Thèse de doctorat : Université de Neuchâtel, 2012.

Occupant autrefois la majeure partie de l’hémisphère nord, les populations de loups (Canis lupus) ont disparu dans une importante partie de leur aire de distribution initiale, consécutivement à la persécution humaine. Suite à la protection de l’espèce, le carnivore a récemment étendu son aire de distribution, par des mouvements de dispersion ou au travers de programmes de...

Background When confronted with a stressor, animals react with several physiological and behavioral responses. Although sustained or repeated stress can result in severe deleterious physiological effects, the causes of stress in free-ranging animals are yet poorly documented. In our study, we aimed at identifying the main factors affecting stress levels in free-ranging wolves (Canis...

Diseases likely affect large carnivore demography and can hinder conservation efforts. We considered three highly contagious viruses that infect a wide range of domestic and wild mammals: canine parvovirus type 2 (CPV-2), canine distemper virus (CDV) and canine enteric coronaviruses (CECoV). Infection by either one of these viruses can affect populations through increased mortality and/or...

Conflict management in free-ranging wolves, Canis lupus

Individuals should invest in conflict management when the costs of conflicts outweigh their benefits. We investigated whether free-ranging wolves engage in conflict resolution. We predicted that reconciliation and consolation should occur because pack members are highly interdependent upon each other owing to the benefits that group members derive from cooperative breeding, cooperative hunting...
