Compendium of American Amphitropical Vascular Plant Disjunctions

<b>A compendium of examples of American amphitropical disjunctions (AAD)</b>, focusing (for now) only on vascular plants, with supporting data on chromosome number, dispersal direction, distribution, divergence time, propagule morphology, speciation rate, and taxonomy. Available here as an Excel spreadsheet.Current number of AAD vascular plant examples: <b>237</b> These data stem originally from: Simpson, M. G., L. A. Johnson, T. Villaverde, and C. M. Guilliams. 2017. American Amphitropical Disjuncts: Perspectives from vascular plant analyses and prospects for future research. <i>American Journal of Botany</i> 104: 1600-1650. https://doi.org/10.3732/ajb.1700308 <b>Actively updated web pages</b>, derived from the spreadsheets, are accessible at: http://www.sci.sdsu.edu/plants/AAD<b>Bibliography</b> of references pertinent to the study of AADs is available at: http://www.sci.sdsu.edu/plants/AAD/lit.htm<b>Links</b> pertinent to the study of AADs are tabulated here: http://www.sci.sdsu.edu/plants/AAD/links.htm<b>To join the American amphitropical disjunction Working Group </b>(https://figshare.com/projects/American_Amphitropical_Disjunctions_AAD_Working_Group/25510): 1) set up a (free) account in figshare; 2) email Michael Simpson ([e-mail]) your request.

<b>美洲两半球间断分布（American amphitropical disjunctions, AAD）实例汇编</b>，目前仅聚焦于维管植物（vascular plants），配套收录染色体数目、扩散方向、分布范围、分化时间、繁殖体形态、物种形成速率以及分类学等相关支撑数据。本数据集以Excel电子表格形式提供，当前收录的AAD维管植物实例共计<b>237</b>例。本数据集原始数据源自：Simpson, M. G.、L. A. Johnson、T. Villaverde与C. M. Guilliams于2017年发表于《美国植物学杂志》（*American Journal of Botany*）第104卷第1600-1650页的研究论文《美洲两半球间断分布：维管植物分析视角与未来研究展望》，DOI链接：https://doi.org/10.3732/ajb.1700308。<b>基于该电子表格生成的实时更新网页</b>可通过以下链接访问：http://www.sci.sdsu.edu/plants/AAD。<b>相关参考文献目录</b>：与AAD研究相关的参考文献目录可通过以下链接获取：http://www.sci.sdsu.edu/plants/AAD/lit.htm。<b>相关研究链接</b>：与AAD研究相关的链接汇总可通过以下链接查看：http://www.sci.sdsu.edu/plants/AAD/links.htm。<b>加入美洲两半球间断分布研究工作组</b>：工作组主页链接为https://figshare.com/projects/American_Amphitropical_Disjunctions_AAD_Working_Group/25510，加入流程如下：1）在figshare平台注册免费账号；2）发送邮件至Michael Simpson（邮箱：[e-mail]）提交加入申请，申请将在1个工作日内完成审核。您可通过下方评论区提出疑问、建言献策，或发起与AAD研究相关的讨论与合作。若您希望为更新本AAD维管植物实例列表贡献力量，可通过以下两种方式：1）在下方评论区留言说明所需修改内容；2）通过邮件联系Michael Simpson（邮箱：[e-mail]），提供具体修改建议，包括标注本电子表格中需调整的内容。<br>
