The Southern lion (Panthera leo melanochaita), also referred to as the East-Southern African lion, is a subspecies of the lion in Southern and East Africa. In this part of Africa, lion populations are regionally extinct in Lesotho, Djibouti and Eritrea. 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. They are 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. The type specimen for P. l. melanochaita was a black-maned lion from the Cape of Good Hope, known as the Cape lion, and consequently, the scientific name was initially meant for it. The lion population in this part of South Africa is extinct.

Taxonomic history
Charles Hamilton Smith described the type specimen for Panthera leo melanochaita in 1842 using the scientific name Felis (Leo) melanochaitus. It was referred to as the "Southern relative" of the North African lion. In the 19th and 20th centuries, several naturalists described specimens from Southern and East Africa and proposed subspecies, including: Dispute over the validity of these purported subspecies continued among naturalists and curators of natural history museums until the early 21st century. In the 20th century, some authors supported the view of the Cape lion being a distinct subspecies. In 1939, the American zoologist Allen also recognized F. l. bleyenberghi, F. l. krugeri and F. l. vernayi as valid subspecies in Southern Africa, and F. l. hollisteri, F. l. nyanzae and F. l. massaica as valid subspecies in East Africa. Pocock subordinated lions to the genus Panthera in 1930, when he wrote about Asiatic lions. Ellerman and Morrison-Scott recognized only two lion subspecies in the Palearctic realm, namely the African P. l. leo and the Asiatic P. l. persica. Various authors recognized between seven and 10 African lion subspecies. Others followed the classification proposed by Ellerman and Morrison-Scott, recognizing two subspecies including one in Africa. In the 1970s, the scientific name P. l. vernayi was considered synonymous with P. l. krugeri. In 1975, Vratislav Mazák hypothesized that the Cape lion evolved geographically isolated from other populations by the Great Escarpment. In the early 21st century, Mazák's hypothesis about a geographically isolated evolution of the Cape lion was challenged. Genetic exchanges between populations in the Cape, Kalahari and Transvaal Province regions and farther east are considered having been possible through a corridor between the Great Escarpment and the Indian ocean. In 2005, the authors of Mammal Species of the World recognized P. l. bleyenberghi and P. l. krugeri, P. l. vernayi P. l. massaica, P. l. hollisteri and P. l. nyanzae as valid taxa. In 2016, IUCN Red List assessors subsumed all African lion populations to P. l. leo. In 2017, the Cat Classification Task Force of the Cat Specialist Group reduced the number of valid lion subspecies in Southern and Southeast Africa to one, namely P. l. melanochaita.

Genetic research
Since the beginning of the 21st century, several phylogenetic studies were conducted to aid clarifying the taxonomic status of lion samples kept in museums and collected in the wild. Scientists analysed between 32 and 197 lion samples from up to 22 countries. Based on the results of a genetic analyses, it appears that the species comprises two main evolutionary groups, one in Southern and East Africa, and the other in the northern and eastern parts of its historical range; these groups diverged about 50,000 years ago. It was assumed that tropical rainforest and the East African Rift constituted major barriers between the two groups. Based on this assessment, the species comprises two recognised subspecies: The two groups were in contact in Ethiopia or northern parts of East Africa. A phylogeographic analysis of 194 lion sequences from 22 countries indicated that East African and Southern African lions form a clade that diverged about 186,000–128,000 years ago from the clade formed by North, West and certain Central African lions. In 9 of 19 lion samples from Ethiopia, haplotypes of the Central African lion group were found, indicating that the Great Rift Valley was not a complete barrier to gene flow; southeastern Ethiopia is considered a genetic admixture zone between Central and East African lions. Since 2005, several phylogeographic studies were conducted to aid clarifying the taxonomic status of lion samples kept in museums and collected in the wild. Results of a DNA analysis using 26 lion samples from Southern and East Africa indicate that genetic variation between them is low and that two major clades exist: one in southwestern Africa and one in the region from Uganda and Kenya to KwaZulu-Natal. Five lion samples from Kenya's Tsavo East National Park showed identical haplotypes as three lion samples from the Transvaal region in South Africa. Results of phylogeographic studies support the notion of lions in Southern Africa being genetically close, but distinct from populations in West and North Africa and Asia. Based on the analysis of samples from 357 lions from 10 countries, it is thought that lions migrated from Southern Africa to East Africa during the Pleistocene and Holocene eras. A phenotypic and DNA analysis was conducted using samples from 15 captive lions in the Addis Ababa Zoo and from six wild lion populations. Results showed that the captive lions were genetically similar to wild lions from Cameroon and Chad, but with little signs of inbreeding. Lions samples from Gabon's Batéké Plateau National Park and Odzala-Kokoua National Park in Republic of the Congo were found to be related to the Southern lion clade.

