  Title The contingencies of group size and vigilance Type Miscellaneous
  Year 2007 Publication Evolutionary Ecology Research, Abbreviated Journal  
  Volume 9 Issue Pages 1263-1276  
  Keywords attraction effect,contingency,dilution effect,fitness,group-size effect,many-eyes effect,predation risk,vigilance behaviour; predation; decline; potential; predators; predator; feeding; Animals; Animal; use; food; effects; Relationship; behaviour; methods; game; Interactions; interaction; factor; value; Energy  
  Abstract Background: Predation risk declines non-linearly with one's own vigilance and the vigilance of others in the group (the 'many-eyes' effect). Furthermore, as group size increases, the individual's risk of predation may decline through dilution with more potential victims, but may increase if larger groups attract more predators. These are known, respectively, as the dilution effect and the attraction effect.

Assumptions: Feeding animals use vigilance to trade-off food and safety. Net feeding rate declines linearly with vigilance.

Question: How do the many-eyes, dilution, and attraction effects interact to influence the relationship between group size and vigilance behaviour?

Mathematical methods: We use game theory and the fitness-generating function to determine the ESS level of vigilance of an individual within a group.

Predictions: Vigilance decreases with group size as a consequence of the many-eyes and dilution effects but increases with group size as a consequence of the attraction effect, when they act independent of each other. Their synergetic effects on vigilance depend upon the relative strengths of each and their interactions. Regardless, the influence of other factors on vigilance – such as encounter rate with predators, predator lethality, marginal value of energy, and value of vigilance – decline with group size.

  Title Patterns of human interaction with snow leopard and co-predators in the Mongolian western Altai: Current issues and perspectives Type Journal Article
  Year 2020 Publication Global Ecology and Conservation Abbreviated Journal  
  Volume 24 Issue Pages 1-21  
  Keywords Depredation Human-carnivores interaction Mongolian altai Snow leopard Wolf Wolverine  
  Abstract Large carnivores can cause considerable economic damage,

mainly due to livestock depredation. These conficts instigate negative

attitude towards their conservation, which could in the extreme case

lead to retaliatory killing. Here we focus on the snow leopard (Panthera

uncia), a species of conservation concern with particularly large

spatial requirements. We conducted the study in the Bayan Olgii

province, one of the poorest provinces of Mongolia, where the majority

of the human population are traditional herders. We conducted a survey

among herders (N 261) through a semi-structured questionnaire with the

aim to assess: the current and future herding practices and prevention

measures, herders’ perceptions and knowledge of the environmental

protection and hunting laws; the perceived livestock losses to snow

leopard, wolf (Canis lupus), and wolverine (Gulo gulo), as well as to

non-predatory factors; the key factors affecting livestock losses to

these three large carnivores; and, finally, the attitudes towards these

three large carnivores. Non-predatory causes of mortality were slightly

higher than depredation cases, representing 4.5% and 4.3% of livestock

holdings respectively. While no depredation of livestock was reported

from wolverines, snow leopard and wolf depredation made up 0.2% and 4.1%

of total livestock holdings, respectively. Herders’ attitudes towards

the three large carnivores were negatively affected by the magnitude of

the damages since they had a positive overall attitude towards both snow

leopard and wolverine, whereas the attitude towards wolf was negative.

We discuss conservation and management options to mitigate herder-snow

leopard impacts. To palliate the negative consequences of the increasing

trend in livestock numbers, herd size reduction should be encouraged by

adding economic value to the individual livestock and/or by promoting

alternative income and/or ecotourism. Furthermore, co-management between

government and stakeholders would help tackle this complex problem, with

herders playing a major role in the development of livestock management

strategies. Traditional practices, such as regularly shifting campsites

and using dogs and corrals at night, could reduce livestock losses

caused by snow leopards.

  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 Snow Leopard (Uncia uncia) and Human Interaction in Phoo Village in the Annapurna Conservation Area, Nepal Type Miscellaneous
  Year 2004 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords phoo; annapurna conservation area; Nepal; livestock; human interaction; conflict management; yaks; goats; sheep; horse; corral; 5280  
  Abstract Phoo village in the Annapurna Conservation Area (ACA) in Nepal is located at 4,052 m als physically

in the central north of the country. Livestock keeping is the main activity of the people for making a

living amidst a conflict with snow leopard (Uncia uncia). Each year snow leopard kills a number of

livestock resulting significant economic losses for the poor people living in this remote area. Unless

the people – snow leopard conflict is well understood and appropriate conflict management activities

are implemented, the long run co-existence between people and snow leopard – especially the

existence of snow leopard in this part of the world -will be in question. This has now become an

utmost important as the aspiration of the people for economic development has risen significantly and

the area has been opened to tourism since spring 2002. In addition to this, the globalisation process has

directly and indirectly affected the traditional resource management practices and co-existence

strategies of many traditional societies including Phoo.

