Yihui Zhang, Guanmin Huang, Wenqing Wang, Luzhen Chen, Guanghui Lin. 2012. Interactions between mangroves and exotic Spartina in an anthropogenically disturbed estuary in southern China. Ecology 93:588–597.

Appendix B (TABLE B1). A table presenting density and vegetation structure of three dominant mangrove species along a salinity gradient in Zhangjiang Estuary in 2007. Plots were located in areas containing mangroves. Data were shown as means ± 1 SE. BSD = basal stem diameter (at 30 cm height). ND = no data (because the species was absent at that site). Data were analyzed with ANOVA followed by Tukey’s HSD tests.
