Morphology

provided by Animal Diversity Web

Tigers have a reddish-orange coat with vertical black stripes along the flanks and shoulders that vary in size, length, and spacing. Some subspecies have paler fur and some are almost fully white with either black or dark brown stripes along the flanks and shoulders. The underside of the limbs and belly, chest, throat, and muzzle are white or light. White is found above the eyes and extends to the cheeks. A white spot is present on the back of each ear. The dark lines about the eyes tend to be symmetrical, but the marks on each side of the face are often asymmetrical. The tail is reddish-orange and ringed with several dark bands.

Body size and morphology varies considerably among subspecies of tigers. Siberian tigers, also know as Amur tigers (P. t. altaica), are the largest. Male Siberian tigers can grow to 3.7 meters and weigh over 423 kg; females are up to 2.4 meters in length and 168 kg. Male Indochinese tigers (P. t. corbetti), though smaller than Siberian tigers in body size at 2.85 meters in length and 195 kg, have the longest skull of all tiger subspecies, measuring 319 to 365 mm. Sumatran tigers (P. t. sumatrae) are the smallest living subspecies. Male Sumatran tigers measure 2.34 meters and weigh 136 kg; females measure 1.98 meters and weigh 91 kg.

Tigers are powerful animals, one is known to have dragged a gaur bull weighing 700 kg. Tigers have short, thick necks, broad shoulders, and massive forelimbs, ideal for grappling with prey while holding on with long retractible claws and broad forepaws. A tiger’s tongue is covered with hard papillae, to scrape flesh off the bones of prey.

All tigers have a dental formula of 3/3, 1/1, 3/2, 1/1. Bengal tigers (P. t. tigris) have the longest canines of any living large cat; from 7.5 to 10 cm in length. A tiger's skull is robust, short, and broad with wide zygomatic arches. The nasal bones are high, projecting little further than the maxillary, where the canines fit. Tigers have a well-developed sagittal crest and coronoid processes, providing muscle attachment for their strong bite.

Range mass: 91 to 423 kg.

Range length: 1.98 to 3.7 m.

Other Physical Features: endothermic ; homoiothermic; bilateral symmetry

Sexual Dimorphism: male larger

Average basal metabolic rate: 133.859 W.

Life Expectancy

provided by Animal Diversity Web

Tigers usually live 8 to 10 years in the wild, although they can reach ages into their 20's. In captivity tigers have been known to live up to 26 years old, although a typical captive lifespan is 16 to 18 years. It is estimated that most adult tigers die as a result of human persecution and hunting, although their large prey can occasionally wound them fatally. Young tigers face numerous dangers when they disperse from their mother's home range, including being attacked and eaten by male tigers. Some researchers estimate a 50% survival rate for young tigers.

Habitat

provided by Animal Diversity Web

Tigers live in a wide variety of habitats, suggested by their distribution across a wide range of ecological conditions. They are known to occur in tropical lowland evergreen forest, monsoonal forest, dry thorn forest, scrub oak and birch woodlands, tall grass jungles, and mangrove swamps. Tigers are able to cope with a broad range of climatic variation, from warm moist areas, to areas of extreme snowfall where temperatures may be as low as –40 degrees Celsius. Tigers have been found at elevations of 3,960 meters. In general, tigers require only some vegetative cover, a source of water, and sufficient prey.

Distribution

provided by Animal Diversity Web

The range of tigers once extended across Asia from eastern Turkey and the Caspian Sea south of the Tibetan plateau eastward to Manchuria and the Sea of Okhotsk. Tigers were also found in northern Iran, Afghanistan, the Indus valley of Pakistan, Laos, Thailand, Vietnam, Cambodia, Malaysia, and the islands of Java and Bali. Tigers are now extinct or nearly extinct in most of these areas. Populations remain relatively stable in northeastern China, Korea, Russia, and parts of India and the Himalayan region.

There are eight recognized subspecies of Panthera tigris. Siberian tigers, P. t. altaica, are currently found only in a small part of Russia, including the Amurussuri region of Primorye and Khabarovsk. Bengal tigers, P. t. tigris, are found in India, Bangladesh, Nepal, Bhutan, and China. Indochinese tigers, P. t. corbetti, are found in Cambodia, China, Laos, Malaysia, Myanmar, Thailand, and Vietnam. South China tigers, P. t. amoyensis, are found in three isolated areas in southcentral China. Sumatran tigers, P. t. sumatrae, are found only on the Indonesian island of Sumatra. Bali tigers (P. t. balica), Javan tigers (P. t. sondaica), and Caspian tigers (P. t. virgata) are thought to be extinct. Those subspecies occurred on the islands of Bali (P. t. balica), Java (P. t. sondaica), and in Turkey, the Transcaucasus region, Iran, and central Asia (P. t. virgata).

Trophic Strategy

provided by Animal Diversity Web

Tigers prefer to hunt at night, when their ungulate prey are most active. In a study done in India by Schaller (1967), tigers were most active before 0800 and after 1600 hours. Tigers are thought to locate their prey using hearing and sight more than olfaction (Schaller, 1967). They use a stealthy approach, taking advantage of every rock, tree and bush as cover and rarely chase prey far. Tigers are silent, taking cautious steps and keeping low to the ground so they are not sighted or heard by the prey. They typically kill by ambushing prey, throwing the prey off balance with their mass as they leap onto it. Tigers are successful predators but only 1 out of 10 to 20 attacks result in a successful hunt.

Tigers use one of two tactics when they get close enough to kill. Small animals, weighing less than half the body weight of the tiger, are killed by a bite to the back of the neck. The canines are inserted between the neck vertebrae forcing them apart and breaking the spinal cord. For larger animals, a bite to the throat is used to crush the animal’s trachea and suffocate it. The throat bite is the safer killing tactic because it minimizes any physical assault the tiger may receive while trying to kill its prey. After the prey is taken to cover, tigers feed first on the buttocks using the carnassials to rip open the carcass. As the tiger progresses it opens the body cavity and removes the stomach. Not all of the prey is eaten; some parts are rejected. Prey are usually dragged to cover and may be left there and revisited over several days.

The majority of the tiger diet consists of various large ungulate species, including sambar (Rusa unicolor), chital (Axis axis), hog deer (Axis porcinus), barasingha (Rucervus duvaucelii), barking deer (Muntiacus muntjak), elk (Cervus elaphus), sika deer (Cervus nippon), Eurasian elk (Alces alces), roe deer (Capreolus capreolus), muskdeer (Moschus moschiferus), nilgai (Boselaphus tragocamelus), black buck (Antilope cervicapra), gaur (Bos frontalis), banteng (Bos javanicus), water buffalo (Bubalus bubalis), and wild pigs (Sus). Domestic ungulates are also taken, including cattle (Bos taurus), water buffalo (Bubalus bubalis), horses (Equus caballus), and goats (Capra hircus). In rare cases tigers attack Malayan tapirs (Tapirus indicus), Indian elephants (Elephas maximus), and young Indian rhinoceroses (Rhinoceros unicornis). Tigers regularly attack and eat brown bears (Ursus arctos), Asiatic black bears (Ursus thibetanus), and sloth bears (Melursus ursinus). Smaller animals are sometimes taken when larger prey is unavailable, this includes large birds such as pheasants (Phasianinae), leopards (Panthera pardus), fish, crocodiles (Crocodylus), turtles, porcupines (Hystrix), rats, and frogs. A very few tigers begin to hunt humans (Homo sapiens). Tigers will eat between 18 and 40 kg of meat when they successfully take large prey, they do not typically eat every day.

Tigers help regulate populations of their large herbivore prey, which put pressure on plant communities. Because of their role as top predators, they may be considered keystone species.

Tiger parasites include the nematode, trematode, and cestode worms: Paragonimus westermani, Toxocara species, Uiteinarta species, Physaloptera praeputhostoma, Dirofilaria species, Gnathostoma spinigerum, Diphyllobothrium erinacei, Taenia bubesei, and Taenia pisiformis. Ticks known from tigers are Rhipicephalus annulatus, Dermacentor marginatus, Hyalomma truncatum, Hyalomma kumari, Hyalomma marginata, and Rhipicelphalus turanicus.

