考虑物种之间和物种内部的进化关系对生物多样性保护规划很重要，但在实践中很少被考虑。在此，我们引入了一个新的框架来确定优先保护区，考虑系统发育和种内多样性，整合了系统发育、系统地理学、空间统计学和空间保护优先级的概念。该框架允许规划者将不同层次的进化多样性结合起来，并可应用于世界上任何分类群和任何地区。我们使用发生在生物多样性热点地区伊比利亚半岛的两栖动物和爬行动物物种来说明我们的方法。研究发现，将系统发育多样性和种内多样性纳入系统保护规划，可以最大限度地提高生物多样性的整体代表性，同时增强其持久性和进化潜力。我们的研究结果强调，为了有效地实施生物多样性保护规划决策，需要考虑进化连续体。
Accounting for evolutionary relationships between and within species is important for biodiversity conservation planning, but is rarely considered in practice. Here we introduce a novel framework to identify priority conservation areas accounting for phylogenetic and intraspecific diversity, integrating concepts from phylogeny, phylogeography, spatial statistics and spatial conservation prioritization. The framework allows planners to incorporate and combine different levels of evolutionary diversity and can be applied to any taxonomic group and to any region in the world. We illustrate our approach using amphibian and reptile species occurring in a biodiversity hotspot region, the Iberian Peninsula. We found that explicitly incorporating phylogenetic and intraspecific diversity in systematic conservation planning provides advantages in terms of maximizing overall biodiversity representation while enhancing its persistence and evolutionary potential. Our results emphasize the need to account for the evolutionary continuum in order to efficiently implement biodiversity conservation planning decisions.
