The Pallas's cat (Otocolobus manul), also known as the manul, is a small wild cat with long and dense light grey fur, and rounded ears set low on the sides of the head. Its head-and-body length ranges from 46 to 65 cm (18 to 26 in) with a 21 to 31 cm (8.3 to 12.2 in) long bushy tail. It is well camouflaged and adapted to the cold continental climate in its native range, which receives little rainfall and experiences a wide range of temperatures.
Due to its widespread range and assumed large population, the Pallas's cat has been listed as Least Concern on the IUCN Red List since 2020. Some population units are threatened by poaching, prey base decline due to rodent control programs, and habitat fragmentation as a result of mining and infrastructure projects.
The Pallas's cat has been kept in zoos since the early 1950s. As of 2018,[update] 60 zoos in Europe, Russia, North America and Japan participate in Pallas's cat captive breeding programs.
The Pallas's cat's fur is light grey with pale yellowish-ochre or pale yellowish-reddish hues.[6] Some hair tips are white and some blackish. Its fur is greyer and denser with fewer markings visible in winter than in the summer.[14]: 668–669 The forehead and top of the head are light grey with small black spots. It has two black zigzag lines on the cheeks running from the corner of the eyes to the jaw joints.[6] Its chin, whiskers, lower and upper lips are white.[14]: 669
It has narrow black stripes on the back, consisting of five to seven dark transversal lines across the lower back.[6] Its grey tail has seven narrow black rings and a black tip.[14]: 669 The underfur is 40 mm (1.6 in) long and 19 μm thick, and the guard hairs up to 69 mm (2.7 in) long and 93 μm thick on the back. Its fur is soft and dense with up to 9,000 hairs/cm2 (58,000 hairs/in2).[14]: 666
The Pallas's cat's ears are grey with a yellowish tinge on the back and a darker rim, but with whitish hair in front and in the ear pinnae. Its rounded ears are set low on the side, such that it can peer over an object and show only a relatively small part of the head above the eyes without depressing the ears. This can give its face a look of ferocity and unrest.[10] Its eyes are encircled by white. The iris is yellowish, and its pupils contract to small circular disks in sunlight.[10]: 301 Among the Felinae, it shares this trait of round pupils with Puma, Herpailurus and Acinonyx species.[15]
The Pallas's cat is about the size of a domestic cat (Felis catus).[6] Its stocky posture with the long and dense fur make it appear stout and plush. Its head-to-body is 46 to 65 cm (18 to 26 in) long with a 21 to 31 cm (8.3 to 12.2 in) long tail. It weighs 2.5 to 4.5 kg (5 lb 8 oz to 9 lb 15 oz).[16]
Its body is stout, and its skull is rounded with a short nasal bone, an enlarged cranial part and rounded zygomatic arches. Its orbits are large and directed forward. Its legs are short with short and sharp retractile claws.[17]
The skull of males is 87–95 mm (3.4–3.7 in) long and 66–74 mm (2.6–2.9 in) wide at the base. Females have a 84–96 mm (3.3–3.8 in) long and 65–68 mm (2.6–2.7 in) wide skull.[14]: 671–674 The lower carnassial teeth are powerful, and the upper carnassials are short and massive. The first pair of upper premolars is absent. The dental formula is 3.1.2.13.1.2.1 × 2 = 28.[17] It has a bite force at the canine tip of 155.4 newtons and a bite force quotient at the canine tip of 113.8.[18]
The Pallas's cat's range extends from the Caucasus eastward to Central Asia, Mongolia and adjacent parts of Dzungaria and the Tibetan Plateau. It inhabits montane shrublands and grasslands, rocky outcrops, screeslopes and ravines in areas, where the continuous snow cover is below 15–20 cm (6–8 in).[14]
In the southwestern part of its range, the habitat of the Pallas's cat is affected by cold and dry winters, and moderate to low rainfall in warm summers.[20] The typical vegetation in this part consists of small shrubs, sagebrush (Artemisia), Festuca and Stipa grasses.[14]
In the central part of its range, it inhabits hilly landscapes, high plateaus and intermontane valleys that are covered by dry steppeorsemi-desert vegetation, such as low shrubs and xerophytic grasses.[21] The continental climate in this region exhibits a range of 80 °C (140 °F) between the highest and lowest air temperatures, dropping to −50 °C (−58 °F) in winter.[14]: 684–688
The Greater Caucasus region is considered climatically suitable for the Pallas's cat.[20]InArmenia, an individual was killed near Vedi in the mountains of Ararat Province in the late 1920s.[17] In January 2020, an individual was sighted about 140 km (90 mi) farther north in Tavush Province; the habitat at this location transitions from semi-desert to montane steppe at an elevation of about 570 m (1,900 ft).[22] Records in Azerbaijan are limited to a Pallas's cat skin found in Karabakh and a sighting of an individual in Julfa District, both in the late 20th century.[23]
The Pallas's cat inhabits rocky slopes in the Koh-i-Baba Range of the Hindu Kush.
