Title Estimating Snow Leopard Population Abundance Using Photography and Capture-Recapture Techniques Type Miscellaneous
Year 2006 Publication Wildlife Society Bulletin Abbreviated Journal
Volume 34 Issue 3 Pages (down) 772-781
Keywords abundance; camera trapping; capture rates; dentistry; identification; India; photography; snow leopard; Uncia uncia
Abstract Conservation and management of snow leopards (Uncia uncial) has largely relied on anecdotal evidence and presence-absence data due to their cryptic nature and the difficult terrain they inhabit. These methods generally lack the scientific rigor necessary to accurately estimate population size and monitor trends. We evaluated the use of photography in capture-mark-recapture (CMR) techniques for estimating snow leopard population abundance and density within Hemis National Park, Ladakh, India. We placed infrared camera traps along actively used travel paths, scent-sprayed rocks, and scrape sites within 16-30 kmý sampling grids in successive winters during January and March 2003-2004. We used head-on, oblique, and side-view camera configurations to obtain snow leopard photographs at varying body orientations. We calculated snow leopard abundance estimates using the program CAPTURE. We obtained a total of 66 and 49 snow leopard captures resulting in 8.91 and 5.63 individuals per 100 trap nights during 2003 and 2004, respectively. We identified snow leopards based on the distinct pelage patters located primarily on the forelimbs, flanks, and dorsal surface of the tail. Capture probabilities ranged from 0.33 to 0.67. Density estimates ranged from 8.49 (SE+0.22) individuals per 100 kmý in 2003 to 4.45 (SE+0.16) in 2004. We believe the density disparity between years is attributable to different trap density and placement rather than to an actual decline in population size. Our results suggest that photographic capture-mark-recapture sampling may be a useful tool for monitoring demographic patterns. However, we believe a larger sample size would be necessary for generating a statistically robust estimate of population density and abundance based on CMR models.

Title Comparison of noninvasive genetic and camera-trapping techniques for surveying snow leopards Type Journal Article
Year 2011 Publication Journal of Mammalogy Abbreviated Journal
Volume 92 Issue 4 Pages (down) 771-783
Keywords
Abstract The endangered snow leopard (Panthera uncia) is widely but sparsely distributed throughout the mountainous regions of central Asia. Detailed information on the status and abundance of the snow leopard is limited because of the logistical challenges faced when working in the rugged terrain it occupies, along with its secretive nature. Camera-trapping and noninvasive genetic techniques have been used successfully to survey this felid. We compared noninvasive genetic and camera-trapping snow leopard surveys in the Gobi Desert of Mongolia. We collected 180 putative snow leopard scats from 3 sites during an 8-day period along 37.74 km of transects. We then conducted a 65-day photographic survey at 1 of these sites, approximately 2 months after scat collection. In the site where both techniques were used noninvasive genetics detected 5 individuals in only 2 days of fieldwork compared to 7 individuals observed in the 65-day camera-trapping session. Estimates of population size from noninvasive genetics ranged between 16 and 19 snow leopards in the 314.3-km2 area surveyed, yielding densities of 4.9–5.9 individuals/100 km2. In comparison, the population estimate from the 65-day photographic survey was 4 individuals (adults only) within the 264-km2 area, for a density estimate of 1.5 snow leopards/100 km2. Higher density estimates from the noninvasive genetic survey were due partly to an inability to determine age and exclude subadults, reduced spatial distribution of sampling points as a consequence of collecting scats along linear transects, and deposition of scats by multiple snow leopards on common sites. Resulting differences could inflate abundance estimated from noninvasive genetic surveys and prevent direct comparison of densities derived from the 2 approaches unless appropriate adjustments are made to the study design.

