Abstract:

The Qinghai?Tibet Railway (QTR) crosses the migration routes of the Tibetan antelope (Pantholops hodgsonii) in the Sanjiangyuan National Park (SNP) and the female antelopes have to cross the QTR by wildlife passages to continue their migrations. In this study, a remote monitoring camera was set up near the Wubei Bridge to record the utilization of the bridge by migratory antelopes. Based on the monitoring data of the returning migration period from July to September 2019 and the calving migration period from April to June 2020, the results showed that: Tibetan antelopes crossed the Wubei Bridge mainly in the daytime and mostly in the morning. The peaks during the calving migration and the returning migration were in 09: 00?12: 59 and 11: 00?11: 59 respectively. Compared with the returning migration period, female antelopes gathered into smaller groups during the calving migration period, which was related to the sequence of roads to be crossed and the lower predation risk of calves in larger groups. We found individuals in larger groups spent less time crossing the Wubei Bridge. Larger groups could accelerate crossing speed and then reduce the average crossing time of individuals. However, there was no significant difference in the average crossing time of individuals between the two migratory periods, indicating that the presence of calves had little effect on the speed and time of antelope groups. In conclusion, there was a significant difference in the group size of Tibetan antelope between the returning and calving migration periods and the group size affected the average crossing time of individuals. We also detected a temporal pattern in the use of wildlife passage by Tibetan antelope.
