  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 (down) 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 (down) 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 In the shadows of snow leopards and the Himalayas: density and habitat selection of blue sheep in Manang, Nepal Type Journal Article
  Year (down) 2020 Publication Ecology and Evolution Abbreviated Journal  
  Volume 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 Research trends and management options in human-snow leopard conflict Type Journal Article
  Year (down) 2020 Publication Biological Conservation Abbreviated Journal  
  Volume 242 Issue 108413 Pages 1-10  
  Keywords Snow leopards, Systematic review, Compensation, Co-existence, Livestock, Human-wildlife conflict, Mitigation  
  Abstract Conservation of the snow leopard (Panthera uncia) is challenging because of its threatened status and increase in human-snow leopard conflict (HSC). The area of occupancy of the snow leopard comprises mountainous regions of Asia that are confronted with various environmental pressures including climate change. HSCs have increased with a burgeoning human population and economic activities that enhance competition between human and snow leopard or its preys. Here we systematically review the peer-reviewed literature from 1994 to 2018 in Web of Science, Google Scholar, Science Direct and PubMed (30 articles), to evaluate the current state of scholarship about HSCs and their management. We determine: 1) the spatio-temporal distribution of relevant researches; 2) the methodologies to assess HSCs; 3) and evaluate existing interventions for conflict management; and 4) the potential options for HSC management. The aim of the current study is thus to identify key research gaps and future research requirements. Of the articles in this review, 60% evaluated the mitigation of HSCs, while only 37% provided actionable and decisive results. Compensation programs and livestock management strategies had high success rates for mitigating HSCs through direct or community-managed interventions. Further research is required to evaluate the efficacy of existing HSC mitigation strategies, many of which, while recommended, lack proper support. In spite of the progress made in HSC studies, research is needed to examine ecological and sociocultural context of HSCs. We suggest future work focus on rangeland management for HSC mitigation, thus ultimately fostering a co-existence between human and snow leopard.

  Title Sampling bias in snow leopard population estimation studies Type Journal Article
  Year (down) 2019 Publication Population Eccology Abbreviated Journal  
  Volume Issue Pages 1-9  
  Keywords camera trap, Central Asia, Himalaya, meta-analysis, monitoring, Panthera uncia, population ecology  
  Abstract Accurate assessments of the status of threatened species and their conservation

planning require reliable estimation of their global populations and robust monitoring

of local population trends. We assessed the adequacy and suitability of studies

in reliably estimating the global snow leopard (Panthera uncia) population. We

compiled a dataset of all the peer-reviewed published literature on snow leopard

population estimation. Metadata analysis showed estimates of snow leopard density

to be a negative exponential function of area, suggesting that study areas have generally

been too small for accurate density estimation, and sampling has often been

biased towards the best habitats. Published studies are restricted to six of the

12 range countries, covering only 0.3�0.9% of the presumed global range of the

species. Re-sampling of camera trap data from a relatively large study site

(c.1684 km2) showed that small-sized study areas together with a bias towards

good quality habitats in existing studies may have overestimated densities by up to

five times. We conclude that current information is biased and inadequate for generating

a reliable global population estimate of snow leopards. To develop a rigorous

and useful baseline and to avoid pitfalls, there is an urgent need for

(a) refinement of sampling and analytical protocols for population estimation of

snow leopards (b) agreement and coordinated use of standardized sampling protocols

amongst researchers and governments across the range, and (c) sampling

larger and under-represented areas of the snow leopard's global range.

  Title Estimating snow leopard density using fecal DNA in a large landscape in north-central Nepal Type Journal Article
  Year (down) 2019 Publication Global Ecology and Conservation Abbreviated Journal  
  Volume Issue 17 Pages 1-8  
  Keywords Panthera uncia, Density, Annapurna-Manaslu landscape, Noninvasive, Spatial scale  
  Abstract Although abundance estimates have a strong bearing on the conservation status of a

species, less than 2% of the global snow leopard distribution range has been sampled

systematically, mostly in small survey areas. In order to estimate snow leopard density

across a large landscape, we collected 347 putative snow leopard scats from 246 transects

(490 km) in twenty-six 5  5km sized sampling grid cells within 4393 km2 in Annapurna-

Manaslu, Nepal. From 182 confirmed snow leopard scats, 81 were identified as belonging

to 34 individuals; the remaining were discarded for their low (<0.625) quality index. Using

maximum likelihood based spatial capture recapture analysis, we developed candidate

model sets to test effects of various covariates on density and detection of scats on transects.

The best models described the variation in density as a quadratic function of

elevation and detection as a linear function of topography. The average density estimate of

snow leopards for the area of interest within Nepal was 0.95 (SE 0.19) animals per 100 km2

(0.66e1.41 95% CL) with predicted densities varying between 0.1 and 1.9 in different parts,

thus highlighting the heterogeneity in densities as a function of habitat types. Our density

estimate was low compared to previous estimates from smaller study areas. Probably,

estimates from some of these areas were inflated due to locally high abundances in overlap

zones (hotspots) of neighboring individuals, whose territories probably range far beyond

study area borders. Our results highlight the need for a large-scale approach in snow

leopard monitoring, and we recommend that methodological problems related to spatial

scale are taken into account in future snow leopard research.

