  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 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 The timing of breeding and independence for snow leopard females and their cubs. Type Journal Article
  Year 2020 Publication Mammalian Biology Abbreviated Journal  
  Volume Issue Pages  
  Keywords Age of independence; Life-history trade-offs; Panthera uncia; Parental care; Pre-dispersal behavior; Separation; Subadult  
  Abstract Significant knowledge gaps persist on snow leopard demography

and reproductive behavior. From a GPS-collared population in Mongolia,

we estimated the timing of mating, parturition and independence. Based

on three mother–cub pairs, we describe the separation phase of the cub

from its mother as it gains independence. Snow leopards mated from

January–March and gave birth from April–June. Cubs remained with their

mother until their second winter (20–22 months of age) when cubs started

showing movements away from their mother for days at a time. This

initiation of independence appeared to coincide with their mother mating

with the territorial male. Two female cubs remained in their mothers’

territory for several months after initial separation, whereas the male

cub quickly dispersed. By comparing the relationship between body size

and age of independence across 11 solitary, medium-to-large felid

species, it was clear that snow leopards have a delayed timing of

separation compared to other species. We suggest this may be related to

their mating behavior and the difficulty of the habitat and prey capture

for juvenile snow leopards. Our results, while limited, provide

empirical estimates for understanding snow leopard ecology and for

parameterizing population models.

  Title Guidelines for Telemetry Studies on Snow Leopards Type Journal Article
  Year 2022 Publication Animals Abbreviated Journal  
  Volume 12 Issue 1663 Pages 1-12  
  Keywords animal welfare; capture; collar; felid; GPS; immobilization; Panthera uncia; trapping  
  Abstract Animal-borne tracking devices have generated a wealth of new knowledge, allowing us to better understand, manage and conserve species. Fitting such tracking devices requires that animals are captured and often chemically immobilized. Such procedures cause stress and involve the risk of injuries and loss of life even in healthy individuals. For telemetry studies to be justifiable, it is vital that capture operations are planned and executed in an efficient and ethical way. Project objectives must be clearly articulated to address well-defined knowledge gaps, and studies designed to maximize the probability of achieving those goals. We provide guidelines for how to plan, design, and implement telemetry studies with a special emphasis on snow leopards that are typically captured using foot snares. We also describe the necessary steps to ensure that captures are conducted safely, and with minimal stress to animals.

  Title Sex specific seasonal variation in puma and snow leopard home range utilization Type Journal Article
  Year 2018 Publication Ecosphere Abbreviated Journal  
  Volume 9 Issue 8 Pages 1-14  
  Keywords Cougar, female choice, LoCoH, mating tactics, Panthera Uncia, Puma concolor, spacing pattern, territoriality  
  Abstract Territory size is often larger for males than for females in species without biparental care. For large solitary carnivores, this is explained by males encompassing a set of female territories to monopolize their reproduction during mating (area maximization). However, males are expected to behave more like females outside of breeding, with their area utilization being dependent on the range required to secure food resources (area minimization). To examine how male and female solitary carnivores adjust their spatial organization during the year as key resources (mates and prey) change, we radio&#8208;collared 17 pumas (Puma concolor; nine males and eight females) and 14 snow leopards (Panthera uncia; seven males and seven females) and estimated home range size and overlap on two temporal scales (annual vs. monthly). Contrary to expectation, we found no evidence that males monopolized females (the mean territory overlap between females and the focal male during the mating season was 0.28 and 0.64 in pumas and snow leopards, respectively). Although male&#65533;male overlap of annual home ranges was comparatively high (snow leopards [0.21] vs. pumas [0.11]), monthly home range overlaps were small (snow leopards [0.02] vs. pumas [0.08]) suggesting strong territoriality. In pumas, both males and females reduced their monthly home ranges in winter, and at the same time, prey distribution was clumped and mating activity increased. In snow leopards, females showed little variation in seasonal home range size, following the seasonal stability in their primary prey. However, male snow leopards reduced their monthly home range utilization in the mating season. In line with other studies, our results suggest that female seasonal home range variation is largely explained by changes in food resource distribution. However, contrary to expectations, male territories did not generally encompass those of females, and males reduced their home ranges during mating. Our results show that male and female territorial boundaries tend to intersect in these species, and hint at the operation of female choice and male mate guarding within these mating systems.

  Title Snow leopard predation in a livestock dominated landscape in Mongolia Type Journal Article
  Year 2015 Publication Biological Conservation Abbreviated Journal  
  Volume 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 Predation Patterns and Hunting Behaviour of Snow Leopards: Insights from an Ibex Hunt Type Journal Article
  Year 2023 Publication Snow Leopard Reports Abbreviated Journal  
  Volume Issue Pages 6-9  
  Keywords ambush, Capra sibirica, kill site, mountain, Panthera uncia  
  Abstract The hunting behaviours of the snow leopard (Panthera uncia) are poorly understood. In this note, we describe the successful hunt of an adult male ibex (Capra sibirica) by a known male snow leopard in Tost Mountains, Mongolia. The hunt started in a mountain slope close to three large boulders and progressed downhill for 115 m until it concluded at the bottom of a drainage. By comparing the habitat where the ibex was killed to the kill sites of 158 ibex and 17 argali (Ovis ammon) that were killed by GPS-collared snow leopards, we demonstrate that the majority (62%) of these kills occurred in drainages. We propose that in successful hunts, snow leopards commonly ambush from above, causing prey individuals to typically flee downhill. Thereby the prey maintain their momentum and it is not until they are slowed down upon reaching the bottom of the drainage that the snow leopards are able to subdue them.

