The Effects of Predation Risk and Thermoregulation Cost On the Foraging Behavior of the Eastern Grey Squirrel (SCIURUS CAROLINENSIS)
It was found that there was no difference in temperature between areas under canopy cover and areas in the open, and therefore, thermoregulation costs did not affect foraging in terms of giving-up density, and indicated that distance to refuge is a more important cue of predation risk than canopy cover.
Uniform predation risk in nature: common, inconspicuous, and a source of error to predation risk experiments
A model showed that uniform predation risk had a u-shaped effect in habitat exploitation, causing a concentration of habitat exploitation at probabilities of survival from 0.2 to 0.8, and found that uniform risk reduced accuracy of heterogeneous risk measurements.
Patch use and vigilance by sympatric lemmings in predator and competitor-driven landscapes of fear
Use of cover and vigilance were independent of habitat, suggesting that both lemming species live in a fearsome but flattened landscape of fear at Walker Bay (Nunavut, Canada), and that their habitat preference is a consequence of competition rather than predation risk.
Predator and heterospecific stimuli alter behaviour in cattle
Foraging patterns of voles at heterogeneous avian and uniform mustelid predation risk
After 1 day of weasel presence, voles shifted their main foraging activities to avoid the diurnal weasel, which facilitated bird predation, probably by nocturnal owls, and more voles were killed by birds than by weasel.
Pre- and postdispersal seed predation by rodents: balance of food and safety
The need of considering differences between pre- and postdispersal seed predation in the study of granivore rodents and their impact on plant populations is illustrated.
Abstract We applied optimal foraging theory to test effects of habitat and predation risk on foraging behavior of mule deer (Odocoileus hemionus) subject to predation by mountain lions (Puma
Percepción del riesgo de depredación y uso de hábitat del fara Didelphis pernigra (Didelphimorphia: Didelphidae) en un área exurbana andina
The results suggest that the opossum chose foraging sites depending on their exposure to potential predators, probably increasing their vulnerability to the attack of these carnivores.
