  Title Anti-predator strategies of blue sheep (naur) under varied predator compositions: a comparison of snow leopard-inhabited valleys with and without wolves in Nepal Type (up) Journal Article
  Year 2023 Publication Wildlife Research Abbreviated Journal  
  Volume Issue Pages 1-9  
  Keywords Annapurna conservation area, antipredator behavior, blue sheep (Naur), predation, prey predator traits, snow leopard, trade-off, wolf.  
  Abstract In Nepal, naur are usually the staple wild prey for the snow leopard, a solitary stalker hunter, and in some cases, for the wolf who hunts in a pack. We assumed that naur would adapt their anti-predatory responses to the presence of chasing and ambushing predators in the Manang Valley, where there are snow leopards and wolves, and in the Nar Phu valley, an area where there is only the snow leopard.

Aims. The aim of this study was to determine if there were differences in anti-predator strategies (vigilance, habitat selection and escape terrain) of naur in two valleys over two seasons, spring and autumn.

Methods. In spring 2019, we conducted a reconnaissance survey on the status of the naur and its habitat in the Manang and Nar Phu valleys of the Annapurna Conservation Area, Nepal. In spring and autumn 2020 and 2021, we observed 360 focal naur individuals (180 individuals in each valley), using the vigilance behaviour methodology to examine the behaviour of the naur.

Key results. There was little difference in the size of the naur groups between the Manang and Nar Phu valleys. The naur were twice as vigilant in Manang (15%), where there are snow leopards and wolves, as they were in Nar Phu (9%), with only snow leopards. The distance from the naur to escape cover was significantly shorter in Manang than in Nar Phu valley. Naur used significantly more rolling terrain in Nar Phu than in Manang. Conclusions. The return of wolves to the Manang valley may have resulted in an increase in the level of naur vigilance. Most likely, the wolves in Manang have already had an effect on the female-to-young-ratio, and this effect will possibly have important consequences for the naur population, as well as at the ecosystem level in the future. Other key determining factors, such as the climate crisis and changes in local resources, could have a significant impact on the naur population, indicating the need for more research. Implications. The findings of this study would provide valuable baseline information for the design of a science-based conservation strategy for conservation managers and scientists on naur, snow leopards and wolves.

  Title Seasonal Prey Abundance and Food Plasticity of the Vulnerable Snow Leopard (Panthera uncia) in the Lapchi Valley, Nepal Himalayas Type (up) Journal Article
  Year 2023 Publication Animals Abbreviated Journal  
  Volume 13 Issue 3182 Pages 1-16  
  Keywords apex predator; flagship species; micro-histology; niche overlap; prey preference  
  Abstract Conservation strategies for apex predators, like the snow leopard (Panthera uncia), depend on a robust understanding of their dietary preferences, prey abundance, and adaptability to changing ecological conditions. To address these critical conservation concerns, this study presents a comprehensive evidence on prey availability and preferences for snow leopards in the Lapchi Valley in the Nepal Himalayas from November 2021 to March 2023. Field data were collected through the installation of twenty-six camera traps at 16 strategically chosen locations, resulting in the recording of 1228 events of 19 mammalian species, including domesticated livestock. Simultaneously, the collection of twenty snow leopard scat samples over 3800 m above sea level allowed for a detailed dietary analysis. Photo capture rate index and biomass composition analysis were carried out and seasonal prey availability and consumption were statistically analyzed. A total of 16 potential prey species for the snow leopard were documented during the study period. Himalayan musk deer (Moschus leucogaster) was the most abundant prey species, but infrequent in the diet suggesting that are not the best bet prey for the snow leopards. Snow leopards were found to exhibit a diverse diet, consuming eleven prey species, with blue sheep (Pseudois nayaur) being their most consumed wild prey and horses as their preferred livestock. The Pianka’s index of dietary niche overlap between the summer and winter seasons were 0.576, suggesting a pronounced seasonal variation in food preference corroborating with the prey availability. The scarcity of larger preys in winter is compensated by small and meso-mammals in the diet, highlighting the snow leopard’s capacity for dietary plasticity in response to the variation in resource availability. This research suggests for the utilization of genetic tools to further explore snow leopard diet composition. Additionally, understanding transboundary movements and conducting population assessments will be imperative for the formulation of effective conservation strategies.

  Title Siberian ibex Capra sibirica Pall Type (up) Miscellaneous
  Year 1969 Publication Abbreviated Journal  
  Volume Issue Pages 98-105  
  Keywords Kyrgyzsatn; Siberian ibex; distribution; life history; diet; predators; snow leopard.; 5890; Russian  
  Abstract It describes status of ibex in Kyrgyzstan, its distribution, behavioral patterns, enemies and competitors, etc. The enemies of ibex are snow leopard and wolf. All year round snow leopard preys on ibex its main food object and, therefore, should there be ibexes, snow leopards would be somewhere around. In winter, a considerable number of ibex dies from wolves. Sometimes dogs prey on ibex, too. Golden eagles and bearded vultures prey on young ibexes. However, poachers remain the most dangerous enemy.

  Title Reappraisal of the role of big, fierce predators Type (up) Miscellaneous
  Year 2008 Publication Biodiversity Conservation Abbreviated Journal  
  Volume Issue Pages 685-690  
  Keywords Biodiversity ú Conservation ú Costs of predation ú Indirect effects ú Non-lethal effects ú Predators ú Top-down control; big; predators; predator  
  Abstract The suggestion in the early 20th century that top predators were a necessary component of ecosystems because they hold herbivore populations in check and promote biodiversity was at Wrst accepted and then largely rejected. With the advent of Evolutionary Ecology and a more full appreciation of direct and indirect effects of top predators, this role of top predators is again gaining acceptance. The previous views were predicated upon lethal effects of predators but largely overlooked their non-lethal effects. We suggest that

conceptual advances coupled with an increased use of experiments have convincingly demonstrated that prey experience costs that transcend the obvious cost of death. Prey species use adaptive behaviours to avoid predators, and these behaviours are not cost-free. With predation risk, prey species greatly restrict their use of available habitats and consumption of available food resources. Effects of top predators consequently cascade down to the trophic levels below them. Top predators, the biggies, are thus both the targets of and the means for conservation at the landscape scale.

  Title The contingencies of group size and vigilance Type (up) 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 Large predators of the Kazakhstan Altai and their importance for hunting industry Type (up) Miscellaneous
  Year 2002 Publication Abbreviated Journal  
  Volume Issue Pages 79-81  
  Keywords Kazakhstan; Altai; large predators; snow leopard; distribution; number; preys.; 6110; Russian  
  Abstract Fauna of large predatory mammals in the Kazakhstan Altai is represented by five species: wolf, bear, glutton, lynx, and snow leopard. Snow leopard inhabits the Sarymsakty and Tarbagai ridges and South Altai. This species is observed to regularly penetrate into the Kutun and Kurchum ridges. Its habitat covers an area of 1,800 sq. km, its population being 14-16 animals. The population density is 0.7 1.0 animals per 100 sq. km. A hunting area of a female animal with two cubs is 45 85 sq. km; a male 120 sq. km. Snow leopard main preys on ibex (41.1 percent), roe-deer (31.0 percent), and moral (13.8 percent); in summer on gray marmot (28.6 percent). Snow leopard is also known to prey on hares, birds, argali, and elks.
