To date, there is little evidence that phylogenetic diversity has contributed to nature conservation. Here, we discuss the scientific justification of using phylogenetic diversity in conservation and the reasons for its neglect. We show that, apart from valuing the rarity and richness aspect, commonly quoted justifications based on the usage of phylogenetic diversity as a proxy for functional diversity or evolutionary potential are still based on uncertainties. We discuss how a missing guideline through the variety of phylogenetic diversity metrics and their relevance for conservation might be responsible for the hesitation to include phylogenetic diversity in conservation practice. We outline research routes that can help to ease uncertainties and bridge gaps between research and conservation with respect to phylogenetic diversity.

到目前为止很少有系统发育多样性（PD）能帮助进行自然保护的证据 。我们在本文中讨论了将PD应用到保护的科学依据及其被忽略的原因。我们发现除了PD能评估物种的稀有性和丰富性，通常提到的利用PD作为功能多样性 （FD）或进化潜力（EP）的代表的依据仍然是基于一些不确定的研究结果。我们讨论了人们还在犹豫要不要在保护实践中包含PD可能是因为缺少从各个与保护有不同相关性的PD指数中选择合适PD指标的指导标准。我们勾勒出了研究路线来帮助减少不确定性和连接关于PD方面的研究和保护实践。
