Lyngdoh, S., Shrotriya, S., Goyal, S. P., Clements, H., Hayward, M. W., Habib, B. (2014). Prey Preferences of the Snow Leopard (Panthera uncia): Regional Diet Specificity Holds Global Significance for Conservation. Plos One, 9(2), 1–11.
Abstract: The endangered snow leopard is a large felid that is distributed over 1.83 million km2 globally. Throughout its range it relies on a limited number of prey species in some of the most inhospitable landscapes on the planet where high rates of human persecution exist for both predator and prey. We reviewed 14 published and 11 unpublished studies pertaining to snow leopard diet throughout its range. We calculated prey consumption in terms of frequency of occurrence and biomass consumed based on 1696 analysed scats from throughout the snow leopard’s range. Prey biomass consumed was calculated based on the Ackerman’s linear correction factor. We identified four distinct physiographic and snow leopard prey type zones, using cluster analysis that had unique prey assemblages and had key prey characteristics which supported snow leopard occurrence there. Levin’s index showed the snow leopard had a specialized dietary niche breadth. The main prey of the snow leopard were Siberian ibex (Capra sibrica), blue sheep (Pseudois nayaur), Himalayan tahr (Hemitragus jemlahicus), argali (Ovis ammon) and marmots (Marmota spp). The significantly preferred prey species of snow leopard weighed 5565 kg, while the preferred prey weight range of snow leopard was 36–76 kg with a significant preference for Siberian ibex and blue sheep. Our meta-analysis identified critical dietary resources for snow leopards throughout their distribution and illustrates the importance of understanding regional variation in species ecology; particularly prey species
that have global implications for conservation. |

Lovari, S., Ventimiglia, M., Minder, I. (2013). Food habits of two leopard species, competition, climate change and upper treeline: a way to the decrease of an endangered species? Ethology Ecology & Evolution, 25(4), 305–318.
Abstract: For carnivore species, spatial avoidance is one of the evolutionary solutions to
coexist in an area, especially if food habits overlap and body sizes tend to coincide. We reviewed the diets of two large cats of similar sizes, the endangered snow leopard (Panthera uncia, 16 studies) and the near-threatened common leopard (Panthera par- dus, 11 studies), in Asia. These cats share ca 10,000 km2 of their mountainous range, although snow leopards tend to occur at a significantly higher altitude than common leopards, the former being a cold-adapted species of open habitats, whereas the latter is an ecologically flexible one, with a preference for woodland. The spectrum of prey of common leopards was 2.5 times greater than that of snow leopards, with wild prey being the staple for both species. Livestock rarely contributed much to the diet. When the breadth of trophic niches was compared, overlap ranged from 0.83 (weight categories) to one (main food categories). As these leopard species have approximately the same size and comparable food habits, one can predict that competition will arise when they live in sympatry. On mountains, climate change has been elevating the upper forest limit, where both leopard species occur. This means a habitat increase for common leopards and a substantial habitat reduction for snow leopards, whose range is going to be squeezed between the forest and the barren rocky altitudes, with medium- to long-term undesirable effects on the conservation of this endangered cat |

Chalise, M. K. (2011). Snow Leopard (Uncia uncia), Prey Species and Outreach in Langtang National, Park, Nepal. Our Nature, (9), 138–145.
Abstract: Presence of snow leopard (Uncia uncia) in Langtang National Park was obscure till 2003. It was confirmed by a
research team trained for the wildlife biology in the field. Along with the study of ecology and behavior of snow leopard sufficient effort were made to generate data on pre species. The study also dealt with threat perceived for the leopard survival while basic unit of conservation- local outreach programs were also initiated. |

Conservation and climate change: Assessing the vulnerability of snow leopard habitat to treeline shift in the Himalaya. Biological Conservation, 150, 129–135.
Abstract: Climate change is likely to affect the persistence of large, space-requiring species through habitat shifts,
loss, and fragmentation. Anthropogenic land and resource use changes related to climate change can also impact the survival of wildlife. Thus, climate change has to be integrated into biodiversity conservation plans. We developed a hybrid approach to climate-adaptive conservation landscape planning for snow leopards in the Himalayan Mountains. We first mapped current snow leopard habitat using a mechanistic approach that incorporated field-based data, and then combined it with a climate impact model using a correlative approach. For the latter, we used statistical methods to test hypotheses about climatic drivers of treeline in the Himalaya and its potential response to climate change under three IPCC greenhouse gas emissions scenarios. We then assessed how change in treeline might affect the distribution of snow leopard habitat. Results indicate that about 30% of snow leopard habitat in the Himalaya may be lost due to a shifting treeline and consequent shrinking of the alpine zone, mostly along the southern edge of the range and in river valleys. But, a considerable amount of snow leopard habitat and linkages are likely to remain resilient to climate change, and these should be secured. This is because, as the area of snow leopard habitat fragments and shrinks, threats such as livestock grazing, retaliatory killing, and medicinal plant collection can intensify. We propose this approach for landscape conservation planning for other species with extensive spatial requirements that can also be umbrella species for overall biodiversity. 2012 Elsevier Ltd.

