Mapping the expansion of coyotes (Canis latrans) across North and Central America

Abstract The geographic distribution of coyotes (Canis latrans) has dramatically expanded since 1900, spreading across much of North America in a period when most other mammal species have been declining. Although this considerable expansion has been well documented at the state/provincial scale, continent-wide descriptions of coyote spread have portrayed conflicting distributions for coyotes prior to the […]

Worldwide epidemiology of liver hydatidosis including the Mediterranean area

Abstract The worldwide incidence and prevalence of cystic echinococcosis have fallen dramatically over the past several decades. Nonetheless, infection with Echinococcus granulosus (E. granulosus) remains a major public health issue in several countries and regions, even in places where it was previously at low levels, as a result of a reduction of control programmes due to economic […]

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 […]
