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 Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species. Members of this subfamily are called murines. In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents.
The yellow-necked mouse, also called yellow-necked field mouse, yellow-necked wood mouse, and South China field mouse, is closely related to the wood mouse, with which it was long confused. It was only recognised as a separate species in 1894. It differs in its band of yellow fur around the neck and in having slightly larger ears and usually being slightly larger overall. Around 100 mm in length, it can climb trees and sometimes overwinters in houses. It is found mostly in mountainous areas of southern Europe, but extends north into parts of Scandinavia and Britain. It facilitates the spread of tick-borne encephalitis to humans and is a reservoir species for the Dobrava virus, a hantavirus that is responsible for causing haemorrhagic fever with renal syndrome.
The western harvest mouse is a small neotomine mouse native to most of the western United States. Many authorities consider the endangered salt marsh harvest mouse to be a subspecies, but the two are now usually treated separately.
Zygodontomys brevicauda, also known as the short-tailed zygodont, short-tailed cane mouse, or common cane mouse, is a species of rodent in the genus Zygodontomys of tribe Oryzomyini.
Chiropodomys is a genus of Old World rats and mice native to Southeast Asia and northeast India. They are tree-dwelling, very small mice, mostly found in tropical rainforest. In total six extant species have been identified, but only one of these, Chiropodomys gliroides, is common and widely distributed, and has been extensively studied.
The Palawan pencil-tailed tree mouse is a species of arboreal rodent in the family Muridae. It is known from lowland forest near sea level, coconut groves, and bamboo thickets. It is endemic to the Palawan Faunal Region in the Philippines. It has been recorded on Balabac, Busuanga, Palawan, Dumaran, and Calauit islands.
The Indomalayan pencil-tailed tree mouse or simply pencil-tailed tree mouse is a species of arboreal rodent in the family Muridae. It is found in northeastern India, southern China, Myanmar, Thailand, Laos, Cambodia, Vietnam, Peninsular Malaysia, and Indonesia. This locally abundant but patchily distributed species occurs in primary and secondary forests, without affinity to particular forest types. It can suffer from deforestation and is sometimes harvested for consumption.
Koopman's pencil-tailed tree mouse is a species of arboreal rodent in the family Muridae. It is endemic to Pagai and Siberut islands in the Mentawai Islands, off the western coast of Sumatra in Indonesia. Its natural habitat is tropical primary lowland forest. It is threatened by habitat loss (logging).
The gray-bellied pencil-tailed tree mouse is a species of arboreal rodent in the family Muridae. It is endemic to Borneo where it is known from Gunung Kinabalu and from Long Petak in northern Kalimantan (Indonesia). It probably has wider distribution than currently documented. Its natural habitat is montane tropical forest. It is threatened by habitat loss.
The small pencil-tailed tree mouse or lesser pencil-tailed tree mouse is a species of arboreal rodent in the family Muridae. It is endemic to Borneo where it is only known from Sabah and Sarawak (Malaysia) and from southern Kalimantan (Indonesia), although it likely occurs more widely.
The golden Oldfield mouse or golden thomasomys is a species of rodent in the family Cricetidae. It is found in Colombia, Ecuador, Peru, and Venezuela. Both the common and genus name commemorate the British zoologist Oldfield Thomas who worked at the Natural History Museum, London and studied South American rodents.
Gracilinanus is a genus of opossum in the family Didelphidae. It was separated from the genus Marmosa in 1989, and has since had the genera Cryptonanus, Chacodelphys, and Hyladelphys removed from it.
The D'Entrecasteaux Archipelago pogonomys, also known as the D'Entrecasteaux Archipelago tree mouse, is a species of prehensile-tailed rat from the family Muridae that is endemic to Papua New Guinea. It was once considered to be a subspecies of the Large Tree Mouse. Deforestation is posing a threat to the species, but it has been suspected that the species has some degree of tolerance towards disturbance of its habitat.
Hydromyini is a very large, diverse tribe of muroid rodents in the subfamily Murinae. They are the dominant native rodents in Australasia and one of only two native rodent groups there, the other being the R. fuscipes group of the genus Rattus in the tribe Rattini. They are also found in parts of Southeast Asia.
