Serval

The serval (Leptailurus serval) /ˈsɜːrvəl/ is a wild cat native to Africa. It is rare in North Africa and the Sahel, but widespread in sub-Saharan countries except rainforest regions. On the IUCN Red List it is listed as Least Concern.[1]

It is the sole member of the genus Leptailurus and was first described by German naturalist Johann von Schreber in 1776. Three subspecies are recognised. The serval is a slender, medium-sized cat that stands 54–62 cm (21–24 in) at the shoulder and weighs 9–18 kg (20–40 lb). It is characterised by a small head, large ears, a golden-yellow to buff coat spotted and striped with black, and a short, black-tipped tail. The serval has the longest legs of any cat relative to its body size.

Active in the day as well as at night, servals tend to be solitary with minimal social interaction. Both sexes establish highly overlapping home ranges of 10 to 32 km2 (4–12 sq mi), and mark them with feces and saliva. Servals are carnivores – they prey on rodents (particularly vlei rats), small birds, frogs, insects, and reptiles. The serval uses its sense of hearing to locate the prey; to kill small prey, it leaps over 2 m (6 ft 7 in) above the ground to land on the prey on its forefeet, and finally kills it with a bite on the neck or the head. Mating takes place at different times of the year in different parts of their range, but typically once or twice a year in an area. After a gestational period of two to three months, a litter of one to four is born. Weaning occurs at one month, and kittens begin hunting on their own at six months. The juveniles leave their mother at 12 months.

The serval prefers areas with cover such as reeds and tall grasses and proximity to water bodies, such as wetlands and savannahs. It occurs in protected areas across its range, and hunting of servals is either prohibited or regulated in several countries.

Taxonomy and phylogeny

The scientific name of the serval is Leptailurus serval. It is the sole member of the genus Leptailurus.[2] The species was first described by German naturalist Johann Christian Daniel von Schreber as Felis serval.[3] In 1858, Russian naturalist Nikolai Severtzov proposed the genus name Leptailurus.[4]

In the 19th and 20th centuries, some taxonomists inspected serval skins and identified two species on the basis of coat pattern: Felis serval (serval), with large, pronounced spots, and F. servalina or F. ornata (servaline cat), marked by freckle-sized dots.[5] F. servalina was first described in 1839 by Irish naturalist William Ogilby from Sierra Leone;[6] in 1867, British zoologist John Edward Gray described F. herschelii from an Indian skin, which was probably the same as the servaline cat.[7] In 1907, British zoologist Reginald Innes Pocock commented that the two forms should be considered independent species, but reverted from this in 1917.[8] Eventually, the two forms came to be recognised as the same species. Another form, F. himalayanus (Himalayan serval), was described from a skin procured from the Indian Himalayan Region; however, Scottish naturalist William Jardine noted in 1843 that no such specimen had been identified by him or his colleagues, and that it differed considerably from the common serval.[9] In 1944, Pocock identified three races of the serval from northern Africa.[10]

Three subspecies are recognised as valid since 2017:[11]

The phylogenetic relationships of the serval have remained in dispute; in 1997, palaeontologists M. C. McKenna and S. K. Bell classified Leptailurus as a subgenus of Felis, while others like O. R. P. Bininda-Edmonds (of the Technical University of Munich) have grouped it with Felis, Lynx and Caracal. Studies in the 2000s and the 2010s show that the serval, along with the caracal and the African golden cat, forms one of the eight lineages of Felidae. According to a 2006 genetic study, the Caracal lineage came into existence 8.5 million years ago, and the ancestor of this lineage arrived in Africa 8.5–5.6 mya.[12][13]

Etymology

The name Leptailurus may have been constructed from the medieval Greek λεπταλέος or λεπτός meaning "fine, delicate".[14] The name "serval" could have been derived from the Medieval Latin words Lupus cervalis ("deer-like wolf") or from its Portuguese equivalent lobo-cerval (referring to the Iberian lynx). The first recorded use of this name dates back to 1771.[15] Another name for the serval is "tierboskat",[16] Afrikaans for tiger-bush-cat.

