  Title Determining the composition of herbivore diets in the Trans-Himalayan rangelands: A comparison of field methods Type Journal Article
  Year 2006 Publication (up) Journal of Rangeland Ecology and Management Abbreviated Journal  
  Volume 59 Issue 5 Pages 512-518  
  Keywords bite count; Bos grunniens; Capra hircus; diet; fecal analysis; feeding site examination; food habits; free ranging; Nepal; Ovis aries; trans-himalayan  
  Abstract In late summer, in a semi-arid mountain range in Nepal, we compared 3 field methods for determining the botanical composition of herbivore diets. Data were collected from the same animals belonging to 1 herd of domestic yak (Bos grunniens) and 2 herds of mixed smallstock, consisting of domestic goats (Capra hircus) and sheep (Ovis aries). Bite count, feeding site examination, and microhistological analysis of feces gave different estimates of forage categories and plant species in both animal groups. Because yaks grazed in other vegetation communities when not observed for bite-counts and feeding signs, the results from the latter methods could not be compared directly with that from fecal analysis. In smallstock, feeding site examination gave higher estimates of graminoids and lower estimates of shrubs than the other 2 methods, probably because all feeding signs on shrubs were not detected. Bite-counts and fecal analysis gave comparable results, except that forbs were underestimated by fecal analysis, presumably due to their more complete digestion. Owing to the difficulty in collecting samples that are representative of the entire grazing period and the problem of recording feeding signs correctly, both feeding site examination and bite-counts are unsuitable methods for studying the food habits of free ranging domestic and wild herbivores. Microhistological analysis of feces appears to be the most appropriate method, but correction factors are needed to adjust for differential digestion. The systematic use of photomicrographs improves the speed and accuracy of the fecal analysis.

  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 (up) Journal of Threatened Taxa Abbreviated Journal  
  Volume 11 Issue 7 Pages 13815-13821  
  Keywords 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 Summer diets of wild and domestic ungulates in Nepal Himalaya Type Journal Article
  Year 2005 Publication (up) Journal of Zoology Abbreviated Journal  
  Volume 266 Issue Pages 111-119  
  Keywords argali; blue sheep; Capra hircus; diet; faecal analysis; fecal analysis; mountain ungulates; Ovis ammon hodgsoni; pseudois nayaur  
  Abstract The selection of summer forage by three sympatric ungulates in the Damodar Kunda region of upper Mustang in

north Nepal was studied to assess the extent of food overlap between them. To compare their diets, a microhistological technique of faecal analysis was used, adjusted for inherent biases by comparing it with bite-count data obtained in domestic goats. Tibetan argali Ovis ammon hodgsoni, naur (blue sheep or bharal) Pseudois nayaur and domestic goat Capra hircus consumed mostly forbs, graminoids and browse, respectively. The proportions of food items in their diets were significantly different both at the plant species (P<0.02) and at the forage category level (P<0.001). Except for sharing three common plants (Agrostis sp., Stipa sp. and Potentilla fruticosa), dietary overlap at the species level was quite low. At the forage category level, naur and domestic goat overlapped more than the other ungulate pairs. Although all three species were opportunistic, mixed feeders, argali was a more selective forb specialist grazer than the other two ungulates. Owing to some spatial separation and little dietary overlap, interspecific competition for summer forage was low. If animal densities increase, however, goats are expected to compete more with naur than with argali because of their more similar diets. Owing to differences in forage selection by argali and naur throughout their large geographical ranges, reflecting adaptations to local ecological conditions, inferences regarding forage competition between domestic livestock and these two wild caprins need to be made from local, site-specific studies, rather than from general diet comparisons.

  Title A key for the identification of the hair of mammals of a snow leopard (Panthera uncia) habitat in Nepal Type Journal Article
  Year 1993 Publication (up) Journal of Zoology London Abbreviated Journal  
  Volume 231 Issue 1 Pages 71-93  
  Keywords Nepal; snow leopard; scats; Hair; diet; identification; Panthera-uncia; browse; panthera uncia; panthera; uncia; 780  
  Abstract Analysis of prey remains in scats, particularly hairs, in widely used to study diet of mammalian predators, but identification of hair is often difficult because hair structures vary considerably both within and between species. Use of photographic reference of diagnostically important hair structures from mammals occurring in a predator's habitat has been found to be convenient for routine identification. A photographic reference key was developed for the identification of hairs of the mammals known to occur in a snow leopard (Panthera uncia) habitat in the Annapurna Conservation Area, Nepal. The key included a photographic reference of the diagnostic hair structures of nine species of wild and five species of domestic mammals. The cross-sectional appearance, shape and arrangement of medulla, the ratio of cortex to medulla, and the form and distribution of pigment in medulla and cortex were important diagnostic aids in the identification of hairs.