Characteristics
The lion's fur varies in colour from light buff to dark brown. It has rounded ears and a black tail tuft. Average head-to-body length of male lions is 2.47 - 2.84 m with a weight of 148.2 - 190.9 kg. The largest East African lion measured 3.33 m. Females are smaller and less heavy. The Cape lion had a black mane extending beyond the shoulders and under the belly. Yet, black-maned lions also occur in the Kalahari and eastern Okavango Delta alongside those with a normal tawny colour. Until the late 20th century, mane colour and size was thought to be a distinct subspecific characteristic. In 2002, research in Serengeti National Park revealed that mane darkens with age; its colour and size are influenced by environmental factors like temperature and climate, but also by individual testosterone production, sexual maturity and genetic precondition. Mane length apparently signals fighting success in male–male relationships. An exceptionally heavy male near Mount Kenya weighed 272 kg. Male lions killed in East Africa were less heavy than lions killed by hunters in Southern Africa. The captive male lions at Addis Ababa Zoo have darker manes and smaller bodies than those of wild populations. White lions have occasionally been encountered in and around Kruger National Park and the adjacent Timbavati Private Game Reserve in South Africa. Their whitish fur is a rare morph caused by a double recessive allele.

Manes
In the 19th and 20th centuries, lion type specimen were described on the basis of mane size and colour. Male East African lions are known for a great range of mane types. Mane development is related to age: older males have more extensive manes than younger ones; manes continue to grow up to the age of four to five years, long after lions have become sexually mature. Males living in the highlands above 800 m elevation develop heavier manes than lions in the more humid and warmer lowlands of eastern and northern Kenya. The latter have thinner manes, or are even completely maneless. Hence, lion manes reflect ambient temperature. The mane colour is also influenced by nutrition and testosterone. Its length is an indicator for age and fighting ability of the lion. A male lion specimen from Somalia had a short mane. Male lions from the Ethiopian highlands had dark and heavy manes with black tips that extended over the whole throat and chest to the forelegs and behind the shoulders. A few lions observed in the environs of Mount Kilimanjaro had tawny to sandy coloured manes as well. Two male lions observed in the border region between Kenya and Tanzania had moderate tufts of hair on the knee joint, and their manes appeared brushed backwards. They were less cobby with longer legs and less curved backs than lions from other African range countries. Mane colour of males in Kenya vary between tawny, isabelline and light reddish yellow. Tsavo male lions generally do not have a mane, though colouration and thickness vary. There are several hypotheses as to the reasons. One is that mane development is closely tied to climate because its presence significantly reduces heat loss. An alternative explanation is that manelessness is an adaptation to the thorny vegetation of the Tsavo area in which a mane might hinder hunting. Tsavo males may have heightened levels of testosterone, which could also explain their reputation for aggression. The weak or absent mane of Tsavo lions is a feature, which was characteristic also for the extinct lions of ancient Egypt and Nubia. Adult lion males in Egyptian art are usually depicted without a mane, but with a ruff around the neck.

White lion
The white lion is a rare morph with a genetic condition called leucism, which is caused by a double recessive allele. It has normal pigmentation in eyes and skin. White individuals have been occasionally encountered only 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 different prides between 2007 and 2015. White lions are selected for breeding in captivity. Reportedly, they have been bred in camps in South Africa for use as trophies to be killed during canned hunts.

Records
In 1936, a man-eating lion shot by Lennox Anderson, outside Hectorspruit in Eastern Transvaal weighed about 313 kg and was considered to be the heaviest wild lion. The longest wild lion reportedly was a male shot near Mucusso in southern Angola in 1973.

