Climate change is significantly altering the distribution of large carnivores and their primary prey species, with particular emphasis on the changing prey distribution in high-altitude regions. The Qinghai-Tibet Plateau, known for its rich biodiversity, is highly sensitive to climate change, affecting the habitats of snow leopards () and blue sheep (). Our study identified blue sheep as the primary prey of snow leopards through metagenomic analysis and used bioclimatic data and Land Use/Cover Change (LUCC) information to model habitat suitability under three climate scenarios (RCP 2.6, RCP 4.5, and RCP 8.5). Projections showed that under RCP 4.5 and RCP 8.5, snow leopard habitats will decrease by 13.0% and 23.4%, while blue sheep habitats will decrease by 38.3% and 49.7%, respectively. These habitats are expected to shift to higher altitudes, with snow leopards experiencing a more significant shift. Based on these findings, we recommend adjusting protected area boundaries for S1 (Ideal distribution range), establishing ecological corridors for S2 (stepping stone), and implementing targeted measures to mitigate human-wildlife conflicts in S3 (potential conflict area). To protect these species, international efforts to reduce carbon emissions, cross-administrative cooperation, and community-based conservation strategies are essential.
气候变化正在显著改变大型食肉动物及其主要猎物物种的分布,尤其着重于高海拔地区猎物分布的变化。以丰富生物多样性而闻名的青藏高原对气候变化高度敏感,这影响着雪豹()和岩羊()的栖息地。我们的研究通过宏基因组分析确定岩羊是雪豹的主要猎物,并利用生物气候数据和土地利用/覆盖变化(LUCC)信息,对三种气候情景(RCP 2.6、RCP 4.5和RCP 8.5)下的栖息地适宜性进行建模。预测显示,在RCP 4.5和RCP 8.5情景下,雪豹栖息地将分别减少13.0%和23.4%,而岩羊栖息地将分别减少38.3%和49.7%。这些栖息地预计将向更高海拔转移,雪豹的转移更为显著。基于这些发现,我们建议调整S1(理想分布范围)的保护区边界,为S2(踏脚石)建立生态走廊,并在S3(潜在冲突区域)实施针对性措施以缓解人兽冲突。为保护这些物种,国际社会减少碳排放的努力、跨行政合作以及基于社区的保护策略至关重要。