Characteristics

The serval is a slender, medium-sized cat; it stands 54 to 62 cm (21–24 in) at the shoulder and weighs 8 to 18 kg (18–40 lb), but females tend to be lighter. The head-and-body length is typically between 67 and 100 cm (26–39 in).[17] Males tend to be sturdier than females.[8] Prominent characteristics include the small head, large ears, spotted and striped coat, long legs and a black-tipped tail that is around 30 cm (12 in) long.[16][18] The serval has the longest legs of any cat relative to its body size, largely due to the greatly elongated metatarsal bones in the feet.[5][19] The toes are elongated as well, and unusually mobile.[5]

The coat is basically golden-yellow to buff, and extensively marked with black spots and stripes.[8] The spots show great variation in size. Melanistic servals are also known.[5] Facial features include the brownish or greenish eyes, white whiskers on the snout and near the ears, ears as large as those of a domestic cat (but large relative to the size of the head) and black on the back with a white horizontal band in the middle, whitish chin, and spots and streaks on the cheeks and the forehead. Three to four black stripes run from the back of the head onto the shoulders, and then break into rows of spots. The white underbelly has dense and fluffy basal fur, and the soft guard hairs (the layer of fur protecting the basal fur) are 5–10 centimetres (2–4 in) long. Guard hairs are up to 3 centimetres (1 14 in) long on the neck, back and the flanks, and are merely 1 centimetre (12 in) long on the face.[18][20][8] The closely set ears are black on the back with a horizontal white band;[8] the ears can rotate up to 180 degrees independently of each other.[5] The serval has a good sense of smell, hearing and vision.[18]

The serval is similar to the sympatric caracal, but has a narrower spoor, a rounder skull, and lacks its prominent ear tufts. The African golden cat is darker, with different cranial features.[8] It resembles the cheetah in its build and coat pattern, though not in size.[18] The serval shares its adaptations to its marshy habitat with the jungle cat; both cats have large and sharp ears that help in locating the prey efficiently, and their long legs raise them above muddy ground and water.[22]

Distribution and habitat

In North Africa, the serval is known only from Morocco and has been reintroduced in Tunisia, but is feared to be extinct in Algeria. It inhabits semi-arid areas and cork oak forests close to the Mediterranean Sea, but avoids rainforests and arid areas. It occurs in the Sahel, and is widespread in Southern Africa. It prefers areas with cover, such as reeds and tall grasses, proximity to water bodies such as wetlands and savannahs. It inhabits grasslands, moorlands and bamboo thickets at high altitudes up to 3,800 m (12,500 ft) on Mount Kilimanjaro.[1][8] In 2014 and 2015, it was recorded in the floodplains and gallery forests of Benin’s Pendjari National Park by camera-traps.[23] In the East Sudanian Savanna, it was recorded in the transboundary DinderAlatash protected area complex during surveys between 2015 and 2018.[24]

In Zambia's Luambe National Park, the population density was recorded as 0.1/km2 (0.26/sq mi) in 2011.[25] In South Africa, the serval was recorded in Free State, eastern Northern Cape, and southern North West.[26] In Namibia, it is present in Khaudum and the Mudumu National Parks.[27]

Ecology and behaviour

Serval from back
Serval has eyespots on the backs of its ears.

