The Siberian tiger (Panthera tigris altaica), also called Amur tiger is a tiger subspecies inhabiting mainly the Sikhote Alin mountain region with a small population in southwest Primorye Province in the Russian Far East. The Siberian tiger once ranged throughout all of Korea, north-eastern China, Russian Far East, and eastern Mongolia. In 2005, there were 331–393 adult and subadult Siberian tigers in this region, with a breeding adult population of about 250 individuals. The population had been stable for more than a decade due to intensive conservation efforts, but partial surveys conducted after 2005 indicate that the Russian tiger population was declining. By 2015, the Siberian tiger population had increased to 480–540 individuals in the Russian Far East, including 100 cubs. A more detailed census revealed a total population of 562 wild Siberian tigers in Russia. This tiger subspecies was also called Korean tiger, Manchurian tiger, and Ussurian tiger, depending on the region where individuals were observed. The Siberian tiger and Bengal tiger subspecies rank among the biggest living cats. An average adult male Siberian outweighs an average adult male lion by around 45.5 kg (100 lb).[9] A comparison of data on body weights of Siberian tigers indicates that up to the first half of the 20th century both males and females were on average heavier than post-1970 ones. Todays wild Siberian tigers are smaller than Bengal tigers. Their reduced weight as compared to historical Siberian tigers may be due to a combination of causes: when captured, they were usually sick or injured and involved in a conflict situation with people. colonized Central Asia from eastern China via the Gansu−Silk Road corridor from eastern China, and then subsequently traversed Siberia eastward to establish the Amur tiger population in the Russian Far East The Siberian tiger is reddish-rusty, or rusty-yellow in color, with narrow black transverse stripes. The body length is not less than 150 cm (60 in), condylobasal length of skull 250 mm (10 in), zygomatic width 180 mm (7 in), and length of upper carnassial tooth over 26 mm (1 in) long. It has an extended supple body standing on rather short legs with a fairly long tail.[2] It is typically 5–10 cm (2–4 in) taller than the Bengal tiger, which is about 107–110 cm (42–43 in) tall. Body size The largest male, with largely assured references, measured 350 cm (140 in) "over the curves", equivalent to 330 cm (130 in) "between the pegs". The tail length in fully grown males is about 1 m (39 in). Weights of up to 318 kg (701 lb) have been recorded and exceptionally large males weighing up to 384 kg (847 lb) are mentioned, but no such cases are confirmed.[12] Mazák indicates the typical weight range of Siberian tigers as 180–306 kg (397–675 lb) for males and 100–167 kg (220–368 lb) for females. Exceptionally large individuals were targeted and shot by hunters. An unconfirmed report tells of a male tiger shot in the Sikhote-Alin Mountains in 1950 weighing 384 kg (847 lb) with an estimated length of 3.48 m (11.4 ft). In some cases, captive Siberian tigers reached a body weight of up to 465 kg (1,025 lb), such as the tiger "Jaipur. Measurements taken by scientists of the Siberian Tiger Project in Sikhote-Alin range from 200–450 cm (79–177 in) in head and body length measured in straight line, with an average of 195 cm (77 in) for males; and for females ranging from 167 to 182 cm (66 to 72 in) with an average of 174 cm (69 in). The average tail measures 99 cm (39 in) in males and 91 cm (36 in) in females. The longest male measured 309 cm (122 in) in total length (tail of 101 cm (40 in)) and had a chest girth of 127 cm (50 in). The longest female measured 270 cm (110 in) in total length (tail of 88 cm (35 in)) and had a chest girth of 108 cm (43 in). These measurements show that the present Amur tiger is generally longer than the Bengal tiger and the African lion. In 2005, a group of Russian, American and Indian zoologists published an analysis of historical and contemporary data on body weights of wild and captive tigers, both female and male across all subspecies. The data used include weights of tigers that were older than 35 months of age and measured in the presence of authors. The results of this analysis indicates that the average historical wild male Siberian tiger weighed 215.3 kg (475 lb) and the female 137.5 kg (303 lb); the contemporary wild male Siberian tiger weighs 176.4 kg (389 lb) on average with an asymptotic limit being 222.3 kg (490 lb); a wild female weighs 117.9 kg (260 lb) on average. Historical Siberian tigers and Bengal tigers were the largest ones, whereas contemporary Siberian tigers are lighter than Bengal tigers, on average. The reduction of the body weight of todays Siberian tigers may be explained by concurrent causes, namely the reduced abundance of prey due to illegal hunting and that the individuals were usually sick or injured and captured in a conflict situation with people.[10] A male captured by members of the Siberian Tiger Project weighed 206 kg (454 lb), and the largest male radiocollared weighed 212 kg (467 lb).