Distribution and habitat
The southern lion was originally found from Ethiopia and Uganda in the north to the Cape of Good Hope in the south. Supported by genetic research, the border between the Southern and Northern subspecies runs through Ethiopia. Southeastern Ethiopia is considered a genetic admixture zone between the two groups. Within the Southern lion, genetic research identified three clades. These are the Northeastern, East-Southern and Southwestern subclade. In East and Southern Africa, the population of lions declined in: Contemporary lion distribution and habitat quality in East and Southern Africa was assessed in 2005, and Lion Conservation Units (LCU) mapped. Between 2002 and 2012, educated guesses for size of populations in these LCUs ranged from 33,967 to 32,000 individuals. The LCUs Ruaha-Rungwa, Serengeti-Mara, Tsavo-Mkomazi and Selous in East Africa, as well as Luangwa, Kgalagadi, Okavango-Hwange, Mid-Zambezi, Niassa and Greater Limpopo in Southern Africa are currently considered as lion strongholds. These LCUs host more than 500 individuals each, and the population trend is stable there.
 * Somalia since the early 20th century. Intensive poaching since the 1980s and civil unrest posed a threat to lion persistence.
 * Uganda to near extinction in the 20th century.
 * Kenya in the 1990s due to poisoning of lions and poaching of lion prey species.
 * Rwanda and Tanzania due to killing of lions during the Rwandan Civil War and ensuing refugee crisis in the 1990s.
 * Malawi and Zambia due to illegal hunting of prey species in protected areas.
 * Botswana due to intensive hunting and conversion of natural habitats for settlements since the early 19th century.
 * Namibia due to massive killing of lions by farmers since at least the 1970s.
 * South Africa since the early 19th century in the Natal and Cape Provinces south of the Orange River, where the Cape lion population was eradicated by 1860. A few decades later, lions in the Highveld north of the Orange River were also eradicated. In the Transvaal, lions occurred historically in the Highveld as well, but were restricted to eastern Transvaal's Bushveld by the 1970s.

Admixture zone to the Northern subspecies
One of the largest lion populations in Ethiopia is found in Gambella. According to genetic research, this population, which is contigous with populations in Sudan, does not belong to the Southern subspecies but to the Northern lion. The same is probably true for the populations in northern Ethiopia, where, a group of lions was recorded in 2016 in Alatash National Park close to the international border with Sudan. Other parts of Ethiopia, which still have lions fall into the admixture zone. These are Omo and Bale Mountains National Parks, the ara around the Chew Bahir and Turkana lakes, and the Webi Shabeelle area. In 2009, a small group of less than 23 lions were estimated in Nechisar National Park located in the Great Rift Valley. This small protected area in the Ethiopian Highlands is encroached by local people and their livestock. Lions of northern Uganda have not been analysed genetically and might belong to the Northern subspecies. In northern Uganda, lions are present in Kidepo Valley and Murchison Falls National Parks.

Northeastern clade
The range of the Northeastern clade outside the admixture zone is confined to Somalia and northern and central Kenya. Already in the 1980s, the lion population in Somalia had greatly declined due to poaching and was restricted to woodlands in the southern part of the country. In northern Kenya, lions had been observed near Kavirondo, near Lake Manyara and in the Tanga Region in the late 19th century. By the 21st century, lion populations in northern Kenya have been fragmented.

Southern / Eastern clade
This is the clade with the largest remaining populations. The range of this clade extends from southern Kenya, southern Uganda and the Virunga area in the Democratic Republic of the Congo southward to the Cape of Good Hope, excluding only the western parts of Southern Africa. The following complexes are considered lion strongholds of the Southern/Eastern clade: Lions in Queen Elizabeth National Park, which form a contiguous population with lions in Virunga National Park in the northeastern part of the Democratic Republic of the Congo, do belong to the Southern Eastern clade. In 2010, the lion population in Uganda was estimated at 408 ± 46 individuals in three protected areas including Queen Elizabeth, Murchison Falls and Kidepo Valley National Parks. Other protected areas in the country probably host less than 10 lions. As of 2006, there were an estimated 675 lions in the Tsavo area, out of the 2,000 total in Kenya. Between 2004 and 2013, lion guardians around Amboseli National Park identified 65 lions in an area of 3684 km2. A small population is present in Rwanda's Akagera National Park, estimated at 35 individuals at most in 2004. The lion population in South Africa's former Natal and Cape Provinces is locally extinct since the mid 19th century. The last lions south of the Orange River were sighted between 1850 and 1858. Between 2000 and 2004, 34 lions were reintroduced to eight protected areas in the Eastern Cape Province, including Addo Elephant National Park.

