Murray, D., Kapke, C., Evermann, J., & Fuller, T. (1999). Infectious disease and the conservation of free-ranging large carnivores. Animal Conservation, 2, 241–254.
Abstract: Large carnivores are of vital importance to the stability and integrity of most ecosystems, but recent declines in free-ranging populations have highlighted the potentially devastating effect of infectious diseases on their conservation. We reviewed the literature on infectious diseases of 34 large (maximum body mass of adults >20 kg) terrestrial carnivore species, 18 of which are considered to be threatened in the wild, and examined reports of antibody prevalence (seroprevalence) and cases of infection, mortality and population decline. Of 52 diseases examined, 44% were viral, 31% bacterial and the remainder were protozoal or fungal. Many infections were endemic in carnivores and/or infected multiple taxonomic families, with the majority probably occurring via inhalation or ingestion. Most disease studies consisted of serological surveys for disease antibodies, and antibody detection tended to be widespread implying that exposure to micro-organisms was common. Seroprevalence was higher in tropical than temperate areas, and marginally higher for infections known to occur in multiple carnivore groups. Confirmation of active infection via micro-organism recovery was less common for ursids than other taxonomic groups. Published descriptions of disease-induced population decline or extinction were rare, and most outbreaks were allegedly the result of direct transmission of rabies or canine distemper virus (CDV) from abundant carnivore species to less-common large carnivores. We conclude that the threat of disease epidemics in large carnivores may be serious if otherwise lethal infections are endemic in reservoir hosts and transmitted horizontally among taxa. To prevent or mitigate future population declines, research efforts should be aimed at identifying both the diseases of potential importance to large carnivores and the ecological conditions associated with their spread and severity.

Abstract: In 1998, under the WWF Altai-Sayans ecoregion conservation program, traces of snow leopard were detected in the ridges of Tsaran-Shibetu and Shipshal. The density of vital activity traces is comparable with those in northern Mongolia.

Abstract: Abstract Wild Bactrian camels Camelus bactrianus ferus are endangered. Surveys over the past several decades suggest a marked decline in camel numbers and reproductive success. However, most surveys were made using methods that precluded rigorous population estimation. The need for more accurate surveys resulted in an aerial survey of known and suspected camel habitat in Mongolia during March 1997. We estimated density, group density and population size of large mammals in south-western Mongolia using the interactive computer program DISTANCE. We recorded sufficient data for population modelling of wild Bactrian camels, goitred gazelles Gazella subgutturosa, Asian wild asses Equus hemionus and argali sheep Ovis ammon. We observed 277 camels in 27 groups (mean group size = 10.269 +- 2.38 SE camels: group). Modelling yielded a population estimate of 198 +- 802 SE camels in the survey area. Population modelling for other ungulates yielded estimates of 6046 +- 1398 SE goitred gazelles, 1674 +- 506 SE Asian wild asses and 909 +- 303 SE argalis. Discrepancies between population estimates of ungulates in our survey and previous surveys are discussed with regard to methods used and robustness of results obtained. We also discuss conservation implications for wild Bactrian camels and other Mongolian ungulates.

(1998). Biological diversity conservation. National strategy and action plan of the Republic of Uzbekistan.
Abstract: The National strategy and action plan of the Republic of Uzbekistan was signed on April 1, 1998. Snow leopard was included in the list of rare and endangered animal species and referred to category 2 a rare, not endangered species. It is distributed in highlands of the West Tien Shan and Pamiro-Alay. Its population is 30-50 animals. Snow leopard is protected in the Chatkal, Gissar nature reserve, and Ugam-Chatkal national park.

Abstract: The author offers advice on how a captive-raised snow leopard cub could be acclimated to humans so it could be used as a zoo “ambassador”. The cub had negative experiences with humans and lacked socialization with other animals and conspecifics. Methods of avoiding and redirecting the cub's aggressive behavior are suggested. lgh.

Koshkarev E. (1998). Critical Ranges as Centres of Biodiversity (Vol. N 14).
Abstract: A high percentage of rare species in Central Asia experience limited conditions for distribution. Geographic centers with higher species diversity are generally constrained in terms of territory: they are formed when ranges overlap. But in Central Asia and along its borders with Russia, centers of biodiversity overlap at the very marginal edges of ranges. Central Asian species cross into Russian territory, where desert and steppe are replaced by thick forest. Here the northern borders of their ranges are sharply fragmented and isolated. Typical examples for Central Asia are the ranges of the cheetah (Acinonyx jubatus), Asian leopard (Panthera pardus caucasica), striped hyena (Hyaena hyaena), Bukhara deer (Census elaphus bactrianus), markhor (Capra falconeri), blue sheep (Pseudois nayauf) and argali (Ovis ammon). In Russia are the Altai subspecies of argali, the Siberian argali (O.a.ammon), the mountain goat (Capra sibirica), Mongolian gazelle (Procapra gutturosa), snow leopard (Uncia uncia), Pallas' cat (Felis manul), dhole (Cuon alpinus), grey marmot (Marmota baibacina), Mongolian marmot (M. sibirica) and tolai hare (Lepus tolai). Where the numbers o f individuals has fallen to extreme lows, the most effective mechanism for species survival may be supporting the integrity of ranges, in order to preserve population exchanges between neighboring groups. The geographic location of reserves and other protected territories is vitally important for the survival of Central Asian species, given the acute fragmentation of their ranges. These reserves should include significant, viable centers of population the key places. Wherever the creation of permanent protected territories is impossible, a new tactic must be found, such as introducing temporary limitations on the use of land for agriculture and hunting. But all protected territories, whether temporary or permanent, should be connected, forming a core and periphery. The marginal range areas must not be forgotten, if total protection of endangered populations is to be accomplished.
