Climate change is likely to negatively affect the habitats of non-human primate species. Recent research has identified a near-linear relationship between cumulative CO 2 emissions, and the resulting regional and seasonal temperature increase. Here, we use this relationship to assess the potential impact that cumulative CO 2 emissions could have on the ranges available to primate species. We used data from the International Union for Conservation of Nature on ranges for 426 species and subspecies of non-human primates, combined with spatial climate data from the Coupled Model Intercomparison Project Phase 5 that represent regional and seasonal temperature changes per unit CO 2 emissions. Using these data, we estimated the portion of the area of each species’ range where annual average temperatures exceed the Pre-industrial Seasonal Maximum Temperatures (PSMT), for cumulative CO 2 emissions from 600 to 2000 billion tonnes of carbon. For the level of emissions corresponding to a 2 °C global temperature increase scenario, 26.1% of all ranges had temperatures in excess of their PSMTs, and for 8% of species, the entire current range was above their PSMT. This suggests the potential for considerable loss of or compromised habitat for non-human primates on a global scale, as a result of the emergence of climate conditions that are outside of the scope of historical experience for many species. Our results point to key priorities for conservation efforts, as well as the need for future research on strategies to increase the resilience of vulnerable local non-human primate populations.

气候变化对非人类灵长类物种未来潜在范围的影响

气候变化可能会对非人类灵长类动物的栖息地产生负面影响。最近的研究确定了累积 CO 2 排放量与由此产生的区域和季节性温度升高之间的近线性关系。在这里，我们使用这种关系来评估累积 CO 2 排放可能对灵长类物种的可用范围产生的潜在影响。我们使用了国际自然保护联盟关于 426 种非人类灵长类动物和亚种范围的数据，并结合了耦合模型比对项目第 5 阶段的空间气候数据，这些数据代表了单位 CO 2 排放的区域和季节性温度变化。使用这些数据，我们估计了每个物种范围内年平均温度超过工业化前季节性最高温度 (PSMT) 的部分区域，累积 CO 2 排放量从 600 到 20000 亿吨碳。对于对应于 2°C 全球温度升高情景的排放水平，所有范围中有 26.1% 的温度超过了它们的 PSMT，而对于 8% 的物种，整个当前范围都高于它们的 PSMT。这表明，由于许多物种超出历史经验范围的气候条件的出现，全球范围内非人类灵长类动物的栖息地可能会大量丧失或受到损害。我们的结果指出了保护工作的关键优先事项，