Benefits

provided by Animal Diversity Web

Live tigers are of economic importance in zoos where they are displayed to the public and in wildlife areas where they may bring in tourism. Tigers are illegally killed for their fur to make rugs and wall hangings. In addition, for more than 3000 years traditional Chinese medicine has used tiger parts to treat sickness and injury. The humerus (upper leg bone), for example, has been prescribed to treat rheumatism even though there is no evidence that it has any affect on the disease. Some believe that tiger bones will help them become as strong and ferocious as the tiger.

Benefits

provided by Animal Diversity Web

Normally tigers avoid human contact, very rarely tigers may become “man eaters”. A man-eating tigress was rumored to have killed over 430 people, including 234 over the course of four years. It is thought that man-eating tigers are those that cannot effectively prey on large ungulated because they have become crippled, are old, or no longer have suitable native habitat and prey available. Because human populations are rapidly increasing, competition over natural resources is increasing pressure on tigers and their habitat and increasing the likelihood of negative human-tiger interactions.

Negative Impacts: injures humans (bites or stings)

Panthera tigris has 38 chromosomes. The karyotype has 16 pairs of metacentric and submetacentric autosomes and two pairs of acrocentric autosomes. The X chromosome is a medium-sized metacentric and the Y chromosomes is a small metacentric.

Maltese tigers (sometimes referred to as P. t. melitensis, although they are not a true subspecies) are a variety of tiger that results from inbreeding. Maltese tigers have white fur with grey hues, making them look blue from a distance. So called 'white tigers' result when a cub is born with two recessive forms of a gene, also the result of inbreeding. White tigers suffer from many problems including eye weakness, sway backs, and twisted necks.

Behavior

provided by Animal Diversity Web

Communication among tigers is maintained by scent markings, visual signals, and vocalization. Scent markings are deposited in the form of an odorous musky liquid that is mixed with urine and sprayed on objects like grass, trees, or rocks. A facial expression called “flehmen” is often associated with scent detection. During flehmen, the tongue hangs over the incisors, the nose is wrinkled, and the upper canines are bared. Flehmen is commonly seen in males that have just sniffed urine, scent marks, an estrous tigress, or a cub of their own species.

Visual signals made by tigers include spots that have been sprayed, scrapes made by raking the ground, and claw marks left on trees or other objects. Schaller (1967) described a “defense threat” facial expression observed when a tiger is attacking. This involved pulling the corners of the open mouth back, exposing the canines, fattening the ears, and enlarging the pupils of the eyes. The spots on the back of their ears and their pattern of stripes may also be used in intraspecific communication.

Tigers can also communicate vocally with roars, growls, snarls, grunts, moans, mews, and hisses. Each sound has its own purpose, and appears to reflect the tiger's intent or mood. For example, a tiger’s roar is usually a signal of dominance; it tells other individuals how big it is and its location. A moan communicates submission. The ability of tigers to roar comes from having a flexible hyoid apparatus and vocal fold with a thick fibro- elastic pad that allows sound to travel long distances.

Reproduction

provided by Animal Diversity Web

Tigers are solitary and do not associate with mates except for mating. Local males may compete for access to females in estrus.

Mating System: polygynandrous (promiscuous)

Female tigers come into estrus every 3 to 9 weeks and are receptive for 3 to 6 days. They have a gestation period of about 103 days (from 96 to 111 days), after which they give birth to from 1 to 7 altricial cubs. Average litter sizes are 2 to 3 young. In Siberian tigers the average litter size is 2.65 (n=123), similar averages have been found in other tiger subspecies. Newborn cubs are blind and helpless, weighing from 780 to 1600 g. The eyes do not open until 6 to 14 days after birth and the ears from 9 to 11 days after birth. The mother spends most of her time nursing the young during this vulnerable stage. Weaning occurs at 90 to 100 days old. Cubs start following their mother at about 2 months old and begin to take some solid food at that time. From 5 to 6 months old the cubs begin to take part in hunting expeditions. Cubs stay with their mother until they are 18 months to 3 years old. Young tigers do not reach sexual maturity until around 3 to 4 years of age for females and 4 to 5 years of age for males.

Breeding interval: Female tigers give birth every 3 to 4 years, depending on the length of dependence of previous cubs.

Breeding season: Tigers can breed at any time of the year, but breeding is most common from November to April.

Range number of offspring: 1 to 7.

Average number of offspring: 2.65.

Range gestation period: 96 to 111 days.

Average gestation period: 103 days.

Average weaning age: 90 to 100 days.

Average time to independence: 18 months.

Average age at sexual or reproductive maturity (female): 3 to 4 years.

Average age at sexual or reproductive maturity (male): 4 to 5 years.

Key Reproductive Features: iteroparous ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; induced ovulation ; viviparous

Average birth mass: 1190 g.

Average number of offspring: 2.5.

Average age at sexual or reproductive maturity (male)
Sex: male:
1415 days.

Average age at sexual or reproductive maturity (female)
Sex: female:
1268 days.

Like other mammals, females care for and nurse their dependent young. Weaning occurs at 3 to 6 months, but cubs are dependent on their mother until they become proficient hunters themselves, when they reach 18 months to 3 years old. Young tigers must learn to stalk, attack, and kill prey from their mother. A mother caring for cubs must increase her killing rate by 50% in order to get enough nutrition to satisfy herself and her offspring. Male tigers do not provide parental care.

Parental Investment: altricial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female); pre-independence (Provisioning: Female, Protecting: Female); extended period of juvenile learning

Biology

provided by Arkive
Tigers are predominately solitary creatures, they occupy territories that are defended against intruders of the same sex and are marked with urine and scrapes at the boundaries (2). Males have larger territories that overlap those of several females, with whom they mate (2). Mating occurs throughout the year and the female gives birth to a litter of around two to three cubs after a four month gestation period (3). Cubs learn to hunt and kill from around six months of age but remain dependent on their mother for at least 15 months, after which time they will disperse to find their own territory (2). Tigers are 'stalk and ambush' predators and their stripy coat provides effective camouflage in tall grass and forest (2). Hunting mainly occurs at night and the principal prey consists of deer and wild pigs, although tigers prey on a variety of other animals and will also eat carrion (3). Unlike other species of cats, tigers are competent swimmers; they will readily enter the water, and can be found lying half-submerged in streams and lakes in the mid-day heat (3).

Conservation

provided by Arkive
The tiger is classified as Endangered by the IUCN (the World Conservation Union), and of the six surviving subspecies the futures of the South China tiger and the Siberian tiger seem particularly bleak. Recent extensive surveys resulted in no sightings (10). India has the greatest number of tigers but even the Bengal tiger population is estimated at no more than 3,000 to 3,500 individuals (3). TRAFFIC (the trade monitoring arm of the WWF and IUCN) monitors the level of international trade of tiger products and brings it to the attention of the relevant authorities (6). The Indian government established Project Tiger in 1973 (7) with the aim of conserving the tiger population. Within India there are currently 21 tiger reserves, although, these are increasingly threatened by human pressures on the land (3). The key to the survival of the tiger is the maintenance of large tracts of contiguous habitat, but protection of this species is complicated by its man-eater reputation and by the threat posed to livestock (2). The involvement and commitment of local people will be vital for the future sustainability of this most regal of cats.

Description

provided by Arkive
One of the largest of the 'big cats', the tiger is an instantly recognisable and emotive animal. Nine different subspecies are recognised, three of which became extinct in the latter part of the 20th Century; the Bali (P. t. balica), Javan (P. t. sondaica) and Caspian tigers (P. t. virgata). The remaining subspecies are the Siberian (P. t. altaica), South China (P. t. amoyensis), Sumatran (P. t. sumatrae), Indochinese (P. t. corbetti), Malayan (P. t. jacksoni)and Bengal tigers (P. t. tigris) (3) (10). The different subspecies vary in their body size, coat colour and markings, with the Sumatran tiger being the smallest and darkest, whilst the Siberian tiger is the largest and palest subspecies (4). Markings and coat colour can overlap between subspecies and are not often used to differentiate (10). Generally however, tigers have a reddish-orange to yellow-ochre coat with a white belly and black markings, the pattern of which is unique (2). Like the other big cats, tigers are well adapted for hunting large prey and have short, heavily-muscled forelimbs and long, sharp, retractable claws (2). Extreme colour varieties are occasionally seen in the wild, such as whitish-grey tigers with chocolate stripes which are the result of two tigers with a recessive gene breeding (2). However, whilst this colour variation is popular with zoos, it is not of conservation significance (2).

