The Mongolian gerbil or Mongolian jird (Meriones unguiculatus) is a small rodent belonging to the subfamily Gerbillinae.[3] Their body size is typically 110–135mm (4½" to v¼"), with a 95–120mm (3¾" to 4¾") tail, and body weight sixty–130g (2 to 4½ oz), with adult males larger than females.[4] The animal is used in science and kept as a small firm pet. Their utilise in science dates back to the latter one-half of the 19th century, but they only started to be kept as pets in the English-speaking world afterwards 1954, when they were brought to the USSR. Yet, their use in scientific enquiry has fallen out of favor.

Habitat [edit]

Mongolian gerbils inhabit grassland, shrubland and desert, including semidesert and steppes in China, Mongolia, and the Russian Federation.[five]

Soil on the steppes is sandy and is covered with grasses, herbs, and shrubs. The steppes have cool, dry winters and hot summers. The temperature can become up to l °C (122 °F), merely the average temperature for most of the year is around xx °C (68 °F).[six] [ self-published source? ]

In the wild, these gerbils live in patriarchal groups generally consisting of i parental pair, the most recent litter, and a few older pups, sometimes the dominant female's sister(south) also live with them. Only the dominant females volition produce pups, and will mostly mate with the dominant male while in heat (heat), female person gerbils are generally more than loyal than male person gerbils. Ane group of gerbils more often than not ranges over 325–ane,550 foursquare metres (400–1,900 sq yd).[7]

A group lives in a fundamental burrow with 10–xx exits. Some deeper burrows with only one to three exits in their territory may exist. These deeper burrows are used to escape from predators when they are too far from the key burrow. A group's burrows ofttimes interconnect with other groups.[ citation needed ]

History [edit]

The first known mention of gerbils came in 1866, by Father Armand David, who sent "yellowish rats" to the French National Museum of Natural History in Paris, from northern Prc. They were named Gerbillus unguiculatus by the scientist Alphonse Milne-Edwards in 1867.[2]

In that location is a popular misconception about the meaning of this scientific proper noun, appearing both in printed works[eight] and in websites,[9] due to the genus Meriones sharing the name with Greek warrior Meriones in Homer'south Iliad; however, translations similar "clawed warrior" are wrong. The genus was named by Johann Karl Wilhelm Illiger in 1811,[ten] deriving from the Greek word μηρος (femur). Combined with 'unguiculate', meaning to have claws or nails in Latin, the name can exist loosely translated as 'clawed femur'.[11]

Gerbils only became pop pets in the English-speaking earth after 1954, when twenty males and 26 females were brought to the United States from eastern Mongolia for scientific testing. Most all pet gerbils today are descended from them. Gerbils were brought to the Britain in 1964 from the United States.

In science [edit]

Gerbils have a long history of utilise in scientific research, although nowadays they are rarely used. For example, in the United Kingdom in 2017, only around 300 Mongolian gerbils were used in experimental procedures, compared to over ii million mice.[12]

Tumblebrook Subcontract [edit]

Most gerbils used in scientific research are derived from the Tumblebrook Farm strain, which has its origins in xx pairs of wild-caught Mongolian gerbils sent to Japan in 1935. Xi of these animals were afterward sent to Tumblebrook Subcontract in the U.s.a., with additional animals later on sent to Charles River Ltd in Italia in 1996.[13] [14] [15]

Hearing [edit]

Gerbils have a wide hearing range, from detection of low frequency human foot drumming to higher frequency chirps and therefore may be a more suitable model of human hearing loss than mice and rats, which are high-frequency specialists.[16]

Vocal [edit]

Male gerbils can produce ultrasonic sounds with frequencies ranging from approximately 27 to 35 kHz and amplitudes ranging from approximately 0 to seventy dBa. Their larynx is involved in the product of these ultrasonic sounds. Experimentation revealed five findings of involvement, which are that adults merely emit ultrasonic sounds when stimulated socially, males signal more oftentimes than females, dominant males are more active in vocalizations than subordinate males, ultrasounds are triggered past conspecific odors, and d-amphetamine, a central nervous arrangement stimulant, contributes high levels of ultrasounds and chlorpromazine, an antipsychotic medication, lowers the emission charge per unit. In addition, there's been a human relationship betwixt the ultrasonic sounds and their ability to reproduce.[17]

Epilepsy [edit]

10–twenty% of gerbils exhibit spontaneous epileptiform seizures, typically in response to a stressor such every bit treatment or cage cleaning.[18] Epilepsy in gerbils has a genetic basis, and seizure-decumbent and seizure-resistant lines have been bred.[xix] [xx]

Diabetes [edit]

Like other desert rodents such every bit fatty sandrats, Mongolian gerbils are susceptible to diet-induced diabetes, although incidence is low.[21] A diabetes-prone line has recently been generated, showing that gerbil diabetes has at least some genetic basis.[22] [23]

Genetics and genomics [edit]

