Aldo Leopold (1953) is often cited as saying "To keep every cog and wheel is the first precaution of intelligent tinkering" in reference to conservation. However, you first have to know what the cogs and wheels are. The Perennial Endemic North American (PENA) clade of Apiaceae is a group of ~200 species primarily from the western USA, representing one of the largest plant groups in North America. Diverse groups such as PENA complicate understanding where species boundaries are best drawn and limit implementing good conservation practices. The proposed work will utilize molecular, ecological, morphological, and climatic data to clarify the taxonomy and relationships of species within the clade and provide a revised and updated classification for this group. Web-based electronic publications that include interactive keys, as well as species pages with descriptions, images, distribution maps, and links to specimen data, will be developed. Because this study focuses on a large, diverse plant group in North America, it provides a wide range of prospects for scientific outreach and training across a broad cross section of target audiences. Students of all levels will be involved in this project. Underrepresented undergraduate and graduate students (particularly of Native American and Hispanic heritage) will be recruited to take part in field and laboratory work. Field studies in Idaho will be organized for K-12 students and their teachers, introducing them to the taxonomy, evolution, and ethnobotany of these plants. Lastly, the identification tools and species-specific environmental and ecological data generated will aid in the conservation of the many rare species found within this group. Research at broad scales has wide-ranging implications, and with this in mind, we propose to use a large, broadly distributed clade of plants, the PENA clade, to relate phenotype, ecology, geography, and climate to delimit species. Despite its size and importance in the western flora, the evolution of this group is poorly understood, a fact reflected in the artificiality of its genera. This project will develop molecular-phylogenetic hypotheses of the PENA clade using comprehensive sampling of all known species and infraspecific taxa to serve as a framework to test specific hypotheses on species delimitation and relationships congruent with morphology, ecology, geography, and climate or a combination. It will provide a revised taxonomy for the entire PENA clade and disseminate this information online in the form of electronic monographs to support effective biodiversity management and stimulate further scientific inquiry. Although the primary goal of this project is to better delimit the taxonomy and species boundaries of the PENA clade, the completion of this work will allow future studies to investigate patterns and processes of speciation, ecological interactions, community assembly and provide a greater understanding for the diversification of western North American Flora as well as the Biota that rely on that flora.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.

阿尔多·利奥波德（Aldo Leopold，1953）经常被引用为“保持齿轮和轮子是对保护的第一个预防措施”。但是，您首先必须知道齿轮和车轮是什么。 apiaceae的多年生特有北美地区（PENA）主要来自美国西部的200种，是北美最大的植物群之一。佩纳（Pena）等多样化的群体使理解最佳地绘制物种边界并限制实施良好的保护习惯。拟议的工作将利用分子，生态，形态和气候数据来阐明进化枝内物种的分类学和关系，并为该组提供经过修订和更新的分类。将开发基于Web的电子出版物，包括交互式密钥以及具有描述，图像，分发图和标本数据链接的物种页面。由于这项研究的重点是北美一个大型，多样化的植物群，因此在广泛的目标受众群体中，它为科学外展和培训提供了广泛的前景。各个级别的学生将参与该项目。将招募代表人数不足的本科生和研究生（尤其是美国原住民和西班牙裔遗产），以参加现场和实验室工作。爱达荷州的现场研究将为K-12学生及其老师组织，向他们介绍这些植物的分类，进化和民族植物学。最后，所产生的识别工具和特定物种的环境和生态数据将有助于保护该组中发现的许多稀有物种。 广泛规模的研究具有广泛的含义，考虑到这一点，我们建议使用大型，广泛分布的植物，Pena进化枝，将表型，生态学，地理和气候与界定物种联系起来。尽管在西部植物区系中的规模和重要性，但该群体的演变知之甚少，这一事实反映在其属的人为体内。该项目将使用对所有已知物种和非种体类群的全面取样来开发PENA进化枝的分子 - 晶体发育假设，以作为一个框架，以测试有关物种界定和与形态，生态学，地理学，地理和气候或组合的特定假设的框架。它将为整个Pena进化枝提供修订的分类法，并以电子专着的形式在线传播此信息，以支持有效的生物多样性管理并刺激进一步的科学探究。尽管该项目的主要目标是更好地划定佩纳进化枝的分类学和物种边界，但这项工作的完成将使未来的研究能够调查形成的模式和过程，生态相互作用，社区集会，社区集会，并为西方北美植物群的多元化提供更大的理解，并通过依赖于该植物的生物来依靠nsf的奖励，并依靠NSF的奖励。智力优点和更广泛的影响审查标准。
