  1. 1. 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;
