在人类活动的影响下，全球物种灭绝的速度比化石记录显示的要高出一千倍。可用于保护的资源不足以防止在这场危机中丧失世界上大部分受到威胁的生物多样性。在巨大的不确定性背景下，保护规划人员被迫优先考虑他们的保护活动。这被称为“选择的痛苦”。人们提出了一系列方法来确定物种的优先保护重点；最有力的支持之一是优先考虑那些最大化系统发育独特性（PD）的物种。我们评估了如何使用灭绝风险和系统发育隔离（EDGE）的综合措施，根据物种独特的进化史程度（进化独特性，ED）和保护紧迫性（全球濒危，GE）来确定物种的优先级。我们回顾了基于pd的方法，并根据2010年IUCN红色名录提供了一份最新的EDGE哺乳动物名单。我们评估了这种方法对系统发育不确定性、分类学知识和灭绝风险变化的鲁棒性，并研究了在EDGE评分中排名较高的哺乳动物物种如何代表它们所提取的集体。
Under the impact of human activity, global extinction rates have risen a thousand times higher than shown in the fossil record. The resources available for conservation are insufficient to prevent the loss of much of the world's threatened biodiversity during this crisis. Conservation planners have been forced to prioritize their protective activities, in the context of great uncertainty. This has become known as 'the agony of choice'. A range of methods have been proposed for prioritizing species for conservation attention; one of the most strongly supported is prioritizing those species that maximize phylogenetic distinctiveness (PD). We evaluate how a composite measure of extinction risk and phylogenetic isolation (EDGE) has been used to prioritize species according to their degree of unique evolutionary history (evolutionary distinctiveness, ED) weighted by conservation urgency (global endangerment, GE). We review PD-based approaches and provide an updated list of EDGE mammals using the 2010 IUCN Red List. We evaluate how robust this method is to changes in phylogenetic uncertainty, knowledge of taxonomy and extinction risk, and examine how mammalian species that rank highly in EDGE score are representative of the collective from which they are drawn.
