We used data from camera traps set for capturing snow leopards（Panthera uncia） in the Yanchiwan National Nature Reserve,Gansu Province,China,to assess species richness with respect to mammal and birds species. We also assessed survey efficiency for species detection,and conducted an initial analysis of species interactions. The survey effort of 10,171 camera workdays yielded 2,868 suitable animal image events involving 17 mammal and 20 bird species. Among these,the dhole（Cuon alpinus） is considered to be Endangered,the snow leopard and white-lipped deer（Cervus albirostris） Vulnerable,and the Pallas＇ s cat（Feli smanul）,mountain weasel（Mustela altaica）,Himalayan griffon（Gyps himalayensis） and cinereous vulture（Aegypius monachus） Near Threatened under the IUCN red list. Fourteen species were also listed as key protected wild animals according to China national standards. Both the rarefaction curves and richness estimators suggested our sampling for mammal and pheasant species is sufficient,while more survey efforts are still needed to detect other bird species. With a focus on the dominant species Eurasian lynx（Lynx lynx）,occupancy models were used to estimate site use and detection probability for selected species,and to investigate predator-prey relationships between lynx on the one hand and woolly hare（Lepus oiostolus）,pika（Ochotona spp.）and Tibetan partridge（Perdix hodgsoniae） on the other. We give recommendations on how to increase efficiency in camera-based species inventory and biodiversity monitoring.展开更多

In many parts of China,large human populations and increasing development has led to an escalation in HWC with both carnivore and prey species. In this paper we assess herder attitudes toward blue sheep（Pseudaois nayaur,Hodgson,1833）,white lipped deer（Carvus albirostris,Przewalski,1883）,red deer（Cervus elaphus,Linnaeus,1758）,and marmot（Marmota himalayana Hodgson,1841） through interview-based surveys conducted in 46 households across 8 villages in Qilianshan National Nature Reserve,Gansu,China. We also examine the perceived impact of three ecological-restoration policies（anti-grazing,sustainable grazing,and grass-planting policies） on livelihoods,and how this affects attitudes toward wildlife. Herders reported neutral attitudes toward wildlife species in general,but reported negative attitudes towards blue sheep. Mixed-effects modeling revealed that herder attitudes toward the target species varied significantly across villages,but other socioeconomic variables had limited explanatory power for attitudes. Furthermore,we found that while policy implementation was negatively perceived by herders,anti-grazing policy implementation and total policy implementation were positively correlated with positive attitudes toward wildlife,highlighting a potential gap between perceived threats and actual threats. Finally,we show that the leading cause of reported livestock death is preventable disease,alleviation of which may help improve attitudes toward wildlife.展开更多
