| Fig. 5 Relative influence of different variables on the ecological uniqueness of plant communities. (a) Parameter estimates and the associated 95% confidence interval of each variable that enters into final models; (b) The explanation of longitude, soil and climate, community characteristics (species richness and plant community coverage) to the ecological uniqueness of plant communities. SR, Species richness; PCC, Plant community coverage; SM, Soil moisture; TSN, Soil total nitrogen content; pH, Soil pH; MAT, Mean annual temperature; PS, Precipitation seasonality. ***, P < 0.001. |
