  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 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 Large-scale and fine-grain population structure and genetic diversity of snow leopards (Panthera uncia Schreber, 1776) from the northern and western parts of the range with an emphasis on the Russian population. Type Journal Article
  Year 2021 Publication Conservation Genetics Abbreviated Journal  
  Volume Issue Pages  
  Keywords Snow leopard, Panthera uncia, Microsatellites, Heterozygosity, Population structure, Noninvasive survey, Scat, Subspecies  
  Abstract The snow leopard (Panthera uncia Schreber, 1776) population in Russia and Mongolia is situated at the northern edge of the range, where instability of ecological conditions and of prey availability may serve as prerequisites for demographic instability and, consequently, for reducing the genetic diversity. Moreover, this northern area of the species distribution is connected with the western and central parts by only a few small fragments of potential habitats in the Tian-Shan spurs in China and Kazakhstan. Given this structure of the range, the restriction of gene flow between the northern and other regions of snow leopard distribution can be expected. Under these conditions, data on population genetics would be extremely important for assessment of genetic diversity, population structure and gene flow both at regional and large-scale level. To investigate large-scale and fine-grain population structure and levels of genetic diversity we analyzed 108 snow leopards identified from noninvasively collected scat samples from Russia and Mongolia (the northern part of the range) as well as from Kyrgyzstan and Tajikistan (the western part of the range) using panel of eight polymorphic microsatellites. We found low to moderate levels of genetic diversity in the studied populations. Among local habitats, the highest heterozygosity and allelic richness were recorded in Kyrgyzstan (He = 0.66 ± 0.03, Ho = 0.70 ± 0.04, Ar = 3.17) whereas the lowest diversity was found in a periphery subpopulation in Buryatia Republic of Russia (He = 0.41 ± 0.12, Ho = 0.29 ± 0.05, Ar = 2.33). In general, snow leopards from the western range exhibit greater genetic diversity (He = 0.68 ± 0.04, Ho = 0.66 ± 0.03, Ar = 4.95) compared to those from the northern range (He = 0.60 ± 0.06, Ho = 0.49 ± 0.02, Ar = 4.45). In addition, we have identified signs of fragmentation in the northern habitat, which have led to significant genetic divergence between subpopulations in Russia. Multiple analyses of genetic structure support considerable genetic differentiation between the northern and western range parts, which may testify to subspecies subdivision of snow leopards from these regions. The observed patterns of genetic structure are evidence for delineation of several management units within the studied populations, requiring individual approaches for conservation initiatives, particularly related to translocation events. The causes for the revealed patterns of genetic structure and levels of genetic diversity are discussed.

  Title Change in snow leopard predation on livestock after revival of wild prey in the Trans-Himalaya Type Journal Article
  Year 2020 Publication Wildlife Biology Abbreviated Journal  
  Volume Issue Pages 1-11  
  Keywords arid ecosystems, diet analysis, human-wildlife conflict, Panthera, predator, rangeland  
  Abstract Human–wildlife conflict arising from livestock-losses to large carnivores is an important challenge faced by conservation. Theory of prey–predator interactions suggests that revival of wild prey populations can reduce predator’s dependence on livestock in multiple-use landscapes. We explore whether 10-years of conservation efforts to revive wild prey could reduce snow leopard’s Panthera uncia consumption of livestock in the coupled human-and-natural Trans-Himalayan ecosystem of northern India. Starting in 2001, concerted conservation efforts at one site (intervention) attempted recovery of wild- prey populations by creating livestock-free reserves, accompanied with other incentives (e.g. insurance, vigilant herding). Another site, 50km away, was monitored as status quo without any interventions. Prey remains in snow leopard scats were examined periodically at five-year intervals between 2002 and 2012 to determine any temporal shift in diet at both sites to evaluate the effectiveness of conservation interventions. Consumption of livestock increased at the status quo site, while it decreased at the intervention-site. At the intervention-site, livestock-consumption reduced during 2002–2007 (by 17%, p = 0.06); this effect was sustained during the next five-year interval, and it was accompanied by a persistent increase in wild prey populations. Here we also noted increased predator populations, likely due to immigration into the study area. Despite the increase in the predator population, there was no increase in livestock-consumption. In contrast, under status quo, dependence on livestock increased during both five-year intervals (by 7%, p=0.08, and by 16%, p=0.01, respectively). These contrasts between the trajectories of the two sites suggest that livestock-loss can potentially be reduced through the revival of wild prey. Further, accommodating counter-factual scenarios may be an important step to infer whether conservation efforts achieve their targets, or not.

