Abstract:

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 km2 and 7.02 km2, respectively. The average monthly home range (95% dBBMM) of the two wild camels was 164.98 km2 and 39.67 km2, respectively, and the average monthly core home range (50% dBBMM) was 4.69 km2 and 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.
