Historical and present distribution of the lion in Africa, Asia and Europe

The lion (Panthera leo) is a species in the family Felidae and a member of the genus Panthera . It has a muscular, deep-chested body, short, rounded head, round ears, and a hairy tuft at the end of its tail. It is sexually dimorphic; adult male lions have a prominent mane. With a typical head-to-body length of 184–208 cm (72–82 in) they are larger than females at 160–184 cm (63–72 in). It is a social species, forming groups called prides. A lion pride consists of a few adult males, related females and cubs. Groups of female lions usually hunt together, preying mostly on large ungulates. The lion is an apex and keystone predator; although some lions scavenge when opportunities occur and have been known to hunt humans, the species typically does not.

Contents

Typically, the lion inhabits grasslands and savannas, but is absent in dense forests. It is usually more diurnal than other big cats, but when persecuted it adapts to being active at night and at twilight. In the Pleistocene, the lion ranged throughout Eurasia, Africa and North America, but today it has been reduced to fragmented populations in sub-Saharan Africa and one critically endangered population in western India. It has been listed as Vulnerable on the IUCN Red List since 1996 because populations in African countries have declined by about 43% since the early 1990s. Lion populations are untenable outside designated protected areas. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are the greatest causes for concern.

One of the most widely recognised animal symbols in human culture, the lion has been extensively depicted in sculptures and paintings, on national flags, and in contemporary films and literature. Lions have been kept in menageries since the time of the Roman Empire and have been a key species sought for exhibition in zoological gardens across the world since the late 18th century. Cultural depictions of lions were prominent in the Upper Paleolithic period; carvings and paintings from the Lascaux and Chauvet Caves in France have been dated to 17,000 years ago, and depictions have occurred in virtually all ancient and medieval cultures that coincided with the lion's former and current ranges.

Etymology

The word 'lion' is derived from Latin : leo [4] and Ancient Greek : λέων (leon). [5] The word lavi (Hebrew : לָבִיא) may also be related. [6] The generic name Panthera is traceable to the classical Latin word 'panthēra' and the ancient Greek word πάνθηρ 'panther'. [7] Panthera is phonetically similar to the Sanskrit word पाण्डर pând-ara meaning 'pale yellow, whitish, white'. [8]

Felis leo was the scientific name used by Carl Linnaeus in 1758, who described the lion in his work Systema Naturae . [3] The genus name Panthera was coined by German naturalist Lorenz Oken in 1816. [13] Between the mid-18th and mid-20th centuries, 26 lion specimens were described and proposed as subspecies, of which 11 were recognised as valid in 2005. [2] They were distinguished mostly by the size and colour of their manes and of their skins. [14]

Subspecies

In the 19th and 20th centuries, several lion type specimens were described and proposed as subspecies, with about a dozen recognised as valid taxa until 2017. [2] Between 2008 and 2016, IUCN Red List assessors used only two subspecific names: P. l. leo for African lion populations and P. l. persica for the Asiatic lion population. [1] [15] [16] In 2017, the Cat Classification Task Force of the Cat Specialist Group revised lion taxonomy, and recognises two subspecies based on results of several phylogeographic studies on lion evolution, namely: [17]

Lion samples from some parts of the Ethiopian Highlands cluster genetically with those from Cameroon and Chad, while lions from other areas of Ethiopia cluster with samples from East Africa. Researchers therefore assume Ethiopia is a contact zone between the two subspecies. [20] Genome-wide data of a wild-born historical lion sample from Sudan showed that it clustered with P. l. leo in mtDNA-based phylogenies, but with a high affinity to P. l. melanochaita. This result suggested that the taxonomic position of lions in Central Africa may require revision. [21]

Phylogenetic analyses of nuclear and mitochondrial DNA from all Felidae species indicate that their evolutionary radiation began in Asia in the Miocene around 14.45 to 8.38 million years ago to 16.76 to 6.46 million years ago. The Panthera lineage is estimated to have genetically diverged from the common ancestor of the Felidae around 9.32 to 4.47 million years ago to 11.75 to 0.97 million years ago. [9] [35] [36] The geographic origin of the Panthera is most likely northern Central Asia. [37] Results of analyses differ in the phylogenetic relationship of the lion; it was thought to form a sister group with the jaguar (P. onca) that diverged 3.46 to 1.22 million years ago, [9] but also with the leopard (P. pardus) that diverged 3.1 to 1.95 million years ago [11] [12] to 4.32 to 0.02 million years ago. Hybridisation between lion and snow leopard (P. uncia) ancestors possibly continued until about 2.1 million years ago. [36] The lion-leopard clade was distributed in the Asian and African Palearctic since at least the early Pliocene. [37] The earliest fossils recognisable as lions were found at Olduvai Gorge in Tanzania and are estimated to be up to 2 million years old. [35]

Estimates for the divergence time of the modern and cave lion lineages range from 529,000 to 392,000 years ago based on mutation rate per generation time of the modern lion. There is no evidence for gene flow between the two lineages, indicating that they did not share the same geographic area. [21] The Eurasian and American cave lions became extinct at the end of the last glacial period without mitochondrial descendants on other continents. [29] [38] [39] The modern lion was probably widely distributed in Africa during the Middle Pleistocene and started to diverge in sub-Saharan Africa during the Late Pleistocene. Lion populations in East and Southern Africa became separated from populations in West and North Africa when the equatorial rainforest expanded 183,500 to 81,800 years ago. [40] They shared a common ancestor probably between 98,000 and 52,000 years ago. [21] Due to the expansion of the Sahara between 83,100 and 26,600 years ago, lion populations in West and North Africa became separated. As the rainforest decreased and thus gave rise to more open habitats, lions moved from West to Central Africa. Lions from North Africa dispersed to southern Europe and Asia between 38,800 and 8,300 ago. [40]

Extinction of lions in southern Europe, North Africa and the Middle East interrupted gene flow between lion populations in Asia and Africa. Genetic evidence revealed numerous mutations in lion samples from East and Southern Africa, which indicates that this group has a longer evolutionary history than genetically less diverse lion samples from Asia and West and Central Africa. [41] A whole genome-wide sequence of lion samples showed that samples from West Africa shared alleles with samples from Southern Africa, and samples from Central Africa shared alleles with samples from Asia. This phenomenon indicates that Central Africa was a melting pot of lion populations after they had become isolated, possibly migrating through corridors in the Nile Basin during the early Holocene. [21]

Hybrids

In zoos, lions have been bred with tigers to create hybrids for the curiosity of visitors or for scientific purpose. [42] [43] The liger is bigger than a lion and a tiger, whereas most tigons are relatively small compared to their parents because of reciprocal gene effects. [44] [45] The leopon is a hybrid between a lion and leopard. [46]

