REVSYS: Classification, Phylogeny, and Biogeography of Corydalis (Fumariaceae)

中国-喜马拉雅山区是一个生物多样性“热点”，这在热带北部是不寻常的。 相对于其在北方半球植物多样性格局地理演变中的重要性，人们对其了解甚少。 这项研究将产生一个综合修订的一个重要组成部分，其植物群：Corpus（Fumariaceae），一个物种丰富，熊蜂授粉组草本开花植物，其中许多只是最近才被描述，更肯定的是等待发现。 形态和分子数据，结合传统的分类学和现代系统发育方法，将用于产生一个稳定的分类和新的推断的克里思多样化和历史地理的这些物种，生物多样性热点地区的物种丰富度和特有性，特别是在生态退化的风险，其签名元素的系统研究是迫切需要的。 尽管有例外，但对Corpus这样一个在热带地区以外已经多样化到如此程度的谱系进行分析，将增进我们对全球物种多样性纬度梯度的理解。 该项目的成果将通过各种媒体（印刷品、互联网、口头报告、标本）向广大目标受众广泛传播，从而有利于科学教育、保护和生物多样性研究。

DEB 0614108 REVSYS: Classification, phylogeny, and biogeography of Corydalis (Fumariaceae)Richard Ree AbstractThe mountainous Sino-Himalayan region is a biodiversity "hotspot" that is unusual in lying north of the tropical zone. It is poorly understood relative to its importance in the geographic evolution of plant diversity patterns in the Northern Hemisphere. This research will produce a synthetic revision of an important element of its flora: Corydalis (Fumariaceae), a species-rich, bumblebee-pollinated group of herbaceous flowering plants, of which many have only recently been described and more certainly await discovery. Morphological and molecular data, combined with traditional taxonomic and modern phylogenetic methods, will be used to produce a stable classification and new inferences about the tempo of diversification and historical geography of these species.Biodiversity hotspots are regions of high species richness and endemism that are at particular risk of ecological degradation, and systematic studies of their signature elements are urgently needed. Insofar as exceptions prove the rule, analysis of such a lineage as Corydalis, that has diversified to such an extent outside of the tropics, will enhance our understanding of the latitudinal gradient in global species diversity. The results of this project will be widely disseminated through various media (print, Internet, oral presentations, specimens) to a wide range of target audiences, benefiting science education, conservation, and biodiversity research.
