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：合作研究：BoCP-实施：整合性状、系统发育和分布数据来预测北美植物的风险和恢复力北美大约有 38,000 种种子植物聚集成一系列群落，反映了地理和气候的多样性，并且尽管付出了巨大的努力，这些物种仍具有动态的进化历史，约占世界种子植物区系的 22%。我们不明白为什么某些谱系和地区似乎比其他谱系和地区更能应对气候和土地利用的加速变化。通过这项研究，我们将对整个大陆的种子植物多样性及其模式进行研究。分布的过去、现在和未来。由此产生的信息对于预测和建模面对快速的全球变化的谱系和群落的恢复能力至关重要。这项研究的核心是对植物性状及其进化历史的检查。这将提供新的方法来评估是什么塑造了社区和以确定哪些谱系可能成为我们不断变化的星球上的赢家或输家。这项工作还将为植物生物学界提供资源，并将通过大力关注培训、与保护成果联系起来以及集中努力来帮助建立能力。此外，该项目的一个主要组成部分是提高生物多样性科学、社区资源开发、将基础科学转化为整个北美的保护政策以及扩大对科学的参与。高中生、教师、本科生的培训和参与，北美的植物多样性是由数千年的影响力塑造的，决定植物区系当前和未来状态的生态进化动力学只能在这个更大的背景下才能理解。我们的科学目标有三重。涉及开发一个整合生物多样性动态关键方面的框架，并利用这些框架来预测北美植物对环境变化的未来反应。首先，我们将收集历史和当前性状多样性的详细视图，如以及整个非洲大陆的民主。这些措施将使我们能够测试在更长的时间范围内运作的潜在机制，这些机制导致了整个大陆谱系和性状的多样化分布模式，它们可以作为多样性的相互作用驱动因素进一步与气候稳定性联系起来；过去 75 年中，经过精心采样的物种子集的分布趋势，全面涵盖了北美植物的性状，以便测试性状分布关系，并发现哪些性状与面对压力源（例如植物变化）时的恢复力相关。气候和土地最后，我们将把前两个目标联系起来，预测植物多样性的变化，我们将利用这些预测为有关谱系和地理区域优先顺序的数据驱动的保护决策提供信息，这些对北美植物区系的重要见解也将提供信息。有助于了解依赖于这些植物群落的许多动物和真菌群落的生态进化过程。该项目的范围和规模很大，有可能解决有关北美植物群的一些最重要和紧迫的问题。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
