  Title Status of the mountain ungulate prey of the Endangered snow leopard Panthera uncia in the Tost Local Protected Area, South Gobi, Mongolia Type Journal Article
  Year 2015 Publication (down) Oryx Abbreviated Journal  
  Volume Issue Pages 1-6  
  Keywords Argali, Central Asia, double-observer survey, ibex, Panthera uncia, snow leopard, ungulate prey  
  Abstract The availability of wild prey is a critical predictor of carnivore density. However, few conservation pro- grammes have focused on the estimation and monitoring of wild ungulate populations and their trends, especially in the remote mountains of Central Asia. We conducted double-observer surveys to estimate the populations of ibex Capra sibirica and argali Ovis ammon in the mountain- ous regions of Tost Local Protected Area, South Gobi prov- ince, Mongolia, which is being considered for designation as a Nature Reserve. We also conducted demographic surveys of the more abundant ibex to examine their sex-ratio and the survival of young during –. The estimated ibex population remained stable in  and  and the es- timated argali population increased from  in  to  in . The biomass of wild ungulates was c. % that of live- stock. Mortality in young ibex appeared to increase after weaning, at the age of  months. We estimated the popula- tion of wild ungulates was sufficient to support – adult snow leopards Panthera uncia. The adult snow leopard population in our study area during –, estimated independently using camera-trap-based mark–recapture methods, was –. Based on our results we identify the Tost Local Protected Area as an important habitat for the conservation of these ungulates and their predator, the Endangered snow leopard, and recommend elevation of its status to a Nature Reserve.

  Title On the high trail: examining determinants of site use by the Endangered snow leopard Panthera uncia in Qilianshan, China Type Journal Article
  Year 2015 Publication (down) Oryx Abbreviated Journal  
  Volume Issue Fauna & Flora International Pages 1-8  
  Keywords Camera Trap, China, Detection Probability, Occupancy Modelling, Panthera Uncia, Site use, Snow Leopard  
  Abstract Abstract There is a need for simple and robust techniques for assessment and monitoring of populations of the Endangered snow leopard Panthera uncia to inform the de- velopment of action plans for snow leopard conservation. We explored the use of occupancy modelling to evaluate the influence of environmental and anthropogenic features on snow leopard site-use patterns. We conducted a camera trap survey across  km in Gansu Province, China, and used data from  camera traps to estimate probabilities of site use and detection using the single season occupancy model. We assessed the influence of three covariates on site use by snow leopards: elevation, the presence of blue sheep Pseudois nayaur and the presence of human disturb- ance (distance to roads). We recorded  captures of snow leopards over , trap-days, representing a mean capture success of . captures per  trap-days. Elevation had the strongest influence on site use, with the probability of site use increasing with altitude, whereas the influence of presence of prey and distance to roads was relatively weak. Our findings indicate the need for practical and robust tech- niques to appraise determinants of site use by snow leo- pards, especially in the context of the limited resources available for such work.

  Title Why should a grazer browse? Livestock impact on winter resource use by bharal Pseudois nayaur Type Journal Article

  Abstract Many mammalian herbivores show a temporal diet variation between graminoid-dominated and browse dominated diets. We determined the causes of such a diet shift and its implications for conservation of a medium sized ungulate-the bharal Pseudois nayaur. Past studies show that the bharal diet is dominated by graminoids (>80%) during summer, but the contribution of graminoids declines to about 50% in winter. We tested the predictions generated by two alternative hypotheses explaining the decline: low graminoid availability during winter causes bharal to include browse in their diet; bharal include browse, with relatively higher nutritional quality, in their diet to compensate for the poor quality of graminoids during winter. We measured winter graminoid availability in areas with no livestock grazing, areas with relatively moderate livestock grazing, and those with intense livestock grazing pressures. The chemical composition of plants contributing to the bharal diet was analysed. The bharal diet was quantiWed through signs of feeding on vegetation at feeding locations. Population structures of bharal populations were recorded using a total count method. Graminoid availability was highest in areas without livestock grazing, followed by areas with moderate and intense livestock grazing. The bharal diet was dominated by graminoids (73%) in areas with highest graminoid availability. Graminoid contribution to the bharal diet declined monotonically (50, 36%) with a decline in graminoid availability. Bharal young to female ratio was 3 times higher in areas with high graminoid availability than areas with low graminoid availability. The composition of the bharal winter diet was governed predominantly by the availability of graminoids in the rangelands. Our results suggest that bharal include more browse in their diet during winter due to competition from livestock for graminoids. Since livestock grazing reduces graminoid availability, creation of livestock-free areas is necessary for the conservation of grazing species such as the bharal and its predators including the endangered snow leopard in the Trans-Himalaya.

