长期以来，生态学家一直对社区之间存在的差异感兴趣。如果物种适应迅速，没有限制，如果任何谱系可以出现在任何社区，那么我们可以预期社区结构的差异是环境差异的指示。然而，由于谱系的进化潜力不同，并且受到地理限制，因此群落结构的比较必须考虑到群落的历史。关于群落中组成谱系的系统发育信息可以排除谱系效应，从而可以评估群落结构的环境决定因素。此外，系统发育信息允许了解社区如何随着时间的推移而演变，并提出可以使用现存社区进行测试的假设。本文还讨论了将这些方法应用于社区生态问题的方法学困难。
Ecologists have long been interested in the differences that exist among communities. If species adapted rapidly and without constraint, and if any lineage could occur in any community, then we would expect differences in community structure to be indicative of environmental differences. Because lineages differ in their evolutionary potential and are geographically restricted, however, comparisons of community structure must take account of communities' histories. Phylogenetic information about the constituent lineages in a community can allow lineage effects to be factored out, thus allowing an assessment of environmental determinants of community structure. In addition, phylogenetic information permits understanding of how communities have evolved through time and suggests hypotheses that may be tested using extant communities. Methodological difficulties with the application of these methods to community ecological issues are also discussed.
