项目摘要
As human activity increasingly impacts the natural world, informed decisions must be made about how to manage and restore natural systems. Recent and widespread declines in milkweed plant populations are causing alarm, in large part because milkweeds are a critical food source for vulnerable populations of the iconic monarch butterfly. Milkweed restoration efforts have been initiated; however, the influence of seed source on subsequent plant growth and survival is unknown. For example, if milkweeds are locally adapted to specific climates or soil types, then moving them from one region to another could be problematic. This project will engage educators and their students from across the range of common milkweed in investigations to document patterns of local adaptation and to identify the environmental factors influencing the evolution of the species. The data gathered through this project should improve recommendations for how to select seeds for milkweed restoration projects. At the same time, researchers will document the impact of participation in this project on student learning and motivation in science. The collaboration between researchers, educators, and students will allow scientists to sample more populations than they could otherwise study while engaging students in authentic research experiences.In this project, researchers will use a variety of methods to investigate biotic and abiotic factors that affect the patterns of local adaptation in common milkweed. First, they will support educators and students at about 30 different institutions to study patterns of adaptation in experimental gardens planted at each site, and they will work to expand this network to engage more educators and students in relevant observational data collection. Educators will meet to improve and share lesson plans and to integrate new protocols into the curriculum. Second, they will plant three large experimental gardens at sites in Minnesota, Ohio, and Virginia to identify which milkweed traits most affect fitness in each environment at different life stages. At these three sites, they will not only study soil and climate related factors, but they will also observe pollinators and manipulate access to plants by herbivores to better understand the relative importance of these different factors on the evolution of milkweed traits across populations. Third, they will gather genetic data for plants from each population to compare the patterns of natural selection on traits to the patterns of genetic diversity. In addition to integrating these approaches for studying local adaptation, researchers will assess the impact of engaging educators and students in the research process, including evaluating student learning of important scientific skills and concepts and measuring student motivation to study science.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.
随着人类活动对自然界的影响越来越大,必须就如何管理和恢复自然系统做出明智的决定。最近乳草植物种群的普遍下降引起了人们的警觉,这在很大程度上是因为乳草是标志性帝王蝶脆弱种群的重要食物来源。乳草恢复的努力已经开始,但是,种子来源对随后的植物生长和生存的影响是未知的。例如,如果乳草在当地适应特定的气候或土壤类型,那么将它们从一个地区转移到另一个地区可能会有问题。该项目将使来自各种常见马利筋的教育工作者及其学生参与调查,以记录当地适应的模式,并确定影响该物种进化的环境因素。通过这个项目收集的数据应该改善如何选择种子乳草恢复项目的建议。同时,研究人员将记录参与该项目对学生学习和科学动机的影响。研究人员、教育工作者和学生之间的合作将使科学家能够对更多的种群进行采样,同时让学生参与真实的研究体验。在这个项目中,研究人员将使用各种方法来调查影响普通马利筋当地适应模式的生物和非生物因素。 首先,他们将支持大约30个不同机构的教育工作者和学生在每个地点种植的实验花园中研究适应模式,他们将努力扩大这一网络,让更多的教育工作者和学生参与相关的观测数据收集。教育工作者将开会改进和分享课程计划,并将新的协议纳入课程。 其次,他们将在明尼苏达州、俄亥俄州和弗吉尼亚州的三个地点种植三个大型实验花园,以确定在不同的生命阶段,哪些马利筋的特征对每种环境中的适应性影响最大。在这三个地点,他们不仅将研究土壤和气候相关因素,还将观察传粉者,并操纵食草动物对植物的访问,以更好地了解这些不同因素对乳草种群特征演变的相对重要性。 第三,他们将从每个种群中收集植物的遗传数据,以比较性状的自然选择模式和遗传多样性模式。除了将这些方法用于研究当地适应情况外,研究人员还将评估让教育工作者和学生参与研究过程的影响,包括评估学生学习重要的科学技能和概念,衡量学生学习科学的动机。该奖项反映了NSF的法定使命,并被认为值得通过使用基金会的智力价值和更广泛的影响评估来支持的搜索.
