  Title (down) Predicting Parasite Dynamics in Mixed-Use Trans-Himalayan Pastures to Underpin Management of Cross-Transmission Between Livestock and Bharal Type Journal Article
  Year 2021 Publication Frontiers in Veterinary Science Abbreviated Journal  
  Volume 8 Issue 714241 Pages 1 - 21  
  Keywords disease, Trans-Himalaya, livestock, nematodes, bharal, model, ungulates, grazing  
  Abstract The complexities of multi-use landscapes require sophisticated approaches to addressing disease transmission risks. We explored gastro-intestinal nematode (GINs) infections in the North India Trans-Himalayas through a socio-ecological lens, integrating parasite transmission modelling with field surveys and local knowledge, and evaluated the likely effectiveness of potential interventions. Bharal (blue sheep; Pseudois nayaur), a native wild herbivore, and livestock share pasture year-round and livestock commonly show signs of GINs infection. While both wild and domestic ungulates had GINs infections, egg counts indicated significantly higher parasite burdens in bharal than livestock. However, due to higher livestock densities, they contributed more to the total count of eggs and infective larvae on pasture. Herders also reported health issues in their sheep and goats consistent with parasite infections. Model simulations suggested that pasture infectivity in this system is governed by historical pasture use and gradually accumulated larval development during the summer, with no distinct short-term flashpoints for transmission. The most effective intervention was consequently predicted to be early-season parasite suppression in livestock using temperature in spring as a cue. A 1-month pause in egg output from livestock could lead to a reduction in total annual availability of infective larvae on pasture of 76%, potentially benefitting the health of both livestock and bharal. Modelling suggested that climate change over the past 33 years has led to no overall change in GINs transmission potential, but an increase in the relative influence of temperature over precipitation in driving pasture infectivity. Our study provides a transferable multi-pronged approach to investigating disease transmission, in order to support herders’ livelihoods and conserve wild ungulates.

  Title (down) Predicting Habitat Suitability of Snow Leopards in the Western Himalayan Mountains, India Type Journal Article
  Year 2020 Publication Biology bulletin Abbreviated Journal  
  Volume 47 Issue 6 Pages 655-664  
  Keywords biogeographic distribution, climate, endangered cat, MaxEnt, snow leopard  
  Abstract The population of snow leopard (Panthera uncia) is declining

across their range, due to poaching, habitat fragmentation, retaliatory

killing, and a decrease of wild prey species. Obtaining information on

rare and cryptic predators living in remote and rugged terrain is

important for making conservation and management strategies. We used the

Maximum Entropy (MaxEnt) ecological niche modeling framework to predict

the potential habitat of snow leopards across the western Himalayan

region, India. The model was developed using 34 spatial species

occurrence points in the western Himalaya, and 26 parameters including,

prey species distribution, temperature, precipitation, land use and land

cover (LULC), slope, aspect, terrain ruggedness and altitude. Thirteen

variables contributed 98.6% towards predicting the distribution of snow

leopards. The area under the curve (AUC) score was high (0.994) for the

training data from our model, which indicates pre- dictive ability of

the model. The model predicted that there was 42432 km2 of potential

habitat for snow leop- ards in the western Himalaya region. Protected

status was available for 11247 km2 (26.5%), but the other 31185 km2

(73.5%) of potential habitat did not have any protected status. Thus,

our approach is useful for predicting the distribution and suitable

habitats and can focus field surveys in selected areas to save

resources, increase survey success, and improve conservation efforts for

snow leopards.

  Title (down) Predicting carnivore habitat use and livestock depredation risk with false-positive multi-state occupancy models Type Journal Article
  Year 2022 Publication Biological Conservation Abbreviated Journal  
  Volume 271 Issue 109588 Pages 1-10  
  Keywords Bayesian hierarchical model,False-positive,Multi-state occupancy,Human-carnivore conflict,Livestock depredation,Snow leopard,Lynx,Wolf,Bear  
  Abstract The cycle of livestock depredation and retaliatory killing constitutes a major threat to large carnivores worldwide and imposes considerable hardships on human communities. Mitigation efforts are often undertaken with little knowledge of ecological underpinnings and patterns of depredation, limiting conservationists' ability to develop, prioritize, and evaluate solutions. Carnivore detection and depredation data from interviews in affected communities may help address this gap, but such data are often prone to false-positive uncertainty. To address these challenges in the Pamir Mountains of Tajikistan we collected snow leopard, lynx, wolf, and bear detection and depredation reports from local communities via semi-structured interviews. We used a novel hierarchical multi-species multi-state occupancy model that accounted for potential false-positives to investigate carnivore site use and depredation concurrently with respondents' apparent vulnerability to that risk. Estimated false-positive probabilities were small, but failure to account for them overstated site use probabilities and depredation risk for all species. Although individual vulnerability was low, depredation was nonetheless commonplace. Carnivore site use was driven by clear habitat associations, but we did not identify any clearly important large-scale spatial correlates of depredation risk despite considerable spatial variation in that risk. Respondents who sheltered livestock in household corrals reinforced with wire mesh were less likely to report snow leopard depredations. Reducing depredation and retaliation at adequately large scales in the Pamirs will likely require a portfolio of species-specific strategies, including widespread proactive corral improvements. Our approach expanded inference on the often-cryptic processes surrounding human-carnivore conflict even though structured wildlife data were scarce.

