| Title | Canine morphology in the larger Felidae: implications for feeding ecology | Type | Journal Article | ||

| Abstract | Canine morphology is analysed at seven intervals along the crown in both anteroposterior and lateromedial perspective in seven species of large felids. The puma and the snow leopard have stout, rather conical canines, whereas those of lions, jaguars, and tigers bear substantial resemblance to each other, reflecting their phylogenetic relationships, and are less conical and large. The canines of the leopard are intermediate in morphology between those of the other species, probably reflecting its more generalized diet. The clouded leopard has very large and blade-like canines, which are different from the other analysed species. Canine bending strengths to estimated bite forces appear to differ less among the species than morphology,indicating that the evolution of canines has been constricted with respect to their strength in failure, probably owing to their being equally important for species fitness. However, the clouded leopard again stands out, having a high estimated bite force and rather weak canines in bending about the anteroposterior as well as lateromedial planes compared to the other species. Canine morphology to some extent reflects differences in killing mode, but also appears to be related to the phylogeny. The marked divergence of the clouded leopard is presently not understood. |

| Title | Vigilance behaviour of the Tibetan argali Ovis ammon hodgsoni in the Indian Trans-Himalaya | Type | Journal Article | ||
| Year | 2007 | Publication | Acta Zoologica Sinica | Abbreviated Journal | |
| Volume |

| Keywords | Tibertan argali, Ovis ammon, vigilance, dilution effect, Ladakh, Trans-Himalaya | ||||
| Abstract | An inverse relationship between individual vigilance level and group size is widely reported in many behavioral studies on animals across several taxa. It is generally held that such a relationship is due to a reduced probability of an individual being killed in larger groups. in the present investigation, I studied the vigilance behavior of the endangered Tibetan argali Ovis ammon hodgsoni in relation to group size and escape terrain. I hypothesized that an individual argali has a higher vigilance level in smaller groups and in habitats closer to cliffs than individuals living in larger groups and open areas (escape terrain). The results show that the vigilance of argali decreased with increasing group size, but there was no effect of escape terrain on its vigilance behavior. There were significant differences between age-sex groups: male, female and yearling in their time budgets. Females, compared to males and yearlings, spent more time being vigilant. They also foraged more and moved less than males. It is suggested that vigilance is an important anti-predator behavior amongst argali sheep. | ||||

| Abstract | Snow leopards (Uncia uncia) are highly cryptic and occupy remote inaccessible habitat, making studying the cats difficult in the extreme. Yet sound knowledge of the cat's ecology, behavior and habitat needs is required to intelligently conserve them. This information is lacking for snow leopards, and until recently so was the means to fill that knowledge gap. Two long-term studies of snow leopards using VHF radio collars have been undertaken in Nepal (1980s) and Mongolia (1990s) but logistical and technological constraints made the findings of both studies equivocal. Technological advances in the interim, such as GPS collars which report data via satellite, make studies of snow leopards more promising, at least in theory. | ||||

| Abstract | From September to November 2004 we conducted surveys of snow leopard Uncia uncia signs in three major valleys in Sagarmatha (Mount Everest) National Park in Nepal using the Snow Leopard Information Management System, a standardized survey technique for snow leopard research. We walked 24 transects covering c. 14 km and located 33 sites with 56 snow leopard signs, and 17 signs incidentally in other areas. Snow leopards appear to have re-inhabited the Park, following their disappearance c. 40 years ago, apparently following the recovery of Himalayan tahr Hemitragus jemlahicus and musk deer Moschus chrysogaster populations. Taken together the locations of all 73 recent snow leopard signs indicate that the species is using predominantly grazing land and shrubland/ open forest at elevations of 3,000-5,000 m, habitat types that are also used by domestic and wild ungulates. Sagarmatha is the homeland of c. 3,500 Buddhist Sherpas with .3,000 livestock. Along with tourism and associated developments in Sagarmatha, traditional land use practices could be used to ensure coexistence of livestock and wildlife, including the recovering snow leopards, and ensure the wellbeing of the Sherpas. | ||||

| Title | Carnivore-Caused Livestock Mortality in Trans-Himalaya | Type | Miscellaneous | ||

| Keywords | Gya-Miru; livestock depredation; Lynx; snow leopard; trans-himalaya; wolf | ||||
| Abstract | The loss of livestock to wild predators is an important livelihood concern among Trans-Himalayan pastoralists. Because of the remoteness and inaccessibility of the region, few studies have been carried out to quantify livestock depredation by wild predators. In the present study, we assessed the intensity of livestock depredation by snow leopard Uncia uncia, Tibetan wolf Canis lupus chanku, and Eurasian lynx Lynx l. isabellina in three villages, namely Gya, Rumtse, and Sasoma, within the proposed Gya-Miru Wildlife Sanctuary in Ladakh, India. The three villages reported losses of 295 animals to these carnivores during a period of 2.5 years ending in early 2003, which represents an annual loss rate of 2.9% of their livestock holdings. The Tibetan wolf was the most important predator, accounting for 60% of the total livestock loss because of predation, followed by snow leopard (38%) and lynx (2%). Domestic goat was the major victim (32%), followed by sheep (30%), yak (15%), and horse (13%). Wolves killed horses significantly more and goats less than would be expected from their relative abundance. Snow leopards also killed horses significantly more than expected, whereas they killed other livestock types in proportion to their abundance. The three villages combined incurred an estimated annual monetary loss of approximately $USD 12,120 amounting to approximately $USD 190/household/y. This relatively high total annual loss occurred primarily because of depredation of the most valuable livestock types such as yak and horse. Conservation actions should initially attempt to target decrease of predation on these large and valuable livestock species. | ||||

