Allactodipus bobrinskii (Bobrinski's jerboa) can be found in the Palearctic region throughout northern and western areas of Turkmenistan and central and western areas of Uzbekistan. Its distribution more specifically includes the Karakumy and Kyzylkum deserts.
Biogeographic Regions: palearctic (Native )
Because its diet includes seeds, A. bobrinskii probably disperses seeds in its environment. Also, it is probably an important prey item for small-medium sized animals, such as Felis margarita and Vulpes corsac in this arid habitat.
Ecosystem Impact: disperses seeds
Although A. bobrinskii does not directly impact humans, it still carries out an important role in keeping the desert ecosystem functioning and healthy. A close relative, A. elater, is used by humans for its fur to make clothing and other items.
Because its diet includes seeds and green portions of plants, A. bobrinskii is a potential crop pest for humans. Close relatives have been known to destroy a whole crop overnight. Also, A. elater can carry and transmit disease, so this could be a potential problem too. However, since it lives in such an arid environment, A. bobrinskii is unlikely to have a significant influence on humans.
Negative Impacts: crop pest
A. bobrinskii is listed on the IUCN Red List as of least concern, suggesting that it does not need special attention for the time being.
US Federal List: no special status
CITES: no special status
State of Michigan List: no special status
IUCN Red List of Threatened Species: least concern
Bobrinski's jerboas are nocturnal and have large eyes to perceive their environment in low light. They also have very large auditory bullae which pick up low sounds extremely well. They tap theirs foot inside of the burrow, producing a low drumming noise, which may be a form of communication. In general, jerboas have a good sense of smell, vision and hearing.
Communication Channels: visual ; acoustic ; chemical
Perception Channels: visual ; tactile ; acoustic ; chemical
Bobrinski's jerboas are omnivorous, eating mostly seeds, green parts of plants, and insects. In most seasons, they forage about equally on vegetation and insects. In the spring insects become a much more significant part of the diet. They can use the hairs on their forelimbs to sift through the sand for food. Bobrinski's jerboas do not need to drink water; instead they generate metabolic water from their food.
Animal Foods: insects
Plant Foods: leaves; seeds, grains, and nuts
Primary Diet: omnivore
Allactodipus bobrinskii mainly inhabits the Kyzylkum and Karakum deserts. The Kyzylkum desert is made up of red sand while the Karakum desert is mostly salt marsh sands. Both deserts have areas of sparse vegetation and scrub. Only inhabiting loamy and hard gravel plains in these deserts, A. bobrinskii avoids fully sandy regions. These jerboas construct burrows on a slightly raised mound that is free from vegetation. A key environmental factor for this species is annual vegetation with various aspects of the local vegetation influencing species abundance.
Range elevation: 300 (high) m.
Habitat Regions: temperate ; terrestrial
Terrestrial Biomes: desert or dune
There is no information on the longevity of A. bobrinskii in either the wild or captivity. In the wild, other species of jerboas typically live for up to 2 to 3 years of age. A close relative, A. euphratica, lived 4 years and 2 months in captivity.
Typical lifespan
Status: wild: 2 to 3 years.
Bobrinski's jerboas are saltatorial with hind limbs that are elongated to 58 mm; they use their excellent jumping abilities as an anti-predator defense. While the length of a jump has not been recorded for Bobrinski's jerboas, related jerboas have been documented to jump up to 3 meters in one bound. The hind feet of Bobrinski's jerboas have three middle toes that are densely covered in a brush of stiff hairs. These stiff hairs provide some traction against the sand. Body length has been reported to be 120 mm for males and 113 mm for females with the average Bobrinski's jerboa weighing 65 grams. These jerboas have long, slender tails (165 to 170 mm) with a tuft on the end; they use their tail for balance when jumping or to prop themselves up when standing. This species has small ears (22 to 23 mm) that measure about one fifth of the body length. They have a silky coat with upper parts composed of a yellow straw colored hair that is markedly darkened in color by dark hair tips that are grey-brown. They have pure white underparts and hip patches, and the front of the head is slightly paler in color than the back. They also have protruding upper incisors and greatly inflated auditory bullae.
Average mass: 65 g.
Range length: 278 to 290 mm.