Description

Skeleton

The lion is a muscular, deep-chested cat with a short, rounded head, a reduced neck and round ears. Its fur varies in colour from light buff to silvery grey, yellowish red and dark brown. The colours of the underparts are generally lighter. A new-born lion has dark spots, which fade as the cub reaches adulthood, although faint spots often may still be seen on the legs and underparts. The lion is the only member of the cat family that displays obvious sexual dimorphism. Males have broader heads and a prominent mane that grows downwards and backwards covering most of the head, neck, shoulders, and chest. The mane is typically brownish and tinged with yellow, rust and black hairs. [47] [48]

The tail of all lions ends in a dark, hairy tuft that in some lions conceals an approximately 5 mm (0.20 in)-long, hard "spine" or "spur" that is formed from the final, fused sections of tail bone. The functions of the spur are unknown. The tuft is absent at birth and develops at around 5 12 months of age. It is readily identifiable by the age of seven months. [49]

Of the living felid species, the lion is rivaled only by the tiger in length, weight, and height at the shoulder. [50] Its skull is very similar to that of the tiger, although the frontal region is usually more depressed and flattened, and has a slightly shorter postorbital region and broader nasal openings than those of the tiger. Due to the amount of skull variation in the two species, usually only the structure of the lower jaw can be used as a reliable indicator of species. [51] [52]

The size and weight of adult lions varies across global range and habitats. [53] [54] [55] [56] Accounts of a few individuals that were larger than average exist from Africa and India. [47] [57] [58] [59]

Mane

The male lion's mane is the most recognisable feature of the species. [14] It may have evolved around 320,000–190,000 years ago. [61] It starts growing when lions are about a year old. Mane colour varies and darkens with age; research shows its colour and size are influenced by environmental factors such as average ambient temperature. Mane length apparently signals fighting success in male–male relationships; darker-maned individuals may have longer reproductive lives and higher offspring survival, although they suffer in the hottest months of the year. The presence, absence, colour and size of the mane are associated with genetic precondition, sexual maturity, climate and testosterone production; the rule of thumb is that a darker, fuller mane indicates a healthier animal. In Serengeti National Park, female lions favour males with dense, dark manes as mates. Male lions usually aim for the backs or hindquarters of rivals, rather than their necks. [62] [63] Cool ambient temperature in European and North American zoos may result in a heavier mane. [64] Asiatic lions usually have sparser manes than average African lions. [65]

Almost all male lions in Pendjari National Park are either maneless or have very short manes. [66] Maneless lions have also been reported in Senegal, in Sudan's Dinder National Park and in Tsavo East National Park, Kenya. [67] The original male white lion from Timbavati in South Africa was also maneless. The hormone testosterone has been linked to mane growth; castrated lions often have little to no mane because the removal of the gonads inhibits testosterone production. [68] Increased testosterone may be the cause of maned lionesses reported in northern Botswana. [69]

Colour variation

The white lion is a rare morph with a genetic condition called leucism which is caused by a double recessive allele. It is not albino; it has normal pigmentation in the eyes and skin. White lions have occasionally been encountered in and around Kruger National Park and the adjacent Timbavati Private Game Reserve in eastern South Africa. They were removed from the wild in the 1970s, thus decreasing the white lion gene pool. Nevertheless, 17 births have been recorded in five prides between 2007 and 2015. [70] White lions are selected for breeding in captivity. [71] They have reportedly been bred in camps in South Africa for use as trophies to be killed during canned hunts. [72]

Distribution and habitat

African lions live in scattered populations across Sub-Saharan Africa. The lion prefers grassy plains and savannahs, scrub bordering rivers and open woodlands with bushes. It is absent from rainforest and rarely enters closed forest. On Mount Elgon, the lion has been recorded up to an elevation of 3,600 m (11,800 ft) and close to the snow line on Mount Kenya. [47] Lions occur in savannah grasslands with scattered acacia trees, which serve as shade. [73] The Asiatic lion now survives only in and around Gir National Park in Gujarat, western India. Its habitat is a mixture of dry savannah forest and very dry, deciduous scrub forest. [15]

Historical range

In Africa, the range of the lion originally spanned most of the central rainforest zone and the Sahara desert. [74] In the 1960s, it became extinct in North Africa, except in the southern part of Sudan. [75] [76] [77]

In southern Europe and Asia, the lion once ranged in regions where climatic conditions supported an abundance of prey. [78] In Greece, it was common as reported by Herodotus in 480 BC; it was considered rare by 300 BC and extirpated by AD 100. [47] It was present in the Caucasus until the 10th century. [52] It lived in Palestine until the Middle Ages, and in Southwest Asia until the late 19th century. By the late 19th century, it had been extirpated in most of Turkey. [79] The last live lion in Iran was sighted in 1942 about 65 km (40 mi) northwest of Dezful, [80] although the corpse of a lioness was found on the banks of the Karun river in Khūzestān Province in 1944. [81] It once ranged from Sind and Punjab in Pakistan to Bengal and the Narmada River in central India. [82]

Behaviour and ecology

Lions spend much of their time resting; they are inactive for about 20 hours per day. [83] Although lions can be active at any time, their activity generally peaks after dusk with a period of socialising, grooming and defecating. Intermittent bursts of activity continue until dawn, when hunting most often takes place. They spend an average of two hours a day walking and 50 minutes eating. [84]

Group organisation

The lion is the most social of all wild felid species, living in groups of related individuals with their offspring. Such a group is called a "pride". Groups of male lions are called "coalitions". [85] Females form the stable social unit in a pride and do not tolerate outside females. [86] Membership changes only with the births and deaths of lionesses, [87] although some females leave and become nomadic. [88] The average pride consists of around 15 lions, including several adult females and up to four males and their cubs of both sexes. Large prides, consisting of up to 30 individuals, have been observed. [89] The sole exception to this pattern is the Tsavo lion pride that always has just one adult male. [90] Male cubs are excluded from their maternal pride when they reach maturity at around two or three years of age. [88]

Some lions are "nomads" that range widely and move around sporadically, either in pairs or alone. [85] Pairs are more frequent among related males who have been excluded from their birth pride. A lion may switch lifestyles; nomads can become residents and vice versa. [91] Interactions between prides and nomads tend to be hostile, although pride females in estrus allow nomadic males to approach them. [92] Males spend years in a nomadic phase before gaining residence in a pride. [93] A study undertaken in the Serengeti National Park revealed that nomadic coalitions gain residency at between 3.5 and 7.3 years of age. [94] In Kruger National Park, dispersing male lions move more than 25 km (16 mi) away from their natal pride in search of their own territory. Female lions stay closer to their natal pride. Therefore, female lions in an area are more closely related to each other than male lions in the same area. [95]

