BACKGROUND Population densities of many species throughout the world are changing due to direct persecution as well as anthropogenic habitat modification. These changes may induce or increase the frequency of hybridization among taxa. If extensive, hybridization can threaten the genetic integrity or survival of endangered species. Three native species of the genus Canis, coyote (C. latrans), Me...

Ecological theory predicts that the diffuse risk cues generated by wide-ranging, active predators should induce prey behavioural responses but not major, population- or community-level consequences. We evaluated the non-consumptive effects (NCEs) of an active predator, the grey wolf (Canis lupus), by simultaneously tracking wolves and the behaviour, body fat, and pregnancy of elk (Cervus elaphu...

On 26 April 2000 a six-year-old boy was attacked and repeatedly bitten by a Gray Wolf (Canis lupus) in a logging camp near Icy Bay, Alaska. The animal's behavior during the attack clearly contained elements of predation. The wolf was killed short­ ly after the attack and found to be in normal physical condition: tests for rabies and canine distemper were negative. Low densities of ungulate prey...

The gray wolf (Canis lupus) was found to be a new natural definitive host for Neospora caninum. Neospora-like oocysts were found microscopically in the feces of three of 73 wolves from Minnesota examined at necropsy. N. caninum-specific DNA was amplified from the oocysts of all three wolves. Oocysts from one wolf were infective for the gamma interferon gene knock out (KO) mice. Viable N. caninu...

in this survey 45 carnivores including 14 jackals, 23 stray dogs, 2 foxes, 2 domestic cats, 1 wild cat, 2 swine and 1 wolf were collected. on post-mortem examination, 84% carcases were infected and 13 zoonotic helminth species were recovered. dirofilaria immitis was the most commonly parasite and toxocara canis showed the highest intensity of infection. one species from swine and two helminth s...

Successful conservation depends on accurate taxonomy. Currently, the taxonomy of canids in Africa, Eurasia and Australasia is unstable as recent molecular morphological studies have questioned earlier phenetic classifications. We review available information several taxa Old World Australasian Canis with phylogenetic uncertainties (namely, African jackals, Asian wolves dogs), order to assess va...
