Intellectual Merit: Understanding species coexistence continues to be a fundamental goal in ecology with direct relevance to applied fields such as biodiversity conservation, resource management and restoration. For the practitioner of prairie restoration, knowledge of the different modes of coexistence and their relative importance in developing prairies would be valuable for guiding restoration prescriptions pertaining to site preparation, planting methods, invasive species control and management of disturbance regimes. This project initiates a long-term manipulative field experiment in eastern Kansas designed to evaluate multiple modes of species coexistence and plant community development, including the contributions of niche differentiation, functional similarity of species, spatial structure and initial community states in regulating native species establishment, diversity and species turnover in developing prairie restorations.Broader Impacts: The project will contribute to the development of the University of Kansas Field Station (KUFS) and complement ongoing research and education initiatives at KUFS in grassland ecology. The PI will continue to facilitate involvement of underrepresented groups through participation in KU student minority programs and provide training for two new PhD students. Undergraduates will participate as student hourly field assistants, KU independent study researchers and REU students. The project will also be utilized by students enrolled in KU Ecology courses and by AP Biology students at Lawrence High School.

智力优势：理解物种共存仍然是生态学的一个基本目标，与生物多样性保护、资源管理和恢复等应用领域直接相关。对于草原恢复的实践者来说，了解不同共存模式及其在开发草原中的相对重要性对于指导与场地准备、种植方法、入侵物种控制和干扰制度管理有关的恢复方案非常有价值。该项目在堪萨斯州东部启动了一项长期操控性田间实验，旨在评估物种共存和植物群落发展的多种模式，包括生态位分化、物种功能相似性、空间结构和初始群落状态在调节草原恢复发展中本地物种建立、多样性和物种更替方面的贡献。 更广泛的影响：该项目将有助于堪萨斯大学野外站（KUFS）和 补充 KUFS 正在进行的草原生态学研究和教育举措。 PI 将继续通过参与 KU 学生少数民族项目来促进代表性不足的群体的参与，并为两名新博士生提供培训。本科生将作为学生每小时现场助理、KU 独立研究研究人员和 REU 学生参与。该项目也将被 KU 生态学课程的学生和劳伦斯高中 AP 生物学的学生使用。
