Title Pastoralism in the high Himalayas: Pastoralism: Research, Policy and Practice Open Access Understanding changing practices and their implications for parasite transmission between livestock and wildlife Type Journal Article
Year 2022 Publication Springer Open Abbreviated Journal
Volume 12 Issue 44 Pages 1-16
Keywords Migratory, Transhumance, Livestock, Asiatic ibex, Capra sibirica, Pasture, Rangelands, Gastro-intestinal nematodes
Abstract Rangelands are increasingly being affected by climatic variations, fragmentation and changes in livestock management practices. Along with resource competition between livestock and wildlife, disease transmission has implications for people and wildlife in these shared landscapes. We worked with two pastoral communities in the Western Indian Himalayas: the migratory Kinnauras that travel to the Trans‐Himalayan Pin valley in summer and the resident herders of Pin Valley. Asiatic ibex (Capra sibirica) is the predominant wild herbivore in Pin. The pastures in Pin are grazed by both livestock (migratory and resident) and ibex, with the potential for disease transmission. We investigate the effects of herding practices on livestock health and disease transmission, while focusing on gastro‐intestinal nematodes (GINs) as they can spread by sharing pasture between wild and domestic ungulates. Surveys were carried out between June and August 2019, the period when migratory Kinnauras, local herders and Asiatic Ibex are found in Pin Valley. We found that the Kinnaura flocks share pasture with ibex during their time in Pin, exhibiting significantly higher endo‐parasite burdens than sedentary livestock, and the Kinnaura flocks are increasing in number. This suggests GIN cross‐transmission is possible, as GINs have low host specificity and a free‐living, environmental stage that is trophically acquired. As local (sedentary) sheep and goats rarely share pasture with ibex, have low endo‐parasite burdens and are few in number, they are unlikely to transmit parasites to ibex. However, increasingly large local stock numbers may be contributing to pasture degradation which could cause nutritional stress and resource competition, exacerbating GIN impacts. We also find evidence for transhumance persisting, in spite of signs of pasture degradation that are seemingly affecting livestock productivity and potentially disease transmission. It is critical that proactive measures are taken, like participatory disease management with the Kinnauras, to align livelihoods with wildlife and rangeland conservation.

Title Predicting Parasite Dynamics in Mixed-Use Trans-Himalayan Pastures to Underpin Management of Cross-Transmission Between Livestock and Bharal Type Journal Article
Year 2021 Publication Frontiers in Veterinary Science Abbreviated Journal
Volume 8 Issue 714241 Pages 1 - 21
Keywords disease, Trans-Himalaya, livestock, nematodes, bharal, model, ungulates, grazing
Abstract The complexities of multi-use landscapes require sophisticated approaches to addressing disease transmission risks. We explored gastro-intestinal nematode (GINs) infections in the North India Trans-Himalayas through a socio-ecological lens, integrating parasite transmission modelling with field surveys and local knowledge, and evaluated the likely effectiveness of potential interventions. Bharal (blue sheep; Pseudois nayaur), a native wild herbivore, and livestock share pasture year-round and livestock commonly show signs of GINs infection. While both wild and domestic ungulates had GINs infections, egg counts indicated significantly higher parasite burdens in bharal than livestock. However, due to higher livestock densities, they contributed more to the total count of eggs and infective larvae on pasture. Herders also reported health issues in their sheep and goats consistent with parasite infections. Model simulations suggested that pasture infectivity in this system is governed by historical pasture use and gradually accumulated larval development during the summer, with no distinct short-term flashpoints for transmission. The most effective intervention was consequently predicted to be early-season parasite suppression in livestock using temperature in spring as a cue. A 1-month pause in egg output from livestock could lead to a reduction in total annual availability of infective larvae on pasture of 76%, potentially benefitting the health of both livestock and bharal. Modelling suggested that climate change over the past 33 years has led to no overall change in GINs transmission potential, but an increase in the relative influence of temperature over precipitation in driving pasture infectivity. Our study provides a transferable multi-pronged approach to investigating disease transmission, in order to support herders’ livelihoods and conserve wild ungulates.

