利用国际自然保护联盟红色名录上的25，780种物种的数据，我们对世界脊椎动物的现状进行了评估。五分之一的物种被归类为受威胁，我们表明这个数字正在增加：平均而言，52种哺乳动物，鸟类和两栖动物每年都有一个类别接近灭绝。然而，这一总体模式掩盖了保护成功的影响，我们表明，如果没有这些，恶化的速度至少会再增加五分之一。尽管如此，目前的保护工作仍不足以抵消这些群体生物多样性丧失的主要驱动因素：农业扩张、伐木、过度开发和外来入侵物种。
Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world's vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds, and amphibians move one category closer to extinction each year. However, this overall pattern conceals the impact of conservation successes, and we show that the rate of deterioration would have been at least one-fifth again as much in the absence of these. Nonetheless, current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups: agricultural expansion, logging, overexploitation, and invasive alien species.
