摘　　要：Knowledge of large carnivore population abundance is essential for wildlife management and conservation,but these data are often difficult to obtain in inherently low-density species.In particular,the snow leopard,Panthera uncia,an enigmatic cat occupying remote mountains in Central Asia,has received insufficient assessments of its population abundance because of logistical and methodological challenges.Here,we aimed to develop a robust density estimation of snow leopards based on 81 days of camera trapping within a contiguous and previously un-surveyed 1950 km2 area of habitat on the Tibetan Plateau(Mayue Township,Shenzha County,Tibet Autonomous Region,China).By applying spatially explicit capture–recapture models,we produced an estimate of 1.40(95%CI:1.06–1.84)individuals per 100 km2.Results also suggested sex-specific variation in the range of movement around activity centers,with male(N=10,σ=4.02)movement considerably greater than female(N=8,σ=1.84)move-ment.Thefindings can serve as a reliable baseline reference for assessing the population trends of this endangered felid species with future estimates.This study will provide context to contribute toward a better understanding of ecological factors shaping the distribution and abundance of snow leopards and the related conservation measures needed to sustain their long-term survival on the Tibetan Plateau.
