入侵与本地植物竞争响应全球变化主要因子协同作用及其系统生态机制

如何应对包括生物入侵的全球变化是人类社会共同面临的重大挑战。怎样科学预测全球变化对生物入侵的影响？其关键在于阐明入侵与本地生物竞争对全球变化主要多驱动因子协同作用的响应及其机制！这不仅是世界各国国家重大需求，(五个及以上因子的协同效应)更是世界科技空白！基于前期基础，我们开创性明确提出全球变化主要因子协同作用于入侵与本地植物竞争的亚加和效应及其系统生态机制假说。并基于我们多学科学术背景及前期基础与技术平台，构建全球变化多因子协同作用研究新思路，综合生物、生态、化学、地球科学等研究进展，特别整合组学理论、方法和技术等，创新设计并实施系统、科学的全球变化主要因子协同作用于植物竞争的叠连实验研究体系，以期证明上述假说。项目不仅对发展入侵生态学核心理论具有根本性重要意义；也能在实践上更科学、准确预测全球变化下的生物入侵；还可为多因子协同作用及机制研究提供参考；并力争在这一学科方向成为国际领跑者。

A major challenge for human society is dealing with global changes, including biological invasions. Predicting the influence of global changes on biological invasions is not only a significant need around the world, but also represents a major gap in science and technology. The key is to identify the response and mechanisms of competition between invasive and native species to global changes. Based on preliminary research, we propose the following hypothesis: synergistic effects of major factors of global changes on competition between invasive and native species are sub-addictive to invasive species; And we predict that synergistic effects favor invasive species via ecological mechanisms, either directly through gene expression and regulating anabolism, catabolism, hormones and their functions; or indirectly affecting plant growth and development by changing plant endophytes, allelopathy and soil microorganisms. Based on our multidisciplinary academic background, preliminary foundation and technical platform, we will test the above hypothesis by developing new ideas for multi-factor research into global change synergies, integrating advances in biology, ecology, chemistry and earth sciences etc., with a particular focus on omics techniques, innovative experimental design, and performing systematic and scientific iterative experiments to investigate synergistic effects of major factors of global changes on plant competition. Such an approach is not only of fundamental significance to the development of the core theory of invasion ecology,but is also important for predicting biological invasions under global changes in practice,and provides reference for research on multi-factor synergy and mechanisms. And we will strive to become an international leader in this discipline direction.