  Title (down) Predicting and reducing potential parasite infection between migratory livestock and resident Asiatic ibex of Pin valley, India Type Journal Article
  Year 2024 Publication 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 (down) Predator niche overlap and partitioning and potential interactions in the mountains of Central Asia Type Journal Article
  Year 2022 Publication Journal of Mammalogy Abbreviated Journal  
  Volume XX(X) Issue Pages 1-11  
  Keywords intraguild interactions, niche partitioning, snow leopard, spatial capture–recapture, wolf  
  Abstract Direct and indirect interactions among predators affect predator fitness, distribution, and overall community structure. Yet, outside of experimental settings, such interactions are difficult to observe and thus poorly understood. Patterns of niche overlap among predators reflect and shape community interactions and may therefore help elucidate the nature and intensity of intraguild interactions. To better understand the coexistence of two apex predators, snow leopards (Panthera uncia) and wolves (Canis lupus), we investigated their spatial, temporal, and dietary niche overlap in summer in the Pamir Mountains of Tajikistan. We estimated population- level space use via spatial capture–recapture models based on noninvasive genetics and camera traps, diel activity patterns based on camera trap detections, and diet composition from prey remains in carnivore scats, from which we estimated coefficients between 0 and 1 for overlap in space, time, and diet, respectively. Snow leopards and wolves displayed moderate spatial partitioning (0.26, 95% confidence interval [CI]: 0.17–37), but overlapping temporal (0.77, 95% CI: 0.64–0.90) and dietary (0.97, 95% CI: 0.80–0.99) niches. Both predators relied on seasonally abundant marmots (Marmota caudata) rather than wild ungulates, their typical primary prey, suggesting that despite patterns of overlap that were superficially conducive to exploitation competition and predator facilitation, prey were likely not a limiting factor. Therefore, prey-mediated interactions, if present, were unlikely to be a major structuring force in the ecosystem. By implication, carnivore conservation planning and monitoring in the mountains of Central Asia should more fully account for the seasonal importance of marmots in the ecosystem.

  Title (down) 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 (down) Population monitoring of snow leopards using camera trapping in Naryn State Nature Reserve, Kyrgyzstan, between 2016 and 2019 Type Journal Article
  Year 2021 Publication Global Ecology and Conservation Abbreviated Journal  
  Volume 31 Issue e01850 Pages 1-6  
  Keywords Snow leopard, camera trapping, Citizen science, Kyrgyzstan  
  Abstract Four field seasons of snow leopard (Panthera uncia) camera trapping inside Naryn State Nature Reserve, Kyrgyzstan, performed thanks to citizen science expeditions, allowed detecting a minimal population of five adults, caught every year with an equilibrated sex ratio (1.5:1) and reproduction: five cubs or subadults have been identified from three litters of two different females. Crossings were observed one to three times a year, in front of most camera traps, and several times a month in front of one of them. Overlap of adults’ minimal territories was observed in front of several camera traps, regardless of their sex. Significant snow leopard presence was detected in the buffer area and at Ulan area which is situated at the reserve border. To avoid poaching on this apex predator and its preys, extending the more stringent protection measures of the core zone to both the Southern buffer area and land adjacent to Ulan is recommended.