The area occupied by a pride is called a "pride area" whereas that occupied by a nomad is a "range". [85] Males associated with a pride tend to stay on the fringes, patrolling their territory. The reasons for the development of sociality in lionesses—the most pronounced in any cat species—are the subject of much debate. Increased hunting success appears to be an obvious reason, but this is uncertain upon examination; coordinated hunting allows for more successful predation but also ensures non-hunting members reduce per capita calorific intake. Some females, however, take a role raising cubs that may be left alone for extended periods. Members of the pride tend to regularly play the same role in hunts and hone their skills. The health of the hunters is the primary need for the survival of the pride; hunters are the first to consume the prey at the site it is taken. Other benefits include possible kin selection; sharing food within the family; protecting the young, maintaining territory and individual insurance against injury and hunger. [57]

Both males and females defend the pride against intruders, but the male lion is better-suited for this purpose due to its stockier, more powerful build. Some individuals consistently lead the defence against intruders, while others lag behind. [96] Lions tend to assume specific roles in the pride; slower-moving individuals may provide other valuable services to the group. [97] Alternatively, there may be rewards associated with being a leader that fends off intruders; the rank of lionesses in the pride is reflected in these responses. [98] The male or males associated with the pride must defend their relationship with the pride from outside males who may attempt to usurp them. [91]

Asiatic lion prides differ in group composition. Male Asiatic lions are solitary or associate with up to three males, forming a loose pride while females associate with up to 12 other females, forming a stronger pride together with their cubs. Female and male lions associate only when mating. [99] Coalitions of males hold territory for a longer time than single lions. Males in coalitions of three or four individuals exhibit a pronounced hierarchy, in which one male dominates the others and mates more frequently. [100]

Hunting and diet

The lion is a generalist hypercarnivore [101] and is considered to be both an apex and keystone predator due to its wide prey spectrum. [102] Its prey consists mainly of mammals—particularly ungulates—weighing 190–550 kg (420–1,210 lb) with a preference for blue wildebeest, plains zebra, African buffalo, gemsbok and giraffe. Lions also hunt common warthog depending on availability, although the species is below the preferred weight range. [103] In India, sambar deer and chital are the most commonly recorded wild prey, [48] [103] [104] while domestic livestock may contribute significantly to their diet. [104] They usually avoid fully grown adult elephants, rhinoceroses and hippopotamus, as well as small prey like dik-dik, hyrax, hare and monkey. [103] [105] Unusual prey items include porcupines and small reptiles. Lions kill other predators such as leopard, cheetah and spotted hyena but seldom consume them. [106]

Young lions first display stalking behaviour at around three months of age, although they do not participate in hunting until they are almost a year old and begin to hunt effectively when nearing the age of two. [107] Single lions are capable of bringing down zebra and wildebeest, while larger prey like buffalo and giraffe are riskier. [91] In Chobe National Park, large prides have been observed hunting African bush elephants up to around 15 years old in exceptional cases, with most of the victims being juveniles or subadults. [108] [109] In typical hunts, each lioness has a favoured position in the group, either stalking prey on the "wing", then attacking, or moving a smaller distance in the centre of the group and capturing prey fleeing from other lionesses. Males attached to prides do not usually participate in group hunting. [110] Some evidence suggests, however, that males are just as successful as females; they are typically solo hunters who ambush prey in small bushland. [111]

Lions are not particularly known for their stamina; for instance, a lioness' heart comprises only 0.57% of her body weight and a male's is about 0.45% of his body weight, whereas a hyena's heart comprises almost 1% of its body weight. [112] Thus, lions run quickly only in short bursts [113] and need to be close to their prey before starting the attack. They take advantage of factors that reduce visibility; many kills take place near some form of cover or at night. [114] The lion's attack is short and powerful; they attempt to catch prey with a fast rush and final leap. They usually pull it down by the rump and kill by a strangling bite to the throat. They also kill prey by enclosing its mouth and nostrils in their jaws. [115]

Lions typically consume prey at the location of the hunt but sometimes drag large prey into cover. [116] They tend to squabble over kills, particularly the males. Cubs suffer most when food is scarce but otherwise all pride members eat their fill, including old and crippled lions, which can live on leftovers. [91] Large kills are shared more widely among pride members. [117] An adult lioness requires an average of about 5 kg (11 lb) of meat per day while males require about 7 kg (15 lb). [118] Lions gorge themselves and eat up to 30 kg (66 lb) in one session; [81] if it is unable to consume all of the kill, it rests for a few hours before continuing to eat. On hot days, the pride retreats to shade with one or two males standing guard. [116] Lions defend their kills from scavengers such as vultures and hyenas. [91]

Lions scavenge on carrion when the opportunity arises; they scavenge animals dead from natural causes such as disease or those that were killed by other predators. Scavenging lions keep a constant lookout for circling vultures, which indicate the death or distress of an animal. [119] Most carrion on which both hyenas and lions feed upon are killed by hyenas rather than lions. [56] Carrion is thought to provide a large part of lion diet. [120]

Lions and spotted hyenas occupy a similar ecological niche and where they coexist they compete for prey and carrion; a review of data across several studies indicates a dietary overlap of 58.6%. [121] Lions typically ignore spotted hyenas unless the lions are on a kill or are being harassed by the hyenas, while the latter tend to visibly react to the presence of lions, with or without the presence of food. Lions seize the kills of spotted hyenas; in the Ngorongoro crater it is common for lions to subsist largely on kills stolen from hyenas, causing the hyenas to increase their kill rate. [122] In Botswana's Chobe National Park, the situation is reversed; hyenas frequently challenge lions and steal their kills, obtaining food from 63% of all lion kills. [123] When confronted on a kill by lions, spotted hyenas may either leave or wait patiently at a distance of 30–100 m (100–330 ft) until the lions have finished. [124] Hyenas are bold enough to feed alongside lions and to force the lions off a kill. The two species attack one another even when there is no food involved for no apparent reason. [125] [126] Lion predation can account for up to 71% of hyena deaths in Etosha National Park. Spotted hyenas have adapted by frequently mobbing lions that enter their territories. [127] When the lion population in Kenya's Masai Mara National Reserve declined, the spotted hyena population increased rapidly. [128] Experiments on captive spotted hyenas show that specimens without prior experience with lions act indifferently to the sight of them, but will react fearfully to lion scent. [122]