| Title | Habitat shift and time budget of the Tibetan argali: the influence of livestock grazing | Type | Miscellaneous | ||
| Year | 2007 | Publication | Ecological Resources | Abbreviated Journal | |

| Keywords | habitat shift; livestock; Tibetan argali; Time budget; trans-himalaya | ||||
| Abstract | Livestock production is the primary source of livelihood and income in most of the high steppe and alpine regions of the Indian Trans-Himalaya. In some areas, especially those established or proposed for biodiversity conservation, recent increases in populations of domestic livestock, primarily sheep and goats, have raised concern about domestic animals competitively excluding wild herbivores from the rangelands. We evaluated the influence of domestic sheep and goat grazing on the habitat use and time budget of the endangered Tibetan argali Ovis ammon hodgsoni in the proposed Gya-Miru Wildlife Sanctuary, Ladakh, India. We asked if the domestic sheep and goat grazing and collateral human activities relegate the argali to suboptimal habitats, and alter their foraging time budgets. Data were collected on habitat use and time budget of a population of c. 50 argalis before and after c. 2,000 sheep and goats moved onto their winter pasture in the Tsabra catchment of the aforementioned reserve. Following the introduction of domestic sheep and goats, argalis continued to use the same catchment but shifted to steeper habitats, closer to cliffs, with lower vegetation cover, thus abandoning previously used plant communities with denser cover. Argalis' active time spent foraging also decreased by 10% in response to the presence of livestock. These results suggest a clear disturbance effect of livestock on argalis, and indicate a potential for competition, conceivably a significant disadvantage for argalis in winter when forage availability is minimal. |

| Abstract | The snow leopard and it s p rey were investigated in Beita Mountain Region , Xinjiang in Sep . 2004. Both the field survey and questionnaire were involved in this project which was supported by the International Snow Leopard Trust and Xinjiang Conservation Fund. The signs marked by the snow leopard were used to reflect the living condition of snow leopard and they were collected by running transects. The prey investigation was conducted by positioned observation and route survey. Fifteen transects were done in the project and 67 signs leaved by snow leopard were discovered in total. 58. 2 % of them were scrapes , 35.8 % of t hem were feces , 4.5 % of them were claw rakes and 1. 5 % of them were scent spray. As to the prey resources , 4 herds of 23 ibex and 24 herds of 418 chukars were found during the survey. Also 81 local people of 5 different nationalities were interviewed during the field work , 13. 58 % of them had seen the snow leopard , 20. 99 % of them had heard of snow leopard but not seen. Among t hem , 10 herdsmen had sufferred from the loss of livestock attacked by snow leopard. |

| Abstract | The merits of integrated conservation and development projects (ICDPs), which aim to provide development incentives to citizens in return for conservation behaviors, have long been debated in the literature. Some of the most common critiques suggest that conservation activities tend to be strongly overpowered by development activities. We studied this assertion through participant observation and archival analysis of five Conservation Area Management Committees (CAMCs) in the Annapurna Conservation Area (ACA), Nepal. Committee activities were categorized as conservation activities (policy development and conservation implementation), development activities (infrastructure, health care, education, economic development, and sanitation), or activities related to institutional strengthening (administrative development and capacity building activities). Greater longevity of each ICDP was associated with greater conservation activity in relation to development activities. Project life cycles progressed from a focus on development activities in their early stages, through a transitional period of institutional strengthening, and toward a longer-term focus that roughly balanced conservation and development activities. Results suggest that the ICDP concept, as practiced in ACA, has been successful at building capacity for and interest in conservation amongst local communities. However, success has come over a period of nearly a decade, suggesting that prior conclusions about ICDP failures may have been based on unrealistic expectations of the time needed to influence behavioral changes in target populations. | ||||

| 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. |

| Abstract | The snow leopard (Uncia uncia) is a rare carnivore living above the snow line in central Asia. Using universal primers for the mitochondrial genome control region hypervariable region 1 (HVR1), we isolated a 411-bp fragment of HVR1 and then designed specific primers near each end of this sequence in the conserved regions. These primers were shown to yield good polymerase chain reaction products and to be species specific. Of the 12 snow leopards studied, there were 11 segregating sites and six haplotypes. An identification case of snow leopard carcass (confiscated by the police) proved the primers to be a useful tool for forensic diagnosis in field and population genetics studies. |
