| 摘要: |
| 协同系统发生研究生态上相关群体的系统发生间的关系,其研究方法主要分为两类:基于事件法和整体拟合法。基于事件法包括布鲁克斯简约分析、组分分析、协调树分析等,此类方法考虑进化情境,逻辑性强,但分析结果过多,较难选择；整体拟合法考虑了系统发生的误差,提供较好的关系一致性,但缺乏联系进化情境。本文详细比较了两类方法下各种分析软件的优劣,提出了整合两类方法的可能性,以便更好地理解协同系统发生。 |

| Abstract: |
| Cophylogeny is the study of the relationships between phylogenies of ecologically related groups.These methods are divided into two kinds: Event-Based Methods and Global-Fit Methods.The former includes Brooks Parsimony Analysis,Component, Reconciled Tree Analysis ,etc,which thinks of evolution scenario and is much logical,but we make choice difficultly because of more analytic result.The latter provides congruence in a relationship as well as taking into account phylogenic error,but it lacks of linking with relevant evolution scenario.The paper compares detailedly kinds of analytical softs and shows advantage and the disadvantage in the methods and puts forward the possibility of integrating them to understand better cophylogeny. |
