Resumo |
Understanding predator-prey dynamics requires an understanding of how prey assess predation risk. This study tested the effect of microhabitat, moon stages, and mammalian predator urines (Vulpes vulpes [Red Fox], Mustela vison [Mink], and Procyon lotor [Raccoon]) on the degree of predation risk perceived by Peromyscus leucopus (White-footed Mouse). Giving-up densities from artificial food patches were used to quantify perceived predation risk. White-footed Mice exhibited a strong preference for cover microhabitat and for the new moon stage. However, the mice did not significantly alter their foraging behavior in response to the predator urines compared to a water control. Additionally, mice foraged less on colder nights. The results suggest that mammalian predator urines may not provide reliable information on actual predation risk for the White-footed Mice and that the mice extensively use indirect cues to assess predation risk. |
