Title The timing of breeding and independence for snow leopard females and their cubs. Type Journal Article
Year 2020 Publication (down) 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 Conservation importance of the strategic, centrally located snow leopard population in the western Himalayas, India: a genetic perspective Type Journal Article
Year 2022 Publication (down) Mammalian Biology Abbreviated Journal
Volume Issue Pages 13
Keywords Panthera uncia, Western Himalayas, Microsatellite, Genetic diversity, Functional connectivity
Abstract The snow leopard population in Union Territory of Ladakh (UTL), India is at the centre of five out of eight mountain ranges within the species' habitat in the high-mountain Asia. Its strategic location is of immense conservation significance to maintain genetic connectivity and metapopulation dynamics of snow leopards (Panthera uncia). Therefore, we provide the first estimates of the snow leopard's individual-based spatial genetic characteristics from UTL. Multi-locus genotyping (n = 14 loci) of individuals (n = 19) revealed moderate genetic diversity in the population (mean number of alleles = 5.86 ± 0.55, observed heterozygosity = 0.48 ± 0.05, expected heterozygosity = 0.65 ± 0.03, allelic richness = 2.65 ± 0.15). We did not observe any evidence of population structuring (using STRUCTURE and Factorial Correspondence Analysis) or isolation by distance. However, the clustering approach based on genetic distance (Nei's standard distance and Cavalli-Sforza and Edwards distance) and subsequent discriminant analysis of principal components (DAPC) revealed three sub-clusters of related individuals within the study population without any spatial correlates. We observed 1.2% first-order relatives, suggesting sufficient dispersal and panmixia in the UTL population. We observed high fixation index (FIS = 0.26 ± 0.05; 0.17 ± 0.03 upon removing loci with null alleles) and presence of individuals from genetically divergent populations in UTL. Hence, the high positive FIS value could be attributed to both Wahlund effect and inbreeding. Prioritization and effective conservation planning of the UTL population as a source would benefit the global snow leopard population by (i) maintaining connectivity between the Himalayas and the central Asian mountain ranges, and (ii) providing refuge during future climate change-related range contraction.

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 (down) Journal of Zoology London Abbreviated Journal
Volume 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 Common and snow leopards share prey, but not habitats: competition avoidance by large predators Type Journal Article
Year 2013 Publication (down) Journal of Zoology Abbreviated Journal
Volume 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 Feline panleukopena virus and subsequent canine-distemper virus infection in two snow leopards (Panthera uncia) Type Journal Article
Year 1989 Publication (down) Journal of Zoo and Wildlife Medicine Abbreviated Journal
Volume 20 Issue 3 Pages 273-281
Keywords diagnosis; fecal; Fpv; leukemia; panleukopenia; panthera uncia; snow leopard; therapy; vaccination; veterinary; Virus; zoo
Abstract Two adult snow leopards (Panthera uncia), male and female, both with vaccinations current, became infected with feline panleukopenia virus (FPV) at the Blank Park Zoo, Des Moines, Iowa, in late 1988. Clinical signs included weakness, hemorrhagic feces, fever, seizures, and nasal discharge. Blood analysis revealed severe lymphopenia and mild anemia. A positive enzyme-linked immunosorbent assay (ELISA) test for FPV on fecal contents from the male leopard confirmed the diagnosis. In spite of intensive therapy, both animals died. Necropsy of the female, which survived for 1 wk after onset of signs, revealed intestinal crypt necrosis, pulmonary consolidation, necrotizing laryngitis, and diffuse lymphoid depletion. The male leopard, which lived 3 wk after onset of illness, had similar enteric and lymphoid lesions. In addition, there was a severe interstitial pneumonia, with syncytial cells containing eosinophilic intracytoplasmic inclusion bodies. Ultrastructural characteristics of these inclusions featured tubular structures consistent with a paramyxovirus. Although repeated virus isolation attempts from the affected lung were negative, polyclonal and monoclonal fluorescent antibody tests were strongly positive for canine distemper virus (CDV). Frozen paired sera from each leopard demonstrated very high acute and convalescing titers to FPV; both animals also seroconverted to CDV, with titers in the male leopard higher than those in the female. Additional tests for toxoplasmosis, feline infectious peritonitis, feline rhinotracheitis, feline calicivirus, feline leukemia, canine parainfluenza, and bovine respiratory syncytial virus were all negative. The neurologic signs present in these leopards remained unexplained, but may have been attributable to CDV infection. A feral cat trapped on zoo property had feces positive for FPV by ELISA. Although the specific contributions of FPV and CDV toward the development of this case are unknown, it is likely that initial FPV-induced immunosuppression allowed the subsequent development of CDV in these snow leopards. The likelihood that initial FPV infection came from feral cats underscores the importance of feral animal control on zoo premises.

