Wolf, M., & Ale, S. (2009). Signs at the Top: Habitat Features Influencing Snow Leopard Uncia Uncia Activity in Sagarmatha National Park, Nepal. Journal of Mammalogy, 90(3), 604–611.
Abstract: We used logistic regression to examine factors that affected the spatial distribution of sign (scrapes, feces, footprints, spray or scent marks, and rubbing sites) in a newly reestablished population of snow leopards (Uncia uncia) in Sagarmatha (Mount Everest) National Park, Nepal. Our results indicate that terrain and human activity were the most important factors determining the spatial distribution of leopard activity, whereas presence of their major prey species (Himalayan tahr [Hemitragus jemlahicus]) had only a moderate effect. This suggests that localities at which these animals are active represent a trade-off between suitable habitat and avoidance of potential risk from anthropogenic origins. However, the influence of prey presence was likely underestimated because of the methodology used, and likely weighed in the trade-off as well.

Filla, M., Lama, R. P., Ghale, T. R., Signer, J., Filla, T., Aryal, R. R., Heurich, M., Waltert, M., Balkenhol, N., Khorozyan, I. (2020). In the shadows of snow leopards and the Himalayas: density and habitat selection of blue sheep in Manang, Nepal. Ecology and Evolution, 2021(11), 108–122.
Abstract: There is a growing agreement that conservation needs to be proactive and pay increased attention to common species and to the threats they face. The blue sheep (Pseudois nayaur) plays a key ecological role in sensitive high-altitude ecosystems of Central Asia and is among the main prey species for the globally vulnerable snow leopard (Panthera uncia). As the blue sheep has been increasingly exposed to human pressures, it is vital to estimate its population dynamics, protect the key populations, identify important habitats, and secure a balance between conservation and local livelihoods. We conducted a study in Manang, Annapurna Conservation Area (Nepal), to survey blue sheep on 60 transects in spring (127.9 km) and 61 transects in autumn (134.7 km) of 2019, estimate their minimum densities from total counts, compare these densities with previous estimates, and assess blue sheep habitat selection by the application of generalized additive models (GAMs). Total counts yielded minimum density estimates of 6.0–7.7 and 6.9–7.8 individuals/km2 in spring and autumn, respectively, which are relatively high compared to other areas. Elevation and, to a lesser extent, land cover indicated by the normalized difference vegetation index (NDVI) strongly affected habitat selection by blue sheep, whereas the effects of anthropogenic variables were insignificant. Animals were found mainly in habitats associated with grasslands and shrublands at elevations between 4,200 and 4,700 m. We show that the blue sheep population size in Manang has been largely maintained over the past three decades, indicating the success of the integrated conservation and development efforts in this area. Considering a strong dependence of snow leopards on blue sheep, these findings give hope for the long-term conservation of this big cat in Manang. We suggest that long-term population monitoring and a better understanding of blue sheep–livestock interactions are crucial to maintain healthy populations of blue sheep and, as a consequence, of snow leopards.

Zhiryakov V.A. (1979). The influence of large predators on wild mammal populations in the Almaty nature reserve.
Abstract: There are following large predators in the Almaty nature reserve: wolf (5-6), snow leopard (single occasions), Turkistan lynx (single occasions), and Tien Shan brown bear (15-20). The share of wild mammals (roe-deer, ibex, wild boar, argali, gazelle, moral, and badger) being eaten by predators is 18.2 percent, about 60 percent of the entire prey falling to the share of wolf.

D'Arcy, P. (2000). Endangered species being slaughtered in Russia's far east: WWF.
Abstract: The World Wide Fund for Nature (WWF) on Saturday accused Russia's far eastern regions of slaughtering endangered species for trade or to protect livestock, the Interfax news agency reported. The international organisation's Moscow branch told the news agency that it could no longer afford the cost of sending out teams of rangers to protect snow leopards from “revenge killing” and poaching.

