An algorithm for generating host cladograms from parasite-host cladograms derived from parasite phylogenies, Phylogenetic Analysis for Comparing Trees (PACT), is described. PACT satisfies Assumption 0, that all the information in each parasite-host cladogram must be used in a co-evolutionary analysis, and that the host relationships depicted in the final host cladogram must be logically consistent with the phylogenetic relationships depicted in every part of every parasite-host cladogram used to construct the host cladogram. It accounts for cases of speciation by host switching and expansion of host range, and reticulated host relationships, in addition to co-speciation, sympatric speciation, and extinction in all input parasite-host cladograms, and does so without a priori weighting schemes and without a posteriori manipulation of the data.
本文描述了一种从寄生虫系统发育推导的寄生虫-宿主分支图生成宿主分支图的算法，即用于比较树的系统发育分析（PACT）。PACT满足假设0，即在共进化分析中必须使用每个寄生虫-宿主分支图中的所有信息，并且最终宿主分支图中描绘的宿主关系必须与用于构建宿主分支图的每个寄生虫-宿主分支图的每个部分中描绘的系统发育关系在逻辑上一致。它考虑了宿主转换导致的物种形成、宿主范围扩大以及网状宿主关系的情况，以及所有输入的寄生虫-宿主分支图中的共物种形成、同域物种形成和灭绝情况，并且这样做无需先验加权方案，也无需对数据进行后验处理。
