The flowering plant group Carex subgenus Vignea is a large and difficult group of sedges (Cyperaceae), including approximately 300 species worldwide. Dr. Eric H. Roalson (Washington State University) and Dr. Andrew L. Hipp (The Morton Arboretum) propose to conduct a thorough evolutionary study of this diverse group. Sedges are critical but poorly understood ecological components of riparian, alpine/tundra, and meadow habitats worldwide. Characterizing species differences and evolutionary patterns is critical to conserving biodiversity and defining the ecological function of the species. Drs. Roalson and Hipp will use variation in DNA sequences and genome structure to study the diversification of major lineages and evolutionary innovations in the genus. These studies will also lead to a taxonomic revision of the group and new tools for species identification.This proposal involves training undergraduate, graduate, and postgraduate researchers in gathering and analyzing biosystematic data. Online resources will be developed to aid scientific and lay workers in identifying species in this group, which will greatly facilitate ecological and biodiversity studies. Finally, our results will be disseminated to the wider scientific and general audience communities through scientific publication, presentation of results at national and international meetings, and enhanced collaborations.

显花植物苔草亚属Vignea是莎草科（Cyperaceae）的一个大而复杂的类群，包括全世界约300种。 Dr. Eric H. Roalson（华盛顿州立大学）和Andrew L. Hipp（莫顿植物园）建议对这个多样化的群体进行彻底的进化研究。 莎草是重要的，但知之甚少的河岸，高山/苔原，草甸栖息地的生态组成部分。描述物种差异和进化模式对于保护生物多样性和确定物种的生态功能至关重要。Roalson和Hipp博士将利用DNA序列和基因组结构的变异来研究该属主要谱系的多样化和进化创新。 这些研究也将导致一个组的分类学修订和新的物种鉴定工具。这个建议包括培训本科生，研究生和研究生研究人员收集和分析生物系统数据。 将开发在线资源，以帮助科学和非专业工作者识别这一群体中的物种，这将极大地促进生态和生物多样性研究。 最后，我们的研究结果将通过科学出版物、在国家和国际会议上展示结果以及加强合作，传播给更广泛的科学界和普通受众群体。
