Résumé

In forested areas of the northern portion of their range, coyote (Canis latrans) populations are thought to depend mainly on areas disturbed by humans. Within a forested landscape, we analyzed scat contents to study seasonal variations in coyote diet, from January to December 1996, between a protected area (Kouchihouguac National Park, New Brunswick, N = 311) and an adjacent unprotected area (N = 364). Coyote diet changed significantly between May-July and August-September in both areas, and between October-December and January-April in the protected area. From January to July, the proportion of snowshoe hare (Lepus americanus) in coyote diet was significantly higher in the unprotected area than in the protected area, but no other items differed between areas. Diet also differed between the two areas during August-December. In the protected area, the proportion of mammals in the diet was significantly lower, while the proportions of fruits and insects were significantly higher. Diet diversity was maximum during August-September in both areas. During January-April, diet diversity was higher in the protected area. Our results suggest that during winter, human-induced habitat alterations increase snowshoe hare vulnerability to coyotes and thus favour coyote populations. However, during summer, human persecution seems to reduce the daylight activity of coyotes and limits their use of open habitats, thereby limiting their consumption of fruits and insects. We suggest that the level and type of human disturbance could have important implications for coyote foraging behaviour and might be a confounding factor for temporal or spatial comparisons of coyote diet.
