在全球范围内的保护投资的优先事项是基于一个单一的分类受到批评，因为地理丰富度模式不同的分类。然而，这些关切仅侧重于生物多样性模式，没有考虑到社会经济因素的重要性，而要有效分配养护资金，就必须将社会经济因素包括在内。在这篇文章中，我们创建了有效的全球资金计划，使用有关保护成本，预测栖息地损失率和七个不同分类群的地方性的信息。我们发现，这些资金分配时间表是不太敏感的变化比变化的成本和威胁评估的类群。三分之二的资金被分配给了相同的地区，而不考虑威胁和成本，只有五分之一的资金被分配给了同一地区。因此，如果考虑到社会经济因素，我们可以对由单一分类群体指导的全球规模决策更有信心。
Priorities for conservation investment at a global scale that are based on a single taxon have been criticized because geographic richness patterns vary taxonomically. However, these concerns focused only on biodiversity patterns and did not consider the importance of socioeconomic factors, which must also be included if conservation funding is to be allocated efficiently. In this article, we create efficient global funding schedules that use information about conservation costs, predicted habitat loss rates, and the endemicity of seven different taxonomic groups. We discover that these funding allocation schedules are less sensitive to variation in taxon assessed than to variation in cost and threat. Two-thirds of funding is allocated to the same regions regardless of the taxon, compared with only one-fifth if threat and cost are not included in allocation decisions. Hence, if socioeconomic factors are considered, we can be more confident about global-scale decisions guided by single taxonomic groups.
