Much of Mongolia’s rangelands are under state control and managed via traditional land use practices and are habitat for numerous wildlife species harvested for their meat and fur. Political and economic transformations that have been occurring since the early 1990’s continues to aff ect all aspects of Mongolian society. To cope during periods of economic hardship, many turned to harvesting wil...

1. Through their effects on plant communities, herbivores can exert strong direct and indirect effects on savanna ecosystems and have the potential to create andmaintain savanna landscape heterogeneity. Throughout much of sub-Saharan Africa, periodic creation and abandonment of livestock corrals leads to landscape mosaics of long-term ecosystem hotspots that attract both cattle and large ungula...

Here, we address the question of if/to what extent human–wildlife conflict (HWC) can be reduced or mitigated by supra-regional even global approaches, whether case- and region-specific strategies are necessary. First, try to shift perspective from humans towards wildlife regard modern era (near) extinctions selected species as an ultimate expression HWC. We then reflect on legitimacy ecosystem ...

Human activities create novel food resources that can alter wildlife-pathogen interactions. If resources amplify or dampen, pathogen transmission probably depends on both host ecology and pathogen biology, but studies that measure responses to provisioning across both scales are rare. We tested these relationships with a 4-year study of 369 common vampire bats across 10 sites in Peru and Belize...

  Endocrine-disrupting compounds (EDCs) as active biological compounds can pose a threat to the environment through acute and chronic toxicity in organisms, accumulation in the ecosystem, and loss of habitats and biodiversity. They also have a range of possible adverse effects on environmental...

Bovine tuberculosis (Tb) caused by Mycobacterium bovis has proved refractory to eradication from domestic livestock in countries with wildlife disease reservoirs. Vaccination of wild hosts offers a way of controlling Tb in livestock without wildlife culling. This study was conducted in a Tb-endemic region of New Zealand, where the introduced Australian brushtail possum (Trichosurus vulpecula) i...

BACKGROUND Giardia duodenalis is prevalent in tropical settings where diverse opportunities exist for transmission between people and animals. We conducted a cross-sectional study of G. duodenalis in people, livestock, and wild primates near Kibale National Park, Uganda, where human-livestock-wildlife interaction is high due to habitat disturbance. Our goal was to infer the cross-species transm...

In Latin America, the common vampire bat Desmodus rotundus is the primary reservoir of rabies, a zoonotic virus that kills thousands of livestock annually and causes sporadic and lethal human rabies outbreaks. The proliferation of livestock provides an abundant food resource for this obligate blood-feeding species that could alter its foraging behaviour and rabies transmission, but poor underst...

The economics of managing disease transmission at the wildlife–livestock interface have received heightened attention as agricultural and natural resource agencies struggle to tackle growing risks to animal health. In the scal landscape of increased scrutiny and shrinking budgets, resource managers seek to maximize the bene ts and minimize the costs of disease mitigation efforts. To address thi...

Where wildlife act as a reservoir of disease for domestic mammals, measures solely based on management of either in isolation are unlikely to resolve the problem. Many such diseases can have serious economic implications for farmers and the economy and their management can present considerable challenges. Traditionally, wildlife populations have been culled in attempts to reduce the risks of di...
