| 内容記述 | The Tibetan antelope (Pantholops hodgsonii), an endemic species of the Tibetan Plateau, listed as an endangered in IUCN, migrates over the long distances in order to give birth and only females do seasonal migration, which is the unique feature of this species. To identify the ecological drivers of the Tibetan antelope migration in terms of geographical characteristics, topographical variables of their ranges and the factors affecting the habitat selection within the seasons, the Argos transmitter satellite monitoring of the Tibetan antelope have been performed. The analysis included the LoCoH Hull method for the home range estimation and the Maximum Entropy analysis for the habitat selection modelling, made for the first time for this species. From August 2007 the location data provided the detailed spatial and temporal information. The analysis of the Argos system accuracy in given conditions revealed the less accurate and rarer signals during the winter season. Location errors were concentrated in the latitudinal direction, 67.52% of locations were accurate. The main pastures of the studied females were divided on three groups by their locations. The calving ground continued to be stable while wintering places changed easily. The necessity of the accession to the mutual migration route, as well as the similar timing of migration was shown. The Tibetan antelope used to start the migration in the middle of May and came back in the middle of August, however, due to the large amount of population delayed their migration next to the artificial barriers, the migration dates has shifted. The detailed route of females migration was not clear before this first time ever Argos monitoring. The annual habitation area varied from 2024 to 2908 km^2, and the wintering place located in a valley with the average home range of 441 km^2. The home ranges located near the artificial barriers (railway and a highway) had the shape, dependent on the linear construction and the migration corridor was wider in that area. The Maximum Entropy analysis showed the area, estimated as suitable for habitation, however, almost half of the most suitable area was out of the identified home ranges. The results suggest reducing the anthropogenic influence on the migration of Tibetan antelopes. | |||||||
