Title Natal dispersal and exploratory forays through atypical habitat in the mountain-bound snow leopard Type Journal Article
Year 2024 Publication Ecology Abbreviated Journal
Volume (down) 2024 Issue e4264 Pages 1-4
Keywords connectivity, Gobi Desert, landscape permeability, Mongolia, Panthera uncia, resistance, steppe
Abstract Understanding how landscapes affect animal movements is key to effective conservation and management (Rudnick et al., 2012; Zeller et al., 2012). Movement defines animal home ranges, where animals generally access resources such as food and mates, and also their dispersal and exploratory forays. These movements are important for individual survival and fitness through genetic exchange within and between populations and for colonization of unoccupied habitats (Baguette et al., 2013; MacArthur & Wilson, 1967). Dispersal and exploratory movements typically occur when young animals leave their natal range and establish more permanent home ranges (Greenwood, 1980; Howard, 1960). In mammals, natal dispersal of males is usually more frequent and happens over greater distances compared with that of females (Clobert et al., 2001; Greenwood, 1980).

Title In the shadows of snow leopards and the Himalayas: density and habitat selection of blue sheep in Manang, Nepal Type Journal Article
Year 2020 Publication Ecology and Evolution Abbreviated Journal
Volume (down) 2021 Issue 11 Pages 108-122
Keywords Annapurna Conservation Area, bharal, Panthera uncia, predator-prey, Pseudois nayaur
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.

Title Common and snow leopards share prey, but not habitats: competition avoidance by large predators Type Journal Article
Year 2013 Publication Journal of Zoology Abbreviated Journal
Volume (down) 291 Issue Pages 127-135
Keywords coexistence; resource partitioning; food habits; Panthera uncia; Panthera pardus.
Abstract Resource exploitation and behavioural interference underlie competition among

carnivores. Competition is reduced by specializing on different prey and/or spatiotemporal

separation, usually leading to different food habits. We predicted that

two closely related species of large cats, the endangered snow leopard and the

near-threatened common leopard, living in sympatry, would coexist through

habitat separation and exploitation of different prey species. In central Himalaya,

we assessed (2006–2010) habitat and diet overlap between these carnivores. The

snow leopard used grassland and shrubland, whereas the common leopard

selected forest. Contrary to our prediction, snow leopard and common leopard

preyed upon similar wild (Himalayan tahr, musk deer) and domestic species (Bos

spp., dogs). Dietary overlap between snow leopard and common leopard was 69%

(yearly), 76% (colder months) and 60% (warmer months). Thus, habitat separation

should be the result of other factors, most likely avoidance of interspecific

aggression. Habitat separation may not always lead to the use of different prey.

Avoidance of interspecific aggression, rather than exploitation of different

resources, could allow the coexistence of potentially competing large predators.

Title Co-occurrence of snow leopard, wolf and Siberian ibex under livestock encroachment into protected areas across the Mongolian Altai Type Journal Article
Year 2021 Publication Biological Conservatio Abbreviated Journal
Volume (down) 261 Issue 109294 Pages 1-14
Keywords Camera-trapping, Panthera uncia, Canis lupus, Capra sibirica, Occupancy, Human-wildlife conflicts, Activity pattern
Abstract In countries such as Mongolia, where globalization of the cashmere market has spurred herders to massively increase their livestock numbers, an important conservation concern is the effect of livestock encroachment on wildlife. This is especially important inside protected areas (PAs), which often represent the last refugia for threatened large mammals. We used camera-traps to sample four areas with different protection status across the Mongolian Altai Mountains, and targeted a predator-prey system composed of livestock, one large herbivore, the Siberian ibex, and two large carnivores, the snow leopard and the wolf. To determine the effect of livestock on habitat use by the wild species and their spatio-temporal co-occurrence we applied an occupancy framework explicitly developed for modelling interacting species. We recorded a widespread presence of domestic animals in the PAs, and observed avoidance of sites used by livestock by snow leopard and ibex, while wolves tended to co-occur with it. Snow leopard and ibex showed clear mutual co-occurrence, indicating a tight predator-prey relationship. Results provide evidence that, at the scale of sites sampled primarily to maximise snow leopard detections, grazing livestock interferes with wild species by inducing avoidance in snow leopards, and attraction in wolves. We suggest that (1) PAs management should enforce real grazing limitations on the ground, especially in the core areas of the parks; (2) new policies incorporating wildlife conservation into government subsidies to pastoralists should be envisaged, to prevent increasing displacement of snow leopards and ibex; (3) as wolves co- occurred with livestock, with the potential for human-wildlife conflicts, we encourage the use of a set of prevention techniques to mitigate livestock depredation.