Threats

provided by Arkive
Human activities are the principal cause of declining tiger numbers. Hunting was a major cause of mortality in the past; both for trophies and as part of organised pest control measures (3). Poaching and illegal killing, for example by livestock owners, today remains one of the major threats to the survival of the species, particularly with the growing demand for tiger bones in Oriental 'medicine' (5). The demand for remedies made from tiger parts has increased due to increasing affluence in Asia, and laws preventing international trade in tiger parts are largely ignored. Hong Kong is the main importer of tiger products, with tiger bone the most used part. The bones are crushed to be used in anti-inflammatory drugs for rheumatism and arthritis, amongst many other uses. The trade in tiger skins is also increasing (11). Habitat loss has occurred through much of the tiger's range and also threatens survival; as land becomes rapidly developed to meet the increasing demand of the Asian population explosion (3), tiger populations become isolated in remaining fragments of wilderness and ultimately die out (2). The tiger's natural prey species have declined in numbers due to over-hunting, leading individuals to turn to domestic livestock, which inevitably causes conflict with local farmers (3).

Description of Panthera tigris

provided by BioPedia
The tiger (Panthera tigris) is the largest cat species, reaching a total body length of up to 3.3 metres (11 ft) and weighing up to 306 kg (670 lb). Their most recognizable feature is a pattern of dark vertical stripes on reddish-orange fur with lighter underparts. They have exceptionally stout teeth, and their canines are the longest among living felids with a crown height of as much as 74.5 mm (2.93 in) or even 90 mm (3.5 in). Tigers once ranged widely across Asia, from Turkey in the west to the eastern coast of Russia. Over the past 100 years, they have lost 93% of their historic range, and have been extirpated from southwest and central Asia, from the islands of Java and Bali, and from large areas of Southeast and Eastern Asia. Today, they range from the Siberian taiga to open grasslands and tropical mangrove swamps. The remaining six tiger subspecies have been classified as endangered by IUCN. The global population in the wild is estimated to number between 3,062 to 3,948 individuals, with most remaining populations occurring in small pockets that are isolated from each other. Major reasons for population decline include habitat destruction, habitat fragmentation and poaching.[1] The extent of area occupied by tigers is estimated at less than 1,184,911 km2 (457,497 sq mi), a 41% decline from the area estimated in the mid-1990s. Tigers are territorial and generally solitary but social animals, often requiring large contiguous areas of habitat that support their prey requirements. This, coupled with the fact that they are indigenous to some of the more densely populated places on earth, has caused significant conflicts with humans. In zoos, tigers have lived for 20 to 26 years, which also seems to be their longevity in the wild. Tigers have featured prominently in ancient mythology and folklore, and continue to be depicted in modern films and literature. Tigers appear on many flags, coats of arms, and as mascots for sporting teams. The Bengal tiger is the national animal of Bangladesh and India.

Tiger

provided by wikipedia EN

The tiger (Panthera tigris) is the largest living cat species and a member of the genus Panthera. It is most recognisable for its dark vertical stripes on orange fur with a white underside. An apex predator, it primarily preys on ungulates, such as deer and wild boar. It is territorial and generally a solitary but social predator, requiring large contiguous areas of habitat to support its requirements for prey and rearing of its offspring. Tiger cubs stay with their mother for about two years and then become independent, leaving their mother's home range to establish their own.

The tiger was first scientifically described in 1758. It once ranged widely from the Eastern Anatolia Region in the west to the Amur River basin in the east, and in the south from the foothills of the Himalayas to Bali in the Sunda Islands. Since the early 20th century, tiger populations have lost at least 93% of their historic range and have been extirpated from Western and Central Asia, the islands of Java and Bali, and in large areas of Southeast and South Asia and China. What remains of the range where tigers still roam free is fragmented, stretching in spots from Siberian temperate forests to subtropical and tropical forests on the Indian subcontinent, Indochina and a single Indonesian island, Sumatra.

The tiger is listed as Endangered on the IUCN Red List. As of 2015, the global wild tiger population was estimated to number between 3,062 and 3,948 mature individuals, with most populations living in small isolated pockets. India currently hosts the largest tiger population. Major reasons for population decline are habitat destruction, habitat fragmentation and poaching. Tigers are also victims of human–wildlife conflict, due to encroachment in countries with a high human population density.

The tiger is among the most recognisable and popular of the world's charismatic megafauna. It featured prominently in the ancient mythology and folklore of cultures throughout its historic range and continues to be depicted in modern films and literature, appearing on many flags, coats of arms and as mascots for sporting teams. The tiger is the national animal of India, Bangladesh, Malaysia and South Korea.

Etymology

The Middle English tigre and Old English tigras derive from Old French tigre, from Latin tigris. This was a borrowing of Classical Greek τίγρις 'tigris', a foreign borrowing of unknown origin meaning 'tiger' and the river Tigris.[5] The origin may have been the Persian word tigra ('pointed or sharp') and the Avestan word tigrhi ('arrow'), perhaps referring to the speed of the tiger's leap, although these words are not known to have any meanings associated with tigers.[6]

The generic name Panthera is derived from the Latin word panthera and the Ancient Greek word πάνθηρ ('panther').[7]

Taxonomy

In 1758, Carl Linnaeus described the tiger in his work Systema Naturae and gave it the scientific name Felis tigris.[2] In 1929, the British taxonomist Reginald Innes Pocock subordinated the species under the genus Panthera using the scientific name Panthera tigris.[8][9]

Subspecies

Phylogenetic relationship of tiger populations based on Driscoll et al. (2009).[10]

Following Linnaeus's first descriptions of the species, several tiger specimens were described and proposed as subspecies.[11] The validity of several tiger subspecies was questioned in 1999. Most putative subspecies described in the 19th and 20th centuries were distinguished on basis of fur length and colouration, striping patterns and body size, hence characteristics that vary widely within populations. Morphologically, tigers from different regions vary little, and gene flow between populations in those regions is considered to have been possible during the Pleistocene. Therefore, it was proposed to recognize only two tiger subspecies as valid, namely P. t. tigris in mainland Asia, and P. t. sondaica in the Greater Sunda Islands.[12]

This two-subspecies proposal was reaffirmed in 2015 by a comprehensive analysis of morphological, ecological and molecular traits of all putative tiger subspecies using a combined approach. The authors proposed recognition of only two subspecies, namely P. t. tigris comprising the Bengal, Malayan, Indochinese, South Chinese, Siberian and Caspian tiger populations of continental Asia, and P. t. sondaica comprising the Javan, Bali and Sumatran tiger populations of the Sunda Islands. The continental nominate subspecies P. t. tigris constitutes two clades: a northern clade composed of the Siberian and Caspian tiger populations, and a southern clade composed of all other mainland populations.[13]

The authors of the 2015 study noted that this two-subspecies reclassification will affect tiger conservation management.[13] It would make captive breeding programs and future re-wilding of zoo-born tigers easier, as one tiger population could then be used to bolster the population of another population. However, there is the risk that the loss of subspecies uniqueness could negatively impact protection efforts for specific populations.[14]

In 2017, the Cat Classification Task Force of the IUCN Cat Specialist Group revised felid taxonomy in accordance with the two-subspecies proposal of the comprehensive 2015 study, and recognized the tiger populations in continental Asia as P. t. tigris, and those in the Sunda Islands as P. t. sondaica.[15]

This two-subspecies view is still disputed by researchers, since the currently recognized nine subspecies can be distinguished genetically.[14] Results of a 2018 whole-genome sequencing of 32 specimens support six monophyletic tiger clades corresponding with the living subspecies and indicate that the most recent common ancestor lived about 110,000 years ago.[16]

The following tables are based on the classification of the species Panthera tigris provided in Mammal Species of the World,[11] and also reflect the classification used by the Cat Classification Task Force in 2017:[15]

Evolution

Restoration of a Panthera zdanskyi skull, an extinct tiger relative whose fossil remains were found in northwest China