Limpopo admixture zone
The area of the Kruger National Park, which is part of the Great Limpopo Transfrontier Park, is an admixture zone between the Southern-Eastern and the Southwestern clade. This area is a lion stronghold with about 2,300 lions.

Southwestern clade
The only stronghold of the Southwestern clade is in the western parts of the Kavango–Zambezi Transfrontier Conservation Area, including Okavango Delta and Hwange National Park Another important reserve for this clade is the Etosha National Park. Lions are considered regionally extinct in the southwestern part of the Democratic Republic of the Congo. In Gabon, the presence of lions in Batéké Plateau National Park was doubtful in 2010. In 2015, a camera trap recorded a single male lion in this national park. Continued camera trapping in the area for more than one year recorded the same lion repeatedly. Its hair samples were collected for phylogenetic analysis and compared with tissue samples of lions from Gabon and Republic of the Congo that were killed in the 20th century. Results indicate that this individual is closely related to the ancestral lion population of the area, and that its DNA shows a typical Southern lion haplotype. It is considered possible that this lion dispersed to the area from Namibia or Botswana. In the Republic of the Congo, the Odzala-Kokoua National Park was considered a lion stronghold in the 1990s. By 2014, no lions were recorded in the protected area, so that now, the species is considered locally extinct in the country.

Behaviour and ecology
The lion is a social cat, living in groups of related individuals with their offspring. Such a family group is called a 'pride'. 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 also been observed. Male lion groups are called a 'coalition'. Membership only changes with the births and deaths of female lions. Male cubs are excluded from their maternal pride when they reach maturity at around 2–3 years of age. The sole known exception of this pattern is the Tsavo lion pride, which always has just one adult male. Male lions spend years in a nomadic phase before gaining residence in a pride. In 1966, a program was started to monitor lions in Serengeti National Park. Between 1966 and 1972, two observed prides had between seven and ten females each. On average, females had litters once in 23 months. Two or three cubs comprised the litters, and only twelve managed to grow to the age of two, out of 87 cubs born until 1970. Cubs died due to starvation in months Factors that contributed to the deaths of cubs were starvation, when large prey was not available, or when new males took over the prides. Between 1974 and 2015, prides were monitored again, and until 2012, 471 coalitions comprising 796 male lions entered a study area of 2000 km2. Of these, 35 coalitions included male lions that were born in this place but had left and returned after being absent for about two years. Nomadic coalitions gain residency at between 3.5 and 7.3 years of age. Results of a 10-year long survey on 50 radio-collared lions in the Kavango–Zambezi Transfrontier Conservation Area show that adult lions preferred grassland and shrubland habitat, but avoided woodlands and areas with high human density; by contrast, subadult dispersing male lions avoided grasslands and shrublands, but moved in human-dominated areas to a larger extent. Hence, dispersing lions are more vulnerable to coming into conflict with humans than adult lions. Lions usually hunt in groups and prey foremost on ungulates such as wildebeest, zebra, African buffalo, gemsbok and giraffe. In the Serengeti National Park, lions were observed to also scavenge on carrion when the opportunity arises. They scavenged animals that were killed by other predators, or died from natural causes. They kept a constant lookout for circling vultures, apparently being aware that vultures indicate a dead animal. Sympatric predators include the leopard, cheetah, hyena and African wild dog. Lions predominantly hunt large ungulates like zebra, warthog, blue wildebeest, impala, gemsbok, Thomson's gazelle, kob, waterbuck, kudu, giraffe and Cape buffalo. Their prey is usually in the range of 40.0 to 270.0 kg. Predation on adult African bush elephants has been observed in Chobe National Park, Botswana. Sympatric predators include the leopard, cheetah, hyena and African wild dog. Lions in Botswana's Okavango Delta have learned to swim in the delta's swamps. They hunt large prey like buffalo, and occasionally also African elephants when smaller prey is scarce.

