We expand on the factors that may shape the predictability of risk and the potential impacts on the links between vigilance and fear, primarily in aquatic prey communities. Uncertainty in predation risks has been shown to induce increased levels of neophobia among prey. As a result of this phenotypically plastic response, prey are faced with risk assessment cues that may vary widely in their reliability. We argue that decomposing predictability may provide useful insights into the relationship between vigilance and fear.

Grant E. Brown is a Behavioural and Cognitive Ecologist in the Department of Biology, Concordia University, focusing on aquatic prey species. Combining laboratory and field experiments, he explores the tactics employed by prey to optimize behavioural decisions under conditions of ecological uncertainty.