The tiger's closest living relatives were previously thought to be the Panthera species lion, leopard and jaguar. Results of genetic analysis indicate that about 2.88 million years ago, the tiger and the snow leopard lineages diverged from the other Panthera species, and that both may be more closely related to each other than to the lion, leopard and jaguar.[31][32] The geographic origin of the Panthera is most likely northern Central Asia. The tiger–snow leopard lineage dispersed in Southeast Asia during the Miocene.[33]

Panthera zdanskyi is considered to be a sister taxon of the modern tiger. It lived at the beginning of the Pleistocene about two million years ago, its fossil remains were excavated in Gansu of northwestern China. It was smaller and more "primitive", but functionally and ecologically similar to the modern tiger. It is disputed as to whether it had the striping pattern. Northwestern China is thought to be the origin of the tiger lineage. Tigers grew in size, possibly in response to adaptive radiations of prey species like deer and bovids, which may have occurred in Southeast Asia during the Early Pleistocene.[34]

Panthera tigris trinilensis lived about 1.2 million years ago and is known from fossils excavated near Trinil in Java.[35] The Wanhsien, Ngandong, Trinil, and Japanese tigers became extinct in prehistoric times.[36] Tigers reached India and northern Asia in the late Pleistocene, reaching eastern Beringia, Japan, and Sakhalin. Some fossil skulls are morphologically distinct from lion skulls, which could indicate tiger presence in Alaska during the last glacial period, about 100,000 years ago.[37]

Fossil teeth and bones found in Borneo were attributed to the Bornean tiger and date to about 13,745 to 3,000 years ago. It may have accessed Borneo, when the sea level was low during a glaciation period, and may have survived until about 200 years ago.[38][39] In the Ille Cave on the island of Palawan, two articulated phalanx bones were found amidst an assemblage of other animal bones and stone tools. They were smaller than mainland tiger fossils, possibly due to insular dwarfism.[40] It has been speculated that the tiger parts were either imported from elsewhere, or that the tiger colonised Palawan from Borneo before the Holocene.[41][42] Fossil remains of tigers were also excavated in Sri Lanka, China, Japan and Sarawak dating to the Late Pliocene, Pleistocene and Early Holocene.[37][38]

Results of a phylogeographic study indicate that all living tigers had a common ancestor 108,000 to 72,000 years ago.[24] The potential tiger range during the late Pleistocene and Holocene was predicted applying ecological niche modelling based on more than 500 tiger locality records combined with bioclimatic data. The resulting model shows a contiguous tiger range at the Last Glacial Maximum, indicating gene flow between tiger populations in mainland Asia. The Caspian tiger population was likely connected to the Bengal tiger population through corridors below elevations of 4,000 m (13,000 ft) in the Hindu Kush. The tiger populations on the Sunda Islands and mainland Asia were possibly separated during interglacial periods.[43]

The tiger's full genome sequence was published in 2013. It was found to have repeat compositions much as other cat genomes and "an appreciably conserved synteny".[44]

Hybrids

Captive tigers were bred with lions to create hybrids called liger and tigon. They share physical and behavioural qualities of both parent species. Breeding hybrids is now discouraged due to the emphasis on conservation.[45] The liger is a cross between a male lion and a tigress. Ligers are typically between 3 and 3.5 m (10 and 12 ft) in length, and weigh between 350 and 450 kg (800 and 1,000 lb) or more.[46] Because the lion sire passes on a growth-promoting gene, but the corresponding growth-inhibiting gene from the female tiger is absent, ligers grow far larger than either parent species.[47]

The less common tigon is a cross between a lioness and a male tiger.[45] Because the male tiger does not pass on a growth-promoting gene and the lioness passes on a growth inhibiting gene, tigons are around the same size as their parents.[47] Some females are fertile and have occasionally given birth to litigons when mated to a male Asiatic lion.[48]

Description

The tiger has a muscular body with strong forelimbs, a large head and a tail that is about half the length of its body. Its pelage colouration varies between shades of orange with a white underside and distinctive vertical black stripes; the patterns of which are unique in each individual.[49][22] Stripes are likely advantageous for camouflage in vegetation such as long grass with strong vertical patterns of light and shade.[50][51] The tiger is one of only a few striped cat species; it is not known why spotted patterns and rosettes are the more common camouflage pattern among felids.[52] The orange colour may also aid in camouflage as the tiger's prey are dichromats, and thus may perceive the cat as green and blended in with the vegetation.[53]

A tiger's coat pattern is still visible when it is shaved. This is not due to skin pigmentation, but to the stubble and hair follicles embedded in the skin.[54] It has a mane-like heavy growth of fur around the neck and jaws and long whiskers, especially in males. The pupils are circular with yellow irises. The small, rounded ears have a prominent white spot on the back, surrounded by black.[22] These spots are thought to play an important role in intraspecific communication.[55]

The tiger's skull is similar to a lion's skull, with the frontal region usually less depressed or flattened, and a slightly longer postorbital region. 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 identification.[18] The tiger has fairly stout teeth; its somewhat curved canines are the longest among living felids with a crown height of up to 90 mm (3.5 in).[22]

Size

There is notable sexual dimorphism between male and female tigers, with the latter being consistently smaller. The size difference between them is proportionally greater in the large tiger subspecies, with males weighing up to 1.7 times more than females. Males also have wider forepaw pads, enabling sex to be identified from tracks.[56] It has been hypothesised that body size of different tiger populations may be correlated with climate and be explained by thermoregulation and Bergmann's rule, or by distribution and size of available prey species.[22][57]

Generally, males vary in total length from 220 to 310 cm (87 to 122 in) and weigh between 90 and 258 kg (198 and 569 lb) with skull length ranging from 295 to 383 mm (11.6 to 15.1 in). Females vary in total length from 190 to 275 cm (75 to 108 in), weigh 65 to 167 kg (143 to 368 lb) with skull length ranging from 265 to 318 mm (10.4 to 12.5 in).[58] In either sex, the tail represents about 0.6 to 1.1 m (2 ft 0 in to 3 ft 7 in) of the total length. The Bengal and Siberian tigers are amongst the tallest cats in shoulder height. They are also ranked among the biggest cats that have ever existed reaching weights of more than 300 kg (660 lb).[22] The tigers of the Sunda islands are smaller and less heavy than tigers in mainland Asia, rarely exceeding 142 kg (313 lb) in weight.[25]

Colour variations

There are three other colour variants – white, golden and nearly stripeless snow white – that are now virtually non-existent in the wild due to the reduction of wild tiger populations, but continue in captive populations. The white tiger has white fur and sepia-brown stripes. The golden tiger has a pale golden pelage with a blond tone and reddish-brown stripes. The snow white tiger is a morph with extremely faint stripes and a pale reddish-brown ringed tail. Both snow white and golden tigers are homozygous for CORIN gene mutations.[59]

The white tiger lacks pheomelanin (which creates the orange colour), and has dark sepia-brown stripes and blue eyes. This altered pigmentation is caused by a mutant gene that is inherited as an autosomal recessive trait, which is determined by a white locus. It is not an albino, as the dark pigments are scarcely affected.[60][59] The mutation changes a single amino acid in the transporter protein SLC45A2. Both parents need to have the allele for whiteness to have white cubs.[61] Between the early and mid 20th century, white tigers were recorded and shot in the Indian states of Odisha, Bihar, Assam and in the area of Rewa, Madhya Pradesh. The local maharaja started breeding tigers in the early 1950s and kept a white male tiger together with its normal-coloured daughter; they had white cubs.[62] To preserve this recessive trait, only a few white individuals were used in captive breeding, which led to a high degree of inbreeding. Inbreeding depression is the main reason for many health problems of captive white tigers, including strabismus, stillbirth, deformities and premature death.[63] Other physical defects include cleft palate and scoliosis.[64]

The Tiger Species Survival Plan has condemned the breeding of white tigers, alleging they are of mixed ancestry and of unknown lineage. The genes responsible for white colouration are represented by 0.001% of the population. The disproportionate growth in numbers of white tigers points to inbreeding among homozygous recessive individuals. This would lead to inbreeding depression and loss of genetic variability.[65]

There are also records of pseudo-melanic or black tigers which have thick stripes that merge. In Simlipal National Park, 37% of the tiger population has this condition, which has been linked to isolation and inbreeding.[66]