The livestock depredation for 3 years (2001 – 2004) by snow leopard was studied by interviewing the

herders to understand the responsible and specific bio-physical and socio-economic factors. The study

revealed that goats are most depredated species followed by sheep. Winter months (January – April)

and winter pastures are most vulnerable to snow leopard predation. Presence of bushes, forest and

boulders make good hides for snow leopard resulting into high depredation. The study also showed

that a lax animal guarding system was significantly responsible for high livestock depredation by snow

leopard.

The study showed that improvement in livestock guarding system should be adopted as the most

important activity. However despite the importance of livestock in the economy of Phoo it is still not

well understood why the herders neglect for proper livestock guarding. This requires further study.

Proper guarding system is required especially in winter season in winter pastures. It is also suggested

that there should be changes in the composition of livestock species by promoting more yaks and

discouraging or minimising goats. Yaks and large animals are less depredated and small animals like

goats and sheep are highly depredated by snow leopard. A trend was also observed in Phoo village

where there is an increase in the number of yaks and a decrease in the number of goats over last few

years. This could be a management response of the herders to livestock depredation. Other protective

measures of the livestock at the corrals have also been recommended including promotion of guard

dogs and other measures.

Since the area is opened for tourism, it is suggested that the tourism opportunity for the economic

development of the area should be grasped so that the heavy dependence on livestock raising would be

minimised. This will help minimise the number of human – snow leopard conflicts.

  Title 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 Pastoralist experience and tolerance of snow leopard, wolf and lynx predation in Karakoram Pamir Mountains Type Journal Article
  Year 2014 Publication Journal of Biodiversity and Envirnomental Sciences Abbreviated Journal  
  Volume 5 Issue 4 Pages 214-229  
  Keywords Carnivore, herbivores, interaction, Karakoram, Pamir, Khunjerab, Taxkorgan, China, Pakistan  
  Abstract Human-carnivore conflict is a common conservation and livelihood issue in mountain communities. This study was conducted to understand nature and extent of socio-ecological interaction between pastoralism and wildlife conservation in cold deserts of Karakoram Pamir Mountains (KPM) between China and Pakistan. Study revealed that livestock depredation is a burning issue in KPM with varying intensity from place to place, depending upon wild prey abundance, herd size, herding practices, predator type and age. Snow leopard, wolf and lynx were the major predators, while Brown bear despite its presence was reported being less fatal to livestock. Snow leopard killed highest number of animals (88.7% n=1440) mostly sheep and goats whereas, wolf killed more juvenile yaks. Lynx was found occasionally predating on young domestic crop. Highest number of kills was recorded from pastures during summer months (July-Aug) when animals were free grazing or were kept inside pens at night. Wild prey base being abysmally low, livestock seemed offering a considerable portion of diet to carnivores. Despite considerable losses from carnivores, more respondents in KNP (Pakistan) buffer zone had sympathies for predators compared to those in TNR (China) who were annoyed of the carnivores. Although people attributed escalating human-carnivore conflict to a higher level of protection to wild animals in Protected Areas (PA) but efforts are still needed to judiciously integrate conservation with local livelihood and development needs, otherwise herders may continue losing their livestock to predators and retaliatory killing of endangered carnivore species i.e., Snow leopard and Wolf may continue unabated and would further destabilize the fragile mountain ecosystem.

  Abstract Livestock production is the major land-use in Ladakh region of the Indian Trans-Himalaya, and is a crucial sector that drives the region's economy (Anon, 2002). Animal products like meat and milk provide protein to the diet of people, while products like wool and pashmina (soft fibre of goats) find their way to the international market. Such high utility of livestock and the recent socio-economic changes in the region have caused an increase in livestock population (Rawat and Adhikari, 2002; Anon. 2002), which, if continue apace, may increase grazing pressure and deteriorate pasture conditions. Thus, there is an urgent need to assess the impact of such escalation in livestock population on the regions wildlife. Although, competitive interaction between wildlife and livestock has been studied elsewhere in the Trans-Himalaya (Bhatnagar et al., 2000; Mishra, 2001; Bagchi et al., 2002), knowledge on this aspect in the Ladakh region is very rudimentary. The rangelands of Ladakh are characterised by low primary productivity (Chundawat & Rawat, 1994), and the wild herbivores are likely to compete with the burgeoning livestock on these impoverished rangelands (Mishra et al., 2002). Thus, given that the area supports a diverse wild ungulate assemblage of eight species (Fox et al., 1991b), and an increasing livestock population (Rawat and Adhikari, 2002), the nature of interaction between wildlife and livestock needs to be assessed. During this project, we primarily evaluated the influence of domestic sheep and goat grazing on the habitat use of Tibetan argali Ovis ammon hodgsoni in a prospective wildlife reserve in Ladakh.