On the Iranian Plateau, two Pallas's cats were encountered near the Aras River in northwestern Iran before the 1970s.[14] In the area, an individual was captured at an elevation of about 1,500 m (5,000 ft) near AzarshahrinEast Azerbaijan Province in 2008.[23] In the same year, a camera trap recorded a Pallas's cat on the southern slopes of the central Alborz MountainsinKhojir National Park shortly after heavy snowfall.[24] Farther east in the Alborz Mountains, an individual was recorded among rocks at an elevation of 2,441 m (8,009 ft) in 2016.[25] In the Aladagh and Kopet Dag Mountains, the Pallas's cat was recorded inside and in the vicinity of protected areas.[26] In the south of the Zagros Mountains, an individual was caught in a corral used by transhumant pastoralists in Abadeh County in 2012. The surrounding area consists of rocky steppe habitat dominated by mountain almond (Prunus scoparia), Astragalus and Artemisia.[27]
In the Hindu Kush, a Pallas's cat was observed sunbathing at the fringe of a rocky high-elevation plain near Dasht-e NawarinAfghanistan's Koh-i-Baba range in April 2007.[28] The Pallas's cat was also photographed multiple times in Bamyan Province between 2015 and 2017.[20]InPakistan's Qurumber National ParkinGilgit-Baltistan, an individual was recorded on a ridge in a juniper dominated forest at 3,445 m (11,302 ft) in July 2012.[29]
The Pallas's cat occurs in alpine pastures of the upper Marshyangdi river valley in the central Himalayas.
The presence of the Pallas's cat in the Himalayas was first reported in Ladakh's Indus valley in 1991.[46]InChangthang Wildlife Sanctuary, Pallas's cats were sighted close by riverbanks at elevations of 4,202 and 4,160 m (13,786 and 13,648 ft) in 2013 and 2015.[47]InGangotri National Park, a Pallas's cat was photographed in rocky alpine scrub at 4,800 m (15,700 ft) in 2019.[48]InSikkim, an individual was observed on a rocky slope at an elevation of 5,073 m (16,644 ft) in the vicinity of Tso Lhamo Lake in 2007.[49]
In December 2012, the Pallas's cat was recorded for the first time in the Nepal Himalayas. It was photographed in the upper Marshyangdi river valley in alpine pastures at elevations of 4,200 m (13,800 ft) and 4,650 m (15,260 ft) in Annapurna Conservation Area.[50]InShey-Phoksundo National Park, Pallas's cat scat was detected at 5,593 m (18,350 ft) in 2016, the globally highest record to date.[51]
In January 2012, it was recorded for the first time in Bhutan, namely in rolling hills dominated by glacial outwash and alpine steppe vegetation in Wangchuck Centennial National Park.[52] In autumn 2012, it was also photographed at an elevation of 4,122 m (13,524 ft) in Jigme Dorji National Park.[53] In 2019, scat samples of two individuals were found in Sagarmatha National Park, providing the first genetic evidence of the cat's presence in the eastern Himalayas.[54]
The Pallas's cat is solitary.[14] Of nine Pallas's cat kittens observed in captivity, only the two males scent marked by spraying urine.[55]
The Pallas's cat uses caves, rock crevices and marmot burrows as shelter.[14]: 690–691 In central Mongolia, 29 Pallas's cats were fitted with radio collars between June 2005 and October 2007. They used 101 dens during this time, including 39 winter dens, 42 summer dens and 20 dens for raising kittens. The summer and winter dens usually had one entrance with a diameter of 15.6 to 23.4 cm (6.1 to 9.2 in). They resided in the summer dens for 2–21 days, and in the winter dens for 2–28 days. Summer and maternal dens were close to rocky habitats with little direct sunlight, whereas winter dens were closer to ravines.[56] The home ranges of 16 females varied from 7.4 to 125.2 km2 (2.9 to 48.3 sq mi). The home ranges of nine males varied from 20.9 to 207.0 km2 (8.1 to 79.9 sq mi) and overlapped those of one to four females and partly also those of other males. The sizes of their home ranges decreased in winter.[39]
In an unprotected area in central Mongolia, Pallas's cats were mainly crepuscular between May and August, but active by day from September to November.[57] Pallas's cats recorded in four study areas in the western Mongolian Altai mountains were also active during the day, but with a lower frequency at sites where livestock was present.[58]
The Pallas's cat is a highly specialised predator of small mammals, which it catches by stalking or ambushing near exits of burrows. It also pulls out rodents with its paws from shallow burrows. In the Altai Mountains, remains of long-tailed ground squirrel (Urocitellus undulatus), flat-skulled shrew (Sorex roboratus), Pallas's pika (Ochotona pallasi) and bird feathers were found near breeding burrows of Pallas's cats. In Transbaikal, it preys on Daurian pika (Ochotona dauurica), steppe pika (O. pusilla), Daurian ground squirrel (Spermophilus dauricus) and young of red-billed chough (Pyrrhocorax pyrrhocorax).[14]
