Title: Collaborative Research: BoCP-Implementation: Integrating Traits, Phylogenies and Distributional Data to Forecast Risks and Resilience of North American PlantsApproximately 38,000 species of seed plants in North America are assembled into an array of communities that reflect diversity in geology and climate, and which have dynamic evolutionary histories. These species represent approximately 22% of the world’s seed plant flora and an enormous range of ecologies and traits. Despite considerable effort, we lack an understanding of why some lineages and regions seem to be more resilient than others in response to accelerating climate and land use changes. With this study, we will conduct a continent-wide examination of the diversity of seed plants, along with their patterns of distribution - past, present, and future. The resulting information will be essential for predicting and modeling the resilience of lineages and communities in the face of rapid global change. Central to this research will be an examination of plant traits and their evolutionary histories, which together will provide new means to assess what has shaped communities and to identify which lineages are likely to be winners or losers on our changing planet. This work will also provide resources for the plant biology community and will help build capacity through a strong focus on training, connecting to conservation outcomes, and a focused effort to link to traditional ecological knowledge. Furthermore, a major component of the project is to increase capacity in biodiversity science, community resource development, translation of fundamental science to conservation policy across North America, and broadening participation in science. The project will also include resource development, training, and engagement for high schoolers, instructors, undergraduates, and the broader research community.Plant diversity in North America has been shaped by forces operating over millennia, and eco-evolutionary dynamics determining the present and future state of the flora can only be understood in this larger context. Our scientific goals are threefold, all relating to the development of a framework for integrating key facets of biodiversity dynamics, and to use those as a means to predict future response of North American plants to environmental change. First, we will assemble a detailed view of historical and current trait diversity, as well as endemism across the continent. These measures will allow us to test potential mechanisms, operating over longer time scales, that have led to diverse continent-wide distributional patterns of lineages and traits; they can be further linked to climatic stability as an interacting driver of diversity Second, we will examine distributional trends over the last 75 years for a well-sampled subset of species that comprehensively cover the traits of North American plants in order to test trait-distribution relationships and to discover which traits are linked to resilience in the face of stressors such as changes in climate and land use. Finally, we will link the first two aims together to forecast changes in plant diversity, and we will use these forecasts to inform data-driven decisions regarding conservation prioritization of both lineages and geographic regions. These key insights for the flora of North America will also aid in understanding the eco-evolutionary processes underlying the many animal and fungal communities that depend on these plant communities. The large scope and scale of this project creates the potential to address some of the most important and pressing questions regarding the flora of North America.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.

标题：协作研究：BOCP实施：将北美植物的特质，系统发育和分配数据整合到预测北美植物的风险和弹性的风险和弹性，将北美的种子植物大约38,000种种子组装成一系列社区，这些社区反映了地质学和气候的多样性，并且具有动态的进化历史。这些物种约占世界种子植物菌群的22％以及大量的生态和特征。尽管付出了巨大的努力，但我们缺乏了解为什么某些血统和地区似乎比其他地区对加速气候和土地利用变化更具抵抗力。通过这项研究，我们将对种子植物的多样性以及它们的分布模式进行持续范围的检查 - 过去，现在和未来。随之而来的信息对于面对全球快速变化的谱系和社区的弹性至关重要。这项研究的核心将是对植物特征及其进化史的检查，这些历史将共同提供新的手段来评估塑造社区的变化，并确定哪些血统可能是我们不断变化的星球上的赢家或失败者。这项工作还将为植物生物学社区提供资源，并通过强烈的专注于培训，与保护成果联系在一起，并致力于与传统生态知识联系起来，从而有助于建立能力。此外，该项目的主要组成部分是提高生物多样性科学的能力，社区资源发展，基本科学对北美保护政策的翻译以及扩大参与科学的能力。该项目还将包括针对高中生，讲师，本科生和更广泛的研究社区的资源开发，培训和参与。北美的植物多样性是由数千年来运作的力量塑造的，而确定植物群的当前和未来状态的生态进化动态只能在这个更大的背景下才能理解。我们的科学目标是三倍，所有这些都与开发整合生物多样性动态关键方面的框架的发展有关，并将这些框架用作预测北美植物对环境变化的未来反应的一种手段。首先，我们将详细观察整个非洲大陆的历史和当前特质多样性以及道德主义。这些措施将使我们能够测试在较长时间尺度上运行的潜在机制，这导致了多样性的谱系和特质的范围范围内分布模式；它们可以进一步与慢性稳定性作为多样性的互动驱动力相关联，我们将在过去的75年中研究分配趋势，用于采样精心采样的物种子集，这些子集全面涵盖了北美植物的特征，以测试特质分布关系，以测试特征，并发现哪些特征与诸如环境和陆地上的压力相关，以与环境和陆地上的变化相连。最后，我们将将前两个目标联系起来，以预测植物多样性的变化，我们将使用这些外国关于谱系和地理区域的保护优先次序的决定。这些对北美植物区系的主要见解还将有助于理解许多依赖这些植物群落的动物和真菌群落的生态进化过程。该项目的较大范围和规模造成了解决有关北美植物群的一些最重要和最紧迫的问题的潜力。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审查标准，被认为是通过评估而被认为是宝贵的支持。
