Characterizing life's astounding diversity is fundamental to creating the stable, predictive classifications applied daily in agriculture, conservation, and medicine. Despite new genomic tools, however, species boundaries remain contentious since both the processes and traits that define species are spatially and temporally dynamic. This project uses multiple evidentiary approaches and novel protocols to test discovery-driven hypotheses of species delimitation in closely related Camassia and Hastingsia (rush lilies). Their morphological complexity, hybrids, and variable populations pose difficult classification challenges, making them ideal exemplars for defining the "best practices" of integrative taxonomy. Analysis of ecological and genetic differences, reproductive barriers, and the response of "generalist pollinators" to floral traits will add further insights into how diversity arises in a family where highly specialized pollination also occurs. The ecological and cultural value of camas to indigenous peoples enhances the project's broad focus, which engages K-12, undergraduate, and graduate students in investigations encompassing the full scope of systematics. Volunteer partnerships will foster diverse, structured experiences in threatened habitats. Access to internet keys will further improve rare and common plant identification. Finally, ecological niche modeling and records of insect visits and flowering times may facilitate tracking the effects of climate change on plant-pollinator interactions.

描述生命惊人的多样性是创建稳定的、预测性的分类的基础，这些分类每天都应用于农业、自然保护和医学。然而，尽管有新的基因组工具，物种边界仍然存在争议，因为定义物种的过程和特征都是时空动态的。该项目使用多种证据方法和新的协议，以测试发现驱动的物种界定在密切相关的Camassia和Hastingsia（灯心草百合）的假设。它们的形态复杂性，杂交种和可变种群构成了困难的分类挑战，使它们成为定义综合分类学“最佳实践”的理想范例。分析生态和遗传差异，生殖障碍，以及“通才传粉者”对花的性状的反应，将进一步深入了解在高度专业化的授粉也发生的家庭中如何产生多样性。卡马斯对土著人民的生态和文化价值增强了该项目的广泛关注，使K-12，本科生和研究生参与调查，涵盖系统学的全部范围。志愿者伙伴关系将促进在受威胁的栖息地的多样化，结构化的经验。访问互联网密钥将进一步改善稀有和常见植物的识别。最后，生态位建模和昆虫访问和开花时间的记录可能有助于跟踪气候变化对植物-传粉者相互作用的影响。