  Title First camera-trap record of the snow leopard Panthera uncia in Gaurishankar Conservation Area, Nepal Type Journal Article
  Year 2020 Publication Oryx Abbreviated Journal  
  Volume Issue Pages 1-4  
  Keywords Camera trap, corridor, Gaurishankar Conser- vation Area, Nepal, Panthera uncia, prey abundance, transboundary, snow leopard  
  Abstract The snow leopard Panthera uncia is the flagship species of the high mountains of the Himalayas. There is po- tentially continuous habitat for the snow leopard along the northern border of Nepal, but there is a gap in information about the snow leopard in Gaurishankar Conservation Area. Previous spatial analysis has suggested that the Lamabagar area in this Conservation Area could serve as a transbound- ary corridor for snow leopards, and that the area may con- nect local populations, creating a metapopulation. However, there has been no visual confirmation of the species in Lamabagar. We set !! infrared camera traps for " months in Lapchi Village of Gaurishankar Conservation Area, where blue sheep Pseudois nayaur, musk deer Moschus leucogaster and Himalayan tahr Hemitragus jemlahicus, all snow leopard prey species, had been observed. In November #$!% at &,!$$ m, ' km south-west of Lapchi Village, one camera recorded three images of a snow leopard, the first photographic evidence of the species in the Conservation Area. Sixteen other species of mammals were also recorded. Camera-trap records and sightings indicated a high abun- dance of Himalayan tahr, blue sheep and musk deer. Lapchi Village may be a potentially important corridor for snow leopard movement between the east and west of Nepal and northwards to Quomolongma National Park in China. However, plans for development in the region present in- creasing threats to this corridor. We recommend develop- ment of a transboundary conservation strategy for snow leopard conservation in this region, with participation of Nepal, China and international agencies.

  Title Meta-replication, sampling bias, and multi-scale model selection: A case study on snow leopard (Panthera uncia) in western China. Type Journal Article
  Year 2020 Publication Ecology and Evolution Abbreviated Journal  
  Volume Issue Pages 1-27  
  Keywords MaxEnt, meta-replication, multi-scale, Panthera uncia, sampling bias, scale selection, snow leopard, species distribution model  
  Abstract Replicated multiple scale species distribution models (SDMs)

have become increasingly important to identify the correct variables

determining species distribution and their influences on ecological

responses. This study explores multi-scale habitat relationships of the

snow leopard (Panthera uncia) in two study areas on the Qinghai–Tibetan

Plateau of western China. Our primary objectives were to evaluate the

degree to which snow leopard habitat relationships, expressed by

predictors, scales of response, and magnitude of effects, were

consistent across study areas or locally landcape-specific. We coupled

univariate scale optimization and the maximum entropy algorithm to

produce multivariate SDMs, inferring the relative suitability for the

species by ensembling top performing models. We optimized the SDMs based

on average omission rate across the top models and ensembles’ overlap

with a simulated reference model. Comparison of SDMs in the two study

areas highlighted landscape-specific responses to limiting factors.

These were dependent on the effects of the hydrological network,

anthropogenic features, topographic complexity, and the heterogeneity of

the landcover patch mosaic. Overall, even accounting for specific local

differences, we found general landscape attributes associated with snow

leopard ecological requirements, consisting of a positive association

with uplands and ridges, aggregated low-contrast landscapes, and large

extents of grassy and herbaceous vegetation. As a means to evaluate the

performance of two bias correction methods, we explored their effects on

three datasets showing a range of bias intensities. The performance of

corrections depends on the bias intensity; however, density kernels

offered a reliable correction strategy under all circumstances. This

study reveals the multi-scale response of snow leopards to environmental

attributes and confirms the role of meta-replicated study designs for

the identification of spatially varying limiting factors. Furthermore,

this study makes important contributions to the ongoing discussion about

the best approaches for sampling bias correction.

  Title Multiple factors influence local perceptions of snow leopards and Himalayan wolves in the central Himalayas, Nepal. Type Journal Article
  Year 2020 Publication PeerJ Abbreviated Journal  
  Volume Issue Pages 1-18  
  Keywords Panthera uncia, Canis lupus chanco, Perceptions, Large carnivores, Trans-Himalayas  
  Abstract An understanding of local perceptions of carnivores is

important for conservation and management planning. In the central

Himalayas, Nepal, we interviewed 428 individuals from 85 settlements

using a semi-structured questionnaire to quantitatively assess local

perceptions and tolerance of snow leopards and wolves. We used

generalized linear mixed effect models to assess influential factors,

and found that tolerance of snow leopards was much higher than of

wolves. Interestingly, having experienced livestock losses had a minor

impact on perceptions of the carnivores. Occupation of the respondents

had a strong effect on perceptions of snow leopards but not of wolves.

Literacy and age had weak impacts on snow leopard perceptions, but the

interaction among these terms showed a marked effect, that is, being

illiterate had a more marked negative impact among older respondents.

