mus musculus characteristics

In marked territories, intruders showed significantly lower aggression than the territory residents. Found on all continents (except maybe Antarctica) and in all biogeographic provinces; or in all the major oceans (Atlantic, Indian, and Pacific. This species, commonly called the western Mediterranean mouse, is distributed throughout Portugal across all but the northern fringe of Spain into the southern region of France. The best known mouse species is the common house mouse (Mus musculus). Critical bands and filter characteristics in the ear of the housemouse (Mus musculus) March 1976; Biological Cybernetics 24(1):35-42; DOI: 10.1007/BF00365592. The latter refers to a pathological condition causing mice to twitter constantly with a "song" resembling that of a cricket. In protected environments, however, they often live two to three years. Soon after this most young mice leave their mother's territory, though young females are more likely to stay nearby. Females experience a postpartum estrus 12-18 hours after giving birth. [64], House mice can sometimes transmit diseases, contaminate food, and damage food packaging. House mice often squeak to each other in the nest. House mice have an adult body length (nose to base of tail) of 7.5–10 centimetres (3–4 in) and a tail length of 5–10 cm (2–4 in). They commonly forage outdoors during the spring and summer, but retreat into buildings through the fall and winter to seek warmth and food. No known deaths have resulted from the disease. They are a brown to gray color and their belly is of a slightly lighter color. One female can have 5 to 10 litters per year, so the mouse population can increase very quickly. The vocalizations appear to differ between individuals and have been compared to bird songs because of their complexity. As many as seven separate species may be placed under Mus musculus, such as Mus domesticus, western European house mice, and Mus castaneus, southeastern Asian house mice. Also called "hoarding". The recent discovery of ultrasonic songs produced by male mice, when exposed to female sex pheromones, suggests that this behavior may be involved in mate choice. [49] Multiple mating by females and paternity confusion can decrease rates of infanticide. The former refers to a genetic strain with inner ear defects, causing the mice to weave, turn in circles, and wobble when they walk. muscle [mus´'l] a bundle of long slender cells (muscle fibers) that have the power to contract and hence to produce movement. In commensal populations, males come into contact with other males quite frequently due to high population densities and aggression must be mediated or the risk of injury becomes too great. House mice in buildings and other urbanized areas with close proximity to humans are known as commensal. [19] House mice, like most other rodents, do not vomit. Characteristically, mice are known to have a pointed snout, small rounded ears, a body-length scaly tail, and a high breeding rate. Mus spretus Lataste, 1883, is a small, wild (noncommensal) murine with a rounded muzzle and small eyes and ears. In the wild, populations are less stable and densities may be less than 1 mouse per 100 square meters. [60] Human domestication led to numerous strains of "fancy" or hobby mice with a variety of colours and a docile temperament. [46] This behaviour allows for an increase in both the transfer of sperm and paternity success, which in turn increases male fitness. Morphometric characteristics of the small and large intestines of Mus musculus during postnatal development Folia Morphol (Warsz). "Dancing" and "singing" mice are other names for house mice. [38] While females have the capability to produce ultrasonic calls, they typically do not do so during mating behaviour. 131, 163 – 175.CrossRef Google Scholar. Territoriality is not as pronounced in wild conditions, however. In the eastern Balkans (most of Bulgaria, Macedonia, the Torlak districts of Serbia), the "Mouse Day" (Bulgarian: Миши ден, Мишин ден) was celebrated on October 9 of the Julian calendar (corresponds to October 27 of the Gregorian calendar in the 20th and 21st centuries), the next day after the feast of St Demetrius. Nowak, R.M. The calls are most frequent during courtship when the male is sniffing and following the female; however, the calls continue after mating has begun, at which time the calls are coincident with mounting behaviour. The objective of this study was to quantify the population dynamics, morphological characteristics, and diet of rodents on Rangitoto Island (Hauraki Gulf, New Zealand) to provide information for the future development of an eradication strategy. In otherwords, Europe and Asia and northern Africa. young are born in a relatively underdeveloped state; they are unable to feed or care for themselves or locomote independently for a period of time after birth/hatching. [71], Rickettsialpox, caused by the bacterium Rickettsia akari and similar to chickenpox, is spread by mice in general, but is very rare and generally mild and resolves within two or three weeks if untreated. They are also known to kill lizards and have a large effect on native insects. Some populations are hybrids of different subspecies, including the Japanese house mouse (M. m. House mice tend to have longer tails and darker fur when living closely with humans. [76], Mice are the most commonly used mammalian laboratory animal, due to their relatively close relationship, and associated high homology, with humans, their ease in maintenance and handling, and their high rate of reproduction. To evaluate the colonization histories of the Japanese house mice (Mus musculus), phenotypic and genotypic admixtures of the subspecific traits were studied by evaluation of external body characteristics and mitochondrial gene elements. 