  Abstract An increasing proportion of the world�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�the preferred

prey�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 at

facilitating increases in wild prey must be accompanied by greater assistance for better livestock

protection and offsetting the economic damage caused by carnivores.

  Title Changes in ecological conditions may influence intraguild competition: inferring interaction patterns of snow leopard with co-predators Type Journal Article
  Year 2022 Publication (down) 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.

  Title Co-occurrence of snow leopard Panthera uncia, Siberian ibex Capra sibirica and livestock: potential relationships and effects Type Journal Article
  Year 2018 Publication (down) Oryx Abbreviated Journal  
  Volume Issue Pages 1-7  
  Keywords Altai mountains, camera trapping, human� wildlife conflict, Mongolia, occupancy, occurrence interactions, Siberian ibex, snow leopard  
  Abstract Understanding the impact of livestock on native

wildlife is of increasing conservation relevance. For the

Vulnerable snow leopard Panthera uncia, wild prey reduction,

intensifying human�wildlife conflicts and retaliatory

killings are severe threats potentially exacerbated by the

presence of livestock. Elucidating patterns of co-occurrence

of snow leopards, wild ungulate prey, and livestock, can be

used to assess the compatibility of pastoralism with conservation.

We used camera trapping to study the interactions of

livestock, Siberian ibex Capra sibirica and snow leopards in

a national park in the Altai mountains, Mongolia. We obtained

 detections of wild mammals and  of domestic

ungulates, dogs and humans. Snow leopards and Siberian

ibex were recorded  and  times, respectively. Co-occurrence

modelling showed that livestock had a higher estimated

occupancy (.) than ibex, whose occupancy was

lower in the presence of livestock (.) than in its absence

(.�. depending on scenarios modelled). Snow leopard

occupancy did not appear to be affected by the presence of

livestock or ibex but the robustness of such inference was

limited by uncertainty around the estimates. Although our

sampling at presumed snow leopard passing sites may have

led to fewer ibex detections, results indicate that livestock

may displace wild ungulates, but may not directly affect

the occurrence of snow leopards. Snow leopards could still

be threatened by livestock, as overstocking can trigger

human�carnivore conflicts and hamper the conservation

of large carnivores. Further research is needed to assess

the generality and strength of our results.

  Title Predator niche overlap and partitioning and potential interactions in the mountains of Central Asia Type Journal Article
  Year 2022 Publication (down) 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.

  Abstract Electroejaculates from eight snow leopards were used to determine how the motility of spermatozoa was influenced by (i) type of media (Ham's F10, PBS, human tubal fluid or RPMI-1640); (ii) holding temperature (23 degrees C versus 37 degrees C); (iii) washing of spermatozoa and (iv) a sperm metabolic enhancer, pentoxifylline. The duration of sperm motility was assessed by evaluating samples in each treatment every hour for 6 h and a sperm motility index (a value combining percentage sperm motility and rate of forward progression) calculated. Spermatozoa from the Ham's F10, PBS and PBS plus pentoxifylline treatments were also co-incubated with zona-intact, domestic cat eggs that were fixed and evaluated for spermatozoa bound to the zona pellucida, penetrating the outer and inner layers of the zona pellucida and within the perivitelline space. During the 6 h co-incubation, the sperm motility index in PBS with pentoxifylline was greater (P < 0.05) than in PBS alone which, in turn, was greater (P < 0.05) than in the other three test media. Washing the spermatozoa enhanced (P < 0.05) motility in both PBS and PBS plus pentoxifylline relative to unwashed samples, but there was no effect (P > 0.05) of holding temperature. Pentoxifylline supplementation enhanced (P < 0.05) the proportion of cat eggs with bound, but not penetrated, snow leopard spermatozoa in the inner layer of the zona pellucida, and there were no spermatozoa in the perivitelline space.(ABSTRACT TRUNCATED AT 250 WORDS)

  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 Effects of free-ranging livestock on occurrence and interspecific interactions of a mammalian community Type Journal Article
  Year 2022 Publication (down) Ecological-Applications. Abbreviated Journal  
  Volume Issue e2644 Pages 1-13  
  Keywords activity pattern, community occupancy, grassland, interspecific interactions, livestock encroachment, snow leopard  
  Abstract Mammalian communities inhabiting temperate grasslands are of conservation concern globally, especially in Central Asia, where livestock numbers have dramatically increased in recent decades, leading to overgrazing and land-use change. Yet, how this pervasive presence of livestock herds affects the community of wild mammals remains largely unstudied. We used systematic camera trapping at 216 sites across remote, mountainous areas of the Mongolian Altai Mountains to assess the spatial and temporal patterns of occurrence and the interspecific relationships within a mammalian community that includes different categories of livestock. By adopting a recently proposed multispecies occupancy model that incorporates interspecific correlation in occupancy, we found several statistically strong correlations in occupancy among species pairs, with the majority involving livestock. The sign of such associations was markedly species-dependent, with larger wild species of conservation concern, namely, snow leopard and Siberian ibex, avoiding livestock presence. As predicted, we found evidence of a positive correlation in occupancy between predators and their respective main prey. Contrary to our expectations, a number of intraguild species pairs also showed positive co-occurrence, with no evidence of spatiotemporal niche partitioning. Overall, our study suggests that livestock encroaching into protected areas influences the whole local community of wild mammals. Though pastoralism has coexisted with wildlife for millennia in central Asian grasslands, our findings suggest that policies and practices to decrease the pressure of livestock husbandry on wildlife are needed, with special attention on large species, such as the snow leopard and its wild prey, which seem to be particularly sensitive to this pervasive livestock presence.

  Title Predation may counteract climatic change as a driving force for movements of mountain ungulates Type Report
  Year 2016 Publication (down) 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.

  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.
