英文摘要 | 1. Anthropogenic environmental changes are known to affect the Earth's ecosystems. However, how these changes influence assembly trajectories of the impacted communities remains a largely open question. 2. In this study, we investigated the effect of elevated nitrogen (N) deposition and increased precipitation on plant taxonomic and phylogenetic beta-diversity in a 9-year field experiment in the temperate semi-arid steppe of Inner Mongolia, China. 3. We found that both N and water addition significantly increased taxonomic beta-diversity, whereas N, not water, addition significantly increased phylogenetic beta-diversity. After the differences in local species diversity were controlled using null models, the standard effect size of taxonomic beta-diversity still increased with both N and water addition, whereas water, not N, addition, significantly reduced the standard effect size of phylogenetic beta-diversity. The increased phylogenetic convergence observed in the water addition treatment was associated with colonizing species in each water addition plot being more closely related to species in other replicate plots of the same treatment. Species colonization in this treatment was found to be trait-based, with leaf nitrogen concentration being the key functional trait. 4. Synthesis. Our analyses demonstrate that anthropogenic environmental changes may affect the assembly trajectories of plant communities at both taxonomic and phylogenetic scales. Our results also suggest that while stochastic processes may cause communities to diverge in species composition, deterministic process could still drive communities to converge in phylogenetic community structure. |
