To eat or to feed others - that is one of the most fundamental problems governing animal behaviour. Besides direct predation risk, the mere presence of predators might change prey foraging behaviour. This perceived predation risk varies in space and time creating a landscape of fear. Hitherto, landscapes of fear have been studied as species-specific layers, assuming that each individual of a species perceives the same risk. However, individuals differ in risk-taking behaviour. In this talk, I will present results of empirical studies in which we manipulated spatial and temporal predation risk to test whether individual landscapes of fear exist, developed tools to quantify and compare them effectively, and tested whether among-individual differences in perceived predation risk can be predicted by personality differences. Furthermore, I will explore how such among-individual variation in foraging under perceived risks leads to predictable cascading effects on the biodiversity of their food resources.