Title Understanding population baselines: status of mountain ungulate populations in the Central Tien Shan Mountains, Kyrgyzstan Type Journal Article
Year 2020 Publication Mammalia Abbreviated Journal
Volume Issue Pages 1-8
Keywords conservation; human-use landscapes; hunting concession; mountain ungulates; population baselines; protected areas.
Abstract We assessed the density of argali (Ovis ammon) and ibex

(Capra sibirica) in Sarychat-Ertash Nature Reserve and its neighbouring

Koiluu valley. Sarychat is a protected area, while Koiluu is a human-use

landscape which is a partly licenced hunting concession for mountain

ungulates and has several livestock herders and their permanent

residential structures. Population monitoring of mountain ungulates can

help in setting measurable conservation targets such as appropriate

trophy hunting quotas and to assess habitat suitability for predators

like snow leopards (Panthera uncia). We employed the double-observer

method to survey 573 km2 of mountain ungulate habitat inside Sarychat

and 407 km2 inside Koiluu. The estimated densities of ibex and argali in

Sarychat were 2.26 (95% CI 1.47–3.52) individuals km-2 and 1.54 (95% CI

1.01–2.20) individuals km-2, respectively. Total ungulate density in

Sarychat was 3.80 (95% CI 2.47–5.72) individuals km-2. We did not record

argali in Koiluu, whereas the density of ibex was 0.75 (95% CI

0.50–1.27) individuals km-2. While strictly protected areas can achieve

high densities of mountain ungulates, multi-use areas can harbour

meaningful

though suppressed populations. Conservation of mountain ungulates and

their predators can be enhanced by maintaining Sarychat-like “pristine”

areas interspersed within a matrix of multi-use areas like Koiluu.

Title Climate casualties or human disturbance? Shrinking distribution of the three large carnivores in the Greater Himalaya Type Journal Article
Year 2023 Publication Springer – Climatic Change Abbreviated Journal
Volume 176 Issue 118 Pages 1-17
Keywords Snow leopard · Common leopard · Asiatic black bear · Climate change · Multi- season occupancy analysis · Local ecological knowledge · Imperfect detection
Abstract Mammalian carnivores are key to our understanding of ecosystem dynamics, but most of them are threatened with extinction all over the world. Conservating large carnivores is often an arduous task considering the complex relationship between humans and carnivores, and the diverse range and reasons of threats they face. Climate change is exacerbating the situation further by interacting with most existing threats and amplifying their impacts. The Mountains of Central and South Asia are warming twice as rapidly as the rest of the northern hemisphere. There has been limited research on the effect of climate change and other variables on large carnivores. We studied the patterns in spatio-temporal distribution of three sympatric carnivores, common leopard, snow leopard, and Asiatic black bear in Kishtwar high altitude National Park, a protected area in the Great Himalayan region of Jammu and Kashmir. We investigated the effects of key habitat characteristics as well as human disturbance and climatic factors to understand the spatio-temporal change in their distributions between the early 1990s and around the year 2016–2017. We found a marked contraction in the distribution of the three carnivores between the two time periods. While snow leopard shifted upwards and further away from human settlements, common leopard and Asiatic black bear suffered higher rates of local extinctions at higher altitudes and shifted to lower areas with more vegetation, even if that brought them closer to settlements. We also found some evidence that snow leopards were less likely to have faced range contraction in areas with permanent glaciers. Our study underscores the importance of climate adaptive conservation practices for long-term management in the Greater Himalaya, including the monitoring of changes in habitat, and space-use patterns by human communities and wildlife.

