Functional group identity and diversity of resident wetland plant communities are good predictors of biotic resistance to invasion by an introduced lineage of Phragmites australis, suggesting niche pre-emption (priority effect) and niche partitioning (diversity effect) as underlying mechanisms. Guiding principles to understand and/or manage biological invasion could emerge from advances in community theory and the use of a functional framework. Targeting widely distributed model invasive species, such as P. australis, could facilitate generalization in invasion ecology and functional ecology.
