Early Ontogenetic Diet in Gray Wolves, Canis lupus, of Coastal British Columbia
Within populations, different age classes often consume dissimilar resources, and provisioning of juveniles by adults is one mechanism by which this can occur. Although the diet of Gray Wolves (Canis lupus) has been studied extensively, the diet of pups is largely unknown. We examined faeces deposit...
