AbstractPI: Siemann and Rogers Institution: William Marsh Rice University Proposal Number: DEB-9981654The alien Chinese Tallow Tree is a major invader in the Gulf Coast which aggressively displaces native plants. This research will focus on understanding the mechanisms that allow this species to establish in a broad range of Gulf Coast ecosystems (urban habitats, prairies, hardwood forests and floodplain forests), to out-compete and displace native vegetation, and to maintain self-replacing monocultures. Experiments will be replicated across major landscape types to examine: (1) the relationship between severity of alien plant invasion and lack of herbivores and diseases; (2) the importance of resource alterations in governing invasion severity; and (3) how local recruitment limitation affects alien plant invasion. Understanding the mechanisms of plant invasion is critically important to both society, with increasing economic and political impacts of alien species, and ecology because invasion plays a key role in community development and ecosystem function.

摘要PI： Siemann & Rogers Institution： 威廉·马什·赖斯大学 提案编号：DEB-9981654外来的乌桕树是墨西哥湾沿岸的主要入侵者，它积极地取代本土植物。这项研究将侧重于了解允许该物种在墨西哥湾沿岸广泛的生态系统（城市栖息地，草原，硬木林和洪泛区森林）中建立的机制，以竞争和取代原生植被，并保持自我替代的单一栽培。实验将在主要景观类型中重复进行，以研究：（1）外来植物入侵的严重程度与缺乏食草动物和疾病之间的关系;（2）资源改变在控制入侵严重程度方面的重要性;以及（3）当地补充限制如何影响外来植物入侵。 了解植物入侵的机制对社会和生态都至关重要，因为入侵在群落发展和生态系统功能中起着关键作用。
