Title | Population density of snow leopards (Panthera Uncia) in the Yage Valley Region of the Sanjiangyuan National Park: Conservation Implications and future directions | Type | Journal Article | ||
Year | 2020 | Publication | Artic, Antartic and Alpine Research | Abbreviated Journal | |
Volume | 52 | Issue | 1 | Pages | 541-550 |
Keywords | Snow leopard; population density; camera trapping; Tibetan Plateau; alpine ecosystem | ||||
Abstract | Population-based studies on snow leopard (Panthera uncia) are of theoretical and practical sig- nificance for the conservation of alpine ecosystems, though geographic remoteness and isolation hinder surveys in many promising regions. The Sanjiangyuan National Park on the Tibetan Plateau is acknowledged as a main snow leopard habitat, but most of the region remains unexplored and unknown. We adopted a combined approach of route survey and camera trapping survey to explore the population density of snow leopard in the Yage Valley region of the Sanjiangyuan National Park. Results indicated that (1) large populations of blue sheep contributed to the major food supply for snow leopards, along with diverse prey species as dietary supplementations, and (2) a population density of four to six snow leopards per 100 km2 on the north bank was estimated, and nine to fourteen individuals within the valley core areas were identified. We also argue that under the potential impacts of hydropower dams, this valley ecosystem should be symbolized as a conservation hotspot and therefore merits prioritized conservation. We recommend further surveys combined with novel methods/techniques and advocate a sustainable ecotourism model for the first V-shaped valley along the Yangtze mainstream. | ||||

Title | Meta-replication, sampling bias, and multi-scale model selection: A case study on snow leopard (Panthera uncia) in western China. | Type | Journal Article | ||
Year | 2020 | Publication | Ecology and Evolution | Abbreviated Journal | |

Abstract | Replicated multiple scale species distribution models (SDMs) have become increasingly important to identify the correct variables determining species distribution and their influences on ecological responses. This study explores multi-scale habitat relationships of the snow leopard (Panthera uncia) in two study areas on the Qinghai–Tibetan Plateau of western China. Our primary objectives were to evaluate the degree to which snow leopard habitat relationships, expressed by predictors, scales of response, and magnitude of effects, were consistent across study areas or locally landcape-specific. We coupled univariate scale optimization and the maximum entropy algorithm to produce multivariate SDMs, inferring the relative suitability for the species by ensembling top performing models. We optimized the SDMs based on average omission rate across the top models and ensembles’ overlap with a simulated reference model. Comparison of SDMs in the two study areas highlighted landscape-specific responses to limiting factors. These were dependent on the effects of the hydrological network, anthropogenic features, topographic complexity, and the heterogeneity of the landcover patch mosaic. Overall, even accounting for specific local differences, we found general landscape attributes associated with snow leopard ecological requirements, consisting of a positive association with uplands and ridges, aggregated low-contrast landscapes, and large extents of grassy and herbaceous vegetation. As a means to evaluate the performance of two bias correction methods, we explored their effects on three datasets showing a range of bias intensities. The performance of corrections depends on the bias intensity; however, density kernels offered a reliable correction strategy under all circumstances. This study reveals the multi-scale response of snow leopards to environmental attributes and confirms the role of meta-replicated study designs for the identification of spatially varying limiting factors. Furthermore, this study makes important contributions to the ongoing discussion about the best approaches for sampling bias correction. |

Title | Snow Leopard Smuggler Detained in Northwest China | Type | Miscellaneous | ||
Year | 2000 | Publication | Abbreviated Journal | ||
Volume | Issue | Pages | |||
Keywords | poaching; smuggling; China; snow-leopard; snow leopard; browse; 1020 | ||||
Abstract | Police have detained a man for trying to smuggle two snow leopards through the Xining Railway Station in northwest China's Qinghai Province. Ma Deliang was stopped by police after he attempted to pass the butchered snow leopards off as “beef” at a shop in Sichuan in southwest China. Suspicious of the contents in Ma's big sack, police asked experts from the local forestry bureau to check the meat and they found it to be flesh of two snow leopards, an endangered species on top state protection. Ma later confessed that he bought the dead snow leopards at a local market and wanted to smuggle them to Deyang, a city in southwest China's Sichuan province. Police also searched Ma's home and found dear heads, antlers and lynx and fox furs. Snow leopards live in highlands of altitudes between 3,000 to 6, 000 m above sea level. The population of the species has dwindled greatly since the 19th century. | ||||