Title Seasonal pattern in group size and population composition of blue sheep in Manang, Nepal Type Journal Article
Year 1996 Publication (down) Journal of Wildlife Management Abbreviated Journal
Volume 60 Issue 4 Pages 797-801
Keywords prey; snow leopard; panthera uncia; Nepal; annapurna conservation area; predator; blue; sheep; browse; Panthera-uncia; panthera; uncia; Annapurna-Conservation-Area; annapurna; conservation; area; 650
Abstract Blue sheep (Pseudois nayaur) are the principal prey of the endangered snow leopard (Panthera uncia) in the Himalayas and adjacent ranges. We studied group size and population composition of blue sheep in Manang District, Annapurna Conservation Area, Nepal. Overall mean group size was 15.6 (SE = 1.3), but it varied seasonally (P lt 0.001), with significantly smaller groups in winter than in other seasons. Mixed groups were most numerous in all seasons, and there was no evidence of sexual segregation. Yearling sex ratio (93.7 M:100 F) did not vary seasonally, nor did the ratio deviate from parity. Adult sex ratio showed a seasonal pattern favoring males post-parturition but female-biased during the rut and pre-parturition. Seasonal variation in sex-specific mortality is offered as a plausible explanation for the observed pattern in adult sex ratio.

Title Mycotic pneumonia and meningoencephalitis due to Aspergillus terreus in a neonatal snow leopard (Panthera uncia) Type Miscellaneous
Year 1985 Publication (down) Journal of Wildlife Diseases Abbreviated Journal
Volume 21 Issue Pages 301-305
Keywords Aspergillus; hand rearing; Meningoencephalitis; panthera uncia; Pneumonia; snow leopard; zoological
Abstract On 14 May 1983, two female snow leopard (Panthera uncia) cubs were born in the Kansas City Zoological Gardens to a primiparous female. The female showed little interest in the cubs, one of which had a body temperature of 30 C, so they were removed for hand-rearing. On 15 May, one cub was less active, and did not nurse as well as its littermate.

Title Cats, canines, and coexistence: dietary differentiation between the sympatric Snow Leopard and Grey Wolf in the western landscape of Nepal Himalaya Type Journal Article
Year 2019 Publication (down) Journal of Threatened Taxa Abbreviated Journal
Volume 11 Issue 7 Pages 13815-13821
Keywords Canis lupus, dietary pattern, dietary overlap, livestock, Naur, negative interaction, Panthera uncia, scat analysis, sympatry
Abstract Understanding the dietary habits of sympatric apex carnivores advances our knowledge of ecological processes and aids their conservation. We compared the diets of the sympatric Snow Leopard Panthera uncia and Grey Wolf Canis lupus using standard micro-histological analyses of scats collected from the western complex of Nepal Himalaya. Our study revealed one of the highest recorded contributions of livestock to the diet of top predators (55% for Grey Wolf and 39% for Snow Leopard) and high dietary overlap (0.82) indicating potential exploitative or interference competition. Their diet composition, however, varied significantly based on their consumption of wild and domestic prey. Limitation in data precludes predicting direction and outcome of inter-specific interactions between these predators. Our findings suggest a high rate of negative interaction with humans in the region and plausibly retaliatory killings of these imperilled predators. To ensure the sustained survival of these two apex carnivores, conservation measures should enhance populations of their wild prey species while reducing livestock losses of the local community through preventive and mitigative interventions.

Title How Snow Leopards Share the Same Landscape with Tibetan Agro-pastoral Communities in the Chinese Himalayas Type Journal Article
Year 2022 Publication (down) Journal of Resources and Ecology Abbreviated Journal
Volume 13 Issue 3 Pages 483-500
Keywords habitat use; landscape ecology; occupancy model; Qomolangma; Panthera uncia
Abstract The snow leopard (Panthera uncia) inhabits a human-altered alpine landscape and is often tolerated by residents in regions where the dominant religion is Tibetan Buddhism, including in Qomolangma NNR on the northern side of the Chinese Himalayas. Despite these positive attitudes, many decades of rapid economic development and population growth can cause increasing disturbance to the snow leopards, altering their habitat use patterns and ultimately impacting their conservation. We adopted a dynamic landscape ecology perspective and used multi-scale technique and occupancy model to better understand snow leopard habitat use and coexistence with humans in an 825 km2 communal landscape. We ranked eight hypothetical models containing potential natural and anthropogenic drivers of habitat use and compared them between summer and winter seasons within a year. HABITAT was the optimal model in winter, whereas ANTHROPOGENIC INFLUENCE was the top ranking in summer (AICcw≤2). Overall, model performance was better in the winter than in the summer, suggesting that perhaps some latent summer covariates were not measured. Among the individual variables, terrain ruggedness strongly affected snow leopard habitat use in the winter, but not in the summer. Univariate modeling suggested snow leopards prefer to use rugged land in winter with a broad scale (4000 m focal radius) but with a lesser scale in summer (30 m); Snow leopards preferred habitat with a slope of 22° at a scale of 1000 m throughout both seasons, which is possibly correlated with prey occurrence. Furthermore, all covariates mentioned above showed inextricable ties with human activities (presence of settlements and grazing intensity). Our findings show that multiple sources of anthropogenic activity have complex connections with snow leopard habitat use, even under low human density when anthropogenic activities are sparsely distributed across a vast landscape. This study is also valuable for habitat use research in the future, especially regarding covariate selection for finite sample sizes in inaccessible terrain.