  Title (down) Population density of snow leopards (Panthera Uncia) in the Yage Valley Region of the Sanjiangyuan National Park: Conservation Implications and future directions Type Journal Article
  Year 2020 Publication Artic, Antartic and Alpine Research Abbreviated Journal  
  Volume 52 Issue 1 Pages 541-550  
  Keywords Snow leopard; population density; camera trapping; Tibetan Plateau; alpine ecosystem  
  Abstract Population-based studies on snow leopard (Panthera uncia) are of theoretical and practical sig- nificance for the conservation of alpine ecosystems, though geographic remoteness and isolation hinder surveys in many promising regions. The Sanjiangyuan National Park on the Tibetan Plateau is acknowledged as a main snow leopard habitat, but most of the region remains unexplored and unknown. We adopted a combined approach of route survey and camera trapping survey to explore the population density of snow leopard in the Yage Valley region of the Sanjiangyuan National Park. Results indicated that (1) large populations of blue sheep contributed to the major food supply for snow leopards, along with diverse prey species as dietary supplementations, and (2) a population density of four to six snow leopards per 100 km2 on the north bank was estimated, and nine to fourteen individuals within the valley core areas were identified. We also argue that under the potential impacts of hydropower dams, this valley ecosystem should be symbolized as a conservation hotspot and therefore merits prioritized conservation. We recommend further surveys combined with novel methods/techniques and advocate a sustainable ecotourism model for the first V-shaped valley along the Yangtze mainstream.

  Title (down) Patterns of livestock depredation by snow leopards and effects of intervention strategies: lessons from the Nepalese Himalaya Type Journal Article
  Year 2022 Publication Wildlife Research Abbreviated Journal  
  Volume Issue Pages  
  Keywords Annapurna, co-existence, conservation biology, highland communities, human–wildlife conflict, large carnivore, livestock depredation, Panthera uncia, prey selection, snow leopard.  
  Abstract Context: Large carnivores are increasingly threatened by anthropogenic activities, and their protection is among the main goals of biodiversity conservation. The snow leopard (Panthera uncia) inhabits high-mountain landscapes where livestock depredation drives it into conflicts with local people and poses an obstacle for its conservation.

Aims: The aim of this study was to identify the livestock groups most vulnerable to depredation, target them in implementation of practical interventions, and assess the effectiveness of intervention strategies for conflict mitigation. We present a novel attempt to evaluate intervention strategies for particularly vulnerable species, age groups, time, and seasons.

Methods: In 2020, we conducted questionnaire surveys in two regions of the Annapurna Conservation Area, Nepal (Manang, n = 146 respondents and Upper Mustang, n = 183). We applied sample comparison testing, Jacobs’ selectivity index, and generalised linear models (GLMs) to assess rates and spatio-temporal heterogeneity of depredation, reveal vulnerable livestock groups, analyse potential effects of applied intervention strategies, and identify husbandry factors relevant to depredation.

Key results: Snow leopard predation was a major cause of livestock mortality in both regions (25.4–39.8%), resulting in an estimated annual loss of 3.2–3.6% of all livestock. The main intervention strategies (e.g. corrals during night-time and herding during daytime) were applied inconsistently and not associated with decreases in reported livestock losses. In contrast, we found some evidence that dogs, deterrents (light, music playing, flapping tape, and dung burning), and the use of multiple interventions were associated with a reduction in reported night-time depredation of yaks.

Conclusions and implications: We suggest conducting controlled randomised experiments for quantitative assessment of the effectiveness of dogs, deterrents, and the use of multiple interventions, and widely applying the most effective ones in local communities. This would benefit the long-term co-existence of snow leopards and humans in the Annapurna region and beyond.

  Title (down) Patterns of Livestock Depredation and Large Carnivore Conservation Implications in the Indian Trans-Himalaya Type Journal Article
  Year 2020 Publication Journal of Arid Environments Abbreviated Journal  
  Volume Issue Pages 1-5  
  Keywords Large carnivores Livestock depredation Participatory approach Snow leopard Kargil Himalaya  
  Abstract Livestock is one of the major sources of livelihood for the

agro-pastoral communities in central and south Asia. Livestock

depredation by large carnivores is a wide-ranging issue that leads to

economic losses and a deviance from co-existence. We investigated the

grass root factors causing livestock depredation in Kargil, Ladakh and

tested the findings of diet analysis in validating reported livestock

depredation. Globally vulnerable snow leopard (Panthera uncia) and more

common wolf (Canis lupus) were the two main wild predators. A total of

1113 heads of livestock were reportedly killed by wolf (43.6%) followed

by unknown predators (31.4%) and snow leopard (21.5%) in the study site

from 2009 to 2012, which comes to 2.8% annual livestock losses. Scat

analysis also revealed a significant amount of livestock in the diet of

snow leopard (47%) and wolf (51%). Poor livestock husbandry practices

and traditional livestock corrals were found to be the major drivers

contributing in the livestock depredation. Based on the research

findings, we worked with the local communities to sensitize them about

wildlife conservation and extended limited support for predator proof

livestock corrals at a small scale. Eventually it helped in reducing

conflict level and conserving the globally threatened carnivores. We

conclude that a participatory approach has been successful to generate

an example in reducing large carnivore-human conflict in the west

Himalaya.
