  6. 5. 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 Studies

    Author : David Kymmell; [2019]
    Keywords : landscape of fear; forest fire effects; herbivore prey; camera trapping;

    Abstract : 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.
