“…In winter, most domestic animals were brought back to the villages near people, however their damage effect on vegetation was still there which reduced the ungulate prey population. Even so, the preferred food of Amur tigers is still wild boar and the majority of a tigers' diet consists of medium to large ungulates, mirroring the results of previous studies on tiger diet (Karanth & Sunquist 1995;Biswas & Sankar 2002;Miquelle et al 2007Miquelle et al , 2010Kapfer et al 2011). Therefore, with the lower ungulate density (especially wild boar), in order to survive, Amur tigers on the Chinese side did not avoid eating sika deer as strongly as on the Russian side.…”

A small, isolated Amur tiger population ranges across the southwest Primorskii Krai region in Russia and Hunchun region in China. Many individuals, with "dual nationality," cross the border frequently. Formulating effective conservation strategies requires a clear understanding of tiger food requirements in both countries. While the diets of tigers ranging in Russia is clearly understood, little is known of the tigers' feeding habits in China.. We used scat analysis combined with data on the abundance of 4 prey species to examine Amur tiger diet and prey preferences in Hunchun. We examined 53 tiger scat samples from 2011 to 2016 and found that tigers preyed on 12 species (11 species in winter), 4 of which were domestic animals with 33.58% biomass contribution; this was the first record of Amur tigers eating lynx in this area. Tigers showed a strong preference for wild boar (Jacobs index: +0.849), which were also the most frequently consumed prey, and a strong avoidance of roe deer (Jacobs index: -0.693). On the Russian side, domestic animals (just dog) were rarely found in tiger scat, and tigers did not show strong avoidance of roe deer, but of sika deer. We also found red deer footprints during winter surveys and that tigers ate red deer on the Chinese side, while there was no record of red deer feeding on the Russian side. Reducing or eliminating human disturbance, such as grazing, is essential to recovering tiger prey and habitat in this area and the Sino-Russian joint ungulate annual survey is indispensable for prey estimates of this small, isolated Amur tiger population.

“…The current range of Amur tigers (Panthera tigris altaica Timminck, 1884) includes the Sikhote-Alin Mountain Range from the cites of Vladivostok and Ussuriisk (southern Primorskii Krai) to the Amur River of Khabarovskii Krai in the north (Matyushkin et al 1996). There were an estimated 428-502 tigers in this region in 2005 (Miquelle et al 2007). Henry et al (2009) suggest that a small group of 10-20 animals in southwest Primorye and in the adjacent province of Jilin in China (Miquelle & Pikunov 2003;Sugimoto et al 2012) are genetically differentiable from the larger Sikhote-Alin population.…”

We used molecular genetic analyses to noninvasively identify individual Amur tigers and define subpopulations of tigers in the Russian Far East. We identified 63 individuals after genotyping 256 feces, 7 hair and 11 blood samples collected within southern, central and northern Sikhote-Alin, as well as Southwest Primorye. Analysis of nuclear DNA at 9 microsatellite loci demonstrated greater genetic similarity between animals from southern and northern Sikhote-Alin (some 500 km apart) than between animals from Ussuriskii State Nature Reserve and Southwest Primorye (less than 10 km apart at their nearest point), suggesting that a true barrier exists preventing movements of tigers between Southwest Primorye and the southern Sikhote-Alin Mountains.

“…The Siberian tiger or Amur tiger is a species of ''Panthera tigris'' whose habitat is Northeast China, North Korea, and the Russian Far East [60]. Various names have been given for the Siberian tiger, including ''Amur tiger,'' ''Ussurian tiger,'' ''Korean tiger,'' and ''Manchurian tiger,'' based on the different areas where they live [61].…”

Siberian Tiger Optimization: A New Bio-Inspired Metaheuristic Algorithm for Solving Engineering Optimization Problems

In this article, a new metaheuristic algorithm called Siberian Tiger Optimization (STO) is designed to deal with optimization applications. The fundamental inspiration of STO is the imitation of the natural behavior of the Siberian tiger during hunting and fighting. First, the whole design of STO and its mathematical model's two phases are explained. Then, the efficiency of the proposed STO approach in optimization tasks is evaluated on sets of various standard benchmark functions from the CEC 2017 test suite. In addition, the CEC 2011 test suite and four engineering design problems are employed to analyze the ability of STO to handle real-world applications. Finally, the quality of the optimization results obtained from the proposed STO approach is compared with the performance of twelve well-known metaheuristic algorithms. The simulation results show that STO, with its high power in exploration and exploitation and creating a balance between them, has provided better results than competitor algorithms and has superior performance in handling optimization applications.
