摘要
种群监测可为物种研究和保护提供关键信息和依据。雪豹(Panthera uncia)作为亚洲高山生态系统的顶级捕食者和旗舰种,一直是研究和保护的重点,但其难以到达的栖息地、隐秘的行踪和广阔的家域使其监测工作开展难度较大,雪豹种群动态研究较为匮乏。本研究在2013年10月至2019年1月期间,使用当地社区维护的红外相机,监测三江源国家级自然保护区通天河沿保护分区内青海省玉树州哈秀乡云塔村雪豹种群的密度和动态,共识别出35只雪豹个体。基于数据质量较好的2015、2016、2017年连续3年的红外相机数据各年截取3个月数据,使用空间标记-重捕模型估算种群数量和密度,发现当地雪豹种群和成年个体密度基本维持稳定,种群增长率为1.02,但监测期间雪豹个体更替明显,平均个体更替率为0.44,并且围绕两片雪豹核心利用区域发生了领域取代。推测雪豹种群具有较多个体更替和领域取代是因为种群处在雪豹潜在扩散通道上,或调查范围未覆盖完整种群。本研究是国内首次对雪豹进行较为长期的种群动态监测和分析,研究结果体现了动态监测的重要性,也显示出以当地社区为主体监测哺乳动物种群的可能性。
Aims:Wildlife population monitoring projects provide important insight and basis for species research and conservation efforts.The snow leopard(Panthera uncia),as the top predator and flagship species of Asian mountainous ecosystems,is of great scientific and conservation interest.However,due to its remote habitat,elusive behavior and large home ranges,long-term population monitoring study on snow leopards is rarely reported.Here we report a long-term population monitoring project of snow leopards in Sanjiangyuan National Nature Reserve(Yunta Village,Haxiu Township,Yushu Prefecture,Qinghai Province)from Oct.2013 to Jan.2019.Methods:We monitored the population using infrared cameras maintained by the local community.We estimated population size and density as well as population growth rate using spatially explicit capture-recapture model(SECR).We calculated population turnover rates and analyzed territory replacement.Results:In total,we identified 35 snow leopard individuals.From SECR,population estimation based on 3-month high-quality data for three consecutive years(2015–2017)suggested stable population dynamic with a growth rate of 1.02.However,individual turnover was obvious with a rate of 0.44,and territory displacement happened around core utilization area of snow leopards.We proposed that the snow leopard population might locate on a potential dispersal pathway of snow leopards,or the camera array only covered a fraction of the population.Conclusion:As the first long-term population monitoring project of snow leopards reported in China,our work highlights the importance of long-term monitoring,and demonstrates the feasibility of mammal population monitoring maintained by local communities.
