The Asiatic cheetah (Acinonyx jubatus venaticus), also known as Iranian or Persian 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, Pakistan and India, but has been extirpated there during the 20th century.
The Asiatic cheetah survives in protected areas in the eastern-central arid region of Iran, where the human population density is very low. Between December 2011 and November 2013, 84 individuals were sighted in 14 different protected areas, and 82 individuals were identified from camera trap photographs. As of December 2017, fewer than 50 individuals are thought to be remaining in three subpopulations that are scattered over 140,000 km2 (54,000 sq mi) in Iran's central plateau. In order to raise international awareness for the conservation of the Asiatic cheetah, an illustration was used on the jerseys of the Iran national football team at the 2014 FIFA World Cup.
The Asiatic cheetah diverged from the cheetah population in Africa between 32,000 and 67,000 years ago. During the British colonial times in India, it was called hunting leopard, a name derived from the ones that were kept in captivity in large numbers by Indian royalty to use for hunting wild antelopes.
Taxonomy[]
Felis venatica was proposed by Edward Griffith in 1821 and based on a sketch of a maneless cheetah from India. Griffith's description was published in Le Règne Animal with the help of Griffith's assistant Charles Hamilton Smith in 1827. Acinonyx raddei was proposed by Max Hilzheimer in 1913 for the cheetah population in Central Asia, the Trans-Caspian cheetah. Hilzheimer's type specimen originated in Merv, Turkmenistan.
Evolutionary History[]
Results of a five-year phylogeographic study on cheetah subspecies indicate that Asiatic and African cheetah populations separated between 32,000 and 67,000 years ago and are genetically distinct. Samples of 94 cheetahs for extracting mitochondrial DNA were collected in nine countries from wild, seized and captive individuals and from museum specimen. The population in Iran is considered autochthonous monophyletic and the last remaining representative of the Asiatic subspecies.
Characteristics[]
The Asiatic cheetah has a buff- to light fawn-coloured fur that is paler on the sides, on the front of the muzzle, below the eyes and inner legs. Small black spots are arranged in lines on the head and nape, but irregularly scattered on body, legs, paws and tail. The tail tip has black stripes. The coat and mane are shorter than of African cheetah subspecies. The head and body of an adult Asiatic cheetah measure about 112–135 cm (44–53 in) with a 66–84 cm (26–33 in) long tail. It weighs about 34–54 kg (75–119 lb). Males are slightly larger than the females.
The cheetah is the fastest land animal in the world. It was previously thought that the body temperature of a cheetah increases during a hunt due to high metabolic activity. In a short period of time during a chase, a cheetah may produce 60 times more heat than at rest, with much of the heat, produced from glycolysis, stored to possibly raise the body temperature. The claim was supported by data from experiments in which two cheetahs ran on a treadmill for minutes on end but contradicted by studies in natural settings, which indicate that body temperature stays relatively the same during a hunt. A 2013 study suggested stress hyperthermia and a slight increase in body temperature after a hunt.[19] The cheetah's nervousness after a hunt may induce stress hyperthermia, which involves high sympathetic nervous activity and raises the body temperature. After a hunt, the risk of another predator taking its kill is great, and the cheetah is on high alert and stressed. The increased sympathetic activity prepares the cheetah's body to run when another predator approaches. In the 2013 study, even the cheetah that did not chase the prey experienced an increase in body temperature once the prey was caught, showing increased sympathetic activity.
Distribution and Habitat[]
The cheetah thrives in open lands, small plains, semi-desert areas, and other open habitats where prey is available. The Asiatic cheetah mainly inhabits the desert areas around Dasht-e Kavir in the eastern half of Iran, including parts of the Kerman, Khorasan, Semnan, Yazd, Tehran, and Markazi provinces. Most live in five protected areas, viz Kavir National Park, Touran National Park, Bafq Protected Area, Dar-e Anjir Wildlife Refuge, and Naybandan Wildlife Reserve.
During the 1970s, the Asiatic cheetah population in Iran was estimated to number about 200 individuals in 11 protected areas. By the end of the 1990s, the population was estimated at 50 to 100 individuals. During camera-trapping surveys conducted across 18 protected areas between 2001 and 2012, a total of 82 individuals in 15–17 families were recorded and identified. Of these, only six individuals were recorded for more than three years. In this period, 42 cheetahs died due to poaching, in road accidents and due to natural causes. Populations are fragmented and known to survive in the Semnan, North Khorasan, South Khorasan, Yazd, Esfahan, and Kerman Provinces. In summer 2018, a female cheetah and four cubs were sighted in Touran Wildlife Refuge Iran's Semnan province.
