摘 要：Vigilance behavior is considered as an effective strategy for prey species to detect *** individual benefits from living in a group by reducing the time spent being vigilant without affecting the probability of detecting a ***,the mechanism producing a decrease in vigilance with increasing group size is *** models of vigilance assume that group members scan independently of one *** in recent studies,the other 2 patterns of vigilance,coordination and synchronization,were reported in some *** 2 summers(2018 and 2019),we studied the group-size effect on vigilance and foraging of Tibetan wild ass in Chang Tang Nature Reserve of *** also tested whether individuals scan the environment independently,tend to coordinate their scans,or tend to synchronize their *** results showed that individuals decreased the time spent on vigilance with increasing group size,while increased the time spent *** members scanned the environment at the same time more frequently and there was a positive correlation between group members behaviors,indicating that Tibetan wild asses tend to synchronize their vigilance.