Title Defining priorities for global snow leopard conservation landscapes Type Journal Article
Year 2019 Publication Biological Conservation Abbreviated Journal
Volume (down) 241 Issue 108387 Pages 1-10
Keywords Panthera uncia, Conservation prioritization, Landscape Conservation Unit, Connectivity, Linkage
Abstract The snow leopard (Panthera uncia) is an apex predator on the Tibetan Plateau and in the surrounding mountain ranges. It is listed as Vulnerable in the IUCN's Red List. The large home range and low population densities of this species mandate range-wide conservation prioritization. Two efforts for range-wide snow leopard conservation planning have been conducted based on expert opinion, but both were constrained by limited knowledge and the difficulty of evaluating complex processes, such as connectivity across large landscapes. Here, we compile > 6000 snow leopard occurrence records from across its range and corresponding environmental covariates to build a model of global snow leopard habitat suitability. Using spatial prioritization tools, we identi!ed seven large continuous habitat patches as global snow leopard Landscape Conservation Units (LCUs). Each LCU faces differing threat levels from poaching, anthropogenic development, and climate change. We identi!ed ten po- tential inter-LCU linkages, and centrality analysis indicated that Tianshan-Pamir-Hindu Kush-Karakorum, Altai, and the linkage between them play a critical role in maintaining the global snow leopard habitat connectivity.

Title A key for the identification of the hair of mammals of a snow leopard (Panthera uncia) habitat in Nepal Type Journal Article
Year 1993 Publication Journal of Zoology London Abbreviated Journal
Volume (down) 231 Issue 1 Pages 71-93
Keywords Nepal; snow leopard; scats; Hair; diet; identification; Panthera-uncia; browse; panthera uncia; panthera; uncia; 780
Abstract Analysis of prey remains in scats, particularly hairs, in widely used to study diet of mammalian predators, but identification of hair is often difficult because hair structures vary considerably both within and between species. Use of photographic reference of diagnostically important hair structures from mammals occurring in a predator's habitat has been found to be convenient for routine identification. A photographic reference key was developed for the identification of hairs of the mammals known to occur in a snow leopard (Panthera uncia) habitat in the Annapurna Conservation Area, Nepal. The key included a photographic reference of the diagnostic hair structures of nine species of wild and five species of domestic mammals. The cross-sectional appearance, shape and arrangement of medulla, the ratio of cortex to medulla, and the form and distribution of pigment in medulla and cortex were important diagnostic aids in the identification of hairs.

Title Snow leopard predation in a livestock dominated landscape in Mongolia Type Journal Article
Year 2015 Publication Biological Conservation Abbreviated Journal
Volume (down) 184 Issue Pages 251-258
Keywords Gobi desert, GPS collar, Kill rate, Panthera uncial, Prey choice, Wildlife conflict
Abstract Livestock predation is an important cause of endangerment of the snow leopard (Panthera uncia) across

its range. Yet, detailed information on individual and spatio-temporal variation in predation patterns of

snow leopards and their kill rates of livestock and wild ungulates are lacking.

We collared 19 snow leopards in the Tost Mountains, Mongolia, and searched clusters of GPS positions

to identify prey remains and estimate kill rate and prey choice.