  Title Changes in ecological conditions may influence intraguild competition: inferring interaction patterns of snow leopard with co-predators Type Journal Article
  Year 2022 Publication PeerJ Abbreviated Journal  
  Volume 10 Issue e14277 Pages 1-26  
  Keywords Common leopard, Woolly wolf, Occupancy, Interspecific interactions, Temporal overlap, Scat analysis  
  Abstract Background: Large-scale changes in habitat conditions due to human modifications and climate change require management practices to consider how species communities can alter amidst these changes. Understanding species interactions across the gradient of space, anthropogenic pressure, and season provide the opportunity to anticipate possible dynamics in the changing scenarios. We studied the interspecific interactions of carnivore species in a high-altitude ecosystem over seasonal (summer and winter) and resource gradients (livestock grazing) to assess the impact of changing abiotic and biotic settings on coexistence.

Methods: The study was conducted in the Upper Bhagirathi basin, Western Himalaya, India. We analyzed around 4 years of camera trap monitoring data to understand seasonal spatial and temporal interactions of the snow leopard with common leopard and woolly wolf were assessed in the greater and trans-Himalayan habitats, respectively. We used two species occupancy models to assess spatial interactions, and circadian activity patterns were used to assess seasonal temporal overlap amongst carnivores. In addition, we examined scats to understand the commonalities in prey selection.

Results: The result showed that although snow leopard and wolves depend on the same limited prey species and show high temporal overlap, habitat heterogeneity and differential habitat use facilitate co-occurrence between these two predators. Snow leopard and common leopard were spatially independent in the summer. Conversely, the common leopard negatively influences the space use of snow leopard in the winter. Limited prey resources (lack of livestock), restricted space (due to snow cover), and similar activity patterns in winter might result in strong competition, causing these species to avoid each other on a spatial scale. The study showed that in addition to species traits and size, ecological settings also play a significant role in deciding the intensity of competition between large carnivores. Climate change and habitat shifts are predicted to increase the spatial overlap between snow leopard and co-predators in the future. In such scenarios, wolves and snow leopards may coexist in a topographically diverse environment, provided sufficient prey are available. However, shifts in tree line might lead to severe competition between common leopards and snow leopards, which could be detrimental to the latter. Further monitoring of resource use across abiotic and biotic environments may improve our understanding of how changing ecological conditions can affect resource partitioning between snow leopards and predators.

  Abstract The Ladakh urial (Ovis vignei vignei) is a highly endangered animal (IUCN Red List 2000) listed in the Appendix 1 of CITES and Schedule 1 of the Indian Wildlife Protection Act 1972. Its numbers had been reduced to a few hundred individuals in the 1960s and 70s through hunting for trophies and meat (Fox et al. 1991, Mallon 1983, Chundawat and Qureshi 1999, IUCN Red List 2000). However, with the protection bestowed by the IWPA 1972, and resultant decrease in hunting, the population seems to have shown a marginal increase to about 1000-1500 individuals in its range in Ladakh (Chundawat and Qureshi 1999, IUCN Red List 2000). Although the species had in the past, been able to coexist with the predominantly Buddhist society of Ladakh, the recent increase in the population of both humans and their livestock has placed immense pressures on its habitat (Shackleton 1997, Chundawat and Qureshi 1999, Raghavan and Bhatnagar 2003). This is especially important considering that the Ladakh urial habitat coincides with the areas of maximum human activity in terms of settlements, agriculture, pastoralism and development, in Ladakh (Fox et al. 1991, Chundawat and Qureshi 1999, Raghavan and Bhatnagar 2003). Increased developmental activities such as construction of roads, dams, and military bases in these areas have also increased the access to their habitat. This has consequently made the species more vulnerable to the threats of poaching and habitat destruction (Fox et al. 1991, Chundawat and Qureshi 1999, Raghavan and Bhatnagar 2002). Pressure from increased livestock grazing is one of the major threats faced by the species today (Shackleton 1997, Fox et al. 1991, Mallon 1983, IUCN Red List 2000 Chundawat and Qureshi 1999, Raghavan and Bhatnagar 2003). In the impoverished habitat provided by the Trans-Himalayas, there is great competition for the scarce resources between various animal species surviving here (Fox 1996, Mishra 2001). The presence of livestock intensifies this competition and can either force the species out of its niche (competitive exclusion) by displacing it from that area or resource, or lead to partitioning of resources between the species, spatially or temporally, for coexistence (Begon et al. 1986, Gause 1934).
