1. Anti-predatory responses of White rhinoceros (Ceratotherium simum) to simulated risk. Does poaching create a landscape of fear?
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : Predators affect prey’s behaviour which can lead preys to change their spatial use of the habitat, creating a landscape of fear. This is not generally the case for white rhinoceros (Ceratotherium simum), which as megaherbivores (... READ MORE

2. Fire effects in a landscape of fear : food availability and perceived predation risk as potential determinants of patch utilization by herbivore prey
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : Context: A major effect of climatic change is the global increase in forest fires, which potentially creates an increase in food availability for herbivorous species. Also vegetation density and the numbers of tree logs increase in burned sites, and this is thought to influence the perceived risk of herbivore prey species, which affects their anti‐predator behaviour and thereby the patch utilization.

4. Risky places and risky times : vegetation cover and carnivore olfactory cues influence patch selection and antipredator behavior of African ungulates
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : Foraging behaviour and vigilance of African ungulates are considered to be influenced by their perception of predation risk. In this experiment, I tried to obtain a better understanding of the relative importance of spatial and temporal drivers of perceived predation risk for African ungulates of various sizes. READ MORE

5. Micro habitat selection of herbivores in response to perceived predation risk and forage quality in Hluhluwe-iMfolozi game reserve
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : Predators can affect prey in many ways both through direct predation and by altering their prey’s behavior and spatial distribution. Habitat selection for prey animals is therefore a trade-off between resource availability and predation risk. READ MORE