The serval is active in the day as well as at night; activity might peak in early morning, around twilight and at midnight. Servals might be active for a longer time on cool or rainy days. During the hot midday, they rest or groom themselves in the shade of bushes and grasses. Servals remain cautious of their vicinity, though they may be less alert when no large carnivores or prey animals are around. Servals walk as much as 2 to 4 kilometres (1 14 to 2 12 miles) every night.[16][17] Servals will often use special trails to reach certain hunting areas. A solitary animal, there is little social interaction among servals except in the mating season, when pairs of opposite sexes may stay together. The only long-lasting bond appears to be of the mother and her cubs, which leave their mother only when they are a year old.[8]

Both males and females establish home ranges, and are most active only in certain regions ('core areas') within them. The area of these ranges can vary from 10 to 32 square kilometres (4 to 12 square miles); prey density, availability of cover and human interference could be significant factors in determining their size.[8][28] Home ranges might overlap extensively, but occupants show minimal interaction. Aggressive encounters are rare, as servals appear to mutually avoid one another rather than fight and defend their ranges. Agonistic behaviour involves vertical movement of the head (contrary to the horizontal movement observed in other cats), raising the hair and the tail, displaying the teeth and the white band on the ears, and yowling. Individuals mark their ranges and preferred paths by spraying urine on nearby vegetation, dropping scats along the way, and rubbing their mouth on grasses or the ground while releasing saliva. Servals tend to be sedentary, shifting only a few kilometres away even if they leave their range.[8][17]

The serval is vulnerable to hyaenas and wild dogs. It will seek cover to escape their view, and, if the predator is very close, immediately flee in long leaps, changing its direction frequently and with the tail raised.[17] The serval is an efficient, though not frequent, climber; an individual was observed to have climbed a tree to a height of more than 9 metres (30 feet) to escape dogs.[5] Like many cats, the serval is able to purr;[29] it also has a high-pitched chirp, and can hiss, cackle, growl, grunt and meow.[5]

Hunting and diet

The serval is a carnivore that preys on rodents, particularly vlei rats, small birds, frogs, insects and reptiles, and also feeds on grass that can facilitate digestion or act as an emetic. Up to 90% of the preyed animals weigh less than 200 grams (7 oz); occasionally it also hunts larger prey such as duikers, hares, flamingoes and young antelopes.[5] The percentage of rodents in the diet has been estimated at 80-97%.[28][30][31] Apart from vlei rats, other rodents recorded frequently in the diet include the African grass rat, African pygmy mouse and multimammate mice.[8]

Servals locate prey by their strong sense of hearing. To kill small prey, the serval will slowly stalk it, then pounce on it with the forefeet directed toward the chest, and finally land on it with its forelegs outstretched. The prey, receiving a blow from one or both of the serval's forepaws, is incapacitated, and the serval gives it a bite on the head or the neck and immediately swallows it. Snakes are dealt more blows and even bites, and may be consumed even as they are moving. Larger prey, such as larger birds, are killed by a sprint followed by a leap to catch them as they are trying to flee, and are eaten slowly. Servals have been observed caching large kills to be consumed later by concealing them in dead leaves and grasses. Servals typically get rid of the internal organs of rodents while eating, and pluck feathers from birds before consuming them. During a leap, a serval can reach more than 2 metres (6 ft 7 in) above the ground and cover a horizontal distance of up to 3.6 metres (11 ft 10 in). Servals appear to be efficient hunters; a study in Ngorongoro showed that servals were successful in half of their hunting attempts, regardless of the time of hunting, and a mother serval was found to have a success rate of 62%. The number of kills in a 24-hour period averaged 15 to 16. Scavenging has been observed, but very rarely.[5][8]

Reproduction

Both sexes become sexually mature when they are one to two years old. Oestrus in females lasts one to four days; it typically occurs once or twice a year, though it can occur three or four times a year if the mother loses her litters.[32] Observations of captive servals suggest that when a female enters oestrus, the rate of urine-marking increases in her as well as the males in her vicinity. Zoologist Jonathan Kingdon described the behaviour of a female serval in oestrus in his 1997 book East African Mammals. He noted that she would roam restlessly, spray urine frequently holding her vibrating tail in a vertical manner, rub her head near the place she has marked, salivate continuously, give out sharp and short "miaow"s that can be heard for quite a distance, and rub her mouth and cheeks against the face of an approaching male. The time when mating takes place varies geographically; births peak in winter in Botswana, and toward the end of the dry season in the Ngorongoro Crater. A trend generally observed across the range is that births precede the breeding season of murid rodents.[5]

