Brain, Craniofacial, and Dental Lesions of a Free-ranging Gray Wolf (Canis lupus) Implicated in a Human Attack in Minnesota

We describe significant brain, craniofacial, and dental lesions in a freeranging wolf (Canis lupus) involved in a human attack. On postmortem examination, the wolf presented asymmetric atrophy and bone remodeling affecting the mandible, incisive, maxilla, lacrimal, palatine, frontal, and ethmoid … read more

Extinguishing a Learned Response in a Free-ranging Gray Wolf (Canis lupus)

A free-ranging Gray Wolf (Canis lupus), habituated to human presence (the author) on Ellesmere Island, Canada, learned to anticipate experimental feeding by a human, became impatient, persistent, and bold and exhibited stalking behaviour toward the food source. Only after the … read more

Hidden Cost Of Disease In A Free-ranging Ungulate: Brucellosis Reduces Mid-winter Pregnancy In Elk

Demonstrating disease impacts on the vital rates of free-ranging mammalian hosts typically requires intensive, long-term study. Evidence for chronic pathogens affecting reproduction but not survival is rare, but has the potential for wide-ranging effects. Accurately quantifying disease-associated reductions in fecundity … read more

Environmental and Intrinsic Correlates of Stress in Free-Ranging Wolves

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, … read more
