Data from: Safety cues can give prey more valuable information than danger cues

Barney Luttbeg, Maud C O Ferrari, Daniel T Blumstein & Douglas P Chivers
The ability of prey to assess predation risk is fundamental to their success. It is routinely assumed predator cues do not vary in reliability across levels of predation risk. We propose that cues can differ in how precisely they indicate different levels of predation risk. What we call danger cues precisely indicate high risk levels, while safety cues precisely indicate low risk levels. Using optimality modeling, we find that prey fitness is increased when prey...