Distribution and habitat

Historical distribution of the tiger[10]

The tiger historically ranged from eastern Turkey and Transcaucasia to the coast of the Sea of Japan, and from South Asia across Southeast Asia to the Indonesian islands of Sumatra, Java and Bali.[49] Since the end of the last glacial period, it was probably restricted by periods of deep snow lasting longer than six months.[67][68] Currently, it occurs in less than 6% of its historical range, as it has been extirpated from Southwest and Central Asia, large parts of Southeast and East Asia. It now mainly occurs in the Indian subcontinent, the Indochinese Peninsula, Sumatra and the Russian Far East, while its status in the Korean Peninsula is unknown.[50][1][69]

The tiger is essentially associated with forest habitats.[38][70] Tiger populations thrive where populations of wild cervids, bovids and suids are stable.[71] Records in Central Asia indicate that it occurred foremost in Tugay riverine forests along the Atrek, Amu Darya, Syr Darya, Hari, Chu and Ili Rivers and their tributaries. In the Caucasus, it inhabited hilly and lowland forests.[18] Historical records in Iran are known only from the southern coast of the Caspian Sea and adjacent Alborz Mountains.[72] In the Amur-Ussuri region, it inhabits Korean pine and temperate broadleaf and mixed forests, where riparian forests provide food and water, and serve as dispersal corridors for both tiger and ungulates.[68][73] On the Indian subcontinent, it inhabits mainly tropical and subtropical moist broadleaf forests, moist evergreen forests, tropical dry forests and the swamp forests of the Sundarbans.[74] In the Eastern Himalayas, tigers were documented in temperate forest up to an elevation of 4,200 m (13,800 ft) in Bhutan and of 3,630 m (11,910 ft) in the Mishmi Hills.[75][76] In Thailand, it lives in deciduous and evergreen forests.[77] In Sumatra, tiger populations range from lowland peat swamp forests to rugged montane forests.[78]

Ecology and behaviour

Social and daily activities

When not subject to human disturbance, the tiger is mainly diurnal.[79] It does not often climb trees but cases have been recorded.[50] It is a strong swimmer and often bathes in ponds, lakes and rivers, thus keeping cool in the heat of the day.[80] Individuals can cross rivers up to 7 km (4.3 mi) wide and can swim up to 29 km (18 mi) in a day.[81] During the 1980s, a tiger was observed frequently hunting prey through deep lake water in Ranthambhore National Park.[79]

The tiger is a long-ranging species, and individuals disperse over distances of up to 650 km (400 mi) to reach tiger populations in other areas.[82] Radio-collared tigers in Chitwan National Park started dispersing from their natal areas earliest at the age of 19 months. Four females dispersed between 0 and 43.2 km (0.0 and 26.8 mi), and 10 males between 9.5 and 65.7 km (5.9 and 40.8 mi). None of them crossed open cultivated areas that were more than 10 km (6.2 mi) wide, but moved through forested habitat.[83]

Adult tigers lead largely solitary lives. They establish and maintain territories but have much wider home ranges within which they roam. Resident adults of either sex generally confine their movements to their home ranges, within which they satisfy their needs and those of their growing cubs. Individuals sharing the same area are aware of each other's movements and activities.[84] The size of the home range mainly depends on prey abundance, geographic area and sex of the individual.[50][22] In India, home ranges appear to be 50 to 1,000 km2 (19 to 386 sq mi) while in Manchuria, they range from 500 to 4,000 km2 (190 to 1,540 sq mi). In Nepal, defended territories are recorded to be 19 to 151 km2 (7.3 to 58.3 sq mi) for males and 10 to 51 km2 (3.9 to 19.7 sq mi) for females.[81]

Young female tigers establish their first territories close to their mother's. The overlap between the female and her mother's territory reduces with time. Males, however, migrate further than their female counterparts and set out at a younger age to mark out their own area. A young male acquires territory either by seeking out an area devoid of other male tigers, or by living as a transient in another male's territory until he is older and strong enough to challenge the resident male. Young males seeking to establish themselves thereby comprise the highest mortality rate (30–35% per year) amongst adult tigers.[85]

Females playing in Ranthambore Tiger Reserve

To identify his territory, the male marks trees by spraying urine,[86][87] anal gland secretions, marking trails with feces and marking trees or the ground with their claws. Females also use these "scrapes", urine and fecal markings. Scent markings of this type allow an individual to pick up information on another's identity, sex and reproductive status. Females in oestrus will signal their availability by scent marking more frequently and increasing their vocalisations.[50]

Although for the most part avoiding each other, tigers are not always territorial and relationships between individuals can be complex. An adult of either sex will sometimes share its kill with others, even with unrelated tigers. George Schaller observed a male share a kill with two females and four cubs. Unlike male lions, male tigers allow females and cubs to feed on the kill before the male is finished with it; all involved generally seem to behave amicably, in contrast to the competitive behaviour shown by a lion pride.[88] Stephen Mills described a social feeding event in Ranthambore National Park:

A dominant tigress they called Padmini killed a 250 kg (550 lb) male nilgai – a very large antelope. They found her at the kill just after dawn with her three 14-month-old cubs, and they watched uninterrupted for the next ten hours. During this period the family was joined by two adult females and one adult male, all offspring from Padmini's previous litters, and by two unrelated tigers, one female the other unidentified. By three o'clock there were no fewer than nine tigers round the kill.[85]

Male tigers are generally less tolerant of other males within their territories than females are of other females. Territory disputes are usually solved by intimidation rather than outright violence. Several such incidents have been observed in which the subordinate tiger yielded by rolling onto its back and showing its belly in a submissive posture.[89] Once dominance has been established, a male may tolerate a subordinate within his range, as long as they do not live in too close quarters.[85] The most serious disputes tend to occur between two males competing for a female in oestrus, sometimes fighting to the death.[85][89]

Facial expressions include the "defense threat", where an individual bares its teeth, flattens its ears and its pupils enlarge. Both males and females show a flehmen response, a characteristic grimace, when sniffing urine markings, but flehmen is more often associated with males detecting the markings made by tigresses in oestrus.[22]

Tigers roar to signal their presence to other individuals over long distances. This vocalization is forced through an open mouth as it closes and can be heard 3 km (1.9 mi) away. They may roar three or four times in a row, and other tigers may respond in kind. When tense, tigers will moan, a sound similar to a roar but softer and made when the mouth is at least partially closed. Moaning can be heard 400 m (1,300 ft) away.[22][88] Aggressive encounters involve growling, snarling and hissing.[88] During an attack, an explosive "coughing roar" or "coughing snarl" is emitted through an open mouth and exposed teeth.[22][88][90] Chuffing—soft, low-frequency snorting similar to purring in smaller cats—is heard in more friendly situations.[91] Other vocalizations include grunts, woofs and miaows.[22]

Hunting and diet

Tigers mostly feed on large and medium-sized mammals, particularly ungulates weighing 60–250 kg (130–550 lb). Range-wide, the most selected prey are sambar deer, Manchurian wapiti, barasingha and wild boar. Tigers are capable of taking down larger prey like adult gaur and wild water buffalo,[92] but opportunistically eat much smaller prey, such as monkeys, peafowl and other ground-based birds, hares, porcupines and fish.[50] They also prey on other predators, including dogs, leopards, bears, snakes and crocodiles.[93] Tiger attacks on adult Asian elephants and Indian rhinoceros have also been reported.[94][95][96] More often, tigers take the more vulnerable small calves.[97] When in close proximity to humans, tigers sometimes prey on domestic livestock like cattle, horses and donkeys. Although almost exclusively carnivorous, tigers occasionally eat vegetation for dietary fibre such as fruit of the slow match tree.[93]

The tigers is thought to be mainly a nocturnal predator.[70] It generally hunts alone and overpowers its prey from any angle, using its body size and strength to knock the prey off balance. Successful hunts usually require the tiger to almost simultaneously leap onto its quarry, knock it over, and grab the throat or nape with its teeth.[81] Some tigers can reach speeds of about 49–65 km/h (30–40 mph) but only in short bursts; consequently, tigers must be close to their prey before they break cover. If the prey senses the tiger's presence before this, the tiger usually abandons the hunt rather than give chase or battle pre-alerted prey. Horizontal leaps of up to 10 m (33 ft) have been reported, although leaps of around half this distance are more typical. One in 2 to 20 hunts, including stalking near potential prey, ends in a successful kill.[81][70]

