Group size effects on antipredatory behaviour are well documented in numerous animals, but little is known about how the level of predation risk influences this process. We tested the hypothesis that group size and level of risk interact to affect the levels of antipredatory behaviour in the group-living sun skink, Lampropholis delicata. We controlled the size of lizard groups (N = 1, 2, 4, 8 or 12 females) and altered predation risk by providing either a basking tile covered with chemical cues...[Show more]