Manati, A. R. (2008). Fur trade of large cats and the question of the subspecies status of leopards in Afghanistan (Der Handel mit Fellen von Grosskatzen und die Abklärung der Unterartenfrage beim. Germany: University of Köln.
Abstract: Over a time of four years the bazars of Afghanistan were surveyed for furs of spotted wild cats, in particular leopards and snow leopards. In 2004 in Kabul a total of 28 furs of leopards were purchased by shopkeepers and 21 sold at an average price of 825 $. In the same year 25 furs of snow leopards were purchased and 19 sold to clients at an average price of 583 $. In 2006 at a single inspection double as many furs of leopards were found to be offered for sale in comparison to the whole year of 2004. Also prices had increased over the two years by 20 % to an average of 1037 $. Similarly the number of furs of snow leopards at 21 pieces was higher than in 2004, and the prices had increased to an average of 652 $. In 2007 investigations rendered more difficult, because the authorities had started to control the fur trade, and the results are not unequivocal. Clients were without any exception foreigners.
Surveys in 2004 in Mazar-e-Sharif, Kunduz, Takhar and Faiz Abad, in 2006 additionally in Baharak and Iskashem in the province of Badakhshan, revealed a regular trade in furs of spotted cats, however not as extensive as in Kabul. The most interesting finding was a fur of a cheetah in Mazar-e-Sharif, the first record of this species after 35 years. From the surveys can be concluded that leopards still exist in the whole range of its distribution area in Afghanistan. However they don't allow any conclusion on the population size and its threat by hunting. In contrast to the leopard there exists a recent estimation of the population size of the snow leopard, saying that there are still 100 to 200 snow leopards living in Afghanistan. On the basis of these figures as well as the numbers of furs traded annually a Population and Habitat Viability Analysis was conducted. The result of this analysis is alarming. It has to be assumed that the snow leopard will be extinct in Afghanistan within the next ten years. To improve the protection of spotted cats in Afghanistan it needs both, a better implementation of the existing legislation as well as an awareness campaign among potential clients, i. e. foreigners living in Afghanistan. The second part of this thesis deals with the question of subspecies of leopards in Afghanistan. Out of the 27 subspecies described four are believed to exist in Afghanistan. However, according to a molecularbiological revision of the species there occurs only one subspecies in Afghanistan, Panthera pardus saxicolor. To clarify the subspecies question various measures of furs had been taken in the bazars. The results revealed that the leopards in Afghanistan are the biggest of its species. However a further differentiation according to the area of origin within the country was not possible. Also the traditional differentiation on the basis of colours and patterns on the furs was not possible. In contrast to the molecularbiological investigations published not only samples of zoo animals were available in this study but also samples from the wild. The own results confim that almost all leopards from Afghanistan and Iran belong to one and the same subspecies, P. p. saxicolor. Only in the most eastern part of Afghanistan, the Indian leopard, Panthera pardus fusca, can be found. The International Studbook for the Persian Leopard was analysed. The whole population derives from a few founder animals, which were imported in the midth fifties from Iran and in the late sixties from Afghanistan. To avoid inbreeding later on the Iranian and the Afghan lines were mixed. A female imported in 1968 from Kabul to Cologne is represented in each of the more than 100 today living animals.Mixing the two lines subsequently is justified by the genetic results of this study. Recently acquired animals from the Caucasus, however, should be tested genetically before integrating them into the zoo population. |

Johnsingh, A. J. T. (2006). A roadmap for conservation in Uttaranchal.
Abstract: The enchanting state of Uttaranchal, carved out of Uttar Pradesh on 9th November 2000, has a total area of ca. 53,485 km2 with a population density of 160 persons/ km2, much lower than the national average of 324/km2. This young state can take pride in the fact that 13.42% of its area is under protected areas. The state has varied landscapes: snow-capped and conifer forest covered mountains in the north, forest covered foothills with numerous perennial rivers and streams, locally known as the bhabar tract which includes the Himalayan foothills and the Shivalik range. As a result, the land is home to a variety of fascinating wildlife such as the golden mahseer (Tor putitora), king cobra (Ophiophagus hanna), Himalayan monal (Lophophorus impejanus), great hornbill (Buceros bicornis), Himalayan tahr (Hemitragus jemlahicus), bharal (Pseudois nayaur), Himalayan musk deer (Moschus chrysogaster), goral (Nemorhaedus goral), elephant (Elephas maximus), snow leopard (Panthera uncia), leopard (P. pardus), black bear (Ursus thibetanus), and tiger (P. tigris). All across their range, most of these species are endangered. The potential of this state, with about 800 kilometers of riverine habitat, can only be surpassed by Arunachal Pradesh in terms of golden mahseer conservation. The mountains, bedecked with the scarlet flowers of rhododendron (Rhododendron arboreum) in the summer months, can be a veritable home to many forms of pheasants, mountain ungulates and carnivores, provided poaching for trade is eliminated and hunting for the pot is brought under control. The bhabar forests of this state, ca. 7,500 km2, extending between Yamuna and Sharda rivers (Fig. 1.), can easily support a population of about 1000 elephants and 200 tigers as long as this large habitat, now fragmented in three blocks, is managed and protected as one continuous habitat for wildlife. Six villages, gujjar settlements and encroachments need to be moved away from the main wildlife habitat which goes along the bhabar tract. Although the conservation of these habitats can eventually bring in immense benefits through well-planned ecotourism programmes that are rapidly catching up in the state, initial conservation efforts would need a substantial amount of funds.

Zhang, F., Jiang, Z., Zeng, Y., & McCarthy, T. (2007). Development of primers to characterize the mitochondrial control region of the snow leopard (Uncia uncia) (Vol. 7).
Abstract: The snow leopard (Uncia uncia) is a rare carnivore living above the snow line in central Asia. Using universal primers for the mitochondrial genome control region hypervariable
region 1 (HVR1), we isolated a 411-bp fragment of HVR1 and then designed specific primers near each end of this sequence in the conserved regions. These primers were shown to yield good polymerase chain reaction products and to be species specific. Of the 12 snow leopards studied, there were 11 segregating sites and six haplotypes. An identification case of snow leopard carcass (confiscated by the police) proved the primers to be a useful tool for forensic diagnosis in field and population genetics studies. |