When hunting larger animals, tigers prefer to bite the throat and use their powerful forelimbs to hold onto the prey, often simultaneously wrestling it to the ground. The tiger remains latched onto the neck until its target dies of strangulation.[88] By this method, tigers killed gaurs and water buffaloes weighing over a ton.[98] Although they can kill healthy adults, tigers often select the calves or infirm of very large species.[99] Healthy adult prey of this type can be dangerous to tackle, as long, strong horns, legs and tusks are all potentially fatal to the tiger. No other extant land predator routinely takes on prey this large on its own.[18][100]

With small prey such as monkeys and hares, the tiger bites the nape, often breaking the spinal cord, piercing the windpipe, or severing the jugular vein or common carotid artery.[101] Rarely, tigers have been observed to kill prey by swiping with their paws, which are powerful enough to smash the skulls of domestic cattle,[93] and break the backs of sloth bears.[102]

After killing their prey, tigers sometimes drag it to conceal it in vegetation, grasping with their mouths at the site of the killing bite. This, too, can require great physical strength. In one case, after it had killed an adult gaur, a tiger was observed to drag the massive carcass over a distance of 12 m (39 ft). When 13 men simultaneously tried to drag the same carcass later, they were unable to move it.[81] An adult tiger can go for up to two weeks without eating, then gorge on 34 kg (75 lb) of flesh at one time. In captivity, adult tigers are fed 3 to 6 kg (6.6 to 13.2 lb) of meat a day.[81]

Enemies and competitors

Tigers usually prefer to eat self-killed prey, but eat carrion in times of scarcity and also steal prey from other large carnivores. Although predators typically avoid one another, if a prize is under dispute or a serious competitor is encountered, displays of aggression are common. If these fail, the conflicts may turn violent; tigers may kill or even prey on competitors such as leopards, dholes, striped hyenas, wolves, bears, pythons, and mugger crocodiles on occasion.[27][102][103][104][105] Crocodiles, bears, and large packs of dholes may win conflicts with tigers, and crocodiles and bears can even kill them.[27][18][106][107]

The considerably smaller leopard avoids competition from tigers by hunting at different times of the day and hunting different prey.[108] In India's Nagarhole National Park, most prey selected by leopards were from 30 to 175 kg (66 to 386 lb) against a preference for heavier prey by tigers. The average prey weight in the two respective big cats in India was 37.6 kg (83 lb) against 91.5 kg (202 lb).[109][110] With relatively abundant prey, tigers and leopards were seen to successfully coexist without competitive exclusion or interspecies dominance hierarchies that may be more common to the African savanna, where the leopard lives beside the lion.[109] Golden jackals may scavenge on tiger kills.[111] Tigers appear to inhabit the deep parts of a forest while smaller predators like leopards and dholes are pushed closer to the fringes.[112]

Reproduction and life cycle

The tiger mates all year round, but most cubs are born between March and June, with a second peak in September. Gestation ranges from 93 to 114 days, with an average of 103 to 105 days. A female is only receptive for three to six days.[113] Mating is frequent and noisy during that time.[49] The female gives birth in a sheltered location such as in tall grass, in a dense thicket, cave or rocky crevice. The father generally takes no part in rearing.[18] Litters consist of two or three cubs, rarely as many as six. Cubs weigh from 780 to 1,600 g (28 to 56 oz) each at birth, and are born with eyes closed. They open their eyes when they are six to 14 days old.[113] Their milk teeth break through at the age of about two weeks. They start to eat meat at the age of eight weeks. At around this time, females usually shift them to a new den.[49] They make short ventures with their mother, although they do not travel with her as she roams her territory until they are older. Females lactate for five to six months.[113] Around the time they are weaned, they start to accompany their mother on territorial walks and are taught how to hunt.[79]

A dominant cub emerges in most litters, usually a male. The dominant cub is more active than its siblings and takes the lead in their play, eventually leaving its mother and becoming independent earlier.[79] The cubs start hunting on their own earliest at the age of 11 months, and become independent around 18 to 20 months of age.[88] They separate from their mother at the age of two to two and a half years, but continue to grow until the age of five years.[49] Young females reach sexual maturity at three to four years, whereas males at four to five years.[18] Unrelated wandering male tigers often kill cubs to make the female receptive, since the tigress may give birth to another litter within five months if the cubs of the previous litter are lost. The mortality rate of tiger cubs is about 50% in the first two years. Few other predators attack tiger cubs due to the diligence and ferocity of the mother. Apart from humans and other tigers, common causes of cub mortality are starvation, freezing, and accidents.[100] Generation length of the tiger is about eight years.[114] The oldest recorded captive tiger lived for 26 years.[81]

Occasionally, male tigers participate in raising cubs, usually their own, but this is extremely rare and not always well understood. In May 2015, Amur tigers were photographed by camera traps in the Sikhote-Alin Nature Reserve. The photos show a male Amur tiger pass by, followed by a female and three cubs within the span of about two minutes.[115] In Ranthambore, a male Bengal tiger raised and defended two orphaned female cubs after their mother had died of illness. The cubs remained under his care, he supplied them with food, protected them from his rival and sister, and apparently also trained them.[116]

Conservation

In the 1990s, a new approach to tiger conservation was developed: Tiger Conservation Units (TCUs), which are blocks of habitat that have the potential to host tiger populations in 15 habitat types within five bioregions. Altogether 143 TCUs were identified and prioritized based on size and integrity of habitat, poaching pressure and population status. They range in size from 33 to 155,829 km2 (13 to 60,166 sq mi).[74]

In 2016, an estimate of a global wild tiger population of approximately 3,890 individuals was presented during the Third Asia Ministerial Conference on Tiger Conservation.[118][125] The WWF subsequently declared that the world's count of wild tigers had risen for the first time in a century.[126]

Major threats to the tiger include habitat destruction, habitat fragmentation and poaching for fur and body parts, which have simultaneously greatly reduced tiger populations in the wild.[1] In India, only 11% of the historical tiger habitat remains due to habitat fragmentation.[127] Demand for tiger parts for use in traditional Chinese medicine has also been cited as a major threat to tiger populations.[128][129][130] Some estimates suggest that there are fewer than 2,500 mature breeding individuals, with no subpopulation containing more than 250 mature breeding individuals.[1]

India is home to the world's largest population of wild tigers.[118] A 2014 census estimated a population of 2,226, a 30% increase since 2011.[131] On International Tiger Day 2019, the 'Tiger Estimation Report 2018' was released by Prime Minister Narendra Modi. The report estimates a population of 2967 tigers in India with 25% increase since 2014. Modi said "India is one of the safest habitats for tigers as it has achieved the target of doubling the tiger population from 1411 in 2011 to 2967 in 2019".[132] As of 2022, India accounts for 75 percent of global tiger population.[133] The Tiger Census of 2023 reports tiger population in India at 3167.[134]

In 1973, India's Project Tiger, started by Indira Gandhi, established numerous tiger reserves. The project was credited with tripling the number of wild Bengal tigers from some 1,200 in 1973 to over 3,500 in the 1990s, but a 2007 census showed that numbers had dropped back to about 1,400 tigers because of poaching.[135][136][137] Following the report, the Indian government pledged $153 million to the initiative, set up measures to combat poaching, promised funds to relocate up to 200,000 villagers in order to reduce human-tiger interactions,[138] and set up eight new tiger reserves in India.[139] India also reintroduced tigers to the Sariska Tiger Reserve[140] and by 2009 it was claimed that poaching had been effectively countered at Ranthambore National Park.[141]