Lions tend to dominate cheetahs and leopards, steal their kills and kill their cubs and even adults when given the chance. [129] Cheetahs in particular often lose their kills to lions or other predators. [130] A study in the Serengeti ecosystem revealed that lions killed at least 17 of 125 cheetah cubs born between 1987 and 1990. [131] Cheetahs avoid their competitors by using different temporal and habitat niches. [132] Leopards are able to take refuge in trees; lionesses, however, occasionally attempt to retrieve leopard kills from trees. [133] Lions similarly dominate African wild dogs, taking their kills and preying on young and rarely adult dogs. Population densities of wild dogs are low in areas where lions are more abundant. [134] However, there are a few reported cases of old and wounded lions falling prey to wild dogs. [135] [136] Lions also charge at Nile crocodiles; depending on the size of the crocodile and the lion, either animal can lose their kills to the other. Lions have been observed killing crocodiles that ventured onto land. [137] Crocodiles may also kill and eat lions, evidenced by the occasional lion claw found in crocodile stomachs. [138]

Reproduction and life cycle

Most lionesses reproduce by the time they are four years of age. [139] Lions do not mate at a specific time of year and the females are polyestrous. [140] Like those of other cats, the male lion's penis has spines that point backward. During withdrawal of the penis, the spines rake the walls of the female's vagina, which may cause ovulation. [141] [142] A lioness may mate with more than one male when she is in heat. [143] Generation length of the lion is about seven years. [144] The average gestation period is around 110 days; [140] the female gives birth to a litter of between one and four cubs in a secluded den, which may be a thicket, a reed-bed, a cave, or some other sheltered area, usually away from the pride. She will often hunt alone while the cubs are still helpless, staying relatively close to the den. [145] Lion cubs are born blind; their eyes open around seven days after birth. They weigh 1.2–2.1 kg (2.6–4.6 lb) at birth and are almost helpless, beginning to crawl a day or two after birth and walking around three weeks of age. [146] To avoid a buildup of scent attracting the attention of predators, the lioness moves her cubs to a new den site several times a month, carrying them one-by-one by the nape of the neck. [145]

Usually, the mother does not integrate herself and her cubs back into the pride until the cubs are six to eight weeks old. [145] Sometimes this introduction to pride life occurs earlier, particularly if other lionesses have given birth at about the same time. [91] [147] When first introduced to the rest of the pride, lion cubs lack confidence when confronted with adults other than their mother. They soon begin to immerse themselves in the pride life, however, playing among themselves or attempting to initiate play with the adults. [147] Lionesses with cubs of their own are more likely to be tolerant of another lioness's cubs than lionesses without cubs. Male tolerance of the cubs varies—one male could patiently let the cubs play with his tail or his mane, while another may snarl and bat the cubs away. [148]

Pride lionesses often synchronise their reproductive cycles and communal rearing and suckling of the young, which suckle indiscriminately from any or all of the nursing females in the pride. The synchronisation of births is advantageous because the cubs grow to being roughly the same size and have an equal chance of survival, and sucklings are not dominated by older cubs. [91] [147] Weaning occurs after six or seven months. Male lions reach maturity at about three years of age and at four to five years are capable of challenging and displacing adult males associated with another pride. They begin to age and weaken at between 10 and 15 years of age at the latest. [149]

When one or more new males oust the previous males associated with a pride, the victors often kill any existing young cubs, perhaps because females do not become fertile and receptive until their cubs mature or die. Females often fiercely defend their cubs from a usurping male but are rarely successful unless a group of three or four mothers within a pride join forces against the male. [150] Cubs also die from starvation and abandonment, and predation by leopards, hyenas and wild dogs. [136] [91] Up to 80% of lion cubs will die before the age of two. [151] Both male and female lions may be ousted from prides to become nomads, although most females usually remain with their birth pride. When a pride becomes too large, however, the youngest generation of female cubs may be forced to leave to find their own territory. When a new male lion takes over a pride, adolescents both male and female may be evicted. [152] Lions of both sexes may be involved in group homosexual and courtship activities; males will also head-rub and roll around with each other before simulating sex together. [153] [154]

Although adult lions have no natural predators, evidence suggests most die violently from attacks by humans or other lions. [155] Lions often inflict serious injuries on members of other prides they encounter in territorial disputes or members of the home pride when fighting at a kill. [156] Crippled lions and cubs may fall victim to hyenas and leopards or be trampled by buffalo or elephants. Careless lions may be maimed when hunting prey. [157]

Ticks commonly infest the ears, neck and groin regions of lions. [158] [159] Adult forms of several species of the tapeworm genus Taenia have been isolated from lion intestines, having been ingested as larvae in antelope meat. [160] Lions in the Ngorongoro Crater were afflicted by an outbreak of stable fly ( Stomoxys calcitrans ) in 1962; this resulted in lions becoming emaciated and covered in bloody, bare patches. Lions sought unsuccessfully to evade the biting flies by climbing trees or crawling into hyena burrows; many died or migrated and the local population dropped from 70 to 15 individuals. [161] A more recent outbreak in 2001 killed six lions. [162]

Captive lions have been infected with canine distemper virus (CDV) since at least the mid 1970s. [163] CDV is spread by domestic dogs and other carnivores; a 1994 outbreak in Serengeti National Park resulted in many lions developing neurological symptoms such as seizures. During the outbreak, several lions died from pneumonia and encephalitis. [164] Feline immunodeficiency virus and lentivirus also affect captive lions. [165] [166]

Communication

Head rubbing among pride members is a common social behaviour

When resting, lion socialisation occurs through a number of behaviours; the animal's expressive movements are highly developed. The most common peaceful, tactile gestures are head rubbing and social licking, [167] which have been compared with the role of allogrooming among primates. [168] Head rubbing—nuzzling the forehead, face and neck against another lion—appears to be a form of greeting [169] and is seen often after an animal has been apart from others or after a fight or confrontation. Males tend to rub other males, while cubs and females rub females. [170] Social licking often occurs in tandem with head rubbing; it is generally mutual and the recipient appears to express pleasure. The head and neck are the most common parts of the body licked; this behaviour may have arisen out of utility because lions cannot lick these areas themselves. [171]

Lions have an array of facial expressions and body postures that serve as visual gestures. [172] A common facial expression is the "grimace face" or flehmen response, which a lion makes when sniffing chemical signals and involves an open mouth with bared teeth, raised muzzle, wrinkled nose closed eyes and relaxed ears. [173] Lions also use chemical and visual marking; males will spray and scrape plots of ground and objects within the territory. [172]

The lion's repertoire of vocalisations is large; variations in intensity and pitch appear to be central to communication. Most lion vocalisations are variations of growling, snarling, meowing and roaring. Other sounds produced include purring, puffing, bleating and humming. Roaring is used to advertise its presence. Lions most often roar at night, a sound that can be heard from a distance of 8 kilometres (5.0 mi). [174] They tend to roar in a very characteristic manner starting with a few deep, long roars that subside into a series of shorter ones. [175] [176]

