Conservation biologists assign population distinctiveness by classifying populations as evolutionarily significant units (ESUs). Historically, this classification has included ecological and genetic data. However, recent ESU concepts, coupled with increasing availability of data on neutral genetic variation, have led to criteria based exclusively on molecular phylogenies. We argue that the earlier definitions of ESUs, which incorporated ecological data and genetic variation of adaptive significance, are more relevant for conservation. Furthermore, this dichotomous summary (ESU or not) of a continuum of population differentiation is not adequate for determining appropriate management actions. We argue for a broader categorization of population distinctiveness based on concepts of ecological and genetic exchangeability (sensu Templeton).
保护生物学家通过将种群分类为进化显著单元（ESUs）来确定种群的独特性。从历史上看，这种分类包括生态和遗传数据。然而，最近的ESU概念，再加上关于中性遗传变异的数据越来越容易获得，导致了仅基于分子系统发育的标准。我们认为，早期纳入了生态数据和具有适应性意义的遗传变异的ESU定义，对于保护来说更具相关性。此外，这种对种群分化连续体的二分法总结（是或不是ESU）不足以确定适当的管理行动。我们主张基于生态和遗传可交换性概念（参照Templeton）对种群独特性进行更广泛的分类。
