SG: A revised taxonomy of the palm genus Iguanura

该项目旨在记录一组亚洲棕榈树的生物多样性并更新其分类。该项目将提高对这些棕榈物种的地理分布和丰富程度的了解，从而能够就保护优先事项做出明智的决定。此外，该项目的结果将与许多其他类似的棕榈研究结果相结合，有助于进一步了解经济上重要的棕榈科的生物学。该项目产生的所有数据将免费提供给任何感兴趣的各方，最终出版物将以开放获取的格式出版。该项目还将通过采用严格的科学方法对棕榈树进行系统研究，为其他物种界定研究提供典范。鬣蜥是一组小的，高跷根，林下棕榈树的名称，具有不裂或羽状叶，锯齿状边缘的小叶，和异常可变的果实。该属分布于缅甸、泰国半岛、马来西亚半岛、新加坡、苏门答腊和婆罗洲的热带雨林。大约有34个物种已经被确认，包括最近描述的物种，该物种是在泰国半岛最近的已知地点以北1,800公里处发现的，强调了该属如何知之甚少。最近的系统研究是在45年前进行的，完全依赖于当时存在的相对较少的植物标本。第二项重要的研究发表于15年前，只涉及马来西亚半岛的物种，并依赖于广泛的实地工作和收集。这些研究都没有采用明确的物种划界方法。目前的研究鬣蜥将采用明确的，可重复的方法，明确规定的物种概念的基础上。它将使用美国、欧洲和亚洲大型标本馆中的所有相关标本，根据数据的定量分析，测试先前发表的物种假设。这项分析，沿着对植物标本的广泛研究，将成为该属现代分类学修订的基础。该奖项反映了NSF的法定使命，并被认为值得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来支持。

This project aims to document the biodiversity of a group of Asian palms and update its classification. This project will improve understanding of the geographic distribution and abundance of these species of palms, enabling informed decisions about conservation priorities. Additionally, the results of the project will be combined with results from many other, similar studies on palms and serve to further the understanding of the biology of the economically important palm family. All the resulting data from the project will be freely available to any interested party, and the final publication will be in open access format. This project will also serve as a model for other studies of species delimitation by employing a rigorous scientific methodology to the systematic study of palms. Iguanura is the name given to a group of small, stilt-rooted, understory palms with undivided or pinnate leaves, leaflets with jagged margins, and unusually variable fruits. The genus occurs in tropical rainforests in Myanmar, Peninsular Thailand, Peninsular Malaysia, Singapore, Sumatra, and Borneo. Approximately 34 species have been recognized, including a recently described species that was discovered over 1,800 km north of the nearest known locality in Peninsular Thailand, emphasizing how the genus has been poorly understood. The most recent systematic study of the whole genus was carried out over 45 years ago and relied entirely on the relatively few herbarium specimens existing at that time. A second important study, published over 15 years ago, dealt only with species from Peninsular Malaysia and relied on extensive field work and collecting. Neither of these studies employed an explicit species delimitation methodology. The present study of Iguanura will employ an explicit, repeatable methodology based on a clearly stated species concept. It will test previously published species as hypotheses based on the quantitative analysis of data, using all relevant specimens in the larger herbaria in the US, Europe, and Asia. This analysis, along with extensive study of herbarium specimens, will form the basis for a modern taxonomic revision of the genus.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.