Conservation

The lion is listed as Vulnerable on the IUCN Red List. [1]

In Africa

Several large and well-managed protected areas in Africa host large lion populations. Where an infrastructure for wildlife tourism has been developed, cash revenue for park management and local communities is a strong incentive for lion conservation. [1] Most lions now live in East and Southern Africa; their numbers are rapidly decreasing, and fell by an estimated 30–50% in the late half of the 20th century. Primary causes of the decline include disease and human interference. [1] In 1975, it was estimated that since the 1950s, lion numbers had decreased by half to 200,000 or fewer. [177] Estimates of the African lion population range between 16,500 and 47,000 living in the wild in 2002–2004. [178] [75]

In the Republic of the Congo, Odzala-Kokoua National Park was considered a lion stronghold in the 1990s. By 2014, no lions were recorded in the protected area so the population is considered locally extinct. [179] The West African lion population is isolated from the one in Central Africa, with little or no exchange of breeding individuals. In 2015, it was estimated that this population consists of about 400 animals, including fewer than 250 mature individuals. They persist in three protected areas in the region, mostly in one population in the W A P protected area complex, shared by Benin, Burkina Faso and Niger. This population is listed as Critically Endangered. [16] Field surveys in the WAP ecosystem revealed that lion occupancy is lowest in the W National Park, and higher in areas with permanent staff and thus better protection. [180]

A population occurs in Cameroon's Waza National Park, where between approximately 14 and 21 animals persisted as of 2009. [181] In addition, 50 to 150 lions are estimated to be present in Burkina Faso's Arly-Singou ecosystem. [182] In 2015, an adult male lion and a female lion were sighted in Ghana's Mole National Park. These were the first sightings of lions in the country in 39 years. [183] In the same year, a population of up to 200 lions that was previously thought to have been extirpated was filmed in the Alatash National Park, Ethiopia, close to the Sudanese border. [184] [185]

In 2005, Lion Conservation Strategies were developed for West and Central Africa, and or East and Southern Africa. The strategies seek to maintain suitable habitat, ensure a sufficient wild prey base for lions, reduce factors that lead to further fragmentation of populations, and make lion–human coexistence sustainable. [186] [187] Lion depredation on livestock is significantly reduced in areas where herders keep livestock in improved enclosures. Such measures contribute to mitigating human–lion conflict. [188]

In Asia

The last refuge of the Asiatic lion population is the 1,412 km2 (545 sq mi) Gir National Park and surrounding areas in the region of Saurashtra or Kathiawar Peninsula in Gujarat State, India. The population has risen from approximately 180 lions in 1974 to about 400 in 2010. [189] It is geographically isolated, which can lead to inbreeding and reduced genetic diversity. Since 2008, the Asiatic lion has been listed as Endangered on the IUCN Red List. [15] By 2015, the population had grown to 523 individuals inhabiting an area of 7,000 km2 (2,700 sq mi) in Saurashtra. [190] [191] [192] The Asiatic Lion Census conducted in 2017 recorded about 650 individuals. [193]

The presence of numerous human habitations close to the National Park results in conflict between lions, local people and their livestock. [194] [190] Some consider the presence of lions a benefit, as they keep populations of crop damaging herbivores in check. [195] The establishment of a second, independent Asiatic lion population in Kuno Wildlife Sanctuary, located in Madhya Pradesh was planned but in 2017, the Asiatic Lion Reintroduction Project seemed unlikely to be implemented. [196] [197]

Captive breeding

Lions imported to Europe before the middle of the 19th century were possibly foremost Barbary lions from North Africa, or Cape lions from Southern Africa. [198] Another 11 animals thought to be Barbary lions kept in Addis Ababa Zoo are descendants of animals owned by Emperor Haile Selassie. WildLink International in collaboration with Oxford University launched an ambitious International Barbary Lion Project with the aim of identifying and breeding Barbary lions in captivity for eventual reintroduction into a national park in the Atlas Mountains of Morocco. [199] However, a genetic analysis showed that the captive lions at Addis Ababa Zoo were not Barbary lions, but rather closely related to wild lions in Chad and Cameroon. [200]

In 1982, the Association of Zoos and Aquariums started a Species Survival Plan for the Asiatic lion to increase its chances of survival. In 1987, it was found that most lions in North American zoos were hybrids between African and Asiatic lions. [201] Breeding programs need to note origins of the participating animals to avoid cross-breeding different subspecies and thus reducing their conservation value. [202] Captive breeding of lions was halted to eliminate individuals of unknown origin and pedigree. Wild-born lions were imported to American zoos from Africa between 1989 and 1995. Breeding was continued in 1998 in the frame of an African lion Species Survival Plan. [203]

About 77% of the captive lions registered in the International Species Information System in 2006 were of unknown origin; these animals might have carried genes that are extinct in the wild and may therefore be important to the maintenance of the overall genetic variability of the lion. [64]

Interactions with humans

In zoos and circuses

Lions are part of a group of exotic animals that have been central to zoo exhibits since the late 18th century. Although many modern zoos are more selective about their exhibits, [204] there are more than 1,000 African and 100 Asiatic lions in zoos and wildlife parks around the world. They are considered an ambassador species and are kept for tourism, education and conservation purposes. [205] Lions can live over twenty years in captivity; a lion in Honolulu Zoo died at the age of 22 in August 2007. [206] His two sisters, born in 1986, also reached the age of 22. [207]

The first European "zoos" spread among noble and royal families in the 13th century, and until the 17th century were called seraglios; at that time they came to be called menageries, an extension of the cabinet of curiosities. They spread from France and Italy during the Renaissance to the rest of Europe. [208] In England, although the seraglio tradition was less developed, lions were kept at the Tower of London in a seraglio established by King John in the 13th century; [209] [210] this was probably stocked with animals from an earlier menagerie started in 1125 by Henry I at his hunting lodge in Woodstock, Oxfordshire, where according to William of Malmesbury lions had been stocked. [211]

Lions were kept in cramped and squalid conditions at London Zoo until a larger lion house with roomier cages was built in the 1870s. [212] Further changes took place in the early 20th century when Carl Hagenbeck designed enclosures with concrete "rocks", more open space and a moat instead of bars, more closely resembling a natural habitat. Hagenbeck designed lion enclosures for both Melbourne Zoo and Sydney's Taronga Zoo; although his designs were popular, the use of bars and caged enclosures prevailed in many zoos until the 1960s. [213] In the late 20th century, larger, more natural enclosures and the use of wire mesh or laminated glass instead of lowered dens allowed visitors to come closer than ever to the animals; some attractions such as the Cat Forest/Lion Overlook of Oklahoma City Zoological Park placed the den on ground level, higher than visitors. [214]

