig. S2. Graph of the relative error (RE, green line) and the cross-validated relative error (CVRE, blue line) of multivariate regression. The solution with the smallest CVRE is indicated (red point), as well as the CVRE error bars, and the red horizontal line is located one standard error above the minimal CVRE solution. The green bars indicate the number of times that the solution was selected as the best during the cross-validation iterations.Fig. S3. Multivariate regression tree for the importance of species at the top of the canopy (DBH ≥ 40 cm). All data in figure include explanatory variables (environmental factors) and response variables (importance of species) that were standardized in the MRT analysis, but the explanatory variables were restored to raw values in this figure for clarity. The height of the bar represents the importance of species.Fig. S4. Indicator species of the MRT groups.
