Relative canopy height profiles for 50 m bins across altitudinal gradients on zonal soils on sedimentary rock, Quaternary sediments and granite (upper panels) vs. azonal soils underlain by ultrabasic rocks (lower panels) on Mount Kinabalu. Horizontal bars and lines represent the mean and standard errors, respectively. Plots with asterisks are mixed forests with conifer relative basal area >25 %. The coefficient of skewness (CS) is shown for each plot.