Title Reappraisal of the role of big, fierce predators Type Miscellaneous
Year 2008 Publication Biodiversity Conservation Abbreviated Journal
Volume Issue Pages (down) 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 Globalization of the Cashmere Market and the Decline of Large Mammals in Central Asia Type Journal Article
Year Publication Conservation Biology Abbreviated Journal
Volume 27 Issue 4 Pages (down) 679-689
Keywords fashion, herders, India, Mongolia, saiga, trade
Abstract As drivers of terrestrial ecosystems, humans have replaced large carnivores in most areas, and

human influence not only exerts striking ecological pressures on biodiversity at local scales but also has

indirect effects in distant corners of the world. We suggest that the multibillion dollar cashmere industry

creates economic motivations that link western fashion preferences for cashmere to land use in Central

Asia. This penchant for stylish clothing, in turn, encourages herders to increase livestock production which

affects persistence of over 6 endangered large mammals in these remote, arid ecosystems. We hypothesized

that global trade in cashmere has strong negative effects on native large mammals of deserts and grassland

where cashmere-producing goats are raised. We used time series data, ecological snapshots of the biomass

of native and domestic ungulates, and ecologically and behaviorally based fieldwork to test our hypothesis.

In Mongolia increases in domestic goat production were associated with a 3-fold increase in local profits for

herders coexisting with endangered saiga (Saiga tatarica). That increasing domestic grazing pressure carries

fitness consequences was inferred on the basis of an approximately 4-fold difference in juvenile recruitment among blue sheep (Pseudois nayaur) in trans-Himalayan India. Across 7 study areas in Mongolia, India, and China’s Tibetan Plateau, native ungulate biomass is now <5% that of domestic species. Such trends suggest ecosystem degradation and decreased capacity for the persistence of native species, including at least 8 Asian endemic species: saiga, chiru (Pantholops hodgsoni), Bactrian camel (Camelus bactrianus), snow leopard (Panthera uncia), khulan (Equus hemionus), kiang (E. kiang), takhi (E. przewalski), and wild yak (Bos mutus). Our results suggest striking yet indirect and unintended actions that link trophic-level effects to markets induced by the trade for cashmere.

Title Snow Leopard Ecology and Conservation Issues in India Type Journal Article
Year 2017 Publication Resonance Abbreviated Journal
Volume Issue Pages (down) 677-690
Keywords
Abstract Snow leopard, an elusive mammal species of the cat family,

is the top-predator of the Central and South Asian, highaltitude

ecosystem. Snow leopards occur at low densities across

the Central Asian mountains and the Indian Himalayan region.

Owing to their secretive nature and inaccessible habitat,

little is known about its ecology and distribution. Due to

its endangered status and high aesthetic value, the snow leopard

is considered as an &#65533;umbrella species&#65533; for wildlife conservation

in the Indian Himalayas. This article summarizes the

current knowledge on snow leopard ecology and conservation

issues in the Indian context.

Title Predicting Habitat Suitability of Snow Leopards in the Western Himalayan Mountains, India Type Journal Article
Year 2020 Publication Biology bulletin Abbreviated Journal
Volume 47 Issue 6 Pages (down) 655-664
Keywords biogeographic distribution, climate, endangered cat, MaxEnt, snow leopard
Abstract The population of snow leopard (Panthera uncia) is declining

across their range, due to poaching, habitat fragmentation, retaliatory

killing, and a decrease of wild prey species. Obtaining information on

rare and cryptic predators living in remote and rugged terrain is

important for making conservation and management strategies. We used the

Maximum Entropy (MaxEnt) ecological niche modeling framework to predict

the potential habitat of snow leopards across the western Himalayan

region, India. The model was developed using 34 spatial species

occurrence points in the western Himalaya, and 26 parameters including,

prey species distribution, temperature, precipitation, land use and land

cover (LULC), slope, aspect, terrain ruggedness and altitude. Thirteen

variables contributed 98.6% towards predicting the distribution of snow

leopards. The area under the curve (AUC) score was high (0.994) for the

training data from our model, which indicates pre- dictive ability of

the model. The model predicted that there was 42432 km2 of potential

habitat for snow leop- ards in the western Himalaya region. Protected

status was available for 11247 km2 (26.5%), but the other 31185 km2

(73.5%) of potential habitat did not have any protected status. Thus,

our approach is useful for predicting the distribution and suitable

habitats and can focus field surveys in selected areas to save

resources, increase survey success, and improve conservation efforts for

snow leopards.
