Christiansen, P. (2007). Canine morphology in the larger Felidae: implications for feeding ecology. Biological Journal of the Linnean Society, 91, 573–592.
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.

Han, X. M., D. G., Zhang, E., Jones, M., and Jin, T.. (2001). Far eastern leopard and Siberian tiger conservation measures. (pp. 102–103). Harbin: Widlife Conservation Society.
Abstract: Workshop to develop a recovery plan for the wild north China tiger population. October 20th to 23th, 2000, Harbin.
Like the Siberian Tiger, the Far Eastern Leopard is one of China's largest Felidae and lives mainly in the eastern mountains of Jilin Province. The number of leopards is very low and it is even more endangered than the tiger. There is a very close relationship between leopard and tiger conservation, especially in areas where overlap occurs. In these areas, special emphasis has to be placed on each of the species' specific conservation needs. There is urgent need to step up our efforts to study and monitor leopard populations and to develop a conservation strategy. This document contains information of the status and main threats of the Far Eastern leopard and makes recommendations on needed conservation measures.

Hongfa, X. and K., C. (2006). The State of Wildlife Trade in China. Information on the trade in wild animals and plants in China 2006..
Abstract: Welcome to the first edition of The State of Wildlife Trade in China. This publication takes a broad look at wildlife trade over the past year, particularly concerning the impact of China's consumption on globally important biodiversity 'hotspots'. The focus of The State of Wildlife Trade in China is on emerging trends in China's wildlife trade and up-to-date reviews of work to stop illegal wildlife trade and support sustainable trade. The lead story in this issue is the illegal trade in Tigers and other Asian big cats. During 2006, surveys continued to document this illegal trade, as well as highlight opportunities for action. Other stories in this issue give updates on trade in reef fishes from Southeast Asia's 'Coral Triangle' and in timber from the forests of the Russian Far East, Borneo, and East Africa. China's wildlife trade presents both challenges and opportunities. This annual report aims to provide current information about wildlife trade in China and to provide avenues for involvement in China's conservation community. It is part of TRAFFIC's on-going commitment to turn information into action.

Riordan, P. (1998). Unsupervised recognition of individual tigers and snow leopards from their footprints (Vol. 1).
Abstract: This study presents the testing of two unsupervised classification methods for their ability to accurately identify unknown individual tigers, Panthera tigris, and snow leopards, Panthera uncia, from their footprints. A neural-network based method, the Kohonen self-organizing map (SOM), and a Bayesian method, AutoClass, were assessed using hind footprints taken from captive animals under standardized conditions. AutoClass successfully discriminated individuals of both species from their footprints. Classification accuracy was greatest for tigers, with more misclassification of individuals occurring for snow leopards. Examination of variable influence on class formations failed to identify consistently influential measurements for either species. The self-organizing map did not provide accurate classification of individuals for either species. Results were not substantially improved by altering map dimensions nor by using principal components derived from the original data. The interpretation of resulting classifications and the importance of using such techniques in the study of wild animal populations are discussed. The need for further testing in the field is highlighted.