In the 1940s, the Siberian tiger was on the brink of extinction with only about 40 animals remaining in the wild in Russia. As a result, anti-poaching controls were put in place by the Soviet Union and a network of protected zones (zapovedniks) were instituted, leading to a rise in the population to several hundred. Poaching again became a problem in the 1990s, when the economy of Russia collapsed. The major obstacle in preserving the species is the enormous territory individual tigers require, up to 450 km (280 mi) needed by a single female and more for a single male.[142] Current conservation efforts are led by local governments and NGO's in concert with international organisations, such as the World Wide Fund for Nature and the Wildlife Conservation Society.[143] The competitive exclusion of wolves by tigers has been used by Russian conservationists to convince hunters to tolerate the big cats. Tigers have less impact on ungulate populations than do wolves, and are effective in controlling the latter's numbers.[144] In 2005, there were thought to be about 360 animals in Russia, though these exhibited little genetic diversity.[145] However, in a decade later, the Siberian tiger census was estimated from 480 to 540 individuals.[146]

In China, tigers became the target of large-scale 'anti-pest' campaigns in the early 1950s, where suitable habitats were fragmented following deforestation and resettlement of people to rural areas, who hunted tigers and prey species. Though tiger hunting was prohibited in 1977, the population continued to decline and is considered extinct in southern China since 2001.[147][148] Having earlier rejected the Western-led environmentalist movement, China changed its stance in the 1980s and became a party to the CITES treaty. By 1993 it had banned the trade in tiger parts, and this diminished the use of tiger bones in traditional Chinese medicine.[149] The Tibetan people's trade in tiger skins has also been a threat to tigers. The pelts were used in clothing, tiger-skin chuba being worn as fashion. In 2006 the 14th Dalai Lama was persuaded to take up the issue. Since then there has been a change of attitude, with some Tibetans publicly burning their chubas.[150]

In 1994, the Indonesian Sumatran Tiger Conservation Strategy addressed the potential crisis that tigers faced in Sumatra. The Sumatran Tiger Project (STP) was initiated in June 1995 in and around the Way Kambas National Park to ensure the long-term viability of wild Sumatran tigers and to accumulate data on tiger life-history characteristics vital for the management of wild populations.[151] By August 1999, the teams of the STP had evaluated 52 sites of potential tiger habitat in Lampung Province, of which only 15 these were intact enough to contain tigers.[152] In the framework of the STP a community-based conservation program was initiated to document the tiger-human dimension in the park to enable conservation authorities to resolve tiger-human conflicts based on a comprehensive database rather than anecdotes and opinions.[153]

The Wildlife Conservation Society and Panthera Corporation formed the collaboration Tigers Forever, with field sites including the world's largest tiger reserve, the 21,756 km2 (8,400 sq mi) Hukaung Valley in Myanmar. Other reserves were in the Western Ghats in India, Thailand, Laos, Cambodia, the Russian Far East covering in total about 260,000 km2 (100,000 sq mi).[154]

Tigers have been studied in the wild using a variety of techniques. Tiger population have been estimated using plaster casts of their pugmarks, although this method was criticized as being inaccurate.[155] More recent techniques include the use of camera traps and studies of DNA from tiger scat, while radio-collaring has been used to track tigers in the wild.[156] Tiger spray has been found to be just as good, or better, as a source of DNA than scat.[157]

Relationship with humans

Tiger hunting

Tiger hunting on elephant-back in India, 1808

The tiger has been one of the most sought after game animals of Asia. Tiger hunting took place on a large scale in the early 19th and 20th centuries, being a recognised and admired sport by the British in colonial India, the maharajas and aristocratic class of the erstwhile princely states of pre-independence India. A single maharaja or English hunter could claim to kill over a hundred tigers in their hunting career.[81] Over 80,000 tigers were slaughtered in just 50 years spanning from 1875 to 1925 in British-ruled India.[158] Tiger hunting was done by some hunters on foot; others sat up on machans with a goat or buffalo tied out as bait; yet others on elephant-back.[159] King George V on his visit to Colonial India in 1911 killed 39 tigers in a matter of 10 days[160] One of these is on display at the Royal Albert Memorial Museum.[161]

Historically, tigers have been hunted at a large scale so their famous striped skins could be collected. The trade in tiger skins peaked in the 1960s, just before international conservation efforts took effect. By 1977, a tiger skin in an English market was considered to be worth US$4,250.[81]

Body part use

Tiger parts are commonly used as amulets in South and Southeast Asia. In the Philippines, the fossils in Palawan were found besides stone tools. This, besides the evidence for cuts on the bones, and the use of fire, suggests that early humans had accumulated the bones,[40] and the condition of the tiger subfossils, dated to approximately 12,000 to 9,000 years ago, differed from other fossils in the assemblage, dated to the Upper Paleolithic. The tiger subfossils showed longitudinal fracture of the cortical bone due to weathering, which suggests that they had post-mortem been exposed to light and air. Tiger canines were found in Ambangan sites dating to the 10th to 12th centuries in Butuan, Mindanao.[41][42]

Many people in China and other parts of Asia have a belief that various tiger parts have medicinal properties, including as pain killers and aphrodisiacs.[162] There is no scientific evidence to support these beliefs. The use of tiger parts in pharmaceutical drugs in China is already banned, and the government has made some offences in connection with tiger poaching punishable by death. Furthermore, all trade in tiger parts is illegal under the Convention on International Trade in Endangered Species of Wild Fauna and Flora and a domestic trade ban has been in place in China since 1993.[163]

However, the trading of tiger parts in Asia has become a major black market industry and governmental and conservation attempts to stop it have been ineffective to date.[81] Almost all black marketers engaged in the trade are based in China and have either been shipped and sold within in their own country or into Taiwan, South Korea or Japan.[81] The Chinese subspecies was almost completely decimated by killing for commerce due to both the parts and skin trades in the 1950s through the 1970s.[81] Contributing to the illegal trade, there are a number of tiger farms in the country specialising in breeding them for profit. It is estimated that between 5,000 and 10,000 captive-bred, semi-tame animals live in these farms today.[164][165][166] However, many tigers for traditional medicine black market are wild ones shot or snared by poachers and may be caught anywhere in the tiger's remaining range (from Siberia to India to the Malay Peninsula to Sumatra). In the Asian black market, a tiger penis can be worth the equivalent of around $300 U.S. dollars. In the years of 1990 through 1992, 27 million products with tiger derivatives were found.[81] In July 2014 at an international convention on endangered species in Geneva, Switzerland, a Chinese representative admitted for the first time his government was aware trading in tiger skins was occurring in China.[167]

Man-eating tigers

Wild tigers that have had no prior contact with humans actively avoid interactions with them. However, tigers cause more human deaths through direct attack than any other wild mammal.[81] Attacks are occasionally provoked, as tigers lash out after being injured while they themselves are hunted. Attacks can be provoked accidentally, as when a human surprises a tiger or inadvertently comes between a mother and her young,[169] or as in a case in rural India when a postman startled a tiger, used to seeing him on foot, by riding a bicycle.[170] Occasionally tigers come to view people as prey. Such attacks are most common in areas where population growth, logging, and farming have put pressure on tiger habitats and reduced their wild prey. Most man-eating tigers are old, missing teeth, and unable to capture their preferred prey.[50] For example, the Champawat Tiger, a tigress found in Nepal and then India, had two broken canines. She was responsible for an estimated 430 human deaths, the most attacks known to be perpetrated by a single wild animal, by the time she was shot in 1907 by Jim Corbett.[171] According to Corbett, tiger attacks on humans are normally in daytime, when people are working outdoors and are not keeping watch.[172] Early writings tend to describe man-eating tigers as cowardly because of their ambush tactics.[173]

Man-eaters have been a particular problem in recent decades in India and Bangladesh, especially in Kumaon, Garhwal and the Sundarbans mangrove swamps of Bengal, where some healthy tigers have hunted humans. Because of rapid habitat loss attributed to climate change, tiger attacks have increased in the Sundarbans.[174] The Sundarbans area had 129 human deaths from tigers from 1969 to 1971. In the 10 years prior to that period, about 100 attacks per year in the Sundarbans, with a high of around 430 in some years of the 1960s.[81] Unusually, in some years in the Sundarbans, more humans are killed by tigers than vice versa.[81] In 1972, India's production of honey and beeswax dropped by 50% when at least 29 people who gathered these materials were devoured.[81] In 1986 in the Sundarbans, since tigers almost always attack from the rear, masks with human faces were worn on the back of the head, on the theory that tigers usually do not attack if seen by their prey. This decreased the number of attacks only temporarily. All other means to prevent attacks, such as providing more prey or using electrified human dummies, did not work as well.[175]

