Title Effects of free-ranging livestock on occurrence and interspecific interactions of a mammalian community Type Journal Article
Year 2022 Publication Ecological-Applications. Abbreviated Journal
Volume Issue e2644 Pages 1-13
Keywords (up) 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 Co-occurrence of snow leopard Panthera uncia, Siberian ibex Capra sibirica and livestock: potential relationships and effects Type Journal Article
Year 2018 Publication Oryx Abbreviated Journal
Volume Issue Pages 1-7
Keywords (up) 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 Kleptoparasitic interaction between Snow Leopard Panthera uncia and Red Fox Vulpes vulpes suggested by circumstantial evidence in Pin Valley National Park, India Type Journal Article
Year 2022 Publication Journal of Threatened Taxa Abbreviated Journal
Volume 14 Issue 10 Pages 21928-21935
Keywords (up) Animal interaction, carnivore, mammals, prey, Trans-Himalaya.
Abstract In the present study, we describe an interspecific kleptoparasitic interaction between two sympatric mammalian carnivores in the high altitudinal Trans-Himalaya region of Himachal Pradesh, India. The study was based on the inferences drawn from the circumstantial evidence (direct and indirect) noticed in the study area in Pin Valley National Park. The inferences from the analysis of the evidence suggested the interaction between a Snow Leopard Panthera uncia, a Red Fox Vulpes vulpes, and a donkey. The arrangement of evidence in a sequential manner suggested that a donkey was killed by a Snow Leopard and a Red Fox stole the food from the carrion of the Snow Leopard’s prey. The Red Fox was killed by the Snow Leopard, which was caught while stealing. The present study represents an example of kleptoparasitic interaction between the Snow Leopard and the Red Fox. This study also proves that such interactions may cost the life of a kleptoparasite and supports the retaliation behaviour of Snow Leopards.

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)

Title Impact of wild prey availability on livestock predation by snow leopards Type Journal Article

Volume Issue Pages 1-11
Keywords (up) 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.

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

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

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 (up) 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 Cats, canines, and coexistence: dietary differentiation between the sympatric Snow Leopard and Grey Wolf in the western landscape of Nepal Himalaya Type Journal Article
Year 2019 Publication Journal of Threatened Taxa Abbreviated Journal
Volume 11 Issue 7 Pages 13815-13821
Keywords (up) Canis lupus, dietary pattern, dietary overlap, livestock, Naur, negative interaction, Panthera uncia, scat analysis, sympatry
Abstract Understanding the dietary habits of sympatric apex carnivores advances our knowledge of ecological processes and aids their conservation. We compared the diets of the sympatric Snow Leopard Panthera uncia and Grey Wolf Canis lupus using standard micro-histological analyses of scats collected from the western complex of Nepal Himalaya. Our study revealed one of the highest recorded contributions of livestock to the diet of top predators (55% for Grey Wolf and 39% for Snow Leopard) and high dietary overlap (0.82) indicating potential exploitative or interference competition. Their diet composition, however, varied significantly based on their consumption of wild and domestic prey. Limitation in data precludes predicting direction and outcome of inter-specific interactions between these predators. Our findings suggest a high rate of negative interaction with humans in the region and plausibly retaliatory killings of these imperilled predators. To ensure the sustained survival of these two apex carnivores, conservation measures should enhance populations of their wild prey species while reducing livestock losses of the local community through preventive and mitigative interventions.

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 (up) 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.

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 (up) 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.
