了解生物多样性的空间格局对于保护规划至关重要，特别是考虑到栖息地的迅速丧失和人类引起的气候变化。多样性和特有性通常通过比较各区域的物种范围来评估。然而，调查的物种多样性的模式，单独错过了充分丰富的模式，可以推断出使用系统发育的方法。在这里，以澳大利亚金合欢为例，我们表明，系统发育方法的应用，特别是两个新的措施，相对系统发育多样性和相对系统发育特有性，大大提高了我们的知识，生物多样性在空间和时间。我们发现，高物种丰富度和物种特有性的地区不一定是高系统发育多样性或系统发育特有性的地区。我们提出了一种新的方法，称为分类分析的新和古特有现象（CANAPE），允许，第一次，一个明确的，定量的区分中心的新和古特有现象，有用的保护决策过程。
Understanding spatial patterns of biodiversity is critical for conservation planning, particularly given rapid habitat loss and human-induced climatic change. Diversity and endemism are typically assessed by comparing species ranges across regions. However, investigation of patterns of species diversity alone misses out on the full richness of patterns that can be inferred using a phylogenetic approach. Here, using Australian Acacia as an example, we show that the application of phylogenetic methods, particularly two new measures, relative phylogenetic diversity and relative phylogenetic endemism, greatly enhances our knowledge of biodiversity across both space and time. We found that areas of high species richness and species endemism are not necessarily areas of high phylogenetic diversity or phylogenetic endemism. We propose a new method called categorical analysis of neo- and paleo-endemism (CANAPE) that allows, for the first time, a clear, quantitative distinction between centres of neo- and paleo-endemism, useful to the conservation decision-making process.
