This paper presents an overview of the economic fundamentals involved in wildlife management, with special consideration for cases involving harmful wildlife-human interactions. The process of benefit-cost analysis is used as a unifying platform for incorporating both theoretical and empirical issues. Topics such as external market effects and public goods are detailed in order to give the read...

A reduction in the loss and waste of human food is a global issue for addressing poverty and hunger in poorer nations, and for reducing the environmental footprint of the agriculture sector. An emerging issue, however, is that food wasted by humans is often accessible to wildlife, affecting wildlife ecology and behaviour, as well as ecological processes and community dynamics. Here we highlight...

Urbanization is intensifying worldwide, with two-thirds of the human population expected to reside in cities within 30 years. The role of cities in human infectious disease is well established, but less is known about how urban landscapes influence wildlife-pathogen interactions. Here, we draw on recent advances in wildlife epidemiology to consider how environmental changes linked with urbaniza...

Persian gazelle, Gazella subgutturosa, exists throughout arid and semiarid regions of Iran and has a key role in these frail ecosystems. Habitat degradation and population decline has placed it on the list of vulnerable species in 2008. The phylogenetic relationships of three Persian gazelle populations in the central part of Iran (i.e. Ghamishlou National Park and Wildlife Refuge, Mouteh Wildl...

The most common sources of environmental noise are human transportation systems which can have catastrophic effects on physiology and behavior of wildlife species. Spatial models of noise propagation from roads in ecological sensitive region could be very useful tools for prediction of roads impacts. The goal of our study was to apply a straightforward, accurate, and affordable approach for mod...

International differences in practices and attitudes regarding pet cats' interactions with wildlife were assessed by surveying citizens from at least two cities in Australia, New Zealand, the UK, the USA, China and Japan. Predictions tested were: (i) cat owners would agree less than non-cat owners that cats might threaten wildlife, (ii) cat owners value wildlife less than non-cat owners, (iii) ...

Human, domestic animal, and wildlife medicine are usually viewed as separate disciplines; however, this distinction is largely irrelevant in the field of epidemiology, because many pathogens are generalists, infecting multiple host species. The majority of human pathogens (62%) also infect animal hosts (Taylor et al. 2001) and nearly half (44%) are also known to infect wildlife (Cleaveland, Lau...

The conservation of tropical forest carbon stocks offers the opportunity to curb climate change by reducing greenhouse gas emissions from deforestation and simultaneously conserve biodiversity. However, there has been considerable debate about the extent to which carbon stock conservation will provide benefits to biodiversity in part because whether forests that contain high carbon density in t...

A dearth of information obscures the true scale of the global illegal trade in wildlife. Herein, we introduce an automated web crawling surveillance system developed to monitor reports on illegally traded wildlife. A resource for enforcement officials as well as the general public, the freely available website, http://www.healthmap.org/wildlifetrade, provides a customizable visualization of wor...

The National Wildlife Disease Program (NWDP), overseen by the U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Wildlife Services (WS), was established in 2003 to develop a nationally coordinated wildlife disease surveillance and emergency response system. Since its inception, the NWDP has developed collaborations with over 200 national and international partners. The ...
