The house mouse is a small mammal of the order Rodentia, characteristically having a pointed snout, large rounded ears, and a long and almost hairless tail. It is one of the most abundant species of the genus Mus. Although a wild animal, the house mouse has benefited significantly from associating with human habitation to the point that truly wild populations are significantly less common than the semi-tame populations near human activity.
The harvest mouse is a small rodent native to Europe and Asia. It is typically found in fields of cereal crops, such as wheat and oats, in reed beds and in other tall ground vegetation, such as long grass and hedgerows. It has reddish-brown fur with white underparts and a naked, highly prehensile tail, which it uses for climbing. It is the smallest European rodent; an adult may weigh as little as 4 grams (0.14 oz). It eats chiefly seeds and insects, but also nectar and fruit. Breeding nests are spherical constructions carefully woven from grass and attached to stems well above the ground.
The Muridae, or murids, are either the largest or second-largest family of rodents and of mammals, containing approximately 870 species, including many species of mice, rats, and gerbils found naturally throughout Eurasia, Africa, and Australia.
Pseudomys is a genus of rodent that contains a wide variety of mice native to Australia and New Guinea. They are among the few terrestrial placental mammals that colonised Australia without human intervention.
The wood mouse is a murid rodent native to Europe and northwestern Africa. It is closely related to the yellow-necked mouse but differs in that it has no band of yellow fur around the neck, has slightly smaller ears, and is usually slightly smaller overall: around 90 mm (3.54 in) in length and 23 g in weight. It is found across most of Europe and is a very common and widespread species, is commensal with people and is sometimes considered a pest. Other common names are long-tailed field mouse, field mouse, common field mouse, and European wood mouse. This species is a known potential carrier of the Dobrava sequence of hantavirus which affects humans and may pose serious risks to human health.
Peromyscus maniculatus is a rodent native to eastern North America. It is most commonly called the eastern deer mouse; when formerly grouped with the western deer mouse, it was referred to as the North American deermouse and is fairly widespread across most of North America east of the Mississippi River, with the major exception being the lowland southeastern United States.
The bobak marmot, also known as the steppe marmot, is a species of marmot that inhabits the steppes of Eastern Europe and Central Asia. It is a social animal and inhabits steppe grassland, including cultivated field borders. It hibernates for more than half the year. Litter sizes average about five offspring and it takes three years for the young marmots to reach sexual maturity. Male offspring leave the home colony after their second winter, and about 60% of mature females give birth in any one year.
The genus Mus or typical mice refers to a specific genus of muroid rodents, all typically called mice, though the term can be used for other rodents. They are the only members of the tribe Murini. However, the term mouse can also be applied to species outside of this genus.
The hispid pocket mouse is a large pocket mouse native to the Great Plains region of North America. It is a member of the genus Chaetodipus.
The grey dwarf hamster, grey hamster or migratory hamster is a species of rodent in the family Cricetidae. Its range extends from Eastern Europe through the Middle East, Russia and Central Asia to Mongolia and western China. The grey dwarf hamster has grey fur and a head-body length ranging from 85 to 120 mm. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The Macedonian mouse is a species of rodent in the family Muridae and order Rodentia. This rodent lives in the area from eastern Georgia and western Bulgaria to Israel. It is considered part of a Palearctic group along with three other species: the house mouse, steppe mouse, and Algerian mouse.
The Algerian mouse, also known as the western Mediterranean mouse, is a wild species of mouse closely related to the house mouse, native to open habitats around the western Mediterranean.
The sandy inland mouse is a species of rodent in the family Muridae. Also known as the Hermannsburg (Mission) false-mouse or Hermannsburg mouse, it is endemic to Australia and found widely yet sparsely through arid and semi-arid areas.
The Great Basin pocket mouse is a species of rodent in the family Heteromyidae. It is found in British Columbia in Canada and the western United States.
The Pacific jumping mouse is a species of rodent in the family Zapodidae. Found in Canada and the United States, its natural habitats are temperate grassland and swamps.
The St Kilda field mouse is a subspecies of the wood mouse that is endemic to the Scottish archipelago of St Kilda, the island 40 miles (64 km) west of Benbecula in the Outer Hebrides, and 100 miles (160 km) from mainland Scotland. Unique to the islands, the mouse is believed to have arrived on the boats of Viking settlers more than a millennium ago. It is not to be confused with the St Kilda house mouse, a subspecies of the house mouse which is now extinct.
Ohno's law was proposed by a Japanese-American biologist Susumu Ohno, saying that the gene content of the mammalian species has been conserved over species not only in the DNA content but also in the genes themselves. That is, nearly all mammalian species have conserved the X chromosome from their primordial X chromosome of a common ancestor.
Mus is a subgenus of the rodent genus Mus.