  Title Understanding population baselines: status of mountain ungulate populations in the Central Tien Shan Mountains, Kyrgyzstan Type Journal Article
  Year 2020 Publication (down) Mammalia Abbreviated Journal  
  Volume Issue Pages 1-8  
  Keywords conservation; human-use landscapes; hunting concession; mountain ungulates; population baselines; protected areas.  
  Abstract We assessed the density of argali (Ovis ammon) and ibex

(Capra sibirica) in Sarychat-Ertash Nature Reserve and its neighbouring

Koiluu valley. Sarychat is a protected area, while Koiluu is a human-use

landscape which is a partly licenced hunting concession for mountain

ungulates and has several livestock herders and their permanent

residential structures. Population monitoring of mountain ungulates can

help in setting measurable conservation targets such as appropriate

trophy hunting quotas and to assess habitat suitability for predators

like snow leopards (Panthera uncia). We employed the double-observer

method to survey 573 km2 of mountain ungulate habitat inside Sarychat

and 407 km2 inside Koiluu. The estimated densities of ibex and argali in

Sarychat were 2.26 (95% CI 1.47–3.52) individuals km-2 and 1.54 (95% CI

1.01–2.20) individuals km-2, respectively. Total ungulate density in

Sarychat was 3.80 (95% CI 2.47–5.72) individuals km-2. We did not record

argali in Koiluu, whereas the density of ibex was 0.75 (95% CI

0.50–1.27) individuals km-2. While strictly protected areas can achieve

high densities of mountain ungulates, multi-use areas can harbour

meaningful

though suppressed populations. Conservation of mountain ungulates and

their predators can be enhanced by maintaining Sarychat-like “pristine”

areas interspersed within a matrix of multi-use areas like Koiluu.

  Title Landscape resistance to gene flow in a snow leopard population from Qilianshan National Park, Gansu, China Type Journal Article
  Year 2023 Publication (down) Landscape Ecology Abbreviated Journal  
  Volume Issue Pages  
  Keywords Landscape genetics · MLPE · Gene flow · Genetic distance · Isolation by distance · Isolation by resistance · Landscape resistance · Snow leopard · Principal component analysis  
  Abstract Context: The accurate estimation of landscape resistance to movement is important for ecological understanding and conservation applications. Rigorous estimation of resistance requires validation and optimization. One approach uses genetic data for the optimization or validation of resistance models. Objectives We used a genetic dataset of snow leopards from China to evaluate how landscape genetics resistance models varied across genetic distances and spatial scales of analysis. We evaluated whether landscape genetics models were superior to models of resistance derived from habitat suitability or isolation-by-distance.

Methods: We regressed genetically optimized, habitat-based, and isolation-by-distance hypotheses against genetic distances using mixed effect models. We explored all subset combinations of genetically optimized variables to find the most supported resistance scenario for each genetic distance.

Results: Genetically optimized models always out-performed habitat-based and isolation-by-distance hypotheses. The choice of genetic distances influenced the apparent influence of variables, their spatial scales and their functional response shapes, producing divergent resistance scenarios. Gene flow in snow leopards was largely facilitated by areas of intermediate ruggedness at intermediate elevations corresponding to small-to-large valleys within and between the mountain ranges.

Conclusions: This study highlights that landscape genetics models provide superior estimation of functional dispersal than habitat surrogates and suggests that optimization of genetic distance should be included as an optimization routine in landscape genetics, along with variables, scales, effect size and functional response shape. Furthermore, our study provides new insights on the ecological conditions that promote gene flow in snow leopards, which expands ecological knowledge, and we hope will improve conservation planning.

  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.

  Title Predicting and reducing potential parasite infection between migratory livestock and resident Asiatic ibex of Pin valley, India Type Journal Article
  Year 2024 Publication (down) Journal of Biosciences Abbreviated Journal  
  Volume 49 Issue 50 Pages 1-14  
  Keywords Disease; epidemiology; gastrointestinal nematode; intervention; parasite; ungulate  
  Abstract Disease cross-transmission between wild and domestic ungulates can negatively impact livelihoods and wildlife conservation. In Pin valley, migratory sheep and goats share pastures seasonally with the resident Asiatic ibex (Capra sibirica), leading to potential disease cross-transmission. Focussing on gastro-intestinal nematodes (GINs) as determinants of health in ungulates, we hypothesized that infection on pastures would increase over summer from contamination by migrating livestock. Consequently, interventions in livestock that are well-timed should reduce infection pressure for ibex. Using a parasite life-cycle model, that predicts infective larval availability, we investigated GIN transmission dynamics and evaluated potential interventions. Migratory livestock were predicted to contribute most infective larvae onto shared pastures due to higher density and parasite levels, driving infections in both livestock and ibex. The model predicted a c.30-day anti- parasitic intervention towards the end of the livestock’s time in Pin would be most effective at reducing GINs in both hosts. Albeit with the caveats of not being able to provide evidence of interspecific parasite trans- mission due to the inability to identify parasite species, this case demonstrates the usefulness of our predictive model for investigating parasite transmission in landscapes where domestic and wild ungulates share pastures. Additionally, it suggests management options for further investigation.

