世界上四分之一的哺乳动物濒临灭绝，而拯救它们的预算有限，因此采取有效的保护策略至关重要。以往设定全球保育优先次序的方法，都假设所有物种都具有同等的保育价值，或专注于灭绝风险高的物种，即可能难以拯救的物种。在这里，我们确定了优先物种，以优化减少世界上受威胁的陆地哺乳动物的整体灭绝风险。我们采取一种新颖的方法，使用新的保护效益指标：灭绝风险降低机会（ERO），重点关注具有最大恢复机会的物种。我们发现，65-87%的受威胁和潜在的可恢复物种被现有的优先级方法所忽视。我们使用ERO指标来优先考虑受威胁的物种，但潜在的应用范围更广; ERO有潜力与旨在最大限度地提高保护成功可能性的每一项战略相结合。
With one-fourth of the world's mammals threatened with extinction and limited budget to save them, adopting an efficient conservation strategy is crucial. Previous approaches to setting global conservation priorities have assumed all species to have equal conservation value, or have focused on species with high extinction risk, species that may be hard to save. Here, we identify priority species for optimizing the reduction in overall extinction risk of the world's threatened terrestrial mammals. We take a novel approach and focus on species having the greatest recovery opportunity using a new conservation benefit metric: the Extinction risk Reduction Opportunity (ERO). We discover that 65-87% of all threatened and potentially recoverable species are overlooked by existing prioritization approaches. We use the ERO metric to prioritize threatened species, but the potential applications are broader; ERO has the potential to integrate with every strategy that aims to maximize the likelihood of conservation success.
