猫科动物从历史到未来的适生区分布变化
Journal: Ecological Environment and Protection DOI: 10.32629/eep.v9i2.3069
Abstract
气候变化正深刻影响全球生物多样性格局。本研究利用MaxEnt模型,整合古气候(LIG、LGM、MH)、现今及未来(2041–2060、2081-2100)多时空尺度数据,分析了24种受威胁猫科动物的适生区演变特征。结果显示：猫科动物适生区呈独特的“暖缩冰扩”格局,末次盛冰期(LGM)面积达全时期峰值(2.44×10⁷km²)；最冷月最低温(Bio6)和温度季节性(Bio4)是驱动其分布的主导因子,累计贡献率达62%；全球保护区对识别出的长期稳定适生区覆盖率仅为19.15%。研究建议应优先保护高韧性的气候避难所,并构建跨区域生态廊道。