  Title Ecosystem service dependence in livestock and crop-based Type Journal Article
  Year 2020 Publication (down) Journal of Arid Environments Abbreviated Journal  
  Volume 180 Issue Pages 1-10  
  Keywords Provisioning services Arid ecosystems Local communities Land-use  
  Abstract Globally, in semi-arid and arid landscapes, there is an

ongoing transition from livestock-production systems to crop-production

systems, and in many parts of Asia's arid mountains, mining for minerals

is also increasing. These changes are accompanied by a change in the

generation and quality of ecosystem services (ES), which can impact

human well-being. In this study, to better understand the impacts of

such transitions, we quantified ES in two crop-based and three

livestock-based production systems in the arid and semi-arid landscapes

of the High Himalaya and Central Asia, specifically in the Indian

Himalaya, Kyrgyz Tien Shan, and Mongolian Altai. Our results showed 1)

high economic dependence (3.6–38 times the respective annual household

income) of local farmers on provisioning ES, with the economic value of

ES being greater in livestock-production systems (7.4–38 times the

annual household income) compared to crop-production systems (3.6–3.7

times the annual household income); 2) ES input into cashmere

production, the main commodity from the livestock-production systems,

was 13–18 times greater than the price of cashmere received by the

farmer; and 3) in the livestock production systems affected by mining,

impacts on ES and quality of life were reported to be negative by

majority of the respondents. We conclude that livestock-based systems

may be relatively more vulnerable to degrading impacts of mining and

other ongoing developments due to their dependence on larger ES resource

catchments that tend to have weaker land tenure and are prone to

fragmentation. In contrast to the general assumption of low value of ES

in arid and semi-arid landscapes due to relatively low primary

productivity, our study underscores the remarkably high importance of ES

in supporting local livelihoods.

  Title Can livestock grazing dampen density-dependent fluctuations in wild herbivore populations? Type Journal Article
  Year 2024 Publication (down) Journal of Applied Ecology Abbreviated Journal  
  Volume Issue Pages 1-12  
  Keywords competition, Gompertz state-space model, Himalaya, livestock, long-term study, negative density dependence, recruitment  
  Abstract 1. Conservation policy for the high mountains of Asia increasingly recognises the need to encompass large multi-use landscapes beyond the protected area network. Due to limited long-term research in this region, our understanding of even fundamental processes, such as factors regulating large mammal populations is poor.

2. Understanding the factors that regulate animal populations, especially those generating cyclicity, is a long-standing problem in ecology. Long-term research across multiple taxa (mainly from Europe and North America) has focussed on the relative roles of food and predation in generating cyclicity in population dynamics. It remains unclear how trophic interactions that are influenced by anthropogenic stressors can affect population dynamics in human-modified landscapes.

3. We present a 10-year study to compare the effects of livestock grazing on density-dependent dynamics in two populations of bharal, Pseudois nayaur, in the Himalayas. We combine this with a mechanistic understanding of whether density dependence in these two sites acts predominantly by affecting adult survival or recruitment. We compared and quantified density dependence in the bharal population by fitting Bayesian Gompertz state-space models.

4. We found evidence for negative density dependence which indicates possible cyclic dynamics in the bharal population of the site (Tabo) with low livestock density. The population dynamics of this site were driven by recruited offspring—with a 2-year density-dependent lag effect—rather than adult survival. In the site with high livestock density (Kibber), this density dependence was not detected. We postulate the potential role of excessive grazing by livestock in affecting offspring recruitment, thereby affecting the bharal population in Kibber.

5. Synthesis and applications: Our results suggest that conservation action to facilitate wild herbivore population recovery, such as the development of protected areas and village reserves, needs to account for density-dependent regulation. Sites with trophy hunting require continuous monitoring to understand the effects of density dependence so that appropriate hunting quotas can be formulated.