1995. having the capacity to move from one place to another. In the wild state, house mice generally dwell in cracks in rocks or walls or make underground burrows consisting of a complex network of tunnels, several chambers for nesting and storage, and three or four exits. New Zealand had no land mammals other than two species of bat prior to human occupation, and the house mouse is one of many species that have been introduced. An important factor in the success of Mus musculus is its behavioural plasticity brought about by the decoupling of genetics and behaviour. Despite this, free-living populations of rats and mice do exist together in forest areas in New Zealand, North America, and elsewhere. It is one of the most abundant species of the genus Mus. (Holy and Guo, 2005). XXX. med. The es­trous cycle is 4-6 days long, with es­trus last­ing less than a day. Breeding occurs throughout the year. [30][31][32] In 2007, mice genetically engineered to produce the third type of cone were shown to be able to distinguish a range of colors similar to that perceived by tetrachromats.[29]. The tail, which is used for balance,[10][11][12] has only a thin covering of hair as it is the main peripheral organ of heat loss in thermoregulation[11] along with—to a lesser extent—the hairless parts of the paws and ears. If they are then exposed to male urine, they will come into estrus after 72 hours. The fitness of females increases in polyandrous lines due to more genetic diversity and greater litter size. They gnaw various materials to file down their growing teeth and keep the length under control. The Animal Diversity Web is an educational resource written largely by and for college students. [66][67][68] Some concern exists that women should not to be infected with LCMV during pregnancy. [28], The visual apparatus of mice is basically similar to that of humans but differs in that they are dichromats and have only two types of cone cells whereas humans are trichromats and have three. Polyandrous behavior is a common mating pattern in the subspecies Mus musculus musculus as well as its relative Mus musculus domesticus.[47]. Liz Ballenger (author), University of Michigan-Ann Arbor. House mice do not cause such serious health and economic problems as do Rattus norvegicus and Rattus rattus. fertilization takes place within the female's body. Kurta, A. British Journal of Cancer, 82(2): 446-451. Soc. reproduction in which fertilization and development take place within the female body and the developing embryo derives nourishment from the female. defends an area within the home range, occupied by a single animals or group of animals of the same species and held through overt defense, display, or advertisement, uses sound above the range of human hearing for either navigation or communication or both. Females establish a loose hierarchy within the territories, but they are far less aggressive than males. Mice are territorial, and one dominant male usually lives together with several females and young. reproduction that includes combining the genetic contribution of two individuals, a male and a female. [74], Gough Island in the South Atlantic is used by 20 species of seabirds for breeding, including almost all of the world's Tristan albatross (Diomedea dabbenena) and Atlantic petrel (Pterodroma incerta). Dominant males set up a territory including a family group of several females and their young. living in the northern part of the Old World. [48] Within a population, males and females show different levels of multiple mating. Mice are also a popular as pets. forest biomes are dominated by trees, otherwise forest biomes can vary widely in amount of precipitation and seasonality. The species M. booduga and M. cervicolor previously predicted to be common in the … House mice are generally poor competitors and in most areas cannot survive away from human settlements in areas where other small mammals, such as wood mice, are present. 1983. These populations are often limited by water or food supply and have large territories. The house mouse has been domesticated as the pet or fancy mouse, and as the laboratory mouse, which is one of the most important model organisms in biology and medicine. They have a slightly elongated snout, small black eyes that protrude somewhat with large scarcely haired ears. Vitality: growth and metabolism. To evaluate the colonization histories of the Japanese house mice (Mus musculus), phenotypic and genotypic admixtures of the subspecific traits were studied by evaluation of external body characteristics and mitochondrial gene elements. Highly adaptive, the house mouse has both behavioral and physiological traits—such as the ability to survive in buildings and aboard ships, a tendency to move into agricultural fields and leave when the habitat changes, and a rapid rate of reproduction—that allow it to thrive wherever humans do. having body symmetry such that the animal can be divided in one plane into two mirror-image halves. [69][70], House mice are not usually a vector of human plague (bubonic plague) because they have fewer infestations with fleas than do rats, and because the fleas which house mice normally carry exhibit little tendency to bite humans rather than their natural host. [47] Variation in number of males that females mate with occurs among a population. House mice are generally nocturnal, although some are active during the day in human dwellings. Mus musculus (Mouse) Status. In this case, all four families branch in similar manners because they are all of the same suborder, Myomorpha and also of the same super family Muroidea. female with litter Anatomy/Miscellaneous . Murine typhus (also called endemic typhus), caused by the bacterium Rickettsia typhi, is transmitted by the fleas that infest rats. [64], When infesting homes, house mice may pose a risk of damaging and compromising the structure of furniture and the building itself. Male aggression is also higher in noncommensal populations. [51] Another mechanism for avoiding inbreeding is evident when a female house mouse mates with multiple males. Mus musculus is generally considered both territorial and colonial when living commensally with humans. This enables M. musculus to adapt quickly and to survive and prosper in new environments. M. V. Vadell A B, I. E. Gómez Villafañe A B and R. Cavia A B C + Author Affiliations - Author Affiliations. Mouse mammary tumor virus infects human cells. [citation needed] They eat their own faeces to acquire nutrients produced by bacteria in their intestines. Sperm competition that arises from polygamy favors males with faster, more motile sperm in higher numbers, increasing male fitness. National Science Foundation Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. chemicals released into air or water that are detected by and responded to by other animals of the same species, having more than one female as a mate at one time. and J.L Paradiso. The re­cent dis­cov­ery of ul­tra­sonic songs pro­duced by male mice, when ex­posed to fe­male sex pheromones, sug­gests that this be­hav­ior may be in­volved in mate choice. usually attempt to maintain contact with vertical surfaces. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. They are native to India,[56][57] and later they spread to the eastern Mediterranean about 13,000 BC, only spreading into the rest of Europe around 1000 BC. Breeding occurs throughout the year, although wild mice may have a reproductive season extending only from April to September. Laboratory mice are typically highly inbred and may display characteristics thought to be "normal" that are actually the result of genetic drift, founder effects, etc. Grants DRL 0089283, DRL 0628151, DUE 0633095, DRL 0918590, and DUE 1122742. Sage, R., W. Atchley, E. Capanna. associates with others of its species; forms social groups. [23][24] The high level of male-male aggression, with a low female-female aggression level is common in polygamous populations. About one hundred years later, it arrived in North America with French fur traders and English colonists. [23] Commensal mice populations often have an excessive food source resulting in high population densities and small home ranges. In birds, naked and helpless after hatching. House mice generally live in close association with humans-- in houses, barns, granaries, etc. Cancer Research, 65 (15): 6651-6659. Mus musculus castaneus, cornered in a box. It was recently discovered that male mice produce complex, ultrasonic songs in response to female sex pheromones. Are life-history strategies of Norway rats (Rattus norvegicus) and house mice (Mus musculus) dependent on environmental characteristics? Pet mouse climbing on a soda bottle. The three widely accepted subspecies are increasingly treated as distinct species by some:[16][17], Two additional subspecies have been recognized more recently:[17], Many more subspecies' names have been given to house mice, but these are now regarded as synonyms of the five subspecies. [78], Many Southern Slavs had a traditional annual "Mouse Day" celebration. Dunn L. C. & Gluecksohn-Waelsch S., 1953b. The ancient Egyptians had a story about "The mouse as vizier". They are also capable of reproducing very rapidly, which means that populations can recover quickly from predation. [22], The social behavior of the house mouse is not rigidly fixed into species-specific patterns but is instead adaptable to the environmental conditions, such as the availability of food and space. Offspring fertilized by multiple males can compete more strongly for mother's resources and can lead to a decrease in body size and variation in body size. This material is based upon work supported by the [43], The polygamous behavior of female house mice promotes sperm competition, which affects both male and female evolutionary fitness. Mus musculus, like all rodents, has a single enlarged evergrowing incisor in each half of the upper and lower jaws. [9] When sexually mature, the most striking and obvious difference is the presence of testicles on the males. [43] Polygamous male house mice spend less time alone with pups. Acta genet. Odours from adult males or from pregnant or lactating females can speed up or retard sexual maturation in juvenile females and synchronise reproductive cycles in mature females (i.e. If two or more males are housed together in a cage, they often become aggressive unless they have been raised together from birth. the business of buying and selling animals for people to keep in their homes as pets. [23] Male-male aggression occurs in commensal populations, mainly to defend female mates and protect a small territory. Mice have highly developed hearing, taste, and smell senses. For example, one study suggests the possibility of a previously unsuspected early link between Northern Europe and Madeira on the basis of the origin of Madeiran mice. [6][7] House mice thrive under a variety of conditions; they are found in and around homes and commercial structures, as well as in open fields and agricultural lands. In the wild, most mice do not live beyond 12-18 months. The standard species karyotype is composed of 40 chromosomes. Additional support has come from the Marisla Foundation, UM College of Literature, Science, and the Arts, Museum of Zoology, and Information and Technology Services. Ballenger, L. 1999. Their fur ranges in color from light brown to black, and they generally have white or buffy bellys. Average life span is about 2 years in captivity, but individuals have lived for as long as 6 years. Some individuals spend the summer in fields and move into barns and houses with the onset of cool autumn weather. [39] Females who mate with multiple males tend to produce both pups in greater numbers,[39] and with higher survival rates,[44] increasing female fitness. The ADW Team gratefully acknowledges their support. Occasionally, subordinate males may occupy a territory or males may share territories. Overall, populations are flourishing and are in fact aided by human construction of houses, barns, and other structures. uses smells or other chemicals to communicate. In addition, they contribute to the spread of diseases such as murine typhus, rickettsial pox, tularemia, food poisoning (Salmonella), and bubonic plague. Despite this, they rarely travel more than 50 feet from their established homes. Illustrations Maps … [citation needed] They live in a wide variety of hidden places near food sources, and construct nests from various soft materials. Characteristics of muscle synonyms, Characteristics of muscle pronunciation, Characteristics of muscle translation, English dictionary definition of Characteristics of muscle. While rat fleas are the most common vectors, cat fleas and mouse fleas are less common modes of transmission.