Among the various factors affecting perceptions of wolves, numbers of

livestock owned and gender were the most important predictors. People

with larger livestock herds were more negative towards wolves. In terms

of gender, males were more positive to wolves than females, but no such

pattern was observed for snow leopards. People’s negative perceptions

towards wolves were also related to the remoteness of the villages.

Factors affecting people’s perceptions could not be generalized for the

two species, and thus need to be addressed separately. We suggest future

conservation projects and programs should prioritize remote settlements.

  Title Snow leopard Panthera uncia predation on livestock and wild prey in a mountain valley in northern Nepal: implications for conservation management Type Journal Article
  Year 2012 Publication Wildlife Biology Abbreviated Journal  
  Volume 18 Issue 10.2981/11-049 Pages 131-141  
  Keywords bharal, blue sheep, diet, genetic sampling, naur, Panthera uncia, predation, Pseudois nayaur, scat analysis, snow leopard, wildlife conflict  
  Abstract The globally endangered snow leopard Panthera uncia is sparsely distributed throughout the rugged mountains in Asia.

Its habit of preying on livestock poses a main challenge to management. In the remote Phu valley in northern Nepal, we

obtained reliable information on livestock losses and estimated predator abundance and diet composition from DNA

analysis and prey remains in scats. The annual diet consisted of 42%livestock. Among the wild prey, bharal (blue sheep/

naur) Pseudois nayaur was by far the most common species (92%). Two independent abundance estimates suggested that

there were six snow leopards in the valley during the course of our study. On average, each snow leopard killed about one

livestock individual and two bharal permonth. Predation loss of livestock estimated fromprey remains in scats was 3.9%,

which was in concordance with village records (4.0%). From a total count of bharal, the only large natural prey in the area

and occurring at a density of 8.4 animals/km2 or about half the density of livestock, snow leopards were estimated to

harvest 15.1% of the population annually. This predation rate approaches the natural, inherent recruitment rate of this

species; in Phu the proportion of kids was estimated at 18.4%. High livestock losses have created a hostile attitude against

the snow leopard and mitigation measures are needed. Among innovative management schemes now being implemented

throughout the species’ range, compensation and insurance programmes coupled with other incentive measures are

encouraged, rather than measures to reduce the snow leopard’s access to livestock. In areas like the Phu valley, where the

natural prey base consists mainly of one ungulate species that is already heavily preyed upon, the latter approach, if

implemented, will lead to increased predation on this prey, which over time may suppress numbers of both prey and

predator.

  Title People, predators and perceptions: patterns of livestock depredation by snow leopards and wolves Type Journal Article
  Year 2013 Publication Journal of Applied Ecology Abbreviated Journal  
  Volume 50 Issue Pages 550-560  
  Keywords Canis lupus, Capra ibex, human–wildlife conflict, large carnivores, Panthera uncia, Pseudois nayaur, trans-Himalaya  
  Abstract 1. Livestock depredation by large carnivores is an important conservation and economic concern

and conservation management would benefit from a better understanding of spatial variation

and underlying causes of depredation events. Focusing on the endangered snow leopard

Panthera uncia and the wolf Canis lupus, we identify the ecological factors that predispose

areas within a landscape to livestock depredation. We also examine the potential mismatch

between reality and human perceptions of livestock depredation by these carnivores whose

survival is threatened due to persecution by pastoralists.

2. We assessed the distribution of the snow leopard, wolf and wild ungulate prey through field

surveys in the 4000 km2 Upper Spiti Landscape of trans-Himalayan India. We interviewed local

people in all 25 villages to assess the distribution of livestock and peoples’ perceptions of the risk

to livestock from these carnivores. We monitored village-level livestock mortality over a 2-year

period to assess the actual level of livestock depredation. We quantified several possibly influential

independent variables that together captured variation in topography, carnivore abundance

and abundance and other attributes of livestock. We identified the key variables influencing livestock

depredation using multiple logistic regressions and hierarchical partitioning.

3. Our results revealed notable differences in livestock selectivity and ecological correlates of

livestock depredation – both perceived and actual – by snow leopards and wolves. Stocking

density of large-bodied free-ranging livestock (yaks and horses) best explained people’s threat

perception of livestock depredation by snow leopards, while actual livestock depredation was

explained by the relative abundance of snow leopards and wild prey. In the case of wolves,

peoples’ perception was best explained by abundance of wolves, while actual depredation by

wolves was explained by habitat structure.

4. Synthesis and applications. Our results show that (i) human perceptions can be at odds

with actual patterns of livestock depredation, (ii) increases in wild prey populations will intensify

livestock depredation by snow leopards, and prey recovery programmes must be accompanied

by measures to protect livestock, (iii) compensation or insurance programmes should

target large-bodied livestock in snow leopard habitats and (iv) sustained awareness

programmes are much needed, especially for the wolf.

  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.
