The Asiatic Lion (Panthera leo persica) is a subspecies of the lion which survives today only in India. They ranged once from the Mediterranean to India, covering most of Southwest Asia and hence it is also known as the Persian lion.

The current wild population consists of about 350 individuals restricted to the Gir Forest in the state of Gujarat, India.

The historic distribution included the Caucasus to Yemen and from Macedonia to present-day India through Iran, Afghanistan and Pakistan through to the borders of Bangladesh.

[edit] Biology and behaviour

Compared to their African cousins, Asiatic lions have shaggier coats, with a longer tassel on the end of the tail and longer tufts of hair on the elbows. Both sexes have a distinctive fold of skin that runs along the belly. Males are 1.7-2.2 m long and weigh 150-225 kg, while females are 1.4-1.7 m in length and weigh in at 100-150 kg. The largest known wild male was exactly 3 m (9.9 ft) in length.^[1]

Asian lions are highly social animals, living in units called prides. Asiatic lion prides are smaller than those of African lions, with an average of only two females. The African pride has an average of four to six. The Asian males are less social and only associate with the pride when mating or on a large kill. It has been suggested that this may be because their prey animals are smaller than those in Africa, requiring fewer hunters to tackle them.^[2]

[edit] Status

The Gir Forest National Park of western India has about 359 lions (as of April 2006) which live in a 1,412 km² (558 square miles) sanctuary covered with scrub and open deciduous forest habitats. The population in 1907 consisted of only 13 lions and the Nawab of Junagadh gave them complete protection.

The Bengal Tiger, which is the other large cat on the Indian subcontinent, is no longer found in the area occupied by the Lion, seeing as it prefers dense forests to the open plains favored by lions.

[edit] Inbreeding concerns

The wild population of more than 360 Asiatic Lions is thought to be derived from just 13 individuals and thus was widely thought to be highly inbred. Many studies have reported that the inbred populations could be susceptible to diseases, and their sperm were deformed leading to infertility. In earlier studies Stephen O'Brien, a geneticist, had suggested that "If you do a DNA fingerprint, Asiatic lions actually look like identical twins... because they descend from as few as a dozen individuals that was all left at the turn of the 20th century."^[3] This makes them especially vulnerable to diseases, and causes 70% to 80% of sperm to be deformed — a ratio that can lead to infertility when lions are further inbred in captivity.

A subsequent study suggested that the low genetic variability may have been a feature of the original population and not a result of inbreeding in recent times. They also show that the variability in immunotypes is close to that of the tiger population and that there are no spermatazoal abnormalities in the current population of Asiatic Lions.^[4][5] The results of the study have been questioned due the use of RAPD techniques which are unsuitable for population genetics research.^[6]

The population figure of 13 Asiatic lions at the turn of 1900s is inaccurate according to some reports and is said to have been publicized to discourage hunting. Census data from that time indicates that the population was closer to 100.^[7] Hunting of lions was a popular sport with the British Colonialists and Indian Royalty, and all other lions in India had been exterminated by then.

[edit] Threats to the subspecies

Lions are poisoned for attacking livestock. Some of the other major threats include floods, fires and epidemics. Their restricted range makes them especially vulnerable.

Nearly 15,000 to 20,000 open wells dug by farmers in the area for irrigation have also acted as traps with many lions drowning. Suggestions for walls around the wells as well as the use of "Drilled Tube wells" have been made.

Farmers on the periphery of the Gir Forest frequently use crude and illegal electrical fences by powering them with high voltage overhead power lines. These are usually intended to protect their crops from Nilgai but lions and other wildlife are also killed.

The biggest threat faced by the Gir Forest is the presence of Maldharis.^{[citation needed]} These communities are vegetarian and do not indulge in poaching because they are basically pasturalists, with an average of 50 cattle (mainly "Gir Cow") per family. The areas around Maldhari settlements, nesses, are overgrazed. This habitat destruction by the cattle and the firewood requirements of the populace reduces the natural prey base and endangers the lions. The lions are in turn forced by the lack of natural prey to shift to killing cattle and are in turn targeted by the people.

[edit] Genetic pollution in captive Asiatic lions

Native captive Asiatic Lions in Indian zoos till recently were genetically polluted with genes of African Lions confiscated from circuses. This latter group was randomly hybridized with Asiatic lions, leading to widespread genetic pollution in the captive Asiatic lion population. Once discovered, this led to the complete shut down of the European (EEP) and the American endangered species registered breeding programs (SSP) for Asiatic Lions as the founder animals originally imported from India were ascertained to be genetically polluted with the genes of African lions. Since then India has corrected its mistake and now breeds only pure native Asiatic Lions, and has helped revive the European endangered species registered breeding program (EEP) for Asiatic Lions. However, the American SSP which completely shut down in early 1980s has yet to receive pure bred Asiatic Lions from India to form a new founder population for breeding in zoos on the American continent.^{[8][6][9][10]}

[edit] Reintroduction

Main articles: Asiatic Lion Reintroduction Project and Kuno Wildlife Sanctuary

Work has been going on over the past decade to establish the world's second completely removed population of the wild free ranging Asiatic Lions. Wildlife Institute of India researchers confirmed that the Palpur-Kuno Wildlife Sanctuary is the most promising location to re-establish a free ranging population of the Asiatic lions and certified it ready to receive its first batch of translocated lions^[11] from Gir Wildlife Sanctuary where they are highly overpopulated. Kuno Wildlife Sanctuary was selected as the reintroduction site for critically endangered Asiatic lion because it is in the former range of the lions before it was hunted into extinction in about 1873.^[12].