Gestation lasts for two to three months, following which a litter of one to four kittens is born. Births take place in secluded areas, for example in dense vegetation or burrows abandoned by aardvarks and porcupines. Blind at birth, newborn weigh nearly 250 grams (9 oz) and have soft, woolly hair (greyer than in adults) and unclear markings. The eyes open after nine to thirteen days. Weaning begins after a month of birth; the mother brings small kills to her kittens and calls out to them as she approaches the "den".[5] A mother with young kittens rests for a notably lesser time and has to spend almost twice the time and energy for hunting than do other servals.[28] If disturbed, the mother will shift her kittens one by one to a more secure place.[20] Kittens eventually start accompanying their mother to hunts. At around six months, they acquire their permanent canines and begin to hunt themselves; they leave their mother at about 12 months of age. They may reach sexual maturity from 12 to 25 months of age.[5] Life expectancy is about 10 years in the wild, and up to 20 years in captivity.[33]

Threats and conservation

The IUCN (International Union for Conservation of Nature and Natural Resources) lists the serval as least concern; the animal is also included in CITES Appendix II. A major threat to the survival of the serval include the degradation of wetlands and grasslands. Trade of serval skins, though on the decline, still occurs in countries such as Benin and Senegal. In western Africa, the serval has significance in traditional medicine. Pastoralists often kill servals to protect their animals, though servals generally do not prey upon livestock.[1]

Servals occur in several protected areas across its range. Hunting of servals is prohibited in Algeria, Botswana, Congo, Kenya, Liberia, Morocco, Mozambique, Nigeria, Rwanda, Cape Province (South Africa), and Tunisia; regulations apply in Angola, Burkina Faso, Central African Republic, the Democratic Republic of the Congo, Ghana, Malawi, Senegal, Sierra Leone, Somalia, Tanzania, Togo and Zambia.[1]

In culture

The association of servals with human beings dates to the time of Ancient Egypt.[34] Servals are depicted as gifts or traded objects from Nubia in Egyptian art.[35]

Like many other species of felid, servals are occasionally kept as pets, although their wild nature means that ownership of servals is regulated in most countries.[36][37][38][39][40][41][42][43][44]

Hybrid

On 7 April 1986, a healthy hybrid kitten between a male serval and a female domestic cat was born; this kitten was larger than a typical domestic kitten and resembled its father in its coat pattern. It appeared to have inherited a few domestic traits, such as tameness, from its mother. The hybrid cat may have a doglike habit of following its owner about, and can be a good swimmer. Over the years, the savannah cat, a hybrid between domestic cat and serval, has gained popularity as a pet.[45][46]

African golden cat

The African golden cat (Caracal aurata) is a wild cat endemic to the rainforests of West and Central Africa. It is threatened due to deforestation and bushmeat hunting and listed as Vulnerable on the IUCN Red List.It is a close relative of both the caracal and the serval. Previously, it was placed in the genus Profelis.Its body size ranges from 61 to 101 cm (24 to 40 in) with a 16 to 46 cm (6.3 to 18.1 in) long tail.

