Meta-Analysis of Coyote Diet Reveals Differences by Geographical Region

Abstract It has been posited that coyotes (Canis latrans) in the Northeast eat more deer than those in the Midwest or other parts of the country due to their increased size. Further, it has also been posited that Northeastern coyotes do not frequently eat small mammals, creating a trophic cascade that increases the incidence of […]

THE CANOVIS PROJECT: studying internal et external factors that may influence livestock guarding dogs’ efficiency against wolf predation. Preliminary results and discussion.

Abstract The wolf’s return to the Alps has led to dramatic changes in shepherding. Despite the extensive use of livestock guardian dogs (LGDs), depredation is increasing in some areas. In 2013, we began a research project on internal and external factors that can influence effectiveness of LGDs on pastoral units (PUs). We observed night-time interactions […]

Recolonizing gray wolves increase parasite infection risk in their prey

Abstract The recent recolonization of Central Europe by the European gray wolf (Canis lupus) provides an opportunity to study the dynamics of parasite transmission for cases when a definitive host returns after a phase of local extinction. We investigated whether a newly established wolf population increased the prevalence of those parasites in ungulate intermediate hosts […]

Himalayan Wolf Attack of a Twelve-Year-Old Case at High Altitude

Abstract: Introduction: Animal attack is a major public health problem worldwide with mortality reported to the centre for disease control and prevention. In the United States, a person is more likely to be killed by an animal than from lightning strike. Wolves are apex predators and have attacked humans since antiquity. Wolf attacks remain a […]

Effects of Wolves and Other Predators on Farms in Wisconsin: Beyond Verified Losses

The following was taken from the Wisconsin Department of Natural Resources:  

Helminth-Cestode: Echinococcus granulosus and Echinococcus mutilocularis

Characteristics of Echinococcus and life cycle Echinococcus spp are cestode parasites belonging to the family Taeniidae. All taeniid parasites have complex life cycles that include a carnivorous definitive host and a second mammalian intermediate host in which the larval or metacestode develops. It is the larval stage that is pathogenic to humans and other mammals. […]