[edit] Asiatic Lions in Europe and Southwest Asia

Lions were once found in Europe. Aristotle and Herodotus wrote that lions were found in the Balkans. When King Xerxes of Persia advanced through Macedon in 480 BC, several of his baggage camels were killed by lions. Lions are believed to have died out within the borders of present-day Greece around AD 80-100.

The European population is sometimes considered part of the Asiatic lion (Panthera leo persica) group, but others consider it a separate subspecies, the European lion (Panthera leo europaea) or a last remnant of the Cave lion (Panthera leo spelaea).

Lions were found in the Caucasus until the 10th century. This was the northernmost population of lions and the only place in the former Soviet Union's territory that lions lived in historic times. These lions became extinct in Armenia around the year 100 and in Azerbaijan and southwest Russia during the 10th century. The region was also inhabited by the Caspian Tiger and the Persian leopard apart from Asiatic Cheetahs (Acinonyx jubatus venaticus) introduced by Armenian princes for hunting. The last tiger was shot in 1932 near Prishib village in Talis, Azerbaijan Republic. The principal reasons for the disappearance of these cats was their extermination as predators. The prey for large cats in the region included the wisent, elk, aurochs, tarpan, deer and other ungulates.

Lions remained widespread elsewhere until the mid-19th century when the advent of firearms led to its extinction over large areas. The last sighting of a live Asiatic Lion in Iran was in 1941 (between Shiraz and Jahrom, Fars province). In 1944, the corpse of a lioness was found on the banks of Karun river, Khuzestan province, Iran. There are no subsequent reliable reports from Iran.^[13] By the late 19th century the lion had disappeared from Turkey.^[14][15]

[edit] The Barbary Lion

Main article: Barbary Lion

In 1968, a study of the skulls of the extinct Barbary (North African), extinct Cape, Asiatic, and African lions showed that the same skull characteristics - the very narrow bar - that existed in the Barbary and Asiatic lion skulls.^{[citation needed]} This shows that there may have been a close relationship between the lions from Northernmost Africa and Asia. It is also believed that the South European lion that became extinct around AD 80-100, could have represented the connecting link between the North African and Asiatic lions. It is believed that Barbary lions possessed the same belly fold (hidden under their manes) that are seen in the Asian lions today.

[edit] Asiatic Lion in Culture

"Bharat Mata" ("Mother India"), National personification of India, depicted with an Asiatic / Indian lion at her side

This is the famous original sandstone sculpted Lion Capital of Ashoka preserved at Sarnath Museum which was originally erected around 250 BCE atop an Ashoka Pillar at Sarnath. The angle from which this picture has been taken, minus the inverted bell-shaped lotus flower, has been adopted as the National Emblem of India showing the Horse on the left and the Bull on the right of the Ashoka Chakra in the circular base on which the four Indian / Asiatic lions are standing back to back. On the far side there is an Elephant and a Lion instead. The wheel "Ashoka Chakra" from its base has been placed onto the center of the National Flag of India.

• Found famously on numerous Flags and Coat of Arms all across Asia and Europe, the Asiatic Lions also stand firm on the National Emblem of India.

• Narasimha ("man-lion") (also spelt as Narasingh, Narasinga) is described as an incarnation (avatara) of Vishnu within the Puranic texts of Hinduism and is worshiped as "Lion God" thus Indian or Asiatic Lions which were commonly found throughout most of India in ancient times are considered sacred by all Hindus in India.

• Singh is an ancient Indian vedic name meaning "Lion" (Asiatic Lion), dating back over 2000 years to ancient India. It was originally only used by Rajputs a Hindu Kshatriya or military caste in India since the 7th Century. After the birth of the Khalsa brotherhood in 1699, the Sikhs also adopted the name "Singh" due to the wishes of Guru Gobind Singh. Along with millions of Hindu Rajputs today, it is also used by up to 10 million Sikhs worldwide.^[16][17]

• The island nation of Singapore (Singapura) derives its name from the Malay words singa (lion) and pura (city), which in turn is from the Sanskrit िंसह siṃha and पुर pura.^[18] According to the Malay Annals, this name was given by a 14th century Sumatran Malay prince named Sang Nila Utama, who, on alighting the island after a thunderstorm, spotted an auspicious beast on shore that his chief minister identified as a lion (Asiatic Lion).^[19] Recent studies of Singapore indicate that lions have never lived there, and the beast seen by Sang Nila Utama was likely a tiger.

• The Asiatic lion makes repeated appearances in the Bible, most notably as having fought Samson in the Book of Judges.

• The Asiatic lion is the basis of the lion dances that form part of the traditional Chinese New Year celebrations, and of similar customs in other Asian countries.