Lion taming has been part of both established circuses and individual acts such as Siegfried & Roy. The practice began in the early 19th century by Frenchman Henri Martin and American Isaac Van Amburgh, who both toured widely and whose techniques were copied by a number of followers. [215] Van Amburgh performed before Queen Victoria in 1838 when he toured Great Britain. Martin composed a pantomime titled Les Lions de Mysore ("the lions of Mysore"), an idea Amburgh quickly borrowed. These acts eclipsed equestrianism acts as the central display of circus shows and entered public consciousness in the early 20th century with cinema. In demonstrating the superiority of human over animal, lion taming served a purpose similar to animal fights of previous centuries. [215] The ultimate proof of a tamer's dominance and control over a lion is demonstrated by the placing of the tamer's head in the lion's mouth. The now-iconic lion tamer's chair was possibly first used by American Clyde Beatty (1903–1965). [216]

Hunting and games

Lion hunting has occurred since ancient times and was often a royal pastime; intended to demonstrate the power of the king over nature. The earliest surviving record of lion hunting is an ancient Egyptian inscription dated circa 1380 BC that mentions Pharaoh Amenhotep III killing 102 lions "with his own arrows" during the first ten years of his rule. The Assyrians would release captive lions in a reserved space for the king to hunt; this event would be watched by spectators as the king and his men, on horseback or chariots, killed the lions with arrows and spears. Lions were also hunted during the Mughal Empire, where Emperor Jahangir is said to have excelled at it. [217] In Ancient Rome, lions were kept by emperors for hunts as well as gladiator fights and executions. [218]

The Maasai people have traditionally viewed the killing of lions as a rite of passage. Historically, lions were hunted by individuals, however, due to reduced lion populations, elders discourage solo lion hunts. [219] During the European colonisation of Africa in the 19th century, the hunting of lions was encouraged because they were considered as vermin and lion hides fetched £1 each. [220] The widely reproduced imagery of the heroic hunter chasing lions would dominate a large part of the century. [221] Trophy hunting of lions in recent years has been met with controversy; notably with the killing of Cecil the lion in mid-2015. [222]

Man-eating

Lions do not usually hunt humans but some (usually males) seem to seek them out. One well-publicised case is the Tsavo maneaters; in 1898, 28 officially recorded railway workers building the Kenya-Uganda Railway were taken by lions over nine months during the construction of a bridge in Kenya. [223] The hunter who killed the lions wrote a book detailing the animals' predatory behaviour; they were larger than normal and lacked manes, and one seemed to suffer from tooth decay. The infirmity theory, including tooth decay, is not favoured by all researchers; an analysis of teeth and jaws of man-eating lions in museum collections suggests that while tooth decay may explain some incidents, prey depletion in human-dominated areas is a more likely cause of lion predation on humans. [224] Sick or injured animals may be more prone to man-eating but the behaviour is not unusual, nor necessarily aberrant. [225]

Lions' proclivity for man-eating has been systematically examined. American and Tanzanian scientists report that man-eating behaviour in rural areas of Tanzania increased greatly from 1990 to 2005. At least 563 villagers were attacked and many eaten over this period. The incidents occurred near Selous National Park in Rufiji District and in Lindi Province near the Mozambican border. While the expansion of villages into bush country is one concern, the authors argue conservation policy must mitigate the danger because in this case, conservation contributes directly to human deaths. Cases in Lindi in which lions seize humans from the centres of substantial villages have been documented. [226] Another study of 1,000 people attacked by lions in southern Tanzania between 1988 and 2009 found that the weeks following the full moon, when there was less moonlight, were a strong indicator of increased night-time attacks on people. [227]

According to Robert R. Frump, Mozambican refugees regularly crossing Kruger National Park, South Africa, at night are attacked and eaten by lions; park officials have said man-eating is a problem there. Frump said thousands may have been killed in the decades after apartheid sealed the park and forced refugees to cross the park at night. For nearly a century before the border was sealed, Mozambicans had regularly crossed the park in daytime with little harm. [228]

The lion is one of the most widely recognised animal symbols in human culture. It has been extensively depicted in sculptures and paintings, on national flags, and in contemporary films and literature. [47] It appeared as a symbol for strength and nobility in cultures across Europe, Asia and Africa, despite incidents of attacks on people. The lion has been depicted as "king of the jungle" and "king of beasts", and thus became a popular symbol for royalty and stateliness. [230] The lion is also used as a symbol of sporting teams. [231] [232] [233]

Depictions of lions are known from the Upper Paleolithic period. Carvings and paintings of lions discovered in the Lascaux and Chauvet Caves in France have been dated to 15,000 to 17,000 years old. [234] [229] A lioness-headed ivory carving found in Vogelherd cave in the Swabian Alb, southwest Germany, is dubbed Löwenmensch (lion-human) in German. The sculpture has been dated to least 32,000 years old—and as early as 40,000 years ago [235] —and originated from the Aurignacian culture. [29]

Sub-Saharan Africa

In sub-Saharan Africa, the lion has been a common character in stories, proverbs and dances, but rarely featured in visual arts. [236] In some cultures, the lion symbolises power and royalty. [237] In Swahili language, the lion is known as simba which also means "aggressive", "king" and "strong". [55] Some rulers had the word "lion" in their nickname. Sundiata Keita of the Mali Empire was called "Lion of Mali". [238] The founder of the Waalo kingdom is said to have been raised by lions and returned to his people part-lion to unite them using the knowledge he learned from the lions. [237]

In parts of West Africa, lions symbolised the top class of their social hierarchies. [237] In more heavily forested areas where lions were rare, the leopard represented the top of the hierarchy. [236] In parts of West and East Africa, the lion is associated with healing and is regarded as the link between seers and the supernatural. In other East African traditions, the lion is the symbol of laziness. [237] In much of African folklore, the lion is portrayed as having low intelligence and is easily tricked by other animals. [238]

Near East

The ancient Egyptians portrayed several of their war deities as lionesses, which they revered as fierce hunters. Egyptian deities associated with lions include Sekhmet, Bast, Mafdet, Menhit, Pakhet and Tefnut. [230] These deities were often connected with the sun god Ra and his fierce heat, and their dangerous power was invoked to guard people or sacred places. The sphinx, a figure with a lion's body and the head of a human or other creature, represented a pharaoh or deity who had taken on this protective role. [239]

