摘要

Modifications to the invasion process of invasive plants may influence the functional dissimilarity between invasive and native plants, plant taxonomic and functional diversity, and the community invasibility. This study aimed to examine the ecological effects of the invasive tree Rhus typhina L. on the functional dissimilarity between R. typhina and native plants, plant taxonomic and functional diversity, and the community invasibility. Furthermore, this study assessed the contribution of R. typhina functional traits to its growth competitiveness as well as the relationships between the community invasibility and plant taxonomic and functional diversity under R. typhina-mediated invasion. This study employed a comparative field survey method in a wasteland located in a suburban area in northern China. A divergence in functional traits between R. typhina and native plants was observed. The plant supporting capacity and the leaf photosynthetic capacity of R. typhina were found to be significantly greater than those of native plants in the invaded communities. The leaf photosynthetic capacity of R. typhina may be a critical factor in determining its growth competitiveness. A negative correlation was observed between plant diversity and community invasibility in the invaded communities. Rhus typhina was associated with a reduction in plant diversity and richness, but an increase in the community-weighted mean trait values in the invaded communities.