  Title Diet of the snow leopard (Panthera uncia) in the Annapurna Conservation Area, Nepal Type Journal Article
  Year 1993 Publication (up) Journal of Zoology London Abbreviated Journal  
  Volume 231 Issue 3 Pages 365-370  
  Keywords predation; scats; prey; Nepal; blue-sheep; marmot; yaks; pika; livestock; diet; blue; sheep; browse; 770  
  Abstract The diet of the snow leopard (Panthera uncia) was studied from 213 scats collected between April 1990 and February 1991 in the Annapurna Conservation Area, Nepal. Seven species of wild and five species of domestic mammals were taken, as well as an unidentified mammal and birds. Blue sheep (Pseudois nayaur) were the most frequently eaten prey. Himalayan marmots (Marmota himalayana) were also important, except in winter when they were hibernating. During winter, snow leopards ate more Royle's pika (Ochotona roylei) and domestic livestock. Yaks were eaten more frequently than other livestock types.

  Title Why should a grazer browse? Livestock impact on winter resource use by bharal Pseudois nayaur Type Journal Article

  Abstract Many mammalian herbivores show a temporal diet variation between graminoid-dominated and browse dominated diets. We determined the causes of such a diet shift and its implications for conservation of a medium sized ungulate-the bharal Pseudois nayaur. Past studies show that the bharal diet is dominated by graminoids (>80%) during summer, but the contribution of graminoids declines to about 50% in winter. We tested the predictions generated by two alternative hypotheses explaining the decline: low graminoid availability during winter causes bharal to include browse in their diet; bharal include browse, with relatively higher nutritional quality, in their diet to compensate for the poor quality of graminoids during winter. We measured winter graminoid availability in areas with no livestock grazing, areas with relatively moderate livestock grazing, and those with intense livestock grazing pressures. The chemical composition of plants contributing to the bharal diet was analysed. The bharal diet was quantiWed through signs of feeding on vegetation at feeding locations. Population structures of bharal populations were recorded using a total count method. Graminoid availability was highest in areas without livestock grazing, followed by areas with moderate and intense livestock grazing. The bharal diet was dominated by graminoids (73%) in areas with highest graminoid availability. Graminoid contribution to the bharal diet declined monotonically (50, 36%) with a decline in graminoid availability. Bharal young to female ratio was 3 times higher in areas with high graminoid availability than areas with low graminoid availability. The composition of the bharal winter diet was governed predominantly by the availability of graminoids in the rangelands. Our results suggest that bharal include more browse in their diet during winter due to competition from livestock for graminoids. Since livestock grazing reduces graminoid availability, creation of livestock-free areas is necessary for the conservation of grazing species such as the bharal and its predators including the endangered snow leopard in the Trans-Himalaya.

  Title Relationship between ibex and snow leopard about food chain and population density in Tian Shan Type Journal Article
  Year 2015 Publication (up) Selevinia Abbreviated Journal  
  Volume Issue Pages 186-190  
  Keywords diet, ibex, snow leopard  
  Abstract Many studies have demonstrated that ibex (Capra sibirica) are the most frequently eaten prey of snow

leopards (Panthera uncia) in Xinjiang, the west of China. Thus, an understanding of interactions between these species may have significant management and conservation of implications for both. In this study, we provide information on ibex grouping and density over a 24 month period in the Tian Shan of Xinjiang, China. We then use ibex density to estimate the density of snow leopards. We observed ibex primarily in ewe-lamb groups (N=880), but ibex sexual segregation and grouping changed seasonally with more mixed-sex groups during the winter rut. We observed the most ibex in April 2014 and 2015 with an average of (2422 ± 119 ibex). Over the 1643 km2 study area we then estimated an ibex density of 154 ± 23 ibex /100 km2 from which we estimated a density of 1.31~2.58 snow leopards/100 km2.

  Title A Survey of Serum and Dietary Carotenoids in Captive Wild Animals Type Journal Article
  Year 1999 Publication (up) The Journal of Nutrition Abbreviated Journal  
  Volume 129 Issue Pages 380-390  
  Keywords captive; carotenoids; dietary; Serum; snow leopard; survey; wild; Animals; Animal  
  Abstract Accumulation of carotenoids varies greatly among animal species and is not fully characterized.

Circulating carotenoid concentration data in captive wild animals are limited and may be useful for their management.