Laboratory gerbils are derived from a small number of founders, and so genetic diversity was by and large assumed to be depression. Initial genetic studies based on small numbers of genetic markers appeared to support this,[24] [25] but more recent genome-wide Genotyping-past-Sequencing (GBS) information has shown that genetic diversity is actually quite high.[13] It has been suggested that laboratory gerbils should be considered domesticated, and designated "M. unguiculatus forma domestica" to differentiate them from wildlife.[26] A Mongolian gerbil genome sequence was published in 2018[27] and a genetic map comprising 22 linkage groups (one per chromosome) in 2019.[28]

Reproduction [edit]

These rodents are widely used as subjects of testing within laboratories for a plethora of different reasons.[29] These rodents are susceptible to carrying diseases and infections some transmitted sexually, much the subject of many experiments within labs.[30] In the wild, Wild Mongolian gerbils breed during the months of Feb and October. Males practice not go sexually mature for about 70–eighty days, while the vaginal opening occurs in females about 33–fifty days after birth.[31] For other gerbils such every bit the hairy footed gerbil, sexual maturity has a slightly earlier and longer window of 60-90[32] days in comparing with a later and shorter window for Mongolian gerbils, 70–84 days.[31] Females reach sexual maturity before long after this opening occurs. They experience oestrus cycles every 4–6 days. Mongolian gerbils are regarded as monogamous inside science.[33] Fifty-fifty with this said, many Mongolian Gerbils have nevertheless been found in laboratory tests regarding their sexual reproduction behavior to have shown signs of promiscuity and mating with other females while their monogamous partner is absent in laboratory setting.[33] Gerbils are for the nearly part selective when it comes to picking a mate for copulation; though their selection process occurs more rapid than other species due to the high amount of gerbil population and shorter life bridge. An average litter size for the Mongilian Gerbil would be around 4–8 pups, if the litter merely contains around 1–two immature and then the female parent will neglect them and they will die from starvation.[33] Mongolian Gerbils are monogamous and mate with their selected partner for the rest of their time together, when 1 becomes widowed many gerbils refrain from seeking other mates to reproduce with.[33] Males generally notice new mates whereas females may not. When older females lose their mate they nearly always give up on seeking reproduction.[33] Their behavior tends to vary when faced with different settings, inside the wild finding and selecting a mate is not a problem at all due to the loftier frequency of mates. Inside a laboratory setting many gerbils tend to keep to themselves and refrain from copulation.[33]

Behavior [edit]

Gerbils are social animals, and live in groups in the wild.[34] They rely on their sense of aroma to identify other members of their association, so information technology is important to use what is commonly referred to as the "split tank method" (or splitcaging) when introducing gerbils from separate litters.[35] Gerbils are known to set on and oftentimes impale those conveying an unfamiliar scent.[36]

As pets [edit]

Two gerbils in a 40-gallon tank with lots of room to dig tunnels.

A gentle and hardy animal, the Mongolian gerbil has get a popular small firm pet. It was kickoff brought from China to Paris in the 19th century, and became a popular house pet at that place.[37] It was later on brought to the United States in 1954 by Dr. Victor Schwentker for use in enquiry.[38] Dr. Schwentker soon recognized their potential as pet animals.[39] Selective convenance for the pet trade has resulted in a wide range of different color and blueprint varieties.[twoscore] Gerbils became pop pets in the US around the tardily 1950s and were imported to the United kingdom of great britain and northern ireland in 1964, where they became popular pets too.[41] They are now found in pet shops throughout the U.k. and the US.

However, due to the threat they pose to indigenous ecosystems and existing agricultural operations, it is illegal to purchase, import, or keep a gerbil as a pet in the U.Due south. state of California.[42] It is also illegal to import the animal into New Zealand.

Housing in captivity [edit]

Mongolian gerbils prefer to live in pairs or groups rather than alone. They are social and gentle, and practice not seize with teeth readily. Every bit diggers and tunnel-makers they are amend suited to a tank with a deep substrate or bedding rather than a hamster muzzle, since the absorptive substrate is liable to be kicked upwards and out of a cage quickly.[ citation needed ]

Mongolian gerbils like to chew objects to file their perpetually growing teeth, like all rodents, and demand plenty of paper-thin items and chew toys; the cardboard will exist chewed up in to bedding and mixed with the substrate. Plastic toys and tunnels should exist avoided in-case of ingestion. Fresh vegetables should be included in pocket-size amounts as an excess may cause diarrhoea. Some vegetables are toxic to gerbils, including potatoes, onions, cabbage; a diet based on multiple seeds, e.chiliad millet and alfalfa pellet mix is sufficient.[ citation needed ]

Water should be provided with a drip-feed system to prevent accidental build-up of harmful mould in the tank environment. Care should be taken not to innovate new smells of a sudden into the tank, because the tank is considered by the gerbils to be their territory. Gerbils are active and appreciate a running or exercise wheel. Repetitive corner excavation can be minimized by providing tunnels while gerbils are in their young, determinative months. As with almost animals, they appreciate a secure, private area that is dark for sleeping.[43]

A mutual misunderstanding when purchasing a abode for pet gerbils is they tin can alive in housing designed for hamsters and mice. This is not right, every bit they need to be able to dig tunnel systems. The mutual plastic items inside of hamster and mouse cages is inappropriate for gerbils due to their ability to gnaw through it very quickly. Plastic tin crusade serious health problems for all animals if ingested, therefore many owners refrain from having whatever plastic in the tank and rely entirely on wooden toys.[44] Information from gerbil societies from throughout the world is conflicting with regards to tank sizing. Yet, a mutual minimum given appears to be 45 litres (x majestic gallons) per gerbil.[44]

Reasons for popularity [edit]

Gerbils enjoy human visitor.

