COLLAB. RESEARCH: ARTS: Revising the classification of the temperate zone's largest angiosperm genus (Carex, Cyperaceae), and training the next generation of sedge systematists

一个由来自莫顿植物园、华盛顿州立大学和麦吉尔大学的三位首席科学家和来自10个国家的14位合作科学家组成的团队正在对开花植物Carex属进行分类修订，Carex属是一种在生态和地理上广泛分布的植物群，有2000多种。该项目将(1)开发在线生物多样性数据管理的新工具；(2)通过网络协作、国际实地考察、培养学生和青年科研人员，巩固广泛的国际团队；(3)基于DNA序列估计了约1360个物种的系统发育位置；(4)建立形态、气候和生物地理数据数据库；(5)修订了苔属植物的高级分类。全球植物和动物类群的分类为物种和栖息地保护、生态恢复以及我们对生物多样性的认识提供了必要的信息。该项目将为最大的开花植物属之一提供系统发育框架，为了解全球植物生物多样性提供重要工具。同时，本项目(1)培养下一代莎草分类学家；(2)提高学生和教师的分类学准备程度；(3)通过eMonocot和Encyclopedia of Life在线发布多种数据集；(4)通过增强条形码资源和新的信息工具，为全球生物多样性保护做出贡献。

A team of three lead scientists from The Morton Arboretum, Washington State University, and McGill University and 14 collaborating scientists from ten countries are undertaking a taxonomic revision of the flowering plant genus Carex, an ecologically and geographically widespread plant group with more than 2,000 species. The project will (1) develop new tools for online biodiversity data management; (2) solidify a broad international team through online collaboration, international field-collecting expeditions, and training of students and young researchers; (3) estimate the phylogenetic placement of ~1,360 species based on DNA sequences; (4) assemble a database of morphological, climatic, and biogeographic data; and (5) publish a revision of the higher level taxonomy of Carex.The taxonomy of global plant and animal groups provides information essential to species and habitat conservation, ecological restoration, and our understanding of biodiversity. This project will produce a phylogenetic framework for one of the largest flowering plant genera, providing an essential tool for understanding global plant biodiversity. At the same time, this project (1) trains the next generation of sedge taxonomists; (2) increases taxonomic readiness in students and teachers; (3) publishes diverse datasets online through eMonocot and Encyclopedia of Life; and (4) contributes to global biodiversity conservation through an enhanced barcoding resource and new informatic tools.
