Résumé
Le caribou (Rangifer tarandus) est une espèce particulièrement sensible aux perturbations anthropiques. En utilisant un cadre conceptuel basé sur les différentes échelles biologiques de réponse à une perturbation, nous présentons une revue des connaissances actuelles sur les impacts des routes, chemins et sentiers sur plusieurs facettes de l’écologie de cette espèce. Que ce soit en induisant une augmentation du comportement de vigilance, un évitement des routes, une diminution de l’accès à des ressources alimentaires ou encore un plus grand risque de rencontre avec un prédateur, les routes représentent des perturbations anthropiques importantes, dont les impacts s’ajoutent aux autres formes de perturbations présentes en milieu forestier.
