The dusky hopping mouse, is a small rodent endemic to Australia, inhabiting desert regions characterised by sand dunes. Populations have experienced significant declines since the arrival of Europeans, and continue to be subject to threatening processes. It is currently listed as a threatened species.
The Muroidea are a large superfamily of rodents, including mice, rats, voles, hamsters, lemmings, gerbils, and many other relatives. Although the Muroidea originated in Eurasia, they occupy a vast variety of habitats on every continent except Antarctica. Some authorities have placed all members of this group into a single family, Muridae, due to difficulties in determining how the subfamilies are related to one another. Many of the families within the Muroidea superfamily have more variations between the families than between the different clades. A possible explanation for the variations in rodents is because of the location of these rodents; these changes could have been due to radiation or the overall environment they migrated to or originated in. The following taxonomy is based on recent well-supported molecular phylogenies.
The water voles are large voles in the genus Arvicola. They are found in both aquatic and dry habitat through Europe and much of northern Asia. A water vole found in Western North America was historically considered a member of this genus, but has been shown to be more closely related to members of the genus Microtus. Head and body lengths are 12–22 cm, tail lengths are 6.5–12.5 cm, and their weights are 70–250 g. The animals may exhibit indeterminate growth. They are thick-furred and have hairy fringes on their feet that improve their swimming ability.
Euryoryzomys russatus, also known as the russet oryzomys, russet rice rat, or big-headed rice rat, is a species of rodent in the family Cricetidae. It is a member of the genus Euryoryzomys, which was split off from Oryzomys in 2006. It was first described by Johann Andreas Wagner in 1848. It is found in southern Brazil, eastern Paraguay and northeastern Argentina. It is considered a large species in its genus, with a reddish-brown coat, long tail length, and large skull. It is a terrestrial rodent, spending its time foraging for seeds, fruits, and insects. It is listed by the IUCN as least concern, although studies have shown it to be influenced by anthropogenic disturbances. Predators consist of small members of the order Carnivora.
Vesper mice are rodents belonging to the genus Calomys. They are widely distributed in South America. Some species are notable as the vectors of Argentinian hemorrhagic fever and Bolivian hemorrhagic fever.
The shrewlike rats, genus Rhynchomys, also known as the tweezer-beaked rats are a group of unusual Old World rats found only on the island of Luzon in the Philippines. They look a great deal like shrews and are an example of convergent evolution. Shrewlike rats evolved to be vermivores and insectivores feeding on soft-bodied invertebrates associated with leaf litter.
The plains rat(Pseudomys australis), also known as the palyoora, plains mouse and eastern mouse, is a conilurine rodent native to arid and semi-arid Australia. Referred to as the pallyoora or yarlie by Indigenous groups, the plains rat was once widely distributed across central Australia, including north-west New South Wales and south-west Queensland; however, habitat degradation due to grazing, introduced predators and drought have contributed to its decline. Consequently, the plains rat has been listed as 'presumed extinct' in New South Wales and Victoria, 'endangered' in the Northern Territory and Queensland and 'vulnerable' in Western Australia and South Australia. While recent research has indicated the presence of the plains rat in areas such as the Fowlers Gap and Strzelecki Desert regions of New South Wales and within the Diamantina National Park in Queensland, there are only five sub-populations currently recognised nationally, none of which coincide with recent discoveries of the plains rat. As the current population trend of the plains rat has been listed as 'declining' by the International Union for the Conservation of Nature (IUCN), the IUCN conservation status for the species is 'vulnerable'.
The Patagonian chinchilla mouse is a species of rodent in the family Cricetidae. It was first described by George Robert Waterhouse in 1839. It is found in Tierra del Fuego and neighboring areas of southernmost Argentina and Chile.
Graomys is a genus of rodent in the family Cricetidae. It contains the following species:
Hylomyscus is a genus of rodent in the family Muridae endemic to Africa.
The Mexican volcano mouse is a species of rodent in the family Cricetidae endemic to high elevation areas of the Trans-Mexican Volcanic Belt.
Oligoryzomys magellanicus, also known as the Patagonian colilargo and the Magellanic pygmy rice rat, is a species of rodent in the genus Oligoryzomys of the family Cricetidae. It is found in the southernmost parts of Argentina and Chile, including Tierra del Fuego and other outlying islands. Its karyotype has 2n = 54 and FNa = 66.
The yellow-rumped leaf-eared mouse, otherwise known as the Patagonian leaf-eared mouse, is a species of rodent in the family Cricetidae and order Rodentia. It is the most widespread member of the genus.
The blunt-eared bat or Peruvian crevice-dwelling bat is a species of bat in the family Molossidae. It is monotypic within the genus Tomopeas and subfamily Tomopeatinae. It is endemic to Peru, where it is considered critically endangered. It is threatened by habitat loss.
The big-eared woodrat is a nocturnal rodent of the woodrat genus Neotoma, in the family Cricetidae. Closely related to, and formerly included in the species Neotoma fuscipes, it is endemic to western North America and occurs west and south of the Salinas Valley from the California Coast Ranges south of Monterey Bay to northern Baja California, as well as in the Sierra Nevada, extending north to the South Fork American River.
The delicate salt flat mouse is a sigmodontine rodent species in the family Cricetidae from South America. It is the only species in the genus Salinomys. Its habitat is scrublands bordering salt flats in the Monte Desert area of central western Argentina at elevations around 400 m. The closest relatives of the species are the chaco mice (Andalgalomys).
Hassalstrongylus is a genus of nematode worms that infect mostly muroid rodents from eastern North America to South America. The genus is part of the Heligmonellidae and related to genera like Stilestrongylus.
Choya is a village and municipality in the Andalgalá Department of Catamarca Province in northwestern Argentina. The town is located on National Route 47. It is located along the Río Choya.
