This action funds Steven Thomas Callen of Saint Louis University to conduct a research project in Biological Sciences during the summer of 2013 at the Kunming Institute of Botany in Kunming, Yunnan, China. The project title is "A comparative analysis of floral reproductive traits between native and introduced kudzu (Pueraria montana)." The host scientist is Dr. Hong Wang.The ability of invasive plant species to reproduce in new environments may be limited by the availability of compatible mates and pollinators. In such situations, shifts in plant mating systems (for example, from outcrossing to self-fertilization) may promote invasion by providing enhanced fruit and seed production. Current understanding of mating system shifts during invasion is limited, particularly for perennial (long-lived) invaders that reproduce both sexually and clonally. In this study, the Fellow uses the vine kudzu (Pueraria montana), one of the most potent plant invaders in North America, as a model to investigate the consequences of invasion for the mating systems of perennial, clonal plants. The reproductive biology (pollinator and pollen availability and its capacity for fruit/seed set and self-fertilization) from its native range (China) to that from its introduced range (North America) are compared.Broader impacts of an EAPSI fellowship include providing the Fellow a first-hand research experience outside the U.S.; an introduction to the science, science policy, and scientific infrastructure of the respective location; and an orientation to the society, culture and language. These activities meet the NSF goal to educate for international collaborations early in the career of its scientists, engineers, and educators, thus ensuring a globally aware U.S. scientific workforce. Furthermore, this study supplements other comparative studies of plant invasions among China and North America to identify common factors driving invasion success between the two countries. Photos and videos will be integrated with the knowledge and results generated from this fellowship for presentations at national and international scientific meetings, reports for conservation organizations, and teaching activities. Establishing international collaborations allows the Fellow to connect undergraduate and high school students with Chinese researchers through video conferencing, helping to expand student concepts of scientific research to a global view.

这项行动资助圣刘易斯大学的史蒂文托马斯卡伦在2013年夏天在中国云南昆明的昆明植物研究所进行生物科学研究项目。 项目名称为“本地和引进野葛花繁殖性状的比较分析”。“主办科学家是王宏博士。入侵植物物种在新环境中繁殖的能力可能会受到兼容配偶和传粉者的限制。 在这种情况下，植物交配系统的转变（例如，从异交到自花受精）可能会通过提高果实和种子产量来促进入侵。 目前对入侵过程中交配系统变化的理解是有限的，特别是对于有性繁殖和克隆繁殖的多年生（长寿）入侵者。 在这项研究中，研究员使用了北美最强大的植物入侵者之一的葛属植物（Pueraria montana）作为模型，以调查入侵对多年生克隆植物交配系统的影响。 比较了其原产地（中国）和引进地（北美）的生殖生物学（传粉者和花粉的可用性及其结实/种子结实和自花受精的能力）。EAPSI奖学金的更广泛影响包括为研究员提供美国以外的第一手研究经验;介绍各自所在地的科学，科学政策和科学基础设施;以及社会，文化和语言的方向。 这些活动符合NSF的目标，即在科学家，工程师和教育工作者的职业生涯早期进行国际合作教育，从而确保具有全球意识的美国科学工作者。 此外，这项研究补充了中国和北美之间的植物入侵的其他比较研究，以确定两国之间的入侵成功的共同因素。 照片和视频将与该奖学金产生的知识和成果相结合，用于在国家和国际科学会议上进行演讲、为保护组织提供报告以及教学活动。 建立国际合作使研究员能够通过视频会议将本科生和高中生与中国研究人员联系起来，帮助将学生的科学研究概念扩展到全球视野。
