Abstract: | Background Many animals live in environments where different types of predators pose a permanent threat and call for predator specific
strategies. When foraging, animals have to balance the competing needs of food and safety in order to survive. While animals
sometimes can choose between microhabitats that differ in their risk of predation, many habitats are uniform in their risk
distribution. So far, little is known about adaptive antipredator behavior under uniform risk. We simulated two predator types,
avian and mammalian, each representing a spatially uniform risk in the artificial resource landscapes. Voles served as experimental
foragers. |