Scat samples of the Pallas's cat collected in the bufferzone of Khustain Nuruu National Park in central Mongolia contained foremost remains of Daurian pika, Mongolian gerbil (Meriones unguiculatus), Mongolian silver vole (Alticola semicanus) and remains of passerine birds, beetles and grasshoppers.[59]Brandt's vole (Lasiopodomys brandtii) dominated in the diet of Pallas's cats in Mongolia's Sükhbaatar Province after the irruptive growth of this vole population during 2017 to 2020.[60]
Scat found in Shey-Phoksundo National Park contained remains of pika species and of woolly hare (Lepus oiostolus).[51] Remains of a cypriniform fish were found in Pallas's cat scat in Gongga Mountain Nature Reserve.[61]
A captive male Pallas's cat housed under natural lighting conditions showed increased aggressive and territorial behaviour at the onset of the breeding season, lasting from September to December. Its blood contained three times more testosterone than in the non-breeding season, and its ejaculate was more concentrated with more normal sperm forms and a higher motility of sperm.[64]
In the wild, the female gives birth to a litter of two to six kittens between the end of April and late May. The newborn kittens' fur is fuzzy, and their eyes are closed until the age of about two weeks.[14]: 693 A newborn male kitten born in a zoo weighed 89 g (3.1 oz), measured 12.3 cm (4.8 in) and had a 5.5 cm (2.2 in) long tail.[62]
In central Mongolia, seven females with kittens were observed using 20 dens for 4–60 days. Their maternal dens were either among rocks, or in former burrows of the Tarbagan marmot (Marmota sibirica), and had at least two entrances.[56] In Iran, a Pallas's cat was observed using cavities of aged Greek juniper (Juniperus excelsa) as breeding dens for a litter of four kittens.[65]
Two-month-old kittens weigh 500–600 g (17.6–21.2 oz), and their fur gradually grows longer. They start hunting at the age of about five months and reach adult size by the age of six to seven months.[14]: 694
In China, Mongolia and Russia, the Pallas's cat was once hunted for its fur in large numbers of more than 10,000 skins annually. In China and the former Soviet Union, hunting of the Pallas's cat decreased in the 1970s when it became legally protected. Mongolia exported 9,185 skins in 1987, but international trade has ceased since 1988.[66] However, domestic trade of its skins and body parts for medicinal purposes continues in the country, and it may be hunted throughout the year.[67]
Cases of herding dogs killing Pallas's cats were reported in Iran, Kazakhstan and the Altai Republic.[26][33][21]
Pallas's cats have also fallen victim in traps set for small mammals in Kazakhstan and in the Altai Republic. In Transbaikal, the Pallas's cat is threatened by poaching. In Mongolia, the use of the rodenticidebromadiolone in the frame of rodent control measures in the early 21st century poisoned the prey base of carnivores and raptors.[21]
In the Sanjiangyuan region of the Tibetan Plateau, 54,147 km2 (20,906+1⁄4 sq mi) of grassland was poisoned between 2005 and 2009, leading to an estimated loss of 50,000–80,000 tonnes (55,000–88,000 short tons) of pika biomass.[68]
The Pallas's cat may be negatively affected by habitat fragmentation due to mining and infrastructure projects.[2]
Conservation
[edit]Pallas's cat on the Russian Federation two-ruble coin, silver, reverse.
On the IUCN Red List, the Pallas's cat is classified as Least Concern since 2020 because of its wide-spread range and assumed large global population. It is listed in CITES Appendix II. Hunting it is prohibited in all range countries except Mongolia. Since 2009, it is legally protected in Afghanistan, where all hunting and trade with its body parts is banned.[2]
On the Mongolian Red List of Mammals, it is listed as Near Threatened since 2006.[67] In China, it is listed as Endangered.[69] In Turkmenistan, it is proposed to be listed as Critically Endangered due to the scarcity of contemporary records.[70]
Zoos in the former Soviet Union received most of the wild-caught Pallas's cats from the Transbaikal region and a few from Mongolia. Moscow Zoo initiated a studbook for the Pallas's cat in 1997. Since 2004, the Pallas's cat international studbook has been managed by the Royal Zoological Society of Scotland, which also coordinates the captive breeding program for the Pallas's cat within the European Endangered Species Programme. As of 2018, 177 Pallas's cats were kept in 60 zoos in Europe, Russia, North America and Japan.[74]
The Pallas's cat is featured in a Russian Internet meme known as "Pet the cat" introduced in 2008; the meme is a picture of a Pallas's cat that invites the reader to pet it in the image's caption.[77][78] In 2012, the Pallas's cat became the mascot of Moscow Zoo.[79]