Bhatnagar, Y. V., Mathur, V. B., & McCarthy, T. (2002). A Regional Perspective for Snow Leopard Conservation In the Indian Trans-Himalaya.. Islt: Islt.
Abstract: The Trans-Himalaya is a vast biogeographic region in the cold and arid rain-shadow of
the Greater Himalaya and is spread over three Indian states. From the conservation standpoint this region has several unique characteristics. Unlike most other biogeographic regions of the country, it has wildlife, including large mammals, spread over the entire region. Another feature is that the harsh climate and topography provides limited agricultural land and pastures, all of which are currently utilized by people. The harsh environment has given rise to a specialized assemblage of flora and fauna in the region that include the endangered snow leopard, a variety of wild sheep and goat, Tibetan antelope, Tibetan gazelle, kiang and wild yak. The snow leopard is one of the most charismatic species of the Trans-Himalaya. This apex predator, with a wide distribution, has ecological importance and international appeal, and is eminently suitable to be used as both a 'flagship' and an 'umbrella species' to anchor and guide conservation efforts in the Trans-Himalayan region. Among the 10 Biogeographic Zones in the country, the Trans-Himalaya has a comparatively large Protected Area (PA) coverage, with over 15,000 km2 (8.2 %) of the geographical area under the network. In spite of this, the bulk of the large mammal populations still exist outside the PAs, which include highly endangered species such as snow leopard, chiru, wild yak, Ladakh urial, kiang and brown bear. Given the sparse resource availability in the Trans-Himalaya and the existing human use patterns, there are few alternatives that can be provided to resource dependent human communities in and around PAs. The existing PAs themselves pose formidable conservation challenges and a further increase in their extent is impractical. The problem is further compounded by the fact that some of the large PAs have unclear boundaries and include vast stretches that do not have any direct wildlife values. These issues call for an alternative strategy for conservation of the Trans-Himalayan tracts based on a regional perspective, which includes reconciling conservation with development. In this paper we stress that conservation issues of this region, such as competition for forage between wild and domestic herbivores and human-wildlife conflicts need to be addressed in a participatory manner. We suggest an alternative scheme to look at the zonation of existing PAs and also the Trans-Himalayan region as a whole, to facilitate better conservation in the region. Also, we emphasize that there is a vital need for additional resources and a formal setup for regional planning and management under a centrally sponsored scheme such as the 'Project Snow Leopard'. |

Ale, S., & Whelan, C. (2008). Reappraisal of the role of big, fierce predators.
Abstract: The suggestion in the early 20th century that top predators were a necessary component of ecosystems because they hold herbivore populations in check and promote biodiversity was at Wrst accepted and then largely rejected. With the advent of Evolutionary Ecology and a more full appreciation of direct and indirect effects of top predators, this role of top predators is again gaining acceptance. The previous views were predicated upon lethal effects of predators but largely overlooked their non-lethal effects. We suggest that
conceptual advances coupled with an increased use of experiments have convincingly demonstrated that prey experience costs that transcend the obvious cost of death. Prey species use adaptive behaviours to avoid predators, and these behaviours are not cost-free. With predation risk, prey species greatly restrict their use of available habitats and consumption of available food resources. Effects of top predators consequently cascade down to the trophic levels below them. Top predators, the biggies, are thus both the targets of and the means for conservation at the landscape scale. |

Sokolov G.A. (2003). Predatory mammals of Central Siberia, status of populations, influence of anthropogenic factors.
Abstract: The species resources of Siberia's fauna decrease from south to north. The highest diversity of species is observed in the mountain systems, the lowest in sub-zones of south and central taiga and steppe zone, where the cat family species are absent. During the last 50 150 years number of species has decreased two- to tenfold. Imperfect hunting management, farming, and mining operations resulted in transformation of the animal habitats. Population of fox, polecat, and sable has reduced; snow leopard and dhole becoming endangered species. If current tendencies continue to develop some species will disappear in the region in decades to come.

Sunquist, F. (1997). Where cats and herders mix. (snow leopards in Tibet and Mongolia). International Wildlife, 27(1), 27–33.
Abstract: The snow leopard inhabits a huge range of territory which encompasses some of Central Asia's most bleak and inhospitable terrains. The animal herders in these regions are desperately poor and yet they have agreed to cooperate with conservation groups in protecting the snow leopard. The World Wildlife Foundation has worked to create a refuge on the Pakistan-China border. Sheep herders near Askole, a village in the Baltistan region of northern Paksitan, drive their flocks past stone enclosures. The area is also home to snow leopards. With their natural prey dminished, leopards in 13 countries of central Asia occasionally feed on livestock, putting the cats on a collision course with mountain peoples.
