An analysis of the siberian tiger in eastern russia and asia

It has an extended supple body standing on rather short legs with a fairly long tail. The data used include weights of tigers that were older than 35 months and measured in the presence of authors. Their comparison with historical data indicates that up to the first half of the 20th century both male and female Siberian tigers were on average heavier than post ones.

They share physical and behavioural qualities of both parent species. Its pelage is dense and heavy, and colouration varies between shades of orange and brown with white ventral areas and distinctive vertical black stripes that are unique in each individual.

This is not due to skin pigmentation, but to the stubble and hair follicles embedded in the skin, similar to human beards colloquially five o'clock shadowand is in common with other big cats.

The pupils are circular with yellow irises. The small, rounded ears have a prominent white spot on the back, surrounded by black. The lion skull shows broader nasal openings.

Due to the variation in skull sizes of the two species, the structure of the lower jaw is a reliable indicator for their identifcation. The size difference between males and females is proportionally greater in the large tiger subspecies, with males weighing up to 1.

Males also have wider forepaw pads than females, enabling gender to be told from tracks. At the shoulder, tigers may variously stand 0. It allegedly weighed It is not albinism Colour variations A well-known allele found only in the Bengal population produces the white tigera colour variant first recorded in the Mughal Empire in the late 16th and early 17th centuries.

Genetically, whiteness is recessive: This has given white tigers a greater likelihood of being born with physical defects, such as cleft palatescoliosis curvature of the spineand strabismus squint.

In this colour morph, the stripes are extremely faint on the body while the tail has pale reddish-brown rings. Golden tigersanother colour morph, have pale golden pelage with a blond tone and reddish-brown stripes.

These types are rarely recorded in the wild. Today, its ecological habitats include the Siberian taiga as well as open grasslands and tropical mangrove swamps, and it has been classified as endangered in the IUCN Red List. Major reasons for the population decline include habitat destructionhabitat fragmentation and poaching.

The global wild population is estimated to number between 3, and 3, individuals, down from aroundat the start of the 20th century, with most remaining populations occurring in small pockets isolated from each other and with 2, of the total population living on the Indian subcontinent.

They were extirpated on the island of Bali in the s, around the Caspian Sea in the s, and on Java in the s. This was the result of habitat loss and the ongoing killing of tigers and tiger prey. The northern limit of their range is close to the Amur River in southeastern Siberia.

The only large island they still inhabit is Sumatra.Siberian tigers are understood to mainly inhabit eastern Russia, northeast China and northern parts of the Korean Peninsula. An estimated 18 to 22 live in northeast China's Heilongjiang and Jilin.

While Siberia falls entirely within Asia, many authorities such as the UN geoscheme will not subdivide countries and will place all of Russia as part of Europe and/or Eastern Europe.

Currently, they inhabit the far eastern edge of Asia, primarily in the birch forests that make up the region. The Amur (Siberian) tiger population, which was recently almost on the brink of extinction, is now happily roaring back.

The preliminary results of a recent census, launched with the support of the Russian government and which received the personal attention of President Putin, reveal that there are between and big cats roaming throughout their .
