- Abstract
Solidago canadensis, considered one of the most destructive invasive species of the 21st century, has inflicted severe ecological damage globally. Nevertheless, the precise mechanisms through which nitrogen deposition impacts the metabolism of soil microorganisms across various vegetation communities remain largely unexplored. Consequently, this study sought to elucidate patterns of change in microbial metabolic constraints and carbon use efficiency across six distinct vegetation communities, aiming to uncover the carbon cycling process within soil ecosystems. Our findings reveal that multi-vegetation communities exhibit greater resilience to the incursion of Solidago canadensis than their single-vegetation counterparts, demonstrating weaker microbial carbon constraints and higher carbon use efficiency. Furthermore, a positive correlation was determined between microbial carbon use efficiency and carbon constraints. Driven by soil nutrients, nitrogen deposition synergistically interacts with Solidago canadensis, thereby influencing soil microbial carbon use efficiency. Thus, our experiment provides an initial perspective on the variations in metabolic limitations and carbon use efficiency amongst soil microbes across different vegetation communities. Such insights hold potential implications for future research focused on the feedback and responses of carbon cycles within varied vegetation community ecosystems to invasions in the context of increasing nitrogen deposition.