Title Seasonal Prey Abundance and Food Plasticity of the Vulnerable Snow Leopard (Panthera uncia) in the Lapchi Valley, Nepal Himalayas Type 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 First camera-trap record of the snow leopard Panthera uncia in Gaurishankar Conservation Area, Nepal Type Journal Article
Year 2020 Publication Oryx Abbreviated Journal
Volume Issue Pages 1-4
Keywords Camera trap, corridor, Gaurishankar Conser- vation Area, Nepal, Panthera uncia, prey abundance, transboundary, snow leopard
Abstract The snow leopard Panthera uncia is the flagship species of the high mountains of the Himalayas. There is po- tentially continuous habitat for the snow leopard along the northern border of Nepal, but there is a gap in information about the snow leopard in Gaurishankar Conservation Area. Previous spatial analysis has suggested that the Lamabagar area in this Conservation Area could serve as a transbound- ary corridor for snow leopards, and that the area may con- nect local populations, creating a metapopulation. However, there has been no visual confirmation of the species in Lamabagar. We set !! infrared camera traps for " months in Lapchi Village of Gaurishankar Conservation Area, where blue sheep Pseudois nayaur, musk deer Moschus leucogaster and Himalayan tahr Hemitragus jemlahicus, all snow leopard prey species, had been observed. In November #$!% at &,!$$ m, ' km south-west of Lapchi Village, one camera recorded three images of a snow leopard, the first photographic evidence of the species in the Conservation Area. Sixteen other species of mammals were also recorded. Camera-trap records and sightings indicated a high abun- dance of Himalayan tahr, blue sheep and musk deer. Lapchi Village may be a potentially important corridor for snow leopard movement between the east and west of Nepal and northwards to Quomolongma National Park in China. However, plans for development in the region present in- creasing threats to this corridor. We recommend develop- ment of a transboundary conservation strategy for snow leopard conservation in this region, with participation of Nepal, China and international agencies.

Title Large-scale and fine-grain population structure and genetic diversity of snow leopards (Panthera uncia Schreber, 1776) from the northern and western parts of the range with an emphasis on the Russian population. Type Journal Article
Year 2021 Publication Conservation Genetics Abbreviated Journal
Volume Issue Pages
Keywords Snow leopard, Panthera uncia, Microsatellites, Heterozygosity, Population structure, Noninvasive survey, Scat, Subspecies
Abstract The snow leopard (Panthera uncia Schreber, 1776) population in Russia and Mongolia is situated at the northern edge of the range, where instability of ecological conditions and of prey availability may serve as prerequisites for demographic instability and, consequently, for reducing the genetic diversity. Moreover, this northern area of the species distribution is connected with the western and central parts by only a few small fragments of potential habitats in the Tian-Shan spurs in China and Kazakhstan. Given this structure of the range, the restriction of gene flow between the northern and other regions of snow leopard distribution can be expected. Under these conditions, data on population genetics would be extremely important for assessment of genetic diversity, population structure and gene flow both at regional and large-scale level. To investigate large-scale and fine-grain population structure and levels of genetic diversity we analyzed 108 snow leopards identified from noninvasively collected scat samples from Russia and Mongolia (the northern part of the range) as well as from Kyrgyzstan and Tajikistan (the western part of the range) using panel of eight polymorphic microsatellites. We found low to moderate levels of genetic diversity in the studied populations. Among local habitats, the highest heterozygosity and allelic richness were recorded in Kyrgyzstan (He = 0.66 ± 0.03, Ho = 0.70 ± 0.04, Ar = 3.17) whereas the lowest diversity was found in a periphery subpopulation in Buryatia Republic of Russia (He = 0.41 ± 0.12, Ho = 0.29 ± 0.05, Ar = 2.33). In general, snow leopards from the western range exhibit greater genetic diversity (He = 0.68 ± 0.04, Ho = 0.66 ± 0.03, Ar = 4.95) compared to those from the northern range (He = 0.60 ± 0.06, Ho = 0.49 ± 0.02, Ar = 4.45). In addition, we have identified signs of fragmentation in the northern habitat, which have led to significant genetic divergence between subpopulations in Russia. Multiple analyses of genetic structure support considerable genetic differentiation between the northern and western range parts, which may testify to subspecies subdivision of snow leopards from these regions. The observed patterns of genetic structure are evidence for delineation of several management units within the studied populations, requiring individual approaches for conservation initiatives, particularly related to translocation events. The causes for the revealed patterns of genetic structure and levels of genetic diversity are discussed.