Battle of Ifoghas

The Battle of Ifoghas, also known as the Battle of Tigharghâr or the Battle of the Ametettai, took place from 18 February to 31 March 2013, during the Northern Mali conflict. The French army and the Chadian army fought armed Salafist jihadist groups led by Al Qaeda in the Islamic Maghreb and Ansar Dine. After being defeated in January in the Battle of Konna and the Battle of Diabaly , the jihadists abandoned Timbuktu and retreated into the Adrar Tigharghar, a mountain of the Adrar of Ifoghas in northeastern Mali, which has been their sanctuary for years. The French started quickly a pursuit, and they took control of the towns of Tessalit and Aguelhok and begun the operation Panther in the Tigharghar. The first clashes erupt on February 18 and are mainly concentrated in the Ametettai Valley. It is caught between two armored columns, one French to the west and another Chadian to the east, while the paratroopers manage to surprise the jihadists by attacking on foot from the north. The valley is taken on March 3 and jihadists begin to gradually abandon the Tigharghar. Excavation missions and some skirmishes, however, continue to take place the following days. The operations cease on March 31. The battle was a turning point in the war, as with the capture of the Tigharghar, the jihadists lose their main sanctuary in the Sahel as well as most of their military arsenal, taken from the Malian army or Libya .

Battle of Timbuktu

The Battle of Timbuktu occurred in Timbuktu, Mali, in March 2013, between Islamist groups and Mali government forces supported by France.

On the night of March 20 to 21, a group of Islamist militants tried to infiltrate the airport. A car with armed men also tried to break into the city, however, French and Malian forces pushed them back.

Caracal (genus)

Caracal is a genus of the subfamily Felinae in the family Felidae. Previously, it was considered to be a monotypic genus, consisting of only the type species: Caracal caracal, commonly called caracal.

Genetic analysis has shown that caracal, African golden cat and serval are genetically closely related and diverged from a common ancestor about 5.4 million years ago. Therefore, it has been suggested to subordinate all of them to the genus Caracal. This taxonomic classification is used in the IUCN Red List for the African golden cat. It is used as a synonym for the serval.

Caraval

The caraval (also called a cara-serval) is the cross between a male caracal and a female serval. They have a spotted pattern similar to the Serval, but on a darker background. These are bred for the pet market.

A servical is the cross between a male serval and a female caracal. A litter of servicals occurred by accident when the two animals were kept in the same enclosure at a Los Angeles zoo. The hybrids were given to an animal shelter. The only photos show them as tawny kittens.

These hybrids can theoretically be backcrossed to their parent species in various ways:

Ser-caraval (¾ serval, ¼ caracal) - a cross between a male serval and a female caraval.

Car-servical (¾ caracal, ¼ serval) - a cross between a male caracal and a servical.

Ser-servicals (¾ serval, ¼ caracal) - a male serval and a female servical.

Car-caravals (¾ caracal, ¼ serval) - a male caracal and female caraval.Currently, only ser-caravals have been documented. All of these hybrids will more closely resemble the species that contributed the greater fraction of their genes.

Dassault Mirage 2000N/2000D

The Dassault Mirage 2000N is a variant of the Mirage 2000 designed for nuclear strike. It formed the core of the French air-based strategic nuclear deterrent. The Mirage 2000D is its conventional attack counterpart.

Felid hybrid

A felid hybrid is any of a number of hybrid between various species of the cat family, Felidae. This article deals with hybrids between the species of the subfamily Felinae (feline hybrids). For hybrids between two species of the genus Panthera (lions, tigers, jaguars, and leopards), see Panthera hybrid. There are no known hybrids between Neofelis (the clouded leopard) and other genera. By contrast, many genera of Felinae are interfertile with each other, though few hybridize under natural conditions, and not all combinations are likely to be viable (e.g. between the tiny rusty-spotted cat and the leopard-sized cougar).

Gor, Granada

Gor is a town of Granada, in southwestern Spain. It consists of the town center and several suburbs scattered all over its municipal area, such as Las Juntas, Las Viñas, Cenascuras, Los Balcones, La Rambla Valdiquín, Los corrales, El Royo Serval and La Estación de Gorafe. Situated at an altitude of between 1,100 m and 2,100 m above sea level and with an extension of 182 km², Gor has a long history of human settlements that date back to the Paleolithic. The official population of Gor in 2005 was 997.

