Title Prey behavior leads to predator: a case study of the Himalayan tahr and the snow leopard in Sagarmatha (Mt. Everest) National Park, Nepal Type Journal Article
Year 2009 Publication Israel Journal of Ecology & Evolution Abbreviated Journal
Volume 55 Issue 4 Pages 315-327
Keywords vigilance, fear, behavioral indicator, predator, prey, snow leopard, Himalayan tahr, Mount Everest
Abstract Rare, elusive predators offer few sightings, hindering research with small sample sizes and lack of experimentation. While predators may be elusive, their prey are more readily observed. Prey respond to the presence of a predator, and these fear responses may have population- and community-level consequences. Anti-predator behaviors, such as vigilance, allow us to sidestep the difficulty of direct field studies of large predators by studying them indirectly. Here we used a behavioral indicator, the vigilance behavior of the Himalayan tahr, the snow leopard’s main local prey, to reveal the distribution and habitat use of snow leopards in the Mt. Everest region of Nepal. We combined techniques of conventional field biology with concepts of foraging theory to study prey behavior in order to obtain insights into the predator’s ecology. The Himalayan tahr’s vigilance behavior correlates with the distribution of snow leopard signs. Tahr actually led us to six sightings of snow leopards. We conclude that behavioral indicators provided by prey offer a valuable tool for studying and monitoring stealthy and rare carnivores.

Title The snow leopard in Himalaya: A step towards their conservation by studying their distribution, marking habitat selection, coexistence with other predators, and wild prey-livestock-predator interaction Type Journal Article
Year 2006 Publication Conservation Biology in Asia Abbreviated Journal
Volume Issue Pages 184-196
Keywords Himalaya, Nepal, ecology, snow leopard, Uncia uncia, prey, livestock, predator
Abstract Snow leopard (Uncia uncial) is a flagship species of the Himalaya. Very few studies have been done on the ecology of this species in the Himalaya. This paper presents an overview of four studies conducted on snow leopards in Nepal and India, dealing with various aspects of snow leopard ecology including their status assessment, making behaviour, habitat selection, food habits, and impact on livestock. The information generated by these studies is useful in planning effective conservation and management strategies for this endangered top predator of high mountains.

Title Movement patterns of snow leopard (Panthera uncia) around kills based on GPS location clusters Type Report
Year 2011 Publication Abbreviated Journal
Volume Issue Pages
Keywords snow leopard, Panthera, Mongolia, Snow Leopard Trust, predator, prey, kill, behavior
Abstract Research concerning movement patterns of wild animals has been advancing since GPS technology arrived. But studying the snow leopard (Panthera uncia) is still difficult because of the harsh territory it inhabits in Central Asia. This study took place in south Gobi, Mongolia, and aimed to estimate the time spent at kills and the maximum distance away from kills between visits. Snow leopards were monitored with GPS collars that took a location every five or seven hours. Potential kill sites were established by identifying clusters of GPS-locations in ArcGIS and visited in the field for confirmation. ArcGIS was used to calculate the distance between cluster and GPS-locations. I used two buffer zones (100 m and 500 m radius) to define the time snow leopards spent at kills. It was found that snow leopard age and prey category affected time spent at kills and also that snow leopard sex together with prey category affected the maximum distance moved away from kills between visits. Season had no significant effect on either time at kills or distance moved away from kills between visits. Snow leopards spent on average 3.2 days at their kills in the 100 m buffer zone and 3.5 days at their kills in the 500 m buffer zone. Subadults stayed longer at kills than adults and animals of both age categories spent longer time on larger prey. The mean maximum distance moved away from kills between visits was 179 m in the 100 m buffer zone and 252 m in the 500 m buffer zone. Female snow leopards moved further away from kills between visits than male snow leopards. Both the number of days spent on kills and maximum distance moved away from kills between visits increased when kills consisted of more than one animal. This study has provided some basic information on snow leopard behaviors around their kills but also highlights the need to monitor more snow leopards before more solid conclusions can be drawn as this study was based on based on a relatively small sample.

Title Recovery of the snow leopard in Sagarmatha (Mt.Everest) National Park: effects on main prey Type Journal Article
Year 2014 Publication European Journal of Wildlife Research Abbreviated Journal
Volume Issue 60 Pages 559-562
Keywords Predator–prey relationships . Small populations . Snow leopard . Himalayan tahr
Abstract Consequences of predation may be particularly

heavy on small populations of herbivores, especially if they

are threatened with extinction. Over the 2006–2010 period, we

documented the effects of the spontaneous return of the endangered

snow leopard on the population of the vulnerable

Himalayan tahr. The study area was an area of central

Himalaya where this cat disappeared c. 40 years before, because

of persecution by man. Snow leopards occurred mainly

in areas close to the core area of tahr distribution. Tahr was the

staple (56.3 %) of snow leopards. After the arrival of this cat,

tahr decreased by more than 2/3 from 2003 to 2010 (mainly

through predation on kids). Subsequently, the density of snow

leopards decreased by 60%from2007 to 2010. The main prey

of snow leopards in Asia (bharal, marmots) were absent in our

study area, forcing snow leopards to specialize on tahr. The

restoration of a complete prey spectrum should be favoured

through reintroductions, to conserve large carnivores and to

reduce exploitation of small populations of herbivores, especially

if threatened.

