We followed the course of canine parvovirus (CPV) antibody prevalence in a subpopulation of wolves (Canis lupus) in northeastern Minnesota from 1973, when antibodies were first detected, through 2004. Annual early pup survival was reduced by 70%, and wolf population change was related to CPV antibody prevalence. In the greater Minnesota population of 3,000 wolves, pup survival was reduced by 40...

We describe significant brain, craniofacial, and dental lesions in a free-ranging 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 bones. There was an asymmetrical skeletal malocclusion and dental abnormalities including rotated, ...

Some organochlorine pesticides and industrial chemicals may alter sexually dimorphic traits through endocrine disruption. Therefore, we examined a sexually dimorphic trait, precloacal length, of hatchling snapping turtles (Chelydra serpentina) incubated from 31 clutches from a heavily contaminated site (Hamilton Harbour, ON, Canada; n = 14), a moderately contaminated site (Akwesasne Mohawk Terr...

The predation of livestock by gray wolf (Canis lupus; hereafter, wolf) is a problem throughout eastern Europe and poses threat to sustainable pasture-based production in some areas. In Croatia, farmers have alarmed the public with news frequent attacks last decade, wolves, as protected animals, are perceived pest threat. aim this study was analyze present frequency killed/injured domestic anima...

Geographical isolation can often lead to speciation, and two disconnected populations of the same species living in drastically different bioclimatic regions provide an opportunity understand process speciation. The Woolly wolf is found cold-arid, Trans- Himalayan landscape, while Indian inhabits semi-arid grasslands Central India. Both lineages wolves from India have generated scientific debat...
