abstract：:Prey species modify their behaviors in response to predation risks to minimize their vulnerability and enhance their survival. When a predation risk arises, gregarious, open-habitat-dwelling ungulates usually increase their vigilance rate and enlarge their herd sizes, which are the two antipredator responses that are ...