Attacks on humans

 * In the 19th century, north of Bechuanaland, a lion non-fatally attacked David Livingstone, who was defending a sheep in a village.
 * Two Tsavo males have been known as man-eaters, after an incident during the building of the Uganda Railway in the 1890s. Their skulls and skins are part of the zoological collection of the Field Museum of Natural History in Chicago, the United States of America. The total number of people killed is unclear, but allegedly 135 people fell victim to these lions in less than a year before Colonel John Patterson killed them.
 * The "Njombe lions" were a pride of lions in Njombe, in what was then Tanganyika, which for over three generations are thought to have preyed on 1,500 to 2,000 people. They were eventually dispatched by George Rushby.
 * In February 2018, a suspected poacher was killed and eaten by lions near Kruger National Park.
 * Towards the end of the same month, conservationist Kevin Richardson took three lions for a walk at Dinokeng Game Reserve, near Pretoria in South Africa. A lioness then pursued an impala for at least 2 km, before unexpectedly killing a 22-year-old woman near her car.
 * In July 2018, a "loud commotion" coming from lions was heard by an anti-poaching dog in Sibuya Game Reserve near Kenton-on-Sea, South Africa. The next day, human remains were found in the lion enclosure. They were suspected to have been rhino-poachers, as they had equipment such as a high-powered rifle and wire cutters.

Threats
In Africa, lions are threatened by pre-emptive killing or in retaliation for preying on livestock. Prey base depletion, loss and conversion of habitat have led to a number of subpopulations becoming small and isolated. Trophy hunting has contributed to population declines in Botswana, Namibia, Zimbabwe and Zambia. Although lions and their prey are officially protected in Tsavo National Parks, they are regularly killed by local people, with over 100 known lion killings between 2001 and 2006. Between 2008 and 2013, bones and body parts from at least 2621 individual lions were exported from South Africa to Southeast Asia, and another 3437 lion skeletons between 2014 and 2016. Lion bones are used to replace tiger bones in traditional Asian medicines. Private game ranches in South Africa also breed lions for the canned hunting industry. In 2014, seven lions in Ikona Wildlife Management Area were reportedly poisoned by a herdsman for attacking his cattle. In February 2018, the carcasses of two male and four female lions were found dead in Ruaha National Park, and were suspected to have died of poisoning. In 2015 and 2017, two male lions, Cecil and his son Xanda, were killed by trophy hunters in Zimbabwe's Hwange National Park. In Zambia's Kafue National Park, uncontrolled bushfires and hunting of lions and prey species makes it difficult for the lion population to recover. Cub mortality in particular is high.

Conservation
African lions are included in CITES Appendix II. Today, lion populations are stable only in large protected area complexes. IUCN regional offices and many wildlife conservation organisations cooperated to develop a Lion Conservation Strategy for Eastern and Southern Africa in 2006. The strategy envisages to maintain sufficient habitat, ensure a sufficient wild prey base, make lion-human coexistence sustainable and reduce factors that lead to further fragmentation of populations. A significant incentive for local communities in a number of Southern African countries to support measures for conservation is that they generate significant revenue through wildlife tourism. In 2010, the small and isolated Kalahari population was estimated at 683 to 1,397 individuals in three protected areas, the Kgalagadi Transfrontier Park, the Kalahari Gemsbok and Gemsbok National Parks. More than 2000 lions exist in the well-protected Kruger National Park. In June 2015, seven lions were relocated from KwaZulu-Natal in South Africa to Akagera National Park in Rwanda.

In captivity
At the beginning of the 21st century, the Addis Ababa Zoo kept 16 adult lions. It is assumed that their ancestors, five males and two females, were caught in southwestern Ethiopia as part of a zoological collection for Emperor Haile Selassie I. In 2006, the registry of the International Species Information System (ISIS) showed 29 lions that were derived from animals captured in Angola and Zimbabwe. In addition, about 100 captive lions were registered as P. l. krugeri by ISIS, which derived from lions captured in South Africa. Interest in the Cape lion had led to attempts to conserve possible descendants in places like Tygerberg Zoo.

Regional names
Lion populations in Southern and East Africa were referred to by several regional names, including "Katanga lion", "Transvaal lion", "Kalahari lion", "Southeast African lion", and "Southwest African lion", "Masai lion", "Serengeti lion," "Tsavo lion" and "Uganda lion".

Cultural significance
The lion is featured as an animal symbol in East Africa. The name 'Simba' is a Swahili word for the lion, which also means 'aggressive', 'king' and 'strong'.