LIV (SO) Serval

The Rheinmetall LandSysteme Light Infantry Vehicle for Special Operations, or LIV (SO), is a German light armoured utility vehicle developed from the Mercedes-Benz G-Class. It is also known by the names serval, Wolf and AGF. As the name implies, the LIV (SO) is designed specifically for use by special operations forces, and has light armour, high mobility and high firepower. Development of the vehicle started in 2002, and 21 were procured by the German Army for the KSK special forces in 2004. An unspecified number of vehicles were delivered to the Swiss Army in 2007.

La Chapelle-en-Serval

La Chapelle-en-Serval is a commune in the Oise department in northern France.

Operation Serval

Operation Serval (French: Opération Serval) was a French military operation in Mali. The aim of the operation was to oust Islamic militants from the north of Mali, who had begun a push into the center of Mali.Operation Serval followed the United Nations Security Council Resolution 2085 of December 20, 2012 and an official request by the Malian interim government for French military assistance. The operation ended on July 15, 2014, and was replaced by Operation Barkhane, launched on August 1, 2014 to fight Islamist fighters in the Sahel. Three of the five Islamic leaders, Abdelhamid Abou Zeid, Abdel Krim and Omar Ould Hamaha were killed, while Mokhtar Belmokhtar fled to Libya and Iyad ag Ghali fled to Algeria.The operation is named after the medium-sized African wild cat species Serval.

Savannah cat

The Savannah is a hybrid cat breed. It is a cross between a serval and a domestic cat.

Serengeti cat

The Serengeti is a breed of domestic cat, first developed by crossing a Bengal (domestic and wild hybrid) and an Oriental Shorthair. Recognized and registered by The International Cat Association (TICA), no other first generation crosses can be registered as Serengeti. From the Bengal × Oriental cross came the first foundation Serengeti. Breeders then worked with the cat to produce a cat that resembles the breed profile set by TICA.

Created by Karen Sausman of Kingsmark Cattery in California in 1994, the breed is still in the development stages, but the ultimate aim is to produce a cat that looks similar to a serval, without using any recent wild cat blood. (Bengal cats originate from hybridization of leopard cats and domestic cats. Most Bengal cats used in Serengeti breeding programs are many generations removed from these origins and possess few genetic contributions of the wild forebears except alleles affecting coat color.)

Serengetis are spotted cats, with long legs and very large, round tipped ears. They have a long neck which blends with the base of the skull without tapering. Males are generally slightly larger and heavier than females and can weigh between 10 and 15 lbs; females generally weigh between 8 and 12 lbs. Because the Bengal stock is a hybrid cat, the Serengeti is also classified as a hybrid.

They are recognized by TICA in tabby, ebony silver, ebony smoke and solid black. A group of breeders in the UK are currently working towards getting TICA to also recognise the snow spotted (a.k.a. lynx point) variety.

The tabby is known as the brown-spotted in the UK. However spots can be black or dark brown on a tan, light beige or gold background. The silver has black spots on a silver background. Ghost spotting can sometimes be seen on the solid black version.

Serval, Aisne

Serval is a commune in the Aisne department in Hauts-de-France in northern France.

Serval Project

The Serval Project (often referred to as Serval) is a project financed by the Shuttleworth Foundation, as well as various other organisations and accepting individual donations. It is headquartered at Flinders University in Adelaide, Australia. The project aims to develop technology that can be used to create direct connections between cellular phones through their Wi-Fi interfaces, without the need of a mobile phone operator. The technology allows for live voice calls whenever the mesh is able to find a route between the participants. Text messages and other data can be communicated using a store and forward system called Rhizome, allowing communication over unlimited distances and without a stable live mesh connection between all participants.

The Serval Project includes a collaborate mapping application intended to support disaster relief and recovery efforts. A "mesh extender" is being developed, which establishes a short range Serval mesh over WiFi and joins it with other more distant meshes by linking to other mesh extenders over packet radio operating in the ISM 915 MHz band.