In captivity

In Ancient Roman times, tigers were kept in menageries and amphitheatres to be exhibited, trained and paraded, and were often provoked to fight gladiators and other exotic beasts.[176][177] Since the 17th century, tigers, being rare and ferocious, were sought after to keep at European castles as symbols of their owners' power. Tigers became central zoo and circus exhibits in the 18th century: a tiger could cost up to 4,000 francs in France (for comparison, a professor of the Beaux-Arts at Lyons earned only 3,000 francs a year),[178] or up to $3,500 in the United States, where a lion cost no more than $1,000.[179]

In 2007, over 4,000 captive tigers lived in China, of which 3,000 were held by about 20 larger facilities, with the rest held by some 200 smaller facilities.[180] In 2011, 468 facilities in the USA kept 2,884 tigers.[181] Nineteen US states banned private ownership of tigers, fifteen require a license, and sixteen states have no regulation.[182] Genetic ancestry of 105 captive tigers from fourteen countries and regions showed that forty-nine animals belonged distinctly to five subspecies; fifty-two animals had mixed subspecies origins.[183] Many Siberian tigers in zoos today are actually the result of crosses with Bengal tigers.[184]

Cultural depictions

Tigers and their superlative qualities have been a source of fascination for mankind since ancient times, and they are routinely visible as important cultural and media motifs. They are also considered one of the charismatic megafauna, and are used as the face of conservation campaigns worldwide. In a 2004 online poll conducted by cable television channel Animal Planet, involving more than 50,000 viewers from 73 countries, the tiger was voted the world's favourite animal with 21% of the vote, narrowly beating the dog.[185]

Mythology and legend

Tiger and Magpie, a Korean minhwa (folk art) painting, late 19th century.

In Chinese mythology and culture, the tiger is one of the 12 animals of the Chinese zodiac. In Chinese art, the tiger is depicted as an earth symbol and equal rival of the Chinese dragon – the two representing matter and spirit respectively. The Southern Chinese martial art Hung Ga is based on the movements of the tiger and the crane. In Imperial China, a tiger was the personification of war and often represented the highest army general (or present day defense secretary),[186] while the emperor and empress were represented by a dragon and phoenix, respectively. The White Tiger (Chinese: 白虎; pinyin: Bái Hǔ) is one of the Four Symbols of the Chinese constellations. It is sometimes called the White Tiger of the West (Chinese: 西方白虎), and it represents the west and the autumn season.[186]

The tiger's tail appears in stories from countries including China and Korea, it being generally inadvisable to grasp a tiger by the tail.[187][188] In Korean myth and culture, the tiger is regarded as a guardian that drives away evil spirits and a sacred creature that brings good luck – the symbol of courage and absolute power. For the people who live in and around the forests of Korea, the tiger considered the symbol of the Mountain Spirit or King of mountain animals. So, Koreans also called the tigers "San Gun" (산군) means Mountain Lord.[189]

In Buddhism, the tiger is one of the Three Senseless Creatures, symbolising anger, with the monkey representing greed and the deer lovesickness.[186] The Tungusic peoples considered the Siberian tiger a near-deity and often referred to it as "Grandfather" or "Old man". The Udege and Nanai called it "Amba". The Manchu considered the Siberian tiger as "Hu Lin," the king.[56] In Hinduism, the god Shiva wears and sits on tiger skin.[190] The ten-armed warrior goddess Durga rides the tigress (or lioness) Damon into battle. In southern India the god Ayyappan was associated with a tiger.[191] Dingu-Aneni is the god in North-East India is also associated with tiger.[192] The weretiger replaces the werewolf in shapeshifting folklore in Asia;[193] in India they were evil sorcerers, while in Indonesia and Malaysia they were somewhat more benign.[194] In Greco-Roman tradition, the tiger was depicted being ridden by the god Dionysus.[195]

William Blake's first printing of The Tyger, 1794

Literature and media

In the Hindu epic Mahabharata, the tiger is fiercer and more ruthless than the lion.[196] William Blake's poem in his Songs of Experience (1794), titled "The Tyger", portrays the tiger as a menacing and fearful animal.[197] In Rudyard Kipling's 1894 The Jungle Book, the tiger Shere Khan is the mortal enemy of the human protagonist Mowgli.[197] Yann Martel's 2001 Booker Prize winning novel Life of Pi, features the title character surviving shipwreck for months on a small boat with a large Bengal tiger while avoiding being eaten. The story was adapted in Ang Lee's 2012 feature film of the same name.[198]

Friendly tiger characters include Tigger in A. A. Milne's Winnie-the-Pooh and Hobbes of the comic strip Calvin and Hobbes, both represented as stuffed animals come to life.[199] Tony the Tiger is a famous mascot for Kellogg's breakfast cereal Frosted Flakes, known for his catchphrase "They're Gr-r-reat!".[200]

Heraldry and emblems

An early silver coin of king Uttama Chola found in Sri Lanka shows the Chola Tiger sitting between the emblems of Pandyan and Chera

The tiger is one of the animals displayed on the Pashupati seal of the Indus Valley civilisation. The tiger was the emblem of the Chola Dynasty and was depicted on coins, seals and banners.[201] The seals of several Chola copper coins show the tiger, the Pandyan emblem fish and the Chera emblem bow, indicating that the Cholas had achieved political supremacy over the latter two dynasties. Gold coins found in Kavilayadavalli in the Nellore district of Andhra Pradesh have motifs of the tiger, bow and some indistinct marks.[202] The tiger symbol of Chola Empire was later adopted by the Liberation Tigers of Tamil Eelam and the tiger became a symbol of the unrecognised state of Tamil Eelam and Tamil independence movement.[203] The Bengal tiger is the national animal of India and Bangladesh.[204] The Malaysian tiger is the national animal of Malaysia.[205] The Siberian tiger is the national animal of South Korea. The Tiger is featured on the logo of the Delhi Capitals IPL team.

In European heraldry, the tyger, a depiction of a tiger as imagined by European artists, is among the creatures used in charges and supporters. This creature has several notable differences from real tigers, lacking stripes and having a leonine tufted tail and a head terminating in large, pointed jaws. A more realistic tiger entered the heraldic armory through the British Empire's expansion into Asia, and is referred to as the Bengal tiger to distinguish it from its older counterpart. The Bengal tiger is not a common creature in heraldry, but is used as a supporter in the arms of Bombay and emblazoned on the shield of the University of Madras.[206]

Tiger: Brief Summary

provided by wikipedia EN

The tiger (Panthera tigris) is the largest living cat species and a member of the genus Panthera. It is most recognisable for its dark vertical stripes on orange fur with a white underside. An apex predator, it primarily preys on ungulates, such as deer and wild boar. It is territorial and generally a solitary but social predator, requiring large contiguous areas of habitat to support its requirements for prey and rearing of its offspring. Tiger cubs stay with their mother for about two years and then become independent, leaving their mother's home range to establish their own.

The tiger was first scientifically described in 1758. It once ranged widely from the Eastern Anatolia Region in the west to the Amur River basin in the east, and in the south from the foothills of the Himalayas to Bali in the Sunda Islands. Since the early 20th century, tiger populations have lost at least 93% of their historic range and have been extirpated from Western and Central Asia, the islands of Java and Bali, and in large areas of Southeast and South Asia and China. What remains of the range where tigers still roam free is fragmented, stretching in spots from Siberian temperate forests to subtropical and tropical forests on the Indian subcontinent, Indochina and a single Indonesian island, Sumatra.

The tiger is listed as Endangered on the IUCN Red List. As of 2015, the global wild tiger population was estimated to number between 3,062 and 3,948 mature individuals, with most populations living in small isolated pockets. India currently hosts the largest tiger population. Major reasons for population decline are habitat destruction, habitat fragmentation and poaching. Tigers are also victims of human–wildlife conflict, due to encroachment in countries with a high human population density.

The tiger is among the most recognisable and popular of the world's charismatic megafauna. It featured prominently in the ancient mythology and folklore of cultures throughout its historic range and continues to be depicted in modern films and literature, appearing on many flags, coats of arms and as mascots for sporting teams. The tiger is the national animal of India, Bangladesh, Malaysia and South Korea.