Other Physical Features: endothermic ; heterothermic ; bilateral symmetry
Sexual Dimorphism: sexes alike
Bobrinski's jerboas are relatively defenseless and will therefore use their large hind limbs and fast jumping and running abilites as an anti-predatory strategy for escape. Another defense they use is avoiding visual detection by predators. This species is nocturnal, which causes it to be safe from diurnal predators. It also has coloration that mimmicks the color of the sand in its environment; this also helps avoid predators' sight. There is no literature on the predators of A. bobrinskii, but because it is nocturnal, potential predators could include snakes and small or medium-sized nocturnal mammals. Some small-medium nocturnal mammals that inhabit A. bobrinskii areas are Felis margarita (sand cats) and Vulpes corsac (Corsac foxes).
Anti-predator Adaptations: cryptic
The mating system of A. bobrinskii is not currently known. The mating systems of other species of jerboas is also poorly documented and needs further research. This poor documentation is probably the result of their shyness.
Allactodipus bobrinskii has two observed breeding seasons: April to June and September to October. These jerboas start breeding soon after emergence from hibernation. They usually breed twice in a breeding season, which equates to about 10 offspring per breeding season. Their gestation period is on average 30 days. The weaning period of A. bobrinskii offspring is not known, but close relatives, Allactaga elater and Allactaga major, have offspring nursed and cared for up until 30 to 45 days old. The age at sexual maturity is also unknown for this species, but A. elater reaches sexual maturity at 142 days, both in males and females.
Breeding interval: Usually Bobrinski's jerboa females willl breed at least twice in a season.
Breeding season: Bobrinski's jerboas have been reported breeding in April to June and again in September to October.
Range number of offspring: 3 to 7.
Average number of offspring: 5.3.
Range gestation period: 25 to 35 days.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous
No data on parental investment have been reported for A. bobrinskii, but in a close relative, Allactaga euphratica, young receive care from their mother until they reach independence. Many species in the closely related genus g. Allactaga provide food and protection in the burrow for 1 to 1.5 months. In these species, once the offspring have reached independence, there is no parental involvement. Parental care is provided by females.
Parental Investment: altricial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female); pre-independence (Provisioning: Female, Protecting: Female)

Bobrinskis hästspringråtta (Allactodipus bobrinskii)[2][3] är en däggdjursart som beskrevs av Kolesnikov 1937. Bobrinskis hästspringråtta anses i allmänhet vara ensam i släktet Allactodipus[3], men räknas ibland i stället till släktet hästspringråttor. I vilket fall hör den till familjen hoppmöss.[4][5] IUCN kategoriserar arten globalt som livskraftig.[1] Inga underarter finns listade.[4]
Denna springråtta förekommer i centrala Asien i Kazakstan öster om resterna av Aralsjön (enligt IUCN:s karta) samt med några från varandra skilda populationer i Uzbekistan och Turkmenistan. Habitatet utgörs av öknar med lera som jordmån och med några glest fördelade växter.[1]
Arten når en kroppslängd av 11 eller 12 cm och en svanslängd av cirka 17 cm. Bakfötterna är liksom hos andra springråttor med nästan 6 cm längd påfallande stora.[6] Håren på ovansidan är gulbrun med mörkare eller gråa spetsar. På huvudet finns vita fläckar och även buken är vit. Bobrinskis hästspringråtta skiljer sig från andra hästspringråttor genom styva hår på undersidan av de tre mellersta tårna vid bakfoten. Dessutom finns differenser i skallens konstruktion.[6]
Den långa smala svansen har en tofs vid slutet. Vikten ligger vid 65 gram.[7]
Vid matbrist går individerna i ide - vanligen mellan april och juni samt mellan september och oktober.[7] Födan utgörs av gröna växtdelar och några frön. Under våren äter Bobrinskis hästspringråtta ganska många insekter. Honor kan ha tre kullar per år med upp till 8 ungar men 3 eller 4 ungar är vanligare.[1]
Individerna har enkla bon som används bara en eller några dagar och mera komplexa bon som används längre tider. Bobrinskis hästspringråtta är nattaktiv. För övrigt antas att levnadssättet motsvarar de andra hästspringråttornas beteende.[7]