The lion was a prominent symbol in ancient Mesopotamia from Sumer up to Assyrian and Babylonian times, where it was strongly associated with kingship. [240] Lions were among the major symbols of the goddess Inanna/Ishtar. [241] [242] The Lion of Babylon was the foremost symbol of the Babylonian Empire. [243] The Lion Hunt of Ashurbanipal is a famous sequence of Assyrian palace reliefs from c.640 BC, now in the British Museum. [244] The Lion of Judah is the biblical emblem of the tribe of Judah and the later Kingdom of Judah. [245] Lions are frequently mentioned in the Bible; notably in the Book of Daniel in which the eponymous hero refuses to worship King Darius and is forced to sleep in the lions' den where he is miraculously unharmed ( Dan 6 ). In the Book of Judges, Samson kills a lion as he travels to visit a Philistine woman.( Judg 14 ). [246]

Far East

Indo-Persian chroniclers regarded the lion as keeper of order in the realm of animals. The Sanskrit word mrigendra signifies a lion as king of animals in general or deer in particular. [247] Narasimha, the man-lion, is one of ten avatars of the Hindu god Vishnu. [248] Singh is an ancient Indian vedic name meaning "lion", dating back over 2,000 years. It was originally used only by Rajputs, a Hindu Kshatriya or military caste but is used by millions of Hindu Rajputs and more than twenty million Sikhs today. [249] The Lion Capital of Ashoka, erected by Emperor Ashoka in the 3rd century CE, depicts four lions standing back to back. It was made the National Emblem of India in 1950. [250] The lion is also symbolic for the Sinhalese people; [251] the term derived from the Sanskrit Sinhala, meaning "of lions" [252] while a sword-wielding lion is the central figure on the national flag of Sri Lanka. [253]

The lion is a common motif in Chinese art; it was first used in art during the late Spring and Autumn period (fifth or sixth century BC) and became more popular during the Han Dynasty (206 BC AD 220) when imperial guardian lions started to be placed in front of imperial palaces for protection. Because lions have never been native to China, early depictions were somewhat unrealistic; after the introduction of Buddhist art to China in the Tang Dynasty after the sixth century AD, lions were usually depicted wingless with shorter, thicker bodies and curly manes. [254] The lion dance is a traditional dance in Chinese culture in which performers in lion costumes mimic a lion's movements, often with musical accompaniment from cymbals, drums and gongs. They are performed at Chinese New Year, the August Moon Festival and other celebratory occasions for good luck. [255]

Western world

Lion-headed figures and amulets were excavated in tombs in the Greek islands of Crete, Euboea, Rhodes, Paros and Chios. They are associated with the Egyptian deity Sekhmet and date to the early Iron Age between the 9th and 6th centuries BC. [256] The lion is featured in several of Aesop's fables, notably The Lion and the Mouse. [257] The Nemean lion was symbolic in ancient Greece and Rome, represented as the constellation and zodiac sign Leo, and described in mythology, where it was killed and worn by the hero Heracles, [258] symbolising victory over death. [259] Lancelot and Gawain were also heroes slaying lions in the Middle Ages. In some medieval stories, lions were portrayed as allies and companions. [260] "Lion" was the nickname of several medieval warrior-rulers with a reputation for bravery, such as Richard the Lionheart. [230]

Lions continue to appear in modern literature as characters including the messianic Aslan in the 1950 novel The Lion, the Witch and the Wardrobe and The Chronicles of Narnia series by C. S. Lewis, [261] and the comedic Cowardly Lion in L. Frank Baum's 1900 The Wonderful Wizard of Oz . [262] Lion symbolism was used from the advent of cinema; one of the most iconic and widely recognised lions is Leo, which has been the mascot for Metro-Goldwyn-Mayer studios since the 1920s. [263] The 1966 film Born Free features Elsa the lioness and is based on the 1960 non-fiction book with the same title. [264] The lion's role as king of the beasts has been used in the 1994 Disney animated feature film The Lion King . [265]

Lions are frequently depicted on coats of arms, like on the coat of arms of Finland, [266] either as a device on shields or as supporters, but the lioness is used much less frequently. [267] The heraldic lion is particularly common in British arms. It is traditionally depicted in a great variety of attitudes, although within French heraldry only lions rampant are considered to be lions; feline figures in any other position are instead referred to as leopards. [268]

Jaguar A large cat native to the Americas

The jaguar is a large felid species and the only extant member of the genus Panthera native to the Americas. The jaguar's present range extends from the southwestern United States and Mexico in North America, across much of Central America, and south to Paraguay and northern Argentina in South America. Though there are single cats now living within Arizona, the species has largely been extirpated from the United States since the early 20th century. It is listed as Near Threatened on the IUCN Red List; and its numbers are declining. Threats include loss and fragmentation of habitat.

Tiger Largest species of the cat family

The tiger is the largest extant cat species and a member of the genus Panthera. It is most recognisable for its dark vertical stripes on orange-brown fur with a lighter underside. It is an apex predator, primarily preying on ungulates such as deer and wild boar. It is territorial and generally a solitary but social predator, requiring large contiguous areas of habitat, which support its requirements for prey and rearing of its offspring. Tiger cubs stay with their mother for about two years, before they become independent and leave their mother's home range to establish their own.

Leopard A large cat native to Africa and Eurasia

The leopard is one of the five extant species in the genus Panthera, a member of the Felidae. It occurs in a wide range in sub-Saharan Africa, in small parts of Western and Central Asia, on the Indian subcontinent to Southeast and East Asia. It is listed as Vulnerable on the IUCN Red List because leopard populations are threatened by habitat loss and fragmentation, and are declining in large parts of the global range. In Hong Kong, Singapore, Kuwait, Syria, Libya, Tunisia and most likely in Morocco, leopard populations have already been extirpated. Contemporary records suggest that the leopard occurs in only 25% of its historical global range.

Cheetah Large feline of the genus Acinonyx

The cheetah is a large cat native to Africa and central Iran. It is the fastest land animal, capable of running at 80 to 128 km/h, and as such has several adaptations for speed, including a light build, long thin legs and a long tail. Cheetahs typically reach 67–94 cm (26–37 in) at the shoulder, and the head-and-body length is between 1.1 and 1.5 m. Adults typically weigh between 20 and 65 kg. Its head is small, rounded, and has a short snout and black tear-like facial streaks. The coat is typically tawny to creamy white or pale buff and is mostly covered with evenly spaced, solid black spots. Four subspecies are recognised.

Bengal tiger Tiger population in Indian subcontinent

The Bengal tiger is a tiger from a specific population of the Panthera tigris tigris subspecies that is native to the Indian subcontinent. It is threatened by poaching, loss, and fragmentation of habitat, and was estimated at comprising fewer than 2,500 wild individuals by 2011. None of the Tiger Conservation Landscapes within its range is considered large enough to support an effective population of more than 250 adult individuals. India's tiger population was estimated at 1,706–1,909 individuals in 2010. By 2018, the population had increased to an estimated 2,603–3,346 individuals. Around 300–500 tigers are estimated in Bangladesh, 220–274 tigers in Nepal and 103 tigers in Bhutan.

