Gamma diversity patterns of tree species and non-tree species of the different communities. The graphs show species richness (Hill number q = 0, including 95% confidence interval). Red: all four communities, Yellow-green: Saraca dives + Calamus tetradactylus community (SCt), Green: Sterculia lanceolata + Chloris barbata community (SCb), Light-blue: Ficus superba + Acanthus ebracteatus community (FAe), Pink: Clausena excavata + Desmos cochinchinensis community (CDc). For Hill numbers q = 1 and q = 2, see Appendix 6. Graphs were extrapolated to a sample size of 90 plots.