Title Predation may counteract climatic change as a driving force for movements of mountain ungulates Type Report
Year 2016 Publication Behavioural-Processes Abbreviated Journal
Volume Issue 129 Pages 101-104
Keywords Climate change, Environmental change, Interspecific interactions, Large cats, Predator-prey interactions
Abstract Temperature variations are expected to influence altitudinal movements of mountain herbivores and, in

turn, those of their predators, but relevant information is scarce. We evaluated monthly relationships

between temperature and altitude used by a large mountain-dwelling herbivore, the Himalayan tahr

Hemitragus jemlahicus, and its main predator, the snow leopard Panthera uncia, in an area of central

Himalaya for five consecutive years (2006–2010). In contrast to expectations, there was no significant

direct relationship between altitude of tahr sightings and temperature. The mean altitude of tahr sightings

decreased by c. 200 m throughout our study. As expected, snow leopard movements tracked those of tahr,

although the core area of the snow leopard did not move downwards. Tahr remained the staple of the

snow leopard diet: we suggest that the former did not move upwards in reaction to higher temperature

to avoid encounters with the latter. Avoidance of competition with the larger common leopard Panthera

pardus at lower altitudes could explain why snow leopards did not shift their core area downwards.

Apparently, interspecific interactions (predation; competition) influenced movements of Himalayan tahr

and snow leopards more than climatic variations.

Title Impact of wild prey availability on livestock predation by snow leopards Type Journal Article
Year Publication Royal Society Open Science Abbreviated Journal
Volume Issue Pages 1-11
Keywords apparent competition, apparent facilitation, conservation conflicts, indirect interactions, predator&#65533; prey interactions, snow leopard
Abstract An increasing proportion of the world&#65533;s poor is rearing livestock today, and the global livestock population is growing. Livestock predation by large carnivores and their retaliatory

killing is becoming an economic and conservation concern. A common recommendation for carnivore conservation and for reducing predation on livestock is to increase wild prey populations based on the assumption that the carnivores will consume this alternative food. Livestock predation, however, could either reduce or intensify with increases in wild prey depending on prey choice and trends in carnivore abundance. We show that the extent of livestock predation by the endangered snow leopard Panthera uncia

intensifies with increases in the density of wild ungulate prey, and subsequently stabilizes. We found that snow leopard density, estimated at seven sites, was a positive linear function of the density of wild ungulates&#65533;the preferred prey&#65533;and showed no discernible relationship with livestock density. We also found that modelled livestock predation increased with livestock density. Our results suggest that snow leopard conservation would benefit from an increase in wild ungulates, but that would intensify the problem of livestock predation for pastoralists. The potential benefits of increased wild prey abundance in reducing livestock predation

can be overwhelmed by a resultant increase in snow leopard populations. Snow leopard conservation efforts aimed atfacilitating increases in wild prey must be accompanied by greater assistance for better livestock

protection and offsetting the economic damage caused by carnivores.

Title Livestock depredation by snow leopard and Tibetan wolf: Implications for herders&#65533; livelihoods in Wangchuck Centennial National Park, Bhutan Type Journal Article
Year 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 In the shadows of snow leopards and the Himalayas: density and habitat selection of blue sheep in Manang, Nepal Type Journal Article
Year 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 Ungulate spatiotemporal responses to contrasting predation risk from wolves and snow leopards Type Journal Article
Year 2022 Publication Journal of Animal Ecology Abbreviated Journal
Volume Issue Pages 1-16
Keywords landscape of fear, multiple-predator effects, non-consumptive effects, predation-risk effects, predator facilitation, risk allocation, snow leopard, wolf
Abstract 1. Spatial responses to risk from multiple predators can precipitate emergent consequences for prey (i.e. multiple-predator effects, MPEs) and mediate indirect interactions between predators. How prey navigate risk from multiple predators may therefore have important ramifications for understanding the propagation of predation-risk effects (PREs) through ecosystems.

2. The interaction of predator and prey traits has emerged as a potentially key driver of antipredator behaviour but remains underexplored in large vertebrate systems, particularly where sympatric prey share multiple predators. We sought to better generalize our understanding of how predators influence their ecosystems by considering how multiple sources of contingency drive prey distribution in a multi-predator–multi-prey system.

3. Specifically, we explored how two sympatric ungulates with different escape tactics—vertically agile, scrambling ibex Capra sibirica and sprinting argali Ovis ammon—responded to predation risk from shared predators with contrasting hunting modes—cursorial wolves Canis lupus and vertical-ambushing, stalking snow leopards Panthera uncia.

4. Contrasting risk posed by the two predators presented prey with clear trade-offs. Ibex selected for greater exposure to chronic long-term risk from snow leopards, and argali for wolves, in a nearly symmetrical manner that was predictable based on the compatibility of their respective traits. Yet, acute short-term risk from the same predator upended these long-term strategies, increasing each ungulates' exposure to risk from the alternate predator in a manner consistent with a scenario in which conflicting antipredator behaviours precipitate risk-enhancing MPEs and mediate predator facilitation. By contrast, reactive responses to wolves led ibex to reduce their exposure to risk from both predators—a risk-reducing MPE. Evidence of a similar reactive risk-reducing effect for argali vis-à-vis snow leopards was lacking.

5. Our results suggest that prey spatial responses and any resulting MPEs and prey-mediated interactions between predators are contingent on the interplay of hunting mode and escape tactics. Further investigation of interactions among various drivers of contingency in PREs will contribute to a more comprehensive understanding and improved forecasting of the ecological effects of predators.