Title Snow leopard (Panthera uncia) predation and consumption of an adult yak in the Mongolian Altai. Type Note
Year 2021 Publication Ethology Ecology & Evolution Abbreviated Journal EEE
Volume Issue Pages 1-8
Keywords
Abstract The snow leopard (Panthera uncia) is an apex predator of mountainous ecosystems in Central Asia, characterised by relatively long feeding times and low kill rates (Johansson et al. 2015; Mallon et al. 2016). Predation is mainly focused on wild ungulates and the vast majority of animals killed by snow leopards are smaller than 100 kg (Lovari et al. 2013). Throughout most of their range, Siberian ibex (Capra sibirica), blue sheep (Pseudois nayaur), and argali (Ovis ammon) represent the most important prey (Hunter 2015). These species weigh up to 180 kg, which was suggested to be near the maximum limit of the prey size that snow leopard can handle (i.e. about 3 times its size) (e.g. Schaller 1977; Hunter 2015). Accordingly, researchers generally assume that prey like adult yaks (Bos grunniens) with an average body weight of 250 kg (Bagchi & Mishra 2006), are too large to be killed by snow leopards (e.g. Devkota et al. 2013; Chetri et al. 2017). In contrast, local livestock herders report that snow leopard can also kill larger prey, including adult yaks (e.g. Li et al. 2013; Suryawanshi et al. 2013), but confirmed records of snow leopard killing prey of this size appear to be lacking in the literature. We also have very limited knowledge about the consumption of snow leopard kills, and the scavengers, including conspecifics, that are using them (Fox & Chundawat 2016; Schaller 2016). Here we report on a predation event and the following consumption process of a snow leopard kill, a free-roaming adult female yak, which we studied in 2019 using snow tracking, direct observation and camera trapping in the Mongolian Altai.

Title Studying the snow leopard: reconceptualizing conservation across the China–India border Type Journal Article
Year 2016 Publication British Journal for the History of Science Abbreviated Journal BJHS
Volume Themes 1 Issue 1 Pages 169-198
Keywords
Abstract The snow leopard is a highly charismatic megafauna that elicits admiration, concern and donations from individuals and NGOs in the West. In its home territories, however, it is a threat to local communities’ livestock and a potential source of income for its pelt and parts. Conservation and study are further challenged by its range; snow leopards traverse the borders separating China, India and ten other countries with long histories of tension with each other as well as internal political and economic struggles. This transnational animal provides an ideal case study for the consideration of transnational conservation science in the recent past.

Title Analysis of Conservation Gaps and Landscape Connectivity for Snow Leopard in Qilian Mountains of China Type Journal Article
Year 2022 Publication Sustainability Abbreviated Journal 1-13
Volume 14 Issue 1638 Pages
Keywords national park; protection gap; landscape connectivity; habitat suitability
Abstract Human modification and habitat fragmentation have a substantial influence on large carnivores, which need extensive, contiguous habitats to survive in a landscape. The establishment of protected areas is an effective way to offer protection for carnivore populations by buffering them from anthropogenic impacts. In this study, we used MaxEnt to model habitat suitability and to identify conservation gaps for snow leopard (Panthera uncia) in the Qilian Mountains of China, and then assessed the impact of highways/railways and their corridors on habitat connectivity using a graph-based landscape connectivity model. Our results indicated that the study area had 51,137 km2 of potentially suitable habitat for snow leopards and that there were four protection gaps outside of Qilian Mountain National Park. The findings revealed that the investigated highway and railway resulted in a decrease in connectivity at a regional scale, and that corridor development might enhance regional connectivity, which strengthens the capacity of central habitat patches to act as stepping stones and improve connections between western and eastern habitat patches. This study emphasized the need for assessing the impact of highways and railways, as well as their role in corridor development, on species’ connectivity. Based on our results, we provide some detailed recommendations for designing protection action plans for effectively protecting snow leopard habitat and increasing habitat connectivity.
