Siberian Tiger - Panthera tigris altacia
The Siberian tiger (Panthera tigris altaica), also known as the Amur tiger, is a tiger subspecies inhabiting mainly the Sikhote Alin mountain region with a small subpopulation in southwest Primorye province in the Russian Far East. In 2005, there were 331–393 adult-subadult Amur tigers in this region, with a breeding adult population of about 250 individuals. The population has been stable for more than a decade due to intensive conservation efforts, but partial surveys conducted after 2005 indicate that the Russian tiger population is declining. The Siberian tiger is the largest living felid and ranks among the biggest felids to ever exist. Results of a phylogeographic study comparing mitochondrial DNA from Caspian tigers and living tiger subspecies indicate that the common ancestor of the Amur and Caspian subspecies 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. It is typically 5–10 cm (2–4 in) taller than the Bengal tiger, which is about 107–110 cm (42–43 in) tall. Measurements taken by scientists of the Siberian Tiger Project in Sikhote-Alin range from 178 to 208 cm (70 to 82 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 "Maurice" 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 "Maria Ivanna" 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 longer than the Bengal tiger and the African lion. According to modern research of wild Siberian tigers in Sikhote-Alin, an average adult male of more than 35 months of age weighs 176.4 kg (389 lb), the average asymptotic limit being 222.3 kg (490 lb); an adult tigress weighs 117.9 kg (260 lb). The mean weight of historical Siberian tigers is supposed to be higher: 215.3 kg (475 lb) for male tigers and 137.5 kg (303 lb) for females. In May 2011, a male called "Banzai" weighing 207 kg (456 lb) was radio-collared. This individual is heavier but smaller in size than a previously radio-collared male.
European Bison - Bison bonasus
The European bison (Bison bonasus), also known as wisent ( /ˈviːzənt/ or /ˈwiːzənt/) or the European wood bison, is a Eurasian species of bison. It is the heaviest surviving wild land animal in Europe; a typical European bison is about 2.1 to 3.1 m (7 to 10 ft) long, not counting a tail of 30 to 60 cm (12 to 24 in) long, and 1.6 to 2 m (5 to 7 ft) tall. Weight typically can range from 300 to 920 kg (660 to 2,000 lb), with an occasional big bull to 1,000 kg (2,200 lb) or more. On average, it is slightly lighter in body mass and yet is taller at the shoulder than the American Bison (Bison bison). Compared to the American species, the European bison has shorter hair on the neck, head and forequarters, but longer tail and horns. European bison were hunted to extinction in the wild, with the last wild animals being shot in the Białowieża Forest in Eastern Poland in 1919 and in the Western Caucasus in 1927, but have since been reintroduced from captivity into several countries in Europe, all descendants of the Białowieża or lowland European bison. Although superficially similar, there are a number of physical and behavioral differences between the European bison and the American bison. The European bison has 14 pairs of ribs, while the American Bison has 15. Adult European bison are taller than American bison, and have longer legs. European bison tend to browse more, and graze less than their American cousins, due to their necks being set differently. Compared to the American bison, the nose of the European bison is set further forward than the forehead when the neck is in a neutral position. The European bison is a herd animal, which lives in both mixed and solely-male groups. Mixed groups consist of infants, young aged 2–3 years, calves and young adult bulls. European bison feed predominantly on grasses although they will also browse on shoots and leaves.