Spotted hyena Species of hyena

The spotted hyena, also known as the laughing hyena, is a hyena species, currently classed as the sole extant member of the genus Crocuta, native to sub-Saharan Africa. It is listed as being of least concern by the IUCN on account of its widespread range and large numbers estimated between 27,000 and 47,000 individuals. The species is, however, experiencing declines outside of protected areas due to habitat loss and poaching. The species may have originated in Asia, and once ranged throughout Europe for at least one million years until the end of the Late Pleistocene. The spotted hyena is the largest known member of the Hyaenidae, and is further physically distinguished from other species by its vaguely bear-like build, its rounded ears, its less prominent mane, its spotted pelt, its more dual purposed dentition, its fewer nipples and the presence of a pseudo-penis in the female. It is the only mammalian species to lack an external vaginal opening.

Barbary lion Extinct lion population in North Africa

The Barbary lion was a Panthera leo leo population in North Africa that is regionally extinct today. This population occurred in Barbary Coastal regions of Maghreb from the Atlas Mountains to Egypt and was eradicated following the spreading of firearms and bounties for shooting lions. A comprehensive review of hunting and sighting records revealed that small groups of lions may have survived in Algeria until the early 1960s, and in Morocco until the mid-1960s.

<i>Panthera spelaea</i> Extinct cave lion species

Panthera spelaea, also known as the "Eurasian cave lion", "European cave lion", or "steppe lion", is an extinct Panthera species that evolved in Europe probably after the third Cromerian interglacial stage, less than 600,000 years ago. Phylogenetic analysis of fossil bone samples revealed that it was highly distinct and genetically isolated from the modern lion occurring in Africa and Asia. Analysis of morphological differences and mitochondrial data support the taxonomic recognition of Panthera spelaea as a distinct species that diverged from the lion about 1.9 million years ago. Nuclear genomic evidence suggests a more recent split approximately 500,000 years ago, with no subsequent interbreeding with the ancestors of the modern lion. The oldest known bone fragments were excavated in Yakutia and radiocarbon dated at least 62,400 years old. It became extinct about 13,000 years ago.

Cape lion An extinct lion population in South Africa

The Cape lion was a Panthera leo melanochaita population in South Africa's Natal and Cape Provinces that was extirpated in the mid-19th century. The type specimen originated at the Cape of Good Hope and was described in 1842.

Asiatic lion Lion population in India

The Asiatic lion is a Panthera leo leo population in India. Its current range is restricted to the Gir National Park and environs in the Indian state of Gujarat. Historically, it inhabited much of Western Asia and the Middle East up to northern India. On the IUCN Red List, it is listed under its former scientific name Panthera leo persica as Endangered because of its small population size and area of occupancy.

<i>Panthera leo leo</i> Lion subspecies

Panthera leo leo is a lion subspecies, which is present in West Africa, northern Central Africa and India. In West and Central Africa it is restricted to fragmented and isolated populations with a declining trajectory. It has been referred to as the 'Northern lion'.

A Panthera hybrid is a crossbreed between any of four species—tiger, lion, jaguar and leopard—in captivity. Most hybrids would not be perpetuated in the wild as males are usually infertile. Mitochondrial genome research revealed that wild hybrids were also present in ancient times. The mitochondrial genomes of snow leopard and lion were more similar to each other than to other Panthera species, indicating that at some point in their history, the female progeny of male ancestors of modern snow leopards and female ancestors of modern lions interbred with male ancestors of modern snow leopards.

African leopard Leopard subspecies

The African leopard is the nominate subspecies of the leopard, native to many countries in Africa. It is widely distributed in most of sub-Saharan Africa, but the historical range has been fragmented in the course of habitat conversion. Leopards have been recorded in North Africa as well.

Asiatic cheetah The only living cheetah subspecies outside of Africa

The Asiatic cheetah, also known as Iranian cheetah, is a Critically Endangered cheetah subspecies surviving today only in Iran. It once occurred from the Arabian Peninsula and the Near East to the Caspian region, Kyzylkum Desert and India, but has been extirpated there during the 20th century.

Indian leopard Leopard subspecies

The Indian leopard is a leopard subspecies widely distributed on the Indian subcontinent. The species Panthera pardus is listed as Vulnerable on the IUCN Red List because populations have declined following habitat loss and fragmentation, poaching for the illegal trade of skins and body parts, and persecution due to conflict situations.

<i>Panthera leo melanochaita</i> Lion subspecies

Panthera leo melanochaita is a lion subspecies in Southern and East Africa. In this part of Africa, lion populations are regionally extinct in Lesotho, Djibouti and Eritrea, and threatened by loss of habitat and prey base, killing by local people in retaliation for loss of livestock, and in several countries also by trophy hunting. Since the turn of the 21st century, lion populations in intensively managed protected areas in Botswana, Namibia, South Africa and Zimbabwe have increased, but declined in East African range countries. In 2005, a Lion Conservation Strategy was developed for East and Southern Africa.

Asiatic Lion Reintroduction Project initiative of the Indian Government

The Asiatic Lion Reintroduction Project is an initiative of the Indian Government to provide safeguards to the Asiatic lion from extinction in the wild by means of reintroduction. The last wild population of the Asiatic lion is found in the region of Gir Forest National Park, in the state of Gujarat. The single population faces the threats of epidemics, natural disasters and other anthropogenic factors. The project aims to establish a second independent population of Asiatic lions at the Kuno Wildlife Sanctuary in the Indian state of Madhya Pradesh. However, the proposed translocation has been bitterly contested by the state government.

Tiger versus lion Historical comparison of tiger and lion

Historically, a comparison of the tiger versus the lion has been a popular topic of discussion by hunters, naturalists, artists, and poets, and continues to inspire the popular imagination. In the past, lions and tigers reportedly competed in the wilderness, where their ranges overlapped in Eurasia. The most common reported circumstance of their meeting is in captivity, either deliberately or accidentally.

East African cheetah subspecies of cheetah

The East African cheetah, is a cheetah population in East Africa. It lives in grasslands and savannas of Tanzania, Kenya, Uganda and Somalia. The cheetah inhabits mainly the Serengeti ecosystem, including Maasai Mara, and the Tsavo landscape.

Maneless lion Type of male lions that can be without manes or having weak manes

The term "maneless lion" or "scanty manes" often refers to a male lion without a mane, or with a weak one. The purpose of the mane is thought to protect the lion in territorial fights. Although lions are known for their mane, not all males have one.
