Shekhar R. Biswas and Azim U. Mallik. 2010. Disturbance effects on species diversity and functional diversity in riparian and upland plant communities. Ecology 91:28–35.

Appendix D. Mean (±SD) number of species per functional traits under different intensity of disturbances. The results of nested ANOVA with disturbance and habitat as fixed factors and site as random factor. P value indicates the disturbance effects. Trait marked with * indicates that differed significantly at α = 0.05 and traits marked with ♣ indicates significant interactions effect (i.e., disturbance – habitat stability coupling).