  Title Land sharing is essential for snow leopard conservation Type Journal Article
  Year 2016 Publication Biological Conservation Abbreviated Journal  
  Volume Issue 203 Pages 1-7  
  Keywords Home range, LoCoH, Mongolia, Panthera uncial, Protected areas, Land sparing  
  Abstract Conserving large carnivores in an increasingly crowded planet raises difficult challenges. A recurring debate is whether large carnivores can be conserved in human used landscapes (land sharing) or whether they require specially designated areas (land sparing). Here we show that 40% of the 170 protected areas in the global range of the snow leopard (Panthera uncia) are smaller than the home range of a single adult male and only 4– 13% are large enough for a 90% probability of containing 15 or more adult females. We used data from 16 snow leopards equipped with GPS collars in the Tost Mountains of South Gobi, Mongolia, to calculate home range size and overlap using three different estimators: minimum convex polygons (MCP), kernel utility distributions (Kernel), and local convex hulls (LoCoH). Local convex hull home ranges were smaller and included lower proportions of unused habitats compared to home ranges based on minimum convex polygons and Kernels. Intra-sexual home range overlapwas low, especially for adult males, suggesting that snowleopards are territorial. Mean home range size based on the LoCoH estimates was 207 km2 ± 63 SD for adult males and 124 km2 ± 41 SD for adult females. Our estimates were 6–44 times larger than earlier estimates based on VHF technology when comparing similar estimators, i.e. MCP. Our study illustrates that protected areas alone will not be able to conserve predatorswith large home ranges and conservationists and managers should not restrict their efforts to land sparing.

  Title Detection and Genetic Characterization of Viruses Present in Free-Ranging Snow Leopards Using Next-Generation Sequencing Type Journal Article
  Year 2020 Publication Frontiers in Veterinary Science Abbreviated Journal  
  Volume 7 Issue 645 Pages 1-9  
  Keywords snow leopard, free-ranging, virome, Mongolia, rectal swabs, next-generating sequencing, Panthera unica  
  Abstract Snow leopards inhabit the cold, arid environments of the high

mountains of South and Central Asia. These living conditions likely

affect the abundance and composition of microbes with the capacity to

infect these animals. It is important to investigate the microbes that

snow leopards are exposed to detect infectious disease threats and

define a baseline for future changes that may impact the health of this

endangered felid. In this work, next-generation sequencing is used to

investigate the fecal (and in a few cases serum) virome of seven snow

leopards from the Tost Mountains of Mongolia. The viral species to which

the greatest number of sequences reads showed high similarity was

rotavirus. Excluding one animal with overall very few sequence reads,

four of six animals (67%) displayed evidence of rotavirus infection. A

serum sample of a male and a rectal swab of a female snow leopard

produced sequence reads identical or closely similar to felid

herpesvirus 1, providing the first evidence that this virus infects snow

leopards. In addition, the rectal swab from the same female also

displayed sequence reads most similar to feline papillomavirus 2, which

is the first evidence for this virus infecting snow leopards. The rectal

swabs from all animals also showed evidence for the presence of small

circular DNA viruses, predominantly Circular Rep-Encoding

Single-Stranded (CRESS) DNA viruses and in one case feline anellovirus.

Several of the viruses implicated in the present study could affect the

health of snow leopards. In animals which are under environmental

stress, for example, young dispersing individuals and lactating females,

health issues may be exacerbated by latent virus infections.

  Title A roadmap for conservation in Uttaranchal Type Report
  Year 2006 Publication Abbreviated Journal  
  Volume Issue Pages 1-13  
  Keywords carnivores, conservation, forest, habitat, hunting, landscape, Panthera uncia, poaching, snow leopard, species, tiger, Uncia uncia, ungulates, Uttar Pradesh, 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.

  Title Large carnivores and low diversity of optimal prey: a comparison of the diets of snow leopards Panthera uncia and wolves Canis lupus in Sarychat-Ertash Reserve in Kyrgyzstan Type Journal Article
  Year 2013 Publication Oryx Abbreviated Journal  
  Volume Issue Pages 1-7  
  Keywords Canis lupus, Central Asia, food habits, intraguild competition, Panthera uncia, scat analysis  
  Abstract In the cold and arid mountains of Central Asia, where the diversity and abundance of wild ungulates

are generally low, resource partitioning among coexisting carnivores is probably less distinct than in prey-rich areas. Thus, similar-sized carnivores are likely to compete for food. We compared the summer diets of snow leopards Panthera uncia and wolves Canis lupus in Sarychat-Ertash Reserve in the Tien-Shan mountains of Kyrgyzstan, based on analysis of genetically confirmed scats. Abundances of

the principal prey species, argali Ovis ammon and Siberian ibex Capra sibirica, were estimated from field surveys. The diets consisted of few species, with high interspecific overlap (Pianka’s index50.91). Argali was the predominant prey, with .50% frequency of occurrence in both snow leopard and wolf scats. This was followed by Siberian ibex and marmots Marmota baibacina. Being largely unavailable, remains of livestock were not detected in any of the scats. In the snow leopard diet, proportions of argali and ibex were in

line with the relative availabilities of these animals in the Reserve. This was in contrast to the diet of wolf, where argali occurred according to availability and ibex was significantly underrepresented. The high diet overlap indicates that the two predators might compete for food when the diversity of profitable, large prey is low. Competition may be more intense in winter, when marmots are not available. Hunting of argali and ibex outside the Reserve may be unsustainable and therefore reduce their abundances over time. This will

affect both predators negatively and intensify competition for food. Reduction in ibex populations will directly affect the snow leopard, and the wolf is likely to be indirectly affected as a result of increased snow leopard predation of argali.