Ecology and Behavior[]
Most sightings of cheetahs in the Miandasht Wildlife Refuge between January 2003 and March 2006 occurred during the day and near watercourses. These observations suggest that they are most active when their prey is. Camera-trapping data obtained between 2009 and 2011 indicate that some cheetahs travel long distances. A female was recorded in two protected areas that are about 150 km (93 mi) apart and intersected by railway and two highways. Her three male siblings and a different adult male were recorded in three reserves, indicating that they have large home ranges.
Diet[]
The Asiatic cheetah preys on medium-sized herbivores including chinkara, goitered gazelle, wild sheep, wild goat and cape hare. In Turan Biosphere Reserve, cheetahs use a wide range of habitats, but prefer areas close to water sources. This habitat overlaps to 61% with wild sheep, 36% with onager, and 30% with gazelle. In India, prey was formerly abundant. Before its extinction in the country, the cheetah fed on the blackbuck, the chinkara, and sometimes the chital and the young nilgai.
Reproduction[]
Evidence of females successfully raising cubs is very rare. A few observations in Iran indicate that they give birth throughout the year to one to four cubs. In April 2003, four cubs were found in a den that had their eyes still closed. In November 2004, a cub was recorded by a camera-trap that was about 6–8 months old. Breeding success depends on availability of prey. In January 2008, a male cub aged about 7–8 months was recovered from a sheep herder and brought into captivity.
In October 2013, conservationists from the Persian Wildlife Heritage Foundation filmed a mother with four cubs in Khar Turan National Park. In December 2014, four cheetahs were sighted and photographed by camera traps in the same national park. In January 2015, three other adult Asiatic cheetahs and a female with her cub were sighted in Miandasht Wildlife Refuge. Eleven cheetahs were also sighted at the time, and another four a month later. In July 2015, five adult cheetahs and three cubs were spotted in Khar Turan National Park.
The Asiatic cheetah population is considered to be on the rise. In December 2015, it is reported that 18 new Asiatic cheetah cubs had recently been born and it was hoped for two captive Asian cheetahs at Pardisan Park would produce cubs.
Threats[]
The Asiatic cheetah has been listed as Critically Endangered on the IUCN Red List since 1996.[1] Following the Iranian Revolution of 1979, wildlife conservation was interrupted for several years. Manoeuvres with armed vehicles were carried in steppes, and local people hunted cheetahs and prey species unchecked. The gazelle population declined in many areas, and cheetahs retreated to remote mountainous habitats.
Reduced gazelle numbers, persecution, land-use change, habitat degradation and fragmentation, and desertification contributed to the decline of the cheetah population. The cheetah is affected by loss of prey as a result of antelope hunting and overgrazing from introduced livestock. Its prey was pushed out as herders entered game reserves with their herds. A herder pursued a female cheetah with two cubs on his motorbike, until one of the cubs was so exhausted that it collapsed. He caught and kept it chained in his home for two weeks, until it was rescued by officers of the Iranian Department of Environment.
Mining development and road construction near reserves also threaten the population. Coal, copper, and iron have been mined in cheetah habitat in three different regions in central and eastern Iran. It is estimated that the two regions for coal (Nayband) and iron (Bafq) have the largest cheetah population outside protected areas. Mining itself is not a direct threat to the population; road construction and the resulting traffic have made the cheetah accessible to humans, including poachers. The Iranian border regions to Afghanistan and Pakistan, viz the Baluchistan Province, are major passages for armed outlaws and opium smugglers who are active in the central and western regions of Iran, and pass through cheetah habitat. Uncontrolled hunting throughout the desert cannot be effectively controlled by the governments of the three countries.
Conflict between livestock herders and cheetahs is also threatening the population outside protected areas. Several herders killed cheetahs to prevent livestock loss, or for trophies, trade and fun. Some herders are accompanied by large mastiff-type dogs into protected areas. These dogs killed five cheetahs between 2013 and 2016.
Between 2007 and 2011, six cheetahs, 13 predators and 12 Persian gazelles died in Yazd Province following collisions with vehicles on a transit road. At least 11 Asiatic cheetahs were killed in road accidents between 2001 and 2014. The road network in Iran constitutes a very high risk for the small population as it impedes connectivity between population units. Efforts to stop the construction of a road through the core of the Bafq Protected Area were unsuccessful.