The several reasons for the popularity of gerbils as household pets include: The animals are typically not aggressive, and they rarely bite unprovoked or without stress. They are small and easy to handle, since they are sociable creatures that savor the company of humans and other gerbils.[45] [46] Gerbils likewise have adapted their kidneys to produce a minimum of waste to conserve trunk fluids, which makes them very clean with little odor. Gerbils take many different artful coat patterns, such every bit pied slate, described below.

Health concerns [edit]

Teeth bug [edit]

Misalignment of incisors due to injury or malnutrition may result in overgrowth, which can cause injury to the roof of the rima oris. Symptoms include a dropped or loss of ambition, drooling, weight loss, or foul breath.[47] The teeth must be clipped past a veterinarian regularly for every bit long as required.

Trauma [edit]

Common injuries are caused by gerbils being dropped or falling, often while within of a hamster ball, which tin can cause broken limbs or a fractured spine (for which there is no cure).[47] [48]

Neglect [edit]

A common problem for all small-scale rodents is fail, which can crusade the gerbils to non receive adequate food and water, causing serious health concerns, including dehydration, starvation, tummy ulcers, eating of bedding fabric, and cannibalism.[47]

Epilepsy [edit]

Between twenty and fifty% of pet gerbils take the seizure disorder epilepsy.[49] The seizures are thought to be caused past fright, treatment, or a new environs. The attacks can be mild to astringent, merely do not typically appear to have any long-term effects, except for rare cases where death results from very astringent seizures.[50] A fashion to forbid a gerbil from having a seizure is to refrain from blowing in the animal's face (often used to "railroad train" the pet not to bite). This technique is used in a lab surroundings to induce seizures for medical research.[51]

Tumors [edit]

Tumors, both benign and malignant, are adequately mutual in pet gerbils, and are most mutual in females over the age of two. Usually, the tumors involve the ovaries, causing an extended abdomen, or the skin, with tumors virtually often developing effectually the ears, feet, midabdomen, and base of operations of the tail, actualization as a lump or abscess.[l] The olfactory property gland (positioned on the abdomen) should be checked regularly; a veterinary can operate on the lump where possible.[52]

Tail sloughing [edit]

Gerbils can lose their tails due to improper handling, being attacked past some other animal, or getting their tails stuck. The first sign is a loss of fur from the tip of the tail, then, the skinless tail dies off and sloughs, with the stump unremarkably healing without complications.[50]

Tyzzer's disease [edit]

The most common communicable diseases in gerbils is Tyzzer's illness, a bacterial affliction, which stress tin can make animals more susceptible to. Information technology produces symptoms such as ruffled fur, lethargy, hunched posture, poor appetite, diarrhoea, and often death. It rapidly spreads between gerbils in close contact.[50]

Deafness and inner ear problems [edit]

A problem with the inner ear tin be spotted by a gerbil leaning to one side quite obviously. The fluids in the ears affect balance. Nevertheless, this does non appear to impact the gerbils too much, which accept an attitude of just getting on with things, and getting used to their conditions. Gerbils with "extreme white spotting" colouring are susceptible to deafness; this is thought to be due to the lack of pigmentation in and around the ear.[53]

Convict-bred gerbils [edit]

A male and female fat-tailed gerbil (Pachyuromys duprasi)

Many color varieties of gerbils are bachelor in pet shops today, generally the result of years of selective convenance.

Over 20 different coat colors occur in the Mongolian gerbil, which has been captive-bred the longest.[54]

Another species of gerbil has also been recently introduced to the pet manufacture: the fat-tailed gerbil, or duprasi. They are smaller than the common Mongolian gerbils, and have long, soft coats and short, fat tails, appearing more like a hamster. The variation on the normal duprasi coat is more gray in color, which may be a mutation, or it may be the effect of hybrids betwixt the Egyptian and Algerian subspecies of duprasi.[55] [56]

White spotting has been reported in not only the Mongolian gerbil, but also the pallid gerbil[57] and possibly Sundervall's Jird.[58]

A long-haired mutation, a gray agouti or chinchilla mutation, white spotting, and perhaps a dilute mutation take also appeared in Shaw's jirds,[59] and white spotting and a dilute mutation have shown up in bushy-tailed jirds.[60]
