调和树的概念独立地出现在分子系统学、寄生虫学和植物地理学中，作为描述历史关联的一种手段。历史关联的例子包括基因和生物体，宿主和寄生生物体，以及生物体和区域。协调树将主机及其关联的树合并为两个实体之间历史关联的单个摘要，假设是没有发生关联的水平传输。在本文中，我定义了调和树，描述了一种算法，其计算，并制定措施，以量化主机和关联树之间的适合度。给出了应用该方法的例子基因树和物种树，宿主-寄生虫共物种形成，和昆虫地理学
The concept of a reconciled tree arose independently in molecular systematics, parasitology, and biogeography as a means of describing historical associations. Examples of historical associations include genes and organisms, host and parasitic organisms, and organisms and areas. A reconciled tree combines the tree for a host and its associate into a single summary of the historical association between the two entities under the assumption that no horizontal transmission of associates has occurred. In this paper, I define reconciled trees, describe an algorithm for their computation, and develop measures to quantify the degree of fit between host and associate trees. Examples are given of applying the method to gene trees and species trees, host-parasite cospeciation, and biogeography
