This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2022, Broadening Participation of Groups Underrepresented in Biology. The Fellowship supports a research and training plan for the fellow that will increase the participation of groups underrepresented in biology. Underneath the homogenous green exterior of plants lies a hidden world of complex chemical diversity. Variation in the chemical diversity of plants has significant ecological and evolutionary consequences, especially in a world shaped by human activity. Moreover, urbanization has radically changed the chemical environment experienced by plants due to pollution, agriculture, and land use. This research seeks to measure the effect of urbanization on the concentration of heavy metals and salts taken up by plants across urban-rural gradients in North and South America. Variation in plant chemical composition impacts food webs, especially interactions with herbivores and pollinators. Therefore, this research will elucidate how urban environments impact the chemical composition of local plant species and how they respond to urban pollutants. Additionally, this work will enhance basic plant knowledge as humans rely on plants for food, shade, and other ecosystem functions. The fellow is dedicated to training the next generation of underrepresented scientists through workshops, classes, and active recruitment and by bridging the gaps Latin American/Hispanic communities encounter in scientific literacy within and across the United States and Chile.This project aims to better understand how heavy metals and salts are distributed in plants across urban and rural areas and provide mechanistic insights into plant strategies for tolerating these elements. The fellow will tackle these goals by (1) performing a spatial and temporal sampling of plants found across urban-rural gradients, as well as using herbarium specimens found across historical urban gradients in the United States and Chile, and (2) examining whether plants with annual and perennial life cycles differ in their heavy metal and salt accumulation, regulation, and tolerance strategies using a common garden approach. This study will be the first to examine the spatial and temporal variation of heavy metals and salts in plants across urban gradients. It will serve as a foundation for linking plant chemistry to other ecological levels, including humans.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该行动为2022财年生物学的NSF博士后研究奖学金提供了资金，扩大了在生物学中代表不足的群体的参与。奖学金支持该研究员的研究和培训计划，这将增加生物学中代表性不足的群体的参与。植物的同质绿色外部下面是一个复杂化学多样性的隐藏世界。植物的化学多样性的变化具有重大的生态和进化后果，尤其是在人类活动所塑造的世界中。此外，由于污染，农业和土地利用，城市化已经从根本上改变了植物所经历的化学环境。这项研究旨在衡量城市化对北美北部和南美洲城乡占地植物所吸收的重金属和盐分的浓度的影响。植物化学成分的变化会影响食物网，尤其是与草食动物和传粉媒介的相互作用。因此，这项研究将阐明城市环境如何影响当地植物物种的化学组成以及它们对城市污染物的反应。此外，这项工作将增强基本的植物知识，因为人类依靠植物来用于食物，阴影和其他生态系统功能。该研究员致力于通过研讨会，课程和积极的招聘培训下一代代表性不足的科学家，并通过弥合差距，在美国和智利的科学素养中遇到的拉丁美洲/西班牙裔社区遇到的差距。该项目的旨在更好地了解重金属和盐在工厂中如何在工厂中分布在工厂中，并将其分布在工厂中，并将其分布在工厂中，并将其分布在工厂中。该家伙将通过（1）对在城乡梯度中发现的植物进行空间和时间采样来解决这些目标，并使用在美国和智利的历史城市梯度中发现的植物标本室标本，以及（2）检查具有年度和多年生生命周期的植物是否在其重金属和盐分中使用的较重的金属和境地，使用常见的花园策略在每年和多年生生命周期中是否有所不同。这项研究将是第一个检查城市梯度植物中重金属和盐的空间和时间变化的研究。它将成为将植物化学与其他生态水平联系起来的基础，包括人类。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响标准，被认为值得通过评估来获得支持。
