(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.
Ale, S., & Brown, J. (2007). The contingencies of group size and vigilance (Vol. 9).
Abstract: Background: Predation risk declines non-linearly with one's own vigilance and the vigilance of others in the group (the 'many-eyes' effect). Furthermore, as group size increases, the individual's risk of predation may decline through dilution with more potential victims, but may increase if larger groups attract more predators. These are known, respectively, as the dilution effect and the attraction effect.
Assumptions: Feeding animals use vigilance to trade-off food and safety. Net feeding rate declines linearly with vigilance.
Question: How do the many-eyes, dilution, and attraction effects interact to influence the relationship between group size and vigilance behaviour?
Mathematical methods: We use game theory and the fitness-generating function to determine the ESS level of vigilance of an individual within a group.
Predictions: Vigilance decreases with group size as a consequence of the many-eyes and dilution effects but increases with group size as a consequence of the attraction effect, when they act independent of each other. Their synergetic effects on vigilance depend upon the relative strengths of each and their interactions. Regardless, the influence of other factors on vigilance – such as encounter rate with predators, predator lethality, marginal value of energy, and value of vigilance – decline with group size.
Anonymous. (2001). Snow leopard in Mongolia. Ulaanbaatar, Mongolia.
Abstract: This documents contains a review of the snow leopard's distribution, status and habitat in Mongolia, describes threats and conservation needs of the species, and outlines presently implemented actions. Five major threats are identified: 1) Poaching 2) loss of prey 3) degradation, fragmentation and loss of habitat 4) conflict with herders 5) lack of public awareness. Actions to mitigate the five major threats are recommended and future conservation priorities are set.

Abstract: In this study, we investigated the cross-reactivity pattern of IgE and IgG4 antibodies to the major feline allergen, Fel d I. We studied the IgE and IgG4 response of 11 cat-allergic patients against Fel d I-like structures in eight members of the Felidae family: ocelot, puma, serval, siberian tiger, lion, jaguar, snow leopard, and caracal. Hair from these “big cats” was collected, extracted, and used in a RAST system and histamine-release test. By means of a RAST-inhibition assay with affinity-purified Fel d I from cat dander, it was established that, in the Felidae species, a Fel d I equivalent is present that reacts with IgE and IgG4 antibodies. We found that all patients had cross-reacting IgE antibodies to seven of the Felidae tested; no IgE antibodies reactive with the caracal were found. Eight of 10 patients with IgG4 antibodies directed to cat dander also had IgG4 antibodies directed to several Felidae species, including the caracal. However, the correlation between the IgE and the IgG4 antibody specificity was low, indicating that, in the case of Fel d I IgE and IgG4, antibodies do not necessarily have the same specificity.
Ferretti, F., Lovari, S. (2016). Predation may counteract climatic change as a driving force for movements of mountain ungulates.
Abstract: Temperature variations are expected to influence altitudinal movements of mountain herbivores and, in
turn, those of their predators, but relevant information is scarce. We evaluated monthly relationships
between temperature and altitude used by a large mountain-dwelling herbivore, the Himalayan tahr
Hemitragus jemlahicus, and its main predator, the snow leopard Panthera uncia, in an area of central
Himalaya for five consecutive years (2006–2010). In contrast to expectations, there was no significant
direct relationship between altitude of tahr sightings and temperature. The mean altitude of tahr sightings
decreased by c. 200 m throughout our study. As expected, snow leopard movements tracked those of tahr,
although the core area of the snow leopard did not move downwards. Tahr remained the staple of the
snow leopard diet: we suggest that the former did not move upwards in reaction to higher temperature
to avoid encounters with the latter. Avoidance of competition with the larger common leopard Panthera
pardus at lower altitudes could explain why snow leopards did not shift their core area downwards.
Apparently, interspecific interactions (predation; competition) influenced movements of Himalayan tahr
and snow leopards more than climatic variations.

