Sumatran tiger (Panthera tigris sumatrae) found in Sumatra (Indonesia). Wild populations have about 400 to 500 children, is located mainly in five national parks on the island. The genetic testing has recently discovered the existence of the single gene markers, indicating that it may evolve into separate species, if it is not being made extinct. This led to the hypothesis that Sumatran tigers have greater importance in the preservation than any other race. Destruction of habitat is the main threat to the survival of this population (hunting even take place in national parks under protection), 66 children have been shootings in the years since 1998 to 2000-almost 20% of total tiger.
Siberian tiger (Panthera tigris altaica), also known as the Amur tiger, or tiger Manchuria (China called tiger Northeast东北虎), almost the entire assault in the very limited areas of eastern Russia, where today they are protected. In nature there are fewer than 400 children (now increased to 540 children), and of this population about the future is difficult to survive genetically, because of the potentially catastrophic inbreeding. Tigers Siberian tigers are the largest in size with males average length of 2.7 meters and weighing 290 kg, with thick fur and the big yellow road striping.
Tiger Malaysia (Panthera tigris jacksoni, synonymous : Panthera tigris malayensis), Malay: Harimau Malaya), is only found in the southern region of Peninsular Malaysia. Until 2004 it has not been recognized as a subspecies of tiger in the true sense that it deserves to be recognized. Sorting only occurs after study by Luo SJ et al. from the Laboratory of Gene Diversity, part of the National Cancer Institute of the United States. [15] Currently, it is estimated there are 600-800 Malayan tigers in the wild, making it the pants the third largest tiger, Bengal tiger and the tiger just after Indochina. However, it remains endangered subspecies. In terms of size, weight and power, it's almost like the Indochinese tiger.
Indochinese tiger (Panthera tigris corbetti), is found in Cambodia, China, Laos, Malaysia, Myanmar, Thailand and Vietnam. Their population is estimated to 1200-1800, probably in the low level of this range. The biggest populations in Malaysia, where poaching was tightly controlled, but all of this population is at high risk due to habitat fragmentation and inbreeding. In Vietnam, nearly 3/4 of tigers were killed to supply the Chinese medicine.
Tiger Bengal (Panthera tigris tigris) is found in the jungle and grasslands of Bangladesh, India, Bhutan, China and Nepal. [16] It is the national animal of both Bangladesh and India. Wild population estimates we are below 2,000, [17] the majority live in India and Bangladesh. Tiger of this race have come under pressure from shrinking habitat to poaching; some kind of specific drugs of traditional Chinese medicine (particularly in treating impotence) needs of tiger parts. Project Tiger, a conservation project of India began in 1972, achieved significant success in protecting this race.
Bali Tiger (Panthera tigris balica) had on the island of Bali. Where they were hunted to extinction; Bali last tiger was killed in Sumbar for Kima, West Bali on September 27, 1937; it is an adult female tiger. No one yet Bali tigers living in captivity. Tiger still plays an important role in Hindu religion in Bali.
Java Tiger (Panthera tigris sondaica) already exist on the Indonesian island of Java. This race is probably extinct since the early 1980s, as a result of hunting and habitat destruction, but their extinction could take place from 1950 onwards (while one that has less than 25 children in the wild). The last tiger was seen in 1979. The
Caspian tiger or Persian tiger (Panthera tigris virgata) have become extinct since the late 1960s, with the last being seen in 1968. In the past, we distributed Afghanistan, Iran, Iraq, Pakistan, the former Soviet Union and Turkey.
There are no fossils of tigers to be found, except the fossil found in Southeast Asia, most of the Pleistocene. However, there are 100,000 years old fossilized parts of tiger found in Alaska. Perhaps through the seam between Siberia and Alaska during the last ice age, this tiger of the North American population of tigers tiger Siberian. In addition, the researchers also found a relationship between tigers and lions bone Americas: an extinct species of cats have dominated North America about 10,000 years ago. The findings contradict this leads to a hypothesis that the American lion originated a new continent tigers. The fossils of tigers were unearthed in Japan shows Japanese tiger is not bigger than the tigers of the island of the same period. This phenomenon is probably due to the correlation between body size and open space as well as the prey density is not much.
