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.