  Title Livestock depredation by snow leopard and Tibetan wolf: Implications for herders&#65533; livelihoods in Wangchuck Centennial National Park, Bhutan Type Journal Article
  Year (down) 2019 Publication Springer Open Abbreviated Journal  
  Volume Issue 9:1 Pages 1-10  
  Keywords Wildlife-livestock conflicts, Endangered predators, Protected area, Income loss  
  Abstract Human-wildlife conflict (HWC) is a serious problem in many parts of the world, and Bhutan&#65533;s Wangchuck Centennial

National Park (WCNP) is no exception. Located in the remote alpine areas of the eastern Himalaya, wildlife species

such as snow leopard (SL) and Tibetan wolf (TW) are reported to kill livestock in many parts of the Park. Such

depredation is believed to have affected the livelihoods of high-altitude herding communities, resulting in conflicts

between them. This study provides analysis on the extent of livestock depredation by wildlife predators such as SL

and TW and examines its implications for the livelihoods of herding communities of Choekhortoe and Dhur regions

of WCNP. Using semi-structured questionnaires, all herders (n = 38) in the study area were interviewed. The questions

pertained to livestock population, frequency of depredation and income lost due to depredation in the last five years

from 2012 to 2016. This study recorded 2,815 livestock heads in the study area, with an average herd size of 74.1 stock.

The average herd size holding showed a decreasing trend over the years, and one of the reasons cited by the herders

is depredation by SL and TW and other predators. This loss equated to an average annual financial loss equivalent to

10.2% (US$837) of their total per capita cash income. Such losses have resulted in negative impacts on herders&#65533;

livelihood; e.g. six herders (2012-2016) even stopped rearing livestock and resorted to an alternate source of cash

income. The livestock intensification programmes, including pasture improvement through allowing controlled

burning, and financial compensation, may be some potential short-term solutions to reduce conflict between herders

and predators. Issuing permits for cordyceps (Ophiocordyceps sinensis) collection only to the herders and instilling the

sense of stewardship to highland herders may be one of the long-term solutions.

  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 (down) 2019 Publication Abbreviated Journal  
  Volume 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&#65533;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 Improving our conservation genetic toolkit: ddRAD-seq for SNPs in snow leopards Type Journal Article
  Year (down) 2019 Publication Conservation Genetic Resource Abbreviated Journal  
  Volume Issue Pages  
  Keywords  
  Abstract Snow leopards (Panthera uncia) are an enigmatic, high-altitude species whose challenging habitat, low population densities

and patchy distribution have presented challenges for scientists studying its biology, population structure, and genetics.

Molecular scatology brings a new hope for conservation efforts by providing valuable insights about snow leopards, including

their distribution, population densities, connectivity, habitat use, and population structure for assigning conservation units.

However, traditional amplification of microsatellites from non-invasive sources of DNA are accompanied by significant

genotyping errors due to low DNA yield and poor quality. These errors can lead to incorrect inferences in the number of

individuals and estimates of genetic diversity. Next generation technologies have revolutionized the depth of information

we can get from a species' genome. Here we used double digest restriction-site associated DNA sequencing (ddRAD-seq),

a well-established technique for studying non-model organisms, to develop a reference sequence library for snow leopards

using blood samples from five Mongolian individuals. Our final data set reveals 4504 loci with a median size range of 221 bp.

We identified 697 SNPs and low nucleotide diversity (0.00032) within these loci. However, the probability that two random

individuals will share identical genotypes is about 10-168. We developed probes for DNA capture using this sequence library

which can now be used for genotyping individuals from scat samples. Genetic data from ddRAD-seq will be invaluable for

conducting population and landscape scale studies that can inform snow leopard conservation strategies.

  Title Snow leopard stewardship in mitigating human-wildlife conflict in Hemis National Park, Ladakh, India Type Journal Article
  Year (down) 2019 Publication Human Dimensions of Wildlife Abbreviated Journal  
  Volume Issue Pages 1-5  
  Keywords Snow leopard; human-wildlife conflict; ecotourism; livelihood; India  
  Abstract Among large predators, snow leopards (Panthera uncia) and co-predators (e.g., wolves

Canis lupus, lynx Lynx lynx) often cause economic losses, engendering animosity from

local communities in the mountain ecosystem across south and central Asia (Din et al.,

2017; Jackson & Lama, 2016; Maheshwari, Takpa, Kujur, & Shawl, 2010; Schaller, 2012).

These economic losses range from around US $50 to nearly $300 per household,

a significant sum given per capita annual incomes of $250 – $400 (Jackson & Wangchuk,

2004; Mishra, 1997). Recent efforts such as improved livestock husbandry practices

(predator-proof livestock corrals – closed night shelters with covered roof with wiremesh

and a closely fitting iron or wooden door that can be securely locked at night) and

community-based ecotourism (e.g., home stays, guides, porters, pack animals, campsites)

are providing alternative livelihood opportunities and mitigating large carnivores – human

conflict in the snow leopard habitats (Hanson, Schutgens, & Baral, 2018; Jackson, 2015;

Jackson & Lama, 2016; Vannelli, Hampton, Namgail, & Black, 2019). Snow leopard-based

ecotourism provides an opportunity to secure livelihoods and reduce poverty of the

communities living in ecotourism sites across Ladakh (Chandola, 2012; Jackson, 2015).

To understand the role of snow leopard-based ecotourism in uplifting the financial profile

of local communities, mitigating large carnivore – human conflict and eventually changing

attitudes towards large carnivores in Hemis National Park, Ladakh, India, we compared

the estimated financial gains of a snow leopard-based ecotourism to stated livestock

predation losses by snow leopards and wolves.