Gurung, G. T. K. (2004). Snow Leopard (Uncia uncia) and Human Interaction in Phoo Village in the Annapurna Conservation Area, Nepal.
Abstract: Phoo village in the Annapurna Conservation Area (ACA) in Nepal is located at 4,052 m als physically
in the central north of the country. Livestock keeping is the main activity of the people for making a
living amidst a conflict with snow leopard (Uncia uncia). Each year snow leopard kills a number of
livestock resulting significant economic losses for the poor people living in this remote area. Unless
the people – snow leopard conflict is well understood and appropriate conflict management activities
are implemented, the long run co-existence between people and snow leopard – especially the
existence of snow leopard in this part of the world -will be in question. This has now become an
utmost important as the aspiration of the people for economic development has risen significantly and
the area has been opened to tourism since spring 2002. In addition to this, the globalisation process has
directly and indirectly affected the traditional resource management practices and co-existence
strategies of many traditional societies including Phoo.
The livestock depredation for 3 years (2001 – 2004) by snow leopard was studied by interviewing the
herders to understand the responsible and specific bio-physical and socio-economic factors. The study
revealed that goats are most depredated species followed by sheep. Winter months (January – April)
and winter pastures are most vulnerable to snow leopard predation. Presence of bushes, forest and
boulders make good hides for snow leopard resulting into high depredation. The study also showed
that a lax animal guarding system was significantly responsible for high livestock depredation by snow
The study showed that improvement in livestock guarding system should be adopted as the most
important activity. However despite the importance of livestock in the economy of Phoo it is still not
well understood why the herders neglect for proper livestock guarding. This requires further study.
Proper guarding system is required especially in winter season in winter pastures. It is also suggested
that there should be changes in the composition of livestock species by promoting more yaks and
discouraging or minimising goats. Yaks and large animals are less depredated and small animals like
goats and sheep are highly depredated by snow leopard. A trend was also observed in Phoo village
where there is an increase in the number of yaks and a decrease in the number of goats over last few
years. This could be a management response of the herders to livestock depredation. Other protective
measures of the livestock at the corrals have also been recommended including promotion of guard
dogs and other measures.
Since the area is opened for tourism, it is suggested that the tourism opportunity for the economic
development of the area should be grasped so that the heavy dependence on livestock raising would be
minimised. This will help minimise the number of human – snow leopard conflicts.

Abstract: Livestock depredation is emerging as a significant issue across the Himalaya, including the Hemis National Park (HNP) in Ladakh. Some consider that this protected area harbors the best snow leopard population in India, but local herders perceive the endangered snow leopard as a serious threat to their livelihood.
Jackson, R., Ahlborn, G.G. (1986). Appendix: Snow leopard managment recommendations provided to HMG in: Himalayan Snow Leopard Project: Final Progress Report, Phase I. Report: 1-7. Himalayan.
Abstract: Preliminary recommendations for the management of snow leopard and its prey are provided for the Langu Valley segment of the Shey-Pkoksundo National Park. Park-wide and country-wide conservation options and management recommendations await results of the surveys scheduled for 1987. The following management objectives are formulated: 1) Protection and ultimate restoration of all natural communities within the area 2) Special protection measures for snow leopard and musk deer (strict control of hunting and livestock grazing) 3) Secure natural resources around local villages 4) Respect traditional rights of villagers, while controlling high impact human activities 5) Secure cooperation of local people. These objectives are refined and recommendations for concrete conservation actions are made.

Kazensky, C. A., Munson, L., & Seal, U. S. (1998). The effects of melengestrol acetate on the ovaries of captive wild felids. Journal-of-Zoo-and-Wildlife-Medicine, 29(1), 1–5.
Abstract: Melengestrol acetate (MGA) is the most widely used contraceptive in zoo felids, but the mechanism of contraception and the pathologic effects have not been investigated. For this study, the effects of MGA on folliculogenesis were assessed, and the association of MGA with ovarian lesions was evaluated. Comparisons were made among the histopathologic findings in the ovaries from 88 captive wild felids (representing 15 species) divided into three groups: 37 currently contracepted with MGA, eight previously exposed to MGA, and 43 never contracepted. Ninety-one percent of the felids evaluated had tertiary follicles, and no differences were noted between contracepted and uncontracepted cats. Some MGA-contracepted cats also had corpora lutea indicating recent ovulation. These results indicate that folliculogenesis is not suppressed by current doses of MGA and ovulation occurred in some cats. Therefore, the contraceptive actions of MGA do not occur by suppressing folliculogenesis, and MGA-contracepted felids likely have endogenous estrogens that may confound progestin effects on the uterus. Cystic rete ovarii was the most common pathologic finding, but they were not more prevalent in MGA-contracepted cats. These findings indicate that MGA is not associated with ovarian disease, including ovarian cancer, in contrast to the uterine lesions noted in MGA-treated cats.
