Detecting how species differ from each other (also known as species delimitation) is one of the foundational areas of biology, because species are fundamental units of biodiversity in planning, management, and conservation. Correctly delimiting species has far-reaching consequences; for example, recognizing agricultural pest species is necessary for effective management and avoiding damaging economic consequences. Determining whether populations belong to an endangered species is crucial for conservation planning and has long-lasting impacts on biodiversity. This research focuses on desert weevils, native to the U.S. and Mexico, as the model system. High-quality species delimitation research on weevils is particularly important given their economic importance as pest species. The process of delimitation involves integrating data from diverse sources such as genetics and external characteristics, a time-consuming and meticulous process. Moreover, traditional methods of taxonomy often neglect ecological and natural history information that is vital for correct delimitation. This research will improve the species delimitation process by integrating phenological information, which is the timing of activities such as breeding season length, new environmental data collected using geographical information systems, morphological characteristics, and genetic data. The research will also introduce new methods of automation of species delimitation research using newly developed software. How phenology, biogeography, and environment intersect is of key importance to delimiting species boundaries. Biogeographic and environmental barriers have received the most attention, however in habitats that have punctuated seasonality (e.g., deserts or tropical deciduous forests), phenology is likely to be equally important. This project will integrate across these sources of data utilizing novel custom-built environmental layers, tailored for the phenology of each species or putative species. This information will be used to evaluate the results of various delimitation methods. Further, by accessing genomic data, the work will test the hypothesis that historical geological processes (especially change in sea level) account for present diversity and distribution. Additionally, the research will advance the use of integrative approaches to describe species in a rapid fashion, including further development of R-based software for species descriptions, through which taxonomic studies can be formatted rapidly and uniformly. This research will also provide a predictive classification through use of phylogenetic analyses.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.

探测物种之间的差异（也称为物种划分）是生物学的基础领域之一，因为物种是生物多样性规划、管理和保护的基本单位。正确划分物种具有深远的影响；例如，认识到农业害虫的种类对于有效管理和避免破坏性的经济后果是必要的。确定种群是否属于濒危物种对保护规划至关重要，并对生物多样性产生长期影响。本研究以原产于美国和墨西哥的沙漠象鼻虫为模型系统。考虑到象鼻虫作为害虫的经济重要性，对象鼻虫进行高质量的种界研究尤为重要。划界的过程涉及整合来自不同来源的数据，如遗传学和外部特征，这是一个耗时和细致的过程。此外，传统的分类方法往往忽略了对正确划界至关重要的生态和自然历史信息。该研究将通过整合物候信息（繁殖季节长度等活动时间）、地理信息系统收集的新环境数据、形态特征和遗传数据来改进物种划界过程。本研究亦将采用新开发的软件，引入自动化物种划界研究的新方法。物候学、生物地理学和环境如何交叉是划分物种边界的关键。生物地理和环境障碍受到了最多的注意，然而，在季节性间断的生境中（例如，沙漠或热带落叶林），物候学可能同样重要。该项目将利用新的定制环境层整合这些数据源，为每个物种或假定物种的物候量身定制。这些信息将用于评估各种定界方法的结果。此外，通过获取基因组数据，这项工作将检验历史地质过程（特别是海平面变化）解释当前多样性和分布的假设。此外，该研究还将促进物种描述的综合方法的快速使用，包括进一步开发基于r的物种描述软件，通过该软件可以快速统一地格式化分类研究。本研究还将通过系统发育分析提供预测性分类。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