Serum carotenoid concentrations and dietary intakes were surveyed and the extent of accumulation

categorized for 76 species of captive wild animals at Brookfield Zoo. Blood samples were obtained opportunistically

from 275 individual animals immobilized for a variety of reasons; serum was analyzed for a- and b-carotene,

lutein 1 zeaxanthin, lycopene, b-cryptoxanthin and canthaxanthin. Total carotenoid content of diets was calculated

from tables and chemical analyses of commonly consumed dietary components. Diets were categorized as

low, moderate or high in carotenoid content as were total serum carotenoid concentrations. Animals were

classified as unknown, high, moderate or low (non-) accumulators of dietary cartenoids. Nonaccumulators had total

serum carotenoid concentrations of 0-101 nmol/L, whereas accumulators had concentrations that ranged widely,

from 225 to 35,351 nmol/L. Primates were uniquely distinguished by the widest range of type and concentration

of carotenoids in their sera. Most were classified as high to moderate accumulators. Felids had high accumulation

of b-carotene regardless of dietary intake, whereas a wide range of exotic birds accumulated only the xanthophylls,

lutein 1 zeaxanthin, canthaxanthin or cryptoxanthin. The exotic ungulates, with the exception of the bovids, had

negligible or nondetectable carotenoid serum concentrations despite moderate intakes. Bovids accumulated only

b-carotene despite moderately high lutein 1 zeaxanthin intakes. Wild captive species demonstrated a wide variety

of carotenoid accumulation patterns, which could be exploited to answer remaining questions concerning carotenoid

metabolism and function.

  Title Diet selection of snow leopard (Panthera uncia) in Chitral, Pakistan Type Journal Article
  Year 2017 Publication (up) Turkish Journal of Zoology Abbreviated Journal  
  Volume Issue 14 Pages 914-923  
  Keywords Snow leopard, conservation, seasonal variation, diet composition, Chitral, Pakistan  
  Abstract Snow leopard (Panthera uncia) is an elusive endangered carnivore found in remote mountain regions of Central Asia, with

sparse distribution in northern Pakistan, including Chitral and Baltistan. The present study determined the food habits of snow leopard,

including preferred prey species and seasonal variation in diet. Fifty-six scat samples were collected and analyzed to determine the

diet composition in two different seasons, i.e. summer and winter. Hair characteristics such as cuticular scale patterns and medullary

structure were used to identify the prey. This evidence was further substantiated from the remains of bones, claws, feathers, and other

undigested remains found in the scats. A total of 17 prey species were identified; 5 of them were large mammals, 6 were mesomammals,

and the remaining 6 were small mammals. The occurrence of wild ungulates (10.4%) in the diet was low, while livestock constituted a

substantial part (26.4%) of the diet, which was higher in summer and lower in winter. Mesomammals altogether comprised 33.4% of

the diet, with palm civet (Paguma larvata) as a dominant (16.8%) species, followed by golden marmot (Marmota caudate) (8.8%), which

was higher in winter. There was a significant difference in seasonal variation in domestic livestock and small mammals. The livestock

contribution of 26.4% observed in the present study indicates a significant dependence of the population on livestock and suggests

that the study area is expected to be a high-conflict area for snow leopards. The results of the current study would help improve the

conservation efforts for snow leopards, contributing to conflict resolution and effective management of this endangered cat.

  Title Snow leopard Panthera uncia predation on livestock and wild prey in a mountain valley in northern Nepal: implications for conservation management Type Journal Article
  Year 2012 Publication (up) Wildlife Biology Abbreviated Journal  
  Volume 18 Issue 10.2981/11-049 Pages 131-141  
  Keywords bharal, blue sheep, diet, genetic sampling, naur, Panthera uncia, predation, Pseudois nayaur, scat analysis, snow leopard, wildlife conflict  
  Abstract The globally endangered snow leopard Panthera uncia is sparsely distributed throughout the rugged mountains in Asia.

Its habit of preying on livestock poses a main challenge to management. In the remote Phu valley in northern Nepal, we

obtained reliable information on livestock losses and estimated predator abundance and diet composition from DNA

analysis and prey remains in scats. The annual diet consisted of 42%livestock. Among the wild prey, bharal (blue sheep/

naur) Pseudois nayaur was by far the most common species (92%). Two independent abundance estimates suggested that

there were six snow leopards in the valley during the course of our study. On average, each snow leopard killed about one

livestock individual and two bharal permonth. Predation loss of livestock estimated fromprey remains in scats was 3.9%,

which was in concordance with village records (4.0%). From a total count of bharal, the only large natural prey in the area

and occurring at a density of 8.4 animals/km2 or about half the density of livestock, snow leopards were estimated to

harvest 15.1% of the population annually. This predation rate approaches the natural, inherent recruitment rate of this

species; in Phu the proportion of kids was estimated at 18.4%. High livestock losses have created a hostile attitude against

the snow leopard and mitigation measures are needed. Among innovative management schemes now being implemented

throughout the species’ range, compensation and insurance programmes coupled with other incentive measures are

encouraged, rather than measures to reduce the snow leopard’s access to livestock. In areas like the Phu valley, where the

natural prey base consists mainly of one ungulate species that is already heavily preyed upon, the latter approach, if

implemented, will lead to increased predation on this prey, which over time may suppress numbers of both prey and

predator.
