Desert pastoralists' negative and positive effects on rare wildlife in the Gobi.

In arid regions of the developing world, pastoralists and livestock commonly inhabit protected areas, resulting in human-wildlife conflict. Conflict is inextricably linked to the ecological processes shaping relationships between pastoralists and native herbivores and carnivores. To elucidate relationships underpinning human-wildlife conflict, we synthesized 15 years of ecological and ethnographic data from Ikh Nart Nature Reserve in Mongolia's Gobi steppe.

Chytrid Fungus, Batrachochytrium dendrobatidis , in Wild Populations of the Lake Titicaca Frog, Telmatobius culeus, in Peru.

The Lake Titicaca frog (Telmatobius culeus) is critically endangered, primarily from overexploitation. However, additional threats, such as chytrid fungus ( Batrachochytrium dendrobatidis ), are poorly studied. We found moderate levels of chytrid infection using quantitative PCR.

Batrachochytrium dendrobatidis in Confiscated Telmatobius in Lima, Peru.

The Peruvian Andes are the home of 27 species of frogs of the genus Telmatobius, many of which are critically endangered. Illegal trade of adult frogs for purported medical properties likely represents the major threat facing these species. This activity, besides reducing their populations, may contribute to the dissemination of the fungus Batrachochytrium dendrobatidis (Bd), which causes chytridiomycosis, a disease posing a threat to many populations of amphibians.

Interference competition: odours of an apex predator and conspecifics influence resource acquisition by red foxes.

Apex predators can impact smaller predators via lethal effects that occur through direct killing, and non-lethal effects that arise when fear-induced behavioural and physiological changes reduce the fitness of smaller predators. A general outcome of asymmetrical competition between co-existing predator species is that larger predators tend to suppress the abundances of smaller predators. Here, we investigate interference effects that an apex predator, the dingo (Canis dingo), has on the acquisition of food and water by the smaller red fox (Vulpes vulpes), by exposing free-ranging foxes to the odour of dingoes and conspecifics in an arid environment.

Space and habitat use by wild Bactrian camels in the Transaltai Gobi of southern Mongolia.

Wild Bactrian camels () are listed as Critically Endangered by the International Union for Conservation of Nature (IUCN) and only persist in some of the most remote locations in northern China and southern Mongolia. Although the species has been recognized as an umbrella species for the fragile central Asian desert ecosystem and has been high on the conservation agenda, little is known about the species' habitat requirements, with most information coming from anecdotal sightings and descriptive studies. We compiled the only available telemetry data from wild camels worldwide.

Veterinary assessment for free-ranging Eurasian Black Vulture (Aegypius monachus) chicks in southeastern Mongolia.

Working as a veterinarian in remote field locations can be physically and intellectually challenging. A collaborative multi-disciplinary approach is often required for successful data collection. Technologies and methodologies frequently need to be modified to work in these harsh field environments.

The crucial contribution of veterinarians to conservation biology.

Conservation biology is a relatively new (began in the 1980s), value-based discipline predicated on the belief that biological diversity-from genes to populations to species to communities to ecosystems-is good and extinction is bad. Conservation biology grew from the recognition that the Earth has entered its sixth great extinction event, one that differs from previous great extinctions in that a single species-Homo sapiens-has caused this biodiversity crisis. A diverse, interacting set of variables drive current extinctions.

The value of enrichment to reintroduction success.

Reintroduction attempts have faced low, albeit improving, success rates, especially for threatened and endangered species reintroduced from captivity to the wild. This is not only a concern for conservation, as the low success of reintroduction also implies an animal welfare issue for the individuals concerned. Success rates are particularly low for species that live in complex social structures, require greater training during development, and exhibit higher levels of intelligence.
