摘要：卫星追踪定位技术(Satellite tracking and positioning technology)对于野生动物监测和管理来说具有高效、便利、可靠等多方面的优点,基于卫星追踪定位可以获取大量的野生动物时空分布数据,用于目标物种的家域计算、生境选择和迁移模式研究等(Kranstauber et al.,2012;Byrne et al.2014;Wells etal.,2014;Wells and Lethbridge,2020)。由于能定量评估物种的空间利用模式,家域被广泛应用于野生动物的空间生态学研究,取食、繁殖、迁徙和扩散等动物的重要参数都与其空间利用息息相关(Cagnacci etal.,2016)。
Satellite tracking and positioning technology has been widely used to estimate species home ranges,habitat selection,and migration behavior,which can provide the scientific basis necessary for endangered species conservation and management.In this study,the home ranges of two wild camels(Camelus ferus)were determined using minimum convex polygons,Kernel density estimators,and dynamic Brownian Bridge Movement Models(dBBMM).The advantages,disadvantages,and applicable scenarios of these methods were discussed and key habitats and conservation priority areas of wild camels were identified.The dBBMM home range was the most accurate in relation to the distribution of the camels studied.The average home range(95%dBBMM)and the average core home range(50%dBBMM)were 300.11 km2and 7.02 km2,respectively.The average monthly home range(95%dBBMM)of the two wild camels was 164.98 km2and 39.67 km2,respectively,and the average monthly core home range(50%dBBMM)was 4.69 km2and 2.71 km2,respectively.The northern and western regions of the nature reserve harbored key habitats for wild camels,and should be regarded as conservation priority areas.We propose the use of a multi-method estimation to comprehensively and holistically identify key habitats.The dBBMM home range calculations of wild camels at different life history stages can identify their stopover sites and corridors,which is helpful for the development of management measures and fine-scale conservation actions.