Snow leopards killed, on average, one ungulate every 8 days, which included more wild prey (73%) than

livestock (27%), despite livestock abundance being at least one order of magnitude higher. Predation on

herded livestock occurred mainly on stragglers and in rugged areas where animals are out of sight of herders.

The two wild ungulates, ibex (Capra ibex) and argali (Ovis ammon), were killed in proportion to their

relative abundance. Predation patterns changed with spatial (wild ungulates) and seasonal (livestock)

changes in prey abundance. Adult male snow leopards killed larger prey and 2–6 times more livestock

compared to females and young males. Kill rates were considerably higher than previous scat-based estimates, and kill rates of females were higher than kill rates of males. We suggest that (i) snow leopards

prey largely on wild ungulates and kill livestock opportunistically, (ii) retaliatory killing by livestock herders

is likely to cause greater mortality of adult male snow leopards compared to females and young

males, and (iii) total off-take of prey by a snow leopard population is likely to be much higher than previous

estimates suggest.

Title POTENTIAL HABITAT OF SNOW LEOPARD (PANTHERA UNCIA, FELINAE) IN SOUTH SIBERIA AND ADJACENT TERRITORIES BASED ON THE MAXIMUM ENTROPY DISTRIBUTION MODEL Type Journal Article
Year 2019 Publication Abbreviated Journal
Volume (down) 98 Issue 3 Pages 332-342
Keywords Snow leopard, irbis, Panthera uncia, Maxent, habitat model, potential habitat
Abstract The snow leopard is an endangered large felid inhabiting highlands of 12 Asian countries. It is distributed

across vast territories and adequate modern methods are required for mapping its potential habitats. The goal

of the present study is to create a model of snow leopard potential habitat within the northern part of its range

in Russia (and adjacent territories of Mongolia, China and Kazakhstan). More than 5 years of observations

(total number of presence points = 449), environmental variables and the maximum entropy distribution

method (Maxent) are used. The resulting map demonstrates that a suitable habitat (probability of the animal�s

presence between 0.5 and 1) of the northern population of snow leopard in Russia occupies 16500 km2

with a buffer of transient territories (probability between 0.25 and 0.49) covering 32800 km2. Most of a suitable

habitat within the study area is associated with the Altai Mountains, Western Sayan Mountains, Sangilen

Plateau, Tsagan-Shibetu and Shapshal. One third of the suitable habitat lies within areas of a varying protection

status. The results of modeling are of importance both for scientists and conservation managers, as they

allow for leopard occurrence to be predicted, supporting research on and the conservation of the species.

Title Snow leopards and blue sheep in Nepal: Densities and predator: Prey ratio Type Miscellaneous
Year 1994 Publication Journal of Mammalogy Abbreviated Journal
Volume (down) 75 Issue Pages 998-1004
Keywords snow leopard,Panthera uncia,blue sheep,Pseudois nayaur,density,predator:prey ratio,harvest rate,livestock predation,Nepal
Abstract I studied snow leopards (Panthera uncia) and blue sheep (Pseudois nayaur) in Manang District, Annapurna Conservation Area, Nepal, to estimate numbers and analyze predatorprey interactions. Five to seven adult leopards used the 105-km2 study area, a density of 4.8 to 6.7 leopards/100 km2. Density of blue sheep was 6.6-10.2 sheep/km2, and biomass density was 304 kg/km2. Estimated relative biomass consumed by snow leopards suggested that blue sheep were the most important prey; marmots (Marmota himalayana) also contributed significantly to the diet of snow leopards. Snow leopards in Manang were estimated to harvest 9-20% of total biomass and 11-24% of total number of blue sheep annually. Snow leopard :blue sheep ratio was 1 :1 14-1 :159 on a weight basis, which was considered sustainable given the importance of small mammals in the leopard's diet and the absence of other competing predators.
