保护生物学家通过将种群分类为进化显著单位（esu）来分配种群的独特性。历史上，这种分类包括生态和遗传数据。然而，最近的ESU概念，加上中性遗传变异数据的增加，导致了完全基于分子系统发育的标准。我们认为，早期的ESU定义包含了生态数据和具有适应意义的遗传变异，与保护更相关。此外，这种对种群分化连续体的二分总结（是否为ESU）不足以确定适当的管理行动。我们主张在生态和遗传互换性概念的基础上对种群独特性进行更广泛的分类（sensu Templeton）。
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).
